I have multiple questions pertaining to root and ROMs, any advice on any one of them would be appreciated. My questions surround a Samsung Galaxy S 4G, and a Nexus 7 (2012).
Samsung Galaxy S
ROM Manager
The SGS4G XDA forums have coined it as the "ROM Mangler", my model of Galaxy S is not a compatible device. However, every ROM I've flashed so far has included Clockworkmod5 or Clockworkmod6 (which are only accessible through Recovery). I naturally want to use this app to manage my ROMs on this device, but am wondering if I should or if I will be able to?
Nexus 7, and other Google/Nexus devices
OTA (over-the-air) software updates
I read a comment from a guy on Youtube that said he rooted his Nexus 7, but eventually received a software update from Google. He said he had to re-root his device after this. I am assuming the notification never went away, and he decided to install the update. How would I prevent something like this from happening? Should I install a ROM immediately after rooting??
Internal Storage
My Nexus 7 doesn't have an SD card, but has 32GB of internal storage space. My file explorer shows that the device has an 'sdcard' folder, but wouldn't that folder be wiped if I decided to root and flash a ROM on this device?? How would I prevent this scenario from happening?
General
Busybox
What is Busybox, and should it be installed? I watched a Youtube video suggesting to install it anyway, but I highly doubt I will ever use or need it. After rooting my Galaxy, I noticed Busybox was automatically installed. However after flashing several ROMs, I notice that some of them don't come with Busybox pre-installed.
Cyanogenmod
I currently have an unofficial Cyanogenmod 10.1 (w/Android 4.2.2) ROM installed on my Galaxy. But what is Cyanogenmod exactly, and why is it a big name in the ROM community? I've heard a lot about AOKP too.
SuperUser
My current ROM is missing a Superuser app. Should I install a Superuser app, and does it matter which one I choose?
If a Superuser app has already been pre-installed with a ROM, is updating to the Play Store version a good idea? Are there any consequences to installing a different superuser like Super SU or SuperUser from Clockworkmod? Is uninstalling one Superuser for another a good idea?

To answer your questions:
Samsung Galaxy S
ROM Manager
ROM Manger has been buggy for a while now and can cause a lot of problems on certain devices, I would personally avoid it for the time being. That being said the best way to manage your ROM's (And any other Kernel, or MOD's you may want to flash) is too boot your device into recovery mode by using the key combination described in this post, or by running the following command from ADB on your computer:
Code:
adb reboot recovery
Once in recovery, you can flash any ROM that you pushed to your phones sdcard. Make sure to always perform a NANDROID backup of your current setup in recovery mode, before installing a new ROM, Kernel, or other MOD (Such as editing your build.prop file). Also before flashing anything in recovery make sure it is intended for your device and that you read and re-read, and re-read again the instructions on how to properly flash the file.
Nexus 7, and other Google/Nexus devices
OTA (over-the-air) software updates
It is always assumed that any OTA update you apply will break root and that you will have to re-gain root access by re-rooting your device. You can disable OTA updates a couple of different ways. One method is to use an app such as FOTAkill to prevent OTA updates from happening. Another method is to use an app such as Titanium Backup to freeze and disable certain system apps that control OTA updates from being sent and received. Lastly, you can install a custom ROM to prevent OTA updates from being pushed to your device.
Internal Storage
This is a great question. The way the Nexus 7 and other devices that don't have an actual physical sdcard slot handle this is the sdcard folder you see in the file explorer acts as an emulated sdcard. So this way when you go to install a custom ROM in recovery mode when the ROM installation requires you to wipe everything the contents of the emulated sdcard will be untouched and remain as if it were a actual physical sdcard.
General
Busybox
Busybox is a series of stripped down GNU utilities and command line applets, you can find more about Busybox and what it is here. As far as needing it in the beginning you might not need it but as you get more familiar with modifying devices is comes in very handy for performing certain operations and tasks and is worth installing just to have for it's functionality. A lot of root programs push the su binary, a Superuser.apk, and often times the busybox binary. Not all ROM's choose to include busybox but it's handy to have like I mentioned for it's functionality.
Cyanogenmod
Cyanogenmod is an aftermarket firmware distribution you can find more about it here. As for why is it famous it was one of the first well know custom ROM's and soon grew to include support for a vast amount of devices you can find more about the history of Cyanogenmod here. AOKP is another well know ROM that stands for Android Open Kang Project, it first came about when Android 4.0 Ice Cream Sandwich was released you can learn more about AOKP here.
SuperUser
If your current ROM is missing a Superuser app you may install one from the Play Store, it does not matter which one you choose it is personnel preference but I would use either Chainfire's SuperSU app or Koush's Superuser app. Updating a pre-installed Superuser app to the latest Play Store version is fine. There are no consequences to installing one Superuser app and uninstalling another one it's a matter of personnel preference which one you want to use. Keep in mind if you uninstall one Superuser app and then install a different one it may ask you to update the su binary (Which it should ask you if you want to do that once you launch the app for the first time) before it will function properly.
If you have any other questions let me know I'll be happy to answer them or elaborate on anything that may still be unclear to you.
EDIT: Problem is resolved. After I learn very much:
I made a video, cause there is no helpful video with Safestrap 4. Only with Version 3 and this way is wrong now!
I also write a blog about that helpful storry and links that will help other's.
Hello,
i started to root my Apollo 8.9/LTE with Tutorials from here and a translation in german. I live in germany.

Root Tool
Thats what i do
Rollback to OS 3.2.8 was great
Update to 4.5.2 was also ok
I rootet my Apollo, it works - i tested it
After that i renamed the DeviceSoftwareOTA.apk from Kindle in the priv-app
Now i copied all needed GAPPS files to the system Folder except the descripited
After that i restart my Apollo and now the Problems start
After restart

I have to choise a Language but there was no german
Also i had no WIFI Connection, so the Assistent start the Option to connect with WIFI
This work, but at the wifi there is a X and in the Assistent i habe no Internet connection
I use my SIM Card to get a internet connection (This work) but the Assistent need a WIFI
Also i lost my root and get Denied when i try to copy/change with a older version befor April 15 or delete the GAPPS Files in the system Folders
I can start/install Apps with apk, at the apollo i only can use the settings. I have no menu or keys
Thats what i tried
I can use adb and install ES Datei Explorer or SuperSu
I used KingRoot, it dosn't work
I copied the mod Rollback to 3.2.8 bin File in the root folder, but Apollo dont use this file, maybe cause i renamed the OTA Systemfile
I made a reset of the Apollo, but the google Assistent is in the systemfiles and start even after a reset
My Apollo
Has Fire OS 4.5.2
The DeviceSoftwareOTA.apk is renamed
I only can Read NOT Write in the system folders
I can use adb and connect to the Apollo
I tried so much the last 2 days so i hope you got a hint for me.

Nice post; well documented.
You made some serious mistakes (come back to that later) and have a challenge ahead recovering your device. Based on others experiences there is some type of conflict between gapps and the stock launcher. That is probably why you are not seeing soft buttons, keyboard, etc. The only known solution is to temporarily use a different launcher to regain control of your device long enough to reroot. Problem is your device will revert back to the stock launcher on a number of different events including pressing the home key which frequently doubles as 'back' on FireOS. You then have to reinstall the non-stock launcher or find some way to make FireOS treat it as primary.
General overview:
- grab a copy of Nova or Apex (other launchers will probably work too)
- install via 'adb install' (research if unfamiliar)
- if all goes well you should regain temporary use of soft buttons and keyboard
- stay away from home key if possible as it will immediately restore the compromised stock launcher
- attempt to reroot your device with Kingroot. This should be safe given OTA is blocked. You many need to install Kingroot via adb. Once launched Kingroot needs an internet connection to do its magic; hopefully it will pick that up via your sim card
- you can also try rooting with CVE-2014-4322 exploit.
Once you are rooted there are several paths that can be pursued. Since you have a LTE device installing Safestrap and a different ROM probably isn't the best option. Nor is reinstalling gapps on FireOS as you will face an ongoing series of battles (conflicts) between Amazon and Google frameworks. You may need to roll back and upgrade again to fully resolve the launcher conflict.
Discussion for a different post. See if you can get rooted first.

You can't change FireOS versions because you previously blocked OTA by renaming DeviceSoftwareOTA.apk. This file is required to perform rollbacks/upgrades. You will need to obtain root permissions to restore the original filename.

OK. With this file the update Start. But befor the Update load from amazon Website this takes first a look on the SDCard. Wright?

After enabling OTA put your device in airplane/flight mode to prevent updates from downloading. Make sure your device is stable (starts/functions normally) before attempting a rollback/update. I also advise allowing your device to upgrade to 4.5.5 (you will loose root) and then restart the rollback procedure from there.

Thx for your words.
I installed a launcher and restart but also had no buttons. But a other way was it.
I GOT IT!!
I dont have permission on system folder with ES Datei Explorer, but now i use adb.
I found a post here how to change permission with adb
adb shell
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
chmod 755 /system/app
Now i rename the file with mv MYNAMEOFOTA to DeviceSoftwareOTA.apk
After i used the gifroot Files But i got a message that it wouldnt work with this kernel.
So i dont know exactly which way was it.
But now to my serious mistakes. Can you tell me please what you mean? Cause I love this amazon hardware but I hate the amazon Fire OS and i love GMail, sheets, Maps, and other good apps from Google. So i need root.
All works bevor i push the GApps. So what is the better way. I know I have to read much more bevor i start again. Cause the Apollo is tricky.
I wait for a answer of you bevor i rollback to 3.2.8. I can wait.

Congratulations! Glad you were able to make some progress. Unfortunately, you are not out of trouble yet. Do not change permissions on any other files as FireOS is very sensitive and sometimes will not start if permissions are not as expected. Especially on 'system' files and folders.
Two concerns with the approach you took:
- using an outdated mod guide not published on XDA. Some of the techniques are old or no longer recommended
- attempting to install GApps on FireOS. Amazon and Google frameworks do not play nice together. While some have got it to work acceptably there are almost always problems, some quite serious.
A better approach is to use a twrp (recovery) emulator called Safestrap. Once installed you can install a limited selection of high quality ROMs that offer full access to the Google Play store. You may be familiar with the names: Nexus and CM11. They essentially turn your Kindle into a generic android tablet. You can even use native Amazon apps like Kindle reader.
The downside is LTE is not well supported by these roms. If you use your tablet off WiFi and need LTE then you have a tough decision to make:
1) Forgo LTE in favor of a rom with full Google Play access
2) Retain LTE and FireOS with limited access to Google services and apps
You don't have to make that decision now. First step is to rollback to 3.2.8, upgrade to 4.5.2, obtain root and block OTA. In a previous post I suggested upgrading to 4.5.5 first. I am stepping away from that suggestion to streamline the process. However, there is additional risk going from 4.5.2->3.2.8 because if anything goes wrong you could end up bricking your device. Going from 4.5.2->4.5.5 is less risky but adds another step.
There are many posts on XDA detailing the rollback/upgrade/root/blockOTA/Safestrap/rom process. Start here and spend some time reading. I did not pick this thread because it was the 'best'; just one I happen to remember contributing to in recent days. But it will lead you to other helpful posts that lead to even more posts ...
As always:
- ask questions if unsure; never assume or guess
- keep WiFi off (airplane/flight mode engaged) to prevent OTAs when upgrading or rolling back. Consequences are large: an OTA can (and likely will) permanently brick your device.
- make sure you fully understand the procedures, expected outcomes and recovery options if things go wrong
- only use files posted on XDA (links ok too)
- a fresh mind helps; take a break when tired. Your device will wait.
Good luck.

The again a lot.
I need my Mobile Internet. Not really LTE but at least 3G! But LTE get better here in Germany so it would be nice.
I like CM. I already flashed my Samsung S3, my wife S3 Mini, and my 2 Amazon's Tate.
That's why I bought the Apollo and hope after 1 year or so there will be a custom ROM with LTE working. So if someone interested I will flash a Custom Rom, life a time without Mobile Internet and help the developer with sending log files, or other needed things.
No I started reading! But I will post again here that other can read and learn from my mistakes.

FYI - you can find the Safestrap compatible CM11 rom thread here. As I recall some aspects of LTE/3G work ok. Skim through the posts for more detail. Might be a non-issue for your needs.

After i was short befor to brick my Apollo, maybe I would first Going from 4.5.2 > 4.5.5 and then 3.2.8 > 4.5.2.
But i dont read a hint with a link to 4.5.5. Can I download ist from here Davey?
Also i take a look in my router and he block some IPs when I used Kingroot on my PC yesterday.
14.17.41.155
202.77.59.49
163.177.71.157
120.198.203.149
103.7.29.30
They come from Hongkong and Bejiing. Is it possible that that was the reason Kingroot couldn't root my Apollo?

I can't speak to what IPs Kingroot uses. There have been various reports of it being slow or temporarily not working. Perhaps due to network congestion. Usually clears up after a few hours.
If you have restored DeviceSoftwareOTA.apk you can simply enable WiFi (disable airplane/flight mode) and allow the device to receive an OTA and self-update to 4.5.5. This is actually a good test OTA functionality is working which is also required for manual rollbacks/upgrades.
There is another option that does not involve rollbacks/upgrades: If you can obtain root you can then attempt to install Safestrap v4 followed by CM11 or Nexus v4 (you can also 'repair' FireOS using this method). Both Kingroot and Safestrap require interactive access. You don't need to type anything (so keyboard doesn't need to display), just tap an on-screen button or two. You would need to install apks via adb and then have enough control over your device to launch the app. Not easy or intuitive.
I will caution there is risk with either path (upgrading FireOS or installing Safestrap on a dysfunctional device). You have to weight the risks and take the course the feels most comfortable. There are no guarantees.
Reminder: do not do a 'factory reset' from the native recovery menu unless recommended by an experienced contributor, especially after rooting or installing Safestrap.
Now all is ok again. I am so joyful.
First Download Safestrap from here
Downloaded and Follow the instructions here
Now i can start with a new and clean Android on a good Amazon Hardware
Installed Safestrap on my damaged Fire OS 4.5.2
Than install a recovery in the Safestrap APP
After that i made a slot with 1200 System/1500 Data/1000 Cache
Active the slot
go into Wipe Menu and Swipe to perform a factory reset
Go in the Install Menue and install CM11, GAPPS and SuperSu
Now i started in CM11
Again thx to Davey126.
My stock ROM is still the damaged where I mixed amazaon and google framework. What can i do?
Active the Stock slot, start into my damaged Fire OS
Push with adb a Fire OS 4.5.5 to the sdcard
Or make a OTA over the WLAN from amazon?
Or (in the video says: NEVER touch the stock at Safestrap) Install a Fire OS bin in Safestrap to witch slot?

Excellent - glad to hear the progress!! However, there are some important changes needed that will greatly improve your CM11 experience (battery life, performance, stability). Some of this contradicts information in the video and recommendations from other versions of Safestrap.
The use of secondary slots is not recommended in Safestrap v4:
WiFi only works with CM11; Nexus v4 and Stock FireOS will fail to make a connection
Only 2 of 4 CPU cores are utilized resulting in poor performance under load
CPU runs at maximum speed at all times (no throttling) resulting in high battery use when idle
GPU does not throttle
Device never enters 'deep sleep'; radios remain active at all times
Backups can not be migrated between slots; flashing a secondary slot backup to the stock slot will brick device
Slot storage must be allocated in advance and can not be adjusted (must delete/recreate/reflash rom)
Recommended path:
Delete secondary slot (this will destroy your CM11 installation)
Flash CM11, GApps, SuperSu in stocki slot; this will overwrite FireOS in stock slot
This means your device will be running CM11 with no access to FireOS. However, if needed you can replace CM11 with FireOS 4.5.2 from this thread. Note the images are customized for Safestrap; flashing a unmodified stock image will brick your device.
Miscellaneous:
NEVER perform a 'factory reset' from the native recovery menu; your device will brick
Make a backup of the stock slot from within Safestrap (it will be large); move to a host PC for safe keeping
Always keep a flashable copy of CM11 image on the device (in the root of sdcard) for emergency recovery. Safestrap v4 can not communicate via wifi, bluetooth or tether. If CM11 fails to boot your only option is to reflash an OS (CM11, Nexus or FireOS) from within Safestrap recovery. If a Safestrap compatible/flashable image is not already on the device you can not recover from this type of failure.
Safestrap may appear to be a full blown recovery but it is actually a TWRP emulator that runs within the system partition and has dependencies on other Amazon components (bootloader, native recovery, etc) that remain on your device from the previous FireOS 4.5.2 installation. Be careful with advanced tools that run at a low level. It is possible to 'damage' your device to an extent that it can not be recovered. Ask first if uncertain.
questioning asking
This is so interesting. So sorry for my allways following questions. You said I should ask, but maybe also other can have a answer for me. This also cost your time.
So if you can't answer its ok. Or if there are only some hint words that will be a help for me to find out more. Whatever.
I am more than thankfull for that help to find out more about Android.

Ok, a next thing that i can search for.

With secondary slot you mean the ROM Slot 1, cause the Stock will be the first slot maybe?
I don't will go back to the Fire OS cause i have a Fire TV Stick and a Raspberry for that. If i still think so in some months i also can flash the Stock Rom with a CM Image? But its not necessary cause i have my CM11 or maybe in the future CM13 in the ROM Slot 1. Or are they more reasons for that step?

[*] Always keep a flashable copy of CM11 image on the device (in the root of sdcard) for emergency recovery. Safestrap v4 can not communicate via wifi, bluetooth or tether. If CM11 fails to boot your only option is to reflash an OS (CM11, Nexus or FireOS) from within Safestrap recovery. If a Safestrap compatible/flashable image is not already on the device you can not recover from this type of failure.

I dont know, at this time, so much from safestrap. But i take look in it, and i can use ADB Sideload, Mount a USB Storage. Maybe also to reboot into the Download.
Is a push from adb or a Backup on a USB not also a way to restore a damaged Custom ROM.
Like
Start into Safestrap
Wipe my Slot with the CM11 or delete ist and create it again
Push with adb a new file of CM11, GApps, SuperSu into my data permission
And after that flash it to the Data Partition

How i can find out what Low Level tools are?
I think a recovery like TWRP is one.
I also use Tasker or BusyBox. They can make also deep things on my system. Also Low Level?
When ends the Low Level and start the Deep System?

Yes - delete all ROM slots (1-n) that you created. Bottom line: you only want to use the Stock slot.

You do not want to maintain multiple slots (ROM images) in Safestrap v4. When you switch ROMs you overwrite the existing ROM in the Stock slot. You can overwrite CMxx with FireOS. At present CM12 and CM13 are not compatible with Safestrap v4. Do not attempt to flash any ROM image other than those specifically listed as "Safestrap Compatible".

"Native recovery" is the one supplied by Amazon accessible via <power> + <vol-up> from a cold start. NEVER use the 'factory reset' function from this menu when Safestrap v4 is installed; your device will brick.

None of these features work with Safestrap. Think of Safestrap as a virtual machine with ROMs running inside (technically inaccurate but conceptually convenient). You can only make full use ADB after portions of the ROM are up and running. If the ROM is damaged/unbootable you must do all repairs from within Safestrap. At present Safestrap v4 can not communicate with the outside world; all repair tools/images must be 'on board' (preloaded).

Probably repetitive but you do not want to recreate ROM Slot 1. Delete it and then flash CM11 (or Nexus v4 or FireOS) to the Stock slot.

- You can not use 'native' TWRP on your system as the bootloader is locked and can not be unlocked. Safestrap emulates TWRP.
- Tasker and BusyBox are fine
- Be careful with Xposed modules or other 'tweaks' that might cause your device to become unbootable.
Bottom line: enjoy CM11 and the apps that can be installed from the Play Store. Resist the temptation to customize further. If your device freezes or becomes unbootable you may not be able to recover.

Oh my god. Again I trust a old Video. More later
So i install again.
First i make a backup (over WLAN) from my Stock Rom. I didn't get connection over USB at my PC neither connect a USB Stick to the Micro USB Slot. That's may what you mean that Sfestrap works like a virtual mashine.
So i CHECK if all files are at my root folder in the stock
After that i Wipe the Stock Rom
After that Flash all needed files and install like the last time but this time into the Stock Rom

Good! Please confirm that you are now running CM11 in the Stock slot.
Assuming 'yes' you can (and should) remove all other slots if still present. Benefits:
- recover 3-4 Gb of permanent storage on your device and return it to the stock slot
- avoid potential confusion while in Safestrap recovery which could possibly lead to a bricked device
Once everything is stable boot into CM11 and move the large backup files to a host via tether (fastest), WiFi or Bluetooth. You do not need to keep backups on your device for recovery purposes; only the smaller ROM image.
You can not attach a flash/thumb drive or any other USB device (including keyboards/mice) to the micro-USB port as HDX devices lack OTG support at the hardware level. An unfortunate design choice by Amazon and can not be fixed via software or special cables.
Keep in mind the HDX is a sensitive device. After flashing a ROM there rarely a need to return to the Safestrap recovery environment. Exceptions:
- flash a newer version of ROM (release release notes carefully)
- make periodic backups of your existing system and data partitions

Correct. Although the goal is to delete all secondary (non-stock) slots there is no benefit to removing the slot that is currently hosting CM11 until you have confirmed the reflash of CM11 to the stock slot. This leaves you with a working ROM should something go wrong.
An 'idle' secondary slot does not present a problem just being there. However, it consumes considerable space and increases the possibility of making a fatal mistake while working in Safestrap recovery. Ultimately the decision is yours whether to keep or discard secondary slots. However, you want your primary slot to be stock. Hope this makes sense.

Hi there. I'm really confused about how to proceed and would appreciate some help.
I have a Kindle Fire HDX 7 (3rd Gen) on which I would like to wipe the Fire OS, and replace it with a working, functional Android ROM. I have some basic competence with installing software, flashing phones, etc., but am by no means an expert. I have both Windows & Linux PCs with which to connect.
A year or so ago I tried to get the tablet working with Google Apps, etc.. I can't remember precisiely what I did (!), but I think I used TWRP, I rolled back the operating system to 4.5.2, turned off the updates, and installed a Google Apps piece of software. The tablet then worked reasonably well, but not great. By that I mean I could web browse, and download and use some apps from the Play Store, but lots of stuff didn't work preoperly. At some time since then, the tablet decided it no longer wanted to install/update from the Play Store, and more of the apps have stopped working. I can still web browse.
TBH, I've got to the point where if I can't completely replace the OS then I think I'm just going to stop using it.
What steps should I take to get a 'proper' ROM working on the tablet?
Thanks very much in advance for any help,
Aaron

There's a good chance you can replace FireOS with CM11 or Nexus, two popular ROMs that are well suited to this device. First order of business is to assess the current status of your device. What version of FireOS is currently installed? It it reasonably stable? Many times laying Google components over FireOS creates other issues that can interfere with components needed to support an alternative rom.

Next step is to allow the device to update to FireOS 4.5.5.1. While you could get by with 4.5.2 the newest rom builds require low level (kernel) components that get installed with 4.5.5.1. Replacing FireOS is the only way to get these pups on an HDX; there is no way to install them separately.
To obtain 4.5.5.1 you need to unblock OTA updates which typically involves renaming a file back to its original ID using a tool such as ES File Explorer. Search for a file starting with 'DeviceSoftwareOTA' which is typically located in /system/priv-app/. It will probably be called 'DeviceSoftwareOTA.bak' or something similar. Rename that to 'DeviceSoftwareOTA.apk', reboot and check for updates. You will loose root if 4.5.5.1 is successfully found/installed but you can get it back fairly easily.
FWiW - There are other methods of blocking OTA updates such as renaming the otacerts.zip file. That approach is less common on this device.

Fantastic! Next step is to root with KingRoot (apk or tethered version). After that the good stuff starts happening. Sorry for piecemealing out details; I find it works better in the absence of an A to Z guide.

Excellent. Next step is to install Safestrap 4.0.1 which provides a pseudo recovery environment that supports the installation of custom roms. It looks a lot like TWRP (but isn't). You can snag the app from here; be sure to select the appropriate format. Once installed launch the app and install Safestrap recovery which is the component that does the heavy lifting.
Important: Once Safestrap recovery is installed never (never!) attempt a 'factory reset' - either from the stock recovery menu or from within FireOS. Doing so will brick the device with no possible recovery.
Now reboot. You'll notice a new screen that has a couple options at the bottom. Select the option that launches Safestrap recovery. Take a look around but don't change anything. When ready return to the home screen and then go into the backup section. Take a backup of your current FireOS installation (selection all partitions). You will want this should you every want to restore you device to it's current configuration. The resulting files will be quite large and should be copied to another device for safe keeping. Exit Safestrap and reboot into FireOS. Tether your device and copy the files to a suitable host. You seem to be familiar with ES File Explorer so should have no problem finding them. Should be in the TWRP directory located within sdcard (or just browse internal storage from the host machine).
Next step is to decide which rom to flash. Two are available/compatible with Safestrap 4.0.1: CM11 and Fire Nexus which are both KitKat based. Both are solid, feature complete and regularly updated with security patches. My daily driver on this device is Nexus as I prefer to build upon a pure Android foundation. That said, CM11 is a fine choice and my preferred rom on secondary devices as it contains a suite of nice UI enhancements minimizing post flash tweaks. FWIW - Lollipop+ roms are not an option as they require an unlocked bootloader which is not possible on your device.
Once you decide upon a rom I'll provide the final set of instructions (really best practices) for installing the rom and related components such as Google Play Services/Store. Feel free to read through the linked threads which contain numerous 'how-to' posts, especially the first couple posts in the rom threads. If all goes well you'll be running a custom rom by this time tomorrow.
Another step complete ...
I downloaded the Safestrap apk from the link contained in the thread, choosing THOR (HDX 7"), installed the app, then installed the recovery software. After a reboot I backed up, and then copied the resultant folder to a PC.
Question: The back up folder is really big (4GB) ... is it okay if I now delete the back up on the tablet? To do this, can I just delete with ESFE?
Duly noted about not doing a factory reset.
After having a read, I think I'm happy to go with the Nexus ROM - keeping things as clean as possible. It sounds like it's very solid with no real issues.
Davey, thanks once again for your precise and excellent help.
Cheers,
Aaron

Super! Final step is to install Nexus. Grab the Thor (nickname for 3rd gen HDX 7) installation zip from here. GAaps and SuperSU are built in so it's the only file you will need. Transfer that to a safe location on your device, preferably in a folder you create directly under sdcard. It is important this file (or it's successors) remain on your device at all times for emergency recovery. Putting it in the suggested location reduces the chance of accidental removal when wiping the (user) data partition. You can also place the folder directly under root (/) but be aware some file managers and tethers restrict access to high level directories.
Important: Unlike TWRP Safestrap v4.0.1 recovery has no ability to communicate with the outside world. Not by tether, wifi, bluetooth, adb, etc. It is fully isolated environment. If your rom becomes unstable (rare...but it does happen) your only recovery is using a previously created backup or a flashable rom image (as discussed above) resident on the device.
Boot into Safestrap recovery. Use the File Manager (under advanced) to confirm the existence/location of the Nexus rom zip. Return to the home screen and then access the wipe menu. Use the slider at the bottom to perform a factory reset which wipes the data, cache and dalvik partitions. Note this is different that a stock 'factory reset' which was discussed in a previous post. Also note it is impossible to wipe the system partition in Safestrap v4 even if selected in the advanced section. I won't get into the reasons; just know it isn't necessary for the upcoming operation.
Return to the home screen and select install. Navigate to the folder containing the Nexus rom, select it and then and then swipe the slider at the bottom to install (flash) the zip which will overwrite FireOS. When complete (assuming no errors) reboot your tablet and select continue to fire up Nexus. First boot make take some time as caches are populated. However, anything over 5 min indicates a problem. Once Nexus starts I assume you know where to go from there. You can safely enable WiFi, register with Google and perform all other requested initialization steps.
A few final footnotes:
- Nexus is pretty bare bones; not even a browser in included in the base build. Head over to the Play Store to grab what you need
- While Google's stock launcher is nice I suggest replacing it with Nova which offers a superior AOSP experience along with robust customization
- Xposed Framework and associated modules offers some excellent additions to this rom if you wish to customize further (advanced topic)
- Once you are confident Nexus is stable you can delete the huge FireOS backup created in an earlier step. Either via ESFE or from Safestrap
You may be aware Safestrap supports multi-boot through the use of user created slots. Unfortunately, they do not work with this device and can lead to unrecoverable bricks. You'll see various cautions in the Safestrap, Nexus and CM threads. Short version: do not create or use secondary slots.
Aaron - Feel free to post any questions/concerns/comments. Someone from the HDX community will likely respond within 24-48 hours. On a personal note it's been awhile since I did a long hand 'step-by-step' which is a refreshing change of pace from the usual bullets. I appreciate your patience as I dusted off various cob webs and hope you make the most out of your newly liberated device.
Nice!
Nexus installed, and I'm using it right now ?
Absolutely superb help Davey. I was totally confused trying to work out how to go from where I was to where am now, and you've completely sorted me out. A massive thanks from me.

Hey Davey,
Thanks for reaching out to my thread and directing me to your conversation here. I followed all your steps and was able to successfully install the Nexus ROM and have everything running smoothly!!! Very happy! I had been hunting for a while to find a step by step instruction like yours!.
Thanks a lot!
P.S. Wasn't sure whether I should post this here or in my own thread but figured you were actively following this
One week on and I've been using my 'new' tablet quite a bit. It's been really solid with no crashes or problems whatsoever. Fantastic. I've now deleted the 4GB back up on the device, freeing up loads of space again.
I've had another good look at the Xposed framework, but frankly I'm so pleased to have the tablet running smoothly I think I'm just going to keep things nice and standard for now.
Davey, thanks (I found the button now!) again for sharing your knowledge, and giving your time and help. Very much appreciated.

Hey Aaron, thanks for the follow-up. If you are happy with native rom/app capabilities there is no need to complicate matters. That said, if you every have a need for additional core functionality Fire Nexus, an AOSP clone, has proven to be an ideal platform for Xposed Framework and associated KitKat modules.
A tip of the hat to @ggow for his outstanding adaptation and ongoing support of this rom that is cornerstone of the post FireOS experience.
Enjoy your rejuvenated HDX!

- what version of FireOS was on the device prior to Nexus? 4.5.5.1 is recommended for the proper binaries
- might try a simple (dirty) reflash of Nexus in case something didn't 'take' on the first attempt (stranger things have happened)

Will try a quick re-flash. ? Thanks!
Update, I have sound over headphones, but not over the speakers... :-S

Suggest you backup your current Nexus build from within Safestrap, then flash the Safestrap compatible version of cm11 to see if the problem persists. Yep, a bit of trial-and-error but not sure how else to diagnose. You could also try the Safestrap compatible build of FireOS (4.5.2; be sure it's the Safestrap build as a standard FireOs build will brick the device). Another option is to flash the Dolby enhancements which use a different suite of binaries. Post back if you need links to any of the above.
Been looking around a lot here to find a solution and I see a few with the same problem but have never come across a solution yet.
I had my Kindle HDX 8.9 Apollo (3rd Gen) running fireOS 4.5.5.1. Installed Kingroot, rooted the device fine. I installed safestrap 4.0.1 B03 and it installed fine, was prompted for root access, allowed it and was able to install recovery. However when I either power off and or within safestrap select reboot to recovery i am stuck at the grey fire loading screen. I have to hold power button kill it, turn it back on go through the safestrap loading screen hit continue or just let it load. Then I get back to FireOS. during boot at the sfestrap screen i hit recovery goes to black screen and eventually have to hold power to kill it and reload again.
I read another post with some similar issues. The issue they had was the system folder was out of room and removing some files cleared up the issue. So i uninstalled safestrap, unrooted and uninstalled king root. Loaded in to the kindle recovery mode and reset to default.
I then proceeded to just use kingroot (root successful) loaded safestrap and rebooted ... same exact issue on freshly restored fire HDX.
I have to be missing something, I have been reading all day about different issues and trying to get past this to install CM11 on the device. Just cant get past this issue to backup and continue the process.
More info:
Safestrap boot screen shows safestrap :disabled
I can provide ADB info if needed.
Any suggestions?

A stock factory reset (misnomer) does not touch the system partition; it only flushes the data partition. While I am not sure what is causing the problem with Safestrap recovery insufficient space in the system partition would certainly do it. Once rooted you can use ES File Explorer or similar tool to review the contents and identify potential candidates for removal. IMPORTANT: Don't delete anything without verifying the file is safe to remove. Also don't mess with permissions or try to edit build.prop. As you are probably aware even the slightest abnormally in the system partition can cause FireOS not to boot which is usually fatal on this device.

Ok thanks Davey I will take a look at the system partition and clean anything up I can. Maybe that is the problem I am still fighting with just a space issue. I will give it a try and report back.

Im looking through system using es file explorer any suggestions on what to dump? Is the system "partition" just items under the system folder?
Just trying to be careful on what i get rid of. Is there a list of items published in a stock Fire HDX by chance? Would be nice to have something to look at and compare.

No standard list of folders/files that I am aware of.
Let's verify whether space is really an issue. Recall I'm not sure what is causing the problem w/Safestrap although it has been reported before.
Grab the following app that will help you visualize space in the system partition (apkmirror is a well regarded repository for Android apps):
http://www.apkmirror.com/apk/ivan-volosyuk/diskusage/
Check free space in under /system mount point. Tap and pinch-zoom as needed. If > 100MB you should be fine. Don't delete anything just yet. Just looking ...

Man this app is awesome! I have included some screenshots of the /system mount point ... there is some issues here for sure. All them teeth and no toothbrush .. I have attached a few screenshots to show what the system mount point looks like. I drilled into a few of the more expensive folders to show more detail. Let me know if you can see them ok, or need to drill in deeper to them.

Good stuff; was able to view the images fine. You don't need a ton of free space for Safestrap Recovery. Suggest deleting a couple benign Amazon apks in the priv-app folder such as weather and calculator. Don't go crazy or clobber apks that don't have clear function. Again, you just need enough space for Safestrap. The rest of the clutter in /system will get flushed with the installation of a custom rom.

OK few things. I was able to free up 110 MB of /system space these are the apk's i used titanium to backup and then uninstalled:
Weather
Audible
Contacts
Calculator
Maps
Kindle Tutorial
Calendar
Contacts
Goodreads
Nuance Dictation
And the Kindle Office App
I rebooted and the fire came up (shew)
I now have 110 MB free. So I rebooted from safestrap into recovery and same got the grey fire logo and seemed to lock up. So held power rebooted got the safestrap screen (Still showed disabled) Back in fireOS.
I unstalled recovery in safestrap
uninstalled Safestrap
went in to ADB and reinstalled safestrap
Installed recovery inside safestrap
rebooted to recovery
got the grey fire again and presto there is the recovery screen.
So I think I am ready to make a backup and find that awesome walk - through you did and follow it along.
Pretty stoked!! Thanks for the hand with this, I am sure I am just beginning the fun!!
Any suggestions on the ROM?

As you know your choices are limited to HDX Nexus and CM-11. I use both on different devices. Both adaptations are stable KitKat builds with proven track records. I have a slight preference for Nexus on this device as makes best use of hardware resources (IMHO) and has the greatest compatibility with Xposed modules like GravityBox which significantly extends the already excellent UI. Toss in Nova, Google Play Services and Greenify and you have a nice device that rivals Lollipop/Marshmallow equivalents.
Be sure to review the HDX Nexus OP and Safestrap v4 best practices before proceeding. Highlights:
- no need to flash GAaps or SuperSU with this rom; both are built-in
- be sure to backup your current FireOS build from within Safestrap and store the archive on another device
- be sure to perform a factory reset (wipe) from WITHIN Safestrap prior to flashing a *new* rom
- you cannot communicate with the outside world from with Safestrap; all files must be copied to device in advance
- Safestrap is a capable but sensitive environment for hosting custom roms; it is NOT a full recovery, hence ...
- IMPORTANT: never perform a factory reset from the stock recovery menu with Safestrap v4 installed (instant brick)
- IMPORTANT: always keep a copy of the Nexus installation zip on your device for emergency recovery
- IMPORTANT: do not create/use secondary slots; only flash roms to the STOCK slot (overwrites FireOS)
Any questions bounce back. Several respected contributors monitor these forums and more than happy to assist as needed (and keep you out of deep doo-doo).
So, I've been wanting the Galaxy Tab S7+ for months. But I haven't had the money for it until now (yeah, you guesses it, stimulus payment). But I'm still on the fence about buying it. I know bootloader unlock, TWRP and Magisk root is available for this tab. But I don't want to be limited to just running stock-based ROM's. My plan is to flash a Project Treble-based firmware like Phh Treble, Resurrection Remix.
The questions I'd like to ask are:
1. This tab appears to be Treble compatible, it is listed on the Treble device compatibility page as working. But I would like to hear from an actual owner of this device that has successfully booted and ran a Treble/GSI ROM
2. The partition layout is ARM64 A/B and system-as-root?
3. Besides unlocking bootloader and flashing TWRP, are there any other special considerations I would need to know about?
Without this info, I won't buy, and Google doesn't always produce solid answers. I would like to become an active developer for this device as well, but I need compelling reasons to buy it, besides just great hardware, the latest Android 10/11, that kind of thing....the superficial stuff.
I could just buy now and test when I get it, Amazon has a 30 day return policy. But I don't think they will accept a tablet return if the warranty has been voided by the user. So this really isnt an option.

1. At present, AOSP v304 GSI can be booted, but no Magisk yet. This is if you have Android 11 stock FW. The situation with GSI might be different (probably better) with Android 10 stock FW, but I can no longer test this, as the latest BUC1 build blocked the downgrade path. You can still downgrade to Android 10 (up to ATK3) if you're on build BUBB or below.
2. This device uses a Super partition (also called dynamic partitions) for system, vendor, etc.. Because of this, flashing GSI is no longer trivial. You can try using this tool to flash a GSI from TWRP.
3. Currently TWRP cannot access /data if it's encrypted. You need to flash Multi-Disabler to disable encryption (which requires formatting /data) if you want TWRP to access it. Also, while Magisk works on stock FW, be careful when debloating as some Samsung components are not happy with certain components removed and would cause trouble.

Thanks for the info, I honestly didn't think I would ever get an answer.
You say the AOSP GSI can be booted. But do you speak from experience? Or just from what others have said?
The part about BUC1 blocking the downgrade path is useful, I'll keep that in mind before installing any OTAs or flashing firmware with Odin. Yes, I do imagine that Magisk is more compatible with AOSP based ROMs vs stock, that has always been my experience on other devices.
I already did some reading, I'm aware of the super partition thing. I know I'll have to unpack and repack the super.img, replacing the system.img with a Treble one.
I'm also aware of the file based encryption that TWRP can't read, I don't encrypt my devices, and plan to disable it.
I know all about debloating troubles, I've done it on numerous devices, important stuff can definitely break if you're not careful.
I'm wondering if you can answer a few more questions:
1. Are you rooted?
2. Can the system partition be remounted as read/write from within Android on stock firmware? I have heard cases where the dynamic partitions can prevent this, but supposedly it's not usually an issue on custom ROMs, just stock. I ask because I will be debloating, but if remounting system isnt possible, then I'll need to rely on Magisk for systemless debloating. Or just remain unrooted and debloat with ADB package disable commands (this doesn't really delete anything, and works without root).
3. If you are running Magisk,can you upload a screenshot of the main screen? I just want to see the A/B and SAR values.
4. Can you install the free version of Treble Check from Play Store, and post screenshots of the main info screen?
5. Is it possible to moves apps to SD without enabling adoptable storage (on stock, I know custom AOSP firmwares will require AS, or a root app like Apps2SD and a 2nd partition on SD.
I'm hoping to hear from at least another confirming user before I make a buying decision, spending $1k+ on a high end tablet is a big deal.
And if I do buy, I am serious about becoming a developer.

I actually booted it myself and kept a backup of it so I can test it a bit further if needed. With TWRP and appropriate backups it's not difficult to switch back and forth.
Since Magisk can't work with Android 11 vendor at the moment, and that recent GSI builds are not certified for some reasons (which blocks Google login), my current use of GSI is still a bit limited, so I'm mostly still doing stuffs on stock.
As for other questions:
1. I'm rooted on stock ROM with Magisk (it works there). Magisk does not work on GSI with Android 11 vendor at the moment.
2. I haven't tried mounting system r/w from within Android, but TWRP certainly could mount it r/w, as Multi-Disabler needs to modify stuffs there. For GSI, you need to use vndklite variants in order to be able to mount system r/w.
Honestly, this is my first Samsung Android device and is also my first device with a super partition, so I still have a lot to learn...
EDIT: I'm using a Galaxy Tab S7+ 5G variant. I think for Wi-Fi variant most things should be similar... but I'm not really sure.

I am using the WIFI variant (SM-T870) on the latest stock release (T870XXU2BUC6) with root and Magisk 22.1 running just fine. Root was accomplished by flashing a Magisk modified boot image with Odin found here https://forum.xda-developers.com/t/...-updated-3-29-21.4159291/page-2#post-84843377 on this thread. I used Titanium Backup to debloat and have had no issues at all. The performance is great and the stability sound. I would suspect that a similar arrangement could accomplished on the other versions of the tablet but cannot speak from experience. Personally I have never had much luck flashing Project Treble GSIs on any of my devices. They tend to be very unstable and iffy at best and I always wind up returning to stock or another custom ROM choice.
