Hello everyone. I am new to the world of android, but I'm a quick enough learner. Here is my specific problem:
I have an AT&T Atrix 4g. It is currently superuser rooted. It is currently running Android ROM 2.3.4.
Shortly after rooting the device, I downloaded ROM Manager and successfully installed through the application Clockwork Recovery. I tried to select the option to back up the current ROM (the stock android) on my SD card.. however, during the load screen, I got an error message stating
"Failed to boot 2
Starting RSD protocol support"
So doing some research, I came upon the conclusion that the reason I can't backup or really do anything with ROMs is that I needed an unlocked bootloader.
I went to Atrix4ghacks and followed the instructions on how to unlock bootloader and install permanent recovery.
This is the critical part: When I entered into the command prompt "fastboot oem unlock", instead of proceeding normally I got the return message:
"OEM unlock is not implemented"
Again, did a google search and read that Android 2.3.4 on Atrix 4g does NOT allow unlocked bootloaders.
So, the questions that I have that result from this are:
1.) Can someone here confirm that, in fact, I am unable to unlock the bootloader on my phone?
2.) If so, is there a viable workaround that is both reasonably safe and not overly complicated? Please note that I have no backup in case something goes wrong, leading me to
3.) Is there a way to backup my stock 2.3.4 ROM without an unlocked bootloader?
4.) Can I revert safely to an older android version that supports unlocked bootloaders?
5.) Can you actually install new ROMs without an unlocked bootloader?
6.) Am I totally screwed?
HUGE THANKS to anyone who actually bothered reading this, and even more thanks to anyone who can answer/point me in the right direction. Much appreciated!!!

Thanks a ton for that link. I'm sorry to ask once again, but I'm very wary of possibly bricking my phone... so I must ask: Is your solution possible with 2.3.4? Or will the phone softbrick?
If you did the Over The Air (OTA) update to 2.3.4 then yes your phone will softbrick after flashing the bootloader. Re-enter fastboot and issue the unlock commands and everything will be fine when you reboot.
I recently got my TF201 and soon as I got it home and turned on the WiFi, it updated. I put "Android System Info" app on it so I can see most of the system info, and I've ran the Unlock tool from Asus and have the Bootloader unlocked.
So my question now is, since when i boot the tablet, the top left says "Bootloader unlocked", can I flash CWM and then a rom, or do i still need to get root access and can I?

With your bootloader unlocked, you can install CWM without root access. See my response here (http://forum.xda-developers.com/showthread.php?t=1585046). On the link in that thread, use the "non-rooted" method (fastboot) to flash CWM. Then you can install your ROM.
Confirmed, this is what I had to do.
Unlock, flash cwm (TOUCH VER. )
Then flashed Virtuolous newest rom.
It would be nice for a guide, or a tuturial for someone on a locked, and stock .21 rom for the prime

A guide/tutorial for a "locked & stock .21" is impossible since you need to unlock your bootloader.
And there are plenty of guides/tutorials on how to flash CWM onto your unlocked Prime.

It's quite possible...someone would just need to run a step by step including the unlock apk then move onto the steps of fastboot load of CWM. I agree that all the tutorials are there, but it requires a little hunting to piece them together.
This is where I went to unlock the Bootloader:
http://transformerprimeroot.com/tra...ow-to-unlock-bootloader-on-transformer-prime/
had to visit the page on the tablet cuz it wouldn't download otherwise
The question though, is once I install CWM and a ROM, do I have Root access, or can I only flash Pre-rooted roms?

Well yes, sort of. There are guides on how to unlock the Prime. Guides on how to flash CWM. And guides how to flash a custom ROM.
But the way the question was worded, it was how to flash to an unlocked, unrooted .21 Prime. Which you can't do. Flashing pre-supposes that you've unlocked it.

You have root access if the ROM you're installing is pre-rooted. If you install a ROM that is not pre-rooted you do not have root access. Whether or not you can root that ROM is another matter.
Why would you install a custom ROM not pre-rooted?
So call me blonde, dumb, or just flame me, but im sleep deprived on a daily basis so I'll ask a dumb question again.
Since I have my bootloader unlocked, all I need to do is flash the Touch CWM, and then a pre-rooted rom and I'm all set. No needing to gain straight up root access right here right now like i had to do with my EVO 4G just to be able to get into the Bootloader and put in the recovery

Correct. Just make sure to follow instructions to the letter. You'll need to flash the CWM using fastboot seeing as you do not have root.
Im sorry if this has been answered in other threads im simply trying to help a friend out with rooting and possibly unlocking the boot loader? Can someone point me in the rite direction? It would be most appreciated
I would check the Verizon LG G3 forums where there are many instances of your questions having been already thoroughly answered.
What you will find is that you must be on v10b firmware, which you can downgrade to using either the .kdz or the .TOT method, then you can root v10b (only) with StumpRoot, or ioRoot, or PurpleDrake, before the phone updates back to v12b. With SuperSu in survival mode root can be retained through either of the current OTA updates (which provide very little enhancement beyond patching root exploits), so far, and with root you can install a specially modified TWRP recovery which will allow the flashing of unsigned kernels and roms.
There. You are on your own from hete on.

use flashify to install the bumped version of twrp (get it from the original development section). Worked like a charm. Plenty of bumped roms to grab in the dev section.

There is no unlocking of the bootloader. Bumping doesn't unlock the bootloader. However, it fools the phone into allowing the flashing of custom ROMs and kernels without unlocking the bootloader. Basically, the phone "believes" that whatever is being flashed (via TWRP) is acceptable and allows the image to pass the "security check" that is done when flashing. It's the same thing as IF the bootloader were unlocked, but in reality, it isn't unlocked. It's a security exploit, kind of like rooting this phone is a security exploit.
However, a quick OTA patch from Verizon or LG could make either or both no longer work. In fact, some OTAs have fixed the root exploit on some models, so you have to flash back to a previous version to root.
You have to root first, then you can flash TWRP.
As stated, there are plenty of FAQs in the general G3 section that help explain all of this.
OK thanks guys. Um just used to seeing a sticky on root under original android development I have no idea what firm ware he's running ik how restrictive big red can be at&t is no better but that's why when they offered a nexus I went and grabbed it

Due to a bug, I have been able to get root on my OnePlus 2 running Oxygen 2.1.1 without a wipe.
DISCLAIMER: This may not give you root on yours, and obviously it may also loose you data, so don't do it unless you know you can cope with that. YMMV, but I've documented here for posterity how to do it!
I had unlocked the bootloader previously, because my device is an import, so it is possible, though unlikely that it simply doesn't wipe on an unlock after re-lock (OTA locks bootloader).
The basic steps are :
Encrypt your device
Unlock the bootloader (this won't wipe because of encryption!)
Boot TWRP
use adb to push SuperSu to your device and then flash it
Then you will have root. Step by step instructions below.
Note that TWRP currently doesn't support encryption on our devices, so you'll have to use something other than that to back up your data if you want to use a custom rom. This simply gives you rooted stock Oxygen.
After rooting :
Code:
$ adb shell
[email protected]:/ $ su
[email protected]:/ # id
uid=0(root) gid=0(root) context=u:r:init:s0
Step 1: Encrypt your device.
This is irritating but fairly simple. You have to have fully charged your device AND keep it plugged in, and it takes ~50 minutes to complete. It's the standard android encryption, so follow any guide for this, such as https://support.google.com/nexus/answer/2844831?hl=en-GB
Step 2: Unlock the bootloader.
Again, this is well documented - here's a guide : http://forum.xda-developers.com/oneplus-2/general/guides-how-to-guides-beginners-t3146568 - The important thing is that if you're encrypted, this does not do a wipe, in my experience.
Step 3: Boot TWRP
Download TWRP from https://dl.twrp.me/oneplus2/ and save it somewhere you can find it later - I'm going to assume you're on linux and have saved it in ~/Downloads/TWRP.img
Reboot into bootloader mode (Power and Volume up) and start TWRP by issuing the following command (substituting your path to twrp) :
Code:
~$ fastboot boot Downloads/twrp-2.8.7.0-oneplus2.img
Step 4: Root it!
This is a bit tricky because once you're encrypted you can't access the SDCard, so you need a bit of magic to flash the zip.
First, do the swipe to enable modifications, then in mount, tick the /system option.
Then, on your PC, download SuperSU's .zip update from https://download.chainfire.eu/696/supersu/ (similar to above, assuming same download location) and use adb push to put it on the device in /tmp :
Code:
adb push Downloads/UPDATE-SuperSU-v2.46.zip /tmp/su.zip
Next, from the main TWRP menu, select Install. Navigate up (you start in sdcard that is empty) and into tmp, then select the su.zip file in there.
Swipe to install the zip - TWRP will complain because it can't access /data, but handily, /data is not needed to root!
Select Reboot, and viola, you have SuperSU and root! Now you can install Titanium Backup and back up your device.
Cool, perhaps renaming the title like "Unlock and root without wiping" could make more sense?

OTAs don't re-lock the bootloader though...
If you've unlocked it previously, it'll stay unlocked unless you boot into fastboot mode and do a "fastboot oem lock".

Not true I'm afraid. The OP2 OTA to 2.1.0 did indeed relock the bootloader. I know this because I would never want to lock the bootloader, and I'm on a Chinese OP2 which came with masses of spyware, so to install clean 2.0.1 I had to unlock the bootloader originally (they managed to get the spyware into the recovery image!). Anyway, it's irrelevant to this thread how the bootloader got relocked, I just documented this fiddly way of getting an unlocked bootloader with root on a locked OP2.

Maybe my post should have said "OTAs don't re-lock the bootloader since 2.1.0"

Confirmed on 2.2.0 or still on 2.1.X?
Can confirm, this still works on 2.2.0.
i didnt try this tutorial, but when i rooted my phone, my data didnt got wiped either.
will root on 6p running android n dev preview wipe phone?
Any chance this works also on 1+1? I'm desperate for a way to root without unlocking so I can install titanium/nandroid and do a full proper backup before wiping clean (battery life is utter crap). Running latest stock 6.01 COS. Never unlocked, never wiped since 15R.
Thanks!
anyone tried this on OOS 3 ?
Yeah, bump!
Now my OP2 is on Oxygen 3.0.2, and Android 6.0.1 - stock.
My phone had always been (bootloader) unlocked and rooted, since the day after I got it.
But to get the new OTA update to Oxygen 3, I tried a different method this time, where some people said you can do a temporary un-root, get the stock OTA update, and then re-root.
I followed their instructions, but I can't re-root as simple and easy as they said.
Before the process, I didn't do a nandroid backup because my sdcard doesn't have room :-|
So now I need to re-root without losing data.
And I've tried helium before, many times, and it never works for me.
Any other ideas, or has anyone tried this encryption trick yet with Oxygen 3?
Thanks!
tried it on oos 3.1:
everything worked until a bootloop at the last restart.
also twrp asked me to unlock the phone, i did that.
what to do now?
Did anyone ever have any success with this approach on 3.1?

I've just bought V30 and would like to root it. Preferably with Magisk.
Every guide I found requires to unlock bootloader. This is one step too far for me. Is there a way to root V30 without unlocking it's bootloader?

NO.
Which variant did you buy?
With some, it's simply flashing a simple code via fastboot flash commands. On others you first have to convert to a variant which has fastboot flash commands, so you can flash that code. If you tell us which variant you bought, you will know if you have extra steps or not...
For all V30/V30+/V30S (except T-mobile H932) for bootloader unlock and root, you need to:
have fastboot flash commands
be on specific Oreo firmware
use the "fake" bootloader unlock code
install TWRP and flash Magisk (OK technically there is a way to root without installing TWRP, but it's easier with TWRP)
WTF V30/V30+/V30S Bootloader Unlock and Root
Thank you for your reply. I've bought European H930. Unbranded.
Android 8.0.0. Build: OPR1.170623.026. SW: V20d-EUR-XX. Security patch: 1.03.2018.
I don't want to loose my warranty, DRM protected stuff playback capability, etc.
These warnings from LG bootloader unlock website worry me and make me extra cautious. I have to be 100% sure none of the things will happen:
"When unlocking the bootloader, applications which require a trusted execution environment (TEE) to operate will not work properly because after unlocking the bootloader the device will no longer be trusted.
Unlocking the bootloader will also affect the DRM protection of your device, therefore some applications which require DRM protection may not work anymore or block certain functions due to this untrusted state.
Common examples for affected applications are services which offer download/streaming of paid multimedia content like music and movies or services offering mobile payment."
Is there at least reliable app+data migration utility to move my apps with data from an old (Marshmallow) phone to this new one? LG Mobile Switch didn't manage to migrate apps' data.

LG also throws a scary bootloader unlock warning in your face.
LG's "warning" is to keep you from rooting your phone. If you've rooted phones before, its no different.
Magisk hides root, so all apps work.
Anyone who's rooted their V30 can tell you how it is. The threads here are very active!
But it's your decision.
Is it possible to lock back the bootloader at the end of the process?

At the end of what process? Rooting? You don't seem to understand, you have to unlock the bootloader to install TWRP. You have to install TWRP to flash Magisk. OK, technically there is a way to root without TWRP (by installing a rooted kernel), but you still need bootloader unlock.
You seem hung up on bootloader unlock when it's REALLY root that LG is trying to prevent. They really couldn't care less about bootloader unlock, they are focusing on that to prevent you from rooting your phone. Because once you unlock your bootloader you are one step away from root...
Yeah, you can lock the bootloader back if you no longer want root.
Most phones require bootloader unlock to root -- Motorola, Pixel, LG, ZTE, OnePlus.

I'm sorry, what is the DATE of the security patch? May, July, September? If pre-July, you are good to go. You just flash a simple code with fastboot. If July or later, you would need to temporarily downloader to pre-July 2018 firmware.

Yes. I was wondering if it is possible to lock back the bootloader once the phone is rooted, TWRP, Magisk are there. The question behind it is if having unlocked bootloader doesn't unnecessarily increase security risk (of course the main risk is to have rooted phone, and I accept it).

Good news. Suppose I would unroot and lock back the bootloader, then send the phone to warranty service. Is it possible for the service to discover the phone was rooted and reject my warranty claim?

So far I've rooted every phone without unlocking bootloader. It was harder, but in some cases possible (Xperia Z2, Xperia V, Motorola Defy).

It's March.
I am not familiar with Magisk. Is it safer from the security point of view than classic roots with SuperSu+BusyBox?
Correct me if I am wrong, but unlocking bootloader means gaining write access to boot partition. TWRP needs to be stored on it. Kernel is also there. And where is Magisk stored?
