Hey Guys,
as far as i could find out so far, you use TWRP to flash a Custom Rom from the Tablets Recovery Mode, this requires a rooted device, and to do this you flash a prerooted rom somehow, which includes TWRP already, which you then use to flash the rom you actually want on your device.
Another possibility was to flash a Kernel (with TWRP?) to get the same results...
Now I absolutely can´t find a tutorial for dummies, to do that, or find the required files.
After i found it kinda complicated to unlock the bootloader, since most of the tutorials didn´t even mention you need advanced mode and a special Google USB Driver from Sony´s Developer Page, to even get that working, i would really appreciate if someone could give me a step by step with links.
If a tutorial exists, pls give me a link as well, cause i looked the whole day yesterday, and found jack.
cheers
yes, you need to do all that. i just went through this yesterday and used this tutorial:
https://forum.xda-developers.com/showthread.php?t=2747676
once you are unlocked, follow the instructions for your rom, usually to flash the boot and recovery images with fastboot. two things to watch out for though, if you are using an oreo rom make sure your twrp version is 3.2 or better, secondly, if twrp give an error where it cant mount the partitions to wipe them use the change format option under wipe/advance to change to ext4 (which essentially re-formats the partition) and you should be good to flash the rom after that.
here is another tutorial to help get adb, fastboot, and the drivers up and going:
https://forum.xda-developers.com/showthread.php?t=2588979
answer yes to everything, i can't remember if i loaded in sony specific driver on top of that or not.
goodluck!

Hi, everyone, I just got my z3 tablet and I am in love with it except i don't like the interface. So i decide to root my tablet without unlocking the bolted and I did made it and i did install TWRP. I have a question, since I have TWRP is it possible for me to install cm 12 rom or I need to have a unlock boot loader in order to install it?
Sorry for my bad english and thank you for answering my questions.

You need to unlock to flash a custom kernel which would be needed by the cm12 to run. So first.
1.Backup drm keys
2.Unlock BL
3. Flash CM kernel via fastboot
4. Flash CM Rom via recovery.

I just bought a Z3 tablet compact, which should be here at the end of next week. I haven’t found a tutorial which includes all steps to get from the standard rom to CM12. Did I miss any steps or does the following steps include everything?
Root tablet on the original Sony rom
Backup TA partition (I guess that's where the DRM keys are?)
Unlock bootloader
Flash a recovery (any recommendations?) I found this tutorial, but I only need one recovery and I don’t want to flash that zip every time I install a new rom.
Flash CM12. Are there any kernels beside that one included in the CM12 zips?

I guess you should just flash the kernel via fastboot after unlocking the bootloader, that would eliminate the need to flash a recovery. It's hitting 2 birds and one stone and besides CM uses a different kernel than stock so later you would really need to flash kernel.

Thanks for your reply. The whole flashing procedure is a lot more complicated than on my S3, so I have a follow-up question.
Should I just backup the TA partition, unlock the tablet, flash this kernel which should give me root and TWRP and then flash another recovery and CM12?
I found this recovery which is only semi-permanent, because you have to flash it before you upgrade/install a new CM12 version. It’s not big deal tbh, but is there a permanent recovery, which I only have to install once.
I'm also curious about this.
Right now, I'm trying to download the Flashtool program from Sony, but apparently, you need to "register" for it. Where did you guys download your Flashtool from?

Correct, make sure the kernel is compatible with CM

The whole procedure is really frustrating, maybe someone can help me here.
I did a backup of the TA partition and unlocked the bootloader. I tried flashing the boot.img from the cm.zip, but I have no idea how to flash the rom via the cm-recovery.
Flashing the advanced kernel to get TWRP wasn’t successful as well. I tried the fastboot mode of the Flashtool and flashed the kernel, but nothing changed.
Can someone post a brief guide with the next steps to get CM12 running (with cmd commands pls)?
EDIT: I just tried to use “adb sideload” in the CM recover, but “adb devices” doesn’t show the tablet .
EDIT2: EDIT: Seems like I got it to work after all. The DualRecover Installer worked, even without SuperSU installed.

I ran into the same problem usin the cm12 nightlies from 27th march 2015:
Sideloading would not work because the tablet is not recognized by the computer. I tried with Windows 7 and gentoo Linux.
Installing from the sd-card in recovery mode was also not possible due to a error of missing "/misc".
I solved the problem by manually choosing the driver in Windows 7. I booted the tablet into recovery. Choose update using adb as detailed in this post:
http://forum.xda-developers.com/z3-...t/root-root-locked-bootloader-sgp621-t3013534
Then I found the device in the windows device manager. Here I manually choose the adb driver that I installed earlier from the flashtool package. After that the device was correctly recognized by Windows and I could Sideloade the cm12 image.
Recently I attempted to root my Nexus 9 (running 6.0.1, latest OTA update) using this guide: phandroid.com/2014/11/05/how-to-root-nexus-9
It didn't go so well and I ended up in a bootloop after completing the steps. I managed to resolve this by following the steps on the Google Developer Factory Images page using the latest Nexus 9 (Wi-Fi only) image (I did not re-lock the bootloader, however).
After this, the device booted fine, however it is not rooted (apps cannot get root access and rootchecker and supersu both state that it is not rooted). I would appreciate some help here, as I am not sure where I went wrong (for example does flashing the factory image de-root?) or how to gain root from here. Most of the guides I have seen are for android 5.0, and I am not sure if the software used/linked is still compatible. I am not planning on moving away from stock android on this device, so a custom recovery is not necessary for me, and most guides include installing CWM or TWRP (I'm not against this, I just figured it's not necessary.)
If anyone could link any guides that are still valid (or tell me what to do) it would be much appreciated!
That guide is way out of date and links you to wrong files. Flashing factory images will remove root.
Get latest TWRP image .
Boot your device to bootloader mode. Attach to PC issue this comand "fastboot boot <name of twrp.img>".
Have latest supersu.zip on your device before hand. Use the Temporarily booted TWRP to install that zip.

Thanks! I've just gotten around to following your instructions, and that was totally painless. Much simpler and faster than anything I found elsewhere, too (Guess all the guides I found were hopelessly outdated).
Will this method work for all current devices (assuming I have the correct TWRP, of course)?
@Sithon
Should work with most nexus devices.
Other devices may have locked bootloaders and need different methods to root. Check the device forum.
Hi all,
So i am no developer and never will be but I do like to understand what i am doing, why i am doing it when I see instructions on the internet. I have just been flashing an unofficial custom LineageOS 15.1 ROM on my Samsung Galaxy A3 2017 and suffice it to say that took hours of working out what i need and I am still not entirely sure I was hoping someone could explain it in simple plain english?
I have seen videos on how to create a custom ROM based on ASOP and read a guide about including hardware drivers before you compile. I guess if the vendor (ex. Samsung) they make their drivers for the hardware open source and you can get them that is a big plus, but i guess those drivers is not everything, i can imagine bootloaders, recovery, root etc etc also plays a role?
So when i wanted to flash my Samsung Galaxy A3 (2017) i go on to XDA and look for my phone and scroll through the forum. Only to find out not that many roms for that model. probaly down to popularity
Anyway i was instantly overwhelmed regarding unlocking the OEM bootloader, installing TWRP recovery and then root the device with SuperSu, installing ODIN etc etc.
So i wonder could anyone explain all this in much simpler steps? I mean the process i read was basically this:
Enable developer options
enable OEM unlock
Install TWRP using ODIN but i also needed something named RMM-State_Bypass.zip ?? not sure what this is this needed to go on SDCARD
reboot phone into download mode and using ODIN to flash TWRP recovery
Boot into TWRP recovery and flash that RMM-State Bypass file
Then i had to root using SuperSU (is Magisk not preferred now?). but for this i was asked to download SuperSU and a "no-verify-opt-encrypt-6.0" file. which I am not sure what is. then put them on SDCARD and boot into TWRP recovery
Then i had to format data reboot into recovery and then flash RMM_State again from above, then flash that "no-verify-opt-encrypt-6.0" file followed by flashing the SuperSU zip file.
Now reboot device and I was root.
Now what the heck did i just do with those files and why is root needed when i shortly after had to copy LineageOS 15.1 to the SD card. boot into recovery and wipe "system, data, dalvik, cache" and then flash custom ROM followed by GAPPS.
When you wipe System, data, cache and dalvik. does that not undo the root we did above? I do not understand
I guess those no-opt-verify file and RMM State bypass probably has something to do with bypassing some Samsung stuff on the device. but really i would love for someone to take the time to write something up in plain simple english, or if this has already been done point to it so that i can read it.
Probably completely crazy but i would love to do a personal CUSTOM ROM for Samgung Galaxy A3 (2017) based on AOSP with GAPPS and thats it. obviously drivers from Samsung so the hardware works. I am fairly certain that following guides on the internet i could create my custom rom, provided that i have the samsung drivers. but i have no idea really what i am doing and why in order to install TWRP and root etc
Feel free to PM me if you feel like that instead
anddd use magisk.
I just bought a Nuu R1 Rugged Phone. It has Oreo 8.1.0 on it.
It is an "unlocked" phone. But I don't know if unlocked refers to the phone carrier or to the boot loader. (I'm thinking phone carrier.)
The last I rooted my tablets was Android 5, which required using a custom script that a dev here wrote that temporarily ran CW via fast boot.
I would like to root my R1. I hear now that Magisk is the way to go. (Instead of SU.)
Most every Guide says that I have to have TWRP installed before installing Magisk. But there's no TWRP for the R1. And I am incapable of compiling my own.
I learned, from Nuu Tech Support, that I can get into the phone's Recovery mode with some hidden button pushes. Here's a screen shot:
My first question is, could I simply install Magisk by selecting "Update from SD card"?
If it's not that easy, then, second: I can also get to a fastboot screen. (Not shown here.) Could I install Magisk from ADB on my computer?
I suppose a third question: Is there a version of TWRP that's compatible with this phone? And if so, how do I find it? It would be nice to have a Nandroid backup.
I am willing to show various screens that come up from various button pushes if that would help a dev here.
More data for TWRP'ing
So, I see that one needs an image of the OEM ROM to compile TWRP. I found two sites on the web that claim to have the ROM. (Before the R1 was officially released.) Sounds sketchy. Will try to get an image from Tech Support.
In the meantime, I found that the bootloader can be unlocked (or allowed to be unlocked) via a setting under Developer Options.
I contacted Nuu Mobile Support and they were kind to send me the MediaTek USB drivers for the R1.
It was a two step process to get the driver installed for ADB. But now I have access to the R1 via ADB.
I read here on the forums that I can boot TWRP via fastboot, and not risk ruining/corrupting the R1's Recovery Partition.
Anyone know of a TWRP model version that's close enough to work on the R1? (I presume a TWRP for another MediaTek device might work?)
I would hate to try KingRoot to get root.
I found a website called unofficialtwrp.com. It has a TWRP for the MediaTek 6739, running Oreo 8.1, with 16/2 GB. That's exactly what the Nuu Mobile R1 has.
So, hopeful that this would allow me to root my R1, I tried it. (Short version: Didn't work.)
I already had ADB installed and could talk to my R1 via ADB.
But once the R1 had booted into fastboot mode via ADB, I got a message from fastbood devices that it was "waiting."
I learned that that message means that I didn't have drivers for fastboot.
I ended up installing a fresh version of Win8.1 and using the Windows' updater to find the needed drivers. I had to have the R1 plugged in to the USB in fastboot mode for this to work. After that, I could talk to the device via the fastboot command.
So I unlocked the boot loader (which wiped my data - not every Guide warns you about that) and I did "fastboot boot recovery.img."
I got the message that the recovery file had transferred. After abotu 15 seconds, the phone rebooted. But no TWRP.
Rats.
I didn't want to try the fastboot flash command in case this unoffiical twrp from an unofficial site bricked my phone. If I understand things correctly, booting in fastboot to the recovery.img should give me a temporary instance of TWRP.
Presumably, after copying Magisk into memory, I would be able to get root that way.

Whoa you have been busy you must've heard XDA helps those who help themselves.. :highfive:
I just dropped by to say, 1st rule of modding is taking a pristine stock backup..
For MTK devices, there is a tool called SP Flash Tools, a quick search will help you take a full backup using this tool.
Afterward, you can even try using SP Flash Tools to flash a Magisk patched boot image to your device for ROOT!
Hope this helps!
Thanks. I did see SP Flash Tools mentioned and I did take a look at it. While I've rooted before, I'm trying to get my head around a Scatter File.
Everything I've read so far - well, almost everything - says that I need TWRP to get Magisk installed. But if you think it can be done via SP Flash Tools, I'll start playing with it.
Root nuu r1
Did u ever manage to figure out how to do this & get TWRP to install? :fingers-crossed:
No, I haven't had time to play with rooting lately. I still would like to root it tho.
Anyone know how to root the nuu phones?

Unlock the bootloader first, this step will factory reset your phone https://romprovider.com/unlock-bootloader-android/
On your PC:
1. Install Fastboot driver
2. Install MediaTek_Preloader_USB_VCOM_Drivers_Setup_Signed
3. Extract platform-tools
4. On your phone, Enable Developer Options, USB debugging and OEM Unlocking
5. Unlock bootloader (this step will factory reset your phone): Phone in fastboot mode, open command prompt on PC > fastboot devices > fastboot flashing unlock. Note this will cause the phone to show the "Orange State" warning on boot up. You can ignore this or remove it later.
(If device is unauthorised in ADB or Fastboot, go to Developer Options on phone, revoke USB debugging authorisation, disable then enable USB debugging. You should now get an authorisation confirmation dialogue when you try to connect with ADB/Fastboot. If not, type "adb kill-server", then "adb devices" or "adb start-server" in the command prompt).
6. Place boot.img on phone with USB file transfer (either from stock ROM, or read from phone using SP_Flash_Tool_v5.1924_Win) and patch it with Magisk v5.2. NO need to patch vbmeta.img
7. Transfer patched boot.img back to PC
8. Flash the patched boot.img to phone either with SP Flash Tool or Fastboot command in ADB (fastboot flash boot boot.img). Take care here, make sure it's the right image going to the right location and that ALL other files are de-selected, especially the preloader file, always de-select this when flashing any firmware unless you know what you're doing!
Phone is now rooted.

It is possible that in the future, developers may create custom ROMs and TWRP recoveries for the device, especially if it becomes popular among the Android community.
If a custom ROM and TWRP recovery becomes available for your device in the future, you will be able to flash it by following the instructions provided by the developer. Keep in mind that installing custom ROMs and recoveries comes with some risks, and it is important to backup your data and follow the instructions carefully to avoid damaging your device.
Good evening, can you tell me the correct procedure for how to Root the Cubot p50 smartphone? Thank you.

Thanks for your work on the Cubot phone .Im a fan of them also. I found that twrp recovery 3.40 works on the Note 20/20Pro you just have to flash vbmeta BEFORE and AFTER you flash twrp to the device. Im also seeing separate websites claiming twrp 3.40 is also used with the Cubot P40 model. I dont see why it wouldnt work with the P50. Its worth a shot. Also theres alot more "familiars" with Mediatek phones like these in Hovatek forum. Since you already have information on how to root maybe consider starting your own P50 thread over there.

I get it, but I have to flash the .bin to remove the yellow/red state on boot. I don't know how to install the lk.bin file. If you can help me. Thank you.
Ah I see, you're rooting the phone first. Ok I've just checked my own notes on this, so, if you have edited the lk.img file as described in that Hovatek thread, then do as follows:
When flashing with SP Flash Tool, make sure the correct lk.img file is chosen as SP Flash Tool chooses lk-verified.img by default (click along to the right of the file list under "Location" and choose your edited lk.img file here).
OR, flash with ADB (fastboot flash lk lk.img).
Then install Magisk on your phone if you haven't already.
boot.img is for rooting the phone, lk.img is only to remove the orange state message and the 5 second delay when the phone boots, it does not actually remove it's orange state and is not needed for the phone to be rooted.
To un-root, you should just flash the original boot.img and lk-verified.img from the stock firmware ROM file.

Good morning. Thank you for the information given.
I wanted to ask: is it necessary or useful to install an antivirus on your smartphone now that it's been rooted? Thank you.
I haven't but that's just down to personal choice really. It's certainly useful if you like to try stuff from unknown sources, although personally I've rarely encountered viruses on Android. I'm not saying they don't exist though.
Have you successfully rooted your phone then? What about TWRP, have you tried that yet?
