Can i root now in beta 2 ?
I got the same result as you guys ,
the recovery installs correctly, load correctly , the system won't.
also stuck in a boot loop
Any news , about this recovery?
I'am waiting for it , looks promising despite all .
@Mijotchi Thanks for your time and effort .
Boot Loops in recovery ? Beta and Useless... why on earth is there no disclaimer letting anyone who is desperate to try this know that in the OP ?? Just tossin it out to see how many you can harm first ? not kool.
Works for the a21 o cual funciona para hacer root en el A215u
Does this work properly or does it just boot loop? I have this device as my main phone and I wanna install a custom recovery and maybe a custom ROM.
my device is saying -- device binary is 0x5 and this is 0x0 ? how to fix that
Probably like all other phones... Install TWRP and reboot straight to recovery. Format Data then flash Multidisabler then reboot.
I recommend you join the Galaxy A21s group, it contains the updated TWRP.

This recovery can be flashed successfully but it does not detect external sd. And when I format data to solve decryption it causes bootloop
Please fix the issue of not detecting external SD

Let’s start with the installation process
First you need to unlock your bootloader. You can do so by enabling developer settings first, enable oem unlocking, then shut down your phone, hold volume up and down at the same time and while holding them plugin your charger. Your phone now should show a green screen with instructions to unlock the bootloader. Just follow them and after the unlocking your data should get wiped. After that your device will boot up and land in setup screen. Do not setup anything, just skip as much as possible, because your phone will get wiped again. Enable developer settings and make sure oem unlocking is greyed out and enabled. (If it does not show up, connect to a network first!)
Now you need to overwrite vbmeta partition, so you can flash third party partitions. Download vbmeta_disabled.tar then go into download mode on your device. Put vbmeta_disabled.tar to userdata in Odin, click start. This should finish pretty quickly, so pay attention when your device reboots, because you need to boot into recovery (Hold power and volume up after the screen turns black). When booted into recovery, wipe your data and reboot normally into system. Now you can setup your phone as usual and make sure oem unlocking is still greyed out and enabled!
Time to flash recovery. Download (link is at the end of this post). . In Odin put the tar file in AP and simply hit start. Congrats you now have TWRP installed!

I followed your steps to no avail. First try, twrp didn't even boot up completely as it was stuck in the twrp logo screen. My second attempt was wiping data first using the stock recovery, then flashing twrp. Twrp booted up and I was happy as heck, but the touchscreen was unresponsive. I've completely set up my phone again after giving up. I wouldn't mind losing all my data again just to gain root, but I don't want to lose it for nothing
Now it just doesn't load further than the logo! !(

Is anything working? Decryption? Back-up? Restore?
I have saw the a70 page and it included many custom roms. Is it easy to port it over to the a80? I really want lineage os on my phone. Thanks
(I have an SM-A8050)
@blackbuga ; how about detail explaining about sg7 firmware how can we get it? what about give us step by step way of unlocking until flash twrp within provided link donwload files we needed, & last could u gv us stock recovery img for emergency used while we faced some trouble like bootloop or something else we dont expected. so we dont needed to flash whole firmware stock & make us felt safety & shortcut the time of we got trouble. thx for great works
Hello blackbuga,
I recently installed your unofficial TWRP-build for the A80.
I want to let you know that it is impossible to flash ROMs successfully. I am a TouchWiz developer since 2016 and I wanted to continue with OneUI.
So, I was porting the A71 firmware, but it didn't let me install the zip. It ended with the Error 7.
Here's a part of the log:
" -- Setting ROM Permissions
ApplyParsedPerms: removexattr of /system/system/usr/srec/en-US/wordlist.syms to 0 failed: Operation not supported on transport endpoint
ApplyParsedPerms: removexattr of /system/system/usr/srec/en-US/wordlist.syms to 0 failed: Operation not supported on transport endpoint
script aborted: set_metadata_recursive: some changes failed
set_metadata_recursive: some changes failed
Updater process ended with ERROR: 7 "
It seems like it's a problem of the recovery. I hope to get an answer from you.
Greetings

Flash Galaxy A20e TWRP.tar via Odin or heimdall
Reboot into TWRP AS SOON AS THE FLASHING PROCESS IS DONE because otherwise TWRP will get replaced with the stock Android recovery
If you want to flash a GSI, skip to step 7
Factory reset in TWRP and reboot to stock
Wipe everything in TWRP excluding SD Card / USB OTG
Put a GSI image file onto an SD Card, alongside GSI_Fix_boot.zip and Disable_Dm-Verity_ForceEncrypt_03.04.2020.zip
Flash the GSI image, flash Disable_Dm-Verity_ForceEncrypt_03.04.2020.zip, flash GSI_Fix_boot.zip, wipe cache and reboot.
Enjoy

Hey thanks for this, I´ve got a few questions about the process that might also help others.
Do you recommend this method of rooting still over the new method using Magisk?
Do we still need to wipe everything in TWRP after first boot? And what specifically steps should we take to wipe?
Can you recommend any specific GSI images that are known to boot on the A20e (A202F) because so far I've tried LineageOS 17.1 / AOSP system -quack-arm64-ab-gapps.img and system -quack-arm64-ab-vanilla.img / Crdroid and nothing gets past the loading icon.
Do we still need to flash Disable_Verity_ForceEncrypt and GSI_Fix_boot.zip if not installing a GSI ?
a few notes
for anyone else. It helps if you boot into the rom and install magisk manager via APK (recent version is fine) before installing it via TWRP. After I did that rooting worked properly.
Lost ADB for some reason though, might be unrelated.
I also think that the a20e (SM-a202f) is an A device and not an A/B partition device at least according to treble check app.
ADB and USB connection / USB OTG does not work

1. This method does use Magisk
The tar file contains boot.img patched with Magisk
It also contains recovery.img and vbmeta.img
2. The boot.img is from Android 10 firmware so you need to upgrade to Q first.
3 there is a step missing in the instructions
It should say
6. Reboot the A20e into TWRP and mount everything you can.
Click Wipe then Format Data (not just wipe) - don't restart
Flash Disable_Dm-Verity_ForceEncrypt
Reboot to recovery and wipe both caches
Reboot system .

Anyone got a guide to installing magisk on this device?

I've tried patching the stock firmware AP with magisk through the magisk manager and flashing it to my phone... keep getting vbmeta error.
Seems to also happen with other Samsung phones, but can't get it to boot (or it goes back to odin mode or bootloop).
error verifying vbmeta image: invalid vbmeta header (6)
Is the error I'm getting while trying to boot...
Doesn't matter if I flash magisk or twrp... it's the same everytime.
Now I'm getting the OK_NOT_SIGNED (3) error.
Can still not boot into recovery or boot my phone with magisk installed.
Flashed stock firmware and will wait until there's any news on fixing this.
@paradox1990 check here: https://forum.xda-developers.com/galaxy-m30/how-to/testers-m-series-t4169511
Let me know if you are okay for testing, and I will try and get a working ODIN (until TWRP comes).

Hi, I was intending to restore my lenovo y90 to it's original state after root by flashing back the stock boot.img to boot partition by using flashboot and lock back the bootloader by command fastboot flashing lock after that using QFIL to flash the stock cn rom. Everything was going well till after flashing of the stock CN rom the screen show firmware corrupted and boot to fast boot mode, from there it kept stuck in fastboot and when I tried to unlock the bootloader using command fastboot flashing unlock it show FAILED (remote: 'Flashing Unlock is not allowed')
fastboot: error: Command failed. Now I am stuck with unable to flash stock rom or install any recovery. When I choose recovery will only boot loop back to fastboot. Very much appreciate any help.

You shouldn't lock back bootloader before downgrade because google implement anti roll back. As what I read in China website once you lock back you cant downgrade anymore. There only one choice is to bring to service center. There only one qfil firmware for y90 which is 563. So I assume your version is higher than 563. Only unlock bootloader able to downgrade and flash qfil
I don't believe that is how the anti-roll-back feature works @darkidz555 . Considering the phone launched with android 12 the .563 firmware should fix his issue. You can find the QFIL package here and it appears you have to pay 20 rmb for it. Maybe someone already has it and would be kind enough to offer it here on xda?

I own y90 and this is how google anti rollback work for y90 and I already have qfil firmware you don't need to pay you just go to zui website and forum all the Chinese people share around the firmware and have step by step guide for root , downgrade , qcn , persist and etc in their WeChat group with all the firmware sharing inside the group as well. The Chinese people explain very well regarding this issue ONCE YOU LOCK BOOTLOADER AND FLASH QFIL THERE NO WAY TO SAFE YOUR DEVICE BECAUSE OF GOOGLE ANTI ROLLBACK. maybe Lenovo did something themself that why they never plan to release y90 for global.

Have you attempted to wipe data? Plug in USB cable to side port and type: fastboot reboot fastboot , it will reboot into fastbootd and select wipe data and see if it boots.

Use Google drive or make an account on Androidfilehost to share the firmware. I notice you posted that you have a Sahara error when trying to flash through QFIL, if that is the case, then you need to install the correct Qualcomm drivers. Upload the firmware first, that way it can be reviewed to see if it is in fact for an L71061 (Y90).

Hi, I was intending to restore my lenovo y90 to it's original state after root by flashing back the stock boot.img to boot partition by using flashboot and lock back the bootloader by command fastboot flashing lock after that using QFIL to flash the stock cn rom. Everything was going well till after flashing of the stock CN rom the screen show firmware corrupted and boot to fast boot mode, from there it kept stuck in fastboot and when I tried to unlock the bootloader using command fastboot flashing unlock it show FAILED (remote: 'Flashing Unlock is not allowed')
fastboot: error: Command failed. Now I am stuck with unable to flash stock rom or install any recovery. When I choose recovery will only boot loop back to fastboot. Very much appreciate any help.

The real way flash y90 QFIL is using flat build select ddr file and select context.xml and then download. But since you lock your bootloader if possible try to unlock before QFIL else you will be hard Brick. Y90 can't be flash using normal meta build and select ddr and rawprogram0 and patch0. You must flash using context.xml. I've been back and forth downgrade and update multiple time can say more than 20x.
Thanks for the advice but the problem for me now is that I cannot unlock boot loader. Previously when boot loader was unlock I can easily flash the ROM.

That what the info I get from Chinese y90 WeChat group. If you lock your bootloader then flash QFIL firmware while bootloader is lock there no other way to unbrick need to bring to service center because of google anti rollback. One question when flash QFIL firmware did it fully flash until system ownself reboot or Sahara error while flashing. If you fail to flash then it might have a chance to unbrick your device. If fully flash then even then Chinese y90 group also no way to unbrick. Your last choice is either reboot to fastbootd not normal fastboot is fastbootD and wipe data hope it boot else I cant help much. Try fastboot flash sn.img and then fastboot oem unlock-go again hope it help good luck
Thanks

Be it work or not work please update here at least other user get the idea.
This is nearly similar with your problem I guess chinese brand tend to make their own stuff. Lenovo did it differently by bricking your device if you flash edl firmware with bootloader lock
Back in July, Xiaomi rolled out MIUI 10 Global Beta 8.7.5 for eight Xiaomi devices. When users installed the update on their Xiaomi Redmi Note 5 Pro, they unknowingly flashed a build with anti-rollback protection enabled. Users who didn’t like MIUI 10 Global Beta found a nasty surprise when they tried to re-install the latest MIUI 9 Global Stable ROM: their phones were bricked! This wasn’t the kind of brick that you could fix by restoring a TWRP backup, flashing a new ROM, or using MiFlash to restore to a factory image. This is a hard, unrecoverable brick that requires the use of EDL mode to fix. But EDL mode isn’t accessible unless you have an authorized account, so many users were left with no way to fix their phone except sending it in to an authorized service center or paying to use someone’s account with EDL access. In this article, we’re going to explain everything you need to know about Xiaomi’s new anti-rollback protection so you can avoid bricking your new phone.

I know it is kind odd but I am on the path to root my y90... I have no ideia where to look at it. I see people commenting about chinese group but would you kindly point me to the root files needed (maybe twrp build too) not sure if there is a magisk port or whatever.
Thanks in advance

In order to root u need the china firmware and need magisk to create a modified boot.img.
Ok, I have the firmware, question is, will it work ?
I am king worried about brick my phone, do you tried that before ? did it work fine ? I ave been doing this for a while on other brands but lenovo seems to be a complete different beast

It does work but remember to enable developer option and USB debugging and unlock boot loader and not to lock it back before doing the root.

A maneira real do flash y90 QFIL está usando o arquivo ddr de seleção de compilação plana e selecione context.xml e, em seguida, faça o download. Mas desde que você bloqueie seu bootloader, se possível, tente desbloquear antes do QFIL, senão você ficará com o hard Brick. Y90 não pode ser flash usando meta build normal e selecione ddr e rawprogram0 e patch0. Você deve fazer o flash usando context.xml. Eu fui e voltei de downgrade e atualização várias vezes pode dizer mais de 20x.

Olá amigo, sou brasileiro e uso o Google tradutor, poderia fazer um vídeo ensinando como fazer root e instalar o TWRP no Lenovo Legion y90, estou aguardando meu aparelho chegar e não tem idioma português do Brasil para isso, eu acredito que um módulo de tradução ajudaria muito, e com Root e TWRP eu poderia realizar esse procedimento!!!
darkidz555 said:
You shouldn't lock back bootloader before downgrade because google implement anti roll back. As what I read in China website once you lock back you cant downgrade anymore. There only one choice is to bring to service center. There only one qfil firmware for y90 which is 563. So I assume your version is higher than 563. Only unlock bootloader able to downgrade and flash qfil

Yeah it worked, just follow the instructions in the wechat group.
Am currently rooted. Also note the Ramdisk yes or no in magisk to know whether to flash recovery or boot.img. in the wechat group the boot.img already provided for all roms released till date. Just patch and flash. Oem should be unlocked in develioer setting, then Bootloader must be unlocked in fastboot, before proceeding never lock back boot loader. As I mentioned before read the instructions carefully in the wechat groups.

TWRP FOR THE A52 5G! (With issues)
Help needed!
Are you someone that has ported TWRP before without any issues?
Or are you someone that knows how to fix any problem that has been listed in the 'Additional Notes' section?
PM me. We can work together to fix the issue(s)
Note
Code:
* Your warranty is now void.
*
* I am not responsible for bricked devices, dead SD cards,
* thermonuclear war, or you getting fired because the alarm app failed. Please
* do some research if you have any concerns about doing this to your device
* YOU are choosing to make these modifications, and if
* you point the finger at me for messing up your device, I will laugh at you.
Additional Notes
Code:
THIS RECOVERY IS NOT FULLY TESTED!
There are atleast these issues:
1. MTP Does NOT work. (Not with computer or with OTG)
2. NO access to your SD cards
3. Incorrect resolution (TWRP is 1080x1920, phone is 1080x2400)
4. Temperature sensor doesn't work.
THERE MIGHT BE MORE ISSUES I DO NOT KNOW OF! FLASH AT YOUR OWN RISK.
How to install?
First of all you need an unlocked BL. This is extremely easy to do and there are a lot of guide online.
Download recovery.tar (TWRP) from this post.
Select the AP slot in Odin
Disable auto reboot in Odin
Flash

No problem.
Hi,
Firstly, thanks for doing this!
Secondly, I've been trying to flash a zip (BluetoothLibraryPatcher) but I cannot find a way to get TWRP to read a zip file. Things I've tried:
From the device itself: The data partition is encrypted. twrp decrypt (in the TWRP terminal) says "No crypto support was compiled into this build".
From ADB Sideload: It gets stuck on "Starting ADB sideload feature..." for 5 minutes, then fails.
From MTP/USB OTG: As you say in your post, neither MTP from PC nor from a USB flash drive works.
Would you have any idea of how I can get TWRP to read a zip file to install?
Thanks!

Hey, you can use commands by just being on the home screen of TWRP. ADB push <file location and name> /sdcard

Btw, afaik the encryption problem isn't something I can remove.
This is fantastic to see! Nice work.
Have you tried any custom ROMs with this? Do any of the current custom ROMs (like Lineage OS) support A52 5G, or are we still a far way away from that?

Hey. I've not started a custom ROM yet. I've been busy with school mostly. I will probably start developing Lineage OS as the first custom rom.

Yep thats me. I can't upload a kernel file on github as its 25mb+ So the device tree won't be complete without it. I'll change the post.

I recommend using Git LFS for that, more info about it here: https://git-lfs.github.com/
I created a device tree myself long time ago as well, was just missing the kernel
I may sell my U1 for the Dual Sim model so I can root. I need parts of this lol
Any progress?
I just can't wait for LineageOS
@Things405 I have GitHub pro if you want someone to host the device tree on there... I'm on https://github.com/SImPilotAdamT/
Also by A52 5G do you mean the A526B?
Also for some reason I can't unlock the bootloader in my device... I have the A526B international model. https://forum.xda-developers.com/t/unable-to-unlock-the-bootloader-a52-5g-sm-a526b.4476861/
TWRP 3.7.0 is out with the support for decryption on Android 12 to be able to backup firmware. Pls update, thx
I'm sorry to have left you guys hanging! I've been too busy with personal stuff but I will get back on this as soon as possible.
flashed in A526BXXU1AUAH, when press buttons for recovery, it freeze on boot logo
does this also work for the a52s 5g version?
