Hello Forum users!
Since I have lots of time right now i wanted to do some fun stuff with my Z2 Play XT17170-09, which was my previous daily driver. So i installed the custom twrp i found on xda (here), rooted it with the magisk zip (idk what the version was) and everything was fine. Until I discovered Motorola put a 32 bit ROM on there, that is. So i wanted to flash a custom ROM (also from xda) but without success. The Phone got stuck in a bootloop. I thought: no problem, I have a full backup. TWRP wasn't accessible anymore. I somehow managed to get into TWRP and restored my BU, but it didn't boot anymore (not my main problem but if you you have an idea why, please also tell me). I found the Stock ROM for my exact model and software channel (reteu) and flashed it with mfastboot, as shown here. I finally got it to work, with ID: bad key, even though I had id: N/A before this whole mess, but ok im fine with that. But now the ROM overwrites my TWRP with the stock recovery and if I try to root it with Magisk zip it gets stuck on the device unlocked, cannot be trusted (...) screen and it won't boot anymore. I can reflash the whole stock firmware as above with everything working, but I still don't have a rooted phone then. Does anyone (please?) have an idea on why this happens? I appreciate every answer, I am trying for 3 whole days already. My guess is that the boot partition gets corrupted somehow during flashing, but please correct me if that's wrong.
Thanks in advance
There's a guide somewhere here, but in short:
to get Magisk working, you must either:
A) backup and restore system and data before flashing Magisk
B) go in TWRP to advanced and in command prompt write:
echo KEEPVERITY=1>>/data/.magisk
echo KEEPFORCEENCRYPT=1>>/data/.magisk
either before or after flashing magisk, don't remember. Rather both.
If you want to play with custom ROMs, you can try GSIs. Guide: https://forum.xda-developers.com/z2-play/how-to/updated-guide-project-treble-gsi-t4063193

I tried, but the error remains the same. I simply installed a custom ROM and rooted it, even though i wanted to keep it on stock firmware. Anyway, thank you very much for your answer!
This problem is common in Stock Oreo
You messed up, and badly.
The first thing you need to do before installing a 64-bit ROM is install a 64-bit recovery.
But in your case this isn't possible if you don't fix your issue first, as Oreo has extra steps to make Magisk work, these extra steps can be entirely skipped (because they are no longer needed) if you flash Stock Pie instead.
The easiest way to flash TWRP your phone without the stock recovery fcking up with it, is through Stock Pie.
Since you have unlocked bootloader, you only need to get the Stock Pie ROM and flash it through adb fastboot.
Note: partition (gpt.bin) can only be upgraded. If you upgrade gpt.bin from Oreo to Pie, you won't be able to downgrade it as the security downgrade will prevent it. So in the case it gives you an error avoid flashing this file.
If you decide to flash Stock Pie, also skip the modem file (modem-HLOS.bin), you want to avoid that modem file from Android 9 because it has audio issues during calls when installing ANY custom ROM.
Instead, preserve the modem file from Stock Oreo as this one doesn't have any issues with custom ROMs.
Also make sure you issue the oem mode commands, there is one guide that doesn't have these, if you skip them, the USB (and MTP) connection on PC won't work at all.
fastboot getvar max-sparse-size (1st command)
fastboot oem fb_mode_set (2nd command)
fastboot oem fb_mode_clear (last command after you flash the last file, just before issuing reboot)

I have also read you need to flash Magisk 19.3 or older, then you can update Magisk through itself (the Magisk App)
If you try to flash Magisk 20 or newer it could cause bootloops in very specific cases.
Here is a solution with Magisk Manager 7.5.1 and Magisk 20.4
Before patching, make sure both encryption and verity are checked
Patch the boot.img and flash it in bootloader
Done

Greetings!
After installing the October security updates (bringing my device to NBD90W) I decided to unlock my bootloader and install TWRP. However, I can't seem to get TWRP to "stick" - flashing seems fine, and rebooting into bootloader and into TWRP recovery all proceeds fine. However, as soon as I reboot my system, TWRP seems to disappear and the stock recovery reappears.
Am I doing something wrong here? This is the exact process I followed on my Nexus 7, without any problems.

You should be able to run twrp-2.8.7 without any problems. I believe if you want one higher you might need to format data (decrypt is what I do).
Also, here is what instructions on TWRP say to make it stick.
Note many devices will replace your custom recovery automatically during first boot. To prevent this, use Google to find the proper key combo to enter recovery. After typing fastboot reboot, hold the key combo and boot to TWRP. Once TWRP is booted, TWRP will patch the stock ROM to prevent the stock ROM from replacing TWRP. If you don't follow this step, you will have to repeat the install.

Thanks for your response. I am following the directions on TWRP's website, so it must be another issue.
I will try the version you suggest to see if that works. Why would I need to format data to install a later version?

I believe it requires you to be decrypted. Formatting userdata will wipe your data so make a backup first.

Flash TWRP from bootloader.
While within bootloader use vol down to select recovery and press power to boot into recovery.
Install SuperSU.
TWRP will stick.
If you boot with stock recovery even once, TWRP will get replaced.

If you are using NBD90W I suggest you use the unofficial TWRP 3.0.2-3 that was posted a few pages back from the last post on the TWRP thread.
TWRP 3.0.2-0 won't decrypt Android N (will decrypt MM)
TWRP 3.0.2-1 has a major EFS bug that will brick your phone on restore
TWRP 3.0.2-2 has that EFS problem fixed, but has another problem where larger parttitions don't get backed up correctly.
TWRP 3.0.2-3 has both previous problems fixed.

I didn't read the whole post but decrypted user partition isn't directly related to why your TWRP is disappearing.
When you boot with a stock image, it will replace your recovery with stock.
If there is just 1 byte change with your boot.img, it won't do that.
Installing SuperSU will patch your boot.img, thus it will no longer replace your recovery with stock.
You could flash a modified boot.img instead of SuperSU, but then you are depending on someone else creating a modified boot.img for you (or you creating it yourself). If your goal is to have root installed, then SuperSU will patch boot.img on the fly during install so no need for extra step.
Again, the overwriting of TWRP with stock recovery is not directly related to the modifications done to boot.img either by someone else or by SuperSU install. If you had done any change to boot.img even if it is off by 1 byte, TWRP won't be replaced by stock recovery.
IMO there is no reason to run decrypted with latest OS, but if you wanted to, the only requirement is you have dm-verity disabled in the boot.img. Both the custom boot.img and the SuperSU install would do this for you.
After you have dm-verity disabled (either by SuperSU install or installing custom boot.img), boot back into bootloader and do
fastboot format userdata
From that point on, as long as you *never* boot using stock boot.img your userdata will remain decrypted. If you ever boot with stock boot.img, by mistake, it will proceed to encrypt your userdata. Then you'd have to go through the same procedure again the decrypt (losing your userdata in the format step)
The proper way to upgrade is to flash boot.img, system.img, vendor.img in fastboot, then immediately (from bootloader menu) boot into TWRP recovery, and install SuperSU. Then everything will be preserved.

Listen to this guy. You can start with the old one if you want then upgrade to the new one later but Supersu modifies your boot.img for you. Like he said, after Fastboot flashing them, Fastboot reboot and before your phone boots up, boot right back into recovery. This will make TWRP stick.
Wow, this post was SO HELPFUL.... Haven't rooted in a while, recently replaced our Nexus 5's with 5x's (on NBD90W) and hadn't felt the need to root. Plus it's gotten so much trickier even with Nexuses.
Anyway totally familiar with ADB/fastboot etc to flash stuff.
I still need to oem unlock and wipe still (bleh).
But after, one thing that's confusing me, to then root is a *custom* kernel (boot.img) needed now? Made specifically for (at this point in time) NBD90W? Or can stock boot.img be flashed then boot straight into TWRP and flash whatever is the latest SuperSU? Are all SuperSI "systemless" now?
Also you stated "IMO there is no reason to run decrypted with latest OS". I have noticed VAST performance improvement with Nougat. Is this why you feel no reason? Would we not still gain even more speed back? (it was so sad watching my wife's old Nexus 5 booting 6.0.1 faster than my 5X).

I've always decrypted but that is my personal choice. All I do to root afterwards is flash SuperSU-v2.7.8. That is it. You can adb sideload it (i use twrp for that) or flash it in twrp if you have it already on your phone).

You must have a customized boot.img now for root. What customizations you absolutely need to have in boot.img is dependent on how you want root installed, but since you are modifying boot.img, you might as well just stick all the changes you need in boot.img and leave /system untouched.
The default install for SuperSU will make the required changes to whichever boot.img you currently have installed on your system. Generally that consists of disabling dm-verity (integrity check), making encryption optional (not absolutely required), making sepolicy security changes, and adding init script support to load SuperSU binaries later in the boot process.
There are configuration parameters you can feed into SuperSU install to force it to install root on /system instead of systemless, but I would just suggest systemless. It is a cleaner install IMO.
So install the stock boot.img and boot directly into TWRP from the bootloader menu, then install SuperSU and it will modify the boot.img you have installed (and back up original)
The only requirement to keep TWRP (and/or decrypted userdata) is to NEVER boot the phone using a stock boot.img. If you always immediately install SuperSU after flashing the stock boot.img that will satisfy that requirement.

for some reason, when i fastboot installed twrp (after usb debug/unlocking bootloader) I kept getting mount errors when starting twrp. I tried flashing purenexus rom, wipes dalvic, system, data. then my data partition was 0. couldn't mount data part. to copy purenexus or system stock image. I ended up having to use my windows pc to wugfresh it back to life. has been a crazy night. I need coffee.

Did you reboot after unlocking or go ahead and install TWRP right after unlocking?
I tried, but I kept getting the " cannot check for corrupt system because bootloader is unlocked" message, and it never fully booted. I managed to fix the 0data partition by fastboot format userdata, but pure Nexus never worked. It tried to boot, but it stuck on the spinning Google logo thing
Update: followed pure Nexus instruction; unlocked bootloader, then let it boot once to device setup. Restarted in fast boot, flashed twrp. Rebooted, went into twrp, formatted dalvic, system, user data and cache. Flashed pure Nexus from then gapps according to pure Nexus download page. Reformated dalvic and cache. Rebooted, stuck on Google logo, this time did not do its spinning thing. Have I missed a step??

I do not believe Pure Nexus is a Nougat Rom. Try starting over and flashing a Rom compatible with your firmware.
On my way to installing LineageOS I tried to downgrade Android version 11 -> 10. Unfortunately I used the WRONG INCOMPATIBLE firmware files from google's website (I think for 3 XL), that's why I have a brick now. ''Device is corrupt and no bootup possible.''
Access to Fastboot and STOCK Recovery Mode is possible.
Bootloader is Locked Now (it *was* unlocked before for flashing the firmware)
ADB is not working (since I'm getting stuck on ''google'' symbol when booting up I can't go to Developer Settings)
Factory Preset from Recovery Mode fails: ''can't send spi messages.'' Same Brick occurs.
With No Access to ADB (is it possible to set up from fastboot mode without enabling it in den Developer Options?) I can't try stuff.
And with the bootloader locked no way to flash a new Rom right?
I have NO IDEA what to do next, any IDEAS??
Thank you!!

Since you can get to recovery you should download the latest ota and sideload it from recovery.
https://developers.google.com/android/images
you should flash the stock image from recovery. Basically unzip it all and just run "flash-all.bat"

You need the BL unlocked to flash unsigned/unofficial images, so make sure yours is unlocked. That being said, I'm not sure how solid twrp is for our device, I've never tried it. Twrp was/is a little iffy for android 10 never mind 11. Most around here just use fastboot to do what needs to be done. Most of it is pretty quick and painless, and twrp is not really necessary.

I'm pretty sure you would have to downgrade to android 9 (pie) and install a custom kernel to get twrp to install. Unless you want to rock android pie - like I currently am (Bootlegger's 9 - I like my smartbar customizations) - it's best to give up on TWRP and just use fastboot commands for android 10 and up.
If you do decide to downgrade to pie the elementalX kernel (ElementalX-P3a-1.06) works fine with twrp and is available on their site. Temp boot twrp via fastboot, flash kernel, flash twrp zip file, reboot to recovery and flash magisk zip for root (if you want root). But it may be hard to find older pie ROMs out in the wild to flash since devs have dropped support and will be focused on android 10/11.

Unlike most of the LineageOS Tutorials out there is used the Custom Recovery from Lineage to install LIneageOS! It was super easy, a few ADB commands and here it is. No Root, no TWRP whatsoever.
Follow wiki lineageos devices website instructions. Here you may also find the recovery data.
Thx guys/girls!

Cool. No more soft brick for you :good: Congrats on sorting things out. :highfive:
BUT I still cannot install TWRP Recovery on LineageOS 17. I am getting the same problem as quoted below.
I want to perform Nandroid Backups, any other way to that if TWRP doesn't want me? Maybe with a Magisk Root and some app from F Droid?
?

Thank you, this worked perfectly fine, since you don't need an unlocked bootloader to flash this system image.
However, I am facing a new problem on my way to installing TWRP Recovery Image...!!
CMD gives me THIS log:
Writing 'recovery' FAILED (remote: 'Not allowed to flash (recovery)')
fastboot: error: Command failed
- the device is unlocked (I even relocked it and unlocked it again, didn't work)
- I tried one other older .img for my phone from official twrp.me website, didn't work
Any Ideas?

Twrp doesn't work very well on android 10 and above, there is a twrp install guide around here, but not much has come from it. When was the last time anyone actually made and used a nandroid backup? Not that backups aren't important, but that's a little antiquated. Besides, most are really trying to backup data, which is a shared partition on A/B devices. Generally, restoring data on A/B devices causes more problems than anything. Most data backups can be done with an app and/or making a backup of your internal storage. As for more sensitive things like your persist partition and whatnot, you can always use the 'dd' command to back those partitions up.
I should clarify, restoring nand backups of data causes more problems on A/B devices, apps that restore data and settings tend to handle it better.
Now having a different problem
I tried to install Magisk following this guide https://magisk.download/root-pixel-3a-3a-xl/
When I try to flash magisk_patched.img in fastboot, it flashes, but reboots to fastboot with "error boot prepare" displayed.
I am stuck in Fastboot now.
How can I get out of that?
I used the boot.img from the google firmware android 10 I built Lineage on. Should I use a boot.img from LineageOS .zip? Is there anything like this?
What is dm-verity?
Can I get to my previous unrooted device?
I have a Pixel 3aXL with LineageOS 17
''bootslot: b
enter reason: error boot prepare''

Reflash the boot.img from Los17 to get back to proper boot up, then patch Los17 boot.img and flash that to have root.

Where is the boot.img from Lineage? There is no such file in the Lineage folder I downloaded.

A lot of devs wil upload the boot.img separately when they upload the rom, so wherever you downloaded Los from check there. If you just have a payload.bin file in your zip, you can always dump it and grab the boot.img there. You could always just reflash Los period to get boot back, then us 'dd' command to backup your own boot.img.
custom recovery for lineageos 17 based on android 10?
teemothay said:
I'm pretty sure you would have to downgrade to android 9 (pie) and install a custom kernel to get twrp to install. Unless you want to rock android pie - like I currently am (Bootlegger's 9 - I like my smartbar customizations) - it's best to give up on TWRP and just use fastboot commands for android 10 and up.
If you do decide to downgrade to pie the elementalX kernel (ElementalX-P3a-1.06) works fine with twrp and is available on their site. Temp boot twrp via fastboot, flash kernel, flash twrp zip file, reboot to recovery and flash magisk zip for root (if you want root). But it may be hard to find older pie ROMs out in the wild to flash since devs have dropped support and will be focused on android 10/11.

I got Lineage 17 w/ Magisk root running now and want to perform a full NANDroid Backup.
After some research it seems crucial to have a custom recovery like TWRP for that. There is the online nandroid thing - but I would need CWM or anything like this to restore?!
So my question is
a) is there another custom recovery (compatible with Pixel 3a XL w/ lineage 17 based on android 10) I can install and perform Nandroid backup with?
b) any other solution to perform this backup and restore? I heard there are cmd commands for that as well , but I'm a noobie not so sure to do that.
of course there are several apps out there to backup data.. but I don't trust ''any'' app to get root permission. In F Droid I couldn't find what I was looking for.
thank you for help!
I have an ATT LG V40 on android 8.1. The phone is already rooted and has magisk installed. I have been unable to get TWRP installed so I can flash a custom rom. It seems that being on android 8.1 is causing issues, but I am not really sure. I followed this guide: https://forum.xda-developers.com/t/twrp-lg-v40-judypn.3970111/ and when I send the comand to flash TWRP in the command window is says the flash is finished and my phone boots up, but it doesn't seem to do anything. Any help would be greatly appreciated, thanks.
You need to use LGUP to get to 9
Noob question but did you installed and tried magisk manager(I bet you already have) and flashify(searchable on Google) (magisk manager grants root to flashify and flashify installs twrp from storage)?
Are you certain that you're booting in to recovery? Many phones have an advanced reboot menu option on the developer settings. If yours doesn't I recommend an app like Simple Reboot.
If you're not certain that it's installing the recovery correctly have you just tried installing TWRP.zip from Magisk?

Which 'command', specifically, are you typing in when you say you are 'when I send the command to flash twrp'? The only command in those directions are to boot twrp, not flash it.
After you boot it, then you need the advanced section so you can recovery ramdisk, which will inject twrp into the current boot partition (and it keeps boot intact).
If you want to use current aosp roms, then follow the 'metadata' sections as you'll need that version of twrp for those roms.
cheers
Hi, I got myself an used Motorola Moto G7 play (XT1952-1) with Android 10 Stock update (Build QPYS30.52-22-8-9) and just can't successfully install TWRP on it. What I did:
- Bootloader unlocked
- TWRP temporary loaded with fastboot (fastboot boot twrp.img)
- In TWRP 'Iinstall' selected the matching TWRP .zip and it said it was installed in both slots a and b.
But then, when I select 'restart to bootloader' and try to launch recovery, I get a bootloop (black screen with (N/A) in the top left corner. The OS as such still starts normally. So I guess the main problem here is the bootloop when trying to launch recovery...?
I tried installing over booted TWRP with unmodified boot.img and with Magisk patched boot.img, same result. The G7 play does not have a separate revovery partition, recovery is included in the boot.img
I used the TWRP files (EU) and instructions from here:
Motorola Moto G7 Play
Disclaimer:Team Win strives to provide a quality product. However, it is your decision to install our software on your device. Team Win takes no ...
twrp.me
My stock firmware is XT1952-1_CHANNEL_RETEU_10_QPYS30.52-22-8-9_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip from here:
lolinet mirrors - firmware, software, iso etc.
lolinet mirrors - powered by h5ai
mirrors.lolinet.com
Am I missing something? I've now searched for days (most info is outdated, taken from other places/Motorola phones with just 'G7 play' added, or is ambiguous); so can anyone *PLEASE* help me? Does anyone have a G7 play of the same type with Android 10 Stock who has successfully installed TWRP and was able to access the Recovery afterward without being stuck in a loop?
I also can't create a TWRP backup with a fastboot booted TWRP because system (and internal SD too) seems to be encrypted, and I don't seem to be able to deactivate this in the phone. Is this normal? Some places say that TWRP can decrypt when it's installed permanently...
Or could anybody patch the boot.img in above Firmware and add TWRP for me so I can just flash the boot.img?
Thanks in advance... please reply noob-friendly.
Still need a patched boot.img? Attached you'll find a boot.img with TWRP installed. I followed your links to get boot.img + twrp.img.
NO MAGISK INSTALLED!!!​Please patch before flashing if Magisk is already installed.
I put a log of the repack command into the zip that is showing the checksums of the boot header. Just to have a proof.

Thanks for trying to help, but this boot.img behaves exactly like the one I made by following the installation instructions on the TWRP website. I flashed it, restarted bootloader, then tried to go into recovery, and it bootloops (black screen with N/A in the top left corner).
But what I need is a boot.img with a WORKING TWRP recovery (that can actually be launched when recovery is selected...
Any idea why this won't work, why TWRP won't start?
@Alonso_Quixana Try the attached one. It's a boot.img patched with twrp + recovery_dtbo. The recovery_dtbo is part of the twrp.img but TWRP's installer.zip doesn't take it into account while repacking the patched boot.img. Maybe (hopefully!) that's the reason why you're able to boot TWRP but not to install it permanently.
Please try also - in any case! - the patched installer.zip that comes with a recovery_dtbo.
Sadly, you can't flash TWRP on stock ROM, in case you did sucessfully, ROM will not boot and that can cause SIM and VoLTE issues, i did flash it on mine and now VoLTE doesn't work on my phone, you can only boot it in case you want to flash an custom ROM, flash it then reboot into recovery to install GApps on the Custom Recovery that the ROM does install, but since all of the ROMs are arm64, i don't recommend it since you will have constant app restarting when changing from one app to another app

I've seen so-called tutorials on Youtube where someone actually succeeded in installing TWRP on his Moto G7 play (but did not mention which Android version was on the phone), and the TWRP developers too claim that their version for Moto G7 play would work, it even got an official update for Android 10 (alas they never reply to direct e-mails, those snooty guys)... some on XDA even said the flashing of a 'dirty port' worked for them. Were they all mistaken? Or did it work on Android 9? Are all XDA threads and internet posts / Youtube videos misleading / lying?
Are you REALLY sure that there is no way to install TWRP on a Moto G7 play (to be able to create a working backup of the encrypted data partition)? A 'full restorable backup of everything' is what I need...
I'm not sure about Android 10 Stock Rom, but it seems to be a 32bit system on a 64bit Kernel?

It's a 32bit system on a 64bit CPU (Snapdragon 632). That's not unusual for Motorola devices. Open a terminal app and execute uname -a.

I think it only works on certain Moto G7 Play variations or even only on Android 9, also, another way to install TWRP is installing an Custom ROM then flashing an flashable zip of TWRP_11 by SyberHexen on Custom ROM's Recovery
Link to TWRP_11 Flashable Zip

In my case, flashing TWRP, even by following some tutorials made my MetroPCS Moto G7 Play to stop booting and also, VoLTE stopped working, fortunately, i had an EFS backup to restore my IMEI
Android 10 Stock Rom is an Arm (32 bits) ROM, every Custom ROM i tested are Arm64, but i don't recommend any of them since you will get constant app rebooting and notification problems since this is an 2 GB RAM device
Hi all,
I have recently shifted from Samsung A52S to Onpelus 9 PRO.
I'm now a bit confused about flashing method....
I mean :
on Samsung devices, you have to use ODIN ( that is a Fastboot replacement tool ) in order to flash the TWRP and then, on TWRP, you can freely flash any new custom ROM or any other img files, by simply press "INSTALL" button instad of ADB sideload commands.
If I well understood, in order to flash this custom ROM, I have to do that through Fastboot commands before and through TWRP ADB sideload commands after......
My question is : may I flash boot.img / vendor_boot.img / dtbo.img and ROM zip directly through TWRP "INSTALL" button instead ???
If not, can someone kindly explain which is the reason why ?
Sorry for this noob question but I'm doing my first step into Oneplus and I don't want to do a mess.....
Many thanks for the help !
I personally been wanting to know why we no longer can simply flash custom roms via TWRP like we use to. I do believe its got to do with the way the A/B partition works however that does not really answers why we can't just flash via TWRP. Unfortunately, I have not been able to find the answer so I am interested too on why we can't simply flash custom roms in TWRP and have to resort in sideloading or via fastboot. I would think flashing via a zip in TWRP will have less user errors compare to using a command line to do your flashing.
Saying that, I have been flashing via fastboot since I got this phone and even though its a longer process, it only takes a few more minutes.
twrp is not even fully adapted for android 12 or 13 (but who needs twrp anymore?)
I prefer to flash via fastbootd
(is less work for me)
best way is the magisk install

twrp is still the only way to backup the whole rom
it exist a non official version for 12/13
TWRP is the best tool to recover files when the OS does not boot. Since there is no ROM or kernel out there that recommend or uses TWRP for flashing. There is little reason to use TWRP unless is for file recovery. This is in respective to OP 9.
