I had this issue on my old Nexus. Erasing the partition before reflashing worked for me. Are you able to flash another custom recovery like CWM over TWRP?

I didn't try flashing a different recovery. I was going to try using dd to write to the partition.
Do you happen to know which partition the recovery is on?

According to TWRP the partition is:
/dev/block/mmcblk0p25
BTW are you sure your stock recovery img is stock recovery and not twrp masquerading as stock recovery due to some mixup somewhere? where/how did you get your stock recovery img?

Flash full 3.2.6 zip instead
Followed by flashing official twrp
Stop messing up with 3.5.2 (please revise your thread title, 3.2.5 is not 3.5.2)

Or can download flashify and download latest trwp and flash, unless u keep the community build then there is a diff trwp version floating around here

You can boot into twrp without flashing it.

while on OOS 3.2.6 flash the *modified* TWRP and then flash that community build 3.5.2 not 3.2.5. as community build needs that modified twrp to work.. if you wanna revert to other roms.. flash stock OOS 3.2.6 and then flash twrp official and your all good to go..
if you want easy way to get twrp on your phone use that " Tool all in one" it can be found in xda.
Hope that works for you as it worked for me! Cheers!

I'm in this same boat. I am curious if you found an answer. After splash screen my phone will only boot into a black screen. No recovery mode. I've tried reflashing official twrp from fastboot and it says it was successful but phone still wont enter recovery.

happy to help! yes you can get back to official twrp after flashing oos 3.2.4 or 3.2.6.. because for the community build 3.5.2 only that modded twrp will work..

Check on the blu_sp*rk kernel thread.

I have this same problem...
I flashed the community build (3.5) and can now no longer boot into TWRP. I attempted to flash it this way...
Placed recovery in tools folder (with fastboot and adb etc.) and opened a command window. I typed fastboot flash recovery recovery.img and it flashes fine, but when I boot I get the splash screen and then nothing. What am i doing wrong? I have tried both official and modded TWRP.

Same thing happens with me no modded one works for me too.
In 3.2.6 when we try to flash any other rom it will break the fingreprint scanner dont know why both the update these problems hope the will fix them soon.

[RR Rom 5.7.4 20161113] Bootloop at starting apps

Hi everyone!
I was on RR 5.7.3. Rooted, unlocked bootloader on 9th July when I was on 3.2.0 or something.
I wanted to install the new 5.7.4 and it required some 3.5.5 CB FW files so I followed this guide:
Download list:
Latest ResurrectionRemix ROM (EX kernel)
OpenGapps 6.0 ARM64
OOS 3.5.5-CE Firmware + Modem
Modified TWRP 3.0.2-22 Recovery
Update instructions (from build 20161008)
1) Create a backup
2) Wipe system + cache + dalvik cache
3) Flash ROM + GApps + OOS 3.5.5 FW/Modem
4) Reboot
5) Flash TWRP 3.0.2-22 via Flashify
6) Done.

Installation seems went fine, it installed 143 GAPPS, then it asked me for password to decrypt then it continued installing 28 Google apps (dialer, gnow app etc.). It sometimes vibrates and then again it continues to install those 28 Gapps.
I tried to turn it off: it asks me for password to decrypt, then RR logo is moving, then Optimizing those 28 apps, then "starting apps" and now again the RR logo loading, then optimizing 28 apps, then "starting apps" and again and again in a continuous loop.
Cant' access TWRP obviously, so I decided to boot in fastboot to reinstall twrp:
Code:
sending 'recovery' (18964 KB)...
OKAY [ 0.533s]
writing 'recovery'...
OKAY [ 0.146s]
finished. total time: 0.680s
But again, can't access TWRP. When i choose to boot in recovery it gives me a black screen.
Can anyone help me?

My Problem seems to be similar to yours:
Since flashing CM 14.1 I can't bot into recovery too, get the same black screen. At least I can boot into CM 14.1
Should you find a way to fix the recovery issue, could you tell me how?

I found a solution to have twrp back, but I don't know if it can work for you. Try!
Download TWRP 3.0.2-22
So use fastboot to install twrp, there are hundreds guides on google!
EDIT: If you can boot in CM14 i think you could install TWRP img from Flashify! I think it's easier

Guys, for those of you who has black screens - try to flash the modified TWRP with ADB - it works perfect

Can't install TWRP

I can't get TWRP to install on my phone. I've tried manually fastbooting all three TWRP images that are available from the TWRP website. I tried installing TWRP using the Skipsoft Toolkit. Whatever I do I never get past the TWRP splash screen--no menus ever come up. Since no menus ever come up I can't install the TWRP zip or a custom ROM. I've been trying this for hours and it's driving me crazy. Is there a different procedure to boot into temporary TWRP if you are on the June bootloader? Is there another version of the TWRP image file that I'm missing? Am I supposed to let the TWRP sit there for a really long time? This is driving me completely batty.

Did you downgrade from O?
If that is the case you should flash the stock bootloader and boot.img into both slots on your device and try again

It took way too long but I installed TWRP, flashed DU, installed ElementalEx, rooted with custom Magisk for Pixel and got the phone to pass Safety Net. Everything seems to be working. However, whenever I go into recovery TWRP doesn't seem to be there. I appear to get the stock recovery which I don't understand. I can still boot into temporary TWRP and flash the TWRP zip and flash other zips on my phone but I can't seem to boot directly into TWRP. Is this normal or did I do something wrong somewhere?

If I recall correctly, after flashing any rom you have to flash twrp again before rebooting. Apparently roms flash an img to our recovery partition that looks similar to a modified CWM.

I actually did that. Maybe I was supposed to boot into the rom once, then back into recovery to flash TWRP. There are a lot of different flashing instructions for this phone. It's hard to keep it all straight.

Booting into the rom, going back into temp TWRP and flashing the TWRP zip seems to have worked --TWRP actually stuck this time and I can boot directly into it now. It's a shame Google made the Pixel XL such a headache to flash on.

Pixel 3a XL soft #BRICK - please help

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"

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:

fastboot: error: Command failed

- I tried one other older .img for my phone from official twrp.me website, didn't work
Any Ideas?

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?

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

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

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.

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!
