Question [A13] [RESOLVED] Stuck in loop after upgrade with PixelFlasher - Google Pixel 6a

Hello all,
I have a pixel 6a on A12 rooted with Magisk.
I tried to upgrade to A13 with PixelFlasher with the option to flash all the slots and now I'm stuck in loop.
I tried to use fastboot command to flash again with A13 with no result. I also tried to change the current slot.
The weird thing is that I still have the message that said the bootloader is unlocked...
Any ideas?

You should probably head over to the Pixel Flasher thread so the dev can be aware of this and help you debug.
📳🔥 PixelFlasher, a GUI tool for flashing / updating / rooting / managing Pixel phones.
DESCRIPTION As the name suggests this is an application to flash (update) Pixelâ„¢ phones (possibly all Googleâ„¢ made phones/tablets, YMMV.) PixelFlasher at its core is a UI layer (with bells and whistles) on top of adb / fastboot commands, hence...
forum.xda-developers.com

I just copy my message on the thread of PixelFlasher for the pixel 6a.
While waiting for the developer to answer, does anyone have any leads to unblock the situation?

Thank to badabing2003 I was able to update to A13. It was due to a problem with the version of Android Platform Tools

Unable to install TWRP - Stuck fastboot mode

Phone: OnePlus 7 Pro
Build number: Oxygen OS 10.0.3 GM21BA
Anndroid Version: 10
Model: GM1913
Hi all,
I received yesterday my Oneplus 7 Pro. My objective is to install nethunter fully rooted.
After looking the requirements in the offensive security website i noticed i need 3 things
TWRP
Magisk
DM-Verify
I started with TWRP watching different tutorials and comparing them but they are similar.
- Installed sdk platform tools and Minimal adb/fastboot ( tried both ways )
-unlocked the bootloader and enabled usb debug mode.
- Once i do " fastboot boot twrp.img " everything seems " okay " in the terminal, but the phone becomes stuck in fastboot mode logo image, it never actually boots into the twrp.
In a different tutorial, i replaced the "fastboot boot twrp.img" with " fastboot flash boot twrp.img ". This broke my phone i couldn't start the android or go the recovery mode, i couldn't leave fastboot mode unless to restart or to turn off the phone. I fixed this by " fastboot flash boot boot.img " that i had available in the platform tools folder.
I tried different twrp images:
TWRP 3.3.1-74 Unified Unofficial Pie by mauronofrio
TWRP 3.3.1-70 Unified Unofficial Pie by mauronofrio
twrp-3.3.1-4-guacamole.img
Nothing seems to work, i don't know what else to try or what am i doing wrong.
I've been 8 hours around this so any help would be deeply appreciated.
Kind regards,

I have an almost identical problem to you.
except: my device is GM1910, I had a stock hydrogen OS, which has been converted to oxygen OS.
so far, I have tried twrp-3.3.1-0, 3.3.1-2, 3.3.1-3, 3.3.1-4, on oxygen OS version 10.0.2.GM21AA, 10.0.3.GM21AA, and 10.3.0.GM21AA, all would stuck at the fastboot mode logo screen
Rolling back to a lower version of oxygen OS, including version 9.5.1 and 9.5.7 causes my OP7P in bootloader mode no longer recognized by "fastboot devices", or even by "dmseg" as a usb device.
I received a suggestion of trying the latest TWRP 3.3.1-74 build, which I intend to try later tonight, but got not so optimistic about, seeing that you've experimented with TWRP 3.3.1-74 Unified Unofficial Pie by mauronofrio
One observation I do like to make, is that android 9 is considered as Pie while android 10 was developed from android Q.
since your device is already android 10 at version 10.0.3, should you still use the Pie TWRP build?

Hi OblixioN,
I tried the image with the Q at the end: TWRP 3.3.1-74 Unified Unofficial Q by mauronofrio and it worked. I had no idea what the Q or Pie meant so your information just solved my problem. I assume it will work for you.
Huge thanks!
Thanks - worked for me as well!
Unfortunately I formated before getting to this solution, so rather unnecessary for me, but what I did was getting the unofficial twrp for guacamole here:
h-t-t-p-s://androidfilehost.com/?fid=4349826312261707787
(from this post: https://forum.xda-developers.com/oneplus-7-pro/development/recovery-unofficial-twrp-recovery-t3931322)
Then I booted to fastboot at ran
Code:
fastboot set_active a
fastboot boot .\twrp-3.3.1-75-guacamole-unified-Q-mauronofrio.img
fastboot set_active b
fastboot boot .\twrp-3.3.1-75-guacamole-unified-Q-mauronofrio.img
Now I could boot into twrp, it found all the internal data storage, and I could sideload
Code:
adb sideload .\twrp-installer-3.3.1-4-guacamole.zip
adb sideload .\Magisk-v20.3.zip

It means if you are on Android Q, you need to use the TWRP version that supports Android Q.
Hey, I seem to have the same problem but how do u get it unstuck from the Fastboot Mode so I can try another version of TWRP?

hey there.
So, first of, You restart it by pressing and holding volume up, down and power at the same time for 10+ seconds.
And second, try updating Oxygen OS to its latest version. It works for me now, just unpacked a new OnePlus 7 Pro, didn't work on Android 9, works on Android 10 latest update.

I tried installing a new kernal and after that mine would go directly to bootloader, no matter what I did it went directly to bootload, thankfully fastboot was still active but using boot cmd into anything would fail,, ,I started my msm tool, and rebooted into edl and as soon as a com port became active on the MSM panel I hit start, and it took off running and did it's thing,
I think my issue had two reasons!
1. The boot.img file i used was from the earlier Oxygen update not the version i had just installed.
2. The phone encryption (but i doubt this!)
Anyway since nothing helped i erased the phone and restored it Now it's working again!

[SOLVED] OP7 (GM1900) stuck in fastboot loop, with no access to recovery

Hello,
I'm probably not posting this in the right section, nor the way it should be posted. This is my first post, and I'm sorry if this is the case.
I'll try to provide as much information as I can concerning my problem.
I have an OP7 (GM1900) that was rooted with TWRP recovery and magisk. I upgraded to OOS 10.0.3 through normal system upgrade. As I have done this many times before, I figured it wouldn't be much different. Upgrade done, everything's working but I lost the root and magisk as expected. Went back to fastboot mode, tried to boot to a temporary TWRP image, which failed (only showing fastboot logo in center of the screen). I googled, and ended up flashing both boot_a and boot_b (big mistake I know...)
Now, I'm stuck in a fastboot loop, with no access to recovery whatsoever. Nevertheless, I can still use fastboot and adb to execute command.
I figured I should download a global ROM and flash it again? I'm not sure which one to download since I didn't take note of the build beforehand and have access to nothing right now.
Is there no way to factory reset through fastboot in any way?
Thanks in advance
Update:
I made it worse by trying to flash a ROM I found on internet and totally bricked it to Qualcomm crash dump screen.
NEvertheless, everything is now solved using the MSM tool that can be found here:
https://forum.xda-developers.com/oneplus-7/how-to/unbrick-tool-oneplus-7-msmtool-hydrogen-t3953240
Hopefully, this will help someone with the same problem
This is MSM tool "Hydrogen" Version...
There is msm unbrick tool for OxygenOS (European & International firmware, android 9 & 10)

Thanks a lot ! I'll definitely download this one just in case, it could save the time going back to OOS with a local upgrade.

Root /Magisk error in boot, possibly boot loop.

We received a new 8t and proceeded to do root and unlock on it.
Here is my process and problem.
Unlocked bootloader.
Updated phone to recent version via OTA update.
Downloaded update via Oneplus website.
Extracted payload.bin VIA python.payload dumper.
Moved boot.img to phone and patched it with magisk (select and patch a file)
Moved patched image to PC and ran adb
Fastboot flash boot patched image name.img
rebooted , now its caught in bootloop.
Tried fastboot --set-active=a and it didnt make a difference.
When looking at adb devices it shows the attached phone as unauthorized.
Dont know if this helps
Can get into fastboot
You flashed the OS to the bootloader. Not sure how to help you, man. Maybe try the EDL Tool. That worked for me. Also, always install TWRP and flash magisk zip through TWRP. It's foolproof.
TWRP doesnt work with android 11 or the oneplus 8 as far as I know, last time I looked.
Did a tool and fixed the crashes and bootloop, then followed a youtube video and guide.
Found out I ended up doing a different OS version that didnt match.

TWRP for the 8T works reasonably well. See https://forum.xda-developers.com/t/...recovery-project-8t-kebab-2021-09-04.4302449/

Teclast M40 Pro and Magisk

Hi, I'd like to install Magisk and the various modules, but from what I've read there is not a twrp dedicated, I believe that my device might support the same work done via adb on the M40, the bootloader can be unlock easily from settings developer, therefore, I will understand come enter to fastboot without being too technical, maybe with the shell "Minimal ADB and Fastboot", I accept suggestions, thanks.
I don't know if there's TWRP (or others like it) for the Teclast M40 Pro, in wich case I'd instruct you to get the firmware (specifically system.img and/or boot.img) and either patch boot.img with the magisk app and flash it using fastboot or unpacking system.img and inserting a static su binary under sbin (this is very insecure and feature lacking) or manually installing magisk binaries and configs as it would if it ware done by TWRP, repacking and flashing.
now the former is nice and easy, infact, it's what topjohnwu himself reomends!
the latter... you'll be asking yourself why you even tried

Hi, thanks, I could also try with the tool "Minimal Adb and Fastboot" that I used to flash the recovery. img on Xiaomi Mi 11 Ultra, I could also look for the stock firmware, for now I've only found the one with Android 10 on the HardReset site, the problem is that I can't boot into fastboot mode, even following the instructions by pressing power and volume down and releasing power as soon as the teclast logo appears, but continuing to press volume down, until the recovery mode appears, it doesn't appear and the tablet reboots in safe mode or aeroplane mode...
Oof, sounds like you're S out of L.
with MTK and Quallcomm devices this isn't a problem, they boot into BROM with an EDL USB connection and flash tools just work even with a corrupt bootloader.
never mind unisoc has it too: https://spdflashtool.com/ - it says it's for spreadtrum, but it's the same thing AFAIK
also try holding Vol+Up/Down/both and power for extended periods of time (if it boots android - reboot)
I really appreciate it, yes of course, UNISOC, formerly Spreadtrum, very interesting tool, so now (I have not done anything yet I'm just reading) I can download the drivers spd and with the tool possibly install boot.img modified by Magisk, although I do not know, exactly how to do it, I will learn! Thanks

Good morning, I've tried almost all the Hovatek methods within my reach, but with android 11 it's impossible to patch recovery.img because it doesn't exist in the stock rom, patching the boot.img is useless, editing the vbmeta-sign.img I haven't figured out how to do yet, so I'm back to square one. The only thing could be to downgrade with the Teclast M40 rom that is android 10, but I do not know if Spd Upgrade would allow me to flash with that rom, what do you think?
Hi,
Do you find a solution to root the M40 pro ?
Thanks

Question How to unbrick One Plus Nord CE 2 Lite ?

I have bricked this device (One Plus Nord CE 2 Lite) by flashing the unofficial twrp image for this device. Device bootloops in TWRP.
Previously, I had succesfully unlocked the bootloader and rooted this device by flashing the patched magisk boot.img by following the method mentioned in this post (https://forum.xda-developers.com/t/rooting-oneplus-nord-2-ce-lite.4500297/)
How to restore the factory image and recover from this?
Any help is appreciated.
Thanks
...reboot to fastboot, flash the original boot and vbmeta and you're done ...maybe you have to change back the slot, but it's almost impossible to brick the device
...don't mess around with "Recovery" ...this device has already the newest partitioning system and there is no recovery partition
best regards
I messed up by flashing the wrong twrp image made. (Device was stuck on 1+ logo screen)
Thanks to your post i was able to rescue this device.
I used Oxygen Updater App, payload-dumper-gui and minimal adb fastboot.
Flashed boot and vbmeta with stock img files.
Restarting the device now will boot into fastboot mode.
Changing slots helped a lot.
(fastboot set-active=a/b)
After that, Device booted normally into OS.
... you're very welcome, Sir ...but really, don't mess around with "old school" recovery systems ...they are not needed anymore and furthermore they can't handle the "dynamic super partitioning" ...and again: nobody needs them after the year 2015 anymore
...best regards

Hey can you help me pls, I am in the exact same situation as you but I can't get the stock img files, whenever I use payload-dumper it just gives me system.img and nothing else, could you maybe share your img files ?
Edit: I manged to get some files but still not the boot.img, I don't undestand why it just refuses to give them to me, I redownloaded everything at least 3 times...
Use Payload-Dumper-GUI instead of Payload-Dumper-Go
Hey @NickR01 if possible can you send me an boot.img and vbmeta
I don’t have windows pc so can’t use Payload-Dumper
It will also help future users to unbrick device.

@vikas_anakin I have files for eu variant, can't help you there bud. If flashed it can mess up your device.
If you are stuck with payload.bin extraction... try it with an android device.
Here's the tool for Android.
Payload-Dumper-Android
Here's the guide for it.
XDA Guide
Newb Guide
Follow the guide and download this app to extract the .bin file
Termux App: Termux Github
After the extraction, type fastboot (pc required) commands to flash and change current active slots from A to B if it's stuck in bootloop after flashing.
I hope this helps you recover your device.

Extracting the payload.bin is not an issue, The issue is I don't have stock firmware.
I used https://www.getdroidtips.com/oneplus-nord-ce-2-lite-5g-firmware-flash-file/ but my wifi and Bluetooth are not working after installing it.
Do you have any suggestions on how can i resolve these issues?
@vikas_anakin Download authentic firmware from this app. Files are pulled from OnePlus servers.
Google Playstore: Oxygen Updater
Oxygen Updater Settings -> Enable Advanced Mode
Select device region.
Latest update for holi is CPH2381_11_A.13 as of now.
I extracted the images from the payload.bin found in the Oxygen Updater file (that I had actually successfully used to update my device) and flashed 2 partitions:
fastboot flash vbmeta vbmeta.img
fastboot flash boot boot.img
I then rebooted and now it's stuck in a boot loop & I can't even access fastboot anymore. Can someone please help?
Thanks
EDIT:
I managed to access fastboot & flash the rest of the partitions to fix it.

Or else you can extract img files from the oneplus rom file.
and flash them using fastboot.
Okay thank you for the reply, would you be able to point me to a official img file ? Or maybe someone has one extracted I could use please? I have looked online, but the ones I have gotten don't seem to work. I have also looked on the oneplus website for an official img but I could not find one.
So after a little more research, I can use another android device with the app Oxygen updater, download the full img.... So I am currently doing that and then ill try use fastboot or twrp to flash. Just wanted to spread info incase anyone else is having issues getting latest official roms for this device.
Hey guys, i have bricked my Oneplus Nord ce 2 lite 5g (Cph2381)
I tried using the fastboot enhance tool to flash a payload.bin file i thought was the right one for the device ..the device went to blackscreen..ive tried switching it on but its not working..ive done alittle research and found out that i should use an msm tool to force flash the initial stock firmware so that it can boot up ...problem is i cant seem to find the right msm tool for Oneplus nord ce 2 lite 5g , which msm tool can i use ? help please

Hey man, I would suggest not going with msm tool or anything.
Just download the latest update file of your device using oneplus updater app, or you can ask for the file if some of your friends has the same device.
use this tool to extract payload files https://github.com/vm03/payload_dumper
Now you can follow the same procedure as here https://forum.xda-developers.com/t/...ock-oxygenos-firmware-on-oneplus-10r.4465077/
