Pixel Bootloop (Bootloader unlocked) - Google Pixel Questions & Answers

So I have been trying to flash the Pixel Factory Image, I have used the most recent SDK Platform Tools and I still can't get past the boot loop. I also have tried to flash the TWRP recovery but I am getting this:
Code:
C:\Users\MyName\Documents\Pixel\minimal_adb_fastboot_1.4.3_portable>fastboot flash recovery twrp-3.3.0-0-sailfish.img
target reported max download size of 536870912 bytes
sending 'recovery' (31000 KB)...
OKAY [ 0.828s]
writing 'recovery'...
(bootloader) Flashing active slot "_b"
FAILED (remote: partition [recovery] doesn't exist)
finished. total time: 0.938s
I have even tried but the bootloop is still there:
Code:
PS C:\Users\MyName\Documents\Pixel\minimal_adb_fastboot_1.4.3_portable> ./fastboot boot twrp-3.3.0-0-sailfish.img
downloading 'boot.img'...
OKAY [ 0.727s]
booting...
OKAY [ 1.010s]
finished. total time: 1.740s

There are a couple things wrong here:
Pixels don't have a recovery partition, everything happens in the boot one (root, twrp, custom kernel)
The first command in the first code block you wrote is wrong because the recovery partition is not there. In case you wanna flash a stock boot image, maybe for recover your device faulty kernel/twrp etc, without have to reflash the whole rom, the command should be "fastboot flash boot boot.img"
The command you sent in the second code block (./fastboot boot twrp-3.3.0-0-sailfish.img) in fact is correct because you just boot the twrp image (= no errors).
But when you wanna flash the recovery, you have to boot the twrp img and when it booted you have to flash the twrp.zip that you can download from the official site from the twrp screen, not the .img
Hope this helps

I'll add that you should also use the official platform-tools downloaded from Google. The minimal (and other alternatives) can give you problems when trying to flash.
The latest platform-tools is here. Note that Google hasn't updated the changelog, and the latest version is actually 28.0.3, not 28.0.2.
For TWRP, you need both the latest .img and .zip files from here, and transfer the .zip file to the Pixel. Use the boot command to boot from the .img, then from within the temporarily-booted TWRP install the .zip file.

Can't enter TWRP

I wanted to flash the latest update of RR7 but when i tried to get into the recovery the phone would reboot and show the twrp starting screen and then it would reboot again and start normally. I figured something must have gone wrong and reflashed twrp from my pc, however the issue persists. Flashify doesn't work either. So aside from a clean install, is there a workaround?

You can try to boot directly into twrp with "fastboot boot TWRP.img"

Just tried it, same thing happens i can see the twrp starting screen but i can get to the main menu.
EDIT.
Changed the twrp version to an older one. No results, tried both flashing and booting from fastboot.

Then something is really wrong with your internal memory. Because that boot command in the post above does not use TWRP installed on your phone, it's a "temporary" TWRP booted from your PC folder.
Even if you've never installed TWRP on your phone (still have stock recovery) you can still boot to TWRP for a one-time/one-off session by using those commands. Do whatever you want, like install SuperSu, and when you reboot, you'll still have stock recovery!

XT1039 softbricked, any help or suggestions appreciated

Hello,
Edit: Don't know how or why, but after a couple of more tries I was able to boot the recovery directly and flash the rom. So everything is working fine right now. Admin/mod, would you like to close this thread? Thank you
For some reason I wanted to flash a new rom on my XT1039. In the process I screwed up and got it softbricked. I already had a look at the thread started by alfread56 and although the situation seems quite similar, the offered solutions didn't work out for me.
Right now my phone doens't have any rom installed. Flashing twrp with fastboot suggest everything works allright (using a linux system by the way):
fastboot flash recovery recovery.img
(bootloader) has-slot:recovery: not found
target reported max download size of 536870912 bytes
sending 'recovery' (8314 KB)...
OKAY [ 0.295s]
writing 'recovery'...
OKAY [ 0.303s]
finished. total time: 0.598s
After the reboot and holding the buttons for recovery mode I still get the stock recovery screen. When I select recovery in this menu, the phone shuts down. Because I know holding the recovery buttons on reboot takes some timing, I have redone the procedure of flashing twrp and holding the buttons numerous times. But it never went to the twrp recovery.
Then I tried to boot the twrp image directly with
$ fastboot boot recovery.img
downloading 'boot.img'...
OKAY [ 0.290s]
booting...
OKAY [ 0.230s]
finished. total time: 0.520s
Here I made a mistake: I have also flashed the boot partition with the twrp image with fastboot flash boot recovery.img (don't know how much of problem this is).
Booting up the TWRP image works fine. Then I've wiped dalvik, cache, data, internal storage and after several runs also deleted system by accident, and factory reset. When trying to flash the lineage zip everything works out fine for about 1 second, then the screen flashes en the phone is back in the TWRP screen. Too quick for me to see what the output is, but I do see there are not red marked lines (no errors)
I have tried it with several different ROMS (al checked), with several versions of TWRP and with fastboot and mfastboot. Does anybody know a solution on how to get twrp recovery working on my phone, or why I can't flash a rom when I boot twrp directly? Any help is appreciated!
Thank you in advance.

Root: Stuck at "Your device is booting now"

Hello! I tried to root my Honor 6x (BLN-L21, EMUI 5.0) following the instructions there:
cyberkey.in/how-to-root-honor-6x-100-working/
The bootloader was successfully unlocked.
But when I tried to flash TWRP the process failed and now my phone is stuck on boot :
"Your device has been unlocked and can't be trusted [...] Your device is booting now."
I can get access to recovery and fastboot. I wiped the cache and tried a factory reset but nothing changed, my system won't start and I don't know what to do.
Please help!
if you have the boot backup then restore it.

I don't have any backup. Is there a way to just reset everything? Also I don't know how to connect to the phone anymore since adb won't find the device.
if you cannot find the boot.img
just do a rollback bro

I think that I flashed the wrong files in "boot" and "recovery". Please tell me which files I should flash there.
I used the commands:
.\fastboot flash boot twrp.img
.\fastboot flash recovery twrp.img

The guide from "cyberkey.in/how-to-root-honor-6x-100-working/" is simply wrong when it comes to flashing the twrp recovery. If you really followed this guide completely then you flashed the recovery to the boot partition.
Use "fastboot flash recovery twrp.img" to flash the recovery.
You will still have to flash the boot image to your boot partition then (fastboot flash boot boot.img).

Use fastboot flash recovery twrpname.img to flash the recovery
Ok so basically I need to flash the boot image. However I don't know where to find the stock boot image. I downloaded the so-called "full version" of the stock firmware that I found here: boycracked.com/2017/07/20/official-huawei-honor-6x-bln-l21-berlin-l21-stock-rom-firmware/
However there was no boot.img file inside.
If you could direct me to the proper stock boot.img or send me one, that would greatly help. I had EMUI 5.0 with Nougat 7.0 I believe, phone version BLN-L21.

Thanks. I successfully updated boot.img and and recovery.img, but system won't load, so I might have imported from the wrong STOCK version.
I tried to reinstall a stock ROM using:
fastboot flash system system.img
But I got this error message:

sending sparse 'system' (444686 KB)...
OKAY [ 12.901s]

Then I tried to erase the system file with "erase system" and got this error:

I guess that the only option now is to install the files on an external SD card?

I recommend you to download firmware files only from the official honor website or by using the huawei firmware finder(https://forum.xda-developers.com/tools/general/huawei-firmware-finder-team-mt-t3469146)
In this case try to use huawei firmware finder to get the right stock version for your phone. Download these two files: e.g. update.zip & update_full_BLN-L21_hw_eu.zip.
Export the following image files: recovery, system, boot and cust.
The try to flash them:
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash cust cust.img
fastboot flash recovery recovery.img
If flashing a partition via fastboot fails then it is usually because it's the wrong image or just not made for your phone.
Thank you guys, you saved my phone! I eventually managed to flash the files from Nougat update for European Honor 6X BLN-L21C432B360 that I found there: stechguide.com/honor-6x-b360-nougat-update/
Now the phone is working fine.

Hello, could you be more specific about your problem? I'll be able to help you.
Brief Explanation:
From the screen on which you're stuck, press and hold power button for about 10 seconds to forcibly restart your device. when you see the same screen again, immediately press and hold volume up button(for about 3 seconds) to boot to eRecovery.
> Choose shut down option on eRecovery. press and hold vol down button and insert the charging cable to boot to fastboot.
> Press and hold power and volume up button to boot to recovery. (You could do this even from fastboot screen and the screen you're stuck at).

Help me unbrick my Honor 8

Well guys, I think I did it. I think I really did brick my Honor 8.
Phone details: New Honor 8, Model is FRD-AL10.
It came with the Chinese ROM, locked. What I did was to unlock it with DC unlocker, flash TWRP as custom recovery and root it.
Later, I had some problems with installing Open Gapps so I decided that I will flash a custom ROM unto it. What I chose was this RROS. I followed all of the instructions, made sure my EMUI was up to date, deleted all of my fingerprints (although I did not disable the PIN lock). I performed a factory reset using TWRP, flashed RROS and started facing errors.
Trying to power up the phone I found out it was going into bootloop, not able to start up. Only recovery available was not TWRP, but the default Huawei eRecovery, that lets you restore the phone using the Wi-Fi to download the needed files. Panicking for my new phone, I tried to restore my phone this way, only when it completed the download it failed restoring.
I have tried to unbrick my phone using the Honor 8 Multi-Tool: flashing BOOT.img, CUST.img, Recovery, USERDATA.img and SYSTEM.img. The firmware I downloaded and extracted UPDATE.app from is this: FRD-AL10_C00B135_Firmware_China_Nonspecific_Android 6.0_EMUI 4.1_05013LBP.zip.
The Multi-Tool's log is this:
Code:
12:51:55: All images are found, everything is ready for the unbricking process.
12:52:01: Unbricking started. Your computer may freezes during the process.

I also tried to flash UPDATE.app using a microSD card and the Volume up+Volume down+Power combination, but it fails after 5%, Saying:
Code:
Software install failed!
Incompatibility with current version.
Please download the correct update package.
So either my phone is completely dead, or I am missing something here.
Can anyone help me restore my phone to normal function?
you need to find the rollback package, you had android 7 but you're trying to flash android 6

Cannot flash TWRP with latest OTA (5.4)?

I'm trying to obtain root on a Shield K1 that has the latest ota update (5.4).
I've unlocked the bootloader, but the latest TWRP just won't flash, says OK and writes to recovery, but same stock recovery stays there.
Do I need to use an older developer image, one that was released prior to the latest TWRP?
This is what the terminal is giving me:
Code:
[[email protected] tablet ]$ sudo fastboot flash recovery twrp-3.2.1-0-shieldtablet.img
target reported max download size of 100663296 bytes
sending 'recovery' (12426 KB)...
OKAY [ 0.487s]

OKAY [ 0.506s]
finished. total time: 0.993s
Then, when I reboot to recovery, I get a dead robot with a little ? & "No command"
EDIT: OK, I fixed it, by using "fastboot boot twrp.img" and then installing lineage and then installing twrp
I didn't know that you could boot an image without installing it that's really good to know.
So that's a workaround.
I could just compile a new TWRP but that would take effort

You definitely don't need to do that. I have a K1 on 5.4, and TWRP works fine. Although I did already have TWRP installed before flashing 5.4. So not sure if that makes a difference.
Try fastboot erase cache, and flash a different TWRP build (like a build or 2 older such as 3.1.1-0).
I fixed this already
