Bootlooping on dead Android guy after failed installation, help! - Nexus 6P Q&A, Help & Troubleshooting

I had my phone rooted on old Oreo version and wanted to reinstall the latest factory image. While I was doing this my laptop got a BSOD and the installation didn't fully finish. I redid the install but now my phone is in a bootloop. It will go past the Google logo but afterwards will loop on the dead Android guy with the ''No command'' message, same happens when I try to enter recovery mode. Is there something I can do?

I would flash TWRP and try wiping all including internal. Sounds like one of the partions is corrupted. You could do it with fastboot in bootloader mode but not sure of the commands.

You're probably not used to the stock recovery. The no command droid is normal. Watch this video, and see if you can get to recovery or bootloader.

[Q] Stuck in recovery boot loop...?

While using the PA Updater app to upgrade my rom, the app attempted to reboot into recovery to run an openrecovery script. While doing this, I believe it set my "reboot mode flag" to recovery.
The tablet boots with the Google screen and then shows the TWRP splash (I'm on version 2.6.0.0), then it reboots and starts again.
I am able to get to the bootloader, but even if I press start or recovery mode it reenters the boot loop trying to get into recovery. In the bootloader was where I saw the reboot mode flag set to recovery. Is there a way to use fastboot to remove that or am I just going to have to do a wipe with fastboot?
It happened to me once. I pushed the power button for 60 seconds as it supposed to do a kind of battery pull, and it worked.

I've done this twice to my nexus now and I think I found a reliable way to restore to running condition. YMMV
1)Boot the nexus into fastboot (power and both volume keys) when you power up.
2)Attach your usb cable from the PC (or MAC I guess, dont have one to try)
3)start WUG Nexxus Root Toolkit. 'Launch' advanced utilities.
4)Test your fastboot with Quick tools. check the button at Fastboot-Bootloader and click 'List Devices' if the box that pops up is empty then fastboot isn't working (I can't help you there and it must be working to continue).
5)If fastboot shows a device then go to "Boot Temporary" and click 'Custom Recovery'.
6)I selected 'Touch TWRP' but CMW may work as well. This will reboot you into (temp)TWRP and from there you can force a reboot that will reset the 'Recovery' flag that has locked your bootloader.
7)Give it a few minutes (be patient for 5 minutes) and hopefully you reboot to where you were prior to this mess.
Long time lurker and couldn't fix my fails without everyone here.
Thanks to all.

I had the same thing happen to me (though i updated from stock 4.4 to 4.4.2 [and i had twrp installed]). I tried reflashing to stock recovery and a few other things but same problem, it kept booting me into stock recovery. I know this is going to sound crazy, even stupid, but just letting it sit there for 5 minutes (at the stock recovery screen) let it work... I was searching for more things to try and it just started booting.... Checking the bootloader again showed the reboot mode flag set to none.

I guess mine worked because I was still on stock bootloader and adding TWRP was an important key but the 5 minutes seems to be the solution after all the rest.
recovery boot loop:- Is coz, one of your partitions would be facing problems while mounting.. So Wipe the Partition and Format it with Ext-2 file format. and reboot the Mobile. Then it'll stops rebooting.
Do you have a Samsung device?
Be warned - there is no such thing as fastboot mode for most Samsung Galaxy devices - you'll be wasting your time doing this and typing "fastboot devices" for many hours!
If you have problems with your recovery, it works to just reflash the CF-autoroot kit, which happens to flash the cache partition too. My problem was similar to the OP's - a bootloop with TWRP's obviously buggy OpenRecoveryScript, which was installing a ZIP file over and over again.
If you flash the CF-autoroot specific to your device, TWRP will be gone, but the phone will boot normally again - with all your data on it - hooray!
Then you install TWRP or CWM recovery as you did originally.
Stay away from OpenRecoveryScripts! I'll be installing a ZIP file in the traditional, manual way from now on, from an external SD card so I can remove the card if I get another TWRP boot loop.

Needing some help to fix my recovery

I'm having a problem getting into my recovery. I have the D800. It started out I sideloaded cwr thru twrp. And it said it flashed fine. I selected to reboot back into recovery and got a fastboot error. So i tried just rebooting and couldnt get passed the splash image. So I did the whole flash stock firmware. And after i got done with that, I think I did the ota update, And I got my phone rerooted. But still no recovery, it loads to a black screen and my pc says I have to format drives from like u-z but one has a folder titled image with these files. I've tried adb pusing and flashy and nothin,.Please help
never mind I got it fixed I think. Please delete post

Brick and Restart Loop no Download

Hi,
I was on a rooted android 4.4.2 official, when i tried to install custom recovery using Flashify.
https://play.google.com/store/apps/details?id=com.cgollner.flashify
There was the Secure booting error and booted normaly.I found out that this was not possible so i quit.
Today a got an update from LG so i installed it. The phone rebooted giving the Secure booting error, and it stayed black screen.
Googling i found this tread
http://forum.xda-developers.com/showthread.php?t=2582142
I folowed it but i thought since my phone had problem with it's recovery, just flashing the recovery.img would be ok.
I restarted the phone bat it would not start. It desplays the lg logo restarts, lg logo restarts.
I can boot the recovery but it does not work. When i press recover it just restarts.
I cant boot download mode or anything else, i have been googling the hole day.
I would apricciate your help. It is a one month old phone.....
Thanks

are u stuck in cmw recovery??
Stock recovery.... :/
Sent from my GT-I9100 using XDA Free mobile app
Same Problem here! Exact Same
Also having this issue, stuck in the secure boot loop, can't get to download mode.
Im exactly the same - im stuck in TWRP and cant boot into Download mode at all - just get the LG Bootscreen then straight into TWRP Recovery no matter what i do
Did we all except some kind of update from LG........ i wonder if this the link here and is now a common problem?
Mine was this and i thought it was just an app update for the stock apps and now im stuck big time
Any luck guys or solutions then please post here so we can keep it together and help each other!
Yeah I got an OTA update for my D803-Bell model, upon restart entered the secure boot error loop.
Sounds like, via this thread that it's commonly happening to people who had TWRP or CWM (or even aborted / possibly never completed installs like me) got nailed.
As per that thread, and everything else, I've tried every option possible -- no download mode. Recovery mode doesn't restore anything, just resterts to lg logo -> secure boot error -> black screen. Shows as QSHSUSB_BULK in windows/linux, and I can see those 25 partitions in linux (but reflashing openrecoverytwrp__.img over the recovery partition didn't help. I'm waiting to find out how I can make my own copies of those various partitions listed, from another D803-Bell model I have access to. All the D803 .img files on those links in that thread, appear to not contain D803 Bell stuff, just Telus, Rogers, etc... so I'll likely have to source my own.
I just took a shot in the dark recommended by a friend -- and fixed my phone.
I zeroed out the 'fota' partition on the phone. As seen in this thread ; http://forum.xda-developers.com/showthread.php?t=2451696
Just did a dd if=/dev/zero overtop of the fota partition, which was 25 for me from my linux box. One quick power cycle later, and I'm fully functional again, and the OTA update that killed me is still showing as available again.

SM-T580 Softbricked, Currently on reboot loop, can't flash any stock firmware

Here's what happened:
1. flashed wrong twrp version for 8.1 oreo, used correct CF-auto root
- tablet booted to stock recovery screen a few times but i figured it was part of the process so I just rebooted
-ended up getting a failed identification verification
-i know the auto root worked because my warranty is void :silly:
2. reset my tablet from the failed verification screen
-eventually got myself to a blue erasing screen loop
-flashed twrp again and got myself to a point where booting into recovery resulted in glitchy lines
3. attempted to factory reset from reboot with adp
-not sure if it worked tbh
-also tried to reboot to recovery screen and that didn't really do anything
4. found and installed the proper version of twrp (3.2.3-4)
-now stuck in feedback loop that occasionally shows the twerp screen so i know something's right
-won't boot to recovery screen but will boot to download page
-doesn't show up in adp devices during this loop
-- have CONTINUOUSLY tried flashing firmware (I've tried 6.0, 7.0?, and 8.1) none of them have worked, sporting some variant of secure check fail (PIT, bootloader, or RADIO)
-- have tried the mod here but it fails after param.bin and i can't use it directly after auto root without rebooting because it gets stuck on setup connection
-- most likely not a hardware problem because i had this tablet for basically a day before i did this to myself
--OEM is unlocked, not that i could change it even if it wasn't
---is there anything that anyone would recommend trying before i take this to geek squad (who may not help me but i'm still going to try) or should i just cry myself to sleep over wasting $300 :crying::crying:

I can boot to download mode but i can't boot to recovery mode after flashing twrp. When I try I just get stuck in a reboot loop, so I can't try to boot to recovery from adp either.

If you can flash twrp then not booting to twrp must be pilot error.
It MUST be done immediately after flashing in odin.

Stuck in black screen, can't boot into fastboot mode

I got my Mi A1 today and it came with Android 7 installed, so I decided to install LOS. I unlocked the bootloader and then I booted into TWRP using fastboot (I didn't flash it), it gave that "system is read-only" warning. I tried to reboot to system without doing anything and it was stuck in a boot loop. Then I booted into TWRP again and flashed LOS sucessfully. When I tried to flash gapps, however, it failed claiming I was still running Android 7. I rebooted and it booted sucessfully into LOS, but that was the last time the phone ever booted. Now it shows the unlocked bootloader message and then gets stuck in a blinking black screen. I can't even boot into recovery or fastboot anymore.

It seems you will have to flash stock ROM using Mi Flash (no idea how to use it so search it) and, once is done, flash LOS again.

I somehow managed to get to fastboot and then I used MiFlash to flash the stock rom. I'm back to the bootloop, which is an improvement, because at least I can consistently get into recovery and fastboot.
The phone got stuck in that black screen after I tried to flash LOS, should I actually do it again?
EDIT: I flashed the stock rom a second time and it's working again. I don't know why, but I'll take it.

Update to stock Pie before trying to reinstall LOS again. Hope this time works.

You should install 1.0.8.0firmware first before install 9 ROM!?
