Hello all,
I have been using my Pixel 4 XL for years, and all of a sudden it shut down, and now it keeps being stuck in a booting loop.
I get to Google's logo and the loading animation ... and then it turns black, and starts all over, in a loop.
I am able to access the bootloader and recovery mode.
I tried a complete wipe through recovery mode, didn't change anything.
I wanted to flash original images, but the bootloader is locked and I haven't found any way to unlock it without going through the phone settings (which doesn't boot anymore).
All fastboot flashing related commands fail stating my device is locked.
Would you have any suggestion ?
Anything I should try before considering my device is completely dead ?
Thanks in advance

Try sideloading an OTA image. You can do that with a locked bootloader.
Thanks Lughnasadh
I've tried multiple times, and the process fails randomly, at different percentages ...
The phone suddenly reboots and the laptop displays " adb: failed to read command: No error"
The weird thing is it doesn't reboot and can stay up for super long while on the bootloader.
With a locked bootloader the rescue OTA (full OTA image flashed via adb) is all you have. I would try a different data cable (A-to-C) first and then move to a different computer. Make sure the new PC is running the latest adb/fastboot binaries. This is why I unlock the bootloader on every Pixel in my family. Even though they will never root the phone, if the fit hits the shan you have many more options. BTW, I just traded in my son's P4XL and got $285 trade-in on a 6a. Net cost was less than $150. The deal just ended but will likely come back again. Same deal was offered earlier but included a pair of first-gen earbuds. Wish you luck on getting your old phone working. The P4XL is still my primary phone and is still working well.

My out of the box Nexus 6 is now stuck looping on and off at the Google boot screen after it tried to install the system update.
I've used the toolkit 1.9.8 to go back to stock. It goes thru the steps appearing to show OKAY and finished at each step. It never reboots the phone at the end. I try to force reboot after waiting for several minutes and it still boot loops. I try again the process again and sometimes it loops and a few times it actually starts up to the welcome screen. However, if I try to root or update recovery (using the toolkit), I get the boot looping again.
Did google bork my phone during a failed update? Is there anything else I can do to completely restore the phone? I've also downloaded the images on google and flashed---same boot loop.
Ultimately, my phone is now booting up to the welcome screen as expected and shows LRX21O. BUT, if I try to do anything (root or recovery), boot loop results again.
(I was able to unlock the phone and know about the usb debug and OEM unlock settings in dev menu, fyi).
Hi
I have an AT&T XT1058 with locked bootloader, on 4.4.4
I tried to rest it to factory, but it got stuck on 'Erasing...' (with the little droid) for more than an hour, so I reset it.
Since then it won't boot, only keep stuck on 'Erasing...'. I've tried reflashing it with ATT_XT1058_4.4.4-KXA21.12-L1.26_CFC_1FF both using RSD lite and manually using mfastboot, but no luck - the phone still boots to 'Erasing...' and sometimes after that to the recovery.
I didn't find anything in relevant threads. Does anyone have an idea?
Selecting 'Factory' in the bootloader seemed to fix it.
It is more comlicated than that
The phone does boot after selecting 'factory' in bootloader, but only once - turning the phone off and on again brings it back to its 'erasing...' state. Besides that the phone seems to not be able to charge the battery

Were you able to get this resolved? I have a xt1095 doing the same thing when I flash a stock recovery. Just shows the android guy and just stuck at erasing... When I flash TWRP it doesn't get stuck at the "erasing..." anymore but just boots straight into TWRP.
Sorry for the late response, I missed the notification on your message.
I wasn't able to fix it, returned it to motorola.
Hey, sorry to bother everyone with another bootloop thread by I just can't for the life of me work out if I'm doing something wrong, or my device is more of a dud than usual.
So got the phone yesterday, did some ota updates ended up in a bootloop.
Now at this point my bootloader wasn't unlockable as I hadn't enabled it in developer settings.
By some miracle it managed to boot itself back into the OS after an hour of fiddling and i decided to enable the option in developer settings.
Now I've unlocked the boot loader and got all the flashing related fastboot commands working i've
Flashed a stock image using the miflash tool, seems to succeed but then on reb but once it's done i'm still in a boot loop!
I've been able to boot into twrp a few times (though most of the time I can't and am still in a bootloop)
Tried flashing a custom rom, but I always seem to be in a boot loop after attempting that.
Throughout the last few hours i've also managed to hit the os a couple of times but it seems very easy to accidently put it back in a bootloop.
If anyone has advice of something to try, that would be great.
(was trying stock image version 10.0.9.0, going to try and go back to stock Oreo)

Try some custom kernel, or patched boot img
I've found in 3 Mi A2 phones (mine, gf and family member) the bootloop is actually easy to overcome pretty quickly by waiting. I got the bootloop with all of them when they updated to two updates from what they came with no bootloader unlocked or flashing.
In each case I plugged the phone in, and left it rapidly turning on and off. Make sure to watch the phone, it will possibly come up with an error screen a couple of times so just press to continue trying to boot (also a glitched screen maybe that says fastboot with no options, press the volume control and the option to continue appears again). After a minute or two the phone will get to the normal charging screen, at that point the bootloop is fixed just hold power button until it starts.
Longest I had to wait was coming up to 2m, one time less than 30s.

Yeah, A2 have A/B partition and if update is faulty and the phone ends in bootloop, after a few failed boots, it will boot from other partition.

I think something along these lines is how i managed to get into the phone the first time and enable oem unlocking.
After a lot of playing around I was able to get the phone to boot by flashing the latest Oreo image (9.6.16)
After that tried going to a pie image again from fast-boot image (10.0.8) and once again ended up in a boot loop.
Lastly I flashed a fast-boot image of the latest ota (10.0.10) and managed to boot in.
So phone is at least all working now. Thanks for everyones help. Just hope the next ota doesn't bootloop the phone again.
@NotOverHere: When the phone finally does boot up, do you find it's stable and reboots are fine after that?

Plss post the link of 10.0.10
Hey all
I'm updating to May Updates using This Guide and then plan to update to June.
Problem is that I send 'adb reboot recovery' and the phone restarts, shows the start up screen, then the Google logo, then restarts without ever showing the android logo.
I can get into Fastboot mode and try to select recovery with the volume and power, but again, it boots to the google logo, then back to the unlock warning and boots to my lock screen, never going to the android logo.
Ideas?

Make sure you are using the latest adb/fastboot binaries (April, 2020). Flash the stock boot.img from the same guide. You will be unrooted but will be able to boot into System. Now read up on how to patch your own boot.img, it really is very simple. Personally I do not depend on, wait on, or use OTA's. The full image is available the first Monday of every month, and I extract/patch the boot.img from it. The whole operation including rooting takes just a few minutes. It's just one extra step. Once you get the pattern down it can be done very quickly, consistently and you're not depending on someone else's files. If you are bound and determined to use this method, you should seek out more guidance in the tutorial thread itself. Good luck. :good:
Hello everyone, my phone (Redmi Note 9 merlin) has started bootlooping. It can boot to fastboot, but is unable to boot to recovery (either through fastboot reboot recovery or Vol + during boot). I have tried using SP Flash Tool using the hard brick tutorial and it still bootloops even though all steps proceed normally. I have tried to flash both old and new versions of MIUI, and all of them stlil do not work.
My bootloader is still locked so I am unable to use fastboot or other tools (like MiFlashBoot) on it.
Trying to unlock it from Mi Unlock gives me an error (1004). It seems to be due to the SIM card not being the same but I have not touched the SIM card since I got the phone.
In the past I have used MiPhoneAssistant to restore it as I could access recovery mode, but now even recovery mode is out of my reach.
What should I do now?
Thanks for your time.
Do you know what could cause the boot looping? The most common one is after installing a new version of MIUI.
I'm not sure how it happened, but if it is caused by a MIUI update, how would I go about fixing it?
If it has a locked bootloader and it's still in a warranty. Visit the store where you bought it from and claim the phone has stopped working and started bootlooping.
