Boot Loop - Help

Just got my HTC One M9 (Canadian on Bell today).
I go home to start getting all my apps and data back on and the phone reboots itself, half way through the reboot, it reboots all over again. This just keeps going on creating a massive bootloop.
I can get into flashboot mode. But none of the options in there seem to help.
I've tried flashing the RUU but am S-ON so that was no good.
I've tried everything I can think of and got nowhere.
Any help is greatly appreacited

Have you tried going into recovery and doing a factory reset?

The phone won't even boot into recovery. Just keeps boot looping when selecting that too.

if you have a costume recovery hold Volume UP and DOWN and POWER button at the same time, it should take you to the boot loader there boot to recovery

No custom recovery.
Phone is completely stock.

maybe the power button is stuck or something any updates?

Thought about that idea.
Brought it back to bell and traded it for another. No issues yet...

Bricked?

Hey Guys,
I think I bricked my HTC 10...
I installed stock system img, after deleting everything...
then I relocked the phone... (fastboot oem lock)
now everytime when it starts, it tries to get in recovery but after 1 secound it restarts ... so Bootloader loop..
Actually I was very sick and don't know why I locked it ... Never work on a phone when you are sick
Any Ideas? I would sell it on ebay as replacement for others

As long as it powers on it's not bricked. Can you get in to download mode?

you are still unlocked?
got twrp recovery installed?
just flash a rom, it should boot. If you are relocked and have no TWRP installed, only a RUU will help, you need to be able to access download mode though.

plz help phone bricked
so I have kinda the same problem only I have never touched the phone its locked and on a power up loop plz help

[SOLVED] Android Pixel XL Boot Loop, Never Seen Before

My XL is stuck in a boot loop that I haven't found described anywhere. It begins with the bootloader unlocked warning screen then goes to the white "Google" boot screen, but within one second the screen goes black, waits about 10 seconds and runs through that cycle again. It also randomly (it seems) does the "Writing to EX4 file" screen before the bootloader unlocked warning screen.
It will cycle through this sequence forever if it's plugged in but when not plugged in it will seemingly power off after a random number of cycles. However, powering on does not require holding down the power button - it jumps directly to the beginning of the cycle, sometimes at the bootloader unlocked screen and sometimes at the EX4 screen.
At no point does my Windows 10 PC show the phone as being attached when plugged in to USB. Also, no combination or duration of the phone's physical buttons affect this in any way.
I was following the steps in this article and had just performed the second-last line in the post, "Reboot into the installed recovery." That's when the cycle started. Prior to the step "In TWRP, install twrp.zip" everything was working correctly, though I hadn't rooted yet, of course. I didn't reboot normally in between those two steps, so I can't say which of them caused the problem.
I'm running Android Update, 7.1.2 N2G47E and had been before beginning the procedure. It came from the OTA update and had unrooted the phone from the previous version.
Any and all help will be rewarded with 137 Antique, Pre-Web Internet Points and The Thanks of a Grateful Nation™.

I would fastboot latest factory image.
Just hold vol- when a reboot comes it will go into bootloader.

Sounds like you were coming from the April 2017 update to the May 2017 OTA update. The May update included a new bootloader which performs additional verification on the boot image. I suspect that when you installed TWRP and rebooted, the May bootloader detects the changes TWRP installation made to your boot image and aborts the boot process resulting in your bootloop. Additional detail and information can be found in the linked thread and solution should be towards the end of the thread. You have a few options I think (assuming you can get into fastboot/recovery mode) - you can temporarily resolve by reverting back to the April 2017 bootloader which does not have the additional boot verification procedure or you can follow the steps to flash Chainfire's VerifiedBootSigner.zip if you prefer to get fully on the May update (including the May bootloader). Details are in the thread below. Good luck!

Just started with me today too.
I cannot get into recovery or boot loader
rebooting using the hard button just brings up this Dump to EXT4 and then into the ROM that is havnig a ish ton of force closes.
My plan is to back up some stuff I need to copy off the phone and then start factory reset from within settings.
EDIT:
I was rooted running stock
All i did was run a backup in TWRP
issues started after reooting.
Once i factory reset and re Root i will see if I can restore backup, maybe

I had forgotten that after I booted normally just before installing TWRP, the May OTA happened to arrive and I went ahead and installed it. Then the problem started after I installed TWRP. I used @mikaole's advice and got into bootloader (can't believe I hadn't done that, given all the button combinations I'd tried).
I re-flashed the April update and now the behavior is exactly the same except that the white Google boot screen lasts about 5 seconds and after a few boot tries I land on the "No command" screen. That sits for about a minute and boots again, landing again on "No command." Power+vol-up gets me to recovery mode but all I can do is go to bootloader or get back to "No command." I tried a factory reset, same result. I tried re-flashing April again, same result. Now I think I have the May bootloader with all else April.
I ran this:
Code:
fastboot set_active a
because I noticed that flashing the bootloader was always going to b. After flashing the bootloader again and seeing it go to a, the phone boots normally. I'm going to let the May update happen and wait to root again until after that.
One thing, I don't think the link you provided is the one you intended - there's none of the info you said would be there.
This has been very helpful. You and @mikaole got me through this. Thanks!

They flashing all the parts of the image manually. Something like this happened to a buddy of mine and using the flash all wouldn't fix. He couldn't get the device to boot until he did all the images manually.

Pixel bootloop
Hey guys, this is the only thread thqt i found here on XDA about pixel and pixel XL bootloop issue.
I'm about to buy a used Pixel 1st gen phone for really great deal, because it is in this bootloop. As the owner sad, it was on the Oreo upgrade. I'm wondering if its possible to fix it... What you guys say?
Thanks!!

Well that depends. If the owner unlock the bootloader and then relocked it it could have screwed it up depending on what he was doing with it at the time resulting in a bootloop that cannot be fixed because it's hard brick now. I say can't be fixed only because the only way to get it fixed as far as I know is to contact someone here on the forums I'm not exactly sure who it is but they do fix hard bricked pixels for money. If I were you I would try and figure out if that's the case before buying it.

Yes, that's my biggest fear right now... He sad he never had done anything like root or custom rom, he just had done a system update and the phone never boot correctly again.
I have a little bit of knowledge in android, i was thinking if just putting a custom rom it wouldn't solve, because i had other devices that i had put in bootloop and i was able to fix it just putting a custom rom...

Yeah if you can get into recovery you can side load things. And if you can get to the boot loader screen you're fine.

Pixel XL stuck in Boot Loop after PPP5 installed

My Pixel XL downloaded and installed PP5 yesterday, seemed to go okay. Initially, it would boot but spontaneously reboot after 1-2 minutes of run time. But it degraded and now it is stuck on a white screen with Google, and reboots before the animation begins.
I can get into the Bootloader, but when I try to select Recovery mode it just goes back to the white boot screen and repeats. In Bootloader I can select Off, but it only shuts off for a short time then reboots on its own into the boot loop.
This was running stock Android, bought from Google Play store, unlocked, 32GB version, and I had run the previous 3 versions of Android P Beta without problems.
Is there anyway I can do a factory data reset without the Recovery mode?
Thanks,
...Patrick

You didn't relock the bootloader did you? After unlocking it?

No, I did not lock the bootloader. The phone was originally unlocked, and I never rooted it. It was completely stock. But it was definitely acting crazy....at one point I did see the Recovery mode but I did not know at the time what to do with it. Once I had a minute to research that on my laptop then it would never go back into Recovery mode.
So maybe I inadvertently locked it, but not that I know that I did it.

I ended up asking uBreakiFix to diagnose the problem....and they indicate it is a bad motherboard.
It can be repaired for $380. I passed, and now own a brick that flashes from one Boot to the next, occassionally running for 30 seconds, but not quite long enough for me to run Reset Factory Settings.
Oh bother, < 2 years old.

Stuck in boot loop even after factory reset. Able to get into bootloader and recovery

Hoping for some help or alternatives to fix my fiancee's Pixel XL. Last night the phone just kept flashing the 'G' logo on for 10 seconds, off for 10 seconds. She said the phone was close to dying before it happened, and I imagine it probably ended up draining the battery afterwards with the constant bootloop. Plugged it in all night but the charging screen didn't come up and would just stay in the bootloop. I could get it into the boot loader (power button and volume down), but it wouldn't go into recovery mode and instead would go right back to the boot loop.
So I tried a battery pack to charge it and it still didn't show charging, but I was able to get it into recovery mode eventually, but still boot loop afterwards. At one point, after leaving it on boot loader menu while attempting to charge, it eventually just tried to start itself and made its way to the second Google splash screen after the main G logo. Looked like it froze there though and I couldn't get it to that point again.
On my way to work this morning I tried plugging it into my car's USB port after powering off from the boot loader, and this time I kept flashing that it was charging (looked like it was 3/4 charged but not sure how accurate that is). So I got into recovery again and tried 3 factory resets consecutively. Still bootloop after attempting a startup afterwards. There was a similar issue a couple weeks ago where it looked like it was stuck in a bootloop, but it turned out the phone actually was dead that time and the charger wasn't working. Once we switched chargers it booted right up.
Any other suggestions or possibilities? I don't have much troubleshooting experience otherwise. Phone is fully stock, Google Fi. Any other info I can provide please let me know!

well, i'm not sure if it makes a difference, but now for some reason i can't get into recovery mode again. just goes into the boot loop. It also goes into the boot loop as soon as I plug the phone in to charge.

I assume you can't get into the bootloader using power and volume down buttons?

I have always been about to get into the boot loader. Actually i can get into recovery again as well. Seems if i let it sit for a while it'll go to recovery again. Maybe heat related.

My OG Pixel did the same thing to me one morning. I tried everything to revive my pixel but nothing worked. I did some digging and it turns out there is an issue with the storage on the phone. It's just a old fancy paper weight.

If you can get into recovery, have you tried to sideload a full ota.zip (not an update)?

I haven't. I see that Google has all the ota's on their site. Is there a specific one that i might want to try? The same one? Go back a few? Will i even be able to sideload if my phone is fully stock?
Edit: sideload adb successfully but no change. I loaded the 6-5 ota which was what i already had.

Sounds as if it's time to just try stuff and see what sticks. Regarding using an ota, it works if you are stock, and I sideload it even if I have installed majisk or installed another kernel. It typically works for me with fewer chances of blowing things up than flashing a stock image. Regarding what to try next, you may have already gone into recovery to check the install function to see if your storage still appears and try to flash anything that worked in the past; if you have a backup in twrp you could try to restore it; you could wipe cache and dahlvik; or even sideload an earlier ota version that worked. Since the 6-5 ota did not work nothing really jumps out to me as obvious. One final caveat, I once had to reboot a sideloaded ota a second time before my pixel booted properly. If I think of something else I'll post again.

I took it to ubreakifix and they told me that this is indeed a known issue with pixel xl's that they all suffered from a faulty motherboard and that is indeed the cause here. Said he thought there was actually a class action about it so I'll have to look into it. Really pisses me off that Google repeatedly told me it's not a known issue when their authorized repair center says it is.
Anyway i have a warranty with Upsie that I'm hoping to get this replaced with. We'll see.

I'm assuming you tried booting into twrp recovery, going to reboot, and picked slot A ( or B if already in A) to reboot to and then rebooted system? A lot of the times simply switching slots from recovery and then rebooting is the fix. At least for me.

手机早期经历的情况得说明一下。root没有？Twrp是谁的？

Also, for anyone else having this issue, try rebooting into the bootloader. Connect to PC, and try fastboot --set-active=a
If this doesn't work, try booting back into your recovery image using fastboot boot *whatever you named your TWRP recovery image* and then flashing your twrp.zip again in recovery, and when rebooting if you're in slot B choose slot A in recovery to boot into.
Also keep in mind in Windows 10, it uses Powershell, so commands have to be typed in .\fastboot not just fastboot or it won't take it.
