No recovery & no adb boys! F@ck! Just boot loops all day. This also happened to my brother and sister in law too I guess. They were a month out of warranty & bone stock. I'm wondering if I should wrap this thing in a wet towel and fry it out just call for help as is. It's under warranty until the end of next month. I am rooted though.

Totally random too! Been on the same rom for like 4 months. My wife came home set it on the bed next to me and was treated to complimentary boot loops... :(

Hi everyone from Italy, just want to share my experience.

My phone went in BLOD, I sent it in warranty and they replaced my phone with a completely new one.
[Nexus 6P Q&A, Help & Troubleshooting] hy565:
just got the BLOD on my 1 year 3months old 6P, had been running pure nexus 7.1.1 for a few months before that. Was just on whatsapp and it rebooted suddenly, and now the bootloader is the only thing I can access. Tried formatting every partition and flashed stock, but still can only access bootloader. I just replaced my battery and housing too, what ****ty luck I have.

Is there anything else I can try at this point?
[Nexus 6P Q&A, Help & Troubleshooting] pinepineapple:
I will get back my RMA NEXUS 6P tomorrow from HUAWEI.

Should I keep 6.0.1 and not upgrade to 7.0.1 ?

Because of the limited warranty, I want to avoid any boot loop again.
[Nexus 6P Q&A, Help & Troubleshooting] v12xke:
Not if you cannot boot into recovery mode. That is usually the end of the line. There was one guy who bootlooped on PN and used Skipsoft's Toolkit (on XDA) and claimed got it back. He flashed stock and used the optional format option. Why not give that a shot.

---------- Post added at 08:41 AM ---------- Previous post was at 08:37 AM ----------

No. You should upgrade the phone to the latest build/security level. There have been many instances of MM devices bootlooping. It has never been proven N was a contributing factor. It is a hardware defect.
[Nexus 6P Q&A, Help & Troubleshooting] sebasanchez:
I was wondering the same. It's a shame that we don't known the reason
[Nexus 6P Q&A, Help & Troubleshooting] v12xke:
We do. Hardware failure, almost always the motherboard. Manufacturing defect by Huawei.
[Nexus 6P Q&A, Help & Troubleshooting] CyberpodS2:
I was staying on 6.0.1 Pure Nexus for a couple months since my RMA but this week I gave in and installed Dark Rom, Flash Kernel and Magisk. If it goes south I'll tell you guys but I figured hell I wanna enjoy my phone.
[Nexus 6P Q&A, Help & Troubleshooting] pinepineapple:
The motherboard changing is a major solution ,but may not a reason of BLOD.

There are many assumptions to explain BLOD, and GOOGLE has not officially announced

yet.
[Nexus 6P Q&A, Help & Troubleshooting] CyberpodS2:
I'm convinced Huawei is waiting out the warranty cycle. Google has consistently told users it's on the hardware side. Huawei was giving people breaks on the expired dates but recently they seem to be holding a harder line based on the posts I've read.

[Nexus 6P Q&A, Help & Troubleshooting] CyberpodS2:
If you dig through the dozen threads regarding looping you will find some posts that reflect what the people got from Google. I don't believe there has been anything official, only representative statements.
[Nexus 6P Q&A, Help & Troubleshooting] slicer2k:
my phone is boot looping out of the blue!

I was watching a video in youtube then the video locked up restarted the phone by itself and now all it's showing is the google logo, can't enter recovery mode.

2 days ago i have updated from the last Nougat Patch.
[Nexus 6P Q&A, Help & Troubleshooting] CyberpodS2:
In my experience, no recovery is BLOD. If your bit loader is unlocked, one thing you can do to validate your phone is dead is flash a full factory image. In my case it flashed without error but nothing changed. Still dead.
[Nexus 6P Q&A, Help & Troubleshooting] slicer2k:
Luckily i haven't unlocked my nexus 6p. It still in warranty till june 9 but it will be a major pain in the ass to RMA since it was bought in the U.S but i live in another country and i can't RMA directly to them.
[Nexus 6P Q&A, Help & Troubleshooting] ajkahij:
I have an Nexus 6P, the phone is in infinite bootloop. Doesn't respond to any command. The only thing I can access is fastboot via cmd for 3 seconds before it continues the bootloop. Does someone has any idea that could help?
[Nexus 6P Q&A, Help & Troubleshooting] v12xke:
You might have had a chance if the bootloader were UNLOCKED like he said, but sounds as if it is time for RMA.

---------- Post added at 03:25 PM ---------- Previous post was at 03:22 PM ----------

Bootloader locked? Are you able to access recovery mode? Stock recovery or TWRP?
[Nexus 6P Q&A, Help & Troubleshooting] ajkahij:
Unlocked. I can't access recovery, I can only access fastboot screen but it won't respond to any button command and comes back to bootloop after 2~3 seconds. TWRP
[Nexus 6P Q&A, Help & Troubleshooting] v12xke:
Usually no recovery mode means you are finished. How about if you just leave it in bootloader and don't touch the buttons.... stable? If unstable in bootloader I don't think anything can be done. Sorry.
[Nexus 6P Q&A, Help & Troubleshooting] ajkahij:
Thanks for your help, I appreciate it. If I just leave the phone it keeps rebooting. I've tried flashing the stock bootloader, had success on the operation but made no effect, keeps rebooting. Does it looks like a hardware issue?
[Nexus 6P Q&A, Help & Troubleshooting] v12xke:
Yes. Usually no recovery mode ends up being hardware. Have you tried to fastboot format cache and userdata partitions? Note any errors.
[Nexus 6P Q&A, Help & Troubleshooting] ajkahij:
Yes, I tried. No error, it performs the erase normally.

And I can lock and unlock the bootloader easily too, basically I can execute any command on fastboot
[Nexus 6P Q&A, Help & Troubleshooting] CyberpodS2:
That is pretty much it then... back for RMA.
[Nexus 6P Q&A, Help & Troubleshooting] v12xke:
Ok, these are probably both for other people reading this but NEVER lock your bootloader when trying to recover. If you are unlocked to start with, never re-lock the bootloader. Secondly, the command in bold was format. Not erase. If you can execute any fastboot command, format the partitions and try flashing a full Google image using flash-all.bat. If this completes with no errors but still bootloops, then you can put it down and work on getting your next phone.
[Nexus 6P Q&A, Help & Troubleshooting] ajkahij:
I've used the format command, not erase.

The first photo is the cmd return when I tried flashing a full Google image with flash-all.bat.

The second is the cmd return when I tried flashing a full Google image using this order of commands:

fastboot flash bootloader <bootloader file name here>.img

fastboot flash radio <radio file name here>.img

fastboot reboot-bootloader

fastboot flash recovery recovery.img

fastboot flash boot boot.img

fastboot flash system system.img

fastboot flash vendor vendor.img

fastboot flash cache cache.img

fastboot flash userdata userdata.img
[Nexus 6P Q&A, Help & Troubleshooting] v12xke:
Sorry but all I see is erasing as part of the scripts. Do not flash cache or userdata .img's. Manually format all the partitions one after the other, especially userdata, system and cache and note any errors. I see: error on userdata: can't complete "erase"... can't determine partition type. This is a problem that may be solved with fastboot format.
[Nexus 6P Q&A, Help & Troubleshooting] ajkahij:
I was able to format all the partitions except the userdata
[Nexus 6P Q&A, Help & Troubleshooting] v12xke:
A simple Google of the error "failed data transfer too many links" yielded (literally the first hit) three people had a bad usb cable or port. They changed the usb port and/or used a different cable and the format completed successfully. You need to get that partition properly formatted (and the others) before using the flash-all.bat again.

flashing recovery image to boot partion will get you back into recovery after a few boot loops. and the guy who asked about the emmc with the twrp command. it just goes back into bootloop when i enter that
[Nexus 6P Q&A, Help & Troubleshooting] mosd:
I had this. Left it to the store where i bought it. They changed the motherboard and it fixed the problem..
[Nexus 6P Q&A, Help & Troubleshooting] anikadam:
Having the same problem, was on Purenexus 17032017 build with stock rom kernel, kept bootlooping. Reflashing the rom helped the first 3 - 4 times, but then the bootloop became persistent, tried going back to stock 7.1.1 through fastboot, when that didnt help even wiped out userdata, still no luck.

My bootloader is stable, fastboot working and can access TWRP. With TWRP 3.1.0-0 it keeps asking for decrypting password, but rest of the twrp is working fine.

Anything that i could try ?? Trying MM now, anyone tried going back to 6.0.1 ?
[Nexus 6P Q&A, Help & Troubleshooting] 5.1:
Hello... Problem is not ROM or Android version dependant. If you read the last few pages you can see devices locked/unlocked, stock/custom ROM, Android 6.x/7.x.x.

If I was you, I'd backup important files, flash stock firmware. Contact Google or Huawei explaining your issue and ask for RMA.

Lock the bootloader before sending your device.

Good luck...
[Nexus 6P Q&A, Help & Troubleshooting] anikadam:
i know its been happening with everyone. Since i did mention that i wiped out userdata, dont really have anything to back up. i have contacted google and huawei. There are people with bootlooping even in bootloader mode and no recovery which is both stable and available respectively in my case. i havent seen anyone with a stable bootloader and working twrp.
[Nexus 6P Q&A, Help & Troubleshooting] v12xke:
Users affected by BLOD cannot access to recovery mode, so your issue is different. Reverting to an earlier version of Android is a waste of time. You could have corrupted a partition. Fastboot format cache, userdata and system. Not wipe with TWRP. Fastboot format. Capture any errors. Then install 7.1.1 full image (not OTA) using flash-all.bat. If you flash manually do NOT flash userdata.img or cache.img. What is your battery capacity as measured by Accubattery? If your battery is dead/dying/severely degraded you are putting off the inevitable of replacing the battery before proceeding.
[Nexus 6P Q&A, Help & Troubleshooting] 5.1:
Yeah you mentioned you wiped your data troubleshooting your bootloop issue... Anyway that's​ just the usual advise anyone can give to someone before sending his device for repair.

There were users which had random reboots + recovery access​ not long before their device failed them. If you wiped everything, reinstalled a stock firmware which didn't fix the problem, I don't know what else you could do.

If you think it is reliable enough for you, keep it. I wouldn't waiste my time on it if it's still covered by warranty. This is my humble opinion.

Good luck... :good:
[Nexus 6P Q&A, Help & Troubleshooting] anikadam:
I did fastboot format. If i flash-all.bat then should i format the userdata and cache after that ?

My battery was working OK.. not great but ok..

------------------------

Tried the flash-all.bat and formatted the userdata and cache as advised.. still bootlooping. i did wipe the cache partition before adb sideloads and everything.

Nothing is working !

How do you lock your bootloader if its bootlooping!??????

---------- Post added at 02:57 PM ---------- Previous post was at 02:54 PM ----------

Now I'm in bootloop after just using gps and Bluetooth stream to my car! Wtf smh
[Nexus 6P Q&A, Help & Troubleshooting] v12xke:
Ok.... No, you format the partitions first, before running the flash-all.bat. It is not required afterwards. Some people were creating new problems by manually flashing userdata.

If you formatted the 3 partitions first, received no errors, and then used the flash-all.bat with a full stock image I don't know what to tell you. What is the SHA-256 Checksum of the image you flashed with fastboot? This checksum is given on the Google Factory images page. Did you receive any errors at all when running flash-all.bat? After flashing the full image, try a factory reset from stock recovery.
[Nexus 6P Q&A, Help & Troubleshooting] 5.1:
Well, as long as he has bootloader access, i guess he can execute whatever fastboot command he wants

And sorry for your bootloop... :(

Thanks for pointing the format partitions thing before flashing. Forgot about it. :good:

Cheers...
[Nexus 6P Q&A, Help & Troubleshooting] ajkahij:
I press volume down and power button then it goes to fastboot and I have about 2 seconds before it reboots.

I've seen this and tried different ports (unfortunally I don't have other cable to test) but I think it might be returning this error because the phone reboots before the operation is finished, does my theory it makes sense?
[Nexus 6P Q&A, Help & Troubleshooting] v12xke:
I think you meant UNLOCK your bootloader? No one in their right mind would lock the bootloader while stuck in a bootloop. That's a good way to brick your phone. If you never enabled OEM Unlocking in Developer Settings, it's not possible to unlock unless you can boot System and do that. If you have recovery mode, -and- previously enabled USB debugging (Developer Settings) you may be able to salvage data, backups, etc. If locked, the only thing you can do is sideload a newer OTA from recovery mode. A little more information on your current configuration would be helpful.

---------- Post added at 02:54 PM ---------- Previous post was at 02:36 PM ----------

Could very well be, but until you get a new cable you won't know. Is your bootloader mode stable with no cable connected? If it bootloops after two seconds without a cable connected you're pretty much dead in the water.

7.0.0 factory image - NBD91K - sha-256 checksum - 6f206c95da22ae17a26e5da22a14a09e676ded955ec401948493433c4b927fac

Formatted the 3 partitions - cache, userdata, system

Got this....

Then used flash-all.bat - got

1. archive does not contain boot.sig

2. archive does not contain recovery.sig

3. archive does not contain system.sig

4. archive does not contain vendor.sig

Rest everything is OKAY.

Though this flash-all.bat does flash the userdata in the end.

Gonna try with N4F26T Mar 2017 7.1.1 factory image.... sha-256 checksum - 50ddc7027f726f32a93d1035b95cdc56518b07edb3c0507e27edb41fcb0dc5a6
[Nexus 6P Q&A, Help & Troubleshooting] v12xke:
You can safely ignore the *.sig warnings. You've done everything correctly. I didn't see the cache format but I can see you know what you are doing and don't doubt it. I was going to suggest the same 7.1.1 image. If it is still looping, try a factory reset from stock recovery afterwards. After you've tried the above, double check the bootloader version (bootloader screen)-should be 03.64, and the recovery build version (recovery screen)- should be N4F26T. This will confirm these partitions were written to correctly. If these fail, I just don't know what to tell you.
[Nexus 6P Q&A, Help & Troubleshooting] CyberpodS2:
Coming from a user (me) who had exhausted ever chance of recovering from BLOD without any fix besides RMA, here's the deal regarding errors while fastboot flashing. I flashed multiple partitions, multiple recovery and vendor images and multiple stock images with ZERO errors. Both manually and with the .bat scripts. I'm my opinion, if you have functioning fastboot and no other options from the boot loader besides the barcodes without boot looping, your done.

[Nexus 6P Q&A, Help & Troubleshooting] 5.1:
Hello... Imei number is affected to only one motherboard.

It appears some replacement motherboard come without imei and some with a manufacturer one. Either it's already done by Huawei or maybe the shop cloned an imei from a dead phone?!

Does it report as a valid Huawei N6P imei?

[Nexus 6P Q&A, Help & Troubleshooting] v12xke:
If your bootloader is locked, and the factory reset did not work, you are limited to side loading a newer build OTA. Unfortunately you cannot flash a full image when locked. In the event a partition got corrupted, you should try fastboot formatting (not erase) userdata, cache and system. Capture the errors, if any. Then if you were not already running the latest March build (N4F26T or Verizon NUF26N) try side loading one of those. If you already were running the latest, then you can either try a 7.1.2 OTA or wait until next week when the April security update comes, presumably Monday, April 3rd.

Only you can decide what you really want. Some users have their phone since the launch and have never had any issue with battery, nor bootloop.
