FIX AVAILABLE!!
I bought my TF about 15 days ago, rooted it and installed CWM recovery, and it was running just great. Then, the ICS update came along and i just waited for the CWM package to update mine. No problems in the update process, but the random reboots started happening, so i thought the problem was that i updated without wiping, so i did this. No dice, still getting (not so) random reboots. So, i thought maybe it was the CWM package. I downgraded to HC via NVFlash, then let it update via FOTA. Even then, the random reboots persisted. Then, i noticed the tablet never rebooted while in use, but only while in deep sleep state. The "No Sleep" widget is the current workaround, but then, you risk getting a SOD.
So, from what i could gather until now, the following things are NOT the cause for the RRs:
1. Updating without wiping.
2. Updating via CWM.
3. Rooting.
Well, i got really sick of this problem, so it's time to do something about it. I am trying to gather as much info as possible to try and narrow down the possible cause for the random reboots, so i need everyone that is facing the same issue to give me the following info:
1. Serial number of your Transformer
2. Firmware region (TW, US or WW)
3. Logcat before the reboot
For number 3, you need to open Terminal Emulator, and do this:
# su -
# logcat > /sdcard/logcat.txt
Then you just turn off the screen and let your tablet go to deep sleep. After it reboots, post here the info above and attach logcat.txt.
Please, only use this thread to post the info i asked. Thanks!
Update: Some users contacted ASUS and it seems they are aware of the problem. A fix is supposed to released soon, in the form of another OTA update.
Update2: Very good knews for rooted users. The test13 version of guevor's kernel is able to let the TF deep sleep and not reboot. Link to his thread:

THANK YOU, GUEVOR!
Good idea. Mine just randomly shuts down during sleep, as opposed to rebooting. Shall I contribute too?
Have you tried a factory reset?

Can´t give you a logcat yet but here's my TF101 info:
FOTA to ICS 2 days ago and started random reboot's... Not Rooted (never has), no service/app/etc.. killer, but i did disable all of ASUS crapware on the Apps manager.
I was able to caught one of the reboots (it's freeze on the ASUS logo) and when i hard reboot it, during boot sequence appear some message saying that was finalizing update (this was after the FOTA and after other 2 random reboots. I did reboot the device after the update at least twice before experiencing the 1st Random Reboot).
info:
S/N: B90KAS146231

as soon i have the Log i will post.
Hope this help somehow

Every kind of update method that you can think of was tried. In that case, yes, it was wiped. Several times, in fact.
Please, post just what i asked. I want this info to investigate the issue. Post on another thread if you want to share theories or something else.

Mine was never rooted, 100% stock, took the ICS OTA on Friday moring, ran great all day, I woke up Saturday morning (I had docked it and put the doc on the charger friday night when I went to bed) and it was stuck in a boot loop. Now I'm looking at how to NVFLASH it back to honey comb to recover it, might as well root it now.

still waiting to freeze or reboot ... for now 493K of logcat

This is going to be a problem in the kernel like it has been on previous releases. When kernel source is released then the kernel devs will fix it and then asus will fix it. My SODs are caused by a kernel panic so until we get an updated kernel we need to get asus to release source.
I am mostly a longtime lurker/user of XDA but I thought I should contribute to this thread.
Bone Stock 16g TF101-A1, Refurb purchased last week from online vendor. Still getting used to the tablet format but I also purchased a TF101 Dock.
I noticed yesterday that I had a couple of random re-boots. Didn't know if it was related to an update or why this particular tablet was "refurbished." About 7 hours ago, this morning, I got multiple re-boots. Splash screen then power off and on again. I saw at least 15 re-boots before I started looking around for solutions. I tried the stock rom (downloaded from Asus) and re-boot to recovery w/o any success. Re-booted and wiped (hard reset) multiple times as well.
Still no complete boot but I had two separate and distinct paths that displayed:
1. it would boot with an android bot asking for a password and the keyboard displayed
2. It would cold boot into the "Start" screen like a normal set up.
I did manage to get the recovery started only to reach the bot with the exclamation point and no further progress at recovery.
In either case, typing a password of any kind did nothing, and hitting start and beginning the set up process did nothing but continue the re-boots/splash screen/power up/power down.
Finally connected to my laptop and it succeed in a complete boot and I was able to set up and connect to my wireless. It did not re-boot for several moments and I was able to observe the "About" page from the settings. I was still running
HTK75.US_epad-8.6.5.21-20111216
I also noticed that it was actively downloading a "firmware update" I went through several more re-boots until it finished the download and then I installed the firmware w/o any further trouble. In watching the download, I noticed re-boots at 31%, 32%, 41% "download completion", and one or two more before it fully downloaded. Of course, it did re-boot upon completion of the upgrade.
I am now running Android version: 4.0.3 Build number: IML74K.US_epad-9.2.1.11-20110221
Everything has been stable for an hour or so of moderate use including installation of multiple apps.
FWIW, I think that the reason my problem started is that I had my WiFi set to turn off when screen is off. I believe my incomplete download started the re-boots and my settings "may" have contributed to the incomplete downloads that started the rest of my issues.
Thanks to all of the "regulars" around here that are busy helping us customize our devices. This may not be my first post, but I think I have less than 5 posts right now. Hope this helps in discovering the causes of the re-boots.
ICS OTA on Saturday, 2 reboots already, stock rom, 100% original, Italy. Should i contact Asus?

Just Once
I have experienced a single random reboot since applying the OTA ICS upgrade to my US B70 TF101.
That was then...
Now the tablet is virtually unuseable. Not only are there random reboots, but lags and freezes ad nauseum. I am NOT a happy camper
I don't believe this has been mentioned before.
I just saw my device go into random reboot in sleep. However, this time the device completed the boot up sequence instead of getting stuck on the Asus loading screen...
All I did different was changing WIFI sleep policy from "never" to "on during sleep", which I don't think is the cause of the change.. I guess it all depends on luck weather the device gets stuck or complete the boot up sequence.
So perhaps the problem is caused by a combination of a bug in the deep sleep state and the CPU governor?... This is purely my speculation.

My device never gets stuck in the ASUS logo, it always completes the boot process, and the wifi policy is the default one, so i don't think it's related to it. But it's probably something to do with the kernel and deep sleep state. Even with the wifi policy set to never turn off, the device enters DS.

reboot cant have anything to do with the apps (like google earth) as those will simply FC on fault and are not capable of taking system down. this must be a kernel or driver issue.
transformer prime got ota update recently that was supposed to fix reboots and it contained new wifi driver. so possibly this is something to do with wifi.
my wifi sleep policy setting is to be always on when on power and sleep when screen is off on battery.
never had a reboot when plugged in, had a few always on battery power - so it might be related to wifi beign powered on in sleep to do periodical email check. just a guess.
I am running stock unrooted atm. I reverted back from rooted to stock before the ota update.
I generally get one random reboot each day. They happen when my transformer is in sleep mode always. It'll be st next to me asleep and then I notice the screen turn on and it is rebooting. My "Keep Wi-Fi on during sleep" is set to "Always".
I removed root as I wanted to see what stock performance was like. Apart from these reboots I'm totally happy.
2.6.39.4 and WW_9.2.1.11
Not sure how much help that'll be to others, but there you go.
I had these random reboots aswell on my device but since yesterday morning it stopped.
- Removed SetCPU
- Forced 2D rendering to the GPU.
Still testing it but so far no reboots
Stock ICS + Root
Getting the same exact thing, froze during boot up one time.
Running S/N BBO
Tossed a ticket into Asus letting them know, hopefully I get a response back soon.
I had random reboots the first day after updating,
but have set
1. the wifi to be off when the screen is turned off (in wifi settings), and
2. have turned off the location service that uses your wifi to aid positioning (in location settings).
and this seems to have stopped the reboots.
Hope this helps someone.

My A500 hasn't been acting quite right. Since I upgraded a while back to a FLEXREAPER rom from Taboonay (HC) I've had numerous SOD issues, but even more so worse and worse crashing and hanging.
Things I've done:
Full wipe/install of latest FLEXREAPER, Lightspeed, Taboonay (3.1). My A500 would hang even during initial setup (google account, etc). Eventually I'd get through the setup and it would still crash (screen freezes) or SOD. Oddly enough, I can't seem to format my internal sdcard .. but I have wiped everything else several times, and absolutely before installing any of the ROMs.
It would also, many times, not even boot. The white power light would come on, the vibrator would spin, but nothing would happen on the screen. It would boot about one in five times.
I then tried going back to a reinstall of old HC Taboonay 2.2 .. it worked for quite some time before, but now it's hanging and crashing just as it did with the ICS ROMs.
Up to this point I didn't touch the bootloader, which meant I was on the old HC bootloader. But in doing a lot of reading it seemed that many SOD issues were fixed with the new ICS bootloader (unlocked and patched).. so I used nvflash to flash a the ICS bootloader.
Well, this solved my only-would-boot-one-in-five problem and it boots everytime. But it still crashes. I even had it crash in CWM 1.7 just like everywhere else ... frozen screen. I've never seen that before in any of my Android devices.
I really don't know what's happened at this point. I'd be happy just to go back to a version of HC that works. I'm downloading timmyDean's V4 3.2 package (the depositfiles link is the only one that works .. and it'll be done in ELEVEN hours.) to attempt a shot at going back to full stock. But considering that's 11 hours or more away, without knowing it'll work .. I thought I'd ask.
Is there any way to downgrade from the ICS unlocked/patched bootloader?
Is there another bare-metal restore for HC out there besides the hellishly slow timmyDean V4 on depositfiles? Another location to download it from?
Is there anything else I can do?
Thanks ...
Found EUUs_SBK_Acer_A501_0.017.01_PA_ATT on some russian site.
I was able to reinstall everything back to 3.01 from the EUU loader. However my A500 still has serious problems.
- During loading the EUU, getting it in AXP mode worked every time, but bouncing it to Download mode worked rarely.
- Most of the time when attempting to power on it will turn on the power light and vibrate, but nothing shows on the screen.
- Sometimes if it makes it past the above, it will display "ACER" but go no further.
- Once actually loaded into an OS (doesn't seem to matter which one) it will lock up after a short while with the screen frozen. Only a hard power off (hold power for 5 sec) will shut it off.
- It will simply die if soft powered off .. not right away, but after some time.
So, is my A500's hardware broken? I can't seem to get any part of it stable.
Many reinstalls later, all options expired. Returned to Acer for warranty repair.
I bought a refurbished TF101 about 6 months ago. I rooted the device and tried various ROMs until I settled upon "Revolver 4 by Gnufabio | 4.1.1 Stable". Life was good, no random reboots, no sleep of death just great. I then installed a game called "Dead Trigger" that came up recently on the Play store. The game did not load, crashed without a FC message and so I uninstalled it promptly. Then I started getting video corruption on my Live Wallpaper (Blue Skies). Random reboots soon followed. Time to start over.
I used CWM and wiped the tablet from there (data, cache and Dalvik) and reinstalled Revolver. It did not work. I used the EasyFlasher tool to return my tablet to Stock using the Asus provided firmware from their website (.24). It seemed to work well, as I started over with my "new" tablet and synced to my account, etc, etc, etc. But now I can't use it without it rebooting every 30secs to 1min. It will go into a Sleep of Death on a random basis also. I have not installed any programs on it, I tried not allowing a restore of my Google settings and cannot for the life of me figure out what is going on.
I am unaware of the SBK version, as their is no indication on the tablet of its serial. What vital step am I missing here to revive this tablet? Any help would be appreciated.
Thanks

The RR and SoD come standard with asus stock FW for most people, there is a new .27 update you could try that apparently fixes things, but it made things worse for me
The serial number is generally on a sticker next to the charger port of the tablet half, B4O > B60 and some B7O are SBK1, after that are SBK2
If you are SBK1 you can use NVFLASH to clean install the OS
I decided on Stock FW Rooted and CWM with PERI, then Guevors Kernel
So far so good, stable for a couple days now
Thanks for the quick reply. I did try the .27 update OTA update after getting back to Stock. No help.
The sticker in question is missing. Unknown SBK. I used EasyFlasher using SBK Ver1 and it worked to install the Stock .24 OS fine.
I will give the Stock FW Rooted a shot and see if that works

If the flash worked with sbkv1, then more than likely the unit is sbkv1. Otherwise, it shouldn't have worked at all . As the other poster said, RR and SoD is pretty common with the stock Asus firmware for some people -- you might try returning to Revolver now that you've gone back to stock, and start on Revolver again with a clean slate.
I am also running the same setup as the previous poster, stock .27, rooted with guevor's kernel. Been that way for only a day right now, so I can't say much about it yet.
Okay, so here is what I have done. I first used NvFlash to flash Stock .24 successfully. I then extracted the ASUS .24 firmware file (zip only) to the MicroSD card which the system took as an update and installed over my good work. It works, albeit with reboots still. I at least got it working and will try some more ROMs (Stock .27 first) with the suggested kernel. I just wish I could get back to the stable Revolver I had earlier.
Thanks for the help and suggestions.

If you used NVFLASH to get back to stock, you could have just let the FOTA update you to .27
Then you can root and so on after that
NVFLASH returns the tablet to factory settings, ie. as it was when you unwrapped it on day 1
Not good. My tablet seems to be in an internal storage hell. Every Rom I try to install will crash with moderate use after booting. I have tried NvFlash, EasyFlash, Wolfs Ultimate flash and downgrade, every variation of stock HoneyComb and ICS I can find. I cannot keep this thing stable beyond 5 minutes of use. I have tried multiple factory resets and wipes, run "Superwipe Full" multiple times and nothing seems to work. What can I do to recover this tablet before I just give up and send to ASUS (god help me) for assistance? Any help would be appreciated
Thanks StevieJ
Ouch. Sorry to hear about your troubles. Horror stories like this have prevented me from diving into the root and custom rom scene with my one and only tab. [I am leaning towards a Nexus 7 when it comes out, and will perhaps root etc when I get that. I feel like it's a safer endeavour with a non-locked bootloader]
I'm interested in finding out what may be causing all this, so I'll be subscribing to this thread. Sorry I can't provide anything more than good luck to you.

Ouch is right! I have rooted every Android device I have ever owned and this the first I have ever had this much trouble with. I just wish I could say I did "X" to cause it to happen. Oh well, maybe somebody knows something I have overlooked.
Note: I have Rogue XM Recovery 1.5.0 (CWM-based Recovery v5.0.2.8) running fine on the rom and it reboots into recovery okay.

Have you tried running it without the WIFI on? I went to my folks place with mine and it rebooted all the time as soon as it started up. It turned out to be a WIFI issue with the Dynalink router my parents were running.

Funny you should ask that. I just NvFlashed 9.2.1.24 and was using the tab with no WiFi, no account information and everything worked just fine. I then enabled WiFi to see what would happen and it still worked, but I had not logged in with any account information yet. It still worked fine, as I was able to surf the web with no problems. I then tried to add my account information and started getting crashes using the Play Store, syncing my accounts, etc. It seems to be linked to updating account information and not just WiFi. I will investigate further
Thanks
StevieJake
Adding an account, even a new account, will bring down the tablet. It reboots until it is only a dark screen that requires APX mode (VolUp +Pwr) to rebuild the tablet. I can get into recovery and also factory reset mode (VolDwn + Pwr), but that is it. I'm so confused
I found a CWM backup I had from back in March. It restored fine, but still had problems that resulted in multiple crashes and eventual death again. Oh Bother!!
StevieJake
Fixed it!
Here is what I did. I was always to get the tablet into APX mode (Vol Up + Pwr) so I NvFlashed 9.2.1.24 from this site:
http://xdafileserver.nl/index.php?dir=Asus/Asus+Transformer+(TF101)/. I did this 5 times, never letting the tablet fully reboot after I got the "success" message upon completion. I then did a data wipe (Vol Dwn +Pwr, then select Wipe Data and then Vol Up, Vol Up) 5 times. I then used the same NvFlash 5 more times and let the tablet fully reboot and entered my Google credentials. I had prepared a MicroSD card with the zip file extracted from the ASUS site that contained the latest firmware (.27) and placed in the root directory of the MicroSD card. The tablet recognized it as a system upgrade and installed the firmware grade with no problems. The tablet rebooted fine and showed the installed firmware. I then did a data wipe as described above 5 more times and then let the tablet reboot fully and once again entered my Google credentials. The tablet now runs all programs without faults, has no video artifacts on the live wallpaper I use (Blue Skies) and is running just great. I am able to update all apps with out errors from the Play Store which was also an issue.
I hope this helps someone to get their tablet back, as I used all the resources on this forum to bring this wacky method to restore my tablet. Thanks to all you unnamed posters for your help

I wouldn't expect flashing the same thing numerous times to have any more effect than the first flash, but if that's what it took for your tab to be re-born, so be it!
Congrats on the fix.

Not so fast!
Although the tablet did last longer (almost 2 days), it ultimately failed again to an unbootable state. Its back to the drawing board again.........

It may just be giving up, electronics are stupid sometimes and fail for no reason. I had a brand new HDD that worked for two days, I left the computer off for three weeks and when I turned it back on the HDD wouldn't even spin up :-/ Good luck buddy.
Okay, I'm done. Just got my RMA and am sending this puppy in. Thanks for all the help, I will try to post the results later when I get it back. Glad I made the impulse purchase for the Nexus 7, as I will not be totally without a tablet.
Thanks for all the help again

RMA and back from the Dead!
Well I got it back from ASUS after the RMA. It had a short visit in Texas, was returned promptly and appears to function normally. I never received any feedback from ASUS on receiving the tablet, what was wrong with it, what they did to it or when they shipped it. But its fixed. Running .27 latest firmware and seems to handle everything I can throw at it.
They did a bang up job so far and I am more than happy with their service.

Service Provider - Sprint
Model no. SPH-L720
Just picked up my Galaxy S4 from Bestbuy with stock 'Build no.' (MDC). As soon as i started using my phone, sprint pushed a 'over the air' (OTA) update. Had it downloaded, installed, and rebooted.
As I started using the phone more by clicking on the stock app. the phone starts to reboot itself. Long story short. I thought i'll fix it by rooting the phone. Same issue and reboot itself more, kept crashing.
I now unrooted the phone using Odin-OC for FULL ERASE since i have nothing on the phone to begin with. I'm guessing this is a hardware issue. I'm wondering if anyone out there that is having the same issue.
Thanks.
If the Galaxy s4 is faulty (hardware issue), the phone vibrate twice before samsung logo appear.
so from what you are saying as soon as you booted you got the MDL update correct? what "stock app" are you clicking on that is causing the phone to reboot? random reboots are commonly linked to specific software malfunctions most of which can be corrected easily. not saying you didnt get the bad one from the batch but if you provide more info we should be able to work out the kinks if its software related.

Sorry for the late respond, my phone will automatically reboot itself. While in any apps, game app and while using the camera to take pictures; my phone reboot itself. Once it is on, the phone will not respond (freezes) and reboot itself again and again. This usually stop by the forth or fifth time of continues self booting.

i know you said that you are no longer rooted but have you tried rerooting and flashing a differant rom?
Typically random reboots are kernel related. When rooted did you try flashing any custom kernels, mods, try OC/UV, or anything along those lines?
Otherwise, sounds like a faulty device, maybe bad memory.
Same problem
A week after getting the galaxy s4 my phone started rebooting typically 2 times a day sometimes none at all, contacted sprint they said to come in and there fix was a factory reset lol, so decided to root and install triforce rom with kt kernel , still getting random reboots, im playing with the kt kernal settings hoping to find a sweet spot
Honestly... I think it's the MF9 update. It hasn't happened to me, but I've seen it for plenty of people. Everyone here running build no. MF9??
I am now, but my reboots started right when the phone came out

Hi,
My N910F has recently been acting weirdly. It either randomly reboots itself, or just freezes for several seconds when switching screens or scrolling/tapping buttons. This started a couple of weeks ago on stock 5.0.1 (this version, I think) running Emotion kernel. This was running fine for a while; I didn't flash any new mods during this time, although I did switch between AEL kernel and Emotion once or twice without much success.
Thinking it was just one of those situations that called for a clean slate; I backed up my important stuff, booted into TWRP to wipe all partitions, then flashed stock 5.1.1 via Odin (this version, which I'm currently running). But even before I rooted it once again the phone was displaying the same aforementioned symptoms, both during and after going through the built-in setup wizard. This behaviour continued after flashing TWRP and AEL kernel v8.2, which I'm currently on at the moment. If it makes any difference I've also noticed that the lower my battery level, the more often it reboots itself. The battery level also "yo-yos" sometimes, usually at lower levels.
I've uploaded the relevant logs as advised elsewhere for anyone who can decipher them, as I otherwise don't know what to look for. This includes my last three kmsg dumpstate logs (just in case it's a slightly different cause each time), as well as my logcat and dmesg files (whatever they are lol) which I got using the SysLog app.
Any help would be appreciated, and if you need any more info please let me know.
Thanks .
*bump*
I have the same problem. Help would be highly appreciated. : )
*bump*
[UPDATE]: Once or twice when it's crashed as above, it would try and boot again but then reboot into download mode with the following text at the top of the screen above all the other info:
Code:
Could not do normal boot.
ddi: mmc_read failed
If I then pull the battery and turn it on again, it boots up as normal (at least until the next crash). Is this something that can be fixed with a fresh flash in Odin (or some other method), or is my phone on the way to its death?
Got the same issue + loses Wifi password after random reboot. Sent the phone back to the operator I bought it from 1 week ago and they did a repair. They replaced the USB-flex, did a firmware upgrade(?? ..was already updated to latest) and sent it back. I got it this morning and at first the phone now works fine and no more "mmc_read fail". But after some time the random reboots started again. Not so often now but still 4 times over the day and twice the wifi-password is lost and I had to retype it. Now I'm on the fence and just waiting for the first mmc_read fail" to happen before I complain and send it back for a second repair. I can not imagine this beeing beeing other than a hardware fail coming from a weak spot on the phone. I got the impression many people has the same issue and it really comes to life after upgrading to 5.1.1.
I also think the problem at the service shop ist that they just do a quick system test on a clean wiped phone and can't find the issue and think the phone is fine. After reinstalling my 200 apps and setting up my phone all over again, the workload causes the issue to reappear and I now have to ask the service shop for a deeper check. They accepted this as a warranty fix all though my phone has a knox trip (0-1)x4...
I've also faced random reboots on Lollipop. How i solved that? Simple. I downgraded to Kitkat. Lollipop still having lots of battery drains and bugs even on 5.1.1
[UPDATE]
I've decided to go through my network provider to get a replacement sent out to me, which they were happy to do after going through their line of questioning over the phone ("have you tried turning it off and on again", "did you try taking out your memory card and see if that helped", "did you try doing a factory reset", etc). They say it will get here tomorrow so fingers crossed for the replacement.
The ddi mmc_read fail has not reappeared yet..
It's strange.. Lately the random reboots are not wiping my wifi passwords anymore, but now after every random reboot the multiwindow is enabled and I've got to untick it in quick settings..
Latest: It seems that the random reboot may come from heavy account sync workload. I did have 5 Google accounts syncing on my phone + 6 excange accounts and when i disabled syncing alltogether the phone ran a lot smoother and the reboots stoped. So i deleted all Google accounts except my main account and for now thing seems to be fairly stable. I've also uninstalled all for me unimportant 3'rd party apps, reducing 3'rd party app count from aprx 200 to 150..
If things develop further I'll come back with more

Thanks fot starting this thread Jointfcfan...i am using 910P and have same issue of your post 1 and 4!!!!
Loosing hope on Samsung, it is really frustrating...
Tried cleaning cash, dalvic, reboots, on latest 5.1.1 k version...frozen all not neede games and apps ...only 1 google and 1 exchange account no auto sync
At next stage while rebooting it sometime going an error stating kernel panic and i have to pull battery to restart
Replacing USB-flex board at service shop has cured the "ddi. mmc_read fail" boot issue for good.
So to me it seems that when many people experiences this, the USB-flex board may have a built in design flaw making it a weak spot on the Note 4.
Also I found that the phone works A LOT smoother if using Nova launcher instead of TW. Random reboot count is way down and phone works almost normally. Still some lag, mostly when unlocking screen, but reboots happens only 2-3 times a day now. Still random rebooting enables "multi window" option every time..
I've also rooted the phone now using CF-autoroot. I've flashed Philz CWM recovery and using it to install Wanam Xposed. So now I can run Greenify properly in Xposed mode and automaticly hibernate apps including system apps..
NB! Be aware, flashing root and custom recovery trips Knox counter 0x1 permanently and MAY void warranty
I have also mailed my operator asking them to take in the phone a second time for check/repair, alt. replacing the phone. I guess when they did system check 1st. time without issues after replacing the USB-flex, it was done when phone was reset to factory and under no significant workload.

After upgrading to Andriod N on the 6p, many of us have been plagued by the Bootloop of Death and/or random reboots. Some have tried RMAs, have purchased new devices or moved to backup devices. Huawei has claimed software is the culprit and Google has stated that it's the hardware. Personally I've tried a clean install of the ROM, Dirty flashing the ROM, clearing the caches, etc.
Nothing has worked... Until now!
I'm days in without a single random reboot or Bootloop.
This advice is provided without warranty or any guarantee that it'll work for you but it may work.
I'm not a developer and I've not tried multiple devices.
Steps:
*Note I'm on the latest Pure Nexus build.
1. If you're currently stuck in a Bootloop, then leave your 6p to Bootloop until it actually starts or until the battery dies. If it starts skip to step 3.
2. If it Bootloops, then intervene occasionally by getting the device to boot into the bootloader (Hold down power and volume down). Once there, attempt to reboot recovery. It'll probably keep Bootlooping but occasionally the device will start up.
3. Once your 6p starts, download the ElementalX apk from the Google Play Store. Don't do anything else. I've only tried this app so it's the only one that I recommend for this "fix".
4. Download the ElementalX kernel through the ElementalX app and follow the prompts in order to install the kernel. Allow it to reboot. *You may be able to complete the following steps with the stock kernel.
5. Once your device has rebooted, open the ElementalX app and click the leaf icon in order to enable power saving. This will lower your CPU's freq, GPU's freq, and most importantly, it will disable the BIG CPU cluster.
After these steps were completed I haven't experienced any random rebooting or Bootloops. Yes, this ”fix" hobbles your device but it is still quite functional. I think that on Nougat the constant switching between the two processor clusters causes random restarts and Bootlooping.
There may be an alternative that will allow you to disable the little CPU cluster instead and not lower the GPU performance. I've not tried any other methods yet.

Multiple people have reported getting the boot loop of death while on Marshmallow. I think the idea that Nougat is causing the problem was discredited long ago, the fact that its a hardware issue with these phones is widely accepted and that the age of the phone is much more of a factor than the operating system you are running. Most of these phones are experiencing the boot loop of death shortly after the warranty expires, when the phone is 12-14 months old. Your phone is generating less heat since you ramped down the CPU which is likely why it isn't currently bootlooping.
Well...

You may be right but I didn't notice any Bootloops or random reboots until I upgraded to Nougat. After putting this "fix" in place my device still gets pretty warm under load but it doesn't exhibit random reboots or Bootloops... Heat didn't seem to be the issue since my phone would reboot into a Bootloop while just sitting on my desk at work with only background tasks running. Regardless, this workaround works for me and it may work for others.
Mine just reboots over and over, for days and days, my bootloader is locked and usb debugging is off.
HOW would one install APk from playstore if their phone can't even load up, aka bootloop of death ? You need to be more specific , like locked bootloader , unlock bootloader ..etc.... smh
Once battery dies what i have to do? (my phone dies two hours ago when I was with a 3% of charge and its bootlooping over and over) Full charge? Another thing?
Note:
1)I'm on the latest Pure Nexus build, stock kernel, unlocked bootloader
2)When i connect to the charger one hour ago the phone shows battery charge mode but stills bootlooping. I'm waiting to battery dies

Sorry that I wasn't more specific. My bootloader is unlocked and I'm rooted. Users may not need to be in order to get back the device's functionality.
It's a shot in the dark but if a user that is having the Bootlooping issue follows my steps, then they may get back up and running. I've yet to have another random reboot or a Bootloop since...

Since it's died, you'll need to power it on once it's charged for a while. When you power on and it starts Bootlooping, boot into the bootloader and follow my steps. If it Bootloops continuously, boot into the bootloader again and try to get into recovery. It will probably continue to Bootloop. That's what happened to me. I'd come back to it from time to time, boot to the bootloader, prompt it boot to recovery... over and over again. Eventually, it would fully boot up instead (not into recovery).
If it starts DON'T check messages or try to use your phone normally. Instead, follow the steps. Seriously. I made that mistake over and over again.
FYI: This process can take a looong time. Not days but sometimes it was hours until I figured my solution out. I don't know exactly how long it takes because I'd leave the phone Bootlooping and come back to it later in the day.
Many thanks!
Its work for my nexus 6p too
My nexus work normal in interval 1-5% of charge. If charge increase 11% - bootloop...
After enable powersave elementalx, charging to 100% and work well
I have a smartphone. Automatically went into reboot, but did not boot. It constantly reboots. First, the test is reflected that I've been unlocked by the bootloader, and then the Google inscription, and after that the smartphone reloads again. The recovery menu does not enter.
Thanks! Finally something that worked! The big cluster is indeed the problem. I had the porblem that the phone freezes and gets stuck in the bootloop when the battery is above 10-12%. I guess that the cpu disables the big cluster when you are underneath that threshhold(?).
One big problem I am still facing is that I can't reboot my phone and I have to make it discharge until I can boot it up again. Do you have have something that prevents that?
Big thanks again!
Still bootloops

I followed all the steps but my Nexus 6P still bootloops after crossing 10% charging. Is it possible for you to share your Kernel Manager settings screenshots please?
I too began to experience the boot loop issue literally 8 days after my warranty expired which was 11 days ago today! Have tried flashing several factory images from MM to N and even a saved backup I made from day 1 of having the phone. This method of disabling the big cluster thru ExK has definitely been the furthest I have gotten. Me and my friend(da guy) did find out that in order for the phone to boot up at all, the battery has to be at approx. 6% or lower. In that time is when you must quickly download ExK and activate power saver mode. I just called Huawei support and they did absolutely nothing to help me in this manner. I really do hope that this lawsuit wins in our favor. Speaking of which, does anybody know where we can check for status of this current litigation?
Update: Ordered a new battery and installed it... still bootlooping. This is very frustrating as i have been forced to use my ancient Moto Droid X2 as my daily
I wonder if someone could compile a kernel that always disables the big cluster for those with bootloop problems. Then you could just flash the kernel and not have to try repeatedly to get the phone to boot long enough to install the app.

I'll have to look into kernel building, but I'd imagine if you built a kernel that had powersaving as the default profile, it would work.
Got into recovery long enough to flash pure Nexus and root, but haven't been able to get it to boot yet.
Looking forward to one day being able to use it again. ?

I really want this to work. Can you please share your settings? I'm not getting passed 10-12% charge. It makes a loud noise and bootloop till around 6% but runs fine if it's below 10%. I can watch videos and listen to music
Same issue !
