[Q] Nexus stuck in reboot loop (what to do?)

I felt my nexus reboot during class today(it was in my pocket) and then it got stuck in a reboot loop, it freezes during boot animation and starts over.
I have tried to pull out the battery, to do a cold boot as well.
It is rooted, and i followed one of the early tutorials to do so (i don't remember exactly which).
Is there anything i can do without loosing my data(no backup, i know,stupid me).
Can i try to reset the bootloader for example?
I have also received 3 system updates the last week, assumable from samsung, (yakjuxw). But it hasn't increased my android version. I don't know if this has anything to do with my problem, but i feel like i should mention it.

+1 on this too...i was checking my messages this morning and it just rebooted. havent had this ever happen to me, no matter wiping, reflashing, restore....nothing works...just keeps rebooting at google screen 4 or 5 times...then it just stays on the screen, phone starts to heat up too.

Same here, I installed Chrome bate last night. Did you guys do the same? I wonder if it is the cause of the problem.

i did try out chrome beta yesterday, but ended up uninstalling it. im on a ir10 modaco kitchen rom with a 1.35ghz oc custom kernal.

I am on stock rom without root.
I found the below and it scares me. Looks like there isn't any fix...

Can you access the bootloader?

i am pretty sure if you reset the bootloader it will wipe everything. just go into recovery and do a factory reset (last option of course).

I installed google chrome earlier today aswell.
I have now tried to restore from an earlier nandroid backup, but it fail at the \data stage.
Factory reset didnt help either.
edit:
However, i was able to pull data using adb. Saved my images atleast.
also: i have clockworkmod v5.5.0.2

Do you have the SDK installed on your pc? If so, you should connect it and run ddms. You can then watch the log and see where your phone is crashing. Maybe that would give a starting point to what is wrong.

I start ddms, and my phone pops up under devices witha nomber as name, ther after '??' and 'unknown' nothing else. This is when my phone is in clockworkmod recovery . it disappears when i try reboot.

Hmmm that's weird. You might have to try flashing the stock images in fastboot.

Did I just brick my phone? H815 + Root + trying to FlashFire XPosed

Phone is H815 TWN. Rooted but not unlocked.
Updated the phone to 10e via Download Mode - Check
Tested phone - Check
Xposed wasn't loading - Okay, must re-flash framework
Starting flash with FlashFire and it's been sitting at the LG Lifes Good boot screen for 15 minutes...pulled the battery...same thing.
I did do a system image backup before flashing 10e...is there a way to restore that via Download Mode? Is it the same command just change rootedsystem.img to system.img?
Any help would be appreciated.

I went ahead and repushed the backup I took via Download Mode and phone is booting now. I guess I'll try my process again.

Maybe you should delete all of the files you have from trying to install xposed and start fresh. Reread each step and make sure you have the proper files in place. Also, xposed took upwards of 15 minutes to install for me. About half way though, the screen turned back on for a quick second and showed some of the installation process, but promptly shut off again. Make sure you have sufficient battery and don't even touch the device, but keep an eye on it. No screen taps, no device rotations. Just let it do it's thing and be patient.

I've done this before, two times. And I'm a systems engineer for a living. Would like to think I know what I am doing lol.
The Xposed framework (and apk) are both files I've used in the past without issue. I keep them saved for re-use in cases such as these. Perhaps something just went wonky...before the LG logo being stuck for 15 minutes...I was in theory at like minute 20 of the process (it's taken around 15-20 the other two times I flashed Xposed so I knew going in it would take a while). 100% battery (just put a fresh spare in), nothing connected.
For S&G's, I'm going to attempt to do the framework install with the v78-SDK22 version for ARM64. We'll see if that has a different result.

I've actually just updated to v78 like four or five days ago and I've noticed significant improvements. I also kept my old files around for the xposed installation and when my phone bogged down, I did a factory reset and flashed those same files. They preformed poorly causing me to do another factory reset. I deleted all my old files, updated to the newest version and things have been great ever since.
Best of luck to you.

Good to hear that v78 is working great. Starting that process shortly

Looks like all is well. 2nd times a charm tonight.

Help - Galaxy Tab S 10.5 Bootloop Out of Nowhere

So...
Last week, my wife's Tab S went into a bootloop. She runs complete stock, we haven't rooted, or anything. There had been a notification about an update, but she hadn't touched it. She'd updated to Lollipop at some point last year, but hadn't applied the absolute latest update. One day last week, she just turned it on, and it started bootlooping.
Because it was so stock, there were no backups, no nandroids, or anything like that. No Custom Recovery. I told her "well, we can just do a factory reset. You'll lose everything, but once we get you back up and running, it'll just re-download everything from the Goog." So we factory reset it. Looked good for a minute, booted into the first screen, enter in your Wi-Fi password, all that. As soon as we got the Wi-Fi password entered, however, it re-booted. And keep rebooting. Bootloop city. No problem. I walked her through (over the phone) using Odin to flash the latest Lollipop firmware. No dice. It appeared to flash successfully, but still bootlooped.
Over the weekend, I tried using Kies to flash the most official firmware I could find. Everything was successful -computer recognized the device, was able to download "direct from the source," as it were, but it got stuck at 69% twice before failing. I read somewhere that one had to run Kies in administrator mode to get it to successfully complete. So I did, and it got past 69%, successfully completing the flash. STILL NO LUCK. STILL WITH THE BOOTLOOPS.
Last night, I realized that I hadn't flashed in Odin using Administrator Mode. Tried it, using latest 5.0.2 (XAR-Cellular South). Flashed successfully, all appeared well. Still bootlooped.
So, I'm stuck. I can get into recovery, I can get into Download Mode, I can successfully flash. I just can't get the darn thing booted.
Thoughts, anyone? Should I try flashing a Custom ROM? How hard is that using Odin? Thanks in advance.

Ok this will take a few tries but here is my method of dealing with this situation
1) Flash stock using Odin
2) AS SOON AS the screen goes blank, start holding Power+Volume Up+Home
3) When recovery boots, release the buttons
4) Use the volume buttons to select "Wipe data/factory reset"
5) Press power to confirm
6) Reboot
If that doesn't work, you may either:
1) (more likely) Installing a ROM will fix the problem
2) (unlikely but possible) You might have worn NAND pages, which I doubt but could cause this behavior.

Thanks, I'll try these steps tonight when I get home, and report back!

All right, here's something interesting. Before I tried your first step, I remembered that the other night, I left it stuck at the Samsung logo -it was just kind of stuck there, and since the behavior was a little different than I'd seen before (not continuous bootlooping), I thought I'd boot into recovery and wipe. I did, I wiped (factory reset), and rebooted. The tablet booted into the first screen, Accessibility/Wi-Fi, blahblah. This was where it usually rebooted. On a hunch, I bypassed entering in my WiFi key. I then bypassed almost everything else (Samsung account, Google account, etc.), expecting that the tablet would reboot at any moment. But I made it to the front apps page, where it shows you the side-launcher, the Magazine-Flipboard thingie, and whatnot. Wi-Fi still not connected, though. I opened up the app drawer, and scrolled around. Looked really good for a moment. I even took a picture with the camera, and viewed it in Gallery! Feeling brave, I thought, "well, maybe it just needed a couple of minutes before firing up the radio." So I went into settings, and inputted my WiFi key. It connected. And rebooted into its bootloop. (getting so tired of that boot-sound).
Went ahead and flashed the most original stock firmware I could find. As always, flashed successfully. As soon as it booted, I made my way to recovery, and wiped, per your instructions. No luck. Bootloop again.
It's something in the WiFi is what I've come to think as a result of the above. Which I don't entirely understand, as I thought the radio got re-flashed with the firmware.
I'm ready to try flashing a Custom Rom. Can I do that through Odin, or should I try and flash TWRP, and do it through there? Will TWRP flash without a working (bootable) OS?
All right. Thanks for your response!

Try this as a test.
First make a full backup of every partition with twrp including the EFS <<IMPORTANT!
Get it booting again without wifi then root the device and delete the EFS folder or delete it in recovery.
Reboot the device and try and enable wifi.

Got TWRP installed. Won't backup. Fails at 16% (system partition, I think). Just powers down to battery indicator in the middle of the backup. Looks like it backs up the EFS, though, since it's the first one. And when I go into TWRP's Restore option, there's a backup there (though I don't dare try and restore it).
Now I have to figure out a way to get the Custom ROM and GAPPS I downloaded onto the tablet without a reliable boot... It's gotten to the front screen a time or two tonight, but starts looping even when I bypass the WiFi setup.

Entered adb/TWRP interface. Tried to push two files, a Custom ROM file, and a GAPPS file. The ROM failed, with some sort of "Error 7," incompatible data, blahblah... Just out of curiosity, I tried to push the GAPPS file, and that failed after about 6%, and the tablet powered off.
I'm running out of ideas.

copied a custom rom to a USB/OTG stick (thumbdrive), and plugged it in. Fired up TWRP, tried to install. Wouldn't. Wouldn't install GAPPS, either. Looks like the only way it wants to flash anything is through ODIN or KIES.

The Latest...
All right...
I remembered that sometimes the TWRP version mattered. When I installed TRWP last night, I installed the latest and greatest, 3.0.2. Last night after I gave up, I remembered that sometimes, the latest and greatest TWRP doesn't install things perfectly. So, this morning, I downloaded TWRP 2.8.6-ish onto the USB/OTG device, and re-flashed the recovery partition. To be honest, I was surprised that TWRP was even able to flash that (but the TWRP image is only like 9.8 MB, so...)...
Got TWRP 2.8.6.0 flashed, and rebooted into TWRP. Immediately decided to try and re-flash the custom ROM that I'd tried unsuccessfully to flash last night, since the thumbdrive was still plugged in. Resurrection Remix Lollipop. Lined up GAPPS in the queue, as well. The ROM *appeared* to flash better than it had in TWRP 3.0.2, but it was sort of hard to see... GAPPS failed, and I was prepared to watch another round of bootloops. It did bootloop, sort of. The RR splash screen appeared, said that it was installing (or preparing) xx out of XX apps. Then, it rebooted. I figured it was doing its bootloop thing. However, it got to the same screen, "installing xx out of XX apps. Except that XX number had gone down, and the xx number had gone up. It repeated this action about 4 times --the last time I saw it reboot, it was "installing 1 out of 2 apps." And then...?
It booted into the RR lockscreen.
Of course, there were no GAPPS. In fact, there are something like only 20 apps total on the tablet. But it appears somewhat stable at the moment. (See picture).
Afraid to try and connect WiFi, afraid that it'll just bootloop.
Speaking of bootloop. At one point, once we got it booted, my wife hit an option in the Settings. LCD Density, I believe. As soon as she hit it (she literally just placed her finger over the 320 default option), the tablet rebooted. No loop, though. Rebooted straight back to the RR lockscreen.
So I appear to have a somewhat stable OS flashed onto the tablet at the moment. No GAPPS, though. No WiFi.
Anybody have a suggestion on where to go from here? I have my doubts as to whether or not I can even back up this configuration.
Sorry about all the updates. I kind of figured that if *anyone* else ever goes through what I'm going through, they'll have some sense of all the different things that can be tried in resurrecting a bricked/bootlooping device. I appreciate everyone's efforts to date -thank you so much, @Lightn1ng and @ashyx.

All right, because I can't leave well enough alone....
I got WiFi up and working. Tablet still stable and working. Wheeeee.... No GAPPS, though.
Downloaded GAPPS, second-smallest package from opengapps- only 128M (5.1 ARM package). Downloaded it in Android, from the tablet! Tried to flash it in TWRP. Failed, tablet rebooted halfway (not even) through. Now it's bootlooping again...
I should've left well enough alone, and waited for someone. Have tried re-installing Resurrection Remix, but tablet keeps failing to flash. Might have to try and flash a different TWRP. I don't know...

Have you tried another Gapps? Also, is this the WiFi only model or the LTE model we're talking about?

It's the WiFi-only model - SM-T800.
It's kind of weird. I thought it might be some sort of internal memory problem (like the worn Nand pages you mentioned), since almost anything I try to do in TWRP fails (although I was able to flash an entire Custom ROM the one time AND get it booted) -but backing up isn't working, whether it's to internal/external SD. And the fact that I can flash perfectly (subjective term there) well using Odin or Kies tells me that whatever problems the tablet is having, something's getting through.
I'll try a different GAPPS package. Right now, though, TWRP isn't letting me flash hardly anything, and moving files back and forth on this thing is just awful.
AGH - I was so close!

Maybe somebody else with a T800 could backup their entire EMMC using
Code:
dd if=/dev/mmcblk0 of=/sdcard/full_nand_dump.bin
And you take the file on your tablet and do
Code:
dd if=/sdcard/full_nand_dump.bin of=/dev/mmcblk0
And restore YOUR efs folder using TWRP.
THIS IS A DANGEROUS OPERATION AND I AM NOT RESPONSIBLE FOR ANYTHING THAT GOES WRONG!

@ashyx Any more ideas before I go ahead with my evil world domination plan to recover this device?

I wouldnt carry out any risky operations until a full backup can be made with twrp or you may end up with an unrecoverable device.
If twrp cannot backup the system partition then there is an issue with the partition.
Try backup again and post the recovery log, it may contain some relative information.

I have the same issues and have tried eveything. I was rooted and running the latest Pheonix rom on my sm-t800. Last Wednesday (8-10) I starting getting boot loops out of nowhere, no new apps nothing just a daily driver. I've been through everything on here and have gone back to bone stock but to no avail, the boot loops just keep coming. I can connect to wifi and get things set up but if I try to use anything more than 'light usage' the tab starts its boot loops again and rows fits for about 10 minutes and always different timing on the boot. Sometimes it will make it to the Samsung logo, sometime only to Tab S and sometimes about 10 seconds of usage.. I know this isn't helping much but wanted to let you know there are more of us with the same problem. Will be blab to try anything to help said issue.

Exactly the same issue on my LTE version.
Samsung support just asked me 230€ for a new motherboard.
I refused to repair. I think it is related to nand memory..

Hello I have both the 8.4" and 10.5" I updated the 8.4" to Android 5.02 nothing but boot loops my other is still on 442 and I wont be updating it as its working fine. I have been reading a few posts and the problem was right in front of me all the time I have 2 internet connections 2.4 GHZ and 5.0 GHZ if I connect to the 5.0 GHZ I get boot loops but if I stay on 2.4 GHZ no problems what so ever so I may just install a custom rom and my 10.5 tab and stay clear of the faster internet.

Hello,
and the rest of story??
i can flash TWRP in download mode, and i can intall zip by TWRP , the lineage rom,
but, cant odin flash official md5 file, it stucks on logo.

[Q] Root Issues - Are these known? Are there fixes?

I purchased my Pixel 2 XL from the Google store. I had just upgraded to the 8.1 OTA a few days before when i came across this video and used it to root my phone:
https://youtu.be/nFD9sa-WdUM
Here's the basic steps i took:
Unlock dev options and turn on OEM Unlocking
Boot to stock recovery
Go to his highonandroid site and download TWRP 3.1.1 beta2 (img and zip), an outdated fastboot.zip, magisk 14.5, and the USB drivers which i didnt download because my computer is already recognizing my device just fine.
Extract the fastboot files to a new folder and copy the twrp img file to the fastboot folder.
In CMD, unlock the bootloader with fastboot and reboot phone.
Connect phone as storage device, copy over twrp zip file and magisk 14.5 zip files to root folder on the phone, reboot into recovery
Use fastboot to boot the twrp image that we copied to fastboot folder to get into twrp
Unhook the USB cable, set TWRP to read only, install TWRP, hit home button, then install Magisk and reboot
Once booted up, get into Magisk, download proprietary software, run checks and done.
Once this was done, my fingerprint scanner and wifi no longer worked. I could turn wifi on but it would never find anything. I also received the error when rebooting the phone that says "There's an internal problem with your device. Contact your manufacturer for details." When this message is on the screen, if i dont touch the phone and the screen times out, it flickers really bad and never actually shuts off until i unlock it and hit the OK button.
So i decided to give it another go and ran into some big issues. I figured that i used 8.0 instructions on 8.1 and there was enough things different that it caused problems, so i used this link to reroot:
https://forum.xda-developers.com/pixel-2-xl/how-to/guide-unlock-flash-root-pixel-2-xl-t3702418
I went through the first 10-15 pages and the last 10-15 pages and did some searches on the thread and never found any of my issues, but found that a lot of people used different sets of steps and pretty much everything was successful as long as you didnt miss anything and used the most updated stuff. So i did, i went to googles website and downloaded the newest SDK with fastboot, adb, and all that good stuff, as well as the newest 8.1 image (there was a newer version but it had a carrier label on it so i didnt get that one), and the newest magisk and twrp.
I flashed 8.1 and the phone wouldnt boot, nor would it get into TWRP anymore, so i had to use fastboot to boot the twrp image and reinstall the recovery and magisk but it still wouldnt boot. I ran through several different steps and eventually got it to boot up with recovery working. Its the newest 8.1 image, the newest magisk, and the newest twrp, and since then magisk has updated a couple times.
Now on to my issues!
I still get the "Internal problem" popup when booting
I get a lot more random reboots
Sometimes random things just wont work, like streaming plex to my tv or loading an app or something on an app and i have to reboot and it works fine
I've seen numerous times that the "Internal problem" thing is just a mismatch between the system and vendor build.prop files. I dont know what exactly is mismatching between the two but i've tried reflashing them and all sorts of things and nothing ever fixes it.
Does anyone know if there's a fix to any of these three issues, or if maybe looking at my steps i clearly did something wrong? I'm willing to do the whole thing over again if there's a good suggestion, but once i flashed the 8.1 image and went that route, i rerooted successfully 4 times total before i quit doing it again just because of that internal problem popup, i kept figuring something went wrong or i did something wrong. I had no security or anything set before rooting or flashing or anything, and each time i reflashed the operating system, but when i flashed the OS, i had to extract the system file because i would constantly get an error that it was too big and it failed to truncate it, so i've always had to manually install it by first copying it to my phone and installing it through TWRP. Its been an adventure, but these problems suck!

It's called training. For the error, you just need to fastboot flash the stock dtbo.img. This was fixed on the 15.1 version of Magisk so you shouldn't have that problem anymore. I can tell you that rooted, kernel and a few root apps and I have never had ANY random reboots, so one of your apps is causing it or you didn't start from a completely blank slate. Run your phone in Safe Mode for a while to see if you stop the reboots 100%. If so, one of your apps is the cause. If you still get reboots in Safe Mode, you're gonna need to re-install. I suggest using the instructions on the Google web page where you got the full image. (and try to distill your posts down a little, ffs)

My concern here is that my settings and apps are literally exactly the same as before root, except for magisk, its my only new app, which would lead me to believe that something Magisk is changing is causing the problem, or something else is happening that i'm not realizing yet.

Run your phone in Safe Mode for a while to see if you stop the reboots 100%. If so, one of your apps is the cause. If you still get reboots in Safe Mode, you're gonna need to re-install. I suggest using the instructions on the Google web page where you got the full image.

The reboots are typically 1 reboot every 1 to 3 days, so its not a terrible issue but its happening and it shouldnt. For flashing the OS, after the first failure when trying to install it, those are the only instructions i've used, but i get that error when trying to install the OS that says something about how it failed to truncate the system.img file and so it wasnt installed, so my work around was to copy the file to the phones root folder, install the 8.1 image then immediately go and manually install the system.img file in twrp since its the only thing that fails, but i still have issues. What is this truncate issue?

I agree! hahaha i just wanted to be clear and include all the details, otherwise everyone would have asked me question after question that i could have just included. It ends up being long, a lot happened!
I'll give that dtbo.img a shot and see what that clears up, then if there's issues with rebooting still i'll try safe mode for a few days and see what that does.
Thank you v12xke! (how do you pronounce that? haha)

Your dtbo.img got patched by Magisk somewhere along the line and that is why the OS is throwing the error. Extract that img file from the full Google image and fastboot flash it, and the error will go away. There is a long thread around HERE on random reboots you should read. The v12xke is a car (Jaguar E-Type) I once owned.

So i just tried to do this and ran into one of the issues i had when originally trying to root it... I get into TWRP and it will not take any button presses, like the touch screen has become a screen (minus the touch). Is there a fix for this or do i just need to install TWRP before i use it each time it does this?

1. You don't use TWRP to flash dtbo.img, you fastboot it while the phone is in bootloader mode.
2. TWRP works just fine if you install it and leave it installed. Make sure you are using 3.2.1-0 (img and zip).

I was getting into TWRP to create a backup of everything and it popped up asking for my password, and i remembered reading that we have to get rid of all of our security before making a backup, so i tried to hit buttons to cancel it and nothing worked, i had to hold the power button. So i eliminated all of my security and went back thinking it was a 1 time issue but it happened again, it took me straight to the main menu but nothing would work. I'm using 3.2.1-0 like you mentioned and i cant press any buttons. I'd like to back everything up before flashing this or anything else.

You don't need a backup before re-flashing the STOCK dtbo (or boot) partitions, haha. READ UP.

Can't boot TWRP

So, I went back to stock ROM so that I could update to Oreo, and I still have 32bit twrp installed. But when I try to launch it, it freezes on the loading screen. That also happens if I start my phone through bootloader. Was planning on going back to Custom ROMs, Android Pie this time, and flash Viper4Android.

If you are telling after entering the password it loading then it going to take a few minutes to decrypt the data after that it will work normally,but in some cases it hangs/freeze for some time but then also it work again.

Thanks, that was it. Took 7min to boot, and first time I noticed that my phone was also in a bootloop which was magically solved so. Now I'm trying to figure out why my microSD's files/folders show up as 0B files, some randomly since there are still folders but with 0B files/folders turned into files inside them. Installed
latest AOSP Extended and Pico Gapps.
It's a 64GB exFAT one, used to work just fine. In fact everything's fine on my PC. My other microSD, 32GB fat32, works just fine.
