Sound and mic dead after phone crashed. - Nexus 6P Q&A, Help & Troubleshooting

Had a strange issue happen just a little bit ago figured I'd post something about it and see if anyone else has had a similar issue happen.
Was stock system-less rooted bootloader unlocked fastboot flashed to MHC19I ota.
Anyway.. My phone's audio sudden stopped working then a few moments later crashed and rebooted, Upon rebooting I tried to use google now and noticed my mic wasn't working which i thought was odd so i did a hard reboot.. and when they phone was back up and running the mic still wasn't working so i checked my speakers and they were also dead.. you tube would tell me an error occurred when trying to watch a video and google now would tell me it couldn't open the mic. I tried everything to fix it.. factory reset.. booted into twrp tried to clear cache/ fix permissions etc nothing worked. I just flashed the google factory images and relocked the bootloader () and I got it working again.. but im just wondering what could have caused such an issue considering i was stock everything with only a systemless root?

[Q] Sound issue and bootloops on my i337

Hello everyone
I am having a strange problem with my phone.
The problem started a few days after the Ota update to 4.4.2 NC1 (may not be related)
The sound on the phone the speakers the touch tones the ear phones everything just used to go off randomly. Initially a reboot used to fix it. But progressively it got worse and phone would get stuck at att logo.
Initially tried a master reset and it resolved the issue temporarily a few days after it was back to its old tricks.
Then I tried to refres stock with Odin and the behavior was same, works fine for a day or two and then no sound and then boot loops.
Yesterday I tried to install hyper drive room with safestrap. It has lost sound couple of times, but till now reboot has fixed it.
Could you guys please help me on this as I have spent couple of months on it and now it's messing with me
Thanks in advance for your help

apps crash, phone reboots

I had been using rooted kitat for sometime. Everything was great. Then I installed a 5.0.2 Russian stock ROM and that ran fine too. But after a few weeks, I have been getting this problem. It seems the phone doesnt load apps and/or they keep crashing. The phone eventually hangs and reboots, and even gets stuck in a bootloop at times..I have tried flashing alternative roms through odin, i cleared the cache and wiped data through recovery but the problem persists...most of the apps that are glitching are google apps and sometimes systemui and phone....What else can I do?

im having the same problem on my G530H. does anybody know how to fix this???? its really annoying
Maybe you didn't factory reset before update to 5.0.2

Help - G935A stuck on AT&T Logo - 3 vibrtations

For a week my G935A worked fine... direct out of the box I flashed ENG Kernel and Rooted, then installed apps and configured - no issues.
Today it was working then it hung on wake.. I tried to reboot and now it gets stuck at the AT&T logo and vibrates 3 times - over and over
I can get to Odin and Recovery screens easily so I tried to flash the ENG Kernel again & deleting Cache Partition few times - didnt fix it.
Also tried booting into Safe Mode - it never gets there, stays at AT&T logo.
When I go into the Recovery menu, I see at the bottom, in red... "dm-verity verification failed"
Anyone know how I can recover from this without Factory Reset? It took 6 hours to reinstall and config all my apps - really want to avoid that.
thx for the help!
as far as I know there is no way to fix and save your stuff. I had the same problem with G930A and even doing a factory reset would only allow my phone to boot but then I get apps crashing and then a reboot puts you back at ATT logo and the vibrates. Best to ditch the whole engboot and go back to stock until a more stable rooting method comes out.
Some searches shows posts that say using Odin to flash HOME_CSC without having to wipe and everything survive
... Where can I get HOME_CSC? I dl'd stock rom and dont see it in there.
thx!
Same here this morning on my 930A w/ PK1....went to watch a youtube vid and everything google related began crashing.
Only been on engboot for a couple days but did flash the v15 debloat last night. hmmmm.
Any luck with the files or procedure LivinOne?
Update: Flashed the PK1 CSC and got into recovery.
Wiped cache and reboot, same failure mode....sad face.
Flashed CSC again, into recovery, factory reset, wiped cache.
Back to setting my "new" device up.
Dec 30 update: Same crash, SEMI same problem.
I get the single vibration followed by the 3 vibrations after I put my pin in from a restart.
Same symptoms prior, all background activities began crashing.
Running all PK1 files from QRhinehardt post.
Any thoughts?
I ended up wiping and flashing the T-Mobile firmware and using the ENG bootloader (but not rooted yet). It is WAY faster than the AT&T was. I've only had issues with Wifi Calling (it doesnt seem to work most of the time)

Hi, did you first flash with eng bootloader and then tmobile rom? I miss this step...I appreciate your help please
Single vibration followed by the 3 vibrations
Hi, were you able to fix the problem? I'm also getting the single vibration followed by the 3 vibrations.
Do you know why is this occurring? I performed a wipe cache and factory reset but still nothing.

my Mi Note is dead.

Hi everybody.
Dis morning I woke up and I realized that my phone was gone. I used AOSP Extendend ROM when it happens. At first, the rom completely froze. I thought it was a bug, so I rebooted the phone, but after did dis, the phone kept on rebooting and froze on first screen and I couldn't do anything. Touch didn't respond, nothing worked.
So I tried to go on recovety, but nothing.
At the end, I gave up about take back my data and try to install the stock ROM through MiFlash. I tried different stock ROM, but at the first they works, but during the installation guide they froze again and reboot. I can't even finish the setup!
So I tried again, unlock bootloader, flash TWRP, but still there:
- only TWRP v2.0 works, other versions won't start
- even with TWRP v2.0, after did wipe everything and format, when I tried to install a custom ROM, even TWRP froze and reboot the phone
- TWRP is pretty useless, it keeps on froze and when I boot recovery again, TWRP is locked and I have to format everything again, but still don't work.
Someone could tell me what happened to my phone? Any suggestions about what I could to to install something on my phone?
Pls help me, I am completely lost and disperate
You may in deed have a serious hardware problem.
What you can do without opening it up is to try charging it overnight, and see how it works tomorrow.
You have tried everything else you can think of, I assume, like wiping & formatting everything you can in TWRP, and possibly "repairing file system" if there is such an option.
The next thing I would try is opening it up and disconnecting the battery for a while, then connecting it again to see what happens.

Ok, I will listen your tip. Yeah, I have tried everything but nothing. Technically, I bought this phone last december, so it's still covered by warranty, but I have to send it to China, I would avoid that if I can.
I hoped there would be something that I didn't but...nothing.
Thanks anyway dude

XT907 bricked (probably partitions in read-only)

Good morning.
After almost 3 years with no problems with a XT907, I have again an issue with it (this time, my father's one). Again, I come to you requesting help.
It all started with all apps crashing over and over. With an old XT907 I have for emergencies, the common fix method is flashing VZW_XT907_4.4.2-KDA20.62-15.1_1FF.xml.zip with RSD Lite v6.1.5 and all solved.
I tried that method with my father unit, and when it started again, all process were still crashing. I thought it was still nothing (just a harder issue), and tried flashing VZW_XT907_4.4.2-KDA20.62-15.1_CFC_1FF_SVC.xml.zip, just deleting all his data, to fix it.
When the process ended, it turned on and it had still the same problem. In this point, I got worried the /system and /data partitions got locked
I re-started, went to stock Recovery, and wiped system and cache. Then, went to Fastboot a third time and tried again flashing VZW_XT907_4.4.2-KDA20.62-15.1_CFC_1FF_SVC.xml.zip. Guess what? Still the same problem
The phone turns on, but ALL apps keep crashing over and over. I can't even take an screenshot, as it immediately reboots.
Someone know what happened with it? And... how to fix this issue?
