Hi all,
I recently flashed CM13 onto my GRA-UL00 Huawei P8. Everything went fine until I noticed that there was no sound. I've spent about seven hours looking for a fix, and I've come up with nothing. I've noticed that I have no mixer_paths.xml file, and when I attempt to put in a new one, there is still no sound. I've tried a clean CM13 install, wiping everything and starting over, the latest Lineage release for Huawei P8, as well as reverting the ROM and Recovery to stock and running a clean install then. Nothing has worked, and my phone simply has no sound.
There is one other similar thread at the moment, started by Rome7643, who had one reply, from him, which was "Never mind, fixed it", with no explanation as to how or what he did.
Does anyone have any ideas as to what could've caused this, and more importantly, how to rectify it?
Thanks.
EDIT: I also JUST noticed that when the sound is enabled (that is, the phone isn't in Vibrate or Silent mode), the phone lags - it takes several seconds for it to register presses on the keypad, the keyboard barely works, sometimes it doesn't register my touch on apps. But if I put the sound back down to Vibrate or Silent, it goes back to work like normal.
For what it's worth, I messaged Rome7643 privately and asked him what he did to fix the issue. I'll post the fix here for posterity, in case someone else has this issue, Googles it, and runs across this thread as well. I want to give all credit for this fix to Rome, as he was the one who figured it out, not me.
Basically, the fix is to download a stock image (so the update.app file), and use the Huawei Update Extractor tool to extract the Image, Recovery, Cust and Boot .img files. Using Fastboot, flash them as you normally would, restart, and start the phone as normal. At this point, the sound is still not back. You now need to put the full update.app file into a folder called dload in the root of an SD card. Then, turn the phone off, and boot into the automatic Huawei updater by holding BOTH the Volume Up and Down buttons as you power on the phone. The phone should automatically begin to do a full, clean, fresh update from the update.app.
Rome said that he had to do this several times before the sound came back, but for me, the sound returned on the first attempt. I then reflashed the Lineage 13 beta build, and I had sound, and I flashed the Cyanogenmod 13 build, and I also retained sound. There is still an issue with the signal indicator, but that's related to the ROMs themselves, and unrelated to the sound issue.

Sometime last night, my AT&T G2 (D800) decided to go from being powered on and idling, to going into TWRP recovery mode. All by itself. I saw this, unplugged it from USB, and tried to reboot into system mode. But it simply won't do anything except boot into recovery. Powering off, trying to get to the bootloader, none of that works.
This is not a custom ROM, it's 4.2.2 stock from LG. I only rooted the phone, which was several weeks ago, and haven't had any problems, aside from TWRP not wanting to back up anything. I've been using Android since the original TMO G1 with JesusFreke's ROM, so I have a pretty good idea of what I'm doing, hopefully.
The only recent changes I've made are:
I updated busybox about 3 days ago (but have rebooted fine since)
I grabbed several legit apps from the market last night
Last night I also DL'ed, but did not apply, a ~50MB OTA update that has been pending. I don't think that would install without explicit permission anyway, which I didn't give it?
This phone was encrypted from the start. Maybe that;'s what prevents TWRP backups,, but right now I'm seeing TWRP errors/logs saying something like "Unable to mount \data". And yet I can browse to other folders, and see filenames in \etc for example. However, I don't see any files at all in \boot.
Since this phone has no external memory, and it's customized and has numerous configured apps, I really really don't want to have to wipe it. Although at this point, that may not even fix the problem? Even if it did, since I haven't been able to make backup images, it would be a Bad Thing™ either way. (Yes, I do have a secondary plan with Titanium, with backups going to cloud storage, but these are tedious and now a few weeks old. And wouldn't restore the ROM & system en masse.)
Please help.
Solved?
I'm not sure what caused this to occur, but I found somewhat of a solution after digging deep into my Google-fu.
I followed the instructions in this XDA thread and it actually worked. I didn't have adb access, but I was able to use dd successfully. It allowed me to boot into the device, unencrypt it, then arrive at the lock screen.
However, when I put in the lock code, it went apesh!t and played multiple notification sounds, with a blue circular wait symbol. It also flashed the LED from green to blue, as it normally only does during boot. Once I pressed the power button, I was back back into TWRP.
So then I followed Step 2 again, and once in the phone, I used terminal to run the dd command from inside the OS. This might be what it ultimately needs, because the prior attempt in TWRP had an error to the effect of "no space left on device".
I can't call it Solved yet, but it looks good to at least be able to get in and use the phone. I'm backing up with Titanium before I do anything else and will reboot and test its permanency later.
I'm gonna close this thread now that I think I have a handle on what is going on. The fix does survive a reboot, so I believe it's possible to repair the issue permanently per the instructions above. I also ran the phone for 3 hours with heavy app usage and no problems.
I believe what may have happened is my OTA decided to override my choice to NOT update the ROM, as some have reported in this Reddit thread. There's a lot of good info in that one, including how to stop getting nagged by turning the OTA notifications off, or to freeze it entirely with Titanium Backup if rooted.
Anyway, what apparently happens is that when the OTA/upgrade goes to reboot, and encounters a custom recovery, it gets confused... when you try to power cycle or reboot again, it sees the stock recovery still hasn't run whatever it wanted, so it starts recovery again Lather, rinse, repeat.
Fun times.
Verizon Note 3 here, I received the Lollipop ota today and thought no harm in taking it as I was already stuck without root on 4.4.4.
It worked ok for the first couple minutes, then a reboot, then same thing, about 5 minutes and a reboot. Sometimes ~2 minutes, seems using it in any situation made the reboots happen. I did a factory reset thinking that would clear things up. Unfortunately now it is even worse, as it's rebooting anywhere from the first touch to the screen, to about 15 seconds of activity, literally dozens of reboots.
I downloaded the update on my pc and installed via Odin hoping that the ota was just corrupted or some bad luck like that. Nothing changed at all.
It will idle after booting just fine, I just can't do much of anything, every touch of the screen feels like a roll of the dice. Every few reboots or so I can make it to settings maybe but haven't been able to actually change much of anything, not that it would seem to matter here.
I've flashed via Odin twice, cleared the cashe many times, factory reset 3 or 4 times. Am I screwed here? What else to try?
*UPDATE* I flashed back to 4.4.4 with Odin and no more issues. It appears that my device alone is completely incompatible with the new firmware.
I should also note that I tried airplane mode, safe mode, and removing the sd card with no improvements.
After hours of messing with this thing and nearly giving up, not half an hour after I post here for help, I seem to have found a solution, although hopefully not a permanent one. The problem was happening when I would touch the screen, not scrolling ever, but making selections. On a whim I turned off sound and bam, no crashes.
I would still love it if someone had some insight about this problem, or better yet a solution.
I'm not sure yet if it is just the keypress sound that is killing it, or all sounds. I never did have any issues with the stock keyboard clicks now that I think of it, only the menu press sound. In any case it's not every time it made the sound, just half the time or so. Anything anybody could add to this would be appreciated.
*Edit* Not a solution, but it did help.
Well it's not as stable as I'd hoped. More like before the first factory reset now, but still not good at all. The various sounds definitely trigger crashes quickly(menu options, volume pings, mp3 songs from sd card), but regular silenced menu presses do sometimes as well still. Phone also bootloops several times often before it can get booted stable and 100% always crashes immediately if I try to unlock the screen in the first 5-10 seconds after booting up. Not sure if I'll be able to call or text as it's too late to test that atm. I'll update tomorrow, any insight appreciated.
I would say a bad download but I don't remember if ODIN checks MD5 sums (pretty sure it does). I would do a full wipe and reflash the stock image with odin
I am 100% stock not rooted never been rooted 5.0 vzw and I have had a couple of reboots. Never ever had one on this phone before. My old note 3 was rooted but I got this replacement after the root exploits had all been closed.
ehh not all have been closed

None at the current time but CVE-2014-8609 seems like it could be some use
I spoke too soon when I said the phone was usable now. At best 5 minutes of light use as anything seems to crash it now. I did get a fresh image and used it with Odin with exactly the same result which makes me think its my phones hardware or something. Just seems crazy that it was working just fine before the update. The reason I pushed to 4.4.4 and lost root is because my phone suddenly started an issue where it would crash when making or receiving calls. It wasn't caused by any new apps or anything, just out of nowhere. I tried everything then updated as a last resort, carelessly I went to 4.4.4 instead of staying at 4.4.2 and lost chance of root, but it solved the problem I was having. I wonder if the issue is related somehow.
I was able to odin back to 4.4.4 and it's working fine so far, I assumed that you would not be able to revert back like the last ota and just tried it as a nothing to lose last effort. This is very important news to anybody that is having major issues with 5.0. Maybe, just maybe I'll try it again if they make an update patch for reported issues.
But for now, 4.4.4 it is for me.
VZW Note 3 update to Lollipop
I just finished the Lollipop update and my phone is working great for the past 30 minutes. Seems a little slower then usual but have had no issues besides my phone locking up after downloading the update, may have been due to my phone running down to 14%, but after removing the battery for 20 secs and putting it back on, phone came back on, I plugged into charger and started the update. Will post later if I have any issues.
I have been trying unsuccessfully through odin to downgrade but it keeps failing in odin, I downloaded the official firmware from sammobile.
Just curious if u r tried reinstalling newer odin? Try different USB port and cable. At this point maybe even try different pc if u have access to 1
So, I have gotten myself in a bit of a pickle I however think I can get out of it by sideloading using EXT. SD, Im not sure what to flash to solve the dillemma however. So this is the situation. I have a (had) a rooted Galaxy s4 (sgh-i337 ucufnc1) with 4.4.2 android. It had safestrap installed and back ups of everything else in sd card and other locations just in case. The phone was acting buggy, so I formatted the phone with safestrap, the problem persisted, ill get into the issue a bit further down. So I booted back into safestrap, and did a complete wipe, however my sd card must've bumped out, because it didnt delete any media files or so it said, and then after the wipe it crashed. and refuses to boot into safestrap or even past the splash logo. I can get into download mode, but usb debugging isnt on anymore since i wiped it, I can get into the other mode as well ( cant for the life of me remember the name of it atm although i use it frequently) with some luck. I also happen to have all .md5 files from a backup i did about 4 months ago in tact, I cannot for the life of me get them to convert properly to apply them to the phone without safestrap however, if anyone has any insight to this please let me know also.
I can/will list any other information I have if anyone needs it, and if anyone can help it would safe a life!
The reason i reformatted it to begin with, was because media would stall, and when i plugged in the audio jack it'd freeze the entire app using it, then the whole phone would freeze. I believe it was due to lucky patcher but im unsure. The issue began when I altered the auto update file, and even after i rectified it, it persisted. At this time i have a phone soft bricked because it didnt delete all the media files and I assume something bugged onto the kernel image but Im not sure. If I can simply try to restore it to stock kernel then im fine with that.

UPDATE: I resolved the issue, by rooting, safestrapping, ripping the image files, from another galaxy s4 with alike descriptions. then i managed to side load it, then it booted properly, i then reformatted it completely back to 100% factory everything. Now my original problem persists, and i cant help feel that google services is causing it. (examnples of issues" proccess.gapps has stopped. anotrher process error code. phone calls can be made, but not recieved as it seems the server is too busy to n otice it, massive battery drain, audio takes several seconds to play, while video continues to play fine, audiojack is mostly unresponsive, phone calls that are made cannot recieve or send audio during call session, phone may freeze at unlock screen, or any time during operation, may even reboot from process overloading" now keep in mind. i removed every system file and app that the natural reformat will allow. so nothing applied by the user is on the phone, other than natural factory applications. Im digging a bit into the phone as i can but its a slow process whenit starts freezing. if anyone has any idea of what can be causing this, or how to fix this please inform me lol.

The best solution must be installing the stock firmware via odin. Since you are on NC1 , You can installed the stock NB1.
Here is guide explaining you using odin, installing NB1, root with towel root, updated NC1, install the safestrap. The guide was not specifically written for that but you can find those steps in the guide.
I will attempt to do this, since nothing since has work. I am about to get a new logic board for the system in the next 2 weeks. Towel root DOES typically work on this system, however the last time I attmpted it it failed to work outright. Im not sure what has changed with the device, but i believe reflashing stock is the best method. The phone now, will boot up, then skip the lock screen and go straight to the home screen, which is black with no pull down bar, or with no signal and there is no way to rectify it. Even if there were, it boots back down and launches back up and becomes locked at the ATT logo.
After a fair bit of messing with it, and recovery mode it will sometimes boot normally where it tells me that processes has failed and askes me to cancel the ''app''. This is the best option to update the phone and attempt root, but getting it here is so difficult because it reboots itself and the mode is rare to acquire. This problem either is due to the kernel, or the rom i believe. I also am to believe the powercell may have some issue, as i replaced the battery a few weeks back and it worked fine for about 1 week.
Booting into safemode doesnt work either as it skips over the lock screen straight to the home screen. Outsidce of replacing the logic board, or attempting another flash im at the end of the short rope i was already on in terms of options.

UPDATE: I found therein two methods to flashback to stock. I did so, then proceeded to attempt to flash from nb1 to nj4. Progress stopped there when it flung an error 7 at me. So this means either something in my phone is corrupted or the file i downloaded from the above mentioned forum is corrupted. I also attempted flashfire, but seen as it STILL crashes at random due to process errors thats almost impossible to attempt.
A little bit of background.
Prior to this problem I was running dirty unicorns and elementalx kernel. Given that lately I had some freezing issues I decided that iro was time to update my ROM. Being the first time that I manually update a ROM and not having found anything online I thought (dumb decision) that all I had to do was to flash the most recent version. After I did that the phone did an app optimization (idk if that's how it's called, basically it optimised all the apps for the new version of the ROM) . After that the phone wasn't booting up, the dirty unicorns loading screen was running for half an hour and nothing happened so I restated the phone. When it asked for my sequence a message popped up "it looks like your vendor image is obsolete". The phone still wasn't booting up so I decided to restart once again and install the latest vendor image. After that the phone wasn't booting up so I decided to do a backup with twrp (version 3.0.0.0) and do a factory reset.
Plot twist the twrp decryption sequence (that worked 10 minutes before) now wasn't working so I had no way to access any of the phone's files.
Basically the phone won't turn on and I have no way of accessing it's files
I'd try a factory reset but there are some photos and whatsapp messages that are important to me and I'd rather not lose them.
Any tips?
Apologies for my terrible English

The best thing to do is this guide. http://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928/page384. Just go full stock without formating the internal. Flash twrp and see if you can get your photos. Next time back your photos up with Google photos if available in your area. Good luck

To update a ROM all you usually need to do is flash the newer version, but you also need to flash the newer vendor.img of the updated ROM is based on a newer Google build. Failure to do this is what caused the "it looks like your vendor image is obsolete" message to appear. I'm guessing you know this though as you went on to flash it later.
Not sure what happened with TWRP but you've done something else wrong at some point. Best idea (as pointed out above) is to flash the factory images. You can try it without formatting userdata in order to retrieve whatever it is that's important on your storage, but once you've retrieved whatever you need (if you even can) you'll need to format it because you really need to start fresh.
I've been given an OP2 64GB as a project from a friend to try and return to stock and working. It was running a custom ROM which wasn't working particularly well, so I did the full reload to stock 3.0.2 via the Qualcomm download described here by @fareed_xtreme which downloaded okay, booted up, and the touchscreen seemingly didn't work. I've come across that before where there's been driver or firmware mismatches, but then I realised that if I held my finger on the screen for between 2 and 4 seconds, it'd start responding, right up until I let my fingers up off the screen. I could do multiple scrolls by adding a second finger to the mix, and it'd keep responding until I let go, at which point I'd have to hold down for another 2-4 seconds to make it do anything. The digitiser is fine, I enabled the overlays in dev tools (painfully clicking item by item!), and it shows the traces fine. They don't show up at all as screen presses until said delay happens, which is very odd. It also responded fine in the recovery, which was plain odd.
After a while, I tried returning it to 2.2.0 courtesy of @fareed_xtreme's other guide, which then worked fine, booted up, had 2.2.0 installed, touchscreen worked fine. Did notice the baseband version claimed it was unknown, though I'm unsure if this was related to me having no SIMs in it. It did initially offer me an OTA upgrade to the latest Marshmallow, which I allowed it to do, and promptly had the same issues again.
I've tried flashing various ROMs - Resurrection Remix etc, to find they've got the same problem. Any Marshmallow-based ROM seems to suffer from this weird input lag. The capacitive buttons are fine, it's just the display. Also, weirdly, it works if I touch the screen just as I wake the phone with the power button - so I can hit the power button and immediately swipe the lockscreen off, but then it reverts to the previous behaviour.
I've tried re-flashing the firmware for the various ROMs (matching with the installed ROM obviously). I've also repeatedly wiped the system/data/cache partitions etc, and have backups of EFS via TWRP saved off the phone. I also spotted two threads on the OnePlus forums describing this exact issue here and here, both with no solution. I also noticed people have had similar issues long ago when they tried installing H2OS and then returning to stock, without doing the full qualcomm download, but they seemed to be mostly solved with the full ROM reload and a cache wipe.
My next step is to flash back to 2.2.0, and incrementally upgrade with the OTAs, see if it works, but I suspect the second I make the jump to 3.0.2, I'll lose the touchscreen again. I've left it OEM unlocked, and got TWRP and original recoveries available.
To be honest, worst case, I just reflash the phone back to the final 2.x version, at least it actually works then, but... I'd really love to know why I can't fix this, and what the actual issue is, if anyone out there knows. There doesn't seem to be much on here in the way of people experiencing the issue - either that, or my search-fu has repeatedly failed me. My gut feeling is something kernel/driver related, but I don't understand why it wouldn't get fixed with the full firmware download via QC.
Help me, XDA, you're my only hope!

I would suggest you to open a ticket with OnePlus Support (Live Chat). Inform them of the touchscreen scenario (Do not mention about the Quallcomm Flashing or they may start giving you a hard time for taking matters in your own hands). They will schedule you for the process and hopefully, they may be able to resolve it possibly with a newer Stock Reset.
Cheers, I'll give them a shot!
Unfortunately got no dice there - they reflashed it with OnePlus2_14_A.27_161227 (annoyingly, didn't get the decrypted files due to a screwup with my file mirroring), but still had precisely the same issue, up-to-date, no working touchscreen. If I can't get it working, it's not the end of the world, it's more annoying me that I can't figure it out... suggestions of a ROM to flash that might work would be most welcome!
