auto rotate gyroscope sensors not working

Hi, I recently flashed a jellybean in Rom on my HTC one x and the rotation stopped working. So then I decided to return to factory settings with an ruu. So I did that and it was functioning again. So I reinstalled jb still worked.I then decided to try the 4.2 camera on my one x and it stoped working again, I then tried the ruu but this time it did not work. Next day I go home from class decide to unlock and relock the bootloader and it worked again, I then tried to install a in Rom ( once again) but this time it did not work. So I tried the ruu again, didn't work, tried unlock and relock bootloader, factory reset, wipe cache, everything and yes screen rotation is on. I alsotried the app android sensor and it showed my accelerometer/gyro not working. Can someone explain how to fix because its hard for me to believe that its hardware since it happens after I install a Rom or flash something. Please help.

That can happen from time to time with gyros. Even if you get it to work with the right RUU, then you reset the device, it might stop functioning again. I'd say your motherboard needs to be replaced. You can always try with different ROMs and stuff but my thought: your HW is problematic

don't think so, every person who encountered errors like this were on cm10 and its kernel ncx, theres should be something wrong with those things... or people don't flash it correctly
I have this problem as well, but I'm using ARHD rom, right now.
Although I also think it's more a hardware fault, I'm not really 100% sure about it.
Sometimes a new Rom flash or a reset can fix it.
But after a few reboot it gets stuck again :-/
So confused about this problem too
Although, my phone is unlocked now and got Hboot 1.33. I'm gonna wait till the official RUU is out and reset my phone fully (with locked bootloaders) before sending it to HTC for repair.
Maybe you should do that too
I had this problem too. It was fixed for a while after I flashed stock rug but then I clashed another recovery and wham they got knocked out again. Then I installed viper, cm 9 still not working. Installed latest paranoid android 2.53 and they are working again oh and I have latest twrp recovery installed. I really can't say if it is hardware or software. Maybe a mixture of both. I dunno. Only just flashes pa this morning but I have rebooted and they still work. Usually it will get knocked out if I reboot so I'll see what they are doing after a week or so. I'll probably keep pa on here until my official j b OTa is released. I think it did have something to do with either that ncx kernel or a recovery I tried. As that what knocked them out each time. Good luck in fixing it as different people gave had different things that fix the problem. For me it was reverting back to stock ruu. It was 4.03. 1.29..... something. But it also was fixed when I flashed latest paranoid android. Just a fee things to try....

Shut off after LG logo

D851 here, When ever i switched from cloudy 2.5 to blisspop 4.0 and after wiping everything i flashed a various of radios bootstacks and etc to make it boot after many failed attempts to boot ( it boots up but after 4 or so seconds after the lg logo the screen turns black and doesnt turn back on until after i pull out the battery) it worked after i flashed the rom WITHOUT a custom kernel so naturally i booted up just fine and thought maybe now i set up everything on my phone and tweaks i should go back and flash a custom kernel i used to use (777 r16) but then it gave me the problem i faced before the black screen after the lg logo no kernal would work. THEN another problem arised similar to the freezing on the black screen randomly during a usage thru my day the phones screen would be unresponsive animations but touch wouldnt work and i know its not my screen cause when i flash back to cloudy it works fine the freezing happens at least every 5 mins. someone halp?
i know this thread is kinds old...
but i have this same issue too... I found if I switch batteries the problem isn't as bad... but, then it becomes bad again. Its weird. Before I swapped batteries I couldn't even login with my google account, after a fresh flash. then after I swapped batteries (gf has same phone) I was able to get through to the end and setup the phone. But, then an hour later it started happening again....
OP, did you find a solution?

i actaully did i think one of the problems was maybe flashing over the same kernel? see what happened was after i gave up flashing the kernel i just flashed without it and to my surprise the build actually came with the kernel pre-installed...shocker and so i had no need to flash over the kernel that i wants because the maker of g3 tmo blisspop already had it in his build and it boots up fine( DISCLAIMER: i cant say this about other roms because the only one i actually tested and wanted was blisspop)

Okay.
Well, when I was flashing I never flashed a kernel.
Ill be getting a brand new Anker Battery in the mail today. Ill report my findings.
I ended up going to a stock based rom and the issue never happened. So I stuck with it. Ill have to do some testing later and ill let you know how the battery works.
It's not the battery
I downgraded my T-Mo G3 since I couldn't root it with LP on it. Went back to 4.4.2., rooted it, TWRP'd it, and installed the latest CM12 Nightly, Gapps, SU, etc.
As long as the sim card was OUT the installation was great on wifi only, As soon as I put it in it shut off right after, or during boot up. Take the sim out and it works. And yes, the only way to get back into recovery was pulling the battery and doing the key press to recovery. Mystified.
If I find out anything, I'll post it here.
I'd say do a complete return to stock, upgrade via LG Mobile Support tool all the way to 20G, see how it works stock for a while. Then root ( http://forum.xda-developers.com/lg-g3/general/guide-root-method-lg-devices-t3129197 using the first method) and see what happens.

Weird Power Issue with all custom RoMs

So I took out my age old xperia M(single sim) a couple of days ago and installed cm 12.1 on it. The only issue I'm facing with it is that if I keep the phone on standby for a while the phone completely and silently shuts itself off. When this happens it doesn't turn on with the power key as well so the only way to turn it on after this happens is by removing and re inserting the battery and then pressing the power button. (phone boots normally then)
This problem only appears when the phone is in standby. I could use it 2hrs straight and the phone would keep functioning normally as long as I don't keep it on standby for a long period.
I've tried tons of different cm12.1 roms and factory reset the phone multiple times but the problem is there with every single rom. Haven't tried any rom that isn't based on 12.1 yet.
Strange thing is that this standby dead thing doesn't happen when there is a music app that's playing some song while in standby. Even if the phone is on silent and media volume is 0. So the temporary fix is to keep playing some song and keep media volume at 0. I would be really happy if someone comes up with a permanent solution though. Thanks. Any help would be greatly appreciated
Was the problem present on the stock ROM?

I have the same problem with CM based roms, went back to stock and it doesn't have this issue, could it be something to do with ambient display/doze?

No, I don't think so. Which version did you come from? I would suggest flashing 15.4.A.1.9 first because most custom ROMs use it as base and doesn't offer full compatibility with older versions.

Nope. My sister had been using this phone on 4.3 since 1yr now. I decided to use it as a secondary media device when she got a new phone. When I first unlocked my bootloader after rooting the device went into bootloop. So had to restore it to stock 4.1 Indian (couldnt find 4.3 indian ftf) using flashtool (took 2 days and tons of researching to get the drivers working). Then I rooted it again and flashed twrp and cm 12.1. Have been facing this problem ever since.
It's driving me crazy now. Might go back to stock if it doesn't get fixed
Edit - also just checked the sim slot isn't working either. Tried multiple 12.1roms but it won't get detected. Didn't realise this before as I'm using this as a media device and don't need sim card working anyway.

Do what I said to @kurtbvb too, as it may just be base incompatibility. Flash everything except the TA partition (if present) and wipe /data and /cache.

So do I flash stock 4.3 using twrp or do I need to flash the ftf file using flashtool ?

Flashtool. Some files are required which custom recoveries can't flash.
Just flashed the above mentioned ftf file and then rooted the phone, installed twrp and then cm 12.1 based rom. Everything runs perfect now. No random shut downs and Sim card works as well.
Thanks you so so much

Camera error, can't connect to the camera

So after flashing MHC19J via Clean Core, I can no longer connect to use the camera. What's even weirder, is that I downgraded back to my previous ROM, and now the camera has the same issue. I have no idea how to fix this. I have uninstalled the camera app via system remover app and reinstalled it. Issue is still there. Tried clearing data and cache, still not working.
Any suggestions? I have never had this before.
I have the same problem, could you find any solution?
I have to same issue too... help?
Guys try to flash full stock rom using sdk and then write if problem still is
Sent from my Nexus 5X using XDA-Developers mobile app
I'm having yhe same problem, and it's acting strange, I wass on stock N when camera didn't started, rooted installed custom rom, and it didn't start neither.
Reverted to stock MM, and didn't start, upgraded to stock N again and worked just fine, after rooted and installed custom rom again it worked perfectly, and moments later didn't started, Rebooted two times and worked, later it didn't started again.
Tried to change vendor, rebooted in safe mode, nothing worked, any clue what might be the problem?
SOLVED: flashed the vendor again after installeg rom and camera started working,
Thanks!
Hi, after a while, the problem reappeared.
Again i've flashed the vendor.img and camera worked just fine for a while.
If i reboot to safe mode camera works fine but one time the camera didn't start even in safe mode.
So i can't find a proper path for this problem.
I've recorded 2 logcats, - at the first one camera worked fine
- the second one camera didn't start

Where did you buy? My phone was repaired by LG by warranty after the infamous bootloop issue and now camera has errors sometimes.

I'v bought one on second hand, from a bootlooped device. For. Me, it worked, i'm not 100% sure it will work for you but i'd try it if i were you. If it doesn't work you can sell it after.

Camera won't focus after downgrade to LP

Hey guys,
I got my G4 H815 delivered with MM pre-installed a few months ago. I decided to downgrade to LP to root the phone without unlocking the bootloader. Everything worked like a charm, except the Camera won't focus anymore at all (no matter what app), the manual focus does not work either. I already did multiple factory resets (removed root, tried a different LP version) and cleared the cache for the camera app.
So after nothing worked and I worried my camera got a hardware defect, I returned to Marshmallow, and yes, the focus works perfectly fine once again. So the hardware does work. After that I tried an older LP Update, but same result. So I flashed MM for the second time tonight, and ofc it works on MM...
However, I would prefer to have a rooted (but locked) phone. Is there anything you guys could think of that causes that behavior? As I said, I got my H815 with MM pre installed!
Thanks for your help!
Any ideas?
DO factory reset ! hard reset !

hi !
-the firmware update is to fix errors and improve the phone a bit. there are several videos on youtube that show the focus problem of g4. focus is slow. mine was with MM too so i don't have any personal experience on that problem.
-yes you can root without unlocking. unlocking the bootloader is something you are gonna do to install a custom bootloader or custom recovery.
Also search better this forum. there are custom roms you can install and keep your bootloader untouched
Sorry for bringing up such an old thread, but have you found any fixes? Im having the exact same problem right now.
Same here, I was forced to go back to MM as a result, but i miss having root so much
