Sometimes bricked phone? Strange problem

Hey guys (and girls),
I've got a strange problem with my phone.
Almost every time I have to shut it down it won't turn on again.
I can try everything like going in recovery or download mode, just nothing happens.
I installed JDC optimized cm 12.1 on the phone but the problem appeared after a failed factory reset in stock rom without anything flashed.
It helps when I remove the battery for a longer time, like an hour or so.
I installed a new bootloader and modem, I flashed a pit file but nothing helped. Flashing works without problem, once it turns on.
Generally the phone runs smooth and without any bugs or errors.
Could it be an hardware failure or is it a software thing?
Thanks in advance for any help! If you need more informations just ask. It's a i9505 by the way

It appears to be a software problem. If it is a hardware problem you would get the problem regardless of the rom that you flahsed.
Install the stock rom via odin and wait and see for two weeks whether the problem comes back or not. If the problem comes back then you might have a hardware problem.

I have the same problem. In another forum someone told me to be something relative to the power button but I've not tested that at the moment

I have actually no problems once the phone startet, everything works fine.
It has had the problem first with stock rom, then i flashed JDC optimized Cyanogen and it was still present.
Then i thought it could be some problem with the Memory and i flashed a PIT, but that didn't change a thing.
Right now i'm without phone since 15 o'clock, its 00.15 now. That really ****s me up!

[CM13.0 SNAPSHOT] issue with bluetooth

Hello,
After many researches on google I can't find how to solve my issue with the buetooth on my samsung galaxy s4. I have installed the last CM 13.0 snapshot rom (13.0-20160820-SNAPSHOT-ZNH5YAO0J3-jfltexx). To proceed I started with a GS4 with the following ROM I9505XXUHOH2_I9505OXXHOI1_XEF downloaded on sammobile. I did a full wipe to install a new ROM and then I installed the CM ROM. The bluetooth was ok at the beginning (around 3 days after) and now the BT is OK. When I restart my phone it turns ON but after severals hours the bluetooth crashes (without any warning). If I try to put it ON again it turns OFF automatically after few seconds. The only solution is to restart the phone to recover it.
I tried the bluetooth during one day without any issue when the GPS is OFF maybe this can help
For information I have no issue with the samsung ROM.
You are my last chance
Thanks in advance for your help and sorry for my English

Try a different ROM or a different snapshot.

Another idea?

Random reboots

Hello, everyone!
Last week I received a brand new Xiaomi Redmi 3S. Everything seemed fine until I noticed that the phone tends to reboot from time to time. Sometimes, it can't work for a couple of minutes before rebooting and sometimes I can spend hours playing with it before the error happens.
I tried updating to the latest official stable MIUI and the problem persists. I switched to the developer version, to no avail.
Then, I decided to unlock the bootloader and install a custom ROM (from Xiaomi.EU) and it didn't solve the issue.
Reading through some threads in the en.miui forums I found some posts by a guy who claimed that the problem could be solved by using KernelAdiutor... But his method didn't work.
I made a video, as the vendor requested. There, you can see the problem: It rebooted my phone twice in less than 5 minutes.
I think that this problem isn't related to the battery, as the reboots have happened even while the phone is connected, and just before each reboot the phone freezes for a moment, like if a program crashed.
Any ideas on how to solve this issue? Thanks in advance.

No expert here, but seems could be hardware error. Next time if you happen to have such thing, don't unlock the bootloader. But maybe you can relock it (if thats needed) and install stock and send it back to them. The device seems to have a defect.

same issue for ME also ! every day crying with redmi 3s ! F**k

No sound, clicking noises coming from the speaker

I have this issue with my Mi A1 where all of the sudden the audio stopped working (both from the speaker and earphones), and I get these popping or clicking noises from the speaker when it tries to play audio.
I did a factory reset, even replaced the ROM without success.
Any ideas?

I have the same...

It happened also to me on AEX 6.3 ROM, but I've downgraded to 6.2 and it sorted the issue.

A lot of stuff has happened since this post.
I couldn't get it out of a bootloop no matter what ROM I flashed (even stock using their tool).
I tried so many times that eventually I managed to get it to the welcome screen, but after a few seconds it reboots again.
Since it was still in warranty I sent it to be repaired, waiting for an answer.

Flash the latest firmware. Will most likely solve it: https://forum.xda-developers.com/mi-a1/themes/twrp-baseband-modem-april-stock-rom-t3777901
Edit: I realize that this is a somewhat older topic, but I ran into this problem recently and thought I would post the solution for anyone looking for an answer.

Redmi k20 gets stuck while trying to play sound

Since Friday my device is restarting automatically with error DEVICE CLOSED UNEXPECTEDLY
I tried hard reset went to service centre they did an software upgrade and then a downgrade to 12.0.3 from 12.0.5 but nothing worked
And now when i try to play any sound whether through YouTube , Music etc it is just crashing
Even the Sound settings are not opening and i couldn't connect to calls either and volume keys are also not working

Seems like hardware problem

But other things are working

Are you sure they did upgrade and downgrade?
Was it full wipe?
It recommend to flash custom ROM and see if sth cbange

Yes they did downgrade from 12.0.5 to 12.0.3
And I had full wiped from recovery 2-3 times
And yesterday I noticed one more thing my front pop-up camera was working fine but when I enabled sound effect for it
It just freezes

Ok, so that's officially India MIUI issue
try this
This is ultra battery saving option related and they're working on an update

i have already tried all these but nothing works and how my device is stuck in fastboot mode while trying to flash stock rom through mi flash tool

You mentioned earlier that phone is boiting, but it restarts often.
What error in miflash?

Yes it was booting then only when I tried to flash miui11 through mi flash tool it got stuck in fastboot mode
Mi flash was giving crclist error everytime
Anyways I have successfully flashed miui 11 through twrp but the above problems are still there

I had exactly the same issue with this device.
Then tried 5/6 custom roms of android 11.
Nothing worked, every os had it's own issue.
Then lastly I've installed PIXEL EXPERIENCE 10 PLUS rom and the phone started to work fluid.

I have a same problem. Whenever accessing sound, if freezes and restarts! Went to Mi center. They said they have to replace the motherboard . Actually it's one of the IC that's malfunctioning... Here's a video -

Let e know If there's any ROM that gets around this issue

Did you manage to solve your problem? I have the same issue and dont know what to do

Nope the audio issues cannot be fixed with any software. I think it's caused due to some IC failure.
You would have to change the motherboard to fix the issue or you have to be a professional electronics engineer who knows and have the equipment for micro soldering.

The same issue was encountered with me also. I am in great distress right now. Tried more than 30+ ROMs (including recover, fast boot, custom, and stock), but nothing helps.
IF you find anything please update here.. THat’ll be a great help indeed!!
