Many HW problems

Hi,
I've got these three problems with my HTC. I've tried different ROMS and RADIO but always the same problems :
Rear camera HS (unable to open stream) - Known problem in this forum. Seems to be the motherboard
Bluetooth - Can't activate anymore. One morning, I tried to activate it, ans it didn't work. Nothing change during night
FM Radio - Unable to activate radio. I don't know when this problems starts
=> My motherboard is HS ? HTC wants me to send them the phone. But I've no more any warranty. So how much will I have to pay for the repair ?
I think a lot of people have problems with the mother board. Isn't it a possibility that there is a real problem in Cruise ? So no problem with warranty. They have to change ...
Any suggestion will be appreciated ...
Thanks

how long have you had your device?

18 monthes

probably going to be hard to claim under warranty then

In France, we have the notion of "vice caché" (hidden problem). in fact, if too many people have the same problem with the HW, then there is a problem with the design of the phone. so the warranty can be applied even if one year has passed; so this is why I'm trying to know how mqny people have the same problem.

maybe you can try - but HTC are not good at accepting warranty (in my part of the world anyway). Good luck

Warranty issue...

Hi all,
I have the following issue, my Touch HD won't turn on anymore. I have tried a few tips and tricks that I found on the forum but non worked, so the only option I have now is to send my Touch HD to HTC for repair.
My Touch HD has a costum HardSPL, I can't flash it back to stock because the phone won't turn on anymore.
Will HTC check this if the mobo is the problem?
Or is there a way to flash to stock without turning on the phone?

I don't think there is a way of undoing the customization without powering on, or taking it apart and changing the mobo.
If its truely bricked though how would they know what was on it if they'll have to change the mobo before it powers on anyway?

Thanks for your reply.
Are the rom chips part of the mobo? in that case it might be my way out...
I just want to know how far HTC would go to check for "user-error".
Has anybody been in the situation?

Haven't been in that situation.
All i can speculate is that if the phone is dead because of some sort of defect or damage on the motherboard, then I don't think that HTC are going to catch you out on having a cooked rom, I don't think their RMA dept would take the time needed to run the flash on a new board, and you'd just be successful with the warranty if thats the caste.
If the phone is bad due to something other then the main board then chances are they may reject warranty and expect you to pay to have it fixed, again though, I dont know for sure, this is all just speculation.
oh and yes, the mainboard houses the cpu, ram, gps, wifi, internal flash (rom), even the card reader and sim reader, although there are technically two parts of the mainboard, the part with the flash is the part with the cpu and ram, so i daresay if theres no life in the phone at all (and you've tried another battery or direct off the charger and still get no power) then chances are its that board.
the power button however, is attached to the top flex PCB, so if here is where your problem lies, then your mainboard may not be at fault.

S4 i9506 both cameras not working (tried everything i could find)

Hello there to all.
I´m newly registered to the forum, although i´ve been using it to search, learn and use roms in my Samsung s3 for some time now.
I´ve bought recently a used S4 i9506. At the time i tested several key points of the device to check if it was all working, however (and don´t ask me why because i cant explain it), i completely forgot to test the cameras.
My problem is the following. Everytime i try to access the camera it says that camera failed or something like server connection failed. I´ve tried every single resolution i could find on the internet and so far all failed to solve it. The problem seems to be in both cameras, i think, because when i try the code *#0*# both Mega cam and front cam give error. Here´s what i tried so far:
- Soft Reset/Hard Reset/factory reset;
- Cleared cache both from boot and manually erasing cache from com.sec.android.gallery3d;
- Tried 3rd party camera apps from GooglePlay;
- Tried the RestartCamera.apk;
- Tried 3 different firmwares for i9506;
- Tried rooting it and then flashed several different roms;
- Switched the rear camera with a new i9506 rear camera module that i bought;
- I cant also test the cameras, because when i use the code *#34971539# they bring a menu on which i can´t use almost every option (see image);
http : / / rghost.net/6Zby4zXFD/image . png
Anyone have any other possible resolution?
I´m thinking on maybe buying a front camera module. Could that do the trick? Could the front facing camera not working properly make the rear camera fail as well?
Thank you for the attention to all who took the time to read.

So far 60 people read and nobody answered. ... is it because you don´t know what else i can do? I´ve been reading the problem may be from the motherboard. What can i do on the motherboard to make things right?
Thanks again

Be patient my friend someone will answer soon

Hi,
I've got the same problem with my s4mini. Both cameras aren't working and all the solutions you explained don't solve it.
I'm thinking about buying another S4mini with broken Display in order to change the motherboard. This might be the only possibility to solve this......

Hey there m8.
I know the feeling, right?!
The thing is that for a faulty i9506 model i could almost buy myself another motherboard and mount it, but i was hoping to find some other solution, maybe even some electronics expert opinion on what i could do in the motherboard to make it work again. There are some videos on youtube that teaches how to change some components on the motherboard to solve problems like dead smartphone or constant auto reboots. Also, finding a faulty i9506 model isn´t as easy as finding a regular S4. :crying:
Thx for sharing the problem and for the opinions,
and greetings from Portugal

Today i've changed the mainboard aaaaaaand -> cameras still not working
So i started to change the front cramera and the ear-brightness-sensor from the old s4 mini with the broken screen into my working one. And now both cameras are working again!:good:
I think the cause is most likely the brightness sensor which is combined with the ear speaker. This could explain why both cameras are not working.
I'm not completely sure due to i changed the front camera also. However changing the main camera did not do anything as mentioned above.
Maybe i should mention: A few weeks ago i've changed the earspeaker-brightness-unit because the speaker wasn't working anymore. Right after this both cameras stopped working.

Thank you for the update on your situation m8. That could be some relevant information there. Can anyone confirm if the sensor is the same for all s4 models? If so i could find more easily one from another s4 model and try it, for the sake of desperation.
cheers

[Q] HW related warranty and root

Hi, my rear camera become unstick, rattling and swimming in its frame. It is obviously bad luck HW issue, phone is without any signature of usage, but it has tripped Knox already. Do they check software side and deny free repair when issue is completly HW related and it has nothing to do with software- which is replaced back to stock and everything works fine? Anyone with personal experience with samsung service and support?

Hi M8,
My galaxy s7 edge was rooted just had some repairs done under warranty without any problem, hope this help.
Cheers

Broken GSensor

Hi there are any way to fix GSensor ?
Because thats the reason why screen rotation is not working in my case after bootloader unlock.
In calculator i write in ",1234+" a tap on gsensor test and the result is fail.
Thanks in advance

The accelerometer is built in to the logic board. Chances are slim of repairing it without a logic board swap/phone replacement. Contact ASUS for warranty repair if you're under warranty.
It could also be a custom ROM issue if you're using one.

That issue and couple other appears after unlocking bootloader (official app from asus) so I do not have warranty. I try on LineageOS and stock firmware but in both case GSensor is broken.

G sensor fail

You need to delete the file /persist/sensors/sns.reg using TWRP or a root-enabled file manager. I've had this problem a few times myself and deleting that file takes care of it.
