Hi, i'm new here, but i searched everywhere.
My phone (g8s thinQ European version) is freezing and rebooting after connecting it to via chargeport. Wireless works fine.
My question: does anyone know, what the problem could be or has anyone a kind of service manual für disassembly and fixing the motherboard? I really don't want to buy a new one as long as this is not absolutely needed (a chip repair would be sufficient).
thanks in advance
Edit:
A replacement pcb-board with charge connector made no difference...this seems to be fine
Hi, i reached out to a specialist for phone repairs, i cannot repair it myself. he said, as log as he has no access to schematics or something like this, he is not able to repair it. my options: buy a new phone or find a working mainboard or get the documents to repair. so i choose the last option first

Hey guys, need help from the guys who do a lot of shopping around cell phones shops on the web. I need to replace the Microphone on a T989 and so far i have not been able to find a shop online to fix that issue. So if someone have seen this service please let me know. Since i think it needs to be replaced with an infrared soldering station.
Hello everyone
I m working for a mobile company (Wind telecomunications) in Greece and we recently recieved in the store a demo unit of S4. All the other devices we used to recieve were proper phones with proper functionality. It is the first demo unit we recieved (no imei on device) so I would like to know if there is any way to transform it into a normal device. I read some articles on internet about demo units. Some of them saying that flasing a rom solved the issue but some others say that demo units lacking the antenna. Probably mine is missing the anntena as well because I tried to put a sim card and there was no response from the phone. Moreover by calling 112 the phone says that couldnt deliver the call.
So... Propably is antena problem. I would like to know if it is possilble to order and antenna part from ebay (or other) and istall it to the device along with firmware installation or demo unit can be used only as a tablet without sim.
(Important! I am not stealing the device but I am about to use it after it gets off from the live demo wall.)
Thanks

i dont think you can buy just the antenna. you best bet would be to get a broken galaxy s4 from ebay and scrap it for the part you need.
and even then i dont know if you are able to transfer the antenna. Someone with more knowledge about hardware could clarify if its even possible
Hmm i would try flashing stock firmware and use a tool to repair the imei not going to mention the tool here ,...go to a cell phone shop say imei repair they might help u ...

The problem is not the imei repair but if the device can be used like that or not. If someone knows what exactly is the problem and how it can be repaired.
make me call

hi
i have the same problem, an s4 demo and i can tell you that you nedd an anttena and maybe an other motherboard.
i ve buy an antenna on ebay for 11$ and i will try to place it ....
After that i ll tell you if it s good or not
sorry but i m not english
i know that because i have already this probleme on a s3 demo and after buy an antenna il change the motherboard generally on a broken phone (price of the screen is so expensive that you can have one for not very expensive...)
Good luck ....
Hi XDA users.
My problem is just same as this thread's title.
A few months ago,
suddenly I had an idea which try to disassemble my Xperia Play.
So I did that and consequently one part of touch screen couldnt work normally.
So I decided to repair it and it has been repaired.
But another problem was happened...
First, the speakers didnt work.
At that time I flashed Gin2Kitkat.
Though I flashed any other ROM, they havent worked still now,
I think the reason of this problem isnt software but hardware,
The only solution seems to replacing this part.
Moreover it cant connect network.
In my country there are two carriers which I can connect with my Xperia Play.
But though I selected one my SIM card support, it couldnt get any network.
However SIM card itself isnt wrong.
Because it worked normally when I put it another device.
I want to repair it.
But I dont know what should I replace component.
It is main board?
Also I wonder whether there is a way I can buy it.
For reference if there is any item in eBay, I can purchase it.
Thanks.
Model H815, bought the device at launch. From UK.
So a couple weeks ago I was messing around with rooting and all that, managed to flash a bad file and ended up in a boot loop. Fixed it using LG Bridge, flashed all the right files and was running a rooted device fine.
Then maybe a week after that whilst just using the phone normally, it freezes, the speakers make a weird buzzing noise and then the phone turns off. Ever since it has been bootlooping. I tried fixing it using LG Bridge again, using the 'Update Error Recovery' option with the device in download mode, it says it was successful but the device still bootloops.
Not sure what to do? Will LG replace the board if it is a hardware fault even though the bootloader is unlocked? I may have also taken the phone apart with the intention of baking it, but never did. Would they be able to tell that I did that and then not repair it?
How much would a repair cost if for some reason it wasn't covered? What's the best way to get it repaired? I got it on contract from O2.
Also, if anyone knows where I can buy a motherboard that would be great, as I'd rather just repair it at home instead of sending it off to LG not knowing if they are going to charge me or not.
Thanks in advance.
It is caused by hardware fail, not by you.
Some people admitted that LG repaired their phone with unlocked bootloader, no luck for me, trying to argue with them.
They'll give you a number to SBE (Their 3rd party repair service), again few people admitted that they repaired their phones for freaking free. No luck for me as well here. They've said "It's unprofitable for them to repair it". I actually think they are retarded, thats a quote of first 2 sentences from their response to me: "hank you for your email. If your handset is still in warranty we would ask that you contact LG customer services for further advice, as we only carryout non warranty repairs on behalf of LG. If your handset is out of warranty by date unfortunately we may be unable to offer a viable repair solution." - WTF is that?
Lastly there is no official place where you can buy a mobo, asked LG about 2 weeks ago - no response...
