Hi guys,
I have a strange behavior and I hope you can help me
I recently dropped my Mi5 into the water. :crying: The display didn't work anymore, I found out, that the contact for the display was damaged on the mainboard and ordered a new one.
After installation, the display works again
The only problem: As soon as I connect the main camera unit, the device doesn't boot any longer, but lands in the boot loop. I also have a 2nd camera unit and here the same happens. That means the camera unit shouldn´t be the problem.
Did you have an idea, what could be the issue here and how I can solve it?
Like said before it is strange because without a connected camera unit everything boots without a problem into the system.
Thanks in advance for your awesome help
Just wanted to let you know, that this issue was a hardware defect of the new mainboard yesterday I got another one delivered and everything works without any problems \o/

Hi, I've had thus problem for quite some time now and I'm not really sure what the cause of it is. A while ago I changed the housing of my m7 to gold and since then I've had some problems. At first my charging port started malfunctioning and no longer worked when I plugged it into my laptop. I replaced it and not it works fine but then the vibrating motor stopped working. I replaced that too but it still doesn't work and now my camera and volume button doesn't work either. I thought that maybe if I replaced the daughter board that it would fix those issues so I bought a broken HTC one off eBay and switched the daughter boards. It fixed things for the most part but vibration still doesn't work and apparently the owner was messing around with the Sim card connector on the daughter board and somehow broke the clamp to hold the sim flex cable. So I have no mobile network and it's currently useless to me. Since vibration still doesn't work I can't help but think that maybe it is somewhat a motherboard issue. I'm thinking that maybe some of the connections aren't clean because of how many times I've opened up the phone and touched all over. I'm thinking of getting done isopropyl alcohol to clean it and see if it fixes the issue but first I was hoping that maybe someone could help me out and tell me if it really is a motherboard problem.
Bought a broken phone and used the internals to replace with mine and everything is great. Finally got a camera without people tint.
Hello all,
My Xperia was in a serious bootloop that I couldn't fix, not with pc companion not with flashtool flashing stock roms. So I gave up and sent it to the closest Sony Mobile certified repair store, it took them one month to tell me they couldn't fix it, they said they opened it, changed the battery and it still had the same problem so they also gave up and gave it to me, they did say the problem could be the motherboard. I'm now living in Brazil and getting a motherboard for the c6602 is impossible first of all because the phone was never commercialized here (and importing is impossible, it'd take 2.5 months and they'd charge me 200% of the part price, unfortunately that's how Brazil works ). Something interesting that happened is that when I got my phone back they had solved the bootloop issue but they created another issue, the phone starts makes all the sounds the screen turns on BUT all you can see in the screen is the black color, so the backlight is on but nothing shows up.
Could I be able to fix this via software? or the only option is changing the motherboard (or maybe fixing something on it)?
If any of you knows how to fix this I'd appreciate an answer.

How do you know it isn't a display problem?

Because I sent it to sony and they said the problem was the motherboard and the problems the phone's been giving are pretty random, for example at the beginning the problem was that it had random reboot each one with more frequency, it when from that to just work with the ac adapter connected, it went from that to a bootloop of just showing the sony logo and restarting, after I got it from sony the problem is that it boots app (without needing to be connected) it makes all the sounds like it was working perfectly but the screen is ON but black. So because all this I'm convinced it's the motherboard.
I see changing the battery didn't fix your problem.
I think it's so sad that this phone with just more than a year of life are getting this serious problems and sony isn't doing **** to help us. They keps my phone 1 month just to tell me that it couldn't get fixed, they said they changed the battery and all but still the same problem. I've reached a point when I just don't trust sony anymore, I'm getting a galaxy s4 on monday but still I wanna fix this crappy-phone.
Well, in my case it happened out of nowhere, I wasn't doing anything special with the phone..., I'm thinking maybe restoring the TA partition would fix something? I don't know... I found the motherboard for 80 euros in aliexpress
Hi guys,
I bought an Erisin android 7.1 car head unit 2 months ago, except the Bluetooth connection issue, it worked good. Today I got the boot loop problem, and searched by google, but still cannot goto recovery mode. My unit only has a rest hole in front and no physical button.
Anyone could help me to fix it?
Thanks so much
Hello xda community,
I contact you because my mum's phone fall and screen broke.
She took it to a phone repair shop that changed it, but she said it was still not working.
I was away, it was few month ago but now I came back and try the Z1 and touch and screen and everything was working fine when I tried. But after like 10 min no touch.
I found the way to reboot it, and when I reboot most of the time touchscreen work again, but go away fast.
I searched and found some thread talking about software issues for touchscreen, so I tried updating to lineage, but it's doing the same, so I suspect HW failure.
This phone still seems nice to me, the battery seems to still be ok, the screen quality is good, the lineage 16 is fine so... if I can revive it, I'd be happy to do it.
Any idea what can be wrong ? Is there any component failure that could lead to that ?
Thanks guys.
Hi all, I hope someone can help.
I recently encountered a Bluetooth issue, where the signal strength was very weak when using multiple pairs of headphones. I downloaded a BT signal strength app and using this, I found the strength hovered around 30-40%. Having had my screen replaced previously by a local repair shop, I suspected there was a loose antenna, so I opened the phone to find damage to the motherboard, whereby a small piece of the board was completely missing.
I then purchased a used motherboard from eBay which I then fitted. However on powering up the phone, all I got was the Huawei logo on black start up screen then it turned off. With charger connected it would continuosly bootloop. I then done factory reset and restarted the phone and after a few failed boot ups,it eventually powered up. It was locked with the screen lock from previous owner, which they were happy enough to supply. With the phone unlocked I then set about setting the phone up using my own Google account and all seemed fine. Every aspect of the software/hardware appeared to working perfectly.
I then updated to emui12 which appeared to download and install, however the phone went back into the previous state,whereby it turns off after the Huawei logo appears.
I have no file available in eRecovery. If I put my old damaged motherboard back in the phone boots up first time. I would at this point have given up and reverted back to my old motherboard, however when taking it out,the upper microphone has broken clean off the board.
Any advice out there?
Thanks in advance
Update, which may help anyone in the same position.
It appears the motherboard is paired to the battery and the boot loop issue was resolved when I used the battery from the donor phone I took the motherboard from. I assume buying a new battery would have been another solution had I no access to the battery which was paired to the motherboard I used.
