Hey guys,
If I am not in the proper place please help me where should ask my question!
My Isudar headunit (PX30) worked just a few minutes and after I got this result:
https://drive.google.com/file/d/1kJMHTu1fCbvtsEP6UIqnwG_VFAF5ss1l/view
It worked and suddenly said erasing sd card, after it turned itself off and till that time it won't turn on. The sd card contained the map and now it's empty. Can you please tell me what is the problem? The mother board is damaged or it's something else and I can fix this problem myself? I am worried to fix it myself because the headunit won't turn on.
Please help me!

First I want to say hello to everybody because this is my first thread.
I found a lot of solutions for my problems on this forum but I can not find solution for brand new problem that appeared yesterday. The thing is that my phone fall out from my pocket and now I do not have any picture and light anymore. I can turn on phone, synchronize with my laptop but no flashing light on buttons and no picture. The LCD seems OK (no scratch or visible sign that is broken).
Does anybody know what is wrong or what can I check? Phone has no warranty anymore.
try and get the help from general options.
if you cant get this fixed.. please let me know..
i am badly in need of dead Touch diamonds..
we are working on a college project....
please be kind
I managed to repair it. I opened it, put all together and it works now. I think that one (or both) connectors on the back side of main board lost connection when the phone fall on the floor. So lucky me, I have a working phone.
Sorry asnaveenkumar, now it works.
Greetings. The other day I was at the beach and this wild wave appeared and got my phone wet. The phone turned itself off and I removed the batt. I re-inserted it not knowing the phone turnred itself on automatically and it turned on but i quickly took the batt off again. Thing is, it doesnt turn on anymore. So I was wondering if theres a way to remove the internal SD card from the motherboard and somehow addapt it to a new mother board. I know it might sound hard but I NEED to save the info on that phone. It's basically my computer and I'll do anything to save that info. Thanks!
Well if you have good soldering skills and know what to look for you could probably swap them out.
So, if it is possible to take the chip away from the board and solder it to another working one, which one would it be? My phone was giving signs that it might work but it doesn't respond anymore. Anybody heard about this procedure before?
HI,
My HD7 keeps resetting itself at random times and its driving me insane. I have tried different apps to see if its that and no joy, new case to stop the chance of overheating its happened about 20 times in the last 4 months. My question is would replacing the motherboard help and if so where would I learn how to do this? I have changed the screen already so I would be willing to take it apart.
Thanks
It's absolutely a possibility that it could be due to a faulty hardware issue. The problem is that there are many reasons that can cause the device to randomly reboot.
Anything from -
Software - apps/XAP's, tweaks, registry changes, WiFi, OS version and radio version
Hardware - Faulty motherboard, SD card, worn parts and broken/damaged soldering joints.
Was the problem with the device rebooting present before or after you changed the screen? If the problem wasn't present until after you changed the screen then it's possible that there is a bad connection of some sort in the device.
Also what OS version is the device on and are you running a custom rom on it?
The actually disassembly shouldn't be much different from when you replaced the screen other than you have to separate the motherboard.
If you've exhausted all other possibilities and are pretty sure it's the motherboard and want to change it take a look a this thread and there is another external link in the thread too -

Here's a video that will give you an idea on the disassembly -

Ok thanks, so I had the phone from new, unlocked but using the 3 network. It started before I had even dropped the screen and put a custom rom in it, I was in a very hot country when it started so it might be slight heat damage. I have looked at the links and have now added them to my favourites. Although there is no direct link to a complete ribbon breakdown I am sure I can do it. Thank you for your help and once I have tried all aspects I will report back thanks.
Like me
I used the phone without the SIM card, no reboots or locks and reboots.
I'm using SIMs from a carriers using 850MHZ and 900MHZ all gave me reboots and locks, before the "solution" I used a 1900MHZ SIM with no problems (??? weird!!!)
Since the solution, I use my SIM without problem,
What I did:
1- Take the SD card and format it with sector check (long format) to see if there's a problem there, also give me manufacturer, capacity and class, if the card has it. Mine is a Sandisk 16GB Class 4
2- Raise a little the antenna connectors (2 copper fins near the sd card), BEWARE!!! they are FRAGILE!! if you break them (like me), you'll have to get some copper fins and use soldering iron (like me).
Believe me, I'm using my HD7 with no problem since then...
any question, here I am...
I have the sam reset problem but in one way. Yust if i use a Data connection to go on web. After random time, my HD7 start to restart itself. No warming or something else (mean overheat) of a phone.
What it could be? I am desperated
P.S. Problem starts when i am bricked my phone and went to "service" to do a JTAG flashing of it.
At first time after JTAG my phone warming up at a bottom of a phone (where an sd card settled and antena) ans start to reboot after Data connection enabled. After my complain to service they opened them again and told me there are all clean inside and after that my HD7 not wrming up but stil random reset after Data connection on web (HSPA+).
Any advice please or to throw my HD7 in garbage .
thx

Hello i have my old Xperia X8 laying around for a couple of months now and since i got my Xperia SP i did not give it the proper attention!!!
I love my X8 but it has some problems !!!!
1) It wont scan for wifi networks it says "Unable to scan for networks"
2) It wont read the inserted sd card.( on the statusbar it says "Removed SD card"
Although i flashed the original sw from SUS about 2 times the issues are still there.
So i came to the conclusion that the problems are related to hardware and specifically to the wifi module and the and card slot.
Having a small amount of experience with electronics i decided to disassemble the phone.
I inspected the wifi module , antenna and SD card slot as well to see if they had a visible issue.
Everything looked normal.
So i assembled the phone booted the thing up and i flashed from SUS the original firmware again.
As i am writing this the phone boots up.
Ill post the results later.
Also i could not find pcb replacement on ebay for the phone.Can anyone help me find one in case its a hw problem please.
Edit: Nothing changed im thinking of reflowing the pcb but im not sure about the zif connectors and the camera itself.
Opened the phone again checked everything no apparent damage.I haven o way to check deeper (measure and stuff i dont have a multimeter now nor an oscilloscope).

I had a very similar problem after replacing the screen, and it seemed that for me it was a poorly connecting GPS antenna. I pulled the antenna out and wiped the terminals and put it back in, and it helped. (It is having problems again, but I'm still working out why this time).
Similar issue was discussed in this post.
