Urgent help needed, hardware problem??

I've got a lot of problems when my sim card is inserted in the wizard.
Sometimes I can boot the device and it's working OK for a couple of houres and then suddenly it's hanging or crashing.
The screen starts to get white and then stays white.
Then it's almost impossible to boot. I made a video to let you guys see what is happening.
There is WM6 on it right now, but it doesn't matter which rom I use.
Also with the original rom it's crashing. I've send it back to Q-TEK and the fixed it (they say)
but it's still crashing. The only problem is that the phone is out of warranty now, so I can't send it back anymore.
Can you guys help me out? I can't use the device right now because it's crashing all the time.

If you are having problems with the full original ROM package (e.g IPL/SPL and OS), then it seems like a hardware problem. As for the warranty, you may want to check with 'them', some products have a 'renew' warranty on the latest fix. E.g., if your phone is fixed today, it will have a new warranty (3 months or 1 year) staring tomorrow.

Unfortunately I had some water damage after they tried to fix it. (3 months later it got into the water)
The device is working as before and don't have any problems because of the water, but I've got a big red paper under the sim card.
So no warranty anymore
Do you think it's the gsm module?
Can I buy that "somewhere" to replace that part?

OKay, found a site where I can buy wizard parts.
Do you think I need to replace one of the boards?
And which one do you think?
There is a mainboard and one board that's smaller (with ribbons on it)

It's obvious it's something to do with the sim card. Try cleaning the contacts on both the phone and the card and if you can try another SIM card.
Failing that, I would suggest carefully stripping it down and sell the individual parts.
Use the money you get to buy another Wizard or another phone of your choice.
Just a thought. There are alot of people who would buy the components to replace broken plastics, screens, speakers...... etc

The sim card is OK. I tried many sim cards.
All the same problem. It's just something in my wizard
I can buy a new mainbord, but I don't know which one I must buy. There are 2 of them..

Help me get an antique xda going

Hello, I will start by saying despite my aged condition i have only recently (in the last week) been seduced to the ownership of any sort of mobile phone. I have one that works fine. But in my investigations a friend offered and gave me a XDA exec (O2) mainly to stop me moaning about the silly way text messages are entered with out a Qwerty keyboard. Unfortunately the phone seem to be dead. Or at least in a coma (as it has some life signs).
The symptoms are, White screen, not much else, odd times my eight year old got the keyboard lights on and thats about it, plain white screen. I have investigated the net for answers and tried. Reset (power, back light and reset), taking out battery and replacing, taking out the battery over night, i investigated 02's web site which i found of very little help, the user manual there etc presupposes some sort of information on the screen ! I seized on the idea that a Rom Upgrade might help but all links to that i have found are dead.
I installed Activcync to my PC and the phone syncs up allowing me to see that there is indeed things on it the windows files etc. Which gave me hope that it isn't totally dead.
So any suggestions? can i do anything with this impressive looking paperweight?

Hi,
From your description I would say you have a hardware fault regarding your screen.
Either the cable is broken, not correctly connected or the LCD itself has a defect.
What let's me conclude that is:
- you say you will get a white screen: this means the backlight is working
- you say ActiveSync will recognize the phone and you can browse its contents: this means that the device is working (except for the screen) and that it is not like stuck in the bootloader, or so
- you say your daughter managed to get the keyboard lights on: this means they are working... this, by the way, only happens when the device is in the dark and thats probably why you did not manage to do it yourself
From now, your options are:
- sell the device as broken and get up to 100 Euro on eBay for it
- buy a working Universal at eBay, at prices starting at 140 Euro (better condition will cost more)
or
- get the PDF that explains how to disassemble the device
- check if all cables are properly connected
- check if there is something you can (and know howto) repair
and eventualy
- buy a new display, which will cost 100 Euro or more
So to tell the truth, the easiest option is to actually sell the phone as broken and get a second hand one, which is not broken...
Or get a second hand one (not broken) and keep yours for spare parts.
Cheers,
vma

ah thank you for the step by step reasoning there, i have to agree...
I don't want to sell it, it was given to me and if i cant get it going i'd rather pass it on in the same way.
I will look for the pdf and see if i can confidently have a look inside... many thanks.

A small investigation inside reveals no obviously loose cabled etc.. Oh well!
again many thanks.

I've passed it on to someone who is more electronically knowledgeable than me, i hope he can get it going and use it...

[Q] Nexus 4 with broken (fullly black) screen and no USB Debugging

Hello xda-developers forum,
I realize this has been asked before, and I've read through many threads here and elsewhere, but I'm not getting a definitive solution that works for this particular situation.
Here are the details:
Phone Model/Make: Google Nexus 4
Carrier: Wind Mobile (Canada)
Screen is cracked/broken, completely black.
USB debugging is not enabled.
Completely stock ROM, have not made any customizations to the phone.
I have adb set up on my laptop, but don't know how to proceed in terms of loading into bootloader (?) and flashing, pulling data, etc.
Mostly only need to retrieve photos and videos. Already synced with Google for contacts (but not photos, unfortunately).
If you need more information, please let me know.
Is there any way I could retrieve the photos or are the precious memories lost forever?
Thanks in advance!

I dont know what cause you that problem.
but i suggest you to install driver on the computer and with tool box install stock rom in your phone.

Installing stock ROM would wipe his device, if he were able to, which he obviously can't.

A new screen should work, as long as that's the only thing that's damaged. It's up to you whether it's worth the $45 for a new screen assembly or $60 for the entire front unit (less frustration and possibility of screwing up than just the screen assembly) to save the photos on your phone. Those are USD amounts - I don't know how that translates into Canadian or if shipping will be extra. Swapping screen assemblies on the Nexus 4 is actually fairly easy - especially if you buy the assembly already installed with the bezel. I've done it myself probably 20+ times trying to get mine to work (I eventually did). There's plenty of teardown guides and videos on youtube on how to do it. Get yourself a new battery while you're at it, for $20. Maybe you've already replaced your phone, but either way you can get practically a new phone for $45-80 depending on what you want to replace, or a cheap back-up (always good to have) for whatever you've replaced it with. Plus all your precious memories back.

You cannot unlock the bootloader without losing everything so your best option to restore important data is to replace the screen. The battery is glued pretty hard to a breakable piece so watch one of the YouTube videos and decide what all you want to replace. Ifixit had a good video that I used when I had to replace the logic board in mine.

Broken phone: Jiayu s3 broken screen, touch working no display

Hello xda developers users, today i found out that my dad broke his phone. At first i knew that local shops would'nt be able to help since its not something that has been bought by one. The bigger problem is that, the usb debugging wasnt enabled so i cannot pull out all the pictures. I looked up everywhere for a solution and there was no program that supports this type of phone. I have also tried plugging it into the pc but it showed that:" please insert driver g". tried everything i could so if someone could please find me something to take out the important pictures of the phone i would really appriciate it. ( he doesnt have any type of backup since he barely knows how to use a phone)
Have a nice day!

unfortunately when there is no display you can't do much... you can't enter recovery or put your phone in MTP mode to copy files from internal memory. that's why PC can't install driver. By default with USB is only for charging.
I got Redmi 5 Plus using Tapatalk

If display is working but no touch, you can connect a USB mouse with a OTG cable.
No picture at all, try to get another S3 and swap the mainboard or buy a new display, there is new stock at some sellers at AliExpress for reasonable price.

There are YouTube videos about changing the display. You can buy a whole new display (with tools) from Aliexpress. I bought such a set for about USD 55 and replaced a broken display. It succeeded otherwise well, but the front camera does not work any more - maybe the tiny connector is open... The operation takes some time and patience, watch the video before byuing a new display!

Recovering data from an encrypted LG V20 with a broken screen

I've got an LG V20 (H990ds) with a damaged screen and/or main board. I want to recover data from it. The phone is encrypted. I know the PIN, but can't enter it.
I think the phone got some water in it. The screen comes up black, though I can see a bit of backlight, and get sounds that suggest it's functioning normally except for the screen. It has come to life further since it was damaged, with the display working, but not the touch-screen functionality, and on one occasion with full functionality. Unfortunately I didn't back up then, and it now won't come on at all.
I've bought another of the same model phone. Can I take the phones apart and use the new screen to access the data on the old phone? Is there a guide somewhere I can use for this?
Where is the internal SD card? Is it in fact a detachable item, or is it built into the main board? If it's the main board on the old phone which is damaged, what are my options?
