I had a problem with my head unit and wound up purchasing a new one. Between order and delivery dates, my original unit started working again and would like to sell it. Is there a way to purge it of all personal data without performing a complete reset?
On a side note; who wants a nine-month-old head unit?
Can you put some photos and a complete description of your HU (MCU version, etc.), please?
I have the dual-core 800x480 version of this;

Mine is a Joying unit.
It has worked fine for the past several months, but developed an issue where the screen would flash, pixels would be in the wrong spots, and then go dark. Despite all that, the touch screen part of it worked fine (as long as I knew where to press, I could get it to work). After much discussion with Pumpkin, I removed and installed the ribbons to the screen. This did not fix the problem right away, but the unit is working fine now thanks to the FM Principle. My skills have reached their very limited limit and I fear the problem will manifest again.
I personally think there is an issue with a connector to a ribbon or else the screen itself has problems and that someone with a little bit of knowledge can make this 100% again. If I hadn't jumped on a holiday sale, I would keep it and be happy. But I did jump on that sale and would rather recoup some of my money than install the old unit in another vehicle or give it to my cousin to enhance his electronics education.

Hmm. Wish I saw that before I did a full reboot.
Thank you. I will keep it in mind for next time.

Hello, I am facing a very frustrating evening with my beloved Epic 4G as the front half of the phone appears to not be getting power (i.e. no screen power/no LED when charging/nothing whatsoever). To top it off I have no backup, and I'm straight broke as can be. So I took the phone apart, and what happened is that the connection that goes between the back half of the phone and the front has simply snapped into two pieces. I've attached pics of what is broken and you can see my baby all disassembled as well (dang man this is not a very good situation). Bottom line is that my only option is to hopefully find this piece as the phone boots up fine, the keyboard lights up, and the phone even rings when called, etc... just no screen activity at all. I even Odin'd to stock w/o the screen working as the phone is perfectly fine except for the screen not turning on. I have confirmed in this video (Go to 4:05 mark in video to see the piece in 1 piece) that the piece I've shown as Broken is in fact supposed to be one piece, and given that everything else appears normal/functional I have no reason to believe that I have anything else wrong. Dang I love this phone and I need it to be working, so please someone tell me that they've got the hook up/connections to get this piece at a good price.

I take it you don't have sprints TEP? If you do have TEP I know some repair centers would fix it within a hour if they have the parts on hand.

i sympathize on your situation, also allow me to give you some advice, always make sure you have a soft cloth under the phone and you are not sitting on carpet. you can short out the phone. (static micro shocks)
Hey all; I got a Nexus 7 this past December and everything was working great until yesterday.
I took it out of my school bag and when I pressed the wake button this happened:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Now whenever I wake up my Nexus the same thing happens. Sometimes it goes back to normal after a few seconds, but it continually freezes or has random slow downs.
I reset the device and erased all my data and whatnot, but still the same has happened.
Any suggestions?
What ROM are you running, stock or custom? Try reflashing a ROM (let us know if you aren't familiar with that) in case something's corrupted. Hopefully it isn't something with hardware.
This should be a hardware failure.Take it to the service.
@Pandae: Everything was stock. @GeoVali99: Correct-o, sir!
Ended up being a hardware issue so I'm getting it repaired.
I appreciate the words though!
Hi!
I've got the same problem.
Can someone tell me how to fix that Problem by my self?
I have no guaranty left...
Thanks!

Not a big deal. The LCD is fine. What happened in my case when I got exactly the same screen is that the amber ribbon (LCD to motherboard) seated wrong, and I bent a pin on the motherboard connector out of shape. You open the back cover and reseat it, but make sure you do not damage the pins. In other words do it very gently, do not force anything, and monitor it all with the help of a magnifying glass.
The charge port on my phone went bad and needed to be replaced. The replacement went smoothly but now it I have no bluetooth or wifi antenna. I get maybe 1 bar indicated if I am a few feet from a wifi hub and bluetooth isn't working at all. I thought it might be something to do with the new charge board so I replaced it again with the same results. If anything it might be even worse now. Any tips on what I should be looking for that is wrong?
Sounds like you broke one thing fixing another . If it's physical damage you need to go backwards and check all your steps and see what happened.
If software issue try reflashing modem.
Pp.
I found the problem and it, which is a simple one, The fix though I think is going to be difficult. A very, very small capacitor is missing from the board. I must have hit it during the charge board change. If I knew the value of the cap I could probably solder a new one on. I have no idea how to find that out though. Here is a picture of the missing part.

A lot of internet digging has turned up the spec on the missing cap-
Samsung part #2203-006665
0.0022NF,0.25PF,25V,C0G,0603, C-CER,CHIP
That particular number is out of stock everywhere but I was able to find an equivalent from DigiKey.com
Samsung #CL03C2R2BA3GNNC
Digi-Key #1276-1403-1-ND
I bought 10pcs @ 2 cents a piece.
Good luck with the soldering,
In case that doesn't work for you maybe this will work for you.
Pp. Lol
Soldered in the microscopic capacitor yesterday and phone is back to 100%!
Hi all, yesterday I replaced the digitizer on my son's s4 mini, first time I've attempted this, but seemed a fairly straightforward process, took the phone apart without issue, placed all the relevant parts into the new digitizer and reconnected everything, put the battery in and powered up the phone, and the screen seems corrupted, I've taken a picture to show the issue.
Any help that anyone can give will be greatly appreciated.

I wonder if a flex cable got partially torn in the process? I have never done such fine work, especially not to an S4 Mini, so I'm not aware of all the pitfalls.
Best of luck though!
Nothing that I could see, I've checked all connections and cables 3 times, and they all seem fine, I have sent the ebay seller that I brought it from as I fear the screen is faulty, but as yet no reply, thanks for your message ?
Hello, i wiped my phone(system,data,cache) and flashed aquarios rom, but after rebooting my screen was not working, system booted up and i can hear volume and vibrations. But i cant locate the problem... could it be in hardware? I tried to disassembly phone and clean contacts and make sure everything is good connected. Also tried to wipe everything and flash stock 7.1.1, then 6.0.1, and still the same problem. Anyone got any idea? Should i replace the screen? Thank you

Maybe your GPU died? it's part of the CPU chip, and we know that unfortunately this CPU (SD808) is prone to fail on this device, due to heating-cooling cycles that creates cracks in the CPU chip substratum (looks like LG miscalculated the coefficient of expansion). I am saying it based on that you were flashing your device (it produces lot of heat and CPU use), and then, after a reboot the issue showed up.
But it can be faulty screen, this would be very weird (since i am assuming that you did not drop it during the flashing process or something similar) but not impossible.
You cleaned the connectors on the motherboard with isopropilic alcohol? i had a similar issue on my N4, and it was the solution.
Anyway if i were you, probably i would get some chinese and cheap screen replacement, at least to discard the faulty screen theory.
Thank you very much, i wouldnt think it could be gpu problem, but it looks like it is. I am going to give a try replacement screen. Taking into account my usage of phone, it would explain the dead gpu.
