Hi all,
The gf's LG G3 took a fritz a few days ago. Been working absolutely fine from new (18 months), but now it comes up with "Hardware key control mode" on power up.
I have tried the 3 finger power up to turn off this mode, but it just comes straight back on once booted.
I have also replaced the screen and digitizer - but still get the same error. So this suggests a fault on the mobo itself...
Question: From adb commands alone (since I can do nothing really on the phone!) if I get a replacement LG G3 (or motherboard at least) is there a way to copy *absolutely everything* from the faulty one, and restore onto the replacement one?
I mean everything - settings, apps, backgrounds, ringtones, sent/received texts, photos (ones on the phone obviously, not the SD card) so basically once I put her SIM and SD card in, the gf would think it's still the same device? I bought it her as a present and she would be devastated to think it's totally goosed and needs to be changed - not to mention the heartbreak if she lost any photos
Thx in advance

i dropped my phone and since then the screen refuses to turn on. it seems like everything is working fine except the screen. calls are coming through and im able to answer the call as long as i swipe at the right spot. is this something that can be fixed instead of swapping out the phone? if this cant be fixed and i have to get a new unit, can the sprint technicians be able to somehow transfer everything over to the new phone? btw, my phone is rooted with cwm installed and nandroid backed up to internal storage since i have no sd card installed.
If you can connect via USB you can grab the data from internal storage possibly, but it sounds like, at best, your display has a hardware issue ( strange that the touch works but the display doesn't)
But I see a trip to the phone store in your future.
If you can, I'd recommend booting to the boot loader (pwr-voldown) and using Odin to flash a stock from first so you can at least have the chance of getting a warranty replacement. ("Not sure what happennes, the screen just doesn't work anymore...")
Good luck.

Sounds like something with the connection between the LCD and the motherboard. You could get lucky and only have to reconnect the LCD's ribbon connection, however, if the LCD is cracked in any way, it would have to be a replacement, that is, if they allow replacements on cracked LCDs. Every ASC location is different. The only way to transfer anything would be to connect it to a PC, like he said in the above post, and hope it connects as USB storage by default. Copy everything to the desktop and then drag-and-drop onto the new phone's storage. But dude, get an SD card. It really makes EVERYTHING so much easier when transferring to a new phone.
The LED back light system and the touchscreen are independent of each other. Sounds to me like the connection to the back lights and the power got disconnected.

that is exactly what it seems like. can i take it into a sprint store and have it repaired or do i need to send it off?
As long as there is no physical damage then I would say its repairable. If you have ever seen a smartphone dissembled you should go check it out on you tube. Alot of the connectors are very small and easily popped out.
Hello there
Im hoping that someone here can help me since im ready to seel the pho for spare parts... i've tried it all.
Heres the deal:
- The phone boots well and if i connect it through usb to the computer i can even access the folders and all.
- I can take photos (i her the sound of the shutter and all and see the piics taken in the folder when connected to the computer) and screnshots
- I managed to restore the phone back to original settings and even update software with sony official soft.
- Inicialy i bought the phone as faulty to try and fix it since the buyer informed me there was no water damage ( and i can confirm this because the "stickers" only show white). He informed that the phone just stoped showing image on screen.
- I thought it was a problem with the LCd so i bought a new one and replace it. The problem persists. Everything works but the screen.
Any toughts on this one? Could the motherboard be faulty in only one place (image, proximity sensor, etc)?
Thanks for you time
Regards
Try the service manuals...

I have fully same faulty 2nd "spare parts" phone.
All works except screen, all as you described.
I checked, in my case problem definitely in screen because if connect main board to really working LCD panel = screen ok.
And vice versa: if connect normal main board to this probably faulty screen = black screen.
Maybe here broken flexible connector.
Also nothing interesting related to this case in service documents.
Hi everyone,
So I've had my LG G3 for about 3 months now. As of this morning, a particularly bad case of flickering set in on it, with the screen overwriting other parts with transparent versions of other sections of the screen. I've tried restarting the phone, pulling the battery with the phone on and off, removing and replacing the SIM card and SD card, etc. to no avail. This is particularly mild compared to earlier; before, it would "scan" a single line across the entire screen, fade to a solid black screen, or other major errors. The touchscreen and all physical controls still work, and as far as I can tell only the battery is a problem. I'm likely to be sending it in for tech support, but if between now and Monday I can find a fix, that'd be greatly appreciated. I've transferred my SIM card back to my original phone (a near broken Razr Maxx), and since restarting after that, the issue has almost completely gone away.
I have a recorded video of the problem, but I'm unable to post due to the link restriction on new accounts.
Any ideas?
I bought my beloved Huawei Mediapad M2 in January 2016.
After a recent sabotage, I had to send the tab for repairs because the LCD wasn't functioning. But a few days ago, my Mediapad M2's screen flickered although I already retrieved the tab from our local Huawei authorised centre and then the screen turned off when I received a phone call from my family so I can't pick up the call because I can't see whatever that is on the screen, how to fix this without having all my data becomes wiped out again? Yes, I have a lot of work saved in this tab.
Before you ask further about memory card, thing is, nope -- I don't use any, all files are saved directly into the internal storage of the Mediapad M2. I know the tab is still working because when I tried calling my number (which is in the tab) from another phone, the tab rings. So does when messages come in. And when I plug in the headphones I can listen to music from my tab.
I want to backup my files before re-sending the tab to the service centre because they might wipe off all data again upon rectifying the issue, but before that happens, how do I suppose to do the backup when I can't even see what's shown on the screen (because the Huawei HiSuite software installed in the PC requires confirmation of the tab being connected to the PC by touching on an OK button which is supposed to show up on the tab)?
Please help, thank you in advance.
I have the same problem
Did the screen turns like grey after a while ???????
Hmmm.... this seems to be a fairly common issue, from what I can see in my searches. Most of the threads I saw in my searches (see "references" below) recommend trying the following things. DISCLAIMER: I have not tried any of these methods; you try them at your own risk.
- Try a hard reset - keep the power button pressed until the phone reboots.
- Press VOLUP + POWER and see if that fixes the issue.
- Press VOLUP+VOLDN+POWER to boot into recovery and see if that fixes the screen issue.
- Let the battery completely drain (do not charge it for a couple of days) and see if it fixes the issue (note: this is a modification of a solution where people remove the battery, let the phone sit for 10 minutes and then replace the battery. Since we cannot remove the battery on the M2, we should just drain the power).
- This may sound stupid, but give the phone a couple of smacks. If it is some loose connection in your screen connector, this may (temporarily) fix the issue.
If everything fails, you may need to take it back to the store and allow them to factory-erase it.

I got it
So it's a problem on the flex cable that conect the motherboard to the screen, it cost like 9$.
And if when your tablet was ok you had "automatic scyn" on, when you reinstall all over again if you pay attention from what google say, it's like have your tablet with the same things.
I have this problem too
Did you already solve this problem?
I had the same issue. But you have to repair it yourself. Or have it done by someone who knows how to do it. The touchscreen is attached to the body of the tablet by a connector cable. This is probably broken.
You can order spare parts for this tablet online.
I found mine on ebay and AliExpress.
It is also possible the touch part of your screen, or the whole screen (LCD part and touch part) is broken. All parts are easily replacable!
If you need any further help on how to do this there are videos on youtube.
Good luck and I can post more specific details if necessary.
Hi,
Had my phone a couple of years, no problems, but recently cracked the screen.
Bought three replacement screens and fitted them in phone:
* 1st one touchscreen digitiser worked perfectly all the time but LCD was broken (had lines/artifacts on it) - sent it back.
* 2nd one, same supplier as first, LCD worked, but digitiser works intermittently - it always works immediately after phone reboot, but after the screen locks for the first time, it then has a problem where it registers an input when I'm not giving any, so the screen goes haywire and I can't even enter my pin or restart phone (Have to use red button in sim card bay). Occasionally and randomly when I try it, it sometimes works so I can enter my pin, and then use the phone until the next time the screen locks....but basically phone is rendered unusable, because this is totally random. Sent this one back too.
* 3rd one bought from a different supplier - AFAIK this one is a genuine Sony part (it at least has the Sony logo on it), but have the same digitiser problem as the second. Time has passed to send this back.
Due to the above description I am sure it is not a problem with the phone (1st one digitser worked perfectly & original cracked screen digitser worked for half the screen where it wasn't cracked). I'm also sure it's a software issue, since it works everytime following a phone reset but before the screen is locked. Behaviour seems to be the same at different temperatures. Also inspected the flex connector and ribbon components under microscope at work, and saw no problems.
One think I noticed is that all 3 screens I bought have no insualting backing on the back of the LCD, so the metal back touches the metal shield below - I did not see any screens to buy with the insulating backing - I wondered if this could be affecting the EMC behaviour of the screen (some capacitivie coupling with the digitiser or some type of grounding issue) - but then why would the digitiser of 1st screen work ok, and work for >1hour following a reset but then not after a screen lock?
Tried turning glove mode on/off - no difference in behaviour. Tried using screen while it is not fitted in phone housing (not touching metal shield), same behaviour.
I saw a couple of threads from a while back, but don't know if they are up to date, or if a solution to this problem is now known:
https://forum.xda-developers.com/showthread.php?t=2691849
This one gives a solution, but then says at the top of the thread DON'T TRY THIS FIX, IT IS A HARDWARE ISSUE NOT SOFTWARE.....so I'm worried to try it.

This one is to adjust the touchscreen sensitivity, but even though I have root access, I get an error message relating to the mount commandwhen trying to copy the edited idc file back to the system\usr\idc directory, "operation not permitted'.
Does anyone know a reliable fix that works? Or how I can get write access to idc folder to try editing the clearpad file? I don't have an SD card for my phone, but not sure it is essential for these methods?
Thanks

Assuming you're on LP 5.1... System rw access is disabled by default, even with root. Flashing dual recovery by NUT is easiest way to get it. Then you should be able to move files in boot or in recovery.
