Hey so this is my first post ever, and im really sorry if i put it in the wrong place, if so mods can you do me a solid and move it?
Ive looked around the forums and didnt really seem to find anything on my issue, but my Lg quantum's touchscreen locked up on me. It is completely Non-Responsive, i thought maybe i messed something up in the registry so i did a cold boot and now im stuck at the Welcome to your LG LG-C900 windows phone screen and i cant hit anything! Any ideas what could be causing this to happen, and/or how to fix it? Thanks in advance for any help you guys can provide!
when (if) you did your update to 7008, it should have made a restore point for ya. if you hook it back up to zune theres a restore button in the update page. might be worth a shot...
Hey buddy, thanks a lot! Im gonna give it a shot now, im putting it back together as we speak! If i havent updated it could an update maybe fix what was wrong? If that doesnt work, is there anything else we can try to do to fix it? Anybody know a good tutorial for me to take it apart?
***Edit***
Hey so im having trouble putting the phone into emercency download mode, im trying to work from the thread here , http://forum.xda-developers.com/archive/index.php/t-935605.html , and im confused at the (VOL+CAM+PWR) i hold those and nothing happens to enter a download mode.... anybody have any advice?
i read somewhere that for the (VOL+CAM+PWR) to work, your phone must first be off first.
and idk if we are allowed outside links here, but THIS looks like the same link as your just on a diffrent site. maybe some searching on that site might bring up something...
So an update, after much tinkering with the phone I found that to get into emergency download mode you must first:
shut the phone off
slide open the keyboard
hold space then press power
it goes to download mode instantly
Sadly, updating the firmware manually did not bring back my touchscreen =[
Any other advice? Or somewhere i can go to learn to take apart the quantum properly?
Please post in the proper device forum! I will now move your thread. Please remember to look at the stickys up top, and to look at all the device forums before you post.

Did your digitizer go out? I broke mine -_-
Anyone find a guide on how to replace the digitizer?
Did you get the phone from a supplier (e.g. Bell, Sprint, AT&T)? If so, you might be able to contact their Customer Service to talk about repair/replacement...
I does sound like you have a hardware fault -- not something that can be fixed with firmware, etc.
I just took apart my quantum and found an amazing service manual for it if anyone needs it. I had the same thing when I put it back together but I had just unplugged the digitizer and didnt plug it back in. Ill put up a link to the file if anyone needs it. I gotta also say I friggen love this phone. I apparently knocked it off the table one night into a pitcher of Koolaid. It sat there for hours. In the morning I picked it up and poured a glass and there is my quantum at the bottom of the pitcher. I was livid. I just pulled battery out, dried it, gave it an alcohol bath, opened it up and put it in a tupperware container of rice for 24 hours, then used a hairdryer to get any remaining liquid in there dried. Put it all back together and the only thing wrong with it was water in the LCD. Just replaced the LCD so I can see better, (it was only annoying, but perfectly functional). Digressing... SO I found the service manual and even made a youtube video of the basics of taking it apart. Ill post the links in an edit.
The video sux I know but it was only because no one had one up yet, so I had to post it to show what I found out and what troubles I had etc.

I think I'm in the right area of the forums...ok here's my problem. My phone was working fine all day but for some reason when I slid the phone shut after sending a text the screen just started flaking out! It looked like a broken T.V. set. As soon as I slide the phone back out it immediately clears back up?!?!? So thinking it was a software issue I did a hard reset. That didn't fix it. I reflashed to dcd's 3.2.6 rom. It's still doing the same thing. As I type this I am downloading the factory rom from htc's website and will reflash and check that out but I do not believe it's gonna help. I'm no stranger to phone's. I have replaced the screen on my titan twice but I don't wanna take it apart unless I have to. Any ideas guys??? I know this is not a popular thread topic but I really do not have the money to get another phone. Please help guys!!!
sounds like a bad ribbon cable.
So, as I cant leave things alone.....come on, who can right?.
Verizon Tab....
Im a Droid X kinda guy, we dont have Kernals (thanks Motorola ) so sometimes this stuff gets confusing, so many options right....
Flashed the VZW Kernal after a few attempts, worked, started messing with Roms, ok cool. Started backing up using CWM, ok cool.
Here is where **** goes wrong....
Started tweaking rom, went to reboot, typical boot loop, no biggie, Odin and Heimdall are my best friends, infact at this point I think my 4 year old has seen me use them enough that she can do it, lol.
decided to nuke and repave, but the usual factory files failed halfway through, wtf?, so I got the Phone---!---PC icon, whoops.....
Did some heavy ready/searching, seems there is not to much out there for detailed info on this.
Found a few posts scattered, one was a system dump, and the person said he flashed everything to repair, so I decided to follow instructions, big giant huge EFF-UP !!
What I know now, after all is said and done......
I flashed the bootloader.
Well, now I know.
So, it happens that VZ tech was nice enough to still send me a replacement, I tell them the truth, they know my DX has the GB leak, wifes Dpro is rooted/rom, etc.
Lesson....
um, dont flash boot loader? ha ha ha.
Oh, I did crack the Tab open, took battery out, looked inside, real ***** getting back cover off, looked real good at cover, possible to airbrush/change colors though...
The tab is not really bricked if you can power it on. There is still a way to "unbrick" it.

Phone-!-pc icon is download mode, so you were not bricked. Usually, just reconnect to the pc and flash again.
Where did you get the three blade screw driver to open your tab?

Tab doesn't turn on anymore after accidentally flashing bootloader, no response. not even if I plug it into wall. button commands dont work either.
I have a wood shop, and alot of tools.

You're not the first to do that. Use three wall charger for at least four hours, and try again.
In the stickie section (you can see that part of the forum if you view with a pc) there are some instructions involving some button sequences and the usb cord. But you may have to send tab away to samsung for a clean flash with a JTAG Box.
What is the name of the 3-blade screw driver, and where can I get one? It seems gorilla glass is a farce.

New one arrives tomorrow, Im not going to worry about the bricked one, Ill send it back.
Dont remember the name of the screwdriver, I have alot of strange small tools, large collection of bits, you can get away with a regular small bit.
Taking the back off was a huge *****, you wont break anything, just a pain. Battery is huge, and a good majority of the weight.
Hi there,
your first thought might be: Ah jeez another one posting the same **** 2000 people posted before ^^. But anyways i think my problem is a special case:
yesterday i wanted to flash another radio to my htc magic via clockwork recovery. However something must have gone wrong. After the recovery rebooted my phone i got stuck at the "htc magic" splash screen. Pressing the home or the back or vol-down button or home and back button at the same time doesnt change the situation. still stuck at splash screen. fastboot and recovery dont seem to work.
After some really bad panicking minutes, i pulled the batery out of the phone and let it rest, while googling and searching the **** out of every forum on the net. Some minutes later i reassembled the battery and started the htc magic without pressing any other buttons, hoping it would juts boot and say "kidding ))" on the display. but yeah ... it didnt ^^.
Now im coming to the odd part, which differs from most other posts i saw on other forums and here on xda: after quite a while my htc magic suddenly made that "bling bling" sound, as it did whenever it started android successfully. i nearly burst into tears when i heard that sound, hoping that i would be able to access the phone via fastboot or adb. but ... i wasnt able to :S. the screen went black after that "bling bling" sound and stayed that way until i pulled the battery again.
i could repeat that procedure and reproduce the sound and behaviour, but i couldnt access the phone via any possible way i could find on the web :S.
hopefully somebody, who knows more can help. my last step would be jtagging the phone. but the tools are kinda pricy for such an "old" phone. and i couldnt find anyone in my area who could borrow me the tools or repair the phone for cheap money.
thanks in advance im counting on your knowledge
Try this low cost JTAG
tested by me with 2 T-Mobile Mytouch 3G
thanks for your fast response. if jtagging really is my last chance:
- what did you pay for all the parts of the schematic ?
- how long did it take you to put everything together?
- do i need a parallel port on my computer, or is it possible to use an usb port ?
- and do you think a newbie to smoldering and stuff could be successfully assembling all those parts?
- can you provide me with links and/or other pictures, which could help me?
thanks again for your effort
kinda exciting this whole thing :>
Teenage son swam with his one month old LG G2. Ouch.
Used reviveaphone liquid as only 12 quid and worth a try. I'm amazed but it actually seems to have worked, except I think in water shorting the phone we've lost the root because on the firmware update screen I get a message "920K 8100 Unrooted" appearing in a rectangular box at bottom of screen.
I'm a little computer savvy but know nothing about mobile roots. I imagine this is the built in Rom that fires everything up which has got corrupted by the water. I realise I might be wasting my time and it may be fried but being only one month old I want to give it a good try before binning it.
I don't want any hacked rom or anything complicated just want original rom restored if possible?
I expect there's a sticky that someone can link me to? I'm not completely sure which model I have but the back is off and maybe there's some identifier in there?
Sorry to sound terribly dim! Any help most gratefully received!
If you do reply can you please bear in mind I know none of the technical terms! Thanks
Okay, so the device is working? Does it boot into a workable mode or are you only getting that box with unrooted text? That doubts like you're in download mode.
Without knowing which variant you have, this is going to be tough. Start with this thread: http://forum.xda-developers.com/showthread.php?t=2705259
That should link you to everything you need to know to get back to stock rom.
This link will take you to a thread which will use a program on Windows to get back to stock rom as well.

Hi, I have a LG K20 Plus. I currently can't turn the phone on, so I don't have much software information to give you. The phone was bought at T-Mobile (Metro by T-Mobile) and I had a SafeLink sim card and a 16 gb micro sd card inserted when the issue started. I have since removed both. It says Qualcomm snapdragon on the screen when it starts. It was also rooted and the bootloader is unlocked.
I broke the screen on my phone and I decided to do the repair myself. I have done about 7 or 8 screen replacements and I actually did this phone a year ago with no issues, so I felt I could manage this one as well. I bought an entire display (from ebay) and switched it out with no problems. Initially it worked great! I used it for a few days before realizing that I had no sound. I opened it back up and noticed the loud speaker had fallen out. I found it, put it back in, reassembled it as I normally do and turned it on.
NOTE: when I was reassembling it the second time, I actually tried to put a screw in a hole that wasn't a screw hole. I used a light to normal amount of pressure but I didn't force it. I think it's the hole where the moisture detector is. Picture #1
I turned it on and right after the logo screen I got a message that said "High temperature detected Powering off for your safety" and it immediately shut off. The phone does appear to charge normally but it won't stay on. I did a factory reset (I'm not sure if it's still rooted but the bootloader is still unlocked). I also switched back to the old (broken) display just to check if that would work. I couldn't see any difference in the shielding but I switched them just to be sure. I bought a new battery and installed it. I took a q-tip and 95% Isopropyl Alcohol and cleaned pretty much the entire motherboard, paying special attention to the battery connections. After each one of these things, I tried to start it with the same error message immediately upon start up.
NOTE: At no point has the phone every physically felt hot or even warm. I don't think it's on long enough for it to get hot. But something is wrong and I have no idea what it is. I, literally, took the phone apart, put in the speaker and put it back together in less than 5 minutes. Could it be I just bumped something and knocked it loose?
I searched for any information I could find both here and with google but there is next to no information on the LG K20 Plus. I did find some information on the LG V20 that had overheating issues, and that has been all the luck I've had. I watched several videos and it seems the solution is to apply thermal paste. But my phone doesn't have any evidence that thermal paste was ever on it. I went and bought some but I have no idea where exactly to put it or even if it's needed. Most videos showed people using some kind of aluminum foil but I'm not sure if that is safe. I have several old phone laying around and I managed to get some of the silver tape and a copper square thing but, again, my phone did not have these things to begin with. I don't want to start adding things only to make it worse.
There is a slight difference of the tape that is on my phone now (the display I just bought) as compared to the old one (broken display). Picture #2 Again, I have no idea if that means anything but I thought it worth mentioning. Picture #3 is how it looks now as if I were going to put it back together. Picture #4 is the part (don't know name) where the videos show to apply the thermal paste and the shielding.
I'm really at a loss as to what to do next and I can't really afford to take it in to have it repaired before next month. If anybody has any insight or answers as to what happened, I'd be very grateful for your help. I'm sorry for the long post. I just wanted to tell you everything I have done in detail. Thank you
If you're using Kernel Auditor or any other kernel adjustment simply reset to default and use only ondemand or interactive. There's also options for the thermal portion of the kernel, don't mess with those. If VCC or another thermal option was checked off turn it back on. Putting the GPS to the moderate setting (the one below high accuracy) will keep the temps down as well. Are you using a custom ROM? If you're on Discord you can feel free to message me SCOPE★ BRΞΛD #8460 . I am only offering that so we can get this resolved quickly for you, just copy and paste since I use special characters.
Omgosh, thank you so much for taking the time to respond! Although I'm sure everything you are saying is very smart, I have absolutely no idea what you're saying. I'll do my best to try and answer you. I don't know what SCOPE is or how to send a message there. I don't think I'm using any thing for the "kernal". Also, I don't know what VCC or Discord is. As far as turning off setting for GPS or any other app, the phone will not stay on. I get about 1 sec after the logo when it boots up, then the error message about overheating and it immediately shuts off. I did a factory reset so everything should be good to go as far as apps. I don't think I'm using a custom ROM. The only thing I did was install TWRP, unlocked the bootloader and rooted the phone a year ago but nothing since then. As I stated earlier, this happened right after I did a display repair. Is there something on the MOBO that can get bumped that will make your phone get hot or send a overheating error. My phone doesn't show any sign that there was ever thermal paste on it prior but should I add some now. Will that help?
Update... Now the phone does not power on at all. When I plug it in to charge it I get an error that says "Device temperature is too high or low. Please move to another place to charge. I wonder where you went. I googled SCOPE so I could sign up to message you like you asked me to but nothing but definitions came up. I know I'm out of my league here. You guys all talk so technical. I didn't understand one thing the person asked me for. I know it's rare to get a response as quickly as I did and I was so happy to see someone had responded. Now, I just feel stupid and defeated. I thought this site was inexperienced with cell phones friendly. I'm just trying to get help so I don't have to go out and buy another phone again. Can someone refer me to a site that is more directed toward people who don't know much about the technical side of cell phones... please! Again, thank you for your time.

Hey, I just wanted to say sorry this happened to you. The same thing happened to me. My LG K20 Plus, no matter what button combinations I push and for how long I hold them, will not turn on or go into download mode. Plugging it in to a charger or PC does nothing either. Before it got to this state, I got the infamous green screen of death/Demigod crash handler (google this--it's a known issue with some models of LG phones and it happens when they overheat). It's definitely a hardware/build issue, and especially since this issue keeps the phone from turning on or connecting to a computer, I don't see a workable fix short of buying a new phone, unfortunately. Again, I'm in the same boat so I'm not happy about it either. I would say XDA is by far the best site to find a fix to this sort of problem, so if no one here has any suggestions on how to fix it, I think you (we) may be out of luck.
Thank you for letting me know. I'm not sure of some of what you said but I did catch the bottom line. Basically, just hold onto the phone until someone here comes up with a fix or workaround? I have a question for you. Did your problem start after you did some kind of repair? I'm wondering if I bumped something on the mobo to make it give a false overheating error. Do you happen to know where that sensor might be located? Sorry you are having problems to. It really stinks when your phone breaks and no matter how much time and energy you put it to figuring out the problem to fix it, there just isn't any good answers out there. I wish you lots of luck and if you figure anything out, please update here so I can try it too.
You need a whole new phone.
That or you're gonna have to replace the hardware
