so i think my wing may be in the process of biting the big one. A few days ago, my wing restarted itself for no reason, i figured it was probably a system error and didnt think twice about it. Now all of a sudden my wing will constantly restart, sometimes in the middle of a call. Sometimes when it does restart the screen will either turn white or fade to white. I reinstalled the original rom to see if it was a software issue and it is still doing it. Also, it doesnt normally do it when it is just sitting there, and sometimes i cant turn it back on. Any ideas?
Make sure the battery isn't loose inside the case... and that all the prongs are making contact.
For the life of me, i cant figure it out. I know it has to have something to do with the phone not getting power. At this point, it wont even fully turn on. Short of taking it apart and checking the solder, does anyone have any ideas?

If you already reflashed the original rom, and it is still doing it, that tells you it is definitely a hardware issue. It does sound like it's losing power which could be a host of things. (loose battery, defective battery, loose solder on board, etc) I would try what duprade said, and check to make sure your battery has a good connection first. If you had a friend that had a wing as well, you could try his to make sure it's not the battery.

Brand new battery (free from tmo to replace the dynapack) Everything on the mainboard looks like it is soldered well. There is an internal watch batter though, could that have something to do with it?

I doubt it. I would guess that's the cmos battery. If that were to go, then your phone wouldn't keep time, but that wouldn't stop your phone from functioning. (I used to work in the service center at a computer store).
maybe its the processor then. sometimes, after it freezes, it artifacts before shutting off

There is the possibility of you overclocking your phone, and it heated up and could have burned or cracked some solder. It might even be overheating and that's why it reboots. At any rate, it def. sounds like hardware though. Sorry man. You could try to resolder the connections on the board just to make sure, but it sounds like you have a paperweight. Is it under warranty or do you have insurance?
only ever oc'd once, for a few minutes, and not very high (like 267 i think) It's on right now on the power cable (this wouldnt work yesterday) I honestly have no fricken clue whats going on with it.
Is it possible for the battery to completely diminish itself without being used for a day? Before it died on me last, it had a full battery, now it is showing 1% (and charging).
By the way, as I stated above, it is a brand new battery sent to me by tmo.
Dang it all! Stupid thing just shut off again... ARG!!!

Hey dcmtnbkr. I seem to have the exact same problem with my Wing. It shuts off for no reason, and it does it absolutely randomly. Sometimes it would work for 3hrs straight no matter what i use it for. And other times it shuts off every 30sec. and it takes 3 to 10 tries to turn it back on(most of the times it would not get past the windows mobile welcome screen). I was gonna flash it with the newer Rom, but i'm afraid that the damn thing might shut off during flashing . So i'm stuck. If you find the way to fix it - please let me know.
actually, i just talked to tmo, and apparantly NOW after i told them I'm cancelling when my contract is up, now they can apparantly cover it under manufacturer warranty (as opposed to the last time i called about a week ago) I would call them even if you didnt buy it from them, tell them you dont remember where you bought it, but it was some company online. These phone's arent that old and you may still be under the manufacturers warranty. Also, i would try and flash it back to the original. These phones are very hard to brick, and i would ask around to see if a powerdown in the middle of an upgrade would do it. I just got mine to reflash without a problem.
my wing rstarts itself wen i jus tap the back of it where the battery cover is but it wont restart everytime. anyone have any ides?
Stupid thing is that I can do everything to it aside from getting it to boot all the way to work! I tried reflashing OEM roms and I tried custom roms. They all work just fine and it just won't boot all the way. I can turn it on and off, use format option, download mode and magldr. I keep my sim out and memory card. Before this all happened I always used OEM OS. Last thing I did was check my bank account, close the browser and click the power button to turn it into sleep mode. Few weeks ago I did have an issue with it for a day. It kept turning on and off constantly boot to random points. Mostly to the AT&T screen. It would boot all the way rarely and I got it to stay on a couple times for about 10 mins to copy all my stuff from it. Is it possibly something to do with the hardware being a POS and Just crapping out for no reason because cell phones are poorly made expensive bricks?
I've seen this issue across the forum several times. Unfortunately, just one case seemed to "return" to life, without understanding the reasons behind the "lapse".
What I can suggest you can do (and feel free to disagree) is get in touch with Cottula (creator of MAGLDR) and see if you can help you. You can send him the phone, maybe he can analyze it and get something out of it.
GL, mate, and if you find a solution, I'm sure other folks here would be glad to hear it.
Ahhh ok thats what I figured. I browsed a bit, but most of what I saw is people couldn't do anything. I didn't see anyone saying they could do as much as what I can do with it. I'll try your advice and see if maybe he could help. I took apart the phone to see if maybe someone came loose, though I saw nothing. Clean as a whistle. What I think maybe happen is it burnt up finally. I notice at times it would run extremely hot, mostly when I'm talking on it for more then an hour.
Well, for your sake I hope it's not burned out (hardware issue). I hope it has some software component that's screwed and that has a chance of being investigated and maybe fixed.
Also, the getting hot while talking/browsing for periods more than 30 min it's a known issue. It's however supposed to be quite warm, but not actually really hot, if you know what I mean. It it however possible that exposing the phone to higher temperatures to cause hardware issues.
In any case, I wish you good luck. Who knows?
I gave AT&T a call to see what they could do. The software warranty is 6 months past and she wasn't able to override anything that much passed over. Though I was able to get my 2 years wavered and get a early upgrade. So I got myself a Xperia Ion. I'm happy I don't have to put up with a flip phone for another 4 months. lol
I tried working on my focus a bit more playing with zune and other programs I found. Though I don't see it coming back to life trying all the different ROMs. I would think to make it work again is to re-flash the actual phone bios itself. Just like a computer starting it still uses DOS then loads the OS. I don't know how a phone works to much, but I'd assume same process. Something to do with the root-root of the phone telling it to be stupid and not boot properly.
Another note, where is the best place to sell this to get some money out of it? Screen and other pieces of its hardware are 100%. Should I try ebaying it?
I had a similar issue, last thing i did was removing the SD card before re-flashing the MGLDR and custom ROM
Hi, i have a SGH-I337M, with the AOSP 6.0.1 rom with root, since i can remember the phone had been pretty much hot, i didn't care much back then since i use it a lot but recently my phone started to freeze, like the screen freezes and i cant do anything, not even turn it off, so i have to take off the battery let it cool for 20 minutes and start it again, then it works about 10 or 20 minutes and then again it freezes i think it might be related to the heat. Also some few times my screen has turned green and then white and others few times i can see some sort of colored strings.
I'm pretty sure its hardware related but i don't know why it happens and if it can be repaired, do think ill have to change the whole motherboard?
Thanks in advance
Graphics chip may be the problem You shouldn't let your phone overheat like that I think it's the graphics chip (because of the color artifacts) You can try to reinstall ROM (clean installation) and flash another modem&bootloader, or even flash stock ROM. If that doesn't help then your graphics chip is damaged...There is 'repair', by changing motherboard, but it can be very expensive (if you don't find another S4 with broken screen or something else with working motherboard)
I already reinstalled the rom (clean install) and yupp, it doesn't work, the warmest place in my phone is between the sim card and the sd card, so i guess ill have to change my motherboard X_X
Anyway, thank you very much!

Have you actually tried other ROMs, or are you just a negativist?

You should get CPUTemp Xposed module and stop letting your phone get hot! I usually stop screwing around with mine when the temp gets to like 50/60-something Celsius. And like GDReaper said, don't be a Negative Nancy, be a Positive Paulie and play around with other ROMs!!
my original phone screen did things like that after a pretty heavy drop onto a tiled floor. it maybe a good idea to have a technician diagnose your problem before forking out money for parts that might not fix anything.
Thank you all for your answers, i did tried to flash some other roms without success (I still have the same problem) i am afraid to continue playing with roms since my phone sometimes freeze in the middle of the android configurations when i reboot my phone just after the new installation and i don't want it to freeze in the middle of the installation of a rom.
I think ill go to a technician to see what can be done about it, ill keep you informed what was the problem
Today on my way to work I was playing music through my bluetooth and the music stopped. I went to reset bluetooth and it took almost 3 mintues to turn off. When I went to turn it back on, it wouldn't. I powered off and reset the phone. After, it got stuck in a bootloop. LG logo for about 7-8 secs and restarts.
Before the bootloop, I was noticing a few weird things: A notification of USB Options was always up, was saying I was using my phone as a USB Power Supply. If I changed the options it would revert back to USB PwrSply. I noticed the battery life was getting a lot worse. Also, when plugged into Quick Charge it would not say "Quick Charging" anymore.
I can get into the Recovery menu, but all options revert to the bootloop.
I can get to the Download menu. After about a few seconds of sitting on the Download menu, it starts the LG logo bootloop.
I have not tried to flash another stock ROM. I have downloaded the LGUp program, Uppercut, LG Mobile Support Tool, and LG Mobile Driver. I also downloaded the previous 1BA firmware kdz file.
I believe I have the knowledge to reflash properly, but I do not want to make the phone worse or lose my data. Plus, I don't want to void the warranty.
TL;DR I have bootloop and want to save my data!
Any suggestions would be very much appreciated! Thank you!
Flashing won't help you, this is a hardware problem. You can try freezing then phone, seeing if it will boot, and then backing up your files a fast as you can. Alternatively, if that doesn't work, you can take a hair dryer and heat the phone up.
Either way, LG will definitely take care of it under warranty since those morons can't seem to make a decent heat sink that lasts. Every LG flagship phone since the G4 has had this problem. I am sure the V30 and G7 will be no different -- they just haven't been out long enough yet.

I was hoping that this wasn't the issue. I was hoping that it was from the 1CA update, because the other random problems seemed to have started when it updated. Should I at least try to reflash? Would reflashing to a stock/OEM ROM (the one i mentioned above) void the warranty?
Also, when I restarted the phone today, that was the first restart that I have done since the update. Not sure if that means anything, but maybe??? lol
No, flashing a KDZ does not void the warranty even by LGs terms.
In the US rooting your phone doesn't void the warranty either .. no matter what OEMs will have you believe.

Awesome! That's definitely good to know. Thanks.
I'm going to attempt to downgrade flash it. If it doesn't work, I'll contact LG. I dont really care about buying a new phone. My data on it is worth WAY more to me than the phone. (Guess I really should start backing up my stuff XD )
If you have any suggestions as to recovering my data, even if it kills the phone, I'm all ears!
Update: I attempted to flash or just access the phone as storage using many different ways. While I was browsing for new answers, I kept the phone connected to my computer and left it bootlooping. Eventually, the phone battery died and booted up properly. The battery was at 1%, but everything loaded just fine. I was able to recover all my data and save it to my PC.
Thinking that this was a soft-brick due to the phone actually fully booting, I was going to attempt to root and flash. I let the phone charge to 100%. When I reset the phone to implement the root, the phone got stuck in a BOOTLOOP AGAIN.
Any ideas in why this would happen? Does this mean it's a software based bug, or hardware?

I'm not sure to be honest, your situation seems strange
Was it hot and was your phone in the sun during your trip to work? Overheating can make weird things happen.

It wasn't hot at all, I had the A/C in my car on and it sets on a car mount that mounts to the air vent. It gets direct A/C. I didn't have it charging either.
All I did was connect my phone to Bluetooth, play a mix, and drive 15mins to work at 6am in the morning. It was still dark and cool out. The music stopped and I tried to reset bluetooth. It took forever to turn off and wouldnt turn back on. I reset phone and BOOTLOOP. ???
There is no damage to the phone physically. I don't think I've ever dropped it ever. It's gotten hot a couple times, but that was months and months ago.
I've never had a problem with this phone since I got it almost 2 years ago, since the 1CA update, I had a couple bugs, now this bootloop.

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
