[Q] LG D800 big problem - bricked? - G2 Q&A, Help & Troubleshooting

Hi,
I have a big problem with LG G2 from At&t. I've bought on swappa.com for using in Trinidad. When I bought it, It was running a 4.22 stock and rooted and unlocked. Everything worked well except quick remote.
After some time new (last week) the phone started to freeze and reboot about 5 times a day. Sometimes when it was rebooting it would cycle on/off a few times before it would boot successfully.
I thought it was just a software error so I had done a factory reset and install the stock rooted 4.4.2 rom but still had the same problem. I even tried cloudystock 2.2 and had the same problem all with no additional apps installed.
Is there any way to troubleshoot the error? Is this a software or hardware problem?
It there anyway from this mess?
Thanks for every suggestion.

Same issue
Hello,
I am having this exact same issue. Did you ever find a fix for this? I have been searching for hours. I have tried numerous things, flashing back to stock with lg flash tool, installing different roms, it happens on all roms.
Thanks

For me it was a bad motherboard. I ended up buying a tmobile board and replaced it. Everything worked fine after. Try a battery change first though. That might solve it as my battery was bad and maybe that made the motherboard go bad as well. I bought a motherboard off ebay so that's where I sourced it if you want to go down that route.

Thank you very much for your reply. I was actually wondering if it might be the battery. I will try that first. Again thank you for the reply.

HELP! My Phone is Slowly Self-Destructing!!

Hey guys, I am kind of a noob but have successfully been hacking with my Touch for a while now...or so I thought. I flashed to the 3.37.78 radio a while back and have been keeping up with NSFAN's ROM's for over a year now with no problems....until a few months ago. My phone locked up and I had to soft-reset but to no avail. It got stuck on the startup screen and would not do anything so I did a hard reset and all was good. Then it happened again weeks later. Now it has been happening a lot more recently. I will be texting or on the internet with it and then all of a sudden it will lock up, I do a soft reset and it will hang up either on the startup screen or seem to boot up but then contacts will be missing and there will be no signal. Sometimes the today screen will show but I cannot do anything on it.....all of this requires a hard reset to fix. This happened after I flashed NSFAN's latest ROM so I flashed back to some of his older ROM's that I had no problem with in the past and still the same problem. It has been happening every week or 2 now to the point that I can't even bother setting up the phone the way I want because I know it will happen again. Can any of you guys tell me what the problem is? I really need to get this resolved because I am losing information everytime. Please help!!!
Im a GSM Phone user... and as a general rule, if things start to go wrong.... Flash the OEM rom. That would be the stock ROM. And then flash back to your "custom" rom... Ive had to do that with my phone(s) as well.... It basicly puts things back to 'ground zero'. BUT. Use the phone with the stock rom for a day and see if you still have the same problems... it may be a problem in the phone. In which case you may need to replace and/or send the phone back for replacement to your carrier.
Hope this helps....
Thanks for the reply.....What I ended up doing is reflashing my radio to the 3.42.50 version and then reflashing my ROM to NSFFAN's again. So far so good. I am really hard on my phones and the fact that I drop my phone on a regular basis can't help either....I just need it to last me a few more weeks until I get a new one. Thanks again...

[Q] D803 Phone freezes then reboots every few minutes

What's currently happening is my phone will boot and work normally except it appears the radio is not working then after 60-120 seconds freeze for a second then reboot. Wifi does work but I just see an x for the cell network signal and if I take out the SIM I get no notification. Curiously if I'm using the camera it seems to delay the rebooting by a few minutes.
I've tried http://forum.xda-developers.com/showthread.php?t=2432476 LG G2 Stock Firmware (Go Back to Stock) to no success, I was able to flash, it removed TWRP but I get the same symptoms anyway.
I've tried flashing the Rogers modem and this did not make a difference.
When I noticed this problem was when I was installing/testing some xposed modules, although it seems strange that they could break the phone in this way.
I've run out of ideas and although my phone isn't bricked per say it's near useless if it's going to reboot every minute or two. The phone doesn't reboot if I leave it in download mode or TWRP so this makes me think there's some hope.
Assuming it's not against the rules I'll PayPal anyone who comes up with the fix $50 CAD because right now I'm hooped.
Did you download and try flashing the exposed disabler zip file?
Sent from my LG-D803 using XDA Premium 4 mobile app
Of course there is hope!
All you gotta do is just download this ROM...
http://forum.xda-developers.com/showthread.php?t=2451592
Download it with your PC, then connect your phone to the PC to transfer the file.
The TWRP and flash it and that should fix it all.
Good luck
Do you have a gmail widget on your lockscreen? (Was worth a shot since others have reported varying issues with gmail widgets on the lockscreen).
I lost my recovery when I tried to go back to stock, and I can't seem to install any apps. I'm trying "upgrade recovery" from the LG Mobile Support Tool to see if that works. Otherwise I guess I have to find out how to root and flash a recovery entirely over ADB
I was able to restore the stock recovery and factory reset but that still didn't resolve the issue. Can someone provide a /system/ partition dump of a d803? I'm assuming there's something broken in there but I don't think flashing a ROM will solve that since flashing stock didn't seem to.

If flashing to stock didn't work then your phone may as well be defective...

It's not a paperweight yet, I can adb. I rooted it through adb I'm just not sure what the xposed module broke. It has to be something that persists across flashing stock but I don't have anything to compare against.
EFS. Flash or push your backed up EFS.

I don't have one. I made a backup in TWRP but ended up losing it when trying to fix things :silly:. I believe I can still see my IMEI if that's any sign of things not being completely ****ed.
Hi I have LG G2 D802 . My problem is that my phone hangs a lot . I did hard reset but problem didnt go. After hard reset i tried to install custom built rom but still same problem. Then I re installed lolipop 5.0.2 still the same problem .. now
i have downgraded to kitkat and again same problem .. Even now when it hangs It turn off completely like it got bricked or something but it work some time and again after some use it hang.. now i have hardreset my device and putted on standby mood but phone was working fine after some use phone hanged again . I dont understand what is the problem with my LG G2
I am having the exact same problem on stock 4.4.2 with my D803. I have random reboots every few minutes. I suspect it is a hardware issue since the problem persisted even after returning to stock using kdz. Unfortunately, I don't have an EFS backup.
I have tried multiple other ROMS (CM12.1, DU, Cloudy 3.2 and 3.3) and all are even less usable than stock (reboots while I am doing the initial setup).
Any suggestions? I don't know what else to try and am ready to buy a new phone now as this G2 is basically unusable... I'd greatly appreciate any help.

If you have restored it to stock ....... and you still have the problem, u may have a short somewhere in the phone. The only thing that remains the same is the hardware .... u have changed the software

Nexus 7 not starting

Hi,
I recently rooted my nexus 7 and flashed TWRP recovery. One day I got into the recovery and started playing with it. By mistake, I erased my OS. I then came to know to know that i could fix it by flashing a custom ROM. I installed a custom rom successfully. I then wanted to go to stock. While flashing the stock OS, it got stuck in bootloop. It was too late so I thought to flash it the next day. On the next day, when i tried to switch it on, it did not start. I kept it overnight for charging but it was of no use. Then i went to the Asus service center, and i came to know that there was a motherboard problem. I did a little research on google and came to know that to earn money they told it was a motherboard problem. Many people had fixed it by unplugging the battery and replugging it back. I tried that, but it was of no use. I did not play with the bootloader. But now I think that it could be hard bricked.But I am not sure. So any idea whether it is hard bricked or really is the motherboard spoiled or what??
Thanks in advance

Samsung Note 4 N910F is not stuck in bootloop, still doesn't really boot

Hey everyone,
I have been looking around online for several days now, but haven't been able to find a description of the problem I have with my n910f nor a solution.
When I got the phone it was stuck in bootloops and so I though it was soft bricked.
After I installed the custom rom and the latest version of TWRP via Odin, I thought that the problem was fixed, because the phone booted and I was able to start the configuration of Android (where it asks you for language, time zone etc.)
However, the phone turned itself off during this process. So I wiped everything and tried again, the same thing happened.
I then flashed it with Lineage, but it would turn itself off even before the logo appeared.
Then I flashed it with Ressurrection ROM, but again, the phone turns itself off during booting.
I can access download and recovery mode without any problems, I can flash roms and Odin works like a charm. I also used 2 different batteries.
Does anyone has an idea what I could try? Could it be the version of TWRP I am using (3.0.2.0)? Or is it a hardware issue?
Thank you!!
Hi, I have this exact same issue with my N910T and so far haven't found a solution to this. I really love my Note 4 so I'd like to know if this issue can be solved or not. I event went to a supposed repair shop and they couldn't figure out the problem, guess they weren't that good.
Sorry to hear this.
I have found issues that seemed similar, but not quite the same, and people hinted that it could be a worn out motherboard that is causing this top happen. But before I open up the phone (at the potential risk of breaking at least the screen) I would try everything else.
Or is there a way to test whether the motherboard is defective?
Its the plague of overheated, worn out emmc memories, sadly. Once it happen,the only way is a new/used motherboard,prefferably C model.
eMMC failure, snapdragon models are susceptible to this.

I suggest flashing stock rom with Odin after wiping your whole device in TWRP. I've had the same thing about 2 months ago.
Hey,
thank you for your responses. Yes, I read a lot about it being a motherboard problem.
I got it to work now thanks to this post: https://forum.xda-developers.com/note-4/general/downgrade-official-mm-to-kitkat-t3383885
First nothing happened, but after I flashed Modem and the original Bootloader again (after installing the rom) the phone turned on and I was able to use it for a while (20mins maybe). Then suddenly it turned itself off and stayed on the "Samsung Galaxy" screen for a long time.
Apparently a lot of people are using Wakelock and it seems to be working for some of them, but that seems to defy the point somehow.

Which Stock Rom did you use exactly? Is your phone working fine?

I need help, my tablet is not working anymore.

Can anyone tell me if the tablet's battery might be responsible for it restarting itself? For example I was using it with a custom rom, and until the moment everything was working normal, and suddenly it started to restart, just by opening an application it crashes and reboots, I already tried to install the stock rom and it got worse, I could not even leave the samsung logo. I was able to install TWRP, but every time I try to reinstall the stock rom before it even starts it hangs and restarts, it has reached a point that it hangs and shuts itself. (Backup from twrp).
My tablet is the model SM -T560, I was using LineageSo 14.1 from T561. If anyone knows anything I appreciate it. The reason for the doubt is because I already took another tablet to repair and according to the technician, that could be the reason, the system was crashing, but from what I researched it was a chronic defect so I did not perform the battery replacement. Now i don't have any money to bay a new battery, and the device became an expensive paperweight.
Help please.
Hello everyone, for those who are in a similar situation, in which the tablet can not open an application without it restarting, reinstalling the stock rom and it keeps crashing and restarting, tried everything via software and did nothing for nothing. The battery arrived today and I'm testing to see if the problem solved and so far everything seems okay, I hope I can help with something.

Uhm Yeah you can help with something, Sorry I wasn't a member when this was posted. Do you by any chance have the CM12.1 Custom ROM for the SM-T561? it's okay If you only have one for the SM-T560
