The unit has been used for about 2 months and remains quite new. It was quite stable before. Yesterday night, about half an hour after plugged in for charging and with WiFi Hotspot turned on for sharing 3G data to another netbook, the unit suddenly rebooted itself. It then stopped at the start-up screen and remained there for several minutes. I kept holding the power button for a few seconds to turn it off but it then automatically reboot itself afterwards, and stopped at the start-up screen again. It means that even complete turning off is not possible.
Trying to enter into recovery mode showed the following few lines:
# MANUAL MODE #
-- Updating application...
Copying Common Apks.
Click to expand...
Click to collapse
and then it automatically rebooted again. It means that it can't enter into recovery mode normally.
It was possible to enter into download mode. And it was the first time this machine went into download mode. I run Odin Downloader and flashed the official stock ROM. After showing "Pass", the device rebooted itself. Unfortunately, it still stopped at the start-up screen, just showing "Samsung Galaxy Tab 7.0 plus". It is really troubesome. I have experience playing several Android devices before and it is the first time I face such troublesome problem.
The device is an official product. The biggest problem is that the original purchase invoice was lost and most likely that I couldn't get official support, repair service or replacement.
May I ask if anyone would kindly provide me some help or advice. Thanks!
Instead of going into download mode go into recovery mode and see if there are any errors. Your scenario is sounding very similar to the one I had in the past.
I just ran into a nasty snag at boot logo as well. nandroid, stock kernel and factory reset were no help. Try Odin back to Stock, it still may not get past boot logo, hold vol up and power to get into recovery and factory reset. Hope it works for you.
Unfortunately I was unable to get into recovery mode even after odin flashing stock ROM.
It rebooted itself a few seconds after displaying some lines of text. I can't see the normal recovery menu.
Okay so I'm pretty new to the whole forums thing so please bare with me a bit. I flashed CloudyG2 3.1 and wanted to do a a factory reset so that I could start anew but whenever I tried doing so it would fail and lead me to TWRP. So I tried doing the format through there and then that's when I believe it even deleted my OS. Now the only thing it does is sit at the LG boot logo while the notification light slowly flashes blue and green. I can still go into TWRP but am unable to go into download mode. I've tried sideloading but whenever I connect my phone to a pc (I've tried multiple cables and pc's) I get a message that says "The last USB device you connected to this computer was malfunctioned". I went to get my port replaced and they said the screen stopped working so they put in my old one. I don't know if I should just get the port switched to the new one and try to flash it and pray the screen turns on afterwards or is there a way to get this USB to work. Any advice would help a lot! Thank you!
Device is a LG G3 D850, rooted, TWRP installed, stock ROM on 5.0.1
Here's the story: Yesterday I was browsing normally when the device froze up, then shut off. Wouldn't power on with the power button. I had to pull the battery and then it turned on. When the device booted back up, it was running very sluggish. Immediately noticed that the WiFi was constantly trying to turn on with no success (When entering the WiFi menu it only said "WiFi turning on"). Bluetooth would not turn on either. The battery was draining rapidly, about 20% in 30 minutes with no use. GSam Battery Monitor reported that Kernel (OS) had used 95% of the battery. I tried rebooting the phone with no success. Booted into recovery and cleared cache, no success. Couldn't find anything online besides people saying to try a different ROM/Stock rom or that they were told it was a failed motherboard. I tolerated using the phone into the night, but the battery was constantly draining and the phone temperature reported ~98 degrees even without use. The WiFi and Bluetooth never started working. Today, a few hours into the day, the phone shut off again. This time it started boot looping, going from the LG splash screen then the spinning AT&T screen, it would then hang and reboot (constantly boot looping). Battery pulls didnt help. Once or twice, the phone actually booted into the OS. After a minute it would start bootlooping again. I then booted into recovery and performed a factory reset. After the factory reset, the phone still bootlooped. I then booted into recovery and recovered to a previous nandroid backup. The phone booted up afterwards, with the WiFi actually working. After 5 minutes, the WiFi stopped working again and the phone proceeded to start bootlooping. My next attempt was to flash back to Stock ROM, using this method: http://forum.xda-developers.com/att-lg-g3/general/unroot-return-to-factory-stock-att-lg-g3-t2820827. The flash worked successfully, booting into the OS on the setup screen, but instantly started bootlooping again... The bootloop is a little different now, going from LG splash screen > Green android with blue spinning circle in his stomach > AT&T splash screen > then rebooting. I cant even get into TWRP now (When trying to boot into recovery and clicking yes on the default factory reset screen, it just reboots instead of going into TWRP) Im out of options, should I give up and buy a new device, or does somebody have any other suggestions?

Sadly that is because of a hardware issue. Been happening. A lot lately.

Alright, that's what I had read. Just seemed like a software issue so I was hoping for the best. I went ahead and ordered a new device. Im guessing a full motherboard replacement would be required to fix the device?
Recurring Issue
Hello,
The same problem happened to me a few days ago so this is trully a recurring issue.
I also tried to fix my rom by reinstalling it, then tried to install multiple new rom, and finally flashed the original stock rom. I also am stuck on the bootloop issue.
I'm going to contact LG to see if they can do anything to repaire it but my hope are very low.
I'll try to update this message if I find a solution.
Mine just started bootlooping and no wifi and today it just died. Battery pulls didnt work either no power at all. Probably going to switch to the V30 when its released.

It's probably to late but theres another method returning to stock KitKat dont know the link off hand in development forums. Sucks you couldnt try no adb methods. Still have the Phone want to sell it i need a cheap screen ?
Hey guys, I've got a Kyocera Brigadier and I decided to change the runtime from Dalvik to ART. Now the phone is stuck on loadscreen and I don't know how to fix it. The phone is rooted using the KingRoot app, but I don't know if that would help in any way.
Please help me guys!
Similar Issue
I am have a very similar issue, I also rooted my Brigadier with Kingroot and all went well. However, I attempted to flash the Xposed Framework onto it using Flashify. After doing such it got stuck in a bootloop, I was able to fix that problem by booting into fastboot mode and using fastboot to push stock firmware back onto my device. However now I have an even bigger problem where my phone boots up to the Powered by Android screen and then to the Kyocera screen, however instead of continuing to boot to the Verizon Wireless screen and then into the phone, it gets stuck at a black screen. I have tried waiting for hours and nothing at all happens, also I can no longer seem to boot into fastboot mode or in other words the Powered by Android screen with the little 1 in the top left corner of the screen. Fastboot nor ADB recognizes the device when plugged into my computer, as neither list anything when ran. Please help, I don't want to have to pay and end up sending my phone into Verizon to be unbricked.

I have the same problem. I bought a new a Brigadier that was on 4.4.2. I rooted with Kingroot ran update and now my phone will not boot past Kyocera screen. It goes black with the back light on. Did factory wipe and still nothing. I am shocked that KK has killed yet another phone of mine. I very much dislike KK ROM. What did you find out?
Recently had issues with my G7 Power and it seems to be soft-bricked. I was using an app and the app in question usually has the occasional stutter but then things resume to normal a second later. This is what happened yet this time the phone froze and was completely unresponsive. I held the power button down, turned it off and back on and it seemed fine but for whatever reason it got stuck on the Verizon loading screen which never happens. Turned it off and on again and it got stuck on the Moto animation so I held the power button down again. The phone shut off and refused to turn on again.
Eventually I ended up getting into fast boot (initially tried getting into fast boot many times with no success, no idea why it suddenly worked that time) and reset the phone through there and it would still get stuck on the Verizon loading screen. Kept turning the phone off and returning it to fast boot to repeat the process which was probably a stupid mistake on my part as the phone proceeded to shut off like expected but this time I couldn't get into fast boot anymore at all, even when keeping it on the charger that came with the phone.
LMSA was looking like the perfect solution but my PC isn't recognizing the phone as a drive so I don't think any sort of software made for instances like this are going to work unless there's something I'm doing wrong here. I can't get into the phone to enable USB debugging either.
Any recommendations as to what I should do? It's looking like sending it back to get it fixed is my only option here. Never had any issues with the phone until now.
Re-flash Stock ROM.
Code:
adb devices
adb reboot sideload
adb sideload <STOCK-ROM-ZIP>

My PC won't recognize the phone at all, would this still work? Would it also completely wipe the device's memory?
