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.
My phone is rooted with stock rom. The only changes are listed below
Froze bloat that was safe
changed bootanimation to stock samsung
replaced some apps with inverted versions of themselves (ex. google +, stock messaging)
Here goes:
I was using navigation and I noticed that my phone was off after I had finished. Nothing worked at all, I could not boot into recovery or download. I connected the phone to a charger and red led flashes and an empty battery appears. The battery was full. I could reboot the phone while on the charger, but it would shut off as soon as it got to the homescreen. While off, If I pressed the home button, the green battery would appear as if it were charging. From here I could boot into recovery and download mode. The phone will only boot into these modes while connected to the charger. Here is where it went bad. I attempted to restore a backup while the phone was on the car charger and my car charger got pulled out in the middle of a restore. No charger meant that the phone shut off mid restore. Now, when I plug in the phone, the red led appears and the empty battery with a circle inside appears and then goes away. This repeats itself over and over and the phone buzzes when the empty battery reappears. I can still boot into download mode but not recovery. If I try to flash the stock samsung rom via odin, it says that it passes, however upon automatic reboot the samsung appears and nothing else. After the samsung appears the phone just continues to buzz every 5 seconds or so as if it is trying to do something. Could it be a bootloop? I have done a ton of searching here and now I am resorting to help! Your time is appreciated and beers on me if you can help me get my phone back to normal.
Put your phone into download mode and let it sit on the charger for 30 minutes. After pull and reinsert your battery and then try to power on your phone without your charger. Then proceed to charge your phone to full since it powered on.

This did not work but thank you for the suggestion. From what I have gathered, as long as I can get into recovery then I should be able to get everything back to normal. Anyone?

if you can get into download mode, you can use odin to fix everything.
you might have to do a complete wipe but it is what it is

I tried this already. My problem is that after I flash the first bootchain, the second bootchain will not flash. I gets stuck at the setup in odin. I see there is an option to disconnect the phone and exit odin and reconnect the phone without leaving download mode if this happens. My problem is that if I disconnect the phone from the computer or from the charger it shuts off automatically. I tried these steps the best that I could and when I click nand erase and it reboots, then all it does is buzz every few seconds. I then shut it off and do the data and cache wipe and reboot. It reboots and appears to be the stock rom asking me for language and activation after, but the phone shuts off almost immediately and reboots to a blank battery with a circle in the middle. This is after I have had the phone on the charger for a long time. This happened out of the blue after I was using navigation. This problem did not arise from changing something in the system or from flashing a rom or kernel or anything of the sort. No one has seen this issue with the blank battery? I saw someone mention in android forums but the resolution was that they returned it and got a refurb.
I was having terrible GPS reception and I tried the antenna fix- sliding a tiny peace of thick paper under the antenna connectors:

After powering up the phone booted once, then rebooted after couple of seconds and has been bootlooping on Google logo since.
- Takes much more time than normally to power on, then falls into Google logo bootloop,
- Cannot go into bootloader, power + vol buttond doesn't do a thing,
- If I hold vol up + vol down while bootlooping it powers off,
- Plugging in doesn't change anything, no charging indicator when powered off.
Is there anything I can do ?
Did I kill my phone ? If so, how ? What could I have damaged by simply prying the cover open ?
Are all the connections secure?
I checked all the connectors, they're ok.
After a day or so the phone got back to the living- I was able to boot and play around for a while.
Then I tried to update (I got the Lolipop OTA), which failed...
Downloaded the factory image and the flash attempt always gets stuck at " sending 'system'"...
Bootloader, radio, recovery, boot, everything gets flashed, then it gets stuck at flashing "system".
Any ideas ?
EDIT:
Flashed 4.4.4 in NRT without any problems, boots normally, still cannot flash Lolipop ...

Might need to wait for 5.1
5.0 is buggy
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 ?
Hello,
It all happened like 2h ago when charging my phone (was at about 96%).
I just tried to open a Snap and my screen glitched, phone turned off itself after few seconds.
I could turn it on again only to see the same glitchy screen after one minute after turning on.
Now when I try to turn on my phone I can see the Poco logo and then a white screen with blue dots in a vertical
line going through the center of the screen.
I updated MIUI like a week ago, live in EU (MIUI was probably Global I'm not sure, I didn't change anything).
Bootloader is not unlocked, custom recovery is not installed.
USB Debugging is turned on.
Here is imgur with few photos of how it looks now:
https://imgur.com/a/lXsIm4t
Please help.. I've read that I need to give my phone to a service and they need to replace the motherboard.
I really don't want to lose my data.
I never read about that glitch in Poco phones before and I didn't back up my data.
I really need to get my photos of the phone (I really hope USB debugging helps here).
I also have Google Authenticator on this phone.. no idea if it's possible to get the keys back..
Maybe I could try tools from the index thread but I'm really scared I will make things worse, I need help with that.
That's not actually a brick ,it's jus a screen bug/error in MIUI , I had this white screen but only when I installed MIUI after a custom room ,but it solved very easy by turning phone off/on , but what you have is different ,I suggest you to enter recovery by pressing power button+volume up and factory reset the phone ,but first try entering safe mode by rebooting the phone and when the Poco logo appears, press volume down until safe logo appears, if your phone boots in safe mode you can recover your stuff , if not try factory resting to get the phone back.
try flashing the stock rom again using miflashtool.

You should flash MIUI again with Mi Flash Tool , if it still happens you should flash a custom rom,if you get the same result go to a repair center.
just happend this today to me aswell, same problem with white screen and blue dots in the middle, i had it working for a bit like 3 times after restarting and restarting it for hours, it works for some time and randomly goes blank, safemode doesn't work the problem persists in recovery mode too but it works for the most time, i've never had a custom rom everything is stock and im on miui 13.0.1, the phone does not respond to charging it when off and you have to hold the power button for a long time to turn it on
I recommend to flash stock rom through fastboot mode.

That's indicates your mainboard is broken. claim your warranty for mainboard replacement or new phone replacement(in some region)
i got it working again after messing with plugging the charger in and out while powering it on, it booted and i reinstalled the latest update again from the settings and its been working for 6 hours now, no problem so far.
its a softbrick, in the message above i said that fastboot did not work and i was wrong, but you need to have the bootloader unlocked if you want to try the stock rom flash method

I don't think its a softbrick you should get it inspected at any Xiaomi Repair Center.
Same has happened with my POCO X3 PRO. However, after few restarts the phone is now not re-starting after long press boot button. Help.

try charging it overnight and retry even if it does not respond to charging, i did that too when mine stopped powering on although it only charged around 41%

i know it might not be a softbrick but the charger case worked for me it might be a coincidence too because it is random most of the time it boots up randomly after restarting several times, when it does it can work for as little as some minutes or a couple of hours, to me it seemed like the rom got corrupted or something, im not an expert.
