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.
WHILE SWITCHING TO ART BOOT SCREEN STUCK IN"ANDROID IS UPGRADINGPTIMISING APPS"
Hello,this is Jacques,and i need serious help for my LG Optimus L70 ll .
I had switched dalvik mode to ART mode on my lg running kitkat 4.4.2 it immediately shut down and restarted itself and on boot screen saying "Android Upgradingptimising apps 4 of 162" and then i left it thinking process would finish in 10 to 20 min. but after 30 min i came back and saw my phone is just restarting itself many no of times ,it got heated up too much(never had any heating problem but recently). Then i thought about soft resetting it and pressed both volume (up+down ) and power button for 8+ seconds ,then my phone did restart but again it came to boot screen saying the same thing as above but this time"Android Upgradingptimising apps 31 of 62" after that it came to next boot screen saying"Android Upgrading:Starting apps" but it continued for 2 hours and my phone was also getting heated up so i thought about charging it but when i did so the phone didn't recognize anything after waiting for an hour suddenly it showed that t had 0% battery and switched off itself after that i haven't charged it till now and being frustated have firmly changed my mind to go back to dalvik mode.
So, here are the questions :
1)How do i do it?? because my phone is stuck at boot screen so it won't start and i can't change it to dalvik mode through developer options !!
2)I have read through this link that we can set it back to dalvik through my computer with adb shell technique but there it said that my phone should be rooted so it is but i didn't know how to create files in my computer in 3rd and 4 th step. but does it reqiure usb debugging options enabled as my phone is switched off for now and what do i do next??
http://forum.xda-developers.com/android/development/guide-manual-change-dalvik-vm-to-art-t2823715
Though in this link it says how to go from dalvik to art but in the last it states how to revert but does it need a switched on or off phone??
LAST question )Will it work?
Any suggestions regarding this will be considered Thankful and Helpful.Please help me fast i am in emergency :crying::crying:

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.

Hey all,
I was hoping that someone here could please offer some advice that I'm having with my tablet. Using the Note 10.1 GT-N8000
So at the weekend I had an issue where the tablet just kept freezing on me, screen wouldn't time out, clock wouldn't update etc. So after several reboots I figured the only thing for it would be to wipe it and start again. So after getting to recovery mode I wipe the cache and then eventually did the full wipe thing. Booted up after that as expected like brand new so I did the whole reinstalling my apps and what not thinking everything was a-ok. So I came back to it a lil later and it's off (so i think the batts just died on me) plug it in and put it on charge and boot up and it won't get past the 'Galaxy Note 10.1' screen and just cycles in a constant loop. I tried to then go to recovery mode again and whilst the holding up and power gets me to the screen I would first see the android logo with the energy belly (no menu options appear) and it would instantly switch to an android logo on it's back with a red exclamation mark icon atop it, before returning to the boot loop. I've tried to get into Odin mode which i can successfully do.
I've looked at some threads here about similar issues but tbh with some terminology used I'm a bit unfamiliar with so was lost on them quite easy, my knowledge on these issues being rather basic.
If anyone could offer any assistance I would be most grateful
Thanks
Flash stock rom from sammobile viaOdin.

Last week I factory reset the tablet in the settings app (normally), it works fine before I factory reset, but after I did the factory reset, the tablet keeps on booting on the samsung logo then to a android with something working on his stomach then android robot with a exclaimation mark on its stomach. Its keep happening over and over again. At first I thought it was one of the procedure to reset, but then I keep doing it for an hour so I turned the device off. I tried to enter recovery mode, but I cant. The only mode I could get into is Download Mode. So I found this method using Odin to recover. But it wont work also. Tried all kind of Stock ROM still wont work. Ive tried one ROM that made the boot loop different, instead of loop with android stuff like before, it just stays on the samsung logo. I have a video to show you the problem that Ive been facing
***search "Samsung Galaxy Mega GT-I9200 reboot loop, no recovery menu" on youtube***
since I cant share link with you guys
In my case there is no "No Command" words at the screen.
Any suggestion on solving this?
