I have a rooted and bootloader-unlocked Inspire 4G. A few months ago, I had been using the MoKee 4.2.2 ROM for some time, and one day, my phone's screen simply froze. I thought I shouldn't be worried about it, so I pulled the battery off, slapped it back in and tried turning on the phone again. It never got past the MoKee loading screen. I tried charging it, leaving it to boot for hours but nothing.
Next, I tried rebooting into CWMrecovery to try different stable backups I had from some time before that happened. The backups restored successfully, but again, the phone stayed stuck in the loading screen. I tried the same with 4EXT Touch Recovery and wiping all the data before the backup, but still nothing worked.
Since I was too busy at the time to install a new ROM and flash a new boot image, I decided to put the phone away and use my backup Galaxy Ace. Today, a few months after that happened, I tried to boot the phone into bootloader and I can't even achieve that. Holding the volume down rocket and power buttons, the phone still boots normally and stays stuck on the loading screen.
What weirds me out the most is that this was all random--I did not drop the phone or did things to it that could break it.
I feel if I could get into recovery I'd be able to do something else about it.
Any ideas?
Me too
Weird, mine just did the same thing today. Crashed, had to pull battery, now stuck at Mokee. Tried clearing DC, cache, factory reset. No luck.
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 ?
Hi guys, so recently I bought a Galaxy S6 Verizon off of eBay. I got it for fairly cheap because it was stuck in a boot loop. I usually have no problem fixing stuff like this, but this time is different. So the first thing I tried when I got the phone was to do a reset and cache wipe from recovery. I rebooted the phone and it showed a screen that said "Android is starting, optimizing app 9 out of 31." when it got to 21 the phone rebooted and went back to 9. It did this several times before I attempted to wipe/reset again. I then downloaded the tar file G920VVRU4CPH1 and flashed it in Odin. I did a manual reset before the phone booted, and it is doing the same thing again. reboots to a green screen where it tries to optimize apps, stays there for about 20 seconds, and reboots over and over again in the same cycle. I have tried all other stock marshmallow roms that i can find, Odin won't flash older ones, (assuming its not letting me downgrade). Also another weird thing, every time I flash, the blue update screen goes to 32%, stops, erases, and reboots. Phone is on 6.0.1 version MMB29K.G920VVRU4CPH1 as seen in recovery. Any help would be gladly appreciated. Thank you!
I am having a similar problem with loading new rom. The farthest it gets is 32%. Sometimes it doesn't get even that far.
I ended up just buying a trashed s6 and swapping the motherboards. Only way I could fix it
Hey Samsung users.
my case is a bit weird.
i bought my s8 running nougat used it for 2 days and it was all good , so i received the Oreo update and updated it using the over the air when I received connected to wifi.
my phone started to reboot randomly even for 30 times per day , i tried several things like wiping cashe and the only solution that reduced the problem was uninstalling my installed apps. basically normal apps like facebook , whatsapp , spotify ,and even stock apps like calculator and music player.
today as usual I woke up picked up my phone and it started rebooting so i uninstalled some apps but it kept rebooting.
sometimes it reboots and get stuck at GALAXAY s8 boot screen [ not samsung flickering screen ] and all i had to do to overcome the boot loop is pressing and holding volume down and power button.
but one time it got stuck and boot looped once and for all. I tried to press volume down and power button to make it reboot again and overcome the bootloop but it rebooted and got stuck at the bootloop.
I tried to access recovery but i couldn't access it.
I can access download mode only.
my phone switches on itself when it is plugged in to charge , i can't turn it off completely to charge it while off.
I reflashed stock firmware and it succeeded using odin but the bootloop is still there.
please help me with my problem.
any slight help or idea would be a life saver for me.
sincerely,
Zack.
Hello
I am very frequent with root and roms etc. but i am facing a big problerm with my s7.
i had already rooted it long back and had twrp, worked great for a year.
but suddenly around a month back it started restarting on its own. and at times it would get stuck at the Samsung logo.
i didnt care that much but then it kept on increasing and happened very frequently. the system will boot up and within 5 seconds it will get frozen, and no its not an app coz it happened in Safe Mode also,
also the screen would become hazy, like the tv does when there is no chane, become greyish.
also when i boot in twrp it would get frozen, like during wiping cache or installing, it will just get frozen in between
i tried upgrading to oreo somehow it started but when i restarted it wont start up. it would be stuck at s7 logo.
TWRP still getting frozen also i have tried other versions, no luck,
then i installed resurection rom for s7, it booted up, was working fine but then when i restarted it would not boot up system.
thats the problem i am facing now,
i tried down upgrading to Nougat but now it will say updating system and then erasing, and then it would get stuck wont boot up the system. it will keep restarting and then get frozen.
Literally spent more than 24 hours on this and no luck
please help
