Hey there,
I'm stuck with the nexus 4 at the "X" loading screen. I've been trying all things I can to fix it: flash an older OS (back to 4.2.2), and just now I did the guide described here to so call "unbrick" the phone.
During the last guide everything went succesfully - however I still am stuck at the "X". There are two remarkable things though:
-During the guide you flash a developer image (that you can't use as you don't have the password)
-Just when the batteries drop dead (and it shows "powering off") I actually see the correct screen (welcome, first time settings etc).
How can I fix it? LG doesn't want to do anything as it is now "rooted" apparently..

Starting to get frustrated. When I got the Galaxy Tab 10.1 from I/O it originally had a severe back-light bleed which I described in this thread:
http://forum.xda-developers.com/showthread.php?t=1076349
Samsung Level 3 Support was quite awesome and sent out a replacement. The back-light bleed is still somewhat present, but not nearly as bad. So a few weeks have passed and ran into another major issue: it entered a infinite reboot loop.
I have only about 10 apps or so installed from the "Featured" section in the Android Market. I have never bothered rooting this, dealing with custom ROMs, or anything of that sort.
I just get white text on the display with a black background which says:
Entering upload mode...
Upload_Cause: undefined
Holding down the power button again just takes the tablet into a infinite reboot loop. I see the start up animation and the Samsung logo, then it repeats over and over.
Samsung just set up a RMA to get this re-flashed. Anyone else have this issue? Is there an easy solution to solve this without having to send it back in?
Thanks!
And I have the same issue here any help guys!!
same issue, looking for a solution
exact same issue. Any solution or suggestions?
I have the I/O tab, unrooted. I had the exact same issue. Just overnight the tablet went bonkers. The tablet would continually load the Samsung Splash screen over and over. If I tried to wipe the table, I got Entering upload mode, Upload undefined error. I sent my tab in after pulling my hair out trying to get a fix. I couldn't even work on the tablet because it would not hold a battery charge. Some process was constantly draining the battery. I personally wish thye would just give me a production tablet. I'm afraid that when I get it back, the problem will re-occur.
I have the regular retail version. I've had it for about 9 days and have used it every single day. Last night I downloaded 2 movies onto it and everything was fine. Today it would not power on one bit! I charge it over night so the battery shouldn't have drained. Anyone experience this before???
Nevermind: Fixed my problem by doing the following!
Press and hold the on button.
At the same time, keep a finger on the screen.
Keep watching and you might see a slight change of color on the screen.
Hold it down for 15 seconds or more. Be patient.
IO Boot Loop
same issue for me - working great then all of a sudden it froze, i rebooted and got stuck in boot loop
tried:
ODIN flash recovery - still boot loop
NVFLASH recovery - installed but cannot get into recovery mode -only fastboot and ODIN
FASTBOOT mode - adb not seeing device even though ODIN sees it - installed PDANet to get Android USB driver - still not seeing device
any thoughts?
sINCE THE release of touchwiz roms, a bootloader file is included as bootloader.tar.md5. Flashing this (repartition unselected in odin) gives you retail like options in boot screen with keys combo viz. recovery and odin. Try extracting and flashing the bootloader file from stock roms I uploaded.
COUNT:5 repetitions of this solution!Gladly, though one should bother to search!Or check the similar threads suggested when starting a thread.
thanks mughalgxt - where might this bootloader.tar.md5 be downloaded? To clarify did you mean by the extracting comment below that the bootloader you provided already contains this update?
also as for repetition - since i am still looking for a solution and some of those thread have the same symptoms (boot loop) but different solution methods (nvflash, odin, fastboot) - i thought it might make sense to add my description to my issue to apply additional context/clues

I had uploaded a stock euro rom(check under arabic rom topic in development section), courtesy of samfirmware.com. You can extract the bootloader.tar.md5 file from the rom rar file. This will help you to force key into recovery as the boot options will be replaced from fastboot to recovery. Just make sure you don't select repartition while flashing with odin as that'd leave you bootloader locked!
Hope this clears up! Once in recovery, the options are endless!

WORKED like a charm!
As a previous user posted here http://forum.xda-developers.com/showthread.php?t=1899024&page=172 I'm also having the same problem as he where the geen circle is revolving around the android in a loop. It only once completed the boot process but I only had a black screen with no choices to make. Since then, it only loops with the circle around the android. The tablet will not boot into recovery using all the options I've read on the forum and elsewhere. I used the JROMFlasher as noted [I usually use the Nexus 7 Toolkit]. Went through all the steps as indicated and loaded the SmoothROM. It only loops and the author really didn't answer the poster's question on how to get out of the loop. He just sadi to use the JROMFlasher. Trying to boot into Fastboot with the JROMFlasher only asks me if the device is turned on/plugged in. Pressing the Boot into Recovery tells me the same. I'm able to boot into the screen to choose power off/recovery/and restart bootloader. Only the restart bootloader and power off works, so I've powered off for the time being until I'm able to get the tablet "unbricked." I've previously used various ROMs on this site without incident using both JROMFlasher but mostly the Nexus Toolkit, except for this one incident where I've run into problems. It looks as if this problem is permanent on my tablet.
Well I managed to actually connect to the device and I can see the folders in Windows 7, but they're all empty, no system files, nothing, only the SmoothROM zip file I managed to get on the device yesterday befoe I began having problems. JROMFlasher cannot see the device, and niether can the Nexus 7 Tookit, so I guess I have a completely POS on my hands as of this minute. The looping is still there on the animation screen, but that's all I see. Time to power off this POS and send it to the trash. Don't think I'll be rooting any more devices.
Hey guys,
Coming from Nexus 4, I'm fairly new to the G2 forums. Last week I rooted my D802 and flashed the OptimusRS Kitkat rom (V3.5) and played around with some tweaks to change its framework. I installed Xposed (2.5 beta) and a few modules (Gravity Box, G2 Tweakbox) to hide the navbar and some other cosmetical stuff. I noticed this beta release of Xposed was still a little buggy here and there, so I removed it manually (through the app itself and rebooted...
...and then I got the infinite boot loop.
Since I removed Xposed manually, my G2 is stuck at the LG logo, I can't get into recovery, I tried a hard reset (by pushing the power button three times in the white screen), but after that, the screen remains blackish (there is some light though, so the phone is 'on').
I tried several guides to restore the stock firmware, but my Windows XP laptop won't recognize my device. The LG R&D software says my phone is disconnected, so restoring gets stuck at 15%. When I try to put my phone in download mode, I only see the little blue sign 'download mode', but no other options.
I'm absolutely out of options. I'm quite experienced with flashing roms, but never got myself in so much trouble before. I almost threw my G2 (which I really, really love) out of the window because of this.
Thanks in advance.
although this is not the same sequence of events, it describes a similar condition to you - can't boot, can't get into recovery, can't get into download mode

I already gave that one a go, but ultimately, that method gave me a no go as well. But I'll try one more time and meticulously follow all the details. Thanks for your response! :good:
LG G2-D802 Unbrick Device by g0dsend313 (mlm1102003)
PHEW!
The method in this thread finally did the job. I had to put my phone a mode I did not read about before: after hard resetting, I got a blackish screen, had to plug in my usb cable and let ubuntu finish its sequence. After that, I could reach twrp to do its magic. :victory:
I've been messing around with my phone, trying to flash CWM and CyanogenMod (to no avail), and yesterday something happened. I woke up, my phone was dead so I started charging it. It booted into the Stock OS (the one that ships with the G2--build D20010o I think). Shortly after, a message appeared on the screen about an update the phone was going to install (I'm assuming one that AT&T was pushing to my phone), and shortly after it powered down on its own. I have not been able to get it to boot into the OS since.
Before all of this happened, I rooted the phone with IORoot, tried to flash CWM (I think successfully), but was not able to install CyanogenMod, so I flashed an earlier build of the stock OS (D20010o), rooted it again (I'm not sure that I had to--I think it stated that my phone was already rooted), tried to flash CWM again (unsuccessfully this time), and I gave up. Then this problem occurred.
Every time I try to power on the phone, the LG logo flashes, and the screen stays on, but it's black. If I try to do a factory reset via the hardware buttons, I am able to see that screen, but as soon as I follow the instructions of pressing the power button twice, it says that it's initializing the reset, but then the phone's screen goes black again--not sure if the screen is on or off, though. The LED light is also not on during any of this.
I'm unsure what to do. I've had the phone for about 6 months, but I had not owned an Android before that--iPhone user for 3 years. I obviously did not do enough research or ask enough questions, but I would like my phone to be in a usable state. I would greatly appreciate any help that anyone can give me!
NEVER take an OTA with a recovery.
Use the lg flash tool to go back to stock

Sorry, should have also mentioned that I can't boot into Download Mode. I'm assuming there's no .kdz file for AT&T, and the other method in that link requires Download Mode. :/
Hi.
A friend of mine bought a used Nexus 4 a few months ago. It came with open bootloader and TWRP installed, worked just fine. A few days ago a strange thing started to happen, when he locked the screen, the phone wouldn't wake up from it, only after a restart it would work until he locked the screen again. It didn't work even after several factory resets. He said there were a few times when the screen flashed and it started to work again, but only for a limited time.
So he gave it to me to install a new rom or do something with it. I'm not an expert or anything like that, I had installed a few roms on my previous phones and that's it.
First i tried to boot into TWRP, but there was only a black screen, so I decided to flash the stock recovery with the Nexus Root Toolkit I've found on XDA. When adb rebooted into TWRP and tried to push the new recovery onto the device it encountered a problem and advised that i should change usb ports. When i changed to a new usb, the screen flashed quickly for less than a sec and it gone black, but i was able to see that there was some kind of safety check in twrp which i needed to unlock to be able to push the new recovery onto the phone, but I couldn't unlock it because the whole screen was black and it didn't respond.
So my question is that is it some kind of hardware failure, or can it be done without taking apart the phone?
I've also made a few videos about it:
It's about the flashing screen in the recovery(after that part there is nothing, i wanted to film it in one piece but it started updating apps and i stopped recording):

(I just registered and I can't post links until 10 posts.... I hope I don't violate the rules too much with this....)
On this first you can see a new thing that never happened before: the screen flashes in dark colors and slowly fades to black. After I reboot the previously described things happen:

Thank you for any help!
