Hi
I have a LG G2 running CM12 which I just tried to encrypt (about to sell it). For some reason though the encryption failed, which I've never seen before. I had full battery and the charger connected.
Anyway, it presented me with the only option of resetting the phone. I clicked yes and now I'm in some sort of bootloop. The "teamwin"-logo for TWRP is presented on the screen for a couple of seconds, before it goes black for one second and then back to the teamwin-logo etc.
I don't care about the data, but how can I fix the phone back to CM12? Please help me!
See Edited post below
I managed to get it back to stock with LG Flashtool, rooted it and installed TWRP using AutoRec. Booted in recovery mode and got an error:
"assert failed: run_program("/system/bin/loki.sh") == 0
E:Error executing updater binary in zip '/usb_otg/cm12-20150612-NIGHTLY-d802.zip
Error flashing zip
After this I can't boot into the phone, it says "Security error" under the LG logo. After this happened I went through the same process with LG Flashtool and tried again, unfortunately with the exact same result. I've tried different ROMs aswell. Can someone please help me sort this out?
After hours of trying I finally sorted it out. If anyone runs into the same problem this helped me:
- Flash a stock KitKat-ROM using LG Flashtool
- Root using LG OneClickRoot
- Download AutoRec for Kitkat-apk from the web (not available in Play Store anymore)
- Run AutoRec for Kitkat and let it install TWRP
- Download and flash some CM11-ROM
- Check to see that all seems fine
- Download and flash the CM12-ROM you want + gapps
- Hopefully you'll run CM12 just fine again
That did it for me, not sure that every step is essential but might as well try it.
Okay... My phone was working just fine, and I thought it was just fine so I didn't think about it when I performed a factory reset through the IU. I shouldn't have done that...
The problems came back, first the twrp-bootloop so I tried to flash the kdz again. That failed and after that I no longer can access download mode. What happens when I try to is that the LG logo shows as it should, but then instead of going into download mode it takes a little longer, and then the phone opens up like 20 drive letters on my computer. One of them contains files in a folder called "image".
Am I 100% ****ed? I would really appreciate it if someone could help me out with this one!

Hello guys.
I have an LG L5 (E610) that is having a very strange behavior.
It started by throwing a lot of ANR with different applications (Google Play Store, Play Services, Facebook, and others).
So, seeing this, I decided to do a factory reset. After reboot, what is my surprise that I see everything as I had before. All the applications, all the data, everything.
With this, I tried almost everything at the moment. And by saying that, I mean:
- Tried to follow the key combination for the recovery, it goes to recovery, I see the Android and some progress bar moving, but after the reboot, the system remains with no change;
- When on the system, I uninstall applications, they seem to be uninstalled, but after a reboot all the applications are back.
- Tried to root the phone with more than one process, no success. I cannot install any application. Not via play store, not via adb install, there is no way;
- Tried to flash a recovery img, to try to clean cache partition from there, no luck. From Fastboot it says everything went well, but when I reboot, everything is the same;
- In fastboot, I tried to erase cache and userdate partitions, no luck. When I try, i have a message saying "FAILED (status read failed (Too many links))". This happens with all the partitions. I even tried to erase the system partition, and I have the same response. Strange thing is that after this error, the phone reboots and goes directly to the system;
- Tried with KDZ images and tools to install different versions, I receive errors during the deployment and at the end the phone reboots. Again, the same system is installed as before. No changes.
As of now, I was trying to understand if there is any problem with the internal flash system. Maybe it is corrupted and is causing all these issues.
The thing is, as the phone is not rooted, I cannot launch a e2fsck to the maybe faulty mmcblk0pXX
The phone has a stock ROM based on Android 4.0.3 (build IML74K / LG-E610-V10e-JUN-30-2012)
I am out of ideas, I've looked around here at XDA, Google and I have no other ideas to try.
Does anyone have another suggestion?
Is there something else I can do to try to make the phone live again?
Any help someone can provide will be very much appreciated..
Now this is what I call a coincidence.
About 2 years ago, a friend of mine asked me for help with her E610. Almost all actions were giving us ANRs. Whatever you do, i.e. unsinstall, install, change, delete... after reboot/reset were all there, even notifications! Tried KDZ updater, and, while the update was OK without signs of errors or so, after reboot - nothing, everything was like before. After trying to find a solutions by hundreds of ways, with adb and fastboot commands (all partitions&folders were locked, no read, no write, and you can't see any file, tried root to no avail), L5 got bricked. She already got a new phone and this LG was laying there without any use.
Three days ago I decided to try again, with no hope tbh No screen, no vibration, nothing, apparently dead. But, I could install Qualcomm drivers and my Windows can see it in download mode. I think that the only way is to flash the phone with LGFlashTool and using COM port. I already extracted *.dz from *.kdz but I need the dll for FlashTool. Found 2 or 3 webs with this dll, but you need a 100 bucks subscription :crying: If anyone can upload that dll I'd be very happy to try to flash this phone I'm really big n00b in this, just a plain phone user, nothing more, so don't blame me if I said something wrong
Many thanks in advance.

Hello! Same problem...
My L5 is making me crazy... It has CyanogenMod 10 nighlty. A friend of mine was using it and he tried to install the GAPPS after he did a factory reset. I have no idea what guide he used but it got soft bricked... It's constantly showing a "stopped working" message and after a while reboots by itself.
I tried to do a factory reset but it always returns to the same point, same apps installed, everything like the reset never happened. I even used CWM to reset it and it allways goes back to the same recovery point.
After a while I decided to flash a stock room but here's the problem: I can't get into emergency mode.
After reading ALL post about it I found that there's at least three ways of entering EM, (1) down VOL and plug in usb cable without battery; (2) down+up VOL and plug in usb; (3) down+up VOL + power botton.
Conclusions:
(1) - gives me a screen full of code like a command line
(2) - White screen
(3) - White screen
I've read ALL the unbrinking post on the internet, including xda, and none of them helped.
The KDZ Updater never recognizes the phone. I installed all the drivers but everytime I plug in the phone it installes the same LGE MTP drive...
Can anyone help, please?!
How to enter Emergency mode? How to flash another rom?
Hello everyone.
I have a D802 LG G2 16GB version.
I had on my D802 a BlissPop rom version 5.1 and it was frequently rebooting and sometimes when charging screen wont turn on and after rebooting it will say optimising apps.
I downloaded the latest Cyanogenmod rom for it and installed it from recovery.
The installation went quick and no errors, I then rebooted it.
It showed the LG logo for a second then only the back lighting was on.
I tried connecting it to the pc and it showed 12 drives all empty and with errors except one that had a folder called image.
It wasn't useful, so I tried the emergency mode and it worked - the PC detected LG and installed drivers althrough the memory is not detected.
At the device manager it detects LGE AndroindNet USB Serial Port and on the screen of the phone it says Firmware Update 0% and in small B60 ROOTED.
I will really appreciate any help regarding this, ofcourse I would like to find a way to fix it and get it back running if its possible?
Thank you!
EDIT:
I guess a possible solution is flashing a KDZ, but I'm not sure what KDZ I need for this. I have another identical G2 phone,how can I check using it what KDZ I need for it?(Which variant etc)
Update: Because of the problems with booting I automaticlly assumed that recovery mode is not an option but.. it works and I sucseesfully entered it. (!!)
I downloaded this rom http://forum.xda-developers.com/lg-g2/development-d802/rom-cyanogenmod-13-0-t3250514 (different from the one I installed before)
Then I wiped factory reset, dalvik cache and installed it, again installation went smooth.
After I hit reboot same problem, LG logo shows up for a second (quicker than usual, normal working LG) and then black screen with backlighting on.

have you tried hybrid bootstacks? install reboot recovery to recovery... flash rom and gapps ..?
if not use TOT methos.. or kdz. am not sure wich one ...
Problem fixed, the solution for me (It might be different for you if you're facing similar problem) was to download kdz and lg flash tool and reflash it to the original stock.
Hi,
I'm opening a thread because I just couldn't find any way to unbrick my device. In the past I used the FlashTool2014 to go back to the stock LP KDZ for my device.
I was in the stock rom when I decided to mess with the build.prop and then went back to the stock backup. When I restarted the phone it showed the LG logo, screen went black and never booted android. I could access the stock recovery but the Factory Reset won't work.
Then I decided to go to download mode, it connects and the PC detects it as an MTP device. I open the FlashTool2014 and it detects the device OK. When the LGUserCSTool opens it says the Upgrade stopped due to an error and the device stays on 0% and shows USER B70 in the console. I can press Retry, turn off the phone and reconnect in Download mode but the LGCSTool just wont push the firmware.
I suspected I had a driver issue so I tried using a clean win8 install I have for this purposes without success. I cant flash with the TOT method since the other LG Flash Tool wont detect the device in download mode when connected to the pc. This is really weird.
Any ideas ?
Thanks in advance.
EDIT: Solved with another tot file (almost lost all hope), took me 20+ hours to download it, I'll better make a backup of this files on the cloud. Still having problems with STOCK firmwares but could install TWRP and get CM13 which doesn't give any problems.

I had a very similar problem with it getting stuck at the logo after pushing supersu to the phone. I followed Supersport every single step of the way in his video. I think his links are the only valid ones online now, so just download them and reflash your phone. If your G2 is anything like mine, drivers will never appear to be installed correctly and it never restarts, only shuts down.
His method is:
1) Download and install LG drivers on PC
2) Download and install the flash tool and patch it
3) Download and load the .tot and .dll files into the flash tool
4) Enter download mode on G2 by holding volume up while connecting USB
5) Switch G2 Com port to 41 in device manager
6) Once Flash tool shows that all ports are ready, power down G2 and disconnect
7) Hold volume up and reconnect to get back into download mode
8) LG Flash tool starts flashing
9) Complete
Note: If your G2 was screwed up as bad as mine, it'll say failed but all the main system files will load to the device before it restarts and it'll even shut itself off while doing it's installation on first reboot. Mine somehow was still revived from this state with his method.
Hello guys!
Unfortunately I have managed to full brick my phone which has worked without any issues for more then 3 years.
My story:
1. Phone started to have random restarts, basicaly, when phone lagged little bit - it restarted phone.
2. When I did manual restart, I got into bootloop and could not get out
3. With a heavy heart I did a factory reset. - Problem with random restarts ontinued together with random bootloops.
4. Did maybe 5 more factory resets, nothing happened.
5. Found a tutorial to flash new firmware.I was on 5.0.2 D802 30d so I used same. (PC suite could not find my phone and LG support tool always freezed on SW install)
6. I used LG Flash tool with normal flash. - used *.kdz which I have downloaded via LG support tool - checked size with dl from source from xda and they were same so i used it.)
7. All success, but device keep restarting - i think no bootloop anymore.
8. I did full flash again with LG flash tool so have a clean install and hopefully fix everything.
9. Suddenly mid-install my phone auto-disconnected from laptop and even with Retry attemps I wasnt able to get it running again. Then my phone restarted itself and that was it.
Now I cannot go to recovery mode, I cannot go to Download mode, all I see is black screen (turns some light on little bit underneath but no data visible).
Also when connect to my Windows 10 laptop multiple discs trying to load and trying to format disk. (one of them contains folder image with some files inside).
I dont have root, I dont have any other tools installed on my phone, just a normal user.
I tried to download adb but i dont understand it much, and also it cannot find my device.
Is there any way how to still fix my phone or is it completely lost
If so, I please you for a dummies step-by-step list .
Thank you so much in advance. :crying:
So good news,
I managed to load img back with dd application.
My Download mode together with factory reset is working.
I have tried to flash it with LGUP and even with some accused usb disconnections I probably managed to flash new lollipop to my phone.
Now it is optimalizing apps to load android correctly. Only issue I have is low battery, it always drains it too quickly so it cannot load properly.
Any idea how to charge the battery? Every time I connect phone with usb cable it starts up into boot, possible bootloop (cannot say if it is because of low battery or real bootloop)
Thanks
Dude try to install crdroid 7.1.2 nougat rom of d802 this will fix your battery problem
root it and install TWRP with srktools 2.0
this is best way to root G2 5.0.1 lolipop
you can also use LG One Click Root to obtain root then don't update su binary and install Autorec of you model to get twrp
