[HELP] Soft bricked smartphone - G2 Q&A, Help & Troubleshooting

Hi everyone,
For some stupid reason a reset the file system i now I'm stuck in the LG logo.
1. I can enter in download mode - in Device manager the PC recognized as LGE AndroidNet USB Serial Port (41)
2. I can enter in recovery mode (Cyanogenmod recovery, which is very based) - in Device manager the PC recognized as Android ADB Interface
So far, so good. BUT. I'tried to flash the phone with LG FlashTool 2014 and i'm stuck at 2%. Ok, i was tried the fix with FixedDownloadcmode.bat, but when nothing is uploading on the phone (which by ADB is recognized as sideload when i'm in recovery mode and apply the ADB connection). I tried to push by ADB but nothing is uploading - error: protocol.......
LGUP recognized my phone as unknown, so this method is not working now.
Via ADB i can't send even TWRP recovery, which is so much flexible than cyanogenmod recovery.
I will be thankful for any help from your side.
Thank you in advance!

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.

I forgot to add this but couldn't edit my post for some reason.

In TWRP is the zip signature verification checked? That happened to me and all I did was uncheck it

LG F320s Download mode not recognized by PC + Only boots to recovery

So I am hoping someone can help me here.
I was attempting to install Cloudy G3 (1.3) on my phone and did the following things from stock 4.4.2.
1. Root using ioroot (Success)
2. Installed CWM semi touch recovery (somehow the chinese one got installed rather than english)
3. Used an app to boot me into recovery as the manual method was not working for me.
4. The chinese recovery opened up (to my surprise) and so after reading translations, i pressed restart.
5. Phone now stuck on LG screen with flashing LED.
Progress:
I have figured out that I can get to the chinese recovery by holding Power + Volume up for 5 seconds. Weird because I though you were meant to hold volume down??
I then tried flashing Cloudy G3 form my SD card by using the normal process
-Wipe cache,data,dalvik
-Install KK baseband zip
-Install Cloudy rom zip (Aroma setup works and I can go through and select all the things i want and the rom does install)
-reboot after finished installing
Now the phone boots with lg logo, goes black, goes to lg logo again and then goes into recovery all by itself without me touching volume buttons.
I am trying to go back to stock but the computer won't recognise my phone in download mode
my download mode just stays on this screen.
Needing help with this please!
Maybe there is a solution without using my comupter?
I will play around with uninstalling/ re-installing drivers this weekend.
I have tried a windows 7 and 8 PC.
I have the same problem from exactly the same process. Have you had any progress?

Hi, thanks for your response. I have downloaded both files.I want to go with solution 2. However, I'm quite confused which file inside the zip on solution 2 I would need to replace with the file in solution one.

just extract file from first one and rename it same like file from fx22.zip
replace content fx22.zip with that modified file with winrar or 7zip (just simple drag n drop)
put on usb flashdisk drive using usb OTG or adb sideload and flash it
Sorry, but the file from Solution 1 (zip file) contain the following:
cygwin1.dll
dd
mmcblk0p2_sbl1
mmcblk0p5_aboot
mmcblk0p6_rpm
mmcblk0p8_tz
mmcblk0p15_recovery
recover_partition
Which one should I transfer to the file on solution 2?

[HELP] PC Recognized F320S in download mode as unknown device

Hi, you may all be so used to this, however, this is my first time. I rooted my LG G2 F320S and installed custom recovery (CWM). Well, I thought I followed the instructions to the letter. However, my phone is now stuck at the LG boot logo. Anyway, I am now just planning on going back to stock. However, after installing the LG drivers, my PC detects the phone (while in download mode) as unknown device. I don't know what to do. I tried to right-click the item in the device manager and update drivers, but window's can't find the appropriate drivers. I can't boot to recovery, but while in download mode, PC can't recognize the device? Anyone can help me out? It would be greatly appreciated. Thanks.
1. Uninstall LG drivers
2. If u have Windows 8, put it in mode which allows to install unsigned drivers, just to make sure (hold Shift and choose to reboot in this thingy on the right)
3. Plug it in with download mode and install THESE http://tool.xcdn.gdms.lge.com/dn/downloader.dev?fileKey=UW00120120425 drivers
Hi reas0n, thanks for your reply. I did follow your suggestion, however, it's still the same case.
Any help, guys?

Hello everyone !
I have big troubles with my Lg g2 d802.
Yesterday i want to intall crdroid 5.0 on my Lg g2 on Official 4.4.2, so i've:
Root my phone
Install CWM Manager
Set CWM Recovery
Reboot in recovery
Use ADB Mode
Use ADB on my PC to send crDroid zip by sideload
During sideload, after full download, there was an error assert failed. So installation failed, and i've decided to reboot my phone.
Problem is here, my phone boot, display LG Logo and after 5 seconds, Lg Logo with "security error" message, then stop alone and reboot again, and again.
I have tried following procedures :
Power off completely my phone and then Volume down+PWR to enter in recovery : FAIL
Volume Up and then put USB cable to enter download mode : FAIL
Connect with USB on Ubuntu to try to reset .img files : FAIL (Phone invisible on my pc, even not recognize)
So i cannot go to Recovery Mode, Download Mode and my phone isn't recognize on PC.
I don't have any other ideas and i am here to asking help .
Thxs for reading, and i pray for a miracle !

[SOLVED] [Q] [HELP] Stuck in Download MODE

My LG G2 d802 is stuck in the download mode and has no recovery. It happened when i flashed Miui 6 by gtbluesky after full wipe of data and system. Previously it was on cloudy 3.2 . After flashing the miui it wont boot and is in a bootloop on mi bootscreen. I tried but cannot boot into recovery seems like it doesnt have a recovery.
However, I can boot into download mode but it is not recognised in ADB nor Lg flash tool. I tried flashing kdz with the lg flash tool but it wont detect the device. I tried installing various drivers to the pc and also tried two different pc with windows 7. However, adb wont detect the device.
Regarding the drivers, the windows installs all the drivers but fails to install the LGE Androidnet usb modem drivers. If i manually try to install it from the lg drivers, it would keep installing and returns an error of timeout period expired.
So, i am stuck in the download mode with a bricked device.
If Someone could help me with this problem, i'll be much obliged. Thanks
SOLVED
[SOLVED] I downloaded the .tot file for my phone and extracted .dll from one of the .kdz & flashed it using the lg flash tool . It flashed good and now my g2 is up and running. :good:
