I posted this in the LG F60 thread and figured this would be the better place for it. I cannot get those last two drivers to install and my phone has zero information on it since my dumbass wiped it all before backing it up. Anyone have a clue? All I get to is the LG boot screen. I can also boot to TWRP recovery. No SD card though.

I am stuck in fastboot screen and no recovery. did you find any solution for that?

I had the %2 error issue after flashing Cloudyg2 3.1. When I tried to go back to stock flash tool stopped at %2 and no flashing was possible. Thanks God I had TWRP. My solution was to flash the flashable zip stock rom I downloaded from the below link. After installation I was able to use KDZ method again with no error.

Hi turquoise.ht,
I have same problem here. My lg g2 d802 currently running on cloudyg2 3.1. When I tried to go back using flash tool it also stopped at 2% and the log "ERROR REASON: LAF_ERROR_INVALID_INPUT_FILE". I tried with two different computer, the result is same.

Is it going to work if I flash 30d flashable zip? I have TWRP installed on my d802.
Sorry bad english :)

Uhh well, I bricked my phone trying to install some mod and well, I used the LG Mobile Support Tool once and I restored my phone but now I can't.

I can go to download mode as well as TWRP, but the LG Mobile Support stuck at 2% and the phone doesn't show COM and a number, it's just there at download mode. If I install CloudyG ROM the LG logo appears but just 1 second, then a black screen and I can't do more than turn off the phone and try to enter again to TWRP or Download mode. Can, please, anyone give me a solution? Thank you.

If your G2 is d802 ONLY and ONLY d802

Or

Again, this is for D802, I don't know if it works with other variants. (I don't know which variant of G2 you are using)

The solution in the second url works with my LG G2 D802 - 16Gb.

Oh god, it worked. I tried everything and I couldn't fix it, but this worked like a charm at first time! Now I've got a phone and not a pretty paperweight. Thank you very much for the help! :highfive:

Hey, hoping someone can help. I have an LG L90(D415) and its stuck on the LG screen. I can boot into download mode(firmware update) and I have the latest drivers and kdz file. But whenever I use LG Flash Tool is gets stuck on 2% then says “upgrade stopped due to an error”. I went to device manager and the “LGE Android MTP Device” has a yellow exclamation point next to it, not sure if that’s the issue or not. I’ve tried this on Windows 7 and 8.1 computers, same results. Please help

Uninstall the device from your computer and uninstall the lg drivers. And then reinstall the lg drivers and then plug you phone and try again. Seems like a driver problem.

Have you ever attempted to edit the build.prop file? Also, did you know if your device has a tot file available?

Yes, I did attempt to and yes there is a tot file for my device. Although I'm not sure what a tot file is/does. Did I perm brick my phone by editing that?

    Normal Flash: Flash ROM without losing any data. Only use this when you need to fix system error. Beware of boot loop when flashing ROM that differ from current ROM on your phone or MOD ROM.
    CSE Flash: Choose this option when you need a fresh format. All data will be gone. It's suitable for upgrading or downgrading ROM or simply use this when you need to back to Stock.
