    Default Boot to Recovery After Stuck in Boot Loop

    So here's the situation. I may have bricked my device, but any help or suggestions will be appreciated.

    I rooted my LG G2 (Sprint) successfully. I installed TWRP successfully. I booted to recovery, performed a backup and did a wipe successfully.

    I downloaded the 2/1/2014 AOKP and the corresponding GAPPS. Copied the zips to my Downloads folder on the device, rebooted to recovery and flashed my device. That all went successful.

    However on first boot I waited almost an hour, and the boot did not complete. I believe its stuck in a boot loop.

    I tried doing the physical hold volume down + power, then release power on LG screen and push power again to get into recovery and it seems to ignore this attempt and just keeps trying to boot.

    I don't seem to be able to even fully power off the device. When it does appear to power off while holding the power button it's like a restart.

    Anyways I'm stuck, wondering if I bricked it if I can't get into recovery to do a factory reset. Any suggestions?

    Thanks in advance.

    Welcome to the forums.
    Did you do a clean install of the ROM?

    Thanks for the welcome!

    Well... That's a good question. Did I do a clean install of the ROM. What does that mean exactly? It's been a few years since I rooted an Android and applied a custom ROM (we're talking back like version 2.6 era or therabouts), so I read up quite a bit, but its entirely possible I bombed it by missing something very important.

    The most frustrating thing at this point is that I can't get to recovery or factory, which correct me if I'm wrong is done by the following steps:

    1. Power off phone.
    2. Power on the phone while holding power and volume down.
    3. When LG screen appears release power and volume down and repress.

    I'm thinking I bricked it, which is frustrating to say the least, but I'm trying to be realistic. If I did, I'd like to figure out what I did wrong technically.

    There may still be hope. I can get into download mode by holding volume up and plugging in the usb cable. Problem now appears to be drivers. Windows (Win 7 64Bit) fails to install the CDC Serial driver. It does install the USB Composite Device as well as LGE AndroidNet USB Serial Port (COM4).

    I'm thinking if I can get Windows to recognize the device drivers (or install the correct ones) I may be home free and be able to access the phone with ADB to hack around and recover, although it may still be a challenge to figure out exactly what to do.

    I've had a heck of a time with the drives. Prior to getting ADB to recognize the device previously it would not work with:

    LGUnitedMobileDriver_S50MAN310AP22_ML_WHQL_Ver_3.10.1.exe

    Windows did recognize it as LG Portable Device after installing:

    LGUnitedMobileDriver_S4981MAN38AP22_ML_WHQL_Ver_3.8.1.exe

    The 3.8.1 driver appeared to work and be recognized. I had access to the device in debug mode via ADB after doing that. I was able to use ADB to copy loki_flash and the TWRP recovery.

    This is the first time I've booted to download mode though, and windows doesn't recognized the G2 or needs additional drivers. Anyone have any ideas? I'll keep playing with the drivers and see if I can get to the point of access to the phone with ADB.

    Try downloading updated drivers for LG.

    Clean install means cache wipe and factory reset before flashing the new ROM.

    I believe I did, but it is possible I got distracted during the process.

    At any rate this guy knows his stuff.

    Used this process and got back up and running on stock:



    I'm good. Now I know how to recover and have the tools to do it, I'll be even more bold messing around with ROMs.

    Thanks for the replies.

    hi, I have the exact same problem as OP. Only actually it's a tad worse as I cannot, for the life of me, get the CDC Serial drivers to install.

    I have uninstalled all my (old) phone drivers etc, and ran registry cleaner. I have then installed 3.8.1 driver via LG Mobile Support tool.

    If I could get either the MTP driver or the CDC driver to work I could access the phone.

    I've found this website where you can download the CDC driver ( CDC Serial Drivers Download for Windows 7, 8, XP, Vista ), but I don't know where to put them.

    For now it looks like this:

    Anyone have an idea how to get CDC working?

    Im Using the LG software tool and I got my LG G Pad 8.3 tablet into download mode by holding down both volume buttons and the power button. If you have the software from this site it should fix any LG phone or tablet. some phones and tablets have this recovery tool so be sure to check your phones brand.
