Howdy all!

Did you install TWRP and then take the OTA, now you can't get your phone to boot normally, but you do see TWRP?

Here's the easy fix:

If you have ADB access, plug in your phone and run this:

Code: 
adb shell
dd if=/dev/block/platform/msm_sdcc.1/by-name/fota of=/sdcard/fota-backup.img
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota

Then you should be able to successfully reboot your phone via the TWRP menu option, or via a simple reboot command in adb.

If you DONT have ADB access (because of an early build of TWRP), you can simply use TWRP's awesome "terminal command" option to run the following:

Code: 
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota

You'll have to type that whole thing out, and be VERY careful with spaces and punctuation. One wrong letter and you could nuke your phone.

After that finishes, you can reboot and continue on your happy way!

Let me know if this helps anyone!

As usual, I'm on #lg-g2 in Freenode as IOMonster, if I'm around I'll be happy to help wherever I can.

I am rooted and installed TWRP recovery but reverted back to the stock recovery before accepting the VZW OTA update. I'm now stuck in a boot loop and I can't get ADB to recognize my device when plugged in via USB. When I plug in my phone it shows the following:

Fastboot mode started
udc_start()
-reset-
-portcharge-
-reset-
-portcharge-
fastboot: processing comands

Any idea why this is happening and how I can get my phone to boot normally?

Thanks it worked!:laugh: Should I flash stock now update via OTA then reroot and reflash TWRP??
Click to expand...

I didn't. From what I've read its just best to flash the new TWRP and not worry about the new OTA. Besides there is nothing relevant about the OTA enough to worry about going through all the trouble of installing the OTA. Also the devs have pulled all the new update files and they will use those in their Roms

Yea, let's just wait for a ROM worth flashing and "F OTA"

    What worked for me was from the TWRP terminal command was to type

    dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota

    then hit enter

    type

    dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc

    then hit enter and reboot.

    got help from the IRC xda-devs for the second step to complete the fix.

    When you see the file folder just ignore that and hit "select "on the bottom right and that will bring it up. Just type the command from there

    not an error.

    if wiping FOTA alone doesnt work just try wiping MISC as well.


    adb shell

    dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota

    dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc

    reboot the phone... hope it boots.

    FOR MY FRIENDS WITH WINDOWS 8...

    I tried to use this method but the driver don't recognize the phone (in device manager the phone is recognized as "other devices" with the yellow exclamation next to it), but found that manually updating the device as it is an ADB interface (I used specifically the "LGE Mobile Sooner Single ADB Interface") allowed me to use ADB. After that it worked perfectly.
