I got a G Pad 8.3 with V50010b firmware (android 4.2.2) and I've recevied via OTA the possibility to upgrade to latest version.

Is this a "good" (no lags, bugs...) version or is it better to wait and keep the default firmware?

If you vote for the "no good", do you have any other firmware newer than V50010b to suggest?

Thanks in advance!

After that you can download and install from this thread Be sure to grab the version for 4.4.2

Thanks this has almost worked for me but I wonder if anyone can help! I rooted using Towelroot and have followed your instructions above, however I can't install TWRP. I boot the device to recovery and if I try to install it from the SD card I get the error:

E:failed to mount /sdcard (Invalid argument)

I've also tried to apply the update from ADB (using the executable from V50020_aboot_twrp_v2) but when I do this it tells me:

E:footer is wrong
E:signature verification failed
Installation aborted

I'm stumped now! I've search for solutions to both these errors but I can't find a workin solution or one I can understand! Can anyone offer any help please?


EDIT: I got it working, by following the instructions here: Had to unroot first using SuperSU then re-root and continue as detailed.

I get
Fastboot mod started udc_start()
on my lg pad 8.3 V50020d
after doing this.
How can I get back to original? If I understand right TWRP cant be install after latest Factory update and this is my last LG.
Normal boot = no problems but I want CM on my LG Pad!

I then used the .zip file found in this post...

This worked for me.

Let me know how it goes.

There will be a section in the file that looks like this...

if %FWVER%==4.4.2 (
if /I %MODEL%==LG-V500 (
if /I %FWBUILD%==KOT49I.V50020a (
if /I %FWBUILD%==KOT49I.V50020b (

This is checking for the version of the 4.4.2 on the device and since the version on your tab is 20d it will error out...Just go ahead and change the V50020b to V50020d, save the file and try again.

thanks a lot works for me having v50020d
