Should this work with a P880 too? I am stuck at "Please Update R&D Test Tool". Can I use LGMOBILEAX,zip for the P880? My question for the P880 I have posted at http://xdaforums.com/showpost.php?p=61928891&postcount=357

Edit:

I also cannot see the mentioned "inserts" (videos?) with my Linux PC, probably because it needs flash, which is disabled because of security reasons. Maybe there is a youtuble-link?

any solution to fake the program?

it is ok to flash the rom H788, but can't flash H788n or H788x etc.

thanks in advance.​
[G2 Q&A, Help & Troubleshooting] Cluey:
Thanks.

That was a crazy, crazy process to go through. The automated script file didn't work for me so I did it all manually.

Thanks for providing the files and instructions, all that is missing is notes on when to plug the device in and in what mode. You start off by telling us to turn on USB Debugging, so we're booted into Android at that point, but it doesn't work until you get the device in download mode. At this point I don't think the USB Debugging setting in Android has any effect.

That's all the feedback as I can think to add for you. I didn't read the entire thread though, but if it has been suggested before it hasn't been edited into the original post.

Ok, the 49% flash stopping error is because /system files are not matching to the kdz you flash. On account of mismatch in md5 the flashing stops. I had this problem a while back.
