cab file errors

I am having problems with the kdz reflashing method. I have the ATT LG E980.

I am using the old lg tool, because it is the only one that I could get to work... now i have come to this error

Cab extract error

anyone knows what to do from here?
[LG Optimus G Pro] limzm:
I have to say this KitKat version for LG Optimus G Pro really feels unfinished.

I don't know but many of the animations are half-baked. Like the launcher's app drawer animation when open. Doesn't seem as nice anymore.

Plus pressing the back button in any window (like Settings) invokes the 'open animation' rather than the close, looks so weird.

Hi Hyelton, can you please confirm or check whether there's also kdz for e988 kitkat update for the Philippines? Some Filipino users have reported they have received the OTA update already. I flashed back with lg mobile support tool to stock 4.1.2 and tried to update via OTA but the phone says i'm on the latest firmware. So for now I'm currently using HK stock kitkat.

By the way thanks for your work for our OGP,i highly appreciate it :)

CWM for E988 4.4.2 V20c?

Hi! I just flashed my device with 4.4.2 KitKat software version V20c. Earlier I was using SlimKat, but I had rooted on 4.1.2 and installed CWM with FreeGee. Now, FreeGee shows aboot is incompatible with V20c. I don't want to mess-up my device because I have a very slow intenet connection and it will take ages todownload 1.7GB again. So can anyone help me out? There are links on the internet to only root 4.4.2, not install CWM or TWRP.
[LG Optimus G Pro] blitzkriegger:
Here's how you could have cwm or twrp installed on stock kitkat:

1.) Make sure busybox and freegee are installed on your phone

2.) Are you rooted already? If not then you could download towelroot.apk (courtesy of Geohot). Just navigate to www.towelroot.com and click the symbol. Once apk is downloaded, rooting is just a click away.

3.) Once rooted, install GPRO recovery 6.0.4.4.apk (courtesy of Hoangnova) on this thread, under attached files section (http://xdaforums.com/optimus-g-pro/development/lg-g3-port-optimus-gpro-e980-t2827464)

4.) Once GPRO apk is installed, fopen apk and flash recovery BUT don't reboot afterwards.

5.) Go back to freegee then install appropriate recovery, it should successfully download now the recovery of your choice :)

I've a E986 with CM 12. It's really buggy so I would like to revert back to stock. I had some version of jelly bean when I bought it.

If I'm upgrading from stock 4.4.2 to 5.0.2 I should choose in flash tool Normal Flash or CSE Flash?
[LG Optimus G Pro] kombajn2:
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.

USE CSE FLASH

BTW Beware lollipop is just for Korean model of the phone.
