[How-to] Revert to LS670V9, after installing OTA LS670VC/VD, using KP500 (Diag mode)

[sfhub]

Hey I keep getting hung up at the Lg software update tool. at 30 percent it tells me to restart. gives me this.

15:00:41 : _IsConnectedPhone Call
15:00:41 : _IsConnectedPhone(0)
15:00:41 : 0 - NotConnected.
15:00:41 : 1 - Normal connect success
15:00:41 : 2 - Emergency connect success
15:00:41 : [009,400,102,102,102]The USB cable and your cellphone are not connected.\nPlease connect your phone and wait for connecting \nthe USB port for a while and press the [009,700,147,062,092]'Restart'[009,400,102,102,102] button.

tried unplugging it, plugging back in. installed the update tool in compatibility mode as well. don't know what to do. any ideas?

So it started the flash process, got to 30%, then complained about the cable?

Sounds like something is going wrong with the cable or drivers.

I've never seen it stop in the middle of a flash.

HI, I am trying to revert to LS670V9 and when connecting to phone gets to 100 per cent appears a window that reads: UPDATING IS NOT POSSIBLE DUE TO A FATAL ERROR WHILE THE LG MOBILE PHONE SOFTWARE UPDATE.
Please help!!!!!

Haven't seen that error. How far along are you in the process? At 100%, the phone should have rebooted and be in the process of restoring NVRAM. Is your phone booted into Android?

I sometimes get that. Just do it again.

You shouldn't lose your data, but things may start behaving funny causing you to reset everything, or at the minimum wipe data/cache. Also whenever you do flashing, there is the chance stuff gets reset.

You should always backup your data before doing any flashing.

As to rooting, that will definitely not cause you to lose data and you will not have to wipe data/cache.

Do you reccomend a good free backup software to use?

If you want a full backup of what you have now, just do a nandroid backup after you root and install a custom recovery.

If you want backups at the application level, then I'd suggest Titanium Backup (again after you root).

Do you have a directory C:\KP500-Utils-EN-v0.4.2

Which of the commands gave you that error (there are 4 of them in step h)

well im kinda new to this, so idk what im doing. but i did move the file to the cd, and i copy and pasted the commands and didnt work, am i supposed to put all of them as one sentence? or push enter every time...for example c: (enter) cd kp500-utils-en-v.0.4.2 (enter) etc....?

 

[sfhub]

push enter every time...for example c: (enter) cd kp500-utils-en-v.0.4.2 (enter) etc....?

Yes, do that. Each line is a separate command. Press ENTER at the end of every command.
