[Q] Messed up my E975... need help... :(

Hello all, on a stock E975 I installed freegee and then cwm, unlocked the bootloader and installed fastboot (i think, there's the start menu if I hold vol+ and power).
The phone shows 'google' and an open lock at the boot also.
Now, I messed up the OS of the phone and t the moment it 'only' boots to cyanogenmod 10.2.0, wifi and Bluetooth aren't working and IMEI reports all zeroes if without SIM, 'unknown' if SIM is inserted.
I know his is a big trouble since I haven't freegee backup anymore but I'd like for the moment to return to stock firmware. Onestep at a time.
So, I need help in how to install stock firmware since the various methods I've tryed so far aren't working.
I got the right E97510H_00.kdz file downloaded ith the Original LG firmware program but I am unable to flash it anymore using KDZ_FW_UPD.exe: I start with phone in upload mode but the program reboots the phone, fastboot menu comes up and firmware update cannot continue anymore and exits with an error.
What should I do to let KDZ_FW_UPD continue with updating firmware?

SOLVED!
Just made a 910k type cable, connected phone to PC and set lg updater to Emergency mode.
Stock firmware restored perfectly and IMEI is working again too.

also...
when the phone reboots to fastboot while trying to flash kdz, power off phone, dont close/exit kdz updater, disconnect usb cable, switch to download mode again and the flashing should finish. i always had success with this one. hth!

Bootloop after Xposed install, Hard Reset not working

Hi there,
i rooted my G3 using Towelroot and all worked fine.
Today i installed the actual Version Xposed Framework and after rebooting it entered a Bootloop.
So i tried to Hard Reset my G3 but when i confirm it the Android with the Gaers show up for a second and then my G3 keeps showing the LG Logo for a few Minutes till i disassamble the Battery.
Next step i try is to flash a firmware in Download mode, but i cant get the Drivers to work... =(
Someone have some hints for me?

Have you choosen ART modality?

If i would say "what the hell is that" ... would u slap me?
No.. i dont have chosen that..
Bigger problem is that i dont get any usb driver working for firmware update in Download mode.. =(

OK... i managed to get the drivers working.
But further Problem ist now that im not able to flash anything on my device...
Neither the TOT Method, nor updating with the Original LG Support Tool is working...
Support Tool tells me my Model Number and that my Version is most actual.
If i update anyway it stucks at 4% and tell me it cant connect.
TOT Tool tells me that my Version Number is not correct... but it is..
With the KDZ Update Tool it stucks at 4% like the Original method.

Same problem here
Any one can help us?

Solution
Hi there,
the Problem was my PC...
I was on a Windows 8.1 64bit.
Switched to a Win7-PC and all is working fine.
You should try to use the Original LG cable, or another "Original" Cable and connect it to a USB-Port on the Back of your PC (directly to the Mainboard)
On a blank Win 7:
- I installed the LG PC Suite
- Updated the PC Suite
- Connected my LG in Download Mode
- Let the PC install all drivers,
- Disconnected the Phone
- Downloaded the actual LG Mobile Support Tool
- Let the Support tool do the work
After this i got my first OTA Update and its working like a charme

andy

seem to have got phone working it says upgrading apps buit once its done
i get the error pop up google play services has stopped working any ideas ?

Hi!
1. Find and install the drivers for your G3 for Windows.
2. Connect your G3 to the PC by USB, switch it to Internet/Ethernet USB mode.
3. Find and run LGMLauncher.exe (LG Mobile).
4. Once LG Mobile recognizes your G3, choose the menu option in the upper right corner and choose "Update Recovery".
This will completely wipe your phone including your internal storage, get the latest stock ROM for your phone. It might unroot it too, so be aware.
Maybe anyone else with more experience will have less radical suggestions.

Hi it's working using the LG pc suite did optional step and factory reset and phone is back to stock no root or SU on device so I think I'm back to stock and good to go.
Thanks for advice though
