I finally got my D802 working again (flashing using the .kdz method) after coming back from 4.4.2 -> 4.2.2
I just had to do a reset as phone was stuck in boot loop.
I do have a different problem now...
I can't enable 4G, I could when the phone first arrived with 4.2.2 but since upgrading to 4.4.2 that option is gone, I am now back to 4.2.2 HongKong (the original ROM my D802 came with) and I can't enable the 4G option any more...
The 3845#*802# method only last until a reboot, so does the *#*#4636*#*# method and of course I only have the GSM/WCDMA option in the "Mobile Networks" menu
! have 2 of these G2 units and the other one is completely untouched and that one works fine, 4G is there and all.
I'm worried that something must have happened when I rooted using ioroot25 (EFS is backed up) or when I flashed the .kdz to upgrade to 4.4.2 (OPEN EUROPE) ?
Flashing back to 4.2.2 (HongKong) using .kdz method went fine, the device information say I have exactly the same Android version, Baseband and Build and all as my untouched G2 but still the untouched G2 has 4G option and some Chineese bloatware installed, I did not get these bloatware back when I flashed back the 4.2.2 (HongKong) .kdz
