Step 1: in folder "Buoc 1"

  1. Flash 14.1.B.1.532 by flashtool. Start phone, turn on USB debugging (skip lost imei and signal then continue)
  2. Root
  3. Recovery
Recommend Backup TA

Step 2: in folder "Buoc 2"
  1. Copy 3 file in folder "Buoc 2" to phone.
  2. Reboot phone into Team Win. ( Press Power wait green led then press and hold "volume -" until red led release "volume -"
  3. Wipe -> advance wipe -> tick dalvik cache, cache, data -> wipe
  4. Install 3 file Rom, Recovery, SuperSU -> Do not reboot but go back to the main menu, then go to reboot->power off

Step 3: in folder "Buoc 3"
  1. Copy file in folder "Buoc 3" into fimware of flashtool
  2. Run fashtool flash file C6802_14.3.A.0.757_TW kernelonly.ftf.
  3. Reboot phone
  4. Finish

Another way better

You do Step 1 then reboot TWR flash c6802_14.3.A.0.757__flashable.zip --> power off phone --> flashtool flash C6802_14.3.A.0.757_Stripped.ftf --> finish

This is already more or less written about 5 times in the ZU section, but good on you for taking the time.

Change the 532 ftf for the one by [NUT] then you can make the first section simpiler as there will be no IMEI issues. See my downgrade thread for the download.

In second section put a warning about that the phone won't be in a bootable state at that piont

exactly the same for the other models, just change the firmware to c68xx
If I am already on rooted .290 can I just flash straight to 757?

Or do I need to go through the whole .532 downgrade drama again?
@blueether if you don't mind, could you write me up a very quick process to get from rooted .290 to rooted .757 on the C6806?

I'd really appreciate it.

hi
i have LB zu 6802
and install this rom step by step
i have supersu and when open program for example dxtoolbox or titanium or freedom ask me for grant root premission
but
it's really not fully rooted, It's like a light root but it's not really real
my program not work good
for example
in titanium
i uninstall a program(google+)apparently unistall that when close titanim and open again see google+ and other program too...
in dxtoolbox apparently close program but programs are open
apparently disable startup programs but after restart open all program

in x-plore when delete a file from root/system apparently delete this but when close and open x-plore i see back delete file

in freedom say this error write permission on system partition are required in order to use freedom

Will this ftf file that has to be flashed using flash tool work for the 6806 flawlessly, because it is named for the 6802?

Don't want to lose lte or something.

Plus is this full root?

@blueether I have a separate Rom, my question is about the file that is flashed through flashtool?

---------- Post added at 08:33 PM ---------- Previous post was at 08:00 PM ----------

If not, can someone make the stripped FTF for the 6806 please?

I'm ready to upgrade but us 6806's seem to have been left behind this time around. :(
@blueether, @[NUT], @iragon, @jackie099?

Thanks a lot.
