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

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.

There doesn't seem to be an FTF for the C6806.

What would happen if I upgrade through PCC and then just do step 3?

If you upgrade through PCC phone will lost root. You have to do step 2 and then search c6806 kernel and flash in step 3

Where do I find an FTF for the C6806? Ideally Bell Canada.
