C6906 4.2.2 to 4.3 flashtool error topic

I have 2 Sony z1s. Both came with 4.2.2 stock firmware. One phone I inserted sim and did the OTA update and got it to 4.3. I then used flashtool to flash it to unbranded 4.3. The second Z1 I didnt do the OTA and tried to use flash tool to go straight to unbranded 4.3 and I keep getting this error message below. Any help would be appreciated.

[Q] C6906 - Flashing .290 branded to .290 generic topic

Hello,

I recently bricked my Z1 and just got it back from warranty repaired. It is a C6906 that they upgraded to 4.3 (.290) however it is branded to BELL and I wish to flash the unbranded generic so I don't have as much bloatware/fast updates.

Since I do not wish to brick the device again and go through this again and so I am looking for advice to do this in a way that is guaranteed. With flashtool if I flash "C6906 14.2.A.0.290 Generic CA 1276-7484_R2B" would I have any issues at all? Just load up Flashtool - select the ftf and just use the default settings and plug in the Z1 while holding down the volume button.
