[Q] ATT branded S II lost signal topic

My wifes S II just lost signal. When I try to view mobile networks, I am told to put a SIM in the phone.

I did the usual stuff, reboot, reset sim, battery, charge, etc. No dice.
I took out my SIM and put it in my wifes phone. No signal. I put my wifes SIM in my phone, full signal.

Looks like the phones modem is fubared. I rooted my phone and install SHOstock3 v4.0. If I do the same to my wifes phone, do you think that will alleviate the problem (not recognizing the SIM)?

[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.
