Hi guys, I bought a c6903 last year because didn't want to wait for the late release in the U.S. Before purchased it, I did some researches that confirmed it would only work under band 1200 for At&t in Los Angeles. Band 700 isn't supported at all. Since I'm living in LA, there are only a few places have band 1200. Most of time, my z1 is running under HSPA+.

Previously, there were someone flashed the C6606 FTF file to have their c6603 (Z) working under 2600 in Canada. I guess it would work for Z1 as well (Some CPU both C6903 and C6906) and searched on xda. Only saw some people talked about it, but no one tried it.

Therefore, I gave a try this afternoon and it works. My Z1 is running under LTE at home now. According to the Speedtest, LTE is 4 times faster than H+. lol


1. Download same version of C6906's FTF as your cellphone from
In my case, my C6603 is 14.3.A.0.757, so download C6906 14.3.A.0.757 Generic CA 1276-7484_R4C.

2. Flash it with flashtool and bandbase only.

3. Reboot. You will find your LTE is working if have the lte signal.
