Oh, yes please, send me the link for the whole ROM firmware if you have it. I search it but i had no luck to find it.
It's only available through OTA... Since I'm at work right now, I will upload them for you once I get home. You may check DM t...
Oh didn't know that about the t1-23l, that's great!
I'll try to port the rom, it should not be a problem as they should be the same device.
Thanks! I have tried on my device and succeeded to update to emui3.1. Please let me know if you need boot....
Good news bro. I find that t1-a21l is the same model as its Chinese variant t1-a23l, whose OTA EMUI3.1 ( android 5.0) has been available. You shall download and install its 4.4 rom from Chinese Huawei site and see if you can upgrade through OTA.
