if you do request it don't ask huawei USA, they will not help you, I requested a bootloader unlock code from huawei USA and kernel source they told me flat out no for both. Then I requested it from huawei international(CN), they gave me the code to unlock my bootloader in an hour then told me to wait for kernel source, waited 3 days then I reminded them and they told me they were still processing it and it would take time(I still don't expect it though -_-).
does the premia use the 3.4 kernel like the vitria btw, is the config in proc(like most devices)
