sorry for late reply, i managed to download grey and red pre portico for my devices, now i am updating my lumia 822's to portico and see if everything is up to snuff.
now i am going to do some frankenstein stuff. since for some reason, mms is not receiving correctly from straight talk on the 822 (AT&T version of straight talk)
i am going to try to flash unlocked developer 821 firmware to the nokia lumia 822 and see if
1. flashing process is success and not a bricked phone and hopefully make it pentaband
2. and see if everything works with at&t, and tmobile and straight talk
i want to flash unlocked version because AT&T 920 firmaware may or may not sim lock device to AT&T, i doubt it. I want to be safe than sorry. Since the 822 comes sim unlocked already
and also on the unlocked developer or unlocked version or rogers of lumia 922 will have AWS bands. I think Rogers and AT&T LTE are same frequencies, but mainly looking to test to see if the LTE radio to work from Verizon to AT&T is a firmware/software flash to enable AT&T LTE on a 822.
That way i might also flash a 920 lumia i got to the 822 verizon firmware and see if it takes. but i may have problems with the 920 not being sim unlocked and it wont take the service. but i will be able to see if it reads LTE on the signal meter when i pop the verizon 4glte sim.. I doubt i will get CDMA to work, but like i said i have the time and phones to play with.
This way i want to see if only if i can get a lumia GSM 920 on Verizon network for the 4G LTE. I live in a strong LTE area and will most always have LTE.
Then i can beg and beg and beg att to give me the unlock code.
Since here in the forums AWS was lost when flashing a Rogers Lumia to an AT&T firmware and now i will take this to a whole new level of testing. If someone has already done this please tell your findings.
I wont be able to do this until Friday night
