u1 and u are basically the same variant, with carrier sim lock etc so they are flashable.
different variant uses different signing keys thus its almost impossible to circumvent.
Variants, like u1 and u, can't be cross flashed except with patched odin.
Now methods are blocking variant cross flashing; even with patched odin.
This block is enabled by the use of values embedded in the signing of the pit. As long as the values match, cross-flash can happen (ie the first two below). If values differ, no dice (ie the remaining variants).
For instance:
G781U - ATT - QKEY1 - SRPTF19A
G781U1 - XAA - QKEY1 - SRPTF19A
Original odin will not cross flash; patched odin will. Win!
G781U1 - XAA - QKEY1 - SRPTF19A
G781V - VZW - QKEY0 - SRPTF02B
G781B - XX - QKEY3 - SRPTG02C
G7810 - CHC - QKEY2- SRPTF24A
G781W - XAC - QKEY5 - SRPTG08A
Original odin will not cross flash; patched odin will not cross flash. Bummer!
Do your due diligence with variant selection. At least till a new patched method is worked out.
