hi,
so i'm trying to update my firmware, i have s-off and m7_u version, and supercid, so can i upgrade using m7_ul firmware? cuz all the threads explaining the process has only ul fw.

this is what i get from getvar

INFOversion-bootloader: 1.55.
INFOversion-baseband: 4A.21.3
INFOversion-cpld: None
INFOversion-microp: None
INFOversion-main: 3.63.401.3
INFOversion-misc: PVT SHIP S-
INFOserialno: ****************

INFOmeid: 00000000000000
INFOproduct: m7_u
INFOplatform: HBOOT-8064
INFOmodelid: PN0711000

finished. total time: 0.065s

what firmware version should i be installing ? cuz some mentioned that jumping to the latest one from an old version might erase phone data. another reason is that i can't find my current fw 3.63.401.3 mentioned anywhere.

yes you can use M7_UL firmware, they are the same device, its just the UL comes with LTE and the U doesn't, just means the LTE parts of the firmware wont be installed, it doesn't mean you will change your device into an LTE device, you can use any files for the UL on the U, RUU's, firmeware, custom rom's etc.

Also when flashing firmware as you are s-off you don't need to worry about only going back 1 step, you can flash any you like, just be sure to read the OP special instructions first and also make sure your cid and mid match the firmware, also, if you are flashing a modified firmware, ie no red text, you can never go S-ON, this will lead to an instant brick.
