For instance, they were warning people to hold off on the MDL to MK2 because of the bootloader and KNOX issue but people didn't research and now some are having problems and it is too late, you can't go back. If you did the OTA update or through Kies you are stuck with MK2 and KNOX. For most people it's no big deal, but if you enjoy modding your phone it can be a pain in the rear.
Picked it up with the MK2... was trying to do a SIM UNLOCK without paying $30US (The IMEI unlock is $30, the USB/software unlock is $15... and the debug unlock is free...but it looks like the debug is done away with in MK2)...
Should have probably mentioned, this is a Metro PCS flashed with TMo rom (did that to try to get the debug menu to work correctly as there has been some luck with it)... Anyway, now the fun part of getting back to MPCS...
On a side note... you guys know about the Re-Partition flag in Odin? You guys here in XDA make it sound as if its a good way to brick a phone... in the MPCS forum (on a dif. site)... has that mark checked when flashing back to the MPCS rom (stock) from a TMo rom... any ideas?
