http://www.linuxquestions.org – hi all i'm new here and a novice(more like idiot) 1)i have a samsung galaxy ace plus GT-S7500T the t is for australia not international version. 2)rooted phone with no back up. 3)flashed inspiration_V10 rom again no back up of stock rom (S7500TDVLK1_S7500TTLPLK1_TLP.zip)V10 rom runs smooth but no wifi says error no mac address or ip address . 4)tried flashing stock rom using odin3v.07.exe few times keeps aborting also flashed few times in recovery still just aborts. my biggest mistakes were flashing rom not for GT-S7500T but for GT-S7500 and of course no back up of stock (learning the hard way (HowTos)
