Hello Everyone, nice to meet you all
first of all, i'm using CAT B15 Single SIM Version.
well... i have followed the tutorial above (page 1)
i've backed up all the data, and trying to mod the recovery.img and boot.img using MTK droid tools, then flash it again into my device, unfortunately it stuck at bootloop... i have tried several ways to solve this (restore backup data, etc) but nothing seems to work out...
then some desperate thinking comes, i downloaded the dual sim firmware (the rooted one) and flashed with my scatter file, the results are quite surprising, i got my phone back up, all running very well except that SIM 2 icons on the top and no data connection this time...
then what am i supposed to do? should i edit the built.prop? init.d? or maybe porting to another ROM? (any suggestion about any MT6577 device running on single SIM?)
*note : i bought this phone far away to Indonesia, and it seems the 3G freq is different from the US, last time (before bootloop happens) it can only receive EDGE data connection, but after i flashed to the DS stock firmware, there is no data connection at all, i've checked the engineering mode in MTK mode, checking the band freq, it is the same as single sim firmware, so what is supposed to be?
thank you, sorry for the "messy" english
