I have Verizon I545VRUEMJ7 and I am particularly looking for the ROM with Wi-Fi Calling feature (lousy connection at home). I switched to Family-Mobile who's hanging on T-Mobile network, so T-Mobile wi-fi calling should work for me.
Does anyone have experience to flash any Custom ROMs over Verizon I545VRUEMJ7 without a custom recovery (CWM of TWRP) installed. Should be data cleaned up first, some apps maybe disabled or deleted, like KNOX, or Verizon security for instance. Any advices?
Since the bootloader is locked, you can not flash custom firmware. If Hashcode gets Safestrap working on MJ7, you may be able to flash a ROM that does what you want, but not today.
My Android devices:
vzw Samsung Galaxy S4 stock MJ7, now rooted!
Samsung Galaxy Tab 2 10.1, also stock but rooted.
VZ Droid Incredible 2 rooted but otherwise stock.
