custom zvd may not get OTA, u must have install stock ROM to get OTA automatically.even if u manage to get OTA in custom ROM u will end up in soft bricking,
so unless ZVG tot file is available u have to install older stock ROM and then upgrade to ZVG
Ok so if i go into stock zve by tot method then will i be able to work cdma with data? And also in zvg will it work with omh sim?
