I have a Asus tf700t tablet running 4.2.1,i want to upgrade to 7.0,bootloader locked, I tried the V8 Asus unlock tool,
Received "unknown error,possibly network problem, try again later, Researched, couldn't really find a solution,essentially said server issue with Asus
Debugging enabled, unknown sources enabled, Play store Play protect off, there's a setting in Google Chrome, but I can't remember what it is, maybe someone here can help with that also, I'll change it if I can find it, Developer options enabled, no option for OEM unlock
I would like to unlock the bootloader so I can use Twrp to update the OS, no longer any updates available
BTW,device is rooted,SU installed
Thank you for any help or advise, if needed I can provide build number and kernel version, it's an older tablet,but does have the good Tegra chipset, and definitely works well, but slowly,,,,
