Hi All,

I have S3 T999v – Wind variant running on stock 4.4.2 , overall I hate this kitkat experience...

My issue is whenever I try to flash custom recovery TWRP (2.7.1.0 or older), it installs but when I try to take backup it shows nothing to take backup of (no System , no EFS etc....). When I try rebooting it gives error “NO OS Found” I am able to proceed anyways and it starts up phone fine.

Can anyone tell me what could be the issue here??? I wanna downgarde to either stock 4.3 or to install custom liquid smooth 4.4.4. but would prefer to take a back up just in case.

BTW my phone is rooted , rooted it with towel root.

Also can I flash T999 (t-mobile) based recoveries onto my T999v ?

Would appreciate your help .

Thanks

I recommend using d2tmo recoveries over d2can. More roms will be flashable. And you can use any rom here in our forums.
For now, try using either cwm or philz recovery. Youre experiencing a known issue that I believe is related to the hardware revision. I keep hoping to attempt a fix, but just havent had time yet. But for now, one of the other recoveries should work for you.

Knox. They prevent any downgrading to protect against tampering with Knox secure containers. You can't downgrade anymore, period. Anything beyond 4.3 or with Knox will be this way from now on.

Yeah just like doc said, if you're on 4.3 firmware you can't downgrade firmware to 4.1.2, or if you're on 4.4.2 you can't downgrade to 4.3 or 4.1.2.. Anything lower than your current firmware is a no.. You can only flash equal or newer firmware
