Hi xda
Here is the condition of my device......
I somehow deleted the recovery in my tablet also the OS
Now I have access only to fastboot mode
So I searched in internet and downloaded the update.zip for my tablet
But the update had the following files
meta-inf(folder)
ifwi(zip file)
System (folder)
Recovery(folder)
Boot(img file)
Fastboot(img file)
So I booted into fastboot mode and flashed the boot.img and fastboot.img files
But the recovery is not a image file....its a folder...
So I cannot flash the recovery.
So I converted the recovery folder into recovery.img and flashed it in fastboot and it gives me the following error
Recovery flash failed(remote:flash_cmds error)
How to recover my tablet?kindly help me to flash recovery
Thanks in advance
My device is digiflip pro xt811
