It's more of preventive foresight ...
For starters ,I don't approve of nandroid backup as such .
On Mtd-nand devices the backup are pure images as against tarball archives on emmc .
I don't know the restore mechanism on mtd nand ...
If it is a disk image ,restore can be brought about in many ways.
First it can be pure nand and use offsets and size like we define in config_cmdline....that will be proper nand restore....in that case the restore will fail since the partitions were reallocated in recovery...
Second it can use a disk dump starting from offset ...
if by any chance there is no safeguard to prevent (rare case)
Third it can be a simple mount and copy ...if in this case there is no safeguard then data will just be overwritten(I can confirm this scenario)
Then it's pretty stupid to use disk images instead of tarballs but that's another matter..
That's due to part of my ignorance of restore mechanism of nandroid. As such I can't guarantee the consequences nor I want to dwell on it .
Auto nandroid restore doesn't work ...advanced nandroid restore might work ...but the responsibility and consequences is totally upto the end user .
That's one thing...Another thing is ,I can only vouch for the recovery in doppler ...if someone backs up a doppler image and uses it on another kernel which has a recovery compiled differently or someone else then it's beyond my reach and time to support such issues...which I don't intend too ...
The second part is I am skeptic of nandroid backup as such. In my opinion ,nandroid is worst backup ...
I don't use it personally and I won't test it or "try to amend" it or explain how exactly nandroid works...
It's a 1GB waste of space ...
The third thing is there are many pointless discussions held on threads related to nandroid..especially the ones with twrp and cwm ...I want to avoid such discussions as such ...
Keeping these things in mind I felt it was better to declare nandroid as broken permanently..
Than to discuss pointless on a partially broken system which is flawed in my opinion and serves no purpose ..
People who want to use restore can use it at their own risk . I don't support it as such or intend to ...
