Backing up samsung rom? - General Questions and Answers

I have a galaxy a7 lite that has the bootloader unlocked. Unfortunately there is no recovery for it and I have just configured my tablet to how I want it to be setup. Is there any way to do a nandroid backup of the entire rom without a custom recovery?

[Q] can online Nandroid recovery be used instead of Cwm recovery?

I have a Pipo Mix M2 WiFi tablet which seems to be stuck with 4.04. The device is rooted and there is a custom rom I can install. However, I haven't been able to get CWM onto it. Recently I found Online Nandroid Backup and this seems to have installed a recovery in the CWM folder.
Am I right in thinking I can now proceed and install my romantic from the sd,acrd through Rom Manager?

You could
1) restore a backup if you ever made one:silly:
2) flash stock ROM (this will wipe your data though)
3)or if you're not that picky download a custom Rom(like cyanogen) of android 5 along with gapps and flash them in twrp (this will be choice if hadn't made any backup that I could restore)

Did you create a backup of your stock ROM before you flashed the custom ROM? If not, you should have. A prepared user always makes a backup via TWRP before making any kind of changes to the system and before flashing ROMs, that way they can restore the backup via TWRP if something goes wrong.
Can you boot into TWRP?

I solve it by removing battery and then boot in recovery mode and flashed stock firmware , but I still can not install custom rom

That is because you triggered Knox, you won't be able to flash anything custom now that Knox has been triggered. The firmware that you flashed, was it the same build number as what you had originally or is it a newer, updated firmware? If you flashed a newer firmware that has a bootloader that can't be unlocked, you will not be able to flash TWRP or custom ROMs.
