Added link to Mike's superwipe.

Sorry for the dumb question, but ive done a search and found conflicting answers. When you wipe data and cache do you want them to be mounted or unmounted?

I have Touch CWM and I have no problems flashing back and forth between JB and ICS roms and nandroids.

You just have to flash a Super Wipe in between.

I just did this yesterday to test out my MHL adapter. Backed up my JB rom, super wiped, restored my ICS Liquid Rom, tested, super wiped, restored my JB rom.

I think super wipe is key in going between different rom builds. But I've had absolutely no problem using CWM at all. If Super wipe is the answer, then perhaps CWM's Factory Reset option isn't wiping as well as it should.

Flashing a SuperWipe is much easier then having to restart the phone a few times.

I think it may be related to Viscious old versions. Not Sure. Using Jelly Belly now. If you are not having problems, that's great. I used superwipe script. No problems. But, if people want the manual solution without getting errors, then at least we know the above method works. It might not be neccesary now with the newer releases, maybe data will unmount ok.

If anyone wants to test and see if they can restore old backups from ICS w/out doing the above steps (IE the rebooting) and report back, it'd be appreciated. I will be uber busy the next couple days or I'd take the time to backup to my computer before trying.

Would you mind sending me the super wipe script to flash? Or point me to the thread?

I'm running CWMR 5.8.0.2 and I've restored my ICS roms over several JB roms without issue and no use of any sort of superwipe script.

Are you using Touch Based CWMR? Or Standard.

I can confirm even with Jelly 3.6, that after I wipe data, cache, and delvik that the data will then remain mounted and not unmount unless I restart recovery.

This can/does cause problems and messes up operations when people are doing multiple actions in recovery at the same time. You might be able to do one action, such as making a backup just fine. But if you are using CWMR Touch, you might have issues with doing multiple operations in the same recovery session, like, backup, wiping, then restoring if the action you are doing requires data to unmount.

So, if you say "I have no problems..." please confirm that you are using touch recovery... not just standard.

CWM Touch was updated to 6.0.0.5 this week, is this issue still present? I haven't experienced any problems yet using CWM Touch, I'm just curious.
My steps are 1. Backup 2. Wipe data/factory reset 3. Wipe cache partition 4. Wipe Dalvik cache 5. Flash ROM 6. Flash GApps if needed 7. Reboot
