[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] doveman:
Still on v2.6, I'm having some weird issues. Using Online Nandroid backup to make a TWRP or CWM backup, it completes but then gives an error right at the end about creating/copying the destination folder/files. This only happens if I set the destination as the external sdcard1, not if I set it to sdcard0.

So I created the backup to the internal SD and thought I'd copy it to the external (as the internal is encrypted it won't be available from recovery) but although that appears to complete, using ES File Explorer it shows an empty destination folder (other than recovery.log), whether it's named TWRP or TWRP2. However, I just found that I can see the files on my PC if I connect the tablet to that, they're just not showing in ES File Explorer, even though I have Root Explorer and Show hidden files enabled (not that the files are hidden I don't think).

Another weird thing is that the TWRP folder on the internal isn't visible from the PC. I was going to copy this to my PC as a backup but obviously I can't if I can't see it and I'm not entirely confident that the folders on the external SD aren't corrupted, so I don't want to rely on those.

EDIT: Strange, after rebooting my PC and the tablet I can now see the TWRP folder on the internal SD from my PC. Copying the folder from the internal to external SD with ES file explorer still fails though (I checked the previous attempts and most of the copied files were 0B) and shows only the recovery.log in ES and a total of 251MB of files when I look from my PC (the original folder is 1.13GB) but at least I can copy it across with my PC.

Seems I can't copy from the internal SD to my PC using the PC either, as it just errors out so I'm having to copy my Titanium backup folder (2.5GB) to the PC via WiFi using ES to copy from the SD to LAN, which is going to take ages.

EDIT2: I'm still having the same issues after wiping and installing v2.7. Online Nandroid Backup can only make a backup successfully to the internal sd, browsing from Windows Explorer doesn't show even the backup folder under clockworkmod but only two hidden files ".last_install_path" and ".recovery_version" which ES only shows if I enable Show Hidden Files, nor can it see the old /sdcard1/clockworkmod/backup folder I made previously, only the blobs folder and the hidden ".recovery_version" file. The only thing that has improved is that I seem to be able to copy the clockworkmod/backup/x folder from the internal to external SD with ES now.

EDIT3: OK, I flashed back to stock ROM (after flashing the stock boot via fastboot, I couldn't find an option to flash an img in Philztouch) and that 's fixed the problem with Online Nandroid Backup, which now shows the Required Space when running the backup (before that line showed no value) and I can successfully make the backup to the external SD. However the problem with not being able to see certain files/folders in Windows Explorer persists though, so the backup I just made to sdcard1/clockworkmod/backup/date_time is not visible but the folders/files for the previous backups I made do appear and although I just made a backup to the internal SD, no clockworkmod folder shows at all for that in Explorer but does in ES.

So as the only thing that Stock has fixed is to allow me to make backups to the external SD and that's not the biggest problem, as with DoPa v2.7 I was able to copy them from the internal to external SD, so I might as well flash back to that.

EDIT4: Latest problem I've run into with v2.7 is that after encrypting (with stock recovery installed, as otherwise it just reboots when you try and encrypt), when it boots and asks for the password no keyboard appears, so there's no way to enter the password and proceed. So I'm going to have to wipe everything and start again with the stock ROM. Has anyone else successfully used encryption with v2.7 (or v2.6)?
