Root Can't mount sd-ext

[Code_Monkey]

I'm having a problem restoring from a ROM flash that doesn't seem to be working.

I am using a ViewSonic G tab which I had originally rooted to CryonGen7 (bittrix-beta-06.43f-gb). That was the first time that I had rooted my tablet and it worked fine.

Today I attempted to root the device to VegN 7.0 (VEGAn-GE-7.0.0-RC1-Harmony-signed). I followed directions, wiped the cache, data and the dalvik. I performed the update using CW and once I rebooted I waited approximately 15 minutes for the system to rebuild the dalvik database and cache. Since that was 3 times the required 5 minute wait, I figured something had gone wrong and powered down the tablet.

Now the problem that I have is that I neglected to copy a rescue update.zip file anywhere on the internal SDcard and when I attempt to mount the ext-sd card which has the rescue update.zip I get an error:

E:Can't mount /dev/block/mmcblkOp2
(No such file or directory)
Error mount SDEXT:!

I pulled the sd-ext card and mounted it in my windows system so I added the directory structure, but it wasn't recognized. So then I thought I'd just reformat the sd-ext card and see if the system would add it but I received the following errors:

Formatting SDEXT:....
No app2sd partition found. Skipping format of /sd-ext
Done.

I have also attempted to mount an external USB flash drive without success. Any suggestions on how best to proceed at this point?

I appreciate the help from anyone that takes the time to reply.

It sounds like there is no EXT partiton

shadowninty,

That may be, the drive appears to have been formatted as I do have some file directories under it that mirror the sdcard directories.

How would I go about creating the EXT partition since I only seem to have CW available and it doesn't seem to want to format it?

In Advanced menu of CWM I think there is an option
Alternatively use GParted on a computer

Thanks for your help. I did finally find out how to get my backup update.zip over on to the external card and was able to re-flash back to CryonGen7 (bittrix-beta-06.43f-gb).

I appreciate the reply and time.

Are there any ROM for ZTE Blade CDMA ? Thx.
