[Q] Huawei U8800 Error - E: Can not mount @ (or / dev/block/mmcblk0p6)

Hey there all the cool ppl,
I have been reading almost all the posts and forums, yet cannot zero in on how to fix my smartphone.
I have Huawei U8800 (FCC ID QISU8800)
I took it to repair shop, they tried flashing ROM but didn't work.
The last guy had a solution, I am surprised at their tech-ability, goes by the name of J TAG and they use RIFFBOX (www.riffbox.org). But the actual person who could do it is in Dubai.
I'm not a hi-tech person, yet I need to find out few things.
If any one has some time spare, do help me.
It takes ages to understand without assistance.

Some of the links that I worked on are listed below

[LIST]

a. Is the OS of cellular smartphone like Desktop OS? Like, same principles apply? FDisk, Create partition, Format and install OS?
b. I want to fresh/ clean install from scratch, my Huawei U8800 (Not Ideos or any other model). What should I do? You can recommend me some link.
c. Since I am getting the following error, please help me in that also. I tried flashing ROMs, it would go upto INSTALLING 2/2 and give error. When I go into recovery, android system recovery <3e> it doesn't wipe data/factory reset nor cache.
