First lets fix a Memory / USB Key having AU6890 or higher controller/flash chip. I was scammed and was given a Hynix HY27UT088G2M memory which is by the way 1 Gigs space total and not 8GB or anything else. So, lets flash it back to its default 1 GB value and fix this sucker good.

First of all you will need to open up your usb key case, do not worry most ebay keys are easy to open, i opened mine with just my finger nails. Some might need exacto knife or something that will do the trick. Now look at the memory controller chip.

Flip the memory key and look at what memory you actually have on the darn usb key. Here is what I had Hynix HY27UT088G2M :

Rest of it is now pretty simple if you are lucky to have the flash files for your particular memory key. Simply download Alcor 2.1.2.0 (attached so you do not have to google it for a day or more and register on Chinese based site, ooh yaa that was not fun , its not easy trying to register on a site with language out of your dictionary !!), in the attached zip file is Update.exe file, its there only if you do not find your memory in the flash List , after installing ALCOR and trying to fix your key. Now, just follow the steps below in the figure to fix your hacked usb key to normal capacity. Post your queries if you are unable to follow.

Step 2. Simply go to Setup if you key is not regonized automatically and select from dropdown the memory you have, use update.exe file first if you have to.

Now hit START shown in the first figure and it should do the format and flash it back to normal value, and if your key is all fixed back to original capacity.

Will write about fix for keys using iCreate to hack usb keys tomorrow. Bit tired right now.
