HELP this is driving me nuts.........................................

I'm looking for some advice;..complete that is;..instructions as to where and how to update the TF101 from 4.03 to Jelly Bean 4.22 or whatever the latest update may be at this time;...any acknowledgement please

OK. Let's start at the beginning.
I have gotten my hands on Asus EEE Pad Transformer TF101. Just the tablet. No dock/keyboard. It was really cheap. I was told it came form USA, and I'm in Europe. I have no warranty, and even if I did, it would've been over the warranty period by now, so RMA is not an option.

It's obviously rooted, has a custom rom and recovery (ClockworkMod Recovery v3.2.0.1. roach2010-tf101-r1)

This is what it says in Settings > About:



It seems to be working fine, except for being totally filled up with apps, bloatware and data. Natural instinct was to install a clean ROM. I wanted to go with CM, and a newer Recovery, but I got stuck on the first step. I can't get it recognized on any of my computers. Both Windows 7 and 8.

However, when I plug it in, I get; USB device not recognized. One of the USB devices attached to you computer has malfunctioned... This happens when I connect the USB cable when Android is booted up, when in recovery and also in APX mode, providing I have entered it (I'm not really sure because the display is always black).

In Device Manager, I can see only one exclamation icon (I did enable show hidden devices) in Universal Serious Bus Controllers called Unknown Device, which seems to be from the TF101. I tried uninstalling it. Restarting both the tablet and the computers. I tried to manually override those Unknown Device drivers with ASUS Android USB drivers for Windows and Universal_Naked_Driver_0.72 and ventana apx driver, but it wouldn't take any of them. I also tried installing them manually by right clicking on the INF files, and still nothing.

Then I thought I could mount the sdcard or USB mode in recovery, but that wouldn't work either, since the current recovery doesn't seem to support mounting either the internal memory nor the sdcard.
So now I am stuck. I know I can transfer files by other means, but I need to flash other ROM. Either Stock or Custom. How can I do that without the USB?

Any solutions?

I have been using EOS4 JB and so far it's been running smoothly.
The only problem is they don't have japanese physical keyboard to choose.

I Have been searching around to find solution for this but no luck.
The closest thing i can get is changing system/usr/ asusec files, but still 2 keys are missing, the 'Yen' and '\' is not working.

Facing this problem I think I have few options:

1. try to find out the way to re-mapping the keyboard map of the custom RoM
2. find a way to boost performance of the stock ics rom and hoping that someday EOS4 will support japanese keyboard

any other suggestion, or perhaps solution?
