Huge downgrade problem

[deepimpact26]

Hello there,

i upgraded my jam to FW

ROM WWE 2.03 FOR HTC MAGICIAN (JAM)

and all did work..

but many thanks dont work. So i want do "downgrade" to the firmare i downloaded here in the wiki (I installed it one time before i tried the new one. So i can say that the installation of the originalfirmware that i downladed here at the wiki works fine)

So i want to Downgrade also ti This firmware:

OS 1.13.01 / ExtROM 1.13.129 / Radio 1.12

But when i want to install the new firmware i become the error message:

Backup Battery very Low

But the Backup Battery is at 100 percent...
When i do a hardreset and then install the FW the installer of the firmware tells me a connection error and the JAM reboots into the OS...

So what can i do to downgrade?!

Please help

Well, I had that problem to, about low battery!

What I did is leave the usb cable connected to the phone and went in bootloader(the screen of the phone was off) and then Ijust ran the official ruu and it installed!

Stuck is the status of jam, I thinks!
I have too!. You should check that What the PC's recorgnized your Jam or it show Unkown Device
I thinks we can solve this problem, please look for Stuck threat

2.03 is a cheat. Its not WM5 . Its the same old 2003 SE with crossbow theme and icons and etc. That russian fellow cheated us all. Even my camera is affected.

My pda cannot be downgraded, too. The 2.03 is a bad one.
