Problems with Bootloader on XDA I

[mango]

Hello, GREAT FORUM! :)

I have installed 4.01.16 ROM from lumpistefen kitchen. It's working normal, but a little buggy for me and i wonna to return to my origial 3.17 O2 ROM (i have nk.nbf).

But i can't do it from XDATools directly. The only way, as i see, is update from bootloader. I haven't SD card reader, so i write my 3.17 ROM with XDATools on 128 Mb SD card, using builtin XDA SD card slot.

Then i restart XDA to bootloader (press power+soft reset), which shows me following on the screen:
Wallaby Bootloader
5.15

GSM OK

That's all! What should i do next? How can i start re-flashing?
Can it be bootloader problem? Can it be solved fixed with pnewbootloader from XDAUtilities package (from XDA-Developers). Or i can make my device not loadable at all? :(

One remark: After rebooting WM2003 promt me to format my SD card to make it readable. Is it correct? Or there are some problems in SD card writting process..

Please, give me some ideas, what should i do! :wink: How can I re-flash my ROM?

I had a similar problem. I tried using XDATools to write a ROM to my SD card but when rebooting-with power key.. it went to the diagnostics screen directly. So I used XDArit1.exe to write to the SD card and this time the XDA recognised the image on the SD card and went into the SD Download screen. But to do this I had to borrow an SD Card reader from a friend.. Oh Also. I did make sure I had Bootloader 5.15 before I did this.
