Help! I have problem with upgrading

[gelemos]

Hello everybody from Russia (Moscow).

My phone model is O2 Xda Neo (Germany)
I have used this
278638-ruu_prophet_215746_2157138_023021_qtek_rus_ship
RUU_215737_2157135_023021_QTEK_s200_RUS

and return back to original O2 Germany without problem.

But I have installed next:
RUU_Prophet_220734_2207114_024721_QtekWWE_Ship

Now I cannot install any other software. only this english version.
In install time (on 95%) I got next message

error 326: invalid command - the NBF file could not be used for your PDA phone - please check your NBF file

Boot screen has
IPL 2.15.0001
SPL 2.20.0001

The phone is ok. I can install this english version again, but I would like return to original German version or Russian.

I tried to use
pdamobiz.com_downgrade_and_unlockcid
and RUU_Prophet_2151327_21513121_021921_DOP_ASIA_WWE_S hip-NoVendorID
but it does not help.


Can you help, please? :(

piece of cake:
what do you need is
reCOOK the ROM using molski.biz devpack...
just be sure to remove the ipl/spl nb file after you've extract the nb.nbf file

Hi,

I have searching for a long time and used so much tools to downgrade my Qtek S200 Pocket PC to JAMin_WWE_1000925_10009114_11420_ship.exe (SPL 1.xxx, IPL 1.xxx)

When directly run "JAMin_WWE_1000925_10009114_11420_ship.exe" I get this error: the NBF file could not be used for your PDA phone - please check your NBF file

JAMin_WWE_213923_2139123_022021_shi.exe ROM is not my solution. I need to change my IMEI. iWizard and Lokiwiz03a don't help me to change IMEI.

Can anyone help me how to do Rom Cooking for SPL 1.xxx?
