SPV C600 can't update firmware

[Guest Teo2005]

Please help me with the following issue:

I bought recently a SPV C600 from ORANGE RO, with the following versions:

IPL 1.00

SPL 1.00.0009

on the green band says Tornado IU

ROM 1.0.9.0

Operator 11.1.10.3

RTL 2.002

So, I wanted to flash with the Imate SP5 software (I-mate_SP5_NRE_1.5.333.0).

I decertified and SIM unlocked the phone (SPV-Services), I erased operator

field from header (with TyphoonNBFTools) but when I tried to update firmware,

the phone entered in bootloader mode, (with RUU at top-right of the screen)

and I received the mesagge "Error 2??: Update Only.")

I used the NBFViewer from the update and saw that the ROM version of imate

firmware is 1.0.8.0, so it's kinda downgrade and I understand that newer bootloaders don't accept that. So, what's your advice?

I tried to set CID -> SuperCID (11111111) with SPV-Services, but again I'm not

allowed to do that (secret writezone patch attempt - invalid data) or smth like that.

What are my options? wait for an update that superseeds the present? should i try to emergency flash the bootloader with a lower version? it is ok to do that with a bootloader from imate or ONLY with one from ORANGE firmware? Is there any posibility to SuperCID the CID (wich seems the most convenient sollution, but I couldn't figure out how to do it reading the post from Low-Level Discution topic)?

Finally, the firmware for sp5m is ok for C600, or should I stick with sp5 roms?

Sorry if my english is bad.. but i'm new in this stuff, and any suggestion ids welcome.

Thanks,

Teo
