downgrade radio version

should i downgrade the radio version when i want take my o2 mini to warranty?IF so,how to downgrade the radio version,i have try upgrade the rom and downgrade back,but it's there a way to downgrade the radion version? i am newbie so hope can learn more thing here sorry for my poor english. Have a nice day!

no one can help?

I can help!
The reason why the radio is not downgraded is because the ROM backup actually doesn't downgrade radio at all.
Now, the way to do it properly is to first grab whatever ROM package you want (I grabbed an Imate JAM v 1.01 ship). Then you extract the files in the .exe file to a folder. Delete all the nbf files except "radio.nbf" then use MaUpgradeUt_noID.
Basically, by deleting the other nbf files, you are only upgrading/downgrading the ROM.

nbf file

Okay, I've spent 2 hours trying to obtain this information and am almost giving up.
Where do I obtain my nbf file? I want to change my splash screen but this is proving to be the most obscenely complicated thing I've ever done.
Could anyone post thier T-mobile 2.26 nbf file for me?

search in the Upgrading etc. forum for Wizard, "Cooked Custom Rom How to"

I found that thread and it alreeady assumes you know how to obtain and nbf file. One person gave a link on the ftp for a ROM dump utility and the ftp says that it doesn't allow anonomous logins. I included my user name and password but it wouldn't accept it. Why is this so complicated?
Could someone please tell me how to obtain this file? It's making me crazy. :evil:

Rename the RUU exe file to a rar file and open it, the nk.nbf file is there.Or just run the RUU (but don't click anything) and search your pc for nk.nbf and copy it to a safe location then cancel the Updater.

Thank you so much. In this forum, I read that I was supposed to change it to a zip, which didn't work, this did though.

I would suggest you move any questions regarding this to the Upgrading Forum. That's where you'll get more assistance.

T-Mobile ROM

Does anyone know how to load the t-mobile ROM onto an O2 XDA EXEC.
I downloaded the T-Mobile rom, but because it's an O2 device doesnt recognise it.
Thanks in advance

Extract the T-Mobile-ROM, until you have a nk.nbf file.
Extract the attached file and put it into this folder and overwrite everthing. Now start RomUpgradeUt.exe

thanks for interest but l need the file.in the link you send explain how to do flsh from a crad.l need SD Image file

I think nobody understands what you need the way you are writing...

Every rom has an RUU_Signed.nbh file. This is what you are looking for.
Download any rom, extract is, and you will find the RUU_Signed.nbh file.
