Hi, thanks 4 the reply.

Had you flashed the lower secure mbmloader before?

Status code (Locked 0) :/

@pedrotorresfilho: Secure version is a plain number. What I was describing is signature type (different column).

And no, once you have cdt.bin with sec. ver 03, you can only flash another one with sec. ver 03.

Oh, Man!

Actual official OTA to Vivo is GB 2.3.5, but update to 2.3.6 before ICS rollout is about to happen. Next one will probably be the good one. (All the OTA updates to LatAm razrs came from service providers, carrier: Rogers, Fido, Telcel, Vivo...)

I saw a VIVO update news in motorola website and I'm guessing ICS will come first to vivo phones.

Thanks a lot!

Bump!

But yours if perfect!

To someone who prefer to get their hand dirty,

Open the cdt.bin with a binary editor.
Main secure version ID is at 0x37FC (value = 04 since ICS)
Certificate is 2048bit, starting at address 0x3800 ~ 0x3FFF
Customer ID is at 0x3FFE
-CID 7 : EU XT910
-CID 5 : SKT XT910S
-CID 4 : CN XT910/KDDI IS12M (XT909)
-CID 2 : VZW XT912

#CID for LATAM? (I haven't check)

Extra:
Remember the method to install chinese ICS??
by wiping the CID partition, the bootloader ignores this end bit &
that enable you to flash different region rom.
The side effect is, it's only bootable via bp-tools.

I'm a motorola noobies & my information could possibly wrong.
Proceed at your own risk.

Attached is a simple Java command line tool (usefull for batch job)
usage : java -jar cdt_reader.jar input.bin > output.txt

Thanks for sharing!
I have a bricked xt910s which has no sbf files to flash...
My question is if i change the CID in other razr version's fastboot files cdt (to match my xt910s), would i be able to flash it to my damn SKT Razr?
Would it be possible to edit that cdt file?
I greatly appreciated your suggestions!
Thanks.

The cdt file is sign by a Motorola security certificate. If you edit it, it will failed the verification test. It won't be flash-able.

No need to change hardware parts. They are able to flash special signed fastboot files to rewrite partitions.

Of course it's possible they'll check partition signature to find out you void warranty.
