SEUS does use the CDA to decide on what can be flashed. I bet if i have a phone that is completey unbranded generic and has always worked with seus, i change the cda to CDA123456/7
It will work? I think not................ |

I beg to differ, Mr Brooks. 
I (with your help) have proven that the SEUS uses the first digits of the IMEI (the TAC, was it called?) to decide whether it is allowed to use the service. The CDA is not used when deciding this. But, once the phone's been approved, yes, I agree that a CDA of CDA123456/7 would cause problems with the actual firmware part.

same outcome. But the imei thing is a bit dodgey and this is what happens when there is a 3 way conversation and one player does not have all the info.
I claim nothing, but this person has a t-mobile phone - and so for the necessity of speed i have discarded the imei checking. As it was my belief t-mobile phones can use seus?????
By the way, what does TAC standfor? or even the FAC?

@ gbrooks3
To me, it's not the same outcome. There's a difference between allowing and disallowing, and IMHO, that's what the IMEI does, not the CDA.
T-Mobiles cannot use SEUS, so this will be very interesting. I'd love to see if this guy's T-Mobile phone works with the SEUS after he's changed the CDA. I'm sticking with what (I think) I know.
I don't know what TAC stands for, or FAC.

So even i change the CDA to CDAgbrooks/3 and the IMEI is in the database i will be allowed to update? Sounds kinda funny.
About imei,
TAC or as it should be known - Type Approval Code is the first 6 digits in the IMEI. From these numbers you can find out what type of phone you have. For example a Sonyericsson T610 with IMEI begining with 351253, if we find another IMEI starting with that number we know for sure that it is exactly the same phone model that I have. So the TAC is not a unique thing.
FAC, Final Assembly Code - is a 2 digit number that comes directly after TAC, in other words number 7 and 8 in the IMEI number. The final assembly code provides you with from where the phone is made and from which manufacturer.
But this is maybe the interesting part i think. Next we have the SN or serial number. Its set up to how each provider wants to set it up...............................
Of course we have the CD, check digit but i am tired of typing now

What I'm saying is it will be /allowed/ to update, but won't necessarily work, whereas some are completely /disallowed/, regardless of the CDA. I'm not going to argue, because at the end of the day, almost everything I know about this stuff is from you, but it's what I believe based on my personal experience. 
This is why I believe it...
Myself and 3 friends all have Orange K700i handsets. 2 of them are fairly old and 2 are fairly new. All 4 had the same Orange CDA, but the 2 older handsets have IMEIs starting with 35400600, whereas the 2 newer handsets have IMEIs starting with 35401000. Prior to any unbranding, the 2 older handsets worked with the SEUS and the 2 newer handsets didn't.
I unbranded all 4 with SE Tool, using the same firmware, and a CDA of CDA102298/83. So now we have 4 unbranded Orange K700i handsets. And guess what? The 2 older handsets work with SEUS, and the 2 newer handsets (one of them being mine) still doesn't. So I think this speaks for itself.

I understand what you are saying indeed, however the TAC is a phone model thing, i dont think its related to the the operater in any way - of course i could be wrong. It may just be that the SEUS is not updated with that model, i really do not know. When i get a k700i i intend to have a real good look at seus in which i will need your help |

I look forward to it.
The first thing I'll want to know is the first 8 digits of your IMEI and whether your phone works with the SEUS!
