I got a Samsung Captivate from someone off ebay. I tired running the update through my phone, but of course you can't. It fails at 50%. So I tried to through Kies Mini. Every time i try to, I get Firmware Version: Unregistered Device. It recognizes what phone it is and it recognizes my phone number. I registered the phone on the samsung website, still nothing. Did soft reset, factory restored the phone, and followed the instructions Samsung gave me for Kies Mini. And I don't know if my phone is rooted or not. I'm thinking that may be the possibility. If it is, how can I unroot it?? This is what my phone says in "About Phone":

Model Number: SAMSUNG-SGH-I897
Firmware Version: 2.1-update1
Baseband Version: I897UCJF6
Kernel Version: 2.6.29 jetaek.lee(at)sep-11 #2
Build Number: ECLAIR

I had to put (at) because xda said i can't put outside links in a post because I'm new?? It is the at symbol though.

I don't know if you can tell if the phone is rooted on not through that. But I would really like to get my phone updated soon. I was really looking forward to the Flash Player and the GPS getting fixed since I travel a lot.

Your phone seems already modified. Look at kernel. That is why you got problem when updating via kies. And i bet that phone is rooted already. Or seller unroot when he/she post to sell and kernel it self, it is not a stock kernel, it is a custom kernel.

Check and see if you are rooted, I don't think you are, download "busybox installer" from the market and run it. Unless you are rooted it will fail.

Not quite sure if that if a custom kernel actually, I'll look it up.

In the mean time look up how to boot into recovery, if it's blue with 4 options it's stock recovery
If any other color and more options that is clock work mod recovery.

most if not all custom kernels come with clockwork so if you have stock recovery it's most likely a stock kernel.

I'm thinking maybe the original owner used odin one click to restore it to stock and jf6 is the way early version and some newer phones won't even run that so it may no longer be supported by samsung?? Just a theory...

it's blue with 4 options. but i talked to a samsung rep and he thought it was odd that my build number only said ECLAIR and didnt have a number. but i guess he was lazy and didnt look into it.

Don't worry it wasn't your fault :). Probably from the previous owner. When u flash some custom roms it can change your product code for some reason. Samsung Mini Kies also checks this before it updates your phone. If one letter is off it won't update your phone :(

well my .02 is: STOCK SUCKS
​

learn how to flash a custom rom and you will have a billion times the performance/options/control than you would even think of on stock. and it would be easier than worrying about using kies.

That just means somebody had flashed a T-Mobile based rom that edited the product code. Check your IMEI in Settings>About Phone to see if it starts with "000" or if it starts with the number 3. If 000 are the first numbers of your IMEI, then you could have a lemon due to a corrupted EFS. I have had the issue myself.

Just an FYI, make sure NOT to post your full IMEI anywhere ever.

A normal IMEI will start with the number 3. EFS is a special area on your phone which stores encrypted info about how the phone identities itself on the network. It is where the product code and IMEI are stored. If EFS is corrupted, your phone will give incorrect IMEI info to the network and eventually you will see bad stuff happen like loss of data connectivity and stuff like that.
