Updating to latest firmware

Hi. Im pretty new to all this and was just looking for some guidance. I got the Captivate about under 2 years ago and have never updated it? I tried to using Kies but it never worked. Always said that the device wasnt recognised or something. So my question is, what is the latest stock firmware for the Captivate and how can i flash it?
Thanks!

latest official supported version is 2.3.5, KK4 -gingerbread.
you can find links to stock roms and tools for flashing in the stickies at the top in the captivate android development forum.

Hi. thanks for the reply! so i had a look there and just had a few questions. i am currently on froyo and so want to upgrade to gingerbread. do i need to flash the stock kernal? or the bootloader one? and if its a bootloader one, do i need the one with or without the bootloader? also, what does it mean by modems for the captivate?
thanks!

regarding bandwidth

hi all......I flashed my stock captivate to helly bean and my signal is dropping constantly and since I stay in India ....is there any way to get proper signals ?......please help me out ....if I need to change modem please recommend me one ......I was on vibrant before and used kb5 modem which had never run into any sort of problem ........now I'm on i9000xxjvt now ...thanks for helping

Happened to me too.
I initially flashed KG3, but right now I'm using the one that comes with LANIGHT 8.0 (totally recommend that rom btw) it's KC1 I think it works a bit better (might be just my impression).
Good luck!!

I flashed 3 different modems and now I'm getting good signals but .......when I'm calling some one there are saying my voice is not at all clear .....this happens when someone calls to me also but I can hear properly .......I initially taught rom problem I updated to hellybeans latest one and same problem .......its killing me now I'm on my gingerbread stock kk4 modem .......should I Odin back to stock or flash another rom?

If your rom is jellybean, ics, cm, miui, or similar then u need to use i9000 modems for those. See this thread... http://forum.xda-developers.com/showthread.php?p=16843698

I think the stock one is JK4 for JB. But for jamaica, I'd suggest looking at the modems your carrier is on, those would probably be the best.

Ok after doing some research i found out that the network I'm on uses the 900mhz frequency.. which modem uses 900mhz as default?

A modem with 850mhz unlocked would probably do great but what I think would be best is to find the base of your carrier's modem.

Well, JK4 is actually UGJK4. So let's say you have JK3 (UGJK3) and it works great, you know that the newer modem, JK4, will work well.
But now that I'm thinking about it, did your phone come with GB? If so, it's quite hard to us to know which modem is came with. Modems are by area so (almost) every carrier uses different one. There's a modem thread in the Dev section (stickied), you might have to try a few different one.

When i got the phone it was running Froyo which I later updated to GB.. my brother's Cappy has the UCKK4 and he's still running GB.. we got the phone the same time and both updated the same time so I'm assuming that is what I had before I upgraded to JB.. I'm on JK3 modem but i can't seem to flash JK4 or any other modem.. it always ends with an error...

I re-downloaded the file several times and still nothing.. I even changed the CWM and nothing.... I'm on the verge of giving up

U can use Odin3 v1.83 (the regular Odin) to flash a modem as well. Just pull the modem.bin out of the cwm zip of the modem u want, get into download mode, put the modem.bin in the PHONE tab/slot in Odin and flash.
Get the Odin here if u don't have it already... http://forum.xda-developers.com/showthread.php?p=33577757
If u r running a JB Rom, then u will have to use one of these modems...http://soggycashew.weebly.com/cm7miui--ics-modems.html
I have had success with the i9000ugkc1.

No need to give up, you can flash modems after modems without any problem. It just a bit time consuming.
To be safe, backup your efs folder so that if your IMEI is unknown again, you can use the backup.

From what i know of the Captivate specs...the gsm 900mhz frequency that it can operate on is just the 2g/edge network. U said u saw the H before on GB rom (custom rom or leaked firmware, i'm guessing?). That letter H can be changed to read whatever letter u want. Just saying.
So in reality the problem may not be the modems (although some modems will work better than others for sure), it may just be the network service that your provider has in your area... It may just be low/bad cell signal.
What other frequencies are used by your provider ? Compare that with the frequency band specs of the Captivate and you will get a better answer on the quality of service you should expect. Maybe your provider has a coverage map that you could compare to as well.

[Q] CM10 Modem Update

This is on my wife's phone so can't take time to fix mistakes. She has a Captivate that is running Cyanogenmod 10.1-20130416 Experimental Captivatemtd-M3, and Modem T959TLJL3. I believe it's a I9000 modem, what are the newer modems available? Where can I get a copy of current modem to restore if I need too? I have found 2 but not sure they are for this phone/kernel.
Thanks
Ken

See this link... http://soggycashew.weebly.com/cm7miui--ics-modems.html. It is from the Modem stickied thread in the Dev forum.

So the radio-cm7-ics-captivate-tljl3-signed.zip should be the one I have now? Right?
Thanks
Ken

Yep.
And even though it doesn't say it, the modems in that link i posted will work for jellybean as well.

Hey there,
Take a look here
http://forum.xda-developers.com/showthread.php?t=1870460
Because you're in Croatia, XDJV1 might be a good choice for you.
If not, JW4, JVU, ZSJBG (or something along the lines, the actual name escapes my memory, but it begins with ZS) are all good modems- the last one especially, because that (according to others) has really good wifi and connectivity as well as good battery.
EDIT: ZSJPG
Its safe to flash the modem zips through recovery, and you can flash as many as you like to try.
Cheers,
Soryuu
