Question about reverting to 2.1 Captivate - Captivate General

I tried searching, but most of what I could find revolved around Rogers firmware.
I have a buddy with a Samsung Captivate on AT&T. He's wanting to install 2.2, and has the instructions, but neither of us can find a reliable way to revert to 2.1 in case he should ever need to. I know with my Droid X I would have to flash the SBF to revert whenever I install a leaked update, but it seems a little different on the Captivate. Can someone post a link or quick instructions on how to revert to 2.1 if necessary?
Thanks.

[Q] How to unroot UTB JH2?

Hey all,
Not that i want to, but i was wondering how if possible, to unroot the samsung captivate. I got it rooted and installed the JH2 rom, but i don't know how to revert if i can.
I see the odin one click downloader to go back to the stock rom, but i don't know if that will unroot and make my phone as it was.
I would also like to know if i'm rooted and running the jh2 rom, what would happen if i click the reset button in the privacy menu of the settings.
It's called a one click tool for a reason. It reverts you entirely back to the original "out of the box" feeling. I'm pretty sure even att or samsung could figure out it had a different rom on it.
Also, rooting and flashing a rom are not the same thing

Hey thanks for the reply.
I know that rooting and flashing a rom are not the same thing which is why i was confused about that one click tool. I was unsure if it would just revert a rom and not a root or if it would do both.
Thanks for the clarification.

Odin will perform a full flash of whatever ROM (the one-click just happens to do JF6 for AT&T) you want. This will replace everything, including partitioning even (that's what the .pit file is, if memory serves). Basically, I'd be willing to believe if you were to use Odin with the JF6 ROM and drop it off at AT&T, they would be none the wiser. You can also, of course, use this tool to flash the i9000 ROMs with our captivate kernel (buggy at best) or even use the new JH2 ROM (as you obviously know by saying you're on JH2).
A factory reset will only put you back to "factory" settings, I don't even know if it will restore missing AT&T apps, but I doubt it. But it will keep you on your current ROM. So factory reset on JH2 will keep you on JH2, while flashing with the one-click tool on JH2 will put you on JF6. Sorry if this is repetitive and long-winded, but I figured any additional clarification for others couldn't hurt
Edit: I should also add there IS a way to unroot somewhere on this forum, too lazy to do the search right now. There's a one-click root/unroot that I believe SHOULD work with JH2.

Haha, i had to read this a couple times but i learned more in that post than i ever knew about these phones. I thank you for that. This definitely clarified allot of questions that i probably would have plagued the forums with.
(sorry if i put this thread in the wrong section, i see it was moved)
Thanks for the help =)

[Q] So I went back to stock on my phone

because I wanted to try out a gingerbread rom and i figured that since I was at stock I would open up Kies to see what kind of update it would say for the phone, but when I looked at it, Kies doesnt show anything. I mean it reads and finds my phone no problem but where it shows "Current Firmware Version" its just empty.
I remember previous times I did it, it would still show Version 2.1 and ask me if i wanted to update to 2.2.
So I guess im asking, if I should be concerned with this?
I did use Odin to go back to 2.1 btw
which odin?
odin3 one click? the ATT one? the one that obviously wouldnt work with Rogers keis?
or odin3 flashing utility with the Rogers Stock roms in my sig?
keis is crap anyway. if you want 2.2 flash my 2.2 stock. but dont bother if you are going to flash gingerbread. avoid 3e recovery, but theres a fix for that too in my sig.

Actually it was yours in your sig. It was the only one I have been using since I found it at like the beginning of the year. You are right Kies is crap but I keep it because id like to give Gingerbread stock a shot once it comes out before flashing to gingerbread roms. But now that I think about it, I think it might be that kies had an update when i opened it since its been so long from the last time i used it. So it was probably that.
And thanks I will look at that 3e recovery before i start flashing.

[Q] Will a Hard reset return an Evo shift from gingerbread to froyo?

Does anyone know if doing a hard (factory) reset on an Evo shift that was upgraded to Gingerbread from froyo (as opposed to one that came with it) will return it to froyo?
I assume someone has tried this to resolve the rooting issue with gingerbread but I wasn't able to find an answer in the forums

This has been mentioned more times than I can count. As of right now there is no way to revert back to Froyo if your running Gingerbread. People have tried doing this many different ways and it's just not possible. Your going to have to wait for a new root solution.
Thanks, I figured it had but I ran some searches and didn't come up with an answer one way or another.

[Q] HELP - Captivate Stuck on 2.1!

OK Ill try to shorten this post as much as I can.
Basically I was running 2.2 Froyo on my rogers (canadian) captivate today. I tried to upgrade to 2.3 using Samsung keis (officially released 2.3 in Canada/rogers). The update did not work at all and I was forced to recover with ODIN one click and it brought my phone to 2.1 (it was never at ANY point 2.1) and AT&T. I need to know how to bring it back to atleast 2.2 so I can try to upgrade to 2.3 again (I think I know what went wrong, I was rooted, probably screwed it somehow). Ive attempted alot of things to try and bring it back including factory reset but I dont want to screw with it any more myself. If anybody could post step by step instructions with links on how to get back to 2.2 short of sending it in (absolute LAST resort) then you have no idea how grateful I would be. I just want to be done with this phone modding nonsense.

[Q] bootloaders

i have a samsung captivate with android 2.2 froyo and i want to go to 2.3.5 gingerbread. found this link http://forum.xda-developers.com/show....php?t=1300843
my question is which should i download with bootloaders or without bootloaders?
kies mini will not update me and even bricked me so i dont want to ever use kies mini again. i have both odin one click and odin 1.7. also have heimdell one click and prefer to use it but cant find a stock 2.3.5 rom that will boot up on my phone. i have downloaded 2 and used heimdell but didnt work. heimdell is just so much easier but i will use odin if needed. i do want a stock rom nothing fancy since phone modding is a little new to me. i have a computer degree but phones are a whole different world lol...

ok the link above isny working
If you are going from Froyo 2.2 to Gingerbread 2.3, you will need a Odin or Heimdall file that contains the bootloaders. They changed between 2.2 and 2.3, and you have to have them to make 2.3 run properly.
I would suggest this UCKH3 one-click Heimdall solution. It will flash everything you need, and you don't have to open anything else to do it.
Just be aware that it won't have ClockworkMod Recovery installed, so you'll have to flash a different kernel or use a one-click with CWM baked in later.
I would recommend flashing the lastest build (KK4) from Samsung. Here is a link to Odin one clicks and Heimdall one clicks with gingerbread bootloaders.
You must have Gingerbread bootloaders to run Gingerbread roms, however they are backwards compatible with Froyo and Eclair so you won't have to flash bootloaders again.
