JI6 to Stock JH7 - Captivate General

I flashed FROYO.UCJI6 (i know this is an old ROM received back in october 2010 with some bugs!) using odin one flash method on my samsung captivate which was running JH7 firmware (which I upgraded from at&t out-of-the-box firmware JF6 through samsung kies program). Now, I am planning to downgrade my phone from FROYO.UCJI6 to 2.1 JF6 (i found the 2.1 JF6 firmware executable file online somewhere) through the same odin one flash method. My questions are:
1. After I downgrade from FROYO.UCJI6 to 2.1 JF6 using odin one flash method, can I upgrade it to 2.1 JH7 through samsung kies mini (the latest kies mini program on my windows 7 64 bit computer?
2. After I upgrade to 2.1 JH7, will I be able to upgrade to 2.2 FROYO if that ever becomes available for samsung captivate?
My current 2.2 is way better than that ECLAIR 2.1 JH7 but it is still not official and contains bugs that are annoying sometimes. Can anyone please guide me on this? I am new to the world of xda and I appreciate any help. I am also very new to the world of this whole ROM flashing thing and I consider myself an amateur at best. PLEASE HELP.
Regards,
Antony

The answer is YES. You can keep using Kies Mini to upgrade to the official 2.2 when it is released. I'd stay away from OTA upgrade. And Kies Mini will be faster way to do it anyway since you don't have to wait for your turn from OTA.

If you are willing to flash leaked froyo, why not try a custom rom. Most are already better then what the official froyo release will be, if it ever comes

I'm thinking of rolling back as well. Mainly because I could never get the market fixed with the leaked 2.2. There's a ton of apps I have to side load from my wifes Captivate and it's getting tiresome. Plus my battery life is atrocious with leaked 2.2.

Thanks a lot for the reply. Have one more dumb question. Can I upgrade straight from JF6 to 2.2 through kies? Or do I need to have JH7? I thought any version lower than 2.2 would do. If I am correct then I can keep working with the released froyo and switch to JF6 on the day samsung/at&t release an official froyo update. Please confirm my understanding. Thanks once again

correct ... you always have the option to Odin back to stock ... just download odin and keep it somewhere safe on your computer for a rainy day

Thank you. I will if I don't get to receive an official froyo in a month (an official release is possible given the recent update of kies mini) Now that I have taste for unofficial stuff, if I don't like the official froyo then I will try all the custom ROMs out there.

Official Captivate Froyo

After rooting and updating to leaked froyo
Will I be able to upgrade to the official update?
Is there a chance I wont be able to?
Sent from my SAMSUNG-SGH-I897 using XDA App
You can just one click odin back to stock and you will be able to. I believe there is no way you wont be able to unless you brick your phone of course
Not trying to scare u but I don't think u would be able to. I heard once u root and ur files have been messed with, u will no longer be able to ever update. Not even if u flash back to stock. This happened to me with the update they recently released.I researched why my phone didn't update and came across that info. But I could be wrong and why would u want to go to stock?
Sent from my SAMSUNG-SGH-I897 using XDA App
Above info is incorrect. If your rooted you can still update. If you kernel hoped you need to flash back to stock to do the OTA update. I have tested this.
So its safe just so as long as I flash with Odin and don't brick my phone right
Thanks for helping me out with this

the JH7 update for 2.1 eclair......the ONLY update that has come through OTA from ATT
just a thought, why would you want the official update as it will be made so much better after the guys here fix it. then just odin flash it... just my thoughts
happy captivate user cog 7.0 froyo.....
i need to go up to 9.1 but im happy as it is.
I was wondering the same thing. I have a rooted captivate running froyo and I wanted to install the update that was suppossed to fix gps. I erased the root and flashed back to stock eclair and I still couldnt install the update. I spent hours on the phone with att and samsung and did a bunch of factory resets and still no luck. Samsung said that the only thing left to try would be to send it in to them so they could flash their stock os back on it. But then I would be without a phone for a week and they wont give me a loner. Its really frustrating. The only reason I would go back to stock is if they fix the gps issue. That is the only major complaint that I have with this phone.

nobody knows. stop speculating
For the the last JH7 update, I flashed back to JF6 stock via odin one click, then pulled the OTA update via Kies Mini. Since it worked last time, why won't it work again? Once you flash back with Odin 1 click, Kies Mini sees the phone as fresh out of AT&T store. And the phone in such a condition is most certainly able to be updated straight to Froyo.
I just flashed back to 2.1 through Odin and did the update through Settings/Software Update. No issues.
Alright sounds great
I think I might root and get a new rom today
Any suggestions?
Thanks for the help

I was just reading about att updating issues. Came across something that worked for me. After that gps update I wasn't able to check att for updates anymore. So all I did was go to manage apps, filter to all, go to divice manager, delete data, reboot, and I was able to check for updates again. But fyi, I'm not rooted, so not sure if this will help or not.

You will be able to update, however it will most likely have to be done with Kies.
My phone was rooted and like you all would not allow the OTA update when trying to do so through the phone.
I updated kies itself hooked my phone up and installed the latest update. When doing so though, it removed my root access, reinstalled the bloatware, and undid any changes I did that required rooting (like the circle battery mod).
So updates can be had if you are rooted, it just may always require using the POS program Kies.
noone really knows about ota but probably. kies and odin should still work regardless.
the jf7 ota was not a full rom, it was a small file that contained scripts that replaced modules if i understand it right. froyo probably will need a full install and is more likely to work but is not garenteed by anyone, its all speculation. it is not clear that the last update failing was the intentions of samsung or att, they are not intentionally denying people the update they are just not going to go out of there way to support modded phones when they can save space time and data doing another way. people have reported that kies works and designgears is very fast to release odin versions when new updates are available.
Ahhh the GPS. I was in the car with my family last night and me and my brother have Captivates and I had to ask my mother for her 8GB 3GS so we could GPS our way. So sad. I absolutely love my Captivate to death but it Froyo doesn't fix the GPS I will, 100%, never buy another Samsung phone again. I don't care how awesome they are.
I'm going to wait for the update to be released and for a cooker here to make an awesome rom with the official release.
if you have a rooted and flashed phone why would you want the official update just get it from here, I don't see why this is a cause for concern

Custom rom vs att official update

I installed a 2.2 custom rom, now att sent me a txt that there is an update for my phone, should I update?, will it brick my phone?
There's 300000000 other threads about this. For the majority if your not completely stock att will tell you to update

Do not run an update while on a 2.2 custom rom. It is most likely not the froyo update and rather a 2.1 tweak. If you tried it probably would not take, if it did it would probably screw up your phone. If you really want to try the update I would do a odin flash back to stock. If you do not know what odin is you can find it in the development section

ok,thanks ....i wont update since I dont have a data plan , and I know ATT will screw me over.....btw custom 2.2 running great
Either it:
-Won't work, or
-It will work
I'll let you decide which is worse.

Words of wisdom
I wouldn't update if I were you since it isn't 2.2 yet. You'll end up just installing a custom ROM again.

JF6 or JH7

Can someone give me the link where I can get the original stock firmware (JF6 or JH7) for samsung captivate? I flashed my phone with the old leaked version of froyo and planning to get back to out-of-the-box state. Looks like samsung will release an official froyo update soon (this time it was on engadget and pulled later. But I think the release should be sooner). Someone please help me with the link where I can get the factory firmware. Thanks

[Q] ODIN and ATT update - what is this?

I was using a custom ROM. In order to upgrade the rom, I used one click odin to restore stock. Then I did a master clear and checked the version of the kernel SW:
Firmware 2.1 -update1
Baseband I897UCJF6
Kernel 2.6.29 [email protected] #2
Build ECLAIR
This was all expected. Then I checked software update. To my suprise, it said there is a software update. I decided to get the update. It downloaded it, and in the process of installation, it failed exactly at 50% mark. I tried it several time, all with the same result.
Now, the question is what is this update? and why is it failing?
Can someone check their never altered stock captivate if the SW/firmvare/kernel version I listed above match with your captivate.
Thanks
It's been said that once you flash using Odin, even though its Samsung stock, that it will not, or not likely to, update properly.
Its jh7 update
will fail everytime

Did you try an OTA update or did you try to update with Kies Mini? The update that AT&T is sending you is JH7.
If u want jh7 u can still install via kies or cwm zip

I tried an ATT update. Previous post mentioned that it will always fail. It seems Odin is not returning the phone to full stock state. Not that I plan to go to stock ATT att the moment, but is it even possible now to go to stock ATT, with enabled updates?
Or using custom roms is a one way street, that we will never be able to go to full stock with succesful updates from ATT?
2.2 will be via kies and I suspect any further updatea will be as well

Just use Kies Mini...
Kies-Mini
Download Kies-Mini
Install it on your computer
Start Kies-Mini
Make sure your phone is set for USB-Debugging
Hook USB cable to phone
Hook other end to your computer
Kies should see your phone
If Kies can see your phone, UPDATE it to JH7
After Kies is finished updating your phone will be @ True Stock
If that dosen't work get OTA JH7

It is full stock but those OTA updates only work if its being pushed any new captivates will already have the jh7 so att isn't pushing it anymore. Your phone knows its out of date but it can't get the full package anymore
Sent from my SGH-I897 using XDA App
It's jh7, I don't think 2.2 will be out soon. I was at at&t device support center today. I talked to one of the reps about most problematic phone they have met and we talked about captivate a little bit. He said google released it really early and samsung finished their revise really quick, its just att can't take such a huge amount of data transfer at one time. And att is building up 4g network, less attention will be put on 3g than before.
Sent from my SAMSUNG-SGH-I897 using XDA App
You should just stick with custom rom's. The updates you are trying to get are already on 90% of the custom roms and the custom roms have alot more advantages with barley any disadvantages.
The only reason I look forward to the 2.2 release is so we have captivate specific source for froyo I will never again have a stock captivate even if they give us gingerbread next week

All three of ours failed the first time they pushed it and my brother just got a captivate from best buy a few weeks ago with jf6 on it so at that time there were still some old builds floating around.

I was wondering the same lol. I rooted and flashed to Firefly a few weeks ago. I'm tempted to try this just for fun, then prob flash later to the newer Firefly... So just to confirm, using Odin to go back to stock should allow us to get the bloated AT&T update if we wish?
Should I try an ota update before I unroot or will that get me fired?

You WILL need to unroot before you can OTA. We ran into this issue when JH7 came out. If you have root, no OTA. It's even in question if you have flashed a custom ROM/revert back to JF6 stock, whether or not you can OTA. Personally I was never successful at get OTA to update JH7.

Just out of curiosity, why would you even want to go back to stock, after running FireFly?
When the OTA for JH7 came out I was not able to update after I flashed back to JF6 using Odin. It would error out
I had no problem with the jh7 ova update so long ago. I haven't flashed anything yet, just rooted. I checked for updates while rooted & it just said no updates yet. I won't ruin anything if I just try it will I?

I flashed leaked UCKB1 (w/lag fix and a few other tools) because I wanted Media Hub to work (I travel frequently and like being able to easily DL and watch movies on my phone). The Media Hub .apk does not seem to work on any of the other ROMs. It appears Samsung included some sort of DRM support in this ROM that allows Media Hub to function properly.
I'll happily flash something elese when the devs release a compelling ROM based on UCKB1.

Media Hub works fine on Andromeda 1.2.
I'm hoping for the usb audio they promised back when I bought my desk dock. Oh yeah, and the voice dialing they promised when I bought the phone. And of course, the support for the audience chip. I'm sure these will all make their want into the custom roms once they chefs get their hands on the source.
