I am running froyo on my captivate as well, and my phone is constantly freezing. When it power cycle it I get a grey battery as well as a spinning circle icon. It will only power on if I plug it in and wait for it to show charging...
Can anyone help me get my phone back to eclair?

Have at it boys

If your phone came with JF6 stock, follow the link in mcord's post. However, if your phone came with JH7 stock, do NOT use the program in that link, or you will brick your phone. Instead, follow this guide:

[Q] where can i find odin?

i see people talking about odin all the time but where do you download it from?
is it part of the SDK?
i am having trouble with my phone, trying to change the lock screen there was an error i'm assuming a conflict with adw or something. well anyway the phone goes into a loop saying a process stopped unexpectedly and and asks you to force stop, you force stop and another pop up for another process shows up. there is no way out of it. it loads up the phone so that i cant try to uninstall anything. i tried to clear personal data and that didn't work. i now think i shouldn't have done that because i dont think there is any way to recover to the backup rom with rom manager.
im gonna keep trying but i fear i might need to flash it back to stock. but i dont know where to get odin and is it phone specific? a link would be super helpful right now
Search my friend, and you shall receive. Its stickied in development.

Got it, although the one click version didn't work, I did however get jh2 working. Now I wonder which mods work with it?...
Sent from my SAMSUNG-SGH-I897
im pretty sure all of them as jh2 is a stock rom
how the heck did you get froyo in the U.S.?!?!??!?!
Read the development section. We have 2 captivate froyo leaks with custom roms built off them and leaks for the vibrant and bell vibrant, and official i9000 roms
All working to varying degrees on the captivate.
Oh and this is an old thread and jh2 wasn't froyo, it was a leaked beta before the jf7 update came out.

[Q] Before I try this 2.2 froyo

I'm completely stock right now with the new update H7 and new to this flashing and rooting stuff. I've been reading everything and seems yall got all this down to just clicking one button and the program does the rest.
So before i try this everyone says backup backup backup soo that leads to...
1. Is there anyway to back up my phone like it is now since i haven't rooted. Just in case something goes wrong
Or
2. is the only option i have is to do the one click root thing and back up the rom then try to flash the 2.2 ?
and
3. If something goes wrong and 2.2 doesn't flash right..could i just go into recovery mode and click reinstall packages and be back to the h7 (if i don't root to back up)? or does that recovery option get deleted/overwritten when i try to flash 2.2 with odin one click?
thanks for any help
You don't really have to back up your phone. It is up to you if you have important info, games etc that you want to keep. Lots of times games were either purchased from the market so they will be attached to your profile. Use appbrain to sync your market as well. Otherwise there really is no way to do a backup unless you are rooted.
so basically i'll have to root to back up the phone at its current state? ...i'm not really worried about having to reinstall everything i've only bought beautiful widget so far but i think froyo flash deletes everything anyways right? but i just want to be able to go back to stock in case something goes wrong and the flash doesn't work or say the phone screws up and i need the warranty.
If the flash goes wrong can i go back to recover mode and hit the reinstall and will it reinstall the h7 i have now back to the phone or will that recovery option be deleted when you try to flash the 2.2?
In rom manager you have the option to back up your phone in its current state. If you get boot loops or continuous force closes you would need to use odin to flash back and do root again to load rom manager. Then you would be able to load your backup.

ok thanks man, ...one more thing does the one click root/unroot work just fine with the 2.1-update1 right? the h7 firmware wont make a difference when trying to root?
That should have no issues with 2.1.
My experience with JH7 to 2.2 became a huge issue when I used Master Clear....
I could not for the life of me get the phone into Recovery or Download mode using the three button press or any other combo of USB battery pulls and button presses.....ended up biting the bullet and using the SDK method which turned out to work flawlessly.......after hours of searching, googling, reading and experimenting.....
I now have two Captivates in Stock froyo mode.

[Q] Bricked phone after JI6/Odin

Okay so, I used the Odin JI6 Froyo flash and everything went peachy. Also installed the OCLF and the Voodoo one from off the market.
Problem is that the root wasn't total/complete and the update.zip was replaced but could not be used in full rooting or something along those lines (I'm not certain).
Anyhow, the phone worked great for the last three days, then this evening the browser wasn't refreshing facebook so I restarted the phone. After the AT&T logo it went blank and it vibrated like a beating heart constantly before restarting again after about 5 minutes, which then made it beat like a heart again etc.
I tried going to the boot screen/safe mode and reinstalling the update.zip (which didn't work because of the failed root), tried clearing my data cache, and then also i formatted the sd card. Nothing.
After that I tried putting it into download mode and flashing Odin, which didn't work. It said it was sending the PIT files but stalled there and never changed. I tried a master clear and it didn't go anywhere either.
Any advice?
You should've read the forums more before flashing and saved yourself this headache. You will need this to flash back to stock.

Dowload Odin and the drivers on the first page of the thread. Install the drivers. Run Odin as Administrator. You need to then remove your SIM, battery and external sd card if you have one. Hopefully your button combo will work to get you into download mode. Next, put battery back in, hold the vol + & - buttons and plug in your USB from pc to phone and do not let go of the volume buttons, do not touch power and you should then enter download mode. Yellow screen with android shovelling. Odin should see your phone, push start on Odin and let Odin do it's thing. When Odin finished and your phone reboots you will be back on stock JF6. While your phone is powered on and on your homescreen master clear with Odin.
You need to read a bit before flashing anything again. One Click Root doesn't work with Froyo, neither does Voodoo. Had you taken some time and read you would know this.
Good Luck, I hope this helps.

I feel your pain. Been there, done that. Although your process of bricking reminds me of a more sophisticated approach....lol....mine was out of total complete noobness.
Question:
1) Can you manually boot into download/ recovery manually using 3-button combo? If so you have hope (meaning your phone is basically "un-brickable").
-Bet that made you feel better huh?
-If you can't use 3-button to go into either modes, then you are in the same boat as i was. Hope you are still within your 30 days, or at least warranty. One way to tell if you can/ can't go into either modes is to check your "Batch #."
a) remove battery
b) look below your Serial Number
c) if your Batch # = 1007 = You are safe
d) Batch # = 1008 = good luck
2) When you say Brick, do you have the unfortunate "Phone (!) PC" screen? If yes, then its a "soft brick." If No, then its a "hard brick." I would start to worry.
3) According to your post, it sounds like you have the Regular Odin and NOT the One click version, correct? If you have regular Odin, i would at least try the One click. Regardless, both versions should be able to get you back to stock (JF6), but we already know how well your current version Odin has gotten you.
If you need help, there are TONS more knowledgeable people here in the Captivate forum than I. They should be able to help.
Good Luck!
1. Yes I can go into download and recovery mode. I've attempted to reinstall the 2.2 off odin but it doesn't take. It is the One Click Odin Froyo, it does not work. The Comm screen is yellow, and the logs just say it's loading the PIT and doesnt ever change from there.
2. I have seen that phone ! computer screen, but I'm not stuck at it. When that came on I held the vilume buttons and the power button and it went back to regular boot up (which obviously still doesn't work).
3. It is the one click. I'm not smart enough to use something that involves more than one click.
Stop trying to flash Froyo. Flash back to stock then master clear. Then go read the threads in the development section of the forum before flashing anything. The fact that you tried to apply Voodoo to Froyo and you tried to use one click lagfix on Froyo shows you haven't read and don't know what your doing. You corrupted something by flashing incompatable stuff, flash back to stock and master clear for now. Read a bit and then flash Froyo.

LOL . I as well. I know enough to be dangerous.
Now, on to business. If you actually read what Rhiannon has posted for you, and click on the actual link itself, you will realize that the version of Odin you are using (yes the one click) is NOT the correct version for flashing back to stock (JF6/ Eclair.....NOT froyo). Remember, if all else fails....."The One must return to the Source...." <-----Plus 9,000 to whoever can guess where thats from.
Obviously your phone falls within the 1007 since you have the Luxury/ Advantage of manually entering Download/ Recovery mode....i wish i did.

Well Said!
Thanks Spartan, I'm guesing too much skimming and not enough reading.
OP when someone says flash back to stock they don't mean Froyo. I don't mean to sound harsh, really I want to help you, but you have to read and follow instructions when you ask for help or it becomes frustrating to all that try to help you. If you want to get out of the mess you are in read my original post and use the Odin thread I linked for you please.

I see you are still on Cog 2.2 B5......dont care for 8 or any of the new ones? Or Sheps? What's your story?
Mine is simple....Patience. lol
I am on Cog beta 5.5 with 2e recovery kernel, I swapped the kernel myself before DG updated. It has working GPS and it is pretty zippy, I am not noticing lag. I was going to flash beta 8 last night but there were some modem issues and people losing 3g. Then 8.1 came out and I read the changelog and it isn't much different from my setup. I didn't go to beta 7 because Tw Launcher was removed and you need that for Kies to see your phone so that's a no go. Shep is using an I9000 kernel and I don't want to mess with I9000. I liike to flash my phone but I need to use it as a phone. I have tried some ROMS that I didn't think worked as well so I stick with what has worked best for me. I have all the mods on it, stock lock screen, battery circle mod, and gps works. I may try AOSP this weekend but I work all week not at a computer and I can't just flash all day. I find that things can go wrong and it takes time to reconfigure apps and contacts and if anything goes wrong it sould take a while to fix and I haven't had time to mess with it this week. I see you are still on 2.1, that is patience. I tried out Froyo and when gps worked for the first time ever since having the phone I'm sticking with Froyo. I am waiting for Voodoo to make ot to 2.2 then it will be perfect.
Also, I forget to edit my signature if i only try something for a day or two. I was on Froyo for a few before i remembered to change my sig.

It's all good. I was just curious, that's all. As far as the 19000, that makes two of us. I tried it, hoping that the voodoo + OCLF combo would work.......WRONG! lol
When 7 came out and i too noticed the TW removed, i thought Everyone would take a plunge into that, since many have complained that TW i/o was just unbearable. Oh well. As far as everything else you mentioned, i feel the same way.

I know you were curious, I figured I would just tell you my story. I froze Tw Launcher with TIBU for now, I've used Launcher Pro for months and didn't wanmt a second running in the backround, i will unfreeze it when I need it. Yeah, I try stuff anf when it doesn't work the way I need i go back to what works. I've been using DG's stuff since SRE and I update when it is a better package for my needs, so far his stuff works for my needs. I want Voodoo though, lol. Sory to hijack the thread, lol.

Again, sorry if I sounded harsh, i am just trying to help you get out of the mess you're in. You can flash Froyo in the future you just need to learn about these ROMS and fixes so you don't have these kinds of headaches. I will stop repeating now. i really hope this works. I know your stressed and wasn't trying to give you a hard time, I just thought you were missing something and I am from NY and we are pushy Let us no if you get it working.
I have made some mistakes along the way too and it was because I didn't read the instructions clearly so I do understand how you felt.

I started it. No worries. I too would love to have voodoo. So far, with stock OS, ext2 + OCLF seems to work for me....for now. Keep in mind that i too would like to have the functionality of a Phone. That was my intention in the first place...lol.

[Q] Something went wrong.

I have been running cognition 2.2 for a while but I noticed that there was a newer one. I downloaded it but took the phone back to stock first. Now it does not want to go back into download mode or even recovery for that matter. I have been fighting with this for hours now. I reinstalled all drivers, and even wiped the phone with a reset. It simply will not go into download mode. Anyone have any thoughts? This is back to 2.1 and I hate it.....
If you flashed back to stock - some phones don't have the buttons enabled (i.e. mine)
I always have to ADB back into recovery then flash away.
So.. if you haven't yet. Get the Android SDK - and try and see if you can reboot your phone using that.
Thank you for your reply. But you have to excuse my ignorance . I'm pretty new to playing with phones. Could you dumb that answer down a bit?
I tried to flash it to anything but it just plain will not go into the download mode. I want to take it back to 2.2 but is there any other way that with odin?
Go to the captivate android developement section and read the sticky, Read Before Flashing. Tells you just what you need to know.

going back to stock ATT ROM/OS

I looked through the forums for this but couldn't find the answer. Hosed Froyo (somehow) and want to go back to ATT stock, then reinstall. Have AT&T Captivate One-Click Root.exe but get a :signature verification failed message so it won't go back. Maybe it's the update.zip file that is corrupted or something, but not sure how to proceed. Used Odion (I897UCJI6-OCD-REV02-Low-designgears_1_.exe) and thought that would take me back to original Eclair/ATT ROM but all that did was put in a fresh version of Froyo...which might be good if it works but really wanted to start from scratch (Eclair.).
Anyway to go back?

Look for the odin thread in development to get you back to jf6. Just make sure you use the one with the three button fix included if you need it.
Wrong odin
http://www.fileserve.com/file/emnCn2j
Provided your build is 1009 or lower.
Can find this under battery
Learn how to use the 1 Click HERE...
Then you will be good to go. Use it to re-flash stock 2.1 or the 2.2 leak.
If you can't get to download mode or want an easy reliable way to always get there. Then just get a JIG like the on HERE...
Why would you tell him to learn how to use odin when his op said he has used it? And why do you spam your jig sales all over?

Always a good idea to keep somewhere on the computer for flashing a new rom. or sending back to att/samsung
Thanks everyone. I will read up on the aboe.
Should have mentioned phone is 1010 version (under battery) and I did get it to go back to Froyo 2.2, which I had read reflashing should be done by going back to stock then reinstalling, and so that is what I was trying to do.
Thought I had backed up my original update.zip for for just such an event but apparently either didn't or can't find it :S
The reinstall/reflash seems to be doing ok...unfortunatly titanium pro didn't back up all my user apps so I'm having to go back and reinstall everything, but I'll eventually get it all back.
Thanks again for all the replies!
