[Q] Samsung Captivate ROM/Rooting Help!

My phone originally came with 2.1 Éclair and I upgraded it with Kies Mini the official AT&T way. Then I rooted it with Shortfuse's SuperOneClick method. I was not satisfied though and I wanted to get Cognition 4.3.1 but later found out that you needed to have 2.1 to do that. So I used Odin to go back to 2.1 and then I rooted my phone again with the same method as before. Then I installed Cognition 4.3.1 with Rom Manager FREE version. When my phone booted up, it had Cognition on it but it was not rooted anymore. I still had SuperUser on it but when I opened apps that needed root like TitaniumBackup Pro, it wouldn't allow me saying I wasn't rooted. So then I tried to root my phone with SuperOneClick again and it would work. It said it was successful but it still wouldn't work. I tried to root it with the OneClick and SuperOneClick and both wouldn’t work. After countless times of failing, I tried using my phone to call someone and it wouldn't let me and would start vibrating every 1-2 seconds. So now, what I did was put it in download mode and used Odin again to go back to my original 2.1 and did a master clear with Odin and a factory reset through my phone, and cognition was gone and all I was left with was 2.1 stock firmware, non-rooted, and I was mad.
Now my question is:
Can your phone be rooted and be running Cognition 4.3.1 at the same time? Is that possible or can I just have Cognition 4.3.1 only and not rooted? Is there a possible way to have both?
If there is a way, can you please give me some step by step instructions on how I can do it?
I understand how to root my phone and install Cognition on my phone but when I installed Cognition, the root was lost. Any ideas would be appreciated please.

Samsung Captivate Cognition 4.1.3. w/ Odin 3 flash
Hey Daniel. I had the same problem & trust me they happen. I went to the tube & found a
3 part vid on cognition install with Odin flash & at first it didnt work for me. So I reflashed to
2.1 stock with Odin & followed everything to a t.....having patience watching the vids. I kinda
enjoyed it & was able to effectively flash my Samsung Captivate to Cognition 4.3.1 that is based
off of froyo 2.2 (by the way). Cog is smooth & fast & works great with home launchers!
Enter Samsung captivate rom & look for the mobile tech vid of Cognition. (older firmware used
in vid but all works the same). My phone is way faster than 2.2 stock and I grabbed a ADW from
the market to change the home launcher and all my buds want me 2 do there phones now!
Just be patient,its worth it. You will glad you were when your phone is better than new.

[Q] Wifi probs after 2.3.5 + root?

The other day, I got a text from AT&T indicating that an official 2.3.5 kernel was available for my Captivate. Great, so I fire up Kies mini and install it over my rooted stock 2.2.
Update goes well, I have Gingerbread. All of my apps remain in place. Re-root (SuperOneClick) and my Titanium Backup works like a charm.
However, I can't get my WiFI to connect to save my life. IT scans for about 15 seconds then shuts back off. I can't even enter WiFi settings manually, because it shuts off and "fail to save" the settings.
IS anyone else having issues with WiFI on the AT&T stock Gingerbread kernel? (No, I don't feel the need to upgrade, since I just want to be able to use TiBU)

I just updated to stock GB and have no issues with Wifi, although I am not rooted. I thought that rooting with SuperOneClick didn't work with this 2.3 stock.

I'll have to check that when I get off of work. That's what I used to root the unit when on 2.2. I wonder if the root just carried through the upgrade?
Anyway, I am probably going to flash back to froyo and update GB again, sans root to see if that helps.

For the life of me I couldn't get Superoneclick to work on 2.3.5, or 2.3.3. I flashed the rooted kernel with Odin.

No questions in General, post them in Q&A.

[Q] USB and radio after upgrade to ICS

Hello everybody,
I rooted and upgraded my T-mobile(US) SGs4G from Froyo to ICS, currently:
model sgh-t959v
firmware 2.3.6
baseband ver t959vuvkj6
kernel ver 2.6.35.7-t959vuvkj6-cl694130
build # gingerbread.vuvkj6
since this upgrade i have 2 bugs:
1. usb(mass storage mode) is not working in my car (read error), worked before OK. it's still working when i connect phone to computer. We got another SGs4g in the family (not rooted, just upgraded to GB), it's stop working in USB mass storage in the car too. Any ideas? could i replace usb driver in ICS or do i need to go back to Froyo?
2. I worked in the building with poor reception of GSM signal, so if phone could not connect to the cell, then even if i go outside later it's still "searching" and could not find signal, so i need to turn phone off/on in order to get signal.
Could it be fixed? again it was OK with Froyo: 5-10 sec and reception re-established.
Thanks in advance.

You don't have ICS. You have Gingerbread. Try a factory reset for your problems.

I did
Thanks, my bad, sure it's not ICS, its GB. And i did HW reset in the begining, do you think it's the number of resets that counts? BTW i did not back up my Froyo, do you know where i can get one?

When did you do the factory reset in relation to your problems? How did you upgrade?
Depending on your answers my recommendation is follow the guide in the second link of my signature. GB is worth having.
I can find you a link for Froyo but it is not as simple to downgrade to Froyo as you might think. You will need to make sure to flash Froyo bootloaders also.

first i did root still with froyo
then updated to GB with keos
did reset, and re-installed all applications.
I did figure out how to "trick" lost connection due to no signal:
turn on flight mode and turn in off. so definitely it's a bug.
still no luck with USB
I know that downgrade to froyo is not easy, and i like GB, this is why i'm asking if there is a way to patch usb driver only
regards

Need help downgrading back to froyo from gingerbread asap :)

Okay so i got my phone (US Cellular Samsung Galaxy S Mesmerize SCH-I500) from ebay and it came with gb 2.3.4 originally and i updated to 2.3.5 then later on to 2.3.6. After doing some homework i want to get back to froyo 2.2.2 but i cant!! I tried to flash back to EE19 via odin and it bricked my phone. Then tried flashing back to EC10 and it worked but what happens is it has no signal whatsoever (baseband is uknown/no phone number) pretty much everything is unknown except the build number/firmware version :crying: I just don't get what i'm doing wrong here guys. Every time i try to make the *228 phone call to activate it, it says phone is in airplane mode go to settings to turn it off to enable connections but it's not in airplane mode!!! I factory reset it took out the battery but nothing works!! Although i was able to flash back to 2.3.4 via odin and root it. But still i want to go back to froyo :/ Please someone help me get back to a working froyo :crying: I would so appreciate this if anyone can look into this for me for i am fairly new to android but i'm getting the hang of it If you figure this issue out get a hold of me anyway you can thanks everyone!!!

Galaxy s2 att help

I have a galaxy s2 that I tried rooting, it sorta worked then it did not. So I followed the instruction to put it back to stock with gingerbread .uckh7,
kernal version 2.6.35.7
The phone seems to work fine. The issue is I cannot put it back to ics which is where it was, I tried reloading Kies, I tried just using the update. Nothing. And the phone now seems to once in awhile go into airplane mode by itself, or to restart itsself.
I would love to root my phone, and have it work well. I know enough about computers to be dangerous I am sure. But baring that I would just like to be able to have it back to where it was.
Thanks for the help.
