[Q] Help - Rooting Samsung Captivate SGH-I897 w/ Froyo 2.2 Flash - Captivate Q&A, Help & Troubleshooting

I updated to the latest OS Froyo 2.2 on my Captivate using the ODIN3 One Click Downloader.
How do I properly root my phone so I dont have to go back to 2.1 and then reupdate to 2.2?
Any help?
I was going to use the one click root for the galaxy s phones available on this site.
but it said it was only tested on 2.1 Eclair..
Does that matter or can I use it?

Okay scratch this.. i figured it out thanks to you all at XDA
I rooted my phone finally and now it has a lag super bad. Especially when texting..
Will Voodoo lagfix fix that?

Voodoo will help with overall performance of your phone (faster r/w access)
But.. um usually Rooting your phone doesn't cause Lag...
If your using the stock 2.2 update you would've needed to re-root your phone as it would wipe the phone.
Most custom ROM's already come "pre-rooted".

Alright i got it fixed.. im not sure what happened then cuz i updated it to froyo 2.2 using the odin one click downloader. Then rooted it using software from another post. Then it lagged super bad. I used oclf and its working great now. I couldnt figure out how to install voodoo so i just used that instead.

The reality is that no, it doesn't resolve lag
not by a long shot in recent leaks, q&a please.
i9000 froyo made lag worse!!!
I installed it yesterday via kies.
The former version worked perfect for me but the froyo update was real bad!
I can't work with my phone, it's getting stuck all the time.
The EMail software won't work at all.
Maybe i'm missing something but if i could downgrade back to the old version it would be great!

Well if you read all post about it you should know you should wipe the catch, Format the internal sdcard and do a factory reset when you flashed the latest froyo.
All error and strange thing you got is for all bad data/settings you have.
Froyo works real good...

Lol DamianGto. Seriously though, how long have you been working for samsung?
If i did work for Samsung i would not be here and help people to tweak the sgs and make custom kernels.
Many issues on the sgs is user errors. If they read some tread they would know how to deal with it.
I feel its to easy to make a tread or post about things without reading about it first.

[Q] software update question

Two quick questions. First, what was the most recent software update that my phone wanted to install? It wouldn't work on my phone, and I was wondering if it was important. Second, does it matter if my phone is rooted and has the one click lag fix?
Thanks

The most recent update was JH7 which has quite a bit of fixes. The most likely reason why you couldn't install it was because you're rooted with one click lag fix.
The best/easiest way to get the update would be to just install cognition 2.1.6
It has the JH7 firmware along with voodoo lagfix.
id recommend going over to froyo( cog 2.2 beta 8) its much better than eclair....i dont face any laggs whatsoever.....do a masterclean first....

Problem w/ rooting 2.2 on Captivate

I update my Captivate to 2.2 Froyo a few weeks ago. Since then it has taken away my Superuser Permission and.completely unrooted the phone. Every "One click root" hasnt worked... I really just want to be avle to sideload unknown applications. Any help would be appreciated.

stock froyo is not rooted, theres many ways to do it search the forums. Or you can load up COgnitions Rom that is rooted. Go to android dev for the thread on he's rom.

Updating to froyo 2.2.1

A while ago I updated to JPO and rooted my phone. I then proceeded to uninstall the stock version of aldiko ebook reader with my new found root power. I now want to update to the newest version of froyo (JPY?), and I read somewhere that the process is more complex if you have un installed a protected app. Is there any truth in this? If so, what do I have to do different? Also, is the improvement over JPO noticeable?
All help is much appreciated.

Nope, definately no issues, after upgrading the the app will come right back to the phone and you can remove it again if you need.
JPY is undoubtedly much faster than previous firmwares....very noticeable difference, made me fall in love with the phone all over again....

[Q] laggy!!!

my 10 day old galaxy s is very laggy!!! it is rooted too.. can anyone help me please and can someone tell me how do i unroot... i rooted with chainfire's cf-root.. thanks
If you find it laggy now, unrooting it would probably be the wrong step to take, as root is required for the majority of modifications you can do to your phone.
Overclocking your phone will provide you with more performance. I would also recommend checking out Pikachu01's scripts, as they will help immensely. Also, make sure none of your apps are monopolizing your CPU in the background.
I'm sure others will have a ton more advice to give. Tweak your phone to work how you want it and you'll be more than pleased, I guarantee it. My SGS certainly does not lag on me, but it did take a little tweaking to get it there. Good luck!
If you want someone to help you, you need to provide more information. What version of firmware are you currently running?

First of all thank you everyone for your time...
yes my galaxy s is very laggy and im using
Firmware: 2.3.3 (updated by kies)
Baseband: I9000XXJVO
Kernel: 2.6.35.7-I9000XWJVH-CL184813 [email protected] #2
Build: GINGERBREAD.XWJVH
I Know unrooting will make lag more but i want to know a solution for unrooting in case i need my warranty back....
Upgrade to 2.3.6 JVZ here: http://forum.xda-developers.com/showthread.php?t=1102881
Root with Semaphore 2.1.1 JVZ here:http://forum.xda-developers.com/showthread.php?t=1112908
Follow all instructions on how to flash in first link. There are screenshots and intructions on How to Flash. Notes: Use the 512pit file, and when you flash semaphore, put it in the PDA section. Put phone in Download mode, power down completely, and press power, home and volume down.
If you want your phone fast and lag free then you may have to step outside your comfort zone. You will not find a magic app to make your current firmware fast, its just not. The links Ive given you have downloads and info on how to make your phone fast and lag free. The first link will even contain a download of your current firmware. To find out exactly what your current firmware is, including PDA, Phone and CSC, open up your dialer and press *#1234#, write that info down it will be helpful for you identifying what to download in case you want to flash back to stock for warranty purposes.

My friend also said his lagged after rooting, there is a unrooting script
Just download Semaphore or TalonDEV kernel AND Thunderbolt scripts that you need.
Unrooting shall accomplish nothing. You need a new kernel and scripts/tweaks like Thunderbolt has.

I don't think there are to many kernals available for his 2.3.3 jvh. Upgrade first.

NO i don't want to unroot but i want to know if there is a possibility to do it... I son't want to flash other kernels because my phone is 10 days old (11)) i just want it to become like when i purchased it.. thanks you guys for your support and your time...
You won't lose your warranty because of root. Samsung does not care if phone is rooted or not. Just like the others say : download a custom firmware with custom kernel and use pikachus thunderbolt scripts.
This is the only way to help you
To unroot you just have to flash the stock firmware that came with your phone (you can see a list in SamMobile site). Easier way if you just want to unroot is to flash stock kernel (unrooted one).
If you just want to phone to its original state when you bought it. Then power it down. Then hold power, home, and volume up all together. This will put you into recovery mode. Do a wipe data, wipe cache, then go to advanced and select wipe dalvik cache. Then reboot your phone. If you're still not satisfied with your phone then also reformat your internal usb under settings> storage. You will lose all info on your phone so do a back up of important data. This is where root is good because you can use titanium backup. After reset your phone will however still be rooted.... But you won't be even close to unleashing the real full potential of your phone unless you upgrade your firmware and kernals with Thunderbolt.

Gingerbread has always been laggy due to lack of ram. If you want a really good and absolutely lag-free rom, I really recommend that you flash your phone to Froyo 2.2.1 (ZSJPK). It has been the best rom I've used, compared to JVT, JVZ, AOSP ICS roms, and a bunch of other custom roms.
Agree about GB, its best if you remove all the Samsung bloatware and services, and try not to use apps that use up RAM via services.
I use stock jvt with all the bloat removed, a nice theme, and semaphore 2.4.0 bm and it runs very well. I do have to freeze facebook when not in use, but it makes a difference. I also tuned ext4

Well why don't you flash a custom rom, there are plenty of them with amazing speeds and you shud try them, also you can simply use a lag fix like the one from voodoo if you don't want to get into the rome and stuff.
another question guys.. i have 2.3.3.. i tried to update ( through kies) but it says i'm up to date.. because the thunderbolt kernel requires minimum 2.3.4, how do i update it???
