[Q] Removing root - Galaxy S I9000 Q&A, Help & Troubleshooting

Ok I read a lot about rooting and tried CF-root. Now I figured I'll revert to an older stock XXJPU with pit etc. Won't that remove root and completely wipe my phone? Or do I have to revert to the original 2.2 that came with my phone?

You don't have to revert to the original 2.2 - go for the 2.2.1 (JS5) and you won't even need any lagfix.
Flashing will remove root and will wipe your settings and apps so don't forget to backup.
Enjoy your SGS.

Thank you for your response.
Yea I've flashed it with JS5 now (with voodoo lagfix) and it's very responsive.
I'm experiencing some force closes on certain apps though.. Either way it's the best phone I've used and indeed a very fun gadget.

[Q] Updating to 2.2.1

Hi guys,
I was just wondering, when the JPU (2.2.1) update comes, I would like to upgrade to it from scratch (remove voodoo, hard-reset the phone, etc).
As of now, I have stock 2.2 + voodoo. How do I completely remove voodoo and everything else, and update to 2.2.1 (not just disable voodoo)?
Does the upgrade through KIES remove voodoo?
All I want is a fresh new 2.2.1 phone, as stock.
Many thanks!
Any ideas?

create a disable-lagfix file/folder in /sdcard/Voodoo (/sdcard/Voodoo/disable-lagfix)
and it should disable Voodoo. alternatively you can disable it via recovery. it does the same thing. (creating a file).
when 2.2.1 is out(if ever), Kies should be able to upgrade without a hitch though i've never personally used it.
it's best to remove all lagfixes and tweaks and all that funny custom stuff prior to upgrading if you're aimming to be "clean".

Thanks, but what I was aiming for was a totally clean phone.
Meaning no disable-lagfix folder in sdcard. Just clean, stock phone.
Does the firmware update fix that or is there a way to achieve that?
Unless I'm mistaken, you first need to disable lagfix as described above. After this, you need to flash a new kernel which doesn't include voodoo or another lagfix. If you're flashing stock JPU or any other stock firmware, that will take care of your problem.

[Q] axura question

i have read some good things about Axura RC2.2 CE. so im very interested in flashing it. im currently running cog 2.1.7 is there any reason i couldnt just use rom manager and flash it right now. or should i flash back to odin stock and then re root grab rom manger again and then flash Axura RC2.2 CE? and in the instructions it said to backup with titan just data and apps but not system data, why is that?

The reason why people recommend ODIN first before flashing new ROMs is because lagfixes and other stuff can cause problems for certain users. Usually you can flash directly from another ROM no problem, but like I said, ODIN and most of your problems will disappear.
As for not backing up the system data, you can backup your system data. Just don't restore it as this can cause a lot of problems. There are framework differences, etc. between ROMs especially 2.1 and 2.2 ROMs. Restoring system data will cause FC city in most ROMs.
i just tried flashing and my phone got stuck in some mode where it kept saying stuff about partitioning and my sd wasnt found.. so lame
i backed up my stuff on titan and saved it to my computer ill try again after i root. hmm weird now its not running the zip file..
Did you Odin 1 Click back to stock first?
Never a good idea to flash over the top of another custom ROM as the guy above me stated already.
You always want that "clean slate" to start with to avoid issues like this. Then you can safely restore your applications and application data - but people have problems restoring system data - so I never do.
Odin 1-click back to stock and try again - it should work fine.
i just ended up odin one clicking it to froyo. which im loving right now so ill keep it like this for a bit. when i had reset my phone to stock i tried axura again but it wasnt running the zip for some reason..after im donewith 2.2 ill go to stock and try axura one more time.

Hmmm..
Easy method to ensure success:
Odin 1-Click back to OTA JH7 2.1 ECLAIR Stock (not 2.2 Froyo)
Root using CLShortfuse's Root application.
Then update to Auxura as normal and it should work fine.

I Have A HTC Hero But I'm Pretty Sure It's The Same....
I'm Not Sure I'm Understanding Your Question, But I Think You Want To Get Back To Your Stock ROM & Flash A New ROM Correct?
If That's It?
You Can, But You Don't Have To Convert Back In Order To Flash Another Rom.... Just "Wipe"
System/Cache/Dalvik Cache,
& Install The New Rom!
You Can Always Restore Back To Your Stock Backup!!

No you can not revert bacj to your stock 2.1 from 2.2 using clockwork with a captivate
Can you explain how to wipe system /cache/dalvix cache or post link i googled it but found nothing with step by step instructions. I would like to try this before odin. Also why does it let you create a back up of 2.1 rom if you cant revert back there from 2.2 then whats the point of backing up 2.1 in the first place. Just thought you could do that instead of odin after reading a post which I was going to post the link to here but wont let me cause Im too new.

I do not recommend flashing phoenix over cognition without a flash to stock, but if you want to try, you can.
Cognition uses voodoo. First thing you should do is disable it.
Find voodoo file in your internal sd. Create a folder in side voodoo folder named disable-lagfix. Reboot phone.
Ok its disabled, but If Odin is the best way to go maybe I should try it but just been reading about higher risk of bricking phone using odin. Just really want to try different rom because cognition it smooth as butter but battery life is killing me compared to stock and yes I tried the charging battery to 100 then unplugging shutting down charging to 100, reboot, shut down then to 100 again no help. Anyways if I use Odin does voodoo have to be disabled also.
Pull your battery. Obviously power off first. Under battery is a build number, mine is 1008. Tell me yours
mine is 1010
Odin may be difficult to use. You may want to research your build more. Anything over 1008 is where odin is an issue
What is your base
Settings, about phone, bottom
Damn i didnt want to hear that,Says baseband version I897UCJI6 is that it.
Yes that is it.
Being on build 1010 I an not comfortable with telling you how to proceed. You need advise from someone who flashes with that build. It behaves differently with odin. I am sorry. Search build 1010
Ok thanks for your help, Ill look around
If you've never flashed with Odin one-click before, try this instead to avoid any risk of bricking (very likely on some build 1008-1010 phones that don't run JF6 stock):

Me And several people I suggested it to. But now I have a batch 1009 Captivate (traded in mine because of random shutdown issue).
saved my cappy once
I guess I'm confused...is odin really necessary at all for him? If he disables voodoo lagfix, and clears dalvik cache, he should be able to flash over the top...correct?
I flashed cognition 3.02 direct to andromeda 2.0 via cwr and did not clear dalvik or disable lagfix (since cog and andromeda both enable voodoo)...no problems for me.
Maybe it's different/more complicated flashing over the top to the ROM he wants to go to though...
i897 running Andromeda 2.0

Returning to stock... Questions?

I currently have Andromeda 1.2 on my Cappy and am really happy with it. I've been thinking of upgrading to 2.2 when it comes out tomorrow just to see how it functions - Then, go back to Andromeda.
Basically, I know how to use ODIN to flash the phone, but I always hear about disabling LagFix and some other programs before flashing to stock. Can anyone give me some pointers? Is there anymore to it then just using Odin to reflash (Download mode)?
Any help would be great.
Disabling lagfix is for when you are not flashing back to stock, ie. from cog to phoenix. If you are using odin there is no need to disable lagfix.
You will probably have to use Odin 1-click and Master Clear, but make sure to do a backup a la Titanium Backup and store it on your desktop. Then you can Flash back to stock after Master Clearing. I had a lot of trouble getting back to stock after unlagfixing; to make a long story short just Master clear and save yourself a lot of trouble.
After that I was able to reroot and restore my TiBu backup onto the stock Froyo. There is even already a stock 2.2 Captivate kernel with Voodoo lagfix injected, which has been giving me great lag-free performance, battery life and stability that can't be found in I9000 kernels.

Between 2.2 based ROMs I've been returning to stock via Odin 1-click without master clearing. Am I rolling the dice on having problems?
Is Cognition the stock 2.2 + Voodoo ROM you mention?

You dont need to flash to stock every time. 99% of the time its just an absolute waste of your time as the rom your flashing "should" be wiping everything out anyway.

So could I simply be flashing from ROM to ROM w/o attaching to my PC at all? Would it be lower risk if I was staying w/ the same family of SGS based ROM (I9000)?

I am a bit apprehensive using Oneclick with a 1012 build phone. I've been told to ONLY use Odin3, which has no master clear.

I plan on using the Odin3 (NOT oneclick), but will it do a master clear?
...and to confirm - I don't have to do ANYTHING special to flash back to stock? I don't have to turn off any apps/features? Just simply open Odin, get the phone to download mode and reflash??

I generally disable any lagfix I have before I flash, some dont. Don't take my word for it. Read until you are comfortable doing it.

[Q] get back to stock

Hi,
i have a sgs from optus australia with the following info:
Baseband: I9000DTJP3
Kernel: 2.6.32.9 [email protected] #36
Build: FROYO.DTJP5
i flashed the speedmod kernel following instructions on the cyanogenmod wiki http://wiki.cyanogenmod.com/wiki/Samsung_Galaxy_S:_Full_Update_Guide
i wanted to flash cyanogenmod but it had a signature verification fail, which i now know is because of the recovery version. so i've given up on that and i just want to update the phone over kies to the stock gingerbread.
so, i'm pretty sure i can't just connect the phone to kies and try to update it because it has clockwordmod recovery?
so the question is how do i get back to stock kernel? i think I've downloaded the right firmware (from:http://www.multiupload.com/CH3Y5SAHE2), is it a matter of finding the kernel in that folder and just flashing that back on to the phone? is there going to be any issue with this?
thanks everyone
So I just went for it and updated the phone via kies. It worked with no real dramas.
So the next step in getting back to stock is to get rid of superuser, which I can't do now because the update took away root.
Is there a way to temp root the phone to remove superuser then get back to unrooted again?
Why not to flash with odin, with repartition and full wipe?
It will restore it ot factory settings.

Thank you for your reply, I read this a couple of days ago but I didn't really understand half of what you said lol
So I googled a lot but i'm no closer to understanding. I did a factory reset just from the settings menu but that didn't work. What does repartition do?

Repartition will effectively wipe your entire phone (it repartitions the phone's memory).
Odin is a program used to flash (install) firmwares, both custom and stock ones. Tutorials are everywhere, please search.
Cool thanks for that, I guess the problem I had with understanding is what am I flashing? The stock firmware? Because isn't that what kies just did (albeit without the repartition). Seems like a pain to find the stock firmware since I just got it from Samsung ota

It's either that or you root and then unroot (no idea how to do that one).
http://www.samfirmware.com/ has firmwares. If you flash a Froyo one (repartition checked), you could then update again via Kies. This will give you an absolute stock phone (including the loss of all your information via the repartitioning).
Have you tried going to the market finding the super user app and trying to click uninstall from there. Im guessing you tried the normal way...
