I used to run custom ROM serendipity 5.11. Decided to give the official stock froyo a try. So, I flashed it to JF6 and installed I897UCKB1 on my captivate. Now, I miss the root privileges and also the stock ROM is still not smooth. There is a big improvement from 2.1 but not there if I compare with serendipity. So, is there any way I can root and install lagfix on my stock I897UCKB1 2.2 captivate? Please help

There are many many threads going on here that covers this. Either get a custom ROM from Cog4 or Torch 1.5. If not then use SuperOneClickv1.6.5-ShortFuse and http://forum.xda-developers.com/showthread.php?t=870760 for lagfix

I tried rooting the phone the traditional way and it tells me the update.zip is not e_signatured (or some thing like that) verified. How do we root the NEW Froyo Stock ROM??
Greatly appreciate any assistance on this!!!

The assistance was in the post right above your own.
The reason the old update.zip method does not work is because Froyo uses 3e recovery, which requires the update.zip files to be signed. The SuperOneClick root bypasses that and directly gives you root. After this you can install CWM, and flash the supercurio voodoo kernel, which gets you the lagfix, and rids you of 3e recovery, all at the same time.

You can install the voodoo kernel via odin, but that can't be done straight from the phone. It is also packaged as a CWM flashable update.zip, so you could do it that way, but you still need a computer to root it first. Without root, you can't get into a non 3e recovery, and without that, you can't flash the package straight from the phone.

Prior to the current stock 2.2, i used serendipity custom rom on my phone. i used AIO toolbox for captivate to flash serendipity custom rom. can i use the same tool to root my 2.2 phone? i am very new to this whole stuff. i see that this particular voodoo kernel provided significant performance improvement on the stock I897UCKB1 captivate. If you can provide step by step guidance that would be great. thanks
I'm rooted and have the 3e problem....i go into recovery with CWM but update fails...tried the 3e patch that accepts unsigned but sbin recovery is read only won't let me delete/overwrite....tried an emu to chmod but says permission denied lol....i must be missing something.... I'm familiar with os but can't seem to figure this. Only thing stopping me from voodoo lagfix is damn recovery file not being deleted

My Infuse is rooted & stock Rom.
Can someone tell me how to install these or tell me if I am fine.
1. Put the phone into debugging mode
2. Run the .bat file

After running the .bat file the recovery is already modded?

I'm not sure how to install this. I got my infuse literally yesterday and I'm trying to learn the ins and outs of installing roms. I tried to replace the recovery file using the manual 3e method but was unscessful. I was hoping to use this installer, but I don't know how to execute it. I tried putting the phone in debugging mode, and going to root explorer but there is no way to open it.

Make sure your in debug mode. Connect it to pc. Run the bat file, wait untill you see success prompts. After its all done, you should see a blinking cursor.

I'm not sure what you mean by this. Are you just trying to get it into recovery? If so, do you have the Android software developer kit (SDK) installed? The SDK includes the adb binary. Download it, install it, then open a command prompt, cd to the 'platform-tools' directory where the SDK installed, insure your phone is on & plugged in via USB, and issues the command: adb reboot recovery.
If I'm off-base with what you're trying to accomplish, my apologies.

Don't use a KFx rom, the KF1 and KF2 versions of Gingerbread were really buggy and will give you more trouble than they're worth. You're better off flashing Octane, Valhalla or ICBINB which get updated frequently.

Which also means that you need to flash a KG4 leak or newer for the proper GB bootloaders. If not, you'll get a rainbow screen.
Similar Problem
Hey Guys,
I had a similar problem. I am using Fire Expert to overwrite the new recovery to the \system\bin folder. However, I realized my mistake was that I did not mount as r/w. After I did that though and I held the volume up, down and power, I stay stuck at the initial splash screen and can't go into the stock recovery screen. I can't boot regularly either; I have to Odin recover. Any help would be greatly appreciated.
Thanks!

Overwriting the old recovery and putting the update.zip file on the sdcard for CWM Final was for Froyo ROMs only, not Gingerbread (GB) ones. What ROM are you currently on?
In order to get into recovery since flashing the GB boot loaders I have to:
Power off the phone
Hold down Volume Up, Volume Down, and the Power button
When the Galaxy S screen comes on, wait a second, it'll get a tad bit brighter. When that happens let go of only the Power button
Wait a few seconds and you should be in recovery
Sounds like you might be a bit goofed at this point, though. If you were on GB before I'd suggest using one of the ROMs in bhundven's The KJ6 Heimdall One-Click Collection. The last one in the list will also give you root, CWM, and voodoo lagfix.

I've not used it but if it allows you to mount /system read/write, then it should work fine as long as you're putting the 'recovery' file in /system/bin & the update.zip on the root of the sdcard.

I followed the instructions and gain root but it doesnt stay. If I do the anything I lose root.
What do you mean "you lose root?" Once you have flashed the Superuser Pack to the phone you have permanent root, it doesn't just "go away" like "poof" it's gone.
However, CWM (Clockwork MOD) does go away unless you load a custom kernel or deactivate (CHMOD to 000) "/system/etc/install-recovery.sh".
I dont remember which app I install but it will say you dont have root even though I just rooted and it said I did,I reboot and clockwork is gone. Now I am having a hard time getting back. Guess I might go back too EE4 take update and go and see what happens from there. Right now Im stuck on the samsung logo after I followed the directions.
Ok I just loaded the ep4d bloat rooted version and it started and will just freeze what I dont want.
Nope boot loop. Gonna check out the other thread then restart everything. oh well
I found that if I use the app Quick reboot and try to go into recovery it removes root.

Use superoneclick to root on froyo.
If your on 2.3.3 gb there's a flashable. Zip in development section to root.
Also you will want to use tgagunnmans nvflash method to install clockworkmod recovery in dev section.

You're still on Froyo? To my understanding it's a good idea to flash the OTA GB first so that you'll get the up to date baseband. Once that's done just go ahead and flash PB.
no im on gb jsut thought i had to go back to froyo to root, so i just flash clockwork mod then pb and thats it?

Yes, but make sure you're using NVFlash to get CWM. Don't use Rom Manager.
Easiest way is using the tool unlockroot. It supports gb on the G2X. Or you can use nvflash, whichever you prefer.

From that thread:
Flashing the custom recovery using NvFlash is the only way to ensure that in the case your phone will not boot up, you will be able to get into recovery to fix the issue / flash a ROM / restore from nandroid backup. That is what this app will do for you.
If you flashed the ClockworkMod recovery from ROM Manager it does not flash the recovery to your phone, it fake flashed it. The only way you can gain access to ClockworkMod recovery is through ROM Manager at that point. Using this method is the only way to flash recovery so it is persistent and accessible booting to recovery.
If you have already flashed through ROM Manager you can still proceed with this method. Flash Away!
(You can use both ROM Manager CWM and have the nvflashed version working together. You just access either or one at a time, having the nvflashed one means you can boot to CWM. Welcome to Tegra2)

Follow the link. This is a must for tegra 2 based phones. It is always better to be safe than sorry and it also allows you to do a ton of other things, such as making backups and flashing roms. Let us know if you need help. The phone is pretty much unbrickable after you do this. It gives you the ability to recover from any major mistake.
Its in the dev thread, it low level flashes clockworkmod recovery to our phones internal memory partition. You need to install apx drivers first in order for the g2x to be nvflashed.

Just to add in, nvflash allows u to boot into cwm recovery whenever u want and u don't need to be next to a computer. I think that is how it worked for Samsung phones and Odin, where u needed a computer, but haven't used a Samsung phone so I could be wrong. Remember always make a back up of everything and play around with the different roms, not every rom works for everyone
Sent from my LG-P999 using xda premium
Actually Odin is just like nvflash. It is used to put cwm on you phone and to put the stock recovery back on.
Once you have cwm you can flash what ever rom or kernel without the need for root. Just back up your stock unrooted stock rom before flashing anything else.
If you do that you will have your own stock backup with no need of finding it in the forums if you need to go back to stock.
