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.

Yeah - I could not get it to work on the phone - so I went with OCLF which uses ex2.
It worked fine.

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

i reached until renaming recovery to xxxxxrecovery. but the problem is i could not see the folder /system/bin when i connect my phone to the computer..gave up...thanks for the help though..
if you can then pls give a little bit more help..i have always dropped .zip files in the main directory of the phone and have flashed custom roms before..this one is difficult for me...
Looks like I will never be able to put voodoo lagfix on my stock 2.2 captivate. Lot of help posted here but none seem to work for me. I may need more detailed step-by-step instructions.

the answer was already given to you....you need root explorer or super manager....this isnt done from your computer.
Is there a way to undo this and put the new recovery back without using odin one click and upgrading again?

The SGS kernel flasher app page in the market says "*lagfix detection is not finished". What does this mean? I am planning to flash voodoo lagfix kernel on my stock froyo captivate. Please let me know

Try Cognition 4, it's about as close to current stock with Voodoo injected. If you really miss any of the apps taken out, Designgears was kind enough to put them in a repository for you.
alright i've been up all night and i have no idea what i did. i guess we'll start from the top.
one clicked rooted
downloaded rom manager
installed cwm
installed bionix frost rom
decided to mess with voodoo
and where it gets messy...
wanted to try out a gingerbread rom, so flashed after a full wipe
forgot to turn off voodoo
now when i try to get to the recovery screen, its all garbled. sometimes it doesnt even come up.
on top of that, i cant mount the sd card anyway. what should i do?
Do not use rom manager use the cmw from krylons post. To install gb you need gb bootloaders. So. Install kg4 leak by chadster than isnatll kg4 kernel than flash your gb rom thru cmw and walla..

I got used Odin to flash that hawk.zip from another post to get it back to stock. I've never really dealt with partitions before, so it'll take some getting used to making sure everything is mounted.
Wouldn't work on my computer and I was up all night trying to figure out how to wipe and flash from adb lol. Feels good to finally get some sleep.
I'll make sure to read guides more throughly before flashing on phones I don't own lol.

when i got the phone i upgraded to 2.3 and now my phone is messing up and i dont feel like sending ym phone to tmobile so is the anyway to re-do this update, or downgrade back to froyo (2.2) ??
You want stock froyo? You'd need to install clockworkmod recovery and restore the stock 2.2 nandroid backup from the development section. If you want, after that you can either keep clockworkmod recovery or flash back to stock recovery.
If you installed CWM recovery you can apply a backed up image of the OTA update then use NVFlash to restore the stock recovery. T-Mobile is shipping the phones as GB now and it is now considered stock. Don't worry about going back to Froyo.
Yea but the only reason y I want to go back to 2.2 is because I can't root on 2.3 for some reason

I have been trying to use Odin with no success recognizing my device. So I am giving up for now.
My question is can I use CWM or rom manager to flash a rom without Odin. I am stock froyo 2.2 and was wanting to flash another custom froyo rom like fasty or similiar. Can this be done without Odin? Thx
Sent from my SAMSUNG-SGH-I897 using Tapatalk
If you don't want to use ODIN you will have to find the method to get around the 3e recovery in order to use ClockworkMod recovery. You'll need something like Root Explorer from the Market so you can move files around. Search in the forums for 3e recovery workaround.
When you get that, then just put the zip of any froyo rom on your internal sd card and flash it through CWM.
This is the most simple type of flashing so if I lost you, your best bet is to read as much as you can about flashing froyo roms. Luckily, it is generally safer than trying to start out with gingerbread roms.

Have you considered giving Heimdall a try?
You may also want to check the options in the "Connection Issues" post in my signature.
That's what I needed to know. I put the 2e recovery fix through root explorer. So I should be in good shape. So I wipe everything, and does it matter what CWM I have. I just installed CWM thru rom manager.
PS I am gonna try hemidall soon.
Thx

Theoretically, if you have the 2e recovery fix done you can flash the new rom from the recovery menu with no problems. The new rom will just replace the old one but all your data will stay where it was.
I would suggest backing up and flashing from stock because most roms run better this way. But, to each his own.
Lastly, Rom Manager sucks for Galaxy S phones. You should really learn how to use odin because there have been some problems when people use rom manager.
Ok just got this phone and have decided to go with Phoenix Blood rom, but how do i start? I have to be on froyo to root? Im coming from samsung epic on sprint that i flashed so im not completely retarded. Thanks for any help
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.
Phoenix blood is a great choice btw, enjoy!

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.

If he wants to change Roms he will still need Nvflash regardless how he gets it rooted.

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.

thanks for the help guys got it all set up
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.
