Can't Seem To Root My Captivate

Hey guys. I flashed to I897UCJI6 (leaked 2.2) using ODIN with no problem. It didn't require root to work so I didnt root. Now I want to go back and root to remove the AT&T bloatware, but I can't seem to root.
I tried the One-Click version but it didn't reboot my phone as it indicated it should. So I decided to do it manually.
I renamed the root file to update.zip and placed it in the main directory, turned off the phone and rebooted into recovery mode. When I went to reinstall packages however it says:
E: signature verification failed
Installation aborted.
Any ideas?

That is due to 2.2 not allowing unsigned files. There are a few threads about it. Do a search for rooting 2.2 and it will lead you to,what you want to know

You're exactly right. I'm using 3e instead of 2e. What's the best way to revert back to 2e? This kernal flashing stuff seems tricky.

I thought of using the CF-Root but my build is FROYO.UCJI6 and apparently I need to have either JPH, JPM, JPK, JP6. So I can't use it?

Have a look here. I found it by searching what I suggested you search for

In all honesty unless you love the leaked 2.2 I would just go the route of flashing a rom. I remember 2e is a bear to root correctly. It will probably end up being as much research/time to root it as to install a rom

Put this on your internal SD card along with your ROM of choice. Reboot in to recovery and install packages 2 times. The second time it will be in clockwork recovery and you can flash your ROM.

I just had the same problem after doing countless ROM flashes in the past. Perhaps its something in their server preventing the download of CWM? Anyways, thanks for the .zip. Worked like a charm!

yes thank you very much for that zip u saved my life well appreciated

Keep that .zip on your HDD and you can bypass Rom Manager (and all the associated problems) altogether.

I have my phone rooted and unlocked. It's the AT&T Captivate but I'm using it on T-Mobile. I've had no problems so far with it.
I downloaded Clockwork's Rom Manager (v3.0.0.7) and tried to Flash ClockworkMod Recovery to begin experimenting with ROMs.
When I click on that it tells me "An error occurred while downloading your recovery."
I have over 4 gigs of memory left and I have 3 bars on 3g and WiFi going. No internet connection problems (i checked the net using market and using the browser, it works fine.)
What else could be causing the problems.
I'm just wanting to get a good stable rom going which ditches all the junk AT&T put on the phone.

Read the above solution...

I Can't get the update.zip file to work. After I reinstall packages is says E:Can't open /sdcard/update.zip (No such file or derectory) Installation aborted. I've tried it probably 20 times today with no luck.

Thank You
Nothing like flashing to find out it wasn't working. Thanks for making my day go better.

Noobie Mistakes
Just like everyone in this forum I'm having the same problem, I followed your instructions posted, but every time I reinstall packages in recovery mode a whole list of new problems comes up..... see below.
---Install from sdcard---
Finding update package...
Opening update package....
Verifying update package...
E:failed to verify whole-file signature
E:signature verification failed
Installation aborted.
PLZ Help.......
Thanks

i have been fight this same thing for 2 days. im going to try the update.zip he posted i hope it works

if the update.zip is already on your /sdcard/ then there is no reason to try and download/flash clockwork recovery.....thats what the update.zip IS

thats what i thuoght but not true. even goin in normal recovery and selecting to install packages gets a error some about no such directory or something even though updat.zip is there even fix permissions gives a error

I'm having the exact same problem. After reading the development section I have decided to flash a custom rom from my stock rom. Installed "Rom manger" from market, then tried to run the "recovery" got the same error msg. Also uploaded the update.zip to my /sdcard the I got the below errors:
E:failed to verify whole-file signature
E:signature verification failed
Installation aborted

Did you flash back to stock JF6 first not JI6?

try this cuz this is what i did and the update.zip worked just fine for me
1. one click back to stock jf6
2. master clear
3. root with galaxy s one click root
(after the root there should be an update.zip in your sdcard)
4. replace the update.zip in the root of your sd card with the one here posted which is the clockwork recovery one and if you want while u do that you can throw in the rom that you want to flash in there as well to kill 2 birds with one stone
(i will re post the update.zip for cwm just in case)
5. power off the phone and boot into stock recovery and hit reinstall packages two times
6. you should now be in clockwork mod recovery and can now flash the rom of your choice
this is what i did and everything went smoothly but this is just me if this helps someone else plz let me know if this works for you
p.s. i will make a video if needed just ask

Try This
After flashing back to stock do a master clear from Odin3
Put update.zip onto internal sd
Boot into recovery
Reinstall packages
After boot enable USB debugging and mock locations
Get Rom Manager from market
Start Rom Manager
Flash ClockworkMod Recovery
Flash away

You guys are making it harder then necessary, the update zip I posted is the clockwork recovery MOD, just flash stock, reboot into recovery and reinstall packages 2 times and you will be in the green clockwork recovery then you can install zip from sd and choose your ROM you placed on your internal sd card. No need to root every again as long as you keep this update zip handy.

I too am having problems with Rom Manager. I just wanted to change modems. No go. So I used the power button to go into Recovery mode, picked the modem file, flashed it then told the menu to reboot system.

[Q] Can't get into CWM

This phone is giving me nothing but troubles as I attempt to install a new rom. I finally got Stock KG4 gingerbread installed and then rooted it, but now I can't get it to boot up into CWM. I have the update.zip on the sd card, but when I boot into recovery it goes straight to stock. When applying the update.zip from there, I just get a signature verification failed error.

Flash Dr. Honks KJ1 kernel with Odin then try installing your rom thru CWM thats the easiest way I can think of .
http://forum.xda-developers.com/showthread.php?t=1194032
thats the thread since CWM isnt working for you do it through Odin

That method is for Froyo only. You can flash drhonk's KG4 kernel that has cwm/root/voodoo lagfix or use one of bhundven's one clicks. I suggest the SMS KJ6 (beta2d) Kernel Stock Rom with Bootloaders one-click as it'll get you on the KJ6 platform with a KJ6 based kernel with CWM/root/voodoo lagfix.

The old 3e update method that worked for Froyo doesn't work on UCLB3 Gingerbread.
To do what you want to do, you'll need to flash a custom kernel with CWM recovery already included, or use the third package listed in step 1.) at this link.:
http://forum.xda-developers.com/showthread.php?t=1613523

thats what im using? just wiped and tried again.. but its still taking me to android system recovery <3e>?
how can that be possible if i odined a package that has cwm?
doesnt make sense?

ok.. i figured it out! i used sgs kernel flasher to flash entrophys dd, worked!

Only the third choice of those three packages has CWM recovery. If you didn't have it, you were using one of the first two packages in that thread. Good job, though, for getting it through SGS Kernel Flasher.

i swear i did.. i even redownloaded it and tried again when you told me to.. not sure what was going on? i should have had cwm.. not sure why i didnt?
but problem solved, all good now! just installed emancipation, since im familiar with the collective! seems pretty good so far.

[Q] Soft Bricked for the past 3 hours... need phone. Help this N00B

Last week I successfully rooted, unlocked my bootloaded and loaded the touchwiz 4.1 ROM. Because the GPS wasn't working and some other fairly bothersome glitches I decided to flash a different ROM, wanted to try CM10. Unfortuneatly, I didn't "read carefully" and just jumped in, trying to replicate my past success by following similar steps. So I booted into recovery to wipe and begin anew.
I used the native recovery, which I've now seen was a bad idea and should have used CWM but I don't know how to install CWM now because I can't load the OS. I originally used Casual to root and help me install 4.1 touchwiz on my Verizon GS3. After factory reset I attempted to install CM10 from the SD card and got the below mentioned error. My phone is stuck. I can only access the native recovery or ODIN mode (I have a mac so I can't use ODIN and Heimdall doesn't seem to want to play nice. Please help!! I need my phone for... life. I'm happy going back to stock if I need to but I'd love to run CM10.

I'd say your best bet is to get all of the ODIN parts and see if a friend has a PC with windows on it you can use for a bit. I dont know of another way.

As far as I know, you will have to flash stock image back with Odin, I don't think anything is ready for the Mac yet. I will be glad when it is, I have 1 as well.
If you don't have any other options, use Boot Camp and Odin will work fine.

Thank you all. Using a friends pc and Odin I was able to flash 4.1 touchwiz but I wasn't able to flash a recovery and keep root.

Now that you have a working device, reroot, install cwm from play store and then make a nandroid backup and flash away. Also,be sure to back up for imei . happy flashing
