I having been trying to root and unlock my Samsung Captivate and I have constantly been hitting dead ends. I have tried various apps and YouTube clips and nothing seemd to work. I know someone out here can help me unlock this phone. I rather learn how to unlock it than pay $50. I NEED HELP!!!!
Phone Specs:
I don't have AT&T Sim Card
Base: i897uckb1
Firm: 2.2
Kernal: 2.6.32.9
I am new to this "unlocking and rooting" world, so I have been learning while i'm going, please bare with me in advance.
The last program I ran to unlock the phone was "OneClickUnlock." After it went through its whole deal, my phone read - "E:signature verification failed". I have no idea what to do from here...PLEASE HELP ME SOMEONE!!!!
There are plenty of threads that cover both these issues.

what you need to do is read. thats how you learn
i would agree with pirateghost but i find that people do things all @$$ backwards around here and give out the most time consuming ways to do things.
ok you already have the odin one click installer, is that the one the brings it to jf6?
does the phone boot? or does it enter recovery and give you that message?
since setting up adb might be too much too soon the best way will be to get the phone back to a bootable state if it is failing to fully bootright now. if the phone is a newer model and came factory installed with kb1 it is posible that you need a different one click installer, infact dont bother with the one click installers, it is faster to use the full oding to flash a kernel with cwm installed by default.
http://forum.xda-developers.com/showthread.php?t=1007276&highlight=rogers+stock+rom
this is the rogers 2.2 rom, first one i found and better anyway. use the odin and pit and .tar in the downloads in that thread.
select repartition for good measure and flash the the above rom, the .tar goes in the pda slot. the 512.pit goes in the .pit slot, that's all that is needed.
after you flash your phone back to working condidtion, use odin to flash a custom kernel, the kernel must be in .tar format
http://forum.xda-developers.com/attachment.php?attachmentid=547852&d=1300708475
^this is speed mod, maybe the most popular and stable, if the phone will boot into the rom then you can start here.
put the kernel .tar file in the pad slot in odin and flash it in download mode, no .pit is needed.
with this kernel you can flash .zip files. you can root or skip strait to flashing a rooted rom, you may also have luck with one of the att kb1 kernels with modifications like skull cap or firebird if you like the stock rom, which the bluetooth calling needs an att or a rogers kernel and modem to work.
most people arent .tar-ing the kernels they build. yet all the users like to flash to stock before a flash, seems to me since you are sitting at odin, flash a kernel and shorten the whole process.
The reason you get the signature failed is because your recovery mode is a type called 3e the 3e recovery mode doesn't allow unsigned packages such as the unlock. What you need to do is get a kernal that has the 2e recovery mode in it and flash that, then you can root using anything and flash update. Zip files, you will need to follow a guide for that though, you can find one by searching "flash 2e kernal on captivate" in google

I messed up my Bell SGS playing with odin.
Lost the 3 button options and ended up hacking a jig to get it into DL mode. done
Goal - a Functioning phone. Now what?
Thinking I should odin the I9000M_JL2_JL2_JL2_JL2_UG_BMC.tar.
But with or without repartition?
Can I use any 512pit?
I think repartitioning is where i messed it up.
Now all of this happened because I wanted seeARMS.JL2.v0.4 but couldn't update with the <3e> recovery mode.
Knowing that seeArms is my second (first?) goal, is there a different firmware I should flash something other than BMC to give me back update functions, but stable to resuscitate my phone?
There's ages of material here and I don't want brick my phone or waste time, I've done enough of that by myself.. now I'm looking for some expert opinion.
thanks
Best option for bell users is darkys rom. For further info check darky's rom info

So the stock JL2 that I have is a .tar and .dll
I have a 512.pit from a beta 2.2 , are they different?
Did I mention boot problems too? Hanging @ Samsung, no splash ani.
I guess the .pit means yes on repartition?
Thanks
Just use the stock firmware and .pit from samfirmware.com and when Odin is open do not tick off repartirion... just put the .pit in it's spot and the tar in th's PDA part and flash

Download a full firmware for your model and locale (with dbdata in it) and flash it with repartition with the pit proposed (samfirmware.com) then, I believe, you will have a full functioning phone. If everything is ok, then flash ... whatever.
It's Alive! - Can't mount /dev/block/stl10 fixed.
Hey All,
Got it all working again.
Repaired: Can't mount /dev/block/stl10
the fix: A full firmware (pda/csc/phone/pit) flash w/repartition.
Flashed w/repartition - I9000XXJP2.7p. (the only FULL firmware I had on-hand)
on reboot the system does a media check and was successful in reformatting and mounting the internal SD.
Phone didn't like the ROM and still logo of death, but..
A quick Jig into Download Mode..
Flashed I9000UGJL2_homebinary_add_param.tar with no repartition
(can't remember if I used .pit).
And Success!! my phone is alive and running 2.2
Thanks for the help, and hopefully this thread can help others.
Everyone should build/get a jig
There is nothing more awesome than being able to force download your non-booting phone.
I could not have done this repair without one.

Yes, do this. For repartition to work the .tar has to have dbdata.rfs, otherwise it won't work.
Then flash a speedmod kernel with odin for root/cwm and flash you're favourite custom rom
unlock&root owngrade or speedmod kernel? suggestions?
Forgot to mention that all this started after I got the phone back from Bell service after SD card failure.
I know mod methods changed with the latest firmware, as I had used the update.zip method that is now unavailable.
My phone went in unlocked and rooted
the phone came back re-locked (old code doesn't work? wtf?),
and it was unrooted w/3e recovery
Can the phone unlock code change?
Will downgrading to 2.1 make unlocking easier?
or is unlocking just as simple after a speedmod kernel with odin for root/cwm
Which is better?
downgrade the firmware to 2.1 and root using the old update.zip method or speedmod kernel?
Which kernel? (link please )
cheers

You know what....I've been trying various combinations of CSC/MODEM/PIT and everything to get this phone running again.
All I did was select a FULL UGJL2, and thats IT. NO pit, NO repartition, and it worked
The best way to revive your I9000m is to first flash JPC (a three file ROM) with 512 PIT and repartition ticked. The phone will still be in a boot loop. Then flash the JL2 PDA without repartition or PIT. The best way to go back to stock! Has always worked for me. I9000m's are not the same as other I9000's and do not flash repartition and the PDA in the same flash! Good luck!
How did I permabrick my cappy?
Flashing with Odin, I restored to the Rogers stock 2.1 firmware, however the phone refused to boot past the rogers loading screen. I re flashed the phone a few more times playing with the flashing options of Odin, using alternate stock .tar files with no luck. My final flash caused the phone to get into such a state that going into download mode no longer worked, as well as it failing to boot. Luckily Rogers warranty has replaced the phone for me
Any ideas on what caused the phone from booting into the OS, so I don't do it again?
Additional Questions
1. The new cappy given to me through the Roger's warranty has stock 2.2 loaded on it. Is there anyway to back up this firmware to a tar file for later use? If so, how can I use it in conjunction with Odin to restore to stock 2.2?
2. Do I HAVE to restore the phone to 2.1 eclaire firmware before loading a custom ROM on it? Or is it possible to root / reboot into clockwork recovery and successfully flash from stock 2.2 froyo?
3. In my past experiences, after restoring to Rogers 2.1 stock firmware through Odin, kies no longer recognizes the firmware currently loaded on my device... Is this normal? Any fixes? Is there anyway to get kies to recognize the firmware such that it would be able to upgrade or even wipe the phone with the standard stock firmware? I ask this because on the new kies I see the function "emergency firmware recovery".
did you brick flashing the NEW stock 2.1 thats in my sig? or the old one that messed alot of people up in a few ways?
#1 yes but unsure how to make, it would be used like any other tar and odin.
#2 from what ive seen sofar, 2.1 wont boot on phones that came with 2.2, but it was a noob i was talking to that had the issue. the only thing you run into is having 3e recovery and needing the fix before you can load clockwork on 2.2. all is good from there.
#3 normal. no fix. keis sucks

Thanks for the link! and the prompt response
Are there any .tar files floating around for the Rogers froyo 2.2 that address the warranty / logo issues? (search function seems to be broken).
Any stock 2.2 rogers .tar files for use with Odin floating around the board?
What is your recommendation with regards to proceeding with flashing? Should I try to flash 2.1 on the phone with 2.2 preloaded, or just go the 3e clockwork recovery fix route?
Any other pieces of reading you might be able to point me towards in this regard?
I would suggest adding your locale to your profile for future reference, as restoring an I896 is different than an I897.
There is also another way to get clockwork on your phone.
Use Odin and just flash the speedmod kernel .tar from here: http://forum.xda-developers.com/showthread.php?t=893880
I have done it this way since I got my phone and have yet to run into a problem. This works with 2.2 only.
2.2 odin flashable (NO ATT boot fix) and cwm upgrade from 2.1 zip. are here
http://forum.xda-developers.com/showthread.php?t=905042
the person i mentioned before that couldnt get my 2.1 stock to boot on his 2.2 ... he did fix the att boot by un-successfully flashing my 2.1 then the 2.2 overtop, then it booted correctly WITH the i896 bootscreen, basically double flash.
i will contact the creator of the updated 2.1 and see if he can do it to 2.2 as well.
feel free to attempt to flash 2.1 to confirm weather or not it does work on a phone that comes with 2.2. as this isnt confirmed. also note any new notes on the 2.1 stock rom page.
oh and speaking of the updates on that page...
theres the fix for the getting stuck at rogers bootscreen on first boot after flash... (the problem you had)
reboot into recovery and clear data and cache, reboot. done.
sorry its late...

That's common. Everytime I flash the gf's Galaxy Spica, that's the first thing you have to do with it is clear the data and cache. I just do it instinctively now.
i'm trying to figure out how to just get to where i can flash a rom, my phone is sgh-I897 running 2.2 froyo.uckb1
if i have read some of the stickys right i need to use odin to flash back to stock or flash a different kernel is this correct? to get around the 2e-3e sig.verif.
could someone please point me in the right direction? from what i can tell there are alot of ways to do this or maybe not??? which is the safest or shortest..
thanks to any that can help me out.....
Yes, you need to get past the stock 3e recovery before you can do anything.
Method 1) simple, easy. Use the script from the 3e sticky in general section (post 3 from TRusselo) to patch from your computer. Then you can flash CWM (through update.zip or ROM manager on the market if you are rooted), and flash any number of FroYo ROMs. NOTE: you cannot flash a GB ROM from FroYo.
Method 2) kill fly via sledgehammer, possible risk, and 3-button problems later depending on build number of phone. Put phone in download mode (power off, hold volume up and down, plug in USB) flash via Odin back to 2.1 stock. (Different Odin will fix 3button if you know it will be an issue) then flash CWM, and flash FroYo ROM desired. Odin *can* brick your phone if something goes wrong; cable unplugs, battery removed, etc.
Im sure there are more ways, but those are the most common and easiest.
Recovery is in the kernal, so a new kernal will fix, but you have to replace or mod the 3e recovery before you can flash a new kernal.
My suggestion is the windows script file, its easiest, and can't brick your phone.

this is false. you can flash a kernel in ODIN and completely bypass 3e recovery altogether.
there are several kernels that are ODIN ready......
Read the before flash posts, then read them again. It will save you a ton of headaches down the road. And almost every rom has step by step instructions-read these next.
Please search before opening a new thread. All of this is in the threads. On a side note. A fast way is not the safe way, and the safe way is not fast. Think about what you are doing, do you really want to rush it?
So, just switched out my captivate because my warranty was still in effect. Rooted etc etc. But I remember installing CWM with rom manager to begin flashing my first rom back in the day.
But anywho, I have installed ROM Manager, clicked to flash CWM but when I go into recovery (vol + - & Power) All I get is the samsung one. (Blue text) and I only have the options to reboot, install packages, clear cache or wipe sd card.
Can anyone offer any advice?
^ Try reinstall packages. U may have to do it twice.
Gotta install the update.zip with install packages but you have signed bootloaders if you're on stock froyo. Odin to 2.1 and install cwm from there. You can find the update.zip for cwm on the cappy forums and just put that on the root of your internal memory to avoid using rom manager. Don't even have to root to flash.

^ If u want to go back to Stock Eclair...use the first link in my signature below.
I typically use Odin jf6 one click rev0 from designgears. Its still on the forums I believe but might be dead link. Just make sure it has the pbl and sbl. If you are worried I can upload the one I have used for the past 9 months without fail( but ffailure is always possible, just be sure to follow directions and you should be alright. ) alternatively there is a guide to get to stock jh7 on the forums using the Odin that you have to manually select files for. Should be an easy search. I believe people consider this safer for the newer builds but I used oneclick on my 1010 tons of times and have used it once on my 1012 no problems.

What Odin/One click package should i download to get root with GB bootloaders with CWM and flash zip file roms only? So i can flash roms like Fasty III and others? Which one is suggested for great battery life? Experts please
First off you don't need root to flash a rom. as for bootloaders use either a leak 2.3.5 i897 rom with bootloader or just the bootloader package. They are stickied in Dev section.
Can you please send me a link im new at all this but im learning i have Odin 3 v 1.81 and Odin v 1.81 ATT GB bootloaders extracted. I just want to be able to use download mode jig and plug in USB and go.
I have UCK H3 one click is that good enough to get started? Could i flash a rom in rom manager like fasty III im looking for fast and grt battery life.
KH3 1 click should be good. Don't use Rom Manager. Here you can find everything you will need. Just flash KH3 or any other GB leak, let it boot up normally, flash (with ODIN or SGS kernel flasher(app)) the boog's kernel that has CWM, let it boot up normally. Boot up in recovery and flash the rom.
Yea ive seen this which one should i pick and with or w/o bootloaders. 2.3 or 2.4.5 not sure? Just want the best one for speed and battery life and i like launcher pro.
I don't use launcher pro so can't say. But IMO KH3 or KJ3 would be my best (I still use KH3 modem). You need bootloaders so you can flash one with bootloaders.

SGS kernel flasher requires root. Which rooting involves a kernel swap with Odin anyway, so for this purpose its pretty useless.
I just flashed UCK H3 and while in process i checked flash bootloaders now im soft bricked. Will the download mode jig help? I have one i dont know what to do. It doesnt work. What can i do am i screwed? I have the soft brick symbols on my phone now.
Reboot pc, swap usb Ports (make sure its one on the back of the PC), right click Odin and ruin as admin, put .tar in pda slot, Pull battery, replace, use jig, ignore screen that appears, connect to PC if Odin recognizes it hit start.
Grt thanks ok i got the fish now what do i reboot or what and add kernel next? I still have Odin opened and USB plugged in
Disconnect, close Odin. Pull battery, replace, use jig, flash boog's kernel the same edu you flashed the fugu kernel.
Im getting a screen that looks like a TV screen all lines what the heck is that? Its boots to ATT logo then TV screen all colors and lines. I did the kernel it passed but not sure whats going on now. It keeps rebooting ATT screen and TV looking screen
... That sounds like you didn't flash correct bootloaders. Correct me if Im wrong. On a side note ya Studa I had a brain fart on SGS kernel flasher.
I can still get in download mod with jig. Cant i try a diffrent package in Odin?
Did you use KH3 with bootloaders?
Not sure what to do im trying the AIO toolbar and im enabled for root phone but seems like nothing is happeneing im still in download mode
that is froyo boots on a gingerbread ROM.
op flash this package
That will flash the gingerbread bootloaders which will get rid of those lines and make it possible to boot into recovery.
DO NOT USE AIO TOOLBOX AFTER THIS PACKAGE IT WILL BRICK YOUR PHONE. might as well just delete that for safe measure.
Ok i was in recovery in rebooted phone now im at ATT screen logo no lines now. What do i do now is there a rom to flash or am i even rooted? Can i go into download mode and flash a kernel
Im staying at recovery till i hear back from someone lol. Where do i go from here?
