Captivate unbrick guide with jtag? - Captivate Q&A, Help & Troubleshooting

Hello, i have a huge problem with a galaxy captivate. Neighbor brought me that phone to flash it because it was acting funny. I tried to use Heimdall to flash it but as soon as it was flashing the kernel it failed. To my surprise the phone got bricked in front of my eyes because of that. I know the Heimdall rom i was trying to flash does work because i flashed a Cappy yesterday with it. But i guess something went wrong with the laptop that bricked the phone. I have always flashed phones using Odin without a problem but, things happens sometimes i guess. Anyways, my question is if someone knows about a guide to unbrick via JTAG for that captivate. I own a RIFF box so if it helps i would appreciate.

I know I saw somewhere a small explanation on what is soldered. But in all honesty is easier to apply UBM.

UBm? Sorry for my ignorance but what is that?

By the way Puertorro, thats a nice flag lol....

UBM Jtag requires soldering 6 small points. UBM (if I understand correctly) is making a jumper between 2 spots. Can't say for sure, I've never attempted neither, my soldering skills are no where near close to do them lol.

Okay, found something in the forum. Will give it a try and ill let you guys know how it went at all.

Yeah thanks, found the thread. I work with a solder iron every single day and i have the equipment. Thanks buddy for your help... Appreciate that

Well, its late at night or early in the morning however it might be said lol.... But im happy to say that the Captivate is alive and running again. Thanks for all your help and those impresive tools that you guys are able to develop.

what problem did you have actually? I think I bricked my friend's (like you did your neighbour's lol) captivate. It was actually 2.2.. I used Odin to flash it back to 2.1 JF6..everything went well..and the Odin also showed 'pass'..but it won't reboot..it boots..shows the at&t logo..then boots again..and it repeats..can't go to either download mode or recovery mode..tried many combinations of buttons..but of no use to that phone..
what should i do?

Now you are soft bricked. That phone is probably a newer build number and dislikes JF6 1 click.

[Q] Bricked Phone PLEASE HELP!

Ok guys, clearly I'm new to all this. I've only had my Galaxy S (I9000m Bell) for 3 days now and already managed to brick it.
So here's what happened, I wanted to flash CM7, what I did was rooted obviously, I unlocked since I'm with Rogers and the phone is from Bell. Installed Rom manager, titanium back, Terminal emulator, Astro, etc. So I'm pretty sure I have the required tools. I also flashed SpeedMod Froyo [K13D HPCall VoodooSnd4 SharpnessFix STABLE].
Alright so I noticed I couldn't boot into recovery from CWM even though I flashed it using Rom Manager, I tried fixing this for a while with no luck. I then came upon a thread discussing the 3 button combo fix for download mode. I wanted to get this done just in case what happened happened lol
So anyways, I couldn't find instructions for Mac so I tried putting the pieces together using terminal and Heimdall.
The last thing that happened to my phone was that I was able to get into download mode using adb reboot recovery.
However continuing to the next step to apply the fix wouldn't work for me using heimdall, it would just fail.
Being the idiot that I am I decided to exit in terminal, closed heimdall, turned off the phone and turned it back on and guess what...yup I'm screwed. It's bricked.
Now the problem is I don't have 3 button fix, so I can't get into download mode (even if i did, i wouldn't know what to do).
I read about the jig fix but I don't know if i have any other options, hopefully something faster that I can do myself instead of buying the jig and having to wait for it to **** from ebay.
Sorrry for the longgg post and hope anyone here can help me! Thanks
PS. I tried using terminal again to get to download mode like i did the first time (adb reboot recovery) and it didn't work...it said no device found or something like that
Hi It seems your only option short of looking for a repair shop or sending phone to Samsung is to try the JIG. If you don't know how to approach this print any of the diagrams or guidelines e.g. look here.
What you can do is go to electronics part shop and ask for help with the jig ask the man to wire the resistors to the pins in usb plug just to see if the phone kick starts if not, well you're screwed.
If it works just buy it if not, google for repair shop with Riff Box and JTAG adapter for I9000 it takes about half a bell to do it (repair I mean). But if it's new you have to return it in for repair.
I guess you should get the jig one way or another, either visit electronics parts shop, ebay-it
hope this'll help somewhat.
cheers
If you're in the vancouver area, you can swing by and use the jig I made
Thank you both for the feed back.
@Tony I'm actually in Ottawa. I found someone on Kjiji that also made his own but wants to charge $10 and he lives too far away so I just went ahead and ordered one off ebay for $9 with shipping.
I read on the xda thread regarding the JIG that it the phone doesn't boot at all and just shows a black screen with the bricked image (as opposed to loading the carrier name or samsung with a white screen before) that it won't work and that is my case. Anyways I hope it works, just gotta wait and see I guess. I just don't even know what the next step would be. What do I do once I'm in download mode? :S
EDIT: NVM about the whole white screen, black screen thing, it says that the JIG should work if I see the PC-Phone logo which I do.
Three days huh? Wow, when you do it, you really DO it. Reading your description it sounded a bit like a Med student doing a brain transplant.
First I would just take the phone back to your carrier or service center and say you have no idea what happened, pay the money and have them sort it out. I fear there is no easy way out of the hole you have dug.
Next you should spend a few hours reading as much as you can here and then start small. Ask questions before you do anything. Root the phone. Try a few different kernels and lagfixes. Maybe flash something from doc's kitchen or a custom ROM. Make sure you know in advance what could go wrong and how to handle it, as much as possible. Once you have some experience then try something like cm7, which is very much a beta on the sgs and quite complex to flash and set up.
Spend a little time walking before you run (no matter how much you think you know) ...you'll enjoy the trip more.

Haha I can't take it back to the carrier, I bought it off kijiji, it's from Bell and I'm with Rogers. I unlocked it and as far as I know Bell is really bad with their warranty and last time I bought a Blackberry that was locked to Bell and unlocked it I was told by Bell that I need a receipt, which I obviously don't have. I would rather throw the phone away and buy a new one than have to deal with carriers.
I'm just gonna try the JIG I guess since I already ordered it. Hopefully doesn't take too long to get here.
And yes, I definitely need to read more and follow the instructions on a Windows PC instead of trying to put bits and pieces together and try to get everything working on Mac.
It seems however that the more I read the more I get confused, is it just me or are there so many different ways to achieving the same thing?
Anyways, I bought this as my first Android to experiment and learn on and so far that's what I've been doing. I'm not afraid of running into problems, I'll try to enjoy fixing them

You are right that there are different approaches to doing the same thing...often it is just a matter of what works for you.
Once you have a jig you will have no trouble going in to download mode. From there anything is fixable using odin. I would suggest reading the thread about darky's resurrection ROM which is a good place to start from when you have had trouble.
Just remember to do your homework and enjoy the process.
Good luck.

Sounds good, will definitely keep that in mind. Thank you for your help, very much appreciated.
Hey guysss!
I just wanted to let you all know that I am a biggg IDIOT! LOL
So I ordered the JIG from ebay and on my way home I went to a couple of electronic stores to try and buy those resistors because I wanted to make my own JIG as well. Anyways, all the stores were closed and my friend told me he can grab the resistors from his lab tomorrow (engineering students lol)
I obviously don't want to wait till tomorrow. I came home and decided to take out the phone from its box again. This time I did the 3-button combo but in a different way, not using volume UP + DOWN + power but I came across a Samsung PDF explaining the Anyway JIG and it showed to press Volume Down + Home button + Power.
I gave that a try and voilĂ !!! I'm back in download mode! YAYYY!
I'm afraid to turn it off or pull the battery out cuz I don't want to risk ruining it even more so I'm gonna go ahead with rschenck's suggestion and use Darky's Resurrection Rom!
Thank you all for your help!!
Uh oh...one last problem
So as of now I am able to access Download Mode but not Recovery:S
Any ideas?

If you can get to download mode you are fine for the moment since that is what you need for odin. Follow one of the guides for using odin here at XDA exactly, and good luck.

Ok so after download mode, I followed the steps to reflash stock, i downloaded the same JL2 that I had prior. Odin said passed but the phone wouldn't boot, it would just get stuck on S in the boot screen...
I did a complete wipe data/cache through recovery and that didnt help.
I then thought I would give Darky's Resurrection a try since it wipes everything anyways...odin again said PASSED but there was a sign of a circle on the screen and it didn't boot. I did it again, said passed again and this time im on a endless boot loop. It turns on says samsung i9000, etc. and then blinks and does it again.
I am still able to get into download mode. I just don't know what to do anymore
Download mode = Yes
Then download stock firmware from samsungfirmwares.com not 2.3.3
or from link
http://forum.xda-developers.com/showthread.php?t=846913
Download ODIN
Flash stock firmware through Odin with pit 512 and repartition checked .
If that fails try Eclair firmware 2.1

Ok so I did the above instructions and I the same happened. I am on JL2 now but it wont pass the boot screen (Stuck on the S). I did check repartition and 512 pit and pda.
I also have this error:
Can't mount DBDATA: copy default media content failed
My question is if I try eclair will I lose 3 button fix? From what I was able to gather the 3 button fix for Bell I9000M only came out with JL2.
Will I lose it or is it permanent once I have it?

if it wont turn on. it is a hard brick. j-tag fix only.
congratulations! your phone is under 1 year old!
you have a warranty! Use it!.
Just say " It just stopped working "
if it cant turn on, they cant prove you wrong!
or get ahold of " mobiletech videos " he just got set up with jtag un-bricking. and the first people to test it out get it done for free!! shipping included!!

Just to add to your post;
If you get any sign of life (light, vibration or any kind of image) then it's not bricked all you'll need is a JIG (you can build one for very cheap).
If that's not the case.. Well back to Trusselo's post
my suggestion is to try this first:

A JTAG is a module that will shoot the boatloaders in your phone. It has to be plugged directly to your phone's board so I suggest you get someone weith experience to do it.
I know that AdamOutler (sorry if I miss spelled) from Team Komin (A3) and Connexion2005 were offering JTAG services for free (for testing purpose). I this point, you have nothing to lose. Your phone is indeed bricked.
Here's a nice thread that will explain what happened: http://forum.xda-developers.com/showthread.php?t=1049294
ohh ok so what if i install a 2.3.3 form and flash cognition are my files corrupt?

Depends.
how did you proceed?
I mean, you can use the 2.3 boatloaders on 2.2 ROMs but you need to flash back to stock using Odin. Even then, it doesn't always work and you've a good chance of bricking your phone.
EDIT: Thx Studa.. was typing too fast lol

Odin one click replaces both bootloaders bro.
To keep the gb bootloaders you use full odin with .tar files that don't contain ANY bootloaders.
omg i feel slow its it the phone or the battery?
strate answer please
The phone.

			
				
Cognition contains the sbl.bin (secondary bootloader) you flashed directly from gingerbread so now you have a gingerbread boot.bin and a froyo/eclair sbl.bin.
In short completely bricked.
Jtag debricking is your only out.
Ok i just got my RMA phone and thats the last time im romming
Thats the risk you assume when you try flashing roms when you have apparently done little to no research...

If all you get when you put your battery in out is a black screen and the keys on the bottom do not light up, it is hard bricked. I did it on friday. Took it into warranty center. They swapped battery and same result. 10 minutes later I walked out with a "new" phone.

[Q] Bricked And JIG is not helping

HI,
I am from INDIA, few months back I got a Samsung Captivate , Till now i tried FIREFLY and CM7 ROMs . The first time flash i did it with ODIN i guess i did it with a wrong firmware ,So was stuck with AT&T screen boot loop issue. Searching the forums and found JIG may help and so made a JIG (as i can't get one here) . and recovered my phone and flashed stock and then FIREFLY and 2 weeks back i flashed CM7 for getting Gingerbread and not likeing the UI of the ROM tried to switch back to stock and then customize on my own.
So When i tried flashing Stock the installation was success the screen stuck few moments on AT&T logo and i thought it would go off, But as i was very eager to get my phone online again i pulled of the battery to restart manually (Which i dont think was nice idea ) Now the screen remains black even i use the JIG to get into download mode. But the phone heats UP when i plug it for charging on computer or directly to switch
HELP NEEDED as i am very addicted to this PHONE
I have the same issue. I was tryint to load Cognition and it just gets stuck on the ATT screen but I haven't tried a jig yet. I was wondering if I can replace the files on the phone with good files that aren't corrupted and see if it boots up because droid explorere can still pick up the phone and so does Odin but when I do a master reset nothing happens.
@rajasekhar - Have you tried: Removing all parts (battery, sim, sd) let it sit for a few min (my preference is around 10 min to insure no residual power is left in the system) then hold the jig in place and putting the battery back in? Keeping the jig in place, so that as soon as the device gets power it is immediately seeing the jig, before it can try any other processes.
A bit difficult to do with hand made jigs I know. If you still getting nothing then your in for the worst and the phone need a JTAG or service center visit.
Tho it sounds a little odd that it could boot up to seeing the AT&T logo, but does not respond to the jig. Might even be a hardware problem.
@i3oots - Since you say your still getting PC response your safe to try and reflash it or just pick something different altogether. Tho you might wanna let ODIN settle and just sit there doing nothing for a few min, w/o then w/ the phone plugged in. Or learn about Heimdall and go that route.
Would I be able to flash it even though it get's stuck on the ATT screen? It won't go into download mode. I'll look on the forums how to flash it too. I'm a newb at this which is why I bricked it but everyone has to start somewhere lol.

You have probably Hard Bricked your phone. A JIG will not work to recover the phone. If the phone has any life at all, then the JIG will work. Else, u hard bricked it...you should never remove the usb cable when flashing bootloaders or odin or anything!
the only solution is to get a JTAG which can recover hard bricks OR you can go to a warranty store (don't know about india) and make up a sob story and have them replace it..

Does your computer recognize the phone? If odin is open, does the box turn yellow when you connect your phone? Make sure you have the right drivers. I think cm7 and captivate drivers are different. Keep trying with the jig. Just because you can't see anything on the screen doesn't mean the phone is dead.

If your phone is booting up far enough to send out USB info for ODIN and other PC programs to see it, then your still in a workable condition. This also means you can still get into download mode, but since things arn't working properly it will be harder. Depending on which bootloaders your phone has will direct which methods you'll have to try out to get into download mode.
AFTER you've had a chance to look around the forum and self-educate on the different ways of getting into download mode. If your still having problems give us a lil more info of what you were running before the flash and to which version of Cog you were trying to flash.
Did anything worked for you, if not only a jtag can help you looks like u hard bricked the phone.
Hi guys
@DaNarki : Yea i tried that method to .
Thanx for ur suggestions guys .I really squeezed through xda for all possible ways of unbricking but no use. SO thought JTAG was the only option.But wanna know more about JTAG???????
Went for a samsung service centre they said they wont handle other country products of samsung. Just yesterday went to the local Cell phone Repair store , He said like he would try using a Ctool box they have for installin onto the rom directly. So i thought why not Give a shot to it ...
That store guy raised another question in me . Yesterday after giving it in the morning he said to call in the evening . I did so and he said the Phone is booting on the Ctool but it is sometimes throwing error . I dint get his intention in saying so . have to go to him today
bricked maybe not
I thought I was bricked also ...HARD BRICKED......no buttons no nothing ...tried odin on, phone plugged in, and hold down volume up and down and reinstall batt......nothing worked.......but this... it worked for me........ok first of all remember this will be a bit tricky because you will have to keep the volume keys pressed the whole time till you have download mode......should also have full batt......take out the sim and any flash cards you may have in the phone and the batt.....set the phone down and watch a couple hours of tv or try to brick your buddies phone so he can feel your pain...lol something.....ok now after your tv show has gone off turn on your computer and start up odin one click to stock.... put just the batt in the phone.....if your friend is still there you should try this with 100% batt.... use his phone to charge your batt.....any way put the batt in the phone....plug the usb cable into your computer......now for the tricky part .......press down the volume up and down now and do not let them go till the end of this and you should have download mode.......now plug in the usb to your phone IF YOU HAPPEN TO GET DL MODE HERE THEN GO AHEAD AND LET GO OF THE VOLUME BUTTONS AND FLASH YOUR PHONE ....if not... KEEP THE BUTTONS PRESSED.......now take the batt out of the phone.....keep them pressed......unplug your usb cable......keep them pressed.... restart odin...... keep them pressed....plug your usb cable back in.......keep them pressed... re-install the batt.....you should get download mode.......remember you have to keep them pressed... JUST... the volume up and down pressed through the whole process nothing else....This worked for me and I was dead bricked no nothing from any of the keys no nothing..... I DIDNT INVENT THIS METHOD I READ IT ON HERE SOMEWHERE AND CANT FIND IT AGAIN......It did work for me when nothing else did.....so if the person that posted it reads this THANK YOU...... ................................................. I hate to say this but I may have got the last two instructions backward you may have to put the batt in before plugging in the usb cable.......Like I said I cant find the original post

If you just wanna know a bit about the process ask this guy. He is pretty much the only person in the US (I know not all to useful to a person in India) that does JTAG for the cappy.
I can tell you this much, it requires a special device called a Riff box and it sends boot info directly to the chip on the main/mother board that is used for the booting process.
Somewhere I've seen a site that listed info of ppl around the world that will JTAG, but I can't seem to find it right now.

I thought I was bricked also ...HARD BRICKED......no buttons no nothing ...tried odin on, phone plugged in, and hold down volume up and down and reinstall batt......nothing worked.......but this... it worked for me........ok first of all remember this will be a bit tricky because you will have to keep the volume keys pressed the whole time till you have download mode......should also have full batt......take out the sim and any flash cards you may have in the phone and the batt.....set the phone down and watch a couple hours of tv or try to brick your buddies phone so he can feel your pain...lol something.....ok now after your tv show has gone off turn on your computer and start up odin one click to stock.... put just the batt in the phone.....if your friend is still there you should try this with 100% batt.... use his phone to charge your batt.....any way put the batt in the phone....plug the usb cable into your computer......now for the tricky part .......press down the volume up and down now and do not let them go till the end of this and you should have download mode.......now plug in the usb to your phone IF YOU HAPPEN TO GET DL MODE HERE THEN GO AHEAD AND LET GO OF THE VOLUME BUTTONS AND FLASH YOUR PHONE ....if not... KEEP THE BUTTONS PRESSED.......now take the batt out of the phone.....keep them pressed......unplug your usb cable......keep them pressed.... restart odin...... keep them pressed....plug your usb cable back in.......keep them pressed... re-install the batt.....you should get download mode.......remember you have to keep them pressed... JUST... the volume up and down pressed through the whole process nothing else....This worked for me and I was dead bricked no nothing from any of the keys no nothing..... I DIDNT INVENT THIS METHOD I READ IT ON HERE SOMEWHERE AND CANT FIND IT AGAIN......It did work for me when nothing else did.....so if the person that posted it reads this THANK YOU......

HI,
I am from INDIA, few months back I got a Samsung Captivate , Till now i tried FIREFLY and CM7 ROMs . The first time flash i did it with ODIN i guess i did it with a wrong firmware ,So was stuck with AT&T screen boot loop issue. Searching the forums and found JIG may help and so made a JIG (as i can't get one here) . and recovered my phone and flashed stock and then FIREFLY and 2 weeks back i flashed CM7 for getting Gingerbread and not likeing the UI of the ROM tried to switch back to stock and then customize on my own.
So When i tried flashing Stock the installation was success the screen stuck few moments on AT&T logo and i thought it would go off, But as i was very eager to get my phone online again i pulled of the battery to restart manually (Which i dont think was nice idea ) Now the screen remains black even i use the JIG to get into download mode. But the phone heats UP when i plug it for charging on computer or directly to switch
HELP NEEDED as i am very addicted to this PHONE

Hope it helps I wish I could find the original post again to thank the guy that told me how to do it. I had sent that phone back to att and the promptly sent it back and told me the water dammage sticker in the bat compartment was missing and they wanted to charge me 409 bucks for the phone ....long story short it was there when I sent it and I told them to go pound sand up their ass because I wasnt paying them that much and ended up paying 125 bucks for a paper weight.So that is when I decided to have it jtaged but figured I would give it one more shot before mailing it off. That was when I found the post from that person and low and behold it worked........................... I hate to say this but I may have got the last two instructions backward you may have to put the batt in before plugging in the usb cable.......Like I said I cat find the original post

Buddy tried it ... Thanx for that..But dint help . Now going for another options i mean in search for other options
But ppl help me with JTAG thing and its users(or developers) availability in india
Forgot to mention
I Missed to explain my flashing procedure i have done this time . Like I never tried flash a boot file along and so was reading some threads about boot loader variations between FROYO and GINGERBREAD so i tried flashing ablong with boot loader and then I got the stock gingerbread file i put the boot loader SBL in heimdall Firstboot loader path .And Boom the first reboot got stuck and i removed the battery and then again when i tried to restart the phone is dead
Thinking this might have where the whole thing went wrong and made the cell dead .

HELP! Flashed Wrong Kernel Stuck at Galaxy Screen on Boot

Ok I have a stock KB2 Cappy. I used Odin to flash back to 2.1 KB1 JF6
Then I used Odin 3 to flash a kernel so I can put on CM7. I am now stuck in the Boot screen.
I have no 3 button, I cannot get into download mode (my jig is homemade should i order one?)
I tried to change usb and remove the sim card to try odin again to get back into stock.
Nothing seems to work the only thing is my jig is not good either for DL Mode. I want to get back to stock so any suggestions. I tried heimandall did not work either.
I am really stuck on this galaxy s I897 screen.
Is the jig soldered? If its not make sure you are connecting the correct pins and use some black tape or something to isolate your fingers from the resistors (might screw up the actual ohms making it to boot up normally and not in to dl mode.
The bootloop was expected, you are supposed to check that you have a working button combo both before you flash the kernel (because it will bootloop and you boot into recovery and flash whatever) and before you ever flash cm7 because that is the only way to get into download mode besides a jig on aosp roms.
so, fiddle around with your jig some more and if you get it in download mode just flash the captivate gingerbread bootloaders, that will fix your button combo and allow you to proceed flashing cm7.
Hi Guys,
I have a similar problem. I am a total noob-I've had my I896 cappy (Canadian Rogers based) for about a year now; i fiddled with it on Saturday and also got the bootloop. I freaked out, and managed to further flash (out of frustration and confusion) the cappy with another wrong ROM, the I900. I managed to get it back into DL mode and tried flashing stock eclair or 2.2 froyo via ODIN. For some reason, whenever I start the flash (press start on Odin with the froyo 2.2 file on PDA), the progress fails at the factory section. I don't know much about jigs yet, but any tips would be greatly appreciated.
thanks
Chord in the back of the PC directly attached to the motherboard NO EXTERNAL HUBS, right click on Odin run as admin.
Once you have it working READ AND UNDERSTAND WHAT YOU'RE DOING, BEFORE DOING ANYTHING ELSE TO YOUR PHONE
This is probably the easiest guide on how to make one. Layman Jig First one I did I butchered a pare car charger to make it. You can just grab one from MobileTechVideos.com for about $8.

Hi guys,
Thanks for the link.
From what I understand, a jig is an improvised connection that allows your phone to go into DL mode. What if my phone is still capable of going into DL mode? My apologies, as I am at work.
Im not sure what you mean with your question. What the jig does is give the signal for it to go to download mode as was intended by samsung. Same theory on how your phone knows its connected to your computer, or the wall or the car charger. Its by manipulating the current between 2 pins. Keep in mind your phone should always be capable of going in to download mode assuming the hardware is working and your bootloaders are in working order.
I believe I read it on a different website that as long as your phone can go into download mode, then it is only "soft-bricked," meaning it can still be recovered using ODIN. I don't know If I was misinformed or not. I guess my question is, since my phone is still able to go into download mode, but the flash is still failing, did I DL the wrong ROM, or was the copy of Froyo 2.2 I DL'd corrupt? If so, is there a reliable source/site where I can download Froyo or Eclair?
I hope that makes more sense.
Read my post after yours...

^What he said. If that fails could be a faulty cable.

You are correct, if you can get into download mode you are not bricked. Make sure you are using the usb cord that came with your phone, plugged directly into the back of your computer. Make sure your SIM card is out, you're logged in as an administrator, and that you start odin before you plug your phone in.
If it still doesn't work, try another computer and/or another cord.
Why do people say take sim out? Ive never taken it out and had no issues. Just curious.
That is a practice from way back in the winmo days, sometimes the flash would corrupt the Sim itself. Not the case anymore for the most part. I'm with you never take mine out either.
Thanks guys, I will try this at home; hopefully it works.

I say it because, while I've never had it screw up the SIM itself, I had a situation where I forgot to remove it and then couldn't get odin to complete a flash on several attempts, resulting in a soft brick that I couldn't flash out of. As soon as I removed the sim, Odin flashed without an issue.
Coincidence? Maybe, although I didn't change anything else. If it possibly keeps me from repeating this terrifying event, though, I'll just keep doing it

Did you get a red "FAIL" message on ODIN? Because thats what I got several times. My buddy also tried and he got the same thing. The green progress bar completes up till about 80 percent and gives up on me. I'll try taking out the SD and SIM cards when I get home, hopefully it works.
Hi guys, little update:
I found this on the forums and used it:
http://forum.xda-developers.com/showthread.php?t=731989
Anyways, this worked after my second try. Interestingly enough, it worked once i removed the Sim card, which is what apbthe3 suggested..great! I'm just glad my phone is no longer bricked. Minor issue though, my phone is now an AT&T phone, but unfortunately, I am a Canadian Samsung user. New problem now. My phone is no longer rooted (never was actually, but was bricked in the process), I'm happy it works, but i need to know if there are any Canadians out there that know how to revert my device back to Rogers.
Any help would be great. Anyways, the link I provided works great, so its a great resource for our American friends.
Why don't you look at Cognition 4.x.x? Froyo stock ish looking rom tweaked out the ass very fast. Good rom.
Look in development. There are a couple of threads there just for Rogers users.

[Q] Major phone issue (hardbrick?)

I tried flashing the ics source port but forgot to flash cm7 first... It flashed fine and I followed the procedure to flash. The phone would turn on but always go straight to recovery. I figured this was because I didn't go to cm7 first, so I went to flash it but I kept getting errors. I went to flash stock, it started going so I walked away. When I came back my phone was just a white screen and odin was stuck at sbl.bin. So now I can't boot up the phone, there's no bootloaders, just a black screen whenever I try to do anything. The thing is, I can get into download mode just fine through button combos which leads me to think it's not bricked. However, odin/heimdall will not recognize it... Anyone know what to do?
EDIT: View last post by me.

Try the things listed in the "connectivity issues" post attached to my signature. If none of those works to get Odin/Heimdall to see your phone, post back.
followed it. Didn't recognize for like a minute then it showed up. I started it but it's stuck at do not turn off the target
tried again and same thing
What is it showing on the computer side (i.e. what is Odin/Heimdall saying right now)?
I'm using odin right now. But heimdal would always just say not recognized or whatever it says. Odin, when I get it to finally recognize after waiting a minute using your method, it just gets to DO NOT TURN OFF TARGET! and stalls there.
I got it to work. No clue what made it finally work

Good to hear. I know the feeling - it's like the computer/phone are just messing with you.
Damn. A similar thing happened. I had to flash to stock since button combos weren't working, and all the sudden while odin was running my screen just went black. I waited to see if anything would happen, but everything just stalled there. I've been trying to use my homemade 100k ohm resistor jig, and button combos to get into download mode but nothing seems to be doing anything. Am I bricked?
If u have no signs of life at all (no battery charging screen when u plug into a wall charger or no kind of something happening if u try to power it on) then u r hard bricked.
But there is Jtag and the Unbrickable Mod.

Its cheap and keeps your phone from ever being unrecoverable again, it is better than paying the $150 for a replacement.
Sent from my I897 using xda premium
Yeah and seeing as how I'm planning on doing a bunch of development on it once I get another phone, I'm probably going to need it.
I have it and it does come in handy

Sometimes, if you get a lucky brick, the UnBrickable resurrector will work without any mod. This is rare, but its a shot. If you need a mod and don't have the tools, pm me.

I had something similar happen to me,when I was running A6 or A7. I even noticed that I was losing folders that were visible on CWM. I was going to try to re-flash the ROM, but those folders were gone. What fixed it for me, was I did a Factory Reset, and al of the lost folders came back, and I was able to Odin back to stock. I was one of the more weird things I'd seen with my Cap
