Please help me unbrick my Tab... *video added* SOLVED - Galaxy Tab Q&A, Help & Troubleshooting

Ok, I have an AT&T Tab, completely stock except for root. I downloaded the .apk to make sure my bootloader was fine, and it passed.
Wanted to install the Overcom ROM, so I followed the tutorial.
I got as far as the Odin step. The overcome kernel flashes just fine, but when the tab reboots it never gets to the samsung boot screen. It just sits black with the backlight on after the AT&T screen. After leaving it like that for awhile, I turned it off and tried to get into recovery. Same thing, it just sits black with the backlight on, won't boot into recovery.
I downloaded and installed Roto's latest JMI and got it working again, but its still very odd. Ive used Odin with my Captivate quite a bit, and it seems to be working just fine.
Whenever you boot it sounds like its working perfectly fine, but the screen is blank with just the backlight lit. It stays blank until you hit the power button, then it turns off, then you hit power again, and it turns on perfectly fine and works.
I tried getting into recovery and its still doing the same thing, blank screen with backlight on. I have no idea if its in recovery and I just can't see it or if its locked.
Also forgot to mention, whenever the screen is blank with the backlight on, there is white line that goes down the screen on the right from top to bottom. And now, even when its booted up and running the JMI firmware, that line is there the whole time.
OK, let it charge for a few hours, and the line was gone. It seemed to be running ok, so I downloaded a terminal emulator, and tried to reboot into recovery. It rebooted and did the same thing, AT&T logo then blank screen w/white line. Now its stuck again, it won't even boot up. Also, it still gets into download mode just fine. It comes right up, and no line.
Any ideas?

I thought JMI was stock firmware? What else is there? Someone posted the stock AT&T firmware, but as dicussed in the thread, it doesn't work. I tried it. This isn't a simple getting stuck at the boot screen, it doesn't even make it to the boot screen.

Added a video to the OP...

Just tried flashing the T-Mobile stock firmware for giggles. Same results as the Roto JMI ROM. You can hear it booting up, but all you can see is the backlight with white line. You can turn the screen off then on, and use it. It seems to work ok, until you turn it off, then it won't boot back up, just gets stuck like the video.
I've already contacted Samsung for a warranty repair, if I can't get this figured out (or someone here) its going back tomorrow.

If you look a little in the general section you will find a thread called at&t black screen with thin white line fix. It's a simple fix that involves flashing the jj4 bootloader. This happens to almost every at&t tab.

Good god why isn't that a sticky anywhere? I almost sent this thing back! Its working perfectly fine now. I'm currently converting to ext4, then I'll flash the Overcome ROM.
Thanks again man you saved me from sending this thing back. (I was even looking at Xoom reviews today )

Use 3button fix odin, not one click, and check "re-partition". I'm pretty sure thats what i read in the CM7 thread about this

VZW Tab with Khasmeks KleanMod Problem

Big PROBLEM. Everything was great with the Rom and overclocked kernel. Then the force close acore happened so much, i thought i would perform a restore. But did it through Rom Manager instead of CW recovery. Well Rom Manager threw me into the original android recovery? and it will not allow me to do anything. I get the white triangle with exclamation, when i touch the home button it gos to the Android sytem recovery screen instantly, but does not allow any functions. Push and hold power off is all that works. Then reboots to the same exclamation. I tried flashing both the Khasmek kernel and rom via Heimdall, which reports succuess, but im am still at the same exclamation. Am i bricked?

Can you get into download mode??? if so you not bricked.. voodoo mod was very glitchy for me, when i flashed overcome rom to my verzion tab.. i couldnt wipe anything i got that same screen with the triangle and not matter what i was doing it would go back voodoo cmw options then triangle. so finally i reflashed back to stock then booted into original recovery and wiped from there, both data and cahce. i was able to boot back up into android, from there i reflashed voodoo recovery and oc kernel and then was finallly able to use my nandroid back up.
stay away from rom manager, just power down the device to get into recovery or download mode. with the device off hold down power button and volume down button and yellow triangle should appear then flash back to stock... your gonna have to reboot into recovery after stock flash, and wipe both data and cache this should get you back up and running.
Its just getting ugly. Wont even power down. when i push and hold power off, just turns back on into the triangle exclamation, again, touch the home button and im in stock recovery screen with the exclamation still on that screen too. I can scroll up and down with volume, but when i push power to select nothing happens. Yes, i can get into download, like i said, ive reflashed everything successfully, according to heimdall, but nothings changed, just boots back into triangle page.
well,
i got lucky this time. found the original vzw files and installed them via heimdall. Seems to have taken me past the problem. Wow, that was scary

yea man i got freaked out too.. i had the same problem with powering down, i just kept holding the power button down finally it shutdown.did u get the msg saying back button is disabled. then a few seconds later back button is enabled, while in voodoo recovery?? how did u make out with the nandroid backup?? i got my to work after reflashing back to stock and then reflashing v3 kernel and vooodoo recovery..
Khasmek has a thread for the rom.. why not just post in there? This if not there would belong in q&a

Google found them WHERE? I've been searching for hours. I need original VZW VCast files back so ECO2 script won't crash when it tries to update them.
Update... I never did find the VZW files with Google Search, but the fix here in this thread restores everything back to stock including all the VZW bloatware. The fix works like a charm, by the way, for completely restoring the Tab back to stock.

[Q] Rogers i896 AIO captivate failed?

Hi, i used baywolf's AIO captivate rogers 2.6 to flash back to stock using the supplied odin. It went alright and odin said that it completed successfully. I closed odin and reinserted the battery, there i watched it boot up and the rogers splash screen was up for a very long time. It eventually just shuts off after staying at the rogers screen. Help anyone?
reboot into recovery
wipe user data and wipe cache.
check out the rogers stock rom links in my sig.
full instructions and the same files AIO uses. (he uses my files)
Hey, i was about to go out and buy some resistors to make a jig because i didn't have the 3 button recovery fix. Then i tried wiping user data and it rebooted, to my surprise it loaded into the lock screen. All's perfect now, thanks for your help.
jig only helps if your screen doesnt come on.

Thats not true at all. It helps if you are in a situation where you can't boot properly and your button combo doesn't work. His combo obviously worked because he made it to recovery...
ok... true.. was talking about him... didnt consider other readers...
But isn't the screen not coming on at all a sign of a brick and not just a "soft brick"?
I know you had those couple of weird ones but that isn't the norm, and I haven't heard anyone else report success with a jig like that...
yeah but with my trick i found, the natural tendency when putting in a battery is, see if it turns on, ie push a button, which breaks the trick, i wonder how many people could acutally get unbricked with that? or just holding the buttons long enough... lol..
Hahaha...canadians...y u so funny?

[Q] Bricked phone? flashed SlimICS through Clockwork

hey all, i've had my captivate for about two years now, and for a while i used cognition, then for the last year i've been using firefly. firefly has completely destroyed my phone's speed and responsiveness, and i needed to clean everything off and start with a minimalist ROM. so i picked slimICS.
i'm still very hazy on the details and terminology of flashing ROMs, but i got two to work (i remember using one-click root thing in 2010, and then in 2011 i flashed firefly through clockwork) so i figured it shouldn't be a problem to install slim, which i figured would be my last ROM until next year, when i'd get a new phone.
so i backed up my stuff, tried to get into recovery mode with the 3 buttons (didn't work, unsurprising since it didn't work last year either), took out my SIM, went to CWM, and selected the flash rom option. this restarted the phone and sent it into recovery mode--except it was the stock recovery, and i couldn't select anything because i think firefly made the phone think it was the i9000 model from canada, instead of the i897 captivate, so it assumed i had a physical "ok" button on my phone (which i obviously do not). i tried the power button, the various capacitive buttons on the bottom, nothing would select any of the options, so i just took out the battery and put it back in. the phone immediately booted into the CWM recovery menu, in which i selected flash ROM, and scrolled down to choose slimICS.
i let it do its thing for a while, it jumped between the AT&T white logo screen and a screen with scrolling text for like 5-10 minutes, then just stayed on the AT&T logo screen for another ten minutes. i should have left it for maybe a half hour to be sure, but i figured the install failed. i couldn't get out of this so i pulled the batttery. and now the phone is bricked (soft i hope). if i hold the power button it goes to the AT&T white logo, flashes briefly for a half-second and goes back to the screen, then stays there indefinitely. no button combinations seem to work. does anyone have any suggestions?
thanks!
Since you backed everything up, I'd suggest flashing a stock rom via Odin or Heimdall to clean everything up before moving forwards.
You can flash a non-bootloader one to be safe, or if you want to make sure you can flash anything, flash a package with Gingerbread bootloaders.

how do i flash anything in my phone's current condition? it doesn't turn on fully. it's stuck at the white AT&T logo.
Turn it completely off (pull the battery, if necessary), then hold V+ and V-, and insert a USB cable. That should put it in download mode. Once you're there, you can flash a stock rom (There's a stick with those roms in the development section).

doesn't work. as i mentioned in the OP, i can't get into download or recovery mode or whatever. these button combos have never ever worked with this phone. for example, holding + and - and inserting a cable with ODIN open has never done anything. that's why i used clockwork.
Sounds like u r gonna need a Jig. If u are on a pc, click on my sig link below and there u will find a link on how to make a jig and/or where to buy one.

is that guaranteed to work? or is it most likely? or is it unlikely at this point?
The jigs that I have made myself in the past and as well the professional made ones that I have purchased have always worked to get me into download mode.
The jig is worth a try, I suggest you should
if I'm reading the op right, and if memory serves firefly was an I9000 build and button combos are different. My suggestion would get the Odin kk4 one click with repartition and WITH boot loaders from 4-2ndtwin's sig links, open that and while powered off and holding just the vol- button insert the USB that should do the trick. I9000 builds use different boot loaders with different button combos. Since you will be flashing a boot loader package be aware this is when you can truly hard brick your device. Be sure you have a good connection and cable before starting. If you still can't get into download mode I can +1 on the jig. The jig and 4-2ndtwins one click has saved my bacon more than once.
ok so i bought the jig, and good news: it gets me into download mode! yay!
problem: i don't know where to go from here. i've tried the following:
A. after getting into download mode, i followed the ODIN method here: http://forum.xda-developers.com/showthread.php?t=1350266, meaning i flashed the gingerbread bootloader update (nothing happened to the phone, which made me confused when i got to step 7., because i was STILL IN download mode), then flashed the speedmod kernel (which reset the phone, but it just got stuck in the "SAMSUNG CAPTIVATE i-897" white text on black screen, forever. i had to do a battery pull. turning on the phone goes to the same screen and then it freezes. trying to hold all three buttons to go into recovery mode alternates between that screen and the white AT&T screen, actually alternates, forever if i let it.
B. after that failed, i tried using the 2.2 Heimdall one-click (http://forum.xda-developers.com/showthread.php?t=1266172) but the file, when run, says
Code:
ERROR: Drivers Not Found
Installing drivers
but i still followed the instructions (except the instructions say "Install driver" but the actual button is "Replace driver"?) in any case, this does nothing. and then checking off "Flash bootloaders" and doing it again does nothing. the phone remains in download mode.
C. so i wanted to try one-click downloader http://forum.xda-developers.com/showthread.php?t=731989, but nothing pops up on the ODIN window when i plug my phone in. i can't even do anything.
please help!
please, does nobody know what to do?
Take a look at the "Captivate Connection Issues" thread for some more things to try. At this point, it sounds like you need to clear all the phone drivers off of your machine and reinstall them.

thanks, that worked! (it was my laptop that was the source of the connection issues i think; i tried all that stuff in the thread, but when i switched to the desktop, all of a sudden ODIN recognizes the phone!) i got my phone to flash ODIN one-click. so now i'm back to stock 2.1 eclair.
however, much to my dismay, i still can't get into recovery mode to (re-) root. the three button combo still does the weird flashing thing, where the white AT&T logo shows up, then the screen goes to black, then the AT&T logo, then black... ad infinitum. how do i either 1) enter recovery, or 2) re-root the phone + get a nice, lean, fast, modern ROM on it without going into recovery?
so far this thread has helped me unbrick the phone, now all i need is to update it from stock!

I could be wrong but when you do the 3 button combo it sounds like you are continually holding the buttons which will cause it to keep looping like you describe. Starting with your phone off hold down all three buttons. The phone will show the white ATT screen. Then if you had a custom kernel it would show the kernel splash screen, in your case you said it just goes black which is fine too. Then you will of course get the white ATT screen again. As soon as you see the white ATT screen again release all the buttons and that should boot it into recovery.

i tried various durations of holding the buttons. none worked. 2nd AT&T logo, nope. 1st black screen, nope. 1st AT&T logo, nope.
Your gonna have to get ADB set up on your pc. Then... "adb reboot recovery" will get u into recovery mode.

GT19000

Help please. After trying to reflush my old firmware with Odin, it got as far as OSM -All threads Completed, (successful /0 ,Failed /0)
It got stuck in there so I had to remove the battery and try again but it just keeps doing the same thing. After disconnecting from the computer
all I have now is three small icons on the screen: one tiny phone, a triangle with exclamation mark and a computer. I downloaded Odin and the correct firmware from this site, so what has gone wrong and how do I proceed?
Many thanks
You need to enter download mode again and reflash

Hi,
Thanks for that.
After several trials, I did manage to get back in download mode and managed to flash the installed Firmware 2.3.6 without any problem.
After resetting, everything seemed to be working fine. However, I left it turned off overnight, switched it back on again this morning but
nothing has changed. My original problem was that on switch on, it takes ages for the phone to activate. I get the welcoming screen
that goes away, comes back for anything up to 5 minutes until it eventually goes on to full screen and everything works well.
So what is causing this problem and what else can I do
