[Q] Stuck in boot screen - Captivate Q&A, Help & Troubleshooting

I was running CM7 nightly builds. I was attempting to switch to the stable CM7 build with an ODIN restore. I couldn't get ODIN to recognize my phone, and a forum thread said to try re-installing the update.zip file from the recovery boot. It got hung up trying to do that and upon reboot, it is now stuck on the startup screen. Can't get to recovery, can't do anything. Any thoughts?
Help is GREATLY appreciated.
Thanks!

have you pulled battery and started again? tried button combos? have you used odin since installing cm7? i believe it needs different drivers..... more info will get you more help. more reading will keep you out of trouble (mostly) i've never used cm7 so i can't help that much...

I have tried pulling the battery, running the battery to dead and then putting it on the charger, all the button combos.
I have not tried ODIN but thats because ODIN needs to be in download mode and I cant get into download mode. The only thing I can get to is the AT&T World Phone screen with the white background. I have done some google searching about getting stuck on the boot screen but none of the threads I have found have seemed to mot relate to my exact problem. I am currently looking into if this is the kind of problem that a jig would fix.

definitely sounds like a job for a jig.. it will force it into d/l mode as long as the bootloaders are not corrupted..... best of luck

if the bootloaders are corrupted, is there anything to do or is the phone just finished?

Jtag/unbrickable mod

I had the same loop yesterday doing something else, but i had the ATT boot loop and no button combos worked to get into DL mode. So I tried pulling the battery, then holding vol+/vol-, putting battery back in, and then plugging in usb cable. Went to DL mode. If that doesn't work, I'm sure a jig would.

Jtag should only be used for hard bricked phones. Since there is a sign of life, he can probably recover from this without the need of jtag.
Use a jig. It's the easiest way to get into dl mode. If you don't have one, you can make a crude one that will work until you can get a proper one ordered.

That got it into download mode! I am going to try and ODIN restore and see what happens. Thanks!

ODIN Restore worked! I had to restart it a couple of times but I am back on stock. Now to get the stable CM7 becuase I don't think I can handle stock ROM again...

I know,Another Bricked Phone...sigh

I had loaded the ginger clone rom and all was well. I then however wanted to swap kernels so i loaded up seitrons cwm 1.5.6 and proceeded to flash through cwm. this has now become the worst day of my life. the phone will not boot past the galaxy s screen. i cannot not get into recovery and both computers now say usb device not recognized when in download trying to flash odin. i am worried that something is corrupted on my phone because not matter how many times i uninstall and reinstall the drivers no luck. i think it is officially bricked and im sol. maybe some great minds can figure it out here.
It's not bricked - issue is trying to get your computer to recognize your phone when in download mode so you can flash it back.
What OS are you running? Also - where did you download the drivers from? Some seem to work better than others.
If you can get to the galaxy screen you might still be able to to get into recovery. pull out the battery and use the 3 button combo. Hold down both volume button then power and let go of the power button after it turns on. then just reinstall the rom
I'm willing to bet you can also get into Download Mode either with button combos, or a JIG. Once in Download, you can use Odin to restore to JF6, and have a working phone to flash around with again.
i can get into download mode no problem. and i think it is quite possible drivers are corrupted on the phone itself. my wifes phone works on the same exact setup. no usb device not recognized error. i have tried the drivers from here and samsung directly with no luck. 3 button combo does not work. sim out sim in battery out and in. but like i said it will just not register with the comp and hers will. so im going to att and seeing about replacing it. but i will see how that goes. ive done this lots of times with no issues ever.
download works
3 button combo does not so no recovery
usb device not recognized error
thanks for the help and keep it coming i will try everything if i haven't already.
Try current usb port

Think I'm in worse shape. Tried flashing just the kernel to get BLN working again (last ROM I put on somehow loaded a non-compatible kernel). Now the phone boots the white ATT screen and just sits there. Can't get it into D/L mode with 3-button and doesn't respond to computer I have been using to flash ROMs for a couple weeks now...
Am I hosed? ANY help would be greatly appreciated...
You could try to use a JIG to force your phone into Download Mode
Okay...well, got into D/L mode finally. Used Odin to get it back to factory. Used the One Click rooter again, except now it boots to recovery 3e, which doesn't let my power button work as the okay button Pulling the battery to reset it, but it will no longer go into D/L mode to use Odin again. It keeps booting to the recovery Utils, which I cant get out of...*sigh*
Thoughts?
at least your able to do something i still cannot get my phone into recovery or to be recognized by the computer. it is not the drivers so i have no idea. i can only think that something got funked up with the kernel flash.
if you are getting into 3e recovery then you are most certainly NOT using the JF6 one click stock
3e recovery comes on JI6 which is the FroYo leak....completely different builds and roms
have you tried a different usb cable? I was having this problem, and the stock samsung cable was B.O. and wasnt working... i tried my blackberry one and all was good

I just want to quote this to stress the importance.
Thank you, didn't realize that (still sorta new to this)...
I downloaded a zip (I thought from here somewhere) that extracted into the 4 files. Anyone got a link to the JH6 set of files?
I also downloaded DG's "One Click Odin", but it doesn't seem to really do anything when I run it unless I manually load all the files. Also, I don't see a "Master Clean" like the post refer too
are you sure you downloaded the right odin? in the one click version, theres no option to load files at all. only a "start" and "master clear"
make sure the odin one click is open before you connect your phone.

You guys rock! I don't know how, cause I could have sworn I D/L'd it from that link before and I got the generic Odin, but it looks like I have the right one now! Thank you for your patience with us noobs as we start getting into this new world!
glad you got yours working. i have officially given up and receiving a new one on tuesday. i tried everything but somehow someway the phone is not recognized in download mode. oh well have to mess the with new one then lol

[Q] Will USB JIG Work Failproof in My Case?

Hi all,
So my cappy is stuck in a boot loop after something went wrong with CM7. However, mine is a phone with a locked 3 button combo and even after CM7 RC1 I was unable to get unable to get into download mode with the button combo, which is weird because it should work on CM7.
And plz don't tell me to try again because I have done it atleast 50 times. So I was considering trying a USB JIG. When stuck in boot loop I see the CM7 logo and then it goes to recovery and gives an error saying that it is unable to mount the sd card. Then it goes back into its cycle.
I just want to know if this USB JIG is failproof and will guarantee on putting my phone in Download mode. If not then I wouldn't want to waste 5.99 on it.

I wouldn't mind purposefully screwing up my phone with water and sending it in to Samsung after applying bleach to the white indicator . That's a last resort of course.
Thanks!
as long as theres signs of life a jig will work. if u dont wanna spend $6 u could always build one for a couple dollars at radioshack for some resistors and microUSB if u dont have a spare connector. you can find some tuts on how to build a ghetto rigged one

What were you doing that got you caught in a boot loop? Can you get into recovery?
If you can get into recovery, you can reflash, or run a kernel cleaning script. I know those have gotten me out of boot loops before. I can't say that I like the sound of that error, though.
I'm not going to tell you not to get a JIG. They're amazing. I'm just saying.... in the meantime, you could keep trying
and its not wierd that after flashing cm7 your 3button como still doesnt work. CM7 does not touch the bootloaders (which control the boot combos).
If you plug your phone into the computer you can use "adb reboot recovery" to get to recovery and fix your bootloop.
On a bootloop download mode wont help much except to flash back to stock.
Your kernel Sounds messed up, use a jig then DL mode back 2stock. OR If you actually have cm7 already successfully installed. All you have to do is pull the boot.img out of the zip. And put it in kernel spot on Odin. Then flash it. That will fix the kernel.

I've haven't had to use a jig to date yet. I've been lucky enough to keep holding vol up/down and plugging in the usb into the computer and its put it into download mode. If it doesn't work the first time, keep trying. Its always gotten me out of a pinch.

[Q] Download Mode Gone?? WTF

So I recently made a thread how adb wasn't working and that evolved into not being able to get into download mode. Now after not being able to get into download mode for days, I'm still stuck on cm7 with no way of getting back to stock. 3-button recovery won't work, the only way to get into recovery is adb reboot recovery. No button and cable methods work to get phone into download mode as well as adb reboot download. I even recently tried http://www.youtube.com/watch?v=lojU5bvGz3c which is a makeshift usb jig. I successfully made it but it would only turn the phone on. WTF. I'm afraid to buy a real usb jig from online because it most likely will cause the same thing. What is there to do? I'm completely lost. The phone works, the rom is okay I just cannot get back to stock and get rid of cm7. There are lots of issues I need to fix and cannot because of this. Any ideas?????
EDIT: Now I'm completely f'ed. I tried flashing cm7 instead of MIUI again to try once more if I would have better luck on just cm7, but during flash in cwm the phone turned off because the battery compartment was loose and now the phone boots up and goes into recovery shows some code then turns off again
(This post just in case anyone missed the reason in the edit)
Reason: EDIT: FIXED! Don't know what happened. Rearranged resistors and tried again and finally got it

What's your process to get CM7/Miui installed?
On a side note, ADB won't connect to your device unless you have the Nexus S drivers installed on you computer when CM7/Miui is installed
When I was last on cm7 adb reboot download doesn't work.
Drivers installed
Just sayin
Sent from my unbrickable cappy *bam*
yeah, i distinctly remember the first CM7 build threads that came up here saying that adb reboot download DOES NOT work, and you DO need working 3 buttons or a jig
not sure why that was removed from the threads
A jig should work
You might be coming into contact with the resistors (I can't watch that youtube video from work--firewalled--so I don't know what the setup looks like). Any contact with the them will make it not work. Try insulating them more with some heavy packing tape.
I cut up my mini-usb plug from my car charger (didn't need it), and peeled off all the plastic so I could easily touch the correct two pins with the jig when the hacked up mini-usb is plugged in. Works like a charm. Sometimes if you aren't touching them just right, or if one end of the pin is touching the wrong point the power will come on.
Try harder with the jig, I guarantee you it will work (and you shouldn't have to buy one--it's too easy to do yourself for less than $2 and about 5 minutes).
Good luck!
Just a thought. Are you installing GB boot loaders before flashing CM7/Miui? If so, the way to get into Recovery/Download mode changes. Recovery is vol+/power, Download is Vol-/power.
Just thought I'd toss that out there...just in case

No download Mode after I897 GB Bootloaders on CM7
Hi there, i've got a question. If i can't get into download mode using the 3 button combination nor the Vol- + Power nor the connect+press buttons+insert baterry trick , do i have chance to get into download mode using the YIG? Thank you
I've lost the 3combo after installing the GB bootloaders with CM7 but the Odin Connection was lost on the SBL, The phone is not even Powering on anymore
If your phone has no signs of life at all, then sadly you are hard bricked...
But it can be fixed through jtag or the unbrickable mod.
So is there hope?

Yes, according to those that have done jtag or the unbrickable mod, these methods are successful. To get better info though, I would recommend going to those specific threads.

I don't think you need jtag (but you can look into it). If your phone is able to at least power on, you should be able to use a Jig to get it into download mode. That is what I did with mine when all the options fail.
good luck.

If the phone doesn't show any signs of life (wich it wont if he failed on sbl) Jtag or Unbrickable Mod would be your 2 best bet. (Id use Unbrickable mode since it will protect you from future issues.)
Sorry haven't checked this thread in a while. My process for going to cm7/miui is flashing stock eclair through odin one click, then rooting and installing cwm. From there I just flash the latest nightly or whatever it is. Nothing I'm doing seems to be wrong
The problem is that I should be able to get into download mode without having to use a jig every single time. 3 button combo should work, but it doesn't when using cm7/miui for some reason

Interesting Problem with Cappy

I've Had my cappy for something over a year and up until i finally got a working jig it was out of commision for about a month, Then all was saved with the jig and i reflashed stock and started from scratch trying new roms, Then, when trying to go from stock to apex using their own odin flashers, Then when it went back into recovery i hit reboot to begin using CWM. Then all of a sudden, The Gingerbread version of the softbrick screen comes up, Phone----!-----Computer. No worries i have my jig, then when i remove the battery, wait and put the jig back in . . . the phone just shows me a bricked screen again, with a jig i know worked. What have i done?

If by "bricked screen" you mean the Phone--!--Computer screen, you should be able flash back from that screen. In theory, ODIN should recognize your phone at that screen in a manner similar to the way it recognizes it at the normal download mode screen.
As long as you see the computer/phone symbol you should be able to get it reflashed with the J6 Oneclick. If it never appears in ODIN try all of your USB ports. Odin only sees my phone on the two rear ports, go figure.
As far as getting the yellow download screen goes you might consider some other key combos before you declare it non-functioning. Did you flash it back to stock J6? If so, did the 3-button stop working? That may be your issue. Also, you may have put boot loaders on it from another device such as an I9000 and changed the key combo while flashing another ROM. Try battery pull/replace with vol up and USB, vol down and usb, both up/down with USB and see if any of those work.

Installed cyanogenmod 9 and bricked.

So, the phone worked well with CM9 for a while. Then the guy that owned the device attempted to update it, I'm not sure what went wrong but the fact of the matter is that it kept bootlooping on the CM9 splash screen. Entering into recovery was unresponsive and doing the three button combo to enter into Download Mode was unresponsive.
I followed a guide on here on how to make on my own jig. I successfully made the jig and I am able to enter into Download mode now. However, I am unsure what to do from here. I attempted to use Odin and flash a Corn kernel for the captivate, thinking I'd be able to boot into recovery and then flash a rom from that point. Unfortunately, I am unable to do this. Nothing boots up except the ATT screen now. Maybe there is a failsafe way in getting the phone back to working order?
Any advice would be appreciated.
Have you tried pulling the battery, holding down both volume buttons, and plugging the USB cable in to enter download mode? Once there, try flashing it back to the original state with Odin One-Click or similar. I have bricked and unbricked my phone at least twice, and each time was able to get it to recover by using this method. Hope it works for you. Good luck!
Thanks, it worked. I think I'm on Froyo now, but at least its working. I originally downloaded Odin-one Click but didn't recognize the interface. Thanks!
