[Bricked?] Infinite Boot Loop - Captivate Q&A, Help & Troubleshooting

Yesterday I attempted to flash back to stock with ODIN, but after the program said the operation was successfully completed I was left with a problem.
Now, whenever I attempt to turn on the device it hangs at the AT&T logo for about 10 seconds, the screen goes black, and this repeats indefinitely. And whenever I plug the device into any outlet there is the loading screen before it shows how much battery you have, but before it shows the green bar in the battery the screen goes black, and also repeats indefinitely.
I've tried all of the button combinations but cannot seem to get into download mode or even recovery mode.
There was one time where the device booted up, after about an hour of the AT&T logo flashing, but right after the phone booted up it shut down because it died.
Is there anyway I can get into download mode from this state?

You have a late build phone, you flashed Odin one click to 2.1, later builds phones just bootloop with 2.1, and those bootloaders trend to break the button combos.
You'll need a jig to force download mode.
there is a sticky at the top of the dev section with stock packages, I'd suggest grabbing a gingerbread packages with bootloaders, so your phone will boot up AND it'll fix your button combos.

If anyone wants to know, I was able to fix it quite easily, it just took a lot of patience and without a jig.
I first charged the phone for about 4 hours.
Then I turned the device on and let the AT&T logo flash until eventually the device turned on.
Since I was on 2.1 I was able to use the oneclick root application to root my phone. Amazingly it actually went into recovery and I was able to apply the update.zip.
Next I rebooted the phone and waited until it finally turned on again, from here I downloaded a command line application and was able to use that to force the device into download mode.
Finally, I used Heimdall oneclick and my phone was back to normal.

[Q] all apps are crashing

I installed Amimod that lets me change the transitions between apps, i ran it to change it to a cross fading transition and it said i had to reboot later to make the changes take effect. I kept that and mind and used some other apps. They all didn't load and gave me the "com.xxx.xxxx is unable to continue" type deal with the force quit button.
So i restarted my phone and now launcher loads but the pop ups come saying "com.android.phone is unable etc" or "com.android.media is unable...". There is no status bar and the phone doesn't lock. After about five minutes of trying to press the force quit button, nothing happens. I went into recover mode and cleared my cache but that didn't help.
[tldr] I can get my phone into download mode but is it possible to open the phone as a root folder on my computer so i could uninstall Animod and any changes it made? I don't want to master reset.
ROM reflash is only option.
I reflashed using odin but now its stuck in a boot loop with the att logo. When i plug it into the usb it loops the loading sign and the battery sign. What now?
Have you used odin before?
Which odin did you use?
What build is your phone?
Can you still get into download mode?
I have not used odin before this was my first time.
I used the one that is prepackaged with the .pit and .tar file "I897UCJF6-final-OCD-REV0.exe"
My phone was stock android that i rooted.
Cant get it into download with any button combo.
Under your battery left side on the white sticker. Your phone had a build number. Mine is 1008. 10 meaning 2010 08 meaning august. What is yours
Also tell me exactly what you have tried to get into dl mode
Build number 1011, and now my phone wont even turn on. When i hold the power button it is unresponsive, and its not dead i charged it.

Looks like you will need to try to force the DL mode with the odin instructions or get a jig and see if that works
Download mode
remove all sd, sim, bat
Put bat back in
Hold volume up abd down
Plug in usb
In it works great, if not usb jig
Going forward do not use odin one click use this method
http://forum.xda-developers.com/showpost.php?p=10056254&po
i got it into download mode using the button combos (battery out then hold vol up and down etc) and used the odin 1 click downloader for captivate, but it failed twice.
It got to the point where I had to buy some resistors to make a USB jig. The jig worked fine and put it into download mode but Odin still failed...Twice more. Now my phone wont even show the logo when i hold the powerbutton and the jig doesnt seem to work anymore. Its not the battery because i charged it for a full night before i tried jigging it again.
I would try the non one click odin method now except that i cannot get my phone into download mode.
I have no idea what to do now, it seems like its completely bricked.
At this point (if I'm able to replace it) would the workers at samsung or att be able to access my data at all? I only had the phone for 3 months. And would my warranty be void for rooting/flashing?

Hypothetically, yes and yes, but the reality is they will likely just wipe it and reflash it without ever looking at what's on it. Just tell them something went wrong when you tried to upgrade to Froyo via Kies. That's happened to enough people that they probably won't question it.

[Q] Odin3 not working

I had been using my Captivate for a while, and used Kies mini to upgrade to Froyo, and everything had been working fine until randomly the phone wouldn't boot.
It would take forever to go from the AT&T home screen, and would lag through the galaxy s intro, and then stop.
I tried to use Recovery mode, and it didn't work, so I tried to use Odin3 to flash back to stock.
Now it won't go past the Logo screen, and recovery mode doesn't work, but download mode still does. I have tried Odin one click, and Odin three click v 1.0, 1.3, and 1.7. I've used the .tar and the .pit from Breakin' Ranh's [Guide] How to Recover a Captivate to Stock 2.1 Eclair JH7
It keeps getting stuck in a boot loop after odin, no matter what I do.
Any suggestions?
Using SGH-i897
1007
first boot takes along time to build new files and delvik.. are you sure you waited long enough?
keep trying to get into recovery. try holding the buttons a little after the screen comes on.
factory wipe/ clear phone/
It keeps going to the AT&T logo screen for like 10 seconds, and then goes to the spinning wheel/battery charging screen, and then reboots.
Can't get into recovery mode through it, still.
a different .tar package.... dunno about that one..
or flash to 2.2 tar package
I have to use rom manager to get to recovery on my captivate
Sent from my SAMSUNG-SGH-I897 using XDA Premium App
I was able to use a dragon rom to get it to boot, but now my phone wont give me any access to my internal sd card, and won't mount my external, so I can't download rom manager because I "have no room" Where do I go from here?
I've already tried formatting both cards, and it seems like nothing happens whenever I click on format.
you dont need rom manager....ever
Then what does he need?

stuck in the same position
I can get into download mode (only with a JIG tho) but when I go back to stock with Odin (or try to) it's just stuck in the AT & T logo screen, it doesn't go beyond that, how do I get into recovery mode, press both Volume buttons and Power button, when the AT&T screen comes release the Power button right?
Need some help please!
you might need to flash the 3 button fix but keep trying, if you get into recovery clear data and cache. but first boot always takes a long time as it has to build delvak cache and more... try flashing again, with the 3 button fix att rom.
3 button fix? to get into download mode you mean? I CAN get into download mode (with the jig) but not into recovery mode :-s
I have no idea how to flash it without being in the Stock rom, any help?
download is 2 buttons
recovery is 3 button.
some phones loose the 3 button combo to get into recovery.
in that case you need to flash the stock rom with 3 button fix.
it is for Att only so i dont know much more.
After Odin, I was in a boot loop yesterday. I plan on writing it up in a new thread to see if someone can help me understand what happened (cause I have Odined and modded two different cappys without issue) but here is how I was able to recover.
After Odin was complete and said successful, it reboots the phone.
Upon reboot I was in the ATT boot loop. After Odin, I lost both three button recovery and 2 button download (both of these worked before Odin). I don’t have a JIG so no way of getting to download mode.
I read to try the following sequence after reading it other posts.
1. Pull battery, sim, SD card and unplug the USB. Let it sit for a minute.
2. Plug in the USB cable.
3. Holding all three buttons, plug in the battery.
4. The battery charge (grey) should be seen on the phone. After the phone screen goes black twice let go of the power button.
This worked for me once, after several attempts.
Now that the phone booted back up, I did a master clear with Odin.
Upon reboot right back in to the ATT boot loop screen.
Was not having any luck with the steps above after several attempts.
Here is how I eventually recovered.
1. I opened Odin on the PC.
2. Pulled the battery and USB for a minute or two then replaced it and plugged in the USB cable.
3. After few cycles of black battery icon and spinning wheel, the batter icon turned green (like normal when you turn your phone off and plug it in). Sometimes this only took two cycles and sometimes many cycles (or a few minutes).
4. Once the battery icon was green, I hit the power button.
5. As soon as you see the ATT screen, pull the USB cable and the phone booted (if I left the USB plugged in, the phone went back to the black battery screen after the ATT screen).
6. I copied the correct Update.zip and Rom to my SD card.
From here I tried to boot into recovery via ADB.
The phone rebooted but back into the ATT boot loop.
Following the second set of steps above (2-3 times), I was finally able to get into Clockwork recovery.
From here I flashed Phoenix Unleashed.
After the flash rebooted and the phone seems to be running fine now (with the exception that I lost my 3 and 2 button combos, but that will be for a different thread).
From the Power Menu, I can get into download mode or Recovery no prob.
Not sure if this is something that will work for others but wanted to throw it out there just in case.
It never booted for me, so this is what I did
For anoyone that might find this thread, Odin 1 Click didn't work for me, so I flashed back into stock using Odin (not the 1 click version, another one), here are some links that proved to be very helpful (I ended up Flashing to Serependity 6.4):

this thread to finish flashing back to stock.

Bricked Nexus 6 (Not your typical thread)

So first things first:
I am not a noob, I have been flashing phones for years
The phone has an UNLOCKED bootloader
I know what a bootloader/recovery are etc
So last night I upgraded my phone to 6.0.1. I then decided to root it and get a kernel on for color control. So I download one of the new kernels (Elementalx) for 6.0.1 and the systemless root that he recommended in his post. I flash both files and boot the phone, the phone bootloops twice after the password to boot screen and then it works fine. I install a few things adjust a few things (nothing pertaining to root) and then before I jump into the shower I reboot it. I look at it after a few minutes and it is sitting at the google screen with the padlock, no worries it has happened before so I reboot it only to be met with this same screen. Over and over it just halts here. I do the button trick to get into the bootloader, no dice. No button combination can get me past this screen.
I then go over to my PC and try it out and see if I am getting a Q_BULK issue (I had it happen to my Galaxy Nexus before) and the PC doesn't even acknowledge it, so now I am getting a little worried. I cannot power off the device normally, it just reboots back to here. I can manage a trick with the power cable and some quick button presses to enter the "charging" mode and from there it appears to shut down. Upon boot though it comes right back to this halt. :-/
So, does anyone have ANY experience with this before I contact Motorola? I really don't want to because I have frame swapped and don't look kindly on the process of undoing it for a replacement, but if it must be then it must be. Below is a TLR
Phone boots to Google/padlock screen
CANNOT access the bootloader/recovery through normal means
PC does not recognize it (I did prior in both fastboot and recovery so the drivers are all installed)
the phone does NOT appear to be in Q_BULK
the phone will not shut down, it just boots back to here
It "was" running ElementalX and the systemless root (both are the newest) for 6.0.1
-Current status, sitting on this screen waiting to die... but it has an almost full charge
OK, first off... YOU ARE A NEWBIE.
Turn off the phone and boot to bootloader and use that to load your custom recovery and restore your working backup.
Failing that, fastboot flash the stock image from bootloader mode.
What are you hoping to accomplish by draining your battery completely, this can only make matters worse.
@scryan you are a funny man?
you didnt say anything about trying to get into recovery.. i assume you tried getting unto your recovery?
Hold power button, up and down button all at the same time. If you are on stock recovery wipe user data and cache. See if you can boot into the bootloader afterwards. That's unusual you cannot get into stock or custom (if you have it) recovery.
So you're main problem here is that you can't get into your bootloader or recovery right now? Hmm..... that can't be good. My best guess would be to keep trying to get it into your bootloader, just keep on holding volume down and power for a long time, hopefully if you can get into either bootloader or recovery you can fastboot flash a clean stock image, or restore a nandroid backup (assuming you have one) with TWRP. My best guess though.
Briefly, your device powers on, so there's sign of life. It is either your cable, pc' usb port or the usb socket of the phone is at fault. Did you try with another usb cable at another usb port in the pc ?
Let the phone power down completely. And when it dies, connect it to a charger while briefly holding the vol down button to get into the bootloader. It might take a while since the phone doesn't have any juice but this trick might just work.
If already no warranty, so dissasembly the deive, re-attack your battery

Stuck in Kernel Panic Upload Mode

I tried flashing the latest firmware with Oden and it failed, when I disconnected the phone and tried to put it back into download mode it comes up with 2 lines of small text in top left of screen then screen goes blank for a few seconeds then comes up with a list of stuff in blue red and green text with a little android in the middle of the screen with Kernal Panic
Upload Mode to the right of the andriod.
I can not turn the note 9 off, or figure out how to get back into recovery mode or download mode now. and the battery was nearly full when this happened , when the screen goes blank again after a few minutes the led flashes, if I press any of the volume keys or the power button the screen comes back on for a few minutes and while the screen is displaying the message the LED doesnt blink, then two minutes or so the screen times out and LED blinks again.
if I hold the btton down to try and go into recovery mode it reboots after about 10 seconds, shows the normal Samsung boot screen then displays the 2 lines of text at the same time which are in pink, then goes to the error screen I mention above
PLEASE HELP
Is going to take forever for this battery to drain and the unit shut off so I can try to boot into recovery or download mode...
HUGE thanks in advance
Hi! I got this problem too!
I was following guideline in this thread https://forum.xda-developers.com/galaxy-note-9/how-to/guide-change-note-9-csc-easy-guide-t3879473
I was following the procedure, but in very last step while flashing new firmware something happened to ODIN, it failed to flash it. I tried to restart the phone, but it entered KERNEL PANIC UPLOAD MODE. I was trying to get of this, but I was only able to enter recovery mode which didn't work properly either. It was indefinitely looping between installing update screen and other screen with error messages.
If I try to Volume down power for some time, I get POWER RESET OR UNKNOWN UPLOAD MODE.
So, no way out to get into download mode again.
Hi ckhaustralia, did you end up getting some help or an answer about the kernel panic mode issue with uour Note 9 problem you listed above? I have the same exact issue, except the reason why the firmware flash failed in my scenario was due to the charging port which I believe had a faulty sensor because I got a message half way through the flash indicating there "moisture" in the port. Now no matter what I have tried, I cannot boot into download mode to try and fix it. I think the only possible way would be to use something like a ZX3 box but it would be great to hear from someone knowledgeable within XDA?

bricked?

I was trying to go back to stock after having Lineage installed but it crapped out during the install. The tablet is now stuck on the SAMSUNG logo screen and it seems impossible to do anything to get around it. The only button combo options that work are power+vol down which reboots and power+vol down +home which puts it into download mode. I've tried reloading the stock firmware and twrp using Odin but it always results in the same, the tablet reboots then goes to the standard android update screen, says it's doing an update and then reboots and it's back to the SAMSUNG screen. Nothing I do gets me into recovery and while Odin connects I can't get ADB etc to.
Any suggestions other than throw it in a drawer and forget about it?
TIA
Ok I got further. I left the tablet for the battery to die, then fully charged it, plugged into the PC and then started with the recovery key combo and bingo got the No Command screen then the standard recovery options. Deleted the cache and did a factory delete/reset and it's alive again.
