Where I am:
My Samsung Captivate i897 is soft bricked. When I boot it (On key), it freezes at the at&t screen, or Corn-Kernel screen. I have to remove the battery to shut it off. I can boot into Download mode by connecting USB while holding volume up and down. Odin sees the phone, and I can flash TARs.
If I try a normal boot, the phone freezes at the at&t screen if I flashed KK4_stock_kernel.tar last, and at the Corn-Kernel screen if I flashed CornKernel_UCKK4_v705.tar last.
If I try a recovery boot and I flashed the CornKernel_UCKK4_v705.tar, the phone still freezes at the Corn-Kernel screen.
If I try a recovery boot and I flashed the KK4_stock_kernel.tar, the phone displays the recovery menu. If I choose "reboot system now", the phone freezes at the at&t screen.
How I got there:
I rooted my i897 and was running CyanogenMod 9 with no problems for almost a year. Suddenly, the i897 started using excessive power, discharging the battery in a few hours while the i897 was on but doing nothing with a dark display. The battery monitor said the 60-70% of the power was being used by the Android OS. I factory reset the phone, and flashed CyanogenMod 10.1 (cm-10.1.0-RC1-captivatemtd). The i897 continued to use excessive power. I flashed an old Nandroid backup from a year ago, probably made just after I rooted the i897 and installed ClockworkMod. When I tried to reboot, the phone was bricked. It froze at the at&t screen.
What's wrong? Is there something I can flash from Odin to get the phone working again? Is there some other way to get it working?

Flash Odin KK4 with bootloaders from this post: http://forum.xda-developers.com/showpost.php?p=18370912&postcount=3
From there, Get Corn and then back up to CM10.1.
Now your problem is probably due to a old battery, buy a new one and you should be good to go.
Thanks for the help. As you suggested, I flashed the KK4 with bootloaders, and the phone appears to be back to the factory OS. I will be re-rooting and upgrading to CM10.
As for the battery, I did swap it, and the rapid discharge continued. I will try to go step by step upgrading the OS, and turning on features to try to see if the drain is being caused by hardware or software.

Although you get a black screen on boot, it might still be working....
Chubbyflood,
If you are in the same situation as I am then the tab is still working, you are just getting black screen on boot up. It played tricks on me for ages when I was first rooting by tablet; but it turned out it is just the boot up screen that isn't showing.
This is my situation:
-Press and hold Power button to turn on.
-I see the Galaxy Tab / Samsung initial boot image for about 1 second, and also hear the "boot chime"
-Then the screen goes completely blank (but you can tell it is still on with a little light showing.
-The four "hard button" lights will light up briefly a couple times
-Wait approximately 30 seconds to a minute (to be safe and give the tablet time to boot up - it is actually booting up)
-Tab the Power button once, to turn the tablet off (now the screen is clearly off)
-Tab the Power button again, and the tablet will be up and running as normal.
I am guessing the boot animation / images are failing in some way, but the tablet is booting up as normal.
I've just learned to live with it, because I haven't had a chance to figure out what's going on, but it honestly took me a good hour or so, and a few (unnecessary) flashes, before I realized the thing was up and running fine, it just need to have the button pressed on and off.
One final thing to mention; don't have the tablet plugged into anything. I seem to remember leaving it plugged into the PC didn't help (I think).
Hope that makes sense.
Cheers
Ed.
Has your situation been resolved?
I am in the same boat. What I have done to temporarily fix this was to Flash a ROM that uses Hemdall and it will boot as flukebu stated but only with the Galaxy Cubed ROM.
I cannot get the factory files to boot as you have stated.
I have continually tried to return to stock using the files provided on this forum and all "unbrick" posts.
While flashing the stock images everything completes and works well. The device reboots and the Samsung Splash screen appears. Once it appears it disappears and scrambles the screen. I believe it then goes into a bootloop which easily enough I could access factory recovery to correct but when I do attempt to access factory recovery the screen is as posted above (black but illuminated).
Once I flashed Galaxy Cubed ROM and it booted I hit the power button and the locksreen appeared. I can tell you I was excited but there are some issues with that ROM I have not tried to correct yet because my main goal is to return to stock.
Even with this ROM working correctly I have attempted to access CWM once installed to complete a Data Wipe and that does not show up either.
I would really like to find a solution to this I want to return to stock and not have this custom ROM running.

Have you found a resolution to this? Mine tab is doing the exact same thing as yours after the cubed rom.
I was on previously on stock GB rom and kernal (unrooted) and then used Kies to upgrade to ICS. Then followed the various guides on XDA to get root. Everything was fine for a few months except that the responsiveness on the note was laggy probably because when i used Kies to upgrade to ICS it was a no wipe and so everything i had installed on GB moved over to ICS.
Anyway, I read up on the brick bug and followed the guide here (http://forum.xda-developers.com/showthread.php?t=1857556) to use odin to flash kernal to HydraCore. Then rebooted into CWM, wiped data and cache and then installed Rocketrom v12. Reintalled all the apps from google play. Then used titanium backup to restore the data only of various apps (the only system app restored was internet (bookmarks)). Rebooted phone and everything was still fine. Then after booting up and was running a few apps (eg whatsapp) to make sure the data had been restored. Then noticed the screen started to flicker....then after about 30 seconds the screen went blank. And now no response, cannot get into recovery, download mode and not recognise when i plug it into computer. Is this the infamous brick bug??? Or something else??? My battery was on about 40% so i guess its not out of battery....could it be that the battery has died (i am not using the original samsung battery).....pls help!!!!
the screen flickers and the phone goes off is a classic sign of battery drained to 0.. charge again while the phone is off and try to reboot again. i guess u should be ok

Thanks for ur tip. It turned out that the battery died flat out....bought a new battery and my note is back alive again! I was so worried it was bricked! Thanks again!!!
cool..
Did you try charging the phone whilst off?
Hello,
FYI; I'm running a Galaxy S i9000 with Slim Bean 3.1 (4.1.2) and semaphore kernel 2.6.5 (was 2.6.0)
So today I woke up my battery was a low at 5%. But everything was normal and had been for a long time. I fell back asleep as I have the day off.
Woke up an hour or two later and my phone was dead. So I put my phone into charge.
Came back about 40 minutes later, enough charge to boot the phone, check my messages, but as I pressed the power button it just went into bootloop. And it hasn't done anything but that since. Every time I try to turn the phone on, the Galaxy S logo appears, then semaphore kernel logo appears, then disappears and reappears and then the whole process repeats.
And I tried plugging in the phone again to charge, but every time I do, the empty battery icon appears, it disappears and reappears, then turns off and turns back on again to do the exact same thing.
So on and off charge, it won't do anything but repeat a few steps over and over.
I cannot enter recovery, cannot boot the phone, the phone does not respond to being plugged into the charger, but I can enter download mode.
So I started googling and trying to fix my problem.
So far I have tried:
- Several three button combos to enter recovery.
- Using ADB to enter recovery (but as the phone isn't on, this doesn't do anything)
- Pulling out the battery, putting it in holding three button combos
- Trying different batteries
- Charging the phone
- Flashing semaphore JB 2.6.5 using ODIN
So basically the phone is bootlooping; when in charge, charge looping (is that even a thing?); and won't respond to any attempts to boot into recovery or boot at all.
I'm trying to avoid just wiping the phone using ODIN and reinstalling from GB to JB (which I have done before, and know how to do).
I'm currently leaving it to bootloop until the battery is actually dead and then I'll see if I can try all over again. Doubt it though.

Flash it like you did with semaphore .tar,there's good chances your device will just boot fine as if nothing happened.
Such boot loops are a long unexplained story but if you want to use semaphore try 2.6.6 version if it matches your rom,I was having many cwmless bootloops like you had and it didn't happened anymore since this version.
Ahh thanks for the info
I just got impatient and reinstalled everything from the ground up so everything's okay now and I have semaphore 2.9.x on slim (4.2.2)
So I recently rooted and installed twrp recovery with cyanogenmods most recent nightly. It was running smooth as butter for about a week. The battery ran dead the other night so I hooked it up to a charger and it only charged enough to show the root boot and battery symbol. Then nothing it just won't charge.
Funny thing is, when I plug it in regularly I get nothing, but if I leave it plugged in, take the battery out then back in, I get the battery charge logo for a few seconds then again nothing.
Anything I can do to remedy, troubleshooting steps before I insure it?
Kernel and battery probably have nothing to do with it.
Did you install A kernel other than Cyanogenmods' built in kernel?
Anyways, to "unbrick":
Can you put the phone in to Recovery (hold all three "home, power, volume up", and let go when you see "recovery booting" in blue text. I'm assuming you have A custom recovery installed since you have cyanogemod on it.
You can work with it from there. Wipe Cache/dalvik or wipe data/factory reset to see if it comes back to life.
See if it goes in to recovery like that, than it can be saved.
There's also odin which will bring it back to stock like when you first got it. Using A Windows PC.

If you have troubles with this let me know.
I had an LG with the same issue of only showing the battery symbol, then shutting off. It's dead to this day.
Yeah I have team win recovery. I tried a few times getting it into recovery but didn't have luck.
I have only had my used Note 4 a week, but just wanted to say maybe your battery is going bad. I remember reading about some people having problems like lockups and not booting, only to discover the battery was causing it. One guy posted a youtube video about it
https://www.youtube.com/watch?v=-Q-4pYUxOsc
.
my galaxy note 4 (sm-n910t) caught in bootloop . i dont know what caused it. the phone simply restarts upto first bootscreen, ie upto 'samsung galaxy note 4' and then vibrates and then restarts.this process continues upto battery is down or i pull out battery.the phone is not entering to recovery mode but enters to download mode.
i have tried installing stock rom from sammobiles but it won't help.i have also installed custom recovery twrp but that also won't help to enter to recovery mode,
i am trapped pls help..
You didn't mention how you tried to install the stock ROM . Did you use Odin?
I just fixed mine with the same issue. I was able to boot into recovery and download mode but mostly download mode without bootloop when I had the usb cable plugged in. I used ADB when I could to boot into download mode, but the buttons worked too. Trying to restart the phone only lopped after the Google screen.
I followed several guides here to flash stock with Odin and wipe cache etc but none solved my boot loop issue. almost gave up but there is a video on You Tube that said the battery warping in the cause of the boot loop. The battery, after/during quick charge, may heat up and change shape causing the issue. Today I installed my new battery purchased on amazon and no more issues.
Now I am on stock and have to find a good rom.
If you do decide to flash back to stock there are a lot of good guides. You may find yourself stuck on the T-mobile screen for 15 minutes when booting for the first time but that is ok. If you still boot loop after installing stock and wiping cache I would try the battery.

hi OP,
did you find any solution to your problem?
Hello all. I'm also pasting this in the T-mobile thread in case it can be of benefit to someone. This is advice to use as a very last resort if you are experiencing the recovery bootloop issue AND you don't have the emmc failure bug. I had the recovery reboot, sudden shutdown with no warning, etc. issue for the past two weeks. I tried everything on Google and Youtube to fix my problem with no success. I flashed multiple stock ROMS and recovery tars (stock and TWRP) via ODIN, but nothing worked. Oddly enough, I never received the emmc error that I have read about. Also, in the few times that my phone booted normally, I even loaded the Wakelock Power Manager app, set it to partial wakelock and my phone STILL continued to bootloop. As a last resort, I bought a new battery, but the reboot problems continued in Android 4.4.4 Kitkat, 6.0 Marshmallow, 7.1 Nougat and 8.1 Oreo ROMS. Well, here is what finally helped me to get my phone back operational. I had a backup ROM from a previous install and a TWRP flashable version of the same ROM on my SD card (in case the phone did not stay on for the full restore). I put the phone into a ziplock bag into a freezer for about 20 min. (thankfully this time TWRP stayed on long enough for me to do the following):
1) copy all the files I wanted to save from internal storage to a computer.
2) performed a full wipe (Dalvic, Cache, System, etc. Like when flashing a ROM, but this time also internal storage. Note: Please do not wipe both internal and SD card, as you may have a difficult time trying to load the ROM file back on the sd card (assuming you don't have a card reader).
3) After wiping, I was able to restore my stock ROM backup (or you can just flash the stock ROM).
I can't be 100% sure, but I think my wiping internal and then flashing the stock ROM finally did the trick. Since this morning, the phone has been pretty much back to as it was before. In either case, I'm sharing this with the hope that it helps someone else.
