[Vibrant Q&A, Help & Troubleshooting] DrgnAK:
Edit: Not a bootloop. It just shows the vibrant screen and shuts off after that. It turns back on sometimes because I still have my finger on the power button. I am still unable to get into recovery.

Edit 2: After finding Eugene's Rom, I was able to flash and get a working Froyo Rom, and then I flashed to stock. I am unable to access both internal and external SD. The version of Eugene's rom I used didn't have selectable recovery menu options while the standard Android recovery can't even access SD anyways.

Edit 3: I was able to follow Cyanogenmod's guide to install Cmenard's kernel using Heimdall. I also reflashed the Froyo bootloader. When I turn on my phone, it simply stays on a screen that says "Overstock Smaller. Lighter. Faster." and it does nothing else. I am unable to get into recovery with volume up+down+power and releasing it after the screen flashes.

Edit 4: I somehow got Overstock to work. Turns out the recovery mode was just the e2 recovery. I need some way to get a recovery that works with an external SD card I believe...

Edit 5: Apparently you only make yourself look like an idiot when you find out that you didn't have the update.zip file on the external SD (or the files disappeared...)

Edit 6: And after I managed to get update.zip/CWM to work, everything worked out except for the vold.fstab thing I had to modify like 20 times before I got it to use /sdcard, but everything is good now and I'm running Android off of my 32 GB sd card.

Okay, I own a Vibrant NOT 4G and I currently am stuck in a bootloop where Vibrant appears and goes away. When plugged into the wall, the battery circle appears and disappears over and over. I've tried flashing to stock with Odin3 across 2 computers with different cables each time with and without auto reboot and repartition on but alas, I am only able to get into download mode and not recovery so far. I have used these same files (The pit and the T959UVJFD.tar) to return to stock from both 2.3 and 4.0 custom roms as well as the same drivers before so they all should still work. I am only able to get into download mode, using Power+Volume Up (all other combinations, timings, etc don't work anyways). I'm guessing I still have the Gingerbread bootloader and not a Froyo one, especially since I still have the GT-I9000 logo when I turn on the phone. All the threads I've found relating to not having recovery mode but download mode all say to flash back to stock, but clearly that's not working.

If I have to flash back to a Froyo bootloader, I'll do it, but I have not yet.

IF this information matters, I was using SlimBean's latest version prior to this ordeal (Android 4.1.2 based) and one day, while I was listening to music with the screen powered off, I turned on the screen and all I had was a black screen. I decided to just remove the battery and after that, my phone would only be able to boot into Semaphore's CWM. At this point, I was unable to access /data to flash anything from my internal SD, so CWM opted to look at my external SD for files. I put the same ROM files on there and proceeded to attempt to flash but it refused to flash as it was unable to mount the internal storage (it said error mounting emmc or something like that) to flash. After that, I decided to use Odin3 to flash to stock... and you know the rest of the story.

My brother has the same phone which has gone through the Unencryption Successful problem and he revived it by booting Android off of his SD card. He tells me that he had the same indicators where the screen only powered on to a black screen and so he turned off the phone, but in his case, he was able to turn it back on and was welcomed by the Unencryption Successful screen while I got nothing at that point. I could only get into CWM and that was it. I'm considering the possibility it is something like Unencryption Successful or that the internal memory is just shot.
