I was originally on a CM rom but decided to give a stock based rom a try and it flashed and booted successfully. Now I want to go back to CM and flashed another CM rom but now it won't boot. It flashes the LG logo for a half a second and then just hangs at a blank screen. Any ideas?

I encountered something like that a while ago. I solved it by shutting it down (hold power button for 20 or so seconds) then let it sit for about an hour.. It booted up after that. Hopefully it works!
If not, you might have to lgnpst

Please provide more information so we may better help you...
Which AOSP-based ROM did you flash before you encountered the problem?
Did you wipe everything before flashing?
Did you flash anything in addition to the new ROM?
Are you still able to get into TWRP Recovery?

Yes, I'm still able to get into twrp but restoring now fails.I went from BeanStalk to Vectus Slim to NexOGen to SuperNexus (never booted), now I can't flash any stock or cm based rom without it hanging. I always wipe system, cache, dalvik, and data before flashing into another rom. I only flash the rom and gapps.
do you guys think if formatting the card and sideloading a rom might help?

I don't believe I have. I never had any issues until now.
I found this thread which seems similar to the problems I'm having. It seems like formatting data could fix the problem. If not, i'll try LGPNST and flashing teenybins next.
Thread: http://forum.xda-developers.com/showthread.php?t=2342985&page=2
I believe flashing a teenybin was recommended for CM so occurances like the LG logo to black screen would not occur. This happened to me, so I know by experience. A lot of people dont do it because it seemed to complicated and flashed CM and nothing happened, most likely it will happen to them sooner or later.
Good luck with the teenybin, I'm pretty sure that will solve your problem, as that solved my LG logo to black screen problem months ago

Did not know this, thank you very much. Formatting the data and flashing a new rom via adb worked by the way. As you suggested, I just flashed the original teenybin with LGNPST and everything went smoothly. Hopefully, I don't have to run into the logo black screen issue again. Thanks!

So I have been trying to flash CM9 for the past couple of days, at first it worked just fine but I forgot google apps, so I went back to recovery and flashed gapps. After that it wouldn't leave the boot screen. I used odin to put a stock ICS rom on, then flashed clockwork and now every time I try to install cm9 It just stops on "installing." Did I miss something very simple and obvious or what?
How long are you letting it sit on "install"?
I've tried several time's usually only a few minutes, but at one point I left to the store and came back like an hour later and it was still on installing. Had to pull the battery every time, then I have to use odin because I can't get into recovery.

You need to follow the instructions to the letter .... and when you get it flashed if it don't boot go back into stock recovery and wipe data and it should boot

So this is kind of a unique issue i'm having. I have the I-747 on AT&T and flashed AOKP rom (it was taking too long to get JB). It worked for about 3 days and then got stuck in the android boot screen (used the rom feature to get rid of the pink unicorns). after that, I booted into recovery and reset my phone, and it worked again for a few more days, then it wouldnt boot again (I dont believe I changed any settings between the boots). After this time, it wouldnt let me boot into recovery and would only boot to the android start screen and stop. I used odin to flash the stock rom, which only took me to the 2nd samsung boot screen and stopped (after the AT&T splash shows up). I looked online and saw someone say try CF-root using odin, tried that and it didnt help. Then tried using a custom kernel siyah s3, and now it will only show the initial samsung splash screen before turning off again. Any suggestions here? I figured I'd stop researching since i dont want to really mess up my phone worse than it already is

Thanks guys! So I used odin to flash the stock boot loader and stock rom, but it is still hanging up on the 2nd samsung screen like it initially did (the one after the AT&T boot animation). Any other ideas on what could be the cause?
How long is the hang? Sure is just not the 1st initial boot of the new rom?

The first boot can take as long as 5 minutes sometimes. So, if you haven't waited that long, then try out some patience. Otherwise, try booting into recovery (stock now) and factory reset.

I have this same issue. I have restored to stock rom and it does the Samsung boot, then AT&T, then it goes to Samsung pulsating with a blue pulsating LED.
I have left it in that mode for at least 15 minutes and it never boots.
I can still get into download mode.
Thanks in advance for any help!

I let it run for 2 hours (left the house came back and i was still on. And phone wont boot into recovery at all ( i tried many times, but it just boots normally and skips recovery until it gets to the 2nd samsung screen, then stops there).
I dont know if this is relevant, but while the phone is off and plugged in, i can still see the battery meter and the Green LED (so i'm guessing it's still working, it just wont boot)

I went into recovery many times before, I'm definitely hitting the buttons right but it still wont go into recovery, it just tries booting like normal. I can go into download mode easily, but that's it.
jbizz, did you start getting this error after flashing AOKP rom also? trying to figure out what could have caused the issue in the first place
I'm not really skilled on these things, but I once had a similar issue with my phone not booting and had to end up using Kies to emergency restore it. Odin wouldn't recognize my phone but kies would.
Although I think my issue with odin may be stemming from my computers usb ports...

Fixed it! What I did was go into Kies software and did a firmware upgrade instead of trying to flash from odin, then put it in download mode instead of recovery, but it still worked. Thanks for all the help, guys! guess it's time to move to a CM based rom?

Sure, I'm doing this largely from memory since I mostly figured it out by throwing stuff at the wall to see what sticks.
Open Kies->tools->firmware upgrade and initialization->enter model name then serial number (they're behind the battery) -> put the phone in download mode and plug it in. it should take care of the rest.
Fair warning, this will fully wipe your phone, i lost all my pics (thank you google+'s instant upload or i'd be PISSED) and titanium backup (there goes my 3 stars on every level in angry birds and great scores in temple run), but at least you get a phone that can function as more than a paper weight, right?

After you flashed stock on Odin did you do a factory reset? Try that. It should solve your problem.

I tried that. It gives me the same thing. It skips the welcome screen for the tw jb roms and then the system manager randomly pops up. After it pops up, I get these random texts shown in the picture on my home screen and sometimes I can't pull down the notification bar when that happens. It was working fine yesterday though.

Never mind, I found a fix. Just had to restore back to my old ics touchwiz rom and delete root. Then I used kies to update to jellybean.
so I don't know how it happened
but over the past couple weeks I've had a lot of trouble with my phone
I didn't notice any issues until I flashed Skynote
it started out as just my computer not recognizing it when connected via USB
but problems have escalated further now
for some reason if I try flashing touchwiz roms 1/2 the time TWRP crashes while doing it and if it doesn't it constantly hangs up during flashing(it took me almost 1/2 hour to flash ultimate internation rom last night)
If I get a rom running the phone is constantly hanging when going through the settings menu.. or if an app is installing it will lock up totally for like 5 seconds
I've formatted thru twrp, I wipe the system every time. I've tried countless factory resets
nothing seems to be helping
anyone have any idea what might be going on?
Probably something corrupt or misplaced. Flash stock to using odin. That should fix it

I have faced similar issues twice after changing a rom. The only way back to stability was to odin a stock firmware on to the note II and then to re-root, re-install a custom recovery and reflash the rom.

Try CWM recovery, not twrp....I never use twrp, , always hearing issues with people using that recovery method...Some phone's just don't like it..lol

I seriously can not figure out what I'm doing wrong. I'm going to be giving away my Epic since my friend broke his phone and I have the S4. However before that I want to install TWRP and the latest KK rom but everytime I do I brick the phone and have to restore it back to EL30 or FC09 and start over. I done this 4 times and I still can't get it to work properly. It roots fine but when I try to install a later rom or TWRP it doesn't work. Can someone help me out?
BUMP
Is there no one that can help me with this problem? I really want to get this cellphone working so I can give it off to my friend.
wich rom and wich twrp?
The epic 4g custom roms all have a recovery that goes along with the rom. The blu kuban rom has always been stable for me and if I recall correctly it has twrp along with it instead of cwm.
On second thought, are you talking about the sprint s2 non slider or the slider one?

It's the Sprint Epic 4G with the slide in keyboard. SPH-D700 if I recall.

Rather than forcing TWRP...follow the instructions in this thread choosing MTD choice and then use the CWM recovery that will already be on the phone to flash your choice of ROMs. TWRP does not work with everything on this phone.

This is the guide I followed to root. (As well as qbking77 guide) I tried both MTD and BML once I failed and it's the same problem. Once I flash your deodexed rom it works but if I try to flash a different rom it doesn't work or at least one of the latest rom. I know in Schism rom it said to update to the latest TWRP or CWM but when I try with CWM it doesn't work and if I try to install TWRP I end up bricking the phone which I have to restore again.
Alright I followed everything on the thread and used MTD again. I checked and I'm fully rooted. Now I'm gonna try to flash the rom I'm trying to flash. I'm assuming I should Wipe before installing the rom right? Since the stock and custom build are different.

It failed again. I did not wipe and for some reason it still does not work. Once I install the Rom from zip it says Checking State of BML/MTD and it reboots once it reboots it just stays on the Samsung Cyanogenmod screen. I waited for five minutes and nothing happens. Also sometimes when I do try it just stays in a black screen with the buttons at the bottom glowing.
