I have a SGH-T959P. I flashed the SGH-T959V firmware on it and then the SGH-T959D firmware. The latter was really slow, so I decided to switch back, but upon switching back, the phone shows the T-mobile logo and boots directly into the recovery menu. I have tried reflashing various ROMs, but they all behave the same now. I have CWM 3.0.2.8 installed. I have tried clearing the cache, format, etc to no avail. Does anyone have any ideas?
I got it fixed. I flashed http://forum.xda-developers.com/showpost.php?p=38748801&postcount=280

Okay I was running the older Thunderstick rom and I wanted to try out the new version. I downloaded only the update though and flashed that without realizing thats what I had done. So I am now stuck at the splash screen and I can't do anything. I have wiped data, cache, done a recovery, and tried to pull the battery as well. What can I do to get it off of the splash screen?
I go into recovery via the adb port if anyone is wondering. But even going back to the old recovery I can't get past the splash screen. I even tried another backup as well but to no avail.
Fixed the issue. Rebooted into recovery mounted SD card and put a new radio file and new rom on the card and flashed both over. Working now.
So I hate starting a new thread, but after searching for a day I have not been able to fix this issue.
I was running UnNamed v2.1.1 and wanted to update to the newest version. Following the instructions, I booted into CWM, wiped data/factory reset, installed the zip from my sd and rebooted. It worked fine, but I lost all my contacts which were on my SIM card (I was dumb and didn't back them up).
When I had previously updated I still had my contacts so I figured they should still be there. In an effort to find them I booted into CWM mode again and installed CM9 Nightly from my zip card. Again it booted fine, but still no contacts. I decided to go back again to UnNamed (wasn't a fan of CM9) and then I ran into issues.
My phone got stuck in the boot animation screen. I waited 20 min and nothing. Then I followed creepyncrawly's guide for returning to stock. My computer said "PASS" but when it rebooted it said "failed to mount /data (Unknown error: 0)". I turned off the phone and tried again and it seemed to work, but now my phone is still stuck in boot animation screen.
Any ideas how to fix this?
Reflash stock rom through Odin. But I would flash a cwm kernel through Odin, boot into recovery, and flash a rom.

Don't know what is installed with cm9, or if flashing cm9 repartitions, but you can find bootloaders, param.lfs and PIT and complete stock UCKH7 packages in the Download Repository linked in my signature.
Troubleshooting without enough information is only a shot in the dark. I often see problems with param.lfs associated with boot loop. Your error message not being able to mount /data partition suggests PIT. Just some thoughts to start you on the way.
Finally fixed, thanks for the suggestions. After flashing the stock rom in Odin it still wasn't working. I was wiping factory/data before flashing, but for some reason when I wiped after flashing it worked fine.
Hi Friends,
Model Number - GT-P7510
I recently rooted and installed the CM9 ICS nightly rom using the noob video instructions (This included rooting with Odin, installing CMW recovery 4.0.0.4, then I flashed the ROM cm-9-20120624 Nightly and finally flashed GAPPS-ics).
I over clocked using the CM9 settings and everything worked perfectly for about a week, it was great. Then it just crashed while I was reading my email and began to bootloop. After reading for similar errors I rebooted to recovery and tried wiped the cache and dalvic cache, I wiped data and factory reset several times but nothing worked, always the same bootloop. I re flashed the same ROM and still nothing, after a while the boot screen would simply freeze instead of bootloop.
Then I connected to my PC, and did this to no avail. In fact it simply added to the problem by adding a yellow warning triangle while attempting to boot so I did the Oden thing again like the first time I rooted however I installed CMW version 5.5.0.4 instead thinking it might help but it hasn't.
One last point, when I attempt to wipe data/factory reset the tablet seems to freeze and attempt to reboot rather than say something like "success" as it would during a cache wipe. This maybe normal or it maybe the problem! who knows?
On that point, I would be very grateful if some of you could help get me to the point when my PC recognises the tablet so I can reflash a new ROM.
Thanks in advance,
Karl
I once got the same problem. The only thing that helped was to flash back the stock rom via Odin with the pit file. And don't forget to do a hard reset after flashing the rom. I'll just stick to the stock rom until the official update is getting released.

Questions go in the Q&A section
I think the best way is still to do factory reset, go back to the stock ROM first and try custom HC ROM until the official ICS is released.
I am afraid that my phone is dead. I had custom Rom on it, Portal rom, I decided to try the Simplistic rom, but it didn't work very well. I reflashed Portal from CWM, but I get an error message at boot saying "messaging has stopped", there's no signal on the network either. I tried to reflash, but the same thing happened. I wiped and did a factory reset. Same thing.
I then flashed Simplistic again and it works. I just don't like it. Another try on Portal and Alliance both fails, the "phone" does not start and shows no bars. Simplistic once again boots.
I then decided to go back to stock and downloaded the latest stock ROM for Nordic Countries and flashed it with Odin. All went seemingly ok, and I rebooted. It hangs at the bootlogo and never gets passed.
I then flashed cf-kernel to gain access to cwm and tried portal again. This time that also hangs at bootlogo.
So what to do? What can I try to get my phone to boot again?
Edit: I tried to flash Simplistic again and that still boots fine. So wtf?? If I didn't know any better it would seem that Simplistic rom as done/installed something so that the phone now only works with that...
Help anyone?

In your own case, when you want to flash either portal or alliance ROM, follow these steps:
- boot to CWM recovery
- wipe data / factory reset
- wipe dalvik cache (under advanced)
- format /system (under mount and storage)
- flash ROM ( alliance or portal)
- fix permissions (under Advanced)
- reboot phone.
Ps: the reason why your phone did not boot after flashing via Odin was because you did not perform a factory reset in recovery after flashing

Hi all,
New to this whole rooting and flashing thing. I'm not as good with computers that one can hold in their hand.
Anyways, I'll try to explain this stew of issues that I have
I'm running CW Recovery (6.0.2.3) in conjunction with SlimBean (dtt 4.2.2). One day, in a far away land, my phone prompted me to update Slim. That was all and dandy because I've flashed roms from zip files before. When I tried to do that, the process was aborted and I was given a slew of error numbers that made my brain hurt.
So, I tried to start fresh and clean, like the cilantro that chipotle puts in our burrito bowls. I tried a factory reset using the CW Recovery mode so I can re-root now that jellybean is 4.3. After I wiped the cache and data/factory reset, I rebooted the phone. My phone still boots into Slim and uses clockwork for recovery mode.
Essentially, how do I de-root my phone or factory reset it to the settings that I had from day 1?
UPDATE: I just tried flashing CW Recovery from 6.0.2.3 --> 6.0.4.7. After flashing it, I rebooted my phone into recovery. Now I'm getting a never-ending boot cycle. The samsung logo pops up along with the little blue text "recovery" at the top, then shuts off and repeats that every 3 seconds or so. Methinks I broke it
Thanks
