Boot into recovery, wipe cache, dalvik cache, format /system and reflash the ROM. If that doesn't work then factory reset.

Got it, thanks anyway

[Q] I am Bricked....i think

Ok, So i rooted my T-mobile G2x 2.3.3 and there were difficulties when i flashed the Cyanogen 7mod. The Rom worked but the only default was i didnt get data. Like i couldnt even get Edge. The only way to use internet and stuff was through wifi. SO then i reflashed it thinking it was a bad flash. But when i reflash through rom manager it gives me the option to downoad with google apps. so i clicked that option. It downloaded fine but on the reboot it stayed stuck on the 2nd LG screen. Am i bricked or if anyone can help id appreciate it alot.
U can't do it via rom manager. U have to flash recovery using nv flash, then u can try to flash custom rom. Remeber to wipe data and format system before flashing any rom.
U r not bricked yet
Check here to nv flash the cwm

Did you flash CWM via NV Flash. If not, do that. Then boot into recovery by holding down the power + volume down keys until you get the second boot logo. Then wipe the dalvik cache and the regular cache. That is usually why a phone refuses to boot.
Also, if your phone turns on it is not bricked. Bricked means when you press the power button nothing happens at all. You can be soft-bricked like you are, but it can be easily fixed. Nothing to panic about.
I did all of that im sorry if i gave you info wrong. Like i cant do anything it turns on but goes to the first LG screen then goes to the new LG screen with the blue streaks and it stays there. Then when i try to go into CWR it shows the LG with a blue and black loading bar below then shows as if its loading something then it just goes back to the blue LG screen and im stuck there.

You have stock recovery on the recovery partition, not CWM. You MUST flash CWM onto the physical recovery partition using NVFlash with the One Click flasher. You used Rom Manager and that doesn't install CWM onto the recovery partition. Once you have CWM properly installed you can enter recovery and revive your phone.

@OP, this is is correct. Use tga gunmann's nvflash tool from the development section. The process is super easy. Just make sure to follow his instructions closely. Just fyi, most people get errors during the nvflash process because they don't install the apx drivers appropriately, so take your time and read the instructions carefully.

Start off by wiping cache and then go to Advanced and wipe dalvik cache. If you still can't boot after that then try a full factory reset.
Just remember the first boot after wiping dalvik cache can take several minutes as android rebuilds the dalvik cache. All subsequent reboots will be MUCH faster.

Did you do as phburks said and go into advanced and wipe the Dalvik Cache. Most issues of not booting are related to the Dalvik Cache not being wiped after flashing a new rom. That is essential to getting your phone to boot again. A factory reset DOES NOT clear the Dalvik Cache.

Boot back into cwm, go to Mounts and Storage, format /system and then reflash your rom.

Could be a bad download. I'd try downloading again. Use your computer to download again and save it to your microsd card. Then reinsert the sdcard, boot back into cwm and try again.

Yea the rom. Is it cm7 that you're wanting to flash?

The reason I ask is that with cm7 you have to flash 2 separate zip files. First you flash the actual cm7 zip which installs the rom and then you flash the gapps zip which installs the Google apps (market, gmail, etc). Make sure you have both on your sdcard and then flash the rom first and gapps second.

Im glad you brought that up because when i first flashed Cyanogen i did also flash gapps but after i flashed gapps thats when i wouldnt get data. Do you know the reason for this? or was it could have been another bad flash?

Not sure. I'd just play it safe, re-download both, wipe data, and reflash both. Sometimes its hard to determine which step went wrong and its best and quicker to just start with a clean slate and redo everything.
I wont be able to post for a while so good luck.

black screen

Hi,
I´ve tried to use "root live logcat". This app is supposed to show logcat during phone boot, but I got black screen instead. Phone will boot but I´d need to know how can I remove black screen.
I tried to uninstall root live logcat and copy new bootanimation.zip into data/local and system/media but it didn´t help.

If you select wipe data/factory reset...you will lose everything that isn't saved to your USB storage. You should be fine with just flashing the ROM without the data/factory wipe. Just make sure to wipe your cache and Dalvik!

What betoishly says. Wiping cache and dalvik cache does not affect your apps/data. Only if you do factory reset you wipe everything.
For the record, this solution did not work. Any other suggestions?
After wiping the cache partition and Dalvek cache, the phone continued to boot with a black screen. It then went to an "Android is upgrading..." screen and Optimize every single one of my apps (128). Nothing was messed up.

Just getting the logo and a black screen after an update

Samsung Galaxy S2 i727 Skyrocket.
I recently updated to a 4.3 rom.
It booted up and I just got a message "Unfortuanately, Nfc Service has stopped. Blame Tyler."
I couldn't get the message to go away and the only thing I could do was a hard reboot.
Still same issue.
Rebooted into Recovery mode.
Factory Reset, wipe cache partition, format /system, wipe dalvich cache
Restored an older rom.
It booted up with no issues. But when I rebooted, I just get the Samsung logo and then the screen goes black.
I even tried Factory Reset, wipe cache partition, format /system, wipe dalvich cache and installed a new rom from scratch.
Same problem.
I have no idea what to try next or why this is happening.
Any help or comments are welcome.
Thanks

Sometimes if you get stuck on the boot logo and it never fully boots, simply clearing the cache and dalvik cache in CWM or TWRP can fix it. (Might throw in fixing permissions as well.)
