[Q] How do I Fix My Rooted Blu Studio 5.3 Stuck in Boot Loop?

So I rooted my Blu Studio 5.3 FTW. Titanium worked wonders backing up everything, but I messed up using Rom Manager to fix permissions. Now the device boots up to the BLU splashscreen, shuts off and gets to the splashscreen again and again and again.
I'm past the return product window so I can't send it back. Any advise is welcomed. Thank you.
Need help too
Im in the same boat but my device stuck in BLU products logo mode and going no where till the battery die out.
I have tried the following but not work for me, hope its work for you.
-plug and charge your Blu.
-press and hold Volume Up button and press and hold power button until the an exclamation mark inside a triangle with an Android icon image come out.
-hit the home button.
-scroll down by using the up/down volume button to pick your option choice
- hit the second button next to home button to active your choice.
If you reboot your device and everything back to normal, congrat.. unfortunately mine still stuck in the logo mode no matter what i try .
If anyone have any knowledge regarding this problem, please share... Thanks in advance

[Q] Galaxy Nexus stuck on X

Hey People,
I rooted my Galaxy Nexus and downloaded rom manager, from there i downloaded a rom for Jellybean. The phone rebooted and is stuck on X glowing logo for long time. I went into Recovery mode but i get the exclamation mark with android symbol (at this point i try to press Volume up and down and power button and nothing happens). I'm so lost on what else to do. I have no way of getting into the phone to the hard reset. I would be glad to get the phone back up and running.
Any help would be great.

[Q] Please help,Getting Stuck on fastboot and recovery

Dear experts,
Phone model: Karbonn A9+
Rom: Custom Rom Hyperion Skyfall
When I hold the power button, the phone turns on and off, No problems with that.
However, when I press volume Up+Power, I get a green screen saying FASTBOOT at the top left corner and that’s it. Nothing happens from that point.
when I press volume Up+Power, I get a green screen and holding the buttons past that I get a red screen saying RECOVERY at the top left corner and that’s it. Nothing happens from that point.
However, when I press volume down+Power, I get a black screen saying ENTRY QPST DOWNLOAD at the top and that’s it. Nothing happens from that point.
I have to remove the battery to turn my phone off.
Moreover, I tried a factory reset erasing internal and external storage, after erasing when the phone is rebooted and gets stuck in the start-up screen. I removed the battery and powered on the mobile ,no problem at all the phone turns on but not resettted.
What I did?
Tried to install latest CWM through recovery, updated it but I pressed something instead of restart your device.
What should I do to make everything work again? I am a noob in Android, please be extra patient and illustrative
Many thanks in advance
