[Q] Auto boot up and stuck on Samsung Galaxy Tab 10.1 screen

Hi, I was trying to flash a custom kernel into my Tab 10.1 3G with stock ROM. The process went smoothly but when I restart it just stuck at the Galaxy Tab screen. It will even turn it self back on right after I shut it down by holding the power button. I can still access the recovery and download mode. Can I still save my tab?

[Q] Boot loader always be the old one

First , I'm newbie and not native speaker, so sorry if its a FAQ and my English.
Well, I use Xperia Active
I've unlock bootloader , Use KRsH Kernel ICS , Install Real ICS 5.2
Its fine, however, whenever I restart my phone, it boots with sonyericsson screen and turn to a blank screen all times.
If I want to enter to my phone, I need to fastboot with the KRsH Kernel ICS again.
Well what I want to say is....
Normally, my phone boots with Sony boot screen and then enter to my phone. But when I restart my phone, it boot with SonyEricssons boot screen and then turn into blank screen. If I want to get into Sony boot screen and enter to my phone again, I have to fastboot with the kernel again and it will boot with Sony boot screen. However, if my phone is restarted again it boots with SonyEricssons Logo.
How should I solve this? (It's horrible if my phone restart when outside my home)
Sorry I only partially understood but here's what I think ..
Logo + blank screen = kernel installed but no ROM installed .... Try installing kernel + rom again..

Well, ROM has been installed and can boot it with Sony boot screen and then enter to my phone. But when I restart my phone, it boot with SonyEricssons boot screen and then turn into blank screen. If I want to get into Sony boot screen and enter to my phone again, I have to fast boot with the kernel again and it will boot with Sony boot screen. However, if my phone is restart again it boot with Sonyericssons again.
PS. Sorry with my English
This always happen? I do not consider change rom?

Okay.. It seems there is a kernel failure.... Try another kernel such as rage ... If still not works then flash stock ftf ..

[q] boot loop

I have a samsung s3 I9300.
I was trying to install a mutlimod for CRT screen off. I installed with CWM but it got stuck in boot loop. My problem is I can access recovery but my usb port is not working due to hardware problem. So I want to get out of boot loop possibly without losing data.
Thanks
Reflash same rom without a wipe first, then factory reset if it still won't boot.

[Q] Xperia Sola with Slimkat 9 ROM stuck on blank screen after SlimKat Logo.

So i recently flashed my Sola (Rooted, Bootloader unlocked) with the Slimkat 9 ROM using Flashtool. It went smooth. When I booted the phone it was suck on a blank screen. I tried everything but the phone just wouldn't budge from that screen. It stayed like that until the battery drained out. Now no matter what I do, (charge it, try to get into recovery/fastboot, connect it to the pc) only thing it does is get stuck on the same screen.
I thought i would flash the stock firmware but then the piece of shizz doesn't boot into recovery so can't do that either.
Help anyone?
