[HELP]Samsung SII I9100 Stuck on Pre boot screen. - Galaxy S II Q&A, Help & Troubleshooting

I need help for my SII stuck at Pre Boot screen (Samsung Galaxy SII GT-I9100). The phone has the original FW (Italian no brand) and , if charger is connected, I see the battery logo with a grey circle inside. The battery indeed is charged. The phone can enter only Download mode, no CWM. Untill now I do the following:
With ODIN 3.09:
- Flashed last official Samsung Firmware. The flash was successful, but same problem.
- Flashed CWM Cynogenmod in order to get recovery mode and make a full wipe. The flash was successfull but I can't enter CWM, only Download mode is enetered.
- Back to original FW
It seem that the phone has some "bootloader" problem. Please help! Thank you in advance!

Tried this?

Samsung Galaxy Note 10.1 n8010 stuck on Samsung logo

Hi Everyone,
I'm experiencing a problem with my tablet. My tablet is not rooted and I didn't even install a custom firmware.
The problem started after my tablet was on and charging, I just unplug the USB cable and it restarted and stay stuck on Samsung logo.
I tried to install recover mode via Odin (several versions of Odin and TWRP) and new firmware version (also via Odin) but without success. Well Odin says that was installed successfully but it won't start recovery mode after it's installed.
I don't know what to do anymore... can anyone help me.
I thank you for any help you've got to give me.

Download the latest Jellybean firmware and flash it via odin. It should work fine.
PS: Use odin 3.09 or 3.10
Use odin and download Samsung rom or cm
