[Q]Phone stuck while transfering files PC > S2 (via USB) - Galaxy S II Q&A, Help & Troubleshooting

So I got kinda unpleasant problem... I was transferring files from PC to my phone via USB and it got stuck (phone), PC was still showing disks of phone but I was unable to do anything with them. The only way to wave my phone up was hard-reset (removing battery) and after the last hard-reset phone had stuck on the boot screen:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
But I can still enter the Recovery.
Any ideas how to fix both this problems without making changes to phone and microSD card memory (I just can't change it).
Btw, I'm using CM 10.2 20131117 Nightly
P.S. I attached photo with errors which I got on PC when phone stucks

You can try re-flashing your ROM again first, without doing any wipes. If that doesn't help, go into recovery and wipe cache and dalvik cache, fix permissions, then reboot and see. If that doesn't help, do a factory reset.

One guys said that this file transferring stuck happens because CM Kernel is bugged and this stuck can be avoided by not allowing phone screen to "sleep" (I think there is a setting for it) while transferring files - is it true?

Am sorry, but I really don't know. I have never used the stock CM kernel much.

The stock Cm10 kernel and also slim kernel has got some mount issue's when using 'USB Mass storage' mode, hence its advisable to use 'MTP' mode instead
If ur able to enter recovery mode then u can reflash the rom and see, if not possible to go to recovery then just ODIN flash 'Stock CM10' kernel if one is available or else u can use the 'Philz' kernel to flash through ODIN and use its recovery to flash a stock CM10 Kernel Zip file

I changed connection type from USB Mass storage to MTP, but now my phone does not connects to PC at all - what the hell? :s
P.S. I can't reflash rom, because I need to keep my phone memory safe for a while :|

@GeoPrey One thing I can think of is a dirty flash, I've done this before.
Just go ahead and wipe the Cache and Dalvik then flash the phone with the rom again.
No Factory Resets or w/e.
Not entirely sure if you still keep your text messages though.
But everything else is a go-a-head.
You can also push files through ADB in recovery if you have the Android SDK installed.
