Firmare upgrade encountered an issue.Please select recovery mode... - Galaxy S II Q&A, Help & Troubleshooting

Hi all ,
i had installed an official galaxy s2 4.1.2 rom ,and it worked perfectly. However ,all of a sudden ,it looked like it automatically updated ,and got stucked at "Optimizing app 2 of 9" or something like that . I waited for a while ,when nothing changed i have pulled out the battery and tried restarting it. So it just showed the samsung logo and didnt boot. When i tried entering the recovery mode ,it just stucked with the green JB icon..basically i could just login to download mode . I have tried flashing the rom again via odin ,but it got stucked at "factory.img" and eventually wrote "FAIL" in red . I have tried numerous roms ,stock roms but nothing seemed to work.(same problem). Now when i power up the device ,it says "Firware upgrade encountered an issue. Please select recovery mode in Kies and try again." I have tried flashing just the ClockworkMOD recovery ,but it also got stucked at "NAND Write Start!" and did nothing...
Another thing is ,that im afraid that i was running a really low space on my internal storage (16 gb) and im afraid that this is why nothing can be installed on my device..Could it be possible?
If so ,is there some way to access my storage somehow without booting up my device? Or in a worse case , how can i wipe my storage before the odin flashes?
Thanks in advance.

Try another odin version/usb cable/usb port/another pc/laptop.

I have tried different usb ports ,different computer and also different Odin version.
When i am trying to flash a complete rom ,it stucks at factoryfs.img,and if i am flashing just a kernel ,it stucks at "NAND Write Start" ...I have only one usb cable though , but it should be working fine because i was able to transfer files with it not long ago.
Could it be that lack of storage on my internal card is causing this kind of problem...?

Which sgs2 model do you have? (I9100, I9100G, I9100M, I9100P, I9100?, etc etc etc).
Which specific rom/files did you flash? (link)
These are the questions you should have answered in your first post prior to writing anything else. Without this info anything else you write is useless.
Can you provide screen shot of ODIN before clicking flash button.

Thanks for reply ,i will post soon the screenshot ,just need to gain one more post (10 or more
for posting screeshots.

I have a I9100 model and i tried a bunch of official roms for that model from different countries ,which did work for me in the past for sure ,because some of them i have kept on my hard drive.
Anyway ,here is the download link : http://www.sammobile.com/firmware/?page=3&model=GT-I9100&pcode=PTR&os=1&type=1#firmware
I am downloading the 4.03 version PDA I9100JHLPC CSC I9100PTRLPD
http://www.hotfile.com/dl/177046516/65bd55e/I9100JHLPC_I9100PTRLPD_PTR.zip.html - actual download link
This is the screenshot of my odin before the flash :
And this is the image after the flash ,where it gets stucked :

Try flashing jb leak (phone, csc & modem, nothing else).
If that doesn't work, we could be talking nand corruption.

Thanks dude ,i will try it now.
What does it mean ,"nand corruption"?

device's internal memory corrupted, can't write/read it.
That's what partitions (pit files) are for.

Well ,that didnt work as well...same scenario. I tried flashing just the rom via pda ,i tried all 4 files at the same time ,i tried just the pit...always got stucked.
I guess i will take it to my mobile service provider ,unless there is something else i could try?
P.S - If my internal card is corrupted , will they be able to see i flashed a custom rom and rooted the device?

Lol, don't just flash pit files.
Read something about pit files first. There are a lot of threads regarding this topic.
Still stucked in boot right? no back up whatsoever?
Flash different siya's versions, see if you can get to recovery. When you do, try flashing a rom via CMW.
