I cannot explain it more and i am unable to copy and paste on here what it is i am seeing.
I have never had this problems with any files before and i cannot figure out what i am doing wrong this time

Ok, now I understand, you get files like on the pictures I posted, right?

Then rename the .zip file to .ftf. If you do not see the extensions on your PC like .txt, .doc, then go to Control Pannel > Folder Options > View and uncheck "Hide extensions for known file types" then Apply and go to rename the Zip file to .ftf and you are ready to flash.

Not really, is for C6903 only and I will not recommend to cross over. BTW, to avoid the IMEI lost in the case to downgrade directly to .534 with other Firmware just exclude "Baseband" and all will be fine.

If you're planning to upgrade anyway you'll get your IMEI back, so just root it and upgrade.

Thanks for the post.

No that did not work for me. Downgrading to .534 excluding "Baseband" too resulted in loss of IMEI. Tried a few times and failed miserably. I feel I will have to downgrade to .257 before getting to .534 as this is the other suggestion to downgrade without loosing IMEI. But the issue I am facing is that the flash tool does not seem to recognize the .257 ftf file that I downloaded. Not sure why. So planning to download the Global .257 release and then try downgrading to .534 so as to get to rooted status.

I would be upgrading to the latest firmware but need a rooted device. Rooting 4.3 without unlocking the BL is not possible. Hence want to take the round about way of getting this achieved.
