[General Questions and Answers] breakmycurse:
Hi guys.I am new to forum so i didn't know where to open this thread.Also i have checked internet for a solution but never seen a dumb thing like this before in my life.So even google search engine couldn't help me about that.

One of my friend has purchased a device from dubai.it is an original device of i9505 with snapdragon 600 processor.I am personally using an i9500 octa version btw.my friend told me to check his device after he had problems with gsm service+wifi for 3g doesn't connect(or connect and drops fast) so i went to check his device.i have used some system info tools and benchmark softwares to identify the device is ok.but NO IT WAS NOT OK.all of the system info tools says that the device is i9500 but it has snapdragon processor.some idiot somehow managed to write i9500 rom to i9505 and it is working with problems.i have checked camera both ok frontal and rear.and other device properties working good as well.i should expect that it should even fail to boot but somehow working with great deal of no phone service+3g problem(phone service sometimes work i really don't know how it works or how it fails).

So i decided to make things right.Which is put the right original galaxy s4 i9505 rom to that device.i have checked sammobile and found germany version of kitkat.

general info : device is rooted.it says it has Wanamlite rom 4.2.2.

My Try list:

1)downloaded odin 3.09 and followed the instructions.(used the official rom given from sammobile.)and put the mobile to download mode(i couldn't do it with volume down+home+power button cos it is not working)but i thought i was lucky cos that custom rom had an option when i push the power button/restart/ it says there is a download menu so i choose that to put the device to download mod.after that i was hoping odin will do the job.but it FAILED DUE TO WRITE PROTECTION ENABLED on device.

2)i tried to setup cwm recovery to device(which i figured out later it was already on device but i didn't know it was there).downloaded rom manager from playstore.and i thought it would work.rom managers says i had 2 recovery programs or rom managers on the phone 1 is cwm and other is teamwin recovery.also rom manager asks me to update or upgrade cwm but it does't recognise the device cos it is i9505 with i9500 rom and rom manager couldn't identify the device as it should be.so cwm update doesn't work.also i couldn't get to the user interface of cwm which is already on the device no matter what i do.also i know old version of cwm will not make it happen for what i need to do if i was able to get in the user interface as well.i think teamwin is blocking cwm.

so on rom manager i decided to use the team win cos there is no other option for me there which puts the phone after a restart to recovery mod,the user interface works ok there but teamwin also FAILED TO WRITE THE ROM(i think it is an old version too)i couldn't say the exact version of cwm cos the device is not with me and i forget the version but team win i asked to my friend just yet and he said TWRP 2.6.00 is on it.

3)CWM i can't even get to user interface,i really don't know how to with team win there.So yeah i couldn't even give a try.

4)I am stuck.and i don't know what to do.

general user profile about me: i have a general understanding of computers,but i haven't written any rom to galaxy s4 before yet i found myself in a situation i can't handle.someone screwed up an i9505 with a i9500 rom.

ANY HELP FROM ANYONE will be very appriciated.
