<OSM> Check MD5.. Do not unplug the cable..
<OSM> Please wait..
<OSM> I747UCALG1_I747ATTALG1_I747UCALG1_HOME.tar.md5 is valid.
<OSM> Checking MD5 finished Sucessfully..
<OSM> Leave CS..

and on my phone is says SV REV Check Fail : Fused 2 > Binary 0
i was trying to find stuff out online and they said something about a bootloader and i have no clue what that means. also, cyanogenmod is no longer even going to the home screen so my phone is not functioning at all. and since it isnt loading, my computer isnt detecting a device so i cant add any files to my phone.
can someone please help me? using english please, not computer hacker language. im not that advanced in this kind of stuff.
if you still can go into downloadmode, you can unroot your device and put it back to stock with Kies 3.
Download Kies 3 from samsung web site and download Samsung USB Drivers too
Unplug your phone from the PC
After on Kies 3 click on tools>emergency firmware update and inisialitazion.
Now they will ask for your phone model so if you are on at&t its : SGH-I747 (Rogers bell .. tis : SGH-I747M
After, Kies 3 will ask you your S/N (this can be found under your battery the sticker) so remove your battery and write it down
Know if it work they gonna tell you to put your phone into download mode
To go into download mode hold : Volume Down + Home Button + Power button
After on your phone you should see a Yellow triangle with some warning (jUst ignore that and press the volume up button)
And Kies 3 will automaticly unroot your phone, flash the new 4.3 update and flash the new bootloader too.
!!!***WATCH OUT! DO A BACK UP OF YOUR INTERNAL MEMORY BECAUSE YOU ARE GOING TO LOSE EVERYTHING***!!!
And after you just have to wait.... Kies 3 will download automaticly 4.3 Firmware and flash it on your phone.
Make shure that your battery is charged at least at 30% before doing that.
And after enjoy your phone unrooted and on stock rom and after you will be still able to update your phone for futurer update availble.
Tell me if it worked for you after!
