[Galaxy S 4 Q&A, Help & Troubleshooting] Boniakowski:
Hi, I'm new to this subject and the truth of z3x 've started on the wrong foot .

buy my z3x to begin working with i9500 which turn on and I went out the legend only emergency calls, my problem was from the beginning , I have installed the drivers appear correctly on windows 7 x64, when I start the tool samsung 17 I bottom of the window says , cars found (OK ) and then tells me NOT FOUND BOX but starts correctly, however, if I open the shell on the i9500 model only reached reading card found and then a number XX -XX # # # # # # -XX or something like that does not matter because I assume is the activation of the box , well I press :

1 - I configured the phone in debug and everything.

I tried using the two - S7070 UART cable connect the phone to the box and I never EVER answer by S7070 UART uart cable or any other cable, 3300k clarify that I have not since I never came in my kit installation .

3 - Connect the original cable that came with my phone direct from my notebook and lo and behold, there I recognized the phone .

4 - unlock i tried to make no changes .

5 - try to restore the network, but no change either .

the phone had version 4.3 and up and did a downgrade to version 4.2.2 with the risks that could run . to the top after making flash 4.2.2 reboot when the phone was hung on the samsung logo , but I did a cache wipe and then a wipe and factory reset the phone when everything worked correctly.

6 - I connected the phone again and I 'll take my imei NULL to try to restore a previous efs that I had saved , well if it was not the version 4.2.2 or version 4.3, do not remember.

7 - with the phone connected by direct mini usb from my notebook always pressed write efs and instead of looking at my previously saved with root explorer folder, what I did now was to search the backup files that had generated me the same z3x not know why I did this, but I selected the one that had the oldest date before I modify anything, so thought I would take the information from my imei from there, but I flatly wrong.

when the phone restart was permanently a bootloop on the logo samsung and never could get him out of there, I intnté do wipe again and nothing happened, I can enter download leisurely mode and also in cw vol up + menu + power on the notebook I listed as usb modem phone or something, but as I fail to operate any single uart cable usb mini me works, read the info when I search the phone always says PHONE NOT FOUND, not let me take any further action.

8 - now when I do a wipe I get the legend on the screen that says ...

e: failed to mount / efs (invalid argument) and stuck at the samsung logo.

no more to do or how to correct my problems to revive this phone mia agony.

could someone give me a very detailed step tutorial that can make step. do not forget that many newly started on this topic and please talk with us tomense unclear terms and cordial to answer very clearly some things that are very easy to units for us but maybe very difficult time.

please help with my UART since my box is useless without this work or am I wrong? :(

thank you very much.

There is no way of putting on the version : - SEK - I9500XXUBMG1 20130702160308.zip - I9500XXUBMG1_I9500OXEBME1_I9500XXUBMG1_HOME.tar.md5

and will again lower the version 4.3 to 4.2.2 to see if the version mentioned so loaded up with this file ( Clar0 ) I9500UBUAMDK_I9500UWAAMDK_CTI.zip - I9500UBUAMDK_I9500UWAAMDK_I9500UBUAMDK_HOME.tar.md5

but it says the same thing in red UNSUPPORTED VERSION . when I try to charge you the version of the post : w*w.clangsm.com/forum/index.php?showtopic=324565

not to do now , someone hand me that ? if you do a wipe after the newly installed version of course I still dicendo E: Failed To Mount / efs (invalid Argument ) Locked In And Meet The Samsung Logo .

I forgot to clarify that after the error obviously odin and text on cell unsuppoerted version , if I disconnect and try to turn me obviously goes the legend on screen with a warning symbol (Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again)
