I9505EfsRepairZ3x: How to Fix Your Samsung Galaxy S4 IMEI and MSL Errors

If you have a Samsung Galaxy S4 with model number I9505, you may have encountered some problems with your IMEI (International Mobile Equipment Identity) and MSL (Master Subsidy Lock) codes. These codes are essential for identifying your phone and unlocking its network capabilities. However, sometimes they can get corrupted or erased due to various reasons, such as flashing custom ROMs, rooting, or updating firmware. When this happens, you may experience issues like no signal, invalid SIM card, or network lock.

Fortunately, there is a way to fix these errors and restore your phone's functionality using a tool called Z3x. Z3x is a professional software that can repair IMEI and MSL codes for various Samsung models, including the Galaxy S4 I9505. In this article, we will show you how to use Z3x to fix your I9505 EFS (Encrypted File System) and restore your IMEI and MSL codes.

What You Need

A Samsung Galaxy S4 I9505 with root access. You can root your phone using [this guide].

A USB cable and a micro UART cable (C3300).

A computer with Z3x software installed. You can download Z3x from [here].

A backup of your EFS and QCN files. You can make a backup using Z3x or any other tool.

How to Repair I9505 EFS Using Z3x

Launch Z3x on your computer and select I9505 as the model.

Connect your phone to the computer using the USB cable and enable USB debugging on your phone. To do this, go to Settings > More > About device > Tap on Build number 7 times > Go back to Settings > More > Developer options > Enable USB debugging.

On Z3x, click on Repair and enter the IMEI number you want to restore. You can find your original IMEI number on the back of your phone or on the box.

Click on Write EFS/NVM and wait for the process to complete. This will write the EFS data to your phone.

When prompted, switch to the micro UART cable and connect it to your phone. This will bypass the MSL security and allow Z3x to repair your IMEI.

Click on Repair IMEI and wait for the process to complete. This will write the IMEI data to your phone.

Reboot your phone and check if your IMEI and MSL codes are restored. You can check them by dialing *#06# for IMEI and *#0011# for MSL.

Troubleshooting Tips

If you encounter any errors or problems while using Z3x, here are some tips that may help you:

Make sure you have the latest version of Z3x software and drivers installed on your computer.

Make sure you have root access on your phone and USB debugging enabled.

Make sure you have a good quality USB cable and micro UART cable that are compatible with your phone.

Make sure you have a stable internet connection and disable any antivirus or firewall software that may interfere with Z3x.

If you get an error message like "Bypass MSL... error" or "Repairing IMEI... error", try rebooting your phone into recovery mode and select CP logging. This may help Z3x to access your phone's modem.

If you get an error message like "Writing data to phone... error" or "Reading phone info... error", try downgrading your phone's firmware to Android 4.4.2 KitKat or lower. This may help Z3x to write or read data from your phone's EFS.
