Samsung Daseul

What is Samsung Daseul and how does it work

Samsung Daseul is a software tool that allows authorized service centers to repair or rewrite the IMEI (International Mobile Equipment Identity) of Samsung devices. IMEI is a unique 15-digit number that identifies each mobile device and can be used to block stolen or lost phones from accessing the network. Sometimes, the IMEI can get corrupted or erased due to software issues, flashing, rooting, or unlocking. In such cases, Samsung Daseul can restore the original IMEI or assign a new one from Samsung's database.

Samsung Daseul requires access to GSPN (Global Service Partner Network), which is Samsung's online portal for service manuals, firmware updates, spare parts ordering, and IMEI writing. Only authorized service centers with valid credentials can log in to GSPN and use Daseul. Daseul also requires a special cable called UART (Universal Asynchronous Receiver-Transmitter) that connects the Samsung device to the computer running Daseul. The UART cable enables communication between the device and Daseul via AT commands.

Once connected, Daseul can read the current IMEI of the device and check its status on Samsung's server. If the IMEI is valid and not blacklisted, Daseul can repair it by writing it back to the device's EFS (Encrypting File System) partition. If the IMEI is invalid or blacklisted, Daseul can rewrite it by requesting a new IMEI from Samsung's server and writing it to the device's EFS partition. Daseul also generates a log file and a .cert file for each IMEI operation. The log file contains information about the device model, serial number, old IMEI, new IMEI, date and time of operation, and GSPN user ID. The .cert file contains cryptographic data that verifies the authenticity of the new IMEI.

Samsung Daseul is a powerful and useful tool for legitimate service centers that need to fix IMEI issues on Samsung devices. However, it is also a potential target for hackers and fraudsters who want to unlock or resell stolen or blacklisted phones. Therefore, Samsung has implemented strict security policies and measures to prevent unauthorized access and misuse of Daseul. For example, Daseul requires internet connection and GSPN login for each operation, limits the number of IMEI requests per day, encrypts the communication between Daseul and Samsung's server, and tracks the history of each operation.

How to use Samsung Daseul to repair or rewrite IMEI

To use Samsung Daseul to repair or rewrite IMEI, you need to follow these steps:

Download and install Daseul Library Installer from GSPN. This will install the necessary drivers and libraries for Daseul to work.

Connect your Samsung device to your computer via a UART cable. Make sure the device is in download mode or normal mode depending on the model.

Launch Daseul from GSPN and log in with your GSPN credentials. You will see the main interface of Daseul with four tabs: Read, Repair, Rewrite, and Log.

Select the Read tab and click on Read IMEI. Daseul will read the current IMEI of the device and display it on the screen. You can also check the status of the IMEI on Samsung's server by clicking on Check IMEI.

If the IMEI is valid and not blacklisted, you can proceed to repair it by selecting the Repair tab and clicking on Repair IMEI. Daseul will write the same IMEI back to the device's EFS partition and show a success message.

If the IMEI is invalid or blacklisted, you can proceed to rewrite it by selecting the Rewrite tab and clicking on Rewrite IMEI. Daseul will request a new IMEI from Samsung's server and write it to the device's EFS partition and show a success message.

After each operation, you can check the log file and the .cert file generated by Daseul by selecting the Log tab. The log file contains information about the operation and the .cert file contains cryptographic data that verifies the new IMEI.

What are the advantages and disadvantages of Samsung Daseul

Samsung Daseul has some advantages and disadvantages as follows:

Advantages:

It can fix IMEI issues on Samsung devices that are caused by software errors, flashing, rooting, or unlocking.

It can restore the original IMEI or assign a new one from Samsung's database that is compatible with the device model and region.

It can prevent stolen or lost phones from accessing the network by blacklisting their IMEI.

It can generate log files and .cert files for each operation that can be used for troubleshooting or verification purposes.

Disadvantages:

It requires access to GSPN, which is only available for authorized service centers with valid credentials.

It requires a UART cable, which is not a common accessory for most users.

It requires internet connection and GSPN login for each operation, which can be slow or unreliable depending on the network quality.

It limits the number of IMEI requests per day, which can be insufficient for some service centers with high demand.

It is vulnerable to hacking or fraud attempts by unauthorized users who want to unlock or resell stolen or blacklisted phones. 061ffe29dd
