Samsung Exynos devices: Read codes for network unlock - ChimeraTool help

In this guide we will go through the steps of reading the network unlock code and other codes from a Samsung Exynos device, allowing you to remove network lock with only a few simple steps in Chimera Tool - which can read them from your device.
 

STEPS:

First, put the device in EUB mode by shorting the test point pins on the device. If you don't know how to put your phone into EUB mode, visit our Test Point collection here: https://chimeratool.com.cn/test-points. Once done, Chimera will recognize the device and the next steps will run in Exynos mode.

Click on the Network Factory Reset tab, then on Read Codes. Select the latest method and wait until Chimera reads the codes.

You will get various codes: the Master lock code and the Network unlock code. The Master lock code is needed after the 3 unsuccessful unlock attempts when your device asks for Network PUK or Master unlock code. The Network unlock code is needed when your device asks for Network PIN code or Network unlock code.

Select the Network lock code option and wait for results to appear. The next time you insert a SIM card of another carrier, you will be requested to enter this code to remove network lock. This will be requested only once, when device turns on the first time with a new SIM card from a different carrier.
