What can be done with the z3x box


Write, restore, update firmware and software

The most common uses for these functions are either upgrades to new firmware versions or downgrades to older ones. Sometimes it is used to change or add languages. In 90% of the cases, most of the restart, freeze and no-boot errors are solved after a software update of this type.

Locked Phones.

The most common reason that phones are flashed, is that they are locked to a particular cellular network. You may need to flash your phone in order to use it on a different network, which is known as a partial flash.

Full Flash

A full flash refers to actually changing the operating system on your phone. If you undertake this type of flash, all of the information on your phone may be removed. A full flash could just mean upgrading or downgrading to a different version of the operating system on your phone, or changing to an entirely new mobile operating system.

Note! Flashing your phone may void your phone's warranty and it may render your phone depending on the security measures in place on your phone.

Read/Write EFS

The EFS is a special partition dedicated for your phone's info like radio signal info, IMEI, serial number and lots of files revolving around your SIM card and Wifi, and Bluetooth (this includes your MAC address for all the radios of your phone) in an encrypted format at the file system level stores. Imagine the EFS as a big folder containing all of the important stuff that makes the "phone" part of your phone. It is very necessary to backup EFS before flashing ROMs.

Read/Write QCN

Qcn means Qualcomm calibration network file. Basically, QCN file built-in in all Samsung Galaxy mobile phone and latest android mobile phone. QCN is the main, sensitive, file of the network hidden in the deepest core of mobile phone internal memory file system (in efs folder, where all information of IMEI and baseband are saved).

Direct READ codes

This function can successfully read the code stored in the phone. Code reading is considered to be a safer method of unlocking which has at least 2 positive moments.
First of all, nothing except reading operations takes place during the unlock code calculation process. If you're not writing anything into the phone's memory, you don't risk to burn incorrect data into the critical parts of the memory that can cause phone's malfunctions. It is especially critical if it's hard to find firmware or a flasher for a certain phone model in order to fix it after the unsuccessful attempt of direct unlocking.
Second, writing into the flash memory with direct unlock will void the phone's warranty. Phone servicing software during the unlocking process modifies certain protected parts of the memory that is typically unreachable for the user. Usually techs from authorized servicing centers can tell if the phone was flashed with third-party tools.

Reboot download/recovery

Backup & Restore
We are trying to create backups automatically before each critical part of the process; this is a functionality that provides extra safety. We can not save all the individual calibration and security settings before each process because it will be quite laborious, but we will give you the opportunity to do it yourself.


This is often the first step we need to do when we have a smartphone locked to a specific carrier (Telecommunications Service Provider). In CDMA phones, it is often that carriers will lock the phone to their specific programming code. This is normally because the carrier subsidy the phone and sells it at a very cheap price (sometimes free phone) with 12-24 months contract. The Service Programming Code (SPC) or Master Subsidy Lock (MSL) usually consist of a 6 digit code (GSM) or 16 digit code (Blackberry).

FRP remove

Remove Google account from the phone

Read/Write CERT

Reading and writing digitally signed certificates became necessary because in some Samsung models the serial number (IMEI) was stored and protected in this manner. Thus the manufacturer aimed to prevent one from manipulating the originally stored serial number without authorization. Sometimes this part gets damaged or overwritten by an improper tool. If this occurs, having a backup of that part can be very useful, enabling the ability to make a hassle-free restoration.
In some cases, a previously saved content can also be restored to other devices by repairing them in the same way. It is important to note that in the later situation this means that this serial number is cloned as well.


Unlock (Root)

Direct unlock
As we mentioned before, there are two ways to remove the network locks: to direct unlock and to read out the unlock code. This feature is designed to avoid having to do any extra steps after the successful completion of the process. The device can be used immediately with the SIM card of any provider.

Read/Write SEC

SEC - contains fuse settings, mainly for secure boot (signing bootloaders for chain of trust) and oem setting

Unlock TMB (via server) for latest FW (Bit2) and KNOX1

unlock T-Mobile (TMB) devices

DIRECT Unlock SPR via Server(PERMANENT, any KNOX, without downgrade and wipe)
