UFI Box vs Easy JTAG vs F64 Box – Which Programming Box Is Best?

In mobile phone repair, choosing the right programming box is very important. A good box can save dead phones. A wrong box can waste time and money.

Today, many technicians are confused between three popular tools:

UFI Box
Easy JTAG Box
F64 (Flash 64) Box

Each box is good in its own way. This article explains the difference in very simple words, so you can easily decide which one is best for your work.

What Is a Programming Box?

A programming box is a hardware tool used to work directly with phone storage chips. These chips can be eMMC or UFS.

These boxes help in:

eMMC and UFS repair
Dead phone recovery
FRP unlock
Storage health repair
Low-level flashing

Normal flashing tools cannot do this deep work. Programming boxes are used when phones are seriously damaged.

UFI Box – The Easy and Flexible Tool

The UFI Box is one of the most popular tools in the market. Many technicians start their repair journey with UFI.

The biggest advantage of UFI is that it is easy to use. The software is simple, and beginners can understand it quickly.

UFI supports both eMMC and UFS chips. For this, it uses different adapters. It also supports BGA adapters and ISP method, which means you can work without removing the chip in some cases.

One very strong point of UFI is Samsung FRP unlock, especially on newer Samsung phones with UFS storage. Many other tools fail here, but UFI performs well.

UFI Box is a good choice if you do:

Samsung FRP work
General eMMC repair
Normal UFS jobs

Easy JTAG – The Old but Trusted King

Easy JTAG is often called the king of programming boxes. Many technicians trust it because of its stability and accuracy.

Easy JTAG supports UFS up to version 3.1, which is better than basic UFI support. It is very good at detecting damaged chips.

One special feature of Easy JTAG is its one-click identification. If a chip is bad, Easy JTAG tells you immediately. It does not waste time trying again and again.

This saves a lot of time in busy repair shops.

Because of its long history, Easy JTAG is still the industry standard for:

Deep IC programming
Professional-level repair
Accurate chip diagnosis

If you value reliability more than speed, Easy JTAG is a solid choice.

F64 Box – The Fast and Modern Tool

The F64 Box (Flash 64) is the newest tool among the three. It is becoming very popular because of its speed and modern features.

One thing that makes F64 special is its built-in digital display. This screen shows real-time voltage values like VCC and VCCQ. It also has RGB lights to show working status.

This helps technicians see what is happening during repair, which increases safety.

F64 Box supports the latest UFS 4.1 chips, which is higher than both UFI and Easy JTAG. This makes it very useful for new flagship phones.

Another big advantage is speed.
F64 can reach around 60 MB/s, which is much faster than Easy JTAG and UFI.

If you work on new phones and want fast results, F64 Box is a strong option.

Speed Comparison (Simple)

Let us understand speed in easy words.

UFI Box: Around 20 MB/s
Easy JTAG: Around 30 MB/s
F64 Box: Around 60 MB/s

This means F64 is almost double the speed of Easy JTAG and three times faster than UFI.
