1. Recognize Phone is a MTK Device or Not

This Post is Only For MTK Smartphone, and it will not useful for other Android Smartphones.So Lets start with Recognizing That Your Android Smartphone is a MTK Device or Not.If Yes then You are at right place and here i will try to explain all possible methods and steps that can help you to Unbrick  your bricked Smartphone.

What Is MTK ?

MTK stands for MediaTek, and MediaTek is a well-known chip manufacturing company(Taiwan). MTK phones or MTK Devices are Those Phones and Devices which use MTK chips.

What is Kernel?

The kernel is what allows your phones software to interact with the hardware. It contains all the necessary info for boot, and also your phones drivers. There’s a line in the kernel called “bootclasspath”, and if this isn’t what it should be for your device, you will get a hard brick, as this line tells your phone how to boot.

How to Know that Your Android Smartphone is a MTK Device or Not?

Now if you really want to know that whether your android devices are MTK devices or not, then there are two very common Methods:-
  • With a tinny Android App:-
    1. Open Google Play Store.
    2. Search “CPU-Z” in it and Download it.
    3. When the Application is Installed, Open the app and you will see all your phones and hardware components models.
    4. On the Main Screen you will see about 5 menu buttons at the top Click on SOC (System on Chips)
    5. On the SOC menu, you will see the chip and model of your device boldly written at the top portion of your screen. 

CPU-Z – Android Apps on Google Play

2. Some Basic Information about Android Smartphone Brick

There are two types of Smartphone Brick First one is Soft Brick and Second One Is Hard Brick.Both are explained Below one by one.


What is soft brick?

A Soft Brick or a Software Brick, is usually just when you’re phone is stuck in a bootloop, and as the name implies, is caused by a software error, usually the lack of a system to boot from or some other minor software bug that glitching boot. They are easily fixable by flashing the stock rom through recovery or with SP Flash Toot.If your Android device turns to a soft-brick, it may:

  • Keeps Rebooting;
  • Boots Straight Into Recovery;
  • Boots Straight Into its Bootloader;
  • Freeze at the start up screen or boot Animation;


What is Hard brick?

A Hard Brick or a Hardware Brick is where you’re device won’t boot at all, It Means No Recovery or Bootloader, No Startup, No Vibration, No Battery Indication and the Notification led will also not work in it.These are usually caused by people flashing ROMs or kernels not meant for their device. Flashing a ROM not meant for your device, can throw your system through a loop, because it also flashes the kernel. You have to either repair it yourself, using a JTAG or send it into a JTAG service to have it fixed. 
In Short:-
Soft Brick = Recoverable without professional repair.
Hard Brick = Not recoverable, Almost Dead.

      3.A) Basic Procedure to Use JTAG to Unbrick Android Smartphone (Only For Hard Brick)

      JTAG :-
      Now At the Last of this Article Let me Explain You about JTAG,
      From Wikipedia:-

      The Joint Test Action Group (JTAG) is an electronics industry association formed in 1985 for developing a method of verifying designs and testing printed circuit boards after manufacture. In 1990 the Institute of Electrical and Electronics Engineers codified the results of the effort in IEEE Standard 1149.1-1990, entitled Standard Test Access Port and Boundary-Scan Architecture.
      JTAG implements standards for on-chip instrumentation in electronic design automation (EDA) as a complementary tool to digital simulation. It specifies the use of a dedicated debug port implementing a serial communications interface for low-overhead access without requiring direct external access to the system address and data buses. The interface connects to an on-chip test access port (TAP) that implements a stateful protocol to access a set of test registers that present chip logic levels and device capabilities of various parts.

      • JTAG is a Protocol ! Simply in other Protocols such as USB is protocol UART is protocol for transferring DATA or communicating with devices .
      • JTAG Directly communicate with the CPU and with the help of CPU’s JTAG Protocol you can access CPU’s peripherals and memory/NAND/eMMC one of this peripherals .
      • In order to relate directly answer to your question for the reviving part . Even Though your device is not able to boot-up from the internal memory/NAND/eMMC JTAG access still available through JTAG Protocol .
      • Accessing JTAG and re-writing Boot partitions to your device internal Memory/NAND/eMMC will revive your phone , phone will be able to boot-up and will be revived .

      JTAG pins exist either under your device’s battery or near its SIM / MicroSD card holder. The pins are hidden. You may have to dismantle your phone’s back cover. The JTAG pins are usually six gold pins clustered close to each other,You use a special hardware JTAG box which comes with a vast array of cables (different cables for different types of devices), plus specialized software specifically made for your device model. (There exist generic catch-all JTAG boxes that can be loaded with specific microcode instructions for your particular manufactured board. The tricky part is getting the exact microcode for your device’s circuit board. If you use the wrong microcode, it can cause permanent damage.)The microcode instructions are emitted by the JTAG box attached to the cable, clipped in position on top of the JTAG pins. The box sends a signal to your device to revive it. Now an appropriate firmware image can be flashed to your device.You have to find which pins are used for ground (GND), transmit (TX), receive (RX) and power (PWR). The power is the important one. if the battery is dead, power can still be fed into your device.You can buy JTAG boxes online, but they tend to cost a couple hundred US dollars or so. It’s because of differing manufacturers with different types of cables, and different arrangements of on-device JTAG pins.With JTAG You can Unbrick Any Android Smartphone and it is also having very good success rate.

      3.B) Go contact the manufacturer for service

      If all method mentioned above fails, take it to the service center to unbrick your Android device. They can simply flash the stock things back and hand it over to you even without a root checking. Please make sure you can keep your data on the device.
