- Before you claim the eMMC is faulty, make sure the battery isn't dead or the Android phone's battery didn't drained after flashing.
What is eMMC?
The eMMC (Embedded Multi-Media Controller) is an IC that functions as a data carrier (internal memory) and controller.
partitions like Bootloader, Recovery, System OS, Storage Media (Internal Memory), EFS and various other partitions are stored in this IC.
Structurally, eMMC consists of two parts, namely a nand Flash IC and a controller that controls the nand Flash IC.
The Nand flash and the controller are one unit, so if the Nandi flash is damaged, the controller must also be replaced. Simply put, replacing the eMMC means replacing the nand Flash IC and the controller (processor).

What are the characteristics of a weak or damaged eMMC?
Early signs of a weak eMMC include:
- Android Phone restarts itself frequently;
- Android Phone often overheats or freezes even with normal use;
- Turns itself off unexpectedly and has to be turned on again, sometimes wants to start, sometimes doesn't, unless charger is connected;
- Often "The process android.process.acore stopped unexpectedly" or "Unfortunately, the application has stopped";
- Suddenly the internal memory is not read (Unmount SD);
- It often hangs/freezes even though it's just updated again and there aren't many apps installed; and
- Various other characters.
If the eMMC functions are damaged or weak, please do the following:
- Always fails during flashing;
- Flashing works for a while and fails;
- Flashing, wiping or reset succeeded, but data is not lost yet (returns to normal);
- Flashing succeeded, but the smartphone still does not turn on; and
- Several other options.

So, if you experience any of the above, you should be alert. If possible, do not flash again, fearing that the flashing process will not be completed, but the smartphone will die first.
If the eMMC is weak or starts to fail, everything you modify or change will go back to how it was (read only). So the flashing is complete and successful, but your mobile still boots up and can't boot to the home screen because your eMMC device can no longer be written (edited/wiped).
This happened to my colleague's Mi 4 smartphone.
Fastboot mode can still be entered, flashing is also possible. But on restart, the mobile turns on until the MI logo appears, then vibrates and turns off again, and continues.
When the charger is plugged in there is no telling how the LED lights until it finally turns off completely and won't start, try until the deep flash cable doesn't work.
Meanwhile, I can still type fastboot on my Redmi 2 Prime if it's only with the Mi logo on it. I tried flashing again but it still fails due to a corrupted partition or installation error.
Then I tried to install TWRP and it worked, but it always failed during the wipe and recovery process. When it is connected to the computer, it is detected as unknown devices.
How to check the status of your eMMC phone
Before going through the above, you should first check the current status of your eMMC phone.
Use an app that you can download from the Google Play Store » eMMC Brickbug Check, but as long as your smartphone is rooted.
Check eMMC health by selecting the Check Memory menu.
Wait for the process to finish and see the results as follows...
If the test results are Passed, it means your eMMC is still healthy.
Is the eMMC replaceable?
If you start to suspect that the eMMC is weak, do the following:
- If the device is still able to enter TWRP, try a wipe and reset;
- If you managed to flash either with fast boot or EDL mode and still does not start by selecting "flash_all/clean_all", do not flash again, try to change the battery (you can borrow from a friend);
- If you have replaced the battery and it still does not start, the eMMC may be damaged.
What is the solution?
Yes, take it to a serviceman who really understands eMMC replacement. Don't let the damage spread to other devices like my Asus Zenfone 5 case.
