This is a guide of MTK Phones flashing. It is not that hard like others saying. It is easy and what you need more is care. MTK phones won’t be bricked when flashing just if you are careful.
Card flash. Easier than cable flash (If the recovery is in). -MTK Phones Flashing
Prepare: 1. SD card. 2. Battery power over 70%.
Send the zip file (rom) to your SD card, remember do not unzip the zip, and it is better if it is a blanket SD card.
Power off the phone and insert the SD card. Normally you need to press volume- (may be +, depends on your device) and power on button for over 8 seconds to go into the recovery model (Some device will be dark screen, just click the menu button to enter).
You can see some options below, like apply upgrade from SD card/ choose .zip from SD card/ wipe the caches/ wipe the data/ reboot your system. Normally volume -/+ to move, power button to confirm. What we need is to do a double wipe (wipe data & wipe caches) before your flashing, and then choose .zip from SD card and confirm.
If the rom is right, your device will continue and finish upgrading itself. Or you will get a notice like “installing aborted”, which means rom is wrong or the zip is broken. After you reboot your phone, you will get the new system.
*Card flash is easier than cable flash, just step by step, you can upgrade your phone easily. Some devices will not recognize SD card even if you insert it into your phone. You need to do a double wipe first and then start up the phone and send the zip file to your phone storage, and power off to go into the recovery. —MTK Phones Flashing.
