how to unroot a mediatek mtk android phone

It does feel good to see an Over The Air (OTA) update from your Original Equipment Manufacturer (OEM), especially when its a leap from one major version of Android to another. In a haste to update, some device users end up encountering errors or even bricking their phones while trying to install OTA updates on rooted devices; causing the phones in question to always boot straight into recovery mode. In such a situation, a factory reset doesn’t help in any way. We did provide a fix for this at https://forum.hovatek.com/thread-5517.html but today’s guide is focused on prevention.

Why do I need to unroot before I can install an OTA update?

OTA updates are signed. This means the Android system checks the integrity of core partitions before proceeding with installation of the OTA zip file. What this means is that if you have somehow altered these core partitions, you will likely encounter an error or end up with a bricked Android phone.

What exactly am I trying to achieve by unrooting?

You are simply trying to return your boot, recovery and system partitions to their original states so they can pass the System test (Root Integrity check).



How do I perform a Root Integrity check?

Why isn’t the unroot option in my SuperSU or Kinguser the best option for me?

We’ve had a number of bricked phones due to opting for this method of unrooting. Your /system partition has already been modified / patched so you’re still exposed to the possibility of an incompatibility with the OTA zip file since the Super User unroot option does not completely cover its trail.

How do I unroot an MTK phone before flashing an OTA update?

You will be reverting the boot, recovery and system partitions because they are core and are commonly altered in order to root or after rooting. To unroot your MTK Android phone ahead of an OTA update:

Will I lose my data after unrooting using this method?

If you flash only recovery, boot and system (Android) then your data will not be affected. If -on the other hand- you flash the entire firmware then you will lose your data.

  1. Good day Sir.

    Been scouring the net for a fix to a dilemma I have with my Infinix Note 3 X601and stumbled on your website with its boatload of help, guides and tips. I can say I’ve been truly enriched.

    My problem is this. My phone is rooted and runs Nougat XOS v 139. I would like to upgrade it to the v152 update recently released. Tried uprooting via the SuperSu app but that didn’t work of course..

    Just read your tutorial on unrooting MTK devices through flashing system, boot and recovery files. I could do that, sure, but I’ll like to know if either of these two can also work for me:

    1. Flashing the update manually via SP Flash Tool/and then immediately rerooting through custom recovery before booting into Android.

    2. Using the Flashfire app to install the update from my phone.

    I’ll be grateful if you can give me guidance on this issue.

    Thank You,

  2. Sir pls where did u post the link so I can download it.

  3. OK boss any info for me on flashfire usage cause I saw that on ur bbm channel
