[General Topics] MaimeiteROM:
For those who are looking for the firmware of Maimeite M3 Pro, I have attached here the zip file. Don't worry I didn't put a password so you're free to extract it. You may need to use SP Flash Tool to flash the firmware. The Maimeite M3 Pro is a chinese clone of the Poco M3 Pro. It has a 512MB of RAM, 1.3GB of internal storage, 3MP Rear cam and i think 1MP of front cam. I know you would say that these are terrible specs and really outdated OS but I've got to appreciate this thing as it was a gift to me by my grandma.

Let me tell you how I got this firmware....

The stock firmware of this phone comes preinstalled with adwares as what you might expect from a cheap clone china phone. It really sucks whenever I connect it to the internet, the ads are randomly popping out on the screen, it downloads malicious apps by itself. So I decided to root it to uninstall the system apps that are adwares which are causing the issue. I was able to gain root access and uninstalled the suspicious system apps. Yes it worked, it fixed the issue and I was no longer receiving ads/malwares but while navigating the kingoroot uninstaller application, I accidentally uninstalled the telephony provider which made the phone unusable because of the "the process has stopped" window that kept appearing on the screen....

So yeah maybe some of you may just throw it in trash heheh but I can't do it as this was a gift to me by my loving grandma. After all, it's not really a bad phone for basic uses like messaging, facebook, internet browsing, echolink, zello). I was left with no other options but to reflash the stock firmware. Unfortunately, I couldn't find its stock firmware on google, well there is one I found from KangSuper but the zip file is password protected and you have to pay for it to obtain the password and be able to extract it. There are other firmwares I found on google not specifically made for M3 pro but its stated device model is x6_v5_x50, which is the same as with the Maimeite M3 Pro. Looking up the x6_v5_x50 on google revealed that there are lot of chinese clone models who share the same motherboard, chipset and their firmwares are all based on Android kitkat 4.4.2. My plan was to search and download any firmware for x6_v5_x50 that is free and copy its system.img to replace the same one on the original firmware of Maimeite M3 Pro. It worked and the phone became usable again. The system.img that I flashed on the phone was from the firmware of Note30 plus which is also a chinese clone. But again, it came preinstalled with adwares and getting root access was unsuccessful.

Since this ported firmware that I made is unrootable, I decided to unpack the system.img and deleted the apk and odex files of the suspicious apps. I've also edited the build.prop and changed the value of qemu.hw.mainkeys to 1 to disable softkeys because these are enabled by default and the Maimeite M3 pro uses capacitive buttons instead. Then I repacked the system.img and flashed it on the phone...Problem Solved!

Now the phone works wonderfully and adware free. Maybe there are folks out there who'll need this firmware so I decided to share it here....Make sure that if you use the SP Flash Tool, all the boxes are ticked, if not, you may need to point the location of the file. I assume that you already know how to use the SP Flash Tool. There are many tutorials out there if this is the first time you heard the tool.
