NOTE: You do this at your own risk and I will not be held responsible if something goes wrong
This method uses an Android phone, mainly because it is easy to see what is happening.
The root is done by patching a stock “boot.img” with Magisk Manager and using SP Flash Tool to flash it onto the LEM8.
What you need is:
SP Flash Tool
Stock ROM, the same version as is on the watch, from:http:///thread/2937/lemfo-lem8-z29-m6739-16gb
Note: it refers to Update 1.2 but it really should be Update 1.3. My LEM8 was version 1.2 and I previously updated it to version 1.3.
Download and unzip the stock ROM file
This download includes SP Flash Tool and also can be used to reflash the stock ROM if something goes wrong.
Magisk Manager apk – you need to download it from the Internet as it is not on Play Store.
Version 7.0.0 is the latest.
Stage 1 – Patching the boot.img
a) Copy Magisk Manager apk to your Android phone and install it
b) Make sure that you are connected to the Internet
c) Unzip your Stock ROM download
d) Find and copy the boot.img from your stock ROM to the root of internal memory or SD card
e) Run Magisk Manager and wait until buffering stops
f) Tap on Install for “Magisk is not installed”
g) Tap on Install under the Install Magisk pop up
h) Select “Patch Boot Image File”
i) Navigate to where you put the boot.img and select it
j) The boot.img will be patched and stored in the internal memory under “Download” with the name “patched_boot.img”
k) Unfortunately, I could not see this file from my PC so I had to use a file manager apk to copy into the root of either the SD card or internal memory so that I could copy it to my PC.
l) Store this file in the same folder where you unzipped your download
Stage 2 – Loading the “patched_boot.img” onto the watch
a) From your unzipped download, find and run SP Flash Tool
b) Choose the scatter file of the stock ROM that you downloaded
c) Find the “boot” sector and click on the “Location” in the right-hand column
d) Navigate to where you stored the “patched_boot.img” and load it in.
e) TURN OFF your watch, make sure that the charging plate is NOT connected to the PC.
f) Mount your watch on the charging plate
g) In the SP Flash Tool click on the box in the header line to unselect everything (no ticks)
h) Click the box for “boot”, a tick will appear – only “boot” should have a tick next to it
i) Click on “Download”
j) Insert your charging plate USB cable into your PC
k) The “patched_boot.img” will be downloaded and flashed on your watch. You can reverse this by using the stock “boot.img”
l) You should not lose any data or apps if you only flash the boot
m) Start up your watch, download “Rootchecker” by joeykrim from the Play Store
n) Confirm ROOT.
o) Good Luck!!
