After bricking several devices I wanna Share you all about the precautions needed to be taken while customising MiBand4

Precautions regarding resource customising;
1. Never resize the xx.png containing in the resource file.

2. Never edit the header.json file in the resource file.(will cause brick)
3. Always save you png in 8-bit
Open your new .png in photoshop go to save as- save for web- png 8 and then save your Image

Precautions regarding Firmware:
*No advices for it because firmware is uneditable.
But still you all need to take some precautions


1. Be aware of flashing beta firmwares(note: If you are flashing resources flash it at your own risk no one will be responsible for it try flashing it by notify and fitness.)

Precautions regarding Font:
*Generally fonts do not brick your band but still use tested fonts and be aware too.


Resources/Firmware and conformity:
Please be very sure of flashing correct firmware and corresponding resources to it.

U can do it online by using online 8 bit converter and u can use paint too or other wise you can customise the header.json but chances of bricks will be high

Another precaution is that you should always keep a screen protector on the mi band 4 as it is very likely to get scratch with time

No this is not really a precaution because everyone do not rough use it many users handle it with care or only use it for development and testing like me :) and i have mentioned the software related precaution here
