My opinion on this topic:
1st :
tarakanfw - Newbie account created 2 days ago - Thats a bad sign alreday
Why pay 2% dev fee ? Are my miners w custom firmware going to be generating more income ?
NOIm going to lose my warranty :
YESPay 2% just for better monitoring ?
YESThere is a possibility for a backdoor code in the custom firmware ?
YESCan i brick my miner flashing a custom firmware ?
YESThe only downside i see is potentially bricking the Miner when flashing it - not sure how possible it is.
Also not sure what bitmain says if you send in a bricked Miner with custom FW.
devfee will be about 2%
flashing procedure is like basic upgrade. moreover, the firmware is based on original image. so brick chance is the same
if you need to send your box by warranty -
upload the basic version and send it...
How the hell can i upload a "basic version" if my miner is totally bricked
