braiins aftermarket is good
and the epic controller aftermarket is good.
I get them from altairtech.

Currently not, but be aware of future releases. If the miner is working with factory firmware, its best to not update it. Yes, a future update could potentially lock them again.

Is this still an issue when considering buying a miner?
What about used machines without exact knowledge of firmware update history?
How about new S19 machines? Could they be locked down against using third party software?

Ok, it’s been over a year now. Is there any movement on being able to flash custom firmware in s17/S19 models yet?
Yeah our S19 firmware has been in beta for over a year and on public release for the past 4-5 months? We have the full product line support for the S19.

S17s were done last year (via unlocker or sd card), S19s are work in progress.

There are a few workarounds. All of them will probably remain private until S19 firmware is ready so it will be too late for them to patch it again. There is hope... Shitmain sucks at locking down their stuff

Once again Bitmain attacks its customers. In another attempt to prevent people from switching firmware, last week they pushed an update that makes signature checks in sd updates.
It is very likely that the same thing will spread to all other Bitmain models...
Of course this means the firmware community will have to find a solution (again). If i were to guess, using the serial port...
Remember, DO NOT upgrade the firmware on your S17, T17, + or not, pro or not.
I'm sure the community will find a solution, it always does. But it might not be easy, and might not be pretty. Protect your investment, don't let the manufacturer decide what you can and what you cannot do with your equipment.
At worse, the whole controller would need to be replaced.
PS: History repeats: make sure you don't upgrade fw to the S21 family as well for the same reason.
Any firmware from April 2024 onwards locks the miner, do not be tempted with "hashrate % slider", its the usual bait.
PS2: Also S19.

Bitmain has pushed new s17+ firmwares 18th of june (and eventually will update s17 too) where it seems sd card updating does NOT work anymore! Be careful, dont upgrade your miners especially if you are looking forward to try braiinsOS for s17 soon. We will have a closer eye on the situation.
A week ago we already noticed additional security in place in the s19 firmwares, signature checks in sd upgrading, hoping nothing will be carried over to s17.

It’s implemented on the hardware level, xilinx SoC chip supports secure booting by verifying the signature of the boot loader and FPGA bitstream. Bitmain activated this feature in s19’s

Unless you have the private key to sign your firmware
...
you just need to replace the Xilinx chip with a new one
