Bitmain Antminer L3+/L3++ firmware

Warning: Firmware is working with Antminer L3+/L3++

If you see the message: “can not find signature when you flash the ASIC with VNISH firmware” you need to take off bitmain software protection. This message means that your ASIC has BITMAIN firmware 2019 year that has overwrite protection.

If you have BITMAIN firmware 2019 you can try to remove the protection using signature_l3plus file or the SD card image (all files you can download from this page).

If during the flashing process (via the SD card) you can’t install the VNISH firmware (the 2 leds is not blinking) check SD manual one more time or change SD card. If this not help, most likely your control board is infected with a strong virus and you have to use a special recovery manual (SD card restore).

Previous Updates

Релиз 3.9.1

1) Implemented a new tuning algorithm, achieved high firmware stability.
2)Tuning works 50% faster and more accurately.
3) Fixed a bug with generating a large number of HW.
4) Significantly accelerated interface on chips.
5) Optimization of dev fee
6) Fixed a problem with the hotel with stratum+tcp, you can use any pools (we recommend AntPool, ViaBTC) that are able to set the complexity in the password d=512, d=1024.
7) Fix remote access problems on kinetics (without VPN directly by DNS name).
8)The tuner log has been increased to 50 event lines.
9) Fix rejects. The rejects are written in the miner’s log.

Release 3.9.0

1)A new tuning algorithm is implemented in the L3 + firmware
2)Fixed a bug with generating a large amount of HW
3)Added a signature to protect against viruses.
4)Added new profiles that do not require a tune
5)Saving the profile without a new tune when changing other settings
6)Add anthill. farm monitoring support
