Hello, I changed the firmware to batch 1 after 24 hours the miner was cut down and no indicator is working. Now I can not enter the admin panel of the miner. Can you tell what can be done about it?
fan running

heat?
Power working at all

?
Yes fan and power supply working.
Do you think that I can try to recover from the SD card

Have you tried this method?
https://support.bitmain.com/hc/en-us/articles/115003595387-How-to-reset-miner-to-factory-settings-(Depending on where your SD-cardslot is placed you will use method 1 or method 3, read instructions in link for method 1 and 3 to decide which alternative is valid in your case.)
Recover from SD-card should be last option, I think!
