Re: "Cannot find Signature"... What's this?

1) While I am editing, can I close and open the PuTTY without danger while I have not saved the changes? (:wq)

2) Assuming the worst case, if a mistake is made, is it possible to reverse it? reinstall the firmware, set it factory default, and start over?

1- yes if you use the "x" bottom on top ,the setting won't be saved.

2- in theory the worst case scnerio is that you'll need to reset the miner. but still shit can happen.

since you are not going to do any coding , you shouldn't make any mistake, before you save just revise the code 2-3 times, compare it to the prev code you pasted here, make sure you have not deleted anything.

Ok, I ask you this since tomorrow I will post the edition step by step what you told me and ILL NOT SAVE THE CHANGE until you first see the code / photo and give me the approval. Wink

:wq where should write on ssh editor page? after this?

Code:

# if [ ! -f runme.sh.sig ]; then
   # echo "Cannot Find Signature!!!" >> /tmp/upgrade_result
#else
# openssl dgst -sha256 -verify /etc/bitmain-pub.pem -signature runme.sh.sig runme.sh >/dev/null 2>&1
# res=$?
# if [ $res -eq 1 ]; then
# echo "Installer Not Signtured!!!" >> /tmp/upgrade_result
#else
# if [ -f runme.sh ]; then
# sh runme.sh
# else
# echo "Incorrect firmware!!!!" >> /tmp/upgrade_result
# fi
# fi
#fi

if [ -f runme.sh ]; then
   sh runme.sh
else
   echo "Incorrect firmware!!!!" >> /tmp/upgrade_result
fi
:wq

like this?
Because I'm doing exactly the same and after writing :wq I don't close or closing the ssh editor and going to directly upgrade page D3 but still saying "Cannot Find Signature!!!"
By the way I can modify easier on the WinSCP program with editor and saving.But still got "Cannot Find Signature!!!" too at there.Can you make a video tutorial for this please?
