You are using SHA-1 encrypting in the code you posted. Which is what my example you used does... not SHA-256. The correct value for SHA-256 encryption is
6ca13d52ca70c883e0f0bb101e425a89e8624de51db2d2392593af6a84118090
for an input value of:
abc123
Your requirements go far beyond just a regular SHA-256 hash and several components of those instructions make little to no sense to me. They appear to be written for some specific platform rather than a generalization...
Step 4. The notion of removing a binary '0x' doesn't make sense, but lets assume that this just means that we want to convert the byte array produced in step2 to a string of hex values in the form of
6ca13d52ca70c883e0f0bb101e425a89e8624de51db2d2392593af6a84118090
rather than
0x6ca13d52ca70c883e0f0bb101e425a89e8624de51db2d2392593af6a84118090
No matter what, this isn't 'binary'
Next, we want to convert that value to lower case, so step4 is ultimately equal to
abc1236ca13d52ca70c883e0f0bb101e425a89e8624de51db2d2392593af6a84118090
or are we expected to somewhere convert the result of step 1 to a hex string as well?

Is this then meant to get hashed with SHA-256 as a string or as a byte array of itself? Very unclear instructions...
Finally in Step 8, I've never heard of anything called ME998 before, so, I am left to assume this is some internal system or table to your environment.
Regardless of the method I tried as outlined above, I cannot produce the 'expected' output you provided.

I would recommend you get some clearer hashing requirements
