That is incorrect.
OTP is write once area that starts with all binary bits unset value 00
When all binary bits are burned you have FF
You can only burn more bits so you can only move towards FF,

Tools tend to avoid OTP but the statement that no TOOL can write to this EVER is not TRUE

My bad, let me rephrase that: no OBD flash tool can EVER write OTP areas that have been programmed and set as OTP. EVAR.

Yes they can, just that they can only go one way with it.
Let me rephrase your comment Smiley No tool can 0 OTP bits that have been set.

Friends what are main differences between SGM and SGO files?

There is a tool used to extract SGO file. Who can get it and post it here?

lol I don't think Revo internal tools were ever meant to become public domain.

Same could be said about many pieces of software that we interact with.

I can count on one hand the number of people who publish their code in this so called "community".

frf-to-odx is done inside SoxUtil.dll (odis or DTS7)
...
key.bin is inside the resource area

I see that soxutil.dll calls a function with a "\\key.bin" entry but no file exists.
Is the resource inside the .dll?
.rsrc/1033/FILE/1002 holds 4k of binary info, is this it?

Thank you

Still looking for an answer for this.
I can't find any resource linked with key.bin.
How about a hint if you can.

Also, to unpack "BCB Type1" compressed data:

import sys, struct

key = "BiWbBuD101"

img = sys.stdin.read()
img = img[img.index("\x1A\x01") + 2:]
img = ''.join(chr(ord(j)^ord(key[i%len(key)])) for i, j in enumerate(img))

p = 0
res = ""

while p < len(img):
  l = struct.unpack(">H", img[p:p+2])[0]
  p += 2

  fl = l >> 14
  l &= 0x3FFF

  if fl == 0: # literal
    res += img[p:p+l]
    p += l
  elif fl == 1: # RLE
    res += img[p] * l
    p += 1
  else:
    sys.stderr.write("remaining bytes: " + img[p:].encode('hex') + "\n")
    break

sys.stdout.write(res)



I get:
    l = struct.unpack(">H", img[p:p+2])[0]
TypeError: a bytes-like object is required, not 'str'

I used an odx file created by VAS File Decoder.
This is in the source:
[FORMAT]
BCB Type1 (C) R. Bosch GmbH 2000 K3/EMW3-Ws
[START_ADDRESS]
80020000
[END_ADDRESS]
8027FFFF

you might need an 'img=bytearray(img)' somewhere to convert the string to a byte array

Thanks for the idea.

I placed the line just before the 'while'.
I got a TypeError because didn't include the "optional" encoding. Hmm?
So I:
img = bytearray(img, 'utf_8')
also tried utf_16 and ascii

Each fail when it hits a char it can't encode.
Too bad I can't:
img = bytearray(img, 'hex')

I am not entirely sure that chr() here:
img = ''.join(chr(ord(j)^ord(key[i%len(key)])) for i, j in enumerate(img))
can handle the extended char set (>127)

But I don't know python.

maybe something like
Code:
from array import array

img = array("B", img)

you might have to learn python for this.. if i have time I might try to fix it for you but i'll need the stuff you're working with

Very kind of you but that would use too much of your time.
I can't even be sure of the script's efficacy.
I will work on my understanding of Python.
