![]() So, how does RCUnlocker work? Or is that a secret?
![]() I have some guesses, but they're rather extravagant. Occam's Razor and all that. |

![]() No need to use your imagination. Just compare files using hex editor

![]() I think I got it.
For HP, you erase the NVRAM region (not entirely sure how this is detected) For Chromebooks, you flip the devmode and enrollment bits (I guessed correctly!) For Apple devices, you clear a 289 byte region starting with 0xAA557F00 (maybe HP works the same way - clear a XXX byte region starting with 0xYYYYYYYY) Very cool ![]() EDIT: Ah, yes. For HP, it wipes a region starting with a bunch of 0xFF and "NvramActiveRegn", and ending with [something I didn't bother to remember]. Sure would've been nice if you had uploaded this as a Python script instead of a PE executable, so I wouldn't have had to open up a Windows VM and copy a bunch of files back and forth to "reverse-engineer" this XP Last edited by unilock01; 11-19-2021 at 09:01 AM.. |

It will create a new file in the same directory as your bin file. It will be named [BinFileName]_unlocked.bin |

![]() Your verification has nothing to do with the unlocker. It's just that ch341a can be quite unreliable. Check your connections.
Missing unlockable content means the program didn't find any keywords it was looking for. That suggests you are trying to unlock something which either is not supported or you just have a faulty read. So maybe help us and give some more information. Like what are you trying to unlock and what is your file like. |

I'm not trying anything fancy.
Maybe I'm missing a configuration in the NeoProgrammer? If anyone could try it out to see if your able to unprotect and verify without verification error that would be really appreciated. org.zip thanks for your help and support ![]() |

![]() Might be a stupid question but... Have you tried programming instead of just verifying?

![]() Korreia, please describes what steps you take. It should be read, verify, patch, erase, write, verify.
adil12, as I said, you either have a faulty read or you are trying to unlock something which is not supported. So please do help me help you. What are you trying to unlock? Upload your file. Did you verify your readout? |

Would this work with your tool ?? copy the last 16MB Hex code ( 1000000h lenght ) from the 32MB file and paste it in a new empty hex file in any hex editor and save it, then use the RCUnlocker to unlock the saved file (16MB), then in the original 32MB dump paste/write the last 16MB with the generated file, would like to try it but i have no case for now on which i can test that. will appreciate it a lot if you can test that, thank you very much in advance, if no time for that just ignore my request will test that whenever got a case with 32MB and 16MB ones . |

![]() Hahahaha. The issue is that you need to modify 16MB chip. Yes, there is a way to do it using the 32MB chip but not like this. Why don't you just patch the 16MB chip? Too difficult to unscrew the motherboard?

![]() Hello,
Your tool works on the older generation of Probooks but i can't get it working on g8 as both ec and spi roms are 32mb, i might need some help from someone more skilled than me. If anyone could give me some advice or give me a hand, i would really appreciate ! ![]() I'm attaching the dumps from my computer in case you want to have a look at it ! Thank you ! |
