Re: RCUnlocker
Hello to all friends and experts here,
I'm very scared and my fingers are shaking because I'm about to use the RCUnlocker tool that user RhethoricalCheese posted on this website
for my laptop: HP ProBook 430 G5 2VP86EA
Because I forgot the BIOS administrator password.
I disconnected the main battery and also the small cmos battery from the motherboard.
I use the Test Clip Cable with the XGECU T48 TL866-3G programmer.
The motherboard model is: DA0X8BMB6F0 rev F
The BIOS chip model is: Giga Device 25B127DSIG

Re: DA0X8BMB6F0 rev F , 25B127DSIG
Hello everyone, I have a difficult problem and need technical help:
Yesterday I ordered a sample programmer from Amazon: Xgecu T48 TL866-3G
This morning I received an email from the store: SETCTOP
They wrote that the programmer does not support the model of the bios chip of my laptop: Gigadevice HH1742 25B127DSIG AP15471 3.3v SOP8 208mil
And they wrote to me to cancel the order.

Hello hoaca388,
How can I know which model programmer can work?
I want to buy some programmer that can work and support my BIOS chip model but the stores don't answer me and I have no choice but to ask smart people here.
And what is the RC unlocker tool on this site that you mentioned? Where do I download it and is it suitable for every programmer?Leave a comment:

HP ProBook 430 G5 BIOS locked with admin password
Hello everyone, my name is Lior Levi and I live in Israel
This is my first time here.
I have HP ProBook 430 G5 2VP86EA and it's BIOS locked with admin password. no way to upgrade it but I'm enable to use the laptop and enter Windows 10. just the bios is locked.
The global manufacturer refuses to help me
The local lab wants to replace a motherboard for twice the price of a laptop.
I disassemble my laptop and removed the main battery and CMOS battery for few days but still the BIOS is locked.
