Re: hp elitebook 745 g6 amd bios unlock

I removed and tried RCUnlocker on the contents of what I think is U366, actually a W25Q128JV sitting snugly between the M.2 and DIMM2 slots, and I'm still locked out of setup.

In case it helps, here's what I did, essentially:

# flashrom --programmer buspirate_spi:dev=/dev/ttyUSB0 -c "W25Q128.V" -r spidump.bin
flashrom v1.3.0 on Linux 5.10.160-gentoo (x86_64)
flashrom is free software, get the source code at https://flashrom.org

Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns).
Found Winbond flash chip "W25Q128.V" (16384 kB, SPI) on buspirate_spi.

This flash part has status UNTESTED for operations: WP
The test status of this chip may have been updated in the latest development
version of flashrom. If you are running the latest development version,
please email a report to flashrom@flashrom.org if any of the above operations
work correctly for you with this flash chip. Please include the flashrom log
file for all operations you tested (see the man page for details), and mention
which mainboard or programmer you tested in the subject line.
Thanks for your help!
Reading flash... done.
# cp spidump.bin /path/to/usb/drive/hp_eb_745G6_U366_orig.bin
#

Then I dropped the file onto RCUnlocker.exe in an old Windows 7 laptop and copied it back in...

# md5sum hp_eb_745G6_U366_*
12ddd7780641c31293df20f614f963bd hp_eb_745G6_U366_modded_unlocked.bin

Reading old flash chip contents... done.
Erasing and writing flash chip... Erase/write done.
Verifying flash... VERIFIED.
#

Then I replaced the chip and reconnected the 2 batteries. Everything still works fine, but it didn't seem to act any differently. So I listed the actual changes made by RCUnlocker, which appear to be mostly sets of 0xff bytes swapped with sets of 0x00 bytes and vice versa, in the attached file:

# hexdump hp_eb_745G6_U366_modded_unlocked.bin -vC > unlocked.hxdmp
# hexdump hp_eb_745G6_U366_orig.bin -vC > original.hxdmp
# diff -u original.hxdmp unlocked.hxdmp | unix2dos > /tmp/hexdump_diff.txt
#

I couldn't easily find any RCUnlocker other than 1.0 in the first post of that thread, so that's what I used. Any light anyone can shed will be appreciated. Thanks in advance!

Exactly. The only thing left is to watch your chip burning process.

Re: hp elitebook 745 g6 amd bios unlock

I also tried HPUnlocker and it merely changed the earlier part identically, skipping those many groups of 0xff. Maybe it means this should be enough... I will try to flash again.

Re: hp elitebook 745 g6 amd bios unlock

TL;DR: It was U365. Take out the mobo and do it to U366 found in almost the same place under/opposite the SSD, not beside the SSD.

The silkscreen showed what appeared to be "U366" in that area, but after I took a decent photo and zoomed in, it was U368 ever-so-slightly misprinted by part of the 8 landing on a via. I briefly thought the IC definitely should be U365 because "U366" (U368) was farther away, and CN365 is right on top of it, as if a socket would go on that SOIC-8-like footprint that surrounds the WSON pads, and it had the same number as if for holding the same IC just in a different package. I compared it to this photo and didn't see anything that should match (the Parade chip). But I had to make sure, the hard way. The real problem is I didn't yet realize (or admit) I absolutely did need to remove the board, even though I had already seen another success and this note. Well, I also didn't think some Elitebooks had such similar innards.

My bad.

So I restored the backup of U365 after I (actually, finally) ran RCUnlocker on the image of U366. And it didn't tell me anything except 'ok, finished' unlike the first time when it wrote out quite a bit of information about the U365 image I gave it, which was weird.

Well, it's sorted now. Thanks, everyone!
