Hello, I'm looking for an old bios mod for the Thinkpad Z61m 9452-J3G, last official Bios version 2.27, with removed whitelist if possible? would be great to give it a last chance to survive )) Thanks and Cheers
Hello, I would like to reactivate a Lenovo Thinkcentre A55 (9265) with a Lenovo I946-F board (WinXP updating to Win7(10)) I have experience in Award Bioses, also worked on the Thinkcentre Phoenix bios with Phoenixtool 2.73 and reflashed the bios. Slictoolkit indicated an oem certificate error (yellow) I used a Lenovo 2.1 slic bin, but the certificate I think was 2.0. Could some one please post a suitable IBM/Lenovo 2.1 certificate (Lenovo slic 2,1)? Many thanks in advance
SLIC-dump ok in Slic-Toolkit? Screenshot? SLIC 2.0: can activate Windows Vista SLIC 2.1: can activate Windows 7. For Lenovo-SLIC 2.1 only one cert exists: LENOVO-68351C09.XRM-MS
Look at second screenshot: You have different marker and pubkey, they don't match, that will cause the signature error. So you have to find the failure while building bios. Lenovo- and HP-biosses are sometimes a hassle for mods.
@samamladen Your mod isn't complete. The stock 2OKT48A BIOS features the TC-2O pubkey, but we have yet to come across a complete TC-2O SLIC 2.1 binary dump. As a result, you need to manually hex-edit some modules to match the chosen Lenovo SLIC variant. @Serg008 modded this BIOS before, but unfortunately the download link isn't functional at this moment.
Many thanks for your info. This HEX editing would be too difficult for me and as a result: fingers off from Phoenix bios. All my Gigabyte boards went fine, even with Dell slics and certificates. Perhaps I send a message to Serg008.
After opening the bios-file with Phoenix-tool, you will find a DUMP-folder with many files (=parts of bios). You can edit files before pressing "go", perhaps only a few ID-strings, marker or pubkey had to be edited.
But in which area hex-editing? Change the Pub key in the Bios to match the slic file or change the key in the slic file to match the pub key? Tested in a hex-editor to change all TC-20 spots in bios file (no change to pub key at all) and to change all TC-xx in the slic file to TC-20 (resulted in a invalid digital signature of the file) and no effect after flashing. Didn´t find a tool to change the marker entry. Is there any?
Yes. Only difference to yours are some edited strings from "LENOVOTC-2O " to "LENOVOTC-5M " and i used a different SLIC-table, but for activation doesn't matter. Yours has the "LENOVOTC-5J"-table instead, what also should fits to the pubkey: MOD_4A00.ROM is the pubkey, which fits to all SLIC-tables from Lenovo; compare it in any hexeditor, the bytes from 24h to BFh are the same. So no need to change the pubkey, but the header is different, OEM-ID and OEM-table-ID. Your rw-report shows no active SLIC-table, not even for Vista. Before updating: Do also a backup with flashing tool.
