So yeah, the procedure seems to be still doable.

Looks like I did not want to delete anything I had found, though it is not needed to get the downgrade done.

Follow these simple steps:

on Win 7 or earlier :

1. Grab a USB stick and format it FAT32 with the hidden DOS system files on it.

I think I used HPUSBDisk.exe and the files from usbdos.zip while running some Windows OS.

2. Copy over all needed files.

 You will need at least PFLASH.exe, B146.FL1, B146M.FL1 and the TP directory with the winflash.exe.

3. Boot from your USB device into DOS.

4. Type in: PFLASH /sa B146.FL1 (This should downgrade your T420 to BIOS 1.46)

5. Boot into Windows again, open a DOS window and navigate to USB/TP/bios_mod.

6. Type in: winflash /sa B146M.FL1

From the winflash GUI, select "Flash BIOS only" then click on the "Flash" button.

That should be it - reboot and enjoy your modded BIOS.

You may have guessed that M stands for the modded BIOS you finally want.

Besides the whitelist removal, some AMT features are also disabled with the mod.

 

Good luck!

 

For the rare possibility that you already ditched all your Windows installer DVDs:

The Internet Archive has one here: https://archive.org/details/HPOperatingSystemDVDWindows7ProfessionalSP164-bit650434-DN32012

No serial needed, but the install is not a "genuine" W7 of course. ;)

 

HPUSBDisk.exe

usbdos.zip

OpenMe.iso

 

@tluck : I think this procédure (goodguess' one) is great and may be added to your guide for those as me who update there BIOS to newer as 1.46 (DOWNGRADE)

 

@goodguess : THANKS AGAIN for your help :thumbsup_anim:

:thanks_speechbubble: thanks to you my DELL 1510 (BCM94322HM8L) is fully working now :-) :thanks_speechbubble:

For Europeen users : do not use channels 12 and 13 in 2.4GHz, if your BCM94322HM8L card come from China.

this huge tip was brought to me by goodguess too :-)

@goodguess

I've done clear install, so that should be fine. System freezes are suddenly gone after few reboots, so it's really weird. But now I'm getting random graphic glitches (see picture attached), it is happening only in Firefox so maybe it's just its own problem. I'll probably try to install High Sierra instead as it seems to be more stable for now.

@goodguess hmm. yeah just verified the odd behavior with JPG files. never noticed it before

 

SO switched the model to MBP9,1 vs MBP11,1

- jgp view works in Finder and Preview as well 

nightshift still works etc and will update as expected 

- mojave compatible.

 

I have not tried to see if running as MBP8,1 is more stable. I will run with mbp9,1 for awhile to see if it works better.

 

@bxe if you have 1600x900 LCD then maybe inject the "2e3" EDID. that ism,  move config.1600x900.2e3.plist to config.plist (default)

Thank you, Goodguess.  I'm running installs while I wait for the new wireless card.  I'm not getting any bluetooth right now, are there steps to get the onboard bluetooth working?

 

Also, my trackpad is working, but I'm not getting single touch, just x and y movement.  Any ideas?  Synaptics hardware, I believe.

what model do yo have?

 

if you read the guide, you will see the note:

Enable (turn on) Bluetooth so the green light is showing on the LCD bezel (do from Windows or Ubuntu).

  • Also make sure the side switch is set to green too!

on trackpad - use the apple system prefs to turn that feature on under trackpad - called tap to click

Bluetooth: This can't be accessed in the BIOS by chance, can it?  I guess I'll have to make a USB bootable OS

@namisloc 

what model laptop do you have? 

what version macOS? 

did you put all the zip contents into the ESP as is?

Sorry friend, I meant to put my build in my signature before making my last post.

 

Bluetooth is working, however I'm unable to access any trackpad preferences.

 

My BIOS was 1.49, and I downloaded what I thought was a 1.52 whitelisted mod, however it rolled my BIOS back to 1.41.  Now, it's a modded 1.41, I have access to the advanced menu and whitelist removed.  Sierra installed smoothly so I decided to just leave it be.   I wanted the modded BIOS because I have 2x8gb DDR3 and an AR9280 on the way.

The EFI folders were copied to ESP.

Good you got your hack working so far, namisloc!

Did you repair/refresh kext cashes fequently?

If no, use Kext Utility to maintain system files after any changes you made to your hack.

I´ll attach Kext Utility, just in case.

 

Sierra is probably the best OS for a T420.

If you have a spare SSD, you may always clone what you got and upgrade the clone to HS or Mojave, if you feel the need.

 

A Atheros WLAN mPCIe should work as Airport.

I´m using these, as they are supported OOB:

Why your trackpad does not show up, remains a riddle to me. I have got a 4336-5U2 with everything working.

EDIT:

Went back to Sierra and the Trackpad setting there is not found either.

Lenovo Trackpoint and Touchpad, do work though. ;)

Tluck & all other contributors - Thank you for your work in keeping this topic current and for the work past/present.

 

I have been attempting to upgrade from El Capitan (HDD) on my T420 to High Sierra (SSD), but am unable to get the Dell 1510 card working with the 1.46 Bios mod.  I have attempted to use the Wifi kext through the kext utility2 from RehabMan with the FakePCIID kext as well with no luck.

 

Now that I punched my old HDD in to post, wifi does not work again so using a secondary PC.

 

Everything else appears to work on HS (bluetooth, good video) just need to do the iMessage fix but don't want to do that until I get the wifi working.

 

I may just pull the trigger and jump to Mojave, but wanted to talk to you all first.  Let me know what other PC info you needed/code run in order to help troubleshooting.  Thank you in advance.

 

PC Specs:

CPU: i5 - 2.59 GHz

RAM: 16GB 1333 MHz

Graphics: Intel HD 3000

did you properly install the HD3000 in /S/L/E? if not you may not have fully accelerated graphics QE/CI with Mojave

@leaddonkey

 

did your wifi work before you upgraded from el cap to high sierra? if so, then maybe missing a kext?

 

@Dabman1988

 

moving to Mojave is almost as easy as upgrading from Sierra to HighSierra. but i dont know about nvidia ? other than to recommend to disable it.

1) update your ESP with a recent version

2) get your current system running with a mojave config.plist which essentially means you change the model from MPB8,1 to MPB9,1.

3) install Mojave

4) on the post install side you need to install the HD3000 in /S/L/E.

 

all of this is outlined in the Guide.

I saw that the latest EFI has HD3000 in EFI\CLOVER\kexts\10.14\ , if I have already installed the HD3000 in the /S/L/E and than update EFI , will it affect?

@tluck - It did work in El Cap prior to the change.  I tried porting over the IO80211Family.kext from El Capitan to High Sierra for the Broadcom BCM94322HM8L.  I checked a few forms and did not see it on the list of kext which Apple did not bring forward and the data from https[:]//wikidevi[.]com/wiki/Broadcom_BCM94322HM8L showed BCM94322HM8L - 14e4:432b 802.11abgn 2T2R.  Still not working, so back at it in the morning. Thanks for any/all the help.

 

Also, tried bringing over my old config.plist to see if it "magically" worked for wifi.  It did not, but my Serial # came over, so one less thing to do!  (It's the little wins!!)

@leaddonkey - get these kext from the T460 repo vs T420 - 

 

these 4 kext may make it work:

FakePCIID.kext

FakePCIID_Broadcom_WiFi.kext

BrcmPatchRAM2.kext

BrcmFirmwareRepo.kext

 

@tonyyang123 - the HD3000 kexts are in the kext/10.14 folder just as part of the zip (people asked for them instead having to get them from a High Sierra install) - they don't work right fully unless you put them in /S/L/E in my experience.  

 

so having these kexts duplicated in ESP is ok - the ones in OS /S/L/E should be used

So tried the kexts from the T460 repo and did not work.  Dug into some of my old notes from El Capitan (again thanks tluck) and ran lspci on a Ubuntu USB and noticed that I am running BCM43224 [14E4:4353] which is the DW1520.  In reviewing other forums it looks like it might not work too well in High Sierra.  Trying to force load the \System\Library\Extensions\IO80211Family.kext\Contents\Plugins\AppleAirPortBrcm43224.kext from my El Capitan HDD.

 

I have the hex and a few other screenshots if anyone has a way to Force the kext to load or alter my kexts to patch.

 

Side Note:  If you got a system running, save that exact setup and write some notes in a textpad file.  Never know when you'll have to dig deep due to a fubar HDD or just because you want to upgrade and it doesn't work on that 1st attempt.

 

If this fails two questions:

1) Any other thoughts?  If not,

2) What is a good Half mini pci card that'll work in both High Sierra and/or Mojave?  want to attempt to "future" proof a bit because I like my hackbook!

 

Thank you all.

@leaddonkey I have the same card, DW1520 will work almost OOB, without any extra kexts in Sierra/Mojave with just a small config plist patch:

            <dict>
                <key>Comment</key>
                <string>DW1520 Whitelist Patch (MBP11,1)</string>
                <key>Disabled</key>
                <false/>
                <key>Find</key>
                <data>
                TWFjLTJFNkZBQjk2NTY2RkU1OEM=
                </data>
                <key>Name</key>
                <string>com.apple.driver.AirPort.Brcm4360</string>
                <key>Replace</key>
                <data>
                TWFjLTE4OUEzRDRGOTc1RDVGRkM=
                </data>
            </dict>
 

If you use for example MBP9,1, as tluck suggested recently, you will need to change the replace data appropriately (base64 encoding of Mac Board-Id). For MBP9,1 use 

TWFjLTRCN0FDN0U0Mzk0NTU5N0U=

 

For El Capitan search here for DW1520, you will find the solution with MBP8,1.

Not sure what you mean by optimizing it, I have this one too and it works out of the box, nothing needed (besides bios whitelist removal of course).

Thats what I was asking myself either.

So far my two DW 1510 were working oob since ElCap IIRC.

If a config.plist edit would show the card as Apple instead of "Third-Party Wireless Card" it might be nice to have.

If channel 12 and 13 in the 2.4GHz band could be enabled that way, it would be a real improvement.

(I doubt that, flashing the card will be needed - not worth the hassle, I would suppose.)

 

MBP 8.1 / 9.1

On my side, re-enabling Preview is bettering things a lot.

However, I feel that a config.plist with MBP8.1 or MBP9.1 slows down things compared to MBP11.1.

E.g. opening "About This Mac" or inserting a text string here by copy/paste seems to lag for a second or so.

Which setting do you use or like best for Mojave?

      buon giorno 
      spero tu mi possa aiutare ,perche' non riesco piu' a far partire i miei 2 ssd 850 samsung sui quali highsierra funzionava perfettamente da 1 anno e non ce' maniera di farlo ripartire .unica cosa e' che riesco ad arrivare alla console dell'istaller e ho tentato varie volte di ripristinare da una time machine che ho salvato su un altro disco usb .
      il mio sistema e' un asus p5qd turbo ed e7500 dual core . grafica gtx1050 chr funzionava con accelerazione e webdriver nvidia .audio voodoo 282. e boot clover che e' sempre stato il 5103 che poi  ho aggiornato a 5120 proprio il giorno prima che succedesse il fattaccio .quel giorno ho aggiornato dal sito apple la comboupdate 10.13 .6 da 10.13.4 .e qui al riavvio boom niente diski in clover nn li visualizzava piu .ora sciacciando f3 visualizzo il preboot e lssd con highsierra aggiornato ma arrivato alla console andava in reset loop .
      a questo punto riesco a ripartire togliendo l'accelerazione .e installando i nuovi webdriver di nvidia aggiornati all 10.13.6 .
      al riavvio non parte piu' con accelerazione e sempre problema in clover dei diski ma riuscivo a partire con f3 e preboot .
      ora decido di installare da time machine e tornare alla versione 10.13.4 del giorno prima ..e al riavvio niente piu dischi ne preboot .sono fermo a questo punto ..riesco solo a far partire installer ma nn so i comandi da dare in terminal per aggiustare le cose . ho anche linux su un altro notebook. ti ringrazio anticipatamente per l'aiuto .

      So, here's what i think clover do when it patch ati framebuffer, first it read a cached kext, then it search the original hex value of the connector, then it changed the value with the new one. Is it correct? now, here's what i find confusing... let's say that i want to patch AMD7000Controller.kext, in that kext, i want to patch "AJI" framebuffer with a new value, so clover try to find the hex value of "AJI" connector then replace it with the new one, simple right? but when i search the AMD7000Controller binary file for other framebuffer, some of them didn't exist in the binary, for example, i tried to patch "Ramen" framebuffer, from various source, it said that:
      Ramen (6) @ 0xeba70 LVDS, HDMI, DP, DP, DP, DP 020000000001000039050108000000002001050600000000 000800000402000000010200000000001000030500000000 000400000403000000010343000000001102010100000000 000400000001000000010431000000002103040300000000 000400000403000000010563000000001204020200000000 000400000001000000010651000000002205040300000000 So i open a hex editor and search for:
      020000000001000039050108000000002001050600000000000800000402000000010200000000001000030500000000000400000403000000010343000000001102010100000000000400000001000000010431000000002103040300000000000400000403000000010563000000001204020200000000000400000001000000010651000000002205040300000000 but, it turns out that hex editor couldnt find that hex value in AMD7000Controller,

       
      most of the framebuffer exist in the AMD7000Controller, but some doesnt, If this is the case, then, where does clover find the original framebuffer to be patched? am i missing something?

      Lenovo T460 macOS with Clover Guide
      Latest Release on GitHub (July 2020) Updated to Clover r5120 Updated Lilu based kexts - Lilu, ALC, WEG Added AirportBrcmFixup.kext
        Various Tweaks over Last months The main branch in my github repo is a complete Clover ESP (/EFI) bundle and kext pack for the Lenovo T460. The current file bundle seems to work on Sierra, HighSierra, Mojave and Catalina. There is an OpenCore branch in the repo as an alternative to Clover. This guide was developed for a Clover implementation. But the thread has evolved to include discussion of both Clover and Opencore for these systems: T460 and T470 family of ThinkPads.
       
      Full Clover file set - config.plist etc. Includes all custom kexts Includes custom DSDT/SSDT scripts and patches Utility scripts The zip bundles are posted to GitHub: https://github.com/tluck/Lenovo-T460-Clover/releases
      Caveat: The T460 systems used here was configured with: i5-6300U, Intel HD Graphics 520, 1920x1080 touch screen. If you have a different system model, then extract the ACPI files and use the included scripts to create a set of files consistent with your system type and BIOS version. See below for details.
      Credits: RehabMan, Shmilee, vusun123, TimeWalker, Mieze from which, much of their work and help is/was was used to get the T460 to this point.
      Devices and aspects working:
      Ethernet -  Intel I219LM is enabled via IntelMausiEthernext.kext WiFi/BT - substitute the Intel WiFi/BT with a compatible Broadcom or Atheros chip Audio - ALC293 codec implemented via AppleALC.kext (the old AppleHDA_ALC293 and CodecCommander kexts are not needed) PS2 - ClickPad + TrackPoint + all 3 buttons - using a modified VoodooPS2Controller to support new layouts - and added some custom Fn key maps based on 440/450 dsdt USB - implemented via custom SSDT + USBInjectAll kext. All USB3/USB2 ports are intel-based and work -  3 external USB and internal Camera, BT, etc  Sleep/Wake - the sleepwatcher package and custom sleep/wake scripts are used to help with sleep/wake for BT and PS2 devices. Note: have not tried to implement the SD card reader - no driver found.
