You read it right, here's a functional port of BDS Menu for Lumias unlocked using WPInternals.
Note: I observed some weird behaviors on early x30 devices, including prototypes that had BDS menu out of the box, where the menu would simply act like if it was broken.

The bootarm.efi loader has been taken from the grub package posted here and modified to load menu.efi instead of boot.efi, credits belong to the original person that developed this efi in 2016.

Note: attached two variants, a normal one (fs3) and a fs4 variant, if you get an error about the menu not finding its configuration files, please try the other variant.

Installation instructions:

• Download the files attached in this post.
• Place all files downloaded in the EFIESP partition of your phone.
• Configure BCD exactly like this to have an entry loading BDS menu:
  
  
• Load the entry using your favorite method.
• Have fun.

That shim file might not work on 950XL, it simply reboots my phone - haven't figured out why, probably due to new CPU architecture or the firmware itself

Thanks gus ,
you can also restore the USB Mass Storage picture by adding attached bmpx files in EFIESP\Windows\System32\BOOT\ui.

Load the entry using your favorite method.

How?

 

[gus33000]

How?

To be fair as some of the capabilities of BDS menu can be very destructive (hence the big disclaimer), if you really don't know how to do this, then you may stay away from it, it won't bring you anything cool

Please, y have the lumia 530 lab rat.

Nevermind, ill modify EFIESP\efi\Microsoft\Boot\bcd using visual BCD.

You shouldn't use visual BCD. Use BCDEdit since some of the options aren't available and Visual BCD isn't built for phones.

Note: currently looking at a problem where the block id for efiesp might differ between phones, if you get an error message saying can't load menu configuration file, please tell me your device model.

Edit: Fixed for some other problematic devices, I'll send an alternative version of the menu to see if it fixes it for most with the two variants

Yes same problem on 950.

Could you explain how to configure bcd using bcdedit please?

Could you explain how to configure bcd using bcdedit please?

like this...

also need add device
bcdedit /store .\BCD /set "{7e1bd2b8-0ab0-11e8-aa3b-1c3947b79a68}" device partition=f:\efiesp
and(in my case) add it to customactions( activation by vol up/down )
bcdedit /store .\BCD /set "{bootmgr}" custom:54000002 "{7e1bd2b8-0ab0-11e8-aa3b-1c3947b79a68}"
(custom:54000002 == vol down, custom:54000001 == vol up)

The first time a came across this menu was on the Mi4 W10M rom. Thanks for sharing this.

 

[prokakavip]

Does not work on my lumia 950 it just seems to fit into ARM V7 with 32 bit architecture

 

[augustinionut]

Someone can copypaste those commands instead of attaching pictures?

Nevermind, i OCR that photo:
PS I:\EFIESP\efi\Microsoft\Boot> bcdedit /store .\BCD /create /application bootapp
xxxxxxxxxxxxxxx succesfuly created
PS I:\EFIESP\efi\Microsoft\Boot> bcdedit /store .\BCD /set "xxxxxxxxxxxxxxx" path \efi\bds\bootarm.efi

PS I:\EFIESP\efi\Microsoft\Boot> bcdedit /store .\BCD /set "xxxxxxxxxxxxxxx" description "BDS Menu"
PS i:\EFIESP\efi\Microsoft\Boot> bcdedit /store .\BCD /set "xxxxxxxxxxxxxxx" locale en-us
PS i:\EFIESP\efi\Microsoft\Boot> bcdedit /store .\BCD /set "xxxxxxxxxxxxxxx" inherit "{bootloadersettings}"
PS i:\EFIESP\efi\Microsoft\Boot> bcdedit /store .\BCD /set "xxxxxxxxxxxxxxx" nonintegritychecks yes
PS i:\EFIESP\efi\Microsoft\Boot> bcdedit /store .\BCD /set "xxxxxxxxxxxxxxx" testsigning yes
PS i:\EFIESP\efi\Microsoft\Boot> bcdedit /store .\BCD /set "xxxxxxxxxxxxxxx" isolated context yes

PS i:\EFIESP\efi\Microsoft\Boot> bcdedit /store .\BCD /set "xxxxxxxxxxxxxxx" device partition=i:\efiesp
PS i:\EFIESP\efi\Microsoft\Boot> bcdedit /store .\BCD /set "{bootmgr}" custom:54000002 "xxxxxxxxxxxxxxx"

I run efi shell with simple script(for run another efi file) and shell thrown "security violation"...

[BlueTR]

I can't edit bcd file no matter what I do. Cmd and ps keep saying access denied.

Same thing with 950. It just blinks and nothing happens.
