BSOD: Windows did not find any installed, licensed language packs for the system default UI language (0x0000012a)#

This error happens on all Windows 7 recoveries. It means the WIM doesn’t have language packs pre-installed. To fix this issue, you must download and integrate language packs in the WIM.

For Windows 7 recoveries (NTlite method):#

For this method to work, you must be on Windows 10 or 11.
Install and open NTLite.
Click on Free license and click on OK.
Click on Add on the top left, then Image (WIM, ESD, SWM), and open the WIM SVRP created.
Click on (select) 1. Sony next to the little indicator (should be gray). And click on Load on the top left.
Wait for the image to be fully mounted, a menu should appear when the process is done.
On the bottom right of the NTlite window, you should see sevice pack and architecture (x86 or x64) of Windows. Take note of that.
On the menu on the left side, click on Updates.
Download en-US (and language of recovery if your recovery isn’t in English US) language pack from here. Make sure you download the correct language pack (SP0 or SP1, x86 or x64).
On NTlite, click on Add on the top left, then Package files, then select the language pack executable(s).
Click on Apply on the menu. Then, click on Process on the top left.
The WIM will be rebuilt with the language pack(s) integrated.
If NTlite fails to integrate the lanugage pack(s), try downloading the language pack for the other service pack (SP0 if you downloaded SP1, and vice-versa). Make sure you’re on Windows 10 or 11, otherwise this process will fail!
Apply the WIM using this guide.

Alternative solution if NTlite doesn’t work (not recommended):#

Install and open Win Toolkit.
Click on All-In-One Integrator, and open the WIM SVRP created. Then click on Select on the bottom left, and Select [Sony]. Then Continue (No Preset) on the bottom left.
Click on Updates + Languages tab.
Download en-US (and language of recovery if your recovery isn’t in English US) language pack from here. Make sure you download the correct language pack (SP0 or SP1, x86 or x64).
Execute the language pack executable (exe), and shortly after it was opened, you should see a lp.cab file in the folder where the language pack executable is located. Select the file, and do CTRL+C and CTRL+V before it disappears. Do the same for the second language pack if you have downloaded two.
Rename lp - Copy.cab to lp1.cab (if you have two language packs, rename the second to lp2.cab).
Go back to Win Toolkit, and click on Add, Add Updates on the top left.
Select lp1.cab (and lp2.cab) and click on open.
Click on Start on the top left. The WIM will be rebuilt with the language packs integrated.
Apply the WIM using this guide.
