I want to port UEFI to my Pixel 4 XL,but I can't find the porting guide. about msmnilepkg

[sunflower2333]

Hello. I do not suggest porting it to pixel. You UFS will be erased if you add UFSDXE. So, it's very dangerous. The porting guide is on the way. I can provide a quick note. Quick Note: 1. copy nubia-tp1803 to google-coral. (Brand-codename). 2. Remove all files under google-coral/CustomizedBinaries & google-coral/PatchedBinaries. 3. Extract files from your device's xbl and put them under CustomizedBinaries. 4. Enable MLVM in Defines.dsc.inc 5. Edit resolution in PcdFixedAtBuild.dsc.inc 6. Remove UFSDxe part in DXE_Spec.inc. 7. Patch your device's dxe and put them under PatchedBinaries. 8. Replace tp1083.dtb with coral.dtb (you can find your device's dtb in /sys/firmware/fdt.) 9. ./build_uefi.sh -d google-coral -s <ram-size> 10. fastboot boot Build/google-coral/google-coral_xG.img Again, if you added UFSDxe, there is a high possibility that your ufs will be erased.

I see.But I still have these questions:

1. How to extract xbl.img ? From the stock ROM or device ? If I need to extract it from my device, how to ?
2. How to patch my device's dxe and put them under PatchedBinaries ?
3. I can found my device's DTB, do I need to do anything extra with it?
4. Which build environment should I have ? Still use Ubuntu 20.04LTS?
5. Can I boot Windows 11 from external storage devices like USB Drive ?
   Help me please.

[sunflower2333]

1. - excute dd if=/dev/block/by-name of=/sdcard/xbl.img on your phone. - copy or move it to your computer. - right click -> 7zip- > extract -> #:e -> 4.gz - you will see all efi files in 4.gz 2. How to patch: - You can use IDA to patch it. I think the old guide has it. - To know where needs patch, you need to refer other devices: ``` hexdump -C a.efi > a.txt hexdump -C b.efi > b.txt diff a.txt b.txt ``` - a.efi is original binary, b.efi is a patched binary. - The diff will tell you where and how to patch. - Find the same function in your device's dxe. - Patch it with a tool. 3. - Nothing to do with your dtb except rename. 4. - As you can see in the README.md, if you do not have ubuntu20.04 , you can choose docker. Or, you can use github workflow. I haven't tested other higher verisons or other distros. 5. - boot from USB is not available, because the usb mode in uefi is peripheral. - boot from SD, I do not know. Maybe SdccDxe needs patch. You can have a try. Sunflower2333.

That makes me more clearly to build. But I still have 3 questions left:
1.My phone is running LineageOS , can I use Lineage OS's DTB and xbl.img?
2.If I can't , my phone's stock rom has multiple Android versions, from 10 to 13. Which version I should use to extract DTB and xbl.img?
3.According to step 2, What is IDA? How can I find the dxe in the same function like my device's dxe ? Which tool I need to patch?
I'm sorry to trouble you, but I'd appreciate it if you could help me.

[sunflower2333]

1. You can use the dtb and the xbl.
2. IDA is the tool. Or you can choose Ghidra.

[Android-Piepaint]

Thanks for helping me!

[sunflower2333]

You are welcome. If you do not have other issue, I'll close this issue.

[Android-Piepaint]

Well, I have finished building,and I got the UEFI image, however, it refuse to boot on my Pixel 4 XL. Why? Did I did something wrong?

[Android-Piepaint]

By the way, someone let me do these.

[sunflower2333]

拒绝启动？你可以fastboot devices看一下启动没启动。如果启动了，fastboot devices是看不到设备的。如果可以看到。。那就是dtb问题了。
至于ufs啊，你需要patch ufsdxe，虽然我不建议。如果patch了，你可以在uefi使用ufs，但是如果你使用uefi启动什么系统（比如win或者linux），然后那些系统上的驱动尝试调用ufs，你的ufs会被擦。对于windows，你需要在dsdt里面删掉，

iasl DSDT.aml

会生成DSDT.dsl
删除其中的Device(UFS0){XXX}那一大块就好了
然后

iasl DSDT.dsl

编译回去

[Android-Piepaint]

Fastboot 提示error boot prepare ，直接boot 的話ADB 會提示無法校驗映像...那真正的DTB到底怎麼提取？

[sunflower2333]

那还真是稀奇，没见过，/sys/firmware/fdt那个fdt应该是可以启动的 Sunflower2333.

是不是DTB複製到電腦的時候出的問題？好像要用ADB命令複製？

[sunflower2333]

应该没区别吧，你看看sha1sum呢 Sunflower2333.

那要怎麼看呢？

[sunflower2333]

你提取一份到电脑上，看看他的sha校验码 然后对手机里面那个用 ``` sha1sum fdt ``` 这个命令可以得到fdt的校验码。我觉得应该不会有啥问题 Sunflower2333.

校驗了，是一致的，但就是無法啟動。會不會是重命名方式的問題？
