| This source was initially found at mingwork.com, Logitech were the ones working on it with another company. | ||

| What's this? | ||
| ================== | ||
| This is a repository which contains the source code for the firmware of the SoC (System-on-Chip) Qualcomm Snapdragon 660, also known as SDM660. | ||
|
|
||
|
|
||
|
|
||
| Build Components | ||
| ================== | ||
| * LA.UM.8.2.1.R1: "LA.UM.8.2.1.r1-04200-sdm660.0-1" *(Unavailable in this repository, fetch it from CAF yourself if you wish to build android with this source.)* | ||
| * ADSP.VT.4.1.C1: "ADSP.VT.4.1.c1-00009-SDM660-1" | ||
| * BOOT.XF.1.4: "BOOT.XF.1.4-00280-S660LZB-1" | ||

| * CDSP.VT.1.1.C1: "CDSP.VT.1.1.c1-00005-SDM660-1" | ||

| * WLAN.HL.3.3.5: "WLAN.HL.3.3.5-00149-QCAHLSWMTPLZ-1" | ||

||
| How do I build the bootloader? | ||
| ================== | ||
| * Well first off you need the dependencies used for building Android, you can install them by using the command below. | ||
|
|
||
| sudo apt install python2.7 git-core gnupg flex bison build-essential zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 libncurses5 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z1-dev libgl1-mesa-dev libxml2-utils xsltproc unzip fontconfig uuid-dev sqlite3 iasl gcc g++ nasm libtinfo5 | ||
| * If you had installed them before, you may skip this command. | ||
| * After installing the normal dependencies, now you need the Qualcomm Snapdragon LLVM OEM Toolchain which is used for building the firmware. | ||
| * In order to get the toolchain you need a Qualcomm account that has a license to it and you also need the Qualcomm Package Manager (QPM) | ||
| * Which you can download from Qualcomm's developer site anyway. | ||
| * Also, the reason why Python 2.7 was installed in the previous command is because the build scripts used for the firmware are coded in Python 2.7 so you must use that version to execute them. | ||
| * Make sure that if you enter "python" in the terminal, it calls Python 2.7 instead of Python 3.10. | ||
| * Now after installing the Snapdragon LLVM OEM Toolchain, you have to copy it to the following folder. | ||
|
|
||
| /pkg/qct/software/llvm/release/arm/3.9.2/ | ||
| * Since the path doesn't exist, you may make all the folders and set the correct permissions as they'll be created with the root user since the folders are supposed to go in the root filesystem of your Linux installation. | ||
| * Now after you've got everything you need installed and where it is supposed to be in, let's get to building the bootloader itself. | ||
| * In order to build it, you must execute the commands below. | ||
|
|
||
| # Setup build environment variables for building the XBL (eXtensible Bootloader) | ||
| bash boot_images/edksetup.sh | ||
| # Build the bootloader | ||
| python2.7 boot_images/QcomPkg/buildit.py -t Sdm660Pkg --variant LA -r DEBUG -c -Wno-error | ||
| **Congratulations**, you have successfully built the bootloader for the Qualcomm Snapdragon 660 *(that is, if you built it successfully)*, if you weren't able to build it successfully or you found an issue you can't fix, you may report them in the issues tab of this repository and I'll see if we can fix it, I should also warn you to **NOT** install this because of the OEM's TrustZone in your SDM660 device might not boot your custom build of XBL so you must build your own TrustZone as well. | ||
|
|
||
| How do I build everything? | ||
| ================== | ||
| Well, for now you may only build bootloader, I will be adding a build script that can build all of the source soon. | ||
|
|
||
| Where did you find this source? | ||
| ================== | ||
| I initially found it by doing some research about the internal strings and version strings I kept seeing in the firmware of my Xiaomi Redmi Note 7 (codenamed "lavender") and I stumbled upon a custom hosted GitLab in a Chinese site called "Mingwork", I check it out and it was Snapdragon 660 firmware, along with some more goodies, Mingwork seems to be a company that offers software development tools and solutions such as their custom hosted GitLab server which you can use just fine if you're in china, if you're not, good luck downloading anything from there. | ||
|
|
||
| What were your plans with this source? | ||
| ================== | ||
| Well my plans were to keep it a secret and use it to develop custom firmware for the Xiaomi Redmi Note 7 but I figured out I couldn't do this myself alone so I just made the repository public a while ago, I wanted to make my Redmi Note 7 do things that Xiaomi never meant it to, like booting an OS such as a Linux distribution (or distro for short) or Windows 10/11 for ARM64, all of this because of a single joke... *What happens if I were to compile Gentoo in my phone?* |
