QTESTSIGN.PY(1)

💖 NAME 💖

qtestsign.py — a lil tool that signs Qualcomm ELF firmware images with test keys 🫶

✨ DESCRIPTION ✨

okay so bestie, here's the vibe. you run it like this:

usage: qtestsign.py [-h] [-v {3,5,6,7}] [-o OUTPUT]

and then you gotta hand it a firmware type from this very specific roster, plus the elf file you wanna mess with:

{sbl1,mba,modem,prog,adsp,devcfg,tz,aboot,uefi,rpm,tz-app,wcnss,venus,wlanmdsp,gpu,hyp,cdsp,slpi,abl,ipa,cmnlib,shrm,aop,multi-image,multi-image-qti,qup,xbl-config,cpucp,aop-devcfg,xbl-ramdump,cdsp1,modem-dtb,cdsp-dtb,adsp-dtb,gpdsp0,gpdsp1,av1,kernel}

elf

so what does it actually do? it "signs" Qualcomm firmware using a dummy certificate chain 👑

⚠️ okay pause. read this. for real. ⚠️ the image format is only partially implemented, and like… there is actually no signature generated. none. zero. nada. 😭 this only works on devices that have firmware secure boot disabled 💀 and the tea is: most Qualcomm devices out there in production have firmware secure boot permanently enabled, with no way to disable it. so if you flash modified firmware onto those, they will fail to boot. not a vibe. not the moment. 🚫

🎀 positional arguments 🎀

• {sbl1,mba,modem,prog,adsp,devcfg,tz,aboot,uefi,rpm,tz-app,wcnss,venus,wlanmdsp,gpu,hyp,cdsp,slpi,abl,ipa,cmnlib,shrm,aop,multi-image,multi-image-qti,qup,xbl-config,cpucp,aop-devcfg,xbl-ramdump,cdsp1,modem-dtb,cdsp-dtb,adsp-dtb,gpdsp0,gpdsp1,av1,kernel} — the firmware type, which is what sets the SW_ID 🦋
• elf — the ELF image you want to sign 💅

🌸 options 🌸

• -h, --help — pops up this help message and then dips out 👋
• -v, --version {3,5,6,7} — the MBN header version. you HAVE to set this correctly based on your target chipset, no guessing bestie. check the README for the deets 📖
• -o, --output OUTPUT — where the output file goes 🎯

and that's the whole page, bestie!! go forth and be careful 💖✨
