msm8916-mainline / qtestsign Goto Github PK

I tryed to sign the sbl1.mbn,emmc_aboot.mbn (for msm8974) use this tool,but it showed this

Hi,

I know this qtestsign is not made for other/newer SOCs. I still wanna try this out with a minor branded sdm636 phone and found something strange. please take a look if you are willing to support other SOCs.

the weird happened in Program Headers, looks like the load address altered. and the supposed hash/cert section is absent/stripped in the output mbn file. the source mbn and the output mbn file is zipped.
