I found a uboot for ipq5018 qcom reference boards https://git.codelinaro.org/clo/qsdk/oss/boot/u-boot-2016 .Considering my router is quite similar to one of those boards so the uboot should workon EA9350 i think? Let me compile and try to chainload it from the stock uboot.(Btw I have never tried chainloading on qcom platform but i did try that on amlogic platform.)
