says deleted file @lytr
I can flash firmware. I just not sure what to flash. I need to make initramfs that is acceptable to the router. See my other thread here if you can assist
link updated
@lytr if you can just run me through how to select the correct ELF from the binwalk that would be great.
How do you know which ELF?
How do you know the start and end of the file? Ie how to dump it out
Thanks
EDIT: Nvm I found it. Looks like I can just patch out this PW check
Updated one more time
I decompiled a DTS file from the appended dtb in the stock kernel image found in partition "hlos"
Now I will attempt to build OpenWrt with this and flash the initrams to see if that will boot.
Any advice to get this right first time?
Thanks!
You can check support for ZyXEL NBG7815 (Armor G5) and QNAP QHora-301w. Also uses eMMC flash memory.
Do you have uboot access?
I dont have uboot access and dont think its possible. I patched out the password check in the uboot elf and wrote it to emmc then got this error.

This seems to be coming from the primary bootloader (uboot is secondary). Maybe a checksum or uboot elf is signed??
I have a hack that allows me to flash firmware without opening the device, so hopefully that is enough.
@robimarko how do I format this DTS I decompiled for the openwrt build? I dont have root access on the device, only have access to the filesystem. Trying to make an initial initrams image
For QNAP QHora-301w, the u-boot-env partition is on 8MB NOR flash.
Initramfs is loaded into RAM on startup, so you probably need access to uboot.
No the boot env partition is definitely here on the emmc. Its here:
UserData.BIN14 24610 25121 512 0:APPSBLENV
In my dump, at 0xC04400
Could I possibly patch this to try tftp on each boot
You cant use it directly, its just to get the relevant info
which parts are bare minimum required to boot?
Basically just UART and its pinctrl
Uboot now fails on the cmd "bootm" with this
Not allowed command, use bootipq.resetting ...
Thanks. I will get to that tomorrow. Regarding uboot. I tried to patch some bytes in uboot and then the device failed to boot uboot entirely, just because 1 byte changed. Do you think this is due to a checksum or is uboot signed and the device cant load anything else?
Secure boot is probably enabled
