Hello! I don't have a root password like you, have you solved it?

Anyone checked the new WiFi 7 router ( SBE1V1K) from spectrum?
Device details:
https://device.report/m/79ebc4a76a3f9db4a64dd8d985ab373a6e08484aecc50bc6f6382a0f427c5e2e.pdf

It’s using Qualcomm.

I just walked through opening my router and logged in via serial console. The hash values for contents of both mmcblk0p15 and mmcblk0p16 are the same - I am assuming this is to store a running version and a backup version. My device has never been connected / updated, so this would make sense for them to be the same:

U-Boot 1.3.3, Linux version 4.4.60
QC_IMAGE_VERSION_STRING=BOOT.BF.3.3.1-00163
U-Boot Partition(s) Hash: d75be109e242ee8923cb45f1cb082f83

This hash is the same as the backup U-boot reported by iv7777 on their device.

Is it safe to add this as an optional hash in the previously linked open.sh file and boot over TFTP or should I follow some other process (e.g. write directly to the active u-boot partition?) Thanks!

@iv7777 Thank you , just want make sure if my device

root@SAX1V1K:/tmp# cat /dev/mmcblk0p16 | md5sum | cut -d' ' -f1
7bc2f7766b270ea120495334cd1e5c56
root@SAX1V1K:/tmp# cat /dev/mmcblk0p15 | md5sum | cut -d' ' -f1
85ae38d2a62b124f431ba5baba6b42ad

then need to

dd if=/dev/mmcblk0p15 of=/dev/mmcblk0p16

?

              ;;
          esac

which is hackable U-Boot version 1.5.1

p16 contains v1.5.0, not hacked.

1st: verify that you are actually booting 1.5.1 (p15) !!!
check the log during booting.

2nd: then copy p15 to p16:

dd if=/dev/mmcblk0p15 of=/dev/mmcblk0p16

3rd) then run this: https://github.com/Lanchon/openwrt-sax1v1k

hell no, it is not safe!

the code will poke random bytes into the bootloader program on ram. it will NOT disable secure boot. and if you alter anything else, then you are bricked. in any case, you are guaranteed either a fail or a brick.

i suggest you start by running this and posting the output here.

also post the boot log up to the command prompt.

1- Bootlog can be downloaded here

2- For dumping U-Boot partition, what is the most appropriate command?

3- Might it make sense for me to connect this router to the internet and pull an update in the hope of receiving firmware updates similar to previous posters? This device has never been connected to the internet

4- Script Output:

root@SAX1V1K:~# ./configure-uboot.sh
