Ah....ok. MTD partitions are labeled differently in stock firmware vs DD-WRT.
Run same command, but replace kernel1 with linux and replace kernel2 with linux2

If that doesn't work you may have to add /tmp/ before the file name. I can't remember which way for DD-WRT.
mtd -e linux2 -r write /tmp/venom.img linux2

Did it
By the way, I update only one partition,
I couldn't access the second one after it reboot.

Thanks! I'm sure your thread will benefit others.

Once you're back to the Venom GUI you should be able to manually upload & flash the stock Linksys firmware from the Router Administration section. This would overwrite the opposite partition with the Venom firmware as well.

Linksys WRT32X Support - Firmware Download
https://www.linksys.com/us//support-product/?pid=01t34000004FeJ0AAK

If for some reason that doesn't work, you simply need to SCP the venom.img to the /tmp folder again. Then SSH in and run:
mtd -e kernel1 -r write /tmp/venom.img kernel1
or
mtd -e kernel2 -r write /tmp/venom.img kernel2

* Use the opposite of the partition you first flashed.
** Remember: once on stock firmware, MTD5 & MTD7 are named kernel1 & kernel2 (respectively)
** On DD-WRT MTD5 & MTD7 are named linux & linux2 (respectively)

I can;t connect winSCP or shh. I get that the password is wrong.
I did flash again the stock firmware through GUI.
Hope it did it in both partitions.

Anytime you change firmware type or erase a partition the SSH Key changes. PuTTY and WinSCP should give a warning followed by an 'update SSH Key prompt' and allow you to continue.

Everytime you flash firmware from the User Interface (Linksys, DD-WRT, OpenWrt, etc...) it always goes to the opposite, inactive partition.
If you were able to automatically or manually upload & upgrade from Linksys Venom GUI without errors - you now have Linksys firmware on both partitions.

The easiest way to see what partition is currently in use is with Telnet / SSH:

Linksys Venom & OpenWrt
fw_printenv boot_part
* SSH Port 22 is enabled by default.

DD-WRT
ubootenv get boot_part
* SSH Port 22 is disabled by default in DD-WRT. Unless enabled, you must use Telnet port 23

Yes indeed. Thank you to all who contributed to this solution. I was playing around with different firmwares and wound up with both partitions not having stock Linksys firmware. I thought I was screwed. I followed your instructions and was able to flash back to Linksys, and then back to DD-WRT. For me, the grass wasn't greener on the other side. Thanks again! Cool

I was looking over your mtd instructions and had a question. Is it required to do a reboot (-r) on the first instance of mtd? This would save a boot and another wget of the image wouldn't it?

mtd -e linux write /tmp/linksysfw.img linux

mtd -e linux2 -r write /tmp/linksysfw.img linux2


It could be I am not fully understanding!

It's not necessary to mtd write both partitions. With the stock firmware back on one partition you have your choice of upgrading the stock Venom image or upgrading to DD-WRT.
Both of which will overwrite the alternate partition.

That makes more sense - thanks for clarifying. I read earlier where it was entered twice.
