It certainly looks identical for a 16M flash and a 32M flash.
@jgdempsey What is the model number on the winbond chip?
Yes,except that it only has 4 antennas, not 6, but I think the missing two are the 3G antennas.
It's a 25Q128FVSG, which is a 128M bit, so it's 16M bytes..
Cool beans...you got it.
OK, now that we have figured out that it is in fact a ZBT-WG3526 16M, the next step would be to get the serial up and running and see what it spits out.
BTW: When updating from OpenWrt to LEDE 17.01.4: Did you check the "keep settings" checkbox or did you uncheck it?
Re the "keep settings" question.. I don't recall.. I may not have unchecked it.
I have most of the pieces to connect to the serial port, but I'll have to shop for a DB9 connector to connect to the usb - serial cable..
This is a good one to have on hand...
VCP drivers for the CP210x ...

Thanks for pointing this out.. I didn't realize that I would need a level converter (TTL to RS232). You saved me from frying something..
Would this do the job? https://www.kijiji.ca/v-networking-cables-and-connectors/ottawa/usb-to-rs232-ttl-uart-pl2303hx-usb-to-com-module-cable/1033768870 (something I can by locally tomorrow)
Or Maybe this one is better: https://www.buyapi.ca/product/usb-to-ttl-serial-cable-debug-console-cable-for-raspberry-pi/ because it will work with Windows 10 (not that I need it now, but may later)
Looks like both would work...don't use the red wire (VCC - 5.5v).
OK.. I've got a USB > TTL cable, and got the header installed on the board. I've played around with the speeds, but I'm not getting anything back from the unit besides a few dots.. If I send a "reset port" from the terminal program, I get a dot back from the router (and RX flashes)..
I've also tried monitoring it while attempting a recovery but nothing is output to the terminal..
You might take a look through the LEDE documentation before continuing...

I have the same router and with connected serial port it did not boot - I had to turn on the router (without port connected), then wait a few seconds and then connect the port. (but I had a combined converter that was a problem)
device has a web based bootloader on 192.168.1.1. press reset button, aplly power holding reset button pressed until lan led from connected lan port begins to come up.
bad news, only chinese laguage based. but on the first page, hit the big button in the middle, a popup will allow you to pick up a file from your hdd. select the firmware you want to flash, press ok button in the next window and wait. device will reboot from it's own and: you're done with recovering...
question: anbody able to get an english webgui for the bootloader on it?
( allnet wrt1200ac, same board as jgdempsey )
that's correct, zbt routers normally has this never-die-uboot feature that means you don't really need access its serial ports
Hi,
I have a 16M ZBT WG3526. Just upgraded ver 18.06.5 to 19.07.1. So far no problems, & I must say that ver 18.06.5 really cracks! Fastest I have ever seen this router run.
I have only ever used the update in the Luci interface. I originally updated from Lede to OpenWRT again with no issues.
One suggestion is to not use your old configuration when one updates between major versions. Save the configuration you used as a guide (by printing each page), but enter it by hand. Bit more work, but much better in my estimation.
Good Luck!
