On the Wiki-page for the Linksys WRT54GL v1.1 (http://www.dd-wrt.com/wiki/index.php/Supported_Devices#Linksys) is said "Requires Mini Build for first flash!". Does this mean that I can put a full version after the first flash?

Yup. There are some people that claim that flashing mini first isn't needed with newer GL's...
Better safe than sorry, so flash mini first and then which ever build has your fancy.
Don't forget to do the 30 seconds reset before and after every flash procedure! _________________ WRT54GL v1.1 @ 216MHz

I have brick my WRT54GL V1.1 with flash EON EN29LV320B (I suppose it's the same with MX29LV320B)and I have try JTAG and an CFE posted here,but the flash is not recognized.
So,first I have saved my cfe.bin
Tjtag -backup:cfe /fc:29
and put it back,same problem.After that I was doing this:
and now it's stoping at 3% adress 1fc02000 every time I am trying to flash it.What to do?And where I can find cfe.bin for this?It is corect to use /fc:29 in command line?

I just flashed my version 1.1 gl for the first time and it will work with the 23 sp 2 generic. But if you don't feel comfortable use the mini first. The 1.0 as I have read still must be done with the mini first.
Note: I tried Microsoft's TFTP several times first. It could upload the firmware just fine, but it wouldn't work properly afterwards. The Linksys utility worked right away.
5. Wait until the orange LED comes on.
After that, do what you want.
So basically the procedure is the same as before except (A) you're shorting pin 16 to ground, (B) you're keeping it shorted for a few extra seconds after the power is plugged in, (C) you're using Linksys TFTP.

Well, I finally got around to giving jtag a go - had 2 dead routers laying around here for ages.
Got one going.
Symptom - All lights on, power light flashing, no ping.
Do the pin short thing and it responds to pings but no TFTP comms, no menu from web browser. Power off and on again and all lights come back on, power light flashing.
Solution -
Build a jtag.
Sounds scary? C'mon, all you need to know how to do is solder.
You need a DB25 male connetor with solder pins, four 100 ohm resistors, and some wires.
I soldered mine straight to the cct brd of the router knowing I would be disconnecting them again if I got it going.
Install the driver on the computer, plug the cable in, get a DOS prompt and run the program
wrt54g -erase:nvram
All fixed. Browser came up, loaded correct firmware (paying attention to correct reset procedures for flashing) and all is sweet again.
I have been told it's not such a good idea to short the pins on the flash chip - certainly from my experience I can relate to that.
Now I know how easy Jtag is, I'll never need to again I reckon. _________________ More than 10 WRT54G/GL with a mix

Debricking a WRT54GL v1.1 s/n CL7C with the EON EN29LV320B flash chip.
You can use the "pin short" trick to get it to debrick, but with some changes:
1. Put your network card into 10Mb half-duplex mode with an IP 192.168.1.2. And plug into your router, of course.
2. With the router power unplugged, short pin 16 to ground (to the antenna block).
3. After plugging in the power, keep the pin shorted until the LAN lights go out (except the one you're plugged into, of course).
4. Use the Linksys TFTP utility to update to stock firmware. It's available at ftp://ftp.linksys.com/pub/network/tftp.exe
5. Wait until the orange LED comes on.
This has worked perfectly with my WRT54GLv1.1 sn:CL7B which features the same flash chip. I had it stuck in the bootloader without boot_wait, flashing power led indefinitely while all LAN leds were constantly on. Now happily running OpenWRT 10.3
