After few evenings of trying myself I gave up and hope can get some indication from the group. Here is data which I trust shall be collected:

My router WRT54GL version 1.0 (serial number CL7A0EB06978)
it was loaded and working with DD-WRT v24-sp2 (07/22/09) for approx 2 years.

I tried to get back to original linksys firmware from above DDWRT.

I searched right version and procedure on forum. I hope I did correct reaserch and found 2 step process to install vx... software and then I was planning to load WRT54GSv7_v7.50.2_fw.bin.

Something failed when I tried to load firmware: vxworksrevert-GSv7-v3.bin
Upload process seemed ok – but most likely I didn't wait enough time after restart. I also realized while upload there were other devices connected through other switch ports on back. I found it could be reasons why I failed.

I spent 3 evenings reading different threads on forum and didn't success to get ping to unit.

My current status:
a. I'm connected to router via one cable (I checked different cables). Network adopter is working. I used 3 different power suppliles (have 3 WRT54GL's) – with all PSU same results.
b. virus protection disabled on laptop, firewall disabled on laptop, wifi card disabled on laptop
c. laptop with windows 7 connected to router via tested cable to port 1 (but tried other 3 ports as well)
d. laptop network card is set to 192.168.1.9 (I also tried with previous IP address since I wasn't sure if firmware upload changed IP address. Before it was 192.168.100.113 – I tried ping this last known IP – but also no success. Same result on both. I tried IP address scanner – browsing in both ranges and found nothing via this tool (Advanced_IP_Scanner_2.5.3784)
e. ping -t 192.168.1.1 gives response „transmission failed. General error”, there is no any ttl response
f. there was no ttl= response, so I did hard reset again. I checked default ip address of DDWRT for WRT54GL – and it is 192.168.1.1. My network settings are correct (as above IP is set to 192.168.1.9 with 255.255.255.0 and 192.168.1.1 gateway, I made needed changes when trying other IP address – mentioned in point d.)
g. starting continuos ping doesnt give any result, no TTL responses. I tried power cycle. No differance in ping response.
LED's: power led is constantly blinking, led for port 2 and 4 are lit constantly sometimes all 4 port leds are lit. I noticed this changes depending if I do restart with or without ethernet cable connected. There was no reaction on WiFi led at all, there was no reaction on DMZ led at all (except when during 30/30/30 they blink for a milisecond when connecting power to router)
h. no ping responses at all during above process
i.I did hard reset 30/30/30 and was wathing ping, no reaction from router

I also was trying this command: arp -s 192.168.1.1 aa-bb-cc-dd-ee-ff (no success) https://wiki.dd-wrt.com/wiki/index.php/Recover_from_a_Bad_Flash
I was trying method with works.bin https://lancelhoff.com/how-to-fix-a-bricked-linksys-router/
I was carefully reading advices from peacock https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=51486
I was trying to get unit into „management mode” (found on one of above „recover from bad flash „thread)

Most likely I need to go into the more „heavy” router recovery with jtag

Although I'd like to ask someone more experienced to confim there is no other option or maybe you spotted something I missed while trying to recover it.

Any advice highly appriciated.

regards,
D.

Hello JWH7,

Damn. Means I did wrong search at beginning. I must have been reading thread about different WRT54GL model

Regarding thread you cited

https://wiki.dd-wrt.com/wiki/index.php/Linksys_WRT54GL#TFTP_Recovery

I've been reading it many times last days.

When I go to TFTP Recovery place in point 2.4 it has link to another post I read probably couple of times as well

https://wiki.dd-wrt.com/wiki/index.php/Recover_from_a_Bad_Flash

but all of them have one common prerequisite - to be able to Ping router.

As I tried to describe in my first post - I was not able to get ping to work when going step by step / different methodes.

The only one thing I didn't try is the command (mtd erase linux)

Thus my focus last two days was to get ping work. I didn't succeed and that why I wrote this post.

My understanding is if ping doesn't work - I have to go to more complicated method (unless I find way to get ping communication)

BR, Daniel

Hello,

I know I found incorrect instructions now. Thank you for confirming.

Not without guilt - but working on it few hours without glass of red wine would be hard.

I'll try again before going into jtag. Maybe your tequila method will work

Reason I wanted to change to OEM is I installed at home few smart home devices. I have 2 more WRT54GL's with OEM firmware and all works fine. Specifically problem was with WPA-2 authentication on DDWRT.

I read many posts and couldn't make it to work. After few tries I thought the simplest is to go back to OEM (which work on other two units)...

And few bottles of wine later am here

Regards, D.
