You never said that renaming the file didn't work. Also, you never mentioned in the first post that you renamed the file. In the future, please inform us, instead of getting mad.
LOL, there were answers
You should be able to TFTP and it does not look for a regional code (the error 18005).
2 (a response I wrote regarding the SAME MODEL-different version!!!):
We're not psychic...we don't even know what language you're translating form.
Thank you for all these useful and enefic instructions for me
very funny it's very easy and it shows a little intelligence to make fun of it.....
I'm not making fun. I can't guess that you'll get angry because you have to read posts (in a foreign language) on error 18005.
I was making note - that you posted a link to a translator, but never said what language to translate to.
I am willing to speak in your native language, if its the cause of your anger.
Did you succeed in TFTPing the file, and bypassing the 18005 error?
¿Tuvo éxito en TFTPing el archivo y omitió el error 18005?
Avez-vous réussi à TFTPing le fichier et à contourner l’erreur 18005?
您是否成功完成TFTP文件并绕过18005错误？
Reading in a foreign language is not what makes me angry... reread posts I have already read before posting either.
It is not the content that bothers me (because I have succeeded thanks to you and your tracks) but the form that is really not pleasant and more than dismissive.
As a result, everything that follows behind in your answers looks more like an attack than a help.
Anyway, I managed to install it.
Now I need help to change the basic ip address from 192.168.1.1.1 to 192.168.0.1.
I've tried many times but it makes me a rollerback
Thank you for your help
OK...You have 4 options...I suggest them in this order:
/etc/init.d/network reload(This information was also locatable by searching the community.)
Ok but "Apply Unchecked" crash my router and I'm forced to do a reset it's better if I pass part /etc /init.d/network?
Describe what you mean by "crash"?
Unless you misconfigured your LAN, hitting "Apply Unchecked" shouldn't cause such an issue.
That's your choice:
Edit the option ipaddr LAN section in /etc/config/network
Save
Then run /etc/init.d/network reload
MAKE SURE YOU CHANGE YOUR IP, OR GET A NEW LEASE!!!
thanks for your help I will test this, but nano is not installed it is what is the editor put on openwrt?
Do you have a complete tutorial on the configuration of openwrt but in..... French 
because I have a lot of gaps.
If it is truly "crashing" your router, then capturing the logs, perhaps by ssh-ing into the box and running logread so they remain on your terminal screen for easy copying, would help determine if there is a bug.
When making IP address changes of this sort, on OpenWrt or otherwise, I always make sure I have connectivity to the device that will "survive" changes or errors. This can include, for example:
If I didn't have console access, I would:
For me, a separate management interface (on a VLAN, if possible) is among my first steps on any device, OpenWrt or otherwise.
vim - Vi IMproved
You can also install nano if you have enough space:
opkg update
opkg install nano
Oui!

Thank you but you are completely out of my field of expertise 
Good morning, everyone,
Thank you bcp for your help it works!
But I still have 2 3 questions
Thank you again for your help and answers
DHCP list will only show devices which used dhcp from the router. Those configured with a static IP will not be in the list. You can see the IP and MAC of everything that has connected to the router using arp.
If you are double-NATting (the WAN IP is a private one 192.168.1.X issued by the modem), you can access the modem by simply going from a LAN PC to 192.168.1.254. Anything outside of 192.168.0.X will be routed to the WAN port automatically.
If your modem is bridged (a public IP on the WAN) you can add a second IP to the WAN port and a route to it to access the modem's administration page.
Control such as having a list of allowed and disallowed websites is possible with OpenWrt, but takes more memory than your device has. Time based all or nothing rules like turning off the wifi or Internet access entirely at night is possible.
Thank you for the answer.
If I understand correctly I should have no problem accessing my box by typing 192.168.1.254 since it is on the LAN port.
Except it doesn't work. I have a following error: DNS_PROBE_FINISHED_NXDOMAIN
What is ARP? I'm not yet top of the line yet.
As a parental control I'm mainly looking for something like "this device can't connect to the internet from this time to that time or that day".
Is there an android APP to control a router from a phone?
This is an error on your part. Ensure that you're properly typing the IP address. For some reason, your client saw that entry as a bad domain name.
Try clicking this URL: http://192.168.1.254
Have you seen this section in the Firewall section of the LuCI web GUI?
Just browse to the router using your browser. You should see this page easily on a phone.
(Again, this infomration is included in the manual, and by searching the forums: Parental Control for time restrictions not working with "reject")
Thank you but I don't have that under my firewall menu. (unless I'm blind)
I think it's a mistake on my part but I can't find the solution because on the old firemware it was the dns that didn't work.
I can't be good at it.
Thank you but I don't understand any more I'm going to read what you gave me you never know.

S'il vous plaît, prenez un moment pour parcourir l'appareil vous-même.
It seems as if you're not willing to take time to simply browse the web page.
You may be...
And what about when when you actually CREATE A RULE!?!?!?!?!?!?
(Again this information is in the manual, and available by searching the forums.)
You asked what ARP is. I sent you a WIki entry (in French and English) - and the manual to use the arp command. The DHCP server in OpenWrt only knows the IPs it issued. As @mk24 said, to see all other IPs:
believe me that's what I do, but I'm not a pro and therefore what seems logical to you is not logical to me. I looked at the links you gave me but I didn't see all this.
Sorry again to bother you.
I won't bother you again.
Thank you. Thank you.
