SUPPORT FOR TP-LINK TL-WR940N Ver 5.0


#14

i try to compile myself a firmware.. and generate 3 files squashfs factory, one .bin and other two -eu and -us.... but all of them give me the 18005 error trying to update de firmwre using web interface


#15

Hi @mportela,
I try to prepare BR version of lede firmware. Can You test it?
This is latest LEDE snapshot.


#16

Try renaming the LEDE firmware file to a shorter name, such as factory.bin

Otherwise, try TFTP.


#17

Hi Thankyou!!! It works like a charm... and no need to rename to shorter filename... just upgrade in the tplink webupdate normal GUI.

What do you do to compile this that works ? Its some patch, or just build using the branch SNAPSHOT ?!?!? I try with release 17.01.4 ... and generates 3 files... when you use the SNAPSHOT you just go to menuconfig and select the TARGET etc and then make ? how you generate this factory-br.bin file ?!!?!? or just rename some of then ?!?!

Enjoy some command tests in ssh (no Luci in your firmware):

First i check BR version of stock image.
Firmware header have diffrent value of region code:
BR:
image
EU have 4555, US have 5553

I use hex editor to change this value in factory-eu.bin form 4555 to 4252 and use mktplinkfw tool from firmware-utils to check MD5 sum and again correct MD5 in hex editor.

Maybe someone add BR region code to mktplinkfw tool.


TP-Link MR200 firmware update
#20

Ok, i Will try this with my custom firmware...

Thank You again!!!


#21

If You have installed LEDE firmware just use sysupgrade image file.


#22

Ok i Will use this method (sysupgrade) to test my custom firmware and my app.
But i Will need later to prepare this factory bin as you did to flash hundred devices.
And for this, i will try your method:

Use hex editor to change this value in factory-eu.bin form 4555 to 4252 and use mktplinkfw tool from firmware-utils to check MD5 sum and again correct MD5 in hex editor.

Do you have some tips to do this, or some other link forum ?

Thx


#23

I prepare patch to make BR factory image:
Look here: https://github.com/heinzek/source/commit/4de3ccd42a31c02c9900fc97f40b89faaf34bda3
use command on your "source" directory:

wget https://github.com/heinzek/source/commit/4de3ccd42a31c02c9900fc97f40b89faaf34bda3.patch
patch -p1 < 4de3ccd42a31c02c9900fc97f40b89faaf34bda3.patch

#24

it works!

i sent an email to the author: Matthias Schiffer asking for it and confirm this fix, just minutes before you send the patch, was the same thing!!!

Thank you


#25

When i ask the author, he told me, to open a PR with the fix, do you will do that ?


#26

Ok i Will use this to test my custom firmware and my app.
But i Will need later to prepare this factory bin as you did to flash
hundred devices.

Thx


#27

Ok. i open PR: https://github.com/lede-project/source/pull/1564


#28

I have a same problem when I try to flash to LEDE from stock, my device is TL-WR940N (VN). @Heinz could you help me build another version support VN region?
Thanks


#29

hello @mportela. I have same router (TP LInk - WR 940N (BR) V5). In the box showed 256mb ram, but the tp-link support reply is have 32mb.

Pls, is possible confirm the detail. Is 32mb ram or 256mb ram?

Thanks


#30

@jucato, look for my commands from previous messages, "df -h" and "free -m", it looks 32 and not 256....


#31

HI @theday0314 i create a fix for implementing your REGION.

the fix is here for testing and waiting the previous PR to be merger by LEDE...

https://github.com/mportela/source/pull/3

I don't know how to send the image here in forum... but upload a VN version here for you if you can't compile it using my version:
https://expirebox.com/download/cb064d3dfbece11f8a37c2b9f2b54517.html


#32

and @theday0314 if have some problem, try renaming the LEDE firmware file to a shorter name, such as factory.bin before...


#33

thanks so much, this works fine :smiley:
