TomatoUSB

Hello all,

my router is Linksys e4200 and I downloaded and upgraded firmware to:
Tomato v1.28.9052 MIPSR2-beta23 K26 Std
The problem is, that since that time, I'm not able to connect to the internet, but what's the bigger issue, I'm unable to remove this firmware from my router.
When I try to upgrade following error appear:
"File contains an invalid header"
I found this in the source code: twtomato.googlecode.com/svn/trunk/source/117/src/router/rc/mtd.c

Then I'm unable to connect to the router for about 3 hours (it seems it is in restarting cycle).

I'm lost..

Could you please help me revert my router to the basic firmware from linksys or any functional one?

Thanks a lot
kafe

ok, I found the solution..

1) checked the piece of code under the link I've sent in previous post

    error = "File contains an invalid header";

    if (safe_fread(&sig, 1, sizeof(sig), f) != sizeof(sig)) {
        goto ERROR;
    }
    switch (sig) {
    case 0x47343557: // W54G    G, GL
    case 0x53343557: // W54S    GS
    case 0x73343557: // W54s    GS v4
    case 0x55343557: // W54U    SL
    case 0x31345257: // WR41    WRH54G
#if TOMATO_N
    case 0x42435745: // EWCB    WRT300N v1
//    case 0x32435745: // EWC2    WRT300N?
    case 0x3035314E: // N150    WRT150N

2) opened firmware bin file in hexeditor (I used wxHexEditor) and changed first four characters from 4200 to W54G (57 35 34 47)

3) upgraded successfully.

hi Kafe,
I had same issue like yours yesterday(1/22), and follow your instruction fixed it. But there is a difference is:

we need to use official firmware comes from CISCO, and the firmware name is —> FW_E4200_1.0.03.014_US_20110920_code.bin

Thanks!

Toastman has builds specific to the E4200: http://www.4shared.com/dir/v1BuINP3/Toastman_Builds.html#dir=145397891

@kafe

You're lucky enough that your router is even accessible.

You should really read before flashing random things to your router, and furthermore before hex editing files to force things through…

As CTXSi noted, that's where the proper files for the E4200 are. PS. All you had to do was search the forum for E4200 …
