After changing my RAM-Chip from 32 MB to 64 MB on my TP-Link WR740, WA701 devcies I have exaktly the same situation like @zein-zc describes. There is only a low shinning green LED on LAN1 to see if you put PowerPlug into the devices. I did it like described in a Tutorial for WR841 devices. The ROM was changed before from 8 MB to 16 MB SPI you describe here and it ran under 32 MB RAM-Chip. Unfortunately now I have a few letter weights laying arround and it was clean soldered in a company for PCB-Stacking nearby. So I guess there was no mistake after soldering and didn't see any shortcuts or not good connected PINs etc... So I am bit unhappy about the non-working half-professional extend-try.

But back to this topic @zein-zc I guess you need to shortcut or unprotect UART-Mode somewhere like it was also necessary on EB802, EB803 and so on... there is usually unfortunately always a bit of a mess to bring devices back to life.

If you see no line's in CLI and did already change RX/TX Pin I am pretty sure your CPU did unfortunately die and there is no good economical way to repair it...

There are instruction by borodean in forum:

Scroll down to his post from Feb'19 and repeat his steps.
Successfully recovered mine wifi3 using his method.

I also need to solder an SPI flash as my NAND has too many faults :frowning: Do you really mean 4.7 Ohms or 4.7k Ohms? I thought that 4.7k Ohm might be more suitable?

958

I use as instructed on 4pda, here: Xiaomi mi wifi 3 support

Is it possible to update to 19.07.5?

960

Try X-Wrt, it uses latest stable newest OpenWrt code.

961

Anyone build openwrt 19.07 for this device ??

962

Yes. There are prebuilt:

Hi there,

Recently purchased this model.
I'm trying to compile openwrt from @romandas last post. First try.
Just want to confirm if i miss something on make menuconfig

*MT Ralink MIPS
*MT7620
*MI Router R3
*ramdisk
*squahfs
*Luci collection

Also, can i use the squashfs-sysupgrade to upgrade from x-wrt or should i flash it the same way?

Thanks in advance!

965

Hi,
I didn't compile that 21.02 OpenWrt, but I would follow compile instruction in later posts. Yes you can use squashfs-sysupgrade from xwrt and vice versa, but do not keep settings (remove checkbox) when uploading firmware.

Prebuilt 21.02.0-rc3 and rolling releases with archive

@romandas Will be possible to compile all the kmods and put in the link?

Then we could use all officials packages that depends on any kmod (that are a lot)

Working perfectly the rc4 after updating from rc3.

Thanks for your work.

968

Hello, it's not my repository. I do not compile it. You can write to the author and ask what kmods you want he included.

969

Anyone how I can flash OpenWRT if Padavan resides on the box ? Padavan doesn't accept the sysupgrade package and mtd won't permit to write to the partitions either ?

Will the only way be to enable TFTP via UART during bootload ?

Thanks.

First return to original stock firmware. Then install OpenWRT or XWRT using instructions from OpenWRT device page.
