TL-WA850re v2 - Too big uncompressed stream LZMA ERROR 1

Hi, I tried to recover a TL-WA850re v2 repeater, unfortunately it did not work
I've tried with OpenWRT, original and stripped firmware.

If someone can help
Thank you

Use the sysupgrade build to flash directly like this.

Of course you have to have the serial port working first. Copy "tpl" to the clipboard then when "Autobooting in X seconds" appears, hit ctrl-V to paste it out.

Yes But would this only work if I could boot from the OpenWRT correct ?

I already retired the device, I could not recover!
I should not have installed OpenWRT :neutral_face:

I have been able to restore it :smiley:, but with firmware openwrt 18.06.5 sysupgrade.
Note: Full restoration guide (TP-Link WA850RE v2.0 Bricked).

tftpboot 0x80060000 firm.bin

cp.b 0x80060000 0x9f020000 0x380004
bootm 0x9f020000

Note: According to printenv, setting ip eth pc to 192.168.1.10
Note: Rename firmware file to firm.bin for easy use.
Note: File size of openwrt 18.06.5 sysupgrade 3670020 bytes (0x380004 in hexadecimal)
