Yes it's possible to build safeloader compatible fw as You might find it on 4pda.to . I've did other thing with MR1800X (MR70X twin device) .Scrap mdt3 (factory) partition ,Flash breed (model xunlei-timeplug) and restore factory mtd3 in breed .Now build openwrt and flash it in breed .All decribed on openrouter.info • Wyświetl temat - Mercusys MR1800X i MR70X wgranie breed + OpenWrt/Padavan .
Thanks! I'll try using the version provided by the 4pda user to test the wifi roaming capabilities. Also haven't heard about Breed, will look into the second solution as well.
