Hi, Anyone tried (and succeeded) in upgrading the Flash from 8M to 16M on TP-Link TL-WR902AC v3? Been trying for days following all the suggestions on the forum. The flash is recognized by original uboot (mtd0 dump), and it boots the 8M openwrt image fine. Didn't succeed in booting a custom image …

0x0 0x20000 boot 0x20000 0xf00000 firmware 0xfb0000 0x10000 config 0xfc0000 0x30000 factory I hope I did the hex calculations from my head correctly🙂

You need to build a custom image. Soldering UART might provide more details regarding to bootloop.
