7621+7612+7603 变砖，拯救成功
本帖最后由 游弋 于 2024-3-9 22:28 编辑想刷wrt做聚合，结果变砖了。
具体硬件如下 7621at+7612en+7603ennanya 128 16m spiw25q128fvsig LAN/WAN LLLLW
刷了 r3g 的 breed,变砖。
有编程器，直接刷回之前也备份过的固件竟然还是无法正常启动。一直卡在 Starting kernel ...
复位键能进uboot。
抢救中......
中间编程器又尝试刷了 8820v2 和 小米4a 的固件，启动后都是1秒闪一下灯，重启。
没找到合适的wrt固件，也没找到可以用的breed。主要是也不知道刷哪个版本。希望各位路过的大神，指导小弟一下。
下面是ttl输出信息。一直卡 Starting kernel ... 重启

有编程器随便折腾，spi是真的不死，先擦除芯片，然后可以尝试刷入稍微旧点版本的breed，然后在breed下刷入系统 R3G是nand，你的是SPI，能启动才有鬼了 小小葫芦娃 发表于 2024-3-9 11:13

刷了wr1200js,别人的全量包没启动，
刷了breed-mt7621-pbr-m1.bin ttl有反应，复位键无效，
