![]() This command spits out lot of output, but we are looking for something like this. You can get more complete view, how they are arranged by checking boot dmesg With the rest we can only guess for now, where they are placed. Surely at the zero offset starts “u-boot” partition, because this one contains bootloader, which is executed at first, when device is turned on. Let's look how many partitions are there and how long they cat /proc/mtd That means that these “partitions” doesn't contains any meta data about them, can overlap each other and also writing operations can overrun their boundaries. But in this case, we are not dealing with hard drive and real partitions, but with mtd and named memory offsets instead. You have to know how flash memory of your router looks like and which blocks can be rewritten without causing serious damage to device functionality.įlash memory is divided into parts like hard drive is partitioned in traditional computers. To safely brick your device, you have to perform some terrain reconnaissance. If your router has other bootloader, following procedure probably will not work.įor recovery you must have access to device serial console. This article is about unbricking routers with working bootloader, in this case a TP-Link TL-WR703N which is using U-Boot. If you have untouched a bootloader, unbricking process is really easy. But it may occur that things goes wrong and you will brick you router. Especially a firmware compiled by yourself. Flashing routers with custom firmware if fun.
