Bitsum does not support the Firmware Mod Kit, an open source project for technicians that is hosted at Google Code. The Google Code site can allow you to submit this problem report, and perhaps get feedback. I'm sorry to hear of your troubles.

У меня tp link 841nd c такой же проблемой - не работают обратно собранные прошивки, даже если в них ничего не менять, mod kit неверно собирает rootfs роутер думает что она или не того размера или полупустая, собирается из каталога /trunk/src/others/squashfs-3.3-lzma/squashfs3.3/squashfs-tool/mksquashfs - без ошибок, но размер roots меньше. Роутер удалось восстановить через serial на плате...
Не пойму как написать о проблеме авторам проекта, кто есть кто ? ))

пробовал с разными ключами размер подобрать, не стартует на роутере, приходится оживлять через консоль его )) как можно узнать как запакована оригинальная прошивка, с lzma ? размеры блоков ? словаря ? ...

Code: [Select]
