Каждый раз когда я изменяю настройки и жму 
кнопку сохранить и перегрузить. При старте, 
железка входит в краш режим. Помогает 
только вытягивание из него питания и 
вставка назад. Пробывал прошивки 1967, 2054, 2041.

Без логов нельзя сказать абсолютно ничего. 
Увы у нас ни у кого нет RT-N12 в наличии.

Какие именно нужны логи и как их вытащить 
при краш режиме ?
Под краш режимом я имею ввиду приглашение 
mini web server который позволяет загружать 
прошивки. И при этом Wifi интерфейс отключен.

После передёргивания питания настройки 
новые?
reset to default не был забыт?

При такой симтоматике мог бы помочь лог 
консоли, плюс хорошо бы увидеть хоть один 
syslog при успешной загрузке.

После передёргивания питания настройки 
сохраяются такими как их выставил. Сброс в 
дэфолт делал не однократно. Как попасть в 
консоль и снять с него лог ? Это нужно 
делать в краш режиме или нет ?

Лог успешной загрузки

Консоль - это физический порт rs232, см. форум 
wl500g.info. Без вскрытия роутера увы не 
обойтись.

Различие в логе объясняется 
неисправленной багой в syslogd+uclibc. Разметка 
флеша стандартная, других идей о причине 
проблемы пока нет.

Может быть перед прoшивкой нужен какой-то 
инициализационный флэш как у dd-wrt ?

Нет, наша прошивка не изменяет CFE, именно 
поэтому шансов убить роутер при 
перепрошивке нет.

Просто вариант для N12 нами лично не 
тестировался, ввиду отсутствия железа.

Просто как-то странно что CFE активируется 
именно после сохранения настроек. А при 
обычной загрузке нет. Может быть как-то 
програмно можно обойти это ?
Посмотрите может быть при сохранении 
настроек они задевают каким-то образом CFE 
заставляя тем самым роутер думать что его 
перевели в краш режим.

Может быть стоит рассмотреть вариант, и 
внести изменение в алгоритм или место 
сохранения настроек.

К сожалению, исходных данных для анализа 
слишком мало, чтобы не гадать на кофейной 
гуще. Неизвестна даже версия CFE.
