Внутри чистый, следов воды и удара нет. BEST-ом шьется, в локал не входит ни при помощи read rpl ни после прошивки, в том числе и в COLD режиме. Фул сливается, тел. книжка в нем обнаруживается.

Для уверенности после прошивки прогрет, ситуация - те же яйца тока в профиль. Т.к. локала нет, симлоки не бекапятся, соответственно безболезненно не стереть. АКБ другую пробовал. Есть ли еще какието варианты или только PRL?
