rNfxSmvhkaM.jpg3J0022GsGMA.jpg Пришел планшет PMP 7280C 3g Quad с проблемой зависания на включении, попытка сделать хардресет привела к зависанию на строке format. При проверке на флештуле выскочила проблема Error Nand Flash, после чтения получил кирпич. По usb определяется как Mediatek PreLoader USB VCOM. Предприняты попытки прошивкой 1.0.13 под флештул, приводят к error: ? (0x8)...
Подскажите куда копать, менять NAND или можно провести программный ремонт ?
