\"\"<\/a>Metoda ISP (In-System-Programming)<\/strong>, kter\u00e1 je tak\u00e9 zn\u00e1m\u00e1 pod n\u00e1zvem direct eMMC<\/strong> spo\u010d\u00edv\u00e1 ve vyu\u017eit\u00ed mo\u017enosti p\u0159\u00edm\u00e9 komunikace s pam\u011b\u0165ov\u00fdm eMMC chipem prost\u0159ednictv\u00edm vhodn\u00e9ho rozhran\u00ed. A to bez nutnosti vyjmut\u00ed pam\u011b\u0165ov\u00e9ho chipu<\/strong> ze za\u0159\u00edzen\u00ed. Podobnost s metodou JTAG je v\u0161ak pouze zd\u00e1nliv\u00e1 – ISP spo\u010d\u00edv\u00e1 v komunikac\u00ed s eMMC na p\u0159\u00edmo<\/strong>, kde\u017eto JTAG pot\u0159ebuje je\u0161t\u011b procesor.<\/p>\n

Pro metodu ISP se pou\u017e\u00edvaj\u00ed tyto piny:<\/p>\n

– DAT0
\n– CMD
\n– CLK
\n– VCC (a\u017e 3.3V)
\n– VCQ (1.8V)
\n– GND<\/p>\n

Tyto piny je t\u0159eba lokalizovat na z\u00e1kladn\u00ed desce p\u0159edm\u011btn\u00e9ho mobiln\u00edho termin\u00e1lu a propojit je s vhodn\u00fdm rozhran\u00edm. Vy\u010dten\u00ed pam\u011bti samotn\u00e9 je pak provedeno prost\u0159ednictv\u00edm vhodn\u00e9ho rozhran\u00ed (Z3X, UFi, Riff…)<\/p>\n

Tato metoda je vhodn\u00e1 pro forenzn\u00ed \u00fa\u010dely, z\u00edsk\u00e1v\u00e1n\u00ed dat z rozbit\u00fdch nebo vytopen\u00fdch mobiln\u00edch telefon\u016f. D\u00e1le je mo\u017en\u00e9 j\u00ed vyu\u017e\u00edt pro prolomen\u00ed zabezpe\u010den\u00ed (PIN, gesto…) nebo i odstran\u011bn\u00ed FRP.<\/p>\n
