Member: 1869842 Status: Offline Sonork: 100.1625473 Thanks Meter: 186 | My advice for you : Software: Flash a boot file Hardware: 1- clean your motherboard with ultrasonic cleaner with tiner liquid 2- check input and output voltage for power ic (pmic) same as schematic 3-resolder power ic(pmic) using past not flux not a long duration cause past can not stand longer time like the flux and of course you know the difference between this two 4-use z3x jtage to repaire emmc 5-replace emmc |
