Basic Knowledge...!
Q - If I don't have Adapter can I connect to EMMC direct on board?
A - YES. But need use 2 external power.
==================================================
Q - Why I need to use double voltage?
A - VCC - power of NAND memory inside eMMC (can be 2.8 - 3.3V)
VCCQ - the power of the internal eMMC controller. (can be 1.8 - 2.8V) (need setup VCCQ in SW same with real voltage)
==================================================
Q - Do I need to connect anything else to phone PCB?
A - NO. NO NEED CONNECT BATTERY OR USB CABLE TO PCB.
NEED ONLY 6 WIRES: GND, CLK, CMD, DAT0, VCC, VCCQ
==================================================
Q - Can I repair EMMC CHIP (suddenly dead phones)
A - NO. AT THIS moment you cant repair EMMC. But we work on the solution to update internal emmc firmware. Maybe ... who knows.
==================================================
Q - Can I repair Suddenly dead phones.
A - Yes. If something was erased in EMMC CHIP.
==================================================
Q - Can I repair boot on phone with disabling JTAG?
A - Yes you can. (N7100, I9300 boot inside ROM2, after writing ROM2 phones back to work)
==================================================
Q - Can I repair dead phones I9082, i9105, S6810P with disabled JTAG, aftertouch ROM2.
A: YES you can. Just need to write ROM2 via EMMC direct connection.
==================================================
Q - Where I can take EMMC DIRECT connection pinout on BOARD?
A - Tested EMMC direct connect pinout we uploading to EMMC pinout under phone folder name on support.
==================================================
Q - How can I find myself EMMC pinout.
A - Yes you can most of emmc have the same pinouts. Need desolder EMMC and find where to go 5 pins. CMD,CLK, DAT0, VCC,VCCQ
==================================================
Q - What phones supported by EMMC Tool.
A - Supported any phones for READ/WRITE based on known EMMC. At this moment we support most of known EMMC.
