FAQ - Direct EMMC connect in pictures! Please stop ask again "HOW CONNECT" FAQ - DIRECT EMMC connect in pictures!! DONT ASK MORE! HERE SAMPLE OF CONNECTION TO PCB. http://imageshack.us/a/img809/9140/0x9n.png ===============FAQ============================== Q - If i not have Adapter can i connect to EMMC direct on boart? A - YES. But need use 2 external power. ================================================== Q - Why i need use double voltage? A - VCC - power of NAND memory inside eMMC (can be 2.8 - 3.3V) VCCQ - power of internal emmc controller. (can be 1.8 - 2.8V) (need setup vccq in sw same with real voltage) ================================================== Q - Do i need 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 solution for update internal emmc firmware. May be ... who know. ================================================== Q - Can i repair Suddenly dead phones. A - Yes. If something was erased in EMMC CHIP. ================================================== Q - Can i repair boot on phone with disable JTAG? A - Yes you can. (N7100,I9300 boot inside ROM2, after write ROM2 phones back to work) ================================================== Q - Can i repair dead phones I9082, i9105, S6810P with disabled JTAG, after touch ROM2. A -YES you can. Just need 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 byself EMMC pinout. A - Yes you can most of emmc have same pinouts. Need desolder EMMC and find where 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. HERE list of EMMC based samsung: ================================================== Q - Known Error and Problems: Correct data: ------------------------------------------------------------------Wrong log: --------------------------------------------------------WHAT TO DO: My log Loading eMMC Addon Firmware...

dear now I can tell you sure this an clear answer and really all question y answerd dear 100 % |
USE VERY SIMPLE BLANG SIR For eMMC direct writting need two type supply 1. 1.8 volt 2. 3.3 volt AND EASY JTAG BOX |
Please picture at the top, in best quality. Don't see names of IC. |
everbody GND connection is very important. please make very hard ( mean very thick) solder GND. |
Fopr everybody who wants adapter Adapter photo http://www.multi-com.pl/multicom/pim...apter_400A.jpg Ready set with I9000 with demaged JTAG pads to repair via EMMC Tool http://www.multi-com.pl/multicom/pim...apter_400B.jpg |
@blang Thanks for all the Info. Just had one Question, The IC In the Interface is BA33C18FP? Cant make out, as it is not Clear. To Build one, as it may take time for the Original to reach here. Br GURUGSM |
i will atach full shematic later. |

BA33C18FP/HFP Features : 1) 3.3V/1A, 1.8V/1A 2) Output voltage accuracy: +/-2% 3) PNP output and LDO voltage type 4) Built-in output current limit circuit protects the IC from destruction by short 5) Built-in temperature protection circuit protects the IC from thermal destruction by overload state 6) TO252-5 package, HRP-5 package http://vungoc-bacninh.vn/download/Pi...3X%20POWER.png |
Plz is there any other pnp ic like BA33C18FP/HFP cause i cant find it |
can add new Easy-Jtag box??? I waiting .....and buy one |
http://i1296.photobucket.com/albums/...ps37605048.jpg output 1.8V and 3.3V to pinout. No need any adaptor. |
you can make a little schematic? |
