EMMC Adapter for Riff BOX allows a very simple repair phones with blocked JTAG access (GT-i9300 / N7100 / N719 / N7102, etc.), repair phones with damaged JTAG points/pads (access to ROM2 by EMMC) or read/write EMMC applicable for the data recovery/analysis. Using the adapter you can perform format EMMC or low-format (in case of damage EMMC), CMD42 Lock/Unlock/Password reset or Samsung eMMC Factory Format. Our adapter allows you to connect in ISP mode (directly onto your phone without removing the EMMC) or Direct (by removing the BGA soldering and the corresponding memory fields or using adapter). Advantages of the use of an adapter:  - Full control over the VCC / VCCQ by connection of external power from USB - The ability to turn ON/OFF Pull-UP CMD and DATA (Dat0) to increase signal levels and improve stability - Lack of communication problems by applying the same path length for the transmission signals - The ability to connect the IDC 10 pin connector - allows use BGA adapters used in CHIP-Off for Direct Mode Features:  – eMMC/SD reading info, browsing through OCR, CID, CSD (and EXT_CSD for eMMC only) registers’ fields, edit separate fields and writing back to card, reading/writing eMMC card’s MCU’s internal firmware, etc – eMMC Firmware Update option – eMMC Firmware Reading option – CMD42 Lock/Unlock functionality for eMMC - user can set/change/remove password to protect/unprotected (lock/unclock) the User Area Partition – User Area Partition Forced Erase to erase Locked User Area Partition and to reset Device lock/unlock state and password (CMD42’s consequences) – Samsung Factory Erase which erases and re-formats the Samsung eMMC chips. Output signals on the adapter:  - GND - CMD (ON/OFF Dip Switch to enable/disable pull up signal - 100 ohm) - CLK - Dat0 (ON/OFF Dip Switch to enable/disable pull up signal - 100 ohm) - VCC (voltage regulation using two modes - 2.8V / 3.3V) - VCCQ (regulation voltage range in three modes - 1.8V / 2.8V / 3.3V)

RIFF BOX JTAG firmware/hardware supports communication with single or multi chained TAP controllers. All currently supported cores, according to IEEE 1149.1 Test Access Port standard, put 0b1 data into IR register upon CAPTURE state. Thus it makes possible automatic detection of IR register size of each TAP present on the JTAG chain. In this case IR ‘pre-’ and ‘post-’ stuffing bit sizes are not required to be specified by user and are determined automatically. All is needed is a TAP controller position number of the device user is trying to connect to. Includes:

• Riff Box
• Two 20-Pin Flat Tape
• Adapter

Adapter eMMC/JTAG for RIFF Box 2 Adapter eMMC/JTAG for RIFF Box 2 - Allows you to perform a very simple phone repair by JTAG, using IDC 20-pin connector, known from previous RIFF. It is also supports eMMC, using latest 30-pin connector (IDC 30-pin). Thus you can repair phones with blocked JTAG access (GT-i9300 / N7100 / N719 / N7102, etc.), repair phones with damaged JTAG points/pads (access to ROM2 by EMMC) or read/write EMMC in case then the data recovery/analysis is required. Using this adapter, you can perform format EMMC or low-format (in case of damage EMMC), CMD42 lock/unlock/password reset or Samsung eMMC factory format.
