Vivo Y29S ISP Pinout solution

The Vivo Y29S ISP pinout solution provides a reliable, in-place method to interface directly with the phone’s UFS memory by locating and wiring the RXOP, RXON, TXOP, TXON

and RST test points on the motherboard; when correctly identified and connected to a UFS programmer (Easy JTAG, UFI, CM2, etc.) these differential RX/TX pairs carry the high-speed serial data while RST controls chip reset, enabling safe reading, writing,

If you’re searching for the updated ISP pinout for the Vivo Y29S (PD2443F), you’re in the right place. When working on UFS chip programming—whether it’s FRP bypass, removing MDM or user locks, recovering data, or fixing a dead boot—establishing a reliable ISP connection is the crucial first step. In this guide I’ll share the verified ISP pinout for the Vivo Y29S 5G that I personally confirmed, explain what each connection does, and show how to use the information safely and effectively for repair and recovery tasks.

What is Vivo Y29S ISP Pinout?

ISP (In-System Programming) pinout shows the connection points used to interface directly with a phone’s UFS memory chip. By using that pinout you can read and write the chip in-place with tools such as Easy JTAG, UFI, or CM2—allowing data recovery, firmware programming, and other repairs without desoldering the memory from the motherboard.

How to Use Vivo Y29S ISP Pinouts

Power off the device completely.

Remove the back cover and disconnect the battery.

Carefully clean the ISP pinout area on the motherboard.

Solder fine jumper wires to the RXOP, RXON, TXOP, TXON, and RST points as shown in the diagram.

Connect these jumpers to your UFS programmer or box.

Follow the specific instructions provided by your tool (Easy JTAG, UFI, CM2, etc.) to read, write, or remove security locks.

Tips for Mobile Technicians

Always use a high-quality microscope and precision soldering tools.

If you’re new to ISP work, practice on old or scrap boards first.

Double-check all pin connections before powering on the programmer.

Take clear photos or notes of your wiring setup for future reference.

When to Use the Vivo Y29S ISP Pinout

When you need to bypass FRP and traditional methods fail.

If the phone is dead or not detected by PC (EDL mode not working).

To read or write firmware directly to the UFS chip.
