Chip-Off Data Recovery

We Offer Expert Chip-Off Data Recovery for All Flash Devices.

We use chip-off recovery to recover USB flash drives, SD cards, MicroSDs, eMMCs, CF/CFast devices, Monolith NAND chips, Microsoft Surface, and select phones (such as Galaxy S3, S4, S5, and other Android models).

Our first approach for flash-based data recovery involves using advanced reading modes or interfaces to recover your data without removing the chip(s). This method is faster and often yields better results, so we prioritize it.

If special reading methods, techniques, and interfaces fail, then chip-off data recovery is the only remaining option.

Chip-Off Data Recovery Process

Chip-off data recovery is a specialized technique employed for severely damaged devices where standard methods are ineffective. This precision process involves:

  1. Precision Extraction: Carefully removing the NAND flash memory chips from the device’s circuit board
  2. Specialized Preparation: Meticulously cleaning and preparing the chips for data access
  3. Memory Extraction: Using cutting-edge flash data recovery tools to read and capture the raw memory contents
  4. Virtual Controller Reconstruction: Virtually emulating the device’s controller architecture to properly interpret the data
  5. Data Reassembly: Reconstructing your files from the extracted memory fragments

This advanced procedure allows us to recover data from devices with severe electronic damage where the original controller circuitry is no longer functional.

Chip-off Data Recovery Rates

  • We charge $500 per NAND (flash chip) if we recover 99% or more of the data.
    • USB Flash Drives contain 1-2 chips.
    • SD cards contain 1-2 chips.
    • CF/CFast cards contain 1-4 chips.
    • MicroSD cards contain 1 chip.
    • eMMC/UFS/BGA (Microsoft Surface and various phones) contain 1 chip.
  • If we recover less than 99% of your data, you may decline the recovery for a $100 labor fee per flash chip.
  • If we can’t recover any data, there is no charge.
  • We charge a $100 “chip removal fee” (up-front/non-refundable) for some devices, like Microsoft Surface devices and phones (but it will be deducted from the $500 data recovery fee if the recovery is successful).

Monolith Data Recovery Rates

A “monolith” device is a single chip that contains the NAND (data) and controller (operating system). We charge $500 for chip-off recovery on monolith devices if we recover 99% or more data. If less than 99% was recovered, and you don’t want the data we recovered, there is a $100 labor fee. If the recovery is not successful, there is no charge.

In the right column, you can see an eMMC chip recovery from a Lenovo Ideapad 130S. In this case, the computer was damaged by a drop. We had to use a BGA rework station to carefully remove the tiny eMMC chip that contains the customer’s data. Then, we used a tool called “Z3X EasyJTAG” to read the chip and additional software to extract the customer’s data.

We can perform chip-off recovery for devices with the following problems (and more):

  • Bricked drive
  • Dead drive
  • Liquid Damage
  • Firmware corruption
  • Partition corruption
  • Logical failure
  • Failed or corrupt controller
  • Drive has wrong model number or capacity in BIOS
  • Broken phone screen
  • Broken phone keyboard
  • Phone stuck in boot loop
  • Broken USB interface/port

We use the best-in-class chip-off data recovery tools

This includes Ace Lab’s PC-3000 Flash, Rusolut’s VNR, Z3X EasyJTAG, and Flash Extractor. We also have many Multi-com adapters for MicroSD cards which enable us to recover data quicker than other companies that manually solder in leads to interface with MicroSD cards.

Microsoft Surface Chip-Off Recovery

Newer Microsoft Surface devices save their data on a chip soldered to the motherboard. When the device fails, the only option is a “chip-off” recovery. We offer the most affordable pricing for Microsoft Surface devices: $500 + $100 up-front/non-refundable to remove the chip (but it will be deducted from the $500 data recovery fee if the recovery is successful).

Whether you have a Microsoft Surface with a chip (Surface 5 Pro, Surface 6 Pro, Surface 7 Pro, or Surface Laptop 2) or a Microsoft Surface with an SSD (Surface Laptop 1 or Surface Pro 4), we can help recover your data for an affordable price!
