Apple has implemented additional barriers for users who seek to avoid paying premium prices for storage and RAM enhancements on devices like the iPhone 17 Pro Max. For example, the 2TB variant retails for a staggering $1, 999, surpassing even the cost of high-end MacBook Pro models. However, one resourceful modder has discovered a method to save $800 through a meticulous modification process. It’s essential to note that his success hinges on advanced tools and an immense amount of patience.
Challenges in Upgrading iPhone 17 Pro Max Storage
To successfully upgrade the 256GB storage on the iPhone 17 Pro Max to 2TB, users require a specific NAND flash module, coupled with specialized machinery—resources generally inaccessible to the average consumer. The NAND flash chip found in the base model, manufactured by Toshiba, carries the designation ‘K5A4.’ According to insights shared by modder DirectorFeng on YouTube, formatting the flash drive for a 2TB upgrade necessitates complex machinery and extensive expertise.
The modder successfully replaced the existing NAND flash with a 2TB ‘K6B3’ module, accommodating the physical differences in dimensions through expert soldering techniques. This involved tin planting, followed by fuming with rosin to prepare the surface, and finally, securely installing the new NAND flash. The process isn’t as straightforward as it seems; after attaching the chip to the logic board, it must be firmly anchored using BGA black glue and subjected to a reflow soldering process, maintained at a temperature of 100 degrees Celsius for 40 minutes.
After completing the assembly, the modified iPhone 17 Pro Max was connected to a Mac for the iOS flashing operation. This phase turned out to be successful, marking a contrast to the modder’s previous attempt to upgrade an iPhone Air, where complications arose from incompatible NAND flash chips. Remarkably, performance tests indicated that the 2TB modified iPhone 17 Pro Max outperformed the original 256GB version, signaling a successful and worthwhile upgrade.

Given the intricate nature of this modification, it’s unlikely that most iPhone 17 Pro Max users would opt to attempt this upgrade independently. Most will probably seek out a qualified expert familiar with these advanced repair techniques to ensure a smooth transition.
