iPhone and iPad NAND storage upgrades
On supported models, the internal NAND storage chip on an iPhone or iPad's logic board can be replaced with a higher-capacity chip through advanced microsoldering — a board-level upgrade, not a software trick. Walk-in service in Revelstoke, BC, with mail-in service across Canada.

What a NAND storage upgrade is
NAND is the physical chip on the logic board that holds your photos, apps and files. Increasing storage means physically replacing that chip with a larger one — not a setting, an iCloud plan, or a software trick.
NAND is a chip on the logic board
It's the same kind of solid-state storage that lives in an SSD, except on iPhone and iPad it's soldered directly to the logic board rather than living in a removable module. Whatever capacity it has when you buy the device is the capacity it has from then on, unless the chip itself is replaced.
Upgrading is advanced microsoldering work
A storage upgrade means desoldering the original NAND chip, programming a higher-capacity chip with the data the device needs to identify its storage, and re-soldering the new chip in place — all under a stereo microscope.
When an iPhone or iPad storage upgrade makes sense
A NAND upgrade is the right call when your device is otherwise fine and only the storage is holding you back.
Running out of storage
You spend more time deleting photos than taking them. "Storage almost full" warnings keep coming back.
Want to keep your device longer
The hardware is otherwise great — only storage is holding you back from another year or two of use.
Bought a lower-capacity model
Your device shipped with 32GB, 64GB or 128GB and you've outgrown it sooner than expected.
Preparing the device for longer-term use
You plan to hand it down, keep it as a backup, or use it for a role that needs more space.
Told storage can't be upgraded
An Apple Store or another shop said it isn't possible. On supported models, board-level NAND upgrades change that answer.
Supported models and maximum capacities vary
Contact RevyTech to confirm your device and target capacity before booking. Support changes between generations as Apple updates the storage architecture, and maximum capacity — for example, whether you can move from 64GB to 1TB — depends on the NAND chips available for your device's footprint.
The NAND storage upgrade process
Every upgrade follows the same predictable sequence, diagnostic-first, with no soldering work until you've approved the plan.
- Step 1
Confirm model & target capacity
We confirm support for your iPhone or iPad model and the target capacity before booking.
- Step 2
Backup & data preparation
Back up to iCloud or a computer. The upgrade may require a restore that erases existing data.
- Step 3
Device disassembly
The device is opened on the bench so the logic board can be safely removed for board-level work.
- Step 4
NAND removal & replacement
Under microscope, the original NAND chip is desoldered and the higher-capacity replacement is installed.
- Step 5
Board-level programming
The new NAND is programmed with the data the device needs to identify its storage, where applicable for the model.
- Step 6
Restore & testing
iOS or iPadOS is installed onto the new chip, the device is restored, and we run functional tests on the storage.
- Step 7
Final verification
We confirm the device boots, recognizes the new capacity, and operates normally before returning it to you.
Back up before any storage upgrade
A storage upgrade can require a restore, and a restore can erase data
Depending on your device, a NAND storage upgrade may involve restoring it from backup onto the new chip, and that restore can erase data. Please back up to iCloud or to a computer before bringing your device in or shipping it. We don't promise data preservation on a NAND upgrade.
If you can't back up because the device is dead, that's a different service — see our board-level data recovery page.
What to know before you book
Storage upgrades are advanced repairs that require diagnosis.
Realistic limits
- Requires advanced microsoldering — not a software or settings change.
- Not available for every iPhone or iPad model; support varies by generation.
- Manufacturer water resistance is not guaranteed after a device has been opened, and we don't promise it's restored.
- Existing board damage, such as liquid damage or a prior repair, can affect eligibility for an upgrade.
- Apple doesn't endorse third-party NAND upgrades; future Apple service on the modified board isn't guaranteed.
Why customers choose us for NAND upgrades

iPhone and iPad NAND upgrades are component-level work — what we do every day on the microsoldering bench.
Microsoldering experience
Stereo microscope, hot-air rework and the tooling required for proper BGA-style NAND work.
Device testing
Every upgrade is verified end-to-end before the device leaves the bench — boot, capacity, basic functions.
Local + mail-in
Walk-in service in Revelstoke, BC, with mail-in storage upgrades available across Canada.
Pricing, turnaround and warranty
No fix, no fee
Board-level work is no repair, no fee: if we can't fix it, you pay nothing. On mail-in repairs, shipping costs still apply. A simple repair quote by phone or email costs nothing. You always see the quote before we start any repair work.
Turnaround
Board-level work, water damage and severe damage take 1–4 weeks, depending on severity and parts availability. We will tell you where your repair sits in that range once the board has been diagnosed.
Warranty
90-day warranty on every repair — longer on screens and batteries.
Frequently asked questions
Straight answers to the questions we hear most about this repair.
Can iPhone storage really be upgraded?
Yes, on supported models. The NAND chip on the iPhone's logic board can be removed and replaced with a higher-capacity chip through advanced microsoldering work. Once the new chip is programmed and installed, the device boots back up with more usable storage. The first step is always confirming your specific model is supported.
Is this the same as iCloud storage?
No. iCloud storage is cloud space tied to your Apple ID — it doesn't increase the physical storage inside the device. A NAND upgrade physically replaces the storage chip on the logic board, so the device itself ends up with more on-device storage.
Will my data be erased?
It can be. A NAND upgrade is advanced microsoldering work, and depending on the path used for your device, the upgrade may require a restore from backup that erases existing data. We recommend backing up to iCloud or a computer before any storage upgrade, and we don't promise data preservation.
What iPhone or iPad models are supported?
Supported models and maximum capacities vary by generation and change as Apple releases new hardware. We don't publish a static list because it would go out of date. Contact RevyTech with your model and current storage size and we'll confirm whether an upgrade is supported.
Can I upgrade to 512GB or 1TB?
Maximum capacity depends on the model and what NAND chips are available for that footprint. Some devices can be taken to higher capacities, others are capped lower. Contact RevyTech with your model and target capacity and we'll confirm what's realistic.
Is a NAND upgrade safe?
It's an advanced repair. NAND replacement involves removing and re-soldering components under microscope, and the work is only as safe as the diagnostic and the technique. We start with a paid diagnostic, share the realistic risks for your device, and don't proceed without your approval.
Do you offer mail-in iPhone and iPad storage upgrades?
Yes, from anywhere in Canada. Contact us first so we can confirm support for your model, then start a mail-in request — approved requests get a prepaid Canada Post shipping label. See our mail-in microsoldering page for full guidance.
