iOS Update, Restore Mode, and Alleged Hardware Failure

I am asking to request a technical clarification regarding statements made by an Apple Premium Reseller in connection with an attempted iOS update on my iPad.

Background

I own an older but fully functional iPad Pro with no known hardware defects. As the device could no longer be updated via my smartphone hotspot, I visited the Apple Premium Reseller to receive advice on new iPad models and to ask for an assessment of my existing device.

After a brief review, I was offered an installation of the latest iOS version for a fee. I was told this would be straightforward and take approximately 20 minutes, and I agreed.

What happened during the update attempt

The update process took significantly longer and ultimately failed. I was then informed that:

• the iOS installation could not be completed
• the device had entered restore mode
• it was possible that the update attempt had caused a hardware defect
• the only way to make the device usable again would be a full restore, resulting in complete data loss

I was also told that the reseller was not responsible for data security and that no error had been made. The fee was still requested in order to restore the device to a usable state.

Subsequent outcome

I later had the iPad restored and updated by another service provider.

The device now runs iOS 16.7.12 perfectly, with no detectable hardware issues. While the data loss did occur, no hardware defect could be identified.

Despite this, the reseller maintains that:

• on older devices (8–10 years), iOS updates can, in the worst case, cause hardware failure
• such hardware defects may occur during the update process itself

My questions to you is: (technical assessment)

Can a standard iOS update or restore process (including restore mode) itself cause a hardware defect, or does a failed update typically indicate a pre-existing hardware issue?

Is restore mode specifically designed to recover a device to a functional state without requiring hardware repair?

Is it technically correct to classify a device as “possibly hardware defective” after a failed update if it later operates normally following a clean iOS installation?

Are there any known scenarios in which an iOS update alone—without power interruption, liquid damage, or physical impact—can damage device hardware?

Do you consider it accurate to state that older devices “inevitably” risk hardware failure during an iOS update due to age alone?

My request is purely technical in nature. I am not seeking a legal or commercial evaluation, but rather a clear technical classification, as the reseller’s statements appear inconsistent with the later flawless operation of the device.

Thank you all
