What this means and what to do next
An iPhone stuck on the Apple logo (sometimes called a "boot loop" when it cycles on and off) is one of the most common iPhone faults we see. The phone will switch on, the silver Apple logo appears on the black screen, sometimes a thin progress bar appears underneath and partially fills, and then the phone either freezes there indefinitely or restarts and does the same thing again. To the user it looks like the phone is dying. To us, in most cases, it looks like a phone whose data is still entirely intact and recoverable.
What's actually happening is that iOS is failing somewhere during the boot sequence. iOS boots in stages: the secure bootloader runs first, then the kernel loads, then the data partition mounts, then the SpringBoard interface starts. A failure at any of those stages will leave the phone stuck on the logo. The cause might be software-level (a failed iOS update, corrupted system files, an out-of-date jailbreak) or hardware-level (a failing NAND flash chip, a damaged power management IC, water damage causing intermittent contact). Each of those needs a different recovery approach.
The crucial point is that your data — photos, messages, contacts, WhatsApp database, app data — lives on the data partition, separate from the iOS system partition. Even when iOS itself is corrupted beyond booting, the data partition is almost always intact and readable. Apple's recommended fix (Restore via iTunes/Finder) will erase that data partition without giving you a chance to back it up first. That's the trap. Recovery first, then Restore — never the other way round.
The four most common causes of an iPhone stuck on the Apple logo
1. Interrupted or failed iOS update. By far the most common cause. The iOS update process replaces system files atomically, but if the phone runs out of battery, loses Wi-Fi mid-download, or is restarted during the install, the system partition can end up in an inconsistent state. The phone reboots, finds the partial install, and stops. The data partition is completely untouched. We can usually rescue these phones via a forensic boot that reads the data partition without invoking iOS — recovery is fast and inexpensive.
2. NAND flash chip degradation or failure. Older iPhones (especially 6, 6S, 7) and heavily-used newer ones can suffer NAND wear after a few years of writes. The phone may have been working normally one day and stuck on the logo the next. iOS attempts to mount the data partition, hits an unreadable NAND block, retries, and gives up. Recovery on iPhones up to and including the X is via NAND chip-off — desolder the chip, read it directly, reconstruct the iOS file system. On newer iPhones (XR, 11, 12, 13, 14, 15, 16) the NAND is cryptographically paired to the CPU, so we use CPU swap instead — moving the original CPU and NAND together onto a working donor logic board.
3. Water damage causing slow corrosion. An iPhone that survived a brief water exposure may keep working for weeks before symptoms emerge. As corrosion progresses, charging becomes intermittent, the phone gets hot, and eventually a key data line on the logic board fails — typically just enough to break the boot sequence at the data-partition stage. By the time the phone is stuck on the logo, internal corrosion is well-established. Recovery starts with cleanroom inspection and ultrasonic cleaning; if cleaning doesn't restore boot, we move to chip-off or CPU swap.
4. Hardware fault — power management IC, baseband, or storage controller. Less common but it does happen. A specific component on the logic board fails — often the power management IC (PMIC) or the storage controller — and the boot sequence aborts at the same stage every time. Diagnosis requires schematic-level analysis of the logic board with a thermal camera and a multimeter to identify the failed component. We replace the component if it's a standalone IC, or perform a CPU swap if it's integrated.
How Data Clinic recovers data from an iPhone stuck on the Apple logo
We start with a forensic boot attempt. Specialist tools (we use a combination of the GrayKey-class hardware that's licensed to forensic providers, and our own internal toolkit) can sometimes boot the phone past the loop and access the data partition without invoking the failed boot path. When this works, recovery is straightforward: we extract the data partition, decrypt it using your passcode, and return your photos, messages, and app data. Roughly 40% of iPhone-on-logo cases resolve at this stage, often within 24 hours.
If forensic boot doesn't work, we move into hardware-level analysis. The phone is opened in our cleanroom and the logic board is inspected under a stereo microscope for visible damage — corrosion, burnt components, lifted pads from a previous repair attempt. We test the major rails (battery, PMIC outputs, NAND VCC) with a multimeter and thermal camera to find any short circuits or open lines that would prevent boot. Component-level repairs at this stage can sometimes restore the phone to working order, in which case we can also recover the data via a normal backup.
If component repair isn't viable, we go to chip-level recovery. On older iPhones (X and earlier), we perform NAND chip-off: the memory chip is desolderered with a hot-air rework station, read directly with a Riff Box or PC-3000 Mobile, and the iOS file system is reconstructed from the raw NAND dump. On newer iPhones (XR, 11, 12, 13, 14, 15, 16) where the NAND is paired to the CPU, we perform a CPU swap — transferring the original CPU and NAND together onto a working donor logic board, where they boot normally and the data can be backed up. Data Clinic has been doing CPU swaps in-house since the iPhone 11; see our case study →.
Recovered data is returned on a USB drive, an iCloud-restored phone, or via secure download — your choice. We do not retain copies of customer data after delivery and confirmation.

What our customers say
"I dropped my iPhone in the bath and was in tears thinking I'd lost three years of photos of my children. Data Clinic recovered everything. I cannot thank them enough."
"Phone stopped working after a swimming pool incident. The Apple store said nothing could be done. Data Clinic did it. Brilliant service."
"Reasonable cost, clear communication, and they were straight with me about what was recoverable and what wasn't. Recommended."
Frequently asked questions
Will Restore really delete my data? Apple says it might not.
On modern iPhones (iOS 11 and later), Restore via iTunes or Finder reformats the data partition before installing the fresh iOS. The encryption keys are erased as part of that process. Even if forensic recovery is later attempted on the NAND, the data is encrypted with a key that no longer exists. There is no "might not" — Restore is destructive to data on the phone. Apple's advice is correct in the context of fixing the phone, but it's not the right path if your data isn't backed up.
How much does iPhone-stuck-on-Apple-logo recovery cost?
Forensic boot recovery (where the phone can be booted past the loop): typically £195–£395. Component-level board repair: £395–£595. NAND chip-off or CPU swap: £695–£1,250 depending on the iPhone model. Free diagnosis. No fee if we cannot recover your data.
Can you recover data if I've forgotten my passcode?
If the phone is on iOS 11 or later, the passcode is mathematically required to decrypt the data — this isn't something Data Clinic or anyone else can bypass. If you've forgotten it but the phone is at the logo screen, the encryption keys are still in the phone's secure enclave; if you remember the passcode later, recovery becomes possible. If you've never known the passcode, recovery is not possible by any lab.
How long does iPhone recovery take?
Forensic boot: 24–72 hours. Component repair: 3–5 working days. CPU swap or chip-off: 5–10 working days. Emergency turnarounds available — call 0800 151 2207.
My iPhone has been stuck on the logo for months — am I too late?
Probably not. Unlike water damage cases, iPhones stuck on the logo are not actively deteriorating in storage — the phone is essentially off. We've recovered data from iPhones that have been sitting in a drawer for two years. The window doesn't close as long as the NAND chip survives, which it usually does.
What about Apple? They told me to take it to the Apple Store.
Apple's policy when an iPhone won't boot is to replace the phone, which loses your data permanently if you don't have an recent iCloud backup. Apple Stores do not perform data recovery — that's not what their service is for. If your data isn't backed up, get a recovery quote first; the Apple Store will still be there afterwards.
