Recovering Data From a Broken Android Phone That Won't Turn On: ISP, Chip-Off and the Encryption Barrier

Quick answer: If your Android phone won't turn on or its screen is broken, there is no need to panic, because the screen and the storage are different parts. Your photos are usually still on the eMMC or UFS storage chip. If the phone won't turn on at all, it can be read via the ISP method through the mainboard, or if that fails, via chip-off by removing the chip. The only major barrier is modern Android encryption. DSET evaluates these cases at the Ankara Hacettepe Teknokent lab. Hotline: +90 536 662 38 09.

Why are a broken screen and data loss different?

The part that breaks on a phone is the touch panel and the display glass. Your data is not on the screen but stored on the storage chip on the mainboard. Even if the screen is completely shattered, that chip is usually intact. That is why the answer to "my screen broke, are my photos gone?" is most often "no, they are still there".

The real problem is the phone not turning on at all, the mainboard connections breaking after an impact, or water ingress. In these cases the data stays on the chip but the phone cannot show it. This is where the lab steps in. A similar logic applies on the MacBook side, which we explain in our MacBook data recovery T2 M1 M2 M3 article.

ISP: reading through the mainboard

ISP means In-System Programming. In this method the storage chip is not removed. Thin wires are soldered to specific test points on the mainboard and the chip is read directly through these points. Even if the phone does not turn on, if the mainboard is intact, the data can be pulled this way. ISP is less risky than chip-off because the chip is not moved.

Chip-Off: reading by removing the chip

If ISP is not possible, for example if the mainboard is badly damaged, the last resort is the chip-off method. In this procedure the eMMC or UFS chip is removed from the mainboard with controlled heat, cleaned, and placed in a special reader to pull the raw data. This is a delicate operation; the wrong heat can destroy the chip and therefore the data. That is why it must be done in a lab with the proper equipment.

Method Is the chip removed? When is it used? Risk
Normal software read No If the phone turns on Low
ISP (in-system) No Phone won't turn on, mainboard intact Medium
Chip-off (chip removal) Yes Mainboard damaged, ISP not possible High

Encryption: the biggest barrier

Here we must be honest. Modern Android phones encrypt storage at the hardware level by default. Older phones use FDE (Full Disk Encryption), while Android 10 and later use FBE (File Based Encryption). The key for this encryption is stored in the phone's secure chip and works together with the screen lock (PIN, pattern, password).

So even if you remove the chip with chip-off and pull the raw data, that data is encrypted. Without the screen lock password, opening the content is practically impossible. While this sounds like bad news, it is actually proof of your phone's security. The recovery chance is highest when we have the screen lock information or when the phone was configured without encryption.

The truth about FRP and Google accounts

FRP, Factory Reset Protection, prevents a thief from bypassing your account. This is excellent for security but is an extra layer in data recovery. Authorized data recovery is done with the owner's consent and account information; cracking FRP or unlocking a stolen device is not a data recovery service, and DSET does not do this.

The most important lesson: backup

All these difficulties point to one truth: modern phone security is so strong that data recovery may not always be possible. That is why the safest path is backup. Back up your photos regularly with Google Photos or a cloud account. A backup is always cheaper and more certain than recovery.

DSET has operated at the Ankara Hacettepe Teknokent Beytepe campus since 2003. The initial diagnosis is free and if no data is recovered, no fee is charged. For honest information about methods and chances, see our what is data recovery and how is it done guide.

Frequently Asked Questions (FAQ)

My screen broke, are my photos gone?

Usually no. The data is not on the screen but on the storage chip on the mainboard. If the phone can turn on, the data is most likely still there.

The phone won't turn on at all, what can you do?

First the ISP method through the mainboard is tried. If the mainboard is intact, data can be pulled without turning the phone on. If ISP is not possible, chip-off is evaluated.

Will data definitely be recovered from an encrypted phone?

No, we cannot guarantee it. Modern Android encryption is very strong. Without the screen lock information, opening the encrypted data is practically impossible. We share this situation openly.

Will you unlock the FRP lock?

We do not provide FRP cracking or stolen device unlocking services. Authorized recovery is only done with the device owner's consent and account information.

Will a water damaged phone be recovered?

Often yes. Even if the screen and circuits corrode, the storage chip can usually be read. Do not try to dry the phone, do not open it, take it to the lab immediately.
