Data recovery from a dead Huawei Mate 10 Pro?

[Android Central Question]

Greetings,

The device was water-damaged, battery + screen + Charger IC were replaced, and it worked for 2 days.

During the 2 days, the charging was very slow. And it consumed 2-4 times the ampers it stored (I can tell by charging from a power bank with % indicator ) - a rough estimate.

I left it on the charger, at around 70% charged, left for a few minutes, and went back to see it completely dead.

4 days from a technician to another, no one was able to boot it up. Their final conclusion was that the CPU is damaged. And the device is non-fixable.

I heard that if the CPU was damaged then the internal memory is lost, too. And that I can't change the CPU while keeping the old memory as if they are digitally signed.

Assuming that the CPU was actually damaged, what are my chances of recovering data? Is it true that the CPU is irreplaceable (while keeping the internal memory) ?

Btw, according to them, there were no visible signs of burnt ICs.

I appreciate it if someone would suggest a better sub to post this.

Regards.

I always stressed here in the Forums , if you have important data back them up in multiple places such as computer,cloud,SD cards etc

If you had them back up in above mention u can get majority back if not they pretty much gone .

The SoC (System on a Chip), loosely similar to a CPU in a desktop/laptop, and the internal storage chip are separate so it's not a matter where their interchangeable or equal to each other. They are two distinct components, but in a smartphone both are soldered directly onto the logic board so essentially it's the logic board that is one unique item. This photo is a Hauwei Mate 10 Pro logic board, taken from the iFixit.com site (see step 12):

The chip highlighted in red is the SoC (processors), the chip highlighted in orange is the NAND storage (internal storage).
Replacing one or the other is doable but you'll have to pay up a lot of money (hundreds if not thousands) because it's a very intricate process to de-solder a failed component off of a logic board, and solder in a replacement. Damaging the board and/or surrounding components is a likely occurrence. Specialized tools and equipment, and trained skills are a must. Most service shops will just replace the logic board entirely, it's a big job just tearing down a phone to do that.

For those couple of days it was working, you should have used that time to back up anything you needed. Some phones do have some good water-resistant features but otherwise, once a phone is water damaged it's much safer to assume the phone has no to a very reduced use life let. Simply because visually nothing appeared to be 'burned' out is meaningless, if a component is damaged internally, that's a much bigger consideration.
But from this point on, be sure to set up a backup solution. Too many people don't and they risk losing important data.

Welcome to Android Central! There are forensic data recovery specialists that you could look into, but be aware that they typically charge hundreds of dollars to attempt the recovery.

Well, suppose you have made a backup copy of your data on your account. In that case, you can simply log into your Google account on another device and restore all the data. Still, if you have not done this, the situation becomes more complicated. If you have a faulty processor, you need to fix it first and make a backup copy of your data on your Google account. But there is a chance that your processor will not be repaired, so I can immediately say that you will not recover your data. In any case, in such a situation, it is best to contact DATA RECOVERY SERVICES, and maybe they will help you more than me.

Welcome to Android Central! Unfortunately, if a person posts this kind of question on the forums, they usually didn't have the foresight to make sure their important data was backed up or synced somewhere on a regular basis.:-\
