"No Service" after water damage

[boyq]

My Z5 got water damaged from fresh water pool. Everything was still working except that it didn't charge anymore.

I've tried a warranty claim but unfortunately, my phone has UB and it's rooted. The service center voided my warranty because the technician detected the unofficial firmware. When I pulled out my unit, it was already turned on. The tech noted corroded mobo from the results. I'm not sure if he opened up my phone but I was happy because everything was working again.

When I came home, I tried to insert my sim card which works with my spare phones. It says "No Service". I also can't see the sim number from the default "Myself" contact list in Phonebook. I tried manual and automatic search for network operators to no avail.

Do you guys think this is a hardware issue already? If yes, then I got a z5 phone which can't even handle the most basic purpose of one.

Bro, is your Z5 a brand-new or a second-hand?

It wasn't even a meter and less than 30 minutes of dip. I even clean it with drinking water after every splash. I suspect that the chemical seal on backglass may have been loose over time as this unit have been with me for almost a year already.

I've owned this for almost a year already.

Have u backup DRM key? If yes, you can simply restore it and relock your bootloader.

Warranty already expired :/. The price they're asking is too much. I'd rather buy a new phone than pay the warranty service contractor of Sony in our area.

I don't trust the water tightness of Sony phones anymore..

Philippines.

Although I reported a water damage (physical damage), they voided my last remaining warranty due to unofficial firmware (I have UB/root). It's not like I had the chance to revert to stock after the phone had been water damaged..

The network signal was still good before I handed my phone to the service center. I'm not sure if the moisture inside damaged the chip responsible for the signal or it was the technician's fault assuming he opened up my phone or whatever.

They should've done pressure test FIRST and dried up what's inside if ever it's the chemical glue that's faulty over time. But what they did was to check the firmware first! I heard pressure test wasn't done because of the unofficial firmware. That's just so stupid of Sony.

The service center contractor is Telecom Concepts Inc. or TCI-Sony Philippines. I’m very disappointed. I've been using their products since the good old Sony Ericsson days. Now, I'm thinking of switching to those with better and competent after-sales support. Maybe it's time to go the Apple way.

Oh. I sympathize with you. Apple is a pretty good one, if you can live without root, xposed and mods, since iOS 10.3 is really difficult to jailbreak.

Found this in another post.

"I'll try answer it.

the custom rom trigger sony's security system and lock the phone. you need to flash the security system partition to fix it. the stock rom tft bundle doesn't have the image file needed to flash the security partition. thus, reflash a stock rom won't fix it. sony's security system is also very secure and at this time no one is able to hack it."

I suspect this is what happened to my phone! Apparently Sony DID this! I can't believe they rendered my device useless. I could've continued drying the device myself using rice or silica. This is totally unacceptable.

Update: Here's the post.

Update2: This can also be hardware issue just like this post.

I have ordered replacement signal cable and back cover glue in Aliexpress already. I hope it's just a faulty/corroded cable as I'll try to repair it myself. :/

Mine got water damaged just by washing the screen under the tap . water got in and "no service", no front camera, blurred back camera , random reboot and no sd card problems appeared but i was lucky because it was summer and outside were 40c so the phone recovered in about a week but the sd card slot is gone forever...it can't detect any sd card so be careful with this sony devices because you can have big surprises.

I have dipped my phone on clorine water 3 times and it's water thight, just mic didn't work while it dries,

You need to verify if it's water tight by checking f the pressure sensor is changing when you press the screen ,that can maybe fin a little leak of the waterseal
