Tamper/Void Indicators

[chickenbox]

A few months ago I replaced the usb charging board in my UK Samsung Galaxy S2, which meant unscrewing the back of of the phone and disassembling it a little. It all went back together fine and worked smoothly.

This week I've had a lot of problems with my service/signal, now suddenly it seems my phone doesn't know it's IMEI, baseband and isn't detecting any SIM cards. Also the "Cell standby" service uses up 70% of the battery, I think it's maybe a hardware fault.

After doing a factory reset with no avail I contacted T-Mobile and they've requested I send the phone to be repaired, which concerns me slightly.

Will they be able to tell I've had the phone disassembled and replaced a part? Like stickers or screw indicators? I assume if they realise I've messed around the warranty will be voided, and I'll be stuck with an expensive media player.
I'd like to cover up all evidence of tampering if possible.

I've never rooted my phone, so I'm not sure how this problem started.

A trained engineer will probably spot the replacement component anyway.

Unauthorised disassembly/repair inevitably voids the warranty, yes.

and I'll be stuck with an expensive media player.

You should still have the option of a chargeable repair.

I'd like to cover up all evidence of tampering if possible.

Advice on doing that would be contrary AF policy, I'm afraid.

Ah well. I'll get my wallet ready. Thanks anyway.

Just thought I'd update.
I sent my phone for repair last week, and got it back in 4 days. On the sheet it says the "Mainboard PCB" was found to be faulty and replaced free of charge - everything works now.
Looks like I got away with it, although I wouldn't recommend anyone else opening their phone whilst it's still in warranty, phew.
