I emphatically don’t know if your i Phone will work again.
Your best bet is to bring your i Phone to Apple or an Apple certified third-party repair center and let them take a look at it. so stop agonizing over how you could have stopped it.
but unfortunately I can’t predict if a water damaged i Phone will work again.
I empathize, but please don’t leave comments asking for what amounts to psychic advice.
You can jailbreak your i Phone, i Pad or i Pod touch on i OS 8.4, i OS 8.3, i OS 8.2, or i OS 8.1.3 using Tai G jailbreak tool for Windows or PP Jailbreak tool for Mac.
You can jailbreak your i Phone, i Pad or i Pod touch on i OS 9, i OS 9.0.1, i OS 9.0.2 using Pangu jailbreak and a companion tool called Cydia Impactor which is available for Mac, Windows and Linux.
If you need help, then follow the guide below for the step-by-step instructions.
When the time is up, try to power your phone back on. Update If you do need to replace your i Phone, you should be aware of Apple’s Out-Of-Warranty service.
Just hold down the power button until you get a white apple and it starts to boot up. If your phone won’t power up, you’ll need to get it repaired, but take some solace in the fact that you’ve done all the right things to minimize water damage. Apple considers “liquid damage” to be outside the terms of their warranty, but may, at their discretion, provide Out-Of-Warranty coverage.
