[Q] My friend rooted his phone, its bricked.

---

He said I can have it if I fix it, I have no idea what he has done to it.


It wont boot up at all. Just a constant black screen. I've installed some samsung USB drivers. And when I plug it in under my devices and printers there are 3 things listed when ever I unplug it they all disapear.

under unspecified it lists "SAMSUNG CDMA Technologys" "Samsung Mobile Modem" and "SAMSUNG Mobile Modem Diagnostic Serial Port (WDM) (COM4)"

So the computer does seem to recognize it when im plugging it in. but the phone does seem really dead.

What should the next steps be that I should take, any tips?

1. Take out battery. And put in after 10sec
2. Power on by holding volume DOWN, home and power all at the same time.
3. Once in download menu, press volume up to continue.
4. Flash any firmware using Odin. I believe the gio version is 4.4.2

I have tried this like 50 times taking the battery in and out to, but the phone will not power on at all

Sounds like a hard brick...

...my guess is that something went wrong when flashing - he might have tried to flash something with Rom Manager for example, all Gio owners must avoid doing that since it crashes the phone.

My phone is turned in to the repairman for the above reason wit the exact same symtoms as yours, i'll get a cost proposal (sorry for poor wording, i'm not proposing to you :) ) any day now. Hopefully it'll be cheaper than buying a new Gio...

Does anyone think I will have any luck with a USB jig?

Just return it back to samsung i've had that on my mini and it was unrepairable so i bought the gio just return it back to samsung

As i've said, the phone was given to me, no warranty or anything, just wanted to see if I could fix it, don't really want to have to pay for someone to do it

Usb jigs may work, but I had this tooo, a long time ago when I flashed a rom...
Put it on the charger, and you"ll feel the battery gets warm, but dont see anything...
It may be that the battery was almost empty and thus the phone shut off...
Mine was gone for 2 weeks, and I nearly throwed it away...
But then I charged it, maybe it could help, and tried gettin into download mode while on the wall charging, and it worked!!!
My phone was alive after 2 weeks of beiing dead, but I was too noobish at that time to know what excactly I did..
But I did had the same when connecting to pc, it says its a modem
