My iPhone 3g was unlocked using universal sim and jailbroken via
quickpwn. After using bossprefs to toggle switch on/off button, the
power and volumes buttons were not working. I had restore to factory
setting via iTunes and ended up with firmware 2.2, but such buttons are
still not working. The iPhone is even in locked status now and couldn't
be unlocked as the required power button is not working (leaving me
with only the home button which is functioning).
If this is considered
a hardware problem, what parts of the iPhone should be repaired?
can't send it to Apple as there's no support in my country, therefore I
have to fix it myself.

Re: iPhone 3g Power & Volume buttons aren't working
Hello, This is probably a hardware problem, even though it started happening after a configuration change. The part that connects the on/off button and the volumes is the same part. This flex cable connects these buttons (and some other parts) to the motherboard. This cable is frequently damaged when the Iphone is wet. The good part is that it is a cheap part, and relatively easy to install. You can find a replacement here: http://www.piezas.biz/epages/wwwpiezasbiz.sf/en_GB/?ObjectPath=/Shops/demo132390/Products/%22Conector%20flex%20auricular%22

I think your phone is SIM lock to be able to make it open line and to use other sim network bring it to a reliable cellphone technician they have the necessary tools and skills on how to unlock and make your phone open line..
Up until recently, those of us with an iPhone 3G had to use it on the
AT&T network. Not anymore! After months of development and
research, the guys over at the Dev Team have released the worlds first
3G unlock method. Unlocking will allow use of the iPhone on any
network, and also the ability to install 3rd party applications not
available via the App Store. This article will walk you through the
steps in order to finally free your iPhone.
you will need to download the QuickPwn software. It is available in
both Windows and Mac formats, and both download links are provided in
the resources area of the article below.
Make sure you are running the most current iTunes and iPhone
versions. You must have iTunes 8.0.2. You can check what versions your
iPhone is running by going to Settings->General->About on your
phone and then looking for Version and Modem Firmware listings. The
most current version is 2.2 (5G77) and the firmware is 02.28.00. If you
do not have these running on your iPhone, the unlock will not work.
Create a backup of your iPhone using iTunes.
the QuickPwn program, making sure you have your iPhone on and plugged
in via usb. Press the big blue arrow button to continue.
QuickPwn will search for the firmware file on your computer. It should
be able to find it on its own, so just press the blue button to
QuickPwn will ask you if you want to install Cydia, Installer or to
replace boot logos. In order to unlock, you MUST install both Cydia and
Installer. Once done, press the blue button.
is the tricky step. And not because its hard – its just so
time-sensitive! In order for QuickPwn to begin its magic, the iPhone
has to be in “Recovery Mode”. To achieve this, you are going to have to
press some buttons! Don’t worry though, QuickPwn will highlight each
step, and even count the seconds for you! First, you will hold down the
HOME button for 5 seconds (the home button is the circular one on the
face of the phone). Once that 5 seconds has passed, you will continue
to hold the HOME button down, as well as the POWER button for 10
seconds. The power button is the one on the top of the phone, that you
(duh) use to power the phone on and off with. After those 10 seconds go
by, keep holding the HOME button down, but release the POWER button.
Keep holding the HOME button down until QuickPwn tells you that the
process has begun.
sit back, and try not to have a heart attack. QuickPwn will write the
modified files to your iPhone, and for the most part, will keep you
informed of what it’s doing. You might see some random lines of code on
the screen of your iPhone, but it is nothing to be scared of.
complete, your iPhone will reboot and then be recognized by iTunes.
When asked if you want to set this up as a new phone, or restore from a
backup, select the backup option. This will allow you to choose the
restore point we just made before starting this whole process. The
restore process can take a while, so don’t sweat it. This is especially
true if you had a ton of music and applications on your iPhone. It took
about an hour or so for it to complete mine.
complete, look for the Cydia icon on your phone. Open it, and go to the
"Sources" section. Click the + at the top of the screen, then type this
web address to add the following source: http://apt9.yellowsn0w.com
the Yellowsn0w program and reboot your iPhone, making sure your with
SIM card is inserted. Wait about 90 seconds for carrier lock; if you
are still unable to connect, pull the SIM card out and try again
Try doing a factory restore using iTunes or QuickPWN and if you need to jailbreak it again, be careful what apps you download from cydia...some of them cause problems with jailbroken iPhones, just research online for which ones are notorious for problems
