I wrote a post on permanent hacking for symbian phones some
weeks back but some complained the method is quite complex and the
process was just too risky and complicated. Also it worked only on Nokia
phones only and you definitely need a PC to do it. The method I’ll be
posting today is quite easy and you can hack your symbian Nokia or Sony
Ericsson phone without a computer, a developer key and certificate. The
method was tested on Nokia C-7, Nokia N8, Sony Ericsson Vivaz, Satio and
a host of other symbian phones ranging from symbian ^3, symbian anna,
symbian s60v5 and s60v3. Now it’s possible to hack your symbian phone
without a necessarily flashing the phone.
You
can’t fully utilize the power of your Symbian smartphone if the phone
isn’t hacked yet. Hacking your phone allows you to install unsigned
applications and applicatios with expired certificates. You can easily
bypass installation error messages such as "certificate error,”
"certificate expired” and so on.

Unlike
the method I posted earlier, you have to perform this symbian hack on
your mobile phone and ther’s absolutely no need for a computer. First
download these files:
1.
Depending on whether you’re using a Nokia or Sony ericsson symbian
phone, download UMUNokiaHack or UMUSonyEricsson Hack and install. Launch
the application
2. Select your desired connection. Here you can select wi-fi or your default access point
3. Accept the trial key and accept the trial license too
4. Select Yes
5. Next, select No, then OK
6. Select OK and press 123. Now re-type 123 once more
7. Choose Options and click on Antivirus
8. Go to Quarantine
9. Press Options > Restore > Yes
10. Click Back, Home, then Exit and uninstall UMU Mobile Security immediately.
11. Enter 123 when prompted.
12. Now install RomPatcherPlus_3.1.sisx
14. Launch it and apply Open4All. This gives you access to all folders including system folders
15. Apply Installserver. Now you can install all unsigned applications.
NOTE:
If you see something like a red cross, then you still have one more
thing to do. There’s a link to installservers pack earlier in this post
and this is where to use it.
To know which installserver to use, you need to know your phone’s operating system. Go towww.gsmarena.com and
run a search for your phone to know the operating system and other
details. Below is just an overview of what the installservers pack
contain and corresponding phones they work for.

* Check the installsever compatible with your phone
* With X-plore or any other file manager you have, copy the installserver to to C:\sys\bin
* There’s no need to apply installserver patch in RomPatcher and your phone is now hacked.
This
hack works on symbian Anna, symbian ^3, symbian s60v5 and probably
s60v3. It works on Sony Ericsson Vivaz as well and I’ve read reports
that it also works on Satio too.
