Installing unsigned apps... For newbies

In all of my previous guides, I assumed my readers(like me) did not just want to install unsigned apps but also make their phones work how they wanted them to work, with the help of ROMPatcher for example. It has however been pointed out that this is not the case, some people just want to install unsigned apps. Because of the way my previous guides were made/written, they were confusing for the viewer so I've now made a newer guide that will ONLY demonstrate how to install unsigned apps, making the whole process absurdly easy.

Download the zip file HERE and copy the appropriate folder for your phone to your memory card.

If you're unsure of which version of Symbian your phone runs on, refer to my Devices List.

If for some reason you can't watch the video or it still isn't clear enough, here's a basic explanation of what you need to do:

1)Install Y browser and HelloCarbide from your Hacks(9.x) folder.
3)Open HelloCarbide and go to Options>Menu1>Yes
4)Open Y browser again and navigate to your Hacks(9.x) folder, copy installserver.exe to C:\SYS\BIN.
5)Restart your phone.

Please remember that any apps you install will be granted ALL capabilities. Don't go around installing naughty .sis files for goodness sake!

    after i did this hack i cannot install any other legal application, how do i deativate this hack?


  2. Vlad

    I wrote a tutorial about an even simpler solution that doesn't involve hacking at any level.

  3. G.R.G.

    Martin, that suggests that you copied the wrong file. What phone are you using?

    Vlad, using secman IS hacking, it uses AppTRK. Plus, it doesn't work with newer phones/firmwares so this guide(the one above) is the easiest way to install unsigned apps in any way. Besides, using secman you still have to sign the app. This method is so much more simple... Just copy one file over and you never need to worry about signing again.

    hi, 2 question:
    1. with the above methord, do i still need to install the cappsOn and cappsOff?

    2. with the above methord, is it i can just install any unsigned apps? do i still need to sign it to .sisx before install it?

    thank you.

  5. G.R.G.

    Allan, with the above method there is no need for capson/off. There's also no need to sign apps. Just install unsigned apps as they are!


  6. Arjen

    Martin: installserver.exe is a hacked version of the original installserver in ROM. Even though it can install most SIS files (signed and unsigned), it has a problem with software that is protected using OpenBit or License Manager (some of the software you can download using the Download! application on your phone is protected that way).
    The only way to install this kind of software is to remove the hack (run HelloCarbide again to make the \Sys\bin folder visible and remove installserver.exe from that folder - no reboot necessary). I wouldn't recommend this installer anyway, since it completely bypasses PlatSec which also allows malicious software to be installed (which for example can send expensive paid SMS's or spam from your phone - something you won't even notice until you get your phone bill or until your data-subscription is suddenly cancelled due to a TOS-violation).

    Thanks Mr-X. here another question, the Y-Browser is .sis file, meaning that it is unsigned. so will it be able to install before i hack the symbian? isn't that symbian 3rd edition only accept .sisx file type?


  8. G.R.G.

    Allan, Y browser is already Symbian Signed I believe so there's no need to resign it.

    Just try it.

    I don't think this method is perfect.
    Leaving holes for all the malicious software is not a good idea at all.
    IMHO the best way is to combine both methods:
    Use this method (which works on new firmwares) but not to install hacked "installserver.exe". Use it to install "00000001" (hacked root certificate) instead. So you can sign with "gensign.cer" only those apps, which needs to be signed!

  10. G.R.G.

    Yagiza, indeed this method is less safe than using Leftup's custom key and cert BUT when I posted that guide up, people still had problems although it only had a few more steps to it. The only reason I've made this guide is because it IS the easiest method.

    When a new, safer method arises that is still as simple as this, I will of course write up a guide and remove this one.

    I dont have C SYS directorium on my n95 8gb ..i have c: system but there is no BIN directorium there.What should i do?Tnx

  12. Anonymous

    Stefan , use X-Plore with "Show system files/folders" option ON.
    If after starting hellocarbide you still have no access to the folder, there's something wrong with your device.

  13. Unknown

    Tnx i figure it out:)
    But now i have problem instaling psiloc irremote. I have 3 sis files 1. psiloc iremote signed 2.drm signed
    3.crack unsigned. And that crack unsigned instals but still program not working. Same those 3 files before cople of mounts my friend used when he instaled it on his n95 8gb.But he signed that crack on symbiansigned or something like that:( Any idea what should I do?

  14. Anonymous

    Stefan, as I wrote above, don't use the method described in this article. Instead, use combination of this method and the method described here:
    This will allow you to sign any unsigned apps with an universal certificate from FCA00000 (most of them are coming already signed with this certificate).
    And this method will not break anything!
    Also this method won't open doors for viruses and malicious software to your device.

    i did it the way it was shown in the video, after doing it i cant install any application. It just says 'file currupt'. I have a N73 ME and i used hacks v9.2. Please help!

  16. G.R.G.

    Prabhjot, that's the wrong file. The N73 is a Symbian 9.1 device.


  17. Unknown

    oh alright, so how do i change it now? because after installing it i cant see the SYS folder in C:\ anymore, neither can i uninstall hellocarbide. Thanks for your fast reply, i've added you to my msn please accept!

  18. Unknown

    i cant install the hack 9.1 files just says file currupt. please help.

  19. G.R.G.

    Restart your phone and then run hellocarbide again but this time copy over the 9.1 installserver. Make sure you delete the old one first.

    is it really dangerous if I hack my N95-8Gb this way? is there a real big risk (how many %) that bad software will be installed on my phone?? viruses?

    I always download my software at ipmart-forum. Is that a site where I can download dangerous software?

    If it is really dangerous, can you please give me the link with the previous tutorial to install unsigned files (the tutorial where you need to install the software "selfsigned" and sing every unsigned software you want to install).
    And in this case, how can I uninstall this hack, please?


    PS: are there others sites where I can download hacked software?

  21. G.R.G.

    Hi Barbara,

    If you only install files that you know came from a legit source, there's of course a 0% chance of getting viruses. There aren't even any viruses for S60 3rd yet anyways.

    IP-Mart deals with cracked software so be careful with what you install from there.

    I've removed that previous guide from the blog as in comparison to this guide, it's far too complex for the 'normal' user.

    If you want more hacks, I recommend the Symbian-Freak modding forums.

    Thanks for the quick answer!
    Could you re-post the previous guide, or mail it to me at ? I already used that guide with my previous phone, so for me it is no problem. I also need the software/files for that hack.
    Could you also tell me how to remove this hack?

    I want to install the previous hack, because I want to install things I download from Ipmart with no fear. Or is it the same? If I sign a .sis file (with the previous hack guide) that contains a virus, will the virus disappear?

  23. G.R.G.

    Hi again Barbara,

    I'll see if I can find it.

    Even if you sign the apps from IPmart with the custom cert used in the old guide, you will still be susceptible to viruses as the certificate used grants the application all capabilities, so you're really beter off with this method(installserver.exe).

    I have a problem: there is a software which I can't install anymore (jar file EA.Mobile.UEFA. EURO.2008.v4.8.36). My phone (N95-8Gb) starts installing it, but at the end of the installing process, it says "problem with certificate". Installing other software (even unsigned) is no problem. what can I do?

    @ Yagiza:
    can you explain in detail how I can combine both methods, and also where I can find the software to do so?
    And is it enough to delete the file "installserver.exe" to undo this hack?

    Did you figure out how to use the combined methods?
    I'm intrested as well.
    Any idea how can I contact Yagiza?

  28. G.R.G.

    @Adam and Barbara, I no longer have the guide that included sing Leftup's cert so if you still need it, I recommend you head over to the Symbian-Freak modding forum.

    If I understand correctly, the difference is that instead of using the hacked installserver.exe(after you hacked the system so you can use c:) you use some hacked cert that can grant most of the permissions. Am I correct?

    In case this is true, the only difference is that the cert is able to grant less permission that can risk your system?
    Is there any way to be able to assign permissions manually?
    It's abit disturbing that there is an option for malicous app to auto send sms etc...
    If you guys could explain the security holes I'll be thankful.

    Hi Mr-X. Thanks for this simple guide. Seems to work perfectly. However, I do have an issue with certain installations though. I have installed unsigned Shut Up and RotateMe released by Samir. I have N95 8GB. It allows me to install without any hassle but when I try to run, it tells me "unable to execute file for security reasons". Can you please help me out in fixing this issue? My version is v20.
