I am writing this piece to share my experience whilst trying and eventually succeeding in overclocking my Nokia N9 running Meego Harmatten, an open source operating system supported by hundreds of independent developers, doing sterling work to add to the user experience of the 'still born' Nokia N9.
Because I have very little IT ability and just basically mess arround with phones and computers the whole operation seemed a little daunting to me, I'd read a couple of articles and seen people Tweet about overclocking and thought it would be great id my N9 could run a little faster and maybe a little smoother, and a speedier processor could result in this as it would make things happen that much quicker. Now this piece is in no way a guide, in fact it's more of a meeting point for the things I needed and , hopefully a couple of tips to simplyfy things for anyone prepared to risk destroying a very expensive piece of mobile technology. Because of my lack of experience and skill, at one point in the early hours of Sun 6th May 2012 , I had 5 web sites, Twitter, Skype, Gtalk messaging my email account on my laptop and Terminal and file manager open on my N9 !! Multitasking isn't the word ? To be quite frank, without the tremendous amount of help offered and given by Arie at Everything N9 (@EverythingN9 on Twitter) I simply would not have managed it. So my intent here is to both run through what I did and put links to all the things required as a reference point, and for anyone using the N9 and Twitter I would reccommend following both @EverythingN9 and @MfaroTusino both very knowlegable and helpful.
My limited ability
I have used Terminal a couple of times on my phone for minor hacks and changes, but always find it a little daunting, the letters, symbols and spaces need to be copied exactly for things to work, and for someone with fat fingers and bad eyes, this is not always the easiest thing to do, however up to now, any error I've made has resulted in the phone simply not doing what I want and simply having to re type the command correctly, Arie was kind enough to talk me through quite a lot last night via Skype as well as messaging me some instructions, and I eventually managed to get the app required, installed and working.
The result is that my N9 now works noticably faster when scrolling, web pages load quicker when using the web and for me the whole thing was worthwhile, however if you are happy with everything on your phone and don't want a £500 paperweight, take this post as a story and not a guide, because that's all it is.
Starting the job and basics
To do the hack you need to first go to settings>applications>intallations>and turn on allow installations from non-store sources
You also need to go to settings>security>Developer mode and turn it on at which point if you haven't already done so, you get the option to install a number of apps, I'm not sure if you need them all, but personally I installed everything !Once you activate Developer mode you will get an icon on your apps screen at the bottom called Terminal, it is this you use to enter the text you need to perform changes on the phone. To do so you need to type devel-su and the default password rootme this opens the terminal and allows the changes to be entered.
The article that formed the basis of my actions was from Everything N9 blog here http://everythingn9.com/opptimize-for-nokia-n9/
but thanks to Arie I have a couple of newer deb. files that can be used which I will add links to, but the first thing you need to do before anything else is to install Inception- https://endno.de/~itsnotabigtruck/inception/
which allows you to overcome the built in security on the handset and so enable the hack.Follow the instructions carefully and until Inception is installed you can go no further and remember to type EXACTLY as shown eg devel-su -c /usr/sbin/pasiv NOT devel-su-c/usr/sbin/pasiv
Links and Conclusion
There is a link for the Inception deb here
Now my problems started about here, as the order and method of installation is not completely obvious and one thing you will need is a file manager on your N9, the one I use is this, no longer available at the store unfortunately but I have a link and find it the simplest to use http://22.214.171.124/pavp6mnpaelg/ul1n4ob54yvxnvv/%28n9indonesia.wordpress.com%29File+Manager.zip
You see in my ignorant bumbling along with the N9 I basically grab armel.deb.files and simply install once downloaded, you can't do this here, you need to access them from your Docs, so check once downloaded that the deb files are in user>MyDocs in the manager, mine were and all I did was download onpc and bluetooth to my N9, downloading via the phone should work the same !!
In the instuctions on the Everything N9 simply replace
opptimizer_1.5.2_armel.deb with http://www.appcheck.net/storage/opptimizer_1.5.3_armel.deb
and for opptimizer-ui_1.0.0_armel.deb http://www.appcheck.net/storage/opptimizer-ui_1.2.5_armel.deb
these are the latest available at present afaik.
Once you have the deb files on your phone and have checked they are in MyDocs go back to terminal and type cd /home/user/MyDocs/ making sure you use Capital M and Capital D in MyDocs
all you need to do now is to install the OPPtimizer debs in the correct order and you're there so type /usr/sbin/incept opptimizer_1.5.3_armel.deb
and wait until everything is installed and you are presented with anothet #
once this is completed the hack should be working and you can adjust the voltage on your phone via the app along with the processor speed. I left my voltage at stock and increased the processor to 1195ghz any higher makes the red warning come in and the additional speed, for me is not worth the risk, others have tried higher but I have a limit to the risks I'll take with my baby !
I have now used the N9 for a full day without issue, it did get 'warm' NOT hot after streaming from BBC iPlayer for 20 minutes, but battery life seems unaffected and overall performance has been quicker and smoother, so for me, thanks to a massive amount of help and luck, the whole exercise was well worth while. The app can be uninstalled like any other and a long hold of ten seconds on the battery key will deactivate it.
That's really all I have to say, other than read all the info on the site links before doing anything and don't try to rush it, also if you have issues, seek expert help, I'm not an expert !!
