Ha.. finally I updated my good ‘ol HTC Desire A8181 to Jelly Bean.I don’t know how long it will suffer my testing though and how good the ROM from CyanogenMod 10 is.Anyways it was a very satisfying experience, as I always wanted to update the OS on my mobile as easily as I do on a desktop/laptop. But as I have short term memory loss problem ,let me try to recollect what I did in the first place . Also before you go ahead, let me tell you the following are instructions only for HTC and their ROM’s and in some cases specific to HTC Desire.So others back off unless you want your phone bricked .But I presume most of the others have similar or close to same instructions.
First of all you need to have guts and not a mobile with a shade of pink..ok just kidding.
Following are the prerequisites if you want to go ahead .
1)Creating backups of your existing data and please ensure your phone had enough charge left.
2) Install the HTC drivers for your phone.
3)Uninstall the HTC sync from your computer.
4)Set the enable USB debugging on your device.
5)Need to root your phone.How? Install unrEVOked3 recovery reflash tool from their site unrevoked.com .
6)Install ROM Manager from Play Store.
7) Select the option ClockwordMod Recovery from the ROM Manager.
8)Copy the ROM from http://d-h.st/Nax to your SD card.
9)Boot into recovery by pressing and holding down the Volume Down and Power buttons.
Select recovery and select backup and recovery next.Select backup in the next screen.
10) Select wipe data/factory reset and confirm in the next screen.
11)Select install Zip from SD card post step 10.Choose zip from sd card and select the cyanogenMod 10 ROM file by browsing to that path and select the file.
12) Go back after finishing installation and select reboot system now.
And there you go, you have the all new shiny JB on your device.
Mind you there are loads of tools and sdk’s from which you can explore more.There are sites like androidauthority and forum.xda-developers.com ,which will help you find loads of ROMs and instructions.I must confess, I spent a few hours reading ’em before taking the plunge .
Having installed it, I realised that the performance was not upto the mark, not to mention the various times it just crashed and restarted while opening media .Hence the desire to experiment with my desire, led to the installation of a lower OS, Ice Cream Sandwich.Having heard lots about a ROM called AOKP Milestone 6 (version 2) ,i decided to test drive it.But first, i wanted to check if my previous backup of Froyo was still existent.So I held the volume down and the power button and selected recovery and chose to install from the previous backup .After some time i was in familiar territory.So I downloaded the new ROM ( http://www.mediafire.com/?5nzio781hub8533) and the corresponding google apps(http://goo.im/gapps/gapps-ics-20120429-signed.zip) and was ready for the next round of installation. All went smooth and I am very pleased with the new OS.Let me test it out further and will let you know in case of any issues.Till then i will enjoy my Ice Cream Sandwich 🙂
