I have been using v20 for a long time since it was easily unlocked. But my phone recently started to behave erratically, I could not start media gallery anymore. Camera was slow. Everything was slow and it rebooted by itself too often (couple of times a week). I also have 16GB MicroSDHC card and I knew that latest firmware touted better compatibility with large cards. So it was time to go with full format of the phone and the memory card and painfull reinstallation of all programs.
So, here we go. Backup of PIM. Copying of files from card to computer. (that was not easy, the card wouldn’t read in card readers anymore, but using the phone in USB mode, did it). Format the card. *#7370# for hard reset.
I used Nokia Software Updater, and it did it evil thing by upgrading me to v31 and loosing my regional languages in the process. There I was, having now choice between English and Hindu. Instead of Latvian and Russian. Luckily, this isn’t a rare problem. It happens often, because the phone is produced for one country, and has that country’s product code and regional languages are added before shipping only.
This is fixed by changing phones product code to correct region and doing NSU again. Luckily it is easy and free (with caveats about understanding the risks of messing with Nokia firmware using non-Nokia tools). I used guidelines for N95 product code change from thenokiablog and it worked for my N82 too.
Format the card. Hard reset. Format the card again. (just in case, you know).
Here I am now. The phone is much faster even with all the software installed.(I relate it to better support for the large cards). It eats less energy (true, as promised in firmware changelog). It is more stable. (true, not self-initiated reboots anymore). And yes, there are some problems with Opera Mini 4.2 as noted by other users(for me, it manifests in slow response when using My Opera sync). Because of the this, I hope that there is another firmware on the way.
It is not unlocked anymore. Huh. There is a way to do it (mapdrive method) discussed in great detail in many places on the web. But you need to have your own certificate to sign several programs required in the process and I do not have one. It seems that at this moment, our friends in China stopped creating such certificates. Boy, do I want to be in the line when there is a new place creating personal certificates.
