Adventures in firmware: the Nokia C7: Delight 6.2 edition

It's a fair cop, I just couldn't resist trying out another custom firmware for Symbian. At least in this case I had a willing volunteer, in the form of an old Nokia C7 which had been in heavy use for a year and which was in dire need of a clear out and rebuild anyway. Delight 6.2 for the C7 is freshly released, so I threw caution to the wind and flashed it onto what is now a two-and-a-half year old smartphone. How was the experience and what does Delight 6.2 firmware actually get you? Here's my report.

The 'Delight' series of firmwares is quite well known, of course, but this is the first time I'd tried one. The documentation pages are a little scattered and somewhat technical in places, but here's a plain English, summarised guide to what's different for Delight 6.2, compared to the stock Belle Befresh firmware:

As with previous custom firmwares, it all adds up to quite a lot that's different, even if you have to be something of a geek to appreciate half the entries above.

As usual, I won't go into the intricacies of flashing firmware onto Symbian smartphones - there are plenty of guides online and it's not strictly above board. Nokia doesn't seem to mind too much, unofficially, but the act of going down this route will void any warranty or right to support. Of course, you're probably flashing custom firmware because the device is quite old and well out of warranty anyway, so the chances are that this won't bother you. (For reassurance, though, see my postscript, below.)

In broad strokes, the idea is to download the Delight 6.2 firmware (a self extracting .EXE file) onto a Windows Vista or 7 PC, and put the files it contains into a 'RM-675' folder inside \Phoenix\Products in your PC's 'Program files' folder tree. Note that if you want a non-English version then you'll have to delve into the Delight documentation and add a few extra files in.

In Phoenix, you hook up the C7 in standard 'Nokia Suite' mode then 'Scan product' and then 'Open product', picking RM-675. Then click on 'Options' and remove the EMMC (optional mass memory content) option from the list of contents. Finally, click on 'Refurbish' and sit back and wait for the magic to happen!

Once rebooted, you then have to be patient, since the firmware goes through a number of initialisation 'phases':

Just leave it alone, the device will restart again in five minutes and you're then good to start playing. Here are screens of Delight 6.2 in place on my Nokia C7, to whet your appetite, should you plan on trying the same thing.

The first thing you'll notice is that all applications are pre-arranged in folders, such that (by default) there's no need to scroll the app menu. This is very much in the style of the 'old' S60 and, like that version, sub-folders are allowed again. So, for example, 'Tools' contains a sub-folder 'Xtras', which you'll see below; (right) In addition to the recent widget packs from Nokia, selected widgets from previous Symbian versions are here, plus some custom widgets like 'App Launcher' here...

Here's Vertu App Launcher in action, giving you a grid of your most recently used applications (the other tab is for 'most recently installed'); (right) Included here are backup and restore functions that aim to preserve most of your apps and settings between firmware flashings (via backup to memory card or mass memory), should you experiment with other firmwares.

Music Player gets several shots in the arm, with patches to improve overall sound via headphones and speaker, plus a huge set of extra EQ settings, shown on the right here...

Good to see geeky tools like Nokia's freeware Connectivity Analyser being included too; (right) X-plore, which was recently made freeware, is here too, showing the unrestricted access to the file system in this custom firmware.

ROMPatcher tends to be included in most custom firmwares and this is no exception. You really are on your own in terms of documentation for the various patches though. Some have names which are obvious, some.... don't; (right) having set everything up, I'm doing a backup, just in case...

'Resolver', also in the Xtras folder, includes wizard like functions for solving all sorts of occasional low level Symbian issues. There are about ten scenarios and settings it can sort out, we could really have done with something like this from Nokia years ago....

I've always said that I didn't want to experiment with custom firmwares for Symbian until official updates had ceased for the device concerned. We've just about reached this point for the C7, although I wouldn't rule out some more minor app or widget updates. What pushed me over the edge here was that, if you look closely, the C7 had a cracked screen and was therefore effectively worthless for general use - you may wish to take a slightly higher value view of your own pristine C7?

Comments welcome on my efforts above, on the Delight firmware, or on how you get on, should you decide to 'do up' your own device.

Postscript: In answer to several people's questions, I investigated how to get 'back' to stock Symbian, i.e. the official Nokia firmware. Turns out that it's trivial. Nokia Suite always allows you to 'reinstall' the 'current' firmware. It sees Delight as Belle Refresh and then happily toddles off to Nokia's (now password protected to outsiders) firmware repository to download the (400MB or so) full official firmware image for this phone and then flashes it quickly and without further prompts. Total time from playing with Delight to being back on stock Belle Refresh was five minutes. 

PS. Note that Delight 6.2 is also available for the Nokia N8 here.
