I’ve always been looking for ways to try and eke out the memory on my phone, and what with upgrading to Froyo with its App to SD functionality, I’ve been doing pretty well. Don’t forget, my phone is rooted so if you have a vanilla Desire, you can’t do what I’ve done here. Rooting is truly the way forward!!

Now I’ve had 4 days off this week, and this spare time that I don’t usually have, led to a bit of tinkering. In short, I started looking a bit closer at Titanium Backup Pro, which I’d purchased and use as a scheduled backup tool.

However I found a feature amongst the batch processes that intrigued me. It’s called ‘Integrate updates of system apps into ROM’.

When I hit the run button, it suggested 6 apps that could have their updates rolled into the ROM:

  1. Flash
  2. Gmail
  3. Maps
  4. Market
  5. Street View
  6. Voice search

What this means is that updated system apps, that are considered part of the Android OS, can be moved from taking up space in RAM, into the system ROM, freeing up valuable space. This was just the thing I was looking for to give me a significant RAM boost!

So I approached with caution, and moved Flash first. The documentation for Titanium Backup Pro suggests a double reboot after using this batch procedure, so after rebooting twice, I tested Flash and all was good. More significantly a large chunk of RAM was now free.

So, I then moved on and tried Gmail and Voice Search. Again, success! More free RAM, a total of 19% freed by this process, and everything worked fine after a double reboot. A double reboot is nowhere near as classy as a double rainbow BTW!

Spurred on by my success I decided to try Market next. To my dismay, the phone rebooted halfway through, and Market no longer worked, even after a double reboot!

So, in for a penny, in for a pound, I also tried Maps and Street View, with the same reboot problem halfway through and dead apps afterwards. Titanium Backup couldn’t help either, despite my attempts to restore things back the way they were.

So, with a heavy heart, I carried out a factory reset. The phone came back fresh as a daisy, and I set about getting back into the Market and reinstalling Titanium Backup Pro. Since my license file was installed on my SD card, along with the backups, it all came back up nicely, and I was then able to restore my last backup and have my phone back the way it was before I mucked it up. Yes, it was my fault, but knowing better now, I have returned to the process and moved Flash, Gmail and Voice Search successfully again and regained the 19% space. So I went from 89% used, down to 70% used, and though there have been some updates to Market and Maps, I’m still only at 80%, which isn’t bad, since at the last count I had 70 apps installed!

I’m keen to get the rest moved to ROM, but I’m not in a hurry now. I’m probably going to email the dev for Titanium Backup Pro to ask if there are any caveats with the integration int ROM, but if I get any further with this and do successfully move the remainder, I’ll be sure to post here.

The moral of this story? If you have a good backup, you need never be afraid to factory reset!!
