View Full Version : ROM Upgrading - Why it works for some & not others...

I have now tried all the Roms (Helmi, Indra, Jwright, Ivan) and believe I have the solution for a stable upgrade. Individually they all work well give or take speed issues and forgetting inherent bugs we discover in beta versions.

However when we cross platforms - IE go from an Indra Imate base to a Helmi O2 base is always when I have struck real problems. I had been using Jwright's Imate 96 version for a month or so and just swapped to Helmi AKU 3.5 1.3. After flashing the Helmi ROM I had awful problems from pathetically slow response to the unit completely freezing after installing several large applications. However after a 100 or so hours of extensive experimentation I have several key reccomendations that form the solution.

Now I can say the Helmi 3.5 is blisteringly fast and stable followed by Indra & then Ivan and Jwright in the AKU 3.2 flavours. By the way I have also attached with this post my extended ROM that I am currently using with Helmi and it works a treat! (Basically it is many useful applications from Jwright's rom like Candello, loaded into Helmi less any incompatable applications.) Speaking about incompatable applications I can now unequivicably warn you NOT to load the following applications in the 3.5 flavour ROMs: (EVEN IF THEY APPEAR TO WORK)

Battery Pack Pro (no versions)
Resinfo 1.5
Voice Commander 1.5 (NOTE: 1.6 IS OK!)
Device Lock
Sprite Backup - current version (IT DOESN'T RESTORE PROPERLY - USE SPB BACKUP INSTEAD - ALSO ATTACHED)

Here is my list of recommendations as a professional systems analyst:

1. Before flashing the new ROM reset the existing one to its default factory settings but dont let the extended rom load. (IE reset again when the "will customize in 3 seconds" message appears)

2.After flashing the new ROM (and resetting it by pressing both softkey application hardware buttons & reset then selecting '0') THEN FLASH IT A SECOND TIME! (I don't have any scientific evidence to support this but I know it works a treat! - maybe some old registry settings or system files are not properly overwritten.)

3.Only load ONE APPLICATION AT A TIME then softreset then if the PPC is still working perform a backup using SPB BACKUP ONLY. (This way you also find out straight away if you have an incompatable application and then you can go and restore your last good SPB back up - without going back to the beginning!)

4.Using the supplied registry editor DELETE any Today plugins that you donot use. (Search for either 'TODAY' or 'ITEMS'.)

Lastly regarding memory leak. I am not convinced this occurs in any of the roms tested. Remember WM 5 - all AKUs uses persistent storage so movement in and out of memory will vary constantly and appear to alter for no reason because it needs to. (Helmi's 3.2 1.2 rom is a good example where the memory movement seemed far less than the others but I found this rom unusable one I loaded nearly 2gb of applications onto the storage card.)

Took a deep breath and start to try out your recommendations... despite that my device looks work quite well... but I always hope that good things can be even better :p ;)

Alternatively, unlock your extended rom, and delete all the files in it, hard reset, then flash with the new rom of your choice.

It has the same effect, only quicker.
