Jasjar extended_rom manipulating

[aseptic]

Did someone of you all talented and gifted people found a way to delete\add programs in the JJ extended rom?
i keep deleting them using the total commander and they keep coming back after a hard reset.
As i understand:
1) All cellular network operator specifications found in the extended rom are taking a lot of memory space that can be freed.
2) The anti-virus program is slowing the whole thing operation as it is allways running on the background.
3) I know other cab files i would like to add to the extended rom in order that they will be installed automatically after a hard reset.
What do you think?

You can find the three cab files for the CA anti-virus, backgammon, and Skype, on the xda ftp site. Go to wiki.xda-developers.com, find the ftp link most of the way down that page, scroll down to Universal, click on the link under Universal uploads, then click on the extended rom folder on the ftp site and Joe Bongo.zip under that.

Use add / remove program to uninstall these three programs - anti-virus, backgammon, and Skype. After they're uninstalled, in turn, tap on the cap file for each of these three apps and when the install dialog comes up, choose to install TO THE SD CARD.

It says there is a problem installing the anti-virus program on the SD, but it's not true, it works fine from the SD card. Putting the three apps anti-virus, backgammon, and Skype on the SD card frees up about 4.2MB of space in ROM (storage). :)

Don't hard reset and these apps won't wind up back in the ROM. You don't need to hard reset unless you are installing an new ROM.

Alternately, you can go the more involved route in the link below to free up a little more space. If you get the Joe Bongo extended ROM, you'll see that there are 7 other cab files in the extended ROM. They take up about 0.5 MB of space. I'm not going to hard reset my device to save 0.5 MB of ROM space, because it's not that much space and I'll lose all of my settings on hard reset.

Hi cool_case and thank you for your reply
what i wanted is something totaly different
1) i wanted to delete the files i do not need from the extended rom (to free up some memory)
2) i wanted to add programs i do need, to the extended rom (to make installation automatic after a hard reset)
as you probably know, when i remove programs allready installed (like the anti-virus) i am never 100% sure what registry changes were made (altough i am deleting all changes i know of, using a registry editor).

Hi aseptic,

One of the xda-developers aces will be fairly like to figure out how to create a special ROM image that doesn't have have the extended ROM stuff in it. You may be familar with the Anansky hack (and later easier methods) posted in early summer here for the xda mini (JAM) that freed up about 27MB of 'storage'.

okay i will be waiting

The thing about deleting things from the extended rom to free up memory is that the extended rom is already partitioned so deleting things from the extended rom will not actually free up space. It will only prevent the deleted things from installing the next time you hard reset.

We will need some sort of other hack to free up this partitioned space (big storage hack). Just deleting them from the extended rom will not do what you're hoping for.

Following the instructions listed on this page I was able to reclaim 15M+ for Storage and Programs on my JasJar.

Not to bore you guys with result details here is how it played out with application installation:

After hard reset with Extended ROM bypass (eliminating Backgammon/Antivirus/Skype)
Storage 39.52 Program 28.27

After first ActiveSync 4.1 Storage 34.53 Program 21.29

Installs with soft reset after each:

Resco File Explorer Storage 33.31 Program 21.39 (?)
SPB Imageer ' 30.03 21.35
Pocket Artist 3 28.08 21.55
Listpro 4 27.24 21.45
PhatPad 26.42 20.84
MS Pocket Streets 5 25.92 20.75
TCPMP 24.28 20.25
Magic Button 24.15 20.44
NewsBreak 23.32 20.25

also on 2G SD Card Pocket Informant / MS Reader / Weather Panel

Sync includes 1,235 Contacts / 3 years of Calendar / 2 years of email (3 accounts) (attachments on SD) etc.

Bottom line Storage 19.67 Program 14.86

I wouldn't consider this too shabby.
Darn sight better than with the fluff on Extended ROM.
Hopefully this may be of interest

:D

Thanks for the link to the hofo wiki with the very clear instructions for bypassing the extended_ROM installation.

What I had done before was use add-remove programs to remove Backgammon, the CA anti-virus, and Skype. Then, I used the cab files for these three apps found on the xda ftp site to install these three to the SD. This saved about 4.2MB of storage. People had said that this method didn't really remove the apps from ROM.

But, that's apparently not the case. I followed the instructions for bypassing the extended ROM installation above and wound up with about 1MB more of "storage" memory than was obtained by just removing the three apps above manually using add-remove. So, the method above works is a little better, because while you can manually remove the backgammon, anti-virus and skype, you can't manually remove the carrier settings.

Another good thing came of doing this -- Sunnysoft backup did a nice job of restoring settings, including Today Screen plug-in settings Haven't found any omissions yet, but as I don't sync pim data, can't comment on whether Sunnysoft does that.
