Big storage or hard/soft reset ?

[Guest scottt]

Has anyone done the big storage on the M500 ?

I am very short on memory and would like to gain some extra va va voom

Have been looking and these 2 options look like the answer but unshure of the differences between them and the pros and cons of both, so any advice or coments would be a great help.

BIG STORAGE

How do you install the default cabs afterwards ? (do you need to hard/soft reset and copy them to pc before before changing the rom ?)

Can they be Installed to the storage card or will they look to install themselfs to the now missing extrom ?

Can it be reversed?

HARD/SOFT RESET

If you do the hard /soft reset trick can you use the extra space gained from not installing apps or is it still hidden ?

Haven't done the BigStorage hack, but Hard/Soft Reset works well for me.

You can use some of the space (you get loads more Main Memory, which you can use as storage or program memory), but the space the extra stuff takes up prior to install can't be re-used - it appears as ExtendedROM and is occupied by the CAB files that would have been installed.

:oops:

With Hard/Soft Reset you can reverse it - just do it again!

Thanks for that

Another question - when you are able to see the extended rom if you delete some cabs that you know you dont need can you then replace them with you own choice of cabs eg today plugins, so whenever you hard reset it will install you r replaced cabs ?

Not quite true Chucky me old friend. XDA developers have a cab somewhere which allows you to install amy programme to it......

Shall look for it

Heres one way

I recently managed to make my own ExtROM for my Magician.

A short howto:

1. First dump your rom to a SD-card, using the well know method.

2. Next get the rom to your pc, using ntrw

3. Using a Hex-editor, copy 2BC019C (HEX) till 3EC019C (HEX) to a file.

4. Mount that file as a virtual Harddisk (I use the virtualdisk-plugin for total commander)

5. Modify your ExtROM on that Virtualdisk.

6. Umount the Virtualdisk.

7. paste the contents of the (modified) file back into the rom-file, at precicly the same position and save it under a different name.

8. put the modified rom back onto your SD-card, using ntrw.

9. Flash your Magician, with the new rom.

It's a way to customize which things are installed after a hard-reset

Here it is courtesy of itsme from xda developers. Thanks.

Attached a cab file that will install a tool to lock/unlock and hide/unhide the extended rom.

( with 'unlock' I mean make it read/writable again )
