Obvious is not the same, but the hardware can be equal, and this facilitates the process.

well lol if smeone gives a try then we can see lol...

Also dealink said tht v gt 2gb

I said I'm not sure, because in Russian Gb means gigabytes =)  I have not been able to carefully look datasheets and immediately laid out everything here for all to see and make conclusions...
Now I have carefully studied the datasheet and I can say that we have 256MB RAM = (
Nevertheless, we have 512MB ROM and I think we could all use...
We use all memory...

Various smartphones  has this chip (Xperia X10 Mini/Mini Pro, for example).
If one has that amount of RAM, we can unlock this function.

Yes, that's pretty much what I suspected. Just a minor nit, tmpfs mounts use no storage space (only RAM, but swappable, in case of memory pressure).

That's impossible, as the Blade would only be able to access 64 MiB of RAM (remember, all sizes in the datasheet are in bits, not bytes). The Racer's MCP has 2 Gib (256 MiB). As far as RAM is concerned, I don't believe there's anything we can do. As for flash, perhaps we could gain access to the whole 4 Gib (512 MiB), but that might not be such a good idea (think spare sectors).

well played my friend, i missed that part of the BITS!

i was calculating using Bytes

now its for sure that we cant expand the memory any further.

There is a lot of space unused in the system partition, same on the cache partition. Has anyone tried using a TPT to repartition the internal memory to get more space for apps? Are there any TPT's for the Racer around?

We will soon publish the manual for partitioned (for gen2 only).
Btw, what about the use free space in the system for swap?
remount system rw

mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system

make /system/swapfile right size (32M in example)

dd if=/dev/zero of=/system/swapfile bs=1024 count=32768

check available loopback device

losetup -f

we can see something like

/dev/block/loop0

create a loopback device

losetup /dev/block/loop0 /system/swapfile

make swap

mkswap /dev/block/loop0

swapon =)

swapon /dev/block/loop0

PROFIT!

I'm not really fond of this idea, since it would increase (irreplaceable!) flash wear. Creating a swap file on a memory card is one thing, but doing it on the internal flash? I don't think so...

everyone decides for himself ... I think I'll replace the phone before they wear out flash. In addition, the swap is not always used.

Unlock 512 MB ROM possible?
Here is a spec that shows 512 MB ROM.
http://mtsredenergy....-techspecs.html

Can we do it somehow using TPT method?

[deadlink]

we have 512M ROM, read this topic

Yeah. just read  
What if we use blade method for our racer?(i know that they mentioned " not for other mobiles")
Will phone be hard bricked?

[deadlink]

We use ALL ROM memory now. For what you would like to use blade method???

150+295.9+12.5+81.4= 539.8 MB   how can i get 539 if its 512 ?

My partition size is different than yours. Can i increase /system partition by deducting /data as  i need more system apps on /system.

Don't count the tmpfs ones. It should be possible to repartition the internal memory in the same way you can for the Blade, Skate, Blade 2. To do so you need to get a Racer TPT and edit some of the files.

why not just make an sd-ext with lets say 256mb ext3?
