Format ROM memory

Hi all,
I'm french, so excuse my bad englsih.
I had a Pocket PC on Windows Mobile 2003 First Edition and i backup my system to my ROM memory. After a new ROM installation (Windows 2003 Second Edition), i can't see this backup file in ROM, and now i have only 1Mo in ROM Memory.
How can i erase the old backup file ? Total Commander & Co can't see the file also...
Thanks a lot for you help !
Regards,
Bertrand

Please specify exactly what device do you have.
(I am not familiar with devices that got upgraded from 2003 to 2003SE)
The reason you cant see your backup is because its gone. When you reflash your device (upgrade the ROM) the File Store (where you save stuff you don't want deleted during hard reset) is also formatted. The reason you only have 1 MB storage left could be one of two things:
A) The new ROM takes more space.
B) Something went wrong during the upgrade and the ROM was not properly partitioned.
NOTE:
There is no way to recover this data. It is recommended that you backup important stuff to SD card or your PC (ActiveSync has a backup function).

I have a PDA, a "Yakumo Alpha GPS" (equal to "Acer N35").
Yesterday, I installed wrong ROM to try to free ROM Storage, and the install have been down. So, I reinstall Windows Moblie Seconde Edition, and now my ROM Storage is 0.2 MO. (
So, yes, I think that an installation was down one week ago, and that's why i had less ROM Storage.
PLease, tell me it's possible to recover my ROM Storage...

Hi beber49!
I am not sure of the details, but I can point you in the right direction and after some searching you should have the solution:
Find a device with the original ROM, there are instructions in the wiki on how to backup ROM to SD then restore. I think if you manage to reflash your device with the original ROM you might get your storage back.
But be careful: If the reflash is not done properly, you may loose all of the free storage or even kill the device.
Sorry, that's all I have. Hope someone gives you a better idea!

i tryed that but no way to see these file...

Roms, hard resets and windows mobile.

Hi, I'm looking for more info on how the memory is partitioned between storage and programs. I don't quite understand how a hard reset is equivalent to a reinstall, and how it works.
Is there a site or book with more information on this? Any help or pointer would be greatly appreciated!

a pocketpc have ram and rom
rom is read only memory
the os is located in rom
and storage and application memory is in ram
how much you want to have free for application ram
and how much you want to use as storage is up to you using the memory slider
a hardreset or too long without batt
clear the ram leaving the os which is in rom
as the only thing on the pocketpc
which is why it's the same thing as a reinstall
because all the stuff you put on it are gon
leaving what the maker of the device put in the rom
but with 2005 things have changed a bit
here some of the flash rom is used for storage
and all ram is used for application memory
(though buzz and the lads made it so some of the ram can be used for stroage on older HTC devices which otherwise only have 32MB)
here a hardreset dont mean a reinstall
if you want to clear the device to default you have to format
the storage from inside the bootloader

I think what he meant is the one shown in "Settings"->"Memory"->"Main"
Think of the "Storage" as the hardisk of your PC and "Program" as the RAM of your PC. For WM5, when you soft reset your unit, the "Program" memory will be cleared off and program will be loaded again into this "Program" memory.
As for the "Storage", it is the `hardisk` where you have your OS installed. The OS is kept in the ROM (which I don't think is part of the "Storage"), and it is installed into your "Storage" everytime you perform a hard reset. (e.g. the "Storage" will be wipe clearn upon a hard reset). Anything that you do, e.g. edit file, add contact, etc. will be recorded/saved into this "Storage".

Thanks for the replies. So what I see when I browse the device, including the 'windows' folder, that's a copy of the operating system, and the original master copy is in the ROM?
So theoretically, I could go and delete the whole windows folder, perform a hard reset, and everything would be fine?
Has anyone already tried to see what could be reasonnably removed from the windows folder in order save 'storage' space?
Cheers!

no whats in the windows dir is the os which is stored in the rom
you cant remove things in the rom

I'll reply to my own question in order to close this thread and make it useful to others:
(from pocketpcdubai)
The Universal comes with 128MB ROM and 64MB RAM as compared to its predecessors who had the exact opposite.
The 128MB ROM is divided into 2 parts:
1) OS + Extended ROM (around 84MB)
2) Storage (remaining 43.5MB as shown above

o2 mini (asia)

Hi guys,
i've just downloaded the WWE_O2_1.12.00 and O2Asia_CHT_1.12.920.
I've managed to install and flash my rom to the wwe_02.1.12.00 version.
but the o2asia_cht1.12.920 is runable. nothing happens when i click autorun. wen i do a hard reset, the ext rom is not installed.
Any idea hw can i install e ext rom so tat even after hard reset it will automatically run by itself?
i'm desperate guys... help!!

any guys here can help?
i'm desperate!!

you think this is paradise for getting answer?
the stuff you get, I'm not sure how it looks like, list the contents here and someone may help you.
Anyway, if it is mostly in CABs, you would need to unlock your ext rom and copy everything into it.

hmm...ok thanks..
anyway how do i unlock my ext rom then?
this forum is so huge tat i cant find it
i've been searching up n low ... before i post this question.
and do pardon me.
i'm still very new to o2 mini (htc magician)

Ok, it seems that you can't unlock ext rom for magician. You will have to flash it. I won't recommend you to doing that though, until you are very confident of yourself.
Anyway, for the stuff you want, just have everything copied into your phone/SD card, and run all the CABs there, it will install everything for you. Perform a backup using SBP Backup to get an EXE file that you can use everytime you perform a hard reset.
Again, Magician ext rom can only be written by flashing it. Read the forum, I might be wrong.

thanks guys..
anyway i've given up on writing the ext rom..
btw.. i've jus flash my rom with e asia cht 1.12
after flashing it ..i realise tat my storage folder is missing.
any help?

Internal ROM

In my Asus P320 box, it says the device has 128Mb ROM, and 64Mb RAM. However, on the memory settings it says I only have a total of 30Mb for Strorage and also 30Mb of Total RAM. Any fix or it is a problem of the PDA ?

Well, what do you think where your OS is running
To make it clear: the ROM is the place you install your programs and also where your OS is installed, the RAM is just like in PC the place where the os and other software stores data for quick access, so you will never get the full ROM and RAM free!

Yeah, know any programm that unnistall the applications, some of those i've installed put files I dont know where and the windows unnistall program do not delete them. My apps dont install on the storage card, i tell to install there, but they keep on being installed on the mobile memory. =\

[Q] Windows Mobile 6 flash and ram memory

A few days ago I got a "new" windows mobile phone in, and I decided that I would cook a rom for it myself to get all the functionality I wanted, but after testing a few of my own and other roms I've got some questions about the different memories of my phone.
- It's a Sony Ericsson Xperia x1i, but I think my questions would also apply to other windows mobile phones.
- I'm cooking and running other peoples windows mobile 6.5.3 roms
- The phone has 512MB of flash and 256MB of RAM built in.
- I'm using Twinge Kitchen 1.10 for cooking the rom and importing cab's of the apps I want to use
I've tried roms of vastly different sizes, but the storage memory always remains the same. My question is, how is the flash memory on a windows mobile device used? I'm assuming the bootloader, radio and some other things might have their own partition, and then a partition for the rom, and one partition is for storage memory. Am I correct?
If I flash my phone to a small rom will the space I save on that be wasted? Is there a way to make the free space available as storage memory?
I've tried putting all the apps I wanted to install into the rom, and that worked fine, but on first boot they installed themselves into the storage memory, so I would have been just as well off by installing them after flashing the rom. Is there a way to add apps to a rom, and have them integrated in it in such a way that they don't require further installing after flashing, just running the apps from the rom like all the regular stuff is. (this is probably done by people who know how to cook roms, but I can't find an explanation on how to do it anywhere)
I would rather cook a minimalistic rom and use the freed up space as storage memory, and then install my apps manually, that way I could uninstall them whenever I wanted. Or would having those apps intergrated into the rom save me more space because they would be compressed?
Either way I would like to know if there was a way to increase the storage space, and make the rom space smaller. I guess I would need a partition manager for windows mobile/CE that can resize without data loss, and resize the rom and storage partition with the phone running, or perhaps on the PC, with the phone connected with the USB cable and running in bootloader mode.
I have another question about RAM, my phone has 256MB RAM, but it shows as about 200MB program memory of which about 50 in use with no apps running. What is the remaining 56MB used for? Is there a way to change this amount?
I have used Windows Mobile for quite a while now, but this is the first time I've tried cooking a rom, or even thought about partitioning the built-in flash, so to the more experience people the awnsers to my questions might be obvious, but to me they are not.

I have thought of one possible way to re-partition the built-in flash, but I don't know if this can be done this way without messing anything up.
I could run Android from the sdcard, and resize the partitions on the phone-flash while in Android, but is there even an app that will let you resize those partitions in Android? Would this work without data loss, or if not would the bootloader be ok so I could flash the rom again in the newly resized partition?

I've had three WinMo 6.x devices (1 GPS and 2 phones) and both were able to have things stored on its flash memory. In fact, isn't that where the "My Documents" folder is?

Yes, but I think you are mis-understanding my questions, I don't want to just store things in it's flash memory, that's no problem. I want to resize the partitions on the flash memory, using less flash for the rom, and more available as storage space.

I have been researching further, but I keep coming up empty. I can't find any android or windows mobile app that'll even let me see the different NAND flash partitions, let alone manipulate them.
I could try and get a linux partition manager to work on android, but the more I think of it, the riskier it seems.
I've also been looking into using MTTY, but I can't find any information on what the commands are, except for tasks 28,29 and 32, and none of those will help me. I don't know if MTTY even has the capabilities to manipulate the partitioning.
