What is hard reset technically - MDA II, XDA II, 2060 General

Hi,
In terms of hardware what does hard reset do in imate technically? I know it will wipe up the whole RAM. But how it is doing that, is it by initializing the whole RAM (128 MB) to a certain value, or just rebuild the memory manager again without affecting the contents of each byte. Because I want to know after hard reset is it possible to read, through a program, the memory contents as they were before hard reset.
Also does the hard reset after windows ROM installation differ from a hard reset without windows installation? :shock:

:shock:
The main memory in the XDA2 is not flash and as such if it stops being powered it will lose it's contents.
I think that hard reset simply causes the power to the memory to be interrupted meaning that the memory is then completely blank.

Idea for Anansky and those who can cook ROM for us

Just an idea for Anasky and others,
Why don't we create small ExtROM with only minimal necessary file and xBACKUP program to restore previous Data from SD card.
If we have complete backup data on SD card, we can restore back from SD card after Hard Reset. And we have big \storage folder size, since the ExtROM is small. This way we still can recover from Hard Reset and restore all program to RAM.
Just my 2 cents :lol:

Arto.
"minimal necessary" may have different definition for different people.
For me, I like the current idea to fully get rid of the ExtROM and install whatever we like afterward.
Jackleung,
Yes, but if you are far away from PC, and suddenly run out of battery, and your devices need hard reset......
Not everyday happend, but who knows :lol:

Arto
Another question: Is the now bigger storage usable for automatically installing software after a hardreset? Is it used instead of the (now missing) Ext_Rom for auto-install?
hi!
divide space between \storage and ExtROM can be done easyly, but i know only one good use -
place some apps to ExtROM which MUST start HIDDEN after hard reset,
now i know only one app which require this method:
http://wiki.xda-developers.com/index.php?pagename=IIWPO
any other apps, and apps was at ExtROM too, can be run from any place -
SD card or \Storage
xBackup resides in OS ROM, so, after hard reset it will appear and can be use for restoring backup from SD card or \Storage, so we don't need to place it to ExtROM fs.
Anansky,
So do you mean actually if the ExtROM is nothing inside, maybe some parameter to adjust \storage space, we can hard reset and get xBackup to restore the RAM to its working condition before we flashing empty ExtROM?
This could be the easier way for ExtROM to get max \storage space and working magician :lol:
Thanks!
Arto
yes, of course.
programs from extrom installed to RAM and after you restore they restored too!
you can download programs in ExtROM from ftp and instll it manually, from sd card for example.
Anansky,
Just my curiouscity.
Actually where is the modification for 27mb \storage take place? On the ROM or on the ExtROM?
Thanks!
Arto
Hi ANANSKY,
Why don't you tell others, what modifications you did in the ROM?
Please don't tell me the bull**** like "it is too complicated" and such...
I know what I'm doing...
We are hunting the missing RAM in wm2k5, maybe it will help if you FINALLY tell the story...
At least if you'd answer something like "NO, I will keep it for myself only".
This forum is here for sharing the knowledge i guess...

want to restart with a clean slate

I've already CID-unlocked, SIM-unlocked my T-mobile MDA last month. I've flashed my ROM with the xelencin ROM that I found in the forums, as I thought it had most of the initial tweaks that I was looking at. Since then, I've installed a whole bunch of new programs to test out, but now it feels like my phone is bogged down.
I'd like to clean my phone of all its memory and go back to the state when I just flashed my rom with xelencin. Do I have to go and use the RUU again or can I just go to my settings -> clear storage -> 1234 and reset? Will this delete all the programs that I had installed on my storage card as well or will the files stay there?
Hard reset
Yes, a hard reset will clear everything. You do NOT need to reflash the ROM.
thanks
thanks for the heads up. i'm assuming the memory card can stay in without any problems...otherwise i can just take it out until it restarts.
i've flashed the radio rom to 2.47.11 since the ROM was made (started with 2.25.11). Is it safe to assume it'll stay with the 2.47.11 after a hard reset?
memory
I never bother taking the memory card out but then I back it up to my PC occasionally. There are certainly reports of memory card problems.
The radio rom will persist through a hard reset.
If you have created short cuts, it is a good idea to copy them to the SD card for easy reinstallation.
storage card not effected
ok, just an fyi, I did the clear reset with 1234, ok. storage card isn't effected by it...only the regular phone memory is wiped...it seems everything, including the files that I had changed in the \windows director for foreign language (asukal's wince.nls) files...

Help needed on formatting internal storage

Hi,
I wonder if anyone can tell me how to format the internal storage on my XDA II (2003). I know the theory but for some reason I cannot access the boot options screen. I can soft reset, hard reset and get the boot loader screen. The camera and the record buttons work when the OS is running but when I press reset, camera and record all I get is a soft reset.
I have simple requirements of the XDA: phone, calendar, tasks and pdf reader. The tasks have ceased to function with the "no program memory available" error and I can't install the newest Adobe reader as it is convinced that Adobe reader 1 is still installed (it isn't)
I was hoping that a reformat and a hard reset would cure the problems but without access to the boot options screen I am at a loss as to how to perform the format.
I have tried leaving the battery out for 24 hours but that made no difference. So, any suggestions would be gratefully received.
Thanks
If you have Wm2003 Camera+Record+Reset should hard reset and format without menu
If you have wm 5 or 6, it should get you into menu, you should select No yes yes, and then press pad.
Did you try to hold Camera+Record and then reset? And remember that you should hold all 3 keys pressed for a few seconds, until menu appear.

Flash Rom Reduce Storage Space

I've asked this in a couple threads so sorry for the duplication, I guess I haven't communicated my question well enough. I think others may have this issue as well.
Here are my questions:
How can flashing a rom change Internal Storage size?
What can be done to prevent this?
What can be done to fix it?
Here is the story:
Prior to flashing 2.13 and Hard Reset I had TMOUS HD2 with Kumar 2.0 Internal Storage space capacity 688mb about 610mb free space.
After flashing and hard reset, I got an error about free space, hooked up to pc and Internal Storage displayed 120mb capacity and 3mb free space.
-I did perform a hard reset from the phone, (volume up + volume down + Power button)
I flashed to Kumar Rom and the storage capacity changed but it did not return to 688, it was like 218mb - not free space, total space - capacity.
I have been flashing roms on this and a HTC Sprint Diamond for over a year, never seen anything like this.
Can someone explain this to me?
