[bethedealer]

What is the use of this?

[boinger66]

then you can use it for storage... and or increase the page pool

nothing extremely important mainly ringtone files / themes etc.

by default i try and install all extra programs to my storage card...

EDIT: i did find out that if you didnt install the files that came with the touch... there is one file ... to do with the bioscreen driver software... allows the bioscreen to work properly..

[rklosinski]

couple of questions...
1) if i delete the files in ext2_rom, and hard reset in the future, will I need the files to restore my device?
2) what is the "bioscreen" driver?

[boinger66]

yes you will...

and the bioscreen driver is for the touch functinoality to work properly

what i noticed when i didnt install those files is that

when i pressed with my finger i had to be precise... i couldnt just guesstimate the area of touch and work successfully

for example the scrolling ... i couldnt scroll properly unless i just touched the scroll bar...

hence the bioscreen driver

[rklosinski]

thank you.

[bethedealer]

yes you will...


so you mean if I hard reset without putting back the files in ext rom, the device is not able to restore to factory default??? that seems dangerous...

[boinger66]

no it just stops the "modification process"

that you see when you first boot up your device

[rklosinski]

by 'modification process' do you mean the process that makes it a 'touch' rather than just a wm6 device?

boinger...i can only see 5 files in the ext rom, occupying ONLY 197K wth 9.74mb free...so my question is:
1. seeing that the small space those 5 files are using, is it necessary to delete them ?
2. where are the ringtones you mentioned ?
3. by "increasing the page pool", do you mean i can move the page pool to ext rom ? and how do i go about doing that ?
4. i think you`re brillant :)

[pentagon1]

boinger....and i don`t have dopodppc-athena.cab that you said you noticed in ext rom in an earlier post....
also....haven`t tried this yet..but...if i were to install programs to ext rom....would that be alright?.....and..one last question...why so much free space in ext rom...is it intentional ? surely there must be a reason...thank you

hmm in my ext_rom i have about 1 meg worth of files...

if your ext rom is occupying only 197k than i suggest leaving it

increasing or decreasing pagepool can effectively allow you to have more or less storage... there is a guide in the elf upgrading forums.. the general consensus so far is the htc touch functions best with a 4mb page pool
the ringtones i believe can be found in the ringtone.cab...

and thank you

and in response to pentagons post
it does have some other letters in front that is the end name... if you dont have it it must not be that important... i see the cabs are varying from unit to unit which is a bit odd... it could be possible that the network providers have changed the ext rom which is normal...

teh ext rom is used for storage... you dont install directly to the ext rom... but when you click device it is in essence going to the rom...

and yes the modifcation process is what makes it a touch device instead of a regular wm6

[ppc4]

boinger,

I've successfully been able to view the ext_rom on the HTC Touch and could probably delete the cab files from there because they're showing as not in ROM but they're only taking up about 200K in space so I'm going to leave them.

I can't however, write anything to the ext_rom area because it keeps saying it's write protected. I've followed all the items in this thread http://forum.xda-developers.com/showthread.php?t=297085 for being able to write to ext_rom but nothing seems to work. Installing to "Device" still installs to internal memory and any attempt to write to ext_rom (via copying or installing) still results in the write protected error.

Any ideas on how to set the ext_rom so it can be written to?

Thx,
ppc4

[boinger66]

thats for a different pda... so i wouldnt use those files unless you KNOW they would work... and i dont know if those will work...

now i dont know if its a good idea to write to extended rom because of hard resets ... in terms of installing programs there... iw ouldnt do it

[hyde]

Guy,

I'm able to unhide the ext rom but I am unable to write to it.
Anyone having this same problem?

[boinger66]

yes this allows you to view your extended rom... not write to it

and on mine iwas able to successfully delet files

Same here, able to delete file. I can add file to it but only about 1.8mb allow.

What if I want to keep the bioscreen software and nothing else in Ext ROM? What is the name of that please?

Thanks

[mk73rc]

Perfectly fine.

I am able to view & edit files.

I have attcahed list of files from my ExtRom

where is Bio Driver?

[sunnycheng]

Hi,

Would any one be kind enough to post the Cyberon Voice Commander from their Ext-rom? I have a Chinese Touch..and I must say...the Chinese Version of the CVC sucks.... Please post it here! Thank you so MUCH!!!!

[Valentin.H]

I activated this but i only had 2 files in it, the ext_rom is nearly empty actually, is this normal ?
That's excellent, 10 extra Mb in the phone but if I can't write files then it's pretty useless for me, what could I do with that much space ? :)

[hamidaddin]

where can i find the extended rom??

[Seed123]

Flash your phone with the ROM without extendedROM to get 25 mb more space..

[R3PUBL1K]

my Orange ROM only had the "ext2_rom" so i re-hid the ROM.


off topic: anyone know how to change the boot-down screen?

I cannot, everything I have tried still will not let me do it. I know exactly what to do as I have flashed all of my previous HTC phones....

Anyway, I was able to delete a bunch of things in the ExtROM but you cannot save anything to it so what is the point?

[hirad_sabaghian]

i have a htc advantage x7500 with PK Black ROM. ive unhid the extrom but is there a way to unlock it???

[daverage]

Sorry I am unclear.
What advantage is there to opening up the extrom. Will it give me usable space?

[shrgawi]

i'd like to backup my ext_rom
and at same time i want to change my MSN Live to the old 1400 one

i opend my Ext_rom and this is what i get:

Thanks to you I was able to view my Ext.ROM,I also backuped the files in it and deleted them form ROM,But I found that every time I did soft reset the files automatically come back! My question is 1.Is there no way that we can stop them coming back again & again after every S.R.(any reg. changes)? 2.If not what is the use of it? No offense, I mean should we hide it again?

i can't modify these values in the registry. what tools are you using?
MobileRegistryEditor doesn't work for me...even if i can modify other values in the registry.
