new project: modify the HR buttons (plz check it out)

[tizaktizak]

so...my idea goes like this...
1.what is the first thing u think of after your device got lost\stolen??
W.I.M.P (or any other anti theft program)

2.what is the second thing u think of???
what if the person who found\stole my device performed HR(?!)..

ok so what i was thinking of is having a way to change\modify the buttons sequence (witch every body knows) to perform HR so it will be like your own locking code..

****************
another thing that have to be done in order to prevent unwanted HR is to change the "1234" numbers u r being asked to enter when trying HR from the software to a personal code...
****************

unfortunately..i dont have this kind of tools and knowledge to do it so i'm asking u guys...

plz check it out !! it will upgrade the whole security issue...

Well there is also a thing like Clear Storage under the settings page wich also does a hard reset.

[tizaktizak]

u missed the point..i'm not looking for another ways to HR....

[Riel]

no, but a thief can use that instead.
Or upload a program to do a HR.

Best thing to do is to bake WIMP in your ROM so it will be active after a HR. And get a sort of 'own signed' HardSPL so your thief can not flash it.

But I think he could flash the HardSPL, anyway, i think not many thieves come that far :)

[sackbauer]

good point !

but where is this coded ?
it must be before device loads bootloader ?! and if so - this is then hardcoded on the mb ... which maybe a bit tricky to change..

but i am sure we do have some more into deep guys on board .. so why not give it a try .. and brick another device ;-)

[Riel]

I think olinex can fix a way to 'sign' a rom with your code, so the hardspl can only flash roms that are signed with YOUR code. Building those roms is not very hard from existing ones I guess.


I am only curious, if the device can be locked in that way so no SPL can be changed (without password/right code/right SPL rom). I don't think that is possible.

Building a functional ROM with antitheft program full running is not hard.

Also make sure, the antitheft program can't be killed by advanced taskmanagers.

At first, it should stay invisible.



But, unless an XDA-noob :p steals your phone, don't be worried. Just a hard-reset surviving should be enough for 99% of the thieves. No 'simple' thief will know about reflashing and SPL ;)

This looks promising! keep up the ideas!!!

YOu might want to look at this: http://www.pocketpc-live.com/pocketpc-softwares/ultimate-theft-alert-v3-for-pocket-pcs.html

i know it does not do what yo want, but i thought you may find it interesting because if there is some type of security development the messaging and locking features from her are very nice.

how hard will it be to take the official 1.93.456.2 rom and add W.I.M.P to it by cooking???

any links for a guide plz?

Maybe you can try cooking Ultimate Theft Alert v35! (http://www.pocketpc-live.com/pocketpc-softwares/ultimate-theft-alert-v3-for-pocket-pcs.html) into it. Already guides are there which can me modified for diamond. Look here (http://pocketpc-live.com/help-and-support/1461-extended-rom-installation-v35.html) and here (http://pocketpc-live.com/help-and-support/1575-install-uta-on-ext-rom-htc-devices.html).

I'm not a programmer....

but i think it's simple.. should go something like this:



if (diamond.stolen) ;
then do "change HR combination" ;
for i in buttons do
buttons.change;

end

[tizaktizak]

i wish i had known more about it and have the guts to try it :(

[tizaktizak]

ok....i was thinking about it while showering...
when u do "clear storage" u r being asked to enter "1234" to confirm...
all we need to do is change it too....

now...if we change the HR buttons sequence and the numbers to enter for HR from the software......what other way to HR u can use????

i think this is the best solution...

[tizaktizak]

anyone know how to do it?
