Please help Keypad Lock Password and APP

[Pawel W]

Hello i woud like to add APP depend of KLP.
I do this:

; *** KLP. Keypad Lock Password *** 

; Firmware: SL45i v56 
; Author (v55): XhjJxm 
; Ported to v56 by rc-flitzer 
; Release: September 24th, 2005 

; With this patch you'll have password input for unlocking keypad. 
; The password has to be coded in flash, look below for more info. 
; If you're using EKS (Eliminate Keylock Screen) patch, you have 
; to press # first before entering password. All other keypad patches 
; like "long press # for unlock" etc. don't matter anymore. 

; Thanks alot to all patchers of Chinese firmware v55! :-)

Please help me where is an error?

Hey, very good idea ! I think rc-flitzer may do this !

btw: Many thanks to all patcher that are keeping the sl45 alive !

[rc-flitzer]

I checked the patch and found the error (already talked to Pawel). It's not that easy to make it selectable because of the barred # key. I'll create a selectable version as soon as possible. Stand by...

[rc-flitzer]

So, now it's ready. I made a working version of KLP selectable. If selected it works like the previous version. If not selected, you can unlock keys with # key - but only short press. Sorry, I didn't manage to do it with long press # or with confirmation box.

Patch can be found in "Flash Patches" thread.

[Pawel W]

Thank you for your work :-)

Little hint:
You have to "descharge" short pression values (E9,EA) to add the long pression value (EB) checking.
Look to my Eliminate Keylock Screen v3.1 in S-ME45i flash patch thread

Or/and, look to how right softkey long pression works in Babysitter screen - button handler (it's just few byte before Keylock screen - button handler in original SL45 fw)

Sorry lalo, but it doesn't work that way...
How klp works (I don't know exactly, just ported the patch to v56): the routine for dialling emergency number has been trapped so that you can type in every number you want. Dialling is still only possible on emergency number. But after every keypress the keyboard queue is checked. If you have typed in correct number, keypad will be unlocked.
Additionally some check in FW for # key is disabled (line 0x362A72).

For selectable version I extended the password check like this: if function is disabled in app menu, only first char of keyb queue is compared. If it's # key you get unlocked. But this is done after a short press.

I know already, there IS indeed a possibility to have the "old" behaviour: I would have to trap 362A72 too and check if patch is selected. But that would **** up the code... Maybe some other day...

@rc

That's nice. With patch disabled in app-menu the "password" is just #?
What happen if we undo the "Press long # for unlock keyboard"? Does the msgbox be visible again? (I think not as far as I understand the patch)

Maybe you can create your own dialog with OK/Cancel Keyboard unlock...
I think lalo developed a patch for S45

Now works correct (if function in app is disabled, long press # unlocking keyboard), check Walek's modification http://forum.gsmhosting.com/vbb/show...&postcount=497

[trustkill]

Very nice code, thank you all ! (I haven´t tried it yet, but I think that it works)

[rc-flitzer]

*banging hand to head* Yeah, the easiest solutions don't come on my mind... Good work from Walek. For other profile/function number modify code in block 40CBxx.

[GoLL@B]

Is it possible to set selectable this line - 0x0311BC: EA207012 FAE030D7 too?

Then we have screen with text To unlock... But if I did depend of this line, when I press # my phone turns off... I checked it several times but I don`t see any errors.

[rc-flitzer]

Why is there a need to have the mentioned line selectable? You know that there's a password necassary (or if not selected at the moment: pressing # key). Any other one "testing" your mobile phone will see the pw entering screen. If he/she is smart, pressing "C" button will occur in mind, and then the former screen "To unlock press..." will appear!
I personally don't see a necessity in having this selectable.

About the problem itself: what exactly did you do with the line 0x0311BC? Of course it could be made also selectable. That needs more code and time to develope...

[GoLL@B]

I did:
0x0311BC: EA207012 FAE110CF

0x41CF10: FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF 88C0D7403600F2FC6C099AFC03F098C0
0x41CF20: FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF FAE130CF98C0FAE12ACFEA207012DB00
0x41CF30: FFFFFFFFFFFF FAE030D7DB00

But When I have Function 16 Profile 3 not selected (rest of patch is setted in the same function) When I press # I don`t have password and I see To Unlock... but for a moment my phone turns off automatically.

Can You check it and correct mistakes?

[rc-flitzer]

Patch is ready, it's an add-on. Look into "Flash Patches" thread.
