Hi,

I was wondering if anyone was working on the idle screen locked image issue. I have a couple of ideas but would like to avoid bricking this phone and so was thinking I might ask someone more knowledgeable than I before I try them. (especially if they are really stupid ideas that everyone has thought of and discounted already)

Anyone out there?

Hi, All I know is on eternity, & impression you can't change them. Mythic has a few differences, but I don't think thats 1 ? Sorry, tech guy will be along, but I don;t think you can,,, Quig

Cant change them. We all had many ideas. They are hidden somewhere. ENCRYPTED. They are not the same files you will find if you browse your phone with TKFE.

have you guys tried this already?

Lines 630 and 631 of the file nv_default.ini are

NV_SI_SCREEN_IDLE_IMG_TYPE=0
NV_SI_SCREEN_IDLE_IMG_INDEX=-1


(note that they are not with the other lines that talk about the idle screen)

Not sure what the image type means but indexing might refer to an indexed sequence.

and then lines 924 through 928 seem to set "01 Sunrise Beach.bmp" as the base of the sequence( which btw is reset whenever the phone is powered off/on because sunrise beach is always the first lock screen picture.)

NV_SI_SCREEN_IDLE_IMG=/SystemFS/Media/Picture/01 Sunrise Beach.bmp
NV_SI_SCREEN_IDLE_IMG_THEME=
NV_SI_SCREEN_IDLE_IMG_PICTURE=/SystemFS/Media/Picture/01 Sunrise Beach.bmp
NV_SI_SCREEN_IDLE_IMG_HOMESCREEN_BACKUP_PICTURE=/SystemFS/Media/Picture/01 Sunrise Beach.bmp
NV_SI_SCREEN_IDLE_DEFAULT_IMG=/SystemFS/Media/Picture/01 Sunrise Beach.bmp


What if we set the default images in the 924-928 lines to a new single .bmp and then disabled the index command?

"-1" as a value might be an "execute" comand rather than a binary setting because it comes up most often in lines like:

NV_SI_SET_LOCAL_TIMEZONE=-1
NV_SI_SET_LOCAL_DAYLIGHT_SAVING=-1

which are automatically reset values.

In other commands it appears that the boolean is "0" for true/on and "1" for false/off

-So-

If we installed a 281k bitmap in /SystemFS/Media/Picture/ , changed lines 924-928 to reflect that new filename and then set line 631 to "1" instead of "-1".........?

let me sum up by saying that I am a huge chicken and can't really afford to brick this phone right now. Do you know what happens when this phone throws up an error? can we still connect vie TKFE and restore the file?

Let me know what you think

You may be on to something with changing the location. But I dont see what changing the -1 to 1 would do. Or why it would be necessary to change it.

Hi,

It seems to me that the naming convention for the pre-set images suggests that the executable starts at the base image and has some sort of code that cycles randomly through images in that folder that start with 01 - 10 . I think that you need to disable the execution (by indicating "1" instead of "-1" ) so that you dont only replace "Sunrise Beach" and then get cycled through the rest of 02-10 of the pre-sets. I cant seem to write to the /SystemFS/Media/Picture/ dir so we cant even add "02 aaa.bmp" etc to see if the executable will find the highest named "02" file.

does that make sense?

Yes that directory is locked. but I havent tried to change the nv link to another folder which might work. I understand what you are saying with the -1. But wouldnt 1 just move in the opposite direction. That is if this is even what the -1 is for.

In Samsung's programing environment I don't think that -1 is opposite of 1. "0" and "1" are opposites meaning on/true and off/false. I am pretty sure that -1 means execute but you may be right in the sense that we might try leaving the index command at "= <blank>" instead of changing it to "1". especially because the query might only accept "-1" or nothing not some other binary value. I'll do a little more research...

EFS is a part of QPST. Yes we have used it and it makes no difference. It can do no more than tkfe.  Except it takes 10 minutes to load up the phone and when it crashes I get worried.

It has only crashed once. I have used QPST many times. But still prefer TKFE.

If you need the attached pic of the file system expanded further, let me know which folder/s you want to see.
