I wrote this for those of you who were wondering how to convert numeric permissions (e.g. 0755) to written form (e.g. rwx-rx-rx) and vice-versa. The numeric form is used by the chmod command as well as in update.zip scripts etc.
I'm sure there are a million descriptions of this out there, but someone asked about this in the developer's forum, so for convenience, here's my explanation. For brevity, I will skip all of the theory behind binary and octal number systems as well as bitwise operations, and just give you the short version.
Permissons will always start with 0 followed by 3 digits, e.g. 0777, 0644 etc (that is just how octal numbers are usually represented).
These digits should be understood as follows: "0UGP". U is the User permission, G is the Group permisson and P is the Public permisson. So a permission of 0641 is User=6, Group=4, Public=1
Now for the description of the numbers (here's where you need some math). Each digit is the SUM of 3 possible permissions.
Read=4
Write=2
Execute=1
Some examples:
7 = 4+2+1 = Read+Write+Execute (ALL permissions).
6 = 4+2 = Read+Write
5 = 4+1 = Read+Execute
4 = Read Only
3 = 2+1 = Write+Execute
2 = Write Only
1 = Execute Only
You get the idea.
Now assume you want to give a file the following permissions: rw-r-r (common for system files).
This means User=Read+Write, Group=Read, and Public=Read
Numerically this would be User=4+2, Group=4, and Public=4
So all together, this would be 0644
Now how about rwx-rx-rx (common for directories).
This would be U=4+3+1, G=4+1, P=4+1.
Altogether: 0755.
Hope that helps. If it doesn't google is your friend. Your best bet is just reading about chmod, the linux command to set permissions. Here is a brief description about the octal representation of permissions used by chmod: http://www.tech-recipes.com/rx/697/unix-advanced-octal-file-permissions-with-chmod/
BTW, here is a great calculator: http://www.javascriptkit.com/script/script2/chmodcal.shtml
Thanks for this and those links. I'm gonna read up on it a little later after work.
exactly the explanation I was looking for. Actually ...better than I was expecting lol
I been wanting to learn more and this is a great start...thanks again!!
Thanks for writing out the explanation. Kudos for being able to tackle it with clarity! It can be hard to phrase correctly.
For those interested:

I'm not sure where you heard this information, but it's not quite correct. It's true that most permissions will start with a 0 (if you're wanting the first digit to be a 0, you can actually exclude the 0 and just use the last three digits to represent your permissions, so 755 works just as well as 0755 since the 0 is assumed unless otherwise specified), but there certainly is a reason for that placeholder and it operates in exactly the same way as the other bits, only it represents different values.
For the first bit (most of the times, a leading 0), the octal system is assigned these settings:
Set User ID (setuid) = 4
Set Group ID (setgid) = 2
Sticky = 1
The setuid and setgid are basically ways to get a program or script to run with the permissions of the owner or group owner, regardless of who is running the program (as long as they already have execute permissions of course) within the created process. This lets you temporary elevate privileges for a single process. This can be dangerous from a security stand-point, so don't mess around with it if you don't know exactly why you need to be changing that value.
The sticky property is a value (in Linux, it's only an applicable property for directories) that prevents anyone or anything from deleting/renaming a file or directory within unless they are the owner or root. It's usually used in areas that are world-writable to prevent users and processes from deleting data that isn't theirs.
In the -rwxrwxrwx format, the sticky bit is indicated by replacing the final "x" with a "t" (or "T" to indicated that the "others" category of permissions doesn't have execute permissions). The setuid and setgid properties are indicated by replacing the "x" in the appropriate place by an "s".
As you can tell if you read this far, you probably won't need to deal with that first digit that often, especially if you have trouble knowing when it'd be appropriate. Again, I've got to emphasize that setuid and setgid can be huge security risks if they are set on anything that runs the risk of a buffer overflow, so use them only when necessary.
While this information isn't as useful as the other digits in permissions, I thought some might be interested.

Android 2.2 sets the default hostname to android_dfhjkahdjksf or something equally useless.
To override this in Cyanogen 6.1 you need to set the net.hostname property with setprop Eg:
# setprop net.hostname mickey
My problem is when I try to set this up at boot, something always overwrites my change with the default. I have tried putting it in my init.rc, /etc/init.d and /data/local/userinit.sh and it is always reset to default by the time the phone has booted.
Does anyone have any more ideas about how to permanently set the hostname? It would be a good option to have in cyanogenmod.
UP. I'm very interesting too.
The root filesystem is stored in the boot.img and is expanded to a ramdisk every time you reboot. For changes to be permenant, you need to extract the boot.img file, extract the kernel and ramdisk sections, modify the ramdisk image with your changes, then recombine the kernel and ramdisk to a new boot.img and reflash it. You'll probably need to do this on a linux machine that understands unix permissions and ramdisk/cpio filesystems as well as having a good knowledge of linux and unix commands. See this thread:
http://forum.xda-developers.com/showthread.php?t=551711
note: your kernel may use a different "--base 0x19200000" option when building the kernel boot image.
Is there not a way to add a correlating line to the build.prop file?
EDIT: This doesn't work - whatever is setting the net.hostname writes out after build.prop is read.
I'm looking...
I did a search in the /system/etc directory for any file doing setprop (I'm using a miui rom) and found the following script. I did the setprop for net.hostname in there and it too is being overwritten.
search command:
grep -H -r setprop /system/etc
/system/etc/init.goldfish.sh
I'm running out of ideas other than using autostart to set it after reboot.
EDIT2: doh. I think I already knew this but it dawned on me that the default net.hostname comes from concatenating the "android_id" (found in the secure database table) to the end of "android_".
So seems more likely to reset it after reboot using a script (gscript to launch it manually or use autostart to launch it automatically at the end of reboot cycle).
Property net.hostname originate from services.jar (ConnectivityServices.java):
Code:
// setup our unique device name
String id = Settings.Secure.getString(context.getContentResolver(), Settings.Secure.ANDROID_ID);
if (id != null && id.length() > 0) {
String name = new String("android_").concat(id);
SystemProperties.set("net.hostname", name);
}
Maybe CM guys would change this to add another "if /proc/sys/kernel/hostname is different than localhost, use it for net.hostname too" condition.
I'm not using CM so it is up to you guys to make a feature request.
Another approach would be to set service in init.rc that would start your net.hostname changing script on some property being set just after net.hostname is set. You could use also:
Code:
on property:net.hostname=android_blahblah
...but that wouldn't be so handy since you will have to change that line in init.rc every time you make a factory reset.
Really interesting, thx !

Thanks a lot. I've been looking for this for the past hour or so. Traditional linux methods to set the hostname don't work... I think I'll add an option in cyanogenmod settings for this and submit it to Gerrit. Look for it to show up within the next day or two.
That's great m8! Cheers

underscores in hostnames are bad
The main thing I want to do is get rid of that underscore. Several of the places I hook up with with WiFi attempt to enter the hostname supplied during the DHCP conversation into a DNS. But underscore is illegal for this purpose.

Moving to Q&A
Current version: !IMEIme 2.2.0.4
Bug Fix
Fixed bug in use previous patch that could result in variable used before declared error.
Changed processing order when custom patches were to be used
The program will now process custom patches prior to editing framework.jar and build.prop edits. With new kernel patches requiring a new build.prop users would lose build.prop edits if the kernel was included in custom patches, the program will now patch any user modifications, then process IMEI generation and build.prop edits.
Updated to work with ROMs that do not include GSMPhone.smali
Recently, many ROMs are not including GSM phone utilities in framework.jar. I have added testing for missing GSMPhone.smali and patching via TelephonyManager.smali if necessary.
UPDATED FILES UPLOADED
MANY of the support files have been updated to the newer versions (smali, baksmali, adb and components).
I encourage you to delete all files in your existing IMEI Generator folder and use the new !IMEIMe.exe to generate the files necessary.
The devices.dat file if you've used the previous version has several issues that prevents the device model from being correctly patched on many of the devices. This has been fixed here and in the device list thread.
There is a known issue with the GUI when your screen settings are set at 125% in Control Panel - Appearance and Personalization - Display... I will work on fixing that in the next release.
Bug reporting thread for !IMEIme
Device list thread
New features:
Will patch GSMPhone.smali if present in framework... patches TelephonyManager.smali otherwise.
I chose this method since more ROMs are coming out for wifi tablets that do not have GSM phone information included in framework.jar. I was playing with CM10.1 and discovered GSMPhone.smali is not present, thus I was getting unable to patch GSMPhone.smali error, and there was no patching for an IMEI. In all honesty... this should be irrelevent, since IMEI is only utilized in cellular communications on GSM phones... however... some applications MAY (xda free does) require an IMEI to work, even on wifi only devices.
ODEX files still in the works
odex file support... I think this solution will work on odex file systems as long as the patching is done on the ROM prior to flashing to device (anyone using odexed system please let us know) and I am working on in place patching on odexed systems... however, I am not completely comfortable since there is a lot of work done by the device itself during odexing of the modified files... I am very hesitant since any mistake could render a bricked device and I don't have a system to test with prior to release.
Previous Important Changes
The new version of the IMEI Generator will no longer overwrite your existing devices.dat file with the current. To use new devices.dat file, delete the old one prior to running the program, or download the new one and unzip it in the IMEI Generator directory.
Device Communications not necessary in certain situations
If you select to Update ROM, using Serial Number based IMEI and do not select Encrypt IMEI, the program will no longer need to communicate with the device when performing its tasks. The framework.jar patch will not hard patch the IMEI in this situation as before. This is useful for patching a ROM for distribution to multiple people, since they will all maintain unique IMEI's. This is accomplished with the following change in the framework.jar
Code:
/com/android/internal/telephony/gsm/GSMPhone.smali
.method public getDeviceId()Ljava/lang/String;
[b]changed[/b] iget-object v0, p0, Lcom/android/internal/telephony/gsm/GSMPhone;->mImei:Ljava/lang/String;
[b]to[/b] sget-object v1, Landroid/os/Build;->SERIAL:Ljava/lang/String;
prior to patching in code to prepend "0"
.method public getDeviceSvn()Ljava/lang/String;
[b]changed[/b] iget-object v0, p0, Lcom/android/internal/telephony/gsm/GSMPhone;->mImeiSv:Ljava/lang/String;
[b]to[/b] sget-object v1, Landroid/os/Build;->SERIAL:Ljava/lang/String;
prior to patching in code to prepend "0"
To try to explain the above a little...
The above is always changed, no matter what IMEI generation method you select...
If you select Serial Number and New Type IMEI and not Encrypt: no other patching is done for the IMEI... this can be implemented on many devices, since each will have a unique serial number.
If you select Serial Number and do not select New Type: additional code is added to format the IMEI to the old standard ("00-" and "-"s)... this can be implemented on many devices for same reason.
If you select MAC Address or Encrypt (or both): additional code is added that results in the IMEI being hard coded, this makes it very much device specific.
If you select MAC Address or Encrypt (or both) and do not select New Type: additional code is added that results in the IMEI being hard coded as well as code to format the IMEI, this makes it very much device specific.
Use Custom Patch NOTE: This is only used when patching a ROM
This is going to take some major explanation, since I ran into so many possible scenarios...
One thing of note... the only additional lines added to updater-script will be for files in the base directory
The order of processing is:
1. Original ROM updater-script and files
2. Custom Patch zip file
3. Custom Patch folder
The program will utilize folders (from Patch zip file or Patch folder itself) named modboot, modsys, or system (not case sensitive in windows) as well as files in the base folder
Any files in modboot will be moved to the root of the **ROM**-IMEI.zip file and lines added to updater-script as needed
Any files in modsys will be moved to the system directory of the **ROM**-IMEI.zip file
If Custom Patch is checked...
/META-INF/com/google/android/updater-script is extracted from the ROM
the program will ask you to select the Custom Patch Folder
If there is a zip file present in the folder the program will ask if you want to use it
You have 3 options, "Yes", "No" or "Cancel"
Yes = Use the zip file
No = Don't use it, select another
Cancel = Don't use a zip file
If you use a zip file, it will extract the zip file and process the updater-script in it for any additional lines needed
After the above, any non-zip files and modboot, modsys and system directories in the Patch Folder will be processed
I chose this order so you can have a "go to" patch zip file, and test other additions by using the file, folder options prior to including them in the zip.
Example here:
I have my custom patches in folder /CM7/UserMods with these contents:
/META-INF
/modboot
/modsys
patch.zip
The program processes patch.zip first, then overwrites any files with the files in modboot and modsys
It also processes /META-INF/com/google/android/updater-script for any lines extracting files to /boot and adds them to the original ROM updater-script if not already there.
It then adds lines for any files originally in /modboot to updater-script to extract them to /boot
"New IMEI Type" of IMEI which no longer has the "-"s in it, but maintain backward compatibility for those who already have IMEI's generated or prefer the old style. When the new type is selected in the GUI:
NOTE: Per the IMEI standards... Using a single 0 prepended to the IMEI indicates a TEST IMEI for a country with 3 digit international code... while it should have no implications to us since we are not on a cell... it may provide potential country validity issues... I will monitor this and resort to 00 prefix in the new type of IMEI if necessary.
ADDITIONAL NOTE: Per the IMEI standards... For devices without an IMEI, they are to provide a unique serial number to be used... This program modifies framework.jar to allow this.
I am now patching framework.jar in the /com/android/internal/telephony/gsm/GSMPhone.smali file instead of /android/telephony/TelephonyManager.smali (this change is what allows the information to display in the about tablet information)
I am renaming and patching 2 functions... getDeviceID() and getDeviceSvn()
By patching the two functions in this file... the IMEI now shows in Settings... About Tablet... Status... no longer have to use external program or dial *#06# to verify the device is patched.
getDeviceID() shows it in IMEI
getDeviceSvn() shows it in IMEI SVN
You can rename or copy !IMEIme.ini to IMEIme.ini and the program will work.... useful for *nix users and probably mac users... since they have issues with special char actors (!)... While I like to use it in windows to keep the executable and ini file at the top of the file list in windows explorer... anyway...
The program looks for IMEIme.ini first and uses it if present... if it is not... it then looks for !IMEIme.ini (which will be there... because the program installs the generic !IMEIme.ini if it isn't ) This also provides a good way to keep your ini.. and see the new settings in the compiled in ini.

BUG REPORTING:
This program was initially ineteded to generate a unique IMEI based on your device S/N and update Dev's install zip files... it has become so much more, and as such there are many functions involved in this process.
Due to the complexity the program has taken on... far beyond what I initially intended... to report bugs please try to use the following as a template:
Function attempting: i.e. Updating ROM... In Place Upgrade... Update framwork saved on computer... etc.
Error Messages: any error message you receive... or the last message you saw prior to the issue.
End result: i.e. GSMphone.smali updated, ROM not... GSMphone.smali updated framework.jar not... etc....
Environment: ROM in same folder as IMEIme.exe... ROM on same drive as IMEIme.exe... ROM on different drive... etc. (same for framework if updating framework instead)
!IMEIme.ini settings: you can put your entire ini file if you'd like.
If you could take notes of EXACTLY what which selection in the GUI you have selected and any buttons you click on which prompt it would be EXTREMELY helpful...
As I said, this program has taken on functions I initially had not imagined including... the more features added, the more complex testing and tracking bugs becomes... I don't want to include a bunch of messages just for the sake of letting you know where in the code you are... would not be beneficial to you... more buttons to click for no reason, etc.
The more detailed you can be, the quicker I can see what is happening... otherwise I have to try to duplicate what I think you are doing when you get the error.
mr_fosi and martian21 have been very tedious in reporting bugs... I greatly appreciate their testing despite not needing to, and the manner in which they document what is going on....
Everyone should click "Thanks" on their bug report posts... they have been instrumental in getting the program where it is so far.
Background:
Some developers require a unique number that is supposed to be provided by hardware manufacturers that is unique to every device. This unique number (IMEI) is extremely important in devices utilizing cellular communications.
Since B&N has not registered IMEI numbers for the Nooks, the AOS's we are using do not acquire it as they do in other Android devices.
The developers that require a unique IMEI have been less than receptive of our devices and past methods to provide functionality to utilize their apps.
I decided to provide what I believe to be a viable solution to this problem.
What this program is:
It is a method to provide a unique IMEI (with reasonable certainty) for our Nooks.
It IS intended to be a supplement until IMEI is addressed in dev's ROM's.
It IS viable for Froyo... CM7... CM9... CM10...Honeycomb... MIUI.... AOKP... and others.
I can't think of any reason it will not work with ANY ROM you choose to utilize... if you run across one... just let me know and I'll see if I can't fix that.
What this program is not and does not do:
This is not a perfect solution to our Nook specific issues. Let me make it PERFECTLY CLEAR there is NO PERFECT SOLUTION We are generating an IMEI from something else... I use TEST IMEI patterns based off of our device serial number, to ensure apk devs wouldn't come down on us.
It is not targeting any specific AOS.
It is not guaranteed to be accepted by any other developers.
It is not intended to be the end all, beat all solution.
It is not intended to dissuade other developers from providing what they feel is a better method.
It will not cause any programs to show in the market. That has to be dealt with via APK developers and/or build.prop Manufacturer strings.
Potential issues:
There is NO legitimate solution to the IMEI issue we Nookers (TM) face... unless a group desires to register a block of them for our use... thus I am generating TEST IMEI's... ideal... no, but the only method available to us.
While I feel, with significant certainty, there will be no negative consequences from apk devs in general, I cannot speak for them, or their logic. This can easily be disabled by them again. That is on them, not me or us. By the same token, they can decide to stop providing their service for cause, I still have no control over that.
Above, I emphasize “with reasonable certainty” due to the fact that, in theory, you can wind up with an IMEI that 9 other Nooks that use this software has. That can only happen if the other 9 owners use this program and have a serial number within the same 10 as yours. This is even less likely with the New IMEI Type since it is using the right most 16 digits of a device serial number (and we know they all start with 2)
If everyone who has the same beginning 15 digits utilizes this program to generate an IMEI, you will all wind up with the same IMEI. Given the number of Nooks out there compared to the number of user's hacking them.... I find it extremely difficult to believe, with a reasonable certainty, that any 2 (much less 10) devices would ever wind up with the same IMEI generated by this program. This is prevented when using the New IMEI Type
What this program does/is capable of:
It allows you to extract framework.jar from a developers update zip file.
It will allow you to pull framework.jar from your Nook or use an existing framework.jar already stored on your computer.
It will generate an IMEI based on your Nook's serial number (or MAC Address) if adb is working on your system. If you have issues running adb via USB (ADB(USB)), it provides the opportunity to utilize adb via WiFi (ADB(WiFi)) for any computer-device communications.
It will provide you a method to manually input your serial number if you cannot connect to the device via adb. You can also input a “seed” (easy to remember word or phrase) and generate an IMEI based on the ASCII codes of the text you enter.
It will edit /com/android/internal/telephony/gsm/GSMPhone.smali to rename any existing getDeviceId() and getDeviceSvn() function to getDeviceId2() getDeviceSvn2() and append the patch to end of that file. NOTE: When the program "smali's" the resulting GSMphone.smali... it relocates the appended function to be before the renamed function.
It will save the patch as IMEI.fix, thus allowing you to utilize it for subsequent runs of the program. A caveat to this is... if you run it from the same folder on a friend's Nook... it will overwrite your original one if it is in the same folder or they will have the same IMEI as you do if you use Previous Run.
It will offer to push the patched framework.jar to your Nook... IF you opted to pull framework.jar from your Nook AND adb successfully worked to do that. This facilates in place upgrading.
It will backup the existing developers zip file appending “-IMEI” to it, distinguishing it is one this program has been used on. It will update this file, not the original developers file.
If there are issues with file names that become duplicate in a case insensitive OS such that windows is, it will warn you of this case and not remove the updated framework.jar to facilitate manual updating of the zip file.
Caveats:
This program is known to work on Java version 1.6.0_23 and known NOT to work on version 1.6.0_17 or earlier. If your system seems to work fine... but the nook does not give you an IMEI number... check your java version by typing this in a DOS window (start-run and type in cmd):
java -version
this will tell you the version of java you are running.
Java must be on your system. It must be in your system's path statement, or this program must be in the java/bin folder. It is possible that you must have java 32 bit version, this is being researched.
It will very likely break your swype, or any other app that utilizes IMEI for validation and you have used previous methods to circumvent their validation process.
It will likely break the same software if/when developers include a fix to the Nook IMEI situation in their AOS. Unless you opt to use this method again on their AOS to ensure you maintain the IMEI you used my program to generate.
Since I have opted to utilize test formed IMEI's to prevent duplicating someone's “real device” IMEI, software developers can easily shut us down again. That is their option. I am trying to provide a solution that is acceptable to both sides of the fence.
Closing statement:
As I desire to make this program as beneficial as possible... PLEASE provide any feedback and/or bug reports... just don't continue to push your ideals once it has been discussed... beating dead horses gets tiresome and just wastes precious time.

Looks like I have something new to mess with tomorrow night... thanks for working this, we owe ya!
Been looking forward to this! Thanks for your hard work DizzyDen.
Tested it out however it isn't finding 7zip. I've tried both the 64-bit and the 32-bit version (on 64-bit Windows 7). I'm probably doing something wrong if so please feel free to enlighten me

It wasn't you... there's something weird with the API to the fileopendialog that changes the working directory... a TEMPORARY work around is to copy the zip file to the folder you are running the program from.
Updating to beta 2 to auto extract support files on run.
Beta 2 is up... OP updated... note the bold text... for now the zip file must be in the same folder as IMEIme.exe
That will be fixed shortly.
Updated to beta 3. OP updated.
Fixed file browse for update file.
Improved cleanup behind itself before exiting...
removes helper files
removes framework.jar
removes classes.dex
removes out folder
removes system folder (the one used to add framework.jar to the zip file)
Still debating ability to allow manual input of the IMEI or a serial number... but those that want to do it will probably figure out how to do it manually... its REALLY not that hard.
Will add random IMEI generation as an option. The only purpose I see for this is for those who don't want to use the generic IMEI and cannot get adb working... even with the included adb in this program.
Feedback and bug reports are welcome and will help improve the program.
Thank you for this
I had to copy my AdbWinApi.dll for it to work. It did not put the new framework.jar in the zip though. It made the files, but didn't update the zip. I moved it to the root of my drive and ran it as administrator, but it still didn't update the zip. I am using Windows 7 x64. I used the IMEI.fix file and updated the zip myself. Thanks again for this nice tool.

Did you use something prior to b3 ?
There was an issue I discovered that was preventing appending IMEI.fix to TelephoneProvider.smali that was fixed in b3.
I did my development on windows64 so that shouldn't be an issue.
As for the dll... I hadn't experience issues with that... but I can certainly add it to the program.
Both adb dll's will be included in all releases after b3.
Good job!
Can you explain more about how rom is being affected?and what to check?

Please make sure b3 is the one you are using. When you originally posted... the thread was showing 0 downloads of that file.... or just wait a few minutes... beta 4 is on its way shortly.
To ensure TelephonyManager.smali is not changed you need to look in two places.... the easiest way is to search for getDeviceID
If it worked correctly you should find 2 instances... the first is the original function and my program renames it to getDeviceID2()... the second should be the one !IMEMe adds to the end of TelephonyManager.smali
Additionally... could you check and see if your run is actually overwriting update zip file.... see if there is a update ".zip.tmp" file left over... if it is there... the zipping is running into an issue overwriting the original file... I thought I had that issue worked out... but may need to add a check for that within my program.
I d/l b4, dropped it in a directory with just the .zip for n87 and ran it (win7 pro 64-bit). It errored out and here's the play-by-play of each of the windows which popped up one immediately after the other:
- I was warned about you being an unverified software publisher, which I OKed.
- "Windows cannot find 'java'. Make sure you typed the name correctly, and then try again." I OKed this one as well.
- window titled "DizzyDen's IMEI Generator" containing: "Return Code is:0 and Error Code is: 1"
- window titled "DizzyDen's IMEI Generator" containing: "Java is required on your system. You can download the current version from http://java.com"
I have JRE6 on my machine, though it is not in the system PATH.
Oh, and there were files for 7za, adb, .dll's and .jar files left behind.

java will need to be in your path... I have no way of including all possible locations of where it could be installed... and it is way too big to include with my program.
The left over files is due to the program exiting when it did... I will fix that in next beta... should have waited until java was tested to extract them... or have it perform cleanup before exiting on any errors... sorry bout that.... you can leave them... when you have successful run (or run beta 5 or later) it will clean them up.
For now you may have to run as administrator.... I will try to add code to avoid this in the short future.
BTW. Nowhere does getDeviceID does it say that it must be a well formed IMEI.

As much as I admire your work... I am honored that you are even checking this out.
I do understand that as of now it is not required... but I figure if I utilize standards (as much as there are anyway) we may avoid future issues if dev's start checking for well formed IMEI's.
I figure if I'm going to make this... I might as well make it right.
As far as I can determine... if a sw dev implemented IMEI checks, the only thing that could cause them to shut down someone using this would be to check that it is a "TEST" IMEI... but I don't see that happening, because hardware manufacturers do use these in testing.

Roger that. Should the instructions then note either the required change to PATH or that the file must be run in the user's jre#\bin directory?

Did you find the information in the thread linked in response to your questions?
TY mellopete for that.
- Plugged NC into USB port.
- Copied new B5 exe and n87 zip to java\jre6\bin directory.
- Ran exe as admin.
- Prompted for .zip check ("is this correct") and it was, so I OKed it. Not OKing it gave me the option to browse for the file, which I cancelled, resulting in a termination of the prog with a few more dialogs. Any extracted files were cleaned up an prog close, except for adb.exe (which I deal with below).
- Re-ran, exe, chose the detected n87 .zip.
- Displayed correct serial.
- Displayed correct generated 17-digit IMEI.
- Dialog contents "Modifying" gave error "Unable to open file", which I OKed.
- Several more dialogs flew by in rapid succession without error, ending with "Updating ROM" overlaid by "Updated ROM file has been saved as: cm_encore_full-87-IMEI.zip".
- Not all ancillary files were cleaned up. Two files remained: 1) IMEI.fix, a plain txt file containing the correct code to insert the generated IMEI and 2)adb.exe which could not be removed because it was still running the devices server. Running "adb kill-server" in the java\jre6\bin directory allowed me to remove adb.exe.
- A check of the modified smali showed only one instance of "getDeviceId" indicating that the smali had not been modified to add the code to spoof the IMEI.
I would also not have been able to eject my NC, had I tried, until I killed the adb server. Looks like one more line of code to add before cleanup.
Hey Guys,
I know there is an app in the market already Keystore Unlocker, but it doesnt seem to work with the latest su binary. Does anyone know if there is a way to disable the password requirement for stored certificates. It would be a useful feature to bake into some roms or even a new app that works with latest su.
I decomplied the apk for Keystore Unlocker but it was no help. I emailed the developer and asked if he would either update the app and make it paid (99 cents wouldnt be too much) or release the source for us to use for future projects.
Let me know if you guys have any ideas.
Same issue on HTC Incredible, Stock + Root ROM 2.3.4. Really annoying, anyone know a fix? My initial thinking is it's at kernel layer, as Hot Reboot doesn't cause issue but a "full" reboot does. Anybody have a suggestion on fix or workaround?
+1
Would love to bypass the credential storage. It literally decimates the battery trying to log into a credentialed WiFi (try/fail/try/fail) if you don't happen to notice that you haven't done the credential yet.
+1
I have mailed to the app's author, perhaps he has a solution.
Does anybody knows what exactly the app does? Is there a way by command line to activate the credential storage? (so it could be done in autostart)?
There are two possibilities to unlock the keystore. Both need to be run under UID=1000!
1) You have an AOSP based ROM, like Cyanogen:
There is a tool called "keystore_cli", which provides basic access to the keystore by commandline.
Simply run
Code:
su -c 'keystore_cli u <password>' 1000
to unlock it.
Other options are can be found in keystore.c:
Code:
static struct action {
int8_t (*run)();
int8_t code;
int8_t state;
uint32_t perm;
int lengths[MAX_PARAM];
} actions[] = {
{test, 't', 0, TEST, {0}},
{get, 'g', NO_ERROR, GET, {KEY_SIZE}},
{insert, 'i', NO_ERROR, INSERT, {KEY_SIZE, VALUE_SIZE}},
{delete, 'd', 0, DELETE, {KEY_SIZE}},
{exist, 'e', 0, EXIST, {KEY_SIZE}},
{saw, 's', 0, SAW, {KEY_SIZE}},
{reset, 'r', 0, RESET, {0}},
{password, 'p', 0, PASSWORD, {PASSWORD_SIZE, PASSWORD_SIZE}},
{lock, 'l', NO_ERROR, LOCK, {0}},
{unlock, 'u', LOCKED, UNLOCK, {PASSWORD_SIZE}},
{NULL, 0 , 0, 0, {0}},
};
I guess you can figure them out, if you want to.
2) You don't have the keystore_cli tool:
a) You might be able to use a keystore_cli binary from another rom
b) Use unix domain sockets to communicate with the keystore.
The socket is under /dev/socket/keystore.
To access this, you'd have to write a small c programm and use the socket(), write() syscalls.
Luckily. this is exactly what that "keystore unlocker" from the market does.
It comes with a small native executable located at
Code:
/data/data/ru.chunky.AutoKeystore/lib/libkeystorecmd-executable.so
which reads input to send to the socket from stdin.
The format is:
Code:
<code><length1><message1>...
Where <code> would be 'u' to unlock
<length> would be the length of the password as 16bit unsigned int
<message> would be the string representation of the password
In this example the password is "password", which is 8 characters long.
So the length would have to be \0000\0008 and the message to send to the socket
Code:
u\0000\0008password
Running
Code:
su -c "echo -e 'u\0000\0008password' | /data/data/ru.chunky.AutoKeystore/lib/libkeystorecmd-executable.so" 1000
should show a result of
Code:
1
in the commandline, if successful and the keystore should be unlocked.
it sounds brilliant!
Do you have any idea what is the problem with the app and actual su versions?
Awesome find man, shame is ICS fixed this bug. It just requires a pattern lock or pin lock. I wish we could find a workaround for this....

Nope, no idea.
I worked around it like this (cyanogenmod):
In /data/local/userinit.sh I put
Code:
#!/system/bin/sh
nohup /data/local/keystoreunlock_delayed.sh > /dev/null 2> /dev/null &
and the file /data/local/keystoreunlock_delayed.sh contains:
Code:
#!/system/bin/sh
sleep 60
su -c 'keystore_cli u <password>' 1000
The 60 second delay makes sure the phone has already initialized the keystore.
It's a bit of a diry way to do it, but this way it works without any android app.
To test this on my device, I made a file /data/keystoreunlock_delayed.sh
#!/system/bin/sh
su -c 'keystore_cli u <password>' 1000
and execute it within root explorer. But nothing happens!?
I tried su -c 'keystore_cli u <password>' 1000 in terminal Emulator, I got permission denied. I have to do a "su" before, without any parameters, then superuser asks for permission, and then the long command worked.

I forgot the permission 0755. It was 0555.
Can I download keystore_cli somewhere so I can use this script?
I have /system/bin/keystore but not keystore_cli on the rooted 2.3.4 OTA. Using HTC Incredible and would like to use this workaround script.
EDIT: I now realize this is in the Rezound forum. I found this thread by Google search but couldn't find much else on keystore_cli other than zip extract logs.
hm, I do not use a Rezound, too. I have a Desire.
Are you sure, this file is not an integral part of android?
I found one version on dropbox: https://www2.dropbox.com/s/cuu6hm8dvi3jxh5/BI/system/bin/keystore_cli
but I cannot say anything about this file. If it is genuine and ok.
What about asking in an Incredible subforum?
AutoKeystore fixed
I've just resolved "newer su" issue with ru.chunky.AutoKeystore and added password-less VPN Wizard there.
The following link gives a brief description about package installation process in android.
java,dzone,com/articles/depth-android-package-manager
I'm curious to know how the UID of an app is determined during its installation based on set the permissions present in its manifest file.
Also there is the platform.xml (in /frameworks/base/data/etc directory for 4.0 ICS Source code)file which contains list of permissions with gid associated with them. The description says
The following tags are associating low-level group IDs with permission names. By specifying such a mapping, you are saying that any application process granted the given permission will also be running with the given group ID attached to its process, so it can perform any filesystem (read, write, execute) operations allowed for that group.
In a similar way there is a list of high level permissions assigned to specific uid's as well.
My question is when an app is installed with permissions X,Y, Z how does its access specified is it from the mapping from this platform.xml
Also everytime the app is run does the mapping take place at every instant (that doesn't seem right from the initial design of android where the app permissions cannot be changed unless there is an update). So if that is the case where does it store saying this app should run with such and such access or such and such uid.
I hope I made my question clear, let me know if you need more information. I'm just trying to learn more on how the internals of the Android OS work.
Thanks
Well, a week into my Nexus 5 and the dates on backups got to me. "Was that the one before or after I pooched my phone?"
I was doing rough conversions at first, then convinced myself that there was a reasonably fixed offset between "real time" and what TWRP was labeling things. @helicopter88 let me know that there was a missing ability in the chip, so I looked for a run-time solution. Unfortunately, adjtimex wouldn't take a large enough offset.
Since the reasonably useless date stamps on backups were, well, reasonably useless, I did write a little script that converted the dates on the backups to something that matched my local time, given the offset.
Looks like @Dees_Troy has saved me a bunch of coding inside TWRP as there is a going-forward fix in the TWRP sources now. Since he found the magic file where the offset is stored, you don't have to try to "guess" it from looking at your clock and your phone's (though $ date && adb shell date will get you the information you need).
For those backups you already have, here's how you can get the dates and times fixed up on them.
Edit -- Shell scripts made up for on-phone use:
sh birthday.sh while on the phone will give you offset and your phone's birthday (Yes, Korean time, of course!)
Code:
[email protected]:/ # sh /data/media/0/twrp-dates-tool/birthday.sh <
1386550085
Mon Dec 9 09:48:05 KST 2013
sh spew-twrp-rename.sh /path/to/TWRP/BACKUPS will write the commands to move the directories to the terminal (stdout)
The "spew" script finds the offset itself.
It will rewrite both old (20th century) dates and current ones, but only time-shift the older ones.
It will also convert spaces in the file names to underscore characters.
See attached files (.txt added to allow upload)
No, there isn't a "zip" for this -- checking that the right things are being done with your backups before they can't be undone is important
Read on only if you want to do this using perl.
Now, you can adb pull /data/system/time/ to get two files, ats_1 and ats_2 that have the offset in milliseconds as a 64-bit unsigned integer. Pick one or the other, get the human-readable output trim off the last three digits, and there is your offset (within a second). Mine drifts a second each week or so, but hey, this is a lot closer than 1970 something!
Once you have the offset, this script will take a list of files and spit out the commands to rename them, if they match a TWRP-format date in the 1970s. (Edit $offset to match yours.)
Code:
#!/usr/bin/perl
use strict;
use Date::Parse;
use Date::Format;
my $offset = 1386550084; # Edit this to match your offset
my $line;
my ($year,$mo,$day,$h,$m,$s);
my $twrp_time;
my $new_time_string;
my $before;
my $after;
LINE:
while ( defined ( $line = <> ) ) {
chomp $line; chomp $line;
next LINE unless $line =~ m/((197\d)-(\d\d)-(\d\d)--(\d\d)-(\d\d)-(\d\d))/;
$before = $`; $after = $';
$twrp_time = str2time("$2/$3/$4 $5:$6:$7 GMT");
$new_time_string = time2str("%Y-%m-%d_%H%M%S%z", $twrp_time + $offset);
$before =~ s/ /_/g;
$after =~ s/ /_/g;
print "mv '$line' ${before}${new_time_string}${after}\n";
}
Output looks like
Code:
mv '1970-02-22--23-02-13 omni_hammerhead-userdebug 4.4.2 KOT49H 128' 2014-01-30_155017-0800_omni_hammerhead-userdebug_4.4.2_KOT49H_128

To be clear, the perl scripts run on something that has perl installed, like your laptop or desktop. The output runs just fine over adb shell to rename files on your phone. It also works just fine to rename the backup copies that you are keeping on your Mac, Linux, FreeBSD box. For Windows without Cygwin or similar, you'd want to change "mv" to "move"
Edit -- shell scripts for on-phone use added to lead post
So open in terminal on phone and run ?
