[REF][ServiceMode] How to make your Samsung perform dog tricks

[aguaz]

No, because CM dev people doesn't seem to know how the SM works and have messed up some of the standard functionality when it come to SM related items and "secret codes". Unfortunayely this is not only true for CM, but also most other AOSP based ROMs. SM is usually provided by a (java) wrapper application to send OEM commands to the baseband where the SM is actually running. So, you can try to install a copy of the Factory and Service related apps, as found on the stock rom of your device (using the same API version).

Is CyanogenMod/android_packages_apps_SamsungServiceMode related to this? And if not what is it?

My service menu is completely blank... any way to fix it?

Solved, it was due to com.sec.phone which was disabled by me.

Yes, it seem to be. Thank you very much!

Hi all,
Is there any way I can reset all the changes done in the ServiceMode menu?

I guess Factory Reset will do that. Not sure if anything else will reset too... :highfive:

Factory reset doesn't work. Any other ideas?

I have exactly the same problem after upgrading to 4.4.2, so don't worry, it is Samsung policy. Beside using Shortcut Master app to launch it, here is another workaround:In the Shortcut Master app, open Menu > Search and enter 'usbsettings.usbsettings' to search. Tap on the search result to launch, you can also create shortcut for it.

@vndnguyen : Please stop spamming my threads. I've already removed some of your annoying spam posts, trying to promote your app, and you insist re-posting the same garbage. In this particular case your answer have little to do with the quoted question/issue, and does not contribute to any further understanding. So stay away please!

Hi there, I got a Samsung SM-G906K Galaxy S5 model. Up until the latest stock update (4.4.2 rooted) I used to be able to run the code *#0808# no problem. Now it doesn't work anymore.

You may consider de-compiling the ServiceMode related apps as mentioned in OP and in my other thread. Almost all the secret codes are in there. In your case they've probably blocked direct code dialing, and you may need to enable/disable those other system properties (getprop) mentioned. Common problem is that code exists from command line via "am ... " but not from dialer. Sometimes it's just a matter of re-arranging the "*#"'s or add another.

See this thread.

A easy way to get into this woth out needing to q then 0000. This works on all samsung phones and maybe others stopped working on my sgs4 after mf9 update but my s3 and note 4 and sgs5 are still able to do this method. So just go to system menu and scroll or tap till you find activate this device/ self service let it run through once it shows your plan info hit menu or three dots then pick pst and bam then your in iothiddenmenu pick test mode and your in. Do note tho that sometimes it can take a few minutes for self service to load up. If you click pst and nothing happeneds then you need to downgrade for it to work only seen on sgs4 running into this problem the non spark one.

Hit thanks of this helped anyone out.

Because you don't understand how SM works. SM is located in the baseband FW and the way to access it, is through a wrapper application. If this wrapper application is not present or is using other "codes", you'll not get in. Which is why I don't wanna use CM, and always try to stay close to stock.

I've now built cm-11.0 with CyanogenMod/android_packages_apps_SamsungServiceMode.
The app opens up dialing *#*#0011#*#* (yes, that's two "*#" each). However the app stays blank. Also entering Input --> "Q" and Input --> "0000" as suggested elsewhere has no effect.
Any further ideas?


Are the settings btw stored in FW and survive a reboot? Alternatively I'm thinking about a Stock/CustomROM dual boot where you tweak SM settings in stock, then reboot into CustomROM with settings (hopefully) preserved.

Very nice, but you have to tell me more what device you're using. If it is a Samsung you can download the FW, extract it and reverse the Phone and Service related apps and have a look for the correct OEM_HOOK_RAW (IPC?) sequence that navigates to that SM implementation.

Are you or that code on github by any chance?

 

[E:V:A]

One more thing. It is important to start on a freshly rebooted phone, AND you HAVE to hit the BACK button before the input sequence. I have no idea why, just that it doesn't work without hitting back button first, at least for me. Oh, I also noticed that you can combine the Q and the zeros as "Q0000".

@aguaz: Yes, that code is on GitHub HERE. You probably need to change at least some of the OEM commands in OemCommands.java. And check that the
getEnterServiceModeData() is sending the right code. The way to check is in the stock APK.

Yes, that's what I took building cm-11.0 for GT-i9192

I see, why would it be easy.
So the cm app is more of a template for SM or was it written for a specific device only?

I never worked on CM or any devices with it, so I have no idea. I just know that when it comes to this kind of low level stuff, CM is rarely working and nobody know why or cares to document or inform anyone else about it.
