LG encrypted apps can't be loaded #27

chris1000 · 2015-03-09T01:40:00Z

When you install any version of xposed on lg g3 lollipop it cause several apps to crash. These apps are LGSmartCover and Wether applications. You cannot uninstall LGSmartCover because it causes fc's.

rovo89 · 2015-03-09T07:57:27Z

Please provide logs of the crashes, otherwise I don't have any chance of analysing or even fixing them.

Some logs are here: http://forum.xda-developers.com/lg-g3/general/how-to-xposed-running-properly-stock-t3030261
Thanks for You work !

nobless · 2015-03-12T00:26:41Z

chris100 we know this, but what if we use circle case ?

nobless · 2015-03-12T07:59:45Z

I know that we can just delete smartcase and weather, but im using smartcase :)

rovo89 · 2015-03-12T16:18:37Z

Sorry, I don't have time to look into this at the moment... Maybe someone else has enough technical knowledge to check the logs for the root cause? The ClassNotFoundException for SmartCoverViewManagerService seems to be a good start, maybe there are other lines before that (verifier rejecting the class or something like that). Also, is that class even existing in /system/priv-app/LGCover/LGCover.apk?

chris1000 · 2015-03-12T16:23:15Z

Try sending a log I can try to help if not I will ask for help on xda

The root cause is that some LG apps are encrypted. Both dex and oat are protected(AES-CBC). LG art libs are slightly differents than AOSP(so dex2oat is) ones,anyway almost all the code to handle the protection is placed in another lib(liblgalmond)

rovo89 · 2015-04-07T17:44:53Z

Do you have any reference with further details on this? I don't really expect that I can add support for such apps, but it would be good to know.

P-Toti · 2015-04-09T19:25:16Z

Actually the protection isn't anything hard to understand(and there are at least 2 ways to obtain a clear dex) but i agree you shouldn't add the support for such apps.(unless you agree to create a closed-source fork). LG just encrypted 2 proprietary apps and i think they probably had very good reasons for that(even if i really couldn't find one). That's why i chosen to not release the apps after decrypting them(i really don't want LG to be mad at me). I can send to your email further details,including some explanations about the protection,the lib,a clear and the relative encrypted dex if you are interested.

ghost · 2015-04-26T23:47:09Z

Has this issue been addressed on newest release? I know this is not the biggest issue on your plate but any update would be appreciated!

pylerSM · 2015-05-01T12:50:50Z

Even LG modifies ART? If every OEM did it, it would be death of Xposed.

Zorastris · 2015-06-03T11:35:06Z

Any updates on this issue? Can any one be of assistance please? Thanks.

kevinkhill · 2015-06-03T23:50:16Z

I am also curious if there is any hope for us G3 owners of circle cases to be able to have xposed and smart cover working together? I don't know much about android development, but I can help test or debug if possible.

rovo89 · 2015-06-04T22:22:09Z

I have currently no plans on adding support for encrypted apps (mostly because of limited time). However, Xposed is open-source, so if someone wants to try and create a proof-of-concept that can handle such apps, I will obviously consider integrating it.

kevinkhill · 2015-06-04T22:30:56Z

Ahhh, I see, I didn't realize that was the reason why it didn't work. I would like to help, but I wouldn't even know where to start. Thank you very much for all that you have done and I'll just keep patiently waiting for someone more skilled than me to hopefully make a fix.

@lgg3helpme

LGSmartCover is an encrypted app and is incompatible with xposed. You have 3 choices:

Remove LGSmartCover completely
Freeze LGSmartCover
Don't use xposed

I recommend the 2nd one.

chris1000 · 2015-07-02T04:38:21Z

I just took it out of my ROM that way my users don't have to worry....

Can someone please upload the files related to the apps that cannot be used and the encryption library? I think that would be:

/system/priv-app/LGCover
/system/app/LGWeather
/system/app/LGWeatherService
/system/lib/liblgalmond.so
/system/build.prop (just for reference)

rovo89 · 2015-08-02T13:58:33Z

Anyone here who could test this? http://forum.xda-developers.com/lg-g3/general/how-to-xposed-running-properly-stock-t3030261/post62151398

rovo89 · 2015-08-03T13:09:59Z

@suljo94 Unfortunately, the XDA thread is closed now. So everything works fine after deleting the Dalvik cache? Nothing else required? If yes, I'll release an official update with the change.

Zackptg5 · 2015-08-03T15:05:16Z

@rovo89 Sorry, was out of town. Here's the files you requested: http://www.4shared.com/zip/5IjAoJLDba/LG_Encrypted_Apps.html

The lib file was where you said it would be; I have the verizon variant lg g2. These are all stock files as I flashed stock lollipop to make this as vanilla as possible. Currently testing the xposed version you put in the thread, will update when It's booted (so far so good)

Edit: Booted fine, no force closes, installer says xposed is installed and working but when attempting to get logs from the installer, gives read error. So I got logs from terminal and catlog:
http://www.4shared.com/zip/sZUBO6fuce/v69_Logs.html

Hopefully one of them will have what you need. Thanks!

rovo89 · 2015-08-03T16:21:57Z

As long as there are no force closes and the LG apps work fine, I don't think I'll need any further logs. The Xposed logs might be available after another reboot.

smiledexter · 2015-08-03T16:47:19Z

com.lge.filemanager work fine with v69 test1 version, thanks.

rovo89 · 2015-08-07T07:24:37Z

The commit only adds support for encrypted .dex files. However, some ROMs have encrypted .odex files instead, which will need a different way of decryption. I'm almost done with this and will probably upload a test build this evening (in ~9 hours from now). If anyone is available for testing at that time, it would be good, as I won't have time to work on Xposed in the next few day.

alex-necula · 2015-08-07T07:34:00Z

@rovo89 i'm available for testing at almost anytime. Can' t wait for that:)

steffenbakke · 2015-08-07T12:56:43Z

I'm staying tuned for this !

rovo89 · 2015-08-07T17:57:45Z

@cretu01 @steffenbakke Could you test this please? https://www.dropbox.com/s/yp4uwdfau4zou5z/xposed-v70-sdk21-arm-test1.zip?dl=0
Again, it would be helpful to clear the Dalvik cache, just in case...

alex-necula · 2015-08-07T18:08:51Z

This is working flawlessly, no FCs for cover, weather etc. i didn't wipe dalvik cache as lgcover and weather weren't present before in system (renamed those as .bak from the beginning). although, easyhome was present (gave FC only when enabled) and it is working, too! Do you need further logs if no errors are present?

rovo89 · 2015-08-07T18:11:26Z

Thanks for testing it so fast! :) No further logs required if everything's fine.
I'll give @steffenbakke some more time for testing though.

fishears · 2015-08-07T18:30:03Z

Tested on G Pad 8.3 (v500) with stock 5.0.2 and Weather is now fully working. This device doesn't have LGCover, weather was the only problem. Thank you so much.

steffenbakke · 2015-08-07T18:44:19Z

Just flashed it and seems everything is running as it should. Thanks for fixing it!

Hello,

So reading this thread I understand that the LG encryption issue has been fixed :-)
How/where can I get this build to install Xposed on my LG G3?

Thanks a lot

LG has encrypted a few apps with their DRM implementation. Those apps can usually not be loaded. Fortunately, the decryption takes place in a separate library called liblgalmond.so. Xposed now uses this library if available to check if a dex file (usually located in a ZIP archive) is encrypted, and if yes, triggers the in-place decryption of the file before initializing it. For precompiled/odex files, a different way of decrypting is required. Similar to dex files, the decryption can also be done on the fly when the file is loaded. Fixes rovo89/Xposed#27. Conflicts: runtime/dex_file.cc
