[HOWTO] Install Latest WaveSecure in ROM

I found that [email protected]'s ROM had a good idea of adding WaveSecure to the system partition (preventing listing in the My Downloads part of market, and preventing uninstallation through normal means), but his version is slightly out of date now (latest version is 3.0.0.43)
As a result, I set about finding a means to install WaveSecure to ROM myself. Here are my findings for anyone interested in doing the same.
Install the latest version from the market (3.0.0.43 at this time). Now use adb pull to get it off the device onto your pc
Code:
adb pull /data/app/com.wsandroid.apk D:\com.wsandroid.apk
Now open Market back up from the menu, go to My Downloads, and choose Wavesecure Mobile Security Beta and uninstall it for just now (to get it off the data/A2SD location that normal apps are stored in) - thanks, my-space!
Then push the saved apk to the system partition after a remount (to make it read/write)
Code:
adb remount
Code:
adb push D:\com.wsandroid.apk /system/app/com.wsandroid.apk
Then set it all up as usual (will appear in apps list immediately)
and remount system as read only again
Code:
adb remount
And that seems to be it so far. Remember to change the D:\com.wsandroid.apk path to whatever you actually used.
Let me know if anyone finds any problems with this, but I've done it and, fingers crossed, it's worked OK for me.
Obviously, this is only for root users, and there are no guarantees for this.
Couple of questions that might need looked into -
- Do settings carry across after a wipe (as Paul claims Modaco's version does. I've never tried it so can't confirm)
- Is there any disadvantage to using this method? (I guess this is all Modaco's update.zip does, but I don't know)

Oops! Knew I'd forget something, as I always seem prone to do. Well spotted, and OP corrected.
Thanks

No worries I got a bit confused when i pushed it back onto the phone and was still in my downloads...

I've rooted my phone already but whenever i try to use the command adb remount I get "remount failed: operation not permitted". Suggestions?

I see more and more often, redundant threads.
What How-to will you post next time? How to change backlight settings?
You're pointlessly spamming the board.

I can't say i agree with the 'pointlessly spamming the board' comment, but i would have thought this would at least be better in the applications and themes subforum rather than in development.
Don't forget that an awful lot of android users (and more recently all HTC devices) are more and more 'newbs' and need stuff like this.
While this is good and provides info that people like that need (and myself cos i'm crap at adb and stuff like that so wouldn't have had a clue how to do this previously), maybe the development forum is not the best place for it....

I'm guessing one won't be notified via Market if there's an update available if you push an app to /system/app/, right?

You won't be notified, correct

If anybody doesn't already know, WaveSecure have started hosting update.zip files. This means it's now easy to update your "baked-in" version of WaveSecure without much messing around.
https://www.wavesecure.com/installations/update.zip
Download the file, save it to your SD card, reboot into the recovery console and choose the option to apply an update.zip file.
Voila! Your version of WaveSecure will be updated to the very latest version

That's really awesome! Thanks for the tip!
Just a question of curiosity: If I push an app to /system/app/ and then issue the rm-command to remove its apk, won't there be lying a bunch of files associated with the program and with absolutely no function, since the app itself is removed? How do I know the name of these files and where they are located for removal?

I'm a bit confused by that question. My understanding (which may be incorrect but from what I've seen of the "guts of a ROM" appears to be the case) is that the applications reside in the apk files, they are not extracted. If you list the content of any of the app folders (/system/app, /data/app or /data/app-private) then all you get is a bunch of apk files (and some odex files). So when you 'push' an apk to the phone, that application is then "installed", when you rm/remove an application, you do so by removing the apk.

if you remove the apk you have left something in /data/dalvik-cache. wiping the dalvik-cache every now and then helps reclaiming that space, though it is not much.
the app settings and data are stored in /data/data, you could delete the files manually by checking their names (no idea if/what convention the names follow), imho not worth the trouble as it is only a few kb.
odex files aren't created if you don't do in a PITA process manually. don't worry about them, don't touch them, then you're good. odex files are only for system apps.

I bought a used phone and it had WaveSecure already installed. I couldn't find it in the applications list to uninstall, so I did a factory reset on the phone. The application was still there and it still didn't show up in the applications list.
I have the Superuser Permissions application, so someone must have rooted it.
Is there any way to uninstall this?

""Just (re)flash a ROM................""

I just noticed that WaveSecure now points to this post for instructions to install as system application, and I am not sure that the update.zip maintained with them is up-to-date.
However, you can now select to download the .apk directly to your PC thus eliminating the first Market step in this guide.

I believe it is kept up to date, as VillainROM kitchen uses it as a source for the WaveSecure app (fetched each night to keep it up-to-date).
I've certainly never had any problems with it.

Excellent guide Pulser,... I should really reinstall Wavesecure now Im not using a MoDacO Custom ROM. Nice one bruv.

Found this to be helpful.
https://www.wavesecure.com/blog/how-to-make-wavesecure-hard-reset-proof.aspx

I just did a search in the Market fro 'wavesecure' and two things popped up WaveSecure and WaveSecure UninstallProtection Add-on which needs to be uninstalled before WaveSecure and if the add-on is uninstalled it is supposed to lock the phone. (all this is in the description I have yet to try)

[APP] Softbankメール(mail) v1.5

Hi,
Since the release of the latest application (v1.6) a lot of users have been upset about the horrible downgrade in software.
It seems that Softbank has still not hired any native English speakers.....
Anyway I'm not here to rant I'll just post the files for v1.5 since a lot of people were asking where they could find a copy for themselves.
I pulled both of these files out of a backup I stored onto my SD card using MyBackupPro. Not sure what the zip file is for, but the APK is there. Maybe somebody could clear that up for me as well.
Zip file
APK
As far as I know there is two ways to get this installed (there may be many other ways).
1. adb push the apk or
2. download MyBackup and do a quick backup of some apps you have installed already. download both of these files and paste them into the directory where MyBackup stores the backups for apps. run MyBackup and choose to restore the Softbank Mail app.
cheers.

Hi, after reading your post I discovered my version of SoftBank Mail is 1.0 but I've never received an update notification - probably because I'm not in Japan.
EDIT: Apparently it's because the version you've uploaded is designed for non-Japanese models and it's incompatible with mine.
I tried simply downloading the app and running a standard installation - it did install, but when I tried to launch it, I got a notification that it cannot be used on my device (Galapagos 005SH).
EDIT: The MyBackup method does not work because simply adding the files in the directory where the backed up APKs are doesn't automatically lead to the new APK(s) showing up in the list of available apps to restore - it's because the information is also written to a dedicated file (MBP extension I think it was). Perhaps that can be edited but...

[Q] Can't find or re-install HtcFacebook app

Hi,
I am running Virtuous Sense 2.0.0, but since installing that MOD, I can't find the HtcFacebook App any more in my system.
Somehow HTC Facebook it must be still in the system, because the APK is in the system/app folder and I can add an account for HTC Facebook in the settings/accounts section. And that account then also syncs my Facebook-Contacts into the Contacts/People App.
But I can't find the Icon anywhere and I can't use/start the application, nor re-install it by any means.
To make things even weirder, the downloads app just told me, that it downloaded an update of 410kb dated 22.07.11
When I try to install that, it says, that this is a System Application, and when I confirm it lists the permission requests and when I hit "install" the progress bar comes up for a second followed by "application not installed".
When I try to do it manually, it fails too:
I opened the Terminal, typed in su to get root permissions. I went to /system/app and tried to install the HtcFacebook.apk from there typing
pm install -r HtcFacebook.apk
It fails with:
Failure [INSTALL_PARSE_FAILED_NO_CERTIFICATES]
when I go to /sdcard/downloads and try the same with the downloaded HtcFacebook.apk I get the same Error-Message.
I also tried ASTRO and FileExplorer in both directories with the same result.
Also using ADB commands failed.
Googling the error messages didn't get me any further than what I mentioned above. Now I am quite helpless...
Any help appreciated.

Nobody? Everybody who is running Virtuous Sense 2.0.0 is having no problems with the HtcFacebook App?

HTCFacebook is just the integrated facebook thing. If you want the facebook app back, you'll have to go to the market and find Facebook.
Here is a link to the market page, which you can install it from
-Nipqer

I know there is another Facebook App in the market available. But it does not have the same features as the HTC version. Before I installed Virtuous Sense 2.0.0 my original Stock ROM had an HTC Facebook App and after I downloaded and installed the regular Facebook App I had TWO Facebook Apps available.
Now, after flashing the Virtuous Sense ROM, I am stuck with only the one from the Market. But for several reasons, I want to have the HTC variant back. And there must be a way, since even the Downloads-App is telling me, that an update for it is available:
-------------------------
HtcFacebook.apk
synergy-base.googlecode.com
Ready 410 KB 22.07.11
-------------------------
Unfortunately trying to install the update just produces an error.
Am I really the only one missing the HTC Facebook App and the respective Icon to access it?
Tronar

Instead of installing it do this
cd to where ever your adb is located (mine is c:/androidsdk/platform-tools)
place the HTCfacebook.apk you want in that folder and type this:
Code:
adb remount
adb push HTCfacebook.apk /system/app/
adb reboot
Should replace the current HTCfacebook.apk and you will possible get your facebook app back.

Thank you for the tip. I tried that. I copied the new HtcFacebook.apk from the /sdcard/downloads/ location to /system/app/ using Root-Explorer
I also set the correct rights (rw-r--r-- like all the other .apk-Files in the same folder) and the correct ownership (root and root)
Then I rebooted, but nothing changed.
My feeling is, that I need to Install the .apk-File, not just drop it someplace.

As mentioned in my first post, I tried all kinds of ADB commands.
Code:
adb install HtcFacebook.apk
was one of them. All install attemps fail with the error message mentioned above.
I tried it again right now, here is the result:
Code:
adb install HtcFacebook.apk
1299 KB/s (499112 bytes in 0.375s)
pkg: /data/local/tmp/HtcFacebook.apk
Failure [INSTALL_PARSE_FAILED_NO_CERTIFICATES]
My guess is, that somehow the certificate system is a little buggy with Virtuous Sense 2.0.0. Maybe the signing of the packages is therefore not recognized.
I get the same Error Message when trying to re-install the HtcFacebook.apk that was already in /system/app. I mean that package should be signed correctly, since it came with the ROM, shouldn't it?

According to HTC:
What’s the difference between Facebook app and Facebook for HTC Sense?
Facebook for HTC Sense is not a standalone app. It is integrated in People, Friend Stream, Gallery, and Calendar to give you up-to-date information about your Facebook contacts (their status updates, shared links, and photos) in these apps.
The Facebook app is a standalone app. Use this app to do most of the things that you would do when you’re using your computer’s web browser to access your Facebook account, such as adding a friend and sending Facebook messages.
The two do not share the same login credentials. Signing in to Facebook for HTC Sense does not sign you in to the Facebook app and vice versa. If you want to use the same Facebook account for both, you’ll have to sign in to both using the same login credentials.
Note: If you have more than one Facebook account, you may sign in to the Facebook app using your second account, since the Facebook app does not share the same login credentials as Facebook for HTC Sense.

I hope that clears everything up for you. I used to think they were two different applications that did the same thing, but they are actually two separate things. The HTC part only integrates Facebook into the rest of the phone environment.

Wow, that is weird. Thanx for digging up that information. It must be new, because I swear with the old Stock ROM I had TWO Facebook-Applications on my HTC Desire Z. Maybe they changed it for the Gingerbread 2.3 Upgrade?
I noticed one effect after copying the new HtcFacebook.apk into the /system/app folder: I had lost all my Facebook-Contacts in the Contacts app and had to re-add the Htc Facebook Account and refill the Login & Password Fields in Settings->Accounts & Synchronization to bring them back.
Nonetheless, all of this does not explain, why the automatic Update of the HtcFacebook.apk from the Downloads-app just fails to install. Is this a bug in the Downloads-App, because System-Apps are never supposed to be installed automatically? Or does this just apply for the HtcFacebook.apk? I can't test it out with other apps, because the HtcFacebook.apk is the only one, that every appeared in the Downloads-App so far.

Same problem with Facebook fro HTC Sense
I am experiencing the same problem after installing a new ROM to my HTC Desire.
This ROM works well and brings Android 2.3.3 and HTC Sense 2.1 yet I cannot find neither the "Facebook" app nor the "Facebook for HTC Sense" widget.
Each time I download the Facebook app from the market and launch it I get an error message telling me that "processocom.facebook.katana" got interrupted and when I try to launch the "HtcFacebook.apk" I get the message "Application not installed".
I cannot sort it out...

To install the HTC Facebook could you not just flash the rom over the top again?

What did you do when you flashed onto this new ROM? Which ROM is it, and have you used it previously? Did you flash a ROM cleaner of some sort?

I installed this ROM: AceSMod007 taken from http://forum.xda-developers.com/showthread.php?t=1113070
It is the first time I use this one (previously I tried MIUI, LeeDroid, InsertCoin)
I followed all instructions... I mean I wiped data, cache etc etc. then I installed the ROM and performed a Titanium Backup restore.
Yet when I was checking out the Facebook application I noticed those problems that I highlighted and I started looking for a possible cause and solution to that.

When you did the Titanium restore, did you restore system apps or system data?

I restored both them.
Now I tried delating the account under Settings->Account Sync and installing and de-installing the App from the market.
Then I recreated the account into Settings and the synchronization seems to work.
On FriendStream widget now I see FB updates too.
I tried to put on the FB widget (the Facebook for HTC Sense interface seems to be missing yet).
This looks like being hung on "Updating states..." although it takes me to the app when I click on it.

have you tried extracting the .apk file from the rom itself and installing?
if the rom is a zip file (it most probably is), the apks are usually found in one of the folders (maybe /data). extract the zip and look for the directory where all the apks are stored, and perhaps you can re-install just the programs you want.
hope this works.

I previously tried installing HtcFacebook.apk but as a result I got a message "Application not installed"
Now the standard Android FB widget seems to work too...
No traces of Facebook for HTC Sense though
Weird...

How do you launch the HtcFacebook.apk? Do you still have an icon for it? Because I don't!
And as dkmurphys found out, according to HTC, they seem to have intentionally given up their HtcFacebook App with the latest Stock-ROM update to Gingerbread 2.3.3
So HtcFacebook.apk is only still showing in the list of Apks to provide the background services for the HTC Widgets, like the FriendStream Widget for example.

[Solved] Any way to access an apk file immediately after flashing?

I'm not sure if this is possible as ICS has no built in file manager, but is there anywhere I can put an apk file that it would be accessible without one? Specifically I want to be able to open an apk to install a file manager as the first thing I do after flashing a rom, to avoid needing to go through the market.
I thought maybe I could leave it in sdcard/download but it seems like the downloads program is blind to anything in that folder that wasn't officially "downloaded". (I suppose I could upload one to my dropbox and download it via the browser, if there are no viable options). Also made a few stabs at getting the gallery program to show one but it seems to filter out anything that's not a picture or video.
Any ideas for places to stick an apk and get one of the stock programs to let me open it?

maybe email it to yourself?
but you would have to log into the email app to do that
but there isnt really anyway to access the file without a file explorer

Open your favourite rom zip, add your apk to /system/app, save the zip, push that zip to the phone, flash.

Yeah in general I'm trying to cut out the step of signing into anything and just restoring my apps from a backup before I need to cancel automatic restore functions (which I do want on and running once I do my own initial run of things).

I'm guessing this comes with the consequence of raising any apk added in this manner to system app level? Not that I distrust the apps I'd have in mind for this to do anything malicious themselves, but is there any danger of opening security holes by elevating apps not designed to be system apps?

What I've done many times is just enabling Air Plane as soon as I can after flashing a ROM. That's way I can install any apk I want.
Hope it helps.

Hmm but then what is your method for getting to that apk? If you do it over wifi that seems to defeat the point, no?
Personally I've found that it works just fine to uncheck the boxes for recovery syncing during the setup process, and then just re-enabling them later in settings. (Alternately, not signing into my google account at all until I've performed a backup). That way even if I end up signing into the market to download a recovery app, it doesn't automatically try to re-download everything else on its own.
I'm starting to think that my dropbox solution will be the cleanest, as it'll be a simple step of opening the browser and downloading a single apk every time at the same link.
I bet that the inclusion of a basic file explorer will be one of those headline items in a future android release. A nice basic functionality that the bloggers can rehash to death before anything actually hits.

Download the file manager apk over wifi and install the APK via download manager.
I do it all the time with Chinese android tablets with no market access.
Or Bluetooth it from another device.
Or just use the market

Transfer by USB from my laptop.

Is there a way to do that in which the device will launch the apk you move over? When I copy files over usb, it only ever puts them into whatever directory, and I need a file explorer to interact with them on the phone. And then I'm back to square one, as far as this particular task is concerned (once things are up and running I just use the LAN option in ES file explorer and it's as convenient as could be).

you have the apk in your computer right?
connect the phone to pc, and use adb to install
'adb install <apk_file_name.apk>'

Ah. I haven't used adb since I first unlocked/rooted a few months ago. Guess it probably pays to be a little familiar with those tools; they don't even occur to me when problem solving these days.

mark thread as solved then, if that solved it

Well a completely in-phone solution would still be nice, but I guess if there were any of those they'd have come up by now.
I'll probably use abd if I'm actively working at my computer and a dropbox download otherwise.

Cann't install apps anymore on Pixel 2XL

Hello all,
I cann't find a solution to install apps in sideload on my Pixel 2XL.
It was after flashing version 10 in the beginning of september.
After a lot of trying I give up and hope someone else here can help me.
My Pixel 2XL is unlocked but not rooted.
Normally I do the sideload by transfer an apk to my dropbox. After that I start it up and do what the system tells me.
Nowadays I got a return of a message in dropbox that -it is impossible to open the apk and download an app to open the apk-.
After that I download the apk to my download folder to try again. Then, when trying to startup, I get a popup with the name off the apk, the version nr, the size and packagename.
There is also a button to view apk content. When I push that button the right folders of the apk are indeed visible.
There are also 3 options. One to install, one to go to playstore and one to stop further actions and go back.
When I try to use the button install the result is that nothing happened, no signal, no message from the system, no popup, really nothing.
You all know that this is not what I want. I just want to install the apk. I have tried it with a few other apk's with the same results. :crying:
Before the last OTA upgrade to android 10 it was normal to install with these methods.
Thanks for who can helping me and others for trying to help me.
Greetings.

Have you enabled install apps from unknown sources? You'll also need to enable apps to install apps from what I can see in android 10. If you pull up an apps indignation you can expand the options and there will be an option to allow it to install apps, which Dropbox may need. The first one needs to be enabled to install apks from the download folder.

I did all these settings before.
Now I tried to open another filemanager (Google Files) and that did the job.
I don't know why installing in dropbox or installing in es file explorer doesn't do the same with equal settings.
Maybe an idea to uninstall and re-install these apps?
Anyway, a lot of thanks for your answer.

Android 10, install from unknown sources is like an app permission now, you have to grant it to things like chrome (download apk and install) and file managers rather than a global setting for phone. Safer as you trust an app o do it rather than letting some malware in background filling your phone with crap.

Maybe an idea to uninstall and re-install these apps?

Uninstalling and reinstalling will not work, as I've done that with my modded version of ES File Explorer. This is a change in Android itself.
Go to Settings > Apps & Notifications > Special App Access > Install Unknown Apps. A list of apps will appear. Select an app and toggle the switch.
NOTE: Dropbox is on the list, but at least on my device my modded version of ES File Explorer is not.
