Removing system apk' $

[Jv90]

Altought we already know that removing this apk's from the system os would allow us to have a better performance on the tablet, this would be the following ones:

-Telephone.apk
-Telephony provider.apk
-Bluetooth.apk

But what about removing some other .apk's? Like hdmi.apk (for the express one model that doesnt come with hdmi) and few others?

So it would be great to know morw info is someone knows regarding it?

Warning: Too much deleting can lead to mistakes potentially bricking the device.

Use this information at your own risk. Can versus could versus do you really want to is subjective.

Before attempting any modifications ensure that the tablet can be factory reset "three finger method", obtain the "hwver", a current InfoTM Update Wrap (*.ius) file, download the InfoTM Update Wrap tools (IUW.exe) and know how to use them.

Thanks again cfrokit for your prompt response regarding my enquire,

I have been wondering if browser.apk could be deleted, because I noticed that when I run SkyFire and go to my task killer it always shows the browser.apk running too.
so if I can delete browser.apk I think my net experience might improve.

 

[Zippoku]

I can confirm it, you can rename or delete the browser.apk. Im using Opera Mini and Maxthon too !

What about hdmi services.apk? For the express model that comes whitout the hdmi port

There's a thread here somewhere called Essential Files that I started and has a list of files I renamed to see if it would break the system. I've since deleted all of those files and the system is running fine. I think the list CFR posted has a few additional ones that I'll have to peek at removing.

A few questions regarding the applications list above.

Camera.apk & Screenshot.apk - Since the TABEX7 doesn't have a camera, these can be removed right? What if you wanted to connect and external camera through the USB dongle, such as a webcam or even a digital camera? Would the camera.apk be needed?

I know Contacts.apk can be deleted, but ContactsProvider.apk has to remain. I don't really use my tab for email (would if I could tether to my Behold II) so I'm not worried to much about an address book. Has anyone else tried loading a different contacts list?

Can the Gallery.apk be deleted and replaced with something else?

I've removed both the FileManager and the HelenBrowser. I have EStrongs and RootExplorer, though both of those are in the data/app directory, I haven't tried moving them to the system/app directory. I did notice that after removing the originals, that EStrongs seemed to have lost it's ability to look at zip files, but I need to try that again to confirm.

The Wifi.apk can be removed and not affect Wifi abilities? Only thing about it is that you have to go to the settings screen? If that's the case I'll try removing it since I normally go to the settings screen anyhow.

Since I have the TABEX7 without the HDMI port, and I don't have a HD tv anyhow, I will try renaming the HDMIService.apk and post what happens. I know that I've had a few messages referencing 'HD' so it's possible that even without the HDMI port, the service is still needed. If it's needed in the way I think it is... I may have to reflash after renaming it. *crosses fingers*


Here's a question. With the Settings.apk and the SettingsProvider.apk, you say that you gain some features, but lose others. Can you be more specific? What's lost? What's gained?

I see, hmmmm..... What about theatermodeservices.apk?

Rrok007, sorry I try and recall if something has been posted and refer to that thread instead of repeating the same information. Using the Search Forum would has found your post http://www.androidtablets.net/forum/search.php?searchid=809510 where we discussed this topic

A few questions regarding the applications list above.

Camera.apk & Screenshot.apk - Since the TABEX7 doesn't have a camera, these can be removed right? What if you wanted to connect and external camera through the USB dongle, such as a webcam or even a digital camera? Would the camera.apk be needed?

My guess is these two applications are paired to provide the Screenshot functionality which is the "Camera icon" on the menu bar. If you don't plan on ever "taking a picture" of what's displayed on the tablets screen then they could be deleted.

I know Contacts.apk can be deleted, but ContactsProvider.apk has to remain. I don't really use my tab for email (would if I could tether to my Behold II) so I'm not worried to much about an address book. Has anyone else tried loading a different contacts list?

Can your Behold II host an Ad Hoc wifi connection? If so, there a patched file that will allow the tablet to see Ad Hoc networks thus allowing the tablet to obtain an IP and utilize the Host internet connection.

Can the Gallery.apk be deleted and replaced with something else?

Don't know.

I've removed both the FileManager and the HelenBrowser. I have EStrongs and RootExplorer, though both of those are in the data/app directory, I haven't tried moving them to the system/app directory. I did notice that after removing the originals, that EStrongs seemed to have lost it's ability to look at zip files, but I need to try that again to confirm.

I noticed this as well with RootExplorer and traced it back to the microSD card. Without an SD card in the tablet, files could not be unpacked thus viewed. Once a properly formatted SD card was inserted the functionality returned.

The Wifi.apk can be removed and not affect Wifi abilities? Only thing about it is that you have to go to the settings screen? If that's the case I'll try removing it since I normally go to the settings screen anyhow.

To test, just add to .bak file extension to the existing application without removing it and test to confirm before deleting.

Since I have the TABEX7 without the HDMI port, and I don't have a HD tv anyhow, I will try renaming the HDMIService.apk and post what happens. I know that I've had a few messages referencing 'HD' so it's possible that even without the HDMI port, the service is still needed. If it's needed in the way I think it is... I may have to reflash after renaming it. *crosses fingers*

Either rename or add the .bak file extension to test. Several posts discuss clearing /data/dalvik-cache folder as it maintains some application information. Once the folder is deleted it is rebuilt on the next reboot. I first saw this instruction in adding Google Market, not sure if it pertains but it makes sense that an application may need to be cleaned up if manually deleted.

Here's a question. With the Settings.apk and the SettingsProvider.apk, you say that you gain some features, but lose others. Can you be more specific? What's lost? What's gained?

It's been a while since that was tested while searching for an update method. What I recall was the System Update no longer pointed to infoTM but a generic method which failed. Phone settings appeared but since this is a tablet they were useless. You could toggle Mock Locations and some other development settings. If time permits load the SDK and create a virtual device and view the Settings to see all of the common options. infoTM has removed or blocked access to ones that either don't pertain or they don't wish to code to support.

I see, hmmmm..... What about theatermodeservices.apk?

Good question, does it go with HDMI or is it related to media such as a photo slide show or movie player. Try adding the file extension .bak without deleting the application to test.

As always, if you can "three finger" factory reset anything deleted will be restored to factory after reset since we don't have a custom update file. All of this investigation will make it easier to decide what or what not to include in a custom ROM for performance or functionality.

ok i had a problem with my archos 7 home tablet i use to use this tablet normally and then i said let me upgrade the firmware to android gengerbeard 2.2.1 now im having problem with the tablet im not happy with the android i wanna take it back to the old firmware and i can't when im connecting the tablet to a PC its not showing me any message as "MOUNT" i try'd everything no matter what the PC its not seeing the tablet please guys help

 

[Jv90]

hmmm; but you are in a Sylvania tablet forum, not an Archos forum, and I truly understand what you are asking for, on our model we can do it, cause we already have the knowledge and os files to burn whatever image we want; but on the Archos? I really don't know, there has to be some way for sure
