Tweaks for the MID9742 Stock ROM

Throughout the past few months I have been working on various tweaks to solve issues related to the stock ROMs. The main reason for this was to actively discourage noobs from trying to install Livesuite and bricking their tablets with that software. Not being overly familiar with Edify scripting it took me a while to figure out just how to get some of these tweaks onto the tablet without having the tablet fail to boot. With the help of Vampirefo making Clockworkmod recovery images available for download and install I can now present to you flashable zips for all the tweaks I have provided.

To install these tweaks, at a minimum, Busybox must be installed beforehand. The easiest way to get Busybox is by heading to the Play Store and installing it from there. It is possible that other app stores such as 1Mobile will have it, but that will require a bit of searching.

These tweaks have been tested on a 9742 and found to be working. The Google Play Compatibility tweaks should work for any Generation 3 tablet with an Allwinner CPU and Clockworkmod installed. The Framework tweaks are only supported on the 9742. They may function on other Generation 3 tablets, however all tweaks applied here are done at your own risk. Neither I nor Androidtablets.net will be held responsible for any issues that may occur in using these tweaks.

Google Play Compatibility Tweaks: These tweaks consist of the build.prop from the 9742 Mobiz ROM and the XML files that were included in that ROM. Combined, these files will allow the end user to download virtually any app. In addition, this should fix the limitation of not being able to properly access \mnt\sdcard.

Framework Tweaks: These tweaks consist of activating the network location service and providing an updated battery indicator in the status bar that counts down battery percentages in increments of one percent. There are two files, depending on which type of battery icon is desired in the status bar. Select the battery style you like best, and download it.

I have also taken the liberty of combining both tweaks into a single flashable zip which will apply everything in one fell swoop. Select the battery style you like best and download.

As of the date of this post, the following will occur:

1. The tweaks zip in my signature will no longer be available. The link will redirect to this post instead.
2. The framework-res.apk files I made available in the How To Manually Replace framework-res.apk On Stock ROMs thread will remain available for anyone not wishing to change their battery icon. A link to this thread will be provided there.

 

Vampirefo ported the Mobiz ROM to the 9742. The build.prop and permissions files were pulled from that ROM and it uses a Samsung GT-I9100 (Galaxy S II, if I recall) fingerprint. I couldn't tell you whether it will fix your problem or not, but it did fix mine in that I now can download TuneIn Radio without a problem.

If you choose to apply the Compatibility Fix, you'll need to force close both the Play Store and the Google Services Framework, then wipe the data and cache for both. Reboot, then access the Play Store. If the Play Store throws up an error the first time you try accessing it, simply close out of it, remove it from the list of recent apps, then restart it.

 

Restore from your nandroid backup. Then extract the files from the zip to a directory on the tablet's MicroSD. From there, copy one file at a time over to its proper location then reboot. Whichever file gives the inverted screen after copying it over is the source of your problem. Should the build.prop itself be the problem, pull the build.prop from the Mobiz ROM for the 8042 and put it on your tablet rather than the version in my zip file.

I don't have any other Coby tablets so I can't test these things. Which is why I'm asking you to do this for me.

ADDENDUM: I just reread your post. If this is occurring on only one of the tablets that tablet may be internally different from the other tablet. This is a known issue with Coby tablets. In fact there are three, possibly four, different versions of the 9742. However, I'm not aware of anything in the XML files that can cause this. There is ro.sf.hwrotation=180 in the build.prop. However when I took that out of the Mobiz build.prop when testing it, I ended up with an upside-down screen. It was quite a trick to press the right spot on the screen without a proper visual reference so the tablet could be shut down.

Since you have a nandroid backup, you can also try editing build.prop to remove ro.sf.hwrotation=180 and see if that fixes your issue. That's assuming the build.prop in the 8042 version of the Mobiz ROM is the same as the version in the tweaks zip.

 

These tweaks are clearly marked for stock ROMs and do Livesuite users no good since the features they include, except the battery indicator, are already on the Livesuite 9742 ROM. In your case, even if you did get them onto the tablet they won't solve your problem.

Other than continuing to play with Livesuite, there's nothing I can or will do for you. I don't support Livesuite users.

 

Use the search engine the site provides and look for 9742 fixes. There is a thread on the topic that may be of help.

 

Not really, unless of course you made a backup of the original firmware before you put the Livesuite ROM on it. Most likely, you didn't, in which case there's no way to get you back to the state you were in prior to messing around with Livesuite. Worse, trying to install ClockworkMod on top of a Livesuite ROM has bricked (rendered unusable) tablets, which is why the disclaimer for my root utility makes it clear that such an activity is not supported and done at your own risk.
