Pipo M9 Max 4.2.2 RileyROM 1.5

You need to be able to unpack the firmware image. Look for wendal tools it allows you to do this in windows.

Once you have everything unpacked you need to mount system.img in Linux.

sudo mount -t ext4 -o loop system.img mntsystem

Then as root browse the app folder and cut them and paste to a folder outside mntsystem. (So it doesn't create a trash folder in your system)

When you are done...sudo umount mntsystem

Then you will have a debloated system.img

Be careful, though because the English versions don't have much bloat in them. Most of what is there is required for everything to work right.

Now the Chinese versions are a different story. There is plenty of bloat in them.

Randy,

Thanks for your tips. Already playing with image.
Regarding the playmarket error and APK installation error I managed to fix it.
By comparing the your image and the stock image I've found out that you removed app/MediaProvider.apk which is critical. (IMHO)
After I put it back and flashed my device everything went back to normal, playmarket works and no more APK install errors.

Oops. Sorry. Live and learn. I'll fix it Monday when I get back.

Reflashing

Hi,

I just reflashed the ROM and didn't use Titanium backup. Everything works fine, 12Gb user app, PlayStore etc

Hi Randy.

First of all, thanks for your work with this ROM. I've got a link to this forum via a Google alert I've setup for the Pipo M9 and immediately sign up here .

One noob question however: what is the advantage / disadvantage of setting the user space other than 2GB, which I assume is the default?

Thanks.

[rrileypm]

I'm quite happy with 2 gig user app space...I've never run into problems running out of room to install apps. However, some people like to install many apps and I get requests all the time to make this space larger.

Keep in mind that on older tablets, there was only 8 or 16 gig of NAND flash space available all together...and this increased app space takes away from the internal sd storage size. I prefer having more internal sd size vs more app space...others like it the other way around.

It really depends on what you use your tablet for...storing music/videos to watch...or playing many many games and stuff.

My fellow developer, 900Supersport started providing those 4 sizes in his ROM's for Cube tablets...so I started offering the same in my ROM's as a standard. I have to be careful, though...I have created those parameter files for tablets that didn't have enough NAND...and got errors. So I have to look at the specs a little closer.

No problem with this tablet...it has plenty of NAND memory.

On one tablet, recently I had a request for 12gb user app space. I'm not sure exactly why so big, but I was able to make a parameter file for it.

All righty M9 fans.....I just finished fixing and uploading both M9 ROM's to include the missing MediaProvider.apk that was causing problems with Google Play Store downloads.

Try this and see if it fixes the problem for you.

Just follow the same link in post #1...the file name is the same.

That's the only fix at this point.

Thanks for the explanation. I think I'll stick with the 2GB version, never had any issue installing apps so far, I think it's enough for my usage.

Reason for Bigger app space

You may be wondering why I requested a 12GB user app space. THis is the explanation.

Pipo M9 storage is setup as follows:

System - 2GB
Nand Flash - 12.5GB
External SD - (size of your external SD Card)

The problem here is you are stuck with the 12.5GB for your apps because the nand flash is the SD Card of the device. This leaves your External SD card useless regardless of size.

If you will try to edit vold.fstab to swap the system partition with the external sd, it isn't possible because the 2GB system space isn't mounted in vold.fstab. You only see nandflash and external sd there.


But with the 12GB parameter (thanks to Riley), the setup will be like this:

System - 12GB
Nand Flash - 2.5GB
External SD - (64GB for example)

Since nandflash can be swapped with external SD, we can have:

System - 12GB
Nand Flash - 64GB
External SD - 2.5GB

With this set up, your external SD won't be useless anymore and you can still take advantage of the 12GB space.

That problem, I'm afraid is in the firmware. Hopefully Pipo will fix that in an update.

Could you make a rooted ver of 4.1.1 of it. It has a fix bluetooth nd wifi but prob is some apps wont even play like nba or world war z it says unfortunately app has stopped. U got it fixed here at your 1.5. The stock rom is also at the pipo web.

Ok thanks randy. To let you know the bugs i found on the stock firmware 4.1.1, some games wont open and says unfortunately app has stopped.. good example is nba2k13.. and world war z, although i found 4.2.2 quite fast, maybe u could fix 4.1.1 speed on browsing. Again thnks randy in advance.
