Pipo P4 RileyROM 1.5 (Android 4.4.4)

The buttons are labeled different, but the process is the same. And you do have them correct.

With the 3288 SDK, Rockchip introduced this new naming scheme for the parameter files. You don't have to rename them at all...just select which one you want to flash.

The next ROM will have an updated First Time User's Guide.

Followed the steps like you said. But when hitting the lowerformat button, I get lower format failed. Is there anything that I can do so I can get an format? I use W7 64B.

So far I have not successfully erased idb on either of my 3288 devices. But I can still flash the ROM.

So the low format doesn't work, you just press switch and then press run?

That's something I didn't think of. I try it when the next P4 comes in. Thanks.

It looks like I'm to hung up on thinking the M series way.

[rrileypm]

That's correct. Just click run.

Riley, do you have more feedback from users on the 1.5.1 ROM regarding the battery drain. At the OMA 1.3 rom i still have 4% per hour with wifi off+screen off.

I now got 1.5.1, i will check battery drain but you can still see that 'mobile network signal' is eating battery but there's no built-in 3G offcourse...

Edit: i'm at 3.6% loss per hour in standby (wifi off), and the android app is telling me the screen is "60%" of de battery life. But how is that possible? It should be 'mobile standby' or something with the biggest percentage right?

I have charged for the last time 2 days ago, used the tablet for roughly 1 hour and I am at 66% right now. Still running 1.5.1 so I guess this is pretty decent.

That's fine, can you upload a pic from the battery stats?
Mine is like this, i'm curious if you have the same.

Starcopy, did you notice any difference with that libril file? If so, I can incorporate it into the ROM for everyone else.

I didn't have enough time to test it properly, because the P4 wasn't mine. But it did look promising. I will ask one of the users overhere if the are willing to test it.

Here is a file you can flash with CWM or TWRP....but I don't think we have one for this tablet.

So, extract the libril-rk29-dataonly.so and replace the same file in system/lib. Give it rwx permissions.

I just installed it. Weirdest thing, after reboot Google now launcher became available. Also the original libril-rk29-dataonly.so was set to rw- r-- r--. Can I confirm proper functioning other than waiting for battery to improve?

Here's screenshot of current battery setting before this change. In these days I used to read a few PDFs and I streamed videos via XBMC for 1 hour next to some browsing.

I also changed the file now, only thing i had was that i couldn't charge my battery to 100% (it was stuck on 91).

i found a cool version of xbmc that has solved all my problems.... fingers crossed..... live tv seems fine and lack of crashes on the 3288.
