Thank you!

bricked?

Hi Riley,

I have a Pipo M9 Pro tablet.
Since I got it, I used Finless 1.5 ROM, but had some weird reboots randomly, so decided to use your rom. Sure I installed Kitkat without any problem (RR2.7.2). But my favorite game (Clash of Clans) simply did not want to work on the tablet. After some googling, I decided to switch back to JB.

So I found this topic and followed your instructions step by step.
Everything went fine the counter counted to the left number successfully on testing, and the only remaining thing was the reboot, then my tablet's screend simply turned black... Waited a few minutes, but nothing happened. Now it seems that the tablet does not react to anything, so I'm stucked. Please tell me that I didn't ruin my tablet and somehow I can "unbrick" it.

My config was the following:
Pipo M9 Pro 3G
Tried to flash from RR2.7.2 to RR1.8 (as you wrote it's the latest stable JB)
Windows 7 64bit (drivers were there since I installed Finless first, so that's ok)

Thanks for your answer in advance!

OK, news: fortunately (after some really angry hours) I could reflash the 4.4.2 (RR2.7.2)
But my game won't work on this rom That's because of the softkeys somehow it freezes. Which is interesting because on my Nexus4 it's working without problems.

UPDATE:

Rootcause: immersive mode of Kitkat

After some more googling, found this article (the symptoms are the same, video also included on the link):

https://code.google.com/p/android/issues/detail?id=62366

The interesting thing is that I also have 4.4.2 on my Nexus 4 and it works with the game's built-in immersive mode now.

Going Back to Pipo Firmware

I want to go back to this Pipo Firmware, M7pro_#70_update_OTA-20131130-v1.0.6.img, What would be the procedure to do this?

[rrileypm]

This will involve a few steps to be safe.

First, open the KK ROM flash tool and erase idb from it. Then flash the JB RILEYROM with the flash tool included with it...making sure to check the loader.bin file.

Then you can flash the stock JB firmware with the batchtool.

[rrileypm]

That's assuming that factory firmware is JB...I don't remember off the top of my head.

Are you able to flash back to the KK ROM?

riley flashed back to KK rom and that works, but the KK rom is not stable, the tablet everytime needs thinking and is slow everytime using chrome or firefox, therefor i want to go back to jellybean.

What is the best rom for the m6pro 32 gb 3G?

Thanks in advance!

Riley, did manage to get back to KK 1.8 and did a full erase idb (twice) with the KK ROM flash tool. Then flashed the JB RILEYROM with the flash tool included with it...i ensured to check the loader.bin file.

Now it can't boot further, so i hav the same problem...strange!!

Do i need to flash to a original stock rom?
