RESOLVED: M6Pro bricked after installing RR1.7

[rrileypm]

The first time I did it, I gave up and went to bed...got back to it 2 days later and it worked.

Sometimes, you just need to walk away from it for a while.

Hi,

i got the right pins. Its pin 8+9 at the nand witch is located next to the battery.

I got "MaskMode" but just for 5 sec. than the device disappear and is says "No found...."

Is there a trick to stay turned on?

Greetings!

[Schmo]

i got it!!!!

Thank you verry verry verry mutch for your help.

I pluged in the wall charger and then it worked! Mayby the battery was empty

Short how to for other people:
1. Open the tab
2. Open the flash tool.
3. Connect the tab to the pc
4. Connect the tab to the wall charger
5. Shorting pin 8+9 at the NAND witch is next to the battery (in case of Sandisk NAND) see this: http://abload.de/img/nand0xbuy.jpg
6. Power up the tab
7. It should appear in MaskMode
8. Erase IDB
9. Make sure that you have selected the loader and the rest you want to flash
10. Click Flash Rom

That's it.

Again, thank you verry mutch!

unbrick m6pro unother method

I bricked mine and by accident found a way to unbrick it. It did not react in any way. When attached to pc and holding the power button for a few seconds i heard a connection sound. Checking with rochchip flashing tool there was a blue sqare when holding power pressed. So I tried to reflash while holding power button pressed. That worked for me a few times, but NOT when I released power button to soon. You can release powerbutton after the first part of flashing completed. Then the bootloader is flashed. So there is no need to open the tablet.

Are you sure?
Did you brick the tablet flashing kitkat without the loader or in which circumstances?

[rrileypm]

Usually the brick happens when you try flashing back to 4.2.2 without flashing the boot loader.

Yes I flashed to Kitkat with kastyrom. No problem after that. I tried to flash back to Jellybean stupidly without reading about bootloader. I got in red failed. After that no response anymore. The tablet was absolutely dead. No reaction on whatever reset or buttoncombination. Window7 could it not find anymore. Only when pressing and holding powerbutton I heard the windowssound of connection and I saw the tablet in windows, but it disappeared when the powerbutton was released. So there was a little sign of live left.

With RKBatchtool 1.7 I could repair in an new manner I found without opening the tablet Pipo M6pro:

1 I connect tablet over usb.
2 I load the right rom-img file in RKBatchtool.
3 Hold the power button.
4 While holding press restore button in Batchtool.
5 Keep power pressed untill first part of flashing is done (button is green by now)
6 at first I released the power to soon and the contact over usb stopped, so did flashing and I had to start over.
7 Flashing completed and pipo rebooted again to normal. Succes.

I could repeat it. Perhaps the same procedure works for other tablets. I am curious.

I have no problems but is good to know!!!

even if my tablet is still open waiting for the new antennas

Thank Schmo!! I could not unlock my tablet but with your procedure went ok.My nand is a Micron but at this point I think it does not matter the brand, I think it is the correct procedure for all M6PRO 32GB

[Schmo]

Did you short 7+8 or 8+9?

[at00]

Did you short 7+8 or 8+9?

I shorted the 8-9 pin as you indicated, but I do not know their function because I could not find the data sheet or better micron does not allow the download of the file

[Schmo]

Ah ok. Good to know.

Thanks for making this thread Sticky!

Tablet umbricked with keeshg method

Hi

I bricked mytablet (Pipi M6 pro 3g model) trying to flash kasty 4.2.2 jelly bean ROM in the tablet previously flashed with kasty 4.4.2 KitKat ROM. The result of this is well known: Tablet bricked.
Before opening the tablet, i decided to try keeshg method to unbrick and flash kasty 4.2.2 jelly bean ROM.
I did no release power button until the complete process finished, but the process was sucessful. My tablet is alive again.

Thank you so much keeshg

Hey,

Another careless person here who bricked their tablet. I bricked mine by flashing back to JB without the loader ticked. I was worried I had done something worse as I was getting no response at all when I connected it in Windows even with the power button held. I realised that when I pressed the volume up button on the screen with the android on it's back with a red triangle I got a number of options. With the device connected to my pc and the flash tool open I chose wipe cache and then wipe data/factory reset. I then chose reset device now and the flash tool detected it. Not sure why that helped but I am up and running now so it may help someone else.

Cheers
