M9 Max 1 NAND strange brick

[brunom80]

Guys, this is awkward, but how can it retreive my tab from MaskMode??
I mean i won't let me load any FW on nand in this state, while on "green" mode i can go allmost all the way to end of the flash.
Everytime i reset it goes in to mask, if I unplug the power... same, tryed shorting ground pin to reboot... same.
Unsoldered the battery now to see how it goes
Talked to Riley already, but new facts came up and wanted to talk to comunity.
Maybe the NAND is dead, but in "Loader"(green) mode i can upload, do low level format etc all without retreiving errors. But never made a successful unbrick

Strange..
Some help please

If you have a defective nand flash maybe you can give this a try.

I'll be sure to try it.
But everytime i restart the tab, it goes directly to mask mode. If the micro SD is inserted, you think it will booth from there?
Or how do I get out of mask mode????

Thank you

I think that will work no matter the nand flash state. I can't guide you how to get out of mask mode.

I´ll try it as soon as i can.
Thank you so much.

Didn´t worked.
It boots in to mask mode, i can´t access anything else.

Any other suggestion?

I didn't expect this. Push reset button and retry. How do you know that your tablet boots in mask mode. You have to connect tablet to PC to see that is in mask mode.

Are you sure that you understand what you have to do with microSD.

[brunom80]

Yeah i confirmed it by connecting to PC.
I think there's not too much hope.
I reset, back to mask....

Ιf you made bootable microsd correctly then i can't think something else for you.
You mean that you place bootable microsd in TF slot then you push power button and then nothing happens , just a black screen? Then you connect tablet to PC and you see that it is in mask mode?

Hi Kandilak,
Sorry for the long absense, i have sent the system board back to pipo and it is flashable now again.
