In a perfect world, you are always flashing from a bootable system that is either recognized by your PC, or you can use the reboot app to reboot to flash.

Since we are all human, and either don't follow instructions, or your ROM cook made a mistake, and you are stuck in a boot loop...the only way to get back into flash mode to fix the error is to manually put your tablet in flash mode. By manually...I mean using external buttons on the tablet.

I've explained how to do this on the M8 Pro, and I've given these same instructions to other Pipo tablet owners. It appears that Pipo uses a different combination with a bunch of their tablets. Here is a chart outlining the Pipo tablet and the combination of keys to get into flash mode.

DS820 803D: press the M key for a few seconds, at the same time press “reset”, release M key until the tool finds out your tablet.

M8 M9(android4.1.1) : press the ESC key for a few seconds, at the same time press “reset”, release ESC until the tool finds out your tablet.

M1 M2 U2 S1: press the “ volume –“ key for a few seconds, at the same time press “reset”, release” Volume – “ until the tool finds out your tablet.

M3 M5 U1 U3 S2 S3: press the “ volume +“ key for a few seconds, at the same time press “reset”, release” Volume + “ until the tool finds out your tablet.


M6(android4.2.2):press the “ volume +“ key for a few seconds, at the same time press “power”, release” Volume + “ until the tool finds out your tablet.


M7pro U8 M8pro M9 M9pro(android4.2.2):press the “ESC“&“power” key for a few seconds,no need of pressing reset key.
I haven't tried these, but it will get you close...you might have to sit and play with it in order to get it to work. It took me about an hour the other night to figure the M5 combination out on my own...I wish I had seen this the other day.
