porting lenovo smart tab m10 plus x606

@fp2andfp3-user I think I used that tool too. I already forgot the steps I did but I indeed had many mishaps. I'll try to go back at them and let you know

I found these steps I mentioned in the telegram group after I successfully flashed mine so I guess these are good pointers to not encounter the same issues I had.

Download the oldest image for your device and use that to downgrade your firmware
Make sure the firmware is correct for your model. Mine is X606F as shown in on the box.
When using SP Flash Tool, do not uncheck preloader even though the guide would tell you to do it. Make sure to use "download" or "firmware upgrade" mode, never "format all and download"
Once you downgraded, try to boot and complete the device setup
Download the standalone fastboot instead of the one provided by your distro (i.e. Ubuntu)
Make your device has enough battery and your USB cable connection is stable

@kugiigi so my tablet is Broken i did flash it With SP flash tool and it said download complete. Now nothing happened....only red light, if i Connect it to the laptop.....what is the Problem? What can i do? It said cannot recognized Hardware.....

@fp2andfp3-user did you try to unplug the cable and just push the power button?

FP2andFP3-User

@luksus yes I Tried.....nothing happened.... 75 seconds.....nothing only red light led

Luksus

@FP2andFP3-User
Is the red light on, even if no cable is plugged?
When flashing, did you leave the preloader checked, as kugiigi suggested?
Which device do you got exactly: X606X, X606F, X606XA, X606FA ?
Which image did you flash?
Can you enter fastboot mode: long press power + volume down together?

I was in similar situations multiple times, so I think there should be a way out.

Can you try to reflash it with SPFlashtool, maybe with the next newer image version?
Normally the device is off, you start the download-process in flash-tool and then you connect it the usb-cable, but sometimes I needed to push the power button, if nothing happened after connecting usb (I did experiment with preloaders from different versions, what did not went very well and I ended up in the same situation like you).

@kugiigi @Luksus

do you know the correct mtk driver for Windows 10 i flashed it there .....maybe i can rescue With that and the rescue tool from lenovo? Or maybe another flash tool?

Thanks

kugiigi

@fp2andfp3-user The official tool from lenovo helped me recover mine before. Try that.

FP2andFP3-User

@kugiigi i have Tried yesterday but which driver? Before it recognized and after it told me cannot connect hardware

kugiigi

@fp2andfp3-user Sorry I can't remember anymore the details. From what I remember, the tool just successfully reflashed android on my tablet without much fuss.

Hi all,
I got this tablet just today to flash it with UT.
I've followed instructions here https://gitlab.com/ubports/community-ports/android9/lenovo-tab-m10-fhd-plus/lenovo-x606#install

One of the steps is to downgrade the tablet to Android 9.
I tried ROMs from here https://mirrors.lolinet.com/firmware/lenovo/Tab_M10_FHD_Plus_2nd_Gen/ one by one to find out which one is Android 9. After flashing the third ROM tablet won't
power on anymore. LED indicating charging is on but pressing
the power button does nothing and holding volume down + power button does nothing either.
SP Flash tool gave no errors during the flash yet the tablet won't
power on.
My model is X606F MediaTek.

Any suggestions ?

@marek_python @Luksus
The same for me i will check More Details in the evening

I don't know if it helps but I noticed this error output when trying to flash the tablet with another ROM. Right before it fails it outputs:

I got this output by pressing the power button while the flash tool is attempting to connect.

@marek_python mh, I think that is an expected error, if the device is not turned off, when trying to start the flash procedure...

So what happens, if you start the flashing process, then connect the usb at the turned off device without pushing any button?

kugiigi

I believe this is the Android version I flashed on mine - TB-X606F_S100015_191127_BMP since I still have a copy of it.

Am I correct, that you both haven't even successfully flashed/downgraded Android and booted?

marek_python

@luksus
OK so it looks like me pressing the power button had no effect on the error. It outputted the same error without me touching any buttons.

Failed to connect DA is at least some clue.

marek_python

@kugiigi
Yeah that's right. I'm trying now just to get Android 9 working on the tablet.

marek_python

@kugiigi
I had TB-X606F_S100015_191127_BMP working on the tablet. But it was Android 10, not 9. Then I went on the next ROM which is the ROM ending 923 and the tablet won't power on.

kugiigi

@marek_python Are you sure? Hmm...as you can see in the downloads site, it's the oldest file there so I would assume it is indeed the very first version.
