porting lenovo smart tab m10 plus x606

@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 ?

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.

marek_python

@kugiigi
Unfortunately I'm sure as it is the second ROM I tried and it was 10. I reckon it was the oldest release in that downloads folder which is little bit odd since it was supposed to be downloads folder with Android 9 releases.

I'm trying to find out if there's any chance of getting TWRP working on it but how if it won't even boot into fastboot.

kugiigi

@marek_python I see. Actually I kind of remember that there was indeed weird with the dates there. Does SP flash tool still detect your tablet for flashing?
Also, have you tried Lenovo's rescue tool?

On a side note, Dalton was indeed correct, flashing this tablet can be a PITA I thought when I successfully did it, other people can just following my steps and notes.

Luksus

What was important for my device, that I also choose the right "Download-Agent" (MTK_AllInOne_blalba.bin) from the image folder, which I wanted to flash.

I had the impression that it starts to flash more reliable without error, if I press (only) the volume down button, while plugging the usb cable.

Then I have had an issue, which is described here together with a solution:
https://www.programmersought.com/article/74183233522/

But as you already did a successful flash, I don't think that you need this.

I am still not sure if you tried to boot your devices, without any plug in it... For me it was a solution sometimes.

It is also worth to try different long-press combinations with volume up/down or all together...

~~And did you try to enter fastboot mode?~~ ah, you did

@kugiigi
No the flash tool isn't detecting the tablet. Good thinking with the Lenovo Rescue Tool. It has option to restore completely "dead" device. Sadly the restoration progress is stuck on "connect device and do flashing". Following:

Power off device (done. It's already dead ) and disconnect from PC
Press volume up and connect to PC with USB.
Click OK to continue
Release volume key after restoration begins.

It looks like even their own tool can't detect it.

Will keep trying. All UT devices I've had were acting up at first and then they folded and UT was on it.

Here the same.....starting lenovo rescue tool 40%, waiting 20 minutes nothing happened now it Ended With failure

marek_python

@fp2andfp3-user
These tools should detect device within few seconds. It shouldn't take minutes.

I'm just wondering what we've done with it that even this tool can't seem to help.

I'd like to suggest to flag (or delete) that ROM from list of downloads. At least 3 devices are dead because of it.
The last thing the UT community needs is more dead tablets.

kugiigi

Do you both have the same issue? Just blank screen, not even the Lenovo boot up screen?

marek_python

@kugiigi
I've got completely dead tablet. Won't power on.

Things I've tried and done:

pressing and holding different combos of buttons to invoke
fastboot
checked if tablet can be detected by SP Flash Tool
downloaded and installed Lenovo Rescue Tool and checked
adb and USB drivers. (tool won't detect tablet on pressed volume up and plug in)
posted and researched on XDA site.

kugiigi

Oh wow....that sounds bad....
not even a charging screen or something? No fastboot or recovery?
I'm trying to get back all my conversations about my flashing journey. So far, it seems that the worst was my tablet is bootlooping in the Lenovo splashscreen and no charging screen. But I was able to reflash the latest stock ROM with the Lenovo rescue tool. After that I tried again and followed the steps I mentioned earlier and it went successful. Hopefully, you can still recover yours and flash UT. I think someone said that this tablet isn't easy to hard brick so good luck

kugiigi

I was told that you can try pressing volume up when plugging the device to your PC or volume down.
