How to downgrade Yoga YT-X705F to Android 9

2021-01-15, 4:28 AM

My Yoga YT-X705F got automatically upgraded to Android 10. Android 10 is a hot mess on the Yoga YT-X705F, after the upgrade the tablet is sluggish, buggy and consumes battery life like crazy. Is there a way to downgrade to Android 9?

Just updated this am as well.  Was glad to see the update but now not too happy.

 

I cannot connect to any wifi network, open or closed.

I get a message,  "failed to save network" then  "failed to connect to network" .

 

Device will be a brick if I can't connect to the network.

I too made the mistake of upgrading to Android 10. However, I have other issues. 

I keep getting a message that my SD card is missing and to reinsert it. I have done this several times, and formatted it in the tablet, but this issue persists.

Outlook, skype, and files by google keep reverting to older versions on restart. I am only using Outlook, but this causes a repeating message that Outlook has crashed.

When I restart the tablet, the tablet does not boot back up. I have to hold down the power button for a long time to get it to boot.

 

I am very disappointed, I really wanted gestures navigation, but now I'm left with a useless tablet. 

I use this for school, and I need Outlook to function for my college email.

 

I need to revert back to Android 9 immediately. I start classes again in 3 days...

OK, I think I solved my problems. I don't know if this will help others, but here is what I did.

 

While trying to go through the steps to submit a service ticket I performed a "wipe data/factory reset" and "wipe cache partition" as explained here

Lenovo TAB Trouble Shooting Guide V2.0

 

When I went through the setup process, I did not import any of my settings. Instead I treated this as a completely new setup.

 

Now my outlook stays current and functions normally.

 

One of my other problems was it not recognizing the SD card after reboot returned, but I just formatted and renamed the card and that seems to be working now.

 

Restart functions normally now.

 

This does not revert to Android 9, but fixed the issues I had with 10.

 

I will follow up if any issues return.

 

I hope this helps others.

Thank you for the suggestion ... this is exactly I don't want to do, going back to a manufacturer reset. Pretty disappointed with the quality control from Lenovo. Given the number of problems reported in this forum, this version should never be released.

Hello all

 

I would also like to be able to downgrade (or in actual case upgrade to a stable OS) mine and my mum's Lenovo YT-X705F back to Android 9. Since the Android 10 update our tablets are close to useless!

 

We have the Outlook app instability and accounts disappearing issues along with not being able to turn it on, Tablet being slow to boot up and also the Micro SD card functionality being unusable.

 

Both of these tablets are only weeks old. 

 

Since this latest OS update has made two brand new tablets close to paperweights I am seriously thinking of trying to downgrade mine as I have seen a possible way on other sites, I just hope it doesn't brick it.

 

Please OS / Manufacturers make it so that we are not forced to install "New" OS's and make it so that owners of our own equipment can revert back to previous versions when things clearly do not work correctly.

hi all...

 

you gotta tick the lmsa into thinking that the folder of the old rom contains the new updated rom.

 

for eg mine is,

 

C:\ProgramData\LMSA\Download\RomFiles\YT_X705L_S001119_201210_ROW

 

&

 

C:\ProgramData\LMSA\Download\RomFiles\YT_X705L_S001032_200828_ROW

 

 

 

so just rename the new folder to eg. C:\ProgramData\LMSA\Download\RomFiles\1

then rename the old folder to the new one...

 

does the trick....
