Re: Tab4 8 Problems with 8.1 Oreo update

You have to enter the password, did you do that?

Re: Tab4 8 Problems with 8.1 Oreo update

Yes that is the correct password. .. I just took all the screenshots, I'll be writing up instructions now. 

 

You can make a folder on your desktop. Name it lenovo. One word. Then unzip the firmware folder to the lenovo folder. Or the desktop. 

 

Download the miflash tool at the link I shared. 2016 version. Install it. It's simple to install. It's a tool specific to flash qualcomm devices, it does load drivers. 

 

Then wait for my tutorial.

Re: Tab4 8 Problems with 8.1 Oreo update

power the tablet off. connect the data cable to the tablet.  Dont connect to the PC.

 

open MiFlash. 

 

Choose the flash all option at the bottom of the window - this wipes the internal storage, data, cache, dalvik cache. this option will give the cleanest flash.  

 

Click on Browse and scroll to the folder where the unzipped firmware package is and choose Images. then Click OK.

now you will see the firmware loaded into the top of miflash.

 

 with the tablet off, press just the volume up button and connect the data cord to the pc USB port.  The screen will remain black but a red light will start blinking.

In MiFlash presh the refresh button.  This will connect the tablet to miflash and you should now see the tablet shown as COM8 or COM9. ( other numbers may be possible.  I've only seen 8 & 9.)

Now you can click on Flash and you'll see the tool flashing.  It only takes a few minutes.

When its completed, disconnect the tablet from the PC.  Hold the power button until it vibrates. (30 seconds or so )

Re: Tab4 8 Problems with 8.1 Oreo update

Sorry it took so long.  It's the first time I uploaded so many photos here.  A little bit of a learning curve for me, lol.  But I got it done.  Good luck.

Re: Tab4 8 Problems with 8.1 Oreo update

So far so good, I owe you a big one. It booted up and automatically started downloading update S000061 which I think is the last one before Oreo 8.1.

Personally I would like to be able to go back to S000054 which I believe is one prior to S000061 because I’ve had a few minor issues with S000061 but it’s better than Oreo. 

 

Any idea how I could go back to S000054?

 

Thanks again for all your help. It’s installing S000061 right now so hopefully it goes smoothly. 

 

Here’s video of the annoying issue I’m having with S000061. Not sure why it wants to rotate when I tap the square.

Re: Tab4 8 Problems with 8.1 Oreo update

I got it finished.  Thanks to you my tablet is back to its former glory prior to Oreo 8.1.  That update was a mess.

Re: Tab4 8 Problems with 8.1 Oreo update

Awesome. Glad it went smoothly. If I'm understanding correctly, everytime you click the back button the tablet rotates?  Go to settings / display and see if auto rotation is unchecked.  If it's checked, uncheck it, restart the tablet and check it. 

See if that repairs it. If it's unchecked, check it. 

 

 

The Oreo update was pulled, "fixed " , and re released.... I used miflash and went back to nougat, as you have done. Then allowed the Oreo update. All the issues I had with the original release are no longer present. Maybe you could try it again also. If problems persist, you can go back again, now you know how to do it. 😊

 

Also, to answer your question about updating to a specific update... The specific updates are on the Russian site. They have ota ( over the air ) in front of them. I have yet to try flashing one. I don't know how, to be honest. Possibly loading it into miflash, same as the full firmware, then flashing it. But, as I stated, I haven't tried it. You would need to be on the original firmware you flashed with miflash without any updates first. Then flashing the ota, if you're going to try. ALSO, if you try... Don't check the flash all box at the bottom. You should be able to flash the ota update without wiping everything and loosing your data, choose the option farthest to the right.
