What is "tile for activating\deactivating battery charging"?
- this is system icon(like performance profiles) which permits\prohibits the supply of current to the battery at the time when the charger is connected.

Why do we need that tile?
- if you play, watch a movie or perform another costly action, then activating this mode will save the battery from unnecessary wear because energy will go directly from the charger. But you need a fairly powerful charger, if the power of the charger is not enough, then partially the consumption will be compensated by the battery.

What happens if you do not install TosForPSCI-0.1?
- at best, only one CPU core will be active. At worst, the recovery will not be started (if it has not been updated too) and the system too.

How to roll back on the firmware version, which came out before November?
- download TosForPSCI-0.2 and recovery. You'll be able to flash older ROMs after installing them

Why do I need to lower the PSCI version from 0.2 to 0.1?
- Using version 0.1 fixes a problem with shutting down a device.

does this have any bugs?

 

[uan]

What is this? Felt like new tablet.

 

[surfdday]

I flashed the latest ROM 10.10.2018 yesterday. The Wi-Fi is unusable - after the tablet goes into sleep for some time, when you wake it up, the Wi-Fi connection is gone (meaning it doesn't see any SSID at all). Turn off/on the Wi-Fi does not help. Only way is to reboot the tablet. Any suggestions?

 

[ayushagarwal9753]

staying on 14.1 due to only video hardware acceleration

 

[StarkAhmed]

Is it possible to flash LOS 15.1 without the shield blobs?

Is it possible to fix the camera by changing the permission of the build .prop file?

 

[Vishal P]

Great Build!! Keep it up!

 

[Vishal P]

There is one issue in display. The screen flickers some times while using the device.

Lol. No, it's not

 

[StarkAhmed]

Lol. No, it's not

By the way what are shield blobs and what happens to my mi pad when I flash LOS without the blob?

 

[XWERT]

I cant install it. Error 7 in flashing. Any idea how can i fix it?

 

[Vishal P]

Guys, install shield blobs properly before installing this. Read the main post carefully.

Hi, I also experienced the same problem. Turning airplane mode on then off solved the problem, wireless networks showed up and mipad connected automatically.

 

[Vishal P]

@Artemka2008 I am upgrading from October build to November. Should i remain in shield blobs or go back to mocha blobs? I can see from your instructions that for ROMs from November, flashing shield blobs is not necessary.

 

[Palm Trees]

Can't get the lastest rom to boot. Reverted back to Tos 0.2 and used the recovery before November, still not booting, stuck on MI logo.
Never experienced any problems before. Any suggestions are welcome

 

[Identity77]

Same with me. Stock with mi logo. But other roms work.
