Kinda noob here. Installed los 14.1 (unofficial) on my mi pad. It had omx issues, but I fixed them by removing two lines in build.prop (however now it only works on shield blobs). Then, after I booted up, i noticed that the 3dmark scores were low(1499- due to lower clock speed). I tried to fix this by flashing f1xy kernel, but the cpu now underclocked to 1.6 ghz. So, I modified init.foxy.rc of the kernel using codeblocks so that the cpu would boost up to 2.2 ghz and would aim for 85% usage. The score went up to 2050-ish and the cpu boosted up to 2.0 ghz. Heres where I decide to do something stupid : I decide to overclock it. I pirated tegra overclock just to see if the thermal guard was active, it showed that the thermal guard became active at 91 deg celsius. I was not aware that this app did not support my processor(tegra k1) so I assumed that the kernel was bad and flashed smoke instead, also modifying it to boost all the way upto 2.2 ghz. Then I booted and saw that thermal protection was still at 91 C, so I flashed magisk and tried to lower the temp to 80 C. It was buggy and I was unsure of whether if it worked. Then I realised that the app did not support tegra k1, so I clean flashed los 14.1 with f1xy kernel, this time with a preferred load of 95%. When I booted up and tried to install 3dmark, the cpu went up to an insane temperature(sharp hot to touch), so fearing consequences, I shut it down immediately.
My questions are:
Does the tegra k1 have emergency shutdown?
Which file specifies the junction temperature?

Zoom and WebX both not working in this ROM. Zoom gets stuck on opening the app and WebX does not connect after sign in. Any fix? Thanks

Did anyone get to fix the WebView issue? Whenever I start using the browser, I start facing a crash issue. it also happens with some of the android apps.
I got freeze on Zoom Cloud meeting app after log in on it. But, if I do not login, it work well. Did anyone have the same issue ? or know how to fix it ? Thanks
I am facing issue with Microsoft Teams not being able to log in. It works from browser (Chrome) but not from the app. Any one figure out whats up with the login issues with certain apps (Teams, Xoom etc.) Willing to experiment if someone has suggestions.

159Here is first attempt to build LineageOS 14.1 for XiaoMi MiPad
Current state is: mostly working
I finally found solution to fix old mipad stock graphic blobs to load on cm13 and Los 14.1. This build is proof of concept to show it is possible to have Nougat on old good MiPad.
What working:
- WiFi (better than 12.1, now using opensource wpa_supplicant)
- Sensors (autorotation works)
- LEDs
- audio including microphone
- hardware accelerated video playback
- camera
What not working:
audio (currently plays only some system sounds, all other failed because of wrong PCM format)camera
[*]lineage Music add doesnt play anything (3rd paty players seems to work fine)
[*]windevine drm not working (need updated liibs, to be done in next build)
[*]probably hardware acceleration playback (missed symbols for some omx libs)
[*]not enough space to install gapps into /system partition
[*]random crashes going to system ui restart loopwebview crashing with ERROR:gl_fence_egl.cc(63)] Failed to wait for EGLSync. error:EGL_BAD_MATCH (gapps and play market unusable)

Webview apk is one patched to work on broadcom GPU with same problem as ours: https://github.com/manumanfred/android_external_chromium-webview
2017-09-11 NEW!
Changelog:
- Lineage OS 14.1 sources updated
- Webview updated and rebuilt with only changes necessary for Mi Pad. Most of webview related issues now resolved. Faster and smoother scrolling in webview based apps, some apps now startings works, like Gogle Books. See webview patch applied below.
- device tree cleaned for proper work with proprietary blob files. Now they can be extracted from stock rom or device and makefiles can be properly generated in vendor.
- Using opensource version of libbt-vendor - maybe some changes in bluetooth perfomance.

Last Updated 2017-09-1145I'm still here. there is no new builds because there is no major progress in device tree development. I made FM radio tuning works, but there is no still sound from radio.
Also I have found that blobs from https://github.com/Toradex-Apalis-TK1-AndroidTV/proprietary_vendor_toradex_apalis-tk1 are compatible with MiPad and it provides NVIDIA 343 driver. This driver resolves random EGL crash (no need to patch lineage source libEGL), but it still doesnt work with webview.
But there is another thing. Nexus 9 (flounder/volantis) 32 bit blobs are compatible with MiPad as well, and it provides same NVIDIA 343 driver. Using all jetson blobs and replacing /system/vendor/lib/egl files with one from Nexus 9 vendor image fixes webview issue.
All these new blobs are great but it breaks camera on lineage 13, and it have to be resolved.37Webview issue maybe solved with patched one from here https://forum.xda-developers.com/showpost.php?p=68748670&postcount=27
https://github.com/manumanfred/andr...ew/tree/nougat-mr1.2-release-bcm/prebuilt/arm
It have to be installed as system app like described here https://www.chromium.org/developers/how-tos/build-instructions-android-webview
I will include it in future builds.27Sorry for long silence here, but finally did something new. Now Lineage 14.1 with working cam (old blobs) has major improvement in term of working with webview apps like Google books, Gmail and many more.

check first post for download links.27If it possible to make los14.1 run stable and sound working it is better to go with los14.1. At least it has upstream support, and some things here works better. I cant make opensource wpa_supplicant working on 12.1, but here it works. Microphone in cm12.1 is also hard to fix, because there is only LD_PRELOAD for lib and microphone require MonoPipe class from 4.4 to work, but it will break other things. On cm13 or los14.1 it is possible to use LD_SHIM_LIBS to fix only broken libs and not break working.
For now I'm trying what cause los14.1 unstable, sometimes it may work for hours, but when it crashed to black screen and buttons backlight it starts endless bootloop.
