casting issues

I've got casting issues.

When I hit the cast button and check "wireless displays", it'll find my Samsung Smart TV but when I select connect, it takes some time and says disconnected ! why ??

I installed "Allcast" app from the Playstore and it worked fine, but I want all my screen to be mirrored, not just the things I do through that app.
[G Pad 8.3 Android Development] tmihai20:
I got tired of the lag on the V30A (even with fishears' kernel it would lag a lot, because of the memory being constantly filled up) and of the SD card unmounts and I installed this ROM. I had to flash the V20D kdz twice because any of the SuperSU (latest stable or Beta) semi-bricked my tablet (it would not boot at all, I just saw the secure booting error). After searching through the thread I found out that SuperSU 2.52 is the version to flash.

I have found one major issue: just as on untouched LG stock ROM, the tablet would not see any WiFi networks on channels above 11. I had to modify 2 files to get it working. The first one is /system/etc/wifi/WCNSS_qcom_cfg.ini, line 258. I put UK as the country (it was TW and the line was commented):

gCrdaDefaultCountryCode=UK

I also modified /system/build.prop. Line 35 had no value at the end, I put 14.

ro.wifi.channels=14

If these 2 files could be modified in the source code, that would be great. I am also attaching them here. I found the info in the V30A thread.

Also [MENTION=4297659]adrianom[/MENTION] is there a MOB30D build coming up?
[G Pad 8.3 Android Development] killerskincanoe:
I can confirm this bug about youtube. Very irritating. On 11/18/15 build. Just came around to check for update. Holding off until this is fixed. Everything else has been perfect. Thx for all the hard work OP! Thx for mentioning the res drop fix. I'd been just watching youtube in the browser as a fix.
[G Pad 8.3 Android Development] tmihai20:
I think I had this issue on the 5.0.2 Koreean lollipop, I just did not give it too much importance. It may be an issue with Youtube and our tablet.
[G Pad 8.3 Android Development] Disrupthor:
Snapdragon 600 only supports 60fps on 720p by hardware, in 1080p60fps the decoding is done solely by the cpu and it can't handle it smoothly.
[G Pad 8.3 Android Development] dragonn3r:
Performance and stability on this rom is very good. No lags etc. But 3D games (especially GTA:LCS) is running slow, a lot of lag. I get back to stock 5.0.2 and 3D games running nice.
[G Pad 8.3 Android Development] tmihai20:
I have done a test. I uninstalled the Youtube update and reverted to the built-in app. Guess what? Youtube was now playing 1080p at 60 FPS perfectly. I read there are a lot of users having issues with Youtube on a lot of devices. The hardware on our tablet can handle it very well, it is the Youtube app that is far from being finished.
[G Pad 8.3 Android Development] indian84:
I agree.

It can also be SD600 & Adreno 320 are working overtime to push that 1080p 60fps YouTube to our screens. Hence they get tired and stop playing videos. :P
[G Pad 8.3 Android Development] angelcalibur:
hi!

just want to know if i'am alone to have this problem, but when i lunch a video (avi, mkv or mp4 for exemple) i've got some lag with vlc.

what do you use to read video file?
[G Pad 8.3 Android Development] indian84:
Nothing seen on MX player. I haven't used VLC.
[G Pad 8.3 Android Development] angelcalibur:
Hum, i will try your app! thx!;)
[G Pad 8.3 Android Development] indian84:
Glad to help.
[G Pad 8.3 Android Development] Doc Moody:
Sorry for the late reply -

I think that's normal aosp. but you can add reboot into bootloader etc by using gravity box module for xposed. At least that's how I did it and works fine. I sometimes get the prompt of the sd card being corrupted, but one reboot and it works just fine. It seems the pad can utilize 128 gig cards because thats what im using - a class 10 sd card by sandisk. Otherwise the rom runs great.
[G Pad 8.3 Android Development] Gh0st.be:
Hello everyone !

I have some questions to ask, because I'm a very noob at this kind of things :p

I own the LG 8.3 v500 tab, with Android 5.0.2 (it's the Korean official firmware).

But I'd like to upgrade to Android 6 with this firmware.

- If I do that, can I do it over the Koren firmware directly ?

- What about all of my apps ? Will they stay like if it was an official upgrade firmware ?

Thanks for your help :)
[G Pad 8.3 Android Development] indian84:
If you want 6.0, you have to flash a custom ROM. LG isn't gonna update V500 to Marshmallow.

And yes, you have to do a complete wipe, meaning all your app will be gone. You have to download all again.
[G Pad 8.3 Android Development] Gh0st.be:
Thanks for this fast answer !

I will think about it, cause I have lots of apps and games. Reinstall everything sounds very annoying :(

Is it really worth it ? Especially for the battery life.

Thank you :good:
[G Pad 8.3 Android Development] Deltadroid:
Custom ROMs are mostly developed so that devices receive security updates in a timely fashion (something most companies have chosen to ignore so they can sell more devices). The latest stock Rom for the v500 is full of security problems.
[G Pad 8.3 Android Development] Wolf Tatoo:
Is Vulkan api supported on this rom?
[G Pad 8.3 Android Development] indian84:
Seriously dude?

Google just added it to N Dev Preview 2. And TBH, I heard about it only after Samsung added it to S7 lineup.

If/ When we get Android N for our device, hopefully we will have Vulkan API.
[G Pad 8.3 Android Development] Deltadroid:
I'm afraid that the vulkan api in android N will be the end of our adreno 320 chips.
[G Pad 8.3 Android Development] indian84:
That's not a good news..
[G Pad 8.3 Android Development] Wolf Tatoo:
Adreno 3xx GPUs r not supported,but if some dev ports the Vulkan binaries to any other unsupported legacy gpu,then we maybe able to the same for this poor forgotten one too!

Hi,I installed the latest rom. Good job. I only have a problem with the installation of Viber which always calls for a new version of the app, and even Skype does not want to open .

any suggestions?

[G Pad 8.3 Android Development] dirlan2001:
Viber, I don't know...but for Skype, you'll have to look up an older version at the ApkMirror

how to do the rooting without blocking the boot?

I ask your help because installing Beta On Super 2.71, the system has crashed with this warning:

"Secure booting Error! Cause: boot certification verify".

I solve to reinstall the custom rom.

But now before rooting the tablet I would like to have some help from you to not block all again.

Thank's
[G Pad 8.3 Android Development] uzi2:
Flash supersu 2.46 or 2.52 - it is then ok to update via google.
[G Pad 8.3 Android Development] nstirton:
Quick update - having used the latest update for around a month, still frequently getting the SD card unmount error. Have also tried swapping memory cards and re formatting in the tablet to see it that helps, but no such luck.

I love this ROM but can't afford to keep having this happen. Thanks for your support dev!

Hi,

My GPad runs in an Bootloop after Installing the ROM and rebooting the Device (stuck at the android logo on bootup.. animation is still working so the device isnt frozen).

Till this point everything worked fine (Root, installing the ROM over TWRP).

Ive installed the ROM now for the Third time (2x without wiping the cache and 1x with wiping it). I have no idea what iam doing wrong...

its the first time for me flashing an Android Device
[G Pad 8.3 Android Development] Fistandtilus:
Try twrp version 2.8.7.1, worked for me, the 3.0 versions caused bootloop,

beast of a rom, fixed even my touchscreen issues
[G Pad 8.3 Android Development] dirlan2001:
If the bootanimation still runs, your device is still OK... First start might take very long, some patience pls :)

Just like installing a new GApps package, might take 10 minutes to get up and running.

Cheers

---------- Post added at 08:43 AM ---------- Previous post was at 08:41 AM ----------

First time I hear that.... running 3.0.1 now, no issues

Cheers
[G Pad 8.3 Android Development] oneandonlycore:
This what i was thinking ... but after 2 hours of watching the android animation Ive rebooted it.

Im running TWRP 3.0.2 I'll give it a try with 2.8.7.1 or 3.0.1
[G Pad 8.3 Android Development] dirlan2001:
Hmmmmm.... I wasn't aware of newer version.

:) running 3.0.2 now, no issues (same as before :cool: )

Cheers
[G Pad 8.3 Android Development] indian84:
Same here. TWRP 3.0.2 with SuperSU 2.52. No Issues here.. And I have stopped SuperSU to be updated from Play Store.
[G Pad 8.3 Android Development] Deltadroid:
First, make sure all the files you downloaded are ok by verifying with md5.

Next, I would try just rebooting to recovery and performing only a factory reset then reboot to the system and see if that fixes it.

If a factory reset doesn't work, try flashing the rom over again without gapps to see if that helps.

TWRP 3.0.2 should be fine.
[G Pad 8.3 Android Development] dirlan2001:
AFAIK GApps are included and based on OpenGApps.... Personally I install the latest OpenGApps Full afterwards, and some single GApps from your DeltaGApps thread

Cheers

Hi all, i am doing my sons gpad after over a year when he first got it.

I left it on 4.4.2 stock as was very hard to get twrp to work.

Finally today i got down to it and rooted and twrp working.

So wanted a new rom for him and installed this, but no longer rooted which was a pain in teh beginnning to do on this device.

I see link for supersu but how do i actually root this on this rom, i tried kingoroot as before, but now i get a security warning and will not root.

Thank you
[G Pad 8.3 Android Development] tmihai20:
[MENTION=4531421]Wingchundub[/MENTION], since you have a custom recovery already, you should download SuperSU 2.52 and install it in recovery. Any other SuperSU version will half-brick the tablet. You do not need to user towelroot or kingoroot, this is a custom ROM, you just need to flash a SuperSU version compatible with it.
[G Pad 8.3 Android Development] Wingchundub:
I have been working on this for hours, my head is spinning lol.

I've forgotten it is a custom rom and no need to root haha :eek:

Thank you kindly, that worked a treat :good:

Finally can give him his tablet back now.

Alright guys, I screwed up somehow. I was on 20f and installed twrp without issue. I followed the directions and installed the ROM but now I'm getting Secure booting error, cause boot certification verify. What should I do next? What did I screw up?
[G Pad 8.3 Android Development] indian84:
Read through few pages back. You need to boot in recovery, wipe everything except internal storage and SD card, flash ROM and SuperSU 2.52. Do not flash any other version of SuperSU.
[G Pad 8.3 Android Development] SeanPlunk:
How do I boot back into recovery? No button combo is working.

After a half a dozen soft bricks, I realized that copying the old build.prop over the existing one would render the current version unusable. Use these 2 files to replace the existing ones in order to make the tablet to see WiFi channels above 11. I am also attaching the original files as well in case you mess it up. Would you like to have a TWRP flashable zip? I could make one that could also back up the existing files. These archives have to be unpacked somewhere and you have to copy build.prop to /system and WCNSS_qcom_cfg.ini to /system/etc/wifi over the existing files.

setup wizard stopped working

Hi guys,

I'm new to flashing ROMs. I tried installing the 2016-05-05 update multiple times yesterday but i kept running into a problem where the setup wizard would stop working after optimizing the apps the first time. This leaves the tablet unusable as the homescreen wouldn't even load. I've installed CM12.1 successfully so it must be the ROM. Any idea how this can be fixed?
[G Pad 8.3 Android Development] Darkmasterhk:
it's also broken for me (guess it only happens on a complete clean flash),

afterwards you can update to 05.05. just let it boot and finish the setup first

[MENTION=4297659]adrianom[/MENTION] can it be related to google play-services?

after updating to 05.05. I got an notification telling me to update play-services so that all apps can work

Yes , u can flash both the same time. Select the ROM first, then add another 'zip' in the row. Updating in the Playstore isn't needed. Maybe just if the Playstore indicates a newer version for YOUR device is available.

[MENTION=4297659]adrianom[/MENTION]: can you please fix one little issue (the tablet does not see a 2.4 Ghz WiFi AP on channel over 11)? I will make a commit if it is needed, but I cannot find where build.prop is. The line in build.prop that has ro.wifi.channels= must be ro.wifi.channels=14. Also, a line must be uncommented in WCNSS_qcom_cfg.ini and it must look like this: gCrdaDefaultCountryCode=UK. I do not know how to have these 2 lines modified on GitHub, I hope you will not get upset with me asking this, I can keep modifying by hand these 2 files on every release.

[G Pad 8.3 Android Development] tmihai20:
Copy on a PC anything you have on it and try formatting it with the SD Formatter from HERE. I had a lot of issues with the stock LG Lollipop, but I had the unmounts issue only once since using this ROM. However I was able to get it mounted after pulling it out of the slot and inserting it again. Choose Format Type - Full (Erase) and Format Size Adjustment - ON in Options just to be sure. The full format will take a while, but it should help. Report back here to tell us if it worked.

[G Pad 8.3 Android Development] indian84:
You have to use custom launcher like nova to remove search bar.
