Hi Jesuita,

Deltandroid said to use 5.1 (I was using 5.0.2 which was wrong for this later version). Found the best results with the 4.2.2 base and Red's 15 Kernel...also I use Infected's 12.1 nightlies.

Good luck!

[G Pad 8.3 Android Development] gordonbennet:
Is this right? I got a used g pad 8.3 v500 with stock kitkat lg rom on it. To use CM 12.1 I need to put on TWRP and ideally use 4.2 kernel base. Then flash CM12.1 + 5.1 gapps. Is a custom kernel recommended? Can I use the 4.4 kernel base somehow? Thanks
[G Pad 8.3 Android Development] Cal:
I don't think a custom kernel is recommended, but more users of 12.1 use one.

As to the boot loader, if using the later TWRP one may get screen dimming...but that only occurs booting into recovery. (at least for me)
[G Pad 8.3 Android Development] Feed Me:
To people who are using a custom kernel: which kernels are compatible with this ROM? I saw that RedKernel works, but what version of it?

Thanks in advance!

Great work infected :)

How do I get root in this ROM?
[G Pad 8.3 Android Development] ledabe974:
Go to develloper option and check root access
[G Pad 8.3 Android Development] Cal:
12.1 seems the best at memory usage ROM I've used...& I've tested a lot!! :) Still has a few bugs using Maxthon browser, but that could be browser & not the rom. Everything else seems solid. Putting on standby is fantastic in the WiFi shutting down & saving a ton of memory for me - I'm not syncing anything testing. Very pleased with all, so far.
[G Pad 8.3 Android Development] meanoc:
Agree 100%. Very solid rom :good:
[G Pad 8.3 Android Development] bland.life:
Got this installed with the 5.1 PA Gapps.

Running smoothly.

The only problem that occured is that the device turned off 2 times on first boot.

During the long optimizing app phrase.

I think it got too hot so I hold the device back facing the fan close and it managed to pull through to the long first boot.

Reporting issue about - screen going blank

I have the same issue reported at http://xdaforums.com/lg-g-pad-83/development/rom-official-cyanogenmod-12-t3026647/page23

Screen goes blank. Hitting the power button turns the backlight on and off but nothing shows up. The only way to get anything working again is to force a reboot (hold all buttons).

I tried Mr infected_ 's solution 4x with same rresult (by wiping /system & /data and do not restore your google stuff. you can add your account, but dont restore things. ).

I restored back to CM12 last monthly build and no issues so far (to narrow down the symptom and show my V500 works.).
[G Pad 8.3 Android Development] Deltadroid:
Did you try a factory reset (which wipes /data and /cache) and not restoring anything?
[G Pad 8.3 Android Development] jimmys_:
I experienced the "screen going blank" issue from versions 4/8 to 4/11 nightly builds.
[G Pad 8.3 Android Development] Deltadroid:
I think this is related to a memory leak, but im not certain.
[G Pad 8.3 Android Development] jimmys_:
Yes. I tried wiping data/cache as recommended. I also tried wiping everything, including system plus twrp recovery with no luck. I then restored back to CM 12 once I felt I am not going anywhere with 5.1.

The ROM installs and is very smooth. The screen will intermittently go blank about 10 - 20 minutes of continuous use with reading articles, news, browsing, etc.
[G Pad 8.3 Android Development] Deltadroid:
Are you using the 4.2.2 bootloader?
[G Pad 8.3 Android Development] jimmys_:
Yes, i'm using 4.2.2. I was originally at 4.4.2 but downgraded to 4.2.2 before installing this ROM. When I switched back to CM12, I stayed at 4.2.2 (and did not have to use Mani kernel, which I used to use when I was at 4.4.2).
[G Pad 8.3 Android Development] Deltadroid:
I wonder if this problem is related to the compiler (sabermod).
[G Pad 8.3 Android Development] jesuita:
If by blank you mean the screen going black but visible that it is on it happens to me too with infected 5.0.2 from time to time.

Also with 4.2.2 base. Wonder what it is oO
[G Pad 8.3 Android Development] nigelhealy:
Trying this we if any better than AOSP 5.1

I have lost WiFi 5Ghz.

Auto rotation isn't working. Yep toggled it in settings to allow.
[G Pad 8.3 Android Development] Deltadroid:
Reboot
[G Pad 8.3 Android Development] nigelhealy:
Thanks. Got back auto rotate.

Still no 5Ghz. Its working in hardware as has it on other ROM.

Is this kernel or firmware or ROM cause ¿
[G Pad 8.3 Android Development] Deltadroid:
Most likely it's a kernel issue.
[G Pad 8.3 Android Development] Katmeat:
This ROM is awesome! Everything is working great for me, including 5Ghz wireless. I'm running Red Kernal 16, and no problems at all.

I saw that the latest Consumer Report reviewed 8" tablets, and the Gpad 8.3 finshed in last place, likely due to poor battery performance. All that I can say is that CR obviously never heard of Mr. Infected, as I see nothing on that list that I would trade my beloved Gpad (running this ROM) for. Thank you Mr. Infected, for you superb work! An additional donation is forthcoming.
[G Pad 8.3 Android Development] nigelhealy:
So for this rom do I use red kernel r016 aosp or r016?

Edit: whilst it's not obvious eventually I saw it say CM or AOSP so flashed RK16. I also added the permissive mode zip.

I still don't have WiFi 5Ghz so that's a hint its not CM12.1 kernel cause. I have on my phone tried CM12.1 of similar date and it has 5ghz so puzzled.
[G Pad 8.3 Android Development] ThunderBolt_BR:
I am running this ROM on my V500 since it's first nightly (currently with 0412). I can see 5GHz Networks with WiFi Analyzer app but I do not have a 5GHz AP to test the connection.

I had also a problem of the tablet freezing when pausing a youtube video, but that was solved by simply wiping youtube's cache and data. All that is left is the support for our beloved OV5693 back cam module...

Hi [MENTION=1077833]infected_[/MENTION],

Did you also use the new Qualcomm Adreno drivers from Mako on the process of merging Android 5.1.0_r5 sources? I don't know if it is a placebo effect or not, but scrolling on 20150416 nightly is even smoother than on 20150410. What was already good became even better.

Thanks a lot!

[G Pad 8.3 Android Development] ukguy115:
Thanks for the ROM.

Tried the super alpha xposed its a no go right now if anyone interested.

Can connect to 5ghz networks just fine.

Everything working good here.

Freeze during first boot

I have flashed the latest unofficial nightly and slim_mini_gapps after wiping system, data and cache in TWRP. I've had CM11 unofficial by [MENTION=1077833]infected_[/MENTION] on it before.

Now the tablet freezes some time after boot, during the CM boot animation, resulting in a black screen.

Went back to 0425, it works fine.
[G Pad 8.3 Android Development] Katmeat:
Likewise for me on these latest nightlies. I have tried downloading and installing the 4/28 nightly twice, with the same poor result, with tablet failing to boot. Flashing back to the 4/25 nightly works just fine.

Thanks for posting - new build is on the site! I had the same boot fail issues with prior builds and will update with install results in a bit.

EDIT:

Success! For what it's worth, I updated from TWRP 2.8.5 to 2.8.6 (here) prior to flashing the latest (2015-04-30). Will play more later, but already noticing that magnetic screen off works (think I saw others stating it hadn't in prior builds). Great job, Infected - thanks again!

screen goes black

I have a weird problem that happened couple of times with 0425, and keeps happening with 0503 as well: sometimes the screen goes black, and the device freezes - not entirely, because there are still some haptic feedback coming, but it never wakes up. Only rebooting by holding the power button for 10-15 seconds helps.

I clean flashed 0425 (full wipe), then dirty flashed 0503 over it (cache+dalvik). Not using any mods.

iPlayer issue

Ok I'll try again as previous post very unhelpfully moved by post to the seemingly abandoned Q&A area. I'm trying to report a bug here not as a question.

There's a bug when playing video from the BBC iPlayer app. When playback starts, the screen goes to sleep with the audio still playing in the background. This may be to do with the optimisations done to this ROM specifically as it doesn't occur with other CM based ROMs. Could be something else? Anyone else have the issue or does _infected_ know of the issue and is there a fix planned? Thanks for a great ROM, appreciate all the work gone into this.

[G Pad 8.3 Android Development] scaramonga:
Yup, having the same problem, updated to 05/05, and still the same. Screen will go black randomly, and reboot is only way to get back. Can happen with any app, for example, load youtube, bam!, black screen. When I reboot and load same app again, its OK? My podcast player is the worst. I start the app and it plays fine, a minute later it stops. I open cover to find the black screen, reboot required to fix.
[G Pad 8.3 Android Development] mekoneko:
The app that this happens most often for me is Feedly. It's not a hard crash though, music still plays in the background.

5Ghz WiFi

Hello. Does 5Ghz WiFi work for anyone? I ran infected_'s CM11 builds on my G Pad and it worked great. So far, any CM12.1 build I try seems to be 2.4Ghz only. I do not even see the "Wi-Fi frequency band" option in Settings->Wi-Fi->Advanced anymore. Thanks in advance.
[G Pad 8.3 Android Development] Katmeat:
I have no problem connecting to and using 5Ghz wireless.

Katmeat
[G Pad 8.3 Android Development] julesism:
I figured my issue out... I use channel 153 on my 5Ghz network. In the past, I would flash mani's kernel. Without that kernel, my device does not "see" that 5Ghz channel :/ I tried Rick Rolls RedKernel. For now, I'll keep my GPad on my 2.4Ghz network since it's the only device with the problem. If anyone has any suggestions, I'm all ears.
[G Pad 8.3 Android Development] deepongi:
have you tried another network/router (besides your own), on 5Ghz?
[G Pad 8.3 Android Development] julesism:
Hello. I can take it to work with me tomorrow and see what it sees. From what I can tell, it's not able to see (some of) the higher 5Ghz channels without ckret's Mani kernel. I fired up the Wifi Analyzer app from the Play Store and I can see channels 34 36 38 40 42 and 44 with one active network on 36 but that's it. A while back I sat down and went through every channel available on my router (Asus RT-AC68R running Shibby Tomato 129) and picked 153 because it provided the best signal and throughput across all of my devices. On Saturday when I rolled back to 12.0 with Mani kernel, it connected to my network on 153 just fine. I did clean installs of stock CM11, 12.0, and 12.1 and your builds of the same 3. Mani kernel worked when available. I'm tempted to learn about building roms/kernels. It would be interesting to look at his kernel and update it for 12.1 and/or see what might be different. This is not a deal breaker or anything urgent :) Just reporting my findings and open to chatter :) Sorry if this is a bit off-topic.

Hi,

I have a question about CM12.1-INFECTED nightlies and releases.

If I decide to wipe/factory reset my V500 to install a brand new CM12.1-INFECTED for example.

As only nightlies are available, I think that I could update to next nightlies without wipe/factory reset.

But what about any release or Stable CM (M version ?) when I'd want to update from a nightly to release ? Will it possible without wipe/factory reset ?

Thanks !
[G Pad 8.3 Android Development] Cal:
I've tried up-dating from a CM "stable" to a nightly just overwriting and cleaning none of the catches and no through cleaning of anything...but it wouldn't install.

Seems it must be stable CM to stable CM, & experiment (nightly) CM to (nightly) CM, and you could use *any* CM ROM, infected's or anyone eases build as long as it's a 'nightly' & the same version & do this...but you can't go from a 'stable' to an un-official ROM. At least that's what occurred with me. May sound a bit confusing...but that's the best I can explain it. :)

Hey [MENTION=1077833]infected_[/MENTION]

I am running 20150618 atm, and it is affected by the black screen bug (screen turning black, especially often if using Google Play Newsstand, sleep / wakeup via power button works, but needs reboot for display to show anything again). I am downloading and upgrading to 20150707, but not planning to use custom kernels.

- are you aware of this bug?

- is it expected to be fixed by you or CM devs?

Great ROM BTW, smooth performance!
[G Pad 8.3 Android Development] deepongi:
i am not suffering from the black screen bug... have you tried to flash stock kdz 4.2.2 and then upgrade your way back to CM12.1 ?

you could try also a clean install with one of the latest builds.
[G Pad 8.3 Android Development] gkkovacs:
Well many people have reported it, so maybe you could try reading the news with Google Play Newsstand for a few minutes? It's the only app that triggers the bug for me.

I have come from your CM11 ROM via clean install in May, dirty flashing CM12.1 since then. The black screen bug started to appear early June builds IIRC, but it's possible it was there before that.

Clean install is a PITA, but I can try it with a nandroid backup to check the Newsstand app. Will report back on this.
[G Pad 8.3 Android Development] Deltadroid:
The black screen bug is caused by the new color management code added to the cm kernel and rom. The patch needs to be reversed in the kernel and the rom needs to use the previous color management method.

Black screen after 20 minutes testing while watching a video in Facebook browser. I guess redkernel (r021) is afaik still the only fix for black screen issue on cm12.1. I wonder if this couldn't be fixed on stock cm 12.1 branch, because I'm not absolutely satisfied with performance on redkernel.
[G Pad 8.3 Android Development] fefifofum:
Builds using my sources shouldn't have the black screen issue, so I guess it is caused by the "optimizations" mentioned in the post you quote.
