Forget it, problems with that specific SD card started to appear in my other tablet now!
[G Pad 8.3 Original Android Development] DSC05:
What kind of problems?
[G Pad 8.3 Original Android Development] darkvoid_66:
Could not write data on it anymore. Reading errors. I guess that SD card is broken.

I know stupid question but can this be flashed on the T-Mobile LG g pad f 8? Like is there a HUGE difference from this variant?

How much time does your battery usually last?

Today this isn't looking good:

4 hours of screen
[G Pad 8.3 Original Android Development] darkvoid_66:
I was using cm-12.1-20151006-UNOFFICIAL-awifi.

I downloaded cm-12.1-20151124-UNOFFICIAL-awifi went into recovery, flashed this ROM and cleared cache and dalvik cache and rebooted, as I've alwasys did when upgrading in the past.

But my pad is now stuck on LG boot screen.

Any ideas why?!
[G Pad 8.3 Original Android Development] darkvoid_66:
Can someone help. I cannot go into recovery!

When I press the key combination to go to recovery as I have done many times I get the factory reset menu press power 2 times and go back to LG screen.

sIt's Stuck

What can I do to recover tablet?!

can someone install an app called "Sensors Multitool" and give me screenshots of the sensors?

sensors are not working for me on cm13.0, after an update to them, and we are trying to find the culprit.

many thanks.

[G Pad 8.3 Original Android Development] darkvoid_66:
Thanks for your reply. But I cannot boot my tablet it does not load OS and does not load recovery...

Can I do the dd method?
[G Pad 8.3 Original Android Development] deepongi:
then you are kind of scre*** .. you need to start over and flash 4.4.2 kdz.. theres plenty tutorials in how to flash them.

if need any more help, send me a PM, and we will speak in our native language, to be easier.

Still getting random SD unmounts.

Other than changing the card is there anything else I can try?
[G Pad 8.3 Original Android Development] cronot:
If you want it to work without any drawbacks then no, there's no option.

You can use the attached script (not my work - I've modified it slightly from this) and set it up so it runs at boot, either via init scripts (beware you'll have to put SELinux on permissive for that) or via a Tasker Device Boot profile. The drawback to it though is that, while you won't see SD unmounts anymore, battery usage will suffer a lot - it will go down by about 8% per hour with the device on stand-by. So you'll really want to keep it plugged in a power source as much as possible.

However, I want to further corroborate previous reports (like this one) that the G Pad will work with no SD card unmounts if you get a Samsung Evo+ SD Card - I got mine last week, disabled that script I was using, and it has been working wonderfully ever since without any SD unmounts. Just take care to get the Evo+ (plus) model - there's also a "non-plus", plain "Evo" model, but these WILL have SD unmount problems (first-hand experience).

[G Pad 8.3 Original Android Development] jesuita:
I'll check those SD cards. Between that and huge battery loss the choice is clear.
[G Pad 8.3 Original Android Development] pnin:
Before everybody runs to buy Samsung Evo+ cards, I want to say that I permanently run a Sandisk Extreme 16GB card with this ROM on my V500 and never experienced any unwanted unmounts.

FYI, users of A1 SD Bench app are complaining about the performance of Evo cards. Check the app itself, too, it might help pinpoint whatever is wrong with your cards -- my hunch is lack of compatibility of larger capacity cards...

EDIT: commenting on ncguy68 below, I had to add that I've been on KK bootloader ever since I moved to CM12.1, as recommended by the dev.

[G Pad 8.3 Original Android Development] ncguy68:
I always got sd card dismounts while using the kit kat boot loader. They never happened with the jelly bean boot loader.

can i use this rom as primary rom for multirom?

the kernel have the kexec hardboot patch?

in multirom thread in the download section are the:

Kernel w/ kexec-hardboot patch (CM 12.1): kernel_kexec_v500_cm121_20150608.zip

but seem an old version 2015-06-08...

if the default kernel don't have the patch can i use this or are a too old version?
[G Pad 8.3 Original Android Development] vedko:
Since you posted this question in 4 different threads and got no answer I'd day make a backup and try your luck.
[G Pad 8.3 Original Android Development] Deltadroid:
This kernel does not have the kexec hardboot patch. I would also recommend not using an old kernel from cm12.1 with this ROM, because it might not boot up.

Fefifofum posted a link to his kernel source on the op so you can see which patches are included.

---------- Post added 27-05-2016 at 12:00 AM ---------- Previous post was 26-05-2016 at 11:57 PM ----------

It's the sdcard, not the bootloader. Different sdcard drivers might help reduce the unmounts for a little while, but I'm afraid you need a newer sdcard to completely fix the issue.
[G Pad 8.3 Original Android Development] pnin:
Sorry for reviving this rather old thread, but the ROM download link in OP is dead. I googled extensively but got nowhere...

I still have the 20150921 build archived, but I missed the latest 20151124. Can anyone provide a working link, please?
[G Pad 8.3 Original Android Development] lentm:
This rom is the best for me so far. Tried every single rom, didn't work too well.

Thank you so much!!
[G Pad 8.3 Original Android Development] fefifofum:
New build released

...with lower lcd backlight values, so we can get a darker display if we want to. The "faster booting" change should be inappreciable (so no placebo here). ;)
[G Pad 8.3 Original Android Development] Deltadroid:
The "screen bleed" that I used to have on startup is now completely gone. All of the edges of the screen are now completely black. Really good job!

The change you made to the lcd backlight settings is a noticeable improvement.
[G Pad 8.3 Original Android Development] Jeff_57:
Hi.

I have recently tried several 5.1.1 ROMs. I got disappointed.

The bugs (SD card, black screen) made me revert to 5.0.2 which I found more stable.

I reinstalled this one and finally got a stable system.

Kudos for this work.

No issue so far. Brilliant !

New build released

...with several bluetooth related fixes. Now we use a real bluetooth address taken from misc partition, so even a wipe data won't change your bluetooth address. You will need to pair again your bluetooth devices, but it will be for the last time... Other bluetooth fixes are related to audio devices: now you'll be able to use bluetooth headsets in skype calls, or you'll be able to use your bluetooth mic to do voice searches in google now. Thanks a lot [MENTION=5227588]Deltadroid[/MENTION] for his help with the testing.

I cannot keep wifi on during sleep even though I set it right. Any possible fix or cause?
[G Pad 8.3 Original Android Development] fefifofum:
I don't know why you are having this issue, it works fine here (both, suspending wifi and keeping it on during deep sleep). Can anyone else confirm about it?
[G Pad 8.3 Original Android Development] Willisme1:
I'm having no problems with WiFi staying on during sleep on my fresh install.

Also, has this build got the latest adreno drivers built in? I'm not sure how I'd go about checking them.
[G Pad 8.3 Original Android Development] fefifofum:
Yes, adreno drivers are as updated as the kernel of nexus 4 and nexus 7 (2013), look:

https://github.com/awifi-dev/android_kernel_lge_awifi/commits/cm-12.1/drivers/gpu/msm

https://github.com/CyanogenMod/android_kernel_google_msm/commits/cm-12.1/drivers/gpu/msm

And we use the latest adreno vendor files from palman 5.1:

[G Pad 8.3 Original Android Development] Willisme1:
Thanks! Brilliant ROM, glad to finally have the back camera working without being stock.

I'll update you with any problems I find (if I ever find some :p).
[G Pad 8.3 Original Android Development] Deltadroid:
I was just testing out the cm12.1 theme engine in this ROM and it is finally working as expected. I can reboot and the theme is still applied. ☺ I have never been able to get that to work before after rebooting the device. ?
[G Pad 8.3 Original Android Development] luisbraz:
Nice work. I'm using the 0617 version and I see now that there is a update (0620). I suggest you to publish a change log, like others do. One more time, nice work and thank you.

EDIT : Sorry! I've got to go to the ophthalmologist! ?
[G Pad 8.3 Original Android Development] Xoxu:
Nice work again but for me doesn't work...

Clean install of the 0619 and redkernel awifi r021 with the specific gapps

Most of the issues are a dismount of the sdcard but also a bad WiFi stability

With the official cm12.1 and redkernel r020 I have no issues at all.(the r021 with official cm12.1 make me some issues too)

It's a pity because the blacklight change is what I want...

Thank you again and say me if you want more info

Xoxu
[G Pad 8.3 Original Android Development] Cal:
But the kernel in the ROM is what makes this build so special. You don't need any other kernel. Have you tried to install only like the builder states...ROM + Gapps? No additional kernel needed.
[G Pad 8.3 Original Android Development] Xoxu:
Hoho!!

Maybe I am not a so good android user....

I didn't understand this part...

I try tomorrow, maybe a better result...

Oser things I don't understand, all the correction make in the official cm12.1 are in the unofficial or it's a new base and the development stay different?

Thanks to light my mind...

Xoxu
[G Pad 8.3 Original Android Development] fefifofum:
I'm only responsible for what is posted in this thread, so if you use a different kernel I cannot look at the bugs you are having. Please only report your bugs if you are using the builds from this thread (kernel included).

It's a new base and the development stay different.
[G Pad 8.3 Original Android Development] Xoxu:
Yes I didn't understand the story of the kernel but now yes so no problem, I try your rom again soon as possible.

Thanks
[G Pad 8.3 Original Android Development] gordonbennet:
Lovely rom. Thanks for all the hard work. Should I use redkernel with this or is the stock kernel fine?

Also, if I came from stock 4.4.2 do I need to flash 4.4 bootloader?
[G Pad 8.3 Original Android Development] ThunderBolt_BR:
Use Stock Kernel to support the developer and to have the possibility to inform any bug you face.

This ROM, as it is stated at the first post, is meant to be run on a 4.4 base. So, if you are coming from stock 4.2.2 you must flash 4.4.2 bootloader: Just seach for the flasheable zip done by [MENTION=4517918]fefifofum[/MENTION].

[G Pad 8.3 Original Android Development] fefifofum:
The stock kernel is fine (did you expect me to say otherwise?). If you come from stock 4.4 I guess you already have 4.4 bootloader...

**************

New build released. I removed all IRRC files and configuration (QuickRemote is gone too) since I don't think we can fix it. The gpad uses sw irrc driver, which needs changes in audio and media libraries, and we don't have that code. Other LG devices use hw irrc driver, that's why the solutions for LG G2 and G3 do not work for us.
[G Pad 8.3 Original Android Development] lentm:
This doesn't happen every time. It usually happens when

my gpad goes to sleep while uploading something big to cloud.

I see gpad reconnects to wifi and upload failed notification when it wakes up.

I'm currently using 5ghz wifi connection and my phone doesn't have the same issue.

I also did fresh install and everything else works great.
[G Pad 8.3 Original Android Development] Deltadroid:
Try setting the kernel to permissive mode to see if it fixes the upload problems. This would narrow down the problem.

https://www.androidfilehost.com/?fid=95916177934554765
[G Pad 8.3 Original Android Development] fefifofum:
Please, attach a logcat and dmesg so I can see what's the error. If you don't know how to do that, you can use this app.

I don't think that's the problem, and it's better to wait for logs or try yourself to reproduce the bug. Otherwise we are just doing blind tests...

Is it advisable to switch the selinux mode to permissive for general use?

Dad is loving the new tablet especially with this rom
[G Pad 8.3 Original Android Development] fefifofum:
It is NOT advisable to switch the selinux mode to permissive, and there is no need to do it. This rom doesn't have sepolicy denials, so it's safer to keep selinux in enforcing mode.
[G Pad 8.3 Original Android Development] mackeev:
I can confirm this! Finally, I got what I've been looking for. Thank you very much, fefifofum! I've switched (dirty flashed) from official cm12.1, and it seems like I got an absolutely new device.:good:

I'm using SlimKat rom but I'm don't remember which bootloader is installed: 4.2 or 4.4 ? How can I know?

I'd like to try this rom but I don't know if I have to use the official or unofficial one according to which bootloader I have...

Thank you for you help.
[G Pad 8.3 Original Android Development] fefifofum:
Official cm-12.1 is adapted to 4.2 bootloader backlight, and this rom is adapted to 4.4 bootloader backlight. I don't know about SlimKat, ask in that thread. You shoud also check the bootloaders thread.

If you are unsure which bootloader you have, just flash it again.

Reporting 2 issues:

1. Auto rotation: auto rotation didn't work after flashing

a. Was running this ROM, but decided to try out stock 30A ROM by skin1980 (http://xdaforums.com/lg-g-pad-83/development/rom-stock-rooted-lollipop-rom-int-g-pad-t3079312)

b. Flashed 30A ROM via TWRP 2.8.6

c. Auto rotation worked

d. Decided to come back to this ROM after hearing the gamma change

e. Upgraded TWRP to 2.8.7

f. Flashed this ROM (dated 6/24) and Gapps (wiped data, cache, and system)

g. Auto rotation didn't work (even after rebooting a few times)

h. Flashed the latest official CM 12.1 nightly (wiped cache)

i. Auto rotation worked

j. Reflashed the ROM from step f (wiped cache)

k. Auto rotation worked

2. Battery saver mode: system lags even after started charging

a. Was playing Plants vs Zombies 2

b. Low battery warning pop up

c. Turned on battery saver mode

d. Game became very laggy

e. Finished game and exited out to launcher (default launcher)

f. Plugged in USB cable and started charging

g. Battery saver mode turned off (red bars disappeared)

h. However, G Pad was still somewhat laggy (tried Chrome and Google News)

i. Did a soft reboot

j. Lags disappeared
[G Pad 8.3 Original Android Development] fefifofum:
I followed your instructions and installed V30A to see what was the rotation error (nobody gave me logs). The good news is that I found the error and fixed it for next release. About the battery save mode, it shouldn't be confused with the power profiles. Battery save mode is present in all lollipop roms, but cyanogenmod also has power profiles (which are confusingly called "battery mode"). When battery save mode is enabled in cm-12.1 (red bars appear), it automatically changes the power profile to "power save", which is really meant to save battery and not for gaming (thus the lags). So when you start charging and disable battery save mode (red bars disappear), you have to manually change the power profile back to balanced, otherwise it stays in power save and that's why you get lags. Power profiles can be changed from Settings > Battery > Battery mode, but you could also add the "battery mode" tile to notification drawer, that way you really know what power profile you are using at each time (and change it if needed).
[G Pad 8.3 Original Android Development] cant0nese:
Thank you for the explanation and all your hard works!
[G Pad 8.3 Original Android Development] fefifofum:

Is it possible to include network monitor applet in notification bar?

To me this is the only missing feature to this quite perfect ROM
[G Pad 8.3 Original Android Development] fefifofum:
No, that feature is not present in CyanogenMod. Maybe you can find some app to do that, but no idea (maybe xposed?).
[G Pad 8.3 Original Android Development] ol31:
It is included in a few cm based rom like candy, résurrection remix, ...

Never found such a simple app.
[G Pad 8.3 Original Android Development] rom169:
app icons

I upgraded to version 20150627 today and screen rotation works now. Very nice ROM, thank you!

The only issue: When I reboot the device, the app icons of apps moved to SD card disappear from home screens. Not sure if this happened with older versions, as I'm new to this device and ROM.

regards

rom69
[G Pad 8.3 Original Android Development] Deltadroid:
Does the app icon still disappear from desktop if you add the app icon to the desktop after the app is moved to the sdcard? Maybe you need to create new shortcuts on the desktop after you move the app to the sdcard.
[G Pad 8.3 Original Android Development] rom169:
I created the icons several times. After every reboot they are gone for all apps moved to SD card. If I move the apps back to internal storage, the icons survive the reboot.

regards

rom69
[G Pad 8.3 Original Android Development] fefifofum:
That's probably an upstream bug. If you really need your apps in the SD card, you could try a different launcher to see if that solves the problem. But my advise is don't move apps to SD card, they are better in internal storage, use the SD card for your files and internal storage for your apps.
[G Pad 8.3 Original Android Development] Deltadroid:
Apps will startup faster and run smoother when they are installed to the faster internal memory.

The launcher must be drawing the desktop before the system can load the apps that are moved onto the slower external sdcard.

I remember that widgets were always disabled for apps that have been moved to the sdcard. The same rule probably applies to shortcuts of apps that are moved to the sdcard. I agree with fefifofum's recommendation.
[G Pad 8.3 Original Android Development] Shimaran:
After flashing the rom and the v50020D bootloader, I cannot enter TWRP again because I have the following message instead :

[G Pad 8.3 Original Android Development] Shimaran:
Damn, I just did that before to be able to flash the ROM :D

So, when I'm back with KK stock rooted and with TWRP recovery, is there a particular order to flash the V50020D blootloader (before or after flashing the ROM) ?
[G Pad 8.3 Original Android Development] fefifofum:
What recovery did you have installed? Official TWRP is recomended. You can use this app to flash the recovery again, that will probably solve your issue.

There is no need to install KK stock. Install official TWRP and V50020D blootloader, reboot to recovery, then flash rom + gapps.
