I know it's weird but that's the key on the v30b I'm using :o

Now that I think about it it does look wrong though.

Yeah, scratch that [MENTION=5227588]Deltadroid[/MENTION] it's been a long day and I think I funked something up when I was editing that key, oh boy, I need to get away from my screen.
[G Pad 8.3 Original Android Development] Deltadroid:
at first, I though it was just a difference in case sensitivity, but now that I look closer, it is actually spelled differently than the stock key.

# Enable CRDA regulatory support by settings default country code

#gCrdaDefaultCountryCode=TW

currently, it is commented out on this rom.
[G Pad 8.3 Original Android Development] fishears:
I've decided to blame the itty-****ty font in Root Explorer's text viewer - not much of an excuse but I'm sticking to it now :eek:

It is generally commented out by default, I think its just there for users to be able to override without changing their country setup elsewhere.

EDIT: sorry to everyone for my ramblings
[G Pad 8.3 Original Android Development] Deltadroid:
since the key is commented out, it makes me wonder what the default is and if that default matches our current county code.

Edit: [MENTION=4517918]fefifofum[/MENTION], since the commented out key is set to the Taiwan country code, I have a feeling that the Wi-Fi blobs in this rom default to Taiwan settings and the only way to make sure the country code is correctly set for the BR region is to manually set both keys.
[G Pad 8.3 Original Android Development] fefifofum:
That ini file is the one responsible for wifi country, not other blobs. The setting gCrdaDefaultCountryCode is commented out in LG's V30a and V30b, so the value is not forced and you can choose the wifi region from advanced wifi settings. The problem is that choosing wifi region from cm-12.1 settings isn't working properly (I have to look into that), so a workaround for now could be using gCrdaDefaultCountryCode. About gStaCountryCode=BR, these are the possible values:

# KOREA = KR, USA = US, JAPAN = JP, BRAZIL(LATIN AMERICA)/EU/others = BR

So BR is for every country except Korea, USA and Japan. In your case, you could set this: gCrdaDefaultCountryCode=GB (uncommenting the line, of course), which is the default value for Europe.
[G Pad 8.3 Original Android Development] Deltadroid:
Yes. Since the CM12.1 wifi ini is already setting the default country code to "BR" with gStaCountryCode, I thought we should also manually set CRDA to "BR" as well. I don't know what the actual defaults of those keys are (gStaCountryCode and gCrdaDefaultCountryCode) if they don't get set in the wifi ini file. The ini sets gStaCountryCode, but not gCrdaDefaultCountryCode, and they should be both set to the same country. I was thinking that since our wifi files are from a stock Taiwan ROM, then the defaults of those country code keys are probably not set to BR since they are not both defined in the wifi ini.

Edit:

gCrdaDefaultCountryCode=BR (not GB) *typo above*

Edit 2:

The setting gCrdaDefaultCountryCode is commented on the stock 5.0.2 ROM, but uncommenting it out and setting it to "BR" fixes the wifi channels in Europe (even if gStaCountryCode is already set to BR). Since that setting is commented out on the Taiwan ROM, then I believe gCrdaDefaultCountryCode is automatically defaulting to TW without having to set the value of that key in the wifi ini. That is why manually changing the value of gCrdaDefaultCountryCode to BR fixes the european wifi channels, even if gStaCountryCode is already set to BR.

Edit 3:

Setting proper regional CRDA support also seems to improve the Wi-Fi signal from dropping out when wmm power save delivery is enabled. I can now re-enable wmm power save mode on the router and Wi-Fi is not disconnecting. CRDA support also controls some of the Wi-Fi voltage.

Edit 4:

Enabling WMM power save is still causing the Wi-Fi to drop out in sleep mode. CRDA support did not fix that problem after all.
[G Pad 8.3 Original Android Development] fefifofum:
New build released

with updated blobs and fingerprint to V50020B and several wifi related changes. Wifi region is now managed from the kernel, it will find and set your region, so no need for the user to do anything. This will also fix the access to some high number wifi channels.
[G Pad 8.3 Original Android Development] Deltadroid:
I have enabled WMM Automatic Power Save Delivery(APSD) on my router to test if the wifi speed drops when the device goes to sleep. The problem seems to be fixed now! After enabling APSD, I just had to reboot the tablet and it is working as expected. The wifi definitely seems better now with power management.
[G Pad 8.3 Original Android Development] Deltadroid:
I also wanted to mention that since Wi-Fi power management is properly working now with the latest rom, I can now connect with a link speed of 72Mbps on 2.4 GHz. The link speed can not exceed 56 Mbps on an N network connection without Automatic Power Save Delivery (APSD) enabled. I was previously forced to disable that on the older ROM for Wi-Fi stability during sleep mode.

Great work!
[G Pad 8.3 Original Android Development] ThunderBolt_BR:
I can confirm that. 72mbps linked to a TPlink TL-WR841ND running DD-WRT. It used to connect only at 65mbps maximum before this build.

Excellent job [MENTION=4517918]fefifofum[/MENTION]!

[G Pad 8.3 Original Android Development] Deltadroid:
I have not experienced a single sdcard unmount since installing this latest rom update. The solution to the sdcard issue might have something to do with the fact that I performed a "fsck" on the sdcard to check for any file corruption. The fsck process fixed a directory on the sdcard that might have caused the sdcard to unmount. There have been no sdcard unmounts in my log for over a week now.
[G Pad 8.3 Original Android Development] kbluhm:
I did today, though it had been a while. :)
[G Pad 8.3 Original Android Development] Deltadroid:
Here is what I did to try and fix the sdcard:

1) turn off tablet and remove sdcard.

2) insert sdcard into card reader and place in Linux box

3) unmount sdcard (sudo umount /dev/sdb1) assuming sdcard is automounted as /dev/sdb1. Check dmesg for actual mount point of sdcard.

4) check disk (sudo fsck /dev/sdb1)

5) put back in tablet and turn the tablet back on.
[G Pad 8.3 Original Android Development] kbluhm:
Thanks for the tip! I will give that a shot when I am near my Linux box at home.
[G Pad 8.3 Original Android Development] nytral:
Here sdcard is fat, fsck is ok but still not mounting although it does just fine in recovery.

New build released

with camera hdr related fixes and small selinux policies improvements. Now hdr works in google camera and other camera apps (except stock camera app for unknown reasons). But there's still a small issue: if you are in hdr mode, then change to auto scene mode, then back to hdr mode and take a picture, hdr won't be working. As a workaround you can switch to back camera and then to front camera again, or simply restart the camera app. I will try to fix that issue, but since this rom is already pretty stable, I will update it less often and focus on cm-13.0 now.

S5? You mean Galaxy S5? This is not very useful for G Pad 8.3. I was just curious. There is some early cm13 build for LG L90, for example.

There is a AOSP 6.0 build in development section. I'm running it since 10 days. Pretty Stable.
[G Pad 8.3 Original Android Development] wizzardsk:
I installed it yesterday too. It looks nice, it just lacks some cm functions :)
[G Pad 8.3 Original Android Development] indian84:
Well you choose. Stable AOSP MM build or early buggy CM13 (If there is any) build. I tried CM13 on m OnePlus One and it is still very buggy.. I went back to Lollipop on OPO. But running AOSP MM on G-Pad.
[G Pad 8.3 Original Android Development] GXGOW:
I'm also running CM13 on my Oneplus One and it's already pretty stable. No idea what you're talking about.

Superb ROM !

This is a keeper <3

Were there any recent changes to the WiFi driver ? it appears to work more reliable than before ...

Thanks
[G Pad 8.3 Original Android Development] Deltadroid:
Yes, CRDA support is now working which has increased the link speed to 72 Mbps. :)
[G Pad 8.3 Original Android Development] yugoport:
Guys, sorry for disturbing, I always try to get the information by thinking it out but I have a doubt, does it matter if I jump one update? I mean last week I had a notification that I had an update but I hadn't installed the one that came earlier, the newest is sufficient right? I am asking this because lately I noticed that my tab stopped "seeing" my wifi network at home, all other devices can see the wifi network but the tab doesn't, any chance it has to do with jumping one update? Or is something else? Thanks in advance and sorry if it's a dumb question.

It's ok to skip an update and install the latest version. Most problems occur when downgrading, not upgrading.
[G Pad 8.3 Original Android Development] Ree-shar:
I wouldn’t use the updates that are being notified to you by the Pad. As far as I know (someone please correct me if I'm wrong!) they're different from the builds provided via this forum thread and don't include the WiFi fix which may be the reason why you're having problems.
[G Pad 8.3 Original Android Development] Deltadroid:
The CM Updater that is included in this ROM has been modified to install this unofficial ROM, not the official version. So, Yes, it is ok to use the automatic update application that comes with this ROM.
[G Pad 8.3 Original Android Development] Ree-shar:
Ah OK. I stand corrected! And actually very useful to know.

But why don't the updates have the awifi suffix? They just end in "UNOFFICIAL"...
[G Pad 8.3 Original Android Development] kbluhm:
This is an unofficial CM build.
[G Pad 8.3 Original Android Development] Ree-shar:
I understand that but what I have used from this thread - and fantastically good it is, I must say fefifofum, much better than the original 12.0 - ends in UNOFFICIAL-awifi not just UNOFFICIAL.

Why is the designation of the updates listed under "Cyanogenmod updates" different to that already installed?
[G Pad 8.3 Original Android Development] Deltadroid:
"awifi" is the official codename of our device, not "v500".
[G Pad 8.3 Original Android Development] Ree-shar:
Ah OK. Thanks!

with lots of kernel updates, back to polynomial color correction and other minor updates/fixes. Please, let me know if you find any difference in performance and battery life comparing to older releases.

Work in cm-13.0 is looking good, almost everything is working but it will take a bit longer than expected.
[G Pad 8.3 Original Android Development] Deltadroid:
With this latest update, it appears that Google's project butter now works as expected! I don't think I've ever tested a ROM for our gpad that had this working. Excellent job!
[G Pad 8.3 Original Android Development] kbluhm:
Agreed... no report on battery life yet, but right away I can tell you this is the smoothest this tab has ever felt. In every aspect. Not a placebo effect either. This thing is smooth.

Edit: after a full charge, I am at 82% with an hour of screen time... which is right about what I'd expect with my past typical usage... around 5 to 5.5 hours screen time. Two thumbs up!

[G Pad 8.3 Original Android Development] kbluhm:
It worked for me earlier on... maybe two months ago. I don't have it on me right now (yes, I save them all to external SD card) so I couldn't tell you the date I used, but that's useless at this point anyhow.
[G Pad 8.3 Original Android Development] jesuita:

Until MM is stable enough don't think it is that useless, cm12.1 works nicely on gpad.
[G Pad 8.3 Original Android Development] kbluhm:
By "useless", I meant whether it worked for me two months ago is somewhat useless info since it happened two months ago and would be stale info. I am still on the 12.1 builds and enjoying the heck out of them!

Hi,

I have randomly that screen switch off, but touch is still working. Its not a "real" switch off, cause knocking-on gesture does not awake screen again. I have to press powerbutton to switch off screen completely and again press powerbutton to reactivate screen.

This happened 5-8 times since I have installed 21th build. Previous builds without any issues (since 1-2 months now). Can anybody confirm this issue? Its not in a special app or just while typing, it happens randomly even once on homescreen.
[G Pad 8.3 Original Android Development] Deltadroid:
confirmed. I believe this will be addressed in next release.
[G Pad 8.3 Original Android Development] fefifofum:
New build released

with KCAL instead of PCC (fixes the black screen issue), and a small fix while switching power profiles. Hopefully this will be the latest build of cm-12.1 before having cm-13.0, but you never know...
[G Pad 8.3 Original Android Development] Deltadroid:
That was fast. :) Thanks, fefifofum. I did not have any bsod with the last release, but I did reboot into recovery often, which may have been the reason why.

You can update from AFH.

---------- Post added at 01:25 AM ---------- Previous post was at 01:18 AM ----------

I am currently testing if the External Storage read ahead value has any effects on the frequency of the sdcard unmounts during sleep mode. The current value of the read ahead on the external sdcard is 512kb. This "read ahead" value can be changed using a free program called Kernel Adiutor.

Instructions:

Open side menu in Kernel Adiutor and select "I/O Scheduler"

Under External Storage, select 1024kb and select "Apply on boot".

If you are experiencing sdcard unmounts during sleep mode, please let us know if changing the default read ahead value of 512kb to 1024kb has any improvements.
[G Pad 8.3 Original Android Development] jesuita:
Installed the rom through the night and today faced a problem - no Wi-Fi at home at least as my AP showed out of range. Could see neighbours AP'S but not mine.

Now going to work set up the usual hotspot on my phone and could connect to it but none of the Google apps (Gmail, plus, YouTube, etc) connected to the Internet, all the others worked. (edit: this one is solved, the date changed back to 1961, corrected and can connect)

Flashed the rom directly from official cm12.1, installed the gapps I had on the tablet (2/3 months old) and flashed kitkat bootloader followed from a dalvik/cache wipe.

Any ideas?
[G Pad 8.3 Original Android Development] ThunderBolt_BR:
No issues at all here. Update went fine, no black screen or SDunmount. The smoothness is outstanding! Excellent job [MENTION=4517918]fefifofum[/MENTION]!

[G Pad 8.3 Original Android Development] Darkmasterhk:
I always used 1024kB with my old card and still got unmounts.

interestingly I got dismounts with 3 different sdcards, they all got the same brand (sandisk) and were labeled as "extreme xyz"

one older samsung card worked fine no matter what. now i got a new samsung card (evo) and again it works like a charm.

i also had cards of different size, or tried to change my filesystem/cluster size... only the brand/performance change helped.

i just found an older fujifilm sdcard, if i find the time i will test it, too.
[G Pad 8.3 Original Android Development] Deltadroid:
Thanks for the info. Instead of increasing the value to 1028kb, It would also be interesting to test if lowering the read ahead value to 128kb shows any improvements.
[G Pad 8.3 Original Android Development] jesuita:
After some testing noticed I had my router configured to use channel 13, after changing to 1 I can see the wi-fi signal.

Can anyone test if there is any problem with recognize wi-fi networks configured to channel 13?

CRDA support should be determined by your location services.

cm-13.0 released

I'm glad to announce the first public release of cm-13.0:

http://xdaforums.com/lg-g-pad-83/orig-development/v500-cyanogenmod-13-0-t3259135

Everything seems to work as expected, but cm-13.0 is still in development and not yet considered stable. There are some missing translations, and probably not all features are working perfectly, but I think it's decent enough to make a public release and switch to it. Those who want a stable rom should stay on cm-12.1 for a while longer, but I'm not sure if I will release more updates for it since I'm now focused on cm-13.0. BTW, you can update from cm-12.1 to cm-13.0 without wiping data, it will work, but from my experience you will have issues while editing tiles, so a factory reset is recommended. I will disable ota updates from cm-12.1 to cm-13.0 to avoid surprises, if you want to update you will have to do it manually.

There are three significant changes in cm-13.0:

- Tap to wake is now native (not a cmhw feature), so you need to enable it in display settings (it's not enabled by default).

- Bluetooth address is not read from misc partition anymore. There are some selinux (hard-to-fix) denials while using LG blobs for reading the real bluetooth address, so now we use the qcom way of setting the bluetooth address. That means the bluetooth address will not be the real one, and it will change with each factory reset. No big deal, most devices use qcom system for setting the bluetooth address anyway.

- Tethering and hotspot have been disabled, since this is a data less tablet. I made this change following Nexus 7 (2013) code (look here and here). If there was a case in which those were needed, I would consider adding them back.
[G Pad 8.3 Original Android Development] yugoport:

Our G Pad 8.3 :) On L my average screen time was around 5 hours... maybe 5 1/2. With M I'm projecting at least 7, many times more. The difference was practically immediate with [MENTION=4517918]fefifofum[/MENTION]'s initial M release.

I'm running these numbers based on an hour of screen time bringing it down to 80% almost religiously on L, where M has been at 86% or better depending on what apps I've been using.

I've also seen increased battery life on My N6 since upping to M, also with no difference in usage.

Strange thing here.

I've been using cm-12.1-20151006-UNOFFICIAL-awifi since two months ago.

I've never had any problem, my sdcard was always inserted and always mounted.

Since yesterday I start to get sd card dismount/mount loops constantly.

I did not change anything, no new software installed, no sd card remove, nothing written to the sd card!!

I tried rebooting, clearing cache, but my SD card is always mounting/dismounting...

I removed sd card and tested it on another tablet I have , reading, writing, sd card is ok, no problems, always mounted!!

how can this be possible?
