Hi,

I'm about to buy a LG G Pad 8.3 and plan to root it and flash CM11 right away. I've read in a few places that there is a brightness issue with custom ROM's but haven't seen a clear way to avoid it or fix it (other than perhaps flashing stock reflashing CM?). I've also seen various posts suggesting fixes to this in the latest CM builds and also a custom kernel that could be used (AIC?). So which, CM build should I use (official, infected) and can anyone please explain how to avoid the low brightness issue?

Thankyou!

Use whatever CM build you want. I don't know much about the other fix, I assume you mean when infected said he committed some change that is ROM side.

The other method is to pick whatever CM version you want(or other ROM for that matter). Use the AIC kernel installer and select custom ROM's when prompted. Then if you were on Stock LG 4.4.2 before you flashed CM you pick the 4.4.2 ROM, and if you were on Stock LG 4.2.2 before you flashed you pick the 4.2.2 ROM. 4.4.2 and 4.2.2 have nothing to do with CM version only which Stock LG ROM you started with.

I think you are referring to a dimness issue when going to a custom rom from stock 4.4.2. Its related to the custom recovery not supporting soem changes to the partition or directory structure made by the LG update. Just make sure to update TWRP to 2.7.0.1 before flashing your custom rom.

Any rom will due. I'd advise sticking with the M-releases so you can get some stability and be able to do a monthly dirty flash. I've heard good things about infected's CM build.

Ok I'll risk this question (I thought that I knew the answer)....

Brightness

I was on Stock 4.4.2. I had rooted the Pad and then ensured that the version of TWRP installed is 4.4.2-v500-TWRP_2.7.0.1-recovery.zip.

So I should be fine when installing Infected's build of the Slimkat ROM as it also is built on 4.4.2 and yet I can't see a thing when it first boots.

The screen is way too dim. Eventually when I work blind to get it to finish its set up the screen is still very dim. Booting back into recovery it is fine and bright. A reboot and it is really nice and bright for about ten seconds and then it will reduce a small amount but placing into standby and then back on again and it is perfect.
It will remain perfect until I need to reboot it and then it will dim slightly until I place it into standby and then back on again and then it is absolutely perfect.

So what am I missing with the version of TWRP I have installed over that of the stock 4.4.2 UK OTA ROM and using any custom ROM based on 4.4.2...?

Thanks

From what I can understand, TWRP 2.7.0.1 should have fixed that startup dimness issue (reference: http://forum.xda-developers.com/show...&postcount=343).

Otherwise, you can try flashing back to 4.2 stock rom before flashing to a custom rom (reference: http://forum.xda-developers.com/show...&postcount=360).

I understood that as well but now get the impression that other influences could be a contributory cause. In the thread of Infected's SlimKat's ROM he had noted some build issues which could well have caused that, as others had noted it, and so compiled another build. One other who had noted it had flashed back to 4.2 and used 2.7.0.0 of TWRP and yet still got the issue.

I was fighting a dimness issue on the latest Mahdi last weekend and went back to stock rooted because of it. Something definitely has changed since I took the 4.4.2 stock update from LG. I did not try going all the way back to 4.2 as an alternative. I do know that the issue is worked around in the TWRP with 2.7.0.1, however once I boot into Mahdi everything is very dim until I change the brightness slider.

In addition when I would change the brightness slider (in mahdi) the rate at which the screen would change was dramatically different from previously. Something in the 4.4.2 update has changed the way brightness works on the V500. I'm wondering if it is related to the fix that made the 7 led lights go away for so many (including me) on 4.4.2. I can say that it was annoying enough for me to revert to stock and simply run stock and rooted again...
