Introducing - LG Optimus Black

Hello everybody,
I've been watching the LG Optimus Black section for a while now and i wanna introduce myself on this forum, already know how to root, unbrick, install custom roms, flash cwm etc. but i'm not a developer so i can help you port or make roms or something like that.
Anyway, i wanna say thanks to the developers for their amazing work of making roms and i watch your progress
If i see the problem or know the answer i will try to help anyone but i don't know very much about development as i said before.
I know the answer of the question below but since i can't post in the developers section i will give my answer here:
http://forum.xda-developers.com/showpost.php?p=24777388&postcount=147
anyone knows how to make screenshots? I already tried menu+back, didn't work.
Can't capture my first "real" miui screens
Screen capture is included in this rom but doesn't work with me, i pressed volume button down and the menu key at the same time but can't find the screenshot anywere.
Hope this post isn't in conflict with the forum rules.

Try home button together with lock key
Or try volume down and home
Else download an app from playshop

Thank you, but problem is solved (for me at least )
For screenshots push menu+volume, they are saved to data/cache

There are different methods, some more simple, what version you have?
if you mean andriod version... I have 2.2.2
Look for UPK 3.6 and from there you can root with Blackjack.
After the root process you won`t lose anything but the warranty.
Okay, will do. Thanks heaps!
rooting your phone is dangerous but once you have done it, you will get a chance to try different roms. In short, Its fun!!!

Stripes on kernel 3.1 or ICS rom?

Hello All,
I tried to ask the question in some specific rom topics but i dont get answers so maybe i can try it this way.
I flashed SafariICSSamsung today again to check if the problem with the stripes is solved for my tab. It isnt and tried everything to solve it but im out of clues.
I've got an Galaxy tab GT-P7310
Tried the following roms today?
-CM9 unofficial
-SafariICSSamsung
- [ROM][ICS][OFFICIAL][14/09][P7310] StockRom Odexed|Rooted|Zipaligned|CWM Flashable!
Tried to flash it with:
-CWM 5.5.0.4
-CWM 6.0.0.8 (recommend)
The problem is when the display goes to sleep and i turn it on again the following error occurs.
http://www.youtube.com/embed/icHd14FX5ps
Everything is working in the background as you can "see". but its freaking useless this way. The only solution for me is to use HC roms and i really really hate them ICS roms on HC kernel also works but then the perfomance are a bit of a pitty.
Let me hear what you guys think and if there is a solution maybe!?!
Please ask a mod to move this back to General forum.
Then try the solution in this thread (esp post #2)
http://forum.xda-developers.com/showthread.php?t=1867124
(did you really use the forum search before posting? I've given this same response at least 3-4 times for different people posting the same question)
Im sorry. Yes i tried the search function but my english is not that good to search for "garbled screen". Im sorry. I will try the solutions mentioned over there.
This topic can be closed and sorry for the wrong post section!
EDIT: Anyway!! Thanks dude it worked like a charm! You made at least one person very happy today!!!

Rooting

First of all,hi guys.I am new to rooting.I just installed the official JB update for my S Advance and there are a few bugs which I understood could be solved using that No-Frills app.Could anyone post a link or just explain the safest and easiest way to root my phone so I can use that app?
Also,if anyone got those bugs fixed otherwise,please give me other advice,the problems are:
-720p videos tend to freeze my phone
-battery drains without no apparent reason sometimes
-games sometimes work like a charm but other times they barely work,freezing and so on
-random freezes of apps that shouldn't,like text messaging or simply pressing the home key
Sorry if other threads about this already exist.I honestly tried to find some answers to my question but a lot of things around this forum are completely new to me.
Also,besides the other things,a link or explanation on how to downgrade ro 2.3 back (just in case) would be great.
Thanks in advance!

[Q] Problem with SGA GT-S5830

Hi,
I don't know if this is the place to posting this but, anyway, i have to post it, if it's wrong please excuse me.
I have a SGA i'm root user and i've been flasing roms in my device for some time with CMW5. In this time I should made some mistake or smth...
I have an issue with the left touch-button on the screen, this button seems disabled... But when i was using StockLite v8 i discovered this button still works, this rom has the option to create a virtual button on state bar, when i touch this virtual botton it sounds two ticks, like it was executing both buttons, also this options table that appear when you tick in the button appears on its will. Anyway usb mass storage also don't work. This issue is fixed with terminal emulator tiping some lines. But left button's issue... I would appreciate any kind of help.
Thanks and sorry for my poor english.

Thanks for your help... but that's not working... This morning the button has been working for a while, and when i open whatsapp it's kind of disturbing 'cause it's doing what it wants while i'm using keyboard for tiping something.... I've tried tipping some codes in dialer for calibrate touchscreen but that's not working neither...

hello viper, I know that you know more then me in android, and your help is always appreciated, unfortunately instead of helping, prefer kidding me. If you have a better solution would be good that you give it to help this friend. Actually I said I didnt knew this rom.
Notice that "screen filter" has a function "enable soft-key backlightt" that could help. If dont nothing more than uninstall it.
At least I tried to help, and you?
I'm sure there is still time to help him, what do you choose to do?

this is purely a rom problem, some roms dont allow for touch keys to be activated, or in your case, only allow 1 to be activated. UMS isnt supported on every rom, but u can flash a thing for it, search xda for a UMS thing, there is one, and i have used it before

I'm glad what I said first was true, was a rom issue.:laugh:
btw, although it was a mistake, as viper said, the soft-key function of the app I spoke about, doesnt work in ACE [but the app is interesting (I didnt knew it) when you have the screen brightness to the street and enters a house, you can instantly download the brightness, and turn it back when you leave. I'm gonna try it better)

i dont know what you are talking about, if its the thing where when u enter dark areas the screen brightness goes down, and in bright areas, brightness goes up, then u need a light sensor on ur phone, which the ace does not have
You' re rigth ace hasnt light sensor.that's why this app seems OK, to do it manually

1. Install Terminal Emulator (google playstore)
2. Type this code in Ternimal;
Code:
su
echo 1 > /sys/class/leds/button-backlight/brightness
chmod 444 /sys/class/leds/button-backlight/brightness
If your touch buttons stay on, then your buttons work well xD
Great, Viber

[Q] Lost root after flashing Android 4.3

Hi guys, I know you have tons of rules here and I tried my best to respect all of then by searching for a thread containing info on what in looking for but I couldn't find one. I rooted my phone a couple of years back and have been flashing various ROMs since. About a week ago however I flashed an unofficial android 4.3 ROM by CyanogenMod and after that once I discovered how buggy it was (as per the developer's warning) I decided to flash something else. However I couldn't access my recovery menu no matter what I tried and it looks like I've list root but I can't be sure of that. Ask the root apps aren't working and I got a toast from one of them saying you need root access to use this. Right now what I want is a way to either reroot or maybe there's a simpler way of solving this problem. If I could access the recover mode menu I could use the conventional way of rooting but right now I can't even di that. I'd really appreciate a solution if any of you could take the time out to give me one. Thanks so much and I really hope to hear from you.
I assume you flashed Chas' rom. If you could just read the op.... Chas gave everyone a soultion on a silver plate..
er.sorry

To be really honest I'm not sure whether it was his ROM or not since I got it from a YouTube instructional video. There was a direct download link. Do you think you could please do me a favor and point me in the right direction to the solution? Losing my mind here since it's so buggy

Go to Chas' Asylum thread in Android development, and use the search option. He gave the solution on 8th of August.

At me it worked.
And saw it posted in a 4.3 thread/post
You have to disable and re enable it in developers option in settings.
And then try root privilege using apps to check if it worked like type su in terminal
