[Q] About rooting - LG Optimus Black

i was really confused about rooting my OB, i used my phone for about 4months and still with this stock rom V20b, and battery life sucks... will i need to format my phone and sd card before rooting? so many questions on my mind... and can someone give me steps for rooting? cause i been checking some links for rooting but it doesn't work, pushing thanks in advance...

when i had stock rom battery life was the same, but a lot of roms have this problem. you can to turn off some serwices which you dont need to use. also you can try other roms with root especially supprassed rom if you all time thinking about battery. http://forum.xda-developers.com/showthread.php?t=1487105
but if you have brand rom i think http://forum.xda-developers.com/showthread.php?t=1448803 smartflash will be good way for you.

I've read some threads saying that the battery performance it's better with Zeuz but. I'm using the 10A and the battery sucks too, I use the Juice Defender app to save bat.
In a few days I will upgrade to Zeuz to test it.

Of course in the zeus too you have turn off some services for long life of battery
wifi, 3g if you do not need them
But i keep 10a on pc for warranty

i had the same problem as you. the solution for me was to install a custom rom with governors. i installed zeus. the advantage of that is that with the right governor (f.e. ondemandx) the cp does not go to 100% so often and that conserves power. also a combination of custom i/o scheduler and governor saves a lot of juice!
so to sum up what i mean. install a custom rom that have custom governors. then download system tuner (free from market) and change that governor to something that saves power like ondemand/ondemandx interactive/interactivex slavazgen(or something like that). i recommend you to install the latest zeus rom because it has a lot of tweaks it is smooth and has zeus app that you can easily change the governor/io scheduler.
also a good thing to is via system tuner to freeze a lot of system apps that you don't use google what you can unistall/freeze
i don't know if it saves battery but it makes the rom goes faster
i also have read that disabling autosync (f.e. gmail) saves a lot of energy.
finally a trick that i also used on my previous phone and worked miracles on the battery is disabling 3g and use only 2g (if you don't use 3g everyday)

ok this is my opinion on your query....
1) rooting alone dosent do anything for your battery life, it only gives you "admin access" to your phone.
2) why rooting could be important/ helpful to improving battery life; on stock roms, there are default and "bloat apps" that you cannot uninstall or stop from running in the background, after rooting(admin access) you can delete/ freeze/ replace etc these "bloat apps" which will greatly reduce the amount of background processes hence saving you battery.
3) personal advice is unless you are confident about flashing and reverting back and forth roms and knowing what and how to get out of bootloops, etc is to get root, debloat your stock rom, create a nandroid and then take it from there...
4) you wont need to format your sd but its recommended to do a factory reset/wipe cache etc to your phone
5) about rooting v20b, i think nooby covered that in his "how to" thread over at the "General" section
hope this helps

[Q] How to update my phone's firmware?

Hi there guys. As you probably noticed,i'm new here,so pardon me if my question sounds noobish at the time,but I promise I'll learn from you guys! Thanks!
So,the question's simple. How do I update my phone's firmware? Don't wanna brick or possibly damage my phone here,as I just bought a couple of days ago. So,is there any risk to update the phone's firmware? Thanks bros!
Have you use search features before asking this question?
http://forum.xda-developers.com/showthread.php?t=1111771
Yeah,saw that already,but it seems to convoluted for me. I need a one-to-one kinda reply. Honestly,I didn't understand anything that was written on that page. So,could please someone clarify it in a more simple,noobish,way?
Thanks bro!
pdf guides are included in the kit. just follow them
either you can use KDZ or R&D for the official
or flash any custom ROM with CWM
(the tutor is already out there)
and the risk ? bootloop or brick maybe
Thanks bros! And another thing,what are custom ROMs? I keep hearing about it like Cyanogen? What's the upside for using it?

Custom roms in simple terms are unofficial versions of the o/s modified or "cooked" by people who want to add or remove certain features or performance tweaks. The upside is you can find a ROM that suits your usage and aesthetic preferences. For more info read through some ROM threads and compare their features.
However there is always a chance something could go wrong even if you know what you are doing. So my advice would be to read and re read the instructions from rooting to flashing radios to flashing roms and look up the termanology until you think you understand and then read it all again. There are some good guides around that can givevyou the basics.
Otherwise you can wait until your carrier releases a official update.

Thanks for clarifying bros!
And another thing,I just saw this vid at Youtube.
It's called "How To Install CyanogenMod 7 On Your Android Device"
I can't post the link here because im still new,haha!
Is it really that easy to install Cyanogenmod on your phone? But your phone have to be rooted first,right?
I saw the list with the firmware from various countries,but not mine,Malaysia. How do I solve this? I'm still suck with V10-a,which i think is the oldest firmware for OB.
Also,what are these baseband,kernel and build number thingies? Anything important? Thanks! Really starting to get interested in these things!
I think the following is related to malayians so you have to use an indonesian firmware :
http://csmg.lgmobile.com:9002/csmg/b2c/client/tool_mode_country_check.jsp?model=LGP970&country=MY
- you can flash firmwares anytime whatever the situation
- to flash a ROM (cyanogen, nova...) you need the custom recovery mod called ClockworkMod alias CWM (available on the market via ROM Manager app, or my kit)
- and for CWM, root access is needed
once phone is rooted and CWM installed, phone potential is extended to the infinite. you can then install a lot of useful apps of more and customize your phone.
I think the general goal of all of that, is to optimize and extend possibilities as far as possible and then you'll be able to say that you "truly own" your phone
Thanks for clearing that up bro. BTW,would you recommend me using Gingerbreak to root my phone? Since i'm using an older firmware,it should be ok,right?
no problem, blackjack should do it too. do as your feeling

Thanks bro! Anyway,anything else I should know and do before I root my phone? Like should I do a factory reset,battery level 100% or something?
2 steps : root, flash recovery.
know that you'll have to use an app to boot into recovery (ROM manager, anreboot, ezboot...) take a look at my thread for more infos

Ouh,wow,did that felt stupid,haha. So what you're saying is,after rooting my phone,I should get to installing ClockWorkMod Recovery,am I right? And the only way to install it is using the computer,connect it with the phone,and execute the UPK that you have provided in your download link. After that,I use the app,EzBoot,to boot into recovery mode,is this correct?
After that,what will I do in the recovery mode? Thankies again!
all right. as I said earlier, the recovery mode extends phone potential in an easy way. many ROMs and mods must be did via recovery. in fact, CWM helps you flashing files, roms, doing backups/restorations and more. jump the step and see by yourself.
don't forget to backup before anything

By backing up,you mean backing up contacts and internal memory stuffs,right?
All right! Will root my phone as soon as my charge hits 100%! Using gingerbreak! Is the root reverse-able? I mean,can I unroot my phone once I root it?
you don't need 100% battery as long phone is plugged. for now, blackjack doesn't have a reverse process. but gingerbreak, yes, considering the fact you stay on v10a/b. you may try with the new superoneclick. the most radical method is still flashing a firmware (so you'll lose all stuffs)
and yes, backup any saveable thing. although CWM saves all datas, more safety is more safe

[Q] I can only send a text message to 10 people max at one, why?

Hi, when i try to send a text to multiple people with one text message, I'm only allowed to send to 10 people max, is there a way to get rid of this?
Cheers.

http://forum.xda-developers.com/showthread.php?t=1371755
I believe this could be a limitation of the ROM or the service you are using. Search the developer forum for a ROM that gets past this limit and check with your phone service provider (I read somewhere that Verizon has this limit, but can't vouch for that as I am in different country)
thanks, but I am new to this whole android world, this is my first android coming from a nokia n900.
I have been reading, but it seems I need to root my phone which is now difficult because as soon as I received the phone i updated it and now have the kernel LA6 instead of original LA4 which is more difficult to root.
As for the thread you provided matius44, does the .apk file only work with ics roms or can one install it with just a rooted GB rom.
----
Just so I can be sure, I do want to root, but I'm slightly confused, is it correct in saying that I need to downgrade the fw and kernel to an older stock rootable rom then root the phone? or is this wrong?
Yes- have a look at the developer forum - there are details here...

That used to be the case, but there is now an easier way which flashing pre rooted ROMs directly and you're good to go, here is the thread:

As for the .apk mod, I never tried myself honestly but there are versions for GB and for ICS, any .apk with ZCLP in it's name is for ICS you don't need that, take the other ones
I've tried dr. ketan's way and it didnt work for me, maybe i didnt know what I was doing,
Ill try these pre rooted roms, I just basically flash them to the phone, does all my data in my phone get wiped off clean? if so, what do i use to make a backup.
btw sorry for all these questions.
and thanks in advance.
It's been that long since I rooted my phone I've forgotten how to do a backup without rooting! Titanium backup needs root.
Have you tried booting into recovery mode then doing a backup from the menu that appears (vol up+home then press power until Galaxy Note boot screen appears then let go of all buttons) I'm pretty sure you can backup from there.

You can have it either ways, wiped clean or not, up to you..
At the pre rooted ROMs thread there is a screen shot showing the three file you will find in the zips and the places they should be put at in Odin, if you do NOT want to wipe your data do NOT choose the CSC file, only flash PDA and phone (modem)
Or you can use Titanium Backup to backup your user apps only, do NOT backup system apps but your settings will be lost of course
Your preference
EDIT: Sorry forgot you don't have root lol! Sorry have no idea how to backup without root, try the poster above me suggested
Congrats Matius! 1000 posts! That is great work!
no you can't backup using that method, it just give me options to reboot, wipe everything off and some other things. all i need to backup is mainly my contacts and some data, ill try kies.
Kies should work. I wish I could remember what I did to create the backup - I've done a quick google and only found using adb and a terminal prompt, which I have never used. A quick search of Google Play shows some that may be worth a try and are free.
Wish I could be more help but for the life of me can't remember what I did that first night with my Note and got it to backup.
Good luck with Kies and enjoy flashing ROMs!
even kies doesnt work. i think astro backup will backup my files, as for settings ill just have to deal with it.
OK - good luck!
BTW - If you get heat issues after flashing - don't panic! Leave the phone off for five to ten minutes to cool down then charge it for an hour with the screen off. I found this was my biggest worry when I started flashing. Got really hot - thought the screen would melt. Now I just use the above process and never have problem.
All the best!

To make sure you are rooted use a file explorer app (root explorer or ES file explorer)and try to copy a file (pic, video or anything) to /system folder
If it's saved then congrats you're rooted

[Q] Help..Missing option in CWM recovery

i have cwm recovery 6.0.3.0 by Davidmarco installed on my xperia T... i want to wipe battery stats so i reboot to recovery and there is no option for that...
i also check in Advanced menu and all other menu's by there is no such option... so how to do that?? is there any fault with my recover...
i am on stock jb rom stock kernel.....
I don't have it either so its not a fault with your recovery
Iv known devs to remove it from their kernels as its "a useless feature"
Altho I liked to wipe the battery stats after a new rom and full charge whether it was useless or not

is deleting batterystats.bin file really help calibrating battery? have u tried ever?
No, wiping batterystats has nothing to do with calibrating battery. In fact, wiping batterystats.bin had almost no use except resetting the information in Settings - Power management - Battery, that's why it's removed from CWM I think.

Sorry never tried it, I am curious tho
Have you replaced your battery?
What is it your trying to achieve?
is this any use to you? (iv never tried it)
https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=en_GB
Description
Requirements: Android 2.1+ | Root permissions
Calibration needs to be done after flashing a new ROM, but you can calibrate any time you think your battery is miscalibrated. This program does it by removing the batterystats.bin system file. The OS generates a new clean batterystats file soon, thus any fake information from the previous ROM is removed.
It's suggested, but not necessary, to let the phone fully discharge after calibration, then charged to 100% without break.
The app shows your actual battery status, and only allows you to start the calibration (i.e. removes the file) when it's fully charged, unless you force earlier calibration.
The voltage meter can be useful too. Full charge is around 4200mV.
There is an option to beep when 100% is reached so you don't have to closley follow the changes.

My Phone freeze and reboot after swapping (RAMEXPANDER, Swapper2, etc.)

hi,
its my first thread in XDA. before we go any further i am using Xperia SP with Cyanogenmod 12.1 ROM (latest NIGHTLY),
use the original kernel from the ROM, not using xposed framework.
while using it as everyday use, i think the performance about this ROM is kinda weak, so i think im gonna use swapping for better performance.
after done make swap Partition and 2nd Partition, ive decided to use Roehsoft RAMEXPANDER (Check on PlayStore). it is indeed easy to use, choose the swap partition, click optimal value, and click swap active. the first 5 minute it was working flawlessly, after ive turn on and off airplane mode, it start freezing for like 10 seconds, and it start crashed and rebooted, excatly everytime i turn on swap from another app.
should i use a different ROM, or theres a fix for this?
i hope someone would like to help me, i know i'm a noob
sorry fo bad english

Battery Life = RIP After Marshmallow Update. Any Fixes/ways around it?

Since I upgraded to Marshmallow my battery life on my T Mobile LG G4 H811 has gone horribly wrong. My phone loses battery at least 20% faster than on lollipop. I am using a debloated custom Rpm since stock marshmallow was worse. Is there any fixes for the bad battery life? Any tips you guys can give me or kernel I can flash that will improve battery life? Anyone else dealing with bad battery life compared to lollipop?
Which ROM are you using? Debloated marshmallow should get you at least the same battery life as LP in my experience. Something is not right with your setup. Did you restore anything? Dirty flash?
Try clearing your cache and dalvik.
i am on genisys rom and it sips battery.
Use a file manager and go into system/bin and look for logd and rename it to lgd.bak then reboot. Battery life should be a tad better
Prolly not your problem but just to share in case:
Had the same problem, horrible battery life after upgrading to MM. No info on the system battery stats. Turned out it was the media scanner tripping out over this old QuickTime movie file I have saved. Better Battery Stats was the only thing that showed it, so if you haven't already try that to see if it can tell you what's up.
(Really curious why I had no problems with that file on LL, but guess that's another question).

I am on MicroMod777's "G4 H811 20i xTreme ROM" It already comes debloated. So I am not sure what is causing it. I did a clean install when I installed the rom. I will try clearing cache and dalvik.

Nice I will need to try that. System battery stats are complete BS. I usually use my phone with the screen below 15 percent and my phone says that's what consumes the most battery which is obviously false.

Like you I felt LL to be easier on the battery than MM, but not too much. It shouldn't be 20% worse. Cant go back to LL because of stage fright. You may want to consider CM 13. That's about as debloated as it gets and even CM can be made barebones. Any of the kernels with interactive governor should help with battery life. Good luck.
