[Q] About rooting

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

Yes, that´s correct. Or you can do it directly in CWM. Sorry for the bad english.

[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.

Battery Stuck at 100%

So after 8 hours my battery still said 100% and even shut off due to dead battery and it still said 100% full. In TWRP it also shows 100% full. Any ideas? I have it on the turbo charger now, since it died, and will wait about 2 hours then try to reset battery stats. Not sure what else to try. Nothing new installed, phone is stock other than rooted and TRWP.

This is why I stopped rooting phones. One feature breaks 2-3 things and end up flashing daily update zips.

huh?
The phone was rooted the day I got it, Nov 9th, and it just started doing it today. So how does root automatically cause the issue?
Anyway, any ideas would be great I think resetting the batterystats has worked just curious what may have started it.

I've never had issues from just rooting. Rooting a phone doesn't cause issues but rather installing root apps and changing things causes issues. I would try to flash back to stock (backup data first) and then root it again to see of that fixes it.
Also did you use CF-Autoroot or one of the tool kits?

I fixed the issue, after that battery died I let it charge for about 4 hours with the quick charger and then reset the battery stats by using an app that deletes the batterystats.bin file. Then did a reboot and now the battery level is no longer stuck on 100%.

Same happened to me, phone is on for over 20hrs and battery is still 100%.
Waiting for it to shut off.

You can also try the bootloader trick, though not sure if it will work here.
Boot to bootloader, change to logs menu. Hold power until reboot.
FYI, batterystats is not related to what % battery shows is left.

root has nothing to do with breaking your phone. all root does is give you superuser permission. what breaks phones are dirty hacks that you yourself chose to use.

But that's strange, since it reported 100% in TWRP as well, looks more like firmware problem no?

Yeah maybe battery firmware confusion. I don't know where TWRP gets its reading from.

A ROM question

Not gonna ask the best ROM, as everyone gets a bit uptight about those, and feel the need to defend "their team" and all that...
My question is more generic, in that I am wondering if there is even a ROM out there that will meet MY needs... so if I list those things that I would need in a ROM, maybe someone can simply answer yes or no and point me in the right direction?
Here is what I would be looking for in a ROM:
1) Stability, has to be as stable as stock, no screens of dead or random reboots
2) Speed, zero lag, fast and fluid
3) Everything has to work. If it works on stock, be it apps like VZW Visual VM or whatever, it needs to work on the ROM
4) More polish and eye candy, nice animations, make the device beautiful to use without being buggy or laggy
5) Battery life at least as good as stock
If there is a ROM that gives you all that, has a bit more customization but not so much that it takes half a day to set it up, what would it be? Or would I be better served just using a different launcher?
I have not installed a ROM in a couple years... I was a flashaholic for awhile, but a few phones that I had in a row worked really well in stock form, and some had locked bootloaders that never got cracked, so I kinda gave up on them for while and so my knowledge is a bit rusty...
What I don't want to do is go to the trouble of installing a new ROM and having it not work, or be buggy, etc... This has to be daily driver quality and I want to USE it, no spend too much time fiddling with it.
Ideas?

Cool. And I am sorry if this is a dumb question, but like I said, it has been a couple years since I installed a ROM...
I can use Wug's Nexus toolkit to install a custom recovery, and then take the downloaded ROM and recommended GAPPS files, go into Recovery, install ROM, install Gapps, then factory reset and I am good to go?

I don't personally recommend toolkits unless you have ADB/fastboot knowledge and experience but otherwise yes. You don't need to factory reset after ROM installation, just do the required wipes, generally listed in the OP of the ROM you choose, in TWRP, prior to flashing.

Got it, just installed it. Put the ROM and Gapps in a folder and I will first make a Nandroid of my current setup... Then I will try it out.
The OP for that ROM doesn't have any instructions, but you said that in TWRP that I need to wipe cache and stuff PRIOR to installing the ROM? I always thought you did that last? Am I remembering it wrong or did something change?

For your first installation, wipe, used advanced wipe, then select dalvik, cache, data, and system. Then flash your ROM. Updates to the same ROM can usually be "dirty flashed" by simply wiping cache and dalvik prior to installation.

Tried it out, but found that it was slower in Antutu by 3,000 points and it was a bit laggy at times... Weird.

I wouldn't hold a ton of value or base anything off Antutu.
Sorry if I didn't pay attention to time stamps between your posting. I did look at your stats and see you have plenty of experience here. May just need to give a bit of time for ROM to settle.
I have tried several ROMs here and consider there to be a BIG 3, or the most popular. I won't say the names due to the fact that I don't want to place any one above the other. However, I would recommend a ROM with Layers.
When you go to wipe prior, wipe all but internal storage. I wipe twice, just because I am OCD. Flash all necessaries and sometimes an alternate kernal will help, but give baked in kernal a chance. At least a cylcle or two. Wipe the Davlik and Cache after flash, as TWRP suggests.
There are a few to choose from which are close to stock without overdoing it. Most things folks want to do to customize can be done with apps in Play Store without over loading file size of ROM.
OK, I'll say it, but I don't want you to think I am partial. Try Chroma

Oh trust me, I have no concerns with people being partial. Some people get bent out of shape in "best ROM" debates, but I don't. I WANT to know which ones are top tier, and why, from people that have used them.
I know that Antutu is not the end all be all... But when I saw it was laggy, I run that to see if it is just placebo, and sure enough, it was slower and there was a little stuttering and lower frame rates in the final 3D game test... I just use it as a reference point, that's all...
I played with Layers a little and didn't really get much out of it... It just seemed to change the color a bit on menus and things, so I didn't see a lot of benefit.... or am I missing something?
I will take a look at Chroma and see how that looks, thanks.

Battery better on 3.5.4 than 7.0

So everyone says they are having killer battery life on nougat, and while it isn't horrible for me, I feel I had better battery life on stock 3.5.4 plus Blu kernel.
Am I the only one or does anyone else notice this too?

Well, I have better battery life in 3.5.3, thats why i downgrade it from 3.5.4

I didn't have great battery life right off the start. What I ended up doing is a wipe of caches and then a factory reset and since then I've had AMAZING battery life. On my phone I have a feeling that something didn't finish in the cleanup.

Reflashed 5.3.4 and update to 4.0.
It's the phone, its killing my battery

Same. Think I'm going to have to wipe completely--hate setting up everything again.

How did you go about doing that? Did you start on 4.0 and go backwards to 3.5.4?

Yup, I did that last night. On 3.5.4 no root, but using Blu Spark kernel. Will give it 2 days to see if the phone calls still drain as much battery as they do. If so, then I'm completely lost lol and will update to 7.0
