stock gb

So my mom has stock gb non rooted but her android is uses 80%of the battery anyone know what's wrong?

Stock ROM is the problem If I was you.. id root her device and install calkukins GB ROM as it looks stock but has many great tweaks and much better than an awful stock ROM... of course with her permission. You can always also update her phone to the latest android 4.0.4 ICS update.

Need help with ROM

Hello everyone,
My wife has Samsung Galaxy Ace 2 and after JB 4.1.2 update the phone is very slow. It lags like hell so asking help from you guys. She does not need any fancy ROM loaded with ton of customization options, just simple, fast rom. Doesn't matter if it is JB or GB.
GPS and 3G/WIFI should work well, because shes using it for navigation sometimes The BEST would be tweaked and fast 4.1.2 JB stock rom if this is possible Or nevermind, every peace faster than this would be great.
Please suggest me something. What rom should i choose? Phone is:
Mode: GT-I8160
Android version: 4,1,2
Baseband: I8160XXMF1
Kernel: 3,0,31-1106830 #2
Build number: JZO54K.I8160XXMF1
THANK YOU!!

For the lagg and force closing, go to applications > active processes and see how much ram it reads. If that says 482, then u need to apply this http://forum.xda-developers.com/showthread.php?t=2389395 trick. chances are all will be smooth after that.
If u fancy the extra's, you should go with Kyrillosv8.
or you can flash MG2 via odin, I find that a tad more stable than MF1 (again apply the patch linked to above if u end up with 482 MB RAM then.)
Lastly, flashing D-kernel will speed things up and increase stability as well.

Okey now, i did the first thing, flashed V1 624 memory file via ODIN, everything went great, phone seems a bit faster. Now i am trying to flash D-kernel via stock recovery, but it says this: E:signature verification failed. Phone is not rooted. What can i do? Thanks.
And another question, i saw supercharger is made for this phone. It is worth flashing it for SPEED?

First flash this from the stock recovery http://forum.xda-developers.com/showthread.php?t=2141395
then flash D-kernel from that CWM recovery.

Thank you for this helpful thread. I was looking exactly for the same fix to my phone. I could apply both the RAM fix and the Kyrillos mod successfully but unfortunately I ran into a bootloop after I have applied the D-Kernel patch. Since I am not experienced, I am wondering if:
a) I did something wrong
b) Kyrillos already patched the D-Kernel
c) if my D-Kernel patch was not compatible (buggy file or not compatible with Kyrillos)
Now I have flashed back XMF1 since I did not know how to fix my bootloop. How can I successfully apply D-Kernel to achieve the desired performance?
Regards,
Quentin

@Hummer951 solved this issue with the right patch: http://forum.xda-developers.com/showpost.php?p=46456493&postcount=2
However, the performance is still not really convincing. Would you recommend to apply further tweaks like liquid speed or PurePerformances™X?

[Q] Rooting/Custom ROM installation help and advice....

Hey guys,
It's my first question on this website so please forgive me if I am too noob-ish with my questions.
So recently I got an OTA update for my Sprint Samsung Galaxy S3 asking me to update from jelly bean 4.1.2 to 4.3 and I did so with no second thought. However, within two weeks of using the new jelly bean version, I am sick of its performance issues, battery life, wifi problems and a host of other annoying things it brought to the table. So I went about looking for advice on several forms on how to improve performance and make my phone usable again.
In the end, I ended up rooting my phone successfully using a thread I found.
I also installed a custom recovery (CWM) so I could flash well-rated custom ROMs. Now, I have a few questions before proceeding since I came across a couple concerns other people expressed on other similar threads......I heard the new 4.3 update came with some kind of new bootloader and Samsung KNOX, and I've read that it could cause problems if I try to downgrade my phone back to the stock ROM (4.1.1) or 4.1.2.
So I have ruled out the option of downgrading my phone given the risk of permanently bricking it.
So my question and concern is.....can I go ahead and flash a custom ROM at this point without bricking my phone? I am thinking about Cyanogenmod 10.2, which is apparently based on jelly bean 4.3. Can I install cyanogenmod 11 (based on 4.4 kitkat) instead of 10.2? What are my risks of flashing a custom ROM through CWM at this point?
Please help, I'm stuck!!! Any help is much appreciated

Cyanogenmod is a good rom that improves your performance alot since bloatware is removed. My S4 on a stock rom uses on average 1.14gb of ram. When I switched to Cyanogenmod 11(4.4.2) It knocked it down to 550mb avarage. I have noticed a significant improvement over the stock rom. If you do it be VERY careful and follow all instructions exact. Make sure everything you download is for your model and you should be fine. Other than that, like you said downgrading is out of the picture so you can try other roms that are 4.3 and up if you don't like CM10/11.

yeah i also would also recommend Cyanogemod, for battery issues i would get the app Performance control and look up which Governor and i/o schedulers, i personally recommend the ondemand or ondemandx governor, you can check DIS out if you want to see it explained, just a brief explanation of why you should use them ondemandx clocks itself to 500mhz when the screen is off and is pretty much a nice battery saver, as for i/o's i myself have not done very much research into these but there are some threads on it too, i just use deadline.

[Q] Best-ish Sony Stock ICS

Hi,
I`m planing to downgrade to an official Sony Stock ICS ROM (& and strip the bloatware) to get all the features working (HDMI). I was planing to pair the stock sony ICS with a kernel like Lupus. Before doing this however I wanted to ask if anyone has a recomendation on which Stock ICS version to get because I remember reading that one of those was a major flaw.
Additionally I'd like to know if anyone has/did run stock ICS+custom kernel and could share his experience with speed/smoothness and such, because I remember running the LT18i_4.1.B.0.587 firmware before rooting my device some years ago and the whole system was so laggy ... which lead me to try custom ROMs first and evetually unlock the bootloeader and go for custom Kernels later.
Any other recomendations are welcome.

I believe the newest is the best you can get, which is 4.1.B.0.587. You can also try 4.1.B.1.13, but it is a branded firmware and may have some additional bloatware installed in it.

Thanks. I remember 4.1.B.0.587 was really laggy when running on stock "everything". I'll try it and see if I can get it running smoothly with a custom kernel...

Even with a custom kernel, stock 4.1.B.0.587 will still lag a lot because of all the bloatware Sony added inside.

And extremely awful optimization.

You guys are really making me think twice about this.

That's just life. Sony gave us really crappy ICS firmware.

[Q] Bootloader question :)

I recently updated my N7105 to the recent 4.4.2 Nordic ROM ( n7105xxufnd3 )that was floating round that tripped my Knox, which I dont care about.
When i got sick of the updates abysmal battery life i flashed the latest stable release of CM for the GNII LTE a 4.3 based ROM with out issues.
But I'd like to know if i can revert back to my original ROM i.e. WanamLite MC3 V1.3, a TW 4.1.2 based ROM, for its spen support, battery life, atpx and boeffla sound support (im a big music listener) w/ Wanam's Adam Kernel.
Can i do this with out running into any issues, despite the gap between a 4.4.2 boot-loader (as I've been told i cant roll-back from this version) to a TW 4.1.2 ROM?
Thanks in advance guys

Based from what I remember, devs say that when you are with KK BL (ND3), you cannot flash a stock rom lower than it and the lowest custom rom that you can flash is 4.3.

Is there anyway i can flash an older bootloader? and/or is there a similar ROM to Wanam's that uses 4.3 as its base?
As awesome as CM is, there are touchwiz features specific to the note series that are hard to implement on CM/ASOP based ROMS :/

Do not try to install anything lower as it will break device. I'm sorry, I know nothing about wanam lite.

I have a unrooted note 2, manually installed 4.4.2 as 4.3 had major battery issues.
Things got worse for me in 4.4.2 nordic countries and I went and downloaded the offical roms from sammobile and am now back on 4.1.1 offical.
It can be done.

Wow, I thought once you are in a higher bootloader, you cannot install a lower one. No problems at all?
I'm sorry if I gave out wrong info, that was how I knew it was.

I have no issues at all.
Apart from missing out on features from 4.1.2 and above everything works as if I didnt update the device at all.
I would not do a restore from higher up android versions but if you start feom scratch its all good.
And I can say my zero lemon battery is working at it should be, I now have days worth of battery life.

I'm getting invalid kernel/ ramdisk size error on bootloader screen. This is the first time I got this error while entering recovery screen. I'm don't know much about this. Please help.

Sorry champ but this threqd is for a galaxy note 2 specifically a gt7105 and has installed a samsung stock rom, I have done this and have gone back to 4.1.1 but seeing as you have a rooted romed moto x it is out of my league.
I dare say this process is incompatible with the moto x and seeing as you can get into recovery or cwm or what ever its called you can still flash a rom with the relavent bootloader that was previous to your dilemma
