Noob questions about custom roms and rooting. - Nexus S Q&A, Help & Troubleshooting

I am getting lag in temple run and I would really like to make it smoother. I am running unrooted stock 4.0.4.
I can sacrifice battery life for better performance.
Will it be possible for me to backup all my data before? How do I root without loosing data?
So then which Rom gives a serious boost in gaming performance? And will I need to put some kernel as well? Sorry this is my first time doing this sort of stuff so be patient with me.
Or is there a way to over clock just using the stock Rom rooted? And does that help much with performance?

Hi!
If you already rooted your phone and you have the custom recovery you can make a complete backup of your rom from there (this is for safety),then if you want to change rom you can make a backup of your apps and contacts with titanium backup or similar apps.
You can also try to flash only a custom kernel from the recovery (first wipe the cache and the dalvik, not the data so you wont lost all your things ), i suggest matrix or air kernel, and then play a little overclock with nstools (it's free and can handle all the mods in the nexus s kernels). Don't use extreme settings such 1,4 ghz 'cause you can seriously damage your phone, try to enable the 1,2 ghz step OR rise a bit the liveoc to 110% so you can have 1100 mhz.
The last thing to try is to install the chainfire3d app, it installs opengl drivers tha can give you a performance boost

Thanks but I am not rooted. I have made a thread in the general section about it, would you happen to know how to root stock 4.0.4 without losing data?
And can overclocking really damage something? I know overclocking on PC pretty well and I know there is no such thing as damage when it comes to PC overclocking. I figured smartphone overclocking would be more risky.

Well as far as I know you'll lose your data in the rooting process, while regarding the overclock is always "risky", especially when you start to raise the voltages to achieve stability at higher freq

You can use "My backup pro App" and make a backup of all Apps and Data.
Copy files on your PC and after root operation, reinstall "My backup pro App" and restore apps and data.

So it will backup my saved game data as well without rooting?? Game data is really the only thing I care about not losing.

New G2X Checklist

Anyone able to give me some helpful todo's for my new G2X before I do anything with it? Some of these will not be G2X specific obviously. Anything that doesn't involve rooting would be nice. I'll root later on.
I've been told to let the battery die all the way down before charging it at all. Is there any truth in that?
Should I install any sort of battery metering software, or anything else of that sort?
I don't think it's necessary to initially drain the battery all the way down. For the first 5 charges, I fill it all the way up and drain it all the way down to calibrate the reading, despite the faulty LGE battery drivers. I also try to do this with the phone off.
After that I charge it normally whenever I need to.
I personally don't care for any battery-related apps, but I know a lot of people do.
you don't ever need to drain the battery all the way to calibrate it. just root and download BatteryCalibration from the market. it deletes the battery stats and thus insures the phone is reads the battery level accurately. the same can be done in clockworkrecovery
What other things would you guys be doing to prep a new phone?
Do you use any particular tools to do a full stock backup, etc? Pretend you are just cracking the box open and what to start off right.
when I get a new phone I...
-root
-flash clockworkrecoverymod from the dev section
-create a backup in clockwork
-delete battery stats in clockwork (assuming u charges to 100% first)
-install titanium backup pro
-freeze or delete any unwanted apps and services
-restore apps from previous phone (but never any system apps)
-use rom manager to fix permissions
-boot into clockwork again and make another backup
-use any file manager or rom manager to rename your backups however you see fit. I name the first one "factory backup" and the other "stock completely setup"
- use phone
well first thing i would do is put clock work mod on it using nvflash ( the newer version of cwm) then after thats on i would boot into that scroll down to backup and restore and backup my stock rom, now i have a backup of my stock rom, dont use rom manager that would be fake flashing it another words if u get into a sticky situation and are bootlooping u cant do **** about it, thats why u flash cwm with nvflash that way incase that happens u can hold power down and vol down and get into recovery......ok after installing recovery and making my stock backup i then would use super one click and root it and put pauls fix on it (paul obriens) hot fix, makes the phone faster and is stable, lg ****ed up somehow with boot up and he fixed it....ok so after that i would make one more backup of my rooted stock rom, now u have a backup of a pure stock rom and a backup of a rooted stock rom, now this way incase u needed to take the phone back to tmobile u would restore ur pure stock rom and all u would have to do was run nvflash and flash stock recovery and ur good. now the reason for the rooted stock backup is if u just wanna go back to stock for whatever reason, u wouldnt have to root it, it would already be rooted......that being said u have ur backups u have recovery and rooted now i would go explore with some roms and see which one is for u then when u find one u like stick with that then flash a custom kernel and so on and so on....sorry for the long post
and yes before u make any backups install titanium backup and backup all the apps u want this way if u install a new rom u can restore ur apps that u want on that new rom
Awesome post.

You will also want to replace your launcher. LP or adw ex.

Well you should be at full charge when you wipe the stats... or how else will the phone know that the battery is at 60% = 60% not 60% = 40%. Start at 100%, wipe stats, then do a full drain until the dies. This will write stats of the true length of the battery.
I don't really think wiping the battery stats is even required but I would give it a few good full charge/drain cycles to tell the phone the full length of the battery; this is important for any device.
When I first got my phone, download root app+drivers, root, NVFlash ClockworkMod Recovery, BACKUP, full charge + battery wipe, cache wipe, flash, enjoy.
Or just enjoy Stock for a while. It is a new device and Stock works pretty well (at least it did for me). I like staying stock on a new device for a while so I know what to expect out of custom roms.
So I only have the internal memory at this point. Once I use CWM to perform the backup, should I grab the backup file(s) off of my device and archive them on my computer just in case something goes awry?
well of course you need to charge to 100% first. the whole reason the app and option in clockwork exists is because draining lithium ion batteries is unhealthy for battery. if you charge to100% and delete the stats it will read the battery correctly. I'm not saying a drain doesn't achieve the same result but as I said it is unhealthy for the battery.

Put on diet using System App remover or Titanium backup to freeze

flash Faux123 Stock Kernel .03 using Kernel Manager Pro
pimpmy cpu to OC to 1.4ghz
VM heapsize app to change heapsize to 48 (helps with graphics)
SD speed increase app (allows SD to read/write faster)

Oom allocating task: Enabled
Run Titanium Backup and clear out Dalvik files.
Use ADW EX and put on fast settings
Use spare parts app to turn off all transition or windows animation.
Note: Anim mod app can add different menu animations. I use this only because it gives a cool flip animation to the top task bar. Even if all animations are turned off.
I'm sure there are other ways about this but this is the easiest way to do things with apps instead of trying to use a terminal and etc.
Recommendation: Root tools has some good stuff but do not run fix permissions cuz it could lead to breaking your root. This kept happening to me when i used superone click and did that lol

Few questions after root=)

Nandroid:
i am new in using nandroid backup and i have few questions about it.
1st, what is the "boot" it backup? isit the rom or what? if i restore nandroid after flashing a new rom, will the old rom comes back again?
2nd, does it even backup the theme? if i factory reset because of installed a wrong theme, if i restore my nandroid, will the wrong theme comes back again?
3rd, how about the system errors? will it also backup them?
Overclock in tiamat rom 2.2:
Whats the different in overclocking with the settings inside tiamat and with setcpu? Normally i use setcpu but i found it drain more battery .. if i overclock with the tiamat settings, will the setting included when the screen is off? bcause normally i set low frequency during screen off with setcpu to save some juice
Lastly, can someone explaine the option "disabling logcat" to me? Any benefits or risk if diaable that?
sry for my noob english.. thx to anyone who answer me =)
Nandroid, which is what is most commonly referred to, is the process of backing up the current system and data which involved with said system (which includes your system, recovery, boot, data, etc.). That said, restoring a full backup in like re-installing your old ROM with all the apps and what not you originally had installed at the time of the backup including any user data.
What does this mean? Lets say you're going to install a new ROM, you make a backup of your current ROM, then you did your wipe (factory reset) and installed the new ROM. You find yourself having issues with the new ROM, you can simply restore the backup and it'll revert you back to your old ROM with your old information in tact.
Now, say, there's an issue in the said ROM and you make a backup of said ROM the flash a new ROM or something and you decide to revert back by restoring it, then yes, the error will come back.
In terms of the overclocking, the kernel needs to first support being able to overclocked first. That's where the Tiamat ROM/Kernel comes in since it supports it. SetCPU looks at what the kernel can support and let you set it that way, what the Tiamat creators did is allowed you direct access to overclock it if you wish without the need of using another app but you are free to do so (just don't touch any of the overclock settings in the Tiamat's settings).
And logcat is a log file that pretty much shows the activity of your device and useful for debugging issues. You can safely turn it off is you please like it.
In simple terms nandroid backup is like backup of windows where system image is created and restore the system to state where it was when backup was created.
it will put your system in same state where it was when you created a backup.
BTW:The post above me came from Mars
tq very much =)
If i disable the logcat will it affect my usb debugging thing? If enable will it drains battery or memory space?

no usb debugging will not be disabled.
i use usb debugging mode only when i am using adb(for root/unlocking,etc.)
sometimes when xoom is not shown under "My Computer" then i check usb debugging and it shows.
dunno any relation with battery.
Disabling the logcat doesn't disable USB Debug Mode.
I keep debugging mode on my XOOM since I use mainly ADB for everything anyways, doesn't hurt the battery one bit.

[Q] Questions about first time installing Infused v2.1.0

Please bear with me and my noob questions. I have a rooted and unlocked Infuse 4 G. At the moment I am using t mobile monthly 4 g unlimited pre paid.
I have never done anything to the phone besides using the bml3.bk file in the hex editor to unlock the phone. I have some apps installed, and I have installed titanium back up but have not ran any back ups.
I have read the instructions but I am still confused and worried I might brick my phone. I do not have any warranty on it.
I have had others tell me that the Infused 2.1.0 and infusion 1.1 kernel running 1.6ghz would be the best way to go.
And that CMW recovery is the safest way to install it.
It says not to back anything up with titanium recovery. Does that mean that I will lose all of my apps? Or that I will lose all of my contacts or progress in apps, such as games and kindle books?
Will I lose my APN settings?
Also if I have not backed anything up, what happens if I make a mistake in the installation? Is there a way to get my stock settings back?
Also, just to be sure, I would download the zip files directly to my phone, from my phone correct? Just making sure I do not download them to my PC and then transfer them to my sd card.
Also what about the updates and beta versions? Should I use the most updated file or an older one?
Also, I do use facebook, so I can reinstall that after the ROM is installed?
I really appreciate the help and patience with all my questions.
Export your contacts to your SD card.
Myself, I backed up my apps, then restored apps & data.
(note: do "NOT". restore system data)
The apps that you have can be redownloaded if need be.
Yes to Facebook.
My suggestion would be to just install the Infused 2.1.0 first. Get used to it before going in deeper.
Yes, you can download or transfer the Infused 2.1.0 to your SD card and install from there.
Go directly to Infused 2.1.0. No need to install the beta's.
I'd say that the safest & easiest way to install Infused 2.1.0, is by using Rom Manager, especially if you're new at this.

Thank you! Is it better to download the zip files directly to sd card using my phone or using the PC? And is it safe to use titanium back up to back up the apps? And I guess I am just confused. Do I back up the apps I have that I want to keep that are not in the ROM? Or do I back up ALL of the apps I have? Im sorry, Im sure I seem like an idiot, but I want to make sure I am clear on what to do......thank you so much!
Also If I do not back up my stock system, will I be able to go back to stock if something messes up?

I downloaded them to PC and transfered them sd. Yes, its safe to backup apps with titanium, when you go to reinstall them, just restore apps and data, NOT system data. Just back all of them up, you can restore each that you want later. Just read all the installation instructions a couple of times until you understand the process. Once you do it, you'll realize its not hard. Install the ROM first, then, the kernel. If you do brick your phone, you can use Odin-to-Stock to return the phone to its stock. You'll be glad you upgraded to a custom ROM, its much faster. Only downfalls on Infused 2.1.0, (latest version) is that there is no HDMI support, and the video recording is not 30fps like it should be, but these problems will be fixed soon.
Do NOT run Infusion (or any other overclock/undervolt kernel) until you're perfectly satisfied with the stability of the ROM in question without the modded kernel.
Overclock/undervolt kernels can cause instability that may be misdiagnosed as a ROM bug.

True, only reason I say this is because they work great together. But he's right, once you install you may not like the ROM or something else, like have problems with it. You can install the kernel anytime. You will need a overclock app like voltage control or setcpu in order to get it overclocked.

[Q] Need some help installing revolver please

Ok so I have mt TF rooted, CWM with backup done, I have the revolver rom on sd so do I need to do anything special like clear caches or anything and will I lose any of my installed games or apps ? I read that on Android rev hd you have to use super wipe lite and was wondering if you have to do that with revolver.
My tablet is brand new 3.2 HC but I do have some games and stuff I dont want to lose.
Thanks for your help.
I did not clear stuff for the first time, but it is recommended - and yes, if you wipe the system you'll lose your apps, but not what's on the internal memory (/mnt/sdcard)
As davebugyi said, it is not 100% required, but strongly recommended (you could run into issues if you don't do it) if you change roms. By that I mean switch between different roms, not just update your current one. I always do it when changing roms, using the CWM clear/wipe feature is usually sufficient (unless the ROM developer says otherwise in the intall instructions).
If you want to persist apps and app data, you can try one of the backup tools such as Titanium backup. I havent tried it yet with this device though..
Titanium backup
I use titanium backup to backup apps+data then do a complete wipe. Install revelover then restore titanium backup and all your files/games etc are restored.
Thanks Guys
I will do a backup with what you recommended and wipe then install. I just hope this revolver rom is worth it. Seems like everytime you look on the forum someone post a new rom.
best rom
The revolver rom is the best. One of it's features is when you click on the history icon it gives a list of history but they have a little red x in the top corner of each. Clicking the x closes the history for that screen. Keeps yout TF clean and fast. Other roms do not have that facility.
Enjoy

[Q] now rooted, few questions regarding apps

i've rooted my device with the Exynos exploit and installed titanium backup pro but i am not sure where to start when it comes to transferring app data to a sd card, any tips? can anyone recommend me some app data to sd apps that are simple to use and does the job?

Now that you have root you have 2 options I'm aware of for our device. What your trying to accomplish is a link between your actual data folder where apks get installed by default on your internal memory to a replicated directory on your external storage. The device will install data to its default location but then this link will just move it for you to the mirrored directory. Zedomax and tweaker have both made a script to do this. Tweakers script seems to be a cleaner better method but is more user intensive to implement. Zedos script, which im using now is simple to use and it gets the job done. I've had no issues using it on any rom that has init.d support. Stock firmware will not work however, even with root so you'll need to install a rom with init.d support. Theres the recent stock jelly bean in android dev that has this now. Also our dev community has been busy and you got a few choices if youd like a custom rom as well.
To make that happen youll need a custom recovery that youll install with a pc program called odin. Thats a simple procedure shouldnt take more than a few minutes. Also you could do the same with an android app called mobile odin though I haven't done it this way myself so I may not be the best person to ask how. After the recovery has been installed youd want to backup your stock rom then flash your init.d supported rom of choice after a full wipe, then once thats completed flash zedos script, reboot and then everyones favorite: profit!!
If your still reading this at this point and thinking youd like to give it a shot let me know, I can point you to the relevant threads and maybe fill in some blanks on some areas where you need to read between the lines. Good luck and know I think its worth the time my redemption install is terrific, definitely an improvement over stock jellybean imo.
