What are you running (kernel + rom) at the moment?
And why do you want it removed?

im running everything stock,
installed just to quickly test so praised ArcMini custom rom. So i restored the backup later on because i didnt liked custom rom.
I felt that the battery drains a bit quicker now, i re-recalibrated and still feels like battery does drain faster than was before.
So i suspect its because i installed CMW.

its more likely apps that are running in the background and widgets you have on the desktop, try a different rom such as lite version of cm7 and underclock your phone,
as far as my understanding goes, cmw is just a tool for installing roms backups ect and doesn't run when you are using it much like booting into a recovery panel on a pc possibly, basically it should not effect your battery drain, though I may be wrong,
I hope this help

no its not apps, because i did backup and restore and after restore battery drain started happening. If i didnt changed anything except installing CMW what else couldve cause that ? every app and configuration was the same...
no custom roms, i have tried and stock rom wins all the way except the extras 2.3 has, but still stock is more stable and graphicly better looking
so is there a way to remove ?

you could re-flash the original kernel, via flash tool, this will get rid of CMW and set thing to how they where, if you are using a custom kernel or stock kernel with additional modules that could also be responsible for your increased battery drain, you should be able to find the stock kernel on this forum as others have asked for it, alternatively I thing there is a way to get the stock kernel from pc companion
good luck hope this help

well im already using stock kernel...
thing is i dont want to reinstall OS i just want to remove CMW reinstalling os means i have reinstall apps and again link to link2sd

Installing CWM installs Chargemon, Charger and Recovery.tar to /system/bin and 'sh' to system/xbin. I'm fairly sure chargemon and charger are custom replacements to files that already existed, so i'm not sure removing them would be wise. you can remove Recovery.tar though, which is the main CWM program. Not sure if the 'sh' file in system/xbin is safe to remove either, or what it does exactly.
In Roms that run on kernels that have CWM built in, the chargemon, recovery and the 'sh' file are not present in the ROM, so they may be safe to remove.
Make sure you keep backups of those files, or just rename them at first (just add a 2 at the end of the filename should disable them) to see if it leads to any problems, before you remove them altogether.

sh is the shell. It's installed by default and I wouldn't recommend removing it under any circumstances

Is it possible to make a custom rom from an already running system?

Is it possible to make a custom ROM from an already running system? Some manufacturers don't update their phones (believe me, there are those minor companies that don't care at all), and users would be stuck to their stock ROM.
Soo, is it possible? Will copying all files from the root partition to the PC, modify with the usual tools, then zip, then flash, work?
Just curious
It's possible to work with a nandroid if that's what you mean, yes.
By the way, you shouldn't underclock your Optimus. That'll drain more battery, trust me, I did the same.

How about not using a nandroid backup? I was thinking this would work because I had a look at the contents of the root directory of the phone, and then I had another look at a custom rom zip on my computer. I may sound stupid saying this, but I'm just curious xD

I've left the values as it is, but I forgot to update my sig. Anyway, thanks I uses the same power if the voltage isn't changed, right?

[Q] Not your normal tether question

OK so this probably sounds backwards from what everyone would expect. I've been using attn1's Liberated 2.2.2 FR008 rom and adding/removing apps to suite my needs. But now I want to REMOVE usb & wifi tethering! Sounds crazy but this phone is for a kid. I don't know much about developing. I'm guessing these features are built in to the OS, if so do I need to just get a custom settings.apk that doesn't give the tether options OR is there an apk i can remove (many of the apks in that rom have name that I'm not sure what they do so I left them in)? Any help would be really appreciated!

I guess you'd just have to get a new rom which does not have those options (none that I know of), but I still don't see why you need those options removed. Even if it is for a child, it doesn't really make a difference. The options can still be there and just not be used.
didnt the stock 2.1 NOT come with tethering? Its been a while, but I think thats how I remember it. So couldnt you just revert to a 2.1 rom?

Right, but I can't figure out how to remove the junk apps ect. from the RUU before flashing it like I can with a custom just by deleting apk's from the .zip file. Any ideas?

I'm no dev but i think if you flash back to ATT 2.1 Rom and re-root to get super user i think you'll be abel to delete your ATT softwear with titanium backup... but I'm not sure. I hope this works for you

you can use adb to remove the apk's from the /system partition while the phone is in recovery after you flash the stock 2.1 RUU. You may have to reflash clockwork recovery after this, not sure if it will revert to stock recovery or not. Also, not sure on this one but you can check out the 2.1 Liberated Rom in the dev section and see if it has tethering enabled or not. Trying to remember this off the top of my head but its been so long since Ive done anything 2.1...
Yes, running the 2.1 RUU will remove Clockwork. So the full process would be to run the 2.1 RUU on the phone, then once done, run Unrevoked again on the phone. At this point I would recommend taking a Nandroid backup so you can revert any changes you make (i.e., if you have problems after deleting one of the apps).
Then you need to use adb to remove apps while the phone is in Recovery mode.
The downside of this (compared to just leaving the phone with stock 2.1 after using the RUU) is that Unrevoked automatically gives you root access in the ROM, which may or may not be what you want.

Root access to the rom is fine. But if I remove apks using adb aren't they still in the boot.img making it possible to simple do a system wipe/ hard reset and thus bring back all the junk apps in the stock 2.1 rom??
With all the DEVS on here it seems like there is a cleaner way to do all this...

No. System wipe would not revert the apps.

[Q] Urgent Help! Restore CPU Settings!

Help guys. I rooted a buddys fascinate. Had a backup but I accidentally wiped that too.
We were comparing phones and I had him run Quadrant and using ROM Toolbox I had him slide his CPU all the way up. Phone reboots now about a minute after you boot into the phone. Not enough time as its still loading/media scanning to get to the app and turn sliders back down.
I thought ADB would work through CWM and I could pull the app but that didn't work.
I flashed the same kernel (KGB over a touchwiz ROM) on top of it hoping it would reset but no luck.
What are my options?
reflash the rom

i have. it still reboots about a minute after booting - i assume because ROM Toolbox is still there trying to set CPU?
Edit: also, i'm a little surprised i wasn't able to ADB through recovery? It was on the same laptop i rooted it with so I'm sure the drivers are there. Wire is OK as I was browsing the SD card.
Edit #2: ok i'm losing my eyesight. last night i saw a link to a stock eh03 kernel I was going to try. I figure if the kernel doesn't support OC'ing, i could get in. uninstall the app and flash the KGB kernel back. can you point me to the stock kernel or at least one w/out OC'ing support?
(hes running TSM EH03 btw)

So you three fingerd into recovery, wiped data, reflashed TSM and still no dice? If so, then follow section 2 of my guide.

your going to have to wipe data unfortunately...hopefully his contacts are synced with google and apps backed up with titanium backup. You could try pulling the sd card and putting in a pc to get contacts, pictures...etc, but the phone is going to need a data wipe.

where are contacts stored then?

Edit* Not sure where the contacts are stored, somebody can hopefully chime in there.
Also one thing you could try is going into the sd card via pc and deleting the rom tool box app in system/app folder. I have not tried this before...so it may or may not work! You can try flashing the stock kernel, but Im not sure if that will do anything either. Never really been in this situation since I keep all my stuff backed up.
droidstyle said:
No because the kernel dont overwrite the app data...your OC app(rom tool box) still has the voltage script written in the initd folder and the stock eh03 kernel is capable of being OC'd...so nothing will change there.

DAMN IT.
Voltages? I didn't change voltages. Just CPU Sliders. Think the nstools reset zip might work?
Also, I followed you guide to flash TSM, so I'm pretty sure its running CWM 2.5.1 (its all red). Shouldn't I be able to adb in through recovery and take out the init.d script/modify text values for the CPU/Pull the ROM Toolbox apk/etc?
Edit: YES YES YES.. sd card via PC.. but.. how do I get to the /system/app through SD card on PC while in recovery. All I get is the SD card contents?

Im sorry I meant mhz not voltage lol...
scratch the sd card idea, you cant access the system from pc.
If you are familiar with adb, then yes I believe what you said above will work. One thing tho, stock kernels do not support init.d scripts. So if your on the stock kernel, the rom toolbox app must be applying the OC on boot. I think your best shot is to pull the RTB.apk via adb.

I haven't tried stock kernel yet. So if it doesn't support init.d, and thats how its being set - seems a valid theory that flashing it would get me back into being able to boot OK.
Whats RTB.apk?
And any ideas as to why I can't adb in when in recovery? Just a driver issue you think? I used the same laptop to root his phone so i figured drivers would be good, so I didn't explore that much last night. USB Mount worked OK obviously.

(ROM TOOL BOX. APK) lol
If rom tool box is setting the OC at boot and not using init.d script, then no flashing a stock kernel wont fix it.
The samsung driver you used wont work with adb, you need the nexus google driver. A simple Google search will pull it up.
Fyi, the next time you run into issues, a full detailed writeup on the devices setup and exact methods used to get there would help alot.

[SUGESTION TO DEVS] Make roms for locked bootloaders

Hello all devs, I have a suggestion that I think many people that cant unlock the bootloader will think very nice.
The sugestion is that the devs if they time to make a version like JJs hybrid rom for locked bootloaders.
I have also tried the Miui rom, and I removed the format script and boot.img and it booted fine without any major problems.
So my sugestion is that the devs makes their roms for stockkernel for people with locked bootloader, and makes a deletion script that removes all the files from the old rom.
Devs, what do you think about my idea?
Thats not possible to remove format script...
If you dont format system partition, it will be overloaded with applications and frameworks from Old and New ROM... the two ROM appz might not share the same sign keys... that would result in Bootloop or Series of FCs on install...

Here are a solution that I think maybe works:
First create a homemade format script that removes all the stuff on partiation, but it doesnt run the format options, it just deltes everything manually from recovery.
And then just remove the format script from the roms zipfile and remove the boot.img too.
Then just resign the zip file with sign by enyblock.
Thats should work, maybe somebody can try it?

thats practically not possible either...
MIUI, CM9 have different appz and framework...
applications aside, who has enough time to write a delete script for more than a thousand lib and other system files?..
I am trying to find out the files that don't load on statup after installing a flashable zip on Locked bootloaders... that is better way of finding a solution..

This is why most custom ROMs require custom kernel
Needs unlocked bootloader
(actually hybrom does not contain a boot image.Thus, when you install hybrom you don't mess with your boot image at all.BUT recovery from nAa is installed in /system and while system is formated during the installation of hybrom,recovery messes with it self.That's why unlocked bootloader and a custom kernel with recovery is necessary for now to install hybrom)

It means, that if Recovery is installed in /system folder, and you want to install custom ROM, which (mostly) replaces the system folder, Recovery would be removed and would end up in complete stop with bootloop.
If Recovery is installed in the kernel, then the whole /system partition can be removed without affecting the Recovery at all.
Also, stock kernels have quite low functionality, that's why it is not widely used.

Yeah, about the boot.img, can we dont just mod the chargemoon to load the rom?

Loading the ROM is not the problem, it is the functionality.
Modifying stock kernel can be done, but if you want to make it work, you have to unlock bootloader to install it also.

[Q] What should I Back Up?

So now that I have root on my phone, using Titanium Backup, WHAT should I backup? I mean... my phone doesn't have inherent instability now does it?
Or does the instability (possibly) come from xposed modules I install?
Are there sets of steps I should take before installing new root apps?
Thanks!
-Matt
Root details:
Verizon S4 (sch-i545)
Stock ROM (4.4.2)
Back up anything you would miss loosing if something happed. For me thats nothing, for others thats maybe a particular apk version, or an apps data.
What do you need to do before installing root apps? Root apps are just programs that require admin rights. Nothing magic, do whatever that app might need, which is probably nothing.
It is generally good to have a full system backup from your recovery... For when you try to do _______ and **** it up.

Okay great! I already backed up any folders (pictures, pdfs from camsacanner, roms) to my computer via usb before rooting... so...
So when people are talking about TWRP/CWmod recovery... how is it different from stock recovery?
So basically a custom recovery is an all in one answer that allows you to back up EVERYTHING but also allows you to back up EVERYTHING in one blow?

Stock recovery will let you do a factory wipe to basically clear data and reset your system to recover from something that messes up your install and makes your phone unusable.
Custom recoveries allow you to flash unofficial files, as well as take basically a snapshot of your system. With a custom recovery you can make a backup of your phone, and almost no matter what happens, you can flash that backup and it will be like nothing happened.
So when you try and run some xposed module that isn't written well, and now makes your phone crash every 2 minutes, you can boot to recovery and flash back to the backup you took right before you installed that module, and it will be like you never did it.
The recovery images are kinda large, as its all your data/apps/the OS all in one. Many custom recoveries will have a file manager that will allow you to deal with files individually, but most typically the point is taking a snapshot of your current system so you can go back to it. I make backups before trying a new rom, that way if after a little bit I am not happy I just flash back and its like I never changed anything.
