How do I root my phone ? (I've read your guides but they are CONFUSING!!)

Here is my experience with all this and why I need help ..
(Yes, I am new to all this, maybe that's why I get confused but alright..)
Okay, I want to root my phone with the design of DocRambone. Right, I follow your guide here:
http://forum.xda-developers.com/showthread.php?p=7329960#post7329960
And go to HOWTO#1 which says I need to flash my firmware. And so I start.
I first download Odin, get the 512.pit file and then try to find the desired firmware package(which according to the Doc guide is I9000XWJM8). Okay, I search the link and get to this: (I pick original firmwares -> Europe)
https://www.wuala.com/Samsung Galax...n/Original Firmwares/Europe/?key=AfzUZSU4SpKU
Which leads to my first confusion. I can't find anything named "I9000XWJM8". The closest I find is the one called "GT-I9000_I9000XWJM8_I9000XXJM4_CODE-MODEM.7z". Can I use this one or where is the "I9000XWJM8" ? :S
Right, I then assume it's the right one and continue only to find out that I don't know how to start my phone in "download mode". Or maybe I just can't because I got one of the phones without the 3 button combination. I'm not sure which one it is, and yes I did try all the combinations you state here:
http://forum.xda-developers.com/showthread.php?t=746814&page=2
None works. But how does the screen look like when you are in recorvery mode? Maybe you should add this to the guide, so people know if they can or cannot start in recorvery mode.
Anyway, I assume I have one of the phones without the combination and so I continue to the guide "Release: 3-button combo fix for any firmware version":
http://forum.xda-developers.com/showthread.php?t=785201
I follow the guide and get to step 6 which says "Start a new command prompt and type "adb reboot recovery"". Right, what's this now?
I go back to the big tutorial:
http://forum.xda-developers.com/showthread.php?p=7329960#post7329960
And finds the ADB tutorial to find out that I need Android Software Development Kit .. AND a rooted phone. Right, so I wanted to root my phone in the first place and now I need to root the phone in order to get the 3 button combination so I can root the phone. "Wait what?" was my 1st thought. But then I remembered that I found this guide earlier "[REF] Howto (un)root your SGS I9000 the easy way (keep all your data) (Eclair 2.1)":
http://forum.xda-developers.com/showthread.php?t=728754
Why did I got here? Because it said "the easy way". I thought that maybe it doesn't need the 3 buttom combination and so I found out it doesn't!! YAY finally a breakthrough, I thought. And so I started with this tutorial.
I was then met with this
"ROOT includes:
- Superuser 2.3.6.1
- Busybox 1.16.0 (for use with Titanium Backup)"
which brings me to another question: Does this mean that you get these apps when you use this root method? or do I need to install the apps first?
I thought it was the first one, since it says "includes". And so I start with the "Automated Method!". I dowload the .bat file and start. Follow what it says and reaches to the part where I plug in my phone. Here I get the error message: "Driver installation unsuccessfull" (Or something like it. I Don't recall since when I plug the phone in now I don't get the error. I don't even get a "ready to use removable disk" now. It doesn't even recognize the phone now when it's plugged in). Now I have tryed to connect it to the pc before (although WITHOUT the USB-debugging checked) and it worked fine. And this is as far as I can get. I am now officially stuck!
I have read comments and all but it doesn't help.
I'm realy tired from trolling these forums after being led through like 4-6 guides + the ones I havn't mentioned here (havn't counted, but something like that)..
So can anyone please, for the love of god, tell me which guide I should start with, list the guides so I know which one to go to next and answer the questions above.. My head hurts now :S ..
But in general, please write the guides more "noob friendly" or whatever .. I think alot of them are written by admins for admins(or atleast people who know their way around these phones). Atleast that's the impression I get.
I know it was a long read but I hope you'll help anyway
Thank you in advance!

hello there, I can appreciate if you're new to smartphones it can seem a lot to take in.
If you want an easy/simple way to root then there are 2 or 3 methods available on this fantastic forum but try this one:
http://forum.xda-developers.com/showthread.php?t=742403

just go to youtube and search for rooting videos and watch someone do it first, then you do it. very easy once you see how it is done. youtube or theunlockr.com also has great videos

Yea but my problem is now that I can't get access to it when it's in USB debugging mode.
As I posted earlier, the first time I put my phone in USB debugging mode and connected it to my computer it said "Drivers where not successfully installed" (or something like it).. And now, when I connect my phone to my computer in USB debugging mode, it won't even show as an USB. It doesn't pop up and say "USB connected" and I can't find it under My Computer.
Someone who can help me with this?

And when I plug it in, in USB debugging mode, should I press the USB connected button on my phone, like I usually do when I connect the phone to my computer without it being in USB debugging mode?

Okay, I found the device now on my computer, but I can't find any drivers for the phone to be connected in USB-debugging mode. Anyone knows where I can find drivers for this?

when used as USB Debugging mode, you need no driver if you plan to use it as a mass storage drive
you just pull down the tab and select mount the drive
then you can copy your Update.zip to the phone Internal SD
after it is done select Unmount the mass storage drive from the pull down tab in the phone
and now you can boot into the Recovery Mode, select update.zip
and you are rooted.
reboot back to normal, and enjoy the freedom to install any App you want to play with

The easiest way I found is to go on to Android market, install One Click Lag Fix. Then open the app and select root 2.1. Restart into recovery and select apply update.zip. Your phone reboots and its rooted. Simples!

simplest way to root is
1)go to market search for RyanZA's OCLF 2.0.
or here is link http://www.appbrain.com/app/com.rc.QuickFixLagFix
2)open the app
3) click root.
4)then boot into recovery
5)use volume button to select update.zip and click home button
6)your phone is rooted.

Hi everyone... Can anyone here let me know if these "lagfix" rooting methods work and are SAFE for a LOCKED (I have not unlocked the sim) Bell Galaxy S with stock JH2 rom? I am also a bit of a noob and would like to see what this phone can really do.
Also... Do I have to unroot it if I want to upgrade to froyo when it is released?
Please advise...
Thx.
yiannisthegreek
PS... Once this is rooted, HOW do you unroot with these "lagfix" methods if I ever need to?

i would advice againts installing the LAG FIXes as they can kill your Internal SD
there are over a dozen forum topics with people unable to repair the damage, and end up having to ship the phone back to samsung to have it repaired.

Allgamer...
Thank You for the heads up on this but now I am still confused on how to do it. I have to move the update.zip file to my internal sd card but I too have some issues that I cant figure out.
I learded how to do it on youtube watching someone called tech0stickyasglue and it seems very simple but firstly I am not sure exactly where I have to place the file and if I have to unzip it and then place the 2 folders inside it into the sd card, etc... I also have an issue with the whole "mount" and "unmount" thing.
I can mount the card while in usb debugging but when I go back to the dropdown menu it does not give me an option to "unmount" it only gives me an option to quit usb debugging and when I pick this option I get a warning message saying that I should "make sure I have unmounted form the host" or something to that effect.
Can you give any advice or step by step instructions to me on what and where I need to place these files to make this work?
I would greatly appreciate it...

Yea but the thing is that I can't go into recorvery mode.. The 3 button combination doesn't work (Talking to the people from page 1)

When I put down the tap and select mount the drive(when in USB debugging mode that is) I can't acces the phones folders. I can't even see the extra icons you usually get, under My Computer, when you connect an USB to the computer. I can only find the SAMSUNG_Android under Control Panel -> Hardware and Sound ->Devices and Printers where it lies under the "Unspecified" section and not under the "Devices" section. And when I right click on it, press proporties and go to the Hardware tap, I can see under "Device status:" it says "The drivers for this device are not installed. (Code 28)" ..
So can anyone tell me what's wrong? (I havn't installed Kies btw, dunno if that has got anything to do with it)

Ahh... the joy of Android & Kies....
you don't really need to install Kies, I only installed Kies to check for official ROMs, but i was using the phone on the PC even without Kies installed
You can install the Android SDK drivers, inside the Android package that you download from google, there is a sub folder with both 32bit and 64bit drivers, unplug your phone and install them, then plug back the phone, it should be detected now.
in my Work PC, i never installed any driver, and i select mount, and it gets detected as a USB key by Win XP

Alright, thanks alot But where can I find this Android package then? I'm not sure what you are talking about exactly

Why wont anyone explain WHAT file(s) you put WHERE exactly for this update.zip root method? Is is some sort of "spy secret" or something?
Seriously... I CAN get to see my phone folders on my computer so I am good there but what I dont know is if I am supposed to move the entire .zip file to the root of my sd card or if I need to extract the .zip file to the root of my sd card.
At any rate... I have tried BOTH methods and I always get the same error message when I reboot in 3 button mode... Something to the effect of E: cannot open / install update.zip... Invalid or not found... (I am guessing on this as I am at work but you get the idea)...
Please... ANY help and "step by step" instruction would be GREATLY appreciated!!!

Hi,
One Click Lag Fix (OCLG) downloadable from Android Market will give u an option to root ur phone. And also it gives u an option to fix the lag in galaxy s. I have more than 80 applicatons and widgets installed in my phone. I insist that OCLF is the most useful, powerful and demanded application ever. It is so easy to use and follow. It even offers an option to unroot. So don't be afraid to download and install.
For ur reference, the bench mark speed has been increased from 800 to 2150. Comparable to nexus 1 with 2.2 was 1200. Hope this helps.

[Q] USB Mass Storage Device driver failed

Bought a LG P970 Optimus Black.
Installed LGMobile Support Tool into my
Windows 7 64bit.
Installed the LG 3.2.1 drivers using LGMobile Support Tool.
Then, I connected the phone to the computer.
Result of drivers installation:
LGE Android Platform Composite USB Device - Ready to use
LGE Android Platform USB Modem - Failed
LGE Mass Storage Device - Failed
LGE Android Platform USB GPS NMEA Port (COM6) - Ready to use
LGE Android Platform USB Serial Port (COM7) - Ready to use
I wasn't planning to use the phone as a modem, so that driver does not worry me, but the USB storage problem is annoying.
In the phone, it does look as it connected. It offers the option to activate USB storage on screen, and if I click on the button, it says it enabled it, but nothing happens in the computer side.
I tested to uninstall everything LGE from the computer and restart from scratch, but same problem.
Ideas?
Update:
The LGMobile Support Tool in Windows says the phone IS connected, and that the software in the phone is up to date.

Do You see the phone into section computer like Removable Disc?

No. Nothing at all.
In "Devices and Printers" I have:
Under Devices:
LG Android Phone
LG Android (Modem)
LG Android (Serial)
LG Android (NMEA)
Under Unspecified:
LGE Bluetooth TransPort (COM4)
LGE Virtual Modem
In the "Device Manager" I have 1 "USB Mass Storage Device", with a yellow warning sign.
Under its Properties, in Device Status, it says: "This device cannot start. (Code 10)
If I try to "Update Driver" Windows says that the right driver is already installed.

FIXED !!
Updated LG driver to 3.5.
Still didn't work.
Then, I turned off the phone.
Removed the battery.
Put the battery back.
Turned on the phone.
Connected it to USB.
This time the USB driver started ok, and when I activated the USB storage I was able to see the drive under "Computer" in Windows Explorer.
I had turned the phone off and on before, so I think removing the battery did something that simply turning off and on wouldn't do.

USB 3.0 External Storage Device driver not getting Installed- [Solved]
Issue: USB storage device is not working on my computer, be it a USB 2.0 or USB 3.0 it just doesn't install the driver for storage device and my USB mouse and webcam does work.Everytime I plug in a USB flash drive of USB 3.0 External hard drive it beeps and gives error message that the device driver could not be installed.
Here is the steps I took to troubleshoot this issue and it got fixed.
1.Open registry by going to Run-> Type Regedit.
and Navigate to the following key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{36FC9E60-C465-11CF-8056-444553540000}
Highlight this key ({36FC9E60-C465-11CF-8056-444553540000} ), on the right pane, and then check if “Upperfilters” and “Lowerfilters” value are present. If so, please right click on the values and select "Delete" to remove them.
2. Now go to "C:\windows\inf" folder and check if these three files USBSTOR.SYS, usbstor.inf and usbstor.pnf are available.If it was renamed change the name as I wrote them or if they are not available copy them from "C:\windows\System32\DriverStore\FileRepository\usbstor.inf_x86_neutral_83027f5d5b2468d3"
And then go to "C:\WINDOWS\SYSTEM32\Drivers" and make sure you have USBSTOR.SYS and usbd.sys available if not copy them again from
"C:\windows\System32\DriverStore\FileRepository\usbstor.inf_x86_neutral_83027f5d5b2468d3"
and paste it to Drivers folder.
3. Open Registry editor by going to Run-> typing Regedit and Navigate to the following key:
"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR" and ensure that the Start value is 3. and restart the system.
It will work..

thx

[DRIVERS] Nexus 4 Driver for Windows

If you have windows, you will need these drivers to use ADB or Fastboot with your Nexus 4. The long method of getting this is downloading the SDK and running it. I have extracted the drivers and put it into a rar file for easy use.
Follow these steps if you haven't plugged your phone into your computer before.
1. Download the file.
2. Extra the files into a folder.
3. Plug your phone in.
4. When prompted, select "Let me pick from a list of device drivers on my computer", NOT "browse for driver software on your computer".
5. Then you have to select "have disk" and then point to where you extracted the drivers (the usb_driver folder) to install the drivers.
If you already installed other drivers and they don't work for you. Download the drivers below and follow these steps:
1. Enable USB Debugging on your phone.
2. Plug your phone into your computer.
3. Go to Device Manager on your computer and locate your device. It will either be under "Android Devices" or "Other Devices" depending whether drivers have been installed or not.
4. Right click on your phone and select "Uninstall."
5. In the box that appears, check the option to "Delete the driver software for this device" then proceed.
6. When that is done, go back to Device Manager and refresh.
7. Locate your phone and right click to select "Update Driver Software."
8. When prompted, select "Let me pick from a list of device drivers on my computer", NOT "browse for driver software on your computer".
9. Then you have to select "have disk" and then point to where you extracted the drivers (the usb_driver folder) to install the drivers.
10. Unplug your phone and restart your computer.
11. Plug it back in and everything should work.

Thanks to efrant for clarifying exactly how to manually select your drivers.

I would suggest everyone download Android SDK.
You have a Nexus device right?
http://developer.android.com/sdk/index.html

Some people may not want that, or want to have the drivers on their other computer. I for one like having the drivers, I only download the platform-tools folder instead of the whole sdk.
So, thanks OP.

OK... I DL the SDK I'm on win and it says it can't find java even after I DL from java. Any ideas?

Yep, I never needed the whole SDK before. I only download the platform tools too.

Have any other ADB drivers installed? Because then you need to uninstall those:
Go into command prompt and write:
set devmgr_show_nonpresent_devices=1
start devmgmt.msc
Delete all devices including driver software in the "Android Device" section.
Then reinstall the Nexus 4 drivers.
If that still doesn't work, update the driver when connected with usb debugging on and manually add by rightclicking the device, click update driver software, then the "Browse my computer for driver software", then "Let me pick from a list..." then "Show all devices" and then Have disk.
Then you simply point to the driver and select the "Android ADB Interface" (Or something like that) it also has driver for bootloader and composite, bootloader is for fastboot, can't remember what composite is for, but you shouldn't use those.

the stuff from Fisker didn't did it for me
the driver is installed and the device is in debug mode,
but i can't see in adb devices,
any idea?

Go to Device Manager on your PC. If debug mode is enabled, you should see your device listed as an Android phone or something of the sort. If it has a yellow exclamation mark or some sort of symbol next to it, then that means the drivers aren't properly installed. Assuming that is the case, follow FISKER_Q's directions:
Right clicking the device, click update driver software, then the "Browse my computer for driver software." Select the usb_driver folder that you extracted and you should be good to go.

Did you enable debugging on your phone yet?
If not, go to Settings > About phone, then tap on "Build Number" 7 times. Go back to settings and you will see developer options. Go in there to enable USB debugging.

Having the same issue. Fastboot works fine, however I am unable to use ADB (device not listed, however is recognized in device manager without any issues). I have tried uninstalling the drivers, but it re-installs them automatically when I plug the phone back in. Debug mode is enabled.
Edit: Fixed by uninstalling the drivers through the SDK manager, then uninstalling and checking the box to delete the driver software in device manager. Re-installed using instructions and now it works in ADB.

Try leaving the phone plug in. Go to Device Manager. Find the ADB drivers and uninstall it. While in Device Manager, have it scan for new changes. You should see your phone appear. Right click it and manually install the drivers.

Make sure USB Debugging is enabled through Developer Options on your phone. Once done, plug the phone into your computer. Go to Device Manager on your computer. You should either see something listed under Android Devices or Other Devices. If you see something under Android Devices, uninstall it. If you see it under Other Devices, right click it and browse to manually install the drivers. Select the folder that has the drivers in my original post.

I had to put a check in the box next to "Delete the driver software for this device" to get this to work. Otherwise Device Manager will keep detecting the old drivers.

I - Install APX (NVFlash Recovery) Drivers if not already installed. It starts a device driver wizard to help you install the drivers needed for NVFlash. It detects your system OS and gives on-screen instructions if running Windows 8. FYI the drivers are located under ToolKitFiles\nvflash\driver folder.

Prepare Phone
-Power down phone
-Remove battery
-Hold VOL_DWN+VOL_UP & plug in USB connection from computer (note, your phone will not visibly respond but it will boot to APX mode quickly)
-Open Device Manager in Windows and you should see "APX Device" listed with an error, or not if you have used NVFlash before
-Right click on the APX device
-Select 'Update driver software'
-Select 'Browse my computer...'
-Select 'Let me pick...'
-Select 'Have disk'
-Browse to directory you extracted the *driver* software to above (It's included in Stefan's zip)
-Select 'NVIDIA USB Boot-recovery driver for mobile devices'
-Accept any warnings, including the big red alert (you may need to disable UAC)
-Now in Device Manager under 'USB Controllers' you should have an 'NVIDIA USB Boot-recovery driver for mobile devices'
If not, uninstall the driver, reboot, rinse and repeat
Install the rom:
- Go to the folder where you unpacked Stefans rom
- Run Windows installer and follow instructions on screen, should be peace of cake for everyone!
- DONE

I think you should try either updating your drivers for the phone and if that doesn't work, try an older version then.

[Q] need help if someone can...

ok i tryied to use all in one tool and i want to flash to ics to my thrill but as far as i got is on the tool it goes to stage 2 but waiting for device stays there even after i do place to battery in it.. it acts all over again as if it cant find the driver for cosmo i think that is what it is called....but im running windows 7

When it says waiting on device try pulling out the usb and then plug it right back in. I use to have to do that, but if that doesn't work then it may be a driver issue.
Maybe start the tool and when it says waiting for omap4430 device, hold down vol+ and plug in your phone but don't let go of vol+. Pop in battery like normal and it should boot you into download mode. See if that helps get your LG Cosmo driver to install, though it should install as LGE CDMA USB SERIAL PORT. if that doesn't happen, as a last resort uninstall all LG mobile drivers, reboot cpu, download the files from step 1 and step 5 of this post---> http://forum.xda-developers.com/showthread.php?p=39269819 (bag of goodies and wkparks 1.21) Turn off your anti virus and windows defender before doing anything. Once thats done unzip the two files mentioned above. Run the omap flash installer and re install both Sets of LG mobile drivers in the bag of goodies package (second set will pop up a warning for unsigned drivers a few times; hit YES do it anyways, and then re install omap by directing the driver update to the windows drivers folder in the wkparks bootloader1.21 tool. Hopefully this helps.
Here is a much better explaination from drastic00's tutorial. Follow these steps to the T and you should be flashing in no time
" A) Uninstall any LG Drivers:
a1) Open Programs and Features through Control Panel
a2)Find any drivers called "LG United Mobile Driver." Right click and select Uninstall, let it work.
a3)Reboot your pc!
B) Be sure you disabled antivirus/Windows Defender, etc. before unpacking these files.
C) Install OMAP4430 by running "OMAPFlashInstaller."
NOTE: if you have Fastboot installed SKIP this step (if you don't know, you don't have it...), but DO link the driver as in f4.
D) Install the two LG Drivers in the “LG United Mobile Drivers” folder: These are “LGUnitedMobileDriver_S497CA20_WHQL_ML_Ver_1. 0” and “LGUnitedMobileDriver_S497MA20_WHQL_ML_Ver_1. 0” The second one will warn it is unsigned, choose to install anyway (you will have to insist on this a few times here).
E)Reboot your pc!
F)Install PC/phone drivers:
f1)Shut down your phone. Remove external sd card, SIM card and battery.
f2) Open Device Manager from Control Panel
f3) Hold volume up on phone and connect to USB port. Keep holding volume up.
f4)Look for "OMAP4430" blinking on and off in Device Manager with a yellow question mark under "Other Devices." (You can let go of the phone). If you do not see it, look for "TI Boards" blinking in device manager and quickly open the arrow. Then uninstall that OMAP4430 (right click, check box to uninstall device and driver, confirm), disconnect phone and reconnect with volume up. Then...
f.4.1) You will need to 'catch' OMAP4430 (with yellow question mark) by right-clicking on it when it appears under "Other Devices." Choose "Update Driver Software."
f.4.2) Pick "Browse my computer for driver software." Then "Let me pick..."
f.4.3) Leave "All..." selected under Devices. Then "Have Disk."
f.4.4) Navigate to the omap4boot-for_optimus-v1.21 folder and choose "omap_winusb" in the usb_drv_windows folder.
f.4.5) Windows will warn the driver is unsigned. Install anyway. An OMAP4430 device should appear under the list of devices. Confirm the selection. Let the driver install.
f.4.6) Disconnect the phone and again reconnect with volume up held.
f5) You should see a popup at the bottom of your screen about drivers (the LG USB drivers) installing. (If you do not see it, disconnect phone, reboot your pc, and again connect it without battery while holding volume up). When you do see drivers installing, let go of the volume button. Click the popup to see the progress. Let it finish.
f6) Look for “LGE CDMA USB SERIAL PORT” in Device Manager. Right click on it and go to Properties
f7) Select the "Port Settings" tab and click 'Advanced'.
f8) Change 'COM Port Number:' to COM41. Click OK, then OK again.
f9) Disconnect your phone from the PC." (From drastic00's noob tutorial)
