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.

How to root your Legend 2.1 (updated febuary 14th)

I'm writing this becuase i recently had trouble following other guides rooting my Bell and Virgin (canada) htc Legend with 2.1 on it (2.2 is out here yet)
First follow this guide
[HOWTO] DOWNGRADE to 1.31 which you can then root for Legend 2.1
http://forum.xda-developers.com/showthread.php?t=725430
Click to expand...
Click to collapse
(By now your should have adb set up and your gold card)
If it dosnt downgrade and shows that it fails its okay just move on
After following downgrade guide and it failing install temp root
the best way is to get the apk is to go to this link in the android browser
goo.gl/TcP1o <---Download link to visionary apk
In the web browser open downloads and install the visionary apk
Then connect your phone to your computer open cmd.exe and via adb get root
with cmd.exe
go
Code:
cd c:\AndroidSDK\platform-tools\
for me adb is under platform tools, if you dont update the sdk it is under just tools
then
Code:
adb shell
a # should be at the bottom line, then type in
Code:
su
This gets you root, if it says denied run the visionary app and try again, then
Code:
/data/local/flash_image misc /data/local/misc1-2.img
Then for the actual root
Flash the Rooted ROM1. Download the Rooting Tools
Legend Rooting Tools:
2. Unzip them to the C: drive on your computer (so the file path is C:\r4-legend-root\)
3. Turn off your phone and turn it back on by holding down Back and Power until you see Fastboot come up on the screen. Push the Power button while highlighting Fastboot on the phone and Fastboot should show up in red now on the phone (if it doesn’t push Power again until it does).
4. Plug the phone in via USB cable to the computer.
5. Open the folder you extracted to the C drive and double click “step1-windows.bat” and wait for it to finish.
6. Once you see the menu on the phone come back up, navigate to BOOTLOADER and push power, then navigate to RECOVERY using the volume buttons to navigate and the power button to select and the phone should boot to the ! screen.
7. Now on the computer double click the “step2-windows.bat” file and wait for it to finish. (UPDATE 12.13.10 – You MUST have HTC Sync version 2.0.33 not a newer version for step2 to work. Please uninstall HTC Sync and download and install this version instead, unplug then plug your phone back in, then rerun step2-windows.bat).
8. Now you should see a custom recovery screen, using the optical trackpad navigate to Wipe and push on the trackpad to select it. Then navigate to Wipe data/factory reset and select that.
9. Once that is done, push volume down to go back to the main menu and select Flash zip from sdcard and select the rootedupdate.zip file and wait for it to flash. All done, you have root access and can use any root required app! Enjoy!

Hello, Having some trouble here.
I got to the step where you run the Step1 batch file from windows. The cmd prompt comes up and says "erasing cache....." then sits. a few minutes later. i get
"FAILED <status read failed <unknown error>>
< Waiting for device>
During the erasing cache part, my phone had the boot menu on screen with no response from the controls. Also, a little green status bar was at 90%. (Second thought, that may be battery level. not sure. Confirm?)
Yeah, so, can't get step1 to work.
EDIT: ok. got step 1 and 2 to work. I basically just kept trying over and over and it went through.
So, i got to the custom boot menu. But i try to install update.zip from sd. But i get an error.
It says.
Installation aborted.
--wiping data...
formatting data...
formatting cache...
data wipe complete.
--install from sdcard
finding update package
opening update packing verifying update package.
E: failed to open /sdcard/update.
zip (No such file or directory)
E:signature verification failed
installation aborted.
So, wtf did i do wrong? now my phone is completely wiped, so.... now what?

i think it seems that my computer is not recognising the phone as an android device, cos everytime i connect it, win7 seems to automatically install drivers (nd i cant stop that) and recognises it as HTC ANdroid Device (it appears as a "Disk Drive")..... tried to use htc sync, phone keeps searching nd it fails.. help please i cant use my phone

You should install the old version of HTC Sync until you're rooted, have you done that?

You need HTCsync 2 only for step2, to step1 you need the most updated HTCsync.
And you need step1, don't ignore that step just because it's not working.
Install the latest HTCsync, connect your phone to the computer, and put the phone on fastboot mode (should be written "fastboot usb" on phone)
now on the computer, in the folder of the rooting tools, write:
fastboot-windows.exe devices
Does it recognize your phone? (Should output details bout the phone including serial I think)

wel ive done step 1 now. i created a thread for this here..
http://forum.xda-developers.com/showthread.php?t=1095017
step 1 worked without htc sync, computer is good wen phone is in fastboot, it recognises it straight away, but wen i got into recovery is wher it messes up still even with htc sync. sum1 suggested another way, hav a look at the link, but im gettin signature verification failed or sumthin like that

[Q] Problem Rooting LG Optimus 2x

Hi all,
So I've tried lots of forums on here about how to root my LG Optimus 2x but keep running into the same problem. Here are the steps I've been following:
Remove the battery.
Plug in your USB cable to your PC.
Hold Volume Up and Volume Down at the same time keeping them held down.
Plug in the USB cable to your phone. (Keep the buttons held until Windows detects a new APX device.)
Open Device Manager in Windows and you should see "APX Device" listed with an error icon.
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: One-Click-G2x-recovery-flasher-09-23\APX.
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.
I'm on a Windows 7 32 bit PC. When I check for an APX device in the Device manager I don't see one?
I do see an unknown device but when I try to click have disk etc for this, it does not recognise the drivers I'm pointing at and does not install. Can anyone help me with this?
Many thanks,
Derek

What version are you on? Froyo or Gingerbread? It seems you are flashing CWM but that's a longer way to root. You could always try Super one click, which works on froyo.

Yes, I am on 2.2. So Superoneclick is safe to use?

Absolutely. I used it when I was on froyo. Do you have any sensitive data however on your phone? Just in case you mess up, it's always good to have a backup of it. Probably hook up your USB cable to your pc/laptop and copy/paste the files to be safe.

Ok, thanks. So I have rooted the phone using SuperOneClick. Can you send me a link where I can find information about how to put on Gingerbread 2.3 now? Or maybe there is a better ROM I can use that that? Any advice would be appreicated.
Thanks,
Derek

You can try Cyanogen Mod, but that is experimental, even the RC one (Release Candidate).
You can try other leaked versions of ROMs, or you can download the latest v10L Gingerbread release. Before installing any ROM, I recommend doing a CWM or Nandroid backup.
The link to download gingerbread (it's only out in a few countries in Europe) is located in the development sub section of the LG 2x forums. However, try using the update tool and see if it tells you that you have an update.

I seem to have a bit of a problem. I took your advice and found a forum that helped me to do a Nandroid Backup. As part of the steps it asked me to install ROM manager from the Market. I started this and chose my phone model. I started the Flash ClockworkMod Recovery’ in the ROM manager but it stopped and said a permissions error occured. Then I tried to open other programs but they wouldn't open. I tried to reboot the phone but now it just flashes on the LG logo and won't boot up. Please help me with this.

Hello people on this great forum i am new here so i salud you all.
i installed Cyanogenmod 2.3.4 android on lg optimus 2x butt here is the thing how do you update to a newer version or do you have to unstall everything and start from scratch.any tips are welcome and is there a new version of cyanogenmod

[Solved] Choose zip from sdcard. No files found.

Hi everybody I`d appreciate a lot if you provide me with any sort of help. The problem is following: while I was flashing a new rom my phone went out of power. After reboot I received a continuous loop of boot screen=>install screen=>reboot. In recovery mode when I try to choose the rom`s zip file I have no options. It says "No files found". I tried to mount sdcard and as far as I can see there was no failures. However, mounting emmc results in error. Equally, I tried to connect via Odin, but it does not recognize the device. Please,help me to get at least to the flashing point.

just mount phone under USB storage and copy the ROM files to the SD card that can be read by your phone and Flash the ROM from that location in CWM . To fix USB connections problems, read this
Check this out! You , YES! you are an " Android ". Not your phone but U.​

Thank you for the quick answer. I tried to mount it under USB storage however my computer did not recognize the phone. Following your advice I started to check the connection. The main obstacle was indeed in that Odin was not able to recognize the device under Windows 8.1. After installation of Samsung USB Driver v.1.5.25.0-retail I managed to re-flash my device smoothly.

The main obstacle was indeed in that Odin was not able to recognize the device under Windows 8.1. After installation of Samsung USB Driver v.1.5.25.0-retail I managed to re-flash my device smoothly.

Samsung Galaxy Ace GT-S5830: Unknown USB Device (Device Failed Enumeration)

Hello, I am sorry if this post has already been made somewhere but I still can't find the answer for fixing the problem suggested in the title and I may have posted this on a wrong section earlier, very sorry
So I have a GT-S5830 Galaxy Ace and decided to install CyanogenMod 7 with CWM. The flashing of the phone was a success but I came across a bug (or problem?) of screen orienteering and I couldn't find that answer. Right after this, I then decide to restore back to stock ROM. However, I came across a problem when connecting the device (in Download Mode) to my PC; it stated Unknown USB Device (Device Failed Enumeration) in Device Manager.
Following Procedures I have done:
- USB Debugging enabled on phone
- Samsung USB Driver installed
- All drivers on PC up-to-date
I am also following a guide to restore back to ROM using Odin Multi Downloader, but it does not recognize the phone in ID:COM. The bleep on the PC can be heard but it only recognizes when the phone is in normal mode; in Download Mode it shows Unknown USB Device (Device Failed Enumeration). Please help as I am giving this phone to my sibling.
Thank you.

I'm not an expert by any means, in fact just starting out, but I think you could load the recovery kernel onto your SD card and then boot in recovery mode, select 'load from SD card' (or something similar), select the file on your SD and do it that way. Try looking at wiki . cyanogenmod . org/w/Install_CM_for_cooper (take the spaces out of this URL). You may also need the ADB, I'm not sure, but the details are in that link.
Hope this helps!
