NEW - 3 May 2011 - Simplified Guide to Root & install version 1.2 of Custom Thunderg Recovery by AmonRa/modified by Drellisdee on LG P500
ALWAYS MAKE A BACKUP BEFORE CUSTOMISING YOUR PHONE.
[CUSTOMISING A PHONE USUALLY INVOLVES: ROOTING >>>> INSTALLING CUSTOM RECOVERY >>>> INSTALLING CUSTOM ROM]
The instructions written below have been tested by me using an Indian unbranded GSM model of LG P500 which came with stock Android 2.2.1 (V10C). The procedure to be followed for any LG P500 phone is the same.
This post is split into 4 major sections -
1. INSTRUCTIONS FOR ROOTING
2. INSTALLING ANDROID SDK ON A WINDOWS PC (This step is needed to install Custom Recovery on phone using adb from PC. Can be omitted if Recovery is installed from phone using Terminal Emulator)
3. INSTALLING A CUSTOM RECOVERY
4. INSTALLING CUSTOM ROMs
MUST READ: If you haven't read this thread already, please do read it - Dictionary for n00b - What is.../What does ...mean?
---------------------------------------------------------------------------------------------
1. INSTRUCTIONS FOR ROOTING
To know your present firmware version - Go to Settings/About Phone
Only phones which come with stock android 2.2 could be rooted till recently.
UPDATE - 24 April 2011 : A tool called 'GingerBreak APK' is able to root phones running stock android 2.2, 2.2.1 & 2.2.2. Read about it HERE. This tool enables rooting without the need for downgrading the firmware to 2.2. If 'GingerBreak APK' doesn't work out for you, continue reading to understand the procedure to root your phone after downgrading your firmware. Note: 'GingerBreak APK' permanently roots your phone. Also,GingerBreak might not install BusyBox and SuperUser apps properly on your phone. These apps are required by many rooted apps for their proper functioning. So, use Root Checker from android market to verify the proper installation of these 2 apps.
If your phone runs stock android 2.2, enable 'USB Debugging' on Phone (Settings/Applications/Development). Install z4root (copy the apk file to the sd card and open the file after browsing to the location using the phone's file manager), run it and root the phone. Find it HERE.
Choose the permanent root option as it is still possible to force unroot if needed.
Restart the phone and launch z4root to check the root status. A successful rooting should show 'Unroot' option when z4root app is opened.
{Note: z4root automatically installs Busybox and Superuser application(which appears as an icon in your app drawer) on the phone.}
If rooting fails with z4root, there is another application called SuperOneClick which can root your phone. Read about it HERE
For phones that came with stock 2.2.1 or 2.2.2 installed, rooting first involves downgrading the firmware to 2.2.
Downgrading the firmware can be done with KDZ-FW-UPD.exe (procedure outlined below)
(KDZ-FW-UPD.exe has been claimed to work best with windows xp 32bit.)
FIRST: DOWNLOAD THE Android 2.2 FIRMWARE FOR YOUR DEVICE. For this, go to: [ROMS] Original LG Firmware list and read about the procedure to download the original firmware.
{Tips: Use Ctrl+F in browser to search for Country name, Remember to change the alphabet in 2 places in the final link to download the firmware, Do not bother about the 'CDMA' tag attached to country code. It works for the GSM model phones too. If the link to find out the country codes doesn't work, use the 2nd method mentioned in the post to find out the country code using your phone's IMEI or ESN number }
Download the required Firmware onto your PC.
Links to Original firmware versions for Indian P500 are mentioned in THIS POST
Procedure to install original firmware using KDZ-FW-UPD.exe ( KDZ FIRMWARE UPDATER ) This procedure can also be used to restore the stock firmware and recovery onto your phone in case you want to give your phone to the service centre during warranty period as the phone will appear similar to as you bought it from the store.
[Note: This procedure was used to install V10B_00.kdz(android2.2) over V10C_00.kdz(android2.2.1) on an unbranded Indian GSM model of LG P500 using a Windows 7 Ultimate 64bit updated to date PC.]
1. Install LG PC Suite IV from SD card which came with phone by connecting the phone to PC through USB cable. This is done to install the drivers for the phone on the PC (the procedure is as follows)
- Enable the 'USB Mass Storage Only' mode in the phone's Settings/SDcard & Phone Storage menu.
- Connect phone to PC with the USB Cable.
- Press the 'Turn on USB Storage' button which appears on phone.
- Browse to the folder containing the 'LG PC Suite IV' on the phone's SD card using Windows Explorer and run the LG Installer file. PC Suite will now install on your system along with the required drivers for your phone.
- Cancel setting up PC Suite or continue setting up PC Suite if you want to Sync or backup the phone data.
- After closing PC Suite, Safely remove the USB device from your system.
- Press the 'Turn off USB Storage' button on phone screen.
- Detach the USB Cable.
- Disable the 'USB Mass Storage Only' mode in the phone's Settings/SDcard &Phone Storage menu.
Alternatively, I also tried installing the latest drivers via LG Mobile Support Tool from LG's website (available HERE) but KDZ-FW-UPD.exe (mentioned below) crashes when run. This could be happening only to me, so please try for yourself before writing off this method.
2. For my comfort more than anything else, I switched off the screensaver and other power saving features on the PC and also set the screen timeout delay on the phone to 30 minutes.(Settings/Display/Screen Timeout)
3. Charge the phone to the maximum.
4. Enable USB Debugging on Phone (Settings/Applications/Development).
5. Detach all other peripherals from your PC. Exit all running applications on your PC especially other PC suites if any. Also exit running programs from the notification bar on the desktop. (Also uninstall Nokia or other phone drivers & microsoft visual ++ runtime environments - not an essential step.)
6. Disable 'LGE Virtual Modem' in PC's Device Manager. (In your Windows operating system, go to Control Panel > System > Hardware > Device Manager > Modems > Right click on LGE Virtual Modem and click Disable.)
7. Unmount the SD card from the phone (Settings/SDcard & Phone Storage).
8. Open phone back and remove the SD Card.
9. Download KDZ_FW_UPD_EN.7z onto your PC and extract it to a folder. Available HERE.Direct Download Link. (MD5 of 7zip file - 813A28BE9182AB604A1D43E745CE7AD7)
10. Run the msxml.msi file and complete the installation.
11. Connect the phone to PC with USB Cable.( If you are using a desktop PC, make sure you use USB ports that are in the back of your PC, avoid the front ports.)
12. Run KDZ_FW_UPD.exe from the extracted folder.
13. Chose TYPE as 3GQCT & Phone Mode as DIAG.
14. In the 'KDZ file' space, browse for the firmware you want to install. (In this case V10B_00.kdz)
15. Press the 'Launch software update' button.
16. The firmware flashing process is now underway.
If all goes well, in 5-10 minutes the phone will be flashed with the new firmware.
I shall describe in detail what happened with my phone - 10-15 seconds after launching software update on PC, my phone screen turned blank and in a couple of seconds the phone entered the 'Emergency Mode'. During this mode the screen was yellow with Emergency Mode written along the middle of the screen. The phone stayed in the same way till the Software update procedure finished on the pc and the phone turned blank. I waited a while for it to reboot but after a minute or so, I manually switched on the phone. The phone came alive and following the LG boot animation, the android logo screen came up. The phone spent about 2 whole minutes in that state before booting up fully and entering the home screen. Update: Wait till phone reboots by itself or wait for a while before manually switching it on.
17. After booting up fully, detach the phone from the pc.
(If the phone gets stuck in the android boot logo screen during first boot, doing a hard reset by pressing and holding the VolDown+Home+Power buttons may resolve the problem.)
Go to 'About Phone' in Settings and confirm the change from 2.2.1 or 2.2.2 to 2.2.
Root the phone using z4root as mentioned before.
If rooting fails with z4root, there is another application called SuperOneClick which can root your phone. Read about it HERE
IN CASE OF PROBLEMS DURING DOWNGRADING FIRMWARE, read the following thread completely. Various types of errors and various measures to correct them including some innovative ones like shaking the phone etc. are mentioned here - [HOWTO] Phone not responding at all - last chance to repair. It is advisable to read this thread completely before attempting to downgrade the firmware using KDZ_FW_UPD.exe to become aware of all the possible problems you might encounter and their possible solutions.
PS: Here is the link to the phone drivers that came with my SD card. One user reported a problem wherein kdz updater would recognise the phone but the update process would fail during kdz unpacking. the problem was resolved by using the drivers i sent him. So, if anyone has the same issue, it might be worthwhile to try out the following drivers. I wouldn't advise everyone to follow this method, but those of you who are feeling lucky might try it out.

---------------------------------------------------------------------------------------------
2. INSTALLING ANDROID SDK ON YOUR WINDOWS PC
This step is required to install Custom Recovery on your phone using adb from your PC. Using a Custom Recovery, you can make a backup of your current ROM, restore backups, create partitions on your SD card, wipe your phone and the SD card and then also go on to install Custom ROMs using the Flash from Zip option.
Installing a Custom Recovery can also be done in other ways. Using Android SDK from your PC is just one method.
(Custom Recovery can alternatively be installed on your rooted phone using the commands given in the next section using a Terminal Emulator. This method removes the need for installing Android SDK on your PC and connecting your phone to PC. Download Terminal Emulator from Android Market. Install on phone. Run it and give it root permissions when prompted by the 'Superuser' application. As mentioned in the next section, copy the 2 files (flash_image & the custom recovery image file) needed to install Custom Recovery onto the root directory of SD card. Reboot phone. Open terminal emulator and type 'su' without the quotes and press Enter. This will take you to the root shell (#) from the default user shell($). Carefully type in the 7 commands mentioned in the next section one after the other. After typing in the last command (reboot recovery) and pressing enter, WAIT. The phone will reboot. Custom Recovery will have been succesfully installed on your device.
Hint: Copy the installation commands as a text file to phone & copy and paste the commands one by one into terminal emulator using a text editor. Please make the necessary changes to the installation commands depending on the recovery version used)
To install Android SDK on PC, there are a few requirements/downloads which have to be completed first:
JDK (Java Development Kit) - Download Here
JRE (Java Runtime Environment) - Download Here
Android SDK installer - Download here
So after all the downloads are completed, you are good to go. Run PC as Administrator.
First of all install the JDK, then the JRE and then the SDK Installer.
{If when android sdk installer is run, you get an error that JDK or JRE is not detected even after their installation, wait for a while, shut down the computer and restart and run the SDK installer once again.}
Make sure that while installing the android sdk, the installation directory should be the root of a partition i.e. it should be in the following form: C:\android-sdk, where you should replace the letter C with the letter you have assigned to the partition that you want to install it in.
Now that the Android-SDK is installed, go to the installation directory and start the SDK Manager. You need to add the components of the Android SDK to your installation. Before that I would like to inform you that you can save time if you download only what is necessary. If you are on Android 2.1 then you should download the 2.1 sdk, for 2.2 the 2.2 sdk and so on. You do not need to have all the versions for this thing to work. Just your version would do. So to start adding components, I recommend that you read THIS
After installing the desired components, you need to do perform some simple steps in order to use the adb terminal just like the cmd terminal for Windows.
For that purpose, here are the steps to be followed:
Right click My Computer, select Properties, and click Advanced System Settings. (Windows XP users - Right click My computer and just click Properties and select the Advanced Tab)
Click on Environment Variables, in the System Variables box, scroll down to the variable name 'Path' and double click to edit it
It would read something like " %SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\ATI Technologies\ATI.ACE\Core-Static".
Here you need to add a semicolon ( ; ) and add the path of the tools folder in android-sdk.
It should finally be like this " %SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\ATI Technologies\ATI.ACE\Core-Static;C:\android-sdk\platform-tools {or the location where adb.exe resides on your system}
Click OK wherever asked and then restart your computer.
Now open a command prompt window and type adb and hit enter. If a terminal window is displayed, you have done it all right.
If it gives some error message, read the article carefully and see what you have messed up with.
---------------------------------------------------------------------------------------------
Tip:
Using adb - How to install apps from PC without having to copy them first to the SD card?
If you want to install apps in one click, all you need to do is download the .apk file of your application to your PC and set the open with option to this batch file which you can download HERE
Save the batch file on the desktop of your PC before setting the option to 'Open With'.
---------------------------------------------------------------------------------------------
3. INSTALLING A CUSTOM RECOVERY
(Procedure of installing Custom Recovery using a terminal emulator from your phone instead of installing android SDK on your PC and connecting your phone to PC is mentioned in the last section.)
UPDATE - 3 May 2011 : Very simple way of installing Custom Thunderg Recovery by AmonRa/modified by Drellisdee version 1.2. Originally posted by ungaze in this post.
1. Download Android Terminal Emulator from Android Market. Install it on your rooted phone.
2. Download the file "amon_ra_recovery_installer.zip" from here or here. Check the MD5 hash value of the downloaded 'zip' file using tools like HashTab etc. before proceeding further. Correct MD5 value : 86db8a52b01f049cadb8f097a4c5bd9e
3. Extract the contents of the 'zip' file to the root of the sd card (ie. not inside any folder) using tools like 7-Zip or WinRAR or any other similar tool.
4. Open the terminal emulator app on your phone and type in the command 'su' without the qoutes. This will prompt a popup on your phone from the SuperUser app asking you whether you want to give root permissions to the terminal emulator app. Click 'Allow' and proceed. You will notice that the shell prompt has changed from the previous user shell '$' to root shell '#' in the emulator app.
5. While in the root shell '#', type in the following command and press Enter. Wait and the phone will reboot into the Custom Recovery.
Code:
sh /sdcard/rf.sh
Once you are up and running with a rooted phone, you will need to download the 2 files needed to install the Custom Recovery. They are:
Download No:1: flash_image - (This file is the same one needed to install any of the 3 versions of Custom Thunderg Recovery by Drellisdee given below)
Download Link (MD5 of zip file - 13FED5DF927214D744A256DAB4C3DC06)
Mirror Link (MD5 of zip file - 13FED5DF927214D744A256DAB4C3DC06)
Mirror Link - requires registration at androidforums.com. (MD5 of zip file - 13FED5DF927214D744A256DAB4C3DC06)
Download No:2: Custom Recovery image file - Choose & download any version among the 3 available after reading what is written below.
Custom Thunderg Recovery by Drellisdee has versions 1.1, 1.2 and 1.2.1 at the time of writing this. I personally prefer version 1.2 as it supports backup & restoration of ext4 Partition on SD Card. Version 1.2.1 is a little experimental in nature & it may not fit all devices as it has a size near 5 MB.
Link to xda-forum thread for Custom Recovery P500/Thunderg - HERE.
The different versions of the Custom Recovery image files are available at the following pages
Custom Recovery P500/Thunderg v1.1
Direct Download link - (MD5 of zip file - eb4ea2ffb26f387a891bb4d7261a0e5f)
Mirror Link - (MD5 of zip file - eb4ea2ffb26f387a891bb4d7261a0e5f)
Custom Recovery P500/Thunderg v1.2
Direct Download link - (MD5 of zip file - 217FC9115899A41195CF124CAF07B880)
Custom Recovery P500/Thunderg v1.2.1
Direct Download link - (MD5 of zip file - 388aac16b1184ab15b5500b2b32d914c)
Please check the MD5 hash values of downloaded files to ensure that files are not corrupted using tools like HashTab etc.
Now to install Custom Recovery, Copy the two files [ the chosen recovery image file (*.img) & the flash_image file (flash_image) ] and paste in the root of your SD card (root means the directory L:\ where L is the letter for your Phone's USB Storage. In short, don't create a folder and paste the files inside it on your SD card).
{Note that the recovery image file should have an .img extension and flash_image file should have no extension when placed on the SD card}
Reboot the phone. Connect phone to PC.
The next step requires Android SDK to be installed on your PC.If you have installed the Android SDK, follow these steps:
Go to Start Menu & Run and type cmd (run as Administrator)
In the cmd window, type adb. If you have installed it correctly, you will see a lot of text on the screen. If you get an error message then you have probably not installed the Android SDK properly.
Type adb shell and hit enter
Type su and hit enter
See your phone at this time and touch the 'Allow' option which SuperUser shows you
Now the terminal window will have a # sign appended to it instead of the previous $ sign. See this screenshot for a better understanding
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Now one by one, copy the following lines, in the serial order and paste it into the terminal window and press enter following each line(right click on window and paste, CTRL + V won't work)
mount -o remount,rw -t yaffs2 /dev/block/mtdblock1 /system
cat /sdcard/flash_image > /system/bin/flash_image
chmod 755 /system/bin/flash_image
mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak (if it gives error message here, simply proceed to the next step)
mount -o remount,ro -t yaffs2 /dev/block/mtdblock1 /system
flash_image recovery /sdcard/LGp500-recovery-v12.img (If the recovery version chosen is different from v1.2, type the appropriate file name of the recovery image here instead.)
reboot recovery
Click to expand...
Click to collapse
Wait. The phone will reboot now.
Note:{If you get this error after step 4
mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak
failed on '/system/etc/install-recovery.sh' - No such file or directory
Simply move on to the next step.
If you get any errors other that those mentioned here, please do not proceed with the last command of 'reboot recovery'. If you do so, recovery may not be correctly installed and you will lose all data on the phone as the phone will be reset to factory defaults. Please go back to the instructions and see what you have done wrong.
NOTE: If on booting into the recovery you get the following message at the bottom of the screen -
E: 'Bad Boot Message'
Don't panic, it's perfectly normal and you can proceed with what you want to do from the recovery.}
Detach the phone from the PC.
To access the Custom Recovery, turn off the phone and then press & hold Home+Vol Down+Power buttons to boot into the Custom Recovery.
---------------------------------------------------------------------------------------------
Once you have booted into the recovery, the touch screen won't work. The actions assigned to the different buttons are given here. Use them to navigate through the different options in Custom Recovery.
Up & down: vol-up and vol-down key
Select: Menu key (left most)
Back: Back (3rd from left)
---------------------------------------------------------------------------------------------
What does Custom Recovery look like & What does it do?
Note: In Custom Recovery versions 1.2 and above, zips can be extracted from inside folders. So, save the zips in a folder named AAA and flash the zip after browsing inside the folder through recovery. The folder name should be named 'AAA' so that it appears among the first on the recovery screen, since scrolling is not an option in recovery.
Note: There is also an unofficial port of ClockworkMod Recovery availble. I do not recommend this recovery for newbies as it isn't compatible with all Custom ROM's out there.
---------------------------------------------------------------------------------------------
4. INSTALLING CUSTOM ROMs
BEFORE FLASHING ANY ROM, DO A NANDROID BACKUP FROM CUSTOM RECOVERY
Since all the ROMs have their own kinds of partitions to be created and other requirements, you can check them at the ROM specific pages.
General procedure to follow for installing a Custom ROM
Boot into Custom Recovery
Wipe your cache, dalvik cache, SD card
Make partitions according to the ROM requirement
Wipe cache again.
Connect Phone to PC
Toggle USB MS and paste the ROM zip file to a folder called AAA in the root of the SD card
Disable USB MS.
Detach phone from PC.
Select 'Flash from zip' option in Custom Recovery menu
Select the ROM file
Flash the ROM file
After flashing is finished, Reboot the phone.
Note: It will take some time to flash and reboot into your new Custom ROM. The phone may stay with the boot logo displayed for a number of minutes. Do not switch off phone during this period.

The procedure for downgrading the firmware is included in the article. The procedure is the same for installing any version of original firmware on the phone.
Procedure to change from one custom rom to another various with each rom.some may need a wipe while others might need repartitioning your sd card.

Yes. It worked fine before. I tried to flash with CM7, and something went wrong. The whole SD-card is empty, works on another phone though. However, Windows will not recognize it no matter what I do

Do you mean to say that your sd card is empty our that you can't see the sd card contents on your computer?

Both. I put the memory card on another phone and it said it was empty. Also, custom recovery says it's empty and from mount menu, I can see it keeps unmounting.

Have you tried another card on your phone?

I managed to get the card work via another card reader. I put the zip files on it and trying again now. Hope it will work.
EDIT: It works!!!

nvm.....................

Glad to hear it.

Sorry for noob question, but after downgrade to 2.2, root, can I flash any rooted 2.2.1 ? And is there any?

Once you have rooted your phone, you can install any custom rom meant for p500. This includes all android versions. And, you don't have to apologise for being a noob, this thread is meant for noobs primarily. everyone has to start someplace. There are many rom's accessible on this forum including android versions 2.2 to 2.3.3. I suggest you try Nessy#Euridice ROM by Dookmatt. I am using it and it is easy to set up.it is based on android 2.2.2

Thanks,
So if there isn't any method for root on 2.2.1, how they managed to give us pre rooted 2.2.1 roms?
I seek the fastest and stable rom with OC, but Im used to CM7 tweaks,.so im interested in it the most. So is it usable? Beside cm7 which is the fastest?

Guess, you will have to ask the people who make the rom's. I don't know about the cm7 rom.haven't used it myself.

rooting a stock Rom is hard where as as rooting a custom made rom is easy because u only need the framework to create ur custom rom....
and about CM7 u can choose between many flavours.... its upto u ..

But GinderBreak can root the IncS, but somthimes you need some "Ninja" tricks.

Are you done?

This just worked for me - it was simple in the end!
I used a spare SD card (I don't think I needed to), just copy/pasted the clockwork recovery .zip file to the card (not in a folder on the card) and rebooted, holding volume down on start-up. After that, it automatically prompted me to install the file, so I let it install.
Then, I rebooted the phone and deleted the above file from the SD card, and replaced it with the signed root .zip file and rebooted with the volume down button again.
Just follow the steps, one by one, 'To root:' in the above linked post, after you have installed the recovery file - it worked first time for me and was actually simple to follow!!
My phone works as it always has done (as you would expect/hope), but now I have root - confirmed with Root Explorer app from Market.
Thanks to all involved in the linked post above.
I also tried GingerBreak a few times but it just didn't work for me, so I gave this a go and it worked first time.

I dont quite understand step 4, 5, 6:
4. Extract recovery.img from the archive and put it with fastboot.
5. Put the phone is Fastboot USB mode (HINT: Android is not up and running - access it from your hboot screen - see how below)
6. fastboot flash recovery <recovery.img> <<< from a command line (use root for Linux- sudo ./fastboot yadda)
Step 4, it says put it with fastboot, does it mean after i extracted the recovery.img, move it to the same folder with the fastboot app (i.e. to the folder android-win-tools where the fastboot app is located?).
Step 5, Fastboot USB mode, this is done by holding the volume down button and the pressing the power button, when the white screen comes up, select Fastboot, and then plug the phone back to the computer via USB?
Step 6, after the phone is plugged to the computer via USB, double click on the fastboot app (the one inside the android-win-tools folder) and when the black prompt screen comes up, type in Linux- sudo ./fastboot yadda?
Btw, I am on Windows computer, not Linux, so is the command prompt Linux- sudo ./fastboot yadda correct?
Also, if I want to bluetooth the su-2.3.6.1-ef-signed.zip to the phone, will it go directly to the SD root location? If not, when I do clockworkmod recovery and "install zip from sdcard", will it able to locate the file?

No, follow step 6 you use command line like this: "fastboot flash recovery C:\recovery.img". After you choose "install zip from sdcard" you have to choose the location where you put the file you want to install.

So this is exactly how it should be typed in the command prompt?
fastboot flash recovery C:\recovery.img
Are the rest of other steps correct?

I am still getting stuck at the Clockworkmod installation part, without this I cannot get to the root step.
I extracted the android-win-tools.zip, which contains the following files:
adb
AdbWinApi.dll
AdbWinUsbApi.dll
android-info
fastboot
and then extracted the cwm-vivow-4.0.0.4-recovery.img.zip, contains the following:
recovery.img
then I moved all the above 6 files directly to the C: directory. After that went into cmd and typed the prompt exactly like following:
fastboot flash recovery C:\recovery.img
Did I miss anything? Because after typing that line and hit return it came out nothing. Is that prompt correct?

Why not root with superoneclick -> download clockworkmod from market and install recovery from app? Work perfectly for me...

clockworkmod from market, is it aka ROM Manager?
This app won't work because it requires a ROOT phone, which is what I am trying to do.

Yes, and before use superoneclick.

Superoneclick is not from market, use google. Its for rooting.

You can also try Gingerbreak if you can't get SuperOneClick to work (again you'll have to search for this as it's not in the market).

Just installed SuperOneClick and clicked Root, it said the phone is rooted successfully. Then clicked on the "allow non market apps" and the result said non-market apps enabled.
But then I went to market and installed a screen cap app (one needs root), launched the app and it said Root required - Your phone does not appear to be rooted or has not been given root privileges.
Did the SuperOneClick really root it?

[Possible solution]
Instead of safely remove on PC, use 'Disconnect' option from CWM recovery
If you have already used 'Safely remove' option from PC then,
In terminal issue following commands
Code:
[SIZE=2]adb shell[/SIZE][SIZE=2]
# echo 0 > /sys/class/usb_composite/usb_mass_storage/enable[/SIZE][SIZE=2]
# echo 1 > /sys/class/usb_composite/usb_mass_storage/enable[/SIZE]

[Acknowledgement]
tj_style because this CWM recovery is an update to his CWM_recovery_fib0_v2
DooMLoRD for helping me out with my doubts and for familiarizing me with the development
All of you who will test it and give me feedback.

Extra info
Few advantages that I can think of for having
[ADB support in recovery]
As in recovery mode you get SU access, whether your phone is rooted or not, you can issue root level commands like mount, chmod, chown, fdisk
You can read, write to, move, modify, replace any system files (at your own risk)
Many more possible features which you can find by exploring this forum.
[USB support in recovery]
If you are playing with trying out new boot.img, boot-animation.img, splash.img which you are developing side by side, this will prevent all the hassle for rebooting phone just for adding new updated files to sd card (that you have just created)
Though you can use adb push feature in recovery, but I prefer copy / paste using computer as it checks for complete file transfer before ejecting the drive

hi
thanks adding CWM to this phone is the easiest i have done it was real pain doing it on my other phones
now my question is i have added CWM and i have taken a nand back up of the original Stock rom if i wana go back to the orignal for some warranty purpose in the future
if i do this is it ok
1.do a nand restore with CWM
2.go to down load mode & replace the CWM recovery with the original phones recovery which i have saved on my PC
is this good enough just in case i need to give phone to service for warranty purpose

Yes, that will surely do!
Also, as paarkhi has suggested you could also flash original Spice Gingerbread Update file ("nb0" file) using SUTL, since "nb0" files have all original files (bootanimation.zip, recovery.img, boot.img-which includes original kernel) and your phone is already registered for Spice Gingerbread upgrade.
[Though this is single step - easy option but it requires PC, I have one more option which you could use if your on the go and PC is not accessible]
I have posted steps to restore stock recovery at Restoring Recovery - An easy way (CWM / Stock)
and then you can flash any original "nb0" file.

Hmm... if you knew exactly which apps you deleted, you might be able to find them in another ROM and just adb push them back to the tab.
Otherwise, at this point, I would suggest a re-stock (take the tab back to factory settings via re-flash).
Which tab do you have exactly, and what Android OS were you running? For example, I have a Galaxy Tab 7" P1000 GSM (T-Mobile) and I used to run Gingerbread (2.3.3)

thanks
mine is a Galaxy Tab 7" P1000 GSM (ORANGE) on Gingerbread (2.3.3)
I know I uninstalled z4root but honestly cant recall what else.
How easy is it to restore?
Not sure how I reflash it?

Hmm, I'm not too sure if you need root or not to do an adb push, but it's pretty much:
Download app to computer, plug tab to pc, open cmd and do adb push FILE.apk
You'd need android SDK though prior to that and platform tools.
As for re-stocking, you can either use Odin (samsung's phone/tab flashing tool) or Heimdall (open-source flashing tool). In any case though, Team Overcome made a nice guide for restocking that should work with Odin.
http://forum.xda-developers.com/showthread.php?t=1317384
In short, you want to have Samsung's drivers installed, reboot your tab and put it in download mode, download the files needed to re-stock from that thread, open Odin, enter the gt-p1000 pit for pit, GB-stock-safe-v5.tar for the pda, and a modem for modem, then start flashing
I also made a nice guide involving Heimdall re-stocking here: http://forum.xda-developers.com/showthread.php?t=1508703

wow
bit too complicated for me I am afraid.
I am grateful for your reply, but I could not do that.
Looks like my TAB is useless now

It's not really too hard I'd hate to see your tab useless though.
If you had some sort of instant messenging service, I could maybe guide you through the process

thanks but I do not use Instant messaging.
@yyalanyy on twitter is all, but doubt tht could help?
If you could email me any simple [and I mean simple] help to [email protected]ltrans.co.uk I would be very grateful.

I can make you a package zip that will pretty much only require you to install drivers and then run 1 file (I can give you a small walkthrough on how to setup the drivers in email)
It'll take me a little bit to upload it though (I would say 40mins :/). Otherwise, if someone else feels like offering some simple instructions, feel free to do so

That would be great
many many thanks

Actually, download this: http://www.rosanoscorner.com/p1000/downloads/GB-Stock-Safe-v5.zip
And i'll upload my batch file in a bit. You'll just have to extract some things though
---------- Post added at 12:35 AM ---------- Previous post was at 12:16 AM ----------
Here's a guide (it's a bit long, but the steps are really quick)
- You'll also want 7zip installed (WinRAR might also work if it can open .tar), it's a free program for unzipping archives
1. Download that .zip file above and unzip somewhere
2. Download my archive here and unzip somewhere: http://www.mediafire.com/?pdpy59z6bdej6wb
3. In my folder, there is a Drivers folder, go in it
4. Run SAMSUNG_USB_Driver_for_Mobile_Phones (if it says drivers are already installed, then close it)
5. Reboot tab into Download Mode (shut it off and unplug from charger/computer, hold Vol-Down button and power)
6. Plug tab into computer
7. Go to the Drivers folder in my folder and open zadig
8. Options > List All Devices
9. Select Samsung USB Composite Device

10. Hit Install Driver (accept any prompts you see about unsigned drivers)
11. If it's successful, close it
12. Unplug tab and plug it back into computer (on the same USB port)
13. Go to the folder you extracted GB-Stock-Safe-v5.zip at
14. Find the folder called JPZ Modem (for anyone else following this, use the modem of preference)
15. Go into it, take the modem.bin, put it into my folder (my folder with the .bat and heimdall stuff)
16. Go back to the GB stock folder
17. Open GB_Stock_Safe_v5.tar (7-zip should open this like an archive)
18. Drag every file in that .tar to my heimdall folder
19. Run flash.bat in my folder
20. Do not do anything with the tab until it's done
21. Once the tab is done, you should be in recovery. You have to (i think) use the volume buttons to scroll up and down in the menu, but you have to wipe data, and then reboot to system
22. Done
I'll be here if you need any help still

hi
i have followed your instructions. when I run the flash,bat a cmd window opens, tells me to press any key but nothing happens?

Hmm, it should be starting Heimdall and starting a 1-2min flashing process. Not too sure why it wouldn't actually work though
Try running it again and then when it says press any key, Right-click anywhere in command prompt > select all, and then when everything is selected, press Enter. Then copy/paste that into a post here

C:\Users\alan acer\Desktop\helpsamsung\Re-stock (Heimdall)>heimdall flash --repa

its approaching 1.00am here so I must get some sleep.
Thanks for your help
I will have another try tomorrow
Thanks you

Hmm, how many files are in your Heimdall folder and how big is the folder? I think you should have about 15 files in the folder total, equaling 391MB
Edit: Just saw your message about you heading to bed, night

think thats the problem.
After using 7zip on your download there are only 6 files totalling 28mb ?

Hi
Tried it again and it worked!
So pleased thank you for all of your help
Problem now is different as it is now NOT rooted.
and it seems very laggy now.
I have tried Z4 root and it fails
I have tried superone click and that fails at stage 6
Any ides?
Would it be best via ODIN?

Hmm, thought I hit reply earlier but guess not :/
Anyway, with Odin, the only thing that is different is that it automatically wipes data/factory reset and wipes internal SD instead of you having to manually do this. Generally, Odin is slower as well too, but it does work
As for Root, hmm, not too sure what can be done about this. I can't recall me actually rooting Gingerbread (maybe someone else can shed some light on this?) I always flashed a custom ROM right after I re-stock, and most (if not all) custom ROM's offer Root instantly

No worries. At least my tab is useable again now. I would once again like to thank you for the help and time that you have given to me.

How to root your Phab 2 (PB2-650Y)

This is NOT a guide for n00bs. You will need a functional copy of ADB and FASTBOOT (as well as any required Lenovo ADB drivers if you are windows tragic) running on your PC with Debugging enabled prior to proceeding.
This is NOT my original work. All the real credit goes to some guys in Russia as best as I can tell. I merely google translated their work and cooked up my own method for rooting (which is a bit easier than what they recommend). You can find their source materials here: Russian Lenovo Website - Phab 2 Unlocking the bootloader thread.
Grab the latest version of SuperSU from Chainfire (https://download.chainfire.eu/696/supersu/)
Download the version of TWRP I found on the Lenovo Russia website here (it is attached to this post)
Copy SuperSU to your Phab 2's SD Card (it can go on either the internal or an external drive) (ADB push SuperSUxxx.img /sdcard/)
You need to unlock your bootloader if you have not already done so:
Code:
adb reboot bootloader
fastboot oem unlock
Allow your Phab 2 to fully reboot and verify debugging is still enabled and the OEM unlocking option is enabled in Developer options.
Now that we've got a good clean operational unlocked bootloader let's apply our new recovery:
Code:
adb reboot bootloader
fastboot flash recovery TWRP-PB2-650_3.0.2.img
Hold down the power button on your Phab 2 until it powers off.
Press the center of the volume rocker (both vol+ and vol- need to be depressed) and at the same time hold down the power button until your Phab 2 posts. You'll know you did the procedure right because an ASCII arrow symbol will be scrolling through the device's 3 boot options (Recovery / Fastboot / Normal).
Release the power button and roll your finger holding the volume rocker to the volume up side of the rocker. Release the volume button.
Press Vol+ until Recovery is selected (it is the first option)
Press Vol- and wait 20 or so seconds for TWRP to load.
You now have to decide if you want to make TWRP your permanent recovery. If so, mount SYSTEM as RW and using TWRP's Advanced File Explorer navigate to /system and either delete or rename recovery-from-boot.p (I renamed mine to recovery-from-boot.p.save).
Go back to TWRP's main menu and select INSTALL. Navigate to the SuperSU image you copied to storage at the very beginning of this guide and flash it.
When you're done, reboot.
Don't panic when your Phab 2 bootloops once. It'll boot fine on its second pass. In another 20-30 seconds you will be greeted by a fully rooted Phab 2.
Enjoy! Screenshots are attached to the second post.

is this working for phab2 pb2-650m?

I assume so. The original work was based on a 650M but I can only validate my additions on the 650Y since I don't have a 650M

You can find their source materials here: Russian Lenovo Website - Phab 2 Unlocking the bootloader thread.
Grab the latest version of SuperSU from Chainfire (https://download.chainfire.eu/696/supersu/)
Download the version of TWRP I found on the Lenovo Russia website here (it is attached to this post)
Copy SuperSU to your Phab 2's SD Card (it can go on either the internal or an external drive) (ADB push SuperSUxxx.img /sdcard/)
You need to unlock your bootloader if you have not already done so:
Allow your Phab 2 to fully reboot and verify debugging is still enabled and the OEM unlocking option is enabled in Developer options.
Now that we've got a good clean operational unlocked bootloader let's apply our new recovery:
Hold down the power button on your Phab 2 until it powers off.
Press the center of the volume rocker (both vol+ and vol- need to be depressed) and at the same time hold down the power button until your Phab 2 posts. You'll know you did the procedure right because an ASCII arrow symbol will be scrolling through the device's 3 boot options (Recovery / Fastboot / Normal).
Release the power button and roll your finger holding the volume rocker to the volume up side of the rocker. Release the volume button.
Press Vol+ until Recovery is selected (it is the first option)
Press Vol- and wait 20 or so seconds for TWRP to load.
You now have to decide if you want to make TWRP your permanent recovery. If so, mount SYSTEM as RW and using TWRP's Advanced File Explorer navigate to /system and either delete or rename recovery-from-boot.p (I renamed mine to recovery-from-boot.p.save).
Go back to TWRP's main menu and select INSTALL. Navigate to the SuperSU image you copied to storage at the very beginning of this guide and flash it.
When you're done, reboot.
Don't panic when your Phab 2 bootloops once. It'll boot fine on its second pass. In another 20-30 seconds you will be greeted by a fully rooted Phab 2.
Enjoy! Screenshots are attached to the second post.

You should make a video of the procedure. So you are saying after flashing the recovery, have to press power and volume up+down together until phab2 posts. What is posts? Do you mean reboots? And what do you mean by roll the finger?

This is NOT a guide for n00bs. You will need a functional copy of ADB and FASTBOOT (as well as any required Lenovo ADB drivers if you are windows tragic) running on your PC with Debugging enabled prior to proceeding.

Hey thank you for the method. My device is PB2-650m Philippine version. Twrp recovery installed without issue , but after flashing supersu, would not boot. Stuck on second boot. I flashed UPDATE-unSU.zip to unroot and factory reset device. Flashed SuperSu-v2.79 and rooted without issue.

Too bad you didn't make a video...

I did not have time. My phone got stuck on 2nd boot and was trying to figure out way to fix it. I fixed it by deleting supersu and factory resetting. I found different SuperSU version and worked. Thanks to you for providing me and the other phab2 owners with custom recovery.

Anyone get voLTE to work on this phone (PB2-650Y)?
