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. Download Link
---------------------------------------------------------------------------------------------
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 ..
hi
hey man thanks for the wonderful tutorial!!
i just broght my phone 2weeks back. got it after lots of requests to dad!!
i wanna try all the stuff but im damn scared if i would brick my phone..
although i have the exact same phone as yours..unbranded indian optimus one with v10c
should i try it or is there a risk that ill brick it..?
if i brick it.. is there a chance that i can get it repaired? or will the lg ppl refuse to support me because i screwedwith it??
thanks in advance!!
I am seeing a lot of posts with questions about the local.prop file. If any of you are having permission issues enable mass storage mode then open notepad on your computer and type " ro.kernel.qemu=1" then click save as and name it local.prop and save it in the /data folder on the phone. DO NOT wipe data after creating this file or it will be deleted. Then re-enable internet connection mode and USB debugging and proceed with the rooting process.
how bout for us guys in test mode?
You could either push it with adb or copy to the external SD with a card reader then use a file browser to copy it into the /data folder.
is this the correct way?
first flash v7 stock..then root..then make a local.prop..save it..use lgnpst to update to zv8??? then I would still be rooted?

I started a thread earlier today about similar problems. I will try this when I get home tonight and let everyone know the results.
EDIT: Problem with this method is what I mention on my other thread http://forum.xda-developers.com/showthread.php?p=24741989#post24741989
I can't move files into the /data folder because the permission denied error message I get. Oddly enough, I only started getting these weird permission problems after I took the advice from keithmcelhinney (basically saying do the same code but within the terminal emulator.. which I thought I did successfully)
http://forum.xda-developers.com/showthread.php?t=1580571&highlight=ro+kernel+qemu=1
is there a tool or something that can fix permissions without CWM or moving files internally?
If you already have root you can download an app call fileslick to change permissions on the /data folder so you can paste a new local.prop in there. Although I was able to successfully change permissions and copy my local.prop file, I was still unable to get the OTA update to zv8.
Here is a snippet from another post where he is trying to OTA update from vz7 to vz8 while keeping root and reinstalling cwm: http://forum.xda-developers.com/showthread.php?t=1580987
1 - Using LGNPST, push the ZV7 .tot file.
2 - Factory reset, just in case
3 - Using the OLD AIO (Root&RecoveryAIO), root it (option 1 only!).
4 - Use Check Root app to make sure you have root
5 - Use fileslick app to Change folder permissions and move local.prop file app to
- Open fileslick, click actions, and click show root
- Swipe all the way left until you are at root and see /data folder
- Tap the data folder so it has a green check and then hit actions and select "permisions"
- Check everything in that menu (This will make it so you don't has any permission denied menus when moving the local.prop)
- Put the local.prop file from the "data" folder in the ZV7toZV8Root.zip by tapping it in fileslick, navigating back to the "/data" folder you just set permissions for, clicking "actions" and clicking "copy file to this location"
6 - Go to about this phone in the settings app and check for updates to update ZV8
7 - After reboot use ZV8CWMRecovery.bat (option 1) to install clockwork
8 - After reboot go back and use OLD AIO (Root&RecoveryAIO) to reboot to recovery (option 7)
9 - Reboot recovery and wipe data
10 - After wiping data and without exiting CWM, flash BrokenOut.
11 - DON'T WIPE DATA AFTER FLASH
For digital wellbeing reasons* I'd like to lock myself out a handful of websites by redirecting them to local.
I've tried to follow the guideline using Magisk, only to nearly brick my phone (a friend had to flash the original image). What is the easiest way to simply modify the hosts file without changing too much?
lg lngo
I've been using this Magisk module for a long to block Ads. Just edit etc/hosts and install!
That means you recommend to simply follow this guideline and install Magisk including this plugin?
It may be that the websites you are concerned about are blocked in the hostlist that AdAway would install. If your phone is rooted, consider installing AdAway. I think it can only be installed using F-Droid.
@Rafiul Bari Chowdhury: I edited the hosts file in your zipped module, run it in Magisk: worked fine, after restart I saw the changes (shell cat /etc/hosts). However, after locking it again the device is bricked. I'm looking how to flash the factory image again.
Any ideas what went wrong? Is it not possible to edit root files and relock the phone again so it seems "normal"?
Edit: re-unlocked the phone and it works again. Reset OS (and hosts file), but works. When locked again: "Can't find valid operating system". Any ideas?

i doubt the phone is bricked. it is either locked up that you can force off by holding down power + vol up + vol down all 3 at the same time for 15 to 30 seconds to force off. you can get into boot loader by power + vol down. then flash the stock image from https://developers.google.com/android/images#barbet
make sure you have the google usb drivers and use chrome installed or nothing work when trying to flash back to stock.
it pretty hard to mess up the bootloader section of the phone. it can be done but you would have to flash a corrupt image to the boot partition.
i use to use adaway https://github.com/AdAway/AdAway/releases/tag/v5.12.0 if i remember right you can modify the host file using that apk
I did id all over again: Flashed latest firmware (barbet-sp2a.220305.012), installed Magisk acc. to Guideline here in the forum. Same result.
Phone wasn't bricked, Boot loader worked fine all the time, sorry for unprecise description. Editing the hosts file simply doesn't last (maybe I have to change the file on partition A and b??!) and 2nd, if locked again the phone won't find the OS.
Gives me two questions:
1.) how actually does the script from Rafiul Bari Chowdhury work, how can it replace the hosts file while I can't do it manually due to read-only partition.
2.) If I change both partitions, A and B, would the change last after I lock the phone again? Then how do I do it and how do I make sure the OS is found.
Is it even possible to change system files and go back into "locked" mode again without any other impacts?

did you try adb shell then su ? you can try chmod -R 775 or 777 a file to give full permisions. you probably could get away with just 660 for read and write without execute command. so chmod -R 660 (filename) should allow you to change the file permisions and allow you to write to the file.
as for relocking. i usually leave mine unlocked. i think if you relock it does a verification process of the rom. not sure on that one. maybe a developer can answer that question.
Hey I am trying to figure this out. did OP ever find an answer?
For me, I am on a pixel 5 with android 13, a phone I got from Backmarket. It is an "Unlocked" pixel 5. I thought this would make things easier. According to an article, pixel 5 is "one of the easiest phones to root"
:/
The phone is not A/B, only A
I pulled the magisk image using adb to the file with platform tools
I tried sideloading a hosts file through ADB but I got Error 21.
I have tried rooting the phone with Magisk boot.img but it fails because in Fastboot "Remote: failed to write to partition not found" and in FastbootD there is also an error.
SU is not found when I attempt to use the adb shell. It is Greyed out in the Magisk App
I have mounted the /system with Recovery but then I receive "Remote: no such file or directory"
I am using the most current Platform tools.
Any advice? Really I just want to edit the hosts file

Don't do this method...
Once you're rooted with Magisk, open Magisk and go to settings and tap Systemless hosts. This installs the Systemless Hosts module. Then you can just use an app like AdAway (https://f-droid.org/en/packages/org.adaway/) and block the domains you want there.
Very nice to see Y700 get it's own place on XDA! I myself had just bought the 12GB version and have been very satisfied. The tutorials and info related to this model had been very difficult to come by and mostly in other languages, so I had to do my own research and exploration. So far I was able to flash ROM and extract it's boot image for root thanks to the following tutorial (in Japanese)
boot.imgを入手できない機種でMagiskを導入する方法【DSU Loader】
Android端末のカスタマイズやRoot権限の使用が可能となる「Magisk」ですが、一部例外を除き、導入に…
smartasw.com
The boot image extraction part is trickier as Y700's roms come in GSI form. But with a workaround we can still achieve the same goal. (I heard that you can also use QFIL to do that but I haven't been able to make the tool work, so if someone else can make a tutorial that'd be great)
First you need to prepare:
- DSI-Sideloader from https://github.com/VegaBobo/DSU-Sideloader/releases
- Magisk Manager from topjohnwu's GitHub repo
- a GSI ROM with built in root permission. The one the tutorial was using: https://github.com/phhusson/treble_experimentations/releases/tag/v402 --> go download "system-squeak-arm64-ab-vanilla.img.xz" (~600MB, smallest needed to fulfill the task)
- turn on developer mode and ADB debugging. Get Google SDK platform tools ready and USB drivers installed.
Connect your Y700 to a computer. Check if ADB works.
Next, install the DSI-Sideloader app. Also extract the .xz package you downloaded above to get the .img image (should be ~1.7GB in size)
Copy the image to your Y700 tablet. Open the DSI-Sideloader app, load the image, set userdata size to default (2GB). You can leave image size unchanged.
NOTE: if you have an SD card inserted, click on "config" and check "Unmount SD", or just eject your SD card from tray. Failing to do so will result in error in the install step.
After you're done, click "Install". Once finished there will be a pop-up with commands you need to enter in the terminal of your choosing. On your computer navigate to the directory containing executables of Google SDK platform tools, fire up terminal, enter the 1st command (says non-root) as instructed, and run it.
You will see a progress bar in the drop-down notification area which will complete in a moment and prompt you to reboot. Do that from there.
After reboot you will be running the modded Project Treble ROM, with root access. It's a full fledge OS but once you shutdown / reboot you will go back to your own OS. Treat it as a LiveCD of some sort.
While still connected, turn on dev mode + ADB debugging and go back to terminal for some ADB work. Next we will be extracting boot image under the current environment, made possible by it's built-in root permission.
Run the following line by line:
Bash:
adb shell
Bash:
su
Bash:
cd /dev/block/bootdevice/by-name/
Bash:
mkdir /sdcard/backup_img
Bash:
for file in *; do
if [[ "${file}" = boot* ]]; then dd if=/dev/block/bootdevice/by-name/"${file}" of=/sdcard/backup_img/"${file}".img ; else continue ; fi
done
The 4th command creates a new directory storing extracted boot image, in our case /SD card/backup_img; and the 5th command is the meat of the entire process. It consists of 3 lines, key in one at a time and press "Enter". First line is "for...do", second is "if [[..." to "fi", third is just "done".
After some time the extracted boot image will be stored under the directory specified by the 4th command, in our case /sdcard/backup_img . They are stored in the temporary user space and once you reboot to your original OS you won't be able to access them again. So you need to turn on File Transfer mode, go to the actual directory on your PC and move them to your computer. They have the filenames "boot_a.img" and "boot_b.img" . After you're done, just reboot as usual and you'll get into your old OS.
Now you have the boot images, all that's left is to use Magisk Manager to patch them, enter fastboot mode, and flash the patched images using the following commands:
fastboot flash boot_a patched_img_A.img
fastboot flash boot_b patched_img_B.img
(Rename as needed)
And now your Y700 is rooted.
The linked Japanese webpage also talks about working Android 12 / 13 GSI flavors, patches, and ways to set up your Y700.
