Mar 29, 2013 Ξ57 CommentsRoot and Install CWM Recovery on Verizon Galaxy S3 SCH-I535 Android 4.1.1/4.1.2
posted by Rakesh Shukla
Rooting an Android device has many privileges. Having rooted your phone once, you are able to use third-party custom ROMs and mods that require a custom recovery to be installed. Besides, there are hundreds,or say thousands, of app that are capable of doing wondrous things and enhance your phones performance and usability. But this humble eulogy of rooting cannot undermine the hazards associated with it.
Rooting a Samsung Galaxy device is much easier than rooting any device manufactured by other OEMs but when it comes to rooting a Samsung phone from Verizon, things get a little more complicated and rounded. However, complicated it might be, it cannot stop our great Devs to crack the nut. All props and credit for the method described here goes to XDA member open1your1eyes0.
Disclaimer:
Please note that the procedure of unlocking the bootloader, rooting and installing a custom recovery on your Verizon Galaxy S3 SCH-I535 is considered risky. Moreover, it will also void the warranty of your phone. Proceed only when you are sure what you are going to do and understand the seriousness of things. More than anything, be careful while following the steps.
Looking for Rooting Tutorial for Some Other S3 Variant?
Take a look all Galaxy S3 rooting tutorials here.
Prerequisites:
•Charge your phone to have at least 60% of battery juice.
•Rooting does not wipe any data from your phone but we would strongly recommend that you backup all your contacts, messages, call-log, apps, etc. Here are some good free apps to help you with backing up your data.
•Put your device in USB Debugging mode from Settings> Developer Options>
Required Downloads:
Since this tutorial is for Galaxy S3 I535 on Android 4.1.1 and 4.1.2 both, download the files accordingly- only different being the stock bootchain file. For the sake of convenience put all the downloaded files in one folder.
These are important but mandatory files. If you have them, just skip:
•Download the Odin tool and extract the zip on your desktop: Odin3-v3.07.zip – Mirror
•Download Samsung USB Drivers and install on your computer. Skip if you already have it: Download
These two files are meant to be downloaded by all:
•Download the custom Bootchain file: VRALEC.bootchain.tar.md5 – Mirror
•Download CWM Recovery: CWM6023TouchVZW.tar.md5 — Mirror
Download one of the following files depending on what you want:
•Download SuperSU file (for Root Only): CWM-SuperSU-v0.99.zip
•Download SuperUser file to (Root and Unlock Bootloader both): SuperSU_Bootloader_FIXED.zip — Mirror
Download one of the following bootchain files depending on firmware version of your Galaxy S3 SCH-I535:
•Bootchain file for VRBLK3 (Jelly Bean 4.1.1): VRBLK3_Bootchain.tar.md5 — Mirror
•Bootchain file for VRBMB1 (Jelly Bean 4.1.2): VRBMB1_Bootchain.tar.md5 — Mirror
Root, Unlock Bootloader and Install CWM:
Already made the preparations and downloaded the required stuff? It’s action time now. Be careful and proceed.
1.Copy the “SuperSU_Bootloader_FIXED.zip” file to your phone’s internal or external SD card.
2.Turn off your Galaxy S3 and boot it into Download mode: hold the Volume Down + Home + Power buttons simultaneously for a few seconds till you see a warning screen asking you to press Volume Up key to continue. Pressing this key will take you to Download or Odin mode.
3.Open the Odin folder and run the .exe file present there and then connect your Galaxy S3 to PC via USB cable. Wait till Odin detects your device and you see ID:COM port turning Blue and “Added!!” text at the message box below.
4.Now we will flash the custom bootchain file so make sure that “Auto Reboot” and “F Reset Time” are selected on Odin. Then click the PDA button and select the “VRALEC.bootchain.tar.md5″ file and click on “Start” button on Odin.
5.The bootchain file will be flashed in a few seconds and you will see “RESET!!” message with blue signal. Your phone will reboot automatically. Close the Odin window and disconnect the USB cable.
6.Now you need to install the ClockworkMod touch recovery. To install it, boot the phone into Download mode again (as you did in Step #2 above).
7.Relaunch the Odin, connect the phone using the cable and uncheck the “Auto Reboot” option on Odin.
8.Click on the PDA button, select the “CWM6023TouchVZW.tar.md5″ file and hit the “Start” button.
9.CWM Recovery will be flashed to your phone followed by “PASS!!”. This time your phone will not reboot automatically. Close the Odin window.
10.Now pull out the back cover of the phone and remove the battery. Place the battery to its place after about 30 seconds.
11.Then boot the phone into ClockworkMod recovery mode. To do this, hold the Volume Up + Home + Power buttons simultaneously. Keep the 3 keys pressed till your phone vibrates and when it does, release the Power button but keep the other 2 keys pressed till you a gray background with blue text the clockworkmod recovery written on the top of the screen.
12.Since it’s touch recovery, you can either select options by tapping, or using the volume and power keys.
13.Okay, now go to “install zip from sdcard> choose zip from sdcard” and select the “SuperSU_Bootloader_FIXED.zip” file.
14.Confirm your choice by selecting “yes’ and let the installation finish.
15.When it’s done, go back and select “reboot system now”. But before your phone boots, pull out the battery and place it back after a few seconds.
16.Once again, and for the third time. you will have to boot the device in Download Mode. You know well how to do it.
17.Relaunch Odin, connect the phone to PC, click on PDA button and select the stock bootchain file (either VRBLK3 or VRBMB1) depending on what file you have downloaded.
18.Click the “Start” button to initiate the installation. When it is finished, the phone will reboot automatically.
So, now you have a fully rooted Verizon Galaxy S3 SCH-I535 with unlocked bootloader and ClockworkMod recovery installed. To verify the root, download any app that requires root permissions. However, there is a specific app for the purpose and you can find it at the Play Store
Everything went sucessfully and my phone was rooted. I did encounter one problem and that was I couldn't get the CWM Touch Recovery to stick. I found out with the help of a few forum members that I needed to select "yes" on the propmt to overwrite the stock recovery. (the warnign I got stated ROM will flash back to stock. Would you like to fix this? YES= This can not be undone/ NO or Go Back. I was selecting go back because I was not sure on what to select and CWM would never stick it would always reboot back to stock. Last night I did select yes, and it worked fine.) I went back and fixed the issue, and now CWM Touch Recovery is flashed on my phone. I also used Terminal Emulater to back up my IMEI.
My question is, because I initailly did'nt flash the CWM Touch Recovery the right way (right way meaning selecting yes) does this mean I didn't unlock my bootloader? I'm a complete noob and just want to make sure I have things in order.
Thanks,

Take a look at this thread to determine if you bootloader is unlocked.

[Q] help pls problem with root on p6200

help pls problem with root on p6200
when i was root by this way i have issue
1) Install USB driver for Samsung Galaxy Tab 7.0 Plus to transfer files between the Android device and computer.
2) Enable USB Debugging Mode on the tablet to connect the Android device with the computer and use the Android SDK with it. [Press Menu>> Settings>> Applications. From there navigate and click on Development option and ensure the USB Debugging Mode is turned on.]
3) As the tutorial might wipe all data of the phone, create a backup. If the device is having any custom recoveries such as CWM/TWRP already installed then backup data using the recovery.
4) The device should have above 80 per cent of battery charge.
5) The Galaxy tablet should be factory unlocked and not locked to a particular carrier.
6) The tablet will lose manufacturer's warranty once it is rooted. However, users can reclaim the warranty back by unrooting the device later.
7) The recovery file and the Superuser file work only on the Samsung Galaxy Tab 7.0 Plus P6200. Applying these on any incorrect variant might brick the device. Therefore, verify the model number of the Galaxy device by selecting Settings>> About device>> Model number.
Steps to root Samsung Galaxy Tab 7.0 Plus GT-P6200 on Android 4.1.2 Jelly Bean and Install CWM Recovery
Step-1: Download CWM recovery file for Samsung Galaxy Tab 7.0 Plus to the computer
File name: GT-P6200-Recovery-tar.md5
Step-2: Download CWM flashable SuperUser zip. Copy it to the SD card of the tablet
File name: Superuser-3.1.3-arm-signed.zip
Step-3: Download Odin 3.07 and extract the downloaded zip to the computer
Step-4: Switch off the Galaxy tablet and boot it into Download Mode by pressing and holding Volume Down and Power buttons together
Step-5: Launch Odin on the computer
Step-6: Connect the Galaxy Tab 7.0 Plus to the computer using USB cable while it is in the Download Mode. Wait until Odin detects the tablet. When the tablet is connected successfully, the ID: COM will turn yellow with COM port number. Also, an Added message will appear in Odin indicating successful connection
Note: If the Added message does not come then try another USB port, try the one located at the back side of the computer. If that too does not work then re-install USB driver.
Step-7: In Odin, click the PDA button and select GT-P6200-recovery.tar.md5 file
Step-8: Verify the Auto Reboot and F.Reset Time checkboxes are selected in Odin. But uncheck the Re-Partition option
Step-9: Finally click the Start button in Odin to begin the installation process which would take few minutes to complete. Once the installation process is completed, a PASS message will appear under Odin indicating successful installation. The tablet will then reboot automatically
Step-10: Once the tablet boots up, turn it off. Then boot the device into recovery mode by pressing and holding Volume Up and Power buttons together
Note: In recovery mode, use the Volume keys to scroll between options and use Power button to select the desired option.
Step-11: In recovery mode, scroll down to and select install zip from sdcard then select choose zip from sdcard. Now navigate to the Superuser-3.1.3-arm-signed.zip file which was earlier copied to the SD card of the tablet
Step-12: Select it using the Power button and confirm installation by selecting Yes on the next screen
Step-13: Once the installation process is completed, return to the main recovery menu and reboot the tablet by selecting reboot system now
Samsung Galaxy Tab 7.0 Plus should be now rooted successfully on Android 4.1.2 Jelly Bean with ClockworkMod recovery installed. To verify the root, open the app drawer of the tablet and look for an app called SuperSU from the list. Also, to ensure the root access, install Root Checker app from Google Play Store.
when select Superuser-3.1.3-arm-signed.zip says

Update Samsung Galaxy On5 SM-G550FY (non-Pro) to Nougat Pro firmware - Detailed

As one of the previous threads in this section mentioned the same (that On5 Pro firmwares work on non-Pro On5 models also), I can confirm that it works on Samsung Galaxy On5 SM-G550FY (2015 non-Pro) model. The downloaded firmware was a latest On5-Pro Nougat version that I could find on https://updato.com but works with old non-Pro On5 model as well.
This post is "only" meant to chalk out the complete process.
Detailed instructions for people who've not rooted their Samsung devices before:
Steps to replicate the process:
Preparation for rooting first:
Make sure your phone battery is charged to 70% or more
Backup your device data
Make sure you install Samsung's Android USB Driver for Windows on your PC, if you haven’t already. >> Official link
Download the latest .tar image of TWRP for Galaxy On5 (it is compatible) >> Official link
Download and Unzip the latest version of Odin version >> Official link
Download the latest Super SU >> Official link
Now follow the instructions:
First you should enabled Developer options. If Developers Option is hidden, go to Settings > About Phone > Built Number (tap on it for 5-8 times)
Enabled USB Debugging and OEM unlock.
Install Android USB Drivers on your PC.
Connect the phone to you PC using the USB cable and copy the SuperSU.zip file into any directory of your internal storage.
Turn off your Samsung Galaxy Boot the device into Download Mode as follows: press and hold Volume Down, Home and Power buttons together.
When a warning triangle appears on screen, press Volume Up button to enter Download Mode.
Launch Odin.exe by click right and run as administrator on computer.
Connect your phone to the computer. Odin will automatically detect your phone and show the “added" message.
In Odin, tap AP button and find the TWRP Recovery file you downloaded earlier and select it.
Uncheck Auto-reboot in the options tab in Odin
Click Start in Odin.
Once the root installation is done, your phone will reboot and soon a PASS message with a green background appears in the left-most box at the very top of Odin.
Remove the battery and then re-insert it again.
Boot into “recovery mode”, by pressing and hold Volume Up + Home +Power buttons simultaneously
In the TWRP mode Swipe to Allow Modification
Tap ‘Install’
Select Storage and scroll to location of SuperSU.zip file.
Select the .zip file and swipe the bar to confirm. This will start flashing the .zip file.
Once the flashing finished you will see the ‘Reboot System’ option, click it to reboot your device.
After reboot, if the SuperSU App exist on your Application Menu on your smartphone it means you’ve successfully rooted your device.
Can take further help from here (works for this On5 model as well) >> https://forum.xda-developers.com/sa...nt/updated-root-instructions-samsung-t3747435
After rooting:
You can remove the bloatware first using any "root uninstaller" app from the Play Store. Be careful as to not uninstall any vital system apps.
Now go to >> https://updato.com and download the latest On5 SM-G550FY firmware (>1GB) by searching "On5" and sorting firmwares by date and selecting the region (for my model make the region was India (INS) >> You can use this Working link directly, as well
The above version is an On5 Pro Nougat version but works in old On5 models as well.
Final Steps:
Now again launch Odin.exe by click right and run as administrator on computer.
Connect your phone to the computer. Odin will automatically detect your phone and show the “added" message.
In Odin, tap AP button and find the firmware file you downloaded earlier and select it. You might need to first extract the firmware file.
Click Start in Odin.
The phone will reboot and you'll have updated your Lollipop/Marshmallow device to Nougat.

ROOT WITH MAGISK
.

Thank for that clarity .. i just get an Tab s6 and i needed i simple and recent tutorial.

This guide worked perfectly. The one with twrp didn't.
Thank you.

This didn't work for me.
3. Flash all files to your tablet and disconnect from PC when ODIN finished
4. Reboot tablet into recovery and format data and cachee ! Restart tablet and wait few minutes to load
I can't get into Recovery Mode to format. It freezes on the boot logo, I'll hold Volume Down + Side Key to power off, Volume Up + Side Key to boot into Recovery Mode but it just tried to boot normally and freezes on the boot logo.

Is it better to root first or flash TWRP.
EDIT: Duh!!

Before step 10 ensure that you have a Wi-Fi connection. I think Magisk requires it. Magisk would not produce the drop-down till I connected to the internet. Then everything worked fine.

Good man, thanks so much!

You need to restart tab after flashing BUT again in DOWNLOAD MODE...not in recovery ! Then flash TWRP and restart in twrp recovery.You need to untick AUTO REBOOT in Odin before flashing TWRP.

Not able to shutdown
After rooted with Magisk,my Tab S6 is not able to shutdown,no matter which methode I use,it just restart itself.
Does anyone have this issue?

worked perfect on oneui 3.1 aswell thank you

I rooted my Galaxy Tab S6 using the Magisk-only method after updating to Android 11. I had trouble with the post-Odin step (pressing power and volume up right after screen turns off) so I had to do the flash a couple more times before I got that right, and everything shows as rooted now.
However, my 256GB internal storage is only showing up as 32GB! Is that a firmware thing, or a partitioning thing? How can I fix it?

Used ther same method on my rooted tab with the May update (T865XXU4CUE1_T865OXM4CUE1_DBT) - magisk-patch AP, flash all files in Odin, after reboot the device is rooted.
BUT after another reboot (or rather shutdown and boot), root access is lost and cannot be restored in any way until I re-flash the device with the same firmware again.
Any solution to this?
6. Install Magisk Manager.apk and open it...It will do some patching updates then reboot itself.
7. Open Magisk Manager again and install Magisk zip from manager. Manager will root and reboot device itself.
Click to expand...
Click to collapse
This never happens. I even uninstalled Magisk Manager after patching, flashed the firmware, reinstalled the latest Canary Manager, still no patching or reboot happening.
Edit: just rebooted and shutdown a few times, root sticks. Before, I held VolUp as described in many guides until the "secured by Knox" logo appears, now didn't touch any button except Power.
Oh well...

Rooting SM-T860 OneUi-3.1 and installing TWRP (UPDATE: Updating to latest version without losing data)

(EDIT)
OneUI 4.1 has finally arrived, if you haven't got your Tab s6 rooted, you can just follow the instructions below. This new part is for the people who followed the guide to root their Tab s6 and now want to update to the new firmware version without losing their data. This guide is inspired in https://forum.xda-developers.com/t/...te-rooted-device-whilst-keeping-data.4245989/. But for simplicity of search I have decided to place it here
(END OF EDIT)
I ran into some problems and took some time to figure out how to install TWRP and root the tablet. The normal procedure by which you flash TWRP and then flash Magisk doesn't work as the download mode won't accept non-official files.
Then, once I got my tablet rooted by the patching method of Magisk, I installed TWRP with their app and got stuck in the logo due to not formatting the data.
After some research and quite a lot of time, I managed to get around that and be able to do everything.
Here is a step by step detailed guide of how to do so.
ATTENTION: These modifications void your warranty and may brick your device. I am in no way responsible for any damage you may cause. Follow this guide at your own risk
Requirements:
-> Latest version of the firmware of your model (I used this site which had the latest version and decent download speeds https://galaxyfirmware.com/model/SM-T860)
(To find which version to download, go into the Phone app, and type *#1234#)
-> Latest Magisk.apk file (https://github.com/topjohnwu/Magisk/releases)
-> Disbale_Dm-Verity_ForceEncrypt zip file (https://zackptg5.com/android.php#disverfe)
-> Latest TWRP img (https://eu.dl.twrp.me/gts6l (europe) or https://dl.twrp.me/gts6l (americas))
-> Official TWRP tool (Play Store)
-> Samsung drivers (https://developer.samsung.com/android-usb-driver)
-> Latest Version of Odin (https://odindownload.com/SamsungOdin)
-> SD Card or Minimal ADB and Fastboot (https://forum.xda-developers.com/t/tool-minimal-adb-and-fastboot-2-9-18.2317790)
(If SD card)
Copy Magisk, AP file from the firmware zip, Disable_dm zip and TWRP img into the SD card, else, you will have to use adb sideload
0. Create a backup of all your data (we are going to wipe the data of the tablet)
(Tablet)
1. Activate developer settings (go to Settings->About Tablet->Software information, and tap 5 times on build number).
2. Go into developer settings and activate OEM unlocking and USB debugging.
3. Turn off the tablet and turn it back on pressing Power + Vol. Down buttons to enter Device Unlock Mode.
4. Press and hold Vol. Up and in the next menu, press Vol. Up to unlock the bootloader (attention, this will erase all of your data)
5. Run through the setup, but be sure to activate the internet (this will prevent the tablet from relocking).
6. Activate developer settings again, and go into it to check that OEM unlocking is greyed out.
7. Install Magisk
(PC)
8. (No SD) Copy the AP file to the Tablet.
(Tablet)
9. Go into Magisk, press Install->Patch a file->Recovery mode (on)->Select file (The AP file).
10. Copy the patched file back into your computer.
11. Shut down the tablet.
12. Press Vol. Up + Vol. Down and connect the tablet to your computer with a USB to enter download mode.
(PC)
13. Open Odin, it should show that your device is connected.
14. Go to the settings tab and uncheck the Auto-Reboot option.
15. Flash all the files of the latest firmware, using CSC (not HOME_CSC) but substituting the AP file with the patched one. (With the WiFi version, you might not have a CP file, don't worry)
CRITICAL STEP (if not followed correctly, may lead to bootloop)
(Tablet)
16. Once the flashing is complete, press Vol. Down + Power during 7 seconds to restart the tablet. As soon as the screen blacks out, swap to Vol. Up + Power (and keep pressing even though it asks to press power) to enter the recovery.
17. In the recovery, navigate to Wipe data/factory reset with the volume buttons and press power button to select. Confirm and reboot.
18. While rebooting, you need to press Vol. Up + Power during 3 seconds (Until the press power to continue appears). This is due to Magisk being installed in the recovery partition.
19. Run through the setup again, but this time you need to login into your google account to enter the Play Store.
20. You should have the Magisk app installed. Open it and it will configure itself.
21. When it reboots, press again Vol. Up + Power for 3 sec.
22. Download the Official TWRP app.
(PC)
23. (No SD) Copy the latest TWRP image previously downloaded into the tablet.
(Tablet)
24. Go into the TWRP app and give it root permissions.
25. Enter TWRP flash and select the latest TWRP img
26. Go into the reboot menu and select reboot recovery.
27. The phone will reboot into TWRP.
28. Tick don't show this message again and slide to allow modifications.
29. Wipe -> Wipe data, Cache and Dalvik and Format data.
30. Reboot -> Recovery.
31. (SD) Flash Disable_DM-Verity zip, and then flash Magisk zip.
32. (No SD) enter the advanced menu and open adb sideload. Connect to the PC, open Minimal adb and fastboot and adb sideload the zip files.
33. Reboot system
Congrats, you have a rooted Samsung Galaxy tab S6 with TWRP installed!
FAQ:
1) Ok, I f* up, I am now stuck in the Samsung logo, what do I do?
Press Power and Vol. Down for 7 seconds, this will auto reboot your tablet. Then, as soon as the screen goes off, try to press Vol. Down + Vol. Up and connect through USB to the PC. With some luck, you manage to get into download mode. If you don't, repeat.
Flash the files with the Magisk modified AP, reboot into recovery and factory reset (follow the next instructions if you want to install TWRP), or else flash the stock rom.
2) I am seeing some screens with some warning messages, is that Ok?
Yes, it is normal, Samsung does that to scare people off from installing modifications on their devices. Can I take them off? Yes, but it is not a simple process. If you really want to, follow this guide, but adapting to the device (https://forum.xda-developers.com/t/...sage-on-samsung-a30-after-root-device.3954589). Another important thing is, when you want to enter recovery, you need to keep pressing Vol. Up + Power, even when the tablet displays the message that asks to press the power button.
3) Don't know... You ask

Works perfectly, thank you!

I have a question: to decrypt the internal memory which files can I flash?
