I tried it, but it didn't work. I think I downloaded a bad firmware tho. I am going to try it now. Btw. if you want an easy firm download I highly recomend Frija v.1.3.0. - only easy, fast and WORKING (at least for me) firmware downloader.

I am stuck at odin saying NAND Write Start!!.
Could anyone help me?

[Completed] R

Alright for the past two week I had searched every corner of the internet looking up on how to install the “MOAR ROM”. Just getting the same answer install with “TWRP”. And to install TWRP you had to root your phone. So now I had to search on the internet and find a tutorial on how to root my phone. In the end I had to go through three different tutorials on how to get the MOAR ROM flashed on my phone. And where I had to go to get the files to download.
Well so you don’t have to do the long, and arbitrary tasks that I had to go through. Here is a tutorial – Telling you from start to finish on what you need to do.
This is for the Sprint Variant of the Samsung Galaxy S5. I don’t know if this will work on other version of the S5.
I apologize on the crudeness of this tutorial, a lot of this was written from memory.
All of the software you need to download is provided by clicking on words that are highlighted in brownish tan-ish color
I don’t not nor do the developers of the software you use are responsible for the lost of data and/or lost of your phone. You assume responsible for modifying your phone.
I have not created any of the software provide in this tutorial.
Step 1. Make sure you have VPU1BOA6 (Lollipop) OS installed on your phone.
-To see if you have this already installed your phone.
- You go to your phones “Setting”
- From there go to “About Device”
- You will then see “Software Version” and underneath that you will see “G900PVPU1BOA6”
If you see “OA6” you are good to go on to step 2. for rooting your device. So Please Continue. If you do not see this that is okay all you need to do is either update your phone or you need to flash the appropriate OS on your phone. To do this continue on to step 1a.
Step 1a. If you fail to see “OA6” in under “Software Version” then you will have to download some files.
- You will need to download Odin
- Then you will need to download the OS “Lollipop”
- Once you have both of these move to step 1b.
Step 1b. Warning!!! Installing this OS will wipe your phone of all its data. Highly recommend that you create back of contacts, photos, videos, etc.
- Now unzip Odin, and run SM-G900P_OA6_FullRestore.exe (This is will give you the Lollipop OS it will unzip it to the file destination you wish)
-Run Odin, Click on the AP button – A window should appear, navigate to where you unzip the OS and click on it.
- Now it is time to move on to set 1c.
Step 1c. Now it is time to put your phone into Recovery Mode and to connect to the computer.
- Power down the phone, once the phone is power down hold the “Home + Power + Volume Down Buttons” Do not let go until you see text show up in the upper left corner of the screen.
- Now some of you might see a screen that gives you a Warning about custom firmware and roms. And press up on the volume on button to continue or press volume down to restart the phone. If you want to continue press up.
- If you have elected to press up then you are awesome and it is time to continue on your route to being rooted. Now you will see the Android Guy “Downloading” or something to that effect. Plug your phone into your computer
- Now move to step 1d.
Step 1d. Again Warning: You will lose your phone data. Continue at your own risk.
- Press Start, on Odin once your phone is connected to your computer. Let it do its thing. Go make some coffee.
- Once it has installed the new OS go ahead and setup your “Slight used Phone”
-You ready for step 2. I think you are.
Step 2. Alright you have decide to root your phone, because you love all the options the Android OS has already provided you. But you know your phone can do more and you want more and deserve all of it.
- So first thing you need is the rooting tool and Odin if you don’t have download it. You will also need to two other additional files. SUPERSU and Knox Removal Mod Do Not Unzip these two (2) additional files.
-Now that you have the all four (4) items downloaded. Unzip the rooting tool and Odin. Now run Odin and click the AP button and find the rooting tool you just unzipped. Now let’s put your phone into download mode and connect to the computer.
- To put your phone into Download mode shut it down and hold the “Home + Power + Volume Down Buttons” until you see a Words in the upper left hand corner of the screen and a Paragraph that Say “Warning. Custom firmware Blah Blah Blah…etc. Press Volume Up to continue or Volume down to restart phone” Press up then Android guy shows up with downloading underneath him. Connect your phone at this point to the computer.
-Press start on Odin. Let it do its thing it should only take to 5 minutes at the most. Now that it is done. Shut your device completely down.
-Go to step 2a.
Step 2a. You will need a Micro SD card. Add those two other files. To the root of the SD card.
- Move to step 2b.
Step 2b. You need to put your phone into recovery mode.
- Your device should be completely shut off now. To put into recovery mode you need to hold down these buttons (Home + Power + Volume UP Buttons). You should see in the upper left hand corner of the screen text saying Recovery…
- You will see a list of options you will want to click to on “apply update from external storage” Find one of the two files you add to the root of the SD card and click. It should start to apply the update. Once that is complete. Repeat the process from Step 2b. for the other file.
- Go to Step 3.
Step 3. So you have decide you like to play risky and rooting just wasn’t cutting for you Daredevil.
- Go to “Play Store” Type into the Search bar “TWRP” – Install “TWRP Manager”
- Once it installed, Open the application, Grant the application root access. Now that the application has root access click on Menu icon in the upper left hand side. Once there go to “Install TWRP”.
- Click on “Device Name” and scroll through the device list and find the “Galaxy s5” and click it. It will then go back to “Install TWRP” page. Now press “Install Recovery” And let it work.
-Go to Step 4.
Step 4. Assuming everything for you so far has gone to plan. The next step is to install MOAR (Mother Of All Roms). Do not unzip the file.
-Connect your phone to the computer.
-Now that you have download MOAR. Move it the “Download” Folder on the SD Card. It will make easier to locate later.
- Now power down the phone and go into the recovery menu. To do this make sure your phone is off and now hold (Home + Power + Volume UP Buttons). Once there click on “Advance”, Then “File Manager”. There you will a list of options scroll until you see “external_sdcard”. Now you will see another list scroll until you see “download”.
-Now find the “MOAR” file. Click it, a couple of options will show up and press “Move”. Now a list will show up, scroll through it and locate the "sdcard”. Another list will show up, scroll through it and locate “TWRP” and press “Select” in the lower right corner and let it do its thing.
- Now go back to the Main Menu. Once you get there click “Install”. You should see the MOAR file, click it. It will take you to another screen and it will ask you to “Swipe to Confirm Flash”. After that your coffee should be done brewing and you might want to get a bagel while you are at.
If you get a couple of errors after installing MOAR, remove the battery and then stick back in and it should correct your problem.

[Guide]How to root Samsung Galaxy C9 pro (SM-C9000)

Hi! After struggling in rooting my C9 pro (SM-C9000, TGY) due to the lack of a proper guide, I decided to provide my guide to the community.
Of course, I don't take responsibility for damages etc. etc. Read the entirety of the guide before doing anything.
Useful shortcuts: Holding down power+volume down for a couple seconds force reboots from almost anywhere. Vol up+home+power while booting boots into recovery. Vol down+home+power boots into download (odin) mode.
Step 1) Fetch the required files(sorry I can't post direct links):
Nougat 7.1.1 firmware from sammobile
Oreo 8.0 firmware from sammobile
Odin https://www.xda-developers.com/update-firmware-any-samsung-phone/
Magisk Manager https://www.xda-developers.com/how-to-install-magisk/ (The link that says "Download the latest Magisk Manager APK here")
ADB https://www.xda-developers.com/install-adb-windows-macos-linux/
CROM Service apk from apkmirror
Step 2) Prepare the files
Unlock developer options on your phone by spamming Build Number in Settings> About Phone> Software Information. Enable USB debugging from developer options. Connect your phone to your PC via cable. Extract ADB (platform-tools) on your desktop (or other location). Extract Oreo firmware. There should be 5 files. Copy the one that starts with AP into platform-tools folder. Open the platform-tools folder. Hold down shift and right click inside the folder. Choose "Open PowerShell window here" from the context menu. Type or copy-paste
Code:
.\adb devices
to start ADB. On your phone, check "always allow on this PC" and click OK when prompted. Enter the code again and check if a device appears on the list. Then type
Code:
.\adb push AP_C9000ZHU1CSC1_CL14667562_QB22709761_REV00_user_low_ship_MULTI_CERT_meta.tar.md5 /sdcard/
.(Change the name of the file corresponding to yours. You can change the destination to another folder in your phone. Ex. /sdcard/download/) This will transfer the file from your PC to your phone. Do not drag and drop the file. This might corrupt it, causing a bootloop upon installiation. (Happened to me initially. Recovered & used the push command to get it to work.). Transfer Magisk Manager's apk to your phone or download it directly from your phone(you can drag and drop this one, as it won't install if corrupted(it won't corrupt)). Install Magisk Manager on the phone(Enable sideloading if asked). In the app, touch the topmost install button and touch install again in the next screen. You will have two options: "Download zip only" and "Select and patch a file". Choose "Select and patch a file", then locate the AP file you transferred to the device. Magisk manager will patch the file and generate magisk_patched.tar in /sdcard/download/. In ADB, type
Code:
.\adb pull /sdcard/download/magisk_patched.tar
This will transfer it to the platform-tools folder. Again, don't use windows explorer to transfer. That will most certainly corrupt the file.
Step 2.5) Backup
Backup your data (you can use smart switch desktop program paired with mobile app to backup most of the stuff). Remove your google account from the device.
Step 3) Install Nougat 7.1.1
Extract Nougat 7.1.1 firmware. Extract odin. Run Odin.exe (might have version in name). Click OK. Factory reset your phone (You can do so from settings or recovery mode.). After the reset, reboot into download mode. It will ask if you're sure you want to install unofficial software, choose continue (If I don't recall incorrectly, the button for that was vol up). Plug your phone into your PC. Odin log should say "added!!" and you should see your device in one of the rectangles above. Now select the tar.md5 files extracted from the 7.1.1 firmware. Click the BL button, locate the BL_etcetc.tar.md5 file, click open. It will check the md5 for a second then let you click the next button. After choosing the BL(bootloader), AP(system), CP(radio) and CSC(localization) files (USERDATA button should remain empty, HOME_CSC file has no use) make sure only F.reset time and auto reboot are selected in options. Click start to begin. After flashing, it will do another factory reset and show you the setup.
Step 4) Unlock Bootloader
Skip everything in setup, then unlock develper options and you should see "OEM Unlocking" option that was removed in OREO firmware in there. Enable it. Next transfer the CROM service apk to your device (or download it directly). Install the app. Open it. Unlock the bootloader. (This step is required because C9000 is a Chinese phone)
Step 5) Install Oreo again
Boot into download and connect to odin. You can use the reset button to empty the buttons. Now select BL, CP and CSC files from the extracted oreo firmware. For AP, choose magisk_patched.tar . Start. If the installiation fails, you didn't unlock the Bootloader properly. The phone will reboot and factory reset a couple times. When it boots up, you'll have magisk installed.
Step 6) Things to do after rooting(optional)
First of all, magisk can hide root from Google, but not Samsung. Samsung Health, Knox secure container, Maximum power saving mode and Samsung pay won't work after you root. NFC will keep turning on on its own unless you uninstall Samsung pay. A samsung package (I'm not sure about the name but I think it was security log agent) will keep sending an unblockable notification offering to unroot. Uninstall that too, and you'll have a stable experience.
Recovering from fails:
If download mode refuses to install because of unofficial binaries, the bootloader isn't properly unlocked. Wait a couple seconds and force reboot with the key combination. Since it couldn't flash the system, that should reboot back to download mode (or recovery. in that case, choose "reboot to bootloader"). Install the official firmware, unlock bootloader and try again.
If the magisk_patched.tar file gets corruped and you flash the corrupted file successfully, your device will get into a bootloop. After the install, odin orders the phone to reboot into recovery to factory reset, but since the system image is corrupted, it won't be able to boot and produce a kernel panic. This will cause the phone to reboot, which will fail and cause it to try to reboot again. Since the phone doesn't get past the splash screen, this bootloop cannot be interrupted by button shortcuts. You should wait for the battery to die out for the bootloop to end. (It should take a day at max. Wrap a towel around it to block the vibration sounds if you want) After battery gets depleted, you need to perform a quick maneuver. You should plug the phone into a power supply (preferably your computer) while holding down volume down+home+power buttons. If you do it right, it will boot into download mode. (Otherwise, it will bootloop again. Simply unplug, wait for it to stop and try again) Flash the official firmware and repatch the AP file. Just in case you run into this issue, I recommend having less than 10% charge in your phone while flashing, just to make the wait time shorter.
Important: Check your firmware's baseband version from settings before flashing. In C9000ZHU1CSC1, CSC1 is the system and U1 is the bootloader version. Compare the bootloader version to the firmware you're going to flash and make sure they match. You can't downgrade bootloader versions. Flashing a previous version will brick your phone. (Probably permanently) This shouldn't be an issue since sm-C9000 has only one bootloader version, but check it anyways just to be sure.

Have you tried this method and phone working fine will there will be any problem if i use this method for rooting c9000?

Yes, I did root my SM-C9000 using this method, and it is working nicely. Obviously I lost access to Secure Folder and Samsung Pay. You should be able to install the Play Store version of Samsung Health. Maximum Power Saving froze the phone the first two times I enabled it, but it's working fine now. One unexpected caveat is that mobile hotspot started to turn itself off if mobile data is enabled even though my carrier has no restrictions on using hotspot. You can't share your data connection using Bluetooth or usb cable neither. You can still use the hotspot for creating a local network. Other than those, I didn't experience any problems after rooting. While I was rooting, I did the mistake of using MTP to transfer the image and as a result my phone bootlooped for half a day but if you follow the instructions, that won't be a problem.
Of course, I don't guarantee anything and don't take responsibility, but there is no reason anything should go wrong.

Sorry for responding late. Yes, that is the exact model that I have and rooted using the method in the post. If you feel confident, you can follow trough it and root your phone. You can grab the required firmware from Sammobile. Keep in mind that after rooting some features might stop working (like hotspot and knox-related features). Good luck!
I got the same model of Samsung phone. I follow the steps but till step five, when i press open the files in odin and press start button, the odin will disappear in my computer. Then i try again and it failed. My phone shows: unsuppoted dev types. Here are my photos. Do you have any ideas? And i dunno how can i redo it again to root my phone. Would love to see helps from you, thanks!

Sorry for the late response. Searching that on the internet, it seems you might be using an old version of Odin. Please make sure you're using 3.13.1 and try again

[ROM][A51] HAVOC OS for Samsung Galaxy A51 [CUSTOM ROM]

Hey Guys,
Before you dive in, irrespective of your reading speed read this carefully and slowly for better understanding but if you cannot focus and read it slowly then you better give up music for a few weeks.
About the Device
Before you jump in and get your hands dirty.. you should know that what you will be installing is Generic System Image, It is not specifically made for your device so if you are going to install some other GSI other than this, you might face some issues.
If you are a beginner, you should Go Through Project Treble, just for the sake of knowledge.
Also Galaxy A51 has A/B partition and Supports Project Treble though remember that Treble Devices are not same as A/B devices and Vice Versa.
Things You’ll Need
A Computer (not an iPad)
Internet [requirement around 6 gigs (4.8 gigs optional, for downloading stock Firmware, Highly Recommended)]
Samsung Galaxy A51 (will not work on A50)
Patience and a madcap attitude.

Bugs
A small random issue in Auto Brightness
If you root with magisk and install modules, after you reboot your phone will get into a bootloop. Use Phh_Magisk but I aint sure if it’ll work or not Your call madcap.
NONE OF THE FILES IN THIS TUTORIAL HAVE ANYTHING TO DO WITH ME. If SOMETIHING HAPPENS I AM NOT RESPONSIBLE. ONLY DO IT AT YOUR OWN RISK.
Troubleshooting.
If you find errors in twerp, such as unable to mount vendor or system_root, or data. Then you got to install the stock One Ui Back again, therefore it is highly recommended to keep with yourself the stock firmware. You will need It. And it is 4.78 gigs. You can download it from
Model : SM-A515F - Galaxy A51 — Samfrew.com
To reinstall the stock firmware first extract it and the open odin and repeat steps 8 and 9, once your device is detected in Odin press the respective buttons and select the respective files such as for BL button select the file With BL in the name. Do it for buttons, BL, AP(once you select the file it will take long for it load into odin so do not panic and let it load, it might become unresponsive but use patience and wait.)CP , CSC. Click on start and you’ll have ONE Ui back on your device.
To Lock the bootloader repeat steps 5 and 6.
If you still want more stability and Control You can install a different Kernel NDataX from (@Hendamanu) https://forum.xda-developers.com/m/hendramanu.11224917/

Or you could just get your AP file and extract your boot.img.lz4 (use lz4 from github), put it on your phone and patch it with Magisk, then flash the VBMeta that this thread has in Odin, reboot and erase the cache and data in the stock recovery, rebooting to download mode again and flashing your magisk patched boot img in a tar file.

I agree with you. You can also use this way. However, using Magisk does all the jobs makes life easier and I am a bit lazy
Hi! I'm new into rooting and I just wanted to know, What's the risk of bricking when using magisk? I've rooted an old phone successfully via TWRP tho this way seems a bit more direct, and can I choose any region during the official firmware download?

The worst that would happen is a bootloop, which you can easily fix with a factory reset (not a good solution, but at least it works). The only dangerous part is installing the wrong TWRP version or a failed Odin flash, but no bricks. Odin mode will almost always work. Just make sure you have a charger in good condition.
As for picking regions, I'd just pick the phone's original region, if I were you. I'm not actually sure if region is tied to the device itself but better safe than sorry.

To check your Buld Number or Build Version, before you proceed doing any stuffs, type on the phone keypad this >>> *#1234#* and it will show on your device screen

I am not familiar with the A22 series, but I will say this: I'm rather wary of questionable root solutions, especially those that aren't open source. This is why I personally prefer Magisk - it is completely open source, so anyone who would like to examine the code can do so.
Sorry, when i See this tutorial, my phone has updated to android 13. Could this step possible to do now with this android version?
Very much thank you for the information!
have successfully run the tutorial above. even already using GSI rom android 13 from pixelExperience. but the network you get is stuck on 4G. are there any tools or tutorials to restore the 5g network.

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?
