Backing up kernal pre-root - Samsung Galaxy S8 Questions and Answers

Hi Guys
So I'd consider myself alright on rooting a phone by a guide,
Backing up the phone's ROM should be easy enough once you've got a custom kernel on there. I've installed enough kernels and roms to understand enough on my old S6, and sony before that.
But what happens if you want to back up the factory Kernel from your phone before rooting? Since you have to overwrite the kernel before getting root.
I know there is factory kernels out there for download, which work sweet, but having an international version of a phone, I've noticed that these kernels don't always work as they should.
Like for example back on my old samsung s6, I lost the ability to use Google play music, which forced me to use spotify a couple of years ago.
Is it even possible to back up a kernel pre-root for safety purposes? or should i see if samsung will provide that file?
Thanks Guys

Step 1: unlock bootloader
Step 2: install custom recovery
Step 3: create system backup
Step 4: root/flash/whatever you want to do
Step 5: **** up phone in step 4
Step 6: restore backup from step 3
Step 7: refer to step 4
FYI, the kernel is part of the BOOT.img

[Q] Coming up with a failsafe procedure for reverting back to factory defaults

Hi all,
[I originally posted a question about this in the General Discussions forum, before I realized that there were dedicated forums for each phone model. So please forgive me for effectively double-posting]
Totally new to Android, only got my Desire Z last Friday. I'd like to root my phone and play around with custom ROMS, but I'm worried if I ever need to return the phone for warranty purposes, and for when I buy another phone and want to sell this one.
So my objective is to make sure I have a failsafe way to revert back to my current stock HTC ROM before I start messing around with rooting/custom roms.
As I understand it, the generic steps for rooting/s-off/custom rom are:
- Gain temproot
- Gain permroot + S-OFF
- Install custom bootloader and recovery image (ROM Manager/Clockworkmod)
- Install custom ROM
So if I want to revert back to the stock HTC ROM, I image I need to do the following:
- Restore HTC ROM
- Restore original recovery image and bootloader
- Remove permroot and set S-ON back
- Remove all traces of the method to gain root/S-OFF
Is that generally correct?
I'm currently thinking about using the following procedure, but there's a few gaps in there still. I'd appreciate it if people could verify my procedure and fill in the gaps...
Permroot+S-OFF the phone
Step 1. Back up phone data
Planning to use HandyBackup for that, just need contacts, SMS and call log...
Step 2. Flash older HTC firmware
There's no permroot/S-OFF hack for firmwares >=1.72 at the moment, so we have to first downgrade to 1.33.405.5 using the method described on http://forum.xda-developers.com/showthread.php?t=905261 (steps 1-12)
After I do this, make sure I never ever upgrade this phone to >=1.72 again!
Question: this guide tells me to make a goldcard first. As I understand it that's only required if you have a branded phone. My Desire Z is not branded as far as I know, so is it correct to say that I do not need a goldcard?
Step 3. permroot+S-OFF
Follow steps 13-19 from the link above.
Better get the original CID here as well? How?
Step 4. Create a backup of the existing bootloader and recovery image
Question: how can I do this?
dd if=/.... of=/....
dd if=/.... of=/....
Step 5.Install ROM Manager
Step 6. Install recovery image from inside ROM Manager
Step 7. Create a backup of the phone using ROM Manager
This will be a backup of the stock HTC rom, which is rooted+S-OFF. I will need this later in case I ever want to revert the phone back to factory defaults
Now how to revert back to factory defaults:
Step 8. Restore stock HTC ROM using ROM Manager
Restore using the backup I created in step 7 above.
Step 9. Restore original bootloader and recovery image
Question: how can i do this?
dd if=/... of=/....
dd if=/... of=/...
Step 9. S-ON and remove root
Question: "gfree -r -f"? This link here: http://forum.xda-developers.com/wiki/index.php?title=HTC_Vision#Returning_to_Stock talks about using "gfree -r" to restore "partition 7", but I've not seen anywhere where this backup of partition 7 is actually created...
Step 10. Clean up after myself
remove psneuter, gfree, uninstall ROM Manager, Visionary, SuperUser
So, summarizing my questions:
- Do I need to make a goldcard/debrand my phone first?
- How can you make a backup of the existing bootloader/recovery image?
- How can I restore the original bootloader/recovery image?
Kind regards...
Just root your thing already. I'm not confirming anything or nothing in your very well put escape route...but worry about that later. Yes there's always going to be a way to unroot. Especially when we have the files nao.
Root via the wiki page to downgrade then use the rage/gfree method to temp then permroot.
You CAN (and should) backup your stock ROM, but there is no need to revert to it before unrooting. The method of unrooting restores a completely bone stock ROM anyways. The backup is just useful to keep around if you ever make a misstep installing a new ROM and need to revert back.
To unroot, follow the wiki to unroot lol.
As long as you keep a program like Titanium Backup up to date, you'll always have your apps and system data backed up too. This much extreme caution is not necessary as much as it pains me to put it that way. Just backup your apps and be smart when u install a new ROM and you'll be fine.

OK, then how (and at which stage) do I back up my stock ROM? Before or after downgrading and rooting?
To unroot, follow the wiki to unroot lol.
Click to expand...

But the wiki only says:
In case of the original T-Mobile G2 the stock rom is called PC10IMG_Vision_TMOUS_1.19.531.1_Radio_12.21.60.09b_26.02.01.15_M2_release_149459_signed.zip
Click to expand...
Click to collapse
Well, guess what: I don't have a T-Mobile G2. I have an unbranded Desire Z. So which stock rom do I use in case I have to restore, and where do I get it from?
Sorry for being paranoid, but given the trouble my wife would give me in case I somehow ruined my phone (yes, I'll get into trouble even if it's my phone and not hers ), a bit of advance planning is worth it to me.

Beginner needs rooting advice

Hi guys,
Just installed the 4.2.2 update on my Nexus 7, but I decided I wanted to go further. I have had plenty of android devices in the past, but I was always cautious about rooting them in fear of messing up. Well, after reading up about the benefits of rooting I think it's worth a try. I have read up on the basics of what rooting is and how to do it, but there are so many roms and kernels out there I have no idea where to begin!
So I saw an article on a website I frequent that has a guide on how to root the Nexus 7 with the newest update.
http://www.ibtimes.co.uk/articles/4...7-official-android422-jdq39-jellybean-ota.htm
What do you think about using this guide?
Also some side questions:
1.) Is there a way to backup my Nexus 7's unrooted state before I begin, so if I decide to go back to unrooted I can easily do so?
2.) Should I root my Nexus 7 on the 4.2.2 ota, or downloading it here on the forums? ( I assume they are slightly different)
3.) I don't want to ask what is your favorite rom, but what would you say is the most popular one around here? My biggest needs are stability, as well as better battery and performance.
Please excuse me if my questions seem strange or obvious. I've tried reading up more on this subject but quite frankly I don't understand it. I probably will get the hang of it. I was once a beginner to PC building but eventually I made myself a monster rig and overclocked the hell out of it. But since I'm thinking of rooting tonight, I would really appreciate it if someone would be kind enough to help me out! Thanks

The guide looks fine from what I skimmed, I would follow the toolkit found here though. It does everything for you basically.
1) Unlock your bootloader, install CWM, then nandroid backup from there. Transfer your backup to your PC.
2) No point in rooting your current rom if you are switching out.
3) I don't know which roms are the most popular but I switch between these two:
http://forum.xda-developers.com/showthread.php?t=1800268
-best customizing options and on the fly phone/phablet/tablet UI changing
http://forum.xda-developers.com/showthread.php?t=2098139
-stable, smooth and fast. Performance rom here.
Now you should hold off flashing these until the devs have integrated 4.2.2 into them, shouldn't take long...they are both working on them!

Thanks! So the tutorial I linked is just to unlock the bootloader but not to install a ROM correct? Then why is SuperSU included in this guide?

because some people just want Root on stock?
rooting =/= rom
Thanks guys! Last question. Should I have restored my Nexus 7 to factory settings before I updated to 4.2.2, or before I root? I know with the 4.2 update a lot of people recommended doing it since it increased performance. That was a bigger update though, so probably not, but I just want to be sure before I root that it would or wouldn't make a difference.
From what I've seen the easiest way to root the Nexus is 'Nexus Root Toolkit' which does the whole job with a couple of clicks of the mouse (you run it from Windows).
(Note: at the time of writing NRT v.1.6.2 doesn't support 4.2.2 so wait a couple of days before trying it and it will be updated.)
1) Do a full backup (MyBackup Pro is excellent for unrooted devices) as the process wipes your Nexus back to factory settings.
2) Connect your Nexus to the PC and copy the backup (the 'rerware' folder) to your PC (I'd copy everything, just to be safe).
3) Install and run Nexus Root Toolkit on the PC, enter the details for 'Your model type' and run the 'Full Driver Installation'.
4) Click 'Unlock', let it do its thing, then click 'Root' and after a while you'll have a fully rooted device.
5) Install MyBackup Pro on the Nexus, copy the 'rerware' folder back to the Nexus and restore it.
It really couldn't be easier and it works a treat.
Once you're rooted you'll find Titanium Backup is a better app as it can backup more stuff but it only works on rooted devices.
Or you could spend the 15 minutes to learn the right way and you would understand the process that takes place with the click of that 'magical button'.....then you wouldnt have to wait for a toolkit to update...
KNOWLEDGE REALLY DOESNT HURT.

[Q] Galaxy s4 and rooting?

Hey, before im starting to think about rooting my s4, i have some questions:
1: is it just as "easy"/hard to root and inject a custom rom as it where 2 years ago?
2: If the phone is rooted, is there a simple safe way to unroot the phone to be able to update the phone if some performance improvements are available?
3: If i want to load a custom ROM either the rom with a clean android or a cyanogen one, and later want to revert back to stock s4 rom like the stock i got now, is that easy to do?
4: If i end up bricking the phone, is there an easy way to un-brick it or "restore" it to it's original state like iphone and it's itunes restore function?
5: When my phone is rooted, can i take backup of the full samsung's touchwiz and android state in case something goes wrong and then restore the backup?
6: If i unroot the phone, can i still update the phone's touchwiz thingy?
7: If there is no way to take backup of my stock rom, can i then easily fetch the exact same rom i use now from a website to flash it back?
sorry for so many questions, but i need answers since my 2 previous rooting attempts on htc and lg phones failed and got bricked.

New Samsung User - Lollipop to Root

Good day, all.
My son has recently got a Verizon s5 and took the lollipop update. He now decided he wants root and all the fun that comes with it - and doesn't need to be lollipop; kitkat was fine.
Here's the problem. I am a Moto guy. I've always been moto and recently have turbo. I have NO clue what the build numbers mean, exactly how to start to get to where he wants to be. I've read these threads a dozen times and I think I'm ready to try. Any guidance would be greatly appreciated.
1. I believe I need Odin. And the drivers. No problem.
2. I believe I need to get back to kitkat, then root. with towel root.
3. He wants native tether capability to go along with his UDP, adaware, etc. Not sure I've found the kitkat app to do that.
4. I believe I can stop the lollipop update by freezing apps with TIbu, and I found the thread which says which apps to freeze.
5. He is not interested in custom ROMS yet so I don't think I'll be using safestrap ( I used that during my Droid Razr Maxx days so I am familiar with that).
So, if you can direct me to THE exact thread, that would be helpful. And the build / version of what I need to install. This is all like a foreign language at this point as the naming appears to me to be very different than my moto experience.
Thank you!

There is only one firmware that can be rooted. That is NGC. Odin the full stock tar file that is in the notes #4 of this post. Root with towelroot, download SuperSU from play store, update the binaries, reboot phone. You will be rooted on 4.4.2
There are several firmwares that are 4.4.4. NI2 or NK2 would probably be best but that is up to you. Get rooted first. Then decide where you want to be.

I will help you out with a full guide. I have nothing better to do right now. This will wipe the device.
Step 1: Download Odin, the Samsung USB Drivers, and the NCG Firmware. I have packaged them into a ZIP file for you here:
https://dl.dropboxusercontent.com/u/82986368/Revert_And_Root_4-4-2-G900V.zip
Step 2: Extact the ZIP file.
Step 3: Install the Samsung USB Driver. Do not plug in the phone while the drivers are installing.
Step 4: Turn off the device. Now, hold down Home + Power + Volume Down. Once the Download mode screen comes up, press the Volume Up key.
Step 5: Open the Odin EXE file, in the Odin-3.09 folder.
Step 6: Click the "AP" button, and select the NCG Firmware (the .tar.md5 file with the very long name).
Step 7: Click "Start." This will flash the full stock KitKat firmware.
Step 8: Once rebooted, skip through the setup process.
Step 9: On the device, go to towelroot.com and click the weird symbol. This will download Towelroot. Install the APK now.
Step 10: Open TR, and click Make it Rain. You are now rooted on KitKat.
Step 11: Install SuperSU from the play store, open it up, and install the binaries.
Freezing the app "SDM" in Titanium Backup will indeed disable the Lollipop update notification.
FoxFi is the tethering app you're looking for.
You can stop here, but if you want to get a custom recovery, follow these steps: (UPDATE: You said you don't need one. I'm just pointing you there in case).
Install "Busybox Free" from the Play Store.
Open it and click "Install."
Download this APK and install it: http://forum.xda-developers.com/devdb/project/dl/?id=7144&task=get
Open it, click "Agree," and then click Install Recovery.
You now have a custom recovery! Rebooting will ask you to boot into recovery or into normal mode.
That's it! Let me know of any problems. I will be active here today

You forgot one step. After making it rain, you download SuperSU from the play store, update the binaries, and reboot.

Woops! Just added it back in.
Gentlemen - success!
Wow. I was telling my son this would be "hard" and he laughed at how easy it was. Thank you, guys. Sitting at 4.4.2 for now, and we'll let him play with this a bit then go from there.
Sincerely, thank you for your help and guidance.

Shortcut to being rooted on N910VVRU2CQI2

Here's my Cheat Sheet ! This is the same procedure I used a while back with N910VVRU2CPD1 . I just updated the thread to work with the newer package.
1. Odin SamMobile N910VVRU2BPA1
reboot and factory reset a few times if needed to remove custom icon
2. Odin hsbadr's N910VVRU2BPA1_N910VVRU2CPD1_FullFirmware.tar HERE
3. Unlock with the samsung_unlock_n4-fix PROCESS use SIM card for data. Wi-Fi will not work at this point.
4. Odin twrp-3.0.2-0-trltevzw.tar Uncheck Auto Reboot, Manually boot into TWRP
5. Odin hsbadr's N910VVRU2CPD1_StockRestore.tar HERE
6. TWRP BETA-SuperSU-v2.71-20160331103524, Factory Reset, boot system
7. Use FlashFire to Flash firmware package SamMobile N910VVRU2CQI2
( ! System and Cache only ! )
Your mileage may vary.
Before I install my personal apps I remove as much Verizon, Samsung and Google spyware as possible.
-------------------------------------------------------------------------------------------------
EDIT: I was able to skip the recommended rooting and unlocking of 5.1.1 and make the jump I described.
I did not do the unlock using Kingroot until step 3 and I did not permanent root with Super Su until step 6.
No matter how you get there the phone has to be on [Firmware] [MM] [6.0.1] [RetEd/DevEd] Safe Upgrade to Marshmallow [N910VVRU2CPD1] then you can use FlashFire.
Hyperlinks are in the text to most of what's needed.

I keep seeing people saying there is a way to just flash TWRP and Magisk and you're done. I'd like to avoid SuperSU and the other root methods if possible. How would that work with your updated guide? Thanks
My main concern is the spyware the guys on Reddit bring up. Not to use kingroot and the like. Was there any resolution to this thread you posted Dr cool? Want to unlock my bootloader and flash the MODest ROM but I want to be able to avoid spyware too. Thanks for your work.

I'm not sure if it was spyware or what. but my phone performance better after cleaning out that folder.
Thanks doc. Is that a folder that gets overwritten when you flash a new room?
This says "Continue with sim card data because wifi wont work at this point."
What if we don't have any data right now? Will it still work?

Kingroot needs to connected to root. I never seen it work without a connection. N910VVRU2BPA1_N910VVRU2CPD1_FullFirmware.tar brakes wifi but you get it back with N910VVRU2CPD1_StockRestore.tar, I dont know why. It just works

My best guess now is it's some kind of provisioning issue that is cleaned up. Some of the files deleted you may actually need some day.
does this require the developer version? btw how do i backup
I seem to lose root after I flash CPD1. Still have TWRP though and says developer mode. What could be causing this?
Edit - When I flash stock restore I mean. I get rooted on BPA/CPD and then when I go to the next step I'm losing root and Kingroot says it has no solutions. I must be doing something wrong.

As long as you have TWRP installed still you are in good shape. At that point, you could either flash (through TWRP) SuperSu or magisk (on certain kernels magisk install errors out in twrp). The main objective is to get the custom recovery (twrp) installed on the 6.0.1 bootloader and once that's done it's just a matter of flashing your preferred rooting method or flashing a rom that has root included.
You can use an app like this to check your bootloader to make sure it's the right one.

That's weird. I flashed SuperSU but it didn't show up in the apps and when I tried to use Flashfire it said I didn't have root.
Got there. SuperSU had an error message when I tried to install it the 1st time after flashing full system. So I rebooted and installed again. Now Flashfire crashes and won't open. Switched to Flashify and it seems to work ok.
Edit - Stuck here for now. Flashify can't seem to find the CQI2 file and I still haven't been able to get Flashfire to work. Tried an older version and still crashes when it checks to see if I have the pro version or not.
In case someone else has the same problem with Flashfire, it's because the program expired April 1st, 2018. Turn the date back on your phone and it will load.
Finally completed it!!!
Ok, so the things I learned from my trials and errors.
1) DON'T flash the kernal and SU after you root with the N4 fix. I did this the 1st 15 times and could never get Flashfire to work later on. So skip all of the stuff in that post after you flash TWRP. Then flash the next firmware step.
2) Uncheck auto time and date on your phone and roll it back to before 4/1/18 to get Flashfire to work.
I'm sure there are some more things and I'll add whatever else I think can help the next guy along. Good luck! And thanks for the guide doc!
Note: Did the phone icon on your lock screen disappear as well when you were done? The camera is there on the bottom right like normal, but the phone is gone on the bottom left and it displays the charging info there now.
Thanks for this - it was helpful to make clear that in my mind that despite what other guides say, there is no need to unlock a Lollipop bootloader with a Lollipop kernel + ROM first, and that we can boot a Lollipop kernel + ROM with a Marshmallow bootchain and unlock the Marshmallow bootloader from the get-go.
I tracked down the CQI2 full Odin and I made hybrid Odins that get you "rooted on N910VVRU2CQI2" in fewer steps, following hsbadr's file naming scheme:
N910VVRU2BPA1_N910VVRU2CQI2_FullFirmware.tar.md5: MM CQI2 bootchain/firmware/modem, LL BPA1 ROM/kernel/recovery
N910VVRU2CQI2_StockRestore.tar: MM CQI2 ROM/kernel (no recovery - TWRP isn't overwritten)
These should be fine as drop-in replacements for the files mentioned in steps 2 and 5 of your guide.
Using these obviously means that you are unlocking the CQI2 aboot instead of the CPD1 aboot in step 3 while temprooted, and - importantly - step 7 is unnecessary to get to a CQI2 ROM, which is good because Flashfire is now expired :3
I doubt there's much of a real benefit to being on the newer aboot, but hey, why not.
Hey, no one answered my question from a while ago. So I'll ask again, does this require the developer version of the Note 4?

No, this will work with both versions of the verizon note 4.

Ok, thank you very much. I'll try and root my phone with this tutorial now.
Please help!!!!
I followed this link because its supposed to be a way to downgrade from 6.1.0 to 5.1.1 so I can unlock boot loader. However, these instructions make no sense to me. Can someone PLEASE help me. I've been searching and searching for a way to root my note 4 (N910VVRS2CQA1) and can't seem to find a way. I've never done this before so I'm pretty clueless. When I read these instructions, I just don't understand what I'm supposed to be doing. A lot of this tech lingo means nothing to me unfortunately. I'm starting to thing I should just give up the idea of rooting this Note 4 that's getting slower and slower and just get a new one. I don't really want to though bc I love the fact that you can replace the battery. It'd be much easier to just root and upgrade.....well, easier if I actually knew how.
