Hello. Please be gentle. I'm new to Systemless Root and need some clarification. I've done a lot of reading about it but still need some info. Im not bashing anything or anyone, I'm not trying to be a wise ass, I'm genuinely confused. From the vague installation process I read somewhere it seems that u already need to be Rooted with TWRP installed to install Systemless Root. Right? So what's the point of rerooting a phone thats already rooted? I would think it would be more useful to have it as another root method. So we can start off Locked and Unrooted, then use Systemless to root. Currently my N6 is locked and Unrooted because I have no use for Root at the moment yet all of my previous Android phones have been unlocked and rooted. Please explain to me what I'm missing here. Thanks guys. Happy New Year to u.

Read this http://forum.xda-developers.com/showpost.php?p=63197935&postcount=2 and this http://forum.xda-developers.com/apps/supersu/wip-android-6-0-marshmellow-t3219344 for starters. BTW Google is your friend and you can`t be rooted to use systemless root and obtain root.
I'm probably a lot less experienced than gee2012 and many others in the forum, but here's my very high-level understanding. I hope that the more knowledgeable members can add to or correct this as necessary.
First, you need to unlock the device (fastboot oem unlock), since you can't do much with a locked device. Not only that, but time and time again I've read pleas from users saying "My device is bricked and I didn't unlock it so I can't now enable developer options" - the responses have been generally "Sorry, you're stuffed then, send it back". Unlocking wipes the device, so make backups of whatever essential data you have.
You don't need to install TWRP permanently in order to root. I myself (after asking members for advice) temporarily booted into TWRP (fastboot boot twrp.img - when you reboot from TWRP it disappears and you're back to stock recovery). While TWRP is temporarily running, you can use it to install SuperSU.
The benefit of the new SuperSU (and also doitright's systemless root method) is that it maintains a stock system image, so in theory you have the benefits of superuser root but you can still get OTA updates, which are now much more frequent because of the security amendments. Chainfire (the SuperSU creator) says that he was able to install an OTA after having used the SuperSU unroot function, though he then had to re-root.
Hope this helps - and that it's correct...

Thanks man. That makes certain things more understandable. The thing I still don't understand is the actual install process. I'm am stock, so ur saying I would just have to unlock BL then temp flash TWRP to flash the SU zip? If not what are the exact steps for installing?
BTW I'm on 6.0.1 MMB29K

Tip: instead of flashing TWRP you can also boot it up ( fastboot boot nametwrp.img) to flash zip files and keep your stock recovery if you want to.
@gee2012 - "Install BusyBox from Play and you`re done"
I still don't get what exactly Busybox offers. I've been running fine on Marshmallow for several months without it. I installed it once because it was suggested as a fix for the constant nagging of AutomateIt Pro to reboot, and it made no difference, so I uninstalled it again.
Can you (or anyone) give me specific examples if where it actually makes a difference? Which functions won't work without it? I haven't come across any yet as far as I know.
Busybox is the space efficient way of the basic Unix commands like ln, pwd, chown, chmod, etc. So all apps that want to do some low level file system dabbling, like Android terminal, Titanium backup, or Linux installs, they need it. https://en.wikipedia.org/wiki/BusyBox
From Marshmallow, Android now uses toybox instead by default, which is quite the same, with a little different licensing. It's also in the AOSP source, so all user built AOSP roms already have toybox, so there's no need for busybox to install.

Apps like Rom Toolbox Pro, Franco Kernel Updater and Kernel Adiutor and lots of other application like Xposed framework (and its modules) and most (if not all) of the custom roms will not work (correctly) without BusyBox. All custom roms anyway have a BusyBox version by default installed Busybox https://en.wikipedia.org/wiki/BusyBox and https://www.google.nl/url?sa=t&rct=...6Z0ltw&usg=AFQjCNG-nKYoEI3kiDm4pgtRWbXFRTpI6A for instance.
Its an essential app for when you are rooted and want to do more with your phone and its not smart to not install it
Thanks, both. I like istperson's comment best : "there's no need for busybox to install." That would be why I haven't seen any negative impact from not having Busybox then. Still, money well spent to help development...
Hi There,
I've the Problem that I havent't TWRP-Recovery and SuperSu after Updating to OOS 4.1.1 and Android 7.1.1.
Do someone know if i had to flash TWRP with qiping all Data? Or is there a Way to Flash TWRP and SuperSu without wiping? =(
Sorry I'm new to Android and started with the oneplus 3t. So i didn't know that i hadn't to update the Phone.
Or is the best opinion for me to choose a custom rom? But there are so much, i don't know what to choose.
Thanks for help! =)
Neither TWRP nor SuperSU will wipe anything.
It's totally up to you whether you need a custom ROM or not. If you want features like switching tracks just with your volume keys, you'll totally need a custom ROM since stock ones don't provide this feature. But this is just one example of many.
Regards.

Hm okay, cause when I got my one plus I flashed trwp and had to wipe everything, cause of the encryption or something like that.
I'll try my best today evening, hopefully nothing will go wrong :-O
What do I need to center the clock?
I'll flash trwp and supersu and anything to center the clock today evening.
Don't know if I need a custom rom, are there reason for a custom rom?

If you need help with anything, just ask.
I never had to wipe anything. I just wipe the phone when I want to remove the encryption.
EDIT: regular security patches is one big reason for me to install a custom ROM.
Thanks, I'll ask my questions
But why did the update delete trwp and supersu?
I was happy with OOS but missed the future of centering the clock.
May I ask which custom rom you use?
Updates remove SuperSU because they essentially flash over all non-user partitions (everything except /data, where your files, settings and user apps are stored). To root the OS, SuperSU installs its files in the /boot partition, which gets overwritten during ROM flashes. Root gets deleted any time you flash any mod (including most custom ROMs, since they also replace /boot). The only exception to this is if you flash a custom ROM that comes pre-rooted.
TWRP does not get deleted immediately during flashing, but rather when you first boot up afterwards. OOS will attempt to replace any custom recovery with the stock recovery when it first boots up after updating. You can get around this by either flashing TWRP again, or rooting immediately after flashing a ROM update, before you reboot (flash ROM, wipe cache/delvik, flash root, reboot). Most custom ROMs will not replace your custom recovery.
There's a few threads containing OPSystemUI.apk mods in the Themes, Apps and Mod section, though most of them also contain a bunch of other graphical modifications. If you only want to center your clock and nothing else, it can be achieved by modding OPSystemUI.apk yourself, though there is a bit of a learning curve to it.

You are mixing things up a bit but don't worry, I'll explain.
You need to unlock the bootloader first, and that always wipes your data for security reasons. So if your phone is stolen, the thief won't be able to access your data by installing TWRP or a custom rom. After unlocking you install TWRP (custom recovery), and use it to flash stuff. (roms, mods, etc)
After that you only lose data if you (or a rom) mess things up, and your data becomes unaccessible, or you relock your bootloader for whatever reason. That's why you should always backup to a computer before doing major flashing/upgrades, etc.
If you upgrade the rom you'll lose root and/or TWRP, but you can flash it again as explained by others.
Hi there,
so I've flashed TWRP and SuperSu again. You are all right, i haven't to wipe anything. I really mixed up things. But now everything is working for me.
Okay, i have to learn how to get my OPSystemUI.apk modify it and flash it back?
I will seach the threads and learn.
Hi guys. I got this device today and am very happy with it.
I'm used to rooting my devices, so I want to root this one too and was hoping you could help me a bit.
I have the Oreo update installed and I see there are some TWRP that work with oreo. What is the best one to use with stock rom? I only want to root so I can install adaway and lucky patcher. Also, if an update comes later this year, like android P or something, can I switch back to the stock recovery, install it and then switch to TWRP again?
So, basically, where can I download stock recovery for Oreo, what TWRP should I use?
Thank you very much

I am pretty sure you need TWRP. Here is a good guide: https://forum.xda-developers.com/p10-plus/development/magisk-p10-p10plus-t3752482
I do not know how to update with root. I am afraid it involves reinstalling the original recovery and a factory reset.
Unlocking the bootloader is currently a bit of a hassle since the unlock webpage is down. You'll have to contact Huawei Customer Service to get the code.
Hello,
I currently have the following:
Phone: OnePlus 3T A3003
Recovery: TWRP 3.1.1-x | blu_spark v37
Rom: RR-N-v5.8.3-20170603-oneplus3-official
I installed all of this after hours of googling last year. I now want to upgrade but I am not finding many helping guides are upgrading (rather than installing from scratch).
I downloaded RR-O-v6.1.0-20180627-oneplus3-official and tried to install it via TWRP (after backing up and wiping some stuff). But I got the an error stating something along the lines of "this rom is for oneplus3/t" and your device is "". Googling lead me to believe I needed to update my recovery. So I downloaded TWRP-3.2.2-0oneplus3.img but I really have no idea if I should be installing this? Last time I installed the blu_spark variant but I have no idea why.
Anyway, my question is:
Given the above, please could someone give me a laymans guide to updating my Custom ROM and which things I should install and in which order.
Thank you!

Clean Flash:
1) Latest Official TWRP (Can be done from within old TWRP)
2) Reboot Recovery to new TWRP
3) Wipe
4) Latest Firmware (OB29)
5) ROM
6) OpenGapps Arm64 8.1 Nano or Pico
7) Root Optional
Don't forget to Nandroid first, and it might be a good idea to remove any security measures on your current setup too. (Fingerprint/Pin/Pattern)
Queue up the zips for Firmware/ROM/Gapps and flash in that order together.
Thank you,
Some follow up questions:
* What should I be wiping during step 3.
* Should I install TWRP 3.2.2, does it matter that I currently have the blu_spark variant? (I don't even know what blu_spark means)
* I am just reading about firmware. I am assuming I need OB29 to work with RR-O-v6.1.0-20180627-oneplus3-official? Is that a simple process?

Just follow the steps. The TWRP you download will be an .img file. In the TWRP Install menu press the button for Image to flash the .img file.
For step 3, from the Wipe menu just swipe to wipe.

Thank you, final question. I note you advised to remove security. I changed from 'Pin' to 'None' and gave me a warning about removing it which I agreed to. It still states my phone is encrypted however, and I still need to enter my PIN when restarting. Will this be a problem?

I believe removing your stored fingerprints removes the boot PIN. Don't stress if you can't do this, it's just an additional precaution.

Pin/password and fingerprints are two different things. Fingerprints are just a convenient method of authenticating. Removing them does nothing for the actual security with is pin/password.
The reason for removing the lock screen password before taking a backup is that if you install a new ROM and set a password and then restore your older backup, you can't get past the lock screen password. So, remove the password before taking the backup and then you can restore it later and set a new password.
I find the better option is to not remove the password and then, if you need to restore the backup after having changed passwords, you can delete the passwords of the restored backup in TWRP from Advanced>Terminal with these commands:
Code:
cd /data/system
rm -f gatekeeper.* locksettings.*
Changing the pin/password to none doesn't wipe out the on-boot password. However, when setting up a new password and selecting to not set an on-boot password will remove the current on-boot password for some users, but not for others (it doesn't for me).

Thanks guys.
I followed your instructions @DirkGently and it worked a charm.
What you recommend for rooting the device and is as simple as flashing a zip file like above?
Also, is the recovery on a separate partition? So if I mess around flashing firmware/rom/apps and mess up, I'll always be able to boot into the recovery partition and flash again?

Yes and yes, but firmware may be tricky and messing up too much may render phone unusable. Messing with ROMs is fine though.
Thanks for the reply.
I note that on the Magisk page it states:
"If you plan to flash a custom kernel, flash it AFTER installing Magisk"
I have already installed a custom rom, will this be an issue?
Sorry for so many question. I get really nervous about this stuff!

That's ok of you asking questions, that's what this forum is about.
You should have got no problems if you're running a kernel shipped with custom ROM. Custom kernel is like EX, Mady's Xtended, Franco and so on.

You don't need to worry about Kernel stuff. RR already includes Caesium Kernel. You chose a good ROM by the way!
Here's a little information about Firmware. The OP3 and OP3T have unified builds. This means that in some cases the same Custom ROM can be used on both. There is some device specific software though so this has to be separated out and treated as independent from the ROM. This is what we refer to as Firmware. When Oneplus release new builds they include the updated Firmware in their Official ROM. If you look at the Firmware thread i linked you to, you'll see that kamilmirza takes the Firmware from the Official OOS builds and makes them available as flashable .zip files that we can use on Custom ROMs. Bookmark his Thread for future use.
There is no need to stress about always being on the latest Firmware for your Custom ROM, just ensure it is the Firmware intended for your device. The version you flashed earlier will probably do you for a while. At the same time, if you do always want to be on the latest, there's no reason not to. There's little to be gained by it though. If you're following the RR thread you'll probably see people mention it when the ROM requires a new Firmware. Again, don't stress about it.
As far as flashing Firmware, you can do it any time. You can do it before flashing an updated build of your ROM, or on it's own in a separate visit to Recovery. It's not particular either way. I would stick with the Open Beta Firmware, which people usually abbreviate to OBXX, i.e OB29. Just remember what you flashed so that you know which version you are using.
Now that you're rocking your Custom ROM you're next questions will be about updating it. This can be done easily and safely by Dirty Flashing. I've done dozens of updated builds since my last clean flash and everything has gone perfectly every single time.
Dirty Flash:
1) Download new ROM build (and Firmware if applicable) to Internal Storage.
2) Boot into Recovery
3) Nandroid Backup
4) From Install Menu, flash Firmware (if applicable), and ROM.
5) Wipe Dalvik & Cache when prompted. (BillGoss will tell you it's not necessary. It doesn't hurt either way, so up to you!)
6) Reboot phone.
For a Dirty Flash, you do not need to use the 'Wipe' Menu at all.
I always take a new Nandroid before flashing an updated build. I will have had a whole week on the previous build so i know i'm not backing up a bug and the backup will be as recent as possible if a problem occurs. Once i boot back into the phone i delete the old Backup. The new one is there if i need it. Always have that one recent Backup, just in case. As i've said, RR is great and i'm yet to run into a problem with it. From now on you can Dirty Flash the updated weekly builds with little to worry about and with a Backup to fall back to if anything goes wrong.
I don't mention Magisk because i don't use it, and i don't advise others use it. Unless you need Root access for something specific, don't bother. Half the threads on XDA are about problems with Magisk. Avoid the added complication if you can. Now this statement will trigger the Magisk fans, but nobody has ever had a bug or failure with something that they did not flash in the first place. Keep it as simple as possible.
Hi,
about 2 years ago I rooted my S2 Galaxy Tab (T719) and now I would like to upgrade from Android 6.0.1 to Android version to 7 or 8. I have googled for instructions on how to upgrade a rooted S2 Tab but did not find anything useful (most info is on OTA upgrades which no longer works on rooted devices). Could someone please post step-by-step instructions (please bear in mind that I only ever deal with this kind of thing once every 2-3 years so I do not have much experience). I have TWRP v 3.0.2 installed (do I need to update this as well?) and the tablet is not encrypted (so hopefully I won't have to wipe the system partition and re-install all the app?!?). Thanks.
I also noticed that there is now a huge variety of ROMs out there. How can one know which ones are trustworthy? The main reason I rooted the tablet was to be able to increase privacy (control app permissions with XPrivacy). So I do not want to install some custom ROM that maybe contains spyware or other compromising features. Any advice on this would be greatly appreciated. Given my motivation (privacy) for rooting, would it maybe be better to go back to Stock ROMs (i.e. non rooted) and simply control web access via netguard (by preventing net access for some apps, they may still spy on my contacts, location, or email but cannot phone home to transmit the information)? At least I would still get OTA updates because being excluded from the OTA channel also poses a security risk in itself I suppose. Ok so any advice would be appreciated.
Thank you in advance!
There is no official Android 8 for our device. If you want 8 or 9 you have to install a custom ROM like LuK1337's LineageOS port. It is as safe as LineageOS is by itself on any device. Only problem you might have then is that calling is not possible anymore for now, but LTE works. If you want to use LOS, you HAVE to format data because it's not compatible at all. If you wanna stay on official Android you might keep it. Installing is done by flashing the official firmware with the correct country code over Odin. This will remove TWRP at first so you have to reflash it by Odin afterwards. For firmware download I always use: https://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647 and Odin is found by google. If you wanna got the way to LOS you have to do all the steps I mentioned before too anyways to have a recent Modem firmware and bootloader. In that case you just have to flash LOS and OpenGAPPS by TWRP and delete /data aka Factory reset.
Regardless what you do, after ODIN is done, you HAVE TO boot into TWRP immediately to keep it from being removed by official firmware. While you are in there anyways you can install magisk to keep it from encrypting /data
Many thanks emuandco. So I guess I will stick with the Android 7 as I do not want to reformat the tablet and reinstall all the apps. I have started to download the Android 7 stock ROM, but it is taking quite long so in the meantime just to confirm, the steps to follow are:
1- use odin to flash the stock ROM (no steps required prior to this? I simply overwrite the existing ROM? I suppose that I will loose root then and need to re-root the device using the standard procedure as explained here: http://www.samsungsfour.com/tutoria...nougat-7-0-using-cf-auto-root-all-models.html ?)
2- use odin to flash TWRP (I will need the newest version I guess and cannot use the same as for Android 6?)
3- boot into recovery mode to ensure that TWRP does not get overwritten
4- done
Is this correct? Do I then need to reinstall Xposed, SuperSU and Xprivacy or will they be preserved?
Thanks again!
P.S.: BTW, I also found these instructions: https://forum.xda-developers.com/tab-s2/development/twrp-3-0-2-1-galaxy-tab-s22016-sm-t713-t3390627 which are slightly different from http://www.samsungsfour.com/tutoria...nougat-7-0-using-cf-auto-root-all-models.html and require a wipe of the data partition. Does this mean that for an update to Android 7 I definitely do need to wipe the data partition? If this is the case then this would be a major disadvantage of rooting in the first place and maybe I simply flash the stock ROM and do not root at all but go the "netguard" route as mentioned in my original message?
I never used the official Firmware that much. Fist thing I did was going on LuK1337's nerves to get a port of LOS for it up and running So no clue if Samsung manages to keep /data but I guess so. Yeah, looks fine what you list there. You COMPLETELY overwrite ANY modification in kernel or /system, so reflash your mods and root (Magisk). I always recommend to uase the MOST recent TWRP. (https://dl.twrp.me/gts28velte/ should be it in your case).
Ah and looking at your manuals... Check OEM unlock just to be rather safe than sorry if things go mad.
