Hi,
I am very new to this android world so my queries might feel stupid. Actually i m here after 3 years and that is very long period in this world. I know about rooting(super Su), bootloader and recovery (stock,CM and TWRP) . Recently read about Magisk and got some queries. Hope you will help me out. These are not device specific but need to learn.
What i read/study i found these readings...
1. Magisk roots device systemlessly (does not touch system partition) so one can get OTA updates easily.
2.To install and run Magisk one needs to unlock the bootloader .
3.(Device Specific) My redmi MI Flash tool says,If you unlock the bootloader , you wont get OTA updates.
4.I have previously rooted my galaxy Y and uninstalled system apps. If i delete sys apps from magisk,still can we say that we are not touching system.
So all statements are true? or some? or none ?
Here my device is redmi 3s (6.0.1- MIUI 9.6.1.0 Global Stable).All these queries are just in relation to OTA system updates. Nothing related to warranty.
Thanking You
Yes.
Yes.
Don't know about Xiaomi, but I've never had issues with OTA on a device with an unlocked bootloader (I've mainly used different Google and Oneplus devices). Someone with a Xiaomi is gonna have to chime in on this one.
As long as you use Magisk's debloating feature of replacing files or directories with empty ones, you're good. The actual /system partition won't be touched. Use a module like the Debloater module by @veez21, or make a debloater module yourself.

Ahh, Thank You.
You get OTA system updates for your STOCK ROM ?

Yes. But, having both Magisk and a custom recovery (an OTA won't install with a modified boot image and a custom recovery installed) I always find it easier to download the update and flash it manually. But, like I said, I have no idea if this is true for Xiaomi.
1. Ok. i also heared that when you update your device,you lose root...not true ? Or you need to root again ?
2.In normal stock device,we get update notification and we downlaod then restart (as per convenience)device to update.
If i remove some system apps from my rooted device and unroot the device,manage to get stock recovery back ,will the OTA update system treat my device as Stock-untouched? And install updates just as stock device will do ?
3. Is boot.img and bootloader are same things? Coz i read that for re locking boot loader you need to flash boot.img from stock software. (But Some procedures just use fastboot and relock oem command-they wont use boot.img,dont know why )
I read that unrooting,restoring stock recovery and locking bootloader again is more difficult/complicated than the rooting procedure
Some one should come up with solution just like Windows Restore .If you want to go back to everything STOCK,just use that feature same as done to Restore Windows in its previous state.
Any update that also updates the boot image (which means pretty much all) will remove root. But, that's just a simple case of reflashing Magisk right after applying the update.
If you've touched /system in any way, removing system apps or even just mounting the /system partition read-write, an OTA will fail. To be able update with an OTA your /system and /vendor partitions need to be untouched and you need to have the stock boot image and stock recovery installed. If your device doesn't conform to this the OTA will fail.
Boot image and bootloader are not the same thing. That you can read up on all over the internet, so I won't go into details. If you have done any kind of modifications on your device, I suggest you leave your bootloader unlocked. It's to easy to mess things up otherwise.
Going back to full stock is usually just a matter of flashing a full factory image/firmware package/stock ROM. Quite easy... Of course, some manufacturers make it harder than others.

Ok. As you say the two are different , but can you explain in simple words (terms) that how they both are related/linked/connected? Coz as i read some forums/posts i get to read
1. To relock/lock bootloader you need to flash boot.img which suggests these (terms) are linked/connected.
2. but same time some forums/post suggest no img file flashing but just a fastboot command(s) to relock bootloader. In this case it seems they are not linked/connected.
And if the above 2 statements are true and device specific then how the bootloader and boot image are linked and not linked in diff devices? what changes are made so that in some cases these are linked and in some not
Sorry for asking too much. But you were really very kind to help me out.Thank you once again
I'm not 100% accurate (and someone will hopefully come I'm and correct me if needed), but basically the bootloader checks that everything is alright and then starts up your device. After that the boot image (ramdisk and kernel) takes over. Ramdisk basically makes sure all the partitions are mounted, and the kernel is exactly what it sounds like. The core of the OS, making sure that everything is working as it should.
This is of course a huge over-simplification, so if you want more you'll have to search around (and there are tons of resources around the web).
The main reason I can think of right at the moment for wanting to flash a boot image before locking the bootloader is that it's generally a good idea to have your device fully stock and functional before doing so. After you've locked the bootloader there might not be any going back if things start acting up and you could end up with a nice paperweight.
Questions are good. That's how you learn. I do believe that you'd be much better of searching around the internet for your answers. They've been put out there many, many times.
Ok.Thank you very much.I will learn more ...
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.

Hello,
I bought a 9T Pro in Europe for my wife and until it arrives I'm trying to research and come up with a low effort process of keeping the stock ROM up to date and rooted for her. I'm confident in manually installing and updating custom ROMs, rooting and dealing with custom ROM issues, but she is not. Therefore I thought the best thing is to use the stock ROM - not custom - since it may be the most stable experience and for me to update and re-root it for her regularly. root is mandatory because we need AdAway and other things. As I understand it, as soon as we unlock and root the phone, OTA updates for stock are impossible and maybe even dangerous. I've tried researching here but am bit struggling to come up with the right infos and I'd be glad for any advice.
Of course I have seen the great thread about unlocking, rooting, etc, but It seems that that deals with non-standard Chinese firmware pre-installed, which is probably not the case on our device. Since it's bought in Europe, I think it will probably come with some Global or EU ROM. And it doesn't answer some of my other questions.
So far my idea is roughly like this:
Phone arrives
Immediately update it via built-in OTA to latest official stock ROM
Unlock, install TWRP, root with Magisk
Use the phone
Whenever a new stock ROM comes out, download it from XDA
Flash new ROM in TWRP and root again with Magisk
Repeat 4-6 as new stock ROM versions are released
Of course regularly backup with Titanium Backup and TWRP
First of all, would this work or did I misunderstand something fundamental?
How does low level firmware / modem update come into play? Would that be included in the stock ROM packages I find here? Or do I need to manually update that separately? How do I know when I have to, since there is no custom ROM maintainer telling me when it's needed?
Is there an easier way of doing this? This process requires me to regularly check for a new stock ROM, then borrow the phone from the wife for some time to backup, update, re-root and so on. Not that convenient but it would work if there is no better way.
Sorry for the long post, but I'd be very thankful for any advice or ideas. I did quite some research, but if all this info is already available and I missed it, my sincere apologies. It's a lot of info about a new device to take in. :silly:

I didn't keep stock MIUI long enough to know definite answers, but from what I remember, this is my understanding.
OTA will still work and shouldn't cause any issues, just that you will lose TWRP and root whenever you do this.
The steps you give are the normal way to update with TWRP and root.
However, OrangeFox recovery (a heavily modified version of TWRP) is often used instead of TWRP in this circumstance. It is built specifically for MIUI devices and with a little bit of work, I believe that it is able to survive OTA updates. Have another dig around for OrangeFox in this forum section and hopefully you'll find details on how to set it up so that you can still take OTA updates.
Edit:
Found this guide https://forum.xda-developers.com/k2...efox-recovery-mi-9t-pro-t3980579/post80480669
It seems OrangeFox it's a bit hit and miss.
Also Xiaomi.eu ROMs are another alternative to look into.

Wow, that's a lot of helpful info, thanks a lot for pointing me into these directions. I will definitely look into Xiaomi.eu, I that sounds promising!
Get phone. Apply for unlock. Unlock.
You can use my guide bit.do/raphaelguide
Use orangefox 10.8 use magisk.
You can flash eu ROM. Stable version. From xiaomi.eu
Eu rom installs official twrp after install. You are familiar with that
Once you have eu ROM ( same as stock, better performance, minimal bloat, no ads, no tracking)
Eu ROMs gets OTA, keeps root. This is exactly what you want. Just press update in settings as normal ota. It'll do normal ota update by itself, no titanium, migrate hassle.
Join telegram group if you want or on me for any help.

Amazing, I have taken a look at Xiaomi.eu already and decided to try that. But what you're saying sounds even much better than what I expected. Thank you very much too, I will definitely go that route.
Hi! I have been racking my brain at trying to figure out how to rollback to stock firmware because I have a faulty camera module so I cant take pictures of x1 zoom without it becoming a blurry mess.
The device is under warranty and they told me that I can send it in. However right now I have the latest xiaomi.eu rom weekly rom and I am under the assumption that you have to go back to stock before sending it in for warranty.
I have downloaded the latest version of Miflash 20220507 and downloaded the latest stock rom I could find but it ended up giving a error message. I tried the other method of using TWRP but that also ended in error, I have tried using both the global and EEA rom.
The only guides I can find says to use Miflash and find the approiate rom so not much guidance there.
Try searching that error code you've got in miflash
Which version of the rom should I apply (From Sweden) Global or EEA?
Been using this website for the Stock ROM - https://xiaomifirmwareupdater.com/miui/venus/
Thanks for taking your time to reply so far!

I'm not on MI 11 but Mi 11 Lite 5G NE, but method is the same
Install the following app to download the correct FASTBOOT (tgz) ROM type for your phone - choose Global or EEA (India, etc, as you wish):
MIUI Downloader - Apps on Google Play
MIUI upgrade app for Mi users.
play.google.com
To uncompress, you first need to un-gzip and then to un-tar
Copy the uncompressed content to your adb/fastboot folder on the PC
You will see three BAT scripts (for Linux users SH scripts)
You need to use the following (to flash and FORMAT, but WITHOUT relocking Bootloader):
flash_all.bat
(read the rest before flashing)
Why not relocking BL - bcs, if anything goes wrong and you already relock BL, you will have a bricked phone that requires paid EDL support to fix (not covered by warranty)
You can relock later:
fastboot oem lock
when you make sure that stock ROM works correctly - if you really want so (not sure if relocking is required for warranty).
As long as BL is not locked, you still have chances to flash again or different ROM until you get everything ok
Hence open thar bat file in Notepad and check its last lines, that script does not relock BL (before it's last command to reboot the phone) - if the script wants to relock, delete that line
Also, in the Notepad inspect first three or four lines of the script. They are about anti-rollback. Since you are coming back from Xiaomi.eu, might be that anti-rollback will block you to proceed with flashing
Carefully inspect those first three or four first lines (you don't need to be a programmer to understand), and remove them
(I cannot give you more precise details, I would have to download again 3.5 GB tgz file, uncompress, etc - I WON'T do that again, when I needed for myself I did and then cleaned almost 20 GB from my PC)
Then run that edited BAT script. It will flash the full stock ROM (without bothering about anti-rollback), and will not relock your BL. Reboot (if script does not automatically) and configure your 'new' stock
Which is mandatory to be under warranty - Global or EEA - you said to pick as you wish but I am just making sure its all in order before going forward - I will start downloading it now and trying it out! Thanks for your help thus far.

How do I know how/where did you buy your phone and what is mandatory for your warranty?
Usually, it would make sense that you put the same, Global or EEA that was on your phone when you bought. You should know what did you have
My apologies for not mentioning it, but its bought in Sweden, (Europe), and reading the warranty rules; it says no modifications allowed to the phone, but I am not reading anything about software. Xiaomi.EU did, however, mention that you should flash stock. I cant remember what was on the device originally as I did a fastboot flash.
Having EU means you've unlocked your bootloader. It shouldn't be a big deal tho, you will be able to get it repaired under warranty because Xiaomi doesn't really go into details of unlocked bootloader.
Please post the error code/screenshots from MiFlash for the errors you faced.
Also, it's pretty easy to figure out whether you had a Chinese or global variant. If the box and all the info on it was English, you can flash any of the Global versions (EEA, MI, IN, etc)
It doesn't matter really as long as your phone was a Global variant and not a Chinese one.
Please answer my all questions properly .
how to unroot redmi note 9 but there are some conditions will it still work though -:
I have an unlocked bootloader
I have an custom recovery unofficial twrp dimenzino recovery like something it's name
__________
I went to an local shop they were saying if your phone got bricked it's your responsibility and were charging me ₹800 .. Is it true about bricking issue ?
___________
When I was doing it from magisk app it was giving insufficient partition size error . Can i have a reason for that and can it be unrooted in this condition?
____________
And now please tell the things in order to do like
First i have to remove custom recovery and tell the way ? Or it will be removed by flashing boot.img .
I have installed miui 13 so going to 12.5 will downgrade Android version ? I have listened that downgrading Android can brick pls confirm or i will stay to miui 13 only
Then how to lock bootloader after unrooting
And i know about data backup but it will reset my device ?
Where will I get original boot.img for my device provide link if possible Redmi note 9 (Merlin) Indian Varient.
What software will be used in pc and how to operate tutorial if possible .
Please reply all the questions..
Am regretting why I rooted without having zero knowledge please help me
Unfortunately, downgrading from MIUI 13 (A12) to MIUI 12 (A10/11) is/may not (be) possible because of the security patches and MIUI's anti-rollback feature. I could only downgrade my MIUI 12 back to 11 as it was still Android 10. You can unroot your device by flashing the MIUI using the Mi Flash. Just remember to choose a lock option and not Wipe Internal storage as you may lose the IMEI numbers and the whole NVRAM. I can't verify if it will work for you. It worked on my Redmi Note 9 Global (EEA). Also, I'm not sure about the MIUI and Android vendor downgrading as I've seen many people hard bricking their devices by forcing and bypassing the MIUI Recovery "Can't downgrade this MIUI version" error. Maybe I'm wrong in something. Feel free to criticize and fix my mistakes. Unlocking a bootloader and flashing a custom ROM is considered to be "irreversible and permanent" as the user's goal may be to get rid of the MIUI and full control of the phone/OS.

Thanks for the response but can i have talk with you personally am having zero knowledge about it ok I want to remain to A13 global miui in Indian Varient and where will I find boot.img and flashing process via mi flash tool and what Is lock option how to enable it and not wipe my data. Pls tell. Am not sure what am I saying but custom recovery which i have and the boot.img will remove that custom recovery and Unroot my device and i need firmware file which is like 30mb and flash the folder containing files ?

Lock option locks the bootloader, like it came out of box. You can find the boot.img file in the ROM's package or in the MIUI's folder called Images. Lock option needs to wipe the device as it's enabling back the security layers to the memory to prevent injecting bad codes into the device. Unlocking disables it on the other side, that's why a full wipe is necessary.
