[Q] does rooting modify the original firmware?

Hi,
I plan to root a HTC Desire C only for sim unlocking it. So far I am pleased with the original firmware (ICS 4.0) - after disabling some apps the phone runs fast and smooth.
The question is: does rooting modify the original OS in such a way that instabilities may occur?
Thanks.

Rooting itself doesn't modify anything besides installing an app called Superuser.
You deleting/disabling apps that were not meant to be disabled does.

Thank you for the related link. Helpful.
As I like, for the moment, to stick to the original firmware (to me, it is the most stable among all avalable roms for HTC Desire C), I still have two more questions:
- will the rooting stop the handset from receiving official updates?
- assume I root the handset and install cwm recovery and backup the current rom.
if ever I like to restore this backup, I will need to flash a kernel boot.img.
can I extract the kernel related to my current firmware so I can flash it after I restore?
Thanks.

- As far as I know, you can receive updates but you cannot apply them. It will show in the notifications "Software Update, Click to download" when you download it, it will reboot to recovery and stop there. Again, I'm not 100% sure about this but this happened to me once.
- If you flash a custom kernel like Prometheus Kernel, then you will have to flash the stock boot.img if you wanna go back to stock completely. But if you never changed your kernel from stock, then you don't need to do anything. I have provided the link to stock kernel and stock recovery as well, in the Index thread. (Link in my signature)
PS - As far as Custom ROMs go, you should try the Sense Roms. All of them are based on the stock ROM so all of them are completely stable. You can always put the 'Stock theme' on these roms to make them look like the Stock ROM and you will end up with a ROM that looks exactly like Stock but performs much better and has increased functionality
Hope this was helpful. I'll be glad to answer any further questions.

It will not definitely modify your system it will add a folder to your system to access the system... and also it adds app called Superuser or SuperSU ....
Features of Rooting:
Android rooting is the process of allowing users of smartphones, tablets, and other devices running the Android mobile operating system to attain privileged control (known as "root access") within Android's subsystem.
Rooting is often performed with the goal of overcoming limitations that carriers and hardware manufacturers put on some devices, resulting in the ability to alter or replace system applications and settings, run specialized apps that require administrator-level permissions, or perform other operations that are otherwise inaccessible to a normal Android user. On Android, rooting can also facilitate the complete removal and replacement of the device's operating system, usually with a more recent release of its current operating system. Most of the time,[citation needed] rooting a device voids its warranty.

[Q] Am I ready to install CM11 M10 Snapshot???

I have done most of the initial steps required to install CM11 but still I want to conform if I am going in the right path...
Model : Xperia SP C5302
Built number : 12.1.A.1.207 (Stock)
Kernel version : 3.4.0 (July 8 2014)
I have done the following things:
- Rooted using Towelroot (Verified root using a few root checking apps)
- Installed SuperSU (Chainfire) and BusyBox
- Installed CWM 4.4.1
And have not done the following:
- Yet to Unlock Bootloader
- Did not flash any Kernel
So I have a few Questions
Question 1:
Unlocking the Bootloader will lead to permanent loss of DRM keys... So will I be able to access Bravia Engine by any means after installing CM11???
Question 2:
Is it necessary to flash a kernel before installing CM11???
Question 3:
Is it safe to install CM11 by booting in Recovery mode or Flashboot mode (or whatever they call that, in which we do not need the help of PC) or using flashtool in PC is much safer and better???
Question 4:
Is there anything else for Me to do other than what I have already done (all those I have mentioned)???
Question 5:
There are a lot of Bootloop complaints about the recently released CM11 M10 Snapshot... So is it safe to install it or is it better to go with Nighties??? Is Nighties Stable (around)???
Question 6:
Is there any method to bring back the use of the Illumination bar in the mobile as a visualizer in Music n Photos app after Installing CM11???
Question 7:
In case I mess up, is what is the method to return to stock firmware (and what should I do now, i.e. before Unlocking Bootloader)???
If not all, please help Me clear at least some of My doubts
And if possible, It will be great if You give a complete tutorial (video or post) form a stock, unrooted, locked mobile to a mobile running a custom ROM...
Thank You all a Lot :victory:​

First I will suggest you to leave your Bootloader locked and just install Paranoid or PAC ROMs.
1. Yes, you will lose your DRM Keys. No you wont be able to.
2. It's good to flash latest .207 kernel before/after you install the ROM (if your bl is locked).
3. Just install it from CWM/TWRP
4. Root→install recovery→wipe data/cache etc.→install ROM→install GAPS→flash kernel→reboot→you Gucci
5. Your phone can always explode if you're dumb enough or you just don't like to read. (as I said PAC or Paranoid are better options than CM11)
6. Not really sure.
7. If you have your bl locked then just put your phone in flashmode and flash stock .ftf with flashtool. If not relock your bootloader then do the same.
So, if you ask me go for PAC ROM and locked bootloader. I think it's the best ROM so far for our device. I'm with Paranoid and it's quite Gucci as well, everything works like a charm, the ROM is fast and stable. I'm only suggesting you to install Greenify and DS Battery Saver Xposed Modules cause the battery isn't as good as the stock one.
As for tutorial, just read the guide in the thread. It's pretty simple and straight forward. You have to be really dumb to mess up five simple steps.
Good luck!

For Q6, it is possible to use the illumination lights via U-Disco, here.
You can unlock your bootloader and use custom kernels, but I personally recommend staying away from that and using locked bootloader roms, there are many good ones. The risk (hardbrick :crying: ) is not worth it-if you mess it up.

Yes you can ! The LBL tag means locked bootloader (opposed to UB or UBL for unlocked). You can flash any ROM that has it but just check the instructions in op for any ROM specific recommendation.

Is there any basic disadvantage of flashing ROMs on a locked bootloader(like some features not working?) or is the similar to unlocked bootloader roms?

[SOLVED] How to fix the TW Oreo battery calibration issue.

so for some reason upgrading to oreo really messes up the battery calibration for me. at first, everything will be fine, but after a few reboots and using the phone, the battery percentage is everywhere. I'll plug my phone to charge and the percentage will rise as if it were seconds. I love oreo to bits, and I prefer it over nougat obviously. I used Odin to flash a stock rom, and still it's happening. anyone know what we can do to fix this? I know others here have the same problem.
EDIT (09/03/2019):
some people have mentioned ways to try and fix the problem, so I decided to make this a thread to try and find a solution to the calibration issue.
How can I participate?
You can participate by (briefly):
*submitting a solution you have found
*submitting an idea that may potentially work
*testing the fixes or ideas submitted
What else?
*solutions that are submitted are to be tested and confirmed if they work or not.
*ideas can also be tested, but at your own risk. make sure to make a backup of your current rom and storage if you don't want to lose anything.
*also submit what model you have (unless this applies only to the G610F model - we cant tell).
we can do this. I am tired of android nougat (android N doesn't have this issue).
EDIT (14/04/2019)
so, now that our phone actually recieved OneUi, theres no point for this thread android Pie doesn't have this problem, which is fantastic. thanks for those who contributed!
ill keep this thread around in case there are some bois out there who still prefer oreo for whatever odd reason.
but honestly tho, oneui is perfect.
PEACE!!
EDIT 13/05/2019
SOLVED!! (FINALLY)
right now im running oreosama rom, with no issues, no problems at all - i have (accidentally) found the solution to this battery problem!
the solution is very simple - download a stock oreo rom from sammobile or updato, and then flash its bootloader with odin. the battery calibration issue occurs cause the bootloader is still based on nougat. that issue goes away once you upgrade.
there you go folks - happy oreo flashing!!

I have the same problem after an OTA update.

officially from samsung?

Try to use Battery Calibration app on CHPlay of SuperThomasLab, read instruction and follow that, i am in TW Oreo and my battery is OK although it stills rarely mess up

I have this problem and I don't know why. I have Android 8.1 official

I had the same problem but .. its gone after flashing oreosama rom and in other TW roms that supports USSD CODES (including the stock) I used *#0228# and it worked everything was ok

Can you give more details?

so I updated the post. anyways, I tried your idea. I downloaded oreosama and used the ussd code. I thought everything was fixed, then suddenly it gave the usual problems. so your solution did not really work. is there any way we could like port the nougat battery files over to oreo?

If you try to delete battery.bin?
Maybe it would help you.

Drain to 0% and charge your phone to 100%. While plugged in, dial *#0228# and press 'Quick Start'. It would be better if you are on stock ROM. Do it 1 or 2 times and you are good to go. Works like charm for me.

do i dial the ussd code once the phone has reached 100%? how do i know if theres a battery calibration issue?

It worked on my phone.

I think you need to replace the battery with new one

Before doing make sure battery is at 100%
1. Go to root/data/system.
2. Delete all the files which have a name that starts with battery.
3. Delete the Dropbox folder.
4. Reboot to TWRP.
5. Go to Wipe -> Advanced Wipe. Choose dalvik and cache partitions and then wipe them.
6. Reboot and check.
For TWRP and root users ..

op post edit~

guys, ive finally fixed the problem. check the OP to see how!

Help, all of your methods are not work on my phone. My phone is charged too quickly to 100% and after restart the battery is draining to 10%.

How do I upgrade from an rooted and unencrypted OOS 5.0.4 to OOS 9.0.5?

So recently I've been thinking of upgrading my phone from Oreo to Pie now that it is available and has had a few updates.
Now I haven't updated my phone in a while. The last time was around the summer of 2018. The OxygenOS version my 3T currently is running is 5.0.4 and my TWRP is on version 3.2.3-0.
A while back I was using the custom ROM 'FreedomOS' (for anyone that still remembers) but that ROM hit it's EOL point last year.
After FreedomOS went EOL I switched to stock ROM following this guide to stay decrypted: https://forum.xda-developers.com/oneplus-3t/how-to/disable-dm-verity-force-encryption-op3t-t3688748
Since I switched back to stock I haven't touched the system or recovery at all besides updating Magisk now and then.
Now the question I'm having is how do I update my phone to the latest Pie version of OxygenOS? Which is version 9.0.5 as of writing this post.
Preferably I would like to upgrade with a dirty flash to keep my data (if I run into issues after I'll clean flash) and I also want to stay dencrypted and have Magisk as root.

For your own sakes don't do that. You probably won't be happy unless you want to update to have bigger numer in info screen. (Well if you would like to update to have bigger number in info screen I would suggest editing some conf file to achieve that.)

it's here all the the time, just follow the guide
https://forum.xda-developers.com/oneplus-3t/how-to/official-oxygenos-5-0-1-android-8-0-t3728119

First of all, both of you thanks for the replies.

Is the update that bad? If so, what makes Pie so much worse when comparing it to Oreo?

I've read through the thread a bit and notices this: "Important Note: If your device’s Bootloader is Unlocked, then installing this firmware will factory reset your phone as this is a firmware upgrade. All your personal data and app data will be wiped clean! So backup before flashing!"
Does this mean it will actually reset the entire phone and will wipe all of my apps and files? Is there not a way to dirty flash this new version without losing my apps and such?
Now also in the "Custom ROM" part it says the following: "3. Format Data partition - system will be encrypted (this is a must else system will not boot the new Android version)"
As my device is unencrypted at the moment do I need to let it encrypt for OOS 9 to actually boot up? Or can I just follow the steps in this guide and follow procedure 1 to stay unencrypted? https://forum.xda-developers.com/oneplus-3t/how-to/dm-verity-disable-oxygen-os-t3922324

In simple words phone is slower and hotter. Battery isn't better too (battery life for me was decreased from 5 to 3, 3.5 hours screen on time). You can find more on Oneplus forums.

i personally would suggest you to stay on oreo or jump to pie custom roms, just skip the oos 9.0.5..
the only thing that really fast and smooth just the face unlock feature :laugh:
as far as i know when you flashed stock oos your data will always be (re)encrypted, unless you do the firmware's patch things like you did before.
jumping (upgrade) from diff. android version it's better to do a clean flash (4 wipes, exclude int. storage will be saved)...and it's mandatory required (from stock to any custom roms). except when you forced to format data you'll lost all data in your phone, for sure.
and if you want to stay unencrypted and disable dm verity for good, it's better to do all that stuffs while on stock oos before you jump onto custom roms.
for more details and assistance i suggest you post on the main thread.

It is slow, slow, slow...

Hi guys,
I'm a bit concerned about my mi8. Since several weeks now the phone is getting so slow to boot, even into recovery mode !
For exemple, today before starting to see the havoc logo spinning I count more than 20 spins. Months ago it took only 5 or 6, 2 weeks ago : more than 8... Etc.
When phone is started first apps tha usualy open really fast (Viper4fx, gsam battery monitor, magisk notifications) are so slow to open. Some other apps same thing the moment I open them.
What do you think about that ? At first I thought my battery is dead. It charges as fast as usual. Discharging is like before I'd way. Not worst for sure So I hope Its nor that.
I'm using battery charge limit (the app, nor from havoc sertings) to stop at 81% and charge it always when the minimum reaches 40%. So for battery life I think I'm doing things well.
I'm still on pie. Please, see the attached picture to look at my version.
I'm wondering what could cause this big issue.
I'm used my make lot of backups with twrp 3.3.1-1. Sometimes 2 per days, sometimes none in 2 or 3 days and so from the day I unlocked the phone and installed my first and only rom : havoc. Sure I installed several updates but no other ROM and I stopped updating it cause it worked really as I expect it should. So...
Also, making twrp backups are Soooo slow. Generaly it tooks depending of the size, between 90 sec and 140. Now it takes more than 6 min !!
So before doing a last backup and do anything I wanted to ask what you all think about that before doing a clean install update/upgrade.
Do you think it worth the try ?
I tried to clear caches (both) in twrp. Nothing :/
I'm afraid I killed my phone memory or battery. Don't really know.
Last thing, maybe an important one but don't know why it would... I installed notify & fitness and sleep as Android for my mi band 4 and I noticed my phone getting slow during this period. About N&F it was on 12.27.2019.
The firmware was updated way after that issue... And of course I cleaned all app caches manualy, not using some weird app to do the job.
Sorry me for this long SOS, and please forgive my bad english. I'm starting to being crazy. OK, the phone works but oooh boy, Its slow.
Cheers

Your rom software is out of date. if you truly want the best experience on a daily basis. There is no doubt in my mind that Xiaomi.EU is still the absolute best experience overall.
It is light years better than the Global stock Rom, all of the bloat has been removed and it has some of the Pixel AOSP features integrated into the Rom. but yes it's still miui. For me that is a good thing because I am a fan. It sounds like you have never tried Xiaomi.EU so give it a shot. I guarantee, that if you keep it installed for a few days, you will not want anything else unless you are just bored. Wait until the new update comes out, it should be late today or tomorrow. by the way, you will average about 7.5 -8.5 hours SOT.
On the other hand, if you are content with Havoc, then migrate to the latest, Its pretty great but the battery SOT time is bad right at 4 hours. This can be improved by changing the kernel. I tested the LawRun_x5.0-60hz kernel and it improves SOT to 5.5 hours, and the OS gennnerally runs better. Other Roms are also good, but lack the abundance of features that Havoc has. A comparable heavily feature rich rom is CRDroid.
If you want to stay on your current rom, then clean your caches, and at least upgrade the kernel. That alone may be enough to improve your recent performance. i dont think you phone is going bad. You likely just have some corruption, or too many processes running in the background.

@tsongming Hi and cheers for replying.
To start, I forget to mention that I'm using a global version.
That being said, I did clean all caches including from all my apps. Manualy of course.
I did use Xiaomi MIUI for very long time. Since I got my first Redmi Note 4. As you well said, I did switch to custom ROMs for what you said.
Regarding SOT... And the reason why I didn't update anything on my Mi8 its because with this version of havoc and this kernel. Gsam bat monitor tells me now : 9h41 (5h58 Max) and before my issue it was 11h !
So, to answer you : before asking here I also trying to update the Rev kernel but lot of things didn't work anymore. Like unlock the phone with my fingers and I think its pretty much normal as Havoc as evolved so kernel did the same and is not compatible with older version I think. At least, mine...
Honestly I tried lot of things to make my havoc super speed, smooth with a great battery and I was happy with that
I do hope I answered to all your questions.
I don't know what to do cause I'm not 100% sure that starting from clean MIUI or custom rom will fix it. What if not ? I'll "forced" to reinstall "everything" (I'm aware of backup apps but dont wanna use them) even if I saved all important stuffs
And if I badly revert to the last MIUI (I never reinstalled MIUI after a custom ROM. I know there is good tuto, but...) I could break it and I'll loose everything. For now it works, slowly OK ^^' but I rather that than taking a risk and found what is the cause of my problem.

I don't know what to do cause I'm not 100% sure that starting from clean MIUI or custom rom will fix it. What if not ? I'll "forced" to reinstall "everything" (I'm aware of backup apps but dont wanna use them) even if I saved all important stuffs
And if I badly revert to the last MIUI (I never reinstalled MIUI after a custom ROM. I know there is good tuto, but...) I could break it and I'll loose everything. For now it works, slowly OK ^^' but I rather that than taking a risk and found what is the cause of my problem.

The current version of Havoc already uses the Revolution kernel, and its part of the current problem so use something else. The Law kernel that I mentioned is extremely good. but so are the others latest release such as Mipa and Twisted. and no fingerprint issues with these kernels.
As a longtime user you do know that anytime you switch the kernel that you should remove all passkeys, screenlocks, face unlock etc.? This could explain the slowness, you have encryption issues.
Android 10 is much improved over pie, except for the battery 11 hours SOT is unheard of on Android 10. Except for 1 guy claiming 11 hours on the ION rom. I tried the rom and it is good. but I am only getting 7 hours Sot, and the Rom is like Lineage, just the basics. No fingerprint issues.
You truly need a full clean install, including formatting storage. just backup your files first.
Xiaomi Miui? Did you mean Xiaomi.EU? if not Xiaomi.EU , then you really should try it, you wouldn't know from a past experience. This is Miui 11 on Android 10 and its flawless.

thx again @tsongming
Yep, I note all what you said to me. But to be honest last year anytime I switched from kernels to kernels I never had to reset screenlock etc. Last year cause as I said once I found the kernel which suits me I stuck with it.
So I can state its note related to that cause I didn't change it since month trust me, just tried the last kernel one or week ago to be sure if it was the cause or not. Just installed and uninstalled apps since.
look at this screenshot you'll see what I meant about SOT which was better month ago. :/ Maybe I didn't explain well...
I'm not against trying any roms including xiaomi.eu perhaps (I do have links for this I think but any link is appreciated just in case. I just download the lastest stable 11 from xiaomi.eu if its what you have in mind) but I want to be sure if it'll fix what I'm facing. You know ?
I'm afraid that doing a clean install with any rom won't fix my beautiful Mi8 ^^

You posted a question asking for help, but then you dont want to try anything because you tried things before. Yes, its true that Magisk is sometimes persistent, but it depends on the release. it is safer to remove the passkeys.
But if you really think about it, what would cause the phone to cool down, ignore the battery stats especially from Gsam it's often very wrong, I use it too, for years and in your case you are getting good SOT because you have a zero % for the phone. It's almost like a Sim card isn't installed? Every rom will provide extremely fantastic SOT when a sim card isn't being used. If you have an active sim card then something is wrong with the monitoring because Gsam is showing 0%, it should show something even if you havent made a phone call for days.
Do whatever you want it's your phone:
I still think that you have encryption or corruption issues and its bad enough for your to make a post about it. FYI : The battery dying doesnt slow down the phone. Yes, some stock roms, notably Apple intentionally by choice changed the kernel core settings automatically on aging batteries. Hence the huge controversy a couple of years ago, that isn't happening to you.
A dying battery doesn't slow down the phone, evn cold solder joints do not slow down the phone, they keep a phone from booting to system and to recovery. The only thing left is corruption or thermals, which on this phone good luck editing thermals because they are mostly encrypted. The remaining possibility is corruption, post your log files and lets see what's actually going on.
Again, what would slow down your phone even in recovery?
It's always thermals, or corruption. Slow to start up, even in recovery.: We can rule out thermals unless your battery temp or cores temps are extremely high. This leaves corruption. if its slow while booted into the system, then you may have apps or processes crashing and you are not aware of it. If that is true, then eventually the phone may stop booting up altogether. If its thermals causing overheating you should truly resolve this issue immediately before actual heat damage occurs. Did you ever flash display refresh rate mods? If so your DTBO partition could be the issue....corruption.
Use this program to provide an app list : https://play.google.com/store/apps/details?id=de.onyxbits.listmyapps ( Weed out any unknown programs that you may not realise are installed. Post the list along with complete logs. Once you see these crashes, that I am sure the logs will show: Do as I suggested earlier: wipe and "format" your phone. Then later use best practices and remove passwords before changing kernels

Cheers. I'll try what you suggest.
I might have some questions in the future regarding format and some other things.
Never flashes display refresh rate and never noticed any overheat issue on my phone.
Sure, I'll do something like you said as soon as possible.
PS : you said "before remove passwords". You mean in the parameters of the phone like schema/diagram, pin, etc ?
Cheers

You could remove password under data/system/locksettings.bin But it's better to just go the settings//security/ *.* < remove whatever you have setup : prints and face unlock first before, pattern or pin.
Another good practice for Android 10, should you go there is :
Extract the boot image from the rom
Place it inside the downloads folder.
When ready to flash root, patch to the boot image first, ( this links the existing system binary credentials into the boot image)
Boot to recovery flash boot to boot
Then flash magisk > then boot to system and you will have no issues whatsoever with root.
Afterwards, if you decide to flash different kernel, Magisk is more likely to stay stay persistent.
I hope everything is good from this point forward take care.

@tsongming Thanks for reminding me the locksettings.bin thing because I used it once on my old phone and I forgot that.
Never installed 10 yet. But I take carefuly your advice.

Hello!
Did you fix it? Because it's happening to my Mi 8 too. It's exactly the same issue, the phone takes a long time to boot up, to open apps and even to boot into TWRP

I have that issues on my mi8
I had this problem with me before and I solved it by flashing the last official ROM, Now the problem happened to me again and I do not know what is the reason behind it @tsongming

I recently had some issues with my phone as well. I was able to get my phone back to normal functioning by flashing the latest stable fastboot rom using the flashall.bat method. (dipper_global_images_V11.0.3.0.QEAMIXM_20200118.0000.00_10.0_global)
I kept everything stock for a few days even recovery, to ensure once that everything was back to normal.
Next I flashed the latest OrangeFox beta recovery, and I highly recommend the latest beta build over any other version of Recovery, it will decrypt when official Twrp will not. It is now more up to date than the LR Team version, and all of the bugs have been solved by DarthJabba. In fact, he even added a script to work around poorly designed startup scripts, which are suprisening not consistent between the wide range of custom roms for the Mi8.
Today, I am still using Orange Fox, ( OrangeFox-R10.1_002-Beta-dipper) and the latest stable Magisk. I no longer have freezing, unexpected shutdowns, slow starts, or poor battery life. My issue was without a doubt corruption, and bugs with the mid february version of Xiaomi.EU. The last 2 releases have been solid.

Since this weekend I face the same problem. Every action seems to bit slower than before. And I don't know what I did that resulted in this problem. The last thing I remember I installed was the new Miui12 live backgrounds. But I deleted them again.
I'm on stock since some weeks.
But I don't want to install everything from the beginning again.
Do you know how to solve the problem without wiping everything?
Edit: As I think about it, it seems as if the caching of the apps doesn't work as good as before and the killing of apps is too aggressiv.
But what did affect it?
Edit: I found the solution for my problem.
With Android Battery Historian was able to find the process that made the trouble.
It was the Miui wallpaper carousel app. After deleting it the problems were gone.

Hi guys,
I'm a bit concerned about my mi8. Since several weeks now the phone is getting so slow to boot, even into recovery mode !
For exemple, today before starting to see the havoc logo spinning I count more than 20 spins. Months ago it took only 5 or 6, 2 weeks ago : more than 8... Etc.
When phone is started first apps tha usualy open really fast (Viper4fx, gsam battery monitor, magisk notifications) are so slow to open. Some other apps same thing the moment I open them.

it's a hardware issue and it's going to keep coming back, i spent the last two months trying to resolve it but i gave up.
it seems that UFS chip malfunctions on a lot of F1 and mi8 phones.

Sorry for repling only now guys...
Thx to all who proposed to solve my issue, I will tell you what I did to fix my mi 8.
I did a crystal clean flash :
- downloaded & installed last miui image using miflash
- used "clean all" at the bottom right (be careful to not choose something else like "lock boot loader ")
- then you'll need to flash recovery (twrp), then format data by typing yes. Then copy from where you want your custom rom, flash it flash magisk and boot.
I did this several months from now and my phone is like just new!
No issue at all since.
I guess installing lot of different kernels like I did before must have broken something and hopefully this could help if you dont have more serious issues.
Ps: battery is more than ok and there is no hardware problem.
Thx again to Dexer125 for his help!

I can confirm this.
I have been unrooted on stock for a few months now and have had no problems since then.

Hello, I have the slow issue (Androbench app with poor performances) after several dates when I have rooted my phone: Mi8 Chinese version with stock global ROM.
After unroot the phone, several days after, the phone works fine with Androbench app with good performances.
I need root my phone to use Magisk hide for Google Pay in order to avoid the Google block for contactless payment.
Can anybody help me about the understanding of this behaviour?
I do not know the reason why the phone is slow after root and why the phone works fine after several days after rooting.
Thanks in advance. Regards

Hi,
Mine has hardware issue (rooted).
Didn't try to unroot it if there is a difference like you describe.
Can't help you with magisk hide. I don't use it.

I have this issue with my mi 8 guys, just happened yesterday
So flashing the latest official rom via miflash is the way to fix it?

Hello, yes in my case. Sometimes, with wipe all, internal storage included, the problem it solved.
Recently I have the issue again without root: only with custom rom flashed. Several times the issue was reproduced out of my habitual site during vacances.
Thanks
