1 - There are no side effects that come from rooting the phone, the side effects can arise when you flash a dirty rom, but thats the joys of rooting I guess. Trying different roms/kernels until you find the combination you love.
2- After rooting, you cannot go completely back. Instead of your bootloader saying Locked, it will say RE-Locked, so they will know something is up. But apparantly if the issue is hardware caused, such as the WiFi issue, then I think they still repair under warranty.
3 - To be honest I can't answer that one, im sorry !
4 - No they are not the same, a Kernel is what communicates with the hardware, and passes that information back to the software and vice versa. Without the kernel, the hardware/software would have no way of communicating.

5 - Fastboot is how you modify your bootloader, which is how you flash the boot.img in order to not make the phone bootloop when installing a custom rom.
Hope thats helpful !

Hi the only bad side effects are if you do something wrong
You can return back to stock usein ruu's but not back to locked
Ye a boot.IMG is a kernel and I no of some noob friendly tools to help you unlock and fastboot kernels without having to do it manual wich helps
If you won't help through all the steps I'm welcome to help

So, actually, the boot.img is a binary file, that contains the kernel and the ramdisk.

mmmmmmm I'm now confused !!
According to:-
1- I know the rooting will make the warranty gone and also I won't be able to update OTA !! so how to avoid these problems
2- There are difference between Locked & Relocked ?? And if I relocked my phone the warranty will come back & I'll be able to update OTA ??
3- No one had answered me !!
4- I have three different answeres !!
5- I still don't know the meaning of Fastboot
And thanks to every one who had answered .. +1 thanks to every one
And I hope thant you answer me ...

1/2) You can unlock to install OTA. Even if you lose warranty, you are usually protected by consumer law in your country.
3) Spelling
4) I'm right, if you keep asking, you'll have 4 answers
5) Fastboot is a setting that allows you to more quickly boot your phone. It also breaks some apps.
5) Fastboot is a tool for flashing bootloader and recovery on your phone, as well as other diagnostic tasks.

1- Means that the warranty won't come back ??
2- What are the difference between Locked & Relocked ?? or it's just spelling difference ??
3- Okay
4- hahahaha .. Okay
5- I know fastboot the setting but fastboot the tool I want to know it more & more .. why we need to flash bootloader & recovery even that we have it .. and how we flash the bootloader even that the fastboot mode we get it from the bootloader (Hboot) !!
+1 for your help

there is no difference between locked and relocked. Relocked means you had unlocked the bootloader and Now htc knows about it.
You can not flash custom roms from stock recovery, Since there is no option to flash the zip files. For that you need to install CWM

Is there any problems when HTC knows that this phone has relocked the bootloader again ?? could I unlock & relock my phone may times without problems ??
What about the warranty ?? I'll lose it even after relocking my phone ??

Yes there is a problem.. by unlocking the bootloader you may void your warranty. By this means Htc have the authority to reject your warranty claims. But at some places they accept the relocked bootloader under the warranty. It all depends on place, service center.. and the answer of your 2nd ques would be yes.. you could do it as many times you want. And you could also get the official OTA updates. So decision is yours.. check your phone for any defect. Then think about unlocking the bootloader.

I have a small question .. how could I know that my phone comes with warranty ?? as I bought the phone from eBay without warranty but in the box there is a Warranty Statement !!

warranty statement does not matter.. If you have the bill you may contact HTC if your phone comes under warranty or not?
but since you bought it without warranty.. So I doubt there would be any chance that it may come under any sort of warranty.

Okay Okay >> THANKS

Hboot is your bootloader. Like you get different types of bios menu for different pcs
Hboot is your bootloader not anything else. there are different hboots out there but they are all bootloaders (you could call it bios).
This means they tell your phone what to do when you press the power on button when it's off or you hold the volume down key and power on

The phone was released end of march or april I believe. In that case you have warranty till March april 2014 by default as all phones come with 2 year warranty and your phone cannot possible be older than march as it was not available before then. So every single one x without a receipt had warranty till 2 years from release date
Even HTC know that so don't worry.

I don't believe that to be true, for the first two years of a phone released, you can do without the bill receipt. If you were say to buy a HTC Desire HD a year ago brand new, as its 3 years old the build now; the receipt would be needed to prove you bought it within the last 2 years and not on release. But for a phone that has just been released you do not need to prove this, even HTC know you couldnt have had it more than 6 months

Are there any disadvantages of unlocking the bootloader to root?
As custom ROMs/bootloaders will not be able to receive OTA updates from HTC, is there anything that an update from HTC can do which custom ROMs cannot. (e.g. low level power management and performance enhancement stuff)?

OMG!!!!
HBoot = the partition table on your phone. It's essentialy the way that the internal space is partitioned.
If you have let's say 5Gb of internal memory then yoy can partition it let's say like this:
1. System - 1Gb - where your ROM is installed
2. Cache - 2Gb - the cache for the sys apps and apps installed on internal
3. Data - The rest - where the apps are installed.
But to be perfectly honnest I really don't know why there would be any talk about HBoot as long we don't even have S-Off even, whem that is manditory.
As for the bootloader... That is the procces of booting the operating system in android, or any other OS. This tells the phone what to boot and what to start and in what order....
Hope it helps some of you.
Talking about HBoot I really don't think we'll be needing a different one any time soon as the sys partition is more then enought for the existing ROMs out there... for now at least. This was used mostly when you would've had a internal memory like 512 Mb and you'd use a sd-card's EXT2/EXT3 partition as internal memory for cache or data...
Hope it's more helpfull than confussing.

When you unlocked it you voided your warranty. You knew that, and if you didn't you need to read things. This won't be possible until we have an S-OFF method, which may never come.

@anwarmanaf
Actually, if you first remove root, then flash the stock recovery, then relock the bootloader you will be back in warranty.
It is because HTC does cover unlocking bootloaders in their warranty IF it is the STOCK bootloader they unlocked.
On some device people have been able to make CUSTOM bootloaders and gain S-OFF without HTCs permission so this method is considered voiding warranty.
Of course if you have S-OFF you can always just put it to locked status but that is not available for our devices as of yet.
Basically your good as long as your on stock everything and the bootloader is relocked. And yes, you need the stock recovery. The reason you keep getting sent into the recovery/bootloader is because you might just be using CWM 6.0.4.7 or another variant such as TWRP or Philz.
If you have a problem with hardware, that is a manufacturer defect not something that happened software wise because of the bootloader or flashing custom ROMs.
For example, if the power button got stuck, charging port stopped working for unknown reasons, dead pixel/ white line on the LCD screen, speakers stopped working, headphone jack not working, camera malfunctioning, or if your able to brick it completely so it can't be turned back on and you take it into the store for a replacement on the spot and bring the stock charger so they can see its the device not the charger.

So I have been having severe battery issues that I suspect could be a faulty battery, and would following this procedure make my warranty good again? I unlocked the bootloader 2 hours after I got it[emoji28] probably should have tested the battery...

Have you tried Battery Calibration by NeMa to fix the drain issue? Also, if you have things like Facebook and messenger they constantly ask the device every few seconds to refresh data for those apps along with a few others. As long as that is happening battery drainage will be high.
Greenify fixes the constant asking for data issue.
I run my device on Power Saver with the "Disable HW Overlays" checked and have everything checked for the Power Saver options.
Device runs like heated butter

Replaced camera module - different drivers(?)

Hi there!
My 420N's camera has been broken since I've got the phone so I've sent it back and asked to replace the module. They did it, but the phone got wiped in some way (the apps stayed, but all the settings, cache etc. were gone) and it made me wonder - is there any way I could have some different kind of camera drivers now? I'm asking because I want to flash RR/LOS (haven't decided yet) SO BADLY and I don't want to find out the camera isn't working anymore, even after reverting to stock. Also - if that happens, I can't send it back again because of unlocked bootloader.
Thanks in advance

Then bootloader state shows 'relocked'. Unless guy who sold you the phone is dumb in that case I want to know about that shop. 
 @op if your camera works with stock firmware it will work with custom one as well.

Bootloader unlock for K10 qualcomm is different than normal bootloader unlock for other phones. Check my bootloader unlock thread to understand how it works. K10 qualcomm doesn't have true bootloader unlock, it is just secure boot is off. So it doesn't show bootloader is "locked, relocked, unlocked" status.
Flashing the stock firmware, will also flash the stock "aboot" which replaces the patched bootloader.
Please read the threads properly before commenting.

Flashed RR and camera works just fine. Thanks guys, question answered. @edit: Tried to close thread, just realised I can't. Too bad, now this reply looks just outta place.

Call Recording and Indonesia ROM

Just got a Redmi Note 8 Pro with Global ROM and discovered that call recording won't work due to Google/Android Pie limitations.
After some searching, I found (on this forum) that the Indonesia ROM supports call recording on this phone.
Here are my questions:
1. Will burning a different ROM affect my warranty?
2. Will I lose any functionality by switching from Global to Indonesia ROM, and if so, what? Specifically, will NFC functionality be affected?
3. If I ever do a factory reset, will the phone revert to Global ROM?
4. I found the Indonesia ROM files here. There are three files called Recovery, OTA, and Fastboot. Do I need them all? If so, do they need to be burned in any specific order?
5. Where can I find complete instructions for burning the Indonesia ROM? I am new to Xiaomi, and the last time I burned a ROM to a phone was 5 years ago (Samsung); I don't remember anything, so I'd like instructions that assume nothing and don't skip any steps (instructions for intelligent dummies). I found these instructions for installing TWRP, but there's nothing about what to do next, and there's a list of pre-requisites with no explanations (Unlocked Bootloader, Phone Drivers, ADB and Fastboot Drivers), making the instructions insufficient for a noob like me.
Thanks much.

Hey,
Before going any further you first need to make sure what region is your phone. Is it a Chinese phone (bought from AliExpress for example) or a real Global phone (bought from a local store/official retail). Because you could very well own a Chinese phone shipped with a Global Rom flashed on it and this could result in some problems for you in terms of what you can do with it and how you can do it.
If you bought/received a phone with already unlocked bootloader, you should return it.
Unlocking bootloader should only be done by you when you need it.
1. Technically unlocking bootloader, ESSENTIAL step prior flashing anything, void your warranty.
However and that's what is interesting, if at some point you decide to flash back your original region rom (here Global) and lock back bootloader, none will know but Xiaomi servers you once unlocked this device certainly not a local reseller. So in term of warranty you should be safe, that is of course unless you brick your phone doing stuff you were not supposed to do with a locked bootloader if you are following.
2. If not mistaking, I think you loose NFC. Indian phones for sure do not have NFC at all, for their version, the chip was replaced with a 2nd SIM card tray (not shared). Not sure if you read the functionality afterward using rooted tricks.
3. No that does not work this way. When you are running a Rom, any version, if you factory reset that room, you just return to installation screen of that given Rom.
To return to Global Rom, you will need to reflash that Global Rom using the same method you did successfully flashing the Indonesian Rom (or any other rom) for example.
Would be wise to first download the exact version of the Rom you are currently using on your phone for archives purpose (BURN IT on good quality medias!) to revert back to it when/if needed. You can also archives OTA updates of that version you may not have taken yet to apply them manually if you ever revert back to that Global Rom and want to.
4. Different versions depends on what you are doing. In your case Fastboot version is what you need at the moment. You can find all different kind of versions of Roms for your RN8PRO on that site
As for the way to flash them, order and everything, you will need to look for guides online,
I dont think any order matters, just make sure to flash them all before rebooting disconnecting device. But if you are unsure of what you are doing, you'd be probably best using a tool such as MiFlash.
5. Here you can find one from the MIUI community website guiding you through the use of MiFlash to flash a stock Rom on your device.
Just note you do not have to use any tools to flash the .images of all partitions, you can easily doing it from command line using fastboot flash command one after an other.
Also note that installing TWRP is usually not needed to flash stock Roms (unlike flashing custom roms). Trying to mess up with the recovery partition is actually what seem to brick most of the devices.
However please note UNLOCKING your BOOTLOADER is MENDATORY.
Hope this helps.
Regards,

doesnt matter if you switch to any rom variant .i have switched mine to indonesian ,europe and indian and alll worked fine execpt indian version felt a bit laggy .just download the fastboot version of the rom and flash it through mi flash tool xiaomiflash .your bootloader needs to be unlocked and dont forget to check cleann all button in mi flash and dont check clean and lock

I have got global version and changed imei with unlocked bootloader. Can i flash indonesian rom without lose f my imei?
Thanks in advance for your answers

Muad.Dib,
Thanks for your detailed reply.
If I understand correctly, unlocking the bootloader voids the warranty just the same as rooting the phone, so if all I want is to get call recording, I may as well just root the phone and save the bother of flashing a different ROM.
Does that make sense to you, or do you see any advantage to flashing a different stock ROM instead of just rooting the phone? From past experience I've seen that rooting has additional benefits anyway.
BTW, I bought my phone on Banggood. It was advertised as Global ROM, and that appears to be what it has. As soon as I turned the phone on it updated to MIUI Global 11.0.2.1; I don't know what version it was before the update.

Just note you do not have to use any tools to flash the .images of all partitions, you can easily doing it from command line using fastboot flash command one after an other.
Also note that installing TWRP is usually not needed to flash stock Roms (unlike flashing custom roms). Trying to mess up with the recovery partition is actually what seem to brick most of the devices.
However please note UNLOCKING your BOOTLOADER is MENDATORY.
Hope this helps.

Muad.Dib,
Thanks for your detailed reply.
If I understand correctly, unlocking the bootloader voids the warranty just the same as rooting the phone, so if all I want is to get call recording, I may as well just root the phone and save the bother of flashing a different ROM.
Does that make sense to you, or do you see any advantage to flashing a different stock ROM instead of just rooting the phone? From past experience I've seen that rooting has additional benefits anyway.
BTW, I bought my phone on Banggood. It was advertised as Global ROM, and that appears to be what it has. As soon as I turned the phone on it updated to MIUI Global 11.0.2.1; I don't know what version it was before the update.

You're welcome, I am happy if I was useful to you in any kind of ways.
Well yes and no. Yes apparently you 'could' achieve call recording when rooted (yet I still fail doing so even if I installed the default MUI apps module I got from Telegram group. The setting to automatic recording is set to on yes, but I dont see recordings in the supposed destination folder nor I can see a simple button to record any voicecall I used to have on older versions of Android. Me failing to make it work - I did not try very hard to be honest - does not mean you cannot find someone who succeeded into doing so in that telegram group for RN8PRO).
That said it would not be a 'native' solution, just a patch/workaround. If it works well great, if not, well...
On an other hand by flashing to a Rom which does support it natively, well you are covered for the use you need.
So the advantage I see (with the included disadvantages) is better support for the function which is not supported for privacy reasons en Glob/EU market.
Does that come at a price?
Probably.
For example are you ready to trade off NFC for native call recording support? That may be a choice you have to make in the end. Again that said, if you root your phone on that new Rom, install NFC drivers manually as root (I see no reasons why that would not be possible after all) you may be able to patch NFC on that other Rom since unlike Indonesians market phone, you do have NFC hardware.
For example, myself, I wish I could have made that kind of bargain/trade off, giving up that NFC feature I have no need for, to get 8GB or Ram + 2x Sims + SD and not an hybrid tray. Unfortunately that's not the kind of trade I could make here in EU unless I would have ordered directly from Amazon.in (assuming that would have been possible) or third party website, but that was not possible for warranty reasons among other things.
Hope this helps.
Regards,

Yes it does as it is officially available in every variant expect indian variant.

UPDATE:
I finally had the time to test the MIUI-default-apps Magisk module available for download on Telegram group, originally made for MIUI 11.0.1.0, and it works properly on MIUI 11.0.2.0 EEA. Does not require changing Rom.
Hope this helps.

Well, I have finally started the process, but got stymied by the Bootloader Unlock tool (Couldn't unlock. Please unlock 168 hours later.). Quite frustrating. I see that a lot of people have this problem and had to try again more than once, waiting a week between attempts.
Is there a workaround or do I just have to wait a week and hope for the best?
Also, assuming all goes well and I eventually manage to unlock the bootloader and flash the Indonesia ROM, do I use the same tool to re-lock the bootloader (in order to restore the security of the phone)?
And if I want to unlock again in the future, will I again possibly get the "wait and try again next week" message, or does that only happen the first time?
Thanks.

No workaround, you just have to wait (and yes I know how freaking frustrating it was for me...). You can even start meditation classes meanwhile it helps

It depends on what your the flavor of the phone you got. You may want to have a look at that other thread Relock bootloader after flashing ROM Indonesia where we actually covered this exact subject
The good thing about that 7 days wait period is you can gather all the intel you need to be 100% ready when the time come to seriously mess up with things.
So you know, once your bootloader is unlocked, first thing you will want to do BEFORE anything else, is blow off that security which needed Auth Account to unbrick account (ONLY WORKS FOR PIE, ANDROID 9 MIUI VERSION BEWARE).
All information is here: [GUIDE][INFO][PSA] Redmi Note 8 Pro - Megathread

The waiting time is for one time only (THANKS GOD!).
So if you relock, beside having to get your hands on the unlock tool once again and have added the same infos as for the first time in the phone, you will be able to unlock right away.
That's at least a good news
Hope this helps,

Yes of course.
It is a module you can find on the Telegram group called "Redmi Note 8 Pro | OFFICIAL".
Like me you will have to go in there even if you do not use Telegram.
Once there and you got the /notes it is called the default apps.
I cannot share it myself here because I am not the developer of that module, as you can understand that's against forums policies.
All I can tell you is it works correctly on EEA MIUI 11.0.2.0.
Good luck!
Hope this helps.

Thanks man, I got it! ?

I have disovered that there are different NGC protocols and that my Redmi Note 8 Pro does not read NFC cards of some protocols. I'm wondering if it might not be a driver issue. where would I look for NFC drivers?
Thanks

Sadly I have no idea. I think you should make a new thread about this to get more visibility and probably more answers from people who actually knows the answer.
Hope this help.

Hey,
Sorry was AFK for a while. In case you still need answer, going to reply just in case.
Well there is not much to add, you simply install the module from within Magisk once it installed, you reboot, and it works out of the box, you go in the settings and you set it as you like.
Good luck!

Do i need to root before installing it ?
