Hey gang, trying to make sure I won't run into any nasty surprises before I attempt this, so;
I want to install the Unofficial Cyanogenmod ROM for the Mi 5, move away from Miui - but I also want to regain Android Pay functionality (and a few other apps I'd like to use that require a 'secure' device). For that, as far as I know, I need to relock the bootloader. So basically I'm looking to have my device that is:-
• Rooted
• Running custom ROM
• Custom recovery
• Locked Bootloader (or at least Android Pay functionality)
Installing the ROM and keeping the recovery updated and working isn't a problem, but I just want to make sure that I won't bugger something up when playing around with the bootloader. I've never had a device that's needed a bootloader unlock before, so I'm very tentative around the whole idea.
Is there anything that I need to know about relocking? Such as specific quirks with the device (I've read people have found themselves stuck in boot loops after locking) and if it's even possible to do so with a different ROM installed.
Thanks in advance!
Don't lock bootloader again, usually it causes issues(been there, done that).
But Android Pay doesn't require a locked bootloader, just unmodified system.
Hey guys,
So before I go ahead an attempt to unlock my bootloader and root my phone, just wanted to clear a couple of things up first.
This is my first Huawei device, previous one was a Sony, so I'm a little unfamiliar with a few things.
1. Is unlocking the bootloader required for root? If not, could someone point me in the direction of a guide to root only?
On the Sony, as long as I had a compatible firmware, I could root without unlocking the bootloader.
2. Will I lose any DRM Keys, proprietary features (Force Touch, Themes etc) through unlocking the bootloader and/or rooting? If so, can these be restored afterwards, while retaining root?
Again, with the Sony, unlocking the bootloader would result in losing DRM Keys related to visual enhancements, and were required to be backed up (via TABackup) prior to unlocking the bootloader. These could then be restored after root, and function as normal.
3. If you do lose features, and they can't be restored while keeping root. If I flash a stock ROM back on, losing root in the process, will these features also be restored?
Thanks

1) I used the SRK Tool (http://forum.xda-developers.com/p9-plus/development/tool-srk-tool-huawei-bootloader-root-t3405999) and it showed step by step on rooting. Unlocking bootloader seems to be one of the steps before rooting. Maybe you can ask somboons about it.
2) For me, unlocking the bootloader basically resets my phone. And added a warning just before the phone bootup to android (from cold state or off state) that the bootloader has been unlocked and the phone is not trusted now. Just need to restore the apps and other data through the HiSuite backups after unlocking and rooting seems to be fine. Not sure about DRM keys, and others as didn't try those out before doing bootloader unlock. But I did lost my remote set up as it was not part of the HiSuite's data backup.
3) Do a backup with HiSuite should be able to help you. Just need to identify in the HiSuite that the apps and their data is being backed up.

Thanks mate, I did have a look at that thread as well, and another (less detailed) post. Was just wanting to confirm if there was any other method without need for bootloader unlocking. Figure the less things to modify, the less chance of something going wrong, which has worked well for me so far.

Any way to remove that message while retaining root? Sounds similar to the 'yellow triangle' back when I had an S2, but that was able to be removed, is this the same?
Not too worried about backing up apps & data at the moment, I haven't fully set up my phone as I realised it would most likely be lost upon rooting. But thanks for the heads up!

Sorry I was more thinking along the lines of, if any P9+ exclusive features were to be lost during root, could they easily be restored simply by flashing a stock ROM again? Apps & app data seem to be easy enough to restore via HiSuite/Titanium etc

The orange colored message i read from somewhere that it's Android security implementation standard or something. There's red message also which renders the whole phone can not boot in unless being reset.
In terms of the exclusive apps, not that I know of. Checked with my friend who kept her device as it is, without all the unlock and rooting, and compare with my device which went through and upgrade, unlock and a rooting process - no missing apps noticed.
Thanks guys

So i've successfully rooted the phone, and yeah I get that 'your device has been unlocked and isn't safe' message on boot. It's not too much of a bother, besides being unsightly, but I don't really reboot my phone too often anyway.
I haven't noticed anything missing either, a few minor bugs have started to appear, but that might have to do with Xposed (I would guess).
Thanks for the advice & help!

Dear Abdo2,
I'm not knowledgeable about the term oem here.
But if it is an issue of dual sim usage, I presume it's built into the ROM? What I know is all P9+ are hybrid dual sim, so it should be part of the ROM that you have.
I'm using VIE-L29C636B170. And it have the dual sim support in-built...although I've not used it yet.
See if anyone knowledgeable to your question passing by here can answer you. If not, maybe you can try the question & answer thread. Or post as another new thread if really no one got your question.
Regards.

Dear djyoshii,
Good to know.
About the security message, one of it is mentioned here:
https://source.android.com/security/verifiedboot/verified-boot.html
For minor bugs, I'm not sure what you have. I've 3 games and 1 app that behaves not like when I used my previous phone (on Android 5.0). That's around 3-5% of all the apps that I used (meaning, majority works fine). Of those some of them related to Android 6.0 issue (actually the apps not updated for the Android version well). So, for me generally I would think it's marshmallow thing.
Regards.
Hi,
long time htc user (always totally unlocked) but looking to get a p9 plus for my wife (this is the important part).
can someone give me a simple answer...
if i only root the phone (for titanium backup mainly and maybe some cosmetic mods) will i be able to unroot it and return it under warranty?
phones here in Dubai are all unbranded so no problems there.
I have no need to unlock bootloader (yet )

Dear gazzacbr,
From what I tried (been a while since I last did this), one will have to unlock the bootloader first before rooting. Apparently rooting is the last step of the whole process (if you are using the SRK tools). Now, to go back to the status of unrooted, I just use the superSU's total unroot option to unroot. And to go further back to bootloader, there is an option within SRK tool but my last attempt failed to relock the bootloader back. Didn't spend so much time to play around with the unlocking the bootloader after that. So, I just use as is - unlocked bootloader with no root.
One thing you need to note, for titanium backup, I end up just using their own desktop application called HiSuite. It does backup app and app data for you. Not system apps' data though. For theme customisation, MIUI do have a friendly Themer app that you can use to change the look. The corresponding theme files (*.hwt) are zipped, so you can always use 7zip to open and edit the assets inside to the one that you want.
Ok, thanks for the good info @prismfire. As long as it could be rooted sometime later then thats fine. Will pick up one this weekend.
Am going to be jealous though as I guess it's a step up from my 'old' M8
Sent from my HTC One_M8 dual sim using XDA-Developers mobile app
Since there are some request from other fellow users, i decide to create a dedicated guide thread to show the process of UNLOCKING BOOTLOADER & ROOTING the Huawei Mate 10 (FOR MATE 10 LITE, CHECK BOTTOM OF THE POST)
Warning : Unlocking bootloader and rooting your phone come with a risk of bricked devices, bootlooping, loss of data, etc. I am not responsible for any harm that can happen during the process , ALWAYS MAKE BACKUP FIRST - use Huawei Backup App to backup your data to MicroSD, or get HiSuite ready to reflash your phone in case of brick situation happen
Pre-requisites :
1. "Enable OEM unlock" & "USB Debugging" option turned on from developer options
2. ADB & Fastboot installed on your WINDOWS 7 (YES, Win 10 has problem with Mate 10 Fastboot driver. except you know how to properly install the driver manually i would suggest you do this on Windows 7) - if you havent, search "Minimal ADB & fastboot" on XDA.
UPDATE : Windows 10 driver fix can be found HERE
3. Download FunkyHuawei Tool from : HERE - ALL CREDIT GOES TO FUNKYHUAWEI for PROVIDING THE TOOL
4. Valid Huawei Account logged in on your Mate 10
UNLOCKING BOOTLOADER
1. Go to : emui.huawei.com/en/plugin/unlock/index
2. Log in using your Huawei Account, make one if you dont have it yet
3. "Agree" to Huawei unlocking agreement presented
4. Input all neccessary values related to your device (the one you want to unlock) - IMEI, Model Number etc
5. Click "Commit"
6. You will get a pop up dialog, containing your unlock KEY. Save this key or screenshot the screen, you gonna need it to unlock your phone
7. Now, plug your phone to your PC. Assumed that you got USB debugging enabled, pop up will appear on your phone screen, asking whether you want to allow the PC to access your phone or not. Authorize the request
8. Fire up ADB on your CMD/Terminal. and type
Code:
adb devices
9. Your devices should listed on your adb window, if it isn't, either you didnt install the adb driver properly, or your usb port has problem
10. Now type
Code:
adb reboot bootloader
to reboot your phone to fastboot mode
11. Once the phone is booted up to the fastboot mode screen, type this in your CMD windows :
Code:
fastboot oem unlock [your UNLOCK KEY here]
- without the brackets
12. Confirmation dialog should appear on your phone screen, give you a warning about unlocking bootloader, just go with proceeding the process (YOU WILL LOSS YOUR USER DATA]
13. Once the unlocking process is finished, your phone will boot up to initial set up stage
14. Set up everything up until you can re-enable USB Debugging option in Developer Options (you can skip all account stuff, security and elses, you gonna do it again anyay after ROOTING)
15. Plug back your phone, and from your CMD Windows, retype this code :
Code:
adb reboot bootloader
16. Your phone will rebooted to FASTBOOT MODE again - now close your CMD Windows
ROOTING
1. Now launch "FHMate10Tool.exe" which you have downloaded from the prerequisites step

CONGRATULATION, YOU HAVE ROOTED YOUR MATE 10
Addendum :
FOR MATE 10 LITE ONLY
Use same step to unlock bootloader.
Download TWRP from HERE and SuperSU from attached.
Place SuperSU to MicroSD and place TWRP img file to your directory in PC where fastboot and adb installed
Reboot to fastboot mode,
Execute this command :
Code:
fastboot boot twrp-mate10-lite.img
Your device will boot into temporary TWRP,
Go to Terminal in TWRP and type this :
Code:
echo "systemless = true" /data/.supersu
(Tick the bottom right corner)
go back to TWRP main menu and choose "Install"
Choose external storage and choose the Supersu.zip file and flash it,
Reboot System
Your device should be rooted.
Note : this method wont install TWRP to your device. You can install it using fastboot flash recovery twrp-mate10-lite.img command, but since the TWRP is still in beta stage, i do not recommend it.

Thanks for the info, I'm having difficulty getting a Windows 7 machine going, anyone know how to install the fastboot drivers manually on Windows 10?
Hello. I request that you don’t link directly to the google drive download page of the FunkyHuawei tool but rather if you want to link, link to the Reddit page that explains how to use it.

Basically the idea is, I might update it if a bug is found/fixed, so it should point to the latest version to avoid issues. If we have a direct link, that makes it difficult. Thanks

@otonieru , i have mate 10 standard,
- If i rooted the phone would i still receive OTA ? and if i received and installed them, would that brick my phone or just remove the root?
and if my phone ended up being bricked, is it easy to just flash back the rom of huawei using Hisuite ?
- is it easy to unroot the phone back to original, if i needed to use back the warranty? or maybe just flash the huawei rom.
- can the root be hidden ? like magisk ?
Thank you very much for this thread, it is a must ! <3
Two questions (sorry, I'm new to Huawei world...):
1. UNLOCKING BOOTLOADER does not void my warranty, right?
2. Will I loose root when install OTA update?

2. Yes, you lose root.

If you root you will apparently still receive OTA. Receiving an OTA will unroot your phone, but should not brick it.
You can't unroot the phone back to original. Even if you relock the bootloader, it will show relocked, not locked. There are tools which you'd need to pay for which can help in that case.
The root cannot be hidden.
Anyone who roots, I urge you, be VERY VERY careful. Huawei phones are very finnicky, brick easily (the Mate 10 even more easily than previous versions), and there is no free way to restore them if they do brick. Even with paid methods,
it's not easy.

The procedure is safe, but it's what you do with the root powers that could cause a brick. If you touch the wrong file on the phone, caput. In the worst case, the phone won't turn on, won't be recognized with USB, and can't be unbricked.
Obviously you're protected from doing that when you don't have root.
I've already lost two test devices to the symptoms described above.
So my opinion is, as the developer of the tool, root only if it's absolutely essential to you. And if you do root, only use the root privilege for things you absolutely must do, or things that have been tested on the phone and proven to be safe. Hopefully you won't brick it, but I need to put out this warning so I'm not blamed if someone does.
Any other down sides to unlocking bootloader and or rooting on this device eg apps auto removed, loss of camera functionality or codecs disabled etc as seen with other devices?

None as i may concern. Android pay wont work though, and some banking app as well. Since those app wont allow rooted phone.
But if you didnt use such an app. Or like me, have another phone for that, then its perfectly fine.
For me, there's more benefit / advantage come from rooting
Example :
1. Effective adblocking (not VPN solution)
2. Removing unneccessary stuff and app
3. Youtube without ads + background play
4. Better battery life (with appops, greenify, and my own GMSDoze)
5. Enabling VoLTE option
6. Audio MOD (gain, and better dual speaker)
7. etc

Good point about NFC pay methods, I do use those a lot.
I read a few people here having issues with their devices eg here, Lg devices has a similar issue with camera and missing appps, Samsung devices would lose the IR blaster after bootloader unlock.

Working just fine on mine. But experience might be vary.
I want to run the latest GCAM with wide angle AND night mode but it says I need to unlock the bootloader to to do so.
According to moto's website:
"You will lose all media and content on your device and will need to reinstall all applications downloaded from Google Play."
Is this true? I *MIGHT* be willing to do it but I doubt my wife (who also has a X4) would.
Other questions:
1. Can I get OTAs after I unlock?
2. Any other side effects I should be aware of?
Yes, unlock will wipe. Unlock causing ota updates..... depends on why you are unlocking, you are doing it to write to system. So depends on what you choose to write.
- Unlocking bootloader wipes as you confirmed already on Motorola website already.
- Can receive updates but not install. Have to wait for full image to be available and can manually flash yourself without wiping userdata.
- Not aware of any side effects or not sure what you mean. Phone continues to operate.
Hello, I'm looking to get a new Android phone and I really like how the Sony Xperia 1 ii sounds, but, I really don't want the pre installed apps and I would rather fully delete them then just "disable for the current user".
If I rooted a Sony Xperia 1 ii then deleted the apps I didn't want, and I unrooted the phone, would it be as secure is it was before root? Also, would the apps I just deleted come back with future OTA updates?
Since I don't want to maintain a rooted phone and have to keep up security myself while it is rooted.
If you update it after that there's no telling what could happen is my guess.
Maybe do some ADB edits and call it good.
Or use Package Disabler for non Samsung phones and bypass all the monkey business entirely. Phone remains stock.
adb tools can fully delete pre installed app.
rooted phone cannot use some bank app.
If you want to rooted the phone,
you must unlock bootloader before root,
this step will clear all user data in your phone.
And when you want to get OTA and unroot,
you need relock bootloader.
And you need to flash firmware once before relock bootloader.
If not, you cannot boot into system.
So, your preinstall app will be back after relock bootloader.

Thank you for your reply.
I read on another forum that removing apps with ADB only "removes" for the current user. Not fully deleting off of the phone.
Is this not correct?

No, it's fully uninstalled.
But the install file (apk) is continue in your phone. So, if you add a new account(or use adb) , they can come back.
After use this method to uninstall app, just storage will be use (apk file) . The pre-install app will never use any ram and battery.
(I use adb method to delete "file" app before, but I cannot re-install it by adb.
Finally I need to make a clean flash by newflasher to bring it back. )
