(CLOSED)Root Your Huawei Honor 4C

Go to new thread wid Working new Root Method and CWM Recovery...
Here is new thread Honor 4C Root+CWM Recovery by @inshaalmirza
THIS THREAD IS CLOSED.....
Today i found a Rooting method of Honor 4C nd other Honor Series phones to Root them easily,,,
First of all, You should Unlock Bootloader so that on every reboot, Your Root shouldn't damage. You can unlock bootloader by simple procedure...
Just mail at [email protected] wid subject that unlock bootloader huawei honor 4c and in mail type all info..like imei, serial no. Product number nd model number...they will send you unlocking code....
you can unlock bootloader wid that code then and root permanently....
After receiving the unlock code, write down the code;
download the installer utility ADB and Fastboot and set (if you have them yet);
direct the cursor on the folder ADB, hold Shift and the right mouse button and choose "Open Command Window";
connect your phone to the PC in the "media device";
at the command prompt prescribe ADB Devices ;
then we write ADB reboot bootloader (the device will reboot mode fastboot);
then typed fastboot oem unlock **************** (where the asterisks replace unlock code);
write fastboot reboot and wait for the device to boot the system.
Now download below attached app named Kingroot...
Now install it in your huawei Honor 4C,,,
After this,, open kingroot nd press TRY ROOT, wait for sometime nd it will successfully root your Honor 4C,,, enjoy root apps easily now,,,
If It didnot succeed, then try any other version of KingRoot not kingoroot... It will do the JOB...
DISCLAIMER,,,
ROOTING may void your phone's warranty,,,use it at your own Risk...
If you found it working,,, just press Thanks button below,,,

I have read on another forum that without unlocking the Bootloader the phones becomes unrooted after a reboot?
Is there a way to do a nandroid backup with the default recovery?

Right

Product number nd model number...they will send you unlocking code....u can unlock bootloader then and root permanently....

I already have the unlock code from huawei. But how exactly can you do a nandroid backup with the default recovery?

Default recovery lacks the option of backup and restore...wait for any dev to port recovery for our device...or i will port after 1month,,,
@inshaalmirza

guys i have the unlock code now. How do I use it to unlock the bootloader?

How to unlock bootloader.... Guide
After receiving the unlock code, write down the code;
download the installer utility ADB and Fastboot and set (if you have them yet);
direct the cursor on the folder ADB, hold Shift and the right mouse button and choose "Open Command Window";
connect your phone to the PC in the "media device";
at the command prompt prescribe ADB Devices ;
then we write ADB reboot bootloader (the device will reboot mode fastboot);
then typed fastboot oem unlock **************** (where the asterisks replace unlock code);
write fastboot reboot and wait for the device to boot the system. Ok

Do we lose the ability to get OTA updates after we unlock the bootloader? This is the only reason I haven't unlocked my bootloader yet.

Untill yet,,,,i think rooting may not got ota updates,,,,we should unroot or install stock rom for ota,,,,
@inshaalmirza

You can google it about bootloader link wid OTA nd post here,,,,

Did you flash the new updated ROM from here:

UNLOCK YOUR BOOTLOADER​
WARNING: UNLOCKING YOUR BOOTLOADER VOIDS YOUR WARRANTY.PROCEED AT YOUR OWN RISK.
NOTE: Unlocking the bootloader will Wipe/ factory reset your device, and will delete all personal data from your device such as apps, photos, messages, and settings.
INSTRUCTIONS:
Make sure to take a backup of your entire device data.
Download the Android SDK OR Download the Minimal ADB and Fastboot
Install the latest Motorola USB Drivers on your desktop. Download here.
Put your device in fastboot mode (power off, then press the power and volume down buttons simultaneously).
Open Command Prompt on androidsdk/platform-tools/ (Hold Shift and right click and press open command window here)
Connect your Phone to PC
Type this in the CMD prompt window - fastboot oem get_unlock_data
You will get a return string. Copy it. [Right Click-Mark- Mark the text by pressing the shift key-Now press Ctrl+C]
Paste all the lines together in a notepad. Remove the empty spaces.
Now go to the Motorola Site.Sign in using your Google account or Motorola ID. Scroll down the page and paste the copied string in the field at step #6. Then click on ‘Can my device be unlocked?’, after which a "REQUEST UNLOCK KEY" button will appear at the bottom of page.
To get your unlock key, select the ‘I Agree’ option. Note: You will receive an email with your Unlock Key at the email address you used to log in there.
Important – Copy the 20-character key that Motorola sent you via email. Make sure your device is connected.
Then in CMD type: fastboot devices (To check your device is connected)
Then type: fastboot oem unlock UNIQUE_KEY
NOTE: In above command, replace the word ‘UNIQUE_KEY’ with the unlock code that you got via email. Then hit enter and the unlocking process should begin. Wait for a while and soon you’ll see ‘Bootloader Unlocked’ warning on your Moto E.
To relock the bootloader:
Go to Fastboot and give the command fastboot oem lock
You can always appreciate my work by pressing the Thanks Button.:good:
Good Day

After you unlock your bootloader you can flash SuperSU in a custom recovery but someone would need to make one of those

Root Moto E4 (XT1768)
Here's what worked for me (I have the snapdragon version of this phone):
Follow the following at your own risk!
If you're an expert with rooting, the twrp build that works for this phone is at https://forum.xda-developers.com/g5/development/unofficial-twrp-3-1-0-0-moto-g5-t3574450. Otherwise, details are below.
I'm assuming whoever is reading this has some rooting familiarity.
The short version is:
1. Unlock the boot loader
2. Boot twrp
3. Flash su and no-verify zip
4. Reboot to root'd phone.
0. Prepare
Get the following:
i. Motorola usb drivers: your pc won't talk properly with the device without these. google around for these.
ii. adb and fastboot: used to unlock the bootloader and boot twrp https://developer.android.com/studio/releases/platform-tools.html
iii. su zip: I used phh's https://superuser.phh.me/superuser-r259.zip you can probably get chainfire's or whatever else working
iv. no-verity-opt-encrypt-5.1 zip: https://www.androidfilehost.com/?fid=24459283995297893
v. twrp: this build seems to work for the E4 https://forum.xda-developers.com/g5/development/unofficial-twrp-3-1-0-0-moto-g5-t3574450
vi: (optional) stock roms: in case you need to go back https://androidfilehost.com/?w=files&flid=195327 applying these with RSD lite (if RSD can *actually* detect your phone) or manually (https://www.youtube.com/watch?v=njXQYn53SPc) should work.
0.1 Prepare the phone:
Get developer options on android and turn on "OEM unlocking" and "USB debugging".
Test that your pc can see the phone by running:
Code:
adb devices
0.2 Dump your zips onto the phone:
For this, I dumped the superuser-r259.zip and no-verity-opt-encrypt-5.1 zip onto an sd card (formatted as external).
I didn't try this without an sd card.
0.3 (optional) install the superuser apk
Install the apk before flashing to get root immediately after booting back from twrp.
1. Unlock the boot loader
The post here details how to unlock the motorola boot loader. Keep in mind it will probably void any warranty on the phone. This process involves signing up for a motorola account to get the unlock code.
https://forum.xda-developers.com/showpost.php?p=72878183&postcount=2
2. Boot twrp
Read the warnings in https://forum.xda-developers.com/g5/development/unofficial-twrp-3-1-0-0-moto-g5-t3574450
Because we'll be flashing stuff here, the phone may refuse to boot afterwards since a part of it changed without its knowledge. That's why the no-verify zip is necessary, to bypass this check on boot.
Put your phone in fastboot and run:
Code:
fastboot boot twrp-3.1.0-0-cedric.img
3. Flash su and no-verify zip
In twrp, hit cancel on the decryption screen and start twrp in read.
Go to install, switch to sd card, find the the zip location and flash su then no-verify.
4. Reboot
That should be it. When you reboot back to android, install the superuser apk if you haven't already and feel free to use your root.

Moto e4 is not on the list of the phones that can be unlocked, I have already chatted with moto customer care and they told me its bootloader can't b unlocked yet.

Now my phone isn't booting, says it can't load the kernel, I flashed the no verify thing but that isn't helping
---------- Post added at 11:49 PM ---------- Previous post was at 11:44 PM ----------
And now after turning it on and off many times it's working!

I still can't figure out how to root it, any ideas? I flashed SuperSU in TWRP many times and it's still not working.

First, I unlocked the bootloader through motorola's tool. Second, as there is no official TWRP for the e4, I used the Moto G5's TWRP img to BOOT from. (Flashing will not work, boot from it using fastboot) https://forum.xda-developers.com/g5/development/unofficial-twrp-3-1-0-0-moto-g5-t3574450
After in TWRP, I made a backup of stock everything. You'll need it if something goes wrong during the entire process.
After making sure that I was backed up, I then flashed Magisk 13.1. After that successfully flashed, I then flashed this file: https://www.androidfilehost.com/?fid=24459283995297893 . After rebooting (This may take a while), everything looked much the same, and it may look the same for you as well.
In my own case, the Magisk ZIP that I flashed did not install the Magisk Manager. Install that via the APK available in the Magisk 13.1 thread. After I did all that, I had successful root.

Hmm, I tried again and it gave an error that it couldn't mount the magisk image, here's some logs

Magisk won't install if your boot image is anything other than stock. So if you've attempted other methods, you'll need to restore the boot to stock.

Stuck on error mode and I don't have access to recovery mode phone p9 lite

Well I had unlock bootloader from my phone and update it to nougat then try to flash TWRP again but i made a mistake and I tried to flash TWRP for marshmallow so I didn't have access on recovery but I didn't know it because I didn't try to go to recovery mode aafter that I try to relock the bootloader because I thought it will be okay to do that... .(stupid me)
So now to open my phone I have to let the battery end elsewhere when I try to restart the dive or try to power it down and open to recovery mode it gives me the error screen with that Android logo (sorry for my English )
Thanks everyone who will help

I can't alunlock the bootloader because the program I am using to unlock it it turns off the phone and restart it and wait for the device to connect but the devise restart on error mode

i have similar problem.
P9 lite is in error mode. i have download update.app put it into dload folder.
But after forcing update volume + - and power only red lightning shows up, i guess battery is low.
But after connecting to charger error mode appears again and i am not sure if it is charging or not.
Any idea?

If you have the same problem with me with the error screen let the phone to close and then plug in the charger and press the power button to open your phone .. then charge it shut it down normally and do the thing with volume +- I guess it will work.. (I don't know)

What you want to say is probably that you get an error when forceupdating. What I've heard there's no error mode in the 'Huawei-world'.
You're probably getting an error because the updatepackage is corrupt or not working/is not compatible with your device.
How to enter fastboot:
1. Power off your device.
2. Plug in your device with a USB cable to to your computer. (Make sure that the cable supports file transfer.)
3. Press and hold Volume up/Volume + and Power button.
4. You're probably in fastboot now.

i cannot turn off phone, it still rebooting into "error mode", even if i press powert button and both volume keys it goes to red lightinng screen and again reboot to "error mode".

Power off your device. Hold down VOLUME DOWN + POWER button, remember to have your USB cable connected to your PC. Boom, now you're in fastboot. Then you just put in the command.
To see serialnumber:
In fastboot type fastboot devices one of the number will be your serialnumber, probably the longest number.
Unlockpassword:
https://hwid5.vmall.com/CAS/portal/...ndex&loginChannel=22000000&reqClientType=2023
Sign in there with your Huawei ID (it has to be more than 2 weeks old for some reason) follow the onscreen instructions and after a while you'll get your unlock password.

Mi A1 Bootloop after ota update and Locked Bootloader

Hi,
I've installed an ota update and the device didn't boot... it is stuck in a bootloop....
When i try to flash via fastboot, it appears an error saying that the device is locked ant cennot erase...
via fastboot oem unlock i get the error message: Remote: oem unlock is not allowed
via MiUnlocker the unlock gets to de 50% and gives an error and on its logs it says: Remote: oem unlock is not allowed
I tryed to flash TWRP with command fastboot flash recovery but the error is the same: remote: partition flashing is not allowed
Can anyone help me please??
I'm stuck on the bootloop i can't go to setting - developer - allow oem unlock option!!

Have you tried doing a Factory Reset from stock recovery?

This is a strange behavior, even if an OTA update corrupted the system for some reason, the phone should boot from the original slot.
Have you tried switching slots manually from fastboot ?

How can i do that?

Hello!
I've faced the exact same problem yesterday.
You need to force the phone to boot in EDL mode by opening the back cover and short circuit 2 pins as shown in THIS video.
After you have the phone in EDL and being detected by your PC (you need the correct drivers, you may get them on THIS thread by @CosmicDan), you may use MiFlash Tool to flash official PIE Rom, access developer options and enable oem unlock to be able to unlock your phone again.
If you wish to revert to Oreo, please use THIS guide.
Cheers!

@auris1993 I'm still writing the guide out, adding more detail to it but it's mainly completed enough to try & unbrick your 8T thanks for the like btw.

Thank you for a detailed guide.
Though i've never heard of Global OnePlus 8T KB2005 with Unlockable Bootloader.
There may be some issues with getting token from OnePlus and unlocking bootloader on T-Mobile variants, but on other models is usually painless.

When you gotta bricked 8T that cannot boot into Android only fastboot mode & recovery & fastbootd mode with a locked bootloader that's impossible if your OEM unlock wasn't tick on with USB Debugging on before the brick right.

If your on global Firmware you don't need a unlock token to unlock the bootloader correct. Yes T-Mobile would need an unlock token of course.

Also when u get bricked in this state, the EDL mode can become bugged out so it's not possible to put TWRP, Sideload Firmware, or manually put the phone into EDL Mode the usual way to use MSM Tool etc..the phone becomes an absolute paperweight Which the bootloader is "unlockable in that bricked state!"

@Rootk1t And thanks man, glad you liked the guide. Did you happen to brick your 8T?
This guide could be used for other variants btw I just wrote it out for the Global version for now.
