[TUT] [MAC] Unlocking your Kindle Fire HDX 7 Bootloader

Hello, welcome to my to my guide on how to unlock your Kindle Fire HDX 7's bootloader. This guide is for mac.
I will be nicknaming the Kindle Fire HDX 7 as thor.
I will be assuming you have TWRP and flashed the .3.2.3 bootloader upgrade and ADB/Fastboot.
Steps:
Go and get python 2.7.X (X = Doesn't matter.)
Open up a terminal window and paste this command in:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Click to expand...
Click to collapse
Now, press enter.
So, now what to do? Well, heres the next thingy
Type this in the terminal:
brew install gcc
brew install mpc
brew install mpfr
Click to expand...
Click to collapse
Done.
Now type:
pip install gmpy2
Click to expand...
Click to collapse
BAM! You should now have GMPY2 installed.
Now, download this:
cuberHDX.py
Place on desktop.
Open up a ADB Window and type:
./adb shell
cat /sys/block/mmcblk0/device/manfid
cat /sys/block/mmcblk0/device/serial
Click to expand...
Click to collapse
Now, type the last 2 digits of your manfid and serial.
M = last 2 digits of Manfid Serial = Your serial code
MMSERIAL
Okay, now open up a terminal window and go to your desktop/folder with cuberHDX.py
Type in this:
./cuberHDX.py 0xMMSERIAL
Click to expand...
Click to collapse
This will make a file called 0xMMSERIAL on your desktop, if not do a search for it on your computer.
Next drag that file into where your fastboot is
Now, type in this:
./fastboot -i 0x1949 devices
Click to expand...
Click to collapse
Your device should pop up.
./fastboot -i 0x1949 flash unlock 0xmmssssssss.unlock
Click to expand...
Click to collapse
Next, wait 5 seconds.
Now, check your screen if it says UNLOCK CODE CORRECT, or something similar. If it doesn't, make a new file with the correct MMSERIAL Code.
./fastboot -i 0x1949 reboot
Click to expand...
Click to collapse
BAM! you now have a unlocked bootloader THOR.
If any problems please type in the comments below.

Where can I find that particular bootloader? It's not coming up in my searches.
Many Thanks in advance!

Here. Make sure you understand the prerequisites before flashing update (or risk a brick).

I should have left well enough alone. Bricked it.
Thought I have all the requisites.
Welp, now I have new search term! Unbrick
I'm an idiot sometimes.

Judging by your sig, you must of had 13.4.5.2 installed. You can't unbrick now, cause you fried your device not reading my guide right.

Little help please
haven't done anything on android for a while but I'm not completely hopeless i promise. i understand everything necessary in this guide but i am a little confused, i have 13.3.2.2, what is the best procedure to get to a rooted 3.2.3 and TWRP installed? i don't want to accidentally go over 3.2.3 and not be able to unlock.
another note, are we talking 14.3.2.3 or 13.3.2.3? Mine is 13.3.2.3, just an fyi

Make sure your device is in airplane mode so it won't attempt to download any OTA updates in the background.
For root access, you can just use towelroot. From there, you can find instructions for TWRP on this thread. thor is the codename for the HDX 7, while apollo references the 3rd generation HDX 8.9 (so you'll obviously want the first one). Alternatively — instead of using adb — you could also flash it straight from the device itself using Flashify.

Thank you for the response. How do i run towel root, without internet access i can't go to the site and i don't have a file explorer to open the apk if i add it manually?

You should obviously be fine if you enabled WiFi for a few minutes, but you can install apps directly through adb.

Getting there
So i have rooted and installed twrp... i am to the fast boot step. I enter the first fast boot command and it does not return anything. just goes to a new line like nothing happened.

Would've helped if i actually put it in fast boot mode. I now have an unlocked boot loader. Thank you both for your help, it is greatly appreciated.

I found 2 links:

Bro, your Sig says youre running CM13 - Im on the pre-installed CM12.1 so will that make any difference?
By the way. what extra features does Rooting give to the Zuk?

Yes now I'm on CM13 but I did my root on COS 12.1 before, KingRoot works on both ROMs for me.
Yes, for me rooting gives a lot as I'm using Xposed modules like Amplify and Greenify and some other nice software, but if you don't find it useful don't do it Read on internet what ROOT gives, it's not useful for everybody, but for me is essential.

Hey guys,
I've managed to root my Z1 with KingRoot. Just wanted some confirmation that if I install twrp and unlock the bootloader there should be no problems flashing a custom rom right?

Impossible to root?
Hi guys,
I have been trying to root my device for 2 days, with no success.
I have tried 2 different Windows computers, just to make sure that I wasn't making any mistake with the drivers. The problem is that I never get to see my device when I launch the command "adb devices". Developer option is activated, ADB modeas well, OEM unlocking as well. Driver installed (Google generic one and tried also ZUK USB drivers 1.0.5), I get to see 3 devices in System Properties:
- under portable devices
E:\
Z1
- under ShenQi ADB Devices
android ADB interface
Can anyone suggest what should I do?
I don't get the RSA Authentication authorization request from the device once I plug it in....
Really no idea of what to do. Should I try kingroot?
Thanks in advance
Marco
EDIT: CyanogenOS 12.1 YOG4PAS7DF, security patch level 1-4-2016

Anyone who can support me?

Use the tool in the link below and follow instructions. It will do everything for you and install a custom recovery and let you install su.
Would recommend uninstalling all previous USB drivers and start again.

Possible to root when on 7.1.2?

I was updating my phone to try and match a tutorial, got up to the May security update (n2g47O) and found out the tutorial was for windows. I'm running Linux currently, so I can't use the fancy root toolkit.
Are there any decent tutorials that list which files to grab and where to grab them, as well as the step-by-step? I really like this phone, but I'd like to have more freedom with it. At the same time, I'm afraid of following ancient tutorials and bricking my phone. I have -some- experience with softmodding via hacking handhelds, but this is the first time I've messed around with a phone.
Thanks in advance for your help. I saw the suggested threads, but none of them seemed to directly answer my question.

I was reading through the guide, I just wasn't sure if it was compatible with 7.1.2's May build, or if I should update to the newest build, or what. It didn't look like it had been updated in a while.
If all I really have to do is follow the guide step by step, sorry for being dumb n wasting time.

You will be fine with the guide doesn't matter which firmware your flashing. He actually States the steps that won't apply to you being in newer Android version, and ones that do apply being on 7.1.2.

Thanks, but I don't think the steps are accurate for Linux. I tried the fastboot flashing unlock in Linux' terminal and it just lists a series of commands.

Try following one of the many guides for Linux on YouTube if you can't understand the guide completely. I sometimes struggle with worded guides so a video will probably help you out.

I'll scrounge around and see if I can find better guides. So far, I haven't uncovered one for Linux in 7.1.2. I'm hesitant to follow one for 7.0 because I have experience modding gaming consoles and if the version numbers don't match, bad things can go down.

I'm not familiar with doing phone stuff from Linux but if you know how to flash factory images them just grab the one that matches the tutorial and revert. Once you are rooted and where your want to be then upgrade through TWRP.

Version of OS is irrelevant.
You need to fully set up the phone and enable developer options.
You then need fastboot and ADB for the OS you are using. (I use a Mac).
You will want to install TWRP and Magisk. Magisk will provide the root functionality and completely hide it so even AndroidPay will work.
https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445
Good luck

I have found in my installation of Fedora linux that once the phone is in bootloader mode, you need to use
sudo ./fastboot flashing oem unlock
then to flash images
sudo ./fastboot flash boot boot.img
etc.

Beginner Tutorial - Unlock Bootloader + TWRP + Root

Hi everyone, I just want to share this tutorial for someone like me (NEWBIE, NOOB, BEGINNER, ZERO KNOWLEDGE).
ALL CREDITS TO THE RIGHTFUL OWNER.
PRE-REQUISITES
- Laptop
- Applications, .img files (https://mega.nz/file/igphSCTD#OybJo9t1zwvJ0bdbAcN2BCqxWXAfHdhk3JFB4_5xkVc)
- Your Nubia Phone
ENSURE THAT:
- You installed the application and driver (Minimal ADB and Fastboot & the driver from your Nubia phone).
- You updated your OS in the latest version.
- You UNLOCK the developer option (setting>>about phone>>tap 7x the build number) and you switch ON the OEM unlocking & USB Debugging.
- You approved the RSA request in your RM5G
NUBIA RED MAGIC 5G UNLOCK BOOTLOADER
1. Connect your Nubia in laptop, in your laptop, open Minimal ADB and Fastboot and type the following:
a. adb reboot bootloader
b. fastboot oem nubia_unlock NUBIA_NX659J
c. fastboot flash recovery recovery-TWRP-3.4.1B-0324-NUBIA_REDMAGIC_5G-CN-wzsx150.img
d. fastboot flash vbmeta vbmeta_BL_skip.img
e. fastboot flash modem NON-HLOS.bin
f. fastboot flash parameter parameter.img
2. Go to your RM5G, select reboot to recovery
3. It will reboot in TWRP twice, in the 2nd reboot it will stay in TWRP, change the language to English and select the keep read only.
4. Go to WIPE option, then select FORMAT DATA, type yes
5. Press home button, then go to REBOOT, select REBOOT to RECOVERY
NUBIA RED MAGIC 5G ROOTING PROCEDURE
6. Go to ADVANCED, below there are list, select INSTALL ROOT.
7. Reboot your RM5G.
At first, my RM5G restart twice, I was afraid that it was bootloop, the 3rd boots, it booted up and its rooted already.
Also, when I first registered my Finger Print, it’s malfunctioning, so I just deleted the OLD FP , register NEW FP and it works like a charm.
Now, I managed to flash the wonderful kernel of @mslezak.

Great job bro !

Note for those that don't know how to enable developer options - go to settings, about phone, click build number 7x. It should take you right to the Developer Options menu. Nice clear concise guide by the way! Glad someone wrote a simpler one than the one I wrote initially, only so many hours in the day.

I've been trying for days to download the MEGA zip, but no matter what I do it always stays on 0% and gives me an error. I tried on different browsers, on different computers, and using the desktop app, I even tried with the mobile app with no luck. Could someone please share a mirror or another link, please?

Nevermind, I was finally able to download the file, my solution was to use chrome instead of firefox and close every window except the mega one... I left it like that for a couple of hours and it finally downloaded it.

Possibly a stupid question, but are there any downsides to this other than the risk of bricking?

You can hide the Magisk (setting/select the apps/then hide magisk) so it will not detect that you are rooted.

Hi,
2 questions. First of all, does this method work for all of the 5G phones? As in the European version etc. And second of all, will the phone brick if you update it via OTA, or do we need to do this method every time?

Hi Guys, first of all thanks for awesome tutorial. Got it rooted and enjoying the perks. However, some issues do exist. 1. The phone has detected a new update v4.09. Will the root be deactivated if I update the system? Second question, my banking app is detecting the root and does not want to start. I did set magisk manager to hide it from the app and restarted the phone even, but no luck the app still sees the root. Any solution for it? Thanks all

[SM-G950W] Running official Android 9 on Samsung S8, help me understand my options (root, custom ROM)

Canadian SM-G950W Snapdragon Samsung S8 on Android 9 user here.
I've been reading a lot trying to figure out what I can do with regards to rooting & installing custom ROM. But the available info is confusing and contradicting.
Could anyone please answer my questions below?
1. Can I root S8 that is running Android 9?
I've tried naively to flash CF-Auto-Root with Odin , but got an error.
2. Knowing that bootloader is locked I thought I could downgrade to Android 7 and unlock the bootloader
Paid for SAMMOBILE firmware, but Odin failed to flash Android 7. Then I read somewhere that you CAN NOT downgrade Samsung phones. Is that the case?
3. What is the roadmap for flashing custom kernel, ROM and rooting SM-G950W Snapdragon Samsung S8 on Android 9?
At the end of my wits here... Thank you in advance!

Use Magisk. Flash TWRP, then install Magisk in TWRP. This won't be possible if the bootloader cannot be unlocked

Depends on the binary version, the screen text in Download Mode should tell you. You can't downgrade the binary, so if it changed from 3 to 4 (for example) and is currently on 4, you can only flash binary 4 firmware, but you can't downgrade to 3.

I'll try to put this simply:
Enable OEM unlocking in developer options
Unlock bootloader (wipes data)
Boot device, set up Google/Samsung account, connect to the Internet
Perform a manual update check, do not download update
Check to ensure OEM Unlocking is still visible
Put device in download mode and flash TWRP; immediately boot TWRP, do not allow device to reboot into system, otherwise it will restore the stock recovery
Make sure you flash the Multidisabler in TWRP to disable encryption and recovery restoration
Flash Magisk in TWRP to gain root
Boot into system and set up device, install the Magisk app to manage root.

I would leave it on Pie. Anything below that has nasty vulnerabilities like X helper.
If you want more performance optimize it with Package Disabler or adb edits.
If that doesn't get it, get a N10+, a huge performance and cam increase.

> Use Magisk. Flash TWRP, then install Magisk in TWRP. This won't be possible if the bootloader cannot be unlocked
But the bootloaded IS locked on Android 9, thus Magisk/TWRP can't be installed. Or did I get something wrong?
And since @blackhawk just said to leave it on Android 9 - can anything be done at all?

But the bootloaded IS locked on Android 9, thus Magisk/TWRP can't be installed. Or did I get something wrong?

Are you saying it can't be unlocked? Or simply that it is not unlocked?
The bootloader unlock has nothing to do with the Android version. Whether you can unlock it might though.

And since @blackhawk just said to leave it on Android 9 - can anything be done at all?

Blackhawk is a cranky old curmodgeon, don't listen to him. Totally kidding, he's a smart guy.
So let's focus on Step 1. Enable Developer Options, do you see the OEM Unlocking toggle?

@V0latyle
first of all, thank you for your time and patience.
nope, no such thing under Developer options. neither grayed out, it's just not there.

Okay, so you're on the latest update. See if you can download and flash CSL1
If that works try AQD9
Next time you're in download mode, either take a picture of your screen or post what it says for SW REV or RP REV

consider downloaded - 6min left.

should I use standard ODIN to flash it?

Bad news but OEM Unlock does not exist on North American models. So you are out of luck unless you have a low bit number which then you can go to @afaneh92 for US/Canada Samsung BL unlocking
