So sir where do I put these?
You need to research more and understand the process. Whatever batch file u use it whatever img you want to flash they all need to be in the same folder. Either run the bat or open a command line in that folder by holding shift and right clicking then select open command prompt here.

I work a help desk all day, I'm tired. This place is a place where people learn to help themselves, I'm not hand holding anymore. You really need to learn the basics before you brick your phone.

OTA updates seem to be broken after using this guide. My latest security patch is February 2019. I've attempted to initiate an OTA update but it says I'm already up to date. Any thoughts?

I'm trying to flash the patched boot.img for MR1, and I'm getting the following error using fastboot:

target didn't report max-download-size
sending 'boot_a' (20768 KB)...
FAILED (command write failed (No error))
finished. total time: -0.000s

Any ideas why? Fastboot detects the device with the correct driver installed.

I'm having a similar problem where the phone is being seen by the computer but when I try to reflash to stock software it goes and says waiting for device.

I finally got things to work by using a laptop without USB 3.0 ports. The phone doesn't seem to like them, at least on my newer laptop.

Razer phone 2 trouble

Hi All,

In the best interest to provide clarity I'm creating this quick and easy tutorial on how to root your Razer Phone 2 after the Pie Upgrade. Please send me any feedback to improve this post, we need to build up a strong community.

*As usual, I'm not responsible of any damage or brick to your phone, do it at your own risk.

Pre-Requirements:
-Be sure to have at least 70% of charges... or plug your phone to power
-Backup anything you consider important
-Already installed Pie Upgrade via OTA or Side Loaded​

-Enable Developer Options
• Open Phone "Settings" and scroll down.
• You will see an option "Build Number".
• Simply tap on it 7 times to enable it on your Android Oreo based device.
• Your device immediately display a message on screen that will say "You are now a developer".
• The Developer Option is now available in the Settings>System>Developer Options. Enjoy!​

- Install Android Drivers (https://developer.android.com/studio/run/win-usb) and ADB, I personally recommend -[TOOL]Minimal ADB and Fastboot [2-9-18] - https://forum.xda-developers.com/showthread.php?t=2317790

-Unlock Bootloader
• To enable OEM unlock, go to Settings > Developer options and check Enable OEM unlock
• Using ADB commands reboot on bootloader​

adb reboot bootloader

• After reboot completes follow phone menus and select "UNLOCK BOOTLOADER"; accept all warnings, after restart you have completed the unlock.​


Root and Installing Magisk
Since our phone doesn't have a proven customer recovery fully working (Ex TWRP) Magisk needs to be installed by manually patching the device boot image.

Making leverage of Warrior1988 post [Root Magisk Pie Update For Unlocked Devices] all credits to him. Download the image from his post


• Boot in fastboot mode To boot into fastboot, press and hold the Power button + Volume Down Keys for few seconds; Copy the image on the same folder as your ADB and Run the following commands:

fastboot flash boot_a boot.img

fastboot flash boot_b boot.img

fastboot reboot


Install Magisk Download the apk and install it as usual on your RP2, that should be all.

DONE!!!! You now have a unleashed the beast! Please send me any recommendations to improved this guide.


i don't understand, i typed adb reboot bootloader my razer phone 2 did jump to the bootloader screen, then i type "fastboot flash boot_a boot.img" into the cmd, but nothing happen ????

Is the patched boot image in the same directory as your fastboot?


Yes, it is.
I did some research and find out that the phone have to had TWRP recovery to install magisk, and to install TWRP i have to flash the "Arter97 kernel.img". But then the problem still there...<waiting for device>
Here is the link to that Forum : https://forum.xda-developers.com/razer-phone-2/how-to/root-t3875237
When i type fastboot flash boot arter97-kernel-*.img the powershell screen goes to <waiting for device>.
In Devices manager, My phone is recognized by windows as " Android bootloader interface" (already install the driver) and also able to unlock Bootloader by my Windows 10.
It doesn't show any series number when i type "Fastboot device", but with ADB devices, it shows...(?)
Is this a problem of connection ? or not ?

Please help

EDIT:
Is it because of my USB port ? I have done some research and some say it's because of the USB port 3.0 and should use 2.0....or is it because of the cable ?
My PC is an MSI with windows 10, all USB ports are 3.0.
There was a threat about USB port 3.0 with flashboot problem, and there was a answer that propose to disable XHCI in the BIOS/Advance tab so the USB port will use 2.0, i have doned that, and its not working.

Device : Razer phone 2, android 9.0, Cheryl2
PC win10 MSI

This is essentially what I get, my system recognizes my device and I recognized the shellprop slot as _a yet I have no avail. I have tried every slot on this computer (3) and multiple cables and none have worked. I hear that apparently USB 2.0 is preferred? Or does anybody know what I could do to troubleshoot? Thank you.

Have you tried a different fastboot executable? Uninstall reinstall drivers? Yeah I use a standard microusb with a C adapter on the end and it works great.

    Your link has everything necessary for this step, right? Direct link to version 1.4.3 is here: https://androidfilehost.com/?fid=746010030569952951
    Or are drivers and ADB two separate downloads?



    I assume this is where we plug our phone into our computer?



    For anyone dumb and new like me, I think this is with cmd.exe in Windows. Win+S -> type "cmd" (without quotation marks) and hit enter. Once open, you want to navigate to ADB, which you've already installed via the above instructions.

    So your cmd will say:
    C:\Users\YourName>

    And you want to get to ADB, so you'll type "cd" (without quotation marks) which means you want to change directories, and then "cd adb" (if its in C:\ directory) or "cd [whatever the path is to the ADB folder]\adb"
    Assuming it was directly in C:, you should see something like:
    C:\adb>

    Now you want to type "adb devices" to make sure it sees your phone is plugged in. You should see: "list of devices attached - [model] device" or something.

    Now you're ready to go with the instructions starting at "adb reboot bootloader." If I'm wrong about this, someone less new and dumb than I am please correct me.



    I'm confused on this one. The first one has "flash*boot_a," but the second one has "flash boot_b" without the * symbol. What does the * do, and what happens if we mess it up? Sorry if that's a dumb question.

    fastboot flash boot_a boot.img

    fastboot flash boot_b boot.img

    fastboot reboot

    yeah i found out what was wrong, finished flashing the .img files only to get a bootloop cause i flashed MR1 .img files to my phone (MR2) i need to get the .img of build P-MR2-RC001-RZR-190914.3123 but the file is 2 GB and i have a 5KB/S download speed :/ all i need is the .img from it, could you possibly provide me with it? i cant find it elsewhere

    Here you go: P-MR2-RC001-RZR-190914.3123-boot.img
