ROG2 no fastboot? - ASUS ROG Phone II Questions & Answers

Hi all, I bought a used ROG2, received it by post and found out that bootloader was unlocked, and running WW Android 9 on a CN signature phone. Tried various times with ADB to flash another stockROM, failed because it doesn't seem to have fastboot. Looked up the manuals, and followed it to the letter, to lock bootloader, flash stockROM, and change signature of phone to WW..... This is the 12GB/1TB version, imported from somewhere in Asia. With ADB it sees the device and produces the code, fastboot didn't seem present.... In developers option the "unlock OEM" is NOT present.... Anyone any ideas?
Thank you in advance, brgrds Erik

You run fastboot mode, press Volume+ and then POWER 2-3sec

Hi Ircio36, to get into bootloader I knew already, but thank you. My problem is that no computer with 5 different cables is able to see the device in fastboot. Previous owner sold me the phone with unlocked bootloader, Android 9, software WW with phone signature CN. No way to get the bootloader unfortunately. Brgrds Erik

The computer sees fastboot mode on the left side Type-C port

Know that as well, together with not using the original Asus cable. Absolutely no luck with it, it's like fastboot doesn't exist

How to switch the phone to fastboot mode, the computer must see the phone. If it does not see then you have a damaged cable or old drivers on your computer

Thank you first of all for your support! Have used 5 cables, latest ADB and USB drivers for this phone, still no luck.....

do you want to have WW versions do you have CN? That's right?

I would like to change signature of phone to WW, is now CN. Software is WW which previous owner put on

Unable to Flash Custom Rom using Hasson 2000's Tool on HTC one (M7)

Hello everyone,
I bought an HTC one off ebay, having in mind I would flash custom rom on the device which I prefer for obvious reasons. But each time I open Hasson2000 Tool to get ID token I get this error in command prompt below:
*daemon not running. starting it now on port 5037 *
*daemon started successfully *
'error: device offline
I have tried searching for solutions but I cant get one to actually fix my own issue, I do know the HTC bootloader has been unlocked and rooted because I can boot to bootloader menu, boot to recovery mode and on top on the screen it says *****TAMPERED***** just below it says ***UNLOCKED*** I figured the previous owner tried locking bootloader before selling it off.
I noticed other commands dont work like reboot device on the tool probably because of that error or my htc is not recognised am not sure. am running Windows 8.1 Pro on my laptop.
What I have done so far
Rebooted phone several times
Rebooted my laptop several times
Unplugged and plugged in usb cable
Used different usb ports it recognises my htc because I can view my SD card or transfer files between laptop and phone.
Please guys I neeed your help with this, thanks.

Depending on the carrier the device was made for and the one you use, OTA updates may not be an option. If it is a carrier device then updates will be pushed OTA from the OG carrier. IF you use a different carrier then you wont get OTA. And to be honest they are over rated and cause more issues then anything else.

What about using the command prompt instead of a toolkit? No disrespect to Hasson2000, but toolkits aren't ideal imo
In most cases, ''device offline'' is caused by an outdated version of the android sdk or a bad usb cable/usb port (btw use usb 2.0 ports).
Also in windows devices manager, your phone must be listed as Android usb device ---> My HTC. If not, you have drivers issue.
If your phone still boot normally, just copy the rom inside the sdcard, reboot in recovery and install it. I will highly suggest you make sure adb and fastboot works correctly before as they will be required if something goes wrong when installing the custom rom. Also make a nandroid backup of your current config before flashing the rom and make a copy of that backup on your computer.

Well actually I used command prompt since the Hasson2000 tool did not work, Yes my HTC displays under device manager when plugged in. I think its my adb that is out of date.
How do I update my adb?

Stuck in fastboot, Bootloader is locked! Need help!

I have flashed my device without enabling debug mode. I have used Mi Flash to flash my device. After a reboot, I got stuck on fastboot, but bootloader is locked. Also, I can't enter on twrp...
If I do: fastboot devices, my device is recognized by PC.
If I do: fastboot oem device-info, all information is false except device tempered...On "device unlocked" it shows false too... It means that bootloader is locked.
if I do: adb devices: under List of devices attached, there is no device.
What should I do? Please help me out.

Bro it'd be highly appreciated if you could guide me what that is and what will it do ? i opened the website and it says you must have officially bootloader unlocked.
If your bootloader is locked, you need to unock it first before you can do anything. If you had registered your device with your Mi account, you can still do that following this description:
https://www.stechguide.com/mi-flash-unlock-tool-to-unlock-bootloader-of-xiaomi-devices/
If you did not register your device before, there is no way to get it repaired but by an official verndor or Xiaomi customer support.
Sorry if that is bad news for you.

Good phone, but without support within your country, there is nothing you can do now.

Cannot update my K20 Pro - please help

Hi all,
I bought my K20 Pro on Ebay and later found out, that the seller has unlocked the Bootloader and installed a Global Beta Rom on it. In detail it is the Miui 10 Global 9.5.31 Beta, Android version 9 PKQ1.190223.001. Now I do not get any OTA updates and have a security level still of May 1, 2019. If I try to manually download and install the latest update I do only get error messages. Can someone help me to solve this problem pls.
Flash firmware via fastboot and mi flash tool but don't re-lock your bootloader because apparently your phone is china version and after locking bootloader with global rom you'll brick your device. Next time double check from who you're buying a phone.

It depends on your OS. But mostly you need to have adb/fastboot drivers. Check also Device Manager if it's correctly installed.

Makes no difference.
Boot the phone in fastboot mode and connect it to the PC.
Check your PC can see the phone correctly with the
Code:
fastboot devices
command. You should get a response showing an ID number of the connected phone.
If your not sure about the above 2 steps, do a bit of research. You'll very quickly find informally about these things.
If you get a valid response to the above, then the Mi Flash Tool will be able to see the phone now.
You might be able to update from Global Beta to Global Stable using the local update method since your bootloader is unlocked. There's also no chance of accidentally relocking your bootloader and bricking your phone but since you are supposed to be running the China/India ROM with your hardware you might get an error message.
I think flashing via MI Flash is a better idea because the shop that scammed you might have also installed malware or Spyware on your phone in addition to the Global ROM. They also could have installed a modded ROM coded to prevent MI Flash from recognizing your phone.

Not recommended at all. Very likely to have issues afterwards.
It's considered safe to do this going from stable to beta, but it's recommended to fastboot flash if going from beta back to stable.

(HELP) Pixel 5 bootloop after reversion to stock from beta

Hey Everyone,
I'm looking for help. I tried reverting my pixel 5 to stock from beta and am stuck at the boot screen with " your device is corrupt. It cannot be trusted and may not work properly."
I've spent days fiddling with it, and cannot get anywhere with the google repair website because it's saying my bootloader is locked. I don't understand how I purchased it unlocked. Anyway, I cannot get into the settings to unlock the bootloader. It's been a long time since I've been a tinkerer but I do have all the software downloaded to do so. I cannot get my PC to recognize the phone in the command prompt window to try and sideload a software install.
Has this happened to anyone and is there a solution out there somewhere?

Buying it "unlocked" means you bought it free of a carrier, such as Verizon, who lock the bootloader, and can't be unlocked.
But you still need to unlock the bootloader, it comes locked, for security reasons. So if you never unlocked it, it's locked.
I haven't installed beta 12 yet.
Do you have the latest SDK tools? (adb, fastboot, etc)
I was under the impression though, that you can't downgrade with a locked bootloader. But not sure.

This probably isn't of any help now, but going forward, it may be. In Developer options, you can enable 'OEM unlocking'. As you can see now, it may well be a very good idea to enable that **before** you start messing with the phone, because if something does go wrong (as it has for you), then you can (hopefully) still get to fastboot and do 'fastboot flashing unlock'.
So, knowing this, you may want to keep an eye out for some tool or something that will allow you to possibly turn on oem unlocking (because your device won't boot).
Another thing to try is switching slots and see if the other slot boots? If you can get to fastboot try; fastboot --set-active=(a or b), then fastboot reboot. (If you don't know which slot is active, do 'fastboot getvar all', in the output it will tell you which is current.
cheers
Your bootloader being locked should not affect your ability to restore factory images/OTAs from Google. They are signed by Google and will pass the signature checks. You should try to download the latest factory image (either 11 or 12beta) and flash it via recovery => adb sideload.

My rog 3 tencent version is not unlocking bootloader, bootloader is failed to unlock your device plz help me

My rog 3 tencent version is not unlocking bootloader, bootloader is failed to unlock your device plz help me
How did you attempt to do it? Steps please.
Same issue here. Previously I was just downloading the Unlock Device app here and running it. (I already had developer options enabled) and the device would reboot but not do anything (I reckon I tried 10+ times). Since then I formatted the device and tried again and got the same results so I set the device backup normally today (running build 18.0410.2108.158) and tried it again (with and without developer options enabled as I forgot to check) and I just get a standard error message saying it couldn't unlock my device and to try again later. Same result multiple times. I don't see any option for OEM unlocking in Dev options which I see some people mention. I'm updating to the latest OS I can see in the link I provided and I will try again after installing that.

Hello
Your phone has already been unlocked earlier and has the flag removed. Someone blocked it again for sale.
So you won't do anything with Asus tools.
I recommend the EDL mode
