adb reboot bootloader/fastboot mode not working on Realme U1 - Android Q&A, Help & Troubleshooting

I have a Realme U1 that I am trying to root. I already have the patched boot image. When I try to go to fastboot mode, it goes into ColorOS recovery mode. There is no option for fastboot in ColorOS recovery mode. Tutorials say that to go in fastboot mode in Realme, I have to do Power + Volume Up instead of Power + Volume Down. Tried that. Didn't work. Just booted normally. Adb is working as usual. BUT when I tried 'adb reboot bootloader', it doesn't work. But when I try 'adb reboot recovery' IT works. At this point, I don't even know what to do. Please help.

I made the question wrong. It is supposed to be:
When I try 'abd reboot bootloader', it does not work. But when I try 'abd reboot recovery', IT works to get me into RECOVERY mode (which I mention because this is proof adb works).

right, seems fastboot mode is disabled forcefully then.
you can unlock bootloader with mtkclient
Code:
python3 mtk da seccfg unlock
you can dump partitions and flash TWRP + vbmeta_disabled.img
Code:
python3 mtk rl out
python3 mtk w recovery twrp.img
python3 mtk w vbmeta vbmeta_disabled.img
vbmeta_disabled.img can generated from avbtool.py or you use copy of out/vbmeta.bin from phone dump and change a single byte with HxD editor
What is 02 in the magisk patched vbmeta.img?
According to the Additional Info given for rooting the Android device that doesn't have ramdisk but can be rooted via recovery: we need an empty vbmeta.img and I am trying to check what it actually

Gonna try this. I hope this will not wipe my data. Will it?
Edit: I dont wanna do any of the aforementioned things. I want to just root and/or enable fastboot mode. How do I do that?

I don't know how to enable fastboot, but for rooting the aforementioned things are recommended.
factory reset is mandatory for rooting. except you use vulnerabilities that allows rooting on locked bootloader.
on old devices like this it might possible to flash magisk patched boot.img on locked bootloader, as avb/dm-verity implementation was weak on mediatek devices up to Android 7. to try this, you need a flash tool like mtkclient or SP Flash tool.
It's now easy to bypass MediaTek's SP Flash Tool authentication
A group of developers has created a Python utility to bypass the authentication routine of MediaTek SP Flash Tool. Check it out now!

Can't root rui 2.0 (Android 11), and can't install custom recovery except "los recovery" but can't do any thing with it just wiping cache and data partition.
do not try to flash custom recovery on realme ui 2.0 , it will brick your device
I need to ask, this guide will work with A88/A89 update?
sorry for noob question - I'm not familiar with mediatek devices and rooting/flashing stuff. Currently I'm running crdroid. What steps are neccessary to get rooted stock? is it:
- flash original firmware (how? SPTool?)
- issue all the commands from OP?
Or do I need anything else?

Yes. Just flash the original firmware using SP Flash-Tools. However, youmust make sure it is the full 7-8 GB ROM, and not an OTA file. Also, ensure that you are flashing the correct ROM for your model. If your model is an RMX2155, you'll need to follow this guide steps 1-through-to-10 (inclusive):
[GUIDE] REALME 7 RMX2155 GLOBAL BOOTLOADER UNLOCK
WELCOME, ALL. After a very tiring process of swapping between ROMs and changing regions, APKs, et cetera, we have finally been able to perfect the method for unlocking the bootloader of the RMX2155! This is a detailed guide aimed to give you an...
forum.xda-developers.com
If it is any other model, just do what is said to work. Unfortunately, I don't know much about the other versions.
thanks the explanation.
I've found a 2155 ROM or at least a file that's said to be - ie. I've found a file 'RMX2155export_11_C.09_2021070809260000', extracted that, there was a huge file 'RMX2155export_11_C.09_2021070809260000.ofp' inside; using oppo-decrypt from github I've got bunch of files with names that seem to be SPFlashTool ROM.
Assuming it's a proper ROM: if I have already unlocked the bootloader, do I have to flash the rom and do the 10 steps from the tutorial or could I replace recovery.img and magisk-patched boot.img and flash rooted rom immediately? Sorry if it sound noobish, but I don't want to brick the phone.
I'm curious to try to go back to stock ROM for a while, because of call quality (I believe changing it to Vietnam needed for unlock made the call quality worse) and to check the camera and it's libraries - I'm running crdroid, photo quality is disappointing no matter what GCam/settings/tweaks I use and there are only imx682/imx471 libs on the phone there are samsung libs, but diagnose apps like aida show the main sensor is imx682, but the EU version of realme 7 is said to have different back camera sensor (GM1). Not sure if RMX2151 ROMs would include proper GM1 libs if that's true about sensor differences between RMX2151 and 2155.

LG K61 (mt6765) root?

Hello guys,
I'm looking root options for this device.
Phone's bootloader is probably locked,since there is no fastboot mode.
I have patched boot.img made by magisk manager for A slot(don't know if need for B slot too?)And probably i need patched vbmeta which I don't have it.
I see there is in firmware kdz Efuse image too,I'm wonder if I format this partition in with special transsion tool,could it unlock bootloader?
Thanks forwardly for answers.

I'm pretty sure Fastboot works if you installl the matching Android USB Driver provided by LG on computer.

No, those drivers would help if there would be a fastboot mode.
But it just isn't available. It just boots to normal mode what ever you try, eh?
That is normal for most of the LG phones...
I'm looking for days on how to unlock bootloader on this phone,but the big problem is there is NO fastboot mode installed.
Is there anyway to workaround to unlock or to enable fastboot mode?
Is there any hidden method with buttons or something to enable bootloader?
This model chipset is mt6765 and what I have tried is I patched both boot.img from A and B slot and flashes back with Transsion program but aftet first start it triggers dm-verity.
I also tried formated Efuse,LAf_a and Laf_b and VBMeta partitions,flashed two boot.img patched and after that it is again trigger dm-verity,but HOW???
I'm having the same problem, i have an LG K51S, when i run
Code:
adb reboot bootloader
its reboots to the normal state, idk what to do, if you have any information please contact me.
Thanks
just subscribing to the thread, I need to root as well. No info yet found. I need root

Adb reboot fastboot and you'll be in fastbootd which removes oem commands but I've been working with the stylo6 and K51 which I have the ability to unlock the bootloaders and flash magisk patched boot.img successfully to gain root access.

Hi, I have a LG K52 and they have the same chipset as LG K61,
I'm having trouble now trying to root and unlock it, can you please explain how you did ?
The only thing I've been able to so far is to get into fastboot and it's in a very very very dirty way, since adb reboot bootloader won't do the trick I had to type adb sideload radomimage.img to get into recovery menu and finally reach Fastboot, but nothing happens when I try fastboot oem unlock or fastboot flashing unlock or anything else
First the adb command is adb reboot fastboot and you can't unlock the bootloader in fastboot, the tool mtkclient from github will do that, i have a group that I sent you the link to in a message, there are instructions and support in there with now almost 200 members. We are helping unlock nearly every newer LG model and many others.

Development [Stock]-[Recovery] - Boot Image stock recovery - Unlocked Nord N200 5G

Attached is the stock boot image pulled via payload dumper for the OnePlus Nord N200 5G. It is from the full OTA zip - Official Build 11.0.2.0.DE17AA dated September 2nd 2021.
It seems quite a few folks are trying to get ahold of this. *Download link at the bottom*
I AM NOT A DEVELOPER!! I am just posting this for those who need the image file.
The guide to install this is pretty simple. If you have previously rooted the device then you most likely have installed the partially functional version of TWRP for the device. If you have, then you can use the same method for installing TWRP to install the factory boot image. Keep in mind that if you have installed Magisk to the device then you may encounter problems. The following pre-requisites should be followed prior to flashing.
1.) Do a complete uninstall of Magisk if you wish to no longer retain root. There are no guarantees this will work if you keep Magisk on the device. Since Magisk changes the system binaries, stock recovery may not work properly.
2.) Make sure the bootloader remains UNLOCKED! Attempting to lock the bootloader WILL cause an error message that the "Device is corrupt and will NOT BOOT"
3.) Make sure you have enabled USB debugging and your PC can recognize the device. You can do this by booting up the device normally and use the command prompt
adb devices
If the device is recognized it will return with your device ID and "device". If you see anything other than the ID and device (such as unauthorized) then please check to make sure you have enabled USB debugging, the device is plugged to the PC and the path to your platform tools of ADB and Fastboot tools is proper in your command prompt sequence
HOW TO INSTALL:
1.) With the device on and plugged in, open a command prompt in the path that your ADB and Fastboot platform tools are located and type:
adb devices
If properly read, ADB should return with the device ID and "device" as stated above.
2.) Now execute the ADB command:
adb reboot bootloader
Wait a few seconds. The device should now boot into Fastboot Mode.
3.) Now execute the fastboot command:
fastboot devices
The device should now read like earlier with the device ID and "fastboot". If true, fastboot commands will be accepted. Also please double check the device state on the phone screen. Make sure the device is UNLOCKED. If so, stop reading this step and go to step 4. If it is not unlocked DO NOT proceed and reboot the device using the volume keys when the word "START" is in green letters at the top and pressing the power key. DO NOT proceed any further. If your device is functioning in a locked state then stop reading this guide and go back to playing minecraft or flappy bird or whatever it is you do with your phone.
4.) VERY IMPORTANT!! Execute the following fastboot command:
fastboot getvar current-slot
The device will give a letter, either a or b. PLEASE remember the letter as the next step will require that letter after the underscore in the next fastboot command. If slot a, type a; if slot b, type b after typing the underscore.
5.) Make sure this boot image file is located in the same folder as your adb and fastboot for your platform tools and execute the fastboot command:
fastboot flash boot_a boot.img (this is for those who are on slot a from step 4) OR
fastboot flash boot_b boot.img (this is for those who are on slot b from step 4)
6.) You are welcome to flash to both slots if you like as no harm will come from doing this, but only the current slot is necessary for it to work. You can also flash it as many times as you like but that's just dirty flashing over TWRP over and over. Finally wipe the cache and reboot by typing the following fastboot commands:
fastboot -w (this wipes the cache - not necessary but helpful)
fastboot reboot
7.) Enjoy stock recovery. You can also use the volume keys to navigate to "Start" and reboot the device or even try "Recovery Mode" to ensure it worked. I would highly suggest that you boot into recovery and factory reset the device, wiping everything.
*This has been tested and works on the UNLOCKED US variant (Basically, if you can update via the OnePlus website and the build number is DE17AA you're good to go.) DO NOT ATTEMPT THIS ON ANY OTHER CARRIER LOCKED MODEL!!
**While the device is back to stock recovery, the chances are very high that any future OTA's (Full or partial) may not load or install if binaries were altered by Magisk. The best thing to do here is to wait for a full package and install via Oxygen Updater or attempt a partial via Oxygen Updater.

I know I'm replying to an old thread, sorry. I'm wondering if any has the stock T-Mob boot image for Android 12, I flashed a boot.img for the unlocked one and now my phone is boot looping. Has anyone pulled the stock Android 12 boot image for T-Mob yet? Or have a link for the full T-mob Android 12 OTA?
Replying to my own reply here, but I found a link to the T-Mobile Android 12 OTA here: https://community.oneplus.com/thread?id=1599362
Using this, I flashed the correct boot image which fixed the bootloop and now I've rooted it with Magisk.
Can you use this method to flash to de2117_11_c.15?

How To Guide [GUIDE][WINDOWS] Bootloader Unlock/Re-Lock, Rooting with Magisk and flashing Firmwares

[GUIDE][WINDOWS] Bootloader Unlock/Re-Lock, Rooting with Magisk and flashing Firmwares​​Introducing this Guide​Hello there and welcome to My Guide for Your Xperia Smartphone. This Guide will walk with You thru the whole Process of installing Drivers, getting an unlock Key for Your Bootloader, rooting with Magisk and even flashing GSI Custom ROMs up to re-locking Your Bootloader and re-flashing Stock for the total Factory Reset. This Thread/Guide is not meant as Wiki n'or will it teach You about Android at all. Inform Yourself using Google to enjoy the total Freedom and Customization of Android... If You can't solve Problems Yourself, by communicating and research, don't touch Your Bootloader!
IMPORTANT:
2020+ Xperias are using fastbootd, and equivalent to fastboot which runs in Userspace (Same as Recoveries).
You can access Your Recovery on Your Xperia by holding VolumeDown (-) & the Powerbutton (Your Device needs to be turned off before ofc). Release the Powerbutton after the Display turned on and hold VolumeDown (-) until You see the Recovery Screen. From there, You can enter fastbootd and fastboot. Labled as "Fastboot" for fastbootd and "Bootloader" which is the old fastboot. You can flash Kernels, Recoveries and other stuff from fastboot. Everything else like System Images (GSIs for example), Product Images, System_ext Images and any Userspace stuff has to be flashed from fastbootd. 2019 Xperias are still using fastboot only...
Fastboot and Fastbootd has nothing to do with SONYs Flashmode on Xperias!

Extract the system.img and the vbmeta.img to Your Platform-Tools
Connect Your Device in Fastboot Mode and use Fastboot with:
(On 2020+ Xperias run: "fastboot reboot fastboot" first after You booted into fastboot)
Code:
fastboot flash system_a system.img
fastboot flash system_b system.img
[Optional] fastboot --disable-verity --disable-verification flash vbmeta_a vbmeta.img
[Optional] fastboot --disable-verity --disable-verification flash vbmeta_b vbmeta.img
fastboot -w (This does Format Your Device and is needed everytime You change the GSI!)
fastboot reboot
6. Bootloader Re-Lock:
Flash the latest Firmware for Your Device with EMMA
Erase all Userdata before You continue (like with fastboot -w or via Recovery)
Just go into Fastboot mode and type in the command prompt (like before in this Guide):
Code:
fastboot oem lock
Wait for Your Device and disconnect it from USB
Done... Continue with Step 7.
7. Firmware Restoring after Re-Locking:
Download and Install the "Xperia Companion" from SONY
Open the Xperia Companion and select Software Repair
Select that Your Device can't get recognized (or is a Smartwatch 3 lol)
Go to the next Page and select the Xperia Smartphone Option
Continue and wait for the Initialization
Press and hold Volume DOWN while connecting to USB (You will see the Green Flashmode LED again)
Continue once Your Device gets recognized and let the Xperia Companion do his work...
Done. Your Bootloader is locked again and almost all of Your DRMs are restored.
So I haven't rooted a phone in a long time. I have gotten my Xperia 5 IV, and I really want to get back into it. Your post looks like a great place to start. However, I have a question, do you think a custom recovery is needed? If so, would you recommend any? I don't see anything about installing TWRP on the 5 IV, and my quick search online hasn't yielded better results.
Anyone know what models can be unlocked? Previous thread says you can't unlock CQ62 (US). CQ44 (Japan) apparently can be unlocked going by same thread, but what about CQ54 (Europe) and CQ72 (Asia)?
Thanks, that's a very helpful guide! I'm now running the latest available Android 13 image for my phone, happily rooted
As it's in the Sony Xperia 5 IV section of the forum it's important to note that you must use fastbootd or you won't be able to wipe the phone. As such, to summarise, the rooting steps are:
- Unlock bootloader
- Download and extract boot.img (on PC)
- Download Magisk and patch boot.img (on phone)
- Reboot to bootloader (adb reboot fastboot) then to fastboot (fastboot reboot fastboot)
- Flash patched boot.img, wipe phone, and reboot
Once rooted you probably want to:
- Install Displax's safetynet-fix to get Google Wallet, Netflix etc working
- Remove unwated bloatware using something like De-Bloater

You can definitely unlock CQ54, as I have just done it.

I never use custom recoveries, personally, as they're another potential point of failure without any real benefit (you can backup and perform updates easily by other means).

Ah, that's very good to know. What are the other means that you prefer?
Just got my Japanese SO-54C and went to follow this guide only to find out "Bootloader Unlock Allowed: No".
However, I just got that changed to "Bootloader Unlock Allowed: Yes" so I will follow this guide tonight and unlock my SO-54C bootloader! Can't wait.
Bootloader is now unlocked. However, no matter what I try, the device is never actually rooted.
I'm using the Docomo firmware (xperifirm) 64.1.C.0.102 and I use UnSin on boot_X-FLASH-ALL-C220.sin to get .img. Then I instal MAGISK and push the img file to the phone. Then I use magisk to patch the img and retrieve it from the /Download folder on the device.
I use adb pull to my desktop and I do the fastboot flash boot_a and boot_b, wipe and reboot. After going through the new phone setup, I use Root Checker and it says my phone is NOT rooted.
Am I missing something?
Edit: couple reboots later and magisk did something (some kind of update) and it says rooted.

I paid for credits on Infinity Online Service - qUnlockTool. The software didn't work, I notified Infinity Team and they gave me a new exe that changed from NO to YES. Then I followed the guide to BLU and root.
Hmm interesting, wonder if it can be used on American devices for the American 4G/5G bands.
How much was it?

$30 USD. But DM me if you want more info as I believe paid stuff is not welcome.
As far as bands, I have no idea. I quickly soft-bricked my device tonight and just got it back (bootloader unlocked but root is gone).
Well I mean unlock American devices for those 4G/5G bands not in the overseas phones. Otherwise a method to unlock the bands of the 256GB overseas model would be better.
I find it funny that $30 for a $1000 (or $700) phone bad, but for the Motorola Droid Razr M where the unlock costs more than the phone itself it's completely fine to talk about.

This is one of the devices that Magsik has to install some early hooks for, so indeed to finish root you'll need to open Magisk and it'll tell you that 'additional setup required' and to reboot your device. Then it'll be rooted.

I use titanium backup and update directly through Magisk or using fastboot.
i never got into titanium to backup my system like i used to with TWRP.....i loved TWRP
Why doesn't anyone try reverse engineering these paid bootloader unlock methods?

[GUIDE][WINDOWS] Bootloader Unlock/Re-Lock, Rooting with Magisk and flashing Firmwares​​Introducing this Guide​Hello there and welcome to My Guide for Your Xperia Smartphone. This Guide will walk with You thru the whole Process of installing Drivers, getting an unlock Key for Your Bootloader, rooting with Magisk and even flashing GSI Custom ROMs up to re-locking Your Bootloader and re-flashing Stock for the total Factory Reset. This Thread/Guide is not meant as Wiki n'or will it teach You about Android at all. Inform Yourself using Google to enjoy the total Freedom and Customization of Android... If You can't solve Problems Yourself, by communicating and research, don't touch Your Bootloader!
IMPORTANT:
2020+ Xperias are using fastbootd, and equivalent to fastboot which runs in Userspace (Same as Recoveries).
You can access Your Recovery on Your Xperia by holding VolumeDown (-) & the Powerbutton (Your Device needs to be turned off before ofc). Release the Powerbutton after the Display turned on and hold VolumeDown (-) until You see the Recovery Screen. From there, You can enter fastbootd and fastboot. Labled as "Fastboot" for fastbootd and "Bootloader" which is the old fastboot. You can flash Kernels, Recoveries and other stuff from fastboot. Everything else like System Images (GSIs for example), Product Images, System_ext Images and any Userspace stuff has to be flashed from fastbootd. 2019 Xperias are still using fastboot only...
Fastboot and Fastbootd has nothing to do with SONYs Flashmode on Xperias!

Many thanks for your guide. Im just about to receive my phone in 2weeks time.
Is it a good idea to update android to the latest one before unlocking the bootloader and rooting the device or doesn't matter?
Make sure the device is up-to-date before rooting.
Note: the arms race between those rooting their devices and Google/app developers is particularly fierce at the moment. This means that you are likely to face issues hiding your rooted status from apps.
For example there is currently no way to root and still use both Google Pay and the Starling banking app. This is because Google Pay requires you to use Displax's Universal Safety Net Fix Mod to pass Play Integrity, whilst Starling detects any use of Zygisk (by means currently unknown) which UNSF relies on.

Question [SOLVED][ROOT] Zenfone9 bootloop

My Zenfone9 AI2202 (JP) Stopped at bootloader screen.
When I select recovery, it reboots and goes back to "Start" screen.
I used the following as a reference
Rooting Zenfone 9 with Magisk
Guide has been reworked to be more clear and based on comments. [Part One] Backup Data Update phone to latest version [Part Two] Download the Firmware for the Zenfone 9...
forum.xda-developers.com
Steps
- I have implemented the following steps
- Update OTA with Version WW-33.0804.2060.113 (2023/03/31)
- Download Same version of firmware
- dump boot.img using Payload Dumper GUI
- I patched boot.img with Magisk
- Execute the following command.
$fastboot flash boot patched_boot.img
I fell into a bootloop.
It is recognized as a fastboot device by Windows11.
Tried
I flashed boot.img before modifying it with Magisk.
Maybe I had wrong version on my device.
ASUS Flash Tool v2.0.1.0 only recognizes it as State: Fast boot device
I referred to the following
https://www.getdroidtips.com/asus-zenfone-9-ai2202-firmware-flash-file/
It says I can select "apply update from sd card." in Recovery mode,
But when I press the power button in Recovery mode, it reboots and won't let me enter recovery mode.
Question
How do I write the whole firmware?
I wish there was a flash-all.bat in the firmware like in Pixel series...
couldn't start from TWRP
$fastboot oem device-info
Device unlocked: false
The device may not have been successfully unlocked.
But then shouldn't fastboot flash boot boot.img fail?
Can boot.img be written without unlocking?

Yes, I used Asus unlock app tool.
However, seeing that it is not locked, it may be that the unlocking was not successful.

Thank you very much. In the relevant thread, you had the information after exchange about whether "EDL cable" is needed or not.
It is important to read carefully.
I solved the problem by running "flashall_AFT.cmd" with device recognized as fastboot device.
Android 12 is now booted!
I was worried that IMEI would disappear, but I was able to keep IMEI.
My device was purchased in Japan, so it was equipped with Felica, which could also continue to be used.
Thank you very much for your good advice.
