yes I did, my bootloader has already been unlocked

Flash factory image manually then, I don't trust in any program except my head
1. Download factory image
2. Download adb and fastboot
3. Extract factory image (all the files) in the adb/fastboot folder
4. Go into bootloader mode and connect it to the pc
5. Open a command window in the adb/fastboot folder
6. Type
Code:
fastboot erase system
fastboot erase userdata
fastboot erase cache
fastboot erase recovery
fastboot erase boot
7. Go to the adb/fastboot folder and select flash-all.bat file, and let it flash
It works absolutely always!!!

updated my n7 3g to 4.2.2 and now when i chose to unlock bootloader (with 4.2.1 chosen) it stops on waiting for adb mode when i write no.If i go to fastboot and write yes pertty much same,nothing changes...I got drivers and debugging on
help
Seems like adb is not working, most likely because of the new 4.2.2 security for adb debugging. I pulled my hair out for 3 hours the other night trying to get it to work. I had to uninstall the drivers, reboot, test, rinse repeat. I was using Wug's toolkit, it details everything pretty good.
Activate developer mode, enable adb, plug in your device, send an adb command (like adb devices). It will send back adb offline. Now look at your phone. You should see a screen about allowing adb from your computer. Allow it. Now once or twice, this prompt did not appear for me. I simply had to unplug and replug the device, then it appeared. Once it is allowed, test it by doing the old adb reboot bootloader and once there fastboot oem unlock and there you go!
Or you can continue with your tool kit at that point, up to you !!
Hi, FatalaS...
I'm not familiar with WugFresh's toolkit... or indeed any other toolkits... I'm more of a fastboot man.
I also generally don't tend to use adb much, except when I'm performing a full backup (via adb pull) to my laptop (which is infrequent, as it seems to take forever - a LOT of stuff to be backed up!).
I use fastboot primarily... for flashing custom recoveries and new kernels/boot.img's.
I do this by copying my chosen recovery.img file (currently TWRP, renamed as recovery.img) or a boot.img file (currently franco's, renamed as boot.img), into the same folder on my laptop, where I keep my fastboot and adb executables.
I shutdown my Nexus 7, and reboot into FASTBOOT/BOOTLOADER mode by pressing and HOLDING the VOL DOWN button, and whilst HOLDING, press the POWER-ON BUTTON.
Having connected my Nexus 7 to my laptop, I then check I have a valid FASTBOOT connection (via a command prompt window, open on the folder I alluded to above), with...
Code:
fastboot devices
This should report a serial number along the lines of something like this...
Code:
015d2424b1xxxxx fastboot
...and then... (and this is directly pertinent to your original question)...
Code:
fastboot oem unlock
...will unlock the bootloader - YOU DON'T NEED ADB FOR THIS - JUST ENSURE YOUR TABLET IS IN FASTBOOT MODE AND RUN THIS COMMAND.
I did this several months ago on my Nexus 7, and once done, it never needs to be repeated... unless you relock the bootloader at some point, with the surprisingly original syntax...
Code:
fastboot oem lock
------------
Having done this (unlocked the bootloader), you can then fastboot flash custom recoveries (like TWRP or CWM) with...
Code:
fastboot flash recovery <your chosen recovery.img>
...or flash CERTAIN (but not all) custom kernels, with...
Code:
fastboot flash boot <your chosen boot.img>
Some kernels consist of more than just a simple boot.img (such as franco's)... some put various files in various parts of /system and thus need to be flashed via your chosen custom recovery, in much the same way custom ROMs are flashed.
-----------
Hope this somewhat lengthy post helps...
Rgrds,
Ged.
You can't unlock 4.2.2 Android with 4.2.1 Toolkit the Android version MUST MATCH.

Listen to this video CAREFULLY + read the Toolkit thread slowly and you will find your solution.

4.4.2 to 4.4.4

Not sure what happened here with this freaking thing. I followed the instructions located here. I grabbed both the 4.4.2 and the 4.4.4 located here.
I applied 4.4.2 to go back to stock and the tablet didn't make it past the Nexus boot logo. So, I rebooted into the bootloader and then flashed 4.4.4 thinking there was an issue.
Same result. Still no boot.
Any ideas? Of course I didn't back squat up because I did this same exact thing on my Nexus5 and it worked flawlessly. So, I figured, why back up anything because it will work the same on this tablet.
No clue what the %&@(&% happened.
I also can't get into Recovery mode either.

How did you flash these update with fastboot?
Yup. Copied all the files in the factory images to "platform-tools". Opened a CMD prompt window and then typed "Flash-all"

Going to re-download the 4.4.2 and re-flash it.... see what happens. But so far, no joy on anything at the moment. Just stuck in a bootloop.

If using windows is the file called flash-all.bat ?
make sure if you are using windows that your CMD window is opened as Admin....
Can you do this again and post the input and output of the process here ?
Thx Josh
Yes Sir, I am.
I've done this:
Proceed with this step if you want to keep your data intact. If you skip this step, your data will be wiped. With your favorite text editor, edit (be careful not to run it by accident instead of editing) flash-all.bat (if you're on Windows) or flash-all.sh (Mac, Linux) and remove "-w" from the fastboot update command. For example, if the line reads fastboot -w update image-razor-jss15j.zip, it should now read fastboot update image-razor-jss15j.zip. The -w option instructs fastboot to wipe data.​Which worked flawlessly on my N5 "upgrade".
I am an Admin user on this machine so the CMD prompt is Admin.
There are no errors either in the CMD prompt window or, the Tablet. Everything appears to transfer over without any issues / errors.

Yes, I have never had good luck with removing
Code:
fastboot -w
at this point with no recovery and not booting your data is lost...
So I would not modify it and see if you can get it to boot...
Thx Josh

I think the folder you extracted the rom must be in C:\ and have no spaces or symbols, e.g. C:\miuirom and not C:\miui rom or C:\miui_rom.

[Claimed] New method of installing Magisk without ROOT on H872

Can someone assure me will this method work on our device(H872) if we unlocked our bootloader and do accordingly what written here? Or it will damage(hardbrick) our device? He said in a comment that this method will only work on H870, H872 & US997 model, which indicating all unlockable G6s.

NFO:
This Method does not need Root or Custom Recovery
You must have a Stock Boot Image Dump and you also have to be able to flash the patched Boot Image via Fastboot Mode
Requirements:
1. ADB and Fastboot on your PC (for example Minimal ADB and Fastboot) [Thread]
2. Stock boot.img of your Device (extract File from Factory Image)
3. Magisk Manager [Thread]
4. Internet connection
5. Bootloader unlocked [Thread]
6. Developer Options > USB Debugging [Thread]
Patching the Stock boot.img:
1. Copy the Stock boot.img to your Phone's internal Storage
2. Install Magisk Manager
3. Launch Magisk Manager App
4. If prompted to install Magisk select "No Thanks"
5. Press Install > Install > Patch Boot Image File and select your Stock boot.img
6. Magisk Manager should begin downloading the Magisk.zip file used for patching
7. Once download is complete Magisk Manager will automatically patch the Boot File
Flashing the patched boot.img:
1. Install Minimal ADB and Fastboot
2. Connect the Phone to the PC via USB Cord
3. Copy the patched_boot.img from your Phone's internal Storage to C:\Program Files (x86)\Minimal ADB and Fastboot\
4. Unlock the Bootloader
5. Enable USB Debugging
6. Open Minimal ADB and Fastboot
7. Boot into Fastboot Mode, type:
Code:
adb reboot bootloader
7. Flash the patched_boot.img
Code:
fastboot devices
fastboot flash boot patched_boot.img
fastboot reboot
8. Open Magisk Manager and verify Root
9. Enjoy

Go ahead and try it
If the H872 had the flash command, then you wouldn't need to go through that bullsh#t, you could just flash TWRP to recovery...

This does not work on H872 period.
I tried just for the hack of it, you will get
writing 'boot'...
FAILED (remote: unknown command)

Hey guy,
My phone was running the rom "UL-ASUS_X00QD-ASUS-AOSP-17.0615.2005.25-1.1.1-user.zip" (downloaded from Asus Web). I tried to install the TWRP ver 3.3.1 unofficial and my phone was stuck on the fastboot mode only.
After a lot of searching on how to fix the issue, I didn't change anything and almost gave up, until I've read this thread.
My Asus Zenfone 8 flip is STUCK in CSC FASTBOOT MODE PLZ HELP!, RAW FIRMWARE ANYONE???
These are what I did to get the phone into the recovery mode:
1. Extract the rom zip file that my phone was running on.
2. Copy the file boot.img to adb folder.
3. On PC, at adb folder enter CMD, connect the phone then type
fastboot -w
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot reboot recovery
4. After that, my phone can be booted into the recovery mode.
Hope you can solve the same problem as me.
Bye bye ...

Hey,
I'm in the same boat, how exactly do you get those images? The stock rom doesn't include the recovery.img
I'm kind of pulling my hair out, I'm now permanently stuck in fastboot
