Tutorial
To do that follow the steps bellow:
KDZ Updater method
1. Boot in fastboot mode and execute the commands bellow:
- "fastboot -w"
- "fastboot erase system"
- "fastboot erase boot"
2. Reboot from fastboot directly to download mode (Power + Volume Down key)
3. Connect your phone to your PC and open KDZ Updater
4. Select any fastboot ROM
NOTE: YOU CAN NOT FLASH A NORMAL ROM!!! YOU MUST USE A FASTBOOT ROM!!!
5. Flash your rom in "Emergency Mode"
6. When finished the phone will reboot automatically
Recovery method using my brother's recovery file
1. Boot into Recovery mode
2. Wipe your user data (Factory reset)
3. Choose the update.zip file from your SD Card. You can download it here
4. After the update is done, reboot the phone
The ROM is V20A, so it supports Portuguese language.

Hi,
I have the same problem here.
I have upgraded to SwiftDroid 2.3.7 using fastboot command, because there is no boot logo and no recovery in my gt540, after updated with clockwork recovery rom.kdz. But the rom worked just fine.
I had problem the day after. My GT540 won't boot, it only vibrated and when I plug it to PC, Pc recognized fastboot mode. So I downgraded to frenchV20C.kdz without using fastboot -w fastboot erase boot and else.
Now, my gt540 is bricked, it only vibrates when I hold power button, and nothing happen. Can't boot into fastboot mode now.
Any help would be appreciated.

[HELP]Can't enter recovery mode

Ok, I've bricked my ZF 5 and have gone through many tuts to unbrick it but unfortunately I can't get into recovery mode. I can enter the droidboot mode by pressing Vol down + power button but when I click on Recovery there, it gets stuck at the boot screen mode(the one we see before entering into droidboot mode) and stays there forever. The adb shell does detect this and I did try to flash a recovery img through it but still no use. Can anyone get me out of this please?

download firmware from asus site, unzip them and you will see some folders and: recovery.img droidboot.img and boot.img
so, download and 1.0.32 and put recovery.img to folder with adb files.
boot Zf5 to fastboot/droidboot plug in computer ( you need asus drivers ) open cmd window in adb folder (SHIFT+ RIGHT CLICK) and then write : fastboot flash recovery recovery.img
press enter and wait, now try boot to recovery
you can try flash droidboot.img and boot.img too

Do one thing when you get into fastboot and tap on recovery an asus logo is seen.
Then kindly hold your power button and then your device will switch-on to twrp easily.
The actual problem is because of your device unable to get into twrp automatically so herein the above method you are manually getting into device.

I seems that the right command is "fastboot flash recovery twrp.img"
Unless you wanna install the recovery onto the kernel partition.

@OP: The correct command to flash the recovery is
fastboot flash recovery twrp.img
Please correct it in your post.

it does't work

Because the instruction in first post is incorrect, after you flashed recovery you also need to use this command: "fastboot boot recovery_image_name.img"
This is needed only to boot into TWRP for first time, if you intend on flashing custom ROM's then Format DATA,reboot to recovery again and you can use it normal.

Can't boot to twrp

Ok so i tried a lot of different things but my phone just doesn't want to boot to twrp. I flashed twrp but the phone always boots up erecovery.
What am i doing wrong?

Did you try the simplest command? Connect the phone to PC and open CMD or Windows PowerShell then run : adb reboot recovery
Also you can use Huawei Multi Tool 8 to boot into Recovery (Root tab -> Restart to Recovery).

i figured out what the problem was... I was flashing a zip file with a batch file in it via fastboot XD...

Hi,
I installed this recovery. But evry time I boot into recovery, it said enter password. Then I installed DM verity disabler. after that installed this recovery zip file. Now seems working.
But, when I checked the developer options, it isn't showing device is unlocked. It says "this device is locked", and it wants me to bind account to unlock.
I checked by fastboot, and it says device unlocked = true.
Why developer options shows device is locked?
Installed rom is global stable 10.0.5.0
What must I do to developer options unlock status show true(locked).
thanks...

cannot mount storage, please help
