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.

Ok so I flash the ROM using KDZ Updater = All well and good.
Now I follow your commands to enter this "fastboot business", I get the LG logo come up then it goes to a black screen... So I assumed it was in fastboot?? (not sure what fastboot is lol)
Then I got to windows command prompt I assume u mean? and type the command in pointing it to the android SDK tools folder?
Then I enter the command and it just stays on <Waiting for device> and thats as far as I get? hmm...
ALSO THE PHONE WAS PURCHASED FROM CARPHONE WAREHOUSE WHICH NO MATTER WHAT METHOD I TRY TO ROOT THE PHONE IT DOESNT HAVE IT! Dunno why??
Hi! if i already updated with Baltic V20D Official can i reflash with that one so that i can get Fastboot? ;o

Install z4Root
Perm Root
Powercycled
Downloaded SuperUser
Downloaded Terminal Emulator
Downloaded Rom Manager
Open SuperUser. ALLOW
Open Terminal Emulato. type SU. ALLOW
Open Rom Manager.
Flash ClockWork Recovery
Boot into Clockwork

Reboot.
Enjoy.
Please i need help c: i run 2.2.1 openswift and if i flash clockwork is my rom gone then?
i really don't want to flash with adb again The brick chance is to big :c
The answer is No, Because the recovery will be in different partition. so u will not loose your ROM if u flash with new recovery.img
Guys,how do I go from 2.2.1 to 2.1 I tried with kdz but I showed Arm 11 crash!!!!
Arm 11 crash
Last week i also got this error.. but don't worry
follow this u should be able to come out from this issue
1. Remove battery,SIM,Memory card from your phone
2. Connect you phone with your PC using USB cable
3. When its booting press Volume down and Power button until it shows download mode in the phone screen
4. Remove your USB cable from PC
5. Insert the battery
6. Now try to flash your phone using KDZ software update (use the ROM with fastboot)
if u don't hv ROM with fastboot download it from here http://www.mediafire.com/?4r5n1cj5v49151p
Always it is better to,
1. Unroot your phone before flashing with KDZ software ( i don't know why, but i got Arm 11 crash when i tried to flash with out unrooting)
2. Wait while updating if it stuck at call_fun upgrade or Change to Dload Mode
hope it helps

Disable update CM recovery option in developer options... Then flash custom recovery.... it will work.
once flashing twrp recovery, you will need to use
Code:
fastboot -i 0x1ebf reboot
command.
remove battery after install recovery before restarting phone
then insert battery and start in custom recovery
install Custom Recovery
1) enable developer options
2)enable advance reboot and usb debugging
3)disable Update CM recovery option
4)reboot to bootloader and flash recovery
" fastboot -i 0x1ebf flash recovery recovery_twrpyulolli.img "
5) directly disconnect phone (phone displaying FASTBOOT MODE)
6) remove battery and start phone in recovery mode using volume UP+DOWN and power key
7) And YOUR are IN TWRP RECOVERY ......
THIS method work for me perfectly .....i m also having same problem of flashing custom recovery and again showing CM RECOVERY
:laugh::laugh:
Thank You...!
Which is best for yureka cwm or twrp recovery
I'm facing the same problem but this trick didn't work for me.

Unable to flash TWRP using fast boot mode

Hello friends
Today I tried flashing the TWRP using fast boot mode but got an error -
"fastboot' is not recognized as an internal or external command, operable program or batch file. "
Any idea why this could be happening? I have reflashed the MIUI Rom using fastboot rom. The boot loader is unlocked.
Help will be appreciated.
Regards.
Friendly Bump
Need help quickly.

Boot from SD card. EMMC memory is dead

I have the wt86047(HM2014813,HM2XTDPro) and I have dead emmc on my phone. The internal /data /system and /cache partitions are unmountable. So I decided that I try to boot from sdcard.
I have used this tutorial Dual boot to partition my sdcard and modify the recovery and the rom(Lineage 14.1) to look for the system, data and cache partitions on sdcard.
But when I try to boot up the phone is stuck at the MI logo and I see my device in fastboot. To be able to boot to my device I need in fastboot to execute fastboot boot modifiedboot.img. This is not too much convenient as I need pc to turn my phone on. I also can only boot recovery and not to get to the recovery mode. I can however flash the image to the /recovery partition. I suspect that my /boot partition is also corrupted. I tried to manualy flash boot also with no succes. Any ideas how to boot the phone without need to use fastboot?
I have the exact same issue with the same phone.
You have modified only the fstab file ?

In boot.img yes(fstab.qcom), in TWRP the etc/recovery.fstab and in the updater script any mention of /system and /data.
The phone boots with the fastboot boot, but it is quite slow as I have quite cheap sd card in it. I would buy a better one If I would be able to boot the phone without computer.
EDIT: Camera is also not working for some reason
Try folding the fastboot ROM.
Same thing happened to me. I tried and flashed the fastboot image. It worked. This happened to me a long time ago. Don't worry about bootloader if you can see the fastboot screen with the mi man on your phone .

This won't help. This is the hardware issue. The storage chip on the motherboard is dead. You can not write anything to it. It is possible to replace that chip but it is a quite difficult operation.
