Download fastbooot rom(.tgz), unpack with winrar and flash with Mi flash tool. In Mi flash tool select Flash all and lock option. Phone put in fastboot mode (volume down and power when phone is tured off).

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

Hi After updating .kdz using KDZ updater itreid to do fast boot (CAMERA+POWER)
it is not doing fast boot.. it is doing a normal boot
Nice tutorial for ROM update try it
h*tp://android.modaco.com/content/lg-gt540-optimus-gt540-modaco-com/323450/2-1-instructions-quarx-black-rom-full-insrtuctions-with-clockwork-recovery/
My steps.
Try wiping the phone before performing any rooting or flashing. z4Root Worked right out of the box for me. These were my steps:
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
Wipe phone.Wipe Dalvik.Wipe cache
Install rom.
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

Unlock your bootloader, then Flash the stock recovery through fastboot. You probably won't even loose your data

Stuck in Fastboot

Hi all!
I have tryed to flash Android Q on my Redmi Note 7 (Global) everything seemed to go smooth till i rebooted and the deviced got stuck in fastboot mode, i tryed to flash TWRP, it goes OKAY but if i reboot i cant access recovery anyway.
I also tryed to use "fastboot boot recovery.img", it does send the image but fails to boot into recovery saying "failed to load/authenticate boot image..."
Am i doing something wrong? How can i solve this?
I thought of MiFlash Tool, but there are many version and some seems not to work properly can anyone provide a working link?
(Ofc, my bootloader is unlocked etc)
Thanks a lot
After you flash TWRP you can't access via command, because MIUI will re-write the recovery again once you restart, first flash the TWRP (fastboot flash recovery the-name-of-the-file.img) after that you must reboot to recovery manually by holding together "Volume Up + Power" until you see the MI logo, release "Power" button but keep pressing "Volume Up" until you see the recovery, after you are in TWRP, (mount the internal storage (Data) or if you already copied OrangeFox Recovery Zip to device) then just flash OrangeFox R10_2, it will reboot itself after that to the recovery again and that's all, you will have a custom recovery ready.
Now, if you already tried to flash the ROM and everything went wrong, I guess your device is bricked, now you need a FASTBOOT ROM for your device (if it's complete global = PFGMIXM / because there's global europe too, that's PFGEUXM) and the MiFlashTool, unzip the Fastboot ROM, open the MiFlashTool, load the ROM Folder in the tool while the phone is connected to the PC, and then just flash it, steps with images are in Xiaomi site, here's the link Fasboot Method
ps: the tool have below one option to flash and re-lock the bootloader, it will be selected by default, leave it like that if you want to re-lock it, or change it to clean all to leave it unlock it

Hi dears! Just trying to sum up in case someone end up here just like me: Got stuck on fastboot. What solved was format data partition via orange recovery.

I have tried and I make mistakes. ''waiting for any device''
