Sir, Can you give us a step by step guide how you entered Fastboot. We are eagerly waiting for it.

@pvineeth97
Well i dont see why not... Just be aware that most important functions dont work so basically you lose download mode and gain nothing... But for those who want to try... Just remember i will bot be responsible if you brick or anything.
Remember to ibstall driver prior to doing this.
1. Boot into download mode (vol-up + power)
2. Hook up your phone to your pc.
3. Use partitions.py to format you laf partition(i dont kbow the ezact command and cant check it because i cant enter sl mode anymore)
4. Reboot woth vol up again

Root isn't required?
What is the first screen you saw after rebooting it with vol up again? What's the exact key combination and for how long we should hold it?
How did you use "partitions.py"? Something like this? "python partitions.py"?
What's the software version of your phone when you did this?
We here on XDA will treat you as a king if this works!

First. Im on 6.0 so no root.
2nd. Its the same as booting into download mode. Axtually yoy delete download mode usong this method.
3rd. I would like to join the club who treats the one makibg this useful as a king. Because FLASHING DOES NOT WORK!!!!

Also. Basically you get a acreen telling you its listening for fastboot commands

G3 bricked and fastboot commands not working! HELP

My G3 had TWRP + CM and I want to flash its stock rom...
For some reason, Download Mode wasn't starting and every time I ended up in fastboot (flashing laf and aboot didn't help either).
So, I decided to erase everything and again clean flash them one by one using fastboot.
Now, here is the problem:
No fastboot command is working! It just hangs at executing the command....
For example, when running 'fastboot erase recovery', it shows
Code:
erasing 'recovery'...
and nothing happens! No response, nothing. The same for flashing, rebooting, ... I have to halt (ctrl+C) every time I enter a command.
The only thing that works is
Code:
fastboot devices
which shows my device with a question mark.
Had the same issue yesterday (after using Fulimics 6.5), my root seemed to be gona, I was stuck in recovery, no backup (what an idiot I am...), can't flash anaything, sideload not working...
I had to come back on stock with the KDZ method : http://forum.xda-developers.com/showthread.php?t=2785089
But you are saying your download mode isn't working ? That's really strange, Volume Up and then insering USB, mainting volume UP until the phone goes into download mode ?

Yes, this all started because download mode wasn't coming up. I press volume up, insert USB and then it goes straight to fastboot:
Code:
[470] Fastboot mode started
[560] - reset -
[560] - partcharge -
[660] fastboot: processing commands
(numbers are different each time)
I think I saw the download mode icon for a second before this but not sure.

LG G7 - Fastboot bootloop [SOLVED]

After trying to flash Pie my G7 stuck in fastboot mode. Download mode is unavailable so I not can reset the stock ROM.
After it reboots it boots into only to fastboot mode and is stuck in a loop now.
An even bigger problem is that now the bootloader is locked and the unlock.bin file can not unlock the bootloader.
ADB mode is not working!
DOWNLOAD mode is not working!
SYSTEM mod does not work!
There is only FASTBOOT mode that is in the loop
Does anyone have any suggestions?

My G710EM has a problem with my lockback BL. I can't boot the system and it will prompt "Your device has failed a routine safety check and will not boot. This may be a temporary problem. If this message occurs repeatedly, visit this link on Another device and refer to the red case:g.co/ABH Your device will power off automatically after a while.” With LGup brush kdz brush does not go in, fastboot “fastboot flash unlock unlock.bin” prompt is invalid

I had the very same problem as OP. I tried to install pie with LGUP (G710EM20b_00_OPEN_EU_OP_0508.kdz) but ended in fastboot loop.
After whole night of trying different things (being a noob means less sleep) I managed to run the phone in download mode. Starting from there I was able to install my previous rom. Both failed update and rescue operations were done on Win 10.
What I tried and didn't work:
- Fastboot --set-active=a

- Unlocking with unlock.bin. Didn't save the msg but saw it somewhere in another thread. I needed to install/point drivers first because the device was not recognized in Win.
- Solutions for G6 for going into download mode. The download mode icon was displayed for a second and then going to fastboot again.
- LG Flash Tool 2014 - I just followed a guide for older phones but it didn't work. Didn't try again.
What did work:
1. I found this post on reddit (remove spaces or PM me, I'm not allowed to post links):

Quoting the post
At first, you'll need a working fastboot environment, you'll find out how to set it up on your own. Then you'll need the laf.img, I can upload mine if you want or I could help you extracting one out of a kdz file. Put the laf.img in the same folder like your fastboot.exe, then hold shift and right click, then click on "open command panel here" or however it's called in English. Type "fastboot flash laf laf.img" (Edit: It would probably better to use "fastboot boot laf.img" instead because of the bootloader lock). If that works, you at least have a working download mode.

2. I used LG_Firmware_Extract_v1.2.6.1 and extracted dz file from aforementioned pie file. The I extracted two laf files for the kz file. In my case they were: laf.img_180534 and laf.img_81990.
3. I took one of these files (sry, don't remember which one, but they have the same size - didn't check if they're the same) renamed it to laf.img and put a folder where fastboot.exe is.
4. I did
Code:
fastboot boot laf.img
and voila: the phone was in download mode!
5. After that LGUP the previous rom and the phone is working again. Here I needed few tries. At first the were some problems, then I tried different combinations (1.14, 1.15, w/ and w/o uppercut). I think LGUP 1.15 (1.14 with patch) did the work. I was able to "refurbish" the phone.
Hope it's useful for others. If anyone could prepare a guide from this description or/and tell why it worked - please feel free to do so.
I think I will wait some time before trying pie again

I recall I also had some error msg, it could've been the same. Now I don't remember what I exactly did next as most my actions were more or less random. Either I tried the same command but with other laf.img file (from the rom I used before), or I tried to restart the phone into download mode (vol- and power together and then vol+ after screen goes black) or tried the same file again.
Hope it helps.

Check if the phone is recognized in LG Bridge. If so, then choose update error recovery from software update tab. Again, I don't remember if it worked immediately or did I need to reinstall drivers and/or choose a proper driver in device manager (generic ADB vs LG...) and/or restart the phone.

Based on other threads, e.g. https://forum.xda-developers.com/v20/how-to/restore-v20-to-100-stock-bricked-devices-t3524903 and https://www.reddit.com/r/lgg6/comments/axd17d/lg_g6_eu_glh870_bricked_after_update_your_device/
try:
install the LG Bridge updater software on a computer, go to updates, click the "correct update errors" button. Then plug in your turned-off phone while holding down the volume up button. It should switch to download mode and reinstall all software from the PC. Yes, this will erase all data but it should unbrick your phone (unless the hardware's broken I guess)

Bootloop to Bootloader

I am stuck. This is my first phone with an A/B Partition and I have managed to erase everything except my bootloader. I can use fastboot and flash but i can not get this thing to reboot into system or TWRP. Can anyone help me here?
I have tried the guide using flashall_aft cmd and I cant seem to get a flashall to work either.
Keep phone in fastboot mode..
Extract boot.img from the last firmware you are in and flash it using fastboot command...and reboot bootloader..now AFT will work.
Since you are in TWRP, AFT will not work cus you are in modified boot image. Do not wipe anything now...just do above...AFT will work.
This phone AB partition scheme is dicey and little mistake phone wont boot. Lucky you, still fastboot is availble
I am only able to access bootloader with active slot as b. Tryed using commands to switch to slot a but I am having no luck. I cant flash the system or recovery, only the boot.img and a reboot just takes me back to the bootloader.

Is the flashall_aft.cmd file in that directory? I.e can you see it ?
Get raw firmware zip, extract and run flashall in raw firmware folder. Firmware comes with script. It will restore Android file system. Boot to system and update fw and you're back to square one.

If you can't boot into bootloader by any means you may want to look into intensively technical unbrick methods. There are guides in this forum. If you have tampered to the point where its practicality is outweighed, you made a mistake unfortunately RIP your device.

What you are trying to do? Just switch from Chinese to Global? or your device is bricked now?
What did happen after that you flashed the Chinese recovery ROM?
What modes do you have available?
Did you unlock bootloader previously?

Fastboot flashing commands won't work if you have bootloader locked.
Did you unlock bootloader previously and probably get locked again?
Did you enable all the proper options on Developer section, i.e. USB debugging and check if device is recogniced on adb commands?
What do you get with "fastboot getvar all"?

And you said you enabled USB debuging?!? you didn't. First enable it under development tools.
MAKE SURE YOUR USING RIGHT ADB/FASTBOOT TOOLS AND DRIVERS.
After 'adb reboot bootloader' use 'fastboot devices'. You can change usb cable and if you still get errors try using usb hub.
If all above fails than try it on WIN7 PC.

I think you are not properly booted to the proper state while you're trying certain commands. Just to be clear; adb works while your device is power on and fastboot commands will work only while your device is in fastboot mode not while on adb mode. A way to be sure that you are doing properly is enabling USB debugging first but while connected device with PC, a prompt will appear from device screen and then tap on "always allow", then you have to type "adb devices" and follow step by step, if device is recognized you can go to the next step with "adb reboot bootloader" then in fastboot you have to see the bunny otherwise is not properly in fastboot mode, then you can follow with "fastboot devices" and so on, keep in mind that any command will work until device is properly recognized.

A way to be sure that you are doing properly is enabling USB debugging first but while connected device with PC, a prompt will appear from device screen and then tap on "always allow", then you have to type "adb devices" and follow step by step, if device is recognized you can go to the next step with "adb reboot bootloader" then in fastboot you have to see the bunny otherwise is not properly in fastboot mode, then you can follow with "fastboot devices" and so on, keep in mind that any command will work until device is properly recognized.

thanks bro
yesterday i used xiaomitool v2 as it reboot automatically device in fastboot mode but as i said after in fastboot mode it doesn't boot in adb mode.
and what is proper method to open fastboot mode i m doing it by holding power and volume down button.
drnightshadow said:
And you said you enabled USB debuging?!? you didn't. First enable it under development tools.
MAKE SURE YOUR USING RIGHT ADB/FASTBOOT TOOLS AND DRIVERS.
After 'adb reboot bootloader' use 'fastboot devices'. You can change usb cable and if you still get errors try using usb hub.
If all above fails than try it on WIN7 PC.

Just trying to determine what your words exactly mean when you say "after in fastboot mode it doesn't boot in adb mode." ... without entering in more technical insights adb works when device is on, no sense to boot to fastboot to try to boot to adb after that (?)
If you can boot to fastboot what you have to try firstly is unlock bootloader or be sure that is already unlocked using
Code:
fastboot oem device-info
if your device is or get unlocked then you can try to flash or just boot to a custom recovery but if you can't determine until now if your device is really unlocked then you couldn't go further.
The hardware method to enter to fastboot is from a device off; pressing both pwr and vol down buttons but if the bunny is not displayed probably you didn't really get fastboot mode.

Do yo use WIN10? Find PC with Win7... and install adb/fastboot app and drivers. Than try..
Is your system working now?
Just unlock your bootloader and install OrangeFox recovery than you can flash whatever you need.
Problem solved.

TWRP can't bypass encryption, when you have no access to read data (0mb) then you have to format it, to avoid that is always recommended use OrangeFox, just for future reference, if you understand that you can flash OrangeFox through TWRP for better experience.
Also you can use this tool to help you to automate some stuff https://github.com/Szaki/XiaomiADBFastbootTools

Power off your phone completely.
Hold Volume Down and Power key together and release the buttons once you see the Android One logo on your phone screen.
Now your phone will be in fastboot mode.
Install ADB and Fastboot drivers on your computer and open CMD and connect your phone in fastboot mode.
Type command fastboot erase userdata and the phone shall reset.
if the above command does not works, type put phone in fastboot mode again and type command in CMD as follows
fastboot reboot-recovery or fastboot reboot recovery.
Please let me know if this helps.

I do understand your concern. I would first recommend you to unlock bootloader and then use magisk to patch the boot.img.
I cannot do bootloader unlocks for Qualcomm phones.

Is that an open offer? Cuz I've got a brick that used to be a Nokia G300, and a computer I don't much value, so I'll take the chance.
