[Fixed+How to fix] G2 weird Fastboot mode - G2 Q&A, Help & Troubleshooting

My phone is bricked, it boots on fastboot mode, when i plug it to pc it shows this lines:
fastboot mode started
-reset-
-portcharge-
-reset-
-portcharge-
fasboot: processing commands
when i try to go into download mode it works for few seconds then go back to fastboot with the same lines
when i go to recovery and try to delete everything it works then boots into this fastboot mode again and pc won't recognize it help me please

UPDATE : I installed Qualcomm drivers and now device is recognized as android bootloader interface

UPDATE: I got out of fastboot somehow, i got into download mode successfully and then i flashed a stock rom kdz via LG FlashTool2014 but it seems that it's not the right one because it's now stuck in lg logo bootloop, my phone is a D802 International but i don't know which rom is the right one for this model, if someone knows something please say it it'll be really helpful thank you ^^

Where are you from?

Algeria, but the phone is from europe (i don't know exactly where) and i don't have the box anymore :/
EDIT: I tried 2 stock roms for now
-Europe OPEN D80220B_00.kdz
-Europe OPEN D80220D_00.kdz
Both didn't work, and the second one i couldn't get into factory reset (holding power and vol -)

UP: Everything is fixed, here are the steps I followed in order to get my phone back to life:
---Do this steps only if you have those white lines after installing wrong auto-rec version on the LG G2 D802---
---This method worked for me,it may not work with you, use it at your own risk---
-Your phone should not be recognized by pc, so install adb and qualcomm drivers, then in device manager it should appear as "bootloader interface" or "adb interface ..."
-Download right kdz rom for ur phone
-Extract the laf.bin aboot.bin boot.bin recovery.bin rpm.bin sbl1.bin tz.bin and dbi.bin
-Go to adb folder and past these .bin files there then rename them into .img (aboot.bin-->aboot.img)
-Open a cmd and write fastboot, to be sure that ur phone is recognized do a -fastboot reboot- if phone reboots then it's all good
-Now you have to erase the laf.img, aboot.img, boot.img etc.... from the phone, to do that, in the command prompt write: -fastboot erase laf.img- and do that for all the other .img
-After that you have to flash those .img eg: -fastboot flash laf laf.img- ( if it says cannot be loaded or cannot be reached, write the directory into the img file eg: -fastboot flash laf C:\adb\laf.img- then it should be fine)
-When you finish flashing all the img files, do a fastboot reboot
-Then shut off your phone (hold power button for like 30seconds, lg logo should flash for a second then the phone will be off)
-Now you can go into download mode (hold Vol-Up button and plug in usb)
-All there is left is flashing stock rom with LG FlashTool2014 ^^

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.

Device manager shows QUSB_BULK but no tool will see the phone. Any ideas guys.

You can try this tool:

Hi , I did try that. The port manager in the app does not show anything. It as if the phone is not connected. Even though it is listed in windows device manager as QUSB_BULK

Hi,
I waited till the battery discharged. Went into EDL mode. They only success I had is with axon7tool.exe
Miflash will not detect the phone. As seen believe I can read and write with axon7tool.exe
Is there any recovery I can put back on the phone that will run? The bootloader is unlocked. Thanks

Your command with option "-r" (for read) only backuped the existing recovery to your PC.
There was no effect on the phone. It read your phone recovery and downloaded (=backuped) to your PC (probably with name recovery-backup.bin).
Since your booloader is unlocked, you can write official but unsigned TWRP recovery to the phone. This official but unsigned TWRP recovery
will run correctly (since bootloader is unlocked). So you need to 1) download latest official TWRP recovery, then 2) write it to the phone.
1)
On your PC:
Go to https://eu.dl.twrp.me/ailsa_ii/
Download the recovery twrp-3.3.1-0-ailsa_ii.img (14 897 152 bytes, md5 0d57b791c6b7c7d979ea70b0951c519d) with the link:
https://eu.dl.twrp.me/ailsa_ii/twrp-3.3.1-0-ailsa_ii.img.html
Copy the file to the directory containing your axon7tool.exe ("H:\TRWP AXON 7").
Then copy twrp-3.3.1-0-ailsa_ii.img to recovery.bin (command: "copy twrp-3.3.1-0-ailsa_ii.img recovery.bin")
(this means you have a new recovery.bin file which is exactly the same as twrp-3.3.1-0-ailsa_ii.img file).
Explanation: this to prepare to write TWRP recovery to the phone, the axon7tool.exe syntax "-w recovery" requires a file named recovery.bin
which has the content of the recovery you want to put (in your case, latest official TWRP recovery twrp-3.3.1-0-ailsa_ii.img).
On your PC, go to H:\TRWP AXON 7 directory:
H:\TRWP AXON 7>
type "dir" command, you should have files: axon7tool.exe, recovery.bin (identical to twrp-3.3.1-0-ailsa_ii.img), twrp-3.3.1-0-ailsa_ii.img and other files.
2)
Put you phone in EDL mode as you did before.
On your PC, type the following command to write TWRP recovery to the phone:
axon7tool -w recovery
(Explanation: the above command will write (-w) the recovery to the phone using the file named recovery.bin (= twrp_rec_tenfar.img) found in your PC.
You can then boot to recovery, using menu in bootloader at start (use Vol-Up, Vol-Down for selection, Power to Confirm selection).
Other way: if phone is power off: Vol-Up + Power to get into TWRP recovery.
Afterwards, with TWRP you have total control on the phone, custom ROM etc...

Phone stuck in Sony boot logo (not even charging), please help!

Hi Friends,
I have decided to create a new post, since I researched and it seems that my issue is not covered exactly by any previous thread.
I have Sony F5321, used years with Stock ROM. While playing a game, it turned off randomly, but when I play the same game while charging with USB cable (with AC charger or connected to a laptop), the phone was working fine. I have unlocked the bootloader and flashed LineageOS 16 (Android 9) in case a battery issue was solved better with LineageOS than with stock ROM. After some weeks with same (supposedly) battery issue, I decided to go back to Stock ROM. I have flashed OK with Flashtool (no errors), but phone is now stuck in Sony boot logo.
The status is:
1) Boot into Stock Rom: doesn’t work
2) Boot into recovery: doesn’t work
3) Force shut down (3 vibrations): works
4) Force reboot (1 vibration): doesn’t work, it stops at Sony boot logo
5) Charging while powered off: doesn’t work (no battery logo appears, red light)
6) Flashtool into flashmode: doesn’t work (it’s not detected)
7) Flashtool into fastboot mode: works, but I cannot do anything with that.
Please, your help, how can I get the phone works again? Preferably with Stock ROM, or any other stable ROM, but working! Thanks!
Nobody will help?

Sounds like hardware failure to me, happened to me before... However, if you can get into fastboot, just go ahead and flash back to a custom kernel and recovery, and see if you can boot to recovery. That will tell you if it's not a hardware issue, then you can figure out how to get back to stock...

I tried a lot of things now. To confirm, I tried to use Flashtool in fastboot mode, but not sure where I get a custom kernel file to use with Fastboot menu option "select kernel to flash" but I have downloaded again lineage-16.0-20200511-UNOFFICIAL-kugo.zip file, should I take "boot.img" from unzipped directory? and how to flash the twrp-3.3.1-0-kugo.img file with Flashtool? which is the option to flash recovery using Flashtool in fastboot mode?

Don't need Flashtool for fastboot. If you have the drivers installed, use your computer, and connect with the power off, holding the volume up button, and let go of the button when you see the blue led light, (if you don't get a blue led light, could be further evidence of a hardware issue). Now you're in fastboot mode.
Open a command prompt, and type "fastboot". If fastboot / adb is installed on your computer, and is set in the path, you will get a fastboot reply, if not, you will get, "fastboot is not recognized as a program or command...", or something like that. In that case, you need to either install fastboot, (look it up - it takes about 30 seconds), or, in the case of Linux or if you have the fastboot / adb files on your computer, but it's not in the Windows path, just change directory in your terminal to the directory where the files are, then try the command again.
Once you have fastboot working, just copy whatever you want to flash to the same directory you're in, and the commands are:
Kernel -
Code:
fastboot flash boot [name of file].img
Recovery -
Code:
fastboot flash recovery [name of file].img
ROM -
Code:
fastboot flash system [name of file].img
OEM (needed for recent AOSP -based roms) -
Code:
fastboot flash oem [name of file].img
Curious - how did you flash Lineage last time?

If I remember correctly, I have flashed the LineageOS (and also stock ROM downloaded by XperiFirm) with Flashtool in "flashmode", but then when I got the logo bootloop, it didnt work anymore. Only fastboot works. Not even booting in recovery mode seems to work.
I have already tried with fastboot in windows 10 cmd prompt (now called PowerShell).
fastboot flash boot boot.img --> works OK
fastboot flash recovery twrp-3.3.1-0-kugo.img --> works OK
fastboot flash system [system file].img --> there's no other IMG file inside LineageOS zip file besides boot.img, if you could provide another custom ROM zip file which includes both boot.img and system.img, please let me know
in addition. after flashing recovery OK, I tried "fastboot boot recovery" and the phone boots into bootloop again.
after shutting it off, there's no way to get into recovery mode. Only sony logo and red light (or no light)

So you tried to hold power and volume down to get into recovery? Also, if the only file in the LOS zip is a boot img, then the zip is incomplete. Try one of the Omni roms from the roms thread here. I've used them for N, O, and P, and they all work fine. There's a link to the Sony OEM files in the first post...

Yes, I tried vol+down while power on, and it stuck in sony logo white screen. Also tried from fastboot mode with "fastboot boot recovery" and "fastboot boot twrp.img" and it says "rebooting" but it only disables fastboot mode (windows' typical unplug drive sound), but phone get stuck with blue light.
its really strange. Is it possible that the phone has a battery HW issue that avoids it to charge (sometimes the empty battery big icon black screen appears), and that issue avoids recovery or reboot process?

Maybe specific to battery, but any issue with the main board is going to caused general wackiness... Could be what's happening. Maybe it would be worth it to try a new battery. Have you already tried different cables?

yes, I have 2 USB 3.0 cables. Both works perfectly with my other phone Moto G6 plus, in fast charge mode. it I can flash anything in fastboot mode, but cannot reboot into recovery, do you have other option to try? I downloaded and flashed the Sony OEM file (8.1/9/10) and flashed with fastboot normally. Then I have downloaded the Omni WEEKLY zip file, but in the Omni XDA thread, it says that the zip file must be flashed from Recovery (copied into the SD card), but I cannot access Recovery. I really want to revive this phone.

Thanks for the link! I have downloaded and flashed all the IMG files inside with fastboot, everything OK. But the phone is still not rebooting to system nor to recovery mode. same behaviour. Stuck in sony logo.

!!Resolved!! full brick not without the possibility of entering eRecobery or wtrp

Hi I was looking for a solution to fix my p10 lite that when restarting in twrp or eRecobery it threw black screen and restarted and remained in bootlogo
My device is the Was-Lx3, which was more difficult to give alone since I could not find a system and I could find one for my model and thanks to the fastboot commands it was restored from the factory
Link of the rom that I downloaded and it worked
https://mega.nz/file/DFhziCjI#c1vkVdcvKj3mR_wBb3Kbe_BAA5HUYaCtJVFLkUt9rLk
The steps is:
1 download the rom and unzip the rom
2 leave the device in fastboot mode and run Adb FASTBOOT
3 Flash the .img files I will leave the commands below
fastboot flash boot (drag the file and enter)
fastboot flash cust (same drag and enter)
fastboot flash recovery
fastboot flash system
fastboot flash userdata
ending with the flashing without disconnecting the phone Press buttons button power plus Vol + for 10s and you can enter eRecobery and download the last system you have and ready it will start normal
Even if you have the device without battery, it still works without battery, just do not disconnect the phone and doing all these steps and once the device has been restored, it will start to charge normally. I would like you to give the thank you button if it works if you do not comment below
