Greetings, I tried flashing my LG H440F to its original state via LG Flash Tool.
At the time being it was stuck on 1% and after several errors I desisted and tried another KDZ to flash with same result (stuck at 1%)
Now the phone is stuck in "fastboot", I can't boot it to Download mode neither do a Hard Reset as it does nothing.
Adb does not recognize the device and fastboot always throws a FAILED (remote: unknown command) when trying to do anything.
Did I just entirely brick my phone? If so, how to unbrick it?
Best regards.
Bump
Second Bump! I found out about flashing with Qualcomm drivers directly to the mobo of the phone? Any ideas?

Black screen, boot error, demi god
You may flash your device using "LG Flash tool 2014" with a firmware for your device.
Search on xda for "LG Flash Tool 2014" and you'll get all the resources you need.
If this does not help, follow the tut posted on the following thread by me.

Hi,
I need the LGAS323 firmware kdz file(which i have not found). I've been trying with the MS323 kdz through the LG flash tool but it doesn't work(error).
So this is what happened:
I tried to install CWM recovery after unlocking boot and installing fastboot. So after all that I put the command to start transfering the cwm file and the phone got bricked. Now it doesn't even show up the LG logo. It just power up the screen which people call "purple screen" or black... It vibrates one time whenever I connect it to the PC or push the power button.
This is what I've tried:
I have tried all methods I have found on forums and YouTube. I tried with Linux on the terminal fixing the aboot.img and also on PC with the LG FLASH TOOL and other apps but nothing works. Folks help me with this please. I think the only thing that would fix it is using Jtag or something like that you know the boxes(riff, octocplus...). But without the exact firmware it wouldnt work anyway.
Any expert here?
Thanks.
The phone wont go into download mode! BTW.
I tried to flash my H901 but failed.
I cannot recover it in any way.
When it turns on it loops on the LG logo and a message: boot verification fail!
On Hard Reset it keeps looping on the same screen
On LG Bridge there is a message: Cannot check internal storage on your phone
On LG Flash Tool with H90120e_00_0316.kdz: error connecting to server
On LG UP with TotbypassFRPlgh901.tot: Antirollback version is smaller than device version
On fastboot flashing stock boot.img: writing 'boot'... FAILED (remote: unknown command)
I don't know what else to do, please help!!!!
lg bridge cannot check the internal storage on your phone
It sounds like my H901. You may have inadvertently did what I did on purpose and that was to re-lock the bootloader. After the fact I read that one should NEVER re-lock the bootloader or else they'll end up where we're at. There is nothing to be done at this point, no fast boot, no LG UP, no LG Bridge, nothing.
Found the cure!!!

Hey! I found this link with the real stock firmware for Marshmallow. I installed it with LG UP and it got past the 9% and installed fully and now my H901 is up and running again. http://forum.xda-developers.com/tmobile-lg-v10/general/stock-h90120j000712-kdz-t3436249
I then found this one http://forum.xda-developers.com/tmobile-lg-v10/general/root-android-6-0-h901-t3382819 and updated with LG UP and now I'm rooted; the phone is no longer bricked and everything is working great. Titanium Backup is back!!!
You guys are trying to downgrade v20j perhaps which will give error or brick your H901. Don't do it, make sure you are flashing KDZ of v20j only. And btw, re-locking bootloader does not brick your device. I relocked 3 different H901s while on V20j.
Hi,
I'm new here, so please excuse me if I am posting in the wrong category.
So I tried to root my Doogee F7 (not the pro version) using fastboot and TWRP, and it resulted in a sort of bootloop where it says:
Code:
Orange State
Your device has been unlocked and can't be trusted
Your device will boot in 5 seconds
And then it restarts and gives the same message again. This loop has been going on for some time and I can't stop it because the phone has a non-removable battery and I have tried every possible combination of buttons (i.e. Power + Volume Down + Volume Up).
The process I used in my attempt to root was as following:
1. I used
Code:
adb reboot bootloader
to go into fastboot. (I already set up everything like USB debugging and OEM unlocking in the developer options)
2. I then used
Code:
fastboot oem unlock
and pressed Volume Up to unlock the bootloader. All was successful.
3. I then tried to flash TWRP to recovery and I believe this is where everything went wrong. I flashed it using
Code:
fastboot flash recovery recovery.img
and it was successful, according to the command prompt:
Code:
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot flash recovery "C:\Users\momen\Downloads\recovery (1).img"
target reported max download size of 134217728 bytes
sending 'recovery' (12832 KB)...
OKAY [ 0.562s]
writing 'recovery'...
OKAY [ 0.213s]
finished. total time: 0.779s
4. After it finished I used
Code:
fastboot reboot
to reboot the phone and that's when it got stuck.
At the moment I am just letting my battery run out, as I have no other way of turning off the phone, and neither adb nor fastboot is working.
I don't really know if my device was even supported, but I followed the instructions on various websites stating that I should first unlock my bootloader, then flash TWRP, then flash superSU onto it, and my phone would be rooted. I used the latest TWRP image, and I think that was where I went wrong. Is there anything I can do to get my phone to work again?
Hey! i´m sorry for your phone, can you tell me any updates, is it fixed now? what happened? i am about to do the same process to root my Doogee F7 and i´m very worried that my phone gets bricked, so please, i need your recommendations.
I hope everything is alright with your phone.

Ah yes, sorry for not updating. I managed to connect my phone to my PC again using the flash tool and then I could flash the original ROM back onto it. I found the ROM by Googling for a bit tho I dont have a link. Be aware that if you do this, it basically factory resets your phone, locking your bootloader again and all. If you do manage to root your phone please contact me as I still have not managed to do so.
Edit: This process of flashing back your ROM always works as long as your phone powers on, so don't worry too much about bricking your phone. I think I've bricked my phone over 20 times trying to root it, and it worked every single time.
Hello there. I suggest that you use "fastboot boot recovery.img" than using "fastboot flash" if you are not sure if the custom recovery works (or if you just want to test/try it). In this way, you'll just boot the custom recovery temporarily (and your stock recovery is still in tacked).
For rooting your device, first you'll need a working custom recovery for your device (you used TWRP, very first if it works or compatible with your device).

Hi.How you actually managed to connect your phone to PC using flash tool if you were in a bootloop and had no access to fastboot mode or recovery?

Im interested too in your process to flash TWRP again, as i am in the same boot loop than you with a Doogee S60. I´ve waited till the battery ended, but now flash tool doesn´t recognize my phone. If i charge the battery, i get a boot loop again..

I have managed to get the flash tool recognizing my phone.Had to keep pressed volume up,if i recall properly(or try volume down) before connecting usb cable to phone with flash tool opened and . It was a while ago though and i can't remember exactly which key was for sure. Hope this helps
I am currently trying to install LineageOS on my phone. I personally have never unlocked or reinstalled a new operating system on my phone. I looked on some XDA forums for some guides and i found one and followed the steps. I unlocked my phone and I installed a custom TWRP because I was trying to downgrade the phone back to android 11. Once i was done flashing the file to the phone and rebooted it doesn't boot anymore and only gives me a booting screen for a few seconds after I hold down the power and volume up button for a few seconds nothing else works. I have use the MSM tool and put my phone into EDL mode and it detected the phone with a black screen. Every time I use the tool it works till about 18% then it gives me a Sahara communication failed error and then my phone gets out of EDL mode.. I installed all the drivers needed on my PC and used multiple USB 2.0 slots but it still fails. Any help would be appreciated.
There are warnings in the TWRP thread for the N200 that it is broken and should not be flashed.
I have written an easy to follow guide here to downgrade to A11 with Fastboot Enhance.
Unfortunately, now that you have used MSMTool on the phone, it is now bootloader LOCKED. This tool should be the last resort only if you are already hard bricked. You could have gotten the phone into fastboot if either boot.img was still intact and re-flashed the rom with a still unlocked bootloader. The phone will change slots after so many failed boots.
Now that your boot loader is locked, the only tool that can modify the phone is MSMTool. If you can get into Recovery, do delete user data and try again.
Otherwise, you will need to get an RMA and send phone back to OP.

Sorry I should have written more details but I currently have a hard bricked device. It will not boot and It failed to boot like 20 times. It will not enter fastboot or even get past the logo when you first turn it on. I did use MSM tool after it wasn't letting me into fastboot. Thanks for the help and I will send it back.
