[GUIDE] [E980] Fix soft bricks. Flash back to stock using LGFLashTools

I realized there aren't any guides [in English] around here to help rooted folks that soft bricked their LG PRO to restore it back to factory settings. This should be useful if you got your phone stuck on the AT&T or the LG logo. Especially now that we don't have an unlocked bootloader or a recovery to reocver our soft brick.
Anyway, to start, a little disclaimer: I hold no responsibility if this method renders your phone completely useless, or burns and makes some nice fireworks. I'm simply writing this to document the process that worked for me. Use at your own discretion.
Dislcimaer 2: this method will wipe out your internal sdcard, apps data, everything! It'll restore the phone back to the way you got it from AT&T. Might even lose your cell unlock status (not verified). so keep these unlock codes handy just in case.
Note to linux users like myself: get your a** on windows or run it from a VM. VirtualBox with Win7 works fine.
Steps:
Download
1. LGFlashTools v1.5. Anything less won't work. Mirror: HERE
2. DLL file for LGE980
3. Drivers
4. The stock image file
Thanks to IOMonster for hosting these biga** files.
Install
1. Install the LG drivers downloaded above.
2. Install LGFlashTools v1.5 (but don't run it)
3. Extract the DLL and the TOT files from above and put them in a nice tidy directory
Drivers initialization
1. Put the phone into download mode. (Turn off device, keep pressing volume down while plugging in the micro usb cable. If this doesn't work, try holding both volume keys instead)
2. Let the phone initialize and install the drivers. Once done, in Device manager, you should see the LG phone listed under COM ports (something along these lines).
3. Find that LG entry in Device Manager, click on Properties, Advanced and then change the COM port to COM41 and close/save.
4. Unplug your phone! Important step.
LGFlashTools
To get this tool to work, you'll need to do a few tricks.
1. Set the computer's date to some time in July 2012 or before.
2. Disconnect the internet
3. Find a serial number or register key from somewhere on the web (a google search for lgflashtools serial will yield some results). Can't help you here and please don't share any keys in this thread or get us in trouble.
4. Execute the LGFlashTools. It should ask you for a key, put it in. Now you should see a dialog where you can load the DLL file and the TOT files that you extracted earlier. Put them both in here. Click ok
Flashing
5. There is a yellow arrow on the top left. Click on it to initialize the process. Once done, it should say "ready/finished" or whatever.
6. Put the phone in download mode again, and plug it into the USB port. LG FLash Tools should start flashing it automatically. When it's done, it'll automatically reboot into your stock AT&T rom and all of your data and internal sdcard files are gone.
Profit

Thanks again Mac !

Thanks .... great info!!!!!

Nice. Hopefully they sticky this.

Welp, just bricked the phone again but was able to flash the tot... very simple and quick lol ur the man mac

this worked perfectly fine for me. i 1st tried it on w8 but after plugging in the e980 and letting the drivers and such install, it did not show up under com in the device manager. in fact, there was no com section. it did show up under devices and printers and i tried and could not find a com setting there. i went ahead and tried to flash but since i could not change to the proper port, the flash tool never found my e980.
so instead i just did it all on a w7 box, the device was listed under com, and i went along with the flashing.
thank you.

Think this will fix the bricks that are happening when they try to mess around with the bootloader?

Nope. Mess with the bootloader and you'll risk losing download mode.

nvm

My friend just bricked his and the wi9ed the system. I can get ir into download mode for him but thats it. I tried recovery mode but trying to do that or boot regularly it just shows lg the an android with the spinning symbol on it the lg again then lg 2 more times and just stays there. Can this be fixed with only download mode? Again I plugged it in and im not sure its being seen by the computer.

Make sure you have the drivers installed and use pc suite to get back the firmware

it doesn't hurt to try. I'll bet it will because I was left with something similar and this method got me back on stock.

Pc suite? Do you mean lg flash tools? I downloaded it but it wants me to log in to use it. I havent found a log in for it yet.

Download lg pc suite it have lg flash tool in it
Then you search a little in menus for firmware urgence recovery something like that and if it don't work try update in the same menu
And if all of that didn't work I'll find you a link to flash a kdz

I seem to have an issue with my E980, i cant get data my apn directory is empty and cant seem to add an apn it will just not save! anyone else have this issue or know what i can do? thanks!

Reboots to recovery only
Ok, I flashed the recovery in this post using the dd method http://forum.xda-developers.com/showpost.php?p=43460298&postcount=208
The value pack was trying to download on my phone and instead of cancel, I pressed install. Now the phone only boots into that recovery. I have everything from the op downloaded, but instead of download mode it only boots into the recovery, any ideas?
When it boots up, It says the following for a couple of seconds:
Code:
Secure booting error
Cause: Device Unlock, so boot success!!
Edit: Got it into download mode by holding down both volume keys and plugging into usb. Thanks!!

Solution for Hard Bricked LG G4 (9008)

Hi guys,
Some people including me faced Hard brick issue with LG G4, which has now two solutions. the first is temporary, i discovered it and it involves using an SD card flashed with Original EMMC dump ( i tested it with H815 ands H811) , the second needs advanced hardware, equipment and soldering skills ( JTAG) .
The solution that i want to explore is trying to revive the phone with the SD card.
http://forum.xda-developers.com/g4/development/unbrick-lg-g4-h811-9008-qualcomm-t3456417
http://forum.xda-developers.com/g4/development/unbrick-lg-g4-h815-9008-qualcomm-t3452853
The H811 dump that i made has TWRP recovery and unlocked bootlloader, so if someone know how to help that would be awesome.
How ???, its very simple. I dont have very good UNIX architecture skills , but if the SoC successfully booted from the SD card. We could see if it detects the EMMC memory ( with parted or with LS command). I personally Tried to brow /dev/block directory from TWRP i hoped to find MMCBLK1 or something but that was unsuccessful , im pretty sure the TWRP or the Soc Does not mount it automatically .
I really dont know How , but i'm very Sure that there is a Solution headed that way , So if some one is Good with Unix architecture and can find a way to soft Flash the EMMC from TWRP ( installed in the SD card ) it would be very Nice

hi,i tried the sd card method...it boots but immediately gives me secure boot error (1006).
i have an h815 bl locked

Hello
I have LG H815 and have bricked. I have installed wrong firmware so it is brick now.
I try new tot file with QPST . but it says fail what s wrong with me?
My computer is win 10 64 bit

You can fix fastboot mode with this way.
1. First you need to download stock rom that your phone supported. extract laf.img file from rom and copy it into fastboot directory
2. download LG Flash Tool and make it ready
3. open flash tool and load firmware and dll that support your model.
open command prompt and make sure you in fastboot directory where the fastboot and related files are stored.
Run following commands.
fastboot erase recovery
fastboot erase laf
fastboot flash laf laf.img
fastboot reboot

Hurry up, now you need to start flash with lg flash tool, if device does not start into download mode. remove battery and insert again, press and hold Vol Up btn and plug USB cable it will boot into download mode. and your device com port should be 41, if not change it in device manager. and start LG Flash tool to load stock rom. once it finish loading rom your device will start and will show you factory test 1, 2, or 3. if it stuck there more than 3-5 minutes. reboot your phone. now you will have welcome screen.
I hope this will work with supported models.

Hello, well after what happened I thought the same and went to buy another battery and when they tried it did not work, I repeat, not fastboot, no logo, no recovery, only a small vibration without screen, it is not detected by the PC in any of its modes as dead, the detail is that this happened after restarting when I had flashed bootloader N, rom V30, magiistic, I gave it restart and it did not turn on again, so I discard that it is hardware .
I think the problem was that I flashed the bootloader with full aboot, that gave me hardbrick I was told in a forum in Spanish I leave the link I hope you help me thanks
https://www.htcmania.com/showthread.php?t=1397519 use this method to unlock the bootloader

Hey MichaelCV
I have exactly the same problem with my LG G4 H815p. I was running [ROM][H815] H-ROM G4 NOUGAT [v29a] _ LG G4. The phone was up and running and last night I flashed the "LG-H815_29a_Modem_and_Bootloader.zip" to try resolve an issue I was having with the mobile data indicator not showing. I flashed the zip in TWRP, rebooted the phone and now it is bricked. I have exactly the same symptoms as you. Windows and FWUL does not see the phone, no matter what combination of keypressed etc that I try.
Lets hope we find a solution here for it.

[help] ZE551ML crashes, TWRP freezes, no connection in xfstk downloader

Hello all,
I'm stuck in different guides on what to do next.
Problem: Zenfone2 doesn't boot most of the times (either looping after the white ASUS screen) or rebooting during loading of CM13.
Also had charging problem, so I unplugged the battery from the back and put it back. This seemed to solve the charging problem. But problems above still persist. Thinking it may have corrupted some memory.
Tried:
- Factory reset in TWRP -> didn't work (the occasion I did get into CM13 it showed the setup again, so the reset actually went through, but loops still exist).
- When in CM13, after letting the phone sleep for a bit (2 mins roughly) - it doesn't wake up from power button. Have to press long and boot again.
- When in TWRP, after pressing randomly some buttons and go back to mainscreen, the touchscreen stops responding too and reboots
- Since TWRP seems so unstable, I wanted to reflash everything using the Unbrick guide via PC.
-> Problem: Cannot get XFSTK to detect the device (Windows says: USB device not recognized or something like that).
- Another problem: When the USB cable is inserted into the device, it sometimes looks like the power+vol up combination doesn't do anything when booting (either the screen stays black or it tries to boot into CM13 and fail.
So now im a bit stuck on what to try next to solve everything and get myself back into CM13. CM13 has ran since Feb '16 and have been a happy user since then until now.
Thanks for reading!

The simplest solution may be to flash back to stock and start over. If the phone doesn't behave properly on a stock ROM, there could be a hardware problem.

Hi there , in TWRP select reboot then power off .
Enter bootloader via buttons after 10 seconds being off !
Enter bootloader - power and vol + , when in bootloader if on LP -- flash raw with AFT (asus flash tool )
If any probs with above , you might have to fastboot flash stock recovery and boot to recovery if/and a , try raw if on LP with AFT or b, sideload stock firmware you flashed stock recovery for.

Thank you for your answers! Last hours been trying to flash the stock ROM back. However, when getting into bootloader, adb devices and fastboot devices don't show the device. Or it even freezes and gets into reboot loops again. So this is why I'm stuck, nothing seems to be working from all the guides and things I'm reading.
So precisely:
- Power off bootlooping device by holding power button
- Power on by holding PWR + VOL UP
- When vibrating: release PWR keep holding VOL UP
- Now i'm in bootloader?
- Connect USB cable to computer
- type adb devices, shows nothing.
So what can I try to make connection?

- Now i'm in bootloader?
- Connect USB cable to computer
- type adb devices, shows nothing.
@j4y_ha .................in bootloader

What ifwi version number in bootloader ?

The bootloader in shows the following:
IFWI version: 0094.0173
SERIAL_NUMBER = F8AZFG0152** (couldn't read the last 2 digits as the device rebooted again). Also sometimes the SN shows 012345689ABCDEF.
I've much trouble keeping the device in bootloader. Last tryings it keeps shutting down after couple of seconds in the menu.
EDIT:
So far the device seems to stay in bootloader mode now. I can cycle through the options normal boot, recovery etc. Below the screen it shows Continue the fastboot process in blue text. I've inserted the USB cable but have been unable to get "fastboot devices" to show any device. ASUS Flashtool also doesn't do anything.
I'm going to try to find a micro SD adapter so I can try flashing stock rom in TWRP from the phone itself (would that be something that could work or is this phone fubar?)

@j4y_ha
Do not attempt to flash stock rom in TWRP ! You will brick !
Flash a custom rom in TWRP only- not one with a mm bl version
You have LP
PLEASE

I have MM not LP.
I don't understand your reply correctly I think so here is what I think you say?:
I should obtain LP rom for ZE551ML
Next, enter bootloader via buttons PWR & VOL UP after 10 seconds being off !
When in the bootloader, - power and vol + (short press or long?) , when in bootloader ->
I connect USB to computer, flash the file using AFT if I make connection. -- flash raw (raw = LP ROM from ASUS) with AFT (asus flash tool )
Thanks again for your help

@timbernot I'm unable to make connection. Fastboot also most of the times freezes and goes to black screen. What could I possibly try now?
Sorry I thought CM13 was MM but then I'm on LP still haha :good:

I'm taking wild guess here that you got wrong TWRP recovery installed somehow or something from M causing all these problems , when you get into bootloader again..Scroll to and select reboot bootloader and fastboot flash stock recovery for LP version you was on .
Then , I guess your problems will be over , where you will be able to flash raw in bootloader or in stock recovery , adb side load the firmware

Thanks for your quick anwer. Will try to get through it haha :good:

DUDEE
that's not a problem.. THAT's like 20 different problems... I bricked the living crap out of my zen the day I bought it (because me = smartypants did not know that the MM boot unlocker is nonexistent so I just tried to root and update from my head using older techniques) and... the XTS tool thingy fixed it..
Don't get me wrong, i want to help but this is the problem that I feel little frustrated with..
Zenfone2 doesn't boot most of the times (either looping after the white ASUS screen) or rebooting during loading of CM13. ## (but it boots sometimes and goes into TWRP, so you have an easy fix to just revert to stock lollipop... why haven't you done that? You sound like you know what most of this stuff does...
Charging problem, so I unplugged the battery from the back and put it back. This seemed to solve the charging problem. But problems above still persist. Thinking it may have corrupted some memory.
## how do you connect this battery issue to your occasional bootloop? Check hardware or firmware and definitely use different threads.. there's no way these are all part of the "same problem"...
When in TWRP, after pressing randomly some buttons and go back to mainscreen, the touchscreen stops responding too and reboots
## Same answer as above - this is unrelated to #2 and unrelated to #1 - is your TWRP the correct one? I mean... did you just maybe flash TWRP version 4000 Modified Alpha for Google Glass??? LOL
When in CM13, after letting the phone sleep for a bit (2 mins roughly) - it doesn't wake up from power button. Have to press long and boot again.
## Is D2W there? "DoubleTap2Wake" ? Are you sure you have a good touch? (this maybe 20% sounds related to your TWRP touch going crazy..)
Cannot get XFSTK to detect the device (Windows says: USB device not recognized or something like that).
## There's this awesome invention called DRIVERS... and we're lucky in this case (cuz I bricked an hour after I bought it) because Intel PC + Intel Phone = Yay... There is even.... a very specific "INTEL ASUS WINDOWS DRIVER" file... from the INTEL AND ASUS WEBSITE... or maybe your USB CABLE is f**? My point is... another unrelated issue where it sounds like you've not even tried it properly before complaining.. I like helping people. I don't like when people refuse to try or they skip the actual study-notes to do it... I used the EXACT same guide to unbrick and it worked in 2 mins... I'm on a 2007 Laptop which overheats if I use 4 tabs... how am I able to follow the exact same guide on a brand new "FULLY BRICKED" phone... it literally would vibrate after trying power button for 5 mins and be stuck in a "blank black screen" for hours and hours... No twrp no nothing.. and I did it - why didn't you? Same guide man...
When the USB cable is inserted into the device, it sometimes looks like the power+vol up combination doesn't do anything when booting (either the screen stays black or it tries to boot into CM13 and fail.)
## Try again. Sometimes people accidentally hit power to early.. or whatever.. It's not a MK2 Fatality.. don't force yourself to get it exact.. Let the menu pop up... just wait a second and scroll up/down just to see if that works... then scroll to Boot-Recov and gently hit power+vUp.. should be fine.. otherwise just .. literally try 10 times.. it WILL work.
Since TWRP seems so unstable, I wanted to reflash everything using the Unbrick guide via PC
## Nope.. TWRP is like Bret Hart. It isn't unstable. Not for LP not MM not for N. Not for Stock Not for CM Not for AOSP. You *wanted* to do what you should have done right at the beginning but you didn't get that done properly (see below)
Essentially you have 8 different unrelated issues (and the biggest one is not reading guides, not trying hard enough and just thinking that people like me sit around and get paid for this)... and want ans in one place w/o just doing the simple thing of going back to everything stock...?? *it's just annoying cuz people who want to help will feel like.... others don't even try simply because we exist and have desire to help...* - I am not trying to offend you but I hope you get my pov.
Do This EXACTLY
#Buy a cable. Borrow a cable. Whatever you do be 1000000% sure the USB Cable is fine
#Install Intel Asus Android drivers from official EXE (google it... don't add new post for that link)
AND THEN
Follow the same Unbrick guide word for word *but* just pay close attention to these:-
IntelSeC Driver + device detected even if OFF (start>devman>showall>intelsec
In the official unbrick utility make sure you're on the second tab at the bottom
In settings check that your device flag is 0x08..... whatever instead of the default 0x000
Back in the *second tab at the bottom* (i don't remember exact name but it's in the guide) -- put the right files (mentioned in guide) in the right boxes.. (mentioned in guide) and remember you ONLY need the DVFWthingy... + TOKENthingy + IFWthingy
Plug the Zen in... hear the "da-dumm" sound... keep looking at the Unbrick tool.. and the moment you see Device Detected = 1 you hit install/start...
AFTER that is fully done *(and if you fail don't post just repeat from scratch)... I don't personally recommend Asus Flash tool it was acting dodgy for me but instead grab the RAW Stock... Rename it to zip.. open it and grab the img files and fastboot flash the fastboot droidboot.img + splashscreen splash.img + boot boot.img + recovery recovery.img
If you've followed all that from the guide and double checked what I've put up there.. you should be fine if you just fastboot reboot bootloader... and go into stock recovery... install zip/update and put your stock OS in there..
Done.
Just please take my advice and don't skim through guides, don't think you don't need to read something, don't click stuff without double checking every line from guide, print it out on PAPER if you need to.... but please don't post like this... and don't use different guides or you will be stuck (as your heading stated..)
Forget everything you knew. Close all other tabs and use this guide thoroughly for Reference:-

Wow @ryankabir
one step at a time hey
xFSTK is used to bring temp bootloader to hard bricked devices .
He has stock LP bootloader and all avenues to repair should be explored first
If anyone needs to unbrick , there is a thread in my signature below ,shows how to go from complete brick , to restoring serial number and into system within 15mins

Thank you for your thourough answer Ryankabir! Much appreciated. My answers are below. I will try your suggestions soon.

Zenfone2 doesn't boot most of the times (either looping after the white ASUS screen) or rebooting during loading of CM13. ## (but it boots sometimes and goes into TWRP, so you have an easy fix to just revert to stock lollipop... why haven't you done that? You sound like you know what most of this stuff does...

Yes I do know what I can do with it, but it just so complicating as there are different factors like the loops, not being able to get connections with USB. I mean, it is not totally bricked since sometimes I can get into TWRP or bootloader.

Charging problem, so I unplugged the battery from the back and put it back. This seemed to solve the charging problem. But problems above still persist. Thinking it may have corrupted some memory.
## how do you connect this battery issue to your occasional bootloop? Check hardware or firmware and definitely use different threads.. there's no way these are all part of the "same problem"...
Click to expand...

Well, since the phone worked fine before the battery issue, there is some sort of link between the issues I would think. Maybe I've broken some hardware during the battery removal or did the booting into charging mode and on/off continously corrupt some memory leaving me with weird crashes & loops.

When in TWRP, after pressing randomly some buttons and go back to mainscreen, the touchscreen stops responding too and reboots
## Same answer as above - this is unrelated to #2 and unrelated to #1 - is your TWRP the correct one? I mean... did you just maybe flash TWRP version 4000 Modified Alpha for Google Glass??? LOL

Although I'm not sure if I have the correct TWRP, it did flash CM13 correctly back in FEB 2016 and haven't found a need to update it ever since as it worked fine during the occasional update...
ryankabir said:
When in CM13, after letting the phone sleep for a bit (2 mins roughly) - it doesn't wake up from power button. Have to press long and boot again.
## Is D2W there? "DoubleTap2Wake" ? Are you sure you have a good touch? (this maybe 20% sounds related to your TWRP touch going crazy..)
Click to expand...
Click to collapse
No, D2W is not there. The phone is totally unresponsive to the power button as well as D2W. When in TWRP the touchscreen functions fine until it freezes at some random moment.
ryankabir said:
Cannot get XFSTK to detect the device (Windows says: USB device not recognized or something like that).
## There's this awesome invention called DRIVERS... and we're lucky in this case (cuz I bricked an hour after I bought it) because Intel PC + Intel Phone = Yay... There is even.... a very specific "INTEL ASUS WINDOWS DRIVER" file... from the INTEL AND ASUS WEBSITE... or maybe your USB CABLE is f**? My point is... another unrelated issue where it sounds like you've not even tried it properly before complaining.. I like helping people. I don't like when people refuse to try or they skip the actual study-notes to do it... I used the EXACT same guide to unbrick and it worked in 2 mins... I'm on a 2007 Laptop which overheats if I use 4 tabs... how am I able to follow the exact same guide on a brand new "FULLY BRICKED" phone... it literally would vibrate after trying power button for 5 mins and be stuck in a "blank black screen" for hours and hours... No twrp no nothing.. and I did it - why didn't you? Same guide man...

Yes I know what drivers are :good: - I've tried IntelSoc, Intel ASUS etc... all drivers that are somewhere mentioned I have installed. Before the charging problem I was able to connect the phone and access files fine as well.
ryankabir said:
When the USB cable is inserted into the device, it sometimes looks like the power+vol up combination doesn't do anything when booting (either the screen stays black or it tries to boot into CM13 and fail.)
## Try again. Sometimes people accidentally hit power to early.. or whatever.. It's not a MK2 Fatality.. don't force yourself to get it exact.. Let the menu pop up... just wait a second and scroll up/down just to see if that works... then scroll to Boot-Recov and gently hit power+vUp.. should be fine.. otherwise just .. literally try 10 times.. it WILL work.

Since TWRP seems so unstable, I wanted to reflash everything using the Unbrick guide via PC
## Nope.. TWRP is like Bret Hart. It isn't unstable. Not for LP not MM not for N. Not for Stock Not for CM Not for AOSP. You *wanted* to do what you should have done right at the beginning but you didn't get that done properly (see below)
Click to expand...

TWRP is indeed fine and stable! However, it freezes and reboots my phone so in my particular situation it is currently not stable. Therefore the need to completely wipe the phone and start from fresh.

Essentially you have 8 different unrelated issues (and the biggest one is not reading guides, not trying hard enough and just thinking that people like me sit around and get paid for this)... and want ans in one place w/o just doing the simple thing of going back to everything stock...?? *it's just annoying cuz people who want to help will feel like.... others don't even try simply because we exist and have desire to help...* - I am not trying to offend you but I hope you get my pov.

Appreciate your POV. I know how it feels like if people ask for help for something they could have read easily somewhere. I'm thankfull for all the guides that people have written on here! I'm asking for help because in my situation the guides are not working and would like to have a full clean wipe of my phone and fix all possible software issues before trowing away the phone because of hardware fault.

Do This EXACTLY
#Buy a cable. Borrow a cable. Whatever you do be 1000000% sure the USB Cable is fine
#Install Intel Asus Android drivers from official EXE (google it... don't add new post for that link)
AND THEN
Follow the same Unbrick guide word for word *but* just pay close attention to these:-
IntelSeC Driver + device detected even if OFF (start>devman>showall>intelsec
In the official unbrick utility make sure you're on the second tab at the bottom
In settings check that your device flag is 0x08..... whatever instead of the default 0x000
Back in the *second tab at the bottom* (i don't remember exact name but it's in the guide) -- put the right files (mentioned in guide) in the right boxes.. (mentioned in guide) and remember you ONLY need the DVFWthingy... + TOKENthingy + IFWthingy
Plug the Zen in... hear the "da-dumm" sound... keep looking at the Unbrick tool.. and the moment you see Device Detected = 1 you hit install/start...
AFTER that is fully done *(and if you fail don't post just repeat from scratch)... I don't personally recommend Asus Flash tool it was acting dodgy for me but instead grab the RAW Stock... Rename it to zip.. open it and grab the img files and fastboot flash the fastboot droidboot.img + splashscreen splash.img + boot boot.img + recovery recovery.img
If you've followed all that from the guide and double checked what I've put up there.. you should be fine if you just fastboot reboot bootloader... and go into stock recovery... install zip/update and put your stock OS in there..
Done.
Just please take my advice and don't skim through guides, don't think you don't need to read something, don't click stuff without double checking every line from guide, print it out on PAPER if you need to.... but please don't post like this... and don't use different guides or you will be stuck (as your heading stated..)
Forget everything you knew. Close all other tabs and use this guide thoroughly for Reference:-

Wow @ryankabir
one step at a time hey
xFSTK is used to bring temp bootloader to hard bricked devices .
He has stock LP bootloader and all avenues to repair should be explored first
If anyone needs to unbrick , there is a thread in my signature below ,shows how to go from complete brick , to restoring serial number and into system within 15mins

I've tried your guide but I still have been unable to get a connection with ASUS Flashtool. The phone does keep itself relatively stable in bootloader (don't know what fixed it) - I am able to cycle through normalboot, recovery options etc without it crashing. The bootloader shows "Continue the fastboot process". I have tried different drivers, while rebooting between install/uninstall of drivers.
Thanks again all for the help

Right m8 , we gonna fix your phone .
Do not stray from this guide.
Stick to it and you will be more the wiser when you have finished .
1 boot to boot loader ...scroll to 'power off ' and select it.
2 Connect your phone to wall charger ...let it charge till full.
When that's done , we ready for next step

Just a bit curious what the smileys in line 1 and 2 actually meant.. any hidden snarkasm these?
As for the LP stock BL he has.. after reading through the various (and really insane bugs)...

So essentially he could be fixing it al but we often totally overlook TX " RR... becausee his type has ben Mania

There is defin

Mmbl came about around July 16, he run cm 13 Feb 16.
.173 or .177 is unlocked or locked LP Boot loader.
xFSTK is to gain temp Boot loader.
He gets recognised in fastboot.
He can flash stock recovery .
He can sideload .
.
.
But
Can he ?
That's not sn ide btw

Well I'm not gonna dig too deep into the twrp touch issues (there could be conflicting drivers or even something weird i noticed in twrp302 anything below 20% batt (or if batstats corrupt) then the touch goes craycray.. so lets ignore that..
this thread is getting too heavy i won't have time - so - you can always backup ur data partition so no worries there.. nothing to lose..
one problem at a time.. as I said in first post my phone was bricked much worse i had mismatched fastdroidboot and bootimg and after pressing power on maybe 4-5 times.. it would only turn on once.. sometimes on and immediately off... sometimes on stuck on logo.. sometimes on and no logo but screen is black (corrupt splash)..
so lets just try to go baaaaaack to the futureeeeeee ... Ok I found the script I made (after 8 hours of trying EVERY combination from different guides I just took individual components and made my own.. ) -
I'm writing this in a hurry so please use my first reply to get the XFTS Ubrick Guide for the Files + get the LOLLIPOP One Click BL Unlock + Lollipop Raw image... Their Guide wants you to use Asus Flash but that program failed me every time... so I have got a differnt way to do it..
I'm copying this directly from my own script (so you can change if any paths/names different)... but do not change the order or sequence
Using OneClick (keep the unlock1234 files saved separately for later use)...
If you have these unlocked I just say do it again anyway - no harm...
Unlock Bootloader for LP Stock (even if you have MM you must downgrade by this same method)
Code:
#flash old droidboot for LP stock Bootloader
fastboot flash fastboot droidboot_2_20_40_197.img

# must run reboot bootloader once with this droidboot before continuing - dn't skip this

#if you get failed/error at oem stop - reboot to Bootloader (VOLUP+Power long press -
Release power at Asus Logo or long vibration) and re-do the last step
#if all done so far
fastboot reboot-bootloader
#white Asus logo means unlocked loader
fastboot flash recovery twrp3.img
reboot-bootloader
#toggle Up to choose Recovery - quick tap VOLUP+Power
#twrp will start
install Custom_MM_Rom.zip
#likely it will fail giving IFW 7 error - (intentionally did NOT put MM BL here), so

#let it be fully done, verify working MM stock OS
#check if it works - *sign* test your touch screen quickly and in dev tools Keep Debugging ENabled

bricked zenfone 2 ZE551ML

Hi,
long story short:
- worked for few hours, then refused to start, black screen, just vibrating
- bought it from my mom, by the time I got to see her, too late to retrun the phone. Seems like was a chinese import (I'm in France) so no ASUS support and too late to return it to seller...
- so tried to unbrick it following https://forum.xda-developers.com/zenfone2/help/thead-bricked-phone-updating-to-mm-tips-t3452785.
- Got the first steps ok (xfstk done)
- time to unzipthe stuff etc, phone turned off and PC rebooted for whatever reason
Where I'm at right now:
- nothing happens, not a vibration, not a detection in device manager, nothing... (I charged it)
-When plugged into computer, after a while, gets hot (more than battery charging, means CPU working like hell?)
Seems like dead for good? any hope to "reanimate it" at least to the fastboot to resume the precedure?
Thx much for your help, buying another one would be ... super sad and difficult
Cheers!

Try to flash using asus flash tool.
1. Download the lollipop raw firmware.
2. Asus flash tool
3. Drivers .
Now start the flashtool then select your device model from list then browse for the raw file that downloaded.
Now connect phone in boot loader mode.
Then click start it will take some time to flash. During flashing phone restarts at that time again boot it to bootloader mode.
You will loose total internal storage data.

that's the issue, can't enter bootloader mode (phone remains completely dead even if charged, no vibration, screen remains black etc)
thx anyway

How to "debrick/unbrick"an oppo find 7/7a

Greetings,im Akmal and today I will be sharing some helpful solution to unbrick your Oppo Find 7/7A.​Short Story(myb a lil bit longer)¬
So my find 7A got soft bricked when I install custom rom without using TWRP(pretty stupid to do so)
After rebooting my phone keeps on booting to fastboot mode and no matter it happen the same if i press vol up/vol down and power button.
At this stage I knew my phone is soft bricked.So I found the solution to it through some old posts which you have to extract the ColorOS blablabla and adb thingy(I dont wanna go through it here)
But I dont realised that i forget to flash a file name "TZ.MBN"
Now that my phone wont ever boot or even to fastboot which resulted to hard brick.
No recovery screen.
No Charging status screen
No Fastboot screen
No sign of vibrating when i push the power button
-So here is the solution-
Disclaimer-I am not responsible for what ever happen to your device after this-
-there are already some other posts like this but I make this post to let you know that its still working.
1a)First,download the OPPO UNBRICK TOOL HERE
bit.ly/OPPOUNBRICK
1b)goto Google and search for Qualcomm qd loader.download,install and restart your pc.
2)After restarting,Extract the file from OPPO UNBRICK TOOL and open "Msm8974DownloadTool.exe"
3)as you may have notice,its chinese language or some aliens language but dont worry it isn't corrupted,just follow through↓
4)disconnect your device battery,then open the software and press start,after that connect the phone to your pc/laptop (WITHOUT BATTERY) and hold volume up button
5)please wait patiently as it is reflashing stock rom to your device.
6)as you may have noticed maybe your device disconnected but DONT GET PANICKED! press again the power button until its downloading again on the software.
7)If it has done downloading,some row should be in a Green colour.
8)disconnect your cable and try turning on your device again.
That's it!Any comment or curiosity I will try helping you through the comment section but I not guaranteed everything I can answer
P/S:if your device is softbricked,you just should disconnect your battery,and then open the software and press start,then connect the phone to your pc/laptop (WITHOUT BATTERY) and hold volume up button.
If your device is hard bricked(like mine)only holding the power button could work as well
*UPDATE* 24/2/2019
-If you guys still have any concerns kindly contact me through twitter (0728mal)
*UPDATE* 4/7/2020
-yes it is still working guys,no worries kayy
-no you don't need internet for it to work,the software already has all the files needed to flash the device,which is why the file is pretty big.
best regards,
Akmal

5)back to the software,no need to mess around with it.Click on start until its downloading a "new life" to your phone.

hi im having this problem as well. my find 7a is hard bricked after i flash coloros v2.1.5i without twrp. the problem is, my computer does not detect my phone at all even after i hard reset and hold power button for 30 seconds. i dont think the battery is drained because before this happened, my phones battery was about 90% and i try recharging the phone for 30 minutes, and nothing happened. so the debrick tool cannot be used. can you suggest anything for my problem?

Got excited when I read this post! Is there an Oppo Unbrick tool for Mac? I don't have a Windows machine so I can't run the .exe file... Is there an equivalent for those of us not on Windows? Thank you

On Mac's OS, you can always install Windows on its proprietary virtual machine and get the process going that way.

hello there!I'm really sorry for not checking this that often and really sorry if i let you down because im too busy with my schools work
btw before my computer can detect my phone i have to download a driver which detect qualcomm processor for my oppo then it can be detected by my pc therefore i can do the unbrick process:good:

yeah you can try WINE also but i never have any experience with mac os before so i cant guarantee that it will work considering that you're configuring your drivers,which can go wrong if not done correctly

So I have bricked my phone (X9006) while trying to install TWRP recovery. It is stuck on logo and adb/ fastboot does not recognise it anymore. I have tried the above-mentioned tool, but this program also does not do anything for a long time. Am I missing something in applying this solution?
Edit: I am an Windows 10 and I might not have the Qualcomm drivers installed. I don't know how to install

Hello there.have you tried downloading the "Qualcomm"
Driver software on your PC?

is it necessary to remove the battery? I don't have tools for opening my phone and it's battery is non-removable

Perhaps an important step is missing. The Qualcomm qd loader driver is may not signed. I had to boot into the extended start menu on Windows 10 and disable the driver signature check - point 7 - and could now successfully debrick my find7.
