Need help ASAP, can pay for you to fix my phone

Apparently my phone is bricked..
I rooted my phone a long time ago when I first got it, never installed any roms or anything.
I get this message on the LG Screen:
"Secure Booting Error problem
Device UnLock!!, so Boot Success!!"
I've tried multiple ways to fix my phone and I can't get any of them working.
I'd be happy to pay the person in a steam game of your choice!!!!
Thank you

I tried but the drivers won't install correctly. They did once, but it just said something along the lines of "Ready", and never did anything even after plugging and unplugging.

Uninstall and reinstall drivers ... Try different computer. Lg flash tools should fix your problem . goodluck

That message upon boot is normal if your phone has been modified. Mine says it too and my phone is booting up perfectly fine. In fact, it always has said that from the day I first modified it.
Most likely your software is just bricked. First of all, BE HAPPY YOUR PHONE IS JUST SOFT BRICKED! :laugh:
(I recently hard bricked my phone by accidentally flashing a file for a completely different phone... phone was completely dead!)
You need to provide more info for anyone to help you, whether it's me or someone else:
1) What phone are you using? E980, E988, E986, F240, etc etc.
2) Do you have a custom recovery, like CWM or TWRP? (I'm hoping you are because getting software back will be easier).
2.1) Can you boot into this recovery? (hold volume up and power button at the same time. The boot animation will begin and the screen will then shut off again. Once it does, let go of the power button, but keep holding the volume up key. The phone should reboot into recovery. It's tricky to do, and if any other readers notice that I described it wrong, please correct me!)
3) Do you ever see the LG boot animation? (The animated LG logo)
4) Once you see that message upon boot, do you wait for it to pass and hope the phone boots, or do you panic and force the phone off?
5) To get the drivers to install for using LG FlashTool, have you done the following?
- First download and install the drivers from the LG site (I'd link you to it, but I only know the link to the E980 drivers. I don't know what phone you have).
- Once installed, plug your usb cable into your computer, but not the phone.
- Hold the volume up and volume down buttons at the same time while plugging the usb cable into the phone
- Phone should now boot into Download mode and your computer will start installing more drivers. Let them install.
- Change the Com port of the phone to Com41 (ask if you don't know how to do this)
- Continue using the LG Flash Tool.
I apologize if any of this sounds like I'm insulting your Android phone intelligence. I don't know how much of this stuff you know.

No, no I understand!
1)E980
2)I have TWRP.
3)I only see the LG Logo, the error message and that's it, it goes right to TWRP after that.
4)I wait for it to pass, and it goes to TWRP.
5)I will try this on a different PC, because when I boot into download mode and plug in the phone, the drivers attempt to install but fail. I have attempted to re-install them multiple times, but I'll give it a shot on my laptop tonight, and let you know if that works.
Thanks for the help, and I may PM you later!

Have to tried install cwm through twrp then wiping clean and installing a ROM ...
2SHAYNEZ

Me thinks his botloop is due to a bad rom flash, flash a rom(EZ kat is a good choice if you want the AT&T stock experience). follow shayne's instructions.

@AustinBobDox:
I know EXACTLY what the problem is. You ran into the notorious recovery bootloop, which seems to be happening to many Kitkat users running recoveries incompatible with KK.
I had it a few times myself while using CWM, PhilZ Touch, and TWRP (Yeah, I got them on all 3!)
Unfortunately, the TWRP and CWM recoveries posted in this forum cause this bootloop randomly if you have the stock Kitkat rom installed (whether rooted or not). Personally, I have not been able to get out of it. I ended up flashing a "fix" that was supposed to get me out of it, but... it was for a completely different phone (an HTC) and it hard bricked my phone.
SO DON'T FLASH ANY "FIXES"!!!!!!!!!
Technically, the ROM is perfectly fine. I read that this bootloop is caused by the phone setting a flag that tells it to boot straight into recovery. Basically, when you initiate the recovery boot, it sets this flag, and when you reboot the phone, it's supposed to clear the flag. In the case of this bootloop, it doesn't get cleared for some reason.
Luckily, since you are on TWRP, you can try this:
Open the TWRP command console thing (I think it's under Advanced or something).
Type this command EXACTLY:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
DOUBLE CHECK YOUR SPELLING, SPACES, ETC!!
EDIT: I put a part in bold because it's .1
The decimal could easily have been missed if reading on a smaller screen or something.
Submit the command and try to reboot to system via the TWRP menu.
If this doesn't work, then you have no choice but to use the tot method once you get it working.
EDIT: Oh and before getting the drivers to install by plugging in the phone, install these drivers:
http://www.lg.com/us/support-mobile/lg-E980
(Look under Software Update tab)
Whether the command works or not, once you get the phone up and running again, install this recovery:
http://forum.xda-developers.com/showthread.php?t=2760895
It's the only recovery right now that's definitely working on Kitkat without the bootloop issue. The only downside is that it can't mount the external_SD, so anything you flash must be on the internal storage.
EDIT: Oh and in case you can't tell, don't flash this recovery! You install the APK in Android and then open the app and install recovery from there. You need to root first though.

With this recovery bootloop, even if you flash a new rom, the bootloop could remain. I wasn't able to try a whole new flash, but I did try restoring a backup (different things, I know) and I still kept booting into recovery.

Oddly enough, this has happened to me on all cwm versions, flashing the hacked twrp was the only way i could get out of it. I use cwm to flash roms, twrp i only use when in bootloop or to flash mods.

Help - Stuck on Download Mode

I rooted and flashed Sphinx. The ROM somehow kept me from hearing the other person on the other line when making calls and they couldn't hear me. So I was trying to unroot by using the Flashroot tool method. And now I'm stuck on download mode.
I have a d855. How do I unroot properly and how do I get out of the download mode.
This is my first time rooting an LG phone :/

Hold the power button for 10 secs to reboot to normal. <<<<<<<< Depending on what you have done >>>>>>>>>>
ENSURE that no transfers or other process are in progress or you will have a bad day. I don't know what you have done on your phone but ensure you read the thread you are following completely.

The method failed, so I gave up and wanted to just reboot. Did a batter pull and was able to get to the factory reset screen, but it just loops back to download mode.

follow this, for your variant, it should get you back on track don't forget to check the hashes as a bad download would cause it to fail.

I don't have the links to the tread where I got these from but lets just hope I don't get banned.
1) go to download mode
2) install this and download the correct .kdz file for your phone
-Modelnumber is ...
-serial number is your imei number
- wait until the download is done
3) run the lgflashtool2014.exe from this zip
-Select type= cdma
-phone mode= Diag
-reset time=33000
-Should be like this when You run it
-select kdz file= is where you need to find the kdz file you just downloaded(step 1)
-then press cse flash
-in the now pop-up window select start
-select your language
-ignore error (cannot connect to lg server)
-check progress on phone up to 100% then boots in recovery installs and restarts
-wait untill it goes to the welcom screen then you can unplug
-now the most inportant step Like my post
to enter download mode do this:
--You must switch off the device to start the process.
--Then press and hold the “Volume Up” and connect the USB cable from phone to PC.
--Use the original USB cable. Because, other device’s cable may not be detected in the Computer. So, only we recommend it to use the original-- one that you got it when you bought the phone.
--Wait for the driver installation on PC.
--Then you will get the download mode screen in your phone.
--That’s it.

I have the opposite problem, can't get into download mode haha

I can't find the .kdz file. I have the D85010d.
Also, i ran the original lg firmware, I also get an error saying it was unsuccessful or i may have keyed in something incorrect.
When I run perform the TOT method, I get the "device model is different".
So, d85010d was stock and I flashed sphinx d855... where they incompatible? im assuming no because the phone ran fine aside from the issue i stated on the original post.
would like more help.

I tried everything TOT& DLL files KDZ Files no thing work for me.

I have the same problem im stuck in download mode and i cant find the kdz =O
I need to know if something can resolve this problem , my device is a lg g3 850 10 d and i installed the room sphinx for the lg D855 and was incompatible because the dialer did not work properly and try with original tot for my device and dont work with this method.. so i need the ORIGINAL KDZ for the lg G3 D850 10d know where to find???

I was in your position. Once you enter the download mode it is *almost* impossible to get out without removing the battery. I've heard a lot of suggestions like pressing the power button for 10 or 20 seconds or even doing that in combination with other keys, BUT the ultimate truth is that you have to press and keep holding power button for at least 1 minute. I didn't time exact seconds, but it was ridiculously long time. Probably it will take you less time removing the back and re-sit the battery, but personally I hate removing the back without serious reason
About the second question - I was unable to flash anything in LG's download mode. I'm using Ubuntu + virtualbox (Windows 7 inside), but due to issues with drivers and/or virtualbox and/or usb port forwarding I was unable to reliably connect and flash the stock kdz image. Fortunately I've sent the phone back to the LG repair office and they re-flashed the firmware for me.

It is not exactly what you want, BUT at least you can get your latest, official KDZ file from LG.
Open in browser the following URL, but replace the xxxxxxxxx
http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=xxxxxxxx
where xxxxxxxx is your IMEI number
As a result you'll get an XML file that will contain the location of your latest KDZ update, which should look something like this:
http://csmgdl.lgmobile.com/dn/downloader.dev?fileKey=.../D85510L_00.kdz

If you can't get in that, then something very serious happened!
you sure you can't enter it?
Otherwise, it would mean you messed up the bootloader!

i am also having lg g3 F4ooL
installed cloudy g3
soft bricked
boot looping
when i enter into download mode
flashtool says an error that
*cant change to Download mode*
Download fail
what can i do?

Hi guys, i know it's an old post but i get the same issue.
I was following this tutorial https://linustechtips.com/main/topic/1058206-lg-g3-lineageos-tutorial/
I was on lollipop.
I initially downgraded to kitkat (V10e) using LG UP and then rooted with purple drake.
In the following reboots, "kernel error" occurred.
So I tried to flash the kitkat stock version again but without success.
I'm stuck in download mode and tried to flash both the kitkat version, the lollipop and the marshmallow, through .tot and .kdz, I tried both with LG UP, LG Flash tools v 1.8 and with LG flash Tools 2014 but in all cases unsuccessful because the phone reboots before it ends.
Now I don't know what to try anymore. Do you have any solution, please?
Thanks in advance.

[Q] How do I get download mode working?

I rooted my phone about a month ago using PurpleDrake and now I'm on SkyDragon G3 V0.0.5 w/ TWRP. I had never been able to boot into download but thought nothing of it since it wasn't crucial at the time. Then, yesterday I accidentally took the new OTA update, but was able to fix it with the ADB commands that others have posted. Being able to get into download mode would have made life easier so I tried to fix it today. Flashed stock boot.img and tried to re-run PurpleDrake to see if I missed a step but it won't detect my phone for a reason I don't know. At my wit's end.
Not being able to get into download mode is a concern in case I ever to fully return to stock. Wondering if any one has some insight on how I can do that or if there's some image file I need to flash, etc.?
Thanks!

Thanks for the reply. Sorry, I could have been more clear in my post. I have visited that thread and held volume up while plugging my phone in, but all that happens is the LG logo screen pops up for a few seconds, then the phone shows the charging percentage. When I try to do it from the advanced reboot menu when the phone is powered on, it simply reboots into the system. Same deal if I try to do it from TWRP. Really not sure what I'm doing wrong here. Is it possible that I somehow corrupted the bootloader or something else that's hopefully fixable?

I think you made a wrong procedure.
Take the battery out and put back in.
Press and hold volume up button.
Plug in the cable.
Release the button when you see download mode screen.
In addition, make sure you have LG PC Suite with phone driver installed.

Thanks but I have already done this with the same result as I've described. I know how it is supposed to be done with the hardware keys and I am using the stock data cable. Even watched a YouTube video demonstrating how it is to be done. Are there any other possibilities?

Just tried it with my nexus 7 cable on a different usb port (which I had done couple times before) and it worked this time! Not sure why or how but appreciate the help, everyone!

LG G4 H815 - Stuck on Bootloader State

Hi to all,
yesterday I attempted to install LineageOS on my LG G4 h815.
I followed this tutorial -> https://forum.xda-developers.com/g4/general/howto-complete-guide-to-unlock-twrp-t3370003
Everything went fine. I was able to boot under LineageOS reinstall my apps etc, etc.
This morning when I woke up everything seemed normal too. But, few minutes ago, I sent an SMS via Google Messages the phone froze and then black screen.
When it froze I had 97% battery.
Ï tried to reboot it with power button -> Nothing.
I tried to remove the battery put it back on and pressed the power button -> One tiny vibration but nothing
I tried several times the same last process and finally I managed to get the screen with "Bootloader state : Unlocked !", but I cannot go further.
If I connect the phone with a USB cable, wether he's "turned on" or turned off no led is blinking.
Does someone have a clue to fix this or has ever encountered this issue ?
Tanks in advance and do not hesitate to refer to an old post. I wil check (but found no same case).

Hi to all,
yesterday I attempted to install LineageOS on my LG G4 h815.
I followed this tutorial -> https://forum.xda-developers.com/g4/general/howto-complete-guide-to-unlock-twrp-t3370003
Everything went fine. I was able to boot under LineageOS reinstall my apps etc, etc.
This morning when I woke up everything seemed normal too. But, few minutes ago, I sent an SMS via Google Messages the phone froze and then black screen.
When it froze I had 97% battery.
Ï tried to reboot it with power button -> Nothing.
I tried to remove the battery put it back on and pressed the power button -> One tiny vibration but nothing
I tried several times the same last process and finally I managed to get the screen with "Bootloader state : Unlocked !", but I cannot go further.

If you can get it in to download mode use you laptop to flash recovery this is probably why it has failed.......remember Google s your friend.

Just to perfectly understand.
Are you advising me to flash my recovery with an older version via my laptop (I imagine via adb/fastboot) despite I can't even get my LG be recognized by my laptop ?
Will the adb/fastboot command be functional as the LG seems not to be recognized on the PC?

The best way to get your laptop I recognize your phone is to get LG up running then with the usb plugged n drop the battery out then put battery back in then close off LG up.
Then start it again and when it go's into download mode the pull usb and close off LG up Then plug it back in with dos prompt open............

Thanks for your reply and your time. I didn't know this software "LG Up", I will give it a try this evening (in France ^^') and give you feedback then.

LG UP had no effect on the phone.
However, now the phone seems to have 0% battery and when I try to boot it I get the graphics to plug the phone on a source of energy. Once I do that the front led is blinking in orange (I guess because I had less than 1 or 2% o battery) and now the front led is still lit on in orange. Is this a good news or I'm hoping for nothing.
Anyway tomorrow I will try to get it back to my retailer.
Does anyone succedeed to get it replaced by LG even if the bootloader is unlocked ?
Thanks.

After a little journey to the repair shop of my retailer everything seems to work correctly, for the moment, with LineageOS !
Thanks everyone for your help !

You have either bricked the phone or its not the correct rom,
Try a different rom, Maybe you can restore it with TWRP if you installed it, Or try download mode.

Make sure its for the correct model, I have a LG K10 the firmware is on the LG site but I have a At&t model which doesn't have official firmware from the sites. To get into android recovery which might help see your phone is bricked install ADB and Fastboot and run "adb reboot recovery" Also some LG phones don't have Fastboot like the At&t of the LG K10 Which I have. Hope you can get it to work
---------- Post added at 04:02 AM ---------- Previous post was at 03:58 AM ----------
Also try Safe mode, you could try it maybe you can get into it, so if that is the case, its probably something with what you did or how you flashed, if you still can't get it to work maybe wrong firmware.

Adb doesnt find the phone i only can get into download mode and there it doesnt get recognized
My phone hasnt got fastboot too
I tried many firmwares now, neither of them work i tried to do it with lg bridge and it doesnt work either all of the firmwares where for my lg k10 m250n
Is there another way to get into recovery
Bit more information:
When i try to start it in safe mode it shows lg logo goes for a short while to a screen where it shows "erasing" then just goes to lg logo again.
And again another thing: the phone behaves the same if I flash the wrong rom it does the exact same.

How do you try to start that safe mode? What buttons you used?
>Is there another way to get into recovery
Go into download mode and using Send_Command
or lglaf.py give it this command: multi_init
There push Vol+ and then Power once.

Wow didn't thought someone reply to this after the long time I just say thx for response even if it's not workin
I don't even know which buttons I used for safe mode but I can look after it later
I'll give it a try with the python script when I get to my pc tomorrow
Will be Posting the results directly after
Also 2 more questions
What does the recovery look like on the LG k10
And can I flash custom recovery zips with that?

The Send_Command might be easier. With that py you have mod it a bit and use an older version drivers. Was it 4.04 or something, then it works.
If you're using Windows that is... Then there is Steadfasterx's and some other lglaf versions that might work...
With send_command you just find the the COM port the diagnose or whatever uses, like:
reg query HKLM\hardware\devicemap\SERIALCOMM
And then: Send_Command.exe \\.\COM[com port number]
Send_Command.exe \\.\COM22
Then you can give that command, and by default it will boot to the recovery.
In recovery there is that dead android guy waiting, that's why those buttons.
Custom zips: No way. Now keys to sign them... and the bootloader should be
unlocked to do any changes...

Basically the factory reset. Fastboot/bootloader doesn't work.
>There push Vol+ and then Power once.
edit: Actually, it is other way around. Push Power and then Vol+ once.

Actually, try with Vol- if Vol+ doesn't do the trick. Don't remember these so well anymore.

I don't have the bootloader too but I guess yours Is locked too like mine
But that doesn't help me.
I have download mode and recovery mode where the only option is to factory reset it.
Adb doesn't work
And it doesn't made a change for me if I flash a OS that is right or if I flash a OS that is wrong.
It does the same with both so I can't see how I should ever revive it.
Mabye a custom recovery packed into the OS file but idk how and where to get one.
