Does Windows recognize the phone while in download mode, and have you already installed the latest LGUnitedMobileDriver?...

[Q] Need help getting into recovery

I flashed something that was incompatible with my version of android and my phone is stuck in a boot loop, aside from that my power button is broken so I cannot simply press volume down and power to get into recovery. When I use the command "adb devices" on my computer while on the boot screen my phone comes up but says it's unauthorized. I can get into download mode though. Do I have any options besides re-installing android altogether from download mode?

Download KDZ and use normal mode to flash it
It should overwrite all partitions except /data and your phone will still retain its data

How did you damage your power button mate? DAMN !!! That's horrible! Send the phone in for repairs! You can't really operate the phone with a broken power button.. Try this link to get your device working again.. I'm afraid that you need to download the appropriate KDZ file for your device and use the LG Flash tool to restore your device.. Good luck!!:fingers-crossed:

What did you flash, what error does it display, is it "secure boot error", which version of g3 do you have, can you access recovery, do you have TWRP...?

i used ioroot to root the g3 (D855), and i flash with twrp-2.8.0.0_d855-signed.img. Yes i believe it was the secure boot error. After that the notifications lights at the topped flashed blue and red i turn the device ofd to restart and it will not turn on i have tried both to get into the recovery menu (power+vol down) and download menu (power+vol up) neither of which is working.

Ok... Lets start with battery pull in and out.
Even if you do recive secure boot error for booting to the unbumped recovery you should be able to boot to the OS, try with that.
If this fails, do the battery pull again and lets try to get you to the download mode. The way you specified (power+vol down) is incorrect I belive. What you need to do is hold the volume button WITHOUT the power button which will be followed by connecting the device to the PC with installed LG drivers.
If that works you could flash stock files, follow the thread: http://forum.xda-developers.com/showthread.php?t=2785089
Check in device manager how is the phone detected what mode ...

Does it get into download mode? For this one get the battery out and wait 2 secs. Plug it back in. Be sure to have an USB Cable ready plugged in the back of the PC (NOT IN FRONT HUB and be sure to be the original Cable). Hold Volume UP and Plug the cable. Keep holding Volume UP until you see download. Tell me if you see the Firmware Update screen or it is a security error.

Your boot loader is broken. Gonna have to get to the down load mode and reinstall either the or the stock. You can probably flash the recovery with .IMG file with lg flashing tool. Nerdy blond's twrp is one of those files that you can use. You can even try installing it first with the adb shell command, you can get the instructions at the same place where you download.

Thank you for replying.
I cannot do anythings since I cannot enter into download mode.
I pressed volume key + and - and insert the usb cable to computer. There is nothing happened, computer dose not show the devices attached and the phone stay in the LG logo screen.
Also, I cannot use adb commands to force the phone enters into download mode as it shows nothings under "List of devices".
Is there any methods I can go into the download mode???
Thank you!

If your phone shows LG start screen, it should go into Download mode. I had similar problem few days ago while I was testing some kernel patches, it just froze on the LG screen. Solution was to unplug it, remove it's battery, SIM & SD (you don't have to remove SIM & SD, I just work that way) , make sure it's off, return battery back, press Vol + & Vol - at the same time and plug-in the USB cable.
Before that, make sure you have installed LG Unified driver (can be obtained via LG's software from support site), because without that Windows won't recognise your device.
After that, once you make your phone usable with Freegee/whatever you use to install initial recovery, flash official TWRP, because others are too old - that Philz CWM is old but still working with Lollipop but not work good and is tends to lock itself into a bootloop if you use hardware keys to enter; that other one, from GPRO_recovery APK is not supported and not working well (for me since day one), so it should be replaced as soon as possible.
Also, I can suggest you to flash your phone from stock 4.1 (not KitKat), root, flash recovery via freegee and after reboot update to latest official TWRP via Flashify.

Thank you for your detail reply.
I have tried to reinstall the LG driver and try to enter download mode again.
The screen is still stuck on LG logo and I cannot find the device in hardware manager (cannot recognize it).
I cannot do anythings until it can recognize it.
(Is it the bootloader is broken? and can I fix it?)
Thank you very much and waiting for your reply soon.:good:

Which version of Windows are you using? It should be displayed under Serial ports in Device manager (named something like LGE Serial device) and LGFlashTool should recognise it immediately. I can't make you a screenshot/check for real name because I'm running Linux right now and can't reboot.
Also, try with another cable/port, remove all other android drivers you may have (Samsung's, Google's...) and disable antivirus.

OK, it doesn't enter download mode. So, step by step:
- remove battery and leave it for 15-30 seconds, return battery
- press Vol+ and Vol- at the same time and keep them pressed,
- plug USB cable in while keys are pressed
It should immediately put you into download mode, with no LG screen, just black screen with gray box and red text I've described to you.

So, whatever you try to do, phone just shows LG logo, not even a message in an upper left corner?
I'm running out of ideas. I have exact same variant (E988) but only time it didn't want to enter download mode this way was when cable I was using was broken...

I have changed the cable, but it is the same.

Download Mode bricked.

I tried the method to enter the fastboot screen, but now the phone does not turn on, pops singer continued error 1003. I wanted to install stock rom download mode but I do not turn and do not know what to do now. Help.

Soft Bricked Fix needed (stuck on app optimisation)

Hi guys,
my wiley fox swift gets stuck in a continual optimising apps cycle. I can't enter recovery mode, when i press power+volume up it enters fastboot
(only see the black fastboot screen can't do anything). I did not change anything on my phone (not rooted) it worked fine yesterday and today i can't get it to work.
It's always optimising apps, if it's finished then i see the cyanogen logo and it starts optimising again shortly after.
I removed the battery and did wait about 15 minutes before putting it back in, i tried waiting (after 2 hours+ of it optimising i gave up),
i does not get recognised when i connect it to the pc (although i only used it to put stuff on the sd-card before) maybe a driver would fix this but i'm not sure which one.
I'm pretty clueless right now and i would be happy if someone can help me.
Saw the same thing on a friend's device today, used fastboot to factory reset the device. Insert USB in a powered-off device while holding vol+ then using fastboot do a "fastboot -w" to factory reset and recreate the (probably corrupted) data partitions.
i installed the minimal adb and fastboot connected my phone with my pc started it and tried it.
it doesn't recognize my phone and is stuck "waiting for any devices".
what can i do now? i'm not very experienced with android phones and fastboot.

ADB needs debugging to be enabled in developer options
FASTBOOT will only work if the phone is in bootloader mode
I already said in my first post:

since i never changed anything in my phone I haven't enabled debugging in developer options, if I could access the bootloader mode I could reset my phone but like i said,
it enters fastboot and not the bootloader from which i could enter recovery mode
under these circumstances, can i do anything?
see here https://wiki.lineageos.org/devices/crackling/
Note they call bootloader mode Download
Ok i can access recovery mode now (it was explained wrong here)
i tried to factory reset but the problem still persits.
in recovery mode i did go to ->Wipe data/factory reset then i had the options (No/No/Yes -- delete all User data/No)
i choose the third option and it did load a short while. after a reboot it still wants to optimise apps.
what's the best option now? i can choose (Apply update\ Wipe data/factory reset\Wipe cache partition\wipe media\reboot to bootloader\View recovery logs)
Fix
Hi,
I had the same issue and wrote the Wileyfox customer support.
They provided me the following instructions to fix the issue:
Download:
* 1 - ZNH0EAS2NH
* 2 - ZNH2KAS7EB
* 3 - TOS111B
Repeat for File X in [1, 2,3] :
* Goto Recovery
* Update your phone using File X
Since this is my first post I am not allowed to post links.
Find the full document including file links here: h t t p s : / / we . tl / B1IpUP6wtB
Already after running the first update my phone booted again.
Only thing I noticed is that the UI feels a little laggy / slower than before.
Regards
