Sprint G3 (LS990) Bootloop - G3 Q&A, Help & Troubleshooting

Trying to recover files for a friend who doesn't understand the meaning of the word "backup." Phone bootloops, but I can get into download mode fine, and I can get LG Flash Tool to recognize it. (I think; it's hard to be certain without actually doing the wipe, but I went through all the insructions to setup COM41 and everything looks good so far).
I'm used to working with Samsung phones, and I know my way around TWRP and adb, but I can't find a way to get TWRP on this... the only methods I see involve either sideloading an apk or pushing an image file, neither of which is an option right now.
I can't get into recovery mode at all; if I pull the battery, then put it back in, hold POWER + VOL DOWN, release when I see the LG logo, press them both immediately again (also tried just letting go of power and then pressing it again), it tries to boot normally and eventually bootloops.
Is there anything left to try? Any sort of non-destructive way to reflash the OS? Any way to load TWRP from download mode?

[Q] Can't boot to recovery

I have a F400K G3 (Korean Olleh). It's rooted and bumped. I flashed the bumped TWRP image via Flashify and rebooted recovery via Flashify. It works. But when I try boot to recovery from a complete shutdown. It just boots into safe mode. I did exactly what was stated in the Bump thread (Power+V. Down, when logo appears, release then press again quickly) and also tried substituting V. Down button with V. Up, but it still wont boot to recovery. It just keeps going into safe mode. The video provided in the thread was using an AT&T model so maybe it differs from every variant. I want to know if I'm doing something wrong or the instructions are wrong.
Thank you.
You tried without releasing? Just keep holding buttons

I have tried it as well without releasing. Does the same thing. And it never shows the reset screen. It just goes directly to the boot animation. Rebooting from Flashify also doesn't show the reset screen but it does get to TWRP. But I need to boot it from complete shutdown because I'm gonna test a Flashable zip ROM without root so rebooting using Flashify would be impossible.
Bump.
Seriously. Anyone?
I am subscribing because I have the exact same problem. I have tried every key combination I could find for the G2 and G3 but no luck...
This is exactly the kind of problems you get when using stuff like Flashify. The holding of the buttons etc you mentioned should work. Are you sure you aren't connected using a micro usb?

No, I am not connected to USB. If I reflash the recovery using ADB will it work? But I do have some worries because I'm using KitKat bootloader on a Lollipop Stock-based ROM (here) and I think I may get some errors.
It's not very important right now because I have root now and can reboot to recovery using Flashify.
I think all korean models cant enter recovery via hardware keys, mine is F400L and have the same problem.

Turn off the phone completely. Press and hold Power and Volume Down. When the LG logo appears, release. After a split second, press volume down and volume up. White screen asking you to reset will appear. Press Yes two times using Volume buttons.
UP!!!
Any remedies? I justed from stock to cm12 LG g3 F400L..
Cant go to recovery mode. Cant flash anything..
Same prob,always going to safemode.f400k rooted,cloudy2.5
i've Lg g3 F4ooL and using Resrruction remic 5.5.5
I stuck in a Bootloop and my device is also not booting into Recovery or safe Mode.
Lg flash Tool is also not Connecting to my device in Downloadmode.
I think There is NO solution At ALl
Has anyone solved this issue?
to get in recovery on F460s, worked on mine, Press Vol-up + Power, as the logo appears release the keys and press Vol-up + Vol-down, you will boot into recovery.
I have the same issue, cant go into recovery using hard buttons on F400K. Any one able to succeed in this?
Same issue on LG G3 F460S, no combination of power + volume buttons + releasing them and pressing again when LG logo appears works. The device go straight into booting system and gets stuck. Is there any other method - maybe short-circuit some pins on the motherboard, to boot into recovery or do a system reset? Please...
OK, turns out that the combination is different for Korean models of G3, as misbah711 wrote, volume UP + power, when logo appears, release and press both volume UP + volume DOWN. If that does not work, try again, but release only the POWER button and press immediately volume DOWN (while volume UP was held all the time). Also, I first tried it without the back cover, as I have to remove battery to turn it off, did not work. Then with the cover it did, not sure if it's an important detail or not.
However it's not the end of the story for me. An image with Korean text appears, and nothing. No combination of power and volume buttons pressing does anything. I'm attaching the image. Also tried a web service to do Korean OCR and then used Google Translate - does not make any sense. Could anyone advise how to proceed and do a factory reset on this device? It won't boot into the system (gets stuck), no adb or any other communication with it.
Edit:
Turns out that when the Korean text appears and I connect USB cable to my PC, adb works correctly. Typed:
adb reboot recovery
The phone rebooted into recovery and now I'm doing a factory reset on it. Looks like all will be fine.
i have d851 on stock kitkat. I flashed TWRP and Philz but no way i can get into recovery mode. it always goes to fastboot mode no matter how I reboot into recovery. Now i am looking for stock recovery image. or a way to fix the twrp/philz. ROM boots just fine.

[Q] F180 (vol up + power) does't work

Main information. F180, bootloader unlocked with teenybin, I'm on resurection lp rom.
Everything worked fine but I accidentally flashed the wrong file, now the phone is in boot loop. Though that is not the problem (I know how to fix it).
The problem is that there is no way I can access recovery. This happened to me before but I got lucky - computer detected the phone while it was in bootloop and I was able to use (adb reboot recovery). Next time I got lucky some kind of green screen showed up and from there I was able to go to recovery. Now i know that the most obvious way to go to recovery is through bootloader (vol up + power) but no matter how many times and in what diffrerent ways I try it I can't boot into bootloader it simply starts booting the rom... I am frustrated and have zero ides. Maybe you have some. Thank you in advance.
P.s.: i held down the power button for over 1 minute before attempting. And also download mode works.
If you can still boot into download mode you can try to flash the original firmware with the LG flash tool:http://forum.xda-developers.com/showthread.php?t=2797190
Don't worry you can use it for the LG Optimus G too:fingers-crossed:
Thank you for the idea, but I managed to solve my problem the same way as before. Use adb while the phone is in bootloop.

Stock + Root - Lenovo A390T

TLDR: Need a stock image, root and custom recovery for the Lenovo A390T
Hi All,
So my Chinese friend brought me her mothers phone to try and fix. As far as I can gather, she tried to update, got impatient and rebooted it. It just permanently hangs on an "Updating..." screen. First thing I tried was getting into fastboot, I managed to get in and it said "Fastboot Mode" in the top left corner. My PC doesn't recognise the phone as connected (even though if I turn it on normally it does recognise ADB - ruling out any issues with drivers or my hardware I think?)
I also tried to boot into recovery. I get the little droid with the exclamation mark, but that's it. If I press the power button I see the menu for maybe a second as it thinks I have clicked on the first option (Reboot) - the up and down buttons do nothing (pressing or holding) so literally the only button I can press is power, which just reboots the damn thing.
The good news is I did manage to boot Android into safe mode, then tried a factory reset from there. It booted back up without a home screen app but everything else seemed okay. I could get into settings from the notification menu by pulling the top bar down, but otherwise it was just black with a top bar.
I downloaded an APK for Nova and installed that through ADB, and we're golden on the actual phone working again. What I would like to do is install a custom recovery in case it ever happens again, so I can easily recover the OS - and get a stock image. I did find this for root, but it doesn't seem to work (Framaroot says there are no exploits available) http://forum.xda-developers.com/showpost.php?p=50774585&postcount=7
So I need to root, install a custom recovery, and then get a clean stock image back on the device, any ideas?

No hardware buttons work!!

Hi
Could some one tell me why i cant get in recovery or factory mode with hardware buttons, i am on stock 10d with twrp recovery installed and rooted wirh super su through twrp. I installed twrp through adb with normal command and device works just fine through reboot apps from os, boots in recovery,fastboot etc just fine,same through adb commands.
But there's no hardware combo or anyrhing working when trying to enter recovery or factory reset working at all?
Tryied every combo i could find saying how to from internet.
It just boot up in os as usual.
And phone dosen't reset while holding power button for 10s + either
It's a bit scary because bootloop is going to come eventually for sure and then there's no rescuing avalible
Could someone plz tell me whats going on?
Im new to g4 so, some help would be nice.
Thanks in advace
It's a bit tricky, to be honest.
• Power off your phone
• Hold "Volume-Down" and keep your "Power-Button" pressed. So you should keep both pressed, until the 1st LG logo appears
• Now just leave the "Power-Button" for ~1 second whilst kept the "Volume-Down" button still pressed, press now the "Power-Button" again and keep holding it
You're now forced to deal with the standard-ui from LG. Go to "Yes" and again "Yes". TWRP now boots and you should be fine .
Edit: Just my tiny story... I watched several videos and also had a nasty bootloop. I was afraid, I now bricked my phone. But a nice user showed me this way and this was the only way, I got my phone recovered.

H815 Soft bricked(?) adb shows device offline

Soo.... I messed up and edited the build.prop specificly the ro.build.type property. I tried to enable some debug options without validating if this would be a good idea (hint: it's not).
It seems that this has bricked my phone, the first LG splash screen shows up with the powered by android, and the second animation just keeps loading forever (making the phone very hot). And the LED flashes blue continously.
I did manage to get the device visible in ADB but it tells me that the device is offline so I can't do anything with it.
Tried booting in recovery mode (holding power button + volume down) but it just own't go into recovery mode.
Some extra info of what runs on my phone:
- version H815
- Android 6.0
- bootloader unlocked
- TWRP installed
- Rooted
- XPosed installed
Any idea on what I could try to fix it? (I guess stuck with a brick but oh well).
Thanks!
What do you mean, by it can't go into recovery mode?
Nothing is showing on screen?
Go to downlod mode either use lgup or lg flashtool to reflash the firmware that you are on... Do u remember which firmware you were on ?
Thanks for the replies!

I meant that it just boots 'normally' when I press those buttons, it shows me the first LG logo and the second animation just hangs, whatever I do. I tried all sorts of combinations with the power button + volume down. (Keeping it pressed, briefly letting it go after the lg logo and repressing them).

I don't know exactly which firmware I was on but I can't even get my phone into download mode (same as my other response, pressing volume up doesn't do anything).
The recovery and download mode used to work but I have no idea why it doesn't now...
When booting the phone, hold the power button and volume down button simultaneously, when LG logo appear, push the power button again. You should see the white screen, where you choose "YES" twice. Then the phone should kick you into TWRP or different recovery mode.
But how the hell editing build.prop can mess with recovery and download mode? Sounds incredible

Maybe he has bootloop issue... ILAPO
Yeah I have no idea why the buttons aren't working for me. After a lot of searching I found this thread:
http://forum.xda-developers.com/g4/help/soft-bricked-device-t3248144
Which is basicly the same thing I'm experiencing, ADB comes online for just a brief second (kept spamming the reboot recovery command) and got in TWRP and I just flashed another which worked fine.
Odd thing is, even now my phone works I can't start recovery or download with the hardware buttons...... oh well, thankfully adb works as it's supposed to.
Thank you all for your help!
