[Q] LG G2 bootloop, No recovery mode, only download mode

Hi guys, (LG G2, Rooted, had twrp but now its vanished?!)
I managed to get my LG G2 into a bootloop. I was replacing bootanimations and rebooting and testing them out. I finally tried this 1080p boot animation that looked sweet. Once the device rebooted it would show half the boot animation and then reboot. I had twrp installed but now every time i try to access it it just ignores the hotkeys as if it doesn't exist anymore. I can only get into download mode if a usb is plugged in.
All i need to do is flash TWRP again so i can flash the stock bootanimation back. I do not want to do a fresh install as I have many important files (i know i should have backed them up). I have tried to access my phone via adb using windows commandline tool whilst in download mode. however, adb doesn't find my device (I was going to attempt to push the stock animation back).
Please help me guys i need my phone to be working by monday as i have work! thanks in advance

1. If you connect your phone to PC, what happens?
2. I also had trouble accessing TWRP, so I did the "Factory reset" button combo (Don't remember what it was) and when I slided to confirm, twrp booted. From there I think you have adb and can fix everything.

To get to TWRP, hold the power button until the phone turns completely off, then turn on the phone while holding the power and volume down buttons, then when the LG logo pops up, let go and re-press those buttons. When prompted for a factory reset, press the power button. Works every time for me.

Alone i used lg flashtoolnow,its ok. I didnt click factory reset i assumed it would delete everything? With lgflash i have restored system and everything is how i left it.

First off, you'll need to make sure your phone isn't plugged in or it won't work - I'm afraid if you can't enter recovery you'll have to go back to stock. http://forum.xda-developers.com/showthread.php?t=2432476

Try to flash the Kitkat baseband or if you are fully stock then i suggest you to flash the KDZ to go back to full stock(http://forum.xda-developers.com/showthread.php?t=2432476)
If you still have important data like pictures or what then do normal flash. Use the Android version you also had as stock and use that as KDZ. If you are not stock then can you reach TWRP?
and what did you do before that causes the black screen?

Stuck with the LG logo. Nothing happens in download mode
Hi All, not sure if this has been answered prior. This is what happen, I wanted to flash SOKP so I backup my phone and saved to PC using Titanium. I have TWRP installed.
Boot Into Recovery Mode and Wipe Data,System,Cache,Dalvik
I restart so I can flash the SOKP Rom and all I see on my phone is the LG logo. I try to restart using the Power and Up button, but it just sits in the download mode saying "Firmware Update" with no movement or action.
The phone is unable to turn off now. This is my first go at Flashing a Rom. Any help or suggestion would be greatly appreciated. Thanks in advance

Hey, I have the nearly same problem with my G2 running CM12 also installed recovery
But I can't reboot in recovery neither with the factory reset buttons, nor manually with SDK Manager, because the device is not found.
So I can just reboot and it shows the CM boot image, or get in the download mode.:crying:
Any suggestions?:fingers-crossed:

I have boot loop, only download mode accessible, device not found on adb. When I try LG FlashTool, instead of using the KDZ file I provide, it starts downloading some other firmware at times, and at times it says your software is up to date. What do I do? :|

I tried this and it just wont reset. If i hold down VOL MINUS+POWER+MENU the bottom LEDS blink with nothing on the screen.

it sometimes fails just keep trying..power off completely and wait for a minute then press Key combination
volume"-" &
home button +
power button until it vibrates and show LG logo...here if you do not release power button (quick) then only LEDS BLINKS so on vibrate and when screen get on then release only power button and keep pressing both of the others for about 8 seconds then release volume only

[Q] i9500 Bootloop Can't Go Into Recovery or Download Mode

So my phone is bootlooping whenever my battery is attached. I can't go into recovery mode nor download mode. I try to push the combo buttons and the yellow triangle comes up. But when I push the vol up button it didn't load to download mode and keep rebooting. Help?
This happened after i flashed the new 5.0.1 Lollipop OS and try to put CWM recovery.

Zuk Z1 Soft Brick

Dear XDA friends,
i always hoped not to be one of those guys, who f****d up their phones to the point of no return. I really screwed up this time. Well, here I'am writing you about my screw up.
I unlocked, rooted, flashed and repaired all kinds of android phones in the past years, never without problems, but I could always fix it somehow. Not so much this time.
Now I'm stuck at Bootscreen with the Zuk logo. I even have problems pinging the phone via ADB.
Sorry for my noobish question guys. Any help would be much appreciated.

I got this translated from a chinese website:
For fastboot mode:
The phone turned off; keep the connection turned off the data cable to the computer, press: [volume down key] [Power Key] waiting to enter the fastboot mode.
For recovery:
Turn off the device
Press and hold Power key
When vibrates Volume UP key + Volume Down key about 10 seconds
Release all key when Android logo appear then you will see Android System Recovery
Use Volume key to select Menu
Use Power key to Confirm
Can you enter any of these 2 modes?

Does anyone know where can i find the scatter file , MTK ROM for zuk z1, i would like to try the SP flasher tool. Or if anyone have any idea how to solve this issue on lenovo zuk z1,pls. help.tnx

Can y get to fastboot ?

im facing the same problem after i had the stupid idea to lock the bootloader again, before that i flashed the phone successfully with the cm mod recovery and cm 13.
Has anyone found a solution to this ? or do i have to send it back ?
What i did exactly :
I locked the bootloader again and just to test it i tried flashing the recovery again , ofcourse it didn't work which was what i wanted.
Afterwards i rebootet the bootloader with sudo fastboot -i 0x2b4c reboot
now im stuck in a bootloop that i cant even stop , in other words i cant turn my phone off nor can i access the recovery or fastboot
Im feeling so stupid that i locked it again .... i will try to get into recovery after my phone ran out of battery but so far it looks quite bad...does anyone know if i will get a replacement even though it was my fault ? ( i don't need to say that it was my fault ..and the bootloader is now locked again )
UPDATE::
I found a promising thread about this problem, i will report back here if i was successful.

Please help , same problem
I am facing same issue too from 2 days. I didnt even try to flash custom roms or play with boot loader or recovery or anything. All of a sudden my phone entered boot loop. After two three bootloops phone is entering "12 apps optimized of 230 apps" mode, completing optimizing all apps and then failing to start apps, entering boot loop again.
Effort made so far to fix -
1) Went to recovery and cleared cache - didnt work
2) Went to recovery and did factory reset - factory reset did happen but boot loop didnt stop, I realized that factory reset happened because now its saying optimizing 120 apps instead of my 230 apps during the bootloop.
3) Went to recovery, Entered fast boot mode but not able to connect to PC. Fastboot devices is not showing anything. I made sure proper driver is installed after researching on XDA.
4) Went to recovery, Tried "Install update". Didnt install anything but browsed through folder structure and realized my data is intact
It will be great if someone can help me atleast recover my data before I handover phone to service center for fixing boot loop issue.

Sorry For Re-posting Here. This is Solution
Why this is happening ?
Due to Dirty Flash from Zui or from COS/CMOD but suddenly Bootloader gets locked
May be Due to Some Custom Rom which only works with Old Bootloader ( And you are on latest 2.5 Zui QPST Flash)
Reasons are many. I also did same mistake. I flashed ZUI 2.5 using QPST then unlock bootloader using official site installed twrp after wiping cache system and data , Installed Lineage 0S JAN Build then without rebooting installed Lineage Nightly build (Latest) with Gapps After rebooting Phone goes into Restart endless loop on ZUK Logo. Blink and Vibrate .. After 1hr I figured it out but its 5am So slept.
HOW TO FIX ENDLESS REBOOT ON ZUK Logo ?
-> Identity vibrate patterns (Press Power Key I count 6- 7 Vibration pattern ) After long Vibrate immediately remove finger from power key.
->Once its Done (Phone completely off)
Download QPST and Official COS QPST from this Link https://goo.gl/InWQji OR https://goo.gl/iqrnlI (I am personally Very Thankful to D tech Terminal for posting Wonderful video on Youtube https://www.youtube.com/watch?v=4Dl6JkAVpuM
<- please install all drivers and software.->) @ankurpandeyvns Thanks bro.
Main Task is here and Lots of Patience is required and You also need to be very Blazing fast to achieve this.
-Once you download and install Qpst open Qfil
-Now press Volume Up only and connect USB (Just press POWER KEY only for 1 sec It will vibrate and connect)
-Without waiting hit Download button.
-Voila It will start flashing your phone again and Hence Your phone is now Revive..
-Once Revive You can use it to again flash custom Rom or stick to stock Rom if you want.
Keep Flashing !!!
Patience is Key here. And Don't lose hope.
:good:
EDITED:
While connecting to pc and by pressing Volume key you also need to press Power key for 1 sec or 2 sec until it gets detected. Thanks addicted777 (for tip)

Turn off the phone. Plug the PC end of the USB cable in the PC. Press and hold volume up and plug in the USB cable in the phone. Hold it like that. After a couple of seconds, you should be in download mode. Then use LG Flashtool/LGUP to flash Lolipop/Marshmallow.

now stuck on logo

There's no custom roms for Qualcomm Spirit. At least not yet.
