Help!!! Can't boot into recovery

Help, i installed the twrp recovery and went about installing a rom but when i went to wipe the phone i wiped everything. So now when i try to boot into recovery it just shows the lg logo with the l.e.d cycling. No idea what to do please help.

Can you get into download mode, If so you can flash the stock .kdz for your device with the lg flash tool and you will a stock functioning phone agin. Then you can root and install TWRP again if you would like just like you did the first time. But make SURE that you use CORRECT kdz for your device model remove the batteries and under you should she something like this eith the X being numbers or letters: LG-XXXXX find the .kdz for the XXXXX value and flash it with the lg flash tool

Thanks alot, its working but its taking its time still only at 14%

Your welcome if you still need help just ask

G3 boots into firmware update only
I recently updated my lg G3 ( Google patch update named Aug-18-2015 etc) and it started to malfunction with resets, crashing and eventually got it stuck in boot loop. Then it booted into a green screen that said "demigod crash handler/tz crash" thrice. Instead of a hard reset I decided to using the lg mobile support tool to fix it. During the upgrade recovery my phone went into download mode/firmware update. I could see the progress bar moving and then get stuck and my mobile would switch off. Took out the battery, disconnected and reconnected the phone and tried the process all over again but in vain. I repeated this at least 8 times and eventually gave up. Now my phone is basically useless and only boots into firmware update. Hard reset doesn't work either. Can somebody please help me fix this?
Android version : 5.0
Kernel: 3.4.0
Firmware : v20t-ame-xx

[Q] Bricked Phone ?

Hi, i don't know what happened. I had CM 12 installed but then wanted to try Miui v6 so i downloaded it and flashed it but accidentally uninstalled gapps and WilKernel so the phone kept booting back to recovery without being able to flash any roms. So i followed this thread that told me to flash TWRP 2.6 and that it worked with any recovery ( I had 2.8 ) and now there's nothing that happens. I turn on my phone and and it stays on the LG logo. Can't get into download mode or anything and i'm scared to death right now since this is not my phone. Someone please help me !!

Are you sure you can't get into download mode? Have you tried pulling out the battery and wait for a while before trying again?

I actually unbricked it with LG flash tool, the only problem now is that it's stuck on JB..

Help!! Android One Hard bricked, Unable to start the phone

15 days ago I migrated from android M to Android L cos fast battery draining, I flashed Android L stock rom using SP flash tool v5.1424.00. and everything worked fine till yesterday, my phone started crashing some apps so i restored it and my phone stuck in boot loop again (why again? cos before i got bootloop 4 month ago, that time i get rid of by flashing Android L stock rom "thanks to xda-developers members:good:")
so after restore my phone stuck in bootloop, so just like last time i did all steps to flash stock rom and it downloaded successsfully but bootloop not resolved. i did it again and again.:crying:
after that I used format all + download in SP flash tool (I think that big mistake I did) and after that Android One has full bricked, phone is not booting or not able to go to recovery mode or fastboot.:crying::crying:
not working anything pressing power button or Power+Volume but my pc detecting in device manager. I am able to flash in "download only" mode So I tried to flash stock ROM using SP Flash Tool and it downloaded successfully. But still not booting.
one more when i tried "firmware upgrade" in SP flash tool i got error "failed to get pmt info"
at last my device is bricked please please help me to unbrick it
Thanks in Advance

Canvas A1 - Sprout 4 Hardbricked.SP Flashtool won't work.

My Canvas A1 isn't booting at all (nothing happens when power button is pressed),My phone has been unstable for quite some time now.Initially, I installed MIUI 8 and it crashed after one month or so.Then I installed Stock MM optimized version from XDA and it went well for sometime.Then after a month's period even stock OS crashed.Rebooted and stuck at bootloop.
After that I tried reinstalling the same OS but it always stuck at bootloop.
Hence,I went with SP Flashtool.Tried flashing (Download Only option) Official Lollipop FlashFile available here on XDA,it did flash successfully but phone wouldn't boot.
Next,tried All Format+Download option and again it flashed successfully but now nothing happens not even micromax logo shows up.Hence,I believe I have hard bricked my phone have tried every option that I could think of but to no avail.
I need expert advice on this hence posting it now.
Please Help.
Thanking in advance.

Unbricked my phone but now I'm stuck with the chinese firmware [BND-L21]

Hello,
I received my phone two weeks ago (BND-L21 version) and Friday I tried to manually update it to Oreo (with this topic : https://forum.xda-developers.com/honor-7x/how-to/manual-update-to-oreo-beta-emui-8-bnd-t3767044). I don't know what I did wrong but it didn't work (my phone didn't reboot on the stock recovery, only on TWRP). After a few try, my phone wasn't booting anymore, it was stuck on the orange message about the unlocked bootlader and the message "Your device is booting...".
I managed to get it back working with this topic : https://forum.xda-developers.com/honor-7x/development/firmware-updates-link-flash-risk-t3723810. The problem now is that I'm stuck with the chinese firmware (i don't have the Honor animation when my system is booting, I now have an Android logo on a black background). I don't have any Gapps installed and I can't flash anything with TWRP. When I try to flash SuperSU, i have an error extracting ramdisk failure and something with the boot.img.
Now the model of my phone is a generic_a15 and I don't know how to get back on track.
I'm a little bit desperate now, I don't know how to install another firmware. I tried to install this custom rom : https://forum.xda-developers.com/honor-7x/development/openkirin-aosp-8-0-honor-7x-t3746257 but I was stuck on the orange message again.
If anybody knows how to solve my problems, I'll be grateful
Thanks !
[UPDATE] I don't know if someone is reading but now my phone doesn't boot anymore and FRP is locked ?

Call Huawei customer support and get a ticket started to send your phone to the nearest repair center. Best of luck!
