[Q] I have problems with updating lollipop 5.0 in my Nexus 4.

So, my phone was stuck in No Command bootloop. I’ve done the power+volume up and had cleared cache and even done a factory reset. Those did nothing and my phone is still in stuck No Command loop. I think I’ve made it even worse by trying to Flash Recovery and Reboot options in the Nexus Tool Kit because my phone won’t even get to the No Command screen. It just turns on and turns off after Google comes on. Currently it stuck in that loop and only stops once the battery is completely drained. Also i have tried using power + volume up and it doesn't help . Please help

As you've upgraded to lollipop ?? You came from a custom rom ?? Enters the bootloader?

with wugfresh nexus root toolkit click on the button "soft-bricked"(flash stock + unroot) or something like that to restore the phone. After that try another time to unlock and root with a custom recovery (for example twrp).
When nexus root toolkit installing the original lollipop rom, look the "dos window" to see if the software shows errors, because sometimes the process ends without a real restore.
If you have other problems, please post a screenshot.

LG Logo Bootloop - Can't access TWRP - No DL Mode

Hi guys,
New to flashing custom ROMS. Good news - flashed CM12, then LiquidSmooth and I'm learning a lot after having soft bricked my phone a few times. Bad news - After trying to get back to Stock I'm not able to get out of this LG Logo bootloop. The LG logo will flash, screen will go black and the whole process starts again. It doesn’t progress past that. I'm unable to get to TWRP recovery or download mode.
My idiotic move:
Iffy stability with camera and mobile data with CM and LiquidSmooth. Decided to go back to Stock.
I flashed my nandroid backup, which I believe led to a bootloop (can’t remember). Was able to boot to TWRP and get back to CM12. Then I had the genius idea of using AutoREC and selecting the “Go Back to Stock” option. Yes, it’s already sounding like a bad, and nonsensical idea as I say it now. Can't remember exactly what I did next - I either flashed my nandroid backup or did a factory reset through CM settings. Threw me into this bootloop.
The details:
Model - D800 - Am sure of this.
Stock software before flashing CM12 was Lollipop 5.0.2 via OTA.
TWRP Recovery 2.8x something or other. Used AutoRec to flash.
I can interrupt the bootloop and access Factory Hard Reset through Power + Volume Down
Had to go to JB Bootloader in order to Flash ROMs. Errors returned otherwise.
Roadblocks:
No download mode. Holding Volume Up & Inserting USB cable doesn't work. Although am able to get bootloop to include a blank screen with red flashing LED through this method from time to time.
Phone boots up, and goes directly into bootloop when plugging USB cable into phone. This happens both when plugging into a wall charger or into a computer. I think this is probably the biggest pain and is holding up things from progressing. Can turn off phone by holding down power for a few seconds, BUT if the phone is plugged in it will continue to boot on its own.
Phone not recognized by computer & ADB However, was at times able to get Device Manager to recognize the phone as an "Unknown Device" after going to the Factory Hard Reset screen. This is no longer working after trying different drivers. I’ve went through LG Mobile Universal Driver as well as the Koush driver.
Going through Factory Hard Reset via hardware buttons only throws phone back into BootLoop
Can’t boot into TWRP
Any insight or help guys? Thanks in advance. I think getting into Download Mode will be a quiet victory. I’d like to try to use Supersports guide once I get there to go back to stock.

[Completed] Verizon LGG3 VS985 not booting

Hello
I am new to working on these phones so I apologize in advance if I don't properly state any processes or terms correctly.
I have a stock non modded Verizon LGG3 VS985 that experienced problems with WiFi and Bluetooth not working and significant battery drain. This happened right after a recent update to marshmallow. I tried cache clearing, safe mode, hard reset and nothing solved the problem. I decided I wanted to take the phone back to factory condition. I started with the LG flash tool that uses the .tot and a .dll. I ran the flash and when the program got to approx. 80%(at checking mini os phase of the flash) the phone began to reboot and only got as far as the LG logo and after about 2 min of the phone trying to reboot the flash program said fail, usb connect or something like that. At this point the phone will only start and go into a loop that includes the vibrate and the LG logo. and that will cycle until I believe the battery would die if allowed. I then found a link here at XDA (https://forum.xda-developers.com/verizon-lg-g3/general/guide-flash-to-stock-10b-kdz-method-t2928140) that uses the KDZ method, was well written and easy to follow. I ran it on the phone and it was going great. The flash program got to 88% and the phone went into the boot loop with the vib and LG logo . The flash program continued to run until it was complete while the phone was in the boot loop and it got to 100% and said that the software installed. I powered down the phone via battery removal and now when it tries to boot it vibes, shows the lg log and then the green android symbol shows for about 2 seconds and then it does it all over again. I have tried a hard reset and nothing changes. I appreciate any ideas any of you may have on what I can try to get this resolved. Thank you.

No longer able to boot into recovery mode after flashing LineageOS

Hi all, have a rooted OPO that was running ExodusOS. I decided to try a flash of Lineage and so booted into recovery, backed everything up, flashed it. Everything seemed to go okay but after the boot logo the screen just goes black and stays that way until it gets shut back off. I went back to TWRP, loaded my backup and all seemed well as I was still able to use my old backup just as normal. Well, I tried reflashing Lineage from TWRP again and I still get the same black screen issue. This time, however, the phone will neither boot into Fastboot nor into recovery mode and just goes straight into loading Lineage. Because of this I am left with a soft brick until I can get this straightened out. I tried connecting the phone to my PC but it is not detected as a device. I only need to boot into my backup one more time so that I can back everything up, so even if it's only a temporary fix, I'm okay with that too. Any suggestions?

Sounds like a Hardware issue? Sorry to say what your saying doesn't add up and or make sense. Fastboot should work no matter what even if you soft brick it and mess up recovery. I suggest letting the power fully drain maybe and google how to fast boot in case you are doing it wrong.

I've tried that but it can't find the phone. The phone gets detected as a new device in windows as evident from the device connection sound but it also never shows up in the list of devices from My Computer.

I agree with what @Shinobi_warrior said.Seems like you just have a soft brick,so you should be able to boot into fastboot mode without any issues.Are you sure you're doing it the right way? Did you try draining battery completely and then booting into fastboot(yes,you don't need much battery to boot into fastboot mode)?

Well I was finally able to get the device detected by ADB, but it just shows as offline. I attempted to use the repair kit and nothing seemed to happen. I also attempted a different tool (https://forum.xda-developers.com/on.../oneplus-one-toolkit-manudroid19-gui-t2807418) and then booting into either fastboot or recovery that way, a terminal window pops up and quickly disappears, and then nothing else happens. I still see the TugaPower boot logo and it still goes to the blank black screen after this.

Need help on bricked and boot-loop LG V50 Thinq KT..

Hello guys, I bought a used LG V50 Thinq KT 5 months ago and made it as my daily driver. I shot videos for some projects on the phone and I think the problem was because I had a ton of 4K videos on that phone and forgot to delete some of it and the storage probably got full and couldn't handle the background tasks that were mainly running the phone. It began overheating, then frequent freezing of the phone, couldn't even get past the lockscreen because it would just freeze everytime I opened it up. It then just boot-looped everytime I tried to turn on the phone. I actually did the factory reset where you press the power button and volume down button, It went to this factory reset mode and decided to wipe everything. Unfortunately after a couple of seconds it said "Erasing" then it would just boot loop all over again. I researched some tutorials on youtube on how to unbrick phones and want to try to flash a new stock LG V50 ROM. I've downloaded everything and the correct version of the ROM because I can still access the IMEI on my phone. What my problem is now, is that I can't access the bootloader because I haven't turned on the OEM bootloader option on the developer options. I am completely stuck and want to find a way how to turn on the bootloader on this phone without accessing the developer options so that I am able to flash the new stock ROM via LGUP..

any solutions yet ?

Get into download mode by holding vol + and plugging in usb
