I was curious if anybody could help me. I have a g2x from Wind (p-999dw). I am pretty new to rooting and such but wanted to update my phone. I got it rooted successfully and then tried installing the CM7 Rom update. Backed up with cwm first and then continued. Now my phone is pretty f'd. Every time i try to turn it on it just hangs on the LG screen. I tried the flash recovery method with nv flash and was able to get a cwm recovery menu up but when i try loading the previous working setup, it says successful, i restart the phone and now i get the LG logo with the blue status bar below (which wasn't there before I used the flashing tool) it which moves for a few seconds, then freezes. I've tried every option in the menu and i still cant get past the LG logo screen. Can anybody help me? I've spent hours trying and can't seem find a way to fix it. Don't care if i lose all my data and apps just want my phone to work. Any help would be much appreciated. Thanks.
Hello,
I just recently rooted my phone (LG optimus 3D, Rogers) I didn't like the ROM I installed (cyanogenmod 7) and i tried to restore it back to the original ROM. When i opened up ROM manager and tried to restore , the entire system crashed&rebooted.During the reboot i pressed the power button. The phone stopped responding and forced me to remove the battery. After re installing the battery it booted past the LG logo screen but after all there is is a black screen and every time i press the screen the buttons on the bottom of the screen will light up but that is about it.
I managed to get into the android recovery manager <3e> but when i format all it says is it is unable to mount and load recovery/log
did i permanently brick my phone ? should i try to send it to rogers/LG and see if they can repair it
Please Help!

How did the recovery revert to the stock recovery? Don't you need CWM to flash CM? Anyway, try flashing CWM again and see if you cannot flash another rom just to get Android up again.

Hi, I have a problem with my LG O3D. I have root my phone with superoneclick and then i've installed rom manager. I click on "reboot into recovery", because i wanted backup the rom but when I reboot it gets stuck on the logo LG.I tried the key combination to hard reset but does nothing. What can i do? thanks to anyone who will answer me
O3D is unbrickable unless you have hardware damage. So don't worry , use the resurrection guide to fix it. Search the forum for it.

Hey guys.
I'm new in the Android world and bought an LG G2 back in november.
I had originally intended to custom install cyanogenmod or KitKat 4.4 to replace stock rom, but I couldn't find a way to install a custom recovery, and was only able to root my device via Kingo Android Root.
A while later I saw an update that popped up, and not knowing any better I clicked install. It was about 114MB. That was about 3 days ago, and my LG G2 has been stuck in a bootloop ever since.
When I try to turn it on the LG logo shows up, then it says "secure booting error"and "Cause: boot certification verify" on the top left corner of the screen in white text.
I tried doing a hard reset, but that didn't work. I don't have a custom recovery so that I can clear the cache and data or something. So pretty much I have a bootlooped phone with no custom recovery, I can't do a hard reset, and it's Sprint and everything's new so it's harder to find a fix.
Does anyone here know of a way I can fix this? It would be much appreciated.
Thanks in advance
Just wanting some advice (if any) to a white line issue I'm having with this tablet. I bought this tablet with Lollipop 5.0.1 already installed. I managed to get it downgraded, rooted, and currently have TWRP installed as well as CM12.1 nightly. The problem I have is that as soon as I install ANY custom recovery (TWRP or CWM recovery) it boots normally at first giving me the LG logo. Then, instead of getting the AT&T logo (or the CM custom boot animation), it gives me a series of white lines spamming from top to bottom of the screen. I know for a fact it has to be software related as when I return to stock KK everything boots fine, giving me the LG logo followed by the AT&T logo. I did NOT use the ADB method. Instead I downgraded using the LG Flash Tool, and a test KDZ file, which allowed me to install Flashify, then TWRP. My problem ONLY begins once I install ANY custom recovery. This process did not unlock my bootloader, however. Could this be my culprit, or would it be something else? Any help is greatly appreciated, and thanks in advance for any help/tips. More information is completely available upon request.
P.S. The white lines eventually disappear when the screen goes to sleep on it's own. I can then press the power button to wake the device which gives me the lock screen as normal. I just want to know if I can get the boot animation working. Everything else works fine.
You found cwm?
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
