Boot Loop - Black screen w/ colored LED - G3 Q&A, Help & Troubleshooting

Help! My G3 won't boot up, no matter what I do it boots into a black screen with different color LEDs. I have tried booting into the stock recovery since I didn't install any other recovery on the phone. The hard reset option doesn't work, nor does the safe mode or wipe cache. I can't ADB either since the phone doesnt fully boot up. I rooted with IORoot and everything was working fine.
I made a build.prop adjustment which was "tested" and the OP did show confirmation screenies, but I am the second person that this has happened to.
Any ideas? I don't care about loosing my stuff, I just want to get my phone working at this point. Any step in the right direction would be greatly appreciated!!

Just some theories... Make sure that you don't have kies open while running odin. If that is ot the case.
Try the extreme and flash the rom trough kies itself
Other than that I might sense a sds symptom from what google says((

LG Optimus G Root/unlock isues

Hey fellow LG Optimus G users. Late last month I recently purchased the LGOG on Sprint and came here to seek a root guided. I didn't know that LG locks the bootloader on their devices. I came here, found root guides for 4.0.1 ZV9, 4.1.2 ZVB, AIO, Universal root and to be honest, the rooting portion was fairly simple, but its's unlocking/flashing where I have an issue.
I'm on my third phone. The first phone(unaware of it needing an unlock) I rooted and unlocked using the Universal method and tried to flash a ROM and bricked my phone. THe second time I used AIO root/unlock and my phone still messed up. Here I am once again and I really want to have my phone rooted and unlocked correctly so I can flash Paranoid Android(I like the hybrid ability it offers) but I am too skeptical about it now as I don't want to be out of a phone again. As far as Rooting goes, I feel I can just as easily use the universal method and gain root, but with unlocking, what do I have to do if the AIO way isn't correct for 4.1.2 ZVB? I'm not the best at using ADB and commands lines of the sort but if there is an alternative please help me out. Do I need a different tool? Is it availible on Google Play or is it all on PC?
Look over the guides again.
Use fiddy619 Universal root.
Download FreeGee from the Playstore to unlock.

this is exactly what u want. to add to what engine said... if you reboot after freegee and end up stuck at a black screen(quick lg logo then black).. you are softbricked.. BUT THIS IS FIXABLE. so if the "worst" was to happen.. let us know and we'll get you sorted.

Thanks alot guys, I guess I'll give it another go using this method. If the "worst" is to happen, should I just reply back here? Or PM one of you guys?
Either one of us, and either way is fine. Although autoprime is much more knowledgeable than I. (Not open to debate just in case)

Just unlocked my phone(went and bought the app to support shelnutt). Turned off the phone and then boot back up a clean boot, no error messages. I actually face palmed at how simple this turned out to be. Thanks guys :good:, glad to be apart of a helpful community. I'll play around in TWRP for a while to check its feats.
Edit: Now that my phone is rooted AND unlocked, am I able to remove the bloat apps without issue? I believe this caused my phone to have issues the first go round.
Hack and flash away til your hearts content.
Make sure you backup EFS, and make a TWRP backup and save them to your computer in case your SD gets wiped.

Phone not booting up. PL HELP !
Hello guys !
I have done something terrible and phone is not booting up part recovery now.
I had rooted the phone with one-click universal method without any hasstles and then try to reboot into bootloader by pressing VolDown+Power button.
Eventually ended up rebooting in original android recovery. I tried rebooting with option in that but it was not responding.
While trying it out, I mistakenly wiped cache partition.
Now NO MATTER WHAT COMBINATION I TRY, phone doesn't boot up past the recovery.
Please help me sort out this mess. I need to sell the phone.
I wipe my cache partition all the time. I am rooted but still locked (I don't think that will last much longer). Anyways, in the android recovery with jelly bean, I found that you no longer use the power button for selecting or confirming. It's now done using the menu button below your screen (on the right) . At least that's how it works for my phone.

When I power on the phone I get the LG logo and from there it goes straight to the "fastboot mode" screen, but I can't access the menus. I can also get the backlight screen, but when I connect it to the PC it doesn't recognize the device. I can also access "download mode" on the phone. Please forgive me if I'm not giving a lot of detail. This is my first root ever.
So you can get into fastboot? Did you unlock also? If so, press volume down twice then power. That should get you into recovery.

what engine95 said. Worst case, LGNPST back to stock, and try again. there is a modified ZVB bin floating around that makes you unlocked, and once you boot into recovery, will root you. its the easiest root/unlock ive ever seen. good luck!
remember, the IRC channel is FULL of great help.
i just followed the steps and now im on lg screen computer not reading the phone and cant get in to fastboot or recovery?

Did you use Fiddy69 root method followed by installing FreeGee from the Play Store? If not you can try LGNPST to stock. Or just take it back for an exchange

ive had 4 softbricks today from trying various things...one involved 20 mins of panicked button pushing. keep both volume buttons held down and press the power button for long periods of time then waiting a min or so to see if it comes up to download. Hopefully you will eventually time it right and see the blessed download screen...from there get teenybin's bin file for whatever version you have and use that...its a godsend

[q] Warning for any rooted Tab 7!!!!!

Today I finally rooted my Tablet 7 with some help from gr8nole here on XDA. Needless to say I was very happy and started downloading any and all apps that required root I was interested in. Unfortunately about an hour into my adventure I downloaded an app called LCD Density. DO NOT DOWNLOAD THIS APP. It soft bricked my device after changing the density from 240 to 160. I am now just trying to get back to square one again and have no idea what to do. I wiped the cache partition and re flashed root. Reboot same thing again. The Samsung screen is vertical not horizontal and doing the infamous glow from blue to white and back to blue and nothing more continuously. I am in CWM now and not really sure what step to take next as I don't want to risk a hard brick. I went to Rom Manager in CWM and no files were there when I went to use the backup feature What should I do?

Thank you..Quick question. How do you get into Recovery with TWRP? I flashed it with Odin with the auto restart and with out. I used the CWM Recovery vol up power and home keys but it does not do anything. I am rooted already as well. Could that be the issue? Im using the TAR file too. I really would like to use the touch screen option instead of pushing buttons like a dinosaur

When you flash twrp or cwm in odin, you must uncheck autoreboot. Btw hold down power vol up and home button, when samsung logo appears, release the power button while still pessing down vol up and home

Why didnt you just change the density back? Open build.prop, or push a stock version of it via adb or (idk if it is possible) via fastboot.
Then yoir problem should be solved. Those tweaks have got nothing to do with cache, or data, or so
Thats also why you need root and also the reason, why it is not so easy, to root some devices
But try brain.exe and everything should work, as it should

Workaround:
Make use of your installed/reinstalled recovery system to restore a rom or better nandroid-backup that is already as close as possible to your stock firmware. From there the kdz flasher should work (at least according to my own experience).
This backup worked for me(E986)

I had 2 times problems with low battery issue. I passed it only changing from Diag mode to emergency.
And also it seems to me that the kdz flashing procedure passes only randomly without battery issue. But only on emergency.
I also reinstalled all drivers to reactivate usb ports. With some patience it should pass through

[Q] Bootloop, no recovery...

I recently installed Cyanogenmod on my friends International (GT-19195) GS4 Mini. He said it was glitchy and ****, and he couldn't sign into his Google account. I then turned the phone off, went straight into recovery and installed a stock firmware. Being as dumb as I am, I didn't erase any data or anything whatsoever, I just installed the stock firmware. Now it hangs on the Samsung logo, and I can't get into recovery, pressing the buttons just doesn't work. I can however get into download mode. Help!
