[Q] LG Optimus G Stuck On LG Screen Need Help.

I was making a TWRP Backup when all of the sudden my phone just randomly turns off. I grabed my phone and it was really hot. Tried turning it on, but nothing happened. Then I connected it to the ac adapter and it turned on, but it would go to the LG logo, the screen turns black then it restarts. This does not stop unless I unplug it. I had previously made two backups before and nothing like this happened, but this time I enabled conpression<-------- This must have been what caused this. All I want to know is if this can be fixed or not. If it could be fixed I would be so happy if somone could tell me how to fix this. THANK YOU. P.S. THIS PHONE IS A BEAST. D

It does not let me go into recovery, the screen goes black then restarts. All I can do is go into fastboot and Download mode.

Likely bricked. Do you have flashing notification and capacitive lights? Have you LGNPST'd? If yes to both of those questions, you're in the same predicament as I was and hopefully you have insurance, because your phone is fried.

Sprint's policy on root is to document it but not do anything about it, so they would swap it. If you're worried, I can help you restore stock firmware.

Same happened to me. The phone overheats in recovery, so do what you need to do and then get out of it.

Because your phone doesn't know if it needs to be in charging mode or booting. Pulling battery will fix it.

I had a similar problem as you. Upon getting the phone I rooted and used the FreeGee app from the Google Play store to unlock the bootloader. Everything seemed fine and dandy, until one day when I let my phone's battery drain completely. Pluggin it in to a wall charger resulted in the failed boot where the LG logo flashes before going to a blank, but backlit screen. Luckily, the first few times this happened, through a combination of quickly plugging and unplugging the usb cord and holding the volume up+power button, I could get it into recovery (TWRP). Then a simple cache & dalvik cache wipe, and the phone would boot up as if nothing ever happened. Very strange.
Well yesterday this happened again, however, this time there was no getting the phone into recovery. My previous methods of button mashing and plugging and unplugging weren't working. So, I decided to bite the bullet and use LGNPST to get back to ZV7. Now, like you mentioned, this failed boot would automatically happen, without pressing the power button to turn it on. So it was difficult to get the phone to stay off. I found that with the phone unplugged, if you continue to press the power button until the blank backlit screen turns off, AND continue to hold the power button for an additional five seconds, the phone would stay off and not auto power on into the failed boot.
Once I was able to get the phone to stay off, I pressed the middle of the volume key to depress both volume up and down, and then plugged a usb cord that was attached to my computer. This powered on the phone into download mode. Following the LGNPST guide I was able to get to around 67% complete before my phone turned off and an error message flashed on the computer screen telling me to power cycle the phone and reconnect. Well, the whole 67%/85% LGNPST failure is apparently common and not indicative of an actual failure; HOWEVER, my phone became completely unresponsive. It wouldn't power on at all. It didn't matter if the usb was unplugged or connected to the computer or wall charger. So, I was forced to unplug the battery. I followed this tutorial and successfully disconnected and reconnected the battery cord, and the phone shot back to life. It even booted up into the factory stock ZV7 rom. I guess that LGNPST was successful. It looked like I was on my way to returning my phone to breezy's deodexed ZV9 stock rom that I was previously running.
I went ahead and re-rooted, ran the FreeGee app again, and rebooted into recovery. Then I made a backup and attempted to flash my new rom. Now, I think this is where I royally screwed up. I was pleasantly surprised to see my screen layout and all of my settings still intact after LGNPST back to ZV7 and thought I could just wipe the caches and ignore the factory reset and system wipe before flashing. Perhaps it was this, but part of me also thinks there might be something wrong with my battery draining extremely fast in recovery.
I proceeded to flash and all seemed good, but rebooting resulted in the LG logo failed boot that we have already discussed. So, I went ahead and repeated the LGNPST-re-root process numerous times (switching to the freegee 0.5 batch file instead of the app). Everytime after the first initial restore, I could never get my phone to enter recovery. As soon as I rebooted after using freegee, the phone would be soft bricked again. Sometimes I would get the LG logo thing, other times I would get the dreaded alternating flashing red notification light and soft keys. A battery pull was usually required in these circumstances before I could get back into download mode to start all over.
I was about ready to give up when I took to the LGOG irc channel. That's when Xboxfanj stepped in and helped me out IMMENSELY. Over the course of several hours, he walked me through flashing some partitions in ADB. At times it seemed like there was no hope and that I should have just returned the phone, but he failed to acquiesce, we pushed forth trying a couple of other bootloader options. The new bootloader appeared to have fixed the phones erratic behavior with powering on and off, but I had no rom to boot into and no recovery. Xboxfanj recommended using fastboot to flash over a recovery. Once in the new bootloader screen my Windows XP machine detected new hardware and wanted some drivers. I attempted to use the [ADB/FB/APX Driver] Universal Naked Driver 0.72, but XP indicated that I was missing 'winusbcoinstaller2.dll'.
I grabbed winusbcoinstaller2.dll from here and all was good. Fastboot recognized the phone, I was able to flash recovery and subsequently boot into recovery. From there I reformatted the system, wiped data/factory restore, wiped cache, wiped dalvik cache, and flashed breezy's ZV9 deodexed rom.
Fortunately, after around 7 hours, I am happy to say my phone is back to being rooted, unlocked, and running ZV9. It powers on and off properly and can get into recovery without a hitch. I'm still curious what will happen if I let my battery drain completely. Perhaps I'll try it some time this week. I'll be sure to post back here if/when I do that. All in all, it was a harrowing, but educational experience.
Anyway, just wanted to give a big THANK YOU to Xboxfanj! You really are the man :good:. Thanks for your patience and determination.

I need some help.. PLEASE!

Okay, I've had my Xperia ion (at&t model) for a few weeks now. I decided to root it awhile ago and everything went well, no problems. I also flashed CWM and still found no problems with the phone. I didn't get the bootloader unlocked so I couldn't flash any ROMs. But my buddy wanted to use the phone so I factory reset it in CWM, and rebooted it. It wouldn't go past the sony sign so I did a soft reset and went back into CWM and set my phone down. My buddy thought he was doing me a favor and wiped everything for me because he knew I was having troubles. Including the system. Now I cannot get into CWM, the phone is either just a black screen with a red or green LED, or stuck on the sony screen. I can't really think of anything to do. Sony update service and sony companion both won't work. They have some sort of error when I try to use them. Oh, and the flashtool won't work remembering I can't get into fastboot. Can someone please tell me what to do? If I wasn't specific enough I will try and give you more details if possible. thanks in advance!!!

Dont worry. Hold power and vol up buttons for 15s or till you feel three vibrations. Then use Sony Update Service to repair the phone.

What do you mean by "not working"?
SUS don't recognize your phone? Or your phone won't get into flashmode?

[Q] I think i bricked my Arc, flashtool always gets stuck!

So my phone was running perfectly until i decided to sell it, unfortunately the sales man wouldn't accept my Xperia arc because i had AOKP, i opened recovery mode, choose restore, and i selected an old back up to restore, i thought it would bring my phone to stock.
But then whenever i turned my phone on it would crash with the AOKP start animation half blank, like the bottom half of the screen is completely black.
I googled "my xperia phone is bricked" and i heard that i can flash stock ftf to restore the phone, unfortunately flashtool gets stuck at around 8-13% percent every time.
I tried MANY different versions, many stock roms, turned off my anti virus, changed the cable, booted into safe mode with networking, it still lags. :crying::crying::crying:
Now whenever i boot it up it shows a phone with a warning sign next to it
I looked these forums up and someone suggested that i relock my bootloader and try the Sony update tool, i tried it but it says phone is already up to date
Now my phone is dead, battery ran out and it doesn't show the battery animation when i charge it, does that mean it's not charging?
Please help me, i just want to flash a stock rom and unroot it so i can sell it.

PC companion keeps saying i should turn on my phone, i can't turn it on.
I flashed KTG kernel and now the warning sign doesn't appear, only the Sony logo, whenever i try to turn the phone on it just shows the Sony logo and freezes, i tried to get into recovery but i can't, the led doesn't flash so i can enter recovery.
Thanks though.

YES, it's working again, thank you very much!!!
I "repaired" with PC companion and it wouldn't start, it still lags at the Sony logo, but after repairing it with the pc companion i was able to flash stock ftf without any problem, it's very weird flashtool always lagged before, i think it's because i repaired it now, or maybe because i charged my phone over the entire night? can a low battery cause flashtool to lag?
Anyway that doesn't matter now, thanks again.
My phone is working again after flashing generic world stock ROM, now only thing remains, how do i unroot and relock the bootloader? or is it unrooted already since i flashed a stock ROM? :\
I just want to sell the phone but unfortunately rooted phones don't sell here, every salesman i met rejected me, i want to unroot the phone and relock the bootloader, i just want to make it look like a brand new phone, it's in an excellent condition hardware wise.
I heard factory reset would brick my phone so I will wait until the phone is done booting up and i will download root check and see, i will also check if the bootloader is locked or not from the service menu, after that i will update this post. :good:
EDIT 1: Okay this is very awkward, my phone's battery is completely empty, i have no idea why it's at 0% even though i charged it over the entire night???
Anyway once it's done charging i will check the root and bootloader condition.
Sorry for my bad English.

If you flashed stock firmware, then root is already gone.
And if PC Companion installed firmware to your phone, then bootloader is locked, otherwise PC Companion would have not worked.
If you are still sure, that bootloader is unlocked, check the tutorial in my signature, it includes information how to relock bootloader.

need help with my bricked xperia play r800a

first, I will explain my phone condition.
from off power. If I try to turn on by holding power button, I can feel it vibrates as normal when it turn on to boot up. But for my xplay, its screen show nothing and it seem that the screen does not turn on at all. Then if I plug it to pc from this condition, the pc will ring detect device sound and unplug device sound and detect device sound and unplug device sound, repeat and repeat forever. So I have to pull off battery to turn the phone off. But flash mode and fastboot still work with flashtool.( as you all know plug usb with back button and search button)
what I have done so far to solve this is :
- I have tried to flash stock rom R800_4.0.2.A.0.79 and r800a_2.3.3_US Generic via flashtool in flash mode. flashing is complete but my xplay still remain unbootable.
- flash doomkernel via fastboot with flashtool. process complete but again, problem is not solved.
any help ?

So let me get this straight, you flashed a firmware and your phone is still unbootable and just has a black screen? hmm strange.. Have you tried Sony PC Companion?

I'm sorry no one could help you out as of yet, this issue does seem quite rare so we can expect why you haven't gotten any help and sorry bout that. I would probably flash the different types of firmware and see if theres any hope there, or you can send your phone to repair and that should be your last to resort solution.

When did this happen and how? Such things do not happen without a history, we need to know what you did/tried before to see if we can fix it!

Remove phone and insert it then hold back button(or search button i dunno, but don't turn it on) until the power button shows blue light(or green) and insert the usb cable into the computer. You must tick the two box when flashing stock rom. Check No final verifications and Reset Customizations. Are you trying to use stock rom with doom kernel?
I had this problem too.

Have you tried flashing different Kernels and ROMs?

I had used several custom rom before, the last custom rom is something with lupus kernel (sorry I cannot remember its name). At that time, I have many problem about performance such as when I got a call (the phone start to ring and vibrate) the screen won't show anything, I have to wait for several second before screen show up and I can recieve the call.
One day during on a trip, I designed to turn the phone off and pull out sim card. and used my friend's iphone4 during the trip. When I back home. I tried to start my xplay again. But the phone won't start anymore, it become the state as I mention in this thread.

I have not tried 'No final verifications and reset customizations' yet. So I will tried this when I got my phone back.
ps. I sent it to sony service center last week. Yesterday, they call me that it is hardware failure, and they don't have spare part. But I think they just cannot figture it out what is the problem and don't want to bother with old phone. So I call it back. still wait it to be back in my hand.

[Q] Xperia ZL Loops on Sony Logo (Tried Everything)

Hello everyone
I have been a silent follower of xda from past 4 to 5 years and never had to ask for help
as I could figure out my way through when i get stuck untill now
My Xperia ZL loops on Sony Logo
My phone does enter FLASHMODE and FASTBOOT mode and im able to flash ftf Firmware without any errors in flashtool
but when it asks to unplug and restart my phone i get the same loops
I have tried yellow button Soft reset (stays in a loop after reboot)
i have tried yellow button Hard reset (Powers off after 3 vibrations)
I gave it to sony service here in India(Hyderabad) they are suggesting me to replace the motherboard which costs 24,000 INR/-(Seriously?)
i bought the phone 2 years back for 29,000 INR/- and now they want me to pay 75% of the price I strongly believe they follow their blind
rules of pushing the customer to go for motherboard replacement if they are not able to revive the phone after basic software flashing
but i still believe i can recover my phone if all the gurus out here can help me out
The phone still didnt go dead till now(some battery left may be still looping) ill try once again if the battery dies completely
EDIT:1
Tried flashing New 5.02 lollipop ftf, after successful flashing with no errors
unplugged it and tried to turn it on
Now red LED flashes 3 times but the device doesnt start
connected it to a wall charger and now i can see the kernel charging screen with battery symbol showing the charging
after some 7% charging indicated i tried to start the phone and the same inevitable loops with sony logo come back

Just plug it in and let it charge for a couple of hours, if it still bootloops, try Sony's Flashtool EMMA. I know people say it's ****, but it fixed my phone when I was in the same position as you.

CAUTION: IT IS FOR XPERIA Z >BUT IF U KNOW CORRECT POINTS THEN TRY IT for ZL on your OWN RISK.
otherwise as i said try to replace whole battery will have more chances to bring back to life.18-20 $ will be enough.

sony service centre ! They never do repair on z series.If it's in warranty drop it on service centre .they will give you a refurbished phone.
IF warranty is over you can ask them .But i m 100% sure they don't do repair as many other countries.Depends where you live.
you can do it on your own @ your own risk.Remember battery is slightly glued underneath the screen.
Always remember to order battery with that cables and connection.
Sorry for long reply .But in this kind of matters we are frustrated & you don't want to waste money & our phones.

use button
use the tiny button beside sdcard press that untill 3 times vibrate and hold button vol down in flasmood mode

Try boot with USB cable connected to 1.5A+ charger with good cable.

No Hope guys tried everything im pretty sure its battery problem but the service center guys dont want to listen to me at all
all they want me to do is get it replaced for a new phone for 24,000 INR (360$) are you kidding me? for a Xperia ZL
Im even ready to give away the phone if someone wants to help me out

I have the same problem with my ZL. Service center refused to replace the battery, so I asked someone else to do it. That however didn't fix the problem. When I push at the back between the flashlight and XPERIA the phone will switch off. When I disconnect the battery and connect it again it will start-up again. I removed the screw below the camera module, as fastening that one also made the phone turn off. There is something wrong with the motherboard. I always had my phone in a flip case and it didn't even have a single scratch on it. First time it went of was while making a video. Possibly overheating caused this problem or damaged a circuit at the motherboard. Very disappointed, phone was just 2 month out of warranty, first time off was within but that doesn't count.

Tried flashing New 5.02 lollipop ftf, after successful flashing with no errors
unplugged it and tried to turn it on
Now red LED flashes 3 times but the device doesnt start
connected it to a wall charger and now i can see the kernel charging screen with battery symbol showing the charging
after some 7% charging indicated i tried to start the phone and the same inevitable loops with sony logo come back

I was in the same boat as you with my refurbished ZL. Flashed anything, doesn't boot. Then battery full drained and only red light. Service told me it's motherboard circuit. I didn't lesten them, bought cheap battery and replaced it by myself: and Xperia worked like a charm but only 3 months ))) New (cheap) battery got trouble on GPS route suddenly. And phone worked only with power cord connected, shutdown without. New battery will again fix it )
