Blank screen after unlocking (E975) / abnormal boot-behavior

Hi everbody!
After unlocking my LGOG (E975) a weird issued appeard: When phone is in standby and I try to boot it up as always (before unlocking) by Long pressing standby-button for a few moments, the LG logo comes up, and then only a black blank Screen (after 10 minutes or so this repeats) If I immedeately after disappearing LG-logo I press the standby-button again, the well known animated logo appears and everything is OK.
On the other Hand: when I connect a completely battery-empty LGOG ONLY the black Screen appears, after some reboots with hold standby-button the White battery loading Symbol appears...
Has it something to do with Fast-Boot (how to change any options?) or with unlocking via FreeGee. So far I was unable to find any similar issues like this... It bothers me always to press standby-button twice to boot up. If I missed the correct Timing I have to hold standby to turn off the phone correctly. Please help me!! Thank you guys!!

Wrong thread dude.

Oops, thanks man. Could an admin please move my thread to the Q&A section? Thanks!

Same here. I wanted to write about this myself. Did you Install TWRP or CWM? Someone who useses exactly the same SW baseband kernel and LG ROM like me as a base does not have the issue and we were trying to figure it out. He unlocked installed CWM and CM10.1.

OK, so getting back to business i can see this is a problem when charging the phone. If i shutdown, then charge then in the morning unplug > phone shuts down again (from charging mode) and i power it up it doesn't boot the ROM.
I tested this situation and i saw that sometimes it doesn't even enter charging mode after a shutdown. I will test later and comeback. Maybe others can relate and give ideas.

Same here
Hello,
I have the exact same problem with my Lg e975.
If the battery is empty , i can not turn my phone on while charging. I think it is not even charging sometimes. I thought it was because of charger but i think it may because of phone.
Today i am charging 10 minutes still phone going black screen after LG logo. :crying: even not sure if it is charging.

Any solution for this? I have the same happen to my e975. I figure using freegee somehow corrupted the bootloader, so plan on either flashing a new bootloader or just an official update from LG and start from scratch again? Has anyone tried this?

Problem is its my wife's phone so wont try it until i get my nexus 5 and she can use my nexus 4 if i brick it.
***edit*** according the Houstonn, the bootloader located here: http://downloads.codefi.re/houstonn/lgog/misc/cwm-geeb-4-3-z20i-bootloader_only.zip it should be able to be used on any LGOG. IF you are game give it a go but i won't be responsible for any bricks. I will test it when i get my nexus 5. Its a 4.3 bootloader that can be flashed using CWM.

No idea mate. I assume you would have to find a full stock rom and just flash that via normal update methods. I don't plan on ever going back to the crap that LG call stock.

Happened again just now.
The problem is when it is at this strange black screen it is not charging!
Just i put my phone to charge left there 1 hours. Just wanted to turn on but didn't. Pluged of the charger and phone is not booting because battery seems to empty. Just i put it back to charge and restarted it 10 times nearly. Now the phone turned on and started to recharging from 0!
I feel like phone going and coming back to life. Some day will not turn on.

Ya.. . Lg phones has this weird behaviour.... Even with charger plugged and empty battery you can't switch on your mobile... I think it always take power from battery even with charger connected....

[Q] Bricked , any way to unbrick !

Hi all , I've bricked this device about a month ago , I've been searching for unbrick method , I can say i searched the entire internet i was unnable to find any unbrick methods , nor new mainboard , I even conntacted huawei in the us , and they told me to buy new motherboard in alibaba.com there's no motherboard there to , I was supprised they to have no mainboards nor support for unbricking the device ,
so my question , Does anywan know how to do it, or where can i pursache a new motherboard.

You kind of need to explain the symptoms before the doctor can do anything, same thing applies here.
Explain what is happening on your device, No response / stuck on boot animation, will it go to Recovery etc.
Also what have you tried to unbrick. Give us some info otherwise we can't help.
I haven't seen any P6 Mobos for sale on Ebay and such, I wouldn't know about that.

Explain here... You'll get your phone unbricked. Never say die

Well , I was trying to flash the CleanRom project , I'have made a post about that to ,
The Instructions were wery clear to me i followed them exactly how it was writen in tutorial.
I have an international verzion of P6 and according to that turorial , ( http://forum.xda-developers.com/showthread.php?t=2625680 )
in order to flash that room i moust firstly flash an Chineze verzion which comes with unlocked bootloader , then i did that
I downloaded the rom put it on phone flashed via setteings update software , then everything went fine the process it seelf showd me
completed 100% and in the end sayd OK , then my phone turned off, and it's never been on eversince :A
As of now the phone is totally dead black screen , I've tryed everything it doesent go in any mode
When i plug in the power cord it only shows a red light indicator.
I belive this is a Hard Brick , not soft brick .

Yes i did brick my P6 and nope I aint gona tell them Im a noob :A
The thing here is to get help in here is not about send it back to china so if you have any other idea , your welcome to share.
I have no warranty , even if it had this phone is buyed in china , and traveled to the otherside of the world :it would cost as mouch as the phone itseelf to send it back to service.

Try flashing the latest TWRP, it has off mode charging. Can you put your phone in fastboot mode via adb ?

Not Hard Brick!
Happened to me before and guess what? Tried very simple thing - and it worked.
Take your sdCard out of the phone.
Replace the dload folder with the extraction from either the B111 from the Huawei site or the B125 from here on xda
Reinsert card and press all buttons down till phone goes into internal recovery.
Your main problem will be having enough battery to get you twenty minutes.
If your red light is functioning, you probably haven't blown your motherboard.

Only solution for that is to take your phone to local service. I am talking from experience.
Sent from my ME371MG using xda app-developers app

Can you check if you plug it into you computer that your computer connects to it or makes a sound? That can probably prove that the motherboard is fine and maybe your LCD is broken or has loose connection.
Happened to me before. Black screen, only red led, nothing else working. It happened that I got scammed by a seller.
What I ended up doing was taking apart the phone and I found that the LCD connection was loose. Fixed that, then I saw that the phone wouldn't boot. Loaded B111, B118, nothing worked. I then got B125, and it miraculously worked.
You could try what I did, but it is quite risky and I was very lucky.
I have to agree with goce. Unless you are experienced and willing to mess around with things, you should go find local service.

I think you should download the TWRP recovery for jelly bean from surdu and flash it from bootloader. If you are on the international this is the method for unlocking bootloader:

g3 Stuck in Download mode. Help Please...

I just got a new LG g3 sprint variant yesterday. Worked fine for about an hour. Started crashing. Green Screen with crash handler with options to reboot or dump. It would boot up and then crash again. Also received a Kernel crash black screen. So I decided to flash new dll file and tot file using lg flash tool. Put into stock download mode (firmware update Screen) and started flash. Went to 19% the screen went black acted like it turns off and disconnects and fails. Tried 4 different cords with not very different results. the furthest it got was 49%. Now it is stuck in firmware update screen. I remove battery and turn on phone it goes to lg boot screen and then firmware update. If the phone is off and I plug into wall charger the screen shows battery symbol with spinning thing and then firmware update screen comes on. Please help. Thanks for any input in advance. Posted in Sprint g3 section as well but no answer yet. Thanks

Read it. You might get Download Fail can not restart to download mode a few times. Keep trying, use different usb ports restart computer, try again, restart phone to download mode. I must have got that message 50 times then all of a sudden it worked. Its a pain but see how it goes. There is another way but it is a pain and involves lots of setup.
Be sure to download the right dll and tot files for your model.

Return it. You have a hardware problem that no amount firmware flashes will cure.

This will fix your RED 2. I had the same issue.... basically after you load the .dll and the .tot file, in the lower left corner select BOARD DL instead of usb and after it flashes you'll end up at a screen, click on the "yes" then hold the Power button and tap "Normal" on the screen, it'll reboot and your phone is now fixed. No red 2.

I had identical issues on my G2. I had to persevere with firmware flashes to get rid of root. That was simply so that I could return it under warranty. Believe me this is a hardware issue that will persevere through whatever firmware you flash. Your motherboard needs to be replaced. If you are not rooted I would return it now. If you are rooted then you need to carry on until it shows unrooted in the box at the bottom of software update screen. Good luck.

If your confident it has never been rooted and it is shown as unrooted I would keep on at them. I've no idea about US consumer legislation but I would guess that they need to provide some evidence that you rooted it.

I have everything ready to flash stock firmware. Now my computer isn't recognizing phone. Says device in USB is malfunctioning and isn't recognized. Have reinstalled drivers from lg site, rebooted, different cords, download lg suite and nothing has worked. So frustrated . debugging mode is enabled. Developer enabled. Must be something on phone as other devices work. I am also able to get phone to boot normally the odd time. This is when computer can't see it. Restarting goes to green screen 90% of the time. Never had problems before with drivers and phone being recognized till green screen 2 days ago.

Update to OP situation?
I have only had my G3 since April 2015 bought it from best buy and today I had a green screen tz crash show up with demigod crash handler. I have never attempted to root or anything with this phone. I was wondering if anyone has an update with this situation. Recently updated gmail through play store maybe 2 hours prior to crash.

It's not something you can necessarily view at will or should want to see again. Maybe try a logcat from adb or get a log report from phone recovery to find more info? I personally haven't had the issue happen since I last posted here. Good luck.

[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.

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 )

Need help after hard brick

My phone died while surfing and clicking a link (link was ok I checked on a notebook). It seemed to restart but ended with the LG logo - and after that ended with a black screen. Then I tried every combination to boot again (Volume down+Start button to get into recovery, Vol- + USB cable to get into download mode, took out the accu) but nothing happenend. Just dead. Do you have any idea to let my phone start again? Thanks for any help!

Either the ilapo bootloop. Or if its a hrd brick only fix is octoplus box with jtag support. Were u flashing anything or did it just reboot into a bootloop

What is "ilapo"? And sorry, but I don't know octopus box, too. I wasn't flashing anything, just surfing on a website. For a short moment I saw the LG Logo, after that it was black...

Hrdware failure mother board is bad. Called infinite loop auto power off. Its a defect. Call lg. They may fix it under extended waranty

After I have a read a lot about this specific problem in this forum, I think it's the same with my phone. I will send it back hoping it will be repaired.

Same here

Any idea if LG will fix your phone? I also have a hard brick on my BRAND NEW G4.
I tried TK's root method on my H811 but my version is 10d and seems like it does not
work with his version of the root image (10h).

I hope they will. But ath the same time I'm looking for another phone, too. Because I don't know whether the fixed phone will survive for a long time. Obviously LG shouldn't be the first choice at the moment.

There are even refurbed phones that lg has fixxed ilapoing too. From what i understand no g4 is safe.

Seems like you had an old G4. What is your serial number? Only digits matter. Mine is 602 and so far noone got bootloop on 602, if your is 500-510 ur very likely to get bootloop. You can still turn on your phone with modifying hardware but best way is just to give it back on warranty

Did the same, bought a zenfone 2 yesterday. So far really happy, great for the price. I don't like the bloatware so I unlocked, rooted and installed CM13. Very easy and smooth process. Working great.
