[Q] My Phone wont boot up! HELP - LG Optimus G (International)

Problem SOLVED!
Thank you all!

Hi ClarkOwen, would you care to share what happened and how to solve it? My Optimus G won't boot with red flashing led.

What rom are you using?
I tried to boot into safemode by turning on with power button + volume down button and holding it till it boot up then I uninstalled framework and gravity box as i think they are preventing my phone to boot up and then I rebooted my phone and it worked
What exactly did you do with your phone? What caused it not to boot up anymore?

There are senarios where you do get to restoer your phone using kdz but then it still wont boot up with red led blinking which basically means the battery needs to be hardware reset - taken out of the phone which would require you to open up your phone which is difficult. Thats why I need to know first what happened which prevents your phone to boot up.

Thanks for your reply. I run stock ROM and was preparing for flashing with CM11. I installed ROM Manager and updated my clockmodwork recovery. Then I boot to recovery when this disaster began. The phone just wont boot.
I followed the instruction found in this forum to unbrick using kdz updater and LGNPST and yes I needed to disconnect the battery first. Open up the battery cover was difficult but I managed to to it. After numerous attempts I managed to complete the step for both kdz updater and LGNPST but that still wouldn't boot the phone. Not even into recovery. I could get to the download mode though.
The last successful attempt with KDZ updater (successful means completed steps) has caused my phone totally dead. Now it won't respond in anyway. No flashing led, nothing. I suspect the battery could be dead.
Is it true that we can't charge the battery when the phone is (soft)-bricked?
Anyone knows how to charge LG Optimus G battery in the case of emergency? Ie. not through the phone? I read post about charging using stripped-out USB cable but I don't know where is the +/- of the battery.

[Q] htc one x bricked. not charging. not booting. only bootloader

usual story.
got an htc one x. flashed unlocked all going well. installed a bad rom (did not make a back up)
froze at splash screen. only late last night i found disaster recovery, so i put it to download and shut off the phone. boot back up this evening and tried to install recovery re-lock bootloader, clear cashe etc but. i got a low battery warning when trying to flash.
i didn't have the latest clockwork mod for charging installed; and battery is too low to flash to it.
this is where things get different. i used the boot loader to power down. i plugged it in to the wall to charge and i got this strange flashing red led(not orange) after about an hour it went solid red. had it charging from the wall socket for well over 4 hours now with the solid red led.
then all of a sudden the led starts to flash red again. so i disconnect the phone and try to boot.... nothing happens. try bootloader mode(power + vol.dwn) nothing.
i had to hold the two buttons then plug in the wall charger. then it went into bootloader. problem is it says relocked AND security warning....... and still after all that time charging. i still get low battery warning @ flash.
so i tried to turn off the device again using the power down option. two things happen here. 1)if the charger is in the screen goes black and instantly restarts to fastboot usb menu. 2)if it isnt in it will turn off and wont turn back on (splash screen or bootloader) until the charger is back in.
so what ive done as of now is plug it in to charge over night and hope this thread can shed some light.
additional info:
ruu version: 'RUU_ENDEAVOR_U_ICS_40_hTC_Asia_WWE_1.28.707.10_Radio_1.1204.103.14_release_257076_signed.exe
os version: 1.28.707.10
clockwork mod version: 5.8.2.7
plz any help would be invaluable
EDIT: just turned on phone about ten minutes after i plugged it back in to the charger (held power button alone) splash screen is back (yay!!) but still battery low when trying to flash in
fastboot usb. ima try in the morning after a full night to the charger. fingers crossed

srry posted last night but would not show the thread... so i figured i couldn't so i tried to post in an existing thread. now i dont know how to delete that other one...
FIXED
well never mind the fact that i loaded a plethora of info onto this post and nothing.
but besides that i got it working. in the disaster recovery tut it only lists using the ruu through a flash... never stating that you can just run the file directly and not go in %temp% and get the rom.zip(excepting for the recovery_signed.img). simply find your version of the ruu that you need, flash back to the stock recovery image (within the rom.zip) relock bootloader place device in fastboot and run from pc.
the only hard part is getting it to charge... dont know how mines took charge but i pluged it into the sockets @ my school (long story read this thread: http://forum.xda-developers.com/showpost.php?p=26156147&postcount=20).
when i pluged it in the light went solid red instantly no blinking. after about an hour of charge i pressed the power button and it went to the splash screen (still was on a older CWM which doesn't support charging) left it at the splash screen for the remainder of the class (about another hour) unplugged entered bootloader.
@ this point i had no security warning under relocked. but i used the power down option, took it home and tried to unlock/flash to the latest version of CWM so i could charge. it worked without a hinge.
anyone know why it took charge on an older CWM?
note i got the phone back up and running and the first thing i did was make a nandroid back up
hi i dont have an answer to your question but i have a question to your answer am curently suffering the same problem i can flash the stock cwm because of low battery, and i know when in boot mode it doesnt charge so i rebooted the phone it took me to the htc logo and its displaying a solid red light does this mean its charging or what (the boot loader is re-locked so i can flash stock cwm but cant due to low charge)
Noob badly. But I think it should be charging. Could b wrong. Leave it there for a couple of hours and try again. Mayb fixed. Give it time and try again.
Sent from my HTC One X using XDA
Same thing is happening to my phone. and its bootloader is locked and cannot be unlocked because of the charging. its usb debugging wasnt turned on either before it went down.
Please help anyone?
Guys I have Htc One X. I rooted it then I thought to install a custom rom (resurrection remix) and gapps. so when I was in the CWM recovery I installed the mod while it was installing it said error no file contents but it installed successfully anyway. after that I installed Gapps but it got an error and said Installation aborted. I then started panicking and I tried to restore the backup but nothing happened, then I re-locked the bootloader with battery below 30% then I used the batch file to charge it then I unlocked it again. Now I want to download a stock rom I tried 2 one was a newer version than what my phone actually is and the other one was a lower version than what my phone actually is. I then tried alooooooooooot to search for the appropriate one for my phone but I didn't find it so I thought to continue with installing custom rom anyway but the problem is that I need to get the new mod zip file and new gapps zip file into my phones sdcard but I can't do that/I don't know how. My phone isn't recognized by my pc ( I can't browse it's files) and I tried using adb in command prompt which is very complicated for me however I searched on the internet and tried to do the same but then it says "adb server is out of date killing" then I found one adbFix.exe that said that the adb in HTC sync manager folder is causing a conflict but then the Fix file said that its ok and no problems are there. Now I need to put custom rom and gapps zip files to my phone's sdcard but I can't. Please I would be very grateful to anyone who would help me and guide me and If I'm posting in the wrong forum or thread then please forgive me for this is my first time I made an account on XDA and my first ever comment/

So, I've been seeing A LOT of threads regarding bricked devices (be it soft or hard bricks). So, I decided to create this thread, so everyone with bricked devices post here for help, instead of filling our forums and XDA servers with a load of topics with the same stuff.
If someone knows of a general unbricking thread, please PM me or tag me with a link so I can post on this post.
I will PM a mod to pin this thread to top.

Guys My ION LT28h got bricked during a recovery using CWM.
First It was a soft brick, i did something , random pressing of buttons made it worse. its on HARD BRICKED STATE now. Its been more than 5 weeks.
So after some research i found out that my Kernel is ****ed up. My phone is Boot loader Locked, so i cant flash the Kernel separately.
Now few of our fellow xda members told me to unplug the battery cable from the motherboard.
I have successfully disconnected the battery cable from motherboard, i kept it disconnected for one whole night.
Whats the next step ?
Will i be able to flash it with flash tool after connecting the battery to motherboard back ?
Will i be able flash the busted Kernel to a working stock kernel ?
Accidentally messed up and soft bricked Ion- LT28h.
xperia Ion LT28h
ROM: JB 4.1 Pure CyanogenMod Based on CM 10 FXP 218
kernel: GI Kernel v3 or v5
Recovery: TWRP and CWM
Rooted and Unlocked Bootloader
Hi guys, above mentioned were my previous settings. Had occassional reboots and sometimes it was kinda laggy that's why i decided to flash it to another ROM - supposedly to ParanoidAndroid. After following steps to install PA, my phone was on bootloops, was in a hurry then freaked out, i tried soft and hardreset, and tried booting on recovery both on twrp and cwm to flash properly as what was instructed however i may have flashed the wrong zips interchangeably with other roms and kernels resulting to a total messed up ion. i could have restored immediately to a saved CWM or TWRP backup right away however, i only stopped resetting when my phone suddenly stopped responding, no Sony logo, no Xperia logo, no boot, just backlight on, does not turn off, soft and hard reset no nothing. i guess until the battery went dead, then i charged it the whole night.
after reading most threads on recovering softbricked phone, mainly this {RECOVER SOFT-brick}[2012 XPERIA's]Recover ALL 2012 XPERIAs from SOFT-brick thread, and after a couple of days of red led, i constantly charged, i patiently waited(2days) still no green led, however i found out that i can access fastboot. (blue led).. i managed to get to this fastboot mode(blue led) ONLY after i soft reset or power+vol.up/1 vibrate the phone once the backlight lits up- on&off - for about less than a minute then it goes back to red led. (i'll be calling that stage as backlit-on&off-then-back-to-solid-red-led cycle) but then again if i go to fastboot, it will stay in fastboot mode during flashes and it stays there until the battery runs out and goes back to red led. then i charge my phone again, but
during fastboot mode, i have tried flashing the kernel, system and boot image. all via Fastboot command prompt.
and all were successful. there were combinations like, flashing only the kernel, tried flashing kernel and system, tried boot image only, tried all the same time, tried system only, tried different kernels, system and boot img, BUT STILL my phone wont even give me the sony logo screen.
then i thought i may need to wipe cache and userdata so i also erased cache and userdate a couple of times via fastboot mode command prompt. and yes fastboot does detects my phone. it can reboot to bootloader or just the normal fastboot reboot. so i have no issues regarding phone and pc via using fastboot command prompt. and Same thing - all flashes were successful,
i have flashed i think more or less than a total of 50 times, flashing different combinations. Still it goes back to brick mode.. backlit-on&off-then-back-to-solid-red-led cycle.
i'd like to add that i have also tried flashing via fastboot mode using Flashtool. (thunder icon+selecting 'fastboot mode'). i have flashed the kernel and system, tried kernel only, tried both same time, tried system with boot.img tried flashing kernel with boot.img too, tried different combinations. again, all were successful, but still same result.
it only goes back to backlit-on&off-then-back-to-solid-red-led cycle.
a couple of days after it went to green. flashmode finally! thinking everything will now be alright, i decided to flash it using flashtool via flashmode. I connected phone to pc, after the solid red led and after backlit-on&off-then-back-to-solid-red-led cycle. and the it goes back to red led then the backlit on&off cycle, after observing my phone for hours i then knew that after, i guess about a hundred cycle of backlit on&offs it really does go to green led by itself and if i'm connected to the pc and flashtool it stays on green led or flashmode, however if im connected only on a wallcharger it goes to green led but will only stay there for like 1-2 seconds then goes back to red led and then the backlit on&off cycle.
then i thought just maybe my battery really needs to die as mentioned, since upon plugging my phone on to a wall charger it goes immediately to red led and there's really no response on the phone except only if you gonna wait for the backlit on&off cycle the n press power + vol up then it will respond and go to fastboot mode or power+vol down which goes to flashmode. then i decided to reset the battery by carefully unplugging the ribbon cable and i did. well, initially it did (led was off for a moment then changed to blinking red then solid red) but i have to go to work that time and had to continue only after coming home from work, and that did not resolved it.
i may have flashed my ion a hundred times or so to this date, still no luck. i have finally decided to re-locked my bootloader- and yes it is successfully locked now. - thinking PCC/SEUS/SUS would get it back to life but i'm wrong - it just cant detect my phone. PC companion detects it as Phone/Tablet only then after selecting Ion on the phone list it always says my device is upto date and no available software. (sad)
I also noticed that flashtool does not detect my phone as LT28h. It only says that it is connected to flashmode. Is that an issue too. I have tried diff versions of flashtool from 9.6 to 9.11 all same. i have also installed fastboot and adb as well as flashtool drivers, it sayas all were successfully installed however if im connected via flashtool flashmode, none seems to be detected on device manager, tried reinstalling and manually installing the sony sa0103 adb interface driver however after installing i get an error unable to start device. even if my phone is connected still the device on devicemanager still has an excalamation point. i'm using windows 8. i have flashed successfully before when my phone was in good state, however now that im on brick mode it seems that all flashes i've done did not push thru. also those times that i have flashed my ion via flashtool it says something like:
phone should be connected with usb debugging on and enabled install on unknown sources. i have tried flashing it using win7 pc phone was not detected still, however flashtool stated and detected my device was connected on usb debugging mode, but have has errors during flashing though.
since my bootloader is now locked im unable to flash now via fastboot. before bootloader status says- rooted now bootloader status is- ROOTABLE.
i previously owned xperia neo and have managed to flash it successfully without any issues, also this is the 3rd time i had bricked my ion and managed to fix it before..
i also want to ask regarding flashing back to stock - does that mean any stock firmware can be selected? can be .233 / .68 /.20 or the latest ICS 6.1.E.3.7? coz i have basically tried to all of those mentioned. also is the reason that my flashes were not successful is it because i was currently on 4.1 JB ROM and im flashing 4.0 ICS stock? I also have TWRP and CWM backups on my PC and on internal SD card, is there a way for me to flash or restore those backups via flashtool?
I'm running out of options, i'm desperate and on the verge of giving up.
i dont want to believe that i have totally messed up and hard bricked my phone. I do believe that there is a solution to this, and my phone can be recovered without sending it over to repairshop.. Today is the 3rd week and still struggling to get my phone back to life (even just the sony logo) . any suggestions before i unlock again my bootloader? please help. Any help will be gladly appreciated, and many thanks to everyone for spending time on reading my messed up and soft/hardbrick ion experience.
If you brick your device while flashing kernel and device do not respond any way then follow this little difficult but 100% sure method.
- Dissemble your phone.
- Disconnect battery ribbon from motherboard.
- Reconnect battery ribbon.
- Fastly connect USB cable while holding vol +/-
- Flash Kernel or FTF FW.
Just looking for some direction on my Xperia Ion that recently got bricked while attempting to update to JB software.
Currently, it has no response except for plugging into charger giving a solid red light. I am unable to get it into flashmode and have already disassembled and disconnected/reconnected the battery to reset it.
Im gonna guess that the kernel is royally efed up at this point, Im unable to get it into a bootloop either.
What is the next step to solve this issue? Any help is greatly appreciated!

I think that you should charge it more to be able to go into flashmode. Maybe until the red light will go off or it'll turn into green. Then try to go into flashmode. Good luck

This is my first time got hard brick on my phone. I'm flash wrong ROM (it made for S but I flash it on SL) now my phone totally dead. When I put on wall charger it show constant red led and off several minutes later, try disassemble phone and disconnect and connect ribbon doesn't help to get flashmode and fastboot mode. Any help would be very appreciated.
EDIT: After disconnect ribbon battery I got notification on flashtool "device connected with usb debugging off" but led remains on constant red. Should I try rubber band tricks?

After disconnecting and connecting back the battery cable , you wont get access to flashboot/flashmode instantly. disconnecting the cable will reset the phone.
If you are getting red led means , its charging on low power. You should keep on wall charging for some hours , say 12 + hours.
After that try flashing the kernel alone , first . you will have to hold the flash mode button for sometime. say 5-10 minutes. then if u have enough charge in your phone it will flash the kernel alone. if u are successful in flashing the kernel, then charge again for some hours , 2-4 hours then try to flash the entire ROM.

Thanks for your fast reply, but I'm already put on wall charger 1 day, and the red led got turn off (no led at all). I think I'll try rubber band trick tonight and leave it till morning.
Hey guys I'm having a problem with my Acro S... It's bootloader is unlocked.
It was soft bricked due to a command I ran on Terminal Emulator (dd if=/dev/zero of=/dev/block/mmcblk0). After inputting that command I safely turned off the phone (Long press Power button, Choose Power off). After turning off, phone was completely dead, no response. It was on 80% battery for sure. It happened last week Saturday (July 20). I then charged my phone for 2days+. On the first day (July 21), no red LED appeared, on the 2nd day (July 22), constant red LED appeared, 3rd day (July 23), red LED disappeared. I then prepared my flashtool for flashing the JB firmware .211 KERNEL ONLY. So I plugged in my phone with volume down pressed, I pressed it for 15mins! My finger was f*cked, after 15mins... nothing happened, RED LED just disappeared and I just heard the Windows USB sound. Flash process didn't start, phone didn't give me a GREEN LED. I tried it again and again and miserably same thing happens, can't go to flash mode. Tried the same with volume up button for fastboot mode but still nothing happens, the RED LED just disappears!
Should I just leave my phone charging on the wall socket even if the RED LED disappeared? To get green LED?

T999 Won't boot/start

Didn't find anything similar on here so I had to post. My T999 no longer boots except for a vibrate when the battery is removed and re-inserted. Occasionally it will get to the CM boot logo and then the screen goes off. If I time the button presses right, I get to the Download screen but before I can hit the Up button to confirm download mode the screen shuts off. This happened all of a sudden yesterday, the last activity being to shut off the Alarm. Tried charging but it will not get past the initial battery icon before the screen goes off. Tried replacing the battery but that didn't help. I also tried to follow the debrick instructions but it didn't help. I was running Vanir AOSP 4.4.4 with no issues until yesterday. The device does not register when connected to the PC using USB and the charger LED does not light up when plugged into charger/PC. My feeling is that something went wrong with the boot but I am unable to get into any usable screen to do anything. I had managed to brick a Samsung Vibrant before but I didn't have to struggle as much to debrick and ODIN back to stock. Any help would be greatly appreciated, I'm now without a phone .
Mine is also acting like that. It wont boot to any rom even stock ones. But i noticed that if i connect my charger it will boot to the homescreen. Sounds like a battery issue right? I also thought that but when i go to recovery, it did not shutdown after leaving it for a couple of minutes. I'm also baffled why it wont boot. I'll try to borrow other battery to test if it still the same.

Remove battery snd put back in. Does the device try to turn on by itself? If so you probably have a bad power button.

Boot download mode and flash stock or root66 firmware with Odin. (You may need to factory reset too)

Done this using root66 but still the same. Now my phone went to worse. It wont get past the S3 logo in the boot screen and just shuts down followed by a vibrate. But if i connect my charger, it will continue and run as normal. My suspect might be a bad battery but the thing is it doesn't auto shutdown when is download mode or in recovery mode. Will try to borrow other battery and update if this fixes the problem.
This is pretty strange. Woke up to my phone with the Galaxy s3 boot logo. And it wouldn't go past it. Tried flashing different backups I had but none of them let me go past the boot logo. Flashed CM10 since my version of TWRP recovery is so old that it can't flash anything higher up, and it goes past the boot logo finally after 2 hours then goes to the cyanogen boot logo but doesn't go past that. I'm going to try with ODIN tonight.
Seems very strange that there are others that had this happen to them to. My phone has never done this before, and it happened randomly.
What does it mean if my phone doesn't boot past the logo with an odin to root66 file?
Edit: Nevermind seems to have worked... for now.
Edit 2: Okay so now it's stuck in an infinite loop where it boots past the logo, shows the android mascot then does an android is upgrading app 1 of 169 then goes back all over again. This is fun! Can anyone help?
Edit 3: Okay so I had to do a factory reset. Got it working now. Starting to get sick of the things I have to do to get updated firmware. Samsung needs to get their crap together!

Hopefully its just the battery.
Download mode may work because of how the battery reports to the os. If its going bad and reporting incorrectly that its low, it may trigger a shutdown. Whereas in download mode the os isn't running so its not reading the battery info the same way. Just a guess.

Just for future reference, factory resetting solves about 98% of boot hangs.
Still for both of you, id take this as a sign that you should make sure your backups are up to date. If something is failing you'll be glad you did!

Yeah factory reset unfortunately didn't work for me when I needed it before I had to ODIN to root66. But I was able to do a nandroid after I couldn't get it to boot and extract my sms from Titanium backup. What an awesome app, super thankful to that dev for making it.

Hopefully its just the battery.
Download mode may work because of how the battery reports to the os. If its going bad and reporting incorrectly that its low, it may trigger a shutdown. Whereas in download mode the os isn't running so its not reading the battery info the same way. Just a guess.

Turns out it was the battery sir. I've tested it with another battery from 2 different phones and it worked fine. While the phone i tested with the defective battery didn't event get passed the samsung logo. I've suspected it might be having the low voltage causing the phone to shut down.
Anyways, after that i bought a new battery immediately and everything seems ok. thanks for the reply doc.

Remove battery snd put back in. Does the device try to turn on by itself? If so you probably have a bad power button.

I can confirm that it is likely a bad power button, I have tried everything including dismantling it and seeing if I could dislodge any dirt that may be causing the problem but it didn't work. Looks like I have to find a local repair shop or ebay to get it resolved. Anyone recommend a good place to get this fixed. Funds are limited
Im not sure exactly how difficult the repair is most people seem so do it themselves and have given indications that its pretty easy. You can find the part online for a few bucks.

Black Screen, Blinking Red and Blue LED after boot

Hi all,
Before someone says it, yes I did look around for other threads before posting one of my own. I was not able to find the problem that I am having, nor a working solution.
I am currently running CM12.1 on a Sprint G3 (LS990). This morning, I woke up and found that my phone had frozen while charging overnight. No problem, this has happened before, so I unplugged it and pulled the battery out and rebooted. It was working fine, and then I noticed an update for CM. I hit download, and went to go brush my teeth. When I came back, I saw that it had frozen mid-download. Now it wasn't installing anything; the CM built in updater was just downloading the latest nightly. I waited 5 minutes for it to become responsive, but it never happened so I pulled the battery once again.
Now when I held the power button to start my phone, I saw the LG splash screen as normal. After that, the screen went dark and the LED began blinking red and blue. No matter how many times I pulled the battery to reset my phone, this would occur. I attempted to enter Recovery mode, but in this case after the splash screen the LED would briefly light up blue, and then the phone would reboot, and the cycle would repeat. The same would occur when I tried to boot into download mode.
So now that I cannot boot into anything at all, I assume that my phone is bricked. It is still covered under the limited manufacturer warranty, and since I can't boot up at all I assume it doesn't matter that it is rooted, but before I contact LG I would like to see if anyone here has any ideas.
Before sending it back, have you tried to use the KDZ tool to restore it?

That requires the phone to be in Download mode, and it won't enter Download mode, so I have not tried that.
Well, this happened to me after I flashed TWRP from Flashify on my LG G3 D855 in the day before yesterday and I just had to take the battery out and put it back in, and then I had to boot into download mode. Since you can't even boot into download mode, I'm almost sure the phone is bricked

You HAVE to flash your phone if it was rooted or bump'd, otherwise, it won't be under warrenty, even if it don't boot, they're not stupid..
Every post have: "Your warranty is now void." in it for a reason.

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.

Not sure I understand the question completely, but I did place the phone in download mode as per the method you mention prior to both attempting the KDZ method and the TOT method of going back to stock.
