[Q]Help! I think I bricked my 768 - LG Optimus L9 P760, P765, P768, P769

Hello everyone, I just bought an l9 768 and so far I managed to upgrade it to JB and root it. The problem is I installed some dpi changer app and now all I get is a black screen after the LG logo. I have no CWM (as far as I know) so I can't do a full wipe/factory reset. I tried booting with vol down and it kind of "erases everything", but I'm still stuck. I also can enter SW upgrade mode by inserting the battery while pressing vol up and plugged to the usb, but the update tool stops at 15% saying my phone is not connected, so I can't reflash. Is there any way I can get my phone back? Thank you very much in advance.

Son's Phone - Blue Error Handler boot loop, bricked?

Let me prefice this by saying that my son doesn't know how to flash files, know what super user is, or know how to do much on his phone at all other than watch youtube and text.
He is running either official CM7-RC2 or RC3 for his P500, installing Link2SD and linking a few games is the only tweak I did.
He says it just started boot looping in the morning after charging all night.
My son was complaining his P500 was not starting, I figured it was a very low battery which ended up in a boot loop pattern. The next morning he said he charged it all night and it still wasn't working. Now I knew something was not right.
I pulled the battery, tried to offline charge it, gets stuck at lg logo. Tried to boot with no battery, just the usb plugged in, same bootloop.
Tried to boot into CWM by holding vol up/home and this screen somes up!
Now every time I turn on the phone I'm greeted with this Blue Error Handler message.
Code:

You also might need the p500 drivers installed to use the lg thunder 1.5
You can download it from here
https://dl.dropbox.com/u/46581752/LGUnitedMobileDriver_S4981MAN36AP22_ML_WHQL_Ver_3.6.exe
LGMDP doesn't connect to the phone, it waits at the select port screen. The drivers are installed since LGMDP can see my other P500s.
*edit* I was just thinking, I haven't tried connecting my other phones in emergency mode. Perhaps it is the drivers.
You boot to CMW with home+VOLDOWN+power... you mentioned volup.

It did not detect mine either at first place... follow this.
1) close the LGMPD
2) plug the usb into a different port you are already doing
3) put the phone into emergency
4) connect
5) then start LGMPD
hope this helps
you could try flashing a new kernal/rom through the computer?

I wish I could get recovery going, but it always just hangs and the first lg logo if I hold any buttons down during boot. The only way I can get emerg mode going is to wait for the Blue Error Handler message to come up then hold vol down and back.
Once my phone got bricked and yes nothing detected my phone in emergency mode...so I just kept my phone turned off and plugged in and started doing what the thread said...then it automatically detected my phone and my phone's problem was solved
Please do it at ur own risk...I wont hold any responsibilty.

Mind if I ask how long have ur son been using this phone? To me, it looks like it is due to age. Well that is how I see it.
a cheap trick
This is what i tried on some other phone with similar situation...
use KDZ updater....to update v20g
put to emergency...
start the update (even if the phone is detected or not)
it may or may not install the rom correctly ......but after that LGMDP will start detecting your phone..

ya I've tried updating using KDZ updater many times it always hangs at the point where it says phone not found.
I use Ubuntu on my machine and its a pain to have to reboot to windows to try to flash it, are there any linux alternatives to LGMPD or KDZ? Maybe I'll try the official LG updater full program thing next time I reboot.
I just bought an atrix 4g for myself so I'm busy playing with my new toy
I just got the error it looks like you overclock too high of a frequency u got that instead of the kernel panic. I think it is because that our processor can't handle the oc and crashed.
But somehow I got out of it and no bootloop. Will investigate.

He's never overclocked it on purpose, I just asked him, he doesn't know what overclock means.

Should try. I think it is a corrupt rom or something.
Went to researched and found out that the error happens wipe the /system isn't wiped properly. Try kdz first then install a custom recovery and wipe /system using amora recovery instead of cwm.
not to sound rude but have you read this thread? I've tried kdz multiple times in many different ways. Do you have any kdz tips I haven't tried?

Bit more detail how you bricked it installing CWM. What exactly you done and where you get it from.
Try to shut it down, press power + volume up untill you feel (1+) 3 vibrations.
See if you can connect it in flash mode (connect usb to pc while you hold volue down), the led should turn green.

First I'd like to thank's for your help ChikeD!
Well.... I was trying to install the new CM 11 Nightly Build - a custom ROM build on Android 4.4.2 KitKat- on my Sony Xperia P device
I had rooted succesfully and was seaching for an app on google play store to provide access to "recovery mode" that works with my LT 22i to finish the installation of this new rom... i tryed lot of apps, but no one worked... and so I've found this app "Recover X" from LEDelete developer.
after install and run, this app show me one option to get access to recovery mode... i dont remember exactly, but i saw somethig like "CMW......" on screen. after download, I tryed to reboot my phone and then its completly dead!! i'd tryed any kind of possibility pressing buttons dowloading softwares and more but my computers didn't recongize it when connect USB cable...
vol+ / power dont work, vol- / usb dont work, no charging indicator, no lights blinks, nothing works! it looks like a motherboard without any operational system...
And I saw in some websites that exist one JIG for Samsung devices that alows recovery phones with problems like mine... so i wonder if is possible to find some JIG for Xperia P or any other possibility of reinstallation of android system
I hope i made myself clear because I'm still learning this language... that means I'm sorry for my bad english in advice...
If there is anything that you can't understand, please let me know
Thank's a lot!
Alex
If you had asked before I would have told you Recovery X won't work, didn't work the 2 times I have tried it, but didn't brick my phone eithr.
To incatal CM you didn't neet to root or install CWM since you need to flash it's kernel anyway.
Is your bootloader unlocked?
Was the phone fully charged when it happened, did it start boot and then died or just went black?
Have you tried to hold the power + volume up for 10-15 minutes?
To reinstall firmware you need flash mode (volume down while connecting to USB), have you flashed with flashtool or PC Companion before?

Yes i had reinstalled twice by flash tool and pc companion, holding vol down while connecting to USB, because the device was with very low performance.
When i was trying to get rebooted on "recovery mode" before the black screen, my battery was on 85%....
Yesterday i tried to do "hard reboot" holding the power + volume up for 50 minutes and nothing....
Actually what i really need is find a way to get some response of the system of this phone (by connecting in some jig, or doing something with the software or even the hardware...), because if my computer recognize the phone, i do believe that i'll can handle with reinstallation... in other words, my challenge now it's only get out from the black screen for any other operational response
One of my ideas is unmount rear cover and try to disconnect the battery cord for 10 minutes and see if something changes... but i'm fully opened to new ideas
I really believe that i'll succeed on this case with yours precious help!!
Thank you again for your assistance!

BIG PROBLEM-no Recovery-no DownloadMode-no Fastboot

Hi,
I HAVE GOT A VERY BIG PROBLEM.After i installed the App AutoRec(i had TWRP befoe,but i thougt when i install it it updates TWRP to a newer version) my phone only starts in Fastboot Mode-no DownloadMode-no Recovery Mode.
After that i erased all the things(aboot,boot,cache,system,laf,....) und flashed them again,after that the Phone only starts until the LgLogo then it stops.No Fastboot,no recovery,no DownloadMode.When I Press VolumeUp+PowerOff i get into the Factory Reset.When i press on Erase all user data&restore default settings?---When i press Yes the phone the logo comes an on the left up side stands"Error:boot ceryfication verify
Secure Boot error
Cause :Boot cerification verify
After that the display is black,and i have to restart the Phone.
When i press all 3 buttons on my phone,i got into the hardware key control mode,does me help that everthing?
When i plug in the phone in my pc,it says "unknown device",when i use to do something with fastboot it says"waiting for device"?
Please help me,what can i do?I have the Phone only since 2 two days,an i wouldnt lost it Unhappy
Sorry for my bad english
Can you still get into twrp? With the phone off hold power and vol down til LG logo comes up the release and press again after. Should take you to a menu, just hit yes. If it takes you to recovery just hit factory reset and it'll,take you to twrp. If so, I'd recommend putting a Rom onto an sd and flashing it. You'll lose everything but it's better then losing this beautiful phone

You obviously didnt read his post correctly. He stated that when he gets to the factory reset area which leads you to Recovery Mode/TWRP it shows the LG logo appears and nothing happens.
As for you my friend if you are able to somehow get into download mode with a button combination you have a chance at saving yourself by using a TOT or KDZ file to restore your phone to stock software. But i also have a question for you.........Why the hell would you allow an app to flash a recovery file that has nothing to do with BUMP'D? The Bump'd recovery for our phones is specific to our phones! You should never auto update any recovery unless stated its ok from the Bump'd developers, Which they never did or will because our TWRP Recoveries are different than any other phones because of the bump'd implementations with in them and the boot.img's. Sounds to me like you may have screwed up your partitions and/or boot stack. Your are better going on IRC and requesting the help of TheCubed/IOMonster and AutoPrime, but mark my words you will face some heavy criticism from members of the IRC channel when you explain this story to them. But they are always willing to help.
I dont know why i have done it,im new on Lg.Before i had an HTC there is so many other.I will aks that guys.I hope i can save my new phone.
But the Problem is,i dont get into download Menu,i did everthing

[Q] Beginner at Rooting - My A5 is on bootloop?

Hey everyone, I am new to this type of phone rooting stuff. For some reason I got bored and I read about rooting and thought id give it a go.
I used Odin and it said "Added!" at the end and everything, the phone restarted and I was able to use it, but for some reason the app that I rooted my phone for "Emoji Switcher" said it didnt detect Rooting, so I decided to reboot my phone. Now it stuck on the "Powered by Android" Screen. I cannot turn it off and this model doesnt have a removable battery. I am a newb to this, please help me. I just got this phone. I know, Im irresponsible..

I think you are in the wrong forum....this is for Samsung galaxy alpha. Model # sm-850a/m/f/s/k and whatever other letter.

Since its a nonremovable batt. i think they've added the option to force reset it with holding power button for more than 10 seconds. If that works right after the restart press and hold power+home+volume up buttons and it will take you to recovery in which you can reset the phone to factory settings.

I tried and it didnt work at first, but now it did. I love you sir.

soft bricked my phone... desperate for help..

alright guys, so here's the story. just yesterday i bought a brand new lg v10, got it home and the first thing i did was root the device and used ADB to load TWRP following the instructions here on SDA to a T for the ROOT/RECOVERY setup. and it worked. all was fine and dandy, the first time i booted into TWRP via ADB after root i got in, flashed a debloated ROM + xposed and again, everything went fine.. loaded into the OS of the new ROM, went through setup, turned on USB debugging, clicked always allow this computer, installed xposed app yadayadayada. I then, using ADB again, loaded into TWRP. i created a backup there just in case something went wrong with the changes i was about to make and once the backup was complete i loaded back in to the OS. at this point i thought i had done everything right and was confident that if i made system changes that didn't work out i could just flash the phone with TWRP from the backup i made. right? WRONG! ...apparently... so anyways, i made my first change, which was to use a NONROOT app called texdroider or whatever to change my DPI (as i have done with a couple phones previously without much issue) but i didn't take into account that stupid second screen... making the DPI changes system wide, as i'm sure those of you that know this phone are aware, causes the systemUI to crash with an error.. making the OS unusable.. so i tried to load into TWRP by holding the volume down and power button.. but instead it just booted me to the factory recovery.. not TWRP... the phone is unusable within the OS, i can't get the phone to connect to adb to boot into twrp as i had previously, i can't seem to get the phone into download mode, and i can't boot to TWRP and the OS is junk at this point.. but it DOES say on the "LG" screen that the bootloader is unlocked so i'm really hoping i'm not completely out of luck.. but i am not sure what to do at this point. does anyone here know of anything i can try to get into a custom recovery at this point? if i could get into TWRP my SD card in the phone has a backup, the original image, not to mention i could pull the SD card and add anything i need via my pc and then boot back to twrp etc etc and i would have no issue fixing the phone... i really don't understand what i did wrong or why i can't boot to my custom recovery but i'm at a loss.. i'm just looking for a way to force the phone into a custom recovery... or restore the original factory image.. if you have any advice at all i would really appreciate it.
Thanks for reading
**UPDATE** this may or may not make things much easier... but I got download mode working!! so at least there's that, still no custom recovery and i'm currently looking for a KDZ or TOT file to flash via lg flash tool... hopefully that makes things easier..
When you say you got to the factory recovery, what was that, an Android on its side or something asking you to factory reset your device? If it was the factory reset screen, if you select yes and then yes, it will take you to TWRP if you have it installed. If you don't it will factory reset your device.

To boot into recovery from power off, you hold volume down & power. When you see the LG logo release and press power while continuing to hold volume down. Then as said above, it come up as a factory reset, select yes each time, and it should boot into twrp, providing you installed it correctly.

it was a screen asking me to do a factory reset, i click yes, it asks to confirm, i click yes again and then it "successfully" factory resets my phone... it shows the android factory reset symbol that its resetting, then says that its "optimizing apps" and goes through that whole process.. but when it finally loads the "welcome" screen (so i know for a fact that some sort reset has taken place) i get the same "systemui has crashed" error and the OS is unusable and won't connect to my computer.. idk why i can't access TWRP.. i booted to it 3 times before this happened, though never by the hardware buttons on the phone.. everytime i booted to TWRP i had used ADB to boot to TWRP.. what makes me the most sad is that i have a nandroid backup on my SD card... but i can't flash it without recovery.. which i can't install on the phone without getting into the OS..
is there any way to install TWRP or even boot to a temporary TWRP so that i can do so? if i can flash my nandroid i'm saved.. if i can get into a custom recovery i'm saved.. if i can find a .kdz file to flash, i'm saved... if i can get my phone to be recognized by my computer/adb i'm saved.... there simply has to be a way to unbrick this phone...

To boot into recovery from power off, you hold volume down & power. When you see the LG logo release and press power while continuing to hold volume down. Then as said above, it come up as a factory reset, select yes each time, and it should boot into twrp, providing you installed it correctly.

well i seem to have somehow NOT installed TWRP correctly because it just proceeds to factory reset my phone.. which for some odd reason doesn't reset the DPI... leaving me stranded... is there any way to get ADB to see my device in its present state? my computer makes the device recognition noise when i enter download mode and i can see it in device manager but not my computer or ADB
I've had this phone just over 2 months but I'm not positive, is download mode the same as the bootloader on this device? If so, fastboot commands should work, and you can flash TWRP again, or do 'fastboot boot TWRP_filename' and it will boot TWRP temporarily.
Oh, and the factory reset just wipes your data, but otherwise doesn't restore your system to factory state. That's why your dpi change remained.

dude.. then what good is a factory reset?!? like seriously... and yeah, i tried that but i can't get adb to connect in download mode.. the device doesn't show up when I type "adb devices" like it did when i first rooted it. ... and i thought i followed the instructions exactly as it was laid out from this link.
http://forum.xda-developers.com/tmobile-lg-v10/general/guide-how-to-root-lg-v10-easy-t3274699
i think somewhere in there i must have missed something and ended up only booting into twrp temporarily.. which is certainly possible since i never boot to twrp during that initial process from the hardware keys or soft keys.. always through adb.. the phone was already plugged in.. typing the command was a couple keys away..
is there anyway to get TWRP on to the phone now? or am i screwed :'(
Well, it is a factory restore for the average user, because the average person isn't modifying their system. But no, I'm sure you're not screwed. If you're in the bootloader you can't use adb, you're already past that step, so you can skip to the fastboot part. What happens when you type fastboot devices? If the phone shows up then you can either fastboot flash or boot TWRP..

from what screen should i be attempting this? hold volume up with phone off and plug in to computer to enter download mode? should i try it at the factory reset screen (volume down plus power)? those are the only two screens i seem to have access to.. in download mode my pc/adb just doesn't recognize the phone.. it doesn't show up as a proper device like it did before this whole thing and in that factory reset mode i get nothing.. the download mode seems like its built for LG and runs from different drivers because in device manager it shows up with an error code that it couldn't start the device (this was not the case when i was using adb to unlock the bootloader and then using the bootloader to boot to TWRP..) what am i missing?
and hey, thank you so very much for taking time out of your day to help me. I really do appreciate it.

No problem buddy, and sorry for the confusion. You want to be on the bootloader screen, so here is what you can do: turn the phone off(or remove the battery if you have to, and put it back in), plug the usb cable into the computer only(not phone), hold volume down on phone, plug the usb cable into the phone. That should get you into the bootloader, and then you should be able to fastboot flash or fastboot boot TWRP.
Waiting for a resolution to this thread!
I'm pulling for you from the cheering section. (otherwise known as afraid to do it myself section!)
I'm pretty sure others have come through this exact situation unharmed (I've pretty much read every thread here.) so it's only a matter of time before you get this figured out.
Here's hoping it's sooner than later.
Sorry I can't offer more besides encouragement!

@ngoblirsch Along with the information provided in these suggestions and what you have said, you need to reinstall your LG/fastboot drivers on your PC while in fastboot mode

OH DEAR GOD THANK YOU!!!!
I spent all damn day yesterday trying to figure out how to get to the bootloader on this phone.. everything i read online said to hold volume down PLUS power while plugging it in and it was NOT working lmao. dude, thank you so much. after i read that comment here it took me about 30 seconds to connect to adb and boot to TWRP. This thread can be listed as RESOLVED!
Thanks again!! can't wait to start tweaking this awesome phone!

Well I appreciate the encouragement, it sure seems to have helped! Issue has been resolved. ended up that i just didn't know the hardware key combination to get to the bootloader/fastboot mode without being already connected to adb. nothing that i could find online said to hold volume down while plugging it in to a computer. as soon as i was able to do so i connected to adb and it was a breeze from there; I am now back with an OS AND a customer recovery properly installed on the device!! I will be hanging around these forums for as long as i have this phone so i'm sure i'll bump into you guys! absolutely love the community here on XDA, you guys are freaking awesome!!
