[Q] [HELP] P350 stuck on LG logo 4 softkeys blinking

Hi, I've just registered in this forum, though I've been reading you guys for almost a year. I just want to say that you guys are awesome, i've learned too much about android because of you.
Introduction
Said that, I recently had a problem with my P350g, I'll try to be as clear as possible hoping you can help me out.
The problem came after i installed CM 9 [stable 8] on it, at first it worked perfectly (a very few panics or reboots but i'm used to it :laugh. The next day after taking a photograph the cellphone got stuck, it had done that several times before with some other ROMs so i didn't pay much attention to it, so i took the battery off and put it again, and when I tried to turn it on, there it was, the lg logo with the 4 softkeys blinking.
-- It doesn't enter to recovery (i had recovery installed at that time) pressing [- power send] at the same time, it just stays there with the lg logo blinking.
-- It does enter to the emergency mode (yellow background with "emergency mode" in black letters) pressing [+ - power] at the same time.
-- It does enter to the fastboot mode pressing [+ power send] at the same time.
what i've already tryed:
--- i've read the wiki about this phone and try everything there (and everything found on google which is pretty much the same)
http://forum.xda-developers.com/wiki/LG_Optimus_Me
--- i've tryed using the KDZ updater as somebody on this forum recommended:
http://multidroid2.feed.nu/2012/03/27/how-to-unbrickflash-your-optimus-melg-p350-2/
using firmware from here:
http://lg-phone-firmware.com/index.php?id_mod=5
and from somewhere else on the internet, the problem here is, that when it comes to "restart the phone", it doesn't start, it just keeps getting stuck on the lg logo with the 4 softkeys blinking, after some time the KDZ updater shows an error: Upgrade Error WParam: 100 LParam: 6
--- i've tryed flashing the recovery from fastboot mode as shown on this thread:
http://forum.xda-developers.com/showthread.php?t=2131247
it flashes well, everything "succeeded" but whe it comes to reboot (flashboot reboot) the cellphone says on the screen rebooting cellphone (or something like that) but it never reboots. if I take the battery off and put it on again, and then try to turn it on, the cellphone shows at the same problem, the lg logo with 4 softkeys blinking.
--- I've also tryed this tool:
http://forum.xda-developers.com/showthread.php?t=1948326
it hasn't solved my problem either.
Computers' info
I've tried this on 2 computers:
windows 7 x86
windows 8 x64
both of them have the drivers installed, I've disabled the modem on both of them, both of them have the latest android SDK tools
both computers give me the same problems, please i need your help, i'm desperate, I've been with this problem for several days and I can't solve it. I hope you can help me out

bump!
Anybody? please, i'm desperate

Hi,
Let's hope for the good
Try to flash the rom with fastboot.
and did you overclocked it too high? maybe your nand is burned?

thanks for answering, yes i did overclock it really high ~804MHz can't remember the exact number, but with other roms it had been working at that level of overclock without any problems (besides the casual panics and reboots) for more than half a year.
i'm going to try flashing the rom from flashboot and see what happens

I couldn't fash a rom via fastboot

Hi everybody, i tried to flash a zip containing the rom on my p350, though i could not flash it. i used the command:
fastboot flash system rom.zip
but it says the file/rom size was smaller than expected. (honestly i can't remember the actual sentence) and then it says (x < y) where x is the suposed size of the rom and y is the expected size.
i tried with several roms, and a backup a user uploaded somewhere which was suposedly legitimate.
Is there something i can do?

download lg mobile support tool (lg mobile updater)
make sure that the driver is installed on the computer
open it
let it reconize the phone then
click recover phone from CS
the phone will be returned to latest stock rom for your country
then intsall recvoery again and root again

My Method
Well you need usb debugging enabled.Remove phone's batytery and connect it to pc via usb.It will boot up (horribly of course ignore it).Then fire up the kdz updater and start the flashing process.Once the phocess starts midway anywhere in the process insert the battery.The process will complete then KDZ will sat update complete...REBOOTING....and as battery is inserted it will reboot.Voila.Hope it works for you.This is my routine method.(Bricked more than 7 times lol).

Thanks for replying

thanks for the answer, I tried that way, though it keeps getting stuck in the LG logo with the 4 blinking softkeys when it comes to reboot the cellphone.

Nasty Bootloop after Flash on Sprint G2

Last night I installed geefree on my phone from the app store and used it to install TWRP. I downloaded a nightly CM11 and an appropriate gapps. Using geefree I rebooted to recovery (never figured out the button combination to boot to recovery "naturally") and installed both of the zips. This could be where I made my mistake, I installed both at the same time.
Now my phone loops, displaying the LG logo for a few seconds, then shutting off and rebooting before repeating the process. I can't seem to get it to go into download mode or the recovery menu. I've tried power+up, power+down, down+up and each of those while plugging the device in, etc. I can get the device to a hardware key control mode, though it doesn't seem too useful.
How can I save my phone? This forum has been a great resource in the past and I'm very grateful for the many tutorials I've followed rooting other devices. Hopefully you guys can save the day once again!

Volume up plus power is how to access recovery on sprint.
What stock sw version were you on before you flashed cm?
Did you wipe data before flashing?
Sent from my LG-LS970 using xda app-developers app

I was using stock 4.2.2, I believe. I didn't wipe the data (shame on me), a bad habit that I picked up from my first rooted device, the Samsung Moment. It didn't ever matter on that one, afaik. Thanks for the reply!
Edit: Volume up and power whether plugged in or not takes me to the hardware key control mode screen.
Second Edit: http://forum.xda-developers.com/showthread.php?t=2432476&page=35 I also found this thread where someone seems to be experiencing similar issues and they fix it with "LG Utility." Is that a PC application? It's a little vague to google, but I've been trying!

I have a bootloop issue every time i flash a rom i have to wipe all but sd flash roms and gapps the i do a restore from twrp and oly restore my boot image only and they boot no prob

I'm kind of starting to suspect my power button doesn't work at all for whatever reason. I have a lot of difficulty getting the phone to shut down, then it doesn't seem to easily power up. It's a strange collection of problems. Would a Sprint repair place be able to fix this?

If they have parts on hand if not either a swap out or a sendoff

Same problem here - bootloop and no download mode - CWM works! - urgently need help
I guess I have the same problem as InlineFourPower (apart from that my power-button has no problem).
I am stuck in bootloop since I tried to upgrade to Kitkat a few days ago. Now I can´t get into download mode any more, nor into fastboot or anything else. Only CWM works.
From within CWM I can successfully flash ROMs but that doesn´t help, since afterwards I am still stuck in bootloop. It is possible, however, to push files via adb-commands while I am in CWM.
Does anybody have an idea how to go from here or how to get download-mode back?

Device is recognized but can´t be mounted - bricked forever?

I tried a few things on Linux.
After terminal-command "ls /dev/sd*" when the device is unplugged from the computer I get "/dev/sda".
When the device is connected via USB, I get: "/dev/sda /dev/sdb"
So sdb is my LG G2.
So I went on to the next command: "gdisk -l /dev/sdb"
As a result I get: "Problem opening /dev/sdb for reading! Error is 123."
Does it mean that the phone isn´t mounted or what? Now I´ve connected my phone to another Linux machine with the same result. It is recognised (p.e. as sdd), but there is no sdd1. Seems as if it is recognized, but can´t be mounted. Does that mean my device is bricked for good? That´s it?

to get the phone into download mode you have to plug the usb cord in and hold VOL+, so to get this right as I have a case on mine, plug the usb into the phone first then hold VOL+ and plug into usb port on the computer.
it does take a loooong time to power down the phone with the button when stuck in a boot loop, just keep holding it until it shuts off, it will shut off eventually!!
plug the phone in while in download mode to install drivers and set com ports, then unplug before you begin your flash with LGFlashTool, hope this helps you out.

Thanks Cronic2009 for your advice.
There are, however, szenarios where download-mode is not accessible any more. Neither by using the hardware-keys, nor by using the adb-command.
After four days of resarch and a lot of trial and error, I finally unbricked my F320L using the two adb-commands outlined at the beginning of that thread: http://forum.xda-developers.com/showthread.php?t=2451696
Worked like a charm.
Thanks everyone for your advice.

no problem buddy, glad you got it figured out, good luck to you from here on out!
FYI, that link doesn't work
I just wanted to ask anyone who might know, since the bootloader of the LS980 is locked, we cannot "break" this correct, so no matter what commands we decide to run through root, we cant touch the true bootloader there for LS980 fail safe? (Besides Acts of God, EMP, ect)

Thanks for letting me know. I corrected the link in my previous post.

Be sure if you use a aosp based rom to flash the ZV8 modem. Your can use dr87 or furnance kernals after you flash the zva modem althought i have encountered soft brick due to this.

so i'm having this exact issue and i don't know how to get out of it. i just need to transfer the radio to my phone somehow but nothing shows up under adb devices. i'm trying to the lg mobile support tool now. its downloading the software. but if it doesn't work does any one have any fixes?

After using tot and flash tool to get back to stock, did you try going into stock recovery and do a factory data reset? I know it sounds stupid especially after a tot but try it. Couldn't hurt

Borderline noob here, so please bear with me...
I have been using TWRP 2.7.0.0 to do all my work, and I was able to get the Lego ROM installed with ZVA. I got into too big of a hurry and forgot to make a backup of stock. I've also been unsuccessful in trying to install ZVC modem and firmware. Thankfully ZVA works as does the LEGO ROM, but I'd like to have stock there to access as well. The stockZVC that's on the Android Development page has been getting stuck (bootloop?) on the Sprint Spark logo. I've done TWRP's factory reset with no success. Any help would be great.
Thanks in advance!

Yes sir I've tried that and more to no avail is there anything I can do through adb I'm on stock recovery phone doesn't stay on long enough to install anything

Thanks again.
OBS: I have used that app too before get this error. And was just becouse tryed to enter on recovery mode that i got that message.

Well, i'll try to explain all to not get missunderstood.
My situation is, without the USB cable the celphone don't respond to any button press.
With USB cable, by the momment that i plug it, the screen shows the error message.
With the USB cable and in the error message screen, i can press the volume buttons +- and power, after that the phone restart and shows the download mode.
What i know so far is, if i can enter download mode, and here is your words, all is not lost.
Knowing that, all solutions i found on this site doesn't work with me. Or, what is possible, i didn't make it right.
The phone do not enter on recovery mode.
I gess this is all. For now

I recommend U to uninstall all LG stuff from your PC and follow this guide: http://www.htcmania.com/forumdisplay.php?f=1026

I did it yestesrday and save me. Whit it U will install a new KDZ firmware, even if it is bigger than 1GB
Good luck

As I see, if i'm looking for the guide you are refering, of install the original rom, is the same one that i already tried and i got message error of extract file.
I deleted all lg stuff from computer, downloaded everything of the guide and the message is the same.
Any more suggestion ?
PS: I prefer english version , at least to read is easy to me.
Edit1:I wonder if the fact of my kdz file be bigger than 1gb causes that ?
Edit2: When i try the guide on this link the step 7 does not show to me, and my phone or some similar does not show on the Usb Controler list to install.
Thanks again

Now I am really worried about that. I just can't acces the phone by any kind of way.
When i try the Unlock Botloader, it says that didn't found my device.
Now, after restart the computer, it says: The system cannot find the patch specified.
Is there no more options for me ?
The drivers I have downloaded here was automaticly updated from 8.0xx to 10.0xx, I unterstand this is a good thing, am I wrong ?

Could U flash KDZ using the method from htc mania?? (Im using it rigth now with 1.2GB KDZ firmware)
How did U come to that situation?

What about my edit, where i found that someone said it solve the problem on 15%, do you think it could work ?
I just don't understant well, do I need to be able to start my phone rom ? Or i can do on my situation ?
Hello guys,
I am so happy that I wanted to share this with you. As I still have headache from googling how to flash back your stock rom (which didn't work out because the flash tool gave an error every time at 15%), I can save you a lot of headache with this very very simple fix.
For some people the tool works just fine, but when you have some google bootloader or a newer freegee unlocked one and you want back to stock, lots of people cant follow this thread because of the error at 15%.
The fix is EASY and I found it on the Optimus L9 section, thanks to that guy on XDA.
Follow exactly Davevinci's great thread except for one thing:
http://forum.xda-developers.com/show....php?t=2498102
Step 4 is now:
4.GO TO DOWNLOAD MODE POW+BOTH VOL BUTTON PRESSED+CONNECT USB
But step 4 should be:
- Boot up your phone in any stock based rom, for example SAVVY Rom V5
- Enable USB debugging and connect your phone through USB using the LG PC Suite option (make sure to kill PC suite in tast manager).
Now you should see the driver installation of LGE Android MTP device as usual and then just run the flash tool from the guide. Also de mode DIAG is now the right one. The flashtool will reboot your phone to download mode automatically when it's needed.
Still an error? Don't worry, disable virus scanner and firewall and just reconnect your phone. I got an error one time, during flashing, but I followed the steps the flashtool suggested me and now everything went fine.

The link U provide is not working and U didnt upload any log, I didnt see it.
As I read to perform that action u must be able to turn on your phone.
Did U try to flash a smaller then 1gb kdz or try another ones.
As U can see U wont receive to much help in LG forum. There are good guides but on time help is another thing.
Did U try this guide (method 1): http://forum.xda-developers.com/showthread.php?t=2667398
Is your phone properly detected in your PC?

I did not tried with a smaller archive because I can't download it. Among the Brazilian files I only can download the version 10D. I am on phone now but I will send the link that I'm trying asap. I really appreciate your help man. Even that I didn't found the solution yet is nice count with some experience help.

Edit: From this list http://forum.xda-developers.com/showthread.php?t=2093382 , all brazilian links show Access Denied
And from here http://lg-phone-firmware.com/index.php?id_mod=20, only the V10D of Brazil.
I'm looking for the number 16, CLR/CLARO(BRAZIL) which is less than 1GB. Maybe i'm wrong, but when i clic on the name, a page of TNY shows a link of ADFLY that after i clic on close advertisement nothing happen.
About the method 1, I did try that, but sometimes it says "device not found" or "the system cannot find the patch specified". I'll try that from another computer, i let you know if i have some lucky. But the guy of the guide said:
!enable usb debugging
connect as MTP
follow the script"
Maybe its not for me.
Look what happen. (I'm using download mode)

[q] extreme help requested -- please

I have a Korea F400L in which i had installed Sphynx rom.
after reading for a few weeks I decided to install the proper version of cloudy g3 1.2, which booted rather normally.
after asking a few questions about overclocking i got a few recommendations about the F400-RIN 1.7,
so I flash this kernel and somehow i lost EVERYTHING.
now when i boot, i get a GREEN SCREEN WITH THE FOLLOWING
DemiGod Crash Handler : Apps watchdog bark !
Press key to choose Dload Mode or Reboot
1) volume Up : Dload Mode
2) Volume Down : Reboot
If you choose Dload Mode
Please do following action
1) Dload Mode, Please connect USB
2) Get the ram dump image using QPST Configuration
Board Info - rev : 1..1 speed, pvs : 3.5 serial : 09b66e1b60e36d28
The model number used in this country is the D851 so help for the F400 does not exist.

THANK YOU AND HOPE TO FIND THE PROPER SOLUTION

Just reboot into recovery and restore a backup. To get into recovery, power off phone. Then press power and volume down, when you see LG screen release buttons and then press and hold power and volume down again.

As p70shooter already sad, you can go to custom recovery.. After you enter custom recovery, if you don't have backup, connection with PC will work and you can upload some new ROM and flash it.

let me know if you can manage this on your own otherwise happy to get on skype with you and talk u through

not good
I can't go into recovery at all
at best i can go into download, flashtool starts "sometimes" it will reach 2% sometimes it will reach 4% then ALWAYS it will tell me phone unplugged try again.
Also at the green screen with the big message I posted before, if i push volume up with the flash tool it ALSO will say starting upload and ALSO dies at 4%
don't know what else, i have a tot file, i will see if i can use it instead of the kdz
please some one, on top of this, i buy another g3 on monday and the jerk hasn't shipped and i guess he thinks he's gone with my money, too bad he
doesn't know that paypal is kinda nasty with thieves, i know i'll get my money back but do i need the hassle,
thanks for anyone's help

I want to root my ZE551ML but I don't know what to do pls help.

I tried to root my phone last night, but I stop midway of the process because of some problems like "phone not turning on with no vibrate at all when I restart after its stuck to inverted white screen, when I luckily turn it back on but it bootloops".
Heres the details:
I run unlock.bat then after its done it reboots with inverted white screen with logo then I run restore.bat and after it restart there is no sign of warning "failed verification" until it fully loads up, I go back to fastboot again to flash TWRP after running twrp.bat it says "flash succesfully" and the program closed by itself, then I go to recovery mode after rebooting I saw android error just like how it use to be. I press power button + volume up then release the volume up then I see the stock recovery (which it should be TWRP since I've done flashing it).
I think that my bootloader is still locked since there's no warning display of "failed verification". So I repeat the steps again after running unlock.bat, it reboots and the screen is inverted but it's stuck up to white logo, I waited for a while but nothing happens so I tried to reboot my phone "holding power button (power off)" when power on, it wont turn on, no vibration just a sound on laptop "connected sound and disconnected sound" I tried to power it on many times but still no luck I got panicked, jittery walking back and forth :crying:. Then I disconnect the usb cable and I tried to turn it on and suddenly I feel the vibration on my phone then it boots up but still stuck in white screen then it restart after keeping it for too long (while watching videos related to my problem)...
then my friend here said "ohh it bootloop" he read the instruction and he said to try this
"FAQ 1. Stuck at white screen with asus logo?
Sol. a) White screen means you are unlocked (action of unlock.bat), so you may give a try to restore.bat in fastboot mode."
and it solve my problem my phone is working again ... But I want to continue to root it but I'm afraid which steps I should go next, I still don't see the warning "failed verification" after my phone boots up and works again... I need HELP thank you
I also got question: is my bootloader unlock since it inverted white screen? or it still locked since there no sign of warning "failed verification"?

@PrinceLys
What is your build number in settings ,about phone ?

ahmm I think this?
model number: ASUS_Z00AD
android version: 6.0.1
software information: WW_4.21.40.223_20161216
P.S my phone is back on working state.
I just don't know if I can proceed to root after the incident. I don't know, I just want to make sure that my bootloader is still unlocked after what I've done (it did white screen with black asus logo) or.... it doesn't unlocked at all since I don't see this warning "your device has failed verification and may not work properly." (I've attach screenshot from the video tutorial)
I tried to manualy check if my bootloader is really on unlock state but I can't using these methods
method 1: on device’s dialer dial *#*#7378423#*#* (failed)
method 2: fastboot oem device-info (failed)
my recovery it still on stock recovery even after I flash twrp
btw guide source: https://forum.xda-developers.com/zenfone2/general/root-install-xposed-marshmallow-6-0-1-t3456443
Q: should I still continue to flash twrp until it install?

Theres 2 bootloader unlock tools in general section , one is automatic

Read this from start to finish before doing anything.. also have on another device to refer to as you are doing the steps also download the ROM and gapps you want and put on SD card before you start even if you have to download them and move them from PC to SD card. https://plus.google.com/113955136844726294013/posts/aLJdNZN3g8q

I've haven't fully read the instruction maybe tomorrow I will read it.
I just downloaded the files early and look into it... it seems like the versions are kinda latest (I don't know much about the droidboot ver. but I just look at the number on it "the higher the latest /heh") also the twrp is 3.0.3.
the ones that I used are all in package and it was 3.0.2 so I kinda go for the link you gave me
Thanks :good:

Hi,I've had the same situation,but it is solved now.If you have any problem,maybe I can help you .
