Big Problem [LG L90 D405n] - LG Optimus L90

Hi everyone,
Shows up an official update on phone of my girlfriend, and after downloaded the update, the phone reboots and shows CWM.
It doesn't appears the package for installation of update. What I need to to for I install the update?
I try turn on the phone but I can't because the phone restarts and shows CWM.
What I need to do?!
I start the phone, I reboot the phone, always show CWM. The phone can't plug by USB to computer... I have a phone bricked??!?!

Please, anyone to help?

hello,
is the same thing happened to me yesterday.
You can download the USB drivers from the LG site and install without plug the phone.
Then off the phone, plug phone via usb on pc and turn on it by holding the volume -, it start in download mode.
Then with lg support tool you can do the update online and install it on the phone.
After this update, however, you lose the root and cwm,
I'm trying to find on xda how to root again with v10d....
sorry for my english....

Here also a problem, can't pass twrp... Can't restore any update...
I removed battery, connect with usb cable & hold volume + (if you have installed and opened LG Mobile Support Tool), it will go to download mode and you can reinstal software.
(I edit post if I have more info)
Bingo!! New software version, 10d, no twrp or root
Root and unlock again, flash twrp again -> also be able to restore old back ups (removed original LG back up, so now on new software LG)

Yes, sorry... it was VolumeUp for starting in download mode...
The good news is that root for me works with this guide!!!

Root is also working for me, I also was be able to unlock the bootloader with about.bin for v10b. After that I reflashed twrp and could use my old back up (deleted my old LG back up!).
Sent from my K00F using XDA Free mobile app

I did what you said, and... It works! Thanks a lot. my girlfriend doesn't want root and bootloader unlocked.
She say that software is different..

[Q] Only bootloop and sw update mode

I bought a Optimus Black and i wanted to delete old account, so i reseted all phone options in settings. After that phone turned off for 5 seconds and turned on with LG logo and flashing keys. And it's not end. The only thing i can do is turn to SW Uptade Mode, when i pushing Volume up button and connect with USB to my computer. SmartFlashTool didn't work, B2CAppSetup.exe don't want install. Can I do anything else? Is it BootLoader broken?
i dont know what is B2CAppSetup.exe but if you want to run smart flash, you should install usb drivers first.
Look this page for drivers. http://www.lg.com/tr/telefon-destegi/lg-P970-LG-Optimus-Black
sorry, B2CAppSetup.exe is LGMobile Support Tool. I have USB drivers, and Smart Flash worked corretly (i think, there is a text on green background "... completed" at the end), but phone reseted and still have a bootloop.
you flashed cwm integrated bin file?
if so, after opening cwm, did you make wipe data?
if you didnt, it will bootlop
I did everything according to the tutorial http://forum.xda-developers.com/showthread.php?t=1448803 and i can't open the cmw.
try this
it is cwm integrated bin and fls files
flash with smart flash tool
after flash, cwm opens automaticaly
after that choose wipe data
and reboot phone
file:

If it still doesn't work after flashing with Smart Flash Tool then take it into repair shop. It's a hardware problem.

Wait...
You just rooted, but didn't unlock the bootloader? If you want to install CWM on this device you HAVE to unlock the bootloader first!
And do you see the 1st bootlogo (not moving one) or the 2nd bootlogo (this logo is moving)?
Try to pull out your battery for at least 10 seconds, then plug it in again and start flashing a new KDZ, I guess there will be no other way, since the recovery will be corrupt...
Do you see two red lines at top . If so your bootloader is locked and don't allow cwm recovery to work Try use power + vol up while phone connected to pc it should get you to so called recovery mode from there try reboot and it should work then you have to unlock bootloader to get cwm recovery to work
Another thing I didn't try myself but installing cwm recovery is replacing file dev/block/mmcblk0p1
Maybe if you have the original file copy it over there return you back to stock recovery

Many Problems with installing Cyanogenmod on LG Optimus 4X HD...

Hello everybody,
so I'm as new to this forum as I am to the android world. Just this Wednesday i bought a new LG Optimus 4X HD on amazon.de
Thought it would be nice to start of with Cyanogenmod.
So I started my search for some good "How-To's"...it were many I went through and I already invested many hours in getting this running. Sadly it still doesn't work. I actually wanted to stay with one How-To but at one point there's always a download not working so that other sources are needed.
So what did I do...
-I rooted it yes (at this point I needed to download "Rooting Toolkit for Optimus 4X HD" which wasn't downloadable so i switched to another How-To, btw. first How-To: http://androidlegend.com/android-4-2-1-via-cyanogenmod-10-1-for-lg-optimus-4x-hd-p880-cm10-1/
-Installed "LG 4X Recovery 1.2" and installed this way CWM.
-At another point here I installed ROM Manager, installed it and went into Recovery and here happend the first problem, kernel panic.
Said something like "couldn't load kernel/wrong kernel", kernel panics...Me panics too
Anyway, force kill -> auto reboot -> still kernel panic -> again -> batterie out and a few times with usb cable connected to PC -> Batterie again, works :good:
Ok so Clockworkmods Rom Manager seemed to be not that good... did recovery boot with LG 4X Recovery, tada works, I go into the folder with the Cyanogenmod-zip and want to start the ROM installation and it says Status 7 (of course I googled Status 7 and searched here in the xda-boards for it, nothing helpful found yet)
Installed older version of LG 4X Recovery (1.1), still same fault.
I uninstall the ROM manager, redownload and reinstall, try to backup -> Kernel panic.
I search for a different How-To, yet nothing good happened. Others go something similar and say "at booting press On-Button and Volume down-button at the same time", I do that -> Kernel panic
I have no idea whats wrong with the kernel...but normal booting works fine.
Next I read something about needing to unlock bootloader, have a workthrough aka this http://forum.xda-developers.com/showthread.php?t=2224020
After I enter "adb reboot oem-unlock" in DOS command window it should say something concerning "open bootloader", but not in my case, just a normal reboot happened (this is what it looks like at least). Checking the hidden menu also doesn't show anything as I don't have the option with the boot-loader status there.
Next trick, I go to LG Recovery again and first wipe the whole stuff and try then the Cyanogen istall, still doesn't work and as I wasn't able to backups before (tried Titanium but it froze at 12% and the stuff about ROM Manager is told^^) I now had a clean factory install, all my work before lost, nothing rooted and still a kernel which panics when I do the "safe-boot"(this volume- and on-button-thing).
I also tried 3-All-in-one solutions, neither of them worked. (2 german ones, and one english one)
So I think thats it, ah wrong, still not finished. I also tried to install a new kernel to erase that f****ng problem with the kernel panic. I choose to use WerwewolfJB_v005 http://forum.xda-developers.com/showthread.php?t=2256899
the easy and fast way made the same as the try before with the "open bootloader"-try, just normal restart. When I enter the second line in the command line, it just says "waiting for device".
So yeah, thats it. I don't know what else to do. Does anyone know what I could also do, or is this case unsolvable? Is the Smartphone broken or did I make a mistake at any point? What should I do?
I'd be super glad if anyone could help me here. I hope I described my case well enough. I hope I didn't forget anything.
Thanks in advance!

I am also new to this stuff but maybe i could help you anyway
What is the Firmware Version of your phone?
(Sorry for bad english )
The old "adb reboot oem-unlock" didn't work for me on UK, v234-000 either. I followed this thread instead and it worked perfectly first time.
As long as your phone has been turned on and connected to the network for long enough on v20x you should be fine - once you get the notification from LG about your phone being registered or similar then you'll be fine, normally a couple of hours.
Just reflash your phone to stock, wait for the notification and try the two-step method from the above post and you should be fine.
root , recorery and unlock boot loader
you must have your bootloader unlocked in order to flash kernels
( this worked for me but I can't guarantee it will work for others you can only try !! be aware when messing with firmware and bootloader you warranty could be voided )
make sure your phone is rooted you know if it is rooted because you will have superuser installed in your apps ( grey square icon with green android head on it ). if not I used this method to root my phone so try this http://forum.xda-developers.com/showthread.php?t=2180688
if your phone is rooted next you will need a recovery this will help to backup your phone and create a restore point so in case any thing goes wrong. to install a recovery go to play store and download rom manager ( clockworkmod ) once installed open rom manger and select recovery setup. then select install or update recovery then select your phone ( lg optimus 4x hd). then select flash clockworkmod recovery. and then wait while it downloads and setup . hopefully when finished it will say succesfull. ( make sure phone is rooted or it wont work ) to check clockwork mod is working you can reboot into recovery through rom manager or power off phone then hold volume down key press power button to power up but keep holding volume down key until recovery boot up. ( be a wise option to backup phone now in recovery)
next to unlock bootloader ( so you can flash roms with kernels) go to this thread, http://forum.xda-developers.com/showthread.php?t=2224020
and download the BL_unlock_new .rar file when its download copy it to your desktop on pc and then extract it to desktop on pc . now make sure your phone is not connected to your computer go to phone settings,then go to development options, and then select usb debugging on. once debugging is on now connect your phone to pc wait for it to connect you can keep your phone on charging mode. now open the BL_unlocking_new extracted folder on desktop on pc and double click on the BL_unlock file a box should open up on your desktop asking you to tap a key to continue so press a key now your phone should reboot and some white writing will appear on screen .on your desktop the bottom line should say please... now tap a key on computer it should say press any key to continue < waiting for device> now disconnect phone from computer look on phone screen it should say now ready! now hold power button for 10 secs and let phone reboot. to test if bootloader is unlocked on phone go to dail pad and dail this 3845#*880# you should get the hidden menu on your screen scroll down to bootloader unlock check and select then select bootloader unlock check and hopefully it should say unlock...
now you have root , recovery and bootloader unlock, now you can download a rom for this phone copy rom ( should be a zip file ) to your phone then open rom manager on phone and reboot in to recovery or power off phone, hold volume down button then press power button should now boot into recovery then you want to use volume keys to scroll down and select wipe data/factory reset with power button then scroll down and select advanced then scroll down and select wipe dalvik cache then you want to select go back then select install zip from sd card then select where you saved your rom sd card or external sd card then select rom then select install...
hopefully if that's helped you or anybody else ...

If the OP can possibly get his bootloader unlocked following the official method then he should, rather than using that file. Nobody really knows what all the 'fuses' that are blown by using that file do and that would certainly result in his warranty being voided in any country, whereas in a lot of countries his warranty won't actually be voided by using the official unlock method.

edited last post with a warning you could void warranty !!
Ok, thanks for the answers so far. But still, wasn't able to get any further.
@Dexxon: Firmware version is 4.0.3
Besides: Kernel Version is 2.6.39.4 and there's also something written like "[email protected] #1" in the hidden menu...is this normal? AP Bootloader Verison unknown and AP OS Version is 2.6.39.4 also this jinwoo...
@SimonTS: I tried to unlock the bootloader with your link and advices (which is the same as i tried before).
Got a message saying "Thanks for buying this LG Phone..blabla" and I guess thats what you mentantioned about that informing.
Battery was loaded to 100% so i connected it to PC, said "LG Software Mode Connection" on the phone (before I always took that "data exchange connection"), went to the adb folder and made a command window there, entered "adb reboot-bootloader", smartphone reboots, should stay in LG window screen, but it doesn't. It just boots totally normal into the home screen.
@Hursty uk: As I said in the first post. Everything regarding the ROM Manager from CWM sends my Phone into kernel panic. As this is quite hard to get a normal reboot again (even battery out for some time and back-in doesn't solve this) I really prefere to not use this option. As it is just frustrating and doesn't help.
And yes it is already rooted (I have SuperSU and I checked it with the "Root Checker"-App) Everything says it is rooted. I rooted it with that method: androidlegend.com/how-to-root-lg-optimus-4x-hd-o4x-p880
Ah I really don't know what else to do. Is something just wrong with my device?
btw I also can't do a software update with the LG Software from there website, so I could at least go 4.1 instead of 4.0.3 atm...
When I try it that way, and install the USB-Drvier for LG P880 the SW-Update button stays grey and is unclickable even though the phone is connected.

To unlock the bootloader following either of the official methods requires you to be running v20x (The LG Stock v4.1 code) first, so that is why the commands are doing nothing for you.
For the moment, forget about CWM, Root, Bootloaders etc - the key thing is to get your phone working again. Can you reinstall stock v10x software following the guide on this page?

He might as well just flash JB with flashtool, saves him flashing ICS just to flash JB straight after

that would of been my next answer @SimonTS . A while back a flashed something on my phone and it got stuck at the lg bootup picture what I had to do was re-install original firmware ( through KDZ files) to get my phone working. I would try the link @SimonTS suggested .

Indeed - sorry, having a slightly dense day and was more thinking about getting him back to the stage at which his phone was working correctly before.

Thanks for that link, I tried it but that also didn't work (at least I guess so...)
I did everything like said at the link but at the last point the program (kdz_fw_upd.exe) crashes. Tried it 3 times, every time as administrator like mentioned in that forum post. I'm using Win 8 64bit btw...
Screenshot is in the attached .jpg. My system is japanese, but I think you can figure out what this kind of window means. It just says that the program isn't responding and needs to be shutdown.
I tried it like mentioned with putting the battery back in when the log starts and without putting it back in, in both cases the program crashes after a few seconds (~10 secs) when started.
Where do I actually see which V**x version is installed? If v10x or v20a? Surprisingly the LG Support Tool said I have v10H when the phone was still connected after the crash. And it offered me a SW-Update. But I haven't done that one yet, not sure if that would work correct...

+1 this. Also, there have been many problems with running these apps using Windows 8, and you need to make sure you're not using a USB 3 port as they being other problems in to the equation.

Ok so I've flashed JB with the LG Updater (without batterie and volume down button pressed connecting to PC, than start the update -> meanwhile putting batterie back in)
JB worked just fine and I also don't had the problem with the kernel panic when booting with volume down and power button.
So I thought, everything fresh and also different, I might give the ROM Manager App again a try (after I rooted it that way: http://forum.xda-developers.com/showthread.php?t=2180688 )...well, wasn't that smart. After I installed the Recovery for P880 in the ROM Manager, i made a normal boot (just for sure), back in the app, i wanted to go into Recovery mode and again kernel panic, bit different this time cause it does a shutdown after 5 seconds^^
Anyway, this way it didn't work, from now on I also couldn't go into safe mode anymore, same kernel panic.
As this kind of recovery doesn't seem to work, I tried the "old" way with the "LG 4X Recovery" I mentioned before. After recovery installation i just wanted to boot normal aaaand nothing happened. It stayed in the LG screen. Restart and anything didn't help here so I backed back to v10H with previous methods. Now I just got a security error saying "morning call is empty", no idea what that means but I just did the same method for JB again.
Worked afterwards, so I wanted to try it without ROM Manager Recovery installed and just LG 4X Recovery, (after rooted again of course) and it didn't boot again. Same game again.
So now I have JB installed, I'm going to root it now again, but I don't know what way I should go for doing the Recovery Part. I'm stuck on point 3 here
Any advices? btw thanks a lot until here, at least I made it half-way-through to JB now. Worst case I'd stay with that one at least.
I'm not entirely sure which threads you've been reading. Once you have the stock v20x ROM on your phone, just leave it alone for a few hours and make sure it is fully charged
After that, try to unlock the bootloader before doing anything else. If that works then you can worry about CWM and custom ROMs.

Ok so I've flashed JB with the LG Updater (without batterie and volume down button pressed connecting to PC, than start the update -> meanwhile putting batterie back in)
JB worked just fine and I also don't had the problem with the kernel panic when booting with volume down and power button.
So I thought, everything fresh and also different, I might give the ROM Manager App again a try (after I rooted it that way: http://forum.xda-developers.com/showthread.php?t=2180688 )...well, wasn't that smart. After I installed the Recovery for P880 in the ROM Manager, i made a normal boot (just for sure), back in the app, i wanted to go into Recovery mode and again kernel panic, bit different this time cause it does a shutdown after 5 seconds^^
Anyway, this way it didn't work, from now on I also couldn't go into safe mode anymore, same kernel panic.
As this kind of recovery doesn't seem to work, I tried the "old" way with the "LG 4X Recovery" I mentioned before. After recovery installation i just wanted to boot normal aaaand nothing happened. It stayed in the LG screen. Restart and anything didn't help here so I backed back to v10H with previous methods. Now I just got a security error saying "morning call is empty", no idea what that means but I just did the same method for JB again.
Worked afterwards, so I wanted to try it without ROM Manager Recovery installed and just LG 4X Recovery, (after rooted again of course) and it didn't boot again. Same game again.
So now I have JB installed, I'm going to root it now again, but I don't know what way I should go for doing the Recovery Part. I'm stuck on point 3 here
Any advices? btw thanks a lot until here, at least I made it half-way-through to JB now. Worst case I'd stay with that one at least.

ok.
now i suppose you have a functional rooted JB 4.1.2 device.
from that you have to going on to rest of the steps to have CM installed on your device.so if it is not that (functional rooted JB device) is need to flash again JB and rooted again.
if you have the proper kdz file the tutorial for flasing is there: http://forum.xda-developers.com/showthread.php?t=2069723
and the tutorial for rooting device is there: http://forum.xda-developers.com/showthread.php?t=2180688&highlight=root+jb+4+1+2+
after that make some reboot of device to verify that:
1. the device boot to system normaly a few times (just let the device boot itself)
2. the device enter in S/W Upgrade Mode (with the device off, put the USB cable in device and PC or in device and AC adapter and press VOL DOWN + POWER) a few times
3. the device boot in Stock Recovery (with the device off, press VOL DOWN + POWER) a few time.
if you can manage to do this tree steps a few times normaly then you have a fully functional device and we go to next step that is Custom Recovery
the chance to make this steps without errors is more big if you start from scratch meaning fully wipe the device and flashing stock LG software on the device.
so, let as know here when you are ready...

he should unlock bootloader before flashing custom recovery.
so, dont use rom manager before you unlock bootloader, that's why you get kernel panics.

You are far, far from the first person to ask that question so please put some effort in and search first, rather than simply expecting people to repeat the same instructions for the 100th time.

error boot image signature means the bootloader is locked. so u didnt install the recovery and so thats why u cant go in recovery. u just deleted the stock recovery by mistake. now u either go ahead and try unlock , flash recovery and install new rom if u want to go away from stock rom, or use kdz to restore.
<<EDIT>> i dont understand that o4x. i just told you whats ur situation there. now use search and find the solution
Hi there,
I was recently put in the same situation, i.e. I installed ROM Manager and then ClockworkMod. When I open ROM Manager --> Recovery Setup --> Install or Update Recovery --> Click on "ClockworkMod Recovery" --> I get "Error while downloading from server. Please make sure that you have a stable internet connection and that your SD card is inserted and have free space!". I have made sure that I have both, therefore I do not understand why I get this error. When I select "Reboot into recovery" in ROM Manager my phone restarts and then I get the same error as ruznik.
When I try to boot into recovery manually, i.e. switch off phone, Volume UP (or DOWN) + Power button, I get the same error as ruznik. However, my phone boots normally which is always a relief.
I uninstalled ROM Manager and tried to boot into recovery and I got the same error as ruznik. Then I installed back ROM Manager and in the Recovery set up there is already "ClockworkMod recovery", which probably means that ClockworkMod was not uninstalled when I uninstalled ROM Manager.
I have rooted my LG P880, but I believe I have not unlocked the bootloader (I suspect that CWM + bootloader not unlocked is what is causing the error with booting into recovery?). I say I believe, because I did the rooting some time ago and I do not remember if I have unlocked the bootloader as well.
I would like to uninstall CMW. However, I understand that this is not a very easy thing, therefore I would be happy to reflash my EUR-XXX Jelly Bean 4.1.2, root and then unlock the bootloader. However, although I have properly installed the drivers (as this is not the first time I will flash the EUR-XXX), my phone does not connect to my PC, although it charges from the PC. I have tried with two different cables, I have enabled debugging, I have Media Sync enabled (I tried also the option LG software as I have LG PC suite installed), I have tried to connect it to different ports, I have tried to connect it to different PCs, but still nothing. Note that this is happening only with my LG P880, because I can connect properly my Iphone 4S to all 3 PCs. Also, when I open my LG PC suite, I cannot connect the mobile phone to the LG PC suite via cable, but I can connect it via Wifi connection.
I am a bit reluctant to unlock the bootloader, e.g.
youtubedotcomslashwatch?v=sBeirPeT2rQ
youtubedotcomslashwatch?v=iqEop-ThNug
because I do not want to brick my working phone when I cannot connect it to my PC so that I can flash it (sorry for the broken links - I am not allowed to post links because I am new to XDA). Therefore, I have two questions:
1) Is there anything I can do to connect my phone to a PC? I believe that everything went wrong after I installed ROM Manager and then CWM via ROM Manager.
2) Is it safe to unlock the bootloader while the phone is in the current state? I am not sure if the phone will restart and then will not be able to turn on again because it will be bricked? And since I have not managed to connect my phone to a PC, I am not sure how I will be able to flash the software?
Apologies for long email - I tried to be as descriptive as I can. Thank you in advance for any suggestions.

i dont know flash kdz ( ithink my device got bricked)

Once you have the cwm power+volume down press together and wait till cwm shows up. Then you can use as you probably planned to do with onlocking and flashing cwm.
On your pc you can download rom and transfer via usb /mount usb or smth like that
Then follow instructions of rom devs to install.
If that doesn't seem to work, you should force an update through the LGMobile Support Tool. Then start over again. You probably didn't unlock your bootloader properly (you can check it in the hidden menu or in S/W Upgrade mode), or you flashed a wrong recovery.. Good luck
