turn on your phone and goto recovery
connect your phone to pc
open command prompt and run adb (if you you dont know how to setup/use adb Google it)
type in following commands
adb shell
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc bs=1 count=1088

Cheers man!! I thought it was the codes on the bottom of the post haha..

so i shouldnt have any problems now right?

Need help again
I flashed this ROM last night, and im liking it. But today my service keeps dropping. But if i go through the settings to search for networks, it appears. I also tried to flash my modem again and still had problems. Should i try to use a different modem? btw, i extracted this modem from stock and i never had a problem with this modem with stock rom. It doesnt really matter for me but i would still like to know the fix to this

I have had this same issue whenever I hard book into recovery (volume up + power). I've tested it with cwm that's installed via freegee, and philz touch. Both go into a boot loop whenever recovery is entered via a hard boot. Things work fine if I reboot to recovery from freegee.
I just restored back to factory via LGflash install. . . several times now
Really need to find a solution I can hardboot into recovery with and get out of. . .

use madmac's lokified twrp
for anyone who's still following this and/or having this issue with CWM going into a recovery loop when entered form power off, use madmac's lokified TWRP. . . zip linked:
madmac's lokified twrp

Got another problem sadly... My signal keeps dropping whenever my screen is on, but when it is off, it stays at 4bars. This morning my phone was hot and off (literally) due to the modem searching for signal crazy (i asked some people why this happend and they said it was the modem not the rom that i particular have right now) but anyway.. I cant find a suitable modem for me since this phone isnt available in Australia. So what should i do?? I dont want to wake up in the morning with a hot phone and lose around 20% battery... Please help me out :/

HARD BRICKED? Wont power on no download mode

From bricking this pos I have learned a lot of what to do and what not to do. I am pretty sure but need to know for certain...is there a fix for this?
Like many others I tried to install cwm recovery from android terminal emulator and sounds like I either put the image in the wrong spot or tried to install over something important. Odin doesnt work on this phone and rom manager just kept giving me the messaging has stopped working error, I soft bricked once before this but was able to flash and fix. I installed cwm recovery from rom manager I thought but was not able to boot in recovery. Ive read tons of posts and tried all the little tricks. No download mode, never could boot in recovery, had to install the qhsusb_dload drivers and now when connected to pc its a 50/50 chance of either good connect sound or bad connect sound...either way the phone doesnt power on at all. Can someone help me or should I sell this to someone who can make use of it? I have flashed and rooted many phones in the past and used to come here regularly, this has always been the BEST site for answers and help so Im really hoping you tech devs can pull through for me on this one. Any help is appreciated!
What do you mean ROM manager stops working if your phone is hard bricked.
I'm not surprised Odin doesn't work I thought that was for Samsung phones but I've never used it.
Anyways I understand you think you might have used the adb shell and copied the cwm recovery to the wrong partition do you remember which it could have been?
boot.img at mmcblk0p8
recovery.img at mmcblk0p13
firmware.img at mmcblk0p1
baseband.img at mmcblk0p14
system.img at mmcblk0p27
Also I'm sure its been said but make sure you have a decent charge leave it plugged into the wall for at least an hour without trying anything.
I just am curious you don't see lg logo? battery animation? anything?

thanks for replying. i have tried switching batteries, waited overnight, tried everything i could find on here and no power no logo no start up whatsoever. i was getting so desperate to get cwm recovery to work that i probably followed directions i shouldnt have. i followed a youtube vid and typed the following into the terminal;
su
dd if=/dev/block/mmcblk0p6 of=/sdcard/mmcblk0p6.backup bs=4096
dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p6 bs=4096
dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p6 bs=4096
after this i powered off the phone and it never came back to life since. the problem with rom manager was it wouldnt update cwm recovery, even though i just installed it the night before, the next day there was a new update it said. every time i tried to install a rom from rom manager it force closed and said messaging has stopped working. (what messaging had to do with it i dont know) when i plugged in my phone to pc it said couldnt find qhsusb_dload drivers so i installed them and now my phone doesnt show up on my pc. i read somewhere to try lgtools but that comes with its own problems like smartcard driver errors. i hope this is enough info thanks

When you ran the command "dd if=/dev/block/mmcblk0p6 of=/sdcard/mmcblk0p6.backup bs=4096": you broke your phone.
Those instructions must have either been completely wrong or instructions for another phone.
Basically you installed the recovery right between boot and firmware thus bricking your phone. You can buy tools to fix it bit that costs big $$$
Sorry for the bad news. I've been trying to find out if this phone has UART capabilities. I'll post it here if I find anything useful

thanks, the news is no surprise as i have been reading other posts that say the same thing. its too bad i paid $700 for this brand new over a year ago...thats a pricey brick. hopefully someone will be able to fix it as i am not willing to spend too much more on tools to fix it i will just sell it for parts or something. thanks for taking the time to look into this for me and let this be a lesson to all you other noobs who want to make the nitro better.

Never seen a phone technically hard bricked so I ask how installing the recovery between the boot and firmware would prevent from accessing Download mode? Logic would tell me, which can be wrong , that Download Mode comes before either of those thus no matter where he flashed recovery, download mode is still accessible. Please explain. Thanks in advance.
EDIT: From what I just read, dd if=/dev/block/mmcblk0p6 of=/sdcard/mmcblk0p6.backup bs=4096 makes a backup for the NitroHD before flashing the recovery. Found here. And, according to the article, the other command he ran was the recovery flash w/ the second command he used as a repeat, or excess.
after reading the above i noticed this is where i might have gone wrong.
[ NOTE: If you inadvertently copied "recovery.img" to the external or removable SD card, replace "/sdcard/" in the command above with "/sdcard/_ExternalSD/"
i didnt see this command in the first place but i did copy the recovery.img right to the removable sd card. im guessing the mistake i made is irreversible.

Apprently this person had the same problem as you. Many told that person it was hard bricked which is just strange to me b/c I've never seen a totally bricked phone, but apparently this is my first.
im being told its hard bricked but fingers crossed that im wrong. ive bricked many phones but always been able to fix them, this is my first possible HARD BRICKED device. when someone says they havent seen an actual hard bricked phone that kind of gives me a little hope.

That's the same boat I'm in. I've had 4 phones and fudged all of them to the point I thought I was bricked but could ALWAYS get download mode and flash stock firmware. I'm thinking you wrote over download mode thus not being able to access it and killing the phone. That's the only explanation I can come up with. Patiently waiting for maverick.marq to explain b/c I'm cursed w/ the having to know the how-to-the-why.
Just to be clear, you're trying to get to download mode by holding the vol UP button and plugging in to PC w/ phone off, right?
I'm assuming that all of the first sector p1 to p8 must be intact for download to work and since he wrote his recovery to p6 I assume it took out both firmware and recovery as (again a lot of assuming) the processor says OK look for firmware in block p1 doesn't find a complete image and it and then fails to boot.

i have held vol up, vol down, power, home, etc ive tried all the buttons. its my only phone so i will not give up easily i will continue to try all options until i either fix or replace it. this would have not happened if i could have only gotten the cwm recovery to flash properly the first time. i dont know why rom manager kept force closing and giving me the messaging error. i tried rom toolbox and it too gave me the same error. i soft bricked it and ended up getting stuck on the logo with security error but that was an easy fix. this is the only phone ive had a problem flashing, but this is a good learning experience. if i get it back up and running im not even going to try to mess with it after that.

thanks this was something i was curious about, i am going to contact them monday about it
mmcblk0p6 is the secondary bootloader. The idea is if you mess up your primary bootloader, you'll still be able to access download mode since it uses its own separate bootloader. By overwriting the secondary bootloader, you're making it impossible to use download mode.

Did u try flashing the stock kdz back on to it? Can u access download mode? Not recovery I am talking about the download mode. And yeah this phone is a pos when it comes to battery I am using a fat 3800 may battery and when I get lucky it maybe last 14 hours. This phone has so bad battery consumption.

i actually never read this guide lol i think youd be better off doing lgnpst. you dont have twrp because you have cwm. do the same thing, different programs. if you want i can pm you the files to lgnpst back to stock and then from there just reroot and unlock again.

For future reference to all, when you've stuck booting into recovery you just need to wipe the first part of your misc. I have a zip in the irc topic for it, ill link when I get home. Or you can just run the following in an adb shell
Code:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc count=1044 bs=1

Try this:
All you have to do is revert to an older version of clockworkmod, I used version 6.0.12 I believe.
the file name is: CWM6012-CM9-recovery so it might be that. Yep that's it, now i can finally rest

[Q] Stuck in sideload - Hold power button - Nothing happens

Hi, I was flashing a new rom but I accidentally select the sideload option and now I'm stuck there,
I tried to hold power button 30 seconds, even more,(also volume down + power button) but nothing happens.
Any idea?
It says:
"ClockworkMod Recovery v6.0.2.3
Sideload started...
Now send the package you want to apply
to the device with "adb sideload <filename>"
Please help I'm n00b -.-
I did that once and I didnt know how to get out of it either. Just pull the battery and restart.

No problem. Dont try that when something is running though. That might mess things up. But the sideload thing isnt running anything. Its just waiting for a command. They need to put a back or a cancel button on that.

Thanks for the advice but now I'm installing the crossbones ROM 2.3.0 but I'm stuck installing it,
I used to flash roms in my other phone a galaxy s3 and I've never had this kind of problems...
It says this:
Formatting system
Installing Crossbones ROM
that's all
What would you recommend me in this case?
Should I remove the baterry again? I've been waiting for almost 15 minutes and nothing again :/

You did everything right then. I dont know why it would hang. Id say pull the battery but like I said, it could mess something up if its actually doing something. Especially if it says it already wiped the system. If that happens, you're going to have to restore a factory image and start all over again. Its up to you if you want to take the chance. A ROM flash shouldnt take that long.

No problem. I hope you get it working. Or at least to boot up again.
Supposedly sideload in cwm is a bug with no way to back out unless you pull the battery or have usb connected [exit in command prompt?]. I was starting to like the touch recovery option, but recently i've accidentally pressed a couple of things i shouldnt have.
Sorry to hijack, but I'm attempting to sideload the 4.2.2 update from stock, and my sideload command seems to do nothing. I'm sure i'm connected as it displays my device number and "sideload" next to it. Using the sideload command simply displays the "help" list of the adb commands.
Is it a driver issue perhaps? Something else? (i noticed my batter was low just before attempting this).
Now i'm stuck in the waiting for adb sideload file.
hippochris: update your adb, or look in the help output to see if the sideload command is there. Also, i did this via stock recovery, selecting it in there.

I do NOT see the sideload option in the help output. I have all the latest updates from the SDK manager. Maybe i need to reinstall the SDK. I will give that a go. Thanks.

I've messed my phone with SideLoad, please help
I booted my Galaxy Nexus into custom recovery (CWM) for some other task but mistakenly gone into sideload menu!
Got no option to get back to main menu or reboot, i took the battery out and re-inserted. Now, my cell is not turning on since then!
Tried another time, took battery off but no luck..... what to do?
I've custom ROM, MIUI V5 4.2.2. My cell is unlocked and rooted, of course.
Please help.
What if the battery is non-removable?
Had stuck in that *** sideload on my SM-E500H and been waiting for the battery to drained it up all.
Yep, tried hardware button combinations as many times as I could.
if you can't take out the battery of your device and if longpressing whatever does not solve it
1. install adb on pc.
2. connect device with usb cable to pc
3. enter following command
Code:
adb sideload /dev/null
the device will complain that file is not valid but it will come out of the sideloading state

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?

please if anyone has the know how I would like to fix this phone rather then bin it thank you all happy 4th everyone
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

You ever get her fixed?

[Q] :( HEEEEEELP! STUCK AT LG LOGO WHEN I TRY TO BOOT! But wait, there's more......

I have spent the last 3 days searching XDA & trying every possible fix, no luck!
Here's my dilemma.....
I have custom recovery, TWRP 2.6.3.3, don't know what I did after trying to flash something........ I wiped everything except SDcard by accident. Like a darn fool, forgot after backing up everything via computer, to put a spares on my SDcard. Sooooo, I tried restoring by using LG FlashTool..... Here's where my problems began:
1. I can't load into download mode, it sticks at the logo to enter download mode but doesn't connect.
2. I tried ADB Sideload, sticks at "STARTING ADB SIDELOAD FEATURE.........."
3. No matter what mode (including Fastboot) I try, just won't connect to my computer the way I need it to. (*ALL DRIVERS HAVE BEEN REINSTALLED NUMEROUS TIMES, STILL NO LUCK.*) When I look in DEVICE MANAGER, it shows in "OTHER DEVICES" as "LG-LS980" (*Which is a good thing right? *)
At this point i'm at my wits end...... I tried to HARD FACTORY RESET, but didn't go thru. I'm afraid that if I tried it again, I could cause even more damage.
I've been without my phone for days & I'm about to go crazy if I have to pay LG or Sprint again for another phone!!!! I'd rather use my $600 on something else.
PLEASE TELL ME SOMEONE HAS FOUND A WAY TO GET AROUND THIS!
I've searched just about every forum & tried different methods.
Forgot to add that every time I power off from recovery, I get a the message about my device not being rooted, would I like to install..... When I swipe to install, nothing happens. Just powers off.

So try this...
Push the power button to turn the device on. Let it sit.
After you know that the g2 is on and trying to do its think, Press and hold power buttton, do not let go. It will force turn off the phone, but it will start to turn back on, if you keep holding the power button till it shuts off for the second time, you'll be set and the device will be fully off.
Have Lg Flash Tool open, make sure you have manual mode on and you point to the right dll and right tot file, could be zv7 zv8 or zva.
Click the arrow to have the flash tool biin check the files. when that is ready, do this next part fast. Plug in your phone, and immeditaly press and hold Volume up and Power. Download mode should appear.
and you should be good from there! If you try to enter download mode by using volume and up without the cable plug in, you'll hit the factory reset menu which is tied to the recovery, it'll do nothing, only take you to recovery. I hope this is of some help!
Edit:try new boot loader or system flasher via twrp
proplem i faced is one button which used to enter recovery is damged
Flash stock Ignoring the unmonted ianot able to be mounted then change system partitions u will be able to mount
Enjoy

I'm now completely lost.....
Ok... So i made a little progress....
I am now able to boot into fastboot mode.... No recovery now tho. If someone can help me with manually pushing everything I need to restore my phone, it would make my day!
I'm having withdrawal symptoms now. LOL! I MISS MY PHONE!
Problem solved!
Flashed all the partitions 1by1 via fastboot, was able to then reboot into download mode. Now using LG FlashTool to return to stock! I am now a very happy camper after a week w/o my phone!

Glad to see you've fixed your problem! I myself haven't been around, had some down time to. My sim reader magically stopped working and then randomly started working days later. Anyway, congrats!!!

Glad you figured it out. I was about to basically explain the steps to do exactly what you did.
Welcome back to the land of the living!

After she got it the first time, which we both congratulated her for, something went completely wrong. She dug herself even deeper, but broke download mode. That was extremely fun to fix.
