First of all you need to have fastboot enabled on your phone. This is a special boot mode that is disabled by LG. To get it you have to flash your phone with a fastboot-enabled rom. After that, camera+power will put your phone into fastboot and you will be able to flash recovery.
If you're somewhere in Europe, here's the current Europe Open ROM with fastboot:

Okay thanks
And now the next stupid question :-/
On my HERO I flashed new ROMs using recovery
How do I flash a ROM on my LG ?

you can flash custom roms via fastboot or if the developer has made a recovery backup you can flash with that

After alot of googling, I found KDZ_FW_UPD
it got it to work

[Q] Did I brick my Nexus 4?

Hi,
Last night i was playing with my N4 (with some root applications) and an app asked for a reboot. I just pressed yes so that the phone will reboot (I have done this earlier without any issues). Suddenly the device doesn't boot up. My N4 is stuck at a black screen. While trying to boot up, the Google logo appears and then a black screen. It doesn't advance to the 'X' logo. I'm running on stock, rooted phone (used N4 toolkit by Wugfresh to root).
I'm able to boot into recovery although. I tried all the possible means, wiped cache, dalvik cache, did a factory reset, backed up the system and tried to restore the same. Nothing happened.
Then i tried the "Back to Stock" option in the N4 toolkit and chose the option "Soft-brick/Bootloop" to recover my N4. These are what happened:
Downloaded the 4.2.2 image from Google servers and tried to flash in the device with prior instruction from the toolkit. Everything went fine until the flashing process. In the last step the CMD window opens up saying it is unrooting and flashing stock and immediately it'll bring up a complete message saying the flashing is complete and to wait until the device boots up. But nothing happens again.
I tried the automatic flashing and on the downloading window it saying download failed and hash checks failed meaning its not downloading.
I searched all the possible threads in a day to find a similar problem but in vain. I'm not a noob but i'm too lazy . But i would do anything to bring my N4 back to life. Anyone please show me a direction.
In short:
Status: Soft-Bricked (guess so), black screen after Google logo
Version: Stock 4.2.2 (rooted+busybox+supersu+twrp)
Able to boot to recovering: Yes, bootable to recovery and bootloader.
Tried Nexus toolkit recovery: Yes but in vain.
Gave up: No and never, I'm searching and searching for answers and I'm worried if I'll end up in a hard brick. :crying:
Guys, please help.
Thank You!

I'm just taking a wild guess here - I'm not responsible if anything bad happens, and you might want to wait to someone else seconds my suggestion in any case (although I can't imagine things getting worse as long as you flash N4 stuff). But have you tried flashing a new boot.img/reset kernel from recovery or via fastboot/toolkit?

Err...nope I haven't tried any and will wait until someone seconds you. Meanwhile I have wiped off the ROM through the option in recovery. Still will I be able to do what you said? Also if could direct me to a "how-to" thread would be great. Just that I don't wanna mess up again.

Also, is there a way to transfer a ROM to N4 through fastboot? So that I can install the ROM through TWRP.

No, my suggestion would require that the ROM is still on the phone, so you should restore your ROM prior to my suggestion. And I'm by no means an expert (therefore the disclaimer), but I *think* that since it's a bootup problem, it could be solved by flashing a new boot.img (which is essentially flashing a new kernel to the system).
But yeah, let's see if others think this might help, haven't researched it, is at work right now. Just throwing in a suggestion, that's all...

I *think* (again, I'm totally not sure about this, as I haven't tried it) that you can sideload a ROM via zip file from recovery, but since I haven't tried it I'm not sure - can anybody confirm???
EDIT: Chromium's suggestion is better, by pushing the ROM.zip to the device and flashing from recovery (check md5 first, just in case).

Yes there is. Your nexus is not bricked and this is why you shouldnt use toolkits to do things. This is honestly an extremely easy and simple fix. Use adb to push a rom onto the n4.
Code:
adb push \path\to\rom.zip /sdcard
Boot into recovery, do a full wipe, and flash the rom.

You said you downloaded the Google images.
Just boot your phone into the bootloader and run the flashall.bat that is in the Google image folder.
Note this will probably fully wipe you're phone in the process

Okay, thanks guys. I'm on it. Will let you know when I'm done.

That same thing happened to me once. I had to extract the google file and look for the 4 img files(bootloader, system, userdata, recovery) and flash them with toolkit manually and it fixed it, but it erased everything on my sd

I tried to load the file "occam-jdq39-factory-345dc199.tar" into my phone using the ADB sideload feature in the toolkit. I don't have the SDK installed hence I depended the tool again. But now the tool only loads .zip file and not .tar as the one that i downloaded. Am I doing it right?

K if you have a custom recovery installed, there isnt much you need to do to fix the issue.
First setup adb/fastboot by reading this
Then boot the phone into recovery, and plug it into the computer. Open a new command prompt window and use adb like this:
Code:
adb push \path\to\rom.zip /sdcard
Then you can unplug the phone. From recovery go to the install menu, find the rom that you just pushed, and flash it.

Okay, installing the SDK. And the command saying "rom.zip", the file that I have is like "rom.tar". Does it matter? I downloaded the rom from here https://developers.google.com/android/nexus/images

No the tar wont work through recovery. You should download a rom from here or here.
If you want to flash the stock rom through recovery you can download it here.

[Q] Unable to Flash Nexus 7

hello everyone..
In serious need of help here and hope someone can help..
Due to the massive battery drain issue I have been having, I tried to flash the original stock rom on my nexus 7 and
things have gone downhill really bad..
in the past, I flashed using this guide (http://forum.xda-developers.com/showthread.php?t=1907796)
without any problems but last night.. I encountered errors when trying to flash the bootloader
and radio IMG files.. neeedless to say when it comes to flashing the rom in, it came out with errors and my nexus remain OS-less
the errors when trying to flash the bootloader and radio are
"failed (command write failed (Invalid Argument))"
can anyone help me?
p.s :- if anyone can even suggest me a easier way to flash custom roms in and so forth, your suggestion will be most welcomed..
also, I did try wug's rootkit plus the nexus 7 toolkit or something, both came out errors too when too do any flashing in relating to
the bootloader or system.. thanks

Why were you trying to flash the bootloader? Were you trying to update to 4.18?

actually, my bootloader boots fine, it shows tilapia 4.18.
so does this mean I dont have to flash it?
if I dont have to flash the bootloader, do I have to flash the radio?
sorry, kind of a noob in these things..

Anyway, is it normal for the bootloader flash attempt to fail?

No, it's not normal for it to fail.
You really don't need to flash either unless one of them is screwed up or you are upgrading to a newer version. Bootloader flashes are risky anyway. To avoid flashing them, you can either remove code from the updater script or remove them from the factory image files entirely.

Try to unlock your bootloader before flashing image with the command:
fastboot oem unlock

Then it sounds like something happened to your system partition that should not have happened.
Are you sure the system image you're trying to flash is valid, do the md5 sums match?
How about flashing another system image?
Or flash a custom recovery, and install a new ROM from there?

As a rule, don't do anything with a toolkit that you don't know how to do yourself with the relevant fastboot or ADB commands. It has a nasty tendency of leaving you in a lurch.
I noticed that your last run of Wug's toolkit did claim to successfully flash your recovery. Have you been able to access it from the fastboot menu on the device? If so, that's a major step forward.
Perhaps most importantly (based on your mentioning of tilapia earlier), are you 100% certain that you are trying to flash the factory image for your model of the Nexus 7?

Yes, I am absolutely sure it is the image for my nexus 7.. which is 3g/wifi model, not just wifi only..
image file is downloaded using wug's rootkit too..
file name = nakasig-jdq39-factory-0798439d.tgz
as the snapshot shows.. it keeps showing failed when "sending system"
please tell me you have an idea on why it keeps failing there...
*crosses fingers*
p.s :- after that (numerous) wug's toolkit attempt to flash back stock rom, I tried booting to recovery and it shows the android on its back with a red exclamation mark on its open body chasis

I'm assuming you haven't tried this yet, if you have tried this just ignore.
1 - Download - http://techerrata.com/file/twrp2/grouper/openrecovery-twrp-2.6.0.0-grouper.img
2 - fastboot flash recovery openrecovery-twrp-2.6.0.0-grouper.img
If flashes fine:
Power off Nexus, Hold Volume down and Power on, keep holding power down until you get to recovery.
Then:
Either - Get a USB OTG and put a ROM on a USB Stick, go to "install" - "Use external storage" find the rom and flash it.
or
Plug in to PC whilst in recovery, - Mount Storage - Now the Nexus should pop up on PC, Drag ROM to Nexus. Unmount and then try to flash.
Let me know how you get on with this.
Regards.

That's because you have stock recovery installed now and it's unable to verify that your device is in working order, hence the red mark. Find TWRP for your device, download the .img and try to flash it with fastboot flash recovery <path-to-recovery.img>. Since you can at least get into a recovery, it's possible you'll be able to use onboard recovery tools to see what state your internal partitions are in.
Until there's a little more info available, there's nothing I can say that's not pure conjecture.

Stock Recovery will not Flash

Hey guys I could really use some help...I have twrp recovery but unfortuunately when i try to flash stock recoveryy back, it will not change. I have tried fastboot, nexus toolkit by wug, flashify, image flash gui, etc. Do you guys have any suggestions? Thanks so much!

I've found three recoveries floating around on the forum so far. Two are in this thread -- one is in the first (1st) post under the "recovery" subtitle and the second is in the seventh (7th) post.
The other one is in this post. You have to download the Nexus_7_Restore_F.zip file and unzip it. Once you do that you will find a recovery.img file in it.
Hope one of these works. My bet is the last one will at the very least. Let us know how it turns out for you.

Thank you so much I'll let you know! Ah it looks like the stock kernel is in the last one too that's good..hopefully sometime soon we can get factory images to make things easier haha

I tried flashing all of the above. With the third one (contained within the Nexus_7_Restore_F.zip), when I reboot to recovery, I get the Android with the red exclamation mark, no go. So I manually flashed TWRP back. It seems that until we get an official factory image from Google (if ever), we're stuck on TWRP. Unless there's something I haven't considered.

Unless I'm mistaken the Android with a red exclamation is what you should see if you have the stock recovery installed...which means it was successful. At that point there is some combination of buttons that must be pressed to restore the recovery but I don't remember what it is (I think it might be Vol up + Power but I don't know for certain so I wouldn't try that until someone else confirms it).

[Q] Problem with TWRP in rooted and unlocked nexus 10

Hello guys, first time posting here, I'm pretty sure it's a silly question, sorry if it is but I couldn't find the answer anywhere. I have an unlocked and rooted device, I installed the last 4.3 update this morning, and usually TWRP let me automatically fix the root just after install the update. But this time it just installed it and booted the tablet, and when I try to enter the recovery mode to fix the root in TWRP, I only see the droid with the exclamation mark.
So the problem is that I don't have root, and I cannot enter TWRP to fix it. TWRP went away with the latest update?. For entering the TWRP I pressed vol+ vol- and power and the pick recovery... is it correct?
Thank you in advance for the great community we have in android and sorry for my english

The same thing happened to me, I resolved it by:
- download a recovery image such as TWRP to a desktop/laptop and then flash it via abd
- now boot into recovery and flash SuperSU 1.51 or higher (1.55)
From what I read you probably did this once before. The 4.3 update overwrote your recovery image and root.

Nice that it is solved but please do nog use toolkits anymore. I respect the effort and time people take to make them but learning fastboot is just way better. Maybe harder but hard work pays off. Almost everyone will tell the same.
For people who want to use fastboot:
1. Flash custom recovery via fastboot.
2. Boot into recovery.
3. Flash latest supersu.
You can put solved in the title by edeting it.

Good time . I have a similar problem : after a recent update missing root. I tried to flash a custom recovery by fastboot, but the process hangs at downloading recovery.img to nexus. I tried using other drivers and a different version of fastboot, but to no avail.
Ps: by same drivers and fastboot I got the root before.
