I followed a stupid link that said "Install CWM for LG Nitro HD" but the recovery was for Thrill. Now I don't get Pwr+Vol+ or Pwr+Vol- or Pwr.

How do I unbrick this puppy?
[LG Nitro HD] aaki_rocker:
can you start the phone ?
[LG Nitro HD] sandhuxda:
Nope :crying:
[LG Nitro HD] sandhuxda:
I got the phone with stock latest GB. I installed leaked ICS, then rooted the phone successfully and was looking to install CWM. That's when I came across this link that purported to have instructions on how to install CWM on Nitro. Basically, download a recovery image and dd it to a dev block device. I did that and not sure why, hit factory reset. After that the phone's been cold dead. Turns out the link for the recovery.img was for the LG Thrill. Grrrr. Some stupid fan group out of Bhilwara, Rajasthan runs the site with the stupid instructions. I suspect it is just SEO site to make money off ads and pilfer other people's work.

Anyway, I left the phone on charging for several hours, have tried removing the battery several times. The LG recovery tool does not recognize the phone. Adb sees nothing. However, when I connect the phone to a new USB port on Windows, it finds a new device and tries to install driver for it but fails.

Weird because I have the latest LG drivers installed.

I suspect this phone is bricked for good. Maybe I can convince LG support to give me a replacement? :P
[LG Nitro HD] sandhuxda:
Did you find a fix? I am bricked hard as well. Blank screen no matter what combination of keys I press. When I plugin to Windows, I get QHUSB_DLOAD device that's trying to find a driver.

There is a silver lining though. Looks like guys unbricked HTC Sensation with the same symptom.

Korean SU640

I have a Korean (SK Telecom) SU640. Originally I had 2.3.5 which was rooted and running nicely.

I went to the LG site and updated to 4.0.4 and now my phone is running a lot slower and I cannot root it. The battery runs down a lot faster and it takes time for the phone to catch up with my screen touches.

Should I try to unbrick it as in the original post or is there an alternative specific to my South Korean version?

Thanks

I only have a Normal Web Upgrade Test button to press in the flashing program?? Where do you see CES Upgrade??
[LG Nitro HD] rani9990:
Right then, the only way I known of to fix this is to send it off to LG. The damn thing won't turn on right? LG will fix it. Happened to me too using android authority guide. I convinced them to take that down though.
[LG Nitro HD] KM626:
I'm having the exact same problem as this guy here. Can't seem to figure out what's up, since his solution didn't make any sense at all. I double checked everything and it's all done right.

How the heck do I fix this? I've been at it for 2 hours, and I'm getting nowhere.
[LG Nitro HD] tampaboy1984:
the lg flasher app keeps telling me my phone is the latest version and will not let me recover the phone?? How do i get past this?
[LG Nitro HD] JINXR:
Let me make sure I understand you correctly. You've unbricked and now you're trying to update your phone using the LG mobile support tool?

If so, you can't. I had the same problem and never figured out how to get it to update using OTA or the mobile support tool. Once you unbrick, you're stuck with V10f unless you put a custom recovery and ROM on it.
[LG Nitro HD] dillonr:
can you use this to put a different stock rom on your phone (still the p930 firmware though)?

if someone has a stock p930 how can they get the files required to do that, or do you have to get it from lg's servers?

thanks
[LG Nitro HD] drumist:
You can use it to install a different KDZ, but there haven't been any English KDZs leaked or released for P930 besides the ICS leak.
[LG Nitro HD] dillonr:
so there is no reason for me to get the .img files i see around the internet from my stock (V11a) phone (P930)?

if i was to get them (so i know they are for my phone, not the thrill or another device) how would i go about doing that?

i have been looking for this answer all day lol
[LG Nitro HD] drumist:
Well, the problem is you have to have root in order to create an img file from your ROM. So unless you or someone else discovers a way to root V11a, then you can't get an img for it.

The reason the unbricking guide instructs you to use the Korean KDZ is because that ROM is rootable, and once rooted you can install CWM and then a flashable custom ROM from there.

Stuck at 4%

My computer always gets stuck at 4% no matter what. Is there a solution?
[LG Nitro HD] JINXR:
Did you rename the file to V10f_00.kdz?
[LG Nitro HD] dillonr:
it is easily rooted with superoneclick...and it seemed to have fixed my battery life also...how would i go about making an img file?

thanks :D
[LG Nitro HD] drumist:
You can issue the following commands from adb shell or from terminal emulator from the phone itself.

su
dd if=/dev/block/mmcblk0p8 of=/sdcard/boot.img
dd if=/dev/block/mmcblk0p13 of=/sdcard/recovery.img
dd if=/dev/block/mmcblk0p1 of=/sdcard/firmware.img
dd if=/dev/block/mmcblk0p14 of=/sdcard/baseband.img
dd if=/dev/block/mmcblk0p27 of=/sdcard/system.img

This saves 5 img files to the sdcard root directory, which you can then copy off of the sdcard or do whatever you want with them. Make sure to first delete any previous img files or use different filenames for the img files so you aren't overwriting anything. The system and boot partitions are the most important ones, but it's not a bad idea to make backups of all of them!
[LG Nitro HD] dillonr:
thanks again, i used "adb shell" and then those commands (after looking them up and learning a bit also) to get the files. then i put the files on my computer and started to upload them to db.

if anyone wants these files they will be put in my dropbox...i will put the link to it in my signature tomorrow morning after it all finishes uploading :D
[LG Nitro HD] dudesthisisthebest:
Trying to root yet continually getting "no such file or directory". Tried 2.3.2, 2.3.1, and TPSparkys. Any suggestions would be helpful.

I debricked to v10f from the ICS Leak. Debricking went fine, rooting has not.

EDIT: Solved by redebricking
[LG Nitro HD] JINXR:
If you unbricked, you should have come out of it with a rooted V10f.
[LG Nitro HD] dillonr:
not sure if it will help, but try updating and re-rooting with superoneclick...

my phone was updated (to V11a) and i had no trouble rooting it....

i uploaded the .img files for my phone to dropbox (see my signature) and you might be able to use those if updating fails to see any newer versions.
[LG Nitro HD] JINXR:
Once you're unbricked and have V10f, the stock updater (both OTA and through USB) is broken.

He should have a rooted V10f already, otherwise he wouldn't have been able to get V10f on there.
[LG Nitro HD] dudesthisisthebest:
Well I just decided to do the unbrick process again. This time I got root using SOC 2.3.2 on my 8th try or so. Thank you for your suggestions though, V10f really sucked
[LG Nitro HD] KM626:
I was actually looking for those. I have a Bell p930 and wanted to go back to stock for two weeks, and for the life of me I couldn't find the files and thought I was screwed!

I ended up accidentally finding them on the google drive from HO!NO!, and have since downloaded and saved them to my computer. I can try and upload them in my dropbox for anyone else who needs them as well!

Funny. Mine was stuck at 4% for the longest time (I'd say about 7 minutes), and it rebooted into the korean v10f firmware. It was on standby for about 10 minutes and was still at 4% on the update tool, so I force closed the update tool and went on from there. Maybe give it some time.

When yours is stuck on 4%, did it come out of download mode and boot up afterwards into the original firmware? That happened to me at first, but I couldn't explain what happened. Most likely it was something in my set up in which I fixed.

What i did though was download the v10f_00.kdz file from the link posted by flyview (post #132, page 14 in this thread) and it worked. Also make sure you double check everything is set up correctly.
[LG Nitro HD] dillonr:
Km626, what version are the img files you have?

Mine are the V11a if I haven't said it enough :)

Just remember to ask HO!NO! Before creating a mirror of his files and make sure to give credit where it is due

Hi I believe that my phone is bricked as it has the severe lag that others have mentioned in other threads so i was wondering if this would work on the Bell Lg Optimus LTE

Im sorry if this has already been answered but i didnt see
[LG Nitro HD] dillonr:
bricked usually refers to not being able to use your phone at all (screen won't turn on...etc.)

you should be able to use this guide for your optimus LTE, as it is a P930 device.
[LG Nitro HD] chinese.chopsticks:
So do you think I should use this guide? Or do you recommend any other way?

Any help is greatly appreciated
[LG Nitro HD] ajt1995:
I wouldn't LOL

It ruined my perfectly good NITRO
[LG Nitro HD] JINXR:
Why did you pull the battery? It's easier to just turn the phone off.

Also, are you sure you're holding down the volume down before holding the power button in order to do a factory reset?

If that's not working and you can't even get to download mode, then I think your phone is done for.

But you can't blame it on the guide. You had to have done something wrong. Too many other guys have been successful. I too thought it screwed my phone up, but I finally figured out I missed something and made a mistake. However, I could still get to Download Mode and just started over.

Sorry for all the questions guys but i really dont want to mess this up

some how got in and now its checking connection with cell phone i hope it works

now after it analyzes pc enviroment it will analyze phone enviroment and end up telling me to disconnect pull battery turn on and press restart button anyone know what i can do?

imei is located underneath the battery
[LG Nitro HD] chinese.chopsticks:
okay so my main question now is can i just press upgrade in the marwin tool instead of using cse web upgrade as that doesnt seem to be working

Machzelet?

The driver when i plug in the phone out of 3 that is not working for some reason it just keeps saying installing is the LGE CMDA usb modem, would this be the problem regarding using the upgrade program and getting stuck at checking the model number?
[LG Nitro HD] chinese.chopsticks:
by unplugging and replugging the device i can get to here

But now its stuck here
[LG Nitro HD] chinese.chopsticks:
Do you guys know if there is any other drivers i could use i think this is my problem

and in this screen should it be like this? or does this mean that my phone is not connected?

[LG Nitro HD] JINXR:
It doesn't sound like you have your host file setup correctly. The LG Mobile Tool has to interact with the LG website, that's why you have the host file modified so that it can't "talk" to the LG website. The http software picks up the traffic that was meant for the LG website and tricks the LG Mobile Tool into allowing you to flash the Korean KDZ file onto your phone. But if the LG Mobile Tool can contact the LG website, then it will tell you that your phone is up to date.

So make sure you have the host file modified correctly in order to redirect the traffic to the http software.

Hey, I have a question: Which version of CM9 is everybody using? I tried the RC2 for the p930, but it wouldn't get past the CM9 splash screen (and it would freeze and restart several times, first.) I also tried the HO!NO! leak, but that didn't even get past the LG logo.

On a side note, I haven't been able to get wifi to work on the Korean or rooted "stock" firmware afterwards. I've had to do a similar process with CWM recovery, as I did with the stock images (command prompt, copy to phone, factory reset) to get it on my phone.
[LG Nitro HD] HO!NO!:
Before installing do you wipe all (factory reset) in cwm?
[LG Nitro HD] keboose:
Yep. Factory reset, cache wipe, (and I think I wiped the dalvik cache. I'm not sure why, I just saw that someone else did it.)

And just to be sure, there is no separate kernel pack I have to install, right? On my last phone I had to install the CM zip and a separate kernel pack.
[LG Nitro HD] drumist:
Make sure you are using CWM 5.8.2.0 (installed via ROM Manager, if you don't have that version). Older versions will not work correctly.

If that's fine, you might try formatting the system partition via CWM before installing the ROM to see if something just wasn't being cleared properly.
[LG Nitro HD] keboose:
Ah, well, see, like I said, I can't get wifi (and I'm not using data, I don't have enough $$ on my prepaid plan.) is there any other way to get CWM on the phone (without using adb?)
[LG Nitro HD] drumist:
Yes. Download here: http://download2.clockworkmod.com/recoveries/recovery-clockwork-5.8.2.0-p930.img and place it on your SD card.

You'll need terminal emulator installed to apply the update (or adb). If you don't have that installed, I guess you can look for an apk for it. If you have it, and are on a rooted ROM, you need to do this from terminal emulator:

su
dd if=/sdcard/recovery-clockwork-5.8.2.0-p930.img of=/dev/block/mmcblk0p13

Then you're good to go.
[LG Nitro HD] keboose:
THANK YOU!

I must have been using a different version than I should have been. The one I used has smaller text, and there was no touch support. HO!NO!'s mod is working great now!

Time to put in my sim card and restore my titanium backups! are there any known issues with the leak?

---------- Post added at 11:15 AM ---------- Previous post was at 11:08 AM ----------

And out of curiosity, which one do you think works better, now, the CM9 build, or the leak?

Edit: okay, I'm a bit peeved about this: the phone s only playing music in mono (the same track in both ears, centered.) Is there an option to fix this?

Edit 2: Okay, I tried installing CM9 through the ROM manager, and that didn't work (still,) but the phone is playing music in stereo now that I reinstalled the leaked ROM! Thanks for your help again!

How to fix OTA update?

I have seen it mentioned a few times throughout this thread, as well as others, that this unbricking method breaks the OTA update once you are back to v10f. I am needing to get my phone back to full stock, unrooted, and up to date. I have managed to get my phone back to the v10f from the ICS leak and I have managed to unroot my device. Now all I need to do is just get the phone up to date. Anytime I try to update, the phone will download the update and then restart to begin the installation. Once the phone reboots at 2% the phone will flash a message that says Err 0x13e and will restart.

As I mentioned, I have seen it mentioned that the unbrick breaks the OTA update as well as the USB update, but can anyone tell me how to fix this? Surely there is some way to get the phone back to a state where it can install these OTA updates.
[LG Nitro HD] drumist:
Actually there is no reliable way to do that. There is no KDZ available for restoring the phone to an unrooted ROM, except for the ICS leak which is not a completed and released version (or the Korean one that people use for unbricking).

If the AT&T and/or Bell final ICS update comes with a released KDZ, then you will able to restore the phone to 100% stock.
