I think I've bricked my phone... After following the last steps in ADB, I booted back up and I keep getting this message with the LG logo in the back

---------------

Secure booting Error!

Cause : boot certification verify

-------------------------

------------------------------

Enter the fastboot...

Enter the fastboot...

Long time no see!

-------------------------------------------------

What do I do? I'm a major noob at ADB and stuff. Someone please help.

Edit : I can still enter download mode, but factory reset does not work. After pressing power button twice when it asks me to, it takes me back to the same following message as above.

I was originally on the ICS leak, trying to switch back to CM9
[LG Nitro HD] drumist:
Did you do the full guide or just the last section?

You can always install the LG ICS again and start over, or try the full unbrick guide.
[LG Nitro HD] JINXR:
let us know how it goes. mine did the exact same thing. trying the full guide didn't work, only applying the leaked update got it working again. I'm too scared to try again.
[LG Nitro HD] BeatByte:
Thanks guys, this fixed it back up again. I'll definitely try again in a bit and let you guys know if I succeed or anything.

--------

Edit

--------

Nope, same exact thing happened. Restoring back to ICS leak. Hopefully someone can tell me what I'm doing wrong. I install ICS leak, then root, then follow the last set of instructions precisely.
[LG Nitro HD] JINXR:
I'm starting to think it won't work if we try to mount those images while using the ICS leak. We have to get the Korean KDZ to patch.
[LG Nitro HD] scott0:
definitely do the full unbrick, the very 1st post of this thread.

that worked for me.

also-

full battery!!!!!!!!!!!!!!!!!!!!!!!!!

back that **** up!!!

i would wipe data at least 2x before starting the unbrick.!!!!!!!

if you tried the FULL method before and it did not work, I would also recommend uninstalling everything from your computer and re-installing it just to be super uber safe. even go back to a restore point previous to installing the LG drivers, small server, etc.

make sure you have usb enabled!!!!!!!!!!!!

good night and good luck. :)
[LG Nitro HD] hem.acharya:
what if your phone doesn't boot at and you cant go to Download mode .. how do we unbrick that?
[LG Nitro HD] Machzelet:
Exactly! The method we getting root on ICS leak is not a full root. This explains why CWM is not working on ICS leak and why we can't push stock AT&T images while using it and why we get security error every time we want to change something into system folder and then reboot the phone.
[LG Nitro HD] scott0:
how would i know?

i communicated what has worked for me re: returning from the leaked ics to cm9, which is the point of the couple of posts previous to mine.
[LG Nitro HD] hem.acharya:
Exactly thats what happened with me. i got security error after putting leaked ICS. to get the CWM working i tried to follow this guide i was successful till the korean ROM but when i tried putting att images it gave me "low memory error" while copying system.img. now the phone doens't start at all.

hard bricked i suppose :( . if i cant get the phone to boot and see download mode what can i do to revive the phone. any help would be appreciated ..
[LG Nitro HD] BeatByte:
So is there a way to get a full root on the ICS leak?
[LG Nitro HD] rani9990:
Root ICS

Yes, there is, unzip this file https://www.box.com/s/6f3481c1f362169cf242 on your PC and run the .bat file. This will get you root (most likely , haven't tested it myself b/c my phone is still in the LG warehouse after I bricked it :( [completely unrelated to this]) but Machzelet says it works - i trust the guy.
[LG Nitro HD] BeatByte:
That's the one I used to root before, so that's definitely not the full root
[LG Nitro HD] apieceoftoast:
Hopefully someone will find this information helpful.

Finally got the guide in Post #1 to work, on the p350 v10j.

It worked in a Windows 7 64-bit vm.

UpTestEX_mod2_marwin.exe would not run, I needed to install the msxml parser, included in the KDZ_FW_UPD_EN folder.

I was then getting the "Problem with communication between cell phone and PC" error, which was fixed by renaming the .kdz file to V10F_00.kdz (I had downloaded from a mirror). I also picked Emergency in the drop down list in UpTestEX_mod2_marwin.exe, not sure if that mattered.

At this point, it was getting further, but still stopping at 4%, I just let things run, and eventually it worked! It rebooted to the Korean firmware.

I then used task manager to kill the LG tool, since it was stuck at 4%.

From there i just followed the rest of the guide, starting at Getting root.

Big thanks to Flyview, red_solo_cup, fuzzyreets and Machzelet!

Your info in these threads is what got this working for me!

It's my first post, sorry if im stupid ;)
[LG Nitro HD] malox23:
Thank you very much for the info! The only thing I didn't try was to rename the damn kdz file and now it works! I actually took the kdz file from the ICS leak (V18), renamed it V18F_00.kdz and the flash worked. Didn't have to push over AT&T files afterwards this way. I didn't permabrick it! :)
[LG Nitro HD] JINXR:
Awesome!

I'm still leery to try the method again renaming the Korean KDZ file and keeping the Korean region and language. There has been a few guys that ran out of memory while mounting the system image, and I haven't heard if they've been able to unbrick after that.
[LG Nitro HD] malox23:
I just went back to CM9 from leaked ICS, no major issues with the method. I hard reset it twice while on ICS before flashing with the korean kdz. Rename the kdz file, choose english language, and flashed. Superoneclick won't root for me (tried >20 times), but when I used doomlord's batch file it went thru smoothly. Put the stock att files on, hard reset, and installed CWM & CM9.
[LG Nitro HD] BeatByte:
Wait, what exactly do I rename the kdz file to?
[LG Nitro HD] malox23:
V10F_00.kdz
[LG Nitro HD] BeatByte:
Because of you, I was FINALLY able to follow all the steps properly, go back to stock rom, install CWM, and recover back to my CM9 back up. Bless you sir!
[LG Nitro HD] malox23:
That's great news! I can't take the credit as I got the idea from apieceoftoast. This what the community is all about.

works
[LG Nitro HD] scott0:
just unbricked, start to finish = 29 minutes!

i use superclick 2.3.1 btw, 1st time rootie tootie!
[LG Nitro HD] ratatouille:
Maybe you got the idea from apieceoftoast, but you explained it so darn well that even I could get that piece of paperweight come back to life! Thank you again.
[LG Nitro HD] JINXR:
Me too! Now I'm running the stock V10f and my phone doesn't get hot and my. battery life is exponentially better!!

Even V10i and V10j got really hot and had horrible battery life.

Maybe I should go back to V10j and get it swapped out before my 30 days is up...

---------- Post added at 07:47 AM ---------- Previous post was at 07:19 AM ----------

Well I just tried to do the small 24mb update (I'm still on v10f), but it just errored out and the install failed. I tried changing the date to tomorrow and tried updating again. Same problem. It starts to update the firmware after a fresh reboot, but immediately errors out.

How can I get a completely stock v10i or v10j on here?
[LG Nitro HD] Gogeta5026:
HELP!!!

I followed the the unbricking guide, PERFECTLY, however I always get stuck on a Optimus LTE logo when the phone boots after step 16. HELP ME, PRETTY PLEASE!!! :)
[LG Nitro HD] aaki_rocker:
ok i have installed ics leak on my nitro hd !

if i want to get cwm back and back on cm9 can i just follow steps uptil rooting the phone ?

can i do it without ""Restoring the original Nitro HD images"" ?

thanks.. :)
[LG Nitro HD] JINXR:
No, complete the entire process. And be sure to rename the KDZ file to V10f_00.kdz after you download it to your computer.
[LG Nitro HD] aaki_rocker:
ohh !!

ok thanks.. :)
[LG Nitro HD] JINXR:
Ok guys, I really need some help and I'm out of ideas.

I need to get this updated from V10f to V10i or V10j. I tried applying the 24mb OTA update, but it keeps failing after 2%. I get error # 0x13e and then it boots back up into V10f.

I tried using the LG Mobile Support Tool from the LG website, but it says my software is up to date.

I unrooted using SuperOneClick and tried getting the OTA update again. No dice.

I did a system restore and just tried the OTA update again. No dice.

I read on another thread for the Optimus that this error happens when people don't clear the cache. But since I can't get to recovery, I can't clear the cache right?

Does anyone have any ideas? I really need to take this phone into AT&T and trade it in for one that doesn't burn my hand after a little usage.
[LG Nitro HD] ratatouille:
After reviving the phone, I installed ICS leak, rooted, changed the ATT bootanimation.zip and the shutdownanimation.zip (in system/media) to google gears, and I erased all ATT bloatware..... Now my phone just looks WOW.
[LG Nitro HD] hereric:
The best thing about ICS is the fact that it actually supports the screen on the nitro. Why they released a phone with a HD display without full support for the resolution baffles me completely.
[LG Nitro HD] JINXR:
Ok, found the command to clear dalvik-cache through ADB. Figured I'd try it without having root access. Didn't work. So on a hunch, I hit SU and guess what, I still have root.

:confused:

SuperOneclick said it was successful??? I don't even have Superuser anymore.

So I cleared the cache and I'm trying to apply the update again. <fingers crossed>

---------- Post added at 10:24 AM ---------- Previous post was at 10:17 AM ----------

That didn't work either.

I'm going to try unrooting again using SOC and see what happens.

What a PITA.

---------- Post added at 10:42 AM ---------- Previous post was at 10:24 AM ----------

Ran SOC 2.3.2 again. Still showing root access in ADB Shell.

I downloaded SOC 2.3.3 and unrooted it. Still showed root. So I rooted it, then unrooted it. Still showing root in ADB Shell.

Next step is to try DoomLord's unroot I guess.

---------- Post added at 11:07 AM ---------- Previous post was at 10:42 AM ----------

I'm too chicken to try DoomLord's unroot toolkit. He says it could mess things up if you originally root with something else, which I used SOC.

SOC seems to do everything, it removes busybox, superuser, and it says shell is no longer rooted. But SU still has root at the very end of the process.

:confused:
[LG Nitro HD] Gogeta5026:
HELP!!!

I followed ALL the steps perfectly, get to 100% and step 16 with the process of resuscitation and keep getting stuck at an LG Optimus logo. Does anybody know why this is happening?
[LG Nitro HD] kylereid:
I'm in the same boat! I'm reading all over... downloading another v10f (and renaming!). hoping this the issue. any help would be awesome! ;-)
[LG Nitro HD] kylereid:
dude, so i got mine to work. get a proper kdz file, and make sure of these:

in UpTestEX_mod2_marwin

a. System Type: CDMA

b. PhoneMode: DIAG

c. Select kdz file:... (self explanatory)

it was weird when it 'finished'. then turned off the phone, hard reset it (vol down, power... then power, power). and it worked!

good luck!

Secure/Fast Boot Error

Same Problem with a few other guys. Was on ICS leak but now im stuck with "secure booting error". I've tried the Unbrick method but got a small http error because of a missing file from the "www folder". Then I tried LG Flash Tool and just got a yellow ready sign for an hour. adb isn't working because my pc is confused with my phones drivers. Last I went into fastboot commands and flashed stock system.img, recovery.img, and boot.img from another thread yet im still stuck on this LG Secure Boot Error/Fast Boot Screen

SOMEONE PLEASE HELP!
[LG Nitro HD] JINXR:
Get ADB fixed on your computer first by uninstalling ALL phone drivers, reboot, then install all 3 drivers in the P930 zip file.

Uninstall the shttp program and then manually delete c:\shttp . Reboot and turn off all virus protection. Install it again making sure you have all the options ticked as stated in the instructions, including start up option.

Unzip the www.zip folder again and put them under c:\shttp\www, being careful to get the correct folder structure. ie: MAKE SURE YOU DON'T HAVE C:\SHTTP\WWW\WWW\...

Use Method 1 and RENAME the KDZ file to V10F_00.kdz.

Follow all of the instructions exactly. I was in your boat last week, but doing all of this got it working, even on a W7 64bit computer.

Lastly, GOOD LUCK

Removing ATT scrap

Could you tell us step by step how-to change the boot animation and find anything else than ATT to put there, same thing for the shutdown animation.

To remove all att bloatware, some apps can be uninstall and I have done this but there is more att apps and how I can remove all the scrapp from ATT?

Thank's

Alain

LG-P930 BELL with ICS Leak
[LG Nitro HD] rani9990:
MAKE A NANDROID backup before trying this.

First download any boot animation/shut down animation you want, the go to /system/media (ROOT ACCESS REQUIRED, and make sure it is R/W). There you will find bootanimation.zip and shutdownanimation.zip. Replace those with your dloaded zips. Voila.

To remove all the crap from ATT, get Titanium Backup and make a backup of whatever you want to uninstall, uninstall all the bloatware, check if there are ill effects. If there are none, delete all your backups you made. If there are, carefully restore one by one till the problem is solved. I didn't do this, I just froze all the bloatware, but it should work.
[LG Nitro HD] jrobinsky:
I am trying to do this but....The file won't download from his post, and the file later on in the link doesnt have the file to override to .exe...what to do I do? IM hitting nothing but dead ends trying to unbrick this phone and root it omggg
[LG Nitro HD] jrobinsky:
I keep having this issue when trying to unbrick my phone

UpTestEX_mod2_marwin it crashes and forces a close...anyone else having this issue?

windows 7 ultimate 32 bit

have tried it with backwards compatibilaty with vista, 2000, xp, etc no luck with any.
[LG Nitro HD] aaki_rocker:
try running it as admin !

also it may be a corrupted download so redownload and try again as admin !
[LG Nitro HD] jrobinsky:
It actually started working, then the program crashed again. I ran as admin. I'll download it again

---------- Post added at 04:50 PM ---------- Previous post was at 04:05 PM ----------

when i try to do 11) Click on "CSE web upgrade test".

It opens up a dialog that says "checking for new LGMobile update program. It shows that im up to date with drivers but says I can get some new driver im not sure which. Under ATT it doesnt even list the p930. So i go back to the main screen of UpTestEX and hit START UPGRADE. If I have the phone in download mode the program will stop responding and crash within 30 secs. If I have the phone on, it will last a bit longer, some words and stuff will show up on the screen, but it will still stop responding and crash. I have ran the program under admin, tried redownloading. Anyone have any other ideas? IS there ANY other way I can unbrick this phone. I want to root my phone so badly. I tried the other method that was posted but the file that needs to overwrite the .exe in the LG Flash program is no longer valid on the site, and the 2nd link that is posted does not contain the necessary file. PLEASE SOMEONE HELP ME!!!!!
[LG Nitro HD] jrobinsky:
I finally got it to unbrick (I now have Korean software with no data :( . ) I will explain how I got it to work after I finish. So I rooted, but now its saying I am not rooted. I suppose I will root again? And AM I suppose to root or shell root?
[LG Nitro HD] jrobinsky:
okay FINALLY its completed!! So on 3) Install shttp3.exe on drive C:/, note "I agree with this license, and I accept all items", "Update entry in main menu" and "Add to startup". Is where my issues started. When it says to install to C:\ i thought it meant to install to C:\. It means install to C:\shttps. I think that should be more clear. Once I got that to work the next problem was the length of the file name LG-SU640-V10F_00.kdz is too long and causes failures non stop. I shortened to name to V10F_00.kdz and it worked on the first try. As far as rooting. I found it MUCH MUCH easier and permanment to use DoomLord's rooter http://xdaforums.com/showthread.php?t=1321582

Now time to find myself a new rom ;)
[LG Nitro HD] DroiDIY:
Everything but the images worked

I FINALLY got the KDZ to load, got root, and proceeded to load the img's. The seemingly all went through (I got the # sign after each command, with the last one taking longest). I shut it off, and did the factory reset. But it still boots up into the Korean ROM.

Um, where did I go wrong??

AND, now it's bootlooping. Starts up, loads the home screen, then restarts.

EDIT: Aha!! I made a mistake in the Command Prompt commands. She is ticking along nicely, now.
[LG Nitro HD] davefootball123:
What program did you use to flash the KDZ file?
[LG Nitro HD] davefootball123:
I cant believe it, I was able to go through the whole process and get CM9 on my phone, running great now. :D

EDIT: Have the Hono kernel on at 1.7ghz with the samsung touchwiz nature ux port for the captivate installed...Running smooth as silk. Did the full debrick process on page number 1(post 1). Instead of using the kdz file in the first post i used the V10f_00 one on page 3 i believe. Worked great not a problem at all. It was more of a problem getting everything installed and ready to go haha.

Hi, i have a telus p935 with v10a fw. I tried to root it several time with different method with no result. After some research, if im right, i need to follow unbrick method to get root.

Finally, i get it.

It seem thats my problem was not server but the name of KDZ file.

I just rename file "v10f_00.kdz" and it worked. I get same error and get stuck at 4% with error of connection between pc and phone, but my phone rebooted and new firmware boot like a charm im now on v10f Fw.

Hi guys,

I have one question. Can we flash AmonRa 3.01 recovery on our p930 instead of CWM?

i have read few post where members mentioning Nandroid backup and this is only possibe in AmonRa recovery not in CWM. In CWM backup is different.
[LG Nitro HD] aaki_rocker:
nandroid is possible in cwm also !!

cwm touch is by far the simplest and the best custom recovery i've used in multiple devices !!

and amonra recovery is not available for our device !
[LG Nitro HD] xyz#1:
Thanks for reply.

I am new with bell p930. I installed HO NO cwm flashable but it does not boot. it keeps going to cwm recovery. I can install cm9. I can restore my stock gb 2.3.5 from backup of cwm.

My questions,

Is it necessary to install Korean version as kdz on bell p930 then root it and then install this leak ics4 (HO NO)?

What is the difference between cm9 and leak ics4?

Will I be able to install Official stock ics4 whenever it will be released?
[LG Nitro HD] NitroCM9:
Just wanted to say big thanks to Machzelet for the excellent instructions on rebuilding my Nitro's firmware. I (as well as many others from what I've read) have experienced a problem with severe lag starting to occur on their phone after switching SD cards for some reason. My phone was for all practical purposes totally useless, as the lag was so severe. It's now restored to full functionality running CM9 after using Machzelet's procedures. Thanks for all your help, Mach.
[LG Nitro HD] abhaymitra:
I installed the ICS leak from exe and rooted my LGP930. Using Nobloat, I disabled few apps, and it worked fine. Yesterday, I disabled Google Videos and after reboot I'm getting "Security Error".

I can go to download mode and factory reset it, but the security error wont go away. I tried to reinstall the ICS leak exe but it says " Connection problem between phone and PC". The phone is however recognized by LG Mobile Support Tool.

Will unbricking my phone using this method work for me ? I've read about some people complaining about "Less memory" error. The reason I want to be sure is because I dont live in the US and will have no option if I permabrick my phone. :(
[LG Nitro HD] aaki_rocker:
i think you will have to unbrick as you have no option left !

could you anyhow grab a screenshot of the error message you're getting ?
[LG Nitro HD] infamouscheater:

[LG Nitro HD] Flashadmin:
I have LG Nitro HD (P930, AT&T).

I tried back from P930_UDT_v18f_04112012 to korean rom by unbrick guide but got strange - the phone starting boot with "LG Optimus LTE" logo and stripe running few seconds and stopping... I tried flash again and againe korean firmware and same result... After I tried flash P930_UDT_v18f_04112012 again (just start update when phone been in download mode) and the phone booted up in android 4.0.3 (ICS leak).

I got the phone work by flashing V10C (2.3.6 for P936) with unbrick guide! This's strange - the phone can't start after flashing V10F, but start after flashing V10C!

Also, I tried write images (boot, recovery, radio, firmware, system from 2.3.5) with dd under V18F (ICS leak) and got "boot certificate error"...

What the problem with my phone and V10F firmware? Does LG flashing software check controll summ of the file? How can I get CWM in this situation to get CM9?

Thanks for reply.
