Please help!! Bricked my Rogers P925g!

I need some help to unbrick my Rogers branded O3D P925g. I was able to root it and manually install the camera mod from erosized. Then i tried manually installing the performance pack and when i rebooted its looping at the Rogers screen. Can i use the unbrick method from the p920? Thanks again.

I had mine bricked as well and this method worked great for getting it back.
Step 1: Get the newest KDZ file for your phone/carrier. I got mine from here:
http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=xxxxxxx
Where xxxx is enter the IMEI of your phone which is found under the battery.
Step 2: follow the instructions here:
http://forum.xda-developers.com/showthread.php?t=1186406\
This will bring it back from pretty much any state. Mine was not even booting up to the LG Logo and this restored it.
Good Luck.

Just fixed mine. Use LG Update Tool, Click on Customer Support and then Recovery Phone. Enter your IMEI number and it will completely wipe the phone contents and install the newly released v20c BB and software. This process took me about 20 minutes and then an additional 10 min or so to boot into the OS. Worked flawlessly with my SIM and microSD still in the phone. Didn't loose any data from my microSD either. Got 4G back as well. Note that rooted state will be removed and CWM Recovery will be replaced with Android Recovery.

Same Problem no resolution
I have the same phone and when I use those links I cannot get anything to show up no matter how i enter the information.
My phone is stuck on the lg screen and it wont boot up. could someone give me a link to LG P925G stock firmware or some method of unbricking my phone. i have't had much luck.
all because I used Rom Manager too.
I cannot even go into recovery mode is my phone totaly bricked? I need some tips.

here is the most easy and straight-forward way I discovered to unbrick or overcome any flashing error no matter what it is (it applies to lg o3d, and thrill 4G, I think it will apply to their fellows)
1-you must have drivers installed of-course
2-remove your battery
2-open your pc device manager and look at COM and PORT section
3-hold volume up button (only) and connect your mobile to pc through USB while pressing this button, and keep pressing until you see a new port has been added and installed in your COM and PORT section (about 15-20 sec), now you can release the button, be sure that port will stay apparent after releasing the button, or repeat this step (with longer press on volume up button)
4-put your battery back and don't touch your phone again
5-now start flashing by following these 2 tutorials in order:

[Q] Need Major Help I Screwed Up

Hey ppl! I messed up my phone and I need some help. I have a G2x and I recently rooted it using the root.zip I found on one of the forum threads here. It worked fine and I flashed over to Eagleblood 2.5 and I didn't notice when I downloaded it that it didn't come with the google apps. I couldn't figure out how to get the google apps back into the phone since market wasn't installed. I tried downloading it but the phone kept telling me I don't have an SD Card being that I don't have an external one yet. Yes, I could have just downloaded it on pc and then transfered market apk via usb but I couldn't find the option to activate usb which was weird. Usually when you plug in your usb cable the driod icon pops up. So instead of flashing back using the backup I made on CWM I used nvflash and then used that LG tool to install V21E_00.kdz to install Gingerbread again. That's where everything messed up. I no longer was getting a cell signal and the battery icon had a ? in it. I assumed that the installation went bad to i did the process again with the nvflash and the V21E_00.kdz file. I got the same results again. I managed to get the wifi working again cause it wouldn't connect and downloaded cm7 7.1.0.1 to see if it would fix the problem. I flashed over and got the same results on cm7. No cell signal and battery icon screwed up. I gave up and did a full wipe and tried to install Gingerbread again. This time my pc wasn't reading my phone anymore when I connected it to the usb to use the LG tool to install V21E_00.kdz. Now my phone is in a cm7 boot cycle. If my phone is broken just tell me so I can dump it. My friend warned me about the G2x and I didnt listen cause I was in a hurry to get a nice phone. Any input and help would be greatly appreciated. If you guys need more info on anything please ask. If I can salvage this hunk o' junk I'm getting rid of it.

This phone is unbrickable damn near, have you tried the rom for recovery in development section? It will low level nvflash your phone to GB OTA 2.3.3 good luck.

Great! Thanks for the help. The phone is somewhat alive but I still have no cell signal and my battery icon has a question mark in it again. I was reading on that thread you linked me mentioning to do a firmware upgrade using the kdz file or LG Tool. Do I have to flash the firmware to get the cell signal working and the battery icon to work? If so, where do I get the firmware to flash?

To fix the boot loop cycle just boot back into clockworkmod recovery and do a factory reset, wipe cache, Dalvik cache, and then reboot and give it several minutes (first boot takes a little longer).
Or since you said you have a backup, just boot into clockworkmod, do a factory reset, format /system, and then restore your backup.
Again, the first boot always takes a little longer.

Thanks phburk I managed to get the phone working again with the flash.bat file from the link posted but I still dont have cell signal and battery icon has a question mark in it. I'm trying to download and use the LG Update Tool to see if that flashes the firmware to get the cell signal and battery icon working again.

The LG Update Tool fails at 30%. I can't get wifi on the phone to work and I have no cell signal and battery icon has a question mark still. This phone has to be broken. I see no fix in site for this problem. Anyone want to trade a GS2 for a G2x?

If you have a backup from a working configuration, try restoring that. Before you restore it, boot into clockworkmod and do a factory reset, and then format /system. THEN restore your backup.
After you restore allow the phone to reboot. If you still don't have signal then go to Settings > About Phone and see what it says for Baseband version.

Right now its going to show "unknown" for baseband. Might sound stupid but remove the battery sim card and sdcard for 5 minutes or so and then put them all back in and reboot. Try that after the factory wipes and installing a new rom. I've done that when I saw the "?" And no cell or data...

I'll give it a shot. That's all I can do at the moment.
I no longer have a backup. The backup got corrupted that's why I've been trying other methods of restoring my phone. After running backup from CWM, the phone would reboot and stay on a black screen and flash. Screen would go dim then black like the backlight showing a black screen and dim again. That's all it kept doing and would not reboot. I tried doing a kdz flash but the pc wouldn't even recognize my phone when I plugged in the usb. (Yes, the drivers were installed and it was working. Previous to this I have kdz flashed twice. Phone has to be in S/W Update Mode by first pressing power button and as soon as the LG Logo shows up on the screen, let go of the power button and hold volume down.)
This resolved my reboot issue since I couldn't do a kdz flash.

It got my phone working but still have unknown baseband and a question mark inside my battery icon.
**Update**
I read several threads regarding unknown baseband issue.
I've tried this method:
http://forum.xda-developers.com/archive/index.php/t-1332350.html
Since I already just did the first part by using the flash.bat file all I had to do was use the kdz flash. Unfortunately, my pc is still not recognizing my phone when I plug it in to the usb while in S/W Update Mode. I tried using this method above since the phone doesn't have to be in S/W Update Mode.
Outcome:
The LG Update Tool used in the method above kept stalling at 4%.
I read in another thread that this LG Update Tool doesn't work on Gingerbread. This LG Update Tool only works on Froyo.
So my next option was to use this method and try installing Froyo:
http://forum.xda-developers.com/showthread.php?t=1048274
This method just didn't work period. Since I don't have baseband or wifi working on the phone I can't get into market to download Rom Manager and I can't install File Expert which I have backed up on my pc. I already had the _ExternalSD directory so I made a sub directory /clockworkmod and another subdirectory /backup in the previous subdirectory. Made this on both the External and Internal sd cards and CWM tells me Couldn't open directory - No files found. So installing Froyo this way was out of the question.
I found this thread:
http://forum.xda-developers.com/archive/index.php/t-1037120.html
This is the stock Froyo version before the Gingerbread update as a zip file.
Unfortunately, when I tried to install the zip file from CWM it didn't work. I unzipped the zip file and found 2 .bin files which answers my question why CWM didn't install the zip.
I tried this method as well:
http://forum.xda-developers.com/archive/index.php/t-1332350.html
This method involves the flash.bat file to be done as a prerequisite before flashing to kdz. To my understanding, the flash.bat file fixes the partitions that most likely were screwed up on the phone and the kdz flash fixes the baseband (update/repair). I still haven't been able to get that kdz flash v1e to work simply because my pc won't recognize my phone into the usb when its in S/W Update Mode. I'm leaning towards the LG Update Tool to fix my baseband but I just need to downgrade to Froyo.
Don't know what else to do. I've been at it for 2 days and I'm seriously going to give up and just cancel T-Mobile.

If one of the methods involves installing apps, u can use adb to install them from ur computer without having to copy them to ur phone. But that's if u can get it into usb debugging mode.

When you installed the rom, there should've been an extra package for Google apps that you should have flashed along with the rom as well, but you did so many different things, I don't know what to say.

You don't need your backup, it won't fix your baseband if it's corrupted or at all because no one has been able to get this phone to independently flash a baseband and the only way is through running the Gingerbread update either with KDZ or the LG updater.
I also went through hell more than once when I bricked my phone a few times. The first time I spent almost 2 weeks at it until I fixed it with the help of others here.
I also had the KDZ update stop at 4% over and over again which drove me crazy with anxiety. I was desperate so, after a few of those 4% hangups, I decided to reinstall a ROM and kernel just to see if the phone's baseband had installed anyway. Well, what a surprise, it did work.
You should try KDZ update again and, when it stalls at 4%, leave it for about 20 minutes then install a ROM based on Android 2.3.3, such as Weapon 3, fix permissions then reboot. That's what worked for me once. Another time, I did the same but I installed MTK drivers first then ran KDZ which stopped at 4% too but it worked too.
Read post #20 in this thread about how someone else did that successfully: http://forum.xda-developers.com/showthread.php?t=1180177

Really starting to hate this phone. Can't install Cyanogen mod

My phone is very slow. Apps like text messages or even opening the app drawer takes 2-5 seconds. It wasn't like this when I got the phone. I RARELY use the phone at all because it's so slow. I use it mainly as an mp3 player, not a phone.
I uninstalled Go Launcher to see if that would help, nope.
I only have like 15 apps, uninstalled half of them, did not help.
So I tried rooting to test something like Cyanogen mod Nightly 10 to see if it would speed up and remove bloatware.
Rooted with Mega_Tron Windows. Took 10 minutes because the phone takes so long to reboot.
Get on rom manager and flash with the SPECIFIC LG O3D tool, not rom manager. Make back up.
Install Cyanogen mod.
What happens? Cyanogen mod spinning ball of death for 2 minutes then phone turns off.
LG screen get stuck. Not able to go to recovery.
So I have to use LG Mobile tool to reset the phone back to Gingerbread stock. Reinstall Rom Manager, GO back to my backup and try again.
What happens this time?
Spinning Cyanogen death ball. This time is actually makes it to the welcome screen. Then I click the app drawer and the phone turns off.
Stuck at LG screen. Can't enter recovery.
So now I must repeat the process for the 9th time. Yes 9 times, although I only typed here that I did it twice I have spent nearly 7 hours trying to get this working.
Please recommend a mod that won't fail like Cyanogen and will hopefully improve the speed off my phone.
My phone specifically is the LG Thrill 4g AKA LG Optimus 3D.
Rogers carrier, Gingerbread stock, v20c base band dec 2011.

you have to install wkpark 1.25a in order to use the cm10 roms............flash the attached files in recovery in order to make it work
follow these steps
(i recommand to refer xbsall thread and install his large partation bin file which comes pre-rooted and with twrp recovery)
1. install official ICS bin file from lg flashtool if you dont have
2. then flash the attlached file in recovery
3. after rebooting flash any rom that you want........it will work for you
Don't Forget To Press Thanks If I Have Helped

right now I can't even get to the main screen.
I recovered to Gingerbread with LG mobile tool and it just keeps looping at the rogers screen.
this is worse than before I need my phone working again.

just follow the instructions posted above by ptlsajan and you'll be allright.
You don't need to get to the homescreen to recover the phone, you should recover to an ICS kdz/bin (v28b or 30a) instead of GB, then you fastboot wkparks1.25a bootloader and recovery, and then you can install and boot pretty much any ics/cm10 rom you want.

get ICS, its like a totally new phone

oh yes :good:

What is the LG flash tool? Like I said I cannot even get to the recovery screen.
The LG Mobile Tool / LG recovery tool is useless now. Before I could reset the phone to Gingerbread and it would unroot and go back to normal. Now I cannot get past the Rogers loop screen.
Also when trying the LG Mobile Tool is tried to update to ICS and failed every time.

If it keeps failing do you see SW screen with GREEN dot in the middle?
So you go into download mode by adb(pc) ?

I never saw a green dot.
When the phone screwed up from root. I turned on it while running LG Mobile Tool. When to recovery and entered my S/N.
Then it started the download and update process. It installed Gingerbread and then says 'Continue to update to ICS' or 'Press stop if just want Gingerbread.'
If I tried ICS it would go halfway and say update failed or it would say you already have the latest version, EVEN though it told me there was ICS update.
NOW I CANNOT EVEN USE LG MOBILE TOOL. I am stuck at Rogers loop screen.

Firstly, be sure you use the same DLL as the one on your phone's IMEI ID sticker (for example P925 = P925 DLL), and after flashing the OS, try running fstrim - apparently bad TRIM garbage collection can wreck the phone (happened to me, now after trimming, it's faster). Also, if it doesn't work, get OMAP4 flash utility and remove the battery and plug USB in first then flash new BIOS (there's tutorial on installing the driver for the pesky OMAP4 bootloader), and then flash with LG flash tool as usual (power + volume up).

I am not sure what you are talking about.
I can't use the LG Mobile Tool anymore to go back to Gingerbread.
Where exactly do I start here?

I still need help with this.
I went to the sticky and some of the download links are dead.
The first download link contains a trojan.
I ran it through virustotal which detected it on Symantec and Avast which are good anti-virus. I use avast and scanned it and it detected. I also ran it through a sandbox.
So why am I being told to download viruses?

*sigh* Some rooting tools are false positive so I don't really trust anti-viruses. I use AVAST! anti-virus and ALL anti-virus cannot tell the difference between legit softwares (like Megatron or Super One Click) and nasty viruses. And here's the DLL (this one is from KDZ I extracted for P925).

Superoneclick nor megatron are detected as viruses on my computer.
This one immediately gets blocked after installing.
you sure about that?
The guy could have edited the link since so many people are having problems. could be key logging people right now.

Ah..... Try xbsall's unbrick guide. http://forum.xda-developers.com/showthread.php?t=1942836 and read carefully. I think you will have better chance of unbricking it. And I apologize for the response - what you said made me wonder about previous link so I looked and found another guide - by an obviously experienced ROM developer.

It's trying to alter Microsoft C+.
Not taking the chance getting keylogged and my bank information stolen.
I will wait until someone else post's another method to unbrick the phone.

Just use OMAP4 flash utility... -____- It doesn't even alter anything, I use this and other tools plentiful of times - if I was not to use those, my phone would still be bricked. And LG have been keylogging us for a while (look in /system/app - you will find MLT.APK there).

Remove the battery then plug USB in - that's the only way to get the tool to start flashing the BIOS update. When it starts, quickly insert the battery and reboot the phone after it is done. Again, carefully follow the instruction.
After it's done, start up your usual flash tool with volume up and reflash the desired firmware.

Yesterday I receive a OTA update, I refused it and then later when it came up again was going to refuse it, but my shaky finger touched the screen and started the update! next thing I know I have a $600.00 brick. if you hold the power button down It will flash the LG logo and then NADA, screen is lit but nothing happens. Hold the power button and after a few it will Flash the logo again but NADA again. If you hold the down and power button it will go to the reset screen, but again this will not reset the device.

Thanks for sharing. Testing tonight. I got the update to 5.1.1 from T-mobile and I did not know that if you try to root after the update, it will soft brick your phone and the user WILL NOT be able to do the factory restore with the power and volume down trick. The phone wont respond. My phone is pretty much dead. If this works, you will be my favorite superhero. Thanks!

I came back to say thank you again, you just saved my phone. Even my settings came back. You are the only person I was able to to find that had the right fix without running me around. I was not able to place the phone in download mode, but still followed your steps. The LG support too stopped at 24% and told me to remove the cable and the battery and place the battery back in. I placed the battery back and pushed the up volume almost at the same time that I inserted the USB cable on the phone. The phone went into download mode which I was not able to do before. Then the software continued to install the stock ROM. At the end, my phone rebooted and all my settings and apps were back how I left them before bricking the phone. Thanks forever.

It's Alive Again!
Thank you so much man. My LG devices have a history of dying due to flashing roms/recoveries but this is the first time a root messed up my phone. You saved me.

Thanks for sharing. Testing tonight. I got the update to 5.1.1 from T-mobile and I did not know that if you try to root after the update, it will soft brick your phone and the user WILL NOT be able to do the factory restore with the power and volume down trick. The phone wont respond. My phone is pretty much dead. If this works, you will be my favorite superhero. Thanks!

I came back to say thank you again, you just saved my phone. Even my settings came back. You are the only person I was able to to find that had the right fix without running me around. I was not able to place the phone in download mode, but still followed your steps. The LG support too stopped at 24% and told me to remove the cable and the battery and place the battery back in.

can you help me

Thanks! I followed the directions exactly and it worked perfectly
T-mobile had pushed an update to 5.1.1 and I reluctantly accepted. Then I tried to root using "LG One Click Root" application from XDA. It says it went through the rooting process successfully but when the phone restarts, it gets stuck at the LG boot screen. This fixes it!
So just FYI -- DO NOT ATTEMPT TO ROOT T-MOBILE LG LEON 5.1.1! IT WILL BRICK YOUR DEVICE.

Will this work for LG G2 VS980? verizon

I always get stuck
I have tried over and over and i always get stuck at 47% on the LG Mobile Support Tool and 49% on the phone. Help me please.

Hi, sorry for the time. I have been super busy these days. Anyway, I am glad you succeeded in unbricking your device.

Hi, sorry for the time. I have been super busy these days. Anyway, did you try this procedure yet? (I am just quoting someone else) "The LG support tool stopped at 24% and told me to remove the cable and the battery and place the battery back in. I placed the battery back and pushed the up volume almost at the same time that I inserted the USB cable on the phone. The phone went into download mode which I was not able to do before. Then the software continued to install the stock ROM."

I Did The Same Thing!

I also used "LG One Click Root" but on a Metro PCS LG Leon LTE and it went through the process and rebooted but got stuck on the logo.

I'm having a situation where the downgrade succeeds, but the phone still stays at LG logo and keeps booting.
If I connect the LG mobile support tool application, it states the phone is on 34510d firmware (eg, it does not downgrade, but remains in boot loop).
What I did was upgrade manually to T-mobile 5.1.1 and then wanted to downgrade to original stock rom.

Opens LG Mobile Support Tool, then "Connection To Server Failed" error. Stops there. No joy on this "fix"
Any suggestions why?

Will this unlock the phone as well ?

LG Leon H345 KDZ Stock Firmware Download brick fix works
LG Leon H345 KDZ Stock Firmware Download brick fix works
This works 100%! Please be aware that this is a more direct link to the KDZ Firmware! It will take you straight to the page that you need to be at without having to worry about your IMEI number at all! It has the KDZ Firmware image for all countrys and make and models of this phone!
lg-phone-firmware.com/index.php?id_mod=171
Also, be aware that there are more download options than what you see up top! I almost downloaded the wrong file for my phone this way! This is because it had the tmobile h345 leon right there uptop so I just clicked on it and started downloading it. However when you scroll down you'll see that there is a USA section that actually has several different versions for the same phone! Most notably the V10d, v10e, and the v10f! When making your selection look at the back of the phone behind the battery under neither the IMEI number and you'll see what version you have. Mine was the v10e, v10d is whats at the top under most downloaded so please make sure that you pay attention and don't make the same mistake that I almost made!
I also made another discovery. If you are unable to run the flash tool then that means that you need to download Visual C++ runtime Libary.
Another thing, when running the flash tool you may notice that it attempts to connect to a server and then has and error and says that it failed. It will happen as its flashing the phone and you see the bar moving percentage wise. However, do not be alarmed and do not close out of the app and try again! If you look at your phone you'll see that the car is still moving and that files are still being updated!
Also, even once it gets to a 100% it will still take a few minutes to complete so dont' worry about that!

This will not unlock this phone! However you can use the new version of KingRoot and that will do it!

Yes, actually I do. In my last post i stated that that does occur every time. However, you don't have to worry, just don't close the program and wait. If you look at your phone you notices that it will continue to update the even though it has that error, Once the phone is done updating and reboots. You'll see it updating the applications on the phone! An you'll be good to go!
So there IS JOY, in the FIX after all! Trust me, I just did it! :good:

Yes it does say that. A screen pops up with an OK button and tell you that the connection to the server failed and asks you if you would like to cancel the update. Just ignore it and wait and watch you phone and you'll see it update.
Also, on doing another phone i've noticed that the Read Phone command when you first press the normal flash button can cause the application to crash for some reason. However, if you just sick that part and press START then you'll be able to proceed as normally and it will work just fine!:good:
