LG Optimus T Recovery Help (bricked?) - General Questions and Answers

I'm not sure if this is the right place, but I couldn't find an OptimusT-specific forum so here goes:
I have an LG Optimus T that was rooted with Gingerbreak and it was working great. It was rooted however I never installed a custom recovery. I wanted to clean things up and started to remove the bloatware (using Titanium Backup) and apparently I removed something that was critical to the system, or at least the launcher.
The status bar appears at the top showing I'm connected to the mobile network, time, and battery status). The lock screen shows fine and allows me to unlock the display, when I plug a USB cable in I get the prompt to enable USB storage, but that's it. The rest of the screen is black; pressing the home button does nothing, and pressing the menu button doesn't bring up the settings.
This is where I'm stuck. I know I removed something that couldn't be removed, so my solution would be to simply install a custom recovery and then reflash the factory ROM. Unfortunately USB debugging is DISABLED and my menu/settings can't be opened, which means I can't enable USB debugging to connect to my computer and run ADB!
Am I out of options? I tried a hard reset (phone off, hold home/vol up/power) and it resets the data, but I still don't boot into to the launcher, just the black screen.

The Optimus T shares roms recoveries etc with the Optimus One. That's where all us Opt T owners are

I suggest you install a custom recovery and make a nandroid backup prior to "experimenting".

Yeah, well I think I learned my lesson today.
Oddly enough, I found that post and followed those steps before seeing your reply, and IT WORKED!
Thank you. Now that I know where all the Optimus T resources are, I can start to look for what want (unbranded stable ROM with no gimmicky eye candy or major tweaks).

Hi I have the same problem the only thing is that I get no USB debugging mode (and can't turn it on in any way).

[Q] LG MyTouch Bricked! Please help...

I went to clockworkmod's website and downloaded a cyanogen mod rom that they claimed was compatible with my device... Now the thing is bricked and I can't seem to recover the original rom... Anyone have any suggestions?
What do you see when you try to boot?Please explain little bit more. I have E739 too and CM7 works good for me.
go to the telephone service
When I turn the phone on the android on the skateboard shows up and that is all you see. It stays at that screen for about give minutes and then the system crashes.
I've tried every key combo I can think of to get it to go into recovery mode and or into clockwork mode, and nothing...
I've had that problem before. You didn't wipe data,cache and dalvik cache before installing CM7..you need to get into CWM recovery.. *From T-mobile website* To perform a master reset using hardware keys, follow these steps:
Turn off the phone.
Press and hold the Volume Down and Power keys.
Wait 3 seconds and press the Back and Menu keys.
Note: If you see the LG logo before pressing the Back and Menu keys, the reset hasnt been completed and you will need to restart.
Release the Power/Lock key after you see the LG logo.
Release the remaining keys after the LG logo flashes (blinks once).
The Android Unpacking screen appears.
The phone will restart and complete the factory reset.
Note: If you unintentionally press the Volume Down, Volume Up and Power keys simultaneously, the phone will display a circle icon with two arrows and 'S/W Upgrade, Please wait while upgrading...' message. You will need to pull the battery and restart

Hopefully you backed up your ROM before installing CM7..in CWM recovery use volume keys and power button to go to Backup/restore and then restore to most recent backup.

Moving to Q&A
@DarkLP: Already tried that, and it doesn't work on this model phone. I did wipe all the caches before restarting too. Not quite sure what to do next...
Timing is precise in getting into recovery, keep trying eventually you will get there, I have the same phone.
I bricked my phone too yesterday, I am really sad now. I was panicking and trying to save my phone but all it does is go into the LG logo, blinks once, and shows a half cut-off LG logo.. I tried doing that master reset thing.. are you sure it works? I'd dedicate all my time just to unbrick my phone

			
				
I was able to unbrick my phone the other day using Android SDK and the command prompt. What you need to do is have a backup of your ROM saved on your sd card. Use the command prompt to put the phone into CWM recovery mode and then choose the backup/restore option on your phone.
If the backup is stirred in the correct file on your sd card then the recovery program will automatically detect it. From there choose the file you want to install and then activate the restore process.
You should be good to go after that.
That is what i was going to say.
Ahaha I couldn't be any more happy, I went into recovery using that button combo trick, flashed C7 and a Kernel and Google Apps (you have to flash google apps if you want them) go to cyanogen mod wiki and find g-apps there. To get your cyanogen rom just google "lg mytouch roms" and you should click the android central link and then scroll down and someone posted the files for it. Only thing that went wrong is the Camera doesn't work..
It should be same as Dream G1, download a .pnh and Fastboot
Low end cheap bro.....
Tmobile Customer Service
TMO's customer service is pretty good. Call them and tell them you were installing a non market piece of software (true enough) and that your phone won't power on. They will walk you through some steps that might get you going and if not they will offer to replace your phone if it is still under warranty. I sent my defy back several times whaen I was learning to flash ROM's. Then, remember to wipe everything before you flash anything.
OK that doesn't make sense. once you root your phone, warranty gets voided.
yes i'm sure, I've had the same problem as you did. you need to keep trying.
so did you fix it?
If you are talking to me, yes I did manage to fix it and flash C7. But I want stock ROM back, anyone have the files and directions?
Now the phone wont boot into S/W mode and wont power unless powered on after my pc froze during the update

[Q] Razr HD Problem (Need help ASAP Please!)

HI!
So for the past couple days my Razr HD has been going crazy. When i turn it on it comes up with almost every single app saying "Unfortunately .... has stopped. The first one or the one that pops up the most often is like .gapps which i believe is the google apps? But once these messages pop up they don't stop, making it extremely hard to get around on my phone. Also about one minute in my homescreen wont work so im stuck in settings or something. Another thing is that it will restart by itself if i leave it alone for a minute. And when I try to wipe it/factory reset, it doesnt work, i come back to everything being the same! ive tried every single way. Fast boot loader, Recovery mode, from settings, turning off restore in setting. Please help! I know it must be like some kind of virus and i really need help, im not the most techy person out there. But my brother is, so if you have something complex, im sure he'll understand.
Thanks

You must have tried a cwmr/twrp restore to a previous backup or all the way back to your 1st backup?
I sounds like a corrupted ui.
Rsd lite restore to the newest stock build.
You talk as if your boot is unlocked-so it cannot be relocked.

If you are careful not to use the xt907 xmls, I have a guide in my signature-stock restore. All the steps apply to you. You can browse the driod/developers site for the right hd xml for you.
Do try the safeboot first.
You have a locked boot right?
Always choose the latest xml.

Just use RSD Lite to restock your phone. It will solve your problem...
1. Download and install RSD Lite 6.1.5 - https://dl.dropboxusercontent.com/u/...ite_v6.1.x.zip
2. Make sure you have installed latest Motorola Device Manager and drivers on your PC - https://motorola-global-portal.custh...81/action/auth
3. Download XT925 stock firmwares (Retail.DE for example...) - http://sbf.droid-developers.org/phone.php?device=6
4. Put the phone in AP Fastboot (Turn off your phone. Press and hold the following buttons at the same time until the screen turns on 1) volume down 2) volume up 3) power. Press Volume down until you reach the AP fastboot in the list. Press Volume up to select) connect it to PC cia usb cable and start RSD Lite
5.(optional) When you extract it and load the rom in RSDLite if you get FLASHING FAILED ˝getvar´ you'll need to edit rom file and delete line with ˝getvar˝ strings and <step operation="getvar" var="max-download-size" />
<step operation="oem" var="fb_mode_set" /> strings also.
If your phone is Droid Razr HD XT926 download it's roms from same site in step 3. instead for XT925. http://sbf.droid-developers.org/phone.php?device=5
Let me know how it went... If you have any questions...

Black screen and nothing else...

Lets make a long story short, i just got my OPO, as an advanced android user i desided to put
ParanoidAndroid 4.6, but before I installed custom bootloader (TWRP) and rooted it. Since i am installing new ROM i did a backup and then i needed to wipe my device, by accident i wiped everything from my phone, including backup and new ROM. I was left with TWRP (It is my 1st android phone without sdcard so i started to panick), then i started it in fastboot mode, to check if I can copy ROM again from my pc, but it didnt work. Then i went to restart options in TWRP and choose restart in recovery mode, then my phone turned off. Apperently it did restart but now my screen is just black and I cant do anything with it. I was holding power button, then with volume up, then with volume down, no result. When i connect it to my PC i hear sound that phone is connected but still nothing is happening. Please help me what should I do. My guess is when i pressed to restart in recovery mode, it wasn't meant to be the custom one, so it tried to open one that dosen't exist. My phone was charged 40% when i was doing that.
Note1: Unknown USB Device (Device Descriptor Request Failed), this is what i get when I check Device Manager.
Many suggestions were made so far none of them help. Hope someone will help me here!
First, TWRP isn't a custom bootloader, it's a custom recovery. The phone can't 'open a recovery that doesn't exist', it opens whatever recovery you have installed at the time. Make sure the phone is powered off (hold power for about 10-15 seconds), then try booting into recovery again (hold power + volume down).

Looks like you're using windows from the looks of you writing Device Manger so if you can boot back into fastboot then you're still okay!
Download this then just use the Flash CM11S option and it should bring you back to life.
Tool kits are amazing bro. Even as an advanced user myself they are still my favorite tools to use.
There is another problem

My friend you're in a bit more trouble than I think you realise you're in. Your device is showing up as QHSUSB_BULK in Windows, which means it's technically bricked. I believed you can save it though, have a look in this thread, you're gonna need to read through it all to find the solution you need. Let me know how you go.

[Q] im in dire need of help please!

Here is the rundown. I have the d 850 LG g3. Was planning on unrooting phone from towel root and rerooting it using towelroot once I found the mod I wanted. I have the latest version of twrp loaded as well. On my way home from work yesterday I was riding my motorcycle and listening to music, all the sudden the music stops so I pull over to see what happened and look to see that my phone has somehow opened twrp. I get home and try to reboot phone and it loads right back into twrp. I did a backup. Restarted phone to same results. I factory reset phone thinking that would work. NOPE. Straight back into twrp so I plug phone into computer to see what's on it. It appears all my games music LG backup etc is still there's why can't I get out of twrp. Could I have accidentally wiped everything while in my pocket? Can I fix this problem or do i now have a $500 paperweight? Please please folks out there in xda land help me out. I've got experience in rooting with my htc m7 so am familiar with this stuff. Any help would be greatly appreciated. Thanks for your time.

Somehow your rom partition/system seems to be corrupted. If you want to try and save your data, Please copy the downloaded version of your current rom and dirty flash (flash without wipe) and try to get back into the system. If you do not have your rom in your internal memory, try adb sideload or try to copy it to your external SD card and install from there.
You can also try to copy your stuff over to the external SD card using the file manager in TWRP and then wipe and install your rom.
If none of these wor, you still can flash factory image by process defined in the this thread: http://forum.xda-developers.com/att-lg-g3/general/unroot-return-to-factory-stock-att-lg-g3-t2820827
I believe you can still rescue your phone. Please let us know how it went.

The rom is normally a zip file.
If you already tried to flash a rom (other than your current one) I suggest you try the "back to stock" thing that was referred in my last post. If you have all the drivers in place and do the process correctly (preferably from a Windows 7 laptop), Your phone will be burst back to life in no time.. Good luck..!!

That is exactly what you want. You are now in download mode. So please proceed to next step (i believe the next step is on the laptop).

Device manager wont "pop up".. you need to pull it from control pannel. Once you confirmed/changed the port to 41, i believe you can pull the usb, wait for 5 sec and put in back in. Follow exactly as instructed in the thread and you should be fine.

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 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!

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, 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:
