Hello and thanks for clicking in!
I am broadcasting an SOS to anyone who may be able to help.
I am also aware that because of the recent stock OTA which I have already installed (build 35b), this may be game over, but if anyone has any ideas, I am ready to try anything.
A brief history: I was jumping between SkyDragon and Jasmine and at one point, my phone was acting funny so I wanted to go back to stock.
I flashed stock using kdz to 24b and everything was going fine for a bit until I updated to 35b OTA (big mistake).
Now my phone is completely unusable - for awhile I could get it to work for an hour or so by factory resetting, but any time I installed any apps, system processes would constantly fail, display would become unresponsive, and at one point, all audio just stopped working (headphones, speaker and ringtones, notification sounds, alarm, even bluetooth). I tried to flash stock again and now my computer won't recognize Android MTP device. I have tried all the LG drivers I could find, Koush's adb drivers, Verizon LG drivers, and no matter how I try to get my computer to recognize my phone I always get this error:
'Device driver software was not successfully installed:
MTP USB DEVICE FAILED'
I have tried TOT and KDZ methods to downgrade to stock and nothing will work because my computer won't recognize my phone.
Does anybody have any advice?
Thanks in advance.

I have been through and tried both methods thoroughly, including going through it with a friend. It seems that the root of my problem seems to be that I can't get my phone to connect MTP to any computer. It just won't get recognized by any computers. I tried on my desktop and laptop and my friend tried on his and his roommates machines. We put our heads together and still couldn't figure out how to get it work.
He suggested that it is a kernel/baseband error as I had installed a custom ROM with its own kernel and when flashing back to stock, it was conflicting with the custom kernel that was on the phone and this is what is causing my phone to malfunction so miserably.

Hi again, well try then to ask over the Q&A thread. Right here:
Good luck!

Hello, I recently decided to root my phone and place Cyanogenmod on it. When I did that I realized my radio was no longer working. In an attempt to just get back to a working phone for the time being I flashed a rom that I believe was just for the Nexus S and not Nexus S 4G. Due to my stupidity I am unable to communicate from the device to my computer using USB. When I attach the device to the computer nothing happens. The device does not even appear in the device manager. I have tried on multiple computers as well. On top of that the rom seems to have put me back into the stock recovery. If anyone could help me figure out just how to get USB working again I would be very appreciative.
I should note that I can still transfer files to the phone using the sd card or via ftp.
Thank you for your time and help.
Change the USB cable?
Yes, forgot to mention that. I have tried 2 cables both of which work on other devices.
What if you hold in the middle of the volume buttons (i.e. both up and down at the same time) and keep holding, then plug in to your usb port? It should come up as download mode. If it will do that you might try using Odin.
Or try a different machine perhaps?
are the drivers the same for the S as the 4g?
do you have clockwork on the phone or have you tried to run recover by holding volume up and power?
just throwing things out.
Hello, I appreciate any and all suggestions and help.
I have Odin downloaded and installed, but the computer can not find the device so Odin can not do what it needs to do. This is even the case in download mode.
In terms of recovery I am on the stock recovery. I was on clockwork but made a small mistake and now am back to stock.
I know if I can just get the computer to see the phone exists I can fix it.
If you can find the full OTA package for NS4G, you can try putting it on the SD card and flash it via stock recovery.
Also another thing worth trying is connecting the phone to an Ubuntu machine and see if it's detected or not.
I have tried looking for the original full OS. I will continue looking, but the different OS thing is a good idea I did not think of. I will attempt that now. Thank you.
I installed Ubuntu and the Android SDK and Ubuntu was unable to see the phone as well. I am going to keep searching for the original firmware to see if that will fix it. Thank you for your help so far, it is greatly appreciated.
I have found the only rom my phone will accept now is
Android 2.3.4/GRJ22/KRKC1 Radio/KA3 Bootloader
Which is for the M200 variant. This apparently the Korean version.
Hi all,
I've got a Nexus S 4G CDMA Sprint phone running Stock ICS 4.0.4 IMM76D.
My bootloader is unlocked from previous roots and whatnot.
My problem is that my phone is not being recognized by my computer at all. We're talking complete nonrecognition. No yellow triangle in device manager, no pop-ups, nothing. This phone will just not be read by my computer! I've tried different cords, different computers, re-installation of drivers after resetting my computer, installed PDA net, did a factory reset on the phone, I've literally been on Google for hours upon hours upon hours trying to figure this out and can't figure out why the computer is not recognizing the phone and why the phone is not allowing me to put it into usb mounting. It is however, charging via the computer and wall plug. I can get into stock 3e android recovery, fastboot using V-Up and Power and I can get it into download mode. It is NOT recognized in any modes by the computer nor other computers including my Linux box. The phone states that the usb control initializes but then ends a moment later. I am thinking this is a hardware issue but that leaves me with two issues:
If I was to go to Sprint to have it fixed they would realize my bootloader was unlocked thus voiding the warranty and I'd feel like quite an idiot at the store
If it is hardware related why is the charge working on the device.
I have also tried to bend up the usb plate to make it touch the pins better but that did not help at all. I am at my wits end and really need some help here, I've done everything I could find on Google and here plus more. I want to just return it but with the bootloader unlocked this is really not a possibility. I am looking for help to either become able to lock the bootloader without it having to be connected via the computer so I can then get it fixed if it is hardware related or if I can get the darn thing to be read by the computer once more. so yea, this is where I am at and I would appreciate it so much if someone could help me out, thanks guys!!!
Wireless adb in playstore should help.
Sent from my Nexus S 4G using XDA
That would be perfect! Only problem is that it requires root access on the phone which I am unable to obtain because I cannot access the phone. Is there a way to root the phone without having to connect it via the computer? Something like an update.zip with files able to be flashed through android recovery 3e? If I can get root access than wireless adb would be perfect.
*ultimately if I could remove signature checking in Android Recovery 3e that would work so I could in turn try to root the phone and install a different recovery to then try a different rom to see if that in turn fixes the issue.

You might be able to download your rom of choice and rename it update.zip. I'm not sure if it will flash though....someone else chime in if I'm wrong. You can use wireless file transfer if needed.

Yea I've tried that, everything gets shot down by the recovery with a E:Signature Verification Failed. Thank you for your help so far but I don't think this is something that is going to be helped. I've put in a ticket to Samsung for a repair under it's warranty. In the past I've sent in a rooted phone and they've fixed it so I think I'm going to give that a shot. Just don't want to be without a phone for 2+ weeks.
Well good luck...you are running stock unrooted so it shouldn't matter. It is a dev phone for damn sake. Sorry couldn't help.
Sent from my Nexus S 4G using XDA
Well if you want to download a custom rom... Since you are on this forum. Download any rom (preferably CM9 since its quite good from my experience). Flash the stable version and wait till everything is completed. Now when you flash make sure you download a recovery...eg ClockWorkMod Recovery from google market. You should now have a custom rom installed and download wireless adb as chappy said. See if that works
hello,
I hope someone can help me with my AT&T LG Optimus Pro G phone, which I have royally screwed up.
I was experimenting with the cyogen mod and after installation I installed the freegee app and once the cwm recovery was installed, I decided to go into the recovery by holding down up volume and power button.
Once I was in recovery for CWM i couldn't exit out, and the phone constantly booted into recovery after every reboot, even if i took out the battery, and powered it on.
I tried reflashing the cynogen mod through the sd card, and even though I would get success message the phone would still reboot into the cwm recovery.
I started doing research on the internet and i found file exitrecovery.zip that could be used to possibly get the phone out of the cwm recovery.
After installing exitrecovery.zip, I rebooted the phone, and now I have complete black screen. There are no light, no hints the phone is even turning on, and I can't get into recovery( or at least I can't tell). The only thing now is that when i connect the phone to the computer the window tries to install drivers for the device, and eventually prompts to insert a CD for LG drivers. I already have LGUnitedMobileDriver v.3.10.1 connection drivers installed from their website.
Please help, I am really stuck here..... and have no clue what to do. I am fairly new with rooting and modding, and I am extremely miserable.
The phone is still under warranty from LG. Anyone if all else fails, and since the phone has no screen or lights, whether they would replace it?
Attaching the exitrecovery.zip that I used.
sobbing....

hi, thanks for your reply. Again I very much new to the rooting and android OS tinkering, and nowhere close to an experienced user.
I tried to use google with your information in regards to how to use flow ROM with expansion.exe, but did not get any leads.
I would appreciate if you could elaborate more on this process.
When my phone is connect to the computer via usb is is constantly trying to install drivers. I had already installed LG usb connection drivers in the past and it was successful. It almost seems it tries to install driver yet fails after receiving no input from the phone, and then request LG CD with drivers.

Try to find driver on the web-site of producer. Set them. Overload a vehicle in Bootloader. In the controller of devices on компе must be determined your device. Then on a computer start sewing - .EXE.
Did you get this problem resolved? I have the exact problem with the exact phone!!!
thank you very much
I'm at a point where i need enough help that im starting a thread about it.
How it started:
It all started when i restarted my G5 with Quick Reboot [ROOT] (AntaresOne Studio ) because it was lagging/slow.
After restarting the phone would not boot. It would always go to the Optimizing XXX of XXX apps, finish, restart and optimize again.
What ive tried:
I factory reset my G5 by using TWRP and formatting the data partition.
That allows me to use the stock? G5 ROM, but one huge issue, is that if i turn on Wifi, the phone reboots within 2 seconds to the tmobile screen and gets stuck.
It fails to reboot after that.
My phone has retained root. I was able to verify that by downloading Root Checker and it confirmed that i have root.
SuperSU also worked properly and SnapChat fails to login because it is detecting that i still have root.
I have been rooted for several weeks without any problems fyi. I have not updated my phone at all.
I was hoping i could unroot and flash the stock unmodified? tmobile ROM,
but in download mode, LGUP detects the device as "unknown device"
and if the phone is booted, LGUP does not detect it, instead it gives me a drivers need to be installed warning.
(The drivers are already installed, because i installed then when originally rooting, i also reinstalled everything the root guide suggested anyways)
At this point i am clueless as to what else i can do.
Currently i can use the phone more or less fine but i can only run on data.
Play store has trouble installing apps via data so i tend to download and install APKs directly via file manager.
Thank you for any help and insights in advance.
Well, I would suggest flashing the 10D kdz to get back to stock. However you need LGUP working to do that...
It sounds like a driver issue... I would uninstall the driver, reboot, reinstall, and try again.
As for uninstalling the drivers, that is easier said than done sometimes. You may need to manually remove the driver files if the uninstaller does not.
You may want to use something like Revo Uninstaller to monitor the install and then do an uninstall again.
If you have another computer, doing it on that computer could be an easier route, heh.

SO i tried it on my mom's windows 7 desktop, and it look slike all the drivers installed properly, however when i run LGUP, same thing happens.
It shows up as "unknown device". The other LG software also doesn't detect it. I can factory reset the phone and it stays rooted, but the broken wifi is a huge issue.
I'll keep try thou. Your driver issue idea seems valid but idk what is happening at this point :/ I used to love this phone and LG (coming from the S4) but no so much anymore...
The chinese brands will take over at this rate lol. Axon 7 is compelling. Again, Thanks for the advice
EDIT:
I fixed it. Issue was due to build.prop. because the file was modified it caused the software to not detect the phone properly apparently, so putting back a clean stock build.prop allowed LGUP to recognize the device.
Hi,
Yes, I know, there's a million topics about this and I'm pretty sure I tried them all!
Long story short: been running Lineage OS on my Tab 2 for a while but it's been sitting in a drawer. Saw a video about using old tablets for emulating retro consoles and the Tab works a dream for that. So I bought a Bluetooth controller for better gameplay but it just wouldn't work under Lineage so thought I'd flash the original ROM back onto it to see if that would work. I'm not a n00b, but haven't done it for a while so thought to be safe I'd follow a guide. All seemed to be working well when Odin crashed and left me with the Firmware Upgrade Failed error.
I've been trying for about four hours to get it back, but having no luck. I've tried the latest version of Odin, as well as the old 1.7 version I was using; tried Kies, tried uninstalling Kies; tried uninstalling the stock drivers MS installed when connected, no go. Interestingly Odin doesn't seem to see the Tab at all now, so I tried the UniversalADB installer, tried installing ADB drivers as well as Samsung drivers manually, but nothing works, it just sits at "connecting" but never actually does. Also tried different stock ROMs to no avail. I think my issue is with the ADB drivers, just don't know how to fix it.
I don't know what to try now. Any advice?
Using MS Surface Pro (2017) running Win10.
Not allowed to post screenshots, but do have some.
Thanks.
How is the tab behaving after this crash?
Can you use the tab as usual? But you are still in LineageOS? If Yes, what version of LineageOS?
Can you still get into Recovery Mode? If Yes, what Recovery and version do you have?
Download Mode seems Ok, but not Odin at the PC end. Correct?
The more info you can give the better. Also if you prepared the tab in any way other than just entering download mode.
Did you enable USB Debugging for example? (but I'm not sure how important that is)
Or wiped anything in recovery?
I'm not sure if I can help, but surely there must exist someone here that can. I'm new to the android world, but used to work in IT Support and Network Administration.
And 100 years ago I blogged with Blogger, but sat and amended the xml-file to get the design I wanted more than creating blog entries
Anyway, I hope it gets sorted.

Hi,
Thanks for your reply and sorry it's taken me so long to respond; I've got several health issues I have to work around!
I can't get into the OS at all, it's just stuck at the "Firmware upgrade..." screen and there's nothing else I can do with it.
It was rooted and I was running TWRP recovery, but can't access it at all now. I did a wipe in TWRP but was still able to boot into it before I ran Odin. Odin worked fine, then it just stopped for reasons unknown and now there's nothing I can do with the Tab at all.
I see this in Device Manager: samsung mobile usb cdc composite device. Have tried manually installing driver but nothing seems to work.
Have tried it on my Mum's Win7 machine, but to no avail. I really need ADB drivers but I can't install them without turning on debugging on the Tab and I can't do that because I can't get out of this blasted error screen!
There's literally nothing else I can say about it as this is all that's happening.
Annnnd, now it doesn't seem to want to hold a charge. :crying:
Thanks again.
I've tried following a few tutorials, but I can't get past the ADB issue. Does anyone know of, or can link to, a solution to this please? I really want my Tab back!
Thanks!

Maybe a longshot, but you can test if this free version can access the tab:
https://www.tenorshare.com/products/reiboot-for-android.html
No use buying if it can't.
But since Device Manager sees something it's worth a shot.
Do you have to longpress power button to turn it off?
If so... when the screen goes off, have you tried to quickly let go of the power button and immediately press it again together with Volume Up?
Or down, for download instead of Recovery.
With my P3100 it was much easier with no charger plugged in...
Edit:
Tried the software and my tab is OK, but no connection established anyway. Only result was that I couldn't access tab in File Explorer and MTP state... only PTP.
In Device Manager I got a new Android Device: Something like Google Nexus ADB... sorry but I uninstalled it directly without noting exact name.
Replugged USB cable and MTP working again.
