As the title suggests, bootloader unlocked no problem, tablet was connecting to ADB at the time, tried to flash recovery which as far as I can tell was not successful (I can't boot to recovery, get the injured Android icon), now I can't connect to ADB (get the "List of devices attached" result). So I'm completely stuck, can't move forward, can't go back to stock, what do I do?
Edit: Apparently it's an issue with my PC, my wife's PC worked fine, why it worked to unlock the bootloader and then stopped I have no idea. Can anyone link me to a solution to get ADB working on my PC again? I tried removing/re-installing drivers, rebooting, you name it, no luck.
With your device booted into recovery or the system do you get anything in device manager? If you get a device with a yellow exclamation mark, right click it. Go to where it allows you to choose a driver from a list on your computer. Select adb android composite (or something like that)

Thanks for replying.
So before unlocking the bootloader, with USB debugging enabled I could get the tablet to connect using the ADB driver and could access it with ADB but could not access storage for file transfer, with USB debugging disabled and switching the driver manually to the MTP driver I could access storage but not ADB. I have had other device drivers installed on this PC for my Galaxy phones, I had issues initially with the tablet connecting but showing a yellow exclamation mark, then I removed all of the Android USB devices using USBDeview and installed the 15 second ADB tool to get it working, I'm on Windows 8.1 BTW.
After unlocking the bootloader, with USB debugging enabled I cannot get the tablet to connect using the ADB driver and but it does show as an ADB device with no yellow exclamation mark, I just get the "List of devices attached" result and anything that tries to access the device via ADB hangs or fails. I can still switch the driver to MTP and access the storage just fine.
My wife's PC is a Win7 box and has never had android drivers or ADB installed, I used the 15 Second ADB installer on her PC and the tablet works for ADB and storage access with USB debugging turned on, so there's something I'm missing that needs to be wiped out or reset on my box.

I can't connect to my phone with ADB. I've tried with SE's adb drivers and the ones from Android SDK, but none of them work, it starts the daemon but it's unable to recognise any device.
I'm on Android 2.1 with "USB dbg" enabled. My system is a XP64 SP2 with the correct drivers. Any ideas?

Does it not recognise it at all or will just not mount?
I can mount it, but if I type "adb devices" in cmd it returns a blank list. I've switched of my firewall and antivirus, but it does not resolve anything. I've seen that when running adb, it loads two instances of adb.exe and then kills one, also when trying to root with SuperOneClick it loads and maintains two instances.
I've had trouble with it most of the day but seem to have sorted it now, but it does show with adb devices for me so not sure.
Once you update to 2.1, you need to update the drivers.
The easiest way is to install Sony Ericsson's PC Companion (and update): http://www.sonyericsson.com/cws/support/softwaredownloads/detailed/pccompanion/xperiax10
I was wondering about this too. Sony Ericsson Update Service would detect the phone in flash mode, but not ADB or SuperOneClick. Once I installed PC Companion, it was fine.
Check your Device Manager. I'd bet you have a yellow exclamation mark.
I cannot seem to get Windows to see the device when in USB Debugging.
I've installed drivers from http://www.lg.com/us/support-mobile/lg-VS985-Metallic-Black (v2.18.0). Uninstalled and reinstalled. Switched back and forth from PTP to MTP and back again.
Restarted ADB a few times but device manager is still showing drivers not installed when I switch to USB Debugging. As soon as I turn this off it will connect, but of course I cannot see my device in ADB.
I really need to update TWRP as I'm currently on 2.8.0.
I'm an idiot.
Solved with ADB drivers...Sorry...
My end goal is stock lolipop rooted.
I botched a flash and now I cant get developer mode / ADB working.
When I started, my tablet was stock ROM, towelroot. I connect tablet in developer mode, flashed dual recovery and everything was great. I copied the pre-rooted lolipop ROM to my SD card and flashed it. HOWEVER instead of turning off the device, I selected reboot from recovery. This resulted in boot loop.
SOOOO, I figured no worries, just flash old ROM and try again. So did this:installed Androxyde Flashtool
opened XperiFirm
downloaded 1276-8392 and 1274-8801 (I've tried the rest using both ROMs btw)
Tools>Bundler>Create>Selected folder>selected SGP312 for device
For branding I entered the above ie 1276-8392
For version I entered the ver ie 10.5.A.230
Flashmode>checked boxes to wipe everything
The flash goes through without a hitch. Under about tablet, I see
Model : SGP312
Android Ver : 4.4.2
Kernel : 3.4.0-perf-g32ce454, [email protected]#1
Build Number : 10.5.A.0.230
I activate USB debugging and unknown sources, connect to USB and Flashtool returns: Device connected with USB debugging turned off
I went into device manager and found the MTP driver. Also of note, the device ID is: USB\VID_0FCE&PID_5194&REV_0228
I downloaded Sony's ADB drivers, tried to manually update device driver and windows7x64 kicked back driver is not for your device.
I edited the INF to include the hardware ID exactly as it appears in device manager and tried again. This time windows let me load the driver. It shows up in device manager as 'Sony sa0107 ADB Interface Driver'
HOWEVER, Flashtool is still giving me the same MTP message and if I cmd prompt "adb devices" I get nada.
Is there a way to verify developer mode on the tablet? What else can I try? The tablet gives me a notification when I connect 'usb debugging mode connected, ready to install software'
Thanks!

I had a very similar problem in 2014. I do not want to discourage you, but at the end I send it back to sony for a repair. They gave me a new tablet and said that the mainboard was broken.
Nevertheless, there is a thread in Sony cross device general, where people like you end up: http://forum.xda-developers.com/showthread.php?t=1849170
You can try and search for help there, maybe you have more luck then me.
Its odd... ADB was working and stopped after flash. Is this what you had or just no connection from the start?
Sorry, I misread your post. I thought your tablet would not start and you could not get flashmode working. Sorry for that.
What you could try:
1. Be sure you actually activated USB debugging in developer options
2. When you connect the device, you should get a prompt on the tablet to allow usb debugging from that computer
Maybe try "revoke USB debugging authorisations" in developer options and reconnect
3. Install the drivers from flashtool/drivers/ or install sony pc companion. Delete your old driver from device manager.
4. try switching between MTP and MSC mode in usb connectivity menu
Since ADB worked before it was probably no driver problem. Now you cannot be sure. Most probably you tapped away the said prompt of allowing usb debugging when connecting.
If none of this helps I don't know of anything more. Maybe try different usb ports or even computers.... Or try to flash again

UGH!!! I'm a jacka$$. I totally forgot about that menu/setting. fixed instantly.
Ive been trying to root my device for over a month now, and i havent had any luck. Ive used different USB drivers software and Hardware. Ive used different cords from stock to the ones from my job and friends yet i still have failed to root it. ADB reconizes my device no problem when its booted up, but as soon as i boot into FASTBOOT mode my computer doesnt reconize the device. What am I doing wrong or am I doomed to have an unrooted device?
I had the same issue with windows Vista.
Grab the attached file. Unzip to wherever.
Plug your phone into the pc IN fastboot mode. Open Device Manager.
Find the messed up driver, usually indicated with a yellow symbol in the list.
Right click it and update driver. Don't let it auto search for one. Manually tell it where that driver is that you just unzipped. It will show a list and chose the android bootloader one. It will warn you stating it's not correct, ignore that warning.
If you need more detailed instructions just holla.
Peace.
Did you try fastboot commands when in the bootloader? Remember that adb is only for when the device is booted up normally. Just making sure...

open device manager, you will see the device with the yellow symbol, right click and select update driver software
after browse my computer for driver software --> let me pick from a list of device drivers in my pc --> android adb interface! . click on yes. this worked for me
Alright, I've tried installing the drivers from Verizion and also using the drivers from the Android SDK and either way I have the same problem. ADB devices shows my phone, however whenever I try to push, pull, or reboot (the only commands I have any use for atm) the command prompt hangs like it's trying to access the device but no matter how long I leave it the device will not reboot, nor will any files appear in the correct folders on either the device or my computer.
I'm trying to root my phone and this is a pretty major roadblock.
Note:
USB Debugging enabled
ADB drivers installed
Phone shows up on "adb devices"
There is no error or any other output in the console. The best way to describe this problem is that ADB hangs.
I'm running Windows 8.1 and my phone is running Android 4.1.2
Also, I don't know if this is normal but, In order to get the notification that "USB debugging connecting" I have to use the internet connection option on the phone. When using MTP, Charge only and PTP that message doesn't appear and I don't see an ADB device show up in device man.
Things I've Tried
Uninstalling all Android drivers and redownloading/installing them after restart
Restarting my phone multiple times
Running adb kill-server / adb start-server
Changing USB ports7
Thanks!
Try installing drivers from LG. This seems the right one but double check:
