Just enable USB debugging and type in 'adb devices' from command prompt. (For adb to work you need Android SDK)
If it reports as some device as detected, things can be worked out.

Why don't you flash stock ICS firmware in flashmode(via flashtool)??
Have you tried flashing stock rom with flashtool?
You can also try (re)mounting sdcard in cwm recovery or with adb.
In cwm it's located in mounts and storage --> mount sdcard.
When you connect your phone to pc, do you see that "usb debugging enabled" notification?
If not you have to enable it from developer options. And when you try to do something with adb, does it give any error message, such as "device offline", "device not found" or "waiting for device"?

i have tried remounting in cmw but nothing happened about adb none response, there is no error. i have checked usb debugging while connecting with pc in mobile no such words "usb debugging enabled" its just charging thats it nothing more than that
your problem is that ur drivers are crashed because of some weird reason..
Download usb deview at http://www.nirsoft.net/utils/usb_devices_view.html#DownloadLinks
unplug your phone..
now unzip the app and run it..
in the vendor id tab search for drivers having id as - "0fce"
Select ALL of them and uninstall them by right click --> uninstall selected.
remove sony pc companion.
restart your pc..
download latest adb and fastboot drivers here : http://rubenalamina.mx/download/525/
simply run the installer..
default install directory is C:\ADB
now turn off usb debugging and then connect your phone.
let it install mtp drivers.
now download flashtool https://unrestrict.li/flashtool
install the flashtool.
(optional but still recommended) disable antivirus and firewall of pc
go to install directory of flashtool and locate folder "drivers"
open it and run the installer.. you will see a window asking which driver to install check the following items:
-xperia p, u, sola, go, drivers,
-fastboot
-flashtool
when its done unplug turn on usb debugging and go to installed directory of adb, press and hold shift key and then right click anywhere in that folder..
select open command prompt and pass this command:
adb devices
you should see at least one device connected.
if yes you are succeeded and fastboot will work too.

bro i cant find those sony adb in device manager im using windows 7. i have installed everything but in uninstall and remove tab i cant see sony adb
This may sound silly but two things,
have you tried a different usb port
and is the sdcard mounted in cwm.
I have to make sure the sdcard is mounted before i can connect mine.
Do a hard reset hold power and up till the phone vibrates 3 times then try to connect to flashtool by holding power and volume down.

[Q] Bricked my HTC One X+

The titel says it all , and I need some help. I can still go in recovery but adb won't recongize my HTC, but I can still find it in fastboot. I formatted the sdcard, so I have nothing on there. Help would be much appreciated.

Oh, trust me that's not your phone being bricked. You guys seriously need to know the correct vocabulary.
Bricking the phone: The phone's only use is to use it as a literal brick. It does not turn on, does not recover, does not charge, does not do anything and it can never be restored.
HOX+ can NOT be bricked unless you are S-Off'ed. Now that we got that out of the way,
you seem to understand that ADB is the solution here, that you need to sideload a rom, the question that you have is the adb does not recognize your phone, so follow these steps:
-Connect the phone using a different usb port, (basically thats the easiest thing), if its 2.0 then try 3.0 and vice versa.
-Restart your computer
-Restart your phone
-If you are on windows Vista and later, open start menu search for "cmd" then right click and run it as administrator, then you need to cd to your adb directory.
Code:
cd C:\Android\sdk\platform-tools
for example. then try adb devices.
Anyway hope you get it to work and have fun

The only thing I can do is use fastboot , thx for noticing that I know I need adb sideload If I look in devices on my PC I can see 'ONE' with a yellow triangle next to it ( so this means drivers) I downloaded my HTC drivers and I right clicked on the device and then update from PC , I go to the folder where I installed it and click on search and it says it can't find a driver for this device.
I also tried 4 different USB ports both 2.0 or 3.0 , no result. I also tried to install TWRP instead of cmw but on TWRP my touchscreen doesn't work while on cmw it does. So i went back and flashed my recovery to cmw again ( I tried version 2.6 - 2.7.0.1 , no result )
So my problem right now can be solved once my device can be recognized by my PC. (Have HTC maneger installed , also downloaded drivers formy phone , got fastboot and adb on my PC )
For anyone who knows thanks

Hmmm. I would say in the device manager right click on the one and uninstall. Then in fastboot mode unplug and replug the device, let it install fastboot again and then try if adb can read it now.

This has happened to my phone twice... fixed it the first time by using USB deview to remove all Android/HTC drivers, then reinstalled them with the HTC Sync installer. Couldn't get that to fix it last time though, so I tried another computer and it worked just fine. So my advice would be to find another computer and try it.

I'm trying to connect my Samsung GS3 to my computer to use with the Android SDK Manager and the ADB console, but when I connect it to my computer it recognizes it as a Camera and ADB doesn't recognize it either, how do I fix this?

Since you're already looking in the right place, consider installing a custom recovery (such as philz) with odin and then flash the zip.
Thanks for the help. I was finally able to get my computer to recognize the GS3 (Installed Samsung USB Drivers from their website instead of Kies). But now after it recognizes that I have new hardware installed, when I try to use the Wizard to automatically install the drivers I get the error: "The required section was not found in the inf", did some searching and realized that this is due to not having the wpdmtp.inf file on your computer. I've checked and it is indeed missing, does anyone now of a way to install this file?
I'm still locked out of my phone. And I don't have an SD Card to install recovery and flash the zip as dxppxd suggested.

Take another shot by booting into a custom recovery, most give you adb access while in recovery.
If the phone is locked with usb debugging disabled you won't be able to get adb access.

PLS HELP! Cant get ADB Developer mode after flash. SGP312 stock FTF lollipop help

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

installing twrp from custom rom?

Hi,
I was able to install custom rom on my v300s
but found out that twrp wasn't installed.
I used my computer adb to open twrp and installed custom rom
Then i found our something was wrong, any way to install twrp from now on?
i tried to open twrp with adb again,
when i use adb devices I was able to find lge~~~ on there.
but when i try fastboot boot twrp, it shows awaiting for devices then nothing happen
(I set my phone as ptp mode then usb debugging was on.
on my laptop the phone was resister as portable device and using MTP usb driver, wasn't able to change it to adb driver)
then i tried to boot my v30 as bootloader but pressing volume down key didn't work.
any way to install twrp from this state?
sorry for my bad English
I think you need to ensure you have the correct drivers installed. Even when they are, you need to also check in Device Manager that the correct driver is used when the phone is connected. It also sounds like you don't have USB debugging enabled.

Ah the usb debugging was enabled.
I found something called qfil from qualcom and was able to reinstall my bootloader img file with it.
then i was able to connect my device as ADB devices
Thanks btw
