hi everyone, i'm trying to install CM9 on my LT15i, i've tried using the CM wiki instructions and both the following guides...
androidauthority.com/xperia-arc-lt15i-root-android-4-0-ics-80265/
and
androidforums.com/rezound-all-things-root/506466-scottys-noob-friendly-root-guide-start-finish.html
the phone is already fully unlocked and has CM 7.2.0 anzu installed. i've tried simply using the clockwork recovery mod bootloader to wipe the phone and install CM 9.0.0, but on reboot the phone gets past the boot logo then just shows a black screen, so i assumed i needed to flash an appropriate ROM for CM9; this is where my problem begins.
every forum i've read about this process says i must enable usb debugging (done) and "disable fastboot" under settings>power, i do not have a "power" option in my settings and cannot find anything related to fastboot on the phone; although i'm not sure this is the problem. when android is running normally and i attempt to list devices with adb.exe on windows, it successfully returns the phone's serial number. when i shut the phone down, hold the menu button and plug in the usb cable, fastboot mode appears to work correctly as the LED comes on blue and "android adb device" appears in the windows device manager (i've tried installing the arc usb/adb drivers from various sources, they all seem to work correctly). but when i attempt to list devices after restarting in fastboot mode, adb.exe says it cannot find any device. fastboot.exe has not communicated with the device whatsoever, but i assumed i might need to get the adb.exe usb daemon/server running correctly first for this to work.
i did this process once already when i installed CM7, it was successful the first time and everything went smoothly. from what i recall i just did exactly as described above and fastboot.exe was able to find the device no problem. but that was a number of months ago, hopefully i'm just missing some obvious step.
cheers

There is no such thing. And USB debugging is only required if you want to root stock ROM, every other action can be done without it.

Drivers, drivers, drivers.
If your phone is in fastboot mode, make sure drivers are installed. Proper drivers.
You do not need ADB server for installing a kernel.
Just open up Command Prompt and install the kernel with command
Code:
fastboot flash boot boot.img
.
Assuming boot.img is in the same folder as fastboot.exe.

thanks for the reply someguyfromhell. i've tried every "android adb interface" driver under the sun for the S1 fast boot device that appears in the windows device manager when i put the phone in fastboot. when i try to send any command with fastboot.exe it just hangs at "waiting for device", i've fiddled with this stuff every which way and just cannot get fastboot.exe to see the phone. i've tried switching up the usb ports on this computer, but haven't had the opportunity to try a second computer. you've let me know i'm going in the right direction at least, if i have the same results on a second machine i'll pursue the issue further.
thanks again

You need to unlock bootloader, if you want to install CM ROM. Arc S can only have bootloader unlocked via official method, there you can also download the correct driver which you need.

So I have had my Galaxy Nexus since the day it came out, I rooted it before I even activated it.
Like many, I have used all sorts of different ROMs over the year period.
I have never had any problems with adb or anything. I have pushed and pulled files and all of that numerous times.
Until yesterday, I finally upgraded my recovery from an really old (first touch based recovery) to the newest TWRP. It worked fine. I put my phone into fastboot mode, and was able to flash the new recovery through the command prompt (adb/fastboot) on my PC. Then I switched to a new 4.2 rom (Paranoid android 2.99)
So today, I wanted to try some editing on some system files, so I went to go pull some files off of the phone (using adb of course), but now it just tells me that my device is offline.
I tried
"adb kill-server"
"adb start-server"
"adb devices"
It lists my device number, but just says "offline"
I tried to update everything. (Samsung main Drivers - Google's USB SDK drivers - and the newest version of android-sdk)
Also made sure that my USB-debugging was set on my phone.
Even if I put my phone in fastboot mode, it doesn't recognize it anymore. Which is weird because just last night it worked perfectly fine when I upgraded my recovery. I am frustrated to no end...... Can anyone else tell me what I might be missing here?
Nobody?

only thing i can think of right now, before suggesting omap flash or odin, would be try a different usb port, another computer, another OS!
try installing the latest CWM recovery and see if it helps.

Try going to settings and look for something related to Root Access and it would have three options:
1. Apps only
2. ADB only
3. Apps & ADB
Choose the 3rd.
You might have to hunt the exact location under Settings where this option will be available as I don't remember them exactly.
Hit Thanks, if this helps...
I looked, but I don't see those settings anywhere.
I tried multiple USB port's. Switching from my USB 3.0 ports to my 2.0 ports. nothing. I can still access the phone storage. So I know it is still connecting to the PC. I could try to boot up linux, but I don't have any of the driver's and sdk tools on my linux drive, and from what I heard it was hard to get it all running in linux.
I guess I could try to change recoveries from TWRP to the newest CWMR,
but last time I turned my phone off, put it in fastboot mode, adb didn't recognize it. So im assuming it won't let me flash anything. Unless fastboot sees it but adb doesn't?
I mean my phone is working perfectly fine, running the new recovery and rom. But I have to be able to connect to adb. Not only for modding but in case of an emergency where I would need to flash.

I understand your situation... Since you were not able to locate the option suggested, a little Googling answered it's location, check for same and confirm:
Settings > developer options > root access > apps and adb
This should hopefully help resolve the issue.

hi. i try all this ways. i know that my usb debuging have problem, in development option i'll checked this, and it says enable. but infact it's not enable and still i got device offline error.
also i use z4root app and when i touch on root, it says that rooting need usb debuging enable (please enable it)!!
then move me to development setting to enable that, but this was checked and enable.
is any way that we make device online from my phone? for example using terminal emulator to turn on usb debuging or turn it off. this way is only my way! any one know some trying this?
i also use usb debugger app, but it move me in settings too! LOL
i need enable my device to root that.
thanks every one
I know this is an old topic, but if somebody else googles it, I had that offline issue, the solution was to upgrade adb : http://stackoverflow.com/questions/10680417/error-device-offline
You simply need to upgrade to the latest version of adb. Went thru this a few weeks ago.
Windows 7 x64
Galaxy Nexus i515, BROKEN SCREEN, USB DEBUGGING WAS NOT TURNED ON. The phone is completely stock I just turned it on and used it until I broke my screen. Screen lock is on.
I have been trying to access my phone, using Fastboot, to wipe it before I send it in for warranty. I can not seem to do this at all. It seems that I can not install the drivers because I have not enabled USB debugging. Is this true? I have been following this guide : http://www.teamandroid.com/2012/07/30/how-to-set-up-adb-fastboot-with-android-sdk/2/ When i go to manually install the drivers, from SDK, I get, "The folder you specified does not contain a compatible software driver for your device. If the folder contains a driver, make sure that it is designed to work with Windows for x6-based systems." I then tried the driver from Samsung and got the same response.
So then I hold VOL+ _ VOL- and Power and tried to install the drivers for Fastboot with the same outcome as above. Also when I boot in Fastboot mode the drivers that are installed make my phone a modem. The driver is called, "SAMSUNG Mobile USB Modem." I can not get this to change.
So to summarize I can not get the ADB Drivers to install, because I do not have USB Debugging enabled, that in return will not allow me to install Fastboot Drivers because when I plug the phone in the computer sees it as a Modem.
Any suggestions? I am just trying to erase the info on my phone I have given up all hope of recovering any data.
Thanks,

I meant a screen pattern lock. When you wake up the screen you have to connect the dots in a certain pattern before your screen unlocks and you can use the phone.
As far as, USB debugging drivers/interface having nothing to do with fastboot drivers/interface, then what am I doing wrong? I can not get my computer to see my phone as an android device.

Uninstall all drivers, reboot pc.
Assuming device is off: press power+vol up+vol down, until you feel the vibration. Wait 2 secs or so. Device will be in fastboot mode.
Read this thread, i say again, READ this thread, obviously start with the first post! - http://forum.xda-developers.com/showthread.php?t=1812959
Thanks for the link. I read it and followed instructions for installing the drivers. Here is what I did:
1.Uninstalled all drivers
2.Rebooted my PC
3.Downloaded these Drivers, as suggested: http://forum.xda-developers.com/showthread.php?t=1379875
4.Followed these instructions, on how to install the driver without windows trying to find one automatically: http://forum.xda-developers.com/showpost.php?p=29044502&postcount=735
Everything seemed to go well under the Device Manager, when I plug my phone in in fastboot mode, it shows Android Phone -> Samsung Android Interface. This is way better than what I had before, when it was showing up as a Modem. Now when I try to use fastboot.exe and I type "fastboot devices" nothing shows up. I reset the computer and replugged in my device, in fastboot, and the same thing nothing shows up in fastboot.
Thanks for you help.
Did you miss the part about having to feed windows the same driver again, when connecting the device for the first time, in FASTBOOT MODE?

Not sure if I understand what your asking.
I followed all of the steps here: http://forum.xda-developers.com/showpost.php?p=29044502&postcount=735 I connected the phone booted normally and let windows find a driver so that the driver reads Portable Devices -> Galaxy Nexus. Then I unplugged the Nexus and booted it in fastboot mode and plugged it in. Next I followed the directions to install the Universal_Naked_Driver, in fastboot mode. I can not install the driver for ADB because I can not enable USB Debugging with my broken screen.
Thanks Again.
Why is it so difficult for people to understand that USB debugging has nothing to do with anything outside the booted OS?

W8 a sec, do you even have your bootloader unlocked???
You said you're running stock, so that should have been my first question, because to unlock your bootloader through the usual way, you need to confirm a dialog on the device... which in your case, doesn't have a working screen.

pay attention to part 3)
3)
NOTE:
- The method described here can be used to install the "Samsung Galaxy Nexus ADB Interface" driver as well as the "Samsung Galaxy Nexus Bootloader Interface" driver.
- Differences between the two procedures. One is done with the phone booted up normally and "USB Debugging" is enabled, and the other is done when the phone is in fastboot. I will cover the "USB Debugging" part here.

then...
We will now install the two drivers that efrant talked about in his post.
A) (FOR ADB - WHEN RUNNING ANDROID OS):
Enable USB debugging on your device
- Goto Settings > Developer Options > Check "USB Debugging"
- Connect device, manually update driver to Naked driver by 1wayjohny, done. On 4.2 and above, you'll need to confirm that you accept the host's (your pc) RSA key.
B) (FOR FASTBOOT - WHEN RUNNING FASTBOOT MODE)
boot into fastboot mode - power off phone and hold vol up + vol down + power
Click to expand...
Click to collapse
Both for A) and B), you need to do the "Update drivers manually" part!
Right now, your only option is B), that is to use fastboot to either:
- Flash stock images.
- To get your data back, boot a custom recovery (which won't require the RSA key confirmation for ADB) from fastboot, then use ADB to pull your /sdcard/ or whatever.

I am learning this ^. I am having trouble getting my computer to see my phone, in fastboot mode. All of the instructions that I have read start with installing drivers for ADB, which requires the phone to be USB debugging mode, and then the drivers for fastboot. So I thought my trouble was, since I can not install the drivers for ADB, and that I was having trouble with all of my drivers, that it was probably the fact that my phone can not be put into USB debugging mode. I now realize that USB debugging has nothing to do with fastboot, as fastboot is before the OS is booted. I am still just having trouble with my fastboot driver and seeing my phone with fastboot.exe.

No. Fastboot should be able to see your device if the proper drivers are installed. Fastboot is REQUIRED to unlock the bootloader

If you used odin to flash something, that will unlock the bootloader. Flashing a section of edited param using OMAP flash will also unlock the bootloader.

My galaxy C5 is also not recognized as a bootloader interface while in fastboot mode, after installing all the drivers correctly. Samsung usb driver v1.5.63.0 makes the changes i think, and it makes it as a modem instead of bootloader. maybe the solution is i have to manually update the driver of that modem into bootloader, right click on the modem in device manager and change it's driver into bootloader of your phone, maybe it works. I will try it this way.
Let me know if this solution has worked for someone.

Howdy,
I'm trying to get my phone unlocked and rooted. As the first step, of course, I'm trying to get the Google USB drivers to install, but I simply can't. I feel like I'm the only person having this issue, though because I cannot find a solution... The steps I'm following:
Downloaded the latest driver zip from Google
Open Device Manager
Expand Portable Devices
Right-click on the Phone entry (notice, that's the entry, "Phone". Not Razer.)
Choose Update Drivers
Browse my way to the drivers folder and click Next.
Windows then returns immediately "The best drivers for your device are already installed", and shows that it's an MTP USB Device.
I noticed that under USB devices, there's an ADB Interface device listed, and I get the same results when I try to update that, too (excepting it says it's an "ADB Interface" device, of course). I have tried uninstalling both devices to get the drivers to install, but no such. I've rebooted both phone and computer as well.
On the phone, USB Debugging is turned on, and USB mode is set to MTP file transfer.
Please help!
Figured it out...

In case anyone else is seeing the same issues, I wanted to put my resolution up: I'd been trying to install the drivers with the Razer booted. On a whim, I rebooted it into Download Mode using "adb reboot bootloader". Once there, I had an Android Device listed in Device Manager. I ran the driver update wizard, and installed the "USB ADB Interface" option from the choices presented. I was then able to run the OEM unlock command and received the confirmation prompt on the Razer. Yay!
Now, since it's been so long, I've got to re-back-up everything so I can actually do this thing. LOL
Here's the PDF from Razer's how to install a factory image over PC guide. It explains how to do it all

Hello, my Oneplus 3 finally met its maker when it slid off my knee as I was doing a poo. This phone had served me well for a long time and was used for the last year without a functioning power button.
Today I was trying to extract my data from the phone using adb. However, I have a few issues.
The screen is fully black and shattered and digitizer appears to also be broken.
I can use the fingerprint sensor, but not much else. If I try to apply pressure to the screen, the device disconnects from the computer then reconnects.
My phone will not show in 'My PC' and just shows as 'android' under 'USB devices' in Device Manager, I try to update the driver through this and I am just assigning it to be an 'ADB device' or 'Oneplus Android ADB Interface' which does not help.
I have downloaded the Oneplus USB drivers and installed them which did not help or allow me to select those as driver updates in 'device manager'. Even after turning off signed driver checks in boot options.
I believe I have USB debugging on, as I turned it on not long ago due to the power button failing. But when I attempt to use ADB I either get 'unauthorised' or 'offline' beside my devices serial number.
I have tried unlocking my device with my fingerprint and it has the response vibration but does not allow me to access it.
Ideally I would like it to work with '[email protected]' and 'android control' but I would settle for just being able to pull everything off the device. I have been reading threads and trying fixes all day to no avail. Please help me.

If you had used adb before and the phone was recognised earlier, then there shouldn't be an issue. If not, then when issuing adb commands, there will be a popup on the phone asking you to enable authorisation and to make it permanent. In your current scenario, you will not be able to grant authorisation. Your drivers might be installed properly but because of this "authorisation" issue, the phone might not be recognised properly.
Search for methods to pull data from the phone. I had read about a couple of methods where you can mirror your screen on the PC which will solve the problem for you. Unfortunately I am not able to recollect where I read that.
EDIT: Enter fastboot mode on your phone and connect it to the PC. Then using 'fastboot boot twrp.img' you can boot into TWRP on the phone and access the files and copy them using adb commands. This requires the TWRP in the same folder as your adb tools or vice versa and renaming the file as TWRP. I don't know whether this also requires 'authorisation' but try it any way.
