[Q] Inc not recognized by ADB on Mac

Hey all,
My Incredible won't be recognized by ADB on my Mac through the terminal. I type in "adb devices" and it returns "List of connected devices" but doesn't actually list anything. If I try something like "adb shell" it says "error: no devices connected". What could the issue be?? I have a PC as well and ADB works fine on the PC.
If it helps at all the phone is recognized through fastboot on my Mac but I can't perform any operations... I tried to flash a new recovery through fastboot and when I tried to do "fastboot erase recovery" it returned something like "erase recovery failed status malformed"...
Thanks!

debug turned on? Thought that it needed to be adb

Yeah debug is on.... also in case it didn't go without saying I'm rooted.
Hope someone can help with this!

Thanks for the advice, but I had already followed those directions when installing the SDK. As I said, the phone is recognized just fine on a Windows machine so I can only assume it's some setting that's perhaps incorrect on my Mac? Maybe in System Prefs?
I dunno. It isn't the biggest deal but it'd be nice to be able to use the ADB on my Mac without needing to boot up the PC. Thanks!

Are you positive your path is correct..... and if it is check and make sure there are no spaces or weird characters....

was it working before and it stopped working? I noticed that my Mac doesn't recognized the phone every once in a while with CM7 and the Incredikernel. I have to unplug it and plug it back in couple times to get it to register.

I'm pretty sure it's correct because the Terminal recognizes the "adb" commands as valid. For example, I can run "adb shell" and it returns "error:device not found". So I don't think that's the issue...

The thing is, the computer recognizes the phone just fine. I can plug it in and select "disk drive" and both the phone and SD card mount without an problem. But when I try to run adb commands that's when it doesn't seem to see it for some reason.... I really don't get why this could be, when without changing a single setting on the phone it works fine on a PC. I'm probably missing something obvious, but I don't know what that might be.....

forgive me if im asking a dumb question im just trying to help you narrow down your problem,,,,,, did you check and make sure usb debugging is checked? and if you type adb devices what does it say? ive noticed on the newer sdk that i installed they moved adb to platform tools and out of tools so you might check those things

Yeah, USB debugging is checked... when I type "adb devices" I get "List of devices attached" and it doesn't actually list anything. And yeah, the Terminal is definitely pointing to the right folder, I don't think I'd be getting any sort of response if it was pointing towards the wrong place, right?
ADB definitely works. It just doesn't like my phone for some reason

Well it definitely works on OS X 10.6 that's what my laptop uses. Have you tried parallels or bootcamping into a version of Windows? My work iMac is a piece of dirt and does not like adb thru mac os x but works fine with win xp on parallels.

Yeah, I'm running 10.6 on my laptop as well... right now for when I want to use ADB I've just been running XP on my bootcamp partition, which works fine. It's not the worst solution in the world, but I'd prefer being able to do it on the Mac side of things, which is where I spend far more time.
This is very mysterious....

Fastboot Not Working and CWM Not Installing

Hello, I'm having some problems with my HTC One X.
When trying to send commands to the phone while it is in fastboot, cmd says "waiting for device" and doesn't change.
My bootloader is unlocked and CWM Recovery is installed although when I try and install one of the 4 ROM's I have on my phones internal storage the installer looks like it's working until it gets to around 20% and then says it is complete. When the device restarts it gets stuck on the "HTC quietly brilliant" screen. I am however still able to mount the phone and put files onto it through CWM. I have tried to use RUU and this just gives an error about USB not connected.
If you think you can help, thank you and if you need to know anything else I will try and give you as much information as I can.
Thanks,
Andy

Here's a checklist for you:
Phone in fastboot mode
Correct drivers installed
ADB/fasboot up to date
What does 'fastboot devices' return?

Yeah, it was all working earlier today but it just seemed to stop. fastboot devices returns
"c:\Fastboot>fastboot devices
c\:Fastboot>"

What OS is your computer running? Does it say FASTBOOT USB on phone display?

I have a macbook pro as my main computer but all things to do with rooting I do on a windows desktop.
This display says fastboot usb but all fastboot commands do nothing and it still doesn't show up in fastboot devices.

Reboot pc and phone if you haven't already.
You could try it with your mac, there's plenty of guides out there on how to setup.
Make sure to use sudo!!

Tried it on mac like you suggested, still no devices listed. And installations still only get to around 20%.
Do you think it's bricked?

[Q] Stuck in boot loop

Hi - I know this problem has probably been covered many times, so forgive me :angel: if I'm "boiling my cabbages twice", as my mum always says.
About a year or so ago I installed Android Revolution on my HTC One X - it took me a while to figure out what to do, and how to do it, but I eventually got there and it worked fine Anyway, i was reading an article the other day about how good the Cyanogen ROM was so decided to give it ago. Silly me
After many hours of hair pulling and cursing I've hit a brick wall, and could really do with some simple advice in plain English. I think I may have well and truly screwed up. I downloaded the Cyanogen ROM and flashed it, but kept getting the 'boot loop' logo. I still had a recovery file on my phone from when I installed Android Revolution, and this allowed me to reboot into Jelly Bean 4.1.1 (I think). Now, somehow, that file has gone and all I can do now is get the Cyanogen boot loop, or the Team Win Recovery Project menu. I can boot into the HTC menu (whatever it's called) by pressing the power and volume down button, but that's about it. My partner tells me "that'll teach you for messing"
Please, is there somebody out there that could possibly talk me through a simple, idiots guide for idiots method of getting my phone working again? :fingers-crossed:
Many, many thanks in advance
:crying:

Thanks for replying - that's one of my problems: my PC won't recognise the phone when it's connected. If I boot into the Team Win Recovery Project I can mount the USB storage and view files and transfer them from PC to phone and vice-versa, but I can't start the command prompt. It seems the boot menu on the HTC doesn't recognise the internal storage/USB

When I boot my phone into the 'Fastboot' menu and select Hboot it comes up with 'Failed to open master USB mode' and then goes back to the previous screen. Doing this it does not show up on 'My Computer' on my Laptop.
By rebooting into TWRP I can see the phone as a 'Removable disk' on my laptop, and when I right click on the drive I can see the folders .android_secure, data, showme, nero_sync, Albums, Android, dcim, Download, LOST.DIR, mobile, My Documents, Notifications, Pictures, ROM's (which I created), TWRP and a file called 'nmdsdcid.
If I shift+right click here for the CMD prompt, E:\>fastboot getvar all it returns with "'fastboot' is not recognised as an internal or external command, operable program or batch file"

Now do exactly what I write you. Disconect the phone from USB. Start the phone in bootloader and with the buttons volume up and down navigate to fastboot and press POWER button onse. you will see your phon will change HBOOT with FASTBOOT after this connect the phone to the computer with USB cable and you will see FASTBOOT USB after this run the command. When you go in bootloader your phone must NOT TO BE CONNECTED to the computer

Thanks for your reply - I have done exactly what you said, but the phone isn't recognised in 'My Computer' but I can see it under device manager. When I connect it with the USB cables the laptop makes a noise as if it is identifying it. On the phone it says what I said earlier about failing to open master USB, and then goes back to the Hboot menu and the laptop beeps to say the phone has been disconnected

Same Problem
I have the same problem after updating from CM 10.1 to 10.2 from settings. I had this problem earlier and fastboot solved it, but this time around I can't boot into recovery by pressing the power and volume down button, it just keeps on restarting. I think there's a chance there's something wrong with the volume down button. Help please. :'(
Edit: So I pressed REALLY hard on the key and it worked. Flashed the boot.img by putting it into the zip folder BootUpdate_by_hestheone64. Still stuck in the loop. :/

[Q] cant enable usb debugging, fastboot doesnt work

I have a Nexus 7 2013 that wont boot. USB Debugging was not enabled. At this point, I am just trying to wipe the machine with a stock image, but I am having trouble.
I have installed the sdk and drivers (so many drivers!)
Recovery mode fastboot does not recognize the device.
ADB recognizes the Nexus, but I cant seem to get it to do anything with it.
e: failed to mount anything.
I have read through so many forum threads that I'm just overwhelmed, and they all seem to require the machine being in USB debugging mode before any changes can be made.
Please help or tell me what pertinent information I have omitted.
Thank you

I think USB debugging only matters in ADB, which is when the device is actually booted into Android OS. You probably want fastboot, which is a different "application" and set of commands in a command prompt.
Code:
fastboot devices
Does that give you anything when the tablet is in fastboot mode? It should list the serial number of the device, similar to "adb devices" does. If not, it could be drivers, or another issue with the device.
Have you tried unlocking the bootloader? This will induce a factory reset of the current firmware version, which may allow you at least boot normally and take any available OTA updates.

Hello,
fastboot devices lists nothing, while adb does show the serial number.
I have used so many tutorials and a couple of toolkits that now I have no idea what is happening with my drivers.
Unlocking the bootloader to force a factory reset sounds amazing, but all the information I can find says I need to have USB debugging enabled to do so. I can not boot into the system to enable it.
Is there a way to force a reset without USB debugging?
Thank you

Usb debugging is irrelevant. Forget about it, it's only used when the system is booted.
You need to get fastboot devices to recognize the tablet.
Uninstall any and all toolkits and drivers. Redownload the sdk. Boot to the bootloader and plug it in, the drivers should install automatically. If not install the google usb drivers from the sdk manager in the sdk.
Try fastboot devices again. If it doesn't work try a different usb cord/port/computer.
You are in the bootloader when running this command right? Not the recovery? I think with the tablet off it's volume down and power. The screen that says start in big green letters at the top and has device info in the bottom left is what you want.
Edit: Did you boot to recovery and select the options to wipe data and cache? Sometimes thats all thats needed.

Also booting to recovery and performing a factory reset may be sufficient.
ADB will indeed function in recovery. I don't think you have to enable USB debugging to get this to work though.

Are you typing fastboot devices while booted in recovery? Typing fastboot devices while in recovery or booted into Android will do nothing.

hello, thank you for your advice. I now get the nexus seen by fastboot (and win 7) but have hit a wall. The last time I had my computer and the nexus together was weeks ago, when I my computer BSOD during what I thought was a simple flashing of the the stock image, but turned out to be hours of the nexus saying it was erasing personal data ... and then crash. I have replaced and added fans so my cpu wont overheat again, so please offer ideas why "fastboot flashall" or "fastboot flash image-razor-kot49h" wont work.
I appreciate all responses, and believe the answer is either very simple or a catastrophic hardware failure. I base this belief on what is left in my head after smashing it into the wall so many times over the last month when my wife asks me, "have you fixed my nexus yet, or do I need to figure out a way to buy a new one next month?"
I am stuck at unlocking the bootloader. I have highlighted "yes" on the nexus and pressed power and my command window says "erasing user data." It has said this for the last 18 hours. This is the second computer I have tried this on, using 3 different usb cables. What am I missing?

This may help...it may not. But I was having issues getting my bootloader unlocked also when I started on mine. My remedy was to
1 plug in the nexus into the usb
2 I run Linux so it gives me choices on what to do with newly plugged in usb device. I noticed two identical choices to mount device. Choosing one just mounted the camera for some strange reason. I closed that window, then chose the other choice to mount device, the window opened and my full internals were there in the window
3 from a terminal I just wrote a prompt: fastboot oem unlock
and for some reason, it unlocked.
To sum it up I'm convinced it has something to do with how the device gets mounted. At least on mine anyway.
As for activating developer from a terminal I read it could be done but never tried it myself, if you want here's the link for the info, read the second answer down.

After re..re, rereading your post, and responces. Have you tried the old fashioned way
Hold down the (down volume) button at the same time the (power) key.."Together" If you get anything that pops on your screen let go of the keys, one tap at a time tap the volume up or down key ONLY, until it says (START), its in green type. if you get there you should be ok, to move along

[Q] HTC M8 not being seen in adb

OK using a windows 8.1 Pro laptop, ADB installed properly with HTC Sync Manager, both Windows, HTC Sync Manager and the Device Manager in the Control Panel can see my phone. I tick on USB debugging and then press revoke USB debugging authorizations. Unplug my phone and plug it back in. I'm using the original USB cable from HTC. Everything pops up and shows like it's connected, except when I type in
Code:
adb devices
in the command prompt, then it just comes up blank. I've attached screen shots so you guys can see what I am talking about. If you have any ideas it would be much appreciated. I've attached some photos just to show that I've dotted all my i's and crossed all my t's as far as I can see. I also want to point out this is the second computer I've tried this on.

Yeah that didn't work, I even tried installing the USB Driver manually and that didn't work either. Still comes up as not connected, it's super frustrating.

Not sure if this helps but for some reason my Android Phone isn't showing up under Android phone in my Device Manager, it's showing up as Portable Devices. I don't know if this is an issue or not, anyone care to give an opinion?

OK using a windows 8.1 Pro laptop, ADB installed properly with HTC Sync Manager, both Windows, HTC Sync Manager and the Device Manager in the Control Panel can see my phone. I tick on USB debugging and then press revoke USB debugging authorizations. Unplug my phone and plug it back in. I'm using the original USB cable from HTC. Everything pops up and shows like it's connected, except when I type in
Code:
adb devices
in the command prompt, then it just comes up blank. I've attached screen shots so you guys can see what I am talking about. If you have any ideas it would be much appreciated. I've attached some photos just to show that I've dotted all my i's and crossed all my t's as far as I can see. I also want to point out this is the second computer I've tried this on.

That's normal as the phone is using MTP, the Android Phone entry only appears once the drivers are installed. It's definitely a driver issue but as to what I can't say as I have no issues on my 8.1 Pro laptop

I think I figured something out, just flash CM 12 - (God it's amazing. ) and now I can see my phone on ADB, so whatever ****ery was going on I am blaming it on HTC stock rom.

is cm12 worth the hassle?

Sorry for the necrobump, but I ran across this thread while researching the same issue on my M8 and wanted to save anyone else the trouble if they also stumbled across this same issue.
Though the solution discussed would likely work, if you don't want to hassle with a new ROM, it is possible to fix it on your existing ROM provided you have root.
[SOLVED] ADB 'unauthorized', no RSA prompt, and no 'Revoke USB debugging' option

Thanks for this guide you put up. Interesting that there was no option for you to revoke USB authorization. My device is S-ON and have been using Viper for a while with the option available. Same for HTC stock. Good for you getting that fixed. Had a similar issue on a different device months ago.
