Hi there, I am from Thailand and I have problem with my A500. That i cannot access to the recovery mode and it shows picture of Android with this "!" symbol. The main problem is that i cannot update my firmware over the OTA when it completed download firmware and i installed it and then it appeared this "Update is invalid and has been canceled". So please help me to fix this problem, i really want to use 3.1!!!
Known issue. Acer have reportedly now pulled the 3.1 update whilst they fix the problem, and will re-issue it "tomorrow".
Otherwise, so far, the only known fix is to keep trying until it works.
Thank you for your reply FloatingFatMan. How about the issue that it cannot access to the "recovery mode", i have tried to update firmware myself and i stuck with this problem. Do you have any ideas for that???

First Ensure that your cell phone is rooted. after that...
On the same window option in System Settings - Find an option called "Root Access" and select "Apps and ADB" option.
I hope its help you
also check for developer->usb debugging notify...

I was having the same problem. I also had a box that said 'USB debugging notify' checked and didn't notice the device asking for permission to run adb right after I did the kill-server and start-server. As soon as I hit 'ok' the unauthorized problem went away.
Thanks to all on the thread.
I'm having the same problem, but a bit worst.
I accidentally erased my OS, so how can I solve that issue without an OS?
problem
I am having a similar problem as well. My old Samsung Galaxy S is stuck on bootloop. Home button is dead so I cannot acces download mode/recovery mode manually and in adb device is unfortunately unauthorized
Any way to go around this ?
unauthorized device, unable to adb anything
[email protected]:~$ adb reboot bootloader
error: device unauthorized. Please check the confirmation dialog on your device.
[email protected]:~$
[email protected]:~$ adb devices
List of devices attached
FA2BDS501095 unauthorized
With the phone connected via usb I went to Dev. Options, unchecked USB Debugging then rechecked it, instantly the confirmation dialog box came up regarding the RSA Key for my laptop. Check the box so it remembers your computer and hit save.
Same Problem! Phone stuck on Samsung logo
So guys,
I am stuck with this really bad problem : http://forum.xda-developers.com/galaxy-s3/help/nand-write-start-completewrite-t1846867/page4
and essentially my phone is unable to start up and gets stuck at the Samsung Logo.
So I am faced with the same error message of phone being detected by adb but unauthorized. Is there any way to access the root of the device overriding the authorization?
I had done adb before so it has to be checked within the settings.
Thanks a lot! Any help is appreciated!
are that problem was solved?
how?
What do you do if the RSA key dialog never comes up?
I have root, I have usb debugging enabled.
I've tried revoking authorizations.
I've tried adb kill-server followed by adb start-server
I've tried changing from MTP to MSC (those are the only two options I have)
I've tried on both an Xperia Z2 and an Xperia Z3 Tablet compact.
Both have the same problem.
No RSA key dialoge either
I have seen some RSA key apps but they are for creating keys. How can I get the dialoge to come up. I have a HTC One M8 831c ROOTED twrp recovery BadSeeds Stock Rooted ROM SuperSU PRO updated. Its on a Harman Kardon Edition which seems to be a little off from the other versions.

I have the same exact problem as you. Have you found a solution?
same problem
I have root
have deleted critical system files via titanium backup
i have USB debugging enabled
have revoked authorizations
i have systemui error which loops every time I boot
no home button functionality
no actual phone application any longer
no drop-down notification available, however banner notifications do present themselves only to disappear out of reach above the screen edge.
I have done everything the previous poster mentioned, and my problem is virtually identical to theirs.
Due to these particular circumstances, I am unable to receive the RSA prompt menu and authorize ADB.
I have root access but cannot enter ADB into root mode due to unauthorized device errors.
i am unable to do anything with shell functions as well
my phone is practically disabled at this point, to do anything useful is a daunting task of escaping and passing by the looping systemui error in order to slip into subsequent menus/functions.
The only solution I have found is to rebuild the boot.img file such that it excludes the RSA protocol or over-rides it.
factory restore does not remount vendor partition files no luck restoring from SD or cache.
I am sure I could rebuild the file but I would be pushing my boundaries, something I don't have particular time for at this moment. Being too busy with academics that currently dont encompass coding, I have no time to study on this one...
I will be happy to do my due diligence whatever the case may be, however...I need some answers. My phone is out of commission.
Same problem, did u get the solution?

I used OTG instead of internal storage and it works.

Your phone might be bricked. Did you recently try to root it?
bit late to the party, but this worked for me
I had RSA ADB fingerprint issues, worked for ages then stopped working, went through every forum post and nothing worked, then found this post.... stackoverflow.com/questions/31638582/android-adb-devices-unauthorized[/url]
opening a cmd prompt in this location C:\Users\<your user name>\AppData\Local\Android\sdk\platform-tools and running adb from here and it worked straight from the off.
i've spent 2 nights working on this, so if it helps anyone
my screen broke and picture is completely ****ed and useless.
is it possible to enable USB debugging without using the touch screen? i want to mirror the phone to a laptop and pull my work hour sheet
hy guys

thanks in advance
Hello everyone!
A friend of mine's phone got a system update, but something went wrong and now when the phone starts, it tries to install the update and then boots into recovery mode. I don't want to try and do a factory reset yet, because she had some important notes on SMemo which I want to retrieve with ADB. Problem is that I can't get ADB to see the phone. Can you help me out?
Thanks in advance!
Hi everyone,
I got an issue with my xiaomi redmi 4 prime/pro, I tried this morning to install the havoc rom and I got an issue with it. Then I reinstall an official rom from the xiaomi eu website and from there, it is a big mess.
Now, my phone won't launch at all. The best I can do is restart in fastboot mode and that's it. I can't even start the recovery mode.
When I try to play with adb on fastboot I can't do anything, I always have this message :
error: device unauthorized.
This adb server's $ADB_VENDOR_KEYS is not set
Try 'adb kill-server' if that seems wrong.
Otherwise check for a confirmation dialog on your device.
So I don't know what to do from this point. I spend hour on google to find a solution but I'm stuck with this error.
