Hello, everyone
I rooted my phone 2 weeks ago and 2 days ago I got an update notification which I did and then something occurred and the phone started to reboot itself.
I tried to recover from the backup that I did when I rooted the phone and now there is a new problem. When starts, a message "com.android.phone has stopped working" pops up and I can't use the phone.
I tried starting on Recovery Mode multiple times with no results, the phone just starts normally. I also tried to connect the phone to the PC (Running linux) but the command 'adb devices' shows nothing.
Any help is appreciated.
Thanks!
P.D: Srry for my bad English
Enable usb debugging on developer options and plug the phone to your pc and run the comand "adb reboot recovery" and it should reboot to recovery
Sorry for my english

Hi!
Developer Options were already enabled. But the the computer doesn't recognize the phone. When running 'adb reboot recovery' it says "error: no devices found" (on windows) and error: device'(null)' not found (on linux)

On windows, you have installed the drivers??? And if you want view the devices that are plugged run these "adb devices" if the problem continues, try with an different pc or port usb
You can't boot into recovery? but why?
When you select "Recovery" option in fastboot mode what does it shows?
Its kernel error I guess....vest option would be to flash recovery using flashify or ad again

I have 32GB WIFI, Nexus 9 bought from Amazon which unfortunately has got stuck in boot loop after updating to 5.0.2 (LRX22L) released on air . My device is locked and it doesn't give permission to use "fastboot oem unlock" command thus I can't flash factory image because it says device is locked. I've tried Factory reset from fastboot mode and also from Recovery menu (wipe cache partition and wipe data/factory reset) and it still has the problem. That's worthy to note that PC recognizes device with "fastboot devices" command but it doesn't recognize using command "adb devices".
my PC's OS is 64bit windows 8.1
Then I tried using "Apply update from ADB" in recovery menu and sideload which gave me E: footer is wrong and signature is unspecified but in this mode command window in platform-tools path recognizes device as "adb device" command used.
The other thing I tried was unlocking the device using adb shell (and so on) and it says :closed
I'd be grateful if you folks, helped me with your solutions.

You only have one solution: return it to Amazon for replacement.

You mean there is no other way for rooting or unlocking Nexus9 ? any program, application , command etc?

Correct. No way if your bootloader is locked.
Hi!
I have RN2 with MIUI 16.6.7.0 with root access.
ADB v1.0.32
Win 8.1
If I run "adb devices" when phone is running system, I get response "s/n device" as I should. But when I boot phone to recovery (MI-Recovery 2.0.1) I get "s/n unauthorized".
I have tried rebooting PC and phone, disabling and enabling USB debugging, deleting adbkey and adbkey.pub on PC (only instance was in users/user/.android/), revoking USB debugging authorizations, changing USB ports. Nothing.
The last thing I did:
1. reboot phone to system.
2. developer options > turn developer options on/off > turn debugging on/off <> Revoke USB Debugging Authorization
3. reconnect phone to PC
4. was asked: RSA key fingerprint + always allow from this computer > OK
5. run "adb devices" gives "s/n device"
6. disconnect phone
7. power off phone
8. phone to recovery
9. reconnect phone
10. run "adb devices" gives "s/n unautorized"
11. disconnect phone from USB
12. run "adb kill-server"
13. run "adb start-server"
14. reconnect phone
15. run "adb devices" gives "s/n unautorized"
I guess something is wrong with recovery mode on the device. Any ideas?
Thank you
MK
+ run "adb shell" gives " error: device unauthorized. This adbd's $ADB_VENDOR_KEYS is not set; try 'adb kill-server' if that seems wrong. Otherwise check for a confirmation dialog on your device."

"On the device, vendors public keys are installed at build time in /adb_keys. User-installed keys are stored in /data/misc/adb/adb_keys."
On my device user-installed keys are stored in /data/misc/adb/adb_keys. The only other instance of adb_keys is /bin/adb_keys. If it has any relevance.
You need to check in the device the popup, the device ask if you want authorize your computer for connection with adb, remember you need to enable adb debug first with push 7 times on miui version into about device.
In recovery adb isn't available you can enable only the adb transfer from the advance menu.

Hi!
Thanks a million for your reply. :good:
I did all that already in steps 2, 4 and 5 and it worked. My problem is adb in stock recovery mode.

Damn I have much to learn (hundreds of pages in a few days and I still dont know anything . So stock recovery doesn't come with ADB access and I am trying to do something that can not be done? ClockworkMod recovery for example should have ADB support if I understand correctly?
I also have that proble my device not connected to phone what I do tell me..

If problem is PC <> phone then install drivers for your phone on PC.
Or describe your problem better.

I'm trying to flash TWRP, i've got ADB and i've got the Universal ADB Drivers. The device is properly detected when in EUI and my Device ID is displayed correctly when I type 'adb devices', however when I reboot into fastboot and type 'fastboot devices', nothing is listed and cannot continue.
Which drivers do I use? What is it that I need to continue?
Thanks!
Edit: Nevermind, connected it into my linux machine and got it to work easier (lol winBLOWS amirite) and finally got it to recognize the device in fastboot mode. I kept rebooting and failing to get into TWRP. I found somewhere else that before doing 'fastboot reboot' that you should hold VOL UP so you can immediately boot into twrp and make it permanent, which ended up working for me. Freedom!

I believe you need to configure in the developers options that you don't want to have the recovery overwritten on reboot. What also seems to work is to boot into the TWRP from the command line via 'fastboot boot <recovery-file-name>'
I have the exact same problem. I have installed all drivers and adb, but as soon as i am into fastboot and my device doesnt show up in the command line. If i want to install the recovery the command line just says <waiting for device> and nothing happend.
I already enabled the "Enable AT Port" Settings (http://forum.le.com/in/index.php?threads/le-max-2-x820-qpst-not-working.14820/) but i think this is not permanent turned on on my phone, because i have to repeat this step after every reboot.
Anybody got some tips?
Edit: Also booting directly into TWRP doesnt work, 'fastboot boot <recovery-file-name>' just ends up in <waiting for device>..
If you're using Win 8 or Win 10 you should turn off the driver singing verification before installing usb drivers for device.
In your case one of the drivers was blocked from installing and the systom does not see the device after it switches in fastboot/recovery mode.

Thanks for this Hint! Didnt know this
Nevertheless, no improvement so far. I Unistalled every driver and installed them again, but the PC doesnt recognize the phone when its in fastboot mode

There is a chance, that your computer has installed the WRONG driver for the fastboot mode, so find any related to the phone entries in Device Manager when the phone is connected in fastboot mode, and if it is not "Android Phone/Android ADB Interface" -> remove them with remove driver checkbox checked. Optionally, if nothing changes -> try to manually pick the device driver to Android ADB Interface

I tried it now with the fifth computer and after a few strange error messages, it "succesfully" installed TWRP.
BUT: There is no TWRP installed on my phone. I followed every tip which i found how to exit the fastboot mode (pressing Vol+ & Power / Removing USB Cable / Tried TeamSpains Automatic Installer).
What is wrong with this phone ? - I think i will oben a new thread, thanks for your help!

Kampfgans: Klingt irgendwo zwischen lustig und richtig bedrohlich...
Lots of ROMs (including most CM variants) like to "automatically 'recover'" recoveries, that is they overwrite the recovery partition with a copy of the "original" every time you reboot.
I seem to remember that my first attempt to overwrite the stock recovery using "fastboot flash recovery <twrp-image-name>" also didn't succeed in making TWRP "stick".
Within the CM13 which I installed next (over the stock v15) there is a developer option to control that, but in this case I simply used a trick, which seems to bypass the recovery overwrite: I told the phone to boot the TWRP recovery over USB after flashing.
It went like this:
fastboot flash recovery <name-and-path-of-TWRP-recovery> //puts the TWRP image on the recovery partition
fastboot boot <name-and-path-of-TWRP-recovery> //bypasses the recovery overwrite logic of either the bootloader or whereever it hides
That booted TWRP over USB and allowed me to install CM13.
There I disabled recovery overwrite in the deveoper's options and I've never had issues with TWRP disappearing since.
Actually you should in theory be able to leave the stock recovery in place and still use TWRP by booting it over USB on the fastboot command line.
I install drivers and USB but when trying to go to fast boot I receive "waiting for device"
I'm running into issues with my Compact X. Current situation:
- Omni 8.1 rom installed, but doesn't boot. Stuck on Sony logo.
- TRWP 3.3
- Rooted
- When in fastboot mode (vol up + connect usb cable) the device manager shows: Android Device > Sony Fastboot Interface.
- Windows 10 running in "Test mode"
- adb & fastboot v1.4.3
ADB does not recognize my device when the device is in fastboot mode. When it's in recovery mode the command 'adb devices' shows me the device listed. I can then reboot in fastboot mode, but then the device isn't listed anymore. I'm not sure what happened because a couple of hours ago I installed TWRP using fastboot.
I'm trying to get this thing up and running again, but not being able to flash anything via fastboot complicates things. Any idea's what could be the culprit?
Download official Android drivers by Google and force Install them (search: Force Install Windows drivers" anywhere preferably YouTube

Thank you for your reply. As far as I know the official drivers were already installed. Because at first my device did show up listed when using the command 'adb devices' and I successfully flashed TWRP recovery. But to be sure I repeated the process:
- Connected my phone in fastboot mode (vol up + connect usb cable). The blue led lights up.
- Go to the device manager, right click on 'Android ADB interface' device and manually install the driver via 'Have disk'.
- The driver installs with no errors.
But still my phone is not listed and I cannot flash anything.
When the phone is in recovery mode it is listed using the 'adb devices' command. But when I'm trying to flash something I get the message <waiting for device> .
Ok, I restored my computer to a point before I started messing with my phone. After installing the official drivers my phone is still not listed (adb devices), but this time flashing did work. I managed to flash the AOSP 8.1 image. My phone is up and running again!
So I just got a QLink ZTE Z3001S and this thing is unflappable. I enabled OEM Unlocking under Developer Options, USB debugging to my PC, I believe I have the appropriate driver for the phone on my PC, and I just freshly reinstalled adb. When I open a command prompt in that folder, it's able to find the device with "adb devices", but when I try "adb reboot bootloader" it just restarts normally. I got some sort of recovery menu when manually holding volume down while powering up, but when I select "reboot to bootloader" it just boots normally, and connecting my PC to it and trying the command "adb devices" does nothing here. I also tried many different root programs anyway to no avail.
Well, I'm stumped. Any ideas?
