can't install ZTE supplied 'update' after flashing compiled B2G

My device is running version 1.3.0.0-prerelease that was compiled from source (by someone else). Now ZTE has finally released a version 1.1 'update' that I would like to install. However, when I attempt to install the update I receive a signature verification failure error message. How do I install the update provided by ZTE?

Re: can't install ZTE supplied 'update' after flashing compiled B2G

Hi jezra,

Thank you for your question, to better assist you:

  • Does the phone have a provider? If so, the update may not be available for that carrier.
  • What build is on the phone, and is this the ZTE Open that was purchased before or after 9/27/13 ?
  • Would you mind providing a screenshot of this error: "signature verification failure error message"
  • What steps are you taking to flash the phone?

[Manual update attempt results in download error - zte open firmware V1.01.00.01.019.120]

Added: If it is a developer phone there should be a push this week, however I am suspicious since 1.3pre version that is on there now was flashed on, 1.1 may need to be flashbooted onto it. For clearer instructions on how to do this I would ask [https://www.stackoverflow.com] or mdn.com= [https://developer.mozilla.org/en-US/F.../Building] - ZTE Open Orange phone is the Inari.

The device is a rev1 ZTE Open purchased on Ebay, and the fastboot update has been enabled.

The current OS is 1.3.0.0-prerelease and the build identifier is 20131007083940

To flash the phone: 1. I have downloaded the latest zip file from http://www.ztedevices.com/support/smart_phone/b5a2981a-1714-4ac7-89e1-630e93e220f8.html?type=softwar... 2. I unzipped the file 3. after unzipping, I moved the included zip file to the top level of my device's SD card 4. I reboot the device and hold down the power button and the volume up button 5. from the menu that appears, I select "apply update from external storage" 6. I then select the update zip file and press the power button


I will try to find a digital camera to get a screen shot

I managed to get the device to install the update after removing and formatting the SD card and then copying the update file back to the SD card.

Hi jezra,

I asked about the verification error earlier today and this error happens when a file is missing or a check is not complete for a build, so they recommended to do a fresh install after a hard reset. Glad to hear that this worked after reformatting the SD card.

Re: can't install ZTE supplied 'update' after flashing compiled B2G

Unfortunately, after the "update" I am no longer able to use fastboot to install compiled images. I can still use `adb reboot bootloader` to get into fastboot mode, but when I try to write to the device, the device restarts and exits fastboot mode, and this causes the write to fail.

Same problem for me. The update to 1.1 works but after that i'm not longer able to flash my phone.

./flash.sh ... writing 'userdata'... FAILED (status read failed (No such device))

I read stuff speaking about that the device is not reboot in the right mode but i can't find a solution for that.

I've tried to install the previous v1.0 'update' in the hopes that the ability to use fastboot would be restored. Unfortunately the update behaves like a ZTE update and won't install due to a signature verification.

Jezra, what do the lines say above the "Signature Verification Error" there should be a file there?

This will help what is causing this verification issue.
