Hi

I bought a ZTE Open C, and unfortunately it frequently reboots when I answer or initiate a call. After the reboot it usually lets me retry the call succesfully, but it is very disruptive for answering calls

I have colleagues with the same issue who got the ZTE Open C at the same time as me. We work in a position where we take a lot of calls on our mobiles and we cannot see who calls (routed through a PBX) and so we cannot call back and it is very bad for customers :-/

I was wondering if there is an update to the dialer app, or if someone knows how I can maybe flash the phone to 1.4 FFOS or 2.0 or something ?

I've got an ZTE Open C with the Firefox OS. My problem is as such:

At random points the screen starts flickering when I try to unlock the screen, making it impossible to see or do basically anything. Then, at another random point it stops and goes back to normal as if nothing has happened.

What is causing this problem and what can I do to solve it??

Hi! I Install rooted firmware here: http://en.comebuy.com/developer-firefox-os-open-c.html. The main reason was to install Russian keyboard. Then I compiled and installed Gaia 1.3 with Russian keyboard. All Correct.

I learned that the new official firmware from ZTE already includes Russian keyboard. And I wanted to try it. However, I get an error when trying to flash the phone using sd card or Open_C_upgrade_Tool. Error is "E:failed to verify whole-file signature E:signature verification failed Installation aborted"

How i may restore default firmware?

My phone is using lots of data even at night when I'm asleep. My usage report says I have only used 167mb but AT&T says I have used almost 3gb. So I turned off the data on the phone and it stopped. My next test is the mail app. I have noticed when it checks for my mail at gmail it hangs and just keeps on spinning. I have to reboot the phone to get it to stop. So maybe the mail app is chewing through my data when it gets hung up.. Any ideas?? I love the phone just wish it would not use 30mb an hour.

Thanks for your help.

Softbricked ZTE Open C after flashing Gecko & Gaia v1.4

Hello,

Not-quite-happy user of ZTE Open C here. This happened as follows: I've downloaded the rooted firmware from comebuy.com. The main reason was to install Russian keyboard, which I managed to do by building and flashing Gaia. The Gaia was from v1.4 branch, and some apps didn't work properly (camera & keyboard, in particular). Then I did the fatal mistake, it seems - instead of returning to v1.3 I decided to build & flash Gecko from v1.4. Almost everything worked fine except that I hit some bug where SIM card wasn't working at the start but switching airplane mode on&off fixed the situation. However, after a reboot, the screen just turned off right after showing the splash image of the fox. At that point, the system still booted into normal mode, so I tried to recompile Gaia again and flash it onto the device. And then only the recovery mode became available =\

Then I tried various things, and the current state is:

  • recovery & bootloader modes work
  • updates can't be applied, failing with 'E: signature verification failed' for both rooted and official firmware
  • fastboot flash doesn't work, printing the message "FAILED (remote: flash write failure)" every time
  • adb shell doesn't work - first it was barking about the wrong permissions (- exec '/system/bin/sh' failed permission denied (13)), by now I have erased the /system partition altogether using fastboot because adb push printed an error about no space left on device, and I thought maybe erasing some partitions will help (that was way too naive, I must admit...)

Now I wish to return to the original firmware, either from ZTE website or comebuy.com. The most adequate way seems to be applying an update from recovery mode, but the verification failure has to be circumvented somehow.

Any thoughts?

1. when I set the alarm this works erratically, is activated at the scheduled time and then comes back on at different times even when it was disabled.

2.-The consumption meter data is eventually restarted.

3. Lowering the brightness to the screen, it works while you are using the ZTE OPEN C. When goes to sleep and re-enter the brightness starts and stays full even when I check the control over it and is on low gloss position.

I bought the device for developing purposes and just got it today. I am a US user by the way.

I followed the directions that are listed here for how to root the device and unlock the bootloader, however, the directions do not work.

I now have a rooted terminal using adb shell, however, when i reboot to the bootloader and run fastboot devices I get nothing, and no other fastboot command works.

This is absolutely ridiculous. I bought the phone from the ebay site just this week using the link here on Mozilla. I've even synced and built B2G for the device. But I can't unlock my bootloader? Defeats the purpose of "open" and makes me regret my purchase.

I would appreciate some help in this matter promptly.

This morning I discovered huge amount of traffic consumed by FF OS (leading to about 300 euro loss). Update history shows that the phone updated itself this night, and 3G was turned on.

WTF? I thought after checking for updates the phone should notify the user first, so that they can turn Wi-FI on. Is this not the case?

I have ZTE Open, bought last November, works wonderfully, but... just in the past 2 weeks I have noticed that when I have wifi turned OFF, and 3G turned ON, and the phone in airplane mode (must do this when at work) the phone still connects to the available wifi !! Very inconvenient as we are not supposed to use our phones at the office, and the phone bings! to let me know it connected to a wifi. Now I have to turn it off completely. Anyone have the same problem or know what to do? Thanks

Hi,

On the official upgrade instructions on the dev wiki, it's fairly simple to upgrade to FXOS 2.1. However, because the build system is now based on Android KitKat, I can't install the latest images on my phone, as it just bricks it and I need to wipe it and start again. Is there any way to upgrade, or am I stuck?

Also, what's the difference between "flame" and "flame-eng"?

Thanks.
