How to fix Huawei Nexus 6P No Service issue

No Service error can be caused by a number of factors. To fix it, you must follow a set of troubleshooting steps.

Install system update

Before you do any troubleshooting steps, be sure to check for any available system updates. Some network errors are caused by modem firmware bugs and the only way to fix them is by installing an update.

Clear system  cache

Making sure that your Nexus 6P’s system cache is in top shape is a must. Sometimes, bugs can develop if the system cache is outdated or corrupted. To refresh the system cache:


  1. Turn off your phone.
  2. Press and hold Volume Down and Power simultaneously until you see the boot screen
  3. Use Volume Down to navigate to Recovery Mode
  4. Press Power to confirm
  5. Wait until you see the Android robot then hold down Power. Press and release Volume Up.
  6. Navigate with Volume Down to the Wipe Cache Partition option.
  7. Press Power to select.
  8. Use Volume Down to highlight the Yes option.
  9. Press Power to select.
  10. Press Power to reboot your Nexus.

Manually change network type

In some cases of Nexus 6P showing No Service error, manually opting for another network type helps. This can be due to the fact that the device is forced to clear out its current cellular settings during the change. To change a network type:

  1. Open Settings app.
  2. Tap More.
  3. Tap Cellular network.
  4. Tap Preferred network.type.
  5. Select 2G or any other type other than the one you’re phone is using.
  6. Restart your Nexus 6P.
  7. Repeat steps 1-4.
  8. Select 3G or 4G (depends on which one is available)
  9. Select Network Operators.
  10. Tap Search Networks.
  11. Select your carrier and wait until your Nexus 6P reconnects.

Reseat SIM card

In some cases, temporarily disconnecting the SIM card helps in fixing the problem.  Make sure to turn the phone off before removing the card. After a few seconds, reinsert the SIM card while the phone is still off. Then, turn the Nexus again and see what happens.

Check SIM card

To check if you have a SIM card problem, you can insert it to another compatible device. By compatible we mean a phone that is provisioned to work for your current network. If you insert the SIM card to a phone that’s not unlocked to work with your network, you won’t know if there’s a problem with card or not.

Reset network settings

If the SIM card is fine, the next best thing to do is to ensure that you reset your phone network settings. Doing so will clear cellular settings and other network settings. This won’t erase any personal data so it can be done safely.

  1. Open Settings app.
  2. Tap More.
  3. Tap Network settings reset.
  4. Tap Reset Settings.
  5. Note If prompted, enter the PIN, password or pattern.
  6. Tap Reset Settings to confirm.

Factory reset

The most that you can do as an end user is to return all software settings to their defaults. Factory reset is often effective in dealing with software bugs. If the reason for the No Service error is software-related, factory reset may help. Here’s how it’s done:

  1. Create a backup of your personal data.
  2. Open Settings app.
  3. Tap System.
  4. Tap Advanced.
  5. Tap Reset options. If you don’t see “Advanced,” tap Reset options.
  6. Tap Erase all data (factory reset).
  7. Tap Reset phone.
  8. If needed, enter your PIN, pattern, or password.
  9. To erase all data from your device’s internal storage, tap Erase everything.
  10. When your device has finished erasing, pick the option to restart.
  11. Set up your device and restore your backed-up data.

Possible solutions

While regular troubleshooting usually stops with factory reset, some cases may involve doing two other solutions. These options though are only limited to cases wherein a user has previously tampered with the device’s official software by rooting, installing apps from non-Play Store sources, or flashing. Since such users are aware of the risks involved when tweaking system software, we assume they know how to find their way in sometimes confusing world of Android troubleshooting. If you did tamper with your device’s software before the No Service error occured, consider doing these two solutions:

  • IMEI repair
  • Flashing of stock firmware
