Recently, two family members began complaining about their HTC One M8 not sending or receiving text messages. It usually involved the text messaging app giving a message stating that the message couldn’t be sent. Now, the fact that two of the exact same phones started experiencing the same issue made me suspicious.
The Saga of Dealing with AT&T Customer Support & Tech Support
After going into an AT&T store for help, with one of the phones, we were given a new SIM card as a first attempt to remedy the situation. AT&T reps must be force fed SIM card replacements as a solution. This always seems to be their first solution for every possible problem from your phone not receiving calls to being run over by a car. A new SIM card was obviously not the solution so we moved on to calling AT&T.
AT&T customer support said they’ve been getting a lot of calls about the HTC One M8 lately. The rep said that the problem is due to a recent update from AT&T. This would make sense since both phones started having the issue simultaneously. Since customer support was unable to assist us, we were forwarded, further down the rabbit hole, to technical support.
Technical support provided us with a whole new story. They informed us that the phones had a hardware malfunction and that they are no longer recommending HTC phones since they are malfunctioning so much the past year.
The End of a Saga
We were told that if we put insurance on the phones, then we could submit a claim and get replacement HTC One M8 phones for both individuals. Another option they provided was to renew our 2-year contract, get a new phone and give the HTC One M8 back to AT&T. Both of these options were absolute rubbish. If AT&T tries this with you do not do it. Instead, do what I did to fix the problem. It might seem hard at first, but it isn’t.
Again, it sounds daunting at first but it isn’t. Before you move on, I want you to know what will happened below. First, we will download some files, then we will unlock the bootloader, flash a custom recovery, and flash a custom ROM and GApps to the device. Following these steps will erase all of the data on your phone and void the warranty. But at this point, your phone is probably no longer under warranty. If you’re worried about this, call your cell company and find out if the phone is under warranty.
Download the following files.
- Visit htcdev.com/bootloader and follow the instructions for unlocking the bootloader. If you’ve followed the instructions above, you’ll already have ADB and Fastboot installed, so you can scroll to the bottom of the page and click Proceed to Step 5… then finish following the instructions. (Linux users will need to run
fastboot flash unlocktoken Unlock_code.bin to unlock the bootloader)
- … after following the instructions your phone will reboot …
- Enable Developer Mode on your phone by going to Settings > About Phone > Software Info … or wherever it shows you the Build Number. Then tap the build number a bunch of times very fast until it says “You’ve enabled developer mode”.
- Now go to Settings > Developer Options and look for the option Android debugging and enable it.
- You should see a message pop up asking if you would like to allow a computer to connect to your device. Check the box to remember/always allow. Then click Allow
- Open the command line (terminal on Mac and Linux) and enter the following commands (replace
/path/to/ with where you saved the files).
adb push /path/to/cm-12.1-20151117-SNAPSHOT-YOG7DAO1K1-m8.zip /sdcard/ (your filename may differ slightly)
adb push /path/to/open_gapps-arm-5.1-mini-20160402.zip (your filename may differ slightly)
adb reboot bootloader … your phone will now reboot into an odd screen.
- We will now install the custom recovery. Enter the following commands
fastboot clear cache
fastboot flash recovery twrp-3.0.1-0-m8.img
- Once the command is done running, restart your phone and run the command
adb reboot recovery … your phone will restart into a screen that says TWRP. Swipe to the right to enter TWRP
- Tap the Install button and navigate to the cm-12.1 file which will be at the bottom of the list. Tap the file.
- Tap the Add More zips button and this time select the GApps file.
- Swipe the bar at the bottom to install the files
- Once it is completed after a minute or so, tap the button Clear cache/dalvik. Once that is done, reboot and you’re done!
