Akhilesh Chowdary Bojedla 21 Report post Posted September 29, 2014 The process is more or less similar to that of htc one m7. So for those who already unlocked sprint htc one m7 this should be familiar. Requirements: 1. This tutorial is independent of Android version whether it may be 4.4.2 or 4.4.3. Works on both stock and sense based custom ROM's. (Not tested on AOKP ROM's.). Works on both s-off and s-on devices. 2. You need to be rooted and bootloader needs to be unlocked. Here are the links that would show you how to do it. http://theunlockr.com/2014/04/19/root-htc-one-m8-all-in-one-toolkit-method-video/ '> https://www.dropbox.com/s/74r6h5q6ft50z6j/SIM_UNLOCK.zip?dl=0 '> https://www.dropbox.com/s/74r6h5q6ft50z6j/SIM_UNLOCK.zip?dl=0 4. Download and install Terminal from play store. 5. Switch off the handset and boot to fastest.(By holding volume down and power button together ). 6. Once you are on fastboot screen navigate to recovery using volume buttons and press power button to boot to recovery. 7. One you are in recovery click on install (I'm presuming you installed twrp recovery, if not then do it according to that recovery). Now locate SIM_UNLOCK. zip and flash it. Reboot system after successful flash. 8. On Reboot:Open the Terminal Emulator from the app drawer 9. Type - su 10. Hit enter on your keyboard 11. After you see the # type this- am start com.redbend.vdmc/com.htc.omadm.test.TestMainActivity 12. Hit the enter key 13. Next you should see a menu listing 3 options as follows: GUI API ROAMING OPTIONS 14. Select API 15. Once the API menu comes up, scroll down until you see - sim lock 16. Tap- sim lock. Wait until the gray highlight goes away and turns black again 17. Reboot and you are done. 18. If you see you that you have no network then dial *#*#4636#*#*. A menu will pop up. Select phone information then scroll down until you see 'select preferred network type'. Change it to WCDMA preferred and that is. Now your network should pop-up. This is permanent unlock and you can update your Android version in future. Thank you. 7 Share this post Link to post Share on other sites

Akhilesh Chowdary Bojedla 21 Report post Posted September 29, 2014 @OP Is it possible to get native hotspot on stock rom for Sprint M8? Im seriously considering M8 as my next phone. Yes hotspot does work on sprint m8. But the max users that you can connect to hotspot is limited to 1(due to data roaming). But you can use some 3rd party applications.

Akhilesh Chowdary Bojedla 21 Report post Posted October 1, 2014 Yes s-off required. Sunshine tool can do it. I tried firewater but it didn't work for me. You can try your luck though. I think those who have 4.4.2 can get s-off through firewater. Share this post Link to post Share on other sites

I think those who have 4.4.2 can get s-off through firewater. Yeah. It depends on the Hboot version. Hboot x.x7 is not firewater sOFFable yet.
