Download latest build here: https://dwnld.aicp-rom.com/
### Localisation (GPS) must stay turned ON to get Telephony
Or try crDroid 7.12
- NikGapps-SL ARM64 Core or Basic: https://sourceforge.net/projects/nikgapps/files/Releases/NikGapps-SL/
- Charge phone to 100%
- 8+ GB MicroSD card formatted in FAT32
- Copy ROM + Google Apps +/- Magisk root zipfiles without unzipping content. Insert microSD in phone.
WARNING. This tutorial uses Microsoft Windows.
WARNING. Warranty is now void.
WARNING. Read carefully the sentences starting with ###.
2) BACKUP DATA AND INSTALL DRIVERS
Disable Antivirus.
Install drivers from my pack:
right click on HTCDriver.exe > click on Run as administrator and continue the setup.
Connect HTC One (while phone on) to PC, let drivers install.
In Windows explorer, HTC One should be available.
### If not make sure phone connection is in File transfer mode (see Android notifications).
### Phone is still not visible in Windows Explorer ? See fix at end of tutorial.
Collect all personal photos, videos, etc ... and backup these on PC.
Use an app like Backupyourmobile/SMS Backup & Resotre to backup texts, contacts, etc.
Check that backup is located on microSD card.
Then copy the backup on your PC.
Disconnect phone.
### If your phone is Simlocked/carrier locked/Network locked, don't go further.
Visit official website of your network carrier (or call their support) to retrieve your desimlock code.
Ask them for details on how to remove simlock.
How do I know my phone is simlocked ? When you insert a SIM card from another operator, network is inaccessible.
Only a stock ROM can remove simlock.
To go back from custom ROM to stock, see dedicated section at the end of tutorial.
2) KNOW YOUR MODEL
Shutdown phone.
Start in fastboot mode: hold Power + Volume- until it vibrates and release both buttons.
Wait until hTC download mode shows up.
On mine I see:
SECURITY: *** UNLOCKED ***
model: htc_himawhl
CID-11111111
SECURITY UNLOCKED means S-OFF for SECURITY-OFF, otherwise S-ON. With S-ON you can upgrade firmwares but cannot use previous versions.
3) UPGRADE TO LATEST OFFICIAL ROM
In Android, go to Settings > About > Software information.
Android version is 7 and HTC Sense version is 8.0.
If Android is already 7, go to next chapter.
But before, search for IMEI and note this number somewhere safe (we never know).
Otherwise, we need to flash suitable stock Android 7 Nougat firmware, depending on your model.
In Settings > About > Software information, note down Software version (in case of future error).
For me it is 3.41.651.4 (651 is the SKU part, meaning Sprint US ROM).
See Sneakyghost's and Behold_this' SKU-, CID- and MID-List: https://docs.google.com/spreadsheets/d/10H7RftecZZKb5tT2zpShfYNFAfSe-imhhqtVfeMPVDA/edit?pli=1#gid=0
Now tap on More > tap 7 times on Build number. It unlocks Developer options.
Go back to Settings menu, you can see the new Developer options menu.
Tap on it, accept the warning.
Switch ON USB debugging option.
Connect phone, a message appears on phone : Allow USB debugging?
check Always allow and confirm by tapping on OK.
But before upgrading to Android 7 Nougat, you need the latest Android 6 official ROM available for your model.
- Himaul or Himaulatt: RUU_HIMA_UL_M60_SENSE70_ATT_MR_NA_Gen_Unlock_3.35.617.16.exe
- Himaultmus, not sure you can get Android 7: http://downloadmirror.co/android/29Ri/RUU_HIMA_UL_M60_SENSE70_TMUS_MR_TMOUS_3.39.531.7.exe
- Himawhl: https://www.androidfilehost.com/?w=files&flid=334967 or https://downloadmirror.co/1KrL/RUU_HIMA_WHL_M60_SENSE70_SPCS_MR_Sprint_WWE_3.41.651.21.exe
- Himawl: http://downloadmirror.co/android/29...0105_CNV_1.26_002_release_469809_signed_1.zip
RUU*.exe: launch installer, connect phone (from within Android started or in Download mode) and follow executable steps.
Wait during flash.
After reboot, you have access to HTC software updates.
Go to Settings > System updates > HTC software update > CHECK NOW
Install available updates.
Repeat after each update until update 4.x is fetched.
Here you go with Android 7.
### I succeeded with Sprint model, tell us here if you experience problems with other models.
### Flash a RUU in *.zip format
### Copy RUU zipfile to microSD card and insert in phone. Shutdown phone.
### Start in fastboot mode: hold Power + Volume- until it vibrates and release both buttons.
### Use Volume- to Reboot to Bootloader. Confirm with Power.
### Use Volume- to BOOT TO RECOVERY MODE. Confirm with Power.
### Once in recovery, use Volume- to: Apply update from SD card
### Use Volume to select RUU zipfile
### Wait during flash
4) UNLOCK BOOTLOADER
Save IMEI, go to Settings > About > Phone identity > IMEI (15 digits).
In Settings > About > Software information > More.
Tap 7 times on Build number. It unlocks Developer options.
Go back to Settings menu, you can see the new Developer options menu.
Tap on it, accept the warning.
Check ON OEM unlocking and USB debugging options.
Go to Settings > Security > Screen lock > None
Go to Settings > Storage > Phone storage, scroll down and make sure Phone storage encryption is unchecked.
Now, open a Windows command on my "flash" folder (hold Shift + right click on folder -> Open a windows command here).
Or type cmd in Windows address bar and hit enter to launch a Command prompt in actual folder.
Enter command :
, confirm by pressing Enter.
Command returns :
### If no device is found, uninstall and reinstall properly the drivers while antivirus is off. Or see fix at the end of this tuto.
### Or start fresh on another PC.
Now type :
Phone restarts in Fastboot mode. Wait till phone screen is blank in fastboot mode.
Use volume keys to switch to Download mode !!!
### With HTC One M9, fastboot commands have to be sent from Download mode (took me hours to figure it out, thanks @DigiGoon).
Type :
Command returns :
### You may have to fix drivers again (see fix at the end of tuto)
Type :
, confirm by pressing Enter.
Command returns multiple lines.
Select with your mouse all the lines from
(included)
to the line
(included).
Now on keyboard copy (Ctrl + C combo), then open Notepad.
In Notepad, paste those lines (Ctrl + V combo).
Now manually remove all the (bootloader) strings from each line.
Your notepad should now look like this :
