Update HTC One GSM to CM10.2 Jelly Bean 4.3 custom ROM

HTC One (GSM variant) sees itself face to face with Android 4.3 Jelly Bean via today’s update tutorial which uses CM10.2 Nightly Build custom ROM.

If you have never had to deal with a custom ROM, then you should be told that such a tool generally comes with many attributes. All of them work together toward making your phone give its best performance-wise.

Requirements

Before the upgrade can happen, you should consider this set of requirements:

How to install CyanogenMod 10.2 Nightly ROM on your phone

  1. Plug the smartphone to your notebook after the tow update files are on the latter’s desktop, then take those packages (don’t unzip them) to the handset’s SD card root.
  2. After the transfer is completed, you can unplug the phone from the PC. Then switch the HTC One off and after that enter the phone into Recovery Mode by pressing + holding, simultaneously, Volume Down + Power; when the phone boots into HBOOT Menu, you should opt for “Recovery” from there.
  3. In the Recovery Menu you should choose some very needed options. Here is what you need to do: choose “Factory Reset/Wipe Data“, opt for “Yes“, wait for the confirmation to be done, go to the Recovery Menu, opt for “Wipe Cache Partition” from there, then choose “Wipe Dalvik Cache” which is under an option called “Advance“.
  4. After you’ve performed these wiping actions, you should select these options: “Install zip from SD card” and after that “Choose zip from SD card“. The cm-10.2-20130826-NIGHTLY-m7ul.zip file next. Then press “Power” to have it opted for, then confirm the flashing.
  5. After this is over, you need to flash the Gapps .zip file by repeating all the steps which installed the CyanogenMod 10.2 firmware.
  6. Then, once the flashing of both packages has ended, you need to reboot the handset by first going to the Recovery Menu and from there choosing the “Restart” key.
  7. After a wait of no more than 15 minutes, the HTC One will have been updated to the CM10.2 custom ROM that brings the Android 4.3 Jelly Bean version on your smartphone. Speaking of which: go and explore this OS by launching “Settings” and then choosing “About Phone“.

NOTE: Now that you have an upgraded device, the world is yours! Brace yourself for a multitude of custom ROMs, tweaks and such that can greatly enhance your user experience.

If one day you realize this is not for you, then return to the old ROM of your phone. Attain this by doing the following: boot your HTC One GSM into Recovery, opt for “Backup&Restore” and look for your ROM on a list which will pop up soon enough. Then select said tool.

Should your phone annoy you with “Status 7 error” message: locate a kernel that works with your device, flash said kernel on it and then install the CM10.2 Nightly Build ROM on the HTC One.

If there is a boot loop going on (or your phone is stuck on boot), you have to: opt for “Wipe Cache Partition“, then choose “Wipe Dalvik Cache“. Now restart the phone and the problem will be gone at long last.
