The update is pushed OTA (over the air), in stages
The international HTC One S already received the Android 4.1 Jelly Bean upgrade a few months ago, but some carrier-bounded models have yet to get the promised update.However, the Taiwanese handset maker launched a slightly different version of HTC One S last year, which was only available for purchase in several countries.
This particular HTC One S features a previous-generation Qualcomm Snapdragon S3 processor inside instead of the latest generation Snapdragon S4 CPU.
Given Qualcomm’s production difficulties, HTC was forced to swap the processor inside the standard One S with an older one.
The HTC One S with Snapdragon S3 processor is sold only in Asia-Pacific regions and some European countries, so it’s not widely spread. The CPU is clocked at 1.7 GHz, whereas the standard HTC One S sports a 1.5 GHz dual-core processor.
Anyway, when HTC announced the Jelly Bean update was available for the international One S devices, it didn’t mention anything on the S3 model.
Even though HTC One S with S3 CPU owners have been left out from the initial Jelly Bean rollout, it appears that they will now receive the upgrade before other carrier-branded One S units.
According to HTC insider LlabTooFeR, an Android 4.1.1 Jelly Bean update is now available for HTC One S (S3 CPU) devices.
The update is about 600MB in size, so it’s recommended to use a Wi-Fi connection when downloading it. Users should make sure their phone’s battery is fully charged and that they have backed up their personal data.
It appears that the update is pushed OTA (over the air) in waves, so not all HTC One S (S3 processor) owners will receive it at the same time.
Keep in mind that besides bringing the phone’s firmware to Android 4.1.1, the update will also upgrade its user interface to HTC Sense 4+.
