Here’s a step-by-step tutorial on flashing CyanogenMod 12.1 Android 5.1.1 Lollipop custom ROM on the international Huawei Honor 3C (H30-U10) smartphone. This is an unofficial build in beta phase but it still offers full-fledged material interface on top of everything else.
We’re all excited to see our (old) Honor 3C finally getting its much-awaited KitKat based Emotion UI 3.0 update outside China. This update, numbered B320, is currently being rolled out in Malaysia but since all South Asian models carry the same market number, you can get your hands dirty on this update too.
Sometimes it so happens that even after successfully installing the Chinese KitKat firmware on international Honor 3C (H30-U10), you encounter a strange network issue that results in total loss of signals with ‘No Service’ onscreen message. This is actually engendered by the loss of phone’s IMEI data during the installation of unofficial ROMs/firmwares. The good thing is that you can easily bring back this IMEI with a minor patch using our concise step-by-step tutorial given in this article below.
You’re probably reading this post either because you bricked your new Huawei Honor 3C while installing the sloppy Chinese KitKat firmware that is available online and ended up with a dead phone or you just want to revert back to the original Jelly Bean OS and wait for KitKat update to arrive via OTA in your region. Whatever the reason, you should have created a system backup/dump in the first place. Still however, you can easily restore your device back to its stock Jelly Bean firmware using a brief step-by-step tutorial I’ve put together in this article – no matter if you’ve got a backup or not.
Since the international version of Huawei Honor 3C (H30-U10) comes with a locked bootloader, it is always recommended that anyone who wants to try out the Chinese KitKat firmware on their device should get their phone’s bootloader unlocked first to avoid soft-bricking. In this article I’ve put together a concise step-by-step tutorial on how to safely unlock the bootloader using the good ol’ SP Flash Tool.
