Huawei officially stopped giving out bootloader unlocking codes. Period. Full stop. The only way the dubious sites like funky monkey and other rip off sites are getting the codes for you are through some of the greedy Huawei employees who have access to the phone services to provide the codes. These people join with the other rip-off sites like funky to send you the codes. They are expensive, because people rushing to unlock and willing to pay any money. Part of the mponey goes to the leaking employee and part to the rip-off sites.
It was not like this before. XDA initially was a dedicated community on giving tutorials and contributions towards making the best of our phones. But with more companies blocking bootloader unlocking, everyone started to become greedy. We already paid so much for this Mate 20X and still willing to pay to get the unlocking codes to rip off sites?
Even after rooting, there is no proper support for this phone with other apps because of the locked bootloader limitations. Developers can't freely experiment and tinker with this phone because the codes were expensive once, and now there are no more codes, possibly because the employees concerned were fired and these rip-off sites are unable to get the codes from them.
Even custom roms do not have support for this device, or at least fully working ones, because of this.
When will you guys learn? Wake up. Don't fall prey to the scams. Don't pay just because you can and promote this new trend.
The only lesson I learnt is to do research next time BEFORE buying a phone and make sure that bootloader unlocking is supported by the company.
As for me, I already bought this and the only reason I wanted to root is because of removing phone-wide ads. Right now, I am okay with DNS66 which does not require root. It works well, though I need to restart the service manually Otherwise this phone is perfect, and I can always have official OTA updates without breaking anything.
