Wait, the xiaomi one is weird. You have to pass an actual, 'notoriously difficult' test? What are they testing?

https://github.com/MlgmXyysd/Xiaomi-BootLoader-Questionnaire https://github.com/MlgmXyysd/Xiaomi-BootLoader-Questionnaire here are some past papers. For example: https://github.com/MlgmXyysd/Xiaomi-BootLoader-Questionnaire/discussions/238#discussioncomment-12299739 https://github.com/MlgmXyysd/Xiaomi-BootLoader-Questionnaire... Regarding the Service in Android's four major components, please do not select the correct statements from the following [Multiple Choice Question] 1. Service must perform time-consuming operations in the main thread, otherwise it may cause stuttering 2. Among Android's four major components, Service runs in the background and definitely will not block the main thread 3. Service's lifecycle does not depend on the Activity that starts the Service 4. A Service can only be started once; multiple calls to the startService() method have no effect 5. Service can use the stopSelf() method to stop the service Since 1,2,3,4 are wrong, but the problem asks "do not select the correct statements", you need to choose 1,2,3,4. It show not only how hard the problem, but they also play on words. You also need to answer 13 questions in 15 minutes. And scoring more than 85 points to have a chance to unlock it. https://www.bilibili.com/video/BV1jPbXzaE9d/ https://www.bilibili.com/video/BV1jPbXzaE9d/ Because the exam difficulty is too high, some people even go to official repair centers requesting a downgrade, and snatch the phone when the technicians unlock and reflash the firmware. UPDATE: fix the score requirement and the correct answer.

  Wow, that’s certification level with extra traps on top. >Because the exam difficulty is too high, some people even go to official repair centers requesting a downgrade, and snatch the phone when the technicians unlock and reflash the firmware. Are people that interested in unlocking despite the high friction? Honestly, I’m impressed.

    I don't know how popular of unlock, but AFAIK, they want to remove bloatware (like the Scam Protection APP from government, or Advertisement APP from mobile carrier), unlock hardware restriction (higher refresh rate) and some other reasons.

  Subject to the accuracy of the translation, you are guaranteed to answer that one correctly by not selecting any options. That is because the instructions do not constrain what you may do about incorrect statements. Thus, in a purely logical sense, you must not select any correct statements but you may select or not select incorrect statements.
