Are there any risks to rooting a device?




我看到了很多教程告诉我如何 root我的手机(摩托罗拉机器人),但其中没有一个潜在的"副作用" 。



  • 它是否有可能砖块设备?
  • 将它禁止我的保修?
  • 我会停止获取更新吗?
  • 警察第二天会在我的前门出现吗? (是的,我是面部的。)
  • 我应该知道的其他任何东西?



I see lots of tutorials telling me how to root my phone (Motorola Droid), but none of them mention any potential "side effects."

Aside from a few relatively minor issues that seem to require rooting to fix, I'm basically happy with the phone and therefore a little leery of messing with a device that cost me a lot of money and is only a few months old.

Assuming that I'm just talking about rooting, and none of the typical post-root actions (like installing a custom ROM), am I taking any risks by choosing to root?

  • Does it have the potential to brick the device?
  • Will it void my warranty?
  • Will I stop getting updates?
  • Will the cops show up at my front door the next day? (Yes, I'm being facetious.)
  • Anything else I should be aware of?

Does it have the potential to brick the device?

Although it has become relatively simple on the Droid, some methods of rooting pose more risk than others. So in short yes there is a potential.

Will it void my warranty?

It mostly depends on where you live and on your manufacturer (and their warranty policies). But technically this does void your warranty in most cases.

Will I stop getting updates?

Again this depends. Some manufacturer provide updates for rooted devices while others do not. These will usually continue to come in and may unroot your phone if you install them, or even require you to unroot manually before you can receive their updates. If you install a third party ROM, then there's nothing else to do with your original manufacturer.

Will the cops show up at my front door the next day?

I certainly hope not :) but if rooting involves cracking a bootloader, it could theoretically get you in legal trouble in some jurisdictions (anti-circumvention laws, etc.)

EDIT: Also be aware that there are different root methods based on which current build you are running.

EDIT: It may (as of May 24, 2017) prevent you from installing some apps: Google Play can now prevent rooted users from downloading certain apps






  1. 在下载root程序或发布root方法的位置发布一个线程。
  2. 在他们的问题和答案部分
  3. 下的
  4. 帖子。
  5. 搜索web 。其他人可能与你有同样的问题。







愿力量与你同在。不,真的,这是一个相对痛苦的过程,其中很多"轻松的一个触摸(UN)根工具" ,甚至那么那么有一个夸张的指南和来自 xda 引导您并解决您可能拥有的任何问题。但如果你对你的手机很满意,那么不要root。


Does it have the potential to brick the device?

Yes, it is possible to brick your phone, but should be very unlikely. Usually there is a way out of even what seems to be a brick.

If you do not know what you are doing and want to use the ADB method (entering shell commands manually) to root your phone, then be sure to follow all of the directions exactly as listed. If you somehow brick your phone, then it does not matter how good your phone insurance is with your cell provider; if they find out you rooted or attempted to, they will not fix it.

If you do somehow brick your phone, then do not panic. Try these things:

  1. Post a thread to where you downloaded the root program or where the root method was posted.
  2. Post to XDA under their questions and answers section.
  3. Search the web. Someone else has probably had the same problem as you.

It is quite possible to unbrick your phone, but it will take some time and patience to sort it out.

Will it void my warranty?

Yes. But in most cases you can restore your phone to a condition that they'll never know that you rooted your phone. And sometimes they do not even check to see if you rooted your phone when you return it.

Will I stop getting updates?

Yes and no. If you flash a rom, yes. But most likely that rom has constant updates (such as CyanogenMod). Also if you root and keep stock rom, you will still get OTA update notifications (but running an update will un-root your phone).

Anything else I should be aware of?

May the force be with you. No, really, it's a relatively painless process with a lot of these "easy one touch (un)root tools" and even then there is a plethora of guides and help from XDA to guide you and troubleshoot any problems you might have. But if you are happy with your phone just the way it is, then don't root.





Rooted phones are just as secure as an unrooted phones if you never grant root permission to any apps. The problem is that if you root your phone, you're bound to give root permission (otherwise, why are you rooting your phone in the first place), and applications that you give root permission may turned out to be rogue or leak their permission to allow an untrusted applications to gain root-like permission.

Running rooted phone is safe as long as you know which app to give root access and which are not. Problem is, even assuming that you only pick trustworthy apps they still can leak permissions inadvertantly (in security parlance, this is called confused deputy problem), so you must really be careful when choosing trusted apps.





Some malwares can escalate to root permissions even on a un-rooted phone. Like the one they just recently found in over 50 (popular) apps on the android market.

,您应该意识到它是一种安全风险。 root用户可以访问整个手机,包括其所有功能,以及所有运行应用程序的内存。后门可以安装在自定义ROM中。它甚至可能甚至不利,但你的手机可能成为僵尸网络的一部分。

Does it have the potential to brick the device? 


Will it void my warranty? 


Will I stop getting updates? 

Yes, if you install a custom ROM.

Will the cops show up at my front door the next day? 

Yes, but only if you're Chinese ;-). And even then, only if your police administration is near enough to Beijing.

And you should be aware that it is a security risk. A root user has access to the entire phone, including all of its functionality, and the memory of all running applications. A backdoor could be installed in a custom ROM. It might not even be to your disadvantage, but your phone might become part of a botnet.




是和否,有点取决于该方法:安装官方rooted ROM或设置切换是安全的。使用依赖于CPU错误才能破解内核安全性的脚本不是。


  1. OEM TOS(服务条款)。大多数主要的OEM都说你失去了保修。
  2. 在区域法下的有效性。例如,在EU中,在生根上声称保修空中的TOS无法强制执行。由于它,他们不能法律拒绝拒绝你的保证。但在最糟糕的情况下,您可能必须在法庭上与他们打架(尚未闻名)。


50/50 ,由OEM变化。在否定的情况下,您可以经常ofroot然后重新启动更新的版本。但并不总是。



  • 播放商店可以检测到它,可能会阻止您下载某些应用,但它不会阻止您在其他地方获取这些应用程序。
  • 具有root权限的应用程序可以对系统进行更多损坏,因此请注意安全威胁,请参阅这里

TLDR Version (2017)

Does it have the potential to brick the device?

Yes and no, kinda depends on the method: Installing an official rooted ROM or a setting toggle is safe. Using a script that relies on a CPU bug to crack kernel security isn't.

Will it void my warranty?

It depends on:

  1. The OEM ToS (Terms of Service). Most major OEMs say you lose warranty.
  2. ToS validity under the regional law. For example, in the EU a ToS claiming warranty voids upon rooting is not enforceable. They can't legally refuse your warranty because of it. But in worst case you may have to fight them in court to get it (unheard of as yet).

Will I stop getting updates?

50/50, varies by OEM. In the negative case, you can often unroot then re-root the updated version. But not always.

Cops? Other stuff?

No cops. Rooting is not illegal, anywhere. But:

  • the play store can detect it and may prevent you from downloading certain apps, though it doesn't prevent you getting those apps elsewhere.
  • apps with root permission can do more damage to your system, so beware of security threats, see here
