Recently I just downgraded my busybox to 1.18.2 version using the jRummy's BusyBox Installer. I was previously having busybox preinstalled by CM7.2 custom ROM.

Then I immediately tried to install the latest, 1.19.4 version using the same app..

It could have shown some error message, but I wasn't sure. Maybe the download didn't proceed fully. But now onwards, I am getting "No root" message when I try to launch the BusyBox Installer. I tried everything, forgetting the app from SuperUser (by chainsfire) app and reauthorizing root for it, clearing data, rebooting the phone etc.

Apps like link2sd also cannot get "root" privileges all of a sudden!!

Strange thing is, z4root app detects my phone as already rooted. And when I try to click "re-root", the process goes on and on and nothing happens.

Why has this happened? Is this because JRummy's busybox overwrites the CM7.2 build one? Should I never try updating busybox when I'm on CM7.2? or is it because I have to specify correct path? /system/xbin in that busybox installer?

Now all I need is to make busybox and more importantly, get my root back to work properly hopefully without having to reinstall my ROM. Any ideas?

Huawei IDEOS u8150 running Cyanogenmod 7.2-RC1

Update : I tried rooting/unrooting etc using SuperOneClick v 2.3.3.0. It doesn't work either. Here's its log (apparently there are lots of "illegal instruction" errors where it shouldn't be):-

* daemon not running. starting it now on port 5037 *

  • Why would you upgrade your busybox? Do you spend so much time in shell?

  • @RichardBorcsik I was trying out the SuperCharger V6 Script from the XDA and this tutorial said 1.18.3 or newer busybox would cause trouble.. hence I downgraded from my 1.19.x CM7 build. No, I don't spend much time in shell. :)

You should never mess with the system without having a backup.
To get root back you can just re-flash the rom that you're using without wiping anything. This will remove whatever happened with your busybox.

  • This is what I am doing right now.. lets see if it solves the problem hopefully.I am not very concerned which is why I don't bother about backups in the first place; here I was just asking if there was some other easier way to solve this problem and perhaps that would give me more insight into the android system.Personally I believe upgrading/downgrading busybox shouldn't cause corruption like I encountered.

  • @Power-Inside No it shouldn't cause, but it shouldn't be updated while it's running either. These xda script warriors who instead of bundling their own busybox for their 'fixes' make you modify your system when it's unnecessary cause a lot of bricked phones and trouble.

  • I guess this is the best solution.. re installing took a little bit of time which included the time to download the ROM, lol. But it fixed everything neatly quite well.
