Any Motorola with a rooted device can tell you about the importance of bootstrap applications on devices with locked bootloaders. They can allow you to make tweaks to your phone, install recoveries, and do a number of other fun things to rooted devices that would not be possible otherwise. With the system architecture of Motorola phones, bootstrap applications can be the only way users can get certain things to work.
Safestrap is a Bootstrap / Recovery for locked bootloader phones. The goal is to avoid touching your primary system (I’ll call this 1st system) and only flash or make large changes to another place on your phone that Safestrap treats as a “2nd system” (in this case it’s the /preinstall partition)
Naturally, other developers enjoy tweaking previously created work, and the Safestrap application is no exception. In this case, XDA Senior Member Rick#2 has released a modified version of Hashcode’s creation to add certain features not found in the original. As Rick#2 explains:
Those of you who came from the Droid 3 might remember my customized version of Hashcode’s Safestrap, which included a console, improved user-interface, non-safe flashing, etc. I’ve finally got it to the point where I think it would be okay to release out in the wild. That being said, I’m not responsible for anything dumb you do to your own device. …
I’ve included statically compiled versions of “bash” and “vim” so that there aren’t any dependencies on the libraries usually found in /system/lib. Thus, you can use all of these utilities without having either /system or /systemorig mounted. You’re free to add your own binaries in your home folder, which is located at /cache/.safestrap/home, or just pop them onto your sdcard.
Also, I have a battery monitor running so it will tell you what level your battery is at, and have put a lot of work into the visual appearance of the user-interface. There are so many things I’ve modified that it would be impossible for me to list them all here.
