Welcome to the EternityProject's Motorola RAZR Bootloader Bypass Thread!


What do we have today?
Kexec. After working with a really good developer, [mbm], finally this has become real.
Linux boots Linux. No signature checks.
Yeah, this is the beginning of custom kernels :)
Oh, remember that this is still a WORK IN PROGRESS!

Known issues (to be solved):
- CPU1 doesn't come up.
- It fails on (some?) CDMA Droid RAZRs :(

ToDo (by priority):
1. Fix CDMA Droid RAZR problem
2. Fix CPU1

Disclaimer:
The EternityProject and [mbm] aren't responsible of anything you do on your device: if it explodes and kills you, or if it comes to life and becomes something like Terminator, it's YOUR OWN RESPONSIBILITY.
Plus, prior complaining that it doesn't work, use a STOCK MOTOROLA ROM. Thanks.

Tested on:
651.167.19.XT910.Retail.en.FR
651.167.26.XT910.Retail.en.EU
65.1.40.XT910.MERetail.en.06
651.73.250.XT910.Brasil.en.BR

Installing:
1. Copy the package on your internal memory / MicroSD
2. Boot the bootstrap recovery
3. Install it via that recovery.

Booting with kexec:
Open a terminal emulator or ADB and enter this:

Then wait for 10 seconds to jump over the new kernel. Now your device will vibrate and apparently freeze. Wait a minute and you'll be on the new kernel ;)
You can also set the script above to be automatically executed at boot time or to be a one-tap script with apps like Script Manager.

In case of freeze:
VOLDN+POWER (press for ~10 seconds) will hardshutdown your device. If it freezes during the kexec boot, retry. Sometimes it can happen.

In case of slow-like-hell device:
Install SetCPU or AnTuTu CPU Master and change your governor from 'mot_hotplug' to 'ondemand'.

Note:
If something is not working, please remove anything that is automatically running at boot, like auto-recovery and the "Set on boot" option of SetCPU or AnTuTu CPU Master.

His original post on his website and this post says it wasn't developed or tested on cdma (prob cause he doesn't have one). If you haven't tried you don't know either.

I wasn't being rude, the very first comment on this thread says "Can't wait for the CDMA version." What does that tell you?

He does have one, we gave it to him as part of the last developer giveaway. As hard as it is, that's all I'm going to say...

Shameless promotion for Tapatalk v2 on some mobile device

Never said that I haven't tested it on CDMA.
I said that we're still working on it. Don't worry.
