[boot.img] obsolete please lock

[Harry GT-S5830]

Hi all. Quick notice:

Usual disclaimers apply.

This is an Unsecure boot.img I made for Android 4.2 on the Nexus 4.

Okay cool... but what is an insecure boot.img?

An insecure boot.img allows the device to be booted with permissions to be mounted as root. This is a way of being able to push SuperSU/Superuser.apk to /system/app and the Su Binaries to /bin

adb shell
su
mount -o remount,rw /system
exit​

To use this you must be unlocked, not familar with unlocking a Nexus device? Easy. In fastboot mode type "fastboot oem unlock" this wipes all data on the device (virtual sd included).

A nice article regarding this thread was published here: http://www.addictivetips.com/android/root-google-nexus-4-install-clockworkmod-recovery/

To boot this boot.img:
must be in the platform-tools folder in the android-sdk
must be in fastboot mode (power+vol-)

First use: fastboot boot "boot.img" (no ")
Why boot? I have not tested this image as I don't have a Nexus 4 as of yet.**

**Some users report flashing the image makes the phone in need of a fastboot stock flashing session, stick to booting for now.​

Thank you for helping!

This is mainly for development purposes to obtain root on this device, it will be an easier process when a recovery is published and you can flash a su.zip. (see attached)

Note, this is in Nexus 7 folder as Nexus 4 does not have its own atm.​

Please Lock!

Anyone able to get me recovery.fstab from recovery image and ill try make a cwm6 touch recovery for us.

I wouldn't be lazy and do it myself but PC is off
Sent from a phone

sgs2ext4 doesn't work on the recovery.img and the image isn't mountable by itself in Windows.
Too lazy to reboot into Linux, for now.. any other way to crack it open?

I've got the recovery.img, can I get the .fstab out without loop mounting? I don't have a linux machine set up right now.

I could probably do it without this, but it probably wouldn't mount data/media (what emulates the SD) so it would be relatively useless as that's where zips are

Also this might prove useful: http://forum.xda-developers.com/showthread.php?t=1494036 (requires Cygwin or Linux environment)

Hell, I wouldn't trust myself to rip it out with a hex editor. I'm setting up a VM right now, but I could just upload the recovery.img for you. I pulled it out of the stock image that google uploaded today.

Cheers, that's where I had mine but I corrupted it :/ ill try pull it apart on the 600MHz wonder pico

Or perhaps not... 3.2" is too small for hex

Lol, I'm having a hell of a time getting Slax as a cooperative VM, might have to go all out with ubuntu

Got it!
Thanks for the tutorials. It was just fun to to something short after midnight (Germany). I was a little bit bored Would be nice if you can mention me in the people helped to create this recovery

That's not quite how it works. These .img files we are talking about are pictures of the stock version of those paritions. Try reading this article for an explanation of Android partitioning.

There is also a great graphic here. The site is in Spanish, I haven't used Google to translate it, but the picture there is in English. Take your time with it, there's a lot of info there.

To get into Fastboot mode, do you just hold the volume down button while powering on? Never used a Nexus device before. Have been strictly on HTC up until now. I'm picking up my Nexus 4 in the morning and don't mind trying, as long as there's a way to undo anything in case something goes wrong.

Or you can enable adb and

adb reboot bootloader

The command

fastboot boot boot.img

is temporary. All it does is boot, one time only, the image you specify. Once you've mounted system as rw however, everything you do in /system before rebooting is permanent.

So does adding the su binaries and the superuser apk give you permanent root after this then?

And exactly what binaries are needed to gain root? I've never gained root using that method before so am a little unfamiliar in this territory.

Woops, wrong thread.

Yes, if you push the su binary from a superuser flashable zip to /system/bin/ and chmod 0655, plus the superuser apk, you will have permanent root after.


Also, there is a recovery.img now, so you can test that out, if it works, flash it from fastboot, then flash a superuser zip from that recovery.

 

[Harry GT-S5830]

Thank you for getting it (recovery.fstab), looks like someone beat me to it though!

Sorry for late response I have to sleep as I'm in last school year

Ill cook up a recovery just to make your efforts worthwhile

It's in OP, its probably 99.9% the same as the other guys so i'm not going to make duplicate thread, use who evers recovery you wish.

Reason I say fastboot boot first is because it allows you to boot the image without permanently (well, unless you flash another over) flashing a partition without knowing it works.

Booted fine when I ran fastboot boot boot.img, but when I actually flashed it, it's giving me a boot loop now Booting back into fastboot shows secure boot still enabled. Any suggestions? Or do you have the original bootloader image?

Not at my comp now or I'd upload it, bit of you rip open the fa Tory image from the Google servers you should find it
