[CWM][EXPERIMENTAL] Samsung Galaxy Express 2 SM-G3815

aureljared · Jan 5, 2014

I do not own this device, rather I own a Galaxy Express 1. This thread was created to see if the image boots up.

Terminal way
recovery.img
Do this from a terminal:

Code:

su
dd if=/path/to/the/recovery.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery

Odin way (Will trip KNOX)
recovery-cwm-6.0.4.5-wilcoxlte.tar
Uncheck Reboot and F. Reset, flash through Odin.
Press Vol Up + Home + Power to boot into recovery.

Yes, CWM will detect absence of root on reboot and prompt you to add it.

I think there is a script inside /system/etc named install-recovery.sh which is responsible for that.

One more thing, are you sure you unchecked reboot in Odin? And booted up directly to recovery after flashing?

Gosh, everything's hard without root.

CWM build recipe

Terminal way (you can't do this yet, you don't have root as of 1/5/2014)
recovery.img
Do this from a terminal:

Code:

su dd if=/path/to/the/recovery.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery

Odin way (Will trip KNOX)
recovery-cwm-6.0.4.5-wilcoxlte.tar
Uncheck Reboot and F. Reset, flash through Odin.
Press Vol Up + Home + Power to boot into recovery.

Please report your findings in this thread.

Hi aureljared

Thanks for helping the SM-G3815 community to have CWM.

I assume you once built CWM for Express 1

I tried myself to build one as follows (where /tmp/recovery.img is stock):
--
mkdir sm-g3815
cd sm-g3815
export PATH=~/bin:$PATH
repo init -u git://github.com/CyanogenMod/android.git -b cm-11.0
repo sync
. build/envsetup.sh
make -j8 otatools
export PATH=$PATH:$PWD/out/host/linux-x86/bin
build/tools/device/mkvendor.sh samsung wilcoxlte /tmp/recovery.img
lunch cm_wilcoxlte-eng
. build/tools/device/makerecoveries.sh cm_wilcoxlte-eng
--

But if I copy it to partition with dd and reboot into recovery, device will vibrate a few times and boot normal.

Maybe for Samsung Galaxy one needs some special recipe?

Which one did you use?

Thanks

Hi aureljared

Having root I thougt, let me try:
I copied as follows your recovery partition (as I did with all candidates)
# dd if=recovery.img of=/dev/block/mmcblk0p14 bs=2048

As terminal23 mentioned, one boots into something that appears to be stock recovery binary.
really odd indeed: one just overwrote stock recovery partition and now one see it again!
Note that my own built CWM recovery.img does appear to not run any visible program, vibrates a few times and boots as normal phone.

I have restored stock recovery.img with same command.

How does your CWM build recipe look like?

Thanks

I did not build this, I simply repackaged ramdisk with your kernel.

Thanks

Yes, seeing that they have close specs.
I wanted to try the ramdisk from the S4 mini but since this one doesn't even boot, I didn't bother.
