[RECOVERY+LOKI][CWM][MDK][VZW] SCH-I545 CWM v1.0

DISCLAIMER:
Your device, your responsibility. I am not liable for anything you flash, including this.
As a result you'll probably want to read the rest of the thread and at least be aware of what you're flashing.
You've been warned.

CM: CWM Based Recovery for SCH-I545 (jfltevzw)

Features:
This is comes from CM as it is provided in the source repos. I will be keeping it as such at this time.
If modifications deviate from CM source we will set up a new repo.
The recovery image has already been patched using the Loki method.
This also means it is tied to MDK signature and should only be flashed on MDK.

Screenshots: None

Latest Build: v1.1
Tar/ZIP Mirror: [CWM][RECOVERY]Team SXTP CWM for Galaxy S4 (Team SXTP Site)

Flash Instructions - READ THESE CAREFULLY!!!
1) Download Zip
2) Unpack Zip and place items on your phone. Assumes you're doing commands from folder where files were extracted to.
For the sake of testing let's say /data/local/tmp like djrbliss used. (ADB push was used in that example)

Code:

adb push recovery.lok /data/local/tmp/
adb push loki_flash /data/local/tmp/

3) Go to ADB shell, su and flash using following commands: (assumes path is /data/local/tmp for Step 2)

Code:

adb shell
su
chmod 755 /data/local/tmp/loki_flash
/data/local/tmp/loki_flash recovery /data/local/tmp/recovery.lok

If successful you should see something similar to:

Code:

[+] Loki validation passed, flashing image.
2253+1 records in
2253+1 records out
9230848 bytes transferred in 0.656 secs (14071414 bytes/sec)
[+] Loki flashing complete!

Assuming you see the above, you should be ready to boot to recovery.

If you do not see this you should immediately flash the stock recovery by dd.
If you don't know how to do that, stop, ask for help. Let's try not to brick a phone doing this, okay?

Summary Changelog:

Code:

v1.1 - Correct typo on device name (in CM device tree).  Repo was still okay.
v1.0 - Initial based on Sprint progress (jf series shares same fstab)

Source:
CyanogenMod Official Repositories
Device Dependencies:
android_device_samsung_jf-common
android_device_samsung_msm8960-common
android_device_samsung_qcom-common
Verizon GS4 Device Repository

NOTE: Due to potential copyright issues I do not include a vendor repo.
You can extract the files from the phone or ROM as needed - should you decide to build on your own.

OP has been updated with a Loki patched recovery image and flash instructions.

If you run into problems, STOP and post here with the issue.
Let's do this as safely as possible until we confirm some safe flashes.

garwynn · May 23, 2013

Again, asking that anyone who flashes this post their results. Obviously a lot of folks watching and although it shouldn't be an issue everyone likes to wait for first outside validation before flashing.

If it helps at all, I used the same process for the most part. It does indeed work.

1|shell@android:/ # /data/local/tmp/loki_flash recovery /data/local/tmp/twrp.lok
covery /data/local/tmp/twrp.lok <
[+] Loki validation passed, flashing image.
2559+1 records in
2559+1 records out
10484224 bytes transferred in 0.713 secs (14704381 bytes/sec)
[+] Loki flashing complete!

only difference is I used TWRP

im losing my damn mind. someone care to explain this?

Code:

root@android:/sdcard # /sdcard/loki_flash recovery /sdcard/twrp.lok
/sdcard/loki_flash recovery /sdcard/twrp.lok
sh: /adcard/loki_flash: not found
127|root@android:/sdcard #

i get this after a chmod of loki_flash. if i dont do chmod on it it says it cannot find the file loki_flash.....wtf?

Code:

root@android:/sdcard # /sdcard/loki_flash recovery /sdcard/twrp.lok
/sdcard/loki_flash recovery /sdcard/twrp.lok
sh: /sdcard/loki_flash: can't execute: Permission denied

I tried just renaming the .img file to .lok, but it gave me a few errors. So using djrbliss's Loki tool (much thanks!) I generated a file for the TWRP recovery.

Here is the link: twrp.lok - 10.00 MB

You have to put the files in a folder like /data/local/tmp since the sdcard folder does not allow executables contrary to the instructions provided. (At least that was my understanding when trying to debug the same issue!)

I get a successful flash but still only get stock android recovery. I think it is because I can't find the install reovery.sh to delete it

It's in /system/etc.

joshw0000 · May 23, 2013

I think I read in the other thread, they had success doing this on the pre-release kernal.

not on my S4 it isn't lol. I get the successful flash, reboot to recovery, get stock recovery, reboot system from there and I then get the Samsung logo with the unlocked padlocked telling me SOMEthing unnoficiall got installed. Phone boots up and I boot back into recovery, still stock recovery, reboot system again and I get normal boot up, no padlock screen. I'm still on the mdk kernel so I will try flashing the pre-release kernel a little later and trying again.

joshw0000 · May 23, 2013

I see a recovery-resource.dat in /system/etc but not recovery.sh.

You can use GooManager and install Twrp... Just have root first.

Have you done this? I tried it on a (locked bootloader) Note 2 and got the screen that I needed to take the phone to a Verizon store. It took me an hour or more to fix it.

I tried that and got the "You have installed unofficial blah blah contact Verizon" message. I had to generate a TWRP loki image and flash using the OP's instructions.

NxtGenCowboy · May 23, 2013

It works fine. Make sure you are rooted.
