Installing and using Safestrap 3.75 (2015)

[sd_shadow]

Because of the Locked Bootloader, the Stock Recovery cannot be replaced.
Safestrap Hijacks the boot process allowing for a custom recovery (TWRP)
In this custom recovery, Custom Roms can be installed, along with other functions that a custom recovery allows.

17 Aug 2015: Currently the newest version is Safestrap 3.75
Cm12 requires safestrap v3.75 (or newer)
3.75 is compatible with older roms.

Rom Slots are created in Internal Storage/Internal SD Card
In Twrp
Select Boot Options
Select a Rom Slot (1-4)
Select Partition Sizes
Sizes depend on Rom, Gapps, other Apps...
Partition Sizes cannot be changed again without deleting Rom slot.
Start with System: 700MB Data: 2000MB Cache: 10MB (For Lolipop)
Selected Space cannot be larger than Free Space
Select Create Rom Slot
This will take Several minutes

Don't worry screen time just timed out, tap touch screen to wake.

[sd_shadow]

If you are Installing on Stock Slot, Backup Stock Rom first

Download Rom/Gapps
Verify Roms MD5 with a Checksum Utility

Installing a Rom
Make sure the Rom Slot you want is selected (see 2nd line from top of Twrp Screen)
Select Wipe>Advanced Wipe>Check Dalvik Cache, Android Secure, Data, Cache, System
Swipe to Wipe
Home screen
Select Install
Select Storage option Internal or External SD card that rom zip is on.
Check Storage Option (Internal storage or External SD Card)
Ok
Browse to file and select
Swipe to Confirm Flash
Should take a min or 2 to install, watch for errors
if you see any errors, rom may not boot correct
it may not say successful or complete
when you see Wipe Cache/Dalvik and Reboot options it's done.
Select Wipe Cache
Swipe to wipe
Select Back
Select Reboot
Rom should should boot within 10 mins, if it doesn't something's wrong.

Many Custom roms don't include Google Apps/GApps (playstore...)
Sometimes Dev posts a link to preferred GApps version.
For the XT910/XT912 I suggest installing a Minimal Gapps because of the smaller System size and lower memory compared to newer devices, like pa_gapps-modular-nano...

Be sure to install a GApps Version that matched Android version of Custom Rom.
See sd_shadow's Collection of GApps Links

Install Gapps zip after installing rom
using same steps (do not wipe data)

Changing which rom slot boots
In twrp
Tap Boot Options
Tap the rom slot you want to boot
Tab Activate
Tab Home
Tab Reboot
Tap System

 

[sd_shadow]

if you have a XT912 or XT894, There is a Modified Safestrap 3.75 for unused partitions (/preinstall & /webtop) by Mentor.37
Safe Slot uses
/preinstall (~ 600mb) for /system
/webtop (~ 1,4gb) for /data
/cache is shared with the Stock Rom slot

• Safestrap-maserati-v3.75-unused-partitions.apk
• Safestrap-spyder-v3.75-unused-partitions.apk

Using Safe Slot
Same as other slots but must also install flashable ramdisk for not stock based roms cm11, cm12...
Ram Disk for XT912/XT894
CM 12.1: ramdisk-update.zip
CM 11: cm11's_ramdisk_for_safestrap_for_unused_partitions..zip

Note: Mentor.37 has removed the Safestrap splash screen, so you must select reboot to recovery from rom or Boot to safestrap from Stock Boot Mode Selection Menu

I have a small problem on my spyder, I am using SS by Mentor.37 and safe slot have problems in the system partition, it has 605MB and without having anything installed any ROM shows 0 free, I looked for the solution on the official topic of the SS and saw to fix the problem we have to format system (in safe slot) using a different file system, but it did not help. okay i restored the system with RSD and the whole process and such ... the slot safe was okay, but if you try to format the system to try another ROM he gets in trouble again! Is there any solution?

Trying to learn but stuck....

Hi, I have a Verizon RAZR XT912 at Android 4.1.2. I am new and trying to learn how to do this so forgive my ignorance. My TWRP program has no "Boot Option". The main screen has (Install, Backup, Restore, TWRP Install, Settings, Reboot, Support, About). I have done back-up and it took a few times before it seemed to go into a backup mode and it said it created a backup. I tried to install CM12 and found it in my "SDcard1" , then selected the .zip file by checking the box. Then I got the warning "are you sure you want to reboot to recovery and complete the specified actions?" I click OK but nothing ever happens. It took Kingroot several attempt to finally root the phone but RootCheck says it is rooted. I am kind of lost because the apps are not working the way I have been reading and even the program screen shots are different than what I am seeing.

Is it possible to create/edit/mod SafeStrap 3.75 (for XT910) without splashscreen during the boot (like in xt912 by mentor)?

 

[majamee]

@sd_shadow Do you see any possibility to update safestrap to use the freshly introduced TWRP 3.0 sources?

Hi,
The image files from the safestrap rom slot folders ... viz ... cache, system and userdata .img files are as good as the twrp rom backup files ?

further merely replacing this old userdata.img into a freshly setup rom slot will work just as good ?
I have backed up my kitkat virtual ROM slot folder, and i am setting up a lollipop ROM anew, would be great if i could just replace the new userdata.img with the one i have saved from my previous kitkat ROM.

thanks,

I've followed the instructions on rooting and installing SafeStrap. But I can't find a definite answer as to why I can't create a slot. It shows 0 space available. Would you know what to do? Thanks
