I will try with adb tools first. Could someone confirm argedion's instructions? I don't have to worry about the block number or anything? As per this page:
http://teamw.in/project/twrp2/174
The command is: dd if=/sdcard/recoveryfilename.img of=/dev/block/mmcblk0p21
Why don't I need to use that one?
That should only replace my recovery module, right? Shouldn't affect anything else?
If my bootloader is locked, should I be able to restore the stock recovery module somehow?
If my boot loader is locked, if anyone is familiar with Safety Strap, there are a few gaps in the documentation I found:
1. Somewhere I read that installing Safestrap requires a custom ROM. Is that true, or can I use it with the stock ROM?
The description says it creates "multiple ROM slots."
2. Is that equivalent to partitioning? If my internal storage is almost full will I still be able to use this tool?
3. It says "Once a ROM-slot is active, all actions you would normally perform using TWRP are directed to that ROM-slot." So does that mean if I activate the new ROM slot and perform a backup, it will only backup the data in that ROM slot? In other words, I want to make a backup of my phone. To do that will I need to transfer everything into the new ROM slot?
4. Where can I download the APK for my phone and what other files do I need? Just the module?
