Hello,
I have a rooted, unlocked XT926 Motorola Droid Razr Maxx HD on [4.4.2] 183.46.10. I have installed a custom recovery (TWRP) though I don’t really use it for much because I don’t install custom ROMs. Now I need to do something, though, because my OS has some corruption. I’d like to do the minimum possible to deal with the corruption. So I’m thinking either flash the same version [4.4.2] 183.46.10 fxz, or go up to .15.
Best case scenario, I’d prefer to still have root and still be unlocked and with TWRP when I’m through, but also still have my data. [Though yes, it’s backed up in case I lose it.]
I don’t play around with this too often, though, so I’d like to confirm that my assumptions/conclusions from my reading are correct. My thought/plan was to use RSD Flasher and go to either .10 or .15 using the Keep Data option. Will this work, and will I still have an unlocked bootloader with TWRP so that I can re-flash root? Or is there a better/different way to do this?
I got to this proposed solution through the following thought process... which is why I am questioning my plan.
1. If I use SamuriHL’s RSD Flasher, it looks like I can flash .10 or .15 and keep my data by using either the “Keep data” or the “Universal” option. But if I use TWRP to flash .10 or .15 my data will go away? Is this correct?
As a side note, can anyone point me at an explanation for the relevance of keeping GPT and TZ (Universal option) or make a recommendation about using this option over “Keep data”? Given that I’m dealing with what I believe/hope to be corruption in the OS, I’d rather get rid of as much as possible without losing my data, which sounds like “Keep Data”.
2. I am slightly confused about information telling me that if I unlock my bootloader I don’t need to worry about root exploits anymore, vs. information telling me that if I flash stock fxz’s such as the ones from drdevs (it won't let me post the link, sorry) I end up back at, well, stock… plus I’m talking about the possibility of using the RSD Flasher method rather TWRP to do this. If I use the RSD Flasher to go to .10 or .15, will I lose my TWRP/ will my bootloader re-lock? If I stay unlocked and with TWRP I assume I can then use it to re-flash root once I have completed the ROM fix. OTOH if I am relocked I assume I need to stay with .10, not .15, and re-unlock the bootloader…
Thanks in advance, dlc
