We cannot install custom roms via a safestrap right?

Not yet, maybe whenever the slots actually work

Edit: actually nvm the kernel would need to be changed and that's not possible with a locked bootloader.

When you say custom rom what are you referring too exactly. If you are running this your are running a custom rom. Its modified from its stock state so that makes it a custom rom. If there was a rom that didnt require a custom kernel in zip format you would be able to flash it in safestrap. No one seems too make anything though and I dont have time

About that, I need your help with some stuff for this on discord, max and I have no idea how to get it to work properly...

Ok maybe this evening when im done working

CRF5

Lots of people seem to have this problem it usually comes down to they are using wrong files cable or rebooting computer and trying a different port. Or the drivers or running odin as an administrator. All i can say is try all these I know it works because i have personally flashed and currently running it

Dude you have a way to modify whatever you want on this you can debloat whatever you want. I dont see why you would want to change your csc code to XAA the only thing this will accomplish is most of your advanced carrier features not working

Ok I apologize I misunderstood you. I'm still trying to figure out how to get wifi calling and volte working on the unbranded firmware, supposedly someone on here managed to do it.

Yeah it's simple, you change the mps_code.dat to XAA and leave it, do not flash stock CSC or anything.

So for example your CSC will now be XAA/ATT/XXX(original carrier)

Once you flash the BL delete cache and it makes your recovery bootloop you cant enter recovery until you flash the engbootloaders then the add cache

 

[Dayliter]

(it just reboots quickly to a logo looping fast and in a hurry) Once you flash the BL delete cache its not making my recovery bootloop ---i have tried but anyway early day tomorrow but LOL may have to leave it dl mode till off marrow or?

Just keep trying... i had same issue and eventually it worked

 

[slickrick54]

So i read through the OP again and i see this which i must have totally missed it lol.

18. In odin click rest on bottom. In CSC slot in odin flash CSC_ADD_CACHE_IMG_WIPE_DATA.tar which will do full data wipe. This must be done on first time install
CSC_ADD_CACHE_IMG_WIPE_CACHE.tar can be used to preserve data on a reinstall

Sorry for any confusion but since this newest ROM is a newer firmware can we still preserve data or does it need to be a fresh install?

As long as you have a previous version of this room you can flash and preserve data. I preserved data going from crc5 to cre9, and cre9 to crg3

 

[State.of.mind]

I am on BL V 4. Is it possible to update to V5, and then use this method to root?

Thank you i appreciate the help. I'm so out of the loop when it comes to this new way of doing it. I'm so used to the old way with twrp and regular root. Can you actually back up this stock rom with safestrap? Is safestrap only used to flash those few zips posted? Sorry for so many questions just trying to get this down
