questions about backing up phone firmware

[x000x]

I have a rooted phone with twrp installed. I've never made a firmware backup before, and I am not sure what is the best way to do it.

Ideally I would want an exact copy of the .img file, So if anything happens I could restore my phone to the previous original factory image. But I am not sure if it is possible to make a complete backup like that.

Hi

Altho I don't use TWRP but use CTR/CWM.....they are similar in that these custom recoveries (and others) offer backup of "current" firmware.

You would need to find the Official ROM for your device and flash it......except for the recovery which I assume you want to keep TWRP
Then you can reboot into TWRP and make a backup.

The backup is now a TWRP version of the original firmware.

Does that make it clearer?

2) IMHO because of upgrades, you will be better off just making TWRP backups of your current phone setup.
If you restore a made TWRP official images.....it will take you some time to do all the updates, assuming you use playstore.

good luck

problem is, i can't get it. even contacting the company was no help. thats why I was hoping to somehow pull it off my phone first... but seems like that isnt possible?

Hi

I can't see what your phone is, maybe you can add it to your signature or reply.

OK now I understand why you posted....thanks for that.

Lets pretend the only thing you did to this phone was to root it and add apps
then go into either bootloader menu then factory reset......CTR offers factory reset as well .....so hopefully TWRP will as well

otherwise
or direct into factory reset
-----some phones can only do one way.....normally vol down plus power or vol down plus camera button plus power gets some devices into factory reset mode

reset for most devices won't delete all data and root.....you should do this thru your recovery option.

Howerver........please don't do this until you have done a full TWRP backup and made a change and then confirmed you can do a full restore.

Once done.....check "installed" playstore apps and uninstall any still showing......they can be installed later from the "all apps" tab

This is about the closest you will get to official firmware without the official rom......YMMV and try at own risk.

Note that some devices can be a bit touchy in factory reset mode so you may need to redo a wipe function.

good luck

I think I might have found my factory firmware.
According to my phone, my original firmware is 139.4.6.ghost_row.ACG.en.US and one of those files that I got it from here http://motofirmware.com/files/category/9-ghost/ is ACG_XT1050_4.4.2-KXA20.16-1.31_CFC_1FF.xml.zip

But I don't know how to tell for sure if they'll be a match, but its the closes I've been able to find so far.

my model is moto x, xt1050

it looks like 442 refers to your android vesion and matches the spec page
KXA20.16-1.31 could be your build string?

see this post pls

as that user has a lot of info you may wish to post to it?

I am sure OP can offer better advice than me. good luck

Well if you just want a twrp back up of your factory firmware...make a back up of your current configuration of your device (really do this!).

Then factory reset your phone. There are many ways to do this...but it is up to you. Then go back into TWRP and make a back up of the newly reset
device. Once it is done, save that back up on your device and somewhere else...just in case. To get back to your original configuration, just use twrp
to restore the back up you made at the beginning.
