try again with proper download agent (have updated attachment #36). can you flash (unmodified) stock boot.img?

open userdata_*.backup with HxD hex editor. scroll down the first 512 bytes (this is the checksum header can be ignored). after this, partition image starts. if you can see several zeros in serial, that file is unencrypted

good, in that case you can safely unlock bootloader, install TWRP and restore the backup with bckp2raw.zip. if you are not interested in sms, whatsapp etc you can also extract pictures only with bckp2win.sh (or do it manually like this)

i am not sure what happened most likely not enough disk space for creating TWRP backup. or some file is corrupt and therefore not readable.

anyway, if you are interested in extracted files only, you should copy it during halftime break.

you can exit the script with CTRL + C when you see message: "Press 'y' to unlock: [y/n]"

also see tips in troubleshooting section. you can use parameter -f to save time and continue previous session, and use -e to exclude instagram from new TWRP backup (if you think that causes error)

I pressed ctrl+c at halftime, now I have a 27gb userdata_xxxxxxxx_xxxxxx.backup file. How to open this now?

Also, I tried with a disk having 150gb free space with that 27gb file, but it again showed the same error not enough disk space

AND, I flashed the boot.img, you sent in post #36, it is still in bootloop
I tried adb with
1. Connected cable when it was turned off
2. Went to recovery mode and selected "apply update from adb"
In both the cases when I wrote ".\adb devices", nothing showed up below list of attached devices. 😓


There is an interesting part, I have another phone, exactly same model, I thought I'd try to restore those files to that phone, bot I guess it will also go in bootloop as when I did factory reset in my own device, it then functioned properly, which means the issue is somewhere in that userdata backup file only :(

the file is mounted into b2wtmp/data all files are in there b2wtmp/data/media/0

i did not modify boot.img and of course that won't fix boot loop

- you can also mount partition image manually
sudo mount <source file> <target directory>
- after mounted, type
sudo thunar <directory>
- then goto - View - Show hidden files
- you can browse files with admin rights now
- copy & paste data/media/0 to your windows disk

your apps data is in data/data/<pkgname> and can be restored with Migrate. Unfortunately it requires rooted device. If you are interested in this, unlocked bootloader is required.

Unlock bootloader method 1

- read about unlocking bootloader (sign up required)
- enable OEM unlocking in developer options
- enter fastboot mode
- get unlock token
fastboot oem get_unlock_data
- request unlock code from motorola
- unlock bootloader
fastboot oem unlock <code>

Unlock bootloader method 2

- flash the whole ROM XT1770-10_NICKLAUS_RETIN_7.1.1_NMA26.42-169_subsidy-UNLOCKED_model-INDIA_CFC_SVC from post #25. This is the unlocked version

Once your bootloader is unlocked, install TWRP from fastboot and report back
- fastboot flash recovery twrp-3.2.3-1-nicklaus.img
- Volume Up + Power to enter recovery mode

Thank you so much! I'll do that in coming days, although I just wanted some files and I was able to access them, so root isn't actually required, but still I can use the phone for other purposes after root as it's a spare one for me. Thanks anyways :)

    again, please don't use wrong scatter file, you will seriously brick your device. use that one from post #18 for nicklaus (see attachment). do a readback of stock recovery first. unpack ramdisk with AIK. this way you know if scatter file matches. only then, flash TWRP. power off device completely and make sure preloader drivers installed (should look like this in device manager)

    after successful flashing, press and keep hold Volume Up Button while disconnecting + reconnecting usb cable to PC, keep holding until you see TWRP logo

    (in case TWRP does not boot you should see something like red state - failed boot. in that case TWRP is a dead end, and your only chance left is modifying boot.img to get adb access. at this point it might necessary to flash stock recovery backup from readback back to device)

    wait, you did factory reset already? in that case crypto footer is reset too. backup is encrypted and therefore useless unless crypto-footer is restored.

    you said you restored backup, are you sure? does the phone boot into lock screen like before and is pattern still the same?

    refer to scatter file

    check your model name owens (XT1774 XT1775 XT1776) or nicklaus (XT1771 XT1772 XT1773)

    pretty much self explaining.

    why flash boot.img? are you sure that scatter matches your partition layout (you will erase wrong area if not)!?

    good, you got preloader working now! :)

    that error is different. looks like flashing is forbidden because of signature mismatch.

    read back boot + recovery first. use the files from device only (NMA26.42-169).

    after readback: try to flash that files back to device as it is. this is just to figure out if the problem is with partition signature, or with SP Flash Tool secure boot Download Agent (auth_sv5.auth file may required)
