Backup from fastboot? - OnePlus 6 Questions & Answers

I recently messed up my phone. and stuck in fastboot mode.
Before I started working with the roms , etc I ended up backing up a nandroid in TWRP , as well as a full TB backup.
I also did a full Google backup as well.
now the problem is that all the nandroid backup and TB is on the internal SD card.
Can get into the phone via PC and it is unlocked.
Is there any way to get data off the internal SD so I can easily restore my information once I unbrick my phone ?
Thank you,

G1 bootlooping lost nandroid backup

My phone is stuck on the android screen after apps to sd. Like an idiot, i lost my nandroid backups. So, im stuck. Any ideas? Thanks in advance for any help.
have you tried doing a Alt+W? wipe?
I cant even get that far, i can only get into the dev boot loader. (androids on skateboards).
Solved. Was able to recover images from reformatted sd. Thanks

[Q] Recovering data after a wipe

I've unlocked the bootloader on a HTC Desire 510. This triggered a wipe. Afterwards, I wiped the system using the recovery. I had some photos on the internal SD card that I need to recover ASAP. Currently, the phone doesn't have any ROM, and I can only access it through fastboot and adb (adb in Phillz recovery). I've tried pulling the images from /sdcard/DCIM, but it doesn't pull anything, saying that no files are there.
I'm thinking of running photorec on the phone, but since it's the internal SD card, I can't mount it to the PC from the recovery. I thought of putting a ROM .zip on an sdcard and flash it, but I'm afraid that a flash would make recovery impossible. Is there a way I can dump the internal sdcard image just through fastboot and adb? Any ideas would also be most welcome.

flashing a new ROM.zip will only delete everything for sure.
I'm sory to say it, but by my knowledge there's only one way to recover them, and that's by recovering a backup on recovery mode.
I hope you did make a backup before unlocking your bootloader. If you didn't, I think there's not very much you can do :s
anyway, please remember to ALWAYS make a recovery backup before doing anything in recovery.

What kind of backup??
For a nadroid backup you need a custom recovery, and to flash a custom recovery you need a unlocked bootloader...

Yes, AFTER I unlocked the bootloader. There were all in all two wipes, although the second one was only /data and /cache.
I did a backup using adb, but to my knowledge, that's only a backup of the apps and their data.
When you unlock a bootloader phone, you lose everything, including photos, musics, etc.
Do you have a backup of your files?
Sorry bad english
If I were you, I would restore the backup with adb and see if you have your photo's back.
Otherwise I have no idea for how you can restore them sory...

Why does nobody read my OP? I said the phone doesn't currently have a ROM on it. I can't restore that backup.
I'm going to flash busybox, a 300kb zip file that probably won't overwrite too much data, and use dd to get what I need.
If you have an adb backup of your files in the pc, you can extract it and get your photos back

Honor 6x messed up, need a twrp backup please! BLN-L21

Hello!
The Ota Update messed up my unlocked and rooted 6x It tried to flash itselfe with TWRP
The Phone doesn`t boot anymore, but TWRP is still working.:good: sadly my Internal Memory is corrupted: I can see the Name of my Backup, but it is "unreadable". i tried to put it on my PC... i ended up with an empty folder. Oh and yeah i didn`t backup my backup, i have the Phone just one Week now. so before i start fastboot flashing, can someone of you give me a TWRP Backup? Thank you!
To do so: Go to TWRP make a Backup. Now wipe Data,Cache, Dalvick and internal storage. Make another Backup. Please give me this "clean" Backup. Then you restore your first Backup and anything is back to normal
*Edit*
Ok my Phone is Back to Life
I used the Unbrick in the Honor multitool

Need Help to restore backup with TWRP

Can anybody help?
My HTC U11 still run on Nougat.
Yesterday I want to update with the newer version of Nougat (Not Oreo)
I already make a data backup with TWRP, big backup 22Gb.
Then I update the new stock Rom from PC, it had no problem.
Go to download mode, and then install TWRP again with ADB from PC.
Go to TWRP Recovery, it still works.
The last thing I do is to try to restore the 22Gb data back to my phone.
And it always get error on 9% with "extractTarFork() process ended with ERROR: 255"
I already change with difference TWRP from 3.1.1.0 to 3.2.3.0, still the same.
Restore to previous version of Nougat with TWRP (system, system image, boot image, recovery). Try to restore backup data again with no luck.
Try to check MD5 with the backup data, and it said matched, no corrupt.
Already try searching in the web, but with no solution too.
Do anyone ever have the same problem and solved it?

I have 2 backup. One is for system and one is data. I can restore system feom TWRP recovery, but can't restore data
After restore system,reboot to twrp and restore data
I had this problem and it took me two days to resolve it. I had a good backup and I know it was good because I had used it several times and it worked. But then after doing some system installs I got the error 255 when I tried to restore it. I tried several things to fix it and nothing worked and I really did not want to lose my backup. What did work for me was to use TWRP wipe function to FORMAT the phone. Wiping or factory reset did not work. I lost the contents of my internal SD card but I was able to transfer most to my external SD card. You could also connect the phone with a cable to a computer and use the pull command in ADB to backup the contents f the internal SD card. Given the choice between losing the SD card and the data files I come to lose some of the SD card. Anyway, a FORMAT worked when nothing else did. I read that this error is caused by a lack of space. When I checked the log it seemed that the restore was failing with a particular file which misled me to thinking I had to remove the corrupt file, but since after the format I was able to restore without any problem, it would seem that there was no corrupt data. Hope this helps someone.

What's up with the TWRP backups restore

Hi guys,
I've been using TWRP on nearly all my devices and never had problems doing nandroid backups and restores.
Well today, I've been to a near-hard brick and barely managed to get back to boot after I attempted to restore a backup.
My steps:
1. Backup all partitions available
2. Restore those
After that I end up in the bootloader and couldn't boot into anything. Anyway, I solved it but want to know:
Did I do something wrong? What would be the correct steps and/or partitions to backup and restore?
Thanks

I did the same thing and ended up in a worse problem. It would not even go into recovery or be recognized by the computer. Gave me a near heart attack and took several hours and some luck to read the right article to recover. I think one has to only save and restore system, vendor, boot and data. One article on TWRP website has recommended that one should only save system image and vendor image and restore them. What would happen to the data partition then? I am not willing to try again unless someone can give a step by step description for fear of hard bricking my Pixel 2.
