TWRP Failed to make backup folder

Today I was trying to back everything up because I needed to do a clean install. I used to have CMW, and it would work perfectly. Few days ago I switch to TWRP because of its friendly UI. Everytime I try to make a backup, I get this "Failed to make backup folder". When I go to the mount tab, or explorer, it shows my sd card and the folder named TWRP...is there any solution to this? Or should I switch back to cmw?
Thanks

If you're using the version of TWRP modified to work with SELinux (needed for KitKat 4.4.x ROMs) you may need to shorten the name of the target file before starting the backup.

Thanks a lot!! that fixed my problem. One more question: TWRP backups dont have the boot.img file in their folders. I read that it automatically flashes the boot.img when Im restoring the backup. Will it still flash it even though Im s-on?
Thanks

TWRP should backup your /boot partition to the boot.emmc.win file. As far as I know it should also be able to restore this, even if you are S-On. However, I am not positive about that

need help - how to copy TWRP nandroid backup to device?

how to copy TWRP nandroid backup to device?
I need to restore and I don't know how to copy from my hdd to the phone.
The phone is not booting but I can get to twrp recovery.

Latest TWRP has MTP mode.

but it doesn't allow me to copy one of the backup files which is: data.ext4.win000 and it's 1.5GB

You'll need to give us more information.
Why did it fail? Why did your phone stop booting?

1. flashed bigxie_hammerhead_LRX21O-signed.zip
2. flashed CF-Auto-Root-hammerhead-hammerhead-nexus5
3. booted fine but still had apps like Ti backup & TWRP not working due to root permissions
4. Went to recovery and performed Fix permission.
5. stuck in boot loop

I have had the same problem with my motox 14 the way I found around it was to copy the file to a different fold and use twrp file explore to move it to the back up folder. That has worked for me and a few others try it out it will work.

how can you copy using twrp while in recovery? are you able to access your PC from recovery?

You'll need to factory reset then reflash the ROM
Fix permissions was not required here. You need titanium beta from his twitter feed.

ok i got the phone working and lost my data but I have it backed on PC.
I just see that 10GB is used but when I browse the phone using file explorer, the device is empty.... what??

Is it a known issue?
when the phone is connected to PC I see that 10GB is used but when I i browse the device it shows as empty

No. Do a full flash of userdata.img

Please explain
What would I achieve by flashing it?

A fix for your problem. I shouldn't really need to explain that.

Thanks!
I got it working now. Only need to figure out why it shows 16GB instead of 32 and why root permissions are not working

Well the answer in the 100 other threads about space say that you must wipe data and cache.
Root should be fine, but as already mentioned, not with official titanium release.

I already did a wipe data and cache. So I don't understand why I still get this but I'll try again.
The Ti Backup link in the twitter feed is no longer valid, but for example, ES file explorer and clean master and also TWRP app are not performing as if they are rooted.
I'll try to re-install CF-Auto-Root-hammerhead-hammerhead-nexus5

ES doesn't work properly, correct. Not all apps have been updated to work with L yet either.
L is much more secure than KK. There are ways to root.
1) chain fire - makes small change in RAMdisk that allows sudaemon to work at boot
2)flash a permissive kernel - this lowers protection within selinux.
More apps work with the 2nd method, but still not all.
New titanium coming to play soon.

Root, TWRP and Flashing

I recently got an S7 (Exynos) SM-G930F and decided to root it. So I went with the typical CF-Auto-Root method... I used the latest ODIN with the correct auto root file and everything went well. I have root.
But then I noticed that I didn't have any recovery, so I installed TWRP Manager from the Play Store and flashed recovery with that. Everything works fine except for not having access to backup /Data, this was expected.
But despite everything pretty much working, I've read on a few threads here that I was supposed to wipe my phone after flashing TWRP. Now I've also read the TWRP install thread which doesn't mention anything about wiping my device, but it does offer another method of rooting the S7... Flash TWRP first using ODIN, then flash SuperSU and dm-verity/force encryption disabler.
So I have a couple of questions.
In the TWRP guides it mentions this: "By swiping right, you will trigger dm-verity, and if you don't follow the next step you will be unable to boot!". I've never had this issue, does CF-Auto-Root or SuperSU resolve this issue?
Do I need to install the dm-verity/force encryption disabler?
If I do have to wipe my device, am I going for a standard (factory reset) wipe? Advanced wipe (if so, which partitions?) or format data?
Unless there's another way to gain full access to all partitions in order to perform a complete nandroid backup (including data)?
Basically, once I've completely backed up the S7 I'd like to install the Xposed Framework. Will installing this lose any data?

Of course you are going to want to flash .zips through your Recovery, but as you have recognised there is the DM-Verification that will stop you doing so. In order to get rid of the encryption you will have to firstly have to Factory Reset but as you know this will also delete all apps and data that you have on your Internal Storage.
Then, you need to flash a .zip called 'no-verity-encryption-opt' and this will apply a patch onto your boot so you can flash unknown images and zips through.
If you can't find this no verity zip, leave me your email and I'll try and send it to you.
Good luck!
Also, installing the Xposed Framework will not cause you to lose any of your data.

Thanks for the info.
I may have already done this, I honestly can't remember. Is there any way to check if I've already installed no-verity-encryption-opt? Because I am already able to install zips in Recovery, so far I've installed a SuperSU update and AdAway. Although I do get a fair amount of 'Failed/Unable to mount /data' messages which may suggest that these zip installs didn't actually work.
I guess I still need to factory reset? And I guess that also means rooting again and installing no-verity-encryption-opt, then finally Xposed?

I had the same error message you are facing right now. Can you let me know what values you see when you view the Data, System and Cache partition, after clicking on 'Partition Options' - If you're on the latest TWRP you can take screenshots by hitting the Power and Vol Down.
^^^IGNORE^^^
No factory reset required. Basically, the file system of your Data partition is incorrect and that is why it can't be mounted on to.
Go to 'Wipe'->'Advanced Wipe'->Click on the Data box->'Partition Options'->(You may be seeing values like 0mb for most of the information displayed and why you can't mount to it; if you are not let me know!)->'Change File System'->(Try out different File Systems until you being to see true values for the sizes, but avoid using EXT2 and EXT3 if you can)
Doing all this you will be able to Mount to your Data partition, however your OS will be deleted! So get your phone into Download mode, open up Odin program on your PC, and flash a Bootloader (BL) and your phone will be fine.
Then flash the 'no-verity-encryption-opt.zip' and then your SU Binary and Xposed Framework etc.
Good luck again Buddy!

I did what you says in this post but i always have caught in ''Encrypetd phone'' or something like this.
What are the steps? 1- format data (then deletOS) and then? Can you help me please?

[H918] TWRP Flashable Stock Firmwares

with little to no activity lately for the LGV20, specifically the H918 T-Mobile variant I decided to look into creating a TWRP flashable package for the recent H91810k release. these zips flash every partition included in the latest KDZ package with the exception of recovery to keep TWRP. standard disclaimer applies, you do all of this at YOUR OWN risk! I've tested this on my device after backing up and so far so good on the latest 10k release. please report back in this thread on whether it was successful or not.
NOTE: you can find the partitions that will be flashed in the updater-script. to be extra cautious you can back up all of the partitions that will be overwritten with the following: dd if=/dev/block/bootdevice/by-name/{partition} of=/external_sd/backup/{partition}.img.
Instructions:
download H91810k.zip file listed below and put on microSD card
backup any data from internal "SD card"
boot into TWRP (requires TWRP recovery to already be installed)
create a TWRP backup of the device
flash zip from microSD card by using "Install"
flash your choice of root, either Magisk or SuperSU *Note: v12.0 of Magisk does not work with the LGV20 device in general and v11.6 is recommended.
reboot
profit!
Download:
H91810k
md5sum: ab181ec82315b656a7af48f0017f4e8c - version 1 with misc partition included (SORRY)
md5sum: 8ad07ae70c4299b3ea6e2bf747dbec1c - version 2 with misc partition removed
Flashing Process:
flash necessary partition images with the exception of recovery (to keep TWRP) from the KDZ
rename /system/recovery-from-boot.p to /system/recovery-from-boot.bak to prevent stock recovery from being installed on boot
wipes dalvik-cache and cache
BIG thanks to @McNutnut on guidance, as well as his script to put all of this together!
also thanks to @bullghost for the KDZ extractor (https://forum.xda-developers.com/showthread.php?t=2600575)
@Tilde88 for the original updater-script template w/root (https://forum.xda-developers.com/v20/development/us996-nrd90m-modded-notsostock-rom-v5-1-t3526542)

First! This is sweet!

I just tried this and it works great. I prefer to use the stock rom and to get a rooted 10k that doesn't have any known security vulnerabilities is awesome. Some notes for others:
Copy SuperSU to the external SD card and flash it after this zip in TWRP.
Make sure to select all the partitions for back up in TWRP.
On the first boot after flashing, the phone will reboot by itself. This is probably normal. You will get an "Android is upgrading..." white screen. This is expected since the cache was wiped by the script. This will take a while to complete. Even when you get back into the system, an "Android is upgrading..." message will appear in the notification bar.
Clarification: The data on /sdcard doesn't get wiped, but it's a good idea to back it up just in case. The TWRP backup of the data partition does NOT include this stuff in the backup.
I had Busybox installed before, but I didn't have to reinstall it after the flash. I'm not sure why. I assumed that wiping out system would have required me to re-install Busybox. I guess Busybox doesn't get installed on the system partition?
Adblocking using apps like AdAway need to be rerun since the hosts.txt file will be reset.
Ignore the stuff under "Process" in the OP. It's explaining what the script does. You don't have to do any of that.
The script disables the updater software. You never have to worry about the next stock release causing you trouble!

pretty sure if that's the case then YOU did something wrong... the recovery image is NOT in this package at all so TWRP is left untouched.

You did something other than flash the rom in this thread. Maybe you're confusing this thread with this one? https://forum.xda-developers.com/v20/how-to/t-mobile-lgv20-h91810k-kdz-t3618021
If that's what you flashed, you will definitely end up with stock recovery and no root.

I've tried to install this ROM but it skips through each of partition rather quickly and it never installs. I'm on H91810j with root and TWRP installed. Any ideas? Thanks.

Did you have an external MicroSD card installed in your phone? Are you using that external MicroSD card to store the files to be flashed? What version of TWRP are you using?

Yep, on microsd. TWRP 3.0.2-1

Correct, currently on 10j

Can you provide more detail on what you did? You made a pretty strong statement that you lost TWRP.
Did you follow and flash what was written by the OP? Did you do flash something else after flashing what was provided by the OP? Or did you really have TWRP the whole time?
Not looking to cause an an argument but your 2 posts in this thread have made me hesitate flashing.

Backup and Restore - a Hybrid Method (Android 9)

I am developing this method because TWRP will not restore correctly ever since I upgraded my bootloader from U2 to U4.
Boot and Data will restore but System will not, so I do the following.
Backup
1. Use TWRP to backup Boot and Data and reboot
2. Use a root explorer to copy /system/app to external sd
3. Copy /system/priv-app to external sd
Debloat by deleting apps from these 2 backup files
Restore
1. Boot into TWRP and install system.img (extract from ap section of downloaded firmware for stock) or install UPie
2. Restore Boot and Data as usual
3. Go to Advanced - File Manager
4. Delete /system/system/app and /system/system/priv-app
5. Copy and paste backup app files to /system/system
6. Reboot
Note: TWRP has its own system which holds the ROM system as a sub directory.

If anyone can think of another system directory which I can backup and restore please let me know.

This is great. I have issues that caused my settings app to show extra and weird options after a restore from TWRP in the past. But since then I've updated to a new TWRP but haven't done any restoring because of what the previous one did. Hope this works when I need it to.

Not sure.
If it doesn't work it might reboot into recovery and then you need to copy and paste your own /app and /priv-app folders back in place.

@physwizz My appetite for being screwed by Samsung and the dirty traps they lay is severely diminished. Since going to U4, I can't reliably get TWRP to work without triggering the evil red text screen of death.... I have been watching what is happening with the work on custom kernels and Ultimate Pie ROMs but definitive information on what is actually working reliably or not is very patchy..... one person will say "Yep, this definitely works" the other will say "nope can't even boot"... almost like some people don't even own this phone or have not actually tried what they are promoting or are unable to follow instructions properly....
So....starting from stock U4, I can root and install TWRP, magisk and dmverity no problems at all but after going back into the O.S and attempting to reboot into recovery a 2nd time....bang! Samsung screws me!!!! The question is.....is there a custom kernel for U4 and above that truly removes all of Samsung's dirty tricks (security features) and a custom ROM that also holds no hidden surprises?

If you're talking about the red text that talks about 'official binaries' when booting after you flash TWRP (FRP LOCK) then there's a very easy fix.

@physwizz Yes the evil red text...but it is not after flashing TWRP, it is only if you try to go back into TWRP.
I already know of one easy fix... called don't buy Samsung. All this wouldn't be a problem if manufacturers could resist the temptation to "monetize" private data but that ain't going to happen anytime soon in this dog eat dog world.....

I got that because i was using old data
solved by doing a clean install
The data was then good in future

@physwizz Went through the Samsung dance from scratch, installed UltimatePie4, rebooted into Ultimate Pie no problems, completed the initial setup.....rebooted and back to red text of death!!!
Yes, I did all the format /data etc.... it is not a procedural problem on my part but my phone has always given me more grief than you appear to have - something is different

@physwizz Did nothing but complete the initial setup after install and rebooted.....all started from a clean install of U4, then rooted and TWRP from your tar file, then installed new ROM with data freshly formatted i.e. absolutely no messing around with the stock ROM or custom ROM through the entire process and never getting to the point of rebooting into TWRP which triggered the previous red text of death.....
