TWRP Nandroid Transfer

Just something I noticed that I am unable to transfer Nandroid backups when using MultiRom TWRP 2.6, MultiRom TWRP 2.5, or TWRP 2.6. TWRP 2.5 is the only verison that works.

I have tried fixing permission, zipping and compressing the folder, uploading to cloud, transferring over network, etc which all failed. And no, I did not encrypt the backup.

Are you running ADB as root (administrative privileges) on your computer? (run command prompt as administrator)

Yes, I know how to run as administrator. You can see that I am able to transfer with TWRP 2.5 but not with MultiRom TWRP 2.6 in the same prompt.

Have you bought it? Like from a store or something?
Have a look at this:
http://forum.gsmhosting.com/vbb/f777/full-solution-phone-disabled-ee-1959795/
Quote from article with fixes for A5:
Solution
This data is in persist partition in samsung phone named (persdata) of the phone so you need to format it to fix your phone. But to format this partition you need access to "adb shell" to communicate with phone.
1. First of all find latest CWM/PHILZTOUCH/TWRP recovery for your phone and flash it using odin.
2. Boot you phone in you custom recovery and connect the cable make sure its detected as adb device in you device manager to confirm you can also run the command in CMD ''adb device"
3. Now you are ready to format your persist partition.
adb shell
mke2fs /dev/block/platform/7824900.sdhci/by-name/persdata
dd if=/dev/zero of=/dev/block/platform/7824900.sdhci/by-name/persdata
exit
And the final step is to Wipe Dalvik & data / factory reset. Its always recommended to flash phone with other firmware then EE uk region firmware so that this will never come back.
Please note, I did not come up with this solution. I only copy and pasted it and changed the folder the persdata is in
If you have ROOT + Xposed through the app, imei changer change all your data and bypass the restrictions.

How to push files from your PC by using ADB and TWRP

Hi fellows,
I've just screwed up my leeco stock system by deleting accidentally all system files. TWRP is fortunately still working, but now I can't copy a new rom file to the internal storage, as I can't use any file explorer app.
I've tried to do this by using minimal adb fastboot 1.4.1 portable:

"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Even though I followed all the steps, It didn't work.
Any suggestions?
Thank you.

Thank you for your answer, but it didn't work for me, but thanks to that driver I could push some little files (1kb) to my mobile phone:
BUT I couldn't repeat the process with big files (like the stock rom), because the transfer gets stuck by the 1%.
The issue has been solved!
I could push the file by using Minimal ADB and Fastboot (Version 1.4.2 with installer) in recovery mode.
I needed a new computer without any old adb drivers and I used the driver suggested by bayad: https://forum.xda-developers.com/mot...-twrp-t3180926 with windows 10 in safe mode.
Thank you very much.

Guide | ADB and Fastboot | Latest

ADB and Fastboot installation guide for Windows | system wide
100% working on all windows​
Download latest ADB and Fastboot drivers, extract and replace to your existing adb and fastboot folder.
If you are installing adb and fastboot for the 1st time, follow the next steps:
1. Create a folder in C:\ , give it a desired name, (for me the adb.exe it's in: "C:\platform-tools")
2. Go to Control Panel -> System ->Advanced System Settings -> Advanced Tab -> Environmental Variables
3. Add the adb path just like in the screenshots below.

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Below, under "System variables" scroll down to the variable labeled "Path" and choose Edit and add the path of the adb.exe there too
Ok. Now you are ready to use adb and fastboot , everywhere you are. You don't have to 'cd' to the adb path anymore.
**If you ever get a bad alloc error or falling to an older adb version message in Windows 10 x64, just reboot your phone to recovery and try again.

Having fastboot installed on the PC should be enough. You sure the phone is booted to bootloader-fastboot mode (which is mandatory)? What is the response to the command: fastboot devices
