Need to flash a TWRP backup with fastboot - General Questions and Answers

Hi. I have to flash a TWRP backup and can't do it thorugh custom recovery due I have a Yotaphone (the phone with a LCD screen by one side and a eInk screen by the other side) and the LCD screen is broken, so I have to use fastboot or adb (as far I know). I cannot even install a ROM because it needs the LCD screen for the first start.
The question if I can do it, cause I know it could be problems with formats.
(I asked this on Yotaphone specific xda forum but no one answered)
Thanks

You would probably have better luck flashing the stock firmware or have someone with the same device create an adb backup then restore it via adb.
Or if you know which individual .img files you need, have them pull a copy of whichever individual .img files you need(for example: system, boot, etc) then fastboot flash them or use adb shell to dd the .imgs back onto your device in the partitions they belong in.

@Droidriven ,you are right about it would be easy to fash a stock rom, but the LCD screen is necessary for that due the first boot. Maybe I am a little lucky 'cause I live with person who has the same device as me.
I tried the adb backup -all but it seems to just make a backup of the personal data.
Making a dd backup patition would be the better, but for some reason my device isn't recognized as a MTP device and can only connect in PTP. Tried to change the configuration on the phone but still only works with PTP, and I think in PTP mode doesn't have a mounted folder where I can make this stuff.
What I don't know how to do is the dd within the adb shell. It will work connected in PTP mode?

Is USB debugging enabled?
I DO NOT PROVIDE HELP IN PM, KEEP IT IN THE THREADS WHERE EVERYONE CAN SHARE

Yes, debuggind mode is on. In PTP mode, adb sees my device correctly, in MTP mode appears like ???????

I think maybe the answer is where that you mentioned about "adb shell". As long as I can't see the phone mounted in MTP mode it's the only way I see. Now I am searching for the way on pointing the dd output file outside the adb shell. So the process is:
BACKUP:
-adb shell > dd partitions saving them outside the phone
FLASHING:
-fastboot partition by partition
Another problem I have is to know which partion is each, 'cause with "mount" I don't get so much information and with "cat /proc/partitions" only have 13 partitions with their size and no more info. I am looking what to "adb push" that can help me. Maybe install busybox.
Trying to backup&restore without MTP, without access to the recovery nor SDcard... Harder is impossible!!!

This command in adb shell or Terminal Emulator should give you your partitions and names(obviously you'd type "su" then press enter then run this command)
ls -l /dev/block/platform/msm_sdcc.1/by-name/
The part with "msm.sdcc.1" might be different for your device. If that command doesn't work I'll help you find what needs to go in that part of the command for your device.
I DO NOT PROVIDE HELP IN PM, KEEP IT IN THE THREADS WHERE EVERYONE CAN SHARE

su is not found inside the adb shell, and I found this is cause is not rooted. I have to do it through TWRP in android 6.
As I said, I have two devices of my model so I hope I find time tomorrow for doing it. I also hope to can flashing it to the other device in fastboot mode or some way it doesn't need the main screen (remember I have a LCD screen and a eInk)
I will say something when I do the root. Thanks

Finally did it!
It appears each partitions clearly with the "ls" command you give to me. The question now is how to dd outside the phone. Have I to mount the pc inside the shell or what?

adb shell should work to dd, you just need to make absolutely certain that you are dd-ing the correct .img to the correct partition(mmcblk0xx), the partition number would go where the xx is.
For example, my recovery.img would be flashed to mmcblk018(the number of my recovery partition.
If you dd an .img to the wrong partition, you'll brick the device, the command has to be exactly correct, no margin for error or easy fix if you get it wrong.
I DO NOT PROVIDE HELP IN PM, KEEP IT IN THE THREADS WHERE EVERYONE CAN SHARE

I know all this stuff, but first I need to make the .img of each partition, and I though with adb shell I could do a dd to outside the phone. The TWRP backup I have isn't .img files, they are .win files.
I searched again if its possible to do that and all I found is the xda thread about doing a workaround with adb forward and busybox. If there is no more options I will do that.
What I thought to do is create a backup of the needed partitions and save them in the userdata free space. I think this have to be possible, but as I cannot use the LCD screen I have to do the backup where I do not have to pass thorugh the first boot configuration, cause it is did in the LCD screen. Which partitions have I to backup? Only system and boot? Or there is another tool for creating .img backups?
EDIT: Also found the twrp adb possibilities (http://www.pocketables.com/2014/10/using-twrps-new-adb-interface.html) but have the same problems than with dd

I frequently modify boot and recovery partitions from within terminal app. Here's what I do to grab the boot partition for example(you likely want BusyBox installed first)
cat /dev/block/bootdevice/by-name/boot >boot.img
or
dd if=/dev/block/bootdevice/by-name/boot of=boot.img
Make changes, then reverse the commands to write back. I think cat gives you a more verbatim copy for initially cloning a partition. I have had success with both.
The question that brought me here is what happens if i flash all partitions from a firmware archive and attempt to upgrade a whole system this way from twrp recovery.....

[Q] Bricked Note. No Samsung Logo

hi all,
So, I've been a bit of a idiot.
In a nut shell I was trying to manually remove the flash count and followed the wrong tut.
I did dd if=/dev/zero of=/dev/block/mmcblk0 bs=1 count=1 seek=3145732 and now when i try to boot the note I dont get the Samsung logo splash screen, I get a screen full of static.
I can access the recovery partition, I can also access in download mode with odin.
If I try to flash the stock rom, it completes ok but doesn't auto restart and stays on the odin mode screen.
I do get E:\ unable to mount /efs when i wipe the cache's.
I have a 2nd note 10.1 (both n8010) so I'm hoping I can fix/copy/image from the 2nd working device.
Any ideas on how to fix? or is it now an expensive paper weight?
I have flashed the stock firmware and rom from samsung-mobile but no joy.
thanks,

You are in a tough situation my friend
I think as long as the recovery and odin work there is a chance...
can you give me the link to that tutorial .. I think i may help
Or do you remember where that sector was??
Anyways you may try to backup both devices EFS (backup that of the non working device in case you need it for anything) .... (But i think the EFSPro wont work) (you may do that using EFSpro or i think it may be done through the shell by "dd if=dev/block/mmcblk0p? of=/sdcard/efs.img" where "?" is the number of EFS partition you can know that from shell command mount "i think its mmcblk0p3") .... then restore the EFS of the working device to the non-working one (EFS pro or using "dd if=/sdcard/efs.img of=/dev/block/mmcblk0p?" "i think its mmcblk0p3")
I hope this would succeed although i red that it contains MAC address data which may prevent both devices connecting to same network
(N8010 has no connection to cellular networks so i think no problem)

But before all these go to shell and try "dd if=/dev/block/mmcblk0p3 of=/sdcard/efs.img" and "tar -cvf /sdcard/EFS.tar /dev/block/mmcblk0p3"
if these commands succeed you would have a backup of old efs before changing any thing (keep it in a safe place)
Look you may try just backing up and then restoring the same EFS of the device
Try this first: use the tar command to copy the files of EFS "tar -cvf /sdcard/EFS.tar /dev/block/mmcblk0p3"
then do " mke2fs /dev/block/mmcblk0p3" the last thing is to restore the tar with "tar -xvzf /sdcard/EFS.tar -C /dev/block/mmcblk0p3"
I prefer you try what i said first as it's shorter and makes nearly the same thing except that it takes all files not just the nv_data.bin
You can then try that tutorial in the link i think it works and you can get the that file nv_data.bin from your other device or from the non-functioning one if you can extract it from the tar backup in the first step
Cheers for the replies guys.
I'll find the tut I followed and post a link.
I'll also look into the link and suggestions you've mentioned.
My main issue seems to be that I can't get a adb connection to the device as it won't boot.
Even with cwm 6.1 installed, I still can't connect. Bear in mind, I've flashed back to stock but not been able to boot it to put it into usb debugging mode. does this mean I'll never be able to get a shell open?
I have managed to create a efs.img from the working device but have no way to push to the broken one.
Any suggestions?
Thanks

You say that adb wont work even from CWM??
Try this and see if it works http://www.dominantwire.com/2012/11/how-to-solve-adb-device-not-found-error.html
yep, even when booted into cwm recovery i still can;t connect to adb
just downloading a custom rom now to see if it's the stock rom causing the issue.
although I am able to access adb in cmw recovery from the other working device, even with USB debugging turned off.
sadly that link is no good.
I'm able to connect to the working device on the same cwm recovery version, using the same cable, so setup and PC are ok.
I dont know if the roms are the same (maybe not) but I'll flash the broken one with a custom 'pre rooted' rom in case it helps.

Ok try another rom as i think roms have diferences in adb !!
if not working also and If you know you can safely flash a new recovery .. try TWRP it has an inbuilt shell .. the keyboard is not that good but you can try it better than nothing
ok so....
I've flashed an different custom rom via cwm install from ext_sdcard. After a reboot I now have the samsung logo back!!!!
It's hung on the samsung logo for a wile now, 5 minutes or so, but I'll let it sit there for a good 30 minutes to be sure.
I'll see what happens from this rom flash, but failing this I'll stick TRWP on and have a go with the inbuilt shell. even if i can mount ext sd I should be able to restore the block i over wrote.
getting closer!!!
thanks so far,

Good to hear .. i hope it finishes the problem .. but in case it fails before flashing TWRP try from adb .. adb kill-server then adb start-server and adb usb and see if it works
will do, thanks.
I've just noticed that the command i ran I outputted to mmcblk0 and your commands refer to mmcblk0p3.
Am i right in guessing the the 0 part lists the disk and the px part is referring to the partition on that disk (so to speak)?
so my original command which broke it basically wiped the internal storage? this would explain a lot about failed connections as well.

Did the device work or did you manage to get adb connection??
Anyways ... from what i read during searching is that if=/dev/zero and bs=1 count=1 seek=3145732 parts of your command writes zeros only to one byte, one time after seeking 3145732 blocks of the storage which seems to be in EFS partition which says cant mount ... So the commands i wrote are to take a backup of whatever files in there then format the drive and restore the files back to it ... after formating using mke2fs reboot the device before restore and see if it shows the cant mount message again
arh ok, that makes sense.
I've managed to tar the efs files form the working device.
I then opened the shell in twrp and did a mke2fs /dev/block/mmcblk0p3 which completed ok.
But when i try to tar -xvzf EFS.tar -C /dev/block/mmcblk0p3 (from the external sd dir, it tells me that the mmcblk0p3 isn;t a directory.
any ideas?
thanks again
how about doing a dd if=efs.img of=/dev/block/mmcblk0p3??
I got a efs.img from efs pro on the working device..

try remove -C from the command it's for directory my mistake
and you can also try dd with (if=/"path of extsd"/EFS.img) but try the tar first .... after that see if it tells you cant't mount EFS by opening mount and select EFS and see if it becomes with an 'x' then going to the upper right corner of the screen and pressing the icon beside back and home and see if it shows cant mount EFS
sorry, before you replied i went and did a dd if=efs.img of=/dev/block/mmcblk0p3
I then flashed the stock ROM and BOOM!! im in!!
YEAH BABY!!!
only issue now is that the boot loader isn't quite right.
1 - it doesn't show the 'Samsung Galaxy Note 10.1" splash screen
2 - instead of above I get a screen showing the last thing i was doing, ie, download mode, but with static across it.
any ideas on how to correct this?

Can you answer some questions??
what do you mean by you are in?? .. can you get to android or not yet?? ... what do you mean with getting download mode with static ??
would you try going to recovery and clear cache and dalvik cache to try??
sorry, by I'm in I mean that I can now boot to Android.
when i say download mode with static, image the download screen but fuzzy and punctuated with white nose.
I've done a cache format and a reset to factory but I still get the same issue.
Also, I'm still unable to get an adb connection to the device.
I have noticed that the serial number has now changed to the same as the working device but thats expected as we copied the efs contents from one to the other.
thanks for all your help. you saved my bacon

Is there a way to delete/uninstall an APK and its data from fastboot?

so i went into FKU franco kernel updater and changed my CPU max speed from 1500 back to the default but did not change my voltage settings back to default. now the device is softbrocked and just boots to the google nexus splash screen
I have tried flashing:
system.img
boot.img
bootloader.img
stock 4.4.4 kernel
yet regardless of flashing the above the device still is softbricked and wont get past the nexus google logo.
the only thing i have not flashed over is my user data and thats because i dont want to lose my pictures and video of my little boy that i didn't get to back up yet due to my dropbox just hitting its limit.
Im hoping I can remove the franco updater app and its user data and boot but maybe thats not possible?
Thanks for any and all help!

Do you have a custom recovery? If so, use adb while in recovery to pull your files. If not, then flash one then pull them.
Not sure why you mentioned "boot.img" then "stock 4.4.4 kernel", boot.img = the kernel lol
Don't know why your device won't boot even after flashing stock boot.img, but if you use TWRP you can use the file manager to delete the .apk/other files.

thanks, i deleted the franco files and still cant boot.
i want top pull files but it looks like I need ADB and currently i can only get into fastboot mode.
(i'm using wugfresh toolkit, i know some say manual is the way to go but right now this is what I have to go on and have had no issues thus far with it)
i was using the button pull files in the tool kit but its not detecting the device since im in fastboot mode.
i swear I did a factory reset before and my photos were still present but many articles online say in 4.4 that a factory reset will wipe your photos.

since i can not boot, i am forced to use TWRP recovery and then go ingo CMD shell and ADB there however when I do ADB Devices i get the serial number showing its connected but then it says RECOVERY at the end.. much lke when you are in fastboot it says FASTBOOT at the end of the device.
i tried doing a pull using this:
adb shell
mount data
exit
adb pull data/media/0 c:\MyBackup
but when I do ADB Shell, the command prompt says this
~ # ←[6n
if t that prompt i type mount data then I get this:

im not sure how else to get to a working ADB to perform a proper pull if i cant boot into the device fully

It could say "device busy" if data is already mounted. Does twrp have a "mounts and storage" menu like CWM? Where you can mount data? If so, check if it is mounted there (would typicall say "unmount data" if it was mounted, otherwise it would say "mount data" if it is unbmounted)

ok so i went into TWRP and UNMOUNTED DATA
and then I went back in to cmd prompt and tried mount again and it worked i guess since theres no error. I typed EXIT and was brought back to normal windows command prompt. I then typed
adb pull data/media/0 C:\Users\srobertson\Desktop\Nexus 5 7-15-2014 DCIM
and when I hit enter it just shows a list of ADB commands as if it didnt recognize anything yet when I do ADB DEVICES it shows the device and ID

If you're going to put spaces in your folder names, you'll have to enclose the entire path in "...
Example
adb pull data/media/0 "C:\Users\srobertson\Desktop\Nexus 5 7-15-2014 DCIM"
Best to avoid spaces though.
I'll put this in the guide, thanks.

adb pull data/media/0 "C:\Users\srobertson\Desktop\Nexus 5 7-15-2014 DCIM"
Best to avoid spaces though.
I'll put this in the guide, thanks.

Thanks so much for your help
I ended up taking the leap and performing a Factory reset from TWRP and when I logged back into the phone I saw all my media was still present Whew.
just for posterity I went ahead and tried your code in ADB to make sure the quotes worked and it did so thank you very much and i will keep those notes handy for next time.

[Completed] Softbrick Recovery with backups available (not img or zip files though)

Hello,
I am trying to recover from a softbrick issue. I have a BLU Studio C 5+5 LTE and therefore can't use TWRP or CWM (At least that is my assumption, maybe someone knows different). Before getting into the softbrick state I took 3 different types of backups in the hopes that one of them could be used in case it was needed. (like this)
Type 1 - I did an ADB shell backup from a completely stock device (unrooted) I used this command-
adb backup -apk -all -f fullbackup.adb
For this method I followed this guide here-
https://linuxiswonderful.wordpress.com/2015/04/04/full-backup-of-nonrooted-android/
Type 2 - I used Titanium backup and performed a complete system and application backup
Type 3 - I rooted the phone and backed up all partitions using dd after reviewing the partition layout of the device. For example, to backup the system partition I did the following at an ADB shell-
dd if=/dev/block/mmcblk0p21 of=/storage/sdcard1/firmware-img/system.img
I believe the last operation I tried before softbricking was installing the Xposed framework module for my device (running Lollipop 5.1.1).
I am able to still communicate to my device using ADB and I can get an ADB shell. or enter fastboot mode My device presently shows the manufacturer's logo when booting and gets no further.
To recover from this issue I think I have two basic options
#1 restore from backup
#2 locate the problem that is causing the system to hang at startup in the first place
At the end of the day I am trying to find the simplest, quickest method to get back up and running. Both methods are acceptable to me. I am not worried about losing any data.
My challenge/sticking point is how to turn my backups into a usable format to get me back on track or understand the boot process enough to get out of the boot loop.
The first thing I tried was mounting my raw image files created from the dd process. I followed this guide-
https://samindaw.wordpress.com/2012/03/21/mounting-a-file-as-a-file-system-in-linux/
I ran these commands-
#losetup /dev/loop0 /path/to/my/system.img
# mkfs -t ext3 -m 1 -v /dev/loop0
# mount -t ext3 /dev/loop0 /mnt
# cd /mnt
# ls
The various image files I created all seemed to mount "ok" OK meaning that the loopback mount process worked but it appears there is nothing but a lost+found folder in the mounted image. (I'm not sure why that is.)
I am still researching methods to turn my other backups into something usable for recovery purposes.
For using the adb backup file I created, this is what my understanding is-
Adb backup uses a type of compression (don’t remember what kind). I would need to uncompress the file first. After uncompressing and being able to view the file contents I would think I should be able to put together a flashable zip file of some sort.
I think the process for Titanium backup would generally be the same- uncompress/convert file format, create/assemble a flashable zip file
The last thought I had was trying to get the system to boot. To do so, I need to better understand the boot process. I am familiar with how Linux boots as I am a Sys Admin. I know Android is similar but just different enough to make me research this further. I can pull dmesg log for anyone if that will help. I was also seeing where you could use the logcat command. (That is new to me as it seems more Android specific and not used in Linux that I know of)
If there is any other info you need to see, please let me know. I made a lot of notes about the system architecture, partition layout, etc.
Many thanks in advance for your help!

Android SDK to Backup my G6-L11

Hello everybody,
I'm new user on this forum please forgive me for my english as I am Belgian.
I try to make a backup of my Huawei G6-L11 with Android SDK.
I am on Xbuntu 14.04 (I am not a specialist but I use it for some months). I have installed the packages android-tools-adb and android-tools-fastboot and also android sdk.
My phone is connected to the PC via usb and the debug mode is active.
I followed the next steps in a terminal
[email protected]:~$ adb devices
List of devices attached
68a0f6753968 device
[email protected]:~$ adb backup -apk -shared -all -f backup.ab
Now unlock your device and confirm the backup operation.

The problem is that I unlock the phone but the backup does not begin. Why? What can I do to begin it?
I really need to do this operation as I can not make any upgrade, any changes on my phone as the memory is full
Thanks a lot for your help

Hello,
Thanks for your reply
I have tried with root and it does not function
I followed the steps I saw here https://memo-linux.com/android-utiliser-adb-pour-faire-une-sauvegarde-complete-de-son-smartphone-ou-tablette-sur-pc-sous-gnulinux/
And I can do the first steps, the problem is that the phone is not locked as it should be and the backup does not begin
Other solution?
Thanks a lot
Hello,
I become completely crazy with my problem :silly: I can't do it
I tried a lot of manipulations in order to do the backup and I found something interesting. In a file I had to create in /etc/udev.rules.d/ with the name 51-android.rules, I saw that the product ID seems change every time it is connected/disconnected of the PC. It was 1054, 1037 and also 1051. I suppose it make some trouble... Is it possible to blok it, ?
HTML:
ATTR{idVendor}=="12d1", ATTR{idProduct}=="1051", MODE=”0666"
Thanks a lot.
Hi!
With the phone ON, with root, plug USB, choose MTP, tuurn ON debug mode, it will pop up a window in phone requesting permissions to connect YOU MUST GIVE IT, need 2GB free in your sd card, use ADB and type this:
adb shell "su -c 'dd if=/dev/block/mmcblk0p4 of=/storage/sdcard1/rpm.img bs=4096; dd if=/dev/block/mmcblk0p5 of=/storage/sdcard1/tz.img bs=4096; dd if=/dev/block/mmcblk0p1 of=/storage/sdcard1/sbl1.img bs=4096; dd if=/dev/block/mmcblk0p11 of=/storage/sdcard1/modem.img bs=4096; dd if=/dev/block/mmcblk0p9 of=/storage/sdcard1/modemst1.img bs=4096; dd if=/dev/block/mmcblk0p10 of=/storage/sdcard1/modemst2.img bs=4096; dd if=/dev/block/mmcblk0p2 of=/storage/sdcard1/sdi.img bs=4096; dd if=/dev/block/mmcblk0p6 of=/storage/sdcard1/aboot.img bs=4096; dd if=/dev/block/mmcblk0p19 of=/storage/sdcard1/recovery.img bs=4096; dd if=/dev/block/mmcblk0p23 of=/storage/sdcard1/system.img bs=4096; dd if=/dev/block/mmcblk0p18 of=/storage/sdcard1/boot.img bs=4096; dd if=/dev/block/mmcblk0p24 of=/storage/sdcard1/userdata.img bs=4096; dd if=/dev/block/mmcblk0p21 of=/storage/sdcard1/cache.img bs=4096; dd if=/dev/block/mmcblk0p20 of=/storage/sdcard1/cust.img bs=4096; dd if=/dev/block/mmcblk0p12 of=/storage/sdcard1/fsg.img bs=4096'"
Now you have your ROM images in sd card. You will need a flash zip to flash it if you need it.
You can use this one, only need to paste the images inside.

Hi Persona78,
Thanks a lot for your quick answer
As I understand what you explain in your answer, you proposed me to flash the ROM of the phone but that is not my aim. I only want to make a backup for after try to increase the internal memory. I do not want to root the phone so I found on Internet the ADB program.
I plug the phone which is ON, I plug it with the USB cable, choose MTP transfer protocol, turn it on debug mode and agree with the pop up on the phone. Everything is good until the time when a message should appear to UNLOCK the phone in order to backup. This message does not appear as the phone is already unlocked and as it get blocked, no message appears. Whatever, the backup does not begin!
Thanks a lot.

Hmmm, all apps I know to do backup use root.
You can use CWM or TWRP to backup, but they don't backup cust, and I don't know if recover to images default size.
The only way I know is fashing default ROM.

I have a L11 rom, modify by me, resided and if you create in sd card a primary ext4 partition it wil send the apps to sd card automatically.

Finally, I made a manual backup by drag and drop and also with Mybackup which do not use root.

I made a reset of the phone with the manufacturer's parameters but I would like to use one other rom as they do not have any update for this model but it seems to be complicated to do it. I do not know how to backup the manufacturer's rom as I met a problem after. I think I would not be possible for me to root, unlock, extend the sd card with Gparted (as I work under UBUNTU 14.04 LTS), and make the update with the new rom, as I am not so talented with computer science.
Thanks a lot.
I tried and finally I have used Gparted in order to split the sd card. I have now 4 partitions
- swap partition (29 mb),
- fat32 partition (6.35 Gb)
- ext4 partition (23.34Gb)
try one of my versions
You can try one of my versions.

Backup Unmountable Data Partition from TWRP Stock 8.1

This works fine on my phone. If it doesn't work on yours, standard disclaimer applies about bricking, phone exploding, etc... that's all on you.
The problem has been that regardless of patches and regardless of methods to make the stock 8.1 data partition readable from TWRP, my phone won't do it. So as follows is how I've backup up and restored as an alternative. I don't know if this works well on Windows (Probably not) or MacOS (More likely it will), so its only tested on Linux.
Install adb on the computer
On the running phone, enable usb debugging.
Connect to the phone, allow the computer to access it.
Get a shell
Code:
adb shell
Enter as follows to find the block device where data is mounted
Code:
mount | grep /data | grep block
My output was this
Code:
/dev/block/mmcblk0p24 on /data type ext4 (rw,seclabel,nosuid,nodev,noatime,discard,journal_checksum,journal_async_commit,noauto_da_alloc,errors=panic,data=ordered
The first part, "/dev/block/mmcblk0p24" is what I was interested in. You can see it's mounted at /data
You're in fact looking for this specifically at the beginning "/dev/block/mmcblk0p24 on /data"
If you're confused or you have multiple mount-points or what not, or you don't understand, Stop Now, you're about to screw things up.
Copy the first part of what you have here, in my case "/dev/block/mmcblk0p24" (don't use quotes though)
Reboot into TWRP.
Make sure /data is not mounted in the TWRP menu. If it is, then no need to do this as you can back it up directly from TWRP anyway, and you don't nee this.
Backup will make an image of the entire partition, so it will be big. As follows to backup, change the /dev/block/xxxxxxx to what yours is, if it is differant. Replace xxxxxxx with what your output was, mine was mmcblk0p24 (this needs to be input correctly for backup and restore, this here is where you can screw your phone up)
Code:
adb shell 'dd if=/dev/block/xxxxxxx' > DataBackupName.img
(Above, you DO use the single quotes)
DataBackupName.img can be named whatever you want to call it.
This takes a long time, my phone writes 12 gigs or so.
The above command should exit telling you how much data was written. You don't want to have an incomplete backup because the usb cable wasn't great or the process spit the dummy for some reason.
To restore, cross your fingers (works fine on my PC)
Also from TWRP and also making sure data is not mounted:
Code:
adb push DataBackupName.img /dev/block/xxxxxxx
You need to have the correct text to replace the xxxxxx. Screwing this up is very high risk of bricking your phone.
Okay all that said, my assumption is that the initial dump won't work on Windows as it needs to direct the output to a file and I have a hunch that the syntax above for directing the output might be done differently. If someone knows how to do the backup on Windows, or can clarify if it works or not as is (after testing) I imagine that would be helpful for Windows users. Feedback in general is good for others, solutions to problems are great.
Additionally, when I was looking for this solution, the answers were a bit old and had to be mildly adapted, but there was a complaint back then that adb couldn't handle the restore. That hasn't been the case for me. A more recent adb binary might fix this if you happen to have this sort of problem.
A benefit of this method, is that if your system can mount an ext4 volume, you can also mount the image, so if you only want one file from a previous backup, or you want to remove a file from the image, or add one, that's all possible... with Linux (Linux geeks know who they are). Note that the image also contains the contents of what gets mounted at /storage/emulated/0
You can compress the image file when its done to reduce the size.
