Pls help recover data - Android Q&A, Help & Troubleshooting

So my phone screen just went black and doesn't work anymore. I wanted to adb pull all files from my phone (everything takes up 17gb, so It wouldn't be a big deal to transfer everything and sort through it on my PC), but when I boot to TWRP via command line and try to decrypt the phone the fs is still encrypted, what am I doing wrong? Or maybe there's a better approach for this and I'm just stupid? (attached is my pattern drawn on a random png from google and the commands that I tried to use) Thanks in advance

AFAIK device's /data partition automatically is turned to an unencrypted state if you do a backup of this partition via the adb backup
Example:
Code:
adb devices
adb backup -shared -f C:\backupname.ab
You may use
android-backup-processor
Download android-backup-processor for free. Android adb backup extractor and packer. None
sourceforge.net
to convert the .TAR formatted backup into a .ZIP formatted file.

It requires me to unlock the phone to do that. I think i'll just buy a USB C to USB A and HDMI dongle to view my phone screen on a monitor and operate it via a mouse. That seems like the easiest way out.
Thanks for the help, though!

Bootloot... please help

So it seems that my HTC ONE has no OS installed, I am able to get to the HTC logo and thats it. I reboot into bootloader and are able to install CWM and TWRP but no luck installing ARHD rom via adb sideload method, it just fails. Any hints on how to install a rom either stock or otherwise? i have a cwm backup of my stock rom rooted odex on my computer but it is not a flashable zip. Any help will be greatly appreciated. Thanks in advance.
(i have a mac if that matters)
if you aren't back on cwm flash that recovery.
boot to it
push your backup to the phone with ./adb push /foldername/* /sdcard/clockworkmod/backup might be backups, I can't remember, but you can check with adb shell
./adb shell
cd /sdcard/clockworkmod
ls (that is a lowercase L)
that should give you a directory listing.
after you've successfully pushed the backup reboot to recovery again and restore it.
This should do the trick

Hy gunnyman, when I push the folder to the sd card it always decompresses and send the individual files to the system not the full backup folder so i can select it from the backups menu. this is the command I used ./adb push may6.zip /sdcard/clockworkmod/backup
I also pushed the decompressed files to the sd card since it looks like it instals all files needed for os to work with the following command ./adb push may6.zip /sdcard
I reboot system but still stuck on HTC logo.
May6 is the name of my backup and when i use the ls command it has a .zip to the end.
So can you let me know how to sent the complete folder to the phone to be placed on the backup folder and thus be able to be selected under the cwm menu? Thank you so much
Unzip it. Send entire folder uncompressed
You don't restore a backup the same way you flash a rom. It's a separate menu option in recovery

yes its unzipped. took off the .zip name and sent it to the backup folder and it still sends the uncompressed files. Once I go to restore from backup folder I get a -System/ and -Meta-INF/ files and no file with -May6/ or something like that. So i try to restore from -system/ but it says md5 sum dont match.
Any ideas?
No, I don't sorry

It is essential that you have a backup of the EFS partition and a way to place it back - the first two ways that I would think about are:
a) use a good recovery - like Philz recovery, that has commands to restore EFS
b) if the format of the backup is not exactly right you might be able to boot in recovery and use ADB commands.

I am new to adb commands. Will phylz recovery help me enter the commands? if yes then i shall be replying with the sd card efs tar file name. Will then you be able to guide me with the commands based on the tar file?
Thanks all of you in advance.

No for ADB you boot into recovery, connect your computer via USB and run the ADB commands from either Linux Terminal or Windows Command Prompt.
The tool here:
http://forum.xda-developers.com/showthread.php?t=1703488
May help if you're new to adb.
Otherwise it's a case of downloading and installing the drivers for your phone and the Android SDK http://developer.android.com/sdk/index.html
Thanks for all your replies.
Just wanted to confirm if i have the efs backup in sd card as under folder backup_efs and there are two files in tar.gz format will i be able to use the phylz recovery to use this replace my efs folder? if yes then can you guide me the steps please.

I do not remember right now what creates an backup_efs folder but it really does not matter that much - the tar.gz is a "file archive" and .img is usually a partition image. Each could have minor advantages - the .img also contains the entire filesystem of the partition (and will work easier if the filesystem is bonked) but a tar.gz backup is more versatile when you have bad sectors or a changed partition.
Under an advanced recovery like Philz you would just navigate some menus and try to restore the EFS - see the info in those specific threads.
Under ADB you need to have stuff (drivers and some programs) installed in your PC, you connect the phone on USB and you run ADB commands from the command line.

CWM nandroid copying in KitKat 4.4.4

I've been using Android and CWM for years with no problems till now that I'm using a rooted KitKat ROM (SlimKat). By default root is not enabled in SlimKat, but I did enable it along with USB debugging. I have CWM installed and it made a nandroid backup on my Moto G (1st Gen. which doesn't have an SD card). I want to make a copy of this backup and found it in /data/media/clockworkmod. However, to see this I had to use Root File Manager as a non-root user cannot see this directory.
So how do I copy this?
My thought was adb. However, even adb won't let me copy this to my Ubuntu Linux pc.
Marty
EDIT:
I thought running adb as sudo would work. It does on some directories, but not this one where the CWM backups are. Here's what I did in Ubuntu:
sudo adb devices
sudo adb pull /data/media/clockworkmod/
remote object '/data/media/clockworkmod/' does not exist
got it! I had to use another app and OTG to a USB flash drive. For some reason Root File Manager kept shutting down whenever I tried to write these backup files to my USB flash. SlimKat was installed with an app called Simple Explorer. It saw the same directory once I gave it root permission and then was able to copy my 2 nandroid backup folders to my USB flash drive.
Marty
it didn't work. Appeared to, but the file size isn't even the same Maybe if I write it to an ext4 partitioned USB flash it would get it right?
Marty
I think all that did work, but I found an official play store app for CWM called CWM Backup Manager that pulled the CWM backups to a place where they can be copied.

Can someone share their /persist contents with me?

Hi all,
Did something stupid that erased my /persist folder. The folder exists now and most of the sensors and data has been restored but for wifi. The wifi bin files are missing, so if someone is kind enough to share the contents of their /persist it will be really helpful thanks.
On a rooted device, use a root capable File manager to access the /root folder of your moto z.
in system/persist, copy the contents and share it here.?
XT 1650 3
And also their system/etc/firmware/wlan folder please?
That doesn't work. The binaries are bound to the device serial number and the whole thing is then signed by motorola.
For now, don't do anything more to your persist folder! First, you need to save what's left to save.
Try this: connect your phone with the PC, boot into TWRP recovery..
Code:
adb shell "dd if=/dev/block/sda3 of=/tmp/sda3_persist.bin"
adb pull /tmp/sda3_persist.bin
This is the current partition image. You may be able to reconstruct the missing files and filenames.
However, chance is that you removed just the mount point of the persist partition.
Reinstall system partition and see if that brings back the persist folder...

Thanks for the reply.
/persist is now mounted and phone is booting and everything else is working (bluetooth connects, sensors are working etc) only wifi is not working.
Log Cat is not too helpful, just says wifi driver cannot load. System status gives IMEI number, bluetooth MAC address are shown. But Wifi is shown as 02:00:00:00. Not sure what is wrong! Hardware gone?
Thanks
Hm, you should backup your modem partition:
Code:
adb shell "dd if=/dev/block/sda16 of=/tmp/sda16_modem.bin"
adb pull /tmp/sda16_modem.bin
Afterwards, maybe you want to try this modem backup image from another moto-z...
I have no idea wheather that's locked a serial number or if it is just genereic. Make sure you have a backup of your current modem parition!
Flashing is just the commands slightly reversed...
Code:
adb push other_modem.bin /tmp/other_modem.bin
adb shell "dd if=/tmp/other_modem.bin of=/dev/block/sda16"
No Luck
thanks, can you confirm what is the contents of the /persist/wifi and /system/etc/firmware/wifi/?
Just want to check

My booted system contains a /persist/wifi folder, but with no content
/system/etc/wifi contains 5 files: p2p_supplicant.conf, p2p_supplicant_overlay.conf, WCNSS_qcom_cfg.ini, wpa_suuplicant.conf, wpa_supplicant_overlay.conf.
Are you sure, you redtored all partitions properly? Maybe FSG as well, though I think it's just cellphone related & erased modemst1/2+cache?

The phone is booting without any errors at all, so I am not sure!
Same for me, so issue is not with persist. The etc/firmware/wifi is different for different people? I have 3 files, one .ini and 2 bin files- one for 2G and other for 5G- both are empty! Beats me!
I dont suspect wifi hardware going kaput so easily! But there are quite a few people who raised this in other device forums, but no one seem to have succeeded!
edit: I am assuming /etc/firmware are changed when we flash a new rom and the fact that I flashed the stock ROM a couple of times did not help means that the problem is not with /etc/firmware folder? Really clueless!

Extract from "adb pull" backup?

Hi.
tl;dr
How can I extract from a backup made with "adb pull" ? Thank you.
more
Any help would really be appreciated here...
I have a backup that was made by booting to Recovery, then running:
Code:
adb pull /dev/block/mmcblk0 my_phone_mmcblk0_$(date +%Y%m%d).adbimg
How can I recover the contents, please?
According to fdisk, the backup archive (i.e. the .adbimg file) contains a GPT partition table, and 12 partitions (of varying sizes) of type "Microsoft Basic Data". The largest of them is 11.5G; I'm guessing that's where the data I'm looking for are.
TIA
EDIT: If it's relevant, I use Linux and macOS, and I'm comfortable with the command line.
Look to the XDA forum for inspiration.

I read that, thank you. But it's not the same, is it(?)
adb backup != adb pull
(...Or am I wrong?)
