How to back-up data from Android system recovery mode - Android Q&A, Help & Troubleshooting

Hello,
My Samsung Galaxy S4 which fell this morning and now is stuck in Android system recovery mode. Each "reboot system now" ends with the same home recovery screen. I still haven`t tried "wipe data/factory reset" since I would like to back-up my data, if possible. Is it possible to back-up data if my phone is in this state? I don`t think that USB debugging is turned on.
Can you please advise what are my options?
Thanks a lot!

Samsung Galaxy 10.1 Stuck on Logo Screen

Hi, I recently rooted my Samsung Galaxy Tab 10.1 and everything was working fine. A couple of months later, I put the tablet in airplane mode because I didn't want to drain the battery when I wasn't at home. When I got home and removed it off airplane mode, the device appeared to be frozen so I held the power down to restart it; this normally fixed most issues I've had with it.
Only this time, it boots to the screen with the Samsung logo and is just stuck there. I was wondering since I did root my tablet, is there any way to restart it properly without doing a factory reset which will cause me to lose all my data/apps, etc...
Did you try to restart device from recovery?
Could you please describe what you mean by boot to recovery?
Hold power+volume down, you will be directed to recovery, there choose reboot device, if that wont help try factory reset, or flash stock rom through Odin
Any solutions that would not wipe the data?
If not is there a way for me to access the data and save it prior to me doing the factory wipe like hooking it up to my pc and transferring the data?
I have recovery but noticed I never took a backup. I am wondering if I did a backup now and did a factory wipe; would it wipe out the recovery/root? If not; would I be able to restore the backup and get my data back?
I tried the wiping cache but no luck; still just goes to the logo screen and no further.

I had this same problem on my tab. However, I just got out of it using the RECOVERY mode as was explained above.
It will not wipe your data. Just choose the option to reboot the system and that will fix it for you. I had same concern about wiping my data so when I saw that reboot option, I selected it and it has helped to rectify my issues. My tab has finally boot completely and I'm once again able to use my tab.

[Q] Android encryption failed, factory reset doesn't help

My encryption failed, forcing me to factory reset my S4 mini :crying: But when I hitteed the factory reset button, it wiped my data (took a minute or so), reeboted, and I landed at the same screen as before. Also wiping cache, dalvic cache, and formatting /data didn't help
I've read severeal very old threads here, saying that you got to reinstall the stock firmware. Is this still possible??? Can somebody tell me where to get the right 3 part firmware for my S4 mini (DTM)???
How the encryption problem occured
HELP!!! My phone forces me to factory reset, but the SD-Card encryption key will be lost then!
I can still reach the recovery and got a backup from Titanium of all apps on my SD-Card (thank god I did it yesterday). But the SD-Card is encrypted, and the key will be lost in case I do the factory reset. I can still access the CMW recovery and even can backup the system (just /data is still not working), ADB is enabled. Does anybody know how to safe the SD-Card key/unencrypt the SD-Card?
PS. I still know date and time when I did the encryption of both storages
How the failture happened:
I started the unencryption progress, and went out of my room, the phone still plugged in.
A few minutes I came back, the screen was still black. It also didn't reacted when you pressed a key. I thought something went wrong and the phone shut down complety, so I pressed the power button for a few secs. Then it booted, but then I got the message that I got to factory reset my device.
It seems like the unencrypting has never started, but the device thinks it has started, and therefore fails to boot.
Bump
Please help me, all my game stats are stored on the SD Card and it would be horrible if I would loose them:crying:
Another bump
Other problem now, so I brought the thread back to the top

[Request] Tips to save a phone that restarts itself

Hi all, my question prescinds from a phone particular model. The problem is that for some sort of software issue, the phone restarts itself after few seconds that rom unlock appear. I'm sure that is a sw issue because in recovery mode it stays alive and when he does the application update after a dalvik cache wipe, all goes well too!
It's not possible to enable usb debug because it restarts too soon and in recovery (cwm) it's not possible to connect via adb. It's not a rooted phone. Also in safe mode it stucks in bootloop
What i can do before a factory reset?

Looks like its bootlooping ... Yes its a software issue ... I don't think u have any option other than factory reset ... Take a backup first before u do that...or perhaps u can use a logcat if u know what it is
i will try to take backup in sd card and retrieve some useful data from this.
how can i use logcat if can't connect through adb?

Storage full, now phone won't boot

Hi,
I got the message today on the phone that it could not install updates because the storage is full. Then the battery died and now it won't boot up anymore even though it is fully charged.
It is stuck at the boot screen. I can only get into recovery mode that gives me a limited number of options (like 'appy update from adb' or 'wipe data' factory reset')
It is a Wiko model Ridge 4G with Android 5
How can I make it work again without deleting all my data ie a factory reset?

I'm afraid you can't get out of bootloop without factory reset.
If your device has a TWRP, you can install that and boot from it. From there, you can copy your important data to your computer and then perform a factory reset.

Samsung galaxy A51 (a515f) stops on Android logo

Days ago My phone restarded and stoped on the Samsung logo.
I tried to do a hard reset with the recovery mode. After wipe al data and restart the phone it stop on the logo again.
Also, after the recovery menú launch it appears two images. Sems like the phone it's going to update and then appears an Android logo with the "no comand" words. Before this the recovery menú appears.
What should I do to get my phone back? since performing a hard reset from the cell phone does not work thanks
@RicardoPeyro
In order to bypass the NO command screen you can try the following
Boot phone into Recovery mode
When Recovery Menu comes up select "Wipe Data / Factory Reset" or "Wipe Cache Partition"
Once the process completes, you can reboot your phone by selecting in Recovery menu “Reboot System Now”
