Short version - is it possible to copy files from my phone to my PC using fastboot (or perhaps adb)? The cyanogenmod WIKI for fastboot, among others, imply that you can (under the section Examples -> Manual Nandroid Restore it says "Make a Nandroid backup, and copy the folder off your SD card to your desktop."). Sorry I'm not allowed to post the link due to being a new user, but this is what it says:
"Make a Nandroid backup, and copy the folder off your SD card to your desktop.
cd ~/Desktop/path/to/backup/
fastboot flash userdata data.img
fastboot flash system system.img
fastboot flash boot boot.img
fastboot reboot"
If it is possible, is "flash" the correct command to be using? The description of the flash command when you run "fastroot help" implies it writes data to the phone, not from the phone to the PC... Unfortunately almost everything I search for around the flash command is examples showing how to load ROMs etc, I can't seem to find anything else that points to it being used to backup data...
[UPDATE] - From what I understand you can't copy files off the phone using fastboot commands, but can using adb - so a few questions:
- Does anyone know why adb wouldn't see my device (when I run "adb devices") but fastboot does (note that I'm on the fastboot screen)?
- Does adb require debugging mode to be on?
[UPDATE-2] - Still can't get adb working, suspect it's because USB debugging isn't enabled (though not sure how I can check?). I did try using fastboot to erase the /cache partition in case the lockout data was stored in there - but this didn't work unfortunately. Looking likely I'll just have to wipe it with fastboot oem unlock
Long version / background info:
Using a Samsung Nexus S with Android 4.1
The other night someone down the pub decided to try to unlock my phone, and apparently got the pattern wrong so many times it's now requiring me to enter my Google account details.
Fine, I enter the username / pass, only it says they're wrong - I know they're correct because I've just confirmed they are by logging into Gmail. It says they're incorrect so quickly that I suspect it's not even connecting to the web to check. The icons at the top imply there is signal, but it looks as though 3G / data is off, and there's no WiFi icon even though I'm sat next to my wireless router. I can't find any way to re-enable WiFi / 3G without first unlocking the phone - which requires a net connection. So I got into Fastboot Mode and selected Recovery and the device looks as though it's doing something (deleting all user data I assumed), but when it starts up it's exactly the same - which implies the user data hasn't been erased.
Then I installed fastboot, and the drivers for the Nexus S.
When I run "fastboot devices" I can see the phone listed, however bizarrely "adb devices" lists nothing.
"fastboot oem unlock" seems to work (the phone prompts me to confirm I want to give root access & delete all user data). I haven't done this yet as I want to see if I can save my data somehow using adb or fastboot commands.
For adb to work, your phone must be booted and USB debugging enabled. In your current situation, as far as I know, a factory reset is the only option.
The phone is either in ADB mode or in Fastboot mode. It can never be in both ADB and Fastboot at the same time. ADB requires the phone is up and running, Fastboot requires the phone is in bootloader mode. ADB requires debugging turned on.
If you unlock your bootloader, you can boot the phone using fastboot and your own recovery image using "fastboot boot myrecovery.img" (notice, no flash keyword here). Booting your device with this recovery image, you can do whatever you like and the image permits, e.g. running ADB and copying files. You'll need this recovery image, though.
Thanks, I did try fastboot with a recovery image, but it currently doesn't work because I need to unlock the bootloader (which will wipe all data anyway). Sounds like I will need to just wipe it

Facing same issue.
Is there anyway so I could copy userdata.img to my pc and then delete gesture.key file (I am running Lollipop) with NO USB DEBUGGING ON in Fastboot mode.
I have gone through "unpacking and packing .img files"http://forum.xda-developers.com/galaxy-s2/general/ref-unpacking-repacking-stock-rom-img-t1081239
But it is out of my knowledge range can anyone get through it and explain me the same.
Hi! I am in the same situation... ADB not working, only fastboot... Any way to save my data? Do I need to unlock bootloader to install a stock recovery? Thank you!
Hi - I am in exactly same situation as well. I am using Oneplus 8t. Any help is greatly appreciated. thanks
I'm trying to flash TWRP, i've got ADB and i've got the Universal ADB Drivers. The device is properly detected when in EUI and my Device ID is displayed correctly when I type 'adb devices', however when I reboot into fastboot and type 'fastboot devices', nothing is listed and cannot continue.
Which drivers do I use? What is it that I need to continue?
Thanks!
Edit: Nevermind, connected it into my linux machine and got it to work easier (lol winBLOWS amirite) and finally got it to recognize the device in fastboot mode. I kept rebooting and failing to get into TWRP. I found somewhere else that before doing 'fastboot reboot' that you should hold VOL UP so you can immediately boot into twrp and make it permanent, which ended up working for me. Freedom!

I believe you need to configure in the developers options that you don't want to have the recovery overwritten on reboot. What also seems to work is to boot into the TWRP from the command line via 'fastboot boot <recovery-file-name>'
I have the exact same problem. I have installed all drivers and adb, but as soon as i am into fastboot and my device doesnt show up in the command line. If i want to install the recovery the command line just says <waiting for device> and nothing happend.
I already enabled the "Enable AT Port" Settings (http://forum.le.com/in/index.php?threads/le-max-2-x820-qpst-not-working.14820/) but i think this is not permanent turned on on my phone, because i have to repeat this step after every reboot.
Anybody got some tips?
Edit: Also booting directly into TWRP doesnt work, 'fastboot boot <recovery-file-name>' just ends up in <waiting for device>..
If you're using Win 8 or Win 10 you should turn off the driver singing verification before installing usb drivers for device.
In your case one of the drivers was blocked from installing and the systom does not see the device after it switches in fastboot/recovery mode.
I am not allowed to post urls, so google this: How to Disable Driver Signature Verification on 64-Bit Windows 8.1 or 10 (So That You Can Install Unsigned Drivers)

Thanks for this Hint! Didnt know this
Nevertheless, no improvement so far. I Unistalled every driver and installed them again, but the PC doesnt recognize the phone when its in fastboot mode

There is a chance, that your computer has installed the WRONG driver for the fastboot mode, so find any related to the phone entries in Device Manager when the phone is connected in fastboot mode, and if it is not "Android Phone/Android ADB Interface" -> remove them with remove driver checkbox checked. Optionally, if nothing changes -> try to manually pick the device driver to Android ADB Interface

I tried it now with the fifth computer and after a few strange error messages, it "succesfully" installed TWRP.
BUT: There is no TWRP installed on my phone. I followed every tip which i found how to exit the fastboot mode (pressing Vol+ & Power / Removing USB Cable / Tried TeamSpains Automatic Installer).
What is wrong with this phone ? - I think i will oben a new thread, thanks for your help!

Kampfgans: Klingt irgendwo zwischen lustig und richtig bedrohlich...
Lots of ROMs (including most CM variants) like to "automatically 'recover'" recoveries, that is they overwrite the recovery partition with a copy of the "original" every time you reboot.
I seem to remember that my first attempt to overwrite the stock recovery using "fastboot flash recovery <twrp-image-name>" also didn't succeed in making TWRP "stick".
Within the CM13 which I installed next (over the stock v15) there is a developer option to control that, but in this case I simply used a trick, which seems to bypass the recovery overwrite: I told the phone to boot the TWRP recovery over USB after flashing.
It went like this:
fastboot flash recovery <name-and-path-of-TWRP-recovery> //puts the TWRP image on the recovery partition
fastboot boot <name-and-path-of-TWRP-recovery> //bypasses the recovery overwrite logic of either the bootloader or whereever it hides
That booted TWRP over USB and allowed me to install CM13.
There I disabled recovery overwrite in the deveoper's options and I've never had issues with TWRP disappearing since.
Actually you should in theory be able to leave the stock recovery in place and still use TWRP by booting it over USB on the fastboot command line.
I install drivers and USB but when trying to go to fast boot I receive "waiting for device"
So I'm trying to install this app that needs to run an adb command in order to work. I followed all the instructions (Turn on developer options > turn on USB debugging) but the problem is that my computer doesn't recognize my phone in recovery mode, the weird thing is that it recognizes it while it's turned on. I've tried to look for answers in other threads to no avail so I was hopping that you guys could help me?
@-fg
Wondering why you are booting into Recovery Mode when it comes to execute an ADB command?
Android devices have a feature called Recovery Mode, which allows users to fix some problems in their phones or tablets. It may be useful if you notice that your device is not acting right. Technically, Recovery Mode refers to a special bootable partition, which contains a recovery application installed in it.
REMEMBER: When your device is in Recovery Mode, only physical keys will be accessed, means you have to use Volume Up and Down keys to move up and down and the Power button to confirm an option / command.
Well, the command doesn't work when I execute it with my phone booted up normally, I assumed that I had to go into recovery mode because it's the only way for it to work. Maybe there's another way to execute that command but I don't really know how
So, I recently tried to root my Redmi 5 phone and install Lineage OS into it. This is my first time doing it, so I believe I may not have understood the words I had been reading well. Due to this, I'll try to be as descriptive as possible with the actions I had taken that led to my device being stuck.
I had followed this guide, for the most part: https://www.getdroidtips.com/lineage-os-17-xiaomi-redmi-5/
As per the guide, I performed the following actions:
Enabled the developer options
Registered my device to my Mi account
Enabled USB debugging, OEM unlocking
Rebooted in fastboot mode using the ADB tools through CMD (adb reboot bootloader)
While in fastboot mode, I used the Mi Unlock tool to unlock my device.
As per my understanding, these steps would unlock the bootloader. I rebooted my device, set it up (the phone behaves as if freshly booted) and checked the settings menu after enabling developer options again. It shows the bootloader is already unlocked and that Mi Account status is also unlocked. I enabled the USB debugging options again and carried on with the guide.
I then downloaded the rosy TWRP file (version 3.5, I think).
I even downloaded GApps and Lineage 18.1 OS
I tried to copy the above files into my Redmi 5 internal storage
The Lineage and GApps file failed to copy, but I was able to copy the TWRP file
One thing to note here, I am not sure if my USB cable is faulty or if my phone's micro USB port is faulty or if my laptop's USB ports are faulty. When the phone is connected to my PC, it is extremely lousy. If I shake the cable even a bit, it disconnects and reconnects. When I try to use the file explorer to copy the files from my laptop to the android phone, it usually fails for large files or large quantities of small files. I believe this was the reason behind the failure. Nonetheless, I decided to do the TWRP part first.
The guide said to reboot in recovery mode and that would take me to TWRP recovery mode. Well, it did not! It took me to a menu that had the following options:
Reboot
Reboot to System
Back to Main Menu
Wipe Data
Wipe All Data
Back to Main Menu
Connect to MIAssistant
I assumed I had entered recovery mode incorrectly, so I followed the link in the guide on how to enter recovery mode. It suggested using the ADB tools.
I used the command: adb reboot recovery
It did the same thing that I had done. So, I assumed that that is the recovery mode, but I am unable to enter TWRP recovery mode. There was another link that would show me how to do this.
I followed that link and downloaded the files that was mentioned. However, the guide tells little to nothing on what to do with these files. The only file that was used was the rosy twrp file.
I enabled the USB debugging mode on my phone.
Opened CMD from the folder with ADB
Entered the command: adb reboot bootloader
Phone enters fastboot mode
Entered the command: fastboot devices
I can see that a device is connected
Entered the command: fastboot flash recovery rosy-3-5.img (I renamed it for convenience, I believe that was allowed because every website had different name for their file)
I then rebooted into recovery mode by first rebooting it normally: fastboot reboot
Then entering the command: adb reboot recovery
It still showed the same old recovery menu. Nothing had changed. I looked around the internet and found that I could boot with the TWRP image by entering the command: fastboot boot rosy-3-5.img
This opened the screen that I was expecting, but it did not open the chinese menu at all. It directly went to the screen that had options such as Install, Wipe, etc.,
I rebooted normally and then tried to transfer the GApps file and Lineage file into my phone. As usual, it was failing. I tried to use the adb push command and it still failed but with an error saying "permissions denied"
At this point, I looked up how to get root permissions and I learnt that I had to root my device. I looked up how to root with Magisk and SuperSU. The guides all required me to boot in TWRP recovery and then install the files from my phone. Unable to transfer the files to my phone, I uploaded the files to my google drive, and manually downloaded into my phone. I boot up rosy (TWRP recovery, or so I think) using ADB tools. Unfortunately, it does not recognize any of the files in my internal storage. Everything is empty.
Defeated by this, I decided to let it go. I had a factory reset Redmi 5 at the time. I then watched a video that showed how to root with Magisk, but wasn't specific to Redmi 5, it was a generic video for android devices.
I installed the magisk manager apk into my android phone.
Then I copied the boot.img file from the Lineage folder into my android device. Despite the OS being 600 MB large, the boot.img file was only 11 MB.
Anyway, I patched the boot.img file using magisk manager.
It created a file called magisk-patched_1pTOD.img (I'm a bit unsure of the name, but it was similar to that).
The video said that I should copy this file into my laptop and then reboot my phone into fastboot.
Once in fastboot, I had to enter the command: fastboot flash boot magisk-patched_1pTOD.img
I believed that this would root my device and grant me root access. I don't know what my actions were actually supposed to do, but my device is unusable for all intents and purposes. I rebooted the device and it shows the Mi logo for a brief moment and there's no light. An empty dark screen, it's not even a black screen. It's like the display fails to work. I can switch into recovery mode and into fastboot mode but normal reboot did the same.
Thinking that I bricked my phone, I tried to unbrick it.
I downloaded the fastboot rom for Redmi 5 rosy and then installed the Mi Flash tool along with the drivers for it.
I then selected the correct ROM folder (it kept showing up as can't find flash script until I was in the right folder for it)
Rebooted my phone into fastboot mode
Hit refresh on the Mi Flash tool
It showed my device
I chose Clean All option
I hit flash
It goes up till 97%-ish and then fails with an error saying "flash system error".
However, I noticed that now, I can see that the Mi Logo doesn't disappear now. I can still go into recovery mode and fastboot mode, but normal reboot takes me to the permanent Mi Logo Screen. I cannot even shut it down. It auto reboots to the Mi Logo Screen if I do so.
I connected my device to my laptop and then opened the ADB tools.
I entered the following command to see if it's recognized by adb:
adb devices
It did not. I then switched to fastboot mode manually by pressing the Vol Down and Power buttons.
Then entered the following to see if it is recognized in fastboot mode:
fastboot devices
It showed my device there. So I used the following command to reboot and see if it is recognized in fastboot again:
fastboot reboot
While it shows the Mi Logo screen, I typed the command:
fastboot devices
It still shows my device.
I concluded that my device is in an infinite fastboot loop. I cannot boot it up normally. I cannot flash the Redmi 5 ROM into it either. I cannot use my phone.
If anybody has actually gone through this entire mess that I made, and has figured out what went wrong or at least how to fix it, please help me.
Message me on telegram @benzoylperoxide
Hope I could help you with this situation.
If you got data, download fastboot rom based on nought and fastboot rom 9.5.30
Download latest miflash tool from miglobe website.
Install proper drivers from miunlock tool zip file.
And Hope for the best.
Ping me tommorow at anytime.
Good night Bro

Flash system error in MiFlash? Probably the stock rom you downloaded and extracted is corrupted.
Please try flashing MIUI 9 for your Redmi 5.
Yeah, users have had issues with twrp being replaced by stock rom.
For TWRP,
fastboot flash revovery (recovery name.img)
Fastboot boot (recovery name .img)
After that flash your custom rom after wiping system,boot, vendor, data and cache, Internal format might be needed if it's encrypted.
Then, after custom rom is flashed, flash gapps and then twrp zip in TWRP, yeah you saw it right, flash twrp zip in TWRP. This way, twrp won't get replaced.
You can give directly flashing TWRP and flashing custom rom the way I told, Flashing Miui isn't important if your goal is to flash custom rom.
Hi!
I'm still on my way ro root my Samsung Tab SM-T725, after upgrading to Android 11. Before Android 9 was on the device, succesfully rooted via Magisk. Updating and keeping the root status didn't work properly, the flashing process in Odin failed. Therfefore I had to flash the latest stock recovery, successfully. So now I have Android 11 on my device but no root. The bootloader is open and USB debugging enabled.
I tried the method described here. But the flashing in Odin failed again. So now I try to follow the instructions on the Magisk website. If I get everything right a processed recovery.img has to be flashed via ADB/Fastboot. That's new to me and I have questions.
- Is fastboot and download/recovery mode the same? Booting to the recovery and following "reboot to bootloader" leads to the turquois "Downloading" window. The same occurs when prompting "ADB reboot fastboot" e. g. Again the mentioned Downloading window shows up, nothing (special) with fastboot. Is that correct?
- Will therefore all fastboot commands not work? And only ADB is possible on my tablet? Is that common for Samsung devices?
- Can the flashing of the patched recovery.img (for Magisk) be done with ADB as well? Instructions always mention fastboot.
- My device doesn't show up in ADB when being in recovery mode. In normal mode it is listed when entering "ADB devices". Trying again in recovery mode the list stays empty - and all other commands have no effect. Current Samsung and Google USB drivers are installed. How could that be solved? Without ADB (perhaps fastbood) running in download mode I shouldn't be able to flash (and root the device) as planned.
I hope I described everything properly. I'm not that Android expert - but successfully managed to root a couple of devices over the years.
Samsung devices dont know of Fastboot mode. But you can run them in either Recovery or Odin / Download mode or Normal mode.
Running Samsung devices in Download mode you can flash ROM or update system in the Android device. When the Samsung device has entered Download mode, the device will boot from external sources. You can also make the stock ROM replaced in Download mode.
ADB mode is the Normal mode.
In Recovery mode ADB - with some exceptions - isn't working
Because your device is a Samsung one the Google USB drivers are senseless. Remove them to avoid conflicts.
Thanks for the quick and helpful response!
That makes clear why the tablet didn't show up in ADB. And that all rooting efforts for Samsung devices via that way should be obsolete. Strange enough that Magisk doesn't mention this on their instruction site.
So I'll have to try on with flashing a patched AP via Odin - and hope for a solution for my fail-problem.
