[solved] adb not recognising phone in fastboot(download) mode - Samsung Galaxy S7 Questions and Answers

Hello All
I have had to reinstall stock(sm-g930f) due to an own stupid(again) mistake.
The OS is reinstalled and working and now I would like to flash Magisk through ADB. ADB recognises the phone by "adb devices" when in normal mode. When in fastboot (download mode) it does not recognise the phone. All it states is: List of devices attached
Can someone help me to overcome this, or if you have another suggestion to flash Magisk?
Edit:
after searching for a long time I read somewhere:
Do not put phone in download(fastboot) mode, only in charging mode when connected to the PC's motherboard USB port. Works flawless since, with having the relevant ADB drivers installed.

Adb is adb.
Fastboot is fastboot.
For adb, you need adb binaries.
For fastboot, you need fastboot binaries.

I have downloaded these and and haven't had any luck. Is there a detail how-to somewhere?

Probably because you didn't have drivers installed.
You need to find the specific drivers for your device model and install it.
Good luck.

I have searched for hours and all I have found seems not to be compatible with S7 sm-g930f. I have also followed this https://androidadbdriver.com/ specific to my mobile.

Did you really try to find ?
Here is the download for samsung usb drivers: https://developer.samsung.com/mobile/android-usb-driver.html
Install it and reboot.
If it doesn't work, probably you have any problem in your device manager.
I'm an user linux and I hate windows.
Good luck google'ing it.

Im having the same problem. i don't want to use the adb setup thing becuase its a virus so yeah.

have you tried Ubuntu??
windows sometimes has a lot of problem.
If you've got a driver installed that works fine you can use Device Manager in Windows. Connect your phone, find it in the list, choose update driver, and the option that lets you choose a driver from the list. Select the driver that works (mine is called MyHTC) and it should install. You need to repeat this for eachc of the three states (adb in Android, fastboot, and adb in Recovery)

Best way to install adb and fastboot after toolkit?

I was using wugs toolkit and this brought adb, fastboot and drivers. Now I would like to use adb and fastboot independent from the toolkit. I guess drivers stay the same, but what is the best way to install fastboot and adb systemwide, without having to install the full sdk?

I, personally, would use the SDK to get everything on your PC. At least then you've got all the files
After that, follow this guide:
http://forum.xda-developers.com/showthread.php?t=1161776
After that, you can use adb/fastboot from any location
Please go to my "adb and fastboot" thread which you can get to via "guides and info threads" link in my signature. This will give you naked drivers and 15 second adb and fastboot installer. Quickest and easiest method IMHO

Hey mate, I tried the tool, but it doesn't work:

@Lownita just use it for adb and fastboot. In my thread there is a separate link for drivera
@rootSU I'll try! Well, does the device have to be connected to the PC while installing any of those? I guess not? (Ofc drivers install themselves when phones gets connected afterwards).

Yeah needs to be connected because you need to right click the device in device manager. Just connect it in recovery or bootloader depending which one you're most likely to use most.

Trying to root my OPO, but ADB doesn't recognize my device.

I've been trying to root for ages, but no matter what I do I can't get ADB to recognize my device. I've tried reinstalling the drivers from I don't know how many sources as well as adb/fastboot several times, but I always get the same result:
{

In the device manager I get a yellow flag on the ADB interface:
I honestly don't think there's any way I can do it unless I get some help from you guys. So please? How do I get my computer to recognize my OPO once and for all?
I'm following this guide FYI (must be the fifth I try): http://android.stackexchange.com/questions/106856/how-to-root-oneplus-one
Thanks to the kind souls willing to give a hand.

Honestly you don't need adb portion working to do this. Have you tried seeing if your computer recognizes your opo in fastboot mode?
Turn your phone off hold volume up and power button it will boot into fastboot. Then plug your phone into your computer let it install drivers then open command prompt where your fastboot file is and type fastboot devices if it shows something your good to go follow the rest of the guide unlock bootloader and install a custom recovery and SuperSU to root.
Also if its me I would install twrp recovery.
you sure you got the right drivers?
@Seleuco try this tutorial and also check Y for install adb drivers

You need to install divers first, look at your screenshot, you have no driver installed for adb device.

Honestly I don't even know at this point, I tried deleting and installing them a dozen times from different sources, but it doesn't recognize them. Do you know any idiot-proow way of installing the drivers?

Did you also tried to install the driver manually in device manager?
See this link how you can do that:
http://www.technobuzz.net/install-nexus-5-driver-adb-fastboot-unlock-bootloader/
If these drivers don't work and or can't install then just extract Snoop05's adb installer and use those drivers :good: hope this would work now,
the issue is probably that there are so many drivers installed that they are conflicting with each other and windows is just deciding which one is better, so manually overriding it should fix it and else I guess you have to remove the old adb drivers with an program but first try these easy methods

somethings wrong with bootloader mode

hi guys, i unlocked my oneplus6 phone after that i used autoroot in toolAllinOne..all good, i instaled magisk apk and tryed to install but it says always failled. But that is not the problem, the problem is now when the phone is opened the program recognize abd device and model but when i go in bootloader it recognize abd device but model not anymore. the drivers i thing are installed well because abd is detected. Anyone know why model is not detected? I cannot install .img file for twrp.

How?
I could not even find my device when i use fastboot devices command in fast boot mode. Because of this i could not flash twrp also.
I installed drivers and connected the phone in all sorts of modes (usb debugged, usb undebugged, fastboot, system on, switch off mode).
When the phone is connected in switch off mode, i could see something like "usb device not found" message in pc. Tried changing desktop. But it's the same result.
I'm unlocked and on stock open beta 4 pie.

How to fix "Handshaking... [ERROR] UNEXPECTED RESPONSE: 0x78" or "Handshaking... [ERROR] UNEXPECTED RESPONSE: 0x58"

Hello, I installed Pixel Experience Android 13 Custom ROM. But it had IMEI issues, So I decided to roll back. When I opened SP Flash Tool, It said Select the Format All + Dowload Tool. I did the exact, But then it said, Disable verified boot or unselect the "Preloeader, Tkv, Dtbo, Trnsfs" I did what they said, Then, I flashed it completely, It said OK, I tried to boot in my device, But it wont budge. I guess it's bricked? I tried downloading an older firmware like previous version of the firmware for the same model, Then I opened the MTK Auth Bypass tool, I opened it, It used to work, But now, It gives an error:
► Installing driver... [OKAY]
► Waiting for brom... [FOUND]
● DETECT AS MTK USB Port (COM5)
► Configuration port... [OKAY]
► Handshaking... [ERROR] UNEXPECTED RESPONSE: 0x78
How to fix this error, and what could the reason be behind the bricking of the phone over no REASON?
Please guide, as I dont want to spend more on this phone as I alr went to Tech Support and spent my money there.
Thanks
[Update]: Found the Solution after 6 months, All I needed to do is to disconnect the Battery and reconnect it. Full detail on the last point in this thread I created: Infinix Fix

Dear Brother, I cant flash stock rom, unless I get the DA File, and I bypass the DA file, And the Bypass tool gives an error:

Is there anyway you could help me?
If phone can get connected by ADB then you connect computer and phone via USB-cable and run
Code:
adb devices
adb reboot sideload
adb sideload <STOCK-ROM-ZIP-FILE>
adb reboot

I went to the tech support, I just saw him opening my mobile, maybe he disconnected the battery and reattached it, as disconnecting and reattaching battery resets usb connections.
