I have a Samsung Galaxy S3 with broken screen, how can I get into recovery...
Second question, is there ADB in recovery?
yes you can enter recovery without touching the screen.
the requirements.
1. your pc must have adb installed.
2. adb drivers for your device must be installed on your pc
3. your device must be rooted.
4. developers options must be enabled on your device.
so to reboot into recovery
launch adb
type
adb devices
it will show the connected devices
it should be bunch of numbers
then
type
adb reboot recovery
thats it !!!
hit thanks if i helped you in anyway
Hello, thanks for tip, but...
I need adb shell in recovery, because my screen is black and I don't have USB debugging enabled. Is there any way?
Hello,
Recently I flashed a CWM file on my android 'Lava Iris X1 Grand'. Now my phone is stuck in a bootloop. For some reason i cant enter recovery mode even before my phone was stuck in a bootloop. I am not sure whether my phone has USB debugging enabled or not. I have even rooted my android with KingRoot. I have downloaded your Minimal Adb and Fastboot but it cant find my device.
Overall problem:
1) Phone Stuck in Bootloop
2)USB debugging enabled ? Not sure
3) Can't enter recovery mode
4) ADB wont find my device
Note : When I used Minimal Adb and Fastboot, when i type Fastboot devices some numbers appear but when I used the command 'adb devices' my device is not shown. I have a backup at my phone through the Flashify app but since recovery mode cant show I cant recover it.
Please help me out here. I don't know what else to do.
Thank You in advance
Fixed
Sorry posted in wrong section
My phone is fixed now using SP Flash Tool
OEM unlocking and USB Debugging enabled.
ADB never finds the phone in my windows 10 install no matter what drivers I force it to use. - Tried USB 2 and 3.
Fastboot does find it if I manually start it in fastboot mode, but it can't do anything to it
Fails to write when doing oem unlock
Just sits there if I tell it to write the recovery image.
Phone functions fine, I just want root and a 3rd party rom to be rid of any built in spyware.
Any ideas? any way to root it without flashing then I can just have the twrp app flash it?
Nevermind, found a way around it. This dialpad command made it work

Hope this will help someone with trouble getting ADB/Fastboot to work. I assume you have a similar environment to me: Windows 10, with working ADB drivers on another device (LG G4 in my case)
Set up LeMax2 in developer mode and enable USB debugging as usual.
Plug in usb and dial *#*#76937#*#* check the box that says "Enable AT Port"
The device should immediately give you the approval message for USB debugging.
Note: This will not stick after a reboot.
Once I had this working, I did an adb reboot recovery, but fastboot still did not work. With the device connected and at the stock recovery screen, I had to open device manager, delete the LeMax device, and allow it to detect again. Finally it appeared in fastboot devices and I was able to flash recovery.

I have Samsung Galaxy Tab S2 that I attempted to root earlier today. I used Odin and CF auto root method. Everything appeared to go fine, until it restarted itself after it was done. When it booted back up, the WiFi was not working. When I turn it on, it is simply stuck on "Turning on...." and nothing happens.
Problem 2: When I connect the tablet to a computer via USB cable, it does not recognize it. I'll hear a chime, so it detects it, but it does not show up in the file explorer. The tablet is set for a MTP USB configuration.
I tried a factory reset, but that did nothing.
I'm not sure what to do now. I do have a micro SD card, so I'm able to move it back and forth from the tablet to my PC to install APKs and other files. I'd like to try flashing a custom ROM to see if that fixes it, but now I'm not rooted. I used the SD card to install a couple of the one click root apps, but they were either unsuccessful, or require an internet connection to use.
I don't know if it's possible to actually install a custom ROM on a device that doesn't have internet access and can't use a USB cable.
If anyone has suggestions as to either of my problems, I'd love to hear it, because as of now I can't do anything with my tablet.
You can try to:
wipe data/cache from recovery and reboot it again to see if the wifi error still exists, or you can flash it again.
You can get and use adb/fastboot, if you haven't already, and check if fastboot (execute fastboot devices in cmd) recognizes your device after the chime sound. If you're lucky and your device is displayed, you can flash it again. All the best!

Thanks. Executing "fastboot devices" returns an empty list, however "ADB devices" returns some sort of serial number with "offline" next to it.
edit: I've been running adb kill-server and adb-start server commands, followed by adb devices, and that will switch the device status from "offline" to "unauthorized". I'm not sure how to fix that. I navigated to my .android folder on my PC and deleted the adbkey file but that didn't help.
In developer settings Enable USB debugging, revoke current USB debug authorizations and allow your PC's fingerprint. You can also enable OEM unlock in case you plan to play with the bootloader and custom ROMs.
Next in cmd after plugging the device in, check if it gets detected: adb devices
If you get the list you've mentioned, execute: adb reboot bootloader
This should boot your device into the fastboot mode where you have full access to your phone, so be careful what you're doing.
If you need more info on fastboot and adb, check out the forums.
Good luck!

Unfortunately it's still showing the device as "unauthorized". I've toggled developer options and USB debugging on and, and repeatedly tried "Revoke USB debugging authorizations" but it hasn't help. I can't execute the adb reboot bootloader command while it's unauthorized.

Have you been asked for a new computer ID to accept after revoking old ones and plugging the device in again?
As long as you don't add new fingerprint of your computer to the device, your device will be unauthorized.

You need to restock your tablet via odin (to put modem back aka Wifi)
After you restock Install Twrp and install magisk to root, instead of cf-root like you did (this will not breaking the safety net or knox even the modem)
(Note:before install magisk backup your "BOOT" via TWRP)
Have decided to root my phone with Adb and fastboot devices in Windows 10 and also installed drivers sucessfully and i can se my phone in cmd when i type fastboot devices.
Have unlock the bootloader in the phone and Enabled USB failure search in Advanced settings in developers mode.
When i loaded the Twrp file in cmd with adb i could copy and write the file to my fastboot device but when i reboot the phone into bootloader i se that download mode are disabled.
How can you unlock download mode ?
When i try to reboot into recovery mode i get the Android bot with a red triangle into it.
Im guessing that happens for i dont have download mode enabled and im wounder is the Twrp file on my phone or have that setting stopped this process?
