Download mode?! Flashing possible via fastboot?

Hi everyone,

Having read loads of threads it looks like the only way to root the S7 is via the Download mode.

I have tried all I could but I cannot boot into Download mode. :eek: Power + Vol Down + Home flash the screen a bit and that is it, device does not even boot. I have to let go of the buttons and then boot it with just "Power" button. Also if I try to boot into recovery I only see Droid with open torso in red. Should I try flashing stock recovery? Can someone share it or point me where to get it please?

The best custom boot I get is Fastboot (via adb) or the chinese-menu that allows to wipe the device clean or test sensors etc. When trying to flash TWRP via fastboot I get "FAILED (remote: invalid kernel & ramdisk address: images overlap)"

I have an SM-G930F Snapdragon device (confirmed by CPU Z)

Is there a way to flash TWRP or root the device via fastboot at all? :confused:

Never had a device that I couldn't boot into Download or recovery mode.....

Asus Zenfone 2 (ZE551ML) Stuck at Asus logo screen. Cannot enter fastboot menu.

As mentioned in the title of the thread, my Zenfone 2 is stuck at the Asus logo screen. I tried installing an OTA update with the phone being rooted.
To solve this initial problem, i flashed Temp CWM with the help of my computer. I successfully got to the recovery menu and attempted to wipe all of the phone's data. I don't know if it did or not, because it got stuck on this process for 10 minutes, apparently not doing anything. So I did something that may have completely f****d the phone. I restarted it during the 'wipe'.
So here came the second problem: I cannot access the Fastboot screen anymore, therefore I cannot flash anything, and it still won't open. :crying:
Desperately, I even tried using the Asus Flash Tool to flash its original firmware, while at the logo screen. It won't move.
So, in case someone actually knows how to solve this, or there's someone with the same problem of mine alongside which I can mourn my dead phone, I'll leave this thread here. I also have an additional question: is the warranty valid in this situation?
Thank you.

[Q] i cant get TWRP recovery installed via either , SP Flash tools nor Fastboot

I did everything that was stated in the how to's but to no avail. additionally i cant get TWRP installed via fatboot, i have checked and crosschecked usb debugging and unlock OEM , but i cant get it to work , with SP Flash my phone pops up and vanishes in the hardware manager withing fractions of a second so it doesnt work with the sp Flash , in fastboot it wont let me download to recovery even if i use the command line oem unlock , because the volume up button that you have to use to accept[yes] doesnt work , only the vol down[no ] button has an effect, anyone any ideas anyone?
?

Restore Download mode from Fastboot

Hi,
I have a d415 that i booted into fastboot mode with and wanted to unlock bootloader with. I then found out that it was already unlocked. Now i would like to restore download incase i screw anything up. I have the laf.img. Where do i go from there? None of the commands i type in fastboot mode work, possibly because i didn't correctly install the fastboot and adb drivers. If that is the problem, can someone give me clear instructions on how to download them, thanks. Instead, i used the basic adb and fastboot files from a different thread from android sdk. Adb doesn't even work anymore for me now. Please help
Thanks a ton in advance!

Unable to run android fastboot even after replacing the screen

Hello!
At its OPO I changed the display the frame and battery. Installation went without any problems. Unfortunately, after launching the phone started only Cyanogen Recovery. Display and touch functions entirely without any problems. So I wanted to re-install CM13, but the phone does not run fastboot. You can not run from Cyanogen Recovery or VOL + POWER-UP. The phone always starts to Cyanogen Recovery. I tried this yet through ADB, phone are detected as recovery (so drivers are probably fine), but when you try to fastboot command ends "Device waiting." Thank you in advance for your help and answers.

[UNLOCK] [H815] Fastboot won't recognize my LG G4 in fastboot mode...

First I must say, I searched all over the internet for answer to this problem. None of the topics I read had matched my problem.

I want to unlock my bootloader so I can flash custom recovery and get root access.

When I want to access the bootloader ("adb reboot bootloader"), in my phone all goes fine (I see on my phone the Fastboot instructions, etc). The problem is in my computer that fastboot won't recognise my phone anymore. When I want to get the device-id, fastboot is stuck on "waiting for all devices". When I want to see the list of devices, ("fastboot devices"), I get nothing, wether my phone is on bootloader mode or not.

I installed all the LG drivers, including the ADB one. I am in USB debugging mode, and I disabled OEM protection.

Android version is Lollipop.

I need help on this matter, thanks in advance.

Won't boot past fastboot screen - CM13

I'm currently running CM12.1 on my HTC One M8, and have been successfully doing so for the past 6 months.

I decided to try and install CM13 today after all this time, and the CM13 and Gapps install were clean (i.e. TWRP reported it as successful) Then when I clicked reboot system, it loads into fastboot for some reason, not into the normal reboot screen.

Even after rebooting 5 or 6 times, it still repeatedly goes back into fastboot. Anyone had a similar problem who could help me out ?

I backed up, therefore am back to 12.1 for now.

stuck on fastboot

Hi,

I have a problem with my phone (Mi4i, original rom). Last thing I did was unzipping a file then it rebooted and got stuck into the black screen and log of Mi4i. I tried to go into a special mode and didnt find recovery but a fastboot mode (pressing POWER + Volume-).
Q1: What happened ? is my rom dead ?
Q2: I have some important file on the phone, is there a way to download the files ?
Q3: What rom should I use to flash it again ? Im on linux.

Thanks!

Hi there

Hadn't used the phone for awhile so charged it up but whenever it starts it goes straight to Fastboot. No other screen appears.

I have gone in to HBOOT and done a factory reset and still the same.

The Fastboot page says

Software status modified
