Ok, I can see that adb is unlikely to work, but worth a try if saving the photos was important. The “internal storage” where we expect to find the photos is mounted at
/sdcard (I know, sounds improbable; the external SD card is at
If you cannot get a positive reply from
adb devices that door is closed
I guess. PS, unless you are able to boot into Recovery mode, mentioned below.
Please be sure to keep the phone fully charged. Please confirm that when the phone is off it will charge ok and keep it well above 60% for the job of replacing TWRP, if you decide to go for it.
Replacing TWRP with no user errors, will leave all the contents of the phone untouched. Odin is a Samsung product, so might tend to draw you to return to Samsung, so just follow the tutorial with care and you will have no problems !
When I wrote
Alternatively, reflashing the recovery may be worth trying. When you mentioned Odin …
I expected all the links beyond that point to cover your situation including the TWRP link; you would use the most recent TWRP, in the format required by Odin, see tutorial.
I guess the long [HowTO] might have looked a bit daunting, but reflashing TWRP is not hard and is only a very small part of that full tutorial. Please study only Sections 4, 5 and 6. I will not rehash any of that information, it was written by an expert, there are points where you have to be very precise, but it is not hard if you stay on course.
I doubt anyone managed to flash /e/ on to a Qualcomm (hero2qltechn) – I say this as it has a locked bootloader.
You will need to be able to boot into Odin mode on the device, described here, Know your hardware - Samsung. Boot modes also given at the foot of this page Info about Samsung Galaxy S7 Edge - hero2lte.
So, first, we just need to be sure you can boot into Download mode successfully. Once you do that hero2lte should be displayed in tiny print top left. (You can do this before you do any downloads, hopefully will be nice to see the phone in a stable mode again !)
While experimenting with Boot modes, you might as well try to see if the phone might possibly boot into Recovery mode. Seems unlikely, but silly not to try, as if successful that would give us other options.
Please call back if you do not see Odin mode, or if you do see a stable Recovery.
someone suggested using the following video to flash the firmware on the device
That would not be a good way to approach this, as we cannot be sure a Samsung ROM would not overwrite the internal memory. You would recover the phone for sure, photos unlikely. If we really cannot fix /e/ I would be disappointed.
(I am not good with videos; his presentation left me more confused than I started.)
Of course you do not want to overwrite the system. Your reported error is that Recovery was not found / could not be read. So we propose just to replace the damaged Recovery, a relatively small part of the total software.)
Please tell me anything else is unclear.
