I have another smartphone that I can use. I’m just asking if I prefer to send back the new one or keep it.
But I think I shouldn’t take any risks with the smartphone. I looked again phone infor (Settings …) to see if I have the right model, which I do have.
As described in this forum post (Samsung - Galaxy S10+ - beyond2lte - Documentation Suggestions - #9 by Xenthos), this must be the SM-G975F/DS.
I would like to ask a short question at this point. Does the recovery look like in the image?
If yes, it could be that the error could be right there, because I don’t see this picture. But for me it looks much more like a line interface with several entries in blue.
If that were the reason, it would also be clear why the signature cannot be verified. I assume that the recovery tool of /e/ does exactly that, and I probably end up with the one from Samsung, which it just can’t do.
Install from ADB completed with status 2.
Installation aborted.
Is the point of failure … as if the recovery is wrong / non-functional in some way.
But now your image of e-recovery is e-recovery but why is it showing version 0.14 ?. [1]
I think I would be going back to reinstall recovery, and double checking all pre-install instructions at the same time. Ensure your battery level is at over 60%-70% at all times.
Was the phone newly delivered to you ? Had you had it online (and preferably with a SIM card) to have the phone make some connection with Samsung remote monitoring ? (I always think that instructions are written from the point of view that you have had the phone in normal use for a minimum of 7 days before attempting a Custom ROM). Hence the reason for
[1] Edit I am not a user of e-recovery, perhaps someone could chip in with current version numbering seen on their phone
Yes, /E/ Recovery is like in the picture… If you don’t see it then you don’t have /E/ Recovery installed… and I suppose you try to install the /E/ OS ROM using the original phone recovery… which of course doesn’t recognize the ROM…
And then you get to my first post:
"Most of the problems with Samsung phones come after the writing of /E/ OS recovery because the phone reboots automatically and if you don’t pres the right key combination the phones erases the /E/ OS recovery. "
On flashing my S9+ I had to repeat the flash of /E/ recovery at least 4 times (and I’m quick)…
Wonderful! Then I have exactly two good points to start from. On the one hand the cable that I will test and then of course the e-recovery, which will be the probable explanation for the problem. I’ll get back to you when I get there. Thanks!
I’m sorry that I wasted some of your time here too. I got the picture from the forum, where “my” (similar) problem was described by another user. From there I got the “version 0.14” picture.
I think @Cooler was right, and I started the Samsung stock recovery instead of the /e/ recovery.
I have to look again more closely if I really get the ROM transferred to the smartphone.
I will report.
That’s all quite complicated. If I think about it, I have installed /e/OS and other custom ROMs on Samsung S4, S6 edge, S8+ and S9+. So far, I have always managed to do it. I am confident, with all your help, I will somehow manage it again.
Is this a prerequisite to flashing? I want to flash Lineage OS on some phones and have been wondering about the necessity/importance of vbmeta.
I’ve putted Lineage OS with microg on a OP5 previously having /E/ OS not fashing vbmeta.img and it works.
If you already have the bootloader unlocked you can skip to step 6.
Make sure OEM Unlock is ON in developer settings;
Turn off the phone;
Use vol down + bixby key + usb cable plugged to a pc to start the phone in download mode;
Long press vol up then confirm you want to unlock bootloader (this is needed one time only);
5.** Please be aware all your data will be erased including internal storage and phone will reboot!!**
Let the phone boot normally, pass the setup and connect to internet (wireless or mobile data) in order to unlock RMM;
Make sure OEM Unlock is ON in developer settings;
Turn off the phone;
Use vol down + bixby key + usb cable plugged to a pc to start the phone in download mode, short press vol up to confirm you want to go to download mode;
10.** If by any chance you see RMM state=Prenormal or KG state=Prenormal, redo from step 5!**
Download appropriate TWRP .img file according to your device
