Downgrading android 12 to 11 on a samsung galaxy s10e and installing /e/

Je crois avoir lu

samsung/beyond0ltexx/beyond0
11/FP1A.200729.12/G970FXXSEFUL1
user/release-keys

Est-ce une bonne idée de confirmer que le téléphone fonctionne avec cette ROM stock ?

Je ne comprends pas.

Oui mon téléphone fonctionne, pourquoi ?

Afin de vérifier que la nouvelle modification d’Android 11 que vous avez effectuée jusqu’à présent a correctement et effectivement changé le téléphone par rapport à l’Android 12 signalé. :slight_smile:

In order to check that the new modification to Android 11 you have done so far has correctly and effectively changed the phone from the reported Android 12. :slight_smile:

Oui mon téléphone fonctionne normalement…

Bravo ! Félicitations ! Je pensais que cette partie serait la plus difficile. J’espère que l’installation de /e/ se passera bien. C’est d’autant plus difficile que /e/ ne fournit aucun guide en langue française.

Bravo! Congratulations! I thought this part would be the hardest. I hope the /e/ install goes well. It is extra hard that /e/ provides no guides in the French language.

Merci mais finalement l’installation de /e/ est la plus dure…

Je viens de réessayer en rajoutant l’étape 4 mentionnée par piero

J’ai eu à nouveau un “fail” sur odin.
Sauf que là en voulant quitter le download mode j’ai le message

“an error has occured while updating the device software. Use the emergency recovery function in the smart switch pc software”

Du coup, là mon téléphone ne fonctionne plus et je ne sais pas quoi faire :frowning:

Je parle anglais mais quand c’est technique comme ça j’ai du mal à tout comprendre :frowning:
Surtout que dans le tuto, ils parlent d’adb, fastboot, heimdall …

Mais pas de TWRP ni vbmeta… Je désespère clairement…

Je vais chercher mais je pense qu’il y avait des difficultés similaires avec cette nouvelle génération de Samsung. Pouvez-vous envoyer une image de l’écran du mode téléchargement, cela pourrait montrer les verrous restants.

Avant de modifier le téléphone davantage … pendant que le téléphone est encore en Samsung/Android, je pense qu’il est bon de s’entraîner à appuyer sur tous les boutons pour passer en mode téléchargement et du mode téléchargement directement au mode récupération (c’est-à-dire ne pas permettre le démarrage du système). Les pressions officielles sur les boutons sont au pied de Info about Samsung Galaxy S10e - beyond0lte.

I will search but I think there were similar difficulties with this new generation of Samsung. Please can you send an image of the Download mode screen, this might show any remaining locks.

Before altering the phone any more … while the phone is still in Samsung/Android, I think it is good to practice all the button presses to change into Download mode and from Download mode straight to Recovery mode (that is do not allow boot to system). The official button presses are at the foot of Info about Samsung Galaxy S10e - beyond0lte

Cette page https://doc.e.foundation/devices/beyond0lte/install comporte 9380 mots, je ne peux donc pas la traduire en une seule fois. Je vous suggère de faire une bonne préparation en traduisant la page sur un document sur votre PC. Ce travail vous permettra de vous familiariser avec la méthode /e/.

This page https://doc.e.foundation/devices/beyond0lte/install is reported 9380 words so I cannot translate in one go. I suggest you do some good preparation by translating the page on to a document on your PC. This work will help you become more familiar with the /e/ method.

Odin

J’ai eu à nouveau un “fail” sur odin.

Veuillez décrire ce que vous avez fait pour provoquer cette erreur.
Please describe what you did to cause this error.

Ok ! Alors je continue en français, @aibd tu peux peut être écrire en anglais uniquement si tu préfères …

Voici l’image de mon erreur (prise sur internet). Si j’ai bien compris je dois réinstaller android 11 c’est ça ?..

J’ai compris comment lancer le recovery mode. Mais je reçois l’erreur “fail” sur Odin même en désactivant “l’auto-reboot”. Donc l’erreur ne provient pas de mon incapacité à cliquer sur les boutons je pense :slight_smile:

Voici ce que j’ai fait exactement pour obtenir les nombreuses “fail” erreur sur odin.
Si j’avais su j’aurais jamais essayé d’installer /e/ sur un s10…

“fail” à l’étape 11, peu de temps après avoir cliqué sur start.

Merci pour ton aide.

J’ai inclus une traduction au cas où mon français ne serait pas assez bon. Je peux faire les deux, mais je suis plus lent en français !

I managed reinstalling android 11.

For others, while on the blue error screen, press and hold volume down + power until black screen appears. Then release.

You get the blue screen again (normal), click once on volume up (nothings happens, also normal).

Go on Odin and flash again the stock rom you need.

Bravo !

I am glad you recovered!

I wanted to see the situation of your phone when it was stable. I hope you will press buttons on a stable phone because it is different from the S7.

I hope you will do the preparation I suggested!

@piero !! Only if coming from full stock firmware

Let’s be sure ! :slight_smile:

Every time you do a Factory reset you must go back to Make sure OEM Unlock is ON in developer settings

Thanks. I perfectly know the buttons I need to click to enter download mode and recovery mode…

I have already read many times the /e/ tutorial.
However, it describes only how to use Heimdall and I am trying to do it with Odin.

The tutorial describing how to use Odin, is not about the S10e and doesn’t work at all.

Until now, only what Piero said was supposed to work but it failed again. I have no idea why.

Are you saying that my stock rom is not good ?

Pour Piero, tu disais que peut être mon Odin était trop vieux mais j’ai la 3.14.

One reason for the error

“an error has occured while updating the device software. Use the emergency recovery function in the smart switch pc software”

is that you had interfered with the device (good or bad I do not know) then you allowed “Boot to system”.

Once you start to interfere you must see it through.

I am not familiar with Odin. I would not like to guide you on that.

I was not saying your stock ROM was not good; I was asking for a view of your Odin mode Download mode screen to look for any existing locks!

[HOWTO] Install /e/ on a Samsung smartphone with Windows easily is not very much wrong, but there are different steps for this device.

Notice how in @piero’s XDA link [ODIN (Windows)] the author corsicanu reminds us to keep watching the Odin mode screen.

I thought you asked for a picture of recovery mode (not download mode). Do I need to supply something else for you to check something ?

Why does it mean by “keeping watching the odin mode screen” ? I can’t find where he highlights that on the link.

Sorry, not exact words … he says (and this is the section already highlighted by @piero)

Instructions: {then open spoiler}
Odin (Windows)
CLICK TO HIDE
Prerequisites: [Samsung USB drivers], Odin v3.14.1

First {where are you in the cycle?} … you want to check Odin screen to see: Are you RRM? Are locks OFF?

five “Let the phone boot normally, pass the setup and connect to internet (wireless or mobile data) in order to unlock RMM”.

eight … then …
If by any chance you see RMM state=Prenormal or KG state=Prenormal, redo from step 5!

{Requires you to look at Odin mode screen}

Start - once you press start grab the phone and press vol up + bixby + power to force it boot straight in TWRP after flashing

Before you start, notice that you can use his linked and here Odin v3.14.1.

This is why I suggested a practice Move to Recovery because it looks is if it is more difficult than previously if you are not able to “Do not reboot”! :slight_smile:

Sorry I have no idea what it means if you could translate that for a newbie…

I’ll try with Odin 3.14.1 instead of 3.14 but I have not much hope as I have been trying at least 50 times…

Odin mode screens are difficult to read; show me the image and I will read it!

I am not sure if it is you or I that don’t understand… But Odin is failing way before any reboot is happening.

What is Odin mode screen ? Is it entering the “recovery” mode screen (modified with Odin) after flashing successfully TWRP ?

I am stuck way before that… The only screen I see is download mode, my phone never reboots.

I know ! :slight_smile:

I want to tell you I am trying to say this with kindness! :blush: All I can do is show you the instructions, you need to prepare then do it right once you get there !

@aibd practice

The Odin mode screen is the Download mode screen. Please avoid racing ahead of me. We are still doing the prerequisites, not doing anything to the phone yet, we want it to stay a stable Samsung/Android until we start correctly.
