Restore deleted Telegram messages, medias and files from groups

There's not telegram API method for this, we need to call MTProto methods to retrieve messages from the "Recent Actions" (Admin Log) since deleted messages (and medias) gets moved there for 48 hours before the permanent deletion.

from telethon import TelegramClient, events, sync
from telethon.tl.types import InputChannel, PeerChannel
from telethon.tl.types import Channel
import time

# Get your own api_id and
# api_hash from https://my.telegram.org, under API Development.
#  or from https://tjhorner.dev/webogram/#/login
api_id = API_ID
api_hash = API_HASH

client = TelegramClient('session_name', api_id, api_hash)
client.start()

group = client.get_entity(PeerChannel(GROUP_CHAT_ID))

#messages = client.get_admin_log(group)

file1 = open("dump.json","w") 
c = 0
m = 0
for event in client.iter_admin_log(group):
    if event.deleted_message:
        print("Dumping message",c, "(", event.old.id, event.old.date,")")
        file1.write(event.old.to_json() + ",") 
        c+=1
        if event.old.media:
            m+=1
            #print(event.old.media.to_dict()['Document']['id'])
            client.download_media(event.old.media, str(event.old.id))
            print(" Dumped media", m)
        time.sleep(0.1)

FAQ

How do I run this?

Please check https://docs.python.org/3/faq/

Is there a way of restoring the data dump.json and images into the original group? I have access to the original user account that the messages originated from.

It may be possible to "forge" a new history with a bot, but I don't think you would be able to post a message in the past

OK, So what I understand you are you saying that you could have timestamps from when the original post was made, but they would be posted on the current timeline. Could you recreate a group history in another group with some sort of import and merge recovered data with current history?

@Dawe24 Are you sure your api_id, api_hash, group id and phone number are the correct format?

I invited my bot to the group, gave it admin rights, and gave the script my bot token. I am sure you can understand that I am a bit reluctant to give an unknown script (to me atleast) my phone number to log in, that it could do basically anything it with my user. So I gave the token of my bot.
And I think I put the right api_id and api_hash, just like how it was on the my.telegram.org site. Imgur pic
I had no idea how to get the group id, so I exported the group chat history to a json file, and at the beginning of that file, there was the id.

If I try with phone number, how to format it? Our format is +36 XX XXX XXXX

Thanks in advance.

@Dawe24 The group id you can get here https://tjhorner.dev/webogram/#/login and click on the group. The phone number format looks ok, but without the spaces.

Thank you guys, worked just fine. Now I am also interested to putting these messages back to the group/new group. So I will stick around to see if it goes somewhere. Also a friend of mine wrote to Telegram Support in this matter, maybe they can restore it from the json, or somehow from the Recent Actions. Again, thank you.

You're welcome. Yes, it would be great if a restore could be done. I'm hoping @avivace will have some advice.

from https://my.telegram.org, under API Development.

or from https://tjhorner.dev/webogram/#/login

Get your GROUP_CHAT_ID from https://tjhorner.dev/webogram/#/login

when click on the chat

and put them inside the variables down

6. finally run in the terminal

STEPS TO RECOVER ALL THE MEDIA AND MESSAGES DELETED FROM TELEGRAM CHAT:

[STEP 0]
You need to have python on your machine https://docs.python.org/3/faq/ you can check if you have python using this command:
python --version

[STEP 1]
Create a folder (to save the backup inside it) using the normal way.
NOTE: OR using this command:mkdir backup_will_be_inside_me.

[STEP 2]
Copy and Paste this file inside the folder you created in [STEP 1] backup_will_be_inside_me THEN rename the file to backup_script THEN open it cause we need to change some lines (it should be with extension .py)

[STEP 3]
Open your terminal and install telethon using this command:
pip install telethon

[STEP 4]
Get your own api_id, api_hash and group_chat_id and put their values in the code below the sentence THE_CODE_START_AFTER_THIS_LINE:

A. How to get your own `api_id`, `api_hash`:
    1) Go to `https://my.telegram.org` and log in.
    2) Insert your phone number `+XXXXXXXXXXXX`.
    3) Insert the code you received in the Telegram application.
    4) Click on `API development tools`.
    5) Now you will find your `api_id`, `api_hash`.
    NOTE: or from `https://tjhorner.dev/webogram/#/login`.

B. How to get your `group_chat_id`:
    1) Go to `https://tjhorner.dev/webogram/#/login` and log in.
    2) Insert your phone number `XXXXXXXXX`.
    3) Insert the code you received in the Telegram application. 
    4) Click on the chat you want to recover messages from it (like you want to send a message).
    5) Click on the chat information.
    6) Now you will find your `api_id`.

[STEP 5]
Finally, recover the deleted media and messages:
1) Open the termenial inside the folder backup_will_be_inside_me (by hold SHIFT + Right-Click THEN pick Open Powershell here).
2) Run the code in the file backup_script.py by using this command:
python backup_script.py
3) Insert your phone number 00XXXXXXXXX.
4) Insert the code you received in the Telegram application.
5) NOW all you need to do is to wait till the process of recovering deleted media and messages is done.
NOTE: The process needs time depending on the size and the number of the media and the messages you will recover (look at the date to know where the process reaches).

=> Inside the folder `backup_will_be_inside_me` you will find all the media you lost (Images, voices, videos, etc).

=> Inside the file `dump.json` you will see the text that you deleted from the chat.

@dkovacs24 What's the TG-Support's answer?

@Enough7 Nothing. I also wrote them a couple months ago on another matter, twice, zero replies. In their defense, they are a volunteer support service, but zero answers, not even a "We got your message", is a disappointment.

Thanks

Does one have a script for converting the dumped json file into a more chat-like looking text?
From my experience, the "recent actions" section showed only the latest portion of the deleted messages. However, the script, after downloading this portion, automatically proceeded to the other, previous portion, which was not observable in Android and PC client. The overall volume was some 6 Gb. The messages from some 25 days (preceding the latest portion and, correspondingly, finalizing the earliest portion) were not downloaded because the claimed 48h period for copying the deleted messages turned out to be only some 24h (maybe precisely 24h), which is a certain nuisance.

TypeError: bytes or str expected, not <class 'int'>

@AnarialPrescott At some point the program gave telethon an int(eger) instead of a str(ing) or bytes.

@Enough7 thank you! can you please tell me at what point this could have happened and how to fix it?

@AnarialPrescott Okay, just because you asked that nicely :).
The error is raised here.
Before the error occurred this line is executed.
That line is located in a function called edit_2fa.
It looks like that code segment is trying to change your password and fails because your E-Mail-Address is not confirmed.
So it is probably related to two factor authentication, try turning it off or test it with a different account if possible.

@Enough7 Thank you very much for your answers! But, unfortunately, even with two-factor authentication disabled and with another account does not work and still the same mistake(
But still thank you very much for helping me!

@AnarialPrescott You can contact the developers of Telethon here
