Hi,

To get Root, you would need to reset the device.
Search info about your model for the future, now isn't possible, otherwise you'll loss the Data.

• Open Opera Mobile and LogIn using your liudka Opera Account
• Sync everything

Once done
Use a Browser that allows Chromium Extensions, if your Opera 36 doesn't, try Chrome.
You would try the steps on another computer you have access, then Export the Bookmarks.

• LinkClump it's on Chrome's PlayStore
• Follow the previously mentioned steps on how to configure it
• Go to Sync.Opera.com
• History
• Follow the previously mentioned procedure to use it

You need Root, otherwise there's no access.

You could enable Sync, then from the same site, Sync.Opera.com, go to History and do the LinkClump Steps.
After that, search on the Bookmarked History Links and try to recover them.

Hi, @zalex108 !

I will repeat steps from you advice.
Please, check is it correct and explain to me some things more detailing, if I will ask it.

So,
Part I.

1. I need root my smartphone.
2. I need open Opera on my smartphone-> Create account-> Log in-> Enable "Sync everything".
3. Then, I need go to: Sync.Opera.com-> History.
4. Then, I need search for LinkClump Extension.
   What is it? Where is it located?
   Can you attach a screenshot, which can explain where is located LinkClump Extension?

For the moment,
You would try this:

Click above

Then,
You would share the Tabs to yourself on TG or somewhere to save them.

I will start the topic about this problem.

Can you help me find this files, please? Where is stored this files (folders/databases...)?
And what is exact name of this files ("current session" or something else)?
I am trying to find it, but I can't yet.

What have you tried so far to find the answer for your question?

@liudka
Was you using Opera Sync?

I didn't use Opera Sync... And I didn't use any Chromium on Desktop...

Answering your question,
If your device is Rooted, you would find that files but not sure whether they have a .bac file to recover the Data.

@liudka You need to update Opera to the current version.

I updated Opera to 61 version, but it didn't work... I can see only 10 last closed tabs yet...
I will waiting an answer from miyukiwork.

Hi,
Was you using Opera Sync?
If so, and you use any Chromium on Desktop, search for LinkClump Extension, change the trigger key to C, and select to Bookmark Links.

Then, go to Sync.Opera.com, Tabs.
If they are still not deleted, just Click C, select the Mobile Tabs link, and they will be Bookmarked.
At least you would recover them.

You can use this method to back up and to Bookmark periodically.

Look at https://help.opera.com/en/latest/crashes-and-issues/, files should have the same name.

Some files are JSON and SQLite.

"Off Topic Tip"
Follow the Signature's Backup | Reset link.
Take the opportunity to start a Backup plan and even create a Template Profile.

SyncBack | Synkron helps.

Windows 7 (x64)
Opera | Back up | Reset

I don't the answer but I believe that you can find it if you do a search. Opera is based on Chromium, so look for Chromium file structure.

Give me, please, information which I asked.

You wrote:

• If you go to the tab menu, ... menu, then there is recently closed tabs. Do you see your old tabs there?

It works for few last closed tabs only. But it doesn't work for all (50+) closed tabs.

So, I urgently need information:
Where is stored information about current session/opened tabs on android (file/database/etc.)?

I know, that you/developers know it.

If Opera has restriction for count of opened tabs/memory for opened tabs on the one moment, then Opera mustn't open a new tab.
And Opera mustn't close, without warning, opened tabs, which opened earlier.

Please, give me information, which I asked you.

We are sorry about the experience. If you go to the tab menu, ... menu, then there is recently closed tabs. Do you see your old tabs there?

Which Opera version is the problem from? We have fixed many tab related bugs in the latest version.
