File recovery on internal memory of Huawei P9 after MTP bug - Android Q&A, Help & Troubleshooting

Hello developers,
I recently joined this platform because it actually looks like this forum is my last hope. A few weeks ago I lost lots of new holiday memories while I attempted to move files on the internal storage of my Huwei P9. The mobile was connected via MTP to a windows 10 PC that I wanted to use to organize pictures. The files of interest have been moved within the camera folder into a new subfolder and got lost due to the MTP bug.
I tried a few simple free recovery tools, such as recuva, but without success. Those of the authentic and reliable recovery companies are either not capable of recovering the data because of technical reasons or they make non-economic offers with little chance of success at the same time. I have avoided to generate new data on the phone and turned it into flight mode, but I have not been aware of the trimm process, so I did not turn it completely off.
Do you experts see any chance to recover the pictures? Which steps would you recommend? I thought about rooting the phone followed by raw scan by DiskDigger.
I appreciate every recommendation, thanks a lot in advance!
Greetings

[Q] How to recover Lost Files from internal memory?

What I lost:
The first TKD-sparringsmatches (ever) of the 7yo son of a friend of mine were succesfully filmed with my SGT 10.1v. The boy performed phenomenally: Despite being a debutant, he won 3 matches in a row and won the golden cup, abroad!
How It happened:
At home, I eagerly connected the SGT with the USB-cable to a Windows XP PC, selected the recorded media files in the DCIM/camera folder and choosed "MOVE". The transfer started, with placing the files in the "My Documents" folder on the PC. Because that wasn't my preferred destination, I canceled the transfer...
Then the disaster occured: The files disappeared !!! They no longer existed on the Tab.
Futile rescue:
I immediately started an obsessive search in Google, determined to find a solution to recover these lost files. In the meanwhile, I made sure to put nothing new in the tab's internal 16GB memory.
Now:
That happened a week ago, and I'm devastated. The only way, as far as I know now, to make a beginning in recovering the files would be to ROOT the device and install special software e.g. Hexamob, but that hasn't even been developed for Android Honeycomb.
Help:
Therefore, I can only hope to get an answer here, to help me in my moment of total desolation...
isent it possible to use a recovery tool on your pc and connect the tab with the usb cable and select the drive that way?

That would work if the internal memory would be recognized as an SD-card. But none of the appropriate 'undelete' programs that run on windows find the external flash drive

Moving to General
I've successfully used software to recover missing data from a damaged sdcard. I don't remember the name of it as I'm at work and the software is on my home computer, but once I get home tonight I'll be sure to look and let you know.
EDIT: Found it! It's called PhotoRec: http://www.cgsecurity.org/wiki/PhotoRec I was able to use it and it recognized my sdcard when my computer wouldn't. Hope it works for you, good luck.

Thanks varelawarfare but PhotoRec is just another example of software that rus under Windows and therefore doesn't recognize the internal memory of het SGT, it doesn't find the drive.
So it looks like the only way to recover the mediafiles would be an application that runs on the SGT 10.1v, inside or outside Android...
Were you ever able to find a solution?
I just did the same thing. Accidentally dragged my DCIM folder to another folder when in Windows, and it seemed to drop all of the photos/videos. I verified this by running an adb shell after.
The only 'recovery' apps don't seem to work on Honeycomb still, and none of the Windows or Linux file recovery programs will see the filesystem.
Just looking for ideas to get them back if possible at all.
Stock Honeycomb 3.1 on rooted 10.1
I was having similar issue last time, you may follow the step by step guide that helped me last time

hope this helps.

[Q] Need help for decrypting Whatsapp conversation from the lost phone

Hey all...
This is my first post on this forum and I hope that this is the right place for my question.
I lost my phone, but I was able to find some data that I have copied to the PC not so long time ago. The thing is that I had some important dates and conversations on whatsapp and all what is left on my PC are db.crypt7 files which I can't open. I red a few guides about it, but some kind of key and software is required in order to open those files and I am 100% noob regarding things like that. So my question: Is there any chance to decrypt those files I have from the whatsapp folder of my lost Samsung Galaxy S2, or all hopes are lost? Phone was not rooted and all I can find are those few db.crypt7 files.
Thank you in advance!

[Q] Phone Memory partially pin locked?

Hey there,
Recently my Galaxy S3 fell to the floor and the display broke. Now I'm desperatly trying to recover all of my data from the internal phone memory. The memory has 16gb in total, but when i copied it to my hard disk drive i could only copy 2gb. It seems that the camera folder (DCIM) is the only folder taht has been completely restored. Is it possible that all other folders are pin locked? Or is it more likely that the storage is broken? Anyway, what i really need to recover is the phone calendar, since not all entries had been synced with google calendar. I can't find ANY calendar file on the internal storage, and i've searched most common places (data/data/android.provider.calendar etc.). My research showed taht the only way to access the phone with recovery apps is when the debug mode has been activated. Since the display is broken there's no way for me to activate it.
In short, my questions:
- Why can I see only some of the internal storage? (2/16GB) -> broken or locked?
- do you have any idea how i can restore the phone calendar since there doesn't seem to be any calendar file?
- is there a way to activate the Debug mode with a broken screen?
I consider buying a new display just to be able to access the files. But since i don't want to waste any money i need to be 100% sure that this works. But the fact that i've only been able to copy 2GB from the internal storage and that i dont seem to find the calendar files makes me doubt that this will help at all.
additional info: I'm accessing the phone via USB cable without a sim card.
Thanks for any help.
Edit:
I also tried connecting the phone to Kies (i never used Kies before) by activating the "download mode" on the phone by pressing some buttons at the same time when turning the phone on. Kies seems to recognize something but it just keeps on saying "connecting to phone..." for hours. I take this as another indication that the phone might be broken beyond the display.
Edit2:
I found this:
inaccessible folders: folders you won't see due to lacking permissions, e.g. those in /data. To protect your apps' data, those folders belong to the corresponding application, and are only accessible by the app (in the context of file-permissions; please see the tag's wiki for closer information on those). To make those visible, you need root access on your device, and a file explorer supporting that (e.g. ES File Explorer)

Is there any way i can get root access to the phone with a broken display?

Huawei P9 Single SIM Bricked - DLoad Folder Stuck on Internal

Hello. I got an interesting problem happening with my Huawei P9 EVA09 I believe the EVA is.
Anyways a few months back I was attempting to get the Android Update off of Huawei's web site for my phone. During the steps, I either missed the note or it was never mentioned, to put the DLoad Folder and ZIP stuff on the SD Card and I copied the files onto the Internal Drive Instead.
Now whether I downloaded the wrong file or I was linked to the wrong file, my phone failed the Flash/Update about like 10-25% saying it was not compatible or wrong version (again, we're going a few months back in memory here)
I learned that rather than cancelling the process and going back to the regular Android, it just screwed the whole phone up and is stuck in an infinite boot loop.
Huawei's Desktop app you connect with the phone won't help
Recovering by downloading the latest version via WiFi on the P9 Fails to get the Package Info, so that's out of the question.
Wipe Data and Factory Reset fails at 0% with an exclamation mark in less than a second.
I also spent days searching the net for solutions but every search just brings up the same solution:
Get the correct DLoad/ZIP for the model, copy it to the SD, then boot the phone with the key presses that start the flashing process.... Problem solved.
But it's not because every time I do this, my phone finds the one on the internal storage and loads that before going for the one on the SD Card, and I have no idea how to gain access to the internal drive to remove the DLoad folder to fix my phone.
I have been primarily a Windows Mobile user for the last number of years, but my 950XL has been giving me problems with my SIM card flaking out every so often, requiring a reboot. I got the P9 essentially for free when I upgraded my plan with Vodafone Aus. So my experience with Android and these sorts of messes is limited.
I'm used to fixing and figuring out Windows Issues since Windows 3.11.... But this issue with my P9 has got me stumped. After searching online on and off for the last few months, I figured this is my last hope to ask the experts here and hopefully find a solution.
I got the right Flash/ROM/Recovery for my P9 all ready to go and load from the SD, followed videos, got it all sorted.... I just can't get it to work with the other files stuck on the Internal Drive and I need access to delete the folder.
But I'm in a Boot Loop.
By the way, it's a Locked P9 from Vodafone Australia.
Any assistance will be appreciated greatly. It's a nice phone, but it was two Android Versions Out Dated and I didn't think the Files from Huawei's site would have messed it up so badly. If this is fixed, I'll leave it at the original version until I need to replace the P9. Sucks, but I would rather that than a bricked device.
I'm back on my 950XL for now and was going fine so I put this problem on the back burner. But now the SIM card is messing up in the 950XL, requiring a restart every day or two. So now I need to try and fix the P9.
Thanks in Advance.
TL;DR
I need to gain access to the Internal Drive of a Locked P9 while stuck in a Boot Loop so I can delete the DLoad Folder located on the Internal Drive.

How to extract Whatsapp Key from an SD-card install?

Dear all,
Though I'm kind of a beginner, I have made much progress backing up and decrypting Whatsapp messages from my old Android phone. However, there seems to have been an even older installment of Whatsapp running from an SD-card on the same device. There are Whatsapp-database files there, but I cannot find the decryption key.
I have tried many ways of going about it:
1. Exploring the root of the SD Card does not lead anywhere.
2. When I use Whatsapp-Key-DB-extractor by Tripcode, it only extracts from the phone's main drive.
3. When I transfer the older databases from the SD-card into their corresponding folder on the phone (either alongside, or replacing them), and then run the Extractor, again no success.
4. In the Apps menu of my phone Configurations, when I go to Whatsapp, the button "Move to SD-card" is unavailable. I figured this may be because only older versions of Whatsapp were able to move to an SD-card and run from there.
5. I downloaded and tried to install older versions of Whatsapp through APK-mirror (with the objective to consequently see if I can move it to the SD-card), but all of them ended in "unable to install"... And anyway, the oldest version available on apkmirror is not as old as the databases we're talking about (which are from June-July 2014).
6. Finally, I noticed that part of the Whatsapp-extractor's procedure is to revert to an older version (2.11.431) and back, so I tried interrupting the process before it sets the new version back. To no avail.
Can anyone come up with a workaround? Those messages are quite precious diaries of those days. My phone is an Experia Z (Model D5503, Android 5.1.1), but it has been stuck in a BootLoop since a very long time. I finally found the time and energy to sit down and see if I can learn how to get the most valuable information out of it after all, and after many, many hours and lots of patience and steady-handedness (the rebooting seems to occur with movement), I decrypted the database from the phone itself. Now I really cannot accept defeat in front of an even older treasure
Oh and post-edit: The databases from 2014 are crypt7. The ones that I DID extract succesfully are crypt12.
Best,
Publo
