![]() ![]() Unlike the EPROM in Flash memory, the SD Cards aren't really designed for many write cycles, so as time goes on you will find the card wearing out sooner than usual.ĭevice will not be as stable. The phone will not be able to function if you remove the SD Card, since the 2nd ext partition is now used by the phone as if it was part of its internal memory.Įxtra wear and tear on the SD Card from excessive writes. Slower cards will cause delays in apps starting up, for example. Speed rating of the SD Card will play a large role in the system's overall performance and stability. SD Card needs to be re-partitioned in a very particular way (data will be lost during partitioning, so back it up.) However, as with most such solutions there are many cons to be aware of. This trick does free up a portion of internal memory for use as RAM. Namely, all 3rd-party downloaded apps, phone's cache, and in some cases app data and dalvik-cache.Īlso keep in mind that as with all custom ROMs and kernels, this needs to be built for a specific device, so you will need to find a ROM with built-in Apps-to-SD support for your specific handset. This is where you re-partition your SD Card to have an Ext2/3/4 partition after the main Fat32 one, and then use a custom ROM/kernel combination that allow moving certain parts of OS to that partition. I think you are referring to a hack commonly known as "Apps-to-SD" (a.k.a. If you want to move your data (pictures, videos etc) you can go to settings>storage>SD card>more and you will have there option "migrate data" hit it and let it go. If you want to use only half of SD as adoptable then use this command " Is replaced with result from previous command, in some cases there is ' to list the disks available, the result should be something like " ![]() " to make sure phone is detected, then type " Open terminal or command line on PC ( make sure you have ADB installed if not then download minimal ADB and fastboot, you can find it on Google click ) type command " Make sure USB debugging is enabled in developer options under settings and then connect your phone to PC via USB cable. NOTE all data on your SD card will be lost. Most of OEM's doesn't offer in gui option for adoptable storage. Scan the whole userdata.img with extundelete (linux) Once you have a ext4 disk image of userdata: Switch off device, remove battery (if possible)ĭo a read back of userdata partition (SP Flash Tool) Sudo apt-get install android-tools-adb extundelete testdiskĪdb shell chmod 0755 /data/local/tmp/mtk-suĪdb shell /data/local/tmp/mtk-su -c "cat /dev/block/dm-0 2> /dev/null" > userdata.img I still have contacts my messages and my settings, just that everything that was accessible through the file explorer has disappeared. However, when I woke up the next morning, all my data on the internal memory was gone. Nothing happened that day, except that I couldn't access any of my WhatsApp images through WhatsApp(they were still accessible through the gallery). I assumed that the first two were leftovers from the TikTok app and the third was mere thumbnails. One was a folder with Chinese name, one was a folder called ByteDance and one folder called Thumbnails. Yesterday I connected my phone to my PC over mtp and found that there were certain leftover folders on the internal memory. I recently uninstalled the TikTok app from my phone. How can I create an image, a data dump of my entire internal storage that i can later analyse for my data?Ĭan I do it with an unrooted phone? If not, how can I root my phone with ADB?Īm I going about this right? Is there a better, easier way to recover data that I should use instead? My next step would be to use Wine to run KingoRoot on my machine and try to root my phone that way. I have Ubuntu on my PC and there is not KingoRoot for Ubuntu. I assumed this is because my phone isn't rooted? I tried to root it with the KingoRoot apk but that didn't work. To try create an image of the entire internal storage so I can analyse it using PhotoRec. Enabled USB Debugging and OEM Unlocking from Developer options in my phone. None of them worked.ĭecided to go more technical. Tried using photo recovery apps available on Play Store. I've been googling and following stuff I get from the internet(including Stack Overflow). I have a Lava Z90 phone and I do not use an external SD card, so I must work with my phone to recover all data. I will explain the events leading up to this in a separate paragraph All my photos, my music, my PDFs, audio recordings, everything. Yesterday, I suddenly discovered that I had lost all the user files on the internal memory of my android phone. ![]()
