Data recovery?

Hi, I had several pictures that I took for my friend, but before I got a chance to send them, my device (XDA IIs) performed a hard reset.
Is there any way to perform a file recovery on the device?
I understand that the memory is shared between storage and running apps, so I havent used the device for anything after it turned back on, so I think there still is a chance of the pictures being on the system.
If there is any way/ any programs that would do it, I would greatly appreciate your suggestions.
Thanks,
RM

Alright, I think there might be a solution
if I use pmemdump of the flashram (or user ram?!), and then raw-write that onto an SD card, I can then use something like Ontrack Easy Recovery in RAW recovery mode.
My next problem is: What is the address of the start of the memory where the files can be kept? And whats the length of memory that I need to dump?

no ram cant be undeleted
when ram is reset the data is lost forever
just lake the ram on your pc if you reset it without saving it's lost

Ok. I thought it was flash ram instead of regular ram...

the only part which is flash on a himalaya with 2003
is the dir called storage
and the extented rom

my RAMDISK lost, why?

I cook my own ROM of Hima WM5, based on llsbasha and C_Shekhar.
after several times, I decide using 64M program, 32M RAMDISK, 32M PagePool. At First, I success, but the second time, when I open memory from Start --> Settings, my Hima says no storage cards (my sd card ejected)
RAMDISK DISAPPEARED
How can I find it back?

I don't know what happened to your storage card but I think I know for the ramdisk.
Well, I suggest that you hard reset your xdaII and do not install ramdisk software to increase ramdisk size. Based on my experience, after I installed the ramdisk 64, the size increased to 90+ but everytime I soft reset, the data I saved in it gets lost.
After hard resetting, the ramdisk came back to normal 30+, I found the lost previous data intact though.

Can you list out the steps you are taking for the configuration you are trying to finalize? Because if you change the configuration after flashing the ROM (or on a working ROM) the settings are likely to disappaer after soft-reset).

This will only happen if your battery are old and need to change.. Some how it will not keep the RAMdisk and only by another flash will bring it back.

S710 hard reset recover files ???

He guys,
I've updated a S710 for a customer of mine but he forgot that he had some notes on the internal memory that he really needs.
Anybody know a way to do this. Already tried a normal data recovery program but this doesn't see a smartphone....)-;

I'm afraid that hard reset formats the nand flash and all data is really lost.
I'm not sure though. You can try to use the "pdocread" program to dump the windows and extrom partitions and see if you can still find customer data in them. Check out the Vox wiki for a howto.

Don`t bother in that matter. If notes was in internal memory, then after reset is lost for good, taft.

[Q] HOXL Data Recovery

Hi fellow xda-members,
I recently wiped my One XL 32GB with the HBOOT Factory Reset,
didnt know that it wipes the internal storage aswell...
Needless to say that I work with the phone and the data is priceless...
I already tried to pipe the whole mmcblk0 via netcat, which worked fine.
All but the FAT 25GB partition are getting recognised via testdisk.
Did 2 dd's, so I got 2 raw-images of mmcblk0 and mmcblk0p36.
None of the recovery tools (Recuva, testdisk, @active, pc inspector recovery, etc.) did find any files.
The Partition wasnt formatted and also wasnt mounted yet, there should be no changes made from android since the wipe.
If I open the mmcblk0p36 via hex editor, its complete null.
The mmcblk0 image has random data all over the whole area,
but also mostly null (estimated 80-90% null). The internal memory was almost full,
about 22/25GB, so there are 3 options:
1.:The HBOOT Factory Reset doesnt delete just the FAT, but also nulls the whole data. (Which would be weird, because the reset took 3-5 seconds, I doubt it can null 25gigs in 5 seconds ;D)
2.:The chip has a kind of "fast-wipe" option, which makes it possible to null 25gb in 5 seconds, never seen this before, but who knows
3.:The data wasnt nulled, but dd doesnt read 1:1, which would be also weird.
Is there any app/commandline tool for android to directly check
whats on the specific part of the internal storage?
Or are there ways to access the memory directly to get
a exact image of the internal storage for recovery other than "dd if=/dev/block/mmcblk0"?
If none of the above, is there a chip-recovery expert that can recover the files with jtag/advanced hardware?
Thanks for all replys

Was the phone modified? If so, the factory reset in the bootloader doesn't just wipe the data, but it completely corrupts it, that's probably why you're getting no data show up with the recovery tools you're using.

Yes, the phone is rooted and s-off'ed,
I personally didnt change the partition alignment,
but updated the hboot from somewhat 1.09 to 2.18 a few days before.
Has the layout been changed in the past?
And, if the data was really corrupted, what to do about?
Is there any chance to recover the files?
thanks

I don't see how the partition alignment is relevant, but no I don't believe it's changed. I don't think you're going to have much luck in recovering your data, if all those recovery tools aren't yielding any positive results.

If the partition alignment has changed, the hboot factory reset could possibly null more/less/other/the wrong ranges of memory while wiping.
I have new results:
I've checked the fresh raw dumps with a hex editor, finding out the range of mmcblk0p36, the internal sdcard only contains nulls.
Thats why every recovery tool doesnt gather any file.
I know that dd copys every bit 1:1, so I am out of luck with dd.
Does someone have experience with jtag raw data recovery?
Is there a way to gather other/deeper data with jtag?
Thanks

Question Headunit Factory Resets itself (how does the storage work?)

My UIS7862 based unit (Atoto S8 Ultra) started a nasty habit of randomly hard resetting itself every few weeks. Once it happened even while driving! It was working fine for 9 months but once it started, it has been a pretty consistent problem.
Support has not been helpful, I'm trying to understand if this is hardware or software. I already tried leaving out third party launchers, and keeping applications down to a minimum in case any of that might be a culprit (sticking to just installing basics like Spotify). Still reset itself after a few weeks.
Support has sent me firmware updates which did not help, and obviously I also tried doing a factory reset myself (in case something needed to be cleared out and start over fresh). I was starting to think perhaps there's a hardware problem that is shorting out the storage chips or something. But I just noticed today while poking around that the internal storage still has remnants of my first setup. I see folders from apps I have not installed since before the first reset, and even some media that I downloaded and screenshots I had taken!
Please excuse my lack of experience in understanding this, but I understand that data and memory/storage are different partitions. So it seems only data is being reset, but not memory/storage, since my files are still there from many flashes and factory resets ago.
Does it make sense that a hardware fault would ONLY be resetting the data partition but not the rest of the memory/storage? Or is that a logical partition, which would imply that the problem might actually be software related?

to me it sounds wrong. on android usually only a single partition is writeable. it should never factory reset itself.
I could imagine a file corruption or a inconsistency in file system causes broken encryption, so on unsuccessful boot the android format userdata partition automatically (if the ROM is designed to do this without your confirmation).
But as you stated there are still user files existing, there must be another storage or at least another partition.
Both is very unlikely, but I don't know that ROM. if you have the possibility to install terminal emulator, you can check what partitions exist with df

A factory reset should really wipe everything. If that is not the case the FYT units obviosuly do not do a real factory reset, but I personally never tested this.
The super partition, has the system, product, vendor and a few more partions. All are read-only and only writable on on a new flash.
Next to that is the data partition and the "external SD storage". They are writable.
So again: A factory reset should wipe the data partition and the SD-storage, not the system, product and vendor partition. So it is strange that data remains on the SD storage..
And that the data partition is wiped "regularly" is completely incomprehensible. If it is "simply" corrupt, so a file system corruption, a complete full flash should repair it. If there are really bad blocks on your internal memory then that wouldn't know if a full flash would fix that. In normal SSD usage this is monitored. I do not know for the EMMC memory in those units.
Anway: Did you ever do a "test only" flash?
Only the lsec6315update binary with only the updatecfg.txt containing only the word "test"? (test without the double quotes)

No I have not- what does test do?
I did try the twipe all on the last one and it seems to have not reset itself again since (fingers crossed that it stays that way! It's been a few weeks but that's about how long it lasted between resets last time).
Where can I read more about the test function of the flash?

Oh come on.
I have already pointed you a few times to my "General FYT based Spreadtrum uis7862 (unisoc ums512) - Q&A, Mods, tips, firmware".
It is described there. In this case in post #2.

It says there it tests the firmware. I knew that from the title already. I was wondering if you have more details than that but it's ok. I don't want to annoy you.

No it does not.
It says: test unit and firmware before flash
Also the unit will be tested
