Hi all,
My girlfriend has an XDA-II that - on a whim - decided to hard reset itself. (It has done this once before for me aswell.)
Most of the lost files are of no consequence because a backup is available. However, there is one Word document that we would like to recover that is not backed up. The device has not been used since the hard reset.
I presume that it is likely that the text contents of this Word file are likely to still be in tact somewhere in the RAM (i.e. the bytes are unlikely to have been overwritten just yet). I suppose then that it must be possible - at least theoretically - to obtain a dump of all the contents of the volatile RAM memory (perhaps writing out the contents of RAM to a PC hard drive in one dump).
With this resulting RAM dump I could then search it for words that we know are definitely in the file to obtain most of the text back again.
I was wondering if anyone knows of any program for the XDA-II (or PC) that will copy the ENTIRE contents of all device RAM - byte-for-byte - to the PC.
Failing this, can anyone suggest any way whatsoever to view/copy RAM contents byte-for-byte?
Many Thanks,
Rob
you can undelete media like hd's magnetic storage and flash
because they dont fill in 0's in the bits when they delete they just free up the storage and overwrite the data next time data is saved
ram however goes 100% blank when power is not supplied
so ram cant be undeleted and data cant be recovered from it
which is why newer devices with 2005 place data in flash and not in ram
so their device dont goes blank when a hardreset or dead batt happens
Thanks
Not the feedback I was hoping to get! But thankyou very much all the same for letting me know.
Cheers.
Rob
Help please. All my data get lost!
I know the data on the card, but just cannot see them.
From checking the property of datacard, i know that all the data still on it. however, after open the card, just 2 files which i never know, all the others gone.
Don't know what my trinity did on my datacard wile i using the bluetooth internet sharing with my pc. After that, this happened.
All 1.4GB data disappeared!
Please, anyone can help?

sure, it's my pleasure to help others here.
I use wm6 with a 4GB MINI SDHC(Karmba 4.0). After i use bluetooth internet sharing with my laptop, i found that all 1.4GB data disapeared from my sd card. Instead of them, i saw 3 files which have strage name on them and cannot be opened. All these files are 0byte. Then i insert sd into my laptop, right click sd to check property, i knew all data still on sd card, because the property of sd card shows "1.4GB used". After that, i enable my laptop to see hiden files, not see anything from sd card again.
Finnally, i found a tool called "Final recovery". This tool bring the most of files back to me, not all of them.
I suppose, the internet sharing write all the internet temp files into my sd card, then all my data had been overwrited. So, even when i use recovery tool, cannot recover all of them.
Karmba 4.0 set internet cache and temp folder in the sd card by default(Karmba 4.1 maybe does the same thing). Thus, i think maybe this is where the problem comes from.
By the way, i really appreciate what Karmba did for all the user here. His rom is quite good, But i think 1.2 is the best one. The others really need debug.
Hope this information can help other people who have the same problem. Cheers.
It's nice for you to share about your experience regarding recovery.
However, I think it's worthy to point out that SD corruption could be caused by almost any program that access the card. It has been discussed many times in the forum.
It's actually a HTC bug, which goes unfixed. Artemis got a fix to its SD driver long time ago.... Anyway, prevention in my opinion is far better than recovery. Look for a program called "sdsentry" and it will notify you when the corruption occurs and allows you to reboot the machine to prevent the corrupted FAT image got written to the card itself. It will save your day. Try it.
What the hell? Before I've changed the File system cache to auto it did work! But now that I have much more ram available about 21MB, it doesn't want to start. So I tried to go back to 4MB file system cache... but nothing, still that error message.
TomTom 7 is installed in the memory card... wtf???

I've had this happen before, and if I remember correctly, it was a corrupt Map File. I restored an earlier copy of my maps to the SD Card, and all was good again.
Try hiding your maps and see if TomTom will run. It should ask you to use a Voucher. If it does, then it's the map problem and TomTom is fine.
Nope, I've tried this tip but no success... It's really odd...
Hi Zooster. Sorry to hear about the headache you currently have.
I have had similar problems in the past month, the first time really freaked me out.
In my case, I noticed that some of the files on my sd card know longer showed up, and later discovered that others had indeed become corrupted.
I solved it (and continue to do so when it happens) by formatting my sd card and copying back onto it a copy I have of all the Tomtom files. Infact, once you get it working again, I suggest you regularly make a copy of whatever is on your sd card in case it happens again. For me, it seems to be ROM specific, i.e. only happens when I flash some of the new ROMs. Sometimes the sd card suddenly stops showing up in file explorer, sometimes I just need to remove tomtom and then reinstall it.
The problem for you now may be getting the original Tomtom files, I guess it depends where you got them from.
When I flash some ROMS, this problem occurs. I have to avoid ROMs that do that and choose another.
I hope you manage to sort it out. I know what's it like when these things suddenly go wrong for no reason! Best of luck.
Mattster.
Ok, I'll try to restore original files... I'll let you know.
WHAT TOMTOM FILES DO YOU NEED ON YOUR SD CARD?
There seems to be an awful lot of tomtom files on my sd card, so I've started to delete some and see if Tomtom still works. And it does!
I've got it down to:
My Documents folder with maps inside
Voices folder
plus the following files:
ALBUM.VOL
AutoRun
Autorun.exe-run
Start
TTN
TTN2003
ttnavigator.bif
I've lost the 2257 file (that apparently causes automatic self install of Tomtom when you insert the card) so if anyone has that I'd like it back!!!
So, my question to all of you Tomtom users is: Which files are actually needed for Tomtom to work?
(I know there is the tidy up option of chucking any mystery files into a folder, but I like to know what all files on my sd card are actually doing!)
Mattster.
Hmmm...
Just had this problem myself, but might have fixed it on my Artemis
Originally I copied the TomTom Navigator.EXE to \windows\start menu\programs and it worked
However; it stopped working with the "not enough memory error" - so I started disabling applications, uninstalling them etc.
Still no joy
Just out of interest tried the TomTom Navigator.EXE within the TomTom folder on my SD card - and it worked...
I've deleted the .exe from "my device" and created a shortcut to my SD Card and now it looks like it is working again
Going to keep testing now - but perhaps worth a shot

For tomtom, TTN is the installation file, the others can be all deleted.
After installation, we only need the following 3 folders:
1. maps
2. voices
3. zip
All of them need stored in sd card root path.
If you need the satellite view, then you need one more folder in your sd card root, which is "raster"
The file "ttnavigator.bif" is auto generated by tomtom everytime you use it, you will always find it is still there even you have delete it sometime before, just leave it. Also "ttnavigator.bif" is a log file for tomtom, so it is useful, dont delete this file.

In the 2577 (not 2257) map are the following files:
AutoRun.exe
Autorun.exe-run
TTN.cab
TTN2003.cab
So you just moved them to the root
The actual files for running TT are automatically stored on the device, not on the storage card

Thanks Arjan. Thanks for the reply.
What I'm curious to know is, after a new ROM flash (i.e. before TT has been installed on their clean device) what TT files do they have on the SD card.

Sorry, can't answer that. Flashed my rom quite a few times but never bothered to clean up my storage card. Probably still got Tom Tom 6 and or WM5 stuff on there
i had the issue with artemis and tomtom Navigator v7.910.9185. It was on sd. Then i deleted voice and raster folder and suddenly the problem solved!
Then i copied voice folder back to sd with 3 voices (before i had about 25) and now it works like charm.
I have had this same 'memory' problem on a few devices,
it has always been sorted by an SD card format and a card restore from my PC.
as to Tomtom after a re-flash ... I have never had any issues with it at all,
I just restore a full backup with SPB backup.
i have tomtom 7 ver. 7.910 on my p3600 running wm6 pro but seems to always come up no gps device can anyone help, please send me a message soon thanks mossy
Go to Change Preferences, Configure GPS, Click Configure, Tap left Arrow to show Other NMEA GPS receiver and tap Select, Set 4800 Baud and tap Done, Select GPS in COM9, and you are good to go. Click Done to go back to main screen.
I had the same problem once, install chaps advance config an relocate the internet temporary internet files.
by default they are located in: \windows\profiles\guest
if you use youtube a lot and google maps i can happen too.
I get this all of the time.
the problem occurs when my battery gets lower than 70% and I launch TomTom Navigator 7.
what i do now is make a copy of the Map Folder and keep it on my memory card.
I also make a zip archive and keep that on my device (not SD Card) in My Docs or somewhere else with a copy of the corresponding .dct file and .bif files and installers.
this way, i can restore tomtom onto another sd card if need be.
usually i format the card and restore the zip archive!

Just had this same problem. Changing the Start Menu from a copy of the executable to a shortcut seems to have fixed it. Thanks for the tip!

Formatted sd card, reinstalled maps and everything needed from a backup = works.

Hey All,
This is my first post but joined long ago, Great forum by the way
Please tell me if this post is in wrong section...
I have a Jasjam running:
WM6 Professional
ROM Version 3.62.305.5
ROM Date 11/06/07
Radio Version 1.54.30.10
Protocol Version 32.87.1020.20H
ExtROM Version 3.62.305.116
I'm having the following problems over the last few days, Was fine previously...
1. Phone is running slow,
2. Can't always send sms messages and "locks up" in message function, I have to stop this via settings to egt out of sms area......
3.Storage Memory is full - even after deleting text messages and uninstalling some software. Space frees up once this is done and then seems to somehow get full again without explaination...
I have even moved everything I can from phone to storage card and memory increased, then I get same error message again and somehow memory is full again...
Keep getting this meesage "Storage memory is critically low. If storage memory is not increased, other programs may not be able to start. Use file explorer to delete files that are no longer needed or move some files to a storage card"
Please help, Is my phone stuffed?
Thanks in advance.....

try to flash a new rom?
I really didn't want to do anything except correct fault, as it just suddenly started having this error. I will only reflashing if I can't resolve it any other way. Thanks
try searching for sktools, I am not going to post it here unless it is necessary it is floating everywhere here.
try this
try oxios memory
If you are installing it in the phone memory then try to unload few programs that you use less. Install them on storage memory card, do you know that SD card thing. Increase your SD card memory to 2 GB if it support or try 1 GB as I am using it and don't need more of it. Also try to transfer your pictures and movies to the storage card.
Hope this will solve your problem.
Use ActiveSync Explorer to do the job or use any file explorer other than the windows own. GS Finder is the one I like but there are other available on net.
Not posting here coz it will make people lazy. Try to use search and get use to it.
Low mem
hi, as a ex hermes user I too faced this problem many times.
My issue was too many emails and attachments.
I had outlook on my pc synced for all messages from last 30 days (usb), plus 2 other email accounts with about 5000 messages done via 3g when out and about it killed my mem free untill I eased back on the qty I needed.
Hope helps
Fadge
I know the answer to this!!! You have to delete temporary internet files although you might have figured it out by now
I actually just re-installed WM6 and the problem is now resolved.
Jason
In other words, you just wiped everything out of the phones memory.... As was suggested by just about every other post after beastfellows post...
Make sure you save attachements for sms/mms/email, save as many apps to the memory card and put all pictures and music on the memory card or you will be back to the same point pretty quick...
Cheers...
Ok so this sounds strange but I was recently very close to tapped out of space on my 8gig shipped micro sd card.. I recently deleted a movie that I encoded to .mp4 on it.. I used Astro to delete the file which was over 1gigabyte in size.. here is the problem.. file looks like it's gone yet the space was never re allocated to "free space" Any ideas?? Maybe it was flaged hidden? Can someone please help?
Have you tried hooking it up to yuor PC and seeing if the file shows up (you can set to view hidden though i dont think you can hide in astro) this should help you see if the file is acctually gone.
Something else i always forget to do is clear out some old nands as they take up 200ish+ mb each i flasha lot and always forget till i see i am low on space to clean up the folder and get rid of a few old ones.

Yes that's exactly what I tried. I also searched for it. Does Android possibly auto move it to Rom if your copy to SD doesn't have capacity? This is really strange..
