No access to the internal NAND Flash

---

Hi all!

Well, I will be really very glad if somebody can help me...

The problem is that I can't reach NAND FLASH in my 6500 any more. It disappered in the file explorer. I made hard reset, then i used the standard HTC utility to get the NAND back, but no success!

Probably, i have to try to change the ROM?

The device is from Germany, ROM 1.10.407.3, Radio 1.58.21.23

And one more question: how to dump(make BACKUP) the original ROM before flashing new?

Did you ever fix this? I ran into the same problem and learned that the solution is to use the Format NAND Flash utility, but to use the "Recover NAND Flash" option. It reboots the phone, which then has to just sit around a while while the system figures out how to get the NAND Flash fixed. But this worked for me!

Hi there, I have had the same problem. I followed Recover Mass Storage procedure, which reset the device. I waited for a few hours but the Mass Storage never came back. Any suggestions? please?

I'm afraid not -- whenever this has happened to me (and it's happened twice in a year of owning the phone), it's been fixed by some combination of soft-resets, "Recover Mass Storage," and a bit of time. If none of that works, I'd say it's time to call tech support. I've actually found them easy to reach and quite responsive, at least here in the States.

Sorry -- I feel for you and wish I had more advice to offer!

sucess...

dont know how carrot got that to work... what rom did you have...?

anyhow i had the same problem... NAND Flash dissapered... and i followed his directions and it did not come back....
so i snooped around and finally got it back...

1 try to recover with HTC app.. (no Sucess)
2 get gsFinder or something similar and goto \windows\startup\ and you will see ManualFormatmoviNAND.lnk
well this need editing...go into properties ... you just need to put .exe at end of ManualFormatmoviNAND ...before /RUN
3 then power off device for bout 5 mins...or take battery out for so long
4 then power on and it boots up and then you will get question to format...
sucess !!!

After more Snooping i discovered before you do anything like this that will format the NANd flash you should just take out battery for about 5 mins and that should work to bring back nand flash with everything still intact, at least it does for me. I formated the nand flash with a backup copy of the FAT table with SoftWinter, Storage Tools, so that might help. the built in NAND flash Format Tool does not creat a backup FAT table when formating...
SO now if it disappears i just Power off (press power button for 5 seconds till Message...) or take out battery and then in a few minutes its back with all stuff intact...easy!!!
