Hello,
I have a PVT4 Desire with erasezize 40000
I am rootes and s-off
Recovery : Clockworkmod Alpharev Recovery 2.5.1.8
After i switch from Starburst Rom to a normal apps2sd+ rom, i got this:
E: Can´t mount /dev/block/mmcblk0p2 (File exists)
Error everytime in Recovery.
This error comes before i have to confirm the wipe of the dalvik cache.
I unrooted the phone with a official RUU and rooted it again and did s-off again,
but the error still exists.
Stock Rom is working, recovery is working, but i am afraid of flashing a new rom
Please help
Thank you
Do you still have the ext partition? I believe this is the error that you get when there is no ext partition.
no, i don´t have a ext partition, because it is a rooted stock rom running now without apps2sd+
its a new sdcard fat 32
do you mean if i create a new ext partition on the sd card, the error disappers ??
Yes but i don't know if there is any point in doing that.
ok, i created a new ext 3 partition on the sd card, but the error still exists
I found the exact error in a different thread here.
They managed to solve it
dunno if its of ne help....but i had the same prob of "E:Can't mount /dev/block/mmcbld0p2 (file exists)" with my HTC Desire with cynogen recovery mod and leedroid.
phone was getting stuck at boot screen. only recovery was working. i unmounted the SD card, deleted the ext3 partition through Disk Management in windows and mounted the card again. Now, android booted (but without A2SD) i downloaded ROM Manager and used the option "partition SD card" and like a miracle, the phone rebooted, partitioned my SD card, and rebooted back to android (this time WITH A2SD working!!!)
hope it gets as easy as this for u guys as well.
(P.S. : before A2SD, my internal space showed 92.4 mb, after A2SD started functioning, internal memory showed 130.2 mb)
PVT4 Desire's can't use CWM - they have to use AmonRA as highlighted in the stickied at the top of the General thread
stuck in bootloop, with same error in recovery
i have somehow managed to screw the device, it wont boot stuck at htc white screen, id really appreciate if you could help, i cant manage to get adb setup on my computer to list the connected devices maybe the driver issues
what i did to get into this was this:
1.i was using a custom rom from Auraxtsense 8.3 with Amon.RA recovery
2.i got into Rom Manager n install clockworkmod recovery just out of curiosity, the next reboot i was stuck on the htc screen
3.i can get into recovery n stuff, but i cannot mount my SD card, ive somehow managed to get my data out of the card by using it from another phone
steps tried:
1.i tried to go into fastboot n use a RUU to flash it but i got a Error 171 usb connection error
2.tried using Android fastboot commander but it fails to flash any type of file
i cannot understand the right process to go about things please help me, even if i can setup adb with the right drivers, access it from hboot or so push files make it stock then root n stuff again
formatted the sdcard totally to fat32 also n then tried via recovery to partition n all no luck

Flash the rom again but no wipe.
I get the /dev/block **** when I wipe Dalvik cache but everything is working fine.

hey thanks, i did that plus i also needed to run this command that seemed to have fixed the issue
Code:
fastboot oem enableqxdm 0
although i followed 2 threads
No-ADB-No-SD
&
Usb Brick Function
but jus used the command n formatted memory card n stuff worked not i couldnt move those 2 files mentioned here to the system since cat commands couldnt work
im still unsure device seems restored using my earlier rom from AuraxtSense with Data2SD
i still wonder if it completely fixed, n whether i should go ahead n create a goldcard, n like i need a guide to know what are the perfect things to do to keep as backup when such stuff happens

the error's gone, but problem exists
hey the error of the recovery not being able to access memory card is gone, but now when within the android OS the problem is when connected to the computer the charge sign or even the prompt to mount as disk drive does not show in the notification
in short i need to mount my memory card on the computer n the android OS cannot figure out how, is there somethin that may still be locked, i issued a command earlier from fastboot to get the earlier problem go
Code:
fastboot oem enableqxdm 0
You have the USB brick issue. The misc partition gets corrupted.
If you search you will find the solution.

hey thanks, i tried here
i need some help
Code:
3. Get flash_image from the attached files below
Move this to /data/ , and flash the modified image using:
"/data/flash_image misc /data/mtd0.img"
You can move both mtd0.img and flash_image by putting it on your sdcard, and issueing the following command in a terminal emulator:
'cat /sdcard/flash_image > /data/flash_image'
'cat /sdcard/mtd0.img > /data/mtd0.img'
You might have to do 'chmod u+x /data/flash_image' before you run the commands (or chmod 755 /data/flash_image)
4. Repeat step 3 a couple of times if it doesn't seem to work well.
5. All done! Reboot, you should have normal usb connectivity. Post your 'fastboot oem boot' log and intermediate steps if it fails.
i got the 2 files on my sdcard, im rooted but S-ON, i tried the 3 commands
cat /sdcard/flash_image > /data/flash_image
cat /sdcard/mtd0.img > /data/mtd0.img
chmod u+x /data/flash_image
in terminal emulator on phone, but when i press enter jus shows # again
then tried /data/flash_image misc /data/mtd0.img
says illegal instruction or somethin as an error
can you help me if im doin this rite? i browsed the /data/ folder via a ESFile Browser it seemed to be empty
I had this issue with my SD using, i solved it. Just partition your SD with 512mb for ext2 primary and the rest for fat32 WITH ALSO primary partition, I was using FAT32 Primary and EXT Logical, thats why i got the error =)
Hope it helps, and sorry for my bad english
hi guys, im also getting the following error... E:cant mount /dev/block/mmcblk0p2
i have searched for days now trying to find the solution, i see something about adb and command lines etc but i have no idea how to do that!
plus i see that it means that ineternal partitions are somehow messed up, but i only get this error with one of my sd cards.. my old one works fine. so surely it is a sd card problem,
i have so far tried partitoning with cwm recovery, in windows, using gparted and no luck.. as anyone found a definate solution yet?!
thanks

hey i had this problem a few weeks back
refer this thread just to get the update.zip file
1.format your SD card to FAT32, put update.zip on it
2.boot into fastboot, connect usb cord to phone n computer
to get into fastboot mode
press volume down + power held for a few seconds when phone is off
then press volume down once n enter fastboot
then connect the phone to the computer
3.on the computer run command prompt n browse to the director with android SDK n go into the tools folder
execute this command
Code:
fastboot oem enableqxdm 0
4.once this is done, the SD card is then recognized by the recovery
5.now reboot go back into recovery from the same volume down+power sequence n then say flash zip from SD card
to get into recovery
vol down + power at start n then select recovery (having access to recovery is important)
then choose flash zip from sd n flash the file update.zip from your sd card
basically the fastboot command n format of the sd card should be fine to let you flash a new ROM zip file n get the phone started
but the issue is actually called a USB brick in which, you lose access to bluetooth, battery drains a lot, n there is no way to access mem card via usb on the computer its not recognized
hence i flashed this update file from that forum there, which describes the fix in detail
I recently flashed Paranoidandroid rom and thought I would try another rom, so I went and deleted data and went to navigate and install from my sdcard. It had an issue so I re-flashed el29 kernel via odin and when I came back into the recovery I couldn't mount my sdcard and was having problems when viewing it via windows. When I try to mount /sdcard I just get "Error mounting /sdcard", and when I try to mount usb storage I get an issue with writing to the lunfile.
As it stands I cannot do anything on my phone if it involves flashing from the sdcard. Is there a way to fix it via odin. the phone isn't recognized by adb so any solution requiring that will not work.
El29? Go back to el26 and see what happens

I was able to flash stock using QBKing's tutorial, then re-rooted and reflashed cwm, but the sdcard still has issues mounting. WHen I'm in stock it displays a notification saying "Blank sdcard, please format" but it never does.

It's quite possible the card is toast.
Have you tried mounting it on a PC?
If it mounts on the PC you run a chkdsk with repair on it. Open command prompt then:
chkdsk x: /r (x being your SDcard drive letter.)
What about formating it (FAT32) on the PC id it shows up too.
Good luck.
Ok, here is the problem, i woke up today, my phone battery was empty, i connected the phone battery was loading, but i couldn't get to the system, after kernel load it stops, like there was no system installed. Everything worked fine day before,my configuration was: Doomkernel and Existenz_2.0.5 ROM.
So, i got to recovery (recovery works,CWM), and there i saw "can't mount cache" error. I got into shell with adb (this works too), and there is no way i can mount any system partition (/system, /cache, /data), what's more important /sdcard does not mount either. So, i'm in recovery, can't install or restore from sdcard,cause /sdcard does not mount.
I'v tried sideload, no go.
I've tried fastboot flash new kernel, and here's interesing thing, fastboot reported that flashing was ok, but i still have Doomkernel (i was trying to flash 6.0-TUX-Core-HD kernel. So seems like fastboot did not write anything at all.
I've tried flashtool with stock tft. It breaks with "final verification error", when i turn "final verification off" it goes all the way, says everything is installed, but when i restarted, still only Doomkernel.
Any ideas ? I take any advice.
Maybe you have already tried it, but format your phone's data, THEN the cache, and finally the internal storage (SD card). In XS's CWM, there's a bug, which causes sometimes an unformatable and unusable cache parition. But this method can be help on this. Maybe this problem causes those unformatable partitions.

Thank you for your reply. Haven't tried that but i have now and, unfortunately, no go. With /data and /cache seems like format was success but it didn't ( still can't Mount) and with /sdcard format fails (error mounting /sdcard).
Maybe my sdcard really died ?

Well, I don't think so. The "SD Card" is a part of the memory chip, which includes the system, the data and the cache partitions too. Because you cannot copy anything now to the internal storage, try to install a ROM from ADB Sideload if you can. Once it done, your phone can be boot maybe again. If it happens, try to format the internal storage by the Android. If it fails, connect the phone to your computer, and try to format with Windows or (it can be better) Linux to fat32 filesystem.

Thank you for your ideas. Thing is, all i can start is cwm recovery. As i wrote, i can't install anything with sideload. And no partition is working. When i start parted /dev/block/mmcblk and try to list partitions, i get unrecognized disk label error, when i try to manually set disk label to msdos, there's I/O Error.
And i can't format sdcard, because when in recovery, phone is not detected by Linux nor Windows. But i tried formatting partitions internally, with mke2fs, and with fastboot command. No go.
I know that /sdcard is just a partition, but what i meant was that probably my phone memory chip died, like hardware died. but i'm still looking for new ideas i want to try everything before giving up.

Then maybe it's a HW error really. But maybe just the partition table is corrupted. At this point, I don't know. I have only one suggestion left: Take the phone to the nearest SONY Center or GSM shop/service to investigation. But I think they will say you'll need to replace the phone's motherboard. Anyway, it's an too expensive solution I think, because this phone is a "retired" modell without any update, but with a "blacksheep (Snapdragon S3) SoC.
unable to mount /data
No idea what happened.
Woke up today.. phone seemed off .. tried to charge and reboot and could not.
Got into recovery, and tried to wipe caches etc.. could not..
This is the message I get in logs from TWRP.
I read in another forum about going into the console and typing a manual command to reformat the partition.
I have no idea if that command would be the same here..
ANYONE??? please?
You didn't post the command, but just from common knowledge I'd say the Linux command would be the same, but the partition you need to format might be/probably is named differently on this phone.
Incidentally, there is always the possibility of partial or full emmc failure. Your description of the symptoms sound consistent with hardware failure, so I wouldn't rule out that possibility.
I just had the same thing happen. Can't find the command to manually reformat as well. My external SD card was wiped as well, apparently. Or it won't read it. TWRP also says internal storage is 0 mb.
