[Q] help E: Can't mount /dev/block/mmcblk0p2 - Droid Incredible Q&A, Help & Troubleshooting

ok so i've searched around and cant find a definite answer on what /dev/block/mmcblk0p2 is, i believe its sdcard ext? but i do not have a partitioned sd...problem is my phone will not boot, i have been trying to use swap on my droid inc and ****ed it up by trying to use this location for it, it obviously tried creating a file and messed it up somehow...how can i fix this issue so my phone will boot?
edit: cant use recovery either, same error, also my sd card will not mount on computer but im able to back it up using the mount in clockwork recovery, im using cm6.1 too if anyone needs that

cant even wipe/factory reset...
edit: can now mount sd-ext, but not cache...phone still not booting
found this http://forum.cyanogenmod.com/topic/...mmcblk0++mkfs++ext2__fromsearch__1#entry56396
seems to have worked

[Q] How screwed am I?

I only loaded a new rom on the incredible successfully once, last summer when the signed 2.2 rom came out early and I couldn't wait for the OTA.
I had this problem crop up that said my storage was full when I had gobs of space left on my internal storage and my sd card. Finally, after I did the factory reset option and still had the storage issue, I decided to try reflashing with a new rom because my phone was becoming unusable. I couldn't install apps, save contacts or even open text messages. My phone wouldn't even sync with Google.
I decided to try flashing with the redemption rom after reading some good things about it.
I managed to load it successfully, but I still had the storage error! argh!
After trying to reformat some things with the ClockworkMod Recovery partition menu, I tried to reload the redemption rom again. Something went wrong.
Now I get messages saying(on the ClockworkMod recovery screen):
_______
E:Can't mount /dev/block/mmcblk0p2
(file exists)
E:Can't mount Cache:recovery/command
E:Can't mount /dev/block/mmcblk0p2
(file exists)
E:Can't mount Cache:recovery/log
E:Can't mount /dev/block/mmcblk0p2
(file exists)
When I choose the option to install the redemption rom off my sd card in the clockworkmod, it fails after giving me similar error messages.
I'm stumped. Can anyone point me towards the right thread to deal with this? I can't boot to install any other software onto my phone. Practically everything I try gives me can't mount error messages.
I was hungry and in a hurry and never made a nandroid backup I HAVE tried reformatting the sd card, but I got no different results from that.
So am I A) totally screwed, B) somewhat screwed, or C) not screwed at all, just an idiot?
Help?
im in the same boat. i have no idea how to fix it. ive tried every fic i can find on google and NOTHING works. someone HALP
forum.cyanogenmod.com/topic/6433-solved-messed-up-partitions-on-internal-storage/page__st__20 the site wont let me post a link, but this is what i used. i can now mount data and cache. working on booting now.
Have you tried a different SD card? Your SD card could have failed or become corrupt in some way.
I doubt you are totally messed up. You may need to get a brand new factory ROM (on your new SD Card) and start from there. Just Google it. As for an SD Card, there will be a few on sale Friday.
As for the full memory, I had that same problem, it's a cache issue with the HTC software (HTC Mail, Facebook, Peep and such). Once you get back up and running make sure you root (unrEVOked is working on a work around for the latest mid Nov OTA but there are other ways to root) and get a Cache Cleaner. It's not a permanent fix, but it does work.
Good luck!
Thanks for the response. I have yet to try Barbee's solution, but I did try another SD Card. I reformatted both cards to Fat32 and had the same error message on both. I'm going to go grab my phone and try Barbee's solution next.
it might be that version of CWM recovery is just retarded. what version are you on
I take no credit for this but try this its on Adrynalyne's blog http://adrynalyne.us/
"There have been a few cases where /cache has been corrupting on the DI."
"To fix this, you must be in clockwork recovery.
First, unmount cache from partitions menu.
Then, mount system from the same menu.
adb shell
system/bin/e2fsck -p /dev/block/mmcblk0p2
exit"
That should fix the issue you guys are having.
Thanks Barbee, I was able to unbrick with your solution! Pretty muh all of that was way over my head, but the instructions were clear and they worked. Now I just need to get that Redemption rom to work with the *228 option1 programming on the phone... that doesn't work now lol.
That's easy, go into settings sounds and turn the touch tones to long. This is common in custom roms.

what happened was you trashed your internal partitions using cwm partitioner......the method on cyanogen's forum shows how to properly reformat the internal partitions to ext2 and gets you back to having a usable phone.
Glad to hear it helped you. But all the credit goes to the guys in the link post. It was a little over my head too lol. I've used adb before but not for a life or death situation lol

Boot loops and CWM issues

Hello all,
i have been around on the site for a while reading, learning, and rooting my DInc. I have SkyRaider 3.5 w/ stock kernal. Currently running CWM 2.5.0.5. I was going to dip into the realm of setting CPU settings for different functions. I DLed SetCPU from the market and installed. i figured this would be a good time to do a backup through CWM in case i eff something up. after the backup completed, i selected the "reboot system now"
Upon rebooting, it loaded into my lock screen with the stock background and clock, not the ones i had before the backup process. when i did the slide unlock, it would just go to an all white screen with the htc green logo in the middle, and all my buttons but the power button were useless. strange i thought.....so i pulled the battery and proceeded into the CWM again to restore to a previous backup. got into CWM just fine, but now i had 5 message lines at the bottom of the CWM screen:
E:Cant mount /dev/block/mmcblk0p2
(file exists)
E:Cant mount CACHE:recovery/command
E:Cant mount /dev/block/mmcblk0p2
(File exists)
E:Cant mount CACHE:recovery/log
E:Cant mount /dev/block/mmcblk0p2
(File exists)
Then, i go into the backup and restore option, and select restore, it kicks me back to the main menu with 5 more messages:
E:Cant mount /dev/block/mmcblk1p1 (or /dev/bloc
k/mmcblk1)
(No such file or directory)
E:Cant mount /sdcard
E:Cant mount /dev/block/mmcblk0p2
(File exists)
E:Cant mount CACHE:recovery/log
E:Cant mount /dev/block/mmcblk0p2
(File exists)
I've tried doing a wipe data/factory reset, and it gives me a bunch of mounting errors and basically skips all format, then kicks me back to main menu in less than 3 seconds.
I've done a fair amount of research for this and can't find anything related to the DInc for this issue. Seen it on a few other devices (earlier droids) but not sure how much that info pertains to this device.
unfortunately i do not have a micro-sd card reader on my computer, so i have not tried re-flashing my ROM since i do not have a ROM on my SD card, not sure if it would be of any use since it sounds like my SD card is not mounting properly.
I will probably go out and buy a universal card reader (should come in handy) as well as a second SD card in case it happens to be the SD card that crapped out.
I figured I'd get this up here anyways to see if anyone can help.
Thanks so much for any advise or fixes you may be able to offer!

update
well, i managed to do a couple hboot updates and basically return my phone to the way it was when i got it from the store. i have no idea what caused it, but the original sd card still works, albeit reformatted, and the phone is functioning perfectly so far. I'm still curious to see if anyone had any ideas about what happened. sorry i can be of service to troubleshoot since i fixed it (the long way). my phone is too vital and i have travel coming up.
Thanks,
Trey
When I tethered my incredible to my pc I would get errors. I've had to actually run defrag on my sd card. I actually have several Micro sd readers but I was lazy and did this after tethering to my pc. Seems to have fixed the problem
So, I decided to try to go back to root last night, with the help of Preludedrew. rooted using unrevoked3 and updated to CWM 3. when it was all finished, it left me in CWM recovery and i had new E: errors:
E:Can't mount /dev/recovery/log
E:Can't open /dev/recovery/log
E:Can't mount /dev/recovery/last log ?
E:Can't open /dev/recovery/last log
when i would try to mount cache or sdcard, it would still fail, and when trying to load zip from sdcard, it would error in trying to mount sdcard.
with some more help from drew, we tried using adb shell to mount/access some partitions, and the mmcblk0p2 (i think) could not be found on the device.
thankfully the phone still booted this time, but i went into the phone settings under SD & storage...and the sdcard was there showing my 15GB of total/available space.
But....under the internal phone storage section, it said "unavailable" for both total space and available space.
so the only thing we could somewhat deduce, is that the internal phone memory has crapped out, thus when i RUU'd (?) back to stock, it could not find my phone internal storage so it just reassigned my sdcard to the 0p1 block, and where the sdcard should be in the 0p2 block there is nothing. Hence why cwm cant find anything related to my sdcard since its looking in the 0p2 block.
so now that i'm back to stock, i'll take it to the verizon store today and see what they'll do about it since the internal memory seems to be crap. i have insurance, so i dont think it will be a problem getting a new phone, unless they want to try to replace the internal memory, which is fine with me.
unless anyone has any other ideas?
sorry for the noobish verbage, i'm trying to remember what i all did at 1230 last night.
Thanks,
sorry for the quick reply, but i just had the idea to try mounting my device as disk storage, since it should come up as 2 drives (internal phone and sdcard) on my computer
both drives show up under my computer, sdcard access is fine, but when i try to access the other drive, i get "please insert a disk into drive G:"
and when i switch back to charge only, it will only say "preparing sd storage" and doesnt do "preparing phone storage" like i thought i remember it doing when it was still good.
I guess just another reaffirmation that the storage space is crap.

[Q]{FIXED!} E:Can't mount /dev/block/mmcblk0p2 {FIXED!}

Hi all. Got a bit of a problem. I have been using InsertCoinGB S2.1 ROMs for a while now and went to flash v22 this morning. Decided I would also take the step of updating my CWM to 3.0.2.8, as well as ext3 alignment, at the same time.
So, steps taken were Nandroid backup, apply update.zip, flash alignment_ext3.zip, flash ROM. All seemed to go well, but got stuck at splash screen. Pulled battery and got back into Recovery, then tried to restore Nandroid...
Ended up with
E:Can't mount /dev/block/mmcblk0p2
(File exists)
Error mounting /sd-ext/!
Skipping format...
E:Can't mount /dev/block/mmcblk0p2
(File exists)
Error mounting /sd-ext/!
Help!! I am pretty sure I have stuffed my SD, but hopefully not the whole phone. I have an 8gig at home that I was using prior to current 16g...I might be able to swap that in, just means I will lose all data from past week, which is not so bad...
I have done a fair bit of googling and searching here, but most remedies seem to rely on being able to boot into ROM and repair thru ROM Manager or GParted etc, but I am unable to get past Recovery or splash screen. I am S-On, btw and had 996mB Ext3/13.xFAT32...
Any ideas??
Cheers.
EDIT: Fixed. Phew! Was able to run home at lunch and thanks to clunky old Dell laptop, I found that my SD was not dead, just wounded. Had a GParted disk ready to go, so was able to format Ext3, boot up and flash Recovery. Will try to flash v22 again later...

[Q] Can't mount SD card in recovery to flash a new rom, help!

Hi there,
I was about to flash a new rom on my Dinc, and right after I formatted /system, the sdcard became unable to mount and now I can't access the .zip for the new rom. I've tried flashing 3 versions of CWM as well as one of TWRP but none of them can access my SD card. I also reformatted it in my PC with no success. I currently don't have any operating system on it so all I can work with is hboot and recovery.
Can anyone help me fix this?

Did you format it fat32 with the pc? If the cards fine (can be used by pc and fat32) and recovery and hboot still cant find it, then id venture to say the sdcard slot is damaged or went out.
Using adb in recovery, you should be able to push a rom file to emmc and flash it from there.

I did format it FAT32, and the SD card is definitely fine. I don't think that the slot is the problem either because other things won't mount either.
Actually the only thing I can mount in recovery is /system, everything else is inaccessible. It was having mounting problems before which is why I decided to flash it with a new rom (was running Jellybean very poorly). I also tried flashing the original recovery, doing "clear storage" that way, and reflashing with CWM but it had no effect. During the storage wipe it said that /datadata doesn't even exist. It also shows errors that it can't mount the files /dev/block/mmcblk01 and /dev/blk/mmcblk0p2
This is what the log shows when I did the CLEAR STORAGE using the stock recovery
Restore factory NV setting...
Formatting DATA:...
E: format_root_device: can't find mtd partition "datadata"
Formatting EMMC:...
Formatting CACHE:...
Wipe ALL failed.
E:Can't mount DATADATA:recovery/log
E:Can't mount /dev/block/mmcblk0p2 (or /dev/block/mmcblk1)
(No such file or directory)
The same thing happened to me long back. What I did was that I cleared data, cache, and dalvik cache... Worked for me... You can try but i wont take any responsibility

Unable to mount

Hi
I have a HTC One M8 and it was rooted and flashed with cyanogenmod. Today my phone just died by itself so I tried to start it up again. what happend was weird, it got stuck on the boot animation. i tried to shut it of and on and it kept getting stuck on the boot animation. I got in to the TWRP (2.7) recovery mode and tried everything there. I try to factory reset it and I get failed. it just says Unable to mount '/data' and Unable to mount internal storage. I try to shut it of and now it says that I don't have any OS installed. Through guides I mange to transfer a new cyanogenmod rom to the phone in hopes of trying to reflash it. But again, when I try to flash it I get failed and it says Unable to mount '/data' and Unable to mount internal storage.
I don't know what to do, I'm stuck. Help appriciated. I don't know what more information is needed to able to help me.
so through a lot of searching, I think that my main problem is because i can not mount my data folder. Everything I do, I get the message E: Unable to mount '/data'. I look inside data and the folder is empty. I tried this "How to: Fix a corrupted DATA partition on the HTC One" on Android Revolution HD (can't link the site since i'm a new member) and it didnt help. I got stuck at the "mount /data" command. The whole folder seems corrupt. I read on some places that I should format it in windows manager but that doesn't seem possible. My phone appears as a "CD-device(F" on my computer and I cant format that.
This is my only working phone and I really need it to work. plz help.
I've tried dozens of unrooting guides but none of them seem to work because of my mount problem.

What carrier are you on?
Try to flash TWRP again. And update the version. Sometimes this alone will fix the data partition not mounting bug.

Hey, i just got the EXACT EXACT same problem! Did you manage to workout a solution for it? I've been reading all
day threads of the "E: Unable to mount '/data" problem, and i'm really really confused about what to do.. would be great if you could tell me how it went. :good:
