Hey guys
This is my 3rd time rooting my phone and I keep getting the error
unable to mount to /dev/block/mmcblk1p1 when trying to run the update.
I can not even see my SD card inside android.
I have already reformatted my card to see if that would fix the problem.
Is there some mount command I can run from root to fix this issue?
Thanks!

This should go in Q&A, really, but here goes.
There are four possible causes:
1. SDcard failure (try another to eliminate this prob)
2. SDcard corruption (try another OS to format it, like an old smartphone or linux)
3. DI Software corruption (least likely, but can be eliminated by a bootloader PB31IMG.zip flash -- know that this fix would blank all your userdata, apps, settings, not stored outside of the 1gb nand&RAM).
4 DI Hardware failure (this possiblity is why I hated the rapid sdcard eject/insert method--that sdcard lock mechanism is just a itty bit of spring steel and an itty bitty little latch) -- how to eliminate? try the card in a card reader or device.
Good luck!
what was the file system type that you partition the card to?
Its fat32, and thats what I reformatted it to also.
For the HTC HD2 only (someone said in this thread)
Format won't help since it won't unlock your sd card and won't delete the internal protection. You need to do the following.
1. start linux (install ubuntu besides windows or something)
2. put card in computer
3. unmount sd card with "umount"
4. format sd card with "mke2fs /location-of-sd-card/"
5. go to windows and format as fat32 or just put it in your phone.
6. thank me
Windows or your phone will say it's broken or something and will repair.
The mango security is no more and your sd card is revived.
If I did something wrong, let me know, it's my first post.

If I'm not mistaken, there's two different types of security being used; there's the kind being used on the HD2, and then there's the kind being used on native WP7 phones. Does this method work with the latter? As far as I know, no other method except the Symbian trick will work with a card that's fully locked.
Also, for the record, installing Ubuntu (or any other Linux) is a waste of time if you're just doing something small like this; there are many Linux distributions (including Ubuntu, incidentally) available as a "Live CD" or "Live DVD" that the computer boots off of directly. No installation required.
The location of the SD card will be under /dev/. If your Linu install actually tries to mount the SD card, you can type "mount" in the console to see all current mounted devices, which should make it easy to figure out which is the SD card.

Works with the latter. And I think it works with all security methods I guess since it overrides all bytes with a linux ext3 partition. Please correct me if I am wrong.
Installing Ubuntu from http://www.ubuntu.com/download/ubuntu/windows-installer besides Windows is faster than burning a live cd or something like that.
Also sd card mount location can also be /media/.
Please try my suggestion and fill me in where I have forgotten something, since I don't fully remember the steps I took.

Your suggestions are useless for all handsets except HD2 because of security scheme used by MS. Try to search forum first before posting - it's a very well known issue with 100% proved resolution (Nokia's handsets).
Thank you for reply.
I did search, for hours. And you're right, I did it for the HD2.
So I will alter title for HD2 only.

you don't need linux for this, in windows you can use diskpart
- type diskpart in the runwindow (winkey + r)
- in diskpart type "list disk" without quotes
- type "select disk x", x represents the disknumber in the left collum, be carefull to select the right one, you don't want to erase your external hd or anything like that.
- type "clean", ALL partitions will now be removed from the card, as well as an mbr or bootsector wich might be there if you ever made it bootable. Your card is now not more than an expensive brick
- type "create partition primary", a new primary partition will be created as big as possible (16GB in your case)
- type active if you want to set the partition active

that doesn't work for me, it's not finding the disk (no media) .. going to try ubuntu now
@romusters: The mount point will be in /media. The *device* will be in /dev/ and must not be confused with the mount point. It's the equivalent of confusing C:\ (mount point, Linux equivalent is / (root), people generally know what it is) and \\.\PhysicalDrive0 or \\.\C: (device and volume respectively, equivalent to /dev/sda and /dev/sda1 or similar).
Since a mount point relies on the device being mountable in the first place (which means it has a filesystem the OS recognizes and has a driver for), I'd be mildly surprised if there even is a mount point when a WP7-locked SD card is inserted into a PC. Quite possibly if it comes from an HD2, very unlikely if it comes from anything that ships with WP7 (since WP7 locks SD cards so that even things like the Filesystem ID can't be read).

The solution took me hours and hours and it worked.
Moved To HD2 WP7 Q&A
This is a device specific [A] answer, so it belongs in the HD2 WP7 Q&A section. Pleas refer to the mod sticky before posting in this section!
Or you can download partition managing software like minitool partition wizard and delete every partition you see on your SD card after putting it inside a SD card reader (IMPORTANT!) Works perfectly for me. If not then please PM me

Will this work on a SD card that is not recognisable in windows i.e bricked - Windows does not even see it.
This is what i have found:
I have Back to the Future [XBmod-Yuki] Rom running and DEV_STORAGELOCK.cab installed.
I had a friend who wanted to go back to WM6.5 but forgot to unlock card before flashing WM6.5 so he found himself with an useless card (encripted).
This is what i did:
With my phone (HD2 WP7) in standby, removed my sd card and put his encripted card in my phone then run the storagelock app and it starts and it seems it does nothing and returns to initial screen. After that i put my phone in standby again remove the encripted card and put my card again.
Then put the encripted card in card adapter and my pc recognized the card, used SD FORMATER with format adjustment on and the card is good again.
hope this help someone.
i recently flashed thors 1.7 touch recovery and when i rebooted my sd card wouldnt mount so i tried inserting it into my computer and my computer would not recognize my sd card either does anyone know how i can fix this its a 16gb sd card and I'm not trying to spend another 40$ for another one but I am thinking this one is toast.....any help would be greatly appreciated!!!!!!!!
As far as I know, there is no way to recover them. Once they are dead, they are gone. You can find the 16gb ones now for under $20 though.

You could try reformatting it. If that doesn't work, it's most likely dead.

if its a cheap card you might be lost.. i buy pny cards they have a lifetime warranty.. I Think the reason they do this is because i have NEVER EVER had a bad one from them. They are a cheaper memory provider that is often over looked for there superior quality.. Of course some other brands are backed just as well..
If your tab phone or computer will not read it . well i do not think anyone can help you.

Try Reformatting it through CWM recovery, then see if it mounts.

Try this formatter with uSD to SD adapter.
https://www.sdcard.org/downloads/formatter_3/
I have been able to recover photos from a corrupted SD card using the free version of this tool from Zero Assumption Recovery. Worth a try before you reformat.
My SD card was corrupted recently after my phone rebooted. All my photos and important data were recovered successfully after using TestDisk (developed by Christophe Grenier).
After recovering my files onto my laptop, I reformatted the SD card. I did it because the recovery process undeleted useless files.
Just do a Wiki search for TestDisk.
Note: As I am a newbie I'm not permitted to post the link.

I've never ever had such a bad experience but I really don't think that the card is dead unless you pushed it hard and crack the chip.If you use a windows PC ,once you plug the card (make sure it is properly placed into the micro sd adapter) then nothing happens ,as you say (it could be auto mount turned off ) press the windows key + R and type diskmgmt.msc.
This will open the disk manager of windows OS and you will be able to see all attached devices e,g HDD partitions ,USB thumb drives ,sd card and so on.If it s still not visible try to plug the card reader into another USB port.As a rule windows always informs you once you plug any USB device.If the device is not responding it gives an error
good luck.
Not always true... I had an sd card that just died... Neither Android, linux or windows pc recognised it... Windows recognised the sd card reader was attached but "was empty, attach an sd card"... 16Gb card to be tossed...
If the card is truly unmountable/unreadable and you really need to get data off of it, you could also try the service at recoverfab.com . They start where most free data rescue and formatting software can no longer help.

You may recover data from corrupted SD card with special recovery tool, see this useful guide: corrupted sd card data recovery
hope this helps.
recoverfab.com
Hi,
I tried using all kinds of different zero assumption recovery software and sd card repair software but with no look. I thought I wouldn't be able to retrieve any of the pictures I had on my sd card. That is until I found a company called recoverfab.com, they've been able to restore the majority of the files I thought I'd lost forever. I would certainly recommend them to anyone who desperately needs files recovering from an sd card.
My SD Card had the same problem and this, all of a sudden it was unreadable! I tried every method under the sun including trying to access it through an arduino and using SPI which is the alternative way of communicating with the device. I found a company called RecoverFab who said they could read the data from the memory chip even if the erst of the card was dead! So in a last ditch attempt I sent it over to them and the day after they received it I got an email and they had recovered 100% of everything on the SD card! I have never been so happy as it was all the photos from my girlfriends 21st! Superb communication and service!
I have been having trouble lately booting any sd build or nativeSD rom from sd card.
I have tried formatting cards in windows (including sdformatter) and linux (gparted), re-installing hspl, wm6.5 then magldr, but to no avail.
I get a message in 4ext sd recovery saying that the sdcard has only 1 partition of size "null", it doesn't recognize sdext or swap partitions.
When i try to run an sd build, it reboots (attached dmesg).
All this is despite the fact that wp7 is installed in nand and runs without any problems, this i think means the sdcard reader is not at fault.
I first reported this in here (and up to post #727).
Any ideas?
I have realized that WP7 works even without an SD-card inserted, so a working WP7 is not a proof that a card is functioning well. I don't have anything more, sorry
magldr's clear sd. have you tried that?
also, try using minitool partition wizard bootable disc to erase and wipe everything on the card, and recreate partitions and try again
I have copied the posts in that thread and posted them here, if the problem is resolved, I will delete those posts, to keep that dev thread tidy, as has gilbert32 (I might do it anyway)

Hi securecrt, it booted first time and after upgrading apps (not fresh install) it rebooted to bootanimation then went to lockscreen. I was able to play around with it for a bit and even managed to record a video (it doesn't play back on pc btw) but then gallery FCed and i got a reboot to magldr. Since then it doesn't want to boot past htc screen (attached dmesg).
I will try a fresh formatted sdcard and fresh install. Have to backup stuff first.
WP7 not affected though

Since trying securecrt's kernel on nativeSD, i have been unable to boot any nativeSD rom or any sd build on any of my sdcards.
However wp7 does boot ok, so it can't be my sdcard slot, which i thought might be the problem.
I am at a loss to explain it.
My 4ext sd recovery says that it can't mount the sdcard and does not show any partitions apart from fat32 of null size and B under free.
Please can anyone confirm this, and pretty please do not try to boot this until someone can explain what has happened

I have 3 cards, for nativeSD. None of them are working. that is 3 sd recoverys, 1 on each. all show the same. sd builds dont boot either. Something in phone is wrong.

Trying that while i type this. Last night i managed to boot a couple of nativeSD roms but after rebooting they refused to boot again. Also one of the cards showed normal partitions in recovery, then later i looked again and all 3 were only showing fat32 of null size.
Really confusing.
After leaving battery out for 5 mins, i looked in recovery and saw all 3 partitions. But couldn't boot sd build, nor nativeSD.
Another odd thing is the led on my card reader doesn't seem to want to stay steady, it keeps flashing intermittantly as if being accessed, i have to wait for it to settle before removing. After swapping out initrd.gz and zimage for another nsd rom to test, i look at recovery and get fat32 null again. Perhaps the problem is in pc, idk. New nsd rom doesn't boot either.
Edit; have attached dmesg of last nsd attempt, tytung's ics

I'd say it's time to go back to stock wm rom and try booting an sd or nativesd rom. if it fails, maybe try formatting a card with wm's format utility (which unlocks wp7's sd card) and try again. i'd say the kernel + initrd.gz have affected magldr and the card's mbr somehow

I think you are right gilbert32, something is wrong.
I just booted into ubuntu on pc and swapped out initrd.gz and zimage for another nsd rom, not booting. No flashing led this time. I had the phone battery out whilst changing OS on pc, recovery shows null still.
WM6.5, here i come again
Edit; I installed wm6.5 (had to do it twice, first time had an error box appear, not seen that before)
2 out of 3 cards were not seen by wm6.5, 3rd card was seen and i managed to boot a nativeSD rom, but after reboot recovery showed fat32 null and couldn't boot after.
I installed magldr and used fourth card i used for wp7. After formatting with sdformatter, deleting mbr, creating partitions with minitool installing sd 4ext recovery, recovery shows fat32 null again.
Tried to install twrp2.2.1.4 but it doesn't boot.
I think i am going to have to re-install hspl.

Thanks gilbert32, I flashed hspl, now i cant flash wm6.5, or reflash magldr, or run any nativeSD build (if i get one to boot it just hangs), so you could say it is serious
I have put my sim in an old(er) phone for now since waiting on calls.
I had formatted the card fat32 32kb clusters.
Gonna give it a break for now, i have been at it on and off all day. need to get things done.
It is odd that 4ext sd always boots regardless of whether anything else does.
Anyway, i am conscious of the fact that it is probably my hardware that is at fault. Until someone else posts in this thread with similar problems I will refrain from further posts here.
Thanks again.

well i'd try minitool bootable disc. only 40mb. and i always use it when coming from wp7. sd would usually not get recognized on wm without using it so try it.

Robbie, you're located in London right? I'm in Portugal, i can send you a hd2 motherboard for you to test, this motherboard is fully functional, the problem is that it overheats if you stress it too much, but at least you can check if the problem is your motherboard or not.

I have a cracked screen on my phone and was thinking of replacing the digitiser anyway. So I might take you up on your kind offer. I will see if anyone else has any ideas first:fingers-crossed:
Thanks mate.:good:
Robbie P, can you try installing a nand rom like cm7 only on nand?
and nativeSD roms hang on splash screen right? if so, maybe you can use adb. try mounting system manually and data too, then type stop and start
maybe sd isn't mounting well.
also use cd to /dev/block . is mmcblk0pX present there?
It seems that on first android boot after coming from wp7, i am more likely to be able to boot into nativeSD android. Subsequent boots don't work. But it only works sometimes. And the time i managed to boot into tytung's ics, i got a bsod after a call (attached dmesg, seems i lost sdcard).
It looks more to me like a hardware issue with my sdcard port.
I haven't tried nandroid yet. And when it isn't working, i can't connect to phone with QTadb.

you are right i think. sd card slot is probably somehow loose and sd is getting disconnected. maybe after booting tytung's ics, after the call, holding the phone and moving it in hand made the sd card get lost again. try booting multiple times, each time removing and reinserting the sd. ig it works more often, then that's your problem
I've sussed it
I found somewhere that says you can clean the sdcard slot with a piece of card wetted with alcohol (remove battery first). I tried it dry first and found dirt corresponding to the outside contacts of the card. It started booting, but gave a few errors and not all my SDcards showed correct partitions. So i tried wetting a new piece of paper card with GF's nail polish remover and inserting it in and out of slot (paper card should be same width as contact end of sdcard (if it is smaller, it could move from side to side and snag one of the phones contacts)).
It all seems good now.
Thanks gilbert32, yugoport & marvelz for your contributions. Much appreciated.
Looking at the dirt on the dry paper card, most dirt was on pin 8, some on pin 1 (see wikipaedia, tech details,transfer mode), so they only get used in 4-bit bus mode. Perhaps this is the reason why android wouldn't work, but wp7 does.
Lastly, i noticed that my wp7 card (16gb "old" card) has the sides worn down and metal is showing. The plastic from this could have covered the phone pins 1 & 8, or it could have been fluff
Back on android again:highfive:

It seems i posted too soon earlier, and it is back to showing null in recovery
Looking at the sd port, there seems to be a piece of metal sticking up around the area of pin 1 (rhs), so i think it has broken (possibly not helped by me prodding it with bits of card). Wp7 still works though. I took the case off and the port is soldered to the motherboard, so no chance of fixing it, for me at least.
Anyway, I have bought a second hand hd2 from one very careful lady owner (wm6.5 user), never been flashed, no scratches, looks brand new, no bad blocks and cheap. I showed my hd2 with cracked screen to the seller with wp7.8 on it and booted an sd android on the new one to check for connections etc. they were impressed but sold it nonetheless (they said "how did you do that?", I said that it was extremely complicated)
I now have a hd2 with wp7.8 and a hd2 with slim jb on nand dataonext, and I am a happy bunny again

that's good
a friend gave me an hd2 without screen/digitizer. it was supposedly fully working but misses those 2 components.
took it to a local store that is an EXPERT in fixing htc phones (called htc solutions ). they said they had to check if the motherboard was working. it was supposed to be okay. sadly, nope.
they sad it was damaged, so i'm taking it back for the battery

I know of a very nice person in Portugal with a spare motherboard :fingers-crossed:
Hi there, I was trying to flash a combination file on my s10+. then i saw a thread about flashing combination without etoken. to do that i need to delete bootloader with flashing uh.bin instead of sboot.bin. so did that. as a result my phone is dead now. and i follow the tutorial but no success. with multi downloader program it gives error that dram_el3mon not found. is there anybody who can help me about it? is there any other way to fix it?
not sure if this will work, but it worked on the S3's when they "hard bricked". If you can get the bootloader and mount it on a card that is the exact same size as internal storage, the hardware will look at external storage for a bootloader if the one on the internal storage is corrupted. Not sure if they still implement this as a boot strategy in their boot order, but worth a shot

Rufus. use it to mount the iso on the card. Rufus is free and i use it for pretty much every image i need to mount. IMGBurn does it too i think
