Easy..
1. Have phone plugged in
2. do: adb shell
3. do: umount /sdcard
4. do: parted /dev/block/mmcblk0
5. do: print
6. do: rm X (where X is the number of partitions you see from #5)
7. If you have 3 partitions previously, repeat #6 3 times, but replace X with 1,2,3 respectively.
8. do: print (to make sure that nothing else is there, should be empty)
9. do: mkpartfs primary fat32 0 nnnn (where nnn is the number of MB can be found on second or third line of print command in #5. Example, if you have an 8GB card, it'll be like 7958MB when you print it. So put 7958 in place of nnnn)
10. mount /sdcard
Done or just use a card reader and Windows to delete all partition and reformat.

im no evo user, but if i choose wipe ext in the recovery menu would that get rid of the partition?

moved to the correct forum.

The easiest way that I've found to do it (if you're rooted of course and have a custom recovery) is that you boot into recovery mode, then go to the option to partition the SD card, then just set everything to ZERO (swap, Ext2) and voila! you now have a SD card that is back to normal..
at least it did for me...

Hey thanks alot everyone
just to note I have tried the wipe ext partition method before without success...

[Q] Cannot Partition SD ext

Hi Guys, bought a sandisk 16 GB Card, i am trying to format the various partitions so far:
1. Using Clockwork it creates an unrecognised partition after FAT Partition
2. Tried Ubuntu - will format whole card in either FAT or EXT 2/3/4 but will not create an ext after the FAT Partition (again unknown partition format after FAT)
3. Tried minitool partition manager - Can fortmat whole card in either fat or EXT. Cannot create an EXT after FAT - Unknown partition format
4. Tried ADB, will create primary partition 1 but not an ext partition after
Card id new and i believe genuine
any help greatly appreciated

Otherwise flash amonra-recovery, create an ext2-partiton and upgrade this to an ext3-partition with this recovery.

Have you tried Rom Manager? I used that to partition my 16GB sandisk

I used Ubuntu and it worked fine. Did you unmount the partitions in Ubuntu ?
Did you format the partition after you've created it ?

Hi, thanks for the replies, yes i unmounted in ubuntu but i seem to only be able to create one (working) ext partition but it has to be the full card, or multiple Fat partitions. When i create an ext after the FAT32 partition all partition managers & ubuntu see the second partition as 'other' and it is full.
When creating an ext with ubuntu it indicates 'cannot mount invalid argument'.
I have not tried using AMON as i was unsure if it was dependent upon GSM or CDMA type phones and also any issues with Amoled or SLED (my desire is SLED).
Tried Rom Manager an it does not even attempt to create a partition, indicates complete but nothing when i view partitions with either partition managers or ubuntu.
Lastly, tried via ADB but again it threw an error when creating the second EXT Partition, it creates a partition of sorts but again unknown and full.
In all cases, i cannot format the ext partition with any tools i know - ubuntu, partition manager, Esaus, ADB
Never had this issue with my 8gb Nokia card
Many thanks for your help though guys & girls

hi,
i read you try to do this with adb.. did you try the folowing cmd?
Code:
Step 1: Connect your phone to your computer via USB. Reboot into recovery mode.
Command: adb shell reboot recovery (this will reboot your phone into Cyanogen’s recovery image. Or power on phone when holding home button)
Command: adb shell (type this after your phone has booted and on the recovery screen. it should take you to a # prompt)
Code:
Step 2: Open parted to partition your SD card.
Command: parted /dev/block/mmcblk0 (opens parted and mounts your SD card)
Code:
Step 3: Check the size and partitions of your SD card. The print command will display this info. You can see the size of my SD card is 7969 MB (8 GB). I have 1 partition which is fat32. If your SD card is blank and no partitions are listed, you can skip to Step 5.
Command: print (displays SD card information)
Code:
Step 4: Remove all existing partitions. If you have multiple partitions, remove each one at a time.
Command: rm 1 (deletes partition number 1)
Command: rm 2 (if needed. keep going till all partitions are removed)
Command: print (check when you are done to make sure all partitions are removed)
more info howTO parted there
hope this help

The procedure should be this:
Insert SD, unmount. Create FAT, leave 1024, format FAT, format remaining as ext3/4.

Many thanks, tried this procedure again with the error message SEGV_MAPPER (Address not mapped to object) Aborted when i try to create EXT 2
Lost now

hi,
i look up the reason of that error, seems to be a bug from some lib.c inherited by parted but those are mention around 2006 amazing...
i know that the tut mentin ext2 as ext partition but why didn't try ext3 before doing this u can check out what does your actually partition says with
# fdisk -lu /dev/block/mmcblk0
give back the report plz

I suggest Amon-RA recovery.
It's very simple and fast
p.s: i don't suggest using Rom Manager, too much trouble

Hi Thanks for your help, i tried to partition ext 2, 3 & 4 but get the same issue regardless of partition type. I believe that the card may be a fake as all the transferring from phone to usb card reader has started to make the branding 'rub off'.
Therefore, i have sent it back and will hopefully get a refund or replacement.
many thanks for your time & efforts

okay, so soon with new one anyway you know where to go if need it

Recover images from internal sdcard

Is it possible to recover deleted images from the internal sdcard?
I deleted my images/videos by mistake (using Gallery). I haven't touch the internal sdcard since so hopfully I can still recover most of the deleted files. Since the internal card cannot be mounted as UMS, tools such as "recuva" won't work. Can I use "dd" to create an image of my internal card then use recuva to recover from the image dump?
My mount points:
/dev/fuse on /mnt/sdcard type fuse (rw,nosuid,nodev,noexec,relatime,user_id=1023,group_id=1023,default_permissions,allow_other)
/dev/block/vold/179:97 on /mnt/extSdCard type vfat (rw,dirsync,nosuid,nodev,noexec,noatime,nodiratime,uid=1000,gid=1023,fmask=0002,dmask=0002,allow_utime=0020,codepage=cp437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro)
I am not familiar with file system type "fuse" so I don't know if dd would work. Any help would be greatly appreciated.
Thanks.

Most it in a computer or laptop with sd adaptor and download pandora recovery. It's free and I've used it for in the past with sd cards. Works great

I think this only works if I deleted files from the external sdcard. For the internal scard, I don't think this is possible.
I have tried to do dd if=/dev/fuse of=/mnt/extSdCard/image.img but dd says that it cannot work with file system type "fuse". I have tried to use dd with other partition (user, data, system) and can confirm that it is possible to recover from the DD image.
As long as I can get the DD image of the /dev/fuse then I would be all set I think.

Just a quick update to say that it is possible to recover the files. All you have to do is to do
dd if=/dev/block/mmcblk0p15 of=/mnt/extSdCard/file.img
This is because from what I understand, the fuse partition is just a write-through for /data (which is ext4) with some security restrictions. If you have root access then you can dump the /data and mount it. Once it is mounted, you can use PhotoRec to recover stuffs.

[Instructions included] Need Internal Partitions (mmcblk0p1 to mmcblk0p5)

I've been trying to partition my External SD card so I can use it for Link2SD. I don't have an SD card reader so I tried using the adb + parted command. I was following this tutorial but then I realised that /dev/block/mmcblk0 was my Internal Storage and not my external SD. I deleted the first 5 partitions on there and my phone isn't charging nor turning on even though it's fully charged. Have I completely broken my phone?
Edit: phone shows up as QHSUSB_BULK in device manager.
Could someone please upload the first 5 partitions as imgs? I'm trying to use Ubuntu to try and replace the partitions I deleted. I'm running 4.16.1540.8 as my firmware and CM12 nightlies.
Use this command to save partitions as imgs on SD.
dd if=/dev/block/mmcblk0p5 of=/sdcard/dump/mfg.img
Just replace the mmc number with 1,2,3,4,5 and the image name to something that lets me know which partition it's on.
Thanks

bump

did you have any joy getting the mmcblk0 and if so can you upload it please

Please help, unbrick with sd card

Please help, I've bricked my phone, if anyone have backup of starting sda partition? In .img file .

If anyone can prepare file from own z2 play xt1710? Instructions is below, need root. Please help me
Do a complete factory reset on the phone. If a custom recovery is installed, use it to wipe data, cache, and internal storage.
While the sdcard is in the phone, run the follow commands via adb
adb shell
su
dd if=/dev/block/mmcblk0 of=/storage/sdcard1/backup.img bs=512 count=30535646
The size of the backup.img is around 16 GB, However, if compressed would be about 2 GB.
