Hi everyone,
I have manged to corrupt my MI3W's NVM partition. No iemi hence no network. Though, I have the .qcn backup but the QPST is failing to restore as the NVM is complete corrupted.
Now there's only one possible solution and that is emmc dump of MI3W.
I would appreciate if anyone who has a working MI3W could provide me the emmc dump of the same.
Following is the code to get the emmc dump of about 969 MB. You have to be rooted.
Open Terminal app and the type the following, it should take 10-20 mins
su
dd if=/dev/block/mmcblk0 of=/sdcard/MI3-emmc.img bs=512 count=2000000
Once done, you'll see a MI3-emmc.img file on the internal storage. The emmc can be compressed by winzip or winrar and the size should be reduced to 100 MB. Which you upload on Google drive easily.
Just be careful with the code, copy and paste if possible.
Awaiting you guy's positive response.
Thanks

Thanks again for the emmc image. I have been able to restore my iemi and got back network.
Fortunately, I had backed up my modemst1. modemst2, fsg and modem with dd command. Your emmc helped me restore my corrupted NVM partition and rest was done by the backed up partitions.
Mi3 has a locked NVM partition and I was trying to unlock the same. If you know how to unlock NVM then please share.
Thanks :good:

mmcblk0 is entire emmc but it depends on the size. In my case I've received 976 MB emmc provided by Klang, which does not contain sdcard/data etc as it's not the entire emmc size.
dd command copies the initial partitions which are there in those blocks. Refer to the attached pics of the emmc layout of Mi3.
I had tried Sahara & Miflash in download mode however, it didn't write the corrupted NVM blocks at all. Hence needed the emmc image of the size from a working Mi3.

I flashed the cm5.0.6 rom and definitely setup ext2 partition for my new 16G sdcard, but the app2sd always gray out, how can i fix it to make app2sd work?
Think it only works with ext4.
Thanks for the tip.
but when i try to ugrade ext2 to ext3 or ext3 to ext4 by using recovery 1.7, it always show some error info such like run "fs repair"
could u pls give more details for solving this issue?
much appreciated!
Create it from the computer instead. Did you run fs repair? The exact error codes are important to post, it can also help you search and see if anyone else had the same problem.
sounds like your partitioning may not have worked or your sdcard is not legit? have you confirmed it is 16gb?

Ok fellas, my nook color has been out of commission for over 2 months. I can boot from sd but not from internal emmc.
Sam has been helpin me but it has been difficult due to him being in a different part of the world. From what i've been told my emmc is corrupt and my partitions need to be rebuilt or formatted.
I have tried the different fixes here and still i am stuck on the N screen.
I am trying to return my NC to stock form.
I will let Sam chime in also. I know there are a lot of talents on this forum and pretty sure this can be fixed.
Thanks everyone..

Hi,
As Wendell said, I've tried helping him with his corrupt emmc.
The problem is:
The emmc semms to be corrupt, or at least some sectors of it. Wendell cannot return it, because it boots to CWR. That's the strange part, though the disk seems totally corrupt, it still seems to be able to boot. I guess some sectors and still working. But I don't know of any way to find out which..
This is what I know so far:
The internal emmc generally returns I/O error when trying to use fdisk or parted.
But, somehow, depending on the bs and count, I can dd /dev/zero to it.
Even after having dd zeros to it, it still seems to boot to internal CWR. So, the dd isn't working. Still don't know why, or how to remedy to it.
If someone could give us a clue or two here, it would be very much appreciated. I must admit I'm really no HDD expert..
Thanks!!
Sam

Have you guys tried this? Or has an internal EMMC rom been flashed?
Any idea how the partition became corrupt? Did you dual-boot?
Partition became corrupt after flashing a couple of the very first OC kernels. Not sure if thats what caused it but wouldn't boot past N screen. Since then i have been trying to fix it by doing the several fixes to no avail and possibly damaging the emmc even more.

Please correct if I'm wrong but i think i need the stock recovery for this method. Unfortunately, the stock was replaced with CWR and now i cannot even get rid of CWR off the internal. If I could do it again, I would not place CWR on internal but rather run it off sd. I installed CWR via rom manager because the sd method was not yet available.
Try option number 3 in the thread I made in the general forum. the clockworkmod recover + stuck at " " screen. Flashing cwm via rom manager can cause corrupted /boot partition

Woot , thanks for your response.
I have tried those methods to no avail. I can currently boot into CWR via 'home+N' but here is the crazy part, I cannot use the zip that sam made to remove CWR from emmc or even try to update to 3.0.1.0 via the CWR zip. My CWR on the emmc will not budge at all.
Sam, has even tried to erase my emmc totally from being able to boot to CWR just so I can get it looked at by B&N but CWR will not budge.
Excuse my ignorance, but will linux run off the sd card on the nook?
What about using something like GParted? Perhaps the USB bootable image on the sd card might work?
I know you are all trying to help. But please keep in mind that there aren't any obvious answers here. The emmc is corrupt. You can't flash anything to it.. and as I already stated, parted won't work either, it returns I/o error.
The only strange thing is that the nook still boots.. I can't understand that as the emmc lacks any partition table.
We need someone with hdd repairing experience. None of the answers found on existant threads will help Wendell..
Thank you.

The boot may be from real hardware/non-eemc rom.

I don't know if you will have any way of saving mmcblk0p2 and 3 to save your device specific information.

Sent from my SGH-T959 using XDA App
Here is what i would try.
First thing, get a cwm sd card setup that is bootable and has a decent amount of space so you can backup your emmc. The cwm sd card will allow us to adb in, but not worry about having any emmc partitions mounted (booting to a full android image would want at least the mmcblk0p2 partition mounted).
Make sure you have adb setup and working, so you can adb in once you've booted into cwm from the sd card. Make sure you know how to use adb pull and adb push to get files onto and off of the device easily.
Boot from the card, adb shell into the device. make sure when you are doing dd commands you are pulling from and writing to image files in a directory on the sd card, not on the emmc. you probably shouldn't even have any emmc partitions mounted at all.
Note: dd and bzip2 are both on the cwm 3.0.10 ramdisk, dunno about the earlier versions
I'd make a backup image of your emmc just in case things go from bad to worse:
Code:
dd if=/dev/mmcblk0 | bzip2 -9 > backup.img.bz2
This will take a while.
Now you'll need a MBR from someone with a stock partition table (i'm dual booting so mine probably won't work, otherwise i'd make one for you). Any volunteers?
Code:
dd if=/dev/mmcblk0 of=mbr.img bs=512 count=1
Once you have this file, just dump the image onto your emmc.
Code:
dd if=mbr.img of=/dev/mmcblk0
once you have a working partition table, you should be on your way to using the standard recovery techniques peppered throughout the forums.
btw, this won't fix any corruption in the extended partition table, that would take a little more effort (i'd have to read up on where/how that info is saved). Also obviously if it's a hardware problem rather than just corrupted data you have more problems than this will fix.
p.s. cwm loading witch a corrupt partiton table isn't that weird imho. the bootloader has barely over 400 bytes to load up the boot file and hand things off, it's probably not taking a close look at the partition map when it does this.
I know am probably being a stupid noob...have you tried the 8 failed boots?

Lol.
Thanks for all your input.
DD and fdisk return i/o error. DD only works if I use i.e 1M as BS.
It seems there isn't any partition table on the emmc.
I guess some sectors are dead. The idea would be to identify which ones and erase them.
Although simply being able to remove the bootloader would allow Wendell to bring it back to the shop..
Maybe someone has a clue as to how to delete completely the first X sectors of emmc..?
Thanks.

Did you read my post? It is exactly telling you how to replace the first sector of the emmc. you can source it from /dev/zero with a bs=512 and a count=1 if you really wanna wipe the bootloader, but better would be just getting it working yeah? all our nooks have the same partition map (unless we are dual booting) and that map is stored on the first sector. My instruction tell how to pull the first sector with dd, and how to push it back on. notice i'm accessing the mmc directly? not the partitions? so unless his hardware is bad (or the extended partition is corrupt too) then my instructions will work. He just needs a copy of the first sector of a working nook. I'd put mine up but i'm not sure it would work, i have two extra partitions from stock. It probably wouldn't matter, but i'm not 100% sure on that, so i'd rather it be someone else that makes the image from a nook with a stock partition map (the contents of the partitions can be whatever, as long as they are all in the same place as stock).
Hi,
Thanks. Yes, I read your post. dd, for some reason, only works if I set bs to at least 1M. I don't have the NC, but maybe Wendell could confirm that.
Wendell: go to "adb shell" and type [dd if=/dev/zero of="/dev/block/mmcblk0" bs=512 count=1] without the [].
Please confirm that this returns an I/O error.
But for some reason, using 1M or greater as bs works, but the bootloader still isn't erased.. it still boots to CWR..
I'm pretty sure all the I/O error i've had mean that there's a hardware failure.. But that's my opinion, nothing more..
Thanks.
I've been playing around and I screwed up my EFS partition. It will not mount to the folder. I have backups of my EFS files on my computer including the nvdata.bin.
I can upload the nvdata just fine and the phone will connect to the network upon reboot. The problem is that the block device which contains EFS data has been destroyed. This means every time I flash a new ROM i have to reupload my nvdata because the block that saves it is not mounted.
How do I rebuild/reformat this block of memory to avoid having to upload my nvdata.bin every time I flash?
See, that's the problem with being one of the top devs, nobody can answer the few questions you have...

That is for HTC phones.. They use different processors. It would likely cause my phone to freak out because of invalid architecture.
That's a classic, I'm sure there are some adequate fat.format methods but I always used the laziest one: restoring a dump of the partition itself.
I send you a link on twitter.
Thanks SuperCurio. I didn't want to scare people away before I got an answer... but here's what happened.. I used UnBrickable mod to upload BADA bootloaders to my Captivate. It treated my non-Bada formatted partition table as a invalid MoviNAND and tried to reformat it... It never suceeded in boot or whatever it was trying to do because the GPIOs in my phone are different and I could see errors coming across UART output.
When all was said and done, I used UnBrickable mod to restore my device but I did not have a block level backup of the EFS, only files. The EFS would not mount.
The solution was to get an EFS block from another similar device, put it on the SDCard, then type in a terminal:
Code:
su
dd if=/sdcard/efsbackup.bak of=/dev/block/stl3
Finally, I mounted my /EFS/ rewritable and copied my /efs/ backup to the folder.
You can reverse the "if" and "of" to make a backup of the efs before hand.
Everything was working properly until i went and booted NexusS bootloaders and unlocked... lol. I can always restore again.
Thanks Supercurio. I'll post a blank EFS partition soon.
So if we have the block backup...then if we mess up partitions. We just move those blocks back to original place.?

OK to start I have CM7.1 on my eMMC works fine for many months. I want to install MIUI.us_encore_1.9.16_Eng_Deo_ZipA_Signed_andmer ROM and it does not seem to work. Using CWM 3.2.0.1 flashing looks successful but when I reboot CM&.1 is still on the eMMC.
Tried doing a reset to default using EVRY technich suggested on these forums. No Go.
Using ADB I thought I would manually delete and push the system files over. I mount the system partition /dev/block/mmcblk0p5 and removed the existing files then pushed the new system files. But once I unmount and remount it reverts to the old files. The changes don't write dispite seeing the differences with an ls -al in ADB before the umount.
So I thought I would check the partitions and using fdisk via ADB. Deleted partitions 5, 6,7,8 and rebuilt them but when I write I get.
The partition table has been altered!

Yes, the first thing you do is upgrade that CWM. It is too old. You can get a new bootable CWM on my tips thread linked in my signature. Then I would reflash my repair zips as instructed in my partition repair thread. (Sounds like your partition 2 is ok, skip that). Don't forget to reboot between the repair and reformat. Then flash your rom with the new CWM.
Edit: oh, you changed the version in your original post to 3.2.0.1. That version is ok.

When you boot to your SD version of your ROM, can you save anything to the emmc media partition? I am wondering if somehow your emmc chip became read only. I have had that happen to my SD cards before, so it may be possible that it happens to your embedded chip. They act like they have been written to, but when you come back, nothing has changed.

OK Booted the SD with MIUI on it and was able to (or what seemed to be) save a file to the eMMC
BUT when I rebooted it was gone. It is like the write does not take on reboot.
I can even edit the file and it seems fine but the file is gone once I reboot.
It is like the changes are cached but not committed.
So I thought I would try creating the file and even edited the file from USB after booting the MIUI SD. Then when I stopped and restarted USB connection and then the file was gone.
So Somehow the eMMC is readonly.
So how do I fix that?

That is exactly what happened to my SD. Looked like everything took, but take card out and put back in and changes did not last. This happened on my phone SD. No amount of trying different PCs, different device readers, formatting programs, partition managers, nothing would work. I could read and copy things from it, but never got it to accept anything. I just bought a new one. I know that won't work on your embedded chip.
You are lucky at least you can use your SD to run things. I have found there is no significant difference between running on SD and emmc.
Maybe someone else has some info how to fix it. I searched the web for a long time looking for solutions and found nothing. One other user here on XDA has reported the same symptoms on his SD, but I never heard of anybody that this happened to their embedded chip. Sorry.

In the case of your SD did you try burning an image over top?
I was thinking if I had a complete image of the eMMC I might be able to use dd via ADB to overwrite the whole thing. Back up the files from partition 2 first and then write them back once it was finished.
Thoughts?
Problem is where could I get a "good" image of the entire eMMC?

For my SD I tried everything. Images, formatting, partitioning, etc. Nothing could be written to the device.
You can make your own images of emmc by dding in reverse and write emmc partitions to your SD via adb. But if it is truly read only like my SD was, you will be able to write nothing back no matter what tool you use.
Yea I was hopping I could get an image of the entire working eMMC that included the partition tables and see if that worked in case the problem is related to a setting in the partition table.
Hello,
I think it would be interesting in the next buid of CM10 implement FUSE.
For those not familiar with FUSE, this makes the EMMC (Internal) and DATA partitions are one.
FUSE is the standard in new android devices like the Galaxy S3.
With this gain in space, since both would have 6.7 GB of user data (photos for example) and for applications.
This would require using a repartitioning and as it should be, we could give more space to the partition and Partition System Cache.
I made a build with FUSE on, and doing great. It should be a standard in CM10 for P990.
A greeting and I apologize for the translation.
no thanks, i really like having my system and sd card separated...

Sorry, SDCARD is the defaul name for internal.
FUSE = (Internal EMMC + DATA)
Without FUSE:
Partition 8 = DATA [1,5GB]
Partition 9 = EMMC [5,3 GB]
With FUSE only have:
Partition 8 = USERDATA [6,8 GB]
The user can see 6,8 GB in Internal SD
Sounds good but will it work,
If you want the CM team to pick it up you will have to talk with them directly.
Good luck

Only change two files, and they here in the p990 repo.
Other solution is clone a p990, change two files and create a p990-fuse repo.
why would i fuse those two partitions? they are fine like they are now.
if i want to format the internal storage without affecting apps data i can while i'm using the actual partitions set, i cannot with the new mixed one.
this fuse leads what advantages?

- You can format only DATA, and can format only EMMC too with FUSE with CWM.
- When you use a file manager, you see the same that without FUSE but you have 6,7GB.
- You can install 6,7 GB of APP.
- FUSE is ANDROID standard. All new Android devices use FUSE.
sounds great. make a flashable zip, we'll start using it
Sure
I'd give it a try i have a device i can use for testing
Ok,
I'll upload a zip with NVFlash and partitions.
Anyone can upload misc and lgdrm partitions?
Open Terminal
su
dd if=/dev/block/mmcblk0p3 of=/storage/sdcard0/misc.img
dd if=/dev/block/mmcblk0p6 of=/storage/sdcard0/lgdrm.img
After doing this, in the internal memory of the device, there should be two new files: lgdrm.img and misc.img.

I hope they are useful
Very thanks Chuck Bartowski
But your lgdrm.img is empty when mount.
This occurs when you have used nVFlash, not a problem, but I would like the original partition lgdrm compare with mine.
Anyone can upload original misc and lgdrm.
Thanks.
What about usb storage(internal storage) mounting after FUSING ?
Will it work as before ?

and still - i like it as it is
i still have 2 partitions with 6,8 GB total - but i can keep things more organized with 2 partitions than with one...
for me it's just like having 2+ PC harddrives - one only for the system, and other disks for the other files...
how do I flsh this to files with nvflash?
instead of fuse of internal memory(1.5gb) n internal sd(5.5gb).....
can i have fuse of internal sd(5.5gb) n external sd(i have 16gb) so that i can get...
external sd---21.5gb....
imo 1.5gb is enough for app data but 5.5gb is not enough for sd data files(nova 3 almost 2gb)
i hav mounted my externalsd as internalsd so that sd data files are saved in ext but 16gb not enough(game addict)...
hope u can help..thanks
