I have a problem, and I'm dealing with it since this saturday. I really need my phone this evening so I really want help. My phone has since saturday a bootloop with every rom. Today I found out that it could have something in common with a error in the recoveryscreen which says it can't mount /data. CWM and the stock recovery both have this problem. Can please anyone help me? I'm really confused, because I have tried everything.
//I've discovered that the problem is that the /data partition is crashed. Is is possible to recreate the internal partition table?
install a stock rom then re-install cwm 5.0.2.7

I have done that already a few times.
Try flashing an ext4 converter, or re dd'ing an empty RFS format partition into place.
Already done. When I try to use ext4formatter in CWM it doesn't give an error, but when I try to do the data reset I will get an error again because it can't mount (and unmount) /data.
//And how do you add a RFS partition on the phone? Or do you mean on the SD?
Factory reset?
Have you tried doing a factory reset with Kies?

Thank you for trying to help, but your answer is stupid. It's impossible to go to Kies without a (working) rom...
I think I just found something interesting to know. I tried again to install Cyanogenmod 7.2 (ported by Phiexz) and in the Aroma installer I looked at the System Info. Almost everything looks fine, but this is not good I think:
Data Size : -1MB
Free : -1MB
(/mnt/sdcard) : -1MB
Free : -1MB

Are those partitions crashed? And how do I resize or reformat them back?
Which ext4 converter did you use?
Phiexz's if I remember correctly, uses the formatting tools included in the recovery. Mine has its own, separate binaries.
To reflash an RFS partition into place, you could use the dd command (carefully). Here's an empty RFS formated /data partition.
Or reflash back to the stock recovery and use that to format the partitions back to RFS.
Extract to your SD card and use the following command:
dd if=/sdcard/data.rfs of=/dev/block/stl13 bs=4096
Good luck,

I did use Phiexz's first yes. But I can't install yours. And where do I have to use dd commands? :$
What do you mean by "can't install mine"? Is there an error message or you're not sure how to do it?
If so, just apply it from the SD card like any other update.
The dd command has to be input through ADB shell while in recovery. So get ADB working if you haven't already.

I did know how to install a zip, but I tried 2 times and I think both were a bad download. Now I'm installing your Ext4 Converter.
// YOUR EXT4 CONVERTER WORKED!!! After a week without a phone it finally worked! Thank you so much!
Glad to hear that!
I had a similar problem of being unable to mount /system after installing a CM9 beta (can't remember which) and ended up solving it like that.
Hey guys i have a question relating to this dscussion. I have my gio running CM9 and i recently used BML5 to find my phone's unlock code. I have a nandroid backup of Rooted stock ROM, and when i tried to flash back to it, it said "Could format dev/block/stl13". I have the CWM 5.0.2.7 with RFS and EXT4 support, so it should work. What is the problem?
That's the thing; the exact behavior of those RFS+ext4 CWM builds when changing from one type to the other hasn't been very well documented.
I'm not sure they can format back to RFS properly.
You could always try that empty RFS partition set and attempt a restore afterwards.
What can i do if dd says, that it can't open '/dev/block/stl13': Invalid argument? I placed the data.rfs to the root directory of sdcard. Am I doing something wrong?
Can't mount /data
Hello, I have a bricked phone, and no idea why, and so far I'm unable to fix it. I've been waiting for an RMA so I can send it back to GSM Nation to evaluate and hopefully fix. My problem started when Samsung support told me to do a factory reset of my Samsung Galaxy S3, and it rebooted, then said it could not find or mount /data or anything therein. I have Not, repeat NOT, rooted my phone, it had the stock Android 4.3 OS and updates from T-mobile. The tech at the Samsung Experience Shop in the Best Buy store could not reflash it, when Kies tries to talk to the phone in Side Load mode it freezes or something, nothing happens. I downloaded ODIN 3 on Dad's win XP laptop, and in ODIN download mode the computer sees it as a new device with no driver to make it talk to it, and the drivers I've downloaded simply will not install. The installers die as soon as they run having done nothing. I am using my Samsung Chromebook to write this and have no Linux machine to work with. I am at a loss. Can you help me? Maybe I could re-install android using a microSD card?
I have the solution for data partition crash or any other partition
please do it with your responsibility but your phone is alreay bricked so it doesn't matter
hi every one i 've been through this problem for a long time and just yesterday hamdo lilah i discovered the solution it is by repartitioning your partitions with a pit file . i tried this method with samsung galaxy fit and it works even the pit file is for samsung .all you have to do is open odin included in the package then select pit file included then click start and there you go 'even if it doesn't show PASS ' after that just flash a stock rom ' or maybe any rom ' and that's it you are ready to go . i uploded the package on gulfup cause i have no account in mediafire enjoy if you face any problem just contact me or add a replay

What are all the steps involved from 4.3 bootloader locked to cm11?
Some threads are saying you can brick your internal partition if you don't unlock properly. I used to be a sammy owner( see signature). I'm new to the xperia world. I understand that root is required for TA backup and latest CM need 4.3 baseband. But 4.3 no root with locked bl?
Also, will flashtool flash device with locked bootloader to go from 4.3 > 4.1?

Also, What is your recommended method of unlocking the bootloader and why?
Please post any answers in a separate thread and link to it, so it can be made a sticky.
I am not responsible if anything goes wrong.
Go to http://xperiafirmware.com/8-firmware/40-sony-xperia-m-c1905, and follow the steps under "Upgrade to latest 4.1.2". This works on locked bootloaders too, and it even works if it is a downgrade, not upgrade.
Stock 4.1.2 is rootable with Framaroot's Gandalf exploit (search for it on XDA), root it. Then you can back up the TA partition, either with the flashtool you have downloaded earlier, or in some manual way. Make absolutely sure it went well before proceeding! I think you have read plenty of warnings if you have asked this question.
Then proceed as usual. Go ask Sony for an unlock key, unlock your phone with fastboot. Download the 4.4 ROM you wish to use, then flash the boot.img of it by
Code:
fastboot flash boot boot.img
. Then boot the phone into recovery mode using
Code:
fastboot reboot
and when it begins to boot, bash the volume up key a few times. Then install your new ROM from recovery.

Also, this is from experience, I have a C1905, which I prior upgraded with SEUS to 4.3. The procedure I wrote worked on it nevertheless.
Another thing that happened to me is that in the process my /data partition got corrupted. The "internal sdcard" lives at /data/media, and recoveries want to preserve this folder, so when they can't mount it and rescue files from it, they skip it, and the new ROM won't boot because it can't mount the /data partition either. So if you get a bootloop after installing the new ROM, try formatting /data AND the internal storage, there's an option in the recovery to do this.
When did your /data/ get corrupt? I read on xda that after boot loader unlock, you must boot a stock firmware to format /data/ properly, is this true? I'll post link to that topic when I have access to computer.(new user of xda app)

I don't know. All I know is that I did these:
Reflash 4.1.2 from flashtool
Boot it, root it, push a busybox on the thing
dd if=/dev/block/platform/msm_sdcc.1/by-name/TA of=/sdcard/TA.img
Pull TA.img from the internal storage to the computer
On phone: busybox md5sum /dev/block/platform/msm_sdcc.1/by-name/TA, on computer: md5sum TA.img, ONLY PROCEED IF CHECKSUMS MATCH! (They matched the first time for me. As a precaution I put them on my Google Drive along with the checksum, they'll be safe there, you should also find a safe place for your own backup in case you want to restore it later.)
Put the phone in fastboot mode, unlock it using the official method, then flash boot.
[*]Start recovery (bashing vol+), flash full ROM from the SD card, then flash Gapps too.
[*]Boot the phone, watch it being stuck on bootanimation.
[*]Pull the battery, start recovery again, wipe /system, flash ROM
[*]Boot phone, watch another 10 minutes of the boot animation
[*]Pull battery, start recovery, wipe everything, notice that /data won't wipe because it won't mount (WTF?)
[*]Do a bit of Googling, realize that recovery is afraid to wipe /data, because the internal storage (/data/media) is inside it, and precious things can be on it (for example the Nandroid backups, the ROM you were about to flash, family photos etc.)
[*]Use "wipe /data and /data/media" in recovery, this really formats the /data partition.
Flash ROM, flash Gapps, reboot phone, be happy with it.
I marked the steps with lime colour in which I am absolutely sure my /data was corrupted, and dark green when I only suspect it.
On second thought, it may have something to do with unlocking the bootloader in the official way. As far as I know, unlocking the bootloader destroys all user data on the phone as a security measure (say your stock ROM has a password you set but an attacker could flash an alternate ROM with no password to access all of your precious data. To prevent this you can't flash an alternate firmware without unlocking the bootloader and destroying sensitive data in the process). And as fastboot is a pretty simple and dumb piece of code (all it has to do is write the internal flash), I wouldn't be surprised if it didn't bother creating a filesystem on the /data partition, but instead just zeroed it all out. Their philosopy seems to be "if you know how to unlock the bootloader, you are a developer, and developers know how to format the /data partition". So, if my train of thought here is correct, my /data was "corrupted" in the steps marked with any shade of green, only this doesn't really mean "corrupted", it means "zeroed out with no filesystem".
The recovery's "wipe /data" command means: mount /data, and delete everything except the /media folder inside, because the internal storage lives at this folder, which most people don't expect to lose when wiping /data, for idiotic historical reasons.
So all zeroes -> no filesystem -> recovery can't mount it -> recovery pees its pants in horror and doesn't touch it, because it thinks "Oh my Glob, this partition does not contain a valid filesystem, but it may have a corrupted filesystem or one that I don't recognise, and formatting it could destroy my owner's data, which could be inside this hypothetical filesystem's /media directory. Which my owner wouldn't expect and then they would think I am a bad recovery."

I just re-read your question. I didn't use any stock software after unlocking, my recovery formatted my /data perfectly for me.

As far as I know, flashtool is just a GUI over fastboot when it comes to unlocking the bootloader, so it does exactly the same thing you would do with fastboot. It makes no difference.
What do you mean by "recreating partition with ADB"?
Are there any adb tools or shell tools accessible from adb to recreate partitions?

Hi,
my G3 and me have a small problem.
I wanted to update from official Cyanogenmod 12.1 to 13.0, backed up my data, etc.
First, there were tno Problems, but very fast battery drainage, and that my mSD card was now not "sdcard1" anymore but some numbers.
I tried fixing permissions in TWRP, had a bootloop. Updated TWRP (now 3.0.0 installed) and it worked somehow.
After one night it said process.acore quit unexpectedly. I had some crashes of the Google Play Services as well.
Then, it would boot, give me like 10 Seconds, and then jump to the boot screen of Cyanogenmod.
I tried to wipe data,system,dalvik. First there were problems with wiping dalvik, then there were problems with wiping system.
It says can't mount system: invalid argument. When looking around with twrp file explorer, the system folder is empty.
I would really appreciate your help!
You must check the partition type. Check if this as Ext4 or f2fs. In any case, try to repair the system of partitions from TWRP.
Okay, so:
Filesystem of /system is ext4
When trying to fix:
Repairing System using ef2fsck....
/sbin/e2fsck -fp /dev/block/mmcblk0p40 process ended with ERROR: 8
Unable to repair file system.
I assume it's because its ext4 and not f2fs?
btw I found something that may be important: when I try to wipe /cache, it takes forever.

Try to reinstall cyanogedmon 12.1 without wipes. Then, you enter again to the recovery and apply the wipes. I am not sure if for our model, cyanogedmon is compatible with the type of partitions f2fs and if is required a kernel with support for f2fs file system. You could try to changing the partitions (file system to f2fs), installing the rom and see if it starts but could cause a boot loop. Make a nandroid before making any changes.

Okay,
when trying to install the latest Snapshot of official CM, it just says ZIP File is corrupt. It said the same about an older build I still had on my PC.
When I try to flash the CM 13.0 build i had previously, TWRP just goes black and reboots (into recovery).
I also have to manually mount /system every time. If I try to mount /system again after dismounting it, it says 'failed to mount /system : Invalid Argument' .
This applies to all other partitions but the external SD Card.
When I try to change the file system to f2fs, it says OPeration successfull, but it didn't change anything, and the file system keeps being displayed as ext4.
Furthermore, i can't just 'Reboot Recovery' with TWRP- I have to take ot the Battery every time.

Which is your recovery version? If your recovery version is 3.0, you could try performing a downgrade of your recovery. If the errors persist, make an clean installation of the rom from LG Flash Tool (KDZ).

My Version is indeed 3.0. I had 2.8 before. Should I downgrade even further?
What would you recommend?
Besides:
I tried saving my files with the Terminal and [cp * /data/data/media/ /external_sd/Backup -r] and others, but it keeps giving me Zero-Byte Files.
Is this due to the Recovery version too?
You guys really are a big help! Thanks!

Ok but doing it woth cp * /sdcard/WhatsApp it keeps doing the same.
The only thing that matters to me now are my WhatsApp Images
I was able to grab the chatlogs but not more.
Sometimes it even copies all pictures (Like 8.000 files) but all of them are 0-Bytes.
I will try the downgrade tomorrow.
Thank you so far!
Were you able to resolve this? I have an identical issue. I was playing CoC on my LS990 with CM13 before it went black and now it always boots in to twrp recovery 3.0. The only thing that mounts is the external sd card.
I've tried the following and all fail:
adb push cm13 and then install from recovery
adb sideload cm13
lg flash tool via firmware upgrade, roms:ZV4, ZV6, ZV8
Is the internal sd damaged? Please help XDA gods. Thanks
So I decided to take my first steps to rooting, custom recoveries and ROMs and followed a stickied thread on the OnePlus forums here.
I firstly downgraded from Nougat to Marshmallow using the official Stock ROM. Afterwards, I flashed the recovery.img for TWRP from the official TWRP site. All is good.
I boot into TWRP and it asks me for a decryption password, I enter it and get "Incorrect Password". I try to boot normally and the same thing happens - weird. One member on another forum, from another question, suggested to wipe data through TWRP, and so I did. This cleared the decryption message through TWRP but then I got a boot loop with a simple message of "Decryption Unsuccessful". I press reset and the phone repeats everything.
Anywho, I flashed stock recovery and a fresh Marshmallow ROM which sorted my phone back to safeland.
Question is, how can I bypass all this? I followed the guide to the tee but no mention of this. I'm a n00b to flashing and only really know as far as the instructions on the OnePlus support page for flashing a stock ROM.
Use TWRP 3.0.4-1, it has decryption support.
If you are planning on rooting with SuperSU, use v2.79, not the first one that pops up when you Google "SuperSU". Not sure why, but the first link that pops up on Google directs you to an older version on Chainfire's site, which causes bootloops if you flash it on Nougat.
Other than the versions of the above files, the steps in rooting are the same as in the original guide.
I personally keep my phone decrypted, since I don't have anything super important on it. Not only do I not run into any encryption issues, the phone boots faster is decrypted. Decrypting does have its downsides though (you have to wipe your phone, also less security), so I would recommend that you research about it some more prior to deciding. There are methods of decrypting without losing all data though.

Thanks for the reply. I agree with you, I'm not fussed about Encryption and would rather have my device decrypted, the problem is I'm not sure how to decrypt it, or if it would be possible to revert and re-encrypt afterwards. As far as I know, Encryption is enabled by default on anything Marshmallow. In addition whether Decrypting would cause further issues down the line.
My reasoning for reverting to Marshmallow was Xposed and is the main reason I'd like to root with the possibility of flashing a new ROM.
In reply to your other points, I used the official TWRP from here if that makes a difference or should I be using the build you provided, surely if I can decrypt my device it makes it pointless for something with decryption support, yes?
Nonetheless, appreciate the reply!
The TWRP build from the official site is a little outdated, it is known to have decryption issues. Try the one from the XDA page.
To decrypt, you have to either root or flash a dm-verity-no-encrypt.zip that is floating somewhere around on XDA, there's probably a copy of it in the root guide in your first post. If you have no data on your phone that you mind losing (after saving a copy somewhere off your phone), the easiest way to decrypt is to go into TWRP and wipe your /data partition. If your phone is rooted or flashed with the no-encrypt.zip, the /data partition will not be encrypted the next time you boot.
There is a way to decrypt while maintaining your data, you can follow this guide. It involved saving a nandroid (saves all info in /data partition except /data/media, where all your media files and certain app data is stored). You can then save anything in /data/media by transferring it to your computer prior to wipe. You can actually restore a nandroid from an encrypted phone onto the same decrypted phone without having all your files encrypted. You can then transfer all your files from the /data/media folder back to your phone, though you'll need to give all the files and folders the proper permissions.
Once decrypted, you phone will remain decrypted until you flash OOS again, such as when updating. To prevent the phone from automatically encrypting its /data partition, you'll have to flash SuperSU or the no-encrypt.zip immediately after flashing an OOS ROM everytime you flash it.
If at some point down the road, you'd like to encrypt your phone again, that's really easy. You can go into the settings app -> secuity -> scroll to bottom to "encrypt". Clicking that option will encrypt your phone without data loss.
I personally have not had any issues after decrypting my phone. I can't speak for others though.

You can then save anything in /data/media by transferring it to your computer prior to wipe. You can actually restore a nandroid from an encrypted phone onto the same decrypted phone without having all your files encrypted. You can then transfer all your files from the /data/media folder back to your phone, though you'll need to give all the files and folders the proper permissions.
Once decrypted, you phone will remain decrypted until you flash OOS again, such as when updating. To prevent the phone from automatically encrypting its /data partition, you'll have to flash SuperSU or the no-encrypt.zip immediately after flashing an OOS ROM everytime you flash it.
If at some point down the road, you'd like to encrypt your phone again, that's really easy. You can go into the settings app -> secuity -> scroll to bottom to "encrypt". Clicking that option will encrypt your phone without data loss.
I personally have not had any issues after decrypting my phone. I can't speak for others though.

Brilliant. On a side note, I'm sure I did a /data wipe, which caused the boot loop I was having - weird. Anywho, I'll try the TWRP build you mentioned and see how I get on. I did watch one video which suggested to use the fastboot erase userdata as another way of unencrypting the phone.
Either way I'll give it all a try!

The TWRP build from the official site is a little outdated, it is known to have decryption issues. Try the one from the XDA page.
To decrypt, you have to either root or flash a dm-verity-no-encrypt.zip that is floating somewhere around on XDA, there's probably a copy of it in the root guide in your first post. If you have no data on your phone that you mind losing (after saving a copy somewhere off your phone), the easiest way to decrypt is to go into TWRP and wipe your /data partition. If your phone is rooted or flashed with the no-encrypt.zip, the /data partition will not be encrypted the next time you boot.

Thought I'd post a little update, I managed to install TWRP and Root. I used fastboot erase userdata which fixed my decryption issue - everything was working! Back to stock Nougat now but am going to be trying Magisk.
TL;DR of the problem: Can't mount the User Data Partition in TWRP, so I can't wipe it or do anything to it. Stock Recovery and Fastboot mode can't see it or mount it either, it's like it doesn't exists at all.
Is there any way to restore the default partitions?
How I created this mess: I tried to remove the encryption and failed (TWRP recovery and then wiping the data and userdata partition), so I tried flashing it using a Stock rom from another site (I'm not sure if I can link it since it's an external site so I'll just put the file name XT1710-06_ALBUS_ATTMX_8.0.0_OPSS27.76-12-25-15-2-4_cid50_subsidy-IUSMXLA_regulatory-DEFAULT_CFC.xml.zip) but the sparsechunk 6 (everything else was successful) failed to flash and I've been stuck on bootloop (it turns on, tries to load the OS and sort of manages but then it restarts itself) since then but now it's like the userdata partition doesn't even exists, it can't be mounted, can't be wiped, can't be restored (from TWRP) nor factory restored (STOCK RECOVERY).
So I am here asking any of you if there's a way to restore the partitions, specially since I don't really know if there's a way or the sizes/formats.
Also I've read about a blankflash but I'm not sure about the results I've found using google (it scares me to screw this even more). Could this fix my situation?
Please let me know if more data is needed (also how to get it so I can post it).
