Redmi 2 pro not working / partitions corrupted (phone bricked ?)

Hello everyone,
Instead of hijacking the topic of gkalen i'am going to expose my problem here, is my phone dead ?!
5 days after installing the miui v7 global rom my phone rebooted and got stuck at Mi logo.
Since then i dont have acces to xiaomi recover only to fastboot mode.
I cant use miflash because i kept getting the following error: [00000AFC]86d6ac8f 0.27 FAILED (remote: failed to write partition)
Mi PC suite isnt working either.
Today i managed to access TWRP recovery and as well adb shell, but installaing via recovery is not working as well and I get the following message:
E:Unable to mount '/data'
Same error using adb shell.
So I think the problem is linked to the partitions, let me show you thoses logs:
/dev/block/mmcblk0p24 /cache ext4 rw
/dev/block/mmcblk0p23 /system ext4 rw
/dev/block/mmcblk0p30 /data ext4 rw

Parted /dev/block/mmcblk0p24
print

I'am getting desesperate, anyone knows how to fix partitions issue ?

Actually i could need some help, if someone would be kind enough to run the following command with adb shell:
parted /dev/block/mmcblk0
print
And give me the output, here is mine and I guess i'am missing a few bits...:

Hi,
were you abel to solve your problem or have you received any reply to it? I also think that my internal SD card is corrupted and to install a new ROM I have to set it up again. I always get the following error messagre if I want to flash it with Mi-flash
"remote: failed to write partition" .
If I check it with fastboot in detail, I miss the partition with the name "partition". This is the first one which is flashed, but I do not have.
My phone is 2014813.
I hope somebody may help me.

Hello,
did any of you ever get this fixed ? Would be nice to hear the solution because I am faced with the same problem unfortunatly....
tia !

Did anyone here fixed this issue? Or is it hardbricked forever?

I never was able to repair it unfortunatly.

How can I Create a byte-for-byte image of my Internal Memory (from Recovery or ADB)

I am looking for a way to create a perfect, byte for byte, image of my internal memory so that I can recover data from the image in a safer way and from a copy where I cant destroy the original. I am really just looking to recover files I had under the /sdcard (USERDATA mount) however, since my partitions are messed up, I want to broaden the scope and capture everything. Can anyone point me in the right direction?
Help is greatly appreciated.

You would need to develop or find a developer who knows
how to create a very specific & special application to do that.
At the present time there is no applications that can do it.
You would be way better off to simply copy whatever good
files are in your internal memory to your computer because
any other way would result in many unusable files since
you said that the partition is all messed up.
By creating a byte for byte image of your internal memory
you would simply end up with a lot of unusable files since
your partitions are messed up.
Good luck, have a great day!

Thanks for the response Mr Junky. I can tell you I am fairly determined, short of hopping the NSA fence and demanding justice. Anyways, The partitions only matter so much since they do not define the files, the 1's and 0's do. There's tons of recovery software already, so no need to go that far, just need to get the data off my phone so it can be analysed. Square one is I grabbing a quality snapshot of the Internal Memory and putting it on my PC. At that point I can rebuild my phone without concern.

Does anyone know if the partition/sector offsets ever change, or are they static? I ask because I ran "Repair or Change File System" on /data which shares a mount with /sdcard (i think). If they are static, it wont matter that the partition table was rebuilt, the lost data should still reside there. I can simply use DD to capture /dev/block/sda18 to a file. As a side note, I'm really glad i had busybox installed.

I created the dd image of the USERDATA partition and saved it to the external SD card using the following command
Code:
dd if=/dev/block/sda18 of=/external_sd/dev/block/sda18.dd bs=4096
I then ran it against photorec which only returned 2 elf files. I will run it against testdisk as well, but I'm thinking either the data is gone or I did not use DD correctly.

In TWRP, when you go to "Wipe" -> "Advanced Wipe" you see a list of partitions, among them are "Data" and "Internal Storage". I wiped the "Data" partition as I thought "Internal Storage" would be untouched (since it was listed seperatly). Nope. Apparently they map to the exact same partition
Code:
/dev/block/sda18 on /data type ext4 (rw,seclabel,relatime,data=ordered)
/dev/block/sda18 on /sdcard type ext4 (rw,seclabel,relatime,data=ordered)
I used "Change File System" on "Data" in order to make it usable again, I must have destroyed all the data I was trying to recover. Had I build the image before I fixed the data partition, I would probably have recovered most everything.
Thanks go out to Samsung for enabling auto update by default and for thoroughly testing the update which blew up my phone! Great job guys : )

You need to use photorec directly on the block device, not a copy. Copies don't copy detached inodes, even with dd.

Everything I've read online negates that statement. however, I've yet to recover anything from the images I've copied, but I believe it may be due to hardware error. As a test, I put an photo on my /system mount and deleted the image. then I cloned the system block device and attempted recovery using photorec. this test failed to recover the file. so either DD is not copying the raw bytes or I am doing something incorrectly. I will try the same test using scalpel and also on another android phone.

Partition problems, no ERI, Unknown IMEI, no USB

I was attempting to troubleshoot another phone I had and it was suggested somewhere on here that I back up my efs partition and gave directions to use the command "reboot nvbackup". Well the result was not good. I've searched the forums for over a week and have decided to finally post as I'm out of ideas.
I followed radionerd's thread here and was able to get the Baseband back but I still do not have anything in "Hardware Version", and show "0" in PRL version, "None" in ERI version, "Unknown" in IMEI. The kicker is that somehow my USB no longer works when connecting to the PC. The cord works fine with other phones and it charges this phone but gives a "USB device is not recognized" error when connecting, under device manager it shows up as "Device Descriptor Request Failed".
I have been able to flash back to a stock ROM using TWRP (RUEOF1 is what I've been flashing) but that hasn't helped at all. I've attempted to copy mmcblk1 from the sd but it always fails, both from TWRP file manager and from the ES File Explorer. I'm guessing if I was able to flash a new PIT file I'd be good but I have no idea how to do that without having USB support. I do have working WIFI and SD card access, along with a good operating system.
I've tried a lot of stuff over the past week so I apologize if I haven't already mentioned it but I'm looking for help to see if anyone has an idea about what can be done.
Thanks!

If you unlocked your bootloader using the "standard method" then the "debrick" image you created on the SD card has a backup of literally every partition EXCEPT the ones that you would normally flash with Odin (or a ROM, e.g. boot, system, userdata, cache etc).
The reason that that unlocking method created a debrick image is so that people could save it so they would have it for emergencies. Such as the one you created.
Even the PIT data is included in a hidden partition inside the debrick image. But having a PIT file only allows you to re-partition flash memory, which you don't need; it's partitioned already. Re-writing the PIT is not going to magically recreate data inside those partitions that you erased.
Here's the bottom line: factory images, just like ROM files have NEVER had 100% of the partitions needed to restore the phone back to working condition. So there's darn good reasons to have backups or avoid wiping all of memory.
I think that @hsbadr had posted some debrick images taken during older ROM releases (N* series, I think) on his AFH (androidfilehost.com) site. Whether or not substituting some subset of those partitions (e.g. efs, persist, etc) onto your device will work correctly or not, but it's certainly worth a try at this point.
Skills you need to learn: figuring out byte offsets from the GPT partition table at the beginning of the debrick file to get the partition offsets in the "debrick" blob, and "dd" command options for grabbing exactly the byte ranges you want out of a single large blob file containing many partitions. (e.g. "skip=", "bs=", "count=").
Note also that the Unix GPT partitioning tools "gdisk" will let you examine the Primary GPT (UEFI?) partition table in the debrick image even though the secondary GPT is not present. That way, you can figure out the exact length and initial offset of partitions that you want to copy out of the debrick image into your device. (The reason for the missing secondary GPT is that the GPT/UEFI partition table indicates the presence of very large partitions such as /system, /cache, and /userdata, and the secondary GPT is always near the very end of the disk. Because the "debrick" image is literally a byte-for-byte copy of only the first 256 MB of the mmcblk0 flash device, there is no secondary GPT some 32GB "later" then the beginning of the debrick image.

I would start by restoring as few partitions are necessary e.g. "efs" and "persist" before I would bother with the others.
Example using data given above. (You should check your own work.)
efs partition: blocks 204800 to 233471 in debrick image, blocks are 512 bytes.
check length:
(233471-204800+1)*512 = 14680064
14680064 / (1024 * 1024) = 14 O.K.
so:
# dd if=/sdcard/debrick.img bs=512 skip=204800 count=28672 of=/dev/block/platform/msm_sdcc.1/by-name/efs
(or get clever and faster)
# dd if=/sdcard/debrick.img bs=1048576 skip=100 count=14 of=/dev/block/platform/msm_sdcc.1/by-name/efs
You should be pretty sure what you are doing with byte offset calculations with the "dd" command. Fortunately you are relying on the partitioning already present on the output side of things, so the worst that you could do is write misaligned garbage to a partition. So long as you don't do something incredibly stupid like overwrite a bootloader partition you should be OK.
cheers

Thanks for the reply, I forgot to subscribe so I just saw the post.
I have been able to copy all of the partitions from another phone but it hasn't helped. I'm now wondering if I'm missing a hidden partition.

How to install a new rom with bootloader loocked?

Hello I have a machine Redmi2 that does not boot, only boots with fastboot when I pressed the power off button ans Vol - button
I can execute fastboot commands.
For example:
fastboot devices

Click to expand...
Click to collapse
fastboot oem device-info
Click to expand...
Click to collapse

I could dowloaded various rom (official from xiaomi and not official like aosp-caf_wt88047_64-21-05-2017-eng.pirej.zip or xiaomi-miui-hellas-5.1_wt88047_V8_XTRVbeta2_7.2.24.zip) but I can install a new system in this machine.
First I try to unlock the bootloader with official method from Xiaomi but the result is error.
Now I try to boot with twrp and this is works.
To boot with twrp I cam execute this with fastboot
fastboot flash recovery twrp_arm64_3.1.1.img

And with this comand boots the machine with twrp
fastboot boot twrp_arm64_3.1.1.img

When machine boots I have access to external card from my PC and I can put the rom to try to install.
When try to clean the partitions I can not do it:
This is the errors

Click to expand...
Click to collapse
When I try to install RR-N-v5.8.3-20170516-wt88047-OFFICIAL.zip for example I can not install this rom.
Do you know if it is possible install a rom with bootloader locked?
Doy you know if it is possible unlocked the bootloader if xiaomi unlocker does not works?
Any ideas to install a rom in this machine?
Best regards.

i heard that redmi2 has unlocked bootloader and you are using twrp arm64 ? try official twrp and install rom ?

Thanks for your help,
I have downloaded the lastest twrp img from redmi 2, and I have the same problems.
Machine boots with twrp but I can not write in the internal partitions and I can not install a rom.
I think that I need unlock the bootloader to can to modify the android partitions but I do not know to do it.

try this one
when in twrp, open mount, give check to system, but uncheck "mount system partition read-only"
then try flash the custom rom
when tried "fastboot oem device-info" to my redmi 2 it also show "(bootloader) Device unlocked: false"
yet i can install just now, LineageOS

Hello, thanks for your help, but when I open Mount, only I can check Firmware, Persist, Micro SDCard and I can check Mount system partition read only.
I can not check System, Data, Cache and when I select Storage (Internal Storage (0MB).
I can use TWRP becuase I execute fastboot boot twrp-3.1.1-0-wt88047.img, ¿it is possible open twrp with any parameters?

Hello, thanks for your help, but when I open Mount, only I can check Firmware, Persist, Micro SDCard and I can check Mount system partition read only.
I can not check System, Data, Cache and when I select Storage (Internal Storage (0MB).
I can use TWRP becuase I execute fastboot boot twrp-3.1.1-0-wt88047.img, ¿it is possible open twrp with any parameters?
Regards, Julio.

I think that I can not install a new rom (offcial or unofficial) because the system I can not access to partitions /system for example and I think that system partitions is mmcblk0p23.
Do you know how I can modify my partitions to see in df -h and launch a new rom with twrp?
Thanks a lot,

Yes, you can recreate all the partitions and can even resize the system and data partitions. Head over to this link https://forum.xda-developers.com/redmi-2/how-to/wt88047-redmi-2-resize-partition-t3612933

Install original firmware

Hi. I had lineage os installed on my phone. Now i want to restore it to original. I can flash original firmware from there https://developers.google.com/android/images#occam without any error. The problem is during boot. It boot endless. I wait couple hours without any effect. I installed twrp and check partitions but it looks ok

If your stock firmware installed correctly you shouldn't have root any longer. How did you install TWRP? How did you install your firmware? flash-all.bat?

So when i figure out that stock rom don't want to boot i installed twrp from command line by
Code:
sudo fastboot flash recovery twrp-3.5.0_9-0-mako.img
to check partitions.
I installed stock rom by executing
Code:
sudo ./flash-all.sh

I see that i have 16G version but from partitions it looks like 8G version. Can it be a problem? How to restore partitions to original?

Your firmware should take care of everything. Did you edit the flash-all.sh? Take off the -w?
I've never used sudo before when flashing mine.

No i didn't edit files from google. Sudo is needed for fastboot execution on my system(manjaro). Then this command is run with higher privileges.

Have you tried a factory reset from within TWRP?
It's been a while since I've had a working TWRP.

I have some progress. I run stock firmware but with some additional steps. This is what i did:
- install stock rom
- install clockwork or twrp
- boot to clockwork
- start `adb shell`
- execute `mke2fs -b 4096 -T ext4 /dev/block/mmcblk0p23` in shell
But if i flash it again i need to do this procedure again. I don't understand why. I can't also do factory reset in twrp because it shows that can't mount some partitions.

"lightbox_toggle_sidebar": "Toggle sidebar"
}
I can do factory reset after calling `mke2fs -b 4096 -T ext4 /dev/block/mmcblk0p23` in adb shell

I started stock android and did some configuration. It looks that system is working. Now as a test i flash stock firmware again and i have boot loop again. Probably i need do the procedure one again. Do you have any idea why? And how to fix this? i see that cache also can't be mounted after flash stock rom so i did `mke2fs -b 4096 -T ext4 /dev/block/mmcblk0p22` and now it can be mounted. But why i need to do this? Why stock rom is not working? And this happen each time when i flash stock rom.
There is also such thing that if i don't execute `mke2fs -b 4096 -T ext4 /dev/block/mmcblk0p2` after flashing lineage os is showing screen that device is encrypted. Then i need to login do adb shell and execute mke2fs. This is wired that i need to do this every time when i flash device.

I solve my problem by following this instruction https://forums.androidcentral.com/n...3923-guide-nexus-4-factory-image-restore.html
I think that key was those commands:
- fastboot erase boot
- fastboot erase cache
- fastboot erase recovery
- fastboot erase system
- fastboot erase userdata
- fastboot oem lock
- fastboot oem unlock
