We need more information. What ROM? What bootloader status? What happened when it crashed? What error messages are showing up when you try to flash a ROM or recovery?
Hello,
The bootloader informations : Unlocked / S-ON / 4EXT_Recovery_Touch
The rom installed : DHD_WWE_3.12.405.1_STOCK_rooted_by_nitr00.zip
I can flash another recovery (TWR, ..)
In wiping partitions (one hour waiting :
E:Unable to mount /cache
E:Unable to mount /data
E:Unable to mount /system
E: Failed to wipe dalvik
When trying the same rom :
the message error :
assert failed: write_raw_image("/tmp/boot.img","boot")
E:Error n /sdcard/DHD...._nitr00.zip (status 7)
Installation aborted.
After the TWR recovery i returned to 4Ext recovery, I did in 2 steps
1 - a wipe for factory reset/cache/dalvik,
2 - shutdown 5 minutes later
3 - i did a wipe for data/system and boot.
without shutdowning, i had an error failed to ...
I installed the RandomRom (145 and 5.00)
Firstly RandomRom145.zip
shutdown 5 minutes
secondly RandomRom5.00
then I flashed th boot.img
The rom was installed without errors.
When I booted it, I have the first white screen then I had a black screen for 1 or 2 minutes then the recovery tool was loaded.
Finally, I think that ma DHD is really dead.
I spent a day to arrive to this !!
Thanx for helps

First your DHD in continuously reboot, than You were unable to make a call and now this.
All this in period in one mouth?
I think you have corrupted eMMC.
No
I have 3 HTC Desire HD
First : in a continuous reboot,
Second : unable to make a call,
Third : the actual problem.
Best regards
Did you wipe everything after last ROM instalation (ROM + boot.img)?
Hello,
Yes I do everything (using 4ext Recovery Touch).
It takes a long long time to wipe : wipe data/factory reset; cache; cache+dalvik; dalvik cache; battry.
I had errors when formatting system and/or data, like :
formatting /data
E:format_volume: make_extf4fs failed on /dev/block/mmcblk0p26
E:format_volume: make_extf4fs failed on /dev/block/mmcblk0p27
best regards

I think it would be great to first check and to be shure if it's eMMC problem or not.
How to check this (one of example):
Try to install some other Recovery.
If you pass without errors turn off phone and pull out battery for few minutes. (if you get errors in installation, try few times, or try with different recovery, but just be shure that you not installing the same you allready have)
Put battery back on and turn on phone in recovery. Check is it really there and installed.
If you succesfuly installed diffrent recovery your emmc is working and you can fix it.
If you don't get errors, install it, and after restart you see that you have your old recovery, it's probably problem with your emmc. We can try more things to be shure.

Or you could try booting into bootloader and try using the erase and format options
like this
Code:
fastboot erase system
Code:
fastboot erase data
Code:
fastboot erase cache
Code:
fastboot erase boot
Same to the format
Code:
fastboot format system
Code:
fastboot format data
Code:
fastboot format cache
Code:
fastboot format boot
If these dont work, then am afraid your emmc is f*cked.
Hello,
Yes the emmc is out, I can't :
- erase or format system
- erase or format data
- erase or ormat cache
Thank you very much for your helps

[solved] TWRP - could not mount /data and unable to find crypto footer

Hi,
Nice to be here after so much years of reading !
My LG G3s (d722) was fine with Cyanogenmod 13 and encryption enabled. I've made a Titanium backup for my apps (& cie...) on the SD card, and reboot in TWRP 3.0.2-0, enter my password to mount storage, and I've wiped all partitions exept the SD card.
Then I've flashed the CM14 zip file, and get these error in the process :
"could not detect filesystem for /dev/block/platform/msm_sdcc.1/by-name/userdata, assuming ext4 mount: failed to mount /dev/block/platform/msm_sdcc.1/by-name/userdata at /data: Unkown error 200 unmount of /data failed; no such volume"
"Failed to mount '/data' (No such device)"
Since then :
- if I reboot into recovery, TWRP doesn't ask me the password to decryp the partition
- if I reboot in CyanogenMod ask me the password, but the tells me :
Decryption unsuccessful
The password you entered is correct but unfortunately your data is corrupt.
To resume using your phone, you need to perform a factory reset. When you set up your phone after the reset, you'll have an opportunity to restore any data that was backed up to your Google Account.​Then it reboot into TWRP
Any ideas ?
How could I mount ext4 partition in TWRP ? Or restore stock recovery ?
Thanks a lot for your advices
resolving !
Hi myself and everyone from another time,
I've resolved this mess by :
- installing LG drivers
- downloading kitkat stock-rom D72210d_00.kdz
- open LG Flash Tool 2014 and load D72210d_00.kdz, and start a CSE Flash
Then stard android 4, root it... etc
