[Q] Bricked Ascend Mate

Hello everyone!
One of my friend has a Huawei Ascend Mate, and he gave it to me. The phone was never modified (root, rom etc.). Like a month ago a lot of files just dissappeared from the device, and the apps unexpectedly closed sometimes. I've tried a hard reset, but it didn't help. 5 days ago, it just turned off by itself. When I turn it on, it shows a huawei ascend logo then an android logo and it stucks.
I downloaded the original B221 update, copied the dload file to the root of an sdcard, I entered to the recovery mode but it's not working, just shows some items in the menu. The problem is that it stucks before the usb driver is loaded, so I can't do anything via adb (can't reboot to bootloader), and the original recovery menu is useless.
BTW: when the recovery mode loads, it says this: E:failed to mount /cache (Invalid argument)
So I can't format the cache partition.
Is there any solution?

i also have same problem.. i think we need to re-partition the internal memory

I have a bricked HAM too. It boots up to the Huawei logo. If i connect to PC (or to the charger) the Charge LED is not working, Windows does not recognize that a device is plugged into USB. I can only hold the power button a few seconds then the HAM turns off and turns on itself till the Huawei logo appears. Thats it. Nothing more happend.
Is there a chance for this device?

Failed to mount EFS, Bootlogo loop N7100

Hello!
My Note 2 died a few days ago and nothing seem to help it live again.
It stays stuck on the Samsung logo when I try to boot it up and accessing the recovery gives me the errors in the picture (can't mount EFS etc...).
It was working fine and it suddendly stopped working.
I can enter download mode fine and everything seems to be ok there, the product name is there, System Status: Official, Current Binary: Samsung Official.
I tried flashing a 4.4 Rom via Odin but it fails giving me a NAND write error, I also tried to use Kies firmware initialization but Kies doesn't detect my phone, it gets stuck on "establishing connection". I'm sure my cable is working fine because I tried connecting another Samsung phone, I also tried all the USB ports and a different PC too.
I read that it could be due to EMMC memory fail and that it can be fixed by replacing the motherboard only, but I also read that people with that problem also get a blank Product Name in download mode, which isn't my case.
Is it really an hardware problem? Can I try some other routes?
It won't let me posts images so here's a link to the problem I encounter in recovery mode

Galaxy Note II (GT-N7100) Resuscitation

Its been a long time since I booted my Galaxy Note-II (GT-N7100) as I use an iPhone and Nexus 5 as my daily drivers.
The phone wont boot past the Samsung Galaxy Note II GT-N7100 logo. I am able to access the recovery and download mode as well, and I have flashed the latest stock rom from Sammobile using the Odin. The flashing was successful. however the phone doesn't boot past the logo. Also the phone will not power up unless connected to a PC, it wont power up even when connected to a charger and will immediately shut down when the USB cable is disconnected from the PC. I flashed TWRP 3.0.2 Custom Recovery using the Odin and tried installing CM 13 based Rom through the mem card, however the log reads patching image unconditionally and also that "Failed to mount /system" (invalid argument). The phone when restarted into recovery can no longer mount the /system partition. However on flashing the stock rom using Odin, the /system partition is available for mounting. The recovery log also shows MTP enabled, but my PC doesn't detect the phone when in recovery, it only detects the phone in Download mode. I have the Samsung drivers installed. Since the phone is not being detected in recovery I am unable to use the adb.
I am out of ideas and request your suggestions other than approaching a service centre.
If I can somehow access the phone via ADB, I might be able to check the memory partitions for corrupt units, and possibly create a custom PIT file to repartition and suit the available memory units.

Try this: open Odin, uncheck everything except f.reset time. Connect phone and flash stock ROM. When you see the word reset in the status window, remove USB cable, remove battery for a few seconds, replace battery, immediately boot the phone into recovery mode, factory wipe, and boot the phone.
Could the battery be defective or dead?

Thanks a lot.
Tried your method and finally the phone has booted into the OS.
Had to replace the battery with another spare one in the process.
However the phone is still not being detected by the PC unless it's in Fastboot/ Download mode.

When connected to a computer, does anything appear on the phone screen? If you're using Windows, nothing new appears in device manager?

Power off the phone and hold the volume buttons and plug in the cable. Now you are in download mode and should be able to flash
