Ascend Mate 7 ( TL-10) not booting

Hi friends
HELP needed!!!!
First the history
I purchased used Huawei mate 7 ( Gold Color, 32GB ROM, 3GB Ram) from a local guy. I noticed next day that wifi and Bluetooth of the phone are not working and also FM radio was not receiving any signal only blur voices and noise was audible . I thought that I must change the ROM to look whether the problem is software or hardware.
I downloaded b120 europian channel ROM and installed it but even then WIFI and Bluetooth were not working so i reverted back to original ROM thorugh nandroid Recovery ( i installed CWM Recovery before hand)
Now-----
the phone was charging fine till yesterday and its battery went off in the night . today when i tried to on it , it didnt show any sign of charging so i charge it for 2 hours , but even after that there is no sign of charging and phone is completely dead. I tried all combination of buttons , 3 button procedure but nothing happening.
phone was not dropped at all so i fail to understand what is wrong with this.
please help as my 475 dollar will go in blackhole.

MT7 TL-10 bringing back to alive after Lollipop softbrick

There are several threads and questions regarding soft brick of MT7 TL-10 after deleting of system in TWRP. Some people referring that installation stucks at 90 percent..i had the same problem..playing in TWRP and suddenly deleting/wiping system and all data..i was trying all possibilities mentioned in this forum..after many hours i succeeded to bring my phone back to business. Now i would like to share my knowledge gained during this process. I own an international version of MT7 TL-10..Before updating to Lollipop and wiping all data i was running B125SP02 firmware.

Here is step by step the procedure:
1. boot into bootloader( Vol Down + Power button with phone plugged to PC)

2. Download fastboot.zip from here: https://mega.co.nz/#!fZ4CCDJD!gSMMZG...l3Ro6kv7Rpz-40

3. You need to flash Boot and Recovery image in fastboot..Click thru the folder till sub folder named Fastboot..Press Shift+Right Click - Open Command window here: type - fastboot flash boot boot.img, press Enter..next command - fastboot flash recovery recovery.img..with this you have flashed boot and recovery images..dont close the command window and dont unplug your phone..stay connected

4. prepare you SD card, i used San Disk 64GB, any card 4GB+ should do the trick..Card must be formated in FAT32 otherwise your phone wont recognize your card..this you can do very easy way..
This small utility will help you: http://download.cnet.com/EaseUS-Part...dlPid=10982635

5. download the rollback package for M7 TL-10 http://consumer.huawei.com/it/suppor...x.htm?id=45463
copy dload folder to your formatted FAT32 SD Card....remember, you are still in bootload mode.

6.now go back to opened command window, and you type: fastboot reboot and press enter..the card is till not inserted.the phone will restart and now you can unplug your phone..you will get scree restart/wipe data/wipe cache

7.insert your SD card into your phone, press and hold Vol UP and Down at the same time and press Power button. phone will restart but you are still holding Vol Up and Down pressed for aprox. 10 seconds till Huawei logo disappears.

8.Update will start automatically , when update is done, phone will restart again till screen restart/wipe data/cache..you have successfully rolled back..stay there, do nothing, leave your phone how it is.

9.download stock Rom, i chose this one: http://consumer.huawei.com/it/suppor...x.htm?id=45462

10.remove your SD card, and on PC/Laptop delete the previous rollback update.app, but dont format the SD card..now copy dload folder from downloaded firmware, in this case B125SP02..
insert you card back into your phone

11.Now press again Vol Up+Down, keep pressing for aprox. 10 seconds and restart the phone with one Power button press..wait until the Huawei logo disappears..update will start automatically...wait till its finish, phone will restart and boot your system. And you are back again.

I guess, this quide should help also for TL-09 model, but with with Rom for your model.

Hope i could help you. If you have any questions, just PM me.
