@konankiakshay,
you should press download button first, and after that you should connect your phone.
Hope this helps.

bro, you haven't installed the drivers for your phone.
Install tinno preloader drivers (just google it & you'll find), and repeat the process.

thank you for commenting mate. got it back to life.

Can't flash TWRP

Hi. I decided to flash my Honor 3c with Cyanogenmod 12.1. My problem is that i need TWRP (now I have CWM) but i can't flash it to my device. I try to do it by SP Flash Tool, but after i connect my turned off device, I get this error:
BROM ERROR : S_BROM_DOWNLOAD_DA_FAIL (0x7D4)
[H/W] Fail to download DA to baseband chip's internal SRAM!
[HINT]: 1. There's an cable communication problem between FlashTool and BootROM. 2. Target might be shutdown unexpectedly or target lost power supply.
[ACTION] 1. Try again. 2. Proceed H/W checking in download cable and target side com port. 3. Monitor if power-drop occured in target side.

Is your phone in bootloader mode? Hold Vol down+power to enter fastboot mode and then connect your phone to PC.
If you are already doing that or the problem still persists and have an unlocked bootloader(which I am sure you have), try to flash twrp manually.

When I do it, my phone just turns on normally.
How can I check if I have unlocked bootloader? I have unlocked it about 1 year ago, but I did full wipe yesterday.

Vol down+power should boot into fastboot. Turn off the phone, hold both until honor logo shows up, let go of power but hold vol down for about 5 sec more.
If still the same, Turn off your phone, connect USB cable to phone, hold Vol down and connect the cable to computer. It should boot into bootloader now.
If it can not boot into bootloader still, the last is to try adb but that is a bit lengthy.
In bootloader mode, it will be written on phone screen in red whether phone is locked, unlocked or relocked.
Wipe does not effect bootloader status so it's still unlocked imo.

Nope. Maybe I was wrong and I have never unlocked it? I don't remember, but I did something when I was upgrading my phone to Android 4.4.2

At least it should say, phone locked. Saying nothing is a phenomenon i never heard before but I usually go for newer versions. May be that's the case.
Anyways use adb to fire this command
Fastboot OEM device-info
To be sure if its locked or not.
To setup adb, download and install latest Android SDK, run the program and only download platform-tools.
Your phone is international variant and it came with locked bootloader, I am sure sp tools unlocked it coz otherwise CWM could not be flashed.
Right click platform-tools folder and select run command prompt window here and type the above command
If the bootloader is unlocked (it will tell you if it is), copy the twrp image to platform-tools folder and rename it to twrp.img and fire this command
Fastboot flash recovery twrp.img
And try to reboot into recovery after disconnecting from pc and simultaneously holding power+ Vol up.

edit: nevermind, i forghot about something...

You dont have your phone drivers installed. Google Huawei USB drivers and install them or use hisuite to install drivers for your phone.
After driver installation, do the same process again.
My bad. I assumed you would have drivers already installed

Hisuite is the best option. Even if that does not work (there is a chance of that), Google Kouch's universal drivers and install those.
May have to manually install dribers if nothing works.
Lemme know how did it go. Will get back to you in the morning if nobody else came along (but someone surely will before that).
Have a nice day/night depending on your time zone

I installed Hisuite and connected my phone. Windows have downloaded drivers automatically. And still the same...
But I forgot to tell you that when I connecting my switched off phone, my pc says "USB Device Not Recognized" (or something like that, I dont have english version of windows). Everything is ok when my phone is switched on...
This phone is cursed. I try to give up and stay on my current ROM, so I installed Nova Launcher, but setting it as default doesn't work :/
Thanks for trying to help me anyway.

I was awake just for your post. I think I got the problem. You need fastboot drivers imo but I would have to read a bit before I can suggest how to go about it.
Am busy tomorrow but will try to get back to you in the evening (GMT+5 time zone).
Can never be 100% sure but still I am confident, your problem has a solution. Just bear with me a day or two

Boot into recovery mode, no matter on which recovery are you on, and execute this command:
Code:
adb devices
And see the output, if it says something like:
Code:
**some_number** recovery
then it means there is no problem in the detection of your device by PC, if it does not, then check if the micro USB socket in the device is in good condition.
And I must ask: Are you able to do any operations on device via PC after connecting it?

Completely locked tablet needs stock firmware sm t817v

I have tried almost everything to unlock my tablet, but nothing wil work. I get various errors when i try to load pin bypassers, and FRP lock is enabled. I cant do anything to get this tablet working. It was supposed to be a display model for a local wal mart but the display wasnt set up. It is locked by the crossmark company and i have no idea where to look for help. Anything is appreciated

Have you installed the stock firmware then booted to recovery and factory reset?

You need to flash via Odin, you can't flash it with recovery.
You need to put the device in download mode not recovery.

Is this device running lollipop or marshmallow?
I'm afraid there's not much can be done with this tablet if it's stuck in demo mode.
The normal procedure is to install twrp then factory reset and then flash stock firmware.
However because this device has a locked bootloader you won't be able to flash anything custom such as recovery.
There's a chance that if this device is running lollipop you can try and root with kingroot then follow the procedure to convert to supersu.
With that you can install Flashfire then factory reset and install the stock firmware with that.

let it charge for 3-4 hours and check whether device power on.
by pressing
1.power button.
2.power button + vol +/vol-
3.power button. + vol+ +vol-
and seen whether you can get into recovery.

if your device is able to boot into recovery and it is being detected by PC then you have good chances of recovering your device.

S10 G-973F Android 11 Bricked

Hi guys,
I think I have bricked my phone definetley. I did a couple of bad things. First I disconneted the usb cable while flashing with Odine, then, worse I closed odin and the phone went into emergency recovery mode. I tryed to use Smart Swithc to revoer it but it daoes not connect with th W10 Pc. The only thing I can do is to switch off using power and volume down but then it restart atutomatically and shws the emergency recovery screen. I have tryed all te uttons combinations found on the web, but the stubborn piece od hardware does not hear me, Is there someone that cne help me? I am close to use a hammer...

Hey there, when the phone is in emergency recovery mode, does it show up in Odin? If yes, you can try flashing the firmware again. It should work.

No, it does not. When i connect it to the pc I can hear the connetion sound and then immeditely after the disconnection. In other words it connects and then it disconnects on its own. This happens either if connect trough usb B or C. Thanks
