If you experience battery bug, does this mean you have unbricked your YU using previous methods? If you do, could you confirm to the forum that you atleast unbricked the YU, cos fixing the battery bug is tremendously easy.

How did you bricked yours?

I bricked mine while flashing CM12
[YU Yureka Q&A, Help & Troubleshooting] quakze:
If it is dedecting as AO5510, then it is soft brick.

Attach USB cable to your pc and then to your device. The LED near the speaker at the top goes red.

As soon as the LED glows keep the vol up button pressed. You will see the fastboot screen.

Now type in terminal:

fastboot -i 0x1ebf oem unlock​

fastboot -i 0x1ebf flash flashthefsatbootimage​

Ok, first, does windows detects your phone? Go to device manager, do you see QHUSB_BULK on it when you connected your phone?

By the way, before you connect the phone to laptop or pc, unplug your battery for 5 seconds, replug, and then connect to pc without pressing any button. Does windows recognise your phone? if it yes, then try the method in first post, if its not, then you somehow hardware bricked it.

Connect the USB cable to the device (don't press any button/key on the device)

Stay away from Qualcomm drivers for now. Lets first determine what device is getting detected in device manager and its hardware id, then only we can ascertain whether Qualcomm drivers will work or not.

When device is not connected:

Uninstall all the items nested under "Android Device" / "YunOS" from device manager. Right-click item > Properties > "Driver" tab > Click "Uninstall".

Device manager > Action > Scan for hardware changes

Device manager > View > Show hidden devices

Post screenshot

YunOS [from Screenshot_(47).png] was showing up when the phone was connected or disconnected?

Now try post #124 again: http://xdaforums.com/showpost.php?p=60197539&postcount=124

One very important tip for all Windows 8 or above (64 bit) users, you would need to do additional step to disable driver signature enforcement in addition to enabling test mode. Follow the procedure on this link -

http://www.howtogeek.com/167723/how...8.1-so-that-you-can-install-unsigned-drivers/

This could be the answer to most users why their bricked YU is not getting detected by Windows since Qualcomm drivers are not signed and whql certified. They would need this additional workaround to get them working.

I did it using fastboot.After it when i tried to start my phone in recovery mode it didn't started "flashed Yu logo and then died" .But when I simply powered it on it did get on.After it I tried to install stock recovery back as I thought that the twrp recovery might have got installed but wasn't just working.Again I did it by using fastboot commands.This time when I tried to start phone in recovery mode,again same thing happened,so i tried starting it normally and now it even doesn't start normally.It just flashes Yu logo and dies.while I connect it to pc using USB it constantly keeps restarting .I read this forum and tried figuring out my problem.I was gonna try the hard method but in my device manager,it is shown as portable device and it says that the device is working properly.Mini-partition tool doesn't show any disk drive for it.I can't access recovery or fastboot..Need urgent help

Hey there i'm the owner of a Coolpad F2 Full HD i was invited to contribute on this tread but my phone is flashed with another rom wich has nothing to do with yours; the only informations i can give to you is that since I also broke my screen and i've been forced to change it are 2.

My phone is a FULL HD ONE and is 1920*1080, RAM 2GB, 16gb STORAGE, Android 4.4.4 Kernel, named Coolpad 8675-FHD

1. I Opened my phone to fix the screen and my motherboard is marked as 8675-W00 instead of 8675-FHD (so i suppose that these phones are exactly the same hardware)

2. On this page here https://www.facebook.com/tw101.rom.factory you can find the original stock roms for Coolpad Devices.

Hope you are going to solve this problem.

If you need some files i've a rooted coolpad f2, ask, but i won't brick mine :)

There are also recovery images on tw101rom factory

I think mine is the dumb question...

Looking at the thread, i read that Denpasar-Bali unbricked 80% and went into bootloader mode, isn't it possible to flash another rom via ADB, i mean the recovery, the boot img and then the rom. Maybe there's a lot to try yet on it and looking in the bat file format.bat i see there is a command to flash the IMGS of boot, recovery, system, so why is 20% bricked?

Or am I missing something in the thread?

HELLOO....

[YU Yureka Q&A, Help & Troubleshooting] ᴿℓᴚ:
#124 = Post no. 124 of this thread!

Everytime you try connecting the device to PC, you've to remove the battery for > 5sec and re-insert and then connect. After that, you've to look for the device in Device Manager. If it doesn't show up installing drivers wont help. Remove external memory card & SIMs if inserted and try again.

For now, it looks like removing the battery for 5 sec and re-inserting is not doing the trick for users flashing 32<=>64bit images or messing up during/after L update.

Some key combo might trigger the Qualcomm's HS-USB enumeration. The reason why I told you to do that.

Check the references below about MSM8960 boot architecture. PBL (Primary Bootloader) Error Handler sequence:

Once PBL error occurs, it goes to error handler

PBL will log the necessary log information into the RPM code RAM

PBL will go to Emergency Download mode if it is not disabled by fuse

PBL will try SDC port3 recovery first [read partition image from SDC (Secure Digital Card) i.e., your memory card]

If failed, PBL will go to

HS-USB Emergency Download mode

In Emergency Download mode, PBL will enumerate the HS-USB and wait for the packet from HOST

PBL will retrieve eMMC Flash programmer and authenticate it

Once load and authentication are passed, system will jump to the Flash programmer start address

Flash programmer will execute and download the necessary boot images from host side

In HS-USB Emergency Download mode, the serial number/MSM hardware ID/OEM_PK_HASH read are supported in MSM8960

So you need to enter "HS-USB Emergency Download mode" instead of going straight to "Power down MSM" !!! The device with specific hardware id should show up in the device manager before you can do anything with it! Sorry, I can't explain in more details. I've brick it myself before I can comment more.
