Hello rinfinity I flash the ROM last night. This time not need to short pin. Just plus in comp regonise as adb mode. Hit flash.bat then some file flash fail. Then I use other flash.bat with. Different is first format system userdata cach then flash other image. After success flashing reboot it stay in logo of cynagon. Can't goto recovery. I find that

modem partition of our YU's eMMC. If you want to and eager to get YU's GPT partition, all you have to do is just connect your phone with ADB, and type:

Code:

adb shell

su

dd if=/dev/block/mmcblk0 of=/sdcard/gpt.bin bs=512 count=65535

And, you'll find your gpt.bin in your phone's internal storage.

This statement in prost 1. After type adb shell it say no device. Su. And DD if.....of...... also error. And there is two gpt.bin file in the zip ROM of 8675-woi

Gpt main.bin gptback.bin. which is the need one or both of two file is in use ? And I find there is a dummy.bin in coolpad ROM that yu rom doesn't exect. Is it usfull ? Coolpad also HV two gpt. I think it is not same as 8675-woo gpt.bin. how can I flash the gpt ? Flash command I also use but fail. I think must be use with DD command. Sorry for so many question.
[YU Yureka Q&A, Help & Troubleshooting] rinfinity:
We can troubleshoot this method later. In the guide that i posted, there's no need to click flashall.bat

You are supposed to enter many commands like "fastboot -i 0x1ebf erase boot" one by one. Try that guide word by word and let me know.

========

Quoted from the guide: http://webtrickz.com/how-to-downgrade-yureka-from-cm12-lollipop-to-cm11-kitkat/

1. Download CM11 KitKat factory image “cm-11.0-XNPH05Q-tomato-signed-fastboot.zip” (fastboot flashable package) or from here.

2. Download fastboot.zip. It contains Fastboot & ADB files.

3. Extract contents of the both the zip files in one empty folder.

4. Open “Command Prompt” from the folder where you extracted all the zip files. To do so, open the folder and right-click while holding down the ‘Shift’ key. Then choose “Open command window here“.

5. Boot Yureka into fastboot mode – To do so, power off the phone. While pressing the Volume UP key, connect the phone to PC/Laptop with USB cable. The phone should show “Fastboot Mode” screen as shown below.

IMG_20150118_1617392

6. After connecting the phone, go back to CMD window that you opened previously and type all the below commands (ONE LINE AT A TIME).

Note: Enter the commands in the exact same order as stated below. Make sure to wait for “OKAY” confirmation after every fastboot command. (Use copy-paste to enter commands in CMD)

Code:

fastboot -i 0x1ebf oem unlock

fastboot -i 0x1ebf erase modem

fastboot -i 0x1ebf erase boot

fastboot -i 0x1ebf erase recovery

Yes already done

The problems is the gpt.bin. it s in front of the booloader. The phone stay in cyanagon logo can't go to the partition then can't go to the system.

What is gpt main gpt back.bin ? How to flash it?

Any suggestion? And phone battery alway 0 %. Is it due to the kernal ? Flash the factory boot.IMG can fix ?

Gpt is important otherwise I can't expaint whats wrong
[YU Yureka Q&A, Help & Troubleshooting] brickedmobile:
The unique problem

I bricked my Yureka while unlocking the bootloader and my colleague mistakenly removed the usb while unlock was in process (waiting for device)

Now going through the guides (10 days now) and analysis of phone symptoms,the problem is a UNIQUE one.

My phone lights up red dot everytime i connect it to laptop. Sometimes it goes into continuous vibration ( new 9008) but it hopelessly fails to read disk drive everytime and shows me only QHUSB BULK 9008 in port section (Old 9008).

QPST doesn't recognizes the ports also....please advise how should I go about it as service center is asking $100 for repairs.

Some help required. URGENTLY
[YU Yureka Q&A, Help & Troubleshooting] rinfinity:
I presume, you're calling it an unique brick because though it shows symptoms of "new 9008 mode"; still you can't access the emmc from your computer. Am I right?

Let me tell you, it's not unique. Even in new 9008 mode, the emmc is accessible in only some cases. Though, I'd suggest you try accessing it from gprted installed upon an Ubuntu OS computer, to be sure. If gparted can't see it- nothing can.

Having said that, the best method so far is to try booting into fastboot mode from sdcard (the guide can be found on xda-just search for it). From thereon, it should be like a walk in the park. :)

=======

Oh! And by the way, installing Ubuntu OS onto a pendrive might come in handy in the sdcard method too. Because, after you've done rescuing Yureka, you might need to reformat ur sdcard to be usable again. Gparted on Ubuntu can do that swiftly.

Try it, and let us know. Best of luck.:)

[YU Yureka Q&A, Help & Troubleshooting] rinfinity:
Tried 'lsusb' command (without quotes)? Does somethin appear as "Qualcom' and/or 'gobi modem' when giving the lsusb command?

Moreover, even if it gets detected, it's not necessary it'd appear in gparted. Though you've got nothing to lose in trying.

If it doesn't work, you can try the 'boot from sdcard' method- which, by far, has been the most (the only?) successful method.
[YU Yureka Q&A, Help & Troubleshooting] sahil432:
Some advice needed!

First read the whole story:

-Bricked the Phone: Was trying to Downgrade from RR Cm13 to Official Cm11 from Lubuntu but fastboot didn't load image so it justed wiped but didn't flashed anything.

- Revival:

A. First, Tried the given thread method: Always failed at Sahara Fail! (now I am on Win 7 x64)

B. Then, Tried the SD card method: Phone got boot loader (of CM 12) but it that method don't have the images of all partitions which were wiped like misc, panic, etc. So, the phone never actually completed booting, I found this after booting TWRP and it always uttered at a error, /persist unable to mount.! I tried to flash old images of not available partitions. But now It stucks on YU logo only.

C. Now, tried the pin 2 and 4 short method, but phone opens in charging mode (fastboot and charging screen still opens)

- Advice Needed (Choose one of these or suggest me another):

a. Wipe all again and try thread's method again.

b. Guide me a way to extract the non available the images from SD card method's image (this image is image of whole internal eMMC), so that I can flash the remaining partitions. OR anyone here can mail/upload them for me from their working yureka.

c. Flash whole eMMC with that backup.img from SD Card method (I don't know if this is possible from fastboot).

d. Any random or well thought method that I may have missed.

Thanks for reading the whole reply. :)
[YU Yureka Q&A, Help & Troubleshooting] rinfinity:
In my opinion, you should try A first with stock ROM.

If the problem still persists, we'll need to see if B and C are technically possible (i have a hunch it will be).

And just to put something for D, JTAG is the last resort (but economically unviable).
[YU Yureka Q&A, Help & Troubleshooting] sahil432:
Ok, i will try that first.

EDIT: I tried it with both ways, without shorting pins and with, both times phone is detected successfully, but same error: Sahara Fail. Just for info, now I have adb and fastboot drivers installed but I also tried it with a fresh installation of Win 7 but same error. :(

and

Just out of curiosity, what is JTAG? I have never heard of it.

You can't get "SaharaFail" error when using "Boot from sdcard" method, because Qfil is not used. Use this guide: http://forums.yuplaygod.com/threads...k-your-hard-bricked-yureka-yureka-plus.33515/

In short, since the phone can't boot from emmc, it looks for boot medium in the sdcard. Upon finding it there, it boots the OS from it. We'll use this to get into fastboot mode, and flash the stock ROM given in the guide. (If it doesn't go i to fastboot, try shorting pin 2 and 6.)

Hope this helps.

PS: JTAG is a device that connects with the SOC using the 6 pins, and canbe used to reflash the emmc directly.

The problem is driver incompatibility. Would suggest you to install Latest Miflash. While installing Miflash, the drivers get installed by themselves. (You don't need to use Miflash afterwards). Moreover, don't forget to activate test-mode.

Bro, I said I used QFIL method in both ways, without shorting of pins and with. But same error.

New Bug:

By getting into fastboot using memory card method and flashing TWRP. I tried to flash the official OTA CM12 (which would must contain all updated partition as of it is intended for CM11), but I couldn't flash it by TWRP and also not by official Cm12 recovery. Then I just tried to do sha1sum of file and what I saw is that, the sum changes every time (even when I didn't rebooted recovery or changed any thing). Does this mean eMMC is dead or corrupt on HW level.

Some Background of Bug: I have seen this bug, a few times when my storage is almost full or some big files are being moved. Like crashing of facebook on error of Memory block, whatsapp history corruption and apps not showing or always crashing until reinstalled and most common bug for me, rebooting of phone on un/installation of apps.

And bro, how can I use JTAG?

This is the exact same method. And this too lacks the image files which I told in my first post.

And if you are wondering which images and files, they are following : persist.img, panic.img, misc.img, modemst1.bin, modemst2.bin, params.bin, DDR.bin, and last fsg (nv.tar.bin).

How do I get this list? As you know I tried to downgrade my phone to KK from CM12.1. Downgrading wipes everything, and reflashes everything through fastboot. So, theses above ones were wiped and never got flashed as of fastboot didn't load images in Ubunutu (my 3 big mistakes here :( ). What I am saying is that: these above mentioned files are not available in SD card method as CM may not have released them.

And for info, after completion of SD card method, my phone is just booltlooped infinitely until I removed battery after 4 hours.

Hence, my last resort is if someone can extract and post images from existing working phones or eMMC images OR Sahara fail is overcame!

But, if you want to be spoon-fed, you can always go to Service centre. (Sorry for being rude, but it is annoying when people refuse to follow the recommended method, and yet still take time to complain). Please do whatever is suggested and report.
