In cm11 I've rooted my yureka. Then I've updated cm12s through OTA. After that it worked slowly then i did a factory reset and my yureka was not booted. But it is connected in fastboot mode. So I've unlocked the bootloader and installed 64bit TWRP recovery. Now my phone is in bootloop.... Any help please...!!!!:confused:

Need Help in finding backup.img file

Hello "tirta.agung",

Hi. My phone is not getting detected either as a storage medium or in PORTS section of the device manager.

In the section "2. REVIVING YOUR YU BACK", under "2.a NEW "Qualcomm HS-USB QDLoader 9008" MODE" in 4th step, you've mentioned the "backup.img".

I don't know anyone who has Yureka with them. So, can you point me to know someone or some place from where I can get that "backup.img" file ??
[YU Yureka Q&A, Help & Troubleshooting] tirta.agung:
Yes of course, you could recover your IMEIs using my guide, however the guide won't work if you change IMEIs that are not yours. Some people prefer to use QPST's "RF NV Item Manager", but I prefer to use qxdm as it can be use for dual sim.
[YU Yureka Q&A, Help & Troubleshooting] tirta.agung:
Perhaps you could talk with DoomLord about this. I don't have the phone anymore, and I just bought a Coolpad 8675-w00, but it hasn't arrived yet.
[YU Yureka Q&A, Help & Troubleshooting] tirta.agung:
Hi there, the brick.bat is for YU, not for CoolPad. And if you tried and it doesn't work for your phone, I guess CoolPad has lock your boot loader. But if you insist to use the brick.bat, you can download the aboot.zip attached to this post, extract the aboot.img inside it, copy the aboot.img to your internal sdcard, and use "dd" command to flash it while you are connected with ADB:

adb shell
su
dd if=/sdcard/aboot.img of=/dev/block/mmcblk0p4

When it says successful, then go to fastboot mode and run the brick.bat.

Please pm me for any update, because I'm also want to know about this. My new CoolPad 8675-W00 will arrive this week, perhaps on Friday, and I'm desperate to know whether I can't turn it to YU Yureka. I surely miss my old YU.
[YU Yureka Q&A, Help & Troubleshooting] nice_guy75:
No, I don't want to change my IMEIs, I do experiments with my Yureka, so only I am asking if somehow I erased my IMEIs, so can I recover my IMEIs using this method. Though I have also backed up my IMEIs using "Partitions Backup" application, I am not sure if it going to work or not, but something is better than nothing, lol.

Secondly, I have searched QPST's RF NV item manager's tutorial but most of the tutorials are for Samsung Devices, and the code which they have mentioned don't work on Yureka, *#22745927 and *#7284#, so how can I use that tutorial?

If you can help?

hey bro,

Do u found device specific files for Yureka from Mi4i fastboot rom ? i can't download that havy file though, can You (Or someone) please upload those small .xml .hex and .mbn files here.
[YU Yureka Q&A, Help & Troubleshooting] DooMLoRD:
hi everyone,

After a LOT of testing we were finally able to revive a bricked YUREKA!

I am waiting for more bricked devices to confirm the solution!

regards,

DooMLoRD
[YU Yureka Q&A, Help & Troubleshooting] quakze:
Very simple flash any rom with firmware-update folder of other device, but be sure to remove the first line from update script and use the update binary from Yureka. For example coolpad F2 ROM or Mi4i ROM, the device will be hardbricked for sure.

Update to CM12 and flash CM11s, the device will be Hardbrick.

BTW, really appreciated for trying to fulfill the promise.
[YU Yureka Q&A, Help & Troubleshooting] tirta.agung:
Yes that dial number, "*#22745927 and *#7284#", are device specific. Just download the "boot.img" in first post, or if you know how to unpack your boot.img, just put "persist.sys.usb.config=mtp,diag,adb" in your default.prop.
[YU Yureka Q&A, Help & Troubleshooting] nice_guy75:
Thanks for your reply

Are you talking about this boot.img and can I directly flash this img on Lollipop?

OR

I have to edit this boot.img?
[YU Yureka Q&A, Help & Troubleshooting] tirta.agung:
Yes, just download that zip if you are in YU's stock 4.4.4 rom, but if you in other rom, you have to unpack the boot.img of your rom and put "persist.sys.usb.config=mtp,diag,adb" in the default.prop of your unpack boot.img. 'Cos different rom, different boot.img, and that zip is only for YU's stock 4.4.4 rom.
[YU Yureka Q&A, Help & Troubleshooting] nice_guy75:
But I am on Lollipop?

Is it true that we can flash fastboot image of KK on LP if bootloader is already unlocked? I have seen a video in which a user flashed fastboot image of KK but when I opened its flash-all.bat, I have seen that he has added "fastboot -i 0x1ebf oem unlock" command in it?
[YU Yureka Q&A, Help & Troubleshooting] hugoprh:
HELPPP

So this was I have done to create and to try and solve this issue.

I was running stock CM12 and wanted to flash a different ROMs, so I tried to unlock the bootloader and using "fastboot -i 0x1ebf oem unlock" and without restarting the phone, tried to flash 64bit TWRP recovery, after this the phone no longer booted, but TWRP was booting, with a lot of errors of not being able to mount "/data" and other partitions. So I downloaded the CM12 offical ZIP file to try and do a factory reset, flashed using "fastboot" with the file "flash-all.bat" and here is where the problem started, this process failed, I think because there is a "flash-radio.sh" file where the "fastboot" lines do no have the "-i 0x1ebf" and because of this (I assume it's this lol), this process failed and the phone no longer starts, nothing works, tried in windows, ubuntu and a MAC at work, nothing is able to see the phone any more, the only sign of life I get, is when I remove the battery and connect the usb cable, the red LED from the phone turns on, but the PC still does not detect the phone, followed a recommendation I found, to remove the battery, pressing and holding the volume UP button + connecting the USB cable + connecting the battery, all this whilst the volume UP button is still being pressed and also did not work, no signs at all of life =(

Now found this guide, hopping that I would finally unbrick my YU, but from what I saw on the guide, the red LED lights up when the USB cable is plugged in, with the battery attached, correct? Mine does not, red LED only turns on if USB is plugged in when battery is off the phone and also Windows has at least be able to detect a PORT, correct? But nothing, not even with Windows in TEST MODE, no sign of life whatsoever =(

Not sure what to do more, any idea guys?

Can't return because I bought on eBay UK =(

My phone is terribly hard bricked. When i try to connect the USB or the charger all i see is a dim red light indicating its probably charging. I've tried all steps to revive the phone but in vain.

I tried the steps listed in the first page but with nothing being detected by the computer (not even qualcomm) i am at a loss. I have logged a complaint with the Yureka customer support and they promised to provide a replacement phone but no timelines. Is there anything else that i can try to possibly revive the phone ? I see couple of forums that talk about using jig cable to revive the phone and get it to fastboot mode. Has anyone tried it yet ?

Please help with suggestions on how i can get the phone back up. Hope there is something i can try once..
[YU Yureka Q&A, Help & Troubleshooting] nice_guy75:

[YU Yureka Q&A, Help & Troubleshooting] tirta.agung:
Well there is a test point that you can use to force the phone to go to 9008 mode, i've managed to do that with my fried YU. However, to do this, you need to open the back cover of your YU (not the battery cover) and it will automatically void your YU's guarantee. See the pic attached.

[YU Yureka Q&A, Help & Troubleshooting] darkspr1te:
Hi All,

I have been asked to look into this and offer any advice I can. I'am not promising any solution nor can I promise much time, my life outside xda keeps me very busy atm.

I do need to see some files to understand how the cm11/cm12 brick is happening, I dont have the bandwidth to download the complete zip's and major files so I as if someone could post updater-script from the cm upgrade zip files, this contain a complete list of what files are placed where.

Why do i need this? it will tell me which file/bootloader is being damaged allowing our debrick solutions to target just the area of damage.

bootloader hangs can occur in different stages, this will be noticed on devices that partially boot, as a example the device that dont show up in device manager but the red led comes on, this to me says at least part of the boot chain is occurring and it's initializing the charging system (sbl1 lets say) but then its crashing/panic on a later boot stage, shorting out ground of antenna point to the test point near the battery connector could be one of two things, you could be triggering the BOOT_CFG GPIO test point, see my debrick thread where i explain the 3 gpios used to control booting from sdx/hsusb/pbl/emmc as well as secure boot gpio.

I have read some of this thread but not all, I would like to catch up asking a few questions and splitting bricks into bootloader crashed/locked and pbl boot.

PBL boot users will see 9006/9008 PID's in windows, the system will see your device

bootloader crashed/locked will maybe see red light and nothing in windows at all.

has anyone searched for possible schematics and noted(confirmed) test points via gsm forums etc ?

do we have hex (arm file to switch protocol and allow writing to emmc)

do we have .mbn ( file to boot phone as emulated sd-card )

can we post a partition table near this post as it's important to identify the boot chain, partition type , GPT hard to hack than MBR based , with MBR you can write a new partition table and the data will still be there, GPT needs hacked tools to achieve the same.

I am going to assume it's GPT as most modern devices are.

can I also ask that the main forum dev's do the main posting's and avoid the usual " will this work on mine" "how do i fix my device, pse explain" post's , flooding the thread with OT posts or cries for direct support will hinder the situation.

For now, i will only be working via linux based solutions, so to work along you will need a usb bootable ubuntu/mint linux , activate persistent mode to retain changes across reboots or install via the wibi function if it's still there (i have multiple os's so i dont use that function)

Linux will also give us better log's, some devices detect issues and have a temp boot mode that switches off if it does not receive the correct init from the pc , this of course only happens if it can get to the boot loader that has the function.

well for now that's all i've got.

Nope, no coolpad 8675 Qualcomm variant on GSM Forums or any Chinese forums mention about test point. Even if you do a google search on "9008 brick msm8939), you will be directed to this thread. However, I managed to get Windows recognise my device by connecting some test points (there were some sparks upon connecting those test points). At first, Windows experienced a power surge on one of my USB port, and it recognised my device as an unknown device. But after restarting Windows, plugging and unplugging the battery, connecting the phone again to Windows while pressing the power button, it recognised my device as QHUSB_BULK with these description:

Hardware ID(s):
usb\vid_05c6&pid_9008&rev_0000&mi_00
usb\vid_05c6&pid_9008&mi_00
Compatible ID(s):
usb\class_ff&subclass_ff&prot_ff
usb\class_ff&subclass_ff
usb\class_ff

However, each time I leave the phone for approximately 30 minutes and do nothing with it, it restarted into QHUSB_BULK by itself with the same device info. Or if suddenly I disconnect the phone from PC and connect it again, Windows will recognise it as an unknown device. Here is the pic of test points that I use:
