Ok, I had hard bricked my old Lenovo A6000 Plus. It was not even turning on. I was able to revive it, trust me it was not easy. I had followed many guides, one of which was http://www.dotandroid.com/android-root-guides/unbrick-qualcomm-mobiles/

I think I have mastered unbricking Qualcomm, so if anyone needs any help, message me here on XDA.

Unbricked Yu Yureka Plus

Hello, tirta.agung,

Greetings!!!

I am Apoorv, from Indore M.P. INDIA. I reviewed your thread written on Reviving Hard Bricked YU (QLoader 9008 Mode) through this link https://xdaforums.com/yureka/help/question-qualcomm-download-mode-k-t3068040.

As I am Holding same device and unfortunately it is showed following sysptoms :

1) When I start the Device, it automatically stucked on YU LOGO with continuously Vibrating.....

I given the piece to a Mobile Repair shop and after few days he says that device is dead. I asked him how then he said that due to File curruption @ 92% & he declared the device is not UNUSABLE. Only after that I realize that I made a big mistake as the Device given to him. Then After the Search on google I found YOUR THIS THREAD (above Mentioned).

I decide to go through your suggestion to get my DEVICE BACK in work. I downloaded ALL NECESSARY files (as per your Links) and start my work. My device is not showing :

1) RED LIGHT CONTENTIOUSLY ON

& I also found that my device is in (2.b OLD "Qualcomm HS-USB QDLoader 9008") MODE as per your thread.

When I start QFIL the PORT IS NOT SHOWING by QFIL while the PORT is VISIBLE IN Device Manager AS COM4 Port.

Also some time if QFIL detected the PORT the SAHARA : FAIL Error throw by the QFIL.

I Request YOU (ALL) please HELP ME OUT from this PROBLEM & also Help me to START MY BELOVED YU YUREKA PLUS (as normal)

Your Response against this is HIGHLY APPRECIATED.

Thanks in ADVANCE.

"Qualcomm Diagnostic"

Hi Tirtaagung,

I bought a Xiaomi Note3 Pro, and right out of the box I found it had a modded ROM (by the seller -XiaomiDevice-). As they were not helpful and wanted me to ship the phone back at my cost before they would refund (shipping would be about 50% on top of what I had already paid... to send it to someone who has already deceived me by selling me a product that was not what they advertised). Not going to fall for that one (word to the wize, stay way from xiomidevice-com).

So having a lost cause in my hands, I decided to risk changing the ROM myself with the little info I could find on the net at the time (Dec 2016). Results were not good, and I killed the phone in a minute flat.

My mistake was that I used the MIUI official ROM (latest global) which is provided to be applied using MiFlash but in FlashBoot mode, not in Download Mode. And unfortunately MiFlash did not complain about it, started the job, and at about 3% into it, complained that there was a shortage of available space and buffer...

Now my phone is stuck in "Qualcomm Diagnostic", (this is how it identifies itself to a computer), and does absolutely nothing when pushing buttons. It does turn on... but nothing on screen, just a slow blinking LED -in red-; until the battery goes flat). So, impossible to get it into ADB or to download mode again ('Qualcom QBLoader' mode). ...there is a method I see some people have done, involving opening the case, removing the battery ribbon cable for a few seconds, reconnecting, and then simultaneously hold the Vol + & - while plugging in the USB to the PC (all very well coordinated to happen together).

Anyone here that has been able to get this resolved?

Thanks.

Hi TirtaAgung/DarkSprite/Doomlord/Quakze.

Are the files "prog_emmc_firehose_8936.mbn", "MPRG8916.mbn", and "prog_emmc_firehose_8916.mbn" absolutely required for flashing a ROM to a Bricked Yureka???

About a month back I was a complete NOOB as far as Android is concerned. The only term which I had heard was "rooting" but I didn't even know the exact meaning!!! The Android OS (I didnt even bother to make a note of which version was already installed) was having some lag issues. I thought that its a simple matter of downloading a ROM and flashing it. I downloaded some Yureka ROM and started to flash it. Halfway through there was some confusing message and I unplugged hoping to try a different ROM. ........... BIG MISTAKE!!....... my Yu Yureka plus was completely BRICKED!!!! Tried connecting to my PC and it was detected as "QHUSB Bulk" device in "Other Devices" category in Device Manager. :(

To cut the story short I tried various forums including this one to try and revive my Yu Yureka plus Yu5510A. Tried different softwares like Qfil, YGDP, MiFlash, FlashAll.bat and every other software which was mentioned on any forum or thread. Qfil would throw-up the inFamous "Sahara Fail" error. I tried close to 20 differnt ROMS including coolpad device ROMS! Nothing worked!! When I read the posts here from some senior members here on XDA that "device specific" "prog_emmc_firehose_8936.mbn", "MPRG8916.mbn", and "prog_emmc_firehose_8916.mbn" are essential to revive a bricked Yureka, I almost gave up but kept researching.

The reason why I asked you the question is because I have Successfully revived my Yu Yureka Plus Yu5510A without using any of the above files. At-least to 90%. I say 90% because the IMEI is erased but it boots up without any issues. These issues are minor which I am hoping to resolve tonight. I was even able to connect via WiFi and install some apps too.

I request you or Darksprite or Quakze, DoomLord or any other experienced member to review my method to identify errors and suggest any changes, since I am still 50% NOOB! I will post a "Noob friendly" guide once you review the steps.

Thank you. Have a nice day!! :) :good:

Hi. I am also from Bangalore. I have almost revived my Yu Yureka Plus Yu5510A without those files. Please check my first post above.
[YU Yureka Q&A, Help & Troubleshooting] darkspr1te:
Yes, it is possible to recover without those files, as the 'switch to sd-card mode' is for convenience , the files written are bare metal arm code just to emulate the sdcard, in theory you can write direct the files you want from the first mode just as you write the .mbn part ,

however this is handled by the .hex part, when you upload that it's job is to setup the basic cpu/ram/emmc and give you a running device thats able to write to it's own flash, in that same theory it's possible to up load the first stage bootloader of the device (sbm1 or what ever it's name by oem) start it at the right memory address and boot the device, this is if the other parts of the boot chain are ok. sadly once you hand control over to the code you can only wait and hope.

I've suspected for a while that cetain "repair box's" do in fact use the device stage 1 boot loader and upload that, as it's signed it should run, then stich the usb port from USB mode to serial and stop the uboot loader, from there uploading the rest of the boot chain should be possible.

"without a RAW Image of your phone made by HDD Raw Copy Tools, everything will be useless. Just like the rawprogram0.xml, patch0.xml, msimage.mbn, MPRG.hex"

False, just the opposite, sorry.

And you cant use patch0.xml or rawprogram0.xml from same platforms, or mprg.hex (mbn), they all are device specific files, if this were true, i could unbrick every qualcomm based phone, but, im sorry, experience is talking.

Hi quakze or anyone in this forum, does your YU ever vibrate in 9008 mode?

Well now I'm trying to re-bricked my phone by flashing Coolpad 8675-A unpacked CPB files through QFil, the phone did not boot like usual, instead it is rebooted again to 9008 mode. And when tried to use QFil again, I got the same error like you do, fail sahara thing. Then I disconnected the phone from my computer, unplugged and replugged the battery, connected it again with my laptop, and run QFil, again I got fail sahara status, however the phone started to vibrate.

In curiosity mode on (I mean my brain), I then went to device manager and tried to unistall completely (I mean also putting a checkmark "also delete the driver sofware") the "Qualcomm HS-USB QDLoader 9008" driver, i got windows started to install this and I saw this on device manager (see pic):

[IMG="Wierd is't it"]http://xdaforums.com/attachment.php?attachmentid=3257835&stc=1&d=1428813889[/IMG]

I usually got this kind of configuration with my msm8x10 phone, and the QHUSB-BULK was supposed to be "Qualcomm HS-USB Diagnostics 9006".

And now after reinstalling qualcomm driver, I got this:

Make sure that the twrp image supports Yureka Plus yu5510, else your phone may not enter into recovery or may be hard bricked, till not possible to debrick
