You have corrupted baseband files ! unfortunately Karbonn and Cherry Mobile haven't release Source Codes or Kernel Version ! Without Baseband files you can not restore it ! you must update or re-flash baseband and then flash a stock or custom ROM to your Phone ! I Searched alot but no luck yet ! These Companies Don't obey the Law and kernel and source codes are still secret !
Some have been Compiling the codes ! You can wait or just go to service and according to my search it will take 45 days for you to take back your phone !
I think that even the Karbonn Company hasn't the source codes and only the Cherry Mobile Company has it !

Yes.. true . I have suffered from. It.. thank you

Blu Studio C Hd s090q stuck on logo screen

Hello everyone.
I have a Blu Studio C HD s090q stuck on logo screen forever.
I have downloaded this room here http://www.mediafire.com/download/d9bdr1dbw4qk9ic/BLU_S090Q_V07_REPAIR.rar
and SP Flashtool v5.1428.00 and MTK USB drivers which I have installed and restarted computer after that.
Followed this tutorial here: http://www.blogtechtips.com/2015/03...phone-flash-tool-to-flash-any-blu-smartphone/
The thing is after I click "Download" button of SP flashtool and then connect my device (without battery as suggested on tutorial) and press vol up, nothing happens.
What should I do? Could somebody give me a little help? I have bought this phone just 3 weeks ago.
Thanks in advance.
Edit: I just figured out what was wrong after many and many tries and I would like to share in case somebody have a issue like mine.
First off, I had to download and installSP Flashtool ver 5.1628 and MKT USB Drivers and I also installed MT65xx Preloader Auto-Driver.
After I installed all these, I had to manually install "MediaTek DA USB VCOM (Android)" driver to my computer, then as I had bricked my phone by replacing KingRoot for SuperSU, while following previous tutorials, instead of choosing option "Format All + Download" (which wasn't working at all in my case), I picked the option called "Firmware update". Hit Download > while pressing vol + button, plugged usb cord / cable > SP Flashtool started downloading and I released vol+ button.
That's it! If somebody have any doubt, feel free to contact me.

Did you installed MTK drivers?
In some cases you have to install it manually to your computer.

Don't format the phone. Try the FIRMWARE UPGRADE option!

There are several different BLU Studio C HD models. What is the MODEL NUMBER of your device? And what is the specific complete name of the ROM that you flashed?
Sounds like you flashed the wrong ROM.

You had a custom recovery on your phone? How exactly did you "download" the custom ROM to your device? You installed it from a zip using the custom recovery? Please explain.
Also what is the EXACT FILE NAME of the ROM you downloaded. Ron Genuine is not something I'm familiar with. Please answer the question I asked you. Without the exact file name, I cannot help you.

Hello Friend, I hope that even in these days I can respond. I have a problem with my Android ROM BLU Q S090Q / Android 6.0. I installed the ROM and everything perfect, I solved the Bricked of the phone using the MTK Droid Tools 2.5.3, the problem is that I could not rootearlo with any program (KingRoot, OneclicRoot, etc.) to be able to change the IMEI that I have it with another number and does not activate the Android's antenna. The Recovery of this Terminal is the original that brings the ROM that was installed, my question is: Will you install the TWRP you mention here and then load the SuperSU Binary 'to Rootearlo? What method can I use to robe my terminal? :silly:
I also read something on the Net about an Android ROM Nougat on BLU Studio G2 (Android 7.1.1 / CM14.1), is this true or is it a Fake?
Posd. I can not change the IMEI with the option "Engineer Mode" because in the terminal, the line inside the menu "CDS information" does not exist or is hidden, the other programs to activate it are NOT installed or blocked with an error message, I leave some captures to give you an idea.
"java.io.FileNotFoundExceptiion:/dev/pttycmd1: open failed: EACCES (Permission denied)/dev/pttycmd1: open failed: EACCES (Permission denied)"
NOT Root Imposible!: http://prntscr.com/gi9ez3

On first look, it seems like your phone is in bootloop and you need to flash new ROM after wiping the partitions correctly. But, then you are saying that same thing is happening when you insert this battery in another A6000. I think your battery has gone rogue due to some virus, just throw it away. Jokes apart, if another device is showing same behaviour then its almost 100% sure, that your battery has issues and need to be replaced. And, why don't you actually check switching on your phone by putting the battery from that another A6000 into your A6000.

I have checked with another battery, my phone works fine. But that particular battery is doing only on off continuously. But #important thing is , i don't think the battery has gone. Bcoz during the on off process, if i press volume down key, it shows lenovo logo and gets stock there. If the battery has problem, then how can be it stays on showing the logo ?? Confused ???
