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

Bricked my Life pure Xl 3Gb, Anyone can Helpme?

Hy Guys,
I have tryed to put the rom from Gionee Elife E7 on my Blu life pure XL. The installation occurs everything okay, but when i try to install the recovery, my phone reboot, and never more turn on again... I only can see the Gionee logo, but then shutdown after that. When i try to connect on the PC, just two drivers are showed to me:
-Gionee HS-USB Diagnostics (COM5)
-Qualcomm MMC Storage USB Device
I can enter in ADB mode, but i have no way to acess the internal storage...
Any help will be grateful...

when u installed the rom did the phone start up properly?

This look's bad man.
Try power on your phone then
Plugin into your computer.
Open adb then type adb devices
When your device is listed type adb reboot recovery
If IT doesn't boot in recovery mode then You should try flashing again the rom.
Something should work.

have you fixed it? perhaps i can help
if you've got fastboot (power + vol -)
you can fastboot (sort of like an adb) flash some system images and get your phone getting recognised by gnqc
you need :
ADB
boot.img from blu rom
system1.img from blu
right click on folder where adb and files are (they need to be on same folder for faster tipying)
write
fastboot flash system system1.img
fastboot boot boot.img
after that unplug phone, you need the drivers for blu, change cable from pc port and reconect to see if now it's recognized as a pure xl and check for the drivers.
It should install 2 com ports (hsusb, nmea) 1 adb, 1 modem and 1 storage
that is what i did to mine, hope it works on yours

Ok now, you can use GNQC and flash the rom and that will completely restore your phone
NOw if only i could find the blu rom for a 16gb blu

ok well im going to try pushing the elife 7 stock recovery and see what happens
tried that all it says is installation aborted .....

You have to to try this,that is how i have unbricked mine today.
power off your phone.
prepare your gnqc so you only have to press download when needed.
power on your phone then conect fast to PC ,then press download.
If IT doesen't leț You ,pres again and just try to see If IT works in different situations.
is a long shot but this is how i unbricked mine today.
fastboot doesen't work on this device,so You can't push anithing. i don't know hou this people are doing that.
If this metod doesn't work You shold try format system and data via adb . and after that gnqc should work.

He can't use GNQC because his phone's drivers arent insatlled, gionee blocks com ports, and fastboot does work on this device, you just got to flash it, i've been using it several times

A thing to notice is when you want to acces phone storage when phone is bricked You have to poweroff your phone and keep pressing power and volume+ untill some errors start appear in windows.
then You have acces to phone memory and You can paste anithing for later flash with recovery. You must Be very carefull not to format partition when asked !!!!!!
i have bricked my gionee 32 gb several times and always been albe to restore it so,no need to panic,some method should work for You too ,just have to find the right one.
And also,my phone is a rebrand of gionee from Romania,called Allview x1 xTreme,just like life pure Xl and i haven't encountered any problem with usb drivers, just used the one gionee provided. So this mai Be the case for You, i hope i am not wrong with this one.
Com ports are only closed in android 4.4 kitkat so If he didn't update he should Be able to use gnqc.
also You must observe that phone is recognised differently by windows deppending in wich state your phone is. powered off,recovery,or on bootloop. So that's why o have said that gnqc may work but You have to find that state when he is recognised the way that gnqc wants.
Sorry for long post i Hope those observations will help you.

Lenovo A6000 Softbricke​d---- Needs some help--Plea​se

Please note that I have done search and tried various solutions before starting this thread :
Hi My A6000 phone got factory reset and then I tried to recover some lost pics...but I was advised that my phone needs to be rooted first, so the software opened kingo root soft, It showed me the message that phone has been rooted and when it rebooted there was a notification of software update which I said ok and ever since then the phone is stuck on system recovery mode (not sure if it is called soft brick or not) and I have tried many things including choosing all the options starting from reboot system now, apply update from ADB, wipe data/factory reset, wipe cache partition, apply update from sdcard but nothing seems to work!!! oh I for got to mention on the top of the screen it says Androoid system recovery <3e>Kraft -A6000_S035_150507 and then gives all the option and i have tried this following :
https://boycracked.wordpress.com/2015/06/03/unbric​k-lenovo-a6000/
but some how for the first solution it keeps on saying download failed, emergency recovery download failed...anyways it does not work
I have also tried this
http://forum.xda-developers.com/chef-central/android/unbrick-lenovo-a6000-plus-lenovo-a6000-t3137247
but it has ADB killed (tried looking and installing adbfixer solution--it says it cannot finf adb.exe even though it is there)
Is there any soultion to this!!! Please help if there is one!

the link from boycracked (mentioned above )actually worked the trick was to hold vol up+down key (while the phone is off) and then insert the usb into your computer, secondly my computer kept of saying that qualcomms --digital signatures not verified and the port is supposed to be Qualcomm Lenovo HS-USB QDLoader 9008 where as mine showed up to 9091, to solve this I uninstalled the drivers and then disabled digital signatures (use goggle how to disable signatures verification on whichever windows you are using) and it worked fine. Thank you all

install cwm
Install cwm from pc and then try

Use HW flash tool
Even my Lenovo a6000 plus was bricked. But mine is more complicated than your's.
I've installed CWM recovery before. But unable to access it, atleast native Android recovery either.
"Rev-app" folder from "System" folder were deleted unfortunately. I couldn't even wipe, hard reset or anything.
After a long struggle, i've found a way out. I've came across a Qualcomm flash tool "HW OneKeyDownload Tool".
And finally, i won on it!
Download it from here: docs.google(.)com/uc?id=0B3qYFBKKL2hieDM1RUNMQWRsSHc
You need to have:
1. Mobile drivers installed
2. Universal ADB drivers (That ZIP will have it)
3. Stock ROM or any custom ROM
See this post on AndroidXDA for more info:

install cwwm
installing cwm from pc is the best way to unbrick

Dont feel bro.just follow the steps which u tried before to install cwm.but before that if ur pc cant find ur mobile.then use this command.
"Adb shell"
And it shows searching for device.

Recently I was tried to update mobile firmware (latest Kraft-A6000-S_S014_150730) by OTA update (via system settings->about phone->system update), that time my mobile was soft bricked like above you said. I downloaded firmware and installed then some time after got some options menu. And I attached that problem as picture.
Before that I rooted my mobile using KINGROOT apk v4.0 , there after I did unroot again using in the same app.
I thought unrooted mobile does not affect by system update (any firmware or OTA update by LENOVO). But unfortunately my mobile got problem.
I didn't took any backup before that. I don't know anything about CWM backup and all. I know only the root and unroot using KINGROOT app.
I need to recover my mobile back or tell me how to install LENOVO A6000 PLUS stock ROM or any other way is there tell me to solve the problem. Please guide me step by step process or any video link there it was little better to understand for me.
Please help me, it will be appreciated. Thanks.

Attach the device to PC through USB cable and Install the CWM through ADB .
Install the Stock Kernel through Update Zip option within the CWM.
That will freshly installs the Android OS.

You should try flashing the same scatter file with another flash tool. I too was unsuccessful, with exactly the same symptoms. I searched the web and I did find a way, that too didn't work, so I tried the flash tool of that website with the firmware available at XDA. It worked. I can't put links here, so maybe I can mail it to you. *Make sure you hit the reset button before flashing and backup your NVRAM folder. You really don't want to lose your IMEI like I did.*

I fixed it and flashed CM11 ROM

OnePlus2-No OS Installed-Marshall London Device

Hello people,
I did so many wrong decisions and I regret them all :/
Im gonna tell you all th details.
I got OnePlus2 phone and I rooted it.Then the GooglePlay didnt work and I tried to fix it with no success.
So today I decided to unroot my phone with a factory reset.With TWRP installed I deleted all memory from the phone.
I tryed to reboot it and a msg poped up saying "No os installed".
I looked up for ways to fix it with no success.I tryed to connect the device to my pc Windows10 and in device manger its shows up no problem just in the category "Marshall London Device" name "Google Nexus ADB Interface".
I think I bricked my phone.
How to fix my phone and get it back to the normal ?
thanks for the helpers
