[Q] No OS Installed Karbonn A9+ / Flare S100 - Karbonn A21

Good day , can anyone help me with my problem?
The first problem was my phone prompted, " Encryption Unsuccessful" and it says that I should factory reset so I did. When I install a new ROM, it was successful but whenever I try to reboot / Power off, It prompted , "No OS INSTALLED, Are you sure to Power OFF" its been a week but I can't find any solution. Hope you could help me. :crying: It's so depressing that I can't even fix my phone. I really need your advice guys. BTW, The TWRP is working and my phone reads my memory card.

there is no cwm or custom recovery or custom rom that could help me
pls help...i m a newbie
please provide the stock rom for iris 504q+
Mate,
Don't panic and do something which bricks your phone. Try to hard reset your phone after removing your external memory card, since during factory reset, all data will be erased, including internal memory and the phone will become brand new as it was in the box, when you bought it... try different key combinations for this, it's only a try..
Switch of your phone, and press volume up key and power key for 5 seconds, you will get an android screen with no command display.. keep pressing the power key, it enters recovery, from recovery, do wipe data\factory reset and then reboot your phone....
Hope this helps...

Only way is to flash the original ROM file of 4.1.2 and then upgrade it to 4.4.2, by downloading the update zip files from lava's website.

When you say you upgraded the firmware and nothing happened, what exactly did you do and what steps did you take?
Also, for hard reset did you try vol down + power then vol up + vol down?
Thanks thanks thanks

Hi Nikhil,
Can you try to get into recovery mode? You need to understand a few commands of ADB also. Don't worry. Your phone will be working again. Remove the battery for a few seconds and put it back. Don't start the phone. First hold the volume up button and then at the same time hold the volume down button. Keep pressed both the buttons and then press the ON button ( All three buttons at the same time ). After your device vibrates a little and sows the YU Logo, let go of all the buttons......you should get into the bootloader menu. Tell me if you can do that. Will explain the steps further after you reply.
Yes I can enter into the recovery mode, but when I try to enter into the bootloader it shows fastboot mode for a sec and then all black screen. I want to tell you that my phone is not rooted and neither i unlocked the bootloader nor installed twrp or cmw!! But still it is bricked without any reason. Is there any solution to recover my data??

Hi,
I am able to get my phone back.
I just downloaded the file from http://builds.cyngn.com/factory/tomato/cm-12.1-YOG4PAS3JM-tomato-signed.zip and copied to memory card.
Insert the memory card my phone and then booted into recovery mode.
From recovery mode, select Install/Update zip from sdcard. Andriod got updated.
after update, reboot the phone. It took almost 10mins to boot.
After reboot, I had all my data.
Hope you ll get ur data back.
Thanks

Hello..watching my switched off yureka for over 3 days now. Tried flashing cwm recovery finding nothing else to do. Till that time I hadn't tried switching the phone on while plugged in. Don't know if the cwm recovery thing worked or not, but from then on I am unable to reach the recovery (vol up+vol down+power).
But then suddenly in the plugged in state my phone comes alive and boots completely!!!:cyclops::victory:. And then I get to know that while charging, the gandu phone is completing its boot process. But after a few minutes its blacking out and starting its on and off routine again. (minutes varying from 1 to 45 , not sure depending on what, because now I am running hotspot and LTE on the phone to write this on the laptop..and yet it is awake for more than 45 minutes now got a vibe that if the screen is turned off the phone will not shut down. ) ... guys please help. how to make it work without the usb pushed at its back...?
Edited a day later: went to the service centre.. They simply said the battery needs to be replaced. Yes it is all good now. Relieved.

Hey Buddy , Same here I am also using RR N, and suddenly one fine morning it went into bootloop. I am stuck at YU logo. Can you confirm that it stucks at userdata erasing and formating data/factory as well ?
I did a lot of research and I think i found out solution. Now my phone is reseting once it starts I will confirm.:fingers-crossed::fingers-crossed::fingers-crossed::fingers-crossed:

yes it did stuck once or twice at the userdata erasing stage when I was putting up the new ROM but after some attempts,it never got stuck at any stage but even after successful installation, the problem existed...Now I have given my phone for repair and the store person said that there is some power issue in the board...its not an software isssue.
