unfortunately there are no custom ROMs for your phone
all you can do is to root remove/add your apps and make a nandroid backup
this will be your "custom rom" I understand your frustration
you can try to root it by SuperOneClick
activate USB debugging on phone before better read thread above

thanks i have done rooting but how can i install a custom recovery for it..?
pls tell sir ... rply fast

did you use SuperOneClick or other tool to root?
believe me there is no CWM or custom ROM for your phone
I understand your frustration I was the same situation a few months ago when I buyed an Alcatel phone similar with yours in specs..but no custom ROM there..what to do ..so I made a custom ROM here
but believe me this is not easy at all because ZTE/ Alcatel are not well-known so no tools to prepare custom ROMs for these phones !
I will tell you the most important thing
never flash ROMs not made for your phone because these ROMs have a kernel that can affect/destroy your phone !

that means sir i cant install any recovery so i can went to recovery .... pls tell if there is if only if one recovery for my model is there... ?? pls tell pls tell sir..

but you should have a recovery mode on your phone shutdown phone then press power +vol down and wait even 1 min if nothing on screen touch it or press a button (if this is not working remove battery put it back and start again but with power button+ volume up )
this is recovery mode but not CWM recovery and I think you do not need CWM because this is used to flash custom ROMs so what to do with CWM if you do not have a custom ROM to flash it by CWM ?
I do not want to tell you how to flash a CMW by fastboot because you will make a mistake and flash a CWM that is not made for your phone ...
believe me CWM is not useful you don't have a custom ROM to flash it by CWM and I do not know one !

sir i have tried both the method for going into recovery but in the first method of pressing vol down+ power button makes my phone stick on boot logo but does not go into recovery mode...... and the next method when i press vol up+ power button i start getting vibrated continuesly until battery is taken out so sir pls tell me any method of installing recovery as i want to reflash its stock rom sir pls tell fast sir pls..
Thank You

Sir and pls tell me about the method of "how to flash a CMW by fastboot"
and sir i promise i will not flash a cwm i just want to reinstall its stock rom so sir pls tell or rply me fast pls sir its very urgent..

you have menu/volup/voldown/power buttons check some combinations to enter fastboot when in fastboot mode your screen is blank/black no logo there... only sensors buttons are active!
i.e.
Turn off the phone. Then press Power shortly. Then press and hold Vol down Menu and Power . This should enter fastboot mode. Then connect your phone to computer and follow the rest of instructions.
I can't tell you more because I do not have this phone ...
when entering fastboot mode connect phone to pc and open cmd.exe in adb.exe folder usually \android-sdk\platform-tools\ also do not foreget to copy in this folder your recovery.img
then enter from cmd.exe console this command
Code:
fastboot flash recovery recovery.img
done.. you have recovery installed find a key-combination to enter recovery now you can flash but where is recovery and stock rom ?
maybe you have a sync/update software to check for an update from manufacturer site ?!
maybe you have an installation cd or user guide ? check it!
to open cmd.exe start/run/cmd.exe also to open cmd.exe in adb folder easy way is to use Total Commander and navigate in adb folder then in Commands menu you have an option Open command prompt window
for adb.exe ...you need to install Android SDK
PS do not tell me sir you are a polite man..
a good day to you Sir !
do not make the mistake to flash a rom or recovery not made for your phone !

Ok I will not say you sir but can i say you my friend..?
My Friend Its a very complicated method of installing recovery to my phone I also want if there is any easy method and if i can install cwm through rom manager..

you really want to do something with your phone but unfortunately none is good for your phone do not try !
to have CWM recovery you need sources for your phone to compile them
also a custom ROM can be made only by a person to have this phone because every feature/change needs to be checked on phone without a phone is very hard to do something
when you buy a phone be carefully read about available resources for it !
but I think Froyo is not bad at all !
also check some combinations to enter recovery usually phones come with a default recovery but you have to find how to enter it !
also you should post your question here

For Karbonn A1 to go to recovery mode PRESS POWER BUTTON + HOME BUTTON AFTER THAT U WILL SEE ANDROID LOGO WITH CROSS MARK ON THAT TIME PRESS CALL BUTTON. U WILL ENTER TO RECOVERY MODE.

When I switched off the phone and press ome button + power button my phone hangs on karbonn logo screen does any body having some solutions for this pls reply me fast urgent..
Thank You

FastBoot Problem

Hello , I have arc s and i practically flashed all the custom rom successfully without fail . recently i had to re install my windows (7) and install flashtool again. Then the problem happened. I installed flashtool version 0.9.15.0 and also driver from its folder. When i flashed via flashmode using official ftf file ...its working fine . Also everytime i install something(Kernel) in fastboot , it flashes .Now i go to cwm and install custom rom(zip) with full wipe .what i get after is infinite bootloop. i never get pass the kernel image. not even bootanimation shows up.I tried everything and its frustrating that i can't install custom Rom now. Any help from pros would be really appreciated. Thanks

Are you flashing the correct kernel? Or are you hotbooting the kernel by mistake?
Sent from my MT11i using Tapatalk 2

Thanks for reply , i was flashing correctly . so far i've tried Iridescent_Zed_III (ics-lupus) , Xperia UltraKat v2.0.1(KK-provided kernel) but no luck . But i tried TouchwizRom 1.4v with superfusion kernel. it worked great. i don't know whats the problem.

Pardon Me.. But I'm a newbie... Custom ROM suggestions required...

Hi ,
I am new here.. not new to rooting ....
I used to use my Samsung galaxy grand i9082 but switched to nexus 5 last year...
Since then my grand has been sitting in my cupboard drawer. I also found this phone very slow performance so switched...
But now i am thinking of flashing a custon Rom to increase its performance and remove all the bloatware...
so i need suggestions of a stable custom ROM with good performance and all features working like dual sim ...etc..
Can you guys help me .... ?
Lollipop or Kitkat or Marshmellow expected with fast perfomance and no lagging ( I guess Marshmellow will lag too much so i can go with KK or Lollipop...)
Please suggest me ...

CM12.1

I cant even flash my recovery...( i dont know why.... its so easy for nexus 5 )
First of all i cant find any download link for CWM recovery for i9082...( .tar file which can be flashed using odin.. ihave the zip file with name CWM_6.0.5.0_Non_Touch_xenon92.zip )
As of now i have downloaded TWRP recovery i9082_TWRP_skullface.tar which is flashed successfully using odin3 v3.07.
but when i restart the device after booting into android it again shows android recovery ...
I also tried the unchecking the auto reboot in odin and removing battery after flashing and trying to boot into recovery but again no result ..everytime the samsung logo comes and again phone restarts and same goes again and again till i boot into the android.
Can anyone give me the CWM recovery...thanks in advance....
Also i have download 2 super user SU files with diffrent version.... UPDATE-SuperSU-v1.25_2.zip and UPDATE-SuperSU-v2.46.zip ...can anyone confirm if the latter one ( new version ) will work.....

Try this rom: http://forum.xda-developers.com/showthread.php?t=3073108
That is a CM 12.1 port to grand duos by pawitp. It is pretty stable and functional. Though I experienced frequent freezing with the latest build 20151115, I got it fixed by installing frost kernel ( here: http://forum.xda-developers.com/showthread.php?t=2927449).
After installing frost kernel, adjust your cpu governor to lulzactive, and your i/o scheduler to sioplus (the most recommended setting for Grand duos with CM 12.1).
Though the consequences of using custom kernel with that rom is that you can no longer uses delta upgrade features of that rom, you have to download full update build and flash it as if you're to flash new rom (though without wiping cache partition and dalvik cache).
Good luck with your quest to find perfect rom for your grand duos!

Install CM12.1 (Based on Lollipop 5.1.1) by pawitp. It is stable and very fast. I'm using it currently

i cant install custom recovery and root my p8000

hi everyone . i can't root my P8000 in noway and can't install any custom recovery
1.install supersu and when open it say "there is no SU binary installed, and supersu cannot install it . this is a problem'' then i turn on OEM unlocking and try it again but i face with same error
2.i decide to flash a recovery and install zip supersu file from that but i faild again because another unslovely problem , i open sp falshtool, load scatter file , click on download bottum , turn off the phone , when i connect usb cable , the device does not appear in the device manager interface '' a sound plays to say it is connected and then another sound to say it has disconnected plays straight away and I can do nothing '' i manually install mediatek drivers & preloader but still not working
can anyone help me please? thank you (im on stuck rom 20151203 )

I could only root by flashing philz touch recovery and the supersu-2.46 zip on the 12/03 build.
It does sound like a driver issue to me. Are you using windows 10? If so there is a great guide by skeleton1911 on how to install them properly.

Did you still see the screen "Your Bootloader Is Unlocked" thing whenevr you boot your phone? If it is, then good chance that your phone is still unlocked. Flash a custom ROM with permissiver zip file (found on Telegram groups) or a permissive custom ROM.
However, your phone might be forever "permissive".

Take it to the service center or phone repair technician. Besides short circuiting the test pins (which I don't have idea how, other users might have idea), nothing that you can do with it, I guess.
