Hello,
Can you tell us the make and model of your device?
Also can you elaborate what are you trying to do?
-Vatsal

My phone model is samsung galaxy y plus -gt s5303
Android 4.0.4
I am a noob just learning about android rooting
I rooted my device with bin4ry root .
And i was trying to install custom rom such as slimrom .i tried using rom manager but cannot run clockworkmod recovery as my phone model was not listed in support devices by rom manager.
If i tried unzipping rom file in basic recovery mode it says "E: signature verification error"
My question is how unsupported phone models can boot in clockworkmod or twrp recory .and if there are custom roms available for unlisted phone models in custom rom websites
Sorry for my english ,technical terms i used.
Thanks for listenning

[Completed] [Q] Cannot Flash SGH-T999

Hey Guys need you HELP.
I have a Samsung Galaxy S3 T999 which was running on android 4.3 (official rom). I rooted the device and also flashed ClockworkMod Recovery which was successfull.
I tried few roms and it did not work and i got an error which siad I have a d2spr device and the rom i was trying to install was meant for d2tmo.
now how is that possible? d2spr is for Sprint and d2tmo is for T-Mobile... and my device is T999 (T Mobile) (I REALIZED THIS AFTER MESSING UP MY DEVICE)
Later I flashed it with a custom rom via recovery menu and after that i tried loading GAPPS also from recovery mode. The custom rom was ok but gapps failed to install.
After falshing the custom rom i checked about device and it says the model number was dat of a sprint mobile (i747)
I tried other custom roms and gapps.zip but now my phone will not boot...when i turn it on it shows the SGS3 CWM screen and reboots into recovery.
No luck trying to flash it with a stock rom using odin either.
NEED SERIOUS HELP PLEASE!
Hi, thank you for using XDA Assist. First, only flash roms that are specific for your exact device. With your model number changing like it is it appears you've flashed some roms for other devices. You may not be able to recover the device. but see this, http://forum.xda-developers.com/showthread.php?t=1949687
