ROM Manager sometimes doesn't like the CWM version you have on your phone. Do a nandroid backup by booting your phone into recovery, select backup and restore>backup.
I'm afraid I don't know the button combo to get into recovery for your phone but I'm sure a search of the relevant thread will tell you.
I try that also, in recovery mode, but the term backup of restore didn't show up.
only boot, foto install and update from zip file, wipe chache

I also have the same issue. I gave to Samsung service and they also returned saying Motherboard has to be replaced for Rs 7000. I have the i589 PDA files for ODIN and tried reflashing in Download mode, but flash not progressing and ending as Failure.
Can anyone please advise?
Rajesh
When flashing make sure to wipe everything!
Do it as follow
Wipe Data, Factory Reset
Wipe All Data – Preflash
Wipe Cache
Wipe Davik Cache
Then just reboot.

I Went to the service center and they just simply reinstalled the stock rom and charged Rs.200 only.
I am still not able to find working indian firmware.
Not much mods or anything available for this device.

I tried that but no success.
Also there is a temp. CWM available which neither makes a perfect nandroid backup nor wipes dalvik cache.no response on chosing wipe dalvik cache.

[Completed] Boot loop after messing up EFS folder.

Hello. I think I messed up the EFS folder on my Samsung J3 Pro (J3110) phone. I have a backup of the EFS folder though but I could not restore it as it's just the folder and not in tar or img format. My phone is in boot loop no matter what I do like flashing the stock rom a few times and try to wipe data and cache in the recovery.

Greetings and welcome to assist. A corrupt efs folder would not normally cause the phone to bootloop it would only cause you to lose baseband. How did you back up your efs ? If it was twrp then restore it with that. I would try flashing a stock rom first though to see if it fixes your bootloop
Good Luck

Hi, thanks for your suggesstion. I tried flashing the stock rom but it's still in bootloop. I even wiped the data and cache in stock recovery and the phone reboots at the spinning Samsung animation. And yes I have the EFS folder backup but I cannot restore it as my phone is in the infinite bootloop state now.
