Hi, I apologise for the new thread if this is covered elsewhere....I have tried to search for this specific issue but can't find it anywhere.
I accepted an OTA update to Lollipop recently (from O2) which I regretted shortly afterwards, as it resulted in inferior battery life, lock screen problems etc. I decided to return back to KitKat and searched for the method to do this. I downloaded the correct 4.4.2 firmware from SamMobile and followed their instructions using Odin v 3.10. The firmware appeared to flash ok (got the green PASS!) but I am now stuck on the Samsung boot screen when I switch on the phone. I've tried reflashing the same firmware again but end up with the same result.
I've tried a battery-out/recovery mode (volume up + home + power) but it won't go into the recovery screen and I end up locked in the Samsung boot screen again.
Can anyone offer any help or advice?
I was on stock ROM preparing to Upgrade to Lollipop
on first step I pressed power and UP for some time as explained in the upgrade process , and I went into bootloader mode
But cursor is circling and I can't choose Down to get out
I ve managed to download a new firmware with spFlashtool (W10) thanks to XDA forum
Got green Ok from Flashtool, but when rebooting the S3 :
nothing happens now on power on , but when I connect to PC it starts bootloader again with cursor looping
other attempts with stock rom with same result
I feel my phone is dead !
I was quite happy with it

Try a hard reset from buttons...probably ur sticker bexoz u downgraded
Samsung has warned already that it's not safe to downgrade after updating to 7.0. Since the bootloader gets upgraded it will cause problems. If you have good skill in software you can manage.

I've upgraded to 6.0.1 to 7.0 then downgrade again to 6.0.1 many times on my G935F without encountering any problems. I prefer MM with Xposed better than 7.0.
If phone doesn't boot after upgrade or downgrade, I just do factory reset/wipe data in Recovery.
But because the phone doesn't have a detachable battery, to go to Recovery you have to press Vol down + Power + Home first then when screen goes black you have to immediately press Vol up + Power + Home buttons to go to Recovery.

have you solve this issue? i'm facing the same problem...please help...
Downgrade is possible without repartioning? Any advanced member guide pls. If you are flashing files separately, you will need the pit file too to downgrade and if you are flashing with full rom image in single tar file containing pit file , then its ok , i think in major os change partition table changes , so any advanced member opinion about downgrading process is needed.
Hello,
I tried installing 3 ROMs onto my galaxy A3 and it keeps on bootlooping after the ROM is installed. It is SM-A300H (2015 model). What shall I do? It was on fully battery and was continuously bootlooping and not responding to power button so I left it overnight for the battery to get trained.After the battery was down I was able to boot it into bootloader mode and then installed a new ROM from sammobile but still it bootloops. What shall I do? I read that A3 is region locked so I selected the right ROM for the right country on sammobile but still it boot loops. I used Odin to upload the ROM. Please let me know what shall I do? How to get my phone back with 5.0.2 official samsung ROM and not make it bootloop.
Hey, I was running Lineage OS 14.1 and then decided to go back to Stock because of network & Bluetooth issues. I flahsed the right stock rom 5.1 , it booted right on, did an OTA but the phone didn't turn on after that.
I tried Vol down + Pwr to boot bootloader, i tried to connect charger, connect to my laptop but the phone is just not responding to anything.
never downgrade it hard bricks, you can't do anything i think unless you have a jtag unit, you did an OTA and apparently it hard bricks the phone if you weren't on stock the whole time
Unfortunately you can downgrade it without problems only with de-bloated roms flashed from twrp
