    I have updated software 1 night before i updated last security patch which came in on august 1st and it says that the current version is A520FXXSBCSH4/A520FOJVBCSF1/A520FXXSBCSG2 i was trying to find 7.0 Nougat version of some of these firmwares but the only versions i found were Oreo 8.0.When i had 7.0 Nougat installed was this firmware version " A520FXXSBCSH4/A520FOJVBCSF1/A520FXXSBCSG2" same like this or back then weredifferent these? i am asking because i am confused about which firmware i need for ODIN, if someone knows please link me.I hate oreo its draining my battery a lot faster.

    New OS versions come with a new kernel. It usually takes several days for everything to settle down. I would wait another few days before deciding about the battery life.

    I dont think i will get used to Oreo, i can no longer remove the "white things" around icons even if there is option to do so it just doesnt work, it used to work on Nougat.Also the battery is very important to me more than new functions.

    XDA forum looks very confusing, i will try searching on sammobile, just to be clear i have to search for every of these versions A520FXXSBCSH4/A520FOJVBCSF1/A520FXXSBCSG2 or just one of it? This is my first time that im gonna try downgrade a phone so im not very familiar with anything but im a fast learner so i believe i can do it.

    Restart into recovery and clear the cache, to see if that helps with the battery. (Not the data, only the cache!)

    Nougat is around QK7. SH4 is Oreo. SG2 is Oreo. (SF1 is the CSC - the localization for your language, country, etc.) You can find Nougat at http://www.droidthunder.com/update-g...bqk7-firmware/, but you'll have to do a factory reset, so be sure to back up EVERYTHING. (See Backing up an Android Device.)

    Or, as mustang said, you can try on XDA Forums. (Sammobile only has Oreo.)

    Start at https://forum.xda-developers.com/sam...17/development for XDA.

    [Samsung] How to flash Stock ROM via ODIN is full instructions for running Odin to flash a Samsung ROM.

    (If you're allowing the battery to drop to below 40% before charging it, you're killing the battery, so don't do that. Go from 40% to about 99% [if the charging chip goes bad the battery can overcharge and that will ruin it.])

    https://www.sammobile.com/samsung/ga.../SM-A520F/XSG/ i have found these.But as you can see my PDA and CSC only states that they are 8.0 Oreo version, but there are some others that are 7.0 should i for example use A520FXXU4BRE3 this one? it says its 7.0

    i would really like to know which Nougat version i exactly had before but i forgot.So it doesnt matter which country it says its from? for example you sent me the India one and here i found the UAE (united emirates) one which is the one my phone currently has on A520FXXSBCSH4 you said SH4 is oreo.So i guess my Nougat version was also United Emirates and i should look for its version?

    One more question, no matter which Nougat version i install they all work and are the same as was my previous? i mean no difference in speed, battery duration?
    09-19-2019 02:04 PM
  14. Decoy021's Avatar
    Also should i download Nougat version you sent me or some of these https://www.sammobile.com/samsung/ga.../SM-A520F/XSG/ that are 7.0 United Emirates version?

    381 is Serbia.

    The different country versions of the ROM determine things like the language it comes in, whether it's set to work right to left (Arabic) or left to right (Latin or Cyrillic), etc. The radios are all the same.

    But, if you flash Nougat and you don't root the phone, it's going to update to Oreo later anyway. So if you flash Nougat, root it, to prevent updating. (Flash Nougat first, then root. If you root Oreo, Nougat won't be rooted. It's the firmware that gets rooted.)

    I wouldn't give that advice to root, if they do something wrong or flash something different it can damage or brick the device. If something goes wrong and they don't know how to go back stock . Root is for more experience people that know what and how to do it and how to get out of trouble if something goes bad. That's my opinion.
    You are very experienced in root, IAM also .but most are not.
