Downgrading j7 software - Android Q&A, Help & Troubleshooting

Hello!
(I'm bit of a noob so I apologize for that)
So I wanted to downgrade my J7 because of the most recent android update my phones touch screen hasn't been working.
The phones screen got replaced once and before the update it worked perfectly fine.
My problem is that my phones binary number is 5 and none of the older versions of android on the J7 have a binary number of 5, only 3 and 4.
So is there a way to downgrade that too or do I have to do something else?
My J7 model: SM-J730F

Maybe Samsung lies again.
It's not first time...
Nevermind we have LineageOS 13 and if djeman(we) fix HW Composer djeman continue porting LineageOS 14.1 :victory:
Sometimes people who work there doesn't have knowledge and with all the different versions there it is not very clear which phone is mean't. I look at the latest firmware at sammobile weekly. And until now there is not a single version for F or FN with marshmallow. Since this is a low budget phone there priority lies on the expensive phones.
Hope never dies.
But I how there will be at some point official Lineage versions which are updated frequently.

Hey [email protected] there is mentioned J3 (2016). But there are so many different version: some run stock marshmallow some lollipop.
I don't know if update means one version higher( MM-> N, L-> MM) oder just every version to MM.
To many different phones named J3 (2016)...

MM runs only US Verizon version of J3 6 with Exynos soc
Our version on European territory running Lollipop and it has SpeadTrum soc.
That's difference than J3 6 with MM and J3 6 with LL
Maybe Samsung push MM update but that's maximum from Samsung and we don't know when we get it or did we get it...
Only Samsung S models get latest major OS updates but only 2 on eg. S6 won't get Android O.
MM TW ROM is great but nothing better than AOSP Android :victory:
J3 6 is low budget phone so Samsung doesn't carry about them, important are S models because they cost 3X more that J3 6.
For now latest patch for J3 is 1 may 2017. we can wait for Samsung and he's TW MM ROM for J3 6, but I think that we get Nougat ROM for J3 6 before than Samsung Upgrade
J3 prime is only $50 and runs Nougat. Buy it off amazon if your to lazy to wait for Nougat on a J3

Hi, I contacted Samsung several times that confirmed me the update to android 6. Yet my research on the internet seem to contradict that. So what is it really like?

Samsung Galaxy A7 - AF00FD -showing signal with no sim

Hi All,
I just flashed a new rom to Galaxy A7 model A700FD because of bootloop issue after uninstalling SuperSU, the previous android version was still kitkat 4.4, and updated it to 5.0.2 lollipop version now.
I haven't tested yet if everything is working, but it makes me wonder why it is showing carrier signal even though there is no SIM attached to it. Is this normal? or do I need to flash/modify anything?
I did factory reset and wipe partition after flashing the new ROM.
This is Galaxy A7 2016 version.

Flashing another Region's firmware on Samsung J7 Pro (SM-J730GM)

Hello All,
Please I want to know the consequences of flashing the rom of another region on your Samsung device. Let me explain why I ask this
So recently I upgraded my Samsung j7 Pro (J730GM) to Android 8.1 Oreo and that update changed the binary version of my device to 5 (i.e. J730GMDXU5) so I tried downgrading the phone back to 7.0 but that did not work because Samsung has not released an Android 7.0 Nougat firmware with binary version 5 so downgrading the normal way was quite impossible.
Now I recently found out that Samsung has released an Android 7.0 Nougat firmware with binary version 5 but the region/country it was released for is Mexico while my phone's region is Thailand.
Now my question is, is it possible to downgrade my J7 Pro with the Mexico firmware although my device's region is Thailand because they are both binary version 5? If yes, what are the possible consequences?

TWRP custom bootloader on Galaxy M30

So i have had me galaxy M30 for a while now it came out with android 9.0(Pie) and just recently got the android 10 update to OneUI 2. I haven't rooted it or installed a custom boot loader yet. i wanted to do that and i was doing some research and I read about how TWRP isnt ready for phones that come with android 10 out of the box. i was wondering if the would have a problem on my M30 too or if its safe.
if it is safe to install TWRP in my M30 the has already been updated to android 10. Then where can i get the suitable version of twrp and the steps to install it. Also where can i get the stock boot loader incase I wanted to change it back.
device info:
Galaxy M30 SM-M305F
android 10 (OneUI 2)
Exynos 7904
security update version M305FDDU3CSL5
Thanks

Need help regarding One UI 2.0 on A10

I have a Samsung Galaxy J7 with non-original screen and after updating it to android Pie it's touchscreen stopped working, after going through a complicated process i managed to downgrade it. I have another device; Samsung A10 with non original screen. As android 10 is already available on A10, i'm afraid to upgrade it because of my past experience. Anyone hear who is using fake/non-original screen and have upgraded to pie?

You can upgrade it to Android 10.
In case, your touchscreen doesn't work, you can downgrade to android 9 on A10 via odin mode.

For A10, android 10 and android 9 use the same binary version, which is version 3.
Therefore, you can downgrade to the latest release of android 9.
The binary version can be obtained from the bootloader's filename found in stock firmware.
The bootloader's filename general format is as follows: BL_A105XXXU3XXXX
U3 is the binary version.
You can compare before you try to flash
