Now running on Android 6, but i want downgrade to Andoid 5. Through One does not turn out, error during setting of recovery.

You need to wipe your data partition and flash the stock firmware
As I know, you can't downgrade your Tab S2...If this isn't right, please correct me.
PS: Hope my english is not to bad...

I don't know who exactly said this, but I remember that it was impossible for me and many others to downgrade from 5.1.1 to 5.0. Why should it be different this time?

It's not impossible. It depends on the firmware. If the firmware has had a revision update then there are occasions where the bootloader will not allow the downgrade.
However usually Samsung will inform the user of this before the OTA is applied.
A firmware revision will usually have U2 in the build number.

Did you mean, a firmware with an U2 in the build number can't be downgraded? All the firmwares I used in the past and for now have U2 in the build number...
My English is really not as good, so I didn't understand everything you wrote.
I'm sorry if I told something wrong.
Indeed, when it contains U1 in its firmware-name, you better not flash those if you're already on U2.
In the list that you can find here:
http://www.sammobile.com/firmwares/database/SM-T810/
the oldest 9 firmwares (bottom of the list) are all U1 firmwares, you better not use those.
All the other (more recent) firmwares are U2 versions, so you can flash all those if you want (doesn't matter if it's 5.0.2, 5.1.1 or 6.0.1.) if you have the SM-T810 model of the tab S2 of course.
Hello.
I am new to everything related to Huawei and I have a small doubt please.
I have a Huawei P9 Lite 2017 PRA-LX1 (exactly the same phone and specs as P8 Lite 2017; just a different name used by Huawei for marketing and regional purposes).
I have recently updated the build number through the inbuilt Huawei system update to version B162.
Please note that this was only a 400MB update with very minor changes and it was not a full ROM installation. Please see attached screenshot.
I am going to unlock the bootloader, TWRP and root very soon. I read that on the forum that sometimes people have to flash the original version of the build number when their phone gets soft or hard bricked in order to recover their phone.
I wanted to download the original build number as safety in case something goes wrong.
I can't remember the build number I had previously to B162.
1. How would I find the original build number I was on when I bought the phone? Only through a factory reset?
2. Is it really necessary the original build number to recover my phone (if needed one day) or another build would work?
Sorry but I find this Huawei updating method rather complicated or confusing.
Thanks in advance for any advice.
Factory reset don't work because it will same build that you on now. Perhaps if you install firmware finder you can see previous builds

Thank you for the answer.
I do have Firmware Finder installed but as I mentioned I did not memorise the previous build number so I would not know which one to look for.
I suppose that if I search for build number B162 (my current updated version) it would work in case I need to flash the original version if any problems arise.
Correct me if I am wrong.
Also in relation to my question #2 any idea please?
Thank you so much.

I have honor 4x(different phone, but this part of the phones might be same).
I think FULL firmwares from firmware finder can be flashed in TWRP and in that case you'll only need to worry about getting the firmware which has the same specs as your phone.
TWRP dosen't do any version checking so you don't need to find exactly correct version.
I don't know will this work, but if you get stuck it's good to know.

Yes it is good to know I will be able to flash any version as long as it is for PRA-LX1.
With some other phone brands I had in the past downgrading was out of the question (LG G3 and G4 for example).
Not sure about Huawei in relation to downgrading.
My opinion is that this should be all standardised all across Android anyway and not all different between phone manufacturers.
Thanks for your reply.
basically the only thing you need to look at is C432 in the firmware number

You MAY find your original build number according to your region:
https://mobiletech360.co/huawei-p8-lite-2017-stock-firmwarerom-android-7-nougat-pra-lx1/
But even if you do i doubt that you can revert it back, I had a PRA-LX1C464 which is the region code for Turkey, I wanted to update it through Firmware Finder and successfully did. But it changed my phone' build number to PRA-LX1C432, and I can't revert it back to C464. My phone is single SIM, but the firmware I'm using is dual SIM (wtf huawei? ) . So far so good though, phone works fine.

You need to rebrand your phone aka flash another oeminfo that is related to your device. This will lock your bootloader, so make sure you are on stock EMUI first, flash the new oeminfo (make sure it belongs to your device), go to erecovery and restore your device, this will wipe all your data and download the firmware of the oeminfo you flashed. You can unlock your bootloader afterwards.
I attempted to unroot my note 9 with odin and ended up flashing what i thought was the correct software. Now my phone is asking for a puk sim unlock code. Anyway to fix this?

you will have to find the exact model of phone including what carrier it is from.
it will give you an idea of what exact firmware file you need.
It was a sm-N960f/DS from ebay seller never-msrp. It came unlocked and everything when i bought it

well ure device is international so there's no real official firmware for TMO .
use samfirm tool v0.3.6 to dl another firmware:
enter model as followed: SM-N960F
Enter CSC as followed: DBT
tick the auto box.
then check update and download.
it should be the best firmware even if it dosent match USA carriers.
if it fails check logs because your windows might need a specific redist. version. it will tell you in the logs if ure missing a components.
remove sim and reflash everything.( fill ALL 4 slots in odin with corresponding .md5. be sure to use csc.md5 i the CSC slot and not home_csc.md5)
after flashing let it boot to initial setup. shutdown device and insert sim and boot back up. if u still have an issue. flash twrp again use ketans guide and use method 1to flash his oem unlock fix root v5. dont skip any steps from his guide.
report back here i might have a file CSC file for you to flash.
Ill attempt it and update you on the result

Why did you not just remove your Sim - Card and do a Factory Reset?
Even with Knox Tripped, it should have just reinstalled it original firmware which would have un-rooted the phone.. :angel:

Hello everyone i've been really struggling with updating my phone that i got pre-owned It's a Samsung Galaxy Note 9 (SM-N960U) and I have not recieved updates since I got it the phone is still on Android version 8.1.0 and security patch from 2018 so i've been really wanting to update it to the latest version but I couldn't and i figured out that phones from AT&T only update via their own app or OTA thing anyway I thought of flashing it with a stock firmware VIA ODIN but i checked on sammobile that the note 9 AT&T csc only has 1 update and thats 8.1.0 also so i was wondering if i can use some other firmware to flash it or do i change csc? would that work if i changed the csc or am i gonna have baseband and signal issues? I tried KIES it said it didnt recognize my phone probably because the software version has never been updated and very old , i wanted to flash it to a different CSC than AT&T but i dont think thats a good idea, please help

Kies is for older Samsung devices, Smart Switch is for newer Samsung devices.
Here is a list of firmware at Sammobile that has android 10 for your device. They are for T-mobile but I'm pretty sure it can be used on the AT&T Note 9.
https://www.sammobile.com/samsung/galaxy-note9/firmware/sm-n960u/tmb/
Here is a thread for AT&T note 9 where another user flashed their Note 9 with firmware from another carrier. Use the T-Mobile firmware and follow the steps from post #4 of the thread linked below.

No, the bootloader does not need to be unlocked before flashing if you are flashing stock software, unlocked bootloader is required to flash custom software, not stock software. There are some manufacturers that require unlocking bootloader even when flashing stock software but Samsung is not and probably never will be one of them.
You can flash your device with stock firmware any time you want, provided that the firmware is not a firmware that is older than your currently installed firmware and if the firmware is for your model number or an equivalent variant of your device with a similar model number and the same CPU series.

You can boot into download mode and it should say whether the firmware is "official" or "custom".
As I said, you can flash stock firmware provided that the firmware that you are flashing is not older than your current firmware, you can't downgrade the firmware, you can only flash an equivalent firmware to what is already on the device or a newer, updated firmware. Your error may be due to this. For all Samsung firmware, the 5th character from the right in the build number is referred to as the binary version. Your currently installed firmware has a "3" for the binary version, this means you can only flash a firmware that also has a binary 3 or you can flash a firmware that has a number higher than 3 but you can not flash a firmware that has a binary that is lower than 3(you can not flash a binary 1 or 2 firmware).
Depending on the specific error that you got, this could be your issue. What was the specific error that you got?

When using Odin, in the box that shows the flashing process, it should say exactly which error you are getting. When I asked what error you are getting, I was not asking "why" you are getting the error, I'm asking what it says in that box. Post the exact name of the error. Try to flash the device, while it is flashing, watch the dialog box in Odin, when it gives the error, take note of exactly what the error is, you can scroll up and down within the box and read all of the output data in that field.
Yes, it could be due to being from a different region but I doubt it. It could also be because your device is a Snapdragon version but the firmware that you are trying to flash could be for a Exynos version instead, or vice versa.

You still aren't telling me the SPECIFIC error that you are getting in the dialog box in Odin. That has been the most important question to understand your issue but you keep dodging it. Flash the firmware, watch for the error, take note of exactly what error it says it is, then post exactly what it says the error is. If you can't post that then there is no point in replying.
If you are trying to flash the device in a different region, you may not need to flash the whole firmware from the different region, you may be able to flash just the modem.img from the alternative firmware. To do this, extract the firmware, find the modem.img then convert that modem.img into an Odin flashable .tar using 7zip with its highest level of compression, then flash the modem.img.tar via Odin.

Strange, your screenshot doesn't show an error, it just stops without giving an error.
I'm assuming that your firmware came in multiple parts with some CSC files? If so, try flashing without using the CSC files.

you can downgrade by 2 or 3 updates only on the F variant. you can only flash firmware that shares the same bootloader version number that you have now.

any guide for using Odin to flash firmware will be fine. you need to know your build number or baseband number. it'll be your model followed by some letters and numbers.
the 5th character from the end of the build number is the bootloader version number.
my build number is G781BXXU4FVI4
so my current BL version number is 4, any firmware for your phone that matches your current BL version can still be flashed.
Sammobile is about the easiest place to download older firmware but it's SLOW!!!!

any guide for using Odin to flash firmware will be fine. you need to know your build number or baseband number. it'll be your model followed by some letters and numbers.
the 5th character from the end of the build number is the bootloader version number.
my build number is G781BXXU4FVI4
so my current BL version number is 4, any firmware for your phone that matches your current BL version can still be flashed.

yep that's it. make sure you definitely get the correct model number and also the correct CSC CODE too.
check settings / about phone / software info / service provider software version / check for 3 letters appearing 3 times here, that 3 lettered code is your csc code and you should download firmware that matches yours (although it's not earth shatteringly critical).
google for Sammobile and put in your model number and csc, you'll see what firmwares are available.
