The only thing I did different this time , was to previously uninstall Rom Tool and Tweaks Pro ( just for precaution) , then rebooted without those apps before going to newest TWRP and flashing Q10.
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] dr.ketan:
This is a good step, though people here hardly read instructions carefully, since last few version if someone instll dirty flash ROM, ROM tool will consider as new install and ask to reapply essential fix, which is must after ROM update.

Same goes to Tweaks Pro, It has ability to detect ROM updation and offers to re activate when first time you open after new installation of ROM.
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] Мишкa:
Sorry, I never ever did update a ROM, can someone tell me how to go from Q9 to Q10? I don't want to do anything wrong here ! :o

Greetings and thanks in advance,

Мишка

Edit : nm, just found the guide 2 pages before.

Last question : what is meant by "just a simple factory reset" - "wipe dalvik/cache"? Or what?
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] dr.ketan:
When you select wipe option on twrp

There is a swipe option at bottom of the page, that deletes non Media files like apps, contacts and other data but keeps other file you stored on internal storage

This option is fine when you just updating my rom like Q09 to Q10 (Unless stated otherwise)

While another option is format data, which erase everything on Int storage too, that's usually not required when updating NY rom version (Unless states otherwise)
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] Мишкa:
Okay, thank you v much for your fast answer!

So this means I have to re-download / install all of my apps etc.? But it will keep pictures, videos and music?
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] dr.ketan:
Exactly. Though I strongly recommend to make backup of your important stuff, you nevertheless knowledge Android when it f*

Look for swift backup on play store to backup restore sms/apps etc
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] Мишкa:
Thanks m8!

Is Swift Backup better then Titanium Backup? Just curios which one to use. Swift got 50k downloads, Titanium 10M.

Edit : plus when I restore such a backup, will everything be exactly like before?
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] dr.ketan:
Titanium was amazing for long years but now not updating and fixing issue on newer os, it's been almost a year since issue (I believe it's long enough) and seems developer no more kin to fix.

Swift backup new but doing amazing. I was using titanium for almost decade and nightmare to give up but shifter to SB since more than 6 month and now trust it more than tb.

Thx for this New Rom dr.Ketan

Question .... during the installation in aroma, once the 3minit is selected ... when the ROM flash starts, in the log I read 3Minit not available ... is this correct? I have not even found Viper4Android as usual I only ask not to make mistakes Thanks
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] BasketCase7:
I have read very well installation guide, but for safety I would like to ask if there are any problems with TWRP if I install Q10 over TH7 stock roms?
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] dr.ketan:
If you read first para, you will find that I have also flashed stock th7 before Q10, so shouldn't cause issue. But read installation pdf available in download area
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] dr.ketan:
Any N976 user have flashed Q10?

Please report me how it goes. I have added support completely blindly and without having 2.5 one ui Base for your device. But expecting it should go fine at least after Appling essential fix
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] dr.ketan:
It's normal. As stated in changelog, some mods won't available.
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] BasketCase7:
Yes, I read..but using google translation I was looking for confirmation to be sure, thank you very much
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] Мишкa:
Backed it up via SB. Instantly bought the premium, buttery smooth.

So if I do install Q10 now and restore my apps, messages and call log, everything will be like now in Q9 without any problems? :))

1 year of being a heavy user of my note 10+ and i love it, but since day one, i saw how bad the battery management was with the exynos version.

[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] sevsman:
Ketan does love to tell people to read the changelog and complains when they don't, but what about when the changelog is wrong?

It clearly states that 3minit is available in this release lol

After appling essential fix

My device N976N

Have a bug

The sim card mode has swithched from Single SIM to Dual SIM. To apply this setting, the device will be reset to its factory default setting and will restart
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] dr.ketan:
1.Can you point me where I have written 3minit is available in this release so I can edit it.

If you saying about ROM features then, I have made clear in change log about missing some mods. Here screenshot.

2.As you said earlier today, people read latest chat then also my answer available in latest chat.

3.Also when someone select in aroma, during installation it notify users that this mod is currenly not available, so they need not to worry it.
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] dr.ketan:
I am aware about it, looking into it in half an hr.

It states that some other options that are available in the RC may not work but doesn't say anything about the options mentioned not working.

[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] JAsolar.Vn:
Ok Dr !
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] sevsman:
But you then mention further in the changelog that the 3minit is available and other mods may not be. It's entirely contradictive and lacking the correct information in the right places.

Maybe I'm just pedantic as I'm a native English speaker but I'm not the only person that reads it like this.

Since this is not the final 2.5 release I guess I'll just w8 till you release the full 2.5 UI. Or won't you do that any time soon? Not asking for ETA or anything Dr.
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] dr.ketan:
Unless there is major bug, I won't re release ROM for same base. Only reported issue is selfie camera on thrd party app, but that has nothing to do with ROM, it should get fixed as soon we have new TWRP & Kernel based on OneUI 2.5 source
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] dr.ketan:

[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] dr.ketan:
Tweaks Pro last version will work like before. Only there will be one change. There won't be "More Option" in power menu but same thing you will get when you long press Reboot Option.So it is there but now it is hidden. I will update this info soon on webpage.

If you have no issue with dirty flashing then it's fine. If issue arise,go clean.
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] Мишкa:
Quick question, I'm currently in the installation process - flash the N975 Kernel or skip the Kernel step? What is right?

edit: just asking, because Doc said kernel is the same as b4 anyway :o don't wanna mess this up ;o
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] dr.ketan:
May be misunderstanding here. This mode give 360 degree rotation. Normally device rotate only 270 degree while this mod enable 360. This doesn't have effect on any app landscaape/Portrait, If app doesn't support landscape, this mode will have no effect.

For stock launcher, Landscape mode is available natively. Long press home - home screen settings - Enable Rotate to Landscape mode

In case you want landscape on lockscreen, Tweals have option under General section. refer to Tweaks page for more info/email us. Here discussion related to Pro will be off topic.

Doesn't metter. It doesn't reqire when you flashing ROM if your device is N975, but still selecting it, doesn't harm. For N976 it is must.
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] marcjuh:
So why doesnt it work for me? When i flash rom in the end...during flashing it says...no 3minit available

Never mind....got the info i need and will wait for the update kernel and twrp

[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] Мишкa:
not sure how long it took last time - but after selecting kernel and one mod it says "Please Wait..." since almost 10 mins... :o

That is Note20 ultra lte

I have already released rom for N20 ultra 5G but yet haven't received report if working on N985 or not, you may ask on thread. I believe it should work, can't promise for separate support as already running shortage of time and difficult to add more.

[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] Flame Red:
In case anyone is thinking about backing out to Q9, I still had the old TWRP and Zip files sitting around.

I was a bit concerned as I had previously flashed the boot and modem for Q10 and we all know that often it will not let you go backwards.

I used ODIN to install the Q9 TWRP. It rebooted into the old TWRP. I then restored the last TWRP Q9 backup from within TWRP. But do not let it reboot after it is done restoring! I then immediately dirty flashed the original Q9 Zip again on top of the Q9 just restored. After it flashed, it rebooted back to Q9, no boot loop.

Back on Q9.
