Yes, do a factory reset then install rom and follow Aroma install steps that'll walk you through each section.

Edit: Installation Guide is in the download area for your model.
[Samsung Galaxy Note 20 Ultra ROMs, Kernels, Recove] farou2:
Thanks for your reply.. Just saw the installation guide it mentions that after flashing twrp I should flash Bootloader and Modem via Odin. Do I flash it by also using the AP tab in Odin?
[Samsung Galaxy Note 20 Ultra ROMs, Kernels, Recove] dr.ketan:
Bootloader files itself have installation instructions inside

If you already have latest bl and modem installed, skip this step

There are no any pending request so may be I haven't received request. Have you received auto response? You should get it in cases of receipt of request. Anyway pm me detail of transaction,will check it

I clean installed R09 and everything is working great. But there two apps in the Play Store that will not update, Chrome and Android System Webview. When I try to update it says "Pending" and never updates. I have tried rebooting and Safe Mode but no luck. What to do?
[Samsung Galaxy Note 20 Ultra ROMs, Kernels, Recove] dr.ketan:
Just updated chrome and no issue

Make sure you haven't removed

com.google.android.trichromelibrary

This must get updated before chrome gets updated (normally this app auto updates when you update chrome just before chrome update starts downloading)
[Samsung Galaxy Note 20 Ultra ROMs, Kernels, Recove] Eagle 3:
It's missing. I have no idea how it got removed. What's the best way to get it installed?

Anyone with dirty flash ?

Any problem ?

Many thanks in advance
[Samsung Galaxy Note 20 Ultra ROMs, Kernels, Recove] mcgomfer:
Have dirty flashed, and so far no problems.
[Samsung Galaxy Note 20 Ultra ROMs, Kernels, Recove] enebro77:
cool .... guess you updated the BL and then installed the firm, right ?
[Samsung Galaxy Note 20 Ultra ROMs, Kernels, Recove] mcgomfer:
Yeah, first BL then rom, and as I said have han no issues or problems. Because it's kind os bothersome having to do clean install every time new version comes out, and have to install your apps again.
[Samsung Galaxy Note 20 Ultra ROMs, Kernels, Recove] enebro77:
Indeed. I have never understood the reason why a dirty flash is a source of problems.

Having a master like Dr. Ketan, I am sure dirty flashing his roms is not a problem at all.
[Samsung Galaxy Note 20 Ultra ROMs, Kernels, Recove] Timtown:
Up on R09 and running hot, straight and, normal. Many thanks, Dr.K.
[Samsung Galaxy Note 20 Ultra ROMs, Kernels, Recove] TangLy:
@dr.ketan do you have new Bootloader and Modem for N985F, I can see that you are using the May version of them (BL_N985FXXU2DUDA_CP_N985FXXU2DUDA), while there is a July update already (N985FXXU2DUF8_N985FOXM2DUF8).
[Samsung Galaxy Note 20 Ultra ROMs, Kernels, Recove] enebro77:
Dirty flashed R09.

So far, so perfect good :)

Just one question @dr.ketan ... after rebooting, I can see that all the modules I had removed previously (Facebook and all that useless stuff including a lot of Samsung) were not installed.

Do you detect a dirty flash is happening and so the installation of the removed modules is not done ?

Many thanks in advance

Did you find that apps removed previously wont be installed when dirty flashing ?

That was my case ...
[Samsung Galaxy Note 20 Ultra ROMs, Kernels, Recove] Darmxz:
Hi, first of all thanks for the help.

I always rooted my devices and put custom roms in them.

Till note 8 I do this, then I bought Huawei p30 pro and do nothing with it.

Now I have a Note 20 Ultra with Exynos.

I have a question (please don't kill me).

Is really worth it root and flash this rom?

I mean it's a high price device and I don't have a lot of money to change it, so I'm a little afraid to forgot the stock thing and get into this world again. So I want to know if it's really worth it at least on battery SOT and Camera.

And for the Last things, if I have N985F what rom version I have to flash? The Q or R09?

Thanks a lot and sorry for the question.

[Samsung Galaxy Note 20 Ultra ROMs, Kernels, Recove] Redeye Dog:
Got my n986B/DS. My carrier is AT&T prepaid and they locked my account, because I moved my sim card from my Note 9 9which was working great rooted with Dr. Ketan's ROM. I'm hesitant to root my NBote 20 now because the CSM said AT&T does not support this model. I can't change carriers because of distance to cell towers. Been there, done that. They said they do not support the n986B model but they do support the u model. Are there any tricks I can do to fool their servers so I can restore my service with AT&T. She asked my IMEI and said that model is not compatible. TIA
[Samsung Galaxy Note 20 Ultra ROMs, Kernels, Recove] Timtown:
Yeah. Don't buy that bullshite. I hated AT&T for a long, long time. Dumped them and went with Cingular wireless. AT&T bought them. Bastards. So, I was hot to buy a SGT 7", root it and use it like the rest of the civilized world, as both a voice AND data device.

AT&T said "no". Couldn't have both on SGT 7". So, I said I'll take voice (VOIP was sketch back then) and, I could live on wifi APs. Then I acquired my first Note. The Note 4. Now, all of a sudden, according to AT&T, I couldn't just have voice and/or data plan, I MUST have both. Price was $169 per line. Throttles on data after 3GB (price x3 for my family). I lieft store, crossed the boulevard and bought a T-Mobile (unlimited V/D/T (all 4G) SIM. for $50. At that time, we lived at the farthest outpost of the realm w/r/t cell service/towers.

T-Mobile allows you to use wifi for voice. Even on unlocked devices. Eight hours later, I converted from pre-paid and switched to monthly subscription. I've paid $212 ($50 per line [x4"} for unlimited services for the last eight years.

You need to unlock your device and/or return it an buy an unlocked (often labeled "International") N986 (Amazon). Phuck AT&T.

[Samsung Galaxy Note 20 Ultra ROMs, Kernels, Recove] dr.ketan:
No and never, it's very risky. Your device can hard brick.

Hi mate, have a question on this. Im running your rom (thank you very much) but still cannot reach these stats. My best sot was somewhere in the range of 5.8 hour. Are you using any kernel tweaks or something t allows you to get the battery working for so long? TIA
[Samsung Galaxy Note 20 Ultra ROMs, Kernels, Recove] dr.ketan:
No any kernel Tweaks (always prefer stock kernel only)

Additionally did

- removed bloatwares I don't required

- put all apps in deep sleep which I don't needs notification or working in background

- put all apps in sleep, those I don't need priority notification.

Thats it

hi any one help me with the telegram link
[Samsung Galaxy Note 20 Ultra ROMs, Kernels, Recove] Timtown:
Do it.

Label it: DONOTFLASH_STUPID_RISKY and then anybody who actually flashes it will, most likely, no longer be a bother in your threads. Just a thought.

Bring back the "brick", cull the herd.

(I'm effing kidding of course but, I did get a good giggle at the thought.)
[Samsung Galaxy Note 20 Ultra ROMs, Kernels, Recove] Timtown:
You can also use use TB (and probably other apps) to go in and disable services and apps you do not use (DEX, Facebook BS, duplicate apps and on and on. I use Pro to debloat and then I cut deeper with TB.

Another thing to consider, everyone's SOT varies. Professionals use display different than Gamers. Folks whom use device for Netflix et. al. are gonna get less SOT just like Uber/Lift drivers whom use GPS. People who go around all day shooting HD videos, etc.

[Samsung Galaxy Note 20 Ultra ROMs, Kernels, Recove] dr.ketan:
No idea, Indeed never heard this before. May be something on your device have Tweaks to enable demo mod could be issue. Try clean install and straightway test power saving mode to narrow down error.
[Samsung Galaxy Note 20 Ultra ROMs, Kernels, Recove] nyamekye:
just did that sir and im having that issue i wanted to humbly ask if i could get the download link r08 and try a clean install to see.i actually thought it could one of the downsides of having an unlocked bootloader or something

May be your bootloader already newer than one in download area. Skip it, if device doesn't boot,

Flash latest stock firmware - start from scratch and skip bootloader and modem installation
[Samsung Galaxy Note 20 Ultra ROMs, Kernels, Recove] Darmxz:
Ok, all is working good by now.

What i did:

When i was stuck in Odin Flashing BL, AP and CP i unplugged the device and idont boot... So i open Odin again, and in the same blue screen i make the same process to get into download mode, so Odin recognized my phone, then i desperately flash the TWRP AGAIN, so it boot in Recovery mode so i could Flash the DrKetan ROM (no the original firmware) from there.

Then i did the magisk stuff, and etc.

Now i dont know what BL and Modem i have...

BUT for now is all working fine for me.

Thanks a lot.
[Samsung Galaxy Note 20 Ultra ROMs, Kernels, Recove] enebro77:
Dear Sir,

Instead of doing so, I extracted boot.img from your zip and flash it in result of not being able to start the phone (SAMSUNG black screen and reboots, so on).

Now and since that, what is happening from time to time (I have clean installed your ROM a couple of times) is that this error screen appears.

View attachment 5400189

I wipe cache, dalvik and internal and then zip work properly again.

Does this have something to do with me installed the boot or I should just download again the .zip ?

Many, many thanks in advance
[Samsung Galaxy Note 20 Ultra ROMs, Kernels, Recove] dr.ketan:
Check zip MD5 and compare with given in download area. Once it matches, clean install it.

Yes I have formatted the device doc, As I mentioned when I extract the ro9.zip into my PC, there isn't md5 to flash it with odin.

That's why I had to flash the twrp with odin from a separate file.

It is possible to downgrade from Android 11 to 10?
[Samsung Galaxy Note 20 Ultra ROMs, Kernels, Recove] Timtown:
Have you tried a "super-clean" wipe (everybody will say it's redundant but, so be it) Factory; Advanced (everything but MicroSD) then, format data (type "yes"). If so...

Try reinstalling ROM dirty over existing release.

If it continues, it's probably an app. Insure GPS is up-to-date. Look for System UI issues.
