Needs to install on PC, then connect device with emergency recovery option
By the way there shouldn't be issue rebooting download mode, try this
Connect device to PC
Keep holding vol down + power - As soon as device screen turns off (reboot), release power and hold Vol up +down
This should reboot device to download mode
Remember you needs to connect to PC during this. Sometimes perfect timing is needed, keep trying and you should have download mode, once you have straightway flash stock rom and use Csc*.tar.md5 instead home_csc*
Dear Dr. Ketan,
Thanks a lot! I will try this tomorrow. Very much appreciate your support!
I see on the downloads page there is listed a "new zip" for full rom. I flashed before the new zip was listed. Do I need to reflash?
By the way the battery on this is amazing.

I you were "Test User" of T05 (Downloaded from another location) then yes, else it is same *_NEW.zip since it is public.
Another clue : If your ROM Tool - Mods & Misc Fix have option for App Cache Cleaner, you are already on New and no needs to flash again
I wasn't a tester and no App Cache option in rom tool>mods and misc
Thank you for your quick reply.

Thats only difference, if you are fine without that option you are fine with skipping update.
@dr.ketan check please something in your rom, the rom is smooth and very good but there is a bug with updating play system updates. I flashed the stock firmware with root to see if it was root related or rom related, and it is rom related because now I can obtain normal the play system update. I hope you are not offended I like your rom with all goodies but this one bug. I don't know if it is because of RW system now or I don't know. But with the stock firmware it is working normal.
I've seen 0 problems with play system updates on this rom, do you mean apps on the play store? What is play system?
Play system update is a security update not the security patch it's shown on the third place in software info. It must be February 2023 or March 2023.

No idea as not using Viper. Few pages ago someone posted github link to of Viper, check if you find any similar report there or may post issue to get fix

After digging ino it found there is a issue, I can fix it but at presently fix isn't good. Fixing it may be unacceptable to many users as it may brick some critical patch, while this bug hardly making any issue to majority of users. Unless I found perfect fix, I am no going to address it.

Data Encryption :
Since we now have TWRP with data encryption support, What you prefer to have ROM with Encrypted/Decrypted data?
Benefits :
Bugs :
I have added poll to OP, Kindly vote, If there are enough users to test Encrypted then I may make Two version of ROM for T06.
T07 will have data Encrypted/Decrypted depend on what majority of users choose.
Since we now have TWRP with data encryption support, What you prefer to have ROM with Encrypted/Decrypted data?
Benefits :
- With data encryption your data will remain safe
- Won't require to Format data while moving between Stock/Custom ROM (Encrypted data supported)
Bugs :
- TWRP have still one bug, If you set LockScreen Password, TWRP can't decrypt it. So you have to disable Password in case you want to use TWRP with Internal Storage Access
- May be Encrypted related any bug, We needs to test more but Primarily seems no any issue
I have added poll to OP, Kindly vote, If there are enough users to test Encrypted then I may make Two version of ROM for T06.

So I guess the password drawback will be just when using TWRP, right? Not that you can't use fingerprint or other screenlock passwords at all when using your phone ... Then it wouldn't be much a problem or difficulty to just disable it when using TWRP related tasks.

Yes only while using TWRP. If you set lockscreen password, twrp won't see your internal storage that's only drawback. Same time it protect from stealing data from twrp.
For normal use while phone booted to android, no limitation using password/pin/Finger print/face lock
But one has to wipe data to install this type of ROM, right? No dirty flash possible?

One time while moving from decrypted to encrypted.
Dirty possible from encrypted to encrypted. Indeed from stock rooted to encrypted custom dirty flashing possible

IMEI BAckup only possible after you root device.
Once you have rooted device, you should make backup and keep it to safer place out side device storage.
You may have received mail in case you freshly noted, if not check your spam else contact me with DM.
Thanks.1
Thank you, then I will unlock BL > flash ROM > set up everything > send mail via request code app. Then I will also receive IMEI backup tool I understand. -

After ROM installation, you may have stub (Magisk sortcut) for Magisk, you can click there and update. If no stub available, download Magisk apk from download and Install apk manually. If you are using same version of magisk then nothing requires to do for magisk.
- Select "Prepare device for dirty Flashing" from ROM Tool and straightway flash this verison of ROM with Odin. In case you are on older version of ROM and said option is not available in ROM Tool, manually delete *DrKetan* module(s) before flashing ROM
Installation : Notes included in ROM download area
Setting up device first time after ROM installation
- Check for Magisk app, if not available/only stub available, Install Magisk apk (get proper version from download area) → Open & allow run additional setup if asked for → Reboot
- Open ROM Tool from app drawer and Apply essential fix and Reboot,
- After reboot you can check SafetyNet and should be passed. You can use this app from playstore or This from Github to check SafetyNet (ROM Tool will offer to install this during Essential fix too)
- Now you can further setup ROM a per your liking.
- Since A12 new Magisk (Zygisk) doesn't have buil-in Module repo, You can get standalone module manager from here (ROM Tool will offer to install this during Essential fix too) For more details and queries about new magisk ref this
PS : Plz don't install any other mods for SafetyNet, All queries related to Magisk/SafetyNet will be ignored if already explained above

Known Bug/Tips/Fix

STATUS : Online
PS : This is a fully customized ROM and for end users only, ROM or any part of ROM not allowed to redistribute,modify or to use as base to prepare new ROM.5
You should able to downgrade as far as bootloader revision remain same. For example base of T07 is S918BXXS1AWD1
Here 9th digit is binary revision (1 in above value)
You can downgrade to other version as far as this 9th digit version remain same5
debloat all apps that are not needed
disable all apps that cannot be debloated and are not needed
limit background processes for all apps you think are needed, either:
- via the app's settings in Android
or
- via the battery settings in Android (there are more options, e.g. disable the background processes completely)
install magisk module "universal-gms-doze" to limit the background processes of google-play-service
set power mode of phone to "light" (battery and device maintenance -> battery -> advanced battery settings)
make sure in the developersettings that mobile data is turned off, if connected to wifi
assign a static IP in the wifi settings, if possible
disable "switch to better WLANs" in the advanced wifi settings
activate "WLAN energy saving mode" in the advanced wifi settings
disable "Automatically connect to Hotspot 2.0 WLANs" in the advanced wifi settings
in connections -> mobile networks disable 5g ("connect LTE/3g/2g automatically")
Tasker:
Create profiles to e.g.:
- With DND enabled (10pm - 7am for me) and screen off, enable airplane mode and reactivate when screen is turned back on.
- With VoWifi available turn on airplane mode/wifi and turn off airplane mode again when wifi is not connected
I may have forgotten one or two things, but these are the most important steps (for me)
It depends of course on your use of the phone, whether the steps are useful3 -

ROM Kernel: Stock (pre-rooted). Source code (samsung) here
ROM Firmware Required: Stock Samsung specified version
Version Information
Status: Stable
Created 2023-02-0913Installation, Important Infos & Download
Installation : State of the art Installation procedure.
- Only needed is supported device + Unlocked bootloader.
- No needs to have device rooted/Installed TWRP/update device to specific base
WARNING
Before you root your device you must be aware that
- This will void warranty.
- As of now you will lose Samsung Pay and Samsung Pass forever if you root once, even unrooting won't help.
- There are many features stop working when you unlock bootloader other than S pay/Pass like Samsung Health, Secure Folder, Galaxy Watch pairing issue, Issue connecting old gear watch (S3 or earlier), Google Pay etc but ROM is patched for all these mentioned features. Still you may trouble using some bank apps and these may fixed by adding these apps to Magisk Hide
- There may be some knox features there which you may not able to use but I can't list those as I never used. Just Google It
- Patched featurs are working today when writing this, No idea if it may stop working next moment/tomorrow or later
- Also to note, once you root, you can't go back to "pre-rooted" state completely. It is one way!
- OTA won't work on rooted device.
- ROOT with caution.
- On unlocking bootloader you will have warning screen while device boot and as of now no workaround to hide. Though it can be removed with re flashing stock rom + re locking bootloader
- You can unroot & Relock bootloader after flashing stock firmware, but still your warranty flag remain 0x1 and most of countries it still voids warranty. Also after unrooting & relocking bootloader, some knox features never work again.

12Important Announcement for T06 release
I am holding T06 because of Magisk 26.0 stable release just released. T06 test version is based on Magisk 25.2, one can install (update) to 26.0 easily but ROM Tool and Tweaks will have multiple things broken because of some changes in Magisk 26.0
I will re-release T06 with built-in Magisk 26.0.
@ Test users of T06 : Please don't update to magisk 26.0 else you may have multiple things broken.
