Before moving to satbale A12 release, I am preparing R11, last A11 based ROM. for those ho are yet not ready for A12. Indeed actually it was prepared but haven't tested,now I ill test and public it.

One more thing, If you waiting for Stable A12 (S1) then make backup of your data, This time I am not going to provide any extra files so you must have to flash stock satble once before flashing S1. This is requires because with major OS update there may be many thing gets changed and always recommended to go full clean. May be tomorrow release R11 and then start working for S1. (based on stable A12)
Thanks for patience.

Finally flashed A12 stable and rooted it. All set to prepare S1. Hopefully will be ready before weekend.
Guys don't forget to make EFS backup and store to safe place just before and after major OS update.
@dr.ketan , Can you please confirm again what we need to select in TWRP to do a backup, i.e. Super.img, EFS etc... I don't want to select more than i need to...

Finally, im guessing the process will be:
Install stock A12
Reinstall TWRP
Flash Super.img, Ketan Rom Zip, flash BL/CP, reboot, apply essential fix etc?

Will there be a newer version of TWRP that we will need?

Cheers

Boot,recovery,super,optics and product and data should be fine . Though restoring data have some issue on A12
Also data shouldn't be restore on different rom. I mean for example data backup of Sb1not to restore on sb3
What is eveyone using to backup call logs, sms, whatsapp for the purpose of migrating from A12 beta to stable?
Swift backup all in one go
For wa also manually copy WhatsApp folder from int storage /Android/media/Com.whatsapp

Here some my thoughts and explanation about TWRP backup and restore

Firstly brief explanation about what does partition contains.
  • Boot : It is Kernel
  • Recovery : It is Recovery
  • super : That contains odm,product,system and vendor partitoin all togather.
  • optics : CSC files (where we routinely making changes for csc features) and network settings depending on your carrier
  • prism : carrier related apps and other stuff . In odin when you flash CSC*_ or Home_CSC* these two optics and prism gets flashed.
  • data : That is all your installed app and made changes in settings

Now what to backup/restore?
  • boot - Helps if something messed up with magisk or waht to restore kernel after flashing custom.
  • recovery - usually it doesn't require but if you flash some other recovery(TWRP) and you want to restore one in backup, that helps
  • super : As stated above these is main system, if something you have messed up in system/vendor (usually with flashing something, or erasing something) you can restore by super.img.
  • optics and prism : as explained above are CSC files, Rather than restoring it, I prefer to flash HOME_CSC*.tar.md5 to make csc compartment clean. So to backup or not not much important.
  • data : This very sensible part. I prefer to make data backup when there is no samsung a/c or Lockscreen protection there. Also don't restore it cross version of ROM. Also some common mistakes user making is, He/She clen install ROM and then restore data partiton of previous ROM. This is worst then even dirty installing ROM, never do it. It is just false sense of satisfaction that you made a clean install. According me, data partiton backup best to be made just after complete clean install ROM and setting up device without adding any account and lockscreen protection. So when you restore this backup, you will have a device just like you recently completed clean install and save your time to setup initial wizard
Backup Application,Call logs,Contacts,SMS etc

Titanium backup was ruling for decade for these but since A11 it's not trust worthy and on A12 almost useless.
Swift Backup is now my choice (Some other like Migrate, App dash (by RD XDA dev flar2) also alternatives)
For contacts : I do prefer google sync. Just adding google ac everything will be restore on it's own, provided you are saving contacts in google. In case you want to make off line backup of contact, there is a built in utility in phone. Contact - settings - export - This will create a file. Similarly browse same file while you want to import contacts. Catch in this is your contact image will not retain size and it just backup thumbnail picture.
Only one utilility I have found that makes offline contact backup without distoring image quality is My Phone Explore client (needs on both PC and Phone). Also this utility is best for wireless file manager.

Schheduled backup - A must needed utility.

I always prefer clean installation (Factory reset withot wiping media files) and really it takes less than 30 minutes to setup everything.
If you enable schedule backup utility in your Backup app (e.g Swift backup have this) and make some profile like
1.Backup - new app at X time then it will auto backup all app that you have new installed at given time
2.Backup updated app at x time - This will make backup of any app that you have updated in store will backup at given time
3.Any app which get data changes frequently and you needs data changes like whatsapp then create a profile favorite app - add whatsapp in favorite and schedule it to make backup daily at given time.

with these your device always remain ready to clean install anytime instead of last moment backup or some urgent clean install needed.

Also Folder Sync is good utility if you needs duplicate copy of files from Internal storage with scheduled operation.

Hope this may helpful and answer lots of queries for many.

Samsung Health latest version issue

I can confirm issue is related to unlocked bootloader check implemented by samsung in new version.
I have disable it and now latest version is working. This will be a new headache to patch everytime. Also it seems more samsung app may implement this and those app may or may not work with patching.
It seems samsung now trying to make every trouble to root users. Pathetic.

I always buy latest S series, big money.

If they follow this practice, my next phone will be another root-friendly brand such as FairPhone or Fxtec. Or maybe a Linux phone such as PinePhone or Librem.

I don't want to be jailed.

    Important Instructions for setting up ROM (NEW)


    - In case clean installing ROM

    • Since A12 Stable Magisk not working and new Magisk doesn't have buil-in Module repo, You can get standalone module manager from here For more details and queries about new magisk ref this (Applying ROM Tool Essential fix will offer to install this app)
    - In case dirty install (You can try if you are on DrKetan ROM previous version but we DO NOT RECOMMENDED)

    Installation and Download & Notes


    Important :


    - 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. (hope in future we can get it working on tripped knox device)
    - OTA won't work once you root device.
    - ROM Tool permission : Files & media - To save and read files, Calendar - Tool needs some time monitoring to avoid using RT immediately after reboot. Special access for accessibility service - Since Android 12 it requires for QS panel custom Toggl e.g. Reboot to recovery

    Installation :


    Read ChangeLog post for Installation instructions (link on post #3)

    PS : Who can handle consequences of dirty flashing, they never need to ask this question in forum. If you dirty install then handle it yourself .
