Is it possible to downgrade from CM14.1 to CM13 via DirtyFlash?
Reason is that xposed is not working on Android N yet and i want to DirtyFlash, because i do not want to wipe all my datas / make a factory reset.
I have a G900F.
Why not to backup Ur data by titanium backup :/?

dirty flash will not work. use TiB to back up the stuff you want to keep, go into TWRP, use the advanced options file manager to delete the android folders from both internal and external. Wipe those 3x each (yes, 3x) and then do a factory reset and install your CM13 variant and restore your stuff via TiB. Thats the only sure fire way to get this to work.

Hi Guys!
Unlocked, flashed TWRP and rooted phone via twrp su for the first time in my life. Next move is installing custom PA rom. After browsing xda and other sites for many days to learn how to do it, basically, its just doing it in trwp recovery mode the factory reset, clearing cache and clearing delvic cache, then install rom and gapps then clear again then you are done. Is this right?
now, about factory reset, clearing cache and delvic cache in twrp, when you do this, does it in anyway delete or removes any data or setting in my phone just like when doing it in factory reset in the "Backup & Reset" in "settings" or just like what happens when you unlock/lock your phone? Or it does not really "erase anything"? Coz I do not know if I should backup first and if I must back up, I do not know which to backup or if I should have to make a full backup? Because I might not have to do backups after all for flashing PA custom rom and save time and internal space. If clearing caches and factory reset in TWRP doesnt really delete or mess up anything in android mode then I will go ahead now and install the custom PA ROM. so I need your advice before I proceed.
About flashing back stock recovery, I DL the stock 4.2.2 rom from google dev. do I just flash recovery using this file or is there another specific stock recover file to DL and flash into the phone just like what I did when I flashed TWRP which I was able to DL from goo.im?
Hope you could help me with these clarifications. I did try to search and learn from different threads about this but I not 100% sure I understood it correctly. So I made this thread to make sure of facts and clarify these things.
Hope you could enlighten me. Thanks!
Isn`t this clear enough!
Quoted from PA OP:
INSTRUCTIONS,
1. UPDATE RECOVERY
2. FACTORY RESET
3. INSTALL ROM, GAPPS, FIX-IF ANY
4. WIPE CACHE & DALVIK CACHE
5. REBOOT
PA 3+ UPDATES DO NOT NEED A FACTORY RESET,
BUT YOU NEED TO INSTALL GAPPS ASWELL.

I hope you would be considerate enough that I have no experience yet on this and I did some browsing and learning thru the guides and threads here in xda and other forums which is why I know the proceedure. I was only clarifying some things this matter that I have quoted now.
also, if someone would be kind enough to lead me to a link where I could find a stock recovery img. the only latest I have found is not JDQ39.
Thanks
Perform a backup of your current ROM first as this will be replaced by paranoid and all app data will be lost when factory resetting.
I don't know where all the need to wipe caches comes from.
Wiping cache and dalvik cache will not erase any of your data
Factory reset will erase all user data (apps, app data, signed in accounts, phone contacts (Google contacts will be downloaded again when you sign into your Google account during setup of new ROM) and SMS messages etc.
Here is the process I usually follow.
Place new ROM & gapps on phone storage
Reboot into twrp
Perform a backup of my working ROM
Factory reset from main page in twrp (the one that says it won't touch your sdcard)
Flash ROM &gapps
Reboot
Once fully setup. Move my old backup from phone storage to pc

Thank you very much for the reply! So in making a backup, i could use the backup feature of twrp and this is enough and would make a FULL backup? Meaning all data, app, settings, vault app and files inside vault and go back into its original state as if nothing happened? Or i am wrong? Should i be making or using another backup method aside from the backup feature of the twrp?

The twrp backup is in essence creating a custom ROM of your phone. Exactly the way it currently is. Including all apps & their data.
If you flash a different ROM and decide you don't like it.
Restore the twrp backup and you will be right back as you was before flashing the custom rom.
If you factory reset (erasing all your data) then restore the backup. It will restore all your data etc...
It's just like a save game. If you mess up. Just reload from there
Note it's not the ultimate tool. If you mess with partitions that are not included in the backup then you might have problems. But for the average user just flashing custom roms . it will backup everything you need

Thanks again for the reply. Now another clarification. So when you say the twrp back is just like making a rom of its current status or like a saved game and if i did not want the new rom then i could revert back to this backed up rom. So does it mean that if i install PA rom then restore the backup from twrp, will it overwrite the PA rom and go back to my original rom that i have backed up or will it only restore the apps and settings, etc.?
Also about this twrp backup, will it also backup and return to old state when restored certain apps like notepad and the notes i have saved in this app. The same goes to the vault app and all the files i have hidden in this app, will it back it up as well and will be restored?
Thanks for your patience..

Correct. It will revert the entire ROM back to what it was.
Basically how your device is when you backup. Is how it will be when you restore.
All app preferences and settings. All apps. Widgets everything.
The only thing it doesn't alter is what's on your internal storage
And a point to note.
If you make changes to contacts or have received texts after the backup. It will revert them if you restore back to what they were when you backed up.
It is just like turning back the clock on your phone. Putting everything back to the point you backed up except files you have put on to the internal storage

I think you are saying that you will want to restore data on PA. You can backup/restore data with titanium backup or carbon.

Whoops yes didn't read fully. You get no choice with a twrp backup. It's just the full lot that gets restored. If you want specific apps to be restored onto a new ROM you need to make backups of them using something like titanium backup on your current ROM. Then restore them on your new ROM.
You can use app like SMS backup and restore for taking your SMS history into a new rom

Thanks guys for the replies. Yes, what i exactly wanted was to install PA but be able to restore all data, apps nd settings back to what it was except that now it would be running under PA rom. If this is the case then titanium back up is what i am looking for? With titanium, is there a specific setting or option that i shld select or just press backup button? Sorry, its my first time to use titanium. Also, does the backup of the titanium also covers my notes on my "note everything" app as well as the files that i hid in my "vault" backup? Or should i make a separate backup using the apps on backup feature? And in the case of the "vault" app, should i unhide them first, backup with titanium then after restore just hide them again?
Im really appreciating the help..

I'm not really sure how either of those apps work, but I'm guessing your notes will be fine. You might have to do some experimenting with the vault app. You should do a TWRP backup in addition to Titanium. In Titanium Backup, you just press the batch button in top right corner and "backup all user apps/data" or whatever it says.
As far as system settings go, they should be restored if you choose that option after logging into your Google account (only during initial setup).

Side note: In order for batch processing to work within Titanium, you must purchase the Pro key. Otherwise, you will have to backup and restore each app individually.

Does that remove all the internal files?
Yes, it does. But there it depends on the recovery you are using. In twrp there is an option to wipe everything except the internal, but this is not recommand since you want to have a clean flash. Just make a nandroid backup.

Greetings all,
I have the i9500 S4,
I was running Hassan Rom and everything was fine, yesterday i've tried to boot the OzcanRom, and kept getting the (process.media. and process.phone not working)
The phone was not working, and after multiple tries of rebooting the said rom, i decided ill go unroot it and install the stock official rom (as i need my mobile for work etc...)
What i did is wipe the dalvikcashe and the system files (which i think was wrong) and tried to flash the stock rom via Odin the old simple way.
Everything went fine, when my mobile turned on again, i kept getting the same messages:
(the proccess android.process.media... & the proccess android.process.acore... & the proccess android.process.phone... Unfortunately email has stopped...& the new message Unified Deamon (EUR) has stopped.
The mobile is useless, can't access anything, can't connect to USB media so i can backup the files, can't connect to WIFI as it restarts...
Please help me guys as soon as possible i really need my mobile for my work...
(Preferably without a full wipe, or if necessary offer a backup way for my gallery)
Should i try installing a different stock rom? as i chose one from SamMobile that was the closest to my region...
Perform a factory reset. You can do that from the recovery or from within android. Make sure to backup the files on your internal storage.

Thank you for the reply.
I can do that, but i can't backup the files as nothing on the phone is working, pressing the gallery button for example, leads to the (process.media not working) message.
Any other solutions? i don't understand, isn't flashing a stock rom supposed to solve all these issues? should i try flashing another version of the Roms (different region perhaps)?
It does solve it, but you need to factory reset.
What I would do:
- Flash a custom recovery.
- Do the wipe option prepare for new rom.
- Flash stock/custom rom.
That way your internal storage won't be wiped.

Then, Do the wipe option, which wipe option, the recovery i had had only 1 wipe option, how do i know its not the one that's gonna wipe my data)
Finally, ill flash the rom. (Do i need to root my device again then? to flash a custom rom, if yes, im just gonna go with stock rom and let my mobile work for a few days where i need it then root and install a custom rom again)
I really appreciate your help, and your prompt answers.

- You can use Philz recovery
- You know the wipe option when you see it. The one that say prepare for new rom. No custom rom will wipe your internal storage. That option is somewhere hidden.
- You don't need to root, just flash.
ps you will lose all your apps. It will not wipe your internal storage.

Hello ,
im running mm pure 2.8 and i have a lot of stuff on my phone
how can can i wipe all those and reinstall the same rom ?
like installing a rom on a new phone
:S
Easy.
Backup your apps if you wish with TiBu backup your SMS and call logs with SMS backup restore.
Backup data if you want to format phone memory or SD card.
Download new ROM you wish to use.
Boot into TWRP then wipe advanced select what you wish to do. If you wipe internal and external you will need to put the ROM you downloaded onto a USB and USB otg and flash the ROM through TWRP or remove sdcard put it in your PC and copy ROM to it and flash that way. Then you will have a fresh phone and then restore everything back.

first off all thank you
so i can wipe every thing and install the rom from memory card without installing a fresh android M ?
So your running 2.8 TruPure ATM. Just download the new update of it from the thread. Then if you want to format your internal or external memory you will need to backup photos music videos etc if you want to keep it. And again like I said use SMS backup restore to restore sms'. Then use TWRP to wipe what you wish. Then reflash. But really if your not sure your better searching and reading up more before you jump into rooting and flashing custom ROMs etc if you don't understand the basics.

I wish to move from stock b574 to sokkoban's.
My biggest concern is that in the description given, it requires wiping data. Given that I am already on marshmallow, is there really a need to wipe data in twrp? Won't cache/system wipe just do? I don't want to wipe my internal sd plus file structure/dates. Plus all my apps!
Call me lazy but am yet to find a backup system that will return all my files & apps as they were pre-flash.
Any ideas?

actually, huawei has pre-installed backup app.. and it works great... you can backup every app plus app's data too... but backing up all those may take time..

in teory no you dont need to wipe data ...
as you know sokkoban rom must be installed via twrp
so you can :
fisrt
install twrp
make nandroid backup
install sokkoban rom without wipe
if does not work you can try to
wipe and install sokkoban rom
recovery from your previus backup the data partition
Thanks guys. I can confirm you do not need to wipe data to use the custom rom. A simple dalvik & cache wipe did it.
