I can't update my N7100 from previous Omnirom to latest CM11. I wiped my phone, installing latest CM11 zip and phone is stuck at N7100 logo and restart to recovery. When I install Omni zip everything is working fine. I'm tried TWRP and Philz recovery but no results. Please help
did you wipe /system, /cache, /data and dalvik? (full wipe).

Yes of course but I think CM isn't extracting to /system because when I leave recovery it shows there's no root and asks if I want to install it.

Recoveries tend to do that... they do not detect superuser from any CM based ROM and offer you to install supersu after a ROM install and rebooting system.
I you do full wipes and you have tested latest Philz and TWRP recoveries... I can only suggest you to double check that the CM11 ROM is the correct one for your N7100.
It is strange that you encounter issues with CM based ROMs... these usually install without problems... I've encountered problems booting TW based ROMs, but not these. Sorry I can't be or more help. Good luck .
EDIT:: wait a second... according to your screenshot, you did a full wipe after installing the CM ROM... you are deleting your ROM that you just installed . The steps are:
1.- full wipe
2.- install ROM
3.- Install GAPPS
4.- wipe Dalvik <-- (some devs recommend this step, others don't... doesn't hurt to do it anyway)
Im on OTA N preview rooted
With elementalX kernel and twrp recovery
Is it possible to Flash a custom rom?
I only need to flash a rom and kernel and the vendor right?
Or do I forget something
I have no PC available for a few days

Correct, just flash the rom, kernel, and vendor in TWRP after wiping

Currently I'm following this process when I want a super clean flash of a new ROM
- Use Back2Stock script to get stock Motorola Marshmallow
- Flash TWRP
- Flash ROM
- Flash GAPPS
I keep coming back to these steps for one major reason : TWRP will not let me format or erase the DATA or INTERNAL STORAGE partition. This means that if I keep flashing different ROMs through TWRP, there will be junk data piling up in the DATA or INTERNAL STORAGE. But I digress..
I want to know if encryption is removed automatically when I flash custom rom like AOKP or RRemix? Does it depend on the ROM? Or should be including that RemoveForceEnc.zip in my steps?
Apparently those steps also cause my to not have root in my custom ROM.
The new steps I'm running now :
- Use Back2Stock script to get stock Motorola Marshmallow
- Flash TWRP
- Flash Fixed Firmware (marshmallow version)
- Flash SuperSU v2.79-SR3
- Flash ROM
- Flash OpenGAPPS (ARM version)
I'm no expert, but as far as I know you can only encrypt your data partition again from within Android Settings > Security. It won't be automatically encrypted again by simply flashing a new custom ROM.
Perhaps it could encrypt it when you flash stock, which is actually something I'd like to confirm because I removed encryption on my Z Play yesterday and am currently running LOS, so if I eventually flash stock again I wonder if it will automatically encrypt my data partition back.... I'm guessing no, but it's something I'd like to confirm (and/or try later on).
I don't have you TWRP problem, meaning I can format everything on my TWRP (if I go to advanced format I can select all options there and have everything wiped), but I usually simply do wipes on TWRP, then flash ROM, then Gapps, then boot, then install Magisk Manager (from Play store) and root from there.
Confirmed. When you flash stock you're re-encrypted (sad).
I'm running Android Oreo on the Beta line. I've felt that Camera quality used to be better in Nougat, and occassionally phone heats up with Oreo. So I'd like to switch back to Nougat. But I've seen a couple of threads mentioning about a potential data loss(whole internal storage getting wiped) and needing to install a rollback build before installing a stable Nougat ROM. Could someone shed some light into this? Is flashing the rollback build really necessary if I can flash the stable OOS 4.5.1 via TWRP? And, would I lose data in internal storage during the procedure? Thanks in advance.

I checked the thread and noticed that it's all about installing via the stock recovery. My phone's bootloader is unlocked and I have TWRP installed. So my question is, do I really need to install the rollback build? Can I not directly flash the 4.5.1 zip file via TWRP and be done with it? Or is there a purpose to installing the rollback version? I mean I read in that thread that after installing the rollback version via stock recovery, a factory reset should be done(which would erase the whole internal storage I assume?) and then the 4.5.1 zip file should be flashed. If I could use the advanced wipe option in TWRP to wipe the cache, data and system partitions and install the 4.5.1 zip file, do I need to go through the tedious procedure of installing via stock recovery, which would potentially erase my whole internal storage?

Why would OnePlus provide the rollback build if there are other reliable methods of downgrading?
I think rollback version is for stock recovery users and data loss + . And if you decrypted your data already downgrading is just flash zip in twrp and no data loss but you keep decrypt.

You mean the dm-verity thing? So it will be fine if I flash the Nougat zip file and install SuperSU binaries via TWRP to fix the dm-verity issue? That's what I've been waiting for as an answer. Thanks.
I am currently on the last open beta OOS, rooted with supersu and twrp-3.2.3-0. I know that i need to make a clean install of 5.0.8, so i shall wipe data/system/cache/dalvik, flash the latest 5.0.8 full zip, then reboot to recovery to flash magisk and then finally reboot to system.
My concern is - my phone is currently encrypted. Can i simply update as planned above, or do i need to take any additional steps to remain encrypted or go to decrypted state.
What could be the advantages of remaining encrypted or going decrypted?

Since you are on OOS (though beta), flashing 5.0.8 should not affect your encryption status. Your plan is ok.
Encryption is related to security. Decrypted means lesser security though I have no idea by how much. It is your call.
Yup, switching betweeb Beta to stable OOS will not affect encryption in anyway. Encryption will only be removed IF you manually format your data partition or the recovery does it for you.

Thank you. That was helpful. So in my case, i would have to erase data partition using TWRP to update from open beta to OOS 5.0.8, so the partition would get decrypted. But then i believe clean flashing the 5.0.8 zip would re-encrypt the data partition. Is my understanding correct?

No, when you "wipe data", it doesn't remove encryption. When you "format data", it removes encryption. I hope the difference is clear enough for you to grasp easily.
all you need to do is, if you have twrp, make sure you have OOS 5.0.8 zip, Magisk zip, working TWRP image - available in internal memory.
Then you need to Wipe System, Cache, Data - Do not check Internal Storage/Memory. or simply Factory reset from within TWRP. Then flash OOS 5.0.8 zip. Once it's done, flash TWRP recovery image from within TWRP. At this step, make sure you "reboot" back to recovery. If you will reboot directly to system, it will replace twrp with stock recovery.
Once you reboot to TWRP, flash magisk and you are all set!

Yep, i understand the difference in the operations on the data partition now. Thank you once again for the clarification.

One small addl. info. After flashing TWRP, there is no need to reboot to recovery. Simply flash Magisk right after TWRP and then boot to system. Flashing Magisk at that stage prevents TWRP being overwritten by stock recovery.
EDIT: or you can skip flashing TWRP and boot back to recovery after flashing the ROM and then flash Magisk alone before booting into system. Either way, you save one step.

I successfully completed the clean flash from last open beta to 5.0.8 and have magisk 18.0/twrp 3.2.3-0. Going forward, can i accept a new OTA update say 5.0.9 directly, or should i have to flash the full zip again? also would the process change when going to Pie later on?

I always download the full OTA zip and flash it manually wiping only system and cache/dalvik partitions, and I never had any issues whatsoever. Sure you will need to reflash magisk since your kernel and firmware will be flashed again.

Since you have Magisk and TWRP, the OTA either will not download or if it downloads, it will not flash. So you need to download the full zip (usually, the full zip will be automatically downloaded when the update detects changes to your system ie. root) and flash it. So long as you use the same above mentioned method to flash the full zip, Magisk will automatically flash going forward and your TWRP and Magisk will be intact. When going to Pie, since it is a different version ie. from Android 8 to 9, you should wipe system, data, Dalvik and cache before flashing Pie.
