Is it possible to downgrade from cm13 to lollipop or cm 12.
You have a backup of your important data and a custom recovery installed, right?
0.- Download CM rom zip and GAPPS zip, and place them in your internal storage.
1.- Go to your custom recovery. Wipe Dalvik, Cache, Data and System Partitions (I use TWRP recovery on my devices)
2.- Flash the rom file
3.- Flash the gapps zip file.
4.- Reboot
If you want to go back to stock ROM, in the step 0 just download the zip for your device from this post and don't do the step 3 (these zips have gapps already installed).

So I would just boot into CWM recovery and then install the zip?
1. Nandroid your current setup (so you get back to where you are now)
2. put all the zips you plan to flash on your sdcard
3. reboot to CWM Recovery
4. flash new modem (if you're planning on changing your modem)
5. wipe data / factory reset
6. wipe /cache partition
7. under "Mounts and Storage", Format /system
8. under "Advanced", wipe Dalvic Cache
9. flash rom zip
10. flash kernel zip (if not in rom above)
11. reboot
read through the DEV section under [ROM].. and read the OP (post 1)... each DEV gives recommended steps for flashing zip (CWM) or flashing tars (ODIN). You may also want to use Darkside Superwipe to ensure you clear all previous rom traces prior to flashing new rom.
I have installed Philz Touch 6 and installed ROM cm-12.1-20151201-0012-UNOFFICIAL-p5110.zip from Andi and have tried a using the GAPPS Lollipop Base Gapps package for 5.1.1: gapps-511-base-20151205-1-signed.zip and when I do a reboot I get a bunch of google error messages.
Copy GApps and CM-Rom ZIPs to your internal SDCard (this works)
Boot into Recovery (this works)
wipe data factory reset (I go into this folder and there are two options I am not sure which one to select)
wipe cache (this works)
wipe dalvic cache (this works in the advanced tab)
format system
Flash CM-Rom ZIP from internal SDCard (this works)
Flash GApps zip from internal SDCard (this seems to work but I am not certain)
Reboot
no gapps installed
I tried a different approach and only installed the CM ROM and no gapps.
I have tried about 10 different gapps and none of them work with the latest build on my TAB 2 10.1 P5113.
With the ROM only everything seems stable.

So when we upgrade the system, it erases TWRP.
From the experts out there, I just want to try to get this clear on what we need to do to keep TWRP. This is how I understand the process.
1) Have a copy of the twrp.zip in the phone internal storage.
2) Download the full stock system upgrade zip file (not partial).
3) Boot into TWRP, and use TWRP to flash the system upgrade, and don't reboot.
4) Flash TWRP from phone internal storage to put it back. Then I'm good to reboot.
Look correct?

Hey guys,
General custom Rom question. Each time I install any custom, following the directions 100% it will never install properly. No matter what when I reboot back into TWRP it doesn't mount data.
Here's some instructions for an example from the latest one I tried Havok.
What am I doing wrong?
How to install
+ if you are coming from OOS then you will need to wipe your data as well as internal storage due to encrypted data but if you had any custom ROM before then just wipe data. No need to wipe internal storage.
for updating
1: Flash ROM
2: Flash TWRP installer
3: reboot again to recovery to boot from second slot.
4: Flash Gapps
5: Flash magisk
6: wipe dalvik cache and reboot to system.
That's all.
use tool all in one to decrypt internal storage

Hence it didn’t work you didn’t need to flash all of those zip but just format data.
Will this work for OnePlus 6T?
