Which is the proper way to downgrade from cm11 to cm10.2?

I upgraded my p1000 from cm10.2 to cm11 few weeks ago but the latest cm11 seems to be a bit laggish on my device and I'd like to go back to cm10.2, first of all... is it possible? If so, which is the proper way to do it?

I'd recommend you try OmniROM Its what I'm using on my "P1" and although it has its share of problems. Wired Headsets don't seem to be working. Its no more worse then CM10 was, and on that note why CM10.2 which like CM10.1 was broken beyond use? The only decent CM10 was CM10 from 2013 - 02 - 03. Which AFAIK was the last fully working CM10 Mod for the P1000. As the 10.1 and .2 had the Camera Bugs.
In any case Omni is pretty well supported with near nightly, or at the lest every other night updates. As long as you don't get crazy with it with Live Wallpapers, like my Old man was trying to run on it. (He too has a P1000), its pretty damned responsive. But. Again you ONLY have 512MB of RAM on the P1000. In some rear cases even less then this!
In my Fathers case the same sh-- that was causing his CM11 to lag like heck, was the same crap that was making the fresh install of his CM10 (version as dated above!), lag just as bad. So you might want to first clean up such resource hungry Apps as you have first.
But, on the Latest OmniROM for the P1 (Int't GSM version), as of 06.08.14 (Which is still the the most current at the time I wrote this), just running the Google Now Launcher, and a few widgets. The Tablet doesn't feel any considerably slower then it did back in CM10, and the Google Now Launcher is a KEEPER! I can't imagine wanting to roll back to CM10.
P.s. Did you remember to reset your Firmware + wiping the Cache Partition, and Dalvik Cache? This could also partially explain your problems. If you, had not done this.
P.p.s. Download your ROM, and appropriate GAPPs Package, then reboot your P1000 by pressing both the Volume Up, and Power Button till you see the Galaxy Tab / Samsung Bootloader Screen. Then release the Power Button, while continuint to hold the Volume Up till you fully enter the Recovery Mode.
Once in the Recovery Mode do the following Factory Reset, then Wipe Cache Partition and the Dalvik Cache (Advanced Settings). Then install your CM10.x ROM from where you stored it i.e. the /Download Folder? And when thats though. Your GAPPs Package as well. After which you then boot into your new ROM. Which might take a few moments longer, on the first boot as the Database(s)? have to built from scratch again.

Mmmhh I think I'll follow your suggestion and I'll try OmniROM. Have you used the CWM recovery or the TWRP suggested on their official wiki to flash the omnirom?

The way I described it before was for CWM. OmniROM uses TWRP. The ideas the same, in fact its a bit simpler on TWRP, in as far as it simplifies the wipe progress. Just One TIP download and install SuperSU, and run it. Once your rooted, go into your System Settings and click on the SuperSu Setting, (near the bottom), and it should ask you if you want to use a backup script, to keep root! You should run this if you want to... Need to keep Root for say AdAway. As OmniRom does NOT ship out with Root... WHY?! I can't say.
Other then that the only other annoying things I dislike about this ROM is that I have to keep uninstalling the Apollo Player. as well as reinstalling the Xposed Installer reset the "ro.config.low_ram" from true, to false, to re-enable transparencies, as well as other Lock Screen Widgets. After each update. Which again averages about every other day. I use something called ROM Toolbox Lite to do this, as trying to do this manually I always seem to gimp my install to a point of bootlooping.
But, other then these little niggles I actually like this ROM! for the most part.

And we should discourage question thread in development forum.

Clean Install?

Hi all,
I have a Z3C running the latest version of Android (for me), 5.0.2.
I've noticed the phone is running a bit more slowly lately (though not hugely) and I'm wondering if a clean install would be beneficial. I upgraded from KitKat to Lollipop without wiping the phone, I'm not sure if that would have any performance impact.
How can you do a clean install on Android? Is it as simple as reinstalling the software from Sony's PC Companion? I'm not sure if that is a true clean install or simply a reset to defaults.
Any tips would be appreciated!

Mostly 5.0.2 ROMs have bugs. You need to wait until Sony releases it's next version.
Clean install:
If your phone is rooted and have recovery install (cwm or twrp) you can do a clean install.
It is the process of wiping/deleting
system+data+android secure+cache+dalvic cache ( in short deleting everything) and flashing ROM.
As the data (junk) from the previous version remained after updating to newer android version, it gets cleaned and phone works well.
Hope you understand 'clean flash'

Thanks for the reply! A clean flash sounds like it would do what I want, but unfortunately my phone isn't rooted, and I don't particularly want to root it. Is there a way to clear everything out and reinstall without rooting?
I'm looking for something similiar to how you can restore iPhones.
Thanks!

You can try full factory resetting phone through stock recovery. To do so follow below steps;
1. Switch off your phone.
2. Switch it back on and the time when you see your phone’s LED notification light turn Pink! (or any other color) — start pressing either the Volume UP or Volume Down key a couple of times to make your phone boot into stock recovery mode
3. Once you’re in recovery mode. Use Volume buttons to navigate Up and Down between options and Power button to select an option in recovery.
4. Select wipe or factory reset (similar to this)
5. Reboot
Also after this process, open your file manager and delete 'Android' folder from both sdcard & ext sdcard (phone will start hanging) and restart.
(This process will delete app data,cache & their folders)
(A deep factory reset)
If still your phone behaves similar like previous, it's software issue, you need to wait for an update from Sony

Rooted or not, personally I do a full factory reset aka "wipe" aka format at least every 6 months. Just like a PC, apps you install and uninstall leave crap behind that clogs up the file system. Seems like there's always some Google bug every 6 months, too, and a wipe seems to resolve most of them. There's no harm in doing it. I do not let Google back up all my settings, b/c I prefer to manually set everything up after a wipe (esp since I may be wiping due to some setting anyway). I'm not sure, with the ridiculously powerful phones these days, if wiping will actually speed things up. For me it's more of a spring cleaning type of thing. Er, I guess more like an anal retentive geek type of thing

Problems with Android N Preview and Unenrollement

Good Morning Everyone! I decided to open this discussion hoping someone could help me solve or at least understand the problem I have been having on my Nexus 6 with Android N Preview. So, I have the Nexus 6 since April and I got it from a friend who sold it to me. At that moment the phone was already enrolled in the Beta Program, and was running one of the first previews. But here came the problem. In fact I wanted to unenroll the phone but when I enter the Beta Program page, my Nexus does not appear as eligible device nor I can unenroll it from there. I looked at Device Manager and it shows my Nexus 6, but I actually could not do anything to unenroll it. I tried flashing a Marshmallow build with NRT but as soon as I turn on my phone, an annoying notification shows up, saying I can update to the N preview. So, how can I try to uneroll my Nexus 6? My friend says he is not able to do it for me, cause he doesn't see the device on his account anymore. What do you suggest me to do?
Thanks in advance, guys!

Here is an idea.
When NRT is used Twrp-recovery is installed.
Copy a lite stock rom in 'zip-format' to internal memory. Or download it.
http://forum.xda-developers.com/showthread.php?p=59561445/
Reboot in recovery and wipe the system partition and caches.
Still in Twrp-recovery - Flash the 'zip' with lite stock rom.
Reboot.

Thanks for your tips, man! I have some questions about: with this procedure I'm going to install a custom ROM, but if I wanted to go back to latest official MM build and flash it with NRT, will be the problem solved in the same way in your opinion or will I get the notification about the preview again? What if I try to access with another different account after that in your opinion?

You need to delete the current account and do a factory reset.
For going back to stock there is a tutorial,
http://forum.xda-developers.com/showthread.php?p=57063390/

So I managed to go back to android MM after enteting a new account and unenrolling my Nexus 6 from Beta Program. Now everything seemed fine but then after I updated back with the OTA I received, I noticed my device has still July Security patch. I thought Google would have sent me September ones, so I tried to check manually and waited a whole day, but nothing happened. Coukd it be a problem related to bad installation in your opinion? Do you suggest me to restore September build through NRT?
Thanks for all your help man, I owe you and thanks you for your time!

ANCIENT Android

I have quite an old version of Android on my Nexus 6 (see attached). Is it safe to flash or fastboot to a 7.0 or 7.1 build without wiping? I am on rooted Project Fi. I don't necessarily need to keep root (though I prefer it for tap-to-wake), but I do need Project Fi compatibility since that is my carrier. Thank you!

You are going to have to wipe data and cache, flash bootloader and radio, and then you are clear to go to 7.0 or 7.1! *project FI is not a custom rom thing, its going to work now with any rom! Root is as easy is reflashing SU when done with upgrade, if you want root again.

While you probably can receive OTA updates until you get to Android 7.0, there's no guarantee that you'll get the required updates. Flashing one of the OTA images from the Google Developer website will get you there a lot quicker. But you want to back up your internal storage onto your PC before applying the OTA. Since there is a bootloader update involved, your device may end up wiped.

Darn. Can you link me to whichever bootloader, radio, and build would be best for me to use? I just want the base stock Project Fi build, so I'm not sure if I should get the Google build, or one in the dev forum.

I cannot utilize OTA updates: I click install, it reboots, and fails. Hence why I have been on 5.1 for years. I just haven't had the time (or desire) to do all of this manually. How should I go about the upgrade process? I understand the process of fastboot and all that (though it has been a while), but I need a little guidance on which file (or files) to use and where to download them. Any pointers on which website and which download(s) would be much appreciated, whether it is the official google file, or I need other files as well, etc.

This is a link to the 7.0 bootloader and radio, both flashable! http://forum.xda-developers.com/nexus-6/development/fxz-nexus-6-recovery-flashable-fastboot-t3066052
This is a link to a stock (project fi ready) 7.0 build, with radio / bootloader/ rom / gapps / everything. Perhaps it would be easier just to do this writeup! http://forum.xda-developers.com/nexus-6/general/android-nougat-nbd90z-flashable-image-t3474572

Excellent thank you. Regarding the second link:
a) This will work for 5.1 and a very old version of TWRP correct?
b) Also, what is the purpose of making a backup if this will wipe the storage anyway?

Of course it fails. OTA updates require the stock recovery to work. Had I known you had TWRP installed I would have had you flashing the factory image using fastboot.

a) no, while it may work, You should definitely update your version of TWRP
b) You aren't going to wipe your internal storage if you use TWRP. that's only when you're flashing via fastboot
If you use TWRP, you can wipe the system, data, and cache without touching your files. just dont' wipe internal storage

Yes. I do have TWRP. In that case, do you agree with the other post that the following link is the best upgrade path? http://forum.xda-developers.com/nexus-6/general/android-nougat-nbd90z-flashable-image-t3474572

Ohhh I see. My eyes immediately skipped to the "Method 2" content.
a) So I should first update TWRP, and then perform "Method 1" in that post, correct? Just want to make absolutely sure of the steps.
b) In the case that Method 1 is correct, since my data would remain, will my phone be wiped or not?

Yes.

It worked! I am now proudly on 7.0 without wiping!!! Thank you!!!!!! How do I mark this as the answer? Woohoo!!!
P.S. In case this should help anyone else (or maybe help myself in the future), I updated TWRP though the "TWRP Manager" app, did a full backup of the phone (took 822 seconds), then flashed that zip in that other thread. So far so good!!!

Woot!

Updatet my rooted OOS over the Air, now I haven't TWRP and SuperSu

Hi There,
I've the Problem that I havent't TWRP-Recovery and SuperSu after Updating to OOS 4.1.1 and Android 7.1.1.
Do someone know if i had to flash TWRP with qiping all Data? Or is there a Way to Flash TWRP and SuperSu without wiping? =(
Sorry I'm new to Android and started with the oneplus 3t. So i didn't know that i hadn't to update the Phone.
Or is the best opinion for me to choose a custom rom? But there are so much, i don't know what to choose.
Thanks for help! =)

Neither TWRP nor SuperSU will wipe anything.
It's totally up to you whether you need a custom ROM or not. If you want features like switching tracks just with your volume keys, you'll totally need a custom ROM since stock ones don't provide this feature. But this is just one example of many.
Regards.

Hm okay, cause when I got my one plus I flashed trwp and had to wipe everything, cause of the encryption or something like that.
I'll try my best today evening, hopefully nothing will go wrong :-O
What do I need to center the clock?
I'll flash trwp and supersu and anything to center the clock today evening.
Don't know if I need a custom rom, are there reason for a custom rom?
Thank you so much!

If you need help with anything, just ask.
I never had to wipe anything. I just wipe the phone when I want to remove the encryption.
EDIT: regular security patches is one big reason for me to install a custom ROM.

Thanks, I'll ask my questions
But why did the update delete trwp and supersu?
I was happy with OOS but missed the future of centering the clock.
May I ask which custom rom you use?

Updates remove SuperSU because they essentially flash over all non-user partitions (everything except /data, where your files, settings and user apps are stored). To root the OS, SuperSU installs its files in the /boot partition, which gets overwritten during ROM flashes. Root gets deleted any time you flash any mod (including most custom ROMs, since they also replace /boot). The only exception to this is if you flash a custom ROM that comes pre-rooted.
TWRP does not get deleted immediately during flashing, but rather when you first boot up afterwards. OOS will attempt to replace any custom recovery with the stock recovery when it first boots up after updating. You can get around this by either flashing TWRP again, or rooting immediately after flashing a ROM update, before you reboot (flash ROM, wipe cache/delvik, flash root, reboot). Most custom ROMs will not replace your custom recovery.
There's a few threads containing OPSystemUI.apk mods in the Themes, Apps and Mod section, though most of them also contain a bunch of other graphical modifications. If you only want to center your clock and nothing else, it can be achieved by modding OPSystemUI.apk yourself, though there is a bit of a learning curve to it.

You are mixing things up a bit but don't worry, I'll explain.
You need to unlock the bootloader first, and that always wipes your data for security reasons. So if your phone is stolen, the thief won't be able to access your data by installing TWRP or a custom rom. After unlocking you install TWRP (custom recovery), and use it to flash stuff. (roms, mods, etc)
After that you only lose data if you (or a rom) mess things up, and your data becomes unaccessible, or you relock your bootloader for whatever reason. That's why you should always backup to a computer before doing major flashing/upgrades, etc.
If you upgrade the rom you'll lose root and/or TWRP, but you can flash it again as explained by others.

Hi there,
so I've flashed TWRP and SuperSu again. You are all right, i haven't to wipe anything. I really mixed up things. But now everything is working for me.
Okay, i have to learn how to get my OPSystemUI.apk modify it and flash it back?
I will seach the threads and learn.
