I received a notification from ROM Manager that CM7 Nightly 19 was available.
It seems not a good idea to use this. I believe you need to format the cache partition first? And doing this thru ROM manager seems that it would not allow for that?
Anyone use ROM Manager OTA's successfully with CM7?
it does allow you the option of wiping the "data and cache" before installing, but i'm leary of wiping the "data" part. is that all our app data?
Yeah, with the Nightlies, I believe you can flash them on top of the older version without wiping data. So I definitely do not want to do this every night!

I flash my nightlies with out wiping.
Yes, I don't wipe the data, but I do wipe Cache Partition. Isn't that necessary? Or do you flash from Rom Manager as is without wiping data, cache, anything?
i wouldn't use rom manager to flash. use it to download and boot into recovery only.
also good for flashing latest recovery when needed.

So every single rom for any phone I've seen says to clear the dalvik and the cache (or maybe its just the "dalvik cache") but when I went from stock to Thriller, I forgot to, and nothing went wrong. In fact, all my settings and apps were all intact from the previous stock rom.
I've considered that the only other phone I'd done any flashing on was a backflip, without Apps2SD and maybe that's why all my apps and settings were intact, so that still leaves me with the question: why clear it?
This may be a noob-ish question, and I apologize. Thanks for any help!

If there are any compatibility issues between the apk dalvik cache of your previous rom and the apks on the new rom wiping dalvik clears the previous apks stored dalvik cache. In most cases you can flash without a problem. But I recommend wiping between rom flashes just to eliminate any potential problems. Flashing something like Thriller over the stock rom you can probably get away with not wiping anything since all the apks are essentially the same. Flashing kernels you don't need to wipe anything. When flashing a rom with a completely different firmware I recommend a full data wipe. Restoring recovery backups such as nandroid require no wiping at all.
Also, wiping dalvik shouldn't affect any of your settings.

When switching ROM with different base apps, it is generally better to wipe caches than to get stuck in a boot loop, or having your apps and launcher FC on you. You never lose anything as the cache rebuilds itself on the next reboot, except maybe a few minutes

If you followed the instructions you did a full data wipe. When you do this the dalvik gets wiped as well. To just wipe dalvik look under the Advanced menu in cwm recovery.

clearing cache
i am using a nand rom in my HD2, and i also want to install another rom via SD in Magldr, but because of kernel issues i cannot load the Rom from SD unless i use the kernal i am advised to use. I am instructed to clear the dalvik and cache, but does this mean that i would lose anything from my current NAND rom? I still want to be able to use that of coarse so i just want to make sure there are no major risks when clearing cache.

Clearing dalvik and cache wont make you lose anything, used to do it with my shift because I'd flash about 10 zips a day sometimes...
Also when it comes to flashing any ROM I format system data cache wipe dalvik cache and do a factory reset just to be sure nothing from a previous ROM is left over also wipe my SD ext partition when running an a2sd ROM, my question is can I safely manually format the emmc partition of the thrill from the mounts and storage option of cwm

Is it possible to update the current ROM version without wiping the data and apps installed on the current ROM version.
Currently I'm using squadzone's ver5.2 and I'm planning to use the ver5.3.
Can I just install the ver5.3 without wiping my current data and apps?

Though this is not recommended, you can try not to wipe data and apps.. If your phone boots to homescreen after you flash 5.3 without wiping, well and good.. But if you get stuck on the boot splash screen, you have no choice but to do a data wipe.. Best option is to backup app data with TBP (Titanium) and restore them after you do a clean flash, that is wiping data/reset, wiping cache..
Hope you press the Thanks button if my post helps..
kitrax59, it is not so bad as you think. I tried lots of times to jump from one CyanogenMod to other without wiping, and it worked rather OK. i didnt notice any problem. ecyaj, you may not wipe, but if you notice some bugs - it is recommended to wipe data
Thanks for the info GallardoSD..., but it was too late. I just wipe everything and installed squad's new v5.4. I used TBP and did restore them after flashing. It was just I need to setup everything again...
When applying an update to a ROM, is a data wipe always required, or can I simply flash boot.img and the .zip over top of the existing installation?
More specific to my situation, I'm using Albinoman's CM11 ROM; if anyone has flashed the December 10 update without wiping data, did it fix the black browser issue or would I need to do a wipe? I'd post this on the ROM's thread, but I don't have ten posts yet.
EDIT: Wiped only Dalvik and flashed the update, works smoothly and the black browser bug is fixed.

I have found clean wipes the best but use the recovery option to reload certain data etc or back up apps and reinstall clean.
Basically, i back up contacts, calendars, sms etc anyway these days. Makes for an easy transfer of data when needed.

If you are updating the same ROM... Usually you don't need to wipe... Anything more than dalvik cache and cache
However... EVERYONE will ask you and then suggest a full wipe if you have any issues...

Stupid Noob question... Once a Custom ROM (CM or SlimLP) has been installed..
- What is the easiest way to keep it upgraded?
- Are there OTA upgrades for them?
- Or only flashing a newer ROM version is the only option? If this is the only way, what is the best way to preserve the apps and settings?
The easiest and safest way to keep the ROM updated (from what I know, anyway) is to download the newest version of the ROM and clean flash it (erase system, dalvik, and cache). I don't think there's OTAs for this version, as none of the ROMs here are official. When you flash a newer the ROM, all your data will be saved, unless you wipe internal storage.

That's not a clean flash, that's called a "dirty" flash.
User data and settings are retained by doing a dirty flash but if you experience any bugs or problems after a dirty flash, then backup your apps, user data, settings & do a clean flash instead. Backup using Titanium Backup or your choice from the multitude of backup apps.
Dirty flash = wipe cache, dalvik cache and system.
Normal clean flash = wipe dalvik cache, cache, data and system. Always do this if you come from stock or another rom.

Think it'll depend what you restore from Titanium as to how clean it remains afterwards.

so if you already have installed SlimLP and want to upgrade and not lose your stuff, do a "Dirty flash"?
Yes.
But if you see any problems after a dirty flash, refrain from posting about the problem. First do a clean flash then check if the problem still exists.
thanks for the info all!
Apologies for duplicating this post but the original forum was apparently the wrong spot for this.
I need either some pointers or a reference to a how-to, if you please.
My Nexus 6 is currently running Pure Nexus 6.0.1-2060821-official, security patch 8/5/2016 with ElementalX kernel 3.10.40-ElementalX-N6-3-20.
I've updated Pure Nexus before through TWRP and all went well, but those efforts never involved updating the kernel too. I've attempted to flash the new kernel, the rom and the google apps, but the phone goes into a never ending boot effort and it's a tussle getting back to recovery mode as it tends to boot loop. The flashes are preceded by clearing Delvik and cache and cleared again after the flash.
Is the order of flashing off or perhaps not enough clearing of other items such as system? Or is a factory reset needed?
Kind of lost on this one and can't seem to string together enough search terms to find help specific to the problem.
Any help would be appreciated.
The kernel is most likely not updated to work with the rom. Each rom comes with its own kernel so you really don't have to flash a new one. I would flash the rom and gaps and see what happens. Leave the kernel out of it for now. You have to remember that not all kernels work on all roms. Many roms are making it so only their kernel works properly.

Still no-go. Freshly downloaded purenexus_shamu-7.1.1-20170215-OFFICIAL and Full_Dynamic_GApps-7.1.x-20161215, checked the MD5s, and flashed both after cache/Dalvik. Still got the same 4-color bouncing dots. Let it run like that for about 40 minutes before getting back into recovery.
Ran the same flash but this time also wiped system. Same result.
Is 40 minutes enough time? Impatience maybe?
Now back to original 6.0.1, PureNexus 6.0.1-20160821 and 3.10.40-ElementalX-N6-3.20 kernel.
Any ideas?

You are doing a full wipe right? Wiping system and data before flashing?
Also encryption could be an issue. If your device in encrypted or the kernel did not remove the force encryption flag. That could take awhile as well.

Get the Feb 15 GApps too instead of the Dec 15 GApps. Don't use old GApps.
https://forum.xda-developers.com/android/software/gapps-dynamic-gapps-t3487192
Also make sure that the GApps are 7.1.x and not 7.x.x or you get a SDK mismatch. What does the recovery log show?

Got the Feb GApps, wiped Dalvik and cache... this time I let it run for a bit over an hour in case the encryption was an issue. There's a little over 19 GB in files. I figured an hour would be enough but no luck. Had to recover again from backup.
TWRP gives 5 items that can be wiped, Dalvik, System, data, Internal Storage and Cache. I was of the understanding that data pertained to user data (photos, notes, etc). Most all of that is backed up but I'm unclear on what needs wiping for this Nougat upgrade. When I wiped system, it didn't seem to help - although I was using the older GApps at that point. I've seen documentation that says to wipe these items at the outset and others that suggest after the flash is complete. Both? Which ones?
I don't want to resort to drastic measures if it's something simple that I've missed.
Needs Nougat bootloader and latest radio--flash in TWRP. This allows flashing N ROMs while will still work with all MM or even 5.1 ROMs

What TWRP version? Old one cause problems on newer ROMS. Newest is 3.1.0, but 3.0.3 or 3.0.2 should be ok.
Wipe everything - /system, /data, /cache. /dalvik. Do NOT wipe Internal Storage (camera photos, downloads, etc.) before flashing. Data is usually app data, so make a nandroid first to save it, but app data can usually be restored with Titanium Backup or Google will restore it on setup. Just do not restore any system data.
Bootup on clean flash does take time, but normally no more than 20-25 minutes.
Try reverting to stock
Install stock firmware using adb
TWRP version might be the glitch.... Mine reports 2.8.5.0 in recovery mode. I'll update to the latest and retry after wiping all but internal storage. If that fails, I'll flash the boatloader and radio.
Once more into the breach.

Hi... Save your internal storage before processing. Just in case... TWRP 2.8.5.0 is pre nougat and incompatible.

You should really update the bootloader/radio to the latest once you update the TWRP. Updating the bootloader/radio will not affect your internal storage.

Wiping system, data, cache and Dalvik seems to have gotten me to Nougat but apparently root did not come along for the ride. Wasn't expecting that. Is that par for the course?
