[Q] About installing CM7 Nightly builds

Hey guys just a quick question about installing nightly builds on the nook. When Rom Manager asks whether to wipe data/cache and what not, if I select it, will it wipe the internal memory completely? leaving no user files behind? or will it only wipe the system files?

It will wipe everything and it will be a fresh install.

If you update, just wipe cache

It wipes the /data partition but doesn't wipe /sdcard /sd-ext or /met/emmc.

Just wipe Davlik.

if boot is longer than normal after wipe, it's normal!

Note: wipe cache and wipe Dalvik cache are 2 different things.
+ wipe cache is a quick way to clean the current running ROM
+ wipe Dalvik is a completely clean.
After wipe Dalvik, next time it boots, it will take a lot longer time due to the device has to re-compile the whole thing before ROM start running and booting.

I think I need to drop a few lines about wipe cache/Dalvik.
As I posted above, I said it wiped clean.
Apparently, I am NOT 100% correct.
I just updated to nb198, wiped cache (formatting /cache) then wipe Dalvik cache.
After done updating ROM, booting up, I expected everything clean, completely fresh.
It's not the case, I went to Market and all old search history were still shown. Not only with Market but other apps too.
So
a. either wipe cache/Dalvik is NOT completely clean wipe or
b. it was completely clean but somehow, those old cache info, which stored somewhere I don't know, get automatically restored back.

Okay, I did a quick read of the FAQ for CWR, and came across these:
Wipe cache partition
Wipes the cache partition of the device to clear all the data accumulated there over use. This is often used before installing a new ROM, app, kernel or any similar mod via recovery.
Wipe Dalvik Cache
Allows you to wipe the cache for the Dalvik virtual machine (the custom-built Java virtual machine for Android).This is required before most ROM installations and at other occasions too, for fixing some problems.
So, I'm taking this guide on board and will wiping Cache AND Davlik. So that's two steps prior to installing a new CM7 nightly build.

You didn't happen to store them in uSD card? Or perhaps app data/cache are separate from system data/cache...
Will look into it further...

ok thanks Vabs.
More replies about settings?

OK, here's the process:
0: Boot to CWM Recovery
1: Wipe cache
2: Advanced -> Wipe dalvik cache
3: Flash 7.2
4: Reboot
If it doesn't boot, just pull out the battery and go to factory reset. (That obviously wipes everything, but is still better than going back to stock )

So you saying only if it dosen't boot i should wipe everything by choosing factory reset, but if i was "lucky" and the phone boot i stay with all my apps and settings?
By the way, what cache and dalvik cache exactly are?

Cache is the place for apps to store all their temporary data files, dalvik is explained here: Linky!

[Q] Updating paranoidandroud rom guide

I know there's a lot of info on this subject, but im still confused about a few things related to simply updating to a new version of same rom.
some says i have to wipe all, clear cache and dalvik cache every time, others talk about dirty updating which i guess is without wipe, but do i still need to clear cache and dalvik, or just dalvik cache?, and do i have to flash gapps every time i just upgrade same rom?
like going from 2.50 > the latest 2.52, what i did was:
1. downloaded both pa_grouper-2.52-27OCT2012-190304.zip, and gapps-jb-20121011-signed.zip and put them in root of my nexus 7
2. went to goomanager and clicked "flash ROMs", where i selected my grouper-2.52-27OCT2012-190304.zip, clicked "Order and flash selected" and on next screen checkmarked "Wipe cache/dalvik cache partition"
3. clicked flash, and waited..
4. did same procedure (step 2 and 3) with the gapps-jb-20121011-signed.zip and now im not sure if that all i needed to do, or if there's something i don't have to do next time there a minor update.. or can i skip wipe cache?, or skip flashing gapps (unless there's a newer version of gapps)?
thanks for any answers

but i still wonder if it's needed to wipe cache/dalvik because it seems to remove some login info fx. in gmail, wallpaper and such, and if it's not needed, then i might as well not do that

If you dont wipe them, it can cause troubles.
Also, it shouldnt affect anything, doesnt for me
Edit: Gapps must be flashed everytime for PA. Forgot to mention that

Found this thread by searching.
I have a question. When you upgrade the ROM, and do all the steps listed above, does this also save the installed apps on the device?

Yes. Flashing the rom, then gapps, wiping cache and dalvik doesnt wipe any apps or apps data

4.3 flashing and bootlooping problem

Hi there
I seem to have a problem flashing 4.3 roms, actually any rom that isn't stock in general.
Right now I am running syzmel's 20E with 1.3ghz overclock version 3.09.
Back to the problem: this is the steps I take to upgrade to any rom: 1. Download (slimbean, vanir asop) 2. flash v20D (unmodded) 3. Root it using Framaroot 4. Install CWM using L7CWM.zip (extracted, then clicked on flash bootloader, flash recovery, and then booted into recovery) 5. Boot into CWM 6. Click on factory reset and reset 7. Go into mounts and storage and format /system 8. Go to advanced and wipe dalvik cache. 9. Flash either 4.3 version slimbean or Vanir ASOP (tell me which is better) 9. Flash gapps (Slimbean: Slim AIO minimal Gapps, Vanir: 4.3 minimal Gapps which is found in the Vanir ASOP page) 10. Factory reset again 11. Wipe dalvik 12. Reboot
Now as soon as I reboot, either it stays rebooting, or boots once and when you reboot it stays at the boot loading page (slimbean logo, or android logo) (In other words, once you go black, you never go back. Not being racist, just saying once it blacks out it doesn't work no more). So i retry. And then I give up and stick on v20E.
So please suggestions?

Are you sure it wipes made ​​correctly?

Danm, yes I'm sure.

Why you dont format cache and data & data/media ?
Did you try boot without gapps... Sometimes bad gapps cause a lot of problems
Sent from my LG-E610 using Tapatalk

When you factory reset it clears cache automatically. I'll try without Gapps.

wipe data,wipe cache wipe dalvic cache

How do you factory reset? Factory Reset is NOT only wipe data

Factory reset in CWM clears cache automatically.
....Anyway, I finally fixed it. Turns out I had to wipe EVERYTHING. Including /data and /data media. Thanks anyway guys.

[Q] How do I flash from L To a custom AOSP KITKAT

How do I flash from L To a custom AOSP KITKAT？ Do I need to flash the factory image at first or I just boot into recvoery and flash the cutom rom?Did anybody know? THX!

To be safe, you'd do a factory image flash. That way you know you have a good starting point. There's the boot image, including the ramdisk, and radio (depending on what platform you're running on) that would have changed.
Or, if you're feeling lucky, clean wipe and flash your new ROM. What's the worse case scenario? You have to do it twice.

The safest way is
Download L port
factory reset once
wipe cache dalvik
flash ROM
wipe cache and dalvik again
reboot
done,
Gapps included.
I never got problem with these steps.

Hey,guys,I have just ask the L's developer ,he said that the L he developed uses the same baseband and bootloader as the Kitkat,so there is no need to flash a factory image at first , instead ,we can just directly flash the Kitkat aosp ,Thanks for his kindness!

That's what he meant. Format system and data. You'll find that option on the custom recovery.

You just need to get a flashable one and your good to go. Just wipe system, data and caches and flash it. I tried both ways by recovery and by script and its the same experience. But if you follow the script and flash through PC you'll surely lose all your data.
