[Q] Full wiping and residue files - Samsung Galaxy Nexus

This is a question that has been bugging me for some time since my technical knowledge on Android doesn't go that deep.
Whenever we do a factory reset with either TWRP or CMW recovery to change from one ROM to another, does that action delete EVERYTHING from the previous ROM, or are there some residue files left?
Every now and then, whenever I see that my device feels slow or having lots of small issues, I flash the stock Google factory image, which deletes pretty much everything extra, and start again from there.
Do any of you do this aswell once in a while? Or is it useless?
Any other tips to help my little bit of OCD regarding a clean file library?
Thanks!

No a factory reset doesnt wipe anything. In fact it only wipes your data (your apps and any app data). So if you want to start clean you must wipe: factory, cach, system, dalvik cache.

[Q] Synergy ROM issues

Posting here since I cannot yet post to the actual ROM forum.
I'm running the Synergy ROM, RC1 and have a couple of issues. First though, thanks to the DEVs for all of their time and efforts, this looks to be a very good ROM!
I've been through most of the 200+ pages on the ROM's thread and did not see any information that may help (except turning off auto rotate of the home screen), but it's possible I missed.
The main issues I have are slow response issues. They are:
Slow response when I pull down the navigation bar.
Slow response when hitting one of the soft buttons (i.e., the + button to launch the app specified by the settings in Rosie).
Very slow response when I come out of a game that was in landscape mode. It takes a couple of seconds for the screen to switch from landscape back to portrait (after flipping the phone to portrait) and then another few seconds for it to put all the icons back on the home screen (home screen is blank when I come out of the game). I did turn auto rotate off and that has helped, but was wondering why there was such slow response without it.
Google apps such as Maps and Calendar that are started by another application, but do not shut down the starting app exists. This, of course, drains the battery and was not an issue on the stock rom.
When I flashed the rom, I did do a factory reset and erased all other caches. My apps and app data (not system data) were restored via TB.
I have also frozen the following apps via TB:
Flash
All live wall paper apps
Stocks
Flickr
FM Radio
News
Stocks
Smoke & Visualization Wallpapers
Voice Dialer
Voice Search
Thanks!

When you flash a new rom, only restore Apps using titanium backup, restoring data too will cause problems.

Absolutely correct. On top of this, the other reason you may be seeing slow response would be the fact that this is a very large rom, and takes up more space in your usable memory than most roms. What I have done to *somewhat* alleviate this issue when I'm running the synergy rom is to move all of the apps that I can (except for those that I use widgets from) to the SD card.
Just my recommendation

My thought was that when restoring an app, such as WSOP Texas Hold'em, I also wanted to restore the data so it restored games won, amount of money, etc.
Is that data what you are saying I should lose when flashing new roms?
Thanks,
Mike

Quite a few of my apps are on the SD card. I have 313MB free on the internal storage. Should that be enough to reduce some of the lag.
Thanks!
HELP!!! I flashed synergy rom last night and today, it goes to the boot animation screen and freezes. It just shows the synergy rom bouncing around and wont go anywhere from there. I tried doing a recovery through bootloader, but it wont let me move down from fastboot. Did I just brick my phone or is there any other way to get past this screen? can i plug my sdcard into the computer and delete this boot animation and if so, where would I find it? Please help, it would be GREATLY appreciated!!!
Give the phone a minute. It will let you move it. I just keep hitting volume down. It will work.

If you can boot into recovery, you did not brick your phone.
I've had this problem before and I don't even use Titanium. I also had plenty of free space on internal. Ram never seems to free up though. It's the strangest thing.

Does anyone else have issues with anything that requires data syncing (Facebook, Twitter, SMS, etc) stopping unexpectedly? It seems to happen at around 30% battery and the only way I've consistantly stopped the problem is to wipe and reflash Synergy Rom.
Any ideas?
Yea Idk what's going on with it after about an hour I would get android.process has stopped and needs to force close. I can't even use any app as that constantly pops up. Great ROM but unusable at this point.
Did you do a complete wipe before you installed it. Most of the issues I have seen arise because a complete wipe has not been performed. If you like the rom, do a complete wipe (factory, partition and dalvik) and reflash it.

This is after a full wipe, twice. Once the battery gets to a certain point, everything starts crashing and never recovers no matter what I do. Battery pull, full charge, cold restart. Nothing works.
Edit: I've also noticed that the GPS is locked on and I cannot shut it off.

Yea I also did a full wipe two different times. I didn't notice it happening once the battery gets to a point I just know that after an hour or so of use it was unusable.
1. If you use DualRomX2 would that possibly speed it up? Because doesnt it install Roms on EMMC?
2. Im also really frustrated by the slow response on alot of things like right rosie button and notification pulldown.
3. Video recording for me is just awful. Im not sure about actual quality but the framerate for sure is horrible. I compared a video i shot on stock and with Synergy and there is a HUGE difference. Synergy video being much worse.
Great Rom just plenty of little annoyances.
Synergy ROM loading issue
Flashed Synergy ROM last week and was very impressed. However, saw where 3.0 Sense items were missing and realized after reading several other posts that the carousel +widgets.zip should have been loaded with the ROM. So I reloaded the ROM and widgets through AMON-RA Recovery (Followed all of the original instructions I had followed the first time I loaded the ROM). Everything looked fine until I rebooted the system. Now Synergy ROM start-up screen loops over and over. At this rate the fill battery I started with will run out, and I'm not sure what will happen at that point.
Anyone have any suggestions for this issue? Any help would be appreciated. Thanks.
Options:
a) Pull your battery, boot into recovery, format data/wipe cache/dalvik cache/format boot/format system, & flash a different rom.
b) Pull your battery, boot into recovery, format data/wipe cache/dalvik cache/format boot/format system, flash Synergy again, reboot.
c) Pull your battery then turn on your phone like normal.
d) Pull your battery then boot into recovery, wipe cache/wipe dalvik cache, then boot into rom.
Edit: I don't use Amon_Ra, when I refer to "recovery" I was referring to CWM. Hopefully someone with experience comments in regards to Amon_Ra recovery.
Yeah I don't have too many issues with it... last night it got kinda squirrely so I fixed permissions in recovery and re-flashed the Warm Theme without wiping any data, it's been all good ever since.
The ROM is my daily driver... I really do think that these issues are app-related. There is something that certain apps do that this ROM is not built for, I'm just not sure what it is. It's been real good to me overall though, battery life and all.

SlimSnoopOS, as it turned out I pulled the battery and rebooted into Recovery after a few hours, but thanks for the direction. These were the exact things I did. The reason I used AMON-RA instead of CWM is that Synergy says in a number of places that it only loads with AMON-Ra (and I'm a coward!),
Awesome, glad everything is functional again!

CyanogenMod 9 Alpha 1

HI all,
I've flashed CWM5.5 from the recomended thread and installed Cyanogen 9 Alpha 1. Unfortunatly the phone seems to boot up but does never leave the boot animation screen (yes I've also flashed gapps after cyanogen).
Anyone can identify this pattern? On a normal device I could hook it up through a serial cable and try to debug the boot... Eventually how can I do that with a I8150?
Well, any help would be most welcome. I'm totally available for testing and I do have some experience with Linux even at a very low level/system space.
Install
Use CWM5.
Warning: Only use this recovery to flash CM9. Otherwise, you risk bricking your phone!
Wipe data and cache.
Flash update*.zip.
Flash gapps*.zip. You must flash gapps after every upgrade to CM9 since /system is formatted, wiping your previous add-ons.
Reboot phone.
After you setup your Google account, reinstall the three apps from Market in order to restore most of your apps, call log and SMS history.
Warning: Do not restore backup data of system apps!
If you restore a bad backup with cached settings in telephony.db in data/data/com.*.*.telephony it can break MMS.
It seems that restoring backups can also break Calendar sync.
read it thoroughly ...
1st you must flash update*.zip
2nd gapps*.zip
that just about it ....
what is your current kernel ?
That was pretty much it... I've restored not the original operator crap ROM, but instead the Value Pack ROM.
CyanogenMod9 seemed to install ok, but just looped and the phone didn't finished the boot. I'm not really sure on what happened. I'm just finishing restoring the stuff
I'm guessing you didn't wipe data/cache.
I did a factory reset, but sure, it might not have wiped the whole thing... Going to try again.
@argo68
True mate, the issue was not wiping the user cache. I've wiped the cache now from ClockWorkMod and it worked ok. Takes some time to boot compared to the stock samsung ROMs but it works fine
Anything you need tested ? I can most likely help.
I do have a problem with apps though, for example, GMAIL doesn't show the body of the message... as you can see on the screenshot, but I guess this is a app related issue maybe?
http://susepaste.org/images/39081870.png
After a reboot somehow it boots a bit faster and the gmail app is now displaying the body of the email and it seems a bit faster...
Good work, gonna ride this for a few days and see what happens.
@argo68
If you need beta testers, let me know. I'm off work this days but can't wait to get into my lab and check this stuff deeper

Hi I'm using this cyanogen mod for quite a few days now. The back side of the phone is always warm and the battery is drained very fast. Anyone have this similar problem?
I'm sure that I install the ROM correctly as i cleared everything on the phone with CWM 5.0.0.4 before and after. (Phone data / Cache Partition / Dalvik Cache / Battery Cache)
Any help would be appretiated
No such problem here. You should use an app to check what frequency the phone is running at in idle, and also how much load there is on the cpu.

[Q] Factory Reset

So I just ordered a nexus tab off out of the play store, and will be giving may A100 to the wife and kid. I am currently unlocked/rooted/CWM, and running an old version of flexreaper "R3.1". I also have crossix memory swap mod as well.
I hope to revert the thing back to the stock Acer setup, and get it back on the OTA's and whatnot. Is there a safe way to go back. I have seen alot of threads about people bricking their tabs trying to do so, but no threads about a succsessfull method.
If that just isn't a good idea, the tab runs great as is. Is there a safe way to run the "factory data reset" and get my wifes google account set up as the primary, and me off of it?
Anything I need to worry about like
recovery files
boot images
etc
that need to be gone before I do the factory reset?
Thanks guys.

Restoring to stock I'm not sure about but here's the run down for resetting:
Reboot into recovery
Wipe cache
Wipe dalvik
Wipe data
Wipe system
Flash your FR again
Reboot
Wait 10 minutes, reboot
Setup with new account info and rock on.
Its a bit excessive but its the best way to reset without leaving anything behind. No need to worry about any images or anything like that unless you plan to install a different recovery.

That formats where settings and apps are installed, but not internal SD, so keep that in mind. But yes, a factory reset will just put it back to the beginning. Also, consider this: its just a simple format, anyone can still pull whatever data was there back out of it. It's not even hard, just takes some time.
You could also use Pio's Black hole script.

Well they don't seem to want to much past minimum to reset it otherwise I'd say system nullify before selling. Not a speck of data left behind /shrug
Edit that sounded a little harsher then I intended. I think its more to do with not being rooted so they can only simple reset.

Hyperdrive Rom Crash Help

Sorry if im a total noob at posting but spare me, when I have a chance ill change the specifics and have it in the appropriate forum but at the moment let me describe the issue at hand. Im currently using hyperdrive on my sprint galaxy s3 and at least more than 8 times a day I open a simple app or attempt to multitask. The phone freezes and I have to keep rebooting and rebooting until it finally works. Has anyone other than me had this issue?

Switch ROMs.
Maybe your phone just doesn't play nice with the Hyperdrive ROM. Try out a new one, or do a clean install of it and see if that fixes it!
Switch ROMs?
Well, I suppose it's a fix.
The thing is, what if you want Hyperdrive to work?
I have been getting random reboots, which led to boot looping. I have done a clean re-install, but mysteriously lost the multi-view launcher.
Any ideas? Besides switching ROMS...

The difficult thing when trying to troubleshoot Roms like Hyperdrive is that unless you document exactly what option you chose (which kernel, mod, theme, etc) in the Aroma installer, it'll be difficult to replicate your specific situation. Do you happen to know which settings you chose (maybe walk us through page-by-page in Aroma). Than we'd be able to help troubleshoot what's going on in your phone.
That being said, I'll walk you through some generic fixes for reboots/bootloops. You can try each one in order, and if #1 doesn't work, try #2, so on and so forth. They may work, but no guarantee.
Clear Cache & Dalvik Cache: This probably won't help, but there's a long shot that it would.
Fix permissions in TWRP or CWM: If it's a system app that somehow got installed incorrectly, this will help fix that issue.
Reinstall the Rom with a "so fresh and so clean clean" wipe: Wipe Cache, Dalvik Cache, /data, and /system. Make sure your rom zip file is in an accessible location, because wiping system erases your system (you won't be able to boot).
Reinstall the Rom without any mods: If you really want to take the time to flash the Rom multiple times, I'd say flash the Rom without any major mods. If nothing is broken, you can reinstall it again (after a so-fresh-and-so-clean-clean wipe) with another mod installed. It might takes hours, but if there's something inherently broken in the ROM, you'd be able to find the culprit if you do it this way.
Do not restore apps/data from TiBu: A lot of people have had issues because they've restored system apps/data through Titanium backup (TiBu). I still use TiBu for a lot of my backup needs, but I never restore system apps with it.
That's all I really got in terms of fixing the problem. I hope you can get your phone working the way you like.

[Q] Question about wiping data with TWRP.

I'm flashing my phone with a new ROM, and I'd love to clean my phone out completely. I noticed when I did the standard wipe data/cache/dalvik, I'm still left with all of the other junk from my previous install (draw something, photos, etc.). How do I go about cleaning out my phone without screwing anything up? I've been Google searching what the exact steps to do so are, but all I can find is people wondering how to fix the screw ups I'm trying to avoid.
I'm using TWRP v2.6.3.0.
Thanks.
edit: Apparently I can't English at 4am.
Bump. Anyone? I figured this would be a simple one for most of you guys.

I will format data also. This gets rid of the extra files from previous downloads that is not always cleaned by factory reset.

I'm assuming that you've also been doing factory resets?
If you have and that's still not getting rid of enough for you, there's an option in TWRP to wipe your storage (see the last paragraph in particular: http://teamw.in/whattowipe) and get rid of everything, though I've never done it myself. You'd obviously have to be careful about having your nandroids, backups, and the ROM you want to flash somewhere else ready to go after you've wiped.
I'd wait for confirmation from someone who's done it before giving it a go, mind you.
I assume that the storage wipe won't affect my SD card? That's where I have the ROM, etc. That's all I'm concerned about.
My options when I go into the "Wipe" menu are Advanced Wipe, which gives me the options to wipe Dalvik, Cache, System, Data, Internal, External, and USB-OTG.
The other option is "Format Data", and that says it'll wipe my apps, backups, pictures, videos, media, and removes encryption on internal storage.
I assume I need to do the "Format Data" one, but I'm just wondering if that will affect any of the important stuff in the phone, ie. recovery and whatnot.
Okay guys, thanks for the help. I just went into the "Advanced Wipe" menu, and wiped Internal Storage, as well as the standard dalvik, cache, etc. Seems to have done the job, my phone now has 10GB free with a new ROM, as opposed to 3GB free. I figured I'd post my results, just in case someone else wanders over here with the same question.
Thanks again.
