Wiping data after flashing - Galaxy S II Q&A, Help & Troubleshooting

I have flashed official roms several times, but only wiped data once because of a bootloop when I went back to an older firmware. The firmwares have always worked fine for me, I did have to clear data on some apps usually, but generally everything seemed to work fine.
I was wondering if most people on this forum wipe their data and use something like titanium backup to both back up and restore their data. I am mainly concerned about games, the rest of my data is easy to set up if I lose it all. The dilemma I have here is if I should root or not. I have heard that once you flash you cannot receive updates via KIES or OTA so I am stuck flashing which isn't a big deal, but I never intended to root.
I would really like to be able to just flash, clear data on some apps, and have everything work fine. Will this work every time? Or is that hard to predict? I also want to know if there is a non-root method to save game saves to an sd card or back them up using some other method.
Anyway, I am interested in everyone's thoughts.

What are you trying to say? !
You talking about flashing official firmwares? or custom roms?
Root is required for titanium backup to work.
If you're flashing any official firmware you still can receive kies updates.
Get root! It's nice to be a superuser and enjoy the sheer possibilities that our gs2 offers.

Official roms
I usually don't wipe my data and it works well, and I have never rooted. I am just wondering what everyone else does here.

Flash to Stock Bell and lost Google Apps

ok, so I flashed back to stock bell ROM via the instructions from NFHimself.
Everything worked fine, my phone is now back running fine, and i was able to run the Bell OTA update.
Only problem is now somehow i've lost all of the Google apps (ie. Maps, Gmail, Market).
Without the market I haven't been able to restore any of my apps. I've seen a lot of Market.apks out there, but theres dozens of versions, and i don't know if any of those are legit anyways.
Help?
factory reset, will come back.
I had the exact same problem, and the factory data reset fixed it.
thanks mates.
seemed like a pretty easy fix. i guess i didn't think of it since i figured it was already a clean flash.
cheers

My Note is very unstable - can't tell if it's a lemon or something I did

This phone was an insurance replacement from ATT, so alway a bit wary of these refurbished phones.
So for the longest time it has always been a bit glitchy, hanging, and unstable. I assumed it was a software problem, and something i had done wrong when flashing...but now I am wondering if maybe my phone is a lemon. Lately it has been rebooting randomly on its own,
I wanted to try flashing back to stock, just to start from scratch, and I did with Da G's stock rom . Then i just rooted it with Da G's root, and put on CWR. Then I flashed King Kang Rom. It's been still real buggy. Maybe I need to to stock ICS or JB then flash a ROM? OR maybe it's just this phone....either way not real happy with the stability i've been dealing with.
If youve tried multiple roms and stock roms and its still buggy then its probably the phone, I have got so many replacement phones that were duds
Are you doing a wipe between all those roms or just flashing one over the other? That could be a major problem that is easily fixed.
Yes, i do full wipes/factory reset in CWM every time.
I know i have seen some guys say you must flash like 3 times, so maybe i'm not flashing it enough times or something..? i also saw someone say don't touch your phone for 15 minutes after flashing. i have no idea if these tricks actually work or what. doesn't seem to be a definitive rule book on how to flash the right way
How are you restoring your apps? TB or letting Play reinstall them?
using TB. I usually do a just apps reinstall, then data
Was the TB backup from a different version of android, i.e. GB, ICS then installed on JB?
yes, i did create it on an ICS rom. you think that could be causing me problems?
Good possibility. I had the same issue. Moved from CM9 to CM10 and restored through TB. Lots of FC and reboots. Wiped and let Play reinstall everything, now its smooth.
great thought and worth a shot if that's what could be causing a problem. so did you lose all your data then with all apps? msgs, etc? sucks to start from complete scratch. i'll even miss call log
Lost data, but was able to d/l everything else. Messages and call logs were gone. It is worth it to have a working phone with out glitches. Let me know if it works.
Well a good test is to install a known solid ics problem free ROM like Padawan or Black ice? (exact name escapes me). If it works for u then over clock it to 1836 with setcpu and u will have a ROM VERY close to the JB rom smoothness but actually works.
If u still have problems then u may very well have a flaky phone.
(Oh yeah don't get to worried about stuff like wipe 3 times etc...old wifes tales. I haven't done that for over a year on 3 android phones. ). Also it is Safe to restore apps AND data with titaniumb (just not system data).

+1 on the old wives tale. Seems more like a placebo effect. I only wipe once, and I've flashed roms on tons of phones.
Sent from my Galaxy Nexus using xda premium
tried installing padawan...so far so good, have not overclocked yet....will report back
Some roms will format your system partition prior to flashing the rom while others do not.
Beyond the wipe of data, cache, dalvik and such, it is wise to go into " mounts and storage" and format the system partition while in CWM recovery.
This ensures that nothing remains on the device before the new rom image is pushed to the system partition.
I agree that wiping 3 times is a bit over the top, but wiping the entire image base before flashing a new one is almost always mandatory.....g
For future reference, you can back up call and sms logs and restore them without causing lags or fc. The logs are simple .xml files.

[Q] hard factory reset with safestrap/rooted phone

Hey all,
I have a Razr Maxx (well until a few months from now when i can get a better phone).
It is rooted. and has SafeStrap (I used to use the other slots to try some 4.1.2 and 4.3 roms but they all had issues with the radio signal so just been using Stock rooted rom), and VooDoo OTA rootkeeper (Verizon updated my phone OTA the other day, VooDoo seemed to work yay.... still was at 4.1.2, think it was only a security update heh).
Anyway, I'd like to do a Factory Reset since the stock rom, after installing all the apps I thought I wanted, becomes so slow.
Curious if I can do it via SafeStrap->Wipe->Advanced Wipe for the Stock Rom Slot .... or should I do any safety things like remove SafeStrap or TempUnroot it via VooDoo then do it via the phone way of doing it (by pressing some buttons at once). I'd like to still keep root. Wasnt sure what best procedure is.
Probably will just have Google Maps and Spotify on there (Titanium Backup, VooDoo, and a few others) and never install the 100 'used only once/twice a year' apps on there currently.
Thanks for any advice,
Ari
Rant: My phone seems to always get so slow once install the cool apps I want... and I've tried all the cache-clearing solutions on the stock rom but never works. (not sure why, me and all my android friends seem to have these issues once install apps. None of these apps seem to be doing anything on boot/startup based on Memory/TaskKiller apps I use to look at current apps, so not sure what slows the phone down).

Yeh it did work out. I think I just the regular button? combo to do a Hard Factory Reset.
I may have done the VooDoo Unroot and re-added it back in via VooDoo...
that or I may have had to re-root the phone though (think latter is what i did).
Either way I got root back.
The annoying thing is Verizon or Google? backed up which programs I had installed and it just reinstalled all of them immediately after a factory reset.... so it became mostly unusable again. Tried a few programs to figure out if its CPU or Memory and cant figure out why still slow.

so you would advise against
SafeStrap->Wipe->Advanced Wipe for the Stock Rom Slot.
the reason why im asking is because I cant seem to load back into my stock rom, and i carelessly did not make a backup. I was thinking maybe a factory wipe on the stock would help.

When you try other rom you must download the cdma if u are in USA...the gsm don't work
for the stock slow rom try greenify https://play.google.com/store/apps/details?id=com.oasisfeng.greenify&hl=it
and clean master https://play.google.com/store/apps/details?id=com.cleanmaster.mguard&hl=it
and when you do a factory reset and set google account uncheck backup or when play store start download,go in my app and stop the all the download

[Q] No mobile network after flashing roms

Would like some help. I have flashed CM 11 and can't make calls. It says mobile network not available. Tried flashing AOKP rom as well and same thing. Mobile data works fine, although i have gotten a popup twice that says 'Google Play Services not supported by your device, please contact your manufacturer' (no noticible issues from this, google stuff i've tried so far works). I have included a screenshot so you can see my baseband and rom version, etc.
Now, i had a great deal of trouble getting a rom flashed to start with, CWM put me into a bootloop and TWRP wouldn't flash anything because it said it couldn't mount /storage when i tried. Used Philz advanced CWM (love it btw, will be using it from now on). Still wouldnt flash the hltespr specific CM11 version so had to use the unified hlte version (it gave me the status 7 asserts issue, but editing the asserts out just gave me a bad file error when flashing). I wiped data/cache/dalvik between each flashing. I don't know if any of that would have bearing on this problem, just including any details i can. Any advice?

Have you upgraded your bootloader to NH7? I know most of the newly-updated CM-based ROMs require you to be on NH7 before flashing. That's most-likely why you weren't able to flash the htlespr ROMs. The unified ROMs no longer include the correct APNs for Sprint, so that's why you don't get service on it. I don't know why mobile data works on it.

No, didnt realize that i needed to do that. I'll do some research on it because i don't have any idea how to update the bootloader. If you have a link to a good tutorial that would be wonderful! Thanks!
Ok so i tried that, found this tutorial, followed it, no luck. Tried full wipe/reset after that to see if it would let me install the hltespr versions, still no dice. Same situation, mobile data works, calls don't. Will have to wait till daylight to try texting so i don't wake anyone up but i suspect that texting won't work either. Has anyone experienced this and fixed it? Lol i really didn't drop $100 on a phone to be saddled with all the Samsung and Sprint baloney that it comes with, don't wanna unroot....
Bump
Anyone have ideas on this? Have continued to try fooling around with the udater-script file to resolve the status 7 problem so I can install the hltespr variant, still no dice. Please someone help!
Bump!
Sorry, I typically don't have access to XDA forums on the weekend, so couldn't answer your question till now.
You flashed only the baseband/modem, not the Bootloader. If you want to update the Bootloader, you need to use ODIN to flash the Complete OTA NH7 Update.
In order to update the Bootloader, you need to make sure that you use the PC ODIN (not the mobile one) and that you completely power off the phone before you enter download mode (don't access download mode by using the extended power menu when shutting down the phone). I don't think you need to do the battery pull that Freeza had in his instructions (I didn't do it when I ODIN-flashed the NH7 OTA update), but it wouldn't hurt to do it.
Thanks for that, I will try it as soon as I get home tonight! The next thing I had decided to try was to unroot, to back to stock, then try flashing that before I start with the custom recovery and ROM. Do you think I should do that first before doing the whole thing or could that work just flashing that with my phone as-is?

Well, I always recommend a full wipe (data, system, cache, dalvik) when flashing ROMs. I haven't wiped my internal storage or external storage since I got the phone, so that's not really necessary.
I don't think that unrooting your current ROM is necessary. Flashing the ODIN OTA update will automatically remove root access, so that's not an issue. Here's the steps I took when I updated to NH7 and installed my current ROM (see my sig):
Make a Nandroid backup.
I always do this just so I have a "record" of what I left behind. It also allows me to have all of my app data that I can restore via Titanium Backup (you have to buy the Pro version in order to restore specific apps from a Nandroid backup). I always store a copy on my ext. storage and on dropbox.
Do a full wipe
As I mentioned above, I always wipe data, system, and the caches when flashing ROMs. While I have to take some time to get the new ROM exactly as I like it, it minimizes any potential FCs and errors that some people get when dirty flashing.
Install NH7 all-in-one via ODIN
I installed the NH7 via ODIN. Please note that this is the fully stock, unrooted ROM and will also install the stock recovery.
Let the phone boot and connect to Sprint. Update Profile and PRL.
I do this periodically whenever I go back to stock (from AOSP). I rarely have connection issues, but updating the PRL an profile can help with those.
Install a custom recovery using ODIN.
My recovery of choice is TWRP, but others have found just as much success with CWM and Philz. Just make sure that you're installing the correct version of the recovery (4.4.X version, not the 4.2.X version). I always reboot to the main system after installing a recovery, but that's up to you. In the rest of this post, I'll say "TWRP," but I really mean "custom recovery."
[OPTIONAL] Make a Nandroid backup of the stock ROM
I always do this, but I recognize that it's not necessary, especially since we can just ODIN back to this image at any time. I just like having the option of having a stock backup on the device (in case catastrophe strikes while I'm away from a computer).
Use TWRP to flash your AOSP ROM of choice.
If you haven't installed any apps or messed around with the settings, you shouldn't have to wipe before flashing, but (in case you haven't noticed by now), I tend to err on the side of caution, specifically: wiping everything (data, system, and the caches) before I flash anything.
Set up the ROM how you like it and [OPTIONAL] make one last Nandroid Backup
Whenever I set up a new ROM to the exact way I like it (statusbar settings, accounts set up, apps installed and configured, etc), I make a nandroid backup of my device. This allows me to go back to that "fresh" image whenever something happens to the device and I don't have to muddle around fixing those minor tweaks. Again, I tend to err on the side of wiping the phone too often and taking too many backups, but I've rarely had issues with my phone and ROMs because of it (to the point where I can spend most of my XDA time helping others with their phones), so it might be prudent to follow the advice.
Anyways, that's how I upgraded to NH7 and installed a custom ROM. Others may take a less conservative approach and you're welcome to adjust any of the optional steps.
Hope this helps!

OK, did all that successfully, when it went back to stock stiil had the same issue. Mobile data functions, mobile network for calls/SMS doesn't. Did the whole update prl/profile and even tried reactivating from settings, still nothing. Was able to install custom recovery (Philz) and the hltespr CM11 variant instead of the unified generic version. Still has the same problem, mobile network not available. Everything else works perfectly. I did verify in settings that it still wound up as the NH7 after everything I did. Note I did a full reset before each thing that got flashed in this process, and one more for good measure after. Let it boot to the system between steps too.
Lol I've been rooting and switching between ROMs for years and have never encountered anything like this. I'm stumped....

Dumb question but are you a Verizon customer or Sprint?

Sprint, I've had big red before but when they did away with unlimited data it wasn't worth paying their high rates.
Bump!
Anyone have any ideas on this? I am just confounded as to why this continues even after being reset to stock.
Same Issue!!!
I have the exact same issue and have been trying to resolve it for the last 2 days... Did you find a solution?
I have the same problem on a Samsung Mega. LTE and 3G data work but phone won't dial if LTE is active. It WILL voice dial if only 3G is active. Sprint. CM11.
I had this problem after flashing ROMs as well, but went into Settings>Connections>More Networks>Mobile Networks>Network Mode and selected LTE/CDMA....no network had been selected. That fixed me right up. Weird part is, I could still avcess the web without WiFi....but couldn't make calls or ise my bluetooth headset until I had performed the above steps. Hope that helps.
thanks forget the little things reset wifi and sprint cell extender

GAPPS Fail on Nandroid Recovery

I have been running various flavors of AOKP ROM's on SG3's for several years now. I recently obtained a refurb S3 and set it up to do the usual.
It came with stock TW 4.4.
Using ROM Manager I installed CWM and made an image of the stock phone. I then installed my AOKP variant and loaded my apps, blah blah. All is good.
I've since decided I want to revert back to TW for awhile. I restored my nandroid and I get the interminable GAPPS failure messages. I have on occasion been able to get it to calm down and have a working phone, usually be uninstalling play app and clearing framework services cache. This is extraordinarily painful and doesn't always work. I've done all the usual, reinstall GAPPS, etc., and basically it is a MAJOR headache just trying to get the image to function.
But....When it does work the phone does not see my SIM card, IMEI, nothing.. I have no mobile connectivity. Restoring the AOKP nandroid brings me back to a fully functioning phone.
So my questions are:
Can anyone explain to me why the TW nandroid is giving all these GAPPS issues and how to circumvent/fix it?
Why is the system seeming to lose my IMEI/SIM info? Is there a way to fix that? Should I have done something different in my setup/nandroid creation?
Lastly - I don't quite understand how CWM works. There is a recovery image. When I do factory reset, is it resetting to this recovery image as opposed to the factory TW? I seem to think so, when I do a reset I see the android version is not what my factory one is.
Thanks all.
