Question about the internal storage and ROM flashing - Nexus 7 Q&A, Help & Troubleshooting

Hey guys, long time rooted/android user here, I am about to get my Nexus 7 on Monday, and I just had a couple of questions. First, since there is no external storage, when you wipe the device to flash different ROMS, does it wipe EVERYTHING? Like, say I have 250mb's of downloaded data for a game...idk say, Dungeon Defenders, I know that when you typically wipe a device, it wipes everything, but will it still wipe that data? Basically, what I am trying to say is, after each wipe/install, will I have to redownload all of that extra data from the game again? That seems like a super big pain in the ass. Hopefully that isn't the case because I don't want to spend 3 hours redownloading data for games after each new flash lol

No. When you unlock for the first time, it cleans out everything... so do that asap before getting cozy.
CWM is designed to leave your storage folder alone. So wiping and flashing won't touch anything saved.

Sweet! Thanks for the info. The first thing I do when I get a new android device is root it haha. I have heard that you shouldn't use the toolkit with the device though, is that true?

No, at leat in cwm, it wipes everything not in the sdcard partition, so if you keep any nandroids, or app data in that partition, you'll be fine

The toolkits work fine most of the time. Its just always good to learn how to do things through commands in case the toolkits, or anything regarding your nexus has an issue

Yeah I understand. I know my way around ADB so honestly for me, it is whatever way is fastest and gives me the least heartburn. I have heard that users start to have issues after the first day with the device, so I will hold off for a day before I root it, just to be sure

Factory Resetting bad??

I factory reset my phone alot, im talking maybe once a week. Is it bad to do this?? Will my phones performance plummet or what? Thanks in advance! =]

I wouldnt think so the flashaholics and devs flash more than once in a day sometimes, when i was trying different things with Supreme, i would format system/data/cache and wipe dalvik sometimes 3 times a day and reflash because i had an error
Sent from my PG06100 using Tapatalk
its perfectly fine, i do it all the time testing different things on my transform and ive never had a problem from factory resetting it. hoping to be able to be a flashaholic again soon with the shift
I suppose it could over the long run. I think it would take quite a while. Because I've been doing full wipes, and factory resets. Testing stuff, reflashing because of errors, or just dev stuff. For a while now, zero adverse effects.
There have been debates about this in every forum on XDA I'm pretty sure haha. The general consensus from what I've read is this. NAND memory does have a lifespan, that much is a fact. It is most people's opinion, however, that even above average flashaholics will not reach this lifespan in the couple of years they have their phone.
Not as bad as dropping your phone.

That can be pretty bad, yes . What precisely do each of the various wipe/resets accomplish? I.e., factory, dalek, memory cache, partition reset, etc.

Factory wipes you /data and /cache which data is where your apps and random user stuff is stored, your cache is your cache... Your dalvik from what I understand is what makes android android, that's where all your widgets and what not reside, /system wipes your system files and formats it, of you wipe that you need to flash another rom cuz your phone won't boot other wise... If i have anything wrong please correct me, but ya

Why I'm hesitating to root...

Hi Folks,
My first post on N4 section.
Ive just upgraded from a HTC Sensation that I've been running for two years, mostly using CM9 & CM10 on it, so Im well aware of all the benefits to root.
Even been lucky enough to have some of the excellent Devs cooking in this section over at Sensation workbench too, like Showp's kernel with Sweep2wake.
So far, my Nexus has not been rooted, and although I miss custom Rom-ing, im very excited to say that not rooting means that some apps like SkyGo and Barclays Mobile banking & Barclays PingIt are working very nicely for me indeed, something that never happened on my Sensation.
Since my go-to rom on Sensation was AOSP anyway, Im pleased with my stock Android for now, and it just seems that some of the apps I can use now are pushing me into the non-root territory.... for now.
Anyone with any thoughts on my current predicament?
I don't see anything wrong with it although you are going to lose data the moment you decide to root. Unlocking the bootloader would wipe data off your phone if I remember correctly. (Nexus noob as I came from Desire.)
via xda app
Agreed, I rooted my xperia, HTC evo and HP touchpad just to run AOSP. My nexus is staying stock for a long time, like you its very convenient to use the Barclays apps, only thing that might tempt me to root is to block ads....
Sent from my Nexus 4 using Tapatalk 2
I was in your boat with my HTC vivid. That thing had to be rooted to make it actually useful. But with the N4, I have no need to root. Ironic, don't you think? We finally get the phone that screams to mod it with how easy it is to root and yet we don't...

While I respect all of your decisions to hold off on rooting, I will recommend that even if you don't root, unlock your boot loader ASAP because as mentioned above, your data IS wiped when you do so and it is necessary to do so if you ever decide to root in the future.

I have taken a look at the nexus 4 toolkit by mskip and you backup apps and data before unlocking then restore.... So I don't think it really matters.

Hmm I didn't lose data when I rooted..
Also without root you can't make the most of your battery with under clicking, screen off profiles, cpu sleeper, etc.

As soon as I unlock the bootloader, my data is wiped. Maybe you used toolkits and such like what the other guy said and had that option to save stuff. As for me I prefer command lines as much as possible.
via xda app
I'm in the same place as you. One of my main reasons for using custom ROMs was because I loved the look of AOSP. Now I have AOSP, I'm less tempted to flash anything or root, because everything works and looks good.

Guide stickied in this forum has a how-to on ADB Backups.
Perform the backup as outlined and unlock...
Restore as outlined and it's as though nothing ever happened...all data restored.
Well, had the Evo V before this and I rooted/modded it to look/run like this phone runs out of the box so I don't plan on rooting at all.

Will unlocking Bootloader mean apps that don't work on Root phones stop functioning?
No unlocked DOES NOT equal root

to root or not to root

GF bought me a N7 for xmas (love abbreviations) and it was to upgrade from a kindle fire from previous.
I of course rooted the KF in about 5 minutes and its been running full android since first boot but with my N7 I almost feel I dont have to root for some reason. My NS phone is of course rooted but after setting up the N7 its almost so functional after that it seems to much work since rooting will wipe the device.
Anyway if you guys were in my position would you root or no?
If you need/use apps, that need root, yes you should ^^ if not, IMHO you don't need to, for me and my use (gaming, chatting, browsing, celebrating, xdaing) stock is very comfortable and nice.
It really depends on how you want to use it ^^ test stock for a few days and decide after testing

I didn't due to not having my laptop at time of purchase. While all is well and I don't need root for anything I have been thinking about rooting just because its a nexus and knowing I haven't modded it in the least is starting to semi bother me. However now I only have 8GB free on a 32GB version and really don't want to lose all my data. So I'd recommend it so you don't regret not doing it down the road.

I don't think rooting will wipe SD. It will wipe os. I just went to install button savior and saw it needed too so I'm pretty much decided. I turned on backup through google so hopefully when i root i can just use Google to restore my data for me and just use apex to restore may desktop

I would at least unlock the bootloader since it will wipe your tab completely. Then later on if you want to root you won't need to unlock it.

I got mine for christmas too. Rooted it on the same evening and it's a total different experience. Try flashing Paranoid Android and use Action Launcher. It's the ultimate tablet experience for me because both ROM and Launcher use the 7" display the best.
I root because I know I'm going to need root apps even if I don't feel like using a custom ROM.
Sent from my Nexus 7 using XDA Premium HD app
I really think there is no reason to root. Stock on the n7 is flawless IMO. I rooted mine just to familiarize myself with the manual process but I have no intention of changing anything. I even got rid of custom recovery and re locked my bootloader.

Your right, I just mean in my case since I didn't unlock bootloader or anything in order to obtain root I would lose all my data. But actually just the rooting part shouldn't wipe anything.

If this project was so important to you why didn't you back it up off of the phone somewhere? Dropbox or the free 50GB Box account most got with the Nexus 4 come to mind. I'm not sure if a full nandroid backup includes the contents of the sdcard on the nexus 4 but that might be a place to start looking, that is if you ever bothered to do a full backup of your phone.
You can get your files back, the same thing happened to me, my pocket somehow formatted my sdcard. Look for software that recovers deleted files

XDA also encourages users to search for answers before asking for help. This place is for learning new things and expanding current knowledge. People won't really learn if they're spoon fed what they want to know.

Boy do you have it wrong. XDA is not a place to come and get help. IT is not a support site. This is a developers site. You are EXPECTED to put in the time and effort to fix your own issues first. Then spend some time searching. (and do search outside your own devices forum) Then you try some things you have seen. If that doesnt work then you can post a thread but dont expect a solution.

So you mean the software like PC Inspector or Recuva or any other file recovering software will not work on our Nexus 4..??
once i deleted my photos from my old desire HD and i recovered it using PC inspector...now Nexus does not have SD card so i am not sure weather that will work or not..

I haven't tested such software, and I could be wrong, but when you connect (most) newer Android devices to a computer, you get access to the files via MTP. You don't have direct access to the filesystem (which I think is ext4), and because of this, you can't do the "advanced" stuff needed for file recovery (I guess checking sectors, free space, and etc.)
Older (and some newer) Android devices when hooked to a computer let you do USB Mass Storage (essentially the same kind of access you have when you plug a flash drive in), which is giving you direct access to the file system (FAT32), and in-theory, should work fine with file recovery software.
so can we mount the nexus 4 as fat32 or ext4? because on mine it just shows up in device section with no name

Backup via ADB?

Hey everyone
My Nexus 4 screen cracked, I'm sending it to LG for repair, they explained it will be factory wiped.
Before i send it, can someone explain to a n00b how I can back up my phone's data? I can't use the phone at all, the digitizer is cooked.
Thank you!

For the SD card, use adb pull. Your apps should be backed up with your Google account

Note that adb backup can be unreliable. I suggest making several types of backups--with APK, without APK, with system, without system, etc. Because you don't know which one will restore properly. Also do the more traditional backups, like SMS backup.

That's easy if they're in /sdcard/DCIM. ADB could theoretically back up your photos ("adb backup -shared"), but I wouldn't trust something so important to a tool that didn't appear quite reliable when I tested it.
