[Q] How can I prepare a Xoom for sale?

I have a Xoom 3g (USA) that I'm about to put on craigslist; anyone know how to reset it so that it's stock (no personal info). I know that there's files on there that are not deleted if you reset it, I'm looking for something that will reset ALL of the files back to stock (like you can do with an iPhone...).
***edit: Sorry, probably should have put this into Q+A... If an admin wants to do so, that would be OK...

Technically you should have put it lol..
but before you get flamed... this is how:

factory reset and hook it up to the computer then delete every folder/file off it.

I don't think I can delete "every file and folder" can I? Won't that mess up the Xoom?

Just reflash the stock images and erase userdata

no, you dont have access to files that are crucial to the xoom functioning correctly through the pc. If u dont want to mess with adb and img files then do my method. It's the same way like cellphones, you can delele everything off your sd card and the phone will still function.
I just checked nothing of importance is on the /sdcard folder so u can delete away. You don't have access to /sys or folders like that.

Yea thats another simple way to do it. Just remove all synced accounts and user installed apps, go into the sdcard folder and clean up the cache and program data folders there.

same question
I did all of the options available in recovery, and there is still data on the unit.
0/
legacy/
obb/
is my file structure.
I can't believe there's no way to wipe this thing (like new from the store) so I can pass it along.
Any ideas would be appreciated.
I'm good to use ADB or fastboot if needed.

actually, that doesn't do it. I bought a LTE xoom from a UK buyer who did that, and when I installed MXplayer, I was greeted with some lovely videos...
best thing to do to reset a xoom for resale is described in the link below:

this will completely reset the device to factory standards.

Thanks for link very good

Unlocking/relocking the bootloader should do it. You could do fastboot commands to wipe each partition I guess too.

[SOLVED] [Q] EDGE dissappeared. What could be wrong?

Hello. I have a strange problem. My device was originally on Orange but unlocked with xtc clip.
Then I've installed custom rom (Runnymede S V4.01) and everything was OK. But when i decided to change it to Affinity 1.48.0 I've got not working EDGE, only GPRS was working for me. In SETTINGS>About phone> Network Type is Unkwown (Ussually was EDGE). I tried all radios, flashing different roms. And I've mentioned that on MIUI ROM EDGE works correctly but when I install again Sense ROM it disappears. One more thing, that with other SIM Cards everything is OK only with my Current is the problem. I've tried to put it into another phone and EDGE works fine.
What could it be?
Thanks for your answers.

you can try to edit APN configurations or manually set the apns for EDGE/3G etc.

I've tried. It doesn't help.
I've partially solved my problem in this may:
1. I installed Proxuser`s Saga3D V4 ROM with STOCK kernel. (But after first run i do not get EDGE working (only GPRS)).
2. I make a factory reset from SETTINGS.
3. I boot up and get my EDGE working again.
And after this i tried again to install another ROM. This time Endymion V3.1 (Endymion V1.1 kernel). After first boot EDGE was working good, but after first reboot It disappeared again.
Could some tell? Could the reason be in KERNEL? RIL? RADIO on different kernel?
Forgot to add.. My current radio is: 20.28b.30.0805U_38.03.02.11

Hello,
Your network doesn't allow simultaneous data and voice, which in turn causes a setting in build.prop to screw up Edge. In short, you have to:
- open /system/build.prop with any editor that allows mounting /system as writable (ES File Explorer works fine for me and comes pre-installed in Endy)
- Look for a line that says: "ro.ril.enable.dtm=1"
- change to "ro.ril.enable.dtm=0"
- Save, reboot and you're done
Cheers

Oh yes. You're right. My network doesn't support simultaneous voice and data.
Thank you for your answer. I'll try and report the result.

I tried what you suggested, but the network still shows "G" instead of "E" even after changing the value of the dtm to 0.
Any suggestions?

First you should change that settings line in /system/build.prop and than do a factory reset from settings. And then you'll get want you need.

A factory reset!! So you mean i need to set up everything all over again?!!

Yeah. But you can do a full backup with Titanium backup! Do factory reset and then restore your stuff back.
Also you can try with nandoid backup, from recovery, it should work too.

In my case, I restarted the phone without a sim card, then inserted a different sim card and it detected EDGE network, after that i reinserted my original sim card and the EDGE network was there.
Try if it helps.

Thanks a ton for that tip!!
Saved me from doing a factory reset!!
I just removed the sim, put in another sim and booted up... it didnt have gprs activated but was from a different carrier.
Then i switched off again, swapped my original sim back into the phone and when i booted up, EDGE is back!!
Thank you for that tip. You're a lifesaver!

Great. Now problem is SOLVED!
Thanks to all who helped.

Thank's It was helpful.

[Q] cyanogenmod 7.2 Rc3

I guess I'll chime in.
Although I don't have a Samsung or an RC3 I have run into this before on CM7.1 along with many other users.
(Of course, a Data\Cache wipe is always recommended, especially if problems occur after a new ROM install)
Here are my suggestions:
1) Grab the free app Fix-My-Wifi from market and run it. Reboot with it enabled at boot at least once. Toggle Airplane mode on/off before and after rebooting. If this fixes it, Great, you can uninstall the app. If it doesn't fix it, you can uninstall the app and try the next step.
2) Next you'll want to remove any saved/restored APs. You can 'Forget' them one at a time if you'd like, attempting to connect after each removal, but it may be necessary to remove them all. Make sure you attempt to connect from the 'Wireless and Network Settings' too, and not from some other toggle. Reboot and Connect.
3) If that fails, it's been reported that changing the router's password type to WEP only (if I'm remembering correctly) can fix this symptom in some cases, as well as improving the data speeds through the phone. I may have the password type wrong, so try all password types that can be set as 'only'.
If you still cant connect I would redo\retrace your install, ensuring to wipe data/cache and only restoring a minimal amount of DATA with any of your backed up apps. Also, you should avoid restoring any 'System' apps\data (they're the red ones in Titanium Backup).
That's all I've got for ya to try at this point.
If it's still not working, more detail on what you've attempted so far in your troubleshooting and how\when the phone developed the problem might help another XDA'er provide you with a solution.

how about battery back up with cm7.2 mate ??? i asked u question while u r asking ,,by the if u like to say

[SOLVED] Wi-fi "memory" reset on every disabling!

Hello,
I got a little problem with my phone (so freak... I'm explaining)
I got a router before but now I changed it, because I switched to another operator. But it feels like the Wi-fi of my phone is not agree with that.
I "forget" the now inexisting router I had and connect to the new one...
...But I do this each time I turn off then on Wi-fi, and even after switching off the device with enabled Wi-fi!
For now I just have to remember one Wi-Fi router (and, thank you Kika Keyboard developers who made an extensive clipboard where I can store my password <3) but figure out what it will be when I'll have to save more passwords! So yes it's annoying. And I also already lost at leat 8 router passwords because of this strange cr*p.
Fortunately I got a Wi-fi retriever app but this is not auto connecting and this is no longer working!
That was the last point: even the router password retriever app is acting like I didn't connect to a new router since its last analyze!
So could you help me fix this annoying bug?
For now I got an hypothesis: I got XPosed and a device ID changer app.
And it contains an useless but impossible to disable option that is "changing the SSID"
Default configuration make your phone to display your SSID. But not with the local variable where your actual SSID is displayed! No, with the SSID you got when you installed the app. So you can connect to another Wi-fi and still got the same SSID (perfectly useless)
Rest of my theory is that messing up with SSID display may cause network state not to be saved properly. But this is only a supposition. And this is hard to figure it...
So to corroborate this theory, a subquestion: What is the local Android variable where SSID is stored? Tried %WIFI, %SSID but it doesn't work. And I didn't found it after a quick search.
Thank you in advance!
Sorry for wasting your time with so much text :/

There are also people conplaining this problem.
In the link pasted on the top, there is a possible fixes for some fortunate people... But actually this doesn't work for me.
-First, ro.secure.storage or ro.securestorage. thing does not exist on my device. I don't even know if it existed on my device.
-Second, there is something about /efs/ss_data, a file that also not exists on my device.
So I don't know if it's because Samsung built it differently or it has been removed. Keep checking...

After a check of my backups I saw that I got none of the file and property mentionned before.
So I'm unable to know where is the problem...

If you're saying that you looked in build.prop but you don't see any lines that say ro.securestorage, you can add those lines if they don't exist. Just edit build.prop and type the line in at the bottom then save build.prop and reboot the device.

This is what I did. Uneffective.
Why? Because I never got this prop before.
I checked my backups where the Wi-fi worked perfectly in case all of this would be due to the fact that this prop vanished because of a dark and random informatic process. And after checks I finally realized that I never had this prop...
Same thing for the file I mentionned before, located in /efs. I didn't lose it because I basically never got it.
So... This means that my device save Wi-fi informations by another way. And because I don't know this way, I cannot fix it...

If you got a different router but kept the same network name and password and didn't change anything on your device, that might be the issue, your device is probably looking for your original router because the information you originally saved was saved while the other router was in use.
Try backing up your apps, app data and settings but don't backup your wifi settings or saved wifi information. Then boot to recovery and factory reset and wipe cache and dalvik/ART. Then reboot the device, when it boots to system, try connecting and signing into your network again and see if it saves it correctly.
If the backups you are talking about are nandroid backups created in TWRP, you can also try doing an advanced restore in TWRP, you can restore just the data from your previously working backup without restoring everything else.

Well, tried what you told me and this didn't end well...
I used to make a factory reset of my phone. The problem was fixed. When I connected to the wifi first time, now each time I disabled and re-enabled it automatically reconnected (auto-connect is miraculous lol)
Then I flashed data back with TWRP recovery (backup by Nandroid app because I got a classical TarFork error with TWRP 2.7.0.1...)
When rebooting to Android it spammed 1M layers of various program crash message box.
Then using TWRP I reflashed this time everything I got then rebooting to Android the bootloader freezed.
I thought my phone was dead until I realized I could boot to recovery again. So I flashed an older backup and lost some data (fortunately I backed up SMS and apk).
My device is safe now, but this misadventure taught me lots of things:
-When I did a factory reset data has been erased, but system still the same and it reworked. So maybe an app is locking my Wi-fi like this. But which?
-Nandroid backup app is NOT reliable. If your device isn't clearly identified your backups are corrupt. Gotta erase all Nandroid backups I made.

Solved. Bug due to a bad TWRP backup. Made a fresh install and everything is fine now.
Thread closed.

Hello from SoCal
I'm mighty impressed with the custom roms I've come across on this amazing site, but after several frustrating days, I've decided to go back to stock firmware for my cdma moto g3, XT1548. (Huge props to lost101 for the detailed and easy-to-follow post.)
It's such a pleasure to extend the life and usability of an older phone by installing custom roms, and I've never had any problems until I bought the g3. But try as I might, no matter what rom I installed, I couldn't restore mobile data.
After installing the rom, it seemed easy enough to complete the final step and reset the carrier by inputting ##72786# via the generic phone app. But it never worked -- instead of going to the SCRTN settings, the dialer treated it like a phone call. I googled around for days, tried changing various settings -- no luck.
Actually, I did manage to upgrade from 5.1 to 6.0 by leaving TextNow for another Sprint mnvo, so it's not a total loss. Sure did like some of the 7.1.2 roms I installed for a bit, though . . .
Did I do something dumb, or is it the case that a certain set of conditions can limit a phone's ability to be upgraded? Any thoughts? Again, LOVE this website. Thanks!

If you're using the Virgin mobile xt1548, you just need to set up the apn correctly. Use the one in the attachments. This how I do it.
1. Clean a flash ROM.
2. Mount /system in TWRP
3. Copy the apn-conf.xml with TWRP's file manager to /system/etc
4. Chmod the apn-conf.xml to 0644
5. Unmount /system and reboot.
6. Open settings and find the cellular network settings. Select the following.
Preferred network type>LTE
System select>Automatic
CDMA subscription>RUIM/SIM
Access Point Names>APN1 Virgin Internet LTE (if there is an APN2 delete it.)
After that select "carrier settings". You'll get an error, all radios will reset and LTE will show up in a few seconds.
For future reference do not use dialer codes on custom Roms for anything network related. This is asking for some serious headaches.

Thanks for your post Winchester. I have Sprint, which is cdma. I understand editing the apn settings only works for gsm. I did try it anyway for kicks, no luck.
Oh and thanks for the heads-up about dialer codes on custom roms -- I had not heard that before.
