I have a Matorola One, I was looking for something in the hidden menus and I accidentally clicked on the RadioBand one, now things like call and mobile data won't work, I already tried erasing modemst and cache (as seen in this method to fix it https://forum.xda-developers.com/g5/how-to/recovering-2g-3g-set-radio-band-to-usa-t3668767), I tried to delete and reflash the rom (I did make a full wipe before I did)that I had and just now I tried to go back to the stock one, but the problem persists.

Hi,
I am trying to restore a couple of nandroid backups, but a Device Administrator app gone "quirky" seems to materialize no matter what I do. I did a CWM Wipe, restored the nandroid backup before the app went bad. However that did not work, the app was still misbehaving. So I wiped again, restored a nandroid backup from before I had installed the app. Still the app shows up again. It has in effect locked me out of the device.
Can anyone tell what can I do to get rid of the app?
Are these Device Admin app supposed to persist like this? Or am I doing something wrong?
Do I need to choose a different wipe mode (I chose the normal one, which wipes /data/, /cache etc). I did not try to wipe /cache separately, as the first wipe does that by itself. Neither did I wipe the dalvik cache, as I thought they are not relevant here. I don't see any relevant files in the sdcard either, though how the app reappears in the nandroid restore before it was installed is a mystery.
Should I mount more partitions before wiping, like the data/cache etc.
Since the wipes don't seem to make it go away, I am not even sure flashing a different ROM would get rid of this app either, however I can try that (since I was planning to anyway, before this mishap). If that doesn't work either, I might just have the most unusual case of bricking ever.
The XDA forum does not seem to be much info about device-admin apps and my search-fu is not good enough today to find anything directly relevant about the other stuff.
PS. btw the app actually modifies the lockscreen. So I don't actually see the files it has with the pre-app restore, however the lockscreen still comes up, perhaps because of some remanant of the app or because of a setting it left in there somewhere.
efs?
Just to add more info, I see some files in /efs, which look relevant to the lockscren/ They have file names like this "/efs/cryptoprop_lockscreen".
Would these files store the data this app stored. I fortunately have an EFS backup, should I consider restoring these files.
If someone doesn't know the answer, can they suggest which devs would be good to ask about this.

Do a CWM wipe, and turn off the phone when done by selecting "Power Off"
Now enter download mode, and ODIN flash a stock ROM.
Then re-root with CF-Root and install custom ROM if desired.

Thanks for the help pulser_g2. I am still concerned about the files i saw in /efs related to the lockscreen (see my second post). Would the stock ROM overwrite settings/configuration inside /efs (I guess since the IMEI etc are all in there, that might not be the case)?
Got through finally.

OK this worked.
However after I Odin flashed the stock rom and rebooted, I got this
1. First got a different kind of lockscreen.
2. I entered the wrong password five times (after trying the Device Admin alternate password, my Google password, a new 2-step auth password from google) .
3. it said something about wiping sd card. I couldn't catch it (I should probably have videoed this using my point and shoot camera, but this did not strike me then as it was 2am).
4. I was hoping that the stock ROM will boot, cause it stayed on the Samsung logo for too long. (I had already ordered my USB Jig on ebay anyway, but it could have taken time because of my being far off from the seller.). Finally I got the Android Welcome screen and I let out my breath.
In any case, things seem to ok right now. I feel a slight slowness in the rooted stock ROM from my earlier rooted stock ROM, but I am gonna flash a custom ROM later anyway. Thanks a lot for your help pulser.
Hello all,
For some apps and menus I cannot access the bottom of the screen. Just a small enough part that makes it impossible to select any options or buttons. Accept or decline for example or Settings when hitting the menu button on the launcher screen.
As I mentioned it doesn't always happen.. When on the launcher screen I CAN access the quick bar at the bottom of the screen. It also doesn't happen while I am in the settings menu as I can also access About Phone.
When I first started to notice it happening I was using ROMeOS3D v134 So I tried flashing Mwakious3D 3.0. Before Flashing I factory reset and formatted everything but SD Card in ext4 recover.
It seems odd that it only occurs for some apps and menus which makes me want to rule out Hardware, however reflashing a new FW with a full wipe didn't fix the issue either.. When Flashing, I did no backup/restore except google's own account app backup/reinstall.
Any help is greatly appreciated.

hmm.. no one has any ideas? i was searching the web a bit and saw some people with the attrix had a similar problem due to problems with their pds partition.. is it possible one of my partitions is messed and needs fixing?
Perhaps make a NANDROID backup and run the Superwipe utility and flash a super stable ROM? One based on a official non-leaked RUU (Which would mean Gingerbread) and see if the problem persists? (Perhaps just flash a complete stock rooted ROM?)
And don't begin restoring any apps or old data or flash stuff on the "stock" rom, just take it as it is and test out the errors you were having in your "normal" rom.
I'd like to put extra emphasis on "Superwipe" instead of normal wipe in recovery, as Superwipe also wipes certain partitions that a normal wipe doesn't cover I believe.
If the problem persists, then I can only be led to believe it's a HW issue..
As of yesterday, my CM7.1 phone won't boot - it gets stuck at the "rotating arrow" blue Android for ever. It's a Samsung Galaxy S II GT-9100.
I have been running CM 7.1.0 for several happy months now, and haven't tried to install or upgrade my ROM. The last action I took before this happened is that I made a full system backup (using CWM 5.0.2.6).
That backup is present on the internal memory. I can boot into recovery, mount drives and access devices using adb shell. So I do have an opportunity to fix what's broken, if I can work out what it is.
Given that the last thing I did was a backup, I checked to see if any of the partitions were full, but none are. (None is more than 42% full according to df; although strangely, df does not show any partition mounted on /.) I tried making another backup, watching carefully - that worked fine. I tried restoring the first backup - no improvement.
I've also tried wiping everything Recovery allows me to that's non data-destructive - cache, Dalvik cache etc. It hasn't helped.
How do I work out what's wrong? Is there a boot log file anywhere which might give me a clue as to what is wrong? I've searched for "*.log" but can't find anything obvious.
I don't want to do a factory wipe if I can avoid it, because obviously that will lose all my data. If I do a factory wipe and restore just the data partition, does that put me pretty much back where I was? If so, how do I restore just the data partition? The Restore option in CWM Recovery seems to do full backups only, and only from a particular directory.
The original CM and Google Apps zips are still on the internal SD (same versions as are currently not working). Would it be worth trying to reinstall those, without wiping? Or would that be data-destructive?
Any other ideas?
Thanks!
Gerv
SOLVED - remove 0-byte data/system/profiles.xml
I tried doing a full factory reset from Recovery. This got the phone booting again, but without any of my data . Fortunately, ClockWorkMod has a "partial backup restore" function. I restored the data partition... and the phone stopped booting again.
So this is progress. I now had some idea where the problem lay. I finally found it using a laborious 5-minutes-per-cycle manual bisection technique. Delete half the stuff on the data partition, reboot, if it still fails, delete more, reboot... once you get it to boot, restore the data partition, narrow it down further. Once you find a top-level directory, repeat the process inside it.
The result: the existence of a single 0-byte file stopped my phone from booting entirely. The file was: data/system/profiles.xml.
I have no idea what that file does (there are only a few references online), how a 0-byte version of it got created, or why having it existent but empty breaks things but if it's not present everything works fine. I have no idea if anyone else will ever see this problem, or if they will ever find this forum post. But still, here's my Wisdom of the Ancients (google the phrase for the relevant XKCD comic).
Hey guys.Im kinda a noob, so bear with me. I have a SGH i747 (att galaxy s3) and I rooted it on my mac using motochopper. I backed up all my apps and system data with titianium backup to my SD card, and i also backed up my stock ROM to my internal storage using ROM Manager. I then downloaded liquid smooth using my phones browser, and then I selected it within ROM manager and clicked "reboot and install' (keep in mind, i didn't wipe memory or anything) So it was stuck at the boot screen. Then i realized what i did and went and wiped data/factory reset, dalvic cache, and the other cache, within Clockworld mod recovery (vol up + power + home). After that, it worked, but only to find that all my apps were gone, and the play store and browser app didnt work. so basically softbricked however I can make phone calls and text (lost all contacts). Then i went into cwm and tried to restore my phone, at first it came up with two backups (neither of which had the name I named my backup) but said no files found and then when I mounted my storage, the bottom one said md5 mismatch but the top one worked. the top one would work for about 6 min then while it was restoring data it would reboot into liquid smooth and i would have like 3 apps i didnt have before (other times i would get stuck at the boot screen). I also tried restoring it right after I wiped data/ factory reset and cleared the caches, but then it would get stuck at the liquidsmooth boot screen. Tried pretty much everything.
I just want my phone back the way it was before root or anything, with all my data. But I backed up all my stuff besides apps to KIES, so willing to reset it to stock firmware if possible
need all the help i can get. thank you all very much
I installed V1 of barepop on sunday and everything was working perfect. Today I remembered that I had some memos in quick memos that I needed, so I restored my backup (I think it was ZV4), exported the memos, and then restored the backup of Barepop that I made right before. However, now most of my apps crash or don't open. For example, when i open instagram it stays open but when i begin to scroll it FCs. And when i check the app info, it says that it has 100MB of cache. I tried doing a clean install again, but I get the same problems. Most of my apps crash or don't open. Does anyone know how to fix this? Is it a problem with the modem or conflicting data with KK and L?
Did you wipe:
Dalvik Cache
System
Data
Cache
All of these?
If you didn't wipe data from a past rom it can really mess things up. Try wiping those four partitions and then restore your backup.

Yeah. I tried again right now just in case, and I run into the same problems. Could it be a problem with me not switching modems when I restored the zv4 backup?

Maybe. The modern isn't backwards
compatible. When you go back to zv4/6 you should flash the modem also. And maybe the rpm,tz partitions. Not sure on that yet.
It almost sounds like your internal SD for corrupt. You might have to format it. Backup your files first though.

Okay I wiped internal and installed barepop v1, and now i have no softkeys at the bottom of the screen and the status bar does not show up either.
I Installed V.2 and I get the same results
I was able to install CM12 with no issues. I don't if this helps narrow down the problem
Use the flashtool and go back to zv4 and reroot and then do this http://forum.xda-developers.com/sprint-lg-g3/help/fix-missing-wifi-calling-zv4-t2842102
It should fix everything
