[Q] my phone desktop disappeared - Android Q&A, Help & Troubleshooting

Hello!
I uninstalled some system applications on my phone and I instantly regretted it and restored applications from back-ups using Wondershare MobileGo for Adroid. However, although it seems all the applications are working again, when I unlock the screen, I get a black screen - no desktop, no application list, but with the notification bar on top which works properly. The clock and calendar are displayed on the unlock screen and the alarm clock woke me up... I got some notifications on the black screen: process.android.acore, process.android.gapps and process.android.vending stopped working, process system stopped working.
How can I solve the problem? Thanx!

Since you have installed system apps, i assume that you are rooted. Now if you have taken a nandroid backup before attempting this, you can go ahead and restore that. If you dont have one, try to do a data wipe/factory reset from recovery. But before doing all these, put a ROM in your SD/internal storage as a backup to flash if something went wrong.

Do a factory reset.. should be fine but if doesn't work take a backup of you data and re-flash your rom

I followed your advice.
I had problems with a factory reset - I did a hard-reset and when a phone turned on, process com.android.browser had immediately stopped working. The screen (which had a message "touch the screen to proceed") dldn`t react to touch, so I got stucked.
I gave up and installed the whole new ROM in the end.
What an adventure...

[Q] Optimus T stops functioning after rooting

I recently purchased an Optimus T and rooted it with z4root and then installed Titanium Backup to delete some of the preinstalled apps, like the Pacman Demo.
As I was removing each app, (~5 at this point) the Home button suddenly stopped working, followed by total phone death. Even after factory reset, when I was trying to access the phone, eventually I was shown a "... setup.exe stopped responding..." (or something like that) message and my phone just stayed stuck on the booting screen (android) every time I restart (w/o entering factory reset).
Does anyone have any ideas, or know which apps can prevent the phone from booting properly? A list of safe apps to delete would be helpful too. I thought I was pretty cautious with removing only non essential apps, but it seem bricked. Thanks again!

About list off apps, I have to agree. Even it there is litle problem with dependencies, some minimum describe of these issue will be great!!
So, about your problem - I think, that you will have to download original ROM and do flashing with KDZ_FW_UPdater. (search on xda for more information).
But definitely, if it's possible I would try to install custom recovery throw adb shell (android SDK tools) and do backup of system for possibility to recovery or saving at least few data, and after try wipe and install one of custom ROM.
This happened to me after I tried deleting preinstalled apps on my Optimus One... Sent it in for repairs since it just stopped working. The tech guy said he did a "software update" and everything is good as new (except for the LGMITS error once in a while)
They didn't even bother trying to fix mine. They just told me to send it in and gave me a replacement.
So I finally figured out what I did wrong - basically when I was doing the deleting, I accidentally deleted the LG Home app, which effectively deactivated my (duh) home button and effectively stopped everything from functioning properly. For some reason I thought it was just a simple link from my phone directly to the LG website, as would happen with new PCs very often. Well... won't be doing THAT again.
However, my web2go button isn't working. I have to force quit every time I try to click on it. Can I just get rid of it or will it just give me more trouble later on?
At least you knew what went wrong with yours... I was just erasing CarHome and Layar and the LG App Adviser among other things i wont be using like Twitter and Latitude.
And they even gave you a new one x__x I had to wait 5 days before everything was good as new. After the first fix, USB debugging and mass storage stopped working so I sent it in for another "software update"...

Unchangeable phone

Hello,
Basically, my phone works. I can call, sms, photograph and so on, but:
When I try to flash new rom, via Kies, Odin or other tool everything goes smoothly, blue progress bars advance and complete, phone reboots, and ... I have old rom, nothing is changed, no data is deleted.
When I install new apps they work until I power off phone. After power on new and updated apps are gone, deleted SMS are back, it looks like the phone inside was frozen in time some time ago and all that is going on is going in ram or some virtual machine, and vanishes.
It happened some weeks ago, I cannot recall when exactly. Something I installed was suddenly missing and SMS after reboot came back, but I ignored it then like a sporadic glitch.
I just discovered, that I also can't do factory reset. System recovery <3e> shows, but doing wipe data or wipe cache has no effect. Nothing gets wiped, apps and data remain intact. The only unusual thing I see in the recovery console is:
Can't access to '/system/csc/PLS/system/'
Is it a virus or is it just broken or what?
zieloniak
I suggest doing a deep clean...

Samsung Galaxy Nexus i9250 HELP PLEASE!

My PHONE TO PULL MY GARBAGE
I have a Samsung Galaxy i9250 Nexys an a week ago began to reboot itself.
It is reset whenever you are required to processor and RAM, Example, in Settings >> Applications where the phone reads everything he has in memory is reset each time, to enter SETTINGS / APPLICATIONS also restarts as well as when use any other application.
Will not let me uninstall anything at that point reboots, and when I take pictures saves, but the next restart any applications that were installed (which could be installed) no longer appear, not the pictures that I make, videos, conversations via whatsapp and any activity that has taken the phone is not registered and the telephone keeps the settings at the time the problem appeared. I have photos and videos in the gallery to take before having the problem (automatic restore), removed and reappear with the reboot !!!!!!!!
Tried everything and nothing worked, NO WIPE (performs the process, but at the restart as usual), do not format (performs the restart process but makes no change), does not reset, does not restore factory settings, NOT WORK WITH STEPS NEXUS TOOLKIT.
Take a technician and he said he does not know why not answer the phone.
I played in the TWRP (recovery) to see if anything not to at least stop and restart hanging up to start reinstalling from there.
Nothing worked.
This is a solution? It is a phone that I have two years ago, I rooted six months ago and never had any problem always with flawless operation.
I could help ????

dozens of apps suddenly having a crashing party

I've got a number of Moto G that have been working fine for months. Suddenly, one of them is constantly having apps crash. I'm talking literally every second. As fast as I can close the crash notification popup another one pops up for another app. android.process.acore, com, com.google.process.gapps, dozens of others. A reboot will fix it for a few minutes, but then it goes on a frenzy again. I've tried wiping the cache and dalvik cache with clockworkmod recovery. I've tried uninstalling updates for google play services. I unfortunately don't have a backup created for this device. I would try to factory reset, but the last time I tried factory resetting a rooted Moto G through the android interface it bootlooped. If I can't fix this, is there a way in clockworkmod recovery to "reset" back to just after I rooted the phone? If not, I may be able to copy over a backup from a similar phone, but I'm not sure if that would work.
EDIT: I think this phone might have just **** the bed. Bootloops when trying to turn on normally (unlocked bootloader warning screen, then motorola spinning world graphic, then off). Volume Down + Power in off state does nothing so I can't even get into the bootloader.

Of how WiFi won't turn on and I don't know that I'm doing - Galaxy Grand 2 G7105

I got my hands on a Galaxy Grand 2 sm-g7105. Performed a factory reset from device and the system worked nicely enough. A particular third party app I wanted to use wouldn't load so I kept tweaking.
I rooted and set up a CWM recovery with Odin, then considered going with Resurrection Remix. I made a backup with CWM, wiped the device and set it up. It looked great but 'audioFX.apk' or something along those lines kept crashing every 30 seconds or so. It didn't cause me any problem besides the annoying crash notification, so i figured I could just remove the apk and be done with it. To my dismay, then the notification then piled up non-stop and the system become unusable.
I went and restored the backup on CWM. Then I'd get error notifications for this and that stopping working (basically the apps present on the backup that weren't on the stock rom), so I figured the backup was useless. Another mistake, I guess.
Performed another wipe, deleted the backup for space. Tried removing every piece of bloatware I could find before unrooting (I wanted to do that). Finally everything seemed to roll... except I deleted some important apk, SecDownloadManager I've come to believe, and at that point the Play Store couldn't update a thing, it got stuck on 'Downloading'.
So I did another wipe, just to find out that didn't restore the missing apks. Got my hands on a stock rom for my model (a different build than my origibal one, but to hell with it... right?). I got that working work Odin, but to my surprise that didn't seem to completely restore the apk mess, and I got a ton of crash apl notifications and even after logging on Google the play store didn't let me in to try and see if apps could update.
Finally, I found what is supposed to be the device's original rom. Odin'd it all the way. Everything seems to be where it belongs, but I cannot really check 'cause... NOW THE ****ING WI-FI WON'T TURN ON. It's not like it doesn't connect to my network, it just won't activate. I press the switch, or goes back off.
I tried rebooting, taking out the battery for some seconds, performing a factory reset from within the system, wiping from CWM, dialing *#0011# to access service mode and deactivating power-saving mode. Nothing works.
HELP, please.
I'd be happy if the WiFi just worked, but knowing why the hell a stock rom should give any headache or what I'm doing wrong for it to go so wrong might be a step towards the solution.
PS: I'm writing this as I recall, so the details might not be completely spot-on, but the broader problems were those.
