Download stock rom from below link. Flash tool and flashing process also given in the zip.

You might just be able to sideload a launcher apk via adb.

Instead of flashing rom,
First try to install any launcher from playstore since you can open settings
Set it as default launcher from settings itself after installing
If the problem still exists then you can go for flashing rom
Also press the thanks button if I helped

[REG] Remove service provider name from curtain

I experienced some problems due to Task Manager.
I added apps to auto end list, so when screen was off I had to re-enter the preffered input method/live wallpaper etc.
Anw, the main problem is how to remove the service provider logo from the curtain, cos I can't see any notifications.
(see picture!!)
Any help appreciated!
Thanx!!
installing GingerBlur will remove the carrier logo but will not push it down to the notifications window. I did the same because Vodafone AU was becoming a similar annoyance
thanx, but i dont want to install motoblur!
any other solutions?
all other problems sovled!
I was just adding to auto end list all programs via task manager, to have less battery consumption!

you wont be able to remove the carrier name from the bar without rooting/deodexing the phone, so you can either
root then deodex then install a No ATT bar from the development section (can't remember the link though)
- OR -
Root then install CWM (oldest available version) then install gingerblur.
sorry :/

[Q] How To set administrator settings ?? :|

Hye all.. Can anyone please tell me how can we change the administrators settings in lg P500.. ?? Whenever i try clicking the administrator tab in the settings page, nothing shows up.. Need this to set locks to my messages and certain apps..
I don't think you can create administrator rights, but on Market there are apps that can set password protection on other apps, search there.

Download the app Appzorter from the market and shuffle your apps alphabeticly.
This is the downside with stock TouchWiz launcher. You could get http://forum.xda-developers.com/showthread.php?t=1061883
which does sort apps, but it's a little buggy sometimes.
Or use a 3rd party launcher (I use GOLauncher EX atm, which is really nice and fast.)
ok guys i find the solution!!! i made again one format and it work, all are ok now!!!
The solution
Yes exactly as frixosmjoker said .. do factory reset and everything will be ok

[Q] Android 2.2 home launcher deleted

Dear All,
I have accidently deleted the Home launcher app of my Android 2.2 mobile (Chinese H3000 model); as a result it is not going beyond the screen saver at all, the screen just turns blank with no widgets/shortcuts/buttons appearing at all!
Although it rings & receives calls when called.
I have already tried factory reset option.
Can anyone help me resolve this problem

You need to install any launcher

Dear Mr Akshay,
Thanks for responding but none of the two options work - Couldn't see play store in the launch on pressing & holding Home key; was able to access play store via gmail login on my PC & tried downloading - the message did appear that it will be loaded shortly on the device but thereafter nothing on the Phone. The main problem is that I'm not getting any menu buttons at all, it's only a blank screen as soon as I unlock the screen saver i.e I have no settings button or any other button. While connected to PC only the sd card gets read in the windows explorer on PC, but there's way to open sd card on phone!

Missing launcher fixed!
Hello to all!
I note a lot of inquires on this site many of users using programs's like Titanium backup and other "advance" users just deleted Launcher as soon is they get there hands on the root!
Then they find out that they can see only black screen. Many of you try to replace it with dozen of software's but find out that Debugging mode is off. And is no way that can be enabled.
Well not all that bad as it shows. Firs at all if you are still log in to your Google app go to your account on Google go to apps and download, it will stated online that item is available on your phone now it over, top bar you can see it and install it come to the phone via Ethernet - WiFi or 4G.
If you already reset your phone or hard reset and you still see the black screen watch my video on how to get launcher in to your phone very simple, using dongle, other Bluetooth enabled laptop or smart phone!

I has face the same problem as you and i has done it right way
Since you has root your android phone,I know that you are very excited to remove those unusefull apps same as me.I got the same problem as you that I also used China Mobile phone and can't done any of the suggestion here(suggested such as flash those .zip in recovery) that won't work on china mobile type.When I has delete my home launcher,one thing for sure,the screen is black after turned on and I did reset factory data in recovery mode(worst move ever cause my wifi connected password has totally gone).So,my first effort was I take my moms tablet and start downloading any launcher (.apk) .Okay,since before I get into black screen,If I press lock key,the ring menu will appear right?.I used those ring menu as a door to get into my bluetooth connection.At the ring menu,I drag it towards 'camera',and then click on the pictures that you have captured(gallery in camera).Just pick any random photo and click share (via bluetooth) after that,I send a photo to my moms tablet(actually just to make pairing cause can't go to bluetooth settings).After paired,I try to send the home launcher.apk from my moms tablet using bluetooth connection that has been paired this before.Eventually,after receive the apk file,I can't open it.It says "no application can perform this action"(but,maybe you should try it first.Maybe it'll work on you.If not, try another one of my step).So,I was frustrated having an unsolved solutions through internet source information and I almost dump my phone in the dustbin.But then,I try another way.This time,I use the same door/way(through camera in ring menu).But this time I try to send through gmail(I don't think that I have any wifi or data connection after reset factory data eh?!).But boom !! The idea comes to me that I try to send the photo through gmail account just to make a wifi connection(again,because I can't go to settings).So,after I try to send it through gmail,the Sign-In screen will appear(but remember,I don't have any wifi/data connected.What I'm going to do?!!).I just filled in my email and password and click Sign-In.Of course the connection can't be made because there is no connection at all.But the trick is,when you wait for a few seconds,you will be asked to make a wifi connection(automatically the wifi around you appear in the list).So,make a connection through any wifi and sign-in(yeay!!connection established !).After that,I try to send home launcher.apk through gmail using my mom's tablet to my phone and a few moments later you will get a gmail notification through notification bar.Click on it,and click install.There you go.You are safe again.

Question One Plus 9R Share Option Is Not Working

I have bought oneplus9R 12GB/256GB India version
Oxygen OS11.2.6.6.LE28DA Model LE2101. I had recently formatted the phone and I am using it. The phone was working fine but after about 3 weeks, I started facing an issue.
When I am trying to share any file using the share option in Whatsapp or in file manager etc.
The Share window opens as in the image shown but all icons remain black. I can't select any. After some time, I get a popup "Android System isn't responding. Close app or wait?". And then the Share screen disappears. Omegle.top
I read that I need to clear the cache of System UI and Oneplus Launcher which I did but still the problem remains. Need a quick fix solution so I don't have to reformat and reinstall all my apps and data. click here
Reformat is the last option.
Please help me. Thanks in advance.
