[Q] g2x Major Problems after Rooting / unRooting

Alrighty.. This phone has caused me so much time and trouble, I finally decided to start a thread. I really cannot find an answer for my problems by surfing...
In the beginning, all was great. Then I wanted to root my phone...
I went here and followed these instructions to root initially.

(Stock Gingerbread OTA 2.3.3 Rooted)
I started to have problems:
-WIFI kept shutting off upon sleep. I depend on WIFI because I only have a 200MB plan..
Also, I have low signal in my apartment, so I use wifi calling very frequently. After about 10 minutes, wifi calling disables itself.
SO, I wanted to UNROOT. The link that said 'UNROOT' did not work..
Next, I used this link to unroot..

I returned to stock froyo OS. BUT i still wanted gingerbread!! I tried to use the LG update desktop tool, but it kept on saying that 'the phone was already up to date.'
SO, I ended up 'installing from zip' the backup that was made before I downgraded to froyo.. Unfortunately, this left me back at square one: A rooted gingerbread.. Exactly where I was before.
I went to this link next.

I used the 'UNROOT ZIP', and it unrooted it!!
Seems perfect right??
BUT, ever since I did that, my GPS doesn't work. It is unable to pick up my location.
I tried to 'restore to stock' using BOTH the option while the phone is on, and using the 'clockwerk mod' (Where you hold power and the down button).
I just want things to go back to the way they were.
I'm hoping that I can just have a NORMAL 2.3.3, with GPS working, and everything back to the way it was before I started this whole 'root' journey..
Thank you so much ahead of time for taking the time to help me. Your 5 minutes could save me hours..

try restoring to stock, 2.2.2, then get the LG Updater tool to "Recovery Phone" which is at "Customer Support" and the last one, enter your phone model, and serial number, and it should recover it to stock with no problems for you. Good Luck.

Wifi is suppose to shut off on sleep mode unless you configure it not to.

I will try this now.
Thanks. Hopefully it works.

It still says 'Update not required' after I use the recovery version.

It is saying that because just flashing 2.2 you are still on the July baseband which is telling the software you are on the latest. You should be able to find a stock nandriod in the forum somewhere to flash Gingerbread stock.

Go to Wireless and networks > Wifi > hit menu > Wifi sleep policy > never.

I was unable to find such a thread. I decided just to root it and go with the 'eagle' and deal with random problems..
However, the front facing camera keeps on stretching the picture..
Any thoughts?

FFC issues are common on non-stock roms trying to use LG camera instead of Android stock camera. Rooting your phone cannot cause wifi issues, etc. unless you made some errant changes to system files. Rooting does nothing but allow you or programs to get what is called in the Linux world SuperUser permissions. It allows you or the program to change or do anything it wants and removes the restrictions placed on the handset by the manufacturer and/or Google. All the rooting process does is add two files to your system and set the proper permission for su to be able to become root. The SuperUser.apk is the gateway to root. It is there to protect you from malicious programs getting root, as you have to approve all root access requests. It is actually very safe unless you do something stupid.

[Resolved] Galaxy Tab 2 Screen of death issue! Please help me!

I posted this in another thread and no one was able to help me. So I am posting it in it's own thread hoping that someone can. I know a lot of people having this same issue.
Guys, I have a brand new Galaxy Tab 2 that I bought yesterday and after following the first rooting guide, the one that uses Heimdall to flash a .pit file and a "boot-bjr.img" file, I'm having a really serious issue.
So I went through the process (not the first time I rooted an Android device) using the original heimdall method and it was easy and simple. After the root I made sure by downloading root checker basic from the Play store. I was indeed rooted. But then something weird started happening. The screen goes into standby by itself after a few seconds like normal, but I can't get it to wake up from standby. I have to shut off the device by holding the power button and then turning it back on again. When I do that it works normally again until the screen shuts off either by me pressing the power button to do it manually, or until the screen dims out into standby. I've tried wiping the cache, I've tried a factory reset, and I've even ran the process again all over using heimdall. I'm guessing it's probably the kernel that gets flashed using heimdall? Please help me out here because I only got this device yesterday and It really sucks that it's not working. Someone suggested that It's the kernel's problem and I need to be running the original kernel which is (Kernel version: 3.0.8-292098-user [email protected] #1 Build number: IML74K.P3113UEALCB). I checked and I'm running kernel version (3.0.8-275757-user se,[email protected] #1) Build Number: (IML74K.P3113UEALD3). He also suggested that I do a factory reset to reset the kernel. I did using the stock recovery and the kernel remained the same modified version. Is there anyway that I can revert back to the stock kernel? Someone please help.

I was able to fix it easily. I found someone online who had an identical Galaxy Tab 2 and had them make a nandroid backup and send me the files over dropbox. I got an md5 mismatch error which was simple to fix after some googling and then the restore went fine. Now I have no problems with the tab and the kernel is @SEP-66 #1 instead of @SEP-103 #1 which was causing the problem.

[Completed] Formatting Samsung S3 Problem

Hey, so basically I'm in a situation where I have no idea what to do.
I recently just got a new phone, and am going to give my Samsung Galaxy S3, SGH-T999V model - from Wind Mobile to my Dad. Basically, when I first got the phone - a couple months after, I decided to try Rooting it, and I did, successfully. Since I didn't really know what to do with my rooted phone, I decided to unroot it - then tried rooting it again some months later, but it didn't work successfully. Basically my phone wasn't rooted, but I had the "Team-Win" recovery on it.
I wanted to bring my phone back to it's original state - and have the stock recovery on it. After some Googling, my solution seemed to be to flash the stock rom for the SGH-T999V model onto my phone using Odin. And I did that - and it worked successfully. But I still couldn't check for OTA updates or anything, it said my phone had still been modified in an unauthorized way.
Now that I need to give the phone to my Dad, I have to format the device and erase everything. This is where my problem starts. When I try to format it (using the Stock recovery), I see a bunch of error messages, with the Android logo falling down in a kind of dead way. I reboot my device, and nothing changes.
It still has all my data, and everything on it.
Sorry if this is the wrong area to post this (I'm relatively new to the forum), and if my problem doesn't make much sense - I've tried being as detailed as possible. Could anyone help?

Hi, thank you for using XDA Assist. Flashing the stock firmware should show you to get ota's. This should have everything you need,http://forum.xda-developers.com/galaxy-s3/general/samsung-galaxy-s3-sticky-roll-thread-t2344125.

[Completed] [Q] Don't really know where to go from here

Alright, this is a long story.
I own an LGMS500 from MetroPCS (or the LD500 Tmobile version).
A year back I rooted the phone, but a couple of months ago it started to act up Giving me the message "unfortunately, the process com.android.phone has stopped." at first a restart would fix it but a few days after it got to the point where I couldn't use it. So I set out to fix it.
I knew I needed to flash it back to stock ROM since a factory reset and a hard factory reset didn't do anything. But for some reason I decided that flashing a custom ROM was a better Idea. I ended up flashing the xperia ROM and it soft bricked it ( It turned on and booted but wouldn't let me past a black screen, yet I could lower the status bar).
Then I tried to flash the stock ROM or the "MS50010e_03.zip" to load with KDZ. from:
http://androidforums.com/threads/metropcs-unbrick-kdz-for-metropcs-updated-11-13-2013.788365/
But every time I tried it it came back with a parameter error, I changed many things with no avail, Then I figured that since the phone had a tmobile version I flashed the tmobile stock ROM onto the phone and it worked, even let me use data. But after a few days it stopped letting me use data, with a "Service Disabled message on the status bar where it should've shown the mobile carrier. When I went to check my phones mobile data status I noticed that My IMEI # was unknown.
After some research I came to the conclusion that something was wrong with my EFS folder since that's where all that information resides.
At the moment the phone restarts after about 3 minutes of usage, I should also mention that I rooted the phone after the tmobile stock ROM install because of what this thread suggested I should do.
http://forum.xda-developers.com/galaxy-s2/general/guide-recover-imei-9-steps-t1264021
Basically I need to know if my conclusions are correct and what kind of steps I should take to recover the phone if possible.

FIXED it
I just loaded the MS50012b_00.kdz from:
android creations on the weebly site (sorry I can't post links yet)
This is the only image that worked the first time. After that my phone worked normally, accessed the mobile network correctly and the crashing stopped.
I even installed the xperia ROM that is on that page. Everything is running smoothly now.

Samsung Galaxy S4 I9500 - NO SIGNAL (IMEI/IMEISV:null/null;Baseband Version:Unknown)

Hello everyone,
As this is my first thread, and I have been reading previous assists based on IMEI fixing and couldn't find the answer I am looking for, I really hope that the XDA community can help me fix my Galaxy S4 I9500. I will try to explain the problem the best I can, and I will create a list of every solution I have tried in the 3 week phone fixing saga I have.
1. The problem :
My friend decided he does not need this phone anymore, everything was fine with it except the battery was swollen(but I bought a new one so it doesn't matter). The day before he gave it to me, he accidentaly dropped it in the toilet and it couldn't boot. I opened the phone, cleaned it with alchohol and the phone booted up normally. The thing I noticed was that in the status bar the network symbol was replaced with No signal symbol. I tried 3 SIM cards and none worked. I decided to downgrade to 4.4.2 KitKat version and this is where everything went even worse. I used Odin to downgrade a firmware downloaded from sammobile.com, but I didn't create an /efs backup because I have flashed an Alcatel Idol 2 before and there were no problems with the IMEI or so. It turns out that Samsung devices are different and I am left with NO EFS BACKUP. I know, I should have checked what to do before flashing the device, but what's done is done. The device is doing everything great, there are no problems with Wi-Fi or Bluetooth either, except I cant connect to a network because IMEI is null/null and the Baseband is unknown. The thing is, I am not sure if the IMEI is wiped completely because of a hardware problem, or it's software related because of the /efs folder, because I am not a developer, but a civil engineer :silly:
2. Solutions I've tried so far :
- Flashed many different Android versions;
- Flashed a Lollypop with adonis.pit with Re-partition checked on Odin;
- Tried writing an IMEI and repairing the EFS with Octoplus box;
- Tried flashing an EFS backup from my friend's Galaxy S4 I9500 ( IT IS ILLEGAL IN MANY COUNTRIES, NOT IN MINE, BUT I WANTED TO TRY AND CHANGE THE IMEI LATER SO IT WOULD NOT BE A PROBLEM );
- Tried flashing with a IMEI_null_fix.tar.md5 file which i found on a forum and that didn't fix it either;
- Tried KIES to return the stock ROM but either it does not recognize my device, or it says that my device could not be initialized or so;
- Took the phone to service, but in my town the only service we have is not very professional and they didn't even know the IMEI null does not mean that I will have no wireless connection/bluetooth connection, so they didn't fix it either;
- Tried with EFS Pro, Terminal Emulator and programs similar to those, 3rd party and PlayStore ones;
- Maybe other things but I could not remember because I think I tried everything...
I don't know if the problem can be fixed, but deep inside me I hope that there is a solution, and I think this is the best place to search for help, because it is a great phone and I don't want to throw it away just like that.
Thanks in advance everyone, hope you can come up with a solution.

Anyone please ?
