L90 Phone issues - LG Optimus L90

So, I've got a hard task that I cant seem to figure out.
My phone sometimes will say "Invalid Card" When I look at the lockscreen and wont let me use Data.
I've got the L90 Variant and have NOT done the 2nd Lolipop Update which would remove my root access.
My Question is, If I were to flash stock Lolipop and update, would I be able to root anymore?
And If i dont have to, How Do i fix this problem?
My Phone will sometimes even get a Toast Notification saying that android.phone has crashed and then it wont connect to T-Mobile and say Invalid Card too.
Any help?

I would factory reset first (backup your data preferably using custom recovery to get a full backup) to make sure it's not a hardware issue.
You can root with Kingroot, I've used it with 20b and 20c, then used a script to replace it with SuperSU. Or install a custom ROM layer.

[Q] Please help, can't root to get back pictures

Hi guys, thanks for the forum and i hope to become a part of it. I've been under so much stress since yesterday, my galaxy s3 (on EE in the UK) for the first time decided it's data was corrupted yesterday after my battery died, never done this or anything like it before, and it wouldn't let me access the phone itself unless the data was reset.
I had a lot of very precious pictures in my gallery from the weekend, which unfortunately chose not to backup to google+ for the last few days, even though it always has up until recently. All night/day i've been trying to figure out and get software to recover these photos, which i think is possible as i did it a long time ago on a blackberry, but not android yet. I'm just hoping it can be done so the photos aren't forever lost, the other stuff gone doesn't bother me so much.
The guide i'm following (here: http://forum.xda-developers.com/gal...de-internal-memory-data-recovery-yes-t1994705) says it needs to be rooted first, and i can't even get past step 1. I've only ever rooted my old galaxy S1 (which worked back then) but i can't seem to get the S3 to do it. And now my phone also believes there's no sim card in and i get no signal now.
this is the guide i followed: http://www.ibtimes.com/how-root-sam...-jelly-bean-official-firmware-tutorial-975812
though i think i need a newer PDA file to flash my i9305 with. I'm on the EE network running 4.3 jelly. It installed Super SU but root checker says it still isn't rooted.
So have i messed this up? And is there any hope for me getting these pictures back?
Thanks in advance for any help, it's much appreciated.
if you are running on 4.3 then you are not following the right guide to root...
use THIS ONE instead... if it fails to root use the workaround part, i used it and worked....used the workaround to install custom recovery and then flashed chainfire zip from his website and updated SU and worked.
are you still able to boot the phone?
Thanks for the response, tried that guide and still getting no signal on my phone (no mobile connection at all, sim card isn't recognised as being there) and i don't think it's rooted right. Still saying SuperSU has stopped working when i try to open it.
I put the Root_SuperSU.1.02-Busybox.1.21.0.zip on the internal SD and tried that too.
Which is the chainfire zip you're talking about, could you possibly link it? I don't really get what you mean by custom recovery, do you mean it's the same as flashing the Busybox thing from recovery mode?
And yeah it still boots up normally...
use that tutorial to install a custom recovery...then install this SuperSU - http://download.chainfire.eu/396/SuperSU/UPDATE-SuperSU-v1.94.zip?retrieve_file=1 - flash it in custom recovery....after that update app with playstore and should work.
but i suggest you get it to a specialized shop to get your photos back...

[HELP] OTA KitKat update error on rooted D950

I have a (previously) rooted D950, and I can't get the OTA At&t update to install. I've completely removed root, and double checked through root checker that it's gone, and the update errors out every time with a message about having been rooted.
I read another thread where some people report being able to retain root after receiving the update THEN downgrading and rooting 4.2.2., then installing the OTA again, but it seems that I jumped the gun and rooted first, which is now causing the install to error out.
Has anyone else experienced this? Found a workaround? Ideas? Totally frustrating.

Here is the link to a detailed guide . Dev hyelton's page includes links to AT&T ROMs.
If you need help with LG Flash Tool:
- Connect your phone with usb to laptop/computer and open device manager
- seek for Ports: COM & LPT, right click onto Android LTE usb port connection, click "properties", click "Advanced", then change port number to number 41, click "OK"
- DOWNLOAD LG Flash Tool and install .exe
- DOWNLOAD MegaLock.zip (3kb), unzipped (7kb)
- Exchange MegaLock.dll in your system folder "LG" with the unzipped MegaLock.dll file that you have downloaded
- Open LG Flash Tool, input .dll file of downloaded stock rom.zip folder and input .tot file of this folder
- Click onto USB instead of LAN, then click "OK"
- Left arrow at the window top should be enlightened now
- Click onto this arrow
- Wait for all popup windows telling milky way download and connections to fail
- Wait then for the check of CRC and .dll files
- One or all ports should be opened, "READY" enlightened
- Disconnect your phone from computer
- Connect again and watch the immediate start of the flashing process
- After completion you must install most of the app updates, update your LG and/or AT&T profile before installing kitkat update.zip
If you'll stick in updating stock rom to kitkat, watch my video on YouTube (it's about LS995 Sprint, but AT&T LG Flex will proof the same installation process):
Visit my blog at http://www.myreviewsofreviews.for the detailed description how to avoid bootloop during the installation of LG Kitkat update.zip via ADB sideload
Thanks, but this is not a fix. Unfortunately, that guide is of no use since his links are still down. Further, I was hoping for feedback from others who have experienced this issue, and found a resolution. I have read that this is also happening on devices that have not been rooted.
I am not looking to flash a rom through FlashTool. I'm looking to fix the OTA error. All I want to do is install the OTA update.

Not sure what you were hoping for but the guide is correct process for your problem. You need to flash back to 4.2, don't touch anything in the way of modifying system files or deleting bloatware, sign into your main Google account, update all your apps...then root the phone and when it reboots look for the ota. I would give it a couple min to setup after flashing back to 4.2 so that it successfully finds the update rather than telling you you're on the most current software. I had your exact problem too, I was one of the first AT&T users on here to take the update I tried everything to
A: retain root with supersu features and some root cloaker programs etcetera
B: factory reset, call AT&T, to get them to push the update again because I just could not get it to successfully flash without detecting suspicion of root.
Flashing back to 4.2 to retain root worked for me over 4 times now on 3 different flex phones (I had some hardware and then software issues on my replacement model)

You say flash back to 4.2, but I am already on 4.2. Never left 4.2. That's the issue. The device is defective. They're sending me a new one.

You didn't understand my post at all it seems, I gave you the instructions to flash back to STOCK which would have fixed your problem. I did accidentally word my post incorrectly saying "flash BACK to 4.2" obviously I knew you were on 4.2, so clearly I meant use the aforementioned guide to flash back to stock then take the update. Looks like you went another route, congrats

Huh? Wut
Not sure where things went wrong here.....
Me thinks some thread cleaning is in order...
Stand-by....
Cleaning finished.
Come on folks, let's relax and take a breath. Sometimes things just don't work and there's little to be done about it. If common known procedures don't work, then hopefully something else will, and just move along to something else.
Or in this case, the device is being returned which of course solves all.
No need for anybody to get all bent out of shape, what started out as being helpful, just took a bad turn somewhere for unknown reasons.
Relax, be cool....

KitKat update on ATT G FLEX running on Tmobile.
This might be a stupid question . I have my ATT G FLEX D950 running on Tmobile. It is on Jellybean . I am unable to pull the Kitkat update and it says "Phone is not registered on network". I am assuming I need to get my phone on ATT network to pull the update. Am I right? is there any other way out ?

Kinda, yes.
I had the same problem. My phone was never activated on the ATT network so it would not recognize it. You have 2 options:
Get a prepaid sim from ATT, use it once and than put your Tmobile sim back in there or ask a friend that has ATT to use the sim for a few minutes. A text or a phone call is all you need.
Worked great for me.

[Fixed][Q] Is it possible to officially update to Lollipop on root ?

In the past, I have had updated a few times on root without facing a single problem, until yesterday, when I received the Lollipop update which weighs 776.73mb and stops updating in the very beginning before running into some error 0x11110000.
So, question is that is it possible to update ON ROOT ?
I know using SuperSU unroot one can't change the LG RCT check, but what's interesting is that after making a second attempt to update, IT STARTS ALL OVER AGAIN. I mean, downloading 776.73mb multiple times isn't going to reduce your data bills
Any ideas ?
Rooted. Stock ROM.
EDIT
Fixed it by performing a full 'unroot' inside of SuperSU and then using the LG PC Tool to update to Lollipop Well, I'm rather surprised that it worked when the same didn't work on the phone itself. So I'm guessing that the process used by the tool overrides all problems as long as the firmware remains stock.
Oh and I really didn't want to mess up that bad by taking the route suggested in that thread, @lfom, because I don't have an extra phone to fall back on, in case my current one fails to work
Modern SU tools also modify other system files, primarily to try to resist to updates... My bet that what is causing the problem is the same as this other thread (it offers a solution too):
http://forum.xda-developers.com/showpost.php?p=44913304&postcount=8
Actually , i updated my phone with root using LG tool, after update i lost my root but all apps where there, which means there is no need for unroot os something like that.

[Q] How to UN_ROOT (Kitkat)

Hi there. For over 3 monts I keep getting OTA infos about upgrading to lolipop. I'm currently on Kitkat and my phone is being rooted because of the xposed installer + titanium backup and tasker.
As there are gudes on how to ROOT, I don't find any on how to unroot if one has Kitkat version of android.
In order to upgrade via OTA to lolipop one has mentioned I need to unroot phone and uninstall xposed installer as it might alter some files that unrooted phone can't.
So can someone pretty please link me to the guide on how to unroot phone on Kitkat so I can safely upgrade to OTA to lolipol? Thank you in advance and I apologise because I didn't find any explicit guide on how to UN_ROOT.

Edit I just realised this should be posted under Q&A. Can someone move it there?

EDIT: I just realised this is second gen moto g forum :S I have first gen. Sorry for that :|
If you're rooted with SuperSU then from within the SuperSU app, go to settings, scroll down to near the bottom and you'll see the option for full unroot.

I did it just like you said. Application closed itself. And I when checking for root it says I'm not rooted. Problem is that when I select download update, it restarts phone and goes to stock recovery mode. Then there is a progress bar about upgrading but I allways receive error and then reboot and after phone boots I receive info about OTA not being successfull.
So my phone is not rooted (At least titnium backup says si). But I still can't OTA to lolipop :S
What are my options here?

Have you tried a factory reset?
Would be a good start to do a factory reset because just unrooting will probably not be enough for installing OTA. You have to revert all changes you did to the system like removing things like adaway (with restoring the original host file), unfreeze systemapps or reinstall them and so on . If OTA fails after removing all changes you did (or you can remember) you should flash stock kitkat rom.

LG Optimus L90 Root problems. HELP

Hello all. I Recently attempted rooting my phone, running on 5.0.2, and it seemed to have worked. But then after attempting to use SuperSU to add root permissions to an app, my screen went black, and the only thing visible was the top status bar, which had some animations still running (Like the battery icon filling up or the signal bars changing), but thats it. It wasn't responsive to any of my button presses, and then it shut off. It keeps doing this over and over, and i cant keep the phone on for more than 5 mins maybe 10. How would I fix this? I used this "tutorial". - andromods .com/news-root/lg-g3-g-flex-2-g2-lollipop-one-click.html - (Stupid thing wont let me post links)
I would like to solve this without factory resetting, as I have apps that have data on them that needs to be transferred from one phone to another, and i dont have a second phone to transfer to at the moment.
Thanks in advance.
As far as I know, flashing kdz with LG Flash Tool following the tutorial to "unroot" won't delete your data, but you will lose root, of course. If you don't have custom recovery nor root, there is little else you can do. Do you have adb root (shell)? If yes you can try re-flashing system partition...

I'm very new to this, and probably shouldnt have attempted this without knowing more, so I have no idea what you are asking me. What is ADB root (shell)? I probably dont have it. And I didnt do any sort of custom recovery. But it seems that me messing around with SuperSU (clicking the uninstall root/turning of superuser once or twice) seems to have stopped the crashing all together. Ive been using my phone since and it hasnt crashed. Whether or not that's fixed the real issue, I don't know. And I'm not sure I want to mess with it further. :crying:
