I'm new in this topic, though I had a samsung galaxy ace before and and could root it without a problem, but oh, well.
Then, back to business.
I rooted my lg l9 768g after I bought it and delete some bloatware, but then software update showed up for JB. I downloaded the update and tried to install it, couldn't do it, after a reboot displayed a message saying something about my device being rooted and because of that it could not update. I unrooted the phone using the SuperSU app, instead of using the software I used to root it. After that I tried updating again to JB but the same error showed up.
Since I could not update to JB via sofware update, I tried rooting my phone again, but it would only reboot but the SuperSU app will not show up. Tried doing it several times with same results.

I used this program to root my phone, which worked the first time, but I can't make it to work again.
I tried flashing JB using this tread http://forum.xda-developers.com/showthread.php?p=36351786
but I end up with an error
I keep my phone in SW Upgrade Mode and connect the usb to my laptop to see if the drivers weren't installed properly but nothing installs.
So, I would like help with re-rooting my phone or help with another method for flashing JB other than the link already mentioned above.
Thanks in advance.
My phone is a Lg optimus l9 768g
android ver: 4.0.4
kernel ver: 3.0.21
Do you have CWM working?
Try flashing with Your l9 turned on normally and connect the usb in LG software mode (wait for the drivers to connect properly). Sometimes it doesn't work when you start out with it connected in S/W upgrade mode first.

Hi,
So I've got an xperia x10, and it was still running 1.6 so I wanted to upgrade it. So I went on the phone, selected software update (in settings -> about phone) and pressed update (didn't use any SE update tools on the PC). It started downloading the update, and after that it rebootet and started installing the update. At the last step however, this comes up:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
And this happens every time I try rebooting the phone, so I cannot start the phone.
Now I've tried several things:
- Repair phone using PC pc companion
Result: No update avaiable
- Update via SE update service
Result: You already have the newest software
- Flash via x10 flash tool ()
It says "Start flashing" but then nothing happens - seems like it doesn't
connect properly
It does seems like the phone boot into flashing mode when I try, at least the SE tools continues after I start the phone in flash mode (screen is just black but the green LED is on).
So is there anyway I can repair my phone? (I'm afraid I cannot go to a store and make them do it, I got the phone from previous workplace)
Thanks for any help!

Yes, still no luck.
Ok, I've installed all the drivers that come with flashboot (xperia u, flashboot and fastboot)
ST25i
firmware 6.1.1.B.1.54
ics 4.0.4
Says in the settings that it can be unlocked.
Gone all the way through the official method, at the end it just says "root failed" (rechecked both modes multiple times.
Installed flashtool, tried that method, root fails.
Run "root many android", also fails.
I am running everything in admin mode, the phone stays in fastboot and driver is recognized... I just have no idea.

better unock through flashtool
u trying to root or unlock bootloader??
I think he wants to root it...You have to flash .B.1.10 kernel as first. After that you can root (by any method, but I strongly recommend latest Flashtool). And after rooting flash back kernel B.1.54
Where do I get the kernel and how do I flash it? Thanks!
I've tried using this, but get the error "the device must be rooted 1st"
http://forum.xda-developers.com/showthread.php?t=1926387
Now following this guide, gets stuck when it tells me to unplug the device, hold the back button (up arrow) and plug in the usb, phone comes on, computer recognises, phone stays with blue led lit... nothing happens..
Use flashtool to flash stock kernel. Search for. 10 and. 54 kernels on forum
Sent from my Xperia Sola (XDA for Android)
Flash .10 kernel first. Root your phone with "root many android" trheads method and watch the tut vid. Then flash. 54 kernel. I couldnt find "root many android" topic with my phone, so just search for it. When using flashtool to flash kernels, first install drivers from drivers folder, then boot your phone in flashmode. Hope this helps

I held off updating my XZU to 4.3 until root was found, as I don't want to live without it (because of: Titanium backup, VPN software, full linux install on uSD card).
My XZU has an unlocked bootloader, too, as well as being rooted. I'd also modified /system/build.props too.
When I saw the OTA, I tried it and it failed without giving a reason, so I booted up Windows and used Sony PC Companion, and it too failed:

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I've looked at many XZU update threads and none seem to mention this specific issue.
When the tool runs, it takes a minute to "prepare" (it seems to have kept stuff it downloaded the first time). The phone does stuff, screen goes blank. Then the update fails giving the above message. The phone is then dead, and I have to unplug the USB before I can turn it on.
I restored the standard build.props from a backup copy. Do I need to relock the bootloader? Remove SuperSU and unroot?
Laptop computer has lots of free disk space, and is running standard win7pro-x64, nothing special installed.
thanks for any ideas.
I think that it is the unlocked bootloader?
I just flashed the ce 290 ftf when I had some error in pcc. Might have been the same one.
Rooting is easy on 290 if you have an unlocked bootloader
it's not root, because I unrooted device, so I am guessing its the unlocked bootloader. I've never managed to get Barclays Bank mobile app to work as it complains about phone being rooted, still doesn't work, so it must be detecting the system modified flag (this is using the older version of the app which was happy to run on a fully p0wned Galaxy Note 2).
OK, it was the unlocked bootloader. OTA update now working.
thanks!
So guys, Im new in this forum.
And just wanted to mention that Im a noob in programming.
I have a little issue with my phone. It is an iOcean X7 Elite with MT6589 progressor.
After getting bored with stock andriod I wanted to test the MIUI os and flashed it to my phone. It worked fine, but i didn't like the the rom that much and wanted to flash back to stock. I downloaded the stock rom for my Phone and flashed it with SP Flashtool. It finished without any error.
But the won't turn on. It wont even show the bootlogo. My PC does not recognize the Phone as a Phone.It says: Unknown USB device.
I have tried installing the drivers and used several flashtools (i case there is a version out there getting the job done).
Im really frustrated.
Last time I had a simmilar problem my phone showed the bootlogo and got stucked. But i got it to work by flashing. Now I have no idea what to do.
I'm already thankful for your help.
Was the backup your own?
Try to flash only the preloader, then if that goes thru you can do the full restore again... Come to think about it you might need diff drivers, or maybe meta mode (-vol and power)
I'm not at the computer atm sorry I can't be more help

Well it's being recognized so it's not a driver issue.
Is that your backup?
Do you have a backup?
Your not getting any errors?

Have no backup.
It just breaks up the process when reaching the 100% of the red bar.
From time to time I get the drivers issue error. Nothing more.
okay guys.
i tried an other stock rom version and now it says:
"BROM ERROR : S_FT_ENABLE_DRAM_FAIL (4032)"
Does anybody know what this means?
Thanks a lot for minding.
I think just do the full flash.
And DO NOT CONNECT your phone until the progress bar have passed the violet colored progress bar.
Hello there!
So I sold my S3 Mini and the buyer asked me to fix his phone. The first problem was that it was stuck in a bootloop and the EFS couldnt be mounted. I got that working and it now boots up normally. Now the problem is that I cant connect to my wifi and it says no service on my cellular. It detects my sim because when I booted it up it asked for the sim lock password.
Another problem is that my Windows wont detect the phone. But it's charging normally. It detected my previous S3 Mini before with no problem. I've even flashed CM11 on it then flash the stock firmware without any problems.
To clarify here are my problems :
1. Cant connect to wifi
2. No service
3. Windows wont detect the phone
The main reason I want it to detect to my phone is to use Odin to flash the stock firmware again. I've tried Mobile Odin but it kept saying to download and install the addons when I've already installed them. Mobile Odin v4.2 if you're wondering. I've also installed the drivers for everything and it wont detect. Thanks for your help.
Sounds like efs is corrupt, try another usb lead to connect to pc, shorter is better.

Any way to fix it? I got the wifi to work by flashing the stock firmware with Mobile Odin. My IMEI is also not correct.
Restore your efs backup.
