Hello all
Im new to the world of LG, already owning Samsungs Galaxy phones, I'm familiar with 'Rooting, Odin, Reset Flash Counts,Roms etc'
So the LG Optimus 2X LGP990 Star I have is Android based and is currently running on:
Ginger Bread V 2.3.4
Baseband 1035.21
Kernel 2.6.32
Build Number GRJ22
LGE Version LGP990-V20I
So then the questions are:
Is there an alternative program to Odin ?
Is there a program similar to Samsung kies ?
Is there a recovery mode / download mode key config ?
Is there a 'firmware site' like 'sammobile' to download firmware from ?
Does ICS 4.0.x exist for this phone, if yes how can I install it?
I've been to the LG software support section and installed the Win Drivers and the support tool and thats about it for support.
It says the phone is at the latest version - V20L
So many thanks for reading and hope fully some one will be able to point me in the right direction.
:good::good:
Root the phone,install Rom Manager,open it and from its menu install Clockworkmod recovery which is the main tool u need for rom flashing.
Theres no ics sadly,we wait for it.

you mean alternative for pc suit???
Alternative for LG PC suit is "my phone explorer", Google it. And firm ware is NV flash tool for installation of recovery mode "Do no use any app for installing CWM " you can get this tools by browsing xda in 2x forums.
I can not paste direct links,I am typing this message from my 2x.
And there will be an official update released soon.
Thank you.
Thats great to hear a possible ICS rom, hopefully official.
I'm surprised there wasn't one for this phone before the Samsung Galaxy Range.
Comparing the speed / responsiveness of the LG Optimus phone and the Samsung Galaxy S2 / Note - I'd say the speed of the optimus is far quicker and responsive - it's a nifty little phone :good:
There's another thead in this section on rooting the LGP 990 for the 1st time, just read it and the principles are the same as for the Galaxy S2 or Note.
So basically I use 'super one click 2.3.2' - probably an exe file for the pc?
I have CWM apk app installer I downloaded and kept for my Samsung phones - yes it works ok
But alternatively, I install:
1) Rom manager 1st - which then gives me the option to install CWM from within it
2) Boot into CWM recovery mode from that option in Rom Manager
No odin though, install rom image as a zip file from the ext / int sd card.
I notice there are no 'safe / unstable kernels to flash prior to and post rooting the LGP990?
I presume whatever rom I install, will erase / wipe over the original template already in the phone?
What is the best rom to install on the LGP990 at the minute, or is it worth just waiting for the ICS rom?
Cheers for the help :good:
The main advantage of the O2X as a dev phone, in my opinion, is that it is almost impossible to brick it, with the possible (but I didn't ever encounter it) exception of a failed baseband flash. It is really fool proof to root, no unsafe boot images or bootloaders to flash, simply run any known "hack" and you will end up with root.
There are many ways you can get into the custom ROM game. The easiest one was already mentioned: Root with SuperOneClick => ROM Manager => Flash CWM => boot into recovery from ROM Manager or by turning on the phone with power and Volume Down button pressed.
An alternative would be to use the script provided by Paul O Brien over at modaco which gives you a CWM installation without rooting or using ROM Manager.
Stock ROMs are available as .kdz files and pre rooted CWM images here in the dev section, enabling you to use NVFlash/Smartflash with the former and CWM with the latter to return your phone to a stock state. I suggest staying away from flashing basebands unless you have a specific problem you aim to solve with another baseband, our CM maintainer hasn't changed his baseband ever, and he (like me) uses the oldest version known to this forum. Whenever you flash a ROM, make sure your Baseband matches your RIL file, which can be done easily with the GetRIL app from the Play Store.
ICS ROMs to date are sort of hit and miss. I used owains builds, Nova HD and currently Paranoid Android. If you are fine with a glitchy Phone that might simply restart itself randomly once you open any app from time to time, can't record/play hardware accelerated video due to missing drivers or slow down if you haven't rebooted for a while you can flash away.
If you're comfortable with the Gingerbread builds atm I suggest flashing the latest CM7 RC or Nightly and wait for the official ICS update which will hopefully arrive in the next 2-3 months.

that's nifty nice quick cool understandable first info. thanks a lot. (I knew that already by searching way a lot more topics than it could be, but your summary is cool. Thanks again.)

have you solved this already?
I believe that you should go there http://forum.xda-developers.com/showthread.php?t=2020737 :fingers-crossed:
I have been reading this website and several others over the last few days and last night decided to give rooting a go. Trouble is - I am not sure where to begin.
Last night I tried downloading Philz kernel - PhilZ-cwm6-DXLR5-OLB-v2.7 since my kernel version is 3.0.15-n7000dxlr5-cl968032.
I then followed these instructions:
Download xxx-signed.zip kernel matching your ROM
Put the previously downloaded xxx-signed.zip file on your external sd card
Boot into stock recovery (volume up+home+power)
Select "apply update from external storage".
Now select the xxx-signed.zip file you copied in previous step
You are rooted + new PhilZ-cwm6 kernel with CWM6
What I got was a message like - signature authorization failed.
Not sure what to do next and would appreciate some guidance.
I am doing this basically because Ive decided to keep this phone a little longer, learn about rooting and try my hand at experimenting some of the custom roms.
Again appreciate any assistance / guidance anyone might be willing to provide
thank you
Is this the one you tried?
http://d-h.st/o9X
yes... i think that is it
download using phone browser. the move it to ext sd and try again..
case sensitive link.... my bad
Obviously Not. The link i posted links to the kernel. It should be downloading the kernel.
same result..... signature verification failed
The otherday I use PhilZ 3.99 for LR5 from his thread in ori dev. It works fine.

Sent from my phone.
Like I said... im new to this, but the instructions seem simple enough (as above). Wish I could get it to work for me....
I saw you are using ver 2.7. On the PhilZ he has 3.99 for lr5. It worked for me.
Sent from my phone.
i am downloading the 3.99 version now - see how it goes
tried 3.99 and get the same result -- signature verification failed
Strange. Maybe check if there a box in the stock recovery that can be ticked or unticked? Otherwise, check other root method from dr.ketan sticky at android dev thread. Many easy method, even an apk that root.
Sent from my phone.
dont know if this is relevant to the issue, but here it goes
About a month ago, I let the phone update some software - didnt really pay attention what it was updating as i was working.
Later that day i noticed my company email was not coming through. I raised a ticket with IT and received a response after looking into my case stating that the company does not allow rooted devices to access the email system. I found this strange because I had never tried to root the device. Is it possible that somehow an update occurred that rooted my phone?
Im aware that there are several ways to root, but again, im new to this would appreciate further guidance that might help me get this phone rooted.
thanks again
I would try method 0 and 1B from dr.ketan thread below.
http://forum.xda-developers.com/showthread.php?p=18978158
Let us know how it goes.
Sent from my phone.
willing to try these methods - if i start with method 0, how do i go about flashing with a safe kernel?
i have read quite a bit about kernel issues for 4.0.4 so just dont want to create a serious issue

once rooted, use mobile odin to flash tar.md5 version of philz kernel, not zip
ok.... im rooted - thanks to both of you for the assistance.
now.... im rooted at 4.0.4. If i want to install a custom rom say for 4.2 or 4.3, I guess I need to root to the appropriate operating system. how does this process work? do i need to first flash to a safe kernel?
bear with me.... this is very complicated for my non-IT brain : )
The most reliable roms now are still stockbased custom roms 4.12. Other newer roms are still experimental. I like Sweet rom 10.5. You need to read instructions for rom flashing from the rom thread.
Sent from my phone.
i have downloaded the following files to computer and getting ready to place them on my phone:
PhilZ-cwm6-DXLR5-OLB-3.99.tar.md5
MobileODIN_FlashKernel_N7000-v3.0
MobileODINLite-v3.85.apk
Is there any special instructions i need to be aware of for mobile odin? I assume i just run the apk program and follow instructions from there to get my safe kernel flashed?
i9305 Imei shows null/null after flashing I9305XXUFNL1_DBTFNL1 which was a stock rom
Also no signal as you would guess
Now I cant even downgrade to any roms apart from 4.4.4.
Phoen is rooted and tried 4.1.1. I9305XXALI5_I9305EVRALI5_I9305BVALI5 through Odin and Mobile ODIN
On Mobile odin phone looks like its working then stays on the SAMSUNG Logo for ages and nothing, just stays there
I have a Back up of an efs which I done through Rom Manager but not sure if its corrupted or how to restore it
If someone coud give me a walkthrough :highfive:

Hi,
About IMEI null/null with 4.4.4 firmware, you should search in this Q/A forum, there a lot of threads asking for this issue. Maybe you should get an answer yourself
However, you should try again to do a clean flash of latest official 4.4.4 firmware with ODIN v3.09 by following this GUIDE HERE from @MaHo_66.
AFAIK, it's impossible to downgrade from 4.4.4 because of KNOX bootloader. It has been said many times in this Q/A forum. Maybe it exists somewhere a tricky trick to do it but I'm not aware of this.

In Addition to @FLooDW 's answer:
Try to use Philz 6.48.4 or 6.59.0 as your recovery rather then TWRP or the old CWM (6.0.4.7), especially DON'T use the latest TWRP from their official website, its a broken build and its known to mess up the partitions! That could be your problem if you have done that before...
Any recovery you want to use, download from my RECOVERY/GUIDE thread that FLooDW linked to you, use those they work fine.
PS. before flashing official firmware with ODIN, make sure you have a custom recovery installed, then boot into recovery, wipe system/data/cache/dalvik-cache/internalSD/boot/modem etc. this is to ensure when you have flashed the firmware, there is nothing left from the previous firmware that was installed.
Note: when explaining your issue, try to do that by providing as much as possible info about your actions before and after the problem occured, that way anyone who wants to help can help you the best way possible.

Really helpful addition !
Trying what you guys have mentioned just now, let you know as soon as :good:
What 4.4.4. om do you suggest?
Also the efs I backed up (not sure if its working or not as it was with Rom Manager)
How do I restore, can it be done with root explorer?
Tried the [ROM][i9305][18.10.15]>>>4.4.4<<<[KK][STOCK][TW][STABLE][+AROMA] S5 Elite Lite v4.0
which I posted a few days ago, left a post with no reply and thats when I started getting the null/null
PSN_AGNi_pureSTOCK-v5.9.5-4.4.x_I9305_AROMA
Currently trying this rom.. watching the installation set up and says so far that set_perm: some changes failed
used philz_touch_6.59.0-i9305
Rebooting and stays on Samsung Galaxy boot screen ??

AGNi is not a ROM, this is a kernel. Did you flash AGNi kernel over official Samsung firmware ?
As MaHo_66 said, you have to explain more what you have done and what you need if you want us to help you.
Steps :
reflashed a Stock Rom then Rooted it then added Philz Recovery
Then Tried this rom : I9305XXUFNL1_O2UFOB1_4.4.4_KK.zip
Currently trying various modems to see what this gives me
Failing this will need to try QPTS or EFS Professional again.
* I know how to flash and root roms if you look at my signature along with kernels I am basically telling you what I have tried to get
this null/null away as I think its a baseband/modem issue somewhere as I have read various posts and some people agree.
Cant even do the *#197328640# or *#*#197328640#*#* to get into certain modes
Thinking it maybe the sim card slot now .......... I am losing my mind now!

There are few other possible solutions you could try:
- try this, it shows you how to get in service mode and the restoring of the golden efs backup, that should be present if its good.
If above doesnt work, then try the one below.
- have you tried to flash the param_bin file? if not try that with ODIN, it might work.. file attached.
Let us know how it goes.
H yes tied that file and didnt work
will the imei work from another phone or efs?
isnt that link just gps?
Since I found them particularly difficult to obtain and use successfully with my S5, I've put together a few PITs and the right firmware for the Galaxy S5 G901F LTE/4G Plus model.
I know it's a fairly old model now, but I just thought I'd help some people out considering most websites offering these files are very slow, or no longer support it.
Note: I'm not responsible for anything that goes wrong with your device. Be careful and make sure that you follow trusted tutorials or guides on how to flash your phone.

- Please tell me if I've done anything wrong with the packaging of the files. I'm new, but I thought I should provide easy access to some last-resort options in case people were in trouble.
These files can be particularly useful when you've got your phone into a state of not booting up at all, and only allowing you to boot into Download Mode.
You can flash both of these with ODIN, however the latest version never seemed to work for me, so I suggest first trying the new version here, then the older 3.09:

Hi, i'm new here and to flashing roms etc. so.... Sorry for my noob behaviour but are those links you provided here (firmware + pit file/s ) still available anywhere. I've searched endlessly (it seems) to find firmware for...
Samsung S5 plus (SM-G901F) ... (( EE UK-- i think)) ... Successfully flash several roms but the phone remains stuck in boot loop after Odin 'Pass' on almost every rom ive tried.. . T
The only thing that works is Odin mode so far . After every odin flash same thing... boot loop and cant get into recovery to factory reset.... Any advice or tips so very much appreciated . Thanks.
alcatron
Any chance to share those files again please?
I have an old S5 Plus (SM-G901F) which doesn’t boot.
I have found my old Exhibit 4g and want to give it some sort of use but unfortunately it has no OS and I can't get Odin or Windows to recognize the phone when it's in download mode. I'm able to enter TWRP but I can't find a single rom... please share a working link if you still have one. Thanks in advance.
You should be able to flash the stock ROM (uvlg3.flash2stock.zip) from TWRP. For something newer, there are some CyanogenMod ROM downloads on posts 2 and 3 which are still live.
