[Q] How to erase file from outside using ADB? - LG Optimus 4X HD

I have a P990 and a P880, both routed. In P990 installed CM10 Official, I liked the DSP Manager, so I installed the P880, but I realized that was not the same, so I copied the file libcyanogen-dsp.so to the / system / libs / SoundFX. After that restarted the P880, but now it just shows the LG logo and it does not come out. I know the problem is the "file-libcyanogen dsp.so" but do not know how to delete it. I am done with the clockworkmod recovery link http://forum.xda-developers.com/showthread.php?t=1826378 but when I start in recovery the system starts in original recovery mode and in the clockworkmod. Someone can tell me what can I do now? I do not know what commands to use at the prompt using adb to delete the problematic file.

I've solved the problem. It took the assistance P880 for an authorized LG here in São Paulo (Brazil) and they restored me to the original system. It took 1 hour and spent R$ 70 (US$ 33), is a hint to the Brazilians who want to put the system in PT-BR, this version is the V10C-2012-NOV-02. Now I O4X route again. I thank the moderators.

You spent money with no reason... to reset you could just flash the phone.
I thought you wanted to keep the files... apps... whatever.
The phone work with the PT-PT FW so good as with PT-BR and also accepts V10F without any issue.
Good that its working again.

Thanks RuedasLocas,
But in my case, I didn´t had access to write inside fone via ADB in Recovery Mode, at last I didn´t know how to do this. I installated CWM but when I had the problem (preeing Power Button and Vol Down) I just had access to original recovery, and It didn´t recognize the external SD, so I didn´t see another way. My former version was V10E, just in enghish it not was a problem for me.
To teel you the truth I´m waiting for JB + UI3, I´m really don´t care about LG Official update. I installated CM10 in my wife´s Optimus 2X, and It´s really nice.
Thanks Again,
Renato

You have to factory reset it, use R&D Test tool. And please, anyone having issues regarding anything, CM7, V20a, flashing, etc. post on dedicated threads instead making one. 'Cause this was solved earlier on those threads. Unless a new issue arises...

I am sorry that i dont know what R&D test tool is. I saw that the related thread have very few response that seems to have no help on that.
Moreover, I need to recover my phone ASAP since I just have this phone for my daily work.

Yes, I did try this method but doesnt help at all.
after 100%, it has a reboot, showing LG logo; then reboot, showing LG logo once again.
then, since the third reboot, however, it turns to a black screen and flashing light of the 4 buttons; and have this loop forever and no LG logo again.
sorry for my poor english.

Try this one. It was also posted there. If you managed to unbrick it by his method, reflash again then with your V10b HK. Don't forget CS_EMERGENCY mode. or with CS_EMERGENCY, Try direct V10b flash. Trial and error.

Actually ...i love XDA tearing my phone to every single bit..learning how to edit roms and everything and testing on my own phone (coz i know how to unbrick nw ) hahahahaha...its fun...

can someone help? i think i have bricked my optimus x2

Hi everyone,
My x2 is a vodafone, imei unlocked, stock 2.2 and CWM.
Im in the USA now and im using an iphone here so i wanted to update the x2 while not using it.
I read that lg will update trhe x2 to ICS and i had a pending update on my phone which i couldnt install due to a CWM.. Thinking it might be the ICS i went ahead and removed the CWM.
I removed CWM with "r1-stockrecovery-2x-unsigned", This did allowed me to boot into stock recovery. backed up all my data, did a factory reset and looked for update via wifi.
it found the update, downloaded (it was a small file, so no ics i assume), rebooted it self to install the update and thats it.
Now it boots to the LG logo and it stays there.
power Vol- goes to recovery for a brief moment (15 secs or so) and then back to LG logo.
What i have tryed so far to no avail: http://forum.xda-developers.com/showthread.php?t=1457582&page=2
Uninstalled all LG drivers and software from system, W7 64 bit.
I have downloaded 2x-nvflashdrivers and 2x-v10b-1300166062-nvflash
My comp detects the phone while in recovery mode, but wont take those drivers, hence NVflash cant detect the phone.. Once the phone goes out of recovery more my comp no longer sees the phone as connected.
I know its a lot to read but wanted to clarify in detail as much as i could so we all are in the same page.
UNBRICKED P990 - optimus X2
FIXED!!!
Thanks to a guy on you tube for directions, seach for user "iPhoneIac" tittle "LG Optimus 2x - How to flash to stock rom"
Program used:
SmartFlash P990
SmartFlash drivers, if u see modem driver not working under windows try to do the flash anyways.
Youll need ISO and FLS file as well. I found an open european set.
i can post links but im not sure if its allowed here, if it is let me know and ill post them so others can benefit from it.
Now that i got the phone working i can keep experimenting, i know how to unbrick it now

[Q] LG Optimus 4x HD gets stuck on boot animation,please help

Hi All,
Sorry if this is a duplicate but everything I have seen at least has not helped me further.
I wanted to root my phone yesterday and everything (tutorial here with o4xr) the went well till it installed busy box where the computer froze and then shut itself down and so I tried to turn restart my phone normally. Now its stuck at the bit where the LG animation is and goes no further.
Here is what I have already tried:
Rerunning the o4xr/root method again
Hard Resetting (selected and running all options available)
LG Service App (windows) -> always fails on communicating with device... works up until that and I do see the SW Ugrade splash.
My version is the EURO Open v10h or something like that.
Please help me fix... This is the first phone I havent been able to root, any suggestions?

Not hard brick, but soft brick. There is a huge difference. Just for your info.
from where can I download .kdz file and the main site is telling
ACCESS DENIED
http://csmgdl.lgmobile.com/swdata/WDLSW/LGP880/AAREBK/V10b_00/V10B_00.kdz
is there any other links for the .KDZ file to be download from

[Q] Reboot serious problem

Hi friends, since 1 month ago every time that I reboot my my O4x this one lost all information, for example, If I unistall a aplication, take photos, etc etc everything I do, I lost when I reboot it and I can`t enter to recovery mode. I have installed vanir rom 4.3.1. I tried flash a stock rom, but doesn`t work. I`ve been reading all thread but looks like anybody had have my problem. I appreciate if someone help me, I been trying everything , but nothing works.
What do you mean with "I tried flash a stock rom, but doesn`t work"
What error do you get? Why can't you enter recovery? Which recovery?
What was the last thing you did before this problem appeared?

I mean, I tried flash a lot of roms but no ones works, the installation always stoped in the same place, and I finally could installed completely a rom (V10A) but when my device reboot after installation, I realize that doesn`t work, my 04x still has vanir room =( .I tried to enter in recovery mode pressing vol- + power, rebooting in recovery mode in vanir power off option and via ADB, but no ones works. I had installed CWM recovery.
The last thing that I remember was installed lucky patcher to patch poweramp. I tried to unistalled it but when I reboot my devices, this one appears again. My devices works, but a lot of apps stop working while I use the phone, like line, whatsapp, swiftkey, google app, wifi and camera doesn`t works, or work sometimes, I lost all sms, missed calls, chats conversation, etc etc when I reboot my devices, is a pain in ass =(, I hope you can help me to fix it, regards!
It sounds like your whole internal partition is set to only read and not write....
You should try to flash stock kdz using the lg support tool (not flashing through recovery)

What's the problem with flashing process using mobile support tool? What errors do you get? Btw use the official mobile support tool, not the ones you download to flash custom KDZ files (such as older versions)

I just try to upgrade software by lg mobile sopport tool, but the installation stopped at 21% and say "upgrade stopped due to an error".
I bought my o4x online, and I live in Australia now, and the problem is that this mobile doesn`t exits here, so when I have to choose a country and a language I don`t know what is the properly one, I choose hong kong because my phone is from hong kong, What language I should choose?, cheers.

Well try the unbricking guides on the internet.Flashing process using unbricking steps might be able to help you fix the issues with internal storage.Check the third post on this thread for example, the same thing happens with them.Flashing process stops at 21%.Maybe your phone is bricked in a weird way that it can boot but can't write to internal storage due to software errors.

I had bricked my phone once, used that exe mentioned in OP and it worked for me.Good luck

I had this problem like 5 months ago
OK read this and follow the exact guide im doing it personally so that you dont have to search! kk
(for getting your phone working)
1.install the phone drivers from the website ( it might show on the com port thingy then )
2. flash only a gingerbread rom or froyo rom because the ICS rom is locked with a bootloader and will cause the lg logo thing all over again if you flash
3.From this link download the gingerbread rom( download the V20A from venezuela )( http://lg-phone-firmware.com/index.php?id_mod=1 )then use the rom convertor ( go to this link for the guide on how to flash http://forum.xda-developers.com/showthread.php?t=2144577 )
4. if it works, all you have to do is put a rom on your sd and go on with your life
( PS I suggest you try HUEXXX's IZS ROM or Marvel V9 as they both are really stable and works really well)
as for other roms
Dont forget to click the thank button on the corner of this post

causes permanent brick if not done well ( i think )
your not detecting problems could be anything!
try reinstalling the drivers all over again
or try another computer!
and also the USB CABLE you are using should be lg ones
and if any lg ones dont work use your OB CABLE!!

Tried reinstalling drivers about 20 times;
Tried on another computer still the same;
Tried other (not LG) cable still the same
Today I was at local service center, they said that they cant fix it, so they sent my phone to a better service and they have some kind of box mobile phone fixing tool. Looking forward, that costs 10 to 15 euros. hopefully they fix it.
