Need help , weird problem on downgrade - Verizon LG G2

So long story short:
when i downgrade my phone to 4.2.2 , phone is not stable at all , it only works 20-30 seconds and then it restarts .
i tried both tot and kdz method , also did factory reset . but still same . phone only works on kitkat : official 24A/25A(newest firmware) , or some custom roms on kitkat . but JB doesn't work anymore .
some time ago it worked , but for now it doesn't .
So what should i do? i can't understand what's problem . should i try to do that on other computer or with other usb or whatever?
I need downgrade, because my cell radio is off on kitkat and i'm not getting signal at all , radio is disabled (can't figure out whats wrong with this)
maybe i have some hardware problem and it's not software?

[Q] My N1 always hangs

hi
I have got a Nexus ,just after i got it i unlocked and root it after it changed the Rom .
now it hangs most time for example when i plug the charger sometime it hangs and a big X with an open lock appears and i have no way else to remove the battery.
and some time when i use the GPS and navigation it restarts.
i have tried many Roms and Radios but even when i want to go to recovery it hangs too ,and sometimes no.
i tried to switch to ERD79 (fastboot commands)but i found out that when i finish it,still the radio Ver. is 4.06.00.12_7 .
when i change the Rom or radio it restarts and restarts and some time hangs again.
so please help me to solve this problem
thanks
Did you wipe the data?
yeah ,
every time i wiped data .
what's your version of Hboot and recovery?
HBOOT-0.35.0017
recovery Build RA-nexus-V1.8.0.1
really need help ,i can not use the phone .
it sounds like a hardware problem, but could you try a new ROM see if the problem is still there?
well ,last night i tried cyanogen 6.1 with radio 5.12.00.08 but still have problems.
how can i become sure about the hardware problem ?
is there any test or something like this ??
few days ago one of my friends told me to try RUU.
actually i don't know what is RUU and where i can find it.
i have searched for it and found some for desire but not for nexus.

Help Please ???

Thank you.
What custom ROM did you flash? and which baseband do you have?
now i installed MODACO Roms , i don't know what the baseband is , beacause there are many errors when the cell phone comes up like :
Process system is not responding.
or
the process android.process.acore has stopped unexpectedly.please try again.
or
the application calender storage(process com,android.providers.calender) has stopped unexpectedly.please try again.
these errors are in each custom rom and they get me angry , i don't know what the problem is , also the cell phone don't recognize SD Card and Internal SD Card.
please guide me to fix this problem
thank you so much
i'm waiting you , , ,
You shouldn't really try flashing custom ROMs until you know what you're doing and you're ready to take risk of even bricking your device for ever.
I can't post links yet but I'd suggest you to search google about how to flash stock ROM using Smartflash. Try youtube tutorial along with step-by-step guide. There's a very nice tutorial video by iPhoneIac. Google video search "smartflash optimus 2x"
Try custom ROM only after you learn how to flash correctly.
if you keep getting problems, you'd have to tell exactly the problems. If you can get stock installed alright, try remote call app, the folks over at LG can (or will try to) mend your cell

problem in WIFI

Hello .
I was changing the rooms of my device a lot lately , until I tried a JB room ,, the WIFI couldn't turn On ,,, i went back to the official GB room and the official ISC room ,, but the problem is still there ,,, when i turn it on ,,, it doesn't turn On !!!!!!
Some times it turns on for a little while then close it self ,,, and never work until it want to !!! i mean it works when it wants !!
Have you done a full wipe and clean installation? What is your kernel? You can also do a logcat and upload it here

Wifi Does not activate

Hi all
I have a GT-S6500 , initially it had the Branded Firmware AILD2 Italy TIM , after i installed the Firmware version XXLD2 and the Peter's Rom , everything has gone perfectly for several months until it went in bootloop.
So i installed the last firmware the XXLK2 ITA version , all works expect the wifi , at boot does not start and if i try to activate it says "Error the wifi cannot be activated ".
I reinstalled the last Branded Italy Tim firmware the AIMD3 , but it shows the same error , so i tried with XXLD2 ....same error :crying: , again I tried the XXLD2 and fater the XXLK2 with cyanogemod 10.1 , 10.2 and 11 but nothing changes.
Would you suggest any advice ? I do not Know how to do.:crying: , any info would be grateful .
Thanks Bye Bye
Sorry for my bad english
Any advice? :crying:
go back to stock rom and stock firmware , if you don't have a working wifi then = hardware problem.
keep it simple

Not entirely true on hardware problem. Might be a (config?) mismatch, I have encountered something similar as well.
When I went from stock to TheWhisp' CM11-nightly build.
After you've flashed a build (be it stock or TheWhisp' build), have you tried putting it back to factory settings in recovery yet?

Ofc he has to fac reset when he goes back to stock rom ..
I have the same problem with the squadzone OC kernel .. I will get this problem if I use the LK2E firmware series and the latest firmwares .. but It works perfectly with DXLD1 ..
just saying ..
it happens because you updated the kernel, it now has a slightly different version string which doesn't match the wifi module's, and it [the module] gets tainted (= cannot be loaded)

Is it possible to edit the Stockrom to be match with the kernel ??
you also need to updated the wifi module which is named ar6000.ko on gingerbread

no signal on 4.4.2 KitKat. what to do?

There is absolute no signal... On original ROM it says "turn off airplane mode" when I dial some number, but it's not in airplane mode.. Tried custom ROM, but there is no signs at all.
Before that I downgraded phone to 4.2.2 ( A1 and 10b version) and I got signal, but phone was not usable. It was crashing, it was freezing and so...
So any suggestions? Maybe there is some radio problem or what?
Thanks

Have you tried a new SIM from Verizon? If so and you're still under warranty, revert to stock and send that bad boy in for a replacement!

i'm not on verizon . i use it on different carrier (outside of usa) , but it was same on verizon . and it's not sim problem , because by downgrading phone to 4.2.2. it works , i can make calls,ect , but it was freezing and unstable . but when i update it to 4.4.2 there is no signal att all , the radio is disabled ..
I'm getting this error "to make a call turn off airplane mode" when i try to call
but it's not in airplane mode..
i read that not only me or not only verizon phones has this problem , it seems the problem is in kitkat , because i saw this problem on other devices too , samsung note 3, htc one or ect...
so , is there any solution about this?
once again , i've downgraded phone and it got signal , but soft was freezing , i think it's kernel problem or something like that . seems like it's not possibly to downgrade 100% to stock
i've flashed this

and now everything works
thanks to developer !!!
still same problem appeared . WTH?!
fixing permission in recovery and several restart (2-3 times at least) fixes problem , but it's not permanent fix , working until next restart (i think)
