[Q] Wifi problem

Hello! I just bought this phone today and I've just managed to unlock the bootloader and install my first rom. However my wifi has been acting very weird. It works when using stock kernel and stock rom but hasn't worked on a single custom rom. I've tried a lot of them as well such as "xenon" and "pac". What is wrong here?

I'm a new user aswell, but I used other phones b4 and I recommend you to factory reset before Installing these roms (If they are not installed over stock rom), if you install them over stock ROM(which means the zip file DOESN'T format your /system partition) you should consider a factory reset after installation.
Before trying these, if ROM developer told you to use a specific kernel, try to flash that kernel back, I had some problems while installing some kernels and could never get my Wifi to work until I reflashed the kernel.
Take a nandroid backup to your external sd card before trying these, better safe then sorry

Maybe e reflash using the lastest original kdz firmware and going to alll the root - > CMW(now is oficial) - > install custom room should be the way.

Is this ALL Wi-Fi connections, or just a particular one that you are having trouble with? Is the Router set to use WEP? If so then you're out of luck as WEP has big problems, but as it is old technology you shouldn't really be using it anyway.

[Q] only boots into recovery

ive had the phone since at&t had it on display. rooted it and had various roms for the last couple years and never had any serious issues. last night i flashed jellycream v2 and then did a factory reset inside the rom. the phone prompted that it would reboot twice and that it was normal. it rebooted into twrp and did nothing afterwards. i rebooted it from the recovery and all it did was reboot back into recovery. i decided to flash a different version of twrp and still the same. then flashed clockwork and still got the same result. i wiped the bootloader and basically went through the rooting process again. flashed the latest version of twrp and the phone is still only booting into recovery.
i am at a loss because this is as far as my knowledge goes. its like the phone is stuck still trying to wait for that factory reset from the jellycream rom or something and it wont do anything else but load TWRP.

If factory hard reset will not work (with phone off, press power and volume up together for some seconds. You might want to try also holding home on the touch screen.) flashing firmware will fix it unless you have hardware failure, which I doubt.

Part 1 can be tricky, so take your time and get that right before proceeding.

so far i get the grey LG screen with 'booti mmc_read xxxx' at the upper left with the hard reset. it only takes 2 seconds to show up but the phone shuts off if i continue to hold the power and volume buttons. ill read up on that link here.

I missed that you wiped bootloader. You need that . So you could maybe just install the wkpark bootloader in recovery. You would do 1 and 3 here (1.25a file is down the page)
http://forum.xda-developers.com/showthread.php?p=39130435
I think Jellycream actually requires you have it, if I remember correctly.
Not sure why factory reset would cause that issue, but it will definitely not start without bootloader.
Flashing firmware will also write the (stock) bootloader if that does not do it. It will also reinstall the OS if system is corrupt or missing.

I can't find the thread for Jellycream2. Would you post a link? Are you sure it is for P920/P925 (same device, one is AT&T branded. I have the Thrill P925). If it is not for those device numbers, you may need xbsall's unbrick guide.
Also, if Jellycream2 is based on ICS and you were on a GB ROM, you would likely have needed to first upgrade to ICS and then install the ROM.
I'm just trying to understand why a factory reset could brick your phone...

ok basic rundown of what i did in the last year;
when first played around with rooted it about a year ago i used all-in-one to do it. i had already upgraded to ics using the lg mobile support tool prior to rooting. rooting went off fine until i installed a Beats Audio app from the play store. when the phone rebooted after it would be stuck at the grey LG logo. i didnt know what to do so i used twrp and wiped the whole phone. then i used all-in-one and flashed the ICS bootloader and did the flash kernel 4 fix or something its one of the last options to do. then using twrp i flashed ICS_V20_P20, Stock_V20P_Rooted, and a Thrill Update, the phone rebooted fine in an ICS rom but it ran like complete ****, so i tried various roms and the one i settled with was called OptimusRS V1. i used that up until 2 days ago when i flashed the jellycream rom.
after i factory reset that i tried to flash the different wkpark bootloader and twrp that came with the megatron tool hoping that would fix the issue. but it did so i reflashed the original twrp and ics bootloader from all-in-one.
failed to mention this before but i tried 3 different recovery files in between each attempt and it would flash and reboot fine but the phone would still do the same thing and just load recovery.
ill find links when i get off work today. thats the basic history of the phone though.

Hmm. Stil not sure then . Maybe a corrupt zip or you wiped something important. Flashing with LG Flashtool should recover it. And always make a Nandroid backup before installing anything from recovery.

http://forum.xda-developers.com/showthread.php?t=2392309
thats the jellycream rom.
im downloading the files for your xbsa rom at the moment. i do remember yesterday when i used the megatron tool i saw an option to flash the stock bootloader and recovery. i tried it but all i got was the pink LG logo then a security error message below it and the phone shut off.

Oh, ok, OptimusRS's ROM.
Hmm, I thought v20 was GB or something... If it is not ICS then that would be the problem. Also it does say there you need wkpark bootloader for that ROM.
Also, xbsall's v28B includes recovery but it is in system partition. I don't know if that ROM requires you install it from recovery partition or not.
If you still want Jellycream you should be able to flash xbsall's ICS v28B (the normal partitions one, not large partitions), then install wkpark bootloader 1.25a in recovery, then the ROM.

well that breaks down that a bit better. my progress at the moment is step f6. when i connect the phone nothing installs though. it just reconnects and disconnects every second or so. im guessing its because i already have those files. dunno though. i cant get my pc to install the adb drivers for the life of me when the phone is connected in recovery mode.it sees the new hardware just cant find the files.

actually i got it. for some reason the phone wouldnt install anything until i put the battery back in at that step. i continued successfully to step M. the phone is setting up my google account at the moment.
will flashing the baseband be necessary if my apn and sim work like the phone is now? my provider is h20(canadian i heard) but im the usa.
HUGE thanks regardless

Cool :thumbup::beer:
The no battery part is just for driver install, which is fiddly for this phone. Sometimes trial and error is a factor.
The baseband you have now would be the one you had previously. If it works, no problem. The one in the v28B pack is supposed to be optimized for the v28B .bin file, but hey, whatever works.

im only getting E for data. i tried to flash a baseband meant for at&t but it says failed after about 90 seconds. still no 4g though. i did flash the xbsav8 before i set my apn up. i might just go with an optimusRS rom again though. i was happy with it. probably not jellycream this time.

Baseband fail after 80 or so sec is normal. It means it worked. Check your baseband in android settings/about phone.
You might try speed test app to compare actual speed. ATT 4G icon is a lie on this phone IMO.
Now that your pc is set up you can flash any P925/920 bin. Kdz files (combo of bin and fls, there is another tool for flashing those files) can be extracted into separate bin and fls, but I have not done it. The advantage is you can flash baseband separately.
Xbsalls vX3D (see his page) with the P925G fls file gives me 4G icon on Straight Talk in the US, but I like his vR3D better, and I can't tell a speed difference, honestly.
I have not actually measured the speed in either, however.
And for either of those ROMs, you must flash his large partition version of v28B first...very important.

oh its definitely like 2g speeds. its pretty slow. i tried using my providers app and website and its saying the phone i have isnt registered to them anymore so it might be just that. if thats the case ill just bring it in so they can do that for me. when i rooted it the first time i wasnt getting any data and they had to re-register the phone to get it to work right.
my baseband says OMAPP4430/XMM6260. for comparison and/or confirm differences. i have no idea lol.
side question though; my sdcard still has recovery files for the optimusRS v1 rom i had on it. i really liked the setup i had when i made the recovery for it. Im tempted to reinstall it but im really not too sure if itll work or worse harm my phone again.

Lots of variables, but you must remember that xbsall's P940 recovery app he he uses has recovery in system partition. The recovery you had before was probably in recovery partition. They write restores from two different places. Probably you would get an error, but not positive. Understanding that may take some Googling...
If you try it, back up before trying to restore the old backup. Then you could hopefully restore if the restore fails, know what I mean?
Probably the safest thing is to use the all in one tool to install recovery in recovery partition and use that one to restore backup.
I do know when I have restored backups, I have wiped Dalvik, Cache, and Factory Reset (in recovery) and then restore. Then it works. Some people wipe system too.
You can usually flash to recover from a problem, but then you have to set your phone up again

Well I recovered everything. All settings and personalized stuff. Just everything. Everything is running normal again. Just now my data is saying im using an h20 microcell instead of just H20 with a 4g connection. This 2g stuff is for the birds. I'm almost thinking the firmware we flashed has something to do with it. The phone is functional though. Just slow and no mms. I haven't been able to find much on the forums about it. I'll poke around more tomorrow.
Sent from my LG-P920 using xda app-developers app

I'd try another baseband.

help Can anyone recommend a good rom for my wife

Can anyone please advise, my wifes xperia z recently received the ota update 4.3, which worked fine it seemed at first but we noticed the unability to tether to her laptop. my xperia t which is on the same network is fine. After various attemps to sort this out ie factory reset/ deleted some apps. I decided to repair using pc companion, which I did this morning, and guess what (no change?). I really didn't want to go down the same route as myself with custom roms but somehow this has left me with no other option. so I downloaded a 4.12 stock ftf and have flashed this using flashtool. And guess what, ( tethering is now working? ). I have now rooted and installed cwm, I have also downloaded dual recovery ver, 2.7.86. for locked bootloader to install to ext sd. Now am unsure which rom is suitable like stock as she is still new to her phone and still learning. I would appreciate any advise or comments. thanks in advance.

If.she likes stock try flashing stock 4.3 with full wipe you might had bad ota update
[email protected] Z

thanks, I thought this aswell. I have installed SuperHanss stock version, just in case she turns out to be a bit of a teckie

[Q] VERY worried about flashing miui rom and new bootloader.

I have just recently restarted using this phone due to my uscellular S4 getting turned off. I am now back on my LG-P990 currently rooted and running CM10.1. BUT most importantly to me is the fact that I have all my wonderful apps on my s4, I want to be able to use them by using the LG phone as a tether and calls not much else BUT CM10.1 tethering does not work, so i find myself flashing rom after rom, avatar rom, older CM mods, none would turn on tethering, so i flashed a modded version of MIUI for this phone and it worked except for ONE thing no signal, tethering turned on just fine so i decided to look around for other roms and found Slimrom TRYED to flash it didnt work, try to flash actual MIUI roms off there site, didnt work, met with an error in CWM Recovery after some searching I found its because Im running the OLD Bootloader -_- THIS is the issue im having IF MIUI does NOT work is it possible to downgrade the bootloader again so i can restore my CM10.1 backup? I have been working at this for a week, if there is something here about this can someone please just point me at it? I would appreciate any help.
On a side note i DID soft brick the phone the other day and found a program called nvflash witch flashed an install of CM mod. Dont know if that will help any.

I really do not understand how other ROMs deny Tethering. Did you flash the latest 2.x kernel by pengus77 after installing the rom? Did you make a clean install(wipe everything then install)? On the other hand, yes you can switch bootloaders as much as you like, just remember that changing the bootloader wipes everything on your internal memory, so do a backup. Did you try just plain old stock 4.0.4? Should work there. Ask anything you want, if you're still having questions.

As to the flashing to stock i lost the original rom backup i had made along time ago and cant find the original firmware anywhere online. When I flashed CM 10.1 I just ran with it, when i go to try tethering it says "Turning on portable wifi hotspot." and it stays on that no matter what untill i restart, left the phone running for 2 days once and that was still stuck on that before i restarted. As for flashing a 2.x kernel i had no idea about that. But yes when i did the installs i would do a clean wipe and install. Most of what i read online led me to believe that there was an error with CM 10.1 nightlys that was not being fixed for the tethering. So that is why i decided to go to another rom. Two questions one how do i go about finding the original firmware for this phone and two how would i go about updating or downgrading the bootloaders and could i be pointed to the files please?

Okay, This is SFSP by @sgspluss which is a pretty fast, stable and battery-friendly slimmed down version of stock ICS. It is available for both Old and NewBL, so you might want to try that first. This is AIO Toolkit. I know that you've used it and bricked your phone, but try again, and for the love of God install the nvflash drivers because most people skip that part. You have to do it manually and if you're running Windows 8 you need to disable Driver Signature Verification. But yeah, you switch bootloaders with this.

Stuck on 5.1.1 badly!

Hey guys,
So I wanted to upgrade to 5.1.1 and I saw a couple of ROMs for 5.1.1 that I was interested in flashing. So I chose this one > http://forum.xda-developers.com/z3-compact/development/rom-one-solution-debloated-xposed-t3164221
When I wiped, and then went to install it gave me an error, md5 error or something, but it seems it had already wiped my stuff.
So my phone was bricked and I could not get it past the initial Sony Xperia screen AT ALL. The only solution I found was to use "Emma" and recover it by resetting to factory. In doing so however, Emma installed a Stock 5.1.1, which booted no problems at all. Fantastic. Now I am on 5.1.1, unrooted, and inability to install or boot into a recovery to flash my backup.
Here's my problem, every single time I try to downgrade my Firmware back to Lollipop 5.0.2, or KitKat even, it either freezes at random places, like this > http://puu.sh/jRHEj/f3da0dfcfa.png
OR it finishes the flash on some Firmwares I have tried, but then I'll be stuck in a boot loop. I just cannot seem to have ANY luck trying to get my recovery back!
Any ideas what I could be doing wrong to get no success at all in downgrading from 5.1.1? Are there any methods to get into recovery in 5.1.1? Mine doesn't seem to ever work.
Is there a way to flash or install a backup that I did in TWRP without a recovery menu or no? Just want it all back to normal for now, 5.1.1 can get lost for the time being, screwed me over bad.

Try flashing the firmware ( ftfs ) using a different computer. If that doesn't help you can consider one of two options
1) Unlock your bootloader, that way all you need to do is download a custom kernel that comes with a recovery and flash any rom you like therefore removing the need for flashtool
2) Send your phone to Sony if you prefer not to unlock the bootloader and let them fix it but it might cost you
*Also take note if you downgrade to Lollipop ( 5.0.2 ) as I know there are no methods on how to root it yet unless coming from Firmware .93 which is a Kitkat firmware.

Hey Revo, thanks a lot for your reply dude. Appreciate you taking the time out of your day. I managed to flash a .93 kit kat, when I go to install TWRP via adb fastboot, my phone boots up with no image. I can hear sound and touch screen works but I have no picture. Super weird, had to reflash again to kitkat to restore picture. My bootloader is Unlocked already, so how effectively, on kitkat .93, can I get TWRP installed to recover my old backup? What's the easiest way from here?

If you have your bootloader unlocked, you can just flash custom kernel via Flashtool, that would be AndroPlus kernel and you'll have a custom recovery

Nice, got that done and just finished restoring my own backup, AHHHHHHHHHH my phone is back. Technology is freaky as hell man. Crazy crazy world we live in.
I really wish I could click one button and donate money evenly amongst all you insane people that write awesome awesome tutorials for what I assume is like, non-profit? It's mental. Wouldn't have my phone back right now if it wasn't for this forum. It's just unreal. SO happy right now.
So if anyone knows at all, million dollar question. What's now the safest possible option, if ANY, to get from 5.0.2 rooted, to 5.1.1 rooted? To keep all my data I am obviously going to have to backup up all my photos/music/contacts/sms etc onto my PC or online in a mysterious cloud, but what's the best steps now to safely get to 5.1.1 rooted, with no hassle? Or is it even worth it at this point?

Now you just have to download a prerooted 5.1.1 rom and flash it through recovery and that is all. Full wipe is recommended before that of course (data, cache, dalvik, system)
