[Q] No signal and unable to read battery - LG Optimus 2x

Ello
I rebooted my p990 yesterday and when it had restart there was no signal and the battery level was at 100% (even though it was only like 8% just before the reboot). Now the battery status is unknown, still no signal etc.
I've tried to clear cache/dalvik, I've tried re-installing the ROM, battery pulls, using a different battery...none of it has worked.
Anyone help me please?

Not like I can provide the solution to your problem, but you can help youself and anyone that is willing to help you if you provide more information about your phone... rom that you are using maybe.

Ah right sorry...I'm using temaseks 135.4 cm7 rom
I'm currently restoring a nandroid backup and seeing if that will bring back my battery/signal

Restoring the nandroid backup gave me back my signal/battery
Problem solved!

Battery stuck at 100%

Hi,
I updated my cm kang today and everything was working fine. I rebooted my phone and my battery percentage went from 4% to 100%. and it's stuck on it.
When i put the percentage mod of in CM7 i see a battery icon with "?" in it.
I tryed the following things:
Wipe data/factory reset
Wipe cache partition
Wipe Dalvik Cache
Wipe Battery Stats
Fix Permission
Installed a older kang but nothing worked.
I searched on google and some people fixed this problem by getting a new battery.
Has anybody else had this problem?
Thanks
100% without charging forever. its my dream
I've had the same problem. Check baseband and RIL. Try to use program "GetRIL" [market] and check is your baseband and RIL are the same. If not then you can download 'recomended' RIL and reboot.

Thanks, i restarted my phone and now the market is gone, baseband is unknown. A reinstall of the rom,and wiping everything,reinstall of baseband didn't work.
I'm gonna install the stock rom tommorow using smartflash. Hope that works

changes on IMEI ? *#06# ?
if you lost your IMEI try this LINK
Infinite power!!!!!
Baseband is always the same, no matter what rom you install BUT when you are changing a rom then "RIL" can change and that's why your problem was created after you install a new kang.
Now my baseband is 824 and its the best I've ever had. Good luck.

You have flashed a gb ril in cm7. Cm7 supports only froyo ril.
In fact if you don't do that, the rom is unable to read battery voltage and baseband version.

Don't think that is the problem because i have done that many times and it always worked fine. I found out today that i couldn't send sms, if i tryed i would loose my connection etc.
Restarted my phone and now it doesn't start anymore, it's in a boot cycle lol.
Gonna install stock rom now
hmmm.. i wouldnt actually change that it would be like a dream to have an all the time full battery

I repeat, CM is only compatible with froyo rils. Aremcee said that.

[Q] Problem with Slim ICS 3.5

Hi guys,
i have been using Krarvind's Slim ICS 3.5 for about 10 days and I absolutely loved it. I have just updated to 3.6 which caused my phone to bootloop
So, after an hour or so of labouring and trying to work my way back in to it i'm now back on 3.5, but I have absolutely no signal/3G coverage. Wi-Fi works no problems, just no signal!
I went in to the APNs and there is nothing there - I tried to save a new APN and it wont let me - has anyone encountered this before?
Thanks in advance
Haven't experienced this myself but a few things come to mind...
First would be to check if you imei number correct? If not you would need to restore this from a backup.
If IMEI number appears correct then I would try flashing the modem again or a different modem. Modems found here: http://forum.xda-developers.com/showthread.php?t=1158783
If this doesn't work you can try flashing 3.5 base and essentials again.
If that doesn't work search the threads and google or hope someone else can give you an answer. If you don't find any help then as a last resort you can flash a stock rom with Odin although I'm sure there must be an easier way.

I've had a similar problem, the updating to 3.6 just went wrong. No bootloop but loads of FC.
My solution has been going back to recovery, do a full wipe (wipe data/restore factory settings) and install 3.6 again. Everything seems to work now but I have to re-install and configure all my apps... :-(
Hope it helps...
Check in About > Phone
Under baseband does it say UNKNOWN ?
this happened to me once, need to reflash the modem. No need for wipes etc

Really need help with my fast draining phone!

A month ago I posted this thread: http://forum.xda-developers.com/showthread.php?t=1650113
And I still cannot fix the problem. I sent the phone back to repair but it didn't help at all! The repair description said that they did a 'software update'. It took about 3 weeks for my phone to return so I don't really want to do it again. Unless I really have to.
I have tried many stuff to fix this problem:
Bought 2 new batteries
Clean ROM install with NVFlash
Installed different basebands and rils
Formatted the batterystats
Tried different kernels and ROMs (custom and official)
Pulled out SIM/SD Card
Please does anybody know a solution for this problem? I really want my phone back!

Wow your battery drain (Screenshots from your first thread) is really huge. Let's try to solve that mystery together
But there is a chance that your phone really is faulty after all you tried already.
Please insert the original battery and fully charge it.
I don't use stock roms but think you should flash an official kdz first without any custom kernels. V20q or V20s (maybe with flix tweakpack). DONT use titanium backup etc, leave it stock.
You should install battery monitor widget by 3c to get information on your mV consumption.
In your Screenshot your reception wasn't good, please set it to "2g only" for now (or even consider to disable data totally and check how it behaves with wifi only).
Use your phone normally. How is your battery?

Thanks for responding.
I have tried to install the latest firmware with the LG update tool and the drainage was about the same. I did not install anything else on the device then.
Currently I am on the latest CM7 kang by temasek and baseband version v20s with 420 ril (also v20s daemon, I don't even know what this is).
I'll try battery monitor widget.
The reception at where I live is not so good even with 2g only. But I don't think that's the case becuase I tested with airplane mode activated and have also removed the SIM card.
Thanks again.
Just wanted to report that battery monitor widget is showing a power consumption of about -130 mA while on standby.
I think this is a very big number. And I think I had about -10 mA before this problem.

I had the v20s deamon installed too and I also had a pretty huge battery drain.
So my suggestion : remove it (by installing clean rom again).
As Tonyp already mentioned : try to install an original LG rom with it's default BB en RIL (use NVFlash to flash it). Don't use any other kernels or tweaks. Just the default.
Also don't restore anything (for instance with Titanium Backup or other program).
And set your phone to use 2G only, because a bad reception can indeed drain your battery (and fast too !), because it constantly seeks the network. Setting it to 2G only (it's mostly the strongest signal) can avoid battery drains.
And finally try to recalibrate your battery, there are tools available for that in the Google Play store.
Recalibrating the battery is a hoax. At least if you mean to wipe the battery stats (what most tools do). Real recalibrating would be to completely drain the battery (till the 2x turns of - not more! A completely empty li-ion battery would damage it!) and fully charge it again. But that doesn't improve the battery life, it will only improve the battery reading precisness.

Same results with stock based roms too?
CM roms are battery hungry
Yes, I got the same results on stock ROMs. I tried to 'cleanly' install the v10b firmware via NVFlash without installing else on my phone many times. And the problem still persist.

[Q] battery problem

i have a problem whit my battery...2-3 days ago i've installed the miui rom (also installed before) and it signal the battery ever at 100%...after that, believing that the problem is the rom, i tried cm 7.2 and the battery level isn't recognized...then i flash the v28e with bootloader unlocked and have the same problem of level battery (anyway recognised but not in perfect way)...what can i do? i tried the wipe battery stats and i'm not able to charge the phone off (i don't know why but it don't charge) ... thanks to everyone and sorry for my bad english
Format your phone wipe everything from system to dalvik and cache partition install fresh ROM..charge your phone when switched off ..if it fix than great otherwise go to customer care must be the port problem than
Try changing your baseband and RIL. That might work. Had a similar issue once and fixed it by doing that. Not sure if it's going to work but it's worth a try.

[Q] Help with GPS N7000 with Android Kit Kat

My Galaxy Note was with ROM SlimSaber 4.4.2 and the gps was not working. Then I put Cyanogenmod 11 but the problem continues.
Someone who has any of these two Rom is facing this problem?

Strange, I've formatted the Note, put the rom Slimsaber and Cyanogenmod 10.2 and gps still not working. I am using GPS Test and Sygic for try to capture the satellites but nothing happens.
Would know tell me a way to check if the gps is actually connected, and if there is any way to fix this?
Thank you for the help of the two.

Try install a stock Samsung rom and check GPS.
I have the same problem for a while. I am using SllimSaber.
I have formatted and reflashed KK several times nothing changed.
Now i will try stock rom as suggested.
I have installed AryaV7 nothing has changed, no GPS signal at all
Any ideas?

Does your phone's GPS indicator blink? Maybe your phone's GPS is broken? Have you tried aps named "GPS Test", from google play?
Did you tried to use the app GPSData to download latest AGPS info?
Also you can try to modify gps.conf/gps.xml to choose different time/supl server, that is greatly helpful for fixing GPS.
Try reflashing rom (clean install) - In case there is nothing wrong with your GPS hardware everything should work just fine
I have modified gps config data with Faster Gps. Results did not change.
I have also used AndroiTS Gps test,Gps data, Gps status, Gps essentials none of them was able to catch a satellite.
I have clean install Slim Saber but the result is the same.
I am started thinking that it is not software related.
It could be a hardware issue....
Folks,
Like you I spent days editing gps.conf, installing apps, reflashing ROMS, all to no avail.
There seems to be no magic bullet and what works for one may not work for another, but I eventually stumbled across http://forum.xda-developers.com/showthread.php?t=1973727.
As you will see it requires opening the case and 'tweaking' two contact points. To my surprise it worked for me - although not perfectly. I get about 10 satellite fixes and 6, maybe 7 locks. ('GPS Test' is an excellent freebie to tell you what locks/fixes you are getting.) But a big step in the right direction. There are a few images in the thread that describe the issue/ remedy.
Top (well, average) tips:
1. If you haven't taken a case off before:
a. don't try it just before setting off to a dinner party. It is a bit of a pig and requires some grunt, swearing and patience - but it can be done! There are a few YouTube videos that help explain the process.
b. you will require a size 000 cross-head (Phillips) screwdriver. Go out and buy one if necessary (if you can find somewhere that sells them - I use the one from my spectacles repair kit which just happens to fit; not perfect but does the job - http://www.poundland.co.uk/spectacle-repair-kit. If you try with too big a head you risk stripping the screw heads and that is ......... well, not recommended.
2. Once you have completed the job test your N7000 (with GPS Test) before putting the 9 screws back in. Mine works better with no screws! You may find different.
As I say above this may work for you and may not, so the usual health warning, proceed if you wish.
You can find similar issues on Samsung smartphones, eg http://gs3.wonderhowto.com/how-to/s...-gps-problems-your-samsung-galaxy-s3-0145332/.
Good luck :laugh:

Did you solve the problem? I have the same trouble that have arisen after updating to kitkat.I tried everything to solve it, without success (clean installation, downgrading to stock rom, editing the gps.conf file, reinstalling google maps, modem changes, hardware check ect.).
I switched to Lollipop but problem remain unsolved.
Regards
I'm glad I found this thread; I too have tried all possible solutions that may have worked for others (edit gps.config, reflash stock ROM, go back to GB, tighten the screws, bend the antenna contacts and so on), and none have helped. At all.
Now, I read somewhere that what is most likely causing the problem (completely dead gps, gps status apk shows zero satellites) is a corrupted EFS partition. This is a partition that usually is not touched by factory resets, ROM changes and so on. It also contains information that you cannot afford to loose (imei and so on).
So, I managed to backup this partition using KTools. Now, the problem is how do I get a clean, EFS partition? Is there a way to reflash this partition from a hidden backup thru odin? Or some other way?
Any help would be vastly appreciated!
Regards.
