[Q] SGS: I9000 Poor Wifi 4.2.1 - Galaxy S I9000 Q&A, Help & Troubleshooting

Hey I was hoping someone could help shed some light on my wifi signal issue or guide me on a method to fix it. I use my wifi from my bedroom and my modem is downstairs. As soon as I changed to the below setup I continually received frequent drop outs and latency issues using VoIP apps such as Viber. I am happy to downgrade firmware if I need to but am unsure to what level.
Anyway sorry for the long details but I would rather be thorough as I am pretty unsure when it comes to a lot of this, thanks in advance!
I was running a JVR 2.3 firmware and I had to update with CF-Root-XX_OXA_JVR-v4.1-CWM3RFS (TAR file) which I did using Odin 3 ver 1.3. It took about three attempts of getting the phone caution pc sign as it kept crashing but it eventually loaded and it was finally rooted. So I dragged galaxysmtd_aosp_jb42_20121209 and gapps-jb-20121212-signed to the root folder. Booted my phone in recovery mode and did a complete wipe and installed both of the above files using CMW.
It all boots up now now with the Cyanogen intro etc and the phone's details are GT-I9000 running Android 4.2.1, baseband version I9000XXJVT, kernel version [email protected] #33, build number full_galaxysmtd-userdebug 4.2.1 JOP40Deng.pawitp.20121209.120851 test-keys.
I did some research and made sure the box was unchecked so it would allow weak wifi connections.
I also downloaded an app called Devil Kernel Manager which has a misc option to change wifi connection from power saver mode to stronger however it doesnt appear to do anything and I get the error message:
>echo 1 > /sys/module/bcmdhd/parameteres/uiFastWifi &&echo 1> /data/local/devil/wifi
[sh: <stdin>[1]: can't create /sys/module/bcmdhd/parameteres/uiFastWifi: No such file or directory, 1]

[Q] Loss of Network Service

I have the SGS GT-I9000M from Bell, was running Froyo 2.2
Decided today to dabble around with rooting and roms.
Followed all the directions to installed Darky's v9.2 Extreme Edition w/ Voodoo 5.4.1 kernel.
Everything went flawlessly and everything runs slick. Except for one small issue.
Now I seem to be losing network connectivity. Sometimes it will remain on "Bell", other times it will just display "No Service" or "Emergency Calls Only".
Have I missed something or done something incorrectly?
Any insight on this would be great.
Thanks in advance.
Also, is there a way to revert back to stock 2.2 if necessary?
Revert to stock via Odin
Darky problems check Darkys posts and FAQS .
jje
Tried and failed.
Went through every Darky's post I could find and can't seem to see anything like this being mentioned.
I even tried the Resurrection version, now my phone is a brick.
Does nothing but reboot over and over at the start.
Can't get into Recovery, only Download mode..
Suggestions?
Go to sam firmware.com download the android version 2.1 update 1 ughj2 or whatever its called. when its done downloading put your phone in download mode but first open up odin. select 512 pit and check repartion. Choose the firmware as pda and connect your phone to the computer and press start wait until odin finish flashing it and comeback and tell us what happened
I was able to get the phone working again, pretty much what you just said.. but with 2.2
Only issue is now I have no data network connectivity.
Zero options for it in the settings, and I've even called my cell provider..
They keep telling me to wait a few minutes and it will reconnect..
It's been a few hours..

[Q] HELP! Wifi issues!!!

I have Motorola XT701 (Milestone,Motoroi or whatever) and I flashed a sbf and the wifi has very good signal but I don't have the android market. If I try to root and install a much better rom with market the wifi signal is very weak. I tried to open the sbf and the CG39.smg (system image) and replaced the app folder in there but when I compile the new sbf I can't flashed because the RSD is giving checksum errors! I had installed even CM7 wich is great at speed and market is present but the wifi has very weak signal. In all roms I had this problem maybe because most of them are for the milestone A853 or A953 or whatever? Should I edit a specific CGxx.smg? The wifi signal is the only problem I have after I root, but I like the phone very much!
Wrong device forum, but I'll help ya.
Install your SBF that's missing the market. Don't modify it.
Once you're up and running, go into your recovery and install the gapps.zip that matches your Android version (gb, ics, etc.) as an update. It will add the Google apps to your ROM's read-only filesystem. (This is done on the device, not from the PC.)
If that doesn't work, you could always just look for a com.android.vending APK....
thanks for the answer, but the problem is the wifi. why is the signal so low now, after 5 months from when i baught the phone?!?!
Maybe problem with indicator
I have seen this in many ROMs. In some ROMs the indicator shows low signal even when the signal strength is just fine. Are you having trouble browsing or downloading stuff?
yes. the wifi is 2lines of 4 at half of meter from the router. at 2 metters is 1/4 lines. do i have to flash something additional besides the sbf for the android or the sbf for cm 7?

You can set static IP with the built-in Settings app(Wireless & networks, Wi-Fi
settings, menu key, Advanced).
Use this application.

thanks for this answer , but i'm still wondering why before installing cmw , my wifi was working flawlessly , and now i'll have to install this?!
and also what about this damn cmw that's here and still not working, is there a mean to remove it?!
This is common issue after CF root, and occurs due to binaries
Install busybox, open busybox and install binaries inside busybox application, once successfull installation it shud work
Otherwise
Flash stock kernel - wifi will strat working again
then root - install busybox - install binaries, then flash CF root kernel.
thanks doc for your answer ,after reading it, i'm willing to flash the stock kernel , at least it'll remove me this Cmw, but i must confess that this operation scare me , heard a lot about the brick issues with the xxlpy kernel , so i need some advices :
1 - i've downloaded the rom but it's a no wipe one , will it remove the cmw and the super SU?! otherwise how should i do to remove it?!
2 - what are the risks and what should i do to avoid them
3 - if u cand send me some links about how to flash this rom and how to remove all from my phone i would be greatly grateful to you
thanks a lot for your answer and have a nice day
Which ROM you are using?
yes non wipe ROM also remove it, but m thinking just flash kernel not full ROM
thank you doc you're my savior , i've downloaded the N7000XXLPY_N7000OXALPY_N7000XXLPT_HOME.tar.md5
so i was willing to install it , and where can i find the kernel ? it it better to use the kernel only or does this one ok also , btw i've deleted all on my phone so i don't mind
also other problem - as if the actual one isn't sufficient --, i'm trying to install the usb driver for my computer but can't install them , kies is on my computer but still not detecting my phone , any idea about it
thanks a lot for your help i'm attached to my keyboard waiting for your answer
Oh you hav already download then just flash downloaded rom with.pc odin(with pda tab)
Sent from my GT-N7000 using xda premium
the problem is that my computer won't recognise my galaxy note even after installing kies / drivers , is there a solution to this ? what should i do i order to use odin and flash this md5?!

thanks doc i'm waiting impatiently for your help!!!!
Wifi Probs after rooting Note
Hello
I am having the same issues after rooting my Note.
Basically I'm using the UK ICS 4.0.3 Rom from Sammobile - N7000XXLQ2_N7000XXLPT_N7000XEULP4
FRESH ROM INSTALL UNROOTED - NO APPS ADDED
Checked that wifi picked up signal and worked ok
Checked that data connection picked up signal and worked ok
Checked phone was registered on network and seemed to be ok
Pretty fast by all accounts !
*****************************************************************************************************************************************************************
However...
NOW ROOTED - using CF-Root - SGN_XX_XEU_LQ2 - v5.6
APPS ADDED FROM PREVIOUS CWM 4.0.3 BACKUP IMAGE
YellowTriangle Away V 1.70 used to clear counts etc
Checked that wifi picked up signal and doesn't work
Checked that data connection picked up signal and works ok occasionally
Checked phone was registered on network and seems hit and miss - registered one minute then not the next - unable to make calls - have to keep searching for networks manually - turning phone on / off / battery in / out !
Followed the advice from the from the post:
http://forum.xda-developers.com/showthread.php?p=29554858#post29554858 - regarding 'SPEEDMOD K3-11'
****************************************************************************************************************************************************************
Now when I open CWM manager app, I get the message "This version of CWM manager should be used with CF-Root v5.0 or newer. It appears you are running a different kernel.Various features have been disabled"
Also still - NO WIFI !
Just seems a bit odd ??
Don't know about you, but I'm wondering what else isn't working properly and is it actually worth rooting at all ??

Uninstall kies
Install only drivers
And change usb port
Sent from my GT-N7000 using xda premium
as i said before , wifi is working - hope so - since i can see the networks available around , the only problem is that it's continuously try to get ip and log in ,
now i'm worried about that damn usb that won't recognize my phone , and let me use odin to reinstall my system
if anyone has an idea i would gladly listen
thanks everybody
is there any mean to install the firmware i've downloaded without using odin?!
thanks for your answers
don't be panic and your issue is not serious.
you can use Mobile odin if you having root. if your root is working then try flashing kernel with mobile odin
Still NO Wifi - After UK ICS 4.0.4 Upgrade!
Downloaded ICS 4.0.4 from 'checkfus downloader' today
Product Code: GT-N7000ZBAXEU
Latest firmware: N7000XXLRK/N7000XEULP5/N7000XXLRK/N7000XXLRK
Modified: 24/07/2012 11:17:01
Filename: GT-N7000_XEU_1_20120724111617_83hlhgn7j9.zip.enc2
Installed using ODIN - rebooted, checked 'About Phone' - Version 4.0.4
However I have since rooted it using the CF-Root-SGN_XX_XEU_LQ2-v5.6-CWM5
Yellow Triangle 1.70 - worked and cleared the counts etc
Installed binaries via 'busybox'
(Haven't reinstalled - 'Speedmod K3-11')
and it still suffers the same 'NO WIFI CONNECTION' problem I had with ROOTED 4.0.3 ics with apps I'd installed via a CWM backup rom image
Any tips on how to get wifi to connect would be helpful - cheers
thaank you dr.ketan the word u've sent me relieved me because , indeed i'm panicked rofl - btw the fact of finding the right words to comfort people....mm are u a real doctor? -
i'm hoping truly that your words are the reality and not only to reassure me hhhhhh
right now i'm copying the md5 and the odin mobile pro 2.45 on the micro card , cross fingers and wish me good luck guys
right now i've installled mobile odin pro on my phone , but the problem is that it's sticked to the loading screen where it' says that it's checking super user support , and i have some msg from time to time at the bottom of the screen saying that mobile odin pro has been granted super user autorisation for interactive shell but still waiting so i'm begining to wonder if the root is alright , and so i'm asking
can i re - root my phone using the cmw zip and the busybox zip on an already rooted device?! if yes i'll do it right now
thanks for your help i'm waiting for your answer doc
It seems you have partially rooted device.
And that is the reason wifi is not working, i am saying this since long, i fear you won't brick device just for small issue.
Still i am saying once see there is enough space on system ROM? (check it with overview page of Titanium), i think in partial root titanium still works, as it uses own binary. if no 15MB spcace remove some non harmfull app e.g. arura live wall paper, youtube,Goggle+ this can be installed later.
After this again install busybox
open busybox and install from inside busybox
you should see msg 'succesfully installed'
then open superSU, if asked update binary too.
then try wifi shud work,
PS : yes I M ENT surgeon
glad to see that u're doctor too - i'm doctor in anesthesia reanimation , and we have good contact with surgeons since they're all the time funny - glad to see that u told me that my problem is a small issue and it won't brick my device , so i'm feeling a little more relieved , but still have to solve the problem
and there's some questions :
1 - when opening super SU i have this msg : the su binary needs to be updated , continue? how can i update them since wifi won't work? is there some specific files that i can update by the memory card?!
2 - i have a full unroot button in the super su settings , would it be a good idea to fully unroot the device to re root it after with the busybox?!
i'm on my way to download and install titanium i'll tell you about space on system rom once i'm done
thanks a lot again doc

S3 i9305 - problematic wifi.

Hello guys,
I just want to share this problem with my S3 LTE i9305, this unit came from singapore (singtel), and im now using it in Cebu, Philippines. However i am having too much trouble with its wifi always getting Authentication errors (when i was still in stock firmware).
I should say i can rule out that my wifi hardware is defective, because I was using the wifi yesterday whole night in our house. downloading stuffs from play store, browsing, facebook and etc.
This is what i already did:
1. downloaded a Hongkong firmware (official samsung stock firmware) flashed with odin with no problem. hoping that the wifi issue is just a corrupt base firmware.
- still wifi is problmatic
2. Im on Cyanogenmod 10.1 4.2.2 Jellybean
- all functions are okay except for the wifi
WIFI SETUP:
keep wi-fi on during sleep: always
wi-fi frequency band: auto
wi-fi region code: usa
wifi optimiation: unchecked
It can seem to detect new wifi with strong signals but whenever you connect to it the signal 'literally' drops to one bar, and stop doing the connection.
the problem is intermittent, meaning:
sometimes it works, sometimes its not - and there is no definite time when it works and when not.
here are the details of my current device:
Baseband version: I9305ZHBMI2
Kernel Version: 3.0.64-CM-g9c2e2b; [email protected] #1; mon sep 23 15:03:19 pdt
Cyanogenmod version: 10.1.3-i9305

hello! sorry about early bumping.
with wiping phone flash stock rom <<-- how do i do this? and not corrupting any vital stuff inside my phone. I heard that EFS is a very important.
update:
if you're talking about these:
1.wipe data/factory reset
2. wipe cache
3. wipe dalvic cache
i did those stuff 10x already...
PROBLEM is INTERMITTENT: sometime it will connect just fine, sometimes not. << how am I going to work around this problem?
is there any way to low level diagnose the wifi system?
could it just be the hardware? - if hardware then there shouldn't be times that it can connect fine
could it be the software? - where to start?
How i wish someone can help me fix all these intermittent problems I am encountering with the wifi.
EFS etc its all in the Faqs and Guides .

Hi, i have been reading those giudes, and i havent encountered any special method of wiping as what you say... I have used odin to flash like 5x already, got into cwm wipe data, wipe cache and wipe dalvik cache...
I already have a backup of my efs in .img format, using terminal.
Can you walk me through?
Wipe phone flash stock rom and test .
I believe flashing via odin using stock samsung rom will wipe the flash. Is that correct? Or do you mean to say format the flash chip first before flashing with odin?... Im not quite sure how to do that.
Right now im using my celfone posting this message. Its just that this fone doesnt connect to other access points where the rest of wifi devices connects fine.
if you are referring to this guide:

i have done this many times already.

I have tried alot of different ROMS already and the problem persists.
Could this be hardware related?
are there people whos got similar issue?
It can connect to wifi right away if you're 2 meters line of sight of the router/access point.

Yes it could be.My phone had intermittent wfi and data.Turns out it was an "RF loopback timeout" problem.Needed fixing at service centre.HTH.

[Q] How do I proceed

Hi,
I'm new to these things. Please help.
I have partial problems with my phone's speaker. I want to try can it be fixed via System Update.
Speaker problem is kinda mind-bending. Not sure when it occurs.
Speaker seems to work fine when calling someone near. When calling from over ~10 kilometers, speaker distorts the incoming sound. Works fine with loud speaker, which kind of takes the problem out of being problem of my service provider.
I'm quite possibly going to take my phone to the warranty service. That's why I want to have the "Device status: Official", not "Custom".
My friend rooted and installed a custom ROM, which I didn't like. I made him uninstall the ROM but the root stayed. (Late 2013)
Now comes the part I think I f***ed up.
Started watching videos about urooting, unbricking and such. Now what I have accomplished is that I've pressed "unroot" in SuperSU and uninstalled it.
Soon to notice that I should've used some program to clear the Device status.
Not sure what Flashing Android means and when its done, but there is counter which should be put to zero?
Those two things are done in programs which require rooting? So what do I do now?
Installing SuperSU gives me error binary not installed, and SuperSU cannot install it. Someone in fixed this with restarting device in Recovery mode with QuickBoot program which, again, needed the device to be rooted already.
I want to have my System Update done by the "right" way, from "About device" -> "Update". Now it gives me "Your device has been modified."
Please redirect and guide me!
I have S4 active GT-I9295, android version 4.2.2. Ask about baseband, kernel versions/other statuses if you need those informations!
Thank you SO much for your time and help beforehand! :good:
ps. 2 year warranty is till 28.9.15
