[Q] Wifi problem - LG Optimus 4X HD

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.

[ROM][CWM] Honeycomb 3.1 - Touchwiz UX - WIFI - DEODEXED (Updated 7/22/2011)

Pretty basic release. This is a deodexed version of the touchwiz wifi update.zip available in this thread: http://forum.xda-developers.com/showthread.php?t=1167250
I have not changed anything else in this ROM (though I am now working on a more streamlined touchwiz ROM using this deodexed version)
So no, this ROM is not meant to improve performance or fix any bugs from the stock touchwiz update. A deodexed ROM simply makes it possible/easier for devs to create patches that can address these issues, make themes, etc.
Warning: I am not responsibile for any damage you do to your device from flashing this update. Please be careful and follow the instructions below, and use at your own risk!

Uploaded 7/22/2011: http://www.multiupload.com/WTU98VP2D5
-Fixed WiFi issue (thanks to DocRambone for the fix)
-Fixed /system not being wiped properly during update
Installing:
Download and place somewhere on your /sdcard directory
Boot into CWM
Wipe Dalvik Cache
Wipe /data and /cache (you can skip this if you had flashed the r4-7/19/2011 previously)
Install this zip from sdcard

Before reporting any bugs please make sure you have followed these directions. If you are getting a boot loop you most likely missed one of the steps above.
If you are getting the "service temporarily unavailable message" you need to sign into your google account, it should go away after you do that
Have fun themeing and modding!

Thanks to:
pershoot - for the update.zip and the rooting zip

Does this mean i am the first...
To try this.....HMMMMM - let me sleep over it.
Oh - what the heck!
is this intended to be any less laggy or faster than other roms? Thanks for your hard worK!
Interesting....very interesting. Might have to give this a look-see...

No, this update will make it possible to create and use modified versions of the apps + framework resources contained within the touchwiz ROM (i.e create themes, etc)

Are you talking about the special tilt / pan control? Just tested that, still doesnt work, but it may be possible now to patch the problem if someone can find it (in the deodexed resources).
Yeah I like the zoom feature, that's why I went back to the stock 3g touchwiz rom
Yeah i still didnt go back to stock 3g im just hoping somebody can find it in this deoxed rom but lets see
Can you pleaseeeee hook me up with the 3g touchwiz .zip??? IV looked everywhere! My tab is sooo slow with the wifi version but the 3g version, even with errors, was smoking fast! Thanks!

Do I need to flash root, right after flashing the ROM? I tried to flash, without rooting right after and got caught in a boot loop. Restoring right now...but would like to flash touchwiz

I don't think it really matters when you flash root bro. Make sure you are using pershoots tools pack though.

The linked root zip is optional, you don't have to flash right after, you can flash it whenever (but dont use any of the other rooting zips available for this tab, the linked one is the only compatible version). Your bootloop is probably caused by not wiping /data+/cache or the davlik cache. Follow the instructions in first post.

Did you try without ROM Manager the first time? If not try that first to be sure. Also provide device info please (wifi/3g/io/retail/v). I have not had any other reports of bootloops from people that were wiping data+cache+dalvik properly. You can try formatting /system (under CWM mount / storage menu option) if you are still getting this after manually doing everything through CWM at boot.
are you sure thats the 3G version? I went to download it and my pc sees it as exactly the same as the new wifi version... thank you sooo much for it either way! good looking out!!!

Wifi Retail, Locked Bootloader
I am downloading it again to make sure its nothing weird with the zip. Every time I have flashed it was CWM not in the ROM Manager. Should I try that instead?

No if its not working in CWM it wont work if you do it through ROM manager. Redownload and verify the md5 hash from the original post. Boot into CWM recovery, wipe everything mentioned and retry.

Samsung S plus (i9001) Auto-restart problem, and other issues

Hello to all!
First of all thank u xda for beeing so usefull to all android users (like me).
I bought my s plus in April, one week later i´ve sucessfuly rooted (thanks to xda developers ).
Unfortenely this model by samsung isnt popular in my country (Portugal) and this time I could really need your help.
My s plus auto restarts. Sometimes 1x month, 1x week, today por example it restarts 3x in 1 minute. I know when he restarts because i hear the welcome song from samsung.
My question is, is there something I could do to solve this problem?
And the second questions is, what are the benefits of having a new rom. And if it solves problems like this one in particular.
The last question : there´s a app that does "fix permissions". Could this be the source to my smartphone restart??
THANK YOU
First, what ROM do you use? Is it brand one, (i.e you didn't change it since you bought the phone)?
Secod, which apps did you give a superuser permission? For example Invalid or infected app with root access could cause this. Generally rooting your phone means you can easily mess up something (you are administrator, so you can access ALL system files). Try to do a factory reset (for example hard reset with the code *2767*3855# - be advised in will delete EVERYTHING exept your external sdcard and get rid of ROOT) and then install only those apps you trust.
Yes, changing ROM could fix this problem in particular, the same way reinstalling operating system (e.g Windows) can fix a computer if it misbehaves. However this could also be a hardware problem, and in this case flashing ROM won't help and you should take your phone to manufacturer on warranty.
On the other hand it is good to flash custom ROM on i9001 because this phone has a good potential, and custom ROMs will give you a lot of advantages over brand ROM.
Fix permissions is a script which ensures that every App and App data are on their place - matching themselves. If used properly it rather fixes problems than causing them (I used this option a lot), but I am not specialist at this matter.
Hi there.
Thank you so much for the reply!!
The rom of my smartphone its the brand one.
Other specs : Firmware : 2.3.5
Gingerbread.bukp2
I have installed the app superuser + link2sd after I rooted. So i think all the programs have permission. Each time i install a app, it goes to sd card.
I was avoyding a factory reset. I will only do that if there is no other option. And when I do, i will get rid of root and go to the vodafone store with its warranty.
I allready see that there are a lot of roms for the i9001 . I agree with you, there are a lot of pottencial in this phone. What sould i choose? And to install other rom, will it erase all data??
I have the app ROM MANAGER. I never used because i´m afraid not using it right. There is a option that says : "fix permissions".
So..lol....can you give me some advice??
Thank you

Hi there.
So i´ve found several websites that explains how to update to 2.3.6
I have a question, I´m from Portugal and in here there are no oficial updates from samsung, the latest its 2.3.5 .
Can i install a version from other country in Europe? Portuguese language??
Thanks
Don't be afraid o losing data - that's what backups are for. Flashing new ROM means losing all data - system partitions, apps, settings, contacts, call history, sms, and your internal sdcard (/sdcard partition). External sdcard (/emmc partition) is not touched.
Find a "Flashing a ROM" guide on this forum, read read and read it again. Then you will know pretty much everything needed to flash a new ROM.
There is a good site to begin with: http://forum.xda-developers.com/wiki/Samsung_Galaxy_S_Plus/GT-I9001

Hehe, that's how fixing thing work. Maybe it'll work, maybe not
Some other guy claims that its the problem of brand 2.3.3 ROM, so factory reset WON'T solve this problem in my opinion. You have to flash new ROM. What can I suggest?
If you are not afraid o losing warranty (I wasn't) I'd install MoonROM or BroodROM. These are heavily modified custom ROMs, that are very stable, battery friendly, very popular, very customizable, tested many times and considered best. Note that replacing brand ROM voids your warranty, but you can backup your brand ROM with recovery (e.g TWRP - Team Win Recovery Project) and restore it anytime you want (restoring your warranty as well).
If you don't want to lose warranty, it's good to install Stock ROM. It is official ROM released by Samsung, but not ported by your service provider. On this site, there is also list of Stock ROMs. Almost all of them have european languages.
http://forum.xda-developers.com/wiki/Samsung_Galaxy_S_Plus/GT-I9001#Gingerbread_2.3.6
XXKQ1 is most stable and best Stock ROM so far.
XXKQB or XXKQE are prettier (value pack) but more buggy and less stable
Cheers
Edit: Don't use Kies to flash a new ROM. I soft-bricked my phone with it. Flash via Odin or via Recovery
I haven't backup of my stock rom. Now my USB it is broken. Is it possible to flash a backup stock rom to send my phone in warranty?
Thank u so much for beeing so usefull!
I will try a flashing rom!
I have one last question : do i need to unroot my phone before flashing a new rom ? The costumized roms gives us superuser permissions ? I rooted my phone so i can pass the apps to the sd card and to unistall apps like "sims trial...".
Maybe tomorrow i will try to flash a rom, but first i need to know this
Thanks a lot

BigBearEvo's Stock with root

Got my Salsa yesterday, and used the great guides here HTC DEV- CWM route..all working great, custom roms are a little full for me awaiting new & faster SD card to try those again.
So reverted back to BigBearEvo nice post of Stock with root, weirdly SU doesn't seem to be allowing root access to anything, and often FC. Hrmmm am I missing something here??
any help, v.much appreciated
Try flashing root.zip via CWM, and see if that helps.
Option 1- Did you root the phone before installing the ROM ?
Option 2- Did you wipe and flash the ROM hoping for root access ?

hrmm, strange, I already tried flash root.zip late last night
and ...err yes to option one
and well option 2!
no matter the FC are more of an issue tbh, I'll just rip apart a custom one and make it a little lighter
thanks for your help
When you say well to question 2 i would assume no. Then that's the reason why its not working. It's conflicting with the previous rom. All my stock with root is .......stock with root.zip applied. That's all.
Sent from my HTC Salsa using Xparent ICS Blue Tapatalk 2
In continuation to what BB has said, if its conflicting. Try 3 wipes mandatory and then install ROM, set-up and then examine if any FC issues still persist and then report.
When I tried I was rooted before and then I did the wipes and it was up and running. As BB has said root.zip has been included with that ROM.

[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.

Going back to stock

Hey, i want to return my phone to the stock xiaomi android.
anyone knows how to do that?
currently im on latest evolutionX.
thanks
Was about to ask the same... I think you just need to flash the stock rom, if you are on f2fs you will have to format and change partition type, as stock kernel doesn't have the drivers for it
