No, I just notice 2 red lines on the boot but still don't have WI-fi or Bluetooth.
[Samsung Galaxy Mega] Kangburra:
Do a nandroid backup, flash a whole stock Rom and see if the wifi works.
[Samsung Galaxy Mega] sholsten:
I went through the unroot on the Superuser. After I rebooted it a couple of times; everything went to working again. Funny thing was it was still rooted for some odd reason, but all is well now.
[Samsung Galaxy Mega] trurl3:
There is list with stock rom's on http://xdaforums.com/showthread.php?t=2330052. Is it important to choose one from my region? What are the differences? And what about kernels?

I have rooted my Mega using rooted kernel (vcore_v2) and to avoid 2 red lines I should (as somebody advised) stock kernel, so I done this. I see so roms and kernels are paired on list. My rom is from France. What I can do? To chose kernel from my region independently of ROM ? I found one kernel designed for my region and flashed kernel from it. But now I have random softreboots which were not earlier with rooting kernel . Can it be, so wrong kernel can cause these softreboots? Have I flash now complete ROM? If so, maybe i can flash rom designed for my country but not for my provider? Please advise.

//EDIT Flashed stock kernel once more and now all is o.k.

When I was flashing TWRP recovery there was one issue-if rebooted after flashing then recovery was all stock. The trick was to not reboot after flashing recovery but instead go immediately to recovery itself. That made custom recovery 'solid'. Let's try this.
[Samsung Galaxy Mega] sholsten:
I tried to load the one ROM on TWRP & it crashes. I had to go back stock with Odin,
[Samsung Galaxy Mega] shayneflashindaily:
Load what one rom? Are you talking about flashing a rom? Restoring? It helps to be more descriptive

[Samsung Galaxy Mega] Keror0:
How to go immediately to recovery mode while in downloading mode without rebooting?!

I encountered the same problem of cannot flash custom recovery, I expect if the phone get rebooted after flashing the custom recovery, the stock kernel will re-install the stock recovery and over-write the custom recovery.

I can only install the custom recovery by flashing the boot.img first.
[Samsung Galaxy Mega] trurl3:
Yes you are right, if you reboot to Android ater flashing custom recovery the stock recovery will be reinstalled. The trick is to not reboot to Android but during first rebooting afer installing custom recovery go to recovery itself. Then you can reboot to system as custom recovery will stay firm.
[Samsung Galaxy Mega] Keror0:
I flashed the stock kernel again but still cannot get rid of the 2 red lines upon booting into recovery mode, I suspect it is something related with the change of stock recovery to custom recovery because when I first saw the 2 red lines it was as soon as I flashed the custom recovery. I don't even rooted or flash any custom kernel at that time.
[Samsung Galaxy Mega] Tilagoon:
Yes, the 2 red lines will always be there when you boot in Recovery mode !!

[Samsung Galaxy Mega] trurl3:
Do wipe only cache and dalvic cache. It should work.
[Samsung Galaxy Mega] myabc:

Halo Expert,

I've just OTA my I9200 into I9200XXUBMJ4 XSE, now facing the problem, after I flash 6.0.3.2 June then boot into CWM and at the centre said that No Command. Is there a new update for I9200 CWM ??

Thanks
[Samsung Galaxy Mega] Thatgrass:
Hi,

I've rooted a my phones in the past and I want to root my mega too. I have a i9205. Is this all confirmed working and is it easy to get rid of those red lines at boot? Where can I download a stock kernel/Rom if I want to get rid of the lines/want to get back to stock?

And about Cwm, is it safe to flash? And fully functional?

Sorry for the questions, but I don't want to brick my phone without having a backup ;)

Thatgrass.
[Samsung Galaxy Mega] Silesh.Nair:
Just flash the twrp recovery and you'll get root. The red lines will disappear when you flash a stock recovery.

linux busybox commands

It's probably been mentionned but I thought I'd share with you anyway :

If you want the linux commands usually provided by busybox under your terminal (command line) just install the busybox app by Stericson : https://play.google.com/store/apps/details?id=stericson.busybox

and run "install" ... (I chose the "smart" option), it will then create the missing links to the commands ...

PS : here are the commands/functions provided by busybox :

need help... error flashing

help me someone out there.

i have a mega with pictures, loads of them... what i did was follow this guide to root my mega i9200. after flashing the vcoreroot in odin, wifi didnt work, gallery didnt work, loads of stuff didnt work, and my internal memory was 8gb.. what do i do now? do i flash in a new stock rom or how do i get a new stock kernel?? or do i flash the boot.img.tar as pda? will i lose all my data? help me please
[Samsung Galaxy Mega] andrewsena:
Doesnt Work

Dear forum moderators,

the root via vcore doesnt work anymore. please get it looked up. lots of people online are getting this problem as they flash the root. problems are all of the internal storage are gone, left with 8gb and all apps in storage wont work.
[Samsung Galaxy Mega] crazeeangel:
Hi Andrewsena

Can't help with rooting your phone but I had exactly same issue trying to root using the vcore file. I found link here to official firmware and restored this again using odin 3.07 and everything went back to as before. I still have no root access but I do at least heave a fully functioning phone. Hope this is of help to you.

It is a big download and takes a while to install as this is complete firmware but it does the job and best of all no loss of apps or data. Big sigh of relief :o I suspect though I am no expert in these matters that the rooted ROM is incompatible with latest firmware.

I cannot post links as I do not have enough posts but do a google search on this text and you will find link to the download. Hope this is of use to you and perhaps others in same situation.

I have got my mega fixed.... flashed stock rom using Odin and i got all my pictures and everything working again. I almost succeed in rooting the Mega, thanks to starmaster10, but i failed due to KNOX preventing the Super SU. Still trying .

To know how to actually root the Mega safe way, use starmaster10's method here.

Then put UPDATE-SuperSU-v1.93.zip onto your sdcard or external sdcard if you have one installed and flash it with the recovery and that will give you SuperUser status then and your phone will then be rooted as it works good doing it this way, by flashing the original rom or even a custom rom you should not lose your pics as that is usually left alone when doing this or can be synced with your google account if you did it this way.

This is what i would try first and see how it turns out especially when you flash the original rom..boot it up and see if you got your stuff back..unless the pics got deleted some how, use odin also to flash the original rom..just unpack it from it's zip file first and use the tar file inside.

Also do not wipe your internal sdcard as if your pics are on there it will delete then, you can do factory reset and the other stuff...let me know how you make out.
[Samsung Galaxy Mega] mwarrington1992:
Not sure what you guys are going wrong but this has been the easiest root ever for me...

Downloaded odin

Downloaded the root file here

Opened odin clicked PDA attached the TAR file (DO NOT EXTRACT)

Press start

Then its done.

Literally took me two mins, this file should not be taken down just because it doesn't work for you. Maybe you should share build and baseband numbers to see what devices it does and doesn't work with. Do you have newer phone, did you buy it when it only just came out? Maybe Samsung has changed something in their newer devices...

Successfully rooted on 9205. But NO WIFI. CANT TURN ON AT ALL. HOW TO FIX THIS?
[Samsung Galaxy Mega] Tilagoon:
What is the version of your ROM ???? :confused:
[Samsung Galaxy Mega] ayenzel:
4.2.2 , xxucna3
[Samsung Galaxy Mega] Tilagoon:
Your ROM is now having Knox and you have root it with the wrong procédure !

Have a look Here for the method to root this kind of ROM :)
[Samsung Galaxy Mega] ayenzel:
The problem is WiFi not working. WIll it work again with the method you tell me? Im noob and freak out cause this is my mom's phone
[Samsung Galaxy Mega] Tilagoon:
Yes Wifi not working is one of the consequence.

If you want to root it you must use the procedure given.

If you don't need root just flash the stock ROM with Odin.
[Samsung Galaxy Mega] ayenzel:
so forever no WiFi? Also, Gallery FC..
[Samsung Galaxy Mega] Tilagoon:
Well you have to flash again the stock ROM and every thing will work again.

If then you want to root the rom you have to apply the procedure given.;)
[Samsung Galaxy Mega] ayenzel:
I just finished flash the stock rom. and everything works again. THANKS VERY MUCH.. :D
[Samsung Galaxy Mega] Tilagoon:
Good news :good:
[Samsung Galaxy Mega] Simone:
Hi, I have baseband version I9205XXEAMC3, can I use this version of rooting?

Android version 4.2.2 without Knox.
[Samsung Galaxy Mega] sytauro:
Broken Wi-fi

Your other rooting method fails on my i9205.

Is there a fix for the broken wi-fi after vcoreroot2 method?

Not having root is driving me mad. Any help would be greatly appreciated.

Steven Young
[Samsung Galaxy Mega] Tilagoon:
Well, if you have a ROM with Knox the is (AFAIK) no other way of rooting the Mega than the one given which should work w/o problem.

To recover from the wifi problem you have to flash the stock ROM with Odin.
[Samsung Galaxy Mega] sytauro:
Wifi not working

Tried several times, but Supersu always shows this error.
[Samsung Galaxy Mega] Tilagoon:
Have a look at the OP for this root method HERE

In EDIT3 you will be send to post #153 were hopefully you will find the solution.:fingers-crossed:
[Samsung Galaxy Mega] sytauro:
SuperSU 1.8

Where can I get version 1.80 of supersu.apk to put on the sdcard?

I use UPDATE-SuperSU-v1.80.zip but the apk I have is v.1.9~ Perhaps the newer supersu.apk will not allow the update to work?
[Samsung Galaxy Mega] Tilagoon:
To get the supersu APK you just have to de-zip SuperSU-V1.80.zip

The APK is in directory /common ;)
[Samsung Galaxy Mega] sytauro:
Didn't work.

Do I really have to do a full wipe?

I don't want to wipe my phone and still not get root.
[Samsung Galaxy Mega] Tilagoon:
Well the procedure says full wipe !! I Can't be sure it will make it work but you can do make a Nandroid backup and try full wipe.

If still the same just restore the backup.

May be another solution: You should be able to downgrade to a stock rooted BMJ2 (Without Knox :good:).

There is a procedure to do that HERE :fingers-crossed:
[Samsung Galaxy Mega] joeldemaj:
same problem here. more bad news when cannot open play store ,gallery .cannot launching WIFI also..luckily i successful to restore the kernel using Samsung Kies and i got back my phone to original state..
[Samsung Galaxy Mega] vilks:
can anyone write me how to root my galaxy mega 6.3 ? becouse its not enough info in here.
[Samsung Galaxy Mega] Tilagoon:
Hi,

Depend on the the Android version of your ROM the procedure is different.

If you have a ROM with Knox you have to use this tutorial

What is your ROM version ??
[Samsung Galaxy Mega] vilks:
my version is 4.2.2
[Samsung Galaxy Mega] Tilagoon:
Yes but we need the version of the ROM to know if Knox is installed or not, as some version of 4.2.2 have already Knox.

Go to Parameters / About the phone and give us the last line at the bottom.
[Samsung Galaxy Mega] vilks:
sepf_gt-19205_4.2.2_0019
[Samsung Galaxy Mega] Tilagoon:
I am looking for something ending with CNA2 or DNA2 or AMH1 or AMG7 or something similar.

I thought it was on the last line !!
[Samsung Galaxy Mega] Tilagoon:
Ok , so your ROM is a CNA2, if you want to root it you have to follow this tutorial
[Samsung Galaxy Mega] vilks:
thanks a lot. i will try to read and understand this :)
[Samsung Galaxy Mega] vince2709:
hi, i just got my mega i9205 updated to latest firmware for my country, singapore...may i just ask someone to kindly dictate the steps to root and with custom recovery, sorry i'm unsure of which procedure to follow in this thread... thx in advance :D
[Samsung Galaxy Mega] vince2709:
Okay i tried, i started with stock 4.2.2... i successfully flashed vcoreroot-v2 with superSU working BUT my wifi is turned off and i can't turn it on at all... managed to install cwm and now just stuck with the wifi not being able to turn on :( Pls tell me what i'm doing wrong
[Samsung Galaxy Mega] alexischino:
Flash your stock rom with odin to fix your wifi if your wifi is not working when your phone boot up enable usb debugging under the settings reboot in to download mode and dirtyflash your stock rom again.
[Samsung Galaxy Mega] vince2709:
Hi thank you for the reply and sorry for late reply.... basically i flashed vcoreroot and then my wifi is disabled... are you telling me to reflash my stock firmware which is the .tar.md5 again? All that did was yes fix my wifi problem but then i get unrooted :( fyi i didn't clear any cache or wipe data after the wifi prob.... please further help me on this... thx
[Samsung Galaxy Mega] vince2709:
Oh by the way, the stock firmware i'm on now has knox :/ if that matters... i need help on procedure to root and obtain custom recovery... i'm fine with either cwm or twrp... oh and will kingo root help by any chance?... i'm very lost...sorry!
[Samsung Galaxy Mega] alexischino:
Knox is not a problem, first you need to flash a custom recover with odin here http://xdaforums.com/showthread.php?t=2588661 when your phone reboot download the supersu flashable zip from the link below and turn off the phone and reboot in to recovery and flash the superSu flashable zip from here http://xdaforums.com/showthread.php?t=1538053 once you are done turn on your phone and go to the supersu app and open the app now it will ask you if you want to disable knox hit yes and you are done.... now you will have root access and a custom recovery.
[Samsung Galaxy Mega] vince2709:
Hi thanks for the reply but question: I have to root first before i can flash the custom recovery right? If that is so, what do i do with my wifi problem as it gets disabled after flashing vcore root. Oh and i'm already lost at your instructions to flash supersu zip. Sorry!
[Samsung Galaxy Mega] alexischino:
flash the recovery first after that use the recovery to flash the supersu flashable zip.
[Samsung Galaxy Mega] vince2709:
Alright i get you thanks, i managed to install that cwm and booted into that recovery once... but the next time i try, it will show the blue recover booting and the red lines but it wont boot into any recovery :( i hold volume up + home + power right? i managed to do it once because i unticked autoreboot...but now it won't boot into recovery at all.

Hi,

Have a look at this thread

For Knox: all ROM's for the 9205 starting with CNAx are having Knox !! So you have it !!
[Samsung Galaxy Mega] kraken77:
i need stock kernl cna2 please upload.
[Samsung Galaxy Mega] Tilagoon:
You can download the stock ROM from Samsung updates or SamMobile and extract the kernel !!
[Samsung Galaxy Mega] kraken77:
Why dont you understand my question? I need only the kernel! I dont have wifi here to download the stock rom. Before replying please read the question carefully. I know I can extract it but I cannot download the full rom thats why I asked for the kernel only.
[Samsung Galaxy Mega] Tilagoon:
Hi,

If you would have mentioned the fact that you could not download the complete ROM I would not have answered the same thing !!

Hi Guys... I know this is old... but very much related to my problem.

Galaxy Mega 6.3 i9205

Wanted to install android 5 or 6. But phone was OEM locked and no option to unlock in menu, so was not able to install TWRP or CWM...

Found this topic, and flashed vcoreroot-v2.tar with Odin 3.1 - went ok...

But it is dead now...

It starts, gives a startup sound, blue diode is flashing slowly, screen is blank - only bacground light is on...

Can go to Odin and to recovery mode, but no idea what to do ?

Odin mode says now, binary custom and knox went to 1...

Any help please?

Thank you in advance
[General Questions and Answers] Uristocles:
[This doesn't seem to be a phone specific issue so I thought I'd post it here in General, hope that's ok.]

The behavior of typing something in the Google Now bar and having it return installed Apps stopped working for me a couple days ago. Anyone else?

For anyone who's not familiar with this behavior, it's a really nice feature of the main Google Now widget:

Punching in part of an app name in the Google Now bar pulls up hits including installed apps.

It's very convenient to for example turn on your phone, type in "Scan", and get as the top hit the Genius Scan app for example (you might only remember the "Scan" part of the name of the app).

Or type in "Face" and the Facebook app shows up. (Partials work.)

It's very similar to the iOS left-swipe search, the Windows 7 Start button, and OSX Spotlight.

Hunting and pecking through the app list is for chumps. ;)
[General Questions and Answers] Uristocles:
A friend noticed that if you type in "Facebook app" or "Fac app" and then press enter you DO get an app result in Google Now card style with "Open app" as a button. If this is an intended change I believe it's for the worse and is less useful than the iOS left-swipe search, the Windows 7 Start Button, and OSX spotlight (because with any of these you can just start typing and once you've gotten far enough into the word, results will start popping up -- this was how the Google Search widget used to work a couple days ago.)
[General Questions and Answers] Uristocles:
After a Google+ update push this morning, no-chump app launching is now fixed.
