[Q] rooting. stock rom different from country of origin

so i just want to ask a question before i start rooting my note 2.
mine is the international version. when i upgraded to 4.1.2 i used the default system updater from the settings menu.
here is the screen shot of the "about" on my phone

and here is the image of my *#1234#
img713.imageshack.us/img713/8866/screenshot2013051322144.png
so upon research i discovered that my stock rom is from somewhere in the middle east and that the baseband version of my phone is from poland.
do i have that right?
now the problem is, is that i am from the philippines. and i dont know if my stock rom will give me any bugs since my OS came from another country?so will it affect my rooting? or is it safer to reflash my countries stock rom then root it? and is it advisable to download the latest stock rom for the philippines 4.1.2 april?
i cant post pics cuz im new. sorry guys and add the http in front. thanks!

Hey buddy it doesn't matter which rom you flash it's safe to flash any country stock rom no issues you can go ahead and root it.

first: my phone is i8160L, ive updated to jelly beans but the phone performs really slow. ram is always full and its verys frustrating.
second: ive tried to go back to ginger bread but the phone gets stuck in a bootloop. ive tried with an official firmware and also with the custom which have three parts. none of them works. odin shows me the fail message when i mark re-partition option.
so the thing is: how to really go back to gingerbread?
which files? which firmware? which odin?

is not allowing me not install other firm , only allowed GT-I8160L VERSION ONLY. WHICH ARE NOT WORKING , ANYONE can help me with GT-I8160L WITH 3 FILE or 5 parts please provide link please , thanks

I agree, JB do not perform well at all on th GT-I8160L I got, it can be used if turn of all animation and stuff like that but my biggest loss is that I can not run the 3 apps simultanously I need to use (Skype, Viber, CSip), the phone then is so slow I hardly can use it as a phone, I can never answer because the phone app starts so slow that the other part already hung up when I finally slide for answer :-/
I have EXACTLY the same problem downgrading to GB (I8160DXLF2_I8160OLBLF2_THL.zip), I have the official GB firmware and it installs nicely using Odin 3.07 but it get stuck in the bootscreen. If I then put JB (THL-I8160LDCME1, official thai) on it, no problem and it starts.
What todo? Please advice, anyone?

i m also
im about to upgrade my I860L. to that I860DOME1 .is it so slow that the phone is unusable. ithink flashing cm 10.1 or 10.2 will be faster

[Q] How to update from 4.1.2 custom rom to 4.2.2 or higher

Hi Everyone,
I do know how to flash a new rom however I had issues flashing from stock 4.1.2 to custom 4.2.2 before (device wouldn't pass the boot screen). So do I have to be on a specific 4.1.2 rom to upgrade or I need to upgrade to a stock 4.2.2 first and then upgrade to a custom one?
Please recommend a fast 4.2.2 custom rom. I would like to keep dual sim feature if possible although I know most roms only support single sim.
My current rom info:
4.1.2
Baseband: I9082XXAMC4
Thanks in advance.

simple one line if want dual sim,(stock based roms only)..u can install stock rom 4.2.2....or balliboxers GENNXT rom based on latest firmware...
NOTE: RAM USAGE OF STOCK AND STOCK BASED ROMS IS HIGH....SO LESSER MULTITASKS HANDLES!
if u can compromise with dual sim ..then u can install slimbean roms...(as u mentioned u want lightest and fastest)... but as they are small and fast, they dont have many extra feature lik halo..bt are lightweight..less ram usage...
bt i wonder why u want 4.2.2 rom when u can installl latest kitkat 4.4.2 (cm11,slimkat rom, carbon rom)..
they all are kitkat roms..........
with cm being a base rom for every rom and a light good rom...so is slimkat...and carbon with good future updates including halo features....
if u still wanna stick to 4.2.2 ....then u got slimbean rom...cm rom....(both dont have halo feature),.bt light...or u cn have PAC,resurrection remix rom(for halo multitasking)...
(gaming is better on kitkat roms)
its all ur choice....
if u want any qsns u can ..
hope i helped ..

First of all, thanks for your awesome reply
Basically I'm on stock rom without useless Samsung apps. Instructions for Pac/resurrection says I need to be on stock rom in order to upgrade to 4.2.2. So am I ok to flash their rom or first install a stock rom?
You mentioned kitkat roms are better and I agree, however based on instructions I need to be on 4.2.2 first before upgrading
Which recovery is the best for making nandroid backups? clockworkmod seems to have issues occasionally creating bad backups.
Kitkat roms seems to have app2sd enabled by default, right? and no issues with Xposed framework modules?

xposed is working fine on dalvik runtime(as google introduced new runtime with 4.4 named ART ,WHICH CONSUMES LESS RAM, BUT IS UNSTABLE)...
when they say that u need to be on stock ROM 4.1.2 , they actually mean the 4.1.2 bootloader..so its okat if u are on GENNXT ROM...stock..abit modified stock 4.1.2...(they specifically mean that if u want 4.2.2 rom, be on 4.1.2 bootloader...and if u want kitkat rom..then be on 4.2.2 rom(any stock based 4.2.2 rom like gennxt or slight modifyd 4.2.2 will do , as all they need is 4.2.2 bootloader for kk roms to work)...if u want kitkat rom.....be on stock based rom..which are touchwiz based roms of 4.2.2)....
so flash 4.2.2 rom by odin..and den install kitkat...if u face any problem ....just pm me ...and ya..
always do wipe cache,dalvikcache and data(if told) , whenever u flash anything(before and after flashing)... u can ask any qsna u wanna ask..hope i helped.

one question from my side as well.
I am on stock rooted 4.1.2 rom and I want to upgrade to stock 4.2.2 rom. what would be the best method?
can I install 4.2.2 latest version by flashing via odin directly or do I need to unroot first?
or it will be automatically unrooted when I install 4.2.2(stock) latest over my 4.1.2(stock) by odin?
I hope you got my question.

I finally got the chance to upgrade to stock 4.2.2 via odin and gaining root again. However I was unable to install kitkat. Even though I wiped cache and did factory reset, boot didn't pass the samsung logo. I still have 2 sim support, is it worthed to install kitkat? According to your previous instructions, I needed to be on 4.2.2 base in order to upgrade to kitkat. What would you suggest in my case
Thanks

I am a heavy gamer and performancive device addict..
Kitkat dont have any fancy samsung stuffs bro..bt its all system files are of kitkat so the gaming performance is alot increased.. All game bugs are almost fix which were in 4.2.2......there is work around for every thing..
I mean..think about it..
I never use smart stay...
I nor did use much of live wallpapers as they were battery consuming..the lock screen was fancy but still lets face truth that its just meant for security/unlocking screen ...u will have to compromise with single sim and non fancy apps ..
But it does worth a try..i mean why not ... Give it a shot and i am sure u will find something unique about it...
It got its own features..so ya...its ur wish..there are also downsides of it .....u can check respective threads and know more..
Hope i helped

Ok bro, I installed selinux cmw recovery... downloaded CM11... I noticed CM is about 200mb comparing to 1 GB stock 4.2.2. Does that mean I will get more free space on internal sdcard? (out of 4GB I mean)...as others suggested, I need to do full wipe/reset factory and manually format system? and if update wasnt successful I can go back to stock via Odin right?

[Q] Any other solution other than reverting back to 4.1.2 for lag issue ?

I am fed up with the lag issue in this GRAND duos. tried all these methods
(1) reverting back to amf7
(2) flashing bna4
(3) flashing ubmk3
(4) disbaled stock gallery app
(5) disabled as many as possible official apps....
All the solutions proved to be just temporary. After 24 hours to 4 days it starts lagging again. Now I am sick of flashing firmwares.
My phone is under warranty up to 19 April. If I go to service center and ask for replacement of motherboard/phone, will they replace just on the complain "my this phone hangs a lot. I have googled and found that many users have flashed other firmwares yet phones lag. These users say that this problem has no solution but replacement of motherboard?" (I cannot tell them that I have flashed other firmwares myself).
If any user with same problem has flashed custom ROM, please share your experience.

Bro, though I've never flashed a custom rom on my grand , but my Grand is rooted and I've flashed a lot of mods on it , but my Grand never lags . It is very fast and buttery smooth . I want to ask you that wether you directly started flashing custom roms on your galaxy grand or in the beginning you just rooted and flashed some mods like me ?

@MohdGhufran
From what date is your last stock ROM?
I'm having the same problem. But I've used the CM11 on another occasion and did not face any problem. Then I went back to Stock and updated the same last week.
The phone was very bad (lag). So I returned to the CM11, but the lag continues.
I'll try an earlier stock and after the CM11.
I'll post the result here.
(Sorry for my English by Google)

@Mohdgufran - I agree... I m running umbmk1 ... after 3 to 4 days with out restart the phone starts to lag...
The only solution temporarily is to clear the ram in task manager...
Stay wid 4.2.2 and use a ram cleaner (it sucks a bit battery but its the only possible non technical solution)

Have you tried a factory reset, followed by clean flashing a smooth ROM?? In my experience, THAT always solves any problem...

Its the stock rom that is cursed..:/

I think u need a reverse gear.. First back to 4.1 version then flash with 4.2 November month version then use cm 11 custom rom.. Its fast.. Gud battery back up.. No lag.. And all with dual sim.. I hope this will work for u..

Try greenify and the cleaner both are small apps (around 1 mb) and it will speed up your phone .....
Hit thanks if you find this usefull

Didn't root.

I have not flashed any custom ROM on this phone. Neither have I rooted it. This lag issue started since my bro got an OTA update. So, as per solutions/guidance available on xda, I just flashed official firmwares (which proved to be just temporary solutions)

it is not like that stock ROMs are not good. It is just a problem with Galaxy Grand Duos. I had rooted my Galaxy R and Galaxy S Advance and had flashed Custom ROMs. All the custom ROMs had some limitations / missing features (like USB PC connection, wifi tethering, USB tethering, etc). This is why I do not want to flash any custom ROM on Galaxy Grand.

Yes I had tried this. Went back to 4.1 and the upgraded to 4.2. This too proved to be a temporary solution.
I don't want to flash custom ROM but now it seems like I will have to flash the same.

I solved my problem by not installing facebook and twitter as well as also installed battery saver pro which kills apps running in background for every five minutes..

The procedure that I suggested (and I did after my post) did not work.
Finally I found the solution!!
I uninstalled Facebook and now everything runs normally!!!!

[Q] Up/downgrading with Knox

Hey guys,
I'm planning on installing CM10.2 stable on my galaxy s4 mini ( to check if the network-dropout problem i encounter sometimes still occurs)..and because i'd like CM better anyway. But before doing this i got a question about the KNOX- bootloader on my phone..
I already rooted my phone and installed CWM... the KNOX flag is triggerd 0x1.
Can i just install CM from the menu in CWM like in most descriptions ? Or is the KNOX bootloader going to give me troubles?
On another website I read this, and now i'm a little bit confused :
By downgrading from KNOX-enabled to KNOX-disabled firmware, your device will be locked to installation of newer firmwares.
Keep the above statement in mind all the time whenever you decide to flash a stock rom. Be careful not to flash a firmware that doesn't have KNOX.
CM10 probably got no KNOX right ? Am i still able to install this ROM ? And is it possible to go back to stock rom just in case i need to get it back to the shop for maintenance?
Thanks in advance.

Short answer : Yes u can install CM 11 / 10.2 . U will have trouble to install OLDER STOCK firmware ( before Dec 2013 ones ) ( MH2, MJ7, etc will give u problems ) New ones, like ML4 , C1, D2 , etc will be ok.

Ok thanks for your answer.
Is it true that this KNOX problem only happens when installing STOCK firmware ? Or also older custom-roms ?

Its a problem downgrading stock roms
With cwm you can install any version of CyanogenMod at any time always keep in mind you have to full wipe when upgrade or downgrade
