Recently i just flashed my i9070 to JB hongkong firmware (zsmg2),then i kind of feel that i prefer the old firmware rather than this version of JB,Before this i had use GB XME region..So you all know the issues of this hongkong firmware right,i had search entire site to find the solution on downgrading from this hongkong firmware,but still didnt find it..i tried to flash up with a custom rom but still the baseband and the imei appear to be 'UNKNOWN'..so i was hoping for the experts here to tell me the solution for this one.Please!! :crying::crying:

Try to root and debloat, then try CoCore Kernel 8.x.
Powered by CM10.2
oh..thanks..but how exactly to debloat and to find cocore kernel..sorry for being such a noob

CoCore: http://forum.xda-developers.com/showthread.php?t=2140597
For the first time, download kernel, unpack, transfer kernel.bin.md5 to phone. Install Universal Kernel flasher and some root explorer (like ES file explorer or Root Browser) from Play store. Open Universal kernel flasher and install kernel.
For debloat look on links in this post: http://forum.xda-developers.com/showpost.php?p=49866354&postcount=3

i have a unit with UBKK1 baseband version, which i learned was a brazilian rom. Now i currently live in the Philippines and i cant get an ICS update thru kies here because of the rom. i went to the samfirmware site and found a Philippine rom, my question is can i flash this rom over the old GB brazilian rom using odin without any problems? my phone is currently unrooted thru the one click method, it was previously rooted thru the same method.
Ive also read you can change the country code, if i change it to the Philippine code and update thru kies will it work??
if you change the csc then yes you should be able to upgrade with kies tho i always download the rom i want then use pc odin its just a personal preference
Why don't you download Stock ICS ROM directly.... And flash it using pc odin??
can i download any stock ICS rom and just flash it with odin without any problems?
Yes you can.
Ive just now rooted my note on brazilian rom (stock GB rom), if i upgrade to the taiwanese rom using pc odin will i still retain root? and do i need to uncheck the usb debugging before proceeding with pc odin?
No you wont keep root.
Yes uncheck usb debugging.

if you want to flash phone in odin then phone should be in download mode,usb debugging is not matter,and you can root your phone again after flash,vie cf root make search at xda you will found that.

I would buy Mobile Odin Pro from the market, and flash this rom from here http://www.hotfile.com/dl/156659405/b6c3080/N7000DXLP9_N7000OLBLP6_XTC.zip.html . This will flash the correct rom and keep root.
thanks for all the helpful replies, i was able to successfully flash taiwanese ics firmware update using pc odin. and you guys are right, i did lose root. now the only problem is how to go back on root as i've frozen a lot of apps on titanium backup before and those apps aren't showing after the update. it seems like flashing over to a newer firmware didnt reset the phone. all my previously installed apps are still there.
Guys, after updating to ics, i couldn't install apks using astro file manager or even the stock file manager.Pressing the install button won't work. Previously on gb stock rom everything works. Is this an ics bug?

hi.
i have an Australian N7000B Note, and it is currently rooted on the latest available android in the country for the phone (2.3.6)
i have superuser and CWM installed.
i can boot into CWM and navigate with no worries, but whenever i try to install any custom rom, regardless what rom it is, i get the same error.
i really want to get off this crappy rom that Telstra provides with the phone, so any help is greatly appreciated.
many thanks
pic attatched of error.
Use ODIN to flash a stock ICS or GB ROM and then re-root and add cwm and try again
the issue you face is because your version is the GT-N7000B and the build.prop is for the GT-N7000 so its failing because it believes the ROM is for a different device.
if the product codes do not match up in the build.prop it will fail - this applies to all devices and all ROMs.
you could also open the .zip and find the build.prop and change all of them, But its a pain in the ass !

Because these are for the N7000 if i flash a stock ICS rom on my N7000B what will happen?
http://www.sammobile.com/firmware/?page=8
Put your details in there and it will find you a stock ROM. Ive seen threads where N7000B users have flashed N7000 ROMs without any issues.
EDIT: You CAN use any GT-N7000 firmware !
Awesome! I am downloading the Gingerbread Australian Rom as we speak for the N7000. if i flash it with odin, root it, and then install CWM would it work with installing custom roms such as paranoid android etc?
Yes because the Stock firmware will remove the 'B' and you will have no more install errors
Be sure to follow the instructions to the letter !! and make a nandroid before commencing.

Well, i have a nandroid backup of the current firmware, i made it just after i rooted it.
so, i will flash it with Odin on PC correct? does it require i wipe everything off the phone?
sorry for the questions i am a noob lol
you can wipe before or after it makes no difference so long as your on GB.
Dont ever wipe on ICS unless your on a safe kernel.
But do do a wipe as it will start you off on a fresh clean install

Problem is you are still running Eclair?, Update your ROM to Gingerbread for it to function better with latest apps
but IF you must have only Eclair and want to root it, you can try various rooting tools found at Collections for Android link on my signature

Im on Eclair, but I dont want it anymore, I want to have the new Jelly bean, but cant have acess to root, neither rom manager neither CWM, so cant install nothing by that way... as I tried severals updated.zip and no one can work...
I was thinking, only if I flashed some ROM through ODIN3, like for example:
- http://forum.xda-developers.com/showthread.php?t=1326416 as that is possible to flash over odin, and then i can flash some ROM with Jelly Bean through Clockworkmod...
Is that the best way?
It would work if I flash that ROM using ODIN, on top of Eclair 2.1?
Need some help here ^^
EDIT: Just saw that on your sig and in your post: http://forum.xda-developers.com/showpost.php?p=11113557&postcount=1

Yes, you need to use ODIN3 to Flash the ROM, since your goal is Jelly Bean, you need to be on Original Gingerbread First, to do that go here and select the Firmware according to your location http://forum.xda-developers.com/showthread.php?t=1102881 ..Follow Flashing guide to the dot
Than go here and install a semaphore kernel, which will give you root and CWM http://forum.xda-developers.com/showthread.php?t=1112908
after that you need to visit the Jelly Bean Developers thread of your choosing and follow their guide to install Jelly Bean ( BUT be aware Jelly Bean is NOT fully Stable yet)
Darky's Resurrection ROM is for those who are having problems , yours is Just a Normal upgrade, so best use latest Original Firmware, First

Recently i have come across a puzzling bug when i flashed deodexed UK firmware S5830IXXLK3 (by Alucard1989PL) and was wondering if anyone else had come accross this,
I flash my phone via ODIN 3.07 to stock XXLK3 UK firmware as normal , this gives me stock kernel & ROM.
I fire up ODIN and flash either Rafael or Hells kernel (it doesnt matter which), reboot, check phone status and i have IMEI.
I root my phone via CWM next just to make sure and check that debug is ticked, reboot.
I then flash the S5830IXXLK3 deodexed ROM via CWM, no problem. When the phone boots i check the phone status and each time i have lost my IMEI number.
On all previous deodexed ROMS i have used i have never come accross this, could it be the latest firmware thats been deodexed or am i overlooking a simple detail here?
Any comments would be appreciated.

Hi Viprdxd, I have also just experienced this problem after flashing the same XXLK3 UK firmware and then flashing a custom deodexed ROM that I am currently building. My custom ROM is currently based on XXLI1 firmware and I thought there may be some incompatibility problem. However obviously you have flashed Alucard's XXLK3 deodexed ROM so it can't be that. You say its not a kernel issue either so at the moment I currently have very little idea what is causing this. I need to find out though to make my custom ROM compatible with all firmwares so I will be investigating this issue.
I'm just glad I got my IMEI back by reflashing the XXLK3 firmware with ODIN cause I've already permanently lost it once before when I was a bit of a noob and didn't have a backup or anything!

Yeah I know that feeling all to well when you see your IMEI number missing I'll keep playing around to see if I can find out why but my feeling is its an issue ROM side with XXLK3., Hey good luck with your ROM I'll defo check it out when its done.

Nice one thanks :good:
Edit: Sorry Actually I still can't figure this out, if I flash XXLK3 with ODIN, IMEI number is fine. If I install Rafael's kernel, nothing else, it disappears.
If I extract the XXLK3 ROM and flash it in recovery no problems, if I deodex it no problems, if I install custom kernels then IMEI dissappears.
Which leads me to the conclusion its a problem with custom kernels except for the fact that if I flash the ROM I'm building on stock kernel IMEI also dissappears!! So for now it remains a mystery!

I have concluded that its not a problem with XXLK3 or The custom Kernels as both work, let me explain, XXLK3 standard and deodexed on stock (came with package) kernel works as it should. Raf's or Hell's Kernel works fine on every other firmware.
It seems to be a problem of compatibility of the two maybe Samsung changed some small detail or a tweek is needed in the kernels or both? I don't know as I am not a dev.

Hi there.
1. It's necessary to note that samsul not do the update again on device S Advance through direct ota for those who still use the stock Gingerbread (GB). While still using the stock GB I once never get a firmware update but only minor updates. BUT you can to do firmware updates manually, by downloading firmaware directly from some of the sites that provide specific firmware for your country, such as: sammobile*com, samsung-updates*com.
Note: I assume if you expect an update to a firmaware. But if you run into problems updates an application from playstore, then I suggest you to do a wipe applications through: settings - application - select playstore and wipe data. Then try reboot. But if it still doesn't work then, try to wipe data / factory reset through default recovery.
2. If you still want to use the stock GB and want to root your device, then you can follow a guide on the thread here. You can try some of the menu that is available there may exist that are suitable for firmware are you using now. Honestly I never tried it.
3. For flashing method is the same on every device model samsung, using Odin application. For the method of rooting the device janice as far as I know have several methods, depending on which firmware you use now. If you are using firmware Stock GB then you can follow the above method. But if you use the stock firmware Jelly Bean (JB) then you can use the method on a thread here.
Hopefully it helps & Good luck.
So the matching firmware i download i can flash it using odin without needing root or anything?and if i dont update and root gingerbread,can install cm11 from gingerbread?
The end result im looking for is cm11 running on my device. Your help is much appreciated

No.. Just flash from stock GB to Stock JB via odin. And.. Done.
I cant find the exact firmware for my country. Will flashing other countries firmware brick my device?
