Fixed by @hainguyenthao
For a coffee. I did not know how.
Ha said it need server to fix kernel so i can not update, or something.
But he fix the kernel from remote, with USB redirector, then upload FW with ODin.
He suggested this: SM-G970F_DBT_G970FXXU9ETLJ.zip

Not rooted but can i update to ics 4.0.3?? So confused.

I just a saw a post in drip saying anybody with a note can update? It gives all the instructions etc so cab i or cant i? It mentions something about doing it through kies or ota and you dont need to be rooted.
Can someone break this down for me.
Cheers

If the ICS update is released for your country (or specifically the origin of your Note) you can update through kies or OTA officially
If it's not you can also use PC Odin to flash the update and you don't need root for that
However, I advice you wait a little bit longer until the issue with the kernel bug in ICS update gets resolved so you don't end up with a fried Note by accident
hey
so are you saying if the update is available for my country its fine to update, or just wait until the bug is fixed. cause the ota one or through kies is meant to be official. i dont fancy flashing any roms through odin or whatever
cheers

Yes, you don't need to root to be upgrade to ICS. And Yes, you can wait until your country OTA or KIES available - Yes, it is official in this way.
But... "official" kernel still having a serious bug which will damage your phone. So, the best is wait until the bug fixed.
U dont need root to install the official german ics. But its nice 2 have root and cwm for backups etc. However, after installing ics german i didnt feel it was worth the hype. Touchwizz makes it feel exactly the same as my old gingerbread. So sitting around waiting for ur official ics fir ur country is useless. Do what i did, flash cm9 rom and feel ics like google intended it!

Got my Galaxy Note...but...

Hey Guys I got my galaxy note today! it's awesome!!!....but...I immediately tried to check for updates... but after agreeing with the terms and conditions, it says "Registration is failed. Try Again?".
How can I get around this and update my device OTA?
Here's my phone info:
Model: Galaxy Note GT-N7000
Android: 2.3.6
Baseband: N7000XXKK5
Build Number: GINGERBREAD.XXKKA
have you tried installing Kies on your PC, then connecting the Phone via cable so that Kies can update it?
4.0 isn't available through OTA atm so you'd need to do the Kies thing

I'm doing that right now! Thanks! ... I guess my Galaxy Nexus habits are hard to break! LOL!
Sorry to hijack the thread but I also got my G.Note, but yesterday . Got it from Amazon Germany, and as soon as I took it out and connected it to the Wifi Internet it said that it had found the OTA update for the ICS.
I cancelled the update as I was not sure if it was worth it. I hear so many people saying that Gingerbread runs smoothly but that ICS is a pain. I also hear about all the camera bugs, etc that ICS has.
The question I have is: Should I keep with Gingerbread for a while longer or should I just update to ICS?
Thank you all for your advice.

I have tried Criskelo ICS, CM9, Stunner, Liquid Smooth and various GB roms. Even though I like some features of the ICS rom, I eventually settle for Chrack GB rom. It run smooth with good battery life and I have no problem runing all the applications I needs. I suggest that you use your GB rom for awhile before trying to update.

there were several updates to note (at least on mine, Base/Eplus Contract btw)
before ICS, and since ICS is not yet available OTA i think you can hit update on your phone until there are none left, then you should have the most recent Gingerbread version.
for ICS, see last post: Kies update^^
Sadly i already did the Samsung Kies update to ICS and now i have some battery problems (google cloud service and several other Wakelocks draining like a *****)
apart from that little problem ICS is working fine
Hi all and thank you for your input.
As for the last post from Aiphares, I can confirm that there is an OTA update for ICS for my phone.
If I hit update it says that an important 4.0 ROM is available and that it will be 316mb (if I remember it correctly). If I wanted to update now or later.
So I did hit later to see what your replies would be, as I did not want to be one of those asking for help how to revert to gingerbread because my phone could have horrible battery drain, or any other known ICS bug.
I would really like to have a working ICS on my phone, and hopefully something that would improve the S Pen, so that I could actually use it for my daily annotations (minutes of meetings, etc.).
Why can't Android battery just improve, I remember that from Froyo to Gingerbread the battery got much better. Well we can't have it all with these dual cores running in our pockets.
As for the custom ROMs I first want to try the official ones, and if I am am not happy with them, I'll read and read so to prevent triangles and than I'll try a Custom stable ROM.

Please do you people even read this forum?? If i was you and read all the threads about bugs (eMMC) etc. etc. i wanted to wait a bit more. Ok, you just might get lucky (or not) and wipe the phone ten times but if you're not prepare to go to the store and claim your warranty !!!
Please read the topics about bugs on ICS.

(thanks??)
good to know that there is the OTA update now,
well if you feel uncomfortable you can always wait it out, i'm sure there will be more ICS updates and bugfixes

Official Update to Android 4.1.2 on N7000XXLPT? S-Pen issues!

Hello everyone. I just brought an Note with BB.N7000XXLPT, Kernel/Build XXLQ3. Unrooted with Android 4.0.3.
KIES and OTA says I have latest firmware, but I read that NOTE`s latest firmware is Android 4.1.2.
How can update to official Android 4.1.2 without rooting? Is that possible?
Now, my S-Pen is not work correctly. Sometimes works, when I press hardly, but very rarelly. Touchscreen display works just fine. Is that a common issue, is pen broken or is because Android ICS 4.0.3?
I`m new on this, just pls. help.

Where are you from? Maybe the JB update isn't available for your country until today.
You can install a Stock JB Rom (one of the official releases) with PC Odin.
Install JB and test your pen again - then you'll know if it's broken.
10x for quick answer ThaiDai. I`m from Romania. And I think the update is not ready here (it comes very slowly from carriers).
Pls. can give me advices how to install latest official stock Android with Odin, without rooting (I mean, i hope kies and OTA still working after).
Links, tutorials or something?
I just tested s-pen with testing tools and is working chaotic.
10x in advance. Jim
Dr. Ketan's thread is the thing you need.
Follow the installation steps in 1a and 1b.
You can try XXLSZ from Germany (download links in his thread).
How about S-Pen, what do you think, is a common problem or is my S-Pen broken or an 4.0.3 issue. How can I fix this?
And btw, on step 1b says to flash an custom kernel (PhilZ) first and then flash stock kernel. This make device rootable and KIES and OTG will not be available? (Allshare and Radio too)?
I try all day to do something with S-Pen, but useless. S-Pen works time to time and need really preasure to write/draw something. Sometimes I hope not cracking the display with that high pressure. I read tons of threads but never find someone with this issue. Mostly have issues with to sensitive pressure and 2mm inaccuracy (present in my case too). Help pls?
Did you install another Rom and check S-Pen after this?
ThaiDai no. I just stay on stock 4.0.3 what comes with the device. I just can`t understand why bunch of ppl over internet has problems o Note 1 with to much sensitivity at S-Pen, an I haven`t it at all. I need to stab the display to draw a single dot.
Install JB and test your pen again - then you'll know if it's broken.
You should try this first - from lamenting it will not get better.
I`ll try somehow to test my s-pen on other device or some othe s-pen on my Note to test it. If I can`t, device has guarantee certificate and that`s why I don`t update to JB, temporary. Is very strange tho...
You don`t reply to my question. If I want to update to JB, need to install (PhilZ) first and then flash stock kernel? This make device rootable and KIES and OTG will not be available? (Allshare and Radio too)?
10x in advance ThaiDai.

And you don't read what is written there. No stock kernel but a stock rom is installed.
But why do you ask JB installation questions when you do not want to install JB?
So use your certificate and let Samsung repair your device or pen
I`ll do that. And if my problem is fixed, after I`ll try an JB Rom. 10x ThaiDai.
ThaiDai, installed 4.2.1 official germany stock via Odin and works great. This week I'm going to Samsung service to solve my SPen problem.

Solved S-Pen problem and now my Note with official kies Android 4.1.2 work almost great (a little exception with battery fast draining).

s5 rom to s3
Hy. Y flashed the rom on my i9305 and y had to reflash and then only I made the camera work flashing boefla.ok. but. Screen mirroring doesn't work apps to sd card the same and neither samsung link wont work. Are you trying to fix these? The rom is good. I have no complaints other that sometimes its eating the battery in5 hours. Thank's
S5 Elite for S3 (i9305) problem.
Greetings,
Today I was charging my S3 (i9305) and turned off the power. I later discovered that my phone was still on even though I had turned it off. I found out that when charging my phone with the power off it rebooted my phone. I don't know if it's a problem with the Rom or phone. Help would be appreciated. (I have attached a picture of what my phone gets stuck on before it reboots). Thanks.

Hi,
Im not sure but maybe this is the old bootloader issue..are you on new or old bootloader? and have you installed agni kernel that comes by default with the rom? cause i thought that the reboot issue only was present in the boeffla kernels for this rom, which i have removed from the rom thread some time ago, because they were not stable.
It is definately not a rom problem, cause im using this rom every day (btw im on new 4.4.4 bootloader) and i didnt had any reboots from the 1st day till this time also not with the 4.3 bootloader, using Agni kernel 4.9 everything works fine, even offline charging works, but from this we already knew that offline charging was working well on new bootloader.

It must be the Bootloader then, since I have already installed Agni v4.9. Would you be able to send me the link to the right Bootloader for the i9305. Thanks Maho.

Well the case is that the bootloader is not something you can find separately and flash it for example like a flashable zip, the only way to update the bootloader is by flashing 4.3 or 4.4.4 official firmware from sammobile.com or any other site where you can download samsung official firmwares, and it has the KNOX feature included which really sucks, therefore these bootloaders are also called KNOX bootloader. You can check what bootloader you have at the moment by booting into downloadmode and in left upper corner of the downloadmode screen if there is a line saying ´´KNOX WARRANTY VOID´´ means you already have the new knox bootloader and since the new Android 4.4.4 now there is also a line in blue color saying ´´SECURE DOWNLOAD : ENABLED'' which is the case with me.
If you like to update the bootloader you can do that, in my signature there is a link to ODIN guide, also there is a link in the guide for if you want to learn more about knox bootloader before you do anything, cause when you flash 4.3 or 4.4.4 official firmware the knox bootloader will remain forever with the device, its not something you can delete like an .apk file, the bootloader is part of the device structure.
This knox bootloader seems to cause problems with installing custom roms or applying root etc. (not for everyone though) but im now KNOXED for some time and never had actually any kind of problem installing custom roms or rooting etc. besides that i think that our i9305 is now getting old and 4.4.4 is probably the last official update to come from Samsung, so it doesnt really matter to be knoxed or not knoxed at this time IMHO and most of the people dont care anymore about warranty being void, but if you like to avoid such small issues like device rebooting by itself or any other issue caused by the old bootloader with 4.4.2 or 4.4.4 custom roms, i recommend everyone to update the bootloader if you plan to run 4.4.2 or 4.4.4 custom roms as daily driver.
If you are still not sure about this or you dont understand something, you can always look for more info in the general Q&A thread or just do some research on the internet.

Hey man sorry for late reply.
I think wifi direct isnt working then, for the audio skipping i think its related to your kernel settings, try other governors for example. I dont have this issue, music playing fine with me.

My Samsung J7 Prime doesn't have the update - Can anyone suggest how can we update it

My Samsung J7 Prime doesn't have the update - Can anyone suggest how can we update it to new OS.?
Currently, I had Kitkat OS.
Houses For Rent in Rawalpindi Graana
The J7 Prime was launched with Android 6 (marshmallow) - how can it be on KitKat 4.4 ???
Are u sure about your phone is original? U are from Pakistan? This should be G610F or G610DD.

Download the firmware for your phone model from here - http://live.samsung-updates.com/
For example here is the model F list - http://live.samsung-updates.com/index.php?device=SM-G610F
Search how to use Odin and flash the most recent.
You don't need root to do this.

1. You can try any region you want. Better install TWRP first, as described below. Choose language from settings. Region gives only some CSC (Google it) features.
2. To flash custom kernel you need custom recover, like TWRP.
3. I don't know.
4. Depends on what you want: stock with Odin, custom kernel and ROM with TWRP.
As an advice - read a lot to learn before you do anything, to be sure you understand what you're about to do. It's on your responsibility of your own actions. Every phone is unique, what works for me may give you issues. It can be the other way around too.
Best thing to be sure is to have TWRP installed, backup the EFS and the system at least. If you read about this, you'll understand why it's very important.
Then you can try to flash another ROM custom or official.
Then you can test the new ROM, see if you like it. Leave it for a few days so that the adjustment of the kernel is OK. If you don't like it, you can always go back and flash the backup ROM from TWRP.
Also you may use the Smart Switch for PC to downland the original latest firmware for your phone. Search on how to use this program.
Good luck.
thanks man. i appreciate your help.
