How to Flash Android 4.1.2 KESANB1 on Galaxy Win SCH-I869
Galaxy Win SCH-I869 will work even better with Android 4.1.2 JB on-board. Which is why an update should be the norm. We describe the ways of this process in the upcoming paragraphs, so be sure to stay tuned!
There is only one firmware for your Galaxy Win SCH-I869 if you live in China. The firmware’s name is KESANB1 and it was released this month for the carrier called Anycall. The new OS will end up on the handset if it’s the Samsung I869. Apart from this phone, no other model should be used; or it will get bricked.
You shouldn’t use KIES for the update; it won’t work since the new firmware’s KIES logo is not turned on. This is the reason why you can select between this alternate methods: OTA (over-the-air, for which your phone must be complete with stock ROM) or the present guide (for which we don’t require stock ROM).
The Jelly Bean 4.1.2 and the stuff it updates your handset to via this new official firmware are detailed here. Your smartphone is going to end up with these first goodies: a new keyboard and mini apps. After that, automatic adjustment for the size of widgets and free style widget will land on the phone. Extended Vsync timing, triple buffering and all share continue the list of novelties. Sync and connect email updates is followed by Google Now and touch anticipation. More to come are pop up play, group cast and a fixed frame of 60 fps.
From the point of view of a rooted device, things don’t look good. The first to be affected is root access, which will be revoked; system partition comes up next: it will be deleted from the smartphone. The internal and external SD cards on your handset won’t get damaged. The device will not end up with lost data, either.
When you’ve learned all there is to know about the update, prepare the phone by following the requirements below:
- the Galaxy Win SCH-I869 should run with a fully charged battery;
- we need you to use a laptop that features only Windows;
- the phone needs to feature an activated USB Debugging;
- turn off the security programs pre-installed on the phone and the laptop;
- download USB drivers which fully work with the phone from here on your laptop;
- create standard backups as well as a full NANDroid one.
Step by step instructions
- The task that begins the guide requires this from you: prepare your notebook for the download of a few packages. These are their names: the Jelly Bean 4.1.2 KESANB1 official firmware for China and Odin v3.09, available on this page. WinZip or 7Zip will help you in the next step, which asks you to extract the packages mentioned before.
- After this phase, Odin v3.09.exe will come out, as will other files. You have the job of opening this file on the notebook.
- Then move on with this task: boot the phone in Download Mode by pressing and holding Home, Power and Volume Down at the exact same time. Let go once a boot message appears, then be sure only Volume Up is pressed.
- Once the Download Mode is displayed, plug the Galaxy Win SCH-I869 to your laptop through the USB cord of your handset. Odin will tell you when the connection is done by popping up a blue sign on the display.
- As soon as the connection is created, time to go and add the firmware file to the AP / PDA, after which this needs to be done: activate both F. Reset Time and Auto Reboot by checking them. Re-partition must be ticked off.
- Begin the installation of the update firmware like this: tap “Start” and wait. If 13 minutes are gone and the phone displays “Pass” in the usual green background, you will be close to ending the guide.
- But first, wait for the smartphone to reboot. After this final action ends, the Galaxy Win SCH-I869 will have the Android 4.1.2 KESANB1 among its goodies.
Open the new OS by tapping, on the handset, these options in this order: Settings and About Phone. This is going to help enjoy the novelties we presented earlier.
If they don’t look interesting, you can turn to the NANDroid backup file to restore the old ROM. The update procedure will then be revoked.
