SGSII: Any idea on update to JB?

I know this may be impossible to answer, but does anyone know or have a reasonable guess about a JB update for the SGSII?  I struggle with the wifi connectivity issues and the battery drain troubles (due to device staying awake) of ICS.  I had the same battery drain issues with my AT&T SGSII when they updated to 2.3.6, and the only solution was to roll back to 2.3.4 until ICS came out.  I worry that it may be a long time, if ever, before the Sprint SGSII gets an update, so I am wondering if I should just root and flash.  Then again, if JB is thought to be right around the corner, I'll save myself the trouble and just be patient.

Also, is there any idea as to whether the wifi connectivity issues (shows connected to wifi but randomly won't connect to the interenet -- like it times out after a random time on wifi) is software based (and would therefore be fixed by flashing a rom) or whether it is hardware based?

Thanks!

  • I would check with the XDA forums.  http://forum.xda-developers.com/forumdisplay.php?f=1281 The XDA forums often get ROMs leaked semi officially from Sprint. It looks like there are JB leaked ROMs so you potentially could update using an unofficial ROM until the Sprint OTA ROM comes.

  • Root it and try some of the roms that are out for it.  Rooting allows you to do a lot more than flash roms.  Not having a backup solution that allows you to save programs and data is just nuts and you can't use the best (Titanium Backup) to the fullest degree without root.  XDA is the place to start.  If you have a choice, go with TWRP recovery.  Backup everything and go to town.  Do a Nandroid backup before flashing anything.   Read up before you attempt.

  • Saw on AndroidCentral.com that the official JB update was available as an optional update over Kies.  Check out the following link.  I haven't tried it yet, but I think I might.  Any ideas on whether this would work for a Ting device?

  • There is NO difference between a Ting device and a Sprint device. The update using the method outlined in the Sprint link should work just fine assuming that you aren't rooted with a custom ROM.

  • I just updated my wife & my GSII;  I first tried Samsung's Simple Update Tool, but that didn't work; it got stuck on the detecting usb port step.  So I installed their Kies program, and let that handle the update; that went perfectly.

  • I installed 4.1.3 on Saturday March 30th. I would suggest holding-off on this upgrade. My S2 now drops Wi-Fi, shows connected when it isn't, and more. It reboots constantly, and gets stuck in a reboot loop for 3-4 tries before finally connecting. It drains the battery really fast while doing this, too. Crashes when loading the Facebook app. Really, more problems than just these.  Be patient and just wait.

  • I said "reboot loop for 3-4 tries before CONNECTING". I should have said "before TURNING ON" The phone shuts down, then restarts, crashes, then tries to start again. BAD BAD BAD

  • Funny Brian, I had the exact opposite.  I was having wifi problems and poor battery life.  I wasn't having the reboot troubles, but everything else.  The update fixed all my troubles.

  • So now, if Wi-Fi is turned off, when I try to turn it on, the phone reboots...and starts with Wi-Fi enabled, but no icon in notification bar.  Yep... repeatable, not intermittent,

  • Turning on/enabling Wi-Fi from the Settings menu works fine; no phone reboot.

  • So, aside from the issues I'm having, I really notice how responsive and "snappy" the UI is. Very smooth scrolling and swipe action and quick screen redraws. I was envious of my wife's S3... not anymore!

    If this is the official Sprint JB for the S2 then you should try an ADB backup and Titanium backup of your apps and then to a factory reset. The update would not have gotten this far if the ROM was this bad.

  • thanks. That's what I did before the initial install. No problem. My after work project ;)  It's fun, and so much better than running iOS.

  • Just got my Galaxy S2 Epic 4g Touch (refurb) Friday and it came with Gingerbread installed - even though the devices page I bought it from stated ICS. When I run Kies it tells me my firmware is too old to update using Kies.  Any idea if using the simple upgrade tool will work any better?  I couldn't find an older version of Kies. Even the Samsung "ICS is available!" page links to the JB page instead. I'd like to get this upgrade installed since the ringer rarely works. Sound has only come out of the front speaker once - no ringer, music, or speaker phone. Since it did work once for a couple of minutes I assume it's a SW and not a HW issue. Head phone jack works though so does vibrate, which is how I would typically use the phone.

  • I believe the update from GB to ICS for the E4GT was OTA.  Have you tried telling your phone to look for an OTA update?  I also found this...it may help...

  • Yes I've tried to check for a system update. "Update Firmware" sates there is no update available, and "Update Android" states "your system is currently up to date".  The video looks very helpful, although mine is at EL26 not EL29 as in the video. I wonder if that matters much?

  • Yes, I think that matters.  You can probably find instructions on how to update from EL26 to EL29 out there too.

  • David,

    I just looked at the thread at  http://forum.xda-developers.com/showthread.php?t=1903252

    According to that thread, EL26 is a leaked GB ROM, not an officially released stock ROM. That thread also has links to the ROMs.
