[Q] Rogers Skyrocket ICS downgrading - AT&T Samsung Galaxy S II Skyrocket SGH-I727

So I started to read up on the new ICS update for Rogers Skyrocket, and the consensus is that it's slow and laggy. I do want to try it out.... but here's the big question...
If I don't care for it.... can I downgrade back to 2.3.6? With no relative issues?
And how would I go about doing it?
No0b question I'm probably sure... but hey if you don't ask you'll never know!

It would be best to back up. Back up creates a copy of your entire phone so you can swap between the two images if you'd like. If you really have important data then I would back up stuff to your PC first.

Im not finding it slow and laggy at all. But yes, pretty sure if youre gonna downgrade you gotta odin the stock tar from sammobile. Might be able to do it through kies, but im not sure

Its not slow and lagy for me. Works great. I upgraded with the sammobile tar installed cwm and rooted. You can always go back. Just install modem and rom or get tar from sammobile.

Well I am downloading a TAR from the site here that I found of 2.3.6 so that's ok... I've backed up the phone from Kies so I at least have a copy there... but for the most part I won't lose anything there either. Most everything I have is backed up on Google...
SO I guess I would jsut load the 236 to my external and then install it if i wanted to?

This is a question. therefor, belongs in Q&A. Moved.
Cheers

Hi, noob here (obviously)
I went ahead to downgraded my Rogers GSII LTE from ICS 4.0.4 to GB 2.3.5. It's the correct stock ROM, as I've used it previously without any problems.
I wiped all data while still on ICS, put the phone in download mode, launched Odin with the option "Auto Reboot" checked, nothing else. Pointed the PDA section to the stock ROM. Flashed it, and after about 4 mins it rebooted.
I get to the Android setup page but I can't even launch the setup.
"The process android.process.acore has stopped unexpectedly. Please try again" and it Force Closes.
Anything I can do to clean the phone properly to reload the stock rom?

No Worries PR.... Thanks for the heads up....
And I notice that it's laggy here and there... especially while texting. I've been using advanced app killer and seems to help a little....
Battery life has increased too which is a good thing. But all in all.... They fell flat. Lots of programs that just aren't ICS ready for the GSII

2.3.6 is not rogers, im guessing u r not rooted or have cwm, if u want to go back to rogers stock its 2.3.5 , u can use kohanes method but not his firmware files, go to sammobile to get the stock files, use i727r in the search box in the firmware section

strange ns4g issues

I used odin when the 4.0.4 official leak was posted here. I since uses the one click software restore back to 2.3.4. At first it gave an issue with the radio. On my phone while restoring it said "radio fail" but the phone seems to be working.
Now I manually updated the unrooted Sprint official 4.0. And my phone since the very first thing I said, has been randomly rebooting, I tried a different battery and it does the same thing. It's also real laggy. Any advice? Are there stock 2.3.4(7) files I can odin? I want it completely factory. Or suggest the problem? Thank you.

[Q] ICS_SMOOTHIE not working for me

Hello everyone, just got my skyrocket gs2 (from ios4s) and longstory short,
i was told (by att rep) this phone did ICS....
so now i know it doest for now.......so i decided to root(ok so far) and
all that jazz......
im up to the point where i drop in the rom on extcard to install.
The problem im having is that the ROM im trying to run is
ICS_SMOOTHIE
and its not working properly. When i install (about 5 tries already) all goes good till reboot. I reboot, phone "sammy text" appears 3-6 xs, then eventually i get the ICS intro with all the colors and 1sec after it appears, it freezes and theres like a "Mmmmmmmmmmmmmmmmm" sound like a turbine engine like if phone was gonna blow up.
My ? is, whats going wrong? i followed the guide to the letter and did every step(as far as clearin cache etc) multiple times.
if this rom is bad (i also downloaded twice) then are there more ICS roms
out there that r good?
Thanks in advanced.

Hmmm you did install the ICS leak first, correct?... if anything don't do darkside wipe and only clear cache and dalvik cache. Flash zip from sdcard and do factory reset then reboot.

OK I see your problem. Looks like the rooting guide you followed is for GB (GB is gingerbread OS) which is before ICS. And let me get you the right guide... u need to flash this first http://rootzwiki.com/topic/23105-i727ucld2/ and that is becuz the rom itself doesn't have what is called the "radio" or "modem" for it to work properly so u need to flash the ics leak that came out first and then you have to flash CWM TOUCH recovery with Odin and root... http://forum.xda-developers.com/showthread.php?p=24085665 rooting guide for ics: http://forum.xda-developers.com/showthread.php?p=24050465

Firstly, man, the devs will kill you if you say they are just skins and not full ROMS..LOL...!
The step above in your post: You should not skip that step if you are coming from Gingerbread.
You flash the leaked ICS modem first thing.
Then you wipe data etc.......although the modem is onboard the ROM.
see mhx's Full Bloat ICS here: http://forum.xda-developers.com/showthread.php?t=1570498 FOLLOW THE STEPS AND LINKS FOR MODEM, KERNEL AND ROM in that post.
I have this running on my phone full time. I think that is that absolute safest for any newbie. Once you have ICS STOCK running, then you know you are good.
LMAO at all of you.
Thanks for all you guys help. i gave up and returned the phone lol, got a iphone 4s.......................( booooooooooooooooo ) lol
BUT, my quick question here (before i get stoned ) is lol, can i use these ICS "roms" on my galaxy tab? (im still a supporter) lol...
overall, i have samsung galaxy tab 8.9 and 7.1 and im wondering if i can use the tools you guys have provided on those 2 devices or if i have to go look for specific mods/upgrades for those devices seperately?
lol, thanks in advanced

Just updated to official ICS from Rogers

hey guys,
hope everyone is having a great weekend, i was so pleased to find out that rogers finally released the official ICS update for my galaxy s2 skyrocket lte, so i get it updated today.. and one the TW launcher is so ugly and non customizable and worthless so i am in the midst of deciding on one that i like, so far ive tried ICS pro launcher. my main problem with my phone after upgrading to ICS is the fact that the swype typing is so slow and laggy you can barley hold on a conversation, it just seems like ICS slowed down my phone a crap ton, and mind you i have not rooted my phone at all nor have i ever installed a custom rom on this phone, what do you think could be the problem? the phone itself is so laggy, anyone have any ideas?
Thanks in advance.
-Davey
just to reiterate i did the update over samsung KIES, am i supposed to do a hard or a soft reset?
Maybe you should give other launchers a go, I use Apex myself, but Nova is also pretty good for ICS.

factory data reset is the best way just boot up to the default androdi recovery (same way as you would with CWM) then clear data/wipe. Then you want to disable all that crap rogers installs on our phones (stupid one music, one contacts bs) and other crap that samsung installs on our phones. In my opinion CM9 is much faster and better then the ICS rogers rom.
EDIT: I got a brand new replacement for my i727r so I didn't want to root it yet cause its in mint condition lol so thats what I did to keep the stock at decent speed
When ICS will be available for at&t I will format the whole phone in CWM then flash ICS tar in Odin...That way did a great impact on ICS speed when I was using Nexus s...OTA over the old gingerbread was slow as hell, but when I did a clean install from scratch phone was way faster...and even better battery life ..I never really liked update rather than a fresh install in any software matter...

Kies is a very stupid software full of bugs and slow ..Why you need it anyway ? you can backup your pics files ...etc... using the USB connection , other things like contact are already on your google account ... So I don't see what kies is important for ...
----------
Grab the official Rogers ICS tar from sammobile.com and ODIN it to your phone...(that's after you wipe/format every partition (cache,data,system) in CWM recovery)...

[Q] Would Samsung fix my bricked phone?

I bricked my unlocked Captivate (bought on Amazon for $240 - I was avoiding a data plan) trying to get Ice Cream Sandwich on it. The phone was rooted.
Initially, the phone was only loading a Samsung splash screen when I tried to get it into normal mode. However, recovery mode was working; it would boot into Clockworkmod. Which is a bad thing considering they would easily tell I had messed with it!
So, I loaded the phone into Download mode and tried to flash the stock ROM using Odin. Odin said "failed" and now my phone was completely soft bricked, and the infamous "[phone]-----/!\-----[computer]" screen was showing up. Download mode worked though. I tried to flash all types of stock and custom ROMs to no avail. Now, recovery and normal modes don't work while Download mode does.
So, I called Samsung and told them it wasn't working; they told me it was still under warranty and I could send it in for repairs.
My question would be: will Samsung repair my phone, or will they find out I messed with it and refuse to do so? Also, if they find out, how much will I have to pay them to fix it?
Getting a new phone is out of the question... I might just buy
If there is an odin flash counter on download mode, they will figure it out if you have messed with it. If there's not, make a good story. Was it on 2.3.6 already when you bought it?
If you can get into download your not bricked. The screen you see is kernel panic. You will have to flash a proper kernel to get it to boot back up.
Sent for a corner cell in Arkham
Yeah, you can still fix it. No need it to bring to samsung
Has anyone sent a bricked phone in to Samsung before?
I tried flashing stock Captivate Gingerbread kernels to no avail. I googled and googled, and I tried everything I found. Including Odin and heimdall.
It was running Gingerbread 2.3.5 when I updated it myself to Ice Cream Sandwich 4.0.3. It was running beautifully. Then I tried to recover my backed-up data, which worked, but then I tried to reboot the phone and it wouldn't boot.
And no, I don't remember seeing any "flash counter." Would they still be able to tell?
Has anyone sent a bricked phone in to Samsung before? If so, what were the results?
Also, how much do you think Samsung would charge me to fix it if they found out and voided the warranty? Hopefully less than $50? And they would charge me for shipping too, right?

You recovered your apps thru TB? If yes, Didn't you read that you're not supposed to restore apps from titanium from GB to ICS? Might cause problem like this. No flash counter, they're not gonna notice this. Have you tried flashing again stock GB rom?(not just a kernel but a rom) And when you flashed that GB kernel, was that after you flash an ICS rom? Remember, when you're on ICS, you must use ICS kernel and not GB kernel. If it didnt work Just make a good story! Tell them you updated it through kies and updating was interrupted. Im pretty sure 2.3.6 is out on captivate. If they tell you its your fault for updating it, ask them why did they put update on kies when you can't even use it. Plus, they didn't warn you not to update it.

No, I used Clockworkmod to recover data. It worked, and then I hit "reboot system now," and the phone wouldn't boot.
I already shipped the phone off, but thanks for the help, I really appreciate it! If Samsung doesn't fix it I know what to do now!
Ok, so I've been doing some research over the past few weeks and I figured out what I did wrong. I inadvertently tried doing a Nandroid restore (i.e. - restoring the whole system) instead of just apps. And I didn't wipe data first. That's why it was failing to boot. Why I couldn't flash the stock kernel from Odin; I have no idea.
As for the phone; Samsung fixed it free of charge (all they had to do was a reset...) and sent it back to me.
After getting it back, I rooted and installed Clockworkmod recovery using Corn kernel version 7.05. Geeve420 has an excellent guide over on androidforums.com. Then I flashed Cyanogenmod9 RC2, then Slim ICS version 4.2. It's running smoothly, though in 24 hours I have had 1 freeze (I did a battery pull and restarted) and a few force closes.
I also installed that Google Now app (the thread on XDA is called "The Google Now for ICS Project"). In other words, I went from being a complete n00b to getting JellyBean software on my phone! All I did was follow the directions, step-by-step, and it worked.
Thanks to all who helped!

[Q] Help! Want to restore to factory settings from Leaked Android 4.0.4 UCLE2

Hi!
A while back (before ICS came out), I really wanted to get ICS on my phone (AT&T Skyrocket) and so used the instructions to put 4.0.4 UCLE2 onto my phone. These days I seem to have less and less time to play with my phone (sad) and so I want to just go back to the factory settings with the AT&T version of ICS.
My phone is no longer rooted but does have some CWM version on it still.
Can someone help me figure out how to get back to the original AT&T settings?
Thank you so much!
