[Q] Not sure how to downgrade Galaxy S from ICS to GB - Android Q&A, Help & Troubleshooting

Hi,
I bought a Galaxy S GT-I9000 (Bell Vibrant, I believe) and he has this version of ICS installed on it. http://forum.xda-developers.com/showthread.php?t=1649345&page=12
I want to downgrade to Cyanogenmod 7 simply to get a bit more performance out of the phone. But, i'm not sure exactly what I have to do, to accomplish this.
Android Version 4.0.4
Baseband: i9000UGKG3
Kernel 3.0.8-Semaphore_ICS_1.2.2
Build Number GT-i9000 4.0.4 IMM761
Mod Version ICS_F4k_MOD_V4.0.4_r3
Do I have to find and install a new kernel? The one I have says ICS, but i'm not sure if that will work for Gingerbread too or not.
Any help would be appreciated.
Thanks,

WEll, to makes things worse, I followed the advice of someone from this forum http://forum.cyanogenmod.com/topic/...n-mod-on-phone-that-is-already-rooted-at-404/ and now my phone is stuck in a boot loop.
Crap, now i'm not sure what to do.

Flash a firmware with 3 files PDA, MODEM and CSC using ODIN. If you don't have a firmware with 3 files, download this http://androidadvices.com/valuepack-update-samsung-galaxy-face-unlock-i9000-xxjvu-236/3/ and then update to a newer firmware like JW4 or JW5.

Ok, just to clarify something before i do this. my galaxy S is the international one, not the T-mobile vibrant, will this guide work fine for mine?
Thanks,

Thanks, I flashed over the all the files and was greated by the default Gingerbread theme. Flashed over to Cyanogenmod from there with no issues.
Thanks again, worked great.

Sorry to hijack a thread, but can this be done on a Moto Droid Razr?
I did the OTA update to ICS, and can't stand it. Want to go back to GB.
Any options? Or is this being worked on?
Thanks in advance.

SCH-I500
Firmware Version
2.3.5
Baseband Version
S:i500.04 K.EI20
Kernal Version
2.6.35.7
Build Number
SCH-I500.EI20
I am wanting to completely root my phone and install a clean slate of Gingerbread on it.
I've tried Z4Root, (I was able to root my phone with it back in 2.1), and have also tried Super One Click.
Nothing works now that I have Gingerbread and I can't find anything TO work.
I am praying to the xda gods for their wisdom and knowledge to help me with this problem! I have been at this since 9AM, it is 2PM. What can I do??
i dont use sgs, but i do know cfroot kernel or any other kernel based on cfroot can help u out.

JollyRogersOne I have the same problem If you find a way please let me know.
Same Problem
If anyone comes up wit a good link or video that will be very helpful
I have this same phone and took a look at the links in the second post. However the kernel numbers don't seem to be following the same format as the links in the thread.
Has anyone had any luck rooting this kernel on the c spire galaxy s showcase?
I tried Odin3 and it messed up my phone and I had to go get a new one.
I'm also looking for help on this as well.
SuperOneClick
I'm having the same issues. I have tried SuperOneClick and it stops on step 6.
I'm having the same problem too after updating to 2.3.5. Super one click freezes on step 6.
Same issue with my CSpire SGS running 2.3.5. I do think that speed and battery life are improved over 2.2, but I miss my root.

If you used Odin, I doubt that it messed up your phone. What did you try to flash with Odin?

Did you guys do the official update with Kies? Send me a PM for a way to get a rooted ROM on your Showcase.
I did so the official update from C Spire. I'm not interested in a custom rom I just want to root my phone so I can use wifi tether with my galaxy tab again.
Any help would be appreciated.

I've ran several custom roms on my phone, but would like the option to just run stock with root so I can remove all of the bloatware from CSpire.
I've also had various issues with some other roms, ranging from no auto-rotate to glitchy in-call audio.

Cannot figure out adb.
I've tried all things to reroot after gingerbread update. Now I'm here to try this method. I cannot however figure out the command process. Can someone please be a bit, or a lot, more explanatory. I'm probably the most noobish person here.
Thanks!

This worked great. I did have to reboot (as you always should...I just get impatient sometimes...) to get everything flowing smoothly. It scared me on reboot because I thought it was getting hung up, but right before I pulled the battery it went to the screen lock. Phew.
Thanks guys!
Im not able to get Odin to recognize my phone. Is there another way?
I suck at this. I want to root my phone but can never do it right. I have the C spire Samsung Galaxy S with 2.3.5. Can you please help... email me please, [email protected]

[q] gt-i1900p i9100xxlpb

Hello,
I just purchased an GT-i1900P orange, UK
Can i flash it with for example "I9100XXLPB" 4.0.3 ??
I know that I will lose NFC and I do not care.
But is it possible? or I will brick my phone?
Any help is appreciated.
Many thanks

Yes, it is possible. I9100 ROMs will indeed work on I9100P phones, but NFC won't work anymore... and it sounds like you already know this.
It's ALSO possible you can also brick your phone if you don't follow instructions.
ALL THAT SAID... If you are concerned about stability and NOT bricking your phone, then I suggest you do NOT flash ANY ICS based ROM, as it's not yet been officially released. That means any ICS based ROM is built off a leak, so stability is NOT guaranteed.
thank you for the explanation. I appreciate it.
by the way, even the radios(modems) are compatible/flashable?
god of war here I come..

Hi,
I also have the GT-i1900P Orange UK version.
Can you tell me which ROM did you flash? I need to debrand that Orange stuff since I'm on giffgaff. Would love to have some latest generic Samsung firmware but I'm a bit lost when it comes to ROMs. So far I've managed to remove simlock using Samsung Galaxy S unlocker and flash "CF-Root-SGS2_XX_OXA_KI3-42-v4.2-CWM4.zip".
Thanks

You can flash any I9100 (NOTE: NOT an I9100G) firmware. Just know that you'll lose NFC if you do. But it looks like you already got this information in a different thread.

The first thing anybody should be doing after rooting and before flashing an ICS BETA ROM is making an EFS backup(download release.zip)
http://forum.xda-developers.com/showthread.php?t=1308546
and then making a Nandroid backup just incase you need to get back to your previous Firmware.Without these 2 things you could loose your phone cos your flashing a BETA ROM.
EDIT:A good kernel for ICS is LP6 as LPB seems to have more bugs in some ROMs.

Hello,
I have done exactly as you did. Just that I also backed up my EFS!! If you screw your EFS that you screw the phone so better safe than sorry.
Then I went on flashing I9100XXLPB with ODIN (there were three files).., the same way you flashed CF-Root-SGS2_XX_OXA_KI3-42-v4.2-CWM4.zip
So far so good! on 4.0.3 , performance is great
got 4027 on quadrant benchmark
absolutely no crashes yet..
thanks everyone for the help...
it seems easy now once you do it yourself..

[Q] How do I root and install cwm with the ICS update?

So...I returned my phone to stock, which was a nightmare because I already had a devs ICS and the instructions (for returning to stock) are for UCKH7...got endless errors and whatnot...
Finally figure it out. So now I'm back to 2.3.6 and I figured I connect to Kies and get the At&t ICS version. No problem...got it!
Now...if I want to root it and instal cwm, how would I do it? I mean the methods at the dev section are for the gingerbread os, right?
Any help will be appreciated. :good:
just flash a kernel with Odin. Far as I know it should work fine. Then again I haven't had to do it for a long while.

If I were you I would stay away from the At&t ICS version read this thread....
http://forum.xda-developers.com/showthread.php?t=1757972
This is MUCH safer read this thread.....
http://forum.xda-developers.com/showthread.php?t=1650948
EDIT: After a little more thought if I were you I wouldn't do anything else to your phone since you already flashed the kernel with the 99% confirmed eMMC "superbrick" bug (see the first link) until you research the best way, least possible chance to bricking your phone... Maybe Entropy512 can help with the best way to flash a new package!! GL if anything ever did happen I sure hope Samsung would give you a replacement.....
Another question (might be related)
Hey all,
I have just got a brand new i777, I just wanted to upgrade it to ICS and sim-unlock it.
The upgrade is to be done through kies, no problem in that.
The sim-unlocking is the issue .. i know it was easy in gingerbread to root and use herlroz app .. but now is there an easy way without using ODIN or flashing a kernel to sim-unlock this phone on the official ICS ?

[Q] Which ATT modem Do I Use?

I have the AT&T radio files for the Galaxy Note SGH-I717. I don't know which files to use for ICS, since there are no instructions included. There are MODEM.B00 - MODEM.B10 files (which one is for ICS?)
There are MDT files & Q6 files. I have absolutely no idea which one I would flash. I have the AT&T zip file stored on my /sdcard on the cellphone. Please help.
I have installed Padawan 8, but I want to go back to ICS so I can unlock my AT&T-based phone.

Okay, I have no clue what you're talking about, at all. So whatever you've done up until now, and whatever resources you've used, stop.
UCMB4 is the last modem released for ICS, and it's perfect for AT&T and T-mobile

[Q] Telus i717D

Ok got a question?
First off I am by no means new to the android dev community as I have developed a rom for the sgs-II for At&t before my when in the toilet, anyways I am now on a Telus Samsung galaxy note I717D running:
Android 4.1.2
Baseband Vers. i717dTLMD1
Kernel Vers. 3.0.31-1112295
Build number: JZO54K.I717DTLMD1
TWRP RECOVERY
The phone is not rooted as far as it tells me however I am able to flash any rom I want through twrp recovery. anyways I am using tmobile sim
the question is this has any one flashed a tmobile or at&t modem/radio onto a Telus phone with any luck? if not any recommendations on getting better signal cause mine is **** at this point when I switched my sII to tmobile my signal was pretty decent not the best but still good.
Ok so after a couple of days and np responses i guess i am off to expirment city and will try what i ever o get my hands on and will report back to let others know

Hi there,
From my understanding of your comment you're trying to root your phone correct? If so, I can suggest you check http://www.kingoapp.com. The reason why I suggest it is because it's pretty easy to do; it is how I rooted my i717. Check it out and if you'd like try it.. it's kind of like a one click root way to go about rooting your phone, if you'd like to try obviously.
Cheers,
