[Q] Downgrade to 2.1? - Galaxy S I9000 Q&A, Help & Troubleshooting

Is it possible to downgrade from 2.2 to 2.1? I upgraded to 2.2 yesterday and now the phone is very sluggish. In 2.1 Launcher Pro was smooth as a baby's bottom and now it's not.
After the upgrade I did a factory reset, which I've read would solve a lot of problems.

Same problem
I am looking for the same solution.
Since I upgraded my galaxy s to 2.2 using odin3 I've got a lot of problems on the phone now. The Swype doesn't work Internet keeps crashing and the operating system crashes too. Google voice speak is also not working.
I've heard the only option is to re flash it but I don't know how to reflash or downgrade it to 2.1
Please let us know. My basement got changed to jp1 after Odin3

Most problem is old settings from 2.1.
The easiest way is to do a factory reset. Wipe the catch and format the internal sdcard.
If that works you can put back your app. Don't restor any old settings.
The other way is to make sure the phone is clean and flash latest firmware with odin.

[Q] How to go back to 2.1 Eclair

Hello fellow samsung users i needed help to figure out how can i go back to android 2.1 factory settings when i got the phone. I am currently using the beta version 2.2 XJP2 kernel 2.6.32.9 build Master 332 test keys 332.
There are a lot of issues while running this version, too much lagging, the device hangs up and restarts.. any help is appreciated.
I had froyo 2.2 jph installed trough kyes and went back to stock jm8 by flashing it trough odin. Then installed over tayutama rom. Cleared cache and data at first boot. I hope it helps.

[Q] unrooting and flashing new rom

So, basically, i got my galaxy s today... quickly tried some stuff, and i pretty much like it so far. But i do have some questions about unrooting and flashing.
1. Its currently branded and its eclair 2.1, should i flash an official generic froyo, or some custom rom like doc froyo 7.6.2?
2. If i were to root my phone, would i need to unroot it before flashing new rom? If so how would i do it (is factory reset enough or not)?
3. Which lagfix should i use after updating to froyo, that would be pretty easy to use and not cause data corruption or something like that?
Thanks.
no need unrooting since flashing will probably erase everything (os data) : )
just make sure to remove or disable lagfix bfore flash.
i tried flashing froyo jpo 2 days ago and forgot i have voodoo lagfix.
i had to factory reset(app data) bfore my phone booted : (
First if you move to froyo from eclair then you should do a factory reset, wipe the cache and format the internal sdcard. Do a backup before you do it.
Then you install all apps you want.
do not use any old data/settings.
They will corrupt your system.
Z4mod is a safe and good system to use for lagfix.

Thanks.
I flashed to:
PDA: XWJPA
PHONE: XXJPP
CSC: XEEJP4
This release isn't some sort of a beta, or a leak? I'm really all new to this, and just want to make sure i chose a right release.
It seems to be the right one.

Thansk for the reply. I will do it tomorrow. I am new to android, I hope all goes well. Will update my results.
OCLF is so 2k10

Don't forget to remove the ext2 tools after disabling lagfix.

The only time my phone has ever been on lagfix is when the ROM I flash comes with it. I really don't see any difference at all in performance with or without it. The only reason I'm not on GB is because I had TONS of problems with apps working and got fed up with it. If my signature still says KF1 then its old. I'm on XDA app so I can't tell.
Hello All, Finally I updated my Captiavte with Andriod 2.2 few days ago. I was not able to do that before because of some issues."
I un-lagfix my mobile and used Odin3 v1.0 to flash "I897UCKB1-homeBinary.tar ROM...
I feel now that my mobile is slower then before... But got some new features.
Can anyone tell me difference between "I897UCKB1-homeBinary.tar" and ''I896UXJL1-stock"?

4 letters. I896 is a canadian Captivate. No idea what jl1 is (2.1 or 2.2).
Hello All,
I applied lagfix on my android 2.2 OS and wow!!! speed is now 200% increased!!!!
Is 2.3 available for captivate ?
Many flavors of 2.3, just be sure to read the installation instructions and understand GB bootloaders before trying.
2.1 to 2.2 to Black Screen to Semi brick to Working Captivate...
Hello All,
I had some heck of the experiences in last 2 weeks which I would like to share.
-> I had successfully updated my captivate from Android 2.1 to 2.2. Using "I897UCKB1-homeBinary.tar" ROM from BriefMobile site. After this update my three button combo for entering recovery mode stopped working. I could only go into downloading and recovery mode by using Android SDK.
-> And as written in my earlier post, I felt that speed is slow so i "lagfix"-ed it. This gave very good results and all was working fine...
-> Until one day... I was installing blik calendar widget after downloading it from site(I don't remember link now)... This installation never ended, it was continuing even after 15 mins so I used Task Killer to kill the installation... After that it became very slow... I restarted the mobile and what the hell!!!! mobile was stuck at boot screen... Mobile was stuck at "S" logo.
-> I tried all the combos I could find on net to enter into downloading mode but none work. Computer was not recognizing captivate while it was stuck as S logo.
-> After few days I used USB JIG method to bring my captivate into downloading mode.
-> Tried to flash earlier installed ROM "I897UCKB1" via Odin 3. It was successful but now after boot animation I was getting black screen. Lights on button were glowing on pressing and mobile was vibrating but ... It was in useless state.
-> Tried to flash "I896UXJI2" ROM, same condition as above.
-> Then I tried to Flash "I897UCJF6-final-OCD-REV0.zip" downloaded from xda... with repartition option checked. It stucked in between and i had to remove battery.
-> Now mobile was in Semi Brick state.
-> All this time mobile was "lagfix"
-> Then somehow I got back my captivate using :
http://forum.xda-developers.com/showpost.php?p=7614957&postcount=6
-> Now captivate is working find but still 3 button combo is not working...
Which ROM should I use now to upgrade to for 2.2?
Is custom ROM better? Cognition !!!
Should I install ClockworkMod Recovery?

First, if you are at stock 2.1 eclair, you can use the 3-button odin one-click. As long as you have the eclair/froyo bootloaders, that will work properly. But for the love of all that is sacred and captivatible, make 100000000% sure you have the proper bootloaders first. Flash back to stock eclair if necessary to make sure of this. I cannot stress this enough. If you do not have the eclair/froyo bootloaders in place before using the 3-button fix, you will murder your phone. It will die, and you will most likely have to pay real money to get it fixed. Make sure you have the eclair/froyo bootloaders before using the 3-button fix.
(Sorry. I just wanted to make sure that you avoid an all-too-common issue on the board.)
What may be a better option for you would be to upgrade to Gingerbread. Part of that upgrade process will flash the GB bootloaders, which will automatically have your button combinations fixed.
In either case, there is some level of bootloader flashing involved, which does mean some level of risk - make sure to read up on it thoroughly before you do anything.
And custom roms, in my opinion, are always better than stock. Clockworkmod Recovery is something you'll definitely want to have (and is usually included in the kernels that you'll flash along with custom rom upgrades).

There are several roms that I897 GB based right now.
Like Atomic Fusion 1.5 and Cog v2, both are awesome roms.
Both will be developed even further, when source comes out! (The Official 2.3 update from ATT)

jst flashing Oden to Gingerbread

ok is it possable to just flash ODEN to flash gingerbread and not flashing a rom
is there any reason that it wont work
What ??? Please re-phrase ur question in a more clear way. Thanks
But i will give it a try...
You can flash any of the "leaked" or official Gingerbread firmwares (that are pure "leaked" or official stock) through Odin. Just be sure to flash the GB Bootloaders through Odin first, if they are not included in the firmware that u choose to flash. .This may be the answer u r looking for from ur question above...
.
Yes it does
The wife's cappy keeps freezing up and I don't want to flash. A rom just update to gingerbread to see if that fixes. It. And I might. Flash my infuse to gingerbread.
Is it freezing with a 1 click? Are you running Odin in admin. Are you connecting your phone to the rear usb port in the desktop?
No she running otb froyo with the go launcher and even running the regular launcher it locks. Up and she has to pull the battery to reset it
Factory froyo could use Ext4 format to help it out. Have you tried wiping the phone? How many apps/ widgets does she have open at once?
I was just in Froyo and my phone was beginning to lag and run kinda rough. I was weary of flashing because I dont know too much about it and I could afford losing the phone. However, I decided to factory reset (will lose info) and go for the One Click Odin to GB 2.3.5. I cant tell you how much I feel it improved my phone. It was very easy to do(Open Odin, Connect phone, click Start, Done!). Perhaps you can try factory resetting to see if your phone responds and if you feel like you want more, go for GB.

[Q] Possible to have infected kernel in GB?

Hey guys;
Started on Aussie firmware. Flashed to rootable UK GB, but the thing updated to the new ICS, which I know has an unsafe kernel.
I then rooted using dr.ketans method, and I also installed clockworkmod.
Since the kernel was unsafe, I then reflashed the UK rom and tried to skip the ICS update (no luck), but when it installed everything kept FC'ing.
I did NOT perform any recoveries or wipes!
I flashed to a generic, prerooted GB, but everything kept FC'ing. I couldnt access anything. I then flashed back to stock Indian rootable GB, which didnt auto upgrade to ICS. It was fine until I turned the phone off then back on, but now it is doing the same FC thing as the prerooted rom.
So far, I have only used PC Odin (using the single PDA mostly). I also havent performed ANY wipes (I still have all of my contacts and apps from the original Aussie stock). I stuck to Odin because I was told the eMMC bug from my faulty ICS wouldnt be triggered.
I guess the FCing has something to do with not performing a wipe and changing the firmware like 10 times. Unfortunately, I cannot access the *#1234# because the dialler wont work at all.
Bottom line: If I am on stock GB by flashing through Odin, is there still a chance I have an infected kernel? Also, I imagine my best way out of this would be flashing the prerooted ROM and performing a wipe, before moving to something like Paranoid?
Jesus Christ.
Thanks guys,
Vincent.
Edit: Settings is telling me the kernel version is KL3. Guess its safe?
Only official ICS kernels are affected by the emmc bug so unless you are on a LP* rom/kernel you're safe to do a wipe/factory reset. It will most likely solve all your fc problems.

As chasmodo said that wiping in gb again and again even your arse it will not bricked your phone. If you use the latest mobile odin there a data wipe you can check before it install a new rom try it.
Probably. Non wipe gb rom, leaving many ics stuff that messes gb up.
Migrating from ics to gb, go search on that

I am assuming you did clear cache and dalvik cache before installing a new rom, that's OK, just not to format system or do a factory reset if you are using a kernel that suffers the emmc problem...
If you don't clear cache and dalvik cache then you will have fc's...
Hey guys:
Ended up flashing Abyss, wiping everything, then CWMing paranoid. All good now.
You guys are terrific, I guess this can be locked now? Thanks again!!!
