Bootloops solution while downgrading - Galaxy S I9000 Q&A, Help & Troubleshooting

Hey guys I am very much pleased to share my solution when downgrading from a higher rom to a stock gb rom
I actually wasted more than half a day to rescue my mobile while I flashed stock gb (2.3.6) from a jelly bean rom
I flashed the stock rom via odin and still it somehow went into bootloops...
I searched and searched and viola!
1. Flash a stock gb ROM ( a JW4 is recommended) via Odin3
2. Reboot it.
3. It may get stuck at Galaxy S logo
4. Switch off the phone and put into download mode again.
5. Don't sweat it out as yet....There's still life in your phone.
6. Open odin and flash http://dl.xda-developers.com/attachdl/6b8a60703ecff287007bedbf951d050d/522c493a/8/4/5/2/8/3/dbdata.rfs.tar as PDA with nothing else ticked except Auto Reboot and F. Reset Time
7. Now keep your fingers crossed and set up your mobile.
Rooting (optional)
1. Once your mobile is setup
2. Switch it off
3. Open download mode
4. Flash this file http://download.chainfire.eu/155
And you can relive the stock GB experience.
Press thanks if I helped you... You'll be appreciated...

You wont get this problem when you flash JVU Firmware.
When you flash a rom for up/downgrading , flash it 3 times , then you won't get into bootloop or any other trouble.

[Q] Samsung Galaxy S stock rom flashing help

Hello,
I am completely new to flashing roms on android devices and i am just trying to understand the basics behind the process.
- Installing custom roms
- reverting back to stock firmware after installing a rom
I read the 4th post in this thread : http://forum.xda-developers.com/showthread.php?t=991792
i kinda have some understanding about flashing roms now but i still dont fully understand it.
My device is a Samsung Galaxy S i9000.
Thanks
What exactly do you want to know?
1. Installing custom roms is pretty easy the hard part is choosing the rom and to flash a rom you need to have the cwm recovery and like be on the base you need. ex: lets say you are on a jvt rom and you want to flash a jw1 rom, well in this case you dud need to flash jw1 from odin and then flash the rom from recovery...., but if you are on a jw1 custom rom, then in that case you can just flash the rom from recovery with wipe (recommended).
2. To flash back to stock: you dud need the stock file from sammobile or from wherever you get it and you would need odin, you place your phone in download mode then you put 512pit in the pit section/ code in the pda section/ modem in the phone section/ and csc in csc. then you have to make sure that repartition is ticked and all the others. make sure that the download is not interrupted for that would brick the phone.
-to flash a kernel you dud need to put the tar file in pda and Don't check repartition and click start.
I hope this helped a little
and remember to do this at your own risk.
Sorry for the noob questions but im just trying to understand haha
1. what are jvt and jw1 roms?
2. When you say be on the base you need do you mean the base firmware required for the rom?
3. How would i know which rom i have now, JVT or Jw1?
4. Whats the thing u mentioned whipe in "you can just flash the rom from recovery with wipe (recommended).?
last.5. I already found the stock firmware i have now and ive downloaded it for later if i need to restore it. but what is the tar file you mentioned in the end?
Thanks Man. I appreciate it.

sorry, this is not meant to be offensive but you have a lot to read. There're some good tutorials on how to flash your phone here on xda. search for it.
short answers to your questions:
1. jvt or jw1 are versions of stock samsung roms
2. I think he means if you are on a jvt rom you should only flash custom roms for jvt
3. settings>about phone
4. wipe means resetting the phone, deleting cache and dalvik-cache
no matter what u know u first should know about flashing stock roms..in case u mess something up u will need to flash the stock roms,its a good thing that u have already downloaded these..then u should know how to install kernels to root n have Clockworkmod recovery,then u will be able to flash custom roms..u should serach the net for these questions with a 'How to' at first...
Instruction for new ROM installation
There are basically 2 methods for flashing a ROM
1. CWM recovery menu mode
2. Download mode.
1. For CWM recovery mode you phone must be rooted with CWM, just put the ROM zip file in sdcard of your phone of your choice. then power off the phone. Then you may want to boot in reovery mode for this use pressing and holding 3 button combination simultaneaously as Volume UP + Home key + Power key now you should be booted in to recovery mode there just wipe data/factory reset then wipe cache from option then find and select install from sdcard -> chose file zip from sdcard and press power key to selct and start flashing. wait max 5 min and your phone will be booted with new rom of your choice.
2. Boot in to download mode by pressing and holding 3 button combination simultaneaously as Volume down + Home key + Power key now you should be booted in to download mode now connect your phone with PC and open odin in PC then select ROM file as PDA, PHONE & CSC under propoer boxes then click start - wait max 5 min and you phone will be booted in to new rom.

[Q] SGS debrand

Hey guys.
Just bought a brand new SGS on Portugal Vodafone last week. On first day, and after read some hours here in the foruns i already rooted it and unlocked it ^^
Now a question arrises, debrand the bastard!!! i hate the Vodafone animation on the start after the first boot logo that says Samsung Galaxy S GT-i9000, hate the vodafone bloatware that fuls the screens, and sincerely dont like the lots of Samgung App that sneeks around every corner of the phone.
Already flashed and debranded other phones so im not really a BIG noob on the thing, but im a really NOOB on Samsung phones. To be honest im scared with all the procedures that exists... Already backed up EFS folder for starting. attached you can find 2 screenshots i taked of the version and about screens
I can enter recovery and download modes and already noticed i cant install Clockwork Recovery ( is it the best here for the SGS, or stock one is suficient? ) because im at 3e version of android recovery and not 2e. id love to try the ROM MANAGER app...
So as im at 2.3.3 i guess i'll wait for a custom ICS, but i really would like to get ride of this bloatware, stock or custom ( i like cyanogen roms )... is there a soul that is willing to help me?
thanks in advance
Nuno
Hey,
seems you want try ICS rom. Okay here ya go:
1. First you want rooted ROM with CWM installed. Easiest way to do this is flashing a "base
ROM" like this: http://sourceforge.net/projects/ficeto.u/files/JVU/JVU-RE.zip/download
(Thanks Darky and Ficeto, http://www.darkyrom.com/community/index.php?threads/odin-jvu-re-gt-i9000.6558/)
2. Extract the files, you should have: Odin 1.3, .pit file and PDA.tar
3. Now open Odin, set .pit file
-tick repartition
-set PDA.tar into "PDA"
-put your phone to "Download Mode"
-make sure all is okay and your phone is detected by Odin (if isnt't, you have to install SGS drivers to your PC)
-click start
4. When flashed, wait until your phone reboots. (nice sound fx, eh?)
5. Now your phone is rooted and has CWM recovery.
6. Now download Teamhacksung's CM9 ICS .zip:
http://forum.xda-developers.com/showthread.php?t=1363593
-download also Google apps
7. Put your phone to PC and copy these files to your phone internal sdcard.
8. Go to recovery and wipe data/factory reset and wipe cache partition
-then install .zip from sdcard
-choose your zip
-flash
-when flashed, flash Google apps
-wipe data&cache again, or calendar sync wont work
9. If it goes to bootloop (wont pass samsung galaxy bootlogo) flash again.
If Google sync won't work, you have to install Google apps fixer from CM9 thread.
Hope I helped, ask if you didn't understand something=)
You are doing this at your own risk

Done, wonderfull explanation, all runned ok fine. im at 2.3.6 now on darky's ROM. I'll make a full backup with CWM Recovery to the SD so i can back always back to this step
Deep Breath, and here we go again, lets go eat an Ice Cream Sandwich
Very glad to hear all went okay!
Teamhacksung has released new CM9 build today, try it
Also, Codename Android has quite stable ICS build, and I think it's the most stable ICS build so far.
Welcome to ICS, it tastes good!

Downgrade from ics

I want to go back to gingerbread am rinning Dark Knight rom any help plz
Why God .. why ...
Flash stock through ODIN or Heimdall and thats it
If you had to ask this, it's probably a good thing you're going back to stock.
Sent from my Telus Fascinate running OneCosmics ICS!
why would you say that
Get stock ROM here.
http://www.sammobile.com/firmware/?page=3&t=1&o=1&m=GT-I9000&r=-1#modelsa
You need stock ROM (3 file stock ROM), Odin & Pit512.
1. Start ODIN.
2. Select the files into the relevant places in ODIN.
3. Click repartition.
4. Put phone into download mode.
5. Connect phone to pc.
6. wait for Odin to connect to phone.
7. click start.
8. wait for ODIN to finish & for phone to reboot.
You must have pit512 and click repartition as ICS uses a different file system to Gingerbread.
You may have a boot loop after doing this. I have had this occasionally. To solve this reflash with ODIN. This time make sure repartition is unchecked and don't flash pit file.
Sorry Screen shot says scs. I meant CSC.

ics install directly from stock??

Hello, I would like to install this rom:
[ROM][ICS][4.0.3][Milestone4]BLUE LIGHTNING- v1.1.1-BLACKeditioN[AOKP][16/3/12]
on a i9000 (Dutch) from a collegue. He is on stock rom, version:
eclair
xxjm2
2.1 update
I myself have installed the Blue Lightning on my own I9000; I have to say it's awsome!!!
developper of the rom states:
==================================================
--COMING FROM STOCK ROMs/SAMSUNG BASED ROMS-
*DOWNLOAD ROM
*WIPE DATA/FACTORY RESET.
*WIPE CACHE PARTITION.
*FLASH ROM.
*WHILE FLASHING THE PHONE WILL END UP IN A BOOTLOOP(if u have external sd card inserted, else wont reboot), NO PROBLEM.
*SWITCH OFF BY REMOVING BATTERY.
*REBOOT INTO RECOVERY.
*REFLASH .
*REBOOT.
================================================
Can I update the ICS directly from stock recovery??
Thanks in advance!
No. First you need to flash a GB rom that contains the GB bootloader. You can flash the GB bootloader by itself if you want, but it's generally not recommended (but I did it anyway).
thanks!
What is a gb-rom, and can I flash it without Odin? I.g. can I flash it directly from the recovery mode from stock rom?
I don't want to get in too much trouble by doing a fovour for a colleque.......
And I don't want to run the risk of bricking his device!
Thanks in advance!
GB is gingerbread ... 2.3.x-firmware. Take jw 1 or jvu
must do this with Odin, for the bootloader.
Then ics-ROM
Sent from my GT-I9000 using XDA
Can colleque first update with Kies to Gingerbread? So we can bypass the Odin-fuss?
Thanks!
You can flash this rom with odin so you have Gb + root
When you install the rom you can flash ICS directly
1. Download
2. Extract ZIP
3. Start Odin 1.3
4. Put the pit file in PIT
5. Tick repartition
6. Put PDA.tar it into PDA
7. Put phone in Download Mode (vol-down+home+pwr)
8. Connect through USB to your computer (make sure Kies is off)
9. Hit Start
10. Sit back and relax while your phone gets resurrected
Download the Rom HERE
Yeah try the kies method first. It might just work. If that updates the phone to Gingerbread, than we are good to go. Just follow the instructions on the ICS thread at that point.

[Q] Updated ROM Philz JB 4.1.2 XXLT6 via Odin but won't go past samsung gt-n7000

Hope you guys can help me.
Was updating my ICS (Criskelorom) to JB 4.1.2 XXLT6 ROM of Philz (PhilZ-cwm6-XXLT6-XSA-5.06.1.tar.md5) via Odin 3.07. Initially had some issues but, managed to get to where Odin resulted in a PASS. On REBOOT I only get up to the Samsung Galaxy GT-N7000 screen with a yellow ! triangle at the bottom. I was able to get to both Recovery and Download modes but would never get passed to homescreen and just stay on black screen.
Did it several times and got worried I'd brick my phone so I ran the ICS zip I had stored on my SD via Recovery mode and was able to get my phone running. Still want to pursue my JB upgrade though but, not sure if I was doing it right. Any help would be much appreciated guys.
Here is what I did...
MADE SURE OF THE FF.:
1) Install USB driver for Samsung Galaxy Note to transfer files between the phone and the computer using download of KIES from Samsung site
2) Enable USB Debugging Mode on the phone to connect the Android device with the computer
3) created a back-up of my contacts only
4) charged to above 80% battery charge
5) The phone should be factory unlocked and not locked to any particular carrier - I had unlocked it during my ICS upgrade from the GB original OS
THEN FOLLOWED THE STEPS:
Step-1: Download PhilZ-cwm6-XXLT6-XSA-5.06.1.tar.md5 for Samsung Galaxy Note to the computer
Step-2: Download Odin 3.07 which will help to install the root package on the phone. Extract the Odin zip to get Odin3 v3.07.exe file with some other files
Step-3: Place the Galaxy Note into Download Mode by pressing and holding Volume Down, Home and Power buttons together until a construction Android robot appears on the phone's screen. Now press the Volume Up button to continue to enter into Download Mode
Step-4: Run Odin3 v3.07.exe as an Administrator
Step-5: Connect the Note to the computer using USB cable while it is in the Download Mode. Wait for some time until Odin detects the phone. When the device is connected successfully, the ID: COM box in Odin will turn yellow with the COM port number. Also, the successful connection will be indicated by a message saying Added in Odin.
Note: If the Added message does not come then try another US port, try the one located at the back side of the computer. If Odin still fails to detect the device then re-install USB driver
Step-6: In Odin, click the PDA button and select the PhilZ-cwm6-XXLT6-XSA-5.06.1.tar.md5 file
Step-7: Now configure the Odin settings. Ensure that the Auto Reboot and F.Reset Time checkboxes are selected in Odin. As for the Re-Partition, uncheck the option
Step-8: Once everything is set, click the Start button in Odin. The installation should begin now and would take about few minutes to complete
Step-9: When the installation process is completed the phone will restart automatically. And soon a PASS message with green background will appear in the Odin indicating successful installation. After the home screen appears on the phone, unplug the USB cable from the device to disconnect it from the computer
Was able to reach Step-9 but my phone would not get to home screen.
Please help me with any advise anyone can give me?
thanks.
By the way, saw another option for Steps 5-6:
Step-5: Connect your Note N7000 with your PC using a data cable. Once the device is successfully connected, you will see a notification in Odin in the bottom left saying Added!! - if for some reason, you do not see the said notification, try another USB port. Also, check for ID:COM port being depicted by a number in yellow to make sure that you have successfully added your device.
Select the following files in Odin at their respective tabs from extracted XXLT6 firmware folder:
Step-6:
Click the PDA button to select the .tar file extracted earlier.
Click the Phone button, and select file with *modem* in its name (ignore, if this file does not file exist).
Next, click the CSC button, and select file with *csc* in its name (ignore, if this file does not file exist).
Click the PIT button to select the .pit file. (ignore, if this file does not file exist).
Ensure that Auto Reboot and F. Reset Time are the only options selected in Odin window. Also ensure to select Re-Partition checkbox only if you are using a .pit file.
Except since I only had the TAR file I ignored the rest so I assumed I was doing it right up to that point. Also, the YELLOW highlight in Odin 3.07, wasn't yellow but kind of light blue.
That was it. All I did. Still, not succesful.
Please help.
Thanks.
Phew! That's a lot to read.. The file you are trying to flash is just a kernel not a whole rom. That's why your phone after the flash has a JB kernel and ICS rom. That's why the phone does not boot. To upgrade to JB, download a stock rom from sammobile.com and flash it using Odin the same way just in PDA of Odin.

Sorry about the read. =)
Was thinking I'd rather be complete than have anyone helping need to ask more clarifications to help me. =D
Oh that's why. Thanks for the reply. I will do that.
So I need to get the WHOLE ROM from the site you mentioned. A ROM that is complete, Kernel and all. Actually I thought I did get a complete ROM. Did not realize it was just a Kernel. What would be the best way to determine if a ROM is complete? What is usually the size of the file itself? The one I downloaded was like 8MB so I thought that was pretty big. Kinda looked for awhile for that XXLT6 original JB ROM so didn't stop to think if it was just a Kernel. My bad.
By the way, are the ROMs on Sammobile rooted? Or do I need to root them?
thanks again!

They are just stock roms, to root again use the philz kernel but for jb this time. Also use the .zip this time instead of tar file, you can flash the zip file from stock recovery itself. You can raed more in philz kernel thread

Got it, thank you Sirs you've all been a very big help. I ran into some issues with TW right after completing the install of 4.1.2. Every darn thing was stopping even acore and TW. Was about to chicken out and go back to my safety ICS ROM when I got to read some stuff about needing to Clear/Reset on Recovery mode after any firmware flashing as well as Clearing the Cache so I did. And voila, it worked. I think I'll rest my worrying brain for now on the root. =P
I'll root it next week. I'll just have fun with it for now. Been up playing around with this for over 24hours now. Having too much fun but already drained.
Thank you again for you help!
same situation here...!!!
hello XDA ppl...
I had ICS 4.0.4 and attempted to use PhilZ-cwm6-XXLTA-ATL-5.15.0.tar.md5.
That took me to the same situation I think... kernel for JB and ICS ROM...
I power on my phone and it gets to a GT-N7000 Note + Yellow Triangle screen and NO MORE!
I can get to PhilZ Recovery Mode or ODIN Download Mode.
That´s all...
I will attempt right now what you told the creator of this thread and update if it helped.
any help is welcome...
FIXED!!!
AWESOME!!!
My bot is back again!!!

Safest way to get to JB with wipe (that is formatting) is to get philz kernel for ICS and then reboot to recovery do factory reset and wipe /system /data /internal storage /cache and then reboot to download mode and flash JB from odin. Else if you dont want to loose data, just boot into download mode and flash JB using odin.
