Restarting problem - Galaxy S I9000 Q&A, Help & Troubleshooting

Hello,my Samsung galaxy s is restarting constantly it started today after my phone frozen and I took out the battery after it booted it just showed Samsung logo and then goes to devil kernel logo after that just stays there and wont boot up and then restarts.I tried getting into recovery mode but it doesn't want to,only download mode works but phone doesn't get recognized by PC so cant do anything.
EDIT
When I charge the phone battery icon isn't showing like its charging it just shows empty battery and spinning indicator is frozen.

Seems like you have overclocked your phone too much or undervolted too much. What you need to do is go to cwm recovery and install a different kernel and see if it works.

Not yet going to try that later today.

To flash a kernel put your galaxy into download mode, connect via cable to pc, start odin, select in PDA a *.tar file and flash!
here you can download semaphore kernel for ICS Roms:

good luck!

Odin fixed the restarting problem,but now when i get in recovery mode its giving unknown volume and cant mount sd card error so is there anyway to install rom via odin?

LOL man just go find a firmware on sammobile.com (find JVK one) download it, put the phone into download mode, connect to odin. Put the biggest file thats in the firmware zip as PDA, CSC in csc ect. Tick "repatriation" "f reset time" and flash it. Then root it via CF-Root. (Find it on XDA - i hope you're able to do that) then itll all be good

I can only enter Recovery mode

Hi,
I installed a bootloader with Odin And after that I needed to Install a GBOOT with Odin but I can't enter dowload mode I only can enter Recovery mode. What do I need to do ?
I used this http://forum.xda-developers.com/showthread.php?t=1117990
What phone do you have?
What recovery version are you running?
How do you get into recovery?
A tad more info would be useful please.
9. Whatever I flash, I end up in Recovery! What should I do?
Flash stock Vibrant bootloaders, then ODIN to stock JFD. You should be good to go here onwards... I only had this issue when I tried changing bootloaders over MIUI/CM7. Couldn't replicate on Samsung ROMs... (AS QUOTED ON THE LINK PAGE)
Thank you for your responds
The recovery mode I run is CWM v 5.0.2.7 .
The thing is Odin can't recognize my phone because I can't enter Downloading mode so I can't flash that.
Hope you can help me further
if you got any rom's stored on your sdcard you could try to flash that and then try to enter download mode, otherwise you could go to "mounts and storage" and mount usb storage there and move over an rom to flash.
Try to flash phone via cwm. Now we have jvz deodexed version on forum. Maybe after it will be ob.

I've tried to flash a rom from my SD card.
@Emek can you explain it more clearly. I don't understand it.
Grtz William !
There is a rom on here you can flash using CWM. On the forum is a JVZ that you can flash without using ODIn, slap that on your sd card, goto recovery and install from sd and hopefully that should fix it
Sorry of being such a noob. What's a JVZ and which one do I need to flash.
Grtz William
I flashed this one Click
And It still doesn't work...
edit: Tried this one as well Click
It still doesn't work. I hope my phone isn't Bricked. Is he ?
They wont work as you need the correct gingerbread bootloaders installed first.
You ned to make or buy a jig then you can get the phone to access download mode again, and then using ODIN 1.83 reflash everything inlcuding the bootloader.
Jig instructions http://forum.xda-developers.com/showthread.php?t=819551
Failing that, see if you can buy a jig from ebay
Ok thank you. I ordered yesterday a JIG from ebay.
What do I need to do then. What do I need to flash exactly ... I don't want to screw it up another time. I liked the MIUI rom but he didn't recognize the external SD so that's the reason why I flashed other bootloaders.
So I would like to have MIUI with working SD card.
If the SD card doesn't work I won't to flash the original Android.
Grtz William
I would download and flash this for starters, it contains a bootloader as well make sure you click the bootloader section in ODIN.
http://forum.xda-developers.com/showthread.php?t=1380402
Then you can flash a custom rom afterwards, but dont change the bootloader once it works!

I bought a JIG so I can get into download mode right now so then I flashed the ROM that Buttwad proposed. But ODIN said the proces of flashing failed and no when I connect my phone to my pc my pc even don't recognize my phone so I can't put anything on my phone. What do I need to do. I am desperate.
u can acces the phone sd in recovery..
Am I blind or have you actually FLASHED a Vibrant bootloader over Galaxy S??
Seems like you have issues with key combinations. Try using the Volume down with power button and see if it could get you to the download mode.
Also, if your device is being detected by the phone, use "adb reboot download" to reboot the phone into download mode.
Here is the situation: I had the MIUI rom on my phone but my phone didn't find my external SD. So i searched a bit on the internet and I found a guy who had the same problem and he said that I needed to flash the Vibrant bootloaders so I did that. But then everytime I started up my phone I came in Recovery mode. I couldn't even acces downoading mode anymore. So first I tried to flash two other roms(This one And this onebut the problem stayed the same. So I bought a JIG and then I tried to put this bootloaderon my phone but Odin said ERROR after a while. So then I tried to flash this one.
But now I can't even enter recovery mode. When I start up my phone I see a pictogram with my phone and the pc with the sign that I can't connect them.
And my computer also don't find my phone anymore so I can't flash anything anymore.
Please Help !
I will give 8 euros to the person who can tell me step by step(easy) what I need to do to make my phone working.

2. Flash was confirmed rebooted.
3. Got Bootloop (Rocket Logo)
4. Could boot into download mode but PC not seeing device.
5. Removed battery for over 1 min.

I had the same problem today, but it worked when i did this:
- Volume down + Home + Power
- Do not press continue yet
- Open Odin
- Connect it to the computer
- Choose Continue on the Note
Now the computer should install two new drivers (modem and another one), and then the phone will pop up on the computer.
Odin is seeing :- 0:[COM4]
Thanks so much really thought I'd bricked it. Forgot all about Odin A Beer and a thanks to you both.
Just a note, not sure what went wrong but I had to flash a full stock ROM including the Modem, Code and Multi to get it working again.

Probably get a usb jig. Take your battery off.. Insert battery and connect jig. Your phone will boot into download mode. Then remove jig and connect your data cable and flash any stock Rom via odin

Go to this site http://www.sammobile.com/firmware/?page=3 and you will find Odin 1.85. Firmware for your country/region and flashguide. Register first, it`s free
It`s not so hard: download Odin 1.85, download the right firmware.
Put the firmware in PDA in Odin, close Kies and kies trayagent and PDLR in your windows toolbar (rightclick and go to taskmanager), put your phone in downloadmode, connect with computer and when you see ADDED in the left corner window of Odin and the the ID.com left upper window turns yellow press start and flash and let it boot.

have did some battery pull for 5-10mins, use different pc, different usb cable... also no use.
Does that means i need to pay samsung to restore back for me?

Not specific, you select any different, n as balok said connect directly to usb port, n close if antivirus running. Better download rom without antivirus, some time antivirus can cause problem, if any component of rom falsely consider as trojan.

I've gotten this before. I think it's caused by a failed flash in a rom, either interrupted or something else. The way I solved this was to pluck out the battery, put it back in, boot into download mode (power+home+vol down buttons). Then make sure u have Samsung usb driver installed and then run Odin as administrator. Continue to flash the stock firmware.

Also, the exclamation mark (!) between the computer and phone icons do not symbolise unable to connect to pc. It means something like "the phone needs to be connected to the computer to flash another firmware."

Bro, Don't worryYou can have it working. The exact scenario happened with me too. It happens when you enter in download mode & then due to some reason, you try to switch it on normally. In such case, it won't open either normally or in recovery, but only in Download Mode. So, remove battery, insert it again & press the Download Mode combo keys to enter download mode (Download mode works in such cases) & follow these guidelines:-
1. If odin is crashing, try another pc.
2. If odin is not recognizing your device even when correct drivers are installed, Then check the name of OPS file. For MINI it should be "Tass_v1.0.ops" (without quotes). Note that, device model number appears in Odin's Title Bar.
3. After that If Odin is hanging in btw (for ex: in setup connection), try another USB port.
5. If still problem persists, try another stock firmware.
6. If firmware update is successful and phone bootloops, remove battery, go to stock recovery mode & wipe data/factory reset. Then, wipe cache.
If you implement these correctly, it's 100% gauranteed that your phone should be normal.
Your problem should be solved by then.

Hi,

i wanted to set up a custom rom i restarted and reset and deleted the cash then installed the rom.
i think it was Retribution beta
then i wanted to update to that custom rom (MindCR ICS)
all i did i restarted my phone of course went into R mode and reset and deleted the cash then installed that next custom rom .
after installing completed when i rebooted it only gave me (samsung galaxy ace s5830i) logo and doesn't open the system when i restart it doesn't go into recovery or download mode it only gives me again the same logo.
even when i press long power button it shuts down and opens automatically.
is there any help knowing that i have already taken a copy of my system.

I have this problem before and i managed to use ODIN3 v1.83 (can use Odin3 v3.07) to detect my phone and flash a stock rom onto the device. I followed the advice given on this excellent thread by Supermini.
http://forum.xda-developers.com/showthread.php?t=1071970
As mentioned on his thread make sure you have the latest stock firmware from the sammobile site or by using Check Fus Downloader as per the guide in Rafael thread http://forum.xda-developers.com/showthread.php?t=1551156, a working samsung USB driver to detect your mobile on your PC and a copy of ODIN3 v1.83 (or v1.84, v1.87, v3.07 run ODIN in administrator mode if using in windows). Ultimately if this this fails you could always try a USB jig which can be purchased from ebay, etc. to get the phone into download mode.
Good luck and if this helps make sure you send a thank you to Supermini.

So . . . last thing to rescue your phone is buy on e-bay or in other place JIG if it isn't help you then try in phone service and say you tried install new ROM with Kies and your phone is brick (maybe it'll work).
Say to Service Centre Representatives that you kept your at charging last night
And when you woke up
It was not booting up
Pretend as if you dunno anything about root or ROM
They fixed my bricked phone
I am not sure if I am breaking any forum rule by telling this
Hey bro sorry for the late reply also, please before you do anything else try following my instructions.
1) download Odin v3.07
2) source the stock firmware you want to flash from sammobile.
3) make sure you have the Samsung mobile driver.
4) open and run Odin as administrator and load the single file in the PDA and highlight the tick box.
5) shut the phone down and take out your Sim card.
6) put the mobile into download mode as normal (press both up/down vol keys +power)
7) connect the phone to the PC and check in Odin to make sure its com port is detected.
8) then flash through Odin as normal.
I understand what your saying about no download screen appearing, I have found through experience that custom kernels can cause no download screen to appear. Normally with stock kernel this is not a problem but with custom kernels sometimes all you get is a black screen. Ignore this and just make sure that Odin is detecting the phone and try to flash, chances are it will flash the stock ROM and kernel. If you get the setup connection error in Odin and the fail 0\1 just try another USB port on your PC and keep persevering.
Please keep us updated so we can help you if you need it.

Why will it be hardbricked if the custom roms are based on s5830i stock roms?
But it is probable that we did I not flash the rom properly as per procedure..so is there a chance that it be bricked? Else the rom may have some problem... just telling the probability
