My phone can't see SIM card - Galaxy S I9000 Q&A, Help & Troubleshooting

Rooted today. Clean install, flashed Slim ICS 4.2 and semaphore 1.30s kernel. Booted up and I have no signal, tried different radio and same story. Is it broken? Bricked?

Try different version of Semaphore kernel. Semaphore 2.0.6 is out. It is definitely not bricked...If problem exist go back to JVU through Odin and flash the rom again....

when flashing some JB roms imei getting lost, try backing up the efs folder or if you have it backed up restore it with root explorer or other similar app.

Did you wipe the cache partition? That was my problem when this happened to me as cyanogenmod uses a different cache partition.
If you still can't get it work, try mounting the internal SD card to MTP and flashing a different ROM, if not, you'll have to restore a stock image with Odin and start from the beginning.

Help, phone only booting to recovery

Hi I was running Helly Bean and I was experiencing some lag that i couldnt fix so i decided it was time to start fresh (phone was getting to be a mess anyways) so i formatted my phone and one-click to a stock rom. (rogers i896 2.3.3 with bootloader). I used heimdell to flash kernel with recovery, then flashed devil kernel, reboot recovery, then flashed helly bean as per thread instruction and my phone kept booting into recovery only. So i tried to start over 2 more times with the same results, I even tried to flash CM9 stable release and it yielded the same results.
Can anyone shed some light as to what i messed up? My only option now is to use stock app since i cant seem to get anything else to work...(pleas dont make me go back to touchwiz)
Any help is appreciated,
Thanks.
PS phone works fine on stock rom
This happened to me once... I think it has to do with repartitioning and Devil kernel. If you flash devil first, it seems that something is telling the CM installer that the partitions are all good to go, even though it is clearly not the case. So use heimdall to flash the first kernel, and go straight to the ROM install, making sure to flash the ROM a second time after it reboots into the new recovery.

Thanks, works first time!!! Looks like im going to have IMEI problems but thats another battle lol
odin to stock 2.3.6, charge to 100%, then go to recovery, 4w, 2f, then install helly bean.
just went thru this last week.... accidentally flashed incorrect ROM to Captivate and phone started acting wiered.
Then came to know i have the wrong bootloaders and kernel. Just installed GB bootloaders and phone started booting to recovery.
then tried to flash ics rom and soft bricked my phone.
Used the "hold both volume buttons and plugin the USB cable to computer" to get into download. then ODIN to stock GB. then used KKroot and then flashed Slim ICS. Now the phone works great.

[Help/SOLVED] Flashed a Kernel & now cant access phone!

I was playing around with a few roms and kernels, I then got CoCore 6.8 and flashed it through CWM onto ParanoidAndroid and now I cant access my phone or go into recovery. When booting normally, android.phone Stops working and when booting into Recovery I just get a loading circle ( similar to the buffering circle on YouTube )
Thanks in advance.

Be more specific: flash from what rom and kernel?
You can read the thread about downgrading from JB to GB, it has all the details you need to start from scratch.

So I had the ParanoidAndroid 2.90 rom, then I flashed CoCore .8 using CMW onto it and now I cant accces either my phone or recovery.
Trying to go back to stock with Odin now.
PA is cyanogenmod based, and such ROMs only work with cyanogenmod based kernels. On other words, cocore is just for stock roms. You mix both of them and you'll end up with what you have right now...
Flash everything again with odin and you'll be fine!

Okay, I got the tock onto it but its stuck in Bootloop :/
Will I be able to just flash CWM and go back to a Backup without using odin to reinstall the stock ?
Okay, I managed to get CWM up and running, currently im restoring a Backup from this morning.
// Problem solved, restored perfectly and works now. Thanks for the help

[Q] Mackay ROM - going back to 3.4.6

Firstly, I must say that bought my i9000 with Mackay rom (4.1.2 then) on it, and that I was very satisfied with it. Since then, I've changed several roms on my SGS.
But, I've been using a new 4.0.1 Mackay KK rom, and still not completely satisfied with some missing options, so I wanted to go back to JB, but I came across some issues. I did exactly how the developer wrote, but no luck. I've been trying to install rom with twrp, but it fails. OK, the developer mentioned it could happen, so I tried to flash again, as said, but still no luck. After that, I tried to flash old kernel, the one for JB, but failed again. TWRP now won't flash anything. Just to mention, the phone isn't bricked. I can power it up, and it works fine.
How can i flash back to old kernel, so I could flash JB again? Or, there is some trick to flash back to JB with kernel 0.600?
Thank U in advance,
filipidis
EDIT: I succeeded in going back to JB. I was somehow able to flash cyancore kernel over TWRP. Then I flashed it again with Mackay kernel, and flashed JB 4.3.
Now, waiting for stable version of Mackay KK.

[HELP]No Wifi or Mobile Data After Stock Flash

I reflashed stock after a TWRP backup sent me into a bootloop and now my phone can't recognize the SIM or connect to Wifi. Can somebody please help?
Edit: I'm not sure why this worked, but I fixed this by trying to flash the Havoc custom ROM. The ROM wouldn't boot, but when I reflashed stock afterwards, the problem was fixed.
was your imei intact before you reflashed back to stock

I'm not sure if you're referring to when I reflashed stock and had problems or when I reflashed stock after trying to flash Havoc and fixed it. I can't answer either way because both times I reflashed I was stuck in a bootloop, so I couldn't check the IMEI.

Since everything works when you have the Android One ROM installed, try backing up the EFS with that ROM installed and restoring on the ROM you want to use.
No wifi after flashing ROM
I had the same thing happen after flashing a ROM. In my case, it was a repeatable error. I reflashed the modem partition from the stock modem after flashing the custom ROM and everything started working again.
