After I failed at upgrading my phone to 2.3.4 GB I ended up just using Raver's KC1 cleanup with ODIN and put the SGS4G back to the custom UI Froyo. The phone started and I put the SIM card in and the phone cannot recieve any signal and also the phone vibrates randomly at times... Any help/suggestions? Please and thank you, reply or PM me please on how to fix my phone! Thanks!!!!
Thanks YOU!!! AGAIN!!!
Go into recovery, wipe the caches. Past that, maybe a factory data reset.

The phone is still the same. I did both before this problem too. Any other suggestion mate?
try reflashing the rom without your SD card in the phone. Then format your SD card before you put it back in the phone (back up your important data first).

If it's via ODIN (which I think it is) you should only need to put the 1 file in the PDA section. Don't mess with any of the check boxes.

Which one did you flash? Are you still having issues?
Remove your sd card and sim card.on your computer, format the sd card to fat32. Wipe everything and make sure you back up whatever you need. Set it aside. Odin the froyo bootloaders from the gb starter pack. If you are staying on froyo, then Odin krylons kb5. If you are going to gb, Odin the gb bootloaders. Once you Odin kb5/gb ROM (which can be done according to the gb start pack), factory reset, wipe both caches. Boot up and let sit for 10 min. Shut down, factory reset, wipe caches again and fix permissions

Okay so could you walk me through on how to do all this? I really want to get this fixed right. Also i found out the signal issues are from the phone not reading or tethering? the SIM card which is in place. Thank you for the help and please help me a bit more on how to format my sd card to fat32 and where to get the froyo bootloaders and roms and such.
Thank you so much
Search for the gb start pack thread. It has all of the files you need. Try following that and wiping the sd by plugging the as card directly into the computer and right clicking and going to format. If you have any specific questions, I'll be happy to explain but I'm not sure what elder you need help with. once you run through it, it makes sense. we'll fix this. Pm me if this thread gets lost in the fray

Hi, I have a serious problem with my phone. So here's the long story (sorry).
First I turned off my phone and turned it back on but it froze at the S logo and went on vibrating every once in a while.
I used odin to flash it but it restored it to eclair 2.1 and all my photos and music are gone. I was wondering if there is a way to restore the lost data.
Thanks.
Basically, no. Sorry.
My thoughts too. Unless u had them on ur external card the wipe erases them all.

Also, I was on android 2.2 prior to the flash but after, it's 2.1 with the AT&T start screen, is there a way to revert back to 2.2 rogers?

Only a master clear or formatting the internal storage would do that. A simple odin one click flash will not cause that.

And yet it happened...im quite upset. =/
The best and easiest way to flash a rom without having any bugs or flaws,etc.
follow this to a 'tee' and you will have no problems, guarantee you.
Instructions:
1. Download .rar from link and extract it
http://www.multiupload.com/FO6TA6OBAH
2. open odin
3. put pda into the pda, phone into phone (their all in the respective folders)
4. let it finish wiping your phone and everything
5. once your phone boots, back up everything on your internal sd
6. go into settings and do a factory reset then let the phone reboot
7. put the rom you want to flash onto your sd card
8. turn off the phone and go into download mode (both volume buttons then plug in your usb cord.) flash gtg's community kernel. (in the root folder, put that .tar into the pda section) let it finish converting the partions.
9. once it finishes and boots up do this:
turn off phone, then:
using three button method. (volume up, volume down, power button. once you see samsung label release power button and keep holding volume buttons til you see your touch buttons light up, thats the way i figured out when to release them)
10. once the red screen appears, do: wipe data/factory reset, wipe dalvik cache
11. install zip from sd card, choose the rom that you placed onto your sd card
good job. works for me!
Which version of flashing stock does this use? Gtg unbrick?

Haha, the best way is NEVER using ODIN. Heimdall is much much better.
And why would you return to stock before every flash?

A clean slate. I use to do this all the time with my Captivate. Never had any problems installing any rom. Still do it now with the Infuse, and no problems installing any rom or Hellraiser Hybrid rom.

Never did it with the Captivate, never do it with the Infuse, never had any problems. You have a clean slate every time you flash a ROM as long as you wipe all the data and cache partitions. The system partitions are already overwritten with the flash itself. Basically going back to stock is just doing the same thing twice. Unless you are having some big problems and want to drop back to all stock files to see if you can fix a problem, it's generally unnecessary and just a waste of time. I mean, it doesn't hurt if you want to, it's just redundant.
All you gotta do is flash your ROM from Heimdall or CWM, wipe your data and cache partitions, boot up and you're done. As clean and fresh of a slate as it gets.

some instructions say to wipe data factory reset wipe cache before installing custom ROM,
some say after install wipe data factory and all that...

I was once watching a youtube video on how to flash and he said something very simple, "wipe, fix, delete, get rid of, whatever. Old school rom flashing: make sure that you knock out everything so that you start on a fresh slate." Jordan is definitely right and knows much more than I. But I agree with AJerman that says its redundant. Just my two cents.
Jordan would you recommend using this method if you just got and rooted an infuse?
(have a warranty replacement on the way )

Using this method coming from Darky in an attempt to flash the FusionXII ROM, i recieved the message "installation aborted" after clockwork mod started and then ended the flash of the file. any advice? i cleared both data and dalvik in that order.

Odin back to Froyo, then Odin one of the gingerbread leaks, Odin entropys kernel, turn phone off and get into cwm and flash Fusion. Make sure to wipe data as well.

Alright, well thanks Big. I'm going to just send it into Samsung, and I wanted to delete all of the ROMS and modems and whatnot off of it beforehand. Probably won't really matter to be honest though.
If you have download mode, then you can just use the one-click I made. It's a Heimdall one-click in the development section. It should also be able to reload all the firmware on it.
I recently bought a charge off of ebay and it came in and I noticed it had an Gmail account still synced with it.
Ok I thought, I'll just remove it. I go to remove the account and it says that "some apps require this account to remove this account you need to reset phone to factory defaults".
Alright so I go to do that and the phone reboots after I wiped data/cache and I go to add my account and realize that the other account is STILL THERE. So I do the wipe a few more times and still stays there.
By this time I figured I would root the phone and install CWM and try and wipe data that way. That still didn't work and I just started trying to get a stock rom back installed and finally I did. Except the ACCOUNT WAS STILL THERE, but now I'm getting a ton of FC's ranging from google apps to other processes. I've tried to install different rom's/CWM's/kernels in ODIN on my Window's laptop and I would alwasy just get the talking voice saying things like "converting data partition" and then it would just boot back into the stock but keep force closing.
I am now using my Macbook Pro on spring break and am trying to fix this using Heimdall but i've still had no luck. Is there anyone that can help me with this?

Okay so it seems like you're sorta familiar with this kind of stuff so this shouldn't be too much trouble for you. You're going to need to go back to stock EP4D ROM and re-partition your device. Here is the link to where you can solve this problem: http://forum.xda-developers.com/showthread.php?t=1111486
You're going to have to use Odin (You're going to need Windows to run Odin) fit this because Heimdall just doesn't cut it and personally I've never used it. Get Odin 1.82, it works really well with the Charge. Download stock EP4D and also the charge.pit file from the posted link. Place stock EP4D md5 file in PDA in Odin and charge.pit in PIT. Make sure you have Re-Partition checked and Auto-Reboot and F.Reset Time UNCHECKED and press start. It will reconfigure everything and basically give you a brand new phone on the inside. Hope this helps and if you have any more questions just go back to the link to Imnuts' thread I posted.

No problem man I'm glad to help. If you want you can try a full data wipe. Boot into CWM and mount everything i.e. \system, \data, the whole nine yards and then wipe data/factory reset, and also wipe cache partitions and Dalvik cache. Then install whatever ROM you have available and see if that works. Otherwise you're SOL until you get a Windows computer and can Odin back to stock and re-partition everything.
EDIT: Just to clear something up, to mount everything scroll down to 'mounts and storage' in CWM.

even though i never got the same message, but even I cant see the rest of the memory..only 1.8 is present....
Hmmm... Could be a hardware issue then. As for your network, you have to set your phone on the correct APN. It takes forever for my pc to recognize my internal storage or that its connected, but I think that's an issue with some people on ics. Try reinstalling the samsung drivers.

For those who have been following this thread, the moral is this:
You're only bricked if you literally have a dead phone that doesn't respond at all. Can't turn on, doesn't vibrate, doesn't show signs of charging, doesn't go to DL mode, etc. Even then, if you have the unbrickable mod then you are literally never going to be able to brick your phone, even under circumstances that would normally cause a brick.
Well it bricks, but you run a program that takes advantage of the hardware being wired to be able to load things into the RAM while the phone is off and execute an upgrade from there!
