[Q] Random Boot Loop on SGS I9000 - Galaxy S I9000 Q&A, Help & Troubleshooting

hey guys:
I have a problem that's killing me. Everything was fine on my phone, i had flashed to Darkys v9.2 had the speed mod kernel and the lagfixes working great until randomly my sms kept force closing and wouldnt load. I tried re-booting my phone and now its stuck in a bootloop. I tried flasing back to I9000UGJH2 with Odin and when i do it flashes fine and stops at the recovery mode first boot with the following message:
format_vfat_device -> argv[1] : -F
format_vfat_device -> argv[2] : 32
format_vfat_device -> argv[3] : -0
format_vfat_device -> argv[4] : android
format_vfat_device -> argv[5] : /dev/block/mmcb1
k0p1
run_program: child excited with status 1
E:Can't mount /dev/block/mmcblk0p1
(No such file or directory)
E:copy_dbdata_media:Can't mount SDCARD:
copy default media content failed
After that i hit reboot system and it goes to the SGS boot animation and then to a black screen. My touch screen buttons(taking about the home and back) still light up when i touch them but its just a black screen. I can get to recovery and download mode but cant seem to fix the problem. If i boot to recovery mode it gives me the same message.
So i said screw it and tried to flash to I9000XXJPY. This worked but after it flashed it tried to boot but got stuck in a boot loop. I can still get into download mode but not recovery mode. So right now I'm stuck between a blank screen and a bootloop. If anyone has seen this and has any type of solution it would be much appreciated. Im in Canada and through sasktel. I really need my phone and im willing to try anything. im pretty computer literate. To me it sounds like there may be a problem with my internal SD card, but im not a doctor. Im fairly new to the SGS and i really like it. I've searched the forums and cant find a similar problem out there. I may have missed it, If there is allready something out there please let me know.
Edit 1:
Is it possible that there is a problem with my motherboard?

JH2 is 2.1 & Darkys 9.2 is based on 2.2.1
Whenever I have had problems with any ROM including boot-loop I always flash JPU (2.2.1) via ODIN with re-partition checked regardless of having any lagfig disabled or enabled.
Or you could try Darkys Resurrection ROM http://forum.xda-developers.com/showthread.php?t=940671

i tried that but no dice. i re-partitioned and flashed back to JPU but no dice. its still stuck in a boot loop. Does anyone know where i can get the original BMC 2.1 firmware or if that would help at all?

Help
Please someone help! Im still stuck in the boot loop. Im pretty sure that i've got a redundancy but not sure how to get rid of it. I've flashed all over the place and done a re-partition with the PDA, CSC, and the 512 pit file for JL2. Im still stuck in a boot loop and i really need my phone. Anyone have any other ideas?

I'm having the same problem, i tried to instal gingerbread on my phone but failed so i went back to froyo, when i finished rooting froyo it rebooted and i can see the S logo flashing and then the screen goes black and the phone just vibrates every 15sec or so. If anyone can help just tell me what to do. Thanks.

im having the same problem with my sgs and i found this while i was looking into the forums. some guy seemed to have the same problem and some how he managed to fixed it. this is his post and im quoting:
""Originally Posted by Encrypted1024
WOW! I am back up and running. This appears to be a data partition issue.
Can't say exactly what I did but here it goes. I may have done these things more than once today so you may have to run through this procedure a couple of times.
- Flashed JH2 with repartition and pit 512. (Stuck in bootloop)
- Flashed JL2 with Repartition and pit 512. (Boot to S Screen now)
- Flashed with SpeedMod 12
- Boot to recovery mode
- Format every partition
- Flash to JH2 with repartion and 512 pit. (Back to boot loop)
**** Heres where it was different***
- Flash to JL2 without repartion or pit
Booted up and working.
I know, sounds sketchy, but I must have reflashed my phone with 10 different firmwares today.
After I got it booted up I flashed it with Darky's 7.6 ROM. It gave an error at first about the data parittion but it repaired itself after running lagfix and changing to ext partition.
I may recomend to flash with Darky 7.6 and apply lagfix to rebuild the partitions and see if it fixes this issue right away.""
im not that into these kinda stuff i just want my phone working again. u guyz give it a try and if u succeed using this plz plz plz lemme no how u did it. or if u did it with a different method or something plz lemme no. thanks

Possible Eureeka!
I think i may have had an apiffany. The bootloop, from what i understand, is caused by a redundancy in the boot sector. I think what you may have done is by flashing the new speedmod kernel and formatting the partitions you may have eliminated the redundancy. That's what i think may have happened. If I'm wrong please correct me. I'm fairly new to this but I've done a ton of reading and research. If I'm wrong please let me know so that i can try and figure out what worked. I'm running into another problem now. I think i may have re-partitioned one to many time. Does anyone know a way to re-format the internal SD without being able to get into recovery mode. Ive lost that ability now. Its completly stuck in a bootloop no matter what i flash to.

bootloader
i think another problem that may be causing this mess is that on a couple of flashes i had the update bootloader and the phone efs clear checked. Is there any way that that has an effect on my phone? if so is there a fix attached to it? Please help, losing hope fast.

[Q] Semi-Dead Tab... please help:)

Alright, not too clued up, so probably should not have tried half of what I did!!!
Essentially in trying to change from Spacemooses Honeycomb Rom back to the Stock 2.3.3 (with all sorts of attempts in between an no progress), it won't go past the Samsung logo screen. Also read that a cause for this may be that I have not wiped the caches and data etc in recovery, but nothing in recovery seems to work, mounts failed, wipes failed... everything the recovery attempts is a fail! Now in trying to fix this I loaded another rom, the stock I800 Verizon I think... that starts up (nice sound), then flashes really dodgey looking lines all over, then just black and in that state only download mode was functioning, couldnt get into recovery!
So, as it stands nw, 2.3.3, stuck on samsung logo, recovery opens, but nothing works... not sure if its an ext4 or root related problem... those are just guesses though...
Help would be wonderful, I rely on this thing for varsity!!!
Thank you in advance!
Reflash stock Froyo rom, then go up to Gingerbread from there... You will probably loose all data when you restock. Hopefully you have a copy of your original rom..... Otherwise use another stock rom.

[Q] Revert from ext4 back to rfs...?

Alright, in trying to change back from Spacemooses honeycomb port to froyo/gingerbread my tab is now stuck... when I flash the stock verizon, it wont go into recovery and just flashes scary looking lines everywhere, when I flash a 2.3.3 stock Gingerbread it goes into recovery but recovery cant do ANYTHING... fail to mount, fail to format, fail to wipe etc etc etc, with every action (even the auto ones) resulting in a red error message! If left to boot, it simply stays stuck on the samsung flashing logo!!! Obviously it seems to still manage to get into download mode each time so I have hope, but it cant do anything else!
So further research and it would seem to me that I must revert back to rfs from ext4 before attempting these roms again, if someone can tell me if this is right... or just how to do it I will try anyway... been stuck for over a week an will try anything... please help Really need to get this working asap!

[Q] Need some Help, possible file system issue

I have a Verizon Galaxy tablet 7 inch the original one. I have had many custom roms on it in the past. Recently I had AOKP on it...I am not sure what build. For some reason my kids were playing with it and it would not boot up. I went into recovery and tried flashing AOKP and it would stay locked up on the boot screen. I eventually tried flashing all ICS roms with no success. I eventually ended up trying to go back to stock. I can get into download mode with and communicate with Heimdall and/or Odin. The problem is that every thing I flash goes into a boot loop. when I go into recovery I get an unable to mount error like E: unable to mount cache and one for kernel and about 6 more. I figure that there is something wrong with the file system so I have used a pit file when I flashed with no success. I am not sure if there is an issue with the file system being the wrong type or if I have to many partitions now. I know that the mount error in recovery is where the problem has to be. If someone could please point me in the right direction. I have been all over these forums.
Thanks,
Leroy
In order to determine if it is file related. Try to do a full wipe right after the Odin.
That is all 3 Wipes (Cache,Dalvik,Data)
Also check all the boxes on the right side of the Odin screen to flash the stock rom.
Well I got a little further now it boots up after 5 minutes and states encryption unsuccessful and asks to reset tablet. There is some threads on this so I will get to trying to resolve this. In fact I just realized this is how everything started off I didn't read the message and powered it down. So it must have started on its own or from the kids playing on the tablet.
Is there any way to determine if your internal memory is shot. It seems like there is a problem mounting my internal memory > emmc?

[Q] Boot Loop / Can't Install ROM - Advice Required

Hi,
Recently, my wife's phone started to boot loop, would eventually boot into Android but couldn't install apps etc. Anyway, tried to reset to factory and at startup, went into recovery mode with messages such as
E:failed to mount /dbdata (Invalid argument)
Can't access to '/system/csc/XEE/system/'
Doing a factory reset from recovery screen gives rfs format errors.
Anyway, next logical step in my mind was to try to install a ROM and pit file that I downloaded in case partition table was corrupted.
So to do this I used Odin / JVH_JV3_JPO.tar ROM / s1_odin_20100512.pit file. This seemed to install fine but unfortunately went to recovery screen again after rebooting so no joy.
Looks to me like onboard SD is damaged - thoughts?
I have a 16GB micro SD card in the phone also and would like to be able to use that to boot from. How can I do this? Bear in mind that the only 3 screens I can get to now are Recovery Mode / Download Mode / Boot loop.
A similar scenario appears to be discussed here but some of the posts on that thread imply that the process has problems, there are broken links in the post etc.
So I suppose, what I want to know is - is my internal SD damaged? And what's the best approach I can take now?
Thanks,
Julian.

[Q] Stuck at Samsung Logo... Repartition phone?

So, to make a long story, short, for the past couple of days my phone has been soft-bricked... It first happened when I attempted to flash dmodv6 in CWM. Everything looked good throughout the installation, however, when I rebooted my device, I got stuck in a boot loop where It would say "Samsung Galaxy S III GT-I8190" for a few seconds, the screen would go black, then say the same thing again... over and over and over...
After a lot of trial and error because of NOT making a nandroid backup via CWM (stupid, I know - I had made one via Titanium Backup and thought that might be good enough), I finally was able to boot. Thanks to xXPR0T0TYPEXx, I was able to flash another rom by puting my external sd card into another phone, loading another rom onto it, and putting it back in my phone. I now had Cyanogenmod10 and was able to boot back up.
I attempted to restore the Titanium Backup I had made with this new rom (stupid again, I know) and it made almost every service on the phone stop working... I desperately wanted just to get back to square one - to install stock firmware and go from there. I followed tys0n's guide on flashing stock recovery then attempted to install stock firmware... All seemingly went well - I booted up, got past the initial "Samsung Galaxy S III GT-I8190" logo and finally got hung up at the "Samsung" logo. I left it one while I went to sleep, just to see if it would eventually work... I woke up and it was still the same. I tried flashing different version of the same stock firmware but it all ended in getting hung up at the "Samsung" logo.
A major problem is that I absolutely CANNOT flash a custom recovery via Odin - it just will NOT work. Everything looks good on Odin's end - I PASS, get the (succeed 1 / failed 0) thing but am sent to stock recovery every time I do the 3 button combination. I've tried many version of CWM and TWRP.... NOTHING. I've even unticked the "Auto-Reboot" button in Odin and pulled the usb cable and battery upon completion but, but nothing ever works. The only way I was ever able to get CWM on my phone in the first place was by an in-phone app... Rom Manager, maybe? I can't remember. But, as it is, that method is out of the question.
I've learned a lot about what I did wrong so that's the only good part of all of this. Now, all that's left is to fix the thing so I can go about it right. I'm completely out of ideas, have spent almost a full 24 hours searching solutions to this problem and I am at wits end...
I just want to get back to stock firmware... Any ideas, guys? Should I go about re-partitioning my device at this time?
I have the PIT file... but I'm not sure as to which firmware to choose. I imagine a firmware that is 4.1.1 like my phone was... but I'm not sure about the region. I live in the US and there is no US or North American region firmware version.Can anyone shed some light on which one I should choose?
My SSN underneath my battery say "GTI8190GSMH".
I'm sorry this is so long, I just wanted to explain what happened as best as I could. So, should I go about re-partitioning my device at this point? If so, what firmware would you recommend for my model? Are different region versions okay for a this method?
Or is there another way?
Thanks, guys. :silly:
Some additional details (if it will help): I can, indeed, boot into both recovery and download mode. I just can't seem to flash a stock rom that will boot past the "Samsung" logo.
I've even attempted to flash the param file after the rom flash but it didn't help.

Do you have the stock recovery now instead CWM? If yes do (if you didn't try it) a factory/data reset and wipe cache but it will delete your pics, music etc on your internal storage too.

Yeah, I have stock recovery now and I have tried that many, many times... Even if I install something like CyanogenMod, it still gets hung up on the CyanogenMod boot screen... And if I boot a stock firmware, it gets hung up at the same place at the "Samsung" logo...
I have an idea that one of the only options left is a PIT re-partitioning... If so, how would I properly go about that? Load the PIT file and the stock firmware in odin? Or only the PIT as PDA? I've heard a couple of different things and am unsure.

I don't know about PIT files but some people got this message : "CUSTOM PIT BINARY" in recovery mode after flashed a PIT file (maybe they used a other PIT file that wasn't compatible). So make sure you use a PIT file that is GT-i8190 compatible.
I tried flashing the PIT file for the hell of it because I am completely out of ideas.... It failed repeatedly in Odin.
I have no clue on how to fix this... I've tried countless roms and they all get stuck on their respective boot screens. The only one that gave me a glimmer of hope was Cyanogenmod10.2.... It went as far as saying "Android is upgrading" and showed "starting apps" but it got hung up there.
I don't know what to do, guys. Someone help!!!

Use a custom ROM to see if it will fix the problem .Try to flash CyanogenMod 10.2 by NovaFusion via odin or if you flash CyanogenMod 11 then you will automatically get the TWRP recovery. NovaFusion Team Homepage : novafusion.pl. I know you want the stock ROM but try other ROMs to get a booting phone again

I have... I've tried numerous stock roms and numerous custom roms... all versions of Cyanogenmod, Chameleon, Carbon, Slim mod, etc... They all get stuck at their respective logos.
I even tried the Cyanogenmod with TWRP but, as I explained earlier, I absolutely CAN NOT flash a custom recovery unless I use what ever app I used.... It doesn't work with Odin or with a rom. I don't know why.
I wish someone had more info on repartitioning my phone and if it would help.
