Same thing happened to me just like 30 minutes ago. I solved it by pulling the battery and pulling out my micro SD card and putting it into a SD card converter (or whatever you want to call it..) and then I put it into my computer deleted the update that I was trying to put on my phone replaced it with a rom that i knew worked. turned on my phone while holding home key. Wiped the phone and reuploaded the older rom. It fixed my phone, but it ment no new cool rom for me.
I was trying to flash macdroid. Anyone know what I may have done wrong? I really like the look of this Rom and would like to try it out...

One place I have seen this happen is when you try to flash a donut ROM w/o wiping/reformating your ext partition. If there is any "old junk" in your ext partition you get the black screen. Also I believe your ext partition needs to be "primary" (along with your FAT32)
Try a clean reformated SD card.

this is the only way to make sure it's not the rom's problem

[Q] Freaky i9000M problems - any idea why/what/who???

Hey guys, I need some advice please. Have had a number of odd happenings with my i9000 in the last 24hrs and not sure if some of them are the fault of the phone, or my fault! Apologies up front too for the long post – didn’t know how to put it all more succinctly!
First things first – it’s a Galaxy i9000M Bell vibrant. Came as Éclair 2.1, upgraded recently via Kies to Froyo 2.2, Build UGKC1. Then rooted with SuperOneClick, successfully without drama. Can get into recovery and download modes no problem via 3-button method.
Bit of background info – int SD 16GB, inserted 16GB ext SD. Before any upgrade to the phone had some issues where some photos taken with camera on the phone would show up in gallery as a corrupted/damaged icon. Pretty sure this occurred on default int SD so changed save location to ext SD but same deal now and then. Formatted ext SD – still happened from time to time. Actually replaced ext SD (exchanged at shop with brand new one), but same thing happened again. Figured I’d learn to live with it as only happened now and then.
So, phone rooted last week. Had been doing reading on ROMs/kernels before trying to flash anything. Only root-type things I’d done were to get TiB (and do full backup), Root Explorer, Terminal Emulator and Wireless Tether. Y’day I noticed after taking a few pics that one of the ‘corrupt’ icons that had previously been in place of an older photo, was now in the spot of one of the pics I had just taken (and strangely, the older, apparently corrupted photo was now fine).
I tried to delete a few of the photos but the phone just got stuck trying to delete. Had to force close it with task manager. Same deal if I tried 1 or many photos. Did this a number of times but no joy. Eventually just took ext SD out, put it into PC and deleted them that way, then put back into phone. Now it took AGES to complete the media scan on ext SD – like 5-10 mins! This happened a couple of times if I tried to do anything with the SD eg. save a file to it. So reformatted the SD card (on PC) but same prob when put back in phone.
Figured it might finally be time to try a new kernel in hope it may fix this bug. Had speedmod all ready to go (but hadn't been brave enough yet to try my first flash) so flashed K13E-500Hz via Odin. It worked fine, but “media scanning” problem was still there. Figured I might as well go the whole hog so factory reset the phone via recovery 3e. Did this ok, and “media scanning” was no longer a prob when I put the ext SD card in, just took a couple of seconds – hooray!
Restored apps + system using TiB which also appeared at first to work fine. Put a few pics and ringtones on the ext SD and all seemed fine. Then some app icons disappeared from the Applications pages. They appeared ‘crossed out’ in TiB and when I went to restore them again the phone spazzed out saying (sorry can’t recall exact wording) there was not enough memory and to delete some things to try to fix this. A red SD-like icon appeared in the top bar. I tried rebooting the phone via recovery 3e and it went into a cycle of vibrating, flashing up the turn-on screen/display then shutting off, but vibrating occasionally and lighting the soft touch keys but nothing else. This did this for about 5 mins and in order to try to save battery/stop the whole process I ended up factory resetting yet again via recovery.
Today it works 'ok'. Have not braved putting an ext SD in yet! Got Tib off the market but have also not dared to try to restore any thing yet. Oddly, in TiB it shows “System ROM” as almost fully taken up ie. Full green bar (289MB, only 6.06MB free) – this can’t be right can it?
Internal, DB data and SD card all show as ~99% free.
Deleted Dalvik cache in case that was the RAM problem but it didn’t do anything much (freed up about 6MB only).
So, my questions!
1. is this all because of the ‘corrupt/damaged’ issues before I’d done anything to my phone?
1b) How do I find out what RAM is available and what is using it all up? RAM manager is showing 197MB/339MB used but is this what the 'memory' problem would be? Clearing memory doesn't seem to do anything.
2. I never installed any kind of lagfix (knowingly anyway) – could this be a reason - have seen lots of threads/posts about disabling lagfix before flashing roms or kernels
3. I thought factory reset would wipe everything – but it obviously kept the int SD info ok (I’d copied Tib backup to ext SD and also to dropbox just in case) –should I maybe reformat the int SD and factory reset again?
4. If the issue is the phone itself (with prior corrupt file problem) – would it be worth flashing back to stock kernel and unrooting phone to try to bring back and get fixed/replaced under warranty?
Thanks in advance for any help anyone can offer!!!!!!

Read your hole post its really long. Can't answer to all questions. But did you try to put your phone as massage storage to your pc and mark everything thats on int sd and just erease it. When turn your phone off, put it in download mode and flash a stock rom (with 3 files) from samfirmware.com with repartition enabled? Maybe that works. Good luck! Before i forgot ext 4 is the better filesystem. Rfs getting laggy after a while cause its not the correct filesystem for sgs. Thats why ext4 is the main format on sgs2.

hey thanks for the reply.
i know it was a super-long post, apologies again.
didn't try deleting the ext SD whilst connected via usb. got fed up with the phone not being able to delete & freezing when i tried that way so just took SD out and deleted them with card plugged directly into laptop.
as it happens, since 2nd factory reset, i've been cautious about what i do. no ext SD yet (though might try that tomorrow). didn't do full restore of missing apps and system files as i did the first time. so far have only restored about 6apps via TiB and wifi locations. Phone working ok...for now.
next steps:
1. try taking loads of photos to see if 'corrupt'-style icons occur again with int SD only;
2. maybe try an ext SD again after reformatting it and see how the media scanning goes and how it goes having music/vid/pic files on it etc;
3. gonna look more into the speedmod kernel ie. the tweaks which i think i need to access via recovery mode.
not quite ready to try and flash a custom rom with that little scare!
...but would like to try a custom rom at some point when i feel more educated about all this

Just look at the search function on xda or google. There enough guides about flashing. Know how you feel. The first time i flashing it was very scary for me. Got a heartbeat like a technosong. If you want i can write you a guide for every step. Trust me it is easier as it sounds. Just pm me and i will help you out.

[Q] phone keeps rebooting, if more than 50 apps on sdcard

hi guys, i start a new thread cos till now nobody could help me.
if i move/install more than (about) 50 apps on sdcard, my phone works only until shut it down.
once rebooted, it keeps rebooting (it seems to happen while scanning apps on sdcard).
only solution is, to put sdcard in pc and delete some (doesn´t matter which) .asec files from .android_secure folder.
this problem only appears in android versions higher than 2.34 and it seems to appear on other phones (not only lg) too.
please, please, does anybody has a solution or an explanation???

Which ROM are you using?
Anyway, just an idea, looks like a format problem in your card, have you tried to copy all the apps out of the card (v.g. to a PC) and reformat the card?. You can copy verything back afterwards.
Sometimes, it just happens the card is left in a funny state by an O.S. crash or by silly accidents (like pulling it out without unmonting it first).
Hope it helps.
Cheers.
NOTE: If you are copying things out, remember there might be some hidden directories in the card, set your file explorer to show them.
NOTE2: I remember having a similar problem with an old WinMo 6.5 phone, turned out my SD was a fake one not having the expected capacity.

formatting card doesn´t help.
i tried it with 4 different cards. formatted all. did fullwipe, after fullwipe, started with clear rom, installed all apps again. everytime the same: if the´re more than 50 files in android secure, phone keeps on rebooting.
at the moment i use cm9 kang3. but like i told it´s the same with every rom based on android higher than 2.34. so i tried it with miui, miui kangs, cm7, cm7kangs etc. eveytime same thing, cos they´re all based on android higher than 2.34.
these guys have the same problem:
http://forum.xda-developers.com/showthread.php?t=1446961
is there anyvody who have an android version higher than 2.34 and more than 50 apps on sdcard and phone doesn´t reboot???
don´t believe that.
so i think i go back to gb 2.34. but is there a rom/kernel with a ramhack, so i got 404mb free ram? and i need the cars mounted in c-style, so external sdcard is sdcard and internal is mounted as _internal..

I have more than , 230 apps, and 40% they are on sdcard.
And i dont have any problems with it.

hmmm... ok, strange. which rom do you use and how many files do you have in android_secure folder and how big is it?

[Q]Internal storage 75% full

Hi,
I am using latest JB FW, Timin8r rom. I was on stock kernel.
Last night i rebooted my phone and got the grey triangle. I left the phone over night and it was OK in the morning.
However, I got a message that internal storage was 75% full and a popup appeared asking me to transfer data to my ext card. However, all options said 1 file and 0% and the transfer button was greyed out so i pressed cancel
An hour ago I flashed the new stock kernel with recovery and thats when i noticed that my file structure had changed, Inow have
ext-card
sdcard
sdcard1
(Sdcard 1 is actually the ext-card)
However, from the sdcard (Internal storage) I have lost all the folders from Android to Notifications (Listed in alphabetical order). What is left is only a few MB but storage on the phone reports that there is 10Gb still in use. So I think the data is still there just not visible in root explorer or on the PC when I mount phone.
I am going to leave the phone alone whilst I am at work as it may need to settle, but has anyone else got any ideas?

Hay man, I have a similar issue, though not as bad, I rebooted and got the gray triangle, I waited and shows low storage. Curious why, I looked in explorer it showed the same storage folders you have.
Sdcard
Sdcard1
Ext-sdcard
Though the only problem is sdcard and ext-sdcard both show the contents of what my ext-sdcard actually shows which is strange. Seems to have duplicated itself in another folder...
I might try and delete one and see what happens.
As for your problem, you could try and flash a stock ICS to reset the file structure?
Sent from my LT30p using xda premium

The ext-card has not been dupicated its just two seperate paths to get to the same place.
My main concern is the missing folders in the sdcard (Internal) They still appear to be there as there is a discrepency of 10 gb between what is reported to being used and what I can actuall see.
These include my recovery backups and lots of photos so I dont want to format yet.
I have a copy of some backups on my pc at home so when i get home I can restore and check.

Same issue

[Q] Xperia Z does not read internal sotrage!

Hi. i have a xperia z from tmobile which i rooted and installed the dual boot recoverys!
I usually use the twrp recovery since the cwm doesnt work for me , i dont know why but thats not the problem.
It's a locked bootloader.
well i was flashing a zip file using the twrp and everytime i flash something i always wipe cache/dalvik since ive always had many rooted devices.
But when i did so on my xperia z, it was showing the loading bar like is was wipin, it took awhile then the lights of the display dimmed and turned off.
I thought it wouldnt turn on and i was puzzled...but i booted it up and it turned on fine.
however after that i tried to download a file off the broswer and it said "no sd card" and im like? ok?
i thought it was the actual sd card at first, ejected it put it back and it shows that it reads it..
then thats when i noticed it was talking about my sd card, but my internal storage.
it shoes the amount of storage im using but not how much i have in total which is strange..
it wont let me use certain apps saying its not reading it...
i tried using fixed permission but it does nothing to help and trying to re-wipe cache says error and doesnt read..
hope someone can help me, sorry for the long paragraph! lol
EDIT: BTW when i connect it to the pc it shows my both storage devices, internal and sd card but on the internal it says "0 bytes" and shows nothing. but on sd card is shows the gb amount correctly!
