[Q] Installing ROM from external sd card Plzzz Help - Galaxy S I9000 Q&A, Help & Troubleshooting

Hi, I am seriously confused about this.There seem to be loads of threads but no proper description.I have a gti9000 with a corrupted but not dead internal memory.Hence I was looking for a knowledgeable person to please guide me on installing a rom from the external SD card (8GB).
The only partial solution is provided in this thread http://forum.xda-developers.com/showthread.php?t=1893354&page=2 but the link to the modified tar file is dead.Yes, I have partitioned my external sd into 6gb fat32 and 2gb ext4 and also tried 6gb fat32 and 2gb reiserfs.It seems as my internal
memory is not dead and only corrupted ,the issue remains.Please I am sure someone knows exactly what to do.Thanks for reading.Your reply is greatly appreciated.

Already tried to flash back a stock rom?
You could try to flash a Stock ROM. First, make sure you have installed all Samsung Galaxy S i9000 drivers on your computer, download Odin, CF-Root Kernel for Odin, PIT file and the stock rom files under .md5 ( CSC, PDA, PHONE) , after that enter in Odin, prepare the files there...( P.S: you can re-partition there ) , enter in Download Mode using the 3 button combination Home + Vol.Down + Power , Odin will detect your phone , click Start and wait.
You can find all files under "GB Flash KIT"
I had a similar problem and this method, solved it.
Hope it helps.

I have already tried this many times over .Also tried the recovery kit.The problem is installing is not possible because of a corrupt internal memory and hence I want help with installing a rom, from the external sd.

[B]It seems this guide sorts the problem out but could some smart guy please explain in detail or could he just do it i.e do the necessary changes to the rom and upload the link as i am sure many people like me are stuck.
I bypassed dead internal memory on a GT-I9000M.
Symptoms:
- Your GT-I9000M is not booting or bootlooping no matter what firmware you are flashing it with.
- In recovery, you are seeing I/O errors on /dev/block/mmcblk0p1
- Trying to repartition and format the internal storage with fdisk or parted and mkfs.whatever fails.
To recover:
- Partition and format your 16GB+ external microSD with at least two primary partitions, vfat on the first one and rfs (or whatever fs is supported by your firmware) on the second one.
- Acquire a stock ROM, in my case I used JL2
- untar the PDA portion of your ROM of choice (you want zImage and factoryfs.rfs)
- Extract initramfs from zImage ( https://github.com/mistadman/Extract-Kernel-Initramfs )
- grep for /dev/block/mmcblk, there should be 4 .rc files containing references to it as well as within the binary file /init.
- use a text editor to replace all occurances of "mmcblk0" with "mmcblk1" (and vice-versa if you feel so inclined) in the .rc files.
- use a hex editor to replace "mmcblk0" with "mmcblk1" in /init.
- create cpio archive of your modified initramfs with `find . | cpio -H newc -o > ../initramfs.img`
- repack kernel and initramfs ( http://forum.xda-developers.com/showthread.php?t=789712 ), you should have a new_zImage now.
- Mount the factoryfs.rfs as a loop `mount -o loop,rw -t vfat factoryfs.rfs /mnt/loop`
- Modify vold.fstab - this topic is well covered elsewhere (swap sdcard and sdcard1, swap mount points), then umount your loop
- Flash factoryfs.rfs and zImage using your favorite method.
That's it! Your phone will now boot and complain forevermore that the external memory is corrupt. ToDo: use third partition on external microSD as external_sd...

Hi,
I am a Noobie. I have read various threads and came across this thread. I have a dead internal storage. I followed the first few lines, got the custom rom and untared the PDA portion. I have a few questions, from the 3rd line of the above post:
- Extract initramfs from zImage ( https://github.com/mistadman/Extract-Kernel-Initramfs ) [[I created a GITHUB account. How do I proceed with extracting the initramfs from the zimage on my computer. Please explain the steps, bit confused.]
grep for /dev/block/mmcblk, there should be 4 .rc files containing references to it as well as within the binary file /init.[[what is grep? Are these files in the zimage?
- Please explain cpio archive, mount factoryfs.rfs as a loop and also how to modify vold.fstab.
Please explain the steps in detail as the steps are very confusing. I will really appreciate your help
]

I'm confused too, help!
Basically I can't connect my phone to my laptop due to faulty usb connector and earlier I did a factory reset on my phone (Samsung Galaxy SII / S2) but after my phone rebooted, it only came up with the notification bar and a black screen along with the message "Application Installer is not working" so after searching around, apparently my firmware has f***ed up. Now I'm trying to flash the firmware - original or any, I don't mind - via the external SD but can't find an article that's clear so can anyone help?
Thanks!

To solve USB problems try this , since your device is S2, (this is S1 forum) visit S2 forum for better S2 guides ( search under device for your device forum)
To Flash a ROM, you can do it with Odin3 from PC, or on CWM recovery or with Mobile Odin, direct from Phone ( only to get the idea , look here ) but go here for S2 ROM's
If you still want to know how to flash with a broken Sd card check out the guides here

I can understand how irritating it is when we try everything to bring alive our smartphone. Even the Asia's biggest mobile phone market (Gaffar Market, New Delhi) repairmen refused me about the hope to make my device alive. Thanks to @rxxxni which made my phone alive.
Now coming to the point, go to the link:
www.htcmania.com/showthread.php?t=520348
the site is in Spanish language, so enter the link
in Google search and go the link (on a PC).
(Google will show you an option of translating it
in English on the top of the site when you open
it. Now click on the translate and you will be able
to see in English)
There are 2-3 ROMs available for download.
I am more than 100% sure that one of them will
bring smile on your face.
(I think that you are familiar with SD card
partitioning, even the instructions are given on
the site)
If not familiar with partitioning then read below:
The easiest method is to partition the card using
recovery as most of the recoveries ( except
stock recovery) provide an option to partition.
You have to Google search for partitioning using
windows/Ubuntu as I don't have PC right now to
help you. I did by making bootable Ubuntu on my
pendrive. Then I booted in Ubuntu Linux and
made partition by its default program. There is a
video on YouTube which shows how to partition
on Linux.
make sure you are using at least class 8 or 10
SD card with at least 8 GB card. I always failed
with class 4 card.
In my opinion, a 2gb of ext4/rfs + 6/14gb
(depending on if you have 8gb or 16 GB card) of
fat32 partition is perfect for running OS on
sdcard.
In my post
forum.xda-developers.com/showthread.php?t=2276729
, there is given a link of Spanish
website, translate it using Google. (I also included the link in this post. There you find
3-4 ROMs to download.) One of them will surely
work depending on your system layout.
All the best.

Galaxy Tab P1000-Need Rom arabic enabled

Hi Everyone
I recently bought a new Galaxy Tab P1000. Everything is just great, but the problem is that i doesnt support arabic. Letters on websites are disconnected.
What I kindly need, is info on what ROM shall I flash. I've read the the JPJM4 is newer than JPJK5 and its arabic enabled. I dont want an arabic interface, I just need arabic language support.
Kindly provide me with the link to download the ROM from.
I've read that my ROM might be bootloader protected, so I have to unlock it first. Do I have to convert the File system ?
And I have to back up my ROM on the SD also, in case something went wrong.
Do I need to flash only the ROM alone ( using Odin 1.7 + the drivers installed ( I have windows 7 ), or I have to flash something else? I've read about the procedures on how to flash it and there shouldnt be a problem. I've read also that some people flash from the Micro SD attached.
Any helps are hughly appreciated.
Thanks.
Hi, I'm currently using arabic enabled rom from Galaxyer http://forum.xda-developers.com/showthread.php?t=933028
My SGT was not locked so I've no problem flashing it. You will need to unlock your tab first, the instructions can be found somewhere else in the forum. After that, just follow the instructions to flash the rom. I simply follow every instruction and never encounter any problem at all.
Thanks for your kind reply.
1- Im downloading the ROM provided in the link u posted.
2 - I'll install the app that Unloack the bootloader in case if it was locked.
3 - Is it a must to load and flash my kernel using MoDaCo Kernel Ext4 ? What about the PIT ?
4 - Do I back my ROM on SD before i Proceed in case something went wrong ?
Thanks again, its really a good joy to find kind members like you to offer help on the spot

You don't need the PIT file. Just flash the MoDaCo kernel as PDA using Odin 1.7 (do not select Repartition). After that, you don't even need Odin for the rest of the process. Just make sure that you inserted the external SD Card and it have enough free space to backup the applications during the conversion to ext4. Without the SD Card, the conversion won't proceed and you'll stuck there until you insert an SD Card and restart SGT.
If you're already using CMW, then you can do a Nandroid backup of your ROM to the SD Card. If you're not, then don't worry, follow the instructions correctly and insya Allah nothing bad will happen.
-the thanks should go to all those who have done the hard work to provide us with the roms and guides
Urgent help please.
I installed the patch and applied it, the TAB isnt bootloader locked, great.
I loaded Modaco Kernel ext4 in download mode, the Tab restarted. At this point, I disconnected the TAB from PC and restarted Tab in Recovery mode with new ROM zip installed on formatted SD Card ( FAT32 ). Im getting a message :
E: Failed to mount / system (invalid argument )
/system may be rfs. Checking..
E: Failed to mount / data (invalid argument )
/data may be rfs. Checking...
.
.
.
.
File System need to be converted to ext4.
E: Failed to mount /SD Card (no such file or directory )
Cant mount /sdcard
Please Help, Im stuck here.
* The micro SD is 4GB, might it be the problem, does it have to be 8GB ?
i recommend Overcome kernel for two reasons; firstly, after applying the kernel from odin the tab restarts and all filesystem conversions are done automatically with a robot voice narrating the progress! the future additions and roms can be installed from internal storage be it 16gb or 32gb no sd cards required!Plus multiple enhancements like voodo sound mod updated! I installed the galaxyer rom on the overcome kernel!
4GB is fine, I used 4GB too. FYI, the first time I got stuck exactly where you're because I removed the external SD Card, thinking that it is better to flash it without any card. Turns out that the SD Card is needed for the conversion, so I just switch off the tab (long press on the power button), inserted the sd card and restarted in recovery mode and the conversion went without a glitch. But make sure you've charged your tab because the process takes some time.
Hi.
Sorry for the delay in posting back.
Turned out that the MicroS SD was "bad"... Replaced it with another one and the conversion went smooth.. The file system was converted, the backup was made and I chose the new ROM from Micro SD Card. Everything went smooth but it didnt take too much time !!!!
Anyways, its all fine now, thanks all for ur time.

[Q] part of internal sdcard gone

Hi all,
I have some trouble figuring out what's happening with my Galaxy S internal sdcard.
first, I lost part of my phone during a call. phone fell in a rebooting loop. since then ; HELL !
I followed each and every post of about 200 threads to get my phone back like (not limited too) :
- flashed 2.1 (2.2) original firmware with Odin
- flashed all existing ROMS (or almost) with .pit, pda via Odin
- all mount unmount things (now grayed in menu with no available message)
- messing around with adb fdisk, mount, format, etc
- did all possible combination of reset, hard reset, wipe, format from phone or recovery
- tried repartitioning card (with gparted once)
- formating via usb from window 7
well, you got the picture !
now the strange things are :
- phone boot ok with any ROM, now with Darky resurection 10.1
- call, gps, messaging are all ok
- no sdcard visible from within the phone or from windows, so no camera or music or any apps that needs to write to sdcard is possible
- a 2go partition exists on the 16go internal sdcard
- if external sdcard is removed, phone never boot pass logo, although I can go in recovery mode and manage to see all files on internal sdcard with adb shell
- mmcblk0p1 and mmcblk0p2 are only visible when external sdcard is in the phone so I guess the 14go partition failed once to load and system recorded external sdcard as the internal sdcard.
I need a way to put sdcards in the right place as I'm pretty sure the internal one is not fried but only lost a partition probably due to lagfix or a corrupt filesystem.
I'm no expert at all with linux OS or partitioning but I'm sure that's the way to go and I know there's a great bunch of devoted developers in here
PR
ps. I'm willing to pay if anyone can get me out of there FAST
I suspect this could be down to bootloaders, 10.1 requires ficeto JVH base right ? and that requires GB bootloaders, im not 100% sure, ive not used his roms for quite some time.
but im sure your problem lies there somewhere.

phone boot ok with all ROMs with any XXX base I tried so I installed 10.1
whatever the ROM, issues are all the same as mentioned above
this won't b easy
well flash back to froyo or eclair, use a 3 file firmware with pit and re-partition
then when that is successful flash this : http://sourceforge.net/projects/teamhacksung/files/galaxys/GT-I9000_FROYO_FULL_PDA.tar/download
then report back please
you dont have the I9000 M<< do you ??

ok done flashing
manage to reboot phone WITHOUT external sdcard.
still don't have access to the 14go internal sdcard partition, although ROM is installed on it (maybe on the 2go partition).
external card is recognized but only with unmount option as size is indicating 00 (of 16go) so cannot use it to store anything from phone (camera, music, etc) will try a empty 8go
any idea about internal sdcard ?
few more white hairs
you didnt state whether you had the M version of the SGS, this is known for its internal sd failures.
also boot into recovery, is there any error messages ?
I have Vibrant version from Bell, GT-I9000 from about phone menu
still cannot mount external sdcard
recovery report no error so far
the bell version of the i9000 is the one that suffers from internal sd card corruption.
there have been many reports of this, i feel you could be another on the ever growing list.
Have a read of this http://forum.xda-developers.com/showthread.php?t=905975
if that brings you no luck, i would suggest you ring bell / samsung for a repair / replacement

i9000 Bootloop/Internal SD Corruption/Semi-Brick

I have an international i9000 that seems to be pretty solidly soft-bricked. I've recently moved back to Canada from the Middle East and was trying to enable to 850 band so I could use it with Bell. I was under the impression that the Bell SGS and the international SGS were basically the same hardware so I flashed (ODIN) a PDA/PHONE/CSC designed for the i9000m. At the time I was on the teamhacksung ICS.
Now, regardless of what I do I always end up in basically the same spot. After my most recent flash through Heimdall, following the first reboot I end up in 3e recovery with the following errors...
---------
E:failed to mount /sdcard (File exists)
E:copy_dbdata_media:Can't mount /sdcard
your storage not prepared yet. please use UI menu for format and reboot actions
E:format_volume: rfs format failed on /dev/block/mmcblk0p2
Data wipe failed
---------
I've been at this for 2 days and tried pretty much everything. Flashed through Odin and Heimdall as well as from recovery off an external SD. I tried 1-click de-brick. I tried to re-partition through ADB. I get various messages in ADB depending on what I'm doing. Sometimes it's I/O errors and sometimes it says "unrecognized disk label".
I can get to recovery and download so it seems like it should be solvable. My impression is that the partition table or structure on the internal SD card has been corrupted.
Sorry if there is already a thread for this with a simple answer, I've been through a ton and couldn't find anything that worked for me. Any suggestions would be appreciated. I'm not an expert in shell but I can follow instructions. Happy to try anything at this point.
Thanks
Exactly the same issue here, so I'll just wait for a solution here.
I think I saw this problems before. Have u backed up all your data? If yes then do this 3 ways below. If you haven't backed up yet, try to do Nandroid backup from recovery mode and restore it later.
Now try this:
1. On recovery mode: wipe data/factory reset, wipe cache, in advance-wipe Dalvik cache.
2. Remove your external sd card ( put it back later if everything's fine ).
3: Set the USB debugging ON, settings-applications-development.
Hope this helps. If it does, please consider 'THANKS' button
At this point it doesn't boot into Android. It was looping for a while but now the boot animation will start, then the screen will go black and the back/options LEDs at the bottom come on. Anything on the phone is long gone after multiple wipes/flashes/etc. I'm not worried about that.
I'm pretty sure it's a problem with the partition on the internal SD. Does anyone know how to reset/repair the partition table and rebuild the partitions from ADB? Why doesn't that happen automatically when I flash from Odin/Heimdall? Isn't that the point of the "partition" toggle?
Or, could I try to convert the file system as if I were moving from a stock ROM to something like CM7 (ie...RFS to EXT4)? Would that recreate the partitions and fix this?
Thanks
Have you tried to flash a stock samsung firmware for your phone (i9000) and re partition using a 512 pit file via Odin? Have a read of the following thread below to get the latest Stock firmware for (i9000).
http://forum.xda-developers.com/showthread.php?t=1102881
Yep, I've tried several of these across froyo/gingerbread and always end up with an unmountable internal SD card. Just for fun I went and picked another one basically at random (JV6 2.3.3) and it flashed as normal and dumped me at recovery with the mounting sd card/storage not prepared error.
Are there really no takers on this? I keep reading that these are un-brickable if they still start up.
This might be worth a try, failing that you might have to take the phone to a Samsung repair agent.

i read about this problem before on darkyrom i think there was a way to bypass corrupt internal sd and use external one go check there its worth a try

I've the same problem and I've tried everything. Not I'm sure that the internal memory is broken, so I want to use the external sd as internal memory. I'm following your manual but I can't get it to work. I tell you what I've done:
1) I've formated the external sdcard with two partitions: one of 6 GB in vfat format and the other of 8GB in reiserfs. It seems to be ok.
2) I've tried to flash with odin the JVU 2.3.6 version. Here I've some questions: Shall I check re-partition? And apply the PIT file? I've tried all combinations but I still doesn't use the external memory and I get the mmcblk0p2 error...
Any help?
Here I have posted how I have solved my problem of corrupt internal memory. Look at it and I hope someone will help.
This guide install rom to SD Card, but still have question, how to repair internal memory? i`l boot`ed rom from SD Card, but cant see internal memory, use camera, etc. who need internal memory...
Maybe are any app to fix internal memory, when android boot`ed?
In most cases I have met (including Galaxy Tab P1000 and GT-i9003) with internal memory failure or corrupted memory, the only solution is to replace the chip. If you've booted your terminal and can not use the camera or see the internal storage, you have to modify the file vold.fstab according to your android version.

Also new to android, but I know linux well
modemfs seems like another partition on the internal storage
since you reflashed this it might be in the wrong format / filesystem
my phone reports this entry in the fstab (mine is ext4 format)
/dev/block/mmcblk0p12 /modemfs ext4 noatime,nosuid,nodev,journal_async_commit,errors=panic wait,check
you need to flash one in the correct filesystem, maybe try one of these from http://forum.xda-developers.com/showthread.php?t=2526831 not sure if these are odin compatible
if all else fails you can download the stock rom from http://www.sammobile.com/firmwares/
thanks for your help
thanks for replying, and sorry for the late answer.
I will try the link you sent me, but there are a couple of stuff i failed to mention last time, before showing me that it used to show failed to mount /data and /sdcard .. I think the internal sdcard is damaged because I did flash the stock rom, the phone boots without the ability to install any apps, no network, yellow text is displayed on the screen saying stuff like PDA and Csc .. etc, inside settings baseband is XXXXXX. also when I connect the phone to my windows ... the internal is empty with incorrect size and you cant create or copy folders in it and was not able to formate it in windows or linux .. even recovery was not able to formate it.
update: I did try one of the files, but it is the same unfortunately .. I think its the sdcard issue .. but that is ofcourse my humble opinion. any other solutions ??

I seriously doubt that the internal memory itself is damaged. If you were able to flash anything then it still works.
Or are you referring to the removable SD card? Via USB connection none of the storage size is also not reported correctly on my phone.
What recovery do you have installed?
1. Firstly you should get the phone working again and work off WIFI.
I am not sure if the stock rom installer only copies files or if it dd the whole image (incl filesystem format).
Your IMEI is stored on a filesystem and mounted on /efs - You should not remove / format this filesystem !!! Do not even touch it!
When you installed the custom rom intially you probably formatted in the f2fs file system? I would install the custom rom again, and in the install menu format "data" and "swap" to ext4 filesystem just to be sure.
Flash back to stock make sure about model and baseband
The phone should boot up and at least be able to install apps via WIFI.
I installed the app "ssh/sftp server" and then login via ssh to browse and inspect the phone.
2. Step two is fixing the baseband (not having any network signal)
2.1 What is your original baseband?
2.2 What phone variant do you have 8190/8190L/8190N? If you flash a different one to your phone it will not work.
I mean the internal sdcard, cause previously it showed unable to mount /sdcard, right now I have the stock rom, each time the phone reboots, it resets itself again, all my changes are gone, yes I can turn on wifi but no apps are to be installed, using pc can't copy anything to the internal storage (I can only copy on my external card which I use to flash) right now I have TWRP and I tried CWM as well. as for installing a custom ROM, it didn't work, the phone doesnt get past the s3 mini logo, only the stock rom passes through, my phone is 8190 and I have no clue what is the original baseband um really sorry I am a total noob. I will try again to flash the customer rom using Odin and will get back to you.
thanks so much for going through the trouble.

Is
The baseband is linked to your country, it specifies the frequencies that you are allowed to use to communicate with the cellphone network. So If I know what country you are from we might be able to locate the correct Stock ROM on SanMobile. You might be flashing a wrong stock rom to start off with.
What country do you live in and what network operator?
Are you using ext4 filesystem for data and swap?
I personally used twrp 2.8.0. I think this is the way to go.
Do you know Linux?

Need help mounting /system and /data from external SD. Internal SD is dead :/.

Hello,
I normally can get by pretty well, and I have done numerous searches before posting for help. This time I have really run into a brick wall, and I really need help here.
Basically, I did something really stupid where I did not know that the phone had been booting off a external SD (my mom gave it back to me like that). Actually, I suspected that it did because the phone would have not booted without the card, however, I could flash my phone even if I removed the external SD card (as if the internal SD were there, but it wasn't), but it had always required me to insert the card back in for it to reboot from a flash. So I thought maybe internal SD was fine.
Originally, I had a Samsung 8gb class 6, but I wanted to change it to a 32gb class 10 ( to help the OS run smoother IF it were running on external SD). This is where I made a great mistake; I formatted the 32gb card and made 3 partitions. The first one is in FAT32 of 24 gb, 2nd is in EXT4 4gb, 3rd is the rest in EXT 4 as well. The original setup that was working had about 5.5gb in FAT32 and about 1.88gb of EXT(not sure which). The mistake was that I also formatted the 8gb card as well. In chronological order, these were what has happened:
1. I did a Odin stock reset to 2.3.5 with CWM injected
2. Installed Corn Kernel
3. Formatted both external SDs and repartition as mentioned above
4. At this point, I didn't know there was an issue. CWM sees the external SD and I tried to install CM 10.3 since I read in one of the threads that JB has a weird file systems and it needed to be installed twice to fix sdcard0 and sdcard1
5. CM10.3 installed kernel, and failed afterward since there was no /system and /data. At this point, I have Neat Kernel installed and lost bootloader along with fastboot and cannot access download mode.
6. I have tried to change EXT4 to EXT3 or EXT2 to see if there would be any luck in file system recognition, but no luck
7. The only way I can connect to the phone was through ADB, and verified that my internal SD card was dead because mmcblk0 was not there when I removed external SD
8. I tried to mount mmcblk0p1 (4gb EXT4 partition) and mmcblk0p2 as /system and /data, but I had been getting an error
9. I tried to use USB mount in TWRP, but no additional drive showed up (confirmed dead internal SD)
9. I tried to look for vold.fstabs but /system does not exist. The only *.fstabs file founds were in /etc file (not /system/etc) and is, for example, aries.fstabs
I know for the fact that it can be done because the phone was working before, but I really don't have enough linux knowledge or the what the phone looks at in chronological order in order to figure out how to remedy this. I would really appreciate if someone can guide me to a right direction. Thank you.

I see it's been a couple weeks with no update but if you're still stuck this may help. I had similar issues trying to flash zips from recovery. I kept getting the "can't mount" error message and what I figured out is that the access to CWM recovery via the update method I'd used was pretty much loaded up in cache, thus I couldn't mount . Getting back to total stock first may help. This is the basic rundown I performed to get my cappy back up ... currently on JB. Granted, I didn't go about reformatting drives as you did.
1. Flash I897UCKK4 with Odin (no root) for gingerbread stock rom
2. Download and install KK4root. Run Kk4 root "run" exe in the kk4_root folder. Corn kernel is installed with modded recovery system
3. From Corn kernel recovery click "root extras" to get su and busy box installed
Everything is pretty much dependent on using them in Windows and still active in download links if you do some searching.
Hope it helps!

Thanks for the reply; I constant checked this site for a week or so with no response, so I gave up. I would have been able to go with your method if my download mode worked. Basically, I cannot go into either download mode or fastboot. I tried to flash different kernels to try to enable it, but I kept running into error 0 even after I changed the binary. Any idea? Thanks.
