[Q] PIT Repartition VS EXT4 - confused

I recently bricked my phone by installing 2.2.1 over 2.2.1 + Voodoo lagfix, ie, I didn't uninstall voodoo before flashing 2.2.1 stock again. I got around it by using a JM8 pda + JM4 modem and a 512 pit repartition, then going up to 2.2.1 again using just a PDA with no pit/repartition.
I was just wondering, since I didn't technically remove the EXT4 file system by uninstalling voodoo, how did the system get converted back to RFS (or did it...)? Basically I'm asking about the relationship between the PIT repartition and the file format the phone uses (does repartitioning ALSO reformat the internal SD)?
My quadrant score is around 1100-1200 running stock 2.2.1 JPY, so I know the system is back to RFS (as opposed to the 1800 with EXT4), but will there be any little 'gremlins' so to speak in the future? Phone is working fine as it now.
Any replies would be appreciated!
Thanks

When you use PIT file, it removes any modified file systems, its essential to remove lag-fix before flashing, but sometimes we forget... luckily its not the end of the world.. a few flashes with different firmwares and all is back to normal...
its just a pain in the arse having to do all that so that's why we remove lag-fix first...
but it doesn't affect the internal sd card.. so you shouldn't get any further issues..

Thanks
I was reading up on some other thread, and that's exactly what I thought the PIT file does. I was just confused because normally when you re-partition something it doesn't automatically format in PC's, but apparently Samsung is nice enough for the PIT's to partition + format for you.
I tried reflashing 512 pit repartition + 2.2.1 at first and that didn't work... Now I'm wondering why rolling back to JM8 with repartition THEN to 2.2.1 without repart worked if they use the same PIT In my mind repartition would simply wipe the file system and set up the partition for the OS/kernels and 2.2.1 would slot in nicely... Apparently not.
Funnily enough bricking my phone doesn't scare me, but not understanding what the hell is going make me wants to cry though. I actually locked my usb cable inside the product box until the next XEU update comes out, haha. Phone reception is just as crap with the JPY version vs the old VAUJP4 (vodafone australia froyo) but loading apps, contacts, etc seems much faster.
On a tangent I went to get my contacts off an old inactive 3 SIM, and noticed I was getting like 4-5 bars (around -80dbm signal) with HSDPA as the mobile network type (emergency calls only). With the default vodafone sim the network type switches to UMTS with something like -105dbm with about 0-2 bars normally. I don't use data on my plan (it's like 100mb... don't wanna incur ridiculous charges if I go over), and the voice quality doesn't seem so bad... but is there any way to get better reception, ie switch networks. Kind of clueless about this stuff as my old k800i had 5 bars all the time!

i am with vodafone UK and i have terrible 3G signal.. i only use GSM now and i always have full signal, and data connection (2G) isnt super fast but it works everywhere. Perhaps you could try it
and as for rolling back to JM8 firmware, JM8 includes 'dbdata' which is what gets corrupted alot when flashing all the time, causing errors and boot loops, thats why so many people recommend it.
but you can go direct to the latest 2.2.1 from JM8, so its not too bad i have bricked my phone many times in the past fortnight, but thanks to XDA im still up and running

I did a little digging again and turned up the same conclusions about the dbdata file. Apparently all the froyo versions don't have this dbdata.rfs file (that JM8 does), so when I repartition straight to a 2.2.1 rom everything was deleted from the repartitioning and is copied without the dbdata file, bricking itself.
But if I go from JM8 > JPY without repartition, I'm assuming all the OS/kernel/modem crap from the JM8 is overwritten with the new JPY files, but the other required systems are left alone. I guess Samsung only updates/creates the files they need too... I'm assuming all the 'sensitive' folders in root like /efs (where your IMEI is) are left alone by the reformat/lagfix? I still have my original one so it seems as if this is the case. I've read about some 'leaked' ROM's that actually change your IMEI number, and I guess they just over-write this folder when they are flashed, instead of leaving it alone.
Makes me wonder how they actually get stock 2.2 firmware on the phones in the first place. They probably use some JTAG system to do it en-masse, but it doesn't change the fact that they have to add random files in order to get it to work or actually have to do it 2xfold. Why couldn't they just include all required files in official roms, regardless of if it isn't updated, rather than making it like assembling a file system jigsaw puzzle.
If we ever get gingerbread, I bet there's probably some file/directory that 2.2 introduced/took out/changed and I'll have to flash my phone 3 times from 2.1 > 2.2 > 2.3!
The feeling of understanding the how/why's of unbricking is actually the same level of relief I felt when unbricking my phone... I'm happy with performance for now, the stress of this is too much to continue messing about with ODIN and ROM's. I think I'll stick with Kies and stock XEU firmware for now (doubt I'd bother with any local australian roms, all are branded bloatware, and XEU gets updates faster!). Kind of freaked out about the IMEI changing thing after some forum searches now (given that I don't wanna mess with odin to root my phone and back up my IMEI file, I might break it again, haha!) so I think I'm done with flashing. However...I have this urge to fiddle with my phone even though it works perfectly fine (and stresses me out unbelievably waiting to see if it works) and I'll probably do something worse this time... I want a totally unbrickable droid to fiddle with, haha. The open-source thing with android is nice and all, but with PC's you usually don't take a trip to the service center and incur a $10-300 bill when you **** up a piece of code. Most motherboards have a literal ROM that stores back-up BIOS settings so you can NEVER brick your computer short of ripping the backup BIOS out of it's socket...
I totally need to destroy my USB cable...

IMEI is fixable if it gets corrupted, im sure i seen a thread about in on here, along with a million others lol
I would recommend Odin over Kies anyday Kies is responsible for A LOT of bricked phones, i mean look how many thread there are on ' Help Kies bricked my phone' you dont see as many for 'odin bricked my phone' (unless the user doesnt know how to use')
What ever problems you run into, i guarantee someone has already run in to it, and i bet there is a solution too,,, If your looking for an 'Unbrickable' Droid... its sitting in your pocket !!!
its upto you to give up the whole Hacking + Modifying thing, but me personally,,, Never ever,,, dont give up on your phone.. all it takes is a 10 minute read up and your questions will be answered.

[Q] I screwed up (almost no more data)

Hi,
I don't really know what I did, but I can't get any data connection anymore.
The phone was really slow to get data, when It gets it.
It tried to put back a modified nv_data.bin
I have the 3G/H icon, but it stay grey.
I've tried to reflash stock (with clear efs) try to reflash CM7, try to change modem, tried to restore my nv_data.bin which I backed up.
I've tried to "restore original settings" from network menu.
Under stock I've tried to modify the CSC (with the secret menu). I've tried to put a modified nv_data.bin
Nothing work. I don't know what to do know
The icon stay grey, and sometimes I can load a web page (but awfully slow), sometimes nothing work.
Any advices ?
Many thanks in advance.

Have you checked your apn settings?
GTi9000 insanitycm010/insaneglitch

Hi. Yes i've checked APN. For now it's working. But when i reboot, it take at least 2 min to hang up to the network, i mean activate the data.
Could it be my operator blacklisting me or something due to nv_data change?

Try to flashing stock rom with .pit for new partition some case it will restore your nv_data.bin if there is still alive in system and didnt corrupted

Thanks.
I'll try that again (already flashed stock JPU with .pit and "Clear EFS" checked)
For now it's kinda working. But sometimes i suddenly have no network throughoutput (but icons stay green)
I'll check that

Hi.
I've tried going back to stock and everyhting.
Data comes but it really slow to acquire network.
Is there anything else I can do ?

RESOLVED [Q] SIM not detected?? (ATT + polish GNOTE)

I got a GNOTE from negri on 11/9. It seems it was s polish version. It has been working wonderfully on ATT (after adding in APN manually for 3g/H+ -- voice worked out of box).
I rebooted Today (11/13) and now it has the crossed out circle instead of bars and says "Insert sim" when I start to do cellular related activities.
I have Seated and reseated; nothing. pulled the sim and put back in my SGT (phone enabled) and it works. Put back in GNOTE, still no sim detected! Stuffed SIM in my N1; it works.
Any suggestions?

I had a similar SIM card issue when I tried to activate the 1700MHz band in Service mode (for fun). Wipes and stuff didn't solve anything. The way to revert it for me was flashing a full stock Samsung firmware in Odin.

Can you provide more details on how you did this?
Where does one get a full stock sammy note firmware?
Are there some good instructions on this?
I have flashed my SGT via odin several times. Same odin? Same process?

In the development section you will find some versions.
The key for me was flashing a new Modem (Radio/base band) image via Odin I think. I changed Kernels and ROM's but only flashing a ROM including the Modem got rid of my SIM issue. Not sure because in the end I flashed a full N7000OXAKJ1 firmware in Odin from here:
http://forum.xda-developers.com/showthread.php?t=1310513
It did the trick, though the tread is dead. I think any ROM including Modem might help, I currently running the 2.3.6 N7000ZSKK1 firmware and it is great, also included a Modem.

when this happened to me, also due to turning on 1700, I was able to reset my phone by doing a factory reset. Unless your modem.bin is corrupted, you should not have flash a new rom.
- frank.

ugh....
you mean factory reset via Settings->Privacy->Factory Reset?
Tried that... No affect. Is there another way to do this?
Was hoping to fix w/o the flash. NOTE: I did go into that service menu with the 3G Freq are listed. I was curious when I saw the post. But I never changed anything. Just saw the screen and thought "neato". I wonder if there is another service screen that has an option for 'unfuck'???
Still searching for answers, before trying the ROM route...

OMG I have the EXACT same issue as you, and I got mine from NEGRI also! It was working perfectly until last night --- all of a sudden I got that circle and I've been trying to fix it since then! Please keep me posted if you find a solution, I was going to try and contact Negri tomorrow for an RMA.

still nothing.
I did a root. No changes...
I did a rom flash of kk1 ... no changes....
I was trying to reflash the modem with KJ6 modem....but have a signature failed problem...
now what???

I solved my issue by a combo of those steps.
I did full flash in Odin of jk1. When I rebooted that didn't solve things so I wanted to flash the other recommendation, kk the Chinese rom.
Upon entering recovery I noticed I lost 2e and was on 3e. So I had to download chainfire's rooted jk1 kernel and do that zerg rush to get root. It was while I was doing that that suddenly my similar got recognized. By the time it finished installing the rooter kernel I had full reception again. I flashed kk just for good measure and its been smooth since. Hope it works for you too and I'd love to know what the heck broke it in the first place??

hi fwelland, it's hk1981...so you tried the rom flash and it didn't work?

Hi hk1981,
No the KK1 rom flashed fine. By all accounts it works well, except that pesky phone part. This KK1 rom is really 'clean' and very little bloat-ware and it installs a vanilla boot animation (not a carrier one). All that is nice, but didn't help my problem
I did notice a peculiar thing: while in recovery (android recovery, not cwm) I get some warning about "CSC something or other, fixing".
I have a short list of things to try before I have exhausted my DIY options -- the post just above looks promising.
I think the answer is out there. We just need to keep looking and keep attention on this thread and others like it. This place and others like it are a huge help and I'd like to solve it and then give back a good set of instructions.
FWIW: I wonder if there was some voodoo in the polish rom that caused some issues in the modem when a different than expected sim was installed? Or if one of those funky polish apps that updated it self before I could turn off auto-updates has something to do with it (doubt this -- I don't think apps can do stuff unless rooted...)...
Still searching....I got this other pesky problem to deal with now: w-o-r-k

I had that problem too, it doesn't detect that CSC and then goes ahead and applies something. Check to see if you are in 3e recovery, I think you are after having flashed vanilla JK1.
Re-flash Chainfire's rooted kernal for your appropriate version and then go back into recovery and it should be 3e and you can flash thru CWM then.
Also note; each time I flashed, I also wiped data/cache/davlik just to be sure.

yes it does say:
Code:
Android system recover (3e).
So I will need to try the methods you (crippenx) suggested.
FWIW, the CSC message that I get when I first enter recovery is:
Code:
# MANUAL MODE #
--Updating application...
Successfully update application.
--Appling Multi-CSC...
Installing Multi-CSC
Applied the CSC-code 'TGY'
Sucessfully applied multi-CSC.
I have no idea what this means. It does it every time I enter recovery.
FWIW, I never flashed this gnote with ODIN (I have used ODIN on my SGT several times). I got to KK1 by first rooting via http://forum.xda-developers.com/showthread.php?t=1329360 (using 'forget the above steps') and then using the CWM 'kk1-wipe.zip' from here http://forum.xda-developers.com/showthread.php?t=1342797 -- I didn't use ODIN to get to kk1.
I see on the Root/Unroot thread, there is a KK1 kernel option for 'simple'. I think I will try that with rooted already script.

My rough guess is that the phone has a list of 'valid service menu options', and it cross references it with what is on the SIM card.
Once the phone decides it's not going to read your sim card, the service menu is blank. This is a real headache.
That's why once I set the 1700+2100 combo, and my phone boycotted my sim, I wasn't able to set it back.
That's really dumb, imho, to have a one way toggle like that. I'm fine for settings to enable/disable other settings, but for a setting to disable itself? ugh.
I would really like to know what's going on. I was planning on switching to AT&T before my next trip (which is soon) but I can't risk my phone glitching out like that during the trip.
Actually, the ROM is on my SD card so I guess it wouldn't be THAT horrible, but it's certainly not something I want to do. Perhaps we just need a way to flash back the modem.bin, assuming it's corrupted.
- Frank

Sorry typo on my part. You are in 3e recovery because of that base flash, now you need 2e recovery which you can get via chainfire's rooted kernel. His installation procedure runs a batch file that uses that zerg rush exploit which I gather is partially from gingerbreak. It was during this procedure that my baseband suddenly came back, my sim card finally detected.
Once that was done, I entered 2e cwm with volume up,power,middle button and did erase of data,cache,davlik and then flashed kk rom via zip file.

For me flashing all partitions via Odin worked (no pit file or repartition). Tried all sort of stuff from recovery first with no result.
I don't know what partition flash from Odin did the trick, but you could try Odin flashing a Modem separately and check if that works. If not try the rest?

Finally got back to this.
After much fusing I finally got KK1 and cwm working. It was odd, I had to re-run the whole root process again.
At that point I could apply the KJ6 modem w/o any problems (via cwm)
no dice!
Still dead!
Not sure where to go next???
Can some one provide a few details about flashing a modem,rom and/or kernel via ODIN? Perhaps that method will work....

Oh when you flashed jk1 I assumed you did it the old way via Odin and the multiple files. That's how I did it and you're right, that may be what fixed it as when I used to brick my sgs and sgs2, it was always a full Odin flash of stock that brought it back from the dead
To flash in Odin put your phone in download mode. Fire up Odin. In csc point to csc file. In phone section point to modem and for PDA you point to the code file. Don't put anything for pit or bootloader and unchecked the repartition toggle.
Connect your phone and wait for Odin to detect it and show yellow in the status window. Press start and you're good to go. Hope this does it!

[Q] {SOLVED} IMEI blank after flashing SlimICS through CWM

- SOLVED! Flashed a different ICS Rom along with Semaphore kernel and everything works again!
Hey all!
I have a BIG problem... Yesterday I flashed SlimICS 2.9 on my friend's Galaxy S device through CWM. Installation went fine and system booted up OK. I quickly noticed that there was no mobile network available and I went to check the IMEI as I was suspecting the worst. The IMEI showed up as blank on the phone...
I checked the /efs folder and all the files were present (nv_data.bin and such). I also noticed that there was a /efs backup on the internal sdcard. I tried overwriting the files from the backup to the /efs folder on the root to no avail. Upon deleting the /efs folder or any files in the folder, they are automatically placed back. Why does that happen?
I cannot use the phone's usb port since it's broken.. so all has to be done from within the phone. (External sdcard still functions, ofcourse).
Spent a lot of hours searching and reading - I'm desperate!

There is an app "Mobile Odin" .. us this to flash stock firmware on your friend's phone.. I haven't used this app myself but it should work.. you can download the stock firmware from sammobile.com .. once you flash the stock firmware your IMEI number should be restored... then you can try flashing rom once again
PS: Please don't offer money like this.. donating to the developers of Roms and apps is enough.. they are the ones doing the main stuff..

Didn't know that Mobile Odin existed! Seems like a great program.. I installed it and upon opening it tells me that ''A compatible device was detected, but with unexpected partition layout. Mobile ODIN cannot operate. This is a common error on CM and MIUI ROMs on some devices.''
What ROM would I flash through CWM to get this app to work for me? Is Mobile ODIN incompatible with ICS?

UPDATE:
I flashed a different ICS Rom, Codename 1.5.6, and now the IMEI shows up when dialing *#06#! I was also able to unlock the SIM!
EDIT:
I was able to call! However Data connection does not work! Even with the right APN settings... Would this be caused by the firmware?

dont worry,i had the same bug.you have to flash another kernel,Glitch,or Semaphore for example...then you will get data connection

[Q] "Unknown volume for path" - can't get Download screen

I attempted to restore a backup via CWM and now I get the message E: unknown volume for path" in response to any options in CWM. If I try to reboot normally, I just get the SGS splash screen, which just stays there.
I can't get to the Download screen with the three keys, this just gets me back to CWM. So I feel pretty screwed now. I could order a jig but will it even work in these circumstances?
The sequence of events that led to this was that I followed the instructions here to install Jellybean 4.2. All went well, Jellybean was running very smoothly from this rom. The trouble was that I just couldn't get it to find any mobile networks at all, even when I manually entered the APN and VPN etc. My sim is a giffgaff one, which uses the O2 network, and you do have to add the APN to get the 3g to work - but the phone just wasn't seeing any networks at all. I presume this was because this version of the rom just doesn't recognise UK carriers.
So anyway, I then went into CWM to restore my last backup, which was from over a year ago. This all appeared to work but then it got as far as the SGS splash screen, as described above, and stayed there.
What else can I try?

Well, I did manage to get a Download screen in the end, although Odin running on my Win 8 desktop couldn't see the phone. However, I then put Odin on my netbook running Win XP and that can see it.
So I'm now ready to flash a stock rom to the phone. I've tried following PuggeredUK's guide to installing a stock rom, which I've used successfully in the past, but he does say you need a .pit file. I've tried loading a stock 2.3.4 and 2.3.6 value (which was the last stock firmware I had on the phone) roms from Sammobile but can't find any .pit files in any of the stock roms I've downloaded from there.
So are .pit files actually necessary? I tried sending one file to the phone and Odin said "Failed", so I thought I'd better check about the .pit files before further buggering up my phone.

I had this same problem too when I restored my backup. I got it fixed by just going back to the ROM what I had before I tried to restore. (which was CM10).

Do what I just told this guy in post #7
http://forum.xda-developers.com/showthread.php?p=38194645
Edit: and you lost your network because you flashed from GB to JB, missing out ICS. Nothing to do with the rom and uk carriers. Next time install ICS first.
