I would like to install CM7 from http://forum.cyanogenmod.com/topic/...f0000dangerous-test-releasecolor/#entry148754
But to restore back to Froyo, it says to use ODIN to do a restore with the re-partition option. I thought I read that the re-part option would brick a SGH-I896.
Is this correct? or am I just imagining it.
In other words, does the repartition option work properly on Rogers SGH-I896?
Thanks for any answers you guys give.
You want to run an experimental beta ROM for an i897 phone on your i896? Trying to find the fastest way to brick your phone?

I do not believe it will brick the phone. The board is an I897 with slight revisions. I was just wondering about the method used to go back to froyo. I am not a complete noob and am not worried about bricking to install the rom. Just going back.
But I do appreciate your input.
DO NOT USE PIT / RE- PARTITION ( the p in PIT is for partition )
i did that and on reboot had an error
E: cant mount dev/dbdata...
was STUCK. only option was to do ONE CLICK ODIN, even after flashing EVERY AVAILABLE rogers stock image, on the net and my own, I CANNOT GET RID OF ATT bootscreen without the cheap hack of replaceing the ATT image with the origninal (still named ATT boot).
the CM7 is still not ready, you will just be going back to what you have now,
WAIT for it to be ready.
Everything I've read on CM7 up to this point is that it is not yet ready for use other than for developers trying to fix its remaining bugs. A number of threads opened up on it over the past week have been almost immediately closed because of the potential to mislead people to try it and end up with bricked phones.
I flashed there and back with no problem. I did not use the re-partition option to install.
Well answered

Thats what I was afraid of, I didn't want to be stuck with att junk on the phone.
Guess i'll wait a little more, sad to say I can only play with gingerbready on by HTC Dream . for now anyways.
Thanks for the answer
Cm7 is largely stable with some bugs. If you do not read the known issues some funky stuff will happen. Speaking from experience ; ) it is everything the hype says it is. Running since the morning. My one concern is battery but I need to let it cycle a couple of times.

Been running CM7 since late January, and did some of the early dev work on porting it to the Captivate. I have an i896. Trust me, it won't brick it.
To op, there will never be a non-one click revert. CM7 changes the setup of the mtd blocks (basically the nand where the rom is installed), meaning you MUST repartition to go back to a Samsung rom. However, none of the Rogers images contain all of the rom, meaning if you repartition, you will be missing parts of the rom, and will just bootloop/be stuck in recovery.
Tl;dr: If you flash it, and want to revert, you must use one-click, and that won't change, even when it's at "stable".

Best advice, straight from the source. And OP, as was said before, make sure you know what the known issues are. The CM7 thread has a lot of complaints about issues that were already noted and known. If you can live with those, jump in!
OK fellas, I have a brand new Captivate. Build is 1102. The phone shipped with 2.2. I bricked the first one so bad I had no choice but to replace it. The second one was almost to that point before I got Odin 3-click to get back to stock 2.1 update 1. Now I'm trying to get back to stock 2.2 and I can't seem to find anything relating on how to do that from my situation. I have literally been up for 38 hours working on this. Took me the first 24 just to get 2.1 on it. I am really stuck here. If anyone has a tool, or a guide, or a hint or a .9mm that can get 2.2 on my phone, please throw me a freaking bone...
Thanks in advance
up for 36 hours isnt going to help.
go get some sleep. come back later.
wait...
you are on your 3rd cappy and still dont know what to do?
Wait so it came with 2.2 you used odin to go to 2.1 and now you wanna go back to where you started?
Ummm ... have you tried kies mini?
When I couldn't use Kies Mini to update my phone from Eclair, I used ODIN 3 (not one click) to upgrade to Froyo - using the image found http://forum.xda-developers.com/showpost.php?p=11526718&postcount=1
My build is 1011

Im on my second Captivate. I was actually able to bring it back from brick by building a jig.
@studacris::: It came with 2.2, i flashed a custom rom which was giving me problems, tried flashing back and it failed leaving me with a brick. Built a jig and flashed odin 3-click which put 2.1 on it. I tried to use mini kies but it says my phones firmware is unregistered and will not let me update it...

turn on usb debugging before you connect it to kies
i have not tried the following link but I saved the file just in case I needed it. According to the post that I download the file from, it said its supposed to take you back to JI6:
download here
just be careful because I did not test this file myself
Use the jf6(2.1) odin one click and then there is a file you can use in the odin standalone to get you to kb1(2.2).

Please push *2767*4387264636# or download SGS Tools and select the second option in the Secret Codes section. This will output your product code. If it says anything other than SGH-I897ZKAATT, your product code has probably been tainted, which causes the Kies "unregistered device" error.
The reason this always happened for me is that the product code was changed by the custom ROM. If you do not have a backup of your EFS partition, then correcting this will require a hex editor. I used the method described here - http://forum.xda-developers.com/showthread.php?t=880223 . Messing around with EFS is inadvisable unless you know perfectly what you are doing. (Trust me on this as Sammy has my first phone for this reason alone.) It wont hurt anything to have an incorrect product code, aside from not being able to update to new software through Kies, but if you mess up anything inside of the file that is edited during the process in the forum link listed above, your radio firmware won't know what its own IMEI is. This can cause your phone to stop functioning as a phone.
The first thing that you should do before flashing any ROM is to backup EFS. There is a method for that here: http://forum.xda-developers.com/showthread.php?t=859914 . I backed up EFS using every backup method described there (there are two or three I think), then I copied those backups to every thumb drive and storage device I have. I always have restored using the "tarball" method and have used Kies to get back to 2.2 about 20 times without the "unregistered device" issue.
So the most important question is - Do you have a backup of your EFS? (please say yes) If so, then it is just as simple as restoring EFS.
Another possibility if your redneck.nerdishness extends to Linux usage is to use Heimdall for your Froyo upgrade. I used that on my phone when Kies mini was failing on me. Search for Heimdall in the Captivate and standard Galaxy S forums, then follow the instructions to use it with the stock update.zip file linked in the forums.
Hi, the title says it all. Is it possible to restore imei and efs on a samsung infuse with unbrickable mod applied? Or unbrickable mod only possibility is to reflash the firmware? I mean i know that unbrickable mod is used to be able to get the phone on download mode but. Is it able to flash something to fix imei? Because i have tried just about everything to restore my Infuse imei with no luck. I know there are advanced tools to do so, But i was curious since Unbrickable mod go so deep in terms of changing that sequence i may be able to repair my imei somehow with it.
I posted an EFS repair file sometime back. It's either in a zip or a tar.
Do you have an idea on where is the file located(what thread)? My imei shows as null. I guess ill be able to fix it with that file right?
By the way, pretty cool to find another old school guy in terms of pcs. My first computer was an atari 400. Had a lot of fun with machine language and basic also. Every time i managed to draw a simple line with commands or maybe just saving programs using an old school tape recorder which was the old version of what we call cds and dvds nowadays ha ha... Oh that brought me some memories ha ha
Hey Truckerglenn, sorry for bothering you but i went thru every post you have made(all 19 pages) and i didnt find an efs file. Maybe its been deleted or something. The only thing close to that issue i found is the Restoring a dd backup with Odin (A fix for a badly broken EFS) thread but no file there. Maybe you can help me find it
Nevermind Glenn, i already found it. In case someone needs it heres the link to that thread:
http://forum.xda-developers.com/showthread.php?t=1438113
Didnt worked for me, but maybe some lucky guys will be able to fix theirs with that file....
Sorry that it didn't work.
If you had an Atari400, then you'll remember the Happy boards that we used to put in the old 1050 drives. They made such a racket, but you could copy any copy protected disk.
Hey Truckerglenn, finally i managed to make it work!!! Wohoo! Im very happy, So when i was going to give up, i decided to give it a try again and heres what i did for the rest of the forum in case they have the same situation and want to give it a try:
I openned ODIN and clicked efs clear, I know its not recommended but i didnt have anything to lose so, I used the infuse unbrick files to take it back to FROYO, pit, pda and phone. Then i use your efs file and dropped it in the csc box. The phone flashed. And when it went into recovery i gave it a factory reset and rebooted. When it turned on Make shure enough it looked like nothing happened. But a couple seconds later the phone did have its signal and the baseband version was back also. I know its weird, but it worked for me. So if you have a phone showing no imei and baseband unknown why not give it a try??? You could not damage it any further than you already have!!!!!!!!!!!!
Great glad it worked. It'd been so long, that I'd forgotten the steps that I used. But now that you mentioned it, I do remember having to wipe the efs from within hemidal or odin.
I'm planning my escape from the digital world!

I'm glad you got this sorted out, enelyam.
I'm gonna post a link to this thread in the HOW TO thread I started so it can be reference for anyone else later.
Thanks for posting your results.
Add a [SOLVED] to your thread title so some other unfortunate soul (not wise enough to have 10 EFS folder back ups like me) who borked their phone later can find it too.
Thank you all got my imei back.
I have already hit the thanks button but felt compelled to write it here as well.
I was really hoping this would work for me, but when I dial in *#06# I get a "IMEI NULL/NULL" pop up. Any other ideas that could possibly work for me? I really don't want this phone to end up being just a music device.
didnt work for me either

I have tryed everything and didnt work for me either, my only hope is to go to my moms tomorrow, my lil brother has a worrking infuse, i'll try something maybe ill be able to fix mine..
Alright, so i am having a bit of an issue. And it's probably because i'm a complete noob....
So, I have a new GS3, and wanted to give my (already rooted and flashed with Cyanogenmod 10) Skyrocket to my mom to use on Simple mobile (a company using T-mobile's towers).
I read that you can flash radios for T-mobile onto the phone, and so I figured everything would work.
Here is what I did.
I unlocked the phone while in Cyanogenmod10
Flashed LiquidSmooth RC9 - read it had less bugs
tried flashing multiple Tmobile Radios
I get NO service. I cant pick any of them up..
Baseband comes up as UNKNOWN...
So i'm currently downloading ODIN and going to try to flash to stock and just start from scratch...
Any suggestions on what to do?
Do you still have an imei?
Try unlocking the phone after you've gone back to stock. I don't know how you did it with cm10. I don't think it works with anything but stock.
Sent from my SAMSUNG-SGH-I957 using xda app-developers app
No, the IMEI is blank when i do the *#06# code....
also, when i put the simple mobile sim in the phone, it automatically came up asking for the network unlock code. That's how i was able to unlock it.
Did you ever backup your imei? Flashing back to stock will hopefully bring it back if not you may have some issues. Also as mentioned above it's better to unlock from a stock ROM or at least stock based.
Alright, Flashed to stock, IMEI is back (thank god), and i'm getting service.
Now here are the issues ahead of me, and any help would be greatly appreciated.
I am on STOCK ATT ICS Rom.
I GET SERVICE (however, it's only 2g) i know i need to flash the radios for Tmobile,
Was going to use this ---> Blaze_4G_LB7_ICS_Radio_MOD ...... Direct DL, CAN BE USED FOR T-MOBILE/WIND ON ICS (from the skyrocket reference thread)
First i know i have to root, install CWM, all that.
Now, should i flash a custom rom? If so, which one would you suggest. ( i assume, i have to give her ICS, not JB, right?)
Also, you said backup my IMEI, i'll look this up in the meantime, but if you could include a link in your post on a how-to just in case i dont find it, i would really appreciate it.
Also, is there anything else i should do to get this working properly?
thank you very much for all your help.

Custom ROM is your choice. There are a lot of JB ROMS that are pretty stable. Also a new stock JB leak in the dev section. As far as backing up your imei. You'll need to root first as soon as you do get a file explorer and copy the whole EFS folder to your external SDcard. Then also copy it to your computer. The imei is held within the EFS folder. From now on do this as soon as you root BEFORE you flash anything. lol

Thank you very much! I'll start rooting now and back it up immediately. I would love to give her a JB rom, mainly for google now. However, that radio is for ICS. Is that going to cause a problem? or will it even work on JB?
I've been on JB for months using an ICS radio. I'm on ATT so I can't say for certain but it shouldn't be an issue. Just go to the DEV thread and spend a few hours reading up on what's available. Like I said most of the ROMs are pretty stable at this point.
FYI, on skyrocket the IMEI is stored in mmcblk0p18 and mmcblk0p19, not /efs partition. Might really want to back those up, especially before attempting a usb unlock. The /efs only really stores exports of certain properties from mmcblk0p18.

Thanks for the heads up. lol I thought for sure they'd be stored in the same place they where for my SGS4G. So what is stored in the imei folder in EFS then?
i tried to unlock the note 5 i have using nv_data.bin without making a backup of my efs. got all the way through installing twrp, custom darkstar rom, and more. When i went to finally put a working sim card in it.... NO SIGNAL/BASEBAND UNKNOWN/IMEI UNKNOWN! i tried everything, from using smart switch, to odin.... Whole firmware flashing, to just modem.bin & sboot.bin (and others individually) for a while seperately it wouldn't work with a full firmware restore (using odin or z3x it would stop at cm.bin) but eventually i got it flashed and back to stock with odin & z3x on N920TUVU4DPK6 latest firmware, even used smart switch to flash to stock, but NOTHING brings back the imei or baseband. even tried to use xposed to change imei with app when it was showing up missing. efs backup pro didnt work as it couldnt read pit for some reason but odin could read pit just fine. z3x wont reset efs, wont repair, wont repair certificate, wont unlock. even the efs backup pro apk wont fix the problem.
Im all out of options... i am very knowledgeable about technology in general, and i have been rooting/flashing/tinkering with android phones for 4-5 years now (working with computers and tech for 15 years). Im stumped on this one... anyone who has some extensive knowledge in this department willing to connect with a team viewer session and try to help me out or at least post somethings to try.
I really need help BAD and am lost without guidance... i also can't afford to buy a new phone so im hoping this can work again soon. before i did anything it was working fine, only locked to t-mobile so i dont think its a hardware issue.
anyone out there got a heart (and brain lol) to help! :crying:

Do you have efs backup ? If you have made efs backup i can help you. If you don't have efs backup then i suggest you go to any repair center cuz odin or custom recovery not gonna do the job.
To restore efs/imei you will require a dongle box to write new cert files in efs partition.

I have the EXACT SAME problem that you have. I'm on the latest firmware N920TTMB4DPH2, I can't rollback to prior firmware. z3x couldn't detect my phone's modem, I've been looking for a solution too. In my case, someone told me (even z3x log said the same thing) that I have to downgrade the phone's modem, but I still couldn't find a way to do this. I think in my case, I have to wait for Samsung tool Pro to finally support the modem or find a way to downgrade the modem. (Can't even find any modem out there). I just tried Samsung tool Pro 27.4 today, still doesn't work. I think you might have seen this post? This might help?

I really need help BAD and am lost without guidance... i also can't afford to buy a new phone so im hoping this can work again soon. before i did anything it was working fine, only locked to t-mobile so i dont think its a hardware issue.
anyone out there got a heart (and brain lol) to help! :crying:

Do you still have the nv data bin file?

i tried to unlock the note 5 i have using nv_data.bin without making a backup of my efs. got all the way through installing twrp, custom darkstar rom, and more. When i went to finally put a working sim card in it.... NO SIGNAL/BASEBAND UNKNOWN/IMEI UNKNOWN! i tried everything, from using smart switch, to odin.... Whole firmware flashing, to just modem.bin & sboot.bin (and others individually) for a while seperately it wouldn't work with a full firmware restore (using odin or z3x it would stop at cm.bin) but eventually i got it flashed and back to stock with odin & z3x on N920TUVU4DPK6 latest firmware, even used smart switch to flash to stock, but NOTHING brings back the imei or baseband. even tried to use xposed to change imei with app when it was showing up missing. efs backup pro didnt work as it couldnt read pit for some reason but odin could read pit just fine. z3x wont reset efs, wont repair, wont repair certificate, wont unlock. even the efs backup pro apk wont fix the problem.

what! add me on the list, i was searching the same problem, and i found this thread. i guess no one can help in this community with no backup efs file. my device is sm-n920t note 5. i can downgrade to lollipop by, from stock nougat i will root and flash custom firmware, then on the custom firmware i flash it to any stock rom. this doesn't solve the problem.
Haha same issue here... A year later... And still no solutions... Mine is SM-N920P. I accidentally rebuilt the nv_data.bin file and my unlocked phone is showing me that my SIM card is invalid. I'm busting my nuts to find a solution.
