[ODIN][UCLB3] UCLB3 Unbrick - Return to stock - Working PIT included

ABOUT
-------------------
This is a package to return your Infuse 4G to a complete stock state with the AT&T UCLB3 Gingerbread release. It includes a PIT file to repartition your phone. Also, this resets the Custom Binary Download counter. Consider this a way to put the phone back to stock or to recover from a soft-brick without going all the way back to Froyo.
There is both a complete stock version and a rooted version below.
PACKAGES
-------------------
Stock UCLB3
UCLB3_Unbrick_1.1.zip
Stock UCLB3 with root
UCLB3_Unbrick_root_1.1.zip
The version with root works exactly like the above version, but adds root. To add CWM recovery to the rooted version, download a custom Gingerbread kernel from HERE or HERE and flash the zImage using SGS Kernel Flasher (found in the Play Store) on the phone. If you go this route for root and CWM, your Custom Binary Download counter will not show any custom binary activity.
INSTALL
-------------------
1.) Download and extract the zip package.
2.) Place phone in download mode.
3.) If needed, install latest Samsung USB drivers by installing Samsung Kies from HERE.
4.) Open the included Odin exe.
5.) If phone is detected, the window under ID:COM will turn yellow.
6.) Click on "PIT" to browse to and select infuse_gb.pit. Make sure that Re-Partition is selected.
7.) Click on "PDA" to browse to and select PDA_UCLB3.tar.md5.
8.) Click on "PHONE" to browse to and select PHONE_UCLB3.tar.md5.
9.) Click on "Start", and allow Odin to flash the phone. Do not unplug or power off the phone until Odin is finished.
10.) When the Odin dialogue reads "PASS!", the phone should reboot into the stock UCLB3 Setup Wizard.
FAQ
-------------------
1.) Should I do a software Factory Reset in settings after flashing this?
In the case that the Setup Wizard does not appear on the first boot, apps from a previous installation are still present, or you have other issues, go to Settings / Privacy and choose "Factory data reset" and then "Reset phone". This will ensure that the phone is completely reset, and that there is nothing left-over from a previous install to cause issues.
2.) I have rainbow distortion in recovery or in the boot animation. How can I get Gingerbread bootloaders to fix this?:
If you have rainbow distortion, you still have Froyo bootloaders. You can download THIS .rar file, extract using 7zip, and flash the tar.md5 package in Odin (use the pda slot). Flashing Gingerbread bootloaders will correct rainbow distortion in recovery and in the boot animation. Only flash these if you are having issues with rainbow distortion, and only if you have had success flashing other, less dangerous items in Odin.
3.) Does this package remove anything from the internal or external sdcard partitions?
This package does not remove anything from your internal or external sdcard partitions, so all of your user files stay on the phone. If you are using this to reset your phone to stock before selling it, etc., you should format personal storage by using options found under Settings / SD card and phone storage.

CHANGELOG
-----------------
6/13/2012 - v. 1.1:
Fixed a bug in the initial version of the UCLB3 Unbrick that caused the phone to lose APN settings. After flashing the new version of the UCLB3 Unbrick, the phone now reboots into the Setup Wizard and does not have APN issues. Thank you to hvega11 for the heads up on the bug.
The new version is in a zip archive called UCLB3_Unbrick_1.1.zip and contains a README.txt file with this changelog information. If the zip archive README.txt does not contain this changelog, then you are using the older version. It is suggested that you delete that version and download version 1.1.
If you downloaded and used the initial version, you might have lost APN and carrier settings immediately after flashing. Go to Settings / Privacy and do a factory reset. This will set you back to normal. The new version should not normally require a factory reset after flashing, but a factory reset in settings is suggested if you have any issues.

Nice job, JScott.
You da Odin Man!

Wow, Scott you are "working it" these past weeks, Thank You Sir for your work.
Added to ISET page..thx again

EDIT: This bug has been fixed, thanks hvega11 for the heads up!

Also, are you on AT&T or something else?
EDIT: Now that I'm on the PC, I can see that you are with AT&T. You can't see all of that in Tapatalk.

att theres just signal bars no att logo no h icon then in settings when you click apn its empty the click on network operators and its grayed out you cant add or change anything at this point

Alright, have you tried doing a factory reset in Settings / Privacy? I'm also going to test again here. Let me know what you get after factory reset, though.
EDIT: Just got finished with another test. I got the exact same behavior. After flashing the UCLB3 Unbrick, the phone had no APN settings or carrier information. After doing a factory reset in Settings / Privacy, all is back to normal. Do that if you haven't, and you'll be good to go.
Thanks for the heads up. I'm taking the file down until we get better results without having to do a factory reset in settings. I think that I know what is causing this.

What do you think is causing this?
Occasionally, I also noted that a factory reset is also needed to clear out all other data. I did not noted the APN problem though.

Since the PIT file repartitions the phone, the unbrick package has to have a dbdata.rfs file to rewrite that partition. Of course, neither this or the PIT file were included with the Przekret UCLB3 leak, so I dumped both from the phone, and edited the PIT file in a hex editor to remove several extra lines. The PIT file is good to go; I'm pretty sure that the issue lies in when I dumped the dbdata.rfs file from my phone. I live on the side of a mountain, and have very poor reception. I'm going to try to keep my personal settings and environment out of the mix when I dump the dbdata.rfs file. I'm trying a few things, but will let you know for sure after I test a theory.

Thanks jscott for the quick response sorry trying to do a factory reset didn't even cross my mind lol I had already odined back so I didn't get to try it.

Thanks again hvega11 for giving us a heads up about the APN issue / bug in the first version of the UCLB3 Unbrick.
The UCLB3 Unbrick is fixed and good to go. It was the dbdata.rfs file. I needed to dump it right after clearing cache and data (factory reset), and with the phone on the Setup Wizard screen. The tricky part was still having adb access at that point with USB debugging enabled. I remembered that you can wipe data and cache in CWM recovery and still keep USB debugging enabled, so I did that. At reboot, as soon as I saw the Setup Wizard, I got an adb shell and dumped the necessary files.
The phone starts at the Setup Wizard now after using the UCLB3 Unbrick, and doesn't have any APN issues.
EDIT: Version 1.1 has been uploaded. The APN bug has been fixed. This is working 100% for me. I've tested it over and over, and tried many different scenarios coming from ICS and Gingerbread roms. Every time I get a 100% working stock phone at the UCLB3 Setup Wizard.
EDIT 2: The only time that users might have to do a Factory Reset in settings is in the case that apps from a previous install are still present, or if any other issues arise - just to be sure that nothing is left-over from a previous installation. In most cases, the user won't have to do a Factory Reset in settings.
I need as many people as possible to test this and report back that it works. Thanks!

glad you got it fixed ill try it out tonight and report back

I've found that I personally prefer having an unbrick option that has root. So, I've updated the OP with a rooted UCLB3 Unbrick.
To get to CWM recovery from the rooted version: Flash any suitable custom Gingerbread kernel by using SGS Kernel Flasher. Then, it's back to flash, flash, flash, flash, flash, oops, unbrick, flash, flash, flash...
Neat thing is, that by not using download mode to install a custom kernel, the Custom Binary Download counter doesn't show any custom binary activity.

Stuck on boot on Samsung logo (after using dr fone)

Hi guys,
i wonder you can help.
I used a software called dr fone to try and recover some messages from kik.
It was running and then it rebooted my S7, but then it was stuck at the samsung logo. I left it for a while and nothing was happening so I unplugged it and tried to restart. but now it always just boots to the samsung logo with a flashing notification light.
I've wiped the cache and that didn't help.
Does anyone know how I can solve this issue? Preferably, obviously, I want to keep all my data but if not then there's nothing I can do.
Will a factory reset do anything?
Can I flash a custom rom without root? And without unlocking bootloader? (I've no idea if the bootloader is unlocked or not)
Can I flash a Rom with odin(?) that will fix the device and keep the data?
Help please!
And a word of advice. Never ever use Dr Fone!

Flash stock over the top with ODIN 3.12.3 or newer, use HOME_CSC instead of CSC to avoid factory reset

The stock firmware comes as 4 separate files you need to flash at the same time, there are two choices for CSC as above
CSC = Factory reset
HOME_CSC = No reset
Only choose one
Flash the stock ROM for your model S7, and your region / carrier
updato.com is probably the best place to find it, or the samfirm tool here on XDA

OK, I've downloaded ODIN3 v3.1.2.3, the One Click Root version.
I'm currently downloading the stock firmware from updato.com, it's 2.1 GB in size, does that sound right? And it's going to take over 2 hours to download!
I can't see the options for HOME_CSC and CSC yet in odin, maybe I'm come across that later in the process?
I'm just waiting now foe the download, but once the stock firmware is finally downloaded, do I just boot up the S7 using Vol Down + Home + Power to get to the Download Mode. I press Vol up to select continue and then ...

You need ODIN 3.12.3 or newer, unless that is a typo that is too old
Here is 3.12.7
Code:
https://mega.nz/#!jUgRiTSa!fnAVwr7yFi4dlPk4V0oQ5DuoFe3iiG0jH-ws91IHOPc
Yep, enter download mode, connect phone to PC USB, make sure the COM port is highlighted at the top of ODIN, then load the 4 firmware sections into ODIN
Hit start and wait for it to complete, you might find if that Dr Fone did more damage that you need to factory reset if the first try doesn't fix it
ODIN has the correct locations labelled for the specific parts of the ROM
BL
AP
CP
CSC
Each section of firmware is labelled accordingly, match them up

Thanks again!
It was a typo for ODIN but I think I downloaded the wrong version anyway as I don't think the one click root version is the right one? It's strange though, I went to https://odindownload.com site, which i thought was the official site and their latest version is 3.12.3? And you've linked me to 3.12.7. I don't have root but this version should still be OK?
I think I get the home.csc now. It's just a file from the stock firmware that I just select to go in the CSC box.
I'll just wait for the download now and I'll let you know how I get on. And thanks so much for all your help so far.

In case you're not here when I have finished the download, can you tell me if I have to change anything in the options in ODIN or leave as default? There's only "Auto Reboot" and "F. Reset Time" selected.
Also, at the moment, my phone is connected to my laptop but is turned off. The com box in odin is
0:[COM3] and is highlight a sort of bluey colour. Does that mean it's connected properly or does the phone need to be turned on for it to highlight to a different colour?
Thanks

It only matters that the COM port is highlighted when the phone is ON and connected, to show that ODIN can see the phone
But either way, pressing start and the phone responding is a sure way to know too

Right, Odin has finished.
It rebooted, took a little while to get past the samsung logo. Then sort of reached the home screen, but then it has crashed, become unresponsive. I can't get into the phone. Can't unlock it.
When it first reached the home screen, it said that
com.sec.epdg has stopped
ims service has stopped
and now it's just black screen, buttons don't appear to work also, when I first saw the home screen, a notification said that the "android is upgrading" with a progress bar.
Any ideas? Do i just wait?

Did you download the latest firmware? As in Nougat?
Possible if you downloaded an older version it would cause the crashing because newer apps and system apps vs older OS don't work well together
You could try booting into recovery and clearing CACHE
If that doesn't work and you definitely flashed the latest firmware, you might need to factory reset, but connect your phone to the PC while it is booted and see what you can recover via USB if it will let you
You could try safe mode too

Yeah, I downloaded latest version Nougat version from but looking at it again now, I just chose the first region in the list which was United Kingdom (BTU), but there are other versions, which i think are for different networks like VOD, VIR, but also XEU and H3G which I'm not sure what they are. Mine is unlocked so does it matter which one U chose? (I don't know what network, if any, it was locked to before).
Do you know which one I should choose or does it not make any difference?
I have cleared the cache and no change.

No it won't be due to that, BTU and XEU are the unbranded versions, the others will have carrier bloatware apps and branding on them
You could try flashing once more, but I think you're gonna end up having to reset unfortunately

If you already have BTU there's no point flashing XEU, I meant try flashing BTU again, I've once run into a problem that required me to flash the same stock ROM twice before it would boot correctly back in the Marshmallow days
Difference between XEU and BTU = when you receive OTA updates, nothing more
Moral of the story, always backup whatever is important, especially if you're about to mess about with something like Dr Fone

I'm going to try flashing them both a couple of times if need be before resorting to factory reset.
How would I do a factory reset? Would it be with just using the CSC file, rather then the HOME_CSC in ODIN?
My moral of the story is DO NOT USE DR FONE EVER! Dangerous, pathetic software.
Ironic that I tried to use this software to recover data, only for it to lose all my data!

Flashing the XEU firmware worked! I don't know whether it was the different versions or just flashing it again made the difference but I don't care. I lost some system settings and my keyboard but I think most of my data and apps are still there.

Unable to download older firmware

Hey guys, I really screwed up big time with my S7. My model is the SM-G930F. I have numbered my mistakes below so it is easier to follow.
1) I wanted to root my phone, so I followed the guide for HighonAndroid on youtube.
2) Fast forward, got TWRP and flashed Magisk root v16 and samsung anti-root removal 2.4.
3) Restarted phone and got this message along the lines of "integrity of phone has been damaged... please factory reset"
4) I advanced factory reset, and also accidentally ticked the software reset as well :crying:
5) Phone is bricked, and stuck in bootloading error. Cannot be turned off, it would just continue to recycle the Samsung S7 screen on repeat until put into TWRP mode...
6) Can only assess download mode and TWRP mode
If you are still following, this is where I am stuck ATM. I just want a working phone at this point...
7) Download official 7.0 nougat software for my phone model.
8) Odin the firmware over however the message stays stuck at this: https://imgur.com/a/UMQPw
9) Cry
If anybody can help that will be great, thanks!

Looks like Odin is not signing a com port to the phone.
Drivers are installed? Tried different usb cables and usb ports?

The phone stays connected, but the second I flash my phone just reboots.

You're not flashing BL, CP, and CSC?

I was under the impression S7 was beyond the time of using single tar/md5 files, you should have 4 separate files (BL, CP, CSC, AP). Where'd you get the firmware?
Try updato.com or sammobile.com, even the oldest S7 firmware I've downloaded still came with the 4 firmware files.

Yes I got the file from sammobile. I have tried flashing the 4 files however alas, it again just reboots my phone. I will follow up with an image when I get home and try it out again.

Still does not work. It continues to reboot. Tried different computers the phone will just reboot. Is there any hope left? I can access TWRP, meaning is it possible to restore/flash a backup from another user?

You can try Smart Switch which is the official method of a factory flash.
Otherwise for Odin if I recall correctly the latest firmware will chuck a fit if you aren't flashing the right firmware for your country, since the DRAG bootloader is meant to be more locked down.
You could also try different Odin versions maybe https://forum.xda-developers.com/showthread.php?t=2711451
You could try a stock ROM flash via zip like super stock or superman choosing clean install. Would be easier than trying to orchestrate a backup from someone.

Is there any errors that I have now seem consistent with anybody else's issue? Something like I might be flashing the wrong firmware into my phone, as a result the phone just reboots in download mode?
I have tried using both the new and old versions of odin and it still has the same result.
I am using the phone model SM-G930FZDAXSG

Really thanks a lot guys. Just having you guys readily available took a lot of stress off my chest. Someone cares
The issue has just been resolved! Yey. The problem was not running odin in administrator mode. As a result, my phone would just reboot instantaneously after flashing.

Question SIM/Baseband/IMEI errors since Tuesday 17th

I'm getting a problem where everytime I try to call someone or I receive a call, my SIM cards become undetected, the phone crashes after a short time and then doesn't detect SIM cards again, and Samsung or Google backups stop working, and all Samsung account related apps refuse to work. Only fixable after multiple factory resets.
After some investigation, I found that the Baseband and IMEI of the phone seem to be "unknown" whenever this occurs.
Is there a reason to this, or even a fix?

same with my A125F variant, try to reset your device and it will fix the problem
and don't update your device with the build number of A125FXXU1BUG6, i think there's is a bug with that update..

You were completely right! It WAS the new update. I flashed the previous firmware and my SIMs work perfectly now! I've turned off auto-update in the normal area and developer settings too, hopefully can avoid it till it's fixed sometime. Thanks again!

I found a way how to fix it... try to flash the A125FXXU1BUG6 firmware version together with the pit file and it will fixed the problem

Hi all,
That sounds exactly like the problem I have
When I ROOT, I unblock BOOTLOADER, the connection to the network is blocked.
When I ROOT, I unblock BOOTLOADER, the connection to the network is blocked: / Bootloader unlocked = connection blocking
forum.xda-developers.com
(I was assuming it was due to the unlocking)
I was using Frija to get the latest (bugged?!) version - I was unable to find the previous one
Baseband A125FXXU1BUE1 / Build A125FXXU1BUE3 (XSA)
Could anyone please describe where to get an older version / the pit file?
Thanks a lot for that!

is your device is A125F?

A125F pit file i used this pit to fix the problem
A12_EUR_OPEN
MediaFire is a simple to use free service that lets you put all your photos, documents, music, and video in a single place so you can access them anywhere and share them everywhere.

Thanks a lot, if I cannot find the lower firmware (it's on Samfrew, but downloading will take ages...), I'll give it a try. And good to have it if I get a bootloop!

i have an app that can download latest firmware for Samsung

or just try this website https://www.google.com/url?sa=t&sou...0QFnoECEIQAQ&usg=AOvVaw0neIA-O_nYmWom070upF4v

Just as a note for everyone who has the same problem -
I could fix this without the pit file, all that was required was flashing the complete (previous) firmware with Odin.
So not just the AP file but all the other ones as well (AP, BL, CP, CSC). Maybe a modem issue?

Hey guys, i tried everything, but have not been able to fix it.
I have the SM-A125W
and I tried flashing:
Samfw.com_SM-A125W_RWC_A125WVLU2AUFA_fac
Samfw.com_SM-A125W_RWC_A125WVLU2AUG5_fac
Samfw.com_SM-A125W_XAC_A125WVLU2AUFA_fac
Samfw.com_SM-A125W_XAC_A125WVLU2AUG5_fac
and used the pit file:
from: https://www.full-repair-firmware.com/p/galaxy-a12.html
and also, checked repartition option in odin,
When i make a phone call, and hang up, the sim card and phone number shows UNKNOWN
and when i perform a factory reset, it comes back and then goes again when i make a phone call.
Are we able to use the SP flash tool on this phone?
What seems to be the problem here?

I had this problem as well after updating firmware to A125FXXU1BUG6. I could not find a way to repair the IMEI until I found this file.
All I did was flash the tar file using odin in CP. I didn't need to flash other firmware packages or anything else.
Voilà!! Enjoy!

I've flashed the new A125FXXU1BUJ4 November security update and the bug is still there but I was able to flash the same IMEI/Baseband repair file and it worked. THANKS FOR THAT.

If you're not sure it a software fail, "Unknown" Baseband probably cause by faulty MT6177mv chip on mainboard. Usually damage by warter or falling, and it just need to reflow or replace a new one.both imei will re-apear when the baseband chip working.
Talking from personnal experient

Found my Galaxy Tab 2 - doesn't boot!

I haven't used my Tab 2 (P5110) in a long time. I rely on my phone quite a bit instead.
Recently, I've been doing a bit of IoT stuff and though the Tab would make an excellent remote controller.
When I boot it, it shows the Samsung logo and goes no further.
Is there anything I can do to recover it, please?
I can get it into Odin mode, but I can't remember what can be done from there.
Can someone just steer me to a refresher, please?

Use recovery and do factory reset

You can flash TWRP from Odin and flash Custom Rom

With apologies, if I knew what "use recovery" meant, I probably would have already done it.
Can you help, please?

I've downloaded twrp-2.8.5.0-p5110.tar.
The guide on the TWRP download site says I should install Odin and look for the "PDA tab or button". I have Odin 3.14.1 and the buttons are BL, AP, CP, CSC and USERDATA.
Elsewhere, here, I'm told to use AP. Is AP the correct / safe option?
Thanks.

Yes you can use AP, but why are you using too old recovery?.
New Version of TWRP is available and you should use that one

Interesting. First try the progress bar went to about 80% and I thought it was working. Then it failed.
Second try ... waited for ages then failed outright.
Any other thoughts, please?

Interesting.
I have a couple of suggestions
1) Try to place the tar file in a folder without any spaces in the name in it and try to flash it again
2) Try to download the latest TWRP tar file from here https://dl.twrp.me/espressowifi/ and flash it with Odin 3.14.1
If none of this work, then I have no idea

use the latest odin, (in the latest it is called ap instead of pda partition)
