Need Stock Firmware G900AUCU2AND3!!!

I need the Stock Firmware version G900AUCU2AND3 So that I can flash back to stock. In the thread return to stock it has the previous version G900AUCU1ANCE. I get a error when trying to odin back (SW REV CHECK FAIL : [about]Fused 2 > Binary 1). So I am not sure how its done but need someone who has it do a dump or how ever its done to get it in a way that it can be flashed either by odin or in recovery... Any help will be appreciated... Thanks

i will need this too, i have my phone on at&t next and after a year i can trade it in, but if its custom os and stuff i cant return it, so i will need this too if i want to return to stock so i can upgrade to a new phone next year.

Bump: This is needed very badly. As I imagine many people had to take that bloat ware update. If anyone that has this firm ware has a problem and needs to restore back to stock. They won't be able to use the one that's listed in on this forum as its the older one, and now that there is Root. Its very likely this will happen daily that people will need it. I don't know exactly what soft bricked my phone so it can happen to anyone. My phone was fine until a reboot. Please, please, please. I'm begging everyone that has it. I asked Samsung and they wouldn't help. Next maybe going to AT&T store and having warranty claim done. I don't really want to find the out come of that.

I need this very badly as well. I rooted my phone and then tried to alter my screen density via an app I found on Google Play. It requested root, I granted the permission and then when the phone rebooted it hung on "Samsung Galaxy S5" splash screen and will no go any further. ODIN will not allow me to flash G900AUCU1ANCE firmware since I did the OTA update. If anyone could post up their G900AUCU2AND3, I would appreciate it very much.

I estimate we will get @ least One to two of these per-day until we get the files. Since we now have Root. It may take a bit as At&t version don't seem to have much for devs. Or ones that care to really help.(I'll probably get reamed for this. Sorry for you that help and for your time) I contacted At&t they told me they could not help but I could send my phone in for warranty exchange. Its that or go to BestBuy and they can flash it back. I don't have a Bestbuy Nearby.

Guys, check that post. Shortydoggg found a temporary fix for any soft bricks. It's for extreme cases. My phone is fine (apart from some deleted stock apps) so I'll hold off until i get some more info but if you cant boot at all, his method should come in handy.

YUP, I did the AT&T update check and got it immediately afterwards. I instead of flashing every one separately and rebooting loaded the three files so minus the Bl file. I did not have the problems of having to reload APN this way.

A flash of the CSC file restores the APN after flashing the AP file, or flashing it together with the AP file, but it factory resets the phone. Flashing the AP file only is mostly for those who do not want a factory reset. But, a factory reset along with flashing only the AP file will indeed wipe the APN. I found all of that out through trial and error.

Same troubles here pcidiot!!!! soft bricked and nothing will load onto the phone. ODIN gives me the same kind of error as listed on the starting thread! I can get to recovery mode and Download (ODIN) mode on the phone but nothing wants to flash. Do we dump? Do we Erase Nand? CONFUSING!!! why is it so easy to bunk up a phone!

There should only be two boxes checked in odin thats f. reset time and auto reboot. Also Make sure you only check and load your firmware in the ap slot in odin. Now flash.

Yea I did thank you. Did it today and thanked the poster too.

Want to start over! Need help!
So I want to do whats written out in step 4 of shorttydogs thread but I don't want to mess up or brick my phone. My goal is to start over and go back to stock with bloatware and everything that is available on stock if I were to go AT&T and buy it today. Here is a little background on my phone. My phone is rooted and I do have safestrap (and busybox). I backed up everything on my microSD card. I also have the g900AUCU2AND3 firmware on my phone. In addition, I deleted some but not all AT&T bloatware, which I want back. Lastly, for some reason the "add call button" during my calls is missing and was replaced with a "record" button I think this was because of me playing around with xposed. I deleted xposed framework as well as wanam and tried everything to get the "add call button" back but I couldn't. Thus, I just want to go back to stock to fix all these issues. I just have a few questions before I proceed just to make sure I'm not doing anything wrong.
1) If I flash the AP, CP and CSC files will I achieve 100% stock with bloatware?
2) Will this return my "add call button"?
3) Is it as simple as just using odin 3.09 and flashing the AP, CP, and CSC files?
4) I also understand that this will take me back to G900AUCU1ANCE but will I be able to do an OTA do go to G900AUCU2AND3?
5) Is there anything else I need to know to prevent my phone from bricking!
Sorry for the long post but I am fairly new to this stuff and don't want mess anything up!

Can't unroot my s4

I need to return my s4 and I want to reset it to the system defaults and remove root access. My problem is that I think I messed up downloading TWRP recovery because ever since then I can't access recovery mode, it just goes to Odin mode/download mode. TWRP doesn't matter though, I don't need to recover anything in this phone I just want it to be reset. So I tried flashing stock rom through Odin but it takes a out 10 seconds then it says it's done and when my phone reboots absolutely nothing changed. I didn't download any custom roms so I would even be fine with just being able to take all my personal data off and factory reset it but I can't do that. Any help is appreciated!

Do you have the U.S./A.T.&T. model (SGH-i537) or the international model (SGH-i9295) and were you on kitkat or lollipop? And where did you get the stock file you were trying to flash through Odin?

I have the Verizon SCH-I545 (NK1) on 4.4.2. And I got it from the galaxy s4 root website link to customroms.net

Oops you're in the wrong forum, this forum is for a different phone. The forum for that phone can be found here. Since I don't have that phone (neither do most people on this forum, I'm guessing) I have never used that forum. However, a brief glimpse indicates this thread might have the solution you are looking for. If not, this other thread looks pretty useful too.
In the future, please make sure you're posting in the forum for the correct device.
Edit: It also sounds like you might have downloaded the wrong file(s)

Oops! I'm new to posting on the xda forums I apologize. Thank you for your help though!

How to Unlock/Root Your Galaxy SM-G920T 5.1.1 without Tripping the Knox

Hello Everyone,
Today we'll be unlocking the Samsung Galaxy SM-G920T 5.1.1 using the Z3X Samsung Tool or Octopus Box Samsung, which both required you to root your Galaxy S6 SM-G920T. I will guide throughout the steps to root your phone without tripping the knox counter, which will allow us to use one of the programs above. We will use the (sboot.bin) which allows their service centers to do flashing and repairs to the device without tripping the Knox counter. The modified bootloader also disables write protection on the device. Once you are done rooting and unlocking the Galaxy S6 SM-G920T, we will restore the official firmware 5.1.1. Don't worry, your phone is unlock permanently regardless of the times you restore the phone.
The steps to root your Samsung Galaxy SM-G920T 5.1.1
1. Install Samsung USB Drivers
2. Put the phone in download mode by: Power phone off then press and hold Volume down, home and power keys at same time until you see warning screen then let go and hit volume up one time.
3. Plug phone in and wait for drivers to install if necessary.
4. Download Odin
5. Download sboot.bin for Galaxy S6
6. Open odin and then you should now see phone’s modem port highlighted in blue.
7. Click on BL tab and select the correct sboot.bin that you downloaded above. Then click start.
8. When phone comes back on, power it off again and put into download mode.
9. Download UniBase_BOG8_v2
10. Open odin again and this time select AP tab and select UniBase_BOG_V2 file and click start.
11. You're Done!!!
When the phone turn on, it will be rooted. To verify that knox has not been tripped go back to download mode and it should still say KNOX WARRANTY: 0 (0X0000). Now you can go ahead and unlock your Samsung Galaxy SM-G920T 5.1.1 using the Z3X Samsung Tool or Octopus Box Samsung. The sboot.bin isn’t playing very well, causing issues with Calls and Fingerprint sensor, but it is only for the meantime until you restore your phone back to the stock firmware.
Restoring your Samsung Galaxy SM-G920T to the stock firmware 5.1.1
1. Download the SM-G920T stock firmware
2. Open and extract the firmware file, then you should get the a file in .tar.md5 format.
3. Put the phone in download mode by: Power phone off then press and hold Volume down, home and power keys at same time until you see warning screen then let go and hit volume up one time.
4. Open odin and then you should now see phone’s modem port highlighted in blue.
5. Click the AP button tab and select G920TUVU2COF6_G920TTMB2COF6_G920TUVU2COF6_HOME.tar.md5
6. Make sure Re-partition checkbox is NOT selected, under the Options tab. Click start and wait for it to finish completely.
7. Enjoy!!! The G920TUVU2COF6 Android 5.1.1 firmware on your Galaxy SM-G920T.
I hope this guide helps everyone who wants to unlock their Samsung Galaxy SM-G920T, but needs their phone rooted first temporarily.

I'm sure it works on the G920TUVU2COF8 build, but I'm not 100% sure. If anything, you can always go restore your phone through odin.

Any chance we could get links to the files you reference? Thank you in advance.

Yeah, I'm familiar with Google and the like. I just thought it may make things easier on people if there were links to the files since this was put together as a guide of sorts.
I ended up using the guide that noodlev1 posted since it came up frequently in the search for the needed files. I tried to post it earlier but I'm not cool enough to post links yet. I can confirm that I was able to root a bone stock sm-g920t without tripping knox.
As far as the sim unlock goes, still not able to successfully keep the sim unlock after a factory reset.

I honestly forget which baseband I was on. I spent all day flashing different builds to try to get the sim unlock to stick.

The latest Tmobile is COF8, regardless COF8 or COF6 build you can unlock it. The Steps are easy, You must root the phone, unlock using Z3X Samsung Tool or Octopus Box Samsung and then restore the phone back to the stock firmware. Regardless of how many times you restore or update, your phone will always be unlock. Now you can also flash to metro pcs, but you have to stay with the metro pcs after you unlock it with the code.

H811 unbrick help

Hi everyone,
Please forgive any n00b questions.
I got started with rooting / custom ROMs on a Nexus 4, and I didn't realize at the time that this made things really easy and I didn't need to learn very much about how everything worked. Fast forward to last week -- I decided, at long last, that I was tired of using stock MM on my T-Mo G4 / H811. How hard could it be? Probably not much different from playing on my old Nexus 4 right? Lol, maybe not.
So now 72 hours later, my phone is hard bricked and will not enter download mode. and I need some assistance, if anyone would be so kind.
I will try to recount what I did:
To start with, I was using a Mac, so I used Homebrew to install Android platform tools / ADB.
I decided I wanted to try out LineageOS so I went ahead and followed their very clear steps (on LOS wiki) to unlock the bootloader install TWRP. However, TWRP doesn't seem to have an official build for the G4(!) so I had to look up and use one of the betas from this post. Is this where I went off the rails already? [Of course, very stupidly I also failed to make a complete backup of anything before going on ahead. Rookie mistake.]
After unlocking bootloader and flashing my TWRP beta, I was able to boot into TWRP just fine. I followed the normal prescribed steps of doing a Wipe (normal TWRP defaults -- system, cache, etc.?) before flashing the latest LOS nightly (14.1-something) and also the nano-x64 variety of gapps. I rebooted and got stuck with the LOS boot animation. I let this go for 55 minutes, so I am pretty sure it was an actual bootloop, not just the 1st-time-startup and optimization going on.
I rebooted into TWRP and decided to try a different ROM to see if that was the issue. So I wiped again, flashed another ROM (I believe it was a flavor of AOKP 14.1.x), flashed gapps again, and gave it another try. Again got stuck with an endless bootloop (45 minutes).
Since this is my daily driver, I decided to go back to stock. Found this thread, downloaded the MM-debloated zip, pushed to phone, and again Wiped + Flashed. This time, when I hit reboot, my phone was immediately hard-bricked. No startup screen, no nothing. That was quite unexpected. Also, the first time I had ever HARD bricked a device that I was playing with. Yikes!
Since then, I got a hold of a PC, and have been trying to revive the device by flashing an image to the microSD and booting into Download mode, in the form of this thread or this one.
I did get this to work briefly yesterday, or at least I got to Download Mode / Firmware Update screen, and then attempted to run LGUP with the KDZ file. However I ran into an error at about 9%, and couldn't continue -- and then I had to give back my loaner PC for the day. I also noticed that the LG Mobile Support tool was recognizing my phone NOT as an H811 but as something like HX230 or ... whatever it was, it was definitely wrong. Which is worrisome.
Today I'm giving it another try but my phone will not enter Download Mode at all, nor respond in any other way. I'm curious if this is a battery issue? So I am simply charging it for the time being. I also re-formatted the microSD and re-flashed the single .img just to be safe, but still can't get a response out of the phone. On my PC's device manager it is showing up as the common Qualcomm 9008 that a lot of people seem to have seen. No recognition from LG Mobile Support tool, nor from LGUP.
So ... what now?
It's possible that once my battery gets some charge again, maybe I'll be able to enter DL mode. Let's hope so.
However, I am also totally in the dark about which software version I should be using. 20i? 20p? I have no idea what these refer to, and I did not make any prior notes to capture the state that my phone was in before this all began. So IF I get to DL mode I will definitely need further instruction on the CORRECT KDZ FILE to be flashing. Else I will just compound my problems.
ANY tips or suggestions will be appreciated! Thanks so much.

Should have verified being on 20o firmware
Upon further reading, quite obvious, at the top of this thread, I definitely should have followed the Prerequisite steps. I did NOT verify that I was on 20o firmware. "OR RISK BRICKING YOUR DEVICE" is right.
So I bricked my device, in exactly the way I was warned not to do, it seems.
Still, what's the next step? Any thoughts?

Ok what was the last KDZ file you flashed which had worked? 20o?
As you have hard bricked your device you can try the sdcard method again if it works flash 20o again (of it it was 20o).
If you flash a lower version you will hard brick again.
If the sdcard doesn't work anymore for you you can try to flash with QFIL but beware to use the right one. If you use the wrong one it will convert your device and believe me that's not what you want. I can share the good ones but unfortunately maybe on next week first.
Otherwise search on your own for 9008 unbrick but check the md5sum of the programmer!! Compare it with the Evil one mentioned in my ARB list here: http://tinyurl.com/antirollg4 and DO NOT USE THE EVIL one..

If you flash a lower version you will hard brick again.
If the sdcard doesn't work anymore for you you can try to flash with QFIL but beware to use the right one. If you use the wrong one it will convert your device and believe me that's not what you want. I can share the good ones but unfortunately maybe on next week first.
Otherwise search on your own for 9008 unbrick but check the md5sum of the programmer!! Compare it with the Evil one mentioned in my ARB list here: http://tinyurl.com/antirollg4 and DO NOT USE THE EVIL one..

Thanks very much for the guidance! The post that you linked to REALLY helps. Until now I really was not sure what 10n, 20i, 20o, etc. referred to, aside from just various software versions. Having a definition for anti-rollback and further links to explain, really helps! This gives me more information and I might be able to self-resolve from here. I will give it a shot.
As for your question ... unfortunately there was NO instance where I flashed a working KDZ file, and I didn't know (due to my past experience with my Nexus) that I needed to check the STOCK software version of my phone before beginning to play with ROMs. In other words, I have no idea if I was on 20i, 20o, 20p, etc. From what I understand, this makes things a lot more difficult
Having looked at the linked thread just a little bit, it appears that using a 20o KDZ is the best bet -- because I bricked my device using a 20i ROM so I expect it was due to violating the anti-rollback restriction.
I will look into it more closely and come back if I hit another brick wall. Thanks so much!

If anyone cares, here are the ending results of all this ...
#1 Be wary of anti-rollback restrictions before you flash anything to your G4. You WILL brick your phone!
I tried multiple rounds and multiple variations of all the MicroSD card methods that I could find. I could NOT succeed in unbricking my phone.
#2 Luckily ... I was able to convince LG that I was still technically under warranty!
Because I had the stock bootloop issue in May 2017, LG did an in-warranty repair for me, and replaced the motherboard. So last week, I simply told them "my phone is AGAIN unable to charge and will not power on, just like in May". Since it had only been 5-6 months since the first issue, they agreed to replace the motherboard again.
Moral of the story: you can definitely unbrick your phone by having LG replace the mobo XD XD
From here, I think I will just totally avoid doing any rooting or custom ROMs on my totally-stock G4 coming today in the mail. I will cross my fingers and hope we get OEM Nougat in the USA sometime in the next couple of months.
Thanks again for the help everyone!

Need help fixing my bootloop stuck s3 mini

The model is SM-G730V
and it is a verizon galaxy s3 mini (if anymore info is needed i can provide)
I dont know precisely how my phone ended up stuck in bootloop or what i did to cause it, it just shut off one day and when i rebooted it was seemingly done for. Tried for weeks and gave up, ive got a laptop now that im able to flash with, and judging by the fact it won't boot correctly i take it i need to flash new stock firmware entirely. Theres many downloads available for both odin and for the firmware i will need for my device, im hoping someone can point me in the direction of a safe virus free version of both as im not skilled in any of this and am worried about getting viruses. Anything will be appriciated
