This is my first post on here, but I've used these forums before to root my S3 and at one time my current S4. My problem is with MF3... I used
this post [http://forum.xda-developers.com/showthread.php?t=2387577] to root my phone once, but since I couldn't install TWRP or CWM, I thought I could downgrade the software version with Odin. Well, I was wrong, and I unrooted my phone in the process... Upon trying the same technique I mentioned earlier, it now says "permission denied" upon entering the first prompt <<cd /mnt/extSdCard>>
AND, I can't use Odin to factory reset. Using posts such as this [http://www.youtube.com/watch?v=hZTTTk7vbVM] doesn't seem to work either. When putting my phone into download mode, I pull up Odin, and select the file in the link (the software file .tar I think), it says it fails shortly after starting.
Really, I need help with two things:
1. Obtaining root access
2. Resetting phone to factory settings
I might not have to do a factory reset, but I've noticed my wifi will NOT enable since I unrooted and this is a big concern for me. I know that all my troubles are because the bootloader is locked (and I'm messing with stuff I don't fully understand...), which is why I'd like help obtaining root again in the final hope that Safestrap [http://forum.xda-developers.com/showthread.php?t=2448925] is the answer I'm looking for so I can use my favorite ROM, LiquidSmooth!
PLEASE help me any way you can! I've tried to provide as much information as I can think of, but I'm new to this stuff, so bear with me. I have no real experience in rooting and whatnot, but so far, I've followed directions by users of this forum, so I have faith that there's a solution to this mayhem. Thanks for any help you can provide! =)
Your first mistake was not reading about what you can and can not do while on mf3. Your second was trying to put a recovery on. And your third was trying to use Odin to down grade your firmware.
I'm surprised your not having issues booting. The only way right now to get your phone back to normal is to see if best buy will flash the mf3 firmware for you

I guess you're trying to be helpful, but your condescending tone isn't helping. I READ everything, I just don't UNDERSTAND everything... The second paragraph actually provided some help, so thanks for that. I was just hoping for something I could do myself to re obtain root so that I can try the Safestrap method I provided in my original post. I will post a reply to the root method post and see if anyone can help me there, since that's my main issue is not being able to get root access back. I don't have any problems booting though, only when I boot into recovery mode do I get a loop in which I just have to get to the Samsung warning screen and select "cancel (reboot phone)". Thanks for reading this and providing some direction.

No, your main issue is that you don't understand what you are reading and you shouldn't be doing anything to your phone until you do. Dozens of people just like you pass through this forum everyday with similar issues because they didn't read or take the time to understand what it was that they did read. Someone takes the time to tell them to read and learn and they don't listen or think they don't have to. Then, they screw their phones up and come back here crying for help. So it's not a condescending tone, it's people getting tired of the same crap. You admitted that you didn't understand everything you read so why would you do anything to your phone before you do understand it? Can you not see the problem?
I've looked everywhere for every solution but I can't find exactly what I'm looking for. All I want to do is update a stock rooted 6.0.1 with TWRP recovery to 6.0.1 I don't want a custom rom but I dont have access to a pc at the moment for adb... Every flashable stock rom on here says I'll need to update things before flashing them using adb (like bootloader radio vendor etc). Well I don't see the point of a flashable stock rom that still requires adb ( I might as well update the damn thing completely by adb at that point). Is there any solution to my problem? I just need a little guidance if someone could point me in the right direction I would appreciate it.

Nope, I don't see how it's possible to update to .1 without updating the bootloader at least, besides there isn't any major differences in the new version other than a lot of people complaining about LTE and the camera.
There may be a solution to your situation of I understand you correctly. What you can do if you have access to another phone with USB otg capabilities is a mobile adb Fatboy. Here in XDA search for "Fastboot without PC" and it explains the process. Download the image files and manually flash the bootloader, radio, and vender. Also you can grab the vender in zip form on the pure nexus ROM post. That should be good enough to do what you want. You don't need the whole image of the new release.
My question really comes down to why can't these things be combined into a single flashable zip? In years past with all my other Nexus phones when an update came out I typically could just download a rom flash it and be up to date, I have a computer and can update it no problem, which I've already done, but I'm just more or less agitated that I can't do this stuff on the go while I'm bored at work or on the ride home, etc.
I'll put the long story below..but spare those that don't want to read. The short is, I'm not able to ADB Sideload the OTA images as it always fails to verifiy signature at about 40-47%. I've searched many places and not found a fix. So I'm hoping the genuises here at XDA which I frequent can help.
The long story. I've flashed roms for many years. My current device was the Nexus 6p. Running XE Rom I think it was. Flashed an update all was well, but my sim card would not show up. I was on MetroPCS and remembered needing a different radio. Flashed that,still no sim. Decided I'd go back to Stock since those had been updated to 8 by now. Flashed the OTA and followed some steps by another thread on XDA, one of the last was locking the bootloader. I had not booted up so I didn't know if my system was working. My big mistake! I locked my bootloader and don't have a system to boot into so I can enable OEM Unlocking. So now I only have adb sideload, can't flash individual images through fastboot! I think it can be recovered but for some reason the signature verification issue keeps coming up no matter what cable or PC I use.
If anyone has any thoughts I'd love to hear them. I have since moved to a Hauwei Mate SE and am pretty pleased but will not be a flashing phone I don't think. I loved my 6p and it still had lot's of life for me. I hate to sell it for parts at this point.... Thanks for anyone willing to chime in.

First, if i understand right you tried to flash OTA over custom rom to return to stock?? To go to stock you must flash full system image, not OTA.
And second, why the hell did you lock the bootloader??...you dont lock the BL unless you are 100% stock..
I know i didnt help you much, but if your BL is locked, dont know how to help...maybe someone else know how to unlock it again
Meanwhile read this guide,it will help you to understand some things:

Oh believe me my head hit the wall for sure! I got careless and wasn't thinking straight. No reason to lock the boot loader except it was on a list of steps to get back to stock..and I guess it was late! doh.
There are lot's of posts/videos I've seen that should allow what I'm trying to do with sideload adb but mine keeps getting a signature verification error. Each new full version of a release 7.0 8.0 etc..has the entire rom, images etc. So your suppose to be able to flash those even though they are OTA updates... *shrug*
It's a blur what I did exactly in some areas. I at one point may have tried to flash the set of Stock IMG files as well. But for sure now all I'm left with is a locked phone with who knows what on it! Stock recovery...some form of 7.0.0 that has NYC as letters...that I can find NOWHERE! on any official releases...
Prob trash, I really want that night back..lol.
I cannot get a working frp bypass method for this, security updates are a pain, tried sim card tricks, flashes, I don't frp bypass very often, maybe a few times a year for friends, so I don't stay too current with everything, but I know a few simple things. Help me out here, what would be the correct route here? anyone know working frp bypass for pie 9.0 after the security patch that corrected using locked sim card and causing sim card to lock? cause those ways don't work.

I will have to look into this a bit more, if I remember correctly combination file I would just flash the AP with the combination file right? Can you point me in the right direction of where to locate a good place to download this combination file? I remember last time I flashed a non stock rom to it i ended up with some weird logo with spinning gears on it... idr exactly what it was but i just flashed it back after that. Sorry for being so noob at this, it def is something that interests me though, thank you for your time.

The spinning gears are the combination. You flash that factory reset. Then flash stock firmware again. I don't know where to locate one for yours

OKOKOK !! I retract my last statement, the one i flashed before was not an exact match i guess cause it never boot to settings, but I actually got it bypassed today, ty so much, I flashed another n950u then flashed it back but didn't work, then flashed combination, fed it some adb commands for frp unlock (not sure if it helped or not) flashed back (this time I flashed not only ap, but bootloader, cp, and csc... which was probably superfluous, but well meh...) and it ended up working this time. xD TY very much you guys are great.

Prob was the adb commands. Combo had adb enabled and frp can be bypassed of you got adb

Ok so you are saying definitely keep feeding the adb commands to the device after combination has booted in the future?? Shouldn't hurt the process to be extra sure you know? TY for your time and responses
Hello to all forum members. :highfive:
Recently I got into my hands the Samsung S4 SGH-I337 version of AT&T, at least I think so. The current version of Android on it is 5.0.1.
When I set the phone to recovery mode, I think I see the modem version: I337UCSGOK3. Correct me if this is not the modem version, but I am sharing it because I guess this information will be helpful to make alternative software installation.
I've already spent 7 days trying to change the software, reading one by one what I will find about such an update. I tried tons of instructions and they all didn't let me do upload/change somehow software nor even install TWRP.
Tried to upload TWRP (I think I found 6 different files) using different applications from the original Android system - Failed. ie. I used TWRP straight from the system, I also used Flashify. When I use this Flashify app I installed TWRP, but it didn't let my phone go into recovery mode, it just went straight to the download. For me it looks like there is something to not let flash/change this to TWRP.
I tried to upload TWRP via ODIN, it doesn't work, it crashes during installation with error messages.
I also tried to upload lineageos version lineageos.17.1.recovery.img via the normal recovery mode, but every time I try I get an error about the signature not matching.
I tried to upload the software by ADB, I have had connection, I was able to see the phone, but I can only use adb sideload recover.img command and although I tried different images and .zip files, unfortunately nothing works. I think I also get an error that the signature does not match.
Can I ask you for some hints, maybe some instructions that will really work. Many instructions were based on specific versions of the bootloader, is what I called the modem above maybe I named this wrong and this is the bootloader version? If so, does anyone know about the instructions for this version of the bootloader? It seems to me after my problems that it is strangely blocked. Maybe someone knows how to make it work. I would like to change the software to change the system language to Polish. Unfortunately, the apps: MoreLocale2 and Language Enabler and probably about 4 others from the play store are not working.
Of course, the phone is rooted with Kingoroot, the applications detect that there is root, after all, after selecting the Polish language, it does not work in the system.
I would like to change Androind 5.x to LineageOS, because there you can do much more and it works better, more efficiently and saves battery. And I will be able to change language defenetly.
this is not the first time when I do that things. I have changed the regular S4 jfltexx many times, this is not the slightest problem for me.
Summarizing:
1. I would like to change the language to Polish, if it doesn't work or it won't be possible, it's a waste of time or something else
2. I would like to unlock the bootloader and upload TWRP, it can be CWM if anyone knows it will work and has an instruction that I can test
3. Then I would like to upload lineageos.
I'd appreciate any hints to test these things above.

I read that it will be possible to upload TWRP, but if it is a special version of TWRP prepared for this phone. Will someone be so nice and tell me if something like this exists and if so, where can I find such TWRP for uploading via ODIN.
Thank yo all for your time spending to read this.:good:
PS: Dear Moderators if this thread is not in proper place please correct this. Thank you.
Those instructions are for another bootloader. Your bootloader is locked, which is why TWRP won't install. There is no way to unlock it or downgrade. You also can't boot AOSP based ROM like Lineage OS. What you can do is root the phone and install touch wiz based ROM like Golden eye ROM by using the flash fire app if you're on lollipop or safe strap recovery if you're on kit kat.

Big Thank You for your suggestion and answer on my question.:good:
Right now I have Lolipop installed on the phone so related to this above I can only install something with touchwiz. Hope it will let me to change language to the Polish.
Would you be able to point me some links to instruction, please. I try to find this on forum but failed (getting ROM for nintendo). At least links to the software so I can try using flashfire app. The best it will be instruction, as I have situation in which when I use this app phone want boot after. Maybe it was related to the software, which I shouldn't use or maybe I do this in not proper way.
For everything what I get I'm saying thank you. :highfive:
No problem, I help when I can. The flash fire app you can get from the Google play store I believe, but your phone might need a specific version like the Verizon S4 does I don't know. The touch wiz ROMs are in this forum under Android development, go there and you should see ROMs like golden eye which is a touch wiz based ROM.
Here's a link that might help you, but the S4 is an old phone so it's hard to find links and guides that aren't buried deep in the forum posts.

Let me check this and back with the details what is working.
Alright man, good luck! I may not be able to help much further though, as I now have a Galaxy S10 and my S4 is just my storage phone, but I can try if it's something I know.
