S20FE rooted super weird problem - Samsung Galaxy S20 FE Questions & Answers

Hi, im kinda desperate cause i really dont know what to do , here is my issue:
I bought a second hand s20fe i didnt know but its rooted and i want to remove it
The problem is that i tried booting it to download mode removing the root and trying to flash a original samsung stock firmware from odin, but it keep getting a error. Well i realized that the phone original model is SM G780G
And that the software that it had , was the SM G780F
So i downloaded a software for the G780F and apparently it worked with odin
But i want the original G780G software... what can i do?

I'm pretty sure your problem is:
you want to install a system with wrong binary.
Go into download mode and see what binary you have.
After you are sure which binary has downloaded the system you need and that's it.
if you have binary 3
upgrade to binary 3
If you can show a photo of what binary you have to observe.

Binario 1

I would like to tell you the full problem tho if you are so kind to give me a hand. I bought the s20fe second hand and it was rooted with a patched imei (the box and the software imei didnt match), i checked both imei and they are not blocked , so the phone isnt stolen. But here is the thing, the model in the box says 780G, and this software is 780F, the soft and the imei doesnt match. I tried rooting and unrooting, but now i dont have signal and i still have the same imei and software version, i would like to switch to the original imei cause im sure im able to use it , as well i would like to install the proper software version.

the equipment is not G780G.
1.G780G goes up to binary 4
2.G781B arrives
up to binary 5
3.G781U /U1 /V / N / W . go up to binary A(10)
4.G780F reaches binary A(10)
your equipment is a G780F and not a G780G. You can never load a system from another team, only from your variant.
Download an example system:
G780FXXUAFWB6
Currently there is the binary B(11).
luck.

unfortunately
it was advisable to leave it as it was when buying it.
if everything worked fine, there was no need to update.
just leave it with the system that was already installed.
since to change the imei, chimeratools, z3x is used. etc
They are paid applications and experience is required for it.
I used the z3x, that's why I'm telling you.

I dont understand, cause the model is in the back of the phone...

It didnt worked fine tho, i had a very low signal, now that i made a mess of course i would love to be back, but i dont know how to install a signal patch and i doubt that samsung would help me if im out of warranty, so i basically lost half of my saves on a phone that i can barely use now... what a luck

Personally, it is impossible to install an exynos system on a snapdragon.
It's like putting the engine from one car to another, just like that.
the cover says one thing, your phone another.
the caps are interchangeable.
Those can be put from an s20 fe exynos to a snapdragon.
check well.
personally you have a G780F.

try not to upload to binary B(11)
you will have to pay to solve the problem.
install software that it had initially, if the system was binary 9, it will be impossible.

the interchangeable cap make sense and also solve the imei trouble, i will choose to believe in your experience. But logically, then the email should be the one that is on the software right? and not in the cap? i already installed that version you told me, but how can i restore the signal? i just need to restore that and i will be able to sleep cause ive been awake almost 10 hours trying to figure out this mess

I really don't know if you can fix it.
I think your equipment was only rooted. The signal always worked.
I never touched the imei of your equipment.
It may even be that you are presenting a software error. once going to binary B. you will not be able to return to binary A.
if the problem does not recover without any update. It could be a problem with the internal antennas.
that they are disconnected.

I realized the problem, the case was switched indeed. And the original imei was changed because it was blocked. Since i update to the most recent binary and there is no chance to downgrade that, i wont be able to use sim cards anymore or at least until there is a new versión for patching the signal. I dont know which program the technicians use so i dont know if im ever going to recover the phone. An awful purchase and a even better movement from my part trying to update the android and removing the root. Im just disappointed, i hope this thread helps someone to not make the same mistakes...

At this point i dont even mind to pay for a signal patch, but there isnt a update for the system they use to do it. If someone knows anything about it, would be pretty helpful.

I understand what you're saying:
As a technician I understand.
Always before making changes, you have to know what we are getting into.
If you already knew that the imei was repaired and patched, for nothing in the world to update.
as advice, do not upgrade to binary B
stay in binary A.
The solution will come out, it always comes out for computers with an unlockable bootloader.
stay on february patch one ui 5.1 with binary A.
The rest are security updates.
Before listening to me, check that the system does not contain bugs.
in the best of cases, repair and sell, buy a G780G or G781B
luck.

Struggling with Cappy. Help Please.

Hi, all XDA users.
I've been waiting to post my problems here and tried a few things I could to fix then with no success.
Here's what happened.
I bought a Captivate in february in an eletronics store in Miami, and since I am from Brazil, at the time my only concern was to make sure the device was unlocked, so I tested my sim card and was OK.
So my problems started as I went back to my country, the phone works good, but some issues appeared and they are kind of major for a device like that. Here they are:
I can't download from the market ever since I bought the phone. From a wifi conection or 3G . That was disturbing me so I did the factory reset and that allowed me to use the market for a while, something like 10 minutes maybe, before started giving me the "download was unsuccessful" error. And I did the factory reset a few times . But that was only a taste .
I also can't update my phone from the 2.1 eclair to 2.2 froyo or whatever is available, through Mini Kies, always getting the "unregistered device" message, before anyone asks I tried that in a Win XP and a Win 7 64 .
I tried to do the update several times but I was never able to enter download mode on the phone.
I installed some apps using the Sideload Wonder Machine, since I wasn't able to do it using SDK tools . Perhaps because of the Win 7 64?
So I decided to leave the IPhone for this device for its greater hardware capacity and because of the Android OS overall improvement, but I can't do much with it now, and since I am totally noob, I don't really know if my device was rooted before I bought, I don't know If the best thing to do is to flash stock and start over.
Didn't flash because I am afraid of bricking it.
The one thing I know is that I was able to get rid of all the crap from AT&T and nothing changed in my phone, and I heard that I needed to be rooted to be able to do what I did.!?! Is that true? Please help.
Here are some info about my phone.
Firmware version: 2.1 update 1
Kernel version : 2.6.29
Samsung SGH-I897
Baseband Version : I897UCJF6
Thanks all for your time .
Kies Mini is for US updates. Did you try the full version of Kies? Might work for you there.

Will flashing a new modem help? Did you check network settings? Call company and switch to that region. I don't know. Just some suggestions.

Download one click odin flash the stock jf6 and master clear.this will do a full factory reset.

I did try the full version, but I will do it again in a XP version of windows and tell what happens .
I am downloading it from the brazilian samsung domain (.com.br) .
I tried again to use the regular Kies but didn't work.
It kept saying my device is not supported .
Funny thing is that in the Kies website, as you change the country flag in the bottom of the screen, the supported devices also changes, and in Brazil there is only a "Wave" called line of devices, while seems that the cappy I can only find in Canada. My point is that the Captivate IS supported.
I had a similar problem when a bad ROM flash borked my IMEI and product code. Chances are good that whoever unlocked your phone ended up screwing this up. Check out this guide to restore a specific IMEI to the device.
Also, you won't find the Captivate supported outside of the US or Canada, since it is only sold under that name by a few specific carriers (in the US, only AT&T carries it). Outside the US, Samsung mostly pushes other Galaxy S phones. Still the same "family" of phones, but there are differences between them.

Thank you so much. When I first had the problem I figured this was one possibilitie, but the salesguy assured the phone was "factory unlocked", so no one could've laid their hands on the device to screw it up like that. Your info was very valious, I will try to do the restore and let you know.

[Q] Updating AT&T S4 Active to Android 4.3+

Hello,
in my company we are developing an android app. The lowest android version this app supports is android 4.3.
The company bought several testing devices including a AT&T branded Samsung Galaxy S4 Active. With Android 4.2.2 (Buid Number: JDQ39.I9295UCUAMF3)
I tried it for a while now, but I can't get the OTA Update to work. It says "Software update interrupted. Try again in 24 hours".
I can bypass the 24h lock by changing the date of the phone. But even after ~30 tries the phone is not updating.
There is no SIM Card in the phone. Is a AT&T SIM Card needed to update the device? I am not able to get one, because I am located in Germany.
Can I update the phone manually with Kies or something?
I don't have admin right on my machine so I need to know what to do, before I contact the admin to install a required software.
Could a blocked port be an issue? I do have access to the internet, but if Samsung (or AT&T) uses some non standard port, my company could be blocking it.
(Root is not an option.)
Kind regards
Cliff

Hi Cliff. I can't say for sure, but my guess is you can't access the OTA because you're not in the right region (someone correct me if I'm wrong). As far as I know, you shouldn't need a SIM to update, again could be wrong. More importantly, there are other ways to update. You could probably try Kies, but I wouldn't recommend it, it seems like users always have issues with Kies. I would strongly recommend you try updating the phone with Odin, a tool by Samsung that let's you change around your phone's firmware (among other things) when the phone is in download mode.
There is an exhaustive guide linked to here that thoroughly explains how to go from any version of android (official, for this phone) to any other version. In simpler terms, that link shows you how to manually update, which is what I think you're looking for. Also the files you'll need to download are located here. Hope I've helped, and good luck updating! :good:
Oh, just re-read your caveats: you almost certainly don't need a SIM for Odin to work, and you definitely don't need root either.

Thank you for your answer. Yes, maybe AT&T does region lock the update -.-
I've used Odin on my old Galaxy S2 some years ago.
I'll have a look into it and decide if this is the way to go.
Odin will do it as long as there are full install files for you to use.

You need an AT&T SIM card in the phone in order to install AT&T OTA updates. You can't use Kies to update because AT&T won't let Samsung post AT&T firmware on Kies. So your only option is to use Odin and the guide posted above.

G920A Combination File to Recover IMEI?

Hi all,
I live in Australia. The battery on my S6 was replaced recently. Now the IMEI number shows with around 10 "0's" in the middle of it, and it can't connect to a network.
Apparently, according to this thread, I must flash the combination file, then flash the stock firmware, to retrieve the IMEI number in the phone and fix the issue.
However, the stock firmware has to be the same or earlier than the combination file, otherwise the device is bricked. I am yet to find a combination file that matches a stock firmware so I can actually do this.
Has anyone got a recent-ish combination file for the G920A? And if so, it would be great if I could have it, as long as I end up finding a matching stock firmware for it.

What baseband version does the device currently have? (if you don't know, it usually looks like G920AUXXXXXXX)
Don't worry, I paid $10 for the file on a website, tried it, but it didn't resolve my problem. The next solution may have worked, but it required root, which I was unable to do with my ATT Galaxy S6 locked bootloader.
Sold it though as a 'wifi-only' device.

Question IMEI gone

Hi guys, I'm in a very big trouble, since I was trying to rollback yesterday from A13 Oxygen 13, in a converted NE2110 Chinese model flashed previously with NE2115 Rom, I was having ridiculous battery life with the rom, so I want to test the European NE2113 rom, I've download the NE2113 Rollback package and applied with the local update apk provided by Oneplus, the procedure was apparently sucessfull, but SIM isn't recognized when A12 NE2113 rom booted, I've thought its a band relates problem, so I've flashed black the NE2115, but stills the same, I've get in to the IMEI numbers, and both are NULL and Baseband is blank.
I'm in Ecuador so it's absolutely impossible for me to sent the phone to Oneplus Repair services, and even if it was possible I doubt a lot they can take the phone, because it's bootloader unlocked.
If anyone have an idea about something I can do, I'll really appreciate that, it's an expensive phone and I've put a lot of effort to buy one trought and auction sale and even played to import from United States, so if you think there any hope available please share with me, I've read the one post here with someone who still needs to repair the IMEI seeing it's impossible for now, but at least I have to try to restore the phone, I can't have a media player unusable SIM phone of almost 700 bucks.

S20FE Not Updating since OneUi 3 and Android 11

Hello all.
My S20FE (SM-G780F) has not updated from OneUi 3 and Android 11. It always says that I'm using the latest software. I've tried factory resetting the phone and using Smart Switch to no avail.
I'm in the UK. Never lived anywhere else. I reside here permanently. It's where I bought my phone brand new.
I checked the service provider software version and it says ZT0/ZTO,ZTO/EUX . However, when I use the dialler method to check the same information it says the CSC is BTL3.
I researched and ZTO seems to refer to Brazil. I've never been to Brazil or anywhere in that vicinity so I don't know why it says ZTO as the service provider information.
Could this be why I'm having issues updating? If the phone thinks it's Brazilian then it would stop me updating if I'm in the UK? Is that correct?
Samsung suggested I send it to them to flash the drive but they require a proof of purchase and as I bought the phone over 2 years ago I can't for the life of me find the original order email.
Just for clarification the phone has never been rooted or modded and all software etc is "official." I've looked into flashing the software with Odin. Would I need ro download the update file for the CSC my phone says it is or for the CSC it should be? Do I only download the latest update or would I have to stack them and download all the previous ones my phone missed too?
Please help before I tear my hair out.
flashing the phone yourself with Odin is very easy, there are dozens of YouTube vids to get an idea from. actually downloading the firmware is more difficult.
whoever sold you the phone is who you should be angry at, it obviously wasn't intended for use here. let me know if you want help flashing!
Same thing happened to my Mom's phone (a Galaxy A series device).
Use this guide and manually flash the latest firmware.
