I'm new to this guys, so I'm going to make this long story as short as possible.
A couple of years ago. I bought an s7 (sm-g930fd)from a guy who goes to the university in my city. I'm assuming he was an international student by the phone model. The phone never worked as a phone, but got it cheap to play games on for my kids. The longest time the phone was fine. Until about a month ago it started crashing. So I decided to have a look and found it was on 6.1 firmware. I tried updating using the phones settings to no avail. So a few weeks back I started reading into it. After a bit of reading I decided it seems simple enough to upgrade the firmware to 8.0 (as my s8+ uses it and recently my girlfriends s7) so I might as well update it. This is where my troubles began lol.
I followed a tutorial posted (on the sammobile site where I got the 8.0 firmware). Upon following that tut, and adjusting the settings in developer mode (OEM-off) I was with a start screen that had the red frp text at the top. At that point there was no turning back. Had to flash with the new firmware to fix the frp notice.
The flash worked perfectly. Or so I thought. I started to process into getting the setting up of the phone and bam. The last google account I used on there no longer worked. So I tried all the accounts ever logged in to it. Google locked. I learned today that frp and google lock are one and the same lol.
Everything I've read up until this point says I cant bypass the frp. So I've read downgrade to 7.0. Problem is odin wont downgrade to the 7.0 firmware.
I have no clue at this point what my options are. I'd rather figure this out myself. There is a fellow on local kijiji who wants 20 bucks to bypass the google thing. I'd honestly rather not. Hence this thread
Help or ideas? Anyone?
And sorry if this post is in the wrong section.
So the phone is IMEI blocked and Google account locked. To downgrade to 7.0 you have to find firmware that is March 2018 (Binary 2 Rom) downgrade from 8.0 Oreo or newer that is on nougat. You still need to search up on youtube the bypass method for doing so.
IMEI part, you'll have to search around for that service.
PM me if you need help with what firmware you need to flash.
Its Google locked yes. Not too sure about the imei. I've never used this as a phone. The guy who sold it to me said it was a demo model and the sim tray didnt work.
I actually just had my girlfriend take it to a guy locally, who's doing it for me.

Hi
My OH has just bought herself a recon S5 in the UK.
But it seems to be a bit jumbled up. Sticker on the box said SM-G900A (American AT&T). Device info says it's an SM-G900F (Europe). We are in the UK. I'm believing the device info.
But it seems someone has flashed a Chinese or Korean version of the firmware on it? Factory reset starts in Korean or Chinese (I can't tell which) and the firmware version is G900FZHU1ANG1. It's KitKat 4.4.2.
She wants it up to date on Lollipop. Whatever that firmware version is, it doesn't want to OTA update to Lollipop.
So, I've downloaded the latest Lollipop BTU build for the 900F (BTU-G900FXXU1BOE5-20150601141257.zip - which I got from a link on here) and plan to flash it with Odin 3.10.6. As per instructions on sammobile. (and here, they're the same)
I've not flashed a ROM for a looooong time and I don't want to brick her phone (cos I'll have to buy the replacement!). So before I go any further, can someone quickly confirm I can just go ahead and jump straight from the current KitKat firmware to this Lollipop build? Don't want root or anything, just the latest, official, unbranded, firmware for it. Which is what I have as far as I can tell.
A simple Yes or No would be great.
Many thanks in advance.
First up ..... apologies. I didn't get any answers I suspect as this was too obvious a question.
I was in a hurry, so I signed up and asked quickly before I went out last night, hoping for just a yes/no. I should probably have posted this in the "Assist" forum anyway.
As it turns out, it doesn't matter. Further reading said I could flash it as it as is. So I tried. And it failed (didn't brick it, it barely got started, phone still works). Box sticker said 900A (AT&T - which is a horrible version as it turns out). Phone info said 900F (International - which would have been fine). Recovery mode though, also reported it as a 900A. Which is I think is why it failed very early trying to flash it with Odin. So it would appear it is a 900A version, which someone has managed to get a Chinese firmware onto somehow to hide it being an American version and sold it to a phone reclycling store in the UK. And it looks like they got away with it.
On that basis alone, I would be returning it. (It would never get auto-upadtes outside the USA, is hard to root, hard to update, and updates from AT&T are VERY slow and she wants stock, not CM or anything)
But it doesn't matter. It has a bigger fauly.
The blue LED on the top left stays on constantly. Even when the phone is powered down completely. Which is not right. Overnight last night, powered off, it lost almost 20% of it's battery. So it's fauly. It's going back.
Thankfully she bought it from a large, reputable, online store in the UK. So the return won't be a problem. Just hope the replacement isn't a dud as well!
Mods please move if this is in the wrong section, I tried posting in the VZW s8 forum , but since this is my 1st post it would not allow me to.....
So I recently switched carriers from VZW to Tmobile, swapped the sim card at the store and went about my day
Soon after I realized certain things didnt work, service seemed it wasnt to its full potential, no wifi calling, unable to update the OS because its unable to verify, and still had a bunch of VZW stuff on my phone
After searching how to reflash firmware on my phone I found a thread on here and a thread on reddit that seemed to be the 2 most popular guides
I am pretty new when it comes to this but I gave it my best shot, ive tried regular odin, prince modified odin, and phonlab version of odin, and I either get stuck in the connection phase, or it sayss failed device mismatch, or it freezes at 32%......
Also im not 100% sure which firmware im supposed to be uploading as certain links recommend something different.
All I want to do is take my VZW S8 and make it as if I have a Tmobile S8, I dont mind the factory T mobile bloatware and all that stuff, just want to be able to take advantage of the carrier specific features
My build number on my S8 is G950USQU1AQDE
If someone knows of a clear cut thread or video guide that they have used and it actually works please share
Thanks in advance guys
Hey guys, hope someone can help this idiot out here.
I have an s8+, purchased from Argos in the UK unlocked, using it with a 3 sim card.
Over the weekend I got the oreo update, let it run and then realised I no longer had wifi-calling (kind of a major thing in my house)
After a bit of googling I saw I wasn't the only one, so I decided to try and downgrade it to Noughat using Odin.
I managed to do it, kinda (yet still no wifi calling) but I can't seem to find the right poxy firmware for it! Each one I try has different things in the settings menu that wernt' there before or things that when you click the phone crashes completely.
I've tried just about every one listed on Sammobile and getting nowhere! Listed under Galaxy S8+ SM-G955F
Any help appreciated.
Self update.
Just flashed it with the 8.0 3 Branded Firmware.
Got my wifi calling back and the settings menus look about right!
Just need to get rid of all the 3 bloatware now tho
try the
https://forum.xda-developers.com/galaxy-s8/how-to/how-to-remove-oem-bloatware-s8-s8-t3654687
I cannot believe a phone this 'old' is so hard to find a successful root for; with the amount of bloatware that comes with it - its crazy.
If anyone can help me find a root method that still works for Android 7.0 on the Samsung Galaxy S7 930A
I WOULD REALLY APPRECIATE IT. Its bugging me I have been searching for 2 days now..
Until Samsung pulls their head out of their ass and unlocks the bootloader, we'll never see any further development for custom roms or root on the snapdragon version of the galaxy s7. Only other option is to get the international version (g930f) which has the unlocked bootloader and exynos processor.
I'm not sure that it is Samsung that requested phones with a locked bootloader. I believe it is the carriers that want a locked bootloader.
T-Mobile was the last carrier to issue phones with a locked bootloader.
So nobody with AT&T Samsung Galaxy S7 has root?
Why so many forums that used to exist??
Willing to help...
It took a lot of digging but I was able to get my 930a successfully rooted and stable. I would be happy to assist (with what very little I know) and see if we can't figure it out. I used almost all links from XDA, if not all, but it did take a little time to put it all together. I had to flash the 930u firmware and then I had to play around with a few things. But I was successful and it does work and it is very stable. Let me know if I can help, I am going to totally unroot and reroot mine again so I will be going through the process all over anyways. Would love to be of some help, this is actually my first post on XDA so figured what better time to jump in. Take care

I have mine stuck in boot loop i am trying to just to get back to stock would u be able to assist
hi all
i was advised by a friend to post my issue on this forum as someone here will always have the answer after searching the net without any luck.
i have a uk model s8 on the o2 network which was originally locked to o2.
so i took it the local market to get it unlocked which the market trader did and it accepted another uk sim
but wont connect to any network now. states emergency calls only, even with my original o2 sim.
i cant even search for any networks. when you try to search for networks by choosing the phone option, nothing happens, just states not available at this time. same thing when you try to choose manual or automatic search.
it accepts any sim now but wont connect to any network.
i thought it may have been barred even though i bought it 2nd hand and had it over 8 months so i checked imei on the net and it comes up clean. so not barred.
went back to market and the street trader said he will flash with firmware to fix. he said it was running latest firmware, android 8.0 dec 2018 G950FXXS4CRLB [december 2018, revB]
but will flash G950FXXU4CRL3 [december 2018, rev3]
but that did nothing. he said he wasnt sure why the phone is not getting a signal and confirmed it was definitely not barred.
he couldnt also understand why you cannot search network, why this option cannot be selected.
so this is where i am.
any help or guidance would be appreciated
regards,
Margaret acey

Did you check IMEI online or wih the original provider sometimes online services don't show blocked imeis I have a US model rooted and sometimes the radio crashes and and have similar issues. I have to reinstall the CP and csc from the firmware files to get it back up. Using the latest Odin and firmware. I assume your on the latest firmware
thankyou for your reply,
i have not checked with network but i have tried multiple websites who offer imei checking services and they all show clean imei.
in respect of firmware,
it was running the latest firmware which was android 8.0 dec 2018 G950FXXS4CRLB [december 2018, revB] which didnt work
then the market trader flashed an earlier version, stil android 8.0 but two weeks earlier version, ending with CRL3 and that has not worked either. so at the moment its on that version.
both these were released by samsung in december 2018 but neither work,
so i dont know what to do.

I would take it back to the individual who unlocked it. It worked before and not after.
yes i did that but he said he did the unlocking and that has worked so is not taking responsibility for the signal. so i have to fix myself.
can anybody offer any help on what to do please.
Does it matter which mode you select? e.g. are you able to choose 2G/3G/4G autoconnect?
My S8 suddenly lost connection to just the Vodafone 3G network in Australia but is able to connect to other carriers on the 3G network fine.

it wont let me select anything, any mode at all.
when you select option, nothing happens, it doesnt go into that option.
ive have a message from a member on this forum, named "ZeroXO" who said he can fix this but waititng for him to get back to me.
he said he knew what the problem was, took my imei no last night and said he will get back to me. so hopefully he will find a solution for me.

Ok that's not even as far as I got.
I went back one firmware version to the one that I was running before the one that started developing the issue (although it ran fine for a week or 2 after the update) that didn't help.
I forgot if you tried to go back to an older one as well or tried one of the country specific ones. You need to check if you've got the snapdragon or the equinox version though.
Hopefully the other guy manages to fix your issue
Thankyou for your kind words and advice.
I changed firmwares a couple of times all 8.0.0 but no luck.
Ive got a member from this forum currently trying to fix it as we speak. He has made a lot of progress and clearly know his stuff and happy to have his help and assistance so hopefully it will be fixed today so ill keep you updated and let you know how i got on.
Thanks
margaret
Can i also extend my thanks to another member named pblim (not sure if i have spelt that right)
Who helped me yesterday to show me how to hide root.
Fantastic help and advice from him. Very kind
Highly recommended member.
So thanks mate.
Regards
Margaret.
