Sprint A205U Flash Firmware To MetroPCS - Samsung Galaxy A20 Questions & Answers

I have a Sprint A20 that hasnt been sim activated and unable to locate OEM unlock. I have tried to flash the MetroPCS firmware on to this phone but no matter what i flash, the Sprint firmware is still installed after reboot. I receive no errors during flashing and everything succeeds, but no sign of the flashed firmware upon reboot. Any Ideas? Thank you.

You can't unlock the bootloader of A205U, that's why you can't see then OEM Unlock on dev. options.

In the Samsung Galaxy there is one important rule.
U shall not root.
You're knocking on the door but Samsung has locked you out.

Im not looking to root though and i dont even want to use any custom rom or any of that. When i flash metropcs successfully, i just want it to stick when the phone boots, instead of Sprint firmware magically re appearing. If its a successful flash with official firmware, then why wont the Sprint firmware go away / be overwritten, especially when it is a successful flash. Maybe i am wrong, but from what i remember, even when bootloader is locked, you are still allowed to flash official firmware, or am i wrong?

I get stock firmware from sammobile.com. You'll have to register but it's free.

scroll to the bottom and enter the requested code to initiate the download.
When returning to stock. I used your all in one to root, do I need to unlock the bootloader or anything.

I have tmobiles 8.5 gb data plan. yesterday I downladed a large file. This morning my data connection was really slow. So trying to work around their throttling, I went into the service menu and changed he network control>band preferences to CDMA/LTE only. Worked for a while and then things returned to normal. (Slow crappy service.) So i went a little deeper changed something else in cdma selection ended up without any service at all. Then after a lenghty talk with att and tmobile I decided to do the process to turn on aws again. After doing that the service returned, but the data is still the way it was.
I actually had it where it was saying it wasnt activated asking me activate my phone.......yeah stupid I know I shouldnt mess with things especially when I have no clue what they are. Lesson learned just trying to fix my mess
PS I am not over my data limits

When you return to stock, you're staying all over again. You'll have to reroot, etc. Be sure to be wary of your device trying to grab the MF3 update. Maybe take your sim out and leave wifi off while you root, backup and flash to your desired rom

Don't worry about the boot loader. It's locked and you can't unlock it. After returning to stock with odin re-root it using motochopper. Do ask that with the sim out and WiFi off so you don't get the mf3 update.
See this http://forum.xda-developers.com/showthread.php?p=42320391
Man I am starting to get frustrated,,,,,,,,,.,,.,.,,.,.,.,.,.,,..,,,.I know how to root. Motochopper is what I used to begin with to install twrp and root. My phone is not coming up in odin I have all the current drivers any other things I need for the s4. I have been modding since the s2. But I am very new to the s4. Why doesnt it show up in odin?

Delete the Samsung and kies drivers.
Run ccleaner
Install the Samsung drivers
Then run Odin
finaly got odin to work flashed and rebooted. i thought flashing a rom would delete a lot of my stuff? It is all still there and now my computer doesnt connect to my phone it charges it but doesnt say it is connected.
I have tried different cables and different ports with no luck.

Odin won't touch your internal or external sd cards, the areas you store pics, music, etc. So what your seeing is normal.
So what about my other problem now? My computer not connecting to it.

Need help asap please - SM-G935W8

So I was setting up my device yesterday and enabled fingerprint unlocking and choose a pattern unlock and written password as backup options.
When I restarted my phone, in order to unlock the phone it stated to use pattern unlock to protect fingerprint scanning after reboots (something of that nature).
Problem is for some reason I cannot figure out the pattern to unlock (I'm sure im using the one i set in place) and I cannot use my written password to unlock either, it's just by pattern.
So am I locked out of my phone and don't know what to do. I'm trying to do a factory reset to see if that'll work.
But I also flashed twrp and noticed that this model cannot be rooted so i left the custom recovery as it is. I do not want to swipe right to "allow modifications" as I heard if I do not install the right files it might be stuck in a continuous loop. So I clicked on Keep Read Only. When I try to wipe it keeps on telling me it's failed is it due to being in read only (I also don't see any of the contents on my internal storage)?
Should I flash the stock recovery with odin but I cannot find it for this model. Can someone point me in the right direction?

GT-i9505 S4 (Globe Telecom) Rooting and Flashing

Greetings GS4 Community! (just moved from LG Optimus Black)
I just got this GT-i9505 Galaxy S4 and it's openline but the signal bar has a letter "R" above it which I assume to be roaming. I'm having some thoughts on flasing custom ROMS and I was wondering if that would affect my current network status? I'm worried that if I flash a new custom ROM, the phone will be locked on the carrier (Globe). Not rooted yet and I was wondering if you could help me out here
No, it won't affect your network status nor be locked on your carrier. :good:

If the phone was neverlocked then flashing won't change anything.
But if the phone was locked and then unlocked at some point, it might lock it back.
It depends on the unlock type used. Some unlocks are permanent.
But if you bought it unlocked from the store/carrier, then there is nothing to worry about.

I was unsure of that though, might ask the previous owner for that thank you for the replies sirs. I'm trying to root the said S4 via odin by trying to flash the latest TWRP recovery via odin but the odin says

Rooting can be done without the need of a custom recovery.
Did you un-tick re-partition in Odin before trying to flash?

the unit is from Globe and I have this annoying globe bootlogo at startup
UPDATE: Got to flash the custom recovery and use a custom rom Lollirom V9.0 the problem was the sync cable not sending enough current to the phone which causes the issues with the odin.
For those who have the same carrier and baseband, you can safely flash a custom recovery (CWM) and flash a custom ROM. It will be fine, networks still there even after I updated the modem to PA1. Goodluck

FRP Locked S8 G950U

I have a Galaxy S8 that is FRP locked.
The exact model and version is: 8.0.0/R16NW/G950USQS3CRE2
From what I understand this has the v3 bootloader and Oreo, correct?
I need some help getting this phone unlocked. Anyone care to lend a hand? I can use Odin and ADB just fine, I just need to find the correct files needed for the version I have.
Also, if I can actually get the correct files., can someone outline the steps needed to do this? I've been trying to unlock this thing for about three weeks and my brain is turned to mush with all the things I've tried.
Please don't send me PMs trying to get me to contact through other means.

Hey. Don't worry. Frp lock is a protection for your phone this occurs when your oem lock is on. To unlock it go into developer options and then tick the oem unlock option . But for now your phone locked all you can do it flash stock firmware using odin . That's the only way . I know the data ma be precious inside the phone but it be useless until phone in not booting . So ho and flash stock firmware for your device from sammobile.com
Thats all . I hope may this helps you and inform me as soon as possible.

Yeah, flashing the firmware doesn't reset the FRP. Tried just AP, AP and BL, all five, doesn't matter. On first boot it requires the previous owner to log in. It's stored somewhere that's not touched by the flashing process somehow. Or it fails. After doing all five files on first boot it says it's installing something, gets into the 30% range, then says erasing for a bit and reboots.
Is there any way to do this?

flash a combination file factory reset from combo then flash legit bit 3 or higher firmware. The 30% failure after erasing is normal. 32% normally

Its test and diagnostic firmware released by Samsung. It is not a usable rom. You'll flash this. Factory reset from inside the settings menu. Then you can reflash official firmware. And you should be good to go unless this has been patched

So I went ahead and flashed the combination file in the first link and did a factory reset. Now when I try to flash the files I already have it fails. I'm assuming that's because I flashed a bit 5 combination firmware, and the stock files I have are not bit 5.
How do I know which firmware files I need? Do I need to do all files (BL, AP, CP, CSC) or just one? It's very hard to figure out what to do when everything I read is different.

Yea you need bit 5 files. Flash all 4. If you look at a firmware number. 5th dig from far end will be a 1-6 that's the current bit, anti rollback whatever you want to call it.

I am currently downloading a file called G950USQU5DSC1. Should be bit 5. I'm pretty sure it's for Sprint, and this phone was originally Verizon. Will this be a problem? I'd very much prefer AT&T or T-Mobile, but Verizon might be OK if I'm locked to it.

verizon firmware is unlocked sim wise sprint firm probably wont work but also should setup based off of your sim card inserted.
dsc1 i believe is pie which is awesome on s8 you can change carrier also with the combination file pretty much as your doing with each personalized firmware to each carrier

I'm grabbing the file from this page: https://www.theandroidsoul.com/samsung-galaxy-s8-firmware/
How can I tell which carrier is which? I'd rather just flash the correct one off the bat. Looks like the only one on that page for the 950U that is Pie is the Sprint one. I don't have a SIM. Well, I could take the one out of my current phone temporarily if it'll help set it up correctly.
Is the process for switching carriers just flashing the CSC file? Or is it more involved.
EDIT: There is a CRK1 file that is U5 and Oreo. Pretty sure that is Verizon. Cancelled the other file and am downloading this one. Going to take a while, using my phone as it's faster than my home internet.

The CsC determines sales code and carrier setup. I use sammobile or updato.com they have all firmwares needed
Boom. It worked. Typing this on the S8. Even accepted my AT&T SIM and connected to data.
Flashed an 8.0 firmware, but it seems to be getting updates. Maybe it'll update automatically to 9.
Anyway, thanks again. Free S8 is nice.

that firmware is from sprint. something worth sharing is that all S8's designated for the US market are literally the exact same physically. You CAN flash whatever firmware you want for whatever carrier on a g950u. You will need a modified version of Odin to flash firmwares originally intended for a different phone tho. I had the FRP lock on my dads old S5 the other day, but i was able to get thru it with my gmail information oddly enough. Not sure why google thought that authenticating use on that device per my gmail account credentials was ok, but..... ok i guess.
Once you get the phone up and running, put a sim card from whatever provider you intend on using in the phone, if it asks you for an unlock code, then youll need to get one from the original carrier it was intended for or a third party paid site. AT&T has a sim unlock tool on their own site you can try.
Teh reason i mentioned that all the S8s intended for the USA are literally identical is because you can take a sprint S8 and use it on Verizon, AT&T, T-Mob blah blah provided youve flashed the correct firmware, which is either the U1 version or the bespoke firmware for that carrier

Very good info. Thanks.
When I first booted the phone after flashing I had put my StraightTalk AT&T SIM in and it connected right away. It also started downloading and installing system updates, all the way through the Android 9 upgrade and the August security update. Pretty cool. The only thing I see is after a reboot or power on a notification pops saying that a non-Verizon SIM is installed. But that notification can be dismissed, and as far as I can see doesn't recur until next boot. So easily ignored. And there's Verizon specific bloatware. Maybe I'll download AT&T and T-Mobile images just in case. I've been thinking about carrier hopping, as I have pretty poor AT&T coverage in my area, since with StraightTalk I can get a Verizon SIM added to my plan and take my AT&T one off pretty easily.
I haven't really used the phone much yet, as I'm waiting on a case, but I'm not sure I'm going to like the Samsung skin. I'm used to a very stock Android experience, as I've only really used Motorola phones and my current Nokia 6.1. I just like plain vanilla Android. But I'll give it a shot. Already installed Nova Launcher and F-Droid.

Galaxy S8 bricked - Stuck in boot loop after flashing twrp

Hey there everyone,
I wanted to root my s8 (sm-950f) and when I flashed twrp my phone initially got stuck in Samsung logo. After managing to shut it down I tried to go to recovery mode to wipe everything and perform a factory reset but I can not do it. All that happens is I get to s8 screen and it reads in red on top left of the screen "Only official released binaries are allowed to be flashed" and it keeps resetting itself. I can access download mode but that's it, I can't do anything else. Currently downloading a stock firmware to try and flash it but with the free downloads it's taking its time. Any help appreciated, I really want to unbrick my phone
note: It shows FRP and OEM lock to be off in download mode, i dont even know if i'll even be able to flash a new fw. Do I just have a very expensive brick in my hands now?

This must be a international S8... Did you activate oem unlock in developer settings before flashing twrp

I'm not sure if it's international, it's most likely a Turkish version.
And yeah to your question

But you know for a fact that there's a twrp version for your device.... Not good to do these expensive phones like that without officially having all the facts

Well it's too late for that now, I need actual solutions. I also tried smart switch - it doesn't recognize the phone

On the xda thread for your device there aren't no stock roms uploaded to Android host for fast download so you can flash in Odin and start the process of twrp again or just leave it alone you have a S8 it's good money

WHEW. Flashing a stock firmware seems to have fixed the issue. Mods can lock the thread.

You going to give up on twrp

I do want to root, but I don't want to approach it without knowing all my facts, do you have any suggestions for guides for Android 9.0?

Just look in your device forum everything Is there however your device is a international cause it ends in with the F so twrp does work for your device..... You just need to find the specific one for your model once you have twrp you can install a android 9 custom rom

Sorry but I have a serious problem. I have activated oem and debug usb on developer option, but I can't install TWRP. I have tried with odin, prince cosmy odin, odin patched but FAIL everywhere, please help me, I just want twrp and i want to install a custom rom. thanks in advance everyone. If is a problem answer me here, you can send me a pvt message. I tried it from 3 days with the same FAILS :_(
I had this problem too a year ago but wasn't able to reflash the official firmware, but when I went to Samsung they fixed it for free even though Knox was already tripped
