Network unlock Galaxy Tab 4 8.0 LTE (SM-T335)?

Does anybody know how to remove a network lock from a galaxy tab 4 8.0?
There's loads of apps on the play store but none seem to work.
It's currently locked to Vodafone UK. It's rooted and model SM-T335 LTE
Cheers

And that does not allow Vodafone to download applications from the Play Story? If yes , then try to install the firmware is not from Vodafone .

I can install play store apps but they seem to fail to unlock it.
Am I able to flash an unbranded equivalent firm over the branded Vodafone one?

Yes. It is branded with some vodaphone (UK) apps.
Im trying to get the original owner to contact voda, but it's slow.
If i was able to flash a BTU firmware over this, would it remove the sim lock?

If you do need or want the BTU firmware (as opposed to the Vodafone firmware) here is a good download link (android file host). All the other download hosts are some combination of slow, buggy, or unreliable.

Thanks for the info. stumbled across that file when I searched for roms. (i take it that you hosted theose files?)
My tab4 is now rid of the voda stuff, but lost root. I used autoroot to get it back (tripped the knox tho)
Just waiting for the SIM unlock code....

U Firmware Step By Step

Would Anyone Like To Post Detailed Instructions On How To Flash The "U FIRMWARE"? .. Also (if possible) could someone include all the necessary files & give any details on the firmware (i.e. Pros or Cons).. I've seen it mentioned in a few other threads, with some people making claims that it's much smoother, also the root is more stable on that firmware. But I can't seem to find a dedicated thread on it. So if there's one out there post the link or feel free to comment instructions, any useful instructions will be added to the OP

Hi, here's something from our friends with a Verizon s7 edge, they've written a step by step on how to flash the U firmware and what to do afterwards. What You and us t-mobile users need to flash is SM- G935U (TMO region) firmware which u can find on sammobile.com. Please read the instructions carefully and best of luck with flashing. Cheers!

Yeah it will but you need to find the right one on sammobile. The one for G9535T TMO region next to itself. The the rest of the procedure is the same as described in the post i shared. I will it leave it to you to do some research on your own and find the right files. Cheers!

Hey all, best place for U firmware is THEANDROIDSOUL.COM . they also have all other Samsung firmwares. So good flashing

Does it require root to flash U on the tmo variant?
Does it trip Knox?
Thanks

Keep in mind there's also a lot in here that doesn't pertain especially if you don't need root so be careful people, this as Mag says is for Verizon but the process is the same just make sure you have the T-Mobile files if on T-Mobile. You can download at SamMobile I have a SM-G935T which is now a G35U with the new modem APK1 and have wifi calling and VOLTE in my mobile network settings and ZERO bloat which is why U firmware is desired. It doesn't have any carrier bloat because it's not for any carrier so none have installed all their bloat so it's very fast. You will lose root and everything but can redo it and reroot also.. just make sure you're getting the right files and not flashing VZW on to T-Mobile etc etc. I ALMOST did then realized lol. I Got excited. I was never going to root so none if that mattered but I tried it and after all the suggested tweaks and fixed it still ran unacceptable for me so I'm not rooted at all now. Too buggy and too many weird FCs and errors/bugs so I factory rest and flashed U and new modem and my phone has never been faster even when rooted and CPU setting tweaked etc. (Too many bugs as stated)

No because you're flashing an official firmware not a rom. No root and won't trip Knox as other have reported. This is true for all variants since it's an official firmware.

Prob not. Many people including me have done ALL of the post root modifying to make it run better when rooted with very little success. I tried every single post root method to try and get it stable and nothing made a difference and if it did it sure wasn't stable anyways. So bad that I Reodined the entire thing and started fresh and didn't root. The root is very unstable and simply not worth it. I don't need root for anything I care about anyway and my S7 Edge is plenty fast. and running the U firmware there's no bloat except like 2-3 apps which I can live with and that was one major reason to root anyway (to delete the bloat) so meh to root for me.... If you read back many have reported this. I don't need nor want root and when I saw how bad it ran I immediately re did it all. Now it's lightning fast, I get amazing LTE speeds because if the APK1 MODEM and I'm in one if the 319 cities supporting the 4x4 MIMO LTE that the APJ1 Takes advantage of. My LTE is faster than most people's wifi. So I recommend d regarding the Odin and forgetting about root. It's just too buggy and I'm by no way a noob. Been here fir 10 years so I know what I'm doing and I couldn't get it stable enough even applying every single post root suggestion. It ran like crap and wasn't even usable unfortunately. No offense to the root team whatsoever they achieved root and kudos to them it's just not established enough to be a daily driver sorry to say.
My latest LTE speed abiut 20 mins ago. Not wifi....LTE..LOL it's amazing if yoyre in T-Mobile and you're in one if the cities supporting it. I imagine everywhere in the US will sooner or later it most cities. It's relatively new but I'm getting speeds unheard of. Before this I was getting like 10 mbps download and 8 Mbps upload
Not it's more like 6p-70 and 40-70 depending in where in my city I am. It varies deoending on how close to towers and what not you are if course. But damn it's fast.. wow

is there a way to install this U firmware and then simply root it and not install all the other junk? I love it running U stock with the new modem because it HAULS ass, but I want to root so I can edit the build.prop and since you have to be rooted that's hay I ask. But the root causes all kinds of issues and post -root stuff needs to happen to get it even stable which none worked for me, a few did but it ran horrible so I immediately returned to stock and redid the U firmware. so is the something like a way to just root for file access only without it modifying anything else? I doubt it but don't know much abut the U firmware except it runs amazing until rooted at least from everything I'm reading. a couple peeps claim there's is running amazing even rooted but I have doubts...mine ran like total crap even after applying all the tweaks and kernel settings with Trickster and the like (which I know how to use very well and bought it and have owned and used it for years....any ideas? I want to edit the lcd from 640 to about 580 is all and don't want to root if it's going to bork everything up again...

Hi -
I am a person that just has to have his phone rooted. Dont ask me why, but I do. And I love custom ROMS. Since I do not really see any custom ROMS for the S7 yet,
I will settle for just rooting my S7, I was hopping someone would be kind enough to point me to the correct files needed to ROOT my phone and maybe a small odin walkthrough.
Phone info:
Galaxy S7 SM-G935T 6.0.1
Baseband G935TUVU4APK1
Build Number MNB29M.G35TUVU4APK1
Also ... what about TWRP support ? I want to be able to nandroid backup. Is there a version of TWRP out yet for the S7 ?
Thanks all !!

Follow the instructions in the O.P. of the post-root issues *exactly*. Don't skip anything and don't add anything. Trickster is not listed in it. I followed it exactly and my rooted U just plain smokes!

The answer to both of these is that since the bootloader is locked, you can't install custom recoveries which makes custom Roms a lot harder (but not impossible!) There's two that are in the Roms subforum (TEK and Echoe) but I've personally found stock U firmware + root to be the fastest/most stable.

Is your reason for "have to have root" for a specific reason or no? This root us really laggy and buggy as hell so if I were you I wouldn't do it. There's no Roms really. Well two I think but it's going to be more if a headache than the benefit of root. No one "has" to have root. What do you need that's so important by rooting. That's silly....

I'm not sure bud. I LOVE the U firmware and the APK1 modem for Tmobile have made my LTE VERY fast and the U firmware as well with ZERO bloat. I wouldn't downgrade anyway but can't answer your question, I simply don't know. Are you on ATT or something? I haven't heard of that firmware even...but I've been on Tmobile for about 6 years or so...

ok make sure you download a rom toolbox or something and go to data/imei/theres a dat file you can read it as a text file.make sure it says VZW ok and check your apns and see if the build.prop took the prop setting at the end for verizon and one more thing make sure the csc took also..thats it it should be good to go....

Is it possible to flash an international rom and change the apn?

Well with my experience it does have to be sprint involved because it's a CDMA device.that's what I look for before I switch out Verizon files to sprint..I ran into bad provisions with the simple card because I didn't switch out the files before.make sense

S8 downgrade from Version 9

Hello, Smart people
I tried to search but couldn't find any proper solution. Is it possible to downgrade S8 running on Android 9, I want to install version 8 on it.
Thanks

i am also interested in doing this. i have had my phone for over a year, i was very careful never to download. the other day it popped up as i was taking a photo, and wham. normally i would have ripped the battery out of the back. but no such chances anymore.
the new os sucks huge. big stupid buttons, changes to the camera, the messages are pure misery.
i am on bootloader build 5. i have tried to use odin several times, only to discover this bootloader number thing on these forums.
im going to be furious if last week i was build 1.
at this point i would consider rooting the phone only out of spite to samsung for not letting me customize my phone anymore.

You can only go back to Android 8 if you have bootloader version 4. Use this code on your phone *#1234 # to know your version of bootloader.

Thanks

You do not need to shut down OEM to downgrade! Respect only the bootloader version, otherwise it will brikar the cell phone, downgrade before the April patch as it is coming with bootloader version 5.

how do i shut down oem?
also, i hit the code to get the bootloader version, and all i get is a ussd error.
---------- Post added at 02:40 AM ---------- Previous post was at 02:23 AM ----------
damn my bootloader says a bunch of numbers then 5 towards the end.
so that means im on b5.
is there a way to downgrade this to the old software if i am at b5?

Use *#1234# or App https://play.google.com/store/apps/details?id=org.vndnguyen.phoneinfo
You do not need to disable OEM to downgrade.

bootloader is
g955usqu5xxxx
again, freaking phone popped up the offer to download at the exaxt same second i clicked to take a pic. thats pure garbage there. now i am on bootloader 5.
this is an s8 i am using, but i have a brand new s9 i have been holding back to use.
i want to fix the s8 before i stash it into storage as my backup.

You can not because Oreo uses bootloader version 4, forcing a downgrade will turn your phone into a brick.

He is right, I did not realize that you use snapdragon and there is yes oreo with version 5 of bootloader so you can do Downgrade normally.

thanks so much for helping guys!
what is the oreo version i have to hunt down.
im on t-mobile.
i tried to backdown using odin, it kept giving me errors. does odin protect the phone lol?
so if i get the proper oreo os, with the boatloader 5, odin will work?
thanks again for helping me out!!!

hey, which one is the one to use? android 8 is oreo?
i tried two 7.0's, and i might have tried the earliest 8.0 on this list.
do i just go higher up, and odin will just bang it in there?
thanks so much again!

I came back to the Oreo, well done system, with fluidity and great performance, Samsung Android Pie is crap.

Need to Flash an S8 used on Straight Talk

A friend of mine gave me an S8 phone. Its reset and wiped clean. I was trying to set it up but it requires his old gmail account and password to get in to. The problem is, it won't take his password. He emailed google about it and he's waiting to see if they will recover his account on it. He won't be using the phone anymore as he has a new one. I'd like to use it as I have an S7 and this one has double the storage space that mine has.
If they can't recover his account, I want to flash the memory and start over. I've been a computer tech for 20 years so I know all about flashing the BIOS and how that can brick it. My question is, since I can't get into the system of the phone and see what the version of the firmware is, how confident can I rely on the back of the phone where it says SM-G950U? I've read that even though its branded that way on the back, it doesn't necessarily follow that it will show that in the system. I've downloaded the newest firmware I can find for it, SM-G950U_201910251442240_c0osvhilm6_fac from Updato and will use Odin to flash it with.
This was used on Straight Talk and has Tracfone branding on the startup.

Am I missing something. You say this is for his device. You linked s8 active stuff to a user that has a. 950u. This is not for his device. Luckily Odin don't allow flashing of wrong firmwares. You just bricked a guy's phone.

My mistake, I knew what phone he had I mean it's clearly written in the description. It looks like I posted the wrong link ACCIDENTLY. Nobody's phone was bricked. Well mistake made and valuable lesson learned. As far as the way you came at me questioning me if this is for guys device is pathetic to say the least. How you gonna ask that when it clearly says that. If this is what XDA is all about you know just read your response to my mistake, I won't be part of it. I'm about helping people and not smashing them when they make a mistake. Clearly you feel it's necessary to talk to people like that. What's that say about you?

You know I've been sitting here thinking about this. And it's TRUE 100% most of the bricks and bricking does happen on the locked us devices. Me myself even have a semi bricked one just sitting here to no avail of fixing hours and hours spent. They are a lot more finicky it seems than a unlocked bootloader ???

I'm sorry but I'm still having trouble getting this to work. I've tried the combo file and putting the extracted file in the AP section, and while that works, the phone just goes into a loop from the Factory Binary to that Settings screen and once its rebooted, it all starts again. What am I doing wrong? I've reset it to factory data several times.
Phone is an S8 64GB SM-G950U used on Straight Talk. Has Tracfone branding on screen when booted.

This is one of the latest bit 7 firmware. It is u1 unlocked carrier bloat free. This is what I use in mine. Sam mobile is slow. You can try internet download manager to speed it up a bit. But if your over seas or wanting non branded this is the way to go.
