What i have: a brand new carrier unlocked samsung galaxy s7 sm-g930w8 - came with 7.0
What Id love to do: downgrade to 6.0.1 official touchwiz rom but rooted
What im reading: that the security patch is from february of 2018, which means the bootloader is too new, which means downgrading using odin wont work ( https://www.sammobile.com/forum/threads/36282-Does-Region-Matter )
... so what can i do? i bought this phone with the sole intention of downgrading, as ive seen that it is possible for that phone model (s7) in general
i hate the look of the newer OS. They took the touchwiz out of touchwiz which i loved, although mine is a rare opinion. I want the operation and exact feel of 6.0. the menus are simpler, the notifications area isnt completely stripped of features differing from total stock android. i hate having to pull down twice to see everything. I just really want that older look and feel, but all around, not just a theme.
is there anything i can do to either downgrade or fool the bootloader into letting me carry this out? is this a true limitation, or si that info i found false/old? and if I can downgrade, which build version should I use?
ive been looking here for versions
https://samsung-firmware.org/model/SM-G930W8/ but im not sure which region to go with, or if i can technically use any region
sammobile doesnt list that version anymore at all ( https://www.sammobile.com/firmwares/galaxy-s7/SM-G930W8/ )
https://mobiletech360.co/samsung-galaxy-s7-sm-g930w8-stock-firmware-rom-android-6-0-1-marshmallow/ there are a number of options here but unsure of the different numbers/builds. or if since its carrier unlocked, i could pick any?
I know most will think im silly for wanting to downgrade or caring that much about appearance, but silliness aside... is this even possible??
a while ago, i purchased an s5 mini, and downgraded that with no issues at all.... but its honestly been so long and i cant for the life of me remember the steps i took or if i needed to care about region codes or other numbers. but it did sucessfully work.... it was really built unwell/cheap, but it did work.... its also slower than my captivate glide which is still my current phone, until/if i can get this s7 working the way i desire.
any help and guidance is appreciated. If it is needed, ill be using it with a Koodo mobile sim.
well it is too new if its from DRAG or so onwards (those with U2/S2 in the file name) so no dice, you're stuck with 7.0 unless you want to upgrade to oreo. (and 7.0 firmwares prior to DRAG cant be downgraded to either, not that theres much point doing that)
btw this is the wrong forum to post this in

But this is the forum about s7? I'm wanting to modify an s7?
Which part of the file name are you referring to? Which file?
I would have thought all s7's are made at the same time, and so released with the same overall software, but it all seems so complex now. I've seen s7's running 6.0.1 stock so in my mind it seems they should all be able to...
Not sure what you're referring to with drag either? Does that stand for something?
I'm really hoping this can work somehow, its the last flagship before the edge models which was why I got it, and I love Samsung software up until 7 and 8.
My mom has an s7 as well, not rooted or anything that's too complex for her, but she did the upgrade to 8 and it's still got all the same gross appearance factors that I don't like about version 7. I got excited when her phone wanted to upgrade, maybe they had fixed some of the grossness. But, nope. Wish they had included an option even for stock based or touchwiz based appearance and menus.

go into about phone and tell me the last 6 characters of your build number
(i was referring to the PDA file in a stock firmware zip)
(Also i meant this should be in Q&A section)
Hello,
I can understand you and also understand what you want but Samsung installed a downgrade lock in their bootloader in early 2018,
if you installed this version you can't go back to an older version, I think that was in February.
You can go back from a 6.2018 version to a 4.2018 version for example but not to a 1.2018 version!
If you have a version of for example 12.2017, you can also go back to a version of 2016, so you can also go back to Android 6.01,
if not you only have the last versions of Android 7 or update to Oreo.
I hope I could help.

the last of the build number and the last of the baseband version are the same. But i did take a screenshot of it when i was thinking rooting and changing would be no big thing. figured that would be easier. i purposely havent even hooked it up to wifi yet or anything, said no to anything non essential when i was setting it up... on the chance it was starting up in version 6, and i didnt want it upgrading on its own.
also why would they block downgrading? It seems if anything blocking upgrading would be the way to go, to stop people from updating their devices before official software is ready, not just samsung but any manufacturer. in my head it seems silly to even need to root anymore... someone always figures it out, and cell phone manufacturers must know it. it would be nice if it were included, sort of like developer options, where its hidden, but if you know what to look for its there, and if youre not that advanced youll never find it.
if the bootloader is in fact locked and that is the main prevention, has anyone ever successfully unlocked it before?
ETA: Ive done a bit more looking around and there is alot around about frp and making you sign in to a google account in order to reset.... i have *not* needed and havent signed into a google account on that device at all... does that mean a downgrade is still possible though odin? Or, are these 2 things in fact unrelated...
eta #2: Did a bit more searching around, and it seems to be that in order to root your device, in the process it must unlock the bootloader? If that is still the case, would i be able to then flash the marshmallow stock ROM? Thats what i was looking to do all along, sorry maybe i should have been more clear about my planned method initially. Its a bit more nerve wracking as it seems rooting itself has gotten a little more difficult with that dm verity thing... but I definitely want root no matter which version im running. Ive had root on all my devices and theres no way im going back to a locked down OS (cant remove microsoft stuff for example), i need to be able to declutter beyond what factory allows lol.

TL;DR
your bootloader is currently on version 3, and you cant downgrade to marshmallow
see that "U3BRB2"? that "U3" means your bootloader is on version 3. i assume the marshmallow firmwares use bootloaders pre-version 3 so you cant downgrade to firmwares using bootloaders with version 1 or 2. (this is how it works for F/FD models and im pretty sure samsung made it like that too for the W8 models)
eta 1) unrelated
eta 2) F/FD/W8/S/K/L variants (basically all the exynos models) have unlocked bootloaders. only SD variants have locked bootloaders so it's just your misconception
So, it's literally impossible? Has nobody ever figured out a way to downgrade or mod the bootloader itself? It seems to me the rom makers wouldn't stand for this at all and would figure out a way around it...
I can see an old bootloader can't run new software, but it seems much easier for newer bootloader to run older software, isn't it? You can buy a windows 7 pc and install Windows xp on it much easier than you could buy a windows XP PC and install Windows 7 on it... It's just boggling my mind a little

Off course you can downgrade to Marshmallow. To unlock the bootloader, enable OEM unlocking in devlopper options. After flash TWRP 3.1.0 for Herolte and wipe everything from the recovery. Install any 6.0 roms on XDA for G930F then flash Magisk 17.1 to root and you're done. You can't FRP if OEM unlocking in devlopper is enabled.

You'll trip knox (which breaks features like secure folder, private mode, shealth and Sbrowser private mode) and lose the comfort of OTA updates if you do this tho. Not to mention that you can encounter signal reception problems because your flashed ROM is on marshmallow and your bl/cp is on Oreo or nougat. So I wouldn't advise this method as it may break so many things.
There's been a lot of new users picking up cheap G7 ThinQ G710ULM (US Unlocked) versions on ebay lately, then getting frustrated when they find out it a hacked Sprint version (G710pm).
I'm finding posts from new users on different corners of the internet, Telegram groups, Reddit, etc, usually saying that they can't upgrade from Oreo and their device is missing a serial number, and the IMEI is actually from the Sprint pm version. I couldn't find a lot of info in one place about these handsets, so I'm starting this thread to discuss them. There's a good chance any ULM on ebay for a good price is one of these. I bought 3 of them for different people from different sellers, and this was the case on all of them. I almost returned them all and gave up until I did some research and found out THIS ISN'T NECESSARILY A BAD THING!
In fact, it may actually be beneficial compared to the real ULM version in some ways. First of all, it WILL work with T-mobile USA just fine. The bands all seem to work, it even supports WiFi calling and VOLTE, and there's a chance even B71 will work (although this isn't 100% verified, it shows up as an available band to test in the service menu). The real ULM supposedly skips this band. Some people even say the real ULM version is also missing bands for AT&T, but the PM crossflashed version seems to connect to them (this might be an isolated incident or fluke, but at least one redditor claims this was his experience). I'm still not clear on how the unlocked official US version can be missing AT&T bands, so I'd love for other people to maybe chime in here with their experiences.
Yes, you can update to Pie. The OTA updates won't work, likely because of the missing serial number. On that note, I'd LOVE to find out why that is. Can anyone explain why these crossflashed devices are missing the SN? Does that happen on other crossflashed devices?
Either way, follow this guide here:
https://forum.xda-developers.com/lg...how-to-install-pie-stock-treble-aosp-t3914079
Note, this guide was written for flashing a European variant, but the same steps apply. Just choose a kdz for the ULM variant from here: https://lg-firmwares.com/lg-lmg710ulm-firmwares/#tab=firmwares
^ I recommend the latest Google Fi firmware version, which is G710ULM20e_00_NAO_US_OP_1010.kdz , from 2019-11-14
There is a more recent version from BPT, but it is unclear what that firmware is for. BPT seems to be some sort of regional carrier, so you are better off with the regular USA or Fi version.
Also note, you may need to use 7zip to extract the dll file from that guide. That took me a while to figure out, as Windows explorer throws an error with it. Once you finish, your phone will reboot with a shiny new (relatively) up to date Pie firmware!
There. You now saved yourself a few bucks and got a solid phone. Feel free to share your experiences with the handset here.

The devices lose the s/n and possibly imei because people are flashing using lgup 1.14 dev version which causes issues with nvdata.
Lgup 1.15 fixes this when you go back to oreo then update to pie.
Also crossflashed devices do not get ota because lgup marks these devices as crossflashed in nvdata using a 0x01 value for certified_device

Wow, that's some good info right there, thank you for sharing!
Hmm- messing with nvdata though? So you're saying the SN missing is some sort of accident or goof? That doesn't sound so cool. Should I be concerned anything else is messed up? There's a ton of these in the wild now and it seems the SN is the only weird side effect that has been noticed.
As far as I know the IMEI is fine (looking it up reveals it is a PM imei, which is correct, and it does work with voice over Wifi and VOLTE, which I think wouldn't work if the IMEI was messed up). In fact, it's interesting because when that screen loads in Settings>About, etc, it shows "checking" under S/N, then checking goes away and it comes back blank. None of the other fields seem to need any sort of checking first. There's something fishy about how the S/N is stored that it has to check it first and then error out.
Lgup 1.15 fixes this when you go back to oreo then update to pie.

Hmm. It came with Oreo, and I used 1.15 to flash to Pie. So you're saying I should flash another Oreo kdz with my LGUP and it will magically fix any corrupt NVdata?
Also crossflashed devices do not get ota because lgup marks these devices as crossflashed in nvdata using a 0x01 value for certified_device
Click to expand...
Click to collapse
Oh, that is unfortunate. And that value stays with it forever, even if you go back to it's native firmware? I'm assuming that value can't be manipulated with any of the tools we have available.
Thank you so much for sharing this knowledge. Any insight on how the bands work? Is that from nvdata as well, and completely independent of firmware? So essentially, I have whatever band support a G710pm has? Or perhaps was it manipulated by the seller/refurbisher, who possibly used some nvram voodoo tricks which killed the S/N as a result?
Even tho the s/n is blank and at time if you try to show the imei it might also be blank, it is still stored internally and not lost forever.
There is multiple oreo's which for ulm is 10g and 11g, but i would have said flash to the original firmware but you cannot as sprint kdz is not available and the people who have an Original firmware still on device cannot or will not back it up for us.
The value for certified device returns to normal when flashed to the original firmware as lgup has an internal database used for identifying models.
As far as the basebands, all g7 thinq's come with the same bands no matter the firmware or region. The difference is the kdz gives band priority to the ones prefered by the carrier.
All of that can be changed by getting into the lg data secret menu or the dialer code menu
Remember now bootloader and root for the LG g7 is just the beginning. You talk about nvdata you might as well throw out EFS backup as well.
The point is that TWRP creates faulty EFS backups on many devices which can't be restored properly. For our devices TWRP is barely universal. People selling crossflashed phones know this which is why they sell them.
I prefer the manual backup using adb shell you can do it with terminal emulator as well.
Qfil is very powerful for Qualcomm devices and we'll figure out how to make back ups of all partitions that involve serial numbers and IMEI ( nvdata and efs).
Just wait you'll see.

Thats already been possible since day 1, use qpst with your msl code to backup qcn with imei and s/n.

I don't understand. What does twrp have to do with any of this? My bootloader is locked and the stock recovery is still there. The devices are likely just flashed with LGup as is, and that doesn't seem to have effected much outside of a missing SN.
Are you saying that my cross flashed phone would effect things if I tried to root somehow? Or am I missing the point here?

Using TWRP to create a backup of efs. Sometimes the restore is faulty.
EFS partition holds up the unique IMEI number of the device, also other identifying numbers like MAC address, MEID, and ESN are stored up in this partition.
Check you IMEI with this.
https://imeipro.info/check_lg.html
To get your sn.
Oh ok.
So I don't actually need to know my SN but I'd like it to not be blank if flashing back to a previous version would restore it... Especially if there are possibly other parts of nvram that may be corrupt that I'm unaware of?
Thanks for the info. The one I got said it can't work on Sprint or Verizon networks, and is missing the serial #, as you said.
I got just one from bay with S/N missing and software version G710ULM10g. Latest patch level Sep 1, 2018 (Android 8.0.0). Is there any way to install Android 10 based ROM?
Assuming that after following the steps (Part 1 only) (hope we can skip part 2?) to somehow install G710ULM20e_00_NAO_US_OP_1010 (Android 9), is there a way to follow similar steps after part-1 to update it to Android 10 based ROM?
It would be great if someone can help to install Android 10 directly from Android 8.0 (without the need to installing Android 9). I am not sure if its even possible to get Android 10 on such bay unlocked devices without S/N.

If you must know the serial number there is a one site that you enter imei and it'll tell you what it is. Just gotta search on Google.
Serial number is lost when bootloader is unlocked. You can regain it if you relock and go back to stock. Not sure what version of g7 you have. More likely it's probably crossflashed and sold like that so there won't be a kdz to go back to stock.
Android 10 has a thread they tell you what kdz to crossflash too and how to update to android 10 with the activity launcher app.
I just got a 710pm off ebay. I unlocked the bootloader, crossflashed to ulm pie, and rooted. It works just fine. [emoji106]

There's another lgup dualmode you can use the partion dl option to install the Korean kdz that Android 10 uses. Search for that.
To install the Android 10 LGUP_FOTA.up update which you use activity launcher to install.

Thanks. My phone (G710PM) is cross-flashed with G710ULM firmware Android 8. Please suggest is below plan will work?
1) First update existing firmware to stock Android 9.0 i.e. G710ULM20e_00_NAO_US_OP_1010 using these steps.
2) Then install Lineage OS 17.1 (based on Android 10) because it needs stock Android 9.0 as a pre-requisite using these steps.

2) Then install Lineage OS 17.1 (based on Android 10) because it needs stock Android 9.0 as a pre-requisite using these steps.

Yes it will work.
I'd also like to add that Google Pay will not work, at retail brick and mortar stores.
A pop up says device may be rooted or modified.
I have magisk installed and it seems to trick Schwab banking app.
Edit:
Edit: I followed the instruction from the following video, and was able to get GPay to accept the card. Also Gpay needs to be manually hidden in magisk, be sure to select 'display system apps' to find it.

I am not an expert but I just bought one of these Ebay phones. It has Pie but what would like to know is how can I get the security updates? Or is that not possible? Please help. Thanks in advance.

If you're on Pie, I doubt you have one of these Sprint phones. Check if you pass SafetyNet and if so, you have a native ULM model. Most G7 variants receive very few updates (including the ULM).
I got a Sprint LG G7 phone from the bay that has been unlocked and flashed to G710ULM Firmware running Android 8.
I want to update to Android 10 if possible. I've never 'hacked' into a phone but am very familiar w/ hacking gaming consoles and feel like I am in familiar territory. With that said, I've read many existing guides and tutorials but have some questions?
1) How do i create (or find) a backup to my current FW in case of errors, etc.
2) Will flashing a FW from another country (Korea, Canada, etc.) render the network services (w/ Sprint) I have useless? In fact, will updating ANY FW render my networking services useless?
3) Do I attempt to flash an updated FW of the original Sprint model (G710PM) or an updated version of the FW that is flashed on the device (G710ULM)
4) Do i need to do an intermediate step of flashing an Android 9 FW or can i go straight to Android 10.
I apologize if any of these questions are redundant to any currently existing guides or posts. I did my due diligence of looking everything up as best as possible before posting these questions. Any help is greatly appreciated.

I'm newbie, but i try answer you in my understanding, and of course, i take no responsibility if something unfortunate happens :angel:
1/ i dont know any way to backup whole phone, but you can flash current FW (G710ULM) again via cross flash.
2/ i dont use Sprint, but my network service is work properly with Android 10 eu, canada and ulm (lasted is Pie), you can try...
3/ yes, via cross flash (update: there is no KDZ or Dump available. Probably in the future there will be dumps of 710PM but for now there is no).
4/ no, you can flash any version, any model (except tmobile) by cross flash way.
Hi. I know this is an old post, but does op still have Sprint firmware backed up?
If you do, I would love to get it from you. I can't seem to boot off other ULM firmware and I think I need an up-to-date Sprint backup abl, laf, boot, and possibly more. If you don't, have fun with your device and have a good day.
Hi!
I come from the Galaxy S series (S4, S5, S7) phones and I m considering of buying a Google Pixel 3
I can find many decent options, all of which are carrier unlocked
My concern with the Pixel 3 is whether I ll be able to install Android vanilla (without any carrier-related bloatware)
For all of my Samsung's so far, I could easily pick the retail ROM (well not exactly 'vanilla'!) from sammobile and load it with Odin (without breaking the knox)
Can I do something similar in the Pixel 3 or are there any security mechanisms to prevent me? (I m talking about installing original ROM - not custom..)
Bonus question - does any of you know if the Pixel 3 from Verizon and US Cellular have branding [carrier logo(s)] on the device?
Thank you in advance!
Well, you will certainly avoid the Samsung bloatwear. I have a P3 from Google and got my son's P3 through T-mobile. It did not have any additional T-mobile bloat on it, but I don't know about the big V.

I can find it via Verizon and US Cellular - hopefully none of which have put logos on it..
I have one more - rather embarassing question: do you have to use a Google account in order to use the Pixel 3? For several other Android phones that I know of - it's optional. You can still skip this step and use the phone without having to tie the phone with Google. But can you do that on the P3?
Any more hints on that and my ROM-related queries would be really helpful! Thanks

Verizon branded Pixel 3s have locked bootloaders, which prevent rooting or custom ROMs (vanilla AOSP would be a custom ROM). According to the flashing instructions at https://developers.google.com/android/images, you also need to unlock the bootloader to flash a google factory image.
I'm not sure if you can skip the google account. If you really want to avoid google services, my recommendation would be to install LineageOS, with no gapps.

Hmm...if the 3s has that, then the 3 will also have it :/
But I m confused...would I be able to unlock the bootloader?
I can see from this page: https://developers.google.com/android/images#blueline that 'blueline' is that vanilla AOSP version that corresponds to the P3 (right?)
The G account issue is less important. I just don't like 'syncing' stuff (accounts, photos etc). Worse case scenario, I ll create an empty profile, just for the logon

3s is not a model, it is the plural of 3. A Verizon Pixel 3 usually cannot be boot loader unlocked, but if you search this forum, you will find a few special cases where it has been done. One such case is at https://forum.xda-developers.com/t/...branded-pixel-3-how-is-this-possible.4267273/
Vanilla AOSP generall refers to a ROM without any google services. See https://android.stackexchange.com/questions/53171/what-exactly-is-in-aosp for more info. Blueline is the Pixel 3 factory image, which has all the google services. It does not have any added carrier bloatware, but I wouldn't call it a vanilla AOSP.
You can turn off all the syncing stuff, and you may be able to skip the google account part. I just can't definitely say you can skip the google account because I have not tried it.
Another consideration with a locked bootloader is the end support date. Google support for the Pixel 3 ends in October, 4 months from now. There will be no security updates from Google after October. If you have an unlocked bootloader, you can switch to LineageOS and continue to receive security updates. That is what I plan to do.

Clear!
I ll check on the resources you ve listed here
If the V-branded P3 is troublesome as it sounds, perhaps I should just go for the US Cellular carrier option. Bootloader may also be locked (but we know for sure that the V is..)
Interestingly, the US Cellular P3 is unlocked to all GSM carriers except Verizon, Boost, Virgin Mobile and Sprint
Is the carrier lock specified in the bootloader?
Btw, thanks for all the help!

SIM (carrier) unlock and bootloader unlock are separate, and not related. I have no idea if US Cellular is bootloader unlocked. Google sold a global model, which is the bootloader unlocked version, and the one I have. The IMEI/MEID number of the global variant begins with 990012 (don't know how many digits are significant). If I was buying it, I'd ask the seller to confirm it was bootloader unlocked.
Glad I could help.

The two P3 options I m considering (Verizon + US Cellular), both are sealed in their original box. According to that post, if the P3 hasn't ever being turned on, which is probably then when bootloader becomes locked
So I wonder if there is a SIM that comes with the phone already and that I have to remove that prior booting the phone. Not sure what he means with "VZW SIM". Is it a different type of SIM e.g. an eSIM??
I know for fact that these phones are CDMA-locked and only GSM is unlocked (but that's what I need anyways)
Does anyone here have any experience from an US Cellular P3 - is the bootloader locked? (the retailer of the phone doesn't seem to know much on such details..)

VZW SIM is just a Verizon SIM. It is probably the standard SIM card, not an eSIM. I would remove the SIM prior to booting, just to be safe. According to one of those posts, WiFi had to be connected before they could unlock the bootloader.

I ll find out soon, I ve ordered the P3 (US cellular stock)
Seller claims that it is sealed in original box. If that's really the case, then the carrier can't have put a SIM into it, right? But what about an eSIM? If they have the eSIM pre-programmed, then I can't possibly avoid booting the phone with it..

Hmmm I think the way it works is that when the phone is produced, for a specific carrier, and the carrier wants it to have a sim, it's put in at the factory. So, I think, sealed with a sim in it, possible.
I don't think us cellular uses e-sims. Double check that but it doesn't look like one of the carriers that's capable of e-sims.
cheers, good luck. I have a vzw coming today, hoping it's new and can unlock as others have... we'll know soon.
Good news! Just got the phone and ... I ve managed to unlock the bootloader!
Exactly same case as described here. No SIM inserted, connected to WIFI, and in Dev Options, turned OEM unlocking to ON!
Then, on the instructions (link by opensense), I ve used adb and the bootloader is now unlocked! I m really chuffed about it
(btw the US Cellular supplied SIM was attached on the box (outside) with a sticker. Box was sealed.
Now, all is left is for me to pick that 'cleaner' Android option I always wanted!
But which one should it be? It's currently running blueline MP1.0(ROW)
Is there any clearer (official) Android ROM that I should switch to instead?
From G services, I would like to keep the Playstore and Maps...

Congratulations. You'll have to define what you mean by the term "cleaner (official)" ROM. Blueline is the only official Google ROM for the Pixel 3. Anything else will be a custom ROM. I have no experience with any of the Pixel custom ROMs, so can't offer any advice on those.
You can disable most of the unwanted Google services in the blueline ROM. I'd recommend keeping the backup service, though.
Blueline MP1.0(ROW) is not a version listed at https://developers.google.com/android/images#blueline Go to Settings, About Phone, and tap Android Version. Check the "Android security update" date. Latest is June 5, 2021. I suspect yours is quite old.
If you want to update to the current blueline version, you have 2 options, OTA or flash a new factory image.
For OTA, go to Settings, System, System update, and follow instructions.
To flash a new factory image, follow the instructions at the link above. To prevent wiping your data when flashing, edit the flash-all.bat or flash-all.sh file, and remove the "-w" from the last line.
I you intend to change ROM's, I wouldn't bother updating.
Good luck.

I think I ll probably stick with the official one then. My current is PQ1A.181105.017.A1 (which is very old as you guessed)
Which means I can jump to Android 10 or 11. From my experience, latest isn't always the best so I might have to keep reading, see if I should jump to a latest build of 10 instead. My emphasis is on stability/security - not new features...
And I want to ensure that the camera is at its best

If security is a concern, you'll want to go to Android 11. 10 has not been updated since August 2020, when Android 11 came out. Also, I believe there have been camera improvements since August 2020, which would not be in the latest Android 10 build.
I have not seen any reports of stability problems with the June 2021 Android 11 update, which has the latest security patches.
I don't know if you can do an OTA update to Android 11 from Android 9. You might have to go from 9 to 10 to 11. You can flash the Android 11 image without going to 10 first.
I intend to do via flashing (whichever version I decide in the end). Not a fan of OTA
Hey all,
I bought a new OnePlus 8 5g T-mobile phone for my wife. She's on the RedPocket annual GMSA/ATT plan. I've stopped the auto OO11 update and I've gone into *#*#4636#*#* and selected "LTE Only" for the connection type (like I did with my old OP6) but it doesn't stick after a reboot.
My real question is:
Since 4G LTE seems to work properly with the T-Mobile stock OS, what are the reasons for converting over to the international version?
Will 4G still work after I update it to OO11.x? I don't mind it having the T-Mobile boot or bloat. I have mostly disabled/uninstalled the apps she doesn't need.
Thanks!!!
The Global version of the ROM can still get OTA updates, and gets them MUCH faster. For example always on display hit global firmware, than hit T-Mobile firmware like 7 months later. Same with Android 11, hitting T-Mobile devices a few months later than global.
T-Mobile also has bloatware that is NON-disable-able, even with adb commands. Unless your rooted, your stuck with it. And some of the package names are cleverly named so you wouldn't assume its anything bad.
You might not care about T-Mobile bloatware, but also remember it has spyware, and even if you don't really "care" about it, every time T-Mobile collects more of your data and pings it back to their servers, thats taking up recources/data on your phone, and by consequence, battery life suffers.
And T-Mobile devices collect A LOT of data, even if your not using them as your mobile provider.
Am I making it sound worse than it is? Probably. Doesn't mean everything I said isn't valid. But yes if you decide to convert to global data will work just fine.

np man, that guide is very complicated for no reason, converting to global is rather simple, but it's a 3 step process. This all assumes you can unlock your bootloader though.
1.) MSM back to stock T-Mobile Android 10 firmware. Specifically this one. This will re-lock your BL if its unlocked.
2.) Let that boot up, go into settings to enable OEM unlocking, and then unlock the bootloader.
3.) Once the bootloader is unlocked, flash THIS global Android 10 ROM via fastboot. There's a flash-all.bat file to make it simple. Once you've finished this step your essentially done, and on global firmware, you just need to...
4.) Boot the phone up and take the OTA update in settings to Android 11. There will be 2 OTAs to take, one FULL OTA to Android 11, than an incremental one to the latest Android 11 build
Optionally afterwards you can re-lock your bootloader, or keep it unlocked and root if that's what you/she wants.
If you're not familiar with MSM tool, and the drivers it needs, check out this thread.
