Can I root my S9+ in July 2021, without having the battery max out at 80%? The phone is an ATT S9+ (SM-G965U) on Android “Q” aka “10”, with Security Patch: March 1, 2021, Knox ver. 3.4.1, Kernel ver. 4.9.186-19871035. And although it's AT&T branded, I plan to use it on the Telus network in Canada.
I’m reading conflicting information as to how doable this is, so it’s kinda confusing. One source says it may be possible if you’re on Android 8, but after root, the battery caps at 80%.
Don’t want to bother with it, if my battery will be affected, or if there’s a chance of bootlooping.
Unfortunately, the method results in 80% battery cap
Idk if you can bypass that unfortunately nothing can be done as of now.

So I learned the hard way that you can't have it all.
I travel for work quite a bit and I was in the Middle East working when my Verizon S7 Edge started to have problems. I looked for a replacement in Dubai and was happy to find the S9+ at a reasonable price and with the 256GB option (which I wasn't finding in the US). I popped in my Verizon sim and life was good.
Then I returned to the US and. nothing. worked. I had forgotten that Verizon was strictly CDMA in the US and this phone had no CDMA radio.
I also was noticing that the samsung pay app was locked to the UAE version which was annoying but not a huge issue...I couldn't add American Express credit card which may or may not have been due to that region setting.
So in order to actually get service I switched to T-Mobile and have had decent data rates. However the phone doesn't use volte or wifi calling which is very bad since where I am staying is somewhat of a dead spot for mobile coverage. I basically can't receive phone calls here and making a call requires me to wait about a minute for the phone to figure out what protocol to connect to (dowleveling to either a 3g or H to actually connect and dial).
My initial research tells me that I don't want to root the phone and lose all ability to use samsung pay, but I would love to do as much as I can to the phone to get it working as best as possible.
Can someone chime in here to let me know what's possible? I don't want to experiment too much, and it's been rare over the years for me to keep up with all the root/firmware/rom etc. that has become available. My last real era of rooting phones was many years ago with iPhone and even then it was a lot to keep up with.
thanks in advance!
bump.
Anyone?
I had the same issue. I ended up rooting to get TMobile volte/wifi-calling. Also, by rooting you can also use Verizon Wireless; however, only with LTE.
You could use Google Pay lol.
Furthermore, I suck at giving reasons, but that's what I did.
Don't quote me on this, but from what I understand, you can use the patched ODIN and flash the firmware's CSC outside of it's region and change it to XAA. There is also a guide to changing CSC without root that may work as well.
From what I understand, the G965F is unable to load the XAA csc without root since it is only for the Snapdragon version
I ended up using Tekhd's tmobile detonator after I bricked my G965F/DS atleast 3 times. It works great now.
The way to change csc without root is via a combination rom and using Realterm. Using TMB CSC on a global G965F/DS ROM will end up in a PUK code lock. I tried ALL the US CSC on my G965F to confirm this.
Just received 10.0.39.hd61cb .. just installed haven't tested yet

Do we need the new kind of SIM for this to work? I've seen people in other threads talk about the R15

I already had the r15 sim seems to be working good. Dont know about older sims. Seen people was having problems with samsung 5g devices with older sims.
R15 sim is needed for voice to connect, in nr only mode I get no voice service with the old sim
5G NR working here with .39 and R15 sim. Well, I should say 5G NR data is working. When set to NR only in #*#*4636#*#* and wifi off, I'm not able to make voice calls. (Before .39 and R15 SIm, setting it to NR only resulted in zero service. So 5G NR is definitely working!)
It's not the new R15 sim causing the problem. Without the R15 sim, one can't even connect to SA 5G for data.
Is that just me or is that the same for everyone? Does Vo5GNR not exist yet? Or only in some areas?
Edit: According to this: https://www.telecompetitor.com/understanding-t-mobile-standalone-5g-technology-what-is-vonr-vinr/
it says TMobile does support VoNR but in addition, supports "the first low-band standalone (SA) 5G voice call using evolved packet system (EPS) fallback to VoLTE". Is it possible they haven't deployed VoNR yet? Can someone set to NR only with wiif off and try making a call?
edit2: After some further reading, the X55 modem doesn't support VoNR. The upcoming X60 will. So there isn't a single phone on the market currently that supports VoNR. I know in about phone it shows NR for voice and data, but that's not accurate. https://www.androidauthority.com/qualcomm-snapdragon-x60-5g-1084417/ https://www.qualcomm.com/news/relea...hird-generation-5g-modem-rf-system-enhance-5g
However, I'd still like someone to confirm my findings.
Also probably the reason the NR only mode is hidden in the debug menu instead of a regular setting.
Speedtest results in NR only mode are disappointing slow. Slower than NSA mode. And NSA is slower than plain old LTE at my house, which has been pretty consistent since I bought this phone.
On the plus side, LTE service in my area has actually gotten faster over the 6 months I've had this phone, so that's nice.

Speed results at my home: LTE is approx 75/12mbps constant
NSA 5G low-band: is approx 120/20 (but can drop to 10/5 at times, even before SA mode became available)
SA 5G low-band: approx 5/5mbps
If set to auto settings, it'll stay on 5G NSA 95% of the time. SA 5G definitely isn't ready for primetime yet lol.
Future 5G low-band updates (currently in progress across the US) and especially mid-band (n41, 2500MHz) availability will greatly increase speeds to 300+mbps (already available in 200+ cities and T-Mobile says 1000+ cities by end of 2020 -- most are small cities in only a handful of states as of now). Haven't had a chance to test it personally.
I ran a bunch of speedtests today, and discovered that 5G NSA was performing better than ever (even faster than plain LTE) while 5G SA was extremely disappointing.
Anyone found a hidden setting or app that can _disable_ NR SA?
The speedtests results tell me I'm better off without it for the time being, at least until TMobile fine tunes and works out the initial rollout kinks.

Don't think you can disable SA 5G, but my phone stays on NSA 5G the vast majority of the time. I'm assuming TMobile set it that way on purpose knowing that their 5G SA network is very slow at the moment.
Is there a manual way to install this? I've got an unlocked bootloader, I was rooted but I couldn't get this update to install, I keep getting "Installation problem" and no real details. So I restored my original boot.img which I'd backed up. So now my phone isn't rooted and yet I'm still encountering the same exact error. The only thing I can think of is the unlocked bootloader, which sucks. I'll have to jump through some serious hoops to go back to 100% stock (because the userdata will be lost). Hoping somebody has found a way to just manually flash this somehow.

No way to manually flash any OTA or updates on this phone. Either your boot partition isn't stock, your recovery partition isn't stock, your reserve partition is missing or is the wrong version (if you never or incorrectly restored it after you first unlocked the bootloader), or any other system partition (system, vendor, product, odm -- all which are contained in super.img thanks to Android 10) isn't stock. If it's boot or recovery or reserve you can fix. If it's anything else, your only option is to run the latest MSM tool to get back to stock (wiping all data in the process), followed by unlocking again, running the correct version of the tool to restore reserve.img, and go from there.
If you simply unlocked the bootloader and never read the thread about restoring your reserve partition, that's likely your problem since you already restored boot to stock. And an easy fix.
And I can't say this enough, BACK UP YOUR PERSIST PARTITION NOW! It's unique to your specific phone and SHOULD never ever be altered in any way. OTAs don't touch it. It won't prevent you from taking OTAs if you corrupt it, which is very likely on this phone sooner or later with the bootloader unlocked, but you will wind up with a broken fingerprint sensor/reader (which if you are lucky can be fixed yourself without RMA, but it's much, much easier just to make a backup to begin with).
Edit: The 10.0.39 version of the MSM tool came out, so you can use that to restore/update, but you'll lose all data in the process, and have to unlock the bootloader again and then restore/fix your reserve partition (so that future OTA updates will work) again.
Since updating, I've noticed that Google Pay no longer works. Also, with the new Majisk UI, there is no more MajiskHide list. Any one else notice this?

The new version of Magisk comes with MagiskHide disabled by default if you do a fresh install of Magisk. You need to go into settings in the Magisk app and enable it. Reboot. Problem solved. And the MagiskHide list will reappear too

Thank you, all set now. Still not digging the new UI of Majisk though.
With the impending 3G network shutdowns by AT&T (on Feburary 2022) and T-Mobile (already done in January 2021; Sprint network will in Janurary 2022), I'm badly in need of another option. My current LG Nexus 5 (International version) won't enable me to survive these shutdowns, as it lacks the full LTE band support for the United States carriers.
After searching for another phone model with the criteria of removable battery, USB-C and unlockable bootloader, I settled on the following listing for a LG G5 (RS988): https://www.ebay.com/itm/LG-G5-RS98...M-Unlocked-Smartphone-8-10-18174/164707426461
The main thing I care about here is whether I can get VoLTE support at all, so that I can continue receiving cellular service beyond 2021. I currently use Cricket, an MVNO which uses AT&T as its network. Unfortunately, AT&T has a whitelist of devices that are allowed to use VoLTE on their network: https://www.att.com/ecms/dam/att/consumer/help/pdf/Devices-Working-on-ATT-Network.pdf. They do list the AT&T version of the LG G5 (H820), but it is bootloader locked. If I cannot use get this phone to work on AT&T, I will have no choice but to switch to T-Mobile or an MVNO using its network, such as MetroPCS. They have already shutdown their main 3G network, and also require VoLTE, but at least they don't have a whitelist that only allows me to use certain devices.
Looking at the custom ROMs, including LineageOS, it seems that none of them have VoLTE support, which is critical for me if I decide to switch to T-Mobile or one of their MNVOs. I could also see if there are any ROMs based on the stock ROM. If all else fails, I can resort to using the stock ROM/OS and then root it. However, this opens up another problem: I cannot tell if there exists a stock Android 8.1 Oreo ROM for the RS988; everything I read so far seems to indicate that I will only get up to Android 7.1 Nougat on this particular model.
As I have accepted an offer for $55 down from $64.99 in the above listing, and cannot decline to buy it, changing to another phone model is no longer an option for me in terms of keeping my cellular service working. Since I will be stuck with this RS988 for the next few years, can someone tell me what is the current situation about VoLTE support, whether for AT&T or T-Mobile, and which ROM I should stick on to gain this support? Losing my cellular service in 2022 is not going to end well for me if it does happen.

DONT use MetroPCS I was with 'em for years but they have changed there policy's not like now. Simplemobile costs the same...

I'm up against the same VoLTE wall (had a Blackberry Passport 4 years) and right now only finding VoLTE in Nougat ROM... TBH, I don't want Oreo b/c of that "A-B parition" buisness

I feel ya bro, right now I'm on a "burner" (LG-Stylo, for big screen) due to this concern. Did you ever find a ROM for RS988 with VoLTE?

You came in a tad too late; by now, I ended up getting an entirely newer phone, a Motorola Moto G Power (2020) via Google Fi bill credit. Though its battery is not meant to be user-replaceable, at least it has support for VoLTE out of the box, which is what I care about more.
I grabbed this phone (free) from Metro about 7 months ago. I was able to use their app to "unlock" the phone after 6 months. I'm unclear about what the official "unlock" will actually allow me to do with the phone. I haven't bothered to try to load a ROM or even root it yet--is this possible? The toggle to unlock the bootloader now seems to work, but I haven't bothered (yet). FWIW, I've rooted all my Nexus, Pixel, and OnePlus devices for the past decade (as well as loaded ROMs), but this is the first phone I've purchased that was carrier locked and I don't know what all that entailed. I honestly don't even know if the Metro variant is the same (as in bands, etc.) as the vanilla North American version or not. Hell, I don't even know what other carriers it might work with. I know I sound like an idiot newbie, and I guess I am with this phone. I've actually google'd quite a bit, but I just can't find much information regarding the Metro version of the phone.
Erm... what do you WANT to do with it?
Backup gets easier as root. Some don't care and real-time stream to the cloud.
Some are paranoid of what certain large companies *cough* Google *cough* might install on your phone in the middle of the night without telling you... unlocked bootloader lets you go to an OS build from AOSP or its ilk that allow you to see source code (if you are really, really, bored enough to check it all).
Some want to kill bloat (rather than just disable it).
Some may want to keep their phones for well after they are supported officially, with an OS like Lineage, or eOS (this not so much for Nord with a fixed battery, although I suppose you can replace it if you are determined enough).
Likewise, I have old phones I've turned into MP3 players for the kids- strip all the "phone" stuff and prevent connections to Internet/cell (eliminates the security threat of an old OS) and simply sideload AIMP, VLC, or whatever your favorite player is.
GSMArena has a very easily navigable feature list, that will show for some phones the different bands each supports- and you can compare to what your preferred carrier uses. USUALLY - but not always- there is an "international" version and a "US" Version. Verizon sometimes gets their own model with/for CDMA bands, but most support all the GSM Carriers and their resellers. If you are sim unlocked, you should be able to use them on any carrier, YMMV.
T-Mobile and Metro usually don't screw around with the cellular bands of the phones they sell, so the Metro/T-Mobile N10 does support the same bands as the factory unlocked version.
And you can start off by flashing the unbranded firmware onto the phone if you don't want the Metro junk and boot animation.
I purchased this device in July of 2017. ABSOLUTELY LOVE IT.
Over the years it has had both T-Mobile and AT&T Sims and the only difference was that on T-Mobile, it could not be on a phone call and make/receive texts.
Feb 22, 2022, the day AT&A shutdown 3G in the USA, it stopped making phone calls. It still texts.
Got hold of Samsung Support and according to them, this device should still be making phone calls, BUT, they think it is someplace except the USA.
It will work as a Google Voice Phone (probably will do other VOIP things also but I have not tried) over WIFI.
Is this device actually effectively now simply a SIM card enabled Tablet that will text via a phone number?
a. Would it text it I simply buy a "Tablet Plan"?
Is there a way to get native phone to work again?
Thanks.
P.S. Thought occurred to me that those who might be able to help with this might be helped with some more specific information on the device,
