[Google Pixel 3 Questions & Answers] dcarvil:
What part do you need help with? Rooting the Pixel 3? You'll need an unlockable bootloader, and some carrier specific models cannot be unlocked. Also, be aware unlocking the bootloader will wipe your phone.

See this article for bootloader unlocking instructions, but ignore the TWRP and Magisk parts. TWRP hasn't worked on the Pixel 3 for a couple of years, and the Magisk part is out of date. https://www.xda-developers.com/google-pixel-3-unlock-bootloader-root-magisk/

You'll need the latest Platform Tools from https://developer.android.com/studio/releases/platform-tools

Once the bootloader is unlocked, download Magisk from https://github.com/topjohnwu/Magisk. See Downloads section.

Magisk installation instructions are at https://topjohnwu.github.io/Magisk/install.html. See the "Patching images" section. You'll be patching a boot image, not a recovery image.

Make sure the boot image you use is the correct one for the Android version on your phone. You can get that from https://developers.google.com/android/images. Unzip the file from that site, then unzip the zip within that file. There will be a boot.img file.

Once Magisk is installed, open Termux and run "su -". That puts you at a root prompt.
[Samsung Galaxy S21 Ultra] nitinvaid:
So last week i bought new Oneplus 9Pro was using 7Pro previously

the battery on 9pro is soo worse..... and its not possible for me to charge the phone everytime SOT time is less then 3 hours

heating issues......

if i use camera it work for few min then recording stops getting notification phone heats up....

in the end i am really not satisfied with it.. now i am thinking to switch to Samsung S21 Ultra..

how's the battery life i am from india so ill be getting exynos version.. and can the samsung be easily rootable? any other drawback ?
[Samsung Galaxy S21 Ultra] HAFBeast:
I went from 9 Pro to the S21 Ultra Snapdragon version a few days ago and it is a very nice device so far. I just got so fed up with OnePlus price increases while having awful customer service again and again, across several years but getting worse and worse with my 7 Pro and 9 Pro.

My takeaway.

1. The S21 Ultra display seems smoother in PokeMon go. the 7 Pro and 9 Pro never felt high refresh rate and I was always a bit bummed it wasn't better, but the S21 Ultra seems so much smoother in FPS refresh.

2. The 21 Ultra seems to have battery optimizations that don't ruin other apps. SMS Backup and restore would fail again and again on my 7 Pro and 9 Pro. I would try to restore 60k messages and I wouldn't have any other apps open, but just having my screen timeout and the app would stop and act like I never started it. I tried disabling battery optimizations, but that didn't fix anything. The S21 Ultra powered through these and didn't raise any issues. In fact, I restored about 800k messages (a lot of old backups I wasn't sure if they had restored properly so just making sure), and the S21 ultra powered through. I even opened Pokemon go while doing this.

4. Battery life on the S21 Ultra seem very good. The display is nice and bright and fluid. One noticably difference is the weight of the device. My 21 Ultra feels way bigger and heavier than my 9 Pro. The fingerprint scanner is always pretty fast and accurate. Also, since the screen isn't curved that much, the screen protectors will be easier to apply and not have them peel up or offer poor protection at teh edges.
[Samsung Galaxy S21 Ultra] OPOmaniac:
I also cannot decide between OP9 pro and Galaxy S21 ultra.
[Samsung Galaxy S21 Ultra] Beefheart:
I have the Exynos model.

Battery life is immense, I regularly get to the end of a 16+ hour day with circa 40% battery and having had over 4 hours SOT. Reaching 6 hours+ SOT on these phones is easy.

No issues with heating myself, although I've read others who have. My device with normal user hovers in the high 20s / low 30s degrees C, but that's with UK ambient temps. In India that's bound to be higher. If I record video or use the phone for something intense, it will go up to the high 30s but I think I've only seen it over 40 degrees once when I was benchmarking not long after I first got it in March.

I've rooted mine, it's very easy to do. However, I regretted it, but only because my 8 year old son dropped my phone about a week after I did that and Samsung refused to fix it even on a paid, non-warranty repair thanks to their bulls**t Knox policy. As such I'll never buy another Samsung device but I can't lie even though I'm annoyed with them, this is the best phone I've owned and the best phone out there right now I think. I bought a screen assembly for £280 UK, it's really easy to fit and now the phone is as good as new.
[Samsung Galaxy S21 Ultra] blackhawk:
I'd go with Note 20U, you'll want the SD card slot.

It's also running on the less problematic Android 10.
[Samsung Galaxy S21 Ultra] nitinvaid:
Yes samsung service center personal are like dogs......

They sniff your phone to find out how to say to customer your warranty is void :P
[Samsung Galaxy S21 Ultra] Beefheart:
How did you come to that conclusion? I've got 256gb in my Ultra and I doubt I'll ever get near to filling it and I suspect the same would apply to the vast majority of other users.

Gone are the days were films and music media needed to be held locally, it's almost all stream services now. Vast storage on a phone these days isn't a necessity for the majority, and that will only become more the case as we move forward.
[Samsung Galaxy S21 Ultra] blackhawk:
You can't stream what's not there... and you waste battery. No internet, no music.

With over 200 albums including HDCDs I don't care about online music much other than to sample. This arrangement allows me to fully utilize Poweramp's extensive audio features as well so it sounds better and the playlists/library are embedded and fully backed up.

Zero cloud dependent here.

You need an SD card to use as a data drive for critical data. All my machines are set up with an OS drive and a separate data drive(s).

Android OS's rarely crash until they do. At that point I can do a full restore in under 2 hours with no internet connection. Apps, backup files, everything I need is ready to go. No PC needed either as all the data is already on a .5tb V30 card which is redundantly backed up to a flash drive and hdds just in case.

The data drive also serve as a buffer zone in the case of malware infections. In over 15 years only once did malware breach a data drive; I can't say the same for the OS drives.
[Samsung Galaxy S21 Ultra] Beefheart:
Ah, so you were taking your needs and saying it applied to him. Gotcha.

Personally, I perform a regular Nandroid backup so no matter what happens I have a means of returning it to its previous state.

Even speaking as someone who's worked in IT for 25+ years it sounds like you're using a sledgehammer to crack a nut.
[Samsung Galaxy S21 Ultra] blackhawk:
Allow me to retort *grin*,

I'm saying simply don't buy a very expensive phone that grossly limits your options by having no SD card support.

For years I used my SD card haphazardly like most until I realized I had a 1tb dual drive computer in my hands.

A SD card used correctly increases not only the memory capacity but the speed, redundancy, versatility and security of an Android. If you root you definitely want one...

So yeah, I think you goofed up🤣
[Samsung Galaxy S21 Ultra] Beefheart:
We clearly have different definitions of what constitutes having one's options grossly limited.

Would I choose having an SD card slot over not having one? Yes. Would I describe not having one as being grossly limiting? No. I have enough knowledge of how phones and general technology works to get around any so called limitations the lack of one would bring.

As for the goofed up comment. Odd.
[Samsung Galaxy S21 Ultra] blackhawk:
It's impossible to replace a data drive with up to a terabyte of additional storage. There's no easy workaround to not having instant access to data.

For a high end Samsung you should have this option. That's one reason repeat buyers choose Samsung, options, more then you'll ever likely use but they are there... or should be.

Something the inept marketing people at Samsung chose to ignore.

Actions have consequences Sammy.

I could buy a new flag$hip phone now but I choose not to. Instant karma Sammy...

Meanwhile some of the competition decided they would include SD card slots.

And one of those boasts the new graphene battery technology as well. As Sammy $crews around with their floundering Fold beta hardware some companies are slamming down advanced tech solutions that work.

Ill be getting 512 GB version exynos

one more thing will viper4android works? what are the steps to install viper in samsung
[Samsung Galaxy S21 Ultra] nitinvaid:
Have bought the 21 Ultra 16 GB RAM 512 GB version

i have wireless charger of oneplus... it seems to be not working with this its detecting and then notification charging paused same thing again and again in loop....
[Samsung Galaxy S21 Ultra] enigmaamit:
The S21U will charge with any wireless charger that is Qi certified. If it isn't, it may not charge
[Samsung Galaxy S21 Ultra] Dizzyrul3z:
Nice, top version of SGS21U :) Give up you're thoughts about in comparison to OP9 :)
[Samsung Galaxy S21 Ultra] nitinvaid:
sure i will

i just tried to plug the USB type C cable to 3.5MM headphone cable its not working with S21 ULTRA? :(
[Samsung Galaxy S21 Ultra] nitinvaid:
I am not able to figure it out how to root it.... easy way
[Samsung Galaxy S21 Ultra] chetly968:
It isn't necessary but it's nice to have. I was hesitant to buy the s21 ultra and waited a few months just because of the SD card slot. I can manage to work around not having it but why if you don't have to? I like having my lossless music and all my photos and videos on one card that I can move on to the next phone. Obviously you gotta change with the times now that no phones really have it any more. Though I'm jumping to the Sony Xperia 1 III as soon as it's available.
[Samsung Galaxy S21 Ultra] chetly968:
I have the same issue with the onplus wireless charger and any of my Samsung phones. The Note 20 ultra, z Fold 2 or the s21 ultra. Not sure why that is the case. Luckily I have a bunch of Samsung fast wireless chargers laying around as well.
[Samsung Galaxy S21 Ultra] Beefheart:
As long as you're aware of the consequences, follow the steps in this thread.

https://xdaforums.com/t/recovery-un...s21-ultra-exynos.4240993/page-4#post-85177885

Flashing Magisk in step 7 performs the root.
[Samsung Galaxy S21 Ultra] vegetaleb:
I always rooted my phones since the htc nexus one but the s21u is the 1st I didn't because I couldn't find a solid reason to loose the warranty. Custom Roms are still not offering enough additional stuff, no custom kernel.... What are the reasons that pushed you to root yours?
[Samsung Galaxy S21 Ultra] Beefheart:
I held the same view in all honesty, and held out for a couple of months. But I started to miss having a proper firewall (without having to use VPN), Xprivacy and customisations like Gravitybox.
[Samsung Galaxy S21 Ultra] nitinvaid:
i am aware of the consequences.... was running android since 2012 i think rooted since then till now....

samsung is new for me so asking..

one more thing if i unlocked bootloader and flashed the TWRP will i be able to update the device firmware when new update came? via ODIN?
[Samsung Galaxy S21 Ultra] Beefheart:
Yes. While rooted OTA doesn't work but you can always flash newer firmwares via Odin, and keep your CSC.
[Samsung Galaxy S21 Ultra] nitinvaid:
thanks i have flashed TWRP one last thing does Disable encryption: works?

and how does it helps really? in OP thread it was mentioned

"- Encryption not fully working."
[Samsung Galaxy S21 Ultra] nitinvaid:
Rooted finally........

we dont have in software settings to change accent colors?

my oneplus wireless charger QI enabled is not working with S21 Ultra it detects shows charging then charging paused and stuck in same loop let me know if there is solution for these two things also
[Samsung Galaxy S21 Ultra] enigmaamit:
You can go to Galaxy themes for customisation. Or download GoodLock and get the theme plugin there for granular control over appearance.

BTW, I hope you know rooting is a one way street on Samsung, unlike OnePlus. You can never go back to full stock once rooted, coz Knox is irreversibly tripped. You can unroot but the Knox flag will stay tripped forever. Also, some apps like Samsung Pass, Samsung Pay, etc will no longer work.

Warranty is now void and you can't return to stock to claim warranty if something goes wrong. Just be aware of that.

Aside from the above, phone will function as usual, no major issues. This was very different from my experience on the OnePlus 6, so I stopped myself from rooting. Very expensive risk with the warranty... Maybe I'll do it in a few months...

Enjoy the freedom and extra features rooting brings you. 😀
[Samsung Galaxy S21 Ultra] maxq1:
i too came from a OnePlus device (6T, 3T before that; and mostly been rooting my devices since day 1 even from Froyo days - ye, i'm old ;) ). got the s21 on launch. aside from the huge freebies, i got it under USD 900 (converted). didn't open the box for a couple of weeks as i was thinking of selling it boxed & getting the OP9 later on. based on your comments, good thing i didn't. so thanks for sharing. haven't rooted though seriously thinking about it

if you miss customizing your phone, aside from goodlock, try hex installer too. works like substratum but no root required. turned my phone to a razer-like theme. hex code is 00cc00 for those interested
[Samsung Galaxy S21 Ultra] nitinvaid:
wow didnt know that we can never go back to full stock :P thats bad

i am using substratum to theme the device looking awesome
[Samsung Galaxy S21 Ultra] nitinvaid:
Does screen won't wake when you get any notifications?

Like in OnePlus when you receive any SMS or other notifications

The device screen shows that notifications in AOD display
[Samsung Galaxy S21 Ultra] enigmaamit:
If AOD is set to always on, you'll see notification icons on the AOD.

If you go to notifications under settings and choose 'brief' notification pop-ups, you can set them to show up even when the screen is off. You can also set edge lighting effects here.
[Samsung Galaxy S21 Ultra] nitinvaid:
Mine was set as detailed as I wanted to see mag in details
[Samsung Galaxy S21 Ultra] chungdae:
Can you elaborate on this? Not sure I understand why rooting would give you a proper firewall / protection.

I used to root the S4 and S5 for custom ROMS / kernels but after that Samsung got their act together and one UI is pretty great; I could not find a reason to root after those phones on and lose warranty / Samsung pass / Samsung pay / etc.
[Samsung Galaxy S21 Ultra] Beefheart:
You probably know this and I'm misunderstanding your question, but you can't block internet access to individual apps without root unless you go down the VPN route, with rootless firewall apps like Netguard using Android's single VPN connection to block the access. With root, applications like AFWall+ block internet access to individual apps using IP tables, which allows you to use a commercial VPN like Surfshark etc. whilst having your firewall turned on. This isn't possible without root, it's either the 'firewall' or the VPN.

For me, I don't allow access to any apps unless they rely on it to function. But at the same time I regularly use a commercial VPN. So root for firewall is an important feature for me.
[Samsung Galaxy S21 Ultra] chungdae:
So essentially to stop all internet traffic to all apps including system apps / core apps / etc?
[Samsung Galaxy S21 Ultra] Beefheart:
Yup. For all intents and purposes, there is no difference to the end result between apps that use VPN to block access and apps that use IP tables. But the latter is more reliable, simply because the blocking is passive and doesn't rely on an active VPN connection. Plus the VPN connection being active means there is a hit on battery life, albeit minimal.
[Samsung Galaxy S21 Ultra] nitinvaid:
Been using the device for like 3-4 days no issues every thing is perfect in S21 ULTRA

the device is really far better then OnePlus 9pro

Battery is also like huge difference soo good getting 3-4 hours of SOT no overheating issue nothing.

Only thing is charging is kind of slow it takes around 1.5 hours to fully charge except no complaints
[Samsung Galaxy S21 Ultra] Dizzyrul3z:
What charger you are using? Besides fast charging, S21U also super-fast charges in about 1 hour, but you need a charger with a USB-c port and supports Power Delivery 3.0 / 2.0. I bought Baseus like this one:
[Samsung Galaxy S21 Ultra] nitinvaid:
Samsung Charger 25W I think
[Samsung Galaxy S21 Ultra] Dizzyrul3z:
Hmm I think it is good. Can you have super-fast charging in advanced battery options?
[Samsung Galaxy S21 Ultra] nitinvaid:
Is there any way to record calls? It's not working in my device I am rooted tho I tried cube acr it's not working Its recording my voice but not the other person's voice
[Samsung Galaxy S21 Ultra] marychap:
i too
[Samsung Galaxy S21 Ultra] nitinvaid:
Believe me dont go for 9Pro

S21 Ultra is way much better i was also not samsung FAN since S4 but now one plus is not what we think
[Samsung Galaxy S21 Ultra] mastabog:
I'm late to the party, but I assume you're rooted? If not, what are you using to backup app *data* to SD card?
[Samsung Galaxy S21 Ultra] blackhawk:
Not rooted. The data files are on all the SD card.

It's the data drive. Same as on a dual drive PC.

I use shortcuts set to the homescreen to the SD card as well for quick access.
[Samsung Galaxy S21 Ultra] mastabog:
I'm talking about actual app data that allows me to port it to a new phone without having to reconfigure the app from scratch -- e.g. I found no backup tool or backup method or transfer method that allows me to port both the app and its data+settings for ALL apps.

Using Samsung's Smart Switch does port some apps along with their data+settings but most are ported without data+settings, e.g. banking apps and many others.

Same with Helium.
[Samsung Galaxy S21 Ultra] blackhawk:
Yeah thought that's what you meant, lol rooting voodoo.

Most apps it's not that big a deal. Poweramp... oh god it's the end of the world to lose those settings literally close to a hundred hours (more?) of set up there. Fortunately like many well designed apps it allows for easy backup. My homepage is also a time consuming setup; just saving that is enough if SmartSwitch can.

The other take I have on that is malware, boot loops, a smoke and flames crash and burn would be the cause of any reload. If there any chance of a virus, corrupted files etc dumping all data in apps seems like a good plan.

Full nuke fresh start and all...
[Samsung Galaxy S21 Ultra] sultan.of.swing:
I may be getting rid of my 9 pro and going S21U here soon, I'm on T-Mobile so it will suck not having any custom roms for their version but the 9 pro even with all the custom roms I've flashed still leaves alot to be desired.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] jkmaxfli:
Hello.

I have a few questions about firmware (MIUI) updates on a root device with an unlocked bootloader and stock ROM.

I know that when the bootloader is unlocked and the device is rooted, OTAs updates don't work.

1. Where can I find that a new version of the miui firmware has been released ? Link please.

2. What should the update file look like? size, file type.

3. How is the new firmware updated? method please.

4. So if the above mentioned firmware update can be installed, I ask if everything in the device remains the same, applications, data, etc.?

That's all I wanted to ask, thank you very much.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] hexisg:
Look for xiaomifirmwareupdate on google.

On that site you will find latest firmware files for alioth PocoF3/redmi k40.

You will have a small file ~300mb.You update using TWRP.Just flash the archive and wipe cache.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] jkmaxfli:
I don't have twrp.

I'm following a topic about twrp, it's still an alpha version and from what I've read, it's still fully inoperable and backups and restores not work.

I thought that the firmware update (zip) could flash normally from the system, from the phone environment, where the updates are managed.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] REDOTHELLO:
"still an alpha version and from what I've read, it's still fully inoperable" agree with you
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] hexisg:
It works for firmware update.You cannot update the firmware from within android.

You could use fastboot to flash the images of the firmware one by one .
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] LiNe1771:
Idk what u read.. Backups and restore work perfectly, I just did one backup and restore 2 days ago.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] jkmaxfli:
It is interesting that you can back up and restore.

There were two questions in the topic about whether backup and restore worked and no one was able to answer. It is an official topic and it should be heard there that it can be fully backed up and restored.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Guan Le:
is the 168 hrs waiting time when unlocking the bootloader a luck-based thing or will it always ask you to wait 168 hours?
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] pl1992aw:
Mostly 168 hours.

Old-registered lucky users can have instant unlock, very rare though.

Some bad credit/ unknown reasons Mi-account users can have 360 hours.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Adam Hui:
168 hours was a minimal time for xiaomi to plants something 😁
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] jkmaxfli:
I already have Twrp.

Before the backup, did you check what specifically to make the recovery fully functional?
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Greenspoof:
You can simply download the OTA, install it manually within the official updater (click the three dot when you're in the update app and choose manual install, then select the OTA in your file manager). After update is installed, DO NOT REBOOT DIRECTLY. Go then on magisk, click on install and choose the OTA way. Don't remember the exact word because my Magisk is in french. By this way, Magisk will install himself on the other partition (a or b, depends of your current partition in the moment of the update) so after the OTA, you will keep Magisk. It's possible because Poco f3 has 2 partition, a and b. On some phone, you have only one partition so you can't do this way.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Greenspoof:
By the way, if you don't see the tree dot, tap multiple tile on the miui logo in updater. So you unlock additional update feature
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] jkmaxfli:
But I asked what all needs to be checked in twrp recovery in order to back it up.

Of course, thank you for the above instructions.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Greenspoof:
I know, I just gave you a another way to update
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] jkmaxfli:
a little off topic, right?
[HTC Oxygen] raymondma:
this rom is china mobile offial ,if u want to flash this OS, make sure your phone's spl is hard spl ,hard spl is 7.77.7777

if your oxygen's spl is not 7.77.7777,you can use the dopod310hspl tools to flash it .

it's danger to flash the China Mobile offial ROM if your spl is not hard spl!!!!

your phone may be dead!
