Develop Bugs

Android Upgrade / Root?

Hello,
I've got a Galaxy Tab Pro 8.4 that I bought during the few months when it was the top of the line small tablet from Samsung (before the S series came out). Since it seems clear that Samsung has abandoned it and it won't get an Android update, I want to see what it'll take to upgrade to at least Lollipop. I'm pretty tech savy, but I've never tried to do anything like this with Android and I'm not at all sure where to start.
I've started to read the thread on rooting, but I quickly got a bit lost as I don't understand the terminology.
My goal would be to simply get to stock Lollipop or Marshmallow and have a stable, functional tablet that I don't have to tweak or mess with much. I'd also like to be able to go back if it proves too buggy. Is that feasible, or is rooting plus upgrading pretty much something that will require constant maintenance and tweaking? If it is possible, can someone point me to a how to for complete newbies?

Rooting will not help you upgrade your tablet to Lollipop or Marshmallow as they aren't available for your device. You might want to google "what is rooting" and find out what it does before proceeding.
The only thing you could do to get L or MM is install a custom ROM such as this:

What makes you thin that his device is not have any Third Party ROMs (i.e CyanogenMod)? FYI this is the Tab Pro Fourm, and his Device should damned well be able to get to Lollipop or Marshmallow. e.g. CM12.1, or CM13.
As for rooting which you have to do at the start. Will most likely send him back to SamFirmware's where he'll need to likely first downgrade his Firmware to one that has a rootable exploit. i.e. a 'BOC1' ROM for the T325. (Which is the version I have). Through Odin (Samsung's Android Firmware Windows PC flashing Software). Then run something like the CFRoot App to get root.
NOTE: THIS WILL THROW YOUR KNOX FLAG!
This means that you'll never be able to use Knox services on that Device ever again. It will also throw the Warranty Flag as well Alerting Samsung that the Firmware was tampered with. For the moment (As I gather there is no known way to reset either of these Flags.) Not that this should stop you from installing either CM12.1 Lollipop (Seems to have lost support to) CM13 Marshmallow which is currently on a nightly release.
So the better question to ask is which T32x does Op even have? The T320 (Wi-Fi) The most common, and cheapest version has the greatest support. Where as the T325 (LTE), and T321 (3G) versions seem to be leaving behind. though even these are currently well into Marshmallow, and like with most ROMs there are some small bugs. But, on the whole My Device is more or less working as it should be.

1) I read the OP. He said, "stock Lollipop or Marshmallow."
2) You don't have to root TouchWiz to install a custom ROM. All you have to do is install TWRP, but it doesn't matter because of #1 above.

Well yes if he wanted Stock then he'd be outta luck. But that is not how I read it. I read it that he has accepted the fact that Samsung have left us in the lurch concerning any future updates.
That's how I read it, so the question follows in how to install a Custom ROM. Granted it should be possible to install TWRP v. 3.0.1-0, though Odin, and then the Device appropriate ROM. It should go without saying that the T320, and T325 are not the same Device, even if they are both collectively known as Galaxy Tab Pro's 8.4. As such it would be upnto the owner to know which version he might need.

The problem, is folks really need to stop using the word "stock" as it really doesn't mean jack. Or at the least, means so many different things to different people, as to be basically meaningless. I would take stock to mean, what belongs on the device per the manufacturer, so that would be Kitkat TouchWiz in this case. To others (and probably what the OP is getting at) is a "pure" unskinned Google experience like Nexus. But seeing as Nexus is limited to such a small number of devices, I don't personally feel you can consider that "stock". CM is AOSP based, and at one time considered by many to be close to a pure AOSP experience. But those days are long gone, and there are so many proprietary CM features and apps now, you can't even begin to consider this "stock" by any means.

What you are asking for is CM12 or CM13 (LP or MM) or one of the CM based ROMs. Those are really your only choice when it comes to anything past KK on this device. The CM ROMs are are very stable at this point. You might run into an obscure bug, but to be honest, its less laggy and overall a much better experience than the official Samsung TouchWiz ROM. And if you want to be free of Samsung bloat, CM definitely does that as well.
Tweak or maintain? You don't have to do anything after flashing the ROM, if you don't want to. You can decide to update to newer nightly CM builds from time to time, but that is completely optional. And to be honest, even CM13 is so stable at this point, that the nightly updates don't really change much of anything.
Go back? That's a breeze. Just do a backup in TWRP custom recovery before flashing a ROM, and you can restore to that backup (basically a snapshot of your existing configuration).

Honestly, just searching and reading are your best friend. You'll learn a lot more that way, than folk spoon-feeding you the info. The process isn't really all that hard. There may be a lot of esoteric lingo, but you can easily Google or use the XDA site search to find out what those terms mean. And once you've gone through the process, you'll likely be happy for the learning experience.
XDA is a wealth of information, for those willing to take the time to learn and search. All the answers you want are here in one form or other. Difficult to wade through at first, I'll agree with that. But all of us here had to go through the same thing at one time or other.
Its really hard to help someone when they say is "I'm a newb, tell me how to do this". Make a lot more sense for you to just dive in, then come back here with some specific questions, which we will gladly answer.

it would help to know what version OS you're running and the build #.
I rooted my tablet late last year (bought it in May 2015). Wasn't hard to do after some reading. Knox is still good too...1 yr warranty will be over soon.

Thanks all, I appreciate it. I've been doing some more digging to try to learn what everything means so I might know what I'm talking about. I started with the Lifehacker rooting guide (I can't post links yet, add this to lifehacker dot com: /5789397/the-always-up-to-date-guide-to-rooting-any-android-phone) and their how to flash a ROM guide (/how-to-flash-a-rom-to-your-android-phone-30885281) as well. Let me know if those aren't good places to start. I've also read through the CyanogenMod how to for the 8.4, which seems pretty thorough.
I definitely appreciate the push to search and learn, but it can feel like drinking from a firehose. Most "how to" posts are written assuming the reader knows the terminology and every post I read means Googling a half a dozen terms to understand it. For example, I have no idea what the Knox flag is or why I'd care if it got triggered. I don't care about the warranty flag, I'm past the 1 year mark so it doesn't really matter, right?
When I said "stock" I was referring to stock out of the box Android, not stock Samsung. Stock Samsung means staying with KitKat which I'd rather not do. My phone is a Motorola Droid Turbo, which I think is pretty close to stock Android Lollipop, so that I'm familiar with that.
However, I think I'm seeing that going stock Android isn't necessarily possible, or rather, other ROMs are easier to come by. Cyanogenmod seems to be the most popular and sounds very stable, I'll likely try that.
So, I don't need to root in order to flash a new ROM. What's unclear is do I need to do anything special to make sure I can go back to the out of the box Samsung KK that I have now in case I really screw it up or just don't like it and want to go back? Will the process of installing Cyanogenmod wipe my device (apps, files, accounts, data, etc.?
Any other surprises that a guy who has never done this might want to know before going in?
Thanks again for your patience and help.

I forgot to mention, I've got the wifi model, T-320. It's running 4.4.2, build number KOT49H.T320UEU1AOC1.

Well you have a number of choices for your T320 (WiFi), Sadly nonmof those stock. Since Samsung has never seen fit to ever giving us one. For me the Samsung (e.g. Vender ROMs), were always the 'Stock' ROMs. 'Pure' ROMs (al-la Nexus), are clearly Custom ROMs.
The best, and quickest way to learn how to update from Stock to Custom would be to hit up YouTube for a few short Vids on the subject.

Those aren't bad general guides, to just introduce you to the basic concepts and terms. Just keep in mind that every different Android device has its nuances, which vary by manufacturer and over time (from one device to another - even from the same manufacturer). So you'll be referring back to Tab Pro 8.4 specific guides eventually.

Basically, if you don't know what the Knox flag is, then it probably doesn't matter.
The longer story, Knox is a enterprise mobile solution made by Samsung. If you company doesn't use Knox (and you don't use your device for work), you don't need it. The huge majority of folks will never need Knox or want it.
You're right, that if the warranty is expired, the warranty flag doesn't matter. And honestly, I rooted my device while it still had a valid warranty. I'd rather have a device that I can use how I wish, and install what software I want (especially if Samsung isn't going to support it with updates) and warranty is a secondary concern, at most.

Once you install TWRP custom recovery, you can make a backup of the current Samsung TouchWiz KK ROM; and revert to that if needed or desired.
But honestly, you won't want to go back. CM runs faster and smoother, with no Samsung bloat. You won't want to go back to the crappy TouchWiz ROM, that is 2 generations (Android versions) obsolete.
But it is a good idea to have a backup, in case flashing CM doesn't go right the first time, and the device won't boot.

You will absolute want to wipe user data when installing CM. Not doing so will likely cause major bugs and/or failure to boot. This is the general rule whenever flashing a new ROM. Although for similar ROMs (such as minor CM updates) you can try to keep user data. This is called a "dirty flash".
You can backup a lot of your data before flashing CM:
Apps: After root, you can use the app Titanium Backup (highly recommended) to backup apps and app data
Accounts: Titanium can backup a lot of this stuff, as well. Depends on what you are talking about, specifically.
Files: just move them to SD card or your computer. Or use a cloud solution (there are many)
You should always be backing up your data, anyway, if its important to you.

Same firmware as what I had prior to rooting it.
The cyanogen articles give a good rundown on how to install it. The only thing that I'm not sure about is whether getting the sdcard to be formatted/recognized is still an issue or not.
When last I checked back in Feb. it seemed like that was still unresolved. I have a 64gb card and getting it to be read by CM13 was absolutely critical. So any move to CM13 was postponed.
Running Kitkat is fine for me...after rooting it, I uninstalled/froze a lot of software incl. a lot of Samsung crap that was eating the battery. The battery is my only complaint with the tablet.

The SD card issue on CM13 was solved in early March. It was holding me back as well (stayed on CM12.1) , until I saw it was solved. Now I've been using CM13 for over a month. My 64GB card works great with CM13.

If you flash CM, you'll see its a lot smoother and snappier, especially on the home screens, app drawer, etc.

Thanks all, I plan on biting the bullet some time soon. Too much other stuff on my plate (like car repairs, etc.) so it'll have to wait for a bit. I'll check back in when I do. I'm looking forward to it.

BTW, you can always restore your device to 100% stock (Samsung) by downloading the firmware from sammobile.com/firmwares and flashing it using Odin. If you get into trouble, this will help get you back out.
But since flashing CM13 nightlies is relatively easy, I don't think you'll have any serious trouble, just the normal learning curve.
I've had my SM-T320 on Cyanogenmod since the day after I bought it in 2014 and never looked back :good:

I'm trying to load the latest CM 13.0 nightly this morning and running into issues.
I'm following the install instructions on the CM website and the loading of a custom recovery is failing at step 7. I get the start of the blue bar on my tablet, but I get this error in the command prompt:
Downloading device's PIT file...
ERROR: Failed to send request to end PIT file transfer!
ERROR: Failed to download PIT file!
Ending session...
ERROR: Failed to send end session packet!
Releasing device interface...​
I've tried twice with the the factory cable and a third time with an alternate cable same result.
How do I fix that?

I should mention that I'm working on a Windows 10 computer.

Does rooting require you to wipe your phone? (and other basic rooting questions)

The last time I rooted a phone was with a GS3 to install CyanogenMod. I've recently picked up a Pixel 2 XL, and I had some fairly noob-esque questions:
1. Do I have to wipe my phone to root it? That is, there is no "in-place" rooting?
1a. Are there any good methods to make a full backup *without* root before rooting it, and then restore it after I root?
2. Does rooting my phone make future OS updates more difficult/impossible? Ie: Will I still get OS updates, or will I have unroot my phone to get updates, then reroot it, possibly wiping everything?
3. What's the best method to go about doing this now? Googling around, and looking around here, I see a few different, but similar methods. I also see references to a "critical unlock," but no matter how many guides I read, I don't understand it. I'm starting to feel like I don't understand enough anymore to root my phone :-/
I really want to just be able to get back hosts-file based ad blocking again, and maybe a few other tweaks.

1, 1a: Go here and start reading, if you haven't already done so. To root requires unlocking the bootloader, which will cause the device to be wiped. It's best not to put anything important on the device until afterward.
2: OTAs must be applied manually. See the link I provided for instructions.
3: The P2XL is apparently unique in having two unlock commands. The non-critical unlock unlocks the bootloader while still providing some protection. The critical unlock strips all protections from the bootloader. To be on the safe side, execute both commands as mentioned in the link I provided.

Does that require re-wiping the device? Will I still get notified of updates, or will I have to keep track of new releases on my own?

The linked thread specifically says that OTAs do not require a device wipe. You should still get notifications.

Some have "dirty flashed" P over oreo with removing the -w flag from flash-all.bat script in the P factory image with mixed results. Your best bet is to clean flash the P build with fastboot to avoid any potential problems. However, yes, it will wipe your phone

Drat. Restoring apps and settings is far less painful than it used to be, but re-enabling all my 2FA is a pain in the ass.
If I do a clean flash of P, will I be able to upgrade P as new releases come out, or will I have to clean flash every time there's a new release, until it goes public?

Yes you would be able to upgrade to the beta releases. However, you'd likely have to go back to Oreo, which would require a full wipe and clean flash, then upgrade to the betas. The first beta release is due out this month according to all the scuttlebutt I've read, so I think your best bet is just to wait a little longer.

Simple root and flash question

Hi guys,
Just moved form unlocked and rooted Mi Max 2, the boot loader of my Mi Max 3 is unlocked running Global stable 10.3.1.0 stable (PEDMIXM). Question: can I just install official TWRP (https://twrp.me/xiaomi/xiaomimimax3.html) and flash modded Global from https://mi-globe.com/ without any risk. Just hate to brick it
Seems like an easy way to root and mod.
Thanks in advance

Hmm, well hopefully someone more experienced will answer, but...
Globe ROM is based on miui.eu, who themselves remove ARB (anti roll back), at least as far as I'm aware. This shouldn't matter though, I'm assuming, as you'll be flashing newer firmware/vendor etc than what's on your device currently. See here for more info
As for TWRP, I'm not sure, I'm currently awaiting delivery of my mi max 3 so cannot say much more on the subject, but have been reading a bit about it, plus I have other Xiaomi devices that have run Globe ROM in the past. Sorry if it's all a bit vague, like I say, hopefully someone more experienced will step in and assist you. But that should give you a bit of assistance and some further reading!!
Also see here for further info on ARB of your ROM

Thanks for the detailed reply. Yes ARB is probably the root of my worries. Flashed the hell out of my Mi Max 2 without issues but as I said I'd hate to brick it so soon. I'll update the thread with my progress.
Again thanks so much for the info.:good:

For me twrp only worked once and only once and then i bricked it. After that i bricked and can never go back by fastboot TWRP again. Now every time i boot to TWRP, it goes to black screen with backlight lit.
What i don't get is how other devices like Redmi 5 Note Pro, Mi 8 can get twrp to work if they are also on the list like Mi Max 3 for the recent Anti Rollback.

I ALSO have the same question ,
I didnt unlock the bootloader yet but i want first to know is it safe to root this device i read many users saying the antiroll **** is causing bricking the device .
If anyone can tell us a detailed guideline or steps to how to root the device for the average non advanced users like us ,

the following:
to be on the safe side use fastboot boot recovery-image-name do your stuff and boot via stock recovery when you don't need twrp specifically
like this you can avoid issues with encryption
if you don't want that you can make sure that you get a version of twrp that has no issues with decryption.
if you upgrade API version, i.e. Oreo > PIE, only do that if you don't intend to roll back to oreo
unlocking the bootloader and rooting are straight forward and no different than for any other device, what has basically changed recently is
A/B partitioning as well as recoveries mostly being in boot (no separate recovery partition for most devices) and that encryption scheme
has changed in a way that twrp without tweaks (original) has issues with decryption.
i use other than this A/B devices like OP6, OP6T and one simply has to be careful and not just flash away, thins got less forgiving
but work nevertheless once executed correctly.
if you want TWRP permanently you'd have to flash the twrp zip via fastboot boot twrp.img or fastboot flash twrp.img (not mandatory) boot into twrp if you flashed and flash twrp.zip, boot into recovery first and directly and there you go until you flash a new system things are quite stable if you choose your variant of twrp carefully.

Could someone with a rooted Mi 10T Lite try this?

Hello,
I have recently entered the world of Xiaomi after a history with Sony Devices (Xperia, Xperia SP, Xperia Z3). I'm so far delighted with the Mi 10T Lite, it's feature rich and blazingly fast. However, I miss one feature I had installed on my SP and Z3 that made their batteries live extra long. It's this:
Battery Charge Limit [ROOT] - Apps on Google Play
Stop charging at desired level to preserve battery health for most devices!
play.google.com
With this tool, you can essentially leave your device permanently on the charger and it will stay within the limits you have set. I used to have it set to 71-80%. So when the charge dropped to 70% it started charging, until reaching 80%. I therefore balanced keeping the battery charged for short intervals and at a sweet spot for its health, with having enough charge in case I wanted to grab my phone and leave the house. I really love this app.
The problem is, it requires root privileges.
I understand that rooting my Xiaomi is not particularly hard, but since it is a new device I would not want to void its warranty. It's possible that some defect shows up and I am left without a warranty. It would be a particularly big bummer if I discovered I rooted the device only to see that the app does not work properly with it.
So, could someone with a rooted device try out this fantastic app and let me know if it works? You might end up with a battery life extender you never knew existed!
Many thanks,
Yanni
Athens/Greece

Friendly bump! Could somebody try this nifty app for battery life optimization on their rooted 10T Lite? Let me know if it works so I can go ahead with arcane rooting magick, hehe.

I have been using it for the last two years. It is a great app.
It does work fine on the mi10t lite, you just need to change the control file from default to "input_suspend" pixel2/xiaomi mi6. After that the limit is respected. Another alternative is a magisk muddle called "Advanced Charging Controller" it is more technical than bcl.

It does work fine on the mi10t lite, you just need to change the control file from default to "input_suspend" pixel2/xiaomi mi6. After that the limit is respected. Another alternative is a magisk muddle called "Advanced Charging Controller" it is more technical than bcl.

Thank you! Both for the confirmation and also the control file's location.
I think I'll be rooting my device, using magisk. Briefly browsing a couple of guides, I guess it won't be very involved. Besides voiding warranty I'll be losing OTA firmware updates. I presume I will have the option to manually updating by flashing a new official ROM.

Just FYI - you should not void the warranty (at least in Europe - https://www.piana.eu/root/) and OTA updates will arrive normally. You will need to restore stock boot image from Magisk manager before installing OTA and then re-root the phone afterwards, but that's the only complication.

Thanks for the link. Besides the EU statutory warranty, a quick search reveals that the company itself allows rooting without voiding your warranty. So I'm a happy camper I guess.

Guys, please, if anyone can upload the .xqcn file generated by the backup in QPST, thank you. It has to be a Mi10T Lite Global or EEA.

You do not need to ask in every unrelated topic. I guess that no one has the file and/or no one wants to share his IMEI publicly.

In fact, there is the issue of IMEI. I wanted the file to go through my device and see how it would behave, taking the risks. Unfortunately the XDA community was once more collaborative.

Maybe if you provide step by step guide how to extract xqcn file and remove sensitive information from it before uploading to the internet, someone will be willing to do it.
In each case, we are heavily offtopic here.

Hello, I thought of hijacking my own thread again.
After painfully waiting for a week (go Xiaomi!), I unlocked my bootloader, and got an instant factory reset with all my data gone (again, go Xiaomi! I didn't expect that).
But now all is unlocked and I am left with the task of rooting my device. I think I 'll use Magisk. From what I understand I need a boot.img file to patch and then flash. Thinking I 'd like to keep my current ROM, I looked around for a full ROM image to get the boot.img file. But I couldn't find it.
My current ROM is MIUI Global 12.0.5.0 (QJSEUVF), which like I said, I could not find anywhere. It must be an early 12.0.5 ROM used on the first phones shipped. I have two questions:
a) Is it possible to somehow extract the boot.img file from the running phone?
b) If not, and if I can't find the installed ROM zip, what ROM zip would you pick to stay as close as possible to the one I have now? The reason I want this is that the phone works pretty damn fine up to now, and I see reports of problems after major upgrades, like version 12.5.
Any info much appreciated!
Best Wishes,

Bootloader unlocking always results in a factory reset (unless vendor seriously screwed up), it's standard security feature of Android since..like pretty much forever.
If you do not have boot.img at hand, the most easy solution is probably to hot boot TWRP ("fastboot boot twrp.img") and flash Magisk from there. Also it might be a good idea to reflash your phone with normal global version which is already available for download, QJSEUVF sounds like Vodafone version, I would certainly get rid of it and replace it with QJSEUXM.

I should have figured out what VF means. I think I will take the straightforward way and use QJSEUXM which I have found readily available. Thanks!

Question Poco f3 bootloader unlock + custom rom

Hi everyone, I'm new to the community and I had few previous experiences with phone modding so I'm here to ask you some support. I'd like to unlock bootloader, root and maybe install a custom rom o just xiaomi.eu rom but I don't want to brick my phone. I don't know what disadvantages i get other than losing the warranty( i read something about banking apps and netflix). If someone could guide me or link to some detailed guide I'll be very grateful.
The first question about bootloader is do i lose data when i start the process of unlocking the first time and should pop up the error of 160hours? or i lose data only in the second "try" after 1 week?
As said i have a poco f3 8-256 if could be useful.

You won't lose data, at least in my case but just make a backup to be safe.
You can start here:
You can look at his other videos too about Poco F3. They are very helpful to me and it is in English.
I personally prefer xiaomi.eu ROM 12.5.19 gives me 700k AnTuTu, google apps, miui cam, good battery life, good gaming experience, game turbo, and debloated miui which is optimized for the phone.

Yes correct, your phone will only do a Factory Reset after the "2nd try", aka. when the bootloader gets actually unlocked.
On the 1st try, nothing happens with your phone, it'll just ask Xiaomi's servers to allow your Xiaomi Account to unlock the BL.
Munchy's videos (the video above that LynnnXDA linked) are a good starting point for info.
To give you useful info along the way, the other day I made a comment about the disadvantages of Unlocking your bootloader in this thread, I will copy&paste it here:
If you unlock your bootloader, you must be aware of the downsides. Some apps won't work (at least not without a workaround), like Banking apps, Netflix, Super Mario Kart, Google Pay.
That's cuz Google's SafetyNet API reports to those apps that the Security-Status of your phone is "Fail", because of the unlocked bootloader.
You can hide it with Custom ROMs that specifically list "SafetyNet passed" or by using Magisk Root with a SafetyNet Fix Module. Or Both idk whatever.
I use Xiaomi.eu Custom ROM on Android 12 with Magisk Root. Everything works, but this stupid cat & mouse game with Google and Android Modders definitely sucks.

I also made another comment about the risk of bricking your phone when flashing a ROM, in this thread:
Critical partitions are being modified in the Flashing-process.
There is no protection.
If your phone shuts down during the Flashing-process, your phone can get bricked (black screen) and you can't even boot Fastboot & Recovery anymore. I know this. I have experience.
You must ensure that you have enough Battery (I recommend 75% Battery at least), that the USB connection is stable (will not disconnect randomly), and that your PC won't crash/shut down.
IF IT HAPPENS, that the Flashing-process errors out, DON'T REBOOT THE PHONE. If you do so, you won't be able to enter Fastboot anymore. You must stay in Fastboot. Just reconnect USB, and try again to Flash. Just don't reboot the phone.
Sorry for fear-mongering, but this is definitely dangerous and not to be taken lightly.

Despite the disadvantages (which might increase, because of Google fighting against it), there are some nice advantages, like being on the cutting edge ROMs with the latest updates, freedom, Access to system files, System-backup/restore, Call Recording (which may otherwise not be available for you), Cool Magisk Modules, Mods and other things...

The best drivers are included in Mi Flash, under the menu "Driver".
Before installing the drivers, I recommend starting Windows with Driver Signature Enforcement disabled.
Otherwise not all drivers get installed, because a few are not signed (They are safe to install though).
To temporarily start Windows with Driver Signature Enforcement disabled:
1. Hold SHIFT while clicking the Restart-Button
Windows automatically boots into Advanced Startup Options
2. Click "Troubleshoot" > "Advanced options" > "Startup Settings" > Restart
Windows boots into Startup Settings
3. Click 7 for "Disable driver signature enforcement"
Then when you're in Windows, you can install the drivers from Mi Flash.

Hi everyone, tomorrow i will unlock my bootloader and during this days I looked for some custom roms. First of all I want to ask you which are advantages and disadvantages of rooting the phone, I read about safetynet problem, and also some custom roms that are compatible with safetynet.

Hi All, what is best stable EU 12.5 rom for POCO F3 best better battery life?

Hi All, is it every time request unlock bootloader from xiaomi.com have to wait a week 7 days ??

@coolkillermax Yes, you have to wait.
