rooted Huawei P10 and update OTA

Hello everybody.
I'm a new member in this very helpful forum because I need to ask rather than read already existing threads that didn't help that much...
First of all, I'm sorry for my English. My mother tongue is German.
I'm a very happy owner of a unlocked and rooted VTR-L09C432B150.
One week ago, I received the message that OTA 162 is available now.
I know, the forum is overfilled with questions about that problem but anyway, I still don't feel very well advised...
I figured out, that there are many ways to solve the problem. Let me tell you the ways I know and where I stuck.
Redlotus is a way but it seems that many users were not successful with installing a new firmware.
Firmware Finder is the other chance but actually it seems to be not working for P10 Devices because nobody knows the correct partitions that are needed?
I'm not very experienced about modding and all these ways seem to be very riskfull to brick my P10.
How did you update your phone in the easiest way?
I would also relock and flash the stock recovery before installing the OTA and get backto unlocked bootloader and TWRP after. Very annoying but it is OK. The functionality to back up system data (settings etc) is given by System app (save/restore), right?
May I use the eRecovery function to get back to stock recovery with unlocked bootloader? Didn't find any answer and don't want to do heavy mistakes.
Ok a lot of questions and much to explain. Sorry for that but I'm sure you can help me patiently.
Thanks.

Help needed with new phone

Hello
Just got myself a new piece today. I'm afraid to do anything wrong and afraid to use without installing a new ROM myself.
I have read on different forums that when you buy a global version they are often infested with malware and you have to do af fastboot update to remove it all.
I haven't powered the device up yet because I want to do things right the first time.
My intention is to have the newest official stable global rom on the phone. I just not sure which step i need to take.
If a helpful soul could advice me I would really really appriciate that I have found several guide but I need to know the exact right steps. It is okay if you link to a step by step guide.
Here are links that I would go with, but I'm not sure if I need to unlock and if I have to wait for 2 weeks to be approved or if there is a quicker way

Hello welcome to the yard. ?
If you're still afraid of beginning with all these great guides, better do not power on though.
Sent from my lithium using XDA Labs

Well eventually I will have to power it on - won't I
I'm not affraid to use these guides or some other detailed step by step procedure. I'm just a little confused about the order and if these guides can be used if I want newest official global stabel ROM. I guess It is more the steps than what you do in the steps - hope it makes sense
Charlie Kilo

You'll have to get it powered up and registered. Xiaomi impose a 3 day embargo on you where you cannot unlock the bootloader, I'd at least get that timer ticking away and then apply to unlock it asap.
Then you need to install TWRP. I recommend searching for the Mr Raine's version.
Pick a ROM and then off you go!

Think they're trying to scare you, just look about phone check ROM number to see if it matches 1 of Xiaomi official ROM. I had vendor ROM and my house hasn't been stolen, just don't turn you're data on.

A fastboot update wouldn't remove anything that's on the device. As it sounds, it would just perform an update.
As others stated, you should get it powered on & start the unlock process through Xiaomi. You don't need to sign into your Google account, so the only thing they would have access to is the Xiaomi account you register with.
After you are able to unlock the device, get a custom recovery (TWRP) installed. You may need to try a few different ones, i.e.: The "official" one doesn't have the touchscreen when booted into it.
From there, choose a ROM, flash, & you're good to go.

Thanks for the help so far and good advices.
Update of the situation is that I powered the beauty up. I could see that it took me through the entire setup phase from the beginning like it is normal for a brand new and untouched phone. Shortly after it was updated twice via OTA and is now on the newest official global ROM.
Everything is working perfect and I am extremely happy with the phone.
Two days ago I requested Xiaomi to unlock the bootloader as I would like to root the phone.

Let me know how it goes when you do, & what you end up flashing. I'm done the latest MIUI Beta & now the Pixel Experience 8.1 ROM, & I keep losing voice call server. Looks like I can still text, but no outgoing or incoming calls. I'm running on Project Fi too. With all these issues, I'm considering a switch to the Essential Phone. Arriving today for me to test out.

Canadian P20 Pro version CLT-L04, Questions about Magisk and bootloader unlock

Hi! I picked up my Canadian P20 Pro last week and couldn't be happier. It's been many years since I've owned a rootable device though and a lot has changed! I've done my best to read through all the guides for rooting the P20 Pro and it's only lead to further confusion as there seem to be many recent advancements. There seem to be a lot of different versions of this phone too. So I have some questions I'm hoping someone can answer easily! Let's assume my bootloader is already unlocked....
1) there's a really great guide on rooting the P20 Pro using All In One tool. But that requires flashing TWRP to achieve root using Magisk. I do not require TWRP as I only want root and do not wish to flash any roms.
a) is there a way to root with Magisk and NOT flash TWRP? I can't seem to find a straight answer on this...
b) failing that, can TWRP safely be removed and keep root afterward?
2) after unlocking the bootloader I was welcomed by a terrifyingly orange warning about my now 'unsafe' phone. I've read mixed things on hiding this. Is there currently a way to hide it?
3) how does the process work for OTA updates on an unlocked bootloader assuming there is no TWRP? I've read differing opinions on the necessity of flashing a no_check.img to the ramdisk and have no understanding of the new security checks on these phones. Can I run risk of bricking my phone through an automated update?
Ultimately I'm scared of forgetting TWRP is on my phone and accepting an update that'll brick it. Any information is welcome as are similar questions!

I am also curious if there is a good root process for this phone. Find anything yet?

I have a Canadian CLT-L04 that i rebranded and rooted to CLT-L29 with the guide on here.
https://forum.xda-developers.com/hu...de-how-to-root-debrand-remove-retail-t3788326
if you want better firmware compared to version 109 thats still on clt-l04 you can follow this guide, it worked well for me. (don't wait canadian OTA it'll take too long)
1) quite sure that TWRP is the easiest and safest way to root. Currently unaware of a better way to root the phone.
b) if you remove TWRP by flashing a stock recovery_ramdisk, root is kept. If you do an OTA though you might lose root.
2) thats here to stay i believe. Cannot find a way to hide it currently.
3)In this guide under the "install an OTA Stock Update: PC Method" you will find all the information you need.
cheers

I finally found the info I needed in this thread:
https://forum.xda-developers.com/hu...ide-getting-started-unlock-twrp-root-t3806180
Overall it was a very simple process and took less than an hour including reading. Once you've got your bootloader unlock code the all in one tool handles it from there. Unlock the bootloader, flash TWRP, reboot into TWRP, flash Magisk and you're done. You can flash the no_check file over TWRP if you want to be ready for updates but I decided to leave TWRP on for now. Loving having root on this phone so far!

On a different note, has anyone discovered any ROMs for this phone yet that can handle the notch? I almost tried Lineage until I found out there is no notch support. I've grown strangely fond of the thing for some reason lol

If you do a full backup of the L04 in TWRP before rebranding you should be able to go back to it easily at any time, just remember to save it somewhere safe other than the phone itself. If you've already flashed and are looking to go back you may find someone willing to share a stock backup if you ask around. But always best to do your own backup first, then you can go back whenever you like!

Anyone unlocked bootloader and rooted recently for the L04 model with 120(C792) Sept-2018 update?
Im scared to update before unlocking and rooting as the update might do something to fastboot etc. (this has happened to LG)
If not, then Ill update but if so, Ill just not update and unlock it as it is.

It's really easy to update once you've unlocked, I would suggest unlocking first if you have concerns. I have an L04 as well and just updated to 120 with no problems.

No problem, glad it worked for you. I've soft bricked and recovered my phone a few times now experimenting so if you run into any problems I'm happy to help! Lots to learn with the P20.

I have a CLT-L04 8.1.0.136 C69 with October security patch from Mexico I want to rebrand it to CLT- L29 to get wifi calling and get rid of all the bloatware. Could I use this tutorial from dladz's tutorial:

One of the notes mentions the following: I) ]NOTE*** If you are on a later firmware than 120, please do not attempt this guide!!
I have only rooted one phone before in my life so I am no expert. I do no want to mess up my phone becuse it is the only one that I have. Also If I unlock the boot loader and rebrand can i get OTAs and the upcoming Pie release? Thanks for the help!

LineageOS 15.1 on L04
I installed LineageOS 15.1 on my L04 with out any issue. Some things to consider. USB-C will only charge the device, Titanium Backup will install but doesn't get root access and you'll miss the camera application.

Did you install it with a locked bootloader ? I really dont feel like paying for an unlock code. Would like to try Lineage though.

I do have an unlocked bootloader. Truth is i'm addicted to Rom's lol. That in mind I have tried every Rom, kernel, flash-able zip within this Forum and I can't brick this thing. L04 Canadian. Lineage is the best Rom for our device.
Roms that work:
- Lineage - Hauwei camera can be installed and works, dark mode works well.
------- Doesn't work: USB-C audio, NFC, RAW Option in the camera, Second ear piece as speaker, main speaker works well.
- First Ever Android 9 - Being the first build it works well. (Note: When I installed this rom I never installed the RemoveEncryption-P20Pro.zip) Seemed to work just fine without it. I did run it just because I wanted to see if it would brick my phone. It didn't.
-------Doesn't work: Dark mode, NFC, RAW Option in camera, Second ear piece as speaker, main speaker works well, seems to kill TWRP. eRecovery needed to get TWRP to function.
- AOSP 9 - Berkeley-Flex - Do Not Use...not ready.

P9 no camera after update

Hi,
Wondering if anyone can help me with what looks like a self caused issue on my P9.
My phone was running EVA-L19C185B401 but I was having an issue where my when using the camera, occasionally the phone would die on low battery even though there was plenty of battery, the only way to recover from this was to plug the phone in and restart.
This problem became apparent on the last firmware upgrade, so as an experiment I attempted to roll it back.
The phone is now running EVA-L19C185B300 but most of the stock apps have vanished including the camera which is the reason I bought the thing!
The keyboard had also vanished but I got round this by plugging in a usb keyboard.
Does anyone know of a version of firmware that will restore my missing apps?
Huawei Tech Support are being as useful as a chocolate spoon.
Thanks in advance, Colin

Rebrand to C432 and start from scratch. search the topics on how to do it please. All the info you need is here. Dont focus on how to restore the camera but focus on how to rollback on MM version and upgrade it to the latest one.
About battery:
Because this phone is 2 years old, most likely your battery is dead and thats why it was shutting down when you could have even 90%. Or even when you turn on the camera is freezing and dies.
It happens to the best of us and 90% of the Huawei owners after excessive use ,charge,recharge because every battery has a specific range of recharging circles .
In this case you have to replace the battery.
If you dont have warranty on your phone due to unlocked bootloader, root, etc order a battery from eBay.
Ill go for something like this since it has pentalobe screwdriver https://www.ebay.com/itm/BATTERIA-O...381064&hash=item25e864e8dc:g:ZdcAAOSw3EVbI6CS
(Thats an example and you can search others but make sure you buy a pentalobe screwdriver and picks) the procedure was easy for me just follow that guide step by step.
If you have guaranty u better give it to your nearest Huawei store but expect to get it delayed.
Thats all i can suggest you.
Good luck on your research and restoring your device.

Hi, after may hours of feeling like a numpty, I can find no way of doing what you suggested.
I've gotten as far as unlocking my bootloader and installing TWRP.
I cant seem to find a version of SuperSU that works with my phone.
Could anyone point me in the right direction?
All I really want to achieve is to install a rom that has the Huawei Stock camera app?
No matter what I try, it seems I can't get away from EVA-L19C185B300.

wrong post sorry

vampirian said:
Suoer SU is dead for our devices with Oreo. Magisk will work for you. Now tge steps you have to do is to roll back in your first version. Use firnware finder to find tge rom you need. Pretty much honor 10 theoretically works the same with honor V10.. Reading their forums you might get a solution for honor 10. Do not install any if their firnwares. Just sre the programs they use and steps and replace their firmware with honor 10

Do you need to use a particular version of Magisk?
I tried with Magisk-v16.6 and all it seems to do is cause my phone to get stuck in a boot loop i.e. the Huawei splashscreen just starts to appear and the phone crashes, it'll keep doing this till I reinstall EVA-L19C185B300.

sorry my mistake i though your post was about honor 10.
The same though applies for your device , check here in general forum how to rollback your device on earlier version like marshmallow and then reupdate it to the latest Nougat one.
Switch to c432 is better for you

All the guides I see tell you to install EVA-L19C185B300, which is what I have, then flash EVAL19C185B210.
This stops after 5% and says there is a compatibility error, think I'll just need to accept that I've messed up my phone and just use it in its rather diminished capacity, tbh, it actually works better, it's only the camera app I miss, if I could root the damn thing I could install the camera APK.
Hey ho, thanks anyways.
Just need to start saving up for a P20 now haha

No no there is nothing you did that is terminal for your device. Rollback to marshmallow please and update, update , update r. Im coming back from my bands 6 day tour tomorrow. Ill be more than glad to help you fix the problem once i am back. I cant do it from the phone cause my fingers are like bricks after playing guitar so many hours.
PS: Think about the cheaper option i ended up as well. Honor 10
Im a big supporter for this device!!! Amazing on everything

ok with a quick search follow this guide please. Return to stock recovery before everything to rollback. After you roll back update to latest version and then we will find out which magisk Root will work . The important thing is to be safe without bricking your device and have your camera back.

Thanks matey, I had tried the roll back, it's this that seems to have mucked the phone up.
I completed the 1st step, going back to EVA-L19C185B300.
Bizarrely, I tried the rollback steps again tonight and it worked!
I'm now on Android 6 EMUI 4.1.2 and all the stock apps are back
I'm not quite sure what went on as I had tried the steps in the link before, it was the Update.app file in that link that rolled me back to B300.
I used the Firmware Finder App on Android Play store to find the B220 Firmware and hey presto!
I'm a happy, happy boy now.
Thanks for the info and help, hope your hands are returning back to normal after the tour

Does anyone know of a version of firmware that will restore my missing apps?
Huawei Tech Support are being as useful as a chocolate spoon.
Thanks in advance, Colin

The great adventure of rooting the XZ1C

Hello everyone,
I have to say I am completely lost regarding the whole rooting process for the XZ1C. I usually manage to get where I want just by carefully reading the forums, but with this device, I feel overwhelmed by information. And I sometimes feel like what I am reading contradicts what I though I understood from previous reads...
I will try to sum up what I know so far.
First of all, I have a just-out-of-the-box Sony model G8441 with firmware 47.1.A.12.179 / Oreo 8.0.0 (never been connected to the outside world yet), and I want to properly root the device and install TWRP with no loss of feature.
What I think I understand:
To root, I first need to unlock the bootloader, which seems to be a trivial operation. However, this will break some functionalities due to DRM keys being erased. Once it is done, there is no way, ever, to get them back. There are however ways to "trick" DRM-related functionalities into believing DRM keys are still there.
Alternatively, there seems to be a way to backup the DRM keys prior to unlocking the BL, and this backup can somehow be reused and injected back into the unlocked device. If true, then this would certainly be a preferable method than the previous one, which would then be obsolete. However, it obviously doesn't look obsolete when I read the related topics, so I must be missing something...
Another thing I noted (but do not quite understand): There are ROMs for this device that "include" a DRM fix.
Last important thing I read: there is a paid "do-it-all" tool which takes my locked device and, with one click, makes it unlocked - rooted - DRM-fixed - TWRP-enabled. Now that sounds really good! Maybe too good?
As far as i know (but I learn new stuff every day on this topic) this DRM stuff is the main difficulty here. I understand that the rest of the process (root + TWRP) will be much simpler (although I'm old-school and completly missed all this magisk trend...!)
What I don't understand:
I read that some people downgrade to Oreo to be able to root properly, and at the same time, I read that Pie removed the restrictions on unlocked bootloader. So I still have no idea if I should connect and receive Sony updates, or avoid them.
Another thing I don't get, is how many ways do we have to root this thing? In the past, I was used to see, for a specific device, always one major and widly used rooting method. Here I fail to identify it...
What I think I will do:
1. Backup TA partition with j4nn's tool. This will probably imply flashing an older firmware right? Is there any link that could help me with this flashing process? (I only know Odin - did I mention old-school?) I saw this page for generic sony Z devices, but the thread is from 2013 and now closed. Is it still up-to-date or is there a newer thread?
2. Unlock bootloader and restore TA partition.
3. Wait for Sony updates? Or should I first hide unlock status?
3bis. Alternaltively to waiting for updates, maybe I can just flash the latest build? (47.2.A.8.24 if I am not mistaken)
4. Flash modpunk's TWRP.
5. Flash janjan's Boot.img to get root functionalities?
Alternaltively to all the above (except maybe step 1 that I will probably do in any case), buy the paid all-in-one tool (Xperifix), plug, click and wait... But will I really end up the same as with the manual way?
I saw a few other methods in the forums but it seems my brain is currently refusing to bring them back...
That's all I have right now. I would really appreciate if you guys could share some insight and tell me what you think about this, whether there are missing steps, useless steps, incorrectly ordered steps, silly steps, or if I'm just completely wrong about the whole thing.
Feel free also to correct me on the assumptions I made at the beginning.
Thank you very much for reading this repulsive piece of text.

By the looks of it you have done a great deal of research on the project.
Yes, go down the route of backing up your TA partition first, but that is not a small step in itself, it's pretty complicated and if you get that working then the rest of the project will be a breeze.
You don't say what version of firmware you want to end up on. If you want to end up on Pie then forget the DRMfix . But if you're staying on Oreo and can't be bothered with lots of files & flashing, then this is the easy way out, I bought the paid version and can verify it works.
More recently I ended up janjan's kernel (Oreo build). Hidden root (Google Pay works), lots of performance tweaks, DRM completely working.
It's unlikely that anyone will bother making a DRM fix for Pie as the camera works and there are only a couple of other features that get disabled.
It sounds like you're not the sort of person who's only going to read the first couple of pages of a thread (or the last) flash the xxxxxx and then complain when it's broken.
The people on the forum here are very helpful and if you go into any of the threads you mentioned in your post with a question, you'll get a reply.
Good luck.

I agree, there is a lot of information out there and different methods of achieving what you want - very confusing if you have not been following the threads since the beginning.
In my opinion, the preferred method is j4nn's method outlined here: https://forum.xda-developers.com/xp...devonly-exploits-temp-root-to-backup-t3795510
Use that post as your main guide (the final step in that guide, #13, is how you will achieve root). You will use Newflasher to flash the various firmwares along the way (this is linked from j4nn's procedure in step #2). User munted made a very detailed pdf file that fills in some of the details on j4nn's procedure - see the following post and download the pdf attached: https://forum.xda-developers.com/showpost.php?p=78255334&postcount=382
Most of the other methods out there came before j4nn's work - they didn't include DRM backup/restore.
If you follow j4nn's procedure, you won't need to use the janjan kernel as you assumed - janjan method is different and does not overlap with j4nn.

Sorry, I didn't point out that I was one of the early 'jumpers' who unlocked their bootloader without any backups, so I have been forced into always using fixes and all the information I have is based on having to fix your phone for it to work, but that's all changed now. I'm so out of date :-/
 @camaro322hp is right, if you follow j4nn's method correctly you'll be rooted with no DRM loss. All of the other stuff is not required.

Thank you Digesteve and camaro322hp for your help.
From what I understand the XZ1C didn't get as much love as other devices, thus there was a long period of tinkering before a "do-it-all guide" could be considered "the" solution. That could explain all these different approaches that are proposed. Like you said camaro322hp it's rather difficult to jump on this train, and I can only guess how interesting this ride has been.
Anyway, I didn't see that the TA backup thread from j4nn also encompassed all the information I needed; I am glad to finally know that there is indeed a centralized "do-it-all guide" . To make it easier for XZ1C newcomers, I think j4nn should update his opening post to make this clearer.
Since I managed to grab the attention of 2 XZ1C power users, I would like to ask you: Did you keep stock? Did you try alternative ROMs? Do you like some of them? Do you prefer Oreo or Pie?
For information, the most up-to-date experience I have on a Android phone is my LG90 with CyanogenMod 11 (KitKat 4.4.4! Yes sir!). I heard that it's becoming less and less useful to flash a custom ROM due to major OS improvements, but I would still enjoy the simplest and lightest Android possible.

I've always been on stock, the camera is an important part of what I want from my phone and although there's lots of alternative camera apps, there's no competition to the stock camera app. Then I theme it black with swift installer and just uninstall or freeze any apps I don't want with Titanium Backup. I have stuck with Oreo, everything works perfect and I remember seeing so many people jumping to 9 then wanting to go back to 8 because they didn't like it. Something about changing the way the drop down menu works, among other things, but having never installed it, I'm not the person to comment on if it's any good or not.
I have been watching the XZ1c thread and Lineage is gaining ground, it even has a stock camera now. I would have thought something like that with miniGapps is going to be pretty lightweight and very similar to your carbon rom of before. At the moment this is based on 8, but is working well. Depends how keen you are to move to Pie.

Thank you Digesteve.
One thing I still don't understand. Part of the process is to hide unlock status. If I do this, FOTA will be applied and I will automatically end up on Pie, right? Should I skip this step if I want Oreo?
EDIT: when you say "a stock camera", you mean the Sony camera?

@SunJu22 I've stuck with the Sony ROM. A rooted stock ROM meets all my needs, so I've never felt the need to experiment with custom ROMs. There are some custom options out there that people seem fairly happy with, so if that's your thing, I'd encourage it.
Without going into too much detail, I'm still on Oreo for the moment, for a variety of reasons, but I don't know of anything that would keep me from recommending Pie.

One thing you should note is that once you unlock, there is no going back. AFAIK there is no known or working method to relock the bootloader.

Yes, I'm not entirely sure why having your rooted phone try and update itself is an advantage, but something I'd recomend avoiding.
Stock camera is the Sony camera, yes.

Thank you everyone, I believe I now have enough information to jump into this with confidence. The adventure begins, and will be reported in this thread for future reference, in the hope that it will help others like me!

Well, I am a bit sad... I wanted to report my "adventure" here in detail, but I'm afraid I have nothing to say.
Indeed, following the procedure from j4nn with a printed copy of munted's awesome guide, I managed to do all I wanted on the first attempt.
I don't have anything to add to this guide, everyone wanting to root their XZ1C can do it just by reading the opening post from j4nn and the mentioned guide. It takes a bit of time but nothing complicated thanks to the clear and detailed explanations.
I now have a fully functional rooted XZ1C (including camera) on Pie with Magisk root and TWRP.
Thank you all again from pointing me to the right direction.
I however have a slight disappointment. I wanted to start with Oreo and make an Nandroid backup before moving to Pie, but I didn't find Oreo builds on Xperifirm. So I jumped straight to Pie.
In case I want to test Oreo, I read that a downgrade is more complicated than an upgrade, but apart from the fact that a factory reset is needed for downgrade, I couldn't find an explanation for this. Any idea?
Last but not least: I looked for the latest Oreo build version number but couldn't find it. Do you guys know what it is and where I can download it?
I guess this will be all for this thread after this. Although it is very convenient to have my own thread to ask questions rather than finding the relevant page for each one, I don't want to annoy you too much...
EDIT: Please ignore the last question. I found out last Oreo build is 47.1.A.16.20, and I found the files via the download link in the opening post of the Lineage thread.

Hi, I've been thinking about rooting my XZ1c for a long time now. So, do I understand correctly that the ONLY disadvantage compared to non-rooted device is not possible to receive the OTA updates from Sony anymore?

No, you can flash a kernel to hide the bootloader unlock flag, this will mean that you will receive OTA updates, although depending on how you're rooted an update will most likely break your phone, so not that useful.

*made a thread*

Thanks--rooted withOUT adventure too
Very happily rooted now. Just wanted to say a quick thanks and add a few notes:
1. j4nn's renoroot to enable TA key backup and restore is fantastic. My advice: use and donate
2. munted's guide is excellent. clear and thorough...a rare combination.
3. do expect that renoroot may need to be restarted a couple of times. it took me 3 or 4 attempts to get temp root to pull the TA keys, although it took only 1 effort to get root back to restore.
4. topjohnwu's magisk is, of course, a key component to all this. Thx and $s there too.
I did a few things slightly differently/additionally than SunJu22.
5. I am on T-Mobile US, so I opted to create a hybrid Pie FW to get wifi calling and VoLTE. There are a number of discussions on this. I did it by combining the vendor**.sin and system**.sin files from custom-CH FW with the other files from custom-US FW. Of course (a) use IDENTICAL release numbers only, e.g. 47.A.2.10.28 w/ 47.A.2.10.28 and (b) you still need to delete .TA and persist files from the hybrid before you flash it.
Note: I don't really care about these features, but I have *heard* that T-mobile won't allow BYOD on their band-12 sites if they don't have VoLTE. Don't know if it is true (or where it is true) but figured why not?
6. I decided (for now, at least) to leave boot and recovery stock. So, I am using fastboot to run TWRP or a rooted kernel. Thanks again to j4nn for the method.
Note: I don't plan on allowing FOTA upgrades---I just like passing all the security checks and being able to *see* if updates are available.
That's all. Fine work in development and guides has made life simple and happy for me

Now riddle me this cause I'm on Tmo USA as well and I did the hybrid work fine as well but heres the question, does googlepay and banking apps still work with a unlocked bootloader or did you flash a modified kernel to hide the unlocked status.
Sitting on the fence about unlocking mine so I can do a full nandroid before trying out some gsi pie roms infact this is the first phone I haven't unlocked or least put twrp on since my samsung sidekick 4g o.o

kernel with hide-unlock

Full disclosure: I don't use Google pay or too many banking apps, so YMMV. But, I am using j4nn's kernel with unlock hidden. (See link in my note 6.) You can flash this, or you can leave in your stock kernel and merely fastboot to this. From what I have seen, it hides most - if not all -- indicators that the phone is rooted and the BL in unlocked.

Does somebody has :
G8441_1310-7123_47.1.A.16.20-R7B_Customized_CE1.ftf ?
Only backup i did not make, and its gone from XperiFirm.
Still have the feeling battery life was better in Oreo, and would be nice for experimenting.
Would be nice.
Thanks in advance.
