are you sure bootloader is unlocked? this happens only with locked BL
[HTC U12+ Guides, News, & Discussion] Marco589:
yes, I did; but to be sure is there anyway to check?
[HTC U12+ Guides, News, & Discussion] DeeZZ_NuuZZ:
yes boot into bootloader/download mode....
[HTC U12+ Guides, News, & Discussion] Marco589:
I took a pic so you can check it too.
[HTC U12+ Guides, News, & Discussion] DeeZZ_NuuZZ:
IT SAYS CLEARLY THAT THE PHONE IS LOCKED...wtf... you haven't unlocked it. just enabling tje option in the developer settings doesn't mean it's unlocked now..
[HTC U12+ Guides, News, & Discussion] 5m4r7ph0n36uru:
That's a problem I saw coming for a long time. You can boot TWRP with locked bootloader on U12+and flash away. And that's what you did.

Yes you activated developer options

There you swipe OEM unlock to on, as well as USB debugging

BUT you NEVER headed over to HTCDev to unlock you bootloader.

Download an appropriate RUU, flash it using SDcard method.

And stop tinkering, as otherwise you'll end up with a very expensive paper weight, as you seem not to familiar with what you are doing. Next time you leave a critical step out might be the last time you did it.

And how do you feel about the change to HTC? I'm really curious, how it works out for a long time OnePlus user.

Sorry for the off topic question
[HTC U12+ Guides, News, & Discussion] LibertyMonger:
I was getting the white box popup error message as well. This may not be proper but it has worked for me.

I have found that we have to make sure we uninstall the previous Magisk properly to avoid this error message. Since I have been running these commands from TWRP I do not get these error message anymore. First uninstall and then run these commands, then I reboot bootloader and TWRP before installing the new Magisk. I'm still not quite sure the exact proper way, but this has been working for me. We must have stock boot.img installed before flashing the updated Magisk. Supposedly flashing the uninstall zip does this, then run these commands...

echo KEEPVERITY=true>>/data/.magisk

echo KEEPFORCEENCRYPT=true>>/data/.magisk

Reboot bootloader

Reboot back into TWRP

Then flash updated Magisk

Good luck!
[HTC U12+ Guides, News, & Discussion] DeeZZ_NuuZZ:
You can also download the zip in the app and keep those boxes ticked before downloading. Either patch it then with the boxes ticked directly in the app or flash it from TWRP, worked fine for me too.

Maybe something has changed, I'm relocked again and will try 17.1 at the weekend
[HTC U12+ Guides, News, & Discussion] Marco589:
Honestly the OP5 was fastest, some times I notice lags.. never seen on the OP.

I left OP just for the SD Card (which is useful.. IMHO).

if I could go back... I wouldn't buy this again..

anyway it's just few days that I'm using it, maybe later on I'm going to change my mind :)
[HTC U12+ Guides, News, & Discussion] EMJI79:
Can we know use Magisk 17.1 which is stable?

OP says Magisk 16.0 which I didn't find in the linked thread or this thread.
[HTC U12+ Guides, News, & Discussion] Freak07:
Yes you can use 17.1 now! I’ll update the OP! Thanks for the heads up!

I just switched carriers and was receiving SMS but couldn't send them so I thought I would hide SMS and telephone activities from Magisk but at the moment I tick telephone, my smartphone got into bootloop.

I don't know what to do?
[HTC U12+ Guides, News, & Discussion] 5m4r7ph0n36uru:
First off you should know your ways back if you start tinkering. But I had the same, when hiding another process. I've been able to reboot to bootloader and afterward to download mode to flash a RUU, by the method I described on my guides thread, if fully booted. Ling press Power wait for the long vibration, switch to pressing and holding volume up instantly. My need some try in such a situation, but I've eventually been able to do so as well.
[HTC U12+ Guides, News, & Discussion] EMJI79:
In fact I just uninstalled Magisk and reinstalled it and I was solved.

---------- Post added at 11:46 PM ---------- Previous post was at 11:43 PM ----------

In fact there was a step when I got bootloop also when I ticked "fingerprint" which I find strange but uninstalling and reinstalling Magisk also resolved the problem.

Cannot get into bootloader

Hi,

I cannot get this to boot into and stay in bootloader mode. I do the power, volume down process. The bootload boot screen is displayed but then if I let go the phone will boot into normal mode. Argh!
[HTC U12+ Guides, News, & Discussion] DeeZZ_NuuZZ:
Enable adb in developer settings and use adb reboot bootloader. Maybe that will work better for you
[HTC U12+ Guides, News, & Discussion] blocka:
Yep that's exaclty what I did, and have now unlocked the bootloader. Cheers for the reply anyway.

Maybe the original poster who put together the guide may like to think about adding those instructions to his overall guide?

Cheers!
[HTC U12+ Guides, News, & Discussion] DeeZZ_NuuZZ:
The button method should work fine too, sometimes they act strange though and you can't properly boot into one of the modes. Worked most of the time fine for me, it's like you have to learn it like riding a bike ?
[HTC U12+ Guides, News, & Discussion] 5m4r7ph0n36uru:
As everybody tinkering with his/her devices, the adb/fastboot commands should be known to them already and be made flesh and blood. Thus I'd just do it like the OP and only add to it methods which are special/new for the respective device.

Reading through the steps, and preparing to root my device I've gone to the google docs spreadsheet looking for my models bootimage.

Boot TWRP... Backup boot and you have the stock boot. Easy peasy done
[HTC U12+ Guides, News, & Discussion] blocka:
You can do what I've just done and use TWRP to backup boot.img.

---------- Post added at 17:00 ---------- Previous post was at 16:46 ----------

I backed up the boot.img using TWRP (it's been a while since I've done this stuff, my last phone is a HTC M9 so about 5 years)

Ideally I'd like an image i could flash as a backout but there doesn't seem to be anything available from the links tha I've seen. My system is . . . so any help with getting my hands on the ROM would be great.

(bootloader) product: htc_imedugl

(bootloader) version-main: 1.25.400.3

(bootloader) version-baseband: sdm845-000201b-1807311356

(bootloader) version-bootloader: 1.0.0.0000

(bootloader) mid: 2Q5510000

(bootloader) cid: HTC__039
[HTC U12+ Guides, News, & Discussion] DeeZZ_NuuZZ:
Just rename it to boot.img and you can flash it via fastboot too
[HTC U12+ Guides, News, & Discussion] blocka:

Hey there [MENTION=3428502]Freak07[/MENTION], I'm looking for a bit of guidance on this whole A/B thing.

I've read through the OP and searched this and other threads for the answer to my question, but I haven't been lucky enough to find it.

Does OTA check both A and B partitions?

If I had a full stock on A and magisk on B, would OTA work?
[HTC U12+ Guides, News, & Discussion] DeeZZ_NuuZZ:
Hey mate, it checks the current active slot, so if vendor and/or system are tampered, you can't install the ota. But the ota also checks the inactive partition, so if you flashed stuff on it from a newer base already, it won't work too. At least wasn't working for me, had to use an older ruu to be able to get the ota, because I accidentally flashed vendor or system on inactive slot from higher base.

Also for the last question smartphone-guru made a thread for heaving stock on one and magisk patched on other partition and it should work afaik. But you can read in his thread more about it, it's also in general forum

[HTC U12+ Guides, News, & Discussion] Kyuubi10:
Thanks man! Pleasure seeing you around here :P

Thought you moved to OnePlus permanently!

So OTA checks /system and /vendor.... Does it check /boot also or not at all?

What I'm trying to get to is, does OTA use recovery at all? If I have TWRP and custom Kernel without Magisk (therefore /Vendor is stock)... How would that work?
[HTC U12+ Guides, News, & Discussion] DeeZZ_NuuZZ:
Lol nope, zero and the others have OnePlus devices ? p50kombi still uses his u11. I will never move to OnePlus haha

Yeah afaik boot is also checked and it needs the proper stock recovery.

So you need to restore stock boot. The recovery is integrated into the boot, so there is no real recovery partition
[HTC U12+ Guides, News, & Discussion] Kyuubi10:
Haha Shame! We lost some good developers!

Though really happy zero is still carrying on with his project, I always knew the work he was doing had plenty of potential.

We still have you though, so all is good, no need to panic :P

Thank you for the information!! it is very useful and it will also help me troubleshoot what is causing the bootloop when I try to install Dolby Atmos.

I'll try to get it to work.

I'll be happy to join back, I just need to find some stability first haha.

Looking forward to all the learning ahead, it will be very interesting what the development community comes up with, I'll need to update my guides, maybe come up with some new guides.

Okay guys. Please bear with me....

I rooted my phone on day one when I receive it. (long time ago) Yes I did it the way as described in the 1st post from Freak07.

All great and I was happy as I could install some apps that needed root.

Some days later I dropped the phone and yes.... The screen cracked. That was a bad/sad day for me and from that day onwards I treated the phone as it was an old phone (read ex girlfriend / wife)

No more tweaking. No more hugging and so on....

Anyway. It's time to give the phone some TLC again. Okay. It's still got a cracked screen, but besides this it's working fine for me.

Gizmo (that's the name of my phone) is still running an old version (1.15.401.4).

Is there an easy way to update the phone? If so.. Anyone here who can point me in the right direction.

Gizmo and I would really appreciated it!

Thank you.
[HTC U12+ Guides, News, & Discussion] DeeZZ_NuuZZ:
Just get the newest ruu available for your MID/CID. Easy as that. Be sure to backup everything from your phone and transfer it to the PC or so. Ruu will wipe everything. But then you can root again. But there are some guides on how to get back to untouched system and be able to install OTA.

Yes, you boot the latest TWRP and go to advanced, click on sideload and swipe to start the side load. Then enter the command.. adb sideload Magisk-v19.3.zip

You must have the latest Magisk in your adb folder or platform-tools folder

But I'm on U.S. Pie so hopefully it works for you the same. All zips will need side loaded since you can't see internal or external storage.

How are you able to flash magisk in your device.?I had a Taiwan version and it's on 2.47.709.1, security level 7/1/2019 and never rooted before. When I tried to sideload magisk using TWRP, it failed but it didn't bricked my device. I think the problem is when I get into TWRP it told me to enter a password that doesn't exist because TWRP can't read my internal storage without a password.I formatted the data file to crack the FBE and it just doesn't work.I can't even downgrade my device to Oreo by deleting the ROM version number(from JEANRIVERA) because it doesn't work,either.By the way, I don't have the newest Taiwan version RUU file because I can't find it on the internet, if you have it, could you please contact me at jamesho451@gmail.com because I'm afraid that if my device is bricked I won't be able to fix it.:o

Hey guys,

i've a brandnew mobile and having some troubles to get root work:

after first installing and updating to android pie, i tested the twrp boot and flash magisk variant to root it, stuck in a bootloop. had now two days many trouble, to flash back a system and boot image, now slot a is working, but only on oreo. update to pie is broken:

l get every time a message, that my filesystem is tampered...

So my question is: how do i get the phone rooted, get the newest android pie AND get root working?

Thanks in advance for some tips,

ToM
[HTC U12+ Guides, News, & Discussion] qriozum:
Downgrade to Oreo via RUU and then flash "system" and "boot" to slot "B". Next is OTA for the temporary build and the second step is OTA to Pie. The last step will be root on Pie.

regards

q.
[HTC U12+ Guides, News, & Discussion] Nightwing0815:
Thanks, that was part of my trying... RUU failed with something like fail android info 09 or so.

I've managed a flash from system and boot to A, its working, but B isn't working, flashed there the same thing on sunday...

Any idea(s), how to repare that, to get both working like they should, to get ota?

RUU for pie isn't available yet, isn't it?

Thanks in advance,

ToM

PS: Is there another rooting method than magisk? i personally don't like this, had trouble back in htc10 with it, sometimes it looses root after reboot, very annoying...
[HTC U12+ Guides, News, & Discussion] qriozum:
Downgrade:

Flash "system" & "boot":

Now you are doing OTA updates to "PIE".
