[Samsung Galaxy A12] uluruman:
I can't try anything any further because I've given the phone to the relative of mine as a present. I'm planning to buy the same model myself, as soon as I'll do it I'll continue my attempts, because personally I just don't want to use anything besides Lineage OS.
[Samsung Galaxy A12] LAST_krypton:
If you want just linageos then I recomend you buy something that has the orginal LinageOs official support. Or you can buy a Pixel phone that has graphenos support then install graphenos and re lock the bootloader and you will be golden.

graphenos supports full verified boot.
[Samsung Galaxy A12] uluruman:
These are either too expensive or not available in/deliverable to Russia.
[Samsung Galaxy A12] uluruman:
OK, now I have my own A127F to experiment on. This time I did not upgrade the firmware to rev3 and double-checked that the firmware I downloaded is the same SER_A127FXXU2AUH4 (rev2) firmware which was installed on the phone from the factory. I followed the phyzwizz's instructions and finally got the Magisk-patched file not rejected by the phone, so I got it rooted fine, but unfortunately installing TWRP was still unsuccessful: the afaneh92 version causes the infinite reboot cycle, the edward0181 version causes freezing and eventual reboot (just like it was before). No way to get to TWRP no matter when and how I'm pushing the vol+ and power buttons. Reflashing the Magisk-patched AP file gets back the working system. Dunno where to move further.
[Samsung Galaxy A12] uluruman:
What's interesting is that with the afaneh92 TWRP each time it reboots it looks like it's actually going to exec TWRP because of the short time spent on the logo screen, but goes into another reboot instead. I guess there is barely something needed to be fixed.
[Samsung Galaxy A12] honzazkrumlova:
Almost the same for me. Afaneh92 twrp boots for me, but unable to mout Data partition correctly, Edwards one freeze the same way you described.

Just a workaround with Afanehs one - I hold VolUp+Power not infinetely. When phone starts, opened bootloader warning comes, later screen with some other Samsung warning appear and 1-2s after that I released Power - if I dont, restart again, no clue why.
[Samsung Galaxy A12] uluruman:
Just tried it - doesn't work for me. Nope at all. Just the endless reboots.
[Samsung Galaxy A12] uluruman:
By the way, only the A21S patched Magisk works with my A127F/DSN, I double-checked it. boot.img patched by the original v23 Magisk causes a freeze and reboot. The patched Odin is not needed, the original one works fine.
[Samsung Galaxy A12] honzazkrumlova:
As I read somewhere, Magisk 23 has some problems and better you should download patched Magisk 22. Also there were mentioned, its better the patch whole AP file, not just boot img and this scenario works for me (rooting), also TWRP (afaneh) can be done - can backup some partition, not all of them.

[SOLVED] Samsung A12 / SM-A127F/DSN - Root problem

Hello, I have problem with patch my boot.img with Magisk manager. After patching I got error : "The phone is not running Samsung's official software". After flash again stock boot.img everything works. I use Odin to flash. I tried to install...

xdaforums.com

Post #6

.... in short: patched Odin, Patched Magisk and patched whole AP, not just boot.img

Then, TWRP from https://xdaforums.com/t/root-twrp-kernel-gsi-for-sm-a127f-a12s.4352297/

post #2

Also, what I have read no clue where, MTP can damage big files and for those PROs here, writing their TODOs its invisible routine, you should just to be sure patch AP thru Magisk in phone and then move patched file to PC better by adb pull command.

OK?
[Samsung Galaxy A12] uluruman:
Yes, I've rooted the whole AP with the patched Magisk 22. I suppose one must patch the whole AP because vbmeta.img also must be changed to reflect the changes in boot.img. At least these two files are the only files changed by Magisk in my case. I've packed them both into .tar and successfully reflashed many times when needed to quickly bring the phone back to life after the failed experiments with the other versions of Magisk. As of TWRP it just does not work for me, I don't think I'm missing something here, I probably just have some less common version of the phone (it's SM-A127F/DSN made in Vietnam for the Russian market).

Edit: oops, I was wrong, I'm actually using the patched Magisk 22, not 23.
[Samsung Galaxy A12] honzazkrumlova:
I have the same model A127F/DSN, originally VDF Czech Vodafone with change to XEZ (Czech generic).

Just two ideas:

I do believe, Magisk23 cannot work because of different CPU, really try patched one (magisk 22 patched) in thread I linked for you.

As a second, I move to phone whole stock original AP file, Magisk can patch whole AP, so there is no need to repack it (boot, vb, whatever) back as you mentioned, simply adb pull pacthed AP and flashed it. No clue, if this can affect, but well, If I know procedure what works, why experiment.

Really, as you wrote "don't think I'm missing something here", I quess its the Magisk version...

TWRP partially worked then.

In the end, I am at least able to backup boot,super,dtbo
[Samsung Galaxy A12] uluruman:
Oh, sorry, I was wrong, I've actually used the patched Magisk 22 all the time, not 23. I'm not used to Magisk and didn't know where to look for the currently installed version number. Magisk 23 did not work for me at all, caused the freeze and reboot right from the beginning.
[Samsung Galaxy A12] uluruman:
Actually, I'm a bit tired of all this. As an old Linux user, long used to the neat and well working systems, I just wonder how much frustration such a small thing as a smartphone can cause. I hoped that after all these 10 years, since I last tried to own an Android smartphone, they have become cleaner and more customizable. But of course not. I feel I'd better try to get a Fairphone somehow in the future, it's still a much much cleaner solution than this type of hacking.
[Samsung Galaxy A12] honzazkrumlova:
Well, I am little bit disappointed too, but A127F is not mainstream hardware, thats the fact and less consumers, less developers, more bugs :-(
[Samsung Galaxy A12] honzazkrumlova:
Oh man, just a stupid question, pardon me If I underestimate you. but this mention brings me for an idea. Did you, after Magisk-patched AP flashing, did zou "finish the process" by running Magisk and let him finish the job? There is a version number by the way
[Samsung Galaxy A12] uluruman:
Yes, I did. I tried many combinations, but actually all these hit-or-miss methods are against my principles. I feel like I'm wasting my time. In the past I had succesfully installed LineageOS to an Asus pad and a phone but that was the official release for these devices, and it didn't require any rooting at all. I just hope someone can really clarify what am I doing wrong and why it is so hard. For example, I don't understand why rooting is needed to install TWRP at all because as far as I know Recovery is executed by the first-stage bootloader, which is executed before loading the Boot partition. Magisk patches mostly boot.img and has nothing to do with recovery or the first-stage boot at all.
[Samsung Galaxy A12] honzazkrumlova:
With this logic, yes, it should be enough just to open bootloader.

My hope stays with short mention from afaneh92, autor of TWRP, claiming 3.5.2-afaneh92-R is not final release
[Samsung Galaxy A12] MoHaG:
I'm having similar issues to uluruman with this one. The ones from these two threads boot, but the screen is black. (I left some logs on the first thread)

I'm on a A127F/DS (unsure if the "DS" part matters) with the A127FXXU3AUJ5 bootloader. (One of the threads have a separate version version for the "U3" one, not sure if it is relevant)

It gets stuck on the screen with the bootloader warning at the top, "Samsung Galaxy A12" in the middle and "Powered by Android" at the bottom. (When holding Vol+ and Power) (the other recoveries goes to a black screen without backlight around here)

Magisk seemed to install fine with the rooting guide....
[Samsung Galaxy A12] panda822:
does this TWRP work on M127F with encryption? I don't want to disable encryption.
[Samsung Galaxy A12] sam-sepi0l:
I think someone encountered this issue in the beginning of the thread, but I dont understand what I'm supposed to do with the downloaded recovery.tar.zip file. If I unzip it into it's .tar.7z form it doesnt get picked up by ODIN. And if I unzip it further into the .tar.md5 form, it gets picked up by ODIN, but stuck at the SetupConnection part. What file should I flash into ODIN?
[Samsung Galaxy A12] uluruman:
.tar.md5 is the correct form, you should flash it into the AP slot of Odin, if you're getting further problems then check the connection, may be a USB driver for your phone is needed.

P.S. I don't know why this file was onion-compressed at all, like it was needed years ago by some hosting services for the non-standard file formats.
[Samsung Galaxy A12] sam-sepi0l:
Thanks, it worked. But I ran into the same issue you did.

So there's really no present way to install a custom ROM into the A127F then?? That's really disappointing. I was hoping to use Lineage for it's privacy..
[Samsung Galaxy A12] uluruman:
I have successfully installed LineageOS and tried several other OS'es by repacking super.img. I think this is the only way because there is no real system partition on A127F, only a dynamic partition inside the Super partition. As I am on Linux I've made a script automating this rather complex process, and people also reported successfully using my script under Windows using WSL. Recently physwizz made a version of Orange Fox and even custom kernels all working with A127F baseband versions U3 and U4, but changing OS is unfortunately only by replacing the whole super.img (read the next post by physwizz for a possible alternative method), which you can flash either by Odin or by the aforementioned Orange Fox, although for beginners I recommend plain Odin.
[Samsung Galaxy A12] physwizz:
This twrp allows you to flash to system

https://xdaforums.com/t/afaneh-twrp-for-a12s-exynos-850.4371383/
[Samsung Galaxy A12] uluruman:
Just tried it, it does not work for me. I'm getting a message "Size of image is larger than target device", even when trying to flash the stock system.img. It is obvious that even TWRP doesn't know how to flash dynamic partitions correctly.

EDIT: I remember there was something called DynaPatch which presumably allows flashing dynamic partitions. I shall try it.
[Samsung Galaxy A12] physwizz:
You can resize the system partition from twrp

1. Wipe, advanced wipe

2. Select system, repair or change

3. Resize file system
[Samsung Galaxy A12] physwizz:
Installing a GSI

for a12s(a127f) and m12(m127f)

1. Unzip img file

2.Wipe data from twrp

3. Install IMG into system

4. Install my kernel

5. Reboot

If you need to install GApps

1. Wipe, advanced wipe

2. Select system, repair or change

3. Resize file system

4. Install GApps
[Samsung Galaxy A12] uluruman:
After some experimentation with TWRP for the U3/U4 baseband I can say that it works

almost

completely. It still cannot do one critical thing: wiping the data partition, trying to do this causes the "Failed to mount '/data'" error, and nothing is actually wiped. The data partition also cannot be mounted. Without wiping data LineageOS is stuck forever on the welcome animation screen.
[Samsung Galaxy A12] physwizz:
Did you format data?
[Samsung Galaxy A12] uluruman:
I cannot do that either. The same error. May be that's because I'm trying to use the U4 version while my phone is U3, but there is no TWRP for U3, the one in that post is actually Orange Fox, not TWRP. For now I've used TWRP for flashing the system image and that Orange Fox for formatting data, although the latter gives tons of "E:A render request has failed" errors at every operation possible, but seemingly works fine (in contrast the U4 version of Orange Fox from this thread has no problems whatsoever besides not being able to handle the system partition, which is a share because that would finally make it a completely functional recovery tool for SM-A127F/DSN U3/4).
[Samsung Galaxy A12] physwizz:
I'll try to add the system partition to fox.

Which TWRP are you using?
[Samsung Galaxy A12] uluruman:
TWRP for U4 v2 from this post.
[Samsung Galaxy A12] physwizz:
U3 and u4 are interchangeable.

Both incompatible with u2
[Samsung Galaxy A12] uluruman:
My firmware is U3. So TWRP for U4 does work almost completely, but alas has some trouble with the data partition. No way to format it, erase or mount.

Very strange

[Xiaomi Mi 11] Jaegerist71:
Hello guys !

My Mi 11 5G that i bought 4 month ago is facing heating issues since Miui 12.5

I don't play games, just social médias and Netflix/YouTube

On Miui 12.0.2 i never faced any issues...

Heating is localised on the bottom of the screen just on the navigation bar !

Sometimes it spread to the entire phone

Since Miui 12.5.7, Battery has been improved but heating is still présent...

After several Factory reset and download the latest package, I'm concidering to sell it ....

Do any one has a solution ?

Can a Hard reset be useful ?

Thank you !
[Xiaomi Mi 11] Wahoux:
Really weird, i don't see what could heat at the bottom of the smartphone since the motherboard is at the top of the phone.

[Samsung Galaxy A52s 5G] nadastry:
If I put a custom ROM onto the A52s will I have a worse (or better?) camera or camera software compared to stock Samsung firmware?
[Samsung Galaxy A52s 5G] freecap:
In my opinion, the best 3rd party camera app is Open Camera. So if you want to check how the camera would perform on a custom ROM, install that app on the stock ROM and make sure you select Camera API 2 in the settings.

That being said, there is no custom ROM for any of the A52 devices yet.
[Samsung Galaxy A52s 5G] Pokemetti2:
Also there are a lot of reports that your camera won't work at all (firmware issue) if you unlock the bootloader, which you would definitely have to do to install a Custom ROM.
