This one flashes and boots the first time, but after a reboot there is the infamous error "only official released binaries are allowed to be flashed"

No problems on my end, pal.
[Samsung Galaxy A20 Guides, News, & Discussion] /dev/null/:
this phone is really a PITA. every time i try to do something it's 1 step forward and 2 steps back. never suffered so much. i flashed it like 20 times. all i want is a working twrp on stock rom and pass safetynet
[Samsung Galaxy A20 Guides, News, & Discussion] stiusamerg:
to bypass this error:

1. connect to wifi

2. change the date to 2 august 2019

3. boot into download mode

4. flash twrp

Thank you! It worked! No problems got me.

I kinda feel like idiot that I couldn't install it with that ease before

Hello,

I have a Samsung A20e running with the a202fxxu4cvk1 firmware (a11 version). I would like to install twrp and then to root it. I tried several tutorials (Odin, OEM unblocked, USB debugging, time change) but twrp installation fails with message 'custom recovery blocked by frp'.

Can anyone help me?
[Samsung Galaxy A20 Guides, News, & Discussion] lPolarisl:
I duckduckgoed, and found this XDA thread, where the second post says the following :

The rest of the posts mention the need for a modified boot.img, else your phone would brick after adding a Google account, but I don't know about that... I have MicroG on mine with a Google account and no problems.

Anyway, frp seems to be a related to having a Google account on your phone.
[Samsung Galaxy A20 Guides, News, & Discussion] fjunk:
Hello..I was wrong. My issue is not related to frp but OEM. OEM is unlocked according to developper menu but is not effective. Not able to upload any custom rom or bootloader.

I read that there was issue (use of a volume up button in download mode).

Any idea?
[Samsung Galaxy A20 Guides, News, & Discussion] fjunk:
Indeed, my issue is that in download mode I can only do a volume down button and power button to reboot in system mode. No option to unlock bootloader.
[Samsung Galaxy A20 Guides, News, & Discussion] lPolarisl:
I think you only need to do that once, afterwards, download mode doesn't warn you.

What error message do you get exactly when trying to flash TWRP, at what point, and what gives it (phone, odin) ?
[Samsung Galaxy A20 Guides, News, & Discussion] fjunk:
Many thanks for your update. Attached are pictures of the mobile and the Odin result. The error is an OEM issue (red text on the top of the mobile screen). In other forums, I can see that the download mode has an option to unlock OEM bootloader. I can't see it on my phone.
[Samsung Galaxy A20 Guides, News, & Discussion] lPolarisl:
Putting the camera so that it covers the error message, what an amazing idea xD

I have never encountered this error, so let's start from the beginning.

Have you enabled the developer options, and activated "allow USB debugging" on the phone ? Also, if there is an option "allow OEM unlock", activate that as well (not all Samsung phones have it).

Have you installed the proper ADB and Samsung drivers ? Which version of Odin are you using ?
[Samsung Galaxy A20 Guides, News, & Discussion] fjunk:
Thanks for your reply.

That's sure that it doesn't really help to hide the error message. Usb debugging is enabled (I am able to run adb commands) and OEM is unlocked on the preference setting. I did the test with Odin 3.13 but same results with newer version. I installed an A11 firmware (a202fxxu4cvk1).

Don't t know how to go ahead. It seems that I don't have the possibility to unlock OEM in the download mode interface....
[Samsung Galaxy A20 Guides, News, & Discussion] lPolarisl:
Wait, what is that about the firmware ? What did you flash, how and why ?

also, try a patched version of Odin from this post (I have 3.13.1_3B)
[Samsung Galaxy A20 Guides, News, & Discussion] fjunk:
I bought a refurbished mobile phone (blackmarket). It came with a 9.0 version. I tried to update to a custom rom without success so I installed the latest 'official' version

[Samsung Galaxy A20 Guides, News, & Discussion] lPolarisl:
Huh...

I have no idea how that behaves, but I hardly see why it would cause a problem.

What else could you try... Restore factory settings maybe ?

Pressing volume up when starting in download mode ? (Note, this supposedly relocks the bootloader if it has been unlocked, if that happens and your phone isn't 100% on stock, it will brick.)

Hello, I already did a restore factory settings... I don't see what can I do more. I am pretty sure that there is an issue for unblocking OEM mode. When I am in download mode, I don't see any information related to the firmware/ others options.
[Samsung Galaxy A20 Guides, News, & Discussion] lPolarisl:
Yeah, it's very strange... Try doing the procedure to relock the bootloader ? Maybe it will sync download mode or something...
[Samsung Galaxy A20 Guides, News, & Discussion] fjunk:
Hello, just for information. I was able to unlock OEM following these steps:

_ power off

_ press up/down keys together with the power button

_ then plug a USB cable (connected to a computer)

_ mobile starts up with a menu that proposes to unlock the bootloader (volume up)

After unlocking, I was able to install TWRP, magisk, and a lineage rom

Eureka Releases - Browse /Samsung/A20e/T/lineage at SourceForge.net

This organisation builds roms and recoveries for various A devices

My mistake was about plugging the USB cable and the laptops. I did a first attempt an then a second one using another (newer) laptop and it worked.
[Samsung Galaxy A20 Guides, News, & Discussion] lPolarisl:
Huh, didn't think that would be important... I gues I never started my phone in download mode without it being plugged to a computer.

Anyway, nice job figuring it out, and thanks for posting the solution ^_^

[UPDATE]

-Updated version of Magisk

# Magisk v24.3 --> Magisk v26.1

For ANY help contact me on Telegram: https://t.me/SerbianGeek
[Samsung Galaxy A20 Guides, News, & Discussion] buebue#8888:
Cool and congrats that you got it done!

Im stuck somehow, got the same new A11 firmware.

I was able to root it without TWRP, extracted the same firmware's AP and extracted the boot.img, patched it with Magisk 26.1 and zarchiver repacked it to .tar and flased that.

What Im now facing is that I got rubberbanding. I done that for spoofing with Pokemon Go. I did that:

I flashed those modules in Magisk:

- Smali Patcher 0.0.7.4

- Couldnt login into PoGo accounts, so I installed Universal SafetyNet Fix v2.4.0, worked.

Didnt got the teleport to original location fixed

- Than I deactivated Smali, reboot, and installed Zygisk Lsposed Module v1.8.6 (6712) along with hide mock location 2.0.9

- first I enabled system framework in hidemocklocation, still rubberbands. Than I enabled system frameworks AND PoGo, still the same. Than I enabled only PoGo, what the most people have set like, and its still not working. Also deactivated all

- the google location settings

- in gps joystick settings I set indirect mocking stuff etc off

- tried fix 4, and also the enable a-gps stuff.

Anyone has a fast fix for that?

If not.. I could also try to install Custom Rom, got to that link that was posted above but there are 3 topfolders, called "T" "S" "R", what they are for, and which one I have to choose?

Is it somehow possible to downgrade this to A10 and try Smali again? It didnt let me downgrade so far as the bootloader has like something like a protection I read and I got vbmeta.img errors as I tried to with Odin.
[Samsung Galaxy A20 Guides, News, & Discussion] buebue#8888:
Here are my screenshots of this mess.
[Samsung Galaxy A20 Guides, News, & Discussion] lPolarisl:
What is rubberbanding ?

From the sound of it, R, S and T probably refer to the android versions (11 - Red velvet Cake, 12 - Snow cone, 13 - Tiramisu).
[Samsung Galaxy A20 Guides, News, & Discussion] KeithSJS:
But how? I have tried quickly pressing the right buttons to get to Recovery after flashing TWRP but that doesn't work and fastboot (I understand) doesn't work with Samsung devices.

There are a lot of moments throughout a lot of applications when adaptive refresh rate just decides that it's the moment to use 60hz. The one that annoys me the most is the unlock animation.
[Huawei P10 Questions & Answers] rxsewxter:
Hi everyone, sorry if this has been asked before, I'm just curious to find out, I have a Huawei P10 on the way (UK) and was wondering if I could manually update it through the SD card method without Bootloader unlock. I'm not sure if the bootloader is unlocked yet, it should be here tomorrow. I have what I believe is the Harmony OS ROM file (update build VTRLGRP1CHN 10.2.0.0.106) and would like to install it to the P10. I'm not worried about losing GMS, in fact, that's my primary reason for wanting to get the Chinese ROM on it. any advice or help would be greatly appreciated :)

can it go on branded??

I've been trying to find out the answer to this for a few days....but I get a bit confused with all the answers, terminology and talk of hard spl etc..

so please forgive the question... I would like a simple yes or no answer just to confirm what I think i understand from other threads...

Can the normal HTC supplied update for WM6.1 be applied to a branded phone (in my case Orange UK) without having to make any other adjustments first???

Thanks in advance
[Touch Dual, MDA Touch Plus ROM Development] deffez:
thx but i need the italian version..
[Touch Dual, MDA Touch Plus ROM Development] bdacier:
Nope, you need to flash the uspl first. Check the sspl/uspl/hardspl thread. It's quite easy, first you put sspl on the phone and run it, then when the phone is in bootloader you flash the uspl. After flashing you can check if it went ok by going into bootloader (check wiki how to do it). If you can confirm that you have uspl, then just flash the new 6.1 original.

There's nothing else to it (it works also on vista). I did it with my t-mobile branded phone.
[Touch Dual, MDA Touch Plus ROM Development] vcdwelt:
Sorry so far i know is there no Italien Version at the moment :(
[Touch Dual, MDA Touch Plus ROM Development] lordrorthorn:
Thanks for that...I believed that was the case but there is sooo much info on here it was difficult to get to the bottom of it.

I'm not sure I want to do all that...if i brick it I can't afford a new phone so I might just leave it be.

Also, has anyone actually done this with an Touch Dual on Orange UK? does it work? The only confirmed upgrades i've found are on T-Mobile.

It would be a lot easier if Orange just supplied it wouldn't it????
[Touch Dual, MDA Touch Plus ROM Development] ed33:
Yeah ive done mine, i was orange uk. Works fine. Just follow the instructions.
[Touch Dual, MDA Touch Plus ROM Development] tuneboy2005:
Ok i have a UK version Toch Dual wich i bought here in belgium so it was already unlocked since i could use it on belgium networks. Also it is an unbranded one.

I flashed yesterday the new Official HTC Rom Windows Mobile 6.1 wich went all well no problems with flashing. It is a good rom, faster than the previous one. My question is since it is already unlocked can i flash any custom rom i can find here in the touch dual forum ???

Or do i have to do something witch the Uspl or hardspl ??? what is the different and what are the steps to use it with custom roms???

thanks alot

[Samsung Galaxy Z Fold3] 白い熊:
I'd like to use the Fold 3 as a night clock, positioned next to the bed, with the phone unfolded to the right angle and the AOD displaying on the outer small display - now being vertical and thus easily seen from bed only upon opening your eyes.

The problem is - before you reach this 90-degree position the outer display is shut off and the internal display comes on.

Anyone have an idea how this might be achievable?
[Samsung Galaxy Z Fold3] jeromepearce:
80 or even 85° at a push seems to leave the outside screen on. Is 80° not enough?
[Samsung Galaxy Z Fold3] 白い熊:
Let me try - it seemed to me it flipped sooner :@)

You are right - at least on A12 now it's OK. I seem to remember it flipped sooner on A11, but maybe imagining things now... :@)
[Samsung Galaxy Z Fold3] 白い熊:
OK - so this is what confused me: I was opening the phone with the AOD on already - there it flips to the internal display immediately once you open it slightly.

If you keep the screen on, you can open to like 80 degrees and then turn the screen off - the AOD comes up still on the external display.
[Samsung Galaxy Z Fold3] ronaldheld:
Maybe a short video might help?
[Samsung Galaxy Z Fold3] annson08:
1. While the phone is folded, open camera app.

2. Choose "selfie on the right top corner

3. Unfold the phone to 90°

4. Turn off phone's screen

5. ???

6. Profit

I found an easier way: :@)

- Close the phone.

- Turn it on.

- Turn it off - AOD will come on.

Changing second is possible.

Yea I wondered this as well. My older Motorola phones (Razr HD MAXX and Turbo) you could reflash a modified boot logo after your were rooted and make it go away. There was still a N/A on the screen but better than seeing what you normally do. I don't think it would be as bad if it did add like an extra 5 seconds to boot.

[LG V40 Questions & Answers] ZefonDecker376:
I have followed member:okey.benjamin, first posted on 5/8/2021, regarding USB CONFIGURATION SETTING on LG phone.

This member also included an MP4 that is virtually identical to the response I personally get with MY LG K31(non-rooted) phone, when I try to change the USB configuration setting from "charge-only", to ANY other configuration.

I too need to connect to PC from phone, so this COMMON LG problem should start to receive Greater attention And merrit.

My personal contribution to this problem comes by way of thrown errors that appear on my screen when installing certain Android Settings apps.

The error says "usb_configuration_settings_permission failed"

This actually appears to be a bug in the LG pm schedules, or Default LG permissions , at SOME level.
[OnePlus 6T  Questions & Answers] FakeGemstone:
My phone wasn't showing up in Windows Device Manager when I connected the phone to my PC via USB cable. I had deleted then reinstalled the USB drivers so I thought that was the issue. Still, I was able to issue ADB commands to my phone and when I switched to bootloader mode the phone DID show up in Windows Device Manager as Android Device --> Android ADB Interface. Also, when I switched to EDL mode the Qualcomm chip showed up as Ports --> Qualcomm HS-USB QDLoader 9008.

Then later on, when my phone was still connected to the PC I happened to take a look at the USB Preferences. They seem to default to "no data transfer". But when I selected "File Transfer" as the option, suddenly my phone showed up in the Device Manager as Portable Devices --> OnePlus <model number>. Connected with the File Transfer setting turned on, I still seem to be able to issue ADB commands to the phone.

Thank you, Masamune, that's a good point. I don't know how it got messed up in the first place --it had the yellow warning triangle right from the start, even before I did anything with it.

[ASUS ROG Phone 5 / 5s] anthropoidape:
Hey all, I am on the hunt for a new phone after four years with a Huawei Mate 10 Pro... still stuck on Android 8 but otherwise going strong.

I am having trouble narrowing this down, but Rog 5/5S Pro is ticking a fair few of my boxes. I like the flat screen, the good specs etc. On the other hand there are strong competitors like Pixel 6 Pro and S21 Ultra, or even Note 20 Ultra (snapdragon version).

I can get a 5S Pro (18GB/512GB) locally here in Australia for $1899 AUD, or pay a fair bit less for a CN version shipped from Hong Kong or China.

I have always had root on my Android phones and will probably want root on the new one.

So a few questions...

1. Do you recommend this phone?

2. Does it matter whether I get CN or WW version?

3. I have read some stuff about problems unlocking the bootloader, or unlocking the bootloader twice, etc. Basically I am usually content with a stock ROM plus root, is this going to be a problem for me?

I am not much of a mobile gamer, but I use my phone fairly heavily in general.

I am having a bit of trouble making a decision here....
[ASUS ROG Phone 5 / 5s] yurishouse:
1: Yes, I use 5sp, it's really nice phone to have aside from the lack of waterproofing.

2: DO NOT get the CN version, you'll have issues unlocking your phone and / or getting a network connection. Also the device will likely come with a Chinese fw if you buy it without modifications done by seller.

3: if you unlocked your phone then why lock it back.... And yes, you will sometimes have trouble getting the phone to unlock the second time after relock. But there's a guide here on how to fix it.

Stock + root is currently the only option anyway.... There's no ROM available atm. You can find patched boot images in one of my thread, flash it after unlocking, and just enjoy. You won't even need TWRP for anything... For now
[ASUS ROG Phone 5 / 5s] anthropoidape:
Thanks Yurishouse, good info.

I think I'm content to pay a bit more for a local version. Much better for warranty etc apart from anything else.

This has been a hard choice, but 5S Pro is my front runner, having looked hard at Pixel 6 Pro, S21 Ultra, Xperia 1 iii, Oneplus 9 Pro, and a lot else.

I am a bit worried about the low level of activity on this forum but that seems to be how it is for every device compared to three or four years ago, i guess things are different now.
[ASUS ROG Phone 5 / 5s] Prack:
Low activity is likely the cost and how difficult it is to get one. I've been trying to get a 5s pro from a non-scalper for months, was finally successful and ordered one off the asus store yesterday.
