anyone could help?
[Samsung Galaxy Watch 4] adfree:
Still no real idea...

You could check if you have bootloader unlock in Reboot menu...

Unlock

This do some "special" Factory Reset...

Later you can lock again...

IMHO this not affect Knox...

Best Regards
[Samsung Galaxy Watch 4] adfree:
Oh "great"...

Checked my SM-R860 with HWH3 for OXA (DBT)...

Seems "normal"... so "they" disabled AP Mode...

Will test my SM-R875F with HWI1...

No idea if Bug or Feature...

But IMHO "S.msung Feature"...

Best Regards
[Samsung Galaxy Watch 4] adfree:
Hmmmmm...

My SM-R875F with installed HWI1 Firmware looks normal...

Not complete tested with netOdin...

So we need to wait for next Firmware Update... to see if mistake or "feature"...

Best Regards
[Samsung Galaxy Watch 4] SMKAROFIR:
Maybe it's a firmware issue, because I've had a few friends who also had this problem flashing from CHC firmware to XAA firmware.

I followed your instructions and did a factory reset but it is not ok, so I'll have to wait for the next firmware update, hope it is not too long.

Thank you for your response.

I have the same problem, did you find a solution?
[Samsung Galaxy Watch 4] SMKAROFIR:
Good news, the latest firmware update resolves this issue

you are now able to access AP Mode? I really need to flash my CHC Firmware Watch 4 to XAA or something
[Samsung Galaxy Watch 4] SMKAROFIR:
Yes, I just updated the latest firmware today
[Samsung Galaxy Watch 4] superevans:
That's awesome. Are you planning on flashing from CHC to XAA now? or from XAA to CHC?
[Samsung Galaxy Watch 4] SMKAROFIR:
No, the phone I am using now is A52S that does not have CHC version
[Samsung Galaxy Watch 4] superevans:
Ah okay then. I really want to downgrade/flash to XAA once the CHC version of the Watch 4 is updated. The waiting game continues
[Samsung Galaxy Watch 4] SMKAROFIR:
You can try to do this, my watch was CHC version, and the XAA version I flashed is lower than that
[Samsung Galaxy Watch 4] superevans:
If you don't mind me asking, can I ask for more info on how you did this? I haven't tried to flash anything on my watch, so i'm just really nervous i might brick it. Did you flash the EVA8 OXM firmware? on your watch?
[Samsung Galaxy S10 Questions & Answers] ZG_DEV:
For now I only know how to turn off the phone while it is in bootloop state

Press all buttons once "Samsung xxxx Secured by knox" appears, it will shutdown after 10-13 seconds, You can try booting into secure mode, magisk will detect that you have booted into safe mode so it will turns off all installed modules until you turn them on.

Hello ErikUden, don't forget to connect it to the PC.

On the video there are things that do not already unlock bootloader, then don't forget that once magisk has modified AP official rom transfer it with adb push then use the 4 files BL- AP magisk patch..... tar- CP-CSC not the home.

After starting as in the first day, install Magisk, follow the installation message, activate Sygisk, then for the modules, look on this forum, it explains everything.

Hello, the answer is on this forum in magisk.

There must be at least several members here who have had your problem.

Magisk General Support / Discussion

This is the place for general support and discussion regarding "Public Releases", which includes both stable and beta releases. All information, including troubleshoot guides and notes, are in the Announcement Thread

xdaforums.com xdaforums.com

On your video the explanation is better to go through the tutorial written there you have to make a bootloader before, look here to understand how to root with magisk https://topjohnwu.github.io/Magisk/install.html

the solution is simple, restart the download mode flashed with the official Odin firmware, put the 4 files BL-AP-CP-CSC and not the CSC home.

Once restarted as in the first days, follow the installation of magisk
[Samsung Galaxy S21 Ultra] macgd016:
I'm looking to buy an unlocked S21 Ultra SM-G998U to use in the UK. I see from the specs that the 998U 5G bands are different from the UK 998B version so I'm concerned that it won't give me 5G.

Having said that I see no comments online that say there are any issues and I note that the USA FE version, that has the same CPU etc as the 998U, does support the UK bands so I'm wondering if the stated bands for the 998U are more to do with certification than a hardware difference.

Does anyone have personal experience of using any of the USA S21 models in the UK
[Samsung Galaxy S21 Ultra] iron@ss:
According to kimovil, the U.S.A. model of the S21 Ultra, SM-G998U, will not be compatible with U.K. and European 5G networks.

See... https://www.kimovil.com/en/where-to-buy-samsung-galaxy-s21-ultra-256gb-sm-g998u
[Samsung Galaxy S21 Ultra] macgd016:
Thanks for your reply.

Yes I have been looking at Kimovil which is where I also found that the USA spec S21 FE, with the same chip set as the S21 Ultra, supports most of the UK bands.

See.....

https://www.kimovil.com/en/where-to-buy-samsung-s21-galaxy-fe-5g-na

I spoke to Samsung support in the USA yesterday who told me that all unlocked USA spec S21 phones will work worldwide including 5g which is why I wonder if the bands shown on the spec sheets are more to do with certification than technical constraints.
[Samsung Galaxy S21 Ultra] iron@ss:
That is the only information that I know of to go on. Bear in mind that a U.S.A. model phone will not be covered in the U.K.'s 2 year warranty and that Samsung U.K. may not have the parts to repair it. There are differences in hardware I am afraid. The Exynos CPU is on UK models and not Snapdragon also no mm wave for 5G. Normally, I would recommend getting a device from the region that you intend to use it in primarily.
[Samsung Galaxy S21 Ultra] macgd016:
I would normally do that but being stingy I'm not prepared to fork out for a new S23 as there are plenty of unused S21 Ultra SM-998U available here in the UK and from Hong Kong for less than a third of the cost. The only real question is will they work here 🤣, Samsung Support say they will, the sellers say they will but the specs say otherwise 🙄 so I was hoping there would be someone here who had personal experience of using one in the UK
[Samsung Galaxy S21 Ultra] coolopj:
i live in france and i'm using S21 Ultra SM-G998U1. initially my phone was only working with the mid 5G bands then i came across a tutorial on this forum to edit the 5G bands to work with all the 5G bands available, also it would be able to work with all the 5G bands around the world.i believe if u buy and follow thesame tutorial you'll be able to use all the 5G bands available in uk. i attached the 5G speed am getting now
[Samsung Galaxy S21 Ultra] macgd016:
Thanks for you reply @coolopj this sound encouraging!

I have read a number of (very long threads here on the subject but it wasn't clear whether the SM-G998U could be made to work on 5G in Europe but your experience seems to say it can 😁

My understanding (which is quite likely to be wrong!) is the most commonly used band in Europe in n78 which is not on the list of bands supported by the 998U which raises a couple of questions:

1. Is the 998U capable of supporting n78 or, as as seems to be the case with the USA (U) S20 Ultra, the hardware doesn't support n78

2. Is there a difference between the 998U and 998u1 as far as enabling 5G bands

Any thoughts?
[Samsung Galaxy S21 Ultra] coolopj:
1. Yes it supports N78. Check from the screenshot i attached to see all the bands

2. There is no difference between 998u1 and 998U. You can interchange the firmware, meaning you can flash U1 firmware on U or vice versa.

[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] TurboTronix:
Is there a way to unlock the bootloader of the SM-G988U1? I don't see the "OEM unlock" under developer so I can't enable it. Also, my phone does detect any SIM cards nor it can work with an eSim. It's a demo phone that I was given so not even sure it was meant to work as a regular phone (imei: 0000000000)
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] Rajarshi Khatua:
There are several methods to consider, and it's important to note that this process involves trial and error:

1. Remove your SIM card and restart.

2. Turn on mobile data and restart.

3. Perform a factory reset on your phone.
[Redmi Note 10 Pro] Likeusb:
Title self explanatory. I've tried Orangefox and TWRP, neither worked. I've tried adb sideloading and putting on sd card, nothing worked. With sideload, it goes through the entire installation normally and takes the usual amount of time, but doesn't actually put any files there and it doesn't install the rom.

So far, I've tried resetting recoveries by going back to MIUI EEA with Mi Recovery, that didn't work. I've tried fastbooting EEA and locking bootloader (Not turning off the Allow OEM unlocking toggle, but rather the flash_all_lock.bat script)

Nothing seems to work so I am going here as a final resort. I'd love to be able to put HyperOS on mine to test it, but can't and custom recoveries just don't install roms.

Any advice?
[Redmi Note 10 Pro] Laptapper:
After installing orangefox you've format data with typing yes?

If not you have to do it and afterwards flash fw, then ROM and again format data with yes in orangefox. Last step reboot system and wait some minutes
[Redmi Note 10 Pro] Likeusb:
Yeah I do that. What's fw, btw

But let's say I didn't, I:

- Go into OF12

- Format data

- Sideload ROM

- Format data again

- Boot into system

And this would make it actually work, right?
[Redmi Note 10 Pro] Laptapper:
Fw = firmware

Necessary for some ROMs

Check ROM installation manual
[Redmi Note 10 Pro] Likeusb:
I see.

I'll try HyperOS port install which requires nothing more other than a custom recovery.

To my knowledge EvolutionX doesn't require custom firmware (or if they do there's no files for it) and MIUI EU doesn't work either. It's only MIUI official roms that actually sideload correctly.
[Redmi Note 10 Pro] Likeusb:
Right so I've tried installing via TWRP and it says:

Failed to mount '/system_ext' (Invalid argument)

Failed to mount '/product' (Invalid argument)

Failed to mount '/vendor' (Invalid argument)

Failed to mount '/odm' (Invalid argument)

Rebooting anywhere also says that no OS installed despite completing the sideload.

PC Shows Internal Storage as non existent

Pre-initial format data it shows up as usual, then disappears
[Redmi Note 10 Pro] Atrumitos:
I'm assuming latest recovery is installed, as per ROM instructions.

Format data and directly after formatting, reboot into recovery.

When connected to the PC with MTP active, internal storage should appear. Transfer the required files.

After rebooting into recovery, follow instructions. Normally firmware first, then rom.

Boot into rom and you can install kernel afterwards, via recovery.
[Redmi Note 10 Pro] Likeusb:
The way I fixed it is by disabling MTP on the affected partitions, but this is probably temporary.

After disabling and sidoading, should I turn it back on or just keep it as is?
[Redmi Note 10 Pro] Atrumitos:
I'm not even sure what you're trying to mount with MTP enabled and why it's preventing sideloading.

Honestly, the best thing you can do is leave MTP settings default, transfer the rom to internal storage and install it as per instructions, via the recovery.
[Samsung Galaxy A50 Questions & Answers] cactus018:
Hello everyone,

I own a Samsung Galaxy A50 (A505FN) phone, but it have some serious issues.

1. First, I can't boot it up because of "Custom Binary (VBMETA) blocked by OEM Lock" error. (yes, I custom rom it then locked it to force a factory reset it because it had issues, and this was an attempt of mine to reset the phone - horrible choice)

2. I can't unlock the bootloader without actually booting the operating system.

3. When I try to boot into Download Mode by holding POWER + volume down, the phone just try to boot normally and fails. Also, trying the USB cable method also doesn't work - the phone still try to boot normally.

4. When I plug in the USB cable, the phone seems to charge, but it doesn't display any charging animation and instead try to boot and fails.

So, the only thing my phone can do is to attempt to boot, display and error and turn off. I can't boot into Download Mode. I think that's because the bootloader is damaged.

So, what could I do? Is there any way to rewrite the bootloader? Or maybe the bootloader is fine and there's a different problem? I would really appreciate any help.

[Samsung Galaxy A50 Questions & Answers] {Temp_User}:
hello, Please proceed with caution as my memory is fuzzy on what i did to fix this simial problem

I will assume that this is your first time installing a custom rom, so bare with me if i do mention details that you are aware of .

I will also assume your goal was to install a custom rom and that you are, at the time of writing this, that your system is running the official stock rom for your device based on your region.

Requirments:

working windows machine (of-course)

usb type-c cable

patience..

odin

stock firmware (too lazy to provide sources, google it)

Now for the fun part:). (take caution and do not skip)

1. switch off phone. (use whatever means is necessary.)

2. Attempt to boot to Download mode (if you managed to do step 1, then connect your phone via usb cable to computer and see if the charging animation shows up on your phone's screen)

2.1. If it did, then congrats, your phone isnt completely dead. Now proceed to disconnect the cable from the computer. Long press the up volume and down volume button and connect the cable again to your computer. This should immediately boot into download mode

3. Open odin from xda_source and check if the device shows up. Do not touch or attempt to change the default options. Install your firmware and wait for the phone to reboot automatically. You should now be good to go.

If the above fails, use the software provided by samsung called, smart switch (again, google is your friend)
[Samsung Galaxy A50 Questions & Answers] cactus018:
Hi, thanks for your reply!

It seems that the bootloader was fine and the culprit that was preventing me from starting the Download Mode was a damaged volume button - but I replaced it. Afterwards, I was able to start the Download Mode. I flashed the stock ROM and now the phone is working just fine.

Thank you for your response anyway. 🙏

Hi there!

So I'm unable to turn on OEM Unlocking, so my phone is locked under the Spectrum Mobile operator. But Google shows it as a "Fi" (global) version, so it needs to be unlocked, doesn't it?

Also, I can't contact Spectrum as they don't have an email and only accept chat from customers (I'm not a customer). Is there anything I can do with it?

Usually, if a mobile carrier locks it, it's due to not having paid off the phone. I don't believe there's anything you can do to remove this. Keep trying to get in contact with Spectrum
[Google Pixel 7 Pro] xeanoff:
This phone is not new, and I bought it through an intermediary. I understood the risk and I was warned about this problem, but I was jsut ly curious to know if there was anything I could do about it.

Unfortunately, I do not have a US phone number to contact Spectrum Mobile.

Anyway, thank you for your response.
[Google Pixel 7 Pro] scorpio76r:
Sell it on swappa.com you will not be able to unlock the Bootloader. Same issue happened to me months ago and, luckily I was able to get another one that wasn't carrier locked. I had never heard of Spectrum till this ordeal happened.
[Google Pixel 7 Pro] simplepinoi177:
Supposedly as long as you pay off the device, they'll send the signal over to allow the OEM unlock to be available.

But since you just said now that you got it from someone else, I do recall a situation (I might've @scorpio76r for all I know) where a person also got it second-hand and tried to speak to Spectrum and they said that they'd have to open an account with them or the phone needed to be connected to an active account with them.

But maybe @scorpio76r can tell you how he got in contact with them since you are having issue with that. Or, maybe, you can open an account with them and pay off the device -- you'll have to compare how much of a loss it will be selling on Swappa and then purchasing an unlocked device (even if it's not a P7P; but I imagine you can fennagle your search to mitigate the least amount of loss that way) vs. paying off a month and whatever outstanding is on the P7P....
