I'm still using AT&T and T-Mobile on my AL00 without issuesView attachment 5232915View attachment 5232921

Agreed I am using mine on ATT without issue.
[Huawei Mate 20 X Guides, News, & Discussion] fitrockx:
Happened to me after testing my sim card in a S20 FE. When I put it back on my Mate 20 X the service got disconnected. Called AT&T they say because I need to update to a 4G phone. I told them that my Mate is 4G and they reactivated without issues. The rep that attended me didn't told me that Huawei was not being accepted anymore from AT&T, just that needed to make sure it supports 4G.
[Huawei Mate 20 X Guides, News, & Discussion] bigfire:
I did try it out with Tmobile later and had no problems, and the buyer hasn't reported any issues, so it sounds like just bad information. Thanks for the info!

kin USa idiots at ATT .. pss message to them from me pls !
[Huawei Mate 20 X Guides, News, & Discussion] CCJ22:
I got a text message today from AT&T saying "we're sending you a phone. if you don't activate it, we will auto activate it after 30 days and your phone you're using now will only be able to call 911"

This is a huge bummer.
[Huawei Mate 20 X Guides, News, & Discussion] AngelDeath:
I only got that they are retiring 3G, but nothing that says they are suspending supporting The phone as they have NEVER supported the phone, so thats a crock of crap. The only thing they can do is turn off the 3g band and if your phone doesnt use 4G then your SOL. Mate 20X uses 4G LTE so they cant touch me and if they do they have alot more to answer for.
[Huawei Mate 20 X Guides, News, & Discussion] shaolin95:
is Tmobile still going to keep supporting it?
[Huawei Mate 20 X Guides, News, & Discussion] shaolin95:
At least from a test

That is what I thought BUT I think I found the issue. If you download an app that check the band your phone is using, you will see that for CALLS the 20x with an ATT sim card, will drop to a 3G band not LTE!

Now, if I try a TMobile sim card and make a call, the phone still shows using LTE band so looks like people with TMobile will be able to keep the phone just fine.

I recently experienced the same thing on my Huawei Mate 20x evr-l29. Call AT&t and they unlocked the suspended account and explain to me my phone is registering as a 3G device. I asked them to look at my network history and they clearly see it's using the 4G LTE network without issues. The representative at tech support said they were noting my account to escalate a ticket to not shut off my device come February. She assure me it will continue to work but we will wait and see.
[Huawei Mate 20 X Guides, News, & Discussion] Epiphanysfi:
So I was told that, my wife's Mate 20 x had to activate the new sim card because 3G was tied to the previous sim. Was not the case and they suspended the phone number once I activate the new sim (they also sent a refurbished S9 with the sim). I had to call customer service and escalate for them to reactivate the sim card. I'm now waiting to call their "3G Sunset Department" to try to put my phone on a white list (1-800-880-8581). Seems they are only open during business hours so have to call back then. This has not been a good experience.
[Huawei Mate 20 X Guides, News, & Discussion] Epiphanysfi:
So I had a fiasco with AT&T. Props to the services techs that had to deal with me in store and over the phone. They kept their cool and customer service up there. I've just been trying to keep my cool over these two days spending alot of time going between different people and then also swapping to another sim being told that would fix it.

Mate 20X is no longer supported by AT&T. In the case of new customers. Basically they have black listed the model and IMEI numbers of these phones. So when a sim card is inserted the phone line associated with it will be suspended.

To get around this you have to call customer support to have them activate the SIM card so that it will work. Phone calls and Data will work after that.

For my wife's phone I used to have unanswered calls and busy get forwarded to her google voice. With the problem above with the IMEI number being technically blacklisted I was not able to set up google voice again. Took me a couple of calls and an escalation to an advanced tech to have them set up call forwarding from their side. After that the phone works as before for now until they shut off 3G data in February.

Educational moment: After I did some searching online and also a good talk with that advanced tech I found out the reason that this phone is identified as 3G. I blame AT&T for the lack of educational material being sent out and the training of their staff on the phone.

Good article explanation: https://www.androidauthority.com/volte-att-t-mobile-1148654/

The Mate 20X is a 3G voice phone. Even though it is a 4G LTE capable phone it is not a VoLTE/HD Voice phone. Hence the reason why this phone was identified as a 3G device. So basically when the cutoff date comes in February, the phone will not be able to make phone calls or receive texts. Technically it should still be capable of using the 4G data but take this with a grain of salt because they basically blacklisted the IMEI/Model of this phone. So they could just force these to not work anymore.

Here's a list from AT&T that will still work after the change to 3G: https://www.att.com/idpassets/images/support/wireless/Devices-Working-on-ATT-Network.pdf

This is their current compatibility list for unlocked phones: https://www.att.com/idpassets/image...Capabilities-Unlocked-Devices-ATT-Network.pdf

Meh, actions have consequences...
[Huawei Mate 20 X Guides, News, & Discussion] jackfrost7:
FYI (and I know this is really a late reply), this is incorrect if you were lucky enough to have unlocked the bootloader on your Mate 20 X (EVR-L29) phone (or if you can do so if the opportunity ever arises again in the future).

Thanks to someone else on this forum (posting about a different huawei phone, I've lost the original poster), I've discovered that it IS in fact possible to enable VoLTE on AT&T (ATT) if your phone is rooted.

Before making these changes attempts to make or receive calls will fail even though data and texts will be working and there is a 4g signal symbol.... and going into settings -> wireless & networks -> mobile network will not have the necessary "VoLTE calls" option to turn VoLTE on.

Simple way to enable VoLTE on rooted Mate 20 X on AT&T:

adb shell
su
mount -o rw,remount /
echo "ro.config.hw_volte_on=true" >> /system/build.prop
echo "ro.config.hw_volte_dyn=false" >> /system/build.prop
mount -o ro,remount /

Restart your phone.

The "VoLTE calls" option will now show up, and can be turned on... after which phone calls will again work on the Mate 20 X on AT&T.

I hope this helps someone like it helped me to figure out, even though I know unlocked bootloaders are rare on this phone.

I also couldn't find another phone this size that would work on AT&T (aside from fold ones that I don't want) so really happy that this ended up working.

Magisk updater installed Magisk & said it needed to make a change to continue the update. I clicked the Reboot button. The phone boots into TWRP. I reboot & it goes into TWRP. Repeat.

How can I recover, preferably w/o losing apps & most preferably w/o losing data like pics?

I'm using Android 9 rooted.

restore then

You can also try magisk uninstaller which comes with magisk on github(seach github magisk the uninstaller is in assets)

I was able to get back to TWRP by switching slots. Backup fails because Data is encrypted & TWRP is not prompting for PIN. I'll try using the Magisk uninstaller tomorrow (past bedtime). Long shot.

Open to other approaches. Thanks for your help.
[OnePlus 6T  Questions & Answers] spinergist:
Facing the same authenticate error when trying to boot into twrp.img. I also don't know how useful twrp will be on the other slot if it can't decrypt the data from there so stuck at this stage too.

@kamiller42 Did you manage to resolve this with the Magisk uninstaller?
[OnePlus 6T  Questions & Answers] kamiller42:
Nope. I tried getting by by flashing just the boot image. It erased data & everything, so I flash Android 10 again & re-rooted.
[OnePlus 6T  Questions & Answers] spinergist:
Did you flash all partitions?

Is there a way to only flash the boot partition, then boot into twrp.img, flash that, then reboot into recovery to decrypt the data? I care more about recovering my encrypted data than getting the phone working.
[OnePlus 6T  Questions & Answers] kamiller42:
That's what I thought. All was lost when I flash boot image. Technically, I flashed the fast boot partition from this post. https://xdaforums.com/t/rom-stock-fastboot-op6t-stock-fastboot-roms-for-oneplus-6t.3862516/

Have never had an issue went to update to latest Magisk app, followed directions and restored it first, everything seemed fine, then went to flash Magisk itself from the app (Direct install) like always, didn't seem to do anything, checked the Magisk log, said unknown image type and that it failed, rebooted phone, phone will now only reboot into fastboot mode. Not the quality I've been accustomed to and certainly does not belong in the stable branch. Now can someone please tell me what I should do to fix this hot mess?

I got same problem. Fix was install again whole factory update zip file which I received during last phone upgrade from vendor. (oneplus 5T)
[Magisk] PrussianWolf:
First: When you're in fastboot-mode then use "fastboot devices". ;)

You don't need the recovery to solve your problem!

1. extract the "boot.img" from an existing original ROM on your PC

2. use fastboot command to flash that original boot.img

3. reboot to system - your phone will work well as before

You can root again, but use Magisk 21.4. There seems to be something buggy in version 22.0.

Version 22.0 worked properly with my Xiaomi Note 10 Pro (Android 10) but it didn't work with my Xiaomi Mi 10 Lite 5G (Android 11).
[Magisk] Oliie23:
You mean a full OTA?
[Magisk] erOzeOz:
Either you flash a full image of your existing ROM, or you extract the boot.img from the ROM archive (i.e. .zip) and flash it (as boot)

yes, full OTA. I did not play with restoring it from TWRP and I had no idea which part is affected. But Phone was not wiped, it kept everything.

Welcome to the "magisk app" :ROFLMAO:
[Magisk] teknomedic:
Having same issue, unsure how to proceed. I'll start my own thread if needed.

LG V30 (US99830b), Android 9, Security patch August 1st 2019, Kernel 4.4.153

have had Magisk installed for a long while and have done many updates without issue. Previous version was 21.4. Got the notice to update

Unhid Magisk manager as directed and Ramdisk shows "YES"... and then updated manager to v22.

I then tried to update Magisk itself to v22

Selected "direct install" as I've always done in the past.

Seemed like nothing happened... backed out, tried again.. .still nothing. tried a couple more times and then just set it down... then I noticed it actually did something and gave a message stating something like "your device needs additional steps to complete update... proceed?" ((I'm not 100% on the message as I only read it once))... then clicked "YES".

Phone restarted into "fastboot" mode... I can power off or restart, but both bring me right back to this screen.

I can load TWRP and select "SYSTEM" to boot, but that only brings me back to the fast boot menu.

I don't want to mess with this further without direction as I don't want to lose my data on the phone and am going to be pretty upset if this means I'll be having to reinstall everything at this point... WTF kind of update is this??

The only reason I have this much information is that I have 2 (two) identical LG V30s (rooted and updated the same way with Magisk and TWRP) and only updated one at this point... certainly not going to update the other one until this gets sorted.

I'm basically stuck with a brick at this point...

Thank you for any help

So, am I understanding that this update killed by boot image?... so...I need to obtain my un-altered boot image from inside the main phone image I used (must have been a couple years ago now?) and then push the Magisk v22 update directly onto that using TWRP to "fix" this... which won't touch my system image?

The real trick is going to be figuring out which download I used from here all those moons ago, lmao. I know I did a backup as well, but I think that was only from the factory image and not.... I think... from the custom ROM I downloaded here.

...I'm off to bed... I'll hope for some clarification by the time I wake up, lol and hopefully my brain will be working better then too.

lol ..Magisk 22 is not working with my Android 11..

edit/ just renamed Magisk-v22.0.apk to Magisk-v22.0.zip and flashed in Recovery and it Works :)
[Magisk] Didgeridoohan:
That's the gist of it. There should be a copy of your untouched boot image in /data/magisk_backup_<sha1 checksum> (Magisk saves it there when patching).

https://www.didgeridoohan.com/magis...ootrecovery_image_for_the_Magisk_app_to_patch

What you can do is just let TWRP flash the boot image (just like you would a zip, but change to "Install image" and then pick boot when asked what partition to flash to). After that you can flash the v22 installer (just rename the .apk to .zip) and everything should be working.
[Magisk] marulinko:
I got broken phone today morning. What I have common with others is that I had hidden Magisk. I followed instruction to "unhide it" and the I tried install it via Magisk manager and problems were similar like were decribed by teknomedic.

My fix was flash latest OTA image which I received during last upgrade.

Now, just few minutes ago I used Magisk 22.apk which I renamed to zip and flashed it via TWRP. And It worked on same phone which got problems morning. I think that problem is not in magisk app, but method how it handles the unhiding magisk and install new version afterwards. This should be tested. Or do not update it via app itself from android. Use installation renamed magisk22.apk to magisk22.zip from TWRP.
[Magisk] teknomedic:
Okay, so I dug into data and found two folders with Magisk_backup_checksum....both seemingly empty. Thoughts?
[Magisk] A.Ahmed79:
I updated magisk to version 22.0 today and my phone stopped working now.

The update was successful AFAIK and then when the phone rebooted, it got stuck at the loading screen showing the samsung logo. and its stuck there since then.

When i press power+vol down button, it just reboots and hangs at the same place again.. can't even switch it off.

Please, please someone help me get my phone to working back again..

I'm fairly new to rooting, just managed to install a custom rom and rooted the phone using magisk and now its in an unusable state.

any help with be greatly appreciated. :cry:

(using samsung S8+)
[Magisk] Didgeridoohan:
In that case you'll need to find the boot image elsewhere.
[Magisk] teknomedic:
Are boot images unique per phone? I'm assuming I could perhaps backup my boot image from my other rooted V30 and then transfer it over??
[Magisk] teknomedic:
Okay... two things...

first, I "backed up" my other V30 boot with TWRP and copied those over to my bricked phone. Yet, when I try to use restore it asked me to select where to restore to... except it doesn't give me any options to select.

Also... I also just tried file manager in TWRP and my backup folders actually do have a file called "boot.img.gz". I'm guessing they looked empty to restore because it's looking for an image or zip.

I assume I can just rename that file to simply boot.img and all will be good?

Also, also... is there a way to tell which image I should restore between the two folders?
[Magisk] teknomedic:
eesh... okay, so I renamed both files to simply "boot.img"... tried installing both to boot and yet... directly back to fastboot menu. :(
[Magisk] ineedroot69:
ohh no its seem that most people fixing there issue by just flashing the stock boot.img of your device
[Magisk] ineedroot69:
don't do that each boot.img is unique for every device model flashing boot.img from different device could make your phone permanently brick
