Did you do a clean flash?
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Atwood001:
(I was on lineageos before)

Flash process 1-

Step 1. Twrp > Advanced wipe > select dalvik, cache, system, data, vendor > wipe

(Did not wipe internal storage)

Step 2. Flash calyxos.zip from internal storage.

Result- Stuck at bootloop for 5 min.

(Had to reboot to recovery again manually.)

Flash process 2 -

Step 1.

Step 1. Twrp > Advanced wipe > select dalvik, cache, system, data, vendor, internal storage > wipe

Step 2. Moved calyxos file from pendrive to internal storage. Had to mount usb-otg.

Step 3. Wiped dalvik, cache, system, data, vendor again just in case.

Step 4. Flash calyxos.zip from internal storage.

Result- Stuck at bootloop for 5 min.

Flash process 3 -

Step 1. Twrp > wipe > format data

Step 2. Twrp > Advanced wipe > select dalvik, cache, system, data, vendor > wipe

Step 3. Moved calyxos file from pendrive to internal storage. Had to mount usb-otg.

Step 4. Wiped dalvik, cache, system, data, vendor again.

Step 4. Flash calyxos.zip from internal storage.

Result- Stuck at bootloop for 5 min.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Dev_Mashru:
You seem to be flashing fine. Not sure why you are getting stuck in a bootloop. Only people who flashed DFE were facing this issue, but since you arent flashing that either, I'm not really sure. Which twrp are you using?
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Atwood001:
twrp-3.5.2_10-0-beryllium.img. Should I try with other recovery?
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] TioCareca:
That seems possible a vendor/firmware problem, try to flash stock miui first to recover all partitions data correctly, then flash calyxos...

Step 1. Twrp > wipe > format data> Advanced wipe > select dalvik, cache, data, internal storage > wipe

Step 2. Flash calyxos.zip

if bootloop just format data again...

Hope it helps...
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Zatsando:
This is exciting stuff, being able to port this Rom into Poco F1 is huge! However I 'm sceptical of using an unofficial rom for my main smartphone. No offence for the developer, though, I hope the Calyx OS team find his project and properly port it for poco f1 as an official one!
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] nolam10:
When i flash a rom i never wipe vendor.And now you should update the vendor lo the latest one before you flash again. never wipe vendor if you know its the latest.Afher installing the latest vender format data and reboot back into recovery and wipe dalvik cache system internal storage and data and flash from sd card or external storage .Another way is to restore the phone to latest manufacturer rom and the reinstall twrp and 100%clean wipe but don't wipe vendor.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Ajudia:
Calyx OS official only possible with device having secured boot means relocking bootloader after flashing Rom, which most device lacks except pixel phones and mi A1,

this rom rocks on F1 enjoy!
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Zatsando:
yeah I know that, but using and unofficial rom and most important of all, without making the code public is not safe for anyone. not to hate on the developer (I am a developer myself) but I try to use stuff that they are open source, especially when it comes to OS's. I really hope the dev releases the code so the poco f1 community (who I m sure it embrace this rom) can audit it and give their approval!
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Dev_Mashru:
First off, I dont see why using an unofficial build is an issue, its not that if it was official you'd suddenly know me to verify anything. That being said, as @Ajudia said, official isnt possible because F1's bootloader cant be locked after flashing a custom ROM. When it comes to open sourcing the code, I havent deviated much from the calyx source. In fact I have turned down multiple requests to add live display, as it would deviate more from the original source. That said, the only changes that were done were CAF additions to get it to boot and get everything working. The only major deviation is addition of QTI BT to the original source. All those were picked from LOS. Also the kernel is already open source. You are welcome to audit it and report back if you find anything. That said, I did plan to push the few repos where the code was changed, but didnt find enough time to push. If I find time in the future, ill push them. Also for all the ROMs out there whose code is open and have official support, there is no way for you to verify that the developer is actually using what he is showing. At the end of the day you have to trust the developer that he is indeed using what is shown to the world or compile the ROM yourself.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] TioCareca:
What's the difference between this rom and lineage with microg?

True question 😉
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Retrial:
With respect to the dev, tbh CalyxOS wihout the ability to relock the bootloader is pretty much useless for the nature of this ROM. (Bootloader can be locked only in Pixels and Xiaomi A2 devices)

I guess the build in Firewall and App Lock it's something make it stands out, otherwise it's like a pure AOSP ROM with microG.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] TioCareca:
I was thinking the same, that's why the question, the firewall and vpn was my selling point, but i think it can be done in all roms too...

Anyway thanks for the dev to give us another choice 😁👍
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Dev_Mashru:
I am sorry, but I beg to differ. While i agree that being able to lock the bootloader would make it much more secure, i still think calyxos is more secure because of the following reasons:

1. I have enabled DM-Verity which means that everything in the boot process is verified once the kernel is loaded, but if something before the kernel is loaded, it will probably be able to maintain that access. That said, it is definitely more difficult to get infected with something sophisticated that starts itself before the kernel than other more common attacks out that start after the kernel is loaded, which DM-Verity should prevent from happening.

2. Microg for LOS enables signature spoofing for all system apps (according to the FAQ on their website), which means a malware that manages to get system privileges could potentially be able to misuse the permissions. On the other hand, calyxos sandboxes signature spoofing to only the microg apps with explicit whitelist, which makes much more difficult to be exploited.

3. Lineageos builds are userdebug, while my builds are user builds. Userdebug builds have many debugging capabilities that "normally violate the android security model" (quoted from AOSP). Those debugging capabilities could also potentially add more attack surfaces making it less secure.

Some might even find the other features like restricting unknown USB, making a signal/ WhatsApp call directly from the dialer and other such calyx features useful.

Like I said in the beginning of this post, it is definitely not as secure as a device with a locked bootloader would be, but I have tried my best to make it as secure as possible.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Retrial:
Don't get me wrong. I like that POCO F1 has this ROM even unofficial. However all these features more or less can be achieved in other ROMs too. Having them ready out of the box is useful tho.

What I am trying to say is, all the hype about CalyxOS and GrapheneOS that makes them stands out is the locked bootloader which make them more secure. That's ofc unavailable for our device and I know you've tried to get it as close as you can.

With all that said, I would like to see this ROM staying alive for POCO F1 and to keep it up. Giving users more choices for ROMs is nice and I like to see people start thinking about privacy and security more.✌️
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Zatsando:
After using it for the last couple of days it is indeed very all in one out of the box privacy respected rom. The individual apps are not something that you can't build them your self, or download the seperately but its a very good privacy package. So far only revolut can't run (due to root), riot games and audible. Sometimes it might delay a notification also...

[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] TioCareca:
No, if you lock your bootloader with a custom rom, you won't be able to boot.

if you asking if the rom lock your bootloader, no, it won't.

[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Bandanaman:
I was using Calyx on a Pixel 5 and loved it until I developed PWM sickness and switched to LCD. Was so happy to see this Rom and grabbed a Poco f1 to install it. And I am happy to say it runs flawlessly! Connectivity, software, apps, firewall etc. Even my banking app works. Havent found 1 bug. Absolutely love it. To the developer - Thank you so much for your work, without people like you, people like me would be settling for the mainstream instead of enjoying the variety we're blessed with.

is this rom still supported? or will it be supported in the future?

[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] z4ck1n:
Calyos features are themself are the difference. eg.. MicroG integration is more hardened is Calyos.

I am not sure purpose of discussing pocof1 relock abilities, afaik no custom rom can achieve this for poco.

For PocoF1 users, looking for security & privacy ...this is the best comprised option you have.

@Dev_Mashru thanks
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Retrial:
Can you elaborate me how is difference? The only change they have made it's not on microG itself but on signature spoofing the ROM comes with, to allow only one program (the microG) and not other.

About relock, bootloader I think I already mentioned that here and that's the main reason I've made the post about CalyxOS.

Believe what you want, but it's already behind at security patches, and that's a security and privacy issue, don't you think?

With all that said, I am not against the ROM nor the Dev if it's actively maintained it, since it has some privacy apps by default to choose to save you few clicks.

But let's be honest CalyxOS and other similar ROMs like GrapheneOS(which is the best) are made for devices which bootloader can be relock (Pixel devices, Xiaomi Mi A2).

P.S: I don't want to defame the ROM or the Dev since I already said that it's good to have it on POCO F1 even like that. I just replied to you, because you chose to specific quote my post.

[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] li70:
Completely agree with you, on my point of view if the code is not public then it's not trustable "when not official". However the rom seems very good with those features. :)

I just bought this phone about 2 days, but it has poor signal, and now it cannot receive any signal with no network connection indicator, I even tried using e-sim but its just the same. I already tried factory reset, network reset, flash stock firmware via odin but no luck. Any help?View attachment 5308055
[Samsung Galaxy S21 Ultra] meowHelpMeRoot:
maybe it is just a problem with some sort of connection for the e-sim/physical thing, what is the carrier? please do not post your imei

also try turning airplane mode on and off
[Samsung Galaxy S21 Ultra] blackhawk:
Welcome to XDA🤗

Maybe be a bad sim card.

Sim cards can be damaged by ESD, handle it like a stick of ram. Never touch the contacts and at least discharge yourself by touching an earth ground before handling it.

Sim cards are good when they leave the manufacturer, a failure almost always is due to ESD damage afterward by the installer... just like ram sticks.

P

Access point names misconfiguration.

If it's a carrier phone like AT&T they will help you troubleshoot it.
[Samsung Galaxy S21 Ultra] amirage:
I can see 2 issues here: 1. You have dud sim or 2. You didn't pay your telephone bill...if it's 2, you'd still get a connection. Have you tried using a sim from another provider?
[Samsung Galaxy S21 Ultra] Beefheart:
Is it a brand new phone or second hand? If the latter are you sure it's not stolen and network blocked? The fact the esim also doesn't work would suggest this could be the case as it likely rules out a hardware problem with the sim or simcard slot.
[Samsung Galaxy S21 Ultra] NippleSauce:
Just an FYI, but I believe that this issue is tied to Samsung's latest update for the S21U. I pushed it through this morning and now whenever I disable my WiFi, I lose my cellular connection for about 10 minutes and only get it back after waiting, doing a reboot or turning WiFi back on...

Very strange...
[Samsung Galaxy S21 Ultra] enigmaamit:
If you bought it from official channels, raise a ticket for support with your Carrier or Seller. If you got it off e-bay or by other means, go back to the source and try to ensure it's not a stolen and IMEI blocked device. There are a lot of stolen phones floating around in the second hand market.

If even a clean ODIN flash isn't working, it's unlikely it's a user fixable problem so you'll most likely have to go to the service centre for this.

Try connecting to 3g/2g instead

should work if you have bad 4g connection in your country

Just by settings---> connections --->mobile network --> than change from 5g/4g... to 3g/2g and see if it improves😏

Hello everybody

I have an annoying problem with viber. When I send photos with my viber account, some of them move from gallery to viber folder with lower quality so I lose my files. I reinstalled the app, I made a hard reset to mobile several times but I cannot find a solution to the problem. I copy new photos to different folder before sending them from camera folder because viber deletes them after sending.

Does anyone else have the same problem?

[Samsung Galaxy Tab S7 / S7 Plus Questions & Answer] Siegemus:
Hello. This is my first ever post on XDA, so please excuse any mistakes. Recently, I have been wanting to install TWRP on my Samsung Galaxy Tab S7 (Model Codename: SM-T870), however, I haven't found any .img files available, either official or unofficial. I have been able to root it using Magisk and Odin, however. My tablet is currently running Android 11 with a build number of RP1A.200720.012.T870XXU2BUC6. From what I've read online, the "2" in the "T870XXU2BUC6" section of the build number means that the Bootloader is on Version 2, meaning that I can't downgrade to software versions with a 1 in the software name (i.e. with a Bootloader version of 1). This includes Android 10, and some older versions of Android 11, even if I use the latest version of Odin and if I'm rooted. I know how to install different distros and versions of Linux for creating TWRP from scratch if need be. If someone would be willing to either guide me through the process of creating TWRP for this device, or include a link to an already existing version of TWRP for this device (remember, Android 11, Build Number: "RP1A.200720.012.T870XXU2BUC"), I would greatly appreciate it. All I ask is that the guide(s)/tutorial(s) be in layman's terms, and be step-by-step. I am not very familiar with Linux Commands, so I would appreciate some grace when replying to this post, as I may not be able to understand some terms. Thanks! :)

There is a vbmeta_disabled.tar that worked for me on my T870. Also, in response to your May post about a guide to building TWRP for the device, I wrote one while I was doing my build. It is posted as a response to my TWRP thread here:
