Caught in bootloop when reaching UI - Xiaomi Mi A1 Questions & Answers

I finally give up. I had lineage 15.1 running on the device and decided to upgrade to a pie based rom. So I flashed november firmware, rom etc. then I only had 3g. Now I decided maybe I need to flash latest december firmware so I flashed the 10.0.3 firmware zip and lost my sim card completely. I reflashed the november firmware. This made the device bootloop so I decided to flash stock november rom again and start all over. Now it's independent of the rom it's running it boots until the sim pin dialog, i can even press some numbers but it just reboots after a certain amount of time. Access to fastboot works fine so any idea how I could fix this would be greatly appreciated.

Looks like you got a corrupted EFS partition. If you have a TWRP backup for that, just restore. And if you don't, there is a thread in the Mi A1 forum about restoring EFS when downgrade from Pie.

First of all try to disable SIM Pin Lock from another phone. It was a bug from previous releases.
Second: never downgrade from Pie because it will causes issues and potential corruption.

But is downgrading from a custom rom comparable? And the firmware zips only have modems and bootloaders don't they? I am always struck how difficult the a1 is compared to my pixel 2

Well, you upgraded to 10.0.3.0 so you must use only that Pie firmware for now

Phone keeps rebooting and doesn't detect sim cards

Hey guys, I am facing a weird problem.
I was running the January patch, rooted with magisk, but I was facing some problems so I decided to return to the December Oreo patch.
I flashed the official patch (xiaomi firmware site) and I did a clean flash but after I flashed it when my phone booted it wouldn'1 detect my sim card and it reboots every minute and it's unusable because it keeps rebooting.
I tried flashing the January patch again but the same problem remained and it wasn't fixed.
I tried returning to the Nougat but when I flash the official firmware image, my phone enters a bootloop and doesn't start.
I don't know what caused this problem but I need help.
Update: wifi doesn't work either.
Try to flash the .18 nougat build with miflash, if I remember right it maybe could fix your issue. Nothing to loose anyway and do a clean flash.
Flash persist.img from August build, I'm sure it'll work.

No signal / IMEI after flashing Superman Rom

Hi Guys, hopefully someone will be kind enough to help me out here!
So I flashed my S7 Edge with Superman Rom a week or so ago and loved the Rom itself, however all I have got since is no signal, no imei, and won't read my sim. I've tried everything I can 're flashing Rom, trying to replace efs file (no backup as it got deleted ☹) and tbh I really haven't a clue what else to try.
I did try to refresh a stock nougat Rom through Odin but this now fails due to boot.img ?
So bloody lost.
If anyone has any ideas what to try I would be really greatful.
Cheers
Matt

Thank you mate! ...seems that the firmware I was flashing was not the newest version so couldn't update the boot to flash. Downloaded most recent Oreo and it flashed through dirty. Had to then flash TWRP and new root before installing would complete past the dreaded 'No Command' with yellow triangle screen! (Probably my fault for dirty flash - but just incase yours doesn't fully wipe if you get same problem as me). Rebooted and Oreo installed no probs and both my signal and IMEI have returned!
Custom ROM flashed and all still working no probs.
Much appreciated for the help!

Can you tell us more?
How did it start?
Did something happen to it, or did you just notice it is not connecting?
The most easy things first, is your sim card correctly in place?
Which ROM are you on and have you reflashed it?

The phone started with problems since I upgraded to Android Pie, I have taken care of it very well but I do not know if it is a hardware failure, but note that in baseband turns out to be unknown, I installed several stock roms from fastboot without any success, also I thought it would be a problem of the EFS partition, but everything is fine I even took a backup in case the doubts, what could happen?

Did you originally update via OTA, meaning, was it the official update?
Then when you noticed it's not working, you tried to flash several stock ROMs?
One possible problem that comes to mind, is that for some reason, you have the wrong radio/modem firmware. That can happen for example, if you have flashed a ROM, which is not meant for your region.

Yes, upgrade to Android pie via OTA
I already put a stock rom of the same region, following each fastboot command one by one, but everything continues the same, I even installed RROS 7, to see if at least it turned on the wifi, and it is in bootloop.

Go with the modding guide index: how to restore stock ROM etc., and flash a stock ROM that you know will work. Flash the radio/modem file too, and make sure it's the correct one.
Just to say, I had connection problems too, and in the end they were because the sim card did not latch correctly in place i.e. was not correctly in place.

Great that you have an idea. ?
Here's an idea: take a backup of your current config in twrp, move it to the computer, take a copy. Replace the files in that copy with the ones that you want to flash.
Did you mean this? You are aware that you can try different radio/modem files through fastboot, not having to flash everything else every time? That said, go with your idea. ?

Ok, but WiFi should work even if there is no mobile data available.
I probably can't help at this point, apologies! My suggestion is to flash a stock ROM, lock the bootloader and send the phone for repairs. There could be a solution to this, but I'm out of ideas. ?*

Hello, colud you solve the problem? Because I am havig a very similar one...
Hello group friends, I'm new here. I have a similar problem, I was using the Havoc 2.4 rom, when upgrading to 2.6 I no longer recognize my SIM card and the wi-fi does not connect, I can not install another rom anymore, nor rom stock, recovery TRWP has been replaced by the Havoc and the Wipe System function does not work, and for a few days you can not stay in recovery mode anymore, it restarts every 3 seconds, not the time to click the options. Can someone help me. I'm without a cell phone, and I need it.
I have a similar issue after flashing the latest firmware. SIM goes to "SIM locked" every ten seconds or so, and Wifi drops at the same tie. It's like networking is being reset every 10 seconds. No network settings I've tried change that.
I've flashed several stock ROMs; the one I had previously, newest, oldest, both for RETEU and retail. I used Lenovo restore to upgrade but that resulted in soft brick, after that I flashed the latest firmware via Fastboot and that's when the problem started.
With Oreo, wifi and cellular don't work at all, nothing detected. With Pie they're connected and dropped in a loop. I can't help thinking that the Lenovo restore broke this somehow, but modem files have been reflashed several times after that with no change. I'm not getting the baseband error.

I have the exact same problem, I wasn't able to repair it so I sent it to service and tomorrow they will try to fix it for $35. The problem with goign back to previous versions is that you loose the IMEI and MAC . The problem with the pie version I believe is the baseband. If the service is able to fix it I will post the solution here for you to fix it .

I believe you already tried puting it into bootloader mode. If that's the case, I had a similar problem recently an it solved alone, I let it loop for a while and suddenly fell, into dtock recovey, i factory reset (with stock recovery) and somehow stock was booted ( i believe it was because it was in inactive slot).
Hope this helps you

I am still working on this, I actually did this to a work phone (I had permission to root/unroot). Something that has helped me so far is just getting familiar with the whole flashing process - https://android.gadgethacks.com/how...actory-images-android-using-fastboot-0175277/. I think from this article the problem lies in the modem/radio rom. That *should* be the only thing you need to flash on. However, I have noticed with a lot of roms on here, a modem rom is not included on the stock firmware. But that needs to match well to your phone from what I understand. I have tried a few modem roms already, unfortunately, but no luck.

Unable to fix/restore IMEI and Wifi after flashing Lineage 16.0, backup available

I originally posted this on the Lineage 16.0 thread, but I figured it might not hurt to post this in a stand-alone thread.
I'm having some issues with the baseband/wifi after successfully flashing Lineage 16.0
I did do a complete nandroid backup in TWRP before flashing the copy-partitions-ab.zip, and I followed the instructions at the beginning of the thread, sideloaded the ROM, and it booted just fine, but I kept getting "No SIM card inserted" . Now when I try to restore the EFS and Persistent partitions from the backup, I still don't get a working baseband...
I even tried restoring the backup I made previously, but I still was not able to make the baseband work. I then tried flashing this stock ROM: https://forum.xda-developers.com/g6-plus/how-to/rom-official-stock-pie-9-ppw29-116-11-t3892935 through fastboot, and since this hasn't fixed the problem, I tried restoring the EFS and Persistent partitions from the backup, but still no go.
Does anyone know what I can do to fix this? Not being able to receive/make calls or connect to a wifi network basically renders this phone useless...
Seems the problem was that I didn't flash the correct version of the stock rom. The linked thread has the first version of the Pie stock OS, while previously I updated the phone two times after the Pie update. Flashing the latest version of the stock rom brought back the IMEI numbers and the WiFi MAC address. After seeing that the problem was fixed, I decided to try flashing the Lineage ROM, and that worked as well. Not sure what happened, but I'm glad I was able to fix it with no hassle.
You can get all versions of the stock ROM here: https://mirrors.lolinet.com/firmware/moto/evert/official/RETEU/

The restore of the stock firmware can be done through fastboot and you don't need to unlock the bootloader for that. Just search on Google and you'll find a lot of guides to do that

SM-T290 Custom Roms??

Hello. It's been a year since release of this tablet, so Is there any custom roms available for the SM-T290 (Galaxy Tab A 2019 8 inch")? Like Lineage OS?
Thanks.

Hello friend, unfortunately there is only one rom, made by a member of the forum, an improved version of the stock, but you can try a rom via treble, since our device supports updating by this method, I am testing some myself.
I have a T295 (the only difference is that is has mobile data afaik) and would also like to get Lineage on it, since the stock rom is extremely slow, even with very few apps, disabled animations and whatnot.
How would installing via Treble work on Samsung devices, especifically this one? @Reick7
EDIT: nvm, found it, seems to support both T290 and T295 as in: https://github.com/phhusson/treble_experimentations/wiki
I'm going to try and install it and report back!

well, i haven't tested it for a long time, as i've passed the tab to someone else, but the one i tested doesn't work as well as i expected, it was the Resurrection Remix Q
@Reick7 Couldn't get it to work, sadly.
I tried to install Treble but it hangs on the initial boot screen aka "Samsung Tab A" + unlocked bootloader screen, never gets past that and reboots indefinitely.
I tried A, A/B and all sorts of things in TWRP like wiping, resizing and whatnot.
What could be the cause?
Thanks in advance.
Tried downgrading to stock Android 9.0 and flashed everything (BL, AP, CP and CSC), let it boot, shut it down, then put TWRP with vbmeta on it and flashed the LOS GSI (A only) with it.
TWRP succeeded sucessfully, I reboot and it's stuck on the bootloader screen with the unlocked warning, reboots, gets a black screen, reboots, ...
I really have no idea.

hi friend, when we install a stock rom we need to activate developer mode and OEM unlock before making any changes, otherwise your device will be locked.i believe that's the case for you, try to reinstall the same stock system you put in before the lockdown, and about gsi, unfortunately i don't know any that work well.

Yes, I did that. I could install TWRP, but that's about it. No GSI will boot, it doesn't even reach the android boot screen, it just shows the bootloader unlock screen and reboots.

unfortunately GSI might even work at all, but the overall performance of the tablet won't allow it to be good, I remember testing some GSI when I had the tablet in my hands, nothing worked
