Data connection issue after fly mode - Xiaomi Mi Max Questions & Answers

I have this issue, both with xiaomi.eu and official global dev: after staying some minutes in fly mode, phone is unable to connect by data connection when I disable fly mode.
Someone has the same issue?
Thank you.

Yes, the same with my wife's phone (with 3/64 helium). The rom is from xiaomi.eu (2016.11.17,based on developer versions). The only solution is to avoid fly mode or reboot after

Sprint G2 Unable to use Wi-Fi and No Download Mode

Hello, I'm attempting to fix a G2 for a friend, which hasn't been able to connect to Wi-Fi, and in addition to said fix, they wanted CyanogenMod for the phone as well. I've had no such luck after a factory data reset, flashing the ZVG Stock ROM when Download Mode was available, and getting the phone to use apps such as GeeFree have been unsuccessful to flash TWRP. When I try to enter Download Mode now, the LG logo appears for a bit, but then shows the charging animation. Recovery mode is still available, and I can wipe the phone from there, but still no Download Mode. The phone currently can power on and function as normal, but Wi-Fi cannot be used, and there isn't any root access. Any help is appreciated!
UPDATE: I've successfully installed CyanogenMod, however I'm still not able to get Wi-Fi working at all. And the issue I had with Download Mode was that I used a bad cable. My apologies.

Stuck in the airplane mode after flashing custom ROM.

Hello everyone.
So I finally decided to reflash my Moto g5s (Montana), because an official stock ROM was driving me crazy because of its lags.
I have some experience with flashing. But never had a problem such as this.
I unlocked my Moto g5s.
I installed TWRP 3.2.3-0
I tried flashing my phone with:
LineageOS 14.1
Resurrection Remix
ViperOS
But decided to stay on ViperOS, as if it makes any difference because no matter what, I always had this problem after flashing with a custom ROM, my phone thinks it's in the airplane mode.
I even tried Android 8.1.0 Oreo - Stock Firmware.
Of course, I tried a factory reset and wiping everything that can be wiped.
I tried reflashing the same ROM several times, after flashing GApps, every time after an install wiping all the stuff via TWRP.
I tried reflashing TWRP.
I tried all the "simple" solutions there are, such as "turn on airplane mode and restart your phone, then turn it off".
But after every restart, when I long press power button, below options "Power off", "Restart", I see "Airplane mode is ON", even though it's turned off in the quick drop-down menu section.
I tried *#*#4636#*#* - Cellular Radio Power is always off and if I try to turn it on, nothing happens really, and after some time it switches off again by itself.
*#06# - Shows all my IMEIs are in place.
And still, when I try to dial a number, I have this message "Turn off airplane mode to make a call".
The only solution I've found but never tried yet is shown here (YouTube), but I need a ROM where my SIMs would work, which I don't have, obviously.
I reached the point where I would try anything only to get rid of this problem. And after many hours of trying decided to ask for your help, because I can't resolve it on my own.
Thank you in advance.
I tried flashing Montana-xt1793_nougat && oreo_stok-rom TWRP flashable, and that, from the look of it, resolved my problem.

Phone continue Rebooting

I've bought this phone only few days ago. Connected to wifi I started to install the updates included the OTA of Android Pie. After doing that my phone started to show a important wifi error. It could connect to my hotspot wifi (made with my second phone) but not to home wifi and work wifi. After trying to reset wifi settings, wipe data,... I decided to try to go back to Oreo using MIflashtool and the last Android One Rom available on miui english site.
I unlocked bootloader and put the phone in edl mode. I flashed the rom with clear all option active.
Now the phone, if it is tried to be power on, show the "Android One" logo and then it loop reboot.
I can go to fastboot, edl, can install twrp etc...
What should I do?
Really Thanks

Thanks for the help. Probably Xiaomi did something "wrong" with the Android Pie Update. I had to wait till the fastboot .tgz file of Android Pie and flash it trough Miflash. Now it rebooted correctly.
Thanks anyway for your help

Question Bootloader locked + can't access wifi

So I got this phone with a miui 12.5, it freezes all the time and I can't connect wifi, it just crashes when I try to. I tought of flashing a miui 11 ROM on it but I can't do it since my bootloader is locked, and I can't use miflash because I can't access the internet from the phone to put any kind of account on it. what options do I have? Is this phone lost forever? Thanks in advance.
I'm not sure, but possibly flashing in BROM could work.
However I was unaware this phone has a MIUI 11 firmware.

What am I doing wrong?

I have a Redmi Note 8T (willow) - unlocked - TWRP installed - rooted with Magisk 25.2. When I try to flash a custom ROM, all seems to go well. However, after reboot, the telephone reboots in TWRP, and keeps rebooting in TWRP. The only possibility left open to me, appeared booting in Fastboot mode and flash the stock-ROM with MiFlash.
This happened on a few occasions. Yesterday, I tried https://private.projectelixiros.com...2_ginkgo-13.0-20221025-1529-BETA-OFFICIAL.zip with the same result. Sofar I've only been able to successfully flash lineage-18.1-20221024-nightly-ginkgo-signed.zip, using the associated recovery, (But with that ROM, the phone-function didnt work with an MMI-code error.) So, at present, I'm again on stockROM, bootloader locked again - unrooted - back to day zero...

You must have the firmware requested by the OP, flashed it if necessary.
See this rom below where everything is explained.

Regrettably, my telephone is now hard-bricked. Recovery and Fastboot modes also not possible, so back to stock-ROM is no longer possible either. Only a flashing screen, and - when trying to enter fastboot mode, only short showings of the word fastboot, but no response in MiFlash. I think that a new phone is unavoidable.
Meanwhile, I've tried to enter EDL mode. Troed various fastboot commands, but no response from the telefone. Ultimately, I've tried to open the backcover (in order to reach the so-called "test points"), but that's easier said than done.
Website
is pretty clear, I know where to find those test points, but I'm lacking a 'heat gun', demonstarted in the youtube film. I tried it with a hairdryer, but that proved ineffective, moreover, the hairdryer stopped working (overheating?). Still need to check a possible fuse in the hardryer. Anyway, I'm awaiting a Redmi Note 11...

But what went wrong in the first place?
The flashing instructions quoted
Flashing Instructions
Clean flash (coming from a different ROM):
• Flash recovery (links above)
• Download ROM from the link above
• Download Magisk v23.0 or newer (optionally)
• Reboot to recovery
• Format data (if encrypted)
• Wipe system, vendor, cache, dalvik, data
• Flash latest android 11 global stable firmware (link above)
• Flash ROM zip
• Reboot and voila!
It mentions "flash recovery". The only method to install TWRP that I know, is through fastboot commands (fastboot flash recovery twrp.img, after having renamed the latest twrp image file), and then "fastboot reboot" while keeping Power + Volume Up pressed.
Prior to this, I had placed the firmware-, ROM- and Magisk-files on the phone.
After installing TWRP and Magisk, I wiped cache and Dalvik.
Then, when tried to flash the ROM, apparently that was wiped too. I think that it would have been better to reboot the phone after installation of TWRP and Magisk, then transfer the firmware and rom-files to the phone, and then boot into recovery again.
Anyway, that was not what I did...
Right after installation of TWRP and Magisk, having seen that the files to be flashed, were no longer there, I tried to install the firmware- and ROM-files with 'adb sideload' commands from TWRP. The flashing process seemd to go well, but booting to system proved disastrous...
A 'lesson learned' - at least for me: do not proceed if you - for some reason - can't follow the instructions. but break off, so that you can still reflash the stock-rom!
Sometimes, flashing the firmware with the Twrp does not work and you have to flash the complete rom with Miflash.
For EDL mode you will not have the necessary authorization.
See my PM.

what brick your phone is relocking the bootloader
never do that on a redmi note 8 !
I certainly did not relock the bootloader. After re-installing stock-ROM, unlocking the bootloader was always the first action before doing anything else...

Redmi note 8t(Willow).
Anyway, even if you had done it, it wouldn't have changed anything,except that you would have relocked the bootloader, since this model is intended for the global market with roms, Global, EEA, Russian, no CN roms.
Situation at present (4-11-2022): I have succeeded in opening the telephone in order to make the 'test points' approachable and to disconnect the battery. In the 'device manager', I've seen 'Qualcom' appearing on one of the com-ports. To continue, I now have to await a 24 hours break after too many times of opening my Mi-account during earlier attempts of flashing with the MiFlash tool .
.....
Well, 24 hours later, I've come to the conclusion that my brick definitively remains a brick. Tried again and again, but each time received an error "Cannot receive hello packet. MiFlash is trying to reset status.". And that's it...
Meanwhile, I had the impression that I might have better results with the Qualcomm tool QPST. The telephone - in EDL mode - was observed in QPST Configuration all right, but the flashing with QFIL failed with a consistent error: Unable to read packet header.
I've seen many reported occurrences of this error in various XDA fora, but nowhere a conclusive remedy. I'm out of options now...
Now, I get the information that the file that I want to flash, is too large. If only there could be a smaller file, only to restore the part of the os, through which to activate the fastboot and recoverymodes...
Well, after many tries, searching for solutions for the various Sahara fails that I encountered while using QFIL, I found a solution that really worked:
[GUIDE] How to unbrick RN8 (won't boot only backlight turns on for a second) using EDL
Hi all, after lots of trial & error, I would like to share how I managed to unbrick my Redmi Note 8 original thread: https://forum.xda-developers.com/t/need-redmi-note-8-firehose-without-authentication.4031513/ many thanks to dxD7 who provided...
forum.xda-developers.com
I could use the patched firehose file also on an older Global EEA version of the stock-ROM, and then everything worked fine... It took a while, updating the phone to the latest version, but that doesn't matter...
Well... the phone is working again with MIUI Global 12.5.5.0 (RCXEUXM).
Working, but... both IMEI's are null, therefore SIM cards are no longer recognized, which means that I can't use the dial function and can't use a mobile network. WiFi is working.
Moreover, the bootloader is locked again, but I can't unlock it with MiFlash Unlock, because this procedure requires connection via a mobile network. And without an unlocked bootloader, any possibility to root the phone, flash a repaired qcn file (with proper IMEI's), try out custom ROMs or whatever, is blocked...
Any option left? (Fastboot and EDL mode still possible).
Meanwhile, problems are solved to some extent:
Phone is unlocked, stock ROM re-installed, IMEI's are again reading correctly. Only problem remaining: network is not detected, i.e. dial-phone and mobile data not possible. Probably hardware-problem. (Tried all options I could find, but 'no joy'.)
Meanwhile, I have installed an SD card, and that makes all the difference. Tried installing PixelOS and PixelExperience: both installations problemless. Off course, still without dial-phone and mobile data. But, good enough to be confident to install a custom-ROM on my wife's Redmi Note 8T.

How to unlock without connection via a moble network since your phone lost IMEI?
I read every word you typed, and feel the mood you was at,
But in the end, a sad story.
I did flash my phone before I understood every procedure and knew how to fix or recover from it.
luckily things work as I expected.
Thanks God.

Thank you for your sympathetic response.
My answer to your question: Indeed, I don't have connection via a mobile network, and can't use dial-phone, but WiFi is all right.
When I started, trying to flash a custom-ROM, I did so with my experience of some years ago with my former phone: a Google Nexus (maguro) from 2011. Things were so much easier then, no data-encryption or whatever. As said earlier, the turning point was when I placed a cheap 32GB SD-card in my Redmi Note 8T. Now I could place all the necessary files on that SD card, which made the flashing (with OrangeFox) much easier. So, I'm not sad... The moment, my phone got hard-bricked, I bought a new phone (Redmi Note 11) for daily use. And then started learning: how to open the phone, where to find the "test points", how to get the EDL mode working, how to restore stock-ROM via EDL mode, how to restore IMEI's etc. etc. I have learned a lot, and every step was a question of try - retry - retry differently - retry again etc. But the ultimate success (with the exception of the "no network" problem, for which I couldn't find a solution) is quite rewarding. Of course, it took quite some time, but time is no problem for me. I'm retired a long time ago (I'm almost 80), so "it keeps me off the streets"...
