[Tilt, TyTN II, MDA Vario III General] patrick2525:
I realize topic has been mentioned several times previously, but I think I'm missing something and haven't been able to find the answer yet.

T-mobile's 3G runs on 1700/2100 (per the Tmobile website).

The TyTn II can work on 850/1900/2100 frequencies.

(The Tmobile G1 works on 1700/2100)

I've seen several threads here about trying to mod the TyTn (via hardware/software/rom upgrades) to work on 1700, but I'm missing the purpose if it can connect to Tmobile's 3G on the 2100 frequency.

So does the TyTn need to connect on *both* the 1700 and 2100 fequencies to connect to the 3G network?? Or does Tmobile use the 1700 in some markets while using 2100 in other markets?

Thanks for shedding some light!

(I'm using TyTn II purchased in Asia (unlocked) with Tmob's flexpay with unlimited internet, here in metro DC area)
[Tilt, TyTN II, MDA Vario III General] maxh:
It won't ever work. Sorry. You have to connect to both: 2100 to transmit and 1700 to receive. Also, tmobile's 2100 is different than everyone else's 2100 so you're screwed both ways.
[Tilt, TyTN II, MDA Vario III General] iloveheat:
Tytn II (tilt keyboard)

same problem here. I cannot believe it. how is that this 3G is different everywhere you go? on the box of this phone it says that he has basically all all the different bands you need. and still it doesn't work? i have not tried yet to go downtown Atlanta, since i am not sure here in alpharetta the signal is deployed for sure. nobody knows anything at Tmobile. please let me know if you have any additional news about it, otherwise this phone is going on sale on ebay. period. thanx, Paul.
[OnePlus 9RT] Skywrath0135:
Copied from the OnePlus forums - no response yet so far :(

I recently got my new OnePlus 9rt, however I've ran into a few perplexing issues with the handset.

The first issue is that it is just outright missing the manual update option. No cog, no nothing.

The second issue which compounds to the first, is that every time I try to update the software to MT2111_11.A.07_2022031423170148, it fails. My current version is 11.3 according to the phone. Manually updating through the oxygen OS installer also fails. Which brings me to the next point..

The third issue is that under the model section of the phone, instead of saying the model of the handset, it says the model is Lahaina for arm64, which I'm quite sure it's not meant to be there. Everything else, build number, baseband version, kernel version (provided below) match the other handsets. However a cursory examination on this forum says that there were/are people on this forum with a similar issue to the second point.

So I'm wondering, is this ROM official? Or did I get a corrupted pre-install of the software on the phone? Or am I overthinking this?

Also messages don't delete completely in messenger app. You delete them, and then a second later they return.

For reference, here is the information..

Build number: MT2111_11_A.03

Baseband version: Q_V1_P14,Q_V1_P14

Kernel version: 5.4.96-qgki-g449ba87830ff

Thanks in advance
[OnePlus 9RT] bonez56:
Where did you buy the phone from and what country are you in? Currently the handset is only officially sold in China and India.

Was the package completely sealed, or has it been opened? It sounds to me like you have been sold a handset from the Chinese market and it's had the unofficial Indian ROM flashed on it.

ie. this one https://xdaforums.com/t/fastboot-rom-unofficial-op9rt-oxygenos-a-04-a-07-for-mt2110-devices.4404719/
[OnePlus 9RT] Skywrath0135:
I bought the phone from Kogan, and I'm from Australia. This isn't the first time I bought a OnePlus from there, but this is my first time with these issues specifically.

As for the package, it was sealed yes. And yes, those issues are practically identical with a few asides - such as the cog button missing. Such as that one..

Device name in settings displayed incorrectly "Lahaina for amd64" instead of expected "MT2111".

Yeah, that's 100% what it is.

[Samsung Galaxy Note 10+ Questions & Answers] boudy21462:
Hello every body

I bought this used note 10+ 5G from Dubai in last September, It was N976N/DS dual sim and I was working good in both sim cards but software in the mobile was too old so I tried to get KOO firmware to get OTA updates.

Now my mobile became so weired,

1- It became single sim phone only "N976N"

2- It considers the phone outside korea and anything related to network it named "Roaming" which made the phone loses network frequently to connect to another available network. Some times the phone changes time to show me both Seoul local time and Cairo local time same as roaming.

3- Cannot disbale or enable VOLTE option.

4- When it loses network it show me "Limited Services only".

5- Signal strength is very poor compared to my old Note 9, many calls are poor.

Notice:

On the back of the phone, it's written that the model is "N975FD" note "N976N" but the two IMEI & S-N are the same in the back and inside the options menus.

I'm bored with this phone and I didn't any person can deal with this phone.

Thank you

LineageOS is a free, community built, aftermarket firmware distribution of Android 12, which is designed to increase performance and reliability over stock Android for your device.

LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. You will need to provide your own Google Applications package (gapps). LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

This is an unofficial LineageOS 19 build for the Xiaomi Mi Pad 4 (clover).

Known Issues

Please tell me

Instructions

Boot to TWRP recovery (Vol UP + Power)

Format Data (backup sdcard before format) if MIUI was previously installed

Flash ROM (lineage-*.zip)

Flash Gapps (MindTheGapps-12.1.0-arm64 is recommended)

Reboot

Enjoy!

NOTES

Safetynet can pass on this ROM (without magisk).

And note that the MiPad 4 only works properly with fastboot and adb with a real USB 2 connection. Even computers with USB 3 an 2 ports will usually fail so you need a really old machine with USB 2 only or an old USB 2 only HUB connected to a USB port on the computer.

Good Luck.

Hi guys,

I flashed the lastest rom a week ago and it seems to be working great so far.

The only question i have is related to the light next to the front facing camera. Sometimes it is on and sometimes it is flashing and I don't understand why.

To me it looks like an info-led related to that the camera is active, but i am not using it. I also haven't configured any face unlock(not sure that even exists).

Anyone know what this light is for? I put a tape over the camera for now :)

Hello, I've read this entire thread. But does anyone with Wifi only MiPad4 have feedback on standby battery use?

For example Mokee uses about 1.5% battery per day if the tablet is not used at all. Some MiPad4 roms can use ~18% per day if the tablet is not used at all. I can't remember the exact reason for this high battery standby use. It was along the lines of the WIfi only MiPad4, along with rom combination was constantly searching for the non-existent 4g radio chip, or something like that anyway.

Thanks in advance if anyone does have feedback on this....

On my Mi Pad 4 Wifi, I noticed :

- the vendor.netmgrd service restarts in a loop :

- Regular messages about the radio HAL not being found

For netmgrd, I edited /vendor/build.prop to set ro.vendor.use_data_netmgrd=false.

Maybe /vendor/bin/init.class_main.sh could set the property, or stop the service.

For the radio, I edited /vendor/etc/vintf/manifest.xml to remove the android.hardware.radio and android.hardware.radio.config sections.

I don't know how it could be done in the ROM, unless doing a bind mount to override the manifest depending on the model.

I also see :

For the 7 APKs which are masked when the RIL is disabled, 5 have an incorrect path (it probably changed on an Android update), and the 2 which are correct fail due to SELinux.

Hi, I found a bug, when I turned on encryption it reboots (that's normal), but then it keeps rebooting and then I have to flash everything again.

I was not the first, so I hope it can be fixed soon , for the rest it looks like a awsome rom :-)

Hello,

I flashed this LOS19.1 ROM yesterday evening.

All is fine till now, but remains one strange thing.

Wifi bandwidth is very low on my fixed internet connection (ftth).

Is anyone having the same issue ?
[Xiaomi Mi Pad 4 ROMs, Kernels, Recoveries, & Other] ChicoDeGoma:
I'm having this very same issue, from EU too, I'm completely unable to add 5Ghz network via RQ and it won't show up in listed networks. Someone could give us a hand, please? Just fresh installed with TWRP.

EDIT: Okay so after messing around and searching around it seems like MiPad 4 doesn't exactly like all wifi 5Ghz channels and people suggest to lower your router wifi channels to 30/50/70. . .I fixed it especifying my country on my wifi settings (I have a Mikrotik AP) and that seems like it did the trick and it could see and connect to my 5Ghz wifi.
[Xiaomi Mi Pad 4 ROMs, Kernels, Recoveries, & Other] notsyncing:
For anyone who stuck in bootloop when enabling encryption: go to recovery, mount /data and remove this file: /data/misc/vold/convert_fde

Then reboot will be fine. No need to wipe data.
[Xiaomi Mi Pad 4 ROMs, Kernels, Recoveries, & Other] CityKev:
I've just bought this device and ended up with it booting into the China ROM in Chinese. I could connect to WiFi but couldn't get any further but I could still get into TWRP so I downloaded this ROM to an SD card on my phone and then put it in the Mi Pad 4 and flashed it.

It boots up and I can use the browser but several functions such as download manager keep crashing and I get an error message saying android.media.provider keeps stopping. At least I have a semi working device in English now but are there any pointers for what I should do next?

Thanks in advance 😉

Edit: I had done Wipe / Factory Reset / Format Data before flashing the ROM but I didn't reboot after formatting data before flashing. I didn't install MindtheGApps.

Further edit: In desperation I did format data and rebooted and it's working.

Thanks to the developer 👍🏻

Hi, I have a new, more serious issue. I had TWRP yesterday but now I have Lineage recovery. I'm trying to reinstall TWRP using ADB but although it recognises my device when I enter fastboot mode and out in fastboot flash recovery {package name} I get the waiting for device message.

Can anyone advise how I can get round this issue?

Thanks

Edit: I think this might be a driver issue in SDK Tools so I will try that first
[Xiaomi Mi Pad 4 ROMs, Kernels, Recoveries, & Other] GregEden:
To stop Lineage overwriting TWRP you will find as part of the set up there is a screen with a box to select or deselect installing Lineage Recovery. So when you get back to that point be aware and careful that it is not selected.

Secondly I have always found ADB on a MiPad4 always works better through a USB2 connection. If you have an old USB2 hub you can run it through that. USB3 is very hit and miss.
[Xiaomi Mi Pad 4 ROMs, Kernels, Recoveries, & Other] CityKev:
Thanks for the advice.

I realised that it was because I'd ticked the box ☹️ Is there any way in settings to untick it as I can't find anything.

I am using a USB2 connection but I'm pretty certain the problem is within SDK as it shows that Universal ADB Driver is in the wrong code but I haven't been able to resolve it.

One more question, I will have an OTG cable in the next few days so will that give me any install options with Lineage recovery?

Thanks in advance
[Xiaomi Mi Pad 4 ROMs, Kernels, Recoveries, & Other] GregEden:
I have stopped using this ROM, but I seem to remember it is part of the process when you first start the ROM
[Xiaomi Mi Pad 4 ROMs, Kernels, Recoveries, & Other] GregEden:
I use Linux and all the Android SDK is available in the repositories and specific USB drivers are not needed. An OTG cable will not help with that.

Have you tried just using a different cable?

Fastboot Install Method (No Root Required):

You will need the platform-tools from the Android SDK on your computer. Download the platform-tools as per your operating system.

Windows users will need proper drivers installed on their computer. You can try the simple FWUL adb/fastboot ISO or the Naked ADB drivers or the Universal ADB drivers if you don't already have a working driver installed

On your device, go into Settings -> About and find the Build Number and tap on it 7 times to enable developer settings. Press back and go into Developer Options and enable USB debugging. From your computer, open a command prompt and type:

adb reboot bootloader

You should now be in fastboot mode.

Download the correct image file and copy the file into the same folder as your platform-tools. Rename the image to twrp.img and type:

fastboot flash recovery twrp.img

fastboot reboot

Thanks for taking the time to respond plus all the other info below - it is much appreciated.

If I get TWRP back I assume a factory reset and start the set up again is the best option.

I've used two supplied cables from this device and my Redmi Note 10 Pro with the same result so I don't think that is the issue. I'm certain I've not got the right drivers installed in the right place so I'll try the options below.

As a final option I will ask my son to help. He's a software engineer with personal projects on GitHub but at no point has he ever offered to help. He'll have Linux so I can try that route.

Thanks again.

On a general note, it's strange that Lineage has such a limited recovery and it isn't the slightest bit intuitive or very functional. A choice between that or TWRP when installing would be great.
[Xiaomi Mi Pad 4 ROMs, Kernels, Recoveries, & Other] CityKev:
Latest issue:

I installed the MindtheGApps package using Lineage recovery but when I open Play Store I get a message that my device is offline but I'm connected to WiFi so it just hangs.

I've seen in the thread that it has been an issue for some but I can't see a fix for it.

I am still struggling to install TWRP and it's definitely an abd interface driver issue I think. I can input adb devices and my device is recognised but when I enter Fastboot mode and enter fastboot flash recovery [file name] I either get error 21 or sometimes Fastboot screen goes black and there is a message at the top saying press any key to power off.

I've tried installing Universal ADB Driver etc but nothing is working. If I can get TWRP back I would try another ROM but not while I only have Lineage recovery.
