What about the notorious GPS locking issue on the Bison. On stock, it can't keep lock using driving navigation. It will constantly change directions as you are driving because of the lock issues.. Does it experience the same issue on custom ROMs?
[General Topics] dav1129:
I no longer muck around with root and custom software. No time....

Now I have an Umidigi Bison (2020). I'm very happy with it.

However I purchased a wireless adapter from rcd330.com for connecting Android Auto. Unfortunately, it cannot make the required Bluetooth connection with my (2020) Bison. Though originally compatible with Apple Carplay only, the seller known to many as Ddren, did said that the device now also supported Android. In hindsight perhaps I should of been more specific. Because while the documentation says the device Android 9 or above, it goes on to say, some Android 11 or above.

So I'm guessing the (2020) Bison with Android 10 is one Android phone which needs Android 11 or above.

While I am often tempted and don't need much of a reason to buy a newer model, I'd like to investigate whether updating 2020 Bison to Android is possible and if so, how? As mentioned, no longer much interested in rooting or custom roms.

Anyone?

PS I should add that current and seemingly latest OTA update is shown in the attached image.

Is it possible to update Umidigi Bison 2020 with Android 11 and if so, how?
[General Topics] dav1129:
Oh yes! I only noticed this yesterday. Because since replacing the factory head unit in my VW with one which uses Android Auto, it's the first time I used Android for navigation.

I notice the maps giving ridiculous directions before eventually but too late in real time traffic, providing correct directions. Is this because of a issue with Bison specifically? If I need Android 11, maybe best buying a new Bison. Or is it an issue even with newer Bison models? Thank you
[General Topics] dav1129:
As mentioned earlier, it's been years since I mucked around with rooting and custom rooms. Not since Galaxy 4 I think. Anyhow any chance of a quick heads up on what might be involved to update 2020 Bison with Android 11 for 2021 Bison? I can't remember but suspect TWRP rooting and manual install might be necessary....

Edit: I see now that my signature shows what I was using when last active here: Samsung Galaxy 4 Duos. OMG
[General Topics] kgoerbig:
I opened multiple tickets for the GPS issue with Banggood and Umidigi, only to have them closed. I did get some GPS stability by doing:

1.) ##8111## gets you to the factory test tool. Wireless > GPS Test

Offers multiple tools to reset agps, clear settings, and calibrate.

2.) Google Maps Offline. Downloading my state's map to my local storage improved accuracy greatly.
[General Topics] dav1129:
Read this earlier and tried it. Always got an error. However there's the app called Factory test does the same thing. Surprised you don't have the app? A lot makes no sense to e however did try AGPS restart. Did the same with the app GPS Test. Makes no difference.

I'll try navigating the same route as I did yesterday and was all over the place.

Otherwise it's upgrading to a new Bison. Probably the Bison 2 Pro but possibly, the GT2 Pro 5G. WiFi 6 which I already have at home and 5G when we get it. I just hope this Bison longer has the same GPS issue
[General Topics] kgoerbig:
Did you try downloading Google Offline Maps?
[General Topics] dav1129:
I didn't but I don't see how that would help? That increases processing map data. But seems to me the problem is when knowing where the car is in real time and in relation to the maps, And therein lies the issue at least for me, when the phone randomly loses the GPS signal, provides an inaccurate position and takes too long to establish an accurate fix.

In any case, eBay has had some awesome EOFY discounts in Australia so I bought a Bison GT2 Pro 5G.

I only hope it doesn't have it's own issues as I have since read a lot of one star buyer reviews on AliExpress complaining about some advertised apps not working and causing issues. The main complaint, which didn't catch me out though, is that buyers felt deceived when realised the OS version was Android 11, not the advertised Android 12. If they had followed the asterisk to read the fine print, those disgruntled buyers would have noticed that Android 12 updates are to follow by OTA. Somewhat deceptive I must admit. Check out the screenshots.
[General Topics] dav1129:
I have since downloaded the Google maps for my city and on shorted local trips, this 2020 Bison hasn't suddenly lost it's location or then had to scramble to provide new non sensical directions. I haven't tested the routes where I observed this behaviour before.

I thought this was all about a GPS hardware issue when the Bison had trouble fixing and holding a GPS signal? But if offline maps makes the difference then surely that points to a computing issue where the phone can't download and process online maps fast enough....

Anyway, I'll see soon if navigation using offline maps produces the same odd behaviour as I saw before downloading the maps.
[General Topics] kgoerbig:
It has improved after downloading offline maps, but I still notice glitches driving in city areas, and sometimes going around a curve that switches the direction you are driving, gps will sometimes flipout. It's definatly not perfect, and at this point I do not have a ton of options with this phone besides selling it, and getting something different.

Looking to get a rugged device like Umidgi Bison 2 Pro with a Helio P90 chipset. Anyone using this device yet?
[General Topics] kgoerbig:
Did you end up getting the Bison GT2 Pro 5G? If so, any GPS, or other general bugs?
[General Topics] dav1129:
Yes I purchased it for my partner and the Bison GT2 5G Pro for myself. And handed down my original 2020 Bison to my partner's son because of the GPS issues I had with it and incompatibility with Android Auto because it was Android 10.

I like both the newer Bison models. Both are now Android 12. The main annoyance with both are frequent alerts or notifications for something called Duraspeed whether enabled or disabled and frequent notifications that Quickstep has stopped working with the options to wait or close the app. And that is regardless whether using another Home app such as Nova Launcher or not.

Would love a heads up for either issue. Otherwise love both new bisons
[General Topics] beachbouy:
I have the GT5G as well now. Does anyone know what format I can do on the external sd card other than Fat32? exFat doesn't work and if I format in the Bison it defaults to fat32 - which is a terrible format for a large card, especially if you're going to have large files on it. I tried NTFS (a long shot I know) but no luck.

After a number of hours searching google, I found a single site that states the required format as vfat. That is a fancy term for fat16 and fat32. exFAT is not compatible and no other modern format is either. I would have thought a linux format (ex2,3 or 4) might be, but can't find any info. Seems a bit primitive unfortunately. I'll have to test OTG and see what it can read.
[General Topics] beachbouy:
Magisk is a good way to go now. I tried using the SP Tool to transfer a patched boot.img ((which it did) but GT2 5G was too smart and wouldn't boot because the partition was checked and failed verification. There is a "how to" I found for the previous bison that uses fastboot to transfer the patched boot.img and you need to add some extra lines to override boot verity. It didn't work for my GT2, but it probably would for the earlier one.

If you try to flash the file misc.bin your device can be in bootloop forever, please follow this guide to fix it.

It works with:

-

Xiaomi Redmi 10X 4G

-

Xiaomi Redmi Note 9

Method 1:

Once your device is on the black screen, plug it on USB (try USB3.0 first).

And then check if it is detected in adb recovery mode:

adb devices

If you can see your device in adb recovery mode, you have to erase misc partition:

dd if=/dev/zero of=/dev/block/mmcblk0p2

After it is done, you can reboot your device to system or fastboot again.

Keep atention, if you execute this command wrong, you will ERASE any other partition and it can brick your device forever and cause more damages.

Method 2:

Once your device is on the black screen, plug it on USB (try USB3.0 first).

And then check if it is detected in adb recovery mode:

adb devices

And then reboot to bootloader:

adb reboot bootloader

And then check if it is detected in fastboot mode:

fastboot devices

If you can see your device in fastboot mode, you have to erase misc partition:

fastboot erase misc

Keep attention, if you try to format misc partition, you will get this error:

Formatting is not supported for file system with type 'raw data'.

After it is done, you can reboot your device to system or fastboot again.

Keep atention, if you execute this command wrong, you will ERASE any other partition and it can brick your device forever and cause more damages.

Good luck !

I wanted to, but since I cannot even reboot it in fastboot mode, nothing detects the phone, neither ADB, nor Mi Flash Tool, nor SP Flash Tool...

The only thing I can do at the moment is to wait for the phone to exhaust its battery while rebooting over and over again, hopefully at that point I will be able to at least boot it in fastboot mode, but it may take some time considering the long battery life of the phone, so I wanted to see whether there was something else that I could try.

I know it is the misc.bin file that is messing everything up, the first time around I just loaded the twrp image without it and it simply didn't work, then I tried again with a different tutorial that I found, that that bricked it...
[Redmi 10X / 10X Pro Guides, News, & Discussion] VD171:

Just try.

Good luck.
[Redmi 10X / 10X Pro Guides, News, & Discussion] Dan984:
I tried, but with no success.

I finally found a way to turn the phone off (by pressing volume up + volume down + power button all together when the REDMI logo appears, and then releasing only volume up and down once the logo disappear, the phone reboots one final time and then it finally goes off), but the moment it gets connected to a power source it starts rebooting continuously again.

So I tried that procedure once again after I prepped SP Flash Tool, and at that point it does detect the phone but in EDL mode (I get the STATUS_SEC_AUTH_FILE error). I tried to bypass the authorization step as you detailed in another post, but unfortunately since the phone gets into EDL mode for not even a second, the filter wizard does not have enough time to do the installation.

I read online that there is a physical way to access the EDL mode, which require opening up the phone and kinda short circuit some point, but I am no expert on that matter, plus I cannot open up the phone without the proper tools... So, in conclusion, I think I need to bring it to a tech repair shop.

Nothing physical is broken or burnt, so I wanna believe that it is still salvageable... 🤞
