[Android Q&A, Help & Troubleshooting] tbart:
Fixed it myself!

Download & compile heimdall2 from https://git.sr.ht/~grimler/Heimdall (I'm on Linux).

Get official firmware. Unzip, untar, unlz4 (gosh, that's a lot of unnecessary compression).

Flash like this (for an A41, that is, double check your partitions are named like this!):

~/heimdall2/bin/heimdall flash \
--super super.img \
--bootloader preloader.img \
--uh uh.bin \
--lk lk-verified.img \
--up_param up_param.bin \
--efuse efuse.img \
--boot boot.img \
--recovery recovery.img \
--vbmeta_samsung vbmeta_samsung.img \
--md1img md1img.img \
--cache cache.img \
--prism prism.img \
--optics optics.img \
--vbmeta vbmeta.img \
--gz1 gz-verified.img \
--dtbo dtbo.img \
--spmfw spmfw-verified.img \
--scp1 scp-verified.img \
--sspm_1 sspm-verified.img \
--tee1 tee-verified.img \
--userdata userdata.img \
--md_udc md_udc.img \
--omr omr.img \
--param param.bin \
--verbose

Regardless of which USB (2/3) port or cable I use, I have to start heimdall within a second after pushing the volume down button to actually start download mode. I don't know if this is by design. Otherwise I only get

ERROR: Protocol initialisation failed!

or other (timeout) errors (-7).

Additionally, I can only issue one single command. Even using

--resume

does not work after the first command.

Heimdall 1.4.2 ran into timeouts in larger uploads (super.img) or the phone saying only official binaries are allowed.

Hope this helps someone. Took me hours to find out.

[Touch CDMA Accessories] fuller45:
well i just bought an 8gb micro SD for 30 bucks and im gonna put a bunch of music on my phone and make it my new MP3 player.

does anyone suggest any mini USB to 2.55 headphone jack product?

i found... http://www.tiltdepot.com/smartphone-experts-mini-usb-stereo-adapter/12A45A2373.htm

it's 5 bucks so not a cost really but just want to make sure that it'll work before i actually do buy it since it says works with the Tilt but i presume the 11pin to 2.55 jack is universal for most of these phones especially my Vogue...

PS. i have an FM transmitter from my mp3 player but it plugs into a standard sized headphone jack on the mp3 player, does anyone think it'd be possible to get a MINI usb adapter to a standard sized headphone jack and plug that in and have it work like that?

if the transmitter wont work, does anyone know where i could find, if possible, an FM transmitter from my phone to my car stereo? (not an auxiliary plug, my radio doesnt have one)

anything is a plus, thanks guys :)
[Touch CDMA Accessories] boomerangfarm:
I picked one up somewhere (a thread over at PPC geeks had a pointer I think). It cost twice as much but it has a microphone inline and a regular size jack. I can use an FM transmitter or direct plug-in in a vehicle. When a call comes in, the music is stopped and the phone takes over. When the call is done the music starts. sweet like pie. The cord is long enough to clip the mic to my shirt and Voice Command works great with it too.
[Touch CDMA Accessories] boomerangfarm:
http://www.oriongadgets.com/product_info.php?products_id=2087

is the one. I guess the mini USB cable I use is what makes it long enough.

Hello!

I ask for help to return to the second version of the firmware. Now stands the extreme version of the firmware India(M315FXXU2ATI4)B . I want to go back to my native Russia firmware(M315FXXU2ATC5) . The problem is that India's firmware one UI 2.1. And my native firmware on ONE UI 1.0 (if I'm not mistaken). When trying to sew native Russian firmware, gives out:

Rev.check fail. Device: 2. Binary:1

If anyone knows how to get me back to my native Russian firmware, please help.

[General Questions and Answers] chetanbhai:
Hi All,

I'm in a terrible situation right now :confused:. i have AQUOS PHONE Xx SoftBank 203SH phone with Build S0026, Its a Japanese phone which I had rooted via Kingroot yesterday and uninstalled few System pre-installed Apps. rebooted the device and now it's stuck on the SOFTBANK logo. I tried Volume Up + Power on but nothing happens, tried Volume down + PowerOn which also failed to go in recovery mode. now the phone is not even turning on however while plugged in the charging cable and turn on the power button it shows failed to read the MicroSD card. Looks like I need stock ROM for this particular model so I could transfer to the MicroSD card and try again.

or if anybody knows any other workaround or any trick to bring back this phone live.

please send me a link if any of you have a stock ROM or custom ROM I want to try and fix this phone.

[Xiaomi Poco X3 NFC Questions & Answers] YukarinVal:
So after fully setting up with all my apps, I find that the swiping is a bit crappy. The nav gestures doesn't seem to be that responsive. Even when typing using Fleksy, swiping to space works 7 times out of 10.

Does anybody else have this experience? Should I just rip off the screen protector?
[Xiaomi Poco X3 NFC Questions & Answers] H4R0X:
touch / swiping works fine, no issues here
[Xiaomi Poco X3 NFC Questions & Answers] Yepi69:
The screen protector is fine, among the best I've ever seen and I'm thankful for buying a phone that doesn't make me rush to buy a tempered glass and a case.

The problem is that Xiaomi won't let you set the sensitivity of the nav gestures and they only work on the bottom part of the phone, so you can't swipe to back anywhere on the screen, only the lower parts. As to why they don't let us tweak that is beyond me.
[Xiaomi Poco X3 NFC Questions & Answers] YukarinVal:
Yeah, I've already reached out to the Fleksy devs and just have to play around with their sensitivity.

The other thing about nav gestures is I just have learned how sensitive (or not) the side gestures and bottom gesture area.

Would prefer if I can tweak the sides to be a bit more sensitive and the bottom less, but ehh have to live with it I guess.

And yeah, after how ever long it was since I posted this, have to agree that the screen protector is quite good.
[Xiaomi Poco X3 NFC Questions & Answers] robogo1982:
The quality of the screen protector itself is utter garbage, I agree. It's plasticky, picks up smudges and skin grease very easily up to the point it becomes difficult to use the phone in direct sunlight if the screen brightness isn't high enough.

But as for swiping... I haven't noticed too much, I find it even better and more responsive than my previous phone (Realme 6).
[Xiaomi Poco X3 NFC Questions & Answers] petertakov:
Does a bare screen without any protector feel/look better in any significant way?
[Xiaomi Poco X3 NFC Questions & Answers] Nazri786:
Without the protector the screen feel sticky... Not a smooth swipe especially when your finger a bit wet...

Hi, I just read some info about 2 new Diamons for CDMA - first is very, very bad, IMHO has nothing similiar with Diamond (MSM 7500 400MHz, 128MB RAM...), but the second, HTC Victor will have same HW as Diamond, exept 256 MB RAM and 1340mAh battery. So, yes, it wil be thicker, due to batterry, and will least more, but as we know same option will come for us (1340 mAh battery, for the price of thicker phone) but I am not happy for RAM size.

[Xiaomi Redmi 4X Questions & Answers] jdr_85:
Hi,

I do not get VoLTE working on my Redmi 4X (last official ROM MIUI Global 11.0.2 Stable NAMMIXM). I tried with two SIM cards (1x Telekom Prepaid, 1x Klarmobil Telekom). Both of them support VoLTE and VoWifi in my father's Redmi 6A, so my 4X is the culprit.

I entered this *#*#VOLTE#*#* code which disabled carrier check and enabled VoLTE in the menu (see screenshot). But whenever I start a call, the phone switches to 2G or 3G.

Should VoLTE work in the 4X or not? I read some information, that Xiaomi morons broke this functionality with an update and never repaired it, but don't know whether this is true.

Method 1

In TWRP go to wipe

Swipe right for factory reset

Method 2

1. Connect phone cord to PC

2. Reboot into download mode (Hold down all 3 keys

When the phone reboot release power key and plug in to computer at the same time

It may take a few times to get the timing right)

3. Flash each part of the firmware into its slot.

BL_20xxxxxxx.tar.md5 goes into the BL slot

AP_20xxxxxxx.tar.md5 goes into the AP slot

CP_20xxxxxxx.tar.md5 goes into the CP slot

CSC_xxxxxx.tar.md5 goes into the CSC slot

4. You might do a Factory data reset if you use HOME_CSC_xxxxxx.tar.md5 in the CSC slot

5. Wait for the restart

6. Skip through a minimal setup

7. Activate developer mode

8. Allow usb debugging

9. Reboot into download mode

10. Flash recovery.tar in the AP slot

11. Reboot the A20 into TWRP and mount everything that you can.

12. Format Data (not just wipe) - don't restart

13. Flash Disable_Dm-Verity_ForceEncrypt

14. Wipe both caches then go back and Reboot into Recovery.

15. Restore your data backup.

16. Reboot
