What about the sound quality any improvement from the stock ROM cause my PUBG sound is bad on stock ROM
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] FloFloFlow:
Impossible to boot, stuck on logo. I followed exactly the instructions.
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] merser2005:
Try again with new firmwareQupdater
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] FloFloFlow:
Ok it boot with this new zip, thank you.

I will use the ROM few days and then give a feedback, but it seems fine so far !
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] saepurusass:
I gave it a try.

Well, it sure is different from what I am use to. But you can customise it.

It seems to be mostly working. No big errors found yet.

One problem.

When calling, microphone gain/volume is very low. It is difficult for others to hear what I am saying.

It is much better when I am in speaker mode. But that is not solution, it is bad workaround.

Not sure what the problem is.

Could be microphone low gain issue.

Could be that noise cancellation or something else is causing it.

Maybe automatic gain or something.

It is possible to record better audio as speaker mode works better. Not sure what it does differently.

Same problem with LineageOS. And I think ArrowOS had the same problem - but can't be 100% sure at the moment, I used it very shortly because bluetooth audio did not work there.

My old Umidigi One has MUCH better sound when calling. I do not want to make it very dramatic but it is very close to being like night and day. There is quite a big difference, much more than I would call normal.

I never even switched it on with stock rom, so I do not know how it performs in stock rom.

For now I can not use it daily as call quality is so poor and I need it as a phone.

I hope at some point it will get fixed if someone can understand the problem and how it works in android.

I tried to play with mixer xml files a bit but there are millions of setting and I did not really understood what was going on. I tried to change some settings that seemed like relevant, but no changes.

Audio settings should be simple but they are far from simple in android... at least not to me.

Problem on setting sound, cannot set ringtone and setting crash

Edit: only in no Gapps version
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] saepurusass:
I have also Vanilla version (no gapps).

I can set some ringtones (from pixel list some work). Others just start to show spinning loading ring or something like that and nothing happens.

Same for notification sounds. Some from Pixel list work, most do not.
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] czajunia:
Do we need to install this over Android 10 or can it be flashed on top of Android 9. Reason I am asking is that I flashed it over Stock 11.1.171 and I cannot connect to the WiFi to finish the setup on the first boot. Thanks.

EDIT: This also happens after installing a version with no Gapps. The WiFi just keeps dropping signal and reconnecting. Plus the mobile data doesn't work either. Similar thing happens and the phone keeps disconnecting from my network and trying to reconnect a moment later. Any ideas? Thank you.
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] czajunia:
Also after flashing this ROM I can no longer boot into the stock ROM after flashing with QFIL - I've tried a few times and it just gets stuck on either Lenovo logo or gets rebooted into the download mode (with the blue light on and nothing on screen). I suppose it might have something to do with Firmware Q Updater even though I thought that flashing with QFIL will overwrite this. When I re-flashed the ZEN OS it worked fine and I could boot to the system again, but I have no data connectivity so can't really use it.

Do you have any idea what's happening and what I am doing wrong? Thanks!
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] downforce25:
Hello,

I had the same problem. For data connectivity, just set manually APN network settings , save and reboot the phone. Set 4G network as favorite network. ZenX-OS is very promising, I'm testing it since yesterday ant it looks great. No major issue for the moment.

To use Z5s stock rom, maybe, you need to flash back to the original firmware to make it works.
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] czajunia:
Cheers. Yes, that's exactly what I did. I flashed L78071_CN_SECURE_USER_Q00024.0_P_ZUI_11.1.171_ST_191023_qpst using QFIL which went OK but I cannot boot to the system as I get stuck. I swapped the recovery IMG file in the unzipped folder so I can have working recovery after flashing and that works OK as well.

Did you have problems with WiFi as well or just cellular data?
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] downforce25:
Cellular data is working and wifi is OK too.

For wifi, I only had a small issue during the installation process. I've deleted the home network saved. Now wifi is working perfectly
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] czajunia:
What version of ZUI did you install this ROM on top of? Cheers.

#ZUI11_0_224Global
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] czajunia:
Thanks man. Will give it a go. Do you just copy system_1 to system_15 from Z6Lite to 171 and flash like that? Also, there is a link to MIUI12 in your post? Did you end up installing that as well?

EDIT: Ignore the question regarding the system files. It's quite obvious after downloading the Z6Lite zip.

EDIT1: Unfortunately this didn't work either. Still get stuck. I get to the Lenovo logo, it starts changing the colors as if it was booting correctly, then it stops for a moment and reboots to the blank screen with the blue LED on with nothing happening.
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] downforce25:
Yes, you just have to replace 15 system files. I didn't try MIUI 12. For the moment ZenX-OS seems to be stable and functional as I expect.
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] czajunia:
I have just installed ZENX again and booted without an issue (after re-flashing stock ROM several times with different options and always getting stuck on the boot). This is so weird.

Also, I removed the SIM card altogether to see if it affects the WiFi but unfortuntaly WiFi is still a no-go for me.
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] downforce25:
Delete all old wifi network saved. Reboot your phone. Reboot your box. Verify in your admin box page if there is a mac address filter. Enter your phone mac address manually. Try to connect to wifi network.
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] czajunia:
Thanks, will give it a go when I get back home. By rebooting the box I suppose you mean the WiFi router, don't you?

On a different note would you have any idea why I cannot boot to the stock ROM (after installing stock ROM that is) since flashing this one for the first time?
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] vesdan:
Im flashed this z5s_11.3.169_GLOBAL_ZaZzA from https://mega.nz/folder/PegDDQ7I#bmCCIt1lAWAe7ui_gkmwSQ/folder/GLJwyY6J and no problem with boot and wifi. Unzip and start 00flash all via fastboot
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] czajunia:
​

Unfortunately that didn't work either. I've tried two different WiFi networks with no luck. The settings are most likely correct as the phone connects to a WiFi stays connected for a few seconds, disconnects and the proces repeats.

And exactly the same thing happens with celular data. I've tried two different sim cards and also setting APN manually with a reboot. The phone just keeps connecting and disconnecting from mobile data.

---------- Post added at 11:50 PM ---------- Previous post was at 11:39 PM ----------

Cheers for that. The link takes me to a Pixel Experience folder/files. Is that correct? I'm on my mobile at the moment and haven't downloaded anything but just wanted to check if that was correct.

Also, my problem is that I cannot boot to anything I flash either with QFIL or recovery as my phone just gets stuck. The only ROM I can boot into currently is ZenX for whatever reason.
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] vesdan:
On Mega https://mega.nz/folder/PegDDQ7I#bmCCIt1lAWAe7ui_gkmwSQ is more folders, you can download everything. Im testing AEX, Pixel, ZenX, Havoc. Now i using Havoc 3.6 on Android 10 and is very very good ROM. Here is more ROMs with instruct how to install, so testing.... https://t.me/s/z5supdates

Only one time i have stuck boot, everything reboot to fastboot after install Havoc. Again im installed firmwareQupdate and perfect.
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] czajunia:
So this was a no-go for me either. After executing the first fastboot command I get a message:

target reported max download size of 805306368 bytes

Invalid sparse file format at header magic

And nothing happens afterwards - there are no other messages and the cmd gets stuck with a flashing underscore.

I managed to execute some other commands successfully but most of them (for example cmnlib64, cmnlib, tz) returned a following error message:

FAILED (remote: Flashing is not allowed for Critical Partitions)
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] vesdan:
This is OK, you must wait 5- 10 minutes, because fastboot cant send more that 750MB. Fastboot recompile image to 6x 750MB

Important is system, boot, vendor, vbmeta, dtbo

Just run the bat file and wait for reboot
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] czajunia:
Oh, thanks for that. I waited for probably 5 minutes several times and since nothing happened i just aborted the process. Will wait until it's finished then.

What about the other issue and the error message saying: "FAILED (remote: Flashing is not allowed for Critical Partitions)"? Would you know why I am getting this? Or do you think it will be fine even though I cannot flash most of other partitions? Cheers.
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] vesdan:
I have the same commands and all works perfect

meybe fastboot protect phone
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] czajunia:
OK, so I ran the script and waited until it finished. And it worked fine. As you said I needed to wait for longer. Flashed everything eventually apart from those protected partitions.

However it still hasn't solved my problem. After rebooting the phone got stuck on the Lenovo logo and rebooted itself into this Diagnostic mode with a blue LED on - exactly the same way as before when flashing wtih QFIL.

I'll try install ZenX again. Maybe flashing the modem partition using the script will fix my WiFi problems. Probably unlikely but since I've pretty much run out of ideas I might give it a go.
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] vesdan:

Notes: it is recommended to not flash FirmwareQUpdater over GSI vendor, it could hardbrick your phone into deep sleep EDL, so if you were on a GSI, flash first QFIL Rom again (in QFIL don't forget to disable the option, erase all before download)
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] czajunia:
I have red Lenovo logo that starts changing colors for a few seconds, then it gets stuck on the logo and reboots to the black screen with blue led.

I did instal the FirmwareQUpdater, however before flashing the ROM not afterwards since that was the way to install ZenX decribed in the first post. I though it should be the same when installing QFIL ROM.
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] czajunia:
EDIT: I managed to install the latest Havoc 3.7 and boot into it. However the WiFi and cellular data disconnection problem is exactly the same as with ZenX beforehand.

It's also quite weird that I can't boot into the stock ROM directly after flashing it either through QFIL or fastboot and at the same time have no issues booting into either ZenX or Havoc.

Many thanks for your help so far. Appreciate it.

[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] czajunia:
Thanks for the link. Do you think this will also fix the WiFi disconnection problem?

I will definitely give it a go. I just need to re-flash the ROM as I have tried to revert back to stock (unsuccessfully) again. I hope this will fix it but on the other hand I am not sure as I can actually see that VoLTE is enabled and active when the phone gets connected to the data services for a short while before it disconnects.
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] Awesome0123:
Hi, when I changed the battery temperature in the quick settings panel it keeps crashing the system UI. Therefore I needed to reinstall.
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] czajunia:
Unfortunately this doesn't fix the problem. The WiFi issue is exactly the same. On top of that after flashing the patch the mobile network stopped working altogether (I've tried both SIM card slots with a reboot). Running the uninstaller script gets me back to the square one. :(
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] downforce25:
Hello, try to install an original stock rom with QFIL. Juste for testing wifi and data networks. After that, install twrp official 3.4.0 , flash the dedicated firmware if it is necessary and flash a custom rom. Always wipe necessary files before, to go on a clean install.
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] czajunia:
That's the problem. Since flashing ZenX for the first time, I can no longer boot into a stock ROM. I've tried installig different versions using QFIL, MiFlasher and also the fastboot script we spoke about earlier in this thread. The ROM flashes OK, I can install custom recovery afterwards but the phone gets stuck on Lenovo logo and reboots into an empty screen with the blue LED on - exactly as described earlier.

I am trying to install MIUI now but I doubt it will make any difference. Since I've run out of ideas I thought I'd give it a go. anyway.

---------- Post added at 03:01 PM ---------- Previous post was at 02:38 PM ----------

I would imagine I need a script similar to the FirmwareQUpdater for the Android 9 even though I was under impression that flashing stock ROM through QFIL would overwrite everything. (confused)
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] czajunia:
As expected the MIUI was a no-go. either I managed to flash it following the procedure on telegram. However, I had to install an older MIUI version first and after installing the latest one in order to boot to the system I still had to flash FirmwareQupdater even though it wasn't mentioned in the procedure. Otherwise I would get stuck.

After that I tried manually flashing a modem file from a stock ROM (NON-HLOS.bin from 3 different ROMs) and that didn't work either. I still get the WiFi and mobile data reconnecting constantly.

Do you know if there is a way to completely wipe the phone and start 100% from the scratch including locking the bootloader etc?

EDIT: Also, could someone please explain what is the reason and what happens during the boot process if it stops on the Lenovo logo and reboots to the blank screen with the blue LED? Cheers.

EDIT: I just realized that it's not just cellular data that keeps disconnecting it's the mobile connection altogether. Bluetooth seems to be working fine and I even managed to use Bluetooth tethering from another phone.

Do you think it's possible that coincidentally my modem/radios broke roughly at the same time and that's the actual reason why they keep reconnecting? Or if they had been broken I wouldn't get any connection at all?
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] carlshark:
As previously recommended, do QFIL first. Relocking the bootloader probably won't help in figuring out whether this is a software or hardware issue. On stock ZUI it should have no problems ideally.

I figured this happened after you installed QFIL and custom recovery. I might be wrong. I encountered this before, I don't remember what I was doing wrong but it was during install of an Android 10 GSI. The recovery was not the official one yet. I had to reflash using QFIL to get back to a workable state, so I think it's either an incompatible recovery or an improper flash (no OS detected during boot).

Might be a modem issue, corrupted partition maybe? If it's hardware then yes, you might not have any connection at all; or if your MAC address or IMEI is all zero this no signal scenario can also happen.
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] czajunia:
Thanks for the suggestions.

Yes, of course, I get that. And that's what I did. I even tried flashing one of the early stock ROMs with MiFlash (there is one on 4pda.ru). The problem I have that I cannot boot to the stock ROM after flashing with QFIL which I do not understand.

I suppose flashing stock ROM with QFIL (given I can actually boot into the system) should fix the corrupted partition, shouldn't it? I just hope it's not a hardware issue.

So if I understand correctly if the boot process stops on the logo and reboots to the blank screen that essentially means there is no system installed, doesn't it?

[MENTION=2618657]czajunia[/MENTION]

I had the same issue (bootloop with blue led) when I tried to install ZenX-OS for the first time without flashing with FirwareQUpdater first. -> Back on Lenovo Stock rom with QFIL -> flash TWRP Official 3.4.0-0 -> wipe necessary files -> flash the new Rom.
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] czajunia:
Which stock ROM exactly did you flash with QFIL and which version of QFIL did you use? I have just flashed 10.5.205 using MiFlash (have some issues with the QFIL on the laptop I am currently using). The flash process was successful. However after rebooting I got stuck on the Lenovo logo and eventually rebooted to the blank screen with blue LED. Exactly the same problem I had after flashing stock 11.1.171 ROM using QFIL a couple of days ago.

Would that mean that there are some problems with the system partition? If that's the case why would the flashing process not return any errors?

Thanks.
[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] carlshark:
Try relocking the bootloader after QFIL. It might be that device encryption needs to be reinitialized. Since the bootloader has been unlocked, the device thinks that encryption is not needed and tries to start. It's just my theory though.

If QFIL goes through without any problems then probably your device storage has no problems. I don't remember exactly but I had one instance where I was only able to boot to 11.1 after relocking the bootloader. It won't be a problem to unlock again as long as you can get to the bootloader and use fastboot commands.

Data connection on dual sim.

I try to use two sims as one for call, the other for data.

I can send and receive call, but sim2 data is never acvated (i can see signal full, but no 4g or LTE mark on signal, APNs are set correcty.)

I switched sim slots, but same result.

if i only use one sim, call or data, i have no problem. (sim1 for call and data, sim 2 for only data sim, and both are ok when it is used only alone)

does this happen only to me? (i use gapps version, July 30, 2020 version)

As some others have written before, there seems to be a problem with WiFi.

For a while it works OK. But then all of the sudden WiFi starts to disconnect wait and re-connect very often. Sometimes it takes up to a minute to re-connect, making it very difficult and annoying to use and it can disconnect again in less than a minute.

It is not signal problem. It works just fine for about 10min +/- before it starts to misbehave. Every other device works just fine in the same spot.

I have version 1.7 20200730 installed.

[Lenovo Z5 Pro (No GT) Q&A, Guides, Development] saepurusass:
All GSI roms I have tried have problem with bluetooth audio. Pairing seems to work but nothing else.

I use bluetooth audio almost every day (motorcycle intercom), and I need it working. Missing bluetooth audio is a no-go for me. ZenX has no problems with that, bluetooth works well.

I do not need WiFi every day all day, so I can live with wonky WiFi for now.

I am using only wifi or only mobile data, the other one is disabled. When I am at home, I have wifi enabled / data disabled. When I am out, then the opposite, data enabled / wifi disabled. Data seems to work just fine. Only wifi has problems.

LineageOS has also some problems and is no-go at the moment. And it seems there is no development.

ZenX is so far the best non-gapps ROM I have tried. Sure it needs bit polishing, but for me it is quite usable as daily driver.
