[OnePlus Nord N200 5G] oCAPTCHA:
Something that is not well known, is that the OEM unlocking toggle is grayed out with that "OEM Unlocking - Connect to the internet or contact your carrier" message until you have allowed google play services to run with internet access. I suspect it submits and checks hardware ID's against a blacklist before Google sends a response whether to allow the device to allow OEM unlocking. For the unlocked version, this was all that was required. For the T-mobile / Metro versions, you have the extra SIM unlock software restriction steps afterwards.
[OnePlus Nord N200 5G] jilebi:
You are correct. That is not well known, that one needs internet access before it can be ungreyed. Thanks for sharing.
[OnePlus Nord N200 5G] yellowsnow4free:
Thanks @darkghost568 and @bouyakasha for your info in this thread!

After 5 months of waiting (1 month on Metro to start the process), I finally SIM unlocked both of my parents Metro N200s today. From a software standpoint, it sounds like I can "convert" these Metro phones to the OEM version (direct from OnePlus) and get OTAs, right? Is this the same as a bootloader unlock? I've done SIM unlocks and bootloader unlocks before, but the term "OEM unlock" is new to me.

Just want to confirm before I start looking into this.

Thanks!
[OnePlus Nord N200 5G] darkghost568:
Not quite. The legit OnePlus OEM can get OTA updates, but the converted models tend to fail some checks during the on-device upgrade process, especially when it comes to incremental OTA update packages (@ / AndyYan has talked about this a bit across other threads before). However, you can still install the full update packages manually via the steps in the OP, and for incremental updates, following my guide here. It's worked fine for me until the most recent 11.0.7.0 incremental OTA since that required recent versions of packages that contained breaking dependencies/version mismatches for the update_payload_extractor tool, which hasn't been updated, so ymmv
[OnePlus Nord N200 5G] yellowsnow4free:
Thanks for the prompt reply!

I'd really like OEM OTA updates, but since the phones are working OK for now perhaps I'll leave the phones as-is.

[Galaxy Tab 4 Android Development] Dvalin21:
Wonderful rom sir. My first issue is that Im not able to sign into playstore when or get past "Getting tablet ready" it always says "Couldnt connect" Not sure if its the rom or the gapps but im using opengapps. Anyway, thank you so much for the hard work that you have done with this rom. Extremely impressed. Thank you so much and looking forward to see more of your work.
[Galaxy Tab 4 Android Development] crazydrive22:
Are you sure Wifi is connected?

If yes, try a different package of Gapps or try to restore a older backup (/data only) from a different ROM, if you have. Also be aware, that our tablets cannot connect to Routers with WPA3.

This will be fixed in one of the next builds.
[Galaxy Tab 4 Android Development] Dvalin21:
I tested mindthegapps from this link https://www.cyanogenmods.org/downloads/mindthegapps-11-0-download/ its letting me setup, so it just opengapps that is the issue. Will share more later
[Galaxy Tab 4 Android Development] crazydrive22:
Aye. Sometimes the Setup Wizard is causing troubles.
[Galaxy Tab 4 Android Development] Dvalin21:
logcat and kernel logs. Also, the button for the camera is so low on the screen its cut off. I tried to make a phone call earlier, but it would just end the call immediately. Im able to get on the internet with 4G though
[Galaxy Tab 4 Android Development] crazydrive22:
Hi. I´ve tested the Issues you mentioned.

The Camera App seems to be broken or has a wrong resolution. That´s nothing i can fix but i´ll report it to the devs. As a workaround install Open Camera. This App is working normal.

I tested phonecalls (in and out) with 4G and Edge. Both are working for me.

Maybe there´s an issue with your local provider. If the problem persists, i would suggest to dl ROM and Gapps again (maybe a file is corrupted), delete your ROM in TWRP + format /data and do a clean install of both, ROM and Gapps. Often this will fix those errors.

Your logcat is looking not too bad except a crash of firebase, what definetly could cause the trouble. But we´ll see it, if you´ve done a clean and fresh installation.
[Galaxy Tab 4 Android Development] Utherbone:
Hi, I got the SM-T531 tablet and I'm going to download this ROM and see how it behaves I will do all the possible tests I can do, to contribute. There's no way the 3g works right, just connections right?
[Galaxy Tab 4 Android Development] crazydrive22:
Yes, unfortunately 3g isn't working at any ROM from 9 to 11.

[Galaxy Tab 4 Android Development] Utherbone:
Hi @crazydrive22 . I'll take the opportunity and ask you a question of mine. I'm having trouble flashing any SM-T531 compatible roms. I will list the steps I followed.

1 - Flasing twrp with heimdall. At first I tried here: https://twrp.me/samsung/samsunggalaxytab4101.html but ta off the link there.

I downloaded it here on the XDA forum: https://xdaforums.com/t/recovery-3-5-2_9-unified-matisse-millet-twrp-recovery.4019831/ ;

2 - full wipe and format;

3 - Flashing this rom (with or without gapps) Resulting: Loop in Samsung logo or should I wait too long?

Thanks for working.
[Galaxy Tab 4 Android Development] crazydrive22:
Hi.

First boot can take a lot of time. If it's not booting i would suggest to flash Stock 5.0.2 and start again from scratch. It's nescessary to had 5.0.2 installed once to make sure, that the Bootloader is updated. The Bootloader from KitKat (4.x) is not working with LineageOS 9 or newer and it's forks like crDroid or Cypher. The TWRP from Matteo is good, it's the lastest one and working well. But i can't tell you anything about Heimdall. I'm using Odin only to flash Stock or TWRP.
[Galaxy Tab 4 Android Development] Utherbone:
Thanks for the answer, it must be the 4.4.x bootloader, I didn't even ask if I had the 5.x.x one, I'm flashing the 5.0.2 About haimdall. It's wonderful, a point that can be negative is that the process is more manual, you must select each file for its respective partition, the good thing is that with it you can capture the pit file, it is very rare for an error to occur except if there is a problem on the PC or cable. It works on Linux and Windows and Mac OS X. I will return with news.
[Galaxy Tab 4 Android Development] ThetaProtocol:
This is working amazing on my SM-T530NU, far better than whatever Nook bloat that was running before.
[Galaxy Tab 4 Android Development] groulo:

I will continue using this rom, very happy with how it works.

I hope you continue with the updates. Great job

[Galaxy Tab 4 Android Development] chongtak:
Isn't there a way to change the charging animation when the device is turned off and charging? There is no percentage and zero clear way to know how much the battery is charged.
[Galaxy Tab 4 Android Development] crazydrive22:
An easy way is to use an App like True Amps to change the Animation. It's working without root.

Check out this Video.
[Galaxy Tab 4 Android Development] chongtak:
Thank you but I meant when the device is charging when turned off. Because the animation when it's turned off is a simple black and white animation with no percentage. There is no way to know whether the battery is at 20, 40, or 60%.
[Galaxy Tab 4 Android Development] crazydrive22:
Yes, you can change the Offline-Animation with this App. Unfortunately CipherOS is not providing any other Overlay for Offline-Charging. crDroid for example is doing this by default.

[Galaxy Tab 4 Android Development] groulo:
I have flashed Stock Lollipop through Odin and I have flashed twrp-3.6.0_9-0-matisse and CipherOS-1.7-ASTRA-20211213-1946-matisselte-UNOFFICIAL-VANILLA from scratch and the same thing happens.
[Galaxy Tab 4 Android Development] crazydrive22:
Re-download the files (TWRP + ROM), to make sure that they are not corrupted. You can also check with a lower Version of TWRP and/or a different ROM like LOS18, if the error is gone or not.

If not is the last thing i know the re-partition of your Tablet with a PIT-File via Odin.

If this also is not working, i could be a hw problem.
[Galaxy Tab 4 Android Development] crazydrive22:
Ah, I didn't think about Odin. Sometimes Odin is a *****. You can try a different Version to flash TWRP and/or a different Cable. I had this once and it took me two full days to find out. :D
[Galaxy Tab 4 Android Development] groulo:
I just restored a Crdroid backup and it works
[Galaxy Tab 4 Android Development] crazydrive22:
That's good, so the hw is fine.

After many tests and not making recovery start, I go back to CrDroid, which does work for me.

A shame since I really liked rom and it is very fluid.

[Galaxy Tab 4 Android Development] groulo:

[Galaxy Tab 4 Android Development] crazydrive22:
Ok, same as mine and here it's working well.

Try the following:

Got to TWRP and delete all partitions + format /data

Install CipherOS+Gapps+Root(if needed)

Start it once

If it's running go back to TWRP and restore /data only(!)
[Galaxy Tab 4 Android Development] groulo:
I have performed the indicated steps and I still can't restart in recovery
[Galaxy Tab 4 Android Development] crazydrive22:

Ok, i've started building matisselte. Did you dl from AFH or from Mega?

Maybe there's a problem with AFH atm.
[Galaxy Tab 4 Android Development] groulo:
I have tried it with both and I have installed lineage os and entered recovery. It only happens to me with this rom.
[Galaxy Tab 4 Android Development] crazydrive22:
OK, new build is up.

I've installed it clean with Open Gapps and Magisk. Booted well and is working normal. Booting to twrp is also working well.

Give it a try.

If it's not working, try to install ROM only, to sort out a problem with Gapps.
[Galaxy Tab 4 Android Development] groulo:
The same thing happens to me, the only thing that this time I have solved it by reinstalling TWRP from odin.
[Galaxy Tab 4 Android Development] Joschi 744:

[Galaxy Tab 4 Android Development] Utherbone:
[EDITED]

Hi. Your firmware stock is 5.0.2 ?

If it's 4.4.2 the rom won't go up, updates to 5.0.2 which will solve.

If you have any questions about how to proceed, ask, but they will be happy to help.

[Galaxy Tab 4 Android Development] crazydrive22:
With FW 4.x it would not boot at all.

Same happend to me and i don't know why. Best workaround is to make a backup of /data with Nandroid, do a clean flash of ROM, GAPPS, Magisk (if needed), boot once, return to TWRP and restore /data from your backup.

Thank you for posting the new build. Flashed fine. I like the Google startup. For a brief period of time, the tablet was identified as a Google Pixel 2. I'm always trying new things.
[Galaxy Tab 4 Android Development] SteinbeckFan:
Quite the opposite with build 20220412, Screen CAST WORKS! Android 11 for some reason broke screen casting with my Sony TV. CypherOS is the first Android 11 that has a working Screen Cast.

One odd behavior. Boot time is really long. It takes exactly 52 seconds from the time the Galaxy Tab 4 logo appears on power up until the Google logo appears.
[Galaxy Tab 4 Android Development] crazydrive22:
Good to know. I think it was fixed by LineageOS (where I grab some stuff) or @matteo0026.

In both cases it should also work in new Builds of crDroid 7 and LineageOS 18.1

I know about that long booting time. It's the same for all Tab4 Custom ROM. There's no fix so far.

Problems Problems Problems. First I tried an update "dirty" flash to the previous and working build. In doing so the Google Apps were completely gone. Then I tried a clean install and downloaded the latest Google nano-sized apps. Install goes fine but then tablet reboots into recovery after getting stuck at the Google startup logo screen.

Tried a third time using pico-sized Google apps. That seems to work but then get stuck at a setup screen called "Just a sec" after WiFi network setup. It never progresses past that.

I can do a working install without the Google apps. But I can't get a working tablet if I install the Google apps after installing the OS. Any ideas on what to try?
[Galaxy Tab 4 Android Development] crazydrive22:
That's interesting. I had no problems with dirty flash, but I dirty flashed ROM, Gapps and Magisk in a row. Try to restore your backup and do the same. Otherwise you could try FlameGapps instead of OpenGapps.
[Galaxy Tab 4 Android Development] SteinbeckFan:
I tried FlameGapps but it's only available in ARM64. It won't install. I also tried MindTheGapps but that won't install either. I get an error message "Could not mount /mnt/system! Aborting"
[Galaxy Tab 4 Android Development] crazydrive22:
Here, try one of them. And don't forget to format /data, before you start installing anything.

[Galaxy Tab 4 Android Development] SteinbeckFan:
I found one that WORKED! The file name is:

BiTGApps-arm-11.0.0-R45 (www.droidthunder.com).zip

It installs a very minimum Google App. The only Google app that I can see is the Play Store. But that's all I care about. I can then download and install whatever I need and avoid the bloatware. And best of all, I didn't get the "Just a sec" error, which seems to be a common problem.

Now I have the latest Cipher OS build with Google Play Store. It works! Thank you!

I have re-uploaded all Builds. (2022-05-12)

This time I've included Blur and Face Unlock.

Please test this Features and if its working well, it will be available also in future Builds.

If not, I'll kick it out.
[Galaxy Tab 4 Android Development] SteinbeckFan:
I can't get it to work. I set a PIN. Then I get to a screen called "Align Your Face". I momentarily see my face via the camera in a test circle. Then the app crashes with a message "Face unlock keeps stopping". I tried several times with the same results. The Face unlock app crashes every time.
[Galaxy Tab 4 Android Development] crazydrive22:
OK, that's not good. What device do you have?

If it's one of the Millet a logcat would be nice.
[Galaxy Tab 4 Android Development] SteinbeckFan:
My tablet is a SM-T530NU (matisse). Where would I find a logcat?
[Galaxy Tab 4 Android Development] crazydrive22:
Ok, I do not need a logcat from your device. I still have one from Matisse.
[Galaxy Tab 4 Android Development] SteinbeckFan:
What is Blur? In the camera app, the only implemented effects are the first 3: Mono, Sepia, and Negative. The remainder do nothing.
[Galaxy Tab 4 Android Development] crazydrive22:
Blur means to make your Background blurry, if you slide down the Settings. But it looks like it's not working as it should. I'll kick that Stuff out with the next Build.
[Galaxy Tab 4 Android Development] crazydrive22:
Sorry Guys, it looks like Face Unlock will not be available for our old Devices.

I'll remove it with the next Build.

If someone really, really needs that Feature, It's fully implemented and working in crDroid 7.
[Galaxy Tab 4 Android Development] SteinbeckFan:
Just verified that GPS is working. What's confusing and misleading is if WiFi is enabled, it appears that the tablet is receiving GPS, when in fact it's pulling location data from WiFi. Only by turning off WiFi, and in my case taking the tablet outdoors, can true GPS data be tested.

I used an app called GPS Data by EXA Tools. Also took camera pictures with GPS location turned on. Both methods proves that the GPS radio is working.
[Galaxy Tab 4 Android Development] crazydrive22:
Wifi (and sometimes Network) are often used to find better GPS-Positions. There could be an Option in Settings to deactivate it but i'm not sure.
[Galaxy Tab 4 Android Development] SteinbeckFan:
The reason why I wrote about GPS is because the above person posted in LOS 18.1 that GPS wasn't functioning. But it certainly is in CipherOS 11 (based on LOS 18.1).

What isn't clear is whether a non-functioning feature is caused by CipherOS 11 or LOS 18.1. It would seem that if something is working in LOS 18.1, it would also work in CipherOS 11. Or am I wrong? Where should bugs be reported?

Yes, there is a setting.
[Galaxy Tab 4 Android Development] crazydrive22:
Well, i'm using the Source from @matteo0026, who is building LOS18.1 and therefore anything what is working there (GPS in this case) should also work in CipherOS and crDroid.

If it's vice versa, Matteo should be tagged to have a look at it.

Hi @crazydrive22, (aka Martin)

TWRP link not working just checked 230622. Still no mirrors on AFH.

Link to XDA, just a link to Respository in Team TWRP, useless as Each file for your device is only available on TWRP app. @matteo0026 should upload on Telegram, as has been done for ROMs, when AFH is down.

[Galaxy Tab 4 Android Development] SteinbeckFan:
Was able to download the latest TWRP and ROM. Dirty flash failed. Had to start over from scratch. Seems like the norm.
[Galaxy Tab 4 Android Development] crazydrive22:
Dirty flash is working, as long as you also flash your GAPPS-Package (and Magisk, if needed) directly after the ROM. I don't know why the ROM is doing that s**t.
[Galaxy Tab 4 Android Development] SteinbeckFan:
I erroneously thought the purpose of a dirty flash was to not wipe or flash the GAPPS-Package and preserve all installed Google apps.
[Galaxy Tab 4 Android Development] crazydrive22:
You don't need to wipe anything. Just flash it dirty like the ROM. The Gapps don't get overwritten by this Action, as long as you use the same Package but the ROM is happy and booting.
