------------ Short Background --------------------

There are many custom roms for A20 while no roms for A20e. But two phones are very alike. Both uses Universal7885 SoC as base, have same GPU (Mali-G71) etc etc... And because we have a vendor partition, all the device specific files are in there. So this ROM works like a GSI, but for Samsung phones, for Universal7885 phones, for A20, A20e. Only difference is kernel and dtbo. All ROMs are ported by Gabriel260.

------------------- Working and Not Working----------------------

Same with A20.

WORKS:

RIL (Calls, SMS, Data)

Bluetooth

Wi-Fi

Camera

Video Recording

Video Playback

Audio (Record and Playback)

Sensors

Flashlight

DOESN'T WORK:

VoLTE and bluetooth calls (Blame Samsung for that)

Some people have a20e twrp which has a10 prop value. Which prevents installing. Install TWRP from the one in downloads.

If the phone is stuck in black screen after install, just soft reset the phone

Seriously, I don't get what you mean. The lineage OS boot perfectly with my phone.

Have you tried forcing the phone to reboot? That bug can happen. If you rebooted the phone and blank screen was greeting you. It is most likely to be solved by soft reset

It may be I did something wrong or that I didn't try hard enough, I'm not an expert on flashing, I only flashed my phone like 3-4 times and my Tab3 10 like 2-3 times.

I tried several times restarting, it didn't work. Maybe a step-by-step guide would be useful.

I apologize for not previously being constructive. Your work and that of other developers here on XDA is very important.

If a new update for Android 11 comes out how am I meant to update the stock rom
[Samsung Galaxy A20 ROMs, Kernels, Recoveries, & Ot] Xellerate:
How would I change the charge animation on this ROM, like the animation that plays when you plug in the charger
[Samsung Galaxy A20 ROMs, Kernels, Recoveries, & Ot] Crrrr:
My understanding is that you flash with Odin the stock firmware (BL, AP, CP, CSC), then you flash the TWRP (AP) with Odin, wipe everything, then install the custom ROM.

Before doing this, make a backup of your files.

You can also backup the entire system with TWRP in case something goes wrong with the new firmware. To return to the initial system, after a complete wipe, you flash in TWRP the resulting zip files.

You can also use a backuo app. At the moment, from my own research, the most user friendly app seems to be Migrate, available on Google Store/Aurora Store by BaltiApps. There are tutorials on YouTube on how to do this. My understanding is that in some exceptional cases, you need some maanual tinkering to complete the backup -see tutorials.

Please note that Migrate needs root. There are also other backup apps that do not need root, with different level of efficiency.

I haven't yet used Migrate, will try it after the Android 11 firmware update.

So the idea with Migrate is that you backup your files, apps and phone settings in some zips and after reinstalling the custom rom, at the end you also flash with TWRP the Migrate zips.

The above is solely based on my few months own research and experience, so you should do your own research.

[Samsung Galaxy A20 ROMs, Kernels, Recoveries, & Ot] therobbot:
I'd like to double the question from Naksuhd. I'm thinking about buying this phone and would like to know if there are any stable alternative ROMs for everyday use before deciding.
[Samsung Galaxy A20 ROMs, Kernels, Recoveries, & Ot] Crrrr:
Hi, I wasn't able to find a ROM for myself for this phone.

Personally I use AndyYan's Unoficial LineageOS GSI 18 (https://xdaforums.com/t/gsi-11-lineageos-18-x-gsi-all-archs.4205461/), but with no Gapps, as I was looking for a de-Googled phone.

Apart from a few bugs, the GSI is updated monthly and is usable on a daily basis.
[Samsung Galaxy A20 ROMs, Kernels, Recoveries, & Ot] Naksuhd:
Can someone try porting AOSP Extended? It seems to be good rom.
[Samsung Galaxy A20 ROMs, Kernels, Recoveries, & Ot] or23_72c:
Strange that 2 of the ROMs don't work for my phone. I only tried 2 so far. they worked before installing android 12 on it. Lineage OS just shows a black screen even after doing everything suggested. Project Sakura just bootloops and i tried the same things with it as well. Wouldn't be surprised if Android 12 "broke" something. I can flash the stock ROM, root it and install TWRP that way just fine.
[Samsung Galaxy A20 ROMs, Kernels, Recoveries, & Ot] stevamirkovic:
I lost 2 days to figure it out and almost gave up. So, if you can't install lineage or any other ROM from the list above, you need to flash stock android 10 from this link:

https://androidfilehost.com/?fid=8889791610682876823

Then, flash the latest TWRP from the 1st post, and finally, you will be able to flash any of these ROMs. I successfully installed lineage.
[Samsung Galaxy A20 ROMs, Kernels, Recoveries, & Ot] or23_72c:
anything to look out when flashing the custom ROM in TWRP? do i wipe the storage or not?
[Samsung Galaxy A20 ROMs, Kernels, Recoveries, & Ot] stevamirkovic:
I personally wiped everything, Dalvik, Cache, Data, System, even internal memory. I installed it from SD card, plus Nik Gapps, and just rebooted from TWRP to the system. Everything works well.
[Samsung Galaxy A20 ROMs, Kernels, Recoveries, & Ot] or23_72c:
Now it finally works. Thanks! Too bad the instructions weren't posted and that they are this strange.
[Samsung Galaxy A20 ROMs, Kernels, Recoveries, & Ot] Crrrr:
Yes, when I tried to install this rom I had Android 11 installed and it did not boot. Haven't tried flashing Android 10 before.
[Samsung Galaxy A20 ROMs, Kernels, Recoveries, & Ot] Crrrr:
Is this the last Androoid 10 stock version?
[Samsung Galaxy A20 ROMs, Kernels, Recoveries, & Ot] stevamirkovic:
No, it's one of the first versions of android 10, maybe 2nd release, from Apr 2020. But for this purpose just to fix the partition tables and downgrading after already installed android 12 ROMs, it does the job and allows you to install for example Lineage 18.1 or similar.
[Samsung Galaxy A20 ROMs, Kernels, Recoveries, & Ot] or23_72c:

LG v50s

5G Single Sim

i have LM-V510N (SKT version)

i tried to follow the universal unlock method using edl mode

https://xdaforums.com/t/guide-lg-g8...nlock-and-magisk-root-using-firehose.4221793/

it all went well until i had to boot into fastboot, then i had issues cos i cant find a method to get into the fastboot of v50s SKT version.

i tried using vol- and pwr, and all the button combos that i found on google and no luck.

i tried using adb reboot fastboot, adb reboot bootloader, but those commands simply rebooted the device normally,

i have used fastboot many times for my LG G6 and its worked well but not on my V50s

Any help would be appreciated!

[LG G8X ThinQ Questions & Answers] TeeCity:
How did you relock the bootloader as I have the same model.

I bought the model from eBay and it came from Korea but I want to get rid of this "lock the bootloader error" when it starts as there must've been some custom rom installed but it now has the factory firmware.

Tried many ways including LG UP and changing boot partitions a and b, i then got into fasboot coz any other method wouldn't allow me to enter fasboot as it would just reset!

Locked the bootloader but it still does the same thing 🤦🏼‍♂️

Any help would be appreciated! 🙏🏾
[LG G8X ThinQ Questions & Answers] trungsypro:
you follow the instructions of the article above. go to fastboot step, you use adb pc by command:

adb reboot bootloader

(Adb debug must enable in developer )

go to fastboot

then use command

fastboot oem unlock
[LG G8X ThinQ Questions & Answers] TeeCity:
I've tried all of what you have stated but it just reboots as the user Eriko3o has stated.

I've still got my G6 and it doesn't do that at all as everything goes smoothly so I'm stumped 🤷🏽‍♂️

I followed the instructions, now I have bootloader unlocked but happened the same for fingerprint... Is not working
[LG G8X ThinQ Questions & Answers] trungsypro:
dThat's right. I've searched the forums, but there's no way to fix it. it's a bug that lg announced. If you want fingerprint to work, you can only lock the bootloader and run the firmware with LGUp
[LG G8X ThinQ Questions & Answers] trungsypro:
B If you want to lock the bootloader, you must download the firmware with lg up then go to fastboot and use the command to lock the bootloader again : fastboot oem lock
[LG G8X ThinQ Questions & Answers] TeeCity:
I've tried all that but the phone just restarts after the command and I don't get the option to do it on the phone coz it just restarts.

I've had no issues with other LG's with this method, just this one 🤷🏾‍♂️

As outlined above I even swapped partitions from diff firmwares to get to the lock bootloader screen, I enabled it but it still persists so I'm stumped.

[LG G8X ThinQ Questions & Answers] iMarzateD:
I have a problem when I want to downgrade my v510n. Since it took me almost 5 hours to unlock the bootloader and flash the root with magisk because of the drivers. Now I have all I wanted but I also got the fingerprint error and I've seen that as you say, it can be fixed by using the oldest available ROM for the model and calibrating the sensor, and then updating to Android 12 again. But I can't use the LGUP because when the phone is on my PC recognizes COM 5 and 6 ports and the program reads them as "Unknown device", and if I turn off the phone on EDL or download mode it recognizes 9008 COM6 port but the LGUP don't recognizes anything and asks for a device. So basically I'm stucked on Android 12 without fingerprint. Is there any way to downgrade from this point?. I already installed like 10 different versions of the Google drivers when I was trying to unlock the bootloader, so at this point I think it isn't a matter of how the PC detects the device neither being on or off.

Hi,

I can't seem to find any custom recovery for gionee f205 with mt6739 chipset. So I tried porting similar mt6739 unofficial twrp img but it is also not working. Any custom recovery would be alright. Please help
[General Questions and Answers] lopestom:
You has experience flashing Custom Recoveries?

Share all specs from your device and let me know how you tried Porting.

Maybe need this? Gionee F205 / F205 Pro DA & Auth
[General Questions and Answers] Pnidhin:
Thanks, I have zero experience and have only started. I have already ported the custom recovery to my device using carliv image kitchen tool from here. The TWRP custom recovery is working perfectly but I can't confirm it as I have been searching for a week for a custom ROM(Oreo or later) to flash for my gionee F205(nougat) and can't find one. I have started trying to port the stock ROM of GIONEE F205 PRO which is Oreo and also treble enabled. Both have little differences but the same chipset(MT6739). But as of now nothing has worked. Could you help with that?

Or is there any custom ROM I can flash? Can I port from this non-treble device to an treble enabled ROM.

Also I tried Flashing the Stock rom of F205 pro excluding the Preloader using SP Flash Tools. But it return a error "PMT changed for ROM, it must be downloaded". So I tried to format except the bootloader and it too returns an error "ERROR : STATUS_SEC_WRITE_DATA_NOT_ALLOWED(0XC002000C).
[General Questions and Answers] lopestom:
You not need Custom ROM to test Custom Recovery. Now you need confirm that your file work good as you confusing here: "The TWRP custom recovery is working perfectly but I can't confirm it as.."

If you know that your TWRP work "perfectly" so the "issue" SOLVED. LOL

About Custom ROMs MT6739 stock Nougat:

I did a quick search in some places I know and the news is not good. I didn't really see any custom ROM for MT6739 with Nougat kernel.

Without a kernel upgraded to Android 8.1 you will not have much chance of installing the GSI ROM.

It is not just installing the stock ROM of another similar device or of the same company! It is about something that will take time and may have many errors to correct because companies that sell MTK devices do not provide all Source Code files to make a new kernel. So you can usually even ask someone with experience to do something, but without the full Source Code, then the chances are -100%.

So you can even have a Custom ROM from another MT6739 as long as it is with the Nougat kernel. Obviously there will be items to be solved for your device or suddenly not. As I have not seen any MT6739 Nougat with Custom ROM, then I cannot help further in this context.

If I had an MT6739 with Nougat then I would look at some MT6737 with Nougat because there are a lot of Custom ROMs for these. But remember that the MT6739 can have 32 bits (arm) or 64 bits (arm64) and that will influence something.

I myself have a 64-bit Nougat MT6737T that has RRMix Oreo 8.1 and works great!

So everything will depend on you and your time to do the PORT and the necessary tests because it will be a learning experience for yourself!

Good Lucky!
[HTC Vox] aaronb532:
I bought a used S710 on ebay and it has some body damage so I'm going to replace the entire housing. While I'm at it I'd also like to get rid of the blue back lighting on the keyboards (mainly the qwerty one). Is there anyway to replace the LEDs with something easier to read, like white? For some reason the blue seems difficult to me.
[HTC Vox] 128MB:
sure, everything is possible.

But, those leds are really really tiny and difficult to solder :)
[HTC Vox] Phrak:
You're not the only one. I've got 10/20 vision and zero colour blindness issues, and I still have issues reading the blue backlit chars. What a dumb idea that was!

GL replacing the LEDs though, they would be tiny if they're individual LEDs!
[HTC Vox] frauhottelmann:
I think some tech geek could do this for you! Although then, warranty would be gone!
[HTC Vox] aaronb532:
Yeah, I'm not too worried about warranty since I bought it with a broken screen on ebay!

I went ahead and did the housing swap without changing the LEDs. There's no way I have the skill to replace those tiny things, and it wasn't worth paying someone to do it.

Thanks for the replies anyway.
[HTC Vox] frauhottelmann:
Well I thought you might have a friend with the skills to do it! Otherwise it's a pretty difficult task, the heat destroys the circuit bord very fast, touch it too long and it's gone...for ever! :D
[HTC Vox] ollyk2:
I would love to do that - I take it I am not the only one who has trouble focusing on the intense blue LEDs?

[HTC Vox] aaronb532:
That's all I needed also, but I could only find full kits on ebay.
