When it comes to being a developer, am more of a hobbiest. Making a custom ROM is a tall task. It will take me a long time. Hence I said I can helps with parts of it.

As per your second question there are a few things to consider

1. You actually never delete all the partitions. For eg, you might only wipe the data and cache partition to flash an update. You also won't wipe other core partitions like recovery or bootloader.

2. A few years back, they changed how the OS partition works. In simple terms, there are two copies of it. This ensures seamless updating for OEMs. While you use a partition, the update is applied to the other one. Then you can shift to the updated partition. This has many benefits, like if something happens and the update gets corrupted, you can still use your phone.
[General Questions and Answers] OldNoobOne:
Thanks, so we can just wipe partitions or create new partition(like vendor etc.) but not delete partitions correct? I think only odin will be able to do that right?

I have another question if you dont mind- I upgraded galaxy J7 from Nougat 7.0 to pie 9, I was running Resurrection Remix Q using OrangeFox Recovery till few day ago, everything was fine but Q is a bit heavy for 2gb ram so I decided to reflash android 9 pie stock firmware but it just got stuck on bootloop. I installed twrp then flashed (Refined pie 9 Custom Rom) for the device but it wont flash beyond 35%, so I wiped everything, created vendor, RMM bypass then reflashed RR-Q Rom, this time it wont flash beyond 65%. Can you tell me where I went wrong? Thanks in advance.

Edit: I willtry to update twrp and check if it flashes rom
[General Questions and Answers] J.Michael:
Check the version numbers of the bootloaders in the two ROMs. If Q upgraded the bootloader, it might not be possible to downgrade to the bootloader in P.

Were you using stock N before upgrading to Q?
[General Questions and Answers] OldNoobOne:
Thanks,

yes I had upgraded from stock N to Custom Rom (N) Then Installed Pie Stock Image by mistake then upgraded to Custom Rom (Q).

The problem was solved by flashing (RMM State Bypass.zip) + (Refined Pie Custom Rom). But, I find Resurrexction Remix OS 8.6.6 by GonicTEAM ( https://androidfilehost.com/?fid=17248734326145728251 ) better than Refined Pie in performance & customizations for J7.
[General Questions and Answers] gorgorven:
I am not very familiar with the device or these ROMs. If you post error message/log, it might help. Try posting on the ROM support thread that you are trying to flash too. You might find help there....

Generally the pie ROM that you flashed, the forum thread would have mentioned all prerequisites, which might hold answers.

If you have twrp, fastboot, adb up... You are good to correct any mistakes made, albeit with some efforts.

Though there exists GSI Flashing Guide on XDA & on the internet, I found the above method by Dev GuruPrasadAH to be simplest working method for Galaxy M21; So I have put the quoted message above for anyone looking for a simple flashing guide for GSIs particularly for SM-M215G model.

Hi @OldNoobOne ! I also took devils alternative and bought this SM-M215G/DS hopping(against hope?) to get a custom rom someday. Good to see that you succeeded installing gsi on this phone. Thanks for your debloat list. Uninstalled those packages and using netguard to block unwanted network traffic. Im new to samsung device, vbmeta, dmverity, multidisabler etc. If it is not too much can you please summarise the gsi flashing method you followed for SM-M215G/DS from unlocking bootloader. Installed heimdall in my linux laptop and ready to go. Thanks in advace!
[General Questions and Answers] radikyrick:
Awesome! Thankyou so much for your quick response and elaborate details. Particularly the warning at the end part. Im collecting those zip files you mentioned above and I have linux only and dont want to use windoze and should learn to use heimdall instead of odin. Are you trying to say without a custom rom there is not much use in bootloader unlocking, custom recovery and rooting?
[General Questions and Answers] OldNoobOne:
Hey radikyrick, youre welcome.

1) [offTopic] ahaha i love to watch Linux Vs Win furious debates hereNthere; In short, as per my experiences as a user I conclude -

Linux = Cook & Eat (If you have plenty time) while Win = Packaged food (if youre in a hurry)

2) GSI, Custom ROM , Custom Recovery would need unlocked bootloader. For recent shamshung devices Rooting can be done using Download Mode too but that again needs bootloader unlocked as far as I know. [ Unless UhbuntuTouch comes out with an ODIN-like PC Flasher to get Linux OS (older cousin of andoid) on all devices including M215G without unlocking bootloader ]

Thanks :)
[General Questions and Answers] radikyrick:
There is heimdall available for linux to unlock bootloader and flash rom in samsung devices.
[General Questions and Answers] J.Michael:
I don't think Heimdall has anything to do with unlocking the bootloader -- it is an alternative to Odin for downloading to a Samsung device.
[General Questions and Answers] radikyrick:
Yes. Thanks for pointing out. But I didn't intent to say like that. My mistake:)

Hi@OldNoobOne ! @soulr344 in galaxy m21 telegram group is willing to develop fulltime for m21-2021. He likes to get in touch with you:)

[General Questions and Answers] OldNoobOne:
Finally, Thats wonderful news Radikyrick..awesome job bruh! (y),

but..there are two issues;

1) I got banned on telegram (t.me) by Rose Bot as I was pranking with Rose Bot ( I had kept her DP as mine & posted a few msgs so she banned me) , so i cant contact Soulr344 on t.me.

2) Also, I had made that $20.00 offer almost 3 months ago when the device was just launched (shamshung mustve sold a million of M215G by now already), after which I suffered some financial loses ( The rooster I had bet on had lost a few major fights in a row over a few weeks )

3) Radik bruh, look.. I can still make donate $5/month for a year to Soulr344, So if you could find some more donors for Soulr344 on telegram that would be really nice coz we could still have a ROM for M215G that way you know. All we will need is 3 or 4 more guys willing to chip in to pool the funds for soulr344.

Think about it ok? Also, to be fair If Soulr344 does make a ROM for M215G then anyone with the same device will benefit from it so its for the benefit of all users not just me right?

Thanks
[General Questions and Answers] radikyrick:
There is no rose bot here at m21 group.

You can dropby if you are interested. Completely agree with your other points. Not only m21-2021 but all the m21 users will also benefit because both models are same. Hope for the best:)
[General Questions and Answers] OldNoobOne:
1) Yup, i agree no Rose Bot in t.me m21 Group (I think Izumi Uchiha Bot manages that group) but I was banned from Telegram by Rose Bot, so if I try to log into t.me I get msg "This phone no. has been banned, contact telegram support", so I cant log into telegram altogether, its not about a particular t.me group. :-/

2) Dev Soulr344 doesnt respond to DM on XDA i suppose coz I had tried to contact him through reply on his-- Soulr344 TWRP for M21--post but he never replied. [ I was looking for an Identical TWRP for xiaomi RN10 which wont have A-B Slot to boot on just like M21 TWRP ].

What works with CAOS11 GSI so far:

1> MicroG

2> GCam (without Portrait mode), Open Camera works even better in daylight with Camera2API (Phh Treble settings)

3> Banking apps

4> 4G Data Calling not sure (but normal calls work haven't checked Volte), no call drops.

5> Under 1GB games work fine (no heating issue at 30 FPS)

6> TWRP Backups restore well if you don't try to restore Super Partition

7> NetGuard VPN works

8> Magisk 24.3 works, all modules flash well.

9> Battery backup might not be as good as Stock OS but 8-9% battery drain in 3 hrsof gaming at 30 FPS. Its 2 days since I charged the battery 92% and still 35% juice remaining.

#EDIT:

CrDroid 11 GSI- Works very well with lots of cusromizations , battery standby time is excellent but battery usage time is not good (1% drop in every 5 minutes even with native kernel)

I can use for it for selfie but nothing else. I want use like front display in rear display

If you have any idea, pls share with me

If you flash the Xiaomi.eu rom (weekly), you can also use it to record video, as well as, for selfies, music controller and notifications.

Hi Jim262

Thanks for the reply but my one GLAOBAL EUROPE version 12.5.2.0

Cant do much on rear panel with 12.5.2
[Xiaomi Mi 11 Ultra] kajalkmrctg:
Is it update to more usefull on next MIUI?
[Xiaomi Mi 11 Ultra] jim262:
T

Xiaomi has not released that feature yet to their global rom It is currently only available in their beta version of the China rom, which Xiaomi.eu is based on, so it has that feature available now in their weekly rom.
[Xiaomi Mi 11 Ultra] xwonic:
It's not pratical to be used like front display. you can use it to answer/reject calls or change music, but i can tell you the number of times i place the phone on the table facing down by the fingers in my hand

It could be used as a light source(bright white) for close up shots but then again you can do it with flash as well.

I wished they had replaced it for one of these Macro/microscope/nightvision/thermal/blackandwhite camera

and add a mirror that does square so you can see yourself instead of a amoled screen

I would also like to see somethings like on OPPO new continuous zoom lens.

Oppo introduces true continuous zoom lens for smartphones

It should be sharp at every step from 85 to 200mm

www.theverge.com
[Xiaomi Mi 11 Ultra] jim262:
However, with the Xiaomi.eu weekly rom you can also use it as view finder when making videos and using the rear cameras.
[Xiaomi Mi 11 Ultra] GuyWithRootedPhone:
everywhere except the camera's pro mode which oddly enough doesn't have the rear display support.
[Xiaomi Mi 11 Ultra] jim262:
Still in beta, so we can't expect everything at this point. However, the majority don't use pro mode anyways. Just like most people don't shoot in RAW, so the fact that a small minority of users aren't happy, doesn't really matter in the larger scheme of things. Patience grasshopper.
[Xiaomi Mi 11 Ultra] rowihel2012:
Xiaomi very slow with rear display functions updates

I need it to work with pro mode

Pro mode is perfect with sharpness option

It gives me amazing quality
[Xiaomi Mi 11 Ultra] jim262:
Im sorry, there's nothing anyone can do about that. The rear display combination with the rear camera is still in beta and whenever they release it to the general public, no one knows and whether or not it includes pro mode, there is nothing I can do about that, otherwise you can take my advice and download Xiaomi.eu weekly, which is based on the beta China rom to be able to use the rear camera with video features. BTW, who needs pro mode for selfies anyways?
[Xiaomi Mi 11 Ultra] rowihel2012:
Faces details are soft with auto mode

Pro mode has sharpness control

And has no xiaomi beauty mode that includes with auto

Try it with yourself

Go to pro mode

Increase sharpness

And shot

So faces and indoors photos are way better with pro mode

Colors are accurate too

....but better then wisdom is patience and tolerance, you either have it or you don't.
[Xiaomi Mi 11 Ultra] speedtripler:
I think there is more frustration with this particular phone because it was expensive ( by Xiaomi standards) and a lot of people who bought it are inexperienced noobs who want it to work like an iphone 12 pro max but even though the hardware is stacked the software is atrocious

Combine that with the low international sales count compared to the s21u etc and you're not going to have a lot of development going on

If I wasn't able to get the 12/512 for China mainland price I also would have bought another phone

The camera simply isn't as good as it should be and you will notice the 108mp cheaper regular mi 11 camera often takes more detailed pictures ( except zoom or night shots )

, if this camera was actually good they would have used it in the mi mix 4 and the mi 11t pro but looks like even Xiaomi know they dropped the ball here and tried to sell it on spec alone without the necessary software to back it up
[Xiaomi Mi 11 Ultra] jim262:
OK, does that mean you are incapable of flashing another rom? I merely am telling you that there is a possibility, whether you use that possibility or not is your choice. That doesn't require an answer that makes it out like it's an impossibility.

I can use it as a rear view finder and also read WhatsApp or other msgs on the back screen although I'm not sure why anyone would want to.....

[Xiaomi Mi 11 Ultra] xNAPx:
I can't see any issue with the rear screen on global ROM. Everything works although functionalities are pretty basic
[Xiaomi Mi 11 Ultra] jim262:
To see notifications, it must be applied in settings. The Xiaomi.eu rom has always had the ability to use the rear display as a viewfinder, as it is based on the Chinese rom.

Pretty Basic means? Do you see the red notification light on the back when you got a gmail for example? That's what i wan't. For Google, WhatsApp and so on.

Hi all, I just received my brand new POCO F3 phone today and I was hoping to unlock the bootloader and install a custom ROM. But when I tried to do that I got this message in the miui unlock software saying that I have to wait for 168 hours (7 days) and try again!

View attachment 5390475

Do I have to wait for that much time or is there a quicker way to do this? And if I do wait and try again will it again complain 7 days later that I need to wait for more time? Please let me know.

And also, do I have to use my phone regularly in that 7 days or if I just leave it turned on is that good enough? Please let me know what to do. And thanks in advance!
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] keyoke87:
No other way... Can only wait

Just leave your phone on, and leave it 1 side. And do not click on add account and device option again else your 168 hours countdown will reset
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] litetaker:
I see. Okay, I will just wait for 7 days then. It is such a bummer! I wish Xiaomi did not do this so that users can mod their phones right away. But it is just 7 days. So I will learn to be patient!
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] spaha-bih:
Is it necessary to unlock bootloader right after 7 days, or I can request to unlock now and actually unlock the bootloader after two or three months after?
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] keyoke87:
Yes u can always unlock any time u like after 7 days. So when i got the phone, i request to unlock right away, and use the phone first. My first unlock is only 1 month later
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Zimmster:
You can unlock any time, but not sooner than 7 days. If you try sooner the 7 day countdown will start again. better try a day or two later than 5 minutes earlier
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] spaha-bih:
Oh boy, I see I did not explained well, glad keyoke87 understood what I asked haha :D

basically what I asked is do I need to unlock right after that 7 days of waiting, or I can unlock later whenever I want.

I thought if I don`t unlock the bootloader right after 7 days, xiaomi will reset again countdown.

Anyway, I`ll have to wait for september to unlock the bootloader, since I have already unlocked it for Redmi Note 9s. A bit unnecessary from Xiaomi`s side, but it`s okay, I am waiting for Android 12 custom roms anyway.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Kokovitch:
The Countdown do not reset if you try sooner. It reset only when you remove and add a Xiaomi account.

When you try sooner, the mi unlock tool says the amount of hours remaining to wait.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] keyoke87:
If u press add account and device with the same xiaomi account, it resets too
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] pegasoc:
Exactly confirmed, as my countdown continued I tried dozens of times (maybe Xiaomi would give me a discount ahahahah) and the count never reset.

Their priority is to convince you to continue to use their MIUI OS, so they can upsell you some of their online services and use your data for statistics and advertising. If you do not use their software, they stop making money off you. It's just in their best interest to make you stay on MIUI. Maybe after that week your start to enjoy MIUI enough not to change it anymore.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Darkaeluz:
They had to do this to counteract people that bought their Chinese phones that didn't have a global release, slapped a bad MIUI custom ROM and resold them in other countries
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Zimmster:
Yes, making you wait a week is an annoyance (especially from a business point of view) but is only a temporary delay, the Anti Rollback feature is the main tool to block you, or a vendor of Chinese version, to exchange the MIUI version on your device.
[Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40] Ricky9111999:
nah, the main tool to block the weirdly moded custom roms are the locked edl mode on locked bootloader devices and the delay on unlocking bootloader.

back then (at least in SEA) the weirdly moded miui installed by third party distributors issue was BAD. it was widespread here and the mod were just bad user experience wise. most of them had lots of bugs (even by miui standards lol) and you couldn't update. so they started locking the bootloader and added timers, which did decrease the issue a bit.

but some were still bypassing through edl, which was especially bad and made it harder to fix since the moded rom often faked the bootloader unlock status so you couldn't unlock the device to flash an original rom, often needing you to short pins on the motherboard to bypass it through edl if i remember correctly.

the delay decreased the issue by quite a bit, but they were still bypassing it through edl, so they lock that also, which solves the issue. so i blame the third party distributors for this mess.

the anti rollback is just google tho.

back then you could apply your account to have special auth on the miui forums so you can still flash with edl and unlock the bootloader without having to wait, but i cant find any info on that now?

i know those account exist because my mi account is one of those account.
