S20 ultra Live Demo Unit fully operational... permanently? - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

Hi everyone.
I've just bought this LDU device to a guy, and it seems to be fully functional (excepting some minor things, I can make phone calls and use 4g/5g data connection, etc).
Anyway, I'm a little bit scared that something stops working suddenly, mainly because of the patches that have been applied to make it work, specially for the IMEI (these devices originally don't have one, so it's "patched").
Another thing is that it comes with Android 10, and I'm not sure if I can install another ROM with Android 11 without breaking the patching that makes it work so far.
Anyone with experience with LDU devices could please share some information about it?
Thanks in advance!
Edit1: After some days of testing, I've found the following issue:
-Cannot update via OTA, CSC is WWA which I haven't found anywhere.
-Samsung apps like Pass and Secure Folder don't work, probably due to Admin mode (despite no root app is installed), or it may be related to the CSC too.
The rest keeps working fine so far.

This sounds like a stolen phone i'm afraid. Patching an IMEI is considered illegal.
Any device that has a cellular modem in it (for calls and data), MUST have an IMEI.
If the seller said it didn't have an IMEI, he's lying and you are potentially dealing with a stolen phone.

Thanks for your reply. I thought it was a stolen one at first also (although he told me it was part of a payment from the phone store he works on), but then he had the white box of the LDU devices, so I don't think you can get one of those easily.
Anyway, this device obviously came with a cellular modem because it's working, but I guess the IMEI was patched somehow after reading it in some forums, but not sure. In fact, if you have a way to confirm it, I would be more than happy yo test it and publish the results.

Hi have you found any new answers or can you give me a link to where you've seen some answers? I'm using a Note 20 ultra LDU and I'd love to upgrade to android 12 but I wanna be sure I have enough information before i try anything.

Hi I'm using a Note 20 ultra that was previously an LDU. It came on android 10 like yours, I've currently upgraded it to android 12 via odin and everything still works fine. LDU are fully functional phones put in a demonstration mode and void of imeis, aside that nothing wrong with them. You might wanna install a new battery tho since they're batteries are quite overused because they were Live demo units....

Hello, i have An Galaxy s21 ldu and im wondering how to get it to work. I tried getting it an imei but all of those apps dont work. How to get it to work?

Galaxy Tab Pro 10.1 wifi stock firmware needed - how to restore to stock?

I have been scouring the internet for a while and cannot seem to find a way to revert my tablet back to stock. I tried the Lollipop firmware for a while and wanted to restore the tablet to possibly sell it. I can't find any method to recover it nor the files. The full model number is SM-T520NZKAXAR. It is the wifi only model. Can anyone help me please? I also currently have the TWRP recovery on it.
Thanks.

Thank you but I've looked there. I can't seem to find a match for my model number or any USA model. I read somewhere that the cellular south file will work but I'm a little hesitant to try flashing it. Mine is the WIFI only model.
If that were the case, it would either be a T525 (LTE), or possibly a T521 (3G). So anything listed as 'SM-T520' on Samfirmware should be OK. Having taken a look the US is not listed there. I have seen the Cellular South (XAR), as the possible option. But I doubt it has anything to do with any 3 ~ 4G connectivity, as the T520 has none.
It's possibly worth mentioning that these 'codes' (i.e. XAR), isa CSC Code. e.g. retail location in most cases. So assuming XAR is the USoA then this would be your choice.
Just one thing that you probably already knew, but is it really worth downgrading back to stock? The Knox Flag has already been blown. So NO KNOX on said Device ever again. Which would be about the only reason I could think for downgrading back to stock. Which IMHO would be a touch immoral if you wanted to resell it to someone who otherwise wouldn't have a clue.

def not mine was in deep sleep mode and i didn1t know it and now i use temasek ,it`s out of warranty ofc but bugs and error and lags from bull**** sa,sung apps are gone. cyanogen 13 modded flies like 5 times more than stock i play on tablet do a lot of stuff never had any problem in almost 1 year i can do offline backup a lot of perks.at some point when s3 will come i will sell it like this 32gb sd card leather case,i love this device.so no point going back to stock ever i always flash every new device
Thanks. I may give the cellular south file a try someday. The latest Cyanogenmod is working well. I was having problems with one of the older versions. The touch screen was acting goofy sometimes.
Have you tried https://samsung-firmware.org/?
Cellular South *is* the USA version. If you want to restore to US stock version, Cellular South is what you need. I don't know why they name it that way.

Test Device with unlocked bootloader - now what?

Hi guys
I do have an unusual situation here. Got a Honor View 20 Test device (or presample) directly from a Honor guy. I'm really happy about it as the bootloader is already unlocked. Okay, I honestly don't know what's the plus about it as I can't find a TWRP for this one.
Anyway, my main issue is the installed test ROM:
It shows:
Model: VNA-L29
EMUI Version 8.1
Android Version 8.0
Internal Memory 32GB
RAM 4GB
Using DevCheck System Info App it shows the truth:
Android Version 9.0
Internal Memory 128GB
RAM 6GB
There are some testing apps on it which I can't uninstall. One of them locks the phone after some days if I'm logging in. I have to do a hard reset to make it work again.
Updating the ROM in Recovery doesn't work. Uninstalling the app doesn't work. I'm thinking about trying to update to an official ROM thru DLOAD or HiSuite but this would lock the bootloader I guess - if it's even possible. So if I would be able to install TWRP and an official ROM to use with TWRP I should be able to update it.
Any idea? Every help is appreciated! Thank you!
---------------------
Update: I took the risk and just flashed the actual ROM 238 from androidhost.ru thru DLOAD. Phone works like charm and device still has an unlocked bootloader.
Thanks!

I got this one for free so I wanna make the best out of it.
Huawei/Honor devices cannot be unlocked. So there is no active community with CFW developements so there is no point whatsoever of going in to shady sites and trying to 'unlock' your device bootloader.
You can try to update with download method(as it is the only way) If you brick the phone just recycle it and be done with it. There is not many options.

Thanks for your feedback. As I wrote at the end of my first post I updated with the regular firmware. Everything works smooth and the bootloader is still unlocked.
I'll try this at the weekend with the manual I found on XDA. There are CFW for a lot of Honor and Huawei devices but the firmware is quite old so I'll not even try .

Why would you say that when it is clearly possible? My Honor View 20 is unlocked and has Magisk running on it. There are other people with an unlocked bootloader, just look at the "Root Guide" Thread.
The problem is getting the unlock code. As far as i know there are no trustworthy providers at the moment so please be carfeful!

Because there is no official way to unlock phones bootloader(you cannot get unlock code, at least officially) If you are willing to give your personal info in shady sites, that is your own risk and fault if your IMEI get's in to wrong hands....
So basicly im guessing there is 90% locked vs 10% unlocked Huawei/Honor phones in the world. :good: Congrats if you are 'geek' enough and went true the shady process to get in those 10%. BUT there is no active developements of CFW. Yes there is some but they are unstable...
Oh yeah and official security apps(like banking, to pay with nfc) for security reasons check phones bootloader and if it is rooted/unlocked then you cannot start them. I dont know if it is worth the trouble anymore to bang on your chest and root your android just because of ''freedom''....
Again, it IS possible, thats what i'm saying. Nothing more, nothing less. So if you say 'its is not possible to unlock bootloader' then thats just plain wrong. Everyone should be able to make an informed decision for themselves, we're not children anymore. I definitely agree that you shouldn't give your data to some shady site.
In addition, i'm not sure what unlocking and rooting yout phone has to do with 'banging on your chest'.
Although the advantages may be minor nowadays, they are still there. The banking apps (i'm using) work just fine. If you are used to rooting your phone then its hard to accept all the restrictions
Regards
Previously ive rooted all my androids aswell. But ive stopped on my last main device(4years ago) because when you have full official support, whats the point? The hustle of manually flashing weekly because of updates and bug fixes... Meehh. Its not 2010 anymore when it was 'cool' to have a rooted phone(thats why the chest expression. )
If the device is like 3years old and dosent have update support anymore from the manufacturer
then it is a different story. Then you can flash newer custom android version and play with the device more to extend phone pocket life.
Ehmm i guess it is in country's security law or something. Because here where i live none of the banking apps work if you have rooted phone, when you open it just sayes that security check failed and error code(that you have a rooted phone)
neither lot of cupon apps where there is your sensitive info. ???Even mcdonalds app dosent let to use cupons on my rooted phone.
I have older rooted android to play on in my spare time. ?
Think we're on the same page anyway, right?
Guess i am lucky that i have rooted phone with apps and updates working. Though, i have to mention this again, i'm not sure what that has to do with being cool. Ppl are not bragging about it (at least no one i know ever has), its just that i like to have as many customization options as possible. Coming from a Xiaomi device i felt pretty restricted at the beginning
Doesn't matter, have a nice day!

Call Recording and Indonesia ROM

Just got a Redmi Note 8 Pro with Global ROM and discovered that call recording won't work due to Google/Android Pie limitations.
After some searching, I found (on this forum) that the Indonesia ROM supports call recording on this phone.
Here are my questions:
1. Will burning a different ROM affect my warranty?
2. Will I lose any functionality by switching from Global to Indonesia ROM, and if so, what? Specifically, will NFC functionality be affected?
3. If I ever do a factory reset, will the phone revert to Global ROM?
4. I found the Indonesia ROM files here. There are three files called Recovery, OTA, and Fastboot. Do I need them all? If so, do they need to be burned in any specific order?
5. Where can I find complete instructions for burning the Indonesia ROM? I am new to Xiaomi, and the last time I burned a ROM to a phone was 5 years ago (Samsung); I don't remember anything, so I'd like instructions that assume nothing and don't skip any steps (instructions for intelligent dummies). I found these instructions for installing TWRP, but there's nothing about what to do next, and there's a list of pre-requisites with no explanations (Unlocked Bootloader, Phone Drivers, ADB and Fastboot Drivers), making the instructions insufficient for a noob like me.
Thanks much.

Hey,
Before going any further you first need to make sure what region is your phone. Is it a Chinese phone (bought from AliExpress for example) or a real Global phone (bought from a local store/official retail). Because you could very well own a Chinese phone shipped with a Global Rom flashed on it and this could result in some problems for you in terms of what you can do with it and how you can do it.
If you bought/received a phone with already unlocked bootloader, you should return it.
Unlocking bootloader should only be done by you when you need it.
1. Technically unlocking bootloader, ESSENTIAL step prior flashing anything, void your warranty.
However and that's what is interesting, if at some point you decide to flash back your original region rom (here Global) and lock back bootloader, none will know but Xiaomi servers you once unlocked this device certainly not a local reseller. So in term of warranty you should be safe, that is of course unless you brick your phone doing stuff you were not supposed to do with a locked bootloader if you are following.
2. If not mistaking, I think you loose NFC. Indian phones for sure do not have NFC at all, for their version, the chip was replaced with a 2nd SIM card tray (not shared). Not sure if you read the functionality afterward using rooted tricks.
3. No that does not work this way. When you are running a Rom, any version, if you factory reset that room, you just return to installation screen of that given Rom.
To return to Global Rom, you will need to reflash that Global Rom using the same method you did successfully flashing the Indonesian Rom (or any other rom) for example.
Would be wise to first download the exact version of the Rom you are currently using on your phone for archives purpose (BURN IT on good quality medias!) to revert back to it when/if needed. You can also archives OTA updates of that version you may not have taken yet to apply them manually if you ever revert back to that Global Rom and want to.
4. Different versions depends on what you are doing. In your case Fastboot version is what you need at the moment. You can find all different kind of versions of Roms for your RN8PRO on that site
As for the way to flash them, order and everything, you will need to look for guides online,
I dont think any order matters, just make sure to flash them all before rebooting disconnecting device. But if you are unsure of what you are doing, you'd be probably best using a tool such as MiFlash.
5. Here you can find one from the MIUI community website guiding you through the use of MiFlash to flash a stock Rom on your device.
Just note you do not have to use any tools to flash the .images of all partitions, you can easily doing it from command line using fastboot flash command one after an other.
Also note that installing TWRP is usually not needed to flash stock Roms (unlike flashing custom roms). Trying to mess up with the recovery partition is actually what seem to brick most of the devices.
However please note UNLOCKING your BOOTLOADER is MENDATORY.
Hope this helps.
Regards,
doesnt matter if you switch to any rom variant .i have switched mine to indonesian ,europe and indian and alll worked fine execpt indian version felt a bit laggy .just download the fastboot version of the rom and flash it through mi flash tool xiaomiflash .your bootloader needs to be unlocked and dont forget to check cleann all button in mi flash and dont check clean and lock
I have got global version and changed imei with unlocked bootloader. Can i flash indonesian rom without lose f my imei?
Thanks in advance for your answers
Muad.Dib,
Thanks for your detailed reply.
If I understand correctly, unlocking the bootloader voids the warranty just the same as rooting the phone, so if all I want is to get call recording, I may as well just root the phone and save the bother of flashing a different ROM.
Does that make sense to you, or do you see any advantage to flashing a different stock ROM instead of just rooting the phone? From past experience I've seen that rooting has additional benefits anyway.
BTW, I bought my phone on Banggood. It was advertised as Global ROM, and that appears to be what it has. As soon as I turned the phone on it updated to MIUI Global 11.0.2.1; I don't know what version it was before the update.

You're welcome, I am happy if I was useful to you in any kind of ways.
Well yes and no. Yes apparently you 'could' achieve call recording when rooted (yet I still fail doing so even if I installed the default MUI apps module I got from Telegram group. The setting to automatic recording is set to on yes, but I dont see recordings in the supposed destination folder nor I can see a simple button to record any voicecall I used to have on older versions of Android. Me failing to make it work - I did not try very hard to be honest - does not mean you cannot find someone who succeeded into doing so in that telegram group for RN8PRO).
That said it would not be a 'native' solution, just a patch/workaround. If it works well great, if not, well...
On an other hand by flashing to a Rom which does support it natively, well you are covered for the use you need.
So the advantage I see (with the included disadvantages) is better support for the function which is not supported for privacy reasons en Glob/EU market.
Does that come at a price?
Probably.
For example are you ready to trade off NFC for native call recording support? That may be a choice you have to make in the end. Again that said, if you root your phone on that new Rom, install NFC drivers manually as root (I see no reasons why that would not be possible after all) you may be able to patch NFC on that other Rom since unlike Indonesians market phone, you do have NFC hardware.
For example, myself, I wish I could have made that kind of bargain/trade off, giving up that NFC feature I have no need for, to get 8GB or Ram + 2x Sims + SD and not an hybrid tray. Unfortunately that's not the kind of trade I could make here in EU unless I would have ordered directly from Amazon.in (assuming that would have been possible) or third party website, but that was not possible for warranty reasons among other things.
Hope this helps.

Yes it does as it is officially available in every variant expect indian variant.
UPDATE:
I finally had the time to test the MIUI-default-apps Magisk module available for download on Telegram group, originally made for MIUI 11.0.1.0, and it works properly on MIUI 11.0.2.0 EEA. Does not require changing Rom.
Hope this helps.
Well, I have finally started the process, but got stymied by the Bootloader Unlock tool (Couldn't unlock. Please unlock 168 hours later.). Quite frustrating. I see that a lot of people have this problem and had to try again more than once, waiting a week between attempts.
Is there a workaround or do I just have to wait a week and hope for the best?
Also, assuming all goes well and I eventually manage to unlock the bootloader and flash the Indonesia ROM, do I use the same tool to re-lock the bootloader (in order to restore the security of the phone)?
And if I want to unlock again in the future, will I again possibly get the "wait and try again next week" message, or does that only happen the first time?
Thanks.

UPDATE:
I finally had the time to test the MIUI-default-apps Magisk module available for download on Telegram group, originally made for MIUI 11.0.1.0, and it works properly on MIUI 11.0.2.0 EEA. Does not require changing Rom.
Hope this helps.

Well, I have finally started the process, but got stymied by the Bootloader Unlock tool (Couldn't unlock. Please unlock 168 hours later.). Quite frustrating. I see that a lot of people have this problem and had to try again more than once, waiting a week between attempts.

No workaround, you just have to wait (and yes I know how freaking frustrating it was for me...). You can even start meditation classes meanwhile it helps

It depends on what your the flavor of the phone you got. You may want to have a look at that other thread Relock bootloader after flashing ROM Indonesia where we actually covered this exact subject
The good thing about that 7 days wait period is you can gather all the intel you need to be 100% ready when the time come to seriously mess up with things.
So you know, once your bootloader is unlocked, first thing you will want to do BEFORE anything else, is blow off that security which needed Auth Account to unbrick account (ONLY WORKS FOR PIE, ANDROID 9 MIUI VERSION BEWARE).
All information is here: [GUIDE][INFO][PSA] Redmi Note 8 Pro - Megathread

The waiting time is for one time only (THANKS GOD!).
So if you relock, beside having to get your hands on the unlock tool once again and have added the same infos as for the first time in the phone, you will be able to unlock right away.
That's at least a good news
Hope this helps,

Yes of course.
It is a module you can find on the Telegram group called "Redmi Note 8 Pro | OFFICIAL".
Like me you will have to go in there even if you do not use Telegram.
Once there and you got the /notes it is called the default apps.
I cannot share it myself here because I am not the developer of that module, as you can understand that's against forums policies.
All I can tell you is it works correctly on EEA MIUI 11.0.2.0.
Good luck!
Hope this helps.

Thanks man, I got it! ?
I have disovered that there are different NGC protocols and that my Redmi Note 8 Pro does not read NFC cards of some protocols. I'm wondering if it might not be a driver issue. where would I look for NFC drivers?
Thanks
Muad.Dib said:
For example are you ready to trade off NFC for native call recording support? That may be a choice you have to make in the end. Again that said, if you root your phone on that new Rom, install NFC drivers manually as root (I see no reasons why that would not be possible after all) you may be able to patch NFC on that other Rom since unlike Indonesians market phone, you do have NFC hardware.

Sadly I have no idea. I think you should make a new thread about this to get more visibility and probably more answers from people who actually knows the answer.
Hope this help.

Hey,
Sorry was AFK for a while. In case you still need answer, going to reply just in case.
Well there is not much to add, you simply install the module from within Magisk once it installed, you reboot, and it works out of the box, you go in the settings and you set it as you like.
Good luck!
Do i need to root before installing it ?

Just bought a new G8 AT&T LM-G820UM, G820UM10m. Best way forward?

Hi, I need some support.
Last week I bought a 'new ' G8 AT&T, unlocked phone, that will replace my beloved G7.
The G8 seems to work ok with my operator, here in Sweden.
It has Android 9, and the software version is G820UM10m.
I would like to get a newer android version and get rid of everything AT&T.
I have just read the guide "[Tutorial] Crossflash, Bypass OPID Mismatched Error", but not all the 64 pages.
My questions, before I begin my adventure:
Is this guide the most suitable for me, or are there newer better ways?
Which version of firmware is the best option for me, considering where I live, and my phones current state ? (From what I have read so far, LM-G820QM should be a good option.)
Which Android version is the best option for my phone? Should/Can I go for the latest version straight away?
Is the best source of firmwares https://lg-firmwares.com or where do you find get your firmwares from?
Thanks!

Lots of questions. The best version would be the most current version that has the support for the carriers in your area. Only you can decide that, sometimes we change which rom to use when we switch carriers. So, it would be best to find an 'open' version (QM) that also supports the needed bands for carrier.
And of course, the open versions have much less carrier specific 'bloatware'.
That guide is not only the best, it's the only So yes, that's what you follow. That site for firmware is good, there may be others, it's been a while for me. I'd suggest to do a full phone firmware backup before proceeding with anything. There are quite a few partitions you want a copy of, so rather than risk a mistake of forgetting one, just backup the entire device, completely.
then you can proceed without fear of being able to 'get back to original'. Good luck.
Thank you for your reply!
Good that it was the "one and only" guide
Last night I spent some hours trying to get things right.
I took a tiny step (since I didn't know better) and tried to replace my G820UM10m (AT&T, Android 9) with a G820QM20f version (US open Android 10) that I found.
Now I have don't have the AT&T bloatware anymore, but my phone says it has software version G820UM20f , and NOT G820QM20f .
I was hoping it would be QM, with as many bands as possible unlocked.
As it is right now it seems to be a bit "so so" with internet connection when I'm not on Wifi, so I need to solve that somehow before I can start using the phone for real.
(When I tried to install, it did go to a "fastboot" menu before I got it to "download mode". Maybe that wasn't so good..)
On the pages here there is a lot of information.. and I need to read up a bit more about it. And I might ask silly questions again
Thanks again!

You're welcome, no worries. First I'd say just because it went to fastboot before download mode, don't worry, that's nothing.
2nd, it's not uncommon for the 'info' page to be a bit off, it gets that info from different sources, and some of them don't get updated during this process. It's not uncommon for that info to be 'off'.
The best way to determine if you have the bands needed for your carrier is to install and app from playstore that tells you which bands you're connected to, one I remember is called 'lte discovery', but there are many to choose from.
You might want to consider traveling around a bit to see which bands are available and where, bands like t-mo 71 are towards the outer parts of the town I was in.
good luck, it's fun.

Thank you for taking some of the stress off my shoulders .
I will try the app and see if I can find out which bands that are in use here.
My plan now is to crossflash "G820QM40a...." that I just downloaded.
I haven't reached the "fun" yet, but when I get the hang of it I guess I can enjoy it more

Hi,
Nah.. Right now my mobile has "T-mobile" firmware-
It has tried to update, but fails without any failure message.
It might be that I am in Sweden, using a Swedish sim/operator.
I wouldn't draw any conclusions based on my situation

It fails. It can't read my current version, according to the error message.
I have crossflashed my mobile multiple times now, so I am not surprised that LG Bridge is confused.

Attempted with latest Odin with a firmware to flash it, would like to acutally use the phone with the current email that its being used. Anyway of getting around this without having to bring it to a store. Really would like to use the phone and possibly put TWRP on it and custom ROM
