Download Odin, download your phone specific Android 11 firmware file from a reliable site like Sammobile and extract it. Use Odin to flash A11 firmware (select CSC and not HOME_CSC) after putting phone in download mode. This will force a factory reset and you'll have to set up phone from scratch, but you'll be back to Android 11, stock firmware.
Detailed guides for the above procedure can be found on xda as well as YouTube. The process is the same across all recent Samsung phones, just be sure to download the correct firmware.

@enigmaamit, thank you for replying. I got all that. However my question would will this bring back the phone to the same way as I have bought it from the carrier! because since the update, every time my phone boots it doesn't have the carrier logo anymore. Yes I'm not a fan of carrier locks or logos on phones. I just wanted to restore the phone to where as I just bought it. Thanks again for replying

Only way to be 100% sure it works is to try it out I guess. If you're really unhappy with A12 and want to go back, I don't see any harm in trying.

What disappeared? Like what issues are you having? You will probably run into a lot of issues trying to install 11 after installing 12. ESPECIALLY the Ota 12...

I could use a little help guys

Hi guys I'm trying to flash Jovi's Custom Rom. I accidentally pressed the update button on my phone that allows the Latest update from t-moble to kill the phone so It wont charge. Luckily I have quite a but of battery power left and I'm franticly trying to flash a jovi's custom rom. currently I'm getting a "Failed" message when trying to flash on ODEN 3.12 here are the directions I followed to the letter but no success.
First Thing Your Going To Do Is Download Both graceqltetmo_N930TUVU1APGC_Stock_Deodexed.zip And N930T_Note7_Adb_Rootkit_And_Odin_Pack.zip Files From The Download Link Section Below.
2. Extract All The Files From N930T_Note7_Adb_Rootkit_And_Odin_Pack.zip Onto Your PC Desktop, You Will Then Have Eight Files On Your Desktop Which Will Be MODIFIED_TMO_SPR_N930PVPU1APH3_REV00_ENGBOOT_FIRMW ARE.tar.md5, graceqltetmo_N930TUVU1APGC_Stock_Deodexed.img, SAMSUNG_USB_Driver_for_Mobile_Phones_v1.5.45.0.exe , adb-setup-1.4.3.exe, CommandPrompt.bat, Odin3.exe, Odin3.ini, And sun7.
3. If You Haven't Setup ADB On Your PC Yet Or Installed The Samsung USB Drivers, Just Open Both Executables SAMSUNG_USB_Driver_for_Mobile_Phones_v1.5.45.0.exe And adb-setup-1.4.3.exe And Complete Both The Setup Processes. Once Done You Should Now Have A Created ADB Directory Which Should Be Located At C:\adb. Once ADB Is Setup, Place The sun7 Folder And CommandPrompt.bat Inside Your ADB Folder From The New Directory.
4. Now Put Your Phone Into Download Mode By Powering Off Your Device First And Then Hold The "Volume Down+Home+Power Buttons" At The Same Time Until You See The Download Mode Warning Screen. Now Press The "Volume Up Button" And Then Insert Your Samsung USB Plug.
5. Now Open Odin3.exe, Click On "AP", Select "MODIFIED_TMO_SPR_N930PVPU1APH3_REV00_ENGBOOT_ FIRM WARE.tar.md5", And Then Click On "Start". Wait For A Couple Of Minutes For The Modified N930PVPU1APH3 Engboot Firmware To Finish Installing. After this step it says failed so this is where I'm suck currently at the bootloader. thanks guys for your help

It still works its just stuck at the boot loader. I think when I attempted to flash the stock rom back on the phone It wiped everything. Honestly I'm not trying to root I'm just trying to install the stock rom
You should be able to download it in Sammobile, they usually have every firmware available for Samsung phones. Then you would want to checkout the N7A their accepting beta testers for v2 of the app. Maybe check with them before to see how you should proceed on reinstalling the initial firmware to avoid the update again.

No problem I've been using package disabler pro & N7A's shield for a while now and haven't had any issues. Plus N7A is a really great community especially when other forums don't provide much assistance. I think about 80% off the people still using the Note 7 have either joined N7A or the N7 Rebels (I've heard they charge for their app & assistance but haven't verified myself). ?

Ok cool I just signed in to N7A site. It looks really informative. I downloaded the firmware from sam mobile as you suggested also I have about 10 more minuits before its done downloading. ill keep you posted.
Ok I'd check the help and tutorials section for re-flashing firmware after an update, cause I'm not sure how you would avoid getting the update again unless you have a some sort of shield or package disabling app in place.

downloading the shield now. hopefully this works because I had to go back to using my note 3. and I'm like OMG what a major downgrade

Hey just giving you an update. Phone still stuck at boot loader but I have watched the lady known as catwoman video on youtube. I have downloaded and unzipped all the files and even tried to flash without success. Oden keeps giving me a fail. The only problem is with the smart switch application she recommended for download. I downloaded it and ran the app like suggested. It said that the my device is unsupported by smart switch. I cam to the conclusion that this is the way I should have started vs wiping everything which is the reason I'm stuck at the boot loader because there is no data on my phone. Here are the steps I took to get past this problem.
1. Reinstalled Smart Switch, but after the re- install no success.
2. I reopened Smart Switch and clicked the tab that says "MORE" then on Emergency Software & instillation. I followed the steps which included imputing my device model number and S/N. Did that but my device is still reading as a unsupported device on smart switch. I'm in progress of contacting her to see if she or any of her team as any ideas. Hopefully I'm back up and running soon. I cant wait for the note 8 so I can be done with this

unlocked, twrp'd & rooted... what now?

I'm not really sure what I'm doing, I changed my country code from "demo" to eu and I'm on EVA-L09C432B182. There's so many different versions and I don't know which is good or even compatible. What would be the next thing you guys would do in order to get the most from my phone?
Edit - I just jumped in at the deep end and everything wen't well, I'm now on Nougat with emui 5.0, if you're in the same boat as I was, I used the Huawei Update in the second post of this thread: https://forum.xda-developers.com/p9/help/p9-7-0-nougat-update-eva-lo9-b182-t3539754"]https://forum.xda-developers.com/p9/help/p9-7-0-nougat-update-eva-lo9-b182-t3539754

I have an eva-L09 with C900B190 and have country "demo" ??
I read a lot of posts how to get from the C900B190 to a Rom that has ota updates.
Before I start and because I am a bit of a noob I want to be absolutely sure I get all steps correct...please help me out and confirm/correct this
1) set develloper usb debugging
2) make sure phone connects to pc
3) install latest twrp
4) unlock boot loader with tool (https://forum.xda-developers.com/p9/development/huawei-p9-eva-l09-eva-l19-eva-l29-tool-t3591358)
5) make note of unlock code
6) use twrp to flash B136 (still have to find zip)
do I get ota to android 7 or I have to flash latest Rom meself (what is the best version for eva-L09?)
After that can I lock the boot loader and stay on android 7 or will the phone reset with locking and revert to android 6 again?
Thanks for helping
Contacted huawei, they were very helpful I will probably go to the service center to hopefully reset my phone to receive updates.
I also asked for an unlock code in case I need a plan B.

Seems I have no warranty (I got the phone from a friend and have no papers or anything) and have to pay for service centre. So I will try unlocking myself...

Xiaomi mi9 Vodafone Rom

Hi everyone!
So, I just bought myself a Xiaomi mi 9, and the phone itself is great. Still, I'm having a problem related to the ROM that's installed on my device.
When buying this phone, I was looking for a global version. I found one online from local shop, and I was pleased to find what I was looking for. But now after 2 weeks, I was searching the web about updates and MIUI 11. Soon after, I realized that my phone was running a ROM version called 10.2.18.0 PFAEUVF. Now from my understanding VF stands for Vodafone, a carrier I don't even have in my country. The problem with this is that from what I've been reading online, that all updates will be slower, and possibly tweaked from Vodafone before I get them. And frankly, I'm not interested in this at all.
So my questions: Can I put the correct EU or Global ROM on my device fairly easy?
Will I be able to lock bootloader again, so I can use bank related services after?
I'm not new to Android, but I would be extremely grateful if someone could help, or give me a detailed guide on the matter if it's possible to solve. English is not my native language, so it's not always that easy understanding how to-do guides when reading a ton of information.
Sorry for the long text, and if someone know anything about this, I will patiently wait for your reply
Sincerely
Fred

well, if you already have the bootloader unlocked and you are "carrier free" in that phone, you can flash the EEA ROM or the Global ROM from Xiaomi using MiFlashTools, download that and download the zip of the rom, need to be a fastboot ROM, its pretty easy to find since you are on MIUI10, there's lot of MIUI10 ROM for Mi9.
In the MiFlashTool in the bottom right see if they have the option "clean all and lock" or something like that, extract the zip of the ROM you downloaded and then search the folder in the MiFlashTool, click start (dont forget to put the phone in fastboot mode, phone off, press and hold volume up + power button) and thats it, pretty easy.

Im unlocking bootloader, waiting for timer to go down. So basically the most important thing to me, is that I I'm able to flash normal/global ROM without Vodafone and then lock bootloader again without damaging anything. I did not buy the phone through carrier, although the phone came with this Vodafone ROM sh...t
Vodafone is not a carrier in my country, so I've been using my local simcard without any problem, so I guess that a good thing.
@Fredoksi: how did it work out at what did you flash? An EU or a global ROM and do you get updates after the flash or do you need to install these yourself?

Hi @Sun_is_shining, I'm in the same situation. Unlocked my phone but got a Vodafone rom.
I see that you mention to activate the option "clean all and lock". Why should I do that? Isn't that going to lock the phone again?
I want to install Lineage 17.1 unoffical rom on my phone so what is the best way to go?
Other queistion. Currently I have a 10.2 MIUI. Is it best to install an 11.XX rom first and then the Lineage of can I go straight to the Lineage rom?
I'll hope you have some answers

It worked flawlessy for me. I went from vodafone (EUVF) to European (EUXM) and locked bootloader instantly when flashing. I also recommend after booting up the first time after flashing, to go to settings and do a factory reset first before you use it.
Installed 11.0.8.0 QFAEUXM and upgraded directly to MiUI 11. I get system apps updates, but due to Coronavirus I don't think they have newer firmware versions at the moment. Nevertheless, OTA should not be a problem when available.
Feel free to ask if you have any other questions.

Well, first of all I wanted to see if it was possible. If this was not the case, I would probably return it due to harder aftermarket sale. Secondly I didn't want the hassle when using things like Bank ID etc, and yes I know there is a lot of working mods and what not, but again if I sell the phone, the other person might not be into modding etc, so all in all a mix of ease of use and safety from my side.
Another Vodafone ROM...

Hi @Fredoski!
Thanks for your reply. Are you from Brazil? I"m from Rio.
I bought a Mi 9 yesterday and find the same situation.
Can you help me? I have some questions:
1- Where can I download the tools to do the flash operation? It's the same MiFlash used to unlock the device (miflash_unlock-en-3.5.1108.44.zip). Have long time ago I used to do this kind of thing on my smartphones. :silly:
2- If I understand well, you flash the MIUI 11 on top of the MIUI 10 Vodafone, is that corect? The ROMs on MIUI ROM page are "fastboot" ROMs? Could I use this to flash the smartphone?
3- Any others complains about? I can't brick my smartphone on the process!
I'm glad if you or others members could help me!
Thanks!
Done!
I already made the ROM flash to EEA ROM. Thanks!
Hi,
I wanted to ask how it is with the warranty.
Do I still have warranty if I go from the MIUI 11.0.10.0 (QJBEUVF) to the MIUI 12.0.1.0 (QJBEUXM).
I would be very thankful if I could get an answer.
Like you did it with MIUI 10 Vodafone to MIUI 11 Global EU
Hello,
I'm in Portugal and I bought a Mi Note 10 Lite carrier free but with a Vodafone Rom... Weird...
Can you please tell me steps to remove this Rom and install Miui 12 Global?
Thanks.
Best regards,
Pedro

V405UA vibration problem

Hello guys,
I bought new (open box) v40 on ebay and it stated V405UA unlocked. It came with Android 10 v30d.
All is working good except vibration. It doesn't vibrate at all. I tried factory reset, safe mode, application to test vibration and checking battery saver. And it doesn't work for notifications or keyboard feedback.
I contacted seller and he suggested i try to flash V40UA US android 9. I tried flashing V405UA020g_00_USC_US_OP_0424.kdz with LGUP from this forum and it showed me crossflash error (US>EU).
I then tried V405EBW android 10 V405EBW30d_00_OPEN_EU_DS_OP_1223.kdz and it showed me different crossflash error (jadypn_lao_eea>@judypn_la).
Can you please help me identify problem with vibration or recommend what file to flash, as I cannot find any EU V405UA fw.
Thanks in advance

whoa boy, what a mess. Well, how big of a mess depends on some unknown things, but there's potential there
First, you say u were on 30d. Which 30d? At&t? vzw? Euro version? There are a lot of 30d's.
Second, the version you were on u may not be able to get back to, if they were at&t or sprint, as they don't make thieir kdz available. No one has one, anywhere. What should have been done, if on one of those firmwares, was to use a special too (bkerler edl) to back up all your partitions first.
Third, the issues you're running into with crossflashing are pretty easily overcome. You just have to use the correct lg up version and matching dll. Also, to crossflash u have to do a partition d/l, none of the other options will work.
Fourth, vibration issue is almost certainly a hardware issue. Probably why it was an 'open box'. Personally, if that doesn't work when I buy it, I return it. It's unfortunate the seller told you to modify the phone, as that usually is the reason they will refuse a return, if it's been modified?
I'd guess the vibration thing is a hw issue, unfortunately.
So what firmware do you WANT to be on? 9 or 10? Which carrier do u use? U need firmware that has those bands. If u can't return and have to live with the no vibration, to me anyway, not end of world.
cheers
Hi,
Thanks for quick reply. I apologise for chaotic first post.
I was on european 30d, there was no further info in system menu i can recall sadly.
I solved issues with crossflashing and successfully flashed these firmwares:
V405UA21c_00_USC_US_OP_1028.kdz
V405EBW30d_00_OPEN_EU_DS_OP_1223.kdz
but none of them solved the issue. (first one recommended by seller, second to get back to european)
Seller offered me that I can return the phone and they will solve the issue, as there is 30 day return policy and 12 month warranty. They even would pay for shipping.
I am now considering returning the phone, but I have smart bracelet which I mainly use for notifications, so I do not depend on vibrations so much. And seller is half of europe apart.
The reason I was thinking that it was software issue was that I found on xda and elsewhere that android recoverry from google backup can be corrupted and then vibrations do not work and my previous phone Xiaomi Mi A2 Lite has occasional problems with vibrations, which is odd coincidence.
Phone was sold as open-box, but the phone itself was sealed. But i think seller flashed the firmware, because it is US version with EU fw and android 10 out of the box. Seller even helped me to get right version of LGUP.
My last question would be if there is a way to tell what causes the issue, if it is hardware.

Interesting, good that your seller sounds pretty responsible. Have never used android recovery from google backup, so no help there. The only thing I can thing of to help determine what the no vibration issue is, other than opening the phone, would be to use a logcat and see if there's any error info in it.
Start the logcat just before doing something that would cause the vibration to go on, then shut the logcat. Look for errors...
Additionally, as you've experienced one significant issue, fully check everything else; camera, flash, speakers, anything and everything hw related. that's what I'd do anyway.
cheers
Nothing else seems to be defective.

I'm no expert but from that output, seems to me the software thinks it did it's job. No indications of any problem, but it may be the software tell's it to 'vibrate' and whether it does or not, doesn't matter, as it may not have any checks for errors of any kind.
Additionally, it seems pretty unlikely LG is going to put out an OS version where something as common as the vibrate function doesn't work? Have not heard of any version doing that anyway.

Hello guys,
I bought new (open box) v40 on ebay and it stated V405UA unlocked. It came with Android 10 v30d.
All is working good except vibration. It doesn't vibrate at all. I tried factory reset, safe mode, application to test vibration and checking battery saver. And it doesn't work for notifications or keyboard feedback.
I contacted seller and he suggested i try to flash V40UA US android 9. I tried flashing V405UA020g_00_USC_US_OP_0424.kdz with LGUP from this forum and it showed me crossflash error (US>EU).
I then tried V405EBW android 10 V405EBW30d_00_OPEN_EU_DS_OP_1223.kdz and it showed me different crossflash error (jadypn_lao_eea>@judypn_la).
Can you please help me identify problem with vibration or recommend what file to flash, as I cannot find any EU V405UA fw.
Thanks in advanceI

Hi,
I have already solved flashing complications.
Do I need Dual Mode for flashing or for testing in "PHONESETTING"?

Question Phone bricked after unsuccessful OTA

Hi all, I just had the S23 for a couple of days now and have experienced quite a few bugs: Camara failed, restart automatically from time to time, cannot enter themes saying not available in my market (successfully logged in the next day).
Therefore I was quite happy when there is an OTA popped out today and I immediately started the OTA update.
However the update stuck at the download mode, error message on screen being "Build-id does not match with the reference".
Followed the instruction to restart, and try entering the recovery mode both did not work, all coming back to the download mode screen.
I've never flashed my device, any ways to clean the cache and do the OTA again? Just need to bypass the download mode screen...
Worst case is I return the phone to the original dealer (still within 14 days regret period) and get a new one. I just moved all my data to the phone and am quite reluctant to do so if there's no other alternatives.
Thanks for your help in advance!
I would return it. Not a good start... if it's hardware it will just bite you again, eventually.
A Samsung Experience center at a best buy can run advanced diagnostics on it and reflash it if you decide to play Samsung roulette.
The data is toast either way. Wishing you had an SD card slot yet?
Thanks for the

Thanks for replying. I try to do a online smart repair but obviously S23 is too new to be included in their aftersales tool. Here in Germany there is only limited places that I can go. So probably I end up returning it but it's such a pity since it has the best phone camera I've used and I really wish to stay...
You're welcome. Sorry. That's too much money to risk it being a hardware fault and even it isn't you shouldn't have to be reflashing it right out of the box. That takes away the joy of new ownership and then some.

That's bad luck indeed.
Either Samsung shop to fix that? Either returning it or asking for an exchange yep. For you data, didn't you sync on Samsung cloud or Google cloud?
Good luck with this sh*t.
Ps: idk if your computer detect your phone? So you could flash the firmware again through odin? I read this tool can detect the phone model and automatically download the latest firmware directly from Samsung update sevrer.. Idk what it worths https://forum.xda-developers.com/t/tool-frija-samsung-firmware-downloader-checker.3910594/
Ps2: funny when I mentioned frija and odin 2 guys from our cousin Ultra came
Odin it with the firmware from Sammobile or Frija - Relatively straight forward etc

Yes, you can very easily just reflash the firmware using a PC - and no factory reset required

Thanks for the tip. Used Odin and it did work. However when trying OTA it comes again, so had to flash once more. I'll just leave it and Samsung was kind enough to give me 5% on my next order in Samsung Shop so I'll just return this and get a new one via Samsung. Hope I'll get a normal one.

Are you downloading the right CSC maybe? Keep in mind Europe has 2... EUY and EUX...
Plus the new firmware is downloadable now BWAB I believe
