Question LE2120 IN Version - OnePlus 9 Pro

So I bought a oneplus 9 pro from a dude yesterday for 500 bucks which is an absolute steal. I unfortunately however have the Indian version of the software (Oxygen OS 11.2.10.10.LE15DA)(Model: LE2120) so none of my 5g bands are working, which is the main reason I upgraded.
1.) Yes I know there's a very popular forum about how to flash the global version of oxygenOS but the thread gets posted in and updated constantly with different info from different people so it's harder to follow.
I need the following:
1.) Previous IN Oxygen build to downgrade.
2.) Current Global OxygenOS Version to upgrade.
I know doing this can wipe your data but the phone is a day old so I don't have any data. I can easily switch IMEI numbers through TMobile app as well so I'm not worried about that changing if it does. I just want the correct versions of the ROMS so I don't up/downgrade to the wrong versions and critically mess it up. Any help is appreciated and thank you!

If I'm incorrect with any of the information I provided please correct me as well. I truly appreciate any information on this topic!

Can you post your phone info, I got my from clicking on settings>about phone
I know you already mentioned it in the text, but a picture would help.

Flashing a global/europe firmware wont fix your 5G. You need to do some extra step and need to be rooted to get the 5G back. And 2120 it's Chinese version which comes with Color OS as primary but sellers found a way to flash Indian firmware there and flashed and sold the phone.
Below you will find LE15DA Indian downgrade to 11.2.5.5 link: https://oxygenos.oneplus.net/OnePlu...110_all_2107082121_downgrade_66a1f653e8ee4eb5
Downgrade to this and then install European firmware but wont get back 5G anyway try.

PS: As you all know,Chinese offical limits my network to connecting XDA, so I coundn't answer your question immediately. What more, all of my full odin packages are downloaded at http://romup.com/ ,but it is not for free. Everybody can search ROMs by phone model in the searching box(with VPN to China).
The method can consult http://forum.xda-developers.com/att.../n920a-mm-odin-package-n920aucu2bpe6-t3415938 , Odin up on 3.12.4. And this firmwork don't Contain Pit files. Just flash first four files and waiting five minutes...

Hi, can i update from an unlocked AT&T N920AUCU2APB2 directly to this using Odin? Will that cause any issues?
hey guys, not trying to hijack the thread but i have a USCellular Note 5 which is unlocked and everything works but MMS and 4G is flakey, usually bouncing between 4G and H and H+ (on the signal)
i dont feel data speeds suffer but speed tests show it so fear signal reception could be different that an AT&T note 5.
anyways, does anyone know if it is possible to odin flash this rom into my USCellular phone and make it run properly on AT&T.
the NOTE 5 is of course unlocked and when looked at the specs is only missing 2 cellular bands and has more bands in 3G than the AT&T variant.
anyone have a clue, i would not like to brick this phone beyond repair but am willing to flash it with an AT&T rom if that will fix it.
the APN's area ll correct, but i did install KIK messaging and when setting MMS to manual APN it immediately came up with a uscellular APN which really makes me believe somewhere in the phone its still holding a USCellular APN and not using the AT&T one even though it is set in the Network settings of the phone.

Upgrade from old version of PureFusion?

Hi there, everyone.
I have a big or small problem. I want to be able to flash the newest Lineage or pixel experience, but I'm not sure how to upgrade the firmware. Below, you can see the version of PureFusion. I searched the forums and it sees that i need to upgrade the firmware first as i'm on the old nougat one.
The problem comes now, my phone is UNLOCKED, but S-ON and the CID is HTC_034 Europe. I'm not sure what method to use to upgrade the firmware, as it's a bit vague. For some CID you can't find the files, or other stuff. Can someone help me with some information in this case?

Totally wrong, the current purefusion rom has nothing to do with upgrading your firmware. You need to enter download mode, look at your OS number and search for the ruu that matches that number. Flash it, update and flash TWRP, than the desired rom. Whatever purefusion is showing is not what you need

AXE-LX2 on EMUI9, possible to unlock bootloader ?

Hello,
I'm talking to the XDA community that I've been following for quite some time in research to find a way to unlock my bootloader.
So I've already browsed pages and pages, and I've already seen the different techniques proposed here, but I have a difference that most users seem to lack.
I have a Huawei P20 Lite AXE-LX2 phone, while the majority of people here seem to have an LX1. It is of Chinese origin, under its name Nova E3. It is currently in version EMUI 9.1.0.353(C636E4R1P5) with a security patch of July 2020.
Coming back to the bootloader, I want to unlock it by the Telegram channel or DC-Unlocker, so I need to dowgrade to an specific EMUI 8 version.
Except that I already have the EMUI 8 stocks for my device, but none for EMUI 9. On androidhost.ru, I only found an EMUI 9 archive for AXE-LX2 (https://androidhost.ru/2CNs) by a guy who runs a site called ministryofsolutions.com . By downloading it, the content is protected by a password. So I sent an email to the guy, who told me that the archive was private and not for the public, so I'll never get the password (he runs a real small business in his country).
So I'm blocked at the first step because I don't have any EMUI 9 stock for my AXE-LX2. androidhost.ru only has stocks for AXE-LX1, so those on LX2 or LX3 are literally blocked.
When I tried other sites to find firmwares, I find myself with an archive full of drivers and softwares to install, not at all in the form of the dload folder to put on an SD card.
I also found this old XDA post: https://forum.xda-developers.com/t/ane-lx2-9-1-0-133-c605.3944407/ , but the same, not as a stock to install from an SD card, so I don't know how to do that at all (I put in screenshot the content of the two archives of the post).

Should I take the risk to install a stock AXE-LX1? Or could someone please give me an EMUI 9 stock corresponding to my model?
Thank you
I specify that I must first downgrade to an older version of EMUI 9 because HiSuite, whether in Chinese or English version, does not offer me the possibility to downgrade with my current version.

Hi, don't try it, it may brick your phone.
Unfortunately, there's no way to download Service ROM free for your build number, only for 17euros on paid websites.
After several hours of research, I managed to find a free stock ROM for AXE-LX2 at this address :
https://androidfilehost.com/?fid=4349826312261804346
The installation was perfect, and I found myself with an old version of EMUI 9.1 of at least two years old I think. Unfortunately, HiSuite, Chinese version or not, didn't offer me to downgrade my version, probably still too recent, or I arrived too late. If someone has another solution to propose me, please let me know in reply.
In case the file is down, I can upload it to another service.
Otherwise to get AXE-LX2 EMUI 8 stocks, there are two of them I know of for free on androidhost.ru.

Where is it reporting as SD1A.210817.015.A4? In Settings/About? Any other details such as what country you're in and what carrier you're using? Anything else you can tell us - are you rooted or applied OTA or factory image manually?

Are you using a custom kernel?
Can you check the hash of the full .017 firmware zip you downloaded and compare it to the hash shown on the website? (I check it after every time I download a full image zip, or an OTA zip)
minus case insens they match
BF3DA4B26554D84F99EAAD9837330C7D757F7D31442397EF89A98307D169D96A
bf3da4b26554d84f99eaad9837330c7d757f7d31442397ef89a98307d169d96a
no custom kernel
curious to know which is the one to apply for google FI or t-mobile or ATT (you'd think i'd know this working for TMO

It was always my impression to use the one that makes sense for the region and carrier you use, i.e. US Carrier, but at least one knowledgeable person in the P6P section said the A1 is the correct one. I haven't had problems with the US Carrier one on AT&T (.017). My wife's phone isn't rooted and she hasn't gotten the December OTA. I mainly leave well enough alone on her phones since some things I've done on all her old phones (which is always the same phone as what I have, to make it easier for me to give her tech support) have given her unwanted surprises.
Oh yeah - you could always try the Official Google Android Flash Tool and see if you get any different results.
so is the 16.a1 correct or 17 for us carriers?

I don't have any better answer than my reply #12. Since the .017 says "US Carriers" on the page with the list of firmware, that's the one I use.

Question ROM flashing in TMO LE2127

Hello guys, I just got this phone upgrading from my OP5T and I used to flash roms and kernels with TWRP, I see things have changed and I would not like to destroy my phone. I have always liked

trying new roms and messing with my phone, would really like to be able to flash Nameless or PE. I have seen that if you get the TMobile variant things get a little tricky with firmwares and phone versions. I got my SIM unlocked and I already have my unlock file to unlock my bootloader. Havent done that because I dont really know if my ROM flash would work.
Do I need to unlock my bootloader?
Can I already flash my ROM files directly from adb or do I need to convert my phone to EU with TSM?
I have seen that people mess with modules that I need to backup, is this only needeed to convert to EU version or would I need this for Nameless
?
Do I flash firmwares via fastboot/adb or do they come with local updates? Which I do not have because of TMO.
I have already asked a couple questions in the forum but I need to clarify myself with ROM flashing and prerequerisites with my 2127 version. I would really appreciate some help about this, Ive never tried getting help from forums and looks like this phone community is pretty active.
Go to the Nameless thread and follow the instructions to the letter and you will be fine!

Is it really that easy? I do not have to do anything else before because of TMO?

No, just make sure you follow every step in sequence. Read the instructions a couple times to make sure you fully understand everything. Like are you suppose to be on Android 11 or 12 as an example.
