where to find Bootloader 19s,20s,21s for north america? - LeEco Le 2 Guides, News, & Discussion

I have a X522 which is running lineageOS 14.1. I tried a few Oreo ROMS and I am tempted to try a few Pie based ROMS. However, when I tried those I had terrible GPS problems. I was running 21s bootloader and saw that a few people recommended loading 19s but I could only find a 19s for india. Is there a 19S bootloader that can be used in north america?
Can anyone explain or direct me in the right direction?
Thanks!

Stock Oreo firmware (fastboot) needed for XT1686 (retin channel)

I need the stock Oreo firmware for Moto G5 Plus Indian variant (XT1686) to relock the bootloader.
I know that the Nougat stock firmwares were different for different variants of potter.
But I read from a post that this is not the case for stock Oreo firmware and it's same for all variants. Is it a fact?
If yes then I have no problem as there are links available for fastboot version of stock Oreo firmware.
But if no then please tell me where to download the specific one for XT1686.
Reply at your earliest convenience.
Model is not needed, original software channel (Country specific) is required.
So if you can give that info, someone can point you in the right direction.

I found it myself.
The link is : https://drive.google.com/uc?id=1zE8nSFXhMaBbj9oAmEnypBh7_nRyHg6x&export=download
This firmware can be used for any channel as starting from Oreo Moto doesn't create different firmwares for different channels.

EEA 10.3.30 to 10.3.2.0 = anti rollback brick?

Hello.
Hope you can help because I'm kinda confused atm
My device is redmi note 7 lavender, came stock with EEA (european global) rom.
I recently unlocked the bootloader, installed twrp, tried a few roms (xiaomi.eu, crdroid, phh-treble gsi, etc). Currently using crdroid without issues.
Previous to all this I was using stock EEA 10.3.2.0 firmware and then sideloaded ota for 10.3.3.0.
According to this post this phone has ARB
What I'm wondering is if I were to go back to stock firmware, would I brick my device? Because the only available fastboot version for EEA is 10.3.2.0 which is older I guess, but I'm not sure exactly how ARB works and it that would trigger it.
Thanks in advance
I recommend that you do not return to the previous version, sometimes the ota bring changes in the bootloader, and you can leave it hardbrick as it happened with several Motorola, even with devices that have a Qualcom processor. Expect that someone else has done it or that the software is released to an equal version.
start to investigate the changes that were added
I leave this link you fence to interest move from the EEA to the global version

If you're asking specifically about turning back from 10.3.3 to 10.3.2, then there is no problem (I went from 10.3.3 to 10.3.2 to 10.3.3 again and everything is ok).

My RN7 is global, came with 10.2.3.0 as stock, I updated via OTA to 10.3.5.0, and I was wondering if I try rolling back to 10.2.7.0 (As I didn't find any rom of 10.2.3.0 for global PFGMIXM) it will trigger the ARB? thanks in advance (both have lvl 4 in adb query)

Sorry to bother but, did you bricked going from which-to-rom, using TWRP or the mi-flashtool?

Rolling back firmware only through twrp, trying to get previous drivers for international version which bug less on proximity sensor.
As the phone is unlocked I might have found a way to restore from brick without physically opening the phone. Will keep you updated.
Edit/Update: yipeee!!
Need to completely flash the phone based on the procedure detailed here. And reflash whatever custom ROM afterwards as you get back to stock.
Just rolled back from Global 10.3.5.0 to 10.2.7.0 with MI Flash Tool (fastboot rom type). 0 problems, seems you can rollback from your MIUI 10 ROMS of the same version(EEA with EEA, Global with Global, etc, and of course that these roms have same ARB 4), at least worked for me, posting this future records.
Actually firmware tool (as opposed to twrp) is the way I reset ARB.

Change ROM from China to Global

Hello,
I just got a Redmi Note 7 Chinese variant but I live in India and the Chinese MIUI isn't that great. I want to change it to the global ROM. I have the fastboot ROM downloaded and even the recovery ROM. I'm hoping that someone has already addressed the issue but I'm posting this because I'm not able to find any. My phone is currently running MIUI China 10.2.13 and it has received the 10.3.4 update. I haven't updated it since it might increment the arb index. Can anyone give me a confirmed, safe and working method to change my software from China to Global? I understand the risks of bootloader unlocking and all.

Samsung T580 downgrade android Q to nougat or pie?

Hello, my tablet was a UK version with Chinese firmware (latest 2021) I tried to return it to BTU without suceess. It wouldn't let me flash other firmware after this except TWRP somehow but with a special app that unlocked the bootloader option.
The only Rom it would accept after flashing twrp was lineage 18.1 (I wanted arm64).
Now I have a bunch of apps that don't work with lineage 18.1 (boat beacon and AIS apps) and I would like to go back to a nougat, oreo or pie firmware.
I know there are some restrictions with sofware rev check etcetera when trying to downgrade from a later modem.
Is there a way round it??
Thanks in advance

LeEco Le Pro3 Update.zip for 19s American model

Hey guys, I am trying to install a custom rom on my LePro 3, however, every method I tried on this website and other websites for flashing LineageOS does not work at all. Eventually, I came across a post saying that my current version, 21s, does not support unocking the bootloader or something like that. It also said to have 19s installed on the device. There is a post on this site for the link download, except it doesn't work. I would really appreciate if anyone gave a link for the 19s stock rom.
