ISSUE! HELP! Unable To find custom/stock ROM/OS for OnePlus Nord N100 [BE2015] - OnePlus Nord N100 Questions & Answers

As my question dictates, I have erased my data partition through TWRP and currently unable to find a custom/stock ROM/OS. Details on how this happened is below.
I have done the following to my OnePlus Nord N100:
Unlocked the bootloader, Installed TWRP, then I got stuck. I discovered the reason why Magisk wouldn't install through TWRP; it is because I have already encrypted some partitions when enabling a pin/pattern/facial recognition. The only way to fully decrypt those partitions is to factory reset the phone and set it up without ANY lock configuration. Here is where I made my fatal mistake, I acted without checking if there was a stock/custom ROM/OS available to download and flash through fastboot. I was wrong. I deleted the "data" partition through TWRP and I have basically bricked my backup phone until I can find a ROM/OS that is fully compatible with my phone. ANY help would be much appreciated in helping me search for any ROM/OS suitable for the "OnePlus Nord N100".
Thank you in advance,

I hope you booted into twrp from fastboot and didn't flash it. If you have stock recovery you should try factory reset from there. Otherwise use one of the unbrick tools.

Don't know if you figured it out or not but you have to use the one plus recovery tool. It's been a year since I bricked mine similarly. I think I had to put it into emergency download mode and run the recovery software. I believe it's here on xda somewhere.

I sent links nine months ago in this thread to not only all versions of the stock ROM but also the unbricking tool mentioned; I dont know why everyone's pretending I don't exist.

Prevention for hard brick.

Hi, i like to know the prevention for Moto g5.so I can't able to brick my device again. thanks in advance
Don't flash recoveries, kernels or ROMs that are not suitable for your phone. However, in some cases mentioned above, phone will start. This is also related to other Android phones, not just Moto G5. An exception is if your device support Treble (Moto G5 does since today). Then, you can flash any ROM WITH TREBLE SUPPORT AND PARTITIONING CORESPONDING TO YOUR DEVICE - A ONLY or A/B.
Don't even try to flash stock firmware with older security patch than you have currently installed - everything except gpt and/or bootloader will flash because of preflash validations. Corrupted or missing gpt/bootloader will end up in hardbricked device.
Even, there's already a tutorial for fixing hardbricked G5 (by booting off from sdcard), it may, but also may not work for you. Always be careful of what you are flashing to avoid situations that are difficult to fix.

Thans for replying. If I flash the device without using gpt/or bootloader codes (in case of using old firmware).then my device will not get bricked.is it right.

It won't get hard bricked because you are not changing the boot partitions or bootloader so you will be able to access fastboot
Your phone may not boot (for example if a kernel requires a certain bootloader version) but it won't be hard bricked

Or for example if ROM needs certain kernel... still remember how much I was scared when I've softbricked my old Xperia X8 for the first time.

Thanks for help.
My piece of advice:
DON'T ATTEMPT TO DOWNGRADE USING FASTBOOT.
More specifically: don't flash gpt/bootloader files with fastboot. When you flash an older bootloader through Fastboot or RSD Lite, you end up with a brick and you will need a blankflash file or an image dump on a Micro SD card.
Just backup everything you can and be very cautious of what you flash, better safe than sorry.

MODEM went crazy after upgrading MIUI to [Global 10.3.5.0] from [China 9.6.12]

Hi, I'm begging you all for help.
Please, even if you don't know the answer, share any sort of advice.
I'm not a newbie (25+ years story of Unix/Reversing), but I know nothing about radio.
Here's a list of symptoms:
1) Sometimes the WIFI MAC Address comes up as 02:00:00:00:00:00 and IMEI isn't available, then they both magically come up (without rebooting, after the SIM Is read - see n. 2)
2) It keeps powering ON & OFF the SIM and switching between Connected , No Signal , Emergency. Sometimes taking the SIM out & back in helps. Selecting the Preferred Network Type from the modem debug screen keeps it connected for long periods.
3) It won't search for alternative networks to Register Manually
3) IMS Registration is showing as Not Registered always, even while it's connected: Voice + Data (?!?)
4) From the Debug Info only 1 cell appears as SRV = R+N and has a CELL ID, so it seems it connects only to 1 cell at a time.
I can't post screenshots as I lost my old username here, so I signed-up again.
Nothing works, it was a new phone. I wanna die.
Thank you all for your help.
Thanks.
I have problems with modem and camera wgen updating ta android 9.
I would recomend you to rollback to 10.2.1.0
I would use this method
1. Backup your media files to your computer
2. Unlock bootloader
3. Download fastboot china version of 10.2.1.0 and Flash it with mi flash (choose wipe but dont lock!)
4. Flash orange fox twrp with fastboot
5 wipe all partitions exvept internal storage with orangefox
6. Download 10.2.1.0 from xiaomi.eu and flash it with orangefox
Tell me is you want direct links to all files that you need.
If you still have problems after downgrading I can prove my persist and modem files
Good luck

@eliaztheone thank you for your reply and your offer about the files, I'll take it if necessary.
Just one question: won't that trigger Anti-Rollback ?
(I don't need to stay on MIUI: do I have other options?)

Your anti rollback is already triggered on 4. Thats the arb value on 10.2 too. As long as you dont flash older miui 9 firmware you should be ok...

The roll-back went well but the phone is still unstable.
I'm not sure why: did the Persist get corrupted? Or the EFS partition? I have some backups but I'm not sure what to do.
Can you provide the files that you mentioned, or maybe some pointers?
What could be wrong with the phone?
Thanks a lot @eliaztheone

I can give you my efs and persist backup if you want? Then you can use partitions backup and restorev from playstore.
You need to be rooted with magisk to restore
Are you on the xiaomi.eu version of 10.2.1.0 and is it the 8.1 version or 9.0?

I am on Xiaomi.eu 10.2 with Android 9 now, as you suggested. Rooted & with Magisk.
I have backups of my old PERSIST from the China 9.x ROM. Should I flash that (or do I risk bricking) ?
I was reading on persist.img and I don't understand one thing: if it's different for every phone, why there's a persist.img in every Fastboot ROM ?
EDIT: I flashed my old Persists (tried various ones), and the problem.....persists! :') lol
So I'm back to my most recent Persist and still in need for help.
PS: if it helps for a diagnosis, any time the modem resets the SIM it dumps a lot of logs in /ramdump

Sorry I was not clear with my guide.. You needed to flash the android 8.1 version of 10.2.1.0 . I guess that wont help either but maybe so try it..
Try it and if it does not work. I will make backup of my persist and efs and modem and send them to you and after that u need to change to your imei numbers with qualcom app..

I tried it following this guide to restore the Persist partition (https://forum.xda-developers.com/xi...guide-restoring-persist-partition-to-t3906424 - via Fastboot, not EDL) , and right after flashing the SIM was working fine on 4G/LTE and the phone didn't present any problems.
Then I opened up Google-Maps and gave it permission to read the GPS and it went crazy: not reading the SIM anymore, rebooting, etc. And turning GPS off now won't help. So I guess the problem is with the Modem and the fact that it connects to only 1 Cell - no idea why.

I am on 10.2.1.0 - Android 8.1 now. In addition to what you suggested I restored the persist.img via Fastboot (not EDL) following this guide on XDA .
Right after flashing the phone didn't present any problems (SIM/4G was working without hiccups). As I opened up Google-Maps and gave it permission to read the GPS it went crazy: not reading the SIM anymore, rebooting, etc. Turning GPS off now won't help, it constantly reboots - I have to use Airplane Mode.
So I guess the problem is still in the Modem. Maybe it's the fact that it connects to only 1 Cell, apparently.
@eliaztheone if you can provide the files I'll try one last time. Thank you.
I will upload them tonight hopefully. You need to be on 10.2.1.0 oreo xiaomi.eu version.
You also need to be rooted with magisk so you can restore them with partition backup and restore

Did you try to flash modem_fix_ysl.zip? It resets the modem.img and modemst1.img and modemst2.img
Take your time, thank you.
While inspecting the ramdump I noticed the following:
[ 21.864464] [c:1] [p:<003975, android.vending>] Fatal error on the modem.
[ 21.864522] [c:1] [p:<003975, android.vending>] modem subsystem failure reason: rflm_diag_error.cc:361:[email protected]_qlnk.cpp:1090 [9,3] RF stuck in QLINK start s.

There's many SELinux odd log entries too, not sure if that's normal. When I disabled SELinux from the terminal the 4G immediately picked up...totally weird

Thank you.
EDIT:
- I flashed modem_fix_ysl.zip but it didn't have any effect.
- I find the ramdumps from the china ROM much cleaner and errorless than the Xiaomi.eu ROM, just saying
I have sent you a pm
Have you guys found a solution? I have the exactly same problem on Mi Max 3 4/64Gb version. I'm on MIUI Global Stable 10.3.5.0. I was on China stable and had issues,so i flashed Global Stable fastboot rom using Mi Flash Tool(flash all option),and It doesn't solve the problem.I have unlocked bootloader,and no previous system backup.
Also i tried flashing NON-HLOS.bin file from Global Stable fastboot ROM using command : fastboot flash modem NON-HLOS.bin
Also i tried something that worked on my old redmi 4,after NON-HLOS.bin flash,executed fastboot commands :
fastboot erase modemst1 and modemst2,but no luck because of "partition is write protected" error.
Have you found what's the cause of this problem?Is it hardware?Is it corrupted modem files?Will custom rom solve it? Please, any help,any suggestion will be appreciated. I'll try everything to fix it. Thank you in advance.

I tried the following:
- reflashing Global ROM
- flashing Xiaomi.eu ROM as per instructions of of Eliaztheone
- restoring a backup of old China ROM
- reflashing China ROM
- analyzing the ramdumps (memory dumps & system/radio-modem logs)
- EDL flashing (with `fastboot oem edl` - not with the deep-flash cable)
All the reflashes included overwriting the EFS (modemst1/2) & PERSIST partitions, automatically (in bulk) or manually, taken from various sources including those that Eliaztheone kindly sent to me. The EDL flashing didn't work because I had no authorization on my Xiaomi account (I've tried all combinations of SDR programmers & old versions of MiFlash - none works) so I've then tried to get a remote authorization, also without success: the guy from UNBRICK.RU told me that Xiaomi revoked all authorizations lately to push out of business the remote-auth-flashers.
From my understanding of the ramdumps the problem seems to be an internal modem fault. Since ARB wasn't triggered when I rolled back to China ROM, I suspect that the fault is a hardware (or very low-level SW) software in the radio modem, and so it can be maybe fixed only by EDL flashing.
That's why I resorted to finding a local authorized service center this week. But I have to see how much money they ask me: if they ask too much I might as well buy a new OPPO or REALME phone, which are cheap & open (at least more than ****ty Xiaomi). If the service center pisses me off you'll see the result in the news.
Support the right to repair movement.
I hope this helps.

Thank you man, I'll try everything you said tommorow. The device hardware is awesome,and i really want to support xiaomi,only if they had solution for this problem. Also i think keeping ARB on unlocked bootloader is a bad decision,it really makes this whole process harder.
I'm hoping you get you phone fixed and looking forward to see how this will end.
Thanks for helping me man.

All authorizations has been locked down for a while now, learned that the hard way during in the early days of ARB4 and i tried to flash a stable rom with a lower ARB number and my phone bricked. IThen i found someone to flash a beta rom by remote with authroization; costed me 15 USD. EDL flash was the only way if you still have fastboot. I worked with the service guy because he also wants to figure out the problem also. After bricking my device 4 times, I got the right recovery to use and then TWRP Recovery worked for the 4GB version. I got the 6GB version also and the people who sold me the phone had already unlocked the bootloader, I had to double check to see using command prompt. The i flashed the Recovery i was given to by a user on the AOSiP thread, thinks its Page 7, its a TWRP CN Recovery.. and it worked in both devices.
@Wmateria can you give me the contact of this person who gave you the remote Auth ?
I just phoned Xiaomi and they told me that Xiaomi's warranty is only valid at national level (read: each european country collects phones sold on its territory, and sends them to specific labs).

(HELP!!!) Accidentaly Locked Boot Loader on wiped and bricked phone

Hello,
The Xiaomi 9 SE Global Unlocked of my girlfriend was restarting a lot (restart loop) and I tried to flash a ROM but I accidentaly flashed and locked the mobile on a "MIUI version that can´t be installed on this device" (grus_global_images_V12.0.2.0.QFBMIXM_20200910.0000.00_10.0_global)
The problem is the phone was wiped and I cant unlock the phone now. What to do? I can´t flash another ROM or unlock it and I just have access to Recovery Mode and Fastboot mode.
Please any help would be greatly appreciated.
It´s 4 am where I live and I´ll go to bed... But Will read here as soon as I´m awake. Thanks a lot in advance.
Let me continue my story... I still need help.
I contacted an authorized and he helped me to EDL a flashed version and I reinstalled the MIUI 12.0.2 Global stable on the phone.
But the phone is still TURNING OFF BY ITSELF (this was the reason because I tried flashing it on the first place). I don´t know the cause but it does not seems to be a faulty battery. I heard the phone has Anti RollBack protection. Is it right?
So I need help on how to procced. I would like to RollBack it to MIUI 11 where I didn´t had this problems...
Unfortunately you can NEVER go back once you flash a ROM on Xiaomi devices. However that doesn't prevent you from flashing custom ROMs.
Though you still need to be careful, because once flashed there is no going back.
I recommend testing the ROM on an emulator before flashing it. Here is how.
Also don't forget to check for your rollback protection index and the ROM's index before flashing.
Follow this post and scroll down to "How to find rollback index of images".

Question [Question] Who has rooted TMOBILE 9Pro Stock ROM

I understand I can convert to EU.... However, I don't wish to do that. I just want to root my stock TMOBILE ROM.
My sim is unlocked and I have the unlock.bin from OnePlus for my phone. For anyone who has rooted TMOBILE stock ROM, which boot.img did you patch? I've read that AA boot image can work, but no firsthand accounts confirming this.
Ideally, I'd like to use my own boot.img but I can't find a tutorial or guide anywhere advising how to obtain my boot.img without root.
Thanks!
use AA boot img, but recommend unlocking Bootloader and backing up your tmo modem a/b imgs

Use partitions backup (app) to backup the existing TMO Firmware first and copy your files to a pc before you do anything. As with any flashing you run the risk of wiping your info and stored files..

What is partition magic? An app? Software?

Sorry meant to say partitions backup. Which is an app.

Thank you... unfortunately partition backup requires root. So I can't back anything up until I unlock and root....which using the AA boot image to root kinda freaks me out

It is understandable to be freaked out,. But if you follow the direction letter for letter then you should be fine.
Also good rule of thumb is make sure you have all the drivers and software loaded on your pc, then make sure your pc and phone can talk in adb and fastboot before you start to flash your phone.
I have rooted my stock tmo rom with aa and all good. Of course I went even further and installed the EU version on my tmo bought 9Pro..

Yep, confirmed, 9pro and my computer can talk. The whole MSM thing is what is worrying me. In the MSM tool, it says it is the TMO -EU MSM. So, once it does it's thing and flashes it all, it should wipe the phone, it would be on the EU rom?
From there, I would need to follow the steps, unlock BL, flash modems, and then download oxygen updater to be able to locally download updates and install?

Question No OS and no TWRP = Please Help

Hi.
I am new to Custom Roms and therefore have absolutely inadequate experience, so I would be very happy to receive help.
(It's a Poco F3 [Alioth]+Bootloader is Unlocked)
Currently neither an operating system nor TWRP is "installed".
I have already tried to load the .img from TWRP onto the mobile phone while it is in the state where I entered the command fastboot boot twrp-3.6.0_11-0-alioth.img in the Platform Tools (cmd) (i.e. in Twrp only it is not installed?) And you can activate MTP under "Mount" (file transfer?). Only that doesn't work (mobile phone is only displayed on the PC when I want to drag files to it, it loads forever. (Mobile phone also has no SD card slot.
But how am I supposed to install TWRP without getting the file on the phone and with it Magisk and a Custom Rom?
Help is very much appreciated.
