Due to quite a bit of research, I now have faith in the rebranding method. I'd like to share the method and knowledge for rebranding with the XDA community.
Currently Available Rebrandings:
For Mate 9:
MHA-L29C432 (Dual sim, European version)
MHA-L29C10 (Dual sim, Russian version)
MHA-L09C432 (Single sim, European version)
MHA-AL00C00 (Dual sim, Chinese version)
For Mate 9 Pro:
LON-L29C636 (Mate 9 Pro, Int'l Version, Asia)
LON-L29C432 (Mate 9 Pro, Europe Version)
LON-AL00C00 (Chinese version)
Requirements:
1. (VERY IMPORTANT!!)THE DNS ON YOUR ROUTER MUST BE SET TO 37.114.61.203 -- Make sure this is done and it works before proceeding.MOD EDIT:Link to paid service removed If you can not set your DNS server on your wifi router, you might not be able to recover your phone. Changing windows DNS settings will not help!. The setting must be done on your wifi router. Consider this your warning!
2. External storage (SD card or USB OTG for Mate 9, and USB OTG for Mate 9 Pro)
3. Bootloader code
4. Ability to install TWRP (Check the TWRP thread)
5. MOD EDIT:Link to paid service removed A way to flash firmware to Mate 9.
(NOTE: The partition table is different between versions, and MOD EDIT: Link to paid service removed is the only method I know of right now that can handle changing those. If you use another method and brick your phone, please don't blame me.)
Steps:
0. Before starting, do a full factory reset from the Settings, Advanced Settings menu.
1. Unlock your bootloader, and install TWRP. For instructions doing this, check the TWRP thread.
2. With your external storage inserted into your phone, enter TWRP by holding Volume Up key without USB cable attached to your computer.
3. Once in TWRP, go to the backup menu, and make a backup of your oeminfo partition.
4. Turn off your phone.
5. Put the SD card or USB drive into your computer, look in the TWRP folder, and find the oeminfo backup.
6. Replace the files in the backup with the same files from the download link below for the version you want to rebrand to. Keep your original files somewhere safe so you can go back if you need to.
7. Put the SD card or USB drive back into the phone, boot back into TWRP, then restore the oeminfo partition you just modified.
8. REMOVED flash the firmware that matches the model you rebranded to. REMOVED
9. After the flash has finished, boot into recovery by holding volume up key. Choose the second option to wipe data/factory restore, then choose the third option to wipe cache. Your phone will now boot.
IF YOU HAVE TROUBLE AFTER FLASHING (Wrong version number, no OTA update in the menu, etc.):
1. Perform a factory reset from the setting menu, then do eRecovery again.
2. Ensure that you chose a compatible firmware.
NOTE:
It is very likely you will have trouble after the first flash. You will most likely need to flash TWICE with eRecovery.
oeminfo links:
Thank you for your help.
I've done the conversion almost as you sad but I encounter some problems.
So I started from MHA-AL00C00 and wanted to have MHA-L29C432
1. I've installed TWRP and backup-ed/ restored the oeminfo from your download link.
2. After the oeminfo restore and reboot the phone was in a booting loop - I could't get into TWRP anymore- I could only go into fastboot or into eRecovery.
3. As I didn't have the posibility to get access to modify the DNS on router (I was not home) I flashed MHA-L29C432B138 using HiSuite method.
After succsfully flashed I still have the normal bugs like directly flashing the EU software - Themes do not work, wallpaper changes to default, no Update, etc...
Right now on the phones it shoes :
Model Number : MHA-L29
Build number : NRD90M test-keys
Can you give some advice how I can rebrand it so it is full functional on EU software ? Is the eRecovery the only method I should use ?
Thanks

Hello.
To clarify, do you mean that you put the phone in fastboot and used HiSuite?
If it's possible, you should use eRecovery. I know that fastboot+HiSuite will not work correctly for rebranding (it will have the side effects you mentioned) but you might be able to try booting the phone, then using HiSuite update function.
But the way which is most successful is eRecovery. This goes for flashing regular updates as well. HiSuite is more convenient, but eRecovery is more reliable.

HI,
I put the phone in fastboot and used HiSUite to flash with funkyHuawei..
One more question : Now after the update when i put the phone in fastboot it shows as Phone Locked/ FRP unloked - is it normal ? SHould I do the enire procedure from the start to unlock the bootloader--> TWRP-->oeminfo--> reflash with FunkyHuawei or just reflash? to get the official update doesn't work neither from normal login or from fastboot.
Thanks

You don't need to touch TWRP again. Just use eRecovery method, and it should work. HiSuite/fastboot is only good for recovering a previous version, not good for flashing a new version.
Any luck getting oeminfo and/or firmware for the US version?

oeminfo is fine, I can make it for any version. But firmware is not available yet.
Updated to add LON-AL00 support.
Hi, I've just rebranded my Mate 9 Pro, everything seems good, but the build number shows NRD90M test-keys. Is there a way to correct this? Thank you!

Use erecovery to install the correct firmware.
Is it possible to rebrand from MHA-AL00 to MHA-L29C636, or MHA-L29C900. I'm living in China, and would like to receive OTA updates, I do have a SIM card from the Philippines. Thanks
Just to confirm , if you use HiSuite you will not get OTA and themes,etc just like reflashing without changing oeminfo. If you use eRecovery everything goes as intended. I haven't try to flash the firmware with Two or other similar. I just used funkyhuawei for both methods.
I wanna rebrand a phone (Chinese to International) but the monthly payment seems to me ridiculous, once I rebrand it I don't see the need to use the service anymore, it should be a one time payment.

I've tried the eRecovery again. But gave me error msg of: Getting package info failed. And the bootloader didn't relock itself.
Does someone has them please PM me I will give you credit$ because I'm in dead end with unusable anymore ls997 device.
I have lost my backup (pre-santa pre-rooting pre-custom roms) it was on my sd card which I formated after a while not thinking.
later I did other mistakes: on my dirty santa rooted ls997 I flashed LS997-deODEXd-signed. All fine but than because in software info it said US996 (yes because of the bootloader) I went for stock us996 10f .kdz using uppercut which didn't stop me because it recognised the device as us996. us996 .kdz rom removed root and twrp, all was fine except I got no service (all type of networks). phone recognises the sim card, but that's that no more (even manual setting the apns and manual choosing the network(can't be retrieved) even 112 and 911 won't work. Than I went re-rooted and re-flashed LS997-deODEXd-signed again, but my service was gone there as well (previously okey). tried other ls997 custom roms, in all of them service was gone. I guess I can fix that with twrp recovory of original stock backup files (mine I deleted by acc). I will give credits to anyone helps me.
You probably need to flash the radio from Sprint using dd
Go here for modem https://forum.xda-developers.com/showthread.php?t=3548454

I will try it today and report back thank you fellow.
I flashed (wrong) modem.img via twrp->install successfully. Big mistake as I ended up stuck in (attached photo) green screen after lg logo. Twrp still works, also adb still works when I hit volume down + plug the type-c cable in. Tried fastboot erase system than fastboot flash recovory twrp.img than from twrp flashed 1)twrp flashed other custom rom-no success(green screen still there after flash->reboot->lg logo) 2)flashed twrp backup I created the other day (only boot & system were ticked when I created the backup, they are from working status with custom LS997-deODEXd-signed as it is the same rom on my 2nd working v20) - 2) also went not successfull
3) opened uppercut on my pc but it recognises my device's port but version is uknown therefor can't use uppercut(it won't start because unkown version, pre-issues it worked, also on my 2nd v20 works but I suppose rom must be ok and booted in order uppercut to starts and gets the version of device).
4) I'm stuck. Can I somehow use my 2nd v20 (rooted, twrp ok, custom romed LS997-deODEXd-signed (old one from december),all software and hardware works perfect(including radio I do have signal bars data etc.) to fix my green screen on 1st v20 so if I fix it I can proceed with your instructions for the sprint radio via dd
If you did flash radio then i would try to flash the radio but i have never seen the green screen

If your device has a kdz, you can extract everything from it and flash accordingly. Or I think there is a fix for the unknown thing. My device does it as well.. There are dll files you need to get it to work.

He dosnt have a sprint kdz. Im asusimg hes talking the us996 kdz. Why you would have hit the sprint ls997 with the us996 kdz is unknown to me.. The sprint kdz is not avalible and the version that was leaked isnt in circulation and is encrypted.
---------- Post added at 01:11 PM ---------- Previous post was at 12:59 PM ----------
Im assuming you'll need more then just system and boot.img
The kdz i assume replaced your custom aboot. And the radio and modems all got swapped with us996 the unlocked version i hope and not tmobile variant.
I have full backups but parts contain things like ur esn imei and cant be shared.. Need more info on what is what. The green sceen is a big issue. Thats aboot crash
Maybe you lost the phone's EFS/IMEI file folder, Did you check that?

yes I used us996 .kdz. Im willing to do it again in order to undo the green screen and unbrick my phone.
your words seems legit yes I assume the us996 replacaed radio and modems that's why I got no service. BUT all else was working, no green screen. AFter that I flashed h918 modem.img using twrp->install->choosed modem.img->swipe to install. Only than I got stuck with the green screen and no re-flash helped. Tried twrp restore with 5gb backup fom us995 nrd90m stockimage (system,boot,chace) with no result - again green screen after lg logo.
If I can get uppercut/lgup reading my phone version again (with dd command and changing dll) I will swap back us996 kdz which was fine (than re-root re-flash twrp and custom rom - all back to square 1). us996 kdz is fine it did not make the green screen, booting h918 modem.img after that through twrp did it. us996 kdz only swapped my radio and modem therefor got no service but that's it no more harm.
I was in the US only temporary, now Im in europe using my tmobile(usa) on roaming(not for long I don't need my us number anymore) and european sim card on my 2nd v20. Therefor I don't really care anymore for my ESNs

Well, i think you have to check on Settings> About phone> Status and here it shows the phone's imei number, if you only see "000000000000000" then your phone does not have the EFS folder, then you have to fix that....

I checked, it's fine, imei is ok - the actual and full one
Update: I'm considering buying another clean ls997 sprint v20 since mine are both rooted etc. My Q is how can I extract the .kdz from the new clean sprint v20 unit ? (As I noted even with full twrp backup images the green screen is not fixed it's deeper issue maybe .kdz will fix it hopefully). I don't mind sharing the sprint .kdz afterwards since I will not use the phone in the US anymore anyways.
The kdz has to be leaked from Sprint....The only one that got leaked wss encrypted and we can't use it...the only way to get it flashed to stock is at a Sprint store unfortunately...it sucks

Lol... As you learned, cross flashing radios is a great way to brick. Also, never flash a radio through DD unless you are 10000% sure you know what every part of what you are doing does, and how it works.
Here is your problem. Your baseband (radio) partition is supposed to be a certain size... However, upon flashing a wrong image, with a low-level tool (DD), the partition is now corrupt and/or mis-sized. That means that another partition is overlapped by radio, or a part of radio is overlapped by another partition.
If you somehow get a KDZ to flash, it may or may not fix it.
The only way to fix this, would be with a very low-level tool, to manually repartition everything in pristine condition. If KDZ does that, then great. If not, then there is really not much you can do.

I'm trying my best to get the KDZ to flash, but it won't let me. Download mode on thehpne successfull, from there on - not.
Please recommend me some workshop where they can fix this green screen and get me going. It's sprint bad esn lg v20 should I contact Sprint and tell them I rooted and soft bricked and can they get me back to stock and charge me for this service that's fine ofcourse ? I can ship it asap since now it's just 350$ piece of shiny plastic in a box.

i get the impression that you didnt actually read the OP's post.
he has a kernel panic, and is unable to get his phone to boot android. the green screen in the very first post indicates as such.
in a small nutshell, OP flashed a file to a place that it should not have been flashed to. most likely, OP has given him/her self a really expensive doorstop.
unfortunate, but a lesson can be learned here. expensive and avoidable, unfortunately.

Most people have searched and found the modem files. They are mentioned in many of the ROM threads.

Sorry, but you are not very clear on your issue. A modem file will not prevent you from booting.
If you flashed B19, which I believe is for the A2017U, did you also flash a universal bootloader? I believe this will be necessary. Also, how did you flash it?
You'll need to say what exactly your phone is (A2017, A2017U, A2017G), confirm your booltoader was unlocked already (I suppose it was), what state you phone is in now, and what you flashed already.
Then perhaps someone who understands your situation can help you.

You'll need to say what exactly your phone is (A2017, A2017U, A2017G), confirm your booltoader was unlocked already (I suppose it was), what state you phone is in now, and what you flashed already.
Then perhaps someone who understands your situation can help you.

I bought it in banggood it's a 2017 4gb 128gb Chinese version, so I unlocked the bootloader, until then everything ok, I used the B19 \ A2017U_B19-NOUGAT_FULL_EDL miflash, this was the version I used to change the system from A2017 to A2017U. because when I start the system everything works well unless the area goes up, even with the chip says in the service, however I saw that it can solve this being and the Chinese and American networks are different. I installed the one that you sent me the link by twrp modem A2017 but when I start the system it is in the black screen of the message of the unlocked bootloader. hence I come back in TWRP and it works less the system starts

Sorry, but it is still not clear to me. It is best to wait for someone like @Choose an username... to help, if he has the time.
Flash this ch modem through twrp https://androidfilehost.com/?fid=457095661767137840
I think this should solve ur problem

This is a mess. Do this:
Download an A2017 miflash package, just like the one you used to wreck your phone. Install it. If the signal works, you have two options:
-Update to official Oreo (it's out for Chinese phones). It should appear as an OTA. After updating DON'T change to other systems. Just stay with Oreo.
-If you still want to install the U system, don't update. take the A2017U package that you had downloaded, and delete the file called NHLOS.bin inside (might be called NON-HLOS.bin, I don't remember). Then flash it via MiFlash just as you did before

I decided the following way I made a backup of everything of the A2017U since the A2017 did not get wifi imei nothing .. so I did use the miflash and put the Chinese version B13, hence I installed the twrp since my bootloader was unlocked. I used the backup and started the system now everything works

Good. If I were you I'd restore to B13 and update to Oreo, but if you're okay with the old U firmware then ok

when I go by twrp still appears the A2017U this can be a problem later? Even though you were the only one who understood me I speak Portuguese English for me is a bit complicated, but every day I struggle to improve. ah already there forgetting I appeared an update here of the b15 but being I updated more goes to the twrp screen I start the system and usually updates more when I go there in the mifavor to see if there is another update appears the old b15 to update again some solution?

I understood you, but I think it would be easier if you also wrote it in Portuguese. I talk Spanish, so I can also understand Portuguese.
So, you want to get Oreo? If you do, you have to use MiFlash to install the chinese B13 update. After that the update to Oreo should appear.

Didn't TWRP get replaced after you flashed the MiFlash images? If so, you can get the recovery.img from the B13 package and install it from TWRP (Install - install image

I have been using Resurrection Remix for about a month now, but when the stock April patch came, I decided to return to stock firmware. I downloaded the most recent flash package from the official Xiaomi site and flashed it via MiFlash. When the phone booted up, I could see every wireless network, but when I chose to connect to any of them, the signal dropped a bit and it said "Connecting..." then immediately "Saved". After a few automatic try, it would just say "Disabled". The router settings are just fine, the phone could connect to it before I flashed stock rom. I also tried to download a bit older patch (9.5.4), which was neither good. After it I tried Nougat, but it still won't connect to the network. The hardware must be fine, since it was working an hour ago with Resurrection Remix. Could anyone help me out? Thank you in advance!
EDIT: Solved. The problem was with the persist partition, which is not flashed during the firmware flash process, so you have to flash it separately in TWRP. You'll have to download THIS FILE (persist.img), move it to /sdcard of your device, then boot to TWRP (you don't have to flash TWRP, only boot in it), tap on "Advanced" -> "Terminal", then type in the following: "dd if=/sdcard/persist.img of=/dev/block/mmcblk0p27". After it, reboot the phone into fastboot mode, and flash the firmware again. That's all.
Wifi works, but sim = 0

I managed to fix the WiFi and SIM (no imei).
Just flash persist.img if you only have the WiFi-issue.
There's a somewhat complicated guide here in the forums as well. Just google "mi a1 imei fix xda".
I'll help you tomorrow if you cant fix it.

Here is solution: : How to restore IMEI permanently after using factory flash
I have the same problem with IMEI, the fix is permanent.
After the repair can be uploaded any rom, including Oreo .
I also twisted up my IMEI. When I tried to downgrade to 7.8.23 it was boot looping. I was trying to solve it for 6 straight hours. Eventually, somehow the phone became unable to boot into fastboot (or anything else) for no reason. (a random shutdown occured during fastboot mode while no command was given). I had to turn to the Xiaomi service, since nothing could be done with the phone. Guess I'll have to use my old nokia flip mobile for 2-3 weeks.

Now that my wifi issue is solved, can I delete the persist.img from my device? Please advice.
Mods please edit the op with a warning not to flash someone else's persist partition, this can permanently damage your chances of recovering your OEM Mac address and other sensors data, there's already a better solution out the called "persist resurrector" on XDA. !!!!DO NOT USE THIS!!!

Thank you so much, Bro. You saved my day. I am getting the similar problem. And ended up flashing multiple ROMs. but nothing worked out until I found your post.

while using this tool make sure you enable USB debugging or it won't work.

try flashing the latest void kernel.
Flashed A2017U b35 Nougat 7.1.1 on a2017 Chinese , USB to PC Hangs (should Restart to work)
Most Important is 2 Sim Showing No Service and when trying to Make A call Saying (Turn Off Airplane Mode to Make A Call)
Despite it Closed , SIM CARD Working on Other Device !!!
Not 100% sure, but it could have something to do with having the wrong radios on the US firmware.
Sidenote, where did you get the B35 update, would you mind sharing it?

It's official Nougat, literally nothing special
I think someone will upload the U files in some time anyways
Right, but what is special is that OTA is the only way it was put out. ZTE never made it available for download from the support page from what I understand so no one seems to actually have the usable firmware available to download in the way others have copies of the official firmware from ZTE support page. Plus since he has the Chinese model it means he probably didn't get it OTA and has a flash able file that he could share.
