XT1635-02 Rom on XT1635-03

I intend to buy the chinese variant XT1635-03 at Gearbest. Is it possible to flash the XT1635-02 rom on it or will I be stuck with the chinese rom? If that is possible, would I receive the OTA updates?

You can flash the every rom you like i have the Chinese version and i flashed the Russian rom on it you just need to unlock your bootloader

Thank you very much. Your answer was decisive for my decision on buying the device, and I think the chinese version comes already with the bootloader unlocked.

It's not a big deal, as long as I can flash the latest roms.

Sorry to bother again, but did you flash the entire rom? I read at other thread that it is dangerous to flash modem, fsg and bootloader from another variant.

I read on another thread that he flashed a -02 firmware without the modem files and no partition wipe (64 vs 32 GB).
Is there a full "HowTo" to go from XT1635-03 Dual-SIM to a XT1635-02 Firmware? Of course, Dual-SIM should still work afterwards. OTA will not work in any way, right?
Are there custom Roms which can be used on the XT1635-03 ?
Thanks

i have a problem

I can not unlock my bootloader with the code of the bike my pc does not even recognize the device in fastboot, it only recognizes as an idle device called fastboot addison s. you know what to do?

Any progress to what can be done with the chinese moto z play?

Hi,
I got Moto Z from gearbest too and it also comes with ADDISON_CHINA_CUST image.
I was able to unlock bootloader with 'fastboot flashing unlock' and then I flashed it to retail 7.0 (via fastboot), then updated successfully to 7.1 (via adb sideload).
Unfortunately it still shows retcn channel and ADDISON_CHINA_CUST as baseband.
Is there any way to change it too?
Thanks!

To be short: no, there is no pracical way to change the software channel and modem version (they are tightened to hardware)
I do no think you receive any OTA but if so do not install them

Thanks for your reply! Sounds like buying a phone from gearbest is not a good idea if you want to receive OTAs and stay with official ROM.
One more thing: after I updated the phone to 7.1 it shows during startup 'ID: bad key' (apart from 'Your device has been unlocked and can't be trusted'.).
When being flashed, it also returned:
writing 'boot'...
(bootloader) Image signed with key bad key
and
writing 'recovery...
(bootloader) Image signed with key bad key
Btw, maybe it's a stupid question, but is it justified to consider retcn channel and modem version (ADDISON_CHINA_CUST) as kind of backdoor? It still not official software (or at least the latter)...

hi

Hi,
I received a Moto Z Play from Banggood as exchange for another phone under warranty.
I unlocked the bootloader, and via fastboot with RSD lite I updated to nougat 7.1.1
but the chineese version fot XT1635-03. I got it from here :https://mirrors.lolinet.com/firmware/moto/addison_cn/RETCN/
This rom is much worse than the original one, it's a chineese rom with only chineese and english language, no play store, no googleapps, no chrome...
At this time, I don't find the way to flash another Rom.
edit: repaired flashing another 7.1.1 custom rom

If you install the Verizon version your device will update automatically

My bootloader was already unlocked when I got it from banggood, which is similar to gearbest.

Install this via rsd lite and you will have updates via ota:

Anyone know if it's possible to lock the bootloader of -03 using -01/-02 ROM?

I am bricked my phone

hello guyz please help I am install bnd L34 firmware ton my bnd-Al10 from firmware finder app and it successfully installed but I am rebooting my phone its boot on erecovery mode and my frp is locked and the bootloader unlock site is down what can I do ,?

bootloader unlock code different from frp unlock code.
installing other device firmware has chance to replace oeminfo.img partition. Changing this partitin often causes locked frp.
If lucky you can wipe from the erecovery that is loading. maybe even couple times. Then maybe it will boot. Other that that there has been no public mention of any fix.

do your best to fix it using hisuite or other methods if you can. if you have twrp that can help if you have stock recovery and locked frp your only hope might be hisuite and if that fails you will need a paid option like dc-phoenix or funkyhuewei. i only have experience with dc-phoenix, and it did fix my locked frp completely bricked phone, but i read that funky also works well but is nearly 3 times as expensive. (15€ vs 50€)

The displayed build number comes from the data part of the update. (Update_*hw_*.zip)
If you reflash again all three files , might be fixed

If flashing again is the answer to solve problem. Use my guide here.
You are on Oreo now so use the top portion. "Flash update"

I don't want to sound like rude or anything.
But I put it all pretty simple, I thought. Like 4 steps
Download files
Put files on SD card
Install twrp
Install file I shared
If that is over your head, maybe you should not have modify and phone.

[SOLVED]*HELP*Stuck on eRecovery - Bootloader Locked

THANKS @mrmazak !!! You saved my phone! And it did what I have been trying to do, the files you gave link of are Oreo! Thanks!
I have an Honor 7x 4/32. I wanted to try the Oreo, but OTA didn't show up. So i checked the OEM unlocking for just in case, and later on, downloaded & installed Oreo update via Firmware Finder app's DNS guide. Checked the compability and BND-AL10 looked fine even though EMUI said BND-L21C432 since the sticker on back said it is BND-AL10. Besides, I couldnt find L21C432 with 4/32 config. So I thought it was rebranded by the guy I bought from.
After update is installed, and it is performed by EMUI, it rebooted into eRecovery and even if i shut it down, it boots back to it. I am a noob and cannot install TWRP on guides because bootloader is locked.
All solutions I found online includes TWRP and I couldn't find a way to flash twrp.img, i get error like "writing 'recovery'...FAILED (remote: not allowed)"
It is called soft brick I guess. What should I do now?
I am so desperate right now... I tried factory reset and wipe cache, still on eRecovery. Drained the battery and tried again, no change.

4. After phone finishes and reboots, unlock frp and bootloader, if needed
5. Use Huru or HWOTA to flash correct firmware for your model/ region.

Update a locked P20 with stock roms

Hi to all,
i have a P20 branded (and with bootloader locked), with verey delayed software updates.
I would like to if i could update it using the roms downloaded through Firmware finder, and which is the procedure, since i tried to download the latest update.zip found on FF, unpacked in the dload directory of my phone, rebooted on stock recovery (vol up+vol down + power) and had a generic error.
thanks a lot for your informations.

Packing yourself a 'non-working' dload with extracted update.app from original firmware found on Firmware Finder won't work...
To force an update with a locked bootloader, you could :
-Try to update with FirmwareFinder's DNS, Hisuite 5 and an IMEI-approved OTA-MF ; You'll be updated without any userdata erased.
-Use a working dload firmware for your model and cust to update. Download said dload archive for free from http://androidhost.ru ; Your SDcard or your USB-OTG must be ExFAT formatted for dload update to work !!!
All your userdatas will be erased this way.
-Buy your bootloader's unlock code online from a third-party. Unlock your bootloader. Install a working twrp custom recovery. Use HuRUpdater with any updated firmwares for your model and cust you can find with FirmwareFinder. You'll be updated without any userdata erased.

Working dload archives should upgrade fine with your model's and cust's archives.
Working dload archives should downgrade fine with unlocked bootloader.
Only some users are reporting successfull dload downgrades WITH a locked bootloader on SHT and CMR for now. Most fails.

Question Possible to go from 8 Pro + CN to EU version?

A bit sick of the UI but worried that since the 8 Pro + version is not available in Europe there may be issues. Is there anyone who tried this? Is it possible to install stock firmware from another region?

I know this doesn't answer the first part of your question directly but it works the other way. I have installed CN on my EU model. Interesting that there's a few extra settings in the CN such as updating the GPU directly.
I'm on the latest CN firmware V2.26 and the battery is much better but probably due to all the battery saving default settings.

Yes, you can change the payload_properties.txt in the rom of the region you want to flash. Change the text "nx729j_un" or "nx729j_**" for " NUBIA_SUBVERSION to "nx729j". Put the modified rom in the root directory and use local update. You do not have to unlock the bootloader to do this. If this does not work then you have to unlock the bootloader and flash the recovery of the rom in the region you want to change to and use sideload to flash the rom. However the second method might mess up your phone and you might not be able to boot your phone.

In the payload_properties.txt, change the text "nx729j_un" for " NUBIA_SUBVERSION to "nx729j". Put the modified rom in the root directory and use local update. You do not have to unlock the bootloader to do this. If this does not work then you have to unlock the bootloader by go to bootloader and in the command window type
fastboot flashing unlock
Follow the direction to unlock the phone
You need to extract the payload.bin from the CN rom, then use payload dumper or fastboot enhance to extract recovery.img from the payload.bin. Go to bootloader and flash the recovery of the CN rom (fastboot flash recovery recovery.img)
Then reboot to recovery, choose English when you see "Wipe data" type
adb reboot sideload
Once your phone boots into sideload mode (When you see the two error line at the bottom of the screen) type
adb sideload NX729J-update.zip (this is the CN rom you want to flash)
Whether the transfer is successful or not you can wipe the data and reboot the phone. If the transfer is successful you will be in the CN rom, if not you should be back to your own Global rom. The sideload will load the new rom to the other slot so it should not change the current slot.

I'm terms of unlocking the bootloader all I have to do is go into fastboot mode (with OEM unlock, USB debugger selected on the phone of course) and type in the "fastboot flashing unlock" command and whatever next steps I'm supposed to do? Also I have not set fingerprint and or security pin on this phone yet and I've read that people are having issues with them after unlocking bootloader. Is your bootloader unlocked? If so are you having pin/fingerprint issues and if not was there anything you need to do to avoid the issue when unlocking the bootloader? TY!
