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.

How to revert to AL10 from BND-L21 with no unlocked bootloader?

Hello,
I have a Honor 7X BND-L21 bought from Aliexpress.
The phone's firmware was updated from AL10 by the seller before shipping.
I'm basically trying to get a bootlocker unlock code from the Huawei website but the site doesn't give anything after filling in my details.
I was wondering if it's possible to revert back to AL10 without unlocking the bootloader? I want to check if I can get an unlock code after reverting back to AL10 as it's the original firmware.
I've tried firmware finder and it shows there are new updates available but every time I try to install the latest update it fails for some reason.
Looks like I'm not getting OTA updates since I'm still on a security patch from October 2017.
Thanks!

If you download the dc- Phoenix tool you can flash what ever firmware you want with a locked bootloader or not the only thing is it cost 15 euros but it's worth it you get the tool for 72 hours

Bootloader Unlocked L29 C636 owners please help

Question for those of you on L29 model w/ C636 region.
I purchased a bootloader unlocked EVR-L29 from a forum member here but don't want to bother him with more questions.
QUESTIONS:
-I am on version 9.0.0.7 I have tried manually updating within the phone itself but it says I am on latest version.
I downloaded latest HiSuite program on laptop and connected the phone to it using usb debug in dev mode. Still says on latest version. I have attempted to go into erecovery & force searching for an update. Which sorta worked but it just downloads the current version I am already on.
So I am guessing I am having these issues because it is bootloader unlocked?
I am guessing you bootloader unlocked guys have an alternate method of forcing an update?
If there is an alternate method I can use I am guessing it is best to incrementally update instead of pushing the latest build?
-Once fully updated to the latest build will the old root method still work on EMUI 9.1? Where we flash a recovery ramdisk as shown HERE?
If the answer is yes do you all flash a stock recovery ramdisk for L29 or a patched recovery ramdisk? What is the difference?

I unlocked the bootloader on my L29 and was on 9.0.0.208 and couldn't get the 9.1.0.300 OTA update until I used e-recovery to download and install 9.0.0.207. Once I did that the phone immediately received the 9.1.0.300 OTA update and then patch #1. I haven't rooted yet so I don't know if root survives the update. It might because the update didn't wipe anything.

Yup erecovery just keeps downloading and installing 9.0.0.207 and when the phone reboots I get no OTA. Odd. I'll try putting the sim card in to see if that helps since I'm using wifi

Update for any people in the future that have this problem.
NO METHODS WORKED except Dload method. Finally on .310 update.

Question Help with TMO OP9 Pro (LE2127) A12. What are my options?

I thought I was buying an unlocked global version but goy the t-mobile version. Are there any options for unlocking the boot loader without an unlock.bin?
Additionally, once the bootloader is unlocked (if I wait for the .bin from OnePlus) what additional considerations are there for flashing firmware and rooting the device? I have been trying to sort through the forum with minimal luck.
It lools like MSM will not work without unlock.bin on A12 and later, is that correct?
If i unlock with unlock.bin can I use the OTA firmware from OnePlus site to flash and root, or do I need TMO specific firmware and where would that be located.
Any links to applicable guides would be greatly appreciated.

You are going to be ok. I have the OP9P with stock A13 with unlocked BL, rooted with magisk . Unfortunately I am leaving on vacation and will be limited when I can guide you along but be patient.

I just delt with this last week, and was able to convert to global and OEM unlock without having to use an unlock code from OnePlus or from tmo.
What you need to do is convert your model from LE2127 TO LE2125.
1. Download MSM for tmo OP9Pro, this will be handy if you mess anything up
2. I don't have a link but if you search TMO to EU MSM OnePlus 9 pro you should be able to find the right tool. You just run the MSM like you always would.
3. Now you can OEM unlock your phone by running the command `adb shell pm uninstall -k --user 0 com.qualcomm.qti.uim`
4. Your phone is now no longer TMO but will not work with a US sim card, so you need to convert it to global. You can just download the OTA from OnePlus official website and go to software update in settings and press 3 dots and press local update or something like that.
4. After installing global software, upgrade to newest software version via OTA updates
5. Once complete, reset phone through settings.
6. ???
7. Profit
If you need any help with any particular step let me know

I have the TMO to GLO MSM Tool and will give link tomorrow! I will be on the road for about 10 hours tomorrow, that is why it will take a bit to get the link posted to download the MSM Tool.

Give me a little bit and you will have the link. Don't want to keep you waiting.... Fastboot OEM unlock once converted. Enable developer options, USB debugging and OEM unlock....

Also if you want to get back to stock after unlocking bootloader, let me know....I have the answer for that too!

If you stay with Global, you might need to flash TMO modem if your carrier is TMO.

Here you go... TMO 2 GLO MSM Tool....
3.52 GB file on MEGA
mega.nz

So while I was waiting I got impatient and started playing around with different MSM packages. The problem I now have is that after flashing to either TMO or Global I can no longer toggle OEM unlocking.
The phone was network/sim unlocked before I started and now, even if I get onto an A11 non-TMO ROM I cannot enable the setting.
Edit: After reapplying TMO ROM and going online it has re-enabled. Will try the suggested path now.

Use the link I uploaded to go from TMO 2 GLO, if first try does not work, uncheck the "SHA" and check the "USE LITEFIREHOSE" boxes.

Be sure to read all that I have posted. Patience is the virtue to success...

I will get you where you want to be, but you must be patient!

To root you have to use a a version of TWRP A12 to sideload a A13 TWRP then install magisk from TWRP..... Use magisk v26.1
