GUIDE: How to FLASH and RESTORE your STOCK firmware on the TA-1054 (and others)

It seems like there are a few people having trouble going back to stock and getting everything working.
As always, this requires an unlocked bootloader. If you don't have an unlocked bootloader then search google for a $5 service that does. It is what I did.
I flashed Project treble on my TA-1054. It worked great except it kept saying "insert SIM" when there was already a sim card inside, so I could not use it.
I tried to go back to stock but that firmware file on that google drive thread was corrupted, bad upload. Took me a few days to source this original firmware.
There is a tool called OST ( around 115MB), and a patch that comes with it (the smaller file less than 1MB)
The firmware is almost 2 GB
Download everything, including firmware.
1. Install the OST tool.
2. Replace the EXE file in the program files with the patch file you downloaded.
3. Delete the Onlineupdatetoolexe.config file. If you don't do this, the program will not start correctly.
4. Put phone into download mode ( either by powering it off, pluging into USB cable and immediately hold power and volume down. Or if you can boot into android with ADB debugging, just do a adb reboot bootloader.
5. Pick firmware file and click next.
THe first 2 times I tried this, It hanged at the last second. Third time was a charm. Give it time. Use a good USB cable.
I assume that this is the same way to flash other firmware files for other devices.
As soon as i get my hands on a android one firmware, I will flash it.
Or if anyone can guide me on how to extract the firmware on my TA-1045 USA version and flash it to my TA-1054 Chinese , let me know. Cheers.
Google drive folder with all the files I uploaded.
https://drive.google.com/open?id=1NbzO6lfSGacjM2wqrtBg3jMpljsZswne

Thanks bro...I am downloading it.

PL2-2380-0-00WW-B01.NBx.zip is global firmware name. firmware size is 4gb.

thanks! for extract is with nb0 tools FIH Mobile v3.4

https://drive.google.com/open?id=1cSgjrZUxIsN7oLbo7AP-RnILDZdswmB-
its android one firmware. I have no tool for flash...plz try and let me know

Flashing now. Will report back after flashing is done. thanks!!
Edit: Looks like the version I have for OST does not read NBX files. Will try to update that and report back. I have ntool but no working username password

I cannot flash the NBX file. I changed it to nb0 but OST LA says cannot read firmware. Is there any other way to flash?
EDIT: I went ahead and purchased a bunch of credits for NTOOL.
I will flash and see if it works!

It fails with the mdtp.img partition (no such partition) . I would think that it would just skip that partition but it did not. I will later try to extract and flash separately

For some reason when I try to flash the golabl firmware using ntool, my bootloader gets locked after the mdtp flashing fails and I have to re-unlock my bootloader and flash the original 7.1 chinese firmware using the OLD version of OST. ( the new one kept saying firmware corrupt)
When I bought the credits for Ntool, I also got access to the downloads section so I will be uploading all the firmwares they have, ( there is like 5 different ones)
I was reading how the nokia &+ users are converting their chinese variants to global variants using the android P beta rom.
We also have a P beta rom so I will be trying to install that to see if it works or not.
As some of you may realize, I am determined to make this happen! The reason is because my USA android One version has only 3gb of ram but the chinese version comes with 4GB.

can u flash my chinese rom which is nbo format via ntool. I have have ntool but i dont have user name,password, i downloaded rom which u provide.my device still cant connect to mobile data.

NBX format only works on Ntool. but Ntool needs working user name and password to works. OST cant read or flash Nbx format.
if u get Ntool with working user id .. then plz flash my device also via remote mode like teamviewer.

Ntool Bricked my device. the only real restore you can do is by using ost with the stock chinese firmware. edit your apn. why is your data not working?

Global rom cant flash via ntool in Ta1054..showed error in partition. if it will be solved then china to global will be easy process..

I'm eagerly watching your progress. I'm in the same boat sitting on a TA-1054 wanting to get on Oreo without chinese firmware :x
Keep up the good work. It is really appreciated!
Edit: By the way, are the custom and original chinese firmware files available anywhere?
I saw someone mention a firmware in the google drive for TA-1054 but I'm uncertain whether that is the official one or the custom one.

Its the Chinese official ROM you get it from Google drive folder in Nokia 6 mena firmware topic

Actually, the one in the mena topic was corrupted for me.
I have uploaded a good version in the first post of this thread. I've only had success flashing it wih OST.
But yesterday Ntool bricked my phone. No download mode, no screen, no usb recognition with windows. I am not really sure what to do now. If i can't get my pc to recognize it then the phone might be dead./ I may do a warranty exchange when i go visit china next month but if they check my bootloader, they will void my warranty. anyone know how to unbrick?
Also. The nokia 7+ forums said that if you flash the android P beta rom, then the chinese vaqriant becomes gloabl.
I went ahead and downloaded the android P beta for 6.1 but now that the phone is bricked I can't really test anything. I will sell my extra 1045 before i get curious and brick that too.

Can you share the link for P beta for 6.1?
Also, I own a TA-1054 model and I am in India. I ordered it from Amazon. It had Android One Oreo firmware preinstalled before I messed up and got loops. Later I flashed a GSI to at least boot it up.

I put the original chinese firmware on the first post.
There is an option to install google play store, but that would make your rom unable to receive updates.

Removing Retail Demo to Stock

Hi @All,
i have an Retail Demo Device of the P30 & P30 Pro and i want to use it as daily driver, but i need to get rid of the Retail Demo App & the Marketplace Demo.
My idea was to unlock the bootloader and flash the stock rom on it. Is it possible like that and does any1 have an clue where to get the Resources (Bootloader Unlock & Firmware files + Flasher)?
Thx in advance

For bootloader unlock i belive it s work with dcunlocker program, it s 4euro. Somebody worked ?

It's not on their "supported device" list. That ends with P10/P10 Plus. Same with their HCU Client: it also doesn't support the P20 & P30 Series, not even Mate 10 Pro on Android 8 upwards
But thx for the idea

Here i found firmware :
HUAWEI P30 ELE-L29 HW EEA ELLE-L29B 9.1.0.115(C431E4R2P2) FIRMWARE 9.0.0 R3 EMUI9.1.0 05015RBQ

Any progress/solution with it ?

Well I did and it comes back on factory reset

The name of that package to remove retail demo on Huawei phone P30s are
com.huawei.retaildemo and com.huawei.experience.mar.can
but for the experience package check the phone with package inspector app because the end might change (the .mar.can part)

It will come back on factory reset, since the app will be uninstalled for current user only.

Any luck?
I'm considering purchasing a p30 pro that was previously used as demo unit. Need to know if it's possible to get the app off.

https://youtu.be/8Sq9KQq2vrA

Hi all,
I've been walking around this prob for two days ...
At the moment I was able to delete the demo apps, but something about the demo always remains.
No block of type can be set.
If you reset the phone (volume+ and power button) the demo apps come back and start working.
I think it is necessary to do something else...unlock bootloader ?? I also found nothing for this solution.
Anyone ??

I think these retail demo units don't have baseband/modem files installed. I haven't customized (or even rooted) phones since my Note 4 but I remember I could load all the appropriate files in "Odin" software and flash directly to the phones. With these Huawei phones it's possible that best we can do is turn them into ipod touch type of devices
I thought I was getting a good deal on a retail demo model and figured I would be able to use the phone once everything was flashed but I now think I got ripped off :crying:

No modem or fingerprint hardware in the S7 or S9 demo units either (Likely all the other models too but never owned them), Samsung do the same, likely all manufactures do it to save on hardware for phones that will never be used as phones, or at least were never intended to be

The method is to unlock the bootloader and then put the stock version of europe
You can also try this method - https://forum.xda-developers.com/p10-plus/how-to/p10-plus-to-stock-erecovery-dns-ff-t3730077 but with the software for the p30 pro
But the safest thing is to unlock the bootloader and after that put the clean software...
Phone have all function ok, but demo mode limit this functions! So, here one video after removed this function, but this guy request 60
euro for this "what, no whay" .. But this it's the point, all function works normaly after remove demo mode or change the soft!

CN Ver. with flashed OS

I ordered a new phone and just spotted that its "CN Ver. with flashed OS":
1. Do I need to worry?
2. Does that mean I lose the Widevine and Google Pay support?
3. Can I reset manually reset the phone to "stock" international version (just in case it comes with a virus etc.)?

I think it's T-mobile Variant

I assume they mean a custom ROM (flashed by the user). All ROMs are "flashed". How else would it get on the phone?
1. Probably not.
2. You don't "lose" Widevine. It drops Widevine status from L1 to L3. Which means Netflix reduces the video resolution from 720p to 480p (and apparently also some other video services like Hulu, Amazon Prime, HBO). Widevine L1 status is restored if you return the phone to stock condition and relock the bootloader.
I don't know about Google Pay on a custom ROM, but it works fine on the stock ROM with root.
3. Yes.

This is actually from eGlobalCentral who are basically a Chinese seller, but with depots in Europe...
(So suspect they are taking stock CN phones and flashing with the international stock ROM - but who knows)
As long as I can "reinstall" the international version + boot loader (and re-lock) without any limitations compared to the official version (auto updates, full google pay etc.) I can stop my worrying...

I think you're fine! Granted they don't send you some clone device and it's REAL OnePlus hardware. The MSM tools that are floating around here on XDA will restore the device to stock and lock the bootloader for you, so no worries there, just make sure to use the correct MSM tool for the device you end up with.
Side note, I notice for me anyway that the MSM tool only flashes one partition, it's a good idea to do a local upgrade from the phone itself after using the MSM tool, just in case.

There won't be any issues with fake hardware (have used the site a few times before) - they are just poor at communicating when an item is in stock in Europe versus in stock in China (with the extra delay of it being shipped to Europe warehouse) - but they consistently have excellent prices.
(with all the delays I might just go straight to the Q beta!!!)
Thanks all!

Please share your experience
Hello, hope everything went well with your oneplus device?
Did you manage to install oxygen os on it? Did everything else worked will like playstore and all?
Please share your experience, I am looking to buy one from eglobalcentraluk, any information will be appreciated.
Kind Regards,

i think the CN version you're talking to is the CHINA VARIANT GM1910 ??? these variants have hydrogen OS installed out of the box,,
but there are some sellers who tampered it and install Oxygen OS then reseal it ... JUst like mine,, Im from the Philippines and i opt to buy a GM1910 china variant FLASHED with global rom (OXYGEN OS) because of the GOLD WHITE COLOR
and because it's now in OXYGEN os, it has all the GOOGLE PLAY SERVICES installed. and lastly,, the WIDEVINE L1 is still intact.. you will only loose it if you unlock its bootloader...
GM1910 is the Chinese variant OnePlus 7 Pro running HydrogenOS (with GM21 build tag).
It is possible to flash both GM21AA (global) and GM21BA (EU) OxygenOS firmware on top of the HydrogenOS using the Local Upgrade method.
Bootloader unlocking is not necessary for switching to OxygenOS.
After conversion, you'll get OTA update from the respective branch.

Google Pixel 3 noobie queries

Hi!
I come from the Galaxy S series (S4, S5, S7) phones and I m considering of buying a Google Pixel 3
I can find many decent options, all of which are carrier unlocked
My concern with the Pixel 3 is whether I ll be able to install Android vanilla (without any carrier-related bloatware)
For all of my Samsung's so far, I could easily pick the retail ROM (well not exactly 'vanilla'!) from sammobile and load it with Odin (without breaking the knox)
Can I do something similar in the Pixel 3 or are there any security mechanisms to prevent me? (I m talking about installing original ROM - not custom..)
Bonus question - does any of you know if the Pixel 3 from Verizon and US Cellular have branding [carrier logo(s)] on the device?
Thank you in advance!

Well, you will certainly avoid the Samsung bloatwear. I have a P3 from Google and got my son's P3 through T-mobile. It did not have any additional T-mobile bloat on it, but I don't know about the big V.

I can find it via Verizon and US Cellular - hopefully none of which have put logos on it..
I have one more - rather embarassing question: do you have to use a Google account in order to use the Pixel 3? For several other Android phones that I know of - it's optional. You can still skip this step and use the phone without having to tie the phone with Google. But can you do that on the P3?
Any more hints on that and my ROM-related queries would be really helpful! Thanks

Verizon branded Pixel 3s have locked bootloaders, which prevent rooting or custom ROMs (vanilla AOSP would be a custom ROM). According to the flashing instructions at https://developers.google.com/android/images, you also need to unlock the bootloader to flash a google factory image.
I'm not sure if you can skip the google account. If you really want to avoid google services, my recommendation would be to install LineageOS, with no gapps.

Hmm...if the 3s has that, then the 3 will also have it :/
But I m confused...would I be able to unlock the bootloader?
I can see from this page: https://developers.google.com/android/images#blueline that 'blueline' is that vanilla AOSP version that corresponds to the P3 (right?)
The G account issue is less important. I just don't like 'syncing' stuff (accounts, photos etc). Worse case scenario, I ll create an empty profile, just for the logon

3s is not a model, it is the plural of 3. A Verizon Pixel 3 usually cannot be boot loader unlocked, but if you search this forum, you will find a few special cases where it has been done. One such case is at https://forum.xda-developers.com/t/...branded-pixel-3-how-is-this-possible.4267273/
Vanilla AOSP generall refers to a ROM without any google services. See https://android.stackexchange.com/questions/53171/what-exactly-is-in-aosp for more info. Blueline is the Pixel 3 factory image, which has all the google services. It does not have any added carrier bloatware, but I wouldn't call it a vanilla AOSP.
You can turn off all the syncing stuff, and you may be able to skip the google account part. I just can't definitely say you can skip the google account because I have not tried it.
Another consideration with a locked bootloader is the end support date. Google support for the Pixel 3 ends in October, 4 months from now. There will be no security updates from Google after October. If you have an unlocked bootloader, you can switch to LineageOS and continue to receive security updates. That is what I plan to do.

Clear!
I ll check on the resources you ve listed here
If the V-branded P3 is troublesome as it sounds, perhaps I should just go for the US Cellular carrier option. Bootloader may also be locked (but we know for sure that the V is..)
Interestingly, the US Cellular P3 is unlocked to all GSM carriers except Verizon, Boost, Virgin Mobile and Sprint
Is the carrier lock specified in the bootloader?
Btw, thanks for all the help!

Is the carrier lock specified in the bootloader?
Btw, thanks for all the help!

SIM (carrier) unlock and bootloader unlock are separate, and not related. I have no idea if US Cellular is bootloader unlocked. Google sold a global model, which is the bootloader unlocked version, and the one I have. The IMEI/MEID number of the global variant begins with 990012 (don't know how many digits are significant). If I was buying it, I'd ask the seller to confirm it was bootloader unlocked.
Glad I could help.

The two P3 options I m considering (Verizon + US Cellular), both are sealed in their original box. According to that post, if the P3 hasn't ever being turned on, which is probably then when bootloader becomes locked
So I wonder if there is a SIM that comes with the phone already and that I have to remove that prior booting the phone. Not sure what he means with "VZW SIM". Is it a different type of SIM e.g. an eSIM??
I know for fact that these phones are CDMA-locked and only GSM is unlocked (but that's what I need anyways)
Does anyone here have any experience from an US Cellular P3 - is the bootloader locked? (the retailer of the phone doesn't seem to know much on such details..)

VZW SIM is just a Verizon SIM. It is probably the standard SIM card, not an eSIM. I would remove the SIM prior to booting, just to be safe. According to one of those posts, WiFi had to be connected before they could unlock the bootloader.

I ll find out soon, I ve ordered the P3 (US cellular stock)
Seller claims that it is sealed in original box. If that's really the case, then the carrier can't have put a SIM into it, right? But what about an eSIM? If they have the eSIM pre-programmed, then I can't possibly avoid booting the phone with it..

Hmmm I think the way it works is that when the phone is produced, for a specific carrier, and the carrier wants it to have a sim, it's put in at the factory. So, I think, sealed with a sim in it, possible.
I don't think us cellular uses e-sims. Double check that but it doesn't look like one of the carriers that's capable of e-sims.
cheers, good luck. I have a vzw coming today, hoping it's new and can unlock as others have... we'll know soon.

Good news! Just got the phone and ... I ve managed to unlock the bootloader!
Exactly same case as described here. No SIM inserted, connected to WIFI, and in Dev Options, turned OEM unlocking to ON!
Then, on the instructions (link by opensense), I ve used adb and the bootloader is now unlocked! I m really chuffed about it
(btw the US Cellular supplied SIM was attached on the box (outside) with a sticker. Box was sealed.
Now, all is left is for me to pick that 'cleaner' Android option I always wanted!
But which one should it be? It's currently running blueline MP1.0(ROW)
Is there any clearer (official) Android ROM that I should switch to instead?
From G services, I would like to keep the Playstore and Maps...

Congratulations. You'll have to define what you mean by the term "cleaner (official)" ROM. Blueline is the only official Google ROM for the Pixel 3. Anything else will be a custom ROM. I have no experience with any of the Pixel custom ROMs, so can't offer any advice on those.
You can disable most of the unwanted Google services in the blueline ROM. I'd recommend keeping the backup service, though.
Blueline MP1.0(ROW) is not a version listed at https://developers.google.com/android/images#blueline Go to Settings, About Phone, and tap Android Version. Check the "Android security update" date. Latest is June 5, 2021. I suspect yours is quite old.
If you want to update to the current blueline version, you have 2 options, OTA or flash a new factory image.
For OTA, go to Settings, System, System update, and follow instructions.
To flash a new factory image, follow the instructions at the link above. To prevent wiping your data when flashing, edit the flash-all.bat or flash-all.sh file, and remove the "-w" from the last line.
I you intend to change ROM's, I wouldn't bother updating.
Good luck.

I think I ll probably stick with the official one then. My current is PQ1A.181105.017.A1 (which is very old as you guessed)
Which means I can jump to Android 10 or 11. From my experience, latest isn't always the best so I might have to keep reading, see if I should jump to a latest build of 10 instead. My emphasis is on stability/security - not new features...
And I want to ensure that the camera is at its best

If security is a concern, you'll want to go to Android 11. 10 has not been updated since August 2020, when Android 11 came out. Also, I believe there have been camera improvements since August 2020, which would not be in the latest Android 10 build.
I have not seen any reports of stability problems with the June 2021 Android 11 update, which has the latest security patches.
I don't know if you can do an OTA update to Android 11 from Android 9. You might have to go from 9 to 10 to 11. You can flash the Android 11 image without going to 10 first.

I intend to do via flashing (whichever version I decide in the end). Not a fan of OTA

Question how to unlock my bricked Redmi Note 11 Pro 5g (China:Pissarro) Bootloader

hi, i updated my phone to MIUI 13.0.3 android 12 and i've noticed a bug that made all the apps that are using the camera like instagram and snapchat take blurry pictures like an effect getting applied to the pictures taken by those apps (everything normal in my stock camera app) so i decided to use MiFlash tool to flash the previous android version on my phone but i bricked my phone instead i flashed a global rom while my phone is the chinese market version and accidently checked the ClearData+lock Device check box in MiFlash. the tool flashed the rom successfully but when the phone restarted it showed me a message saying that this rom cannot be installed on this device in recovery mode i couldn't do anything after cuz the bootloader got locked too T i tried everything to unlock it (mtk Client - bootloader unlocker+ adb fastboot + Xiaomi Unlock app ...). please help me is there any way i can fix my phone and what is the righ Rom to flash on my phone (Redmi Note 11 Pro 5G China (21091116C - Pissarro). thnx

friend I'm not a star I tell you how things are 1) you can't go back with another Rom only china 2) anti-roll-back 3) MiCloud you have to disable it you can try MiflashV2 there is also to unlock the bootloader it does everything even the firmware remember if the firmware does not start. important not only china also not china for updates remember first you do the factory reset put google account do not update any app except google drive backup with drive if it has arrived update it is better by setting the time instead of downloading the package the problem is when the update occurs it fails to close all active apps and then there is MiCloud that blocks. Best wishes and good luck and that I have little time for me too much trouble here in Europe.

currently my phone is stuck at the logo and after seconds it loads Fastboot automatically i cant access the phone os to do anything i used the xiaomi bootloader unlocker app that works online but it didnt work . the local cell phone service shops told that they have to open the phones back case to fix it ... i dont want that i've just bought the phone didnt even use it for a whole month

they don't have to open it they use licensed or dongle software (USB type) currently I use unlocktoll.net but if the phone is under warranty and you haven't removed the bootloader before it is better for you. It is possible that others have the same problem as you. Good luck

Rule number 1 for Xiaomi never flash anything on Mediatek devices, it will fail. If messed up, no way back as Xiaomi locks the devices for autorized service providers or local Xiaomi branches only. If you want to play with Xiaomi custom roms/development/etc. related only buy Snapdragon based devices.
I i.e. learned it the hard way, when this all started with the Redmi Note 8 Pro, I bricked it by flashing twrp in Android 11 and Xiaomi didn't want to repair it, so I had to pay some russian guy to fix it via Teamviewer with a modified unlock tool which was able to answer the unlock requests by pasting the answer manually from a generator. It's not like I messed up at a point, it's just that Mediatek devices easily fall in a unrecoverable state. In my term it was the combination of Android version and twrp. You will note there is no Mediatek support on xda and even when your device is named like a Snapdragon version, your device is offtopic here, because trying anything on it beyond unlocking the bootloader is harakiri

how to unlock my bricked Redmi Note 11 Pro 5g (Chinaissarro) Bootloader​
Congratulation. Brick without unlocked BL :/
my opinion: you are done....
Some Xiaomi devices have pins on motherboard to
switch EDL, but i dont know with this device.
Try complaint and say something like: "my phone was upgraded and then i see only logo"

I did the same with my device. You can fix it using the MTK tools guide. Its lengthy but easy.
