Question Lenovo P11 TB-J606F Invalid serial number - Lenovo P11

Hello from Greece,
Yesterday i received my new tablet P11 (6gb/128gb) from a well know chinese e-shop (banggood)
And i have some questions.
The seller stated that model is not Global Rom, is third-party rom and support google play store and multi languages. It doesn't support Widevine L1 and ota update os.
but it came with the rom TB-J606F_S320029_210923_ROW (see picture bellow)

}
and after 5 minutes in the update section notifies me for a new version TB-J606F_S320158_220217_ROW.
After the update I login to my lenovo account and then I tried to register my device.
Questions:
1) When I put the serial number in the registration form it stated always "invalid serial number"... (see picture bellow)
2) How it recieve OTA update, is that an official rom against what they stated?
3) When I checked the DRM info app it stated that the current level is L1 (see picture below)
Thanks in advance

I guess the box says Xiaoxin Pad not Lenovo P11, if that's correct that's the version only sold in China and that's why your serial number is not recognised.
Your Widevine L1 means that your bootloader is locked, you can verify that doing a reboot to recovery, only official ROMs can be installed with bootloader locked.
In short you are not going to receive support because that tablet is not supposed to be sold outside China but since the hardware is the same as the one for global market (P11) and ROM installed is the proper Global you should receive normally OTA updates.
One thing you should check is if they properly set the region:

Guys, use method from Post 3 and this link: http://www.emui.com/plugin.php?id=unlock&mod=detail
You have to register, but it works
Worked fine for me!
Try Huawei Y300-0000 or Y300-0100

Click to collapse
I found this method and ITS WORKED! For everyone who want to get your code here is a method which work for L09
You have to use Huawei Product ID Generator and this site to get your code, use translate to register
The EMUI site needs a China registered phone number in order to sign in... how did you guys if non China based users overcome that restriction ?
You dont have to register by number, at right probably, you got a option to register by using email. Translate this page and you should find that.
good news everyone!
the unlock code generator at emui.huawei.com<slash>plugin.php?id=unlock&mod=detail now has Ascend Mate 7 MT-L09 in the model list
the easiest way to register is via bit.ly<slash>1Ffl7Ti
I roamed around differetn posts and websites about unlocking the bootloader.
I was looking for a replicable procedure (also for my son's and a friend's phone) and this is the best one I foud:
website.
It worked first shot on 3 Mate 7 Gold.
Explanation and procedure is quite well written and simple as it could be, consdiering that no one-shot-unlock software exists for our phone.
Thanks so much for the link!

G935ATPV cross bootloader,flash Chinese Version , support ALL lte band,Knox stil 0!!

http://bbs.romup.com/thread-80587-1-1.html
This post said the Their method is applicable to all of the Samsung machine locks BL.
They are already do this,and will not share the way..
It is said that ,the G935A,G935T,G935P,G935V cross bootloader flash Chinese Version ,and support ALL band(gam,cdma,wcdma ,tdscdma,lte) ,all carrier,all
country..
And I get a S7 EDGE G935V, It unlock and flashed, following the picture
I think there are three possible ways to achieve this effect.
1.、use odin flash the eng kernel,and root. then use Z3X or other box to change the Bootloader Recognized identifier
2、Making a special data line, to achieve strong brush the other version of the firmware. (The other phone use this way..)
3、Modify other editions Samsung firmware identifier,To achieve the bypass bootloader to flash the other version.
There are many experts in the forum, I'm sure you'll find interesting
I hope someone can share the way when he successful
Ignore my bad English...

I am very pleased to see so many reply.
I see the reply ,and generally do some answer.
1、The phone is T-mobile,It seems that it flash the Version Version frist
2、After flash Chinese version, the bootloader is still locked
This is really strange, the S7 and S7 EDGE ,US version in the US no one cracks, but it cracked in China and they started to do Paid services..
In ShenZhen ,they flash a phone ,charge $ 20

Is it possible to switch GM1910 to European ROM without unlock or root?

Hi all,
sorry if this has been asked and answered (I did search first).
My daughter ordered a Oneplus 7 Pro from a European seller but it arrived with Chinese writing on the back.
A quick search of the text "GM1910" reveals it to be a Chinese model (see picture)
So our options are to try for refund or if possible, change the OS.
So my question is, is it possible to change the ROM to European (UK) without unlocking the bootloader or rooting (she uses apps that wont work rooted/unlocked)
Thanks, Steve.
(EDIT...)
Some additional questions...
* What ROM is it likely to have pre-installed?
* Will it have English already?
* Is it likely to be littered with Chinese apps?
Back of box...

I bought a GM1910 and it came with Oxygen OS, not with the Chinese version. Currently it's updated to 10.3.0.
Just open it and power it on.
I think these are sold in HK market so it comes preinstalled with OxygenOS

Hi xander, thanks for the heads up.
You were correct, it did have oxygen (v9.x) so I got the EU rom and did a "local upgrade"
For anyone reading this in future...
1. download the GM21BA EU ROM (V10.0.3 at time of writing)
2. copy it to "internal storage" area of phone
3. in phone, open settings > system > system updates > menu (gear icon) > local upgrade
easy peasy.
Cheers.
As long as the update is the same or higher then what you have on it now. Let's say your on the 10.0.3 gm21ba which is the 1913 then you can download the update gm21aa 10.3.0 for the 1917 and will succeed. I have the 1910 and done this quote a few times. I read the the 1910 is the only one that can be cross flashed but that I have not tested. Flashing didn't really change much in my opinion. Also you won't get any additional lte bands with just by flashing. If you do update and your stock and bootloader is not unlocked then you cannot downgrade unless you do get your bootloader unlocked

One question: How did you know it is China ROM. I had one but the firmware ends in ROW. Is this global version? What updater did you use? I used LMSA and it queries on the hard code key in selecting the firmware. I used 62 and my Pro 2020 is now android 11. Quite easy upgrade. My issue before and after the update is that it does not run Netflix nor can I uninstall it. I do not know why...

You need to change Region code from China (01) to Global (02) to fix the issue

Question Switch firmware versions // Remove China censorship

Hi everyone,
i'm currently living as an expat in China and will do so for the next two years.
I bought a Samsung Tab 7 FE here in China and would like to switch my firmware version to the international or european one to get rid of the censorship and not being able to install certain apps like Maps etc.
I've read through the recent rooting thread, unlocked my bootloader and got Odin and Frija downloaded.
What i can't find is the international firmware version of my device.
To make it clear:
Model Number: SM-T735C
CHC: CHC
Frija suggests this file:
SM-T735C_1_20211123165801_q8v4albsaf_fac.zip.enc4
But this will probably just update my firmware to the latest China firmware, right?
I also looked on sammobile but they seem to not know my device...
It should now be possible to do what i'm trying to do, can somebody give me some advice how to proceed?
Thanks in advance, have been waiting since June to get rid of this firmware
Did you ever figure this out? I'm in the same position now and was looking for an answer to this too.
The "C" means you have a special hardware variant for China, it will not work with non-Chinese firmware. Your only option is a custom ROM, and with Samsung's recent moves against those, good luck.
Hardwarewise it's exactly the same, just got the restrictions on the software side. Unfortunately i've not figured it out yet @citizenjack, currently i'm using it only for media where i works just fine. I think sooner or later someone will come up with a solution
you can try this

Can you explain why you think this could work @chsey1 ? I'm afraid i'd brick my device, not even the model is the same.

This won't work as it's the "C" variant and it won't accept this firmware.
