Hi,
As you probably know, p2c72 is the Chinese variant of P2a42, or the other way around. Anyway, I start this thread as I've had nearly the same experience with k3 note. I had t5 which is again the chinese variant of a40 or sth like that. However, back then if I could remember, I could install anything. Perhaps because the retailers had changed its rom to ROW, I really don't know.
So, is the change here possible? In fact I assume when we get p2 from a Chinese retailer, most probably its rom should read P2a42. If that's the case, then there shouldn't be any problem with flashing roms related to P2a42, right?
Please shed some light on this if you can. :good:
Waiting eagerly for some news as well

For outside country they change into international Rom P2a42 so your right there is no problem with related rom
I'll explain the hardware differences between p2a42 and p2c72 and really hope this will end these questions that I see in every thread.
The difference is only in the ram, storage and 3g/4g bands.

Storage: 32GB
Cellular networks:
GSM: GSM850/ GSM900/ GSM1800/ GSM1900
3G: UMTS2100 (B1)/ UMTS1900 (B2)/ UMTS850 (B5)/ UMTS900 (B8)

https://forum.xda-developers.com/lenovo-p2/how-to/stock-rom-t3552973 I flash this rom on P2c72 ,all function works well, maybe you need ss to activation the Google Account
You can flash every rom available for p2a42 on p2c72, just edit the updater-script removing the assert get prop lines in the beginning.
These two phones has different bands but their roms works at each other.So just remove getprop line from the updater-script and flash the rom.
can someone please explain how to remove getprop line from the updater-script and flash the rom.
I bought the P2c72 from china and updated it to: V3.5_1652_5.1342.1_ST_p2c72.
Thanks

I have removed this from updater-script
Code:
getprop("ro.product.device") == "P2a42" || abort("E3004: This package is for \"P2a42\" devices; this is a \"" + getprop("ro.product.device") + "\".");
however i used System Update App then looked for my modified zip. fails at verification of the zip file.
Hi,
I'm buying a p2c72. I just wanted to confirm that the following will work after changing to the p2a42 rom?
a) I can unlock bootloader
b) I can install TWRP
c) I can install any p2a42 custom ROM (after removing the get-prop line)
Has anyone on the p2c72 had any problems rooting and flashing so far?
Asking also if I buy p2c72 (I don't need b20) can I install official European ROM on it and get automatic updates after that?
I've just received my P2C72.
1) It was updated to p2a42 by the seller so I didn't need to do anything in that regard.
2) I've just requested bootloader unlock, so I have to wait 14 days.
3) I did not need chinese phone number to request bootloader unlock.
Once I have the bootloader unlocked, I'll proceed to install TWRP, gain root, and flash a custom ROM.
I'll update here once I've done those so that future p2c72 users can benefit. You'll hear back from me in 2-3 weeks.
Update on p2c72 custom roms.
I've gotten bootloader unlock. It was quite easy.
1) I've installed TWRP 3.1.1.0. It works without any problems.
- please note that after booting into TWRP through fastboot, I realized that the stock recovery was still installed.
- if that happens for you, take an extra step of transferring the TWRP img into teh phone and installing the img using TWRP.
2) Not working: I've tried Resurrection Remix v5.8.3, Lineage OS 14.1, and AICP 12.1. All of these don't work. with RR and Lineage I only get a blank screen and the notification LED burns blue. With AICP, I get the bootscreen but it doesn't progress any further.
3)Working: Lineage OS 13.0 works.
- This may be related to the fact that I started wit ha stock marshmallow ROM. It seems only the marshmallow Lineage 13.0 is working so far.
Good luck to other p2c72 users. If you have any roms that worked for you, please update here for the others to benefit from. Thanks.

Ya.. i have the same P2c72 running on P2a42 stock MM.. upgraded to Nougat S233 and at first i was afraid that things may not work after bootloader unlocked...But with the newest TWRP 3.1.1.0 worked for me. I remember that i used another version of TWRP, and for certain none of the Roms worked.. until using the pre-official 3.1.1.0 that is official now.
Can flash whatever Rom with out problem. I'm on Stock Nougat Deodexed S233 and staying with it for a while. :good:

Thanks for the info Wmateria. That's good to know that you can flash all roms.
After messing around and flashing other roms a few times, somehow resurrection remix works for me now.
Unfortunately I'm not sure what I did to allow that to happen.
At least now there are 2 users (Wmateria and me) who can flash custom roms meant for p2a42.
I should note that I haven't changed the roms in any way (haven't removed the assert get prop line either).
I'll update again if anything else develops.

@Billytromp is also another one too. He was the one i asked about if it was safe to use the device to flash.
I've recently purchased a Lenovo p2c72. I'm entirely new to custom roms and Android Tinkering, but I really want to make my phone feel like it's not Chinese phone. I've kinda got the gist or basics on how to flash custom roms, but I have a few questions:
1. Will I be able to install future Android updates with a custom rom?
2. Will the installation be straightforward (download rom>install recovery>install rom>end)? Cos I read in the thread that you need bootloader unlock to install TWRP which I assume is a recovery app of some sort.
3. By installing a custom rom, will it include the various Google apps preinstalled in other non-Chinese phones?
Thank you.
@Wmateria. I saw @Billytromp's posts in the TWRP thread saying it went fine which gave me courage to flash TWRP. I also saw some of his posts where he got the black screen with blue LED with some ROMs. If we can gatehr a few more members and more info, maybe we can make a guide thread.
@bl00dsoaked. If you just put in a non-china sim into the phone and boot it, they say that the phone will auto download the p2a42 global rom and change it. This way you have the english version (except for band 20 for 4G) and it can also get future updates easily. Google apps should also be auto installed.
If for some reason that doesn't happen for you, there should be a way to flash the english version without unlocking bootloader or getting root. It uses adb but I've never done it myself.

Unfortunately this doesn't work. Unless there's some other tinkering I had to do other than just putting a sim in?
Sorry, what's adb?

4G you say? Like the american 4G or Europe 4G?
Got a good deal on a moto z2 force (with 3 moto mod accessories, so had to snap it up) - From Vodafone UK
Question about Oreo updates on this phone. Does not exist yet as I believe it is down to the carrier and networks to finalise, test and release, hence the delays.
I am aware that there are quite a few oreo firmware for retail models. (Although none exist yet for XT1789-06?) I have already unlocked the bootloader and I wanted to update to the recent ones. What I am worried about is the IMEI baseband. Anyone had success with this specific model (06)?
There's root, su ,magisk and xposed on this thread thanks to enetec.
https://forum.xda-developers.com/z2...w-to-safely-blunlock-twrp-root-t3704596/page1
Have not seen any oreo related updates, I did read on another thread that the t-mobile Oreo update was pulled because it was having issues with calls I think so maybe our version they are having the same issues. Have not even found a flash all file for our device so one a bit hesitant about even trying any other Rom.
Official bootable and flashable twrp works on nougat. Sprint wasn't on Oreo until late Feb z so I have used the first iteration on my phone before the Oreo OTA. It will have decryption support which is advised compared to encryption not working. That's a huge security risk. I'd suggest using official twrp and magisk if you want root. That way you keep encryption.

Hi there updated mine to Oreo with the file in this link https://mirrors.lolinet.com/firmware/moto/nash/official/RETAIL just follow the instructions in the link In post 2 on this thread, I'm pretty sure you can skip the unlocking bootloader (unless you want root as I do)
No, the above is no good for my carrier/phone (Vodaphone UK) Results in wifi and modem not working. Also 3 sparse files are missing. Used a US based USC Oreo rom and works perfectly now however

I had the the wifi problem when i flashed twrp (but still had network), then flashed the rom in my last post I am also on the uk vodafone model. could you post a link to the rom you flashed please.
It was this one https://androidfilehost.com/?fid=962187416754473797
It did give error in regards to the bootloader writing (and timed out - so did not overwrite bootloader) - I already have bootloader unlocked and was on Nougat when I recieved the phone. After updating to oreo, however with the exception of the carrier logo during boot, I have found no issues whatsoever with this rom on a Vodafone XT1789-06 UK model device. I also uninstalled or disabled US based applications / carrier bloat.
Everything works fine (Moto mods, Wifi, network, camera, 3d acceleration) etc
(Note, ignore the fact that the download is from the MotoZ2 play folder, there was no new directory for Z2 Force according to the uploader)
Cheers for the link already had this file downloaded but didn't flash it as I noticed it was a us Version. there was a update at 19:30 on the link I posted but have not flashed it yet, no bloatware on this rom just plain stock and all mods work will flash the update sometime over the weekend and let you know how it goes.
I tried the newer version recently and same issue (no wifi or modem), so reverted back to USC version
Hello guys i also have the z2 force on UK Vodafone and looking for a 8.0 update. Did you guys find one that completely works? i dont want to unlock the bootloader or root (stops my bank app).
Any news on this please?

Unlocking bootloader doesn't stop Banking apps but root will, I have an unlocked bootloader and on the xt1789-06 Vodafone UK running stock ROM from the link I posted above got both nationwide and Barclays apps and both run fine if you flash the first n version it will do all the seamless updates, it just seems Vodafone are a bit slow at pushing them.
I'd love to settle once and for all the issues with Verizon modems or whatever on custom ROMS, the issue being that you MUST place a phone call after reboots and periodical hibernation to receive texts, voicemail and MMS.
I don't know squat about editing ROMs or the like, but I wish I did. I'm here to try to establish a collaborative effort to fix this issue. I really love my LGV30, and I purchased it because I could root it. Custom ROMs are great, but to be honest it can be risky to not receive messages.

Have you tried running stock lg? In my experience they have less issues than custom roms.
Also now that your phone has an unlocked bootloader, you may be able to flash your phone back to verizon vs996 and still retain root and unlocked bootloader.
Does the stock us998 firmware cover all of the bands for verizon?
Did you try and change the bearer from global to cdma/lte?
I used stock for a spell. Things worked rather well. Tried switching network type to no avail.

There is a stock vs996 rom that you can flash with twrp and root/keep unlocked bootloader.
May be worth looking into.
I tried this. The overall objective of the thread is to not keep root on stock, but to provide or find ways to have a reliable Verizon network on a custom ROM
A notable piece of evidence is that DOTOS works fine, at least it has for me. @Stuckurface on page 34 of the LOS 8.1 rom page seemed to have a good lead.
I don't know how to attack this problem, but I can follow instructions if a dev would like me to try anything or provide information...

I'm getting lost in a lot of the information in here.
I'm fed up with lousy performance and charging my phone 2-3 times per day. I've read a few posts online about how the Exynos version is to blame (lucky me, that's the one I have), and that there are some minor tweaks I can do to both improve the performance and battery life.
However, I am dependent on VoLTE and being able to mask root access (actually, I don't really need root access, I just want to change the CPU settings, which I assume requires root access).
From what I've read none of the AOSP ROMs supports VoLTE, and the Lineage crew says it's impossible for them to support it, while other ROMs says that "everything works" which I would think includes VoLTE.
So to the point. I need to keep VoLTE, and I need to be able to mask root. Is it possible to retain those while:
1) Being able to mod CPU settings
2) Being able to uninstall Samsung (cr)apps
3) Getting a clean android experience without any Samsung customization
Device: SM-G960F
Many thanks.
Im on Soliders ROM, very very good ROM.
I have WiFi calling working, but I have to contact my provider and ask for the config file to be OTA sent to me (only if I full wipe on setup)
I have VoLTE, but it doenst work or activate. Not sure its every worked.

Awesome, but now I have a new question. What does bri4 mean? I see BRI1, BRI3 and BRI4 for some ROMs, does that have something to do with which version of the device I have?
BRI4, its just the latest release basically.
Can check in settings>about>software to see your version and work from there
I am really interested in using my P6P which is sitting for months in my drawer, because I am unable to use VoLTE/VoWIFI in my country (Slovakia). This is crucial to me and to my work. I don't care that much about 5G as coverage is big enough.
I have been reading some articles and threads, but I don't have the crucial questions answered, so I will give it a try here:
1. Do I need to root device to enable the two options I am asking in first place?
2. If I will root it, will I be able to use the Company Portal, Gpay and banking apps?
3. Can I update new versions of Android when my phone is rooted? I assume it would have to be done via sideload not via OTA.
4. Can anyone point me to proper thread which will lead me through the process in achieving all this successfuly?
Thank you.
There's a custom with custom avb key (this means you can relock bootloader after Rom install) that has VoLTE tweak enabled for unsupported country within the Rom. 5G is also tweaked to be enabled.
And after that, future update is via sideloading in recovery mode, no need to re-unlock bootloader
Go check out the Rom in telegram here https://t.me/hentaiOSRaviole
That seems like custom ROM - I am not really interested in that. I prefer it as stock as possible.
I only found this.But it's only for Chinese ISP(and it works fine for me) . It's a magisk module which modify mbn_sw.txt to enable VoLTE for Chinese Operators .
GitHub - CHN-MuXin/MagiskModuleEnableChinaForVoTELtoPIxel: This module will modify mbn_sw.txt to enable VoLTE for Chinese Operators . Theoretical support for all Pixel models and Android versions

Yup. Custom ROM but no additional features like other custom ROM. Their aim is just to improve the stock ROM.
