[GUIDE] Changing p2c72 to p2a42 and flashing custom ROMs

There are currently 2 variants of the Lenovo P2, p2a42 (32GB, global version) and p2c72 (64GB, china version).
The p2c72 is slightly different, enough to cause confusion among people who have just bought it.
There are a few scattered threads asking about the p2c72. This thread aims to bring together all that info.
It will also list down which ROMs are safe to flash for the p2c72 without bootloop.
Changing p2c72 to the p2a42 (english) ROM.
Yes, this is possible and easily done. Bootloader unlock is not needed.
a) If you're lucky, the seller will have changed the ROM for you to p2a42. (Confirmed to be true with all Gearbest and Banggood purchases. I recommend you just purchase from here. Don't forget to use vouchers.)
b) If the phone you get still has the p2c72 ROM, try placing a non-china sim and rebooting. It will ask you to update and then reboot. You should now have the p2a42 ROM.
c) If (b) doesn't work, you will have to flash the p2a42 ROM through lenovo stock recovery: (this is based on the experience of lmcdermo)
1) Download the nougat TWRP file from http://www.stechguide.com/install-android-7-0-nougat-firmware-on-lenovo-p2/
2) Save it on your phone (internal sd card) as update.zip
3) Power off your phone. Boot into recovery by holding down "Volume Up + Power Button". The moment it boots, keep holding "Volume Up" but release "Power Button".
4) It should now boot to lenovo stock recovery
5) Click "Install Update Package" and select "update.zip"
6) Wait a few minutes for it to finish installing. When done, reboot.
7) If there are any issues, go back to recovery and wipe cache.​
d) If (c) still doesn't work, you will have to flash the p2a42 ROM through fastboot. Be advised that numerous users without bootloader unlock have mentioned that this method gives bootloops. However, it should work fine for those with bootloader unlock to unbrick their phones.
1) Download the stock ROM file http://www.mediafire.com/file/mm9b6hlwbaxpdnj/P2a42_S048_161111_ROW_fastboot_Lodd.7z and extract it. It includes minimal adb and drivers.
2) Install minimal ADB and fastboot.
3) Install all 3 drivers (outside of the SW folder).
4) Then move all the files in folder SW to the minimal adb folder. It should be at 'C:\Program Files (X86)\Minimal ADB and Fastboot'.
5) Power off your phone. Boot into fastboot by holding down "Volume Down + Power Button". Connect phone to computer.
6) Run minimal adb and type 'fastboot devices' to confirm it's connected.
7) Then type 'flashall'. This will run the included flashall.bat file (which you copied over from the SW folder)
8) Wait a few minutes for it to finish flashing. When done, type 'fastboot reboot'​
Unlocking Bootloader & Installing TWRP
You can install TWRP the same way as you would for a p2a42 phone.
celoxocis said:
Team Win Recovery Project 3.1.1-1
[*]Extract/ install adb & fastboot to your computer.
[*]Download TWRP for Lenovo P2 (P2a42).
[*]In your ROM, go to Settings -> About device. Tap 8 times on Build number to enable Developer options.
[*]Now go to Settings -> Developer options. (above About device)
You need to enable OEM unlock, otherwise you might end up with boot problems or be unable to flash later on.
Once you tap the unlock the bootloader it will ask you to formally submit the request, when you accepted the void warranty thing you will have to wait 14 days.
[*] After 14 days . Reboot your device into fastboot mode. To do this, select reboot from the power menu and hold the [Volume Down] + [Power] buttons while your device reboots or boots from power off.
[*]Once you're in fastboot mode, you need to unlock your bootloader. To do this, run this command:
fastboot oem unlock
WARNING: Unlocking your bootloader will erase all userdata on the device! Your device will be completely reset to factory defaults!
[*]Once your bootloader is unlocked, you're ready to flash TWRP. To do this, run these commands in order:
fastboot flash recovery twrp.img
fastboot boot twrp.img
[*]At this point, you will reach the screen asking you if you want to allow system modifications.
By swiping right, you will trigger system modifications for TWRP and TWRP will be installed permanently!
If you are going to root your device and follow the rest of these steps, then it is safe to swipe right and enable modifications.
[*]If your device asks for a password to mount internal storage, and your password doesn't work or you haven't set one, see below under known issues for a fix!

Getting Root
(to be expanded..)
You can obtain root the same way as you would for a p2a42 phone.
1) From TWRP change File System of the "data" partition to EXT4 format
2) Download either supersu or magisk. Install.
3) Boot your ROM and install SuperSU or Magisk Manager (respectively)
Safe ROMs to flash
1. TWRP v3.1.1-0 (not a ROM, but important to have)
2. Lineage OS 14.1
3. Resurrection Remix v5.8.3
ROMs above verified by me. Wmateria and Billytromp have also gotten TWRP and custom ROMs to work on p2c72.
This will be updated as we go.
Edit: Added method to flash p2a42 from stock recovery. Fastboot method has been reported to cause bootloops when bootloader is locked.

i will test it when i will receive my P2c72 phone from banggood.
gearbest is selling a p2a42 version with 64gb and without band 20. SO I SUPPOSE they are declaring a FALSE information, writing p2a42 because i 've never seen a p2a42 with 64gb !!!
the most important thing to me is to flash resurrection rom.. i love it and i NEED IT

Banggood are doing an offer on p2, 172.28 with code lenovop2, in case anybody is interested.

Does the global version have any extra bands or something? I'm asking because I live in the US, and I'm going to buy one the the china models.

Damn, that's really nice. Just tested it out at checkout and can confirm the code still works. I paid 270 for mine, so this is 30% cheaper.
Edit: Just found out that Gearbest is also doing a flash sale. £177, 5 pounds higher, but they have stock and will ship immediately. Banggood is on preorder. If anyone is interested.

As far as I know the main difference is that global has band 20 for 4G. I don't know if your network provider uses that for 4G, you'll have to check. For myself, it doesn't make a difference as I always turn off 4G and use 3G anyway. The other difference is that the global version only has a max 32GB of storage (unless you add an external sd card). Those are the only differences I'm aware of. In my opinion it's worth buying the china version for the extra internal storage.

What a great source of useful information here, thanks.
I am looking at buying the P2 64GB C72 Version, I am attracted by the higher memory and much lower price.
I would like to modify to get Band 28 for 700Mhz, one of our 4G bands in Oz.
Can you just confirm, again......, 'once more for the dummies', that access to the extra global bands is the only difference.
And, also that a person with good comprehension and logic skills would be able to perform the modification that you have created.

Hi just some info for you i am also quite a fan of the RR rom i have used it on other phones but on the p2 their are a few things that might make you not like it. 1 the earpiece vol is quite low compared to stock rom and becomes annoying after a while. 2 Although fingerprint unlock works fine the fingerprint gestures will not work for going back etc.. and 3 Volte iff you require that does not work either. All of the above bugs are present in all the custom roms available to date for the P2 because i have tried them all and decided to go back to stock deodexed rom on which everything works. Hopefully i will save you some time. As far as the phone goes it is an excellent phone in every aspect.

P2C72 Bootloader unlock user ，failed can not start the card white screen

i received my p2c72 from banggood but the software shows p2a42...... i think they flashed it manually.
But the strange thing is that it's on MM an does not find any OTA.......

I'm waiting for another P2 from Banggood.
If you investigate how to upgrade to version 7.0, please write it.
Maybe they have not flashed the original ROM ROW and what they have done is manipulate the chinese ROM.

You can either continue trying to get the OTA update or you can download the Nougat ROM and flash the system, boot, recovery images using fastboot.
Try playing a couple of videos from you local storage and from youtube and see if the audio and video are not in sync. If audio/video are in sync, I don't see what you need to bother to get Nougat. Nougat and MM are almost identical from a user's perspective.

do u also have a c72 hardware arrived flashed with a42 software?
i don't know hot to start modding this phone... should i use this twrp ? https://forum.xda-developers.com/le...covery-unofficial-twrp-lenovo-p2-3-0-t3533659
i've read that this recovery is JUST FOR A42 phone..... is it true? i only need to flash a twrp then i am able to choose a custom rom and flash it, it is easy.

My phone was bought in the Uk at 3 shop with p2a42 international software it is the 32gb variant. I believe you need to first convert the rom to the p2a42 variant their are guides on this forum on how to do that and then u can flash a recovery and root etc.

Do you want to update to official Nougat or do you want to install custom ROMS ?
1. If you want to install official Nougat, follow this.
2. If you want to run custom ROMs, you need to unlock your bootloader first. This process takes 14 days.

i want a custom rom, ok i will wait 14 days i see the countdown on my phone... but the more risky part is to flash THE RIGHT TWRP for my c72 hardware ( but with a42 software inside). i've read that the twrp here on xda is ONLY for a42...... so what should c72 users flash?

That's why I stopped responding to him.

I've ordered my P2 from Gearbest (for 185€) and today upon receiving the unit I got a nice surprise.
As we all know (and is stated on the product page) they are selling the p2c72 with the p2a42 software. They say that it cannot be updated to nougat but that is incorrect.
As soon as the first boot it prompts a OTA upgrade within Marshmallow (S048 to S062) and after rebooting it shows the OTA upgrade to Nougat (S233) and after a quite fast upgrade (90 seconds?) it shows another OTA (this time to s244).
I thought I had to manually do the upgrade https://forum.xda-developers.com/lenovo-p2/how-to/guide-upgrade-p2c72-a42-to-nougat-ver-t3653596 before receiving the phone.
This is without a doubt a p2c72 (stated on the back sticker and the front sticker has plenty of Chinese ). Has anyone had this luck before?

Almost everyone that buys a c72 comes with a a42 firmware when they buy from Banggood, GearBest, and alibaba.
When did you buy it because I don't see the price at 185€ today?

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.

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.

There is an option to install google play store, but that would make your rom unable to receive updates.

please Help - Stuck in recovery Bootloop after downgrade from MIUI 12 V12.1.4.0.RFDEUXM to MIUI 12 V12.1.3.0.RFDEUXM via update app

Hello Android-Wizzards,
i am stuck in a Bootloop to stock recovery mode since i tried to downgrade my mi note 10 pro from MIUI 12 V12.1.4.0.RFDEUXM to MIUI 12 V12.1.3.0.RFDEUXM via the update app .
After the OTA update to 12.1.4. i could not make any calls anymore so i searched for a way to downgrade to 12.1.3, where the problem was not present. I did it with the internal update app and followed this instruction: https://www.world-today-news.com/th...evert-your-xiaomi-a-buggy-update-xiaomi-news/
Sadly i didnt make a backup before anf after the rom finished installing it only boots to stock recovery anymore. If i try to connect the device via "Connect with MIAssistant" it does not work.
I searched the forums but i cant find a way to install MIUI 12 V12.1.4.0.RFDEUXM again.
The tutorials mention that if i want to recover my phone i have to use MIflash or fastboot flash which both need a unlocked bootloader according to the tutorials.
Sadly i did NOT unlock the bootloader when the phone was working normal and i dont see a method to umlock the bootloader an a bricked / bottloped mi note 10 pro.
Its bad enough that cause i didnt make a backup befor i tried to downgrad i must assume that all my pbhotos i took this year with my note 10 pro are lost forever, Mi cloud backup is full since last year and i didnt bother to pay for more space, another bad decicion in hindsight but is there a way i can restore my phone?
Please help, i dunno what else to do to get my phone booting up agian.
Had a simmilar problem with an older mi phone of mine a few years ago and then it wasnt a problem cause i could easyli flash it with MIflash, but dunno since when you have to unlock bootloader first and since i didnt know that my phone has a locked bootloader, never minded to unlock it.

Did you try wipe data with the recovery?
or try this old method.

Did you try to flash the rom in recovery again?

Question Stuck on Oneplus 9 Pro Indian firmware

I attempted to convert my t-mobile oneplus 9 to international firmware by first flashing the Indian firmware.
I mistakenly downloaded the oneplus 9 PRO Indian msm.
I didn't realize this as the file has a very similar name. Lemonade_22.I.07_210412 vs Lemonadep_22_I.07_210412
I've tried everything since then, with no success. I tried to flash the correct oneplus 9 indian msm but it says incorrect device.
So I'm stuck with the oneplus 9 pro Indian firmware and can't get back to indian oneplus 9 firmware....

I have been developing and flashing android devices since the early days of Cyanogenmod... dozens of devices. And guess what? I did EXACTLY the same thing as you.
The link I downloaded from said it was Oneplus 9 firmware, and given the filenames being virtually identical, I never noticed it was the Oneplus 9 PRO firmware.
So don't feel too bad. Even experienced people can make mistakes when trying to flash phones!
I am working on a solution, but so far no luck because:
1. Msm Tool will not flash the Oneplus 9 firmware as it thinks it is the incorrect device (why did it let us flash the incorrect device firmware before???)
2. The bootloader is re-locked and the OEM Unlocking feature is greyed out in Developer options, therefore fastboot can't be used to re-flash the correct firmware.
3. The System Update "local upgrade" feature does not find ZIP files in the root folder and will not allow us to browse to the correct file.
So for now, we are stuck. I think solving #3 will be the solution. If we can make the "local upgrade" work, we should be able to flash the stock firmware ZIP.

@Derek6091 @mightysween did you fix it yet? I had my device screw up so bad today that the only MSM I could use on my global unit was the Indian 9 Pro firmware and I have gotten my device mostly working.
You can see my drama with it and how I finally got it working here.
[SOLVED] Can anyone help me unbrick? I have tried lite firehose, MSM for global, MSM for Indian 9 Pro, none work
I modded the global MSM so that it will flash to this frankenphone. https://forum.xda-developers.com/t/all-of-those-stuck-on-indian-firmware-rejoice-i-modded-the-global-msm.4442473/ EDIT: For anyone else trying this and getting unsupported...

I can get it working with 11.2.10.10 but not OOS 12, in OOS 12 the touchscreen doesn't work and it shows dual SIM icons so it's still doing something that makes it think it's a foreign variant. I ended up just going back to StagOS where I was before everything got mucked up.
Unfortunately the MSMs still see it as an Indian variant so I can only flash the Indian OP9P firmware to it, tried all the other MSMs and none work. I have been reading threads here and people claim they got it back to global but I tried all of the suggestions and none of them restored the device enough to where the global MSM Tool didn't see it as an Indian model and refuse to flash so I think we are stuck with this frankendevice.

@EtherealRemnant Yes I had to do oem unlock while on the Indian firmware. If your phone has the oem unlock greyed out, there's a guide on how to fix that with a simple command line.
Then I unlocked bootloader, flashed lineage recovery then a custom ROM. Haven't tried to get back to stock rom, and I don't think we can.... But I love this rom I'm currently on which is stagos.

Go to your home screen on your phone and connect to computer with usb debugging and run this command in cmd,
adb shell pm disable-user com.qualcomm.qti.uim
Then go to developer options and oem unlock should be able to toggle.

You have to use the Oppo Decrypter tools. Decrypt the OPS file and open settings.xml. At the bottom of it there's a Target area. I just edited that to IN instead of O2 and re-packed it.

I tried it with the T-Mobile MSM but it still failed on "unsupported target". Did you only change the text value for O2 to IN, or did you need to change the numerical Target ID as well?
I am pretty content leaving this phone on StagOS anyway, but would be nice to figure out a way to return to T-Mobile stock after recovering from a brick.

Manually flashing partitions in Fastboot does work, FYI. So it is possible to go back to stock that way once the bootoader is re-unlocked.
I wonder where the "target" data is stored on the actual device. If it is simply a numerical/text value in an accessible partition, seems like it would be pretty easy to make a TWRP flashable that can change it.

Strange that it didn't work for you. That was indeed all I changed. Did you change it to what the unsupported target message said your device was? I was comparing the settings between India and global and besides the change of target ID, the target number on India was 3 instead of 1. No idea if that makes a difference though because I didn't try it.
You made sure to re-encrypt and replace the OPS, right?
Also yeah you can flash with fastboot, it doesn't fix that flag though and when I tried to go back to OOS 12 with the messed up flag it thought my device was a dual SIM device so there was no signal and the touchscreen didn't work. Happened twice. With the modified MSM I went back to global and am running OOS 12 right now.

All you have to do to go back to global is download the full OTA for your device and flash it with the system updater.

Then use the downgrade package. It will wipe your phone again but I will get you back to full OOS11 firmware and that issue won't happen.

downgrade indian version 11.2.5.5 , unfortunately it just tells me it cannot read the file when i attempt to sideload

Cannot upgrade to 12.5 MIUI

I have a Russian (thanks Amazon !!) Redmi 9a 32Gb/2gb. It is currently running latest 12.0.x ROM version, but i would like to upgrade it to 12.5.
I see on xiaomi ROM site there is currently a 12.5.x version for Russian version, but the OTA never arrived and if i download the recovery zip file and install it manually, it fails verification and stops.
Is there a way to install 12.5 without unlocking the bootloader ?
Is 12.5 supported on this specific redmi 9a ?
thanks !

mmm... spflashtool might work, but Ive only ever used it on a bircked device to unbrick it, never on a functional device to just change the ROM version, but if you really wanna do it without unlocking bootloader thats your best choice.
I will say anyway, its probably safer to unlock bootloader install recovery and install the rom from there, its your call tho.
Heres how I unbricked my device

Thanks
Right now I cannot unlock the bootloader, maybe in the next months I might try (I want to wait for the warranty to expire). My concern is that my version of Redmi 9A with just 2G of Ram is actually not compatible with MIUI 12.5. The 12.5 rom is actually available, but OTA will leave me in the 12.0 branch and verification fails if I try to install the ROM manually. I would not want to brick it by installing an unsupported ROM.

My phone model is M2006C3LG and the ROM I have right now says I have 1.8Gb of available RAM, I don't think you have a different device from mine.
Im a total n00b so I may be wrong about this next thing, but, I think the only difference is what version of MIUI they were sold with since the hardware doesn't allow downgrades further than the stock ROM that came with the device.
There is always antirollback after MIUI 10, but I think its even further locked for the original stock ROM that came to the device, but yeah, this is all my own speculation due to a bricking incident I faced.

The model number is the same, but the 9A was available with different sizes of RAM 2 or 3 or 4 Gb. Mine is the low end 32/2 which is the model still on sale today. If you still have 1.8 Gb of free RAM you very likely has the 3 or 4 GB model.
Maybe you are right, the OTA allows only for updates within the same MIUi version; I saw several guides on-line and i think i will try the miflash tool and switch to the global version. I have to find a way to unlock bootloader without Xiaomi account (no way in hell I'm signing up for that) and without sim card (this phone is used as a smaller wi-fi only tablet). There are some tools for an offline unlock, I will try those first.
It is incredible how Xiaomi is making it complex just to update to a stable official ROM; given also how much bloatware is shovelled with the stock ROM, I'm not sure I will ever consider Xiaomi again.

In my opinion, DON'T UPGRADE. I upgraded it with recovery and fastboot and my phone got an message everytime when I boot it : dm verity corrupted and I will need to press power button again to work. Maybe i didn't did that correctly ( I have Global 12.0.20 32/2gb)

Thanks for the info. So you upgraded to latest 12.0 without moving to 12.5, any reason for not trying 12.5 ? The phone is currently barely usable with Android 10, maybe Android 11 is even heavier, but why not give it a try ?
I saw several youtube videos and guides and by using MI Flash with a Fastboot image (scattered tgz) it should be a total reflash of the phone.
