[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.

Question T-mobile oneplus 9 (LE2117) has an unlocked bootloader now?

Hello all, after lurking here for a while, I found something that's making me post.
I have a carrier locked OP9. I just received the update to Android 12, and it has broken critical features. (Particularly not being able to stop apps from being closed accidentally!)
I have looked at Lineage OS in the past, and the process to get the LE2117's bootloader unlocked was... complicated.
However, while trying to fix other problems, rooting around in the developer options, I noticed that "unlock bootloader" was actually toggleable!
I think I have an unlocked bootloader now, but it's on android 12, and all the guides for rooting and installing a custom MOD for this phone say you must revert to android 11 before anything else.
So what now? Am I waiting for lineageOS 19 to come out, because that's the one based on android 12? I'm new to custom roms, and don't get the coding side of how all this works. (But I'm pretty determined to figure this out.)
Thanks for any help or advice you've got!

each stock update has a new firmware right now atleast all the roms are based on a11 latest firmware im not sure since oneplus got a12 if roms will switch to the newer firmware here is to hoping!

Gotcha, thanks. So waiting for lineage 19 it is, it sounds like, since that one is based off android 12.

I am pretty sure there is root for 12. All you need to do is dump the payload from the 12 update OnePlus let's loose, and patch it with magisk and flash it via fastboot. Via bootloader it is easy I am using a TMobile OnePlus 9. All you need to do is revert back to 11 via a msm tool. There is a post here for that. After downgrading to unlock your bootloader is easy only takes time. There is a post for it I don't remember all the details but all you have to do is get you imei code and email OnePlus. Soon they will sent you a code to fastboot flash to unlock the bootloader. After that most of these 12 work for us on our model phone. I am using evolution x. It tells me every day I can go to 12 .

Yes yes they do.

I've run into this same issue with wanting to use a Custom ROM. I have the T-Mobile version on A12 and it's now rooted. Another user shared the patched image file with me. I flashed it with fastboot boot boot.img then direct installed through Magisk to gain root. But all the custom roms here require A11 downgrade through the MSM tool and you have to use an MSM tool for T-Mobile, which was shared with me and explained but I'm not willing to downgrade. Until a custom ROM releases that I can flash on top of A12 I won't use it. I've had bad experiences with MSM tool to recover from brick and didn't succeed and had to send back to OnePlus for repair.

It amazes me how many people have problems with the MSM Tool. I was afraid I was going to have problems after reading all the issues people have had and had zero and I've used it twice. Both times I just put the phone in EDL and connected it to the USB-C port on my tower. Windows 11 surprisingly didn't even give me any issues.

What worked for me was shutting the phone off, removing my case, holding both volume up and down, then plugging the phone in. The screen won't show anything, you have to look at the MSM Tool and see that it's connected to know you did it right. Both times I tried it worked perfectly.
You can also use adb reboot edl if you can get the thing to boot and have USB debugging turned on.

android version: 10
software version: tb-_706f_rf01_201229
ROM: TB-J706F_S240073_201229_ROW
kernel: 4.14.117 from 2020
Widevine: L1
And I whant to update to TB-J706F_S620150_211226_ROW. So my questions are many
-Can i use lenovo sofware to update?
-Do i need to lock or unlock oem bootloader from settings?
-Can only be done using QFIL or other softwares?
-Do i need to find out if it's region lock?
-How to backup this img, if everything goes wrong?
-Do i have to install the original chinese version, or can i just update the international one?
I see alot of threats talking about going from international to chinese, but I like to have play store and keepping widevine lv.1. Without having to do a lot of "work".
I've tried to use the OTA function, but downloads the update (just after my current version) it restart's and gets to the lenovo logo on the screen and reboots. Like a boot loop. I've to manually shutdown the tablet and it's back to normal.
After readding this forum, i still dont see a uniform way to update this device, and more importantly a easy way to do it. Can all of you help me?

- yes
- no
- yes
- even CN versions can be flashed with global rom
- you could still flash an img you download online if something wrongs happen
- it's on your own, if you have L1 with global unless you want latest updates no need to go CN, stay global.
if OTA update doesn't work maybe reset the device or even flash the newest rom available from lolinet then update with OTA.

@melones22 Thanks for the aswers.
Do you know if i download the newest global rom from lolinet, and force install, if i keep my lv1?

if you relock bootloader, likely. personally with natsafety patch + hde etc still l3
be absolute sure that you didn’t modified anything else than flashing before relocking

If you flash stock ROMs CN or Global you do NOT need to unlock bootloader

To flash a ROM you can use QFIL, I never used Lenovo softwaare so I am not sure if you can flash form there only last version or if you have a choice.
Normally you should not be required to use QFIL and you should be able to update with OTA updates.

If you are having problems updating I guess it doesn't hurt finding that out.

You should backup QCN with QFIL and all partitions (you can probably exclude vendor and userdata) with QFIL or edl, there is a guide for both methods (I use edl) https://forum.xda-developers.com/t/two-ways-to-backup-tb-j706f-without-unlocking-bootloader.4402799/

You should be able to update your global ROM but since you are having problems I don't exclude you might need to go back to CN ROM before flashing again the Global ROM.

I am not sure what's the problem with your OTA update.
I would suggest to:
Backup your QCN and all partitions first
Open your QCN with QCNView and check the region in NV Item 6858
If your region is 02 is Global and OTA update should work, so maybe try a factory reset and see if after OTA update works.
If it's 00 (region unlocked) or 01 (China) that might be the reason OTA updates are not working.
Edit
I read again the version you have now and it's quite old, that probably does not have any region lock.
In the one tablet I had from the shop with Chinese ROM I flashed TB-J706F_S250260_210804_ROW, that set it as global region and then from that I run OTA updates.
So I think you should backup as I said before and then flash TB-J706F_S250260_210804_ROW, make sure to select the right settings in QFIL and NEVER check "Reset state machine".

Hi Mr. Crayon,
Is there any guide in how to do as what you mentioned above ? I'm quite new to this 'manual update' and still learning. Would really appreciate your help on this. My Xiaoxin Pad Pro 2020 (TB-J706F_S268018_210731_ROW) is still running on android 10 and my device is not certified by play protect. T.T

Hello.
Thanks @MrCrayon, but i never has able to use qfil to backup my device. To complicated for me. But thanks for the help.
So what i did to update my tablet. After feeling the same way @shaoki92 , i just tried to use lenovo tools. And... puff... update done.
No problems what so ever,
Did not lose L1
And did not have to mess with bootloader or region lock.
But i understand that i took a big risk. The tablet could've become just a paper weight. But until now working fine. With new android and everything.

Hi front3,
May i ask how do you update using lenovo tools ? Thanks

Im no expert that so ever. But i can tell you that i did.
Install lenovo assistance, on windows.
Used the charging cable of the tablet to connect to pc.
Launch the app
Connect to the device via app
(And i dont remember now, but i think its recue my device, and update, inside the app)
The app gives you a warning about using the tool on CH devices, and i took the risk.
Check the firmware version that the app gives you, and what it the lastest that has been deploid. Just to be sure. And do it if you dont mind taking the risk, do it.
In my case, the version that the app recomended has not on lolinet at that time. It only show up there, weeks later. But because the app connects to lenovo servers directly, i think it was safe.
Be careful because you can brick the device. And like @MrCrayon explained, i had one very old firmware, so xiaoxin didnt have the same "security" feactures has the newer devices. So maybe that is why it worked.

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.
