Thanks for that and that great tool.

One more question, will that update do a factory reset? I plan to do the update from the phone directly, it offers me update 350MB.
[Huawei P9 Lite ROMs, Kernels, Recoveries, & Other ] k1ll3r8e:
Heyho,

- THX for the warm words ;) -

If u have the stock recovery installed u can try to install it on the mentioned way. If it fails (like by another user) u can still download the L21/L31 C432B151 and install the full update via "dload". (U need the stock recovery installed for this, u can flash it with the toolkit.)

About the factory-reset, the update it self will NOT cause a factory-reset but, when u need root and an unlocked bootloader the unlock will normally wipe the device. U can avoid that by following this post (Q:5).

Regards,

Sebastian

Does anyone know if any of this will work for the VNS-L23? I'd really like to enable dual sim. Mine is carrier unlocked, originally from TIGO (Latin America). Thanks!
[Huawei P9 Lite ROMs, Kernels, Recoveries, & Other ] k1ll3r8e:
Heyho,

currently i have no L23 Dual-Sim oeminfo, so the Dual-Sim part will not work on the L23. But the TWRP under "Recovery" will probably work. Also, if u get somewhere an oeminfo for the L23 u'll be able to flash it with the toolkit (Remember, u need also the correct firmware for the oeminfo).

Just want to thank the dev, and confirm this works on Croatian ISP VIPnet, tested on two P9 Lite phones, both VNS-L21 (2GB) models. Naturally, VIPnet support denies that their model can be unlocked, but it works just fine.

Also, here are two links that mostly work for the bootloader key:

http://www.emui.com/en/plugin.php?id=unlock&mod=detail

https://www.emui.com/en/plugin/unlock/index

These two links are in English, work, and only thing I have to warn is - they did not work in Chrome neither for me or a colleague. Using Microsoft Edge worked just fine, did not test other browsers.

Also, if anyone needs it, HiSuite is also available for direct download from http://consumer.huawei.com/minisite/HiSuite_en/index.html

It took me close to 4 hours to do it all, mostly because of the bootloader key (tried dozen links till I found these that work), and the "storage decryption". But other than that everything else was straightforward.

True. I have done the same, with a bit of hassle with USB drivers and having had to use two different PCs to get from single SIM to Dual SIM to have the device seen by ADB in fastboot mode, and both SIMs still work under EMUI 4.1.1/B150. However, I should have upgraded to B150 right away after flashing to Dual SIM ROM/B130, because now even having restored apps in HiSuite and Nova Launcher in B150 I have some manual work to do on settings of apps.

hello again.

i took the .zip file from your files, did as mentioned: checked the oem unlock and the usb debugging, copied the dload to the 0\ folder, flashed, and now i get vns-L21C900B130, i flashed it 4 times already, no change still L21C900B130.

any ideas?
[Huawei P9 Lite ROMs, Kernels, Recoveries, & Other ] SevenSlevin:
You need to unlock bootloader first using bootloader code that you can take from Huawei.

After that you need to install twrp recovery, root device, re-flash stock recovery, change oeminfo and custom.bin(probably you want VNS-L21C432 ) using the tool and following the guide in it.

In the end you need to install update.app using 3 bottons. This if you want to debrand your device.

If you want just update your device without debrand it, this is last update VNS-L21C02B123: Link

In this case you don't need to unlock bootloader, root, change oeminfo etc. You just need to install /sdcard/dload/update.app using 3 bottons from shutdown phone or project menu using dialer code: *#*#2846579#*#*

PS. VNS-L21C432B151 no brand is the same version of VNS-L21C02B123 of brand Vodafone, both update your phone in Emui 4.1.1 and have the same changelog.
[Huawei P9 Lite ROMs, Kernels, Recoveries, & Other ] niggaru:

Hello Sebastian,

I do NOT want to Root, flash rom

Do I need to unlock bootloader?

Thank you
[Huawei P9 Lite ROMs, Kernels, Recoveries, & Other ] LuxZg:
To unlock you will have to do all of that - unlock bootloader, flash rom, root, unlock dual sim, flash again, and if you want - upgrade OTA to latest version. But after last OTA upgrade your bootloader will be locked again, and root will be gone.

[Huawei P9 Lite ROMs, Kernels, Recoveries, & Other ] k1ll3r8e:
Heyho,

to enable Dual-Sim u need to flash the "EU oeminfo C432" so at least u need to upgrade to this firmware also. This is done by flashing it before u upgrade to Dual-Sim. This will end, before u flashed the oeminfo, in an C900. After u flashed the oeminfo u get the C432 and all is fine. (U can also receive updates via OTA.)

So at least the update to C432 without the matching oeminfo, which can be flashed with the toolkit, will always end in an C900. (This is no error it's absoulte normal in this process.)

Edit:

To enable Dual-Sim u need root rights on the device to write to the needed partition, so yes u need root for this step. After u flashed the C432 the last time, after u flashed the oeminfo, the bootloader will be locked and root will be removed. So u are on the "original stock" rom with Dual-Sim activated. - Dual-Sim will stay during OTA's and get not deleted or deactivated.

Hope this helps!

Regards,

Sebastian

Hey Balkrish999, I think the actual firmware is L31C900B132 (check system\hw_oem\VNS-L31\prop\local.prop) and somehow its changed to what is shown on System Settings. But I think you can just use the europe one and follow the guide on the forum to convert to dual sim. This is the firmware or newer one I will use when I decide to start from scratch. Personally, not interested in dual SIM as I would like to use the MicroSD card.
[Huawei P9 Lite ROMs, Kernels, Recoveries, & Other ] k1ll3r8e:
Heyho,

the latest versions are currently CxxxB150, CxxxB151 and CxxxB161. About the dual-sim, with a little bit hardware hacking u can use both sim-cards + the sd-card ;)

Regards,

Sebastian
[Huawei P9 Lite ROMs, Kernels, Recoveries, & Other ] buddimanv:
Thanks Sebastian,

Ok, just got curious about dual sim functionality, lol

Reviewed the thread and I think the procedure as below – high level summary:

1. Flash SINGLE SIM L31C432B130.zip/ VNS L31C432B151 or latest available firmware (and do OTA Update).

2. Minimum Backup: oeminfo & custom.bin (use SRKToolHuawei-STABLE-V1.3-20160619 or TWRP).

3. Flash Dual SIM oeminfo & custom.bin (link would be good)

To Revert back:

Flash oeminfo & custom.bin from backups or single sim phone (and it will convert to single sim).

Can you confirm or make changes, ideally with some link – will start playing now :)
[Huawei P9 Lite ROMs, Kernels, Recoveries, & Other ] k1ll3r8e:
Heyho,

yup that's right.

1. Flash latest firmware

2. Flash the oeminfo and custom.bin

(Both are included in the toolkit. Also, the toolkit will create an backup of the existing files.)

3. Flash the latest build again to align the oeminfo and get the dual-sim working

About the revert, in general yes. But, u can't flash the old file again because there are no provider rom available... So u need to flash the C432 single-sim oeminfo and then the latest C432 build over it.

Regards,

Sebastian
[Huawei P9 Lite ROMs, Kernels, Recoveries, & Other ] buddimanv:
Thanks again Sebastian, done below

1. Flash SINGLE SIM L31C432B151

2. Flash the oeminfo and custom.bin using the tool Dual-SIM>'Upgrade' tab.

Getting unpacking dual sim files failed, any idea?
[Huawei P9 Lite ROMs, Kernels, Recoveries, & Other ] k1ll3r8e:
Heyho,

yup the steps are right ;)

-

About the restore, it might work. But, TWRP don't backup for example the modem partition and some others which gets modified during an update. So the restore

can

work. (U'll lose in any case the original recovery, because u can't get an backup of it without root and without TWRP u can't get root.)

So if u want restore single-sim, why ever, the best would be to flash the single-sim C432 oeminfo and then the latest C432 stock rom over it. So u end in an "Unbranded" C432 single-sim.

Try to delete the "tmp" folder in the toolkit directory and start the toolkit with admin rights. ;)

Regards,

Sebastian
[Huawei P9 Lite ROMs, Kernels, Recoveries, & Other ] buddimanv:
Its not unpacking (Windows 10 64Bit - got admin rights, deleted tmp folder),

Used the 'Individual' tab and use files from L31_DS_C432_by_k1ll3r8e.zip - seems to be working, need to test although my phone is locked to EE and only have one EE SIM card.

Thanks for your help.
[Huawei P9 Lite ROMs, Kernels, Recoveries, & Other ] k1ll3r8e:
Heyho,

that with the unpacking is really strange... Just tested it on my 2cd PC and my VM-Ware (both Win 10 x64), i got no issues...

But seems, u got it already ;) - About the "net lock" there i can't help u. Because so far i know u need a special "unlock" code for this from ur provider. - If i find a solution how we can unlock the "net" i'll add it here in the thread.

Edit:

U could try this service (https://sim-unlock.net/sim-lock/72/Unlock_by_code_for_Huawei_phones/) it cost about 8 € for the sim-unlock-code.

(If u read the comments, seems that it worked for all which ordered an code.)

Regards,

Sebastian
[Huawei P9 Lite ROMs, Kernels, Recoveries, & Other ] buddimanv:
Cheers Sebastian, not sure why it was not unpacking. It created the tmp folder but there was no files....Anyway, the invidual tab worked fine (created backup files as well). Also, when I restored the stock recovery from your tool, it worked (can see a recovery file under tmp folder)....so not sure..

No, not expecting any solution to network unlock :) Waiting for my unlock code (EE say its free now, time will tell - http://ee.co.uk/help/getting-started/joining-ee/unlocking-your-device)

Noticed both SIMs are locked. I was hoping the 2nd one would be unlocked. Also, it seems 2nd sim only supports 2G.
[Huawei P9 Lite ROMs, Kernels, Recoveries, & Other ] k1ll3r8e:
Heyho,

about the code, that sounds good ;) - So, good luck for this ;)

about the 2G, when u place the "main/mobile data" card in slot 2 u'll normally asked by the phone if u want also define this as "default mobile data card" then the 3G will be activated. The device can't handle 2 sims at the same time, this means:

Both cards are active and logged in. When u now get or start a call the other card goes offline until u end the call. Then the other card goes back to standby. So the dual-sim in the complete series of L31 is only a dual-"switch"-sim. But this is the behavior on the most dual-sim phones. They can hold 2 cards online but u can only use 1 active at a time.

Hope this make some things clear ;)

Sebastian

[Huawei P9 Lite ROMs, Kernels, Recoveries, & Other ] buddimanv:
Sebastian, you got me thinking now…

I have a spare Doogee DG310 and also my wife’s Honor 5c (she will get P9 Lite once unlocked), both has two unique IMEI numbers. All these phones are also dual stand-by. However, after converting P9 Lite to dual sim, noticed it has two IMEI but both are identical. That’s bit odd, do you have different IEMI numbers?
[Huawei P9 Lite ROMs, Kernels, Recoveries, & Other ] k1ll3r8e:
Heyho,

when u convert a single-sim to dual-sim the 2cd modem will have the same IMEI as the 1st. That's because there are no 2cd unique IMEI. U can have a look at "/mnvm2:0/SC/Pers/*.*" there are the files and hashes for the IMEI's stored.

But when u convert an dual-sim Cxxx to C432 with the delivered files, it will normally have also the different IMEI's it had before. Because the mount for the data "/mnvm2:0/SC/Pers/*.*" is not touched by the toolkit or the updates so far i know.

Regards,

Sebastian
[Huawei P9 Lite ROMs, Kernels, Recoveries, & Other ] buddimanv:
Yes, I guess that's the limit of converting Single SIM model to Dual SIM - one IMEI rather than usual 2 different IMEI's. Need to test further as I havent used two SIM yet. Interesting read below - :

https://www.reddit.com/r/Huawei/comments/4qh065/p9_lite_dual_sim_feature_uk/
[Huawei P9 Lite ROMs, Kernels, Recoveries, & Other ] k1ll3r8e:
Heyho,

yes it's really interesting ;) - But, so far i can see we don't do anything which acts again this law. Because u are the owner of the device (1st IMEI) and just use it with the 2cd modem. So this might be a grey zone in the UK and Ireland. But we don't re-/program a IMEI number. The both numbers are available from the 1st device start so Huawei wrote this IMEI's inside the files/mount. Also, i'm not really sure about this but, when u look how an IMEI is constructed u'll see, u must create a different device at some point. But this also don't means that this device must be technical different. (See the software block on the 2cd sim-slot)

An IMEI is constructed like this scheme:

TAC = 6 Digits - Type Allocation Code
FAC = 2 Digits - Factory Assembly Code
SN = 6 Digits - Serial-number
SV = 2 Digits - Software Version
CS = 1 Digit - Checksum
TAC FAC SN SV CS
123456 12 123456 7 (IMEI)
123456 12 123456 01 7 (IMEI-SV)

As u can see, the serial can only be 6 digits long so 999999 more devices from 1 type are not possible. Then u have to change the TAC or the FAC, because the CS is calculated by the following scheme:

1 * 1 = 1
2 * 2 = 4
3 * 1 = 3
4 * 2 = 8
5 * 1 = 5
6 * 2 = 12
1 * 1 = 1
2 * 2 = 4
1 * 1 = 1
2 * 2 = 4
3 * 1 = 3
4 * 2 = 8
5 * 1 = 5
6 * 2 = 12

1 + 4 + 3 + 8 + 5 + 1 + 2 + 1 + 4 + 1 + 4 + 3 + 8 + 5 + 1 + 2 = 53
53 mod 10 = 3
10 - 3 = 7

TAC FAC SN SV CS
123456 12 123456 [B][U]7[/U][/B] (IMEI)
123456 12 123456 01 [B][U]7[/U][/B] (IMEI-SV)

PS: I added my IMEI-Validator as attachment.

Edit:

About the SV, the SV is not recognized by the IMEI calculation. It's only the software version which calculated the IMEI it self. (I think this means the IMEI compiler/calculator version on the manufacturer side.)

Regards,

Sebastian
[Huawei P9 Lite ROMs, Kernels, Recoveries, & Other ] buddimanv:
Thanks Sebastian, you really know your stuff :)

Yes, I agree we are not changing IMEI which I think is illegal. Just noticed it, that’s all. From what I read I think in China they release dual sim phones with one IMEI and in other markets like Europe with two IMEI.

Will test once my phone is unlocked to see if there are any issue.
