HCU Client (paid to) claims it can repair IMEI/IMEI2 for Huawei phones

https://hcu-client.com

Maybe also DC Phoenix

https://www.dc-unlocker.com/DC-Phoenix-flash-repair-tutorial
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] vampirian:
Tested with dc phoenix which is known and it didnt work at least for me. Repair yes but adding a secondary on Eva-L09 is not possible. Maybe switching on dual sim cust would work but i dont want to do it cause of multiple things I'll lose :)
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] kergekecske:
The Zx3 has an "Clone IMEI-2" feature. If HCU (or Dc-unlocker ) has it, I will try, but have not asked them yet (I'm very very busy). Someone should try ... if the answer is yes I will purchase the software and try it. Volunteers? :)
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] zgfg:
I can ask them, maybe tomorrow, but what:

Do they support adding IMEI2 to P9 L09 that was rebranded to L19?

They probably don't know, they can claim for IMEI1 and for IMEI2 but on (original) L19

Hello, I have a question, install c432b503 and the battery drains very fast, to go back to c432b502, should I follow the hwota mode or to go back to the previous version of another method?
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] zgfg:
I think yes, HWOTA should work for
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] polosmoke:
Yes? Even to make a downgrade, I run no risk of killing my Huawei?
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] zgfg:
Yes, it should work because it installs no-Check recovery before DLOADing.

But make sure you perform Hard Reset with wiping Internal memory at the end.

However, differences between b398, b399, b502 and b503 should be only in Security patch date, hence not affecting battery consumption or so - maybe b503 comes with faulty GApps causing WiFi issues and draining battery - in which case would be enough to update all GApps but also Google Play Services

The exact part

https://d3nevzfk7ii3be.cloudfront.net/igi/hPqtDsT1TBTEbROq.huge

As I see two full functional sim holders, the second is for sd too. This motherboard has nfc chip so I think this is an L09.
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] vampirian:
Yes that's a L09. But as I said it will be very difficult to do a dual sim on Eva L09. Now I'm gonna test the other paid program cause I already tested with dc. By the way cloning imei as I experienced before with mediate device won't work because only one imei can be registered on the line. If the imei matches with the other sim then most likely it's going to be disconnected from the operator in the best scenario with no signal for both sims .. . Or conflict with your other sim and ban imei. It is possible to generate another imei with some tools but at least in EU there is a law that forbids it and im a bit scared to try it. Now as far i know there is a range of banned imei from that generator. Anyway because of curiosity I'm gonna try the other tool and report back tomorrow
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] zgfg:
I think you need to rebrand to L19 (to have dual SIM ROM) before trying with IMEI2, per instructions (I successfully folliwed the guide and rebranded to L19 two months ago, however second SIM was not recognized and I did not experiment with adding IMEI2)

https://xdaforums.com/showpost.php?p=75855436&postcount=612
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] vampirian:
Reporting back, the generic 2 sim chip is not recognised from the device. Needs a kernel side mod i assume. Tried with both paid tools and there is no result. HCU too. Switched to L19 and i had no results as well. So yeah I give up :)
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] zgfg:
>>Switched to L19 and i had no results as well.

Did you really use the rebranding method as above, that also switches oeminfo as for L19?

If all that, with HCU does not work to recognize IMEI2 and secund SIM, then there is really no hope so far to turn L09 into the dual SIM phone :(
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
I agree :silly:
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] kergekecske:
I know that this is not the right forum. But theoraticly if I had a lot of old, not used phones, could/should I use them IMEI as second? Cuse its uniqe, real and not banned.
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] zgfg:
Generally yes, although IMEI carries info about a vendor, nobody will care and compare against your real phone model (phone also shares some info with the network)

Just make sure that you don't reuse the same IMEI from two diff phones, with the same SIM card (same operator) same day / same week or so

Once I lost IMEI on the old MTK Kitcat phone and I flashed an IMEI from old Nokia and it worked
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] vampirian:
Yes unfortunately rebranding to L19 and HCU did not work :(
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] zgfg:
Unfortunately...

A month+ ago, when experimenting with rebranding to L19 (without HCU) I already bought dual SIM tray (as from L19, because my original L09 tray was able to hold only SD in the second slot) and an extender

https://xdaforums.com/showpost.php?p=76059640&postcount=681

(Still using that L19 tray in my L09 and moved extender to another hybrid dual SIM phone)

Btw - did you have a tray with two SIMs when trying with HCU?
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] vampirian:
Yeah both dual sim slot and extender as well. I was curious enough when I saw the topic about it to do it :! So I bought both of them :)
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] kergekecske:
Hi folks. Yesterday I changed my wifes p20 lite to dual sim. The second IMEI is 000000000000 (more or less) used HWOTA modif by vovan1982 ( https://xdaforums.com/search.php?searchid=448061439 ). As I checked his works he has solution for every (newer) Huawei model . Our developers should ask why we cannot change our P9 (I dont want delegate the task but I am not enough experienced , a single user only ).
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
If phones comes shipped with Oreo debranding has the risk of a totally brick (phone dead) on zero day.

It must not be, but it can maybe - we don't know exactly.

During last month a lot of Mate 10 phones were dead (no Fastboot, no eRecovery, no LED, no USB connection) after one of the next firmware updates. (Firmwares that includes Face Unlock)

Since some of them did rebrand /debrand - but others had the same issue without doing this (just made unofficial Firmware update..)

Some said, it's because of Debranding, other said its related to bad firmware or installing firmware unofficial.

Everything seems to be "dangerous" on Oreo.

In fact we don't know exactly the reason.

The developer of the Mate 10 HWOTA has also bricked his phone totally. (completely dead)

And he removed the function for rebranding from HWOTA and wrote in the changelog: "Remove rebrand function, it bricks phone with recent new ROMs."

At this state I wouldn't recommend to do this (and if it bricks Mate 10 phone it can also occur to others)

Don't worry about my post - you did it already.

I don't say, your phone will get bricked.

But IMEI with 000 (more or less) looks not good to me.

Only thing I know for sure is that oeminfo includes on Oreo the IMEI and SN and some other info of the phone.

I think as long phones was shipped with earlier Android versions (Nougat, MM) rebrand/debrand is no thing with original HWOTA and changing oeminfo (and optional custom.bin)

But on Oreo it's not possible that way and there's another technique (I don't know anything about right now and it isn't my focus)

I heard also Funky Huawei developed rebranding tools which can convert Single SIM to Dual SIM..

I for myself would buy the phone I need without the need for rebranding :)
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] kergekecske:
That is not funkyhuawei method I guess, they not offer this nor for P20lite nor for P9. I tought that the missing IMEI was the reason of our unsuccesful debrand with the L09-L19 and this guy added a second one somehow (ok ok ok full zero, but works :) ) I dont need dual sim P9 , I was just curious . Thanks again.
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] zgfg:
Does the phone recognize second SIM?

It could not attach to network with IMEI=000... but then you can maybe define proper IMEI by using HCU client
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] kergekecske:
The phone recognizes and the network accepts the second SIM with this dumb IMEI .

That is P20 Lite, I thought you tried with P9 L09->L19

I saw that people were also able to convert P9 Lite single->dual SIM a year+ ago, but it never worked for P9

"Huawei has now started rolling out the update in China in phases and will be available for all P9 users in China by 15th July.

However, the update is not yet available outside China but we expect the update to be available soon in other markets as well.

[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Then you didn't flash the data-file patch that matches your device after installing the Rom before first Boot and a reboot of recovery between.

It's exactly described in Post #1 (after the Rom Download Link)

If you don't read what's necessary and required, then don't wonder if you face problems ;)

What was the previous Firmware or Rom you had installed (Build Number)?

From AOSP it's not possible to change to this Rom without the step of installing original Huawei Firmware between.

If your Firmware was perhaps to old and you didn't Update the Firmware before flashing the Rom can also make trouble.

The internal storage must be original decrypted (like on EMUI) otherwise the Rom updater-script cannot flash /data.
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] Xander1611:
That's the point i couldn't install the stock rom so i tried this how can i install the stock rom the best way? And i had lineage os 14.1
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Okay and which Firmware did you have before LOS 14.1?

This would be very helpful to know and it wouldn't be a problem to flash the Firmware (I can give you Links for a Guide how to do it)

But the Firmware must match your device (Model EVA-L09, EVA-L19, EVA-L29 ?) and your cust (c432, c185, c636 or others... (if you had Vodafone or Telekom or any other Branding its necessary to rebrand to an open cust like c432)

And the Firmware Build Number before LOS is also important to know (because it's in the Background and not dependent on flashing LOS or MagicRainbow)

So we would need to know the Firmware Number b386, b394, b398, b504...?

One of the important things is to write down the Build-Number from settings /About phone before flashing Custom Roms...

The Build Number from Magic Rainbow isn't the real Build Number of your device.

Please give me following informations (from fastboot)

fastboot oem get-bootinfo

fastboot getvar vendorcountry

fastboot oem get-build-number

fastboot oem oeminforead-SYSTEM_VERSION

And when we know the information you can flash the right FullOTA-MF Firmware for your device with this method:

[url]https://xdaforums.com/showpost.php?p=75787156&postcount=3[/URL]

It works with TWRP by flashing only the update script (and FullOTA-MF Firmware / zip files renaming see Guide/ must be together with the Nocheck EMUI Recovery in the HWOTA folder on external SD)

External SD required

[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] zgfg:
Something is wrong, please carefully read instructions

https://xdaforums.com/showpost.php?p=75787156&postcount=3

Per instructions, all three update*.zip files and HWOTAUpdateSCRIPT.zip must be ZIP files - but on your screenshot only two of them have ZIP extensions?!

Either you have unzipped the other two (must not), or you are using like Windows 10 and Windoze hide ZIP extensions.

But then those two files you see them with .zip extensions, they must actually be named .zip.zip (double ZIP extensions or what)

Instead from Windoze (please forget screenshots from Windows, they depend on your Explorer settings on the PC), look how do you see HWOTA folder and its file names and extensions from e.g. MiXPlorer on the phone - all four files must not be unzipped, each must have single .zip extension

TWRP must properly see their names and extensions (TWRP will flash).

You can also make screenshot from TWRP by shortly and simultaneously pressing Vol- and Pow buttons, screenshot will be saved to SD card, to the Pictures/Screenshots folder
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
As [MENTION=7786725]zgfg[/MENTION] said:

There are two possibilities. Windows doesn't show by default the file extensions.

Example: If you have a Word Document with the name "holiday" you will see in Windows Explorer only "holiday" and not "holiday.doc" or "holiday.docx" -

You can only see the file extensions, if you manually enable this in the settings for Windows Explorer:

https://www.howtohaven.com/system/show-file-extensions-in-windows-explorer.shtml

You have on your SD (Screenshot) two zip files with .zip at the end of the name, "update_full_hw.zip" and "update.zip"

- but all the other files not.

So I guess, you haven't enabled showing file extensions.

That means, you have "update.zip.zip" and "update_data_full_public.zip.zip"

This doesn't work!

So you can eighter:

- delete .zip from the two files

or: Enable to show file extension and rename update.zip.zip

to:

update.zip

update_data_full_public.zip.zip

to:

update_data_full_public.zip

Hi Tecalote.

Recently, I have accidently format data after error on updating Magisk. Now, I can't boot to OS. The worse cases I don't have any backup and lost my unlock code. But i still got TWRP.

I have tried to reflash the MRv3 ROM zip, it's succeed. But when i flash the patch zip (mine is L19 C636), it failed. I can boot to system, but no Huawei camera installed.

Any idea of what should i do now?
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] zgfg:
Do you mean Magisk v19.x update?

Unfortunately, it has a bug on Huawei P9 (also Plus and Lite models with stock Nougat, nothing specific for Magic Rainbow), asking for Storage Password for Storageand then claiming that Storage is corrupted, and requesting Factory Reset.

If you just rebooted to TWRP and restored backup of your patched Boot image, you would be able to continue using Magisk v18.1 (with no questions for Storage password, no issues about 'corrupted' Storage)

See e.g.:

https://xdaforums.com/showpost.php?p=79493919&postcount=33309

Unfortunately, now it's too late...

Btw, why don't you consider newer Magic Rainbow v4:

https://xdaforums.com/p9/development/rom-huawei-p9-magicrainbow-v4-t3759292

or rebranding to AL10c00 and upgrading to Oreo b540:

https://xdaforums.com/p9/development/rebrand-update-tool-hwota7-p9-eva-t3820849

PS: You could not just flash Magic Rainbow

You had to install the stock firmware first.

IMO, that's the reason you are missing Camera and so.

In the Magic Rainbow v4 thread, post #3, you have HWOTA method how to flash the stock firmware from TWRP.

There is also a newer version HWOTA7 in the post #2 in the HWOTA7/Oreo thread (you don't need to rebrand to Chinese AL10c00, it can be used generally for flashing stock Nougat firmwares) but its script will be asking you for the Boootloader code

However, if you go with the newest firmwares, then you definitely go with MR v4, not v3
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] DanialMus:
[MENTION=7786725]zgfg[/MENTION]

I think I will go with the HWOTA method. Based on the V4 Post #3, step 5 ask me to Search for the correct FullOTA-MF .

I can't remember my last firmware before flashing V3. Any solution?

EDIT:

My bad. I have found the source for firmware which is https://pro-teammt.ru/online-firmware-database-ru/.

But I can't click on the filelist. No list of firmware popped out like the instruction.
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] zgfg:
Most important that you stay with L19c636 (you wrote it was your model and cust).

At the time of MR v3 it was b394 (see the title)., it should update then by OTA to your latest b399

But maybe you can directly flash b399 by HWOTA

With b399 you will be good for MR v4.

But some of the latest firmwares automatically lock the Bootloader (even on OTA update)

I have finished flashing HWOTAUpdateSCRIPT.zip. The phone reboots to EMUI recovery and finished installing the firmware until 100%. The phone gets to reboot. After Huawei logo appeared, the screen went blank until now.

[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] zgfg:
Some people make mistake with file naming.

Windows 10 hide extensions by default and they rename update*.zip files to have double .zip.zip extension.

If one is wrongly named or not present at the proper path, script fails to flash.

You can try to reflash.

You can try with eRecovery:

- switch off, connect to the charger (!) and boot while keeping to press Vol+

- in eRecovery, select to install the latest firmware and recovery
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] DanialMus:
I forced the phone to reboot to system by holding power button. Finally, the system boot successfully. Thanks mate!

Now, I can flash to V4 right? With the patch zip, since mine is L19C636.
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] zgfg:
For MR v4 you must be (please double,-check) on b398 or newer.

Double-check if you have all apps like camera and so.

If needed you can reinstall by eRecovery and/or Factory reset + Wipe cache (must not have TWRP while Factory Resetting).

I have MR v4, but on L09c432, hence double-check which patches apply to your L19c636

MR v4 comes with Magisk v16.1 or so.

Search for (Magisk) v18 in the MR v4 thread, you will find my posts how to update Magisk to v18 (Direct method will not work).

You will need to find/download Magisk v18.1 and manually update to by TWRP.

Then stay on Magisk v18.1, unless you want to have storage/password issues with v19 again :)
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] DanialMus:
What should I do if Magisk asked to update from 18 to 19? You have said something about restoring patched boot image. But i have no idea what it is.
