If you did a backup with twrp you should have your old oeminfo and can go back to L09, If you got test-keys that means you had a branded phone and i would only recommend using the l29.

Other way is to load a l09-rom: http://pro-teammt.ru/firmware-database/?firmware_model=vtr-l09c432&firmware_page=0

Simply replace the 3 files in the hwota folder with the new ones and be sure you rename them to orginalname, otherwise the script won´t find the files.

Thenuse the script and rebrand to l09.

But you have no advantage of using the l09. Huawei versions differ from device to device. If you have and B164 on the l29 right now, it doesn´t automatically mean that for instance a B175 on the l09 is newer. You mostly have to look on the release date to compare.

Dear friend! If you write to press vol- and connect the usb cable then i do. Do not think I am out of mind. I did it in many ways and none succeeded. Maybe I'm not omnibus but basic knowledge I have. Sometimes the device is faulty. Now I sent a phone call to the service and wait for answer.

Unlock bootloader was OK, but maybe I had too little energy in my phone when I tried to relock bootloader.[/QUOTE]

I can only rely on what your writing back.
[Huawei P10 Guides, News, & Discussion] AlkyXDA:
No, I do not have a branded phone. It is/was an unlocked EU version, not owned by a carrier.

Yes, I have the L09 oeminfo still. I flash that via HWOTA to 'rebrand' the phone back to L09, together with the 3 files of a L09 rom.

The result: The Simcard is never recognised.

I don't care so much about advantages of the roms at this current moment, I care more about being able to succesfully revert the phone back to it's original state ;)

If I read your reply correctly, you advised flashing the 3 rom files via HWOTA first, THEN flashing the L09 oeminfo? Hmm.. haven't tried that yet.
[Huawei P10 Guides, News, & Discussion] AlkyXDA:
Still no luck yet getting the Simcard recognised. Though, funny thing, I'm probably the only one on the planet that has a dual-sim L09 :silly:

Iam i missing anything?

**** i think i got it i completely missed the need of the firmware finder, but i doesn't allow me to install by proxy,can i include the folders in the Hwota folder and do it that way?
[Huawei P10 Guides, News, & Discussion] AlkyXDA:
Thank you for the link. He sure has something fishy going on.

Mine didn't have the 2nd simcard slot available in the About Phone when it came out of the box. That only appeared after having flashed a L29 rom on it and rebranding it back to a L09.

I am at the point where I can deduct my backed up oeminfo to be at fault, as I have also flashed other L09 oeminfo's too with the same outcome: dual Sim activated but the simcard is not recognized in either slot.

Sadly, there's no instructions around how to revert back to L09 properly, so maybe I am missing a step somewhere??

Depending on certain factors rebranding to L09C432 may not work. However rebranding to L29C636 has worked on all devices so far. If L09 fails to read the sim, try L29, even if your device is L09!

do you simcard contain pin code?

Hi, I received my P10 from service (replacement of the motherboard). I had branded firmware but now they install me open europe soft (vtr-l29c432b151). I find on the internet that the newest soft is b164. I search for updates in the phone but I can see the info that I have recent software. What can I do to update to the new soft?
[Huawei P10 Guides, News, & Discussion] M1chiel:
Be patient or install the Firmware Finder to force the update. B171 is also available for C432.

Hi all

I rebranded my phone Huawei P10 L09C432 (Single SIM) to L29C432 (Dual SIM) by manual on this forum,.

After this rebrand all works ok and all SIM works ok with no problem. Now i want sell my phone and he has warranty. I want back to L09. I do the same as rebrand to L29 but use in script oeminfo L09C432 and write firmware for L09. But after this phone works ok but SIM card in slot 1 not working. No found and no signal and no ask for PIN,

When again come back to rebrand to L29 SIMs works ok.

Before rebrand i dont save my file oeminfo.bin by recovery. Is possible to write oeminfo from other phone P10 L09C432 ?

Please help me...
[Huawei P10 Guides, News, & Discussion] pepe_lodz:
Hi

Did you resolve your problem ? I have the same...

I dont understand this.

When now i have rebranded P10 from L09C432 to L29C432 now i must rebrand by script to L09C432 but in directory update HWOTA i must have firmware for L29 ?
[Huawei P10 Guides, News, & Discussion] AlkyXDA:
It has been a while since i last flashed an original rom onto my P10. I am using Blackball's P10 rom, which is pretty original.

For safety's sake, whenever i wanted to flash a L09 rom, i always made sure i had a L09 version in the HWOTA update directory. If i wanted to flash a L29 rom, i put a L29 version in that directory.

There is some discussion if the L09 and L29 rom files are actually the same, just with some added files for the L09 or L29, depending which version you want to flash. But, better to be safe and put the according rom files in the HWOTA directory.

---------- Post added at 07:35 PM ---------- Previous post was at 07:26 PM ----------

As far as this question is concerned, i just answered your pm. :)

Supposedly, the Simcard recognition problem after rebranding back to L09 is due to the Simlock pincode being enabled. (I haven't tested it myself yet, but i plan to as soon as i have some free time)

So, best thing would be to disable the Simlock pincode while you are still running the L29 rom, then rebrand to L09 and install a L09 rom.

If you have already rebranded back to L09 and flashed a L09 rom, try disabling the Simcard pincode and then restarting the phone.
[Huawei P10 Guides, News, & Discussion] pepe_lodz:
ok thanks.

But i dont unserstand this:

If L09 fails to read the sim, try L29, even if your device is L09!
[Huawei P10 Guides, News, & Discussion] AlkyXDA:
They are saying, if you get Simcard problems after you reband and flash a L09 rom to your phone, try a rebrand to L29 and flash to L29.

This does NOT mean rebrand and flash to L29 if you want a working L09 rom.
[Huawei P10 Guides, News, & Discussion] glehel:
Yes, all 3 update file put the update directory.
[Huawei P10 Guides, News, & Discussion] pepe_lodz:
But when i try rebrand from L29 to L09 also should put in update directory 3 files zip with firmware for L29 not for L09 ?

---------- Post added at 10:51 PM ---------- Previous post was at 10:11 PM ----------

Ok after rebrand to L09 i test it with disable PIN for SIM CARD. When PIN is disable , SIM CARD is reconized and works ok. But when i enable PIN again and restart phone again SIM CARD is not reconized. No signal...

But also still in menu Settings is show option DUAL SIM SETTINGS.

I dont know where is a problem.
[Huawei P10 Guides, News, & Discussion] pepe_lodz:

Next update my problem.

I write by SDCard service software version L09C432B171. All update ok but still is available DUAL SIM SETTING in menu and also still not working SIM Cards with PIN. When disable PIN on SIM all works ok, And after that found custom update from my network TMOBILE name number: A26002F01D012POLC150F01D012

I installed this update. After that enable PIN on SIM and card works ok. Is reconized. I restarted my phone and SIM CARD always reconized and works ok.

But in menu still is DUAL SIM SETTINGS and when i done FACTORY SETTINGS , it removed TMobile uopdate A26002F01D012POLC150F01D012 and SIM CARD again is not reconized with enable PIN.

I dont know how resolved problem.
[Huawei P10 Guides, News, & Discussion] LwannaCM:
That´s why backups (especially OEMinfo) comes always first. If you have a TWRP backup before the brand, restore it.
[Huawei P10 Guides, News, & Discussion] pepe_lodz:
But i dont have backup Oeminfo. I am not create before rebranding to L29.

Can i use oeminfo from other L09C432?
[Huawei P10 Guides, News, & Discussion] LwannaCM:
That´s your bad, there are plenty of warnings in the tutorial ;) If you had a L09C432, it should be possible. Your sim failure on the other hand says otherwise.

Seems you had branded one, then you can only revert back to this one, but i know for fact, that providers sometimes change something depending on the builddate of the device in the oeminfo, even if it´s the same model.

So you only have a choice, if someone has a backup from the same series.

If you are really sure you had a L09C432, then try to replace the update_all_hw.zip in the folder hwota\update (Important: You have to use the new one - B180 !!) with this one: update_full_VTR-L09_hw_eu.zip and rename it again to to update_all_hw.zip. Be sure you set your option in the os, that shows you the suffix. Otherwise you might end up with a update_all_hw.zip.zip ;)

Run the script again.
[Huawei P10 Guides, News, & Discussion] DiMeteo24:
is this update VTR-L29C432B180,VTR-L09C432B180 will be OK for VTR-L29C432?

What you mean write about sufix ?

But also oeminfo is available in files script:HWOTA\oeminfo\VTR\VTR-L09C432.bin

It is other than my original ?

I must only one file replace and rename ? Update.zip not replace ? And what use in script ? Rebranding to L09C432 ?
[Huawei P10 Guides, News, & Discussion] LwannaCM:
in the file "update.zip" --> .zip is the suffix

That´s an oeminfo for the original unbranded phone used durcing the unbranding. Could be yours. could be not. Read what wrote in the post before.
[Huawei P10 Guides, News, & Discussion] pepe_lodz:
Ok summary

1. I download from this thread new script for rebranding B180 from this link:https://mega.nz/#!AKRHTJoB!NT5zRsqOYFgH8d4Wd93rTLIrnDZA6Y4Z2OWTyoXgowM

2. extract and then replace in hwota\update file update_all_hw.zip with this file : http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1901/g1604/v105736/f1/full/VTR-L09_hw_eu/update_full_VTR-L09_hw_eu.zip

3. Unlock bootloader and run the script and what i must select ? Rebrand to L09C432 ? (but in HWOTA is correct update.zip for L09C432 and not for L29C432 ?)

I dont understand... if in script is oeminfo for original unbranded phone why when i use rebrand to L09C432 Sim not working but when use rebrand for L29C432 sim works OK. My phone is from Polish T-Mobile original i dont see any branding.

Ok i done as i write in summary and still in menu is DUAL SIM SETTING and not see SIM CARD with PIN. Nothing change still the same problem.

I still dont understand why on OEMinfo from L29C432 (rebranding) SIM CARD with PIN works ok but on OEMinfo also rebranding SIM CARD not working with PIN.
[Huawei P10 Guides, News, & Discussion] AlkyXDA:
As I cannot judge on the situation from [MENTION=543413]pepe_lodz[/MENTION], as he has his phone from Tmobile, I have repeatedly reported the same issue with my unbranded L09.

I did not purchase it from a provider, but from a european Huawei phone reseller, which came with a L09C432 rom.

But yes, also I did not do a backup of the original oeminfo. My own mistake of course.

The issue persists no matter which L09C432 oeminfo is tried, and believe me, I have tried nearly every one of them available on the internet.

Tried it as well, but to no avail. Rebranding back from L29 to L09, even with the update you supplied, does not fix the current issues:

1. Simcard recognition failure

- workaround is to remove the Simlock code, though for people who want complete security this is a crappy option as the Simlock code cannot be reenabled again unless you want recognition problems.

2. "Settings" still shows "Dual Sim Management" options after reverting back to L09, even with original oeminfo.

- no workaround

It would be great if someone with the technical knowledge was able to make a project out of this and at least find the direct cause, if not a permanent solution :)

Someone who is willing to do a rebrand back to L09 using only a oeminfo file and the B180 rom (or even a previous rom), and NOT using their own full backup ;)
