[SOLVED] Anyone has the stock rom for Huawei P8 lite? Enable dual sim P8lite.

Hello, i need the stock rom for Huawei P8 lite because in my country the carrier sells the phone with the second sim disabled from rom software.
I just need the stock rom to replace it.
Thx in advance.
//Edit:
How to enable dual sim:
1. Download ROM: https://mega.co.nz/#!rcFDzZSa!V1zxHlmSqIvhF1_FjIOsyu762s8ZURmYDRtxcQeDyI0
2. Read the instructions in the archive which you have downloaded. Pay attention!!! You must flash the second file also - that enables dual sim.
3 If u followed the instructions corectly u should have dual sim.
Many thanks to @kjartandi !!!
Official downloads if anyone needs it: consumer.huawei.com/at/mobile-phones/support/downloads/p8lite-at.htm
Here are the official downloads
official downloads: consumer.huawei.com/at/mobile-phones/support/downloads/p8lite-at.htm
@kjartandi does this rom is for dual sim version of the phone? because i need the stock rom which has the dual sim integration. my phone comes from the carrier with single sim rom software
Is your p8lite dual sim? Did you test it with nano and micro sim?
Thx in advance.

theoretically yes beacause all p8lite are dual sim by manufacturer
hello. i followed the same steps and the results are following:
-P8Lite Orange RO, single sim so called variant
-Flashed the ROM via tutorial, Step1 and then Step2.
- ROM has now dual card(sim) management enabled. Upon start it requieres 2 PIN's, each for every sim.
Only SIM1 has signal, sim2 has absolute no signal. When sim1 is disabled from dualcard management only then sim2 has signal. did a reset, started from scratch, same story.
is there any way to resolve this. to make it completely Dual Sim Full Active, as it should be from Huawei. The Huawei P8lite codename is ALE-L21. No other variant.
from huawei site i could not download any ROM.

I've seen the same problem reported here:
htcmania.com/showthread.php?t=1016301&page=7
The user fixed the problem flashing the spanish firmware.
I've downloaded both firmwares (MEGA and Espana). The only difference is in the "step2" folder (it doesn't exists in Spanish firmware). Step1 folder IS THE SAME.
So, in my opinion you shuld try to flash only the "Step1" folder and check if all is ok.
Let us know if this fixes your problem

Afew days ago I bought one from Vodafone in Greece which was branded and thus it supported only one sim card. I just flashed the official B046 firmware and the phone now is dual sim. Of course it is nοt Dual Sim Active as very few and expensive phones are. It's a regular Dual Sim Standby phone which disactivates reception on one while on a call on the other. Don't flash the "Spanish" firmware. I did, a week ago, and I ended up with a phone that thought that it had firmware B311 and that it was a different model. I couldn't even do a hard reset! I then downloaded the Mega firmware, flashed Step 2 first, then Step 1, then Step 2 again and then I did a hard reset. Now the phone works brilliantly.
i have flashed the spanish firmware. same story. only one sim at a time has signal. at one point both did not have signal, kinda paniked. the spanish firmare allowed me a reset and the data about phone and firmware was same B046.
I am trying now to do step2, then step1, then step2 again than a reset. hopefully it will bring something
They probably rectified the problem and they are now offering the correct firmware for downloading.
no succes.
so... i have no other idea.
i have used the Mega download with 2 steps. i have used the spanish firmware. all of them have the same build number.
everything goes smooth while "upgrading" via sdcard.
i do not know what to try. it is interesting that i have signal on sim2 only after i disable sim1. when sim2 has 4g data enabled then both sims do not have any signal
i have downloaded all available firmwares. i even downgraded to b041 from b046b. SIM1 has signal, sim2 has no signal. when one is deactivated , the other one has signal.
i did a hard reset every time after the flash. No success! can anybody with more knowledge on this investigate and help.

Your sims supports 2G? Because when you enable all the 2 SIMS, the second one goes in 2G.
For example, in my case (H3G Italy), I can't use my SIM in 2G, so if I enable the 2-SIM mode, the second sim has no signal.
I must use (as second SIM) another operator which supports 2G mode.
i used the same sims in another p8lite(dual sim from the store). it is not the sims
Dear Admin, please mark issue as Unsolved.
i have tried 5different sims. just to be sure. same issue.
i have flashed again the Firmware from Mega file. step 1(b046b) and step 2. no resolution.
i have downloaded from huawei 3 firmwares. one called open market(b046b), one marketspecific(b046b), one from malaesia(b311). flashed them all, same issue.
Phone works great, yet it is a shame i can not use it as Huawei designed it(aka dual sim full active, signal on both sims simultaneosly)
there are P8Lites , like mine, with vendor specific firmware, where the second sim is disabled. there are users who managed to free the sim2 slot without any issue yet there are users who could not do that. what exactly did the vendors do is unknow for now and we need a dev for a custom rom.
please take a look!
ps: there are users who say that the latest OTA update(b052) brings signal to sim2, but it is not confirmed by many

Only a clarification: P8 Lite IS NOT DUAL SIM FULL ACTIVE, it is Dual Sim Dual Standby: the 2 Sims works concurrently, but when you receive a call on one sim, the other goes offline.

Yureka network problem.

Hey guys, my friend brought to me a Coolpad F2 (don't know where he got it from) with a micromax rom installed which had network problem. On researching I came to know that Yureka is a rebranded version of Coolpad F2. So I flashed yureka official firmware. But still I couldn't solve the network issue. Another weird thing about this phone is that there is only one imei number printed on the phone and the second SIM slot doesn't detect SIM. The phone works perfectly on 2G network, data keeps disconnecting on 3G and no signal at all on 4G(Jio). I've tried everything and every tricks I could find on the internet but no luck. My only thought now is trying a different baseband from another similar phone (I couldn't find modem file of coolpad F2). Any suggestion would be much appreciated.

Airtel Volte [How to Enable It]

Hey guys, I have finally arrived at a proper result after a long time.
Airtel supports Volte in all areas except J&k. , as mentioned on their website: https://www.airtel.in/volte/
Note: First u need to have an Airtel 4g sim along with a 4g/3g data plan.
So the steps to activate Volte is simple :
1. Go to the airtel Volte website given above.
2. Check for compatible devices
Note: You will be needing any one of the compatible devices listed by Airtel on their page.
3. Now you have to put your sim in the device [ compatible one ] and they reset the network settings of the device.
4. Now restart the phone and wait for some time.
5. After doing so you would get a link from Airtel.
Note: Something similar to this - Please open the following link to get manual instructions for service settings.
http://10.89.22.101:9080/SADM/Manualgrp=Auto+Device+Detection&rcId=4&msisdn=%2B91<airtelmobilenumber>&dev=Xiaomi+RedmiNote5Pro
6. After clicking on the link, you have to restart the device.
7. Airtel Volte will be enabled, now you can put it back in your Zuk Z2 and Volte is enabled.
And for those who want to know what rom I am running on,
Rom: Jaguar version January 10
Gapps: Mind the gapps
magisk: Installed
Hit the thanks button if I helped you.:good:

ok to solve your issue, all you gotta do is follow this website: https://forum.xda-developers.com/showthread.php?t=3695877 get the latest version of Indian stock rom guess (zui 2.5) and install that using qfil.
now set it up and enable volte on the device. Then follow the steps given above. Happy Flashing :good:
No matter what I try, wait for similar message as given in #1 or call customer care for volte settings they are just providing me with Instructions on how to enable VoLTE in settings.
I'm not able to get beyond that point i.e., not able to receive the link to enable VoLTE on my sim card.
I didn't got any link but kept my sim in poco f1 for 4hrs it's worked for me....
Now i can able to use volte in Z2 Plus....

Oneplus 8 Pro VOLTE - Android 11

Hello All,
Has anyone been able to get VOLTE to work on OP 8 pro after Android 11 update ?
There was a method through QPC on Android 10. However it looks like since updating the Qualcomm device doesn’t show up anymore.
The option is still present on engineering mode & in settings but the VOLTE icon doesn’t show up & making a call results in network reverting to 3G (H+) .
Funny enough this update (11) got the 5G to work but disabled this option above.
I am on IN2025 North american varient on 1 sim in sim 1 , not rooted either but willing to try anything to get VOLTE to work.
Any insight would be appreciated !
Hello everyone, I am facing exactly the same probelm. Searching other threads including oneplus forums... there is a dead silence regarding this.
Seems folks dont know how to switch the phone to full port mode or serial mode to get qualcom tools to work and upload volte profile on the phone.
Hope this will be known soon. Otherwise really happy with Android 11, second SIM started to work.
Hi, I'm going to give you a feedback on the volte and vowifi with Android 11.
I have two French sim cards.
Under Android 10 I was how everyone had to use the PDC software and load the correct country profile. At each update obliged to redo the manipulation.
Since Android 11 and the first beta developers and open beta. No need to do this manipulation anymore.
I made a data wipe from the recovery, to start again on a healthy basis and Android 11. Of course I did not have the volte etc ..
I just downloaded the engineer mode apk and made the key combination * # 800 #
To activate the volte and the vowifi.
My OnePlus 8 pro is of course not recognized like everyone else by PDC under Android 11.
But when restarting the wifi rt lte calls were available on my two sim cards. Without having loaded any PDC profile.
Perhaps these operator options are native and integrated in Android 11 (at least for French operators).
Currently I am under open beta 2 global.

Hello Zayatoshi,
So you just wiped the phone after 11 update then it just shows as working ?
I am able to use engineer mode apk with *#801# combination the option is showing in settings but VOLTE is still not working making a call it goes to 3G (H+).
I am in Canada on IN2025
Hi. with me the wipe data was not linked to the activation of the volte and other. but with each change of version of Android and prefers to redo a clean installation. the * # 801 # key combination is useless because it is used to switch to full port Switch and then connect to PDC. friends seen under Android 11 the op8pro is not recognized it is useless. the wipe may be tested. but did you activate the volte and vowifi with * # 800 #, and restart your phone? These options must be active with the operators. And with Oos there is the volte logo which is present when this option is activated. I just activated these options and since the volte is present even after each update. without pdc uses
Envoyé de mon IN2023 en utilisant Tapatalk
Yes i activated with * # 800 # & restarted the phone ,there is no Volte icon & when i make a call Its going to 3G.
Ok guys by some miracle I got it to work!!!!
Here's what I did.
Install stable Android 11 full version.
Use *#800# to activate VOLTE then restart.
I then switch my sim card from OnePlus 8 Pro to my old galaxy S9 where VOLTE was working before then make 1 call to ensure volte is working on S9.
Then switch sim back to OnePlus 8 Pro & boom VOLTE is working on Android 11 !! .
VOLTE Is working for me on 4G after the update to 11 ,Is 5G working after the update?Mine is not working,It used to work on Android 10 but not VOLTE !
weird
both VOLTE/Wificalling works
Yes can confirm 5G is working after updating to Android 11 ??

I have followed this method and it did not change anything for me.
Provider - Freedom.
I have another phone Pixel 3a, pulled SIM from OP , put it to Pixel, ensured volte / wifi calling works there , switched SIM back to OP , no result.
Looking for another solution. I don't believe reset of the phone will make any difference.
Thanks all.

Did you make a call on Volte on the other phone ?
Make sure it stays on LTE for that call to confirm its working (on other phone) then put the sim in the OnePlus.
Also, did you enable volte on OnePlus using engineering mode ?
When I enter *#800#, all I get are call log kits. I'm sure sure how or where I can turn on volte.
Same here

VOLTE Issue with One Plus 8 Pro 11.0.1.1.IN11AA Update

Hello. I am using OP8P IN2020 with Global Firmware. While i am using volte without any problem with version 11.IN11AA, after updating to 11.0.1.1.IN11AA via ota, realised that volte stopped working. The volte icon disappeared. Checked settings and Volte option is still active but it doesnt work.
Tried switching to EU firmware "11.0.1.1.IN11BA" that didnt work too.
Downgraded to 11.IN11AA Stable Global version and it seems it worked. So i OTA Update to 11.0.1.1.IN11AA again and volte stopped working again.
So here is the result for me with 11.IN11AA VOLTE works. With 11.0.1.1.IN11AA and 11.0.1.1.IN11BA VOLTE does not work.
What is it about? Can i somehow fix this?
Root is required to have accsess to PDC and through it you can change the volte profile with no root your device won't be detected by PDC and nothing you can do to activate volte
So is there a guide to how to use pdc and activate volte for our device?

Yesss. With your guide i made it. Thank you very much.
Oxygen Updater
I upgraded to 11.0.11.IN11AA early this morning utilizng Oxygen Updater and my VOLTE shows it's icon up the the far right corner. Seems it's working fine. I'm sure y'all have a way to verify if it's truly working, so please have patience with me as this is all new to me. I'm a NUG (new useless guy) as we called new engineers in the Datapoint world, almost 40 years ago. You've probably never heard of that company.
Thanks for this post and thanks to all you people I'm learning so much...
