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.

Thanks for the mirrors to Robertuzu and Kajartandi

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.
[Huawei P8 Questions & Answers] raoulserban:
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
[Huawei P8 Questions & Answers] haki.gr:
They probably rectified the problem and they are now offering the correct firmware for downloading.
[Huawei P8 Questions & Answers] raoulserban:
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
[Huawei P8 Questions & Answers] raoulserban:
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.
[Huawei P8 Questions & Answers] gianluk:
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.
[Huawei P8 Questions & Answers] raoulserban:
i used the same sims in another p8lite(dual sim from the store). it is not the sims
[Huawei P8 Questions & Answers] raoulserban:
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

http://consumer.huawei.com/es/support/products/index.htm?pro=ALE-L21 the open market firmware
[Huawei P8 Questions & Answers] gianluk:
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.

[Huawei P8 Questions & Answers] rmrbpt:
If you bought your device as single sim then you're not supposed to have two IMEIS even if the device can be used with two sims after the change you made on firmware.

It will work as a Chinese dual sim phone. They work as dual sim even though they only have one IMEIS.

If the two sims are from different networks there shouldn't be any problem.

If you have two sims from the same mobile carrier then I am not sure if it will work.

german Telekom P8 lite to switch to dual sim

Hi guys,

i read through this thread (and seberal others), but still am unsure about levels and numbers to go for a dual sim version on my p8lite.

Actually i have just received the official upgrade so my ALE-L21 is now on EMUI 4.0 and Android 6.0 wiht a Build number of ALE-L21C150B585

I am totally unsure wether this qualifies for any of the downloadable packages mentioned earlier on this thread.

I did the unlock procedure via the 'Minimal ADB and fastboot' tool .... and it worked like a charm ... the little green Android Icon was showing a red "Phone unlocked" right away after

entering my unlock password ... however ... nothing changed on the 'Settings' view ..

i simply dont have any 'Dual - Sim Setting' menu item at all ...

Can someone shed some light, whether my above mentioned version can be updated or .. manipulated to get the dual sim working ?

Many thanks in advance !!!

1. Download ROM:

2. Read the instructions in the archive which you have downloaded. Pay attention!!! You must flash the second file also - that enables dual sim.

I finally managed to unlock the 2nd Slot!!!

First to say: My stock rom is ALE-L21C432B613 Single SIM / Only one IMEI

I had no menu for Dual sim managment and 2nd slot the second slot was inactive (not working).

In previous posts, I saw a user saying that is needed to flash only "UPDATE.APP" from folder "CUSTOM" in "ALE-L21 C432B132 Europe channel Dual.rar"

Link to full ALE-L21 C432B132 Europe channel Dual.rar: http://download-c.huawei.com/download/downloadCenter?downloadId=52903&version=140893&siteCode=hu

Link to "UPDATE.APP" from folder "CUSTOM": https://mega.nz/#!rMJREDQC!WM-qaR2d9kPgFqI_AzsQ4wVCGu148fzvDWgFyNupsfQ

After installing UPDATE.APP the dual sim management menu appeared in my phone but both SIM Slots were inactive. Even if I used only 1 sim card, they were inactive.

Then I found ALE-L21C432B613 (Dual sim) Europen variant.

Link: http://update.hicloud.com:8180/TDS/data/files/p3/s15/G2068/g1647/v103464/f1/full/update.zip

After installing UPDATE.APP from update.zip my phone has finally become a working dual sim variant.

But the phone has only one IMEI so when I use 1st sim for calls, the 2nd sim becomes inactive. This may be due to the fact that I use the same carrier on both sim cards.

I'll try to test with sim cards from two different carriers if I'm lucky, maybe both sim cards can be active at the same time.

Huawei p8 lite no wifi solved

For the wifi problem reinstall step 2.

1. Copy update.zip (do not unzip it) in dload folder on sd card. DO NOT UNZIP!

2. Go to SETTINGS - SYSTEM UPDATE - MENU - LOCAL UPDATE - SD CARD. And install it and it solves the wifi.

Update.zip it has 163 mb approximatly. Don't remember exactly.

It is the same update that you installed and it blocked your wifi. But this is the correct way to install.

Good luck!

Step by step how to :

[

Hi - This is really working : see the detailed step by step below :

I have bought a P8 lite from Vodafone .ro , with dual sim option blocked.

Step 1 - Download ALE-L21V100R001C432B046b.rar from link above .

Step 2 - Unrar - you will have two folders STEP 1 and STEP 2

Step 3 - put both SIM - Micro and Nano in phone sim slots

Step 4 - Connect the phone on computer as USB drive

Step 5 - Copy From folder STEP 1 - dload folder on your root phone internal storage \ !!! only the dload folder

Step 4 - Disconnect the phone from computer

Step 6 - Start update procedure --> settings - update - local update - at this step the Vodafone logo will be replaced by Huawei one and other major changes .

Step 7 - after first reboot use sim pin if is asked (usual 1234)

Step 8 - Connect the phone on computer as USB drive

Step 9 - Copy From folder STEP 2 - dload folder on your root phone internal storage \ !!! only the dload folder

Step 10- Disconnect the phone from computer

Step 11 - Start update procedure --> settings - update - local update - at this step the update procedure is finalised.

Step 12 - after reboot use sim pin if is asked (usual 1234) and both SIM sd be visible .

Just above the WIFI in settings you sd have dual card management menu option.

With these steps on my P8 lite from initial single sim :

- build number ALE-L21C02B130, and custom soft version probably requested by VDF- custc02d001 -

I have after upgrade dual sim working :

- build number ALE-L21V100R001C432B046b and no custom soft version.

You're somewhat right, however you will get the ROM itself too. I managed to download some russian thingy, and got a nice maleware too, had to reinstall my pc in order to get rid of that virus. :/

I'm extraced the CUST.img of this ROM, and found a bunch of XML files in there, one of them named unstall_apk.xml. I found one entry in it, which whas the HWCardManager.apk.

I searched through the SYSTEM.img, and found out, that this file is present in the image, but I cant find it on my phone. It looks like this XML is responsible for deleting this apk file.

I zipped the file, and uploaded it to my Google Drive. Unfortunately I can't post links or attachments, so here's the link in this form. (just remove the spaces)

https : // drive . google . com /open?id=0B303_1pmtlHITzY3M3pFQVdHRUk

You should insert this folder into system/app.

The folders permission should be this: rwx r-x r-x (755).

The files inside the folder: rw- r-- r-- (644).

Please tell me if it works, because I can't try it in lack of another SIM card.
