Hello, I am trying to install the android 5 version but its stuck at 5% of installation for more then an hour. Is that a brick or should I wait longer?
[P8lite General] Azriel_7589:
When you see that it takes more than 30 minutes, you must restart the cell phone by softbrick.
[P8lite General] xPanosGR:
Ok so I got it to work. Had to install android 6 over android 6! and then I went back to android 5. Even tho this is an old thread, everything seems to be working just fine!!
[P8lite General] xPanosGR:
I really need help here. I managed to reach the custom rom installation stage and here is where everything went wrong.

I choose to install lineage 15.1 from here: https://xdaforums.com/t/rom-8-1-stable-lineageos-15-1-for-p8-lite.3928723/

But when I tried to install it I got the following error: View attachment 6011609

I forgot to mention that I wiped everything out except from sdcard which I need for the installation.

What can I do now? Is there a way to fix this issue?
[P8lite General] Azriel_7589:
The tricky part with this device is finding a good custom rom and keeping the links alive.

Anyway, in the twrp configuration part, I think there was an option that fixed the contexts.

In my case I did not install any custom rom from the XDA forums, they were all old there are some that you can find by searching using the model name by google.
[P8lite General] xPanosGR:
Please can you give me a good rom with android 8.1+
[P8lite General] Pier-Dub:
Hello,

I succeeded in installing this version 14.1 (I had the same error with version 15.1):

Which one of these is android 8.0+? So I don't have to spend so much time to find out myself.
[P8lite General] Azriel_7589:
The first two in the list, in the third place I don't know, and the last in the list is android 7 which I use.
[P8lite General] xPanosGR:
Thank you! Have you tried them out? Do they work?
[P8lite General] tralph3:
Wow, I'm so sorry you had so many issues, but thanks for providing your workarounds. The guide follows my experience for the most part, which was much more straight forward.

I would still be using the P8 lite, but one day I woke up and the power button just decided to not work anymore. I got around it for a bit by making the phone wake up with the volume keys, and then getting an app I could put on the home screen to lock the phone.

Then a couple of weeks later it just refused to turn on, at all. It just decided to die out of the blue.

I am on a Xiaomi Redmi Note 10S right now. Great device, and has official support for Lineage, so I won't have to deal with all these pesky bugs unofficial ports usually have.

Hi, does anybody have idea what can i do in this case.

So, i have ALE-L21 with firmware ALE-L21C900B500 and i've tried downgrading with the full firmware but i get error at 5% of update.

EDIT: after 4 hours of trying i gave up and used PotatoNV
[P8lite General] tralph3:
Sorry, you guys seem to be out of luck. Try to look for stock roms for your specific models. It's weird these don't work as they are roms for ALE-L21, so they should be just fine. I mean, they worked on mine which is L23.
[P8lite General] razorfancy:
Apparently [MENTION=7261711]_MartyMan_[/MENTION](*1) was on the exact same build as us and was able to downgrade to version L21C02B893 and then to version L21C02B589, the problem is that I cant find a working free download link of the version L21C02B893, the only one I found is dead(*2).

okay so got tired of searching and paid for the L21C02B893 and that worked successfully and then i was able to to downgrade to L21C02B598. But now im not sure what to do, can you help me?
[P8lite General] tralph3:
Well... Then try flashing android 5 from there and continue with the guide. If it works, send me the file so I can download it and add it to the guide.

Hi, please tell us, if downgrade to android 5 works, or not. Thank you.

I have 2x P8 lite, one ok, one with cracked screen,

first is running on B693

second is running B585

but downgrade fails on both. I am going to try kingoroot on B585 ( sadly, the cracked one). Wish me luck

EDIT: B585 - ROOT failed on 40%. Tried 2x
[P8lite General] Wazu786:
okay so i tried flashing both the transition and the other android 5 but neither worked and i also tried your android 6 and that has failed as well....so im stuck again...not sure what to do now

Can you please upload the Build L21C02B893 to google drive or Mega.nz and give me the link to download? also give me the link of the version L21C02B589 that worked for you.

In that post of [MENTION=7261711]_MartyMan_[/MENTION] that I show you yesterday(*1) he said that he was able to temporarily root the phone using Kingroot PC version while he was on build L21C02B598.

If that doesnt work you probably need to try to downgrade to build ALE-L21C02B181 but the problem is that you have to pay to download it:

https://easy-firmware.com/home/browse/file/id/78828/ALE-L21C02B181/
[P8lite General] Wazu786:
okay i can give you L21C02B893 tomorrow because i don't have wifi right now and ill be going campus tomorrow

L21C02B589 LINK: http://huawei-firmware.com/rom/huawei-p8-lite/ale-l21/2539

damn i can't pay that much for L21C02B181 , it requires you to pay a whole package instead of the single file.

IF i temporarily get the root like he said, how do i get the bootloader code?

Hello, is possible to use C02 FW on phone with C432 installed ? Thanks
[P8lite General] tralph3:
Thanks for the info. Can you give me a link to the one that did work for you? Also, if I understood correctly, you flashed the older Android 6 firmware, tried rootibg with kingoroot and got stuck at 33%, but that still gave you access to the su command on the shell? Seems weird but if it worked I'll add it.

Could someone help me please?

Thanks, I will try this one. I tried maybe 10 firmwares on my P8 Lite but all with no success.

EDIT2 : I do not have time for downloading firmware one by one. I paid 4€ for DC unlocker, got unlock code and unlocked bootloader.

Sorry guys. I think ,there is no other chance to unlock ALE-L21 running FW C432B633.

I rooted and unlocked the bootloader correctly but i just can't update to android 6 or 5 with the recovery mode,when i do it with the usb cable connected it gets stuck at 90% but if i do it without the usb it gets to 5% an instantly says system install failed.

I'm running ALE-L23 Build C40B160a
[P8lite General] Ax1qwer:
Hi, you can update via bootloader and fastboot mode. For example you can use this B896 ROM. https://mega.nz/#!9Q1UHAiR!TVTkIBvatiDoyWf1zOT-0DX4ycRbaXW-1AnndXO3md0 Factory reset after flash is recommended. I lost my IMEI after flashing this and factory reset fixed this issue.

How to do it with a ALE-L23

Well i tryed to install but i had a problem these zips are for ALE-L21 and if you try to install it will get a stuck in 5% or 90%

I tryed only with android 5.0.1 of my ale-l23 installing the B896 update and worked now im testing LOS 14.1 wiouth problems (exept a hardware problem with the wifi)

I suggest an untoched android 5.0.1 wiouth any updates (Because my operator didnt release update to 6.0.1) idk if work in a ale-l23 with android 6.0.1 downgraded to android 5.0

Follow the android 5.0 steps

root the device with kingroot

Do the steps to obtain the bootloader unlock code

Reboot to the bootloader

Unlock it with the code that you obtained previusly

Flash TWRP and do a full wipe

Copy to the SD the EMUI 4.1 update and flash it (j suggest the B896)

Whait if the phone starts and check i u had signal (I didnt had imei problems signal is working normally)

Congrats u had the EMUI 4.1 and u are ready to flash any rom

Afther the instalation if you want to install a custom rom FLASH AGAIN TWRP because the recovery will be replaced with a stock one

Good lock and tanks for the help i wanted to unlock my ale-l23 bootloader`s and finally sorry for my bad english
[P8lite General] tralph3:
I know that the zips I provided are for L21, but my phone is L23 and it worked like a charm, so with some luck they are interchangeable.
[P8lite General] MauriJ2001:
problably can be a problem with my stock rom because is not an international one (i had the stock rom from movistar argentina) but i will test it with a non operator phone now skipping the update to 6.0.1 and flash the B986 directly from 5.0.1 will work for any with the 5 or 90% stuck problem but idk if this process will had some problems with the imei because the update writes (update) in the radio and maybe it`s the problem with the lost imei
[P8lite General] ykruh:
Hi zacchi4k, thank you for that information, in my case I have an ALE-L21C40B that is, branded by Movistar/Spain. The original FW is B515. Based on your information I searched for all L21C40B ROM's I could find, I tried them all to downgrade:

Android 5 transition (from this guide): FAIL

Android 5 Full (from this guide): FAIL

L21C40B514 fullOTA: SUCCESS, phone downgraded, still Android 6 and no rooting possible.

L21C40B508 fullOTA: FAIL

L21C40B185 small file: FAIL

L21C40B181 small file: FAIL

Not sure why I could downgrade to 514 but can not get any other stock ROM flashed, it always fails at the 5% mark...

It seems that the Movistar ROM is avoiding to flash any ROM I try and I can not really find a huge list of ROM's for C40B branded phones.

Any other suggestions ?

Cheers !
[P8lite General] ykruh:
Well I can find a lot of ALE-L23C40B ROM's but my phone is L21 , can I flash those as a temporary solution to downgrade and unlock the bootloader ?

Thanks.
[P8lite General] tralph3:
Pretty sure it's that, as I am from Argentina too but I bought my phone to some chinese dude in a gallery, and it's unlocked, so it's not attached to any carrier. Try to see if you can unlock it somehow.
[P8lite General] CDMCCDMC:
software install fails...
[P8lite General] tralph3:
Sorry, what firmware does your phone currently have? Also, is your phone unlocked? As in, is it attached to a specific carrier or you can use wichever your want? I think that in order to make this work the phone must be unlocked (or "freed").
[P8lite General] ykruh:
Today I tried all the L23C40 ROM's I could find and all fail to flash at the 5% mark, I think I'm out of options.
[P8lite General] ivorocha18:
Hi guys,

I would like to unlock my bootloader but i have one problem: My phone does not boot up

When i go to recovery mode it states "PHONE LOCKED"

Do you have any suggestion? :)
[P8lite General] tralph3:
What do you mean it doesn't boot up? Does it stay stuck at the huawei logo? If so that's a brick, there's an unbricking section in this guide.
[P8lite General] ivorocha18:
sorry If i did not explain it well.

It boots straight to rescue mode

Thanks!
[P8lite General] tralph3:
Then try to install one of the updates by using an SD card...
[P8lite General] ivorocha18:
I think i cannot do that since i don't have bootloader unlocked, am i right?
[P8lite General] tralph3:
You can do that, the first step to unlocking the bootloader is doing that very same thing. Dude a wrote this whole guide, I won't re explain everything, read it please.
[P8lite General] ivorocha18:
Well, i have another problem.

I can only turn the cellphone on if is connect to a laptop or AC charger. It boots direclty to rescue mode with two errors: Func No: 10 (boot image) and Error No (security verifed failed)

I can also boot in fastboot mode - still i can't flash neither the boot.img, system,img, etc.. I cannot boot into recovery as you suggested

do you have any clue?
[P8lite General] tralph3:
Yes, read the guide. I didn't suggest to boot into recovery, I told you to get a file on an SD card and try to turn on the phone while pressing all three buttons. If you want recovery mode for the wipe, just don't do it. If that still doesn't work then it gets out of the scope of this guide and I frankly don't want to try to help out your very specific problem. Not to be rude, but realize that if I help you other people will want help too. You'll need to do research on your own.
[P8lite General] ivorocha18:
The three button option does not work as well.

It is ok not knowing the answer :) . Thanks anyway

Hello will it work on ALE l02 because everytime I try to downgrade using transition package it fails at 4%

[P8lite General] Clashedfiredroid:
Thank you so much!!! It finally works!!!

I'm still on stock android 5 ROM and by build says balongc50b311

If I install the android 6 stock ROM in this thread and it will make the build number normal again?
[P8lite General] tralph3:
It should, the balong bug occurs when you flash an update that's not for your phone, but worry not. It doesn't affect anything really and it happened to me too, so you should be good.
[P8lite General] Clashedfiredroid:
Flashing TWRP failed with error - failed in sendbuffer - unknown error - command failed.

But I have unlocked the phone successfully and I can still boot to emui
[P8lite General] tralph3:
What emui version are you in? If you can root the device, try to root it and flash twrp with flashify
[P8lite General] Clashedfiredroid:
I'm in emui 4.0.

I will try and see
[P8lite General] tralph3:
I don't think you will be able to root it then, as you need TWRP to root in Android 6. However, you have an unlocked bootloader wich may give you access to other things, try to look for a different method. Also, it's really weird that you couldn't flash TWRP via fastboot, are you sure you are doing it right? Please re-read the guide and ensure you are following the steps. If that still doesn't work, then the error you are getting may be because the carrier of your device (if you bought it from them) may have removed some fastboot commands to keep people away from doing exactly this. It has happened to me with other devices, where even a simple "fastboot devices" won't work because there's simply no commands. If that's you case, then you are basically screwed if you can't flash it with flashify, as that would be the only way.
[P8lite General] Clashedfiredroid:
I rooted emui 4.0 using kingoroot (PC version and had to try rooting twice because first time failed)

and I installed TWRP with flashify.

After that it unrooted itself

Then i flashed the b896

Now I cant root the phone
[P8lite General] tralph3:
No, you can't root without TWRP on that update... I'll admit it's kind of a difficult puzzle you have in hands here. You can't use fastboot to flash, so you need flashify, but for that you need root. I'll make something for you and see if it works. Meanwhile you will need to return to the stock version of Android 6, so EMUI 4.0 (the one you could root with). There, flash TWRP again. I'll make and upload a B896 package that doesn't contain the stock recovery, so when you flash it it shouldn't wipe TWRP. It's gonna take me couple of hours probably (mostly to upload) but It'll be there. You do that while you wait.
[P8lite General] tralph3:
Ok, I'm done, here's the update you should flash with TWRP after rooting on EMUI 4.0 and flashing TWRP with flashify.

Android Filehost

Mediafire
[P8lite General] Clashedfiredroid:
Thank you for the help. I will try it tomorrow
[P8lite General] Clashedfiredroid:
I rooted the phone and flashed TWRP but when I flash the zip

[P8lite General] tralph3:
Ok..., but did it work? When you boot, are you in EMUI 4.1?
[P8lite General] Clashedfiredroid:
No. It didn't install
[P8lite General] tralph3:
Try with this one, I replaced the stock recovery in this package with TWRP. It will wipe TWRP, but it will put TWRP in it's place, so no change should be made. Tell me if it works.
[P8lite General] Clashedfiredroid:
It does not install and fails with the same error as with the one without recovery
[P8lite General] tralph3:
Sorry then, I'm kinda out of ideas :/
[P8lite General] Clashedfiredroid:
I GOT TWRP IN B896 UPDATE!!!.

here's how I did it

After flashing the b896 update DONT REBOOT. in other words STAY IN TWRP.

Then flash the SuperSU zip in the first post. Then reboot after installation completed

It will boot loop a few times then after that it will boot into emui 4.1

Use flashify to flash TWRP

Success! Now you have TWRP installed without fastboot on the b896 update!!
[P8lite General] tralph3:
Nice! I knew there had to be a way! That's awesome news man, now you can flash your custom ROM of choice! Talking to you through Lineage OS right now ;) never looked back.
[P8lite General] Clashedfiredroid:
Thank you for the guide. :D

But... My SIM card is not working. It is not detecting my SIM card

Lte works on the SIM card on my tablet

And if I want to change custom roms must I wipe everything except sdcard and install the ROM?
[P8lite General] tralph3:
Yes, you must wipe everything. If you have problems with your SIM that usually means the B896/5 update was not properly installed. As a rule of thumb, if your SIM is working on the B896/5 update, it should work in your custom ROM provided you do a full wipe with TWRP before flashing the new ROM. You could try to flash B895 if you still have problems.
[P8lite General] Clashedfiredroid:
Thanks for everything man! I'll never look at emui again. I'm running Resurrection Remix OS (android 7.1.2) same version running on my S3 mini.

I was expecting something newer for this phone...

I have managed to downgrade my ALE-L21 to Android 5. However, Kingroot fails to root my phone, simply stating "root failed" at 16%.

Can I get some other one-click root recommendations? Or what to do in general, thank you.
[P8lite General] tralph3:
Try KingoRoot (notice it's different from KingRoot), you can also try Framaroot. If those don't work, look for other 1 click root apps, or search for alternative root methods on Android 5.

Did the Huawei update screen appeared on your phone? Did it said it flashed the update succesfully? If it didn't appear then you didn't press all three buttons correctly.
