Can you provide instruction on how to disassemble the phone. Also where to order spares from. The digitiser on my Storm is cracked and Wileyfox want to charge me the price of a new phone to replace it.

Eh, sorry mate, I don't know how to disassemble the device and no one else sure as hell knows how to do it (at least on other websites). There are only reviews and unboxing experiences of the Wileyfox Storm and guides on how to flash ROMs, root and recoveries, etc. But some member will help you out, surely! If nobody seems to be knowing the issue, pm a forum moderator so that he/she can guide you to some links/methods. :fingers-crossed: Best of Luck!

Downgrade to android 6.0 marshmallow
Hello everyone, well recently my phone updated to android 7.1.1 and I didn´t like very much, so could help me and tell me if is there a way to go back to android marshmallow 6.0, just like it came when I bought it. Is it possible and does anyone know how to do it?

Okay so im trying to get lineage Os on my phone, this OS isn't working at all i get in bootloops etc. So i tried AOSP extended and i managed to get this working. But when i try to install gapps or try to flash Super su or magisk it returns error 1. The problem is in the recovery probably. So i tried to flash / boot a different TWRP version but all of the other versions give me this error: FAILED (remote: dtb not found). I would appreciate any help i can get i am hardstuck because i cant get a proper working TWRP recovery working and the only rom i am able to flash is AOX but without gapps that isnt worth much.
Thanks in advance.

First of all, what build of LineageOS are you trying to install??? If it is dated 12.07.2017 or 05.07.2017 - it won't work at all. That builds are broken. Use 28.06 or 21.06 build.
Secondly, what TWRP version do you use? I installed LOS via TWRP 3.1.0.0.
Newer version is available now.
And what bootloader version do you have on your Storm. I mean what stock ROM was installed before installing TWRP.

It seems to me, AEX is pre-rooted and comes with magisk pre-installed. When I installed that - only gapps were necessary.
Gapps need to be installed immediately after installing ROM, without any reboot.

I was using 05/07 build so that explains that. Im using TWRP 3.0.3.0 Kipper, but i can't find newe TWRP builds for the wileyfox storm, if you could give me some links that would be great. Stock rom was android 7.1 i believe and bootloader version is 'kipper-N-g2253387'. When i installed AEX via my (probably corrupt) TWRP recovery it says it also flashed Magisk but once the phone starts and i go to the magisk app it says im unrooted and so does rootchecker say. I think my biggest problem is with the TWRP recovery. If you could get me the download links of the versions your using that would be great.

Here you can get TWRP

Thanks to kligli from 4pda
Maybe the bootloader from 7.1-wileyfox is not compatible with Lineage OS.
Before flashing TWRP and LOS, I rolled back to COS 13.1.5 official Wileyfox ROM via fastboot. So I don't really know whether it is compatible or not.

So i flashed the twrp 3.1 and that works, it installs gapps now and no error with lineage OS, im gonna boot phone soon hopefully lineage will start to, i didnt know what gapps to flash but i tried the arm64 because i read it somewhere. But isn't the Storm ARM?

Use ARM64 - 7.1 - nano or pico GApps. Lineage official site said it works even without any GApps, but I have not tried that.

So I just bought a wileyfox storm few days ago and am on 7.1.1 what is the rooting method thanks.

XePeleato LineageOS for 4X (Kirin 620) Discussion

Hi there, as can you see here https://forum.xda-developers.com/p8lite/development/xepeleato-s-lineageos-14-1-t3542120, from @XePeleato, he did a LineageOS ROM for P8 lite but he want to help us too, so read the post slowly and if you want to test it, go ahead
In Which phones works?
Che2-L03,Che2-L11, Che2-L12, Che2-L23, Che2-UL00, Che2-TL00, G735-L03, G735-L23
Downloads (Always thanks to Xepeleato for helping us, Really)
Experimental Build 1: http://hisiliconroms.pw:8080/4x-1.zip (it doesn't boot)
Experimental Build 2: http://hisiliconroms.pw:8080/4x-2.zip
Installation Instructions (PD: it is hard)
First of all, you need or XePeleato TWRP for P8 lite here http://error404software.com/android/recovery.zip, or TWRP 3.1.0.0 (custom) from Roman Horulsky here https://mega.nz/#!FxwWjJxA!KrLvc85QD9w97ECX3kNRHM5LLWdGLVQix524JnPk5Og
Go here and get the appflasher https://forum.xda-developers.com/honor-4x/how-to/install-emui-4-1-4x-4c-g-play-g-play-t3515702
On http://hwmt.ru/oth/HWFF/info/view.php?find_model=ale-l21 download any rom that is says FULL, and add it to appflasher with the instructions in the post above
On TWRP Mount everything and install the P8 lite ROM (install ZIP)
Then on TWRP. reboot on Bootloader and Install TWRP again
On TWRP, go to Wipe, but before anything, FORMAT DATA (NO WIPE), why would you say? because when you install a p8 lite rom the phone encryptis itself and you can't use/wipe data, and emui data IT IS NOT COMPATIBLE with LineageOS Data
Wipe Cache, Dalvik, Data, Internal and System
Then install the zip posted above
Bugs ATM
Doesn't work:
No RIL on Single SIM Phones (on Double Sims RIL Works)
No Sound
No Bt
It seems it detects the sd card (you can enter to install things and everything, but only from the notification), in short words it isn't visible in media apps
When i connect the headphones the phone doesn't detect it
Record and see videos (.mp4 files)
Can't confirm, but maybe OTG (all of us the testers don't use it)
What works
Wifi (perfectly)
Camera
it seems GPS works
Install apps from explorer
Play store (it shows all the apps)
Dev Options
No problems with root (it needs to be flashed)
Many thins more
You maybe are wondering, why it doesn't boot on G Play/4X, or it has some sort of Wifi Bugs on G Play Mini/4C? because the net card, P8 lite (and probably 4C too but with different model) have a Siliscon Net card, and we 4X users have a Broadcom Netcard, so the romitself it is trying to load a module for a hardware that we don't have, so it doesn't boot
I did this post here, so we don't inundate the P8 Lite topic
if you have questions about this, it is your time to ask! (and if you are a dev, your help is appreciated)
EDIT: first experimental builds are up, see the 3rd page on comments (added pics)

Alright, so later on I'll build a special zip with a compatible kernel. This is going.to be the workflow.
1) You are interested and send me a PM
2) I send you the zip
3) You answer with your device model and whatever you think it's important like:'wifi didn't work, here's a logcat when I try to enable it's
4) I send another zip...

IT'S NOT POSSIBLE TO FLASH ON CHE2-L11
I have followed all the instructions (slow method), but flashing is not possible on my Huawei Honor 4x Che2-L11. It stops in the flashing process.
When doing adb sideload, it fails with the error message:
Code:
"E:unknown command [log]
Updater process ended with ERROR: 7"
(this is error message in TWRP, not on laptop)
I have never succeeded in installing CM before, so not surprising that I can't install LineageOS. Nobody has taken care of Che2-L11 so it's total uncertain situation while some claim it works but don't show how. I have followed all the advice, tried all the different TWRP versions, but it always got stuck on "patching system image unconditionally" (with CM 12.1 - P8Lite version). Probably reason might be that they are not wiping everything, but keep some partition but forget to tell me about it. I wipe everything.
We need some common effort to make Che2-L11 versions, work together. I can do my part if we cooperate.

As I said, this is a discussion and not the ROM itself, the ROM for 4X isn't available yet, anyways I put these instructions so you can test it, and your error isn't normal
If you want to try, get the boot.img and flash it, the phone won't boot
I made this discussion for people that are interested on lineage OS and want to try the experimental ROM that will be here soon
And it is weird that cm12.1 failed to you too, me with other users already installed other roms, like this one or cm12.1 and it flashed well
All from us for Honor 4X Che understand your frustration too, since even the other devs here of the 4X (che1) ignore us, but at least now someone want to help us,so we need to support him
And yes it is sad that even a dev from other phone is helping us, the only dev we had sold his phone

Thank you for the answer. Can you tell me what you wiped before flashing the CM 12.1? How did you perform the wipe? With format? I think there must be something remaining when you flash CM 12.1, which I am wiping.
Maybe I am flashing the wrong rom. I don't know that there exists any rom of CM for Che2-L11. The one I am flashing, I had to change the update-script to remove first line. Where is the CM12.1 for Che2-L11? I don't think any exists.
I fully understand the situation with lack of devs. I think it can be improved with some better documentation, for example we can make a separate thread here.

When I install custom Roms, first I install any p8 lite ROM (emui) then flash it, and then I have no problems
Sent from my Che2-UL00

So I should download the rom zip from p8lite thread and pm XePeleato for a compatible kernel for it to boot? Sorry but there's too many instruction. I can't follow btw I'm on b515. Should I use a p8lite rom for it to work?

@ericotena for now he want to test that we users with 4x, all of them doesn't work to see rare things, for example an 4X working
i mean yes download atleast the zip now, and try with those steps, personally i tested using 4X and @MarcoPLs with P8 lite rom, and we made it to test
Xepeleato said it is enought that if you quote him in 1 comment, so he will pm you then with a rom

@XePeleato I want to test it too when it is available haha. Thanks for your efforts on this rom!!!!

@XePeleato I really appreciate your great job and I wish you can help us , our poor Huawei honor 4x users :laugh:

Don't worry, I couldn't PM you yesterday because the build didn't finish (nothing I can do about it). As far as I know, the ROM has to be compatible with Che2-L11, but if there's other more 'compatible' model I'd like to know it, like the ALE-L21 for the P8 lite.

[UNOFFICIAL][8.0.0]OREO[LINEAGE-15] Not booting up

Well you all would have already know that-↓
Lineage 15 is released for our Z2 Plus and is also available for download
I tried to install that rom
But I was getting error 7 and then error 6 !!
But Somehow I managed to get rid from it installed the rom successfully as well as gapps but it's not booting up
:crying:
And yes I how did I manage to install it?
I was getting error 7 and error 6 then I opened the "update script" file into the rom and deleted all asserts coding and even then it did not work. So after trying for 2 to 3 times it installed easily but was not booting up.
Just want that if you guys can check it and somehow it boots up

How did you finally manage to install the rom? Did you succeed? You did not write clearly. And where are the files located?

Wait for Oreo releases of the XDA Devs here instead of flashing untrusted stuff from the internet.

Z2 Plus is not officially supported by Lineage OS for now, so possibility of getting early builds is kind of unlikely, so please verify the source of the download once and refrain from flashing anything thats not released by our devs for now

I am new to XDA and That's why I was not permitted to add any external link to the rom (files) itself.
If I still can add external link so please tell me how to do it
And yes I how did I manage to install it?

calm yourself and just gently show patience.
the devs here on XDA are working on Oreo, check the Offical AEX thread, Davide stated that the next build is going to be Oreo.
I wouldn't flash any ROM without having the ability to see the source code atleast. The site you found the ROM at does not look legitime to me at all.
Who knows what it will do/did to your device.
I mean if you dont care..

"B2017GV1.2.0B13" EU stock TWRP flashable ZIP ?

I have a problem with Lineage 14, a lot of ghost touch and problems with Nova launcher.Since I'm a stupid and didn't TWRP BEFORE installing Lineage, and since I was lucky with a "casual" driver install (as said in another post, tulip worked only after I installed a Lenovo Qualcomm drivers), in a nutshell, does somebody has "B2017GV1.2.0B13" EU stock flashable ZIP to avoid to reinstall TWRP? Maybe can someone make a backup of his stock clean B13 system with TWRP and share? Thank you very much!

Mod Edit: rude quote removed
I trust in mods, I know that IF this could be the wrong section they will move it.In the meanwhile I got a "thank you" in less that 24 hours from the post so maybe I wasn't that stupid posting here and other people are looking for the same in the same section...

Yes, your question belonged in the "Q & A" section (I moved it to the correct section).
And yes, it is rude and a violation of Forum Rules to insult other users. The currently is no rule stating you can't call yourself stupid, but there is a rule saying you can't call someone else stupid.
Before pointing out the rules to other users, make sure that you are following all the rules as well.
If there is ever any doubt about what gets posted where, or what is considered a violation of the rules, EVERY section has the rules listed at the top.

Thank you, but as said I was so randomly lucky installing TWRP -due to some driver issues- that I need someone that could make a nandroid backup with TWRP otherwise those official update files will erase my actual TWRP recovery
Anyhow, the Lineage 14 guy is allready working on lineage 15, so maybe I will whait and try the new lineage, maybe in the meanwile I will try other roms.
Actually I don't know if it's the lineage 14 problem bounded to my hardware, I had not this problem before installing it, maybe those ghost touch will remain even after flashing a nandroid backup of B13.
Anyhow if you ore someone else will install TWRP what I need it's just a nandroid backup (without you apps and you stuff, obviously, hehehe)
Thanky you.

Dear ris, I really appreciate your serch, but if you read the entire thread (4 posts) you'll find that someone else already posted the link and THAT link is to UPGRADE to B13 with the official recovery, is not a .ZIP flashable with TWRP recovery.
I think I was pretty clear in the thread title.
I just need someone with TWRP that can make a nandroid backup of a clear B13 and post it, so I can flash it back with TWRP.
Thank you for trying anyway, but it looks like I'm not able to explain myself or pople tht have Axon 7 Mini are new to TWRP and nandroid backup
In the stock thread they removed the stock recovery link since is very dangerous (?) so I can't even come back to stock AXON 7 mini with that file

Ok flashed B12 EU from other thread and the missing recovery.img (removed since dangerous) was flashed with twrp from the B13 upgrade.Than the phone was stuck at ZTE start logo, I update with SD and recovery to B13 and everything went fine, no more ghost touch, I'm afraid is due to TWRP or magisk, since now that is 100% stock I have no more problems! Wil try to root with tulip and patched boot from magisk, let's see is the problem is the root or the TWRP in European version from g&arbest so OP, you can close the thread, and thank to people who try to help!

Do you by any chance still have a copy of that update? All ZTE update sites are down. I really need to flash a stock rom and can't find one. B12 will do the trick too...

Can you just downgrade OOS to Android 10 and then flash TWRP or is it impossible?

Hi, I recently bought an used OnePlus 8 Pro and it was already updated to Android 11. After repairing it, I discovered that it's not possible to run TWRP on this firmware version.
Couldn't I just go ahead and downgrade the OS in order to run TWRP on it or is it basically impossible like on the latest Samsung Galaxy S-series devices?
Would be glad if someone could answer me that question. I kinda tried to boot into twrp because I was too quick to read the thread but it just caused my device to run into Qualcomm Emegency Mode.

What do you need twrp for? If it's just to root and almost everything else... It can be done via other means.

Hmmmm the way I've seen a lot of custom roms... They're installed/flashed partition by partition in bootloader via fastboot.....I guess if you have to use twrp to flash the entire rom you do need to downgrade to os 10.

Thank you for your response. i think i just did not catch up the latest progress. Would you please help me find the instruction about how to flash rom in the new way you mentioned ? thank you so much.
And i still have the same question , is it necessary for us to downgrade to android 10 and then start flashing rom.

Look at the roms in the subforum here:
OnePlus 8 Pro ROMs, Kernels, Recoveries, & Other
Improve your OnePlus 8 Pro 's battery life, performance, and look by rooting it and installing a custom ROM, kernel, and more.

I just looked at some popular ones like Pixel experience and Lineage and they're both flashed in this way. Look at the opening post where the instructions are... Seems like Pixel Experience there's a batch file that flashes the partitions but it's essentially done this way without twrp.

thank you for your reply, I already tried to flash pixel experience, i followed the install guide but failed to flash its recovery file.

Because it requires installing rom from recovery, so I get stuck here.
The problem is the device enters crash dump mode when switched to recovery mode. I guess the reason is that my p8pro is in andriod 11 before i flash recovery. now the device can enter android 11 normally but the recovery don't function. So I am here to ask is it necessary for me to downgrade to android 10 to solve the problem.

Thank you for your reply, it help me a lot. i have already flash my device lineage os . Regarding the problem i mentioned in my last reply, it seems the install guide is for android 10. As for android 11 , i think it needs a payload dumper to extract all files and flash them one by one.

Hi, I recently bought an used OnePlus 8 Pro and it was already updated to Android 11. After repairing it, I discovered that it's not possible to run TWRP on this firmware version.
Couldn't I just go ahead and downgrade the OS in order to run TWRP on it or is it basically impossible like on the latest Samsung Galaxy S-series devices?
Would be glad if someone could answer me that question. I kinda tried to boot into twrp because I was too quick to read the thread but it just caused my device to run into Qualcomm Emegency Mode.

I think the answer depends why do you need twrp. If you just want to flash a rom like me, you can find a custom rom supporting android 11,for example lineage os and you can flash all files it requires without twrp.
If you want to flash a android 10 rom or you just want to flash twrp , i don't know how, maybe you should downgrade.
