As most of you know, the bootloader unlock server for the rest of the world is down and Lenovo is not fixing it and even worse they are not even giving us updates on the issue. This has been going on for 1 month and 10 days now, longer than most of us are willing to wait. A lot of users already sold their phones and bought new ones but for us who decided to stay, we are at the mercy of Lenovo. This is why the petition is started, we want to unlock the bootloader and at least an official statement.

Even if you already unlock your device, please help us, by taking 5 minutes to sign this petition so we can apply pressure on Lenovo. The more the better so please share this post with your friends, family and the internet (Reddit, web forums, etc.)

https://www.change.org/p/lenovo-lenovo-deny-possibility-of-unlocking-phone-s-bootloader

Any help is welcomed.

Personal note :

As a broke student, I can't afford to buy a new phone so this is the only way for me to try to get Lenovo to fix the issue as soon as possible. I really do appreciate any help we receives.

why were u a lazy azz when u had time to unblock ,whose responsibility was it to unblock??

isnt it a unwritten rule or a rule of thumb that mobile enthusiasts or custom ROM lovers to root their phone after 30-40 days of use . there is no way that lenovo is going to keep servers on again ....enough said i done my part have signed up for petition
[Lenovo P2 Guides, News, & Discussion] ykcmaster:
Warranty my friend, not everyone have the money to repair their phone if it breaks. Plus I didnt think of unlocking because there arent many trusted source of rom but since lineageos was released I wanted to unlock it.

"Trusted sources of roms"

What's that meant to mean? Subham and firelord have made many stable Oreo roms already
[Lenovo P2 Guides, News, & Discussion] ykcmaster:
It meant what it meant. Stable != secure. I am just taking possible security steps. If it was an android expert I would have read the code and compile the roms myself if it wasn't bothersome.
[Lenovo P2 Guides, News, & Discussion] b50corei5:
-_-

Mate, these roms are all 100 percent stable
[Lenovo P2 Guides, News, & Discussion] Silliarse:
Why lenovo do that **** bootloader server unblock, it's bad for us it's bad for them, more people who unlock bootloader is less people with warranty.

Maybe someone have a method to force unlock the bootloader, infortunately I can't help mine is already unlocked.

Petition signed, hope it help !
[Lenovo P2 Guides, News, & Discussion] ykcmaster:
Hey, no they are not. Are you claiming that every ROM ever posted on this forum is 100% stable? If so I'd like to see you support your claim.
[Lenovo P2 Guides, News, & Discussion] b50corei5:
Yes I am.

Los 14.1 is the same if not worse stable then roms from firelord/subham
[Lenovo P2 Guides, News, & Discussion] ykcmaster:
https://xdaforums.com/lenovo-p2/development/7-1-2-beanstalk-rom-lenovo-p2-t3614921

This rom is in beta not stable. You lose.

oh and just incase, here is the latest rom from subham

https://xdaforums.com/lenovo-p2/development/rom-lineageos-15-1-t3787299

Surprise, surprise, it is beta not stable.

stable != secure

and

there is never a 100% in everything, even if all the roms here are in stable status, it will never achieve 100% stability.

LineageOS 14.1 is better than the rest of the unofficial roms here because

1. The code have been audited.

2. The images are compiled by a trusted source (LineageOS team), unlike the rest of the rom here which is mostly compiled on someone's computer then uploaded to a hosting site.

3. It is stable enough to be an official rom.
[Lenovo P2 Guides, News, & Discussion] b50corei5:
Mate, I don't think you get how it works. Beta does not affect stability or not. Everything that works in los 14.1 works in subham/firelords roms.

Point 1 is absolutely bullcrap, I suggest you do some research.

Point 2 is bullcrap too. The thing that complied the rom doesn't affect the rom. Mike compiles on a computer as well. You think he has a supercomputer or what?

Point 3 doesn't matter. Official is just a tag.
[Lenovo P2 Guides, News, & Discussion] ykcmaster:
The status does mean something. It means that is is not stable enough to have the status stable. How could a buggy software be considered stable?

Point 1 : What do you think Gerrit and Open Source is for? https://wiki.lineageos.org/usinggerrit-howto.html

Point 2 : You missed the point here. It is not what compiles it. It is who. Just because the source is clean doesn't mean the build is clean. Assuming you trust the developer, A lot of the ROM here don't even provide PGP keys for you to check if the ROM is unmodified in transit! How could that be secure? https://android.stackexchange.com/questions/189063/how-can-i-trust-roms

Point 3 : There are requirements to be an official ROM. One of it is be stable enough. https://wiki.lineageos.org/submitting_device.html

Please do some research and have some common sense before you open your mouth.

So far you have not supported your claims that all the ROM on this forum are 100% stable. You can never prove that point because nothing is ever 100% even if all ROM here are stable.

When you say debrand / remove retail mode?

My phone currently has a locked bootloader (I have the code from Huawei) started out unlocked, with no branding, after putting in a Three UK sim I now have a Three logo everytime I boot up and a factory reset, reinstalls some Three apps and sets my web browser home page to three.co.uk. Would this reset the phone to before I put that SIM card in and gave it that branding.

from the downloads there is only one file name 'oeminfo'...also it has no extension i.e. .bin

---------- Post added at 09:14 PM ---------- Previous post was at 08:56 PM ----------

amazing...this works, im now on C432 120

Many thanks...instructions work to a T, but i would clear up the steps 6,7,8 as they may confuse.

This my first huawei so im slowly learning, i have nexus's, samsung and sony before so the huawei are new to me.

If for some (strange?) reason i wanted to go back to c732 (UK) how would that be done? would you mind sharing the method?

Also would it be a good idea to save the existing oeminfo in case someone wants to go back? or are these downloadable from somewhere?

Also I would to the instructions root is lost and how to re root the new firmware, factory reset wipes all data and if bootloader is locked or not (i dont think it is but OEM unlock is greyed out).

Many Thanks again.

EDIT: Root after update can be obtained via TWRP as that is now available for p20 i guess? someone confirm?

I wanted to try to replace this with the original one and then use the twrp method but putting nobrand software. This oeminfo is from the CLT-L29 Nobrand right?

[Huawei P20 Pro Guides, News, & Discussion] dlads:
What do the files actually do that we've flashed? I'm just wondering?

Would also help to know specifically what you're flashing, would help people who don't know (like me :D ) in future should they be needed again.

eg: recovery_ramdisk_nocheckP20.img does this stop the system from checking if there's a custom recovery installed?

---------- Post added at 03:34 PM ---------- Previous post was at 03:29 PM ----------

As far as i'm aware, this huawei device doesn't have an efuse chip, i could be wrong,but it does say bootloader- 1 within the bootloader, can't remember exactly if it said anything else prior to bootloader unlocking on my device, i would assume so.

You can re-lock the bootloader for updates but warranty i'm not sure, if they can identify it and they want to act like dicks then i suppose they could refuse on those grounds.

Would be great to be able to go back to complete stock if needed.

All 2 sim work correctly ? Also data ?

All 2 sim work correctly ? Also data ? : Recognize the 2 sim, but I have not tried (yesterday was very late) the connectivity.

With the thread manual I changed the model (Old: L09 C432), but I did not recognize the 2 sim. Use the payment method by funky, and I got it (formatting data several times) but I blocked the boot and it does not work the unlock code of Huawei (I have also checked that I have not changed the IMEI).

Thanks for answering.

I've followed the steps but when I get to 8. i get 'no devices/emulators found.

What am I missing here?
[Huawei P20 Pro Guides, News, & Discussion] suicidal.banana:
Hey all, sorry if these are stupid questions but im like 'better safe then sorry' as i literally got this phone only a few days ago. Long story short, i too bought it expecting dual sim, only to find out its single sim. So can i, or can i not turn this into a dual sim phone without causing the bootloader to lock up? reason i ask is because first post of the thread says no in big bold red letters, but then some posts say yes, and going over the last few pages of the thread the succes-rate of this seems to be all over the place.

Do i just follow the guide posted by dladz here? or do i need to do additional steps before or after (not mentioned in the guide i mean) to get said dual sim capability?

Also where exactly do i get a dual sim tray at? do i just email huawei? i also read somewhere that appearantlly they are showing up in chinese webshops now aswell, but did anybody compare those to the real thing yet? i dont really wanna risk the splash protection of the p20p.

Also wondering if i need to do the whole guide dladz posted as my p20p doesnt seem to be branded (while there was some bloatware theres no branding from my provider, T-Mobile, and im in the Netherlands where theres generally very little provider branding on smartphones, i did download some provider package the first time i turned it on but fairly sure that was just settings for sms cb etc)

Thanks in advance :)

8 on which guide 152 or OP

---------- Post added at 11:19 PM ---------- Previous post was at 11:13 PM ----------

Hi there,

For me I've not got the sim tray which would let me see if the phone does indeed allow dual SIM so I'm not sure personally.

That being said I don't believe either guide on this thread will give you dual SIM, as stated in the OP in large red lettering :D ;)

it'll just change model and variant IE: L-09 c782 to L-29 C432

The reason i'd stick with this guide is because it's free, which is nice and your bootloader won't lock down as it may / may not with funky which is great because you may or may not be able to get another unlock code.

If they're unlock codes are still available then I'd assume Itd be safe to use them.

They're meant to be friendly and knowledgeable but again they really ought to be for the price they charge.

Perhaps contract them and clarify what's on offer and if they guarantee functionality, it would make sense before committing.
[Huawei P20 Pro Guides, News, & Discussion] suicidal.banana:
Cool thanks for clarification :)
[Huawei P20 Pro Guides, News, & Discussion] dlads:
Aldi be careful with Chinese kit, there's a water proof seal on the sim tray which I wouldn't trust from them.

I'm looking to get from CLT-L09(C782) to CLT-L29(C482) for EU updates but don't want to change HW for dual SIM. Does following this guide achieve that or are people getting mixed results when changing the region (says in OP: DONT TRY TO REBRAND L29 to L09 or vice versa will brick or have problems ! EDIT:SOME PEOPLE TRIES AND IT WORKS FROM L-09 TO L-29)?
[Huawei P20 Pro Guides, News, & Discussion] colthekid:
So just go to CLT-L09(C432) then. Just put step 16 as ./oeminfo CLT-L09 C432 hw/eu.

Ah I see. Have you done the process yourself?

Also are writing to oeminfo? Doesn't that contain our IMEI?

Yep, worked fine. No IMEI is stored elsewhere, usually in non writable memory
[Huawei P20 Pro Guides, News, & Discussion] matt4321:
I see. One last thing, if I'm sticking with CLT-L09 and just wanting to change the region to C432 from C782 does rooting to begin with in the first few steps change, since the instructions say 'Rooted with ramdisk-CLT-L29-MAGISK.img fastboot flash ramdisk CLT-L29-MAGISK.img'?
[Huawei P20 Pro Guides, News, & Discussion] colthekid:
Yep root your C782 . I installed TWRP & flashed Magisk from there. Just to be sure I used the generic Magisk Zip from the Magisk thread as the OP only provided an L29 file
[Huawei P20 Pro Guides, News, & Discussion] matt4321:
Then in regards to updating, like to C432 B131, you can just download the files and use HuRUpdater?

Could I just use the C432 B131 files in place of the C432 B120 in this thread? Or are these part of the conversion then an update is needed?

Hi guys after step 23 my phone reboot into TWRP recovery and does not rebrand
[Huawei P20 Pro Guides, News, & Discussion] colthekid:
Yes to the HuRUpdater for subsequent updates. I used the B128 files for my rebrand. With the odd exception (updating to P when it arrives etc, you can usually use any full rom (not OTA) to update from any previous one, you don't usually have to do them in order (i.e. you could go from 120 to 131 directly)

I don't know pal, again I've just stuck to what I know works, it's certainly not a negative effect as my phone works perfectly, and who knows, in the future I may buy or mod my sim tray, apparently it doesn't show up as a second SIM until one is actually in the device.

Really odd the way Huawei did this, lol just make one device and let people have it.

The lack of devices in the US too? Lol don't they like money?
[Huawei P20 Pro Guides, News, & Discussion] :
I converted CLT-L09 to working dual sim CLT-L29, both c782 using funky huawei. I heard using this method the original huawei bootloader code would still work.

Also it says dual sim wont work on your guide but as I already converted to working dual, will that still be the case using this or will it somehow switch me back to single sim?
