Huawei Honor 6 Plus unlock bootloader without ID

After an attempt to update my android version from Lollipop to Marshmallow (from B334 to B503) my phone entered in a boot loop and I tried to flash it back with the SD card method but it failed, and I had to flash it by adb, but with a locked Bootloader I couldn't either, and since I can't get my phone to reboot into android to enter the code in to the dialer to get the ID code to use it in Huawei website to get the unlock code, I stuck at this stage for more than 4 days in the boot-loop and i tired several applications that supposed to provide the product ID, such as Huawei Product ID generator and others , in addition I emailed Huawei trying in vein to get it.....with no use, finally I found a piece of magic it is called Huawei hacker tool, and it finally provided me with the right ID and consequently i was able to unlock the bootloader

Leagoo S8, ROM and rooting

Hello
So i will get a Leagoo S8 phone next week, switching from a redmi note 3, and i am planing to root it instantly becouse i heard there are some bloatware apps and i will instal a custom rom onto the device.
Upon searching the forums and the interwebs i found no tutorials / resources that would lead me in the right direction. I did find a tutorial for Leagoo M8 ROM on here but will it work on S8?
So i hope anybody here can help me.
Cheers

Bootloader is locked. There are no solutions to grant root now.

I have a Leagoo T5c, and I found that option in Developer settings too, so if it is self-explanatory, then bootloader should be unlockable, right? I too would like to root my phone, but contrarily to the S8, that uses a MediaTek SoC, mine uses a brand-new SpreadTrum chip, and I'm not sure it can rooted at the moment.

updated mine from LEAGOO_S8_OS4.0_20171107 to LEAGOO_S8_OS4.0_20180227 and its working fine.
less heat, less lag, camera less grainy indoors (before was grainy but great outdoors, now its both great) curved display was fix(no need for rounder apps) but i was still unable to root the phone (would be great if it was rooted so i can remove apps rather than disable them and tune things up)

If a root solution is found for Leagoo S8 will it be possible to applied it to the Leagoo S8 Pro?

found this but not sure if this will work on our devices (leagoo s8,s8 pro) but if you have downloaded the firmware you may flash again if you bricked it. try at your own risked. it says there how to back up root and port twrp for ur device.

can you confirm if the boot-verified.img
inside the firmware of leagoo s8 that i download can be used for magisk to be patch and flash it through adb? thanks

From what Ive found, modifiing any of the boot or recovery files will screw up some verification, then youll have to format and flash the whole rom again possibly getting a NVRAM Warning error. So, does anyone know a way to verify(?) the edited files (boot.img -> build.prop(or default.prop?)), or any workaround? Also, I think that the bootloader kind of worked in the Leagoo OS version that came with the phone (althrough, I tried to unlock the bootloader then, it showed YES/NO and warnings like on any good phone, except that the YES selection did NOTHING, the bootloader stayed locked no matter what), havent you guys by any chance updated from Needrom?(I did) I think that the newer version had removed the bootloader completely. Someone should post the first stock rom version if you have it.

I think that in order to flash any modified files, we need to generate/verify all of the files.
Anyone any ideas? What file/s is/are the key to verifying flash files? Or is there a code somewhere in every flash file (recovery-VERIFIED.img, boot-VERIFIED.img)?
Why is Leagoo so damn good at making those things hard to unlock. As I said before, in the 1. version you could at least access (broken) fastboot, now the phone just turns off when accessing fastboot.

latest firmware with user debug possibly can extract root
latest firmware userdebug..possibly root solution can be extract..

New device : Gome K1

Hi,
I am a little new and don't really know about this subject but :
I purchased a new phone : a Gome K1.
This is not tablet but phone. This is a new brandt. This a MTK (MT6757).
For the story, it came to me with chinese ROM, all menus in chinese
I asked to the seller to give me a ROM with playstore and french. They done it.
I flashed their new ROM with a proprietary flash tool. Now I have a android 6 ROM with Playstore, french menus. Well !
But I'd like to know if there is a way to root it, and install a TWRP :
The ROM came with bootloader locked and no recovery. It is entirely blocked.
No way to unlock bootloader via the general way (fastboot oem unlock --> unknown command)
I read some articles that deal with spflashtool and porting TWRP, but I'm new to this and I don't think I will be able to make all these steps correctly to flash a TWRP ...
Does someone has an idea ?
Is my post on the good topic ?

Up, does someone have an idea of how to root it ?

Hello,i also have a Gome K1 phone and I am also interested at rooting it.
There is an ' OEM unlocking option' under the developers option in the settings, have you tried that yet?
If you managed to import twrp and rooted the phone can you pls send here the steps, Thanks

Hello, happy to not be alone with this phone ...
Yes I tried everything, after enabling unknown source, OEM unlocking and USB Debugging developer options :
- All root apks
- all existing root kits using ADB
- Method with a linux distro to access Phone filesystem as root ( cannot see my phone ... )
Now I'm trying to use SP flashtool last version, but even that cannot correctly access the phone to Readback my recovery : there is BROM error, so I think that phone is not compatible with the phone (seen on a forum ...)
So if someone has an idea, he is welcome

When I contacted them, they send me a non rooted custom ROM which embed Google Apps and All language, AND another flash tool.
This flash tool seems to be based on SP flash tool. It seems to have restrictions (no readback ability ...).
I'm not able to backup anything with this tool or with SP flash tool.
Whis spflashtool, when clicking ReadBack, I power off my phone, and plug USB cable.
It begins the process but I immediatly encounter a BROM error :
ERROR: status_brom_cmd_send_da_fail (0xC0060003)
I read a post which indicate to try to plug usb cable when pressing Power plus Volume Up, but I don't think it can work, because I know that their tool works without that operation.
So now I'm still stuck here. Does someone have an idea ?

Hi
On the Russian forum 4pda, the topic GOME K1 we are also discussing and trying to solve the problem of a locked bootloader. So far no results. ROOT is also not yet possible to get.
I've also ported twrp for GOME K1, but there's no point in installing it until the bootloader is unlocked. Otherwise we will get a brick.

Hi
In Developer options there is a setting to unlock bootloader, it's the third toggle down.
Hope this helps.

Hello vsxby,
I was successful in flashing custom ROM that vendor uploaded for me.
So I thing I can flash just the recovery with their tool. I'm not an expert, so I'm just a little affraid to follow a guide to port a TRWP for Gome K1 and try to flash it, since it can brick the phone.
If you want, I can't send you a copy of their tool they sent to me (SPMultiPortFlashDownloadProject.exe) ...

Thank you, but I already have this tool. As I wrote before flashing TWRP we need to unlock the bootloader. While this is not impossible to do. But one of our users on 4pda is going to ask the manufacturer to unlock bootloader. In case of success, I will inform you.
If you want to experiment and flash TWRP with a locked bootloader, I can give you the TWRP I made, but I warn you, it's not safe.

Bro,Can you upload the firmware and tools to google drive or something like? It will be very helpful for dealing with this mediatek replica phone(aus6757_66_m),i got some possible factory test MTK AOSP,but the link expires ：（

I used your tools in the windows 10 lap. and also in the windows 7 lap but it was useless. I am going to try the procedure in the windows 8.1 lap. can you tell me exactly how you flash your phone with that tool ?

Xiaomi mi 10 lite youth edition/zoom

Hi, Guys
I got a Xiaomi Mi 10 LITE YOUTH EDITION better known as the ZOOM EDITION in China, The reseller flash a EEA Global ROM on it but the camera on this version does not seem to work properly due to the fact that it's got a 50x zoom lens, so I wanted to flash the original CHINA ROM that came with the device! So by mistake I flashed and locked the bootloader at the same time! The image did not take and the bootloader is locked, only to get a message This MIUI version is not compatible on this device! Weird because it is a CHINESE ROM that needs to be on the device!
Long story short I am stuck in Mi recovery Mode and can only use Fastboot as well! When I try to unlock the bootloader it says please switch on device and go to developer settings and select Unlock status. (Which I cannot do now)
Is there anyway to unlock my bootloader besides opening the deivce or paying some random person to access my computer and hopefully fix it!
Am I screwed now?
Some help would be appreciated
Thanks in advance

you can try Xiaomitool v2 and choose the 2nd option : my device is bricked, i want to unbrick it.

Hello
You have to use the "miflash" software and flash the original rom I give you the link (https://bigota.d.miui.com/V12.0.3.0...VCNXM_20200620.0000.00_10.0_cn_cd89596665.tgz) you have to download it, decompress it and then put it in the software, put your phone in fastboot mode and click on " flash" sometimes it's long, you have to let the phone turn on again, and then you can unlock your bootloader Good luck

Hi, Im interested in purchasing this Zoom/Youth versión, where did you take It, please?

If reseller flashed your device before it means your device was unlocked. I bought my device from eBay. It was unlocked and it was advertised like Chinese version of Global ROM , camera was not working properly as your one. So I used my computer to install Android adb,TWRP and I flashed my phone with TWRP recovery from the xiaomi.eu site. Your device name is vangogh. Good luck.

Try to use Miflash tool and find Chinese original ROM for your device (Mi 10 lire Youth Edition - vangogh is a code name) flash it in Fastboot mode, then unlock it (you have to sign up for Xiaomi account to do this) it might take some time. After that you can try to flash it via TWRP

To many threads, what are the steps to change the original OS ?

Hello all,
I have read so many threads, and finally I'm still not sure to have the right method.
My current config has no more memory to update apps so I need to do something ! Here are the details :
Huawei P8 Lite 2017 (PRA-LX1)
build : 8.0.0.402 (C432patch01)
EMUI : 8.0.0
Android : 8.0.0
After reading several threads, here are my questions :
1. I have to use DC Unlocker --> is it always mandatory ?
2. Which TWRP do I have to use ? (link please, I'm completely lost, an still doesn't know which one to download ! :angel: )
3. LineageOS 15.1 seems to be the best choice (battery stamina), does it work perfectly ? (GPS, camera...)
4. What about Treble Project ? I still doesn't understand it is a better idea, how to install it, which ROM to use...
Thanks for all of your replies !

Hello,
DC-Unlocker is mandatory if your bootloader is locked. Recently, TWRP went official on P8 Lite 2017 devices. You can grab it from the official TWRP website (can't post links as I am a new user, search for 'prague' in the device list). I am using LineageOS 15.1 on my device and it's working flawlessly.

I use chimera to unlock bootloader.
But every custom to a have to flash isn't work. Boot loop or other issuses, like "device is uncertificated" so any google apps don't work.
Do i need to decrypt memory? To flash corectly custom rom.
Finally i have only root, and clean all brand apps.

1. Download DC Unlocker from GPlay, buy credits (it will send you username and password to your email)
2. Download DC Unlocker to your pc, in phone allow ADB debuging and HDB
3. Type into call app '*#*#2846579#*#*', tap on 'Background settings', next on 'USB Ports Settings' and select 'Manufacture mode'.
4. Plug your phone to PC and click on 'Detect device' and allow all stuff that will pop up on your phone.
5. Click on 'Server' tab (we are still on PC) and enter username and password you've got from app and 'Check login'.
6. Click on 'Unlocking' tab and choose 'Unlock bootloader code'. And your code should popup in text log.
7. Let's move to your phone, go to settings -> developer settings -> Enable OEM unlocking, enter your password.
8. Power off your phone and when it vibrate push Vol - and Power button at same time.
8. Plug it back to your PC and start Command prompt, enter 'fasboot oem unlock 00112233445566778899' (use your code).
9. Now just accept unlocking and formating all your data on the phone.
10. Download TWRP and let's flash it using command 'fastboot flash recovery_ramdisk twrp.img' (if your command prompt is in for example C:\Users\Pepege just cd to your Downloads directory where is downloaded .img file)
11. If it's succesfull just type 'fastboot reboot' and keep holding volume up, if eRecovery pops up click on reboot and this time hold volume up and down (idk why but sometimes works this and sometimes this combo)
12. If you are in TWRP just format DATA, CACHE and Dalvik Cache partition, make backup (if you wanna) and now flash whatever you wanna. LOS, AOSP, it's on you.
Also if you wanna LOCK (not relock) your device, download HuRuUpdater, download oldest version of Android for your model and region (C432 in this case) and flash it, after you reboot from recovery go to bootloader (fastboot mode) and type on your pc 'fastboot oem relock 00112233445566778899' then 'fastboot reboot' now do first setup, go to developer options, disable 'Enable OEM unlock', format data again (to be safe) and you are ready to go, after updating to oreo relock status should change to locked.
EDIT: Adding random Youtube video just in case https://www.youtube.com/watch?v=pclEmwt5C84
EDIT2: Project treble is simply stuff splitting system from vendor, it's on every device runing on oreo or better, more here https://www.xda-developers.com/goog...ze-android-so-oems-can-update-devices-faster/
Also for me best ROM are AOSP 10 and LOS 17.1

No custom rom wanted to boot. The method on this page will not work. All that's left for me is to decrypt the phone's memory. but then knowing that the weekend was over and I needed a phone call on Monday, I just let go.

@DunoCZ
What a great post, thank you so much !!!
Some people have reported more battery consumption on Lineage 16 and 17, compared to 15. Did you test all of these ROM ? Are there people here who have some feedback ?
@flgmnft
If I unterstand well, I need to extract fstab file from the ROM archive in order to remove the encryption : can you confirm or explain me what to do ?
@ilakhnon
It seems you don't have the encryption problem, what is your opinion about it ? did you edit the ROM fstab file ? other ?

Some people have reported more battery consumption on Lineage 16 and 17, compared to 15. Did you test all of these ROM ? Are there people here who have some feedback ?
@flgmnft
If I unterstand well, I need to extract fstab file from the ROM archive in order to remove the encryption : can you confirm or explain me what to do ?
@ilakhnon
It seems you don't have the encryption problem, what is your opinion about it ? did you edit the ROM fstab file ? other ?

Here you go guys, no need to edit it on your own

hummmmm.... bad news : my phone is not detected by DC Unlocker !
I should have tried before buying the license, but it doesn't matter.
But don't you find it strange ?

oh... I didn't read it correctly, the P8 Lite 2017 is not supported, only the P8 Lite (that was my mistake).
But I wonder if I really need it, because I bought it "sim unlocked", what do you think about it ?
EDIT : in other words, how can I know if I can erase the original bootloader ? (adb method)

Then try using hisuite to downgrade to nougat, but after unlocking upgrade to oreo to have treble enabled.

I'm waiting for an answer from DC unlocker's developper, and I will test this solution if I don't have another choice.
(I don't know if it is easy to downgrade with HiSuite, I've never used it, I will see that later).
Thank you for your help.

Downgrading via Hisuit is easy

Hello @DunoCZ,
I was thinking about this post... I won't need to unlock the bootloader if I downgade to Nougat ?
Is there a topic talking about it ?
EDIT : Sorry, I didn't read correctly your post. Unlocking will probably be mandatory, so it doesn't change anything for me.

There's no problem unlocking 2017 with DC Unlocker which I did two days ago.
Install HiSuite and run it once to be sure you got proper drivers and make sure you put USB into manufacture mode.

I had the same issue, and contacted dc_unlocker's developer. Basically, the software can read the bootloader unlock password if it just discoverer the phone's port, even if does not seem to recognize the phone. I had to go ahead an got the code, for 4 credits/€

I'm also interested in knowing what is the best overall ROM these days in terms of compatibility and battery consumption!

Hello all,
Sorry for my silence, I had to go back to work, and after a few days I was seriously ill. I begin to recover some energy, it's not great, but enough to come back here... and because my phone, stiill with the original system, becomes really too slooooooooooooow !
@buteo : Do you confirm me I can go further with DC-unlocker software, in order to unlock the bootloader without any risk ?
@All :
As @Natural_High asked, which ROM is currently the best choice ?
Thanks for your help !

You can use DC-unlocker, it's safe. I used it myself a couple of months ago too.
Regarding the ROM, I haven't tried any Android 10 or 9 ROMs. From what I've seen, people say it's still a bit too buggy, so I went for LineageOS 15.1 and it worked fine. I did some tests, since I don't use it as my daily driver, but eveything seemed to work fine! anyway, feel free to try some of the newer ROMs and let us know your opinion

Thank you very much for your answer !
Lineage 15.1 was my preferred choice, I think I will use it.
I hope I won't have any issues, since I really need my phone...
Let's go for backup...
