First: Firmware update or unlock Bootloader? - Honor 7 Q&A, Help & Troubleshooting

I'll get my Honor 7 the next days.
In the past I've rooted all my phones (till now I use a Honor 6), so I'll do this with the new one, too. I found several good threads, but one question is open:
Is it better to make the firmware update first (I think it will be send with Lollipop) or should I start with Bootloader Unlock?
Thanks in advance
-Sylvia

First update and then unlock.

@Sylvia It doesn't matter if your bootloader is unlocked, you can always update the device. But if it's rooted then it gives problem while updating.

[Q] Upgrade to .75/.76 - Future ICS

Hello,
PC Companion says that i have a new update, but i've unlocked and rooted my phone, so when the install should begin, an error pops up saying that i have a modded firmware and i cannot update it.
So, i think the same issue will go on when next week or next year ICS will be released.
The question is: what i have to do to update my XS? I've to flash the ftf loosing the recovery and then reinstall it? Doing that, i will lost all the apps and everything on my phone?
Thank You very much
If you have unlocked bootloader, you cannot update using the official method, but only through flashtool.
If for some reason you want to use the official way, you should relock the bootloader, here is the guide http://forum.xda-developers.com/showthread.php?t=1527159
As far as my knowledge goes: You could backup your apps, lock your bootloader, upgrade to ICS, unlock bootloader, achieve root, restore apps. You'll probably have to wait for root for ICS though, shouldn't take long at all.
Or at least that's how I hope it will work.
So, the faster way is to wait for a custom rom correctly packed to be flashed via recovery
Thank guys

[Q] How do I tell if I have OTA update from 18January2012

I just got the Note 2 from Newegg (for verizon) and after reading through a lot of the threads on this forum like:
How to Unlock Your Bootloader - Firmware Version VRALJB
and
[Q] Stock restore Fail at sboot.bin
and
Questions about Unlocking or Recovering from a Soft Brick
I guess there's issues with the OTA verizon pushed out and the first guide won't work if you have the OTA. Well long story short, how can I tell for sure if the phone I've received had the latest updates put on it before I got it?
My build says VRALJB, does that mean I'm good and I still have the older version? Would it say VRALL4 if the OTA had been applied?
In a related question, would it be wise to simply update to VRALL4 now, use the new method to jailbreak, and then continue on my merry way? Would this alleviate any worries of the OTA getting applied and breaking my root / possibly bricking my phone??
Thanks for any help for a noob. I tried to do research first!
You do not have the ota..... Use original method!!
Sent from my most awesome phone EVER!!!!
As stated above you are on the original baseband VRAJB so you can use the original root and unlock method. Once you are unlocked, do not take a OTA ever as you may get relocked and who knows if there will be a future unlock method. Most of the custom ROMs block the updates, but just in case don't take it if you ever get the message.
Once you are unlocked you will use TWRP custom recovery (which is the screen that will appear at the end of the unlock process). You can flash the VRALL4 baseband when you flash a ROM if you want to be on the latest baseband (flash ROM first then immediately flash VRALL4, no reboot in between). The download can be found here: http://forum.xda-developers.com/showthread.php?t=2108510
Thanks for the replies.
There's a video on the Adam Outler Jailbreak Guide that actually suggest getting the OTA first and then just doing the CASUAL thing afterwards. Personal preference or is there some advantage?
The video in question is the first one in the thread, it is titled "Jailbreak video for Windows users only!
This video desmonstrates CASUAL used with Odin to flash the Galaxy Note 2 firmware Thanks to DroidModderX" and the timeframe in question is 00:50 to 01:10
Just wondering, thanks!
No real advantage either way (the update to VRALL4 was very minor but did relock the bootloader). If you want to be on the latest update you either need to take it OTA or flash it yourself. I was on VRAJB and unlocked before the update so I only had the original method to work with. I updated to VRALL4 manually by flashing it.
Bottom line, either way will work, just make sure if you take the OTA before doing anything that you use the correct unlock method (the "new" one). The whole thing will take you maybe 10 minutes, its really easy. The video is a great guide.

Update Via PC Companion not working

Hello all.
I need some help how to update the z2 to lollipop.
I've read stuff on internet, but I simply can not do it.
The error 2003 is killing me... And I do not know what to do.
A month ago I bought a z2 for my brother and it was/is on kitkat.
Today, I bought a z2 for my father and there was lollipop already installed.
I bought both phones via Ebay.
The phones have the same Model Number.
On the kitkat z2 I cant update via OTA either.
Could you PLEASE tell me what to do?
I have read something, that my bootloader may be unlocked and I have to relock it.
Is that true? And if yes, how can I check if my bootloader is locked?
Thanks in advance!
Use flashtool to flash a stock FTF image, this way you won`t have to bother with the bootloader, unlocked or not.
If the phone is rooted OTA updates won`t work., it will say it can`t verify. And it`s true that unlocking the bootloader will cause OTA updates to stop working.

Installing TWRP without unlocked BL

Hey guys, I have a xiaomi redmi note 3 pro kate running global developer version of miui 8.
I applied for permission of bootloader unlocking on the 30th of December. Ive been waiting for over 12 days and I'm still getting the notorious "couldnt verify device" . I have tried every single tips, tricks, methods thats available on numerous forum threads. None of them work. Don't bother suggesting me a "way" to unlock my bl thats "100% guranteed" cuz honestly i've given up hope. I dont want to unlock in the unofficial way either.
I read a thread here that says it's possible to flash twrp, root and flash all kinds of roms without unlocking the bl.
Could you guys maybe guide me through what i need to do to flash twrp and root? what do i need to do?And again, I have a kate.
yeah i want too flash root and stuff's without unlock bootloader, i have SD version of RN3, btw!

how do i successfully unlock the bootloader without it unlocking again

i am getting a brand new huawei mate 10 pro returning my current brand new one as it got updated to the latest emui which prevents bootloader unlocking, how do i succesfully unlock the bootloader on the next mate 10 pro?
1.how do i prevent it from updating and ruining my chances of unlocking the bootloader Before i have a chance to unlock it, will it force update?
2.how do i keep the bootloader locked will i have to flash some other rom on it to prevent it from updating ota or can i update it ota and keep the bootloader unlocked with twrp or will it be permanently locked if i attempt to ota update after twrp is installed and after the bootloader is unlocked
3.i read that it can restore the default recovery on first boot can anyone explain this to me
since the latest emui prevents the bootloader from being unlocked i only have one chance, and if it somehow updates to the latest emui then it's locked forever, so how do i unlock the bootloader permanently without worrying about it unlocking ever again, i thought that once the bootloader is unlocked and twrp is installed then it will stay like that, but then i read that it can get overitten just with an ota update and once it updates then i can never unlock it again.

1. Set up device, but don't plug in SIM or enable WiFi. Go to settings and check patch level.
Depending on Cust of course, but generally July or later can't be downgraded (If downgrade is needed). This is due to updated bootloader.
If May/June or earlier you should be able to use HCU-client directly to get unlock code.
For example, BLA-L29C432B145 (June) can be downgraded to B142 (May) where HCU works. This is using dload firmware from androidhost.ru (requires an OTG-cable and USB-stick 8gb min or a OTG usb hub and USB-stick 8gb min).
B146+ can't be downgraded to old bootloader due to updated bootloader.
2. When you have the unlock code you can use it, always, no matter what firmware (At least as it is now, this might change in the future)
Firmware don't normally lock bootloader.
3. To restore stock recovery you would either:
Extract it from your firmwares update.app, acquired from firmware finder. This is extracted using Huawei Update Extractor.
Stock recovery is named recovery_ramdisk and can be flashed through fastboot.
OR
You can 'dd' erecovery_ramdisk to recovery_ramdisk (both partitions are the same, different 'entry' points). This is using terminal in TWRP
dd if=/dev/block/bootdevice/by-name/erecovery_ramdisk of=/dev/block/bootdevice/by-name/recovery_ramdisk
I would suggest using the update.app approach if you're not comfortable using terminal. 'dd' is a potentially dangerous command.
But your device should ship with an already HCU compatible firmware, so you should be able to get code right away, as long as you don't connect to the internet first.

can i set it up without a Connection? from what i remember setting it up the first time it forced me to connect to the internet, as for unlocking that seems really complicated, from what i saw i can use dc unlocker with the click of a few buttons so i don't quite understand these methods, so you mean this is better than dc unlocker, does that mean once i get the code i can update emui and relock the bootloader and then unlock it? no need for any software or anything once i have the code then it's like an official code so i never have to worry about not being able to unlock the bootloader again can i then unlock the bootloader no matter how new emui if i want, and what firmware will it have if it comes brand new should it have the firmware it shipped with on release?
let's say the phone comes with Before may security patch can i then easily just get the code without much complication and then it's the same code as if i were to get it directly from huawei meaning i don't have to worry about updating emui and having the bootloader locked permanently? this is all news to me as i thought you needed to use dc unlocker as a workaround and that this only works on older emui meaning if i unlock the bootloader update emui then it's locked forever.

Hcu-Client is made by DC-Unlocker, but it works for newer phones. Its the same procedure as using DC-Unlocker, and uses the same credits. Just follow the instructions found in the program.
The downgrade would only be needed it your firmware is higher than the supported ones, and still on old bootloader.
I can't say for sure the unlock code will work for all eternity, but at least for now it will work after you update (and if phone for some reason locks after update).
If it works or not on future firmware is up to Huawei. My phone stayed unlocked when flashing Pie beta anyway....
When you have the code you it will be like the official one, so keep it somewhere safe.
I'm pretty sure you can skip through the whole set up without connecting to the Internet.
I can't remember what firmware my phone came with, it might have been on C432B127 or C432B129...
DC unlocker/HCU is only to get the unlock code as Huawei closed their site to get it. You can safely update after getting it.

oh so no need for a Cable or anything after i received the code, once i received it on the appropriate firmware then i can update emui, this means anything i do doesn't do anything to the phone itself, i don't need to do any modification on my phone i just use it to get the code then i update emui like normal and then when i feel like it i unlock the bootloader with the code, so i can get the code and just forget about it afterwards unless huweai invalidates it in the future?
simply put
1.i unbox the phone and set it up with no sim card or internet skip all logins
2.i connect it to a pc and get the code through hcu however that is done
3. i reset the phone and set it up like i normally would with internet and a simcard and then update it ota
then when i feel like it i can unlock the bootloader on the newest firmware and then install a custom rom
Hello guys, I need to read bootloader code in my mate 10 pro with dc-unlocker but they write in the site "Huawei Mate 10 Pro BLA-xxx upgraded to Android 8x not supported".. what do they main? Mate 10 pro was launched with android 8.0

It means it's not supported since May/June. I guess they just write that so they don't have to investigate into which firmware exactly.
It works on May patch firmware and earlier. Some cust even works on June.
Since your signature is Italian I guess you have C432?
If so, last build it worked on was B142. If you're on B145 you can downgrade to B142. If you're on B146 or later you can't get unlock code. (at least for now)

It most likely will be then. If its B133 or even B135 it should work with DC out of the box. Just don't update before getting code

If DC-Unlocker doesn't work, use HCU-client. I can't remember if Mate 10 Pro is too new for DC-unlocker.
It's the same credits anyway, and it won't use credits if phone is not supported in DC-unlocker (You won't get the Bootloader code option anyway).
It may ask you to factory reset in HCU to get code, if it does just comply.
You will need 4 credits, which equals $4
i spoke to the developers of dc unlocker i was told they have no idea if the code will work after emui is updated, they suggest i unlock the bootloader as soon as i receive the code.

Yes, it should work forever. I say should because it's Huawei and you never know if they decide to lock all unlocked phones and make the unlock codes invalid....

It should work in updated EMUI, atleast in Oreo.
What Huawei did, what I found out anyway, that made unlock code generation not working anymore is changing the key needed to generate it.
It's the same with the backdoor they use, it needs a new key to work. So technically all old unlock codes should work as the end result when generating an unlock code would be the same regardless of what key is needed to generate it. I guess anyway.

B145?
If so you have to downgrade to B142, firmware is available on androidhost.ru.
You will also need an otg cable and a memory stick/usb adapter and minimum 8gb memory. (Samsungs USB-C to USB-A works fine for this if you happen to have one)
Or a USB hub.
Then extract your downloaded firmware zip, just cut and paste "sd_update" folder to external memory stick and start phone in dload mode.
There are instructions that come with the firmware on how you flash it (dload mode, folder structure etc.)
External memory is needed as Mate 10 Pro can't read internal while in recovery.

Yes, just downgrade, get the unlock code and then unlock. It doesn't matter that you tried to get the code while on B145.
