[Q] Backup, Unlock, Root, Custom Rom?

THE FOLLOWING STEPS ARE NOT MEANT TO BE A "TUTORIAL", IT´S JUST TO DOCUMENT MY STEPS TO GET AN CUSTOM ROM!

Ahoi Matrosen! (German for Hello )
I´ve decided to unlock the full power of my lovely Ascend P6. But i want to make it the "right" way.
My Plan so far:
1) Make a full Backup (in case i have to use my warranty, i like to fully reset my Phone to its original status)
2) Unlock
3) Root
4) Install CWM
5) Install custom Rom
---
What I´ve found by myself:
1) Nothing...? Any Hints/Tips/Help?
2) I´ve found these german description:

3) I´ll use on of these:

4) I like to try this:

But i´ve Firmware B125...don´t want to brick my phone with CN-Firmwares . Any Hints/Tips/Help?
5) This one sounds good:

So, what do you think? Is this the "right" way? Any Ideas? Help?
Thanks in forward!

When you want to install Hyd52rom for KK you don't need to go over the Chinese firmware just flash the KK beta. And I don't know if the unlock code helps.

1) Full backup is not possible. What you can do is to have a backup via TWRP or CWM. After flashing your backup, you can reflash the stock recovery via fastboot to make the changes seamless.
2) That's really interesting. Never have seen this method before to unlock the bootloader. If it works, you have found a new way to unlock the bootloader for our Huawei P6 community! That would be awesome! Otherwise, you will have to go through the risk of bricking by flashing B118cn or B120cn. Or you can try installing Kitkat beta since I heard that it also works, and it is much less risky. I would probably install the kitkat beta if the method you showed didn't work.
3) Well that works. But if you are on kitkat you will need a different root method such as flashing superuser.zip.
4) TWRP is better than CWM imho. I used to like CWM the best, but TWRP was easier to use and had more features such as charging battery, having access to terminal, backups, restores, installing zips and wiping certain partitions. CWM on the other hand in my experience can only install zips, do backups and restores, and do a factory reset (format /data only). So I highly recommend TWRP over CWM. And the link you posted of TWRP is for kitkat.
This is what you can try with least risk of bricking:
i)You can update to kitkat directly with unlocked bootloader.
ii) Do what I have on my post here: http://forum.xda-developers.com/showpost.php?p=49986799&postcount=10
and you will have TWRP easily installed.
5) I can't help you with this one, never tried it. TBH I am skeptical that a ROM can be that good especially with hardware as a limitation to certain features. But by all means go ahead and try it if you want to.

Thanks so far!
Does the order i´ve suggested make sense?
Unlock > Root > TWRP?
I think we need a compact tutorial. Any Volunteers?

I don't know, but I think this one here is quite good, if you are looking for one.
http://forum.xda-developers.com/showthread.php?t=2566453
It lacks a order of how you should get to a custom rom, but everything from instructions to unlock, root, disassembly, themes are all there.

Base: B125
Okay...what i´ve done so far:
1) Unlock the Bootloader (success!)
Used this Method:
Unlock Bootloader - Fastboot Method
Things learned:
a) The easiest way to enter fastboot is by "adb reboot-bootloader" via cmd
b) hisuite Driver works fine
c) There is no "Fastboot"-Option on the P&, don´t look for it
d) The article above states it will do automatically a factory reset, in my case, it didn´t! So i can still make a full Backup after next step...
2) Installed TWRP (success!)
Used this Method:
Permanent Recovery TWRP 2.6.3.3
3) Doing full Backup on my SD-Card with TWRP
Currently waiting
Next step planned: Install custom Rom.
No guarantee this works for everyone, but i´m happy right now . I´ll update this Thread.

Well I guess this is good news. The bootloader unlock no longer requires going to B118cn or B120cn! Now just via terminal

Backup completed.
4) Rooting Device via TWRP (System reboot) and Play Store Method (success!)
So, time to sum up:
Unlock B125, intall TWRP, make Backup, Root. SUCCESS!
Next Steps/Questions:
Install custom Rom: Which one is the most "stable"?
Install custem Rom: Do i have to install Stock Kitkat Beta to install Kitkat Custom Rom? Or can i just install custom Kitkat Mod right away?
TWRP: After update to Kitkat...do i HAVE to update TWRP (special version for Kitkat)?
Thanks!

Worked for me too. And before when i check if my bootloader is open there stands it was open, I tried to flash something that doesn't work.
Than I used the command and than i was able to flash TWRP.
And also he didn't make a factory reset.

I think it is best for you to install stock kitkat beta to install kitkat based roms, even though some people haven't run into issues without doing so.
And yes, I would recommend you to update TWRP to special version for kitkat, but yet again, some people haven't experienced issues while some have.

Okay, currently downloading Kitkat Beta (using Mirror from huaweiblog.de; sorry, can´t post outside links; not sure if it is the same like here). Let´s see where this story ends
OT: Any way i can get rid of these google captchas?

Hi. I guess I read all the postings from this thread. So I have still one question left. Did you check if your b125 bootloader was locked or unlocked before you started?

Yes I checked it was unlocked but I can't flash anything, after I ran the command I was able to flash TWRP.

For me he said it was locked from the beginning.
Problem right now: Can´t use Kitkat Beta Update.app viá dload method...alwas TWRP starting .
Any Ideas?

Install stock recovery before flashing KK. There are several descriptions how you can do that.

5) Revert to Stock Recovery to update to Kitkat Beta (success!)
Using this method:
Revert to stock recovery ( B118 )
6) Installing Kitkat Beta viá UPDATE.APP/dload-Method (success!)
Now on 4.4 . Kept every APP/Setting as far as i can see.
7) Installing TWRP for Kitkat (success!)
Using this: TWRP Recovery 2.6.3.7 | ONLY For Android KitKat
Sigh...long way to go

I followed your steps and flashed TWRP, but now I can't get into the recovery. How do you do it?
My P6 just keeps showing the Huawei Ascend logo...

So u didn´t intall TWRP?
Usally, if your P6 stucks on Huawei Ascend Logo you are in Fastboot Mode. Excuse my bad english, but i don´t really get your Problem.
What was your last step, what are you planning to do?

8) Installing Custom Rom (success!)
Using this: LightningKat RC02.1
Looks good so far, still testing...

Sorry, it's a little bit late
I managed to install TWRP and rebooted.
But now I can't boot into TWRP. If I send "adb reboot recovery" or press VOL- and Power when the phone is off the device starts and gets stuck at the Huawei Ascend Logo

Please disconnect your Phone from USB (in case you are still connected) and just power off the phone. Wait a few seconds and just restart. For me this one worked.
After this power off again and try VOL + and - and Power to get into TWRP. Does it work?

Root H815 on MM 6.0 V20d?

Hi guys ☺,
I bought today G4 eu model,it came with Marshmallow 6.0 V20d version.
I want to root it because of Greenify and Xposed,to increase the battery time,maybe later to flash some rom but...
There is a lot of topics on this subject,I started to read but I'm lost right now...as far as I saw,I can't root Marshmallow without unlocking the bootloader,only Lollipop,right?
Is it a big trouble to go back from MM to LP?
I'm not new in this flashing and rooting stuff,I had (still have) a Motorola Razr XT910,I flashed it 100 times for sure for 3.5 years but I didn't had to unlock the bootloader (it's impossible anyway) and there's a custom recovery Safestrap,modified Twrp which allows to flash and use 6 different roms,from JB to MM,without changing the kernel...
I will be grateful if someone can point me in the right direction,to give me some useful links etc.
And is there some list which procesess are safe to freeze with TB and which ones I can greenify?
Oh,and the bloatware too...
Sorry if I'm demanding but I want to bring out the best from this phone
Thank you in advance

Hi,
root without unlocking bootloader works only on lollipop, right. Not sure if u can downgrade, but when, u will use "LGUP" tool with the "H81510D.kdz" file. Maybe there exists a pre-rooted kdz to flash.
If u want to root android 6, u need a unlocked bootloader. Rooted Android 5.1.1 or unlock bootloader with rooted android 6.x.x

Ok,I successfully unlocked the bootloader but now I'm stuck with rooting and installing Twrp...
I've downloaded BETA-SuperSU-v2.67-20160121175247 and TWRP-3.0.0.0-H815+ but there's a lot of metods,which one should I use?
Flash SuperSu+Twrp with stock recovery?
Install Twrp with adb command and then flash SuperSu with Twrp?
Install both with adb command?
I also saw somewhere that I must flash some other kernel that is already rooted...
I just need root and the Xposed for now,help me guys!

Im also Confused..Where can i find rooted kernel?
I already did this Method u said...But I got Boot Loop
Then I revover my phone with Lg Bridge
We need to find this.....I also Had Android MM with V20d

In my case I wasn't able to flash recovery on the stock kernel, I had to flash boot.img unpacked from the custom kernel like SimpleGX and only then I was able to flash recovery and full kernel through it.

the method i followed was-
1. boot into twrp recovery with adb command(you need to have the twrp.img file in PC and also copy it in internal memory of your phone with SU)
2. flash systemless root with twrp
3. reboot
4. install flashify
5.flash twrp.img from your phone.
6. done
but there aren't as much benefits of rooting as any other phone. viper4android doesn't work. spirit fm doesn't work. xposed doesn't work properly.(these 3 were the main reasons for which i rooted)

I didn't know i could flash something other than .zip files with twrp.
As for viper4android i tried normal way, flashed it with twrp, flashed extreme music mod with v4a fix. None seem to work. The drivers never get installed.
Xposed i haven't tried. I was in process of getting more information about it by reading various threads. But all seem to point to problems like bootloop, fc and Bluetooth issues. Can you guide me towards the best version of xposed for v20d with way to avoid problems or with as less problems as possible?

I think doesn't need to install recovery to root the phone.
Just this:
1) adb reboot bootloader
2) fastboot boot TWRP-2-8.7.0-h815.img
Wait a second and it will open, on the phone, the recovery.
Once open go to Advanced -> ADB sideload and take a swipe to start it where it says "Swipe to Start sideload".
Now on the PC write
3) adb sideload BETA-SuperSU-v2.67-20160121175247.zip
( If it says after the instalation to install supersu etc just abort it)
And then, when installation is complete, press "Reboot System"
I rooted it this way, without install TWRP Recovery

Yeah - but the question has to be asked - why unlock the bootloader and root and not install TWRP? If you've got as far as unlocking the bootloader you might as well make life easier for yourself and install TWRP - that way anything you want to flash in the future can be done without being tethered to the PC, and also allows you to take proper full system image backups etc.

Of course , i agree with you. By the way, we can't root g4 on m6 without unlocked bootloader.
And finally, i decided to pass twrp on my phone, for every file i want to install from twrp, and not every time to boot from pc
You're right
p.s. the first thing i did after twrp installed, was to install g5 live wallpapers

Not getting automatic updates after root,unlocking bootloader, new framework

I rooted my phone 2 month back, but even after root i got some of the system updates. But in order to play pokemon go and to use xpose modules i unlocked bootloader and installed a framework.
Now i am not able to get the system updates, which i usually get in a month from asus.
Kindly help me how to get the latest updates and install them safely to my phone.

You didn't say which of the many versions of the Zenfone 2 you own, so I'll assume ZE551ML and go from there. It sounds like you used the official bootloader unlocker. The disclaimer states:
"... the software of Revised Product will no longer be deemed the software of the Original Product and can no longer receive ASUS software updates..."

You now have to manually update. As well, you should unroot and return the system to the way it was before (uninstall busybox, re-enable bloat, remove xposed framework, stock recovery, etc). And depending on whether you've also changed to a custom recovery you will either need to follow these instructions:
a) No custom recovery
b) TWRP custom recovery
PS. You also didn't need to unlock the bootloader to install xposed.
PPS. All this information is readily available through a simple google search. Terms I used were:
1) "flash ota zenfone 2 rooted"
2) "zenfone 2 bootloader unlock"
3) "xposed zenfone 2 instructions"

Yes my phone is ze551ml,
I hv custom rom twrp.
Can u suggest a detailed explanation or any link with same problem.
I am a beginner and afraid of getting my phone bricked.

6) Now i wanted to UNROOT the device and back to stock so that i can get OTA Oxygen 4 and 4.0.1.
7) i followed steps below,
a) downloaded oxygen 3.2.1 and stock recovery.img
a) fastbootloader, and connect device.
b) fastboot devices
c) fastboot fastboot flash recovery recovery.img
d) fastboot oem lock - when i used this command and accept YES, screen got black and no further instruction for ADBsideload.
8) i used to restart the device in recovery but black screen, fastboot loader working.
FASTBOOT MODE
PRODUCT NAME - ....
VARIANT - MTP UFS
BOOTLOADER VERSION -
BASEBAND VERSION -
SERIAL NUMBER - .....
SECURE BOOT - enabled
DEVICE STATE - locked
9) and if i start the device in normal it asked for screen pattern lock but my existing unlock pattern doesnt work.
10) by using all the chance for screen pattern unlock it showed DECRYPTION UNSUCCESSFULL, clicked on RESET PHONE but again screen black in recovery mode.
11) NOW if i start my device it again shows DECRYPTION UNSUCCESSFULL and asking for RESET PHONE......
What to do now.....

Device is back to stock, this method is used by One plus asstance for unbrick hard bricked device by remote control your PC. Then device is back to completly stock. No root no custom recovery etc. You Can now use OTA for update or using adb sideload or manually flash the entire ROM from sdcard. Thank you for appreciate :good:

just wanted to highlight the things you did that caused the issue
1- flashing the stock rom through twrp, it's possible specially with the latest TWR0-11 but not advisable, you better always flash stock recovery and then sideload rom (full rom not update) and then fast boot TWRP back and reflash root... any other method always causes issues...
2- the 30mg updates do not work on a rooted device
3- unrooting without immediately sideloading rom will always cause the black screen and loop to recovery, it's not required to unroot unless you want to go back to full stock experience...
4- this the biggest problem you made, you relocked the devices bootloader, you also did it while the device has a lot of issues (some mentioned above) so the device bricked instantly, if you are planning on unlocking the device again ...NEVER NEVER relock the device again , there's no need to do that , all you need to do to go back to a full stock experience is to wipe everything in TWRP , flash stock recovery then wipe everything again from there, then sideload full rom (latest stable version) , then for good majors in the new rom recovery wipe everything agian and boot to system and from system do a factory reset. then recharge your device to 100% and re encrypt it if it's not...after that you're 100% on a full stock exerience and will receive ota and it'll work... and at that state only (without root or TWRP) you can relock the bootloader (which is gain not necessary at all, there's no benefit to it)

How to successfully update from Android 9 with TWRP, Root (magisk) to Android 10?

Hello!
so I read all the threads regarding android 10 and mi a2 lite but i didn't find a proper solution or guide for the following problem:
I am on Stock Android 9 with unlocked bootloader, TWRP and Magisk Root.
Now i want to update to the v.11.0.4.0 Android 10 Update, but i want to keep root working!
Is there a way to do this?
If yes, please tell me how (i'm not a pro in flashing, so please explain in detail )
EDIT: i dont mind if i loose TWRP, i just want to keep root and android 10 working
thanks in advance!
stay safe and stay home
Alex

Yes. It's complex because of TWRP.
https://forum.xda-developers.com/mi-a2-lite/how-to/10-0-4-0-to-10-0-7-0-ota-keeping-magisk-t3916863

Thanks for the answer, i already saw this thread but as I already said I'm not a big Expert in this topic, so that guide in the thread is too complex and short for me (and for other most likely too...)
Maybe you can explain it more precisly to us?
I would be very greatful for this!
Or if you know a way too archieve what i want but loose twrp and data... I wouldn't mind. I dont Need twrp and my Phone is New... So
Thanks in advance!
Best Regards
Alex

You can't do it simpler. Mostly because you've got to get back to stock for the OTA.
You can do it different. Get the fastboot. Flash that (don't erase userdata). Then install Magisk and TWRP again.
Not every release gets a fastboot but 11.0.4.0 did so you have this option.

Can you explain this more for me pls?
- What exact files do I need?
- what exactly should i do with these files? (flash with terminal, TWRP, Slot A, Slot B, etc.....)
- is it relevant which version of Android 9 i have?
you would help me alot, if you explain it in detail so that i can do it.
I already tried in android 10 unlocking bootloader and flashed the "disable force encryption" but got stuck on booting screen.
Pls tell me how exactly i should do what, and i will post my results
Thanks !
Best Regards,
Alex

Recomendations
Hello,
I just updated from Android 9 stock ROM, to Android 10 with a custom ROM.
I followed this two YouTube guides from the same user:
How to root and install TWRP:
https://www.youtube.com/watch?v=wy9Z_NN_7Tg&list=LLm7cWm_1QXORlLa5XeTETUw&index=12&t=365s
How to install custom ROM(In my case I installed Evolution X with Android 10 following these steps):
https://www.youtube.com/watch?v=S0pcmA_ew-Y&list=LLm7cWm_1QXORlLa5XeTETUw&index=13&t=173s
**Advise**
- Use the same files and versions that he uses, If you use/do something different, you are going to have some problems.
What I'm currently running on my Mi A2 Lite:
- Evolution X ROM(Android 10) -> https://forum.xda-developers.com/mi-a2-lite/development/rom-evolution-x-3-3-t4014685
- Nitrogen Kernel r3 -> https://forum.xda-developers.com/mi-a2-lite/development/r1-nitrogen-kernel-mi-a2-lite-t4011019
Everything has been very stable at the moment(1 week and lots of gaming and restarts and tests), so I feel fine sharing this.
Best,
delokt

Install instructions in that thread. TL;DR Run the flash_all_keeping_userdata script to upgrade to the version you downloaded. 11.0.4.0 is what you want.
You have Magisk and TWRP. Install them the same way you did before. Go read their threads if you forgot or use the last part of my guide.

Hello Friends, i have good news, i successfully updated my Phone to android 10 and keep TWRP and magisk!
I did the following steps:
- clean install of fastbood v.11.0.4. Android 10 via Mi-Flashtool
- powershell adb: fastboot boot twrp-3.3.1-dees_troy-daisy.img
- TWRP should open on Mi a2 lite. go to advanced and activate adb sideload
- powershell: adb sideload twrp-installer-3.3.1-dees_troy-daisy.zip
TWRP should now be installed.
Then i tried a reboot system and got into the welcome screen, so it booted.
What i did next is, the magisk v20.4 zip file move to sd card or internal storage of the device and flash it trough TWRP.
DONE!
now your phone should reboot to system. It now has Android 10 and magisk installed and working!
Hope i can help someone else with this.
