Does this work with the GRA-UL10 variant? (64GB) I am already running Marshmallow on build number GRA-UL10C185B320.
[Huawei P8 Guides, News, & Discussion] Rashad83:
Yes it should work!, the UL10 is the UL00 but with more memory capacity and dual active 4g sim capability instead of one.
[Huawei P8 Guides, News, & Discussion] maikeru-chan:
Will try it out once Huawei's unlock service is up. :good: It is currently down.
[Huawei P8 Guides, News, & Discussion] belal elsayed:
Thankes :highfive:	it works with me ( Huawei P8 gra-ul00 ) , you are awesome :victory: :cool:
[Huawei P8 Guides, News, & Discussion] maikeru-chan:
This guide is very well detailed and is easy to follow. It works, thanks! I also wanted to ask if it is safe to install busybox in the system?
[Huawei P8 Guides, News, & Discussion] Rashad83:
Yes it's safe.

hi and thank you for good works,

I can OTA update wihtout unroot my P8 ?(for futur update)
[Huawei P8 Guides, News, & Discussion] Rashad83:
Ty, if i understand you correctly you mean if you root and install Twrp on your device will it be able to take OTA updates.

The answer to that is no, you will be notified of an update but you will not be able to apply it because on Marshmallow you need to have the stock recovery and the system directory unmodified for it to apply updates. So you will have to restore the stock recovery and remove any changes you made to system directory if possible, and a good measure to take afterwards is to remove root(i don't think it's necessary since it's systemless) and reset the device before applying any updates. After that you have to root again if you want it back.
[Huawei P8 Guides, News, & Discussion] deraiz12:
Thank for your fast answer, you have a link for stock recovery marshmallow (I not found on google)
[Huawei P8 Guides, News, & Discussion] Rashad83:
No, you see it depends on what rom you have before you root the device. So what you do is download the rom you currently have installed on your device from Huawei download page and extract from it the stock recovery using HuaweiUpdateExtractor.
[Huawei P8 Guides, News, & Discussion] Rashad83:
Farewell everyone it has been a lovely journey, I really loved this phone i only wished it had dual front speakers and a better earpiece add to that a better developer support but other than that this was one of the best phones i ever owned. But i guess it's time to move on i just sold this phone since my main device is a Nexus 6p i barely have been using the P8 . I would like to wish everyone the best of luck and see you around in the other Forums.
[Huawei P8 Guides, News, & Discussion] NoSkypeOnCM:
when I use

adbreboot-bootloader

and get to fastboot mode, the P8 is not detected by the Windows OS (not even trying to install any driver)

does anyone know this issue?
[Huawei P8 Guides, News, & Discussion] pkdd_:
Will this work on my Huwaei P8 Model #: GRA-L09 and build #: GRA-L09C368B184?
[Huawei P8 Guides, News, & Discussion] majaczos:
Which one? B370? No, it will not work.
[Huawei P8 Guides, News, & Discussion] :
Will I be able to recover previous state of phone after installing those modifications? I'm thinking about rooting it, but I may need my warranty one day :D

Sent from Huawei P8
[Huawei P8 Guides, News, & Discussion] Rashad83:
To use adb commands you need the phone turned on and working normally not in the fastboot mode also you need the developer mode in your device activated in the settings menu, please follow the link in the first page for installing the necessary drivers. If the device is in the fastboot mode then you can use fastboot commands that start with the word fastboot. For exp: fastboot reboot.
[Huawei P8 Guides, News, & Discussion] Rashad83:
Yes it should work fine but no promises, please make sure you have a backup of your stock recovery in case things go south.
[Huawei P8 Guides, News, & Discussion] Rashad83:
The moment you unlock the bootloader is the moment you lose warranty unless the service center you go to overlooks it. I am saying this because if you decide to lock it back it will state "relocked" instead of the default state "locked". Now there are software tools that promise to return it back to the locked state but i haven't tested them so i can't vouch for that claim.
[Huawei P8 Guides, News, & Discussion] Rashad83:
On B370 it works fineI i haven't tested it my self but others have reported that it is working. As long as the new updates are still Marshmallow updates then the root method described should work with the outdated twrp zip. I think there will be a need for a new Twrp flashing zip only when the P8 gets Android Nougat 7, if that ever happens.
[Huawei P8 Guides, News, & Discussion] majaczos:
I never said that B370 doesn't work. It works. I was talking about the installation - 'pkdd_' has B184 branded software and it's highly recommended to install B37 (and B321) on the stock-non branded version. 'pkdd_' shopuld make a clean debranding of his/her device and install B370 afterwards.
[Huawei P8 Guides, News, & Discussion] DonBongJohn:
nevermind
[Huawei P8 Guides, News, & Discussion] Topigo:
I have the same problem. I have B370 and when I in bootloader, computer not detect phone and fastboot command said waiting for device.

Edit:

USB3 is problem. With USB2 is working.
[Huawei P8 Guides, News, & Discussion] NoSkypeOnCM:
Oh dear, really?

I don't have USB 2 on my computer at all. But thanks for sharing, I will try that.

[Huawei P8 Guides, News, & Discussion] bednim:
Thanks a lot for this guide. Worked flawlessly on my partners p8 - marshmallow Ota update then followed this tutorial. No bootloops, no hangs. Root and twrp works perfectly.

I also got rid of few apps that sat in her phone unused.

Would be nice to have bigger list of what can be safely removed. I have also removed all Google apps and reinstalled just the one that she was using like chrome and hangouts.

Thanks a lot again!
[Huawei P8 Guides, News, & Discussion] NoSkypeOnCM:
I was now able to unlock the bootloader (via USB 3 port - i dont know, why it did not work before).

However, if I flash TWRP, the boot to recovery gets stuck at the huawei logo.

I tried official 2.8.7.1 and the modified version that is provided in this thread.

The normal boot works, no bootloop.

I wrote a guide today how to root huawei p8 stock firmware b370 - because if you would root p8 with the latest SuperSU 2.76 the phone cannot boot to system....

What's the problem, this twrp can used with Marshmallow even with the newest firmware: http://xdaforums.com/showpost.php?p=65499548&postcount=564
[Huawei P8 Guides, News, & Discussion] Tecalote:
Use only the modified TWRP - it works well with the newest firmware too. (the official one is not marshmallow compatible) In the moment you flashed TWRP (finished) with ADB you have to disconnect the USB cable from PC and Phone. Then you must immediately reboot with the Hardware-Keys to TWRP (not with ADB, and not into system) Press the volume up Button and the Power Button until the phone restart. In the Moment you see the Huawei Logo skip holding the power button but not the Vol Up Button -This one press until TWRP starts (needs a while) So, TWRP is successful installed. If you don't do this steps, the flashed TWRP will overwritten by Stock Recovery
[Huawei P8 Guides, News, & Discussion] NoSkypeOnCM:
I was holding the Vol + for 6 minutes after flashing (in fastboot, not adb - I think that was a typo?)

It is still stuck at huawei logo
[Huawei P8 Guides, News, & Discussion] Tecalote:
I would flash this TWRP once again: http://xdaforums.com/showpost.php?p=65499548&postcount=564 As soon you see, the new_twrp is succesful flashed, disconnect des USB cable from PC and Phone - dont use fastboot reboot. Then press first the Vol+ and second the Power Button as long the display is black and the battery is humming and you see the Huawei-Logo. In that moment skip holding the Power Button but all the time hold the Vol+ Button until the Phone reboot to the TWRP. This should work, because it works always! It works only not, if the TWRP is not succesful flashed, or you have a rebbot to system between, or you make something not correct skip holding and holding the Buttons. By the way - which firmware you use (Stock or custom, which number)
[Huawei P8 Guides, News, & Discussion] NoSkypeOnCM:
I think I do exactly what you say - I just tried again with the same result - I don't think it takes 5+ minutes to first-boot twrp?!

I use the latest OTA update I got - and I just noticed, that its not Marshmallow but Android 5.1.1, EMUI 3.1 BUILD GRA-L09C02B194 - Providers are great xD

Anyway, both tWRP (the New_ from this threat as well as the one from twrp.me have the same effect.

It seems, this is vodafone brand firmware. Maybe this is the problem. I would FIRST backup all my data with Huawei Backup Tool and second with TitaniumBackup. Next, I would download a full firmware, wich is not branded. I have actually b370! I would take this one: http://xdaforums.com/huawei-p8/how-to/emui4-0-1-p8-official-marshmallow-6-0-t3417212 Download the first link, extract it - you get two files (update.app and Meta-Inf), copy both to a new folder called dload to your external SD. On PC use the Huawei Update Extractor: http://xdaforums.com/attachment.php?attachmentid=3262545 Install this on your PC, after navigate with this program to update.app and ectract two files from it: recovery.img and boot.img (not recovery2, not anything else) With Minimal ADB and Fastboot flash this two files to your Phone (adb reboot bootloader / fastboot flash recovery recover.img ...and... fastboot flash boot boot.img ) After disconect the USB cable und press Vol+ and Vol- and Power Button - the phone should make after a Force Upgrade to b370 without branding. (The update.app must be before doing that on the external SD in the folder: dload (together with Meta-Inf). If the Upgrade is succesful, phone reboots - mostly with factory reset, but sometimes not. Later you can flash TWRP and Root it with one of the following methods: http://xdaforums.com/huawei-p8/how-to/rooting-huawei-p8-marshmallow-emui4-0-1-t3431249/post68010525#post68010525 But be careful in all you doing. If you make something wrong, Phone dont start again.
[Huawei P8 Guides, News, & Discussion] NoSkypeOnCM:
Hmm, I can always go back to fastboot and re-flash everything to stock state, can't I?

A Backup would be useless if it cannot be restored anyways.

Interesting, How do you know it is a VF brand ?

I didn't know that branding makes a difference in terms of a recovery ?!

thank you :)
[Huawei P8 Guides, News, & Discussion] Tecalote:
Yes it seems this branding let you not boot to Twrp. Same thing I heard from a German User. In the moment you have already TWRP installed, but you cannot boot into. You cannot go back to stock state, before reflashing the stock recovery. If you find a download for your actual full Vodafone firmware, you can extract the recovery.img and flash this one. In that case you don't need the boot.img because it is not modified. After you have the original stock recovery flashed you could download the Firmware I told you. Backup all your apps and data is recommended. After you can make a Force Upgrade to the new firmware I told you. If it is successful you will have no problem to flash and boot TWRP and do what you want... Before upgrading be sure you are not rooted with KingRoot or simular methods. Stock Firmware must be unrooted and have the Stock Recovery otherwise a firmware upgrade will fail

Have a nice day
[Huawei P8 Guides, News, & Discussion] NoSkypeOnCM:
I thought the branded stock ROM overwrites the recovery with the branded-stock recovery?

I found the old B120 (Android 5.0) branded ROM. I understand the dload update - but just in case, how can I re-flash the branded B120 later on (downgrade)?

Do I really need an external SD card? I would actually have to buy one if there is no other option.

Titanium backup tells me, that it wont work without root ?!

EDIT: I flashed the recovery of VF_b120. Booting to recovery still does not work (still stuck at Huawei screen).
[Huawei P8 Guides, News, & Discussion] Tecalote:
Use the Huawei Backup Tool (its always integrated in every Huawei Rom) don't know how is the name in your language (in German called Datensicherung) to backup all your apps and data, sms, calendar. For WhatsApp use the inbuilt Backup Tool. You cannot flash Stock Rom if you have TWRP installed. You must first reflash the stock recovery! You cannot boot to TWRP does not mean, it is not installed. With installed twrp every stock update will fail! Read my posts before more times. I have everything written. If you don't believe I cannot help you. Why you want revert to the same branded stock Rom you allready have? If you don't want marshmallow you can use unbranded b200. It is lollipop Rom. If you want to have TWRP I think you have to say goodbye to your branded version. It seems really it has some inbuilt blocker so people cannot use Custom Recovery and Root. May not in every VF Rom. Otherwise I cannot realize why you could not boot into the flashed custom Recovery...
[Huawei P8 Guides, News, & Discussion] NoSkypeOnCM:
well, first of all the VF ROM ist b120, not b132 - I had that wrong in my post. I fixed it, but your reply was faster.

As edited in the previous post, I flashed the recovery of VF_b120. Booting to recovery (the vf stock one now, of course) still does not work (still stuck at Huawei screen) for both methods (Vol+ and Power as well adb reboot recovery).

booting to "update mode" (Vol+, Vol- and power) does not seem to work either - stuck at huawei logo as well.

I don't know which changes were made and which problems were introduces with the new version. So I like the option to return to the original state, that's why I ask.
[Huawei P8 Guides, News, & Discussion] Tecalote:
Okay I understand. In that case I have no more ideas but one is for sure, if an update dont work, there are no changes made. So everything is as before. Is it possible you tried to flash TWRP before you unlocked your Bootloader? I really don't know, what's happened with your phone, why you cannot boot to any Recovery or make a Force Upgrade... Sorry I have to pass and I think there is no help that way.

---------- Post added at 06:52 PM ---------- Previous post was at 06:32 PM ----------

@NoSkypeOnCM ...and the newer firmware is a full version? Not a update.zip? You have got the update.app right? You can try it with local Update from the settings. Another way is trying with HiSuite
[Huawei P8 Guides, News, & Discussion] jazzl:
Dear All,

I hope someone can help me to get further with this. After hours, I managed to get the unlock code from Huaweis website. For those who may have trouble with this, there´s one thing that´s not yet been mentioned:

If only the Chinese unlock website works (my case), you should leave the first dropdown menu where it is: This means mobile phone, where the others are tablet and something else I don´t remember.

Also, what is crucial is that you on the first line as model enter HUAWEI GRA-L09. GRA-L09 alone won´t work!

Anyway, in (elevated!) adb I can see the phone with adb devices, but when I use adb reboot bootloader and get to reboot with the screen where it says "Phone unlocked", all commands will return "waiting for device".

I have Hisuite installed, which includes the drivers of the phone, and all operations are fine in normal phone mode.

Any ideas what´s wrong?

Thanks
[Huawei P8 Guides, News, & Discussion] Tecalote:
If you are on the Screen "Phone unlocked" you have to use: fastboot devices ... fastboot flash recovery new_twrp.img ... All commands there beginning with "fastboot" HiSuite must be closed in the background
[Huawei P8 Guides, News, & Discussion] jazzl:
Thank you, but fastboot devices does not show anything, it just returns to the prompt. Using fastboot for unlocking or for setting up TWRP returns "waiting for device". I tried with Hisuite shut down, but same result.
[Huawei P8 Guides, News, & Discussion] Tecalote:
It seems as an driver issue. Look in Device Manager (showing hidden devices) on PC if the ADB Adapter is correctly installed. The p8 must be connected for check this.

I wrote a Thread http://xdaforums.com/huawei-p8/how-to/rooting-huawei-p8-marshmallow-emui4-0-1-t3431249

Maybe you find there something helpful.

Which firmware do you have?
[Huawei P8 Guides, News, & Discussion] jazzl:
I have Huawei HDB Interface and Android Adapter ADB interface in Control panel. Firmware is 4.0.1, same as the thread you´re linking to. Didn´t see anything there about the "waiting for device" issue though..

Thanks

---------- Post added at 06:01 PM ---------- Previous post was at 05:08 PM ----------

I made it! I deleted all drivers for the Huawei in dev manager, asked win to find em again AFTER terminating some service running for the hisuite. So it was not enough to simply close the hisuite itself.
[Huawei P8 Guides, News, & Discussion] Tecalote:
USB Debugging must also activated in Developer Options and in Security must be activated "unknown sources" - it should work. If not, try it on another PC
[Huawei P8 Guides, News, & Discussion] jazzl:
Thanks, now I got a new issue. Having succesfully flashed TWRP, everything works as it should - except for being able to boot into TWRP.

I´m turning off the phone, then hold down power and volume up, but only get Huaweis erecovery tool.

Any ideas?

Thanks
[Huawei P8 Guides, News, & Discussion] Tecalote:
Of course, this is normally because you forget disconnect the USB cable from PC or Phone. Now you have flash TWRP again, before reboot into recovery disconnect the USB cable
[Huawei P8 Guides, News, & Discussion] jazzl:
Thanks, what a shame I did not know that as I was succesful in flashing again - with cable connected.

I searched for my problem on google, and nowhere is mentioned that about the cable as a solution, so a wellkept secret - lucky me I ran into you :)

Now I have the same problem again with fastboot not seeing my device. The only condition that´s different from before is that I now am 100 % charged and before was at 83 %.

It would be opposite logic if this is the trigger, but nevertheless I will try to do it again when there´s less power on the phone.
[Huawei P8 Guides, News, & Discussion] Tecalote:
I hope you will be able to flash TWRP again and successful boot to it. Another information: Your Android Version is 4.0.1 - not your firmware. Your firmware must be with this Android Version b370. If you want to get Root permissions, you better read my Thread I gave you the link. B370 cannot be rootet with SuperSU 2.76 - it cannot be started again, if you do this. Following my guide will solve this next issue.
[Huawei P8 Guides, News, & Discussion] jazzl:
Thanks, I read that part indeed. I´m planning to user SuperSU 2.46.
[Huawei P8 Guides, News, & Discussion] jazzl:
Ok, I brought my phone down to 81 % charged, and again I was succesful working in fastboot mode - odd! :)

So I flashed the TWRP, unplugged the cable, and tried to get booted in TWRP by holding volume up and the power button after turning off the the phone.

But.. the only thing that happens now if I do this, is that the phone keeps rebooting, showing me the Huawei logo. That´s until I release the buttons, then the phone boots as normal.

Any ideas what´s going on?

Thanks
[Huawei P8 Guides, News, & Discussion] Tecalote:
I have also GRA-L09 and never had this problem. If this occurs, something was not right with holding the buttons. It's difficult the first time. In fact if the phone boot normally to system, the Stock Recovery rewrite TWRP. It is necessary to boot first time immediately after flashing TWRP to Twrp. You must flash it ones more. After that disconnect the USB cable. Hold first the Vol+ (be sure it is + and not -) and stay there. With the other finger hold now the Power Button only until the Huawei Logo appears. Always stay on Vol+ but skip holding the Power Button in the moment the Huawei Logo appears! Staying and waiting with one finger on the Vol+ Button until the Logo of TWRP appears. This could be need one minute! In the moment you can skip holding also the Vol+ Button.

First successful boot to Twrp means, the Stock Recovery cannot reflash TWRP anymore. If TWRP ask you for the Rights to modify the system swype to confirm this. Don't say "mount system partition read only"! It's not right to do this!

It is also necessary to use the right TWRP. Don't take any from the official TWRP Site, it doesn't work with 4.0.1.

Take the compiled one, called new_twrp!
[Huawei P8 Guides, News, & Discussion] jazzl:
So this will not work with twrp-2.8.7.1-p8.img? That´s the one most guides mentioned.

So you´re saying that just once having a succesful complete system boot, as opposed to TWRP - even without the USB cable - I´ll have to flash again with TWRP?

In that case, it´s weird that I don´t get at least the erecovery anymore.
[Huawei P8 Guides, News, & Discussion] Tecalote:
No, twrp-2.8.7.1-p8.img don't work with firmware b321a and firmware b370, Android 4.0.1. You must flash: http://xdaforums.com/attachment.php?attachmentid=3832899&d=1470302851

The Rom has 2 Recovery: The Stock Recovery and the E-Recovery. TWRP comes to the place instead the stock recovery and the E-Recovery is untouched. With USB cable connected you will always arrive E-Recovery.

If you would like to have TWRP for Rooting and Nandroid Backups it must be flashed to the place of the Stock Recovery. Immediately after flashing TWRP it is the rule to boot into TWRP Recovery. Otherwise the Rom rewrite the Stock Recovery 1, and you don't have TWRP.

If you like to update to the next firmware you have to unroot your phone and flash back the original boot.img of Stock. That's why it is recommended to take a complete Nandroid Backup after successful boot first time to Twrp. Store it on your external SD. Twrp "select storage" so you have all you need even for firmware update issues. I cannot teach you all the basics you have to know.
[Huawei P8 Guides, News, & Discussion] jazzl:
Wow, what a mouthful! Now I finally managed! I tried first with the SuperSU version I mentioned, 2.46. This did NOT work, but following your advice with v 2.66 had me getting there. Thanks God that the first thing I did in TWRP was backing up everything on my system, or I´d have needed to work hard getting my phone up and running again when I tried with SuperSU 2.46, that made my phone stuck at the Huawei logo after reboot.

Many many thanks!
