Since I was kind of not happy with the official Android 6.0 (B550) as it did have (again!) the so called "double-tap-keyboard" bug I've decided to make a rollback to B190 (as it does not have this bug - details about the bug here -> http://xdaforums.com/p8lite/general/double-tap-problem-keyboards-firmware-t3343287). Procedure to follow is the same I did with BETA so if you follow the below short guide you should get back (if you want) quite safely to Lollipop.

Please carefully follow the instructions. If you do not understand or are not sure what to do - DO NOT DO ANYTHING - just don't make downgrade.

It applies for sure to B524 BETA 6.0 and B550 Official 6.0 (available in Europe) :

1. Download : http://consumer.huawei.com/pl/suppo...0=Mobile Phones&key1=Smartphones&key2=ALE-L21

2. Extract 1.zip package and go to the first folder ( .\1\ALE-L21 Northeast Europe Channel Rollback upgrade package for ALE-L21C432B524\01 xbl(Downgrade Downgrade Packages) )

3. Copy folder "dload" to the internal memory (probably you may want to use microSD card however I used internal memory)

4. Make BACKUP!

5. Make sure you have backup!

6. Turn off the mobile.

7. Turn on the mobile by pressing all three keys : vol+, vol-, power button (device SHOULD NOT be connected to PC)

8. Wait untill transition package finishes (takes c/a 3 minutes).

9. You will end up with Build ALE-L21C432B300 (transition build). This should not be used on daily basis as it is ONLY for getting back to Lollipop (see official Huawei materials for details)

10. Delete the contents of "dload" folder in your phones internal memory.

11. Download B190 (or B170 - may also work with others but these two were tested) : http://download-c.huawei.com/download/downloadCenter?downloadId=72585&version=256613&siteCode=de

11. Extract the downloaded archive - open it and copy the "dload" folder with B190 firmware (2,8GB uncompressed!) to the phones internal memory.

12. Turn off mobile.

13. Turn on the mobile by pressing again all three keys : vol+, vol-, power button (device SHOULD NOT be connected to PC)

14. May take couple of minutes (5-10) as the whole firmware gets installed.

15. The device will be automatically rebooted and all user-data will be removed.

16. Enjoy your downgraded firmware :)
[P8lite General] dkonect:
You can install the official update if you be on build (all info is in the pdf in the zip of the update)
[P8lite General] koxyman88:
how to do this on version b525 ?
[P8lite General] dkonect:
Downgrade to single build B052 by fastboot and after directly with the native updater install vendor< B170<B188 and B550(in a dload folder's at root on your internal or external sd)

You can directly jump to B550 since B170.B188.is only a ota update.

Only way without any trouble.

It's because B525 is single sim variant firmware.

This B550 official update is for dual.

But you can use this on your single and use the second sim if you want or ext-sd like now.

If you want help and links pm me.

Also unlock bootloader is need.
[P8lite General] wolfensg:
Yes, I know.

I thought that since I figured out that this "simple" procedure works fine also for Official B550 - anyone that would want to downgrade can follow.

Obviously - after the downgrade it is possible to make an upgrade again at any time.

[P8lite General] pl4t!n:
hi can you help me to get link to b188? or b194 (dual sim.)

my previous version before b550 was b194, if i decide to roolback to b194 again, the roolback process is the same? just update the roolback upgrade and then donwgrade to b194 or b188?

i think i found something and correct me ir i wrong,, since b188 or 194 is an OTA package, my device needs to be running B170 i am right?

[P8lite General] wolfensg:
In order to make a downgrade you need to download the full (this 1,5GB+) firmware (be it B170 or B190 as I tested). Having a small OTA patch only would not be enough.

But anyway - once you flash B300 transition package on Android 6.0 and then flash B170 you should be able to get an OTA with the rest (if not - you can always flash newer ones through Local Update).
[P8lite General] pl4t!n:
Ok, but do I need to apply rollback upgradr or I just need downgrade b170 .

[P8lite General] wolfensg:
If you are downgrading from Android 6.0, first you need to apply the B300 transition package and THEN B170 or B190 full package (see the howto in my first post for details).

[P8lite General] amageek:
You'll be needing a rollback package ( a transition rom) , then from there you can head to any lollipop build...

Download this rollback package

Now extract it and you'll get a folder named dload or just update.app file (~200mb - 300mb). If its later, put the update.app file in a folder named dload and copy it to the root of the sd card. Dial *#*#2846579#*#*, a context menu will appear and select SDCard Upgrade, the phone will restart and upgrade.

By doing this, you'll get into the transition rom.

After that download your required firmware (b190 or b170), extract that and do as you did earlier with the transition package..

Done

Next time, correct command is the following:

Fastboot flash recovery twrp.img

You tried to flash the recovery image onto the kernel/boot partition, luckily it doesn't allow this, unless it's an actual kernel image fitting that partition. ?
[OnePlus 2 Q&A, Help & Troubleshooting] Spannaa:
Actually, fastboot boot twrp.img boots the TWRP image without flashing it.

fastboot flash recovery twrp.img flashes the TWRP image to the recovery partition.

Both are valid commands and have their uses.

fastboot flash boot twrp.img would be the command to try to flash the recovery image to the boot partition and shouldn't be used.

Please help
[OnePlus 2 Q&A, Help & Troubleshooting] pitrus-:
Are you sure you flashed the correct OOS3 bootloader compatible version of TWRP? Latest official 3.0.0-2 should be compatible.
[OnePlus 2 Q&A, Help & Troubleshooting] bhanuodin:
how do i flash a bootloader? problem is that i am unable to flash/write on recovery partition. every time it gives the same error mentioned above.
[OnePlus 2 Q&A, Help & Troubleshooting] pitrus-:
The bootloader (also called fastboot) comes with the original ROM. In your case you're already on the newer bootloader since you flashed OOS3 which means you will have to flash recoverys and ROMs compatible with this newer bootloader.

This TWRP should be compatible

https://dl.twrp.me/oneplus2/twrp-3.0.2-1-oneplus2.img.html

Also you can't run ROMs not compatible with this newer bootloader (which means pretty much any ROM that's not using the official Cyanogenmod source tree for building). That is except for OOS3 or newest HOS of course since these are made for the newer bootloader. :)

However I would say the error message you get might be caused by bad cable, faulty driver setup, faulty fastboot tool version or in worst case damaged partition layout on phone. The last one can be fixed by the Qualcomm OOS2 factory restore solution.
[OnePlus 2 Q&A, Help & Troubleshooting] bluesteve3:
Hi, i am having the same problem.

some background: I was on Oxygen OS 2.x.x, i wanted to upgrade to Exodus 6. I had the older version of TWRP. So I tryed to install the new twrp image within twrp. When i rebooted i couldnt boot into twrp, receiving the same error message as in OP title, when using fastboot.

Using the tool all in one toolkit I was able to flash stock recovery.

But I still cant flash Twrp.

I can still boot into system though.

Any advice? Thanks.
[OnePlus 2 Q&A, Help & Troubleshooting] pitrus-:
That explains why you're having problems. You're doing it the wrong way.

First you must upgrade the bootloader by either flashing the convert to Marshmallow zip file which also installs the correct TWRP for the new bootloader (easiest way). Or you could flash the latest official OOS3, then fastboot flash the latest TWRP and from there format system and flash the ROM that's using the newer bootloader.

Hi everyone,

Complete and total noob with Android / ROM's, just converted from iphone to a nexus 5x. So naturally, I've begun hacking this device. Figured out how get TWRP 2.8.7.2 onto the phone, and I've used ADB (macbook pro, El Capitan 10.11.4) to get the file image-bullhead-mhc19q.zip onto the phone.

When I select this zip, and swipe to confirm Flash, it throws the error in red: Could not find 'META-INF/com/google/android/update-binary' in the zip file

I've downloaded the following tar file, 6.0.1 (MHC19Q), direct from the Google Factory Images web page. When it downloads to my mac downloads folder, I open it, and then compress it into a .zip file. Then, I push it over to the device using ./adb. Am I doing something wrong with the tar to zip conversion?

Can not seem to figure out how to get over this hump, and any guidance is gratefully appreciated!

Thanks, Craig

Read the flashing instructions at the top of the factory images page. You're supposed to flash the factory images with fastboot from the bootloader, not from recovery.

[Android Q&A, Help & Troubleshooting] L3R0N:
I don't really know how much the version matters. For example, I have never gotten a ROM built for the 2.6 kernel to run on my device which uses a 3.1 kernel version even though they both use the same SoC. However, I have gotten ROMs for kernel version 3.4 to run pretty fine on mine which is kernel version 3.1. Some will work and some will not. If you are going to try porting your own ROMs then its important to not be afraid of getting bricked...that happens. Porting is mostly trial and error until it works.

Yes by Soc he means processor. Stock refers to the ROM your phone came with. If you want marshmallow, find another mt6582 device that is similar to yours which has M and try porting using the guide I pointed you to some posts back. The kernel you would use in this case is the kernel from your stockrom. You would of course need to modify it's ramdisk to try and get M to boot. As I mentioned before, it is trial and error and when doing this you must not be afraid of a brick.

[Android Q&A, Help & Troubleshooting] L3R0N:
There are existing roms for your phone including CM12.1. See here. In you wanna diy then you'd need a tool to extract the ramdisk from the boot.img. I use Carliv Image Kitchen, it's available here on xda. You also need a tool like notepad++ to edit the files inside the ramdisk (init.rc and the rest). The idea is to compare the two and make changes to yours based on what's in the other (boot.img from the ROM you are porting) ramdisk. As I said, it's trial and error. If your device is really similar to another device as in they're basically identical twins then you can simply replace the boot.img with yours and modify build.prop to fit your device and you are good to go. But that's only if your devices are very very similar...like the Galaxy Tab 8.9 and the Galaxy Tab 10.1 they're basically the same device with some differences in their kernels hence you replace the boot.img in the ROM you are porting with one from your stock (modified accordingly of course).

When I was using Podcast players on MIUI roms there was a problem that the podcast never resumed from the last position.

This seems to be a mediatek problem combined with long audio files.

There is a workaround using Podcast Addict, where there is a setting to "fix mediatek resume", but this fix seems to only work on Android 5.1 + and since MIUI is based on Android 5.0 it does not work.

[Verizon HTC One (M8)] andybones:
I don't think SunShine supports Android 6.0 MM for M8 (could be wrong... I'd ask in their thread). It could come soon though, as they just released v3.3 with VZW M9 MM support.

If it is S-ON and on MM and SunShine doesn't work, you can go to the M9 JavaCard thread and get it S-OFF sending it out. So you aren't stuck, luckily but it may be a bit more of a hassle than being able to do it quickly using Sunshine software.
