Upgrade to 5.1 beta?

Hello Everyone, I have ALE-L21 and my current firmware is C185B130 (apparently C185 is UAE region but i live in pakistan). Device is bootloader unlocked, rooted with TWRP installed.
I have a TWRP backup of current rom. I wanna try the 5.1 beta released for Europe but it says here ( http://forum.xda-developers.com/p8lite/general/beta-firmware-p8-lite-ale-l21-c432b008-t3243228 ) that i need C432B132 to upgrade to this. So I downloaded this firmware(C432B132) from Huawei website. There were two folders in it, dload and CUSTOM(not sure what that for). I extracted system.img, recovery.img, CUST.img, boot.img from UPDATE.APP given in the dload folder. So here is what i'm thinking.
1) Flashing the extracted system.img, recovery.img, CUST.img, boot.img would get me to C432B132?
2) After i install B132 can I upgrade to 5.1 using EMUI local update?
3) If something goes wrong, can I just flash TWRP and restore the backup?
-
Or this whole idea is foolish and i would screw up my phone after flashing system, cust and boot of some other firmware designed for some other region???

No this is wrong
1. You need to downgrade to B052
2. Install B136a
3. Install B008(Android 5.1.1)
After each install is recommended to make wipe

Thanks

I dont think that you need to go all the way to B052 and then flash the required version
This is what i did:
1) Flashed 132 cust, recovery, boot, system. My build number changed to something like balong ( I dont remember exactly :silly: ).
2) I flashed the UPDATE.APP file that was in the CUSTOM folder (that came with B132 rar file) via EMUI and it restored my build to B132.
3) Tried updating to 5.1 via EMUI but failed.
4) To give it a last try, I downloaded and flashed my phone with CUST, recovery, system, boot.img of B136a and then the update worked. My phone is now 5.1.1 B006
Thanks for the reply mate :good:

yeah its working fine. I think the battery life has improved a little bit or maybe it is just because i haven't installed much apps after flashing this rom compared to when I was using the B130. The only thing i miss from B130 is that small 2g, 3g written on the signal bars. This one only shows the 2g or 3g network type when the mobile data is turned on. Huawei cloud is also not present in it so you may wanna backup your contacts and stuff

Give It a try. If i doesn't work then you can just flash 132->136 and then apply update. But there maybe some problem with the version number changing to "BALONG". I faced this problem when I flashed 132 over my 130 but then I applied UPDATE.APP file(the small file in the custom folder) via EMUI Updater and it fixed the version number. But the 136a rom did not had any UPDATE.APP in custom folder so I dont know what to do if you get a version number problem. You can try flashing the 5.1 update via EMUI and maybe it will fix the version number problem (if it happened in the first place) or you can always goto 132->136 and apply 5.1

yes you need to unlock the boot loader. What exactly do you mean by double tap issue? are you talking about the double tap to wake feature not working sometimes? Yes the DoubletapToWake dont works sometime which can be very annoying so I just disabled that feature and using the power button ever since. As for the typing issue, No I'm not facing any typing issues, never did on the B130 and not on this 5.1 version. Try using someother keyboard app?

I have c185b130, there is c185b131 update on consumer.huawei.com for UAE region uploaded on 31-12-2015, will it work on my device? What are the changes in c185b130 and c185b131?

Dload fails, AL10 device is NRD90M test-keys. Solution.

Does your MATE 8 Chinese no longer make the EMUI 5.0 donwgrade? In the system information, does it appear as NRD90M test-keys? Simple, but a detail that goes unnoticed. The files that have been circulated to any MATE 8, including international ones, have two ZIPs, one with the UPDATE of the system and one usually with that name, "update_data_full_all_cn.zip". This file can serve in the international, but not in the AL10 that become NRD90M, for these, it has to be a file with that name, "update_data_full_dualcu_cn.zip". Download, unzip and dload with its UPDATE.APP, its AL10, to be recognized again by the system. Now back with a NXT-DL00C17B523, running themes, playstore, magazine ... etc ...
https://drive.google.com/file/d/0B7ffjC1YBlzxNnpGbWsxY3Y0Vm8/view?usp=sharing

So its mean that we can flash emui 5 in b386 with dload in sd card?

For some users u have to write an step by step guide how u come from NRD90M to B523 like this

Well, recovery has to be working. If your bootloader is unlocked, use the fastboot to send the recovery of your rom where you are trapped, you will probably have access. The command is...
"fastboot flash recovery recovery.img"
If your device is a DL00, you have to extract the zip and use UPDATE.APP from it on your dload in sd card.

can someone send me the real link for NXT-l29?

Blocked downgrade (or upgrade) in Huawei P8 Lite Dual

Hi! I tried to downgrade my P8 Lite (DUAL) from ALE-L21C432B574 firmware (West European), Android 6.0 and emui 4.0, to Android 5.1, emui 3.1.
The downgrade failed and after restart, the device have emui 4, android 6.0 but firmware ALE-L21C432B132 that, normally, is for android 5 and emui 3.1. Now, as result (I think this is the reason), I cant to update neither downgrade, in any way my device: I'm stuck in this situation ...
Any idea about how can I do to solve?
Thanks in advance for any advice.

and have a unlocked bootloader and have code if needed
sombody can help me plz can't figure it out now
mayby thanks arrowbow

First of all...
Restore your TWRP backup to get your OS back to work.
To downgrade from Nougat, you really need the RIGHT files.
So start by telling us which phone you have (L31 or 21?).

if you haveb't a twrp backup you can go to fastboot and flash system.img boot.img cust.img and recovery.img

Yea, but before flash oeminfo via twrp

k i have huawei vns-l31 i don't have any backup so thats the problem i forgot to make it thats kinda dumb

i only have some .zip file no .img files

Flash OEMinfo, then install version B150 (for me, it ONLY worked with B150 no other version) with the three button method.
Copy the update.app into DLOAD of your SD card with mounting storage in TWRP.

Use a translator to find the link for L31 firmwares.

You updated to Oreo, correct. Of course you did.
The update.zip has inside (extract it) update.app. use heawei update extractor to extract that file. You will get the system.img there. That one will be the correct one for your model and build number.
If yo I updated from regular ota, you may not have this zip file
If this the case you. Will need to download it. From pro-teammt.ru

You updated to Oreo, correct. Of course you did.
The update.zip has inside (extract it) update.app. use heawei update extractor to extract that file. You will get the system.img there. That one will be the correct one for your model and build number.
If yo I updated from regular ota, you may not have this zip file
If this the case you. Will need to download it. From pro-teammt.ru

it is there. her are the three update file links.
you "should " only need the one main "update.zip" file to extract system.img
but can use all three to make full restore

Downgrading to Nougat is not recommended, because EMUI 8 is Treble supported.
That means it has dozens of new partitions and partition lengths. Many people have screwed their phone trying to downgrade.
Unless you have foolproof method of downgrading and correct 'downgrade firmware' (yes, it's different, cause it will re-write all the partitions again), Don't do it.

try this in fastboot mode:
Code:
fastboot oem relock [your bootloader unlock code]

I have a similar problem and I cannot get back to stock from the RR oero
I used the method to upgrade from 5.1 to oero 8.0 here https://forum.xda-developers.com/honor-7x/how-to/guide-honor-7x-flash-oreo-update-t3781649/
Then used the Openkirin RR install method using stock recovery. - all goin good but RR has to many crashes.
I have tried to roll back to Stock using the same HWOTA method putting the update files int HWOTA 8 folder, all looks good in twrp and I wipe Cache and Dalvik but it still reboots into RR
I've noticed in Twrp in red letters it says cannot find partition /system
Rebooting into recovery after using to install TWRP it first boots into stock recovery then when i press factory reset it will boot into TWRP.

Need help with extracting system.img

I have installed Lineage OS Treble GSI via fastboot and may want to return to STOCK EMUI 8.0 in the future but I have a chromebook and can't use the Huawei Update Extractor Tool(Windows app).
Would you be willing to download the "update.zip", extract and post the "system.img" extracted from the "update.app"?
I need the "system.img" for Huawei Mate SE BND-L34C STOCK OREO 8.0
I searched XDA and GOOGLE for the STOCK Mate SE system.img but unable to find.
ANY HELP WILL BE APPRECIATED, THANKS IN ADVANCE.
