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?

Huawei P9 Lite VNS-L31 Problem

Hi guys,
I would like to ask help with the problem I'm facing with my Huawei phone.
I had EMUI 4.1 which was in Stock Marshmallow and I updated it to the EMUI 5.0 | Nougat 7.0
THEN, I tried to flash a Revolutionary TWRP Nougat B.9 and it was ok, but then when I flashed SuperSU from onhax.me it got stuck on the part where it says
" Your phone has been unlocked and unsafe ... "
It was stuck there for almost an hour and thought that it is now softbricked. So I made a move of flashing bunch of ROMs that I thought that would fix it, the last ROM I tried to flash is RevolutionROM-P9Lite-B161-RC3_17-11-16
It seemed like it flashed it fine but says
Updating partition details...
mount -o bind '/data/media' 'sdcard' process ended with ERROR: 134
So I rebooted my phone and it went to
Your device has been unlocked and can't be trusted.
To learn more, visit:

-------------------------------------------------
(1) Press Power key to continue
(2) Press Volume Up key up to 3 seconds to enter erecovery to restore your device.

^ It shows that screen twice and after the 2nd boot, it goes to Huawei eRecovery which I think is the stock recovery for my phone.
Now I don't know what to do with my phone, I don't know what ROM I should try to flash, I don't know how I can restore my phone back.
Does anyone know what to do in this kind of situation?
Please, I need help

If you have no /dload/ folder in your sd card, and your are not connected with usb, a boot with 3 buttons method should be boot on TWRP.
Then flash oemInfo and put the update.app of the version of your choice in /dload/ folder in sd card and boot with 3 buttons method
(Sorry for my bad english i'm french)

Mate 8 not working properly after erase data from TWRP

hi guys, hopefully someone can help me with my situation. I try to explain as best i can.
My Device: huawei nxt-L29
Build number : nxt-L29c636b585
( I install right firmware for my phone )
1. i follow this guide (https://forum.xda-developers.com/mate-8/general/guide-unlock-bootloader-root-install-t3301371 ) to Unlock Bootloader, Root, Install TWRP & Decrypt.
All working perfectly until last step "Decrypt",
Instead of format data - type yes... I do my mistake by click Advance Wipe and click Erase Data. And the phone stuck on loop bootloader.
2. I try to flash stock recovery for nougat and flash UPDATE.APP on EMUi recovery but failed.
Then I follow this guide for huawei p8 because i cannot find any related entry similar with my situation in Mate 8 forum ( https://forum.xda-developers.com/huawei-p8/how-to/guide-how-to-unbrick-huawei-p8-failed-t3260704). And use Huawei Extractor to extract boot.img, system.img and recovery.img and flash it in fastboot mode.
All work perfectly and my phone restart like normal.
3. The problem after my phone unable to lock gps correctly (cannot use all because always changing position),cannot turn on bluetooth and unable to change ringtone/notification, and maybe a few more problem. i think its because I didnt flash all file in UPDATE.APP.
4. The question is how do i flash UPDATE.APP and get it fully work, because if i flash on EMUI recovery it always failed on 1-5%? Just for info in Update.app, there is 2 recovery image which is recovery.img and recovery2.img, do i need to flash both to try flash on EMUI again?
Hope you guys understand me,i not english speaker...Thanks,
any question just ask below.

Opening one topic will suffice :good:

The mate 8 actually has 2 update packages, the undate.zip and the update_full_hw_eu.zip, both need to be flashed, can be done via twrp, I suspect you are also missing settings like update and apps like file manager, I've done it the way you have and ended up with that problem

P9 lite No audio After TWRP restore Dload failing HELP

[SOLVED] Hi i was on l-31c432b381 firmware with emui 5.0 and android 7.0, i have unlocked the bootloader for install magisk 12.0 and have root permissions, after months i saw an update for my phone (b389) so i tried to upgrade but i had twrp so error 1 or 7, i flashed the stock recovery, redowload the update and the install failed at 5%, so i tried to unistall magisk before update, but nothing it wont update, after few tries the upgrader says that the update now is not 300mb but is full and is 2gigs, so i think is the time.. but no. so i tried to force the update with 3 buttons recovery dload method but it doesn't work at all 5% at every try. so i searched for support and i found that the ota connot be installed on unlocked devices, so i tried to relock my bootloader with oem relock and the unlock number but it says root type is risk... so i can't even relock my bootloader.. other says that i have to install to relock or can relock... but is b381 the stock? or they instend the mm version? i don't remember what version p9 lite ships. i tried to flash imgs through fastboot but even if i flash system and boot of the b389 the system boot and the info are of the b381, unisatlling app system crash, so i restored my previous backup made through twrp recovery, i immidiatly noticed that the huawei boot animations was gone and was an android stock animation. i thinked it was fine and all was working properly, i give up o upgrade and i was fine but sad. after few hours i tried to make a paper copy with my printer that have nfc but my phone keep shows and hide nfc symbol like on off on off on off over and over even after reboot, after a call i understand that the audio doesn't was working, every type of audio not work even the mic. i don't see any other problems but without sounds is unusable as a phone or mulimedia things... sorry for bad english please HELP i tried all i founded ...

Hi, my english is bad too , B389 is an OTA update, its impossible upgrade via fstboot or via TWRP (error 7). IMO the right way to fix your problems - downgrade to MM , then back to Nougat etc. (remove pattern Lock , Fingerprint lock, root etc. before installing downgrade). It will erase all your phone data!!!

and download MM firmware VNS-L31C432B161 (Single SIM)
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1164/g104/v66022/f1/full/update.zip
1) Create a new folder dload in root directory of SD card (root directory : it means dont put it in any folder .) Now unpack the rollback package and copy its contents “UPDATE.APP” to the “dload” folder. Use the 3 button combo installation. After your firmware version should now be on “B300” or "test-keys".
2) Remove from dload folder rollback package, extract the ZIP file with MM firmware to the dload folder and use 3 combo button installation.
Or you can use this method : on your phone launch the phone dialer app and dial *#*#2846579#*#*. Next, select Project Menu – > Software upgrade – > SDcard upgrade – > and confirm the flashing process that is about to be initiated.
Good luck!

Hi, my english is bad too , B389 is an OTA update, its impossible upgrade via fstboot or via TWRP (error 7). IMO the right way to fix your problems - downgrade to MM , then back to Nougat etc. (remove pattern Lock , Fingerprint lock, root etc. before installing downgrade). It will erase all your phone data!!!

Yes, you can. Via OTA, or you can use TWRP (Meticulus 3.0.2.0 only ! ) and flash both .zip files. You must download two files:
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G753/g104/v80474/f1/full/update.zip
and
http://update.hicloud.com:8180/TDS/...-L11_hw_eu/update_data_full_VNS-L11_hw_eu.zip.
In TWRP set Install, then select memmory SD card, and klick on
update.zip, confirm installation. After, STAY in TWRP, go back to Install, find file ...hw_eu....zip , confirm installation. Then select rebot system. Done!

Try it, but I think, you will get a message "not compatible" . Via dload its impossible, IMO use rather Huawei firmware finder or wait for OTA update.

If I said, it's impossible manually update to 381 or 389 using OTA firmware, trust me . Try Firmware finder. GL!

FF works with proxy fine, but you must first download and install Firmware finder proxy apk. On Nougat use TWRP 3.1.0-2.
