mini review of NXT-L29C432B581 and Guide how to update from NXT-L29C432B560 (no root)

Mini review of NXT-L29C432B581 :

+Better batterylife, remember I use my device hard including gaming (CSR2) and a lot of constant app switching between apps and A lot of IMs. I use the camera, I did listen to music And did cast to my tv.
My record with NXT-L29C432B560 was about 4 hours and 50 minutes (screen on time), with NXT-L29C432B581 I got about little bit over 1 hour more of battery life. So therese is absolutely an improvement in battery life. Besides software other factors determine your battery life keep that in mind.

+Apps open noticeably faster, keep in mind, you must give maybe the system one day or so to fine tune and build up enough cache then you will notice the speed increase. There is no doubt here, apps open faster, especially if they are not loaded in memory before, this was before the weak point with mate 8, fast to open apps if they are in memory but slower if they are not, this update help this.

+ Scrolling is probably as fast before if not faster.

I have not found any negatives.

Instructions how to install NXT-L29C432B581 from NXT-L29C432B581 for dummies

First keep in mind this guide is for L29 not L09.
Also I alsways recommend to install Hisuite on your computer to do a backup include also your appdata with the backups you need to change that manually.
To make backup is easy with hisuite. However this update does not remove any data but if you value your data.. you should consider doing bakcup.

Also keep in mind, this guide should only be used on non-modified devices, no root, no unlocked boot loder or anything cause that could give unpredictable results that I am not aware of.
So do not use this guide or give negative feedback if your device have been modified.

1. Step one Download Huawei firmware finder from google play
https://play.google.com/store/apps/details?id=com.teammt.gmanrainy.huaweifirmwarefinder
And in the app you will have to download and Huawei Firmware Finder Proxy. You do this by opening settings menu in Huawei Firmware Finder as in picture below and this dialog will pop up.
Choose download addon

2. Make sure NXT-L29C432B581 is approved for installation on your device by clicking on "check firmware access" chose "with IMEI"
http://imgur.com/FlT3tsZ , should look like this if it is approved http://imgur.com/eCSFPQo

3. Once huawei Firmware finder and Proxy addon is installed open Huawei firmware Finder
Choose this package http://imgur.com/aKkxRdN
Now we need to prepare your internet connection so you can communicate with the Huawei Firmware Servers.
Click on "Register for update" Click on "register for update it will simply inform you that your IP address have been recorded and allowed for installation from their servers, http://imgur.com/k20UTZF
After that in the "register update menu" now choose "copy DNS", This will place their DNS server in clipboard so you do not have to write it down.

4. In order to install from Firmware finder Server you must use their DNS server this is most likely a security thing. In this Guide I will assume you have wifi. Go to settings and wifi.
Now when you are in wifi settings on your phone http://imgur.com/X16ftl7 now "long press" on your wifi connection a window will pop upp chose now "modify" network"
Now settings for your wifi connection will pop now you will need to press " show advanced options" Now you must set ip settings from DHCP to Static.
The Ip Address you use should be already filled in same with gate the only thing you will need to change is DNS, the DNS is in your clipboard, you now need to long press and press "paste"
http://imgur.com/a/AeXSi (the DNS server in the picture might change so use the one that is in your clipboard from Huawei Frimware finder). Now your connection is prepared now press "save"
Now your connection will restart with the new settings.

5. Now Go Back to Huawei Firmware finder, chose the B581 package again package http://imgur.com/aKkxRdN , now choose " send firmware to updater" This window will appear http://imgur.com/EpiQ2mN .

6. Now Go back to homescreen pull down notifcation bar and press settings, go to the regular huawei update app http://imgur.com/G0xK5Tu now update should appear as a normal OTA update in the Huawei Updater app, click download as a normal ota update. Wait for it to reach 100%. when you have reached 100% and it has verified the package disconnect from your wifi now use your 4G (this to to avoid this problem http://imgur.com/a/9EAAK).

6: Now when you have discconected from your wifi connection which use the firmware finder dns, you now use your normal 4G data which use your own DNS from your own internet provider.
Now its very important to go back to Huawei firmware finder, this is most likely some kind of bug, but it seem do do the trick press "Check firmware access* again. it will send with IMEI but the difference this time is you use your 4G data and normal DNS. http://imgur.com/FlT3tsZ , should look like this if it is approved http://imgur.com/eCSFPQo (use IMEI as first time). Also Press again "register for update" as we did before http://imgur.com/k20UTZF to be on the safe with now this time with your 4G data Ip number (this step might not be necessary but it does not hurt to do this since it worked for me)

7. Now go back to regular huawei firmware updater app. if the package is downloaded 100% press install. Now this is the most critical part of the and all hang of this, now the huawei servers will authenticate the downloaded NXT-L29C432B581 package, it will tell you if the package is 100% genuine or not, if successful your device will restart and update the system.

8. Now the device boots up and NXT-L29C432B581 should be installed on your device https://i.imgur.com/ow6t3pW.png. do not forget to reset the dns server in your wifi connection change back from static to DHCP in advanced wifi settings, good luck.

9. Before you start using B581 go into settings and developer options Now chanage animation speed to 0.5x

Thanks for all you did.
No success for me. Many problems - connection unstable, connection error, authorization failed, no connection with Huawei servers ...
Three times, step by step with guide!
I'll wait OTA.

 

[dante-fu]

Nicely written but it doesn't work on my original, unrooted locked L29C432.
My IMEI seems to be approved since this morning so I hope it means that OTA will follow soon

 

[Cris4524]

No success for me. "authorization failed"

 

[blackinfinity]

No success for me. "authorization failed"

Might be worth to go try multiple times it did only work for me the second day

This method did only work for me the second day so it might not work on first time. It can be little bit unpredictable if the server authenticate or not

 

[bouuman]

worked for me, thank you vermy much! :victory: I had to try 2 times and delete all update files from my sd card which was saved before. I had always the problem after 10% i get this message:
"Software Install Failed!
Failed to check the update package.
Please download the package again".

... but after your fix it worked thank you!

 

[kosmin90]

Doesn't working for me, tried this 5-6 times.

try to do it after your update fails (the 10% thing) and your phone reboots, then dont let your phone download the update and delete the files inside this folders before you do the guide -> ..\HWFF\null and ..\HwOUC , then start the guide till the last step and then start the download of the firmware on your phone, read the guide exactly

Yes this step might do the trick, last try I did before going to bed the server did not accept the package, the day after it did, maybe I did reboot and the last step again... I also think the server is little but unpredictable also.. maybe.. the server is overloaded or something. If this step turns out to work, I can add it to the guide.

 

[Depende]

Worked for me from L29C432B560 rooted with bootloader unlocked.
It worked on the first try.
The only difference from OP instructions was:
1) At 99% I paused the download and disconnect the WIFI to use my 4G connection
2) Open firmware finder; "check firmware access with IMEI" and click in "register for update" (all this step with 4G)
3) Connect again WIFI and finish the download. Disconnect immediately when finish to get the validation with 4G

Thanks!

Great 100 percent and reboot and 4g might work also.

Big Thank you!!! to you :good::good:
Followed all your steps as it is and updated to B581. It took me 1 hr 10 min or so to update using this method.
Previously, when I updated to B581 using a DNS changer app it took me more time. So your method is definite improvement.
Excellent thread & wonderful detailed instructions. :good::good::good:

I wrote detailed step-by-step guide to install Kangvip B588 ROM in my post (https://forum.xda-developers.com/showpost.php?p=72633987&postcount=4291) & I mentioned about you. More people will be using your excellent step-by-step guide in coming days. If you or anyone is interested in installing Kangvip B588 ROM then please have a look. Kangvip ROM is pre-rooted ROM (root is very stable) with lot of features. Please have a look and see if it interests anyone.

Cheers!!! :good::good::good:

I only have made these 2 steps and now I've an update which is proposed to me. I'm rooted with TWRP, so maybe all this tuto is unecessary, like you can see on the screenshots below.

However I think if I have to make this update, I should install the stock recovery and remove the root by caution.

I think I'll test it this week-end to avoid all issues with my phone in the week, because I need to have a functional phone in this week.
If all works, I'll come back here to report it.

I was able to do it without using this method. Here's how I did it:
I downgraded to B152, once system booted, I was presented with an update to B170 through system update, did the update and once booted, B192 was then the next update. Once booted, was presented with the update to B560, right after system started, updater then showed that I can update to B581.

Note, that I stayed unrooted and with bootloader locked through the whole process. It's a pain in the ass to do it this way but it's worth the shot, it took around one hour but your mileage may vary depending on your Internet speed.
