Stuck at B300 rollback rom - P8lite Q&A, Help & Troubleshooting

Hi
I just tried to roll back to 5.0 rom and now I'm stuck on b300. I installed it but when I try to install official rom via dload it will just say it has failed. The problem is that I have locked bootloader. Yes now I know how bad idea this was... Is there any hope for me?
Edit okay now it seems to work. For anyone else having this same problem. That you can't restore your software. The key is that the update.app needs to be update.app and not UPDATE.APP or update.APP (I thought it wouldn't be that stupid that it would be case sensitive but oh well!)
Sorry for everyone if I cause trouble.

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?

Yes, I did.. :good:
Updated and rooted!
Thanks, this method really works! http://forum.xda-developers.com/android/development/guide-install-twrp-root-systemless-t3325161.. I come from the ROM fRomFuture release KW45; really this update was a hard process in the first tries, then I want to share the details because the tools in various posts of P8 really did the miracle (he he):
1. First, I did flash the boot.img and the recovery.img from the release B200, more exactly from the ROM “GRA-L09_C432B200_Firmware_CEE&Nordic European Region_Android 5.0_EMUI 3.1”, of course, with the “Huawei Update Extractor tool”
2. I put the update.app of the B200 release in the dload folder in my external sd card, then I rebooted the device with the 3 buttons pressed (or best, firstly I have powered off this then I reset it with the 3 buttons pressed)
3. My GRA-L09 took quickly the update.app and finally this made the update, with a little message of error at the end, I don´t remember, at the 85%?, but this rebooted with a fresh installation of Marshmallow..
I update it with the ROM “Huawei_P8_Firmware_GRA-L09_Android 6.0_EMUI4.0_C432B321a_Bulgaria”, this detail in the attachments that the versions reliable for update are, the B200, B313 and B317
Finally, for the question of this topic, the only version of TWRP working for this release of android is the new_twrp.img in the forum linked at the first. I've tested others as the twrp-2.8.7.0-p8.img without success
Good luck! :good:

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.

Bricked p10+.. Need help..

Hello fellows. I am in a deep sh&*. Maybe someone can help.
I have a p10+ L09 converted to L29, rooted, bootloader unlocked. It was on rooted stock rom. Yesterday, tried to make the update, and something went wrong. Now, I can't install any rom exept future rom or something found here. I've tried rayglobe knife, Huawei multi tool, eRecovery, dload, and no way to install an official rom. I am barely able to install twrp, format data, and install future rom before rebooting.
Tried to extract boot, cust, system from the original rom, but it says finished and bootloop just after the unlocked message. On latest versions, I cant even find them in the update.app..
Any help, any downloadable file or link is really appreciated. Please help...

What error/behaviour are you getting from erecovery?
Plop
Hello mate. Thanks for your time.
ERecovery crash everytime at 5%. If I try to download via erecovery, it doesn't download.
I've tried to extract the files from update. App, and inject them via fastboot. It goes to the end of the operation, but once rebooted, it bootloop before the Huawei logo..
I don't understand what happens.. It's like if the phone don't want the original firmware anymore..
If you have any files to propose me, I really want to try tonight...
Can you somehow recover your original oeminfo with TWRP and retry erecovery? That's how I got out of a similar situation, although I can't say for sure whether I really had the same root cause.
Hmm not sure that the oem info is ok or corrupted...
That's what I am affraid of..
I will try in a moment to see..
If it's corrupted, that means the phone is dead?
In that case you could try funkyhuawei, they provide their own oeminfo and erecovery connection. They do cost money though.
May I ask what makes you want to go away from the fromfuture ROM?
This... Android 5.1, emui 3.1
I don't know if iam becoming stupid with age, but can't find any more recent... And with the kids yelling on my back.... Lol
Well, I found a recent rom from future. Had some troubles with Android locking magisk, but now it's working ( update magisk before putting your Gmail account and restore). For now it's working fine. Just had a few freezes here and there but since this morning it's going fine. I think I'll stay with it for now.
Thanks for the people who tried to help me.

Hello man,
did you removed prevoius update.app from SD card, the one from rollback??
Maybe you forgot to do this...
If you sure you done all things right then take a look at the UNIFIED HELP THREAD...
At 6th post you'll find a L31 rollback package that will give you C900B300 global firmware.
From this flash C636B170 full ota and see if worked this time....

Hello dude,
in the guide i never readed to use the toolkit, that's another way i think...
Flashing the rollback package will bring you c900b300 firmware wich means global intermediate transitive firmware...
Create a dload folder in SD card, extract update.app from rollback package and put in it.
Turn off you phone. Now disconnect from PC, and let it start keeping vol+ vol- and power buttons.
When it ends turn it off and remove the SD card and the update.app from dload folder.
Download and extract update.app from L31C636B170 full update.
If you missed it...
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1164/g104/v66846/f1/full/update.zip
Put this in dload folder in SD card again and put in your phone...
Repeat vol+ vol- power buttons and it will flash...
Recommended: when finished reboot to e_recovery (vol+ power buttons) and factory reset.
If all gone well you will stay now on marshmallow firmware..
Wish you the best my friend...:fingers-crossed:
Edit: flash the rollpack package suggested in prevoius post.
All credits goes to @dariomrk and other contributors that create the thread.
Thank you guys.
