zgfg, it's an honor to come back and resume our useful discussion and posts about phone android problems.
i was very busy that's why we're not being in touch
but now i have now sometimes to myself.
i think our last post between you and i was about
if using erecovery we do loose bootloader i did find
a way a strange one not letting all firmware downloaded and reboot and that's worked fine for me i did it twice without loosing the bootloader.
And @Ooinaru did try erecovery by downloading all the the firmware same result no lost of bootloader and that's now we know two way get back the thing running normally and smoothly without having to pay or another bootloader code.
today my question is.
is there some post you know where i can get the b550 firmware and flash it manually?
Hi. There is b550 on Firmware Finder but it's not PV (just FullOTA-MF), hence cannot be upgraded by DLOAD
Cannot be flashed either by TWRP:
- TWRP from OP posts was taken from P9 Plus or something (there was no better at a time), it declares that device is VIE (or MHA, I don't recall anymore) and not EVA - since update.zip internally checks for device model (it was the case for b540 update.zip), flashing will fail findinf that device is not supported
- TWRP does not support encryption on Data (and Internal memory), hence flashing the parts of b550 that need to go to Data partition will fail
Only if you could find a newer TWRP for EVA, EMUI 8 on the Russian 4pda forum or some Chinese forum - IDK, no more in the game
eRecovery by itself does not re-lock Bootloader - it is a flag that may be or not in the particular stock firmware package (if it is, updating by OTA would also re-lock BL). b550 is a small update, hence they probably didn't go forcing to re-lock BL.
But even if update re-locks the Bootloader, just reuse your old BL code to unlock once again
There are other sites like androidhost.ru or support.halabtech.com where from time to time you could find the so-called Huawei official Service repair installation package - those are suitable for simple DLOAD installation (you must already be rebranded to AL10 but the phone could be bricked and even BL locked)
But the only Service repair package for P9 Oreo was b528 on that androidhost.ru (up to few months ago when I last checked) - and it works, it's useful for unbricking EVA-AL10 (upon to unbricking to b528, use OTAs to update to b540, or now even to b550)
Maybe one day (with some delay), you will find b550 Service repair package there (they don't call it like that, you must download, un-archive and look if there are official DLOAD instructions enclosed)
Also, you can google for 4pda huawei p9 Oreo or similar - to find Russian forum about. There you could probably find something newer (this thread is practically dead). Chrome can auto-translate Russian posts but to download any file (maybe even to open screenshot attachements), you need to register for their account. And that is tricky - you must pass a captcha you need to know Russian written cyrilics (from a picture - you cannot find an on-line OCR tool to help you to pass the question valid only a minute or so)
On halabtech (put aside their propaganda) you can find from a needle to the train. But from names you don't know what it really is, and to download anything serious or new you must buy the subscription (relatively not so cheap)
