Stock Recovery?

[sinf1x]

Does anyone have or know where to get a stock recovery image for the BTV-W09?

When I flashed the US "003" update manually through the dload folder method, my TWRP was replaced by the stock recovery. I have left it there, and since flashed TWRP to recovery2. The update failed, but I ended up with stock recovery and the tablet no longer rooted. I would try that first. If that doesn't work for you and if you are on the US version "002" firmware let me know and I should be able to send you a backup of my recovery partition bit if you need the eRecovery from the recovery2 partition, I will be unable to help you.

I am on the US version “003”, I updated before flashing TWRP and rooting. TWRP was flashed recovery not recovery2. No worries though, Im sure someone will post a recovery as rooted people will be needing to flash OTA updates soon.

If you are on "003", try updating the unzipped "Update.Zip" from the dload file. I found a copy of the update.zip on my internal SD in directory called HwOUC. If you can't find it, I still have my file. The Update will most likely fail, but that should give you the standard recovery back. then I suggest you flash TWRP to Recovery2. TWRP actually is easier to access from Recovery2 becuase all you have to do is hold the volume up key down for a few seconds from the unlocked bootloader screen to boot into TWRP. Once you have TWRP re-installed you can then just flash the super user zip file to regain your root.

I am not sure if it is because I now have unlocked the bootloader, have recovery2 with TWRP or updated the file to enable the 5Ghz modem , but even with having the standard recovery partition back my system did not pass the altered system check and allow me to flash the OTA. I am not quite experienced enough to try and use Flashfire to force the update, since there is a warning about Huawei devices being easy to hard brick. Hopefully someone who has updated and then rooted will post an .img file of the updated system partition so it can be flashed with TWRP (at least I think that is what those of us who have already rooted will need to do).

I looked for the update.zip but it doesn’t exist anywhere. These updates are usually removed after the update completes successfully. Plus I’ve done a factory reset since updating, which may have deleted it. I wanted to see if enabling the 5GHz radio would stick after the reset (it did). The 5GHz radio hack was really my only reason to root. I didn’t alter my system partition with TWRP, so I may still be able to take an OTA update if I had the factory recovery. Ive stopped rooting all of my non Nexus devices. Since Google releases almost monthly security updates which usually unroots anyway it’s just too much hassle to keep root. If you want to post the update.zip somewhere I could give it a try, if not that’s cool. Im sure a factory image will be available at some point.

I have posted the Update.zip file to the following location:

Let me know how things go.

Coming from a Nexus 7 I'm use to many of the img files you flash for restoring.

Using update extractor I now see many of those files (003 update) and some I have no idea about or how to flash them.

BOOT.img - OK
CRC.img - ?
CURVER.img - ?
EFI.img - I know what EFI is just never flashed it on an Android device.
FASTBOOT - OK
FW_HIFI.img - ?
FW_LPM3.img - ?
RECOVERY.img - OK
SENSORHUB.img - ?
SHA256RSA.img - No what it is normally but never flashed.
TEEOS.img - ?
TRUSTFIRMWARE.img - Interesting, but have no idea. - ?
VERLIST.img - ?
XLOADER.img - ?

Like many of us I'm in the same boat. Unlocked, Flashed recovery and rooted and cannot install update 003.
I've flashed the recovery.img from update 03. I've done a factory reset a few times. Odd enough it maintains 5Ghz wifi after doing a reset. I'm stumped and not sure of so many of the other .img files. Might one of them help me get the update to pass if I flash it. That or we wait for a full release and not an OTA to grab all the files we need. Really think I need system.img to make it work but the update doesn't include it.

Thanks johe for providing the 003 update.zip. I may try flashing the recovery.img this weekend. Ill let you know how it goes.

Jmjm003, I believe the issue with updating with the OTA is due to changes detected in the system partition after rooting/unlocking. Im not sure of a way around this other than flashing the full system partition, and we don’t have the factory ROM available yet. Im also new to Huawei devices and their partition structure so hopefully the development community will grow around this device and provide better solutions. I also can confirm the 5GHz stayed enabled after a factory reset, the question remains would it hold after an OTA update.
