Tab Mini C boot loop. Help please.

yeah, it is SDM662 and this device is able to 9008 because there is no secure boot. I could provide the firehose if needed.

You can try adb sideload (I never have).
If that doesn't work, we can try the flash drive method.
That works with update-binary, but I've never tried with this new update engine.

I already tried adb sideload as per this advise.
But the verification of the update fails.

Do you mean an external drive at USB by "flash drive method"?

[Wolf-HRB]

I think he wants you to use adb sideload or apply update from SD card

I was talking about using an flash drive and a custom recovery.
But I've never tried using the new "update engine".
It looks like you could put the payload.bin on a website or flash and update from there.

Edit: Oh, I see there is a new Poke5 update.
I guess that I can experiment with that on my Poke5.
It's a mixed bag, I guess, of whole images and payload.bin
I think that the update_engine only works with payload.bin?

Unfortunately my internet is mega-slow, so I can't download 1.6GB in my lifetime.

Since we have found a new Firehose loader for the Poke5 there's no risk.

I'm using a Netgear LM1200 4G modem, rooted and with custom JSON status that I use for a monitoring app. The debug UART is brought out to a connector.

When I'm in the country the congestion can be bad at times. I downloaded the Poke5 update this morning at 3:30 AM without a problem.

We're making a bit of progress, but still bugs.

Edit: Oh! It does work!
The stock boot works, but I'm having problems with Magisk now.

Sigh, well at least I can read my book.

Edit^2: Ok, I got Magisk working again.
I was shadowing framework.jar and it was the old version.
An update fixed that.

That sounds very promising. Being able to read my books again would be amazing.
So if you have anything for me to try, please let me know.

I'll be making a new recovery, but the short version of how you do this:

• Go to fastboot and determine which slot you are on.
• Flash custom recovery to the current slot
• Reboot recovery and see that it behaves correctly
• Flash custom recovery to the inactive (other) slot
• Get update.upx, decrypt, unzip on desktop (no payload dumper needed).
• Put payload.bin & payload_properties.txt on a FAT-ish flash drive
• Reboot recovery
• adb shell start autoupdate
• Remove USB cable, plug in OTG/flash
• Drink a coffee, watch the little LED on the flash blink
• Put the flash in the PC and look at autolog.txt
