Does installing this version still cause bootloop and bricking issues for BT HomeHub 5?
Do you think I should upgrade from version 21.02.6 to this version or not at all recommended?
I have one more question, is it possible to brick my router in all versions of 22.03.X?
What should I do to stay on version 21.02.6?
You must not keep any setting when upgrading the BT hub to the 22.03 branch because of the switch to DSA. I'd suggest backing your existing settings up first.
I've tried the patch with my own snapshot build plus the 5.15 testing kernel and it seems to have cured the bootloop, even with lots of extra packages included which previously made prolonged bootlooping occur most boots.
I think it may be taking just a few seconds longer to boot than my previous build of 22.03 which I'd used a workaround to avoid the boot loop.
So, in your opinion, should I update version 21.02.6 step by step or can I update to the latest version 22.03.4 without any problems?
Sorry, I didn't understand what you meant by this problem. This means that this problem has been patched in all 22.03.x builds
I don't want to lose my device
So please guide me , Why this problem has not been solved yet on the Openwrt website!
The required patch is included in only the 22.03.04 release (plus current snapshots), do not install previous versions of 22.03.
I haven't tried this actual release yet, so I would suggest perhaps waiting for someone else with a bt hub 5 to try it and confirm that it is working before installing yourself, as it sounds like you'd not want to do a serial console recovery.
(I did find that in boot looping builds that the bt hub would often boot successfully after a few hours)
Remember not to keep your settings if/when you do install it.
Version 22.03.4 successfully installed for BT Home Hub 5A
Upgrade From 21.02.6 => 22.03.4new
and thanks for your help and all dear Openwrt developers & ... Fortunately, the boot speed seems to have improved, but I hope that I won't face the problem of Boot loop in the future, because I encountered it once in version 21.02.5, and after a lot of effort, the device was able to boot up. It's just that the initial installation took a lot of time compared to the previous versions, but the reboot is better.
reboot time : 45s
erase factory time : 1m,5s
Please do not install versions 22.03.0 - 22.03.3 For BT Home Hub 5 / Plusnet Hub One under any circumstances, there is a very strong possibility of bootloop and bricking.
While the resolution has been submitted, it does leave a gaping hole for those that are affected from migrating from "stable" builds 21.02.x, 22.03.x to now the intentionally "broken" 21.02.6 and 22.03.4 builds. Not sure how the affected users would feel to migrate to the snapshot builds since the rushed release could have been avoided if the UBI 'build.c' code had been rolled back to the previous state or the published patch in early March was adopted. Being comfortable with the snapshot builds due to inherent long-standing limits with the 5.10.x builds, consistency on many targets adopting the same builds for predictable operation, and concerns over timely CVE roll-outs, it does not have a significant impact for some but will for most. The correct approach should be to roll-in the fix and replace the 21.0.6 and 22.03.4 targets so that unsuspecting upgrades don't lead to soft-bricking of devices when individuals do not understand the scope of the problem noted in the forums and blindly sysupdate by clicking on the links on the wiki. Not a professional approach.
Another RT3200 updated successfully. Thanks, devs!
An ongoing issue I've been having may have been fixed: dropbear came right up on the IPv6 listen address. On previous reboots, I've had to log in via IPv4 and restart dropbear to get it to come up on both address families. This is the first reboot I recall where v6 came up without intervention...
