@ilyas rc1-mt7615e-1 to rc-mt7615e-2. I've tried to flash it through wifi from phone 
maybe it caused this problem) I've uploaded openwrt-ramips-mt7621-xiaomi_mir3p-squashfs-sysupgrade.bin on the first screen, that apppears on rc1-mt7615-1 when entering http://192.168.1.1 and that how I get down my r3p here is the last screenshots
@pellmen as much as I'd like to believe that "it wasn't my fault", i'm pretty sure it is. did you notice that the boot message was kernel 4.14.93??!! it should have been 103... maybe it was just the factory.bin file that was botched... anyway, given that brokenness, i'm going to assume that it was a build problem on my part, and not investigate further (and the uart companies give me a kickback...)
i tested sysupgrading from rc-mt7615e-2 to itself and that worked fine... so sysupgrade is fine. transient failure.
this all gets me thinking... it would be really nice to have a feature that says "if we're bootlooping, go back to kernel0 so we can do usb recovery"....
I confirm. sysupgrade is fine
@ilyas here's the log:

[ 6.979941] Rebooting in 1 seconds..
@pellmen haha... congratulations on your new UART! is this what you finally see was going on while the thing was bootlooping? do you know how to use tftpboot? (it's easy once you configure the tftpd server... select '1' in the uboot menu, and use the initramfs-kernel.bin file to boot ... once you've got it up, you can do 'mtd write' again).... sorry the build was bad (again), but knowing that the build was bad, i think this was just a transient problem that won't repeat.
btw, if you're too lazy/bored to setup a tftpd server, you can also press '4' at the uboot menu, and set the flag_try_sys1_failed = 0 flag_try_sys2_failed = 1 (and then save) and reboot into stock recovery (with stock firmware on a usb)... IIRC the syntax is
setenv flag_try_sys1_failed 0
setenv flag_try_sys2_failed 1
saveenv
reset
good luck, and sorry again for the mess-up..
EDIT: just for sanity/safety's sake, you might also want to do mtd erase on all the partitions you won't be writing to completely (as in, coming from stock: rootfs0, rootfs1, overlay... coming from one of my releases, 'ubi')
I'm just learning how to do this😄
@pellmen it's well worth the effort 
much easier to sanity-test a release too (and much less stressful to test new bits when you know you can always recover)
initramf is ok))) router is alive)))
@pellmen hurrah! and now you have learned yet another extremely useful skill! 
(and you know what the mystical initramfs file is for too ;))

@ilyas, yes, all's ok)) I've earned some scheme on mt7615, you can see it here, if you now how to work with *.dsn https://drive.google.com/folderview?id=1-0JlyhbCR8p-jia3POgmnOVvXuhrWOyJ
@pellmen no i have no idea what .dsn files are never learned much about hardware...
btw, i'm curious what speeds you're getting with the r3p... same as stock? how about compared to rc1?
i've put rc1+mt7615e-2 into "production" (gulp...) now if it does something stupid i'll have 50 people yelling at me....

@ilyas, unfortunatly i'm not at home now and can't test it. I've added pdf to previous post with scheme of mt7615 2.4Ghz))) it was so hard to get all these files, becase they cost from 2 to 4 "rd" (the currency of chinees forum to download them). So i had to post leaked 5.0.2.0 driver (they don't have it yet) and wait someone to download it😄 and I finaly get all stuff from that forum))) if somebody interested - here's my theme on chinees forum)

Rather you than me lol..
The wiki is almost done. People can add finishing touch to those. I've filled in most of the items.

@ilyas @PeLLmEn Please check the install instructions in the wiki and edit them if necessary.

Thanks man..
@pellmen i have a favor to ask you... this "panic with micron chip" we had earlier is bothering me... i've hoped I could track it down to a bug in my code (or somewhere) but it just doesn't make sense. I've seen the posts on 4pda, about how a custom pandorabox build worked, but that doesn't really make sense to me either (ie, needing to modify uboot seems strange).
looking at the bootlogs (https://4pda.ru/forum/index.php?showtopic=810698&view=findpost&p=82662335) and particularly the bit where it prints out the mtd partition table, it looks like they end the partition table at 0x00000f200000 while on my bits I end the partition table at 0x00000ff80000 ... I wonder if that's the trick to get it to work on Micron chips (ie, end the partition table early). (BTW, one "technical document" talks about reserving 2% of space for bad blocks... -2% of 256MB would end us around 0xfa00000 (which is still earlier than 0xf200000)...
so now for my "favor"... I really want to make "openwrt on mir3p" a success (i don't know if you can tell already)... and it irks me to know that users with micron chips won't be able to install my bits (at least it seems that way)... do you think "skull999666" (who reported the panic) or "toikvl" (apparently he also has a micron chip) would be able to help out (since I don't have one I can test with)...
what I'd like to see (perhaps most importantly) is the bootlog from "stock" xiaomi firmware booting the mir3p with a micron chip... I want to know where the mtd table ends on stock/micron... and if it ends somewhere different (like 0xf200000), if they would be willing to test custom bits? i got the official go-ahead to release two versions (for the ESMT chip and for the Micron chip) of openwrt/mir3p but I first want to see if I can figure out what's wrong.
I guess I could post to 4pda but I'm shy because I don't speak russian and i don't know anyone there.. but if you think it's best for me to post there directly, I'll do that.
