Xiaomi 4a R4ACV2 new version / bricked

rubydesign · July 27, 2023, 9:04am

Hi everyone
first a thanks to everyone who has participated in getting the 4a's (gig and 100) to work. They are great value and it is a joy to use safe/open software on them. I got about 10 of either working, it's great

In my latest order of 4a, there were some V2 of the 100m international version.
In fact i did not see that in time, the thing just bricked, but i saw it registers as MiWiFi-R4ACv2 on the dhcp. I checked onother V2, and uname does include the V2 version string.
After the brick i checked others and they register as MiWiFi-R4AC and also have that same string in uname -a

So i am wondering

did anyone else come across the V2 version and if so is there build
how can i get more information now that i have brick ( i am trying the debricking tomorrow)
if i do manage to debrick, how can i find pertinent info in the cmdline

I am not a hardware person, but happy to crack the thing open and take pictures. Or run commands on another hacked V2 device. I've seen talk of sku, but am not sure where to find that. But i can run commands on the device and post them.

Thanks for any help,
Torsten

That's probably where you should start. Take pictures in a bright environment, like e.g. outdoors, but try to avoid lens glare and e.g. the sun shining from any of the metal parts, and if you have trouble keeping the camera steady, use e.g. a cardboard box or something to support your hands so as to avoid blurry pictures. Try to cover every single portion of the PCB and take multiple pictures of slightly different angles if needed.

Thanks @WereCatf , i can do that, but it is a VERY similar. I mean it says 4a on the box n'all. Anything in specific you would be looking for?

But i can get in with the Invasion script, and since the "original" firmware is a cut OpenWrt, i can find out things in there. Like now i got the mtd

root@XiaoQiang:~# cat /proc/mtd
dev: size erasesize name
mtd0: 01000000 00010000 "ALL"
mtd1: 00020000 00010000 "Bootloader"
mtd2: 00010000 00010000 "NULL"
mtd3: 00010000 00010000 "Factory"
mtd4: 00010000 00010000 "crash"
mtd5: 00010000 00010000 "cfg_bak"
mtd6: 00100000 00010000 "overlay"
mtd7: 00c60000 00010000 "OS1"
mtd8: 00b00000 00010000 "rootfs"
mtd9: 00230000 00010000 "disk"
mtd10: 00010000 00010000 "Config"

Which is clearly different from the 4a version 1 (i'm just going to call it that, since now we have v2)
I will set up my compile environment, if you know how these changes relate to the menu?

I'll add the /proc/cpuinfo , but that is as much as i have read up on. Don't know how to find the wlan soc info i've read about.

Ok, pictures as good as my fairphone lets me (not super, but i can always take more if i would know what i am looking for)

First MediaTek is a bit small for the camera, says MT7613BEN 2246...
Second Mediatek chip was hidden under the metal shielding, says MT7628DAN 2252...

WereCatf · August 2, 2023, 6:10pm

I don't doubt that it is very similar. The whole point is whether it is identical or not. If I had to guess, there's probably no meaningful difference on the PCB other than perhaps the SPI flash being used, but still, I'd want to know.

I can take a look at the partition layout later, but I am just going to bed. I also don't have either the v1 or v2 myself, so I can't try anything myself -- I do accept donations, though, since we're talking about very cheap hardware.

WereCatf · August 2, 2023, 10:49pm

Looking at the big picture you took, there's the 8-pin SPI flash in the top-right corner next to the unpopulated 4-pin header. Try to get a picture of that as well. Can't see the markings on it in the big picture.

Please, also post full output of dmesg.

With that, it should be easy enough to squeeze out a firmware image for this new version.

rubydesign · August 3, 2023, 8:50am

Ok, that is too small for camera, having difficulty with a magnifying glass. Best i see is
Gigadevice 25Q128ESIG C012605 PH2216

I found the add new device page and was going to run al those commands and post the result.
Also got the compilation set up, so a .config file would do me? Though i didn't see anything in the options about boot layout (which i have yet to understand), so maybe a diff?

WereCatf · August 3, 2023, 10:21am

No, the device requires setting up a proper ramips target with custom DTS to get the partition layout correct. That's why I asked for the dmesg - output. I have already everything else set up, just need to know the physical layout.

Ok, got the dmsg.

I have now compiled a version of OpenWrt for the router that shouldn't brick it, but I do not guarantee that. If you flash it, you do it at your own risk. I hope you have a CH341a or similar lying around, so you can first take a backup of the SPI flash, so you can recover if you do get a brick. If you don't have one, you better buy one first.

https://www.dropbox.com/scl/fi/xvsdz07n694fi5uvdskgj/openwrt-snapshot-r23676-1-57fda4b743-ramips-mt76x8-xiaomi_mi-router-4a-100m-intl-v2.zip?rlkey=1d07x6fz6qguh4wtgccoy40k1&dl=1

I am not going to do a pull-request to upstream until it has been verified that my patch works, so until then, you can use https://github.com/WereCatf/openwrt/tree/r4aintl_v2 if you wish to compile the whole thing yourself.

All right, Kudos. We're off to the races.
It's not a brick, i can get in with luci and ssh, both wifi work and i can get 90Mbps through the ether-net port. If you want to know anything more, let me know.
All in all i'd say we have a winner, good teamwork. I do hope you can get that pushed upstream.
Should i try to change the wiki of the 4a? And how would a new device page come about?

We are a non- profit organisation, so we might have misunderstanding about the meaning of what you called "very cheap hardware". For us that is a great thing. I have to buy 50 devices for our very large house, with virtually no budget. So Xiaomi 4a was perfect, i even love the built in bandwidth control (only 100m port).
I'd be happy to buy you a coffee, or even better offer a stay at our place. We do have resident artists and digital nomads, where i can get you a discount, if you are one of those. https://residency.hubfeenix.fi/ (also www. ). Thank you.

I can handle updating the wiki. I just need to know if there's any good way of externally deducing if one has a V1 or V2, like e.g. do you see any clear difference in the sticker on the bottom? If not, then I suppose the best option is to get a root on the device and compare the partition layout reported by /proc/mtd, since it's different between V1 and V2.

As for my mention of cheap hardware, I didn't mean any negative connotation with it. Just its monetary value, nothing more. But yeah, I was doing 10 different things at the same time and my thoughts were all over the place, so I came out a tad incoherent. Feel free to just ignore that bit.

I did notice some mentions of the 5GHz WiFi possibly being unstable -- V2 uses different chipset than V1 for that -- but there's nothing I can do about that. That's a driver issue and has to be fixed in the driver itself. Just mentioning this in case you experience any issues. If not, all the better!

rubydesign · August 5, 2023, 8:06pm

All good, thanks for the help again.

Nothing from the outside that i can see, compared to the V1.

Since one has to do the OpenWRTInvasion anyway (and get root) the mtd is ok. But maybe the simplest way is uname -a and the V2 will have the string MiWiFi-R4ACv2 in there, while V1 will have MiWiFi-R4AC

Hi there! Thanks for your work! I confirm that this compilation does not brick the divice, which is an achivement for me already (since I have bricked it a couple of times already and had to debrick it with CH341a progammer)!!! However I really need firmware based on v21.02.7 feed. Please advice how should I aproach this task using your patch? and/or your github source?

I appologise in advance for dumb questions, as I am relativery new to OpenWRT. I am trying to learn how firmware builder works based on standard devices so far...

WereCatf · October 16, 2023, 4:20am

The patch with my changes won't apply cleanly as-is to an older feed as the files the changes would apply to aren't identical. That said, the commit at https://github.com/WereCatf/openwrt/commit/74dea277bbaac1870ee08855130be4b3f8b39fda shows the changes I made -- looking at specific commits on Github lets you view only the changes that were made in that commit, no other cruft --, so you basically have to go and inspect the existing files, look at the changes in the commit and then implement those changes, possibly modifying them a little to match the existing stuff. It shouldn't be particularly difficult, it's not like there are a lot of changes.

I can't hand-hold you through this process, though. I am currently struggling IRL and I just don't have the capacity to take on extra stuff. At least give it a burl yourself. You can always ask, if you stumble across an issue that you just can't figure out yourself (plus you'll learn the most this way, so it's more educational in the long run)

Since I am all for sharing knowledge, feel free to ask questions. I don't promise to get back to you in any timely manner, but I'll try to answer you when I have the time and/or I remember to.

Thanks for your work!
Is there a plan to add your patch to main openwrt tree? 4A Gigaibit v2 is already there.
