EDITThe below is crossed out for a reason, you will probably have more success using UART to glitch out the recovery sequence and having it fail-open the UART input if you have a telnet locked AX3200/RB01. See: Adding OpenWrt support for Xiaomi "Redmi Router AX6S"/"Xiaomi Router AX3200" - #513 by arch_pilot

Presumably this device will be of little interest to those who managed to acquire cheap E8450/RT3200, but this should be available globally (well, if you count grey-imports from Ali as global) for a non-ridiculous price.

Around 70 EUR incl. 19% would be pretty reasonable, especially considering the scarce availability of the rt3200. The big question would be about how locked down (secure boot, etc.) this device is and how many other hurdles come up, RAM could be a tad bigget though.2

Even stranger, it appears their version of ddns-scripts is too old to have the commit that would have sanitized out the shell escapes for them? Or rather, they have the version number of a release that should have some checking, but the actual content of that particular commit isn't present? I think they messed up the merge when they forked their own one to add chinese DDNS services?

Forgive my ignorance - how are you seeing the contents of those files? Are you like decompressing the Xiaomi firmware images, accessing them locally on the device, or are you looking at their code repositories directly?

Not a very efficient layout. Obvious change would be to just merge overlay and obr like on the other Xiaomi device ports. Doing more would probably require some u-boot finesse or replacement like the E8450.

It turned out that Xiaomi divided the Chinese version from the global one at the level of firmware and the name of the "hardware".

The internal name of the global model is RB01, and the Chinese name is RB03. Previously, such a division was simply at the level of the region specified in the Nvram/BData partition.

Oddly enough, Xiaomi are advertising the MT7622B CPU as a FiLogic800, the only place on the internet where anyone is calling it such? I've edited the thread title as such, and added the "Xiaomi Router AX3200" as a variant. (Does this make the global version name the Xiaomi Xiaomi Router AX3200 in OpenWrt? That sounds weird.)

xiaomi-router-ax3200 - Specifications - Xiaomi Router AX3200 offers both 2.4GHz and 5GHz,Have a combined theoretical wireless speed of 3202Mbps maximum,Enjoy ultra-fast Internet access,Stable signal coverage and large-scale online gaming.

so mine arrived. it turned out that telnet is enabled in my router by default. password for root can be genrated using script from this page.

overall what are the chances to get working openwrt on this router?

I tried telnet once or twice when trying to get in without success, I suspect that the factory defaults in nvram/uboot-env are looser than usual for qualification tests or something, then are set back to zero on first boot. I recall similar things being mentioned on the Redmi AC2100.

Highly recommend you take this chance to telnet in and nvram set telnet_en=1, nvram set uart_en=1, nvram set ssh_en=1 (well, you'd still have to modify the init script to ignore the fact that you're running release channel firmware, but the contents of mine would reset on each boot so I think you'd have to put it in the overlay somehow), nvram set boot_wait=on, nvram commit etc; before you lose access. (Worst case scenario you would have serial access to u-boot with these all on.)

Yeah, I slightly modified the python implementation that was floating around because it had some weird dependency and expected a file, even though punching in the serial from the sticker/web ui was fine. I'll paste it below for reference, since many would prefer a python implementation.

Most likely you have factory mode activated. It is in this mode that devices are flashing. And it is in this mode that the telnet is forcibly turned on.

To check the activated factory mode, run the following query: -bin/luci/api/xqsystem/fac_info

Redmi is a subsidiary brand, which owned by the Chinese electronics company Xiaomi. It was first announced in July 2013 as a budget smartphone line,[1] and became a separate sub-brand of Xiaomi in 2019, to takeover entry-level and mid-range devices originally produced by Xiaomi brand, while Xiaomi itself produces upper-range and flagship Xiaomi (formerly Mi) phones.

The most significant difference from other Xiaomi smartphones is that Redmi uses less expensive components, allowing lower prices while retaining more advanced specifications. In August 2014, The Wall Street Journal reported that in the second quarter of the 2014 fiscal year, Xiaomi had a smartphone market share of 14% in China;[2] Redmi sales were attributed as a contributing factor toward this ranking.[2]

The first Redmi phone Redmi (Red Rice in Mandarin), released in China in 2013, was first launched on Xiaomi's website, with consumer sales beginning on 12 July 2013. The phone was internationally released under the Redmi brand in early 2014.[3][4]

On 13 March 2014, Redmi announced that their phones had been sold out in Singapore alone, eight minutes[5] after being made available to buy on Xiaomi's website. Criticism regarding the release of Redmi phones included the notion that the firm may be exaggerating its sales by releasing them in small batches, causing them to quickly sell out.[6]

On 4 August, The Wall Street Journal reported that in China's smartphone market, Xiaomi overtook Samsung in the second quarter of the 2014 fiscal year with a 14% market share in smartphone shipment rankings, while Samsung had a 12% market share during this time.[7] Yulong and Lenovo both had a 12% market share during this time.[2] Redmi sales were attributed as contributing to Xiaomi's increased shipment rankings in the smartphone market.[2] Conversely, in the first quarter of 2014, Xiaomi held a 10.7% market share.[2]

The Redmi Note 3 launched on 24 November 2015; unlike its predecessor, it does not have a user-changeable battery or microSD slot.

The Snapdragon variant of the phone, released later the same year, is based on the Snapdragon 650 and has microSD support.

In January 2017, the Xiaomi Redmi Note 4x based on Qualcomm Snapdragon 625 Chipset became the company's first major launch of 2017.[9] It is an upgraded version of the previously released Redmi Note 4 based on the MediaTek Helio X20 chipset. The device is known as Redmi Note 4 in regions where the original Redmi Note 4 was not released.

In September, Xiaomi unveiled the Redmi Note 6 Pro. It is the first phone in the Redmi series with four cameras (two cameras on the front and two cameras on the back) and constructed using 6000 series aluminium.

On 10 January 2019, Redmi unveiled the Redmi Note 7 and Note 7 Pro, the first phones in the Redmi series with a 48-megapixel rear camera. The Note 7 has a Samsung GM1 image sensor, and the Note 7 Pro has a Sony IMX586 48 MP image sensor. The Note 7 is powered by the Qualcomm Snapdragon 660 Octa-Core Processor clocked at 2.2 GHz, and the Note 7 Pro has an 11 nm Qualcomm Snapdragon 675 Octa-Core Processor clocked at 2.0 GHz. The Note 7 is available with 3 GB RAM with 32 GB storage, 4 GB RAM with 64 GB storage and 6 GB RAM with 64 GB storage. It has a 4,000 mAh battery with Quick Charge 4.0.[10] The Redmi Note 7 series of smartphones is one of the best-selling Redmi phones; over 20 million devices were sold in the 7 months from their introduction.

The Redmi K20 and K20 Pro (also marketed as the Mi 9T) are Redmi's first foray into the flagship market. The phone was launched along with the Redmi 7A in China on 28 May. The K20 Pro is powered by the flagship Snapdragon 855 processor while the K20 is powered by the newly released Snapdragon 730 and Redmi 7A is a less expensive phone with Snapdragon 439. Redmi Note 8 and Note 8 Pro were launched on 29 August, and Redmi 8 and 8A were announced in October 2019.

After emerging as a sub-brand of Xiaomi, Redmi employed the same Smartphone & AIoT dual core strategy as Xiaomi, and branched out to different product categories such as smart TVs, notebook PCs. Xiaomi also forayed into home appliances such as washing machine, and products such as luggage.

On 7 January, Redmi unveiled the Redmi K30 5G, it being Redmi's first 5G handset available in the market. The K30 is powered by the flagship Snapdragon 765G, an Octa-Core Processor clocked at 2.4 GHz. The K30 features a LCD display punchhole camera cutout with 120 Hz refresh rate.
