I currently Americanize qins for people who reach out to me from time to time for $30. I’m moving on from it now. If anyone is interested in taking this over, I’d be happy to refer the people who contact me. No commission or referral fee.
What do you do to Americanize qins.
Trade secrets probably 
Do you buy the phones for the people then sell it to them. Or do they buy the phone and you Americanize it for them. I enjoy working with phones and computers, but I don’t know anything about Americanizing phones. I would like to learn.
Start here
You should probably define more about the job
Just flashing bands? Custom rom?
I would do it if I had my laptop in yeshiva 
Install termux in a rooted phone with USB OTG available. No laptop necessary 
I actually flashed many many phones from my phone. Including flashing with mtk etc. Sn write tool not but I’m sure there are alternatives.
Btw anyone in this forum with an Android phone with apps (app installation not blocked) without termux…
echo "I'm really dumb now." && apt install termux && echo "becoming smart now..."
echo "I'm really dumb now." && apt install claude && echo "becoming smart now..."
I have a f21
Does it support usb otg? I would assume not
And it would probably be super slow no?
others here would probably know better about the f21 but last I checked I think it does. Regarding speed, not too much worse then on a laptop. By me it works perfectly on the f25
