Hi KilgoreT

First, thanks for your patience and help :)

I put the SP Flash tools in folder C:\nobackup\Chuwi\ and extracted there the archives (it created subfolders of type C:\nobackup\Chuwi\SP_Flash_Tool_v5.1916_Win)

ROMs were in a subfolder of the same location: C:\nobackup\Chuwi\ROM\ and extracting them created folders like c:\nobackup\Chuwi\ROM\CHUWI_Hi9Pro_backup_orig_O00623 release-keys OGS 20181226 (same archive name like the one you mentioned, I triple checked it and download it several time).

I did not change the location of any file after extracting, as I assumed that they need to be in same folder.

The SPFlash was in a different location as the ROM (e.g. I did not copied the files of SPFlash and ROM into same directory) as this was not mentioned anywhere so I doubt it would help.

I have attached also a screenshot from a video done during patching that was saying Download OK at the end, you can see the paths of the tool and the ROM (the files below were properly detected with their path and loaded during the patching).

I will try tonight the Format All, start tablet (should have no OS), then move the files to simpler folders names like C:\SPFlash and C:\ROM (without the versions etc) so to eliminate that as an issue.

I orderer my tablet on October 31 2018 on gearbest, the description said Chuwi Hi9 Pro CWI548 4G Phablet, Black, CPU: Helio X20

I then saw that they had the same with CPU Helios X23 for 2 USD more, so I contacted them and they said they can change it and sent me the invoice to pay.

I payed on Nov 1st the difference, they confirmed the change of the phablet to CPU Helio X23 and then sent it to me

The link on Gearbest of the phablet is:

Funny thing is that the X20 costs 183 EUR now and the X23 costs 137 EUR ... maybe is the weird one the X23 :)

I tried after receiving it to check the CPU model with some apps like CPU Identifier or CPU-Z but it was not really showing X23 ... more pointing towards X27 ... but not a clear CPU identification was possible I would say.

I monitored this thread from begining and when I saw the different issues that were encountered during rooting and after during update, I decided not to modify the tablet and wait for a stable ROM. I thus refused the update of the tablet itself when it poped up, and continued using it with the 20180801 ROM that came with it.

On May 17 coming back after a long vacation the tablet was discharged, so I plugged it to charge it and started it while it was charging I think. It was workign at that time, but after several hours on charging I think it try to do the update itself and restarted as when I picked it up it was simply not working. If the table prompted a message of type: "update will be installed in 60s, click cancel to abort" like my IT department does sometimes on the laptop, I did not see it and did not cancel it.

I used my tablet mainly for business trips to watch movies / TV series, as surprisingly playing movies is very smooth on it (nice screen too) compared to browsing the internet on Google Chrome which I found very sluggish given the specs of the tablet (here I might get some remarks of type: if you want quality, buy an top tablet for top money, which I will just ignore :) )

That is the full story of my Chuwi Tablet :) not sure it can bring some light into this weird issue (I have to mention again that I never tried flashing it or root it before it simply "lost" touch screen calibration).

I also tried to create an account on the Chuwi forum site to report the problem to them, but I think they simply are ignoring users creations now (many problems reported?) as I got no reply and even wrote to a guy named Jeff to help activate my account ... no answer ... I think you were mentioning earlier you wrote to everyone except the president of China, maybe I should do that :D
