UG007B Clockworkmod Issue



I eventually resolved this problem by flashing the original firmware. I now have hideous wifi problems, but the CWM installation procedure now works. Apparently the "stock" firmware on my device was not the stock firmware from Ugoos. Anyone running into similar problems may want to try the same thing (firmware, drivers, and flasher are in a download from Ugoos' website), although it'd be nice to backup your system with another tool first (since I no longer have any way to get whatever firmware I started with).



I got a UG007B this Christmas, which doesn't have a dedicated subforum here but which is one of the RK3188 devices. I would like to get into android development (though I'm a total newbie at the subject--I've rooted and flashed phones before, but not created my own roms etc.) with this device, but before I try anything I think it's a good idea to get CWM set up so that I can make backups. However, upon following the PC-less instructions here ( and flashing the appropriate CWM image, I find I get some hideous errors and am unable to make backups. I'm trying to track down the source of the problem to fix it, but I'm not sure how likely I am to succeed so I'm hoping someone here might understand what's going on and let me know what I need to do!

I am able to boot into CWM just fine. However this error shows at the bottom of the screen:

Can't find misc
Can't mount /cache/recovery/command
Can't find misc
Can't mount /cache/recovery/log
Can't open /cache/recovery/log
Can't mount /cache/recovery/last_log
Can't open /cache/recovery/last_log
Can't find misc

When I try to create a backup on my external sdcard I get the following:

SDCard space free: 7576MB
Backing up boot image...
Error while backing up boot image!

Although it DOES create an empty backup folder on the sdcard, so it seems to be able to mount that just fine. Upon going into /cache/recovery in a terminal and listing all contents, I find that it contains only two apparently empty files: last_install and last_log. This is the same as on a phone I have on which CWM works, so I don't think it's a problem with that; it seems to me that most likely CWM is having a problem mounting the filesystem disk in the first place--perhaps a mismatch between whatever CWM's equivalent of linux's fstab is on the image I installed and the configuration of my device. But I know nothing whatsoever about the internal workings of CWM or related subjects; it remains a sort of black box to me. So this is just a guess.

Does anyone have any idea what may be the problem, and what steps I might take to figure out the issue and resolve it? I'd really like to be able to start playing around with ROMS and maybe try and get ubuntu installed, but I don't want to touch anything until I can make backups (and I doubt cwm could flash a ROM in this broken state anyway).

Thanks very much for your time!
