    Pipo s1 turns on but freezes on boot screen

    I've been reading through others users problems relating to this and still I'm at a loss as I've tried most things other than shorting the nand pins out and re-flashing in masked mode.


    Had the tablet for nearly a year and been really happy with it, fast smooth and better than a nexus 7 using the free boot loader changer off play, however a week ago I switched it on and it said that the memory was corrupt and after shutting down and restarting I was left with just the boot loop problem, so I looked around the WWW for advice and found what was needed IE: the stock firmware unrooted English version (20130325).img , I could always root if I wanted to myself no problems there, and the batch tool.


    To be on the safe side I plugged in the power and - volume button couple mins followed by both -/+ vol together with power to get into the androids system for wipe and reset including caches. Tried this first, followed by reboot ...no luck was still left with it freezing and the screen was showing the pipo logo but there was no animation and at the bottom there were coloured horizontal lines a couple cm apart.



    Next I moved onto to re-flashing Not!! upgrading.


    Put the pipo in flash mode and checked that everything was ready in the batch tool, had to switch from pink to green and then proceeded to restore, Success!! no errors waited a few mins and my tablet restarted.


    All looked well, it was asking me to add apps. But like a PC install I waited a while and then shut it down so as to gather itself before adding anything, now here was the burn....


    Just as before, it had froze after being restarted on the pipo screen.

    Now if it were a black screen I would have thought about opening and cutting the battery supply for a few seconds, but this? I'm at a loss.

    I would really appreciate some feedback, advice, help ...yes I'm starting to sound a little desperate, but I don't know what else I am supposed to do.

    Cheers in advance.

    If the tablet was running fine for over a year and all of a sudden you started having problems...it sounds to me like a hardware failure somewhere.

    NAND chips do go bad.

    Instead of cutting the battery wire...just press the reset button (a little hole on the back) with a paper clip.

    The steps you took were the correct ones.

    Try repeating them. Next time go into settings and do a factory reset.

      Thanks for your observations, I must admit to have had a sneaking feeling that this may be the culprit in all this, soo..I'm left some tech to basically pull apart and sell bit by bit, ppl always need screens tried as you suggested and still, nowt, so it would look as though its buggered. Although I'm going to experiment and try loading up some of the roms I've thought about trying but never really had the balls to lol for fear of messing up my tablet.
      If I have any further success in getting it working I'll post up a tutorial for others whom may come this way.

        It seems to be working - Possible solution

        After yesterday I spent some considerable time weighing up my options, there weren't that many so I dug out some of the stuff I had recently downloaded and started flashing with various roms, waste o'time that was, then I used a folder which I came across which suggested pipo repair, basically it was the RKAndroidTool with a rom , kernel, misc and recovery included.

        Started RKBatchTool then RKAndroidTool and placed pipo s1 into flash mode, and ran the repair from the batchtool although first I erased the nand (idb) 2-3 times

        Pipo rebooted and still a non starter, so next I repeated erasing the nand using the RKBatchTool a couple of times and then proceeded to load the Chinese stock firmware everything went through fine and the pipo restarted, left it for a while, changed the language, switched it off, back on again and seems to be stable for the moment.

        It could be the repair or the cleaning of the nand, maybe just rom, either way I've gone from something I was going to breakup and sell to a working tablet again. So folks never give up hope if yours has balls up.
