OTGW not working after upgrade failed

[xvisor]

Hi,

Today i wanted to update my Gateway with 5.8 firmware. The last version I was running was version 5.3 and there were some fixes that it wanted. I have always been able to update trought otmonitor. But this time it was quite slow on programming and at 91% is stopped, there was 1 retry and 0 errors. But after a hour or so it was still on 91%. When i looked at the device the red, green and orange lights were on and the second green was rapidly blinking. So i logged in to my espeasy nodemcu and turning serial logging on which keeps showing me only a few letters like this:

547010 : Ser2N: S>: he
547027 : Ser2N: S>: «rm
547043 : Ser2N: S>: T
547056 : Ser2N: S>: h
547085 : Ser2N: S>: T
547087 : Ser2N: S>: h
547101 : Ser2N: S>: e«
547115 : Ser2N: S>: r
547130 : Ser2N: S>: T
547149 : Ser2N: S>: he«rm

Anyway to fix this? I don't have a pic programmer.

Well I've got it fixed... After retrying the firmware upgrade more then 100 times with the reset manually method everytime trying to do the reset a little longer or quicker (shorting the jumper). I thought the PIC was broken but after searching long enough multiple topics said it should still be flashable if there are lights so after a while I kept trying even more to no avail, either way I ordered the pre-flashed 16F1847. But I was so anoyed I tried it even more and anoyed as I was I resetted like 10 times quickly after each other and then the lights didn't blink anymore and when I looked at the screen is was flashing the bootloader after waiting 10 minutes it was finished. But still nothing, so another reset and there the green blinking light was back and my otgw running again... still don't understand and I am gonna replace the 16F88 anyway when it arrives. But for now it's working again.

It shouldn't be that hard. I have purposely messed up a PIC a number of times to test the recover functionality. Every time it only took a single reset to get a new upgrade to complete. In fact, I'm surprised that you had success with multiple resets. I would expect that a repeated reset would interrupt the upgrade, rather than help it to start. Also, 10 minutes is a very long time for a firmware upgrade. It should only take 30 seconds or so.
