My issue and how I resolved it!
OK I thought I would share my experience to help anyone that may be running into a similar problem to mine, and how I fixed it.
I have a Wifi N7 (grouper) that updated itself to 5.1.1 (stock) a while back, and started running like a dog, so I thought time for a ROM.
I chose the 7.1.1 ROM from this thread as I was recommended it.
So, here's what I did first time round (which gave me problems):
- Using NRT, unlocked bootloader, and installed root/TWRP 3.0.2
- Placed 7.1.1 OTA, and dynamic gapps, onto internal storage
- Rebooted into TWRP, advanced wipe, wiped everything except internal storage.
- Installed the 7.1.1 OTA, then wiped Dalvik.
- I then rebooted and let it boot fully into android. THIS is where the problems started.
It booted straight to a home screen with a clock and a few icons. It didn't go through new device setup. I then rebooted into TWRP, and installed dynamic gapps. When I rebooted back into android, I started repeatedly getting a "Google Play Services keeps stopping" message, and nothing I did seemed to help, I tried all sorts of suggestions, such as clearing play services data, allowing all its permissions etc, nothing worked. So I had to start again and reflash the ROM.
Here's the procedure I did which worked fine:
- Rebooted into TWRP, advanced wipe, wiped everything except internal storage.
- Installed the 7.1.1 OTA, then wiped Dalvik.
- Rebooted, but immediately held pwr/vol- to get straight back into TWRP. **DON'T let it boot normally into android.!**
- Installed the dynamic gapps
- Rebooted again, this time letting it boot normally (1st boot will take a while)
- On boot, it enters setup and you can just take it from there (I always setup as new device, to avoid any possible issues)
Only thing I'm facing now is it seems to be charging rather slowly, my USB tester stick is showing the charge rate settles out at 0.6A which is quite low, it used to charge at more like 1.5A before. However this is a known issue with this ROM, so I'm sure a fix will come along. However I can confirm that disconnecting/reconnecting the charger as stated does seem to increase it a bit.
Anyway aside from that it seems to be running really well, nice and smooth, a darn sight better than the official 5.1.1 update which messed it right up! I expect Google won't be doing any more for this model either.
Thanks very much for all the hard work AndDiSa.!
Hope this helps
