[Atrix 4G Q&A, Help & Troubleshooting] SERCASER1:
Hi everyone, i have just spent the whole day searching about this problem and i have not found solution, and things that worked for some people, won't work for me.

Hope you guys can help.

I'm going to tell you the events before i had this issue so you can get a lot of info about what posibbly happened:

1. I was tired of my phone being slow and some apps didn't worked for it because it had Android 2.2.2 Froyo and was never updated.

2. I decided to update installing Neutrino 2.9 by Notorius : Thread .

3. When i was trying to install the custom recovery i did something wrong and had to flash a Stock rom using RSDLite.

4. The rom that i installed was a Stock rom from Personal Argentina 2.3.6 Gingerbread.

5. After flashing this rom, the battery won't charge over 93% or something like that.

6. I wanted the phone to reach more battery % so i did something that read here at xda.

7. While the phone was off and charging, i removed the battery and once it showed the "?" symbol, i put back the battery, so it showed 5% and i panicked!!! because the tutorial said i had to install some zips from the recovery and when i tried to get into the recovery (i had already installed CMW) it didn't loaded the recovery. I pulled off the battery and try many times to get in the recovery but i couldn't so i powered on the phone an let it charge for hours but it didn't worked.

8. I was getting crazy so i tried to calm down and do some research here at xda, i was reading for hours until i found This thread , the guy said the the only thing that i had to do was waiting for the app to show approximately 4200mV and hit fix, it should fix the problem:

in my case, percentage shown was 8% and when i hit the fix, it raised 2 or 3 points (remember this numbers) i guess, but didn't fixed it at all (100%) so i started hitting fix every 10 minutes after being sure that the voltage was 4200 or above.

9. While doing this fix thing every while, i saw that every time it raised 3 or 2 points at the percentage shown, (the whole process was done with the phone plugged into the wall charger). I sttoped when the percentage shown was 97% because i was afraid it would cross to some 100%+ percentage, and 97% was nice for me.

10. After fixing the battery indicator issue, i decided to follow carefully a tutorial too install Neutrino rom 2.9 EE that i mentioned before.

11. The whole process was great and i successfully installed the Neutrino Rom i was happy and everything was fine.

12. When i was looking around the features of the new rom, the phone freezed and rebooted i thougt that maybe i was touching so many settings that it became unstable,although i didn't touch anything about processor speed , so i power on again and after a while another reboot , and another and another, i started to get mad at this and tried to find out what was causing this reboots.

13. Suddenly i had an idea and pulled off the microsd card, after this, the phone was like 9-10 hours without any rebooting and i was playing and installing several apps, and checking some tweets and facebook and everything was fine.

14 After like 11 hours since the last reboot, the phone rebooted again and this made me mad again.

15. I turned on the phone again and i saw it had like 40% of battery left, so i plugged it and let it for an hour, when i checked back the battery level, it was at 92%, so i let it for about half an hour more and it had again 92% of battery.

16. So i thougth, well during the flashing process the battery indicator got miscalibrated again, so... (pay attention to this) i run the app that fixed my problem at (see step 8 and 9 above) , it was at 92% and remember i saw that it "jumped" like 2 or 3% off battery shown, but instead, it jumped to 100% and battery shown jumped from 92% to 177% i panicked!! (again), and unplugged the phone.

17. I continued using the phone normally and before going to bed i plugged the phone.

18. After like 2 hours charging, i went to check the phone back and it was DEAD

So i tried this:

1. Plug the phone to the wall charger ---> RESULT: nothing happened.

2. Plug the phone to the wall charger without battery ---> RESULT: nothing happened.

3. Plug the phone to the PC via usb with battery ---> RESULT: green led turns on for 1 seconds and then goes off

4. Plug the phone to the PC via usb without battery ---> RESULT: green led turns on and stays turned on, until i put back the battery

5. Plug the phone to the wall charger (samsung galaxy s3 1mA) ---> RESULT: nothing happened.

6. Plug the phone to the wall charger without battery (samsung galaxy s3 1mA) ---> RESULT: nothing happened.

I hope some of you can help with this, i've read a lot of posts but they are from 2011 or 2012, i'm making this one because non of those gave any help. Thank you very much for your atenttion.
