[Android Q&A, Help & Troubleshooting] insomniacno1:
Hi to all, I recently bought a Cherry Mobile Fusion Bolt(rebranded Ainol Novo 7 Venus/Myth) here in the Philippines, and I have been having some issues with saving APN. Funny enough saving APN worked first time I used my Huawei E1552 Usb modem(after dissabling the cdrom and sd card), but after this I can't save APN and the list is empty. I read hundreds of pages on the net and here and tried most suggestions, with a few differences:

I'm on original ROM, and don't want to flash to another one,because this is the only problem I have, everything else is working.

I live in the Philippines and not SA or US. 4 months a year I live in Denmark.

First time I tried the modem were working with PPPwidget - but not after the new version came out, then I tried disabling the cdrom and SD card via putty on my pc,then the modem worked fine. I needed the cdrom in order to re-install drives on my pc so had to reset it to factory defaults, and when finished then again disabling the cdrom and SD card, and then the APN problem started.

I have downloaded allmost all PPP, UMTS, 3G, APN, System tuner, Tweakker, Toolbox, there is on the Play store and on the net and used market enabler when something was incompatible with my Tab. Nothing seem to be able to give me the APN back. It seems like the APN is locked somehow.

This is a rooted device, from manufacturer, only thing missing when I got it were SU, so I installed Superuser from ChainsDD, but later read that SuperSU fron Chainfire were better and uninstalled Superuser via Play store, then installed SuperSU and rebooted.

Android 4.1.1 JB Kernel 3.4.0+ Build number Cherry_A610_V2

1Ghz A9 Quadcore ATM7029 Cpu

GC1000 QuadCore Gpu

7" HD IPS 5pt. Capacitive touch panel WXGA 1280x800

Micro SD slot for card up to 32GB

8GB Nand Flash instead of 16GB

1GB Ram

Wifi

Micro USB 2.0

VGA front camera, 2MP back camera

Super HD 2160p

4000mAh battery

3G support through dongle

OTG but cable not supplied by Cherry Mobile(you can buy it in CDR-King for 60 pesos).

Cherry Mobile has NO support for this model on their homepage, funny since all their shops are out of stock with this model. I had to buy mine from a different shop. Ainol is even worse since their site is chinese only, can be used through Google translate, but then the search function doesn't work and you have to read through many pages and not finding anything.

When I start the Tab, attach the modem I get signal bar in notification, but "No internet connection", then I go to Mobile Networks> APN and its empty. Then I go to search for Operator and it finds Globe PH Prepaid, i chose that but nothing happens APN is still empty.

Then I try manually to set the APN, I just copy the info from my Samsung Galaxy Ace Plus, and then hit menu button to click the Save button, but this is were things go wrong - there is no save button, actually when I hit menu button, the screen changes to APN list and its still empty. I also tried to just hit the back button, same result.

I tried getting Tweakker from Play store, to automatically set the APN, but after the APN list is still empty.

I Tried APN backup & restore, backing up then restore, still empty. Doing the same thing then restart, stil empty. Removing all apps that had anything to do with APN or 3G modem and clear all data for them. Try above again, still empty.

Try my modem in my pc - works fine. Reset it again to factory defaults - works fine. Update firmware so I now also have phone and MMS - works fine. then disabling cdrom and SD card - try with PPP widget - not working. Then changing the dailup number, save, try dailing - hung. Then changing it back to the correct *99***1# - now working but still only browsing works. Ok decided to update PPPwidget to newest one - now not working. Switched back to old version I found on the net - still not working. Read on the the homepage of PPPwidget that the desired options I like besides browsing(TXT, MMS, Phone, Downloading from Play store) might not be available since the JB don't see the connection only some browsers do. OK uninstalled PPPWidget to try and get it set up manually like in the start, again not working.

Starting over from scratch(not resetting though - tried that on another "Chinese" tab and had chinese menues(ARRRGH)).

I'm back to the point that the APN list is still empty.

So my questions are simple:

Could it be that the list of the APN is locked somehow and thats why I can't add APN's?

Could it be that one of these wonderfull App's has deleted some system file?

Could it be that the APN list is read only, and only write for admin, where the Tablet thinks I'm not.

Could it be a general JB problem - I have read hundreds of similar stories on the net - all with different Tab's some with phones?

Any suggestions on what I can use - APN manager free is no longer available from Play store, and the Pro version is said to have major problems with JB.

Hope someone can help

With kind regards
