Vemeni Good day to all! Problem in the following: Phone came from Israel. It was already sewn several local regional service multifile factory firmware. Prior to that he worked there normally - is unknown. Check was not possible and even if all the time buggy -It would be even noticeable that something is wrong. Maybe Simcoe and tested in the rapid version. The problem is very unstable in the 3G network mode. ie dial-up via the Internet through just once. In 2G mode - it works fine. Weed out such reasons as the symmetric map, the operator, technical konnektirovanie, a slot antenna, and so on. Could it affect anything except the modem? Communications chip hardware "non-native" (can be laid on the iron range stranger), section EFS? There is a problem that, after the original EFS there are troubles with communication (after flashing), but do not know whether it can affect only 3G? And if so how can it be solved? Was originally iOS 4.3, was stitched on 4.3. The problem did not go away. Stitched service 4.1.2 and updated over the air to 4.3. Then he flashed Single-4.3. There is a full backup for the TWRP after the first firmware 4.3 .IMEI in place as was originally. Can someone faced with the option? Backup EFS entirely original course not.
By the way exactly the same problem with the officially bought "vinfonoy" (certified) Nokia 620. The same solution has yet been found.

P.S. The reason is revealed. On the reverse side of the board is right in the middle of the antenna GSM biasing contact with the impact which structurally may prosest. On board a lot of contacts, and almost all from the front and this can and miss. Which is what happened. In this case, it touches but it was not a good contact. That's the whole reason 2 days troubleshooting. (Maybe someone will come in handy)

Welcome flies IMEI during the transition to any caste, keygen is not flies. Efs restored, with backup from 4.3 to CM13, imei appeared for a few seconds and then display the no service and nothing else helps, tried once again to restore the backup, sewed modems including and with patches and it was no. 4.3 All works, which way in the cap may come?

The answer is obvious - not to custom bikes. } -)

PS And if so you want - it turns addressing the author of custom bikes. : Yes2:
