I tried this method but the issue still remains. The signal is weak, cannot connect to 4G even I can search it in manual network searching, 2G not found even in manual network searching.

I also tried to flash V300K firmware but it's no signal, sim card is recognized. Don't know what to do now :(

We have signal icon on status bar :p. I'm downloading V300K20e. Shall try to flash it ASAP.

Hi, I tried some H930, H933, US998, V300L roms on all Android 7, 8, 9. H933: weak signal, cannot connect to 2G or 4G network, but the icon on signal bar always show 4G even in about->network it shows HSPA. US998: same as H933 but the icon on signal bar shows 3G. H930: no signal. V300L: no...

I checked the hardware. It uses SD835 and has 4GB of RAM so I think it's a V30+. I checked the IMEI of my previous V30+ and imei.info also shows it as a V35. It's possible that the store sold me the refurbished phones with a fake IMEI. So, how can I find which is the rom can bring back the...

My phone is V30+ so I don't know if the page have any mistake with V30+ and V35 or it's a fake IMEI.

It does not show anything :(

Thank you for your answer but I cannot find the region info for my phone

hmm the Swappa page shows the result: No products match this ESN/IMEI. do you have any recommendation? I don't think that a rom flashing can make signal weak :(

Currently, it requires a paid account to check the info :(. Do you have any other website?

Sorry for my English. I will tell again my situation just to make clear: I got the phone from the store and it was running us99820b. Everything works fine 2G, 3G, 4G. Following the instruction, I used partition dl to downgrade to us99810d but it could not register to any network even the sim was...

I live in Vietnam. My phone was running us99820b when I bought it at store. I think both h933 and us998 support LTE band in my country. I tried to use partition dl or refurbish but my phone could not get any signal so I tried chiperase. I recovered the IMEI by Qualcomm NV Tool (I wrote the IMEI...

I went to the store and replaced my phone with another one which worked probably with LTE. I repeated the steps in method 1 and my phone get no signal again. I chose option ChipErase (already rewrote IMEI) and now it only works with HSPA. Is there anyway to fix this problem? Update: I found...

Update: My phone gets signal again after I flashed it to H933. Now I flashed it back to US998 and HSPA works fine but LTE or GSM. It cannot register to LTE or GSM network even the signal can be found in manually network selection.

Hello, I tried method 1 but my V30+ was stuck in LG logo so I used method 4 and my phone could be upgraded to Android Pie. However, my sim card cannot be registered with network even in phone status, it still shows my mobile phone number. I went to Mobile network settings and changed the...
