Hi recently I flashed a custom ROM and due some issues I came back to twrp flasheable stock rom 7.0 (latest on April security).
After flashing the stock rom I have found that my phone is not able to catch the signal . I thought my imei was broken but in system status imei was present and everything looks fine but showing no service and signal strength also nil.
I have tried various sim cards in my phone and none of them worked in catching signal. All of them showing no service and no signal at all.
Please help me if anyone know how to fix this issue, as I use this phone as daily basis.
I have restored my phones efs, persist backup but no use.
I am using Indian Variant Moto g5 plus...

Hey everyone. I have installed multiple custom ROMS on my phone including unofficial temasek and xperia cm 12.1 razor ROM and all of them end up with an exclamation point next to my cellular signal. Stock I have to issues with only custom ROMs. I made sure AT&T APN was correct and the preferred network was LTE. I know I have LTE signal because if I install stock it works fine. Any suggestions?
have you tried manually registering on att lte through cellular network setting?
No LTE after remote support from Oneplus Team
Guys,
I am new to this forum, so pardon if I made any mistake in posting.
Well, I have recently undergone a remote support session from oneplus team, during which I they have flashed my device with an special software (it was done to address broken fingerprint sensor repair). But unluckily I ended up with no LTE on my phone.
I was using same phone with network provide in the same area on LTE prior to that session, but later on my device no more work on LTE. Kindly help me resolving this issue.
I have tried putting my SIM in other phone, LTE works there, (other phone is Oneplus X, and in same area).
I have tried putting in other sim of same network but still no luck.
I have tried putting in a different network sim card in my phone and it works on LTE.
My understanding is, the the current ROM has locked the band which I was using earlier for LTE. Kindly advise.
Hi all,
I own a SM-A500M phone. The phone has unlocked stock rom (original rom is not modified by carrier) and updated trough OTA to android 5.0.2. I know 4g does work in my phone because I could use it with my prior carrier, but I recently changed to CLARO and with this new provider I don't have 4g acces, only H+ and it is really slow and laggy connection.
I know the following:
1) Sim card is a compatible 4g nano sim
2) The carrier CLARO has 4g coverage where I live
3) The phone is not the problem
4) I have tried all the usual FAQS (APN's, select LTE in config, reboot) with no success.
5) The phone's variant is right (latinoamerican brand), so It can't be due to frequencies or bands problems.
I asked for help in CLARO and told me that this has happened amongst users with unlocked phones (that is, rom not modified with CLARO's bloatware), and the solution is to flash CLARO's rom. But the problem with this solution is that CLARO hasn't released android 5.0.2 update (and I think it will never update) and I really like android 5 and wouldn't want to return to 4.4.
So, is it true? Is there a chance to fix this problem with minor tweaks? What is the problem here?
Since I recently acquired this phone, I would prefer not lossing warranty, so rooting and custom roms might not be an option.
Thanks in advance. Kind regards!
You could try to flash their rom and check if it works. Then you can be 100% sure that hardware/chip/network provider are fine. I have the same phone on since last week, but still did not go to get the chip at a movistar office. Maybe you need to activate the chip and they refuse to do it unless you get their rom. Maybe just getting their rom, and then flashing back the updated stock one or a CM or whatev would be enough.
Hi there, I would like to know if other people are having signal problems after the MM update. I am on Tmobile on a AT&T Unlocked Priv that WAS working perfect (signal strength wise) when it was on Lollipop. Since I upgraded by OTA to MM using a friends Simcard my signal is a mess. It cycle between LTE , 4G, 3G, EDGE all the way to GSM (G). And when I hit the road it stay in EDGE most of the time. That didn't happen in Lollipop and have never happened in my Nexus 6 and Nexus 6P. So is no TMO signal, is something that AT&T or Blackberry change on the modem firmware.
I tried to flash the old modem (lollipop) but it won't boot and told me the data was encrypted and corrupted and needed to wipe my phone. I flashed back the MM modem and booted. I flashed the TMo modem and I don't think it is sticked or maybe is it just the same one. Can you reply with your baseband numbers. Mine is MPSS.BO.2.6.2.c2-0007-M8994FAAAANAZM-1.55185.2
Any help will be very appreciated.
I had hardbreaked my moto g5 plus (XT1686) indian variant before.
Somehow i recovered my phone, and i installed Pixel experience ROM, but i lost VOLTE access..
I have a jio sim, there is 4G network but no VOLTE,
Is there any way to solve this problem????
Hi, Any Luck on this. I am also stuck on this issue. I tried stock nugat/oreo and pixel Experiance but no luck.
Did you try flashing stock twrp flashable builds? Probably your persist and efs got messed up. Maybe restoring stock could rebuild those and then you can flash PE. Make sure to boot up after flashing stock atleast once. Hope it helps. All the best mate
Hello. I have unlocked Verizon V20 VS995 and I am in Europe. In the urban areas phone works fine with all frequencies, also 4G B3 and B20 frequency, but when I go just outside town it looses network. Any sugestions?
CDMA LGV20 will suffer with those issues in Europe. So just switching to a native LTE/GSM device is the only way...
But I can't understand why the sognal is so weak when phone supports all the frequencies in my country. I even changed antennas (plastic bumpers) but still the same result.
Simple explanation - it is not a HW issue - the root cause is combination of your modem firmware and stock ROM you are using as the LTE/GSM band usage is set to be with lower priority and the modem constantly searches for the CDMA signal firstly...
So, is there anything to fix this? Maybe flash another rom or modem, if I find somehow to root stock Oreo.
If you are in VS995 really (and please check the sticker indication under your battery for that it should state VS995 only without Sat the end) you can roll back to Nougat via kdz flash and unlock the bootloader via DirtySanta, flash custom recovery and flash afterwards AOSP/LOS based roms.
I think I have VS995 because before ota upgrade to Oreo I have installed few KDZ's from the link without any problem. Can you tell me how can I check ARB version of Oreo?
All Verizon ROMS including Oreo are ARB00
Also you might try flashing Oreo Alpha Omega Hybrid ROM firstly and if not happy than try RR roms...
Tried Alpha Omega ans Lineage 15.1 and the situation is the same. Poor signal strenght.
