hello all,
after my tornado fel into the water i have a major problem.
sometimes i cant call, and when i try to call i only hear 2 soft "beebs"
sometimes when i am able to call it automaticly breaks the connection and again i hear the same 2 "beebs".
also sometimes people cant call me, but the screen says i have an connection.
i already put a new rom on the phone but it doesn't help so i ques it is a hardware problem.
I have another tornado for spare parst, does anyone know what this is?
maybe the antenna?
thanks in advance
It may be an antenna, but not for sure. You can try to disassemble Tornado and clean antenna connectors with any pure alcohol. If it doesn't help, it's PBA problem.
First you should have disassembled it completely and let it dry in all parts before using it again. Depending on how long it was in the water this may take some time. Taking fabric cloth and pressurized air can get it dry in a few minutes, but only if taken apart. Take care to remove the metal lids on the PBA as well and look inside for moisture.
There are no parts inside that take permanent damage from water if the device is without battery, but if it was on - end even used wet inside - then your prospects are variable. I would guess nevertheless that it should work again after all has dried.
thanks guys for the reply's,
i forgot to say that the phone felt into the water 1,5 moth before i started this topic. and 1 disambled the phone serveral times to make sure it was dry.
so inside it is dry now, but i tryed to use the phone with battery even when it was wet inside, so maybe that its where it went wrong.
what is the PBA? and where can i find the antenna connectors?
i already removed that metal box, and the chips underneath looks verry good. no corosion or what ever.
If you took everything apart already, then you should have seen the antenna connectors. The Antenna is located in the top cover at the back (above the battery cover). It connects via the two spring supported contacts on the upper part of the PBA (Printed Board Assembly). Both parts are gold plated, so it should not be a problem there.
Regarding the metal lids, take care to remove all of these (3). They are located underneath the keyboard (with the OMAP processor, RAM and the M-Systems DiscOnChip) on the same side of the PBA for the Radio and underneath the LCD.
As some chips are BGA soldered (soldered from underneath; BGA = Ball Grid Array), take care to blow with air also underneath (between PBA and CHIP). There is a very tiny gap between these and water hidden there may not dry for along time (if it has reached the area anyway).
However, the 2 soft beeps usually indicate that there is no free channel for you to be served (as far I remember) - you would get this problem with any other handset as well (same SIM assumed). It is a highly temporary problem (just retry) and you will not get evidence if you swap the SIM to another handset and retry there - network capacity has changed in the meantime and you would get a connection with the tornado as well.
If you experience call drops or other different behavior (compared to earlier) it may as well be attributed to a HW problem with the radio part in your device.
at this moment i use my htc hurricane with the same SIM card and i dont have any problems anymore.
so it is really a problem inside the phone. i havent used the tornado for 2 months now because it gets really anoying after a while.
i will take it apart for an another time, an blow some air underneath the chips as you say.
another symptom what i had was that sometimes the GPS connection was disconnected, and that the phone was searching for a signal for a long time.
but when i puted the sim card in my hurricane i dind't had any problems with the signal.
thanks again.
I have an inspire running coredroid v8.1 and I cannot get a gps lock at all, even if I let it sit outside for 10 minutes...
I have reflashed the rom several times, and even tried the newest versions of virtuosity and cm
I have followed the video to pull the phone apart and I'm positive the gold pins are making connection
I have tried angel death's patch
I have ran gps status and cleared and re-downloaded in a-gps settings, ran gps test, and ran faster fix
I have tried the trick where you pull the sim out and get a lock (I still get no lock even with no sim)
I've looked everywhere and tried to do all the research before posting a new thread, but I just can't find anything else and I don't know what my problem is...
any insight would be greatly appreciated
EDIT: Also thought I should include that I have flashed radios 12.41.60.19_26.06.04.14_M, 12.54.60.25_26.09.04.11_M2, and 12.62.60.27_26.13.04.19_M with none making a difference
Sorry to tell you but you might just have a bad thing piece of harware. I started a thread a little while ago called "GPS Last Resort". I tried everything... And I mean Everything! I was told that there were "known" hardware issues with the Inspire. So I un-rooted and returned to a "stock" state and went through the PITA process of getting a replacement.
Once I got my replacement, it was a night and day difference. My new one locks in less than 15 seconds with 5-4 meters accuracy.
Don't drive yourself crazy. If it is still under warranty, get it replaced.
Sent from my Inspire 4G using xda premium
did your phone have any other signs of being defective or was it just the gps? I mean, the phone is great except for this! No boot loops, force closes, glitches, or anything...
Also, if it's just the antenna, could I buy an inspire with like a broke screen or something off ebay and just switch them out? Do you think that's a viable option?
Sorry it took so long to get back to you on this...
You may not even need to replace the antenna at all. When you pop off the cover for the LED camera flash (this is also your gps antenna) there are two little spring like clips that are the contacts for the antenna. If those contacts are not making a good connection - your phone will just keep searching for signal. If you are brave enough - you can pop out the antenna and carefully bend out those contact clips in order to make a better connection.
I was hesitant to do this myself - and sense the phone was still under warranty, I got a replacement.
Sorry again for the delay - hope that helps if you have not already found an answer.

Yea be careful with this. I decided I'd go ahead and pop off the camera cover to readjust my gps antennae contacts and ended up breaking the cover. ~2cm crack just under the flash, which raises up the cover enough that the contacts won't make contact at all unless I'm applying pressure that only Thor could exert on the cover.
side note - 2 weeks after I did this my screen shattered.
Haven't been having much luck lately..

Ouch!
That is pretty much why I decided to go for doing the warranty replacement
I did the warranty after trying to remove the gps antenna because it still didnt work after i did that. The sent it back working !!!
Hello. i have a question. I have a problem with my mate 8. It's that that my GPS is not working (i don't get a GPS fix). I've sent my phone to the repair shop with guarantee, but they refused to fix it couse i have 2 slight dents in housing and apparently that is what is couses the GPS problem. (one dent is in area of volume buttons and the other is where the charging port is). It's really the dents that can couse this, or is the GPS itself? I could probably change the housing myself (they want me to pay 110€ for replacing it), but how is with replacing the GPS module itself? is it even possible? thank you in advance
its called an SoC (system on a chip) for a good reason, namely that the whole system is built into one chip or the same motherboard. so ud basically have to exchange the whole mobo ^^ maybe its just a bad gps antenna contact though...how did u get those dents?
Sent from my Huawei Mate 8 NXT-AL10
Ok, that sucks actually then
Is it possible to figure out if the gps is bad without changing the housing first? I tried AndoiTS GPS TEST and i get AGPS in orange. Does that mean that module is fine? (I added a screenshot).
Oh, and I've got the dents whit dropping my phone -.-
And another question. Where is the actual antenna? Or is the whole housing that works as antenna?
Hi. I bought the phone on the 8th October 2016. GPS was fully working. On the 10th, I updated as there is an update showing on my phone. After the update. I cannot get any GPS signal at all. This is a bad update.
Flash
I had same issue after I incorporated the KANGvip tools into AL10369 , just flash the cyst from another ROM like b200 or similar. If you don't know how then flash ROM to a working Rom with GPS. Extract the custom backup from twprp. Reload the nonworking ROM and flash only cyst and boom cops can find u after via gps lol

thanx to finding this thread i kept on searching
i recently changed the screen on my phone and since gps failed completely (wifi also seemed to be lesser)
as the phone lays on the screen, the copper nipple in top left corner is the contact the gps antenna has to make with the case.
i placed some paper beneath the element holding this niple, thus pushing it up - BINGO
i get a 3d fix in no time like before
also wifi connection improved
Where is this nipple? https://d3nevzfk7ii3be.cloudfront.net/igi/BPviD4orcNjWNIdi

Mate 8 GPS fixed !
Finally, after weeks of researches & tests I found the "nipple" or copper pin !!!
It's indeed the one on the top left once the screen is on the table. Either you find a way to put it back in position... without breaking it (the best way is probably with your nail) or you just put some Aluminium (a tiny sheet of aluminum folded several times to get 1mn maxi alu to allow the final winding) in the rectangular "hole" on top right (opposite) of the metal cover of MATE8.
I discovered the "right pin" while testing to put a small aluminium foil on several places of the main board (once opened naturally) AND using GPS TOOLS (playstore) ! you have to wait several seconds to get the signal or at least orange dots on the "radar". Better to test first such tool first with a smartphone where the GPS is working fine and compare both phones while changing the place of the aluminium. Nevertheless, I hope you would not have to repeat my tests as I will clearly show the right "copper pin" in an attached picture ...
Hoping that helps.

Hi!
If you are reading this now, you are probably one of the unlucky fellows who's WiFi (and Bluetooth) stopped functioning, and if so, you are probably deperately searching for a solution/fix. I might have something for you, but first:
*** DISCLAIMER/WARNING ***
You yourself are exclusively responsible for whatever may (or may not) happen to your mobile device, to yourself or others. I am only giving hints/advices here that *MAY* help, but I will not take any responsability, nor will I provide any support, in absolutely *ANY CASE*, including, but not limited to: your problem not being solved or/and your mobile device becoming partially or completely broken. Let me be very clear: If you do anything to your device rendering it useless, destroying it, seriously or fataly injuring you or others, and then come blaming me or/and cry for help, I will point my index finger at you and laugh at you. Period.
If you are a impatient person and want to get straight to the point, jump right to section 6.

0. Foreword
Two or three months ago, one fine morning, the WiFi/BT of my LG G2 suddenly stopped working. Initially I thought this would be only one stupid annoying minor thingy, that I’d be able to solve it fast. I was wrong.
1. Description of the problem
When turning on the WiFi, it would just stay in "Turning on..." forever. Similar thing for Bluetooth: It would stay on for a few seconds and then turn itself off again after. (But then, who needs Bluetooth anyway, WiFi ist probably 100 times more important...). I have thoroughly searched the internet, and I found quite some videos with exactly the same problem (remove the two blanks from the links to watch):

h ttps://w ww.youtube.com/watch?v=4W8YJMDFM88
h ttp://w ww.dailymotion.com/video/x2cuyjt_nexus-5-turning-wifi-on-frozen-problem_tech
2. Urgent advice
I want to prevent you from wasting countless hours searching for a solution - I wasted so much of my time already, no need for you to repeat that. Therefore: *Please* be aware that there is a VERY HIGH PROBABILITY that this issue is being caused by a hardware defect. I can not speak for all devices of course, but keep in mind that the main reason I wasted so much time, was me beliving it was some software issue! See the next section for a glimpse of stuff I have tried without any success:
3. Things that *DIDN'T* work
01. Restarting WiFi/Bluetooth several times
02. Rebooting the phone
03. Turning airplane mode on/off several times
04. Slapping/hitting the phone (this was indeed suggested in a forum)
05. Using WiFi-Fixer apps
06. Resetting to factory settings
07. Upgrading to newest Android version
08. Fully drained the battery and left it uncharged for several hours
(Rooted the phone)
09. Deleting the /data/misc/wifi/wpa_supplicant.conf
10. Deleting the whole /data/misc/wifi folder
11. Creating a file named ".bdaddr" in /persist/bluetooth containing a MAC-Address in hexadecimal format
12. Creating a file named ".macaddr" in /persist/wifi containing a MAC-Address in hexadecimal format
13. Flashing several custom ROMs to it (CyanogenMod, ParanoidAndroid, ...)
14. Going back to stock ROM
15. etc. etc. etc.
16. Several combinations and permutations of the above
4. There is little hope
Again, as the cause of the problem is most likely a hardware issue, I don't recommend going through all the steps as described in the previous section; however, though none of the steps worked for me, this doesn't mean that none won't work for you neither; you might be luckier than I was. In that case, enjoy your restored WiFi and be happy.
5. My most obvious advice
You need to replace the motherboard (main board) of your device.
Honestly, if you can afford it and it doesn't cause too many inconveniences to you, you'll be better off by simply buying a new device. If you don't want to buy a new device, send it in for repairs. If you don't want to do that as well, you'll have to fallback to a DIY solution:
I. Buy a new main board for your device. Be careful to get exactly the right component for your specific model. If you dont find any shop selling those, there are plenty of individuals out there that own devices with broken displays. You dont need the displays, you need the motherboard. Buy one such broken device, and you'll have your main board replacement.
II. Replace your main board or let someone else do it for you
Continues below.
continuation
6. LET'S GET SERIOUS!
If you are reading this, you either didn't read or you decided not to follow my most obvious advice in section 5. So be it. If you want to carry on from here, be sure to re-read my disclaimer at the top of my post.
There are 3 DIY possible fixes for the WiFi problem - none is guaranteed. I will describe them from the most harmless to the most kamikaze/deadliest. All of them will require you to open your device; if you are not careful and damage any of the components inside, you will end up with a worse device than before - but hey, don't say I didn't warn you.
At this point we assume that the cause of the problem is a faulty solder joint of your WiFi IC. The goal is to try to restore that solder joint. To do that, you will have to:
I. Open your device
II. Find your main board and separate it from all connected plugs
III. Find / identify the WiFi IC chip on the main board. I recommend searching for a service manual for your device, or/and searching for a disassembly video for your device; you need to know which one of the chips on the main board is the WiFi one.
Once you have identified your WiFi chip, you have 3 options, which you may combine with each other, but I recommend to try them out one-by-one as follows:
6.a Sellotape / Scotch tape
You need to make sure that your WiFi chip is pressed against the main board (ideally, this ensures the broken contacts touch each other, solving the problem). The best way to achieve this, is to attach a series of tape strips on the top of the WiFi chip, causing it to be pressed against the main board by the surrounding cover/hull once you reassemble/close the device. The tape strips are just a suggestion, do whatever you find convenient as long as you ensure that the chip is pushed against the board at all times.
This method may solve the WiFi problem already. When you turn your device back on, give it some time (5-10 minutes) and reboot it a few times if the problem still persists. My own WiFi didn't function right away, but after a while it finally recovered - hurray!
6.b Refrigerator / Freezer
Instead of using the tape as described in 6.a, you may first try to put your motherboard in a fridge for a few hours/days. But make sure to put it there in a plastic bag, and avoid moisture as much as you can, specially when taking it out of the fridge. Make sure its completely dry before reassembling your device!
By the way, try the refrigerator option BEFORE you try the freezer option!
6.c Oven
If everything else fails, the oven might be your last chance. This is not a joke, but as you probably can assume, it is "All-In" i.e. highly risky. The theory behind this is that high temperature will cause defective solder joints to reflow, reconnecting and thus fixing the problem.
You should only try this as a matter of last ressort. Be warned that you may fully destroy your main board, and there is a high chance that you will. Also, you may cause serious injury to yourself or others. Make sure you make backups of your data first. DO NOT BAKE THE WHOLE DEVICE, ONLY THE MAIN BOARD. DO NOT BAKE THE BATTERY!!
If you are still reading:
I. pre-heat your oven to 385° Fahrenheit (196° Celsius)
II. put your main board in the oven, bake it there for 7 minutes
III. remove from the oven, let it cool down until every component of the board has room temperature
Finally, here is a video of a guy doing a similar thing, but with a heat gun:

Ok, this is all, I hope I could help you.
Good luck!
Summary
Hello all,
first of all, I want to thank brysclar and xbing6 for their valuable feedback! Thanks a lot guys! :good:
Now, in an effort to update this thread and in an effort of trying to summarize it in fewer words (my disclaimer above applies!):
- The described problem seems to affect mainly (all kinds of) LG devices
- The issue seems to be caused by a defective soldering of the Wi-Fi chip on the main board
- The defect seems to be induced by dropping or/and overheating the device; recharging the battery, big/long app or android updates or the flashing of custom roms could cause excessive heating
- brysclar pointed out that replacing the battery might solve the problem (I haven't tried this out myself, so I can neither deny nor confirm this)
- My recommended solution is 6.a - applying pressure on the Wi-Fi chip, pushing it against the main board, using tape stripes
- There is a video of a brasilean guy doing some similar, but using pieces of an old credit card instead of tape strips: https://www.youtube.com/watch?v=OJkdva2iOag BUT PLEASE NOTE THAT HE IS APPLYING THE PRESSURE ON A RANDOM SPOT, NOT DIRECTLY TO THE WIFI CHIP! It *may* work for you, but if it doesn't, find/identify your Wi-Fi chip and apply the pressure there
- If everything else fails, and only as a matter of last ressort, you may try what I have written in 6.c
So... this thread has over 500 views, but not one single reply.
Guys... what has your experience been? Have you tried anything out from the posts above, and if so, what was the result? Did it help you? Do you recommend anything? Has something else, not written here, worked for you?
There are a lot of people out there having the same problem. It would be great if you could give any feedback, share anything that helps the community.

I honestly didn't see this post before. You really covered every detail very well. So far, returning my G3 to stock and replacing the battery has fixed it for me. Weird. I know. I did try 90% of the things on your "things that don't work" list and you are correct. They don't work.
wlanmac 02/00/00/00/00, Bluetooth is OK
Hey, i just got an LG LS990 with same Wifi issue and i'm ready to try so WITNESS ME!
Thanks for an amazing and detailed post lml
Simply awesome.
I have similar issue with my Nexus 5x. It is QCA6174 hw 3.2 chip, lspci does not detect this chip any more. I am going to do a little bit investigation from device driver (cnss) perspective. It enables one GPIO to provide power to this WiFi chip, I will try read back this GPIO status to see if it is enabled. I do not have the schematics, I do not know how to check if power is supplied to this wifi chip.
lspci used to show below:
$ ./lspci
00:00.0 PCI bridge: Airgo Networks Inc Device 0300 (rev ff)
01:00.0 Network controller: Atheros Communications Inc. Device 003e (rev ff) (this is qca6174)
If kernel driver investigation does not reveal anything helpful, I will ask other guys to replace the chip.
I thought it is because of vendor partition is accidentally wiped out, maybe it is unlikely.
---------- Post added at 08:49 PM ---------- Previous post was at 08:40 PM ----------
As Bluetooth can not be turned either, I am tending to think this is hardware related as well. As described previously, I will see if I can check that gpio status.

Hi xbing, and thank you for your feedback! :good:
I am really curious and looking forward to hear the results of your investigation! I believe that in your case, too, the Wi-Fi/BT chip is not being supplied correctly due to a defective soldering. Note that I don't think that the chip itself is defective, only the contacts between the chip and the main board. So, before replacing the chip, I'd recommend to first try what I've written in 6.a (or check my update/summary above).
Keep us posted about everything you find out!
Sprint declined to fix my LS990 due to "water damage" being the reason for it not working, and wanted to charge me a $150 deductible for a $100 phone. Shimming the WiFi chip against the metal covering with some thermal pad I had lying around and adding a bit of sticky foam on top of the ribbon cable for the camera worked great! Much thanks!

Hi NavHur,
since the problem is mostly caused by a loose Wi-Fi chip, respectively a defective solder joint, using thermal paste or grease is unlikely to help; again, what you need to do is to have your Wi-Fi chip pushed against your main board. You can use your imagination on how to accomplish this; what Tomcat5 described he did ultimately led to exactly having his chip being pressed against the board.
Of course you are free to try whatever you want - if you find new solutions please post some feedback.
Good luck.

Thanks you so much, I placed a small piece of plastic above the wifi chip and one next to the camera lens. Now the wifi works fine. However my screen was pushed up so it bended a little. The faulty thing was my battery, not the added plastic. I compared mine with the one of a friend, mine was 1 mm bigger. (also with the battery of my friend's g3 the screen was fine)
I'll be changing it soon.
same problem as u but sometimes wifi works(mainly fully charged) and sometimes dont
i have lg g2 D802 model. It had a wifi problem as u shown in your videos,my phone also behaves same like yours but sometimes it works normally like while charging,works like 2 or 3 times a day(for 5-10 min).please tell me whether my phone got ic problem or software issue

Hi Pratap94,
nobody, neither here in this forum nor elsewhere in the internet, will be able to give you a reliable answer without having a *physical* look at your phone. Nobody.
However, I can give you my opinion, based on the stuff you wrote: The fact that it works normally sometimes, specially while charging (probably it heats up in the process?), indeed seems to indicate a hardware issue. I believe you have a loose Wi-Fi chip i.e. a defective solder joint, like I had on my LG G2 D802 as well. I solved my problem by doing the stuff I described in 6.a.
Good luck.
Thank you so much

Hi Olzhas18,
that might be an indication that your WiFi chip is still a bit loose and is not sitting tight enough on the main board. On LG G2, it is difficult to push the chip against the board because it's covered by a metal cover...
Also, did you check out this video: https://www.youtube.com/watch?v=OJkdva2iOag ?
Good luck!

Thank you this tip and this whole thread. I have seen this video, but still the same effect. 5-10 minutes, I can rean some news and back to flashing. I'm going to buy Huawei Honor 8 soon, it was the last chance to recover my G4. I doubt I will purchase any other phone from LG.
Same boat
But bluetooth working
In cm roms also wifi tethring can be onn
But u cnt turn onn wifi
I had the same issue, can't turn on Wifi after factory reset.
I turn off my device off after one hour and reboot wifi was OK but when I want to upgrade some apps iwifi turn of again and my phone reboot with no SIM card.
I do "6.a Sellotape / Scotch tape" + a creedit card cut with this video https://www.youtube.com/watch?v=6_0jzp65eLY#t=73.319872
My LG G2 works fine
Owned the phone for about a month now. Phone was working perfectly fine for the majority of this time. I use 2 different sims and they were both working smoothly until recently.
A few days ago, I woke up and the phone wouldn't recognize the Sim cards anymore. I took out the Sim tray, cleaned the Sim cards and the tray as thoroughly as I could and they both started working again. A few days later, I restarted my phone and both of the Sims stopped working again.
This time nothing I would do would solve the matter, so for the next few days the phone wouldn't recognize either Sim. I have unlocked the bootloader and rooted, factory reset it and updated it none of which seems to solve the issue.
I use this phone for gaming so last night to my surprise one of the Sims started working (sim was in for a couple of days) and all connectivity was perfectly fine - I tried putting in my other Sim as well but again the phone wouldn't recognize them anymore. Tried putting in only one card on the Sim 1 slot but it made no difference. I don't understand what the issue could be.
Do you have a converted CN version or did you buy a global version? (just curious, as far as I know only CN -> WW versions faced this issue and I would like to know if this is a coincidence or an issue with these versions. But I could be wrong as well)
Nevertheless I would make use of warranty and send it back to Asus to get it repaired.
Yeah it's CN version > WW ROM. It's absurd how randomly it was hit with this issue. Again, the phone was reading a sim card perfectly fine out of the blue last night, then when I took out the Sim tray to insert another card, went back to square one and wouldn't recognize either.
I know.. If you had searched this forum or the rog reddit you would have noticed there are multiple topics like yours and all people explained the very same. Seems totally random.. sometimes it works, sometimes not. Unfortunately no one was ever able to post an accurate answer of why this is the case or how to fix it. At least there is none here, on reddit or the zentalk forums.
Since all device so far were CN -> WW version I don't know any successful case. Asus mostly rejects the support and redirects people to their sellers but those mostly refuse to do something. (they probably know that issue and it's cheaper to do nothing)
I wish you best of luck. Maybe you could try to contact Asus and report the outcome so we finally have a documented successful repair.
Edit: as said, that's only my knowledge, maybe there is a fix and someone found a way but they either didn't publish it or they posted it in a not so well known forum.
I wonder if the connections that touch the SIM are poorly designed. If it is such a widespread issue that randomly seems to come and go, it could be similar to the issue I had with the Kunai 3.
The pins on the side are designed to give a little when sliding the controller off and on the mount or charger. After moving them between the mount and charger twice, some pins fell off and others never popped back into place so they could make a connection. It turns out they never secured the pins well enough to handle it.
Hello, I had a similar issue.
My sim-cards wouldnt be recognized, sometimes only one of them, sometimes both. Additionally, my fingerprint-sensor wasnt working too. By checking pictures of a disassembled phone I could locate the problem inside. It has a connector on the lower end of the phone, which is for sim and FP-sensor. I can definitely and easily come loose.
Quick and dirty fix for me, was pressing with controlled but quite some force on the lower end of the LED-Rog logo while the phone laying flat on the table. I used my thumb, pushed and restarted the phone to check. Didnt work, pushed a bit harder and restarted again until it worked. The back glass has some flex to it, to make it possible to push the connector back in. Still, be careful to not break it, if you try it yourself.
When I found that solution, I've sent it in on warranty for proper fixing with this Information to ASUS. They replaced allegedly the mainboard. But I actually think, they just fixed the connector in place, because bending the phone to a certain degree "unfixed" it in my case again. I dont know, if its the same issue you have, but if it is, hope it helps everyone.

Good tip and glad it worked - this could help a few out there. Perhaps ASUS should have included some instructions explaining how to press/bend the device back in order when it happens ...
I had the same issue and quickly found a fix. I bought a OnePlus 9 Pro and relegated this glitchy piece of junk to my desk drawer. Good riddance.

Paying over $2,000 for a OnePlus 9 Pro seems like an expensive solution, but I am glad it worked out for you. Best of luck over there.

Works like a charm here! Congratz!
Omg worked here too, now I have a Poco F3 AND a revived ROG Phone 5...

You are the mvp. I love this phone and using it for almost a year. Suddenly sim no longer detected. I tried everything, unlocked bootloader, update firmware. Hour and hours of trying to revive it. I even called Asus and they said to call the Chinese warranty support. Then finally came across this thread. Pressed down hard on the lower end of the logo of the phone on its back. Restarted and now it's detecting the sim again. Thank you so much
