HELP no sim or SD detected - Xiaomi Poco F1 Questions & Answers

I was on evox everything was fine and i thought id try the new Havok, i clean flashed as normal and (this happened before but only for alittle and format fixed it) now my SD or my SIM arent being recognized, not even in TWRP.
I tried reflashing vendor/firmware, format, wiped everything still SD wasnt being detected but it did show up on PC and i saved all my data. I then formated SD and still no detection.
I reflashed EVO and all worked except sim and SD, so i went and did a full miui flash with mi tool.
Im now at miui setup page and its asking me for sim when its in there, tested my sim in my friend iphone and it works.
Is my phone burned?

well in the end after a hard shake of my phone the sim and sd it started working again, for how long? who knows.
phone repair guy said it would cost probably 300-400-500shekelw to solder, the phone was bought for 1000 so fk it.
question if anyone knows this is the phone signal graph from gsam, it used to never go below 40,, does this mean im losing connection during the day?

Yes. If you travel with the phone, this may be normal. If the phone is in one place the whole time, then either you have an issue or your mobile tower/provider has.

I was completely static sitting at work when these readings were taken, thing is same type of graph happens at home also . Previously the graph would be always between 40 to 80 and no sharp ups or downs all just normal(fromnexactly same locations) and this erratic signal only started after i lost my sd and sim connection for like 12 hours (shaking the phone brought it back which leads me to think it hardware).
My gf once shoved in a pin to eject the sd and i think she did it too far or something and nicked some solder point since shortly after the sim and sd stopped working, but everything went back to normal after a while. This second time it happened again that i lost sim and sd and now i have this erratic graph where it says my signal is at 0 but i still got a call.
Jsut to try i switched from evox to crdroid and i observed the same type of signal graph so its not a rom thing.

these readings are from when i switched roms to test and its the same.

Apart from Gsam showing these readings, do you have any issues with calls? If not, I would simply ignore it.

I had problems with download speeds, i was getting like half normal.
I FIXED it though with a bushfix, i put like 4 layers of cellophane tape on my sim card and now it seems it presses it in better, my stats are now steady between 40-80 depending if im indoors or out, no drop offs at all.
I hope this lasts! if not looking into mi 9 or K20 pro.

I'm having the same bs with mine (losing SIM and sd card access periodically). I have the added ballache of random shutdowns for hours at a time.
After noticing one side of the SIM tray was slightly worn down and wondering if it wasn't pressing the cards onto the terminals sufficiently firmly, I tried adding tape. One layer didn't do the trick and I was reluctant to use more and get it stuck inside the phone.
I've ordered a new SIM tray from Ali express - hope this will do the trick

Really grinds my gears having this stuff happen, at first i thought the connectors were broken, im not sure if its the tray though cuz i took my girls poco sim tray with her sd an last time it dint detect hers either.
Try what i did first to see if it helps, 3/4 layers of the clear tape, put it on the sd n cut to size.

Soo you are saying that sometimes your simcard would randomly die with no reason, and even after getting out and putting back didn't 100% fixed it?
Also that your phone suddenly died for like 2 hour and you couldn't start it no matter what?
Cuz i had these 2 problems.

Yup, that's what has been happening. Sometimes popping out the SIM and reinserting it helps, but often it doesn't. I've found it happens less when the SIM is in the SIM 1 slot rather than SIM 2, meaning I can't use an SD card. Makes me wonder though if it's mechanical, hence whether a new SIM tray might help
Random shutdowns are a PITA. They've lasted days before now
I returned it to Xiaomi for repair. They found it started up and returned it insisting it is fine. Despite videos showing the problem. Waste of time!
Did you manage to get yours over this or is it still happening?

It didn't happend after 3 shut downs. And neither the sim issues. Just to be sure i CLEAN FLASHED AND LOCKED BOOTLOADER than unlocked again and clean flashed latest xiaomi eu. Since then i didn't had any of those problems (but i got another one, maybe because of malakas kernel, rarely my screen would get stuck and only reboot could fix it(or touch sensor, not the OS)

I've done factory resets, without any improvement, but haven't relocked my bootloader
Might try that if I can summon the resolve
I've half convinced myself that it's a mechanical thing though with the positioning of the SIM card seeming to make a difference...

I had the same, couldn't fix it and i got mad and put it in slot 2,whitout sdcsrd, than it worked, i was afraid that i bricked sim 1 (its sim 0 in reality but doesn't matter), than i put it back and never had problems since than. I recommend you to:
Clean Flash back 9.6.27 beta with miflash (while relock bootloader)
Unlock bootloader, install twrp, CLEAN FLASH (well i didn't wiped system cuz some people said that on the forum, and tbh doesn't affected me) latest xiaomi eu (again, whitout wiping system but wiping all), install malakas kernel and latest magisk (13 or even 14) and if you want install FDE.Ai.
If you have problems even after all of this, than it's maybe damaged hardware, which is very unlikely.

my sim has been with stable signal strength since i put acouple layers of tape on the top.
flashing things ddidn't help me at all. I was considering mi9 to replace but developpement on K20pro looks like it will b way better.
so dar everything works so ill wait a couple months before buying a new phone.

I've just been on holiday for a week, during which time I had no shutdowns at all. Could be total coincidence, but a few days before I went I moved the SIM from slot 2 to slot 1. I've done this previously and still had random shutdowns, but strangely this time it seems to be behaving currently. Most odd

I never had problems agaon, BUT like 2 days my sdcard disconnected and could never put it back, even if it worked in another phone...

Solution?
Recap: since my F1 was about 3 months old I've been getting apparently random shutdowns lasting moments to months, also similarly sporadic signal loss and disconnection of the SD card. Have returned it to the manufacturer who took a bunch of cash from me, found it worked when they turned it on and returned it to me. A couple of days after receiving it back it shut down and continued to do so, exactly as before I sent it off. I started putting the SIM in the other slot and it worked reliably for about a month, then it all went to rat **** again.
About 2 weeks ago it shut down and wouldn't restart since. Pissed off with it and content that the warranty has no value, I took the back off last night and found that the antenna connection was loose. I pushed it in firmly (along with all the other connections to the motherboard - battery, screen etc) and fastened down the black motherboard bracket / plate / cover a bit more securely than previously, put it all back together and....
When I pressed the power button it sprang into life!
First time in 2 weeks and it's been steady as a rock since
I hope I'm not posting this prematurely - that the problem won't recur now I've tempted fate, but the initial signs seem promising
Kind of wish I'd got my screwdriver out 7 months ago and saved myself all the fannying about!
Btw, this teardown was helpful in case anyone wants to take the plunge https://youtu.be/LlubcWbsSQk

Turning off

I just purchased my HTC Amaze five days ago and it is randomly turning off. It hasn't happened while using it, but it seems like every day now it has turned off while I haven't been using it. I push the lock button to unlock the phone and it is simply off. When I turn it back on everything is fine, but it is getting really old having to turn it back on so often. At first I thought maybe I was holding the lock button too long and accidentally turning it off, but that is not the case and the phone has been sitting on a table most times it has turned off without a case so the button isn't being pressed accidentally. The battery has more than half of the charge left so that shouldn't be the problem either. The phone just has the standard tmobile apps that came with it so that shouldn't be causing a problem.
Is this common? Is there a setting on the phone that turns it off automatically after awhile or at a certain time? If there isn't a setting is there a way for me to fix the phone or is it simply defective? I didn't buy the extra warranty, but I am within the 14 days to return the phone but it says on the box there is a 50 dollar restocking fee.
I bet there would be no function called automatic turn-off on this phone...and personally I have never faced this issue so far, during my half month period of daily use. Even there is a charge (which I never know), I would still suggest go for exchange. Random turn-off may relates to hardware defect, and is difficult to fix through software change. Try another one and hopefully that would take your headache away. Good luck.

Exactly what I think.
OP: If you are within the grace period, you can exchange the phone without restocking fee, especially if your device is defective.
Good luck!
Two other things I thought might be completely unrelated is that whenever I turn the phone on it says no sim card and then recognizes that there is a sim card and gets a signal and starts working immediately after that.
The other thing is that it says new voice mail whenever I turn the phone on, but when I check the voice mail there is none.
I took the sim card and battery out and put them back in. The no sim card message on start up is gone for now at least. The odd thing I noticed when I put the sim card in is it seems to slide in too easy. On my old phones I am used to a little bit of resistance when putting the sim in, but on this phone it goes in really easy, almost too easy. It seems like it could be easily jarred or even vibrated loose.
Is it supposed to be so easy to slide? Would the phone turn off if it stopped recognizing the sim card?
Thanks for the replies, I haven't ignored them, I am just trying to avoid having to go all the way back to the store, but I will if it shuts down again.

A loose sim card causing shutdowns? Hard to imagine how.
I just checked mine, and the metal restrainer is keeping my sim card pretty tight. It is not supposed to be moving around as you guessed.
My sim card sits pretty tight too. The "no sim card" message also pops up every time I turn on the phone. Guess the phone needs a short period to detect whether the sim card is there. For the voice mail I have no clue yet, check with your carrier maybe. Within the grace period I guess you could use this loose problem to support your demand and hopefully the store would not charge you any.
For the random reboot issue, try to do a master reset and that should help. I had that same problem the first few days i used it but after the reset it went away. It wouldnt hurt to try. Just remember all the free apps you downloaded because they will go away.

For the ghost v-mail...use a different phone or have someone call you and leave you a v-mail...as soon as you delete it the ghost voice mail will be gone too. I used to get these all the time on my HD2 and when I called T-Mobile that is what they told me to do...works everytime, until it pops up again. It was explained to me that it happens because you HAD a v-mail at one time and it got stuck in limbo when you deleted it, thus a ghost v-mail.
Thank you for all the help. The factory reset fixed the phone. It hasn't turned off once since I reset it several days ago and it was doing it every day before. Leaving a voicemail also fixed the voicemail that wouldn't go away.

Problem with network: "Sim card has been removed"

Hello.
I have problem with my Elephone P9000. When the network signal is poor, the network indicator loses signal for a few seconds and in this time, the message "Sim card has been removed" appears for a moment. After that, the signal turns back on (4G), very quickly switches to 3G, and this situation repeats after minute or two. I checked on other sim cards, and the problem is still present. I've done manual upgrade to 20160315, and it not helped. I wonder if it's hardware problem or the software has some bugs.

Hi,
I had the same problem... My p9000 has arrived just a week ago and since the beginning, several time per day, specially when the phone was in my pocket, it appended to lose contact with the Sim card and even with the SD card. I tried to put a piece of tape on the back side of the tray Sim holder... and after few days it seems work....if can be useful
Thanks, but this method did't work. I noticed, that phone loses network even when signal power is about 3/4. I'm writing to elephone right now.
I have the same problem, my p9000 arrived today.. after setingup everything the simcard cannot be read.
I tried multiple solutions none of them work. anyone already got the solution?
I had a small succes with 2 simcards but it lasted a short time

Flashing Aerom V1 solved my problem.
Friend of mine received this phone yesterday and has the same issue. They keep getting this error every few minutes even when the phone is placed on a table so I reckon it's firmware related?

Yes. ROM 20160419 and every other based on it solves this issue.

It doesn't. I received the OTA and I still have the problem.
It's strange. I installeg IMUI official rom, based on 0419 and still was fine, till i started to play with LTE bands. Disconnecting sim card problem appeard again. Then i flashed stock 0315, download OTA and problem has gone.
Maybe a solution with scotch tape on back of the sim card will be useful to you.

I have this issue after the upgrade also. I do not think its hardware related as the issue can pop up even when the phone is sitting on a bench.
I have 2 SIMs in the phone, and it seems to happen much more than when there is just one.
It feels like when there is multiple connections that the phone gets confused and drops out.
The phone drops out while on calls too, which makes it worthless to me.
Is it faulty? Should I send it back?
I have the same problem with my P9000.
It looks like some mobile data information seems to cause some kind of exception which will then drop out the SIM card.
I had the same problem. So I ordered another P9000. Problem solved, second phone works fine. I swapped the SIM card trays to verify, the problem (in my case anyway) is with the tray as the old tray causes the same problem in the new phone and the new tray works fine in the old phone (damaged/bent/bad batch/different manufacturer/sub-contracted? Who knows?). Wrote to Elephone (for a replacement SIM card tray), will see what they have to say.
(As a very unsatisfactory workaround, if you bend the tray very slightly (bend the middle down from the top) and insert it in the slot almost all the way except for the last 0.3-0.5mm (friction holds it in place), so it protrudes about the same distance as the buttons (so it looks like another button) then this seems to hold the SIM card in the right place. It is a bit tricky but do it right and it stays in place (a few weeks now, no problems). If you break it it is your responsibility not mine, though (let's see if Elephone will give replacements). Best solution I could come up with as the alternative is owning a $200 piece of plastic that does nothing. (now I have two (3 actually) dual SIM card phones. Lucky I have a lot of SIM cards.

I removed the SIM card tray because I wanted to swop the SIM's around. It has been several hours now with no drop out so it will be interesting to see how long it works before droppping out again. I didn't dare to bend the tray because knowing me I would have broken it!
Duplicated in error.
search for lost imei on mtl devices.
you can restore it with enginnering mode . its easy

Did you manage to get a replacement tray? I'm having this issue on a second p9000 I bought and can't seem to find a proper solution
I've had one drop out only since I removed and re-inserted the SIM card tray as per my post no #13.
I did inform Elephone of the problem but apart from a standard automated acknowledgement, I never had a response. What a surprise!
That's bad news. I've got a third p9000 and it's the only one causing problems. I've factory reset it and hope the seller takes it back as no matter what it won't detect the SD card in the first slot or the SIM card in either now. The QA on this sim tray is really bad. There aren't any compatible parts for the tray anywhere? Does the tray share the same design as say a p8000 or other elephone models? Or even a different phone entirely?
I have the same issue. I even had to remove the SIM pincode, because after the phone thought the SIMS had been removed and later found them again it keeps hanging on the SIM lock. This sometimes happens in my pocket without me knowing that i do not have a network connection at that time.
So how can we decide if it's hardware of software related?
Software: In my opinion this issue only came about after updating to the 20160419 ROM.
Hardware: Once the phone suddenly found my SIMS again after hitting it softly (softly, i swear).
I will be following this thread closely
I have the problem too, the First weeks I had no problem. Now it happens from time to time around two times a Day. I'm using Eragon 2.0.

SIM card frequently disconnected

Hi all,
I have the G5 since May and have the following issue.
Since about a month the phone doesn't "see" the SIM card from time to time and there's nothing I can do beside rebooting, which then recognizes the SIM again. Screenshot attached.
This has been getting worse, to the point where, today, the connection won't last longer than 5 minutes and then I have to reboot
I am unsure if it's more HW or SW, as the reboot normally fixes the issue. I have also tried to extract the sim tray, "clean" the card and re-insert it, which didn't seem to change a lot. Today I haven't tried that yet as I'm on WIFI and the phone is undergoing a system upgrade.
Has anyone had this issue??
Thanks..
Did you tried to contact lg?
I also have this issue, though mine seems to have degenerated at a much faster rate than yours. It started this morning when I think I got some water in it from the shower? Perhaps that is related?

That is definitely related. I hope you dried it out before continuing to use? I know where all guilty of this. But when you take it to bathroom for shower. Put a towel over phone. Away from shower so no moisture or splashed water gets to it.

Hardware or Software problem? Screen issues

Sunday I started having issues with my display, and I'm wondering if it is a software or hardware issue. It is on stock 47A software that is rooted with KingRoot. At times, the display will either blank out (black screen, but the backlight is still on) or random vertical stripes on top of the screen. If I toggle the power button to turn the display off, then back on, the lock screen display comes on, and sometimes I can draw my pattern before the issue pops up again, and sometimes I can't. Whenever I'm finally able to get past the lock screen, the app that I was in before is still in the same spot. The only thing that I can think of that may have caused the problem is that Saturday night I left the phone in my truck overnight in 38 degree weather and the battery was completely dead when I got it out the next morning. Any suggestions?
i had a similar problem over the weekend. my screen started acting flaky. when the screen did work, it would fade to black after a few seconds. the digitizer and buttons still worked. my phone would respond to screen unlocks and i was even able to answer a call when the screen wasn't working. also, another problem i had for the last month was that sometimes the camera app would show purple lines all over the screen and they would be captured in the image.
i ended up opening up my phone and disconnecting and reconnecting the connectors for the camera and display. this seems to have fixed my issues. my screen works fine again and my camera isn't showing the purple lines anymore. i've dropped my phone quite a few times, which probably shook some connectors loose. reseating them seems to have done the trick. while my phone was apart, i also baked the motherboard in an oven for 10 minutes at 320 degrees F. maybe this helped, but my guess is that reseating the connectors is what fixed my problems.

I tried reseating the connections over the weekend, but still having issues with it today. I'm hoping to find some time to get TWRP loaded and try a custom ROM to see if the issue is still there.

Have you tried going back to pure stock, no root, no TWRP? Also, did you just flash a custom ROM and the problems started happening? If you haven't flashed recently, and going back to pure stock doesn't cure the issue, I'd say it's a hardware issue.
How old is your phone? Mine is almost 2 years and just after accepting the 49A OTA, my SD card no longer works reliably. I've flashed back to previous stock versions, used various different cards, looked at the motherboard, reseated all connectors and the problem still persists, so mine is definitely a hardware problem.
So, if you go through all the things I did and the screen still acts flakey, then I'd say it's definitely a hardware problem.

I don't have TWRP installed on it. It is on the Verizon 47A stock version, rooted with Kingroot, so it loses root after reboots. I have not made any software changes for a few months. I did leave my phone in my truck overnight the night before this started happening. I think it got down to the 30s or 40s that night, so nothing extreme.

Not sure if that could cause it or not, but I had an issue with a lap top that I left in my trunk overnight and it got into the 30s and the screen had issues after that. That could be the issue. If so, it's definitely a hardware problem and you'll have to replace the touch screen glass and digitizer together.
for me, reseating the connectors only bought me a few more days. i tried opening up my phone again and reseating the connectors once more, but that didn't help. my screen will stay on for a few minutes before having issues. sometimes the image freezes and then slowly fades away. the digitizer still responds to my actions. i just can't see what i'm doing. i guess it's time to upgrade. too bad i missed verizon's black friday deal on the pixel xl. in the meantime, i'm using my old galaxy nexus that i resurrected.

I feel your pain. I was looking at that, but VZW only would give me $40 for my G3 if I traded it in. That still left over $600 to pay for the Pixel.
The only issue with my phone is the SD card slot is bad. Everything else works, so I can live with this phone for as long as it will last. Once it dies, not sure what to do next.

I have 3 G3s on my plan that I upgraded on black Friday with a Moto Z Droid, Moto Z Droid Force, and a Pixel XL for me. While I wait for the Pixel XL to come in, I'm using one of the other G3s. I tried taking the motherboard out of mine to swap with another phone, and the problem followed the motherboard. Unfortunately the other 2 phones weren't rooted, so they are on the 49A software, which I haven't seen how to root.

nicely done. i'd like to upgrade to the pixel xl, if it ever becomes available. hopefully there's some kind of deal when it does. i saw the moto z in the verizon store. the moto mods are interesting.
i think you can downgrade from 49a to 10b and then root and upgrade from there.

I started to try to, but was having trouble, and didn't have time to figure it out. My XL is scheduled to ship on Jan 6th. I think if you order it now, the scheduled ship date is 1/13.

[Help] My Phone is acting weird

My Phone sometimes lock the screen for no reason and totally random there is no pattern to know why it does so. it is really weird and pissing me off..
also my Sim card most of the time now isn't detected and other times it is detected totally random as well for god knows why !! I don't know what the hell is up with the phone but it's just the first time to have such a thing happening to me..
I didn't root it, didn't download any unsafe apps ,and didn't do anything unusual with it. just out of no where started acting weird..
you have to be more specific with ROM, version, vendor version, Magisk Version, kernel details !
if MIUI ? then which version / built/ cn / Dev ?
This kind of thing was happening a lot with mine, for no obvious reason. Stock rom. Also unprompted shutdowns, sometimes refusing to restart (for weeks at a time!)
It got really bad. I returned it to xiaomi, with footage of it refusing to start
They emailed me a video of their person restarting it. I explained again that it was an intermittent fault, but they just returned it me (after asking me whether it not I wanted it back!) I was without it about 6 weeks in all
It arrived, working.initially, and within 24 hrs it had shutdown again and continued to do so
Frustrated I took the back off, took it all apart and found that the antenna connection was a bit loose. Pressed in all the plugs (screen, battery etc) and screwed in the retaining plate good and tight. Put it all back together
Bingo!
No shutdowns since!
Took about 45 minutes and a steady hand
Can't be sure if it will work for you, but it's got my phone working again
Edit:
Just noticed your other post, mentioning recurrent reboots - all sounding quite consistent with my experience... Just saying
There are some good teardown videos on YouTube!

I didn't change the rom so it's miui global 10.3.8 stable and the kernel version is 4.9.112-perf-g4aff1b2

mine would just keep locking the screen it doesn't restart or shutdown and refuse to open. gonna try to reset the phone before I try to tear it down
Xiaomi technical service is just trash. and I don't have warranty so it will be even harder.
btw the other post was for another phone.

Absolutely - I'd recommend resetting a few steps ahead of getting out the screwdriver!
