I bought a Pocophone online, received it, and used it for about a month.
After one month, after Turning it off and back on completely, the wifi and cellular didn't work anymore. (was on MIUI)
I reflashed MIUI from TWRP, thinking it would solve the problem, but now I was stuck :
When you boot up MIUI for the first time (or after reflashing) you need to enter your MIUI account code to go on with the setup process. But that's no use, because with no Wifi or cellular, the phone cant check the password.
I have the IMEI (I don't know for the MAC address) printed on a sticker on the phone's box, but I didn't want to change it myself because I understand that's not completely legal ?... Anyway, I sent it back to client service and waited. They received it, and acknowledged the problem, but as they're an online reseller (big place in my country) they "sent it back to Xiaomi". So I waited again. Now, they're telling me that
Their technicians have denounced the warranty on the grounds that your equipment has been oxidized.
The cost of repairing your device is equivalent to the price of new equipment and has therefore been declared economically irreparable.

I know that's false, but I'm not in a position to tell them anything, so when I get my phone back, I'd like some pointers on how to fix it myself. I'm pretty sure I've got to fix the EFS partition, but don't know how.
I know this is not a hardware problem because the phone is still able to scan, and see and list wifi networks, and the message specifically says there is no IMEI and MAC adress.
Thanks to all of you !

Short & simple method. Flash a custom rom. It will solve your miui account issue. But I don't know if that will solve your wifi issue as well

Yes I tried this when i still had it, but the IMEI and Mac adress are still missing. A phone that cant "phone" is of no use...
Sorry to hear about your loss, how can they say it iodized? Whatever you can use it for a bit of experiments. Do you have any twrp backup if yes you can restore it .if not you can try with any efs backup of nay other device..not sure its possible or not any one here with more knowledge can do this and many in markets can do it too if you can provide them the proof of a legal purchase
I have even worse problem

My problem is activating phone after doing factory data reset.
Could not complete boot unlock so did factory reset. First screen after reset is black showing "device is locked"and has choice to "activate this device". OK, push that so get scree to enter password so I enter my Mi Account pwd but not work, get message "this device is associated with existing MI Account (186****877). Thiat number is NOT my Mi Account but must be locked inside my phone. I bought this new from Lazada and have no way get at that existing account. So what to do now??

I didnt do to much research, but this looks like it's an official seller. just send it to them for warranty.
Update : Deleted
Phone exchanged and files deleted.
Thank you for the offer but just a bit too chancy and i very much want my Pocophone to be just fully functional phone. The Lazada purchase was very much a legal purchase but the Lazada suppliers are individual shops which may be or not "Official" Xiaomi dealers. I have sent the phone in box and with copy of my receipt to Xiaomi in Bangkok, and hope to have good news from them after New Year. Hope and trust in Xiaomi doing the right thing; Thailand is not strong on customer protection.

Is it possible to use your file and then change the iemi and mac address?
I had to flash to miui 9 in order to get into my phone now I can see my iemi and mac adress are unknown.
Im hoping I have the box still somewhere in order to restore the iemi with some application.
But not sure if there is anything else that can still be broken
lost my imei too i got them writen on the box but i think there is no working way to get them back in the phone

Yea, this is the exact thing thats happened to me (Indian version).
Fresh out of the box phone, worked fine for the last 3-4 days.
Now I'm out on a vacation, and the network selection on roaming was flaky, I was toggling the network selection manually/automatically a few times to get some network, and the next thing I know I no longer have a IMEI (shows unknown) , and the same for baseband ( shows unknown) .
Tried factory resetting , etc, not helping. Will get back home and have the phone repaired/replaced.

This airplane mode sounds dangerous. Unfortunately it may be a necessity when you are travelling etc. Hope there is a known fix or one comes out soon. Until then I will keep my /efs partition backup in 3-datacenter redundant storage place along with my laptop and ext.hdd.
i just recieved an sgs2 in uk and it has this exact problem out of the box.
grrr
if anyone wants to point me to a stock rom for it i'll try flashing it
erm, i dont think flashing will help here.
I reckon that missing IMEI means the /efs partition has been wiped out/corrupted, and that is something which cannot be restored by a simple flash.
finally, after almost 12 days, lots of running around, I finally got my S2 working again.
The service center had to send the phone to their head office since they hadnt received any service info on the new model till then.
They changed the PBA apparently , and finally reflashed it and gave it to me.
They claimed that the flashing was an online process and samsung india service servers were down for nearly 2-3 days, accounting for the additional delay.
Just like my I9000, but I dont think it is the same problem and same way to solve.
I rooted the devise and deleted the nv_date.bin and the nv_data.md5 in EFS file with Root Explorer, and renamed the .nv_data.bak into nv_data.bin, then restart, problem solved
I have exactly the same problem as you guys are talking about. Really weird. The /efs directory, where is it located? Is it located in the main "Root" or is it in a specific folder? I would like to try the thing with the rename trick?

I got my samsung galaxy s2 this month. Everything is ok until the day before yesterday. When I try to make a call, it says "mobile network not available". I go to the setting--->wireless and network--->mobile networks--->select/unselect use packet data, there is no icon indicator it is activate as it should be. I tried the factory data reset, but the problem is still unsolved. Thus far, call/message stop working. Wifi is OK. Do you have any suggestion on that? Thanks.
Please check your IMEI, and your Baseband version.
If they are not available, you will need to restore your EFS, if you do not have a backup, you will have to visit Samsung Service Center, or repair the EFS yourself.
Do not use another phone's copy of EFS as it is illegal to modify or clone your IMEI number in most (if not all) countries. You can however use someone's EFS backup, and mod it with your phone's IMEI if you know how to.
Hi,
I'm in this horrible situation: no baseband, no IMEI. By ny chance, do you know how to get a EFS backup and change to my IMEI?
I appreciate any help. I was trying to make a call, the person on the other side could not hear me. I reboot and...lost my baseband. Checked IMEI, it was also missing.
Thanks

have u solved your problem? I got something quite similar...
In my sad experience, your only chance is going to Samsung and ask them to restore your IMEI. From what Samsung in BRazil told me, it should be in the same country of the device. As my device was imported from the UK, Samsung Brazil could not do anything, as IMEI database is Country restricted. I believe this info is correct as the representative was very helpful. It did not look like a lame excuse. If your device is not under warranty, it should not cost you more than U$ 50. That was the price here, and everything in Brazil is so expensive these days.
My solution was to buy another Galaxy S II in Brazil as it had been released here in between the time I imported mine and the time it got screwed.
Wish you good luck.

I've got the same problem...
does anyone have came up with a good solution?
Try this
Root your phone.
Go to efs folder in root. Go to imei folder in that you will find a file named mps_code. Edit it using root browser from market. Erase everything and type your original imei no. and save it.
Reboot your phone and now check.
Cannot guarantee it but it worked on mine. Good luck

It would appear this may be an issue common to a number of Chinese phones, so hopefully this will be of use to other people in the same situation.
Hey all,
So I've ran into a snag on my XT910 over the past few days.
Randomly, the device just dropped signal one evening and it never recovered it. Having troubleshooted with my network (O2 UK) and trying other SIM cards in the device, I have narrowed it down to the "Unknown baseband" or "No IMEI" symptoms found on these forums.. The device downright refuses to read (or even acknowledge the existance of) any SIM cards at all. It doesn't prompt for one to be inserted; it just says "No Service" where my network name should be, with an antenna and red "x" where the signal bars should be. Trying a working micro SIM from my girlfriends phone yields the same result. It doesn't even know it is in there.. In "About phone" it says Unknown baseband and dialing *#06# from my device gives a blank IMEI. Adding/viewing contacts on the SIM returns an error. I went so far as to get a brand new SIM from my network - still no dice.
The device is less than a month old and still under Moto warranty. However, the company I bought it from have neglected to provide a VAT receipt and I'm having trouble getting it off them. Moto have agreed to repair/replace the phone, but on the condition I have this receipt and send a copy of it to them. I really need this phone working, as it's the lifeline to my work, so I am willing to try reflashing/rooting the device ROM or radio as need be.
After some reading I have followed QPST guides to re-input the IMEI on my device, however it still exists and is correct. I have hard reset the phone, booted into recovery and wiped cache/data but no change.. I am considering the method of re-flashing the official OTA update for ICS, as I've read many users have this issue after upgrading, here: http://forum.xda-developers.com/showthread.php?t=1849744 - that is the correct ROM for my phone, but as I am already on that ROM I do not know whether flashing it on top will break things - ultimately brick it?
The device was (and still is) on 672.180.41.XT910.Retail.en.EU. I have not flashed any custom ROMs or rooted it. I have made no software or firmware changes to the device.
Please can someone help?! I do not mind getting my hands dirty and even voiding the Moto warranty if it fixes it (I would also be prepared to root it) but I am at a loss here - all pointers go to hardware fault and if that is indeed what it is, I would prefer somebody back up my assumption so I can send it to Moto knowing there was nothing I can do, rather than being a simple ROM flash away from having my device back..
Your phone may be damaged either physically (e.g. broken contacts SIM card slot) or software-wise (e.g. damaged PDS partition).
I'd go for a reflash, though - at least when properly executed it won't worsen your phone's condition. First, get full 672.180.41.XT910.Retail.en.EU flash file. Then, flash it using RSD Lite.

If it doesn't work by reflashing, can I still send it to Motorola under warranty for a hardware fix?

Hey,
I've just reflashed with RSD and I still get "Unknown baseband version" and no IMEI on the device. I guess it must be a hardware fault somewhere along the line.. Thank you regardless - and if you have any further suggestions then please do let me know.

Firstly, thank you to all who replied to or considered my plea.
Secondly, after extensive research and some testing on my part I have found this is a seemingly irresolvable hardware (or very heavily damaged software) problem. Through various threads online I have read about people getting this mostly after they upgrade their Razr to ICS. It doesn't seem to be limited to one specific baseband/regional version of the device, as customers on Verizon in the States have had the same issue I have in the UK with a SIM-free phone.
I have sent the device off to Motorola for repair/replacement. I will report back when I get the device back.

Hi guys, I know this is an another post on the same problem, but I follow all trhead on this argument without result.
I have an samsung galaxy s2 whit null emai. I lost it! But I have an old backup of EFS (I thinks it is corrupt because if I restore it, does not change anything )
I tried to restore whitouth success from this backup
I tried factory restore
I tried to recreate the EFS folder whit your two guides
I tried to flash the original firmware from odin whit auto reboot - repartition - F. reset time (I use the file from original firmware but I do not get even a generic imei, it stay null)
I don't know what I can do, and I can't pay 100$ for jtag box only for re enter my own emai
I have another samsung galaxy s2 where the software working (my sister's phone) but has hardware problems. Can I make a full dump of rom and pass it in my phone?
there is a way?
P.S. sorry for my bad english.
updating: I tried to put the EFS folder from my sister's phone to mine but the imei still remains null.
P.S. Sorry for the wrong section
Trying to put the EFS folder from another phone into yours will never work, and changing the IMEI is illegal in most places anyway if you use a particular piece of hardware that mobile repair shops/Samsung authorised repairers use to 'write' the IMEI back to the phone if you bork it.
If you don't have a good EFS backup, it's a service centre job normally, but there are quite a few threads on here which claim to be able to fix it. You might want to look at those; I can see you've obviously tried some things, unless you want to take it in to be repaired, keep trying stuff.
I don't recommend you try to fix this yourself with a JTAG box/similar for two reasons:-
1) You'll be paying for something you'll never use again
2) If you mess it up, it will be a service centre job anyway (or if you slip with the soldering iron, you could damage the phone beyond repair) which you'll pay for plus the cost of the box which you'll never user again.
So take it to someone who knows what they're doing.
No. Trying to copy details from another phone will not fix the problem because the IMEI is a unique hardware identifier which is assigned to the particular radio in your phone.
Same here!
I purchased this phone from a eBay seller and had it shipped to India. Didn't compare IMEI with the one under the battery (stupid, I know) when opening the package, or before flashing to JB firmware. Next thing I know, phone calls are not going and emergency calls only available, even though data network is working fine.
What I did after that (no particular order):
1. Flashed with stock GB, ICS and JB
2. Rooted
3. Tried fixing by steps in http://forum.xda-developers.com/showthread.php?t=1264021&highlight=recovery+IMEI
4. Tried fixing using SGII_Repair
5. Tried fixing using HC-kTool
All failed!
Next option looks like buying a SRS licence and changing IMEI to what is there under the battery. Would this work safely, and restore order to normal in phone? Anyone!! Phone is perfectly new, no signs of use, so assume that I was shipped a proper piece.

1) You'll be paying for something you'll never use again
2) If you mess it up, it will be a service centre job anyway (or if you slip with the soldering iron, you could damage the phone beyond repair) which you'll pay for plus the cost of the box which you'll never user again.
So take it to someone who knows what they're doing.
No. Trying to copy details from another phone will not fix the problem because the IMEI is a unique hardware identifier which is assigned to the particular radio in your phone.

No no, I do not want to change imei! I want to put my imei xD and I think this is not illegal, I tried with my sister's efs only for using an clean EFS folder where I can work, I know all EFS are proprietary for each device.
Anyway the soldering are not a problem, but I agree with first point.
I have another question, on GT-I9100 whitouth imei is possible to put the usb in qualcomm mode? i tried with
su -c 'am start -n com.sec.android.app.phoneutil/com.sec.android.app.phoneutil.USBSettings'

but this has generated an error:
Activity class {com.sec.android.app.phoneutil/com.sec.android.app.phoneutil.USBSettings} does not exist

@diffuser911 Unfortunately, I tried the same as you without success :\ Can you enter in qualcomm mode? perhaps you can solve with NV tool (it is in EFS PRO)...I dunno

Can't say I could :silly: I am quite dumb when it comes to android stuff. Which one did you try, SRS server IMEI repair? I have another guy who claims he can fix the phone over the internet for 10 EUR, google for cvxcvx, Polish site.
Have contacted him, awaiting repsonse.:fingers-crossed:

No I didn't try because in the tutorial they refer to phones with a generic imei and mine have empty imei, I would not waste money if the software don't work.
I hope you solve .
I wanted to try the tool of @lyriquidperfection here: http://forum.xda-developers.com/showthread.php?t=1308546
But I have not found a way to get qualcomm mode

That guy isn't too responsive. Asked him to check if system is accessible via the tools he recommended, he wouldn't budge beyond payment. I am thinking of going the SRS Server way.
Messed up with my G925F!!!
Hello , my phone suddenly was not able to make or receive any calls or joining 3G/4G network or SMS. In other words, I was out of service although my SIM had not problems to enter the PIN password and I could see signal bars.
After a little research I discovered that my IMEI and S/N number had been changed! Especially, the IMEI number became 350000000000006 (fake one) And I believe this is the reason my signal went off!
So , I just managed to download smart switch from samsung and choose "emergency software recovery and initialization -> device initialization" in an attempt to revert it to stock rom and settings (is this method unroot the phone too?)
But after this long downloading finished , the phone didn't boot , I only see the samsung galagy s6 edge logo stuck!!!!
So , I decided to root the phone again , following the guide here (link-->), zidroid.com/how-to-install-twrp-root-galaxy-s6-edge-on-android-5-1-1/
(in short words , I installed the twrp recovery with odin and I flashed 2 zip files required, from an usb-otg-flash drive, via the twrp recovery install button) and then the phone booted normaly , but the problem with the signal and wrong IMEI was still there!
I feel that I am on dead end , I don't know what to do , I am thinking about sending it to the location I bought it but I am afraid that the warranty is lost.
Please help me restore my phone back to normal
After repeating the whole procedure several times , now my phone does not recognize SIM card at all , as if it was never inserted , wtf?

So you mean that there isn't any way of backing up the IMEI number first before rooting or changing a rom/kernel/recovery to the phone in order not allowing this IMEI bricking happen again by means of restoring from its backup?
I googled a lot and some people suggest that they can backup EFS in some way. What is EFS exactly and how it is related to IMEI?
Also wouldn't be a good idea to find a way to backup my entire OS/firmware (not just IMEI/EFS) before doing anything , in case to save money and avoid the same bricking?
And yes , I have sent the phone to samsung service , it will cost me around 320 euros , because they discovered I changed kernel/rooted the device , and they will change motherboard.
I cannot help the phone without being rooted , I love rooting but I cannot understand why suddenly IMEI got bricked.....does it worth to take risk and root my phone again? But I want IMEI or entire OS backups first before doing that and I don't know how to achieve this without rooting first...
Please help me if you could.
You can backup your full os using twrp recovery
Also your IMEI
In SAMSUNG devices imei number stored in efs partition that's why people asking take efs backup before flashing any Rom

Me too! I have the exact same IEMI number! Mine stopped working after about a month. I tried to return to seller no response. I tried to send phone back they would not accept phone, so it is on it's way back to me. Once I get it back I will try what you did.
I have taken it to factory settings 3 times no luck. I will try your process once I get me phone back.
Thanks!

I did contact one of those fellows a reputable one that can change your IEMI. Well once he heard that crazy IEMI number, he said because it was changed once before to something like he doubted he could change it again and save my phone. To try he charges 100 US plus I have shipping there and back. Yikes.
So any advice you can give me I would truly appreciate.
Thanks!
g925f imei repair
new g925f repair method
repair ok
:good::good::good::good::good::good::good::good:
Mine went down recently with the exact same IMEI and no SN. TWRP was failing to restore the efs partition damaging the files in the process. Long story short, I had to manually extract the efs files, copy them across and fiddle about with permissions but I'm working again.
That nugget rings true - always backup the efs before changing anything.
But for that reputable fellow to say that the IMEI had been changed before because of what it had become, and insinuating that the imei couldn't be changed more than once was complete twaddle. I wouldn't trust him near any of my phones.
On a lighter note I'm sure there's got to be a member on here would sort it for beer tokens
Happened to me, I thought it was faulty ROM and all but then I realized it was simply apn setting. Resetting it to default did the trick. It can be found in Settings > Mobile networks > Access Point Names

Since this thread is quite old and people keep answering , I want to end it like this:
Back then I didn't avoid to pay about 300 euros to replace its motherboard to a samsung shop. But I learned lately that the issue was due to an app called "USB OTG Helper" (https://play.google.com/store/apps/details?id=net.shajul.usbotg&hl=en) which allows you to insert NTFS USB flash drives to your OTG phone but also enables a system partition , including EMS files to be visible.
And you can guess what happened next , I deleted this system partition which this app made it visible and yes , my IMEI was gone!!! After some months , I repeated the same delete thing , but previously I had backed up via TWRP the EFS and MODEM partitions. My phone lost IMEI again , as expected , but after restoring EFS and MODEM , the IMEI was back!!
To sum up , never delete files or partitions that look like "system" like bluetooth and imei folders when you are root AND always have a backup of all your rom via twrp or something else before changing/deleting/flashing anything related to your system.
