hi
I bought prevents this smartphone, after rooting, I noticed that the connection would jump, after some research I read the router manual for specific devices that the mac address must be in some range of values, so it must be changed on Android .... following the procedure of the lg p500 does not change ... what can I do?
thanks
anyone can help me? please
Help is subject to someone on-line actually understanding your question and having an answer .
I bought prevents this smartphone >>>>> not a clue what you mean no such app on the market .

The mac address for each and every network device is embedded into the device.
So there are 3 possibilities:
The wifi chip in your SGSII is faulty and is telling the O/S the wrong details - send it in for repair.
The Android O/S has corrupted and is reporting the wrong mac address - reset the phone to factory settings (wiping everything) or flash with a wiping ROM. If still unresolves send in for repair.
The phone is stolen and you are trying to hide its true identity from being traced - no help from this site.

Dear All,
I have come across several threads regarding the IMEI null issue and have seen solutions but most of them dont actually work except where Z3 box are used to rewrite the IMEI.
Some threads I have seen that another similar device is required to copy the IMEI from 1 rooted device to another rooted device via FileExplorer, but nobody has mentioned the next step as to how to set the IMEI null device's IMEI back to its original after copying from another device.
Please let me know as I have 2 rooted device both of which are mine.
Both devices are GT-I9505.
Thank You
Appreciate your support.
Hi everyone,
I come to you as I am a noob as far as twinkering with my gt i9300 goes and I think I messed it up big time.
Here is what I did :
I had android 4.2.1 on my gt i9300, the stock rom from sfr (french career).
I network unlocked it using my career official unlock code, which worked great. It recognized my japanese career sim very well (i am in japan now).
Then I got greedy and wanted to update my android version so I downloaded a 4.4 android rom from I don't remember well, and a cwm manager.
The network unlock worked fine at first but after a restart it did not work anymore. It asked me for a network unlock pin.
I thought it was asking for a sim pin at first, which my sim did not have as I hadn't set one. I got mad trying sim pin code and gave up. Had I given it the network unlock code instead of possible sim pin code it might have worked but I will never know.
Then I tried to solve the problem installing android 5.1 cyanogen version but I had the same problem except this time I understood it was asking for the network unlock code. The problem is that when I fed it to him, it did not work, the request was unsuccessful.
So I looked for a solution on internet and found all kind of things:
I read about restoring the efs partition, but i do not have any back up.
I read about installing a stock rom version, change the csc and retry the official network unlock code, but it does not work, whether I restore through Kies (which gives me a vodafone version) or manually (with an sfr version, french vodafone it seems).
I read about installing Galaxy simunlock app after rooting the phone and installing userbox, but it tells me that my locking system is not handled as it is too new.
I upgraded, downgraded, rooted in every possible way but nothing works.
I am running out of solution and I therefore turn to you for help, hoping you will be more creative than me.
I have the official network unlock code, the phone, no back up of any kind and really little hope.
Thank you in advance for any help you could give me !
Have a nice day !
Sadly you didn't make a backup of efs. That should be first thing before playing with customs.
Oh well, I suppose your efs may be screwed up due to entering couple times bad network unlock key.
I suggest go to next corner GSM shop and pay 2400JPY for efs fixing and perm sim unlock. But before that, check your IMEI and serial number are correct. Thay can fix all of this in one step.
You need to do this via box, you can't reprogram that or fix yourself because you did everything that may help and you still have a problem. You can't use any software on efs v2. It will not work.

Thank you for your quick answer !
I will follow your advice and go to a "professional".
However I don't understand how they are able to do what I can't, do they have special softwares or anything ?
I would like to know because I do have the official unlock code.
Also, I would still like to upgrade to android 5.1 cyanogen version, do you think it will be possible after such a modification ?
I should not encounter any risk if I backup the efs beforehand right ?
Thank you again
Service will connect your phone to, so called, box, ie Z3X Box. This is some kind of pc-phone bridge hardware which can alow to decrypt and encrypt efs files, fix IMEI, serial number, flash firmware, IMEI certificate, remove network locks, sim locks etc.
Of course you can backup your efs now but it is corrupted and useful. Backup this partition after repair. Than you will be able to flash anything you want. Even CM12.1,no problem.

Ok I understand better now.
Thank you very much for your answers, they have been really helpful !
Do not let them plug your phone to the box if you want to install 4.4 or 5.0 because if you give them they will replace your imei number with a clon imei number and you will stuck with max 4.3 and you need to install a patched modem and kernel every time you format your phone... tell them to try to fix without replacing your imei number first. Replacing the imei number should be the last thing to do...
Why do you think they will clone his phone's IMEI? It's even illegal.
If someone doesn't know how to use box than he should not work in GSM service.
You can rewrite original IMEI and serial number without cloning anything.
An probably IMEI is fine, it's network lock problem.

Most repair shops dont care its legal or not. Also most costumers dont know this kind of things and as long as phone is working its okay for them. Mine is just a warning to make him look like he knows this things so repairman doesnt do something with no going back...
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.

I have an efs backup done just after unlocking. If you absolutely want your phone revived I can share it but I guess it will have my imei and mac. I don't know if you can change it but your device might work as a phone. Do tell me if you acknowledge the possible problems then I will give the backup qcn file to you.

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

Can you give me efs file? thank you very much.
I've bought that cheap chinese device, is ""branded"" as D35 pet tracker, unfortunatly it does not work but I think that it's a configuration (APN) issues and not a device fault.
From the beginning:
- The device does not connect via gprs but is possible to call the device
- Connected to the PC is recognized as a mediatek serial device, after some tries i've found that it responds to AT commands, unfortunatly not all... And unfortunatly not the ones that are gprs (2G) related...
- After some search I've found that the board is a Gainstrong Oolite S1 (Based on MT2503), I've contacted the manufacturer but at any question the answer is a brochure of other products (why I'm supposed to be interested on the new S3 board if there is no support for the S1)...
- That board is suitables/used also for smartwatches so that thread can be also usefull for who get that cheap devices
- Following threads for similiar devices i've read that manufacturers changes/personalizes/delete default at+commands and the only way to get that is by unpack firmwares ("d35" manufacturer is unknown, board manufacturer does not give answers )
- Following the steps on another xda thread i've succesfully extracted the firmware :laugh:
- NOW, how can I decompile/unpack the obtained firmware files? Has anyone heard about custom firmware for that board?
Thanks
Set APN with command "APN,apnname,username,password#" (send by SMS without quotes). Username and Password are optional.
Hi, I know this is an old thread, but did you manage to get your D35 tracker working. I am struggling to send the APN settings.
Thanks
Hi, i have bought G977N and later came to know that its IMEI is tampered to get registered on the local networks. it was working before i upgraded it to G977NKOU4CTG1, the original firmware was G977NKSU2BSL7. After upgrading it did not register any of the networks. Got it checked from software expert he told me the network patching done with tempered imei was damaged and now there is no way to do it again on new version G977NKOU4CTG1. I tried to flash G977NKSU2BSL and also the factory firmware of android pie but ODIN get stuck at BOOT.img and download screen shows non-supported version. Can any one help to restore my original IMEI and will it work.
The IMEI ( read: International Mobile Equipment Identity ) is a unique numerical identifier ( 14-17 digits ) for every mobile device what helps to differentiate each device from one another. If you take your phone in for repair, they will track it using the IMEI to distinguish it from the other millions of phones, for example.
IMEI basically has nothing to do with phone's local network settings at all. But it may be used to unlock a phone on certain networks.
The IMEI is stored on phone's /EFS partition and/or /EFS folder. If you didn't backup that before flashing you have lost, IMO, unless you still have the box in which the phone was delivered, because there is usually the IMEI printed, too.
I don't have the box of the phone. The seller has tempered the imei to get it registered on the local network. I didn't backup before flashing. Now what to do. How to downgrade to previous firmware. I tried to flash the previous firmware but it stuck in boot.img.
They told me solution is available for U3 binary but no solution is available for U4 binary.
Awaiting for help on this issue.
You should have returned the device. Since the imei has been tampered with you will not get much help here. Imei changing and tampering is illegal in most countries. And it's not discussed on xda

I'm guessing you also bought a tampered IMEI device. Take it to any local market where there are plenty of phone 'software repair' guys. Ask them if they have Chimera or z3x tool. They'll fix your problem for ~800 PKR.
Remember, if you buy such devices, don't flash anything on them. Every time you do, you'll need to go back to the same software guy and pay him to fix your signal issue.
=========================
For other people reading this comment - Yes I understand IMEI tampering is illegal in most countries. The reason people in Pakistan buy these phones is because the government has levied unreasonable duties on all imported devices, without any consideration for the age/condition. For example, a used/refurbished S10 that costs you 250 USD in the US, will have custom charges of about 250 USD applied to it if you want it to work in Pakistan. So basically you pay double.
I have this same issue somtimes the signal comes and somtimes it doesnt.
