HI guys,
Something came to my mind and wanted to share it with you...
its how to protect my device after being stolen?
I know there are plenty of apps to find the device( through gps remote activation), to erase the contents and release alerts through different ways.
BUT WHAT IF
somebody had stolen your phone , pull out the battery, then boot it into download mode (3 buttons combination that every one knows), and finally flashed it with any rom by using ODIN ???????
the question here;
IS THERE ANY WAY TO PASSWORD PROTECT THE ACCESS TO BOTH RECOVERY &/OR DOWNLOAD MODES IN THE DEVICE, SO IT CAN BE USELESS FOR THE THEIF ???
i hope u understand my worry here
cheers
I think that's called STEAM. Go search and read more of it in the development section.

sorry mate, forgive my ignorance, but is it an app ?
Unless they can change the IMEI then as soon as it is used on any network it will be locked and barred by your service provider.

but if the developers can restrict the access to the downloading and recovery modes,,,,then its virtually impossible to even change the imei, is it right ?????
The IMEI is hard coded and encrypted in your phone.if you mess with the efs folder and the IMEI over there does not match what is hard coded, you get an invalid IMEI and your phone's network capabilities will be limited.
Btw, steam is a sort of recovery.

For the past half a year, I have been using Carbon rom on my Lenovo K3 Note, and it was fine, until it started slowing down. So, I decided to change it to another rom (Nexus), and the next thing I know, my SIM card is no longer detected.
Turns out, the IMEI was wiped.
How would I go about restoring this?
The things I have done:
MauiMETA = Never detects my phone. Places it into meta mode, but the light never turns yellow. Tried on 3 computers, and had no success on getting it to work. For two of the three, I couldn't find drivers for mt65xx and CDC.
MTK Droid Tool: The option to change the IMEI remained permanently greyed out, and was never given the option to change it.
Official rom: Didn't work. Currently using it, and still the same error (Null). Tried factory resetting it, no change.
Engineering mode: Always gave me an error when trying to enter command, never accepted it.
IMEI.EXE: Everything worked, except the IMEI's never changed in my device.
Have tried multiple roms, multiple wipes, SPFlash, CWM (Even ended up installing it again because I wiped my entire phone with SPFlash), and pretty much every trick I could find.
I need this think working in 12 hours.
EDIT: Problem was resolved with trying "official" roms until one allowed me to update within the rom. The Update that was installed via Lenovo's bootloader fixed it. The finished product was that of an untouched phone; I had to reinstall a bootloader, root, and a new rom.
If flashing stock doesn't help, and you have no kind of backup of where the imei resides, you likely need a service center to hopefully help.
But know that any talk of manually inputting imei numbers is not allowed on XDA, as its illegal in most areas.
Good luck!

So it isn't as simple as entering the two codes under my battery into some location, and rebooting?
I'm currently in Europe, and have no idea how any of that works (Studying abroad).

That talk is not allowed, as I said. Inputting numbers falls under tampering and is illegal in most areas, as I said.
So try flashing stock, if you can. But without some sort of backup, you may be out of luck unfortunately.
Please keep number inputting talk off XDA, or I will need to close this thread. :good:
UPDATE: So, I flashed another "official" rom, which initially didn't work. However, it did give me the option to upgrade, which I did. With that upgrade, the IMEI is back, and my SIM card works.
Thing is, the ROM is almost entirely in Chinese.
How would I change my rom without wiping the IMEI?
Please post the link to download the ROM you used.
I have the same issue and even service centers failed to attempt this.
Thanx and regards

You can easily rewrite imei number using snwriter tool, google it.
Ok, Ladies and Gentleman I need some deep thought processing here for some help with a Motorola Nexus 6. In brief here is what the problem is, a while back when flashing Pure Nexus rom, I experienced a loss of my IMEI. I can restore my IMEI but if and when I do, I lose any 4g and LTE connectivity. The phone functions in 3g with data and phone etc... just slow as molasses but if I restore my IMEI to the one that doesn't show up my IMEI correctly I get back LTE/4g and all works fine also. I've tried going all the way back to the original firmware which was saved to computer and restoring it. Same thing, I have IMEI but no LTE/4g. restore bad efs and get LTE/4g back. I've tried going through all the factory firmware's and flashing by ADB and or TWRP and nothing firmware wise will allow me to restore the IMEI and have LTE/4g signal. If I restore the bad efs and get OOOOOOOO for IMEI when using the *#06# on any firmware version, I regain LTE/4g functioning! I am using Pure Nexus 7.1 now and can still see the 00000000 as a IMEI, if I restore my efs and get IMEI back showing correctly, no LTE/4g signal! My phone can only function as it should as long as the IMEI doesn't show correctly! I have tried just flashing base bands and other segments of any rom and still the problem persist! I have even tried restoring an EFS from another nexus 6 and still no help. It's not the sims because I've tried AT&T sims and Verizon sims from other phones and it does the same thing! I've tried flashing with a sims in the phone and without. Any ideas??? It's like somehow a correlating segment of a file is not being recognized when the correct IMEI is present, like some thing some where in the efs, IMEI, and radio are not taking to each other so to speak, unless it shows the zero's! Brain waves come on and help me out here!!
Have you tried doing a fresh install of a complete factory nexus image? (i.e. entirely wiping the device)

Thanks, and Yes, about 30 different times, using Google developer site original factory firmware, using ADB and or TWRP all the way back to original image, which I have saved as I said in the original post! I don't have a problem restoring IMEI it's just if I do, the phone will not connect to LTE/4g no way no how. I have to have a "0" IMEI for the phone to function as it should actually function and the LTE/4g radio to work, something strange is a miss!

Alrighty, no need to yell.... The factory image is flashed with "fastboot" NOT adb or TWRP. Just wanted to clarify how you were returning the phone to stock.

Yes I said thanks because I was yelling! Jezz, get a grip THIS IS YELLING! ADB/Fastboot both tools are used to flash, extract etc.. with your computer, so obviously one cannot flash/restore etc... without using the proper tools via computer!
Try this:
1) Install "Change APN" app from Google store
2) Open ChangeAPN and click the "option" ( the 3 vertical dots) in the upper right-hand corners.
3) click "reset to default"
4) exit the app
5) perform carrier reset ##3282#
6)If needed: after the phone reboots, perform PRL/Device config update. That's it and you should have LTE data.

Thanks! Ok, Itried that, restored my IMEI, "reset APN to default" Tried Carrier reset ##3282# and it says "NO Cellular Network" even though I am showing my network and 3G. So, I rebooted and same thing, went to PRL and tried to update and it says "update error" but it will refresh!

You clearly don't know the difference between a recovery, the bootloader and the operating system.
ADB is used when the phone is on and is not how you flash a factory image. Fastboot is used in the bootloader and is the proper method of restoring to factory.

So seniority doesn't imply knowledge, which I think you're beginning to demonstrate in this thread as well as in another where I've seen this same strange unnecessarily belligerent attitude.

Look, I came on here to discuss a situation and or problem, which is what I thought this web site was known for, which I havent run into before, in that way not only do I get some help and or suggestions which might help me but help others at the same time who might have the same problem and or will have in the future and find possible solutions! If you don't have anything positive to add to the conversation/situation/problem at hand you are wasting my time, others time and most of all just making a fool out of yourself being childish and immature. Most on here come for solutions not looking to nitpick and try and belittle others like they know everything, which you don't, otherwise you would have given a solution! So you can continue to act like a troll or just leave the situation be and by the way, you ever hear of ADB Sideload??

No, you can use ADB sideload to flash a ROM which requires you to be in the recovery. Standard ADB cannot be used to flash a ROM.

Thanks, I've used both of those methods, I have even tried just flashing individual parts all by themselves to see if just one part would give an error of some kind while flashing, no errors on any flash of any kind, the only difference being that if I read them correctly that on those methods it said to wipe data factory reset in recovery, before reboot, the Flashall bat file reboots automatically into image just flashed, I usually reboot as last command, if that makes any difference, I've even tried wiping then just flashing the new bootloader after a wipe, because it basically acts like a security checkpoint and partition manager, then rebooting and flashing the rest of one of the google firmware versions for the nexus 6.

So was there a solution? The thread just ended. I also have this problem but I'm no where as technical as thewacokid.
But I do know how to follow steps
So I did a stupid and flashed over a single-sim N9600's EFS partition with a dual-sim N9600's, and now the single-sim one won't accept any SIM cards with an invalid/network locked SIM error. I've tried just about everything besides zeroing the EFS (because I don't know how to to that) and so all I can do now is ask all of you beautiful people if anyone could share a TWRP EFS backup from a single-sim N9600 to (hopefully) save mine.
My apologies for being dumb, and thanks in advance everyone.

I'm not so sure you can use EFS from one other phone, but if it works then, what consequences might have the owner of the original phone if there is in question security breach?!

EFS is my phone identify, imei and serial number is in it, if happen to do something illegally over internet, social-media, money laundering or any other crazy things, justice might or will hold me accountable, and is not good idea for me to share that.
But, i think is better for you to check about how to resolve EFS problem, there is e developer who posted one article about to rescue or generate and solve this problem, so check about note edge or note4 as much as i remember.

Fair enough. What's odd is that the IMEI still matches the phone itself. When I didn't know what I was doing and overwrote the EFS partition with the backup TWRP did say the restore failed, and was unable to write, but the devs said seeing that was normal. Could the problem be the modem partition instead, or something?
I saw the Note 4/etc threads about zeroing EFS, but since they're quite old I wasn't sure if those instructions still applied to newer devices and if they would break things further than they already are. Should I make another thread asking about that for contemporary devices or would those old instructions still be okay?

Did you format your device?
Do you have baseband?
If you lost your imei, you can't recover it forever.
Only Xiaomi Centre can recover it.
I'm sorry.
For rooting, you need to unlock bootloader.
Try using a SIM from an operator that does not requires imei.
That's your only chance.

Look. If you don't have any backup of IMEI, Only Xiaomi can fix it by replacing the whole motherboard, take the phone to them with bootloader locked and don't tell them you rooted or flashed anything ( if you did), they will cover the device in warranty.
If you don't care about IMEI and Sim detection, You can flash engineering rom, Unlock bootloader on it as it does not need sim card and flash roms.
I'd recommend the first option, take your phone to service centre if possible.

Yeah, after flashing engineering rom you can flash miui 12.0.4, but that won't recover IMEI either.
My friend is working on an IMEI modify tool, he will by trying it out on his Merlin today.

Neither Xiaomi Centre can recover it.
They just change the motherboard and then send the older to the factory.
