I was waiting to update the baseband until after the OTA rollout once it was available through the LG tool. But when I plugged into USB to do the update, I found out I've got a USB connector issue and I can't connect properly anymore. I've tried enough to feel fairly confident that it's a hardware issue at this point.
I can however connect in APX mode without issue, so I can flash back to stock ROM and recovery. Is the OTA update still available? Seems that's my only option for getting the new baseband at this point.... unless anyone has a better idea?
Thanks....
it might be, i did mine that way at the beginning of June, here is my thread on how i did it, but if your phone is still stock you should be able to go to System Settings/About Phone and click Software Update.

I've read through that thread previously. When I restore back to stock rom and recover, I get an authentication error. Now that I did this, I recall reading something somewhere about one of the 4(?) different model numbers not working over OTA for whatever reason.

hadn't heard about that. there are some stock nandroids out there (2.3.3) that you can flash like any other rom and try those, but then again if its a model number that isn't allowed, then that won't matter
i guess the lg update tool would be the only way to go then. there are some good threads here on how to do that as well. i just couldn't get it to work for me
Hello,
I was trying to port Android 4.2.2 from A83o to A820, which has 4.1.2.
While flashing the files through FlashTool the electricity was cut off. I'm not quite sure which image have been processed the moment of power loss.
when the electricity was back on, I reflashed the stock ROM via FlashTools. Phone turns on and boots into OS, but touchscreen is completely messed up - Top part is bottom now (sligtly misaligned though) and left parts are corresponding to right touch points.
So e.g if I want to tap on the bottom of the screen, I need to touch the display somewhere in the middle of the top half.
It's awful to navigate, but managed to do a factory reset. Not that helped with anything.
I've tried all official versions + my modded roms + restore from recovery. Everything works except touchscreen.
Is there a way to bring back calibration data? Factory menu (volume up + power) is in chinese, but also responds to up and down keys only and I can't select any item with power button.
I can tell people how to dump any block with FlashTool ReadBack option (will give them instructions and so on), but would it be of any help?
PS: Oh, IMEI is not there either, so it seems everything got erased somehow. Not sure where calibration data is stored, but I guess it's on a separate nand flash.
If I flash nvram block frm other A820, will it fix the problem?
I pulled nvram folder with adb and there is /md/NVRAM/CALIBRAT folder inside with many files.
Do I need to replace all of them in order to get it working?
If I get the touchscreen working, then I will fix IMEI and WIFI mac address.
Doesn't help at all. Hardware problem due to power shutdown during the flashing process?
Same problem

I have the same problem on my lenovo a820t. I did a factory reset and still the touch screen is all messy. Did you solve the problem already?
No, I've ordered a new touchscreen, but they sent me the wrong one, so now I'll be waiting another 2 weeks for the correct one

Haven't received my touchscreen yet. It's taking so long...
Still nothing in the BG Post tracking system, which means it has not arrived in Bulgaria yet.
I will report if that fixes the problem as soon as I change it.
I've ordered it from aliexpress, but can't recommend a seller, since I haven't got anything yet, except a wrong touchscreen once, that I had to return and after that they sent me a new one (at least that's what they say). If you decide to order one, make the seller measure it first, so you're sure it fits.
Ok, got another wrong touchscreen from a different seller. And I asked them to measure it first.
They said it's the same, but I'm sure they didn't measure it.
It's one month and a half since I'm not able to use my phone, because of the Chinese sellers.
Now really don't know where I can get a correct one.
There's one seller that seems to sell the one I need, but who knows...
Issue solved, here's how:
This guide applies to A820 only, for A820T you need the first firmware, flashtools and drivers - nothing else.
You also don't need to replace anything, just flash the special A820T firmware and you should be ready to go.
What you need:
1. Special A820T firmware, taken from lenovohome Chinese forum: http://d-h.st/HdW – I have uploaded it in my dev-host folder and removed password protection.
2. Any official A820 firmware, I have used S139 from needrom site: http://www.needrom.com/mobile/lenovo-a820-11/
3. FlashTools - the version included in A820T firmware
4. Ofcourse you need MTK drivers, but if you have flashed the wrong firmware first, then you should have them installed.
- Extract all archives into separate folders
- Load A820T scatter file in FlashTools, turn off the phone and leave battery in. Remove all SIM and external SD cards just for safety.
Now click on preloader (not on the checkbox, but on the name inside FlashTools) and a prompt will pop up.
Select the preloader from A820_S139 firmware (or from the version you chose on step 2). This step is necessary, because phone doesn't start with preloader from A820T.
Alternatively you can replace the preloader inside the A820T firmware folder.
Then hit Firmware->Upgrade and connect the phone to PC.
- After you see the green circle, try to power up the phone. I have tried it on two A820 phones. One of them booted into OS, the other one was stuck at Lenovo logo, but both worked after next step.
- Now turn off the phone again, load scatter file from A820_S139 (or from the version you chose on step 2) and flash the full firmware with Firmware->Upgrade. After that touchscreen should work normally.
Thanks to lenovohome Chinese forums and Russian lenovo-forums.ru. This wouldn't be possible without them.
Note: As I understood from other users, replacing the touchscreen also fixes the problem, so it seems the original assumption that something happens with the controller/drivers is correct.
However I can't explain why and what exactly goes wrong.

No, it just repairs the touchscreen problem. If you flash A820 rom, same will happen.
A820, A820T and A830 firmwares are incompatible. Well, not sure about A820T <-> A830, but both are incompatible with A820.
hello again, now I'm setting the phone and have two sims installed, I have de miui a820t installed with morelocale2, all it's ok but the first sim didn't works cause invalid imei apeears, what can I do to repair it ?

Have you accidentally formatted the nand flash?
Flashing this firmware should not cause such issues. Tried on 2 A820 and everything is fine.
Search for guides for restoring IMEI numbers, there are plenty of these.
I have tried the replace of MP0B_001 file but again the invalid imei message appears, how can I restore on this model ??

Use the method from post #5: http://forum.xda-developers.com/showthread.php?t=2197378
There are some other methods which are permanent, but you can try this first, should work fine if your phone is rooted.
You can get your first IMEI from the sticker in battery compartment, but I don't know how to determine second IMEI without backup. Do you have one?

Same issue with A830
I am also having the same problem with my A830. I think it lost IMEI when I did a full format using Flash Tools v3.1304.0.119. Tried restoring with all 5 solutions cybermaus posted without success. MTK tools show both IMEis that I have restored but phone will not connect. Once it actually worked, I could receive/make calls but it got blocked again within 1 hour.
I flashed another A830 with the same firmware and didn't have these problems. Have also tried several different firmware, but no success.
Very frustrated. Please heeeeelp!

Well, I don't say that flashing a new firmware is 100% safe, sure there is a risk. But it's highly unlikely (if the ROM has correct structure) flashing an official ROM ruins your nvram block. I've flashed offical firmwares for A820 numerous times and I never had such issues.
The problem in your case is called "full nand format from Flash Tools". If you do this, then all is lost and there's only one way I know to permanently restore IMEI's, BT and MAC address. However, I won't post such information here.
I can try to help people on PM, but be sure I'll never post it on the forum.

Hi, I have a similar problem with my Lenovo A820, but it has started without any firmware upgrade or anything I did myself....
I have an area (around the lower third of the screen) wich has erratic behavior : 80% of the time everything is ok, but 20% of the time, doesn't recognize some actions, in particular tap and drag .....
I have followed the Infrared tutorial, but the problem persist. Again, I don't think it's a hardware failure because it's not permanent, but it doesn't seem to have anything to do with the rom installed.
so I have a SR I just put a new (used, off ebay but new to me) motherboard in, and it works fine except for no imei/baseband, so obviously no data/voice/etc.
the efs folder seems to be fine...imei folder is in there, keystr file is there...I don't understand what the problem is.
the worst part is, only certain roms will flash...I cannot flash to stock, I've tried with odin and from recovery, a couple different stock versions of GB, ICS, and still no luck. It actually flashes, then does the "android is upgrading" screen, but then bootloops on the optimizing apps part. I've tried to flash to stock probably 20 times now, wiped everything, fixed permissions, etc...without fail it bootloops every time.
the only roms Ive gotten to flash are slim and jedi...no stock rom will flash, nor avatar and a couple others I've tried. but slim and jedi flash and boot right up...just have blank imei/baseband.
I've scoured threads for days trying to figure out what to do here...nobody seems to have my exact problem, and everything I've found about restoring efs/imei/baseband has involved flashing to stock...which I can't do.
anyone have any ideas?
Have you tried flashing different radios (baseband)?

thanks for the replies...
I've flashed UCM1 and UCLL3 radios, they flash fine but no change...still can't flash to stock and no imei/baseband/service.
That fix thread was one of the first I found, but as I still have my keystr file in the efs folder, I didn't think it would apply to me...I suppose I could make an external backup of my efs, delete it and try one of those methods from scratch.
read through the restore to stock sticky http://forum.xda-developers.com/showthread.php?t=1652398 and go through the trouble shooting sections, if that doesn't help u could have bad hw

Hey, Im facing the exact same problem! just that my imei turned to 0 and basband to unknown after i upgraded to cynogenmod 10.1-rc.2.
It was working fine till suddenly one day i lost network. I tried everything like you did. So far ive had no luck fixing my efs!
What you can do is download QTPS and in it there is a RF NV Item manager to rewrite your efs. For that you need to put you phone into DIAG mode unfortuantely i cant get to that on 10.1nightly cynogenmod that im using.
I m stuck. I know for sure flashing roms or radios wont help at all. the same boot loop problem happens when I flash using odin, it use to work perfectly fine earlier.
Some how the nv_data.bin and such files are missing from my efs>imei folder that contain the imei data.
If you find something please lemme know too [email protected]

will do.
also, you may know this already, but just in case, be aware the skyrocket doesn't use nv_data.bin...I thought it did too when I first started searching around about this, and when i couldnt find it I was pretty freaked out...but then i found out the skyrocket actually uses 3 encrypted partitions rather than a nv_data file. so if you have at least some files in your efs/imei folder you may be in a better spot than it seems. of course if its totally empty, you'll likely have a lot more work to do.
I'll update if I have any luck.

I actually have octopus box as well as the z3x samsung tool installed, however, they're both server activation based...the software is useless without an $89 (octopus) to $120( (z3x) activation.
I'd rather not spend that kind of money for something I'll likely only need once, so I'm gonna do as much as I can in the way of free solutions, and if I have no luck there I'll probably just send it to mobiletechvideos for their $40 efs/imei repair. I'm guessing they use one or more of these repair box programs themselves anyway, and will do the same job for only $40.
thanks for the suggestion anyway though..

There's this polish guy who probably also has all the same boxes and he takes €10 for imei repair by remote desktop.

And finally you could try helping the op of this thread to add compatibility for skyrocket, this would be free.

Isn't there any way to fix my imei on my own ?
Mt efs folder also looks good now with all the files it should have but still the imei remains unaffected.
Also i'd like to know that the qualcom nv tool showed my esn as dead and mied as 000....000 does the dead thing mean it isnt repairable ?
I tried using QPTS but this is where I get stuck.. (img attatched)

People want money for it because it's mostly used for making stolen phones work again.
That means real life risks like fines, jail etc.
Of course there are lots of examples when people experiment with this or that and delete their imei accidentally, or want to change the imei for some other reason. But these are more rare.
An update...
I managed to finally get flashed to stock...still null/null imei & baseband unknown. Efs folder is still there with files, keystr file is on...not sure what else I can do myself at this point so, I guess its time for the Polish dude or mobiletechvideos.

Ohkies.
Did you ask the polish guy about the reason why he was not able to fix your mobile. Coz, I'm just having similar problem like yours. I tried working with all the local samsung service centre guys, nothing worked. One guy said that my mobile IMEI is locked in some database, so it is not picking or detecting my SIM, hence locked. I know that my mobile is unlocked and is valid, I ignored his comments.
I assume you changed your MotherBoard of the mobile with the new cracked SR's, so that it could take new IMEI instilled in new board. Is it so?
Also, please suggest me about any alternatives on how to fix this problem.:crying:

I'm no expert on this, but here is my guess.
There are 2 versions of the Blu Life Play. One of which supports 850/1900 3G bands, the other working with 850/2100. Both of these versions of your phone have 2 sim card slots. My guess would be (and odds are I am not right) is that you flashed the ROM corresponding to the opposite version of the Life Play that you have, and that caused some sort of issue. Like if you had the L100a, you might have accidentally flashed the L100i ROM, or the other way around.
Check the thread or page that you got the ROM from. That 2nd SIM card slot issue might be a known issue. Usually ROM developers will post a "What's Working" and "What's Not Working" section on the thread or page they made for their ROM. Check to see if the SIM card issue is in the "What's Not Working" section.
Hope this helps!

There are 2 versions of the Blu Life Play. One of which supports 850/1900 3G bands, the other working with 850/2100. Both of these versions of your phone have 2 sim card slots. My guess would be (and odds are I am not right) is that you flashed the ROM corresponding to the opposite version of the Life Play that you have, and that caused some sort of issue. Like if you had the L100a, you might have accidentally flashed the L100i ROM, or the other way around.
Check the thread or page that you got the ROM from. That 2nd SIM card slot issue might be a known issue. Usually ROM developers will post a "What's Working" and "What's Not Working" section on the thread or page they made for their ROM. Check to see if the SIM card issue is in the "What's Not Working" section.
Hope this helps!

Thanks for the reply.
That could be a possibility.
I have gone through the thread and I don't see anything specific to my problem but something similar.
I should I have been more vigilant before I flashed.

If it is really necessary that you have the 2nd SIM card slot, just go back to the stock version of Android that came with your phone, and then from there try to get another ROM. That way, even if you are unable to find another ROM that doesn't have the 2nd SIM card issue, at least you will be running a version of Android that does support it.

My main issue at the moment is actually getting the phone back to stock; every time I flash it there seems to be remnants of the old rom.
I cant' seem to get it back to stock.
I managed to get the phone back to stock including the recovery.
I still can't get the phone to recognize the sim.
After reading some threads here I think I flashed a rom for L100i instead of L100a.
I think the problem is to do with the modem.
Can anyone help me please?
I think I have the problem narrowed down to not having a IMEI number.
I have no back up of it.
Is there any way I can get a the IMEI back on my phone?
Phone is no longer rooted and having trouble rooting again.

If all you did was restore a recovery-made-backup, I don't think that will restore original baseband and stuff. If this is how you got back to stock, that means that although you are running stock BLU-Android, you are still using the broken L100i incompatible baseband.
I am not sure if this phone is compatible with ODIN, but if it is and you can find a tutorial on how to restore your L100a back to stock with ODIN then this is what you want. I am not sure what ODIN stands for, but it's a download tool used for not only restoring a phone's android operating system back to stock, but the other things that a plain old recovery-backup doesn't cover like kernel and baseband. ODIN requires a Windows PC with the correct phone drivers installed. So in this case you need the your phone's drivers from BLU on your computer, so that when you plug the phone in it is recognized as a BLU Life. Again, I am not sure if there even is an ODIN image for your phone since generally BLU phones are not that popular on XDA, but if there is then follow the instructions and use that to restore back to stock instead of just using a recovery backup.
IF YOU DO FIND AN ODIN IMAGE FOR IT, MAKE SURE THAT YOU DO NOT MAKE THE SAME MISTAKE OF INSTALLING THE "I" VERSION INSTEAD OF THE "A" VERSION! MAKE ABSOLUTELY SURE THAT THE ODIN IMAGE IS THE EXACT ONE FOR YOUR PHONE!!!!
EDIT: I just re-read your post and realized I didn't exactly answer your question. Sorry about that.
You should do the ODIN thing I mentioned above, just to make sure that you are on the right baseband. However I do not think this restores your IMEI as well. I Google'd how to restore a lost IMEI on an Android phone and got a couple articles on how to do so. One of these articles tells that CHANGING THE IMEI OF YOUR PHONE IS ILLEGAL!!!!! However It doesn't sound like this applies to you according to what you said, because you are only trying to restore a lost IMEI number, not change an already existing one.
Have a look at this article.
Good luck! :cyclops:

All I'm trying to do is get the IMEI that came with the phone back on it; nothing illegal.
Mobile ODIN is not compatible with my device.
I would like to get back to full stock; can anyone help with that please?
I have seen that SpFlashtool might be useful for me.
The only problem is is that I have no experience with it.
Can anyone give me some pointers on how to use it safely?
I'm not sure if people have any interest in this, but I think I have have the problem resolved.
I flashed octarom_kk_iq4410_v3_fixed which seem to give me a baseband then I used SP_Flash_Tool_v3.1328.0.183 to flash a secro.img.
after all that my imei's were restored.
Hi guys
recently bought a s6 from ebay which was frozen on S6 logo. Basically managed to clear cache and factory reset from recovery but that didn't work, anyway I DL the O2 firmware and odin and put it into download mode I get a fail on odin when trying to install the rom
The phone has knox 1 and also has red writing SW Rev. Check Fail. Device: 3 Binary: 1.
I'm unsure what to do and if theres any chance for me to recover.
Many thanks
Mav
it failed because you flashed an incompatible Firmware.
where did it stopped flashing in odin? In sboot.bin?
If thats the case, you need to download proper firmware/country for your device.
Let me know what country is ur fone made of.
Hi thanks for your reply.
I managed to get it working by installing root and unikernel, it boots into O2 the firmwarw is 5.1.1
Only problem now is imei is 3500000000006
And it wont make calls dont know if imei is corrupt ir they sold me a stolen or lost phone?
I may install tw recovery and custom rom and see if that works.
Any suggestions?
Hi
Ive managed to sort out and get it to work infact typing on it now. Its currently rooted custom rom and twrp. I e managed also to restore original imei number so overall im quite pleased with myslef lol.
Anyway one last problem i have is ive tried all sims but none work i know ita picking up signal as the bar shows top right. Also chexk my settings.
Ive tried automatically and manually going to register networks but it says unable to connect try again later. I know uts not my area as my wifes s6 works perfectly. Sim also def works. The phone also picks up when a new sim has been inserted so i dont think its sim slot.
Any ideas guys
OK new update if anyone can help I'd really appreciate.
Installed new vador rom Imei reverted back and serial number is all zeros
Is this something to do with baseband if so how can I fix read somewhere about ariza patch but that was s3 4 etc.
Thanks
Mav
1. Your EFS is corrupted. The IMEI you see is a generic one, phone will be useless for network provider only wifi will work.
2. The one thing that caused this is by flashing an old bootloader to your phone. Thats why youve encountered Check Fail error on Download mode.
Happened to me also but got it fixed in the end.
OK thanks for the info how do I fix? I do have my wife's s6 but that's not rooted and don't want to root can I restore the efs
Many thanks
Mav
Been searching for ages can anyone please point me in the right direction for a fast download of stock o2 5.1 rom? I believe I may need this one G920F_O2U_G920FXXU2BOGC_G920FTEF2BOG1.zip at the moment rapid gator is going to take 10 hours lol.
Thanks
BTW is anyone out there on the s6 forums hardly getting any help really want to try and sort this thanks

I think I know one thread that has a firmware downloader with ultra fast download speed you may try searching it.
I dont know if it will help, but you may be able to successfully flash the firmware but many of those who have problems were unable to boot the phone due to corrupted efs data.
Here's my way of fixing it (if you still have intact efs). http://forum.xda-developers.com/showpost.php?p=63693480&postcount=28
But if its already wiped, there's no way you can retrieve it unless bringing it to samsung or any repair shop.
Anyways, mine was fixed (IMEI) using Octopus box repair tool. Since I cant do anything to recover my generic imei.

As far as i know if your EFS partition is corrupt and you do not have a back up of the EFS partition to restore which you probably dont as you bought this as broken then sim capability is dead, im not sure of any other way to fix this unless you have the intact efs partition
Hi
How can I tell if the efs is corrupt it shows a baseband it now shows the correct ime I
It just won't connect to network it says try again.
I can post a screen print of efs folder on es Explorer if anyone knows what it should look like
Here are screen prints but I think I'm speaking to myself lol
Hi there i spent months on fixing issues like this (i now have a tool that takes care of all this) , best thing you can do is flash to a rom where the original imei came back do a backup of the efs, flash to a orginal rom ( latest rom) make sure its the right one for your device, connect to kies, install the rom again root and restore the efs failing that the imei is blocked use checkmend.com the uk version if your from the uk, message me if you need help

Your rom, recovery and kernel doesnt have to do with corrupted efs.
Only way is to bring it to repair service using box tools to re enter/validate your imei so that you can connect to your network provider. There is no other way around other than retrieving your efs and installing it or thru repair service.
You may now relax yourself at finding ways to connect, I assure it wont help trying to flash and flash and flash stuff to your phone.
---------- Post added at 08:46 AM ---------- Previous post was at 08:37 AM ----------
Uhm can you send sms or make calls? It seems you have a valid Imei
Ok ive tried all stock roms including o2 and a uk btu one but no luck they all do the same thing get frozen on Samsung logo then I flash unikernel and it boots.
When checking my efs folder I can see no modem file I'm now wondering could that be the fault? so I downloaded modem and BL for 5.02 and 5.11 both will not flash via odin I get a fail message and on device check fail device: 3 binary: 1 messgage in red?????.
So I'm a little lost, I was wondering if I managed to root my wifes s6 which is virtually new could I back up her efs folder then copy it into mine and just amend the imei to my original would that work? also is there a way of rooting my wifes phone without triggering knox?
Any other suggestions guys I really don't know what bootloader was on it to start with or rom is there any way for me to find this out?, also another weird thing when the o2 uk roms install they install german apps?
Thanks guys
Ive repaired EFS Partitions with scripts downloaded from links at xda.
For example i trashed my EFS partition on my note 3 so it caused hard reboots after android booted up and it couldnt be fixed with anything else than the EFS partition repair scripts.
Edit: friend repaired his Note 4 also.
Thanks but where can I find these scripts as I've looked everywhere and if I did find how do I go about doing it. At the moment when I try to flash modem and bootloader it fails.
