Lenovo P780 - IMEI lost - need valid MPOB_001 Hello,ĭumb as i am, i flashed a new Lenovo P780 with a ROM from without making a backup first. Did you guys resolved this issue earlier? Any help, greatly appreciated!!!
I am facing EXACTLY the same issue for a lesser known brand (iOCEAN). I was wondering how you finally got to fix urs. If you have, you must press ROOT button first to change IMEI and restore NVRAM.bin from your stockROM If I am, then how can I get nvram.bin file for my phone?Ĭan it be generated from BPLGU file somehow?Īs you people can see that I have tried a lot of things, so please suggest/advise accordingly. So I think the only way out for me is to flash a nvram.bin with SP Flash Tool.Īny ideas whether I am on the right track or not? only modify IMEI when baseband or radio files are already present on the phone. Probably SN Write Station and Maui META etc. It does contain a BPLGU file but I can't seem to modify IMEI with SN Write Station or Maui META etc. Now the official firmware of Primo F2 does not contain any nvram.bin file. So the phone has no baseband or radio files right now. I am sure the problem is that when I formatted the phone it wiped the NVRAM region too. When I try to fix IMEI from MTK Droid Tools it shows 'ERROR : pttycmd1 device NOT found!'.Īlso, MTK Droid Tools shows 'Baseband v: -'. Now the phone works fine but it does not detect SIM.Īlso, the IMEI is shown as 'Invalid' for both SIM slots when I input *#06#. Then I flashed the official firmware of this phone with SP Flash Tool. If this is a right file it will take sometime to load.SIM not detected, pttycmd1 not found, NVRAM empty - Questions and Answers I 'whole formatted' my MT6572 based Walton Primo F2 phone with SP Flash Tool. On this dialog there is a button for loading “nvram”.Ĭlick it and load the file downloaded from link provided. Select “change or write imei” from the dropdrown menu.Ī dialog box will open for entering new “IMEI” number. So next time when you are able to get Maui Meta tool to recognize your phone, then 1. Here is a Google drive link for it I saw your comment that you are sometimes able to connect. Anyways I have managed to recover on file from my crash system, not sure but hopefully it is the one. I had bookmarked the site but it is lost due to crash. This is a very rare database file which I think I found on either Chinese or Russian site when I fixed my device. Anyways what I remember is that you need correct modem database file to fix IMEI for K4 Note (MT6753 chipset). Since then I too am struggling to get Maui Meta 3G to detect my smartphone.
Hi Nik, Unfortunately I had a system crash last week and lost all the working drivers and other important files 😦 unfortunately I didn’t had any backup.
I am hoping that i I will be able to fix the “serial no” issue with it. Is the nvram.bin file you have provided is a raw file? When I tried to load it into flash tool, it complained that there is no header for the bin file and the process stopped For everyone: Can someone please share an original nvramp.bin file for Lenovo Vibe K4 Note.
What is the difference between nvram.bin file and modemdb and apdb files that comes with stock ROM? I am able to fix my invalid IMEI problem permanently using Maui Meta 3G tool but the serial number is still all zeroes.
If I do not have a back of nvram.bin, then where can I download it? Does it not come with Stock ROM? I have Lenovo Vibe K4 Note powered by Mediatek MT6753 chipset 2. If you or anyone can answer them I’ll be very greatul. Hi, great tutorial! Though I have some questions. You have the correct nvram backup, you can give a try and confirm 😉 Thanks. I haven’t found any confirmation of that on the net. MTK Droid Tools can’t be used with new 64bit processors (mt67xx).ĪFAIK the only chance to obtain a nvram image backup from mt64xx device is to make a flash tool “readback”, but i don’t know if this is the same image of the one obtained by MTK Droid Tools and if it is (successfully) flashable back again with flash tool. So this procedure is only verified with mt65xx chipsets. Congratulations 🎊!! NVRAM restored & IMEI permanently fixed.Now connect your phone w/o battery 🔋.Deselect all files and select only nvram.
If you don’t have nvram.bin backup then 2. Can anybody help me? I have no backup and i can not find flash rom file for this version. Normally we refer people to this post, as the procedure is mostly the same.
