Hello,
first of all, i have to say i am googling around and found nothing, exept how i use a scatterfile etc.
My problem:
After flashing a custom cwm with spflashtools to my jiayu g2f, i got the nvram warning under wifi.
This warning comes, because wifi/bt MAC is random and IMEI is lost.
This is reproducable.
So my question is:
All tutorials said, flashing a custom cwm with spflash is not a problem:
just select modem db file and scatter, select only the recovery and change the file to the custom one.
I take the custom one from needrom. It works, when
flashing via mtk droid, but when flashing with spflash, i get the nvram error.
I recognize, that the size of the file is another than the original size in the official rom. Isnt there a need of editing the scatterfile to fit it to the new size or is the recovery area on the phone big enough?
Today i make my own cwm via mtk droid tools and i flash it. Also with this, i am able to reproduce the nvram error.
For me, it is only possible to write the IMEI and WLAN MAC and BT MAC back with SN Station writer. All other tools
will fail on my device.
Thanks for reading,
Nine
Hi,
after ROM flashing (ROM that was working fine for me earlier - MIUI V5 5.1.30 , Android 4.2.2 )
i started to get this in recovery :
unable to mount /emmc
unable to mount internal memory
unable to mount /data
+ i cant even wipe dalvik cache.
after first boot, the ROM is stuck at boot logo ( MI logo).
I thought its a bad flash so I flashed a ROM that I got the phone from dealer with (MIUI 4.4.25). Phone turned on, but the IMEI numbers are gone.
When I run Mobileuncle tools / Engineer mode , the CDS Information option is greyed out, its not active.
So I wanted to recover the IMEI via MTK Droid Root & Tools . But when I plug in the device to the PC, the PC doesnt recognize it.
Also, my phone doesnt recognize the SD card (in the OS, in the recovery its everything OK).
Can you help me with this?
THANK YOU

flash it back with original firmware using sp flash. dunno with IMEI though if it will come back.. but start from there.. after that root and go to mobileuncle to restore your IMEI.

Hi. What MIUI did you flash ? What version ?
What you have to do is to enter again in recovery with vol+ vol- and power button pressed all together!
Wipe everything except SD Card!
Remove your SD Card and go to some laptop or PC with SD Card reader, copy your old MIUI on it.
After copy and wipe go to your phone and insert your card.
Start your phone directly in recovery and now your SD Card should be recognized by the phone.
Reflash your old MIUI.
Good Luck.
Tell us if you have problems!

i cant. the recovery isnt mounting emmc, data, internal memory.
that will be a big problem if phone cannot be detected on sp flash tool anymore. make sure phone is turned off and the sp flash is waiting for your device after you insert cable to phone.
i made some progress, MTK Droid Root n Tools recognized the phone.
i should be able to flash the stock now, right?
EDIT: I managed to flash S135 (130917) - stock chineese rom and internal storage, USB storage, SD storage - all seems to be functional and loaded. So this issue seems to be figured out.
EDIT: flashed desired MIUI 4.4.25 Multilang via CWM, all storages operational. Im on fixing the IMEI now.
--------------------------------------
EDIT: I cant restore the IMEI.
I tried imei.exe trick. No change.
I tried engineering mode / Uncle tools - in MIUI i dont have access to CDS Information, in stock ROM I do, but experience a "failed to send" response.
I tried MTK Droid Tools - i type in new IMEI, i reboot via the programme and after reboot the IMEIs are still "null"/"null".
Im desperate. Any help?

This is bad... Your NVRAM is erased! Look on /dev/radio/ and tell us if this radio folder is empty!

looks like i need to restore hard-IMEI, this is my case:
NStorm said:
They guy clearly told he is able to restore MP0B_001 in phone, but its SOFT-IMEI and is lost after wipe/factory reset.
@ Original question by ToldarkenHansam, which is kinda outdated, but considering lame answers here:
To restore HARD-IMEI in NVRAM hidden partition use SN Write Tool or Maui META 3G. They are able to write hard IMEI and calibration to NVRAM partition.
@ kokabunga - if you have nvram.bin backup you can easily resore it with SP Flash Tool. Just open your scatter file with any text editor, find a __NODL_NVRAM section and remove __NODL_ part from it. Reopen scatter in SP Flash Tool and you'll be able to check NVRAM partition.
It might not be able to upload it without other parts selected. But you can you Options->Write memory, then manually enter start address, which will be show on download/upgrade page near NVRAM and length (your nvram.bin length) - that will always work. Be careful to write correct address thou.
Sidenote: all suggested methods before only touch SOFT-IMEI, stored in /data/nvram/md/NVRAM/NVD_IMEI/MP0B_001. Its lost with any wipe/reset, because whole /data partition are formatted. Then the whole /data/nvram directory (if it's empty) are restored from hidden NVRAM partition on EMMC. If you've corrupted your NVRAM when it won't restore correct IMEI ofc. With all methods mentioned above (i.e. replacing MP0B_001, echoing to pttycmd1, using mtkdroidtools, mobileuncletools and others) will only edit MP0B_001, i.e. soft copy of IMEI, which will be lost again with next hardware reset. Sure you restore your IMEI that way every time you wipe/reset/upgrade firmware. But its more solid to fix your IMEI partition with SN Write Tool / Maui META 3G so it will be correctly restored automatically from NVRAM at every wipe/etc.

but Maui META 3G isnt recognizing my phone, though it starts a meta mode automatically. SN Write tool itsnt working as well.
Thoughts? Is it possible to flash just a nvram partition? When I try my SP Flash Tools get a 8038 error.
i found a nvram.img for p780 from someones backup on the web, so i tried to restore it via adb, i got this:
edit: OK, the batch file runned succesfully ( its the utility nvram_backup_restore_wo_root-shell_3.7z , stympy, you posted it here in one thread )
what shall i do now? the IMEI are still invalid after reboot.
put the nvram.img to your sdcard not on your computer. and try the batch file again.. I tried that before using that image .. it did not help restoring imei... try it maybe it will help you
Hi all. For those of you who flashed wrong firmware and your IMEI are gone look what happent to me:
1. i flashed a custom recovery who errased my IMEI. That happent because the recovery was 7.5 mb instead of 6 and i was "blind" and careless and stupid and...nevermind
2. after restart surrpriseee.. no IMEI.
3. allmost total panic here.On MTK Droid Tool 2.5.3 IMEI NULL paniC again, and my worst nightmare PTTYCMD1 ERROR FILE NOT FOUND. Panic panic panic, used hard words #@$^%&(&&%$%& words alot.
4. after a little cooling i reflashed my old TWRP back and started to look in my computer for the firmware i allready have installed wass Baralajbi v6 (i like the partitioning of internal memory) firmware from needrom. Before that i tried to restore the NVRAM from TWRP. It did not work. No IMEI has appeared after restoring with TWRP.So i have rebooted the OS back and i immediatly go to /dev/radio where the PTTYCMD1 and the folder was empty.Again *&^%&$%^#^%#%^#^&(*(^* words.
5. Then i have reflashed Baralajbi firmware and after flash i have installed Root Explorer. Again i immediatly go to /dev/radio where the PTTYCMD1 and the folder was this time all the files were there.
6. So if this file PTTYCMD1 is in the /dev/radio folder you can restore your IMEI safely with any tool.
7. I hope this little problem of mine will help you other users to restore your IMEI.
I flashed different recovery (6mb, cwm) and different rom (miui 4.4.25 multilang).
I managed to get this... (But all of them have 0 size). Is it good?
I tried to use mobileuncle tools, but the option i need is still greyed out (wonder if miui blocks it out? on stock rom it was accessable)

You must try to flash a stock firmware CN or ROW.
MIUI is custom firmware.
The firmware must be flashed with SP Flash Tool.

Hello everyone , on trying to upgrade my alcatel v860 to a cyanogenmod 7 system , i had to delete the system partition and custpack partition because this new zip file will replace those current partitions , however i had an issue .
I have the boot , bootloader , recovery & data partitions still active in the phone , i know this because i did not erase those partitions , however since my system partition do not exist and possibly fastboot makes a call to phone /usr/bin files for the upload , i am stuck in the logo of android and i am unable to upload those partitions because right now my windows do not recognize the phone driver .
On fastboot i had android 1.0 driver , but know it turned to unknown device .
After a few looks n the web i realized that the driver that i need is the broadcom usb to serial driver , witch i have here , but somehow it is not installing correctly and right now i have no idea why is that happening .
here it is a picture of the installation .
https://s14.postimg.cc/8mavyxu2p/vodafone.jpg
Does any kind soul around here with time and patience to read this topic in millions of others experience this ?
Is there a way to solve this issue without much sweat ?
If the only solution is jtagging the phone then where can i find the schematic on the phone pins to do it ?
Note : this phone is not in warranty anymore , so send it to the provider is out of subject .
If you have read this topic until here , i thank you .
Best regards to everyone
I discovered that the broadcom to serial driver that i have here with the correct VID for my phone works in XP and i was trying to install it in W7 64bit .
So , the best way is to create a Vrtual XP machine for this issue and add the phone usb port (identifyed as Broadcom) to VM config so the XP can detect it .
i accidentaly flashed my leagoo z6 with the wrong wrong firmware and hard bricked it using sp tool i was able to recover it but i lost my nvram and nvdata files since i had not bucked it up av been tryng to recover from this but i am stuck since the phone cannot get rooted and cannot install twrp. it is becoming more deficult to solve the problem without root permission which i have tried to place through many way but failed. i have tried to use adb sn write tool imei generators mtk engineering tool to no success. every time am using my pc i keep getting errors with preloader drivers which i have changed severaly to o avail my phone keeps disconnecting with pc hence i cannot work with it can any one give me a link on where i can download nvram and nvdata files or how to make one or help me wit there backup so that i can flash them back wth sp tool which seams to be the only thing working with my phone phone is leagoo z6 mtk6580
