Mtk6582m Landvo L200 nvram issue? - Android Q&A, Help & Troubleshooting

Ok, frustrating issue, reflashed a from to increase the storage capacity but got a bit messed up. Ended up having to use the format option on SP Tools to flash, then reflashed image using edited EBR files to increase the storage. Phone booted again and storage was increased but noticed IMEI was gone so restored that via Engineer tools, mobile working ok.
Then tried GPS, no fix, standard mtk issue I thought so tried to download EPO files etc. but then noticed no option in location settings anymore for EPO on 4.4.2 from. Fine, tried to go to EPO settings in engineer tools but no option to turn on EPO and download EPO button greyed out! If I look at sats via GPS test app it reports it can see satellites but doesn't attempt to fix, left for a couple of hours but still no fix at all.
Tried loads of things, deleting mtkgps files etc. Tried new GPS.conf files, but still no joy.
So I'm thinking it could be an issue from formatting device using SP flash tools. I notice I get the nvram error message in my list of wireless devices even tho I can hook up to my WiFi OK so something is a bit wrong there. Also tried reflashing rom using just the download option on SP flash tools but didn't fix the GPS, it did stuff up the IMEI again which I had to redo which I didn't think a standard download from SP Tools should do? Which again makes me think something is a bit off with the nvram or something else?
So long post but does anyone have any suggestions to try and get the GPS back up and running? I'm pretty well clued up on flashing ROMs on mtk chipset devices, but certainly not dev standard knowledge so hoping someone clever can help me out? Been through loads of the standard mtk GPS fix solutions so looking for some expert advice now?
BTW the rom I'm flashing is a stock Landvo L200 4.4.2 from needrom, I just modified the EBR files to increase storage although tried without doing that but still running in to the GPS problem.
Any suggestions?

Radio and deleting certain parts of a custom rom

I am running Modco 3.0 and installed the newest radio and rebooted theres no sign of it anywhere?? any ideas how i find the radio?
Also i am wondering how do i remove parts of a rom that i do not want.
Yes there is a small guide on this but i dont get how you actually get your phone and pc into the boot and command stage to enter the commands. I can open cmd on my pc and from then on im lost i know i done this before but forget how i managed it.
Anyone any ideas be huge help.
you can find the radio in the phone info section of your settings. there is no app or anything, it is like the "driver" software for your gsm/3g radio, wifi, bluetooth and gps.
to remove apps from your phone which can not be uninstalled you need to set up adb on your pc. it is not that hard actually, try google when lost. anyway be careful, it sounds like you are not really familiar with a command prompt at all. you can render your phone unusable (not bricked, you can repair it be reflashing the rom) when deleting the wrong files, so double-check what you delete, and make a nandroid backup before.

[Q] Swapping internal with microsd bricked the phone

Hello,
So recently I got lack of internal memory(it is only 512MB though) and I tried to swap internal memory with microSD(marked as sdcard2). However, Im noob in this and after changing the lines I understood, that I changed sdcard with sdcard2(swapped sdcard and sdcard2), however, my android system seems to be not working now. I can boot and access settings, but thats all. No menu, no apps, no anything. Empty screen, only settings accessible. I cannot access any files or anything...
What I tried:
- Connecting phone to PC as I have Android Commander program which can browse system files from pc, unfortunately, failed to connect.
- Factory reset. Didnt help.
- Recovery mode - tried all options that are available, didnt work.
The phone is Prestigio Multiphone PAP4300 DUO. If there is any solution to that problem, please help. When I boot to the phone, I unlock it and I get many messages saying com.android.phone, system and such things stopped working. When pressing HOME button, it goes to home, but its empty(empty screen) and tells Launcher stopped working too. All I can do is access the settings. Cant call anyone though.
Please, give me a solution or tell me what to say to warranty service when I will bring the phone to them. Can they recognize that its rooted/that the vold.fstab file is modified?

That looks to be white, but mine is black.
I rooted it only. Havent done any changes to the phone until yesterday - swap the memories.
Thanks in advice,

Hard way to learn the lesson that it's a bad idea to make changes to the system without having a custom recovery and a nandroid backup, hmm? Depending on how comfortable you are with using adb commands and if your tablet has r/w access, you could mount the system, pull the vold.fstab, undo the changes, push back, and set permissions. Can be a hassle though. Did you make a backup of the original file? But probably better served either reloading the stock OS with SP Flash Tools or see if there is a custom recovery / rom to flash for your device.

[Troubleshooting] A-GPS data doesn't download

I have an Acer liquid mini that doesn't download A-Gps files, so it needs a lot of time to Fix
I tried a lot of gps.conf files and many apps (like faster fix ) but every time i try to download A-gps data it doesn't work. I tried with GPS status & toolbox too and re-flashed ROM and wiped the phone but doesn't work yet.
Anyone could help me please? ^_^

Micromax A35 isn't working fine after flashing Stock Rom

My phone was restarting at the logo. Software was corrupted.
I downloaded the Stock Rom from XDA developers, and followed every thread that could help me install fresh rom.
First problem I faced that flashing failed at FDL2.
Then somewhere on the forum I read that unchecking the calibration option in the download tool would help. I unchecked the calibration option, and lo! it flashed.
So, new software was installed. I was happy but that happiness didn't last long.
I noticed that the new software had some problems.
1. Dialer crashed as I tried calling or someone called me. As a result, I was unable to pick a call or make a call.
2. Bluetooth was successful in pairing with any device, but it refuses to receive or send any file. When I tried to send any file, there was no option of bluetooth in sharing. And when tried to receive any file from other device, there was no movement in my phone, while the phone showed the request rejected.
3. Camera clicked photos fine, but there was no preview on the screen. That is, when I opened the camera, it showed every camera option but the screen was black, there was no image of the person standing behind it. And when I clicked the shoot button, the image shot fine.
4. Internet connects, but only the sending arrow blinked; there was no receiving. Therefore, no site opened.
5. SD card, when inserted, mounted with no problem, but I was unable to delete or copy any file from it. I could only read files from it, i.e. installing software, etc.
6. Videos when played, only sound emerged, no video, even after installing MX player.
7. There was no calender in the menu, while I checked the system.img (with the help of Greenleaf_Yaffs-IMG_Manager on pc) that it was included in the system apps, but not installed while flashing.
8. IMEI numbers were changed. Bluetooth and wireless address were changed. Also, I noticed that bluetooth share app was not installed while flashing, though it was included in the stock rom.
Of all the eight problems listed above I could only rectify the crashing dialer problem and IMEI problem.
Using VRoot, I rooted my phone and using system_app_installer I replaced the dialer from the original stock dialer that I backed up earlier. I tried to install bluetooth share, but it only showed successful installation, but it did not appear in the list of system apps. I installed it several times, but each time it installed as if a fresh app, there was no prompt for a replace, and there was no result. Similar was the case with the calender app.
I rectified the IMEI using WRITE IMEI_R1.5.3001. The IMEI were written in the back of the phone so I could write the original IMEIs but I didn't have any idea of bluetooth and wireless address.
But I couldn't find any solution to the other problems for the past 1 month. I searched all over the net, but no avail.
Now, I think this all problem has its root when I unchecked the calibration option in the download tool. If this is the case, what should I do?
Please guide, friends. Desperately need your suggestions.
Thank you.

[Q] bootloader unlock password- Huawei G630-U00

hello,
I couldn't find any other forum to discuss about this version of Huawei mobile phone. I really need help since the last legitimate EMU update ruined the whole system and now my new mobile phone that I have never had a chance to use it is like a trash device... I hope someone here can help me to recover it since i tried all ways I found on internet.
I bought this mobile from China and bring it to Europe. Since I wanted to remove some chinese default software (that wasn't basic software but really annoying), I used an app and rooted the mobile phone. so I removed some of chinese stuff and installed some of good software. Everything worked fine and I tested skype and I had high resolution picture with 8 Mega pixel camera. I tested all its functionality and it was really good...
I noticed that there is a new legitimate update for this OS, since I still didn't have any sd memory, I couldn't have a backup of this old system and this was a big mistake...
anyway... I let it do the legitimate update for EMU... but immediately after reboot, I noticed that Camera and bluetooth are out of functions... so I first thought the problem is with bluetooth configuration but I was wrong since the internal memory was read only and no longer available.
I formatted the internal memory via computer (the part which was available) but no luck... I bought a sd card and changed the storage from internal to external but this didn't help to function bluetooth and camera...
I had a back up from /system/apps and then removed manually the bluetooth.apk and also its odex file. then restarted the system, clear dev cache and tried to install bluetooth.apk again. but I received error message and couldnt' do that. so again I copied those file back to its location.
So bluetooth turns on now, can send signal but for receiving or sending file, it fails, It can also pairs with other device.. So I thought it should be something related to permissions. I again checked the bluetooth permissioin on /etc/permissions/platform.xml and notice they are ok.
I changed the permission of storage and added the external storage to the list and added group storage_rw.
but this also didn't solve the problem with camera and bluetooth.
several times reset to factory mode didn't solve the problem...
I tried to hack the bootloader but I could not unlock it... I sent all information to [email protected] and asked them to send me bootloader password and provide them with all detail information about the device and accepted that the device is out of warrant but I received no response...
I installed "safe system remover apps" and after having backup of Gallery2.apk, I uninstalled it (it is related to camera and all gallery information)... but with no luck I could install it again...
So, I am really hopeless now since I don't know whatelse I can to do... the system doesn't functioning and I need to load on it the custom ROM but the device only can go to fastboot and cannot load the recovery mode anymore and factory reset from the UI is only reset the mobile to fastboot without doing anything else.
I tried to run the factorymode.sh from the device but I receive error messages to access some files such as bluetooth parameters/power
I couldn't myself find this file on the directory that it looks for.
I would really appreciate it if you can tell me any way that I can unlock the bootloader from the device (because outside of the device I tried different applications but with no luck...)
I have a cutom ROM for G630-U20 (not exact version for this device but almost similar) and if I can have a bootloader password I can try this one or any other customized ROM.
I would appreciate any way that you can show me to solve the problem.... either by changing permissions to solve this problem.
Thank you.
