No it's not so. Revert back to Lollipop and your baseband, imei will be recovered.

I have already experienced this, have been jumping between Kitkat and Lollipop since a week because of the same problem, I guess Lollipop has updated the EFS which makes Kitkat unable to read it properly.

Hope this helped you!

Can't boot into Android

Hey there!

Hope you are able to help with this little trouble: I have successfully installed the ROM following all steps, but when I finished it and the phone booted up correctly, I saw the available OTA for downloading. Dumb me, I tried to install it (before I saw the warning to not to install it) and since it was taking forever, I rebooted the phone explicitly.

Then all it does is taking me to the Carliv menu and there is no way of getting to boot the system. I'm afraid something in the boot section was corrupted with me trying to install the OTA. I tryied going all way down to the installation process (wipe data, wipe dalvik cache, and installing the ROM again) but nothing.

Any ideas for this idiot? Thanks in advance!

Edit: When I was about to fall into despair, I remembered there was a way to restore everything from stock. So I followed from official Wiko website all the instructions (as superdragonpt posted), and I managed to get my bootloader back on track. Tomorrow I'll try again installing the custom ROM, now without even touching the software updates.

[RECOVERY] [ROM] Wiko DarkMoon (MT6582) [MULTILANG]

Hello,

I just installed this ROM and it seems to running just fine! Such a great improvement for my Wiko!

I've been reading through the thread and it seems I should be able to find "Performance" options and be able to open Gravity, but I have no performance options and gravity keeps giving error "GravityBox system framework not responding. Exiting". Some suggested reinstalling gravitybox and installing another cpu app, but I would like to know if that is advisable.

*Is it possible ohter applications might be missing?

Thanks!!

Error when I try to install the rom

Hi,

Everytime I try to install the rom, the recovery said there's an error. This is a little bit weird because I followed all the steps. This is not the first time I have this problem, whenever I want to install this rom (because I tried to install your LeWa OS rom, and it works successfully). I tried to download the rom a second time, but it's the same. I saw that nobody get the same error than me. If you want to know what it says:

And before this, I must to push on "Yes - Install untrusted zip" and it says "E: signature verification failed"

For information, I have the kernel you did.

I hope you can help me, and thanks !

Help Please

Hi Guys

I need you help please.

I tried to do somthing with my Wiko Darkmoon, downloaded here from this forum the Stock Darkmoon ROM and the KIT KAT MOD (found in a thread). Started to see if SP Flash could read some information from the phone (don't know how - Ignored the warning : if you don't know what to do than do nothing) and that was the moment when trouble begun.

The PC I was using was the one I have in my office. Don't know what happened PC interrupted what he was doing.

Now PC doesn't see my device anymore (says unknown USB device) and phone doesn't switch on any more.

What can I do to fix it? Did I ruin my phone?????

Hel please, anyon who can explain (in simple words) what to do???

Thank's in advance to anypone

[One (M7) Q&A, Help & Troubleshooting] professorpasta:
Hi all,

I received a used AT&T M7, described as "not booting up." And it sure wasn't. Stock would simply bootloop. Unlocking and installing CM11 went smoothly, and I was super happy! Until I realized that there was no network connection. My baseband and IMEI were unknown. After messing with this for many many hours, my best guess is that the radio partition is corrupted. And since I have S-On, I have been trying to flash a signed radio. The Guru_Reset_M7_5.12.502.2_clsA seemed to complete successfully, however nothing has changed. More evidence for this is that I needed to SIM unlock, so I tried to use sieempi. It was unsuccessful, with a not found error for cid(?), IMEI, and others (I don't have the exact error right now, but it was common enough that it was autocompleted in Google search). Finally, adb shell-ing when in TWRP, and trying to md5sum the mmcblk0p31 gave me IO errors. I've tried rumrunner, and firewater to no avail. I would consider sunshine, if it was guaranteed that it would fix my issue. It also needed a non-debug kernel, so I couldn't use it in CM. I also can't find the latest RUU .exe for my specific mid/cid: PN0712000/CWS__001.

My IMEI does show up in fastboot getvar all. Reflashed stock as well, same bootloop.

I have hboot 1.57.000, S-On, 5.12.502.2, bootloader unlocked. Any ideas guys?
[One (M7) Q&A, Help & Troubleshooting] nkk71:
If it's not a hardware problem, then running a full RUU could fix it, but since i cant see a 5.12.502.2 or higher ruu (it might exist I just havent checked)

you could reflash the signed 5.12.502.2 firmware zip from [MENTION=2895182]clsA[/MENTION] thread

http://www.androidfilehost.com/?fid=23501681358543602

you will need to relock bootloader since you are s-on

fastboot oem lock
fastboot reboot-bootloader
fastboot oem rebootRUU
fastboot flash zip 5.12.502.2.firmware.zip
[I][SIZE="1"]... wait a few seconds for the reboot[/SIZE][/I]
fastboot flash zip 5.12.502.2.firmware.zip
fastboot reboot-bootloader

check the command prompt output while it's flashing if anything is bypassed

this is what a firmware flash looks like http://pastebin.com/HiA36mBZ

(the SBL1 bypassed is normal, because there are several versions in the zip i flashed, and only one of them works)

Note that the signed 5.12.502.2 firmware only contains the following files:

boot.img
hboot_signedbyaa.img
radio.img
rcdata.img
recovery.img
rpm.img
sbl1-1.img
sbl1-2.img
sbl1-3.img
splash1.nb0

only one of the sbl1-x.img will get flashed the other will get bypassed.

then do a factory reset within stock recovery

finally unlock again, and reflash TWRP + a ROM
[One (M7) Q&A, Help & Troubleshooting] Peacemaker69:
Hi there,

I have also the problem with unknown baseband and IMEI. I try install any stock RUU, Hboot, kernels, radio etc... Doesn't help!

Can anyone give me some commands to maybe wipe or format the partition where the Baseband and IMEI is located? Like a samsung phones EFS partitions? I think that's will resolve the problem...

Waiting for someone to share the details...

[MENTION=4236448]maksmtl[/MENTION]

Use wug fresh nexus root tool. Do u root and reset. And flash lollipop with it. Flash that do a dance... Make a little love while that's going on. Once it's done turn device on have a play log in so on. Tnsfh check your device storage just to make sure nothings gone wrong. (sometimes it shows wrong storage) factory reset from the settings sorts that out.

Shuv usb debugging on and do root and flash twrp (wug does it for you)

Then flash Oct os! Should be sorted.
[Nexus 7 Android Development] maksmtl:
Ooh, that would actually make sense - you have to update from LP and that's why you shouldn't wipe system but only do a factory reset, got it... I already had a LP ROM at some point, but got back to Slimkat because it's still the fastest ROM for me so far. I might restore that LP ROM first, see if that works - if not I'll flash a LP factory image. Thanks for the heads up, will try that tonight. :) F2FS for data and cache should still work with OctOS, right?
[Nexus 7 Android Development] Archtects:

My Nexus 7 doesnt copy anything over from a computer. If I want to copy things to the Nexus 7 I have to do it from Recovery. What happens is that the copied file never copies. It just dies and after like 5 to 10 minutes it gives an error. But in recovery copying works great. Is this a bug or is it just my Grouper messing up. To answer any questions if there are any, I do turn on MTP from the Notifications so it is being recognized from my computer and I can browse the File tree and everything just fine. I just cannot copy to and copy from. Happens on both my Windows 7 and Windows 10 computers. Tried it on my Nexus 7 2013 with Marshmallow and it works fine just like it should. Only happens on my Nexus 7 2012 with this and other Marshmallow roms.

---------- Post added at 10:13 PM ---------- Previous post was at 09:53 PM ----------

I'm having a bit of a strange behavior now when connecting my tablet to my Win 10 PC: when NOT in USB debugging mode it is recognized as Android ADB Interface and it doesn't show up in explorer - when USB debugging is ON the tablet shows up as Nexus 7. Kinda looks like usb debugging is inverted, or could this be a driver issue? Another thing that's a bit annoying is that each time I unplug it and plug it in again, it gets set back to "USB for charging" and I have to reactivate "File Transfer". Is this normal MM behaviour...?

---------- Post added at 10:55 PM ---------- Previous post was at 10:13 PM ----------

Even with micro gapps system is already eating up 93%... Any recommandations to lighten it up a bit? What system apps can I savely delete?
[Nexus 7 Android Development] beeson76:
After messing with it some more, the only way I can copy files from my computer to the Nexus 7 2012 is through PTP mode. Only problem is that it will only let me copy into the Pictures and DCIM folders, but I guess that is ok because I can just use a file manager to move then to another folder. MTP mode just doesnt work. I tried reinstalling drivers and nothing worked. But again in Recovery, I can copy without any problem.
[Nexus 7 Android Development] Archtects:
[MENTION=2264242]beeson76[/MENTION] I had this problem initially. Seemed to work after switching from ptp to MTP. It's a grouper problem/Rom problem the USB connector on groupers are less than wonderful but otg has problems on marshmallow ports it would seem. When I have 10 mins to my self I will run a syslog and see if I can pin point the problem.

[MENTION=4236448]maksmtl[/MENTION] no worries mate, to awnser your first question if you want to change:

To Convert INTERNAL /data to f2fs

Boot into twrp.

Check the box for "data"

Tap "change or repair file system"

Tap "Change file system"

Tap "F2FS"

Swipe the button

Tada!

------

Awnser your second question. It would seem that it's a MM problem from what I can understand all Rom ports have this issue. But I always have usb debugging on anyway so it not a great deal of a problem for me. But again otg connection doesn't work on any Roms atm. So it might be affecting any other usb connectivity.

------

And the gapps are taking up 93%!? Hard rive space or cpu? If it's cpu it might be the browser your using. But I'd suggest gapps, that only have play store and services. Ea :https://www.androidfilehost.com/?fid=24052804347833783
[Nexus 7 Android Development] ruicc:
Here it's working just fine....On Windows 10 build 10586, and octos M rom last build date...all i have to do is choose MTP, pulling down notifications...check if your partition it's formatted in ext4...
[Nexus 7 Android Development] maksmtl:
Hi Archtects, thanks, I know how to convert to f2fs, I was on all-f2fs Slimkat before, which is still the smoothest and fastest ROM that I had so far. :) Only, when I tried it yesterday with OctOS, Android would ask for a password at startup... As for the gapps and system, what I meant is that the system partition is already 93% full, only 7% left, despite having only installed micro gapps, the ones from the OP link. I might try your link, or look for compatible pico gapps...
[Nexus 7 Android Development] Archtects:
Do you have a 16gb or 32gb? If so on the storage page does it say you only have 6gb? If so you need to do a factory reset :) (comon fault with wug root tool and groupers) . But if not then err wow. That's a lot take up. And I can't honestly tell you why that would be?
[Nexus 7 Android Development] maksmtl:
Yeah, I remember that problem. I have the 16GB model, but if I remember correctly I think my storage is quoted correctly - will have to check tonight. Would be interested how much it takes up for others in that configuration...
[Nexus 7 Android Development] beeson76:
How do I do this? And I would assume it would just be the SD Card that I would be worried about?

Now when I am in recovery on one of my computers after about 5 minutes I lose MTP as well, so even in recovery MTP isnt stable for me.

Thanks for your replies Archtects. When you say initially you mean the only way for you too is to use PTP or did you do something to get your tablet to accept MTP.

Thanks again for all you guys help concerning this. I appreciate it very much:):)

===========

Initially I had to use ptp. But after turning debugging on and then going from charging to ptp. Then using mtp and my computer recognized nexus 7 and I could use it. Is odd but does seem to work. I'm running w10 on my pc
[Nexus 7 Android Development] maksmtl:
Ok, I don't know if that's a general MM problem or one with the ROM, or maybe just with my tablet? As you can see in the screenshot, after a factory reset, my system partition still uses 601 MB... Now here's what's interesting: the system partition on my Nexus 5, under LP 5.1.1, uses only 551 MB, while it has more system apps installed. More precisely, The Nexus 7 has 40 apps with 178 MB, the Nexus 5 has 53 apps with only 142 MB... So it looks like system apps are generally heavier under MM, or is it a problem with this ROM and/or the GAPPS? Would be interesting if some other people could report their findings... Btw, I use the micro GAPPS linked in the original post.
[Nexus 7 Android Development] bigmook:
Isn't the os itself bigger?
[Nexus 7 Android Development] maksmtl:
As soon as I load more apps and start to use them my tablet starts to lag again, and sometimes even freezes... Converting data to f2fs doesn't work, it gets automatically formated back to ext4. For now I think I'm going back to Slimkat. I might try again at a later point, when maybe/hopefully f2fs will be supported. Anyway, thanks for all the great work! :)
[Nexus 7 Android Development] Archtects:
Oh right! Idk I only have one 10 apps lol xD. Don't need to many to be honest. Why are apps begin saved to system? I've always used link to SD. And just link them to the storage? I do that on all phones and pads. Does it auto?
[Nexus 7 Android Development] Archtects:
For example. This is my LG g3. With 73 apps
[Nexus 7 Android Development] maksmtl:
New user apps aren't saved to system, they are saved to data. I even moved some system apps over to data, to make system a bit lighter. But still, as I install/use more apps in general, the tablet starts to lag and to hang. Possibly the cache being a problem here? Anyway, since the 2012 Nexus 7 has that problem with cheap flash memory being built in, any ROM I have ever tried, when paritions where formated to ext4, would eventually start to lag. The only one that worked really well so far is Slimkat, with all partitions formated to f2fs. One can argue that system doesn't need to be on f2fs, but even here I could see a difference between ext4 and f2fs.
[Nexus 7 Android Development] Archtects:
I used to have that problem on lollipop but that might have been down to the memory leak. I had multi Rom. And after a day of it being on it used to be so lagged it was unusable. But I've not had a problem as of yet on MM. runs perfectly fine.
