Frankenkaiser error

I managed to brick my device real good. When I start the device, holding down green send, and run mtty to run the dload command, I get Invalid command : dload. Im in deeper than I bargained for. Whats next?
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] DaveShaw:
What did you do? task 2a?

Are you security unlocked? What SPL do you have?

Thanks

Dave
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] xerootg:
I have a KAIS130, SPL 1.0.olipof, task 2a. security unlocked.
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] DaveShaw:
Hmm, if you did a task 2a you probably no longer have an SPL ;)

Just use FrankenKaiser to restore the SPL. If you have a problem with it, post in that thread (I'm subscribed :))

Dave
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] xerootg:
Thats exactly the problem. I cant get the kaiser into dload mode.
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] DaveShaw:
Do you have the MotoQ drivers installed?

Does your phone make a "ding dong" sound when you put it in OEMSBL and connect it to your PC?

EDIT: Why did you do a task 2a in the first place?

Dave
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] xerootg:
The phone does not make a dingdong sound, I am using the MotoQ drivers.

I task 2a'd because I am having extreme radio issues, when I (task 6?) I noticed I had many reversed blocks. I figured I would be able to reflash the SPL right after I task 2a'd but it stoped responding before I could reflash it. When I rebooted it I got a green status LED and no screen. When I plug the kaiser in, I get the 3 data devices.
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] DaveShaw:
I meant "PC", sorry.

I really arn't dure why your phone won't go into download mode. Maybe GSLEON3 or jocky2001 can help.

P.S. Merging this with the FrankenKaiser thread.

Dave.
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] gsmactive:
This firmware provided on the front page does NOT work on NIKEs (dispite of what it says). However, the idea behind the process is sound.

Here is how you go about fixing a NIKI in OEMSBL.

1. Create a .nb from a NIKE hard SPL package. (for example hardspl-1.5mfg-nike). Use the NBHextract.exe to extract .nb from .nbh

2. Follow the procedure outline on the frontpage, but instead of SPL-1.56-KIAS-unbricker.nb, use the .nb created from step 1.
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] Galileo911:
Hello how can i know if my pda is unlocked? I have the same kaiser of DaveShaw
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] DaveShaw:
What sort of unlocked?

So you can Flash ROMs?

-Put your phone in bootloader mode and tell me the SPL version.

So you can use SIMs from another network?

So you can use Franken Kaiser?

-http://xdaforums.com/showpost.php?p=2590275&postcount=2

Unless you're phone is already bricked, in which case it may be too late.

Dave
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] Galileo911:
In fact...my pda is bricked...i have used mtty and the task 2A. nOw the only think that my pda does when i press power on is a black screen and the green led. I have red all the post of the thread about task2A. Can i hope to save my pocket with franken kaiser?
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] DaveShaw:
The you have no way of knowing if it's locked or not. Only way is to try, you've nothing to lose now :)

Dave
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] Galileo911:
Sure? XD i was thinking the same think when i used task2A XD ok thank you very very very much. Only a question: what is send grey key? it's the botton over the botton with windows image? Sorry for my bad english...i'm italian :D
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] DaveShaw:
The answer call button (I wondered that once upon a time as well ;)).

Good luck.

Dave
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] Galileo911:
Thank you! i'm going to post what will happen
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] Galileo911:
Nothing. PDa is not able to enter in radio boot mode :( and now?
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] DaveShaw:
Do you know what Radio you had? I'd PM jocky if you didn't have the "Radio from Hell" and see if he can help.

Dave
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] Galileo911:
i don't know it... the only thing that my pda do is to be detected by pc like a modem.
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] Galileo911:
I'm a noob XD
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] Galileo911:
The last ROM that i tryed to install is TiR v8.
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] Galileo911:
After 5 months in assistence they give my pda like 5 months ago!! bricked!! Please Help me :( what could i do now? :(

I've read a lot of posts regarding three color screen, task2A, Frankenkaiser. I've installed MotoQ drivers, phone is detected by winXP, drivers are properly installed (it's on COM4, 115200 bps). Phone is responding at some MTTY commands, like "setboot" "radata 9000000 1" (found in Frankenkaiser SPL1.56) but not at "dload" "echo_on" "mw ..."

I've tryied to flash like in "Radio Hell from Kaiser" but obviously stucked at step 6-7 because i've not this radio installed. So i tryied to follow this post, but i'm still stucked after doing Frankenkaiser command at prompt. It says it has correctly uploaded the SPL but when i replug or reset (holding green button) the phone, and load MTTY (1.42) and do "mw .." command, it says: "Invalid command : mw"

so, the phone seems to be bricked, but not broken :P

it answers at some commands, but im not able to complete any procedure to the end.

Any help or idea about how to solve it? Thanks a lot

***** EDIT *****

It seems like my kaiser is not unlocked, because http://xdaforums.com/showthread.php?t=369754 it accept only the locked device commands

there is a way to let me know if it is locked or not? I buyed it few months ago with SIM unlocked and modified ROM - RADIO - HARDSPL installed, so i thought it was unlocked, but i did not unlocked it by myself so im not sure it was.. :(

damn i like Kaiser so much, i hope it could revive soon.. tnx for help again
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] mharrissmith:
Snooze options

I have just flashed your ROM (M2D,85Mb,2G) and looks great! One thing, is there any way to have the option of snoozing an appointment for a certain period of time? It looks like is is set as default at 15min, sometimes I need to snooze them for 1 hour.

I know there are some CABs to fix this, but i want to know if you have tested any of them , because apparently many of them won´t work.

Thanks!

[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] thebulletfromhell:
NO!!! For one thing, doing this for a noob will f*ck your device. Try hardreseting first

[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] nicke85:
I have installed Qmoto drivers..but when I press green poone button and connect to the PC then enter to mtty142 and type "dload"..

Depending on how well this rom works I might just unlock my phone today. Does it have bugs? If so what are they? I'm willing to try it as long as the features I need work. Even if something is broken
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] theimpulson:
Links for official build has been added in thread. Have fun!
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] theimpulson:
Stable enough to be called as a daily driver I guess. Been using since few weeks, no issues. (Remember I am OP :P)
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] zeft64:
Okay bro. Well looks like I'm going to pay for this bootloader unlock then. Plus it's pretty dope that you gave us adaptable storage. Thanks man!
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] atmin:
Can't use sd card.system can find the card, but the applications can't find it.
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] zeft64:
I forgot how to do it but edit your post and mention the dev so that he can see this and fix it. Also include a logcat. If you don't know how to do this you can look it up on YouTube. It's pretty easy.
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] Mimsly:
Thanks very much for your great work on this ROM.

I am trying to install this ROM but receive:

"Failed to mount '/firmware' (invalid argument)"

This is what I did:

Unlocked bootloader.

Boot into TWRP.

Wiped partitions and format data and internal storage partitions.

Slot A: install OmniROM and Community Vendor.

Switch to Slot B: install OmniROM and Community Vendor then Wipe Dalvik.

But TWRP gives these errors when installing ROM and Vendor on Slot

"Failed to mount '/firmware' (invalid argument)"

Is this normal to receive this error on Slot B?

And in TWRP if I go into the Mount menu it won't let me select Firmware (if I am in Slot B).

Is it possible to mount /firmware on Slot B?
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] theimpulson:
Never got this. I hope you are using my TWRP from here. Just to make sure, I will repeat steps.

- boot into TWRP

- Wipe everything, format data afterwards

- Reboot into TWRP, flash vendor and ROM package

- Reboot into TWRP again but on other slot this time and flash back vendor and ROM package.

- Flash GAPPS if you want them else reboot into system.

Always use fastboot to change slot (`fastboot --set-active=a` for example) and adb sideload in TWRP to install any zip you want (`adb sideload omnixxxxx-2019xxx.zip` for example).

Great Job bro..:good:make it monthly
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] atmin:
There is no external sd card in the storage directory, but most applications scan this directory. You should be able to see the screenshot, the memory card is mounted in another location. Can I modify it myself? Or do you modify it at compile time? Thank you!
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] theimpulson:
I am not sure which app is that, but this is an app specific issue. I haven't modified mountpoints at all. Report it to that app developer.
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] theimpulson:
This is weekly, builds are automated. You can choose when to update though.
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] atmin:
This app is a file manager

I mean these music apps can't scan the music on the external memory card. The previous aex was normal.

Unmarked is the official system

For example, the scan directory of retro music is /root/storage/emulated/0. However, there should be an external storage directory under /root/storage/, but the external storage directory of this system is /mnt/media_rw.

I mean, the mount location of this external storage needs to be changed to the /storage/ directory for these applications to scan properly.
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] theimpulson:
I can't reproduce this in Retro Music Player as well. Please send logs as I asked earlier while generating the issue.
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] atmin:
The problem is that the player can't play and can't find the music in the external memory card. I have already sent it to you, thank you. You have two Sim cards installed, so there is no external storage. You can test it yourself by plugging in an external memory card. Thank you for your help.

[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] methuselah:
When you flash a custom kernel, you are own your own though.
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] AshleyNG2:
Did you restore your apps from an old rom/stock, such as by using Titanium Backup?

Try uninstalling the faulty apps and reinstalling direct from the play store.

Also take a log so we can see what's going on.

Which kernel did you flash?

I'm using this rom and am not having these issues.
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] zeft64:
I flushed fenix kernel and I tried everything above

Already
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] theimpulson:
No such issues here, this mostly happens when dirty flashed. Please do a clean flash again and check if issue persits. If yes, send name of apps, steps to reproduce the issue and logcat.

Yep, just checked.

Following step by step procedure = bootloop or reboot to fastboot mode.

Any suggestions ?
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] zeft64:
Did you format your internal storage so that it is no longer encrypted? Did you flash vendor first on both slots? Did you wipe dalvik cache?
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] ROKO__:
Yes, everything, i always do a format on any device which i flash with aosp.
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] zeft64:
Okay buddy do me a favor because something isn't right. Please post a DETAILED list of every step you took. I'll try my best to help you okay? I have work tomorrow so I'm probably going to be sleeping pretty soon but when I wake up in the morning I'm going to try and help you okay?
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] ROKO__:
Thank you

Well,step by step as it mentioned in OP.

I have success,but facing same issue as before. SIM not detected,I need to take it out and reinsert after every reboot.
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] zeft64:
Okay I'm sorry but that's not going to work buddy because the steps in the op aren't detailed. I need you to list what you flashed and the order you flashed and wiped things in. If you can't do that unfortunately I won't be able to help you.
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] ROKO__:
format all partitions.

as i always do on any device..

/data /cache /internal and etc.

flashed rom and then community vendor on slot a, switch to slot b and again, then factory reset again. Reboot
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] zeft64:
Okay so

1) you wanna make sure you wipe dalvik after flashing everythin

2) I need you to list every partition you wiped. I know its tedious but please do it. Again the more detailed you are the easier it will be to help you.
[Nokia 6.1 (2018) ROMs, Kernels, Recoveries, & Othe] ROKO__:
data cache system internal, flash steps mentioned below.

And as mentioned, after flashing, wiped /cache and /data
