[Galaxy Tab Q&A, Help & Troubleshooting] ndrsconschrtysvcs:
Flashed from 2.3.6 stock CDMA to ?

I have a lot of questions:

It is about a Verizon CDMA Galaxy Tab running 2.3.6 (P1000 CDMA, also called a P1C).

Installed CWM and did a NANDROID backup.

I flashed it to the latest Cyanogenmod nightly. The 3G radio continued to work for awhile, then died. I have no idea why.

I flashed it to the Cyanogenmod nightly just previous, no change.

I flashed it to another newer ROM (cm-10.1-20130913-UNOFFICIAL-p1c.zip) from AlRoger. Still no 3G modem service.

Found various references to the device needing a modem.bin. Could not find a copy online.

Keep in mind the CWM NANDROID backup from 2.3.6 exists. I was tempted to use it but CWM returned an MD5 error.

This device is on an active Verizon Family Plan account, with a modern 4G iPad. I have searched around and found references to extracting a modem.bin, several dead links to a modem.bin - nothing to go on.

https://docs.google.com/file/d/0By5pF101cmHZN21mUTNwUDhiRUU/edit I found this, an SCH-I800_Verizon_Stock.tar.gz, but not really sure how to flash it (heimdall).

are some links I used.

HELP!!

I would like to flash this latest, how do I get the CDMA modem working though?

It seems the process is to go back to stock, then flash immediately to this image.

update: I tried to use heimdall and it just says protocol initialization error. so i restarted the laptop and restarted the device, and now it just shows this: [see image] Phone - ! - Computer (turns out this is called Emergency Recovery Mode, and Kies can recover from THIS mode apparently)

update #2

Ok. What someone (sammy THANK YOU) told me on #android-root was the device didn't have a bootloader anymore. I got ODIN and a bootloader image and the device at least gets into Download mode.

update #3

Heimdall loads the SCH-I800_Verizon_Stock.tar.gz file, parses it like everything is fine. And then all heimdall ever does is get to

Beginning session...

(long wait)

Releasing device interface.

Update #4

From Download mode: Supposedly I can flash the same file as a Kernel. (?)

When using ODIN 3.04 or 3.09, and selecting PDA/AP button, and CF-Root-TAB7_XX_OXA_JQ1-v3.3-CWM3RFS.tar, and the Kernel flashes and everything seems okay. The little status bar fills up under the word Downloading.... on the tablet.

Attempting to reboot into Recovery mode though, all I get is all solid lights and a thin blue line through the display.

:(

Update #5

Extracted SCH-I800_Verizon_Stock.tar.gz to C:\android\Heimdall\fw.

Going back to the Heimdall frontend and getting nowhere. So I ran Heimdall from the command line:

C:\android\Heimdall>heimdall flash --CACHE fw\cache.rfs --PARAM fw\param.lfs --KERNEL fw\zImage --RECOVERY fw\recovery.bin --FACTORYFS fw\system.rfs --PIT fw\sch-i800.pit --repartition

And the device is booting with the original SAMSUNG then Verizon logo, and does not come all the way up, but factory reset (Power + Volume up then release Power at the SAMSUNG logo) does it.

I have reset data and cache now and am waiting...
