[DEV ONLY] Dual Recovery for Xperia Z1 (LOCKED BOOTLOADERS)

DooMLoRD · Sep 23, 2013

info:

this is based on the XZU recovery for locked bootloaders by @Krabappel2548

This thread will stay a dev and discussion thread for further development issues and fixes!

Download link can be found here: XZU recovery for locked bootloaders

THIS IS INTENDED FOR LOCKED BOOTLOADER DEVICES! But works on Unlocked bootloader too

THIS IS STILL IN DEVELOPMENT STAGE!

DO NOT EXPECT IT TO WORK PROBLEM FREE!

requirements:

rooted Xperia Z1

how to enter recovery:

when you see the Sony bootlogo and when device vibrates/leds light up u can use the entry keys to enter the corresponding recovery

VOLUME UP -> CWM
VOLUME DOWN -> TWRP

what works:

BOTH CWM 6.0.3.6 and TWRP 2.6.3.0 work
you can enter both recoveries and flash small files

what doesnt work:

in this particular version of CWM, adb doesnt work; it will be fixed later.. for debugging use TWRP

Shoudl be fixed:
TWRP and CWM both can destroy /cache and /system when trying to format it. Restoring your phone using an FTF is the only option left if that happens. You can however try to not format but use rm -rf instead in TWRP (TIC BOX!!), which will do for now.

For anyone who does not own a Z1 (like me) and wants to search through the init actions.

Look also L2 Error detected! in 1089 Line. Usb don't work right and i think because we can't write in memory stack stack(0xe4859e70 to 0xe4859eb8) for lock bootloader. Problem it's in arch / arm / mach-msm but i don't find where!

As DooMLoRD's OP somehow does not fire the mention system... repeat for function

@Kali- @Bin4ry we need your help guys!

Oh now I got marked. I'll take a look at the weekend I don't have time Today sorry!

But just for me to know, ist that selfcompiled or a copy n paste version with a unpacked -> repacked ramdisk?
Have you checked against my posted recovery in Z Ultra forums? I can remember there was a similar problem on the locked bl recovery, you guys really seem to screw it somehow.
Also can i get a gdrive link to the files? Then I can grab it over my different systems more easy

It was a self-compiled version by @DooMLoRD, with a ramdisk slightly modified to get it to work for the Z1. What did you do to get it to work on the ZU? @krabappel2548 tried and failed there too...

EDIT: Just to be clear: it's not that the recovery does not work, it does, it's the kernel which triggers a reboot after 40 seconds because it seems to be unable to initialize the modem.

the boot hijack scripts, chargemon, are based on the ones for Xperia Z by @[NUT], with the necessary modifications, if any, for Xperia Z1

the ramdisks for the recoveries are using the same CPIO as the ones for unlocked bootloader...

recovery works well on unlocked bootloader with recovery integrated in kernel ramdisk...

will send u link over gtalk

did u post recovery for LOCKED bootloaders for Z Ultra?

Bin4ry · Sep 28, 2013

Ok i did some first tests!
My own recovery works (see cm boot.img !). But this one does not work when ramdisk-recovery is integrated into your dualboot script!

So it is definetly a problem with the services from the "host" system. The ramdisks which get extracted also work fine when integrated into cm boot.img!

So wild guess here: You try to stop all services from host system but it seems not to work, since you dont really need anything running for recovery, but some of the host services dont want to stop here and waiting for the system to bootup. SOMETHING seems to reboot it then when nothing is happening

Need to see deeper whats happening, its quite a funny problem i think

Regards

I came to the same conclusion, but I had to give up as I had no idea what services could have been responsible

It might be the RIL service as it slingshots a lot of the radio/modem functionality... But I'm really not too sure...

original ramdisk and the files from /system/etc are now in post 3 for anyone without a Z1 to check them.

Did you find anything useful yet?

I've been wandering around in the files again myself, i've checked the qcom modem init already but i rechecked it, it seems that before chargemon is started, it already initialized a lot of the radio/modem hardware... it seems that at least one service is responsible for the communications layer between the kernel and modem, but I have been unable to determine which one... seeing the 40 second timeout before a reboot occurs it probably accounts for the service needing some time to start up.

jos_031 · Oct 1, 2013

Since kernel have initiated the modem, is it possible to write a procedure to set smem_get_entry flag. most likely to assign flag one to it.. New to android development..When i program a micro controller..we will be checking a flag in modem to see if it is initiated.. or sometimes.. i assigns a variable or memory address...so instruction will check that location for status rather than checking modem flag...as it takes more cycles...so i think this may be clearing some flags or memory or variable....

I did not had time yet to continue working but boyhood you guys should be correct. I am just thinking of the easiest way to fix it. Give me some more days please

I've had a chat about it with Dees Troy from TWRP about it, he suggested RIL as a possible culprit, or maybe watchdogd...

I don't have a z1 so I'm unable to test it on my own...

For watchdog to reset an unexpected condition should occur.. for that something else have to go wrong...

and not sure- Radio Interface Layer is it not part of baseband?

Yes, it is: so it's tied in with the modem hardware...
