Hey there fellas,
Being a part time/spare time "mod wanna be", I've successfully modded different cell phones every now and then.
Lately I bought, 2nd hand, a XT925 running as it was in the attached screen shot + unlocked BL, rooted and CWMR touch 6.0.4.4.
Since the phone was rebooting itself kinda often, since I've been told that Epinters builds was JBBL based and also based on the phone info 3.0.x Kernel, I thought it was ok to flash a stock ROM and after that, upgrade to KK via OTA.
I've flashed the JB 4.1.2 BR Retail via fastboot and everything went ok. I let it boot, ran through configurations and just made myself sure that basic options were working ok. The OTA pops up, I downloaded it and proceed to install...an error pops up while it was somewhere around 25-30% of the flashing process.
I talked to the previous owner and he said that he went to CM because the cell never was able to install OTAs, there was always errors on the installation process.
With that in mind, I proceed to research some tutorials about alternative methods on how to install KK OTA.
I've found one here and another one on other forum, which was more suited to my needs since I'm at Brazil. Both are suggesting the same method:
Requirements:
1.Stock/unmodified JB4.1.2
2.Stock recovery
3.Unrooted
4.Bootloader unlocked
Since I met all the requirements, I proceeded to give it a try.
The next steps was:
1.Download a JB custom recovery and flash it via fastboot
2.Correct OTA installed on the external SD card
3.Install the OTA via custom recovery
4.install KK custom recovery
5.Root
Steps 1 and 2 were ok but again, while attempting to flash the OTA there was errors. Since Ive tried the whole process several times with different files, doing MD5 checksums, with different custom recoveries, I may divide the errors in 2 separate categories:
Error category 1:
While verifying current system, different .apks has unexpected contents. Status 7 as the final status error.
Since I was battling with this for 36 hours non stop, just before going to have some sleep, I decided to format internal SD since I thought maybe there was some leftovers from previous installations.
Apparently everything went ok and i proceed to flash the another SBF this time (I was trying the JB4.1.2 BR Retail). Since I've heard one of the latest KK kernel was the DE I decided to give it a try. Downloaded it from the official motorola page and flahed it via fastboot. This time I didn't stayed on front of PC because I needed some coffee! When I cam back, everything seemed to be ok since there was a message at the end saying so.
Phone rebooted and JB4.1.2 was installed, basic configurations done and OTA downloaded through the cell phone. Installation failed again! With this OTA fail already in mind, I previously downloaded the DE OTA from a post here and had it downloaded already to the external SD card. Installed JB custom recovery and proceed to flash the OTA...it failed again!
There was almost 40 hours without sleeping so my brain didn't allowed me to keep going.
After 10 hours of rest, I was back to keep fighting....and there comes the next type of errors:
Error category 1 +2 +3+4
1+2+3 because after several attempts on the whole process, the error 1 popped up some times, there was, as well, a new error (error 2) while flashing the OTA via custom recovery (please see the attached screen shot).
Finally, the errors 3+4 (actually the error number 3 is the one I'm concerned the most about). Its sort of a bootloader menu error message and the error number 4 shows up while trying to flash SBF and or Custom recoveries and they are as follow
Bootloader menu error message:
10.98(*) (sha-5b608bc, 2012-11-23 19:48:44)
eMMC Info: Size16GB
Device is UNLOCKED. status code: 3
Fastboot reason: Boot menu selected
USB Connected
downgraded security version
Update gpt_main version failed
Pre flash validation failed for gpt
Fastboot error messages while trying to flash SBFs and or custom recoveries
<bootloader> Variable not supported!
target max-download-size: 30MB
FAILURED (remote failure)
My conclusions/doubts are as follows:
1.Does that internal SD format has something to do with the bootloader menu errors message? I feel it has started to show up after I did it...maybe it's just coincidence though!
2.The .xml editing part still making me feel something suspicious about the Fastboot error messages.
3.Does that Epinters CM11 KK 4.4.4 Kernel 3.0.101-11512-g9511901 has something to do with that scaring Bootloader error message about downgrading?
...or is it just me being a noob?!?
However, If you came this far, congrats! I really truly respect your commitment to help people and your passion for computer/programming/Android related things!
People like this are the real responsible for bringing men out of caves all the way through the days we live in and as far as to reach the moon!
Now if you help me to get out of this and reach my goal of having KK4.4.4 official DE(or any newest other one which works where I live), rooted, unlocked BL, I'll be more than happy to ask for your permission to invite you to some beers!
Cheers!
