[Bootloader] [Android 4.2] JOP40C Bootloader version 4.13 flashable in recovery

Update: This bootloader is older and is not the newest available one. If you want the 4.18 version one go to THIS post and flash it with fastboot.
Older bootloader version: Doesn't flash and take hold for everyone, flash at your own risk
Usefull for people that don't want to flash in fastboot. The official OTA for 4.2 flashes this bootloader through recovery in the exact same manner

You need to be aware that on my Nexus7 the problem with Custom Recovery on the newest bootloader still exist.
Means you need to downgrade to 3.34 in order to flash CWM.

I need to be aware of problems that happens on your Nexus7? I don't have that issue I flashed TWRP Recovery just fine on this booloader...

No, I did not write to you personally. Glad it worked on your side.
Just the people to know.

That's really strange. I would try flashing the 4.1.2 factory images even though it might wipe everything including your sdcard.

Did that, thanks. Indeed wiped everything
Glad I had a backup

Hey guys,
So, I can flash this file from TWRP and it will upgrade my bootloader?
Thanks in advance!

you can, but make sure you check MD5, flashing a corrupt download can kill your device. OP, you should add a MD5 check in the zip if possible. but thanks for this none the less.

If you have a rom like cm10 installed or other rom that has buysbox in it, just type busybox md5sum /sdcard/bootloader-grouper-4.13.zip
Either in terminal emulator or adb shell.
If your on stock you'll probably want to check it with a program on your pc or install busybox from one of the playstore busybox apps. Of course you'll need to be rooted.

I went ahead and added sha1sum, sha256sum and sha512sum checks.

I have just flashed the file and thank you, I no longer have to keep my power button pressed for 20 seconds just to have my tablet go on
Thank you so much!!!

If anyone has any problems there is a link in my SIG to fix it or if you just need to revert back...

Just a FYI the older bootloaders are in the factory images! You can extract them out and flash the bootloader separately if you don't want to flash ALL the factory images. So far flashing this with twrp I have not had one single issue yet to speak of... Each bootloader is meant to run on specific platforms, recoveries, kernels ect. So on that note I still suggest if you want to revert your bootloader you revert completely with the factory images.

Hi,
thanks for that but when i falsh it in TWRP it's wipe all my data but i still have the 3.41 bootloader?
I'm not sure if i understood the thing to do with the md5sum?

f*** this bootloader i flash it yesteday.........
and my tablet stay on bootloader and i can't flash google image 4.1.1-4.1.2-4.2
why??
i can't downgrade bootloader too.........

CWM + CM10 stable
I just flashed this bootloader using CWM 6.0.1.0 and CM10 stable. I used Chrome to download it and the md5sum command in terminal emulator to check the md5 hash before hand. It flashed fine, I have the new version number, everything continues to work. Very easy.

Wondering does the new boot loader support older custom ROMs and the nexus toolkit, will I need to re unlock bootloader after flashing it ?
Answered my own questions flashed with cwm still have root but don't know how to check if boot loader is locked or what version I have. Works fine with cm10.

When you power your device on you hold the volume down button to get into bootloader. On the main screen it will say what version it is.

Aroma installer issue after s-off

After I obtained s-off I have been having a strange issue where anything using aroma that I flash comes up with a turquoise overlay the entire time and I get install failed each flash, but it seems to fail after everything finalizes and the roms or kernels appear to flash successfully, I haven't had any issues so far.
I guess the question would be, is there a way to clear anything related to aroma? I don't know if it stores something on the sd somewhere, but it remembers my options each time I flash something so it must be stored somewhere

probably not, with all the recovery changes and stock jb ota. i would say only use twrp 2.3.3.1 or official cwm. also if you have jb make sure to downgrade your touch panel firmware. anytime you change recovery make sure to "fastboot erase cache" then rewipe cache in recovery that can fix alot of recovery issues. also make sure to wipe everything when changing roms. what rom are you try to flash and what recovery are you using?

I flashed twrp 2.3.3.0 and all is good again. Thanks!

[Q] Can't Enter Custom Recovery?

Background: I am still on ICS 4.0.4 rooted and unlocked (atleast ez unlock says im unlocked and i have superuser and voodoo says im still rooted) .
However, when I try to flash a custom recovery , ROM manager gets stuck at 100 % and closes. I have also tried installing a custom recovery via EZ recovery, and it says its flashed. However, when I boot into recovery mode, all i see is the stock recovery. So I am not sure what is going on. Do you guys have any idea?

If your still on ICS try selecting an older recovery? Some newer versions are not meant for ICS anymore I believe ...

I recall a similar issue I had due to the bootchain...not sure if that would apply here or not though

I was reading somewhere that samsung devices auto -overwrite a flashed recovery and change it back to stock. I am not sure how to combat this issue , or whether this affects anyone else?

You could try flashing a recovery through odin, that might give a different result. I think when you boot straight into recovery mode from download mode after flashing it might ask you to disable the phone from auto restoring the stock recovery.
I could be wrong though, it seems that's a common thing that happens when rooting a 4.1.1 or 4.1.2 base. However, flashing only the recovery file should still work for an ics base too. Just make sure it's a tar file, not an img file for the custom recovery for use in odin.

Help, every ROM I've tried just gets stuck in bootloop

Ok, Ive unlocked my bootloader, installed CWM, rooted my device and checked that it worked, and when I go to the boot loader and select recovery it takes me to CWM. Ive made backups from it and and they restore fine. I even installed a custom kernel and it worked because noFrills let me OC/choose a different governor. Yet from the three ROMs Ive tried so far, they install fine, no errors from CWM, but when I boot up it just gets stuck booting forever. Ive tried wiping everything, Ive tried wiping some things, heck I even tried wiping nothing but I still get the same issue. Id really like to try a new ROM now that I went through the trouble of voiding my warranty, so please try to help me. Thanks in advance, alexbenh

Same here

Gonna try out this guy's method real quick except with CWM

I know this seems obvious, but are the ROMs you are flashing specific for your device?

yes, I have the Moto G XT1034 and have flashed ROMs before on my old galaxy exhibit and never had any trouble with that

Join the club, same here, done everything right but no custom rom joy for me

If you're flashing a kitkat ROM, make sure you're already running KitKat. If you're still on 4.3, then fastboot flash the stock 4.4.2 image first, then try custom roms
Sent from my XT1034 using Tapatalk

WOOOHOOO, I reinstalled the stock 4.4 firmware and everything, I couldnt root it with superboot so I just skipped the rooting step. Then I flashed CWM through the bootloader although I decided to take a risk and instead of "fastboot flash recovery recovery.img", I did "mfastboot flash recovery recovery.img" just to see if it would change anything. Not sure if thats why it works for me now, but its worth a try. Good luck to the rest of you who have this problem.

Yes, I was already running the stock 4.4 ROM the only differences was that I had a custom kernel which could possibly be an issue, but I wouldnt think so

huh, I had not tried using TWRP, but I thought CWM had a fix permissions command as well.

My experience. I tried CWM then loaded a Rom, the first one I tried being CM11 = Bootloop, Then I tried several other Rom's and always the same result, spinning on Bootloop
I then put the phone back to stock firmware 4.4.2 and tried TWRP version TWRP2630, no joy even the bootloader wouldn't work right.
Finally put the phone back to stock AGAIN (now getting frustrated!) and tried installing TWRP2631 using fastboot. That did the trick, now all ROM's load and run fine. This version of TWRP appears to be working well. Backup/restore works, and no problems at all.
Other's report CWM works well, but not for me unfortunately.

Z5 not booting

Hi All
My E6653 is no longer booting after freezing while running a custom rom. When I boot, it shows the Sony logo, then the light flashes red. It does not let me enter TWRP.
I have tried flashing original firmware using flashtool, repairing using xperia companion and the same issue happens.
I have tried flashing different custom kernels and TWRP versions. The only version of TWRP that works is TWRP 2.8.7.0 by AndroPlus but I cannot access the device through usb and adb does not work.
If anyone has any ideas on how to fix I would be super grateful.

What have u done to make ur device freeze, and which kernel were u using before freezing?

Thanks for getting back to me. The phone froze while using the Plex app, and after I force rebooted, the boot issue happened.
I was running V2.3.3 of Xperia X ROM by _LLJY and the kernel that came with that custom rom.

Well the Rom's kernel which u were using does not include TWRP, just try one of these solutions :
1/ flash ur original kernel, or reflash ur official firmware using flash tool and DON'T EXCLUDE any thing and wipe user data / apps log... ETC simply do a clean install with out any exclusion
2/ If u have ur original kernel patched with TWRP img inside, directly flash it using flashtool and enter TWRP.

- I tried this with 2 different official firmwares and no luck. I made sure I didn't exclude anything. It still gets stuck on the Sony logo
2/ If u have ur original kernel patched with TWRP img inside, directly flash it using flashtool and enter TWRP.
- not 100% sure what to do with this. I don't have the original kernel patched with TWRP img inside. Is this something you have?

Try this: Install Androplus kernel and Twrp Recovery which comes with him.
Find flashable prerooted firmware for your model than connect phone to pc to transfer it when you are in Twrp and than wipe cache,dalvik and data and try to flash prerooted zip.

Tried this also. kernel and recovery seem to install fine. But when I press VOL up or down, it does not go into twrp.

I managed to get into TWRP using the version from here: http://forum.xda-developers.com/xperia-z5/development/twrp-3-0-2-cm-aosp-roms-t3373008 with AndroPlus kernel. But, cannot access the phones storage through computer. TWRP shows failed to mount /usb-otg (invalid argument).
