Hi paziusss,
I am on the case of recovery bootloop after flashing CWM.

Thanks for this work but how does it work ? How to use the files on the link ?

Many thanks for your answer.

EDIT : Well, I will answer myself telling my solution
1. flash cmw with odin
2. reboot into recovery and flash twrp.zip
3. reboot recovery
4. Flash root zip
5. reboot system ..... no more bootloop

Flashed this with Flashify and it has fixed my bootloop issue.

Working well, tested on 2 tablets, thanks.

 

[paziusss]

I'm glad it worked for you

I just noticed some non-critical errors:

- it doesn't backup boot.img
- wipe preload partition does not work because of Selinux
- screen timeout (sometimes) puts the system in unresponsive state -> Disable it!
- Missconfigured "screen_brightness"

Everything else should work as expected.

In the next days I'll upload a new version to fix above errors and make an odin installable tar.md5
Next version will be shipped without SELinux, because we don't need that until samsung releases 4.4 for the Tab3 lite (or someone ported CM11 with Selinux support)

Feedback, as always, is _VERY_ welcome !!!

boot loop gone on T110 ?

In the next days I'll upload a new version to fix above errors and make an odin installable tar.md5
Next version will be shipped without SE Linux, because we don't need that

Wow! Does your kernel mean T110 users have a custom recov which does not bootloop anymore?

That would be awesome! Fantastic break thru on T110 ! :good:

 

[mai77]

no stock ASR install

this recov does not simply install via stock ASR on my T110 (reboot, "missing signature").

I guess one has to flash PhilZ first using ODIN, and only then install this recov from within PhilZ

 

[paziusss]

Uploaded a new version! for both Odin and recovery!

Tested last two weeks and everything works well!!
Have fun

 

[mai77]

brief install how-to much appreciated

new version! for both Odin and recovery!
Have fun

people would have more fun if you dropped 1 or 2 lines about how to install the NON-ODIN version.

does one have to flash CWM with ODIN prior to using that ?

So that stock users should go for the ODIN version straight away cuz it saves install time?

Also:

is this TWRP permanent and does not exhibit the dreaded bootloop? re-edit : YES this TWRP exhibits NO bootl loop acc. to DEV.

i.e. T110-users finally do indeed have a WORKING CUSTOM RECOV ? re-edit: YES ! FINALLY THE BREAK THROUGH IS THERE !!

that would make you the KING DEV of planet-T110 ! :good:

 

[mai77]

excellent !

:laugh::laugh::laugh:

smashing ! for us T-110 users the day has finally come !


KING of "planet T-110", the dev Sir paziusss

gave us a non-bootlooping custom recovery !

we now can handily

• root (straight from within TWRP, works like a charm)
• flash customs roms (well there are only 2 for T110: Criskelo and stock debloated)
• above all: make nandroid backups & restore them

just flash the recov with ODIN 3.09, see pic attached :

in TWRP, if u do a "advanced wipe" and wipe "internal storage" too (all is tagged except "MicroSD"), then that will kill the bloody bloatware installer that will otherwise spam ure storage with sh!tty apk's after fresh stock ROM or Criskelo ROM install (as part of most branded versions) .

I guess u get the bloated stuff back when flashing full OS with ODIN.



I found however, that Criskelo deletes TWRP. You would have to reinstall TWRP. Instead I chose to kill Criskelo which was OK but slightly bloated, I felt.

I run this TWRP , no prob so far. excellent T110 feel.

Am I the only one confused as to why this is such a big deal? I've been using the 2.7.0.1 version of TWRP for the T110 from here for over a year and have yet to experience a bootloop or problem of any kind.

well did anyone report successful use of that recov earlier ?

clearly PhilZ recov is bootlooping and no one suggested a replacement. :crying:

You're right here. Bootloop problem only happens if you tell your device to go to recovery (via adb reboot recovery, or with programs like quickboot). If you boot in recovery with buttons combo you'll never see a bootloop cause the tablet doesn't know it boots recovery. The only real scenario you'll find a bootloop is after a factory reset, because It will trigger a reboot-recovery like command and custom recoveries don't handle this. I didn't try to change this from userspace (I know some phones have a /misc partition with BCD data inside, but Tab3 don't). Instead I built a kernel from stock sources which triggers "recovery-done" at every reboot.
