Hi,
I am trying to see if I can spring an old Karbonn Titanium s2 back to life by installing a compatinble Cyanogen OS in it if I can find one.
I have ADB and FastBoot installed in my Windows 7 PC.
Now the problem I am facing is I just cant boot this damn thing into Fastboot mode.
So,When I do this
adb reboot bootloader
The phone simply reboots. Literally. Reboots.
On the other hand, commands like
adb reboot recovery
works just fine.
Its just the reboot bootloader command that isnt working, which is halting my endeavor at the very first step because I cant unlock a bootloader that is invisible and so I cant install a custom recovery in it.
Any Help??
Thanks in advance.
P.S: The device runs Android JB and is rooted.

Hello,
Recently I flashed a CWM file on my android 'Lava Iris X1 Grand'. Now my phone is stuck in a bootloop. For some reason i cant enter recovery mode even before my phone was stuck in a bootloop. I am not sure whether my phone has USB debugging enabled or not. I have even rooted my android with KingRoot. I have downloaded your Minimal Adb and Fastboot but it cant find my device.
Overall problem:
1) Phone Stuck in Bootloop
2)USB debugging enabled ? Not sure
3) Can't enter recovery mode
4) ADB wont find my device
Note : When I used Minimal Adb and Fastboot, when i type Fastboot devices some numbers appear but when I used the command 'adb devices' my device is not shown. I have a backup at my phone through the Flashify app but since recovery mode cant show I cant recover it.
Please help me out here. I don't know what else to do.
Thank You in advance

My phone is fixed now using SP Flash Tool
Hi all, I wonder if anybody can help with this.
my volume buttons are not working (hardware issue) and I was trying to install TWRP and a custom rom but, after installing TWRP the phone now always boots in recovery mode (at least this is what adb tells me) but TWRP does not really start, I keep seeing only "honor, powered by android" black screen.
adb is working but not fastboot. I tried to reboot to bootloader but it always go to recovery instead. I have no su, and I am stuck just with adb in recovery.
any idea?
If you have full adb access maybe you can restore your backup directly from it
Thanks Rayan
how? what do you mean by "full adb access"?
I tried to run adb sideload but it does not work (it says "closed" shortly after without doing anything)
I don't really understand what the issue is, do you have access to TWRP menu or not at all? And when you say that you can use adb, is the device recognized when you type adb devices ? And what happens when you try to boot in bootloader and use fastboot? Can you try to the command "adb reboot bootloader"?

Thanks Rayan, I finally solved replacing the volume buttons (found cheap ones). However adb was working but no matter which command I was sending (adb reboot bootloader) the phone was always rebooting in recovery mode but TWRP was not starting properly (could not see anything)
with volume buttons I managed to enter into bootloader, reflash TWRP and do everything I needed
Thanks
Hello!
I cant get further on with an my tablet an RK3168 device.All the specs are in this topic, because i was looking for a rom:
http://www.arctablet.com/blog/forum...ssible-clean-4-2-2-or-a-customcwm-rom/#p60994
But i ran into things what i can not really understand or place, and i also already tried a lot already..Maybe its the soc itself, hope someone can help me a little bit.
I wane install a rom, so i first made an backup with RK1.2tools and this backup is ready in flashtools1.37 from finless.It finds rk loader and its ready to flash..
But here i get stucked, adb works, minimal adb &fastboot , google usb driver, with usb debugging on..Adb works, but for example fastboot reboot-bootloader..Only switches off the device, it doesn't boot up in any mode...Tried button combinations but only recovery can show up.So no commands work for fastboot plus starting fastboot with keys, looks impossible.Also in recovery there is no fastboot.In adb i can see all the commands, but everything what starts with fastboot, will give me only an waiting for device output..Also adb shell gives me root, rooted with kingroot..But same thing, goes off and no fastboot..And yes adb has permissions from kingroot.
Because adb works, i can not believe that fastboot would not work, i think myself its the tablet who first has to boot into it before a driver will work.But fastboot oem unlock or fastboot flashing unlock bootloader all are not working.But why it even doesn't start in any fastboot from command pff i cant understand that..
On the internet i see that even fastboot has an screen..Could it be locked or so?
Only weird thing besides that is this! If i put it off, plug in usb cable and charger!!Press vol up or power, battery shows up loading..And i see rockusb device in device manager win7.I can install adb or fastboot on top off rockusb device.But adb shows no server running.And adb devices gives this: 1234567890ABCDEF Device....Thinks its no fastboot but very weird.It only works this way when charger is inserted and battery is loading..
Besides that, rooting was also a pain ...Tried rk188 solution for rk3168, but double zero after 3 times booting..Looks rooted, but Su is not there and cant get installed.It always ends like that, with or without kingroot.And other ways the same, with emulator pushing su and removing kingroot..Doesn't allow Su to be installed properly.
Nothing looks logical for me at the moment. No fastboot, but seems flash ready in RK1.37 tools.Is there a way around fastboot to find out first if my loader is unlocked.
I don't wane brick it with an locked loader, so how to get further on from here or are these soc different from others?
Thanks for any help!:good:

I tried using the Tool All In One to unlock the bootloader and manually through the adb and fastboot terminal. ADB recognizes the device even though every time i reboot to bootloader through adb or manually through the phone recovery and manual buttons it never sends me to the bootloader. i was able to flash the stock firmware with SP flash tool. I really just want to install TWRP. i have been able to root this device with Wondershare dr.fone root program. I wanted to get it to work with the All in One tool so i can install TWRP to install custom firmware. If anybody can point me in the right direction on why the bootloader never works and fastboot? Maybe this model the bootloader is unaccessible? And if i cannot get to fastboot to unlock the bootloader can i still install twrp somehow. Also when using fastboot command it shows the device id it just says waiting for device everytime and cannot get it to recognize past that point. Not being able to get past this phone problem has been really bothering me and irritating me lately so hopefully i can get it resolved. I will be back later to see if anybody knows a solution to this. it seems like i have been trying to do the same thing and maybe im right and fastboot mode and the bootloader is locked and currently not possible.
