Jtagging an android phone

[ZgamerR]

Hello

I have a question to do with the jtag, actually a couple of questions.


So here is what happened:


I have (or had) an samsung galaxy s2 and I think I have hard bricked it, don't know how tough. I was prompted to download the updates for the apps i have on the play store, afterwards i came across an error saying something like 'failed to install'. And after that everything started crashing, so i thought a restart would do the trick and fix it. So i left it for about 5 minutes and the it still hasn't shut down, so the best thing i could think of was to take out the battery, afterwards i couldn't turn it on(No vibration, screen was black) I have tried the usb jig and failed (either because i was using Stock ICS or probably because the bootloader has been messed up somehow), So the last thing i could try is to send it off to a company near my area who jtag phones(already found one).

The cost is not that big so it doesn't really matter to me (only £25) and im about 99.9% sure that i will do this, but i just want to know a couple things to be sure before i send it off to be jtagged.

1. Does my whole phone memory get deleted in the process?

2. Will a jtag solve my problem?

3. After the riff box or something other has finished jtagging my phone, will i be able to use the phone normally and be able to flash roms?

4. Does jtagging affect anything else other than the software (bootloader,modem etc....) ?

5. Will jtagging my phone bring any thing extra (except the fact that it will work :3 )?

And also i am not really worried if it don't ever work any more because i do have any other sgs2 that i can use but having 2 would be better for my personal use ( long story about why). Any answers will be appreciated Thanks

I don't seem to have any warranty on my sgs2 so i cant send it off :L and also jtagging isn't just like rooting it, my friend had to jtag his phone because he was being careless and loaded up the bootloader from a different phone on his galaxy s, so i think i have a problem with the bootloader because if i put the battery in my phone and leave it there it kind of gets hot ( same when charging ). I'm nearly 100% i need to jtag it as jtagging restores everything to factory settings by replacing the system partition with one thats working

Did you tried connecting your phone to PC and restore it via Kies? And if it doesn't works, you can try flashing a stock ROM and Kernel with Odin(Kies still needs to be installed.) Also check if your phone can enter Recovery Mode(By pressing Volume Down, Home and Power button simultaneously for 10 seconds.)

Also, one does not simply install a bootloader! That too of another phone!

oops sorry forgot to mention that there is no way of turning it on ( messed up bootloader maybe? ) so this means i cannot do cwm recovery/kies/download mode. Because of this i think jtag is the only way
