[Q] Bricked my S3, Telcel Mexico did apply my warranty... flashing Cyanogen now safe? - Galaxy S III Q&A, Help & Troubleshooting

(Just noticed this wasn't supposed to be the forum to post this... if a kind mod sees this thread, could you please move it to the Questions forum? Thanks in advance :3)
First thing you might want to hear: In Mexico, if you root or flash a custom ROM on your Galaxy S3, brick it, and your bootloader won't work, Telcel won't void your warranty. Why? Because the bootloader is the part that proves whether you have fumbled around your OS -- and therefore, if the bootloader doesn't work, there is no way to prove that your ROM is not stock, and in order to avoid possible lengthy legal action, they just fix it without saying a word.
For any paisano who might be googling in Spanish: En México, si rooteas o cargas una ROM custom en tu Galaxy S3, posteriormente se queda brickeado, y el bootloader no funciona, Telcel sí hace válida la garantía. ¿Por qué? Porque el triangulito rojo del bootloader es la parte que prueba que le has metido mano al OS -- por lo tanto, si el bootloader no funciona, no hay forma de probar que tu ROM no es oficial, y para evitar largas y tardadas demandas, lo arreglan sin decir nada.
Now that this is out of the way, here's my story...
>bought in February an international Samsung Galaxy S3 from Telcel, Mexico
>ran on rooted stock ROM for about 6 months, eMMC Check says I have the bad sudden death chipset
>one day, I declare that the stock ROM has run its course and flash CM 9.1 stable, during the whole time I forget that I have the bad chipset
>everything runs fine for 24 hours
>then I decide to install Whatsapp, Cyanogen freezes on initial set up (after receiving the confirmation SMS and setting my display name, before actually getting the chats screen)
>after the fourth reboot, Cyanogen won't start anymore
>I go to recovery and clear the cache
>recovery freezes too
>spend about 2 hours trying to make it work with Odin on download mode
>find out the PIT was missing, find one online and try to flash it
>it won't, the internet says this means my Galaxy S3 is now officially bricked
>submit it to Telcel to have it fixed
>one week later, it's fixed
>eMMC now says I have the good chipset
eMMC Check now says I have a Type 016G92 chip, date 01/1997, CID 1101003031364739323094152477107d, fwrev 0x30, and that it's not a Sudden Death chip. In theory I should be good now, but I so definitely don't want to risk another brick again. Does that really, really, really means it is now safe to flash CyanogenMod 9.1 again?
Also, why did CM 9.1 freeze while doing the initial Whatsapp setup? Is there a way to prevent or fix it?

We now have CM 10.2. Anything that has a version higher than 4.1.2 is safe from SDS. CM 9 is 4.0.x so it's technically unsafe.
Anyway, your chip is good, so you won't get hit by SDS.

Lucky you
Lucky you! I just went to telcel today, they had no issue with it being rooted. However when they sent it to Samsung, they sernt it back to Telcel and said warranty was void since it was rooted and they offer to replace the system board for 7880 pesos..
I explained the Telcel technician the situation, and he agreed, so they had me write up a long letter explaining the situation and have them reconsider repairing the manifacturing flaw under warranty as it is a recogniced hardware problem.
So in about 10 days, I will find out if Samsung is going comply. I fear they won't and will use the rooted phone excuse for not replacing they flawed hardware..
My guess is that I'll end up with a non functional S3..

It all depends upon what this claimed flawed hardware is .
But Samsung are vey specific on rejecting warranty .
Your claim should be against the vendor they sold the goods not Samsung and yes Samsung rejected the claim from the vendor . But the vendor still sold you the goods and if as you say its flawed hardware then check your countries law regarding the sale of goods .
