Now my 2nd zenfone 8 died, started with some strange google issues, could not add account.
Then b part of the a/b was corrupt and gave errors when trying to restore rom. Now it hard bricked as the1st ZF8.
I gave up on asus phones, going to s21 now.

Oh, don't go to s21... I came from s21! The camera is really bad. I can't understand how a flagship phone can be shipped with such a bad camera. Xiaomi 12 is a small flagship phone. I would give it a try.

I had the RAM dump some month ago but I was able to boot into fastboot.
Some weeks ago my phone turned off several times.
It went working well then for about a week till I made a restart.

After the restart I entered my PIN, the phone went dark and showed the ramp dump error and this time nothing worked anymore.

I sent it to ASUS and and it got replaced.
The ASUS report says:
"The error could not be reproduced. No hardware defect could be found"

This made me curious and I called the ASUS support asking for details. I also told them that this is a common issue which many people reported.
ASUS Support:
"The device was only tested for a short time and was then immediately flagged for replacement.
Officially we are not aware of such a common issue with the Zenfone 8."

However, I am glad that the replacement went fast and without hassle.

Funny enough, I was looking into alternative to Mi 12 (and Mi 12X), and was more interested in the Zenfone 8. But after reading this, I am more skeptical.

For me currently the Z8 has more ROM support (Mi 12 and 12X are non-existent), and better chip then 12X (possible supported longer), and better camera. But this issue of sudden death is absolutely a deterrent. I don't want to go with what OP went through. Maybe I should wait until the Mi 12X gets some dev ROMs and reconsider (I hate MIUI with all its botnets and bloats).

You'll be well off. The cases of ramdump vanished and I suppose if you have the refined model, it is not going to happen to you

My new phone is also now in RAM dump mode right after flashing the modified Magisk boot image :mad:
Did I just have bad luck or what could I have done wrong? After several tries to boot it shows "Your device is corrupt. It can't be trusted and will not boot."

Does anybody know whats going on here?

When I reflash the patched boot image, it still stucks in boot loop, but without the corrupt message.

If its due to a bad flash, don't worry, just hold the power button and the volume buttons so you can go into the bootloader and use the reset script to re-write every partition to a default state and start again. Maybe your magisk image is corrupt. I would check the cheksum to verify that its good. Also, maybe that image just does not behave well with the zenfone 8, it happens sometimes

I have encountered a ramdump screen several times because of bad manipulations and was always able to recover, don't worry, there's a 95% chance it's not a ramdump screen of death if its due to a bad flash :)

Yeah, I've installed stock fastboot rom, relocked my bootloader, sold my zf8 and bought th 12x...I'm happy TWRP and oxygen already there...

Which MFD are the bad&ugly guys?
I don't think it's known. We saw some stats here and on zentalk that there were 04.2021 and 05.2021 who got ramdump. There were 06 or 07 month too, but only a few devices.
And by the after some SW update ramdump cases decreased drastically.

great, i got a 04.2021 shipped in december 21 -.-
... maybe i should relock that bootloader soon and always keep a backup?

are there reports of the age of the devices getting ramdump? to go like "if your device survives 6 months, it should last forever"?

You should always keep a backup of any important data.
After around 4 to 6 month most ramdump cases were experienced from my knowledge. But the amount of people was limited. We had around 40 tracked cases at asus.zentalk. my device was also manufactured in April 21 and is still alive (working like a charm).

Where are you living?

in Germany, so i'm at least covered by extended customer rights ;) I always keep backups of the really important data but in this case i think i'll be keeping a backup of the "not-sooo-important" data also ;)

Ah se dschörmens, Grüße aus Frankfurt!
Well, then you are good to go in my opinion. Just keep backups and your receipt.

In the past, phones with heating issues and other stuff, which looked hardware related tended to receive the ramdump feature.

Grüße zurück aus dem Norden ;)

Okay, well, mine is not heating, sometimes gets a bit warm but not as warm as my old OPT under load, so i think i'm good to go, wanted to try some custom roms and like to be on the safe side ;)

    I have now my second ZF8, because i like it a lot. The first died suddenly in the first 6 months or so, luckely i got refund from the seller after a long email discussion. My secod Zenfone is still working. Its rooted like the first one.
    Today the phone of my girlfriend died, seams like "sudden death" too. She bought it used so no chance of refund, but despite so little chances of help I will try to somehow get in touch with Asus for an explanation and a solution.
    edit:

    Good News!!
    Short version: after one month emailing back and foth and arguing with Asus:
    I got refund a free new/repaired ZF8 in exchange to my defect and BOOTLOADER UNLOCKED phone.

    long version:
    first of all: I bought the phone for my GF. It was used with a unlocked bootloader and rooted, but younger than 2 years, so theoretical in warranty.
    First I fullfilled RMA formular and send device to Asus.
    In the beginning they declined the phone because "the device is not covered by warranty, because the given issue is a softwareproblem and thus not covered by warranty.
    Then the send my a cost estimate over 528,48€ for repair. Thats hillarious, almost the price of a new phone.
    I send an email and explained the issue while claiming it's a hardware issue. In this email I linked these forums:

    https://www.reddit.com/r/ASUS/comments/pshs89 https://www.reddit.com/r/zenfone8/comments/pd2ga2
    and told them to read carefully.
    Answer: No warranty, because of unlocked bootloader.
    Me: Unlocked bootloader has nothing to do with hardware issues. Have you read in forums?
    (Meanwhile ignoring emails refering to processing fees and the cost estimate.)
    Asus: Unlocked bootloader, means no warranty. Try to contact your seller and ask him for refund.
    Me: First I don't know how the reseller could help, becaus it's Asus fault. Second I don't care about warranty, fact: the device was faulty immediately after it left the production. I payed for the device, so Asus has to deliver. Maybe you didn't get the issue correctly so please explain it to me:
    Why has my phone died?
    Asus: We will check your issue and we get in touch again.
    Asus: Dear customer, we will offer you a free repair.

    Now the repaired or maybe new phone is on the way to me.

    Guys stay strong!! Take the time, It's worth it!!

    Well, in EU it's illegal to deny warranty claims due to customer changes that had nothing to do with the actual damage. I would just try to get a different person from Asus, it would seem pretty stupid that none of them are aware of this law.
    Well, actually I opened a case at the European Commission’s « Online Dispute Resolution » against Asus Europe, and didn’t get an answer, but 3 days later I got an email from UPS saying that they had shipped my repaired phone back.

    Still trying to get any apology/explanation from Asus but I guess they finally accepted haha, good news for me anyways.

    Hi,

    A week ago I was using my < 4 months old Zenfone 8 while traveling in Germany, and at 19% battery the screen turned black. I went back home, tried charging it for as long as possible, it was staying cold and never showed any sign of life.

    So I opened a RMA on Asus Belgium website (as I am from Belgium), and shipped the phone to their repair center.
    Today, I got an email from them, saying that the warranty wasn't covering the damage, and that I had to pay 500,28€ for a replacement of the motherboard.

    When going into their OOW website, I saw this table :
    Warranty start:2021-05-16Warranty end:2023-05-15
    Issue date:2021-09-13Receive date:2021-09-15
    Charge reason:OOWCustomer agree to quotation:
    Charge reason:OOW - Out of warranty ASUS Product Unlock Flag-oow scratched

    It seems to me that the "unlock flag" is their bootloader unlock tool, that I had indeed used to root the phone before, and wanted to try a few custom ROM - which I actually never did since there were none at the time. Of course, this is completely unrelated to the issue, as it is not even rooted anymore and I basically did nothing with it.

    As I am from the EU, I saw that there are laws that protect consumers from these types of abusive behaviors from companies, as explained here https://piana.eu/root/

    I am therefore
    1) looking for people who had this problem with their Zenfone 8 (what is it actually? never seen a brand new phone die like this)
    2) looking for people who had their warranty denied for an unlocked bootloader in the EU, and what is possible to do

    Thank you very much for your attention and for your help

    What type of zenfone did you have?

    I am wondering whether only 256GB phones have this issue
    256GB that died, new 128GB is ok
