[Huawei Ascend G7 Questions & Answers] Deleted member 12324997:
Hi, i have a bit of a problem with my own Huawei G7: it wants to stay dead.

Just to give a quick "backstory" of the device in question:

I've been owning it since 2015, so far so good, but after 3-4 ish years of usage it started to get issues without doing any particular stuff (ex. rooting, unlocking bootloader, etc.). I've used to update the phone whenever updates came out, and i was exactly on the latest M release.

Since i've got that update and, to add, a newer phone in late 2018, the phone decided to kill off itself.

Each time i've booted up the thing, it was making more and more struggle to boot up into android- even to a point of getting into a bootloop, or straight out softlocking after the bootup animation or EMUI trying to fix itself.

Latest times i've got it to boot the device up correctly, it worked fine, honestly-

no apps crashed, no strange behaviors from the os, but the only bad part were pics from my gallery got corrupt (not all, but a good chunk of it).

After next bootups i've tried, it decided to show no life except the notification LED.

The screen was dead, no vibrations started when booting up, but only the LED displayed a certain order of colors (blue, green, red, orange- then the pattern repeated).

After a long while, i've recently took it back to give it a fix.

At first i tried following typical solutions given on the internet, like:

button combos to boot the device into different modes, load an sdcard with an update.app package on the dload folder, even making it charge for an extended while (around 1-2hs) and see if it worked- but the phone was still dead, still shown the LED pattern.

Moving on, i decided to move to the manual work:

Disassembling, reassembling, plug off different modules (+ battery) and attach them back, also attempting to charge while i had detached the battery's pins with my nails. Still no signs of life happening. I've tried everything except one very thing: short the pins and boot it up to EDL mode (since it has QCom chip).

So, as a last resort, i've tried to search far and wide on the internet about a QCom FW for this specific device.

None to be found, except few useful sites:

The device's page over PostmarketOS' wiki (that's how i've found out about the points to short on the board);

Huaweistockrom's page on the device (i refuse to hyperlink it because their .xml file inside the .zip made QDL puke out errors about it having no correct syntax on the code. Didn't bother myself to fix it alone- also has 'wares inside, so i won't break a rule);

An obscure thread found over gsmturkey.net (the only one offering a perfectly functioning FW. If it doesn't load for you, here's an archive.org snapshot) + a functioning DL link;

Without further ado, i've went trial & error flashing the FW dump from gsmturkey's site over my phone's board via triggering EDL with pin shortage (with my rooted phone on the terminal to flash it).

Didn't felt like it took much, but i saw the terminal was reporting the partitions being written successfully, then QDL disconnected and printed somewhere in the text (possibly flagging it has flashed the FW successfully):

"partition 0 is now bootable."

By now, the phone should have shown signs of life- like the screen turning on or anything (like i previously did with another QCom phone).

Phone was still dead, but on the bright side: no more colored LED pattern!

I tried booting it up manually, even doing key combos, disassembling it and do other shenanigans to make it work:

the phone still was dead, but the only functioning thing was the red LED showing any signs of the battery charging- but at some point it turns off, no signs of the green LED nor the screen printing any cool battery level animation (like it should normally do on any phone when the OS isn't on).

Moving on, i gave a good ol surf around the web and found out something: this issue isn't uncommon at all, it exists even on older Huawei models.

For example, i saw across XDA itself and other android-centric blogs the specific issue of "LED turning on when charging, but phone doesn't turn on" kind of deal.

If i were to link up several for proof:

A P10 Plus facing a similar issue, over Huawei's consumer help page;

A very exact problem of what i've used to have too, over HTCMania (spanish page);

Same page, this time is about a G610;

Several users having the same malfunction, over the Ascend G6's XDA page;

A Huawei Mate 20 Pro, shared over r/Huawei's sub;

Another person- but this time's about the colored led thing, over Android Central;

Aside the list, i wonder if either the colored LED thing is a code for the motherboard or EMMC dying (even though convinced more of the mobo, if the EMMC wasn't alive: then none of the flashing could have took place) or a planned obsolescence made by Huawei for their own devices.

Whatever that is, i'll await for answers if my issue would be resolvable- or atleast bypass this red LED and black screen issue without putting extra expenses to buy new components (i was very affectionate of this device and would like to revive it in order to extend it's lifespan).
