[FIX] [GUIDE] My story of how I messed up in Aroma Installer + Fix

I was trying to flash the Lifeless rom back onto my phone, and had Aroma wizard started up, and was checking the options I wanted, when I remembered that absentminded me had forgotten to do something in the OS that I can't remember at the moment. I didn't see a cancel button in Aroma, and since I'm so impulsive, I held down power and volume up to reboot the phone. It nearly booted to the OS, with the capacitive keys lighting up at the bottom, when it suddenly shut off and attempted to reboot (maybe because I was flashing AC!D audio earlier and had checked the build.prop tweaks). It didn't reboot, but seemed BRICKED.
Ok, the actual problem.
It seemed totally hard bricked to me, nothing when I plugged it in to my PC or charger, so I, enraged, walked away and left my Optimus plugged in. When I came back, I saw that the notification light was blinking red, one shade of red brighter than the other. I gained some hope back by...
The FIX
... following the directions on YouTube (look it up, I can't post links) on performing a hard reset by disassembling the phone and disconnecting/reconnecting the battery connector. I, however, had to do a little twist to get my phone to PARTIALLY boot.
When I detached the battery connector from the mainboard,(phone still plugged in) the phone would proceed to bootloop, showing up the unlocked Google screen, etc. (flashed the ZVB Teenybin, that's why the Google screen) until it got to the battery charging icon in the center with the lightning bolt in the center. At this point, I reattached the battery connector and BOOM, the phone rebooted NOT LOOPING , PARTIALLY STILL but with the battery icon animation stacking up.
Unfortunatly, my battery was nearly dead so I then waited for a bit and let it charge up.
I held down the power button + vol up (on my bare phone with the backing taken off) to get it to boot into fastboot, then TWRP to flash the rom. I SUCCESSFULLY flashed the rom (relieved at this point) and I booted FULLY :laugh: . It got me to the Optimizing apps numberhere/biggernumberhere screen. Suddenly, the frickin phone shuts off and the notification light blinks red, but with a delay this time instead of a brighter shade of red. I did what I did before numerous times, but the phone would stay alive less and less.
I let the phone cool off for a bit (Heating issues on the Optimus ), tried charging it again, and I managed to finish optimizing my apps. It loaded up the lock screen for a split second, and then shut off with the LG goodbye animation.... Which is a hell of a lot better than a blinking reset light.
So after it shut off I let it charge...
And I was back!
NOTES:
The video I describe was originally made to resolve some other reset indicator, with alternating blinking capacitive buttons and the notification light, but also helps with the issue I had with solely the notification light blinking.
I don't think that anyone has had this issue since not really anyone is retarded enough to force reboot with Aroma loaded up.. but I decided to type this up just in case.

[Q] Hard soft brick???

Until two hours ago my I747 was running fine. I picked it up and attempted to unlock it and got nothing. I decided to try to pull the battery and do a reboot, it got to the KT747 splash screen from the kernel I run and went black. I tried booting into recover and download mode. Recovery mode gives me the little blue text at the top left of the screen indicating its booting to recover, black screen and nothing. Download mode pops the warning screen and 2 seconds later, whether I press up to continue or not, it goes black screen as well. I was running a rooted version of TW 4.4.2 with the TW version of Ktoonsez most recent kernel. I have been running this combination for over a week with no issues. I tried creating a 16gb debrick sd card but the phone doesn't want to stay on long enough to boot to anything. Any suggestions would be greatly appreciated. If there is any other information I can provide, please let me know and I will add it.
****edit for more info*****
I tried having odin open on the pc while i booted into download mode. Removed battery and usb cable from the phone, inserted battery while holding vol down and home. Download mode came up, pressed up to enter and quickly inserted the USB cable. Odin detected the phone and one second later shows it was removed. I have tried multiple USB cables as well.
****edit for still more info****
After several hours of cussing and google searching I came across a thread that described my issue perfectly. The solution turned out to be a stuck power button on the phone. Just like my phone, the one in the thread would boot immediately when the battery was inserted and shut off at the splash screen. Recovery and download mode both did the same, as does my phone. The site suggested rapidly tapping the power button to jar it loose. This did not work for me. Neither did the suggestion of sliding a finger nail into the gap between the chassis and power button. I went so far as to disassemble the phone and remove the physical button from the case. I put the battery back in and the phone booted immediately. The problem persists, the phone shuts off completely after a 2 - 3 seconds. This occurs with the battery in or with the battery out on USB power.

Sometimes messing around with the power button will work, but not always. Its only a temporary solution in most cases anyway.
The switch appears to have gone bad and will need to be replaced. I believe the part is only a few bucks if you want to DIY. Otherwise most local cell phone shops can do the repair relatively cheap from what ive been told.

Z1c dead after disassembly

Hey guys!
A few weeks ago my phone(z1c) fell on the ground (directly onto a metal bar) and as a result the touchscreen cracked and died. Since I didn't want to spend much money for a new display+digitizer I bought the Z3 Compact. But a few days ago I found and bought a cheap one from ebay to revive my touchscreen-cracked Z1 compact as a secondary phone. Boring story - I know.
Well, yesterday I disassembled it (dumb me startet to dismantle it from the backside till I recognized that I can't swap the screen from there. (I completely dismantled the backside at that point)). Since I didn't have enough time to fiddle around with it any more I left it dismanteled till today. So today I reassembled it and swapped the display and there I am:
My phone is dead. It wont turn on. It just shows a red led when I connect it to the charger. I can't get it into Flashmode nor fastboot mode. I tried the Power + Volume Up reset as well as the 'Off' button beside the SIM-slot. Doesn't change anything. If I connect my Z1c to the charger with the battery _disconnected_ it slooooooowly blinks red. (Like 10sec red 1sec off).
Any ideas on how to proceed?

Ok now I tried with Testpoint but I can't seem to get it into emergency flash mode...
This is what I'm doing: Connect TP to GND > Plug In MicroUSB > Red LED is on > Disconnect TP > Red LED turns off after a few seconds
This is what happens without TP connected: Plug In MicroUSB > Red LED is on > Red LED turns off after a few seconds > Red LED turns back on > ...... (flashing slowly)
Am I doing something wrong? I attached a pic of the mobo
@munjeni D:

Here i've another pic of testpoint

That seems to be the same pin as I am trying to use. Still no luck to get it into emergency flash mode :/

Xperia ZL weird problem

Hi All,
I recently tried to fix my older sons xperia zl, The phone would not power on, it did not show any signs of life when plugged in to a computer. Tried all the different button combos and the off button at the back of unit but still nothing.
So I opened it up and checked each component visually, did not notice anything wrong.
I decides to see what would happen if I disconnected the battery and plugged it in to just usb to the computer.
Well it showed up in device manager as a SEMC flash device, and the red notification light came on. Then it started to try to turn on without me pushing the power button, the screen gets to the sony logo and then goes black and starts again.
The next thing I tried was to flash a new rom to it, under Flashtools it automatically goes in to flash mode, found my rom and hit flash and it completed the flash. Disconnected the usb , connected the battery but nothing no power and still nothing in device manager.
Another weird thing that happens is that while the battery is disconnected and i hold the vol+ a blue notification light turns on and the phones goes into fastboot mode.
I initially thought the battery was the problem so I ordered a new one and installed it but the same thing keeps happen, anytime the battery is connected the phones does not react to and buttons, even when the usb charging cable is also connected.
I am wondering if someone has a schematic or know of a capacitor, resistor or fuse that is stopping the phone from recognizing the battery.
Any help would be greatly appreciated.

Stuck in low battery boot loop

Hello, Huawei gadget friends.
My watch started to go in to a "low power boot loop" a week ago so I left it alone hoping a full drain would restore it back to working condition, but alas not.
So now this is the situation:
1) press button, nothing happens
2) connect to power shows the charging icon (white battery with power sign) and then after a few mins commences a boot loop as follows
3) from the charging icon, then gives the "Device software can't be checked for corruption..." message
4) followed by the red Huawei logo, then a single vibrate and then back to step 3 above
5) removing the watch from the charger stops the boot loop but then shows the low battery icon (white battery with one bar).
In one or two occasions, I saw it boot up to the colorful spinning 4 android wear logo, but did not complete (did not show "Android Wear" before rebooting again.
I have tried getting it to recovery mode screen or fastboot but without success -- I keep getting the second buzz without fail.
When the beta of 1.5 came out, I tried it, but since then, have wiped my mac and don't have the adb/fastboot software anymore. From reading the forums, there is now some new software called TWRP. Please advise what I can do.
Would I be right to suspect that it is some battery problem? Is it beyond help? :crying:
Thanks in advance!
MMM
Edit: I have also left it on for several hours charging (and rebooting constantly), thinking that perhaps it is just low battery -- but no success.

I'm experiencing the same problem, i turned it off yesterday at 17% and connected to the pc this morning to charge. I immediately noticed that it started looping with the white icon and it doesn't turn on, nor boots into download mode.
Have you found any way to restore it?
Mine doesn't show the red HW logo, charged for some hours and nothing.
I noticed that the pc see that there's something connected, but keeps saying "USB not recognized". I don't know what to do, i may open up and disconnect the battery
EDIT: SOLVED, it was just the cable that broke somehow. I soldered a new cable to the circular base but that didn't work, but as soon as i received this i connected to the pc and started pressing the button randomly till it showed the battery logo and started charging

I got this when I plugged it into my laptop. Plugging it into a dedicated USB charger solved my problem - I suspect the power rating on the USB socket wasn't high enough to charge effectively or that the USB socket is faulty in some other way. From what I understand, not all USB sockets are equal in that some are suitable for high-drain devices, some not so much. So trying another USB port on your computer may also help (Unfortunately at the time I was backing up to an external HDD on the other USB so that option wasn't open to me).

guyz, i have tried my method it actually worked on Xperia X Perfomance
When it goes to Bootloop for Drained battery, i just plug the cable and perform activity block method By pressing and holing power and both volume up and down and when it hits the 1st viberation i just simply release the key. (remember dont hold it too much long after 1st single viberation just release the keys ) and your phone will go to block activity mode. charging light will change it colors from red to blue.. after 2 minutes just press power button then you ll get another viberation and your phone will be seen as charged 2% and then it will be normal again...
i think it happens when battery drained and phone is unexpectedly trying to go boot in first place.
thank you
