Please help

I just got a new g1 and after i registered it everything i click flashes on the screen then closes real fast. i cant even power it off becuz i will say the device options menu and it will close.
did you try pulling the battery to force a reboot?
yes i did and now im stuck at a caution screen
you need to give more details.... rom: modded or stock. if modded, which one
use proper grammar (or atleast so its descriptive and readable)
give more details on whats on the screen
Okay, I am sorry for the grammer. I bought the g1 off ebay and figured out how to use adb to activate it with wifi. I then started using the phone and everything would close as soon as it opened. I think it is a regular tmobile stock rom and i downgraded it to rc29.
maybe this will help you put your mind at ease

never mind, that might have made it worse
OMG HE DIED?!?!? WTF WHEN!??! HOW?!?
if your running the regular rom idk what you can do other than reflash your rom
find 1.6tmobile ota update and flash it. its probably caused by permissions issues
but theres no way to fix it without root
so you do or you dont have root? what screen exactly are you seeing when you take the battery out and turn it on?

[SOLVED] Suddenly my Xperia T has no signal

From yesterday on my Xperia T doesn't have any signal, I cannot search a Network neither. I don't know why or how happened, just did.
I clean-flashed the 4.3 Stock Rom with Flashtool but it doesn't work. I'm going to try to switch SIMs with my girlfriend so I can see wether it's a phone or SIMcard problem. Any hints about this? Never happened before
Well, it's my phone's problem, my SIM has signal in my gf's phone but her SIM doesn't have signal in mine
I fixed it.
To anyone else having the same problem:
1. Shutdown the phone.
2. Disassemble the phone. There are plenty of tutorials if you don't know how.
2. Find this connector and unplug it.

3. After a few seconds, plug it back again (when you do, you should hear a 'click' sound)
4. Reassemble the phone.
That should work, at least did work for me. This is the second hardware problem I had (the first one was the battery not charging offline issue) and both of them were just fixed by detaching and plug in back their respective connectors. If I would have sent this to Sony i'm sure they would have asked me to pay a lot of money for repairing it.

[GT P1L] Issue on kernel and also while flashing OMNI

Good morning.
Recently, I've been trying to adventure myself into flashing a working 4.4.x rom on my device but only faced problems so far - managed to get it back on stock working as intended, but still would love to have it on Kitkat. So anyhow, I found issues while flashing a working kernel to run cwm properly, found about three diferent ones but the touchscreen won't work after flashing them - even after flashing a rom. I am going to try tonight Overcome's kernel and a suggestion I read while searching, to extract a .tar from the rom's zip and flash it individually (not sure if it will work).
Also, omni seems weird on my device - after flashing it, it will automatically go into encryption request and I have no idea why (remembering that touchscreen isn't working).

Could anyone care to enlight my path onwards? Thank you in advance!
P.S.: The omni instalation above didn't go through due to not flashing gapps I believe, but the touchscreen didn't work at all.

[HELP] i9305 Bootlooping and ODIN Stock firmware fails

Hi All,
I'm looking to fix this S3 from this boot loop problem. It ended up in this problem from use, not by firmware changing.
ODIN Fails almost immediately when trying to Flash.

I've used the Firmware file name: I9305XXUFNI3_I9305DBTFNI3_DBT from a XDA forum page
This was running Stock Firmware (Grey Import) with root via Framaroot. No Custom Recovery or any Custom changes like Radio firmware).
Before my replacement phone arrive, I had a very similar problem one day and I attempted to do an ODIN Firmware flash to recover, it failed to flash then also but must have done something because my phone continued to work for another 3 months.
I have recovered everything I needed during this time but now I want to get this phone working again.
I can't see anything physically wrong with the phone and there isn't any water damage. I disassembled / re-assembled to check for any internal damage.
Please guide me where I should proceed from here.

My Leeco Le S3 X522 Qualcomm died?

Hi, how are you guys? Good night.
It turns out that I had a problem with the installation of the magisk application, when it asked me to flash it, I did it and the phone was never the same again .
I was googling and it turns out that I found this page, and downloaded a ROM that was not the version of my phone (Leeco Le S3 X522) so, when I started with the ROM, nothing on the network or anything like that worked, so here same on the page, I found the following ROM
https://forum.xda-developers.com/le-2/development/rom-pixel-experience-t3983513
But still I can't solve the problem :/.
Help, I don't know what to do.
