Ok, so I recently got a problem that I've never had before, A rom installation went through fully on TWRP manager but when booting the rom, I get boot errors. I can go into download mode and thus fix the phone however, If I hold the power and vol lower button then it just restarts and has the same error then followed by a blank black screen. The issue is, I don't know if it charges in this mode or not when plugged in, I only had 50% battery life when the rom failed and I don't want the flashing of a stock tot file to fail leading to a solid hard brick. Any ideas?
Thanks.

it does charge just like when plugged in mtp mode but it charges at a slower rate so you can try leaving it plugged in for a while(or plug into wall charger for at least an hour and then attempting the flash back to stock

Looking for some help, my phone broke so a friend gave me his old g1 that has been rooted. when i power on the phone i get stuck in the boot cyctle of the g1 logo and then off and the repete.
i cant get the g1 to do a restore, the only change i can get is when i hold the back key when i turn it on. i get the rainbow scree and "serial 0" cant get into fast boot....
if possible i would like to get this device usable and even better with a cstm rom and froyo or what ever is reccommended.
any help would be amazing.

Guys,
This happened as I woke up this morning. Saw my phone showing the screen of battery charging when being switched off and looping back in the same. The phone won't restart. Tried flashing JVB from download mode but the moment phone is switched off. The same battery charging screen shows up and the phone doesn't boot up. Kindly provide some expertise on the same. Thanks in advance.
Just Checked: It'll boot up when connected to a charger but otherwise it wouldn't boot up. All this is on JVB haven't tried going cyanogen yet.
So can you or can you not enter download mode?
try remove battery and wait 5 min.,than try again
Hey Guys,
My phone gets stuck in a bootloop if I don't use a charger while turning it on. Actually, doesn't even get past the splash screen and reboots every 1 to 2 seconds. I also need to connect it to the charger to access TWRP. Normally, when I disconnect the charger after the phone has turned on, the phone suddenly turns off. But when I do the same when I'm in TWRP, nothing happens and I can continue using it without any problems. I'll put the logs if you neeed. And yes, I don't need the charger to get into fastboot mode. I'm currently on lineage 15.1 unofficial but the problem persists over other roms too. Please help...
Change the battery
It's the battery , which is under performing with the voltage needed to run the rom process,
That's why you are able to use with charger and got bootloop without charger. In twrp or any recovery mode most of the hardware is disabled and does not need much power.
Telling you with personal experiences

Thanks!! It worked.. I got my battery replaced and not my phone is as good as new ?
So, I rooted and tried flashing the stock ROM (from Sammobile, same country, same exact model [SM-G950F], I already had the stock ROM and had never flashed anything else to the phone other than root, June security update, my phone had July's) to see if I could fix a problem that couldn't be fixed with any other method I had tried.
Everything in Odin seemed to go well, I got the PASS green box at the end. But then the phone couldn't go pass the Samsung logo when booting up. I left it quite a few minutes, before trying to boot into recovery mode and wiping data. Only to realize that I couldn't boot into recovery mode. In fact, I can't even turn the phone off. No combination of hardware keys works other than power button + bixby + vol down, to get into download mode. But that's of no use, because when I plug my phone into my PC (with the same cable and port I used before to root and flash the firmware into it) it is not recognized by Odin or the PC.
It just has the Samsung logo flashing slowly over and over because I can't turn the device off. By the time the battery dies out I'll most likely have the logo burnt into the display.
I also haven't been able to find any help online. Everyone's suggestion is “boot into recovery and wipe data”, but I can't do that.
Is my phone gone for good?
Hi guys,
After googling it I tried booting it in recovery and fastboot mode but none of them work, when I try to boot in those 2 modes I get a screen with "recovery mode" written for 5 secs then it goes back to the normal boot screen and then turns off and starts to bootloop again the only way I could stop it from boot looping was by pressing the power button + the + and - buttons, so yeah if you guys have any idea how I could fix this or how I could recuperate my data please help, also it started bootlooping during the night while it was charging it was very hot when I took it, last thing when I try to go and charge it there is not indicator that it's charging.
Thanks in advance for your help !
much love

Kind of the same issue here.
Yesterday, I was using my phone while it was charging (low battery), and suddenly : freeze then power off and stuck into a bootloop.
It did it all the night until no battery, now when I plug it the charging Led is not lighting, and stuck in a bootloop.
Tried to flash TWRP vi fastboot mode : success but impossible to boot into recovery mode, as you described.
Affraid of the battery has died...
Flashed wrong orange state zip
Same to mine, my device was x651 and i flashed an orange state zip file intended for le 2 x620 without wipe and after flashing it from recovery , I rebooted the device, now its powering on and off on a dead screen and only long vibrates, how can we fix this? Please help
Not sure if this will help, but I ended up with a perpetual boot loop on the phone and wrote it off as broken and got a new one....a year later, I plugged it in to see if it would even power on so I could trade it in and VOILA, it boots up! What the hell? So my suggestion is maybe to let the battery run ALL the way down and then a long charge first.
