Utterly Stuck, Confused and a bit Desperate ! Trying to rescue Ampe A83 Tablet - General Questions and Answers

hi,
I've been at this for a few hours with no luck and i'm out of ideas.
I've got the Ampe A83 Quad Core 3G 7.85" Android 4.4.2 Tablet PC and I was trying to upgrade the stock android 4.4.2 to something newer. I figured out that the recovery needed to be unlocked before I could properly flash anything so I used the MTK Droid Tool.
Even though the link from DX states that it's an MTK8382 chip, the droid tool identified it as MT6582 and said the MTK8382 was "fake" so I started trying to look for MT6582 Roms.
I used the tool to create and install a custom CWM recovery, which worked and I can access to do the usual data and cache wipes.
I also used the tool to make a backup before i did anything else as well - it contains the various img files - boot.img, recovery img e.t.c... and everything else.
Now i've tried at least a dozen different roms for MTK devices and NOTHING WORKS. I've had a number of errors trying to install cyanogen but i've also had roms that appear to have successfully installed but when I reboot, nothing happens - the device is stuck in a boot loop but, thankfully, i can still get back to the recovery.
That in itself is no longer the issue really, because i'm now at the point where I just want to restore the device to how it was before I started trying to update it but i'm really at a loss as to what to do now.
The part that i'm worried about is that I didn't use the IMEI/NVRAM button which, seemingly, also performs a backup.
If it helps, I did use the tool to "Prepare Backup for Flash Tool", which worked, and I've downloaded the SP Flash Tool but i'm a bit hesitant to do anything at the moment in case I go one step too far and brick the tablet, partly because all of the guides i've read about using SP Flash to restore say that Preloader, and DSP_bl have to be unchecked before you do anything and I don't actually have the DSP_bl field as an option to even uncheck.
Any help would be most welcome, thankyou. Hopefully i've provided enough information.

For whatever reason, It appears I can now no longer get into recovery. I might see if i can charge it up for a couple of hours to see if that makes any difference.
This is going to be a very expensive mistake if I can't get anything back on this tablet as i'm going to have to replace it out of my own money as well considering it isn't actually mine and i was trying to update it for someone else.

Update:
It now appears to be stuck in what I can only describe as a "charging loop". I've plugged it in to mains power and I see the Battery Charging Symbol on the screen in the centre. It stays there for 10-15 seconds and then vanishes. A few seconds later it's back and the cycle repeats - over and over and over again. I can't even work out if it's getting any charge at all.
I've tried holding down the volume minus key and power for varying lengths of time but nothing happens. Same goes with the volume plus key and power and various other combinations.
It all seems to stem from when I had it in recovery earlier today and chose to reboot the system, thinking - stupidly - I could power it off. I assume since there's no active ROM on the tablet, it's basically rebooted in to 'nothing'.

I had the tablet plugged in to the mains for over five hours last night and got up this morning to see the same screen - the battery symbol blinking in and out.
I know the cable works because I used it to charge a mobile phone not 24 hours earlier.

well, thanks for all the responses but i'm going to have to consider this tablet dead now. nothing i do or try does anything now. it won't even give me the battery symbol now and plugging it in to the mains does nothing.
Maybe the battery is just dead and maybe i need a different USB cable but I can't deal in maybes when I have to now find a way of replacing this tablet.
So yeah, thanks for the help.

Pantech Burst Bricked HELP!!!

I recently picked up a Pantech Burst phone from At&t, and upgraded to ICS. I then proceeded to root the phone using the prestoroot.img method and it worked. Everything was running dandy until I got the VM Heap tool app and(stupidly) set the vm heap to 52m and attempted to reboot... It failed and all I got was a loop of boot up animations. I tried several times to reboot, and then tried to boot to recovery mode and factory reset. That worked, but it STILL didnt reboot..! I dont have a backup, and whenever i try to " Install update from external storage", it just fails over and over again. I found thestock firmware and downloaded it to my external sd card and install(still to no success). Im only 13 and cant afford a new phone! PLEASE SOMEONE HEEEELLLLPPPPPP!!!!!!!!!!!!!

I tried this method but I dont get the download button to click it remains greyed out.
Is there any driver for QHSUSB_dload?
Or do I have no hope at the moment or in near future?
just don`t use ROM manager for installing recovery . usually the result is bricked phone
Yah, i remember a fastboot brick i got from rom manager (LG Optimud ME)
Sent from a 2.8 inch screen
I also just bricked my Pantech Burst the same way...using ROM Manager. Is there a way to fix this or am I out of luck? I did try the method posted at the top of this thread. It just gets locked in the S/W Upgrading screen. Any help will be greatly appreciated.

Mine did not upgrade successfully, but I have the exact same problem. On day three of waiting for a callback from Pantech on the issue. They are supposedly talking to the techs in Korea about it.
Maybe solved!

Don't know if this is going to help, but I had the problem (as I described) red S/W Upgrading and couldn't do anything. Well, after about two weeks of sitting with the battery out, I decided to redownload and rerun the Pantech update app, and lo and behold, it fixed my phone. It also installed a more up to date version of Android 4.0, I went from 4.01 to 4.04.
This is after running the updater a good 30 or so times the past two weeks hoping for anything to work, now today, bam, it works fine.
I would recommend anyone in this situation give the most recent updater a try, it may solve your problem.

Bricked Pantech Burst Stuck in S/W Downloading Mode and completely wiped ...
Ok I am having a similar issue guys. Last night I had to wipe my phone because it was overly full and I switched providers and the phone had become unusable. I tried using clockworkmod to do this and it wiped everything ( including clockworkmod. ) Now I only get a S/W Upgrading screen with a red box. I tried using the pantech download tool and the PANTECH_PRESTO_BIN_JUUS03122012.pdl file. It did appear that it was installing it but then it became stuck at the very very very end of things. I basically had to take the battery out to do anything at all as I had left the phone on all night to download the pdl file but without any luck.
When I reboot the phone it had the S/W Upgrading mode with the red screen. I've tried all of the different key combinations on the pantech burst etc volume up + volume down and power, volume down + power, volume up + power. None of these things will reboot the phone.
I am hoping I can use the pantech download tool to install a different pdl instead and possibly get it working that way. I know that when the phone is off if I plug it into usb then the screen lights up on it with the S/W Upgrading screen and the red box. If I press the power button or any other combinations of buttons + the power button it also does this. It literally will not do anything else.
I cannot use pantech pc suite because the phone originally was so unusable I could not put the android apk file on the phone even though I have it on my laptop.
I tried using adb and fastboot and it will not even find my device through ANY usb port on the laptop. I've tried deleting and reinstalling the drivers over and over. The only thing I know to do is reboot afterward and hopefully it will find my phone on usb with adb. If I can just get to a bootloader or flash functional firmware onto this phone I think I could get it working but I do not know enough about the pantech burst to try physically jumping anything on it in order to hard reset it.
So my only options right now look like maybe get a different pdl, possibly reboot and the drivers may find my phone, or JTAG this thing.
I can't put it in usb debugging mode because it won't boot. Since adb does not even find the device as being attached it seems as if this phone should be operating in a different port mode or something to make it visible. I could be wrong but I am hoping that rebooting fixes the driver issue and makes the phone visible.
I tried PDAnet also and once again it does not work because it cannot find the device. This could be a usb cable issue I suppose but I only have this particular cable I am pretty sure
I might try another cable as well...
Any other ideas ? Am I going to have to JTAG this thing or should it be fixable using the download tool and a different pdl ? Or do I need to find another way to completely wipe the phone first and THEN use the download tool with the pdl file ?
It does get a bit confusing with so many mods, roms, and methods to recover android phones. If I can get the phone to boot then I can reload my backups and all should be well. I do need this phone for business purposes also. Any ideas guys ?
PS> I am also pretty decent with linux distros like arch or ubuntu so I would like to also know if it would just be better to do this in linux and possibly use linux to manually switch the phone to a different device mode to make it visible in the instance of there being nothing wrong with the drivers.
Thanks for any ideas or suggestions ...
UPDATE - progress ???

OK quick update, I found the pantech burst upgrade tool and the burst-hack.cmd script
I managed to successfully find my phone with the upgrade tool and it completely ran its course and I am guessing it installed Ice Cream Sandwich.
My new problem is that the phone goes to the pantech logo boot screen if I plug the phone into usb but that is all it will do. If I unplug the phone and try to get into S/W Upgrade mode again or power it on it will not do anything at all. Basically the display only comes on when plugged in at this point so I am wondering if the battery is even charged or if it will charge. I read somewhere ( in the gizmolord forum ) that a guy had the same issue as me and he ran this tool for his pantech burst and then left the battery out for 2 weeks and tried to power it back on and it worked for him.
Is it possible that I just need to power the device down completely and let it completely discharge before it will reboot or is this thing bricked ?
I am thinking that either the battery needs to charge, or the phone needs to discharge and power down completely, or the phone could be bricked. I have a feeling it is not bricked because the update tool said everything was successful and no errors or anything.
I will try leaving the battery out for awhile and letting the phone discharge on its own and see what kind of results I get. I would think that 16 - 24 hours would be sufficient. Any ideas ?
---------------------------------------------------------------------------------------------------------------------
Ok so I did a bit more digging and research and found out that the culprit is most likely the poorly designed charging circuit in the pantech phones. I found a tech blog called Mikes Techblog where he shows how to solve this on a pantech jest phone with the same issue. The problem is that the battery is 3.7v and is currently reading 2.8v on the volt meter. The phone will not even attempt to charge until 3.7v is available on the battery because of how the charge circuit is designed. I am going to try the usb cable trick and usb adapter and see if I can monitor its progress with the voltmeter and get it back up to 3.7 volts. After this it should allow me to charge it normally and should boot just fine. It is showing the pantech logo which tells me that the firmware is there and isn't buzzing or doing anything else weird so more than likely this is related to the battery and not having enough of a charge when running the official upgrade tool. This problem probably had already existed prior running the update tool and is why the S/W Upgrading screen only would come up AFTER being plugged into a power source and would disappear immediately. If the battery had any charge whatsoever and if the phone could see it then I would see a screen that tells me to plug my phone in and charge it. I am thinking this is solved but will only know after I charge the battery. From what I've been reading in comments from others the battery issue is prevalent on many different pantech phones including the burst model. Other people with the pantech burst have said in comments on Mike's blog that this made their phone boot right up and said that this was EXACTLY the issue. Perhaps the best way to use these pantech phones is to never ever let them fully discharge the battery.

[Q] CWM on new Blu Life Play

Hi all,
I've spent a good two hours trying to figure this out. Generally I'm pretty good at these things, but there just isn't that much action or information on the Blu Life Play when things go wrong (L100a)
http://forum.xda-developers.com/showthread.php?t=2370987
In reference to the above link, I followed all instructions to a T. My phone is rooted just fine, all that is working perfectly. However, once I tried installing CWM using the first method, mobileuncle, not only did it fail, but it also entirely broke my recovery mode! Whenever I try to boot into recovery (vol+/power) I get a black screen until the phone eventually reboots itself.
I then tried method two using the flashing tool, SPFT. I used something similar pretty often, ODIN, with my old Samsung Epic. Again I run into a problem: I can't keep the phone connected long enough to allow SPFT to finish flashing the recovery. As instructed, I plug in the USB cable with the battery out, my computer chimes to let me know it has recognised the device, but- Three seconds later, it chimes again to let me know it has disconnected.
SPFT follows suit, detecting and starting the flash then getting interrupted 2 seconds later.
My phone is still able to boot, it is not bricked. However, it is very distressing to have no access to a recovery mode.
Help?
I have the same issue. Got my phone replaced under warranty and the new one I got yesterday will not boot to recovery. Only black screen. Hopefully we can figure out the issues.

Hey, it's good to hear I'm not alone in this. lopestom has been friendly enough to correspond with me about it and he suspects it's a new model of the same phone. I sent him a screen cap of the factory settings screen (VOL-/POW)
In the end we might be out of luck until more people get their hands on the new version of the phone.

[Q] Stuck at bootlogo

Hi,
I got this tablet from a friend, and it's stuck at the boot logo. I've tried hard reset, reset via recovery, nothing seems to work.
How can I flash the latest official rom?
Can't seem to find a tool for it, and Asus suggest to flash with the tablet itself, but that's not possible for now.
Anyone?
Thx!

Easyflasher to flash TWRP recovery > copy ROM to MicroSD card, flash ROM
Thanks! I can't seem to get him into APX mode, what is the exact procedure?
Connect the tab to USB > PC first
Power Off the Tab
Hold Volume Up & Power
Nothing will appear on the Tab screen, but the PC should sound the USB connect noise / device manager will show it has connected - only takes a few seconds to enter APX mode
I've tried that, doesn't seem to recognize it . Would you help me via IM of some sort?
It`ll be the drivers most likely, open device manager when its connected and in APX mode, and manually update the drivers using the Universal Naked Driver from the Easyflasher site
I don't have any IM installed unfortunately but I`ll help you out here
Ok, that would be wonderful. The problem is, I don't know when it's off. I can't get it to shut down, it keeps rebooting. I'm monitoring dev manager with sound high, but it's not coming up. Cable is working, because it will charge. Using the original cable. (Windows 7 x64)
Best thing to do would be connect it to the PC, then press and hold Power until it shuts off, then try for APX mode - you might even be able to enter APX from a powered on state by holding the same button combo, but Ive not tested that myself
And a cable that charges doesn't automatically mean it will work for Data, they use different pins, some for power and some for data, if the data pins are damaged, it will still charge
I can't seem to get it working . Any other ways to flash it?
Not without being able to get it to boot - you'll need APX mode to do anything in the state it's in now
A bad cable is a common problem though, might be worth grabbing another one from eBay
To bad. I'll try and let it drain till it's empty, and fully charge it then. Just ordered another cable.
Thx for the help!
If the System / Data partitions are corrupted, which generally causes the boot loop, then draining and recharging won't help
Plus be careful not to drain the battery to 0%, their design prevents them from recharging if they hit 0% - many people have had to buy new batteries after not using their tab for a few months and letting it drain completely
Good luck, so long as there is no hardware damage, once you have a working cable it should be pretty straight forward to get TWRP recovery and a new ROM flashed to it
Might be worth trying your current cable on another PC too
Thanks for the headsup! Will try!
Hello everyone,
Not to thread jack but I have a similar problem and instead of opening a new thread I decided to revive this one.
I have a similar problem that my TF101 has been working flawlessly for many years. It is rooted and was running 4.3 ROM. As of a couple of days ago it just won't boot at all. It has been stuck at the NVidia screen and just sits there. I tried to enter recovery mode by using volume(-) + power and the unit presents the TEAMWIN logo and just loops as well by showing the TWRP screen (3 seconds) then going blank for a second then showing TWRP screen again in a cycle.
I downloaded and tried Easyflasher and Brks toolkit and nothing can complete the flash. Tried different installed drivers as well. I can enter MTP mode which the computer can see the device but the manufacturer name and model are not-recognized. I can also enter APX mode but while trying to flash anything I get an error message (error, cannot flash bootloader) and the computer dings (device disconnects).
I have been trying for a days now and have run out of ideas.
Has the unit finally bit the dust? Does any one out there have any more ideas or suggestions on what to try next?
TIA for any help provided.
Anyone with any sort of help on my previous post? Time to retire it for real this time?
TIA

Have you tried a different / new cable in-case that's the reason all the flashing attempts and computer recognising the unit are failing ?

[Help] Super Hard Brick - Stuck in EDL and no button response at all + SHA256 fail

Hi everyone,
I'm having an issue with my 7 pro (1911). This is my 1st Oneplus as I used a Mi 5 before, the flash procedure was much easier without this A/B mess.
So I somehow messed up a new install of pixel experience with blu_spark kernel and twrp and found myself with the qualcomm crash error. Trying to get back into fastboot with the button combination (was able to save it once in it) the phone restarts and got stuck in edl mode. I noticed it's recognized as 9008 in the PC so I said okey this is nothing I'll just use the MSMTool to get it back on again.
Went through the xda Mega thead procedure, had no problem getting the phone to connect to the tool, however, first unexpected thing I encounter is the fact it stops with a SHA256 doesn't match error, and fails to send op2.img. I verified the ops file to make sure it has no errors and it was good. I then checked "disable sha256" box and it goes normally with the flash this time. Except in the end instead of restarting into the system it restarts into edl mode again and if the cable is still attached starts flashing again. This loop keeps going on forever.
I checked everywhere the only other thing I found that hints at a possible solution was doing an SMT download (based on this thread from OP6). Having an EFS backup already in one of my TWRP backups I went ahead with the procedure. Everything goes normally with the sha256 box disabled. it takes longer than upgrade mode (it flashes also to b slot), it finishes fine till the end. I disconnect the phone to boot it but it's still stuck in EDL mode!!! pressing any combination of button only keeps restarting the phone in EDL; when connected to the pc you see it going off then on in device manager.
The only idea I have left is waiting for battery to die, which could take forever and I have no idea if that'll work
Things I tried/used :
Qualcomm drivers are the latest from microsoft server v2.1.2.2. Tried some other ones but no change.
Pressing any combination of buttons (up + down + power, up + power, down + power) for multiple minutes doesn't change anything (it only hurts your fingers lol)
Before the issue the phone was at around 40%, I don't think the problem was battery charge, but I still tried connecting to official charger for some time but no boot.
I tried using multiple cables, ports (usb 3 and 2 from front of pc), tried on a laptop with both usb 2 and 3, all give me the same results, sha256 fails, without the check it flashes but no boot or response.
I redownloaded the MSMTool multiple times from both the Mega thread and newer one with oos 10 images, even the chinese image, all of them give the exact same issue. The only one that didn't work was the TMobile image, saying it's the wrong image (tried it just to be sure my phone wasn't originally a TMO converted, as it's 2nd hand).
Tried starting a normal flash in MSMTool and leaving it on that loop (flash, finish, restart again in EDL, flash...) all night but still found it flashing in the morning, never booted to system.
I found some people in the forums having the same symptomes (but quite rare compared to others), only 2 said they found a solution:
OP7P (this guy fixed the issue by charging his phone) https://forum.xda-developers.com/showpost.php?p=80329855&postcount=83
OP6T (this guy discharged his phone completely then connected it and it booted) https://forum.xda-developers.com/showpost.php?p=79079192&postcount=5
OP7 https://forum.xda-developers.com/showpost.php?p=81183765&postcount=41
OP7 https://forum.xda-developers.com/showpost.php?p=81185793&postcount=43

OP6 https://forum.xda-developers.com/showpost.php?p=79445923&postcount=203
I'm making this thread maybe someone who had the same issue can show me how he solved it, or if not and my last resort works (complete battery discharge) hopefully stays as a helpful history to someone else.
Thanks.
Hi again,
Updating my thread with what I could do lately:
I opened the phone up, anxious to try disconnecting the battery and seeing if it makes any difference. To my surprise that also did no change at all.
After some time working with NerdgOd56 from the Reddit Discord we tried many things, among them reading back the memory using MSM Tool. There was also a python script that enabled reading a provision xml file that's used by the tool to flash everything. This file mentions where in the OPS file each image is. So after some fiddeling with the OPS using a hex editor, I found that there are quite some differences with the images I read from the phone, this hints at a possible flash memory corruption. Though this needs to be confirmed by someone who has a clean phone, whether the images are supposed to be exactly the same or probably they're encrypted when transfered to the phone.
So right now I'm starting a search for a motherboard locally, hoping to find something.
Thanks to all the guys from discord who gave their time to my cause NerdgOd56, DarkPhoenix and the others on the OP7 channel.
Hi again,
Updating my thread with what I could do lately:
I opened the phone up, anxious to try disconnecting the battery and seeing if it makes any difference. To my surprise that also did no change at all.

Did you say you was able to get to fastboot mode if so jus boot twrp image then flash twrp image.zip from the xda. Then do a full wipe then download download a ota zip from xda and flash it. That's how I got out of edl mode.
ANY NEWS>?
i also have an OP6T
used MsmDownloadTool V4.0_factory_mcl_op1_patched
with
rev_OverSeas_181226_1920_release_disable_OTA-BLOCK_Signed_fp1812260627_cve2018-12-01_ufs_9.0.11
and
fajita_41_O.18_181226.ops
phone was stock.
Proceeded to flash custom rom etc.
Now since then i decided i wanted stock again to try new custom rom etc. and,
i booted twrp and just wiped everything like a mad man.
i have had this happen before.
Currently, it will and can boot into any mode such as fastboot recovery(TWRP) edl and device state/secureboot are both unlocked/enabled
TRY TO LET IT DIE AND PUT RUBBERBANDS OLONG THE PHONE SO THE VOLUME AND POWER BUTTONS ARE HELD DOWN GOOD AND LET IT SIT FOR A DAY TO DIE.
After you do that let it sit for a bit and its dead. take off the bands and let it sit for another half a day and redo the bands to make sure its been reset and is indeed complete dead. repeat, whatever.
when its surely dead and been reset, THE ONLY thing you can try is
plug it in and almost at the same time (not simultaneously, but sequentially)
YOU NEED TO HOLD VOLUME UP+DOWN at the same time RIGHT AFTER YOU PLUG IT IN LITTERALLY. And, it should display the 1plus logo briefly and boot into fastboot mode.(i had to do this after wiping rom etc via twrp an became stuck in edl mode)
from there i booted twrp
(was my reccovery still)
mind that i wiped everything like a mad man and i lost my ADB AND FASTBOOT AND AS WELL AS MY EDL MODE PRIVILEGES(2 PCs, a couple cables tried and the phone is still not being recognized in any of the mentioned modes ), and after doing what i mention if you can get into fastboot mode you may be in luck, however if you can get back into any other mode.(Or fastboot flash a stock rom, adb sideload etc)
im still here waiting my usb otg type c because the usb wont recognize with the adapter to micro usb. Now ive never had a usb otg type c adapter before, but i know i could never get the micro usb (universal) to adapt my otg with a, "type C" type adapter and see the storage device(usb) being recognized by android. So i will reply when it arrives and i can attempt to flash stock again via otg twrp with oos zip. (THIS HAS TO BE AN A10 ISSUE WITH TWRP BEING FAIRLY RECENT IN RELEASES AND CAUSING IT TO NOT BE RECOGNIZED AFTER PERFORMING A, "FULL WIPE")
hopefully the otg for usb c is going to be recognized by twrp still.
if all else fails and your still under contract warranty, just light the **** on fire and run it over and pay the $40 deductable and take it as a $40 lesson and have them send you a new one(or upgrade depending on eligibility etc.)

I don't know if you saw my last comment but I had even opened the phone up to disconnect the battery ribbon, hoping that would get it out of EDL but it didn't. However I didn't do the trick with the buttons when connecting it, I'll try this after disconnecting the battery. Also if that didn't work I'll leave it on rubber bands like you said, nothing to lose anyway. Thanks for the tips. I'll let you know what's up.
How did you know when the phone was dead while on rubber bands, do you verify if it still gets detected on the PC ?
Yeah i had did the rubberbands for a lil more than couple days and like i said i let it sit for about a day without the bands on after i had a good 20+ hours with em on then reapplied bands for about 20 hours.my phone was completely discharged during that process( OP6T).
Upon doing this i lost access to my recovery img.
Phone only boots fastboot (even if i choose recovery, it was previously working)
So now i still cant recognize in fastboot or edl.
GOT my OTG type c and put oos on usb, but as i said now my twrp isnt booting, so i shouldnt have depleted the battery as now i have no possible recovery access modes . Aside from that, im trying to figure out more info on the device and will reply in a day with what i may come to find out.
My phone did get detected because it started up as soon as i plugged into pc.
battery seems un-accessible but may have to take this apart.
I am figuring this out and i will get back to you. I need more tech assistance from a friend in the repair industry to disassemble without destroying it tomorrow or sometime friday.
This is going to have to be some sort of an intricate process to diagnose this supposed "HARD BRICK"
:Have to correct myself
talked to my brody at tmobile to see wassup with the warrenty etc.
basically its not covered under warrenty when you mess with software, blah blah i figured anyway, and he basically advises (OR more so "i didnt tell you anything like that!"- laughing) to literally run it over with your car or just smash the screen, and file the claim without issue...
BUT THE ISSUE IS ITS GONN COST YOU $99 to get a new OP6T via Assurant
your device might be the same, or even more costly,
i would prefer to avoid all costs, spending more money, not trying to..

Yeah so sad, probably the internal memory has a slight % chance it gets corrupted or something...
Since my story in the OP I bought a used 1913 that's a bit cheaper coz of external scratches and took its motherboard for my cleaner original phone. It's been working like a charm since.
hi everyone last night i plug my phone for charging after a while i came back and see crash dump mode i switch off the and try to unbrick via msm tool 1st attempt everything fine auto reboot after progress complete it stuck in oneplus logo after that i tried to redo all thing now i faced this error on MSM TOOL PLEASE HELP ME I CHANGED THE CABLE USB PORTS DRIVER REINSTALL BUT STUCK AT THIS POINT. when i uncheck sha256 downloading start but it does not stop again and phone did not auto reboot help please

op6 stuck while loading, it tries to load,then reboot,then load again..

its not the usual reboot loop, it gets not even that far, its stuck to the "this phone is jailbroken,hit power to pause" after that it just reboots,while empty.
i tried to switch it off, to ensure loading, but keeping the powerbutton 10sec pressed,is impossible,there is not enough time.
i tried to switch into the bootloader, and say switch off, well it goes back into the loop 2sec later,since it got a bit power, it tries its nonsense.
i tried differend loading methods, pc usb, usb pure (2.1mAh), and the oneplus speedloader adapter with the red cable.
what happend before, well it got empty, and switched off,the apps and such didnt change for about a year, it worked, and thats it.
the accu cell got changed about a year ago, by my insurance company, the old one balooned. so they changed it,meaning its not even a old cell.
trying fastload in bootloader,didnt help getting it charged,anything else just relooped.
iam open for suggestions.
thanks and regards

I think ur phone might be soft bricked or idk. But I'm pretty sure the problems didn't caused by the new battery.
Seems the phone didn't recognize the /system/ or something on twrp that says "There's no system installed" coz i've faced that (no system installed) before.
If u can manage boot into bootloader, try to fastboot a twrp.img and flash a stock firmware.
If u can't, or let's just say you really feel ur phone in fked up state, try to reflash everything with MSM Download Tool.
Here's some threads I found :
Soft Bricked?
I apologize as I've been out of flashing ROMs for over 4 years now. I unlocked my OP6 bootloader, added TWRP, the flashed Lineage 11. One of my apps wont play nice with root so I tried to go back to stock. I tried to use TWRP 3.5.2_9-0 to...

It is much better to state the status of your device briefly. Like are you on OOS or custom ROM, unlocked bootloader, with custom recovery installed, magisk installed, etc. Then tell the story on what you did or what happen before your phone got the issue you stated. Then maybe someone can help you in more specific way.
Like Azhar_Fahry recommended, I also recommend using MSM tool and revert back to original state like you first bought your device.
