[HELP] Boot loop! Can't access Recovery - Android Q&A, Help & Troubleshooting

Hey everyone, my rom port went totally wrong.
I installed the cwm recovery and could access to it by pressing Volume up + power. (installed and restored stock roms a few times before)
After installing a custom rom, the phone kept boot looping, it shows manufacturers logo, and then reboots.
I've tried any kind of key combination to access recovery, but with no luck, If i connect to the PC, it detects for a few seconds, and then goes away since it reboots, so theres no time to install its drivers.
Removed battery from phone for 1 hour and tried again, still boot looping.
Don't know what I can do anymore, what are the chances to revive the phone?
If that helps.... its a china phone, running 4.2.2, 3.4.5 kernel. Bricked when ported MIUI V5 SM-N900 V1 (yeah I know its for that specific phone, but always had in mind that I could access recovery any time I wanted to restore :/ )
Regards.

Is it a MTK based phone? If so, then you'll need to find the original firmware and use the SP Flash Tool.

yes, forgat to mention it, MT6582

You'll have to find the original firmware. That can be a pain with generic Chinese phones. Good luck...

I used before Mtk_Droid_Tool to backup, so I guess I have the firmware backup?

What is needed to fix?

See if your imei and/or baseband are null. If it's the IMEI, you might be able to rewrite it with Mobileuncle app. I've fixed a couple mtk phones with it. Not sure if it supports yours...

Yes just fixed, had to put the IMEI that was on the back of the phone :victory:
sorry to bother you, thanks again!
edit: think is it possible to update my kernel 3.4.5 to 3.4.67?

No bother. My suggestion worked then?

That china application had a function to change IMEI, they were null as you said, and I just manually wrote in them what was in the back of the phone case :good:
Now talking about other issue, do you now if is possible to upgrade kernel versions? like 3.4.5 to 3.4.67? having a hard time to find someone confirm me this....

Only if the manufacturer put out an update. It's very difficult to update the kernel without the manufacturer releasing the source code, and they usually never do for devices like that.

[SOLVED] Boot Loop [Cant acess Recovery mode] Galaxy Ace s5830

Problem was solved by taking it to samsung service!

Hello,
I dont know IF posting in the right place, but I searched the whole forum for a proper answer how to "unbrick" my boot loop-ed Samsung Galaxy Ace S5830..
Now I've tried installing several firmwares using Odin multi downloader v4.83 but none of them helped me, after all I cant access Recovery Mode!
I can acess Download mode, Emergency Dmod (arm9) and RAMDUMP (arm9)
I have: Android 2.3.3 GingerBread on T-Mobile Carrier (Hungary)!
How did I get here: rooted with SuperOneClick 2.3.2 and used an app for unlock (Galaxy Ace Unlock.apk) witch was probably the main source of the problem... Had no problems until I decided to reboot, rebooted successfully, the problem I had then was No carrier, then tried a second reboot and ever since then I'm stuck into a boot loop with no access whatsoever to RECOVERY MODE.
After installing firmware and waiting the 5 minutes in Odin, my device reboots intro a boot loop after about 2:32 min and nothing can be done furthermore...
I've serched the forum and found that data.rfs is missing in the firmwares... maybe that the source of the problem to... I dont know...
Please help me fix this problem!! Thank you!

You have done everything you could and it's still not fixed (even the things other people did when they had the same problem - it worked for them, but not for you), so warranty is the only other way to get it fixed (or at least replaced).

Thank you for the help Theonew! Appreciate! I've taken it into warranty service, hopefully they wont find my device inappropriate for free service, and so I dont have to pay for it...
The only problem is that I have to wait at least 8 days untill I get it back..
Anyway, I've researched this Galaxy Unlock apk. and it seems thats the main source of the problem.

My phone also encounted the same problem after flashing Custom ROM from needrom.com. Did you make a full backup of your phone? If not then it's too bad and you might need to sent your phone back to service center.
You can try this link for tutorial and see if it works to recover your IMEI and baseband, if not your last resolution is send back to service center.
http://lenovop780en.blogspot.ro/2014/01/faq.html
And after your phone back from servicing, next time remember make a full backup incase anything goes wrong. Post #3

Hi,
I think u need to flash your rom once again.
Use flash tool to install the same.
But before that connect your phone
and go to format- format whole flash-ok.
For this u need to select the scatter file from your firmware.
After this download your firmware( not firmware upgrade)
also click on check box for D/L.
After flashing new firmware you need to use above steps which I described earlier.
Good help you.

Hi I wonder have you resolved your issue or not? Actually I found a consider temporary solution.
With your phone rooted, using any root explorer, navigate to /data and copy the nvram folder to your memory card (as a backup). Then delete the whole nvram folder in /data. Wait a while, your phone should have signal and baseband already. If works let me know, I will tell you what to do next step.

Hello, The rear camera of my lenovo doesn't work. It is model 2014 and after downgrade from kit-kat it just stops. I saw in some forums, that I have to change the apk file for the camera, but can't do it. Nothing happens when I install it normaly. Some say, that it has to be instalet via total comander or recovery consol. But I don't know how to do that. Any ideas?

Hi. Your phone is made after 07.2014. It is a new hardware for camera. Try to study the forum in development area and see what firmware is compatibile for your phone.
There are some patches for this problem.
Yes, it's rooted. The downgrade was hard at first, because I used flash tool, that is not wright and the phone won't start. But when I found the wright version, it was wasy.
Camera works with kit-kat, but I don't want to use it, so I have to find something older to use.

I don't kno how to see which type of recovery I have. But I think, that there is a problem with it. As I sad, nothing installs via this method.
I think, that the recovery comes with row s136. I installed some type of CMD recovery ver. 6, but after I try to use it, the second time the phone brokes and it won't star. So I have to flash again with row s136. Maybe I have to change the recovery with some other?

TWRP is looking like this picture.
Do you have recovery like this ?
No. Mine was with the android robot on his back. I installed TWRP, than use it to install the fix file. Everything looks ok. After that I have message in the consol, that my phone wasn't rooted and if I want to root it. I swipe for yes, reboot and now it freeses on the lenovo logo... I have to flash again.
Second attepmt - the same. Something makes the phone to stop working, after I use recovery.
On the 3-4 attept I succeed to install some things, including CameraFixFull 15 - 08.2014 phones.zip - [Click for QR Code] , but nothing changes. I think, that maybe the recovery is not rigth? It says, that the instalation is successifull, but nothing appears to be changed.

Problem with TWRP

EDIT: The problem is fixed, the problem was my dead SD card, as soon as I took it out and boot into TWRP the recovery has been working well. Thank you all for your help anyways.
What's going on guys, today I'm in need of some aid. Couple days ago I was trying to swap ROMs from PsyRom to FlyMeOS and when I tried to access TWRP recovery, it would get stuck on the TeamWin logo. I softbricked my phone by restoring the stock recovery and kernel (lol) and flashed the latest Fastboot ROM. Now I'm fine with MIUI8, and I flashed TRWP again (with Fastboot flash) but everytime I try to access TRWP it gives me that stuck logo or a black screen. I don't know what to do because I already tried with a rooted Dev ROM and flashify and even the TWRP Manager but I can't get anywhere. Do you know what I can do?
I've seen several TWRP versions for RN2.
Did you try with the official one?

AFAIK the bootloader is not locked.
Otherwise I think that you can't even install TWRP.

I have no problem with it (MIUI8). To be honest, I don't think any of them should cause the problem that you are having. Trying to solve the problem without identifying the cause will probably prove unfruitful. How did you install the first one that you had problems with? Did it ever work at all? If so, when did it start malfunctioning?

Yes it used to work, I already tried a lot of ROMs, I had the one compatible with Android 6.0 which I flashed with TWRP itself (It worked since I flashed CM13 with it).
I don't really know when it started malfunctioning because the last time I made a backup was at least one month ago when I swapped to PsyRom (it was functioning well). But two days ago when I tried to access it to change to FlyMe it wouldn't work. Anyways I'm flashing a MIUI7 fastboot ROM to see if it works.
I'm sorry if I can't explain myself very well but I'm doing the best I can lol. Thank you for your help too.
Perhaps something messed up your file system or partitions. If all attempts don't work, then you might want to use the SP Flash Tool to flash a compatible ROM and working TWRP.

Hello, after one month the issue is still not fixed, the recovery still hangs. Perhaps you could send me that fastboot rom you talked about please? Thank you.

Are you try to install TWRP from Mi recovery?
This is not going to work anymore.
You should better stay with the last ROM and flash TWRP from fastboot.

Just start your RN2 into fastboot (vol down+power on), run fastboot flash recovery twrp.img and finally keep pressed vol up and send fastboot reboot and wait with the key pressed until it enter TWRP.
BTW:
in the official forum there should be a thread with link to all officially released ROMs for RN2.

Hello, after one month the issue is still not fixed, the recovery still hangs. Perhaps you could send me that fastboot rom you talked about please? Thank you.

Here you should find every MIUI Global ROM released for RN2:

I just realized that the one I have is China version, used just to clean the phone from reseller ROM.

I'm going to send you the link.
In the meanwhile...reading the thread again...what is "update.zip method"?
Are you try to install TWRP from Mi recovery?
This is not going to work anymore.
You should better stay with the last ROM and flash TWRP from fastboot.

The problem is I already tried the fastboot method as well, and the problem is always the same, stuck TWRP logo. Even if it was a partition problem, flashing the fastboot ROM should fix it, but it didn't. I tried the SP Flash Tools method too, and the flashing methods are successful, they all Flash TWRP, but when I try to access it it's stuck. I don't know why this is happening, it used to work.
@kiko9895 Sounds like you have screwed your partitions. You will need to load a full ROM using SP Tools to correct it as this is the only way to set the partitions back at their correct memory locations. Fastboot and Recovery rewrite the partitions by name not memory location so any fault in that will never be fixed. If you have flashed an Android 6.0 based ROM or something intended for another model phone, this will definitely be the case. Anyone flashing custom ROMs should first gather the skills and tools to recover from disasters - luckily, MTK based phones are virtually unbrickable!
As far as the "official" TWRP goes, it is not official and not a good version. It is just someone who has used the TWRP build server to knock out a random version. How does that make it "official"?

Ahah I have the skills and the tools, I've been flashing ROMs for more than two years. This never happened before. If you read what I said before on this thread, you'll see that I already flashed a new ROM through SP Flash Tools. And yes I flashed a 6.0 rom before so that must be the problem, but since I already flashed a fastboot rom through SP Flash Tools I can't see where the problem is. The partitions should be fixed by now but that isn't the case.
@kiko9895 Sorry if it sounded like I was coming down hard on you. You should only need to flash a matching preloader, uboot, logo plus TWRP recovery using SP Flash Tools with the correct scatter file to get back into booting to TWRP. Any other problems can be sorted from there.
I will attach a known good scatter file because I know there are several floating around that will reverse one or two partitions on you (such as the RN3 version)

Question Lost IMEI after root

Hello all, I was asking if you can help me with an issue here.
While trying to root my Nord 2, I flashed the wrong boot.img version (A.10, while I was already update at the A.11), losing my WiFi and Bluetooth. So to recover them, I flashed the Full A.07 firmware and went back up to A.11 flashing the various OTAs. After flashing the A.07 firmware though, I've lost IMEI and Cellular functionality, and was never able to recover them.
I've done a backup of my nvram, nvdata, and nvcfg partitions before flashing, but restoring them didn't solve the issue.
I've use this guide for root: https://forum.xda-developers.com/t/root-tool-oneplus-nord-2-oxygen-11-3-dn2103_11_a-xx-eea.4332959/
And this guide to flash A.07 and OTAs: https://forum.xda-developers.com/t/oneplus-nord-2-oxygen-11-3-dn2103-eea-rom.4331695/
Does someone have any hints? Or should I send it back to Oneplus?

You done the mess even I creted simple twrp and root method you choosed the patched boot.img way and This happened.
Try to restore your full backup of nandroid using twrp. Or fist install twrp and flash non patched boot images using twrp itself

Yeah I saw there was 2 different guides, I went with the newer one but it wasn't the right choice.
Already tried flashing a stock boot image, no change. Didn't do a Nandroid backup before hand, that's my bad.

Those images are the first I've tried. I've then tried with the stock boot image linked in @pankspoo post, but with still no result. My guess is that flashing V.07 on top of V.11 rewrited some others partitions that should have not be touched
Well i am not happy to tell you, but if its true that partitions containing IMEI and WiFi connections got overwritten with nonsense information then the only thing that could save your phone is full nandroid backup which you do not have. And unfortunetly dont expect anyone else to provide it as that would mean that those 2 phones would have the same IMEI and MAC address.
I would suggest that you flash stock image, lock your bootloader and send it for RMA saying that you dont know what happened. You will have like 50/50 chance that they will just replace your motherboard without much of an investigation.

Yeah, I've already contacted OnePlus and I'm waiting for an RMA.
There's just a catch: I'm not able to re-lock the bootloader without getting the "boot image is corruptd" error. But I hope it's not an issue if I send it back all stock, with just the bootloader unlocked.

Did any way you can flash stock. Firmware using sp flash tool of mediatek just like qualcoms MSM tool used for hardbricked devices

Well my guess is that if they take a look at it and the bootloader will be unlocked they will send it back to you rejacted. Atleast that was my expirience once with my old Xiaomi phone. So probably try flashing original firmware using some kind of recovery utility such as Sp flash to help get rid of this message?

I would like to use Sp flash but I don't know where I could find the files for the Nord 2 to use with it. Like the scatter file and the firmware in Raw format
